CLEANING DEVICE, AND BLOCKING MEASUREMENT METHOD FOR FILTER ELEMENT OF SAME

WIPO Patent Application WO/2022/179585

A1

A cleaning device (100) and a blocking measurement method for a filter element of the cleaning device (100). The cleaning device (100) comprises: an electric motor (22); a filter structure, which is arranged at an air inlet end and/or an air outlet end of the electric motor (22); and a measurement assembly (5), which is used for measuring at least one of the parameters of gas between the filter structure and the air inlet end and/or the air outlet end of the electric motor (22). The blocking measurement method for the filter element of the cleaning device (100) comprises the following steps: acquiring an initial pressure value measured by a measurement assembly (5); acquiring a working pressure value measured by the measurement assembly (5); and determining that a filter structure is blocked when the absolute value of the difference between the working pressure value and the initial pressure value is greater than a preset value. The method can effectively monitor the working condition of the filter structure and can accurately determine a blocking position, so as to effectively protect the normal operation of the electric motor (22) and prolong the service life of the electric motor (22), such that the service life of the cleaning device (100) is improved.
