A leak-proof self-locking filter element

Abstract

The invention discloses an anti-water leakage self locking filter element, comprising a filter cylinder and a sleeve arranged in the filter cylinder; an annular circulating inner chamber is arranged between the filter cylinder and the sleeve, the top end of the sleeve is provided with a through hole communicating the annular circulating inner chamber with an inner chamber of the sleeve, the centre of the bottom of the sleeve extends outwards to form the annular inner wall, the centre of the bottom end of the filter cylinder extends outwards to form the annular outer wall, a gap of the annular outer wall and the annular inner chamber forms an annular cavity communicated with the annular circulating inner chamber, the annular inner wall forms a cylindrical cavity communicated with the inner of the sleeve, a first sealing element for elastically sealing and plugging the annular cavity is arranged in the annular cavity, a second sealing element for elastically sealing and plugging the cylindrical cavity in the cylindrical cavity, the annular cavity or the cylindrical cavity at the bottom of the filter element serves as a water inlet and a water outlet of the filter element, the first sealing element and the second sealing element for sealing and plugging the water inlet and the water outlet are both integrated in the bottom end of the filter element, and the anti-water leakage self locking filter element is compact in structure, reasonable in design, and can effectively avoid water leakage when the filter element is changed.

Description

technical field [0001] The invention relates to the technical field of water purifier structures, in particular to a leak-proof self-locking filter element. Background technique [0002] At present, water purifiers have been widely used in China. The water purifiers can deeply filter the impurities caused by water and water pipelines, and provide people with relatively clean domestic water, thereby better protecting the health of users. Water purification The interior of the water purifier usually requires a combination of various filter elements and multi-stage filtration to achieve the ideal purification effect. The filter element is the core component of the water purifier, and the filter element is used as a consumable. After a period of use, it needs to be replaced. [0003] Existing water purifiers usually use quick connectors and connecting hoses to connect the filter elements at all levels together. The defect of this type of water purifier is that a large number of ...

Problems solved by technology

However, the structure design of this kind of filter element is complicated and the volume is large, which is not conducive to the overall layout of the water purifier. Especially under the trend of miniaturization of water purifiers and other products, this filter element structure is increasingly unable to meet market demand.
