Figure 1-Figure 6 As shown, the rotary sugaring device 1000 based on the downward pressing lever includes:

[0026] Sugar adding device body 1001;

[0027] A water tank 1002 disposed in the sugaring device body 1001;

[0028] A rotating disk 1003 disposed on the upper end surface of the water tank 1002;

[0029] A rotating disk driving motor 1004 is disposed on the sugar adding device body 1001 and is located below the water tank 1002, and the rotating disk 1003 is sleeved on the driving shaft of the rotating disk driving motor 1004;

[0030] A quantitative bottle fixing frame 1005 disposed on the upper end surface of the rotating disk 1003, wherein the quantitative bottle fixing frame 1005 includes a plurality of fixing frames disposed around the upper end surface of the rotating disk;

[0031] A corresponding number of quantitative bottles 1006 are arranged in a plurality of fixed frames, and the quantitative bottles 1006 contain syrup; wherein a pump head 1006a is arranged on the bottle mouth of each quantitative bottle, and the pump head 1006a can rotate around the bottle mouth of the quantitative bottle 1006;

[0032] A downward pressing lever assembly 1007 is arranged on each fixed frame, and the downward pressing lever assembly 1007 includes a rotating downward pressing component 10071 and a lever component 10072 arranged at the bottom end of the rotating downward pressing component 10071. When the rotating downward pressing component 10071 is subjected to downward pressure, it drives the lever component 10072 to rotate so as to drive the pump head 1006a to rotate around the bottle mouth of the quantitative bottle 1006;

[0033] A quantitative bottle pressing assembly 1008 disposed in the sugar adding device body 1001 and located above the quantitative bottle fixing frame, and used to apply force to the pump head 1006a and the pressing lever assembly 1007;

[0034] A vertical blocking column 1009 is fixedly disposed in the sugar adding device body 1001 and is located on one side of the quantitative bottle pressing assembly 1008 .

[0035] In this embodiment, when it is necessary to add syrup to the coffee in the automatic coffee vending machine through the rotary sugar adding device based on the downward pressing lever, the specific process is as follows:

[0036] 1) When the user selects the type of syrup to be added in the automatic coffee vending machine, a driving signal is generated to drive the rotating disk driving motor 1004 to start, so as to drive the quantitative bottle fixing frame 1005 set on the rotating disk 1003 to rotate until the quantitative bottle 1006 of the type of syrup selected by the user is located below the quantitative bottle pressing assembly 1008;

[0037] 2) The quantitative bottle pressing component 1008 moves towards the direction close to the quantitative bottle 1006 under the action of the driving force, first contacts the top of the rotating pressing component 10071 in the pressing lever component 1007 and then continues to press down, so that the rotating pressing component 10071 drives the lever component 10072 to rotate, and the lever component 10072 rotates until it contacts the pump head 1006a and then continues to rotate until the pump head 1006a rotates around the bottle mouth of the quantitative bottle 1006 to the straightening state;

[0038] 3) Then, the quantitative bottle pressing component 1008 continues to move downward under the driving force until it contacts the pump head 1006a and presses down to pump out the syrup, and the syrup falls into the cup body placed below the pump head 1006a, completing the process of adding syrup.

[0039] During this process, it is only necessary to send trigger signals to the rotating disk drive motor 1004 and the quantitative bottle pressing component 1008 in sequence to trigger the process of selecting which quantitative bottle of sugar to add (that is, selecting the type of sugar to add) and pressing down to add sugar, without the need for manual operation to add sugar.

[0040] in, Figure 1 The sugaring device body 1001 is not fully shown, only the partial structure is shown. The water tank 1002 is filled with insect repellent powder and mixed with water to form an insect repellent solution to prevent insects that like sugar from entering the sugaring device body 1001 and then entering the quantitative bottle 1006.

[0041] In one embodiment, if Figure 2 and Figure 3 As shown, the rotating pressing component 10071 includes:

[0042] A pressing component fixing plate group 100711 fixed on the fixing frame; wherein the pressing component fixing plate group 10071a comprises an upper fixing plate 100711a fixedly arranged on the fixing frame, and a lower fixing plate 100711b fixedly arranged on the fixing frame and located below the upper fixing plate 100711a; the upper fixing plate is provided with a first fixing through groove 100711a1, and the lower fixing plate 100711b is provided with a second fixing through groove 100711b1;

[0043] A hollow pressing component body 100712, one end of which contacts the first fixing groove 100711a1 and the other end of which contacts the second fixing groove 100711b1;

[0044] A combined through groove 100713 is arranged on the outer wall of the pressing component body 100712; wherein the combined through groove includes a first spiral through groove 100713a and a second spiral through groove (not shown in the figure due to viewing angle problems) that are symmetrically arranged, a first linear through groove 100713b whose top end is integrally formed with the bottom end of the first spiral through groove 100713a, and a second linear through groove whose top end is integrally formed with the bottom end of the second spiral through groove (not shown in the figure due to viewing angle problems);

[0045] A combined pressing rod 100714 that penetrates the first fixed through slot 100711a1, the pressing component body 100712, and the second fixed through slot 100711b1; wherein the combined pressing rod 100714 comprises an upper pressing rod 100714a and a lower pressing rod 100714b that is integrally formed with the upper pressing rod 100714a; and a transverse pressing rod installation channel 100714a1 is provided on the upper pressing rod 100714a;

[0046] A transverse pressing rod 100715 passing through the transverse pressing rod installation channel, wherein the transverse pressing rod can move along the combined through slot 100713;

[0047] A compression spring 100716 is sleeved on the lower end pressure rod 100714b.

[0048] In this embodiment, the top end of the compression spring 100716 contacts the bottom end of the lateral downward pressing rod 100715. When the top end of the upper downward pressing rod 100714a in the combined downward pressing rod 100714 is subjected to downward pressure from the quantitative bottle downward pressing assembly 1008, the lateral downward pressing rod 100715 moves from top to bottom along the combined through slot 100713. At this time, the compression spring 100716 continues to be compressed under the action of the lateral downward pressing rod 100715. Since the lateral downward pressing rod 100715 does not move along the linear through slot when moving from top to bottom along the combined through slot 100713, it moves along the linear through slot as shown in FIG. Figure 2When the combined through slot 100713 shown moves, it will drive the combined push rod 100714 to rotate a certain angle. Since the lever component 10072 is arranged at the bottom end of the rotating push rod 10071 (more specifically, the lever component 10072 is sleeved on the bottom end of the lower push rod 100714b in the combined push rod 100714), when the lower push rod 100714b rotates a certain angle, it will synchronously drive the lever component 10072 to rotate a certain angle. At this time, if the lever component 10072 contacts the pump head 1006a during the rotation of a certain angle, it will continue to rotate until the pump head 1006a rotates around the bottle mouth of the quantitative bottle 1006 to the straightening state. By setting the rotating push rod 10071 with the above structure, the downward force can be converted into a driving force on the pump head after the force direction is converted.

[0049] In one embodiment, if Figure 2 and Figure 3 As shown, the lever component 10072 includes:

[0050] An arc-shaped connecting piece 100721 ​​having one end sleeved on the bottom end of the lower end pressing rod 100714b and located below the lower fixing piece 100711b;

[0051] A vertical lever 100722 is vertically arranged on the upper end surface of the arc-shaped connecting piece 100721 ​​and is located on the other end of the arc-shaped connecting piece 100721 ​​away from the lower end pressing rod 100714b.

[0052] In this embodiment, the arc-shaped connecting piece 100721 ​​is provided to extend the arm length of the combined pressing rod 100714 so that when the combined pressing rod 100714 rotates under the downward pressure, the force is transmitted to a position at a distance (e.g., 1-10 cm) from the combined pressing rod 100714. By providing a vertical lever 100722, when it receives the force transmitted by the arc-shaped connecting piece 100721, the pump head 1006a on the quantitative bottle 1006 can be moved.

[0053] In one embodiment, if Figure 1-Figure 4 As shown, the quantitative bottle pressing assembly 1008 includes:

[0054] A pressing assembly frame 1008a provided on the sugaring device body 1001;

[0055] A downward pressing driving motor 10081 disposed on the downward pressing component frame 1008a;

[0056] A connecting rod assembly 10082 having one end connected to the driving shaft of the downward pressure driving motor 10081;

[0057] A linear bearing 10083 fixedly disposed on the downward pressing assembly frame 1008a and located below the connecting rod assembly 10082;

[0058] A pressing component 10084 , one end of which is connected to the other end of the connecting rod component 10082 and passes through the linear bearing 10083 , is used for applying downward pressure.

[0059] In this embodiment, when the downward pressure driving motor 10081 receives a trigger signal sent by the control chip (such as MCU control chip) of the automatic coffee vending machine, the driving shaft of the downward pressure driving motor 10081 can be triggered to start rotating. At this time, the connecting rod assembly 10082 starts to drive the downward pressure assembly 10084 to move upward or downward under the drive of the downward pressure driving motor 10081, thereby realizing the process of the downward pressure assembly 10084 pressing down the pump head 1006a on the top of the quantitative bottle 1006 to pump out the syrup. The quantitative bottle downward pressure assembly 1008 with the above structure can drive the downward pressure process of the pump head 1006a, thereby realizing the automatic sugaring of the sugaring device.

[0060] In one embodiment, if Figure 1-Figure 4 As shown, the connecting rod assembly 10082 includes:

[0061] A drive shaft connecting rod 100821 having one end connected to the drive shaft of the downward pressure drive motor 10081;

[0062] A crank connecting rod 100822, one end of which is connected to the driving shaft connecting rod 100821 and the other end of which is connected to the pressing assembly 10084.

[0063] In the present embodiment, one end of the driving shaft connecting rod 100821 is sleeved on the driving shaft of the downward pressing driving motor 10081, and when the driving shaft of the downward pressing driving motor 10081 rotates, the driving shaft connecting rod 100821 rotates synchronously. 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, when the driving shaft connecting rod 100821 rotates, it also drives the crank connecting rod 100822 to move together. Through the connecting rod assembly 10082, the driving force of the connecting rod assembly 10082 can be effectively transmitted to the downward pressing rod assembly 10034 to realize the downward pressing of the pump head 1006a. The connecting rod assembly 10082 does not need to adopt a gear rack downward pressing mechanism, and the equipment structure is simple and the cost is low.

[0064] In one embodiment, if Figure 1-Figure 4As shown, the crank connecting rod 100822 includes a first side crank portion 100822a and a second side crank portion 100822b, the upper end of the first side crank portion 100822a and the upper end of the second side crank portion 100822b are connected via an upper end pin 100822c, and the lower end of the first side crank portion 100822a and the lower end of the second side crank portion 100822b are connected via a lower end pin 100822d; wherein, the drive shaft connecting rod 100821 is sleeved on the upper end pin 100822c; and one end of the pressing assembly 10084 is sleeved on the lower end pin 100822d.

[0065] In this embodiment, an upper pin shaft 100822c is provided on the crank connecting rod 100822 to facilitate connection with the drive shaft connecting rod 100821, and a lower pin shaft 100822d is provided to facilitate connection with the pressing assembly 10084.

[0066] Preferably, the first side crank portion 100822a and the second side crank portion 100822b are both configured as arc structures rather than linear structures, in order to effectively avoid the drive shaft connecting rod 100821 during rotation and increase the stroke of the downward pressure assembly 10084.

[0067] In one embodiment, if Figure 1-Figure 4 As shown, the pressing assembly 10084 includes:

[0068] A pressure rod 100841 with one end sleeved on the lower end pin 100822d;

[0069] A first pressing block 100842 connected to the other end of the pressing rod 100841, wherein the first pressing block 100842 is located above the pump head 1006a;

[0070] A second pressing block 100843 connected to the first pressing block 100842, wherein the second pressing block 100843 is located above the rotating pressing component 10071; wherein the distance between the first pressing block 100842 and the pump head 1006a when in the initial position is recorded as a first distance, and the distance between the second pressing block 100843 and the upper end pressing rod 100714a when in the initial position is recorded as a second distance, and the second distance is smaller than the first distance.

[0071] In this embodiment, the pressure rod 100841 preferably penetrates the linear bearing 10083, and the top end of the pressure rod 100841 is sleeved on the lower end pin 100822d (that is, the top end of the pressure rod 100841 is provided with a connecting rod through-channel adapted to the lower end pin 100822d, and the lower end pin 100822d penetrates through the connecting rod through-channel). When the pressure rod 100841 moves downward from top to bottom, the second lower pressing block 10084 first touches the upper lower pressure rod 100714a, and at this time, during the process of the upper lower pressure rod 100714a being pressed down again, the lower lower pressure rod 100714b integrally provided therewith drives the arc-shaped connecting piece 100721 ​​and the vertical lever 100722 to move, and at this time, the vertical lever 100722 first straightens the pump head 1006a. Then, the first pressing block 100842 touches the pump head 1006a again, and then as the first pressing block 100842 continues to move downward, it presses the pump head 1006a to pump out the syrup in the metering bottle 1006.

[0072] In one embodiment, if Figure 1-Figure 4 As shown, a limit sensing plate 100841a is also provided on the pressure rod 100841; the cover pressing device frame 1008a is also provided with an upper limit photoelectric sensor 1008a1 and a lower limit photoelectric sensor 1008a2, and the travel range of the limit sensing plate 100841a is located between the upper limit photoelectric sensor 1008a1 and the lower limit photoelectric sensor 1008a2.

[0073] In this embodiment, in order to accurately control the travel range of the downward pressure component 10084, an upper limit photoelectric sensor 1008a1 and a lower limit photoelectric sensor 1008a2 corresponding to the limit sensing plate 100841a can be set, and the upper limit photoelectric sensor 1008a1 is located above the lower limit photoelectric sensor 1008a2.

[0074] When the limit sensing plate 100841a moves to the upper limit photoelectric sensor 1008a1 and is sensed by the upper limit photoelectric sensor 1008a1, a trigger signal (for example, recorded as the first trigger signal) is generated, causing the downward pressure drive motor 10081 to stop rotating clockwise. At this time, the downward pressure component 10084 is considered to have stopped at its initial position.

[0075] When the limit sensing plate 100841a moves to the lower limit photoelectric sensor 1008a2 and is sensed by the lower limit photoelectric sensor 1008a2, another trigger signal (for example, recorded as the second trigger signal) is generated, causing the downward pressure drive motor 10081 to stop rotating counterclockwise. After a delay of a period of time (such as 0.5s), the downward pressure drive motor 10081 starts to rotate clockwise until the downward pressure component 10084 moves to its initial position and stops.

[0076] In one embodiment, if Figure 1 and Figure 5 As shown, the quantitative bottle fixing frame 1005 includes three surrounding fixing frames, which are respectively denoted as the first fixing frame 10051, the second fixing frame 10052 and the third fixing frame 10053; wherein the first quantitative bottle 1006b1 is placed in the first fixing frame 10051, the second quantitative bottle 1006b2 is placed in the second fixing frame, and the third quantitative bottle 1006b3 is placed in the third fixing frame.

[0077] In this embodiment, if the quantitative bottle fixing frame 1005 is set to include 3 fixing frames, it means that 3 quantitative bottles can be placed. In specific implementation, a concentration or a type of syrup is placed in each quantitative bottle, so that the user can at least choose one of the 3 concentrations or 3 types of syrup to add to the coffee.

[0078] For example, the first quantitative bottle 1006b1 contains sucrose syrup, the second quantitative bottle 1006b2 contains maltose syrup, and the third quantitative bottle 1006b3 contains fructose syrup; or the first quantitative bottle 1006b1 contains low-concentration syrup (with a glucose conversion value DE below 20), the second quantitative bottle 1006b2 contains medium-concentration syrup (with a glucose conversion value DE between 38 and 42), and the third quantitative bottle 1006b3 contains high-concentration syrup (with a glucose conversion value DE between 60 and 70). By setting multiple concentrations or types of syrups, users are provided with more diverse sugaring options.

[0079] In one embodiment, if Figure 1 and Figure 6 As shown, the lower end surface of the water tank 1002 is provided with an inner circle sensor sheet group and an outer circle sensor sheet group arranged in a surrounding manner; the sugar adding device body 1001 is provided with an inner circle photoelectric sensor 100231 corresponding to the inner circle sensor sheet group, and an outer circle photoelectric sensor 100232 corresponding to the outer circle sensor sheet group.

[0080] In a specific implementation, the outer ring induction sheet group includes three outer ring induction sheets, which are respectively recorded as a first outer ring induction sheet 100211, a second outer ring induction sheet 100212 and a third outer ring induction sheet 100213;

[0081] The inner ring induction plate group includes one inner ring induction plate, which is recorded as the first inner ring induction plate 100221;

[0082] The distance between each inner ring sensor sheet in the inner ring sensor sheet group and the center of the water tank 1002 is smaller than the distance between each outer ring sensor sheet in the outer ring sensor sheet group and the center of the water tank 1002.

[0083] In this embodiment, when the quantitative bottle fixing frame 1005 is configured to include three fixing frames, an inner ring sensor sheet may be provided at this time in order to locate the current rotation stop position of the quantitative bottle fixing frame 1005. Specifically, when the first inner ring sensor sheet 100221 moves to align with the inner ring photoelectric sensor 100231 (i.e., the first inner ring sensor sheet 100221 is sensed by the inner ring photoelectric sensor 100231), this corresponds to the origin position of the quantitative bottle fixing frame 1005.

[0084] When any one of the first outer ring sensing sheet 100211, the second outer ring sensing sheet 100212, and the third outer ring sensing sheet 100213 is sensed by the outer ring photoelectric sensor 100232, it means that one of the three quantitative bottles is at the sugar adding position, and the pump head of the quantitative bottle is aimed at the cup body placed below it. It can be seen that by setting the inner ring sensing sheet group and the corresponding inner ring photoelectric sensor 100231, and setting the outer ring sensing sheet 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, so as to facilitate the control of selecting one of the quantitative bottles for sugar adding.

[0085] At this time, in order to understand the sugar adding process more clearly, the following Figure 1-Figure 6 The initial state of the pump head on the first quantitative bottle 1006b1, the pump head on the second quantitative bottle 1006b2 and the pump head on the third quantitative bottle 1006b3 is that the pump head is closer to the top center of the quantitative bottle fixing frame 1005 (see Figure 5In the state, if a circle is made with the top center of the quantitative bottle fixing frame 1005 and the line connecting the top center and the innermost end point of any pump head as the radius, the axis of the pump head on the first quantitative bottle 1006b1, the axis of the pump head on the second quantitative bottle 1006b2, and the axis of the pump head on the third quantitative bottle 1006b3 are all circumscribed with the circle, that is, the axis of the pump head on the first quantitative bottle 1006b1, the axis of the pump head on the second quantitative bottle 1006b2, and the axis of the pump head on the third quantitative bottle 1006b3 are all perpendicular to the radial direction of the circle). Afterwards, when the third quantitative bottle 1006b3 moves to the sugar adding position, the specific process is as follows:

[0086] A1) When the quantitative bottle fixing frame 1005 rotates clockwise under the driving force, the pump head of the third quantitative bottle 1006b3 first moves to the bottom of the first pressing block 100842, and the rotating pressing component 10071 in the pressing lever assembly 1007 on one side of the third quantitative bottle 1006b3 also moves to the bottom of the second pressing block 100843, and the outer ring induction sheet correspondingly arranged below the third quantitative bottle 1006b3 is aligned with the outer ring photoelectric sensor 100232 (indicating that the third quantitative bottle 1006b3 has moved to the sugar adding position at this time);

[0087] A2) After that, the rotating disk driving motor 1004 stops driving the quantitative bottle fixing frame 1005 to rotate, and at this time, the first pressing block 100842 and the second pressing block 100843 in the pressing assembly 10084 are driven by the pressing driving motor 10081 to move toward the direction close to the quantitative bottle 1006. First, the second pressing block 100843 contacts the top of the rotating pressing component 10071 in the pressing lever assembly 1007 and then continues to press down, so that the rotating pressing component 10071 drives the lever component 10072 to rotate. After the lever component 10072 rotates to contact the pump head 1006a, it drives the pump head 1006a to continue rotating until the pump head 1006a rotates around the bottle mouth of the quantitative bottle 1006 to the straightened state (the pump head of the third quantitative bottle 1006b3 being straightened can be understood as the axis of the pump head 1006a being parallel to the radial direction of the above-mentioned assumed circle). At this time, the pump head 1006a is further pressed down by the first pressing block 100842 to pump out the syrup, and the syrup falls into the cup body placed below the pump head 1006a, completing the process of adding syrup.

[0088] A3) After the sugar adding process is completed, the turntable drive motor 1004 is controlled to rotate clockwise by a first angle (such as the second angle is 30-60°). At this time, the pump head of the third quantitative bottle 1006b3 will touch the vertical stop column 1009, so that the pump head of the third quantitative bottle 1006b3 returns to its initial state.

[0089] The above takes the movement and positioning process of the third quantitative bottle 1006b3 as an example to illustrate the rotation and positioning process of the quantitative bottle fixing frame 1005. In specific implementation, the movement process of the first quantitative bottle 1006b1 and the second quantitative bottle 1006b2 can refer to the movement and positioning process of the third quantitative bottle 1006b3.

[0090] The present invention provides a rotary sugar-adding device based on a downward pressing lever, which can automatically add syrup to the cup body below the pump head when the selected quantitative bottle automatically rotates to the point where the pump head is directly facing the cup body after the user selects one of several quantitative bottles to add sugar to the cup body. The entire sugar-adding process does not require manual operation, thereby improving the automation and efficiency of sugar-adding brewing.
