When the dust remover is kept in a certain air pressure range, the dust remover is indicated to be in a normal working state, if the inside of the dust remover exceeds or is lower than the certain air pressure range, the abnormality of the dust remover is indicated, so that the air pressure inside the dust remover needs to be detected, and when the inside air pressure of the dust remover is abnormal, an operator needs to pause the dust remover and check the internal structure of the dust remover. In order to realize the detection to the inside atmospheric pressure of dust remover, as shown in fig. 2, this dust remover includes shell 1, atmospheric pressure determine module 6 and coupling assembling 4, and the inside mainly used of shell 1 is collected the dust, and atmospheric pressure determine module 6 is used for detecting the pressure value, and coupling assembling 4 is used for realizing the inside of shell 1 and the intercommunication of atmospheric pressure determine module 6. Coupling assembling 4 is connected with shell 1's inside and atmospheric pressure determine module 6 respectively, has seted up third through hole 41 on coupling assembling 4, and the one end of third through hole 41 is linked together with shell 1's inside, and the other end and the atmospheric pressure determine module 6 of third through hole 41 are linked together, and shell 1 inside gas transmits atmospheric pressure determine module 6 through third through hole 41, and atmospheric pressure determine module 6 can realize the detection to shell 1 internal gas pressure. Specifically, the air pressure detecting assembly 6 may be selected as an air pressure sensor or a differential air pressure sensor, and the present embodiment preferably uses a differential air pressure sensor capable of detecting and comparing a pressure difference between the air pressure in the housing 1 and the external atmospheric pressure.

Because the collection to the dust is mainly used for in the shell 1, so the dust in the shell 1 also can enter into atmospheric pressure determine module 6 department through third through-hole 41, because atmospheric pressure determine module 6 is the precision measurement instrument, the dust can influence atmospheric pressure determine module 6's detection precision, can't realize atmospheric pressure determine module 6 to the more accurate detection of shell 1 inside atmospheric pressure. In order to solve the above problems, the dust remover needs to increase the filter assembly 5 used for filtering dust between the inside of the shell 1 and the air pressure detection assembly 6, the filter assembly 5 can be a dust filter plate or a dust filter screen, the dust filter plate is thick, so the filter effect of the dust filter plate is good, more than 95% of dust possibly entering the air pressure detection assembly 6 can be filtered, and the detection precision and the service life of the air pressure detection assembly 6 can be effectively improved.
