[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A highly sensitive smoke alarm for intelligent fire fighting, such as Figure 1 - Figure 5 As shown, the smoke alarm body 1 includes a plurality of groups of embedded columns 11 fixed on the top, and a limiting groove 12 is provided inside the embedded column 11. The limiting groove 12 is provided to facilitate the fixing of the embedded column 11; a bottom box 2 is installed on the top of the smoke alarm body 1, and a push block 3 is movably installed on the outer wall of the bottom box 2. A slide groove 4 is provided inside the bottom box 2, a cross bar 5 is fixed on one side of the push block 3, and a protrusion 6 is fixed on one side of the cross bar 5. When the push block 3 is squeezed, the spring 7 connected to the cross bar 5 will squeeze the space, so that the protrusion 6 on the cross bar 5 moves backward. When the push block 3 is loosened, the cross bar 5 can be reset due to the elastic force of the spring 7; a socket 10 is provided on the top of the bottom box 2. The socket 10 is for embedding the embedded column 11 of the smoke alarm body 1. A limiting ring 14 is provided on the top side of the bottom box, which can fit with the limiting ring of the bottom box 2.

[0027] See also Figure 1 A limiting ring 14 is fixed on the top of the bottom box 2, and a groove 13 is opened at the bottom of the smoke alarm body 1. The inner wall of the inner groove 13 of the smoke alarm body is designed to fit with the outer wall of the limiting ring 14 on the bottom box 2, so that the bottom box 2 and the smoke alarm body 1 can be combined.

[0028] See also Figure 2 and Figure 3 A plurality of groups of bolts 15 are arranged on one side of the bottom box 2. By placing the bottom box 2 on the top of the roof and fixing it with the bolts 15, the bottom box 2 is more firmly installed on the top of the roof.

[0029] See also Figure 3 and Figure 4The top of the embedded column 11 is provided with inclined surfaces on both sides, and the inner walls of the socket 10 are provided with inclined surfaces on both sides. When the embedded column 11 is fitted with the socket 10, the inclined surfaces of the inner walls of the socket 10 and the inclined surfaces on both sides of the embedded column 11 help the embedded column 11 to play a guiding role, making it easier for the embedded column 11 to enter the interior of the socket 10.

[0030] See also Figure 5 A spring 7 is fixed inside the slide groove 4, and one end of the spring 7 is fixedly connected to the cross bar 5; sliders 8 are installed on both sides of the push block 3, and moving grooves 9 are opened on both sides of the inner wall of the slide groove 4; the number of the push blocks 3 is multiple groups, and the multiple groups of push blocks 3 are evenly distributed on the outer wall of the bottom box 2. By squeezing the push block 3 installed on one side of the bottom box 2, the cross bar 5 is moved in the moving groove 9 through the slider 8. While squeezing the spring 7, the cross bar 5 makes the protrusion 6 fixedly welded on the cross bar 5 move together. When the push block 3 is loosened, the cross bar 5 will be reset due to the elastic force of the spring 7, completing the embedding operation of the limit groove 12 and the protrusion 6 in the fixed embedded column 11 at the bottom of the smoke alarm body 1.
