[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0039] Please refer to Figures 1-13 A pet water dispenser includes a shell 1 as the main structure of the whole water dispenser, which plays a role in protecting and supporting the internal components. The bottom of the shell 1 is provided with a bottom layer 12, and the middle of the inside of the shell 1 is provided with a lifting layer 11, and the lifting layer 11 is provided with a water drinking device not shown in the figure. The water drinking device is a prior art, which provides clean drinking water for pets. The lifting device 2 and the driving device 4 are arranged between the bottom layer 12 and the lifting layer 11. The bottom layer 12 is located at the bottom of the water dispenser and is the supporting basis of the lifting layer 11 and the driving device 4. The lifting connecting frame 3 is connected between the lifting device 2 and the driving device 4, which connects the lifting device 2 and the driving device 4 as a whole, so that the lifting device 2 can indirectly move up and down the driving device 4 connected to the lifting connecting frame 3. The lifting connecting frame 3 is arranged at the bottom of the lifting layer 11, and the lifting device 2 hides the driving device 4 inside the bottom layer 12 and keeps it stationary as a whole or extends out of the bottom layer 12 to contact the ground to drive the whole to move. When the water dispenser is stationary, the bottom layer 12 is in contact with the ground to provide stable support; when the water dispenser needs to move, the driving device 4 on the bottom layer 12 will extend out and contact the ground to provide the ability to move.

[0040] The top of the shell 1 is provided with a water storage groove 14, and the middle of the water storage groove 14 is provided with a water outlet 13. The water drinking device inside the shell 1 will send drinking water out of the water outlet 13 and store it in the water storage groove 14, which is convenient for pets to drink.

[0041] The lifting layer 11 is slidably assembled inside the shell 1. When the water dispenser is stationary, the driving device 4 is hidden inside the bottom layer 12, and the distance between the bottom layer 12 and the lifting layer 11 is far; when the water dispenser needs to move, the lifting device 2 will move the lifting connecting frame 3 downward, that is, the distance between the lifting layer 11 and the bottom layer 12 becomes short, so that the driving device 4 extends out of the displacement opening one 121 and the displacement opening two 122 of the bottom layer 12.

[0042] The lifting device 2 includes two sliding frames 22, a clamping frame 1 27 and a clamping frame 28. A fixed frame 221 is provided at the bottom of the two sliding frames 22. The fixed frame 221 is fixedly installed on the bottom layer 12. A slide groove 222 is provided on the sliding frame 22. The sliding frame 22 serves as a motion limiting device for the lifting rod 29, so that one end of the lifting rod 29 can slide in the slide groove 222 of the sliding frame 22, thereby lifting the top plate 21 therein and realizing the up and down movement of the lifting connecting frame 3.

[0043] Clamping frame 1 27 and clamping frame 2 28 are assembled with each other and fixedly mounted on the bottom layer 12. Clamping frame 1 27 is mounted with one end of two screw rods 23. The other end of the screw rods 23 is mounted with a bearing seat 24, and the bearing seat 24 is fixedly mounted on the bottom layer 12. Clamping frame 1 27 and clamping frame 2 28 are used to fix the screw rods 23 and motor 1 26, and the motor 1 26 drives the two screw rods 23 to move in the same manner.

[0044] The screw rod 23 is equipped with a slider 25, and the slider 25 is provided with a connecting piece 251. One end of the connecting piece 251 is rotatably connected to the lifting rod 29, and the other end of the lifting rod 29 is slidably assembled in the slide groove 222 of the sliding frame 22. The lifting rod 29 will move under the drive of the slider 25. As the end of the lifting rod 29 connected to the connecting piece 251 moves, the one end of the lifting rod 29 slidably assembled in the slide groove 222 of the sliding frame 22 will move up and down. When it moves upward, it will push the top plate 21 on the sliding frame 22 upward, thereby pushing the lifting connecting frame 3 upward, realizing the recovery and hiding of the driving device 4, making the water dispenser stationary; when it moves downward, the upper part of the top plate 21 will move downward due to the gravity of the lifting layer 11 and the drinking device, thereby pushing the lifting connecting frame 3 downward and pushing the driving device 4 downward, making the water dispenser movable.

[0045] The top of the sliding frame 22 is also vertically slidably equipped with a top plate 21, and the top of the top plate 21 is fixedly connected to the bottom of the lifting connecting frame 3. The top plate 21 moves up and down under the effect of the lifting rod 29, and is about to lift the connecting frame 3 and push and pull it up and down.

[0046] The motor 26 is arranged on the clamping frame 27, and the eccentric shaft 261 is arranged on the motor 26. The eccentric shaft 231 is arranged at one end of the lead screw 23 in the clamping frame 27. The clamping frame 27 is provided with a notch 271, and the eccentric shaft 261 and the eccentric shaft 231 are arranged in the notch 271. The notch 271 is provided with a groove block 272 with an area smaller than that of the notch 271. When the groove block 272 is rotated by the eccentric shaft 261, the groove block 272 can move along the inner wall of the notch 271 to rotate the eccentric shaft 231 in the through hole 273 and the lead screw 23. The groove block 272 is provided with the through hole 273 and the through hole 274, and the eccentric shaft 231 is arranged in the through hole 273 and the eccentric shaft 261 is arranged in the through hole 274. The eccentric shaft 231 and the through hole 273 and the eccentric shaft 261 and the through hole 274 are fastened.

[0047] When the motor 26 drives the eccentric shaft 231 to rotate, the eccentric shaft 231 drives the groove block 272 to move along the inner wall of the notch 271 to rotate the eccentric shaft 231 on both sides and the lead screw 23.

[0048] The clamping frame 28 is provided with a limiting sleeve 281 and a limiting sleeve 282, and the rightmost ends of the eccentric shaft 231 and the eccentric shaft 261 are arranged in the limiting sleeve 281 and the limiting sleeve 282, respectively. When the eccentric shaft 231 and the eccentric shaft 261 rotate, in order to ensure the stability of the rotation, the non-eccentric section of the outer end of the eccentric shaft 231 and the eccentric shaft 261 is further limited by the limiting sleeve 281 and the limiting sleeve 282 on the clamping frame 28, so as to improve the stability of the rotation of the eccentric shaft 231 and the eccentric shaft 261.

[0049] The lifting connecting frame 3 comprises a frame plate 31 and a limiting frame 32. One side of the frame plate 31 is provided with a side plate 313 perpendicular to the frame plate 31, and both sides of the side plate 313 are provided with sliding strips 311. The limiting frame 32 is vertically arranged on the bottom layer 12, and the sliding strips 311 are slidingly arranged in the limiting frame 32. The limiting frame 32 is used for guiding the up-down movement of the frame plate 31 to ensure the vertical movement of the frame plate 31. The bottom of both sides of the side plate 313 is further provided with a mounting plate 312 perpendicular to the side plate 313. The frame plate 31 is fixedly arranged at the bottom of the lifting layer 11, and the frame plate 31 is provided with a steering wheel 41 at the bottom. The bottom of the mounting plate 312 is provided with a driving wheel 42.

[0050] The driving device 4 is the power source of the whole device, which comprises the steering wheel 41 and the driving wheel 42, and can control the moving direction and speed of the water dispenser.

[0051] The steering wheel 41 includes a fixed sleeve 411, which is fixedly mounted on the bottom of the frame 31. The fixed sleeve 411 fixes and supports the internal structure of the steering wheel 41 and provides rotational support for the internal rotating sleeve 413. The rotating sleeve 413 is housed within the fixed sleeve 411. The rotating sleeve 413 can rotate under the drive of the second motor 412, thereby changing the direction of the wheel 1 415 at its bottom, thereby changing the forward direction of the water dispenser.

[0052] A circle of internal teeth 414 is provided on the inner side surface of the top of the rotating sleeve 413, and a second motor 412 is further provided inside the fixed sleeve 411. The second motor 412 is fixedly installed upside down on the bottom of the frame plate 31, that is, the position of the second motor 412 is fixed, and the second motor 412 is connected to the second motor 412. The driving teeth 416 are engaged with the internal teeth 414. A wheel 1 415 is provided at the bottom of the rotating sleeve 413. When the second motor 412 causes the driving teeth 416 to rotate, the internal teeth 414 are driven to drive the rotating sleeve 413 to rotate, thereby realizing the steering of the wheel 1 415 at the bottom of the rotating sleeve 413.

[0053] Drive wheel 42 includes a mounting bracket 422, which is fixedly mounted to the bottom of mounting plate 312. Motor 3 421 and wheel 2 423 are mounted on mounting bracket 422. Motor 3 421 and wheel 2 423 are connected by a transmission belt (not shown). Mounting bracket 422 is used to secure and support the internal structure of drive wheel 42. Motor 3 421 drives wheel 422 to rotate via the transmission belt.

[0054] The bottom layer 12 is provided with a first clearance opening 121 and a second clearance opening 122, which correspond to the steering wheel 41 and the driving wheel 42 respectively. The first clearance opening 121 and the second clearance opening 122 are used for the steering wheel 41 and the driving wheel 42 to extend downward from the bottom layer 12.

[0055] Working principle: in the use of the follow-up water dispenser, the initial state is that the water dispenser is in a static state, at this time the steering wheel 41 and the drive wheel 42 of the drive device 4 inside the shell are hidden inside the bottom layer 12, at this time the bottom layer 12 of the shell 1 is in contact with the ground, and the whole water dispenser is in a static state. When it is necessary to follow the pet and urge it to drink water, the motor 26 starts to operate, so that the eccentric shaft 261 drives the groove block 272 to make a circular motion along the inner wall of the groove 271, at this time the eccentric shaft 231 assembled in the through hole 273 at both ends of the groove block 272 also makes a circular motion, thereby rotating the lead screw 23, so that the sliding block 25 on the lead screw 23 gradually approaches the clamp bracket 27 from far to near. In the process that the sliding block 25 approaches the clamp bracket 27, the lifting rod 29 is pulled, so that one end of the lifting rod 29 in the sliding groove 222 of the sliding frame 22 moves downward, further making the top plate 21 vertically slidingly assembled on the top of the sliding frame 22 move downward under the weight of the lifting layer 11 and the water drinking device on the lifting layer 11. The distance between the lifting layer 11 and the bottom layer 12 becomes smaller, and the lifting connecting frame 3 also descends, so that the steering wheel 41 and the drive wheel 42 are pressed out of the bottom layer 12, thereby making the steering wheel 41 and the drive wheel 42 contact the ground, and the bottom layer 12 is away from the ground. After the steering wheel 41 and the drive wheel 42 contact the ground, for the steering wheel 41, the internal motor 412 operates, so that the rotating sleeve 413 rotates in the fixed sleeve 411, thereby changing the direction of the bottom wheel 415, and playing a steering role. For the drive wheel 42, the motor 421 drives the wheel 423 to rotate through the transmission belt, thereby playing a driving role. Thus, the effect of moving and following can continuously attract the attention of the pet, stimulate their interest in drinking water, and the pet does not need to find water sources everywhere to drink water, which is beneficial to the pet to supplement water in time.
