[0002] As people's living standards improve, more and more people are keeping pets. Pets not only make people's lives healthier and more fulfilling, but also bring them joy and cultivate their sense of responsibility, thus becoming an important part of life. With the development of electronic products, pet living equipment has also developed positively, such as electric litter boxes, electric feeders, or electric water fountains. Among them, electric water fountains are reasonably priced and can encourage pets to drink more water and ensure the quality of pet drinking water, making them a widely recognized and purchased product by users.

[0003] In the prior art, such as the utility model patent with Chinese patent number 202322847772.6, a dual-outlet pet water fountain is disclosed. In this design, a water channel is provided between the cover plate and the water-holding plate. When water overflows from the water-holding groove, it flows from the water channel onto the cover plate, then into the filter tank, and finally into the water tank from the drain of the filter tank. The filtration system constructed by the aforementioned structure is widely used in the prior art. However, in actual use, it has been found that the filtration effect of the filtration system is not good. Due to the characteristics of pet water fountains, the water flow velocity generated by the water pump is relatively small. When water overflows from the groove, more of it flows back into the water tank through the inner wall of the filter tank. Therefore, this part of the water flow cannot play a proper filtration role and cannot guarantee the cleanliness of the pet's drinking water, posing a significant risk to the pet's health. Therefore, there should be a pet water fountain with a more reasonable structure to solve the shortcomings of the prior art. Utility Model Content

[0042] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0043] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0044] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0045] To address the aforementioned technical problems, this application provides an improved pet water fountain with a filtration system. Please refer to the appendix. Figure 1 To be continued Figure 12 The system includes a water storage body 1, a drinking tray 11, a filter cartridge 5, and a water outlet assembly 2. The water storage body 1 has a water storage cavity 12, which houses a water pump assembly 3. The drinking tray 11 is detachably fitted to the opening of the water storage body 1 and has a first return water hole 113. The filter cartridge 5 is placed inside the water storage body 1 and together with the drinking tray, forms a buffer cavity E. The filter cartridge 5 has a settling groove 51 corresponding to the position of the first return water hole 113, and a filter cartridge module 4 is detachably connected inside the settling groove 51. The inner wall of the settling groove 51 also has a second return water hole 53. The first part of the water outlet assembly 2 is connected to the water pump assembly 3, and the second part forms a water outlet 21 on the surface of the drinking tray 11.

[0046] The following is a further explanation of this solution in specific usage: Drinking water is stored in the water storage body. The water pump assembly 3 and the water outlet assembly 2 work together to pump water from the water storage body 1 to the surface of the drinking tray 11, allowing pets to drink immediately from this area. Pets' eating habits include short intervals between eating wet food and dry food and drinking water, and they also experience shedding due to metabolism. Therefore, the drinking tray 11 may contain hair, food residue, and other impurities. A filtration system composed of the first return water hole 113, the filter module 4, and the second return water hole 53 circulates and filters the drinking water located between the drinking trays 11. The filter module 4 adsorbs and filters impurities, ensuring the cleanliness of the drinking water and the health of the pets. Thus, through the cooperation of the filter tray 5 and the drinking tray 11, drinking water sequentially passes through the first return water hole 113, the filter module 4, and the second return water hole 53 before returning to the interior of the water storage body 1, achieving filtration circulation and ensuring the filtration efficiency and cleanliness of the drinking water.

[0047] For the detachable solution of the drinking tray 11 and filter tray 5, a magnetic suction structure, a snap-fit ​​structure, a threaded structure, or a plug-in structure can be used to achieve the detachable solution. In this embodiment, the edge of the water storage body 1 is formed with a connecting first step 14 and second step 15. The first step 14 is used to support the edge of the drinking tray 11, and the second step 15 is used to support the edge of the filter tray 5. The first step 14 and the second step 15 support the filter tray 5 and the drinking tray 11 respectively. This structural solution is inexpensive and ensures the convenience of disassembly and installation, making it easy for users to clean and maintain. Preferably, the drinking tray 11 and the filter tray 5 are assembled with the first step 14 and the second step 15 to form a buffer cavity. As the service life of the filter module extends, it will cause aging and blockage, or large impurities will be generated on the surface of the filter module and not cleaned in time, which will cause the filtration flow of drinking water to decrease. The buffer cavity can buffer the drinking water to be filtered, effectively preventing excessive accumulation of drinking water from overflowing directly from the drinking tray 11.

[0048] For the detachable connection between the filter disc 5 and the filter module 4, a detachable solution can also be achieved through a magnetic structure, a snap-fit ​​structure, a threaded structure, or a plug-in structure. In this embodiment, the outer wall of the filter module 4 and the inner wall of the settling tank 41 are respectively provided with a slot 41 and a snap-fit ​​protrusion 52. It is worth understanding that the filter module includes a filter cartridge and a frame box. The frame box covers and accommodates the filter cartridge. The outer wall of the frame box has snap-fit ​​protrusions 52. The snap-fit ​​protrusions 52 and the slot 41 are used to stably and securely assemble the filter module 4 in the settling tank 41. The frame box prevents the filter cartridge from expanding when it comes into contact with water, thereby preventing the filter cartridge from floating in the drinking water to be filtered.

[0049] In a further design, the inner wall of the settling tank is fitted to the outer wall of the filter module, and the resulting fitting surface is an undulating curved surface; the curved surface can provide a larger base area, ensuring the stable assembly of the filter module 4.

[0050] In this embodiment, the first return water hole 113 and the second return water hole 53 are both located within the filtration area formed by the axial cross section of the filter module. Under this design, when the drinking water to be filtered is at the expected flow rate, it can be guaranteed that 100% of the water enters the filter module 4 through the first return water hole 113 for filtration, and then exits through the filter module 4 and enters the interior of the water storage body through the second return water hole 53.

[0051] In this embodiment, the filter disc 5 is provided with a second clearance hole 54, and the drinking tray 11 is provided with a first clearance hole 114. The second part of the water outlet component 2 passes through the second clearance hole 54 and the first clearance hole 114 to form a water outlet 21 on the surface of the drinking tray 11. The second clearance hole 54 and the first clearance hole 114 are used to realize a detachable solution for the water outlet component 2. When the pet water fountain needs to be cleaned, the user can pull out the water outlet component from the second clearance hole 54 and the first clearance hole 114, thereby cleaning the water storage body 1, the drinking tray 11, and the filter disc 5. Non-electronic components are cleaned; in a further embodiment, the second clearance hole 54 and the profile of the water outlet assembly 2 form a return water gap H; the return water gap H allows the buffer chamber E and the water storage chamber 12 of the water storage body 1 to be interconnected; since the filter module 4 of this application is used extensively, the probability of the filter module 4 being blocked is also high. When there is a blockage and it is not dealt with in time, the overflow water in the buffer chamber E flows directly back to the water storage chamber 12 through the return water gap H, which further improves the overflow situation caused by the poor filtration flow of the filter module 4.

[0052] In this embodiment, a protrusion 112 is formed on the surface of the drinking tray 11, and a first return water hole 113 is formed on the surface of the protrusion 112. The protrusion 113 forms a main buffer space G in the buffer cavity. The main buffer space G can cooperate with the buffer cavity E to increase the water treatment capacity of drinking water when the filter module 4 is blocked, and further alleviate the situation of drinking water overflow.

[0053] In this embodiment, the protrusion forms a first drinking area and a second drinking area on the surface of the drinking tray. The central part of both the first and second drinking areas is concave, and the two concave surfaces are inclined around the protrusion so that the drinking water is guided to the first return water hole. The concave surface D and the protrusion 112 can enhance the water holding capacity of the first drinking area A and the second drinking area B, and form two drinking areas that can be used by two pets to drink water at the same time, reducing waiting time. The concave surface D is inclined at a predetermined angle, which can be 5-10°, so that the drinking water with a deeper liquid level in the concave surface D is guided to the first return water hole 113, filtered, and then returned to the water storage chamber 11 to achieve water circulation, resulting in a better circulation effect.

[0054] In this embodiment, the second part of the water outlet component 2 spans the two opposite edges of the drinking dish 11 and forms a gap with the protrusion 112; the water outlet 21 is located on both sides of the center of the second part to replenish water to the first drinking area A and the second drinking area B; the water outlet component 2 visually separates the drinking areas of the drinking dish 11, making it convenient for two pets to drink in the two drinking areas; the pets can distinguish the spatial layout of the drinking dish 11, avoiding drinking in the same direction, and making full use of the advantages of the dual drinking areas.

[0055] To simultaneously replenish water to the first drinking area A and the second drinking area B, reducing the pet's waiting time, two water outlets 21 are provided, one for each area. Therefore, this embodiment also includes a diverter head 22, located within the second part of the water outlet assembly 2, with a pre-set opening on its outer wall forming the water outlet 21. The inlet of the diverter head 22 is connected to the water pump assembly 3 via a pipe. It is easy to understand that the end of the pipe 31 furthest from the diverter head 22 can serve as one of the components in the first part of the water outlet assembly 2. The water pump assembly 3 can transport and circulate drinking water through the pipe and the diverter head. In a further embodiment, the water flow formed by the water outlet 21 is precisely located on the concave surface D of the first drinking area A and the second drinking area B, facilitating rapid accumulation of drinking water to a depth suitable for pet drinking.

[0056] As an improvement of this application, the outer wall of the water storage body 1 is provided with a strip window, and the two ends of the strip window show the bottom of the water pump assembly 3 and the filter cartridge 5 respectively. As a premise, the design of the settling tank 51 will create a profile protrusion on the back of the filter cartridge 5, which can make the profile wall thickness of the filter cartridge 5 lighter and achieve a larger water storage capacity. With this design, the length of the strip window 13 can facilitate the user to observe the working status of the water pump 31 and the filter cartridge module 4, such as the water pump is working, and the filter cartridge module 4 has poor water filtration capacity due to the service life.

[0057] Existing water dispensers are equipped with sensors to control water dispensing. In an embodiment that adds sensors, the circuit control scheme is as follows: It further includes a first PCB board 23 and a second PCB board 24 located within the second part of the water dispensing assembly 2 and electrically connected. The first PCB board 23 is electrically connected to the battery assembly 26 located within the first part of the water dispensing assembly 2, and a charging port is formed at one end of the second part of the water dispensing assembly 2. Sensors 26 are formed on both sides of the other end of the second part of the water dispensing assembly on the second PCB board 24. A hand area F is formed between the sensor 26 and the water outlet, facilitating user access. The water pump assembly is designed for easy handling and removal, facilitating subsequent cleaning and maintenance. When the sensor 26 detects a pet nearby, the first PCB board 23 and the second PCB board 24 work together to control the water pump assembly 3 to generate water flow, providing the pet with sufficient drinking water. The battery assembly can be placed anywhere by the user, offering greater flexibility. Under circuit control, the sensor 26 only activates the corresponding water outlet when a pet is detected, thus avoiding prolonged operation of the water pump assembly, saving battery power, achieving longer battery life, and avoiding frequent charging.

[0058] The advantages of this utility model are:

[0059] With the cooperation of the filter cartridge and the drinking water tray, drinking water can pass through the first return water hole, the filter cartridge module, and the second return water hole in sequence before returning to the interior of the water storage body to achieve filtration and circulation, thus ensuring the filtration efficiency and cleanliness of the drinking water.

[0060] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
