When the trough 40 is assembled with the water tank 10, the bottom groove 41 is inserted into the water tank 10, the bottom surface of the flange 42 abuts against the upper end surface of the water tank 10, and the flange 42 and the water tank 10 are connected by gluing or bolting, so that the trough 40 is fixed above the water tank 10.

Specifically, the trough 40 of the present embodiment is a runway-type structure, one end of the trough 40 in the length direction is provided with a water return port 421, the other end of the trough 40 in the length direction is provided with an opening for the water spraying platform to pass through, and the opening continues to extend toward the water storage cavity 11 to form an installation end 44. The bottom groove 41 of the drinking water groove 40 has an arc-shaped surface recessed toward the water storage chamber 11, and the water return port 421 is provided above the arc-shaped surface, specifically, the water return port 421 of the present embodiment is provided between the bottom groove 41 and the flange 42. Therefore, when the water pumping device 20 pumps water to the drinking trough 40 through the water spraying platform 50, the bottom trough 41 with the arc-shaped surface which is concavely arranged towards the water storage cavity has a water storage function and is used for pets to drink. When the water pump 20 continuously pumps water and the water level in the drinking trough 40 reaches the height of the water return port 421, the water in the drinking trough 40 flows back to the water tank 10 through the water return port 421, so that the overflow caused by excessive water in the drinking trough 40 is prevented from influencing the surrounding environment. Meanwhile, because the bottom groove 41 has a water storage function, even if the water pumping device 20 stops working, the water in the drinking water groove 40 can still provide a certain amount of water for the pet to drink. Furthermore, large particle impurities in the drinking trough 40 can be retained in the arc structure of the trough bottom 41 and cannot flow back to the water storage cavity 11 through the water return port 421, so that backflow or water supply blockage is prevented.

Referring to fig. 3, 15 and 16, the mounting end 44 of the drinking trough 40 of the present embodiment includes a first pipe section 441, a second pipe section 442 and a first radial section 443 arranged in the axial direction from top to bottom. Wherein the first pipe section 441 has an inner diameter dimension greater than that of the second pipe section 442, and the second pipe section 442 has an inner diameter dimension greater than that of the intermediate opening of the first radial section 443, thereby facilitating the insertion of the water jet table 50 into the second pipe section 442 and into abutment with the end surface of the first radial section 443. Further, the middle opening dimension of the first radial section 443 is larger than the diameter dimension of the connecting portion 62 of the protection cover 60, so that the connecting portion 62 of the protection cover 60 can be conveniently inserted into the mounting end 44 to supply water to the water spraying station 50, and the axial position of the protection cover 60 is positioned by the first radial section 443, so that the protection cover 60 is prevented from being overturned or greatly displaced radially.

Further, a sealing slope 444 is provided between the first pipe segment 441 and the second pipe segment 442 in the present embodiment, when the bottom of the water spraying platform 50 is inserted into the second pipe segment 442, the sealing ring at the bottom of the water spraying platform 50 abuts against the sealing slope 444, so that the sealing ring effectively seals between the water spraying platform 50 and the mounting end 44 under the mutual pressing of the water spraying platform 50 and the sealing slope 444, and prevents water from flowing back into the water tank 10 from the gap between the water spraying platform 50 and the mounting end 44, thereby ensuring that the water storage amount in the drinking trough 40 is kept in a large state. Meanwhile, compared with the front surface contact extrusion sealing ring, the inclined surface is matched with the sealing ring, so that the silica gel piece is easy to deform to form sealing, and the rotary damping between the water spraying platform 0 and the water trough 40 is further reduced, so that the rotating angle of the water spraying platform 50 is convenient to adjust.

As shown in fig. 3, 18 and 19, the pet drinking fountain 1 of the present embodiment further includes a filter core box 70, the filter core box 70 is connected to the bottom of the drinking trough 40 and is disposed opposite to the water return port 421, and water returning to the water storage chamber 11 through the water return port 421 is filtered by the filter core box 70 to remove small particles and impurities therein, thereby ensuring cleanness of water quality for circulating water supply.

The cartridge case 70 of the present embodiment includes a case body 71 and a second cartridge 72 disposed in the case body 71, and specifically, the case body 71 of the present embodiment includes a support plate 711 and a side plate 712 disposed around a surface of the support plate 711, and the side plate 712 and the support plate 711 enclose a groove structure with a large opening, so as to facilitate cleaning of an inner surface of the side plate 712 and an inner surface of the support plate 711. The second filter element 712 is detachably disposed in a recess structure defined by the side plate 712 and the support plate 711 to define a large opening, thereby facilitating installation and removal of the second filter element 712. Wherein, two side walls arranged along the length direction of the side plate 712 are respectively arranged near two inner walls of the water tank 10, and two side walls arranged along the length direction of the side plate 712 are respectively provided with a drain port 713, and a diversion slope 714 inclined downwards towards the inner wall of the water tank 10 is arranged at the drain port 713. The water returning through the water returning port 421 returns to the water storage chamber 11 through the drain ports 713 at both sides after being filtered by the second filter element 72. Because the diversion slopes 714 at the drainage ports 713 are inclined downwards towards the inner wall of the water tank 10, water flowing out of the drainage ports 713 at two sides can flow downwards to the water storage cavity 11 through the inner walls at two sides of the water tank 10, and the water flowing out of the drainage ports 713 at two sides is prevented from directly impacting on the water surface of the water storage cavity 11, so that noise generated during water backflow is effectively reduced, and the experience of a user during use is improved.

Referring to fig. 17 and 18, a baffle 43 is disposed at the bottom of the drinking trough 40 of the present embodiment, and the baffle 43 faces the water storage chamber 11 and is disposed around the outside of the filter cartridge 70. Wherein, be equipped with two connection knot positions 432 of relative setting on the baffle 43, be equipped with two connection knots 715 of relative setting on the curb plate 712 of filter core box 70, two connection knots 715 correspond the plug-in respectively to two connection knot positions 432 on, thereby articulate filter core box 70 to the baffle 43 of trough 40 bottom on, and the curb plate 712 of filter core box 70 is connected with the laminating of the internal face of baffle 43, thereby prevent that the water of backward flow from not passing through the bottom gap outflow between curb plate 712 and baffle 43 promptly after the filtration of second filter core 72.

Further, the top of the baffle 43 of the present embodiment is provided with an overflow hole 431. The height of the overflow hole 431 is less than that of the water return port 421, and the height of the overflow hole 431 is greater than that of the drain port 713. When the second filter element 72 is blocked and the water flowing back cannot flow back to the water storage cavity through the drain port 713, the water in the filter element box 70 can drop into the water storage cavity 11 through the overflow hole 431 at the top of the baffle 43, so that the backflow process is completed, and the situation that the water in the drinking trough 40 overflows the drinking trough 40 and damages the surrounding environment due to the fact that the filter element box 70 is blocked and cannot flow back is effectively prevented. Furthermore, the overflow hole 431 of the present embodiment is disposed at the bottom of the end of the drinking trough 40 far from the water spraying platform 50, and an auxiliary overflow hole is further disposed at the top of the other end of the drinking trough 40 near the water spraying platform 50, and the height of the auxiliary overflow hole is higher than the water return port 421, so that when the water output of the water spraying platform 50 is too large, or the second filter element 71 is blocked, or the pet water dispenser 1 is inclined, the water in the drinking trough 40 can flow back to the water storage cavity 11 through the auxiliary overflow hole, thereby effectively preventing the water in the drinking trough 40 from overflowing to the outside of the pet water dispenser.
