[0002] The pet drinking fountain consists of two parts: the water supply system and the filter element. The filter element plays the role of filtering and purifying drinking water. Since the outer shell of the filter element 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 outlet, resulting in low filtration efficiency and unsmooth water flow in the pet drinking fountain.

[0003] Therefore, it is urgent to design a filter element with high supporting strength, not easy to collapse, and high water outlet and filtration efficiency. Utility Model Content

[0004] The technical purpose of the utility model is to provide a filter element structure, aiming to solve the problem that the filter element structure of a pet water dispenser is prone to collapse.

[0005] In order to solve the above technical problems, the utility model is implemented as follows: a filter element structure, comprising:

[0006] A filter element, wherein two sides of the filter element along the first direction are respectively a water inlet side and a water outlet side, and a water inlet hole is provided on the filter element; a plurality of support parts are protruded from one side of the filter element close to the water outlet side;

[0007] A filter element support, the filter element support comprising a filter tank and a water inlet pipe;

[0008] The filter element is placed in the filter tank, and one end of the support portion facing away from the filter element abuts against the bottom of the filter tank;

[0009] The bottom of the filter tank is provided with a plurality of through holes, a part of the through holes are water outlets, and another part of the through holes are water inlets, and both ends of the water inlet pipe are connected with the water inlet and the water inlet holes.

[0010] Furthermore, the filter element also includes a plurality of filter bodies protruding toward the water outlet side, and each of the filter bodies is provided with at least one of the support portions.

[0011] Furthermore, the center of the water inlet hole overlaps with the projection center of the filter element along the first direction, the multiple filter bodies are evenly distributed along a circular trajectory with the water inlet hole as the center, and the support parts are evenly spaced around the center of the water inlet hole along the circumferential trajectory.

[0012] Further, along the first direction, the projection of the water outlet is located within the projection of the filter body, and the projection of the support portion does not overlap with the projection of the water outlet.

[0013] Furthermore, the filter tank wall is provided with a plurality of snap-fit ​​protrusions, the projection of the snap-fit ​​protrusions in the first direction at least partially overlaps with the projection of the filter element, and the filter element is arranged on the side of the snap-fit ​​protrusions facing the bottom of the filter tank.

[0014] Further, the direction in which the clamping protrusion protrudes from the slot wall of the filter slot is defined as the thickness direction of the clamping protrusion;

[0015] The thickness of the clamping protrusion gradually increases in a direction from away from the bottom of the filter tank to toward the bottom of the filter tank.

[0016] Furthermore, the groove wall of the filter groove is also provided with at least one positioning protrusion, and the periphery of the filter element is provided with positioning grooves matching with each of the positioning protrusions, and the positioning protrusions are penetrated through the positioning grooves.

The drinking water at the end of the filter element close to the water inlet side flows into the filter element along the direction of gravity. Since a plurality of support parts are protruding from one side of the filter element close to the water outlet side, the end of the support part facing away from the filter element can abut against the bottom of the filter tank, and the support strength of the filter element is increased through the structural improvement of the filter element, which can effectively prevent the filter element from collapsing toward the bottom of the filter tank, thereby improving the filtering efficiency and water outlet efficiency of the pet water dispenser.

[0031] Example:

[0032] See also Figures 1 to 5 , a filter element 10 structure, comprising:

[0033] The filter element 10 has two sides along the first direction, which are respectively a water inlet side and a water outlet side, and a water inlet hole 15 is provided on the filter element 10; a plurality of support portions 16 are protruded from one side of the filter element 10 close to the water outlet side;

[0034] The filter element 10 support includes a filter tank 21 and a water inlet pipe 22;

[0035] The filter element 10 is placed in the filter tank 21, and one end of the support portion 16 facing away from the filter element 10 abuts against the bottom of the filter tank 21;

[0036] The bottom of the filter tank 21 is provided with a plurality of through holes, some of which are water outlets 211 , and the other through holes are water inlets 212 . Both ends of the water inlet pipe 22 are connected to the water inlet 212 and the water inlet hole 15 .

[0037] In this embodiment, if Figure 3 As shown, the arrow direction is the flow direction of drinking water. When in use, the drinking water to be filtered is stored outside the bottom of the filter tank 21 in the pet water dispenser, and is pumped into the water inlet pipe 22 from the water inlet 212 at the bottom of the filter tank 21 and reaches the end of the filter element 10 close to the water inlet side. The drinking water at the end of the filter element 10 close to the water inlet side flows into the filter element 10 along the direction of gravity. Since a plurality of support portions 16 are protruding from one side of the filter element 10 close to the water outlet side, the end of the support portion 16 facing away from the filter element 10 can abut against the bottom of the filter tank 21. The structural improvement of the filter element 10 increases the support strength of the filter element 10, and can effectively prevent the filter element 10 from collapsing toward the bottom of the filter tank 21, thereby improving the filtration efficiency and water outlet efficiency of the pet water dispenser.

[0038] It can be understood that the first direction is the thickness direction of the filter element 10. If the filter element 10 is composed of multiple filter layers, the first direction is preferably the stacking direction of the multiple filter layers.

[0039] Preferably, the filter element 10 comprises a plurality of filter layers stacked along a first direction, the outermost filter layer on the water inlet side of the filter element 10 is a first filter layer 11, and a silicone edge 14 protrudes from the periphery of the first filter layer 11;

[0040] like Figure 2 As shown, the outermost filter layer on the water outlet side of the filter element 10 is the second filter layer 12, and the second filter layer 12 is spaced apart from the bottom of the filter tank 21. Due to the support of the support portion 16, the second filter layer 12 is not attached to the bottom of the filter tank 21 under the pressure of water, so that the second filter layer 12 and the filter tank 21 are continuously spaced apart.

[0041] It can be understood that the support portion 16 can be a hemispherical protrusion, a quasi-spherical protrusion, a columnar protrusion, a rectangular protrusion or a protrusion of other shapes, and the shapes of multiple support portions 16 can be the same or different; the support portion 16 can be arranged on the periphery of the water outlet side of the filter element 10, or can be arranged at the center of the water outlet side of the filter element 10, and multiple support portions 16 can be symmetrically distributed or asymmetrically distributed on the water outlet side of the filter element 10 with the midpoint of the water outlet side of the filter element 10 as the center.

[0042] Preferably, Figure 1 and 2 As shown, the support portion 16 is a hemispherical protrusion, and one end of the support portion 16 facing the bottom of the filter tank 21 is set to a plane, which can disperse the pressure of the flow of drinking water on the support portion 16 and improve the strength of the support portion 16. At the same time, the design of the hemispherical protrusion makes the space formed between the water outlet side of the filter element 10 and the bottom of the filter tank 21 more conducive to the flow of water, reduces the resistance of the water flow, improves the dynamic flow trajectory of the water flow, and thus improves the water outlet efficiency of the overall structure of the filter element 10.

[0043] Further, such as Figure 1 and 2 As shown, the filter element 10 further includes a plurality of filter bodies 13 protruding toward the water outlet side, and each filter body 13 is provided with at least one supporting portion 16 .

[0044] Preferably, at least one filter layer between the first filter layer 11 and the second filter layer 12 includes a plurality of filter bodies 13, the filter bodies 13 are filled with filter media, and the filter bodies 13 are spaced apart along the surface of the filter layer. Specifically, in this embodiment, the filter element 10 includes three filter layers stacked along the first direction, and the first filter layer 11, the third filter layer, and the second filter layer 12 of the filter element 10 are respectively formed from the water inlet side of the filter element 10 to the water outlet side of the filter element 10. The first filter layer 11 and the second filter layer 12 are cotton filter fibers, and the three filter layers are integrally formed.

[0045] The third filter layer includes four filter bodies 13, each of which is filled with a filter medium. The filter medium can be materials such as activated carbon or ion adsorption resin, so that the filter body 13 has different filtering effects.

[0046] It can be understood that the above-mentioned limitations on the number and shape of filter layers and the materials of filter media are only examples. Those skilled in the art can also set the number and shape of filter layers and select the filter media filled in the filter body 13 according to the structure of the pet water dispenser and the filtering requirements.

[0047] Further, such as Figure 1As shown, the center of the water inlet hole 15 overlaps with the projection center of the filter element 10 along the first direction, multiple filter bodies 13 are evenly distributed along a circular trajectory with the water inlet hole 15 as the center, and the support parts 16 are evenly spaced around the center of the water inlet hole 15 along the circumferential trajectory.

[0048] With such arrangement, on the one hand, since the plurality of filter bodies 13 and the plurality of support portions 16 are evenly spaced along a circular trajectory around the center of the water inlet hole 15, and each filter body 13 is provided with at least one support portion 16, this helps to maintain the stability of each filter body 13 in the filter tank 21, and effectively prevents the displacement and deformation of the filter element 10 when the drinking water passes through the filter body 13; on the other hand, it can ensure that the drinking water is evenly filtered when passing through the filter body 13, thereby improving the filtering effect.

[0049] Further, such as Figure 3 As shown, along the first direction, the projection of the water outlet 211 is located within the projection of the filter body 13 , and the projection of the support portion 16 does not overlap with the projection of the water outlet 211 .

[0050] To ensure that the space formed between the water outlet side of the filter element 10 and the bottom of the filter tank 21 is conducive to the circulation of drinking water, in the present embodiment, along the first direction, the projection of the support portion 16 does not overlap with the projection of the water outlet 211, thereby ensuring that the support portion 16 does not block the water outlet 211; along the first direction, the projection of the water outlet 211 is located within the projection of the filter body 13, and the filter body 13 is close to the water outlet 211, so that the flow trajectory of the drinking water passes through the filter body 13 more, thereby improving the filtering effect of the filter element 10.

[0051] Further, such as Figure 3 and 4 As shown, the groove wall of the filter groove 21 is provided with a plurality of snap-fit ​​protrusions 213 , the projection of the snap-fit ​​protrusions 213 in the first direction at least partially overlaps with the projection of the filter element 10 , and the filter element 10 is arranged on the side of the snap-fit ​​protrusions 213 facing the groove bottom of the filter groove 21 .

[0052] When in use, since the filter element 10 has a certain flexibility, the periphery of the filter element 10 can be placed on the side of the snap-fit ​​protrusion 213 facing the bottom of the filter tank 21, so that the filter element 10 is fixed between the bottom of the filter tank 21 and the snap-fit ​​protrusion 213 in a first direction, and the snap-fit ​​protrusion 213 serves to fix the filter element 10.

[0053] Multiple snap-fit ​​protrusions 213 can be arranged continuously or at intervals, such as: multiple snap-fit ​​protrusions 213 can be arranged continuously in a circular ring shape, or, multiple snap-fit ​​protrusions 213 can be arranged at uniform intervals. The distances from one side of the multiple snap-fit ​​protrusions 213 facing the bottom of the filter tank 21 to the bottom of the filter tank 21 can be the same or different, and can be set according to the requirements of the filter element 10 to adapt to filter elements 10 of different thicknesses. In this embodiment, the tank wall of the filter tank 21 is provided with two snap-fit ​​protrusions 213, and the two snap-fit ​​protrusions 213 are arranged on the opposite tank walls of the filter tank 21. It can be understood that the limitation on the number and shape of the snap-fit ​​protrusions 213 in this embodiment is only an example, and those skilled in the art can set the snap-fit ​​protrusions 213 according to actual needs.

[0054] Preferably, in this embodiment, a silicone edge 14 is provided on the periphery of the filter element 10, so that the silicone edge 14 abuts against the bottom side of the filter groove 21 facing the snap-in protrusion 213, and the elasticity of the silicone edge 14 is utilized to make the filter element 10 easier to assemble in the filter element 10 structure.

[0055] Further, such as Figure 4 As shown, the direction in which the clamping protrusion 213 protrudes from the groove wall of the filter groove 21 is defined as the thickness direction of the clamping protrusion 213;

[0056] In a direction from the bottom of the filter tank 21 away from the bottom of the filter tank 21 to the bottom of the filter tank 21 toward the bottom of the filter tank 21 , the thickness of the locking protrusion 213 gradually increases.

[0057] Such a configuration forms a slope on the side of the snap-in protrusion 213 that faces away from the bottom of the filter tank 21, thereby reducing the resistance when installing the filter element 10 and making it easier for the filter element 10 to snap into place between the snap-in protrusion 213 and the filter tank 21, thereby allowing the filter element 10 to be smoothly assembled, improving the user experience of replacing the filter element 10, and reducing the risk of damage to the filter element 10 during assembly.

[0058] Further, such as Figure 5 As shown, the groove wall of the filter groove 21 is further provided with at least one positioning protrusion 214, and the periphery of the filter element 10 is provided with positioning grooves 14a matching with each positioning protrusion 214, and the positioning protrusion 214 is penetrated through the positioning grooves 14a.

[0059] On the one hand, the positioning protrusion 214 provides positioning for the filter element 10 to be assembled into the filter groove 21, making the assembly of the filter element 10 faster, especially when the filter element 10 has a specific assembly direction requirement, the positioning protrusion 214 and the positioning groove 14a help to avoid the filter element 10 from being misplaced or offset due to improper assembly, thereby increasing the reliability of the filter element 10 and improving the efficiency of installing the filter element 10; on the other hand, when drinking water flows through the filter element 10, the flow of water may cause the filter element 10 to be displaced, and the positioning protrusion 214 and the positioning groove 14a can keep the filter element 10 in a fixed position at all times, thereby ensuring the stability of the filtering effect.

[0060] Further, such as Figure 1 As shown, a silicone edge 14 protrudes from the periphery of the filter element 10 , and a positioning groove 14 a is formed on the silicone edge 14 .

[0061] Preferably, the positioning protrusion 214 and the positioning groove 14a are interference fit. Since the positioning groove 14a is arranged on the periphery of the filter element 10, a silicone edge 14 can be used on the periphery of the filter element 10 to enhance the sealing between the positioning groove 14a and the positioning protrusion 214.

[0062] Further, such as Figure 2 As shown, the thickness of the support portion 16 along the first direction is 20% to 30% of the thickness of the filter element 10 along the first direction.

[0063] In this embodiment, the thickness of the support portion 16 along the first direction is 2 mm, so that a gap of 2 mm is formed between the water outlet side of the filter element 10 and the bottom of the filter tank 21. The gap can prevent the filter element 10 from directly contacting the bottom of the filter tank 21, and the thickness of the support portion 16 and the filter element 10 in the first direction is 20% to 30%, which can not only form a gap between the water outlet side of the filter element 10 and the bottom of the filter tank 21, but also ensure that the gap is not too large. If the gap is too large, the drinking water will not pass through the filter body 13, but will pass through the position where the filter body 13 is not set on the filter element 10. In this way, the balance between support and providing a sufficiently smooth drinking water flow path can be taken into account. In addition, the thickness of the support portion 16 and the filter element 10 in the first direction is 20% to 30%, which can also provide better support and stability for the filter element 10, avoiding the instability of the filter element 10 caused by the excessive thickness of the support portion 16.

[0064] Furthermore, the filter element 10 is compression molded.

[0065] The filter element 10 in this embodiment has low production cost, can be mass-produced, and is easy to replace. The filter element 10 can use environmentally friendly filter cotton, which is recyclable and more environmentally friendly.

[0066] 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.
