Embodiment Construction
[0036] The present invention provides a monitoring method and device for the degree of loss of filter material of an air purifier. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The invention provides a method for monitoring the loss degree of the filter material of an air purifier, such as figure 1 Said, said method comprises the following steps:
[0038] S1. Start the air purifier, and collect the first air pressure value after passing through the filter material.
[0039] When the air purifier is in the open state, the air pressure value after passing through the filter material is collected by the air pressure value collection device, ...

The invention discloses a method and a device for monitoring the loss degree of a filter material of an air purifier. The method comprises the following steps: collecting a pressure value of air passing through the filter material; comparing a preset pressure value of air under a normal condition with the collected pressure value of air, figuring out a difference between the two; and judging the loss degree of the filter material, and displaying the judged loss degree so as to realize that a user can monitor the loss degree of the filter material in the air purifier in real time. The method prevents the trouble that the user is possibly hurt and the standard for judging the loss degree of the filter material needs to be reset after the filter material is replaced or taken out because the filter material is stilled used in the air purifier after failing in effect.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to a detection method and device for monitoring the degree of loss of filter material of an air purifier. Background technique [0002] At present, air purifiers are not only used to purify the air indoors, but air purifiers are installed in many places where the air needs to be replaced or ensure air circulation. For example, air purifiers are installed on cars to replace and purify the air in the car. , to ensure that the air reaches healthy standards. [0003] The existing air purification series products can absorb, decompose or transform various air pollutants to a certain extent, thereby improving air cleanliness. The key material among them - filter material (including dust collection, deodorization, formaldehyde removal and dehumidification) , as the use time increases, its efficacy will gradually attenuate or even completely lose. If the efficacy changes of these ...
