[0045] This utility model provides a split-type water tank for separating clean and dirty water and a pet water dispenser. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0046] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] Example 1

[0048] Please refer to Figures 1 to 4 As shown, this embodiment discloses a split-type clean and dirty water tank, comprising:

[0049] The outer water tank 10 is equipped with a clean water chamber 11 with an open top.

[0050] The inner water tank 20 is detachably installed inside the water purification chamber 11. The inner water tank 20 is provided with a circulating water chamber 21 that communicates with the water purification chamber 11.

[0051] A one-way water supply valve 30 is located on the bottom side of the circulating water chamber 21 to restrict water from flowing unidirectionally from the clean water chamber 11 to the circulating water chamber 21.

[0052] The split-type clean and dirty water tank of this embodiment can be applied to pet water fountains. By setting up independent clean water chamber 11 and circulating water chamber 21, the circulating water containing impurities after being drunk by the animal cannot flow into the clean water chamber 11 under the action of the one-way water supply valve 30, thereby avoiding cross-contamination between clean water and circulating water. During operation, only the water in the circulating water chamber 21 participates in the circulation. The water capacity of the circulating water chamber 21 is small, so the filter element in the inner water tank 20 can achieve high-efficiency filtration and greatly extend the service life of the filter element.

[0053] Furthermore, in this embodiment, the outer water tank 10 and the inner water tank 20 are designed as separate nested structures. The inner water tank 20 can be completely disassembled, which makes it convenient for users to clean. Moreover, by separating the outer water tank 10 and the inner water tank 20, users can clean any part of the interior of the outer water tank 10 and the inner water tank 20, thereby preventing dead corners from being uncleaned.

[0054] In this embodiment, the one-way water supply valve 30 is located on the bottom side of the circulating water chamber 21 to make fuller use of the purified water in the purified water chamber 11.

[0055] Please refer to Figure 2 and Figure 3 In this embodiment, the outer water tank 10 and the inner water tank 20 are connected by a snap-fit. The outer bottom of the outer water tank 10 is provided with a slot 12. The inner bottom of the inner water tank 20 is provided with a snap 22 that cooperates with the slot 12. Through the cooperation of the snap 22 and the slot 12, the outer water tank 10 and the inner water tank 20 can be quickly installed and disassembled.

[0056] It should be noted that the snap-fit ​​connection between the outer water tank 10 and the inner water tank 20 in this embodiment is only one preferred implementation method. In other embodiments, the two can also be connected by threaded connection, plug-in connection, etc., and are not limited to the snap-fit ​​connection in this embodiment. These equivalent variations or substitutions are all included within the scope defined by the claims of this application.

[0057] Furthermore, to facilitate the installation and positioning of the inner water tank 20, the split-type clean and dirty water tank of this embodiment also includes a positioning component; the positioning component includes a first magnet 13 located below the slot 12 and a second magnet 23 located inside the buckle 22. The first magnet 13 and the second magnet 23 magnetically attract each other. During the installation of the inner water tank 20, due to the magnetic attraction between the first magnet 13 and the second magnet 23, the buckle 22 can be guided to align with the slot 12, reducing the difficulty of alignment. Moreover, after installation, the magnetic attraction makes the two fit more tightly, preventing loosening.

[0058] Please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the one-way water supply valve 30 is a ball valve 32; the inner water tank 20 is provided with a channel 24 that runs vertically and communicates with the circulating water chamber 21. The ball valve 32 can float up and down along the channel 24. The lower end of the channel 24 is connected to an inlet 25 that communicates with the clean water chamber 11. The ball valve 32 can move upward to open the inlet 25, and the ball valve 32 can move downward to block the inlet 25. When the pressure of the circulating water chamber 21 and the clean water chamber 11 is balanced, the ball valve 32 blocks the inlet 25 under the action of gravity to prevent the circulating water in the circulating water chamber 21 from entering the clean water chamber 11 and causing contamination of the clean water in the clean water chamber 11. When the water level in the circulating water chamber 21 drops, a pressure difference is generated between the circulating water chamber 21 and the clean water chamber 11. The ball valve 32 is lifted by the high pressure water in the clean water chamber 11 and opens the inlet 25. The water in the clean water chamber 11 enters the circulating water chamber 21 through the inlet 25. The structure is ingenious.

[0059] Furthermore, the ball valve 32 can be made of food-grade plastic material, and its vertical floating stroke is 5-30mm.

[0060] Example 2

[0061] Please refer to Figure 5 As shown, the one-way water supply valve 30 in this embodiment adopts a duckbill silicone valve 31. The water inlet of the duckbill silicone valve 31 faces the clean water chamber 11, and the water outlet faces the circulating water chamber 21. When the pressure of the circulating water chamber 21 and the clean water chamber 11 is balanced, the duckbill silicone valve 31 closes to prevent the circulating water in the circulating water chamber 21 from entering the clean water chamber 11 and causing contamination of the clean water in the clean water chamber 11. When the water level in the circulating water chamber 21 drops, a pressure difference is generated between the circulating water chamber 21 and the clean water chamber 11, and the duckbill silicone valve 31 opens, allowing the water in the clean water chamber 11 to enter the circulating water chamber 21 through the duckbill silicone valve 31.

[0062] It should be noted that the use of a duckbill silicone valve 31 for the one-way water supply valve 30 in this embodiment is only one preferred implementation. In other embodiments, the one-way water supply valve 30 may also use a cross silicone valve, etc., and is not limited to the duckbill silicone valve 31 in this embodiment. These equivalent variations or substitutions are all included within the scope defined by the claims of this application.

[0063] Example 3

[0064] Please refer to Figures 6 to 9 As shown, this embodiment also discloses a pet water fountain that separates clean water from dirty water, including:

[0065] Example 1: Split-type clean and dirty water tank;

[0066] The top cover 40 is detachably installed on the open end of the outer water tank 10. The top cover 40 is provided with a return port 41 that runs vertically through the top and bottom. The inner water tank 20 is located below the return port 41.

[0067] The filter element 50 is located between the return port 41 and the circulating water chamber 21 and is used to filter the return water.

[0068] The water outlet 60 includes a water outlet structure 61 that extends upward through the return port 41 and flows toward the top cover 40;

[0069] A water pump 70 is located on the bottom side of the circulating water chamber 21 and is used to pump water from the circulating water chamber 21 to the water outlet 60.

[0070] In this embodiment of the pet water fountain with clean and dirty separation, during operation, the water pump 70 draws water from the circulating water chamber 21 to the water outlet 60, and then the water is discharged towards the top cover 40 through the water outlet structure 61 of the water outlet 60. Pets such as cats and dogs can drink the water on the top cover 40. The water on the top cover 40 can also flow back through the return port 41. The returned water is filtered by the filter element 50 and then flows back into the circulating water chamber 21, realizing water circulation and filtration.

[0071] In this embodiment, the split-type clean and dirty water tank adopts a split nested outer water tank 10 and inner water tank 20. Moreover, the clean water chamber 11 of the outer water tank 10 and the circulating water chamber 21 of the inner water tank 20 are independent of each other. When the circulating water level in the circulating water chamber 21 drops, the ball valve 32 floats up and opens the inlet 25, allowing the clean water in the clean water chamber 11 to flow into the circulating water chamber 21 to replenish the circulating water chamber 21. The advantage of using the ball valve 32 is that the circulating water containing impurities after being drunk by animals cannot flow into the clean water chamber 11, thereby avoiding cross-contamination between clean water and circulating water. In addition, during the operation, only the water in the circulating water chamber 21 participates in the circulation. The water capacity of the circulating water chamber 21 is small, so the filter element 52 of the filter element 50 can achieve high-efficiency filtration and greatly extend the service life of the filter element 52.

[0072] Please refer to Figure 7 The top cover 40 and the outer water tank 10 can be connected by a detachable structure, so that the two can be separated for easy cleaning by the user.

[0073] Furthermore, the top cover 40 has an upwardly protruding baffle 42 in the middle, and the return port 41 is located inside the baffle 42; the top cover 40 has an upwardly protruding side skirt 43 at its edge, and a first water trough 44 for holding water is formed between the side skirt 43 and the baffle 42. The water flowing out of the water outlet structure 61 can flow into the first water trough 44 to form a certain water level, which is convenient for pets such as cats and dogs to drink water.

[0074] Please refer to Figure 9 Since the first water tank 44 is relatively deep, pet hair, snack particles, and other contaminants from cats and dogs will accumulate at the bottom of the first water tank 44. These contaminants cannot flow in from the return port 41. Therefore, in this embodiment, multiple drain holes 45 are provided on the top cover 40. The drain holes 45 are arranged around the baffle plate 42 and are located above the filter element 50. In this embodiment, the drain holes 45 are round holes and there are three of them. Pet hair, snack particles, and other contaminants from cats and dogs can be discharged into the filter element 50 through the drain holes 45. After being filtered by the filter element 50, the contaminants in the first water tank 44 can be prevented from accumulating, so that cats and dogs can drink unclean water.

[0075] Please refer to Figure 7 The filter element 50 includes a frame 51 that can be detachably installed on the top of the inner side of the inner water tank 20, and a filter element 52 disposed in the frame 51. The bottom of the frame 51 is provided with a vertically penetrating connecting part 53. The lower end of the water outlet 60 is inserted into the upper end of the connecting part 53. The water outlet end of the water pump 70 is connected to the lower end of the connecting part 53. With this design, the return water is filtered through the filter element 52 first, and then flows back to the circulating water chamber 21. Moreover, after the water pump 70 draws the circulating water out of the circulating water chamber 21, it first enters the water outlet 60 through the connecting part 53, and then is discharged from the water outlet structure 61 of the water outlet 60.

[0076] Please refer to Figure 7 and Figure 8 The water outlet component 60 also includes a housing 62. The water outlet structure 61 includes a support plate 611 connected to the upper end of the housing 62, a surrounding plate 612 surrounding the support plate 611, and an inner cover 613 detachably installed in the middle of the inner side of the support plate 611. A second water tank 63 is formed inside the surrounding plate 612. The surrounding plate 612 is provided with a number of side drain holes 64 distributed circumferentially. The inner cover 613 is provided with a fountain-type spray hole 65 that connects the inner cavity of the housing 62 and the second water tank 63. The fountain-type spray hole 65 can spray water upward like a fountain. After the water falls into the second water tank 63, it is discharged in a faucet-like manner through the side drain holes 64 and then falls onto the first water tank 44. For pets such as cats and dogs, they can choose to drink water from the fountain, the faucet, or the water in the second water tank 63. These three drinking methods can adapt to pets of different heights and their preferred drinking habits.

[0077] The water outlet 60 can also be equipped with a filter structure such as filter cotton or filter screen. As the usage time increases, the filter structure and the filter element 52 of the filter element 50 will accumulate a lot of hair, debris, bacteria, etc., so they need to be replaced regularly. However, users sometimes find it difficult to remember the replacement date of the filter structure and filter element 52, which causes great trouble to users. Therefore, this embodiment has a rotatable dial 614 on the inner cover 613. The upper surface of the inner cover 613 has several circumferentially distributed text markings 615. The dial 614 has observation holes 616 corresponding to the positions of any two text markings 615. This application sets a rotatable dial 614 and prints date and other text markings 615 on the inner cover 613. For example, the month markings of January, February, March, April, May, June, July, August, September, October, November, and December are printed sequentially on the upper surface of the inner cover 613 along the circumference. With the help of two linked observation holes 616, the new replacement date and the due date for replacement are displayed respectively. The replacement cycle is fixed at 2 to 3 months. When using it for the first time, one of the observation holes 616 of the dial 614 is turned to the usage date, and the other observation hole 616 will automatically display the date for replacement.

[0078] Example 4

[0079] Please refer to Figure 10 In this embodiment, the drain hole 45 is a strip-shaped hole and has three holes. Pet hair, snack particles and other pollutants can be discharged into the filter element 50 through the drain hole 45. The filter element 50 filters the pollutants and prevents them from accumulating in the first water tank 44, which would cause pets such as cats and dogs to drink unclean water.
