Description

Technical Field

[0001] This invention relates to the field of pet water fountains, and more specifically to a drainage structure for a pet water fountain. Background Technology

[0002] Existing pet water fountains typically draw water from the tank into the drinking dish, with the water exiting from the center of the dish. As the water accumulates, it drains through a drain at the edge. Because water naturally flows in a straight line along the path of least resistance towards the nearest drain, the large area between the center and edge of the dish experiences slow or even stagnant water flow. This prevents the effective flushing away of saliva, food scraps, and shed hair, leading to the accumulation of bacteria and biofilm in these dead zones. Furthermore, to ensure water overflows to the drain, the water dish often needs to maintain a deep water level. This not only increases the risk of the pet getting their chin wet and choking, but also results in incomplete water turnover, leaving the surface water in a state of "false circulation," significantly reducing the actual filtration and purification effect.

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] The preferred embodiments of the present invention will now be further described with reference to the accompanying drawings. Figures 1 to 7As shown, the drainage structure of the pet water fountain includes a first housing 100, a water tray assembly 200 on the top of the first housing 100, a cover 210, a tray 220 formed on the top of the cover 210, a downwardly extending receiving tube 230 inside the cover 210, a drain outlet 221 formed at the bottom of the tray 220 by the receiving tube 230, a second housing 300 at the bottom of the first housing 100, the receiving tube 230 passing through the first housing 100 and communicating with the second housing 300, a sealing component 400 covering the drain outlet 221, a lifting device 500 capable of driving the sealing component 400 to move up and down inside the receiving tube 230, and a drainage channel 600 formed between the lifting device 500 and the receiving tube 230.

[0023] This application is mainly used in pet water fountains. Its purpose is to better drain the water in the water bowl into the wastewater tank. In the working state of this application, the cover 210 of the water bowl assembly 200 covers the top of the first box 100, and the first box 100 covers the top of the second box 300. The receiving tube 230 passes through the first box 100 and communicates with the second box 300. In specific implementation, the first box 100 is used to hold clean water, and then the clean water is drawn into the bowl 220 by the water pumping mechanism in the cover 210. Under normal conditions, since the shape of the bowl 220 is concave and the drain outlet 221 at the bottom of the bowl 220 is blocked by the sealing component 400, the clean water is left in the bowl 220 for the pet to drink.

[0024] When the clean water in the pan 220 accumulates a large amount of pet hair, food scraps, or dust due to prolonged retention, and drainage is required, the lifting device 500 is activated to raise the sealing component 400, freeing it from blocking the drain outlet 221. At this time, the water in the pan 220 can flow from the drain outlet 221 into the drainage channel 600 between the lifting device 500 and the receiving pipe 230, and finally into the second box 300, thus completing the discharge of wastewater from the pan 220.

[0025] Compared with the prior art, this application achieves better drainage effect by drawing clean water from the first tank 100 into the tray 220, sealing the drain outlet 221 with the sealing component 400, and then controlling the lifting and lowering of the sealing component 400 through the lifting device 500 to allow the sewage to be discharged into the second tank 300. This achieves separation of clean and dirty water while also achieving better drainage effect.

[0026] In a further embodiment described above, the first housing 100 is annular in shape, with its inner ring fitting onto the outer wall of the receiving tube 230. A drainage trough 231 communicating with the second housing 300 is provided at the bottom of the receiving tube 230. This ensures that water between the first housing 100 and the interior of the receiving tube 230 is undisturbed, and wastewater from the drainage channel 600 can flow into the second housing 300 through the drainage trough 231.

[0027] Further, based on the above embodiments, a through groove 110 is provided on the top of the first housing 100, and an electrically connected water pump 211, a first control circuit board 212 and a battery pack 213 are provided inside the cover 210. A water pump pipe 214 is provided at the bottom of the cover 210. One end of the water pump pipe 214 extends into the first water tank through the through groove 110, and the other end is connected to the water pump 211. The water pump 211 is connected to a water outlet pipe 215, and the water outlet pipe 215 forms a water outlet 222 on the edge of the plate 220. When it is necessary to pump clean water from the first water tank into the dish 220, the water pump 211 is started to pump the water from the first water tank into the water pump 211 through the water pump pipe 214, and then into the dish 220 through the water outlet pipe 215 and the water outlet 222. Since the dish 220 is concave and the water outlet 222 is located on the edge of the dish 220, the water will flow to the bottom of the dish 220 due to gravity. Since the drain outlet 221 at the bottom of the dish 220 is covered by the sealing component 400, the clean water is left in the dish 220 for the pet to drink.

[0028] Further, based on the above embodiments, the lifting device 500 includes a drive assembly 510 and a lifting assembly 520 arranged axially along the receiving tube 230. The drive assembly 510 is supported within the receiving tube 230. The drive assembly 510 includes a first tube body 511, in which a rotary motor 512 is disposed. A rotor 513 is sleeved on the rotary motor 512. A threaded protrusion 513a is provided on the outer wall of the rotor 513. The lifting assembly 520 includes a second tube body 521, in which a stator ring 522 is fixed. The rotor 513 is inserted into the stator ring 522. A threaded groove 522b that can cooperate with the threaded protrusion 513a is provided on the inner wall of the stator ring 522. A waterproof ring wall 530 is provided between the first tube body 511 and the second tube body 521. The waterproof ring wall 530 surrounds the rotor 513 and the stator ring 522. When the sealing component 400 needs to be driven to rise or fall, the rotary motor 512 is started to drive the rotor 513 to rotate. Since the rotor 513 and the stator ring 522 are connected by a helical connection, when the rotor 513 rotates, the stator ring 522 will move up and down on the rotor 513, thereby driving the lifting component 520 to move up and down.

[0029] Further, based on the above embodiments, the waterproof annular wall 530 includes an annular wall body 531 and a downwardly extending extension 532. An annular groove 514 is provided at the top of the first tube 511. The top of the annular wall body 531 is sleeved and fixed on the second tube 521. The extension 532 is inserted into the annular groove 514 to form an interference fit. Thus, when the rotary motor 512 starts rotating, the second tube moves upward through the cooperation of the rotor 513 and the stator ring 522. Since the extension is always inserted into the annular groove 514, the water in the drainage channel 600 is blocked by the waterproof annular wall 530, preventing it from entering the drive assembly 510 and thus affecting the operation of the rotary motor 512. In addition, it should be noted that the waterproof annular wall 530 serves to connect the drive assembly 510 and the lifting assembly 520, allowing the drive assembly 510 and the lifting assembly 520 to be assembled as a single module.

[0030] Furthermore, based on the above embodiment, the waterproof ring wall 530 is made of waterproof adhesive, and the length of the extension portion 532 is greater than the axial length of the stator ring 522. Thus, regardless of the rotation between the rotor 513 and the stator ring 522, the extension portion 532 remains inserted within the ring groove 514, thereby further ensuring the waterproof effect of the waterproof ring wall 530.

[0031] Furthermore, based on the above embodiments, a plurality of guide posts 523 are provided inside the second tube 521, and a plurality of guide slots 515 are provided inside the first tube 511 for the guide posts 523 to insert into. When the second tube 521 is raised or lowered relative to the first tube 511, the guide posts 523 are inserted into the guide slots 515, thereby better guiding the raising and lowering of the lifting assembly 520.

[0032] Further, based on the above embodiments, a support plate 232 is provided inside the receiving tube 230, the driving assembly 510 is placed on the support plate 232, a connecting plate 233 is provided between the support plate 232 and the receiving tube 230, a plurality of first electrical contacts 234 are provided on the top of the support plate 232, the first electrical contacts 234 are electrically connected to the first control circuit board 212, a second control circuit board 516 is provided inside the first tube body (511), the second control circuit board 516 is electrically connected to the rotary motor 512, and a second electrical contact 517 is provided on the second control circuit board 516 opposite to the position of the first electrical contacts 234. When installing the lifting device 500 onto the receiving tube 230, it is only necessary to insert the lifting device 500 along the axial direction of the receiving tube 230 so that its second electrical contact 517 and the first electrical contact 234 come into contact with each other to energize the rotary motor 512. No additional wiring is required in the narrow space of the receiving tube 230.

[0033] Furthermore, based on the above embodiment, the sealing component 400 is annular in shape and sleeved on the end of the second pipe body 521 away from the first pipe body 511. A sealing ring 410 is provided at the bottom of the sealing component 400, and the sealing ring 410 is sleeved on the second pipe body 521. Thus, under normal conditions, when the sealing component 400 covers the drain outlet 221, the sealing ring 410 and the second pipe body 521 cooperate to seal the drain outlet 221. When drainage is required, the second pipe body 521 drives the sealing ring 410 to rise, causing it to detach from the drain outlet 221, thereby allowing water in the tray 220 to enter the second box 300 through the drainage channel 600.

[0034] The details of the exemplary embodiments described above are provided, and the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention.
