Filter element replacing device and method and fresh air fan

Abstract

The invention relates to a filter element replacing device and method and a fresh air fan. The device comprises a filter element storage mechanism capable of accommodating at least two filter elements, and a power supply mechanism for driving a new filter element from the filter element storage mechanism to a working position and driving a filter element to be replaced to retract from the working position to the filter element storage mechanism. The filter element storage mechanism comprises a plurality of partition boards which are not smaller than the filter elements in size, and the partition boards enclose accommodating areas for accommodating the filter elements and separate the neighboring filter elements from one another. According to the filter element replacing device, the partition boards enclose the accommodating areas for accommodating the new filter elements and the old filter elements and separate the neighboring filter elements from one another, so that secondary pollution of pollutant particles on the old filter elements to the new filter elements due to the fact that the new filter elements and the old filter elements move close to each other; the power supply mechanism can convey the unused new filter element to the working position for performing air filtering operation and meanwhile convey the old filter element to be replaced back to the filter element storage mechanism for storage, so that the number of times for manual replacement and filter element cleaning can be reduced, and users can be worry-free and relieved.

Description

technical field [0001] The invention relates to fresh air blower technology, in particular to a filter element replacement device and method and a fresh air blower. Background technique [0002] For a traditional fresh air fan, the filter element for filtering air (hereinafter referred to as the filter element) is usually fixed at a certain position inside the fresh air fan. The filter element is a consumable part that needs to be manually cleaned or replaced regularly. Its service life is generally 3 to 6 months. If it is located in an area with serious air pollution, the replacement of the filter element will be more frequent, which will bring great harm to the user. A certain amount of trouble has come, especially for ceiling-mounted fresh air fans, whose frequent replacement of filter elements makes users feel even more inconvenient. [0003] In order to solve this problem, there has been a solution to automatically replace the filter element in the new fan, which can d...

AI Technical Summary

Problems solved by technology

[0004] 1. Lack of hidden storage for the used filter element, which is easy to cause secondary pollution of the unused filter element by the pollution particles on the filter element;

[0005] 2. The positioning accuracy and smoothness of the movement are lacking;

[0006] 3. The internal space of the main unit of the fresh air blower is small, while the movement mechanism of the filter element replacement device takes up a large space, which is not conducive to the conventional installation of the movement mechanism of the filter element replacement device, and limits the size of the replaceable filter element
