Description

Technical Field

[0001] The invention relates to the technical field of pet supplies, and in particular to a multifunctional pet drinking fountain. Background Art

[0002] The function of a pet drinking fountain is generally to simulate flowing water to make pets drink more water. When pets are drinking water, the hair on their bodies and the food residues adhering to their mouths are likely to fall into the drinking trough, which will cause the water quality in the drinking trough to be polluted, and then easily breed bacteria, which will have an adverse effect on the health of the pets. In addition, since pets such as cats and dogs use their tongues to drink water, repeated licking of the water surface by the tongue will also cause water pollution, and form a layer of oil film on the water surface of the drinking trough. After a few days, a layer of mucous membrane will also form on the inner wall of the drinking trough. Therefore, even if there is no food residue falling into the drinking trough, the water quality in the drinking trough will also be polluted.

[0046] See also Figure 1a-Figure 13As shown, the present invention provides a multifunctional pet drinking fountain, which includes a water tank 1, a cover plate 2, a reduction motor 3, a water bowl 4, a shell cover 5, a driving mechanism 100, a brush 7, a water pump 8 and a filter element 9. The water tank 1 can be formed by injection molding, and the water tank 1 is used to store water for pets to drink. The cover plate 2 covers the top of the water tank 1, and a downwardly concave reflux groove 201 is provided on the cover plate 2, and the bottom of the reflux groove 201 is connected to the water tank 1. The reduction motor 3 is fixedly connected to the cover plate 2, and the water bowl 4 is connected to the reduction motor 3, and the reduction motor 3 can drive the water bowl 4 to rotate. The shell cover 5 is installed above the cover plate 2, and the driving mechanism 100 is connected to the shell cover 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 driving mechanism 100 can drive the brush 7 to move between the first position and the second position, and the brush 7 rubs the inner wall of the water bowl 4 when moving between the first position and the second position. 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 reflux groove 201. The filter element 9 is arranged in the reflux groove 201. The water flowing into the reflux groove 201 is filtered by the filter element 9 and then flows into the water tank 1.

[0047] The first position of the brush 7 can be seen in Figure 4 shown. Figure 4 The brush 7 in the middle can move to the Figure 1b The location shown, Figure 1b The position of the middle brush 7 is near the second position. When the brush 7 is in the second position, the brush 7 is located above the bottom center of the water bowl 4.

[0048] The working principle of the multifunctional pet drinking fountain provided by the present invention is:

[0049] The water in the water tank 1 is pumped into the water bowl 4 by the water pump 8, so that the water bowl 4 can be continuously supplied with clean water. When the water in the water bowl 4 is full, the water will overflow into the reflux groove 201, and then flow back into the water tank 1 after being filtered by the filter element 9. Such a water circulation loop can continuously renew the water in the water bowl 4, so that the water in the water bowl 4 remains clean, and can also filter the water to prevent the water in the water tank 1 from being polluted. In the process of daily use, pet hair that falls into the water bowl 4 will float on the water surface under the action of water surface tension. These pet hairs will flow into the reflux groove 201 along with the water overflowing from the water bowl 4 in a short time and be filtered out by the filter element 9.

[0050] When the water bowl 4 needs to be cleaned, the water bowl 4 can be driven to rotate by the reduction motor 3, and at the same time, the driving mechanism 100 drives the brush 7 to slowly reciprocate between the first position and the second position. During this process, the brush 7 will fully clean the inner wall of the water bowl 4, and the dirt brushed off from the inner wall of the water bowl 4 will flow into the reflux groove 201 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 reproduction of bacteria, and at the same time, it can also prevent the brush 7 from being contaminated in the water bowl 4. The brush 7 is detachably connected to the driving mechanism 100. After using it for a period of time, the pet keeper can remove the brush 7 separately for cleaning or replacement.

[0051] Compared with the pet owner cleaning the water bowl 4 by himself, the multifunctional pet drinking fountain provided by the present invention realizes automatic cleaning of the water bowl 4. During the cleaning process of the water bowl 4, the pet owner does not need to touch the water bowl 4 and the water, which can avoid the pet owner's hands from getting dirty and save the pet owner's time in cleaning the water bowl 4. Therefore, the multifunctional pet drinking fountain brings great convenience to the pet owner, is conducive to improving the pet owner's pet-raising experience, and allows the pet owner to have more time and energy to devote to entertainment or learning.

[0052] See also Figure 5 As shown, the driving mechanism 100 is mainly composed of a guide rail 10, a rack 11, a stepper motor 12 and a gear 13. The stepper motor 12 here can also be replaced by a servo motor. The shape of the guide rail 10 is roughly arc-shaped. The detailed structure of the guide rail 10 can be seen in Figure 7 The guide rail 10 is provided with ear plates 1006 near both ends thereof, and the ear plates 1006 on the guide rail 10 are fixedly connected to the housing 5 by bolts. The guide rail 10 is also provided with an arc groove 1004 for accommodating the rack 11. The rack 11 is arc-shaped and is arranged in the arc groove 1004. The size of the rack 11 is adapted to the size of the arc groove 1004. The rack 11 can slide in the arc groove 1004. The rack 11 is provided with teeth 1101. 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 portion 1007 for mounting the stepping motor 12, and the stepping motor 12 is fixedly connected to 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 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 the present invention, at least part of the inner wall of the water bowl 4 is a spherical surface 402, the center of the circle corresponding to the arc 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. Fig. 9 As shown, a plurality of drainage holes 4 distributed in a circular array are provided at the bottom of the water bowl 4, and the inner wall of the water bowl 4 located outside the area surrounded by the drainage holes 4 is the aforementioned spherical surface 402. By making the center of the circle corresponding to the arc groove 1004 coincide with the center of the spherical surface 402 and 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 the 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 better cleaning effect.

[0054] See also Figure 6 As shown, the brush 7 is mainly composed of a brush body 701, a brush handle 702 and bristles 703. The brush body 701 and the brush handle 702 are integrally formed, the brush handle 702 is plug-in connected to the rack 11, and the bristles 703 are embedded in the surface of the brush body 701. The brush body 701 and the brush handle 702 can be made of rubber material throughout, so that the brush 7 can be adaptively deformed along with the inner wall of the water bowl 4 when moving in the water bowl 4, thereby ensuring that the bristles 703 on the brush 7 can be more in contact with the inner wall of the water bowl 4, thereby achieving a better cleaning effect.

[0055] In the present 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 is parallel to the second arc plate 1002. The connecting plate 1003 is located between the first arc plate 1001 and the second arc plate 1002 and is connected to the first arc plate 1001 and the second arc plate 1002 at the same time. The first arc plate 1001, the second arc plate 1002 and the connecting plate 1003 jointly define an arc groove 1004. The rack 11 is located between the first arc plate 1001 and the second arc plate 1002. An arc-shaped guide groove 1005 is provided on at least one of the first arc plate 1001 and the second arc plate 1002. The center of the circle corresponding to the guide groove 1005 coincides with the center of the sphere 402. The rack 11 is provided with a guide block 1102 inserted into the guide groove 1005. Figure 7 and Figure 8 As shown, the first arc plate 1001 and the second arc plate 1002 are both provided with guide grooves 1005, and two cylindrical guide blocks 1102 are respectively provided on both sides of the rack 11, and the diameter of the guide blocks 1102 is slightly smaller than the diameter of the guide groove 1005, so as to ensure that the rack 11 can accurately slide along the extension direction of the guide groove 1005. The teeth 1101 on the rack 11 are arranged on the inner side of the rack 11, and the inner edges of the first arc plate 1001 and the second arc plate 1002 are both connected to the connecting plate 1003, and the connecting plate 1003 is provided with a hole for the gear 13 to pass through.

[0056] In the present invention, the multifunctional pet drinking fountain further includes a controller 14 and a power module 15 fixedly connected to the housing 5, the reduction motor 3, the water pump 8, and the stepper motor 12 are all electrically connected to the controller 14, and the power module 15 is used to supply power to the reduction motor 3, the water pump 8, the stepper motor 12, and the controller 14. In a specific implementation, the aforementioned power module 15 can be a rechargeable battery, and the controller 14 can be a single-chip microcomputer.

[0057] The present invention can realize automatic control of the reduction motor 3, the water pump 8, and the 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 a built-in program into the controller 14 to control the reduction motor 3 and the stepper motor 12 to work regularly, the reduction motor 3 and the stepper motor 12 are started at the same time every certain period of time (for example, half an hour) to clean the water bowl 4. In this way, the multifunctional pet drinking fountain can be highly automated, which is more convenient for pet keepers to use.

[0058] like Figure 1a As shown, three control buttons 22 with "power", "clean" and "brush out" respectively marked can also be set on the shell cover 5. When the "power" button 22 is pressed, the water pump 8 is energized, and the water pump 8 supplies water to the water bowl 4. When the pet keeper thinks that the water bowl 4 needs to be cleaned, the "clean" button 22 can be pressed, and the controller 14 controls the reduction motor 3 and the stepper motor 12 to start at the same time to achieve the cleaning of the water bowl 4. When the pet keeper thinks that the brush 7 needs to be cleaned or replaced, the "brush out" button 22 can be pressed, and the controller 14 controls the stepper motor 12 to start, and the stepper motor 12 drives the brush 7 to extend from the shell cover 5 and stay at a position between the first position and the second position. At this time, the brush 7 has not extended into the deepest part of the water bowl 4, and then the brush 7 can be removed for cleaning or replacement.

[0059] In the present invention, the multifunctional pet drinking fountain further comprises a water outlet 16 connected to the shell cover 5, and the shell cover 5 is provided with a special-shaped hole 501, see Figure 1a As shown, the shape of the special-shaped hole 501 is an inverted T-shape, the width of the lower end of the special-shaped hole 501 matches the width of the water outlet 16, and the width of the upper end of the special-shaped hole 501 is slightly larger than the width of the brush 7. Fig.11 , Fig.11a and Fig.11bAs shown, the water outlet 16 includes a bottom plate 1601, a cover 1602 and a connecting pipe 1603. One end of the bottom plate 1601 passes through the special-shaped hole 501 and extends to the top of the water bowl 4. A partial edge of the bottom plate 1601 is provided with a roughly U-shaped enclosure 1604. The cover 1602 is located above the bottom plate 1601 and is connected to the enclosure 1604. The connecting pipe 1603 is connected to the cover 1602. The water outlet 16 is provided with a water injection hole 1605 that passes through the connecting pipe 1603 and the bottom plate 1601. The water outlet end of the water pump 8 is connected to the connecting pipe 1603 through a hose 24, and the brush 7 can pass through the special-shaped hole 501. The shape of the bottom plate 1601 after being connected to the surrounding plate 1604 is similar to a dustpan. The water flowing in from the connecting pipe 1603 can flow out from the front end of the bottom plate 1601. The cover 1602 is mainly used to install the connecting pipe 1603. The size of the cover 1602 is much smaller than that of the bottom plate 1601. During cleaning the water bowl 4, when the brush 7 returns to the first position, the brush 7 is located directly above the bottom plate 1601. Therefore, the water dripping from the brush 7 can drip onto the bottom plate 1601 and re-enter the water bowl 4 with the water flow, thereby preventing the water dripping from the brush 7 from making the multifunctional pet drinking fountain dirty.

[0060] See also Figure 4 and Figure 4b As shown, in order to ensure that the water flowing out of the water outlet 16 is in the water bowl 4 instead of falling on the outside of the water bowl 4, the front end of the water outlet 16 needs to extend to the top of the water bowl 4. It is worth noting that since the brush 7 and the rack 11 need to move just above the water outlet 16 and the moving track is close to the inner wall of the water bowl 4, the water outlet 16 cannot extend too much above the water bowl 4, and the height of the water outlet 16 cannot be much higher than the edge of the water bowl 4; under the aforementioned conditions, if the water outlet 16 provided in the present invention is fixedly connected to the shell cover 5, the difficulty of disassembling or installing the water bowl 4 will be increased.

[0061] In order to reduce the adverse effect of the portion of the water outlet 16 extending above the water bowl 4 on the disassembly and assembly operation of the water bowl 4, the present invention further provides the following technical solutions:

[0062] See also Figure 4b and Fig.11a As shown, the multifunctional pet drinking fountain also includes a support member 17 fixedly connected to the shell cover 5, and a slide groove 1704 is provided on the support member 17, and the slide groove 1704 extends from one end of the support member 17 toward the water bowl 4, and the water outlet 16 also includes a slider 1607 and a limit block 1608, the slider 1607 is located in the slide groove 1704 and is fixedly connected to the bottom plate 1601, the limit block 1608 is connected to the slider 1607, at least a part of the support member 17 is located between the limit block 1608 and the bottom plate 1601, and the shape of the limit block 1608 and the slider 1607 after being connected is roughly an inverted T shape.

[0063] See also Fig.12 As shown, the support member 17 is mainly composed of two mutually perpendicular flat plates 1701, one of which is parallel to the cover plate 2, and the aforementioned slide groove 1704 is arranged on the flat plate 1701 parallel to the cover plate 2. After the slider 1607 is installed in the slide groove 1704, the slider 1607 and the limit block 1608 will limit the water spout 16 to move only along the extension direction of the slide groove 1704. When the water bowl 4 needs to be disassembled or installed, the water spout 16 can be pushed into the shell 5 by hand, so that the front end of the water spout 16 leaves the top of the water bowl 4, so that the water bowl 4 can be disassembled and installed more conveniently.

[0064] In a further improved solution, the multifunctional pet drinking fountain further includes a tension spring 18, the water outlet 16 further includes a pulling column 1606 located below the bottom plate 1601, the upper end of the pulling column 1606 is fixedly connected to the bottom 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 pulling column 1606. Fig.12 As shown, the support member 17 also includes two ribs 1702 and a pin shaft 1703. The two ribs 1702 are parallel to each other. The aforementioned ribs 1702 are perpendicular to the two flat plates 1701 at the same time. The two ends of the pin shaft 1703 are fixedly connected to the two ribs 1702 respectively, and one end of the tension spring 18 is hooked on the pin shaft 1703. In this technical solution, the rib plate 1702 is provided to improve the structural strength of the support member 17. Under normal conditions, the tension spring 18 pulls the pulling column 1606 on the water spout 16, so that the front end of the water spout 16 extends to the top of the water bowl 4 and remains in this position; when the water spout 16 is pushed, the water spout 16 moves toward the inside of the shell cover 5, and the front end of the water spout 16 leaves 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 thrust applied to the water spout 16 is removed, and under the elastic force of the tension spring 18, the front end of the water spout 16 will return to the top of the water bowl 4. Therefore, this technical solution can realize the automatic return of the water spout 16, further improving the convenience of use.

[0065] In the present invention, the bottom center of the water bowl 4 is protruded upward 405, the lowest point in the water bowl 4 is provided with a drainage hole 4, and multiple drainage holes 4 are distributed around the bottom center of the water bowl 4 at intervals; the multifunctional pet drinking fountain also includes a water receiving tray 19, a sink 202 is provided on the cover plate 2, the water receiving tray 19 is embedded in the sink 202, the water receiving 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 drainage hole 4, the annular groove 1902 is connected to the reflux groove 201 through a sewage pipe 20, and the connection between the sewage pipe 20 and the water receiving tray 19 and the cover plate 2 is sealed, the reduction motor 3 is located in the sink 202 and below the water receiving tray 19, and the reduction motor 3 has a connecting member 21 on the rotating shaft, the connecting member 21 is located in the through hole 1901 and the upper end is detachably connected to the bottom of the water bowl 4.

[0066] It is worth noting that the flow rate of the water pump 8 in the present invention is greater than the sum of the flow rates of all the drainage holes 4 to ensure that water can overflow from the water bowl 4, and 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 discharged into the return groove 201 to prevent sewage from overflowing from the annular groove 1902. When there is no pet drinking water, the flow rate of the water pump 8, the flow rate of all drainage holes 4, the overflow of the water bowl 4, and the flow rate of the sewage pipe 20 satisfy the following relationship: the flow rate of the water pump 8 = the overflow of the water bowl 4 + the flow rate of all drainage holes 4 = the overflow of the water bowl 4 + the flow rate of the sewage pipe 20.

[0067] See also Fig. 9 , Figure 9a and Figure 9b As shown, the lower end of the water bowl 4 is provided with a mounting ring 404, and the mounting ring 404 can be connected to the connecting member 21 in a plug-in manner, or the mounting ring 404 and the connecting member 21 can be connected in a threaded manner. In the present invention, by providing a structure with an upward protrusion 405 at the bottom center of the water bowl 4, the dirt such as pet food that sinks to the bottom of the bowl can be moved toward the drain hole 4 under the combined action of water flow and gravity and discharged from the drain hole 4, so that the dirt can be effectively prevented from being deposited at the bottom of the water bowl 4, thereby maintaining the water quality in the water bowl 4. Since the brush body 701 of the brush 7 in the present invention is made of rubber material, 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 deform adaptively with the protrusion 405 structure at the bottom center of the water bowl 4.

[0068] In a preferred embodiment, a circular water stop ring 403 is provided at the lower end of the water bowl 4, and the water stop ring 403 is coaxially arranged with the annular groove 1902. The water stop ring 403 is located in 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 in the annular groove 1902, and 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. Fig.10As shown, the water receiving tray 19 has a column 1903 located in the annular groove 1902 and the through hole 1901, and the sealing ring 6 is sleeved on the column 1903 of the water receiving tray 19. After the multifunctional pet drinking fountain is assembled, the top of the column 1903 is higher than the lower end of the water stop ring 403. The water stop ring 403 and the sealing ring 6 can effectively prevent water from flowing into the bottom of the water receiving tray 19, thereby preventing the motor from being damaged by water. In addition, the edge of the water receiving tray 19 can be sealed with the cover plate 2 to prevent water from seeping into the sink 202 from the gap between the water receiving tray 19 and the cover plate 2.

[0069] like Figure 1a As shown, in the present invention, the reflux groove 201 is arranged at the front end of the cover plate 2, the shell cover 5 is installed at the rear end of the cover plate 2, and the water bowl 4 is located between the reflux groove 201 and the shell cover 5. In order to prevent the water from spilling on the ground when the pet drinks (or when the pet touches the multifunctional pet drinking fountain), a circle of water retaining edge 203 is arranged at the edge of the cover plate 2. In order to ensure that the water spilled on the cover plate 2 can smoothly flow into the reflux groove 201, after the multifunctional pet drinking fountain is assembled, the upper surface of the cover plate 2 forms an angle of about 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 Figure 1a , with the end of the cover plate 2 provided with the reflux groove 201 as the front end of the cover plate 2, and the end of the cover plate 2 provided with the shell cover 5 as the rear end of the front cover plate 2. In order to ensure that the water overflowing from the water bowl 4 can smoothly flow into the reflux groove 201, after the multifunctional pet drinking fountain is assembled, the water bowl 4 is in an inclined posture, and the height of the front end of the water bowl 4 (i.e., the end close to the reflux groove 201) is lower than the height of the rear end of the water bowl 4 (i.e., the end away from the reflux groove 201), so that the water will overflow from the front end of the water bowl 4 and directly flow into the reflux groove 201. For the convenience of assembly, the plane where the bowl edge of the water bowl 4 is located is parallel to the upper surface of the cover plate 2, and the shaft of the reduction motor 3 is perpendicular to the upper surface of the cover plate 2.

[0070] See also Figure 4 As shown, a filter screen 23 is placed above the filter element 9 in the reflux groove 201 . Floating objects such as pet hair flowing out of the water bowl 4 will be filtered by the filter screen 23 . Pet owners can easily take out the filter screen 23 and clean it, which will help to extend the service life of the filter element 9 .

[0071] The multifunctional pet drinking fountain provided by the present invention has three functions of water changing, water filtering and self-cleaning, and is very convenient to use. In particular, its self-cleaning function can effectively remove dirt such as mucous membrane attached to the inner wall of the water bowl 4, and pet owners no longer need to scrub the pet's water bowl 4 by themselves, which can save pet owners a lot of time and energy; moreover, the multifunctional pet drinking fountain has the advantage of stable and reliable structure, and its stable and reliable structure is conducive to reducing the failure rate during daily use; at the same time, the multifunctional pet drinking fountain also has good sealing performance, which is conducive to improving its waterproof level and avoiding leakage incidents during use.
