[0002] Disposable paper cups are common drinking utensils in many households and public places. In order to facilitate the use of disposable paper cups, disposable paper cups are usually stacked in a paper cup rack. When a disposable paper cup is needed, the cup at the bottom of the paper cup rack can be directly taken out.

[0003] Existing paper cup racks all use the method of directly extracting cups from the bottom. The stacked cups in the paper cup rack are restricted by elastic sheets to the cup at the bottom. When taking out cups, there is a probability that multiple cups will be taken out at one time. It is inconvenient to put the extra cups back into the paper cup rack. If they are placed randomly, they are easily contaminated. If they are discarded, it will cause waste, which greatly affects the user experience of the product. Summary of the invention

[0049] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0050] In view of the problem that there is a probability of taking out two or more cups at a time when taking cups from the existing paper cup cylinder holder, this embodiment provides a method for dropping a paper cup into the holder. Through the cooperation of the driving member 200 and the limiting member 300, it can ensure that only one cup is output each time, greatly improving the user experience of the product.

[0051] It should be noted that the outer periphery of the top end of a disposable paper cup has an outwardly convex cup rim, and this method for dropping a paper cup into the holder exerts a restriction on the cup by supporting the cup rim.

[0052] A method for dropping a paper cup into the holder:

[0053] The paper cup holder is equipped with a cup dropping device and a driving member 200. The cup dropping device can support and limit the lowermost cup and press and push it downward. At the same time, the cup dropping device can support and limit the cups stacked above the lowermost cup, and the driving member 200 can drive the cup dropping device to act;

[0054] The cup dropping method includes the following steps:

[0055] S1: The driving member 200 drives the cup dropping device to support the cups stacked above the lowermost cup;

[0056] S2: The driving member 200 drives the cup dropping device to cancel the support for the lowermost cup;

[0057] S3: The driving member 200 drives the cup dropping device to press the lowermost cup downward;

[0058] S4: The driving member 200 drives the cup dropping device to reset.

[0059] In this embodiment, as Figures 1-5 shown, the cup dropping device includes a base 100, a limiting member 300, and a first elastic member 400. The first elastic member 400 preferably uses a spring;

[0060] The base 100 has a passage for the paper cup to pass through. At least two limiting members 300 are circumferentially and evenly installed in the passage. Preferably, the number of the limiting members 300 is three. The driving member 200 is sleeved outside the base 100. The driving member 200 can slide axially along the base 100 or rotate around the axis of the base 100. One end of the first elastic member 400 is connected to the driving member 200, and the other end is connected to the base 100;

[0061] The driving member 200 drives the limiting member 300 to act through vertical movement or rotation, and the driving member 200 is driven to reset by the first elastic member 400;

[0062] The limiting member 300 includes a first elastic arm 310, a second elastic arm 320, and a lower cup pusher 330. The first elastic arm 310 and the second elastic arm 320 are spaced apart and installed on the base 100. A first supporting portion 311 for supporting the cup rim is provided at the top of the first elastic arm 310. A second supporting portion 321 for supporting the cup rim is provided at the top of the second elastic arm 320. The lower cup pusher 330 is slidably installed on the second supporting portion 321. The lower cup pusher 330 can slide vertically. A second elastic member is provided between the lower cup pusher 330 and the second elastic arm 320. The second elastic member preferably uses a spring; specifically, a vertical sliding groove 322 is provided on the second supporting portion 321, and the lower cup pusher 330 is slidably installed in the vertical sliding groove 322; it should be noted that the "elastic arm" specifically refers to that the materials of the first elastic arm 310 and the second elastic arm 320 themselves are elastic, including but not limited to plastic materials and metal materials.

[0063] In the initial state, the top end of the first elastic arm 310 inclines inward, and the first supporting portion 311 supports the cup rim of the lowermost cup. In the working state, the top end of the first elastic arm 310 swings outward, and the first supporting portion 311 moves out from the cup rim;

[0064] In the initial state, the first elastic arm 310 is located outside the lowermost cup. In the working state, the top end of the second elastic arm 320 inclines inwards, and the second supporting portion 321 moves above the rim of the lowermost cup to support the stacked cups above.

[0065] In the initial state, the lower cup pusher 330 is located at the top end of the second elastic arm 320. In the working state, the lower cup pusher 330 moves downwards and pushes against the rim of the lowermost cup.

[0066] The driving member 200 has three driving strokes. In the first driving stroke, the driving member 200 drives the top end of the second elastic arm 320 to swing inwards, and the second elastic arm 320 changes from the initial state to the working state, and the second supporting portion 321 moves above the rim of the lowermost cup below. In the second driving stroke, the driving member 200 drives the top end of the first elastic arm 310 to swing outwards, and the first supporting portion 311 moves out from below the rim of the lowermost cup, and the first elastic arm 310 changes from the initial state to the working state. In the third driving stroke, the driving member 200 drives the lower cup pusher 330 to move downwards, and by pressing against the rim of the lowermost cup, the lowermost cup is pushed downwards, and the lower cup pusher 330 changes from the initial state to the working state, and the second elastic member is deformed by force. During the movement of the driving member 200, the first elastic member 400 is deformed by force. After the driving member 200 drives the limiting member 300 to act, the first elastic member 400 can drive the driving member 200 to reset. The first elastic arm 310 and the second elastic arm 320 can be reset by their own elastic forces, and the second elastic member can drive the lower cup pusher 330 to reset.

[0067] In this embodiment, as Figures 2-3 shown, the first elastic arm 310 has a first driving portion 312, the second elastic arm 320 has a second driving portion 323, and the lower cup pusher 330 has a third driving portion 332.

[0068] In this embodiment, the driving member 200 drives the limiting member 300 to act by sliding downwards;

[0069] As Figure 5 shown, the driving member 200 has a first pressing member 210 for pressing against the first driving portion 312, a second pressing member 220 for pressing against the second driving portion 323, and a third pressing member 230 for pressing against the third driving portion 332;

[0070] The third pressing member 230 is located above the first pressing member 210, and the second pressing member 220 is located below the first pressing member 210;

[0071] As Figures 2-5As shown, the first pressing and pushing member 210 is a guiding surface, and the guiding surface includes a vertical plane at the upper part and an inclined plane at the lower part; specifically, the first elastic arm 310 has an extending portion extending towards the driving member 200, and a driving surface cooperating with the guiding surface is arranged on the side surface of the extending portion facing the first elastic arm 310. This driving surface is the first driving portion 312. In the initial state, the guiding surface is located above the driving surface, and the extrusion between the inclined plane at the lower part of the guiding surface and the driving surface can swing the upper end of the first elastic arm 310 outwards. The cooperation between the vertical plane at the upper part of the guiding surface and the driving surface can keep the first elastic arm 310 in a state where the first supporting portion 311 is located outside the cup rim.

[0072] The second pressing and pushing member 220 is a through hole, and the second driving portion 323 can be sleeved in the through hole. The second driving portion 323 includes an upper inclined plane cooperating with the top surface of the through hole and a lower inclined plane cooperating with the bottom surface of the through hole; specifically, the second driving portion 323 is an isosceles triangle convex portion extending towards the driving member 200 on the second elastic arm 320. The upper inclined plane and the lower inclined plane are two waist sides of the isosceles triangle convex portion, and there is an arc transition at the junction of the upper inclined plane and the lower inclined plane.

[0073] As Figures 2-5 shown, the third pressing and pushing member 230 is a pressing block. The lower cup pushing member 330 has a lower rod extending downwards, and a pressing surface is arranged at the end of the lower rod. This pressing surface is the third driving portion 332, and the pressing block is located above the pressing surface; specifically, a groove 240 is arranged at the top end of the driving member 200 to avoid the lower cup pushing member 330, and the pressing block is arranged at the top end of the side wall of the groove 240; in the initial state, the pressing surface of the lower cup pushing member 330 is located outside the pressing block. When the second elastic arm 320 moves to the working state, the pressing surface moves directly below the pressing block.

[0074] In this embodiment, as Figure 3 shown, to ensure the stability of the sliding of the lower cup pushing member 330, the bottom surface of the lower cup pushing member 330 has a first vertical guiding rod 331, a first vertical slot is arranged on the second elastic arm 320, the bottom end of the first vertical guiding rod 331 is inserted into the first vertical slot, and the second elastic member is arranged at the inner bottom of the first vertical slot.

[0075] In this embodiment, as Figure 1 、 Figure 4 shown, to ensure the stability of the vertical sliding of the lower driving member 200, a plurality of second vertical guiding rods 110 are evenly distributed in a circumferential direction on the base 100, a second vertical slot is arranged at the bottom end of the driving member 200, the top ends of the second vertical guiding rods 110 are inserted into the second vertical slot, and the first elastic member 400 is sleeved on the second vertical guiding rods 110.

[0078] Specifically, the second elastic arm 320 is integrally injection-molded with the bracket 340, and the first elastic arm 310 is detachably connected to the bracket 340. Preferably, the bottom end of the first elastic arm 310 is hinged to the bracket 340, a spring is provided between the bottom end of the first elastic arm 310 and the side wall of the bracket 340, and the rotation matching portion of the first elastic arm 310 and the bracket 340 is located between the first supporting portion 311 and the spring. At the same time, a stop portion for restricting the inner swing of the top end of the first elastic arm 310 is provided on the bracket 340. In the initial state, the first elastic arm 310 abuts against the stop portion, and the first elastic arm 310 is in a state where the top end inclines inward, and the first supporting portion 311 supports the rim of the lowermost cup. Of course, the bottom end of the first elastic arm 310 and the bracket 340 can also be snap-fixed after being plugged in place.

[0079] In this embodiment, as Figure 2 、 Figure 4 shown, a convex 342 is provided on the plug-in portion 341, and a clamping groove is provided on the side wall of the slot 130, and the clamping groove can be snap-fastened with the convex 342.
