one end of the water inlet pipe 11 is connected with a water source, which can be municipal tap water by way of example;
the other end of the water inlet pipeline 11 is connected with one end of a check valve 12;
the other end of the check valve 12 is connected with a raw water inlet of the filtering device 13; the water flow direction of the check valve 12 is from the water inlet pipeline 11 to the raw water inlet of the filtering device 13; the filtered water outlet of the filtering device 13 provides filtered water.
The filtered water outlet of the filtering device 13 may be, for example, a water outlet of a water purifier. The filtered water may be either direct drinking water or indirect drinking water, which is not limited in this disclosure.
In the present disclosure, a water inlet end of a water purifier is provided with a check valve 12, and the filtering sequence of the water purifier is that tap water passes through the check valve 12 and a filtering device 13, and water filtered by the filtering device 13 enters a water outlet of the water purifier for a user to use.
And because the water flow direction of the check valve 12 is from the water inlet pipeline 11 to the raw water inlet of the filtering device 13, namely, tap water can only flow into the filtering device 13 from the water inlet pipeline 11, and water in the filtering device 13 cannot flow into the water source direction from the filtering device 13, water in the water purifier can be prevented from being sucked out of the water purifier and entering into the water inlet pipeline 11 due to siphon action, and the problem that the water source is polluted because impurities on the surface of the filter element are sucked into the pipeline after the filter element of the water purifier is used for a long time can be also avoided.
The present disclosure provides a water purifier, comprising: a water inlet pipeline, a check valve and a filtering device; one end of the water inlet pipeline is connected with a water source; the other end of the water inlet pipeline is connected with one end of the check valve; the other end of the check valve is connected with a raw water inlet of the filtering device; the water flow direction of the check valve is from the water inlet pipeline to the raw water inlet of the filtering device; the filtered water outlet of the filtering device provides filtered water. By arranging the check valve at the water inlet end, water in the water purifier can be prevented from flowing back to the water inlet pipeline due to negative pressure of the water inlet pipeline when the water purifier is kept stand or water is produced, and water in the water inlet pipeline is prevented from being polluted by water flowing out of the water purifier.
