[0045] See also Figures 1 to 15 As shown, the present invention provides a pet drinking fountain capable of purifying water, the pet drinking fountain capable of purifying water comprises a water storage tank 1, a box body 100 arranged above the water storage tank 1, a water tray 4 arranged on the box body 100 and a water supply assembly 200 for pumping water in the water storage tank 1 into the water tray 4; the pet drinking fountain capable of purifying water also comprises a drum 5, a driving mechanism, a water receiving member 6, a filter 7, an air pipe 8 and an air supply assembly 9; the axis of the drum 5 is parallel to the horizontal plane, the drum 5 has a cylindrical cavity 501, one end of the drum 5 is open and the other end is closed; a plurality of through holes 502 communicating with the cylindrical cavity 501 are arranged on the outer circumference of the drum 5, and a filter screen 10 is attached to the wall of the cylindrical cavity 501; the driving mechanism is used to drive the drum 5 to rotate around the axis of the drum 5; the water receiving tank of the water receiving member 6 601 extends from the open end of the drum 5 into the cylindrical cavity 501, and the connecting column 603 of the water receiving piece 6 extends from the open end and is fixedly connected to the box body 100. Specifically, the upper end of the water receiving piece 6 is provided with a water receiving groove 601 located in the cylindrical cavity 501; the filter 7 is fixedly connected to the box body 100, and the water receiving groove 601 is connected to the filter 7 through a pipeline. The water in the water receiving groove 601 flows into the filter 7 and flows into the water storage tank 1 after being filtered by the filter 7; the air pipe 8 is located in the cylindrical cavity 501 and is fixedly connected to the bottom of the water receiving piece 6. The air pipe 8 is provided with an air outlet 801 facing downward; the air supply component 9 is connected to the box body 100 and is used to supply air to the air pipe 8; wherein, the water tray 4 is located above the drum 5, and the water overflowing from the water tray 4 flows into the water receiving groove 601 through the through hole 502.

[0046] Before using the pet drinking fountain capable of purifying water, the box 100 and the water tray 4 can be removed from above the water tank 1, and then water can be poured into the water tank 1. In some embodiments, a water injection hole can also be provided on the outer wall of the water tank 1. In order to facilitate observation of the water level in the water tank 1, the water tank 1 can be made of transparent plastic material, or a transparent observation window can be provided on the outer wall of the water tank 1.

[0047] During the use of the pet drinking fountain capable of purifying water, the water supply component 200 continuously pumps the water in the water storage tank 1 into the water drinking tray 4. At the same time, the driving mechanism drives the drum 5 to rotate at a low speed. When the water in the water drinking tray 4 is full, it will naturally overflow. The animal hair, food residues and other dirt in the water drinking tray 4 will flow to the outer peripheral surface of the drum 5 with the overflowing water. In this way, the water in the water drinking tray 4 can be continuously renewed to ensure the cleanliness of the water in the water drinking tray 4. The water flowing to the outer peripheral surface of the drum 5 flows into the water receiving tank 601 through the through hole 502 under the action of gravity. In this process, The animal hair and food residues in the recycled water are filtered out by the filter 10 and temporarily stored in the through hole 502. When the through hole 502 carrying the animal hair and food residues moves to the bottom of the drum 5 as the drum 5 rotates, the high-speed airflow blown out of the air pipe 8 blows the animal hair and food residues out of the through hole 502; the water in the water receiving tank 601 is filtered by the filter 7 and then flows into the water storage tank 1. Since the water in the water receiving tank 601 has been primarily filtered by the filter 10, the filter 7 can be guaranteed to have a long service life, thereby reducing the use cost of pet owners.

[0048] It is worth noting that during the use of the pet drinking fountain that can purify water, the high-speed airflow blown out from the air pipe 8 blows animal hair and food residues out of the through hole 502. When the through hole 502 rotates from the bottom of the drum 5 to the top of the drum 5 again, the through hole 502 contains almost no animal hair or food residues, so the animal hair or food residues can only remain in the through hole 502 for a short time, which can prevent the animal hair or food residues from accumulating in the through hole 502 for a long time, and avoid the animal hair or food residues from fermenting and deteriorating in the through hole 502, thereby reducing the burden on the filter 7, making the filter 7 have a longer service life, and reducing the use cost of the pet owner.

[0049] The pet drinking fountain capable of purifying water realizes automatic cleaning of the drum 5. It only needs to regularly remove the blown-off animal hair or food residues. The pet owner does not need to clean the drinking fountain frequently, and the use is more convenient.

[0050] Since the aforementioned filter 10 is only used to filter animal hair or food residues and other large-sized dirt, and it is necessary to ensure that water can flow out smoothly, the mesh number of the filter 10 can be selected in the range of 95 to 180. The inventor has found through experiments that a better use effect can be achieved when the mesh number of the filter 10 is about 145. The filter 7 in the present invention is mainly used to filter small pollution sources such as organic matter in water, so the water flowing back to the water outlet contains very little organic matter, which can effectively prevent bacteria from multiplying in large quantities in the water storage tank.

[0051] See also Figure 2As shown, in order to facilitate the user to regularly clean the dirt such as animal hair and food residues blown off, the box body 100 is provided with a drawer 11 extending to the bottom of the drum 5, and the dirt such as animal hair and food residues blown off from the through hole 502 will fall into the drawer 11. When it is necessary to clean the dirt such as animal hair and food residues blown off, the user can pull out the drawer 11 and pour out the dirt in the drawer 11, which is more convenient to use.

[0052] In some embodiments, in order to further improve the water replacement efficiency in the water tray 4, the water tray 4 includes a water holding portion 401 at the front end and a slope portion 402 at the rear end. The water in the water storage tank 1 is pumped to the top of the slope portion 402 by the water supply assembly 200 and flows into the water holding portion 401 along the slope portion 402. The water in the water tray 4 overflows from the end of the water holding portion 401 away from the slope portion 402. Fig.14 As shown, Fig.14 The dotted line in the figure represents the highest water level line 24 in the water tray 4. The part below the water level line 24 of the water tray 4 is the water holding part 401, and the part above the water level line 24 of the water tray 4 is the slope part 402. The overall shape of the water tray 4 can also be appropriately changed during implementation. In order to ensure that the food residues sunk at the bottom of the water holding part 401 can be quickly discharged, the maximum water depth of the water holding part 401 should not be too large. The maximum water depth of the water holding part 401 should be controlled within 30 mm, and the maximum water depth of the water holding part 401 is proportional to the height of the slope part 402 and the flow rate of the water supply component 200. In this embodiment, the water supply component 200 lifts the water in the water storage tank 1 to the top of the slope part 402. The water has a large potential energy after flowing out, so that the water flowing into the water holding part 401 has a large flow rate, so that the animal hair floating on the water surface and the food residues settled on the bottom of the water can be better washed away from the water tray 4.

[0053] In some embodiments, in order to prevent bacteria from multiplying in large numbers in the water storage tank 1, an ultraviolet lamp 12 may be disposed at the bottom of the housing 100, and the ultraviolet lamp 12 may be used to irradiate the water stored in the water storage tank 1, thereby killing the bacteria in the water.

[0054] See also Figure 1 , Figure 2 and Fig.13As shown, the box body 100 includes a bottom box 2 covering the water tank 1 and a box cover 3 covering the bottom box 2. The drum 5, the filter 7 and the air supply assembly 9 are all located in the space formed by the bottom box 2 and the box cover 3. The water tray 4 is placed on the box cover 3. The box cover 3 is provided with a reflux hole 301 located above the drum 5. By installing the drum 5, the filter 7 and the air supply assembly 9 in the space formed by the bottom box 2 and the box cover 3, it is possible to avoid accidental contact by people or pets, thereby reducing the risk of damage to the equipment, and also making the appearance of the product more concise and beautiful. In order to prevent the water tray 4 from shaking, a rectangular plug 302 located near the reflux hole 301 can be provided on the box cover 3, and a plug block 403 matching the aforementioned plug 302 is provided at the bottom of the water tray 4. When in use, the plug block 403 is inserted into the plug 302.

[0055] See also Fig. 9 As shown, the water receiving part 6 is injection molded by plastic material, and the lower end of the water receiving part 6 has three mounting plates 602 for mounting the air pipe 8, and the bottom of the mounting plate 602 is provided with a circular hole adapted to the air pipe 8, and the air pipe 8 is inserted into the circular hole on the mounting plate 602 to achieve the fixation of the air pipe 8; the right end of the water receiving part 6 has two connecting columns 603, and the bottom box 2 has a vertical plate 201, and the two connecting columns 603 are fixedly connected to the vertical plate 201 by fasteners. The air supply component 9 in the present invention can adopt an air pump, and the air pump is connected to the air pipe 8 through a pipeline.

[0056] See also Figure 8 As shown, in order to ensure that the water overflowing from the water tray 4 flows into the through hole 502 better, the through hole 502 is designed to be long and narrow, and the length direction of the through hole 502 is consistent with the extension direction of the axis of the drum 5, and the width of the through hole 502 is 4 to 10 mm. Fig.15 As shown, the water overflowing from the water tray 4 forms a miniature waterfall, and the length L1 of the through hole 502 should be greater than the width L2 of the water waterfall 25 overflowing from the water tray 4 to prevent the water overflowing from the water tray 4 from flowing along the surface of the drum 5 to the bottom of the drum 5.

[0057] See also Figure 1 and Fig.12 As shown, the pet drinking fountain capable of purifying water quality further comprises a funnel 13 located in the reflux hole 301, and a long strip-shaped water outlet 1301 is provided at the lower end of the funnel 13. The length direction of the water outlet 1301 is consistent with the extension direction of the axis of the drum 5, and the length and width of the water outlet 1301 are respectively smaller than the length and width of the through hole 502. When the pet drinking fountain capable of purifying water quality is in use, the water flowing out of the water tray 4 flows into the aforementioned funnel 13, and the provided funnel 13 can ensure that all the water can flow into the through hole 502, thereby further preventing the water overflowing from the water tray 4 from flowing along the surface of the drum 5 to the bottom of the drum 5.

[0058] In the present invention, the water supply assembly 200 includes a water pump 14, a water inlet pipe 15, a water outlet pipe 16 and a water outlet elbow 17.
