Rotational flow air inlet structure of counter-flushing water curtain purification device

Abstract

The invention discloses a rotational flow air inlet structure of a counter-flushing water curtain purification device. The rotational flow air inlet structure comprises a filtering box body, a counter-flushing type water curtain generator, a water collection box, a water supply box, a circulating pump and an air inlet channel, wherein the counter-flushing type water curtain generator is arranged in the filtering box body, the water collection box is communicated with the bottom of the filtering box body, the water supply box is communicated with the filter box body through a pollution-cleaning filter screen arranged in the water collection box, the circulating pump is connected between the water supply box and the counter-flushing type water curtain generator, and the air inlet channel is communicated with an air inlet and constituted by a front shell which is connected to the outside of the filtering box body and is in an arc shape; the inner wall of the air inlet channel is provided with flow guide grooves which are concentric in the axial direction, arranged in the radial direction in an encircling mode and in helical shapes, and an inlet of the air inlet channel is arranged in a mode that the air inlet direction of the air inlet channel is tangent to the guide direction of the flow guide grooves. According to the rotational flow air inlet structure, water curtains generated by the water curtain generator are utilized ingeniously for filtering air, circulatory absorption can be achieved through only a small amount of liquid, the entire volume is effectively lowered, sundries accumulated at the air inlet are further decreased by way of helical air inlet, and air inlet efficiency is improved.

Description

technical field [0001] The invention relates to a component of an air cleaner, in particular to a swirl air intake structure of a flushing water curtain purification device. Background technique [0002] With the advancement of social industrialization, the impact of industrial production on the air has gradually attracted people's attention. At present, the air quality is not optimistic. Atmospheric smog, fine particles PM2.5, and various harmful gases are the culprits of air pollution; poor air quality can easily become a major factor of disease, threatening people's health at all times . In the current situation where the overall pollution cannot be effectively controlled, how to improve the quality of the air people breathe in their lives has become a problem. Therefore, air purifiers have emerged as the times require to solve the problem of air pollution in small spaces such as indoors. Guarantee the quality of the air that people breathe as much as possible. [0003...
