Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid dispensing device capable of dispensing liquids such as Western liquors, wine, cocktails, syrups, soy sauce, etc. either in quantitative or desired amounts.

[Prior Art] Generally, a liquid dispensing device is sometimes used in a bar or the like to provide whiskey, brandy, spritzes, beer, etc. to customers.

Most of the conventionally provided liquid dispensing devices have a tube with a cap that is directly connected to the mouth of a Western liquor barrel or bottle, and because the internal pressure of draft beer barrels is high, a special tube with a cap is used. , this tube with a pot has a valve seat at the spout at the end of the tube that constitutes the valve chamber,
It is known that the valve seat is provided with a valve body that is seated or separated by the movement of the valve stem by the tilting of the handle. According to this conventional example, by tilting the handle for a desired period of time and separating the valve body from the valve seat, a desired amount of Western liquor, etc. could be flowed out from the spout.

[Problems to be solved by the invention] However, according to the above-mentioned conventional example, the desired amount of Western liquor, etc. flows out by continuing to tilt the handle for a desired period of time, so the intuition of the person who should operate the handle is difficult. The flow rate must be determined based on skill and skill, and it is extremely difficult to uniformly flow out a fixed amount each time it is needed. Therefore, for example, when Western liquor is served in single, jigger, or double portions, the amount must vary.

[Means for Solving the Problems] In order to solve the above problems, the present invention has a main body provided with a valve chamber communicating with a liquid supply source, and is swingably mounted on the outside of the main body. In the liquid dispensing device, the liquid flows out from the spout by tilting the handle to separate the valve body from the valve seat, and the valve chamber includes a metering space and a metering space capable of storing a predetermined amount of liquid. forming a capacity adjustment part and providing air bleed means; the handle is provided with a cam that can be tilted in two successive steps in one direction;
One end of a first valve stem is rotatably connected to the cam, a recess is formed in the first valve stem, and a second valve has a protrusion at one end that can be engaged with and detached from the recess. A rod is provided with an elastic body interposed therebetween so that the rod can be moved in orthogonal directions, and the other end of the second valve rod has a valve that can be engaged with and detached from a valve seat formed between the valve chamber and a liquid supply pipe connected to the valve chamber. When the handle is moved to the first stage of the cam, the first
As the valve element of the second valve stem moves away from the valve seat, the protrusion of the second valve stem enters the recess of the first valve stem and the valve element of the second valve stem comes into contact with the valve seat, thereby closing the valve. A predetermined amount of liquid stored in the chamber can be poured out, and the valve bodies of the first valve stem and second valve stem are both moved away from their respective valve seats to pour out the desired amount of liquid. To provide a liquid dispensing device capable of dispensing liquid.

[Operation] According to the present invention, when the handle is first tilted one step, the valve body separates from the valve seat and the spout is opened, and the movement of the valve stem causes the protrusion of the second valve stem to move toward the first The valve element is seated on the valve seat of the liquid supply pipe to close the liquid flow path, and atmospheric air flows into the valve chamber from the air vent pipe and causes a constant amount of air to be stored in the valve chamber. Allow a certain amount of liquid to flow out of the spout. On the other hand, when the handle is tilted one more step from this state, the first valve stem moves further upwards than above, the protrusion that engages with the recess is detached, and the valve body of the second valve stem becomes liquid. The liquid flow path is opened by moving away from the valve seat of the supply pipe, and the liquid continuously flows out from the spout, allowing the desired amount of liquid to be poured out. Then, when the handle is returned to its original state, the first valve stem moves in the opposite direction to the above, and the protrusion of the second valve stem temporarily engages with the recess;
The protrusion comes out of the recess again, and the valve body of the first valve stem closes the spout, and the valve body of the second valve stem moves away from the valve seat of the liquid supply pipe, causing the liquid to flow into the valve chamber. It is eggplant.

The liquid storage container 114 has a cap 113 inserted into a receiver 111 and is erected upside down.

Next, to explain the operation of the above embodiment, in the state shown by the solid line in FIG.
1, the spout 6 is closed, and the liquid flows into the main body 1.
Do not leak outside. Therefore, the cam surface 41 of the cam 4 is in contact with the contact plate 14, and the handle 3 extends substantially coaxially with the valve stem 5. On the other hand, the protrusion 71 of the second valve stem 7 contacts the upper side of the recess 58 , and the valve body 72 separates from the valve seat 16 against the biasing force of the coil spring 17 . The liquid supply pipe 10 and the liquid supply pipe 10 are connected as a series, and the liquid falling into the receiver 111 flows into the valve chamber 2. Therefore, in order to dispense a fixed amount of liquid, first, rotate the handle 3 to the left in the figure around the shaft 44, and rotate the handle 3 at an angle of approximately 45 degrees so that the cam surface 42 of the cam 4 contacts the contact plate 14. Tilt. Then, the valve stem 5 moves upward by the height difference (ba) between the cam surfaces 41 and 42. This amount of movement is determined by the recess 58 of the valve stem 5.
is a length that can face the protrusion 71 of the second valve stem 7. Then, when the recess 58 and the protrusion 71 face each other,
The second valve rod 7 moves to the left in the drawing due to the biasing force of the coil spring 17, and the valve body 72 contacts the valve seat 16 to close the liquid supply path. On the other hand, when the valve stem 5 moves upward, the valve body 56 moves toward the valve seat 2 of the spout 6.
1, but remains seated by the force of the coil spring 55, and only when the valve body 72 is seated on the valve seat 16 does the valve body 56 move to the valve seat 2.
1 and the liquid flows out from the spout 6.

Next, when the handle 3 is further tilted in the same direction as above and the cam surface 43 of the cam 4 and the contact plate 14 are brought into contact, the valve stem 5 is
-b) move further upwards. Therefore, the protrusion 71 of the second valve stem 7 that was engaged with the recess 58 of the valve stem 5 escapes from the recess 58 again. When the protrusion 71 escapes from the recess 58, the second valve stem 7 moves to the right in the figure, causing the valve body 72 to move away from the valve seat 16, except for the protrusion 71 coming into contact with the valve stem 5 on the lower side of the recess 58. The state is again shown by the solid line in FIG. Therefore, the valve chamber 2 communicates with the liquid supply pipe 10 and liquid flows into the valve chamber 2, and since the spout 6 is still open, the liquid continues to flow until the spout 6 is closed. leak.

To close the spout 6, the handle 3 can be returned to its original state as shown by the solid line in FIG. When the handle 3 is raised, the cam surface 41 of the cam 4
is in contact with the contact plate 14, and the orthogonal distance a between the shaft 44 and the cam surface 41 is minimized, so the valve rod 5 is moved downward in the figure by the force of the coil spring 50, and the valve body 5
6 is seated on the valve seat 21 to close the spout 6.

2 to 4 show other embodiments having the same basic configuration as the above embodiment, and the same reference numerals indicate the same or corresponding parts.

In the embodiment shown in FIG. 2, in order to increase the volume of the metering space formed by the valve chamber 2 compared to that of the embodiment shown in FIG. An extension tube 21 is provided. Reference numeral 22 denotes a stopper that is screwed onto the end of the extension tube 21 to finely adjust the capacity of the valve chamber extension 20.

The embodiment shown in FIG. 3 is similar to the embodiment shown in FIG. It will be done. This auxiliary tank part 23
The container is, for example, in the shape of a closed can, with a through hole 24 bored in the bottom that opens into the valve chamber 2, and a second air vent pipe 25 is connected to the top of the container. The air bleed pipe 25 and the air bleed pipe 9 communicating with the valve chamber 2 are provided with cock valves 26 and 27, respectively, and operating rods 28 and 29 for opening and closing these valves 26 and 27, as well as these operating rods. A switching lever 30 for switching between 28 and 29 is fixed to a fixed part 8 on the handle 3 side. In addition, the auxiliary tank part 23
has a required volume to accommodate the required amount of liquid, and is provided to protrude upward from the main body 1, and the liquid flowing into the valve chamber 2 is contained in the auxiliary tank portion 23 through a through hole 24.
In order to be able to flow in through the liquid supply source 11, it is necessary that the liquid level WL of the receiver 111 in the liquid supply source 11 exists at approximately the same level as the upper part of the auxiliary tank part 23 or at a higher height. The side walls are high and the bottom is deep. In this embodiment, in order to pour out the liquid stored only in the valve chamber 2, the switching lever 30 is operated to open the cock valve 27 of the air vent pipe 9, allowing atmospheric air to flow into the valve chamber 2. Then, as in the case of the previous embodiment, the handle 3 is tilted at about 45 degrees to bring the cam surface 42 and the contact plate 14 into contact. Valve stem 5 due to this operation
After the valve body 72 of the second valve stem 7 is seated on the valve seat 16 by this movement, the valve body 56 opens the spout 6. Therefore, only the liquid within the valve chamber 2 flows out from the spout 6. That is, the air vent pipe 25 of the auxiliary tank section 23 is not pushed out by atmospheric pressure because the cock valve 26 is closed and not opened.
Only the liquid in the valve chamber 2, which is open to the atmosphere, flows out. On the other hand, in order to pour out the liquid stored in both the valve chamber 2 and the auxiliary tank section 23, operate the switching lever 30 to release the liquid stored in both the valve chamber 2 and the auxiliary tank section 23.
open. Then, the liquid level in the auxiliary tank section 23 located above the valve chamber 2 is pushed by atmospheric pressure, so if the handle 3 is tilted approximately 45 degrees in the same manner as described above, the liquid level in the auxiliary tank section 23 located above the valve chamber 2 is pushed through the spout 6 through the valve chamber 2 and the auxiliary tank. The liquid in the portion 23 flows out. Then, when the handle 3 is returned to its original state, the cam surface 41 and the contact plate 14 are brought into contact, and the cock valve 26 of the air vent pipe 25 is opened, the first valve stem 5 moves downward in the figure. Valve body 5
6 seats on the valve seat 21 to close the spout 6, and the valve body 72 of the second valve stem 7 separates from the valve seat 16 to open the liquid flow path, so that the liquid in the receiver 111 reaches atmospheric pressure. The liquid is pushed and flows through the liquid supply pipe 10 into the valve chamber 2 and the auxiliary tank section 23. In addition, the auxiliary tank part 2
3 may be plural.

Another embodiment shown in FIG. 4 is one in which a valve stem 5 is provided with a structure in place of the air bleed pipe 9 of the valve chamber 2. That is, a valve chamber 120 is provided at the upper end of the valve stem 5, and a ball valve 122 and a valve chamber 1 that move toward and away from the valve seat 121 are provided at the upper end of the valve stem 5.
The valve chamber 120 is housed in the valve chamber 20, and a through hole 123 is formed to allow the valve chamber 120 and the valve chamber 2 to communicate with each other. Ball valve 122 consists of a plastic ball.

Therefore, in this example, when the pressure of the liquid flowing into the valve chamber 2 is high, the ball valve 122 is seated on the valve seat 123, and when the valve body 72 of the second valve stem 7 is seated on the valve seat 16, the ball valve 122 is seated on the valve seat 123. is separated from the valve seat 123, and when the handle 3 is tilted in this state, the atmosphere flows into the valve chamber 120 and the through hole 123, and the liquid in the valve chamber 2 flows out from the spout 6.

[Effects of the invention] According to the invention described above, a predetermined amount of liquid can be dispensed by tilting the handle one step, and
Since the desired amount of liquid can be dispensed by tilting in two stages, two types of liquid dispensing operations, quantitative or continuous, are possible with a single handle. Therefore, it is possible to avoid dispensing a fixed amount of liquid based on human intuition and skill as in the past, and it is possible to always dispense a uniform amount of fixed amount of liquid. In addition, the handle can be tilted in one step to switch between quantitative and continuous liquid dispensing, and a first valve stem that is moved by the handle and a second valve stem that engages and disengages are provided. Since the structure is such that the liquid supply to the valve chamber is interrupted, the entire device can be made compact and can be formed with a simple appearance. Furthermore, when dispensing a fixed amount of liquid, the amount can be increased by expanding the capacity of the valve chamber or by providing an auxiliary tank or a volume fine adjustment section.
Jigger or double metering settings can also be determined in advance by selecting the liquid dispensing device. Furthermore, since the liquid supply source can be provided at a location away from the main body, it is possible to provide effects such as being able to install it at a location that is not visible from the outside and improving the appearance.
