Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

As shown in fig. 1 to 6, a smoke sensor with a filtering function comprises a mounting base 1, a housing and a smoke sensor body (not shown) mounted in the housing; the top of the mounting base is bonded with a viscose glue 2;

the shell comprises a shell 3 and an end 4 cover, the upper end of the shell is detachably connected with the mounting base, and the lower end of the shell is detachably connected with the end cover; air inlet holes are uniformly distributed in the circumferential direction of the shell, a filter screen 5 is installed on the air inlet hole of the shell, and a cleaning assembly for cleaning the filter screen is installed on the end cover;
