Abstract
The utility model relates to a detecting device, in particular to a smoke alarm. The utility model comprises an upper cover, a base seat and a bottom seat, a circuit board is arranged between the upper cover and the bottom seat, and an ABC circuit board is arranged between the base seat and the bottom seat; three through holes are arranged on arranged on the circuit board, the base seat and the bottom seat respectively, which are fixed and connected with the bolts; the base seat cooperates and connected with the bottom seat through a opening groove arranged on the periphery surface along the axial direction. The utility model mainly provides a smoke alarm which has simple and compact structure, is easy to assemble and not easy to get an electric shock, and resolves the technical problems that the structure of the exiting alarm is complex, the exiting alarm is easy to install contrariwise and easy to get an electric shock in the prior art.
Description
Technical field
The utility model relates to a kind of sniffer, relates in particular to a kind of smoke alarm.
Background technology
Now various alarm emerges in an endless stream, and also each is variant for the alarm that it adopted, and mainly is three types in ion, photoelectricity, temperature-sensitive.In early days widely used is the ion-type alarm, the radioisotopic radioactive half-life that it adopts is extremely long, can be used as the stable radioactive source that makes air ionization, this alarm is stable, reliable, but complex structure, cost are higher, and involve radioactivity and make people that environmental protection misgivings be arranged, thereby existing adopter gradually reduces.At present maximum is photo-electric smoke-sensitive alarm device, and this alarm is simpler with respect to the ion-type probe, environmental protection, cost are low.Common photoelectric smoke type alarm is made up of detecting chamber, infrared emission tube, infrared receiver tube and opto-electronic conversion components and parts etc.Someone applies for such patent: " intelligent light temperature compound detection device (CN2535804) ", it is made of cover assembly, bracket component and base assembly, cover assembly is a face-piece 2, bracket component is by darkroom box 3, Air Filter 4, support 9, circuit control panel 11, bonnet 13, shield little cover 5 and form, base assembly is made up of base, spring contact plate 16, conducting strip 18, screw assemblies 15.The detector of this structure has self-checking function, but the structure relative complex.
Summary of the invention
The utility model mainly provides a kind of simple and compact for structure, and is easy for installation, a kind of smoke alarm that is not easy to get an electric shock; Solve the existing alarm complex structure of prior art, dress is anti-easily during installation, easily the technical matters of getting an electric shock.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of smoke alarm, comprise loam cake, pedestal and base, and be provided with circuit board between described loam cake and the pedestal, between described pedestal and base, be provided with the AC circuit board; Be respectively equipped with through hole on described circuit board, pedestal and base, the three is bolted to connection; Pedestal and base open slot vertically and protruding being connected by being arranged on circumferential surface.The AC circuit board is arranged between pedestal and base, is not easy to get an electric shock, use safer.Circuit board, pedestal and base are provided with corresponding through hole, by screw the three are fixed together.In order to make the mutual position relation of base and pedestal clearer and more definite, unlikely dress just need be provided with guide locating device provided between the two in the other direction during installation.External peripheral surface at pedestal and base is provided with open slot and protruding cooperating, not only simple in structure, and positioning and guiding is good, in the circumferencial direction certain location ligand is set, only under correct direction, projection and open slot just can be connected together, and this has just well guaranteed the relative position between base and pedestal.
The number of open slot can be provided with arbitrarily according to different situations with the position of setting, open slot can be arranged on the pedestal and also can be arranged on the base, as preferably, external peripheral surface at the described pedestal in place is provided with inconsistent four the rectangular aperture grooves of width, and the width of open slot is provided with corresponding projection at the inner circumferential surface of described base.Distance and width between four rectangular aperture grooves can not wait, and have guaranteed that pedestal only is in fixing position and just can cooperates with base.
As preferably, the arrays of openings on the described pedestal is the antiparallelogram shape.The arrays of openings of antiparallelogram shape, stressed more even, connect more firm.
As preferably, between pedestal and AC circuit board, be provided with the power supply cover plate, the edge of power supply cover plate is provided with the convex edge, and the AC circuit-board card is connected in the power supply cover plate.The edge of power supply cover plate is provided with the convex edge, and the AC circuit board is put into the power supply cover plate, and the AC circuit board is held in the convex edge, AC circuit board and pedestal are separated, also just with circuit board every farther, use safer.
Therefore, the utlity model has following advantage: 1. the AC plate is arranged between base and the pedestal, uses safer; 2. be connected with projection by open slot between pedestal and base, it is more accurate to locate, and installs more convenient.
