Description

Automatic filter update device

technical field

The present invention relates to a filter update device, in particular to an automatic filter update device, which can be applied to, for example, air-conditioning equipment, range hoods, filter equipment and sewer systems to facilitate the replacement or cleaning of filters inside the equipment or systems. net.

Background technique

With the advancement of science and technology, the design and application of various electrical equipment not only make people's lives more convenient, but also gradually develop towards the direction of improving the quality of people's living environment and health. For example, in order to improve and improve the health and comfort of people's daily life environment and space, the control of indoor temperature, humidity and/or the number of dust particles is gradually paid attention to, so air-conditioning equipment has become an indispensable part of daily life electrical equipment.

Taking the air conditioner as an example, the filter screen is an important device for collecting dust particles inside, and is used to prevent the dust particles from flowing into the equipment from the air inlet of the air conditioner and/or from flowing out to the environment through the air outlet of the air conditioner middle.
