Examples

The following are only preferred embodiments of the present invention, and the scope of the present invention is not limited to the following examples, and all technical solutions belonging to the idea of the present invention belong to the scope of the present invention.

Referring to the attached figure 1 of the specification, the filtering structure comprises a water inlet 1, a water outlet 2 and a filtering cavity 5, wherein two check valves which are arranged in series are arranged at the water inlet of the filtering cavity 5, the two check valves comprise a first check valve 3 and a second check valve 4, and the on-off of the second check valve 4 can be controlled by controlling the on-off of the first check valve 3. The filter cavity 5 is internally provided with a filter material, and when the one-way valves are all in an open state, the filter material is dissolved and separated out, so that the residual chlorine is removed. The two one-way valves are arranged at the water inlet of the filter cavity 5 in a sealing mode, and are specifically sealed through sealing rings. And springs are arranged on the two one-way valves, and the springs are used for resetting the one-way valves.

A water purifier comprises a faucet, a faucet valve core and the filtering structure. The water inlet of the filtering structure is connected to the faucet valve core through a water inlet pipe, and the water outlet of the filtering structure is connected to the faucet through a water outlet pipe. When the faucet is closed, the waterway is closed, the one-way valve is in a closed state, and water in the cavity of the filter element cannot flow out, so that no water flows out of the faucet.

The one-way valve is specifically arranged in series such that when the faucet valve element is in an open state and the faucet is open, the water flow overcomes the spring force to jack the one-way valve open due to the pressure differential. This kind of mode through two ooff valves series connection, when needing to switch on the waterway structure in the filtration, the inside and outside pressure differential of filtration need overcome two spring force and just can switch on the waterway in the filtration completely. When the faucet is closed, the internal and external pressure difference of the filtering structure generally cannot overcome the elastic force of the two springs, so that the one-way valve is in a closed state, water in the cavity of the filter element cannot flow out at the moment, and no water flows out of the faucet.
