Water purifier with convenient-to-replace filter elements

Abstract

The invention provides a water purifier with convenient-to-replace filter elements, which comprises a water purification device, the water purification device comprises filter element bases and the filter elements, each filter element base is provided with a raw water outlet column and a purified water inlet column, each filter element is provided with a raw water inlet tube and a purified water outlet tube, the raw water inlet tube is communicated with the raw water outlet column by insertion, and the purified water outlet tube is communicated with the purified water inlet column by insertion; a one-way water passage switch I is arranged in the raw water inlet tube, a one-way water passage switch II is arranged in the purified water outlet tube, and both the one-way water passage switch Iand the one-way water passage switch II are controlled to be opened by the pressure of flowing water; when both the one-way water passage switch I and the one-way water passage switch II are opened,the raw water in the water purification device can be normally filtered; and when both the one-way water passage switch I and the one-way water passage switch II are closed, the filter elements in thewater purification device can be dismounted. The water purifier prevents remaining water in the filter elements from rushing out momentarily when the filter elements are replaced, thus ensuring the safety of electronic elements in the water purifier, and moreover, the procedure of filter element replacement is simplified, so that a user can independently replace the filter elements.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a multi-stage water purifier which is convenient for replacing filter elements. Background technique [0002] The water purifier is a water treatment equipment that purifies the water quality in depth according to the requirements of water use. Its working principle is to introduce raw water into the filter element, and under the action of pressure, water molecules and beneficial minerals flow out through the filter element and pass through multi-stage filtration. , to become purified water, while bacteria, colloids, rust, suspended solids and other harmful substances are trapped in the filter element, so as to achieve the effect of filtration and purification. [0003] Chinese invention patent CN201721474086.7 discloses a water purifier for washing the face, which includes a base, a body shell, a purification device arranged in the body shell, and a water inlet and outle...

AI Technical Summary

Problems solved by technology

[0005] 1. When replacing the filter element, the residual moisture in the filter element will gushes out from the water inlet and outlet of the filter element, which will easily cause water to enter the electronic components of the water purifier, which makes it necessary to be operated by a professional when replacing the filter element. The cost;

[0006] 2. Since the filter element adopts a rotary connection structure, when the filter element shakes, it is easy to cause loosening of the connection between the filter element and the filter element seat, resulting in water leakage
