[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a smoke detector for building fire protection facilities includes a shell 1, a filter screen 4 is arranged on the outer periphery of the lower part of the shell 1, a cleaning mechanism 5 is arranged at the lower end of the shell 1, and an installation cover 2 is connected to the upper part of the shell 1 through a connecting mechanism 3.

[0022] In this embodiment, the cleaning mechanism 5 includes a mounting shell 501, a motor 502, a plurality of cleaning rods 503 and a plurality of cleaning blocks 504. The outer periphery of the motor 502 is mounted inside the mounting shell 501, the upper part of the mounting shell 501 is mounted at the lower end of the shell 1, the lower output end of the motor 502 passes through the wall of the mounting shell 501 and is fixedly connected to one end of the cleaning rod 503, one side of the cleaning block 504 is mounted at the other end of the cleaning rod 503, and the other side of the cleaning block 504 is connected to the filter screen 4. At least three cleaning rods 503 are provided, and the cleaning block 504 is made of one of a soft brush, a sponge, rubber and a cloth.

[0023] Specifically, the driving motor 502 causes the cleaning rod 503 to drive the cleaning block 504 to rotate on the outer periphery of the lower part of the shell 1. The cleaning block 504 is made of a flexible material. Driven by the cleaning rod 503, the cleaning block 504 can wipe the dust, spider webs and other impurities on the outer periphery of the filter 4, thereby ensuring the ventilation volume of the filter 4 and ensuring the accuracy and timeliness of the detector detection.

[0024] In this embodiment, bolt holes are arranged around the mounting cover 2, and sponge rubber is arranged on the side of the mounting cover 2 away from the shell 1, and the connecting mechanism 3 includes a buckle 301, a connecting box 302, a button 303, a bayonet 304 and a spring sheet 305. The upper end of the buckle 301 is fixedly connected to the left and right sides of the lower part of the mounting cover 2, one side of the connecting box 302 is installed on the left and right sides inside the shell 1, the bayonet 304 is opened in the middle of the button 303, the outer periphery of the button 303 is slidably connected to the inside of the connecting box 302, the spring sheet 305 is arranged inside the connecting box 302, and the lower part of the buckle 301 is arranged in the middle of the bayonet 304.

[0025] Specifically, the installation cover 2 can be installed on various ceilings or walls by bolts or sponge glue. The button 303 is pressed to align the bayonet 304 with the upper and lower holes of the connection box 302, so that the buckle 301 can pass through the bayonet 304, and then the installation cover 2 and the shell 1 can be easily separated. During installation, the installation cover 2 is pressed toward the shell 1, so that the beveled edge of the lower side of the buckle 301 squeezes the bayonet 304, and then the button 303 squeezes the spring sheet 305 and moves toward the inside of the connection box 302. When the buckle 301 passes over the bayonet 304, the spring sheet 305 resets the button 303, and the edge of the bayonet 304 clamps the buckle 301, and then the shell 1 and the installation cover 2 can be connected. The operation is very convenient and easy to maintain.

[0026] Working principle:

[0027] The driving motor 502 makes the cleaning rod 503 drive the cleaning block 504 to rotate on the outer periphery of the lower part of the shell 1. The cleaning block 504 is made of a flexible material. Driven by the cleaning rod 503, the cleaning block 504 can wipe the dust, spider webs and other impurities on the outer periphery of the filter 4 to ensure the ventilation volume of the filter 4 and the accuracy and timeliness of the detector detection. The mounting cover 2 can be installed on various ceilings or walls by bolts or sponge glue. Press the button 303 to align the bayonet 304 with the upper and lower holes of the connection box 302. The buckle 301 can pass through the bayonet 304, so that the installation cover 2 and the shell 1 can be easily separated. During installation, the installation cover 2 is pressed toward the shell 1, so that the beveled edge of the lower side of the buckle 301 squeezes the bayonet 304, and then the button 303 squeezes the spring sheet 305 and moves into the connection box 302. When the buckle 301 passes over the bayonet 304, the spring sheet 305 resets the button 303, and the edge of the bayonet 304 clamps the buckle 301, so that the shell 1 and the installation cover 2 can be connected. The operation is very convenient and easy to maintain.
