Double-channel filter capable of automatically closing assembly port during replacement

Abstract

The invention relates to a double-channel filter capable of automatically closing assembly hole during replacement. The double-channel filter comprises a filter body, wherein the filter body is composed of an upper cover assembly and a tank assembly; the upper cover assembly comprises an upper cover and an automatic closing mechanism arranged inside the upper cover; a raw water inlet channel, a raw water outlet channel, a purified water outlet channel and an assembly hole are formed in the upper cover; the raw water inlet channel is communicated with the raw water outlet channel; a plurality of water inlet holes are peripherally formed in the water inlet end of the purified water outlet channel; the tank assembly comprises a tank body and a filtering mechanism arranged in the tank body coaxially; a raw water cavity through which raw water passes exists between the two; and the height of an inner cavity of the filtering mechanism is larger than the height from the bottom of the tank body to the upper end of the water inlet hole. According to the double-channel filter disclosed by the invention, the problem that a main water channel switch of running water needs to be frequently subjected to on-off operations before replacing an anti-scaling filter material is solved. In addition, the double-channel filter has the double channel function so as to match intelligent pedestal pans and application occasions having the same requirements thereof.

Description

technical field [0001] The invention relates to a double-channel filter capable of automatically closing an assembly port when being replaced, and belongs to the technical field of water purification equipment. Background technique [0002] The filter in the prior art includes: a water inlet and outlet mechanism, a machine head connected with the water inlet and outlet mechanism, and a filter bottle connected with the machine head, and a filter mechanism is arranged in the filter bottle. During use, water flows into the gap between the filter bottle and the filter mechanism from the water inlet, flows into the center of the filter mechanism after being filtered by the filter mechanism, and then flows from the center of the filter mechanism to the water outlet. [0003] In the existing filter, the filter mechanism will be blocked after long-term use, and needs to be replaced or cleaned. However, the water inlet and outlet cannot be automatically closed during maintenance and ...

Problems solved by technology

[0003] In the existing filter, the filter mechanism will be blocked after long-term use, and needs to be replaced or cleaned. However, the water inlet and outlet cannot be automatically closed during maintenance and replacement. Before replacing the filter mechanism, it is necessary to frequently switch on and off the main waterway switch of tap water, and there are switch misoperations. Causes the occurrence of lasing water injuries, especially the possible injuries caused by hot water pipes, which is very inconvenient to operate

[0004] In addition, with the improvement of people's living standards, intelligent toilets are more and more widely used. The water used in intelligent toilets needs to be treated differently according to different needs. The water outlet is sufficient, but the flushing water for private parts needs to be hygienic and safe, and needs to be purified. The filter in the prior art does not have a dual-channel function to match the intelligent toilet and its applications with the same requirements. The present invention aims to solve this technical problem
