[0051] Combine the following Figures 1 to 12 The embodiments of the utility model are described.

[0052] The present embodiment relates to a drinking fountain with a clean and dirty water separation tank, which provides a clean water chamber 11 and a circulating water chamber 12 which are independent of each other, and circulates the water in the circulating water chamber 12 separately, thereby achieving efficient circulation filtration of return water (ie, sewage).

[0053] This embodiment provides two types of embodiments of a water dispenser with a clean and dirty water separation tank. The difference between the two types of embodiments is that the clean water chamber 11 and the circulating water chamber 12 are an integrated structure, or the clean water chamber 11 and the circulating water chamber 12 are separable.

[0054] Reference Figures 1 to 4 The first embodiment of the water dispenser with a clean and dirty water separation tank comprises:

[0055] The water tank 1 is provided with a clean water chamber 11 and a circulating water chamber 12, a water opening 13 is provided between the clean water chamber 11 and the circulating water chamber 12, and the water opening 13 connects the clean water chamber 11 and the circulating water chamber 12;

[0056] A top cover 2 covers the upper opening of the water tank 1 , and a reflux port 21 and a water outlet 22 are provided on the top cover 2;

[0057] A filter element 3 is provided between the reflux port 21 and the circulating water chamber 12 and is used for filtering the reflux water;

[0058] A water pump 4 is provided at the bottom side of the circulating water chamber 12, and a water outlet end of the water pump 4 is connected to a water outlet pipe 41 connected to the water outlet 22;

[0059] The one-way water supply valve 5 is arranged at the water outlet 13, which limits water to flow from the clean water chamber 11 to the circulating water chamber 12 in one direction, and allows water to flow from the clean water chamber 11 to the circulating water chamber 12 in one direction only when the water pressure in the clean water chamber 11 is greater than that in the circulating water chamber 12.

[0060] The drinking fountain with a clean and dirty water separation tank of the first embodiment of the utility model is provided with a clean water chamber 11 and a circulating water chamber 12 which are independent of each other in the water tank 1. Under the action of the one-way water supply valve 5, the circulating water containing impurities after being drunk by animals cannot flow into the clean water chamber 11, thereby avoiding the cross contamination of the clean water and the circulating water. In addition, during the operation, only the water in the circulating water chamber 12 participates in the circulation, and the water capacity of the circulating water chamber 12 is small, so the filter element can achieve high-efficiency filtration and greatly extend the service life of the filter element.

[0061] In this embodiment, the water inlet 13 is disposed at the bottom of the circulating water chamber 12 and the clean water chamber 11 to more fully utilize the clean water in the clean water chamber 11 .

[0062] In this embodiment, the water purification chamber 11 and the circulating water chamber 12 are an integrated structure;

[0063] The water dispenser also includes a return water guide groove 6, which is located between the top cover 2 and the water tank 1, and is connected to the top side of the water tank 1; a mounting groove 61 is provided on the return water guide groove 6, and the mounting groove 61 is located below the reflux port 21, the filter element 3 is arranged in the mounting groove 61, and a water outlet 611 is provided on the lower side of the mounting groove 61, and the water outlet 611 is connected to the circulating water chamber 12, and the water pump 4 is arranged on the bottom wall of the water tank 1.

[0064] After the water flows down from the return port 21, it passes through the filter element 3 of the lower mounting groove 61, and then flows out from the lower water port 611 into the circulating water chamber 12, and then is pumped out by the water pump 4 to the water outlet 22 of the top cover 2, thereby realizing water circulation. The provision of the return water guide groove 6 can conveniently guide the water to the circulating water chamber 12.

[0065] Furthermore, in order to conveniently clean the filter element 3, the water return guide groove 6 is detachably connected to the water tank 1 and / or the filter element 3 is detachably connected to the water return guide groove 6. The structure in which the filter element 3 is directly detachable from the water return guide groove 6 enables the filter element 3 to be conveniently removed separately for cleaning. The filter element 3 is arranged on the detachable water return guide groove 6, and the filter element 3 can also be conveniently removed for cleaning. At the same time, the surface of the water return guide groove 6 can also be conveniently cleaned. In this embodiment, the filter element 3 is detachably connected to the water return guide groove 6, and the water return guide groove 6 is detachably connected to the water tank 1.

[0066] In this embodiment, when the return water guide groove 6 is detachably connected to the water tank 1, the circulating water chamber 12 and the clean water chamber 11 are separated by a partition 14, and the return water guide groove 6 is arranged at the top opening of the clean water chamber 11. After the return water guide groove 6 is disassembled, the top opening of the clean water chamber 11 is opened, and the clean water chamber 11 of the water tank 1 can be cleaned conveniently.

[0067] The mounting groove 61 is located at the bottom side of the return water guide groove 6, and the water outlet 611 is arranged on the side wall of the mounting groove 61. The mounting groove 61 is arranged in the return water guide groove 6, and the filter element 3 is arranged in the mounting groove 61 at the bottom side, so that a larger accommodation space is reserved for the filter element 3, so as to install a larger filter element 3, and further improve the filtering efficiency.

[0068] Reference Figures 5 to 8 The difference between the drinking machine with a clean and dirty water separation tank in the second embodiment and the drinking machine with a clean and dirty water separation tank in the first embodiment is that the clean water chamber 11 and the circulating water chamber 12 are separable structures;

[0069] The water dispenser includes a return water guide groove 6, which is located between the top cover 2 and the water tank 1. The inner side of the water tank 1 is the clean water chamber 11. A sink hole 63 is formed on the bottom side of the return water guide groove 6. The inner cavity of the sink hole 63 is the circulating water chamber 12. The return water guide groove 6 is detachably connected to the water tank 1.

[0070] The filter element 3 is disposed on the water return guide groove 6 , the water pump 4 is disposed on the bottom wall of the sink hole 63 , and the water opening 13 is disposed on the side wall or the bottom wall of the sink hole 63 .

[0071] The filter element 3 and the circulating water chamber 12 are both arranged on the return water guide groove 6. When the detachable return water guide groove 6 is taken out, in addition to being able to conveniently clean the filter element 3, the circulating water chamber 12 and the clean water chamber 11 can also be conveniently cleaned.

[0072] The water openings are arranged on the side wall and the bottom wall of the sink hole, which can play the role of connecting the circulating water chamber and the clean water chamber. Figure 8 As shown), the water replenishment reaction of the clean water chamber to the circulating water chamber is faster, and the water replenishment can be carried out more timely.

[0073] Reference Figure 9-11 In all embodiments of the water dispenser with a clean and dirty water separation tank, the one-way water supply valve 5 can be one of the following four structures, or when the number of the one-way water supply valves 5 is more than two, the structure of the one-way water supply valve 5 can be one or more of the following four structures.

[0074] The first structure and the second structure of the one-way water supply valve 5 are respectively a cross silicone valve 51 and a duckbill silicone valve 52. The cross silicone valve 51 and the duckbill silicone valve 52 are both existing products on the market. Using the cross silicone valve 51 or the duckbill silicone valve 52 as the one-way water supply valve 5 can conveniently realize the lack of water in the circulating water chamber 12 by replenishing water through the clean water chamber 11.

[0075] The third structure of the one-way water supply valve 5 is a thin sheet 53, which covers the water port 13. One end of the thin sheet 53 is fixed and the other end is a free end. When the one-way water supply valve 5 is a thin sheet 53, the thin sheet 53 covers the water port 13. The two ends of the thin sheet 53 are the circulating water chamber 12 and the clean water chamber 11. When the water pressure in the circulating water chamber 12 drops, a pressure difference is generated between the circulating water chamber 12 and the clean water chamber 11. The clean water chamber 11 pushes the thin sheet 53 to deform, so that a water gap is formed between the thin sheet 53 and the water port 13. Water can flow into the circulating water chamber 12 from the water gap to replenish the circulating water chamber 12. The one-way water supply valve 5 adopts the structure of the thin sheet 53, which has the advantages of low cost and simple structure.

[0076] The fourth structure of the one-way water supply valve 5 is a spherical structure 54, which includes a valve body 541, a valve ball 542, and a limit cover 543. The valve body 541 is provided with a water injection port and the water port 13. The water injection port is connected to the circulating water chamber 12, and the water port 13 is connected to the clean water chamber 11. The valve ball 542 is located between the water port 13 and the water injection port. The valve ball 542 is located between the water port 13 and the water injection port, and closes the water port 13 when the pressure of the circulating water chamber 12 and the clean water chamber 11 is balanced; when the water pressure in the circulating water chamber 12 drops, a pressure difference is generated between the circulating water chamber 12 and the clean water chamber 11, and the valve column is lifted by the high-pressure water of the clean water chamber 11, opening the water port 13, and the water in the clean water chamber 11 enters the circulating water chamber 12 through the water port 13 and the water injection port. The one-way water supply valve 5 is set as a spherical structure 54, which has a long service life and low cost.

[0077] The filter element 3 is a folded filter cotton. The filter element 3 adopts the filter cotton, which has the advantages of low cost, long service life and easy cleaning.

[0078] In all embodiments, the arrangement of the clean water chamber 11 and the circulating water chamber 12 is as follows: Figures 1 to 11 In addition to the two rectangular structures shown in FIG. Fig.12 As shown, two ring structures are formed.

[0079] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments.
