High-efficiency filtration fresh air purifying device

Abstract

The invention discloses a high-efficiency filtration fresh air purifying device which comprises an enclosure. An air flue is formed in the enclosure, and a draught fan is arranged in the air flue. Theopened end of the air flue is provided with an air outlet, and a filtering assembly is detachably arranged at the air outlet. The filtering assembly further comprises a carrying plate, and the carrying plate is provided with a plurality of filtering pieces. The multiple filtering pieces are arranged at equal intervals and are further integrally formed. The cross sectional area of the ends, far away from the carrying plate, of the filtering pieces is smaller than that of the ends, close to the carrying plate, of the filtering pieces. The ends, far away from the carrying plate, of the filteringpieces are in an arc shape. According to the high-efficiency filtration fresh air purifying device, the cross section combination of the filtering pieces is similarly corrugated, and therefore the filtering superficial area within a certain space can be increased and filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of fresh air purification devices, in particular to a high-efficiency filtering fresh air purification device. Background technique [0002] The fresh air draws in fresh air from the outside, and is matched with the preset filter components in the whole machine to achieve the purpose of indoor filtration and increase the oxygen content. For fresh air fans, since the fan rotates to generate air volume circulation, noise problems are also accompanied. In order to increase the air volume, it is often necessary to increase the motor speed. After the motor speeds up, the noise problem will be aggravated, or if the size of the fan is increased, it will Increase the appearance size of the product. Therefore, it is necessary to reduce the noise at the technical level of the fresh air purifier. [0003] Moreover, because the internal size and space of the fresh air fan are limited, the size of the filter device is limited, a...

Problems solved by technology

[0003] Moreover, because the internal size and space of the fresh air fan are limited, the size of the filter device is limited, and the filtration efficiency is not high. Therefore, how to improve the filtration efficiency in a certain space is also a problem that needs to be studied at the technical level of the fresh air purifier.
