Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] According to an embodiment of the utility model, a fire detector is provided.

[0026] like Figure 1-4 As shown, the fire detector according to the embodiment of the utility model includes a detection structure 1, a smoke collecting structure 2 is installed at one end of the detection structure 1, a transmission tube 3 is connected to the peripheral side of the smoke collecting structure 2, and the transmission tube 3 is connected to a branch structure 4 at one end away from the smoke collecting structure 2.

[0027] The detection structure 1 is a photoelectric smoke alarm. The smoke collection structure 2 cooperates with the transmission tube 3 and the branch structure 4 to perform an efficient smoke collection function. It can collect smoke at different points, realize active smoke collection function, improve smoke detection efficiency, and issue an alarm as early as possible in the early stage of a fire.

[0028] The detection structure 1 includes a mounting shell 101, an air intake cover 102, and a detection module 103. The mounting shell 101 is connected to the air intake cover 102.

The alarm includes a photoelectric sensor, a light source generator and a receiver. Under normal circumstances, a light beam is emitted from the light source generator to the receiver, and the light is not blocked by anything. When smoke enters the device, the smoke particles will scatter the light, causing the light beam to be interrupted or scattered onto the receiver. Once the receiver detects a change in light, the alarm will be triggered and emit a sound or other warning signal.

[0030] The smoke collecting structure 2 includes a high-speed motor 201, a fan blade 202, a guide ring 203, a first fixed rod 204, a guide pipe 205, a connecting block 206, a second fixed rod 207, a connecting cover 208, a first docking port 209, a first filter screen 210, an air outlet cover 211, and a connecting rod 212. The driving end of the high-speed motor 201 is connected to the fan blade 202, and the peripheral side of the high-speed motor 201 is fixedly connected to the guide ring 203, one end of the guide ring 203 is fixedly connected to the first fixed rod 204, and the other end of the guide ring 203 is fixedly connected to the connecting block 206.

The gas is introduced through the first port 209, and the body of the high-speed motor 201 is cooled by air when passing through the guide ring 203. The gas is then blown into the air intake hood 102, which is convenient for the detection structure 1 to detect. The first port 209 is connected to the second port 404 through the transmission tube 3, so that there is a low-pressure area in the smoke hood 401, and the air around the second filter 402 is absorbed, and then introduced into the detection structure 1 along the transmission tube 3. Since there are four smoke hoods 401 in total, the effect of air introduction at different points can be improved, and whether there is smoke in the air at different points can be efficiently detected, thereby improving the detection efficiency.

[0032] The branch structure 4 includes a smoke separation hood 401, a second filter 402, an adhesive surface 403, and a second docking port 404.
