[0038] This utility model proposes a pet water dispenser.

[0039] Please see Figures 1 to 9 In one embodiment of this utility model, the pet water fountain includes:

[0040] The housing 100 includes a drinking groove 11 formed on the upper end face of the housing 100, and the drinking groove 11 has a water outlet 111 and a water return outlet 112.

[0041] The water storage tank 200 has a water storage space 21, which is formed by a foldable tank wall 22 and a bottom plate 23. The water outlet 111 and the water return 112 are both connected to the water storage space 21. The shell 100 is fitted around the outer periphery of the foldable tank wall 22. The foldable tank wall 22 has at least two annular creases 221 that fold the shell 100 toward the bottom plate 23. The water storage tank 200 has a folded state and a working state. In the folded state, the foldable tank wall 22 is bent at the annular creases 221 and the bottom plate 23 is close to the shell 100. In the working state, the foldable tank wall 22 is unfolded and the bottom plate 23 is far away from the shell 100.

[0042] The filter assembly 300 includes a filter box 31 and an ultrafiltration filter element 32 disposed in the filter box 31. In use, the filter box 31 is installed on the lower end face of the housing 100 and is set corresponding to the return water port 112.

[0043] The technical solution of this utility model, by setting up a foldable water storage tank 200, reduces the volume occupied by the pet water fountain during transportation or travel. This makes it easier for users to carry when out and about, or for businesses to use smaller packaging boxes, thus reducing logistics waste and achieving energy conservation and environmental protection. When in use, unfolding the folded water storage tank 200 allows users to fill it with a larger amount of water. During extended outings, this reduces the probability of pets developing illnesses due to dehydration, as well as the probability of pets drinking rainwater or tap water directly due to dehydration. It also avoids the cumbersome process of users rehydrating their pets with water bottles when out. The filter component 300 helps maintain the cleanliness of the water stored in the water storage tank 200.

[0044] In one embodiment, the ultrafiltration filter element 32 includes a multi-layer planar ultrafiltration membrane. When water flows into the filter box 31 from the return port 112, it passes through the multi-layer planar ultrafiltration membrane, effectively removing bacteria, impurities, and harmful substances from the water. This provides pets with clean and healthy drinking water, reducing the risk of illness from drinking unclean water, and promoting the pet's health and growth. Furthermore, the multi-layer planar ultrafiltration membrane offers better filtration and a larger filtration area, ensuring a sufficient supply of clean water for the pet. In other embodiments, the ultrafiltration filter element 32 may include other ultrafiltration (US) filter media.

[0045] In one embodiment, the vertical cross-sectional shape of the drinking groove 11 is configured as a concave arc, and the water return port 112 is located near the side wall of the housing 100. That is, the water return port 112 is located higher than the lowest point of the drinking groove 11. The water in the drinking groove 11 is stored between the bottom end of the drinking groove 11 and the water return port 112. The concave arc shape conforms to the contact method of the pet's mouth and tongue, allowing the pet's mouth to naturally fit the edge of the groove when drinking, making it convenient for its tongue to enter the groove to lick the water. This reduces the difficulty of drinking for the pet, making drinking smoother and more natural, conforming to the pet's instinctive daily drinking behavior, and improving the convenience and comfort of drinking for the pet. By positioning the water return outlet 112 near the side wall of the housing 100, it effectively prevents the pet from directly contacting the water return outlet 112 while drinking. This ensures that the pet's drinking process is not affected by the water return outlet 112, allowing it to focus on the water in the drinking groove 11, improving drinking comfort and safety, and preventing the pet from accidentally touching the water return outlet 112, which could cause abnormal water flow or affect the normal operation of the water fountain. In other embodiments, the vertical cross-section of the drinking groove 11 can be a square with an opening on the top.

[0046] In one embodiment, the water outlet 111 is located near the side wall of the housing 100 and is positioned opposite the water return outlet 112. Water flows directly from the water outlet 111 to the water return outlet 112, forming an efficient water circulation path, accelerating the water flow speed, reducing the residence time of water in the drinking groove 11, and preventing water quality deterioration. In other embodiments, the water outlet 111 may be located at the lowest point of the drinking groove 11.

[0047] In one embodiment, the filter box 31 has an overflow port 312 at one end near the housing 100, and the overflow port 312 is located above the ultrafiltration filter element 32. When the water flow in the drinking groove 11 of the outlet 111 is too large, such that the filtration speed of the filter structure at the return port 112 is lower than the water flow rate of the outlet 111, the overflow port 312 can directly discharge the excess water in the filter box 31 into the water storage space 21, preventing excessive water accumulation in the drinking groove 11 from overflowing. Further, the filter box 31 includes an inlet filter port 314 and an outlet filter port 315 arranged opposite each other in its height direction, the ultrafiltration filter element 32 is located between the inlet filter port 314 and the outlet filter port 315, the filter box 31 includes a filter cover plate 313, the inlet filter port 314 is formed in the filter cover plate 313, and the overflow port is located on the upper side of the filter cover plate 313. That is, the filter cover 313 and the peripheral and bottom walls of the filter box 31 enclose the filter space 316, and the ultrafiltration filter element 32 is located in the filter space 316. In other embodiments, the overflow outlet 312 may not be provided.

[0048] In one embodiment, the pet water fountain further includes a pumping assembly 400, which includes a water pump 41 and a connecting hose 42. One end of the connecting hose 42 is connected to the pumping port 411 of the water pump 41, and the other end is detachably connected to the water outlet 111. In use, the water pump 41 is located inside the water storage tank 200. The lower end face of the housing 100 is provided with a mounting bracket 12 extending away from the drinking groove 11. The mounting bracket 12 is circumferentially arranged around the return water inlet 112, and the filter box 31 is detachably connected to the mounting bracket 12. It should be noted that when the water storage tank 200 is in a folded state, that is, when the user goes out to store and carry it, or when the merchant packs it, the pumping assembly 400 is detached from the housing 100 and stored separately. When the user needs to use the pet water fountain, the user installs the pumping assembly 400 onto the housing 100, that is, connects the connecting hose 42 to the water outlet 111. Furthermore, when the water storage tank 200 is in a folded state, the filter assembly 300 also needs to be disassembled from the housing 100 and then reinstalled on the housing 100 when in use. The lower end face of the housing 100 has a mounting tube 14 that communicates with the water outlet 111 and extends downwards. The connecting hose 42 is interference-fitted onto the mounting tube 14. The filter box 31 is connected to the mounting bracket 12 via a snap-fit ​​connection. Specifically, the mounting bracket 12 has multiple snap-fit ​​holes 13, and the upper end of the filter box 31 has corresponding multiple snap-fit ​​protrusions 311 to snap into the snap-fit ​​holes 13. In other embodiments, the housing 100 may not have a mounting bracket 12.

[0049] In one embodiment, the pet water fountain further includes a sensing component 500, which includes a sensing housing 51 disposed on the upper surface of the housing 100 and a sensing sensor 52 disposed within the sensing housing 51. The sensing sensor 52 is positioned towards the drinking groove 11 and is electrically connected to the pumping component 400. Because the sensing sensor 52 is positioned towards the drinking groove 11, it can quickly sense when a pet approaches and trigger water to flow from the water outlet 111, eliminating the need for manual operation by the pet owner and providing an automatic and convenient drinking experience for the pet, meeting the pet's need for water at any time. The sensing component 500 only activates the pumping component 400 to dispense water when it senses a pet approaching, avoiding water waste caused by continuous water dispensing for extended periods and reducing the water fountain's energy consumption, achieving water and energy conservation. By controlling water dispensing through sensing, direct contact between the pet and the water fountain is reduced, lowering the risk of bacterial contamination from pet contact with the water outlet 111, helping to maintain the cleanliness of the water fountain and the hygiene of the drinking water, which is beneficial to the pet's health. In other embodiments, the water pump 41 in the pumping assembly 400 may be located inside the sensing housing 51, with one end of the connecting hose 42 connected to the water pump 41 and the other end extending into the water storage space 21 to draw water from the water storage space 21 to the water pump 41. The water outlet 111 is located on the drinking groove 11 near the side wall of the sensing housing 51 and communicates with the pumping port 411 of the water pump 41. In another embodiment, the sensing assembly 500 may not be provided.

[0050] In one embodiment, the sensor housing 51 and the drinking groove 11 are spaced apart on the upper surface of the housing 100. The sensor housing 51 is installed at a certain distance from the drinking groove 11 to prevent accidental activation of the sensor when the pet moves around in a small area near the drinking groove 11 (e.g., its head enters the drinking groove 11 and then moves away, but its body remains near the drinking groove 11). This avoids unnecessary continuous water dispensing, reduces the water dispenser's power consumption, and extends its lifespan. Furthermore, it prevents direct contact or damage to the sensor housing 51 when cleaning the drinking groove 11, reducing cleaning difficulty and maintenance costs. It also prevents water from entering the sensor housing 51 during cleaning, thus preventing damage to delicate components such as the sensor 52. In other embodiments, the sensor housing 51 may be located in the middle of the drinking groove 11.

[0051] In one embodiment, the sensing sensor 52 includes an infrared sensor 53. The infrared sensor 53 is technologically mature and has stable performance. It can still work stably in complex environments (such as environments with a lot of pet hair and debris) and is not easily interfered with, ensuring the normal operation of the water dispenser and the accurate triggering of the water dispensing function. Furthermore, the infrared sensor 53 is relatively common in the market, inexpensive, and easy to obtain and replace, reducing the production and maintenance costs of the pet water dispenser. In addition, the infrared sensor 53 is small in size, making it easy to integrate into the housing 100 of the pet water dispenser without taking up too much space or affecting the overall appearance design of the water dispenser, thus maintaining its functionality while possessing good aesthetics and practicality. In other embodiments, it can also be a photoelectric sensor, etc.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
