Internal and external layered filtering kettle

Abstract

The invention discloses an internal and external layered filtering kettle. The kettle comprises: a kettle main body; a container assembly which comprises an outer shell and an inner shell spaced from the outer shell, wherein an inner cavity of the inner shell forms a raw water containing cavity, and an area between the outer shell and the inner shell forms a purified water containing cavity; a filter element assembly, wherein the input end of the filter element assembly is communicated with the raw water containing cavity through a water suction pump, and the output end of the filter element assembly is connected with a drainage pipeline for draining water towards the purified water containing cavity; a sensing device which can sense water discharged from the raw water containing cavity to the water suction pump; and a control unit assembly which is arranged in the kettle main body and is electrically connected with the sensing device and the water suction pump. According to the internal and external layered filtering kettle with the structure, to-be-filtered water and filtered water are isolated, the water is automatically and quickly filtered through the cooperation of the sensing device, the water suction pump and the filter element assembly, the water filtering efficiency is improved, and the water suction pump is controlled to work after the sensing device senses that water can be discharged from the raw water containing cavity, so that the service life of the water suction pump is prevented from being shortened when the water suction pump works in a water-free state.

Description

technical field [0001] The invention relates to an inner and outer layered filter kettle. Background technique [0002] At present, more and more people begin to pay attention to the health of drinking water, therefore, kettles with water purification function have emerged as the times require. However, the water purification pot in the prior art is usually provided with a filter element before the water outlet, and the water can be discharged after passing through the filter element by its own gravity, and the water filtration efficiency is low. In addition, when the raw water is poured into the kettle, the cover needs to be opened manually, and the cover needs to be closed manually after the water is filled, which is very inconvenient to operate. Moreover, when the cover is opened and closed, dust easily enters the kettle and pollutes the water. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the ...
