Detailed Description

As shown in fig. 1 to 4, the fire detector of the present invention mainly includes a smoke detector main body 1 and a cleaning mechanism, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the smoke sensor body 1 is a smoke sensor in the prior art, and is equipped with a smoke detection module and a wireless transmission module, the smoke detection module is used for detecting smoke, the wireless transmission module is used for uploading detection data, and the smoke detection module and the wireless transmission module are both in the prior art and are not described again here. A smoke port 11 is formed in the lower portion of the smoke detector main body, smoke enters the smoke detector main body through the smoke port, and the smoke port is prone to being blocked after long-time use or in a use environment with large dust.

The smoke detector main body is internally provided with a cleaning mechanism, as shown in fig. 3 and 4, the cleaning mechanism comprises a first micro motor 2, a driving gear 21 fixed at the output end of the first micro motor, a plurality of driven gears 22 arranged around the driving gear, a connecting rod 23 hinged and connected with the bottoms of the driven gears, and air cylinders 24 corresponding to the driven gears one by one, the first micro motor and the air cylinders are fixedly connected with the smoke detector main body, and the driving gear and the driven gears are rotatably connected with the smoke detector main body. The plurality of driven gears are arranged around the driving gear and meshed with the driving gear, and when the driving gear rotates, the driven gears can be driven to synchronously rotate. The air cylinder is a hollow structure with one open end, the closed end of the air cylinder is provided with an air inlet 241 and an air outlet 242, and air enters the air cylinder from the air inlet and then flows out from the air outlet. And one-way valves are arranged in the air inlet and the air outlet to realize the control of the flow direction of the air. The first end of the connecting rod is hinged with the driven gear, the second end of the connecting rod extends into the inner side of the air cylinder, the second end of the connecting rod is hinged with a push block 25, a mounting groove 251 convenient for mounting the connecting rod is arranged on the push block, a piston 26 made of rubber is fixed on the push block, and the piston is in close contact with the inner wall of the air cylinder to ensure the sealing property. The pull rod is driven by the driven gear to move continuously, so that the piston is driven to move continuously and reciprocally in the inflator. When the piston is far away from the closed end of the gas cylinder, the gas enters the gas cylinder through the gas inlet. When the piston rod is close to the closed end of the gas cylinder, the gas flows out through the gas outlet. The number of the air outlets is equal to that of the smoke openings, and the air outlets are positioned above the corresponding smoke openings. The movement of the piston drives the gas in the gas cylinder to flow out, and then the gas is blown to the smoke port, so that the dust accumulated in the smoke port is blown out.

In the normal use process, the first micro motor can be controlled by a program to work once at regular intervals (such as 48 hours), and then one-time cleaning is realized.

For the occasion with large dust, the smoke port cannot be thoroughly cleaned by only depending on the cleaning mechanism. For the realization to the degree of depth clearance of smog mouth, the utility model discloses still provide cleaning device, realize the cleanness to the smog mouth through cleaning device. To accommodate the use of the cleaning device, an annular groove 3 is provided in the bottom of the body of the smoke detector.

As shown in fig. 5 to 7, the cleaning assembly of the cleaning device comprises a positioning suction head 4, an air pipe 5 and a fan 6, the positioning suction head comprises two cylinders with different outer diameters and a transition part arranged between the two cylinders, and the transition part is conical. Therefore, the first end of the whole positioning suction head is large, the second end of the whole positioning suction head is small, and the first end of the positioning suction head is used for extending into the annular groove, so that the positioning suction head and the smoke detector main body are relatively fixed. A bearing 42 is arranged at the inner side of the first end of the positioning suction head, and a cleaning ring 41 is fixed on the bearing and is of a circular structure. The inner wall of the cleaning ring is provided with a cleaning brush 43, which is arranged along the radial direction of the cleaning ring. A shell 46 is fixed on the outer wall of the first end of the positioning suction head, a second micro motor 45 is arranged in the shell, a driving gear 44 is arranged at the output end of the second micro motor, a notch 47 is arranged on the side wall of the first end of the positioning suction head, and a part of the driving gear penetrates through the notch and then is meshed with teeth on the outer wall of the cleaning ring, so that the second micro motor can drive the cleaning ring to rotate, and further the cleaning of a smoke port is realized through a rotating cleaning brush. After the first end of the positioning suction head extends into the annular groove, the cleaning brush is contacted with the smoke port or extends into the smoke port for one section. The first end of the air pipe extends into the second end of the positioning suction head, and the second end of the air pipe is connected with the fan 6. The air pipe is a plastic pipe or a stainless steel pipe, so that the positioning suction head can be conveniently lifted to a high position.

When the smog port needs to be deeply cleaned, the first end of the positioning suction head of the cleaning device extends into the annular groove, and then the second micro motor and the fan are started to work. At the moment, the second micro motor acts to enable the cleaning brush to clean the smoke port, the fan acts to suck air, so that dust cleaned by the cleaning brush enters the positioning suction head, then enters the air pipe and finally enters the collection box matched with the fan, and the household dust collector is widely applied.
