[0002] The pet water dispenser consists of two parts: the water supply system and the filter element. The filter element plays the role of filtering and purifying drinking water. The filter elements on the market are basically composed of two parts: the filter element housing and the filter medium. The filter element housing is provided with a tank body for accommodating the filter medium. Since the filter element housing is mostly made of filter cotton, its strength is poor. It is easily affected by the water flow and deformed during use, causing the filter element to fit near the water outlet and block the water outlet, resulting in low filtration efficiency and unsmooth water flow in the pet water dispenser.

[0003] The method of increasing the volume of the filter medium filled into the tank can prevent the filter element from collapsing, but if the volume of the filter medium is too large, the water flow resistance will be greater, which will reduce the water output efficiency and filtration efficiency of the filter element. Therefore, it is urgent to design a filter element with high support strength, not easy to collapse, and high water output and filtration efficiency. Utility Model Content

[0030] Example:

[0031] See also Figures 1 to 5In this embodiment, a filter element includes a filter element housing 10 and a filter medium 20;

[0032] The water outlet surface of the filter element housing 10 protrudes with a plurality of filter slots 11 and at least one support slot 12; the filter medium 20 is filled in each filter slot 11, and the volume of the filter medium 20 filled in each filter slot 11 accounts for 50% to 80% of the total volume of the filter slot 11; each support slot 12 is completely filled with a sponge 30, and the thickness of the support slot 12 is greater than or equal to the filter slot 11;

[0033] The plurality of filter grooves 11 and the support grooves 12 are arranged at intervals, and at least one support groove 12 is arranged at the center of the water outlet surface of the filter element housing 10 .

[0034] In this embodiment, the volume of the filter medium 20 filled in each filter tank 11 in the filter element housing 10 accounts for 50% to 80% of the total volume of the filter tank 11, which can ensure that there is appropriate resistance when drinking water passes through the filter element, avoid excessive resistance to water flowing through the filter element due to excessive filter medium 20, and improve the water flow rate and filtration efficiency of drinking water.

[0035] At the same time, the strength of the filter element is enhanced by providing a support groove 12 filled with sponge 30 on the filter element housing 10. At least one support groove 12 is provided at the center of the filter element housing 10. Even if the filter medium 20 does not completely fill the filter groove 11, the filter element will not collapse or deform. The sponge 30 in the support groove 12 can play an adsorption role in addition to the supporting role, further improving the filtering effect of the filter element.

[0036] Specifically, the filter housing 10 can be formed by laminating two or more layers of filter cotton. The direction from the water outlet surface to the water inlet surface of the filter housing 10 is defined as the thickness direction of the filter housing 10. The projection of the filter housing 10 perpendicular to the thickness direction is a circle. The filter housing 10 is used to be assembled on the filter support of the pet water dispenser.

[0037] As an example, Figure 1 As shown, three filter slots 11 and a support slot 12 protrude from the water outlet surface of the filter housing 10. The thickness of the support slot 12 is equal to the filter slot 11. The support slot 12 is arranged at the center of the water outlet surface of the filter housing 10. The three filter slots 11 are respectively arranged at intervals with three adjacent side surfaces on the side periphery of the filter slot 11. Among them, the two filter slots 11 arranged opposite to each other are completely symmetrically arranged with respect to the center point of the filter housing 10, so as to ensure the uniformity of the drinking water filtering through the filter.

[0038] It should be known that the filter element housing 10 can also be formed by fibers or other materials with filtering functions, and the number of support grooves 12 and filter grooves 11 set in this embodiment is only a preferred example. In other embodiments, the filter grooves 11 and support grooves 12 can be reasonably set to other numbers and other positions. For example, the support grooves 12 can also be set at the periphery of the water outlet surface of the filter element housing 10.

[0039] Furthermore, if Figure 5 As shown, a porous support plate is also provided in the filter tank 11 , the thickness of the porous support plate is equal to the thickness of the filter tank 11 , and the filter medium 20 can be filled between the holes of the porous support plate and the filter tank 11 .

[0040] The porous support plate can provide uniform support for the filter element housing 10, effectively preventing the filter support from being displaced, deformed or collapsed under the water flow. The filter medium 20 is filled in the holes of the porous support plate, which can also prevent the filter medium 20 from being displaced and aggregated after passing through the water flow, avoiding local overflow or dead corner phenomena, thereby improving the filtering effect of the filter element. Drinking water flows evenly through the filter medium 20 in the holes of the porous support plate, making full use of the surface area of ​​the filter medium 20 and achieving more efficient filtration. In addition, the porous support plate also helps to evenly bear the pressure brought to the filter medium 20 by the water flow, prevent the filter medium 20 from being compacted or blocked, and maintain the stability of the filtering performance of the filter element.

[0041] It is understandable that those skilled in the art can adjust the porous support plate according to different application requirements, and the parameters such as the distribution density and thickness of the holes of the porous support plate can be flexibly configured to adapt to different types of filter media 20 and filtering requirements. For example, a sponge 30 or other cotton fiber punched holes can be selected as the porous support plate, and it is preferred that the sum of the volumes of the porous support plate and the filter medium 20 in the filter tank 11 is 80% to 90% of the total volume of the filter tank 11, while ensuring the support strength of the filter element housing 10 and reducing the circulation resistance of drinking water.

[0042] The use of sponge 30 with holes as the porous support plate is only an example. The sponge 30 has the advantages of low cost and can provide support and adsorption functions at the same time. In other embodiments, the porous support plate can also be a plastic porous support plate or a support plate made of other materials. The shape of the holes in the porous support plate is not limited to a circle, but can also be a polygon such as a triangle, rectangle, diamond, etc. The support strength of the filter element can be further improved by designing the shape of the holes.

[0043] Furthermore, if Figure 5 As shown, the holes of the porous support plate penetrate in the direction from the water outlet surface to the water inlet surface of the filter element housing 10, and the holes are spaced apart and distributed in a direction parallel to the water outlet surface.

[0044] Furthermore, if Figure 5 As shown, the porous support plate is a honeycomb support plate 13 , the honeycomb units of the honeycomb support plate 13 are distributed in a direction parallel to the water outlet surface, and the filter medium 20 can be filled into the honeycomb units of the honeycomb support plate 13 .

[0045] The honeycomb unit usually adopts a hexagonal structure, and the honeycomb support plate 13 is composed of a plurality of interconnected hexagonal honeycomb units, and the side lengths of each hexagonal honeycomb unit are equal. Such a geometric design is conducive to achieving optimal structural performance, and the connection of each honeycomb unit can evenly distribute stress.

[0046] It is understandable that the honeycomb unit may also adopt a triangular or pentagonal or other polygonal structure. The honeycomb support plate 13 can evenly disperse the pressure of the filter element housing 10 when the drinking water flows, and compared with the porous support plate with circular holes, the material utilization efficiency is high and it is lighter, and it can provide better stability and deformation resistance in the direction parallel to the water outlet surface and the thickness direction of the filter tank 11.

[0047] A plastic honeycomb support plate 13 or a honeycomb support plate 13 made of other materials may be selected. The plastic honeycomb plate (such as a honeycomb support plate 13 made of polypropylene PP, polycarbonate PC, etc.) has a low cost and can be applied to mass-produced filter elements. It is not easily damaged and can be recycled and reused, which is environmentally friendly.

[0048] Furthermore, if Figure 2 and 4 As shown, a handle portion 14 is also provided on the filter element housing 10 , and the handle portion 14 protrudes from the periphery of the filter element housing 10 toward one side of the water inlet surface of the filter element housing 10 .

[0049] The protruding design of the handle 14 makes it easier to take the filter housing 10 . The user can use the handle 14 to pull up the filter housing 10 mounted on the filter support of the pet water dispenser, thereby making installation and removal more convenient.

[0050] Furthermore, if Figure 3 As shown, the filter element housing 10 is provided with a water hole 15 penetrating the water outlet surface and the water inlet surface of the filter element housing 10 , and the water hole 15 is spaced apart from the supporting groove 12 .

[0051] Generally, the pet water dispenser also includes a water pipe, and the bottom of the filter holder is provided with a plurality of through holes, some of which are water outlets, and the other through holes are water inlets, and the two ends of the water pipe are connected to the water inlet and the water inlet hole; the filter is assembled on the filter holder of the pet water dispenser, the water outlet surface of the filter housing 10 faces the bottom of the filter holder, and the water pipe connects the water outlet of the filter holder and the water through hole 15 of the filter housing 10. When the pet water dispenser purifies drinking water, the drinking water to be purified is located on the water inlet side of the filter holder, flows to the water outlet side of the filter holder by gravity, and then enters the water storage tank through the water inlet of the filter holder, and the water supply system of the pet water dispenser pumps the purified drinking water in the water storage tank to the water outlet of the filter holder, and pumps the drinking water to the water inlet side of the filter holder through the water pipe connecting the water outlet of the filter holder and the water through hole 15 of the filter housing 10, so as to provide drinking water for the pet, thereby realizing the circulation of drinking water.

[0052] Since the filter element is more likely to collapse at the location where drinking water flows, the water holes 15 and the support grooves 12 are spaced apart so that the support grooves 12 are close to the location where drinking water flows, which can effectively prevent the filter element from collapsing and blocking the water inlet and outlet of the filter element bracket.

[0053] Furthermore, if Figure 3 As shown, a sealing portion 16 protrudes from the inner periphery of the water hole 15 . The sealing portion 16 is elastic and is used to overlap the water pipe bracket of the pet drinking fountain.

[0054] The sealing portion 16 is elastic and can fit tightly against the water pipe bracket. On the one hand, it can fix the filter element, and on the other hand, it can increase the sealing performance of the filter element, that is, prevent impurities on the water inlet side of the filter element from passing through the water hole 15 of the filter element to reach the water outlet side of the filter element, thereby preventing drinking water from bypassing the filter element.

[0055] In addition, the elastic sealing portion 16 can also adapt to water pipe brackets of different sizes and shapes, reducing the difficulty of positioning and fixing the filter element during installation, allowing the filter element to be repeatedly removed without using sealant to fix the filter element, reducing the difficulty of installation and removal of the filter element. The pet water dispenser can quickly replace the filter element. Due to the low cost of the filter element, the cost of maintaining a good water purification effect of the pet water dispenser is further reduced.

[0056] Furthermore, the sealing portion 16 is a silicone edge or soft cotton fiber.

[0057] The sealing part 16 can be made of silicone or soft cotton fiber. The soft cotton fiber can be fixed to the inner periphery of the water hole 15 of the filter element bracket by pressing. The filter element bracket, soft cotton fiber, filter medium 20 and other supporting materials can be pressed into a filter element at one time through a mold. The production process is small, the production cost is low, and it is suitable for mass production.

[0058] Furthermore, the filter medium 20 is an ion exchange resin, or medical stone, or activated carbon.

[0059] Ion exchange resin, medical stone and activated carbon can provide different water purification effects. Ion exchange resin can remove cations in drinking water, such as sodium ions, magnesium ions and calcium ions, through adsorption and ion exchange, thereby softening drinking water. Medical stone is a natural mineral that contains a variety of mineral elements, which can increase the mineral nutrients in drinking water. At the same time, natural minerals have a certain alkalinity and can also adjust the pH value of drinking water. Activated carbon can absorb organic matter in drinking water, remove the odor of water, and improve the taste and quality of drinking water.

[0060] In this embodiment, the three filter tanks 11 are respectively filled with ion exchange resin, medical stone and activated carbon, and the water purification effect of the filter element is better. It can be understood that in other embodiments, the multiple filter tanks 11 can be filled with any one of the filter media 20 of ion exchange resin, medical stone and activated carbon.

[0061] Preferably, if Figure 1 and 3 As shown, one side of the support groove 12 near the water hole 15 is an inclined surface, and the inclined surface is arc-shaped in a direction perpendicular to the thickness of the filter element housing 10. The inclined surface plays a role in avoiding the water hole 15, and at the same time can maximize the volume of the support groove 12 to improve the strength of the filter element.

[0062] This embodiment also discloses a pet drinking water dispenser, including a water supply system and the above filter element, the water supply system is connected to the filter element, and the water supply system is used to drive the drinking water to circulate from one side of the water inlet surface of the filter element to one side of the water outlet surface of the filter element.

[0063] The pet water dispenser configured in this way has a filter element with good support strength, is not easy to deform or collapse, can filter drinking water efficiently, has a strong seal between the filter element and the filter element bracket of the pet water dispenser, and is filled with multiple types of filter media 20, which has a better filtering effect on drinking water.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
