Title:
AIR PURIFIER
Document Type and Number:
WIPO Patent Application WO/2018/214091
Kind Code:
A1
Abstract:
Disclosed is an air purifier having a filter (2), an air pressure sensor (6), a warning module and a control module, wherein the air pressure sensor (6) is used for collecting an air pressure value of air after same flows through the filter; the warning module is used for providing, for a user, information about the degree of damage of the filter; and the control module can adjust a working state of the warning module according to the air pressure value collected by the air pressure sensor (6). The air pressure sensor (6) includes: a collection portion (6E); a rectification grid (6C) for rectifying the air after same flows through the filter (2); and a flow guide channel (6D) located between the collection portion (6E) and the rectification grid (6C), wherein the collection portion (6E) is used for collecting an air pressure value of the air flowing in from the flow guide channel (6D). By rectifying the air after same flows through the filter (2) by means of the rectification grid (6C), an eddy can be changed into a laminar flow, and then flows to the collection portion (6E) along the flow guide channel (6D), thus preventing the eddy from affecting the precision of the collected air pressure value.
