Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, specifically to a multifunctional pet water dispenser. Background Technology

[0002] Pet water fountains are generally designed to encourage pets to drink more water by simulating flowing water. However, during drinking, pet hair and food residue from their mouths can easily fall into the water trough, contaminating the water and promoting bacterial growth, which can negatively impact a pet's health. Furthermore, since cats and dogs drink using their tongues, repeated licking of the water surface also contributes to contamination, forming an oily film on the surface and, after several days, a sticky film on the inner wall of the trough. Therefore, even without food residue falling into the trough, the water can still become contaminated. This necessitates frequent cleaning of the water trough to maintain cleanliness, adding extra work for pet owners and potentially affecting their mood. Summary of the Invention

[0045] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0046] See Figures 1a-13As shown, this invention provides a multifunctional pet water dispenser, comprising a water tank 1, a cover 2, a geared motor 3, a water bowl 4, a housing 5, a drive mechanism 100, a brush 7, a water pump 8, and a filter element 9. The water tank 1 can be injection molded and is used to store water for pets. The cover 2 covers the water tank 1 and has a downwardly recessed return groove 201, the bottom of which communicates with the water tank 1. The geared motor 3 is fixedly connected to the cover 2, and the water bowl 4 is connected to the geared motor 3, which drives the water bowl 4 to rotate. The housing 5 is installed above the cover 2, and the drive mechanism 100 is connected to the housing 5. The brush 7 has a first position located outside the water bowl 4 and a second position located inside the water bowl 4. The drive mechanism 100 drives the brush 7 to move between the first and second positions, rubbing the inner wall of the water bowl 4 as it moves between them. The water pump 8 is connected to the cover plate 2 and is used to transport the water in the water tank 1 to the water bowl 4. The water overflowing from the water bowl 4 flows into the return channel 201. The filter element 9 is installed in the return channel 201. The water flowing into the return channel 201 is filtered by the filter element 9 and then flows into the water tank 1.

[0047] The first position where brush 7 is located can be seen in [reference]. Figure 4 As shown. Figure 4 The brush 7 in the middle can move to after moving a certain distance. Figure 1b The location shown Figure 1b The middle brush 7 is located near the second position. When brush 7 is in the second position, it is positioned above the center of the bottom of the water bowl 4.

[0048] The working principle of the multifunctional pet water dispenser provided by this invention is as follows:

[0049] Water is pumped from water tank 1 into water bowl 4 by water pump 8, ensuring a continuous supply of clean water to water bowl 4. When water bowl 4 is full, it overflows into return tank 201, and then flows back into water tank 1 after being filtered by filter element 9. This water circulation loop continuously refreshes the water in water bowl 4, keeping it clean and filtering it to prevent contamination of the water in water tank 1. During daily use, pet hair that falls into water bowl 4 will float on the surface due to water surface tension. This pet hair will flow into return tank 201 with the overflowing water in water bowl 4 and be filtered out by filter element 9 in a short time.

[0050] When cleaning the water bowl 4 is required, the geared motor 3 drives the water bowl 4 to rotate. Simultaneously, the drive mechanism 100 drives the brush 7 to slowly reciprocate between the first and second positions. During this process, the brush 7 thoroughly cleans the inner wall of the water bowl 4. The dirt brushed off the inner wall of the water bowl 4 flows with the water into the return channel 201 and is absorbed and filtered by the filter element 9. After cleaning the water bowl 4, the drive mechanism 100 drives the brush 7 back to the first position. This means that when cleaning the water bowl 4 is not required, the brush 7 is always located on the outside of the water bowl 4. This keeps the brush 7 dry, inhibiting bacterial growth and preventing contamination within the water bowl 4. The brush 7 and the drive mechanism 100 are detachably connected. After a period of use, pet owners can remove the brush 7 separately for cleaning or replacement.

[0051] Compared to pet owners cleaning the water bowl 4 themselves, the multifunctional pet water dispenser provided by this invention enables automatic cleaning of the water bowl 4. During the cleaning process, the pet owner does not need to come into contact with the water bowl 4 or the water, which can prevent the pet owner's hands from getting dirty and can also save the pet owner's time in cleaning the water bowl 4. Therefore, this multifunctional pet water dispenser brings great convenience to pet owners, helps to improve the pet owner's pet-raising experience, and allows the pet owner to devote more time and energy to entertainment or learning.

[0052] See Figure 5 As shown, the drive mechanism 100 mainly consists of a guide rail 10, a rack 11, a stepper motor 12, and a gear 13. The stepper motor 12 can also be replaced by a servo motor. The guide rail 10 is roughly arc-shaped; for detailed structure information, please refer to [link to relevant documentation]. Figure 7 Near its two ends, the guide rail 10 has ear plates 1006, which are fixedly connected to the housing 5 by bolts. The guide rail 10 also has an arc-shaped groove 1004 for accommodating the rack 11. The rack 11 is arc-shaped and located within the arc-shaped groove 1004. The size of the rack 11 is adapted to the size of the arc-shaped groove 1004, allowing the rack 11 to slide within it. The rack 11 has teeth 1101, and one end of the rack 11 is detachably connected to the brush 7. See again. Figure 7 As shown, the guide rail 10 is also provided with a mounting part 1007 for mounting the stepper motor 12, and the stepper motor 12 is fixedly connected to the mounting part 1007 on the guide rail 10. The gear 13 is fixed on the rotating shaft of the stepper motor 12 and meshes with the teeth 1101 on the rack 11. When the stepper motor 12 is started, the gear 13 drives the rack 11 to slide in the arc groove 1004, thereby enabling the brush 7 to 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. The brush body 701 and brush handle 702 can be made entirely of rubber, which allows the brush 7 to adapt to the deformation of the inner wall of the water bowl 4 when it moves inside the water bowl 4, thereby ensuring that the bristles 703 on the brush 7 can have more contact with the inner wall of the water bowl 4, thus achieving a better cleaning effect.

[0055] In this invention, the guide rail 10 includes a first arc plate 1001, a second arc plate 1002, and a connecting plate 1003. The first arc plate 1001 and the second arc plate 1002 are parallel. The connecting plate 1003 is located between the first arc plate 1001 and the second arc plate 1002 and is connected to both the first arc plate 1001 and the second arc plate 1002. The first arc plate 1001, the second arc plate 1002, and the connecting plate 1003 together define an arc-shaped groove 1004. A rack 11 is located between the first arc plate 1001 and the second arc plate 1002. At least one of the first arc plate 1001 and the second arc plate 1002 is provided with an arc-shaped guide groove 1005. The center of the guide groove 1005 coincides with the center of the sphere 402. The rack 11 is provided with a guide block 1102 that is inserted into the guide groove 1005. See also Figure 7 and Figure 8 As shown, both the first arc plate 1001 and the second arc plate 1002 are provided with guide grooves 1005. Two cylindrical guide blocks 1102 are provided on each side of the rack 11. The diameter of the guide blocks 1102 is slightly smaller than the diameter of the guide groove 1005, thereby ensuring that the rack 11 can slide accurately along the extension direction of the guide groove 1005. The teeth 1101 on the rack 11 are provided on the inner side of the rack 11. The inner edges of the first arc plate 1001 and the second arc plate 1002 are connected to the connecting plate 1003. The connecting plate 1003 has holes for the gear 13 to pass through.

[0056] In this invention, the multifunctional pet water dispenser also includes a controller 14 and a power module 15 fixedly connected to the housing 5. The geared motor 3, water pump 8, and stepper motor 12 are all electrically connected to the controller 14. The power module 15 is used to supply power to the geared motor 3, water pump 8, stepper motor 12, and controller 14. In a specific implementation, the aforementioned power module 15 can be a rechargeable battery, and the controller 14 can be a microcontroller.

[0057] This invention can automatically control the geared motor 3, water pump 8, and stepper motor 12 through the controller 14. When the power is turned on, the water pump 8 supplies water to the water bowl 4. By loading the built-in program into the controller 14, the geared motor 3 and stepper motor 12 are controlled to work at regular intervals, so that the geared motor 3 and stepper motor 12 start simultaneously at regular intervals (e.g., half an hour) to clean the water bowl 4. In this way, the multi-functional pet water drinker can be highly automated, making it more convenient for pet owners to use.

[0058] like Figure 1a As shown, three control buttons 22 labeled "Power," "Cleaning," and "Brush Out" can also be provided on the housing 5. When the "Power" button 22 is pressed, the water pump 8 is powered on and supplies water to the water bowl 4. When the pet owner thinks the water bowl 4 needs to be cleaned, the "Cleaning" button 22 can be pressed, and the controller 14 will control the geared motor 3 and the stepper motor 12 to start simultaneously to clean the water bowl 4. When the pet owner thinks the brush 7 needs to be cleaned or replaced, the "Brush Out" button 22 can be pressed, and the controller 14 will control the stepper motor 12 to start. The stepper motor 12 drives the brush 7 to extend from inside the housing 5 and stop at a position between the first and second positions. At this time, the brush 7 has not reached the deepest part of the water bowl 4, and then the brush 7 can be removed for cleaning or replacement.

[0059] In this invention, the multifunctional pet water dispenser also includes a water outlet 16 connected to the housing 5. The housing 5 has an irregularly shaped hole 501. (See attached image) Figure 1a As shown, the irregularly shaped hole 501 is an inverted T-shape. The width of the lower end of the irregularly shaped hole 501 matches the width of the water outlet 16, while the width of the upper end of the irregularly shaped hole 501 is slightly larger than the width of the brush 7. See [reference needed] Figure 11 , Figure 11a and Figure 11bAs shown, the water outlet 16 includes a base plate 1601, a cover 1602, and a connecting pipe 1603. One end of the base plate 1601 passes through the irregular hole 501 and extends to the top of the water bowl 4. Part of the edge of the base plate 1601 is provided with a roughly U-shaped surrounding plate 1604. The cover 1602 is located above the base plate 1601 and is connected to the surrounding plate 1604. The connecting pipe 1603 is connected to the cover 1602. The water outlet 16 is provided with a water inlet 1605 that passes through the connecting pipe 1603 and the base plate 1601. The water outlet end of the water pump 8 is connected to the connecting pipe 1603 through a flexible hose 24. The brush 7 can pass through the irregular hole 501. The shape of the base plate 1601 after being connected to the side plate 1604 is similar to a winnowing basket. Water flowing in from the connecting pipe 1603 can flow out from the front end of the base plate 1601. The cover 1602 is mainly used to install the connecting pipe 1603. The size of the cover 1602 is much smaller than the size of the base 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 base plate 1601. Therefore, the water dripping from the brush 7 can drip onto the base plate 1601 and re-enter the water bowl 4 with the water flow. This can prevent the water dripping from the brush 7 from making the multi-functional pet water drinker dirty.

[0060] See Figure 4 and Figure 4b As shown, in order to ensure that the water flowing from the spout 16 is inside the water bowl 4 and does not fall outside the water bowl 4, the front end of the spout 16 needs to extend directly above the water bowl 4. It is worth noting that since the brush 7 and the rack 11 need to move directly above the spout 16 and their movement paths are close to the inner wall of the water bowl 4, the spout 16 cannot extend too far above the water bowl 4, and the height of the spout 16 cannot be much higher than the rim of the water bowl 4. Under the aforementioned conditions, if the spout 16 provided in this invention is fixedly connected to the cover 5, it will increase the difficulty of disassembling or installing the water bowl 4.

[0061] To reduce the adverse effects of the portion of the spout 16 extending above the water bowl 4 on the disassembly and assembly of the water bowl 4, the present invention also provides the following technical solution:

[0062] See Figure 4b and Figure 11a As shown, the multi-functional pet water dispenser also includes a support member 17 fixedly connected to the shell 5. The support member 17 is provided with a groove 1704, which extends from one end of the support member 17 toward the water bowl 4. The water outlet 16 also includes a slider 1607 and a limiting block 1608. The slider 1607 is located in the groove 1704 and fixedly connected to the base plate 1601. The limiting block 1608 is connected to the slider 1607. At least a part of the support member 17 is located between the limiting block 1608 and the base plate 1601. The shape of the limiting block 1608 and the slider 1607 after connection is roughly an inverted T-shape.

[0063] See Figure 12 As shown, the support member 17 mainly consists of two mutually perpendicular flat plates 1701, one of which is parallel to the cover plate 2. The aforementioned sliding groove 1704 is provided on the flat plate 1701 parallel to the cover plate 2. After the slider 1607 is installed in the sliding groove 1704, the slider 1607 and the limiting block 1608 will limit the water outlet 16 to move only along the extension direction of the sliding groove 1704. When it is necessary to disassemble or install the water bowl 4, the water outlet 16 can be pushed into the housing 5 by hand, so that the front end of the water outlet 16 is away from the top of the water bowl 4, thus making it easier to disassemble and install the water bowl 4.

[0064] In a further improvement, the multi-functional pet water fountain also includes a tension spring 18, and the spout 16 includes a pull post 1606 located below the base plate 1601. The upper end of the pull post 1606 is fixedly connected to the base plate 1601, one end of the tension spring 18 is connected to the support member 17, and the other end of the tension spring 18 is connected to the pull post 1606. See also Figure 12 As shown, the support member 17 also includes two stiffening plates 1702 and a pin 1703. The two stiffening plates 1702 are parallel to each other and are perpendicular to the two flat plates 1701. The two ends of the pin 1703 are fixedly connected to the two stiffening plates 1702 respectively, and one end of the tension spring 18 is hooked on the pin 1703. In this technical solution, the rib plate 1702 can improve the structural strength of the support member 17. Under normal conditions, the tension spring 18 pulls the tension column 1606 on the spout 16, so that the front end of the spout 16 extends above the water bowl 4 and remains in this position. When the spout 16 is pushed, the spout 16 moves towards the inside of the housing 5, and the front end of the spout 16 moves away from the top of the water bowl 4. The tension spring 18 is stretched, and then the water bowl 4 can be installed or removed. After the water bowl 4 is installed or removed, the pushing force applied to the spout 16 is removed. Under the elastic force of the tension spring 18, the front end of the spout 16 will return to the top of the water bowl 4. Therefore, this technical solution can realize the automatic return of the spout 16, further improving the convenience of use.

[0065] In this invention, the bottom center of the water bowl 4 protrudes upward 405, and the lowest point inside the water bowl 4 is provided with a drain hole 4. Multiple drain holes 4 are distributed around the bottom center of the water bowl 4 at intervals. The multi-functional pet water dispenser also includes a water tray 19. The cover plate 2 is provided with a sink 202. The water tray 19 is embedded in the sink 202. The water tray 19 is provided with a through hole 1901 located in the center and an annular groove 1902 surrounding the through hole 1901. The annular groove 1902 is located below the drain hole 4. The annular groove 1902 is connected to the return channel 201 through a sewage pipe 20. The connection between the sewage pipe 20 and the water tray 19 and the cover plate 2 is sealed. The reduction motor 3 is located inside the sink 202 and below the water tray 19. The shaft of the reduction motor 3 has a connector 21. The connector 21 is located inside the through hole 1901 and its upper end is detachably connected to the bottom of the water bowl 4.

[0066] It is worth noting that in this invention, the flow rate of the water pump 8 is greater than the sum of the flow rates of all the drain holes 4 to ensure that water can overflow from the water bowl 4. Furthermore, the inner diameter of the sewage pipe 20 needs to be large enough to allow the water in the annular groove 1902 to be quickly drained into the return groove 201, preventing sewage from overflowing from the annular groove 1902. When no pet is drinking water, the flow rate of the water pump 8, the flow rates of all the drain holes 4, the overflow amount of the water bowl 4, and the flow rate of the sewage pipe 20 satisfy the following relationship: Flow rate of the water pump 8 = Overflow amount of the water bowl 4 + Flow rate of all the drain holes 4 = Overflow amount of the water bowl 4 + Flow rate of the sewage pipe 20.

[0067] See Figure 9 , Figure 9a and Figure 9b As shown, the lower end of the water bowl 4 is provided with an installation ring 404. The installation ring 404 can be connected to the connector 21 by plugging and unplugging, or the installation ring 404 and the connector 21 can be connected by threads. In this invention, by setting an upward protrusion 405 at the center of the bottom of the water bowl 4, the pet food and other dirt that have sunk to the bottom of the bowl can move towards the drain hole 4 and be discharged from the drain hole 4 under the combined action of water flow and gravity. This can effectively prevent dirt from accumulating at the bottom of the water bowl 4, thereby maintaining good water quality in the water bowl 4. Since the brush body 701 of the brush 7 in this invention is made of rubber, when the brush 7 moves to the second position at the bottom of the water bowl 4, the bristles 703 and the brush body 701 on the brush 7 will adaptively deform with the protrusion 405 structure at the center of the bottom of the water bowl 4.

[0068] In a preferred embodiment, the lower end of the water bowl 4 is provided with an annular water-stop ring 403. The water-stop ring 403 is coaxially arranged with the annular groove 1902. The water-stop ring 403 is located within the annular groove 1902 and is close to the bottom center of the water bowl 4 relative to the drain hole 4. A sealing ring 6 coaxial with the water-stop ring 403 is provided within the annular groove 1902. The inner edge of the sealing ring 6 is connected to the water receiving tray 19, and the outer edge of the sealing ring 6 contacts the inner wall of the water-stop ring 403. See also Figure 10As shown, the water tray 19 has a cylindrical portion 1903 located within the annular groove 1902 and the through hole 1901. A sealing ring 6 is fitted onto the cylindrical portion 1903 of the water tray 19. After the multi-functional pet water dispenser is assembled, the top of the cylindrical portion 1903 is higher than the bottom of the water-stop ring 403. The water-stop ring 403 and the sealing ring 6 effectively prevent water from flowing into the lower part of the water tray 19, thus preventing water from entering and damaging the motor. Furthermore, the edge of the water tray 19 can be sealed to the cover plate 2, preventing water from seeping into the settling tank 202 through the gap between the water tray 19 and the cover plate 2.

[0069] like Figure 1a As shown, in this invention, the return channel 201 is located at the front end of the cover plate 2, the housing 5 is installed at the rear end of the cover plate 2, and the water bowl 4 is located between the return channel 201 and the housing 5. To prevent water from spilling onto the ground when the pet drinks (or when the pet touches the multi-functional pet water fountain), a water-blocking edge 203 is provided around the edge of the cover plate 2. To ensure that water spilled on the cover plate 2 can flow smoothly into the return channel 201, after the multi-functional pet water fountain is assembled, the upper surface of the cover plate 2 forms an angle of approximately 2 degrees with the horizontal plane, and the front end of the cover plate 2 is lower than the rear end of the cover plate 2; see also Figure 1a The end of the cover plate 2 with the return channel 201 is the front end of the cover plate 2, and the end of the cover plate 2 with the shell cover 5 is the rear end of the front cover plate 2. To ensure that the water overflowing from the water bowl 4 can flow smoothly into the return channel 201, after the multi-functional pet water drinker is assembled, the water bowl 4 is tilted, and the height of the front end of the water bowl 4 (i.e., the end near the return channel 201) is lower than the height of the rear end of the water bowl 4 (i.e., the end away from the return channel 201). In this way, the water will overflow from the front end of the water bowl 4 and flow directly into the return channel 201. For ease of assembly, the plane of the rim of the water bowl 4 is parallel to the upper surface of the cover plate 2, and the shaft of the geared motor 3 is perpendicular to the upper surface of the cover plate 2.

[0070] See Figure 4 As shown, a filter screen 23 is also placed in the return channel 201 above the filter element 9. Pet hair and other floating objects flowing out of the water bowl 4 will be filtered by the filter screen 23. Pet owners can easily remove the filter screen 23 and clean it, which will help extend the service life of the filter element 9.

[0071] The multifunctional pet water dispenser provided by this invention has three functions: water changing, water filtration, and self-cleaning. It is very convenient to use, especially its self-cleaning function, which can effectively remove the mucus and other dirt attached to the inner wall of the water bowl 4, eliminating the need for pet owners to wash the pet's water bowl 4 themselves, saving pet owners a lot of time and energy. Moreover, this multifunctional pet water dispenser has the advantage of stable and reliable structure, which helps to reduce the failure rate during daily use. At the same time, this multifunctional pet water dispenser also has good sealing performance, which helps to improve its waterproof rating and avoid leakage incidents during use.
