In this embodiment, when syrup needs to be added to coffee in the automatic coffee vending machine by the rotary type sugar adding device based on the pressing rod, the specific process is as follows:
1) when a user selects the type of syrup to be added in the automatic coffee vending machine, a driving signal is generated to drive the rotary disk driving motor 1004 to start so as to drive the quantitative bottle fixing frame 1005 arranged on the rotary disk 1003 to rotate until the quantitative bottle 1006 of the type of syrup selected by the user is positioned below the quantitative bottle pressing assembly 1008;
2) the quantitative bottle pressing component 1008 moves towards the direction close to the quantitative bottle 1006 under the action of the driving force, and firstly, the quantitative bottle pressing component 1008 is contacted with the top end of the rotary pressing component 10071 in the pressing lever component 1007 and then is pressed downwards continuously, so that the rotary pressing component 10071 drives the lever component 10072 to rotate, the lever component 10072 rotates to be contacted with the pump head 1006a and then rotates continuously until the pump head 1006a rotates to be in a pulling positive rotating state around the bottle opening of the quantitative bottle 1006;

In the process, the selection of the type of sugar in the quantitative bottle to be added (i.e. the selection of the type of sugar to be added) and the pressing-down sugar adding process can be triggered only by sequentially sending trigger signals to the rotary disk drive motor 1004 and the quantitative bottle pressing assembly 1008, and the manual sugar adding operation is not needed.
The sugaring apparatus body 1001 in fig. 1 is not shown in its entirety, but only shows a partial structure. The water tank 1002 is filled with insect repellent powder and mixed with water to form insect repellent liquid, so that insects which like saccharides enter the sugar adding device body 1001 and then enter the quantitative bottle 1006.
In an embodiment, as shown in fig. 2 and 3, the rotary pressing member 10071 includes:
a hold-down member securing sheet pack 100711 secured to the securing frame; wherein, the pressing member fixing sheet group 10071a includes an upper fixing sheet 100711a fixedly disposed on the fixing frame, and a lower fixing sheet 100711b fixedly disposed on the fixing frame and located below the upper fixing sheet 100711 a; a first fixing through groove 100711a1 is formed in the upper fixing plate, and a second fixing through groove 100711b1 is formed in the lower fixing plate 100711 b;
a hollow pressing member body 100712 having one end contacting the first fixing through groove 100711a1 and the other end contacting the second fixing through groove 100711b 1;
a built-up through slot 100713 provided on an outer wall of the hold-down member body 100712; the combined through grooves include a first spiral through groove 100713a and a second spiral through groove (not shown in the drawings due to the view angle), which are symmetrically arranged, a first straight through groove 100713b, the top end of which is integrally formed with the bottom end of the first spiral through groove 100713a, and a second straight through groove, the top end of which is integrally formed with the bottom end of the second spiral through groove (not shown in the drawings due to the view angle);
a combined push rod 100714 extending through the first fixed channel 100711a1, the hold down member body 100712, and the second fixed channel 100711b 1; wherein the combination depressible bar 100714 comprises an upper end depressible bar 100714a and a lower end depressible bar 100714b integrally formed with the upper end depressible bar 100714 a; a transverse pressure lever mounting channel 100714a1 is arranged on the upper end lower pressure lever 100714 a;
a transverse hold down bar 100715 extending through the transverse hold down bar mounting channel, the transverse hold down bar movable along the compound channel 100713;
and the compression spring 100716 is sleeved on the lower end lower pressure rod 100714 b.
In this embodiment, the top end of the compression spring 100716 is in contact with the bottom end of the lateral push rod 100715. When the top end of the upper end down lever 100714a of the combined down lever 100714 is pressed downward by the quantitative bottle down assembly 1008, the transverse down lever 100715 moves from top to bottom along the combined through slot 100713, and the compression spring 100716 continues to compress under the force of the transverse down lever 100715. Since the lateral lower pressing bar 100715 does not move along a straight through slot when moving along the combined through slot 100713 from top to bottom, the combined lower pressing bar 100714 is rotated by a certain angle when moving along the combined through slot 100713 shown in fig. 2. Since the lever unit 10072 is disposed at the bottom end of the rotary push-down component 10071 (more specifically, the lever unit 10072 is sleeved at the bottom end of the lower push-down rod 100714b in the combined push-down rod 100714), the lever unit 10072 is synchronously driven to rotate a certain angle when the lower push-down rod 100714b rotates a certain angle. At this time, if the lever member 10072 rotates by a certain angle and contacts the pump head 1006a, the pump head 1006a continues to rotate until the pump head 1006a rotates around the opening of the vial 1006 to the turning state. By providing the rotary pressing member 10071 having the above structure, the pressing force can be converted into the urging force for the pump head.

By providing the vertical lever 100722, it can move the pump head 1006a on the metered bottle 1006 when receiving the force from the arc-shaped tab 100721.
In one embodiment, as shown in fig. 1-4, the metered vial hold-down assembly 1008 comprises:

a pressing assembly 10084 having one end connected to the other end of the link assembly 10082 and penetrating the linear bearing 10083, wherein the pressing assembly 10084 is used for pressing and applying force.
In this embodiment, after the push down driving motor 10081 receives the trigger signal sent by the control chip (such as MCU control chip) of the automatic coffee vending machine, the driving shaft of the push down driving motor 10081 can be triggered to start rotating. At this time, the link assembly 10082 is driven by the push-down driving motor 10081 to drive the push-down assembly 10084 to move upward or downward, so as to realize the process of pushing down the pump head 1006a on the top end of the dosing bottle 1006 by the push-down assembly 10084 to pump out the syrup. The quantitative bottle pressing component 1008 with the structure can drive the pressing process of the pump head 1006a, so that automatic sugar adding of the sugar adding device is realized.

Since one end of the crank connecting rod 100822 (i.e., the lower end of the crank connecting rod 100822) is connected to the driving shaft connecting rod 100821, the driving shaft connecting rod 100821 drives the crank connecting rod 100822 to move together when rotating. The link assembly 10082 is effective to transmit the driving force of the link assembly 10082 to the lower pressure lever assembly 10034 to press down the pump head 1006 a. This link assembly 10082 need not to adopt rack and pinion mechanism that pushes down, and equipment structure is simple, and the cost is lower.
In an embodiment, as shown in fig. 1-4, the crank connecting rod 100822 comprises a first side crank portion 100822a and a second side crank portion 100822b, an upper end of the first side crank portion 100822a and an upper end of the second side crank portion 100822b are connected by an upper end pin 100822c, a lower end of the first side crank portion 100822a and a lower end of the second side crank portion 100822b are connected by a lower end pin 100822 d; the drive shaft connecting rod 100821 is sleeved on the upper end pin shaft 100822 c; one end of the pressing component 10084 is sleeved on the lower end pin 100822 d.

Preferably, the first side crank portion 100822a and the second side crank portion 100822b are both configured as an arc structure, rather than a linear structure, so as to effectively avoid the driving shaft connecting rod 100821 during the rotation process and increase the stroke of the pressing assembly 10084.
In one embodiment, as shown in fig. 1-4, the pressing assembly 10084 comprises:
one end of the pressure lever 100841 is sleeved on the lower end pin shaft 100822 d;

When the pressing rod 100841 moves downward from top to bottom, the second lower pressing block 10084 first touches the upper lower pressing rod 100714a, and in the process that the upper lower pressing rod 100714a is pressed downward, the lower pressing rod 100714b integrated with the upper lower pressing rod drives the arc-shaped connecting piece 100721 and the vertical shift lever 100722 to move, and at this time, the vertical shift lever 100722 firstly aligns the pump head 1006 a. The lower first pressing piece 100842 then touches the pump head 1006a, and then presses the pump head 1006a to pump out the syrup in the fixed-amount bottle 1006 with the downward movement of the first pressing piece 100842.

In this embodiment, in order to precisely control the stroke interval of the pressing assembly 10084, an upper limit photosensor 1008a1 and a lower limit photosensor 1008a2 corresponding to the limit sensing tab 100841a may be disposed at this time, and the upper limit photosensor 1008a1 is located above the lower limit photosensor 1008a 2.
When the position-limiting sensing tab 100841a moves to the upper position-limiting photosensor 1008a1 and is sensed by the upper position-limiting photosensor 1008a1, a trigger signal (e.g., denoted as a first trigger signal) is generated, so that the push-down driving motor 10081 stops rotating clockwise, and the push-down assembly 10084 is regarded as being stopped at its initial position.
When the limit sensor tab 100841a moves to the lower limit photosensor 1008a2 and is sensed by the lower limit photosensor 1008a2, another trigger signal (e.g., denoted as a second trigger signal) is generated, such that the push-down driving motor 10081 stops rotating counterclockwise, and after waiting for a period of time (e.g., 0.5 s), the push-down driving motor 10081 starts rotating clockwise until the push-down assembly 10084 moves to its initial position and stops.
In an embodiment, as shown in fig. 1 and 5, the fixed-amount bottle fixing frame 1005 comprises 3 fixing frames, which are respectively marked as a first fixing frame 10051, a second fixing frame 10052 and a third fixing frame 10053; wherein the first fixed frame 10051 houses a first quantitative bottle 1006b1 therein, the second fixed frame houses a second quantitative bottle 1006b2 therein, and the third fixed frame houses a third quantitative bottle 1006b3 therein.
In this embodiment, if the fixed bottle holder 1005 is configured to include 3 fixed bottles, which means that 3 fixed bottles can be placed, in practice, each fixed bottle contains syrup of one concentration or one type, so that a user can select at least one of 3 concentrations or 3 types of syrup to be added to coffee.
For example, sucrose syrup is contained in the first quantitative bottle 1006b1, maltose syrup is contained in the second quantitative bottle 1006b2, and fructose syrup is contained in the third quantitative bottle 1006b 3; or the first quantitative bottle 1006b1 contains low-concentration syrup (the glucose conversion value DE of the low-concentration syrup is below 20), the second quantitative bottle 1006b2 contains medium-concentration syrup (the glucose conversion value DE of the medium-concentration syrup is between 38 and 42), and the third quantitative bottle 1006b3 contains high-concentration syrup (the glucose conversion value DE of the high-concentration syrup is between 60 and 70). By setting multiple concentrations or types of syrup, multiple sugar adding choices are provided for users.
In an embodiment, as shown in fig. 1 and fig. 6, an inner ring induction sheet set and an outer ring induction sheet set are circumferentially arranged on a lower end surface of the water tank 1002; the sugar adding device body 1001 is provided with an inner ring photoelectric sensor 100231 corresponding to the inner ring induction sheet set, and an outer ring photoelectric sensor 100232 corresponding to the outer ring induction sheet set.

In this embodiment, when the fixed amount bottle fixing frame 1005 is configured to include 3 fixing frames, in order to position the current rotation stop position of the fixed amount bottle fixing frame 1005, 1 inner ring sensing piece may be provided. Specifically, when the first inner ring sensing tab 100221 moves to align with the inner ring photosensor 100231 (i.e., the first inner ring sensing tab 100221 is sensed by the inner ring photosensor 100231), it corresponds to the origin position of the quantitative bottle fixing frame 1005.
When any one of the first outer ring sensing piece 100211, the second outer ring sensing piece 100212 and the third outer ring sensing piece 100213 is sensed by the outer ring photoelectric sensor 100232, it indicates that one of the 3 quantitative bottles is located at the sugar adding position, and the pump head of the quantitative bottle is aligned with the cup body placed below the quantitative bottle. It can be seen that by arranging the inner ring sensing plate group and the corresponding inner ring photoelectric sensor 100231, and by arranging the outer ring sensing plate group and the corresponding outer ring photoelectric sensor 100232, the current rotation stop position of the quantitative bottle fixing frame 1005 can be accurately detected, and the quantitative bottle fixing frame 1005 can be conveniently controlled to select one of the quantitative bottles for adding sugar.

A2) then the rotary disk driving motor 1004 stops driving the fixed amount bottle fixing frame 1005 to rotate, at this time, the downward driving motor 10081 drives the first downward pressing block 100842 and the second downward pressing block 100843 in the downward pressing assembly 10084 to move towards the direction close to the fixed amount bottle 1006, firstly, the second downward pressing block 100843 is pressed downwards continuously after contacting with the top end of the downward pressing part 10071 in the downward pressing lever assembly 1007, so that the downward pressing part 10071 drives the lever part 10072 to rotate, the lever part 10072 rotates to contact with the pump head 1006a to stir the pump head 1006a to rotate continuously until the pump head 1006a rotates to the pulling positive rotation state around the mouth of the fixed amount bottle 1006 (the pump head of the third fixed amount bottle 1006b3 is pulled positive to be understood as the axial line of the pump head 1006a, the pump head 1006a continues to be pressed downwards by the first downward pressing block 100842 to pump syrup, the syrup falls into the cup placed below the fixed amount bottle 1006a, the syrup adding process is realized
A3) After the sugar adding process is completed, the turntable driving motor 1004 is controlled to rotate clockwise by a first angle (e.g., the second angle is 30-60 °), and at this time, the pump head of the third quantitative bottle 1006b3 touches the vertical stop 1009, so that the pump head of the third quantitative bottle 1006b3 returns to the original state.
The above describes the rotational positioning process of the fixed bottle holder 1005 by taking the movement positioning process of the third fixed bottle 1006b3 as an example, and in the specific implementation, the movement positioning process of the third fixed bottle 1006b3 can be referred to the movement positioning process of the first fixed bottle 1006b1 and the second fixed bottle 1006b 2.
