[0011] Preferably, the water outlet platform and the water holding platform are smoothly connected, and the connecting section between the water outlet platform and the water holding platform is a slope, the height of which gradually decreases from the side closer to the water outlet platform to the side closer to the water holding platform.

[0012] Preferably, the upper surface of the slope is recessed on both sides to form a second sub-concave surface, and each second sub-concave surface extends along the extension direction of the slope. The first concave surface includes two first sub-concave surfaces that are continuously undulating and symmetrically arranged on both sides of the water nozzle. The two second sub-concave surfaces are smoothly connected to the two first sub-concave surfaces in a one-to-one correspondence.

[0013] In addition, the present invention also proposes a pet water fountain, which includes a drinking tray as described above, a water tank, and a water supply mechanism. The drinking tray is disposed on the water tank, and the water supply mechanism includes a pumping drive and a water pipe disposed within the water tank. The water pipe connects the spray nozzle and the pumping drive, and the pumping drive is used to pump drinking water from the water tank to the spray nozzle.

[0014] Preferably, the water outlet platform is provided with a connector that communicates with the water nozzle, and the inner diameter of the connector is gradually widened from the water nozzle toward the direction away from the water nozzle, and the end of the water pipe away from the water pumping drive is sleeved on the outer periphery of the connector.

[0015] Preferably, the drinking tray is detachably connected to the water tank, and the drinking tray is also provided with a handle.

[0016] Preferably, the pet water fountain further includes a filter assembly located inside the water tank, the filter assembly being connected to the side of the drinking tray near the water tank, and the filter assembly being configured corresponding to the first water outlet.

[0017] Preferably, the filtration assembly includes a filter housing and a filter element. The filter housing is detachably connected to the drinking tray. A filtration channel is formed inside the filter housing. A second water inlet and a second water outlet, both of which are connected to the filtration channel, are opened on the filter housing. The second water inlet is connected to the first water outlet, and the second water outlet is connected to the water tank. The filter element is disposed in the filtration channel and located between the second water inlet and the second water outlet.

[0018] Preferably, a portion of the sidewall of the filter housing is disposed close to the wall of the water tank, the wall of the water tank is provided with a water flow step, a portion of the bottom wall of the filter housing is placed on the water flow step, a second water outlet is provided on the portion of the sidewall of the filter housing close to the wall of the water tank, corresponding to the water flow step, and a plurality of support plates are provided at intervals on the bottom wall of the filter housing, extending into the filter channel and used to support the filter element.

The outlet platform is higher than the holding platform. The outlet platform has a spray nozzle. The surface of the outlet platform surrounding the spray nozzle is concave downwards to form a first concave surface. The first concave surface is used to spread the water sprayed from the spray nozzle and guide it to the holding platform. The holding platform has a first outlet. When the pet water fountain is working, the spray nozzle sprays water for the pet to drink. Because the surface of the outlet platform surrounding the spray nozzle is concave downwards to form the first concave surface, the drinking water sprays from the spray nozzle to the first concave surface. The first concave surface can spread the water flow and guide it to the holding platform. Furthermore, because the height of the outlet platform is higher than the height of the holding platform, the spread drinking water is washed from the outlet platform to the holding platform, avoiding the formation of water vortexes that would cause hair to swirl inside the water bowl. This invention uses water jets from the spray nozzles to flush animal hair and food scraps in the drinking area to the first water outlet, thus protecting pets from swallowing their hair and food scraps while drinking.

[0039] This invention proposes a water bowl and a pet water fountain, aiming to solve the problem that pets easily swallow pet hair and food residue while drinking water, which affects their health.

[0040] Please refer to Figure 1 , Figure 4 and Figure 5 The water bowl 21 is used for pet water fountains. The water bowl 21 includes a water outlet platform 211 and a water holding platform 212 connected to each other. The water outlet platform 211 is higher than the water holding platform 212. The water outlet platform 211 is provided with a water nozzle 2111. The surface of the water outlet platform 211 surrounding the water nozzle 2111 is recessed downward to form a first concave surface 2112. The first concave surface 2112 is used to spread the water sprayed from the water nozzle 2111 and guide it to the water holding platform 212. The water holding platform 212 is provided with a first water outlet 2121.

[0041] The water dispenser 21 of the present invention is used in a pet water fountain. The water dispenser 21 includes a water outlet platform 211 and a water holding platform 212 connected to each other. The water outlet platform 211 is higher than the water holding platform 212. The water outlet platform 211 is provided with a water nozzle 2111. The surface of the water outlet platform 211 surrounding the water nozzle 2111 is recessed downward to form a first concave surface 2112. The first concave surface 2112 is used to spread the water sprayed from the water nozzle 2111 and guide it to the water holding platform 212. The water holding platform 212 is provided with a first water outlet 2121. When the pet water fountain is working, the nozzle 2111 sprays water for the pet to drink. Because the surface of the water outlet 211 around the nozzle 2111 is concave downward to form a first concave surface 2112, it can form a shape similar to a volcano. The drinking water sprays from the nozzle 2111 to the first concave surface 2112, which can spread the water flow and guide it to the water collection platform 212. Furthermore, since the height of the water outlet 211 is higher than the height of the water collection platform 212, the spread drinking water can be washed from the water outlet 211 to the water collection platform 212 over a large area, forming a waterfall flow. This can increase the activity and oxygen content of the drinking water, and also provide impact force, which can effectively wash away pet hair and food residue in the drinking area 12. In addition, the large area of ​​flowing water can attract pets, increasing the frequency and amount of water they drink. The present invention can use the water flow sprayed from the water nozzle 2111 to flush the animal hair and food residue in the drinking area 12 to the first water outlet 2121 for discharge, thereby protecting the pet from swallowing pet hair and food residue while drinking.

[0042] In this regard, please combine Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the height of the water outlet platform 211 gradually decreases from the side of the water outlet platform 211 away from the water holding platform 212 towards the side of the water holding platform 212. To facilitate the smooth flow of drinking water in the first concave surface 2112 to the water holding platform 212, the water outlet platform 211 is tilted, and the first concave surface 2112 of the water outlet platform 211 is also tilted accordingly. Specifically, the height of the water outlet platform 211 gradually decreases from the side of the water outlet platform 211 away from the water holding platform 212 towards the side of the water holding platform 212.

[0043] The height of the water outlet face of the nozzle 2111 gradually decreases from the side away from the water-collecting platform 212 towards the side closer to the water-collecting platform 212. In order to ensure that the water sprayed from the nozzle 2111 can spread out smoothly and flow smoothly to the water-collecting platform 212, the height of the water outlet face of the nozzle 2111 can be set to gradually decrease from the side away from the water-collecting platform 212 towards the side closer to the water-collecting platform 212.

[0044] Furthermore, the water container 212 has a downwardly recessed second concave surface 2122, and the first water outlet 2121 is located on the side of the second concave surface 2122 away from the water outlet 211. In order to make it convenient for pets to drink the drinking water from the water container 212, the water container 212 has a downwardly recessed second concave surface 2122. The drinking water on the water outlet 211 flows into the second concave surface 2122 of the water container 212, and the pet can put its mouth into the second concave surface 2122 to drink the drinking water. Moreover, the first water outlet 2121 is located on the side of the second concave surface 2122 away from the water outlet 211. When the pet gets drinking water, the water flow can wash pet hair and food residue into the first water outlet 2121 and discharge it from the water container 212 through the first water outlet 2121.

[0045] Furthermore, in one embodiment, all corners of the first concave surface 2112 are rounded corners. To reduce obstruction to the flow of drinking water and increase its flow potential energy for better flushing of the water-holding platform 212, all corners of the first concave surface 2112 are rounded corners. In another embodiment, all corners of the second concave surface 2122 are rounded corners to facilitate the flow of drinking water and to carry pet hair and food scraps to the first outlet 2121.

[0046] Furthermore, the first water outlet 2121 is arranged around the outer periphery of the second concave surface 2122. In order to allow pet hair and food scraps to be discharged from the first water outlet 2121 more quickly, the first water outlet 2121 can be arranged around the outer periphery of the second concave surface 2122. The water flow washes the pet hair and food scraps to the outer periphery of the second concave surface 2122 and discharges them quickly through the first water outlet 2121, which can effectively prevent pet hair and food scraps from flowing back into the second concave surface 2122.

[0047] In another embodiment, the water outlet platform 211 and the water collection platform 212 are smoothly connected, and the connecting section between the water outlet platform 211 and the water collection platform 212 is a ramp 213. The height of the ramp 213 gradually decreases from the side closer to the water outlet platform 211 towards the side closer to the water collection platform 212. To prevent drinking water from splashing off the drinking tray 21 when it flows from the water outlet platform 211 to the water collection platform 212, the drinking tray 21 also includes a ramp 213 connecting the water outlet platform 211 and the water collection platform 212. The height of the ramp 213 gradually decreases from the side closer to the water outlet platform 211 towards the side closer to the water collection platform 212. The drinking water from the water outlet platform 211 flows along the ramp 213 to the water collection platform 212, and the ramp 213 guides the flow of drinking water.

[0048] The upper surface of the slope 213 is recessed on both sides to form a second sub-concave surface 2131. Each second sub-concave surface 2131 extends along the extension direction of the slope 213. The first concave surface 2112 includes two first sub-concave surfaces that are continuously undulating and symmetrically arranged on both sides of the water nozzle 2111. The two second sub-concave surfaces 2131 are smoothly connected to the two first sub-concave surfaces one by one. To increase the impact force of drinking water from the water outlet 211 into the water collection platform 212, so as to flush pet hair, cat litter, and food scraps from the water collection platform 212 to the first water outlet 2121, the upper surface of the slope 213 is recessed on both sides to form a second sub-concave surface 2131. Each second sub-concave surface 2131 is set along the inclined direction of the slope 213. The first concave surface 2112 includes two first sub-concave surfaces that are continuously undulating and symmetrically arranged on both sides of the water outlet 2111. The two second sub-concave surfaces 2131 are smoothly connected to the two first sub-concave surfaces one by one. The drinking water in each first sub-concave surface flows into the corresponding second sub-concave surface 2131.

[0049] In addition, the present invention also proposes a pet water fountain, which includes a drinking tray 21 as described above, a water tank 1, and a water supply mechanism 3. The drinking tray 21 is disposed on the water tank 1. The water supply mechanism 3 includes a water pumping drive 31 and a water pipe 32 disposed in the water tank 1. The water pipe 32 connects the spray nozzle 2111 and the water pumping drive 31. The water pumping drive 31 is used to pump drinking water from the water tank 1 to the spray nozzle 2111. The specific structure of the drinking tray 21 in this pet water fountain is as described in the above embodiments. Since this pet water fountain adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] The water tank 1 is provided with a spray area 11 and a drinking area 12. The drinking mechanism 2 includes a drinking tray 21 on the water tank 1. The drinking tray 21 includes a water outlet platform 211 and a water holding platform 212 connected to each other. The height of the water outlet platform 211 is higher than the height of the water holding platform 212. The water outlet platform 211 is located in the spray area 11 and is provided with a spray nozzle 2111. The water holding platform 212 is located in the drinking area 12 and is provided with a first water outlet 2121. The surface of the water outlet platform 211 surrounding the spray nozzle 2111 is recessed downward to form a first concave surface 2112. The water supply mechanism 3 includes a water pumping drive 31 and a water pipe 32 provided in the water tank 1. The water pipe 32 connects the spray nozzle 2111 and the water pumping drive 31. When the pet water fountain is working, the water pumping drive 31 pumps the drinking water in the water tank 1 to the spray nozzle 2111 through the water pipe 32.

[0051] In the above embodiment, the water outlet platform 211 is provided with a connector 2114 communicating with the water nozzle 2111. The inner diameter of the connector 2114 gradually expands from the water nozzle 2111 in the direction away from the water nozzle 2111. The end of the water pipe 32 away from the water pumping drive 31 is sleeved on the outer periphery of the connector 2114. Because the inner diameter of the connector 2114 gradually expands from the water nozzle 2111 in the direction away from the water nozzle 2111, the drinking water can form a dispersion effect when it is sprayed from the water nozzle 2111, thereby facilitating its fall into the first concave surface 2112.

[0052] Furthermore, to achieve multiple functions, the outer periphery of the connector 2114 is provided with an axial abutment step and multiple radial abutment steps. The multiple radial abutment steps are spaced apart along the axial direction of the connector 2114 and all abut against the inner wall of the water pipe 32. The axial abutment step is located between the radial abutment step and the nozzle 2111 and abuts against the end of the water pipe 32. To make the connection between the water pipe 32 and the connector 2114 more reliable, the outer periphery of the connector 2114 is provided with an axial abutment step and multiple radial abutment steps. The multiple radial abutment steps are spaced apart along the axial direction of the connector 2114 and all abut against the inner wall of the water pipe 32, thereby allowing the water pipe 32 to be securely fitted onto the outer periphery of the connector 2114. Moreover, the axial abutment step is located between the radial abutment step and the nozzle 2111 and abuts against the end of the water pipe 32, which facilitates the positioning of the water pipe 32 during assembly with the connector 2114.

[0053] In one embodiment, please refer to Figure 5As shown, the drinking tray 21 is detachably connected to the water tank 1, and the drinking tray 21 is also equipped with a handle 2115. In order to facilitate the removal of the drinking tray 21, a handle 2115 can be set on the water outlet 211. The position of the handle 2115 can be set according to the actual situation, so that the handle 2115 is located on the side of the water outlet 211 away from the water holding platform 212, which is both convenient and hygienic.

[0054] Furthermore, please combine Figure 5 , Figure 7 and Figure 8 As shown, the pet water fountain also includes a base 4 and a weighing mechanism 5. The water tank 1 is mounted on the base 4. The base 4 has an installation cavity 41. Multiple through holes 42 are spaced apart at the bottom of the base 4. All through holes 42 are connected to the installation cavity 41. The weighing mechanism 5 is located in the installation cavity 41. The weighing mechanism 5 includes a control board 51 and multiple weighing sensors 52 that are electrically connected to the control board 51. The number of weighing sensors 52 is the same as the number of through holes 42 and they are set one-to-one. Each weighing sensor 52 is exposed at the bottom of the base 4. To make the pet water fountain more aesthetically pleasing, a base 4 can be installed outside the water tank 1. The base 4 has a receiving groove to accommodate part of the structure of the water tank 1. During assembly, the water tank 1 can simply be placed in the receiving groove. In addition, to monitor the pet's daily water consumption, the pet water fountain also includes a weighing mechanism 5 located in the mounting cavity 41. The base 4 has a mounting cavity 41, and multiple through holes 42, which are all connected to the mounting cavity 41, are evenly spaced at the bottom of the base 4. The weighing mechanism 5 includes a control board 51 and multiple weighing sensors 52, which are all electrically connected to the control board 51. The number of weighing sensors 52 is the same as the number of through holes 42 and they are set one-to-one. The number of weighing sensors 52 can be set according to needs, such as 3 or 4. Each weighing sensor 52 is exposed at the bottom of the base 4 and the weighing sensors 52 are evenly distributed at the bottom of the pet water fountain.

[0055] Furthermore, the water supply mechanism 3 also includes a wireless charging module 33 disposed in the installation cavity 41. The wireless charging module 33 is electrically connected to the control board 51, and the wireless charging module 33 is correspondingly disposed with the water pumping drive component 31. The water pumping drive component 31 has a wireless power receiving module that is electromagnetically induced by the wireless charging module 33. To make the power supply of the pumping drive unit 31 safer, the power supply of the pumping drive unit 31 can be set to wireless power supply. That is, the water supply mechanism 3 also includes a wireless charging module 33 located in the mounting cavity 41. The wireless charging module 33 is electrically connected to the control board 51, and the wireless charging module 33 is correspondingly set to the pumping drive unit 31. The pumping drive unit 31 has a wireless power receiving module that is electromagnetically induced by the wireless charging module 33. When it is necessary to supply power to the pumping drive unit 31, simply insert the plug connected to the control board 51 into the power socket. The current flows through the control board 51 and to the wireless charging module 33. The wireless charging module 33 generates electromagnetic induction, and from electricity to magnetism, the wireless power receiving module generates electromagnetic induction under this magnetic field, and from magnetism to electricity, thereby supplying power to the pumping drive unit 31.

[0056] Additionally, please combine Figure 4 and Figure 5 As shown in the above embodiment, the drinking mechanism 2 further includes a filter assembly 22 located inside the water tank 1. The filter assembly 22 is connected to the side of the drinking tray 21 near the water tank 1, and the filter assembly 22 is correspondingly arranged with the first water outlet 2121. In order to allow the water discharged from the first water outlet 2121 to be reused so that the pet can drink continuously, the drinking mechanism 2 further includes a filter assembly 22 located inside the water tank 1. The filter assembly 22 is connected to the side of the drinking tray 21 near the water tank 1, and the filter assembly 22 is correspondingly arranged with the first water outlet 2121. Thus, the water flowing out of the first water outlet 2121 is first filtered by the filter assembly 22 into drinking water for the pet, and then enters the water tank 1. The water is then pumped to the spray nozzle 2111 by the water pumping drive 31 inside the water tank 1, and enters the water basin 212 for the pet to drink again.

[0057] Furthermore, the filter assembly 22 includes a filter housing 221 and a filter element 222. The filter housing 221 is detachably connected to the drinking tray 21. A filter channel 2211 is formed inside the filter housing 221. A second water inlet 2212 and a second water outlet 2213, both communicating with the filter channel 2211, are provided on the filter housing 221. The second water inlet 2212 communicates with the first water outlet 2121, and the second water outlet 2213 communicates with the water tank 1. The filter element 222 is disposed within the filter channel 2211 and located between the second water inlet 2212 and the second water outlet 2213. In this embodiment, the filter assembly 22 includes a filter housing 221 and a filter element 222. The filter housing 221 is detachably connected to the drinking tray 21, so that the filter assembly 22 can be separated from the drinking tray 21 when cleaning the pet water fountain, making cleaning more convenient and thorough. Furthermore, a filter channel 2211 is formed inside the filter housing 221. A second inlet 2212 and a second outlet 2213 are provided on the filter housing 221, both of which are connected to the filter channel 2211. The second inlet 2212 is connected to the first outlet 2121, and the second outlet 2213 is connected to the water tank 1. The water flowing out of the first outlet 2121 enters the filter channel 2211 through the second inlet 2212 and is filtered by the filter element 222 located in the filter channel 2211 and between the second inlet 2212 and the second outlet 2213. The water then enters the water tank 1 through the second outlet 2213.

[0058] Furthermore, the filter housing 221 includes a first housing and a second housing that are detachably connected to each other. The first housing is detachably connected to the drinking tray 21. The second housing is located on the side of the first housing away from the drinking tray 21 and forms a filter channel 2211 with the first housing. The first housing has a second water inlet 2212 and the second housing has a second water outlet 2213. To facilitate cleaning and eliminate blind spots, the filter housing 221 can be configured as a first housing and a second housing that are detachably connected. By detachably connecting the first housing to the drinking tray 21, during installation, the first housing is connected to the drinking tray 21, and the filter element 222 is placed inside the second housing. The second housing is then connected to the side of the first housing facing away from the drinking tray 21, thus placing the filter element 222 within the filter channel 2211 formed by the first and second housings. Furthermore, the first housing has a second inlet 2212, and the second housing has a second outlet 2213, allowing the filter element 222 to be positioned between the second inlet 2212 and the second outlet 2213. The second inlet 2212 can be located on the top wall or side wall of the first housing, and the second outlet 2213 can be located on the side wall or bottom wall of the second housing. Since the first housing can prevent pet hair and other objects from entering the filter channel 2211, it can prevent pet hair and other objects from directly covering the filter element 222, thereby reducing the impact on the filtration effect and water flow rate of the filter element 222.

[0059] In one embodiment, there are multiple second water inlets 2212, which are evenly spaced on the first housing. To increase the water flow rate, multiple second water inlets 2212 are used, and they are evenly spaced on the first housing. Furthermore, the water flow rate can also be increased by increasing the size of the second water inlets 2212.

In one embodiment, the filter element 222 includes a support, a filter layer, and two isolation layers, which are respectively disposed on both sides of the filter layer. The support has a fixing hole for accommodating the filter layer and the two isolation layers. The wall of the fixing hole has a fixing step. When assembling the filter element 222, one isolation layer can be fixed to one side of the fixing step, the filter layer can be placed on the isolation layer, and the other isolation layer can be fixed to the other side of the fixing step, thereby fixing the filter layer between the two isolation layers. The isolation layer can be made of PP mesh or PET cotton, or other materials that can isolate and allow water to pass through. The isolation layer also has a certain filtering function, which can filter out fine hair and impurities in the water. The filter layer can be made of activated carbon, ion exchange resin, maifan stone, and KDF water gold, etc. Activated carbon can remove residual chlorine and other odors in the water, ion exchange resin can remove calcium and magnesium ions to soften the water, maifan stone can filter impurities in the water, and KDF water gold can reduce heavy metal residues and microbial growth in the water.

[0064] Furthermore, there are multiple filter layers, which are stacked on top of each other, and an isolation layer is provided between any two adjacent filter layers. An isolation layer is provided at the top of the top filter layer and at the bottom of the bottom filter layer. The number of fixed steps is the same as the number of isolation layers and they correspond to each other. To ensure thorough filtration of the water at the first outlet 2121, multiple filter layers can be stacked, with an isolation layer between any two adjacent filter layers. An isolation layer is also provided at the top of the top filter layer and the bottom of the bottom filter layer. The number of fixed steps corresponds to the number of isolation layers and they abut against each other. In one embodiment, there are five fixed steps: a first step, a second step, a third step, a fourth step, and a fifth step. There are three filter layers: a first filter material layer, a second filter material layer, and a third filter material layer. The first and second steps form a volume cavity through the isolation layer, which is filled with the first filter material to form a first filter material layer. The second and third steps form a volume cavity through the isolation layer, which is filled with the second filter material to form a second filter material layer. The fourth and fifth steps form a volume cavity through the isolation layer, which is filled with the third filter material to form a third filter material layer. With these three filter layers stacked, wastewater passes through sequentially, effectively purifying the water.

A second water outlet 2213, corresponding to the water flow step 13, is provided on the sidewall of the filter housing 221 close to the wall of the water tank 1. Water flowing out from the second water outlet 2213 passes through the water flow step 13 and can be introduced into the water tank 1 by the water flow step 13, thereby eliminating the sound of falling water. Since there is a height difference between the second water outlet 2213 and the water level in the water tank 1, the water flow step 13 is located between the second water outlet 2213 and the water level, which can eliminate the sound of falling water. Moreover, a plurality of support plates 2214 extending into the filter channel 2211 are provided at intervals on the bottom wall of the filter housing 221. The filter element 222 is placed on the support plate 2214, so that the water filtered by the filter element 222 can flow through the channel between the support plates 2214 to the second water outlet 2213.

[0066] Furthermore, a second outlet 2213 is also provided on the bottom wall of the portion of the filter shell 221 that is placed on the water flow step 13. The bottom of this portion of the bottom wall of the filter shell 221 that is placed on the water flow step 13 has multiple spaced protrusions 2215 that abut against the water flow step 13. To accelerate the water flow, a second outlet 2213 can also be provided on the bottom wall of the portion of the filter shell 221 that is placed on the water flow step 13. The bottom of this portion of the bottom wall of the filter shell 221 that is placed on the water flow step 13 has multiple protrusions 2215 that abut against the water flow step 13. These multiple protrusions 2215 are spaced apart, creating a gap between the bottom of the filter shell 221 and the water flow step 13. Water flows out from the second outlet 2213 at the bottom and flows into the water tank 1 through the gap along the wall of the water tank 1.

[0067] In one embodiment, the water tank 1 is a transparent water tank 1. The transparent water tank 1 can be made of transparent materials such as PC or acrylic, making it easy to observe the drinking water inside the water tank 1.
