[0001] This invention belongs to the field of pet water dispenser technology, specifically relating to a pet water dispenser that separates water and electricity. Background Technology

[0002] Pet water fountains are automated devices used to provide drinking water for pets. They typically consist of a water tank, a water pump, and a drinking tray. The pump draws water from the tank to the tray for the pet to drink. However, in most pet water fountains on the market today, the water pump and other electrical components are usually located inside the water tank. Since the pump is constantly submerged in water, its sealing structure can age, allowing water to seep into the motor. When the motor is powered on, this can create a path between the pump and the water flow in the tray, potentially posing a risk of electric shock to the pet. Summary of the Invention

Unless otherwise stated, "a plurality of" means two or more.

[0023] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] Please see Figures 1 to 17 This application provides a water and electricity separation pet water dispenser 100, including a base 10, a water tray 20, a clean water tank 30, and a water supply mechanism 40.

[0025] The base 10 includes a support 11 and a mounting part 12 disposed on the support 11; the drinking tray 20 is disposed on the support 11 and located below the mounting part 12; the clean water tank 30 is disposed on the support 11 and located below the drinking tray 20; the water supply mechanism 40 includes a pump body 41 and an inlet pipe 42 connected to the inlet of the pump body 41 and an outlet pipe 43 connected to the outlet of the pump body 41. The pump body 41 is mounted on the mounting part 12, the inlet pipe 42 extends into the clean water tank 30, and the end of the outlet pipe 43 is located above the drinking tray 20.

[0026] The aforementioned pet water fountain 100 with water and electricity separation, by installing the pump body 41 on the mounting part 12 located above the water tray 20, and the water outlet pipe 43 also located above the water tray 20, effectively isolates the live part of the pump body 41 from the water, thus achieving water and electricity separation. This avoids the pump body 41 from being immersed in water for a long time, which may cause safety hazards such as leakage, and ensures the pet's drinking water safety.

[0027] In this embodiment, both the drinking tray 20 and the purified water tank 30 are detachably mounted on the support 11, thereby facilitating disassembly and cleaning of the drinking tray 20 and the purified water tank 30. Further details can be found in the following description. Figure 1 and Figure 2 The support portion 11 of the base 10 includes a chassis 111 and a vertical section 112, with the chassis 111 and the mounting portion 12 located at opposite ends of the vertical section 112. The mounting portion 12 is rotatably mounted on the support portion 11, for example, via a pivot, hinge, or other rotatable connection to the top of the support portion 11. Thus, when the drinking tray 20 needs to be disassembled for cleaning, the mounting portion 12 is flipped upwards relative to the support portion 11 to expose the drinking tray 20, facilitating its disassembly and installation. Simultaneously, after disassembling the drinking tray 20, the purified water tank 30 can be further disassembled. Alternatively, in another embodiment, the drinking tray 20 and the purified water tank 30 can be pulled out horizontally without rotating the mounting portion 12.

[0028] For ease of description, this application defines: Figure 1 The view shown is the baseline. Figure 1 The left side of the observer is "left", the right side is "right", the top is "up", the bottom is "down", the direction perpendicular to the plane of the drawing outward is "front", and the direction perpendicular to the plane of the drawing inward is "back". The "length direction" mentioned in this application refers to the left-right direction along the pet water fountain 100, and the "width direction" refers to the front-back direction along the pet water fountain 100.

[0029] Specifically, in this embodiment, when the mounting part 12 is rotated, the support part 11 is provided with a first rotating shaft, the mounting part 12 is provided with a rotating ear, and the rotating ear is rotatably disposed on the first rotating shaft, so that the mounting part 12 can be rotated and flipped open relative to the vertical.

[0030] Further, please refer to Figures 3 to 6When the mounting part 12 is rotated to avoid detaching the drinking tray 20, in order to allow the water inlet pipe 42 to draw water to the bottom of the water tank 30 as much as possible, the water inlet pipe 42 in this embodiment includes a detachably connected first pipe part 421 and a second pipe part 422. The first pipe part 421 is connected to the water inlet of the pump body 41 and fixed to the mounting part 12, and the second pipe part 422 is fixed inside the water tank 30. In this way, by setting the water inlet pipe 42 to be detachably connected first pipe part 421 and second pipe part 422, when the mounting part 12 is flipped open relative to the support part 11, the first pipe part 421 and the second pipe part 422 can be separated from each other, so that the mounting part 12 can be freely flipped without being restricted by the pull of the water inlet pipe 42.

[0031] Specifically, the first pipe section 421 can be a rigid pipe, with one end connected to the water inlet of the pump body 41 and the other end extending downward to a position near the drinking tray 20. Since the first pipe section 421 is fixed to the mounting part 12, when the mounting part 12 is flipped, the first pipe section 421 also rotates synchronously. The second pipe section 422 is fixed inside the water purification tank 30, with one end extending into the bottom or near the bottom of the water purification tank 30 so as to draw water from the water purification tank 30, and the other end extending upward to the top opening of the water purification tank 30 or extending to the outside of the water purification tank 30 for docking with the first pipe section 421. When the mounting part 12 is reset, the first pipe section 421 and the second pipe section 422 can be reconnected and connected to form a complete water inlet passage.

[0032] In one embodiment, the detachable connection between the first pipe section 421 and the second pipe section 422 can be achieved using quick-connect couplings or plug-in couplings, facilitating user operation. Alternatively, in another embodiment, the water inlet pipe 42 can be configured as a retractable threaded pipe, allowing the water inlet pipe to extend or retract when the mounting section 12 rotates relative to the support, thereby opening the mounting section 12. This eliminates the need for the water inlet pipe 42 to be configured as two separate parts, thus reducing the structural complexity of their connection.

[0033] Specifically, please refer to Figure 6In achieving a detachable connection between the first pipe section 421 and the second pipe section 422, to enable a quick and sealed detachable connection and mutual communication between the first pipe section 421 and the second pipe section 422, the water inlet pipe 42 in this embodiment further includes a ball head 423. The ball head 423 can be connected to the end of the first pipe section 421 facing the second pipe section 422, or to the end of the second pipe section 422 facing the first pipe section 421. Specifically, in this embodiment, the ball head 423 is connected to the lower end of the first pipe section 421. Taking the end as an example, the ball head 423 is roughly spherical in shape, with a through water flow channel 4231 inside. The outer surface of the ball head 423 is a smooth spherical surface. The ball head 423 and the first pipe section 421 can be connected by means of integral molding, bonding, or threaded connection. When the mounting part 12 is adjusted from the flipped state to the closed state, in one embodiment, the second pipe section 422 can be inserted into the water flow channel 4231 of the ball head 423, thereby realizing the conduction between the first pipe section 421 and the second pipe section 422. In this way, the ball head 423 enables quick and accurate docking between the first pipe section 421 and the second pipe section 422, while ensuring the sealing of both.

[0034] Furthermore, in addition to the ball head 423 in the inlet pipe 42, the inlet pipe 42 also includes a connector 424. The connector 424 has a groove 4241 for accommodating at least a portion of the ball head 423. Specifically, one of the first pipe section 421 and the second pipe section 422 has the ball head 423, and the other has the connector 424. Specifically, the first pipe section 421 has the ball head 423, and the second pipe section 422 has the connector 424. That is, the connector 424 is located at the upper end of the second pipe section 422, and the groove 4241 is recessed downward from the upper end surface of the connector 424. The inner wall shape of the groove 4241 matches the outer surface shape of the ball head 423, and is approximately a spherical shape that fits the ball head 423. Thus, when the ball head 423 is inserted into the groove 4241, the outer surface of the ball head 423 and the inner wall of the groove 4241 fit tightly together, forming a sealed fit with sufficient sealing to prevent water leakage. At the same time, the ball head 423 and the groove wall of the groove 4241 are rotatably fitted, so that the first tube 421 and the second tube 422 can still rotate relative to each other at a certain angle when connected, thereby facilitating the flipping action of the mounting part 12.

[0035] In another embodiment, an annular sealing groove can be provided on the outer surface of the ball head 423, and a sealing ring is installed in the sealing groove to further improve the sealing performance between the ball head 423 and the groove 4241. When the ball head 423 is inserted into the groove 4241, the sealing ring is compressed between the ball head 423 and the inner wall of the groove 4241, forming a multiple sealing effect; or an annular sealing groove can be provided on the groove wall of the groove 4241, and a sealing ring is installed in the sealing groove. When the ball head 423 is inserted into the groove 4241, the sealing ring is compressed between the ball head 423 and the inner wall of the groove 4241, which can also achieve a multiple sealing effect.

[0036] Specifically, when the second pipe section 422 is installed inside the water purification tank 30, a first retaining groove 31 is provided on the inner wall of the water purification tank 30, and the second pipe section 422 is installed in the first retaining groove 31 to fix the second pipe section 422. It should be noted that the bottom end of the second pipe section 422 needs to have a certain gap with the inner side of the bottom wall of the water purification tank 30 to ensure that the pump body 41 can draw water from the water purification tank 30.

[0037] Further, please refer to Figure 7 Since the water inlet pipe 42 needs to pass through the drinking tray 20 to extend into the clean water tank 30 located below the drinking tray 20, the end of the drinking tray 20 connected to the base 10 is provided with a relief opening 22. The water inlet pipe 42 passes through the relief opening 22. Specifically, the relief opening 22 is located on one side of the drinking tray 20 and close to the middle of the drinking tray 20. That is, the relief opening 22 is formed by the edge of one side of the drinking tray 20 being recessed towards the center of the drinking tray 20.

[0038] The clearance opening 22 is a notch 616 formed by a recess from the edge of the drinking tray 20 towards the center. Thus, when the water inlet pipe 42 extends downward from the mounting part 12, it passes through the clearance opening 22 and continues downward into the purified water tank 30. In this way, by providing the clearance opening 22, the water inlet pipe 42 can extend below the drinking tray 20 without having to go around the edge of the drinking tray 20, making the overall structure more compact. At the same time, the provision of the clearance opening 22, compared to opening a hole in the drinking tray 20, ensures the structural strength of the drinking tray 20.

[0039] Please see Figure 7 The water tray 20 has a disc-shaped structure, with a drinking area formed on its upper surface. Specifically, the upper surface of the water tray 20 has a water-holding trough 21, which is used to collect the water flow from the pump body 41 and provide drinking water for the pet. Furthermore, in this embodiment, the water tray 20 is detachably mounted on the support part 11. When cleaning is required, the water tray 20 can be removed for cleaning, and then the clean water tank 30 can be removed as well. Since both the water tray 20 and the clean water tank 30 have relatively small size and weight compared to the overall structure of the device, they facilitate cleaning operations for the user.

[0040] Specifically, please refer to Figure 7 To achieve the detachable connection of the water tray 20, the support part 11 is provided with a mounting shaft 113. The pet water fountain 100 also includes a mounting member 50, which connects to the water tray 20 and has a second slot 51. The mounting shaft 113 is engaged in the second slot 51. Specifically, one side of the mounting member 50 has a second slot 51 that is approximately U-shaped or arc-shaped, and the other side of the mounting member 50 is connected to the water tray 20. The opening size of the second slot 51 is slightly smaller than the diameter of the mounting shaft 113. During installation, the water tray 20 is pushed horizontally so that, under a certain pressure, the area of ​​the mounting member 50 with the second slot 51 deforms, causing the mounting member 50 to engage in the second slot 51. In this way, the mounting member 50 clamps the mounting shaft 113. When it is necessary to remove the water tray 20, the user can pull the water tray 20 horizontally to remove it. Thus, the water tray 20 is mounted on the base 10 by the mounting component 50. Compared with the method of directly opening the second slot 51 on the water tray 20, the installation strength of the water tray 20 on the base 10 can be increased.

[0041] Specifically, when connecting the mounting component 50 and the drinking tray 20, the mounting component 50 is provided with a clamping groove 52, the drinking tray 20 is located in the clamping groove 52, and the drinking tray 20 and the mounting component 50 are also connected by threads, which is equivalent to having clamping walls on both the upper and lower sides of the drinking tray 20. Compared with the method of connecting the mounting component 50 and the drinking tray 20 by threads on only one side, the double-sided clamping method further ensures the connection strength between the mounting component 50 and the drinking tray 20.

[0042] Please see Figures 1 to 4 as well as Figures 8 to 13 To achieve the effect of running water, the pet water fountain also includes a circulation pump 60, which is located in the mounting part 12. The circulation pump 60 is used to draw water from the water tray 20 and send it back to the water tray 20. By setting the circulation pump 60 on the mounting body above the water tray 20, the circulation pump 60 can draw water from the water tray 20 and discharge it back to the water tray 20, so that the water can flow on the water tray 20, realize the circulation of water, and make the water in the water tray 20 running water to satisfy the pet's drinking preferences.

[0043] Please refer to Figures 11 to 13The circulating pump 60 includes a mounting bracket 61, a first drive motor 62 mounted on the mounting bracket 61, and an impeller 63 connected to the output end of the first drive motor 62. The mounting bracket 61 has a downwardly extending mounting post 611, the interior of which forms a mounting cavity 612. The impeller 63 is located in the mounting cavity 612, and the mounting post 611 has a drain outlet 613. The mounting bracket 61 has a drainage channel 64 located outside the mounting post 611. The drain outlet 613 and the drainage channel 64 are connected. The drainage channel 64 discharges the water transported by the impeller 63 in a spiral manner. That is, the drainage channel 64 is arranged along the tangential direction of the mounting post 611. Specifically, the mounting cavity 611... 12 has an opening (i.e., water inlet 68) connected to the water tank 21 of the drinking tray 20. Driven by the first drive motor 62, the impeller 63 rotates in the mounting cavity 612, and the water inlet 68 draws water from the drinking tray 20. The water is centrifugally thrown out by the impeller 63 as it rotates into the spiral-designed drainage channel 64. Compared with the traditional radially arranged drainage pipe, the drainage channel 64 can smoothly convert the potential energy of the centrifugal water flow thrown out by the impeller 63 into the kinetic energy of the water flowing forward along the drainage channel 64, effectively eliminating the violent impact caused by the radial drainage method, making the water flow gentler and avoiding water splashing, so that the water can be smoothly discharged onto the drinking tray 20.

[0044] Furthermore, to achieve a smoother water flow, conforming to the centrifugal flow characteristics generated by the high-speed rotation of the impeller 63, and avoiding energy loss due to water impacting the inner wall of the mounting cavity 612, the inner wall of the mounting column 611 in this embodiment is provided with a notch 616. The notch 616 is connected to the drain outlet 613, and the drain outlet 613 is located within the circumferential extension range of the notch 616 along the inner wall of the mounting column 611. That is, the notch 616 forms a smooth, tangential guiding slope on the inner wall of the mounting cavity 612. At this time, the rotation center of the impeller 63 can be eccentric within the mounting cavity 612. When the impeller 63 rotates at high speed, the centrifugal force will throw the water out in all directions and flow out along the side wall of the notch 616, forming a stable "vortex" in the pump's mounting cavity 612. When the water flows along the inner wall vortex at high speed and flows to the notch 616, the side wall of the notch 616 forms the flow transition surface of the drainage channel 64. If the mounting cavity 612 is shaped like a regular cylinder, when the water is thrown out by the impeller 63, it will rotate at high speed along the inner wall of the mounting column 611 and generate a violent swerve, causing the water to directly hit the inner wall, forming a lot of turbulence and noise, and also wasting the kinetic energy of the water.

[0045] It should be noted that, in this embodiment, the blades 631 of the impeller 63 are arranged radially along the mounting post 611, and the two sides of the impeller 63 along the radial direction of the mounting post 611 have gaps with the inner wall of the mounting post 611 and the outer wall of the connecting shaft of the impeller 63, respectively, so that the water flow can be sucked up and thrown out into the mounting cavity 612.

[0046] Please see Figure 13 To facilitate the installation of the first drive motor 62, the mounting bracket 61 in this embodiment includes a detachably connected upper bracket 614 and lower bracket 615. The upper bracket 614 is used to mount the first drive motor 62, and the lower bracket 615 is provided with a mounting post 611 and a mounting cavity 612. The circulating pump 60 also includes a first sealing sleeve 67, which is sandwiched between the upper bracket 614 and the lower bracket 615. The output shaft 621 of the first drive motor 62 passes through the first sealing sleeve 67. Thus, when installing the first drive motor 62, the first drive motor 62 and the upper bracket 614 can be bolted together as a whole, and the upper bracket 614 and the lower bracket 615 can also be bolted together as a whole. At the same time, the first sealing sleeve 67 is sandwiched between the upper bracket 614 and the lower bracket 615, which realizes the assembly of the entire circulating pump 60. At the same time, the first sealing sleeve 67 is sleeved on the outside of the drive shaft to achieve the sealing of the entire mounting bracket 61.

[0047] Please see Figures 1 to 4 as well as Figure 7 In this embodiment, when circulating water, the water tank 21 of the drinking tray 20 includes a deep water zone 211 and a shallow water zone 212 with different depths. The circulation pump 60 is set corresponding to the deep water zone 211, that is, the projection of the circulation pump 60 in the vertical direction is located in the deep water zone 211. Since the deep water zone 211 is deeper, the water inlet end 68 of the circulation pump 60 can be completely submerged in the water flow, preventing the circulation pump 60 from sucking up air.

[0048] Furthermore, in order to provide clean water to the animal during circulation, the mounting body of this embodiment is provided with a connecting frame 14, which extends into the deep water zone 211 and has a gap with the bottom wall of the deep water zone 211 to avoid obstructing the flow of water to the side of the circulation pump 60. Along the length of the deep water zone 211 (i.e., along the left-right direction of the entire pet water fountain), the circulation pump 60 is located at one end of the connecting frame 14. The pet water fountain 100 of this embodiment also includes a filter screen 90, which is located at the other end of the connecting frame 14 and contacts the bottom wall of the deep water zone 211. The filter screen 90 is used to filter the water flow when the circulation pump 60 pumps the water. Specifically, the filter screen 90 is located at one end of the deep water zone 211. When the circulation pump 60 pumps in water, the water flow first passes through the filter screen 90. The filter screen 90 blocks pet hair and other impurities before flowing to the side of the circulation pump 60. The circulation pump 60 pumps out the filtered water and discharges it, thus providing flowing pure water. At the same time, the connecting frame 14 and the circulation pump 60 are set to correspond to the deep water zone 211, and the shallow water zone 212 can be used as an exposed area with nothing blocking it, making it convenient for the pet to drink water.

[0049] It should be noted that you should refer to [link / reference]. Figure 8 and Figure 9 In order to provide pets with clean water as much as possible, the filter screen 90 is detachably located at one end of the connecting frame 14, for example, by snap-fit ​​or plug-in. This allows the filter screen 90 to be removed and replaced or cleaned after a period of water circulation when a lot of hair or other dirt adheres to it, so as to ensure the cleanliness of the water flow during subsequent circulation.

[0050] Further, please refer to Figure 7 To better achieve the flow of water, i.e., to better realize the effect of "living water", the drinking tray 20 has a protrusion 23 in the shallow water area 212. The protrusion 23 extends along the length of the deep water area 211. The length of the protrusion 23 is less than the length of the connecting frame 14, and the width of the protrusion 23 in the front-to-back direction is less than the width of the shallow water area 212 in the front-to-back direction. The side of the protrusion 23 facing the deep water area 211 is connected to one side wall of the deep water area 211. In this way, the protrusion 23 can block the flow of water between the shallow water area 212 and the deep water area 211 in the front-to-back direction, so that the water overflowing from the deep water area 211 must bypass the protrusion 23 to enter the outside of the shallow water area 212. That is, it can realize the slow flow of water in the shallow water area 212, and flow from the side of the deep water area 211 without the circulation pump 60 to the deep water area 211, and then be sucked in again by the circulation pump 60. In this way, a circulating living water effect is formed. Figure 3 As shown by the arrow in the image.

[0051] Furthermore, the outlet 69 of the circulation pump 60 in this embodiment is also located above the deep water zone 211. In this way, when the water is discharged from the circulation pump 60, it can be directly discharged into the deep water zone 211, ensuring that the deep water zone 211 always has sufficient water volume and sufficient depth. The inlet 68 of the circulation pump 60 can always be submerged in the water flow, avoiding the circulation pump 60 from experiencing dry suction, thus achieving the effect of protecting the circulation pump 60. At the same time, since the outlet of the circulation pump 60 is located in the deep water zone 211, when the pet drinks in the shallow water zone 212, it can also prevent water from splashing onto the pet's fur or whiskers, thus avoiding causing the pet's aversion.

[0052] Specifically, please refer to Figure 7 In this embodiment, the deep water zone 211 is configured along its length (i.e., the left-right direction of the entire pet water fountain). The deep water zone 211 includes a first segment 2111 and a second segment 2112 with different widths. The width of the second segment 2112 in the front-back direction is greater than the width of the first segment 2111. The connecting frame 14 is positioned above the first segment 2111. The circulation pump 60 is positioned corresponding to the second segment 2112, and the second segment 2112 is circular. That is, the first segment 2111 of the deep water zone 211 receives water flowing from the shallow water zone 212. By positioning the circulation pump 60 in the wider second segment 2112 and making the second segment 2112 circular, i.e., the second segment 2112 has smooth sidewalls, the water can flow smoothly along the inner wall of the second segment 2112, avoiding dead zones in the water flow when the circulation pump 60 pumps.

[0053] Further, please refer to Figure 1 , Figure 2 as well as Figures 4 to 9 To facilitate the drainage of water after long-term use, the pet water fountain also includes a wastewater tank 80 and a drain valve 70. The wastewater tank 80 and the clean water tank 30 are arranged side by side on the support part 11, and the drain valve 70 is located on the mounting part 12. The wastewater outlet 24 of the drinking tray 20 is connected to the cavity of the wastewater tank 80. The drain valve 70 is used to open or close the wastewater outlet 24. When there is dirt deposited on the drinking tray 20, the drain valve 70 opens the wastewater outlet 24 on the drinking tray 20, and the wastewater is discharged into the wastewater tank 80. At the same time, it can also carry impurities into the wastewater tank 80, preventing impurities from accumulating in the drinking tray 20 and breeding bacteria. After the wastewater is discharged, the next clean water is discharged, which makes it convenient for the pet to drink.

[0054] Please see Figures 14 to 17The diagram below shows the structure of the drain valve 70 in this embodiment. The drain valve 70 includes a second drive motor 71, a pressing member 72, an elastic member 73, and a valve body 74. The pressing member 72 is connected to the output end of the second drive motor 71 and abuts against the valve body 74. The two ends of the elastic member 73 act on the mounting part 12 and the valve body 74, respectively.

[0055] Specifically, the second drive motor 71 provides driving force, and the pressing member 72 can move in a predetermined direction under the drive of the second drive motor 71, and the pressing member 72 is always in contact with the valve body 74. In the initial state (i.e., the state where drainage is not required), the pressing member 72 presses against the valve body 74, causing the valve body 74 to close the drain port 24; when drainage is required, the second drive motor 71 operates, driving the pressing member 72 to rotate counterclockwise, that is, driving the pressing member 72 away from the valve body 74. Under the elastic force of the elastic member 73, the valve body 74 moves upward, causing the valve body 74 to disengage from the drain port 24, thereby opening the drain port 24 and allowing sewage to be discharged. When it is necessary to close the drain port 24, the second drive motor 71 drives the pressing member 72 to rotate clockwise, and the pressing member 72 drives the valve body 74 to move downward, the valve body 74 seals the drain port 24, and re-seals the drain port 24. Therefore, through the cooperation of the second drive motor 71 and the elastic element 73, the drain valve 70 can be automatically controlled, making operation convenient. The elastic element 73 can be a spring, elastic rubber, etc., and in this embodiment, a spring is preferred.

[0056] Specifically, please refer to Figure 17 The diagram below shows the structure of the valve body 74 in this embodiment. The valve body 74 includes an abutment frame 741, a connecting frame 742, and a second sealing sleeve 743. The abutment frame 741 abuts against the pressing member 72, and the second sealing sleeve 743 is clamped between the abutment frame 741 and the connecting frame 742.

[0057] Specifically, the abutment frame 741 is used to receive the pressing force of the pressing member 72. The connecting frame 742 is connected to the abutment frame 741. The connecting frame 742 and the abutment frame 741 transmit the thrust to the second sealing sleeve 743. At the same time, the second sealing sleeve 743 is clamped and fixed between the abutment frame 741 and the connecting frame 742. In this way, the installation of the second sealing sleeve 743 is realized, so that the deformation of the second sealing sleeve 743 can block the drain outlet 24.

[0058] That is, when the second sealing sleeve 743 moves upward, the second sealing sleeve 743 opens the drain port 24; when the second sealing sleeve 743 moves downward, the drain port 24 closes. Thus, by setting the valve body 74 into three parts, it is convenient to set the materials of the abutment frame 741, connecting frame 742, and second sealing sleeve 743 as needed. A material with a certain degree of hardness can be used to cooperate with the elastic element 73 to press the elastic element 73, while the second sealing sleeve 743 can be made of a deformable material to ensure the sealing of the drain port 24.

[0059] Specifically, please refer to Figure 17 When sealing the drain outlet 24, the second sealing sleeve 743 includes a clamping part 744 and a sealing part 745. The sealing part 745 is used to seal the outside of the drain outlet 24. Specifically, the sealing part 745 is bowl-shaped, and the clamping part 744 is clamped between the abutment frame 741 and the connecting frame 742, thereby fixing the second sealing sleeve 743. By setting the sealing part 745 to be bowl-shaped, that is, the sealing part 745 has a shape similar to a bowl with a concave center, the bowl-shaped sealing part 745 can generate elastic deformation when pressure is applied, better fit the edge of the drain outlet 24, thereby ensuring the sealing effect and preventing water leakage from the drinking tray 20 during normal water supply.

[0060] Please see Figure 15 When setting the drain valve 70, the bottom of the mounting part 12 is provided with a mounting structure 122. The mounting structure 121 extends towards the drinking tray 20. The elastic element 73 is located in the mounting structure 122, and the abutment frame 741 is slidably located on the mounting structure 122. That is, the mounting structure 122 provides a mounting position for the elastic element 73 and also provides a guide for the sliding of the abutment frame 741. At this time, the abutment frame 741 can slide along the mounting structure 122, thereby making the up and down movement of the valve body 74 more stable.

[0061] Specifically, please refer to Figure 15 The diagram shows the structure of the installation structure 122 in this embodiment, which includes an outer cylinder 1221, an inner cylinder 1222, and a connecting wall 1223 connecting the outer cylinder 1221 and the inner cylinder 1222. An installation space 1224 is defined between the outer cylinder 1221, the inner cylinder 1222, and the connecting wall 1223. An elastic member 73 is provided in the installation space 1224, and an abutment frame 741 is slidably provided in the inner cylinder 1222.

[0062] Specifically, the outer cylinder 1221 has a cylindrical structure, and the inner cylinder 1222 also has a cylindrical structure. The inner cylinder 1222 is located inside the outer cylinder 1221. The connecting wall 1223 connects the lower ends of the outer cylinder 1221 and the inner cylinder 1222, fixing the outer cylinder 1221 and the inner cylinder 1222 together for the elastic element 73 to abut against. The outer cylinder 1221, the inner cylinder 1222, and the connecting wall 1223 together form an annular installation space 1224. The elastic element 73 (such as a spring) is set in the installation space 1224, so that the installation space 1224 plays a limiting and accommodating role for the elastic element 73, preventing the elastic element 73 from shifting during compression and reset, and ensuring that the elastic element 73 can stably apply force to the valve body 74. At the same time, the inner cylinder 1222 has a certain extension length in the vertical direction, which can guide the sliding extension and retraction of the abutment frame 741.

[0063] Further, please refer to Figure 17 To ensure the stability of the valve body 74 during vertical sliding in the mounting structure, the abutment frame 741 includes a first sliding part 746 and a second sliding part 747. The first sliding part 746 protrudes radially from the second sliding part 747 and is slidably disposed relative to the inner wall of the outer cylinder 1221. The second sliding part 747 is slidably disposed relative to the inner wall of the inner cylinder 1222. In other words, the abutment frame 741 has two sliding engagement parts: the first sliding part 746 is slidably engaged with the inner wall of the outer cylinder 1221, and the second sliding part 747 is slidably engaged with the inner wall of the inner cylinder 1222. Thus, the abutment frame 741 is guided by both the outer cylinder 1221 and the inner cylinder 1222 during sliding, which makes it more stable during vertical sliding and effectively avoids the abutment frame 741 tilting during sliding, thereby ensuring the reliability of the drain valve 70.

[0064] Please see Figure 1 and Figure 2 In some embodiments of the present invention, the wastewater tank 80 is also detachably mounted on the base 10. This allows the user to easily remove the wastewater tank 80 from the base 10 for cleaning, facilitating daily maintenance and cleaning, and ensuring the hygiene of the water dispenser.

[0065] Further, please refer to Figure 7 When a drain outlet 24 is provided on the water dish 20, the drain outlet 24 is located in the deep water area 211, giving the deep water area 211 a larger volume. Simultaneously, water can flow from the shallow water area 212 to the deep water area 211, carrying dirt to the deep water area 211, and finally discharging it from the drain outlet 24. Specifically, the circulation pump 60 is also located in the deep water area 211, and is positioned opposite the drain valve 70, to achieve water circulation in the water dish 20, providing a flowing water effect for easy drinking by pets.

[0066] Furthermore, corresponding to the setting of the drain valve 70, the deep water zone 211 in this embodiment also includes a third section 2113. The third section 2113, the first section 2111, and the second section 2112 are arranged sequentially. Along the front-back direction, the width of the third section 2113 and the second section 2112 are both greater than the width of the first section 2111. The drain outlet 24 is located in the third section 2113, and the first section 2111 is circular. In this way, when draining, the water flow can flow along the smooth circular surface and be discharged from the drain outlet 24 into the sewage tank 80, avoiding the occurrence of dead flow corners. That is, the third section 2113 and the first section 2111 are both arranged in a circular shape, so that the water flow can flow smoothly in the third section 2113 and the first section 2111, avoiding the occurrence of dead flow corners.

[0067] Thus, in this embodiment, when the water flows in circulation, the circulation pump 60 discharges the water to the second section 2112, then flows around the convex 23 to the third section 2113. When the water flows from the third section 2113 to the first section 2111, it is filtered by the filter screen 90, and then flows to the second section 2112.

[0068] Please see Figures 1 to 3 as well as Figure 18 In one embodiment of the present invention, in order to facilitate the addition of water to the water tank 30, the mounting part 12 is provided with a water inlet 121, and the base 10 also includes a water guiding structure 13. The water guiding structure 13 is installed on the mounting part 12 and communicates between the water inlet 121 and the inner cavity of the water tank 30. When the user needs to add water to the water tank 30, he / she only needs to pour clean water along the water inlet 121 without having to remove the entire water tank 30, thus facilitating the water addition operation.

[0069] Specifically, the water guiding structure 13 includes a guide section 131 and a connecting section 132 from top to bottom. The guide section 131 is funnel-shaped, with its large end opening corresponding to the water inlet 121. The connecting section 132 is a tubular structure, with its lower end connected to the water inlet of the water tank 30. Thus, the funnel-shaped guide section 131 has a larger opening area. When water is poured in, the water flows into the guide section 131, and the water gathers along the guide section 131 and flows into the water tank 30 through the connecting section 132, avoiding splashing.

[0070] Furthermore, to prevent dirt from falling into the water tank 30 during daily use, the pet water fountain also includes a cover 15. The cover 15 is closable and located at the water inlet 121. In one embodiment, the cover 15 can be directly removed to open the water inlet 121. Alternatively, in another embodiment, it can be connected to the mounting part 12 by means of hinges, buckles, etc. When opened, the water inlet 121 is exposed, and when closed, the water inlet 121 is covered to prevent foreign objects from entering the water tank 30.

[0071] The following describes the working process of a water-electricity separation pet water dispenser according to a specific embodiment of the present invention: (1) When the drinking water tray 20 is in the water supply state, the valve body 74 of the drain valve 70 closes the drain port 24 under the pressing action of the pressing member 72, that is, the sealing part 745 of the second sealing sleeve 743 is sealed at the drain port 24, and at the same time, the clean water tank 30 stores clean drinking water.

[0072] (2) When it is necessary to provide drinking water for the pet, the pump body 41 is started. The pump body 41 pumps the clean water in the water tank 30 to the water container 21 in the drinking tray 20. The water first enters the deep water area 211. When the water level in the deep water area 211 reaches a certain height, the water overflows into the shallow water area 212. The pet can drink water in the deep water area 211 or the shallow water area 212.

[0073] (3) When the water in the drinking tray 20 deteriorates after a period of use, and dirt such as hair accumulates, requiring drainage and water replacement, the second drive motor 71 is started. The second drive motor 71 drives the pressing member 72 to rotate in the direction of disengaging the valve body 74. Under the elastic force of the elastic member 73, the sealing part 745 of the second sealing sleeve 743 disengages from the drain port 24, opening the drain port 24. At this time, the sewage in the water tank 21 of the drinking tray 20 flows out from the drain port 24 under the action of gravity, and at the same time, the dirt in the drinking tray 20 is carried away and flows into the sewage tank 80 located below the drinking tray 20 for collection.

[0074] (4) After the sewage is discharged, the second drive motor 71 drives the pressing member 72 to apply pressing force to the valve body 74 and overcome the elastic force of the elastic member 73. At this time, the sealing part 745 of the second sealing sleeve 743 re-seals the sewage outlet 24, and the sewage outlet 24 is closed. After that, the pump body 41 starts again and pumps the clean water in the clean water tank 30 to the drinking tray 20 for the pet to continue drinking.

[0075] (5) When the water bowl 20 gets dirty after long-term use, the user can remove the water bowl 20, the wastewater tank 80 and the clean water tank 30 from the base 10, pour out the collected wastewater and clean the wastewater tank 80, and clean the water bowl 20 and the clean water tank 30, and then put them back on the base 10 for continued use, thereby ensuring the cleanliness of the water supply for the pet.

[0076] The aforementioned pet water fountain 100 with water and electricity separation, by setting the base 10 as the support part 11 and the mounting part 12, and by centrally installing all the live parts with drive motors, including the pump body 41, the circulation pump 60, and the drain valve, on the mounting part 12 located above the water tray 20, the drive motors in the live parts will not come into direct contact with the water, thereby improving the safety of the entire pet water fountain. The circulation pump 60 continuously pumps the water in the water tray 20 to form a circulating water flow, turning the "stagnant water" in the traditional water tray 20 into flowing "living water", which is more appealing to pets. The drain valve 70 and the wastewater tank 80, with the drain outlet 24 located in the deep water area 211, help to remove dirt. When the water quality in the water tray 20 deteriorates, the drain valve 70 automatically opens to discharge wastewater into the wastewater tank 80, preventing dirt (such as pet hair, dander, and food residue) from accumulating in the water tray 20 for a long time and forming a biofilm and breeding bacteria, thereby ensuring the cleanliness of the pet's drinking water.

[0077] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
