Description
Technical Field
The invention belongs to the field of water purification equipment. More particularly, the present invention relates to a seal-fitted housing for a filter and a filter including the same.
Background
Along with the higher and higher requirements of people on the quality of life, attention on the safety problem of drinking water is also paid to. Nowadays, in order to purify water quality, various kinds of filters are widely installed and used by many households to filter impurities, organic pollutants, and the like in water. In domestic water, the common water purifying filter shell is mainly a cylindrical shell made of metal material. The end part of the filter is matched with a seal head to form a sealing structure, and filter elements of different forms of filter materials are arranged in the sealing structure to form various filters.
For example, see chinese patent application nos. CN 200720199368.0 and CN 201020146758.3, which disclose water purification filters employing metal shell sealing structures, the inner wall of the cylindrical shell end of such filters has an annular groove for mounting a head restraint. Generally, in order to manufacture such a water purification filter, the annular groove is first manufactured as a separate part and then integrally connected to the end of the cylindrical housing by a welding process. Therefore, the adverse effects of processing errors, welding deformation, uneven welding seams and the like in the processing equipment process are caused, and the sealing failure and water leakage accidents are easily caused during the assembly of the end socket.
For another example, see chinese patent application No. CN200820179448.4, which also discloses a water purification filter using a metal shell sealing structure, in which an annular groove structure of an inner wall of an end portion of a cylindrical case is made of a metal material of the case itself by deformation. The shape and size of the section of the groove processed by the metal deformation process are limited by the characteristics of the material, and the hidden danger of groove cracking is easily formed by stress generated in the processing process, so that the sealing head is limited to lose efficacy and water leakage accidents are caused. More importantly, the processing technology of the groove at the end part of the cylindrical shell is only suitable for metal materials such as stainless steel and the like, but not for plastic materials such as PVC and the like, and can not meet the diversified demands of the water purification product market.
Therefore, the defects that the processing technology of the groove structure at the end part of the cylinder body of the cylindrical sealing shell in the existing filter product is complicated, the sealing structure is easy to lose efficacy, water leakage accidents occur and the like are urgently needed to be overcome in the field. In addition, the design limitation that the cylinder structure is only limited to metal materials and cannot be used for non-metal materials such as plastic and the like is urgently needed to be overcome in the field.
