Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to a pet water dispenser. Background Technology

[0002] Traditional pet water fountains typically use a water pump combined with filter cotton to circulate and filter the water for pets. The pump draws water from the tank upwards to the drinking dish, which has a concave surface to hold the water for the pet. A float filter is located on the side wall of the drinking dish near the top; excess water passes through this filter, then through the filter cotton before flowing back into the tank, thus creating a filtration cycle. During this process, the filter cotton softens the water and filters out shed hair and food residue from the pet while drinking.

[0003] During the process of returning excess water to the water tank through the float filter, although floating impurities such as pet hair and dust can be carried to the filter cotton for filtration by the water flow, some sediment-forming impurities, such as food scraps and large dust particles, may be carried into the water dish during pet drinking. These sediment-forming impurities cannot be carried to the filter cotton for filtration, resulting in sediment remaining in the water dish. At the same time, since the float filter is located on the side wall near the top of the water dish, water below the float filter will remain in the water dish after the water pump stops working and cannot flow away. This water is exposed to the air and is easily contaminated, and it is also easy for pets to spill and wet the ground. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a pet water dispenser to solve the above problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pet water fountain, including a water tank, a water tray, a water pumping module and a filter box;

[0006] The drinking tray is provided with a water inlet, a return outlet that penetrates the surface of the drinking tray, and a floating debris filter that penetrates the side wall of the drinking tray;

[0007] The drinking tray is located on the upper side of the water tank. The water pumping module includes a water pump. The inlet of the water pump is connected to the water storage chamber of the water tank, and the outlet of the water pump is connected to the inlet of the drinking tray.

[0008] The filter box is disposed in the water storage chamber of the water tank, and the return port of the drinking tray extends into the filter box;

[0009] The filter box has a filter cotton inside, and the return port is connected to the water storage chamber of the water tank through the filter cotton.

[0010] Preferably, the inner cavity of the filter box is further provided with a partition, which divides the inner cavity of the filter box into a water collection chamber and a sedimentation water channel, wherein the sedimentation water channel is located between the partition and the side wall of the filter box, and the sedimentation water channel is connected to the filter outlet opened on the side wall of the filter box.

[0011] The inlet of the sedimentation water path is located on the bottom side of the side wall of the filter box, and the inlet of the sedimentation water path is connected to the water collection cavity;

[0012] The filter cotton is disposed in the water collection cavity to divide the water collection cavity into a pre-filtration cavity and a post-filtration cavity arranged vertically. The pre-filtration cavity is connected to the return port, and the post-filtration cavity is connected to the inlet of the sedimentation water path.

[0013] Specifically, the floating object filter port is connected to the pre-filter chamber.

[0014] It is worth noting that the water pumping module also includes a main housing and a water outlet assembly. The main housing, the water outlet assembly, and the water pump are arranged sequentially from top to bottom. The water outlet assembly includes a water outlet path and a water outlet pipe. The water outlet of the water pump is connected to the water outlet pipe through the water outlet path.

[0015] The water inlet of the drinking tray is equipped with a water inlet assembly, which includes a U-shaped water passage and a water inlet tube. The water inlet is connected to the water inlet tube through the U-shaped water passage.

[0016] The inlet tube is inserted into the outlet tube.

[0017] Preferably, the pumping module further includes a base, the base being connected to the water outlet assembly to form a mounting cavity between the base and the water outlet assembly, and the water pump being disposed within the mounting cavity;

[0018] The base is provided with a water suction groove, and the water inlet of the water pump is connected to the water storage chamber of the water tank through the water suction groove.

[0019] It is worth noting that both the reflux port and the floating matter filter port are located on the side of the drinking tray away from the water inlet, and the surface of the drinking tray gradually slopes downward from the water inlet toward the reflux port.

[0020] Specifically, the return port has an inverted horn structure.

[0021] Preferably, the base is provided with an exhaust hole, which communicates with the mounting cavity.

[0022] The beneficial effects of this invention are as follows: In the pet water fountain, a return outlet is added to the surface of the water-filled tray. Settled impurities can flow into the filter box through this outlet, while floating impurities can also flow with the water flow through the floating impurity filter outlet into the inner cavity of the filter box. The impurities are then filtered out by the filter cotton inside the filter box, and the filtered water flows back into the water tank's storage cavity. By starting the water pump, circulation is achieved. After the water pump is turned off, the water on the surface of the water tray will flow back through the filter box and into the storage cavity, ensuring that there is no water on the surface of the water tray after the pump stops. This prevents water from being exposed to the air and becoming contaminated, and also prevents pets from spilling water and wetting the floor. Attached Figure Description

Detailed Implementation

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1-8 As shown, a pet water fountain includes a water tank 1, a drinking tray 2, a water pumping module 3, and a filter box 4;

[0034] The drinking tray 2 is provided with a water inlet 22, a return outlet 21 penetrating the surface of the drinking tray 2, and a floating material filter outlet 23 penetrating the side wall of the drinking tray 2;

[0035] The drinking tray 2 is positioned above the water tank 1. The pumping module 3 includes a water pump 31, the inlet 311 of which is connected to the water storage chamber 11 of the water tank 1, and the outlet 312 of which is connected to the inlet 22 of the drinking tray 2. In this embodiment, as shown... Figure 7 As shown, the drinking tray 2 has an opening 25, and the water pumping module 3 extends into the water storage chamber 11 of the water tank 1 after passing through the opening 25, so that the water pump 31 is located in the water storage chamber 11 of the water tank 1; the water pumping module 3 and the water tank 1 are detachably connected, avoiding the situation in the existing solution where the water pumping module 3 arranged on the drinking tray 2 cannot be detached, which would make it inconvenient to clean.

[0036] The filter box 4 is disposed in the water storage chamber 11 of the water tank 1, and the return port 21 of the drinking tray 2 extends into the filter box 4;

[0037] The filter box 4 has a filter cotton 41 in its inner cavity, and the return port 21 is connected to the water storage cavity 11 of the water tank 1 through the filter cotton 41.

[0038] The floating object filter port 23 is connected to the filter box 4.

[0039] like Figure 3 As shown, the arrows indicate the direction of water flow. In the pet water fountain, a return port 21 is added to the surface of the water-filled tray 2. Settled impurities can flow into the filter box 4 through the return port 21. Simultaneously, impurities floating on the surface can also flow into the inner cavity of the filter box 4 through the floating impurity filter port 23. The impurities are then filtered out by the filter cotton 41 inside the filter box 4, and the filtered water flows back into the water storage chamber 11 of the water tank 1. Circulation is achieved by activating the water pump 31. After the water pump 31 is turned off, the water on the surface of the water tray 2 will flow back into the water storage chamber 11 through the return port 21 and the filter box 4, ensuring that there is no water on the surface of the water tray 2 after the water pump 31 stops. This prevents water from being exposed to air and becoming contaminated, and also prevents pets from spilling water and wetting the floor.

[0040] In practical use, the main sources of impurities are airborne dust or food scraps left over from pets' meals. These impurities are relatively small, making it unlikely that they would become large enough to completely block the return outlet 21. Furthermore, even if residue does completely block the return outlet 21, the user (pet owner) can easily see and clean it to resolve the issue, thus preventing blockage. Additionally, because the water is constantly flowing, hair will not instantly fall into the water in the water dish 2 and clog the return outlet 21. Moreover, the user (pet owner) can clean the water dish 2 and restore it to normal use based on actual usage, thereby preventing blockage of the return outlet 21.

[0041] It is worth noting that, such as Figure 3As shown, the inner cavity of the filter box 4 is further provided with a partition 42, which divides the inner cavity of the filter box 4 into a water collection chamber 43 and a sedimentation water channel 44. The sedimentation water channel 44 is located between the partition 42 and the side wall of the filter box 4, and the sedimentation water channel 44 is connected to the filter outlet 45 opened on the side wall of the filter box 4. The inlet of the sedimentation water channel 44 is located on the bottom side of the side wall of the filter box 4, and the inlet of the sedimentation water channel 44 is connected to the water collection chamber 43. The filter cotton 41 is disposed in the water collection chamber 43 to divide the water collection chamber 43 into a pre-filtration chamber 431 and a post-filtration chamber 432 arranged vertically. The pre-filtration chamber 431 is connected to the return port 21, and the post-filtration chamber 432 is connected to the inlet of the sedimentation water channel 44. In this embodiment, the water in the pre-filtration chamber 431 is the water before filtration by the filter cotton 41, and the water in the post-filtration chamber 432 is the water after filtration by the filter cotton 41. In existing filter boxes 4, the filter outlet 45 is typically located at the bottom of the filter cotton 41. This means that after water passes through the filter cotton 41, it flows directly back to the water tank 1. In this case, some smaller impurities that are not blocked by the filter cotton 41 will directly return to the water storage chamber 11 of the water tank 1, contaminating the water inside. To solve this problem, a baffle 42 is added, forming an L-shaped secondary sedimentation channel 44. Some smaller impurities that have passed through the filter cotton 41 will settle in the sedimentation channel 44 at the inlet because the filter outlet 45 of the filter box 4 is located at the top. These smaller impurities will then be settled in the sedimentation channel and not carried away. After the pet water fountain has been used for a period of time, the user can manually clean the impurities filtered out by the filter box 4 to ensure that the water in the water tank 1 remains clean during subsequent use.

[0042] Preferred, such as Figure 2 and 3 As shown, the drinking tray 2 is provided with a floating debris filter port 23 that penetrates the side wall of the drinking tray 2, and the floating debris filter port 23 is connected to the pre-filter chamber 431. Impurities such as hair floating on the water surface flow through the floating debris filter port 23 to the filter cotton 41 of the filter box 4 for filtration when the water exceeds the floating debris filter port 23.

[0043] Optional, such as Figure 4-6As shown, the water pumping module 3 also includes a main housing 32 and a water outlet assembly 33. The main housing 32, water outlet assembly 33, and water pump 31 are arranged sequentially from top to bottom. The water outlet assembly 33 includes a water outlet passage 331 and a water outlet pipe 332. The water outlet 312 of the water pump 31 is connected to the water outlet pipe 332 through the water outlet passage 331. The water inlet 22 of the drinking tray 2 is provided with a water inlet assembly 24. The water inlet assembly 24 includes a U-shaped water passage 242 and a water inlet pipe 241. The water inlet 22 is connected to the water inlet pipe 241 through the U-shaped water passage 242. The water inlet pipe 241 is inserted into the water outlet pipe 332. Figure 4 As shown, the arrows indicate the direction of water flow. After the water pump 31 starts, the water in the water storage chamber 11 of the water tank 1 enters through the inlet 311 of the water pump 31, then passes through the water pump 31, and then through the outlet assembly 33 into the U-shaped water passage 242 of the inlet assembly 24, finally entering the surface of the drinking tray 2 from the inlet 22. The inlet pipe 241 and the outlet pipe 332 are detachably connected, making it easy to remove the water pumping module 3 for cleaning the drinking tray 2 and the water tank 1.

[0044] Specifically, such as Figure 5 and 6 As shown, the pumping module 3 also includes a base 34, which is connected to the water outlet component 33 to form an installation cavity between the base 34 and the water outlet component 33. The water pump 31 is disposed in the installation cavity. The base 34 has a suction groove 341, and the water inlet 311 of the water pump 31 is connected to the water storage cavity 11 of the water tank 1 through the suction groove 341. Water in the water storage cavity 11 of the water tank 1 can enter the installation cavity through the suction groove 341, allowing the water pump 31 to be completely immersed in water. The base 34 also has a vent 342, which is connected to the installation cavity. As the water level rises, air in the installation cavity inside the base 34 can be discharged through the vent 342, preventing air pressure caused by poor venting from affecting the rise of the water level and thus affecting the normal operation of the water pump 31.

[0045] The water suction tank 341 is equipped with an inlet filter cotton 344, which covers the inlet 311. Water from the water storage chamber 11 of the water tank 1 enters the installation chamber from the water suction tank 341, passes through the inlet filter cotton 344, and then enters the water pump 31. This prevents impurities in the water tank 1 from being transferred to the drinking tray 2 by the water pump 31, and also prevents impurities from entering the water pump 31 and causing it to become clogged. The base 34 is also provided with a socket 343, and the water outlet tube 332 of the water outlet component 33 is disposed in the socket 343, so that the water inlet tube 241 of the water inlet component 24 of the drinking tray 2 can pass through the socket 343 and connect to the water outlet tube 332.

[0046] like Figure 8 As shown, the main unit housing 32 houses a main control board 321 and a battery 322, with the main control board 321 and battery 322 electrically connected by their power cords. The water pump power cord 323 of the water pump 31 passes through a cable hole at the bottom of the main unit housing 32 and is electrically connected to the main control board 321. Water ingress into the main unit housing 32 can be prevented by using a silicone plug 324 or waterproof adhesive between the water pump power cord 323 and the cable hole at the bottom of the main unit housing 32.

[0047] Preferred, such as Figure 7 As shown, both the return port 21 and the floating debris filter port 23 are located on the side of the drinking dish 2 away from the water inlet 22, and the surface of the drinking dish 2 gradually slopes downward from the water inlet 22 towards the return port 21. Thus, the return port 21 is located at the lowest point of the surface of the drinking dish 2, ensuring that impurities can flow towards the return port 21 and the floating debris filter port 23, thereby entering them. To ensure that the drinking dish 2 provides a certain amount of pure water for the pet to drink each time, the aperture of the return port 21 should be smaller than the aperture of the water inlet 22 of the drinking dish 2.

[0048] Preferably, the return port 21 has an inverted horn structure. The inverted horn structure of the return port 21 can create a vortex suction force, which discharges the sedimented impurities through the return port 21 onto the filter box 4, thereby filtering the bottom residue.

[0049] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
