Description

Technical Field

[0001] This utility model relates to the technical field of water purifier filter element accessories, and in particular to a metal shell for a water purifier filter element. Background Technology

[0002] With the ever-increasing demands of modern life and technological advancements, filter cartridges typically contain KDF and activated carbon. The purpose of a filter cartridge is to purify polluted water to a state suitable for production and daily life, achieving a certain level of cleanliness. This involves removing solid particles, killing bacteria, and filtering out harmful chemicals. Typical water filters use a plastic shell to enclose the filter cartridge and other filter media; however, this type of shell has relatively weak structural strength and is easily damaged due to prolonged use or external impacts.

[0003] Currently, water purifiers with metal casings covering filter elements are available on the market. For example, patent CN204745846U discloses a water purifier with an easily detachable metal casing, comprising a filtration unit and a casing unit. The filtration unit includes a tubular filter element. The casing unit includes a top cover detachably disposed at the top of the filter element, a bottom cover detachably disposed at the bottom of the filter element, and a metal casing detachably disposed between the top cover and the bottom cover and surrounding the filter element. The top cover and the bottom cover are threadedly connected to the filter element to limit the metal casing. After removing the top cover and the bottom cover, the metal casing can be detached from the filter element, facilitating recycling or replacement. However, the operation of rotating the threaded connection is cumbersome and inconvenient to use. Utility Model Content

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] Please refer to Figure 1 and Figure 2 This is a utility model embodiment of a water purifier filter element metal housing 100. The water purifier filter element 90 includes a fixing base 91 and a filter element 92 connected to the fixing base 91. Optionally, the fixing base 91 is provided with multiple slots (not shown). The water purifier filter element metal housing 100 includes a shell 10, a positioning block 20, a limiting post 30, an inlet pipe 40, and an outlet pipe 50. The shell 10 is hollow to accommodate the filter element 92, and the fixing base 91 is installed at one end of the shell 10. A positioning block 20 is installed on the inner wall of the housing 10. The positioning block 20 supports the fixing seat 91. The positioning block 20 has a through hole 21 communicating with the housing 10 for the filter element 92 to pass through. A limiting post 30 protrudes from one end of the housing 10. There are multiple limiting posts 30, each arranged along the periphery of the housing 10. The limiting post 30 is used to insert the fixing seat 91. The feed pipe 40 and the discharge pipe 50 are respectively connected to the two sides of the housing 10. The metal housing 100 of this water purifier filter element is accommodated in the housing 10 through the filter element 92. The fixing seat 91 is supported by the housing 10 and the positioning block 20. The fixing seat 91 is inserted into the limiting post 30, which facilitates the disassembly and assembly of the fixing seat 91.

[0029] Example 1:

[0030] like Figure 1 and Figure 2As shown, the housing 10 is hollow to accommodate the filter element 92, and the fixing seat 91 is installed at one end of the housing 10. The positioning block 20 is installed on the inner side wall of the housing 10, and the positioning block 20 is used to support the fixing seat 91. The positioning block 20 has a through hole 21 communicating with the housing 10 for the filter element 92 to pass through. Optionally, a sealing gasket is installed on the positioning block 20, with one side of the sealing gasket abutting against the positioning block 20 and the other side abutting against the fixing seat 91 to improve sealing. In one embodiment, the limiting post 30 protrudes from one end of the housing 10. There are multiple limiting posts 30, each of which is arranged along the periphery of the housing 10. The limiting post 30 is used to insert the fixing seat 91. Optionally, the limiting post 30 is accommodated in a slot. The feed pipe 40 and the discharge pipe 50 are respectively connected to both sides of the housing 10.

[0031] In one embodiment, the metal housing 100 of the water purifier filter element further includes a protrusion 60, which protrudes from the bottom of the housing 10. The end of the filter element 92 away from the fixing base 91 abuts against the protrusion 60, serving to support the filter element 92. Optionally, there are multiple protrusions 60. Further, the housing 10, the positioning block 20, the limiting post 30, and the protrusion 60 are all integrally formed. The metal housing 100 of the water purifier filter element also includes multiple reinforcing ribs 70, which protrude from the outer side wall of the housing 10. Each reinforcing rib 70 is arranged along the axial direction of the housing 10, serving both to strengthen the structural strength and to provide anti-slip properties for easy gripping. The metal housing 100 of the water purifier filter element also includes a connecting piece 80, one end of which is connected to the outer side of the housing 10, and the other end protrudes from the housing 10. The connecting piece 80 is used to fix the external support mechanism. Optionally, the end of the connecting piece 80 away from the housing 10 is provided with a threaded hole 81 to accommodate a screw, and the connecting piece 80 is fixed to the external support mechanism by the screw; further, there are two connecting pieces 80.

[0032] When the filter element 92 needs to be assembled, the filter element 92 is inserted into the housing 10, the fixing seat 91 is placed on the housing 10, and the limiting post 30 is inserted into the slot of the fixing seat 91, thereby firmly fixing the fixing seat 91; when the filter element 92 needs to be disassembled, the fixing seat 91 is pulled away, so that the fixing seat 91 is disengaged from the limiting post 30, thereby allowing the filter element 92 to be disassembled from the housing 10, making disassembly and assembly convenient.

[0033] The metal housing 100 of the water purifier filter element of this utility model is housed in the housing 10 by the filter element 92. The housing 10 and the positioning block 20 cooperate to support the fixing seat 91. The fixing seat 91 is inserted into the limiting post 30, which facilitates the disassembly and assembly of the fixing seat 91. The metal housing 100 of the water purifier filter element of this utility model has a simple structure and is easy to use.

[0035] Please see Figure 3 This is the second embodiment of the water purifier filter element metal housing 100b. This embodiment is similar to the first embodiment of the water purifier filter element metal housing 100, except that the limiting post 30b in this embodiment is provided with a through hole 31b to accommodate a fastener; the fixing seat 91b is provided with a groove 911b, and the fastener passes through the groove 911b and the through hole 31b to fix the limiting post 30b and the fixing seat 91b, further tightening the fixing seat 91b and the limiting post 30b; optionally, the fastener is a screw, and both the through hole 31b and the groove 911b are threaded holes.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
