DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0027] like Figure 1-8As shown, a pet drinking fountain comprises a body 1, a water supply structure and a water pump 6; the water supply structure comprises an upper cover 2, a filter element 3, a water tray 4 and a water supply assembly 5; a accommodating cavity is provided inside the body 1; the water tray 4 is provided with a water holding cavity; the upper cover 2 is provided with a water purification hole 21, and the water purification hole 21 is communicated with the accommodating cavity; the upper cover 2 is arranged at the upper end of the accommodating cavity; the filter element 3 is arranged above the water purification hole 21; the water tray 4 is arranged on the upper cover 2; the input end of the water pump 6 is communicated with the accommodating cavity, and the output end of the water pump 6 is communicated with the water holding cavity through the water supply assembly 5.

[0028] Specifically, in the actual application of the pet drinking water machine, it is necessary to first add drinking water into the body 1. The drinking water is added from the top of the upper cover 2. The drinking water will be filtered through the filter element 3, and then the filtered clean water will flow into the accommodating cavity through the clean water hole 21, so that the filtered clean water is stored in the accommodating cavity; when the pet needs to drink water, the water pump 6 is started to transport the clean water in the accommodating cavity to the water holding cavity of the water tray 4, and the pet can drink the filtered clean water from the water holding cavity. When the water in the water holding cavity is full or the pet leaks water when drinking, the water will also flow back to the upper surface of the upper cover 2 through the water tray 4, and then enter the accommodating cavity after being filtered through the filter element 3 again, which is beneficial to the circulation of water, thereby achieving the purpose of saving and not wasting.

[0029] Furthermore, the filter element 3 includes a support plate 31, a cover plate 32 and a filter material 33; the support plate 31 is provided with a filter element cavity; the support plate 31 is provided with a clean water outlet 311 and a first clean water channel opening 312, and the cover plate 32 is provided with a filtered water inlet 321 and a second clean water channel opening 322; the first clean water channel opening 312 and the second clean water channel opening 322 are butt-jointedly arranged; the support plate 31 and the cover plate 32 are covered to form a filter element cavity, and the filter material 33 is arranged in the filter element cavity; the clean water outlet 311 and the filtered water inlet 321 are both connected to the filter element cavity.

[0030] Specifically, the first water purification channel opening 312 and the second water purification channel opening 322 are butted together to form a water purification channel that runs through the filter element 3. When the filter element 3 is installed in the water dispenser, the water of the water dispenser can be transported through the water purification channel through pipes, etc., so that the overall structure is more compact and the volume of the water dispenser is reduced. In specific operation, water enters the filter element cavity from the water filtration inlet 321, and after being filtered by the filter material 33 in the filter element cavity, the water flows out from the water purification outlet 311 and enters the water storage chamber of the pet water dispenser.

[0031] Furthermore, the support plate 31 is provided with a first snap-fit ​​portion 313 , and the cover plate 32 is provided with a first snap-fit ​​portion 323 , and the first snap-fit ​​portion 313 is snap-fitted with the first snap-fit ​​portion 323 .

[0032] Specifically, long-term use of the filter element 3 will cause the filtering performance of the filter material 33 to decrease, and therefore the filter material 33 needs to be replaced. The support plate 31 and the cover plate 32 of the present invention are detachably connected, making the filter element 3 simpler and more convenient to install or disassemble, and facilitating the replacement of the filter material 33, thereby solving the problem that the traditional filter element 3 is difficult to disassemble and replace the filter material 33 due to welding connection, or the entire filter element 3 needs to be replaced, resulting in high costs.

[0033] Furthermore, a first flange 314 is provided at the edge of the first clean water channel opening 312 .

[0034] Specifically, when installing the cover plate 32 , after the cover plate 32 and the support plate 31 are snap-fitted together, the first flange 314 can support the bottom of the cover plate 32 , thereby supporting the cover plate 32 and ensuring the stability and firmness of the structure.

[0035] Furthermore, the first flange 314 is provided with a second locking portion 315 , and the lower end of the cover plate 32 is provided with a second buckle portion 324 , and the second buckle portion 324 is buckled and connected with the second buckle portion 315 .

[0036] Specifically, in this embodiment, a second set of snap-fit ​​structures is provided on the first flange 314 , and the second snap-fit ​​portion 324 is snap-fitted to the second engaging portion 315 , so as to further enhance the stability of the structure and ensure the firmness and stability of the structure.

[0037] Furthermore, the first flange 314 is also provided with a clean water side outlet 316 .

[0038] Specifically, the first flange 314 in this embodiment is provided with the clean water side outlet 316. In addition to being able to flow out through the clean water outlet 311, the water filtered by the filter material 33 can also flow out through the clean water side outlet 316. When the water intake of the filter element 3 is large, the flow rate of the water is increased through the clean water side outlet 316, which helps to improve the working efficiency of the filter element 3.

[0039] Furthermore, a rib 317 is provided at the bottom of the filter element cavity of the support plate 31 , one end of the rib 317 extends to the first water purification channel opening 312 , and the other end of the rib 317 extends to the inner wall of the edge of the support plate 31 .

[0040] Specifically, the rib 317 is provided at the bottom of the filter element cavity of the support plate 31 in this embodiment, and the rib 317 acts as a reinforcing rib, which is beneficial to enhancing the rigidity of the structure and making the support plate 31 more secure and less prone to damage; in addition, the filter material 33 is arranged in the filter element cavity, and the filter material 33 is positioned by the rib 317, which has the effect of limiting the position and fixing the filter material 33, and helps to prevent the filter material 33 from loosening.

[0041] Furthermore, the water filter inlet 321 includes a plurality of strip-shaped slots, and the strip-shaped slots are spirally arranged along the center of the cover plate 32 , and the strip-shaped slots are arranged around the central circumference of the cover plate 32 .

[0042] Specifically, the strip-shaped slot is a spiral slot, and the center of the spiral is the center of the cover plate 32; the strip-shaped slot can not only increase the area of ​​the water inlet, thereby increasing the water intake, but also guide the incoming drinking water so that the drinking water flows according to the shape of the strip-shaped slot, so that the water flow is relatively concentrated, turbulence is prevented when the water enters, and it is beneficial for the passage of the water flow.

[0043] Furthermore, the water tray 4 is also provided with a water supply channel 41; the water supply component 5 is detachably arranged in the water supply channel 41, so that the upper end of the water supply component 5 is connected to the water storage cavity, and the lower end of the water supply component 5 is connected to the purified water output end.

[0044] Specifically, during installation, the water tray 4 is first installed and fixed on the upper cover 2, and then the water supply assembly 5 is installed in the water supply channel 41. When installing the water supply assembly 5, the water supply assembly 5 is limited in the water supply channel 41 to keep the water supply assembly 5 vertical, which is conducive to aligning the water supply assembly 5 with the clean water output end during installation; in addition, the water supply assembly 5 and the water tray 4 are detachably connected, and the water supply assembly 5 can be installed or disassembled separately, which is not only easy to operate, but also convenient to install or disassemble and maintain, and it is easier to align the installation with the clean water output end to ensure a tight connection with the clean water output end, thereby solving the problems of the water tray 4 and the water pipe being an integrated structure in the traditional technology, which is troublesome to install or disassemble, and it is difficult to align with the clean water output end, resulting in unstable water supply.

[0045] Furthermore, the water supply assembly 5 includes a water supply end cover 51, a delivery pipe 52 and a clean water hose 53; the water supply end cover 51 is provided with a water supply cavity, and a water outlet 511 is provided on the side of the water supply end cover 51; the delivery pipe 52 is arranged inside the water supply cavity; the clean water hose 53 is arranged at the input end of the delivery pipe 52; and the output end of the delivery pipe 52 is connected to the water supply cavity.

[0046] Specifically, when assembling the water supply component 5, first install the delivery pipe 52 in the water supply cavity. In this embodiment, the delivery pipe 52 and the water supply end cover 51 are connected in a threaded connection, which is a detachable connection, convenient for installation and later maintenance and disassembly; then install the clean water hose 53 at the bottom end of the delivery pipe 52, that is, the input end of the delivery pipe 52; in specific work, clean pet drinking water is input from the clean water hose 53, then enters the water supply cavity through the delivery pipe 52, then flows out through the water outlet 511, and then flows into the water holding cavity of the water tray 4 for the pet to drink.

[0047] Furthermore, a first sealing rubber ring 54 is provided on the outside of the water supply end cover 51 .

[0048] Specifically, the first sealing rubber ring 54 plays a role of sealing and water isolation, which can prevent the water in the water tray 4 from flowing back into the clean water, and prevent the contaminated water in the water tray 4 from flowing back into the filtered clean water, causing the clean water to be polluted.

[0049] Furthermore, the water supply installation structure also includes a nut 7, the upper cover 2 is provided with a mounting hole, and the bottom end of the water tray 4 is provided with a threaded portion 42; the threaded portion 42 passes through the mounting hole and is connected with the nut 7; the upper cover 2 is arranged between the nut 7 and the water tray 4.

[0050] Specifically, when installing the water tray 4, the water tray 4 is placed above the upper cover 2, the threaded portion 42 is passed through the mounting hole, and then the nut 7 is installed on the threaded portion 42. At this time, the upper cover 2 is located between the nut 7 and the bottom of the water tray 4. By tightening the nut 7, the water tray 4 is fixed at the mounting hole of the upper cover 2.

[0051] Furthermore, an overhead rib 34 is provided at the lower end of the filter element 3 .

[0052] Specifically, after the filter element 3 is installed on the top of the upper cover 2, since the overhead ribs 34 are provided below the filter element 3, a cavity is formed between the filter element 3 and the upper surface of the upper cover 2, so that the water filtered by the filter element 3 can flow out quickly, preventing the upper surface of the upper cover 2 and the lower surface of the filter element 3 from fitting together and causing blockage, which makes it difficult for the filtered water to flow out.

[0053] Furthermore, a fixing flange 35 is provided at the upper end of the filter element 3 .

[0054] Specifically, after the filter element 3 is installed, the water tray 4 is installed above the filter element 3 and connected to the upper cover 2. Since the fixing flange 35 is provided in this embodiment, under the action of the fixing flange 35, the water tray 4 presses down the filter element 3, so that the filter element 3 is clamped by the lower surface of the water tray 4 and the upper surface of the upper cover 2, so that the filter element 3 can be fixed between the water tray 4 and the upper cover 2.

[0055] Furthermore, a second sealing rubber ring 36 is provided on the outside of the filter element 3 .

[0056] Specifically, the second sealing rubber ring 36 is arranged between the filter element 3 and the upper cover 2. When water flows from above the filter element 3, the second sealing rubber ring 36 can play a role of sealing and water isolation, preventing water from passing through the gap between the outside of the filter element 3 and the upper cover 2 without being filtered by the filter element 3, thereby entering the clean water containing chamber, thereby achieving the purpose of ensuring the filtering effect.

[0057] Furthermore, a return flange 43 is provided on the edge of the water tray 4 .

[0058] Specifically, when the water in the water holding cavity of the water tray 4 overflows, the water will remain in the upper cover 2. The water tray 4 in this embodiment is provided with the reflux flange 43. The reflux flange 43 allows a water flow channel to exist between the water tray 4 and the upper cover 2. The water overflowing to the upper cover 2 can flow into the filter element 3 through the water flow channel, and re-enter the clean water holding cavity after being filtered by the filter element 3.

[0059] Furthermore, the upper cover 2 is snap-connected to the body 1 , a third snap-connecting portion 22 is provided at the edge of the upper cover 2 , and the body 1 is provided with a third snap-connecting portion 11 ; the third snap-connecting portion 22 and the third snap-connecting portion 11 are snap-connected in cooperation.

[0060] Specifically, the upper cover 2 is connected to the body 1 by a snap-fit ​​connection, which is simple and convenient to operate and is conducive to improving the installation speed. Due to its detachable feature, it is also more convenient to disassemble, repair or maintain later, and the upper cover 2 can be disassembled more quickly to improve work efficiency.

[0061] Furthermore, a suction cup 61 is provided at the lower end of the water pump 6 , and the water pump 6 is fixed to the bottom of the accommodating cavity through the suction cup 61 .

[0062] Specifically, in this embodiment, a suction cup 61 is provided at the lower end of the water pump 6, and the water pump 6 is fixed by the suction cup 61. The suction cup 61 is sucked onto the inner wall of the body 1, so that the installation and removal of the water pump 6 are relatively convenient and quick.

[0063] Furthermore, the body includes an inner shell and an outer shell, and the inner shell is snap-connected to the outer shell.

[0064] Specifically, a cavity is formed between the inner shell and the outer shell, and the electrical components of the water dispenser, such as circuit boards and wires, are arranged in the cavity. The snap connection between the inner shell and the outer shell facilitates installation and disassembly, making it convenient for installation and later disassembly and maintenance.

[0065] Furthermore, the pet drinking fountain also includes a protective plate 62 ; the protective plate 62 is disposed on the body 1 and around the water pump 6 .

[0066] Specifically, the protective plate 62 is also provided on the outside of the water pump 6. Since the water pump 6 is immersed in water, if the water dispenser shakes under the action of external force, the water pump 6 may shake. Therefore, the protective plate 62 is provided in this embodiment. The protective plate 62 surrounds the water pump 6 to protect the water pump 6, prevent the water pump 6 from shaking, and maintain the stability of the connection of the water pump 6.

[0067] Furthermore, the pet water dispenser further includes a threading hole 12; the threading hole 12 is arranged at the upper part of the accommodating cavity.

[0068] Specifically, a waterproof sealing rubber ring is provided in the threading hole 12, and the wires of the water pump 6 pass through the threading hole 12. Compared with the structure in which the threading hole 12 is set at the bottom, in the present technical solution, under normal circumstances, the threading hole 12 is set at the upper part of the accommodating cavity and is not immersed in water. Therefore, the waterproof requirement of the threading hole 12 can be reduced, and the threading hole 12 can be made larger, so that the end of the wire of the water pump 6 can be provided with a terminal to be plugged into the circuit board, thereby replacing the welding of the traditional structure.

[0069] Furthermore, the pet water dispenser also includes a light sensor 13 .

[0070] Specifically, since most pets are active during the day and rest at night, the light sensor 13 is provided in this embodiment. The light sensor 13 can sense the external brightness to judge day and night, so as to control the water dispenser to start during the day and shut down at night, thereby reducing the working time of the water pump 6 and extending the life of the water pump 6.

[0071] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
