Description

Technical Field

[0001] This utility model relates to a fire detection probe, belonging to the technical field of fire detectors. Background Technology

[0002] Fire detectors are devices used to detect smoke. In the initial stage of a fire, a large amount of smoke is generated, and a large amount of heat is released during the combustion process, causing the ambient temperature to rise sharply. The thermal element in the detector undergoes a physical change, thereby converting the temperature signal into an electrical signal and triggering an alarm.

[0003] The utility model patent with patent number 202223125676.2 provides a fire detection probe. This fire detection probe, through the setting of a first limiting square plate, prevents the protective filter cover from shaking between the probe and the support cylinder. The coordinated arrangement of a first support shaft, a support square rod, a fourth limiting hole, and a second limiting post achieves a long service life. The limiting square rod prevents the support plate from sliding out of the support cylinder. The coordinated arrangement of a second support shaft, a double-arc semi-support square cylinder, a third limiting post, and a support plate ensures that the top of the hollow support plate and the top of the first base are on the same plane during use, facilitating installation. However, existing fire detection probes are fixed in installation, making disassembly inconvenient for subsequent maintenance and replacement. Furthermore, dust adheres to the dustproof mesh during use, and excessive dust accumulation can affect detection sensitivity. Utility Model Content

[0004] In view of the problems in related technologies, this utility model proposes a fire detection probe to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] Preferably, the diameter of the fixing plate is larger than the diameter of the fixing seat, and the fixing seat has evenly spaced mounting holes, the diameter of which corresponds to the diameter of the detection probe body.

[0008] Preferably, the outer side of the fixed base is provided with a rotating groove, the rotating ring is disposed in the rotating groove, and gear rings are fixedly provided on the inner wall of the rotating ring and the output shaft of the drive motor, and the gear rings are meshed with each other.

[0009] Preferably, positioning rods are symmetrically provided on both sides of the connecting protrusion, and storage grooves are opened on both sides of the connecting protrusion. A reset spring is fixedly provided in the inner cavity of the storage groove, and one end of the positioning rod is embedded in the storage groove and connected to the reset spring.

[0010] Preferably, a positioning hole is provided on the connecting hole corresponding to the positioning rod, a guide strip is fixed on the inner wall of the connecting hole, and a guide groove is provided on the connecting protrusion corresponding to the guide strip.

[0011] Preferably, push rods are symmetrically slidably provided on both sides of the fixed base, the push rods are disposed in the positioning holes, and the moving end corresponds to the positioning rod.

[0012] Preferably, the detection probe body has a trapezoidal cross-section on its side, and air inlets are evenly distributed on the inclined surface. A warning light is fixedly installed at the bottom of the detection probe body.

[0013] Preferably, a cleaning rod is hinged to the bottom of the rotating rod, and a clamping spring is provided at the hinge. The position of the cleaning rod corresponds to the inclined surface of the probe body. A brush is fixed on the inner wall of the cleaning rod, and the brush is in contact with the surface of the probe body.

[0015] 1. By setting the connecting protrusion, first fix the mounting plate to the wall. Then, simply align the connecting protrusion on the probe body with the connecting hole and push the connecting protrusion into the connecting hole to achieve the connection between the probe body and the mounting base. This makes installation more convenient and facilitates subsequent maintenance and replacement.

[0016] 2. By setting a rotating ring, the drive motor can be started at regular intervals during use. The rotating ring is driven to rotate through the gear ring, thereby causing the rotating rod to rotate on the outer wall of the detection probe body.
