In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] Please see Figure 1 and Figure 2The pet water fountain provided by the present invention will now be described. The pet water fountain includes: a water tank 1, in which a first liquid storage chamber 121 is provided; a drinking tray 2, which is disposed on the water tank 1 and includes a base 21 and a side plate 22, forming a second liquid storage chamber 23 between the base 21 and the side plate 22; a water pump assembly 4, used to transport water in the first liquid storage chamber 121 to the second liquid storage chamber 23; and a filter assembly 3, which includes a mounting bracket 31, a first filter element 32 and a second filter element 33. The mounting bracket 31 is disposed on the drinking tray 2 or the water tank 1 and has a mounting cavity (not shown in the figure), which connects the first liquid storage chamber 121 and the second liquid storage chamber 23; the first filter element 32 and the second filter element 33 are located in the mounting cavity, and the water in the second liquid storage chamber 23 flows into the first liquid storage chamber 121 after being filtered by the first filter element 32 and the second filter element 33 in the mounting cavity.

[0036] In specific implementation, the water pump assembly 4 can be located inside or outside the water storage tank 1. When the water pump assembly 4 is located inside the water storage tank 1, it can be located at the bottom or on the side wall of the water storage tank 1, as long as the water pump assembly 4 can transport water from the first liquid storage chamber 121 to the second liquid storage chamber 23. Those skilled in the art can choose the appropriate configuration based on actual needs. The first filter element 32 and the second filter element 33 can have the same structure, for example, both the first filter element 32 and the second filter element 33 can be filter screen structures or filter element structures, or they can have different structures, for example, the first filter element 32 can be a filter screen and the second filter element 33 can be a filter element. The mounting bracket 31 can be located on the drinking tray 2 or on the water storage tank 1, as long as it enables the mounting cavity to connect the first liquid storage chamber 121 and the second liquid storage chamber 23 and allows water in the second liquid storage chamber 23 to flow back to the first liquid storage chamber 121. Those skilled in the art can choose the appropriate configuration based on actual needs.

[0037] Specifically, the first liquid storage chamber 121 contains clean water, and the water pump assembly 4 transports the water in the first liquid storage chamber 121 of the water tank 1 to the second liquid storage chamber 23 of the drinking tray 2 for the pet to drink; at the same time, the water in the second liquid storage chamber 23 flows into the installation cavity connected to the second liquid storage chamber 23, and the first filter element 32 and the second filter element 33 located in the installation cavity filter the water in sequence, and the filtered water flows into the first liquid storage chamber 121 connected to the installation cavity.

[0038] Compared with the prior art, the pet water fountain provided by this invention has a water pump assembly 4 that can transport water in the first storage chamber 121 to the second storage chamber 23. The water in the second storage chamber 23 can flow back to the first storage chamber 121 through the installation cavity that communicates with the first and second storage chambers 121 and 23, so that the water circulates in the first storage chamber 121, the second storage chamber 23 and the installation cavity, which meets the pet's habit of drinking flowing water. At the same time, since the first filter element 32 and the second filter element 33 are located in the installation cavity, they can perform double purification on the water entering the installation cavity, thereby ensuring that the water the pet drinks is always clean water and avoiding the situation where the pet drinks unclean water and it affects the pet's health.

[0039] In one embodiment, in conjunction with reference to Figure 3 and Figure 5 The chassis 21 has a through hole 211. The mounting bracket 31 includes a first end 312 and a second end 313, which are located inside the water storage tank 1. The second end 313 is detachably mounted to the through hole 211. The mounting bracket 31 can be a one-piece molded part. In specific implementations, the shape of the through hole 211 is not limited. The through hole 211 can be a square hole, a triangular hole, or a round hole. Those skilled in the art can select the appropriate shape of the through hole 211 according to the specific shape of the mounting bracket. Preferably, the through hole 211 is located in the central area of ​​the chassis 21. When the filter assembly 3 malfunctions, or when the first filter element 32 and / or the second filter element 33 are clogged by pet hair or dirt, the mounting bracket 31 can be removed from the through hole 211 to facilitate cleaning, repair, or replacement of the first filter element 32 and / or the second filter element 33 inside the mounting bracket 31. At the same time, when the water level in the first liquid storage chamber 121 of the water storage tank 1 is insufficient and water needs to be added, the mounting bracket 31 can be removed from the through hole 211 to facilitate the user to add water to the first liquid storage chamber 121 of the water storage tank 1 through the through hole 211.

[0040] In one embodiment, in conjunction with reference to Figure 3 The chassis 21 has a boss 24 surrounding the through hole 211, and the side wall of the boss 24 has a first water outlet 241, such as Figure 5As shown, the second end 313 has a second outlet 3131 corresponding to the first outlet 241, and the first end 312 has a third outlet 3121; the first filter element 32 and the second filter element 33 are both located between the second outlet 3131 and the third outlet 3121; the mounting cavity is connected to the second liquid storage cavity 23 through the first outlet 241 and the second outlet 3131; the mounting cavity is connected to the first liquid storage cavity 121 through the third outlet 3121. The shape of the boss 24 can be various, for example, the boss 24 can be annular or square, as long as it is arranged around the through hole 211 to prevent water in the second liquid storage cavity 23 from flowing out of the through hole 211. Those skilled in the art can choose the setting according to actual needs. In practice, water in the second storage chamber 23 of the drinking tray 2 enters the mounting chamber through the first outlet 241 on the side wall of the boss 24 and the second outlet 3131 at the second end 313 of the mounting bracket 31. After being filtered by the first filter element 32 and the second filter element 33 located in the mounting chamber, water flows out from the third outlet 3121 at the first end 312 of the mounting chamber into the first storage chamber 121. The third outlet 3121 can be located on the side wall of the first end 312 of the mounting chamber or on the end face of the first end 312 of the mounting chamber, as long as it can allow the water filtered by the first filter element 32 and the second filter element 33 to flow into the first storage chamber 121. Multiple first outlets 241, second outlets 3131, and third outlets 3121 can be provided. Preferably, there is no gap between the outer wall of the second end 313 of the mounting bracket 31 and the inner wall of the boss 24, to prevent water in the second liquid storage chamber 23 from flowing directly into the first liquid storage chamber 121 without passing through the dual filtration of the first filter element 32 and the second filter element 33, thereby affecting the water quality. In one embodiment, the end face of the second end 313 of the mounting bracket 31 is provided with an opening (not shown) communicating with the mounting cavity, and a detachable cover 34 is provided at the opening. The second end 313 of the mounting bracket 31 is detachably disposed in the through hole 211 through the cover 34. The connection between the cover 34 and the opening of the mounting bracket 31 can be a threaded connection or a snap-fit ​​connection, as long as it can achieve the detachable connection of the cover 34 to the opening of the mounting bracket 31. Those skilled in the art can choose the setting according to actual needs. In order to facilitate the user to disassemble and install the cover 34, the disassembly direction and the installation direction can be marked on the cover 34.

[0041] Specifically, the first filter element 32 can be a filter screen, and the second filter element 33 can be a filter cartridge. The filter screen can be installed in the mounting bracket 31 through a filter screen holder. The filter screen can be provided with a first gripper for the user to grasp. The filter cartridge can be a cylindrical filter cartridge placed in the mounting cavity below the filter screen. The cylindrical filter cartridge can use activated carbon or nano-silver ceramic antibacterial particles as the filter medium, or other filter materials can be used as the filter medium. The cylindrical filter cartridge is provided with a second gripper for the user to grasp. When the filter cartridge or filter screen is clogged by pet hair or dirt, the user can remove the cover 34, and then use the first gripper to remove the filter screen from the mounting cavity for replacement or cleaning. Then, the user can use the second gripper to remove the cylindrical filter cartridge for replacement or cleaning. In one embodiment, the cylindrical filter element comprises an upper layer of sponge, a middle layer of sponge, and a lower layer of sponge. Filter media are provided between the upper and middle layers of sponge, and between the middle and lower layers of sponge. The media used between the upper and middle layers of sponge, and between the middle and lower layers of sponge, can be the same or different. Specifically, activated carbon can be provided between the upper and middle layers of sponge as the filter media, and nano-silver ceramic antibacterial particles can be provided between the middle and lower layers of sponge as the filter media.

[0042] In one embodiment, such as Figure 3 As shown, the wall of the through hole 211 extends towards the center of the through hole 211 to form a support ring 8, which is used to support the second end 313 of the mounting bracket 31. By providing the support ring 8, the mounting bracket 31 can be more securely installed at the through hole 211.

[0043] In one embodiment, the second end 313 of the mounting bracket 31 can be detachably mounted to the through hole 211 via the cover 34. Specifically, the edge of the cover 34 can extend away from the center of the cover 34 to form a blocking platform. The outer diameter of the blocking platform is larger than the inner diameter of the through hole 211, and naturally also larger than the inner diameter of the boss 24. The mounting bracket 31 is fixed by the blocking platform of the cover 34 abutting against the upper end face of the boss 24, that is, the cover 34 cannot fall into the through hole 211.

[0044] In one embodiment, the second end 313 of the mounting bracket 31 has a first overflow port 3133 communicating with the first liquid storage chamber 121. The lowest position of the first overflow port 3133 is higher than the lowest position of the second water outlet 3131. Specifically, when the first filter element 32 and the second filter element 33 in the mounting bracket 31 are blocked by pet hair or food residue, and the water flow cannot pass through the first filter element 32 and the second filter element 33, the water level in the second liquid storage chamber 23 will gradually rise. Due to the setting of the first overflow port 3133, when the water level in the second liquid storage chamber 23 rises to the lowest position of the first overflow port 3133, the water will flow directly into the first liquid storage chamber 121 through the first overflow port 3133, preventing water from overflowing from the drinking tray 2 onto the ground. Because the lowest point of the first overflow port 3133 is higher than the lowest point of the second outlet 3131, this prevents water from the second storage chamber 23 from flowing directly into the first storage chamber 121 from the first overflow port 3133 without being filtered by the filter assembly 3 when the filter assembly 3 is working normally. Preferably, a gap is provided between the first overflow port 3133 and the inner wall of the boss 24, which is more conducive to water in the second storage chamber 23 flowing into the first storage chamber 121 through the first overflow port 3133. In specific implementation, such as Figure 3 and Figure 5 As shown, a recess 3134 can be provided on the side of the second end 313 of the mounting bracket 31 facing the boss 24. A protrusion 242 corresponding to the recess 3134 is provided on the boss 24. The protrusion 242 of the boss 24 is accommodated in the recess 3134. The first overflow port 3133 is located on the mounting bracket 31 where the recess 3134 is provided, so that there is a gap between the first overflow port 3133 and the inner sidewall of the boss 24. By accommodating the protrusion 242 on the boss 24 in the recess 3134 of the mounting bracket 31, the mounting bracket 31 can be positioned so that the first outlet 241 and the second outlet 3131 match after the mounting bracket 31 is installed in the through hole 211.

[0045] In one embodiment, in conjunction with reference to Figure 1 and Figure 3The chassis 21 has a mounting hole 212. The water pump assembly 4 includes a water pump 41 and a nozzle 42 connected to each other. The water pump 41 is located inside the water storage tank 1. The end of the nozzle 42 away from the water pump 41 passes through the mounting hole 212 and protrudes from the chassis 21. The end of the nozzle 42 away from the water pump 41 has a spray nozzle 421. Multiple spray nozzles 421 can be provided on the nozzle 42. Each spray nozzle 421 can include multiple spray holes. Here, two spray nozzles 421 are used as an example. The two spray nozzles 421 of the nozzle 42 can spray water towards the two sides of the side wall of the boss 24. Since the water in the second liquid storage chamber 23 flows to the first outlet 241 of the boss 24, the two spray nozzles 421 spraying water towards the two sides of the side wall of the boss 24 can make it easier for the hair in the second liquid storage chamber 23 to be washed onto the filter screen, thus facilitating cleaning by the user. Specifically, one end of the nozzle 42 is connected to the water pump 41, and the other end of the nozzle 42 passes through the mounting hole 212 and protrudes from the chassis 21. The water pump 41 delivers water from the first storage chamber 121 into the end of the nozzle 42 connected to the water pump 41. The water in the nozzle 42 flows from the end closer to the water pump 41 to the end farther away from the water pump 41, and flows into the second storage chamber 23 through the spray nozzle 421 of the nozzle 42. In a specific implementation, the water pump 41 can be a wireless water pump, which can be installed in the water storage tank 1. The bottom of the wireless water pump is equipped with a receiving coil, and a main control module can be installed at the bottom of the water storage tank 1. The main control module can be electrically connected to the transmitting coil. The main control module controls the transmitting coil to transmit a current signal to the receiving coil, thereby driving the water pump 41 to transport the water in the first storage chamber 121 to the second storage chamber 23 through the nozzle 42. The use of wireless water pump magnetic induction power supply technology not only extends the service life of the water pump 41 but also separates water and electricity, preventing electrical conductivity and leakage, thereby improving the safety performance of the pet water fountain. In this embodiment, the assembly of the nozzle 42 with the wireless water pump makes it more convenient for user operation.

[0046] In one embodiment, in conjunction with reference to Figure 4 The nozzle 42 has a protrusion 422, and the wall of the mounting hole 212 has a groove 2121 that matches the protrusion 422. The protrusion 422 is located within the groove 2121. There can be one or more protrusions 422, and the shape of the protrusions 422 is not limited. In a specific implementation, the part of the nozzle 42 connected to the mounting hole 212 can be cylindrical, and there can be two protrusions 422 symmetrically arranged on the side wall of the cylindrical nozzle 42. By matching with the groove 2121 on the wall of the mounting hole 212, the nozzle 42 can be installed, positioned, and limited, ensuring that the nozzle 42 is correctly positioned within the mounting hole 212 and preventing the nozzle 42 from rotating within the mounting hole 212 and changing the water outlet direction of the nozzle 42.

[0047] In one embodiment, the chassis 21 has a raised ring 213 surrounding the outside of the boss 24, with the top of the raised ring 213 lower than the edge of the side plate 22. When the pet water fountain is powered off, water in the second storage chamber 23 that is higher than the raised ring 213 will flow sequentially from the first outlet 241, the second outlet 3131, and the third outlet 3121 into the first storage chamber 121. Water in the second storage chamber 23 that is lower than the raised ring 213 will be stored in the portion of the second storage chamber 23 located between the raised ring 213 and the side plate 22, ensuring that there is still water in the second storage chamber 23 for the pet to drink from, thus preventing the pet from having no water to drink due to a power outage. Specifically, the raised ring 213 can be integrally formed with the water tray 2, or the raised ring 213 can be a structure installed on the water tray 2. The mounting hole 212 is located between the convex ring 213 and the side plate 22, that is, the mounting hole 212 is on the outside of the convex ring 213. The water from the nozzle 42 first fills the part of the second liquid storage chamber 23 located between the convex ring 213 and the side plate 22 before entering the filter assembly 3 for filtration, which can also block large particles of foreign matter in the water. Then the water is filtered by the filter assembly 3.

[0048] In one embodiment, the side plate 22 is provided with a second overflow port 221 at the end away from the chassis 21, and the second overflow port 221 is connected to the first liquid storage chamber 121. Specifically, when the first filter element 32, the second filter element 33 and the first overflow port 3133 in the mounting bracket 31 are all blocked by pet hair or food residue, and the water cannot flow out and accumulates in the second liquid storage chamber 23, the water level in the second liquid storage chamber 23 will gradually rise and overflow outside the drinking tray 2. Due to the setting of the second overflow port 221, when the water level in the second liquid storage chamber 23 rises to the position of the second overflow port 221, the water will flow directly into the first liquid storage chamber 121 through the second overflow port 221, preventing water from overflowing from the drinking tray 2 onto the ground. Since the second overflow port 221 is located at the end of the side plate 22 of the drinking tray 2 away from the base 21, this prevents water from the second liquid storage chamber 23 from flowing directly into the first liquid storage chamber 121 through the second overflow port 221 without being filtered by the filter assembly 3 when the first filter 32, the second filter 33, and the first overflow port 3133 are working normally. The second overflow port 221 can be a through hole opened on the side plate 22, or a notch formed on the edge of the side plate 22, such as... Figure 3 As shown, the first liquid storage chamber 121 is located on the lower outer side of the side plate 22.

[0049] In one embodiment, the water storage tank 1 includes a detachably connected outer casing 11 and an inner casing 12, with a first liquid storage chamber 121 located within the inner casing 12. By adopting a detachable design, with the first liquid storage chamber 121 located within the inner casing 12, water is stored within the inner casing 12. When water needs to be added to the first liquid storage chamber 121, the inner casing 12 can be detached, filled with water, and then reinstalled onto the outer casing 11, thus facilitating user operation. Simultaneously, the main control module and related wiring can be located on the outer casing 11, thereby achieving water and electricity separation and avoiding electrical conductivity and leakage problems.

[0050] In one embodiment, the pet water dispenser further includes a main control module (not shown), a weighing module 5, a display module 6, and a WiFi module located in the outer casing 11. The weighing module 5, display module 6, and WiFi module (not shown) are all electrically connected to the main control module. The weighing module 5 weighs the inner casing 12 and feeds the weighing data back to the main control module. The main control module then controls the display module 6 to display the water level in the first storage chamber 121, allowing the user to easily observe the water level and add water to the first storage chamber 121 in a timely manner. Specifically, a cavity exists between the bottom of the outer casing 11 and the bottom of the inner casing 12. The main control module and the weighing module 5 are located within this cavity, and the display module 6 is located on the side wall of the outer casing 11.
