[0038] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figures 1-6 As shown, one embodiment of the present invention provides a water cup, comprising a first cylinder 1, a folding inner cup 2, a spring 3, a first limiting mechanism 4 and a second limiting mechanism 5;

[0040] The foldable inner cup 2 is located in the first cylindrical body 1 and has a communicating opening and a receiving cavity, wherein the receiving cavity is used to receive liquid;

[0041] One end of the foldable inner cup 2 close to its opening is connected to the first cylinder 1, and the other end is fixedly connected to the support plate 6;

[0042] A cavity is formed between the support plate 6 and the bottom wall of the first cylinder 1. A first limiting mechanism 4 and a spring 3 are provided in the cavity. The length direction of the spring 3 is parallel to the axial direction of the first cylinder 1. The spring 3 is used to support the support plate 6. The first limiting mechanism 4 and the spring 3 cooperate to adjust the distance from the support plate 6 to the bottom wall of the first cylinder 1.

[0043] The second limiting mechanism 5 is provided between the support plate 6 and the side wall of the first cylinder 1 , and is used for guiding the support plate 6 to move along the axial direction of the first cylinder 1 .

[0044] By arranging a spring 3 in the cavity, and the spring 3 is always in a compressed state, a supporting force is given to the support plate 6 along the bottom wall of the first cylinder 1 to the top of the first cylinder 1. The first limiting mechanism 4 is used to limit the extension and contraction degree of the spring 3, so that the first limiting mechanism 4 and the spring 3 work together to adjust the distance from the support plate 6 to the bottom wall of the first cylinder 1. Due to the second limiting mechanism 5, the support plate 6 can be guided to move along the axial direction of the first cylinder 1. Therefore, when the water source in the accommodating chamber is small, the first limiting mechanism 4 and the spring 3 work together to make the support plate 6 move smoothly along the direction from the bottom wall of the first cylinder 1 to the top of the first cylinder 1. The distance from the support plate 6 to the bottom wall of the first cylinder 1 increases, and the distance from the bottom of the foldable inner cup 2 to the cup mouth of the foldable inner cup 2 decreases, and the volume of the accommodating chamber decreases. Even if the water source is small, there is no need to tilt the cup significantly to drink water, and there will be no situation where the water in the accommodating chamber is splashed out due to insufficient force to tilt the cup, which is not easy to cause waste of water resources.

[0045] Among them, the first cylinder 1 includes an annular shell and a circular plate fixedly connected to one end of the annular shell. The circular plate is the bottom wall of the first cylinder 1. The annular shell and the circular plate make the first cylinder 1 form a cylinder with an open port at one end. The second cylinder 7 is a cylinder with open ports at both ends. The cup mouth of the folding inner cup 2 is the opening of the folding inner cup 2. The folding inner cup 2 is a folding tube. Preferably, one end of the folding tube is sealed and the other end is the opening of the folding tube. The sealed end of the folding tube is fixed to the support plate 6.

[0046] like Figure 1-Figure 3 As shown, according to one embodiment of the present utility model, the end of the first cylinder 1 away from the opening is fixedly connected to the second cylinder 7, a bottom plate 8 is provided in the second cylinder 7, a first through hole 101 is provided on the bottom wall of the first cylinder 1, one end of the spring 3 is rotatably connected to the support plate 6, and the other end thereof passes through the first through hole 101 and is fixedly connected to the bottom plate 8.

[0047] The support plate 6 is perpendicular to the axial direction of the first cylinder 1 .

[0048] It should be noted that one end of the spring 3 is rotatably connected to the support plate 6 so that the length direction of the spring 3 is not easily changed, thereby allowing the spring 3 to always give the support plate 6 a force along the bottom wall of the first cylinder 1 to its top.

[0049] like Figure 3 and Figure 4As shown, according to one embodiment of the present utility model, a first one-way gear ring 9 is fixedly connected to the base plate 8, a second one-way gear ring 10 is fixedly connected to the bottom of the second cylinder 7, the second one-way gear ring 10 is located below the first one-way gear ring 9, the first one-way gear ring 9 and the second one-way gear ring 10 are meshed, and a toggle pin 11 is fixedly connected to the bottom of the base plate 8.

[0050] After the spring 3 has been used for a period of time, the elastic performance of the spring 3 decreases. In order to enable the spring 3 to continue to provide stable supporting performance to the support plate 6, the bottom plate 8 is pushed toward the bottom wall of the first cylinder 1 to its top end, so that the first one-way gear ring 9 and the second one-way gear ring 10 are separated. The toggle pin 11 is manually screwed to drive the bottom plate 8 to rotate, and then drive the spring 3 with one end fixedly connected to the bottom plate 8 to rotate, and then the part of the spring 3 located between the bottom wall of the first cylinder 1 and the bottom plate 8 enters the cavity through the first through hole 101. By lengthening the length of the spring 3 located in the cavity, the problem of its elasticity decrease is compensated, so that the spring 3 can play a long-term and stable supporting role.

[0051] Of course, in this embodiment, the spring 3 can also abut against the bottom wall of the support plate 6. Its purpose does not deviate from the design concept of the present invention, and therefore, should fall within the scope of protection of the present invention.

[0052] like Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the first limiting mechanism 4 includes a driving assembly, a rope 401, a rotating shaft 402, a mounting frame 403, a connecting rod 405 and a roller 404;

[0053] Both ends of the roller 404 are rotatably connected to a connecting rod 405, and the connecting rod 405 is fixedly connected to the support plate 6. A second through hole is formed between the roller 404 and the support plate 6;

[0054] The bottom end of the mounting bracket 403 is fixedly connected to the bottom wall of the first cylinder 1. One end of the rope 401 is fixedly connected to the mounting bracket 403, and the other end thereof passes through the second through hole and is connected to the rotating shaft 402.

[0055] The driving assembly is used to drive the rotating shaft 402 to rotate around its axis.

[0056] It should be noted that the first limiting mechanism 4 is used to limit the extension and contraction degree of the spring 3 .

[0057] The axis of the roller 404 is parallel to the axis of the rotating shaft 402 .

[0058] Each roller 404 corresponds to two connecting rods 405 .

[0059] Part of the rope 401 is wrapped around the rotating shaft 402, and the driving assembly is provided to drive the rotating shaft 402 to rotate, thereby reducing the rope 401 wrapped around the rotating shaft 402. At this time, the support plate 6 can be away from the bottom wall of the first cylinder 1 under the action of the spring 3, thereby reducing the volume of the accommodating chamber. When the water source in the accommodating chamber is small, due to the reduction in the volume of the accommodating chamber, the surface of the water source can be located at the opening position of the folding inner cup 2. People can drink water by slightly tilting the cup, which is very convenient.

[0060] like Figure 6 As shown, according to one embodiment of the present invention, the drive assembly includes a drive motor 406, a gear 407 and a support frame 408. The output end of the drive motor 406 is fixedly connected to a worm 409. The rotating shaft 402 is rotatably connected to the support frame 408. One end of the rotating shaft 402 is fixedly connected to the gear 407. The worm 409 meshes with the gear 407.

[0061] The axial direction of the rotating shaft 402 is perpendicular to the axial direction of the first cylinder 1 .

[0062] The fixed end of the driving motor 406 is fixedly connected to the mounting bracket 403 .

[0063] Among them, both ends of the roller 404 are rotatably connected with a connecting rod 405, so as to prevent the rope 401 from running out of the second through hole, thereby causing the first limiting mechanism 4 to lose its function. The connecting rod 405 includes a fixedly connected rod body and a circular shaft. Circular grooves are provided at both ends of the roller 404, and the circular shaft is rotatably connected in the circular grooves. The rod body is fixedly connected to the support plate 6. One roller 404 and two connecting rods 405 are recorded as a group. Two groups of rollers 404 and connecting rods 405 can be provided, and are symmetrically arranged at the bottom of the support plate 6. The two groups of rollers 404 and connecting rods 405 make the support plate 6 more stable when moving along the axial direction of the first cylinder 1, so that the water source in the accommodating chamber will not shake significantly when the support plate 6 moves.

[0064] According to an embodiment of the present invention, the mounting frame 403 includes a mounting plate and a connecting plate, wherein the mounting plate is fixed to the bottom wall of the first cylinder 1 via the connecting plate. The mounting plate is parallel to the supporting plate 6, and the connecting plate is perpendicular to the supporting plate 6.

[0065] Furthermore, the support frame 408 includes two side plates and a sleeve. The two ends of the sleeve are fixedly connected to the two side plates, and the two side plates are fixedly connected to the bottom wall of the first cylinder 1. A notch is formed on the sleeve. One end of the rope 401 is fixedly connected to the rotating shaft 402, and the other end thereof passes through the notch and the two first through holes 101 in sequence, and is fixedly connected to the mounting plate in the mounting frame 403.

[0066] A circular hole is provided on the rotating shaft 402, and a connecting shaft is fixedly connected in the circular hole. The connecting shaft is rotatably connected to the two side plates. The axis of the connecting shaft coincides with the axis of the rotating shaft 402. One end of the connecting shaft passes through one of the side plates and is fixedly connected to the gear 407 (that is, one end of the rotating shaft 402 is fixedly connected to the gear 407 through the connecting shaft). The rotating shaft 402 is located in the sleeve, and the diameter of the sleeve is larger than the diameter of the rotating shaft 402.

[0067] The length direction of the worm 409 is perpendicular to the axis direction of the gear 407 .

[0068] The driving motor 406 drives the worm 409 to rotate around its axis, and then drives the gear 407 engaged with the worm 409 to rotate. The rotating shaft 402 is driven by the gear 407 to rotate, and the rope 401 is wound up, so that the support plate 6 is pulled close to the bottom wall of the first cylinder 1 by the rope 401, thereby increasing the volume of the accommodating cavity of the folding inner cup 2.

[0069] Of course, in this embodiment, the driving assembly can also be in other forms. For example, the driving assembly includes a servo motor, and the output end of the servo motor is connected to the rotating shaft 402. When the diameter of the first cylinder 1 is large, it can be applied.

[0070] like Figure 6 As shown, according to one embodiment of the present invention, the second limiting mechanism 5 includes a plurality of limiting blocks 501 fixedly connected to the peripheral side of the support plate 6;

[0071] Around the axis of the first cylinder 1, a plurality of limiting rods 502 are fixedly connected to the inner side wall of the first cylinder 1, and the limiting rods 502 correspond to the limiting blocks 501 one by one;

[0072] Along the length direction of the limiting rod 502, a sliding groove is provided on the limiting rod 502, and the limiting block 501 is slidably connected in the sliding groove;

[0073] The length direction of the limiting rod 502 is the same as the axial direction of the first cylinder 1 .

[0074] By providing the limit block 501 and the sliding groove, the support plate 6 can be prevented from tilting during movement, thereby improving stability.

[0075] Furthermore, the limit block 501 is a T-shaped block and the slide groove is a T-shaped groove. In this case, even if only one set of limit blocks 501 and limit rods 502 is provided, the support plate 6 can only move along the axial direction of the first cylinder 1 .

[0076] like Figure 3As shown, according to one embodiment of the present invention, a connecting ring 12 is connected to the opening of the folding inner cup 2, and a conical annular groove is provided on the inner wall of the connecting ring 12. The diameter of the conical annular groove close to one end of the bottom wall of the first cylinder 1 is smaller than the diameter of the other end, and the connecting ring 12 is connected to the first cylinder 1.

[0077] Since the distance between the opening of the foldable inner cup 2 and the outer wall of the first cylinder 1 is somewhat large, it is not very convenient to drink water. By providing a connecting ring 12 with a conical ring groove, the distance from the water source to the outer wall of the first cylinder 1 is reduced, which makes it more convenient for people to drink water.

[0078] It should be noted here that a support ring is fixedly connected to the outer wall of the connecting ring 12, and the connecting ring 12 is fixedly connected to the first cylinder 1 through the support ring. The support ring can support the folding inner cup 2.

[0079] like Figure 1 As shown, according to one embodiment of the present invention, a cover 13 for sealing the opening of the foldable inner cup 2 is screwed onto the connecting ring 12. By sealing the opening of the foldable inner cup 2, the accommodating cavity is sealed, and water will not spill out.

[0080] An internal thread is provided on the inner wall of the cover body 13, and an external thread is provided on the outer wall of the connecting ring 12. When the cover body 13 is screwed into place, the cover body 13 abuts against the support ring. Therefore, the support ring can also prevent the cover body 13 from being over-screwed.

[0081] like Figure 2 As shown, according to one embodiment of the present invention, a first switch 14 and a second switch 15 are provided on the first cylinder 1, a controller is provided in the first cylinder 1, and the first switch 14, the second switch 15 and the drive motor 406 are all electrically connected to the controller.

[0082] The first switch 14 is used to control the drive motor 406 to rotate forward, and the second switch 15 is used to control the drive motor 406 to rotate reversely; alternatively, the first switch 14 is used to control the drive motor 406 to rotate reversely, and the second switch 15 is used to control the drive motor 406 to rotate forward.

[0083] When the volume of the accommodating chamber needs to be adjusted, the first switch 14 or the second switch 15 is pressed according to actual conditions to change the size of the accommodating chamber.

[0084] Specifically, pressing the first switch 14 drives the motor 406 to rotate forward, and the worm 409 rotates accordingly, driving the gear 407 to rotate, so that the rotating shaft 402 releases the rope 401, and the compression degree of the spring 3 is reduced, pushing the support plate 6 in the direction away from the bottom wall of the first cylinder 1. The multiple limit blocks 501 fixedly connected to the side of the support plate 6 slide in the slide groove of the limit rod 502, so that the support plate 6 moves along the bottom wall of the first cylinder 1 to its top, and the volume of the accommodating chamber is reduced. After the volume of the accommodating chamber is reduced to a certain extent, the first switch 14 is released, and the drive motor 406 stops running. Even if there is less water in the accommodating chamber, there is no need to tilt the cup significantly to drink water, which is more convenient and less likely to cause water resources to spill out.

[0085] When the volume of the accommodating chamber needs to be expanded, the second switch 15 is pressed to reverse the driving motor 406 , and then the support plate 6 moves from the top of the first cylinder 1 to the bottom wall thereof.

[0086] After the spring 3 has been used for a period of time, the bottom plate 8 is pushed toward the top of the first cylinder 1 (the spring 3 between the bottom wall of the first cylinder 1 and the bottom plate 8 is contracted at this time), the first one-way toothed ring 9 and the second one-way toothed ring 10 are separated, and the toggle pin 11 is screwed, so that the portion of the spring 3 between the bottom wall of the first cylinder 1 and the bottom plate 8 enters the cavity through the first through hole 101. By changing the length of the spring 3 in the cavity, the insufficient elastic force of the spring 3 under long-term use is compensated, thereby extending the service life of the water cup. After the screwing is completed, the toggle pin 11 is released. At this time, the bottom plate 8 moves away from the bottom wall of the first cylinder 1 under the action of the spring 3, and the first one-way toothed ring 9 and the second one-way toothed ring 10 are engaged, preventing the toggle pin 11 from being accidentally touched, causing the bottom plate 8 to drive the spring 3 between the bottom wall of the first cylinder 1 and the bottom plate 8 to rotate through the first through hole 101 and enter the cavity.
