Abstract
The utility model relates to the fire hazard alarm technology field, and concretely provides a waterproof point-type detector. A water chute is arranged at the edge of a frame body. A plurality of water guiding holes are arranged at the edge of the inner ring of the frame body. The frame body is divided into an inner cavity and an outer cavity by a frame structure. A PCB circuit board can be embedded in the inner cavity. Electronic components on the PCB circuit board are distributed on the same side. A damp-proof layer is painted on the PCB circuit board. A plurality of drain holes are arranged in outer rings of a bottom cover and an upper cover. The positions of the drain holes in outer rings of the bottom cover and the upper cover corresponds with the positions of the water guiding holes in the frame body. If water drops on the plane of the frame body from above, the water discharges downwards through the water chute and the water guiding holes and does not cause damage to a detector. The waterproof structure utilizes the ingenious waterproof structure principle and has waterproof effects. The application range of a point-type fire hazard detector is widened greatly and the service life is prolonged greatly without addition of installation cost.

Described detector is smoke point detector, in described smoke point detector, be also provided with the indicator light of smoke detection module, sheet metal, radome, display working condition, the tension disc of fixed line and spring leaf, indicator light is covered with lampshade outward, the base of described external cavity and PCB combination unit is provided with the slot of laying sheet metal, and the inner surface of bottom is provided with some holddown grooves in order to fixed line.
Described detector is point heat detector, in described point heat detector, be also provided with heat detection module, upper cover shield, sheet metal, the indicator light of display working condition, the tension disc of fixed line and spring leaf, indicator light is covered with lampshade outward, the base of described external cavity and PCB combination unit is provided with the slot of laying sheet metal, and the inner surface of bottom is provided with some holddown grooves in order to fixed line.
The base of described internal cavities and PCB combination unit is for having the rectangle structure of chamfering at four drift angle places.
Osculum on described bottom and upper cover outer ring is respectively 2.
Described guiding gutter, water-guiding hole, quantity be respectively 2.
The one side that described waterproof point detector first has PCB wiring board electronic devices and components when mounted sticks liquid moistureproof wax, then is pushed in the slot in framework, after moistureproof wax condenses into solid, can form damp-proof layer.
When the osculum of current through upper cover enters behind detector inside, during through guiding gutter in framework or the past whereabouts of water-guiding hole continuation, current can be blocked by frame structure, and the osculum of taking advantage of a situation on bottom flows out detector.
The utility model compared with the existing technology, its advantage is that the utility model has designed two guiding gutters in framework by edge, inner ring edge has designed two water-guiding holes, when if top has water droplet to drain in framework plane, the flow direction of water can blocking along wall by sunk structure, water can continue to fall, and can also cannot not spread on wiring board, thereby open the effect of waterproof.While installing, first wiring board electronic devices and components face is sticked to liquid moistureproof wax simultaneously, then be pushed in the sunk structure on center, until moistureproof wax, condense into after solid, can open moistureproof effect.In sum, the utility model point type fire detector has utilized this waterproof construction principle cleverly just, has opened the effect of waterproof; In the situation that not increasing installation cost, except greatly widening the scope of application of point type fire detector, also greatly extend its useful life.
