Description

Technical Field

[0001] The utility model relates to a water purifier, in particular to a water purifier which allows a user to replace a filter device and does not leak water when the user replaces the filter device, and a plane valve used for the water purifier. Background Art

[0002] With the improvement of people's living standards and the increasing attention to health, people have higher and higher requirements for the quality of domestic water. However, in many countries, many tap water sources are surface water, which is provided to users after being purified and disinfected by water plants. The water treatment of water by water plants is relatively extensive and is not enough to remove all impurities, such as particulate pollutants (flocculent gel, silt, and even bacteria). In addition, the aging of the tap water supply network will also bring new pollution to tap water. In order to further purify tap water and improve its cleanliness, people use a variety of water purification equipment to treat tap water. For example, tap water is filtered or ultrafiltered using a water purifier (filter material is activated carbon, PP cotton or ultrafiltration filter material, etc.), and purified water with extremely high purity is obtained using an RO membrane water purifier.

[0003] Generally, the filter device of a water purifier has a certain life span and should be replaced in time after a period of use. Therefore, the filter devices of most existing water purifiers are designed to be detachable to facilitate users to replace the filter devices. However, when users replace the filter devices, due to the water pressure in the filter element of the water purifier, the water in the filter device of the water purifier is easy to flow out and spray on the ground.
