Water purifier with characteristic of multiple circulation filtrations

Abstract

The present invention relates to the technical field of water purification equipment, especially to a water purifier with a characteristic of multiple circulation filtrations. The water purifier comprises a water storage barrel, wherein a filtration cylinder is downward arranged inside the upper cover of the water storage barrel, the upper end of the water storage barrel is provided with a water inlet and a water outlet, the water inlet is connected with the water inlet end of the filtration cylinder, and a circulation pump for controlling action of a circuit board is arranged in the upper cover. According to the present invention, under a non-use state, water in the machine is in a movement state so as to achieve the multiple purification filtration function; when the supplied water is used, the circulation pump stops working, water entering from the water inlet is filtered and purified through the filtration cylinder and slowly flows upward from the position below the filtration cylinder along with the outflow of the purified water on the water outlet, and the supplied water on the water outlet is generally the purified water being subjected to multiple circulations in the water storage barrel; when the water purifier is not used, the circulation pump performs circulation filtration, and the multiple filtration cores are not required to be arranged; and the circulation device is arranged inside the water storage barrel, such that the structure is compact, and promotion is easily achieved.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purifier for multiple circulation filtration. Background technique [0002] Existing water purifiers generally use multiple filter elements or filter layers. Water enters the machine from the water inlet and is filtered through several filter elements instantaneously; while the water in the machine is still when it is not in use, it belongs to one-time filtration. The final water quality is affected by the filtration time and filter material, and the filtration effect is obviously different. In addition, the multiple filter elements set will lead to a huge product structure, high cost, and the popularization and application will be affected to a certain extent. Contents of the invention [0003] The present invention aims at the deficiencies existing in current water purifiers, and provides a water purifier for multiple circulation filtration that s...
