Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter element technology, specifically to a gel-type filter element. Background Technology
[0002] Currently used water purification devices often use filter covers and filter cartridges that are spin-welded together. During spin-welding, the plastic material produced by the melting of the filter cover and filter cartridge will overflow from the gap between the filter cover and filter cartridge and onto the surface of the filter cartridge. This requires subsequent processes to clean the overflowed plastic material or to process a cover to cover it, which reduces the efficiency of filter cartridge production and increases production costs. Utility Model Content
[0003] The purpose of this invention is to provide a glue-encapsulated filter element that can prevent the overflow of plastic materials and improve the efficiency of filter element production.
[0004] To achieve the above objectives, the solution of this utility model is as follows: A type of gel-coated filter element includes a filter barrel and a filter cover. The upper end of the filter barrel has an opening for inserting the filter components into the filter barrel. The filter cover is welded to the opening. The filter barrel is provided with an inlet channel and an outlet channel. Water flows into the filter barrel through the inlet channel, passes through the filter components, and flows out through the outlet channel. An overflow space is formed between the side wall of the filter barrel and the side wall of the filter cover. The overflow space is used for the flow of plastic colloid produced by the spin welding of the filter cover and the filter barrel. Furthermore, the filter cover is inserted into the filter barrel through the opening and is spin-welded together with the filter barrel. An overflow groove is provided on the outer side wall of the filter cover. When the filter cover is spin-welded to the opening of the filter barrel, the overflow groove and the inner side wall of the filter barrel together form the overflow space.
[0005] Furthermore, the overflow groove is U-shaped and surrounds the outer wall of the filter cover.
[0006] Furthermore, the filter cover is inserted into the filter barrel through the opening and is spin-welded together with the filter barrel. An overflow groove is recessed outward on the inner side wall at the opening of the filter barrel. When the filter cover is spin-welded to the opening of the filter barrel, the overflow groove and the outer side wall of the filter cover together form the overflow space.
[0007] Furthermore, the overflow groove is U-shaped and surrounds the inner wall of the filter bucket opening.
[0008] Furthermore, the top side of the filter cover is provided with a snap-fit part, which is used to snap into the power output end of the spin melting machine so that the filter cover can be rotated by the power output end of the spin melting machine.
[0009] Furthermore, a first wedge surface is provided at the lower end of the outer wall of the filter cover, and a second wedge surface is provided on the inner wall of the filter barrel opening. When the filter cover is inserted into the filter barrel, the first wedge surface and the second wedge surface can abut against each other. During the spin welding of the filter cover and the filter barrel, the rotation of the filter cover causes the first wedge surface and the second wedge surface to rub against each other and melt to achieve welding.
[0010] Furthermore, the overflow space is formed above the contact point between the first and second wedge surfaces.
[0011] Furthermore, the first wedge surface is spin-welded to the lower end of the second wedge surface, and a welding wall is provided on the upper side of the first wedge surface. When the first wedge surface and the second wedge surface are spin-welded, the welding wall is also spin-welded to the second wedge surface at the same time.
[0012] Furthermore, a first step surface is provided at the opening of the filter barrel and on the upper side of the second wedge surface, and a second step surface is also formed at the upper end of the welded wall. When the welded wall, the first wedge surface and the second wedge surface are spun welded together, the second step surface overlaps the first step surface and the two are spun welded together.
[0013] After adopting the above solution, the beneficial effects of this utility model are as follows: The present invention provides an overflow space between the side wall of the filter barrel and the side wall of the filter cover. The overflow space is used for the flow of plastic colloid produced during the spin welding of the filter cover and the filter barrel, which effectively prevents the molten plastic colloid from overflowing. During the production process of the filter element, there is no need for subsequent cleaning steps to clean the overflowed plastic material, nor is there a need to process the decorative cover, which shortens the processing time of a single filter element, helps to improve production efficiency and reduce production costs. The overflow space provides a dedicated space for the molten plastic generated during spin welding, allowing the overflowing plastic to flow into the overflow space and preventing the plastic from spilling onto the outer surface of the filter element. This eliminates appearance defects caused by plastic leakage and ensures the overall aesthetics of the filter element.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0016] like Figures 1 to 6 As shown, this embodiment provides a gel-type filter element 1. The filter element 1 includes a filter barrel 11 and a filter cover 12. The upper end of the filter barrel 11 has an opening 111 for the filter component to be inserted into the filter barrel 11. The filter cover 12 is spin-welded to the opening 111. The filter barrel 11 is provided with a water inlet channel and a water outlet channel. Water flows into the filter barrel 11 through the water inlet channel, passes through the filter component, and flows out from the water outlet channel. An overflow space 13 is formed between the side wall of the filter barrel 11 and the side wall of the filter cover 12. The overflow space 13 is used for the flow of plastic colloid generated during the spin welding of the filter cover 12 and the filter barrel 11. like Figures 2 to 3 As shown, in one embodiment, the filter cover 12 is inserted into the filter barrel 11 through the opening 111 and is spin-welded together with the filter barrel 11. An overflow groove 14 is recessed inward on the outer side wall of the filter cover 12. When the filter cover 12 is spin-welded to the opening 111 of the filter barrel 11, the overflow groove 14 and the inner side wall of the filter barrel 11 together form the overflow space 13.
[0017] Specifically, the overflow groove 14 is U-shaped and surrounds the outer wall of the filter cover 12.
[0018] In another embodiment, the filter cover 12 is inserted into the filter barrel 11 through the opening 111 and is spin-welded together with the filter barrel 11. An overflow groove 14 is recessed outward on the inner side wall of the filter barrel 11 at the opening 111. When the filter cover 12 is spin-welded to the opening 111 of the filter barrel 11, the overflow groove 14 and the outer side wall of the filter cover 12 together form the overflow space 13.
[0019] Specifically, the overflow groove 14 is U-shaped and surrounds the inner wall of the filter bucket 11 at the opening 111.
[0020] like Figure 4 The top side of the filter cover 12 is provided with a snap-fit part 15, which is used to snap with the power output end of the spin melting machine so that the filter cover 12 can be rotated by the power output end of the spin melting machine. The snap-fit part 15 is specifically a snap-fit protrusion or a snap-fit groove, which can snap with the power output end of the spin melting machine.
[0021] like Figure 3 , Figure 6 As shown, the lower end of the outer wall of the filter cover 12 is provided with a first wedge surface 121, and the inner wall of the opening 111 of the filter barrel 11 is provided with a second wedge surface 112. When the filter cover 12 is inserted into the filter barrel 11, the first wedge surface 121 can abut against the second wedge surface 112. When the filter cover 12 and the filter barrel 11 are spin-welded, the filter cover 12 rotates so that the first wedge surface 121 can rub against the second wedge surface 112 to melt and achieve welding.
[0022] Specifically, such as Figure 3 As shown, the overflow space 13 is formed above the contact point of the first wedge surface 121 and the second wedge surface 112. It can be understood that the first wedge surface 121 and the second wedge surface 112 also have a guiding function. When the first wedge surface 121 and the second wedge surface 112 are spin-welded, the molten plastic can flow upward through the guiding function of the first wedge surface 121 and the second wedge surface 112, and finally flow into the overflow space 13.
[0023] Specifically, such as Figure 3 , Figure 6 As shown, the first wedge surface 121 is spin-welded to the lower end of the second wedge surface 112. A welding wall 122 is provided on the upper side of the first wedge surface 121. When the first wedge surface 121 and the second wedge surface 112 are spin-welded, the welding wall 122 is also spin-welded to the second wedge surface 112.
[0024] Specifically, such as Figure 4 As shown, a first stepped surface 113 is provided at the opening 111 of the filter barrel 11 and on the upper side of the second inclined wedge surface 112. The first stepped surface 113 surrounds the inner wall of the filter barrel 11. Figure 6 As shown, a second step surface 123 is also formed at the upper end of the welded wall 122. The second step surface 123 surrounds the outer wall of the filter cover 12. When the welded wall 122, the first wedge surface 121 and the second wedge surface 112 are spin-welded, the second step surface 123 rests on the first step surface 113 and the two are spin-welded together. The molten plastic material also overflows into the overflow space 13.
[0025] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
[0026] The above description is only a preferred embodiment of this utility model and is not a limitation on the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
