Quick locking structure for filter element

Abstract

The invention discloses a quick locking structure for a filter element. The quick locking structure comprises a locking assembly and a locking space, the locking assembly comprises a clamping part, anelastic part and a shifting part; the clamping part is provided with a locking end, the locking end can move relative to the locking space, and the locking end is provided with an extrusion surface which can be in contact with and extrude the circumferential side surface of the filter element; the elastic part is connected with the clamping part and enables the locking end to extend into the locking space; when the filter element penetrates into the locking space, the locking end extrudes the elastic part, and the elastic part generates force towards the locking end to move towards the filterelement located in the locking space; the shifting part is connected with the clamping part and can rotate automatically relative to the locking space; the shifting part can rotate relative to the locking space, so that the locking end can move relative to the locking space, and the extrusion surface extrudes or is separated from the circumferential side surface of the filter element. The quick locking structure has the advantages of realization of rapid installation and rapid unlocking of the filter element, simple and convenient operation and the like.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a quick locking structure for a filter element. Background technique [0002] Nowadays, the pollution of water resources is becoming more and more serious, and the problem of urban water safety is particularly serious. In view of the secondary pollution of tap water and the presence of harmful substances in tap water due to source water pollution, more and more households use water purifiers to filter water, making water purifiers one of the ubiquitous household appliances in daily life . The water purifier purifies the water through the filter element, but as the use time prolongs, the impurities in the water will block the filter element, so it needs to be removed and washed or replaced regularly to ensure the normal operation of the water purifier. [0003] The filter bottle fixing methods of existing water purifiers are mostly threaded or quick-connected. When r...

Problems solved by technology

When a water purifier with a vertical filter element is installed under the kitchen, due to the small vertical space under the kitchen, the line of sight is blocked when replacing the filter element, and the degree of visualization is low. Due to the limited space, the operable space is also small, making the replacement of the filter element extremely difficult. Inconvenient; for water purifiers with fewer and higher filter bottles, the filter bottles of the vertical water purifier and the whole machine have a higher center of gravity and poor stability; When the filter element is vertically arranged, the water inlet and outlet are mostly connected to the waterway plate. Due to the multi-channel sealing rings and the weight of the filter element itself, the resistance when the water inlet and outlet are taken out from the waterway plate is very large. Difference

[0005] In existing water purifiers, the internal filter elements need to be manually disassembled and replaced, which is troublesome, time-consuming, labor-intensive, low-efficiency, and has potential safety hazards, which may cause damage to the internal structure of the water purifier and cause the water purifier to The use effect becomes worse, affecting the user experience
