[Example]

Please refer to Figures 1 to 4. The present invention provides a hand-made brewing device that can be suspended and supported, which can be used to brew various beverage materials such as coffee, tea, roselle tea, fruit tea or health tea. The following description takes coffee as a representative beverage material.

The hand-washing device that can be suspended and supported includes a filter holder 1 and a filter 3, and may further include a filter holder 2. FIG1 shows a common V-shaped (or cone-shaped, hereinafter referred to as V-shaped) hand-washing cup as an example 1. The filter 3 can be a commercially available product, including V1 filter paper for one-time brewing of 1 to 2 cups and V2 filter paper for one-time brewing of 2 to 4 cups. FIG1 shows an example of using V1 filter paper, but the invention is not limited thereto. The present invention replaces the V-shaped hand-washing cup with a filter holder 1. The filter holder 1 is a hollow body, and the inner diameter of the lower end of the filter holder 1 can be larger than the outer diameter of the lower end of the filter holder 2.

The upper end of the filter rack 1 is provided with a supporting mechanism. In this embodiment, the upper end of the inner side of the filter rack 1 may be provided with an upper inclined surface 11, which is inclined and surrounds a circle. The upper inclined surface 11 can be tangentially fitted with the filter paper 3, and can be used to support the filter paper 3 to be suspended on the filter rack 1. The upper end of the inner side of the filter rack 1 may be provided with a filter paper slot 12, which can be provided at the upper end of the upper inclined surface 11, and the filter paper slot 12 can be horizontally arranged and surrounds a circle. The upper inclined surface 11 and the filter paper slot 12 can form a supporting mechanism, and can be used to suspend and support the filter paper 3.

The filter paper 3 has a foaming area 31 inside, and the foaming area 31 can be used to place beverage materials such as coffee to brew the beverage materials. The foaming area 31 is located below the support mechanism, and the foaming area 31 is located below the upper end of the filter paper 3. The foaming area 31 and the upper end of the filter paper 3 form a spaced arrangement, so that when the filter paper 3 is placed on the filter paper rack 1, the foaming area 31 of the filter paper 3 can form a spaced arrangement with the support mechanism of the filter paper rack 1, and the foaming area 31 is lower than the support mechanism of the filter paper rack 1.

The filter holder 2 has a conical surface 21 at its inner center, which can correspond to a conical outer surface 32 of the filter paper 3 and is used to position the filter paper 3, so that the filter paper 3 and the filter holder 2 can be tangent to each other and the filter paper 3 can be more stably arranged. The filter holder 2 can have an outer inclined surface 22 on its outer side, so that the filter holder 1 can be easily assembled and removed from top to bottom.

A water guide 4 may be provided above the filter holder 1. The water guide 4 is provided with a plurality of hot water outlet holes 41, so that the hot water can be evenly distributed and flow down to brew coffee. The water guide 4 may have a lower ring 42. When assembled to the filter holder 1, the lower ring 42 can be used to press the filter paper 3 so that the filter paper 3 is stuck in the filter paper slot 12.

Pre-operation procedure: The filter holder 2 can be placed on the operating table, the filter holder 1 is placed on the filter holder 2 from top to bottom, and then the filter paper 3 is assembled so that the filter paper 3 fits the conical surface 21 of the filter holder 2 and the upper inclined surface 11 of the filter holder 1. A proper amount of ground coffee powder is added, and the lower ring 42 of the water guide 4 is pressed down on the filter paper slot 12 of the filter holder 1 so that the filter paper 3 is stuck on the filter holder 1 as shown in FIG. 2. Then, the filter holder 1 is lifted up as shown in FIG. 3, and the subsequent hand-brewed coffee brewing procedure is performed, and the filter holder 2 is detached and remains in the original position.

When brewing hand-brewed coffee (drinking material), hot water flows down from the water injection hole 41 of the water guide 4 into the coffee powder. During the brewing process, the coffee powder will expand and the water level will rise. Regardless of manual brewing or automatic brewing, the amount of hot water should be controlled appropriately so that the highest point of the brewing water level is below the reserved space so that the coffee liquid will not touch the paper filter holder 1 and the water guide 4. After the brewing process is completed, the entire filter holder 1 is moved to the top of the coffee grounds container, the water guide 4 is taken out, and the filter holder 1 is gently shaken, and the coffee grounds containing water in the filter paper 3 and the filter paper 3 fall into the coffee grounds container, completing the last process of hand brewing coffee. The filter holder 1 and the water guide 4 are kept clean because they are not stained with coffee liquid at all, and the next brewing process can be carried out without cleaning.

Filter paper holder 1 embodiment 2: The difference from embodiment 1 is that the filter paper holder 1 of this embodiment has no filter paper slot. The filter paper holder 1 of this embodiment has the same upper inclined surface 11, which can be tangent to the conical surface of the filter paper 3. As shown in Figures 5 and 6, after the filter paper 3 is installed and then a proper amount of coffee powder that has been ground into a suitable coarseness is put in, the upper end of the filter paper 3 protrudes from the filter paper 3. The upper end of the paper rack 1 protrudes from the filter paper 3 on the filter rack 1 (as shown in FIG. 6 ). Press the upper end of the filter paper 3 with your hand and fold the protruding filter paper 3 downward. After folding the filter paper 3 360 degrees, flatten it. It is also possible to fold the filter paper 3 flat first and then put the coffee powder. In order to facilitate the folding of the filter paper 3 that exceeds the upper end of the filter rack 1, a larger filter paper can be selected for the filter paper 3, such as V2 filter paper for brewing a single cup of hand-brewed coffee. After the filter paper 3 that exceeds the upper end of the filter rack 1 is folded down and flattened, the folded filter paper 3 is hung and clamped on the upper end of the filter rack 1 (as shown in FIG. 7 ). After the coffee powder is actually loaded and hot water is added to brew coffee, the tension of the folded filter paper 3 will make the filter paper 3 clamped on the upper end of the filter rack 1 and will not slide.

As shown in Fig. 7 and Fig. 8, the inner diameter of the lower ring 42 of the water guide 4 is larger than the outer diameter of the upper end of the filter paper holder 1 on which the filter paper 3 is installed, so that the water guide 4 is easy to be installed on the filter paper holder 1 and has a pressing function, so that the filter paper 3 in the brewing process is more firmly fixed and does not fall off. The lower ring 42 of the water guide 4 can be slightly larger and rounded, so that the water guide 4 is easier to assemble on the filter paper holder 1.

As shown in FIG9 and FIG10, the third embodiment of the filter holder 1 is different from the first and second embodiments in that the present embodiment has no filter paper slot and upper inclined surface. In the present embodiment, an upper ring body 14 may be provided at the upper end of the filter holder 1. The upper ring body 14 surrounds the upper ring body 14 into a circle. The upper ring body 14 may form a supporting mechanism. The upper ring body 14 can contact the outer side of the filter paper 3 to suspend and support the filter paper 3. The operation steps are the same as those of the second embodiment and will not be described in detail.

As shown in FIG. 11 , the fourth embodiment of the filter holder 1: the brewing filter paper for hand brewed coffee, in addition to the V-shaped filter paper, another commonly used type on the market is the T-shaped filter paper. The filter paper holder 1 of this embodiment has the same filter paper slot 12 as that of the first embodiment. The filter paper 3 uses the T-shaped filter paper. The inner dimension of the filter holder 2 corresponds to the outer dimension of the T-shaped filter paper, so that the T-shaped filter paper can be tightly attached to the T-shaped filter holder 2. The operation execution procedure is the same as the previous embodiment and will not be described in detail.

The above four filter holder embodiments all use the filter holder 2 to assemble and position the filter 3. After skilled operation, the filter 3 can be assembled and positioned on the filter holder 1 without the filter holder 2. Therefore, the filter holder 2 can be used or not, and can be omitted according to the situation. The main design feature of the filter holder 1 is that the brewing area 31 of the filter 3 is suspended, and the brewing area 31 is lower than the support mechanism of the filter holder 1, so that the filter holder 1 will not contact the coffee liquid and can be kept clean. It can continue to be used without cleaning after use, which can ensure no food hygiene problems.

Brewing Example 1: As shown in FIG. 12 , this embodiment provides a brewing mechanism for brewing coffee in places where there is a lack of water and electricity, especially outdoor coffee carts. Cleaning of coffee brewing equipment is a major problem. Hot water for brewing coffee is commonly supplied by a generator to the coffee machine heater and operating power supply, which is inconvenient and the noise of the generator is a disadvantage. Improvement method: A thermos 5 is filled with boiling hot water. The hot water source can come from a hot water stove, or an external heater such as a gas stove is used to heat the hot water kettle to boiling and then pour it into the thermos 5 for standby use. The thermos 5 can have a manual water outlet valve 51 to keep it in a long closed state.

The thermos barrel 5 has a control device, which can be a manual water valve 51. When the manual coffee brewing process starts, the manual water valve 51 is turned to a long open state. The manual water valve 51 is connected to an electromagnetic valve 52. The electromagnetic valve 52 can be locked at the outlet end of the manual water valve 51 by a butterfly nut 53. The butterfly nut 53 is used to store hot water or clean the thermos barrel 5. It can be manually disassembled and assembled. A leak-proof gasket can be provided in the butterfly nut 53 to keep the electromagnetic valve 52 and the manual water valve 51 watertight. The electromagnetic valve 52 is powered by an external DC battery. The DC battery (or battery) is a commercial product (not shown, the same as the following description). If the wash-free foaming mechanism of the present invention is used indoors, it can directly use AC power, and the hot water source can also be a hot water stove.

The hand-brewed coffee utensil can be any of the above-mentioned embodiments of the paper filter holder 1. The brewing mechanism can also include an electronic scale 6. A brewing holder 7 is locked on the electronic scale 6. The brewing holder 7 can position the coffee cup (cup) when it is placed. The front end can be open to facilitate the placement or removal of the coffee cup. The coffee cup can be a commercial product. The upper end structure of the brewing holder 7 corresponds to the outer diameter of the lower end of the paper filter holder 1, so that the paper filter holder 1 can be smoothly placed, positioned or removed.

The electronic scale 6 may be provided with a metering display 61, which usually displays the brewing amount in C.C., a timing display 62, which usually displays the brewing time in seconds, and a plurality of operation buttons 63. Each operation button 63 has a built-in automatic control system to execute the brewing process of different beverage materials. The automatic control device can be installed in the electronic scale 6. The electronic scale 6 and the automatic control system are powered by DC batteries. The DC batteries (or batteries) are commercially available (not shown, the same applies to the following description). If the wash-free brewing mechanism of the present invention is used indoors, AC power can be directly used.

Operation steps: For example, the brewing program can be set as follows: 20 grams of coffee powder, a total brewing volume of 300CC, four stages of brewing, 50CC of water in the first stage, 40 seconds of steaming, 80CC of water in the second stage, 80CC of water in the third stage at 70 seconds, 90CC of water in the fourth stage at 110 seconds, and the hand-brewed coffee brewing program is completed at 150 seconds.

The pre-installation operation of the hand-poured coffee maker is as follows: after the filter holder 2, filter paper 3, coffee powder and water guide 4 are installed on the filter holder 1, the hand-poured coffee maker is lifted and installed on the brewing holder 7, the filter holder 2 is detached and left in its original place, and the coffee cup is placed at the positioning position below the brewing holder 7.

By pressing the preset operation key, all load measurements and timings on the electronic scale 6 automatically return to zero, the automatic control system starts the electromagnetic valve 52 to discharge hot water, and at the same time the electronic scale 6 starts measuring and timing. When the hot water output reaches 50CC, the automatic control system closes the electromagnetic valve 52. The timing device starts the electromagnetic valve 52 at the 40th second. When the hot water output reaches 130CC, the automatic control system closes the electromagnetic valve 52. The timing device starts the electromagnetic valve 52 at the 70th second. When the hot water output reaches 210CC, the automatic control system closes the electromagnetic valve. 52, the timing device starts the electromagnetic valve 52 automatically at the 110th second, and the automatic control system closes the electromagnetic valve 52 when the hot water output reaches 300CC. The timing device sends out several sounds at the 150th second to indicate that the hand-poured coffee brewing process is completed, and the beverage cup proceeds with the subsequent seasoning addition process. The hand-poured coffee utensil is lifted above the coffee grounds bucket, the water guide 4 is removed, the filter paper holder 1 is gently shaken, and the filter paper 3 together with the coffee grounds are transferred into the coffee grounds bucket. The hand-poured coffee utensil does not need to be cleaned and is put back into the storage position for standby use, completing the hand-poured coffee free-washing brewing process.

Brewing Example 2: As shown in FIG. 13 , the thermos 5 can also be directly equipped with an electromagnetic valve 52, which is a control device. The electromagnetic valve 52 is powered by a plug 54 connected to the electromagnetic valve. The purpose of using the plug 54 is to unplug the plug 54 when the thermos 5 needs to be filled with hot water alone, and then the thermos 5 can be moved.

The coffee powder can be ground to a suitable coarseness in advance and packaged in a quantitative manner. A barcode can be printed on the packaging bag. The barcode can be a one-dimensional barcode or a two-dimensional barcode. The automatic control system sets the brewing program of the hand-poured coffee according to each barcode. After a barcode scanner 8 scans and reads the barcode on the coffee bag, the automatic control system memorizes the barcode and builds in the hand-poured coffee brewing program to be executed.

The electronic scale 6 is provided with a metering display 61, which usually displays the brewing amount in C.C., a timing display 62, which usually displays the brewing time in seconds, and a start button 64. After pressing the start button 64, all loads and timings on the electronic scale 6 are reset to zero, and the automatic control system executes the brewing process of the beverage material according to the barcode information on the coffee bag scanned by the barcode scanner 8. The automatic control device can be installed in the electronic scale 6.

Brewing procedure: Assume the brewing procedure is as follows: 20 grams of coffee powder, a total brewing volume of 300 CC, four stages of brewing, 50 CC of water in the first stage, 40 seconds of steaming, 80 CC of water in the second stage, 80 CC of water in the third stage at 70 seconds, and 90 CC of water in the fourth stage at 110 seconds.

Pre-operation of hand-poured coffee equipment: Place the coffee bag under the barcode scanner 8 to read the barcode information, and the automatic control system will memorize the hand-poured coffee brewing program set by the barcode and wait for execution. Install the filter holder 2 and filter paper 3 on the filter holder 1, tear open the coffee bag and pour the coffee powder into the filter paper 3, install the water guide 4, lift the hand-poured coffee equipment and install it on the brewing rack 7, detach the filter holder 2 and leave it in place, and place the coffee cup to the positioning position below the brewing rack 7.

Press the start button 64, all the load measurements and timings on the electronic scale 6 automatically return to zero, the automatic control system starts the electromagnetic valve 52 to discharge hot water, and the electronic scale 6 starts measuring and timing at the same time. When the hot water output reaches 50CC, the automatic control system closes the electromagnetic valve 52, and the timing device starts the electromagnetic valve 52 at the 40th second. When the hot water output reaches 130CC, the automatic control system closes the electromagnetic valve 52. The timing device starts the electromagnetic valve 52 at the 70th second. When the hot water output reaches 210CC, the automatic control system closes the electromagnetic valve 52, and the timing device At the 110th second, the automatic control system starts the electromagnetic valve 52.

The cold water inlet hole 202 is connected to the cold water outlet pipe 51b of the cold water insulation barrel 5b but they do not touch each other, so that the weighing of the electronic scale 6 is not interfered by the hot water insulation barrel 5a and the cold water insulation barrel 5b.

Execution procedure: In this embodiment, a suitable coffee bag is prepared in advance. A barcode is printed on the packaging bag of the coffee bag. The barcode content is the brewing procedure of the coffee powder. The automatic control system stores the coffee brewing procedure of each barcode. When the water storage tank 20 is in standby mode, there is no water stored. When brewing coffee, the barcode on the coffee bag is first scanned on the barcode scanner 8. After scanning, the electronic scale 6 counts seconds and the measurement is reset to zero. The automatic control system calculates the appropriate ratio according to the required brewing water volume, brewing temperature, hot water temperature of the hot water insulation bucket 5a and cold water temperature of the cold water insulation bucket 5b according to the barcode content, first opens the cold water solenoid valve 52b of the cold water insulation bucket 5b to output cold water, and closes the cold water solenoid valve 52b when the electronic scale 6 detects the appropriate amount of cold water, and then opens the hot water solenoid valve 52a of the hot water insulation bucket 5a. When the electronic scale 6 detects the appropriate amount of hot water, the hot water solenoid valve 52a is closed, and the hot water in the water storage tank 20 is mixed into the desired amount and temperature for standby use. The coffee bag is torn open and the coffee powder is poured into the filter paper 3 of the brewing device. After the water guide 4 is properly placed, the brewing device is positioned. The operation key is pressed, and the automatic control system opens and closes the brewing solenoid valve according to the established program of the number of coffee brewing stages, the water output of each stage and the brewing time. 30, the electronic scale 6 calculates the amount of water stored in the water tank 20 and the number of seconds. When the electronic scale 6 detects that the water storage tank 20 is zero at the last stage of hot water brewing, the brewing solenoid valve 30 is closed. When the total brewing time is reached, a sound or a light signal can be emitted to indicate that the coffee brewing process is completed. If the wash-free brewing mechanism of the present invention is used indoors, the barcode can also be directly generated by the ordering machine (POS machine).

In addition, the hand-infusing device of the present invention can be suspended and directly placed under the infusing device, and the infusing device (not shown) can output hot water to infuse beverage materials, and the flow meter of the infusing device can be used for metering. The present invention can also be used to infuse health tea (such as Chinese medicine). During the process of infusing beverage materials, the hand-infusing device will not touch the soup, and the tampering of taste can also be avoided.
