[0031] Combined with Figure 1-7 As shown, a water cup with an inner cup liftable function includes a cup body 1 and a base 2 detachably connected to the bottom of the cup body 1. In this embodiment, the base 2 is coaxially arranged with the body 1, and the base 2 and the cup body 1 are threadedly connected.

[0032] The cup body 1 includes an outer cup 101 and a foldable inner cup 102 coaxially arranged in the outer cup 101 . The foldable inner cup 102 is built in the outer cup 101 , and the foldable inner cup 102 can be contracted and expanded along the axis of the outer cup 101 .

[0033] A fixing seat 103 detachably connected to the outer cup 101 is fixedly provided on the upper part of the foldable inner cup 102. The fixing seat 102 is annular in structure and is fixedly connected to the upper part of the foldable inner cup 102 to form an integrated structure. The connection between the foldable inner cup 102 and the outer cup 101 is achieved through the detachable connection between the fixing seat 103 and the upper end of the outer cup 101.

[0034] Furthermore, an inner upper portion of the fixing seat 103 is provided with an inwardly concave arc structure, which facilitates drinking when using the water cup.

[0035] The fixing seat 103 is located on both sides of the folding inner cup 102 and is provided with a screw rod 3 extending into the base 2. Specifically, both ends of the screw rod 3 are rotatably connected to the fixing seat 103 and the base 2 respectively through bearings.

[0036] In this embodiment, the screw rod 3 is symmetrically arranged on both sides of the folding inner cup 102 and is arranged parallel to the axial direction of the outer cup 101. During implementation, the folding inner cup 102 can be contracted and expanded in the outer cup 101 through the forward and reverse rotation of the screw rod 3, thereby achieving the lifting of the water level in the folding inner cup 102 for convenient drinking.

[0037] A threaded tube 4 cooperating with the screw rod 3 is provided at the bottom of the foldable inner cup 102. Specifically, the threaded tube 4 is sleeved on the screw rod 3. An internal thread cooperating with the thread of the screw rod 3 is provided in the threaded tube 4. When in use, the threaded tube 4 can be moved up and down on the screw rod 3 by the forward and reverse rotation of the screw rod 3. At the same time, since the threaded tube 4 is fixedly connected to the bottom of the foldable inner cup 102, the contraction and expansion of the foldable inner cup 102 in the outer cup 101 can be realized.

[0038] The base 2 is provided with a driving mechanism 5 connected to the screw rod 3. In a specific implementation, the driving mechanism 5 drives the screw rod 3 to rotate forward and reverse.

[0039] Specifically, the driving mechanism 5 includes a driving motor 501 and a driving gear 502. During implementation, a mounting cavity is provided in the base 2, and the driving motor 501 is fixedly disposed in the base 2. When installed, the driving motor 501 is coaxially disposed with the base 2.

[0040] The driving gear 502 is arranged on the output shaft of the driving motor 501, and connecting gears 503 meshing with the driving gear 502 are arranged on both sides of the driving gear 502 in the base 2. The connecting gears 503 are symmetrically arranged on both sides of the driving gear 502. At the same time, through the setting of the connecting gears 503, the rotation directions of the screw rods 3 on both sides of the folding inner cup 102 can be guaranteed to be the same.

[0041] Furthermore, specifically, the connecting shaft of the connecting gear 503 is rotatably connected to the base 2 via a bearing, which can ensure the rotatable setting of the connecting gear 503 in the base 2.

[0042] During implementation, the driving motor 501 drives the driving gear 502, thereby driving the connecting gear 503;

[0043] The screw rod 3 is provided with a driven gear 504 meshing with the connecting gear 503. The driven gear 504 is fixedly mounted on the screw rod 3 and meshing with the connecting gear 503. During implementation, the driven gear 504 is driven by the rotation of the connecting gear 503, thereby realizing the rotation of the screw rod 3. Moreover, the forward and reverse drive of the screw rod 3 can be realized by the forward and reverse rotation of the driving motor 501.

[0044] The base 2 is provided with a battery 6 and a controller 7 connected to the driving mechanism 5. Specifically, the battery 6, the driving motor 501, the rising button 8 and the descending button 9 are all electrically connected to the controller 7. During implementation, the battery 6 provides electric energy for the driving mechanism 5. When the rising button 8 is pressed, the driving motor 501 is controlled by the controller 7 to realize the forward driving of the driving gear 502, and then the forward rotation of the driven gear 504 is realized through the setting of the connecting gear 503, so as to realize the forward rotation of the screw rod 3, and finally realize the contraction of the folding inner cup 102 in the outer cup 101, and realize the lifting of the water surface in the folding inner cup 102;

[0045] Similarly, by pressing the descending button 9 , the reverse rotation of the driving mechanism 5 is realized, so that the screw rod 3 rotates in the opposite direction, and finally the folded inner cup 102 is unfolded in the outer cup 101 .

[0046] Furthermore, the base 2 is provided with a stop switch 12 connected to the controller 7. Specifically, the stop switch 12 is arranged in the middle position of the upper side of the base 2 and is electrically connected to the controller 7. During implementation, when the folding inner cup 102 is in the process of unfolding and descending, the bottom of the folding inner cup 102 gradually approaches the motor stop switch. When the bottom of the folding inner cup 102 drops to the lowest point, at this time, the bottom of the folding inner cup 102 exerts a force on the stop switch 12, thereby disconnecting the switch, and the controller 7 controls the drive motor 501 to stop working.

[0047] An upward button 8 and a downward button 9 connected to the controller 7 are provided on the upper outer side of the cup body 1. The upward button 8 and the downward button 9 are connected to the controller 7. By pressing the corresponding buttons, the direction of the driving motor 501 in the driving mechanism 5 can be controlled, thereby controlling the contraction and expansion of the foldable inner cup 102.

[0048] The cup cover 10 is also included, and the cup cover 10 is threadedly connected to the upper end of the fixing seat 103. The threaded connection between the cup cover 10 and the fixing seat 103 can achieve cooperation with the cup body 1 to achieve sealing of the water cup.

[0049] The controller 7 further includes a charging port 11 , which is electrically connected to the controller 7 . The battery 6 can be charged through the charging port 11 .

[0050] During the implementation of the utility model, the driving motor 501 is controlled to rotate (forward or reverse) by pressing the rising button 8 and the falling button 9, and the driving motor 501 and the connecting gear 503 and the driven gear 504 are controlled to control the rotation of the screw rod 3, so as to adjust the position of the threaded tube 4 on the screw rod 3, so as to control the state (contraction or expansion) of the folding inner cup 102 in the outer cup 101;

[0051] Specifically, when the folding inner cup 102 is in the process of contraction, the controller 7 controls the forward rotation of the driving motor 501 to realize the forward driving of the driving gear 502, and then realizes the forward rotation of the driven gear 504 through the setting of the connecting gear 503, so as to realize the forward rotation of the screw rod 3, and finally realizes the contraction of the folding inner cup 102 in the outer cup 101, and realizes the lifting of the water surface in the folding inner cup 102;

[0052] When the folding inner cup 102 is in the process of unfolding, the controller 7 controls the reverse rotation of the driving motor 501 to realize the reverse drive of the driving gear 502, and then realizes the reverse rotation of the driven gear 504 through the setting of the connecting gear 503, so as to realize the reverse rotation of the screw rod 3, and finally realizes the unfolding of the folding inner cup 102 in the outer cup 101. At the same time, when the folding inner cup 102 is in the process of unfolding and descending, the bottom of the folding inner cup 102 gradually approaches the motor stop switch. When the bottom of the folding inner cup 102 drops to the lowest point, at this time, the bottom of the folding inner cup 102 exerts a force on the stop switch 12, thereby disconnecting the switch, and the controller 7 controls the driving motor 501 to stop working.

[0053] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
