Description

Technical Field

[0001] This utility model relates to the field of pet drinking technology, and more specifically, to a pet drinking filter box, drinking stand and water dispenser. Background Technology

[0002] Pet ownership is now common in modern life, and people all hope their pets will grow up healthy. With traditional direct feeding methods, pets are prone to urinary tract diseases or bacterial infections due to unclean water. Therefore, water fountains with purification functions are gradually gaining popularity among consumers. Currently, there are various pet water fountains on the market, but relying solely on simple and crude filtration methods still cannot meet the needs of refined pet feeding.

[0003] A search revealed numerous publicly available patents on pet water purification technology. For example, patent CN213555801U discloses a fine filter cartridge for a pet water fountain, using materials such as water-based filters, ion exchange resins, activated carbon, quartz sand, or mineralized balls. The filter cartridge utilizes a grid pattern on its support to ensure more even distribution of the filter media, maximizing contact with the water and enhancing purification capabilities. However, the filter media cannot be easily replaced, resulting in higher overall costs. Patent CN220642830U discloses a pet water fountain filter cartridge with removable and replaceable filter media, featuring multiple layers including filter cotton, coconut shell activated carbon, ion exchange resin, quartz sand particles, and maifan stone particles. While replaceable, this design is cumbersome and inconvenient for users. Furthermore, the actual purification effects of various filter materials used in the industry vary considerably.

[0005] In view of the shortcomings of existing pet drinking water filtration performance and low ease of use, it is proposed to provide a pet drinking water filter box, drinking stand and water dispenser. The filter box design can effectively ensure drinking water purification performance and is more convenient to use, which helps to improve the user experience.

[0006] 2. Technical Solution

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] This utility model discloses a pet drinking water filter box. The filter box has a filtration space for placing filter media. This filtration space is divided into an upper filtration area and a lower filtration area by a perforated partition. The upper filtration area is an open space at the top, in which the first filter media is laid and can detach from the open space. The lower filtration area has a bottom wall, in which a second filter media is laid in the closed space between the bottom wall and the partition. A drainage channel communicating with the filtration space is also provided on the outer wall of the filter box for water to flow out.

[0009] Furthermore, the first and second filter media are of different types, and the filtration life of the second filter media is longer than that of the first filter media.

[0010] Furthermore, the bottom wall of the filter box seals the bottom of the lower filtration area, and the drainage channel is opened on the outer wall of the filter box. The outer wall and the bottom wall together form the filtration space.

[0011] Furthermore, the top two sides of the upper filtration area are provided with inwardly extending limiting parts to limit the two ends of the first filter material laid below.

[0012] Furthermore, the drainage channel is also equipped with an outlet filter layer, through which the water filtered by the first and second filter media is discharged.

[0013] Furthermore, the drainage channel is opened on the outer wall of the filter box, and multiple sets of inner positioning ribs are provided at intervals along the length of the water outlet filter layer on the inner side of the outer wall, and the water outlet filter layer is clamped between the outer wall and the inner positioning ribs.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example

[0038] Combination Figures 1-6 As shown in this embodiment, a pet drinking water filter box 300 has a filtration space for placing filter media. This filtration space is divided into an upper filtration area and a lower filtration area by a perforated partition 310. The upper filtration area is an open space at the top, where the first filter media is laid and can detach from the open space. The lower filtration area has a bottom wall 302, where the second filter media is laid in the closed space between the bottom wall 302 and the partition 310. A drainage channel 303 communicating with the filtration space is also provided on the outer wall of the filter box 300 for water to flow out. By setting up an interconnected double-layer filtration space, a double-layer filtration effect is formed, effectively improving the filtration efficiency.

[0039] More preferably, the first and second filter media are of different types, and the filtration life of the second filter media is longer than that of the first filter media. Through the above design, a double-layer distribution is adopted, using different materials to achieve multiple filtration, effectively improving the filtration and purification effect. The upper layer is an open space to place the first filter media with a shorter energy efficiency period, which can be easily replaced by the user in a timely manner. The lower layer is a sealed space to place the second filter media with a longer energy efficiency period. In this way, when the first filter media expires, only the first filter media needs to be replaced, instead of replacing the entire filter box 300, which can effectively reduce the replacement frequency of the entire filter box 300 and reduce the operating cost.

[0040] Furthermore, the filter box 300 is equipped with a perforated partition 310, which divides the filtration space of the filter box 300 into an interconnected upper filtration area and a lower filtration area. The first filter media is laid on the partition 310, and the second filter media is laid between the partition 310 and the bottom wall 302. The partition 310 can adopt a grid design, with a perforated center for water flow downwards. The partition 310 serves as both a dividing surface and a supporting surface, providing stable support for the first filter media. Users can simply remove the old filter media and lay the new filter media flat to complete the replacement of the first filter media. The stable filter media also ensures stable filtration performance.

[0041] In practice, the first filter media can be filter cotton 305, and the second filter media can be ceramic balls 309. The grid gaps of the baffle 310 ensure smooth water flow and provide stable support, while the gaps are insufficient for the lower layer of ceramic balls 309 to pass through. Specifically, the filter cotton 305 can be PP filter cotton, effectively filtering hair, etc., while the ceramic balls 309 can be high-silver ceramic balls, KDF ceramic balls, or a combination of both, efficiently adsorbing and filtering metal impurities with a broad-spectrum antibacterial rate of ≥99%. The dual filtration system, with its sequential upper and lower layers, ensures effective purification. Furthermore, in practice, the lifespan of ceramic balls 309 is significantly longer than that of filter cotton 305. Placing the filter cotton 305 in an open space allows for easy access and replacement, and users can directly replace it themselves without frequently replacing the entire filter box 300, effectively improving user convenience and reducing long-term operating costs. Other filter media materials can also be used as needed, but these are not exhaustive.

[0042] This embodiment uses a combination of filter cotton 305 and ceramic balls 309 to integrate filtration and antibacterial properties. Currently, most filter cartridges on the market only have filtration functions and lack antibacterial capabilities. Common filter cartridge components are ion exchange resin and activated carbon, which filter heavy metals and adsorb odors. To achieve antibacterial properties within the filter cartridge itself, silver ions or KDF are often added, but they are still encapsulated in the same carrier. When the antibacterial component is still within its expiration date, but the filter component has expired and is no longer usable, the entire cartridge must be replaced, reducing utilization and increasing cost. This embodiment uses a double-layer structure, allowing the primary filter material (primarily responsible for filtration) and the secondary filter material (responsible for antibacterial functions) to be independently separated. When the filter element expires, it can be replaced individually without replacing the longer-lasting antibacterial component. Furthermore, the filter cartridge 300 is a single, integrated structure, which is simpler, easier to use, and lower in cost.

[0043] Furthermore, in practice, the filter cotton 305 can be preferably configured with two sections along its length. The first section contains activated carbon, and the second section contains ion exchange resin. This achieves a multi-layer filtration effect within the filter cotton 305 itself. The activated carbon adsorbs odors and filters the water, while the ion exchange resin effectively filters heavy metals, enhancing the overall filtration effect. To further improve the ease of replacement for users, the upper filter layer has inwardly extending limiting portions 307 on both sides of its top. These limiting portions restrict the ends of the lower filter cotton 305, preventing it from detaching from the open space.

[0044] In practice, the drainage channel 303 is disposed on the outer wall of the filter box 300 and communicates with the filtration space, so that the water after multiple filtrations can be discharged outwards. Specifically, the outer wall of the filter box 300 may include an outer wall 301 that surrounds the outer side along the axial direction and a bottom wall 302 at the bottom, with the outer wall 301 and the bottom wall 302 together forming the filtration space. The drainage channel 303 may be opened on the bottom wall 302 or on the outer wall 301, either at the top or bottom of the outer wall 301, as long as it allows the filtered water to be discharged outwards. More preferably, the bottom wall 302 of the filter box 300 closes the bottom of the lower filtration area, and the drainage channel 303 is opened on the outer wall 301 of the filter box 300.

[0045] To further enhance the purification effect, preferably, the drainage channel 303 is also equipped with an outlet filter layer 312. The outlet filter layer 312 can also be made of PP filter cotton, which effectively filters hair, etc. The water filtered by the filter cotton 305 and ceramic balls 309 is discharged after passing through the outlet filter layer 312. Specifically, the position of the outlet filter layer 312 varies depending on the location of the drainage channel 303. For example, when the drainage channel 303 is located on the bottom wall 302, that is, when the bottom wall 302 is not closed but has a through channel for water supply and drainage, PP filter cotton can be laid directly on the inner side of the bottom wall 302, that is, below the ceramic balls 309, to achieve a third layer of filtration. When the bottom wall 302 closes the bottom of the lower filtration area, a drainage channel 303 can be opened at the bottom of the outer wall 301, and the drainage channel 303 extends downward to the surface of the bottom wall 302. PP filter cotton is arranged vertically to cover the drainage channel 303, which can also achieve a third layer of filtration. (The text repeats itself here, so the translation stops.) Figures 1-4 As shown, in this embodiment, the bottom wall 302 of the filter box 300 seals the bottom of the lower filter layer, and the drainage channel 303 is opened at the bottom of the outer side wall 301 of the filter box 300, forming a filtration space within the outer side wall 301. The bottom wall 302 can be made of a transparent or translucent material.

[0046] To facilitate the stable installation of the effluent filter layer 312, further, in conjunction with Figure 5As shown, multiple sets of inner positioning ribs 311 are provided at intervals along the length of the water outlet filter layer 312 on the inner side of the outer wall 301. The water outlet filter layer 312 is clamped between the outer wall 301 and the inner positioning ribs 311. Multiple sets of inner positioning ribs 311 extend vertically, ensuring effective positioning along the entire length direction. They form a slot space between the inner and outer walls 301 for inserting the water outlet filter layer 312. In actual installation, the water outlet filter layer 312 is first inserted and positioned, and then the bottom wall 302 is ultrasonically fixed to the bottom surface of the outer wall 301. The water outlet filter layer 312 completely covers the drainage channel 303. Preferably, the drainage channel 303 extends in a long strip along the circumferential direction at the bottom of the outer wall 301, providing a smooth and wide flow path. Correspondingly, the outer wall 301 has a downwardly extending outer positioning part 308 in the middle of the drainage channel 303. The water outlet filter layer is clamped inside the outer positioning part 308, ensuring effective clamping along the length direction from the outside. The drainage channel 303 can be achieved by opening slots that penetrate the interior on both sides of the bottom of the outer wall 301. An outer positioning part 308 is formed between the two slots, and the two ends of the water outlet filter layer 312 are clamped and positioned by the wall surface of the outer wall 301 at the end of the slot.

[0047] Furthermore, to facilitate the installation and replacement of the filter cartridge 300 as a whole, a detachable connection is required between the filter cartridge 300 and the water dispenser components. Accordingly, the filter cartridge 300 also includes an inner fixing part 304 for installation and fixation. The filtration space surrounds the outer side of the inner fixing part 304. Taking a fan-shaped filter cartridge 300 as an example, the filtration space is located on the outer area of ​​the fan shape, and the inner side is the inner fixing part 304. In practice, magnetic adsorption installation can be used. Corresponding to the water dispenser components having adsorption magnets, a metal sheet structure that can cooperate with adsorption can be provided on the top surface of the inner fixing part 304. Specifically, a fixing groove 306 can be provided, with the metal sheet structure encased within the fixing groove for installation. Alternatively, the design can be reversed, i.e., a magnetic structure can be provided on the inner fixing part 304.

[0048] Combination Figure 7 and Figure 8 As shown, this embodiment also provides a pet drinking stand 200, which is configured to be installed on a water tank 100. The top of the drinking stand 200 has a water storage area, and a drain outlet 211 is formed on the drinking stand 200. The drain outlet 211 is used to return the water in the water storage area to the water tank 100. The bottom of the drinking stand 200 is provided with a filter box 300 as described above at the position corresponding to the drain outlet 211.

[0049] Furthermore, the drinking stand 200 also features a water outlet 213 for discharging water into the water storage area. Specifically, the drinking stand 200 includes a power unit and a liquid extraction pipe at the bottom. A power pump draws water from the water tank 100 to the water outlet 213, discharging it into the water storage area for drinking. Water also circulates back into the water tank 100 via the drain outlet 211, where it is effectively filtered by the filter box 300. The filter box 300 is detachably attached to the bottom of the drinking stand 200 using a magnetic attachment, allowing for easy removal and replacement of the first filter media, making it convenient to use.

[0050] This embodiment also provides a pet water fountain that uses the filter cartridge 300 described above to filter water. More specifically, it includes a water tank 100, and the top of the water tank 100 is detachably fitted with the drinking seat 200 described above, to achieve circulating filtration of pet drinking water.

[0051] The above description is illustrative of the present invention and its embodiments. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
