Description

Technical Field

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

[0002] As people's living standards improve, more and more people are choosing to keep pets at home, which requires the use of pet water fountains. Currently, many pet water fountains are available on the market, and some even have built-in filters that filtration the circulating water.

[0003] For example, Chinese invention patent application CN202111109122.0 provides an anti-overflow structure, a drinking component, and a pet water fountain, but the pet water fountain provided has the following defects during use:

[0004] 1. After a period of use, pet hair or food residue can easily clog the return water filter, which requires pet owners to clean the return water filter regularly. Moreover, the process of cleaning the return water filter is very tedious and seriously affects the user experience of pet owners.

[0005] 2. Pet hair or food scraps will deteriorate if they accumulate in the return water filter section for a long time. This will cause the water entering the water tank to be secondary polluted by the deteriorated pet hair or food scraps, which will increase the filtration burden on the fine filter and shorten its lifespan, thus resulting in higher operating costs for users.

[0006] 3. Unfiltered water flows directly back into the water tank, resulting in a higher organic content in the water. This allows bacteria to multiply rapidly in the tank, further increasing the filtration burden on the fine filter. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a pet water dispenser, aiming to at least partially solve one of the technical problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A pet water fountain includes a water tank, a drinking dish, a water supply assembly, a roller, a water receiving component, and a filter. The water supply assembly draws water from the water tank into the drinking dish. The roller is rotatable around its own axis. One end of the roller has a cylindrical cavity, and the outer circumference of the roller has multiple through holes communicating with the cylindrical cavity. A filter screen is attached to the wall of the cylindrical cavity. The water receiving component is at least partially located inside the cylindrical cavity, and the upper end of the water receiving component has a water receiving trough located inside the cylindrical cavity. Water in the water receiving trough flows into the filter and, after being filtered by the filter, flows back to the water tank.

[0010] In some embodiments, the pet water fountain further includes an air tube and an air supply assembly. The air tube is located inside the roller and has a downward-facing air outlet. The air supply assembly is connected to the air tube and supplies air into the air tube.

[0011] In some embodiments, the pet water fountain further includes a drive mechanism for driving the roller to rotate about the roller's axis.

[0012] In some embodiments, the pet water fountain also includes a housing located above the water reservoir, with a drawer extending below the roller.

[0013] In some embodiments, the drinking tray includes a water-holding section at the front end and a sloping section at the rear end. Water in the water tank is pumped by the water supply assembly to the top of the sloping section and flows into the water-holding section along the sloping section. Water in the drinking tray overflows from the end of the water-holding section away from the sloping section.

[0014] In some embodiments, an ultraviolet lamp is provided at the bottom of the enclosure.

[0015] In some embodiments, the housing includes a bottom box covering a water tank and a lid covering the bottom box. The roller, filter, and air supply assembly are all located within the space formed by the bottom box and the lid. The drinking tray is placed on the lid, which has a reflux hole located above the roller.

[0016] In some embodiments, the water supply assembly includes a water pump, an inlet pipe, an outlet pipe, and an outlet elbow. The water pump is fixedly connected to the base box. The lower end of the inlet pipe extends into the water storage tank, and the upper end of the inlet pipe is connected to the inlet end of the water pump. The lower end of the outlet pipe is connected to the outlet end of the water pump, and the upper end of the outlet pipe passes through the box cover. One end of the outlet elbow is rotatably connected to the upper end of the outlet pipe, and the other end of the outlet elbow extends to the top of the slope.

[0017] In some embodiments, the drive mechanism includes a rotating shaft, a bearing housing, a motor, and a transmission assembly. The rotating shaft is connected to the base box via the bearing housing and is coaxial with the roller. One end of the rotating shaft is fixedly connected to the roller. The motor is fixedly connected to the base box. The motor is connected to the rotating shaft via the transmission assembly and drives the rotating shaft to rotate.

[0018] In some embodiments, the transmission assembly includes a driving pulley connected to a motor, a driven pulley disposed on a rotating shaft, and a transmission belt connecting the driving pulley and the driven pulley.

[0019] Compared with existing technologies, the pet water dispenser provided by this utility model uses a high-speed airflow from the air tube to blow animal hair and food residue out of the through-hole during use. When the through-hole rotates back from the bottom to the top of the roller, it is almost free of animal hair or food residue. Therefore, animal hair or food residue can only remain in the through-hole temporarily, preventing them from accumulating for a long time and avoiding fermentation and spoilage. This reduces the burden on the filter, extends its service life, and lowers the operating costs for pet owners. Moreover, this pet water dispenser features automatic roller cleaning, requiring only periodic removal of blown-off animal hair or food residue, eliminating the need for frequent cleaning by pet owners and making it more convenient to use.

[0045] See Figures 1 to 15As shown, this invention provides a pet water drinker capable of purifying water. The pet water drinker includes a water tank 1, a housing 100 positioned above the water tank 1, a drinking tray 4 on the housing 100, and a water supply assembly 200 for drawing water from the water tank 1 into the drinking tray 4. The pet water drinker also includes a roller 5, a drive mechanism, a water receiving component 6, a filter 7, an air pipe 8, and an air supply assembly 9. The axis of the roller 5 is parallel to the horizontal plane, and the roller 5 has a cylindrical cavity 501. One end of the roller 5 is open, and the other end is closed. Multiple through holes 502 communicating with the cylindrical cavity 501 are provided on the outer circumference of the roller 5. A filter screen 10 is attached to the wall of the cylindrical cavity 501. The drive mechanism is used to drive the roller 5 to rotate around its axis. The water receiving component 6 has a water receiving trough 601. The water receiving component 6 extends from the open end of the roller 5 into the cylindrical cavity 501, and the connecting post 603 of the water receiving component 6 extends from the open end and is fixedly connected to the housing 100. Specifically, the upper end of the water receiving component 6 is provided with a water receiving trough 601 located in the cylindrical cavity 501; the filter 7 is fixedly connected to the housing 100, and the water receiving trough 601 is connected to the filter 7 through a pipe. The water in the water receiving trough 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 component 6. The air pipe 8 is provided with an air outlet 801 facing downward; the air supply component 9 is connected to the housing 100 and is used to supply air to the air pipe 8; wherein, the drinking tray 4 is located above the roller 5, and the water overflowing from the drinking tray 4 flows into the water receiving trough 601 through the through hole 502.

[0046] Before using the pet water fountain, the housing 100 and water dish 4 can be removed from the top of the water tank 1, and then water can be added to the water tank 1. In some embodiments, a water inlet hole can also be provided on the outer wall of the water tank 1. 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 water fountain, the water supply component 200 continuously pumps water from the water tank 1 to the drinking dish 4. Simultaneously, the drive mechanism drives the roller 5 to rotate at a low speed. When the drinking dish 4 is full, it naturally overflows. Animal hair, food scraps, and other debris in the drinking dish 4 flow onto the outer surface of the roller 5 with the overflowing water, thus ensuring the continuous replenishment of the water in the drinking dish 4 and maintaining its cleanliness. The water flowing onto the outer surface of the roller 5, under the influence of gravity, flows through the through-hole 502 into the water receiving tank 601. During this process... Animal hair and food scraps are filtered out by the filter screen 10 and temporarily stored in the through hole 502. When the through hole 502 carrying animal hair and food scraps moves to the bottom of the roller 5 as the roller 5 rotates, the high-speed airflow blown out of the air tube 8 blows the animal hair and food scraps out of the through hole 502. The water in the water tank 601 flows into the water storage tank 1 after being filtered by the filter 7. Since the water in the water tank 601 has already undergone primary filtration by the filter screen 10, the filter 7 can be guaranteed to have a long service life, thereby reducing the operating costs for pet owners.

[0048] It is worth noting that during use, the high-speed airflow from the air tube 8 blows animal hair and food residue out of the through hole 502. When the through hole 502 rotates back from the bottom to the top of the roller 5, it is almost free of animal hair or food residue. Therefore, animal hair or food residue can only remain in the through hole 502 for a short time, which can prevent the accumulation of animal hair or food residue in the through hole 502 for a long time and avoid fermentation and deterioration. This reduces the burden on the filter 7, gives the filter 7 a longer service life, and reduces the operating costs for pet owners.

[0049] This pet water fountain features automatic cleaning of the roller 5. Simply remove any loose pet hair or food scraps periodically, eliminating the need for pet owners to clean the fountain frequently, making it more convenient to use.

[0050] Since the aforementioned filter 10 is only used to filter larger particles such as animal hair or food scraps, while ensuring smooth water flow, the mesh size of the filter 10 can be selected from 95 to 180. The inventors' experiments have shown that a mesh size of around 145 achieves better results. The filter 7 in this invention is mainly used to filter out small pollutants such as organic matter in the water. Therefore, the water returning to the outlet tank contains very little organic matter, effectively preventing the proliferation of bacteria in the water storage tank.

[0051] See Figure 2As shown, to facilitate regular cleaning of blown-off pet hair, food scraps, and other debris, the housing 100 is equipped with a drawer 11 extending below the roller 5. Pet hair and food scraps blown out through the through-hole 502 will fall into the drawer 11. When it is necessary to clean up the blown-off pet hair and food scraps, the user simply pulls out the drawer 11 and emptys the debris, making it more convenient to use.

[0052] In some embodiments, to further improve the water exchange efficiency within the drinking tray 4, the drinking tray 4 includes a water-holding section 401 at the front end and a sloping section 402 at the rear end. Water in the water storage tank 1 is pumped by the water supply assembly 200 to the top of the sloping section 402 and flows along the sloping section 402 into the water-holding section 401. Water in the drinking tray 4 overflows from the end of the water-holding section 401 away from the sloping section 402. See also Figure 14 As shown, Figure 14 The dotted line in the diagram represents the highest water level 24 in the drinking tray 4. The portion below the water level 24 is the water-holding section 401, and the portion above the water level 24 is the slope section 402. In specific implementations, the overall shape of the drinking tray 4 can be appropriately modified. To ensure that food residue at the bottom of the water-holding section 401 can be quickly discharged, the maximum water depth of the water-holding section 401 should not be too large, and should be controlled within 30mm. Furthermore, the maximum water depth of the water-holding section 401 is directly proportional to the height of the slope section 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 above the slope section 402. The water flowing out has significant potential energy, resulting in a high flow velocity in the water-holding section 401. This effectively flushes away animal hair floating on the surface and food residue settled at the bottom of the drinking tray 4.

[0053] In some embodiments, to prevent bacteria from multiplying in the water storage tank 1, an ultraviolet lamp 12 can be installed at the bottom of the tank 100 to irradiate the water stored in the water storage tank 1, thereby killing the bacteria in the water.

[0054] See Figure 1 , Figure 2 and Figure 13As shown, the housing 100 includes a base box 2 covering the water tank 1 and a cover 3 covering the base box 2. The roller 5, filter 7, and air supply assembly 9 are all located within the space formed by the base box 2 and the cover 3. The drinking tray 4 is placed on the cover 3, which has a return hole 301 located above the roller 5. By installing the roller 5, filter 7, and air supply assembly 9 within the space formed by the base box 2 and the cover 3, accidental contact by people or pets can be avoided, thereby reducing the risk of equipment damage and making the product's appearance more concise and aesthetically pleasing. To prevent the drinking tray 4 from shaking, a rectangular insertion hole 302 located near the return hole 301 can be provided on the cover 3. At the same time, a plug 403 matching the aforementioned insertion hole 302 can be provided at the bottom of the drinking tray 4. During use, the plug 403 is inserted into the insertion hole 302.

[0055] See Figure 9 As shown, the water receiving component 6 is injection molded from plastic. The lower end of the water receiving component 6 has three mounting plates 602 for installing the air pipe 8. The bottom of the mounting plate 602 has round holes adapted to the air pipe 8. The air pipe 8 is inserted into the round holes on the mounting plate 602 to fix it in place. The right end of the water receiving component 6 has two connecting posts 603, and the base box 2 has a vertical plate 201. Both connecting posts 603 are fixedly connected to the vertical plate 201 by fasteners. The air supply component 9 in this invention can be an air pump, which is connected to the air pipe 8 via a pipe.

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

[0057] See Figure 1 and Figure 12 As shown, the pet water fountain also includes a funnel 13 located within the return hole 301. The lower end of the funnel 13 has an elongated drain outlet 1301. The length of the drain outlet 1301 is aligned with the extension direction of the axis of the roller 5. The length and width of the drain outlet 1301 are smaller than the length and width of the through hole 502, respectively. When in use, water flowing from the drinking tray 4 flows into the aforementioned funnel 13. The funnel 13 ensures that all water flows into the through hole 502, further preventing water overflowing from the drinking tray 4 from flowing down the surface of the roller 5 to the bottom of the roller 5.

[0058] In this invention, the water supply assembly 200 includes a water pump 14, an inlet pipe 15, an outlet pipe 16, and an outlet elbow 17. The water pump 14 is fixedly connected to the base box 2. The lower end of the inlet pipe 15 extends into the water storage tank 1, and the upper end of the inlet pipe 15 is connected to the inlet end of the water pump 14. The lower end of the outlet pipe 16 is connected to the outlet end of the water pump 14, and the upper end of the outlet pipe 16 passes through the box cover 3. One end of the outlet elbow 17 is rotatably connected to the upper end of the outlet pipe 16, and the other end of the outlet elbow 17 extends above the slope surface 402. The outlet elbow 17 can rotate around the outlet pipe 16, and can be rotated at a certain angle to prevent the outlet elbow 17 from affecting the installation or removal of the drinking tray 4.

[0059] See Figure 2 and Figure 6 As shown, the drive mechanism includes a rotating shaft 18, a bearing housing 19, a motor 20, and a transmission assembly. The rotating shaft 18 is connected to the base box 2 via the bearing housing 19 and is coaxial with the roller 5. One end of the rotating shaft 18 is fixedly connected to the roller 5. The motor 20 is fixedly connected to the base box 2 via an L-shaped bending piece. The motor 20 is connected to the rotating shaft 18 via the transmission assembly and drives the rotating shaft 18 to rotate. The transmission assembly includes a driving pulley 21 connected to the motor 20, a driven pulley 22 disposed on the rotating shaft 18, and a transmission belt connecting the driving pulley 21 and the driven pulley 22. The transmission belt is not shown in the figure. In some embodiments, the transmission assembly may also be a sprocket set or a gear set.

[0060] The water pump 14, motor 20, and ultraviolet lamp 12 in this invention can be powered by indoor power or by a built-in rechargeable battery 23. See also Figure 2 As shown, when powered by a rechargeable battery 23, the battery 23 is installed inside the housing 100. The water pump 14, motor 20, air pump and ultraviolet lamp 12 are all electrically connected to the battery 23. A charging interface for charging the battery 23 can be provided on the housing 100. Control switches for controlling the water pump 14, motor 20 and ultraviolet lamp 12 can also be provided on the housing 100.
