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

[0039] See also Figure 1-13 A pet drinking fountain comprises a shell 1, which serves as the main structure of the entire drinking fountain. The shell 1 plays the role of protecting and supporting the internal components. A bottom layer 12 is arranged at the bottom of the shell 1, and a lifting layer 11 is arranged in the middle of the inner part of the shell 1. A drinking device (not shown in the figure) is arranged on the lifting layer 11. The drinking device is a prior art, and the drinking device provides clean drinking water for pets. A lifting device 2 and a 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 drinking fountain and is the supporting foundation of the lifting layer 11 and the driving device 4. A lifting connection frame 3 is connected between the lifting device 2 and the driving device 4. The lifting connection frame 3 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 connection frame 3. The lifting connection frame 3 is arranged at the bottom of the lifting layer 11. The lifting device 2 allows the driving device 4 to be hidden inside the bottom layer 12 and remain stationary as a whole, or to extend out of the bottom layer 12 to contact the ground and drive the whole to move. When the water dispenser is stationary, the bottom layer 12 contacts the ground to provide stable support; when the water dispenser needs to be moved, the driving device 4 on the bottom layer 12 will extend and contact the ground to provide mobility.

[0040] The top of the housing 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 drinking water device inside the housing 1 will deliver drinking water from the water outlet 13 and store it in the water storage groove 14 for the pet to drink.

[0041] The lifting layer 11 is slidably assembled inside the housing 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 relatively far; when the water dispenser needs to be moved, the lifting device 2 will move the lifting connection frame 3 downward, that is, the distance between the lifting layer 11 and the bottom layer 12 becomes closer, so that the driving device 4 is extended from the first and second clearance openings 121 and 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 arranged 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 arranged 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 playing the role of lifting the top plate 21 therein, thereby realizing the up and down movement of the lifting connecting frame 3.

[0043] The clamp frame 1 27 and the clamp frame 2 28 are assembled with each other and fixedly arranged on the bottom layer 12. The clamp frame 1 27 is equipped with one end of two screw rods 23, and the other end of the screw rods 23 is installed with a bearing seat 24, and the bearing seat 24 is fixedly installed on the bottom layer 12. The clamp frame 1 27 and the clamp frame 2 28 are used to fix the screw rods 23 and the motor 1 26, and the two screw rods 23 are driven by one motor 1 26 to make the same movement.

[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 a 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 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, the top plate 21 on the sliding frame 22 will be pushed upward, thereby pushing the lifting connecting frame 3 upward, realizing the recovery and hiding of the driving device 4, so that the water dispenser is 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 water drinking device, thereby pushing the lifting connecting frame 3 downward and pushing the driving device 4 downward, so that the water dispenser can be moved.

[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 action of the lifting rod 29, and is about to push and pull the lifting connecting frame 3 up and down.

[0046] The clamping frame 27 is also equipped with a motor 26, and the motor 26 is provided with an eccentric shaft 261. The end of the screw rod 23 located in the clamping frame 27 is provided with an eccentric shaft 231. The clamping frame 27 is provided with a slot 271, and the eccentric shaft 261 and the eccentric shaft 231 are located in the slot 271. The slot 271 is equipped with a slot block 272 whose area is smaller than that of the slot 271. The slot block 272 has an area smaller than that of the slot 271 so that when the slot block 272 is driven to rotate by the eccentric shaft 261, the slot block 272 can fit the inner wall of the slot 271 inside the slot 271 to perform a certain circular motion, so that the through holes 273 at both ends of the slot block 272 can drive the eccentric shaft 231 therein to perform a circular motion, and finally drive the screw rod 23 to rotate. The slot block 272 is provided with a through hole 1 273 and a through hole 274 . The eccentric shaft 1 231 is assembled in the through hole 1 273 , and the eccentric shaft 261 is assembled in the through hole 274 . The eccentric shaft 1 231 and the through hole 1 273 as well as the eccentric shaft 2 261 and the through hole 2 274 are fastened together.

[0047] When the motor 26 drives the eccentric shaft 231 to rotate, the eccentric shaft 231 drives the slot block 272 to make a circular motion in the slot 271 to fit the inner wall of the slot 271, thereby driving the eccentric shaft 231 on both sides to make a circular motion and driving the screw rods 23 on both sides to rotate.

[0048] The clamp frame 28 is provided with a limiting sleeve 1 281 and a limiting sleeve 2 282, and the rightmost ends of the eccentric shaft 1 231 and the eccentric shaft 2 261 are respectively assembled in the limiting sleeve 1 281 and the limiting sleeve 2 282. When the eccentric shaft 1 231 and the eccentric shaft 2 261 rotate, in order to ensure their stability during rotation, the limiting sleeve 1 281 and the limiting sleeve 2 282 on the clamp frame 2 28 further limit the non-eccentric sections at the outer ends of the eccentric shaft 1 231 and the eccentric shaft 2 261, thereby improving the stability of the eccentric shaft 1 231 and the eccentric shaft 2 261 during rotation.

[0049] The lifting connection frame 3 includes a frame plate 31 and a limiting frame 32. A side plate 313 perpendicular to the frame plate 31 is provided on one side of the frame plate 31. Slide bars 311 are provided on both sides of the side plate 313. The limiting frame 32 is vertically arranged on the bottom layer 12, and the slide bars 311 are slidably arranged in the limiting frame 32. The limiting frame 32 is used to provide a guide for the up and down movement of the frame plate 31 to ensure its vertical up and down movement. The bottom of both sides of the side plate 313 is also 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. A steering wheel 41 is installed at the bottom of the frame plate 31, and a driving wheel 42 is installed at the bottom of the mounting plate 312.

[0050] The driving device 4 is the power source of the entire device, and includes a steering wheel 41 and a driving wheel 42, which 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 plate 31. The fixed sleeve 411 fixes and supports the internal structure of the steering wheel 41 and provides rotation support for the internal rotating sleeve 413. The rotating sleeve 413 is combined with the rotating sleeve 413 inside the fixed sleeve 411. The rotating sleeve 413 can rotate under the drive of the motor 2 412, thereby changing the direction of the wheel 1 415 at the bottom thereof, thereby realizing the change of the forward direction of the water dispenser.

[0052] A circle of inner teeth 414 is provided on the inner side surface of the top of the rotating sleeve 413, and a second motor 412 is also provided inside the fixed sleeve 411. The second motor 412 is inverted and fixedly installed at 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 meshed with the inner 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 inner 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] The driving wheel 42 includes a mounting frame 422, which is fixedly mounted on the bottom of the mounting plate 312. A motor 3 421 and a wheel 2 423 are mounted on the mounting frame 422. The motor 3 421 and the wheel 2 423 are connected by a transmission belt (not shown in the figure). The mounting frame 422 is used to fix and support the internal structure of the driving wheel 42. The motor 3 421 drives the wheel 2 423 to rotate through 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: When the follow-up water dispenser is used, the initial state is that the water dispenser is in a stationary state. At this time, the steering wheel 41 and the driving wheel 42 of the driving 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 entire water dispenser is in a stationary state. When it is necessary to follow the pet and urge it to drink water, the motor 26 starts to run, so that the eccentric shaft 261 drives the groove block 272 to make a circular motion in the groove 271 to fit the inner wall of the groove 271. At this time, the eccentric shaft 231 installed in the through hole 273 at both ends of the groove block 272 will also make a circular motion, thereby driving the screw rod 23 to rotate, so that the slider 25 on the screw rod 23 gradually approaches the clamping frame 27 from far to near. In the process of the slider 25 approaching the clamping frame 27, the lifting rod 29 is pulled so that the lifting rod 29 is in the position. One end of the slide groove 222 of the sliding frame 22 moves downward, further making the top plate 21 vertically slidably mounted on the top of the sliding frame 22 move downward under the weight of the upper lifting layer 11 and the drinking water device on the lifting layer 11, the lifting layer 11 descends, the distance between the lifting layer 11 and the bottom layer 12 becomes smaller, and the lifting connection frame 3 also descends accordingly, the frame plate 31 and the mounting plate 312 press the steering wheel 41 and the driving wheel 42 out of the bottom layer 12, so that the steering wheel 41 and the driving wheel 42 contact the ground, and the bottom layer 12 is away from the ground. After the steering wheel 41 and the driving wheel 42 contact the ground, for the steering wheel 41, the internal motor 2 412 runs, so that the rotating sleeve 413 rotates inside the fixed sleeve 411, thereby changing the direction of the bottom wheel 1 415, which plays a steering role. For the driving wheel 42, the motor 3 421 drives the wheel 2 423 to rotate through the transmission belt, thereby playing a driving role. Thereby, the mobile following can continuously attract the attention of pets, stimulate their interest in drinking water, and the pets do not need to look for water sources everywhere to drink water, which is conducive to the pets replenishing water in time.
