[0047] The first position of brush 7 can be seen from Figure 4 as shown. Figure 4 The brush 7 in Figure 1b moves a distance and can move to Figure 1b position shown, The position of brush 7 in

[0048] is close to the second position.When brush 7 is located at the second position, brush 7 is located above the center of the bottom of water bowl 4.

[0049] The working principle of the water dispenser provided by the utility model is that:

[0050] When the water bowl 4 needs to be cleaned, the water bowl 4 can be driven to rotate by the speed reducer motor 3, and at the same time, the brush 7 is driven to reciprocate slowly between the first position and the second position by the driving mechanism 100, and in the process, the brush 7 can clean the inner wall of the water bowl 4 comprehensively, and the dirt brushed off from the inner wall of the water bowl 4 can flow into the backflow groove 201 along with the water flow and be adsorbed and filtered by the filter element 9. After the water bowl 4 is cleaned, the driving mechanism 100 drives the brush 7 to return to the first position, that is, when the water bowl 4 does not need to be cleaned, the brush 7 is located outside the water bowl 4, so that the brush 7 can be kept dry, thereby inhibiting the breeding of bacteria, and meanwhile, the brush 7 can be prevented from being contaminated in the water bowl 4. The brush 7 is detachably connected with the driving mechanism 100, and after being used for a period of time, the pet feeder can separately take out the brush 7 for cleaning or replacement.

[0051] Compared with the cleaning of the water bowl 4 by the pet feeder, the multifunctional pet water dispenser provided by the utility model realizes the automatic cleaning of the water bowl 4, and in the process of cleaning the water bowl 4, the pet feeder does not need to contact the water bowl 4 and water, the hands of the pet feeder can be prevented from being dirty, and the time of the pet feeder for cleaning the water bowl 4 can be saved; therefore, the multifunctional pet water dispenser brings great convenience to the pet feeder, is favorable for improving the pet feeding experience of the pet feeder, and enables the pet feeder to have more time and energy to put into entertainment or learning.

[0052] Referring to Figure 5 , the driving mechanism 100 mainly comprises a guide rail 10, a rack 11, a stepping motor 12 and a gear 13, and the stepping motor 12 herein can also be replaced by a servo motor. The guide rail 10 is approximately arc-shaped, and the detailed structure of the guide rail 10 can be seen from Figure 7 , the guide rail 10 is provided with an ear plate 1006 near both ends of the guide rail 10, the ear plate 1006 on the guide rail 10 is fixedly connected with the shell 5 through bolts, and the guide rail 10 is further provided with an arc-shaped groove 1004 for accommodating the rack 11.

Referring again to Figure 7 , the guide rail 10 is further provided with a mounting portion 1007 for mounting the stepping motor 12, and the stepping motor 12 is fixedly connected with the mounting portion 1007 on the guide rail 10. The gear 13 is fixed on the rotating shaft of the stepping motor 12 and meshes with the teeth 1101 on the rack 11. When the stepping motor 12 is started, the rack 11 is driven to slide in the arc-shaped groove 1004 by the gear 13, and then the brush 7 can move between the first position and the second position.

[0053] In this invention, the inner wall of the water bowl 4 is at least partially a spherical surface 402, the center of the arc-shaped groove 1004 coincides with the center of the spherical surface 402, and the outer diameter of the rack 11 is smaller than the diameter of the spherical surface 402. See also... Figure 9 As shown, a plurality of drain holes 4 are arranged in a circular array at the bottom of the water bowl 4. The inner wall of the water bowl 4 outside the area enclosed by the drain holes 4 is the aforementioned spherical surface 402. By aligning the center of the arc groove 1004 with the center of the spherical surface 402 and making the outer diameter of the rack 11 smaller than the diameter of the spherical surface 402, it is ensured that the rack 11 can carry the brush 7 into the water bowl 4, thereby achieving cleaning of the water bowl 4. Moreover, when the brush 7 enters the water bowl 4, the movement trajectory of the brush 7 can match the inner wall of the water bowl 4, ensuring a good cleaning effect.

[0054] See Figure 6 As shown, the brush 7 mainly consists of a brush body 701, a brush handle 702, and bristles 703. The brush body 701 and brush handle 702 are integrally formed, and the brush handle 702 is plugged into the rack 11. The bristles 703 are embedded in the surface of the brush body 701.

[0057] The multifunctional pet water fountain can realize automatic control of the speed reducer 3, the water pump 8 and the stepping motor 12 through the controller 14, the water pump 8 supplies water to the water bowl 4 when the power is turned on, the built-in program is loaded in the controller 14 to control the speed reducer 3 and the stepping motor 12 to work regularly, so that the speed reducer 3 and the stepping motor 12 start to clean the water bowl 4 at intervals (for example, half an hour), thereby realizing high automation of the multifunctional pet water fountain and being more convenient for pet breeders to use.

[0058] As shown in Figure 1a , three control buttons 22 respectively marked with “power”, “cleaning” and “brush” can be arranged on the shell cover 5. When the “power” button 22 is pressed, the water pump 8 is powered on, and the water pump 8 supplies water to the water bowl 4. When the pet breeder thinks that the water bowl 4 needs to be cleaned, the “cleaning” button 22 can be pressed, and the controller 14 controls the speed reducer 3 and the stepping motor 12 to start simultaneously to realize cleaning of the water bowl 4. When the pet breeder thinks that the brush 7 needs to be cleaned or replaced, the “brush” button 22 can be pressed, and the controller 14 controls the stepping motor 12 to start, and the stepping motor 12 drives the brush 7 to extend out of the shell cover 5 and stop at a position between the first position and the second position, at this time, the brush 7 does not extend to the deepest part of the water bowl 4, and then the brush 7 can be disassembled for cleaning or replacement.

[0059] The multifunctional pet water fountain further comprises a water outlet nozzle 16 connected with the shell cover 5, the shell cover 5 is provided with a special-shaped hole 501, as shown in Figure 1a , the special-shaped hole 501 is in the shape of an inverted T, the width of the lower end of the special-shaped hole 501 is matched with the width of the water outlet nozzle 16, and the width of the upper end of the special-shaped hole 501 is slightly larger than the width of the brush 7.

The shape of the bottom plate 1601 after being connected with the surrounding plate 1604 is similar to that of a dustpan, the water flowing from the connecting pipe 1603 can flow out from the front end of the bottom plate 1601, the cover 1602 is mainly used for mounting the connecting pipe 1603, the size of the cover 1602 is far smaller than that of the bottom plate 1601, during the cleaning of the water bowl 4, when the brush 7 returns to the first position, the brush 7 is located directly above the bottom plate 1601, thus the water dripping from the brush 7 can drip on the bottom plate 1601 and re-enter the water bowl 4 along with the water flow, so that the water dripping from the brush 7 can prevent the multifunctional pet water dispenser from being dirty.

[0060] As shown in the drawings, Figure 4 and Figure 4b In order to ensure that the water flowing out of the water outlet nozzle 16 is in the water bowl 4 instead of falling outside the water bowl 4, the front end of the water outlet nozzle 16 needs to extend above the water bowl 4, and it is worth noting that, since the brush 7 and the rack 11 need to move above the water outlet nozzle 16 and the moving track is close to the inner wall of the water bowl 4, the water outlet nozzle 16 cannot extend too much above the water bowl 4, and the height of the water outlet nozzle 16 cannot be too high than the bowl rim of the water bowl 4; under the foregoing conditions, if the water outlet nozzle 16 provided in the utility model is fixedly connected with the shell cover 5, the dismounting or mounting difficulty of the water bowl 4 will be increased.

[0061] In order to reduce the adverse effect of the part of the water outlet nozzle 16 extending above the water bowl 4 on the dismounting or mounting operation of the water bowl 4, the utility model further provides the following technical scheme:

[0062] As shown in the drawings, Figure 4b and Figure 11a The multifunctional pet water dispenser further comprises a supporting piece 17 fixedly connected with the shell cover 5, the supporting piece 17 is provided with a sliding groove 1704 extending from one end of the supporting piece 17 towards the water bowl 4, the water outlet nozzle 16 further comprises a sliding block 1607 and a limiting block 1608, the sliding block 1607 is located in the sliding groove 1704 and fixedly connected with the bottom plate 1601, the limiting block 1608 is connected with the sliding block 1607, at least part of the supporting piece 17 is located between the limiting block 1608 and the bottom plate 1601, and the shape of the limiting block 1608 after being connected with the sliding block 1607 is substantially inverted T-shaped.

[0063] Referring to Figure 12 As shown in the figure, the support 17 is mainly composed of two mutually perpendicular flat plates 1701, one of which is parallel to the cover plate 2, and the aforementioned sliding groove 1704 is arranged on the flat plate 1701 parallel to the cover plate 2. After the sliding block 1607 is installed in the sliding groove 1704, the sliding block 1607 and the limiting block 1608 will define that the water outlet nozzle 16 can only move along the extension direction of the sliding groove 1704.
