[0029] Embodiment 1:

[0030] Please refer to Figure 1-Figure 4 , a liquid vending device, which includes a box body 1, a placing table 2 is fixedly connected to the bottom of one side of the box body 1, three partition plates 3 are detachably connected to the inner side of the box body 1, and the three partition plates 3 divide the inner side of the box body 1 into four placing slots of the same size, a side wall of the box body 1 away from the placing table 2 is provided with a slot, and a box door 4 is rotatably connected to the inner side of the slot through a hinge, a movable plate 5 is arranged on the top of the box body 1, and both ends of the bottom of the movable plate 5 are fixedly connected to support plates 6, and the support plates 6 and the inner sides of the side walls at both ends of the box body 1 are arranged with clearance fit, four extraction components 7 are fixedly connected to the side wall of the box body 1 close to the placing table 2, and the positions of the extraction components 7 correspond to the placing slots, a display screen 8 is fixedly connected to the side wall of the box body 1 close to the placing table 2, and a button 9 is fixedly connected to the side of the display screen 8 away from the box body 1, a tilting component 10 is arranged at the bottom of the inner side of the placing slot, and both ends of the inner side of the placing slot are arranged with clamping components 11;

[0031] The extraction component 7 includes a fixed ball 12, a water outlet pipe 13 and a water intake hose 14. Four fixed balls 12 are fixedly connected to the inner side of the side wall of the box body 1 close to the placement table 2. A water pump is installed inside the fixed ball 12. The positions of the fixed balls 12 correspond to the placement grooves, and the fixed balls 12 are arranged to penetrate the side wall of the box body 1. The fixed ball 12 is located at the bottom of the outer side of the box body 1 and is fixedly connected to the water outlet pipe 13, and the water outlet end of the water outlet pipe 13 is fixedly connected. One end of the fixed ball 12 located on the inner side of the box body 1 is fixedly connected to the water intake hose 14, and the end of the water intake hose 14 close to the fixed ball 12 is fixedly connected to the water pumping end of the water pump, and the end of the water intake hose 14 away from the fixed ball 12 extends to the bottom of the inner side of the bottle body.

[0032] When in use, the box door 4 can be turned over, and the side of the box body 1 away from the placement table 2 is in an open state, and then the bottles are placed in the placement grooves respectively, and then the end of the water intake hose 14 away from the fixing ball 12 is inserted into the inner side of the bottle body, and the bottom of the bottle body is placed inside the tilting component 10 for fixing, and then the box door 4 is closed to make the box body 1 closed;

[0033] When selling, the water cup can be placed on the top of the placing table 2, and the water cup can be placed directly under the extraction component 7 of the corresponding liquid, and then the required liquid can be selected by clicking the button 9, and then the information of the liquid is displayed on the display screen 8;

[0034] After selecting the liquid, the liquid can be pumped through the water pump inside the fixed ball 12 corresponding to the liquid, and the liquid can be pumped from the inside of the bottle to the inside of the water cup through the guidance of the water intake hose 14 and the water outlet pipe 13;

[0035] By setting the tilting assembly 10, when the liquid inside the bottle body gradually decreases, the posture of the bottle body can be gradually adjusted to a tilted state, so that the liquid in the bottle can be further concentrated, thereby facilitating the water intake hose 14 to extract the liquid from the flat bottom;

[0036] At the same time, by setting the clamping assembly 11, when the bagged liquid is placed inside the placement groove, the top of the bagged liquid can be clamped, so that the bagged liquid can also be fixedly placed inside the vending device.

[0037] Embodiment 2:

[0038] This embodiment 2 is used to further disclose the specific structure of the tilting component 10 on the premise of the above embodiment. By coordinating the tilting component 10 with the structures in the above embodiment, the bottle body can be tilted so that the liquid inside the bottle body can be further concentrated, thereby improving the effect of extracting the liquid in the bottle and avoiding the waste of liquid.

[0039] The liquid vending device provided in Example 1 is further optimized. Specifically, Figure 5 As shown, the tilting assembly 10 includes a fixed rod 15, a rotating plate 16, a first spring 17, a first ring 18 and a second ring 19. The fixed rod 15 is fixedly connected to the bottom of the inner side of the placement groove, and the fixed rod 15 is located on the side close to the placement table 2. The rotating plate 16 is rotatably connected to the outer side of the fixed rod 15. The first spring 17 is arranged at the bottom of the rotating plate 16, and the first spring 17 is located on the side away from the fixed rod 15. The top of the first spring 17 is fixedly connected to the bottom of the rotating plate 16, and the bottom of the first spring 17 is fixedly connected to the bottom of the inner side of the box body 1. The first ring 18 and the second ring 19 are arranged at the top and bottom of the outer side of the first spring 17. The first ring 18 and the second ring 19 wrap the first spring 17, and the first ring 18 and the second ring 19 are clearance-fitted.

[0040] The tilting assembly 10 also includes a fixing ring 20, a clamping arc plate 21 and a second spring 22. The fixing ring 20 is fixedly connected to the top center position of the rotating plate 16. Four clamping arc plates 21 are arranged in a circular array on the inner side of the fixing ring 20. A second spring 22 is arranged between the clamping arc plate 21 and the fixing ring 20, and one end of the second spring 22 is fixedly connected to the clamping arc plate 21, and the other end of the second spring 22 is fixedly connected to the inner circumference of the fixing ring 20.

[0041] Specifically: when placing the bottle, the bottom of the bottle can be placed inside the fixing ring 20, and the outer peripheral side of the bottom of the bottle will contact the four clamping arc plates 21. The second spring 22 can be used to squeeze and push the four clamping arc plates 21, so that the outer peripheral side of the bottom of the bottle can be squeezed and clamped by the four clamping arc plates 21, thereby fixing the bottle.

[0042] When the bottle is just put in, the inside of the bottle is full of liquid. At this time, the weight of the bottle presses down the rotating plate 16, so that the rotating plate 16 and the bottom of the inner side of the box 1 are parallel to each other. At this time, the bottom of the rotating plate 16 causes elastic extrusion deformation to the first spring 17, and the second ring 19 at the bottom of the rotating plate 16 is arranged inside the first ring 18.

[0043] As the liquid inside the bottle is gradually extracted, the weight of the bottle itself will also be reduced. At this time, the first spring 17 at the bottom of the rotating plate 16 will gradually push the rotating plate 16 upward through its own elastic setting due to the gradually reduced pressure. At the same time, the rotating plate 16 and the fixed rod 15 are rotatably connected, so that the rotating plate 16 can only rotate with the fixed rod 15 as the center of the circle, and the setting of the rotating plate 16 drives the entire bottle to be tilted. At this time, the liquid inside the bottle will also be concentrated on one side of the fixed rod 15, so that the water intake hose 14 can easily extract the liquid inside the bottle.

[0044] By arranging the movable plate 5 and the supporting plate 6, when there are higher bottles inside the placement groove and the bottles are tilted by the rotating plate 16, the top of the tilted bottles can be adaptively lifted, thereby avoiding the phenomenon that the placement groove cannot be tilted due to higher bottles placed inside the placement groove.

[0045] Embodiment 3:

[0046] This embodiment 3 is used to further disclose the specific structure of the clamping assembly 11 on the premise of the above embodiments. By cooperating with the clamping assembly 11 and the structure in the above embodiments, the top of the bagged liquid can be clamped, thereby achieving the effect of effectively fixing the bagged liquid, thereby improving the effect of extracting the bagged liquid.

[0047] The liquid vending device provided in Example 1 and Example 2 is further optimized. Specifically, Figure 6 As shown, the clamping assembly 11 includes a hollow plate 23, a bidirectional threaded rod 24, a rotating handle 25 and a first rotating seat 26, both ends of each partition plate 3 and both ends of the inner side of the box body 1 are fixedly connected with the hollow plate 23, the inner side of the hollow plate 23 is rotatably connected with the bidirectional threaded rod 24, the side wall of the hollow plate 23 close to the box door 4 is rotatably connected with the rotating handle 25, and the side of the rotating handle 25 close to the bidirectional threaded rod 24 extends to the inner side of the hollow plate 23 and is fixedly connected to the bidirectional threaded rod 24, the outer side of the bidirectional threaded rod 24 is symmetrically arranged with two first rotating seats 26 threadedly connected, and the two first rotating seats 26 are both clearance-fitted with the inner side of the hollow plate 23.

[0048] The clamping assembly 11 also includes a clamping straight plate 27, a second rotating seat 28 and a rotating connecting plate 29. A clamping straight plate 27 is provided at one end of the hollow plate 23 located on the inner side of the placement groove. Two second rotating seats 28 are fixedly connected to the middle of the clamping straight plate 27 near one end of the hollow plate 23. A rotating connecting plate 29 is provided between each second rotating seat 28 and each first rotating seat 26, and one end of the rotating connecting plate 29 is rotatably connected to the second rotating seat 28, and the other end of the rotating connecting plate 29 is rotatably connected to the first rotating seat 26.

[0049] Specifically: after placing the bagged liquid into the placement slot, the rotating handle 25 can be rotated, and the bidirectional threaded rod 24 can be driven to rotate by rotating the rotating handle 25. During the rotation of the bidirectional threaded rod 24, the two first rotating seats 26 can be driven to move symmetrically and synchronously.

[0050] When the two first rotating seats 26 are approaching each other, the two second rotating seats 28 can be simultaneously pushed toward the end away from the hollow plate 23 by rotating the connection and support arrangement of the connecting plate 29, and the clamping straight plate 27 can be pushed to move synchronously;

[0051] Therefore, the clamping straight plates 27 at both ends of the inner side of the placement groove can clamp the top of the bagged liquid. After the bagged liquid is fixed, the box door 4 can be closed to make the inner side of the box body 1 closed.
