Description

Double-shell type filter element assembly Technical Field The utility model belongs to the field of water purifiers, and particularly relates to a double-shell type filter element assembly. Background The filter element assembly mainly comprises a connector and a filter element, and the filter element comprises a shell, an upper end cover and a lower end cover and a shell. The existing shell is made of pure plastic material, and can bear pressure of the structure only by reaching a very thick thickness, or the shell is made of stainless steel or aluminum alloy, but because the aluminum alloy is used as the shell, a layer of film is required to be coated inside the shell to prevent metal ions from affecting purified water, so that the contact between the aluminum alloy and a water source is isolated. The existing coating process is complex, has extremely high process requirements, and can be completed only by large-scale spraying equipment, so that the time is consumed, and the enterprise operation cost is increased. Based on this, a need exists for a new filter element assembly that can be implemented as an aluminum housing while avoiding the use of complex processes to coat the inner walls with a coating material. Disclosure of utility model The utility model aims to solve the technical problem of providing the double-shell type filter element assembly, wherein the filter element assembly adopts aluminum alloy as a shell to play a role in structural bearing, and can realize safe water purification environment without a complex spraying process, thereby effectively reducing the enterprise cost and the production convenience. The double-shell type filter element assembly comprises a filter element, wherein the filter element comprises an aluminum alloy shell, a filter element body arranged in the aluminum alloy shell, and a plastic inner shell arranged between the filter element body and the aluminum alloy shell and used for sealing and isolating the filter element body and the aluminum alloy shell. Further, the thickness of the aluminum alloy outer shell adopted by the filter element assembly can be 1-2mm, and the thickness of the plastic inner shell can be 1-2mm. Further, the filter element body adopted by the filter element assembly comprises a filter material, and an upper end cover and a lower end cover which are respectively arranged at two ends of the filter material. Furthermore, the inside wall of the plastic inner shell that this filter core subassembly adopted all with the lateral wall laminating of upper end cover and lower end cover sets up, and is equipped with the sealing washer between the plastic inner shell all and upper end cover and the lower end cover. Further, the aluminum alloy shell adopted by the filter element component is of a hollow structure with a closed bottom end, and the top end of the aluminum alloy shell is fixedly connected with the upper end cover. Further, the aluminum alloy shell adopted by the filter element component is of a penetrating hollow structure, and the top end and the bottom end of the aluminum alloy shell are fixedly connected with the upper end cover and the lower end cover respectively. Further, the filter element assembly also comprises a connector connected with the filter element and a locking device which is arranged in the connector and can realize the separable connection of the filter element and the connector. Preferably, the locking device comprises a slide plate fixing cover provided with a central through hole and arranged at the bottom end of the joint, a button slide block provided with the central through hole and slidably arranged between the joint and the slide plate fixing cover, grooves arranged on two side surfaces of the central through hole of the button slide block at intervals, and an elastic element with one end arranged at the joint and the other end connected with the tail end of the button slide block. Further, the upper end cover of the filter element assembly is provided with a convex block corresponding to the groove, and the surface of the groove contacted with the convex block is an inclined surface. Compared with the prior art, the double-shell type filter element assembly has the advantages that through the arrangement of the aluminum alloy outer shell and the plastic inner shell, the structure bearing function is achieved through the aluminum alloy outer shell, the sealing and isolation functions are achieved through the plastic inner shell, and the key point is that through the arrangement of the double-shell type structure, the inner side wall of the aluminum alloy outer shell can be effectively prevented from being sprayed by adopting a complex spraying process, and the enterprise cost and the production convenience are effectively reduced.
