Technical Field

[0001] The utility model belongs to the technical field of water purification filter elements, and in particular relates to a filter element structure and a filter element mold. Background Art

[0002] The pet water dispenser consists of two parts: a water supply system and a filter element. The filter element plays the role of filtering and purifying drinking water. The filter element structure of the pet water dispenser currently on the market usually installs the filter element on the filter element bracket, and the water source filtering direction of the pet water dispenser is from bottom to top. The water to be filtered enters the water storage tank below the pet water dispenser, and is driven by the water supply system to pass through the filter element, so that the purified water reaches the water outlet tank at the top of the pet water dispenser, and then passes through the return water channel of the water outlet tank to return the water in the water outlet tank to the water storage tank for circulation and purification.

[0003] This filter element structure has high requirements for the sealing assembly between the filter element bracket and the filter element, high sealing costs, and complex filter element replacement operations. If the sealing between the filter element bracket and the filter element is poor, it is easy to cause the water in the water tank to flow out through the gap between the filter element and the filter element bracket instead of the filter element, resulting in the pet's drinking water not being completely filtered and purified.

[0013] The silicone edge protruding from the outer periphery of one end of the filter element close to the water inlet side covers the top of the first overlapping portion.

[0014] Furthermore, the filter element is spaced apart from the bottom of the filter tank.

[0015] Furthermore, the filter element comprises a plurality of filter layers stacked along the first direction, the outermost filter layer on the water inlet side of the filter element is a first filter layer, and a silicone edge protrudes from the periphery of the first filter layer;

[0016] The outermost filter layer on the water outlet side of the filter element is a second filter layer, and the second filter layer is spaced apart from the bottom of the filter tank.

[0036] Example:

[0037] See also Figures 1 to 5 In this embodiment, a filter element structure includes:

[0038] The filter element 10 has two sides along the first direction, which are a water inlet side and a water outlet side, and a water inlet hole 15 is provided on the filter element 10; a silicone edge 14 is protruded from the outer periphery of one end of the filter element 10 close to the water inlet side;

[0039] A filter element support 20, the filter element support 20 comprises a filter tank 21 and a water inlet pipe 22;

[0040] The filter element 10 is placed in the filter tank 21. The bottom of the filter tank 21 is provided with a plurality of through holes, some of which are water outlets 212, and the other through holes are water inlets 213. Both ends of the water inlet pipe 22 are connected to the water inlet 213 and the water inlet hole 15.

[0041] A protruding first overlap portion 211 is provided on the wall of the filter tank 21 , and a surface of the silicone edge 14 of the filter element 10 facing the water outlet side covers the top of the first overlap portion 211 .

[0042] Since the silicone edge 14 has certain flexibility and deformation ability, its good adhesion ability enables the silicone edge 14 to fit tightly to the top of the first overlapping portion 211 , thereby increasing the sealing performance between the filter element 10 and the filter tank 21 .

[0043] like Figures 3-5 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 213 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 gravity direction, and the silicone edge 14 of the filter element 10 is tightly attached to the top of the first overlap portion 211 under the action of gravity and the flow direction of drinking water, so that the drinking water to be filtered can completely pass through the filter element 10, thereby improving the purification effect of the pet water dispenser.

[0044] Different from the related art in which the drinking water filtering direction of the pet water dispenser is from bottom to top, in actual use, the filter element structure of the utility model has the depth direction of the filter tank 21 parallel to the gravity direction, and the direction from the water inlet side to the water outlet side of the filter element 10 is arranged along the gravity direction. The drinking water filtering direction is actually from top to bottom, and the silicone edge 14 of the filter element 10 fits tightly against the first overlap portion 211 under the action of gravity, thereby improving the sealing of the filter element structure at low cost and high efficiency, thereby improving the purification efficiency of the filter element 10.

[0045] The first overlapping portion 211 may be an annular protrusion on the inner wall of the filter tank 21 , or the tank wall of the filter tank 21 may be bent toward the center of the filter tank 21 .

[0046] In addition, both ends of the water inlet pipe 22 are connected to the water inlet port 213 and the water inlet hole 15. The water inlet pipe 22 can be integrally formed with the filter tank 21, and the water inlet hole 15 can be fixed to one end of the water inlet pipe 22 by using a connection method such as snap connection, gluing or sealing.

[0047] Furthermore, if Figure 1 and 5 As shown, the water inlet pipe 22 is inserted into the water inlet hole 15 , and a silicone edge 14 is also protruded from the inner periphery of the water inlet hole 15 so that the inner periphery of the water inlet hole 15 is sealed and fitted with the outer wall of the water inlet pipe 22 .

[0048] In this embodiment, the water inlet pipe 22 is a round tube, the water inlet hole 15 is a round hole, the inner radius of the silicone edge 14 of the water inlet hole 15 can be less than or equal to the outer diameter of the water inlet pipe 22, and the silicone edge 14 has a certain elasticity and adsorption, which can make the inner periphery of the water inlet hole 15 and the outer wall of the water inlet pipe 22 seal and prevent the drinking water to be filtered from flowing out through the gap between the filter element 10 and the water inlet pipe 22. Such a setting can further improve the sealing of the filter element structure and improve the purification efficiency of drinking water.

[0049] In other embodiments, the shapes of the water inlet pipe 22 and the water inlet hole 15 may also be matching polygons or other irregular shapes. The present invention does not limit the shapes of the water inlet pipe 22 and the water inlet hole 15.

[0050] Furthermore, if Figure 2 and 5 As shown, the outer wall of the water inlet pipe 22 is provided with a protruding second overlapping portion 221 , and the silicone edge 14 of the inner periphery of the water inlet hole 15 is covered on the top of the second overlapping portion 221 on the side facing the water outlet side.

[0051] The distance from the second overlap portion 221 to the bottom of the filter tank 21 is equal to the distance from the first overlap portion 211 to the bottom of the filter tank 21. The silicone edge 14 on the inner periphery of the water inlet hole 15 covers the top of the second overlap portion 221, so that the distance from any point on the water inlet side of the filter element 10 to the bottom of the filter tank 21 is consistent. The second overlap portion 221 plays a role in positioning and limiting.

[0052] Under the action of the flow direction of drinking water and gravity, the silicone edge 14 of the water inlet hole 15 can be sealed against the second overlapping portion 221, and the second overlapping portion 221 also plays an auxiliary sealing role, further increasing the sealing performance of the filter element structure.

[0053] Furthermore, if Figures 2~5 As shown, the overlapped portion includes a first overlapped portion 211, and the filter slot 21 includes a first slot 21a and a second slot 21b connected along a first direction. Along the first direction, the projection of the first slot 21a is within the second slot 21b, and the connection between the first slot 21a and the second slot 21b forms the first overlapped portion 211;

[0054] The silicone edge 14 protruding from the outer periphery of one end of the filter element 10 close to the water inlet side covers the top of the first overlapping portion 211 .

[0055] The first groove 21 a and the second groove 21 b are integrally formed, which is conducive to mass production and manufacturing and can reduce the production cost of the filter element 10 .

[0056] Furthermore, the filter element 10 is spaced apart from the bottom of the filter tank 21 .

[0057] Such a configuration utilizes the structure of the silicone edge 14 of the filter element 10 and the first overlapping portion 211 of the filter tank 21 , and effectively prevents the problem of the filter element 10 being attached to the bottom of the filter tank 21 causing the water outlet 212 of the filter tank 21 to be blocked.

[0058] Furthermore, if Figure 1 , 4 As shown in FIG. 5 , the filter element 10 includes 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;

[0059] 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 .

[0060] The first filter layer 11 and the second filter layer 12 are respectively on both sides of the filter element 10 along the first direction. The silicone edge 14 of the first filter layer 11 covers the first overlap portion 211. The first overlap portion 211 can support the filter element 10 so that a gap is maintained between the filter element 10 and the bottom of the filter tank 21, that is, the second filter layer 12 can be spaced apart from the bottom of the filter tank 21.

[0061] Such a configuration utilizes the structure of the silicone edge 14 of the filter element 10 and the first overlapping portion 211 of the filter tank 21 , and effectively prevents the problem of the second filter layer 12 being attached to the bottom of the filter tank 21 and causing the water outlet 212 of the filter tank 21 to be blocked.

[0062] Furthermore, if Figure 1 , 4 As shown in Figures 5 and 5 , 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 and distributed along the surface of the filter layer;

[0063] Along the first direction, the projection of the water outlet 212 is located within the projection of the filter body 13 .

[0064] The filter body 13 is close to the water outlet 212 , so that the flow trajectory of drinking water passes through the filter body 13 more, thereby improving the filtering effect of the filter element 10 .

[0065] As an example, Figure 1 , 4 As shown in Figures 5 and 6, the filter element 10 includes three filter layers stacked along a first direction, and from the water inlet side of the filter element 10 to the water outlet side of the filter element 10 are the first filter layer 11, the third filter layer and the second filter layer 12 of the filter element 10. The first filter layer 11 and the second filter layer 12 are filter cotton, and the three filter layers are integrally formed.

[0066] The third filter layer includes three filter bodies 13, each of which is filled with activated carbon and / or ion adsorption resin. The first filter layer 11 and the second filter layer 12 are used for primary filtration and final filtration respectively. The filter body 13 in the third filter layer plays a functional purification role. The activated carbon can adsorb organic matter in drinking water, remove odor, pigments and harmful gases in water, and can also remove residual chlorine and some heavy metal ions in water, such as lead and mercury, to improve the taste and quality of drinking water; the ion adsorption resin can remove cations in the drinking water to be purified through adsorption and ion exchange. Through ion exchange, the ion exchange resin can effectively remove cations in the drinking water to be purified, such as sodium ions, magnesium ions and calcium ions, thereby achieving the purpose of softening and purifying drinking water.

[0067] like Figure 2 As shown, the bottom of the filter tank 21 is provided with three water outlets 212 corresponding to the three filter bodies 13 . The three water outlets 212 are circular and are evenly spaced along the bottom of the filter tank 21 .

[0068] It can be understood that the limitations on the number of filter layers, the number and shape of water outlets 212, and the filter medium filled with the filter body 13 in the above embodiments are all examples. Those skilled in the art can also set the number of filter layers, the number and shape of water outlets 212, and select the filter medium filled with the filter body 13 according to the structure of the pet water dispenser and the filtering requirements.

[0069] Furthermore, the filter element 10 is compression molded.

[0070] In this embodiment, the second filter layer 12 is placed in the lower mold of the molding mold, the filter body 13 is placed above the second filter layer 12, and the first filter layer 11 is placed on the top, covering the upper mold, and the first filter layer 11, the second filter layer 12 and the filter body 13 are molded. This filter element 10 has low production cost, can be mass-produced, and is easy to replace. The filter element 10 uses environmentally friendly filter cotton, which is recyclable and more environmentally friendly.

[0071] like Figure 6 As shown, the utility model also discloses a filter element 10 mold, and the filter element 10 mold is used to press-mold the filter element 10 as above;

[0072] The mold of the filter element 10 includes a first molding mold 31 and a second molding mold 32 . The outer peripheries of the surfaces of the first molding mold 31 and the second molding mold 32 which are arranged opposite to each other are both concavely provided with a first avoidance position 33 . The first avoidance position 33 is used to avoid the protruding silicone edge 14 on the outer periphery of the filter element 10 .

[0073] Furthermore, a second avoidance position 34 is recessed at the center of the surfaces of the first molding die 31 and the second molding die 32 that are arranged opposite to each other. The second avoidance position 34 is used to avoid the protruding silicone edge 14 on the inner periphery of the water inlet hole 15 on the filter element 10 .

[0074] When the first filter layer 11, the second filter layer 12 and the filter body 13 are not pressed together, the first filter layer 11 with the silicone edge 14 can be mass-produced, and then the first filter layer 11, the second filter layer 12 and the filter body 13 can be pressed together by a first molding die 31 and a second molding die 32 having a first avoidance position 33 and a second avoidance position 34.

[0075] Specifically, the first molding die 31 is further provided with a molding groove, and the molding groove matches the shape of the filter body 13 in the filter element 10 after molding.

[0076] The second filter layer 12 is placed in the first molding die 31, and the filter body 13 is placed on the second filter layer 12, and then the first filter layer 11 is placed on the top, covering the second molding die 32, so that the first filter layer 11, the second filter layer 12 and the filter body 13 are pressed and molded. This arrangement increases the production efficiency of the filter element 10 and reduces the cost of sealing the filter element structure.

[0077] 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.
