Description
Technical field
The present invention relates to a kind of smoke alarm, specifically a kind of lateral sounding smoke alarm.
Background technique
Smoke alarm, nickname fire hazard aerosol fog alarm, smoke sensor device, smoke inductor etc..By bus-powered, bus
On can connect it is multiple, with fire alarm control unit networking, communication composition one alarm system；Conventional smoke alarm is past
Toward being that top or bottom occur, often sound is small for the smoke alarm of such sounding, causes spread scope small, how to improve cigarette
Fog siren alarm sound, expanding spread scope becomes our company's researcher's urgent problem.
Summary of the invention
The technical problem to be solved by the present invention is how to improve smoke alarm alarm sound, expand spread scope.
To solve the above-mentioned problems, the present invention adopts the following technical scheme:
The present invention is a kind of lateral sounding smoke alarm, is enclosed including upper cover, lower cover and connection upper cover and lower cover
Column；Sound hole is evenly arranged on fence；
Upper cover can be close to connection with metope, so that smoke alarm is mounted on the wall.
Sound hole is offered on fence, that is, smoke alarm side wall is provided with sound hole, and setting is enough in this way will
Buzzer generate sound transmission it is farther, touched if top/bottom is arranged in sound hole and is subject to metope/ground
It hits, to reduce volume.
Upper cover, lower cover and fence form the first cavity, are provided with pcb board in the first cavity；
Component is installed in the first cavity.
It is connected with buzzer in pcb board upper surface, and the pronunciation cover being located on buzzer；
Smoke inductor is connected in pcb board lower end surface；
Smoke inductor is used for detection gas concentration, when gas concentration is excessive, triggers the buzzer on pcb board, buzzing
The sound that device issues is propagated at sound hole by the cover that pronounces.
Pronunciation cover includes the stabilizer blade connecting with pcb board, the second cavity for placing buzzer；Upper surface is covered positioned at pronunciation
It is provided with sector open, sector open is extended downwardly along pronunciation cover short transverse；
The effect of stabilizer blade is will to pronounce to cover to be fixed on pcb board, while being provided with buzzer in pronunciation cover, buzzer hair
Sound out passes through sector open lateral propagation to sound hole, so as to improve the range of propagation.
Beneficial effects of the present invention: the present invention is a kind of lateral sounding smoke alarm, by smoke alarm side wall
On be provided with sound hole, and be equipped with pronunciation cover in buzzer upper cover, sector open is provided on pronunciation cover can only be from by sound
It propagates out at lateral openings, is propagated to outside smoke inductor through sound hole；To improve smoke alarm alarm sound, expands and pass
Broadcast range.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figs. 1-2, the present invention is on a kind of lateral sounding smoke alarm, including upper cover 1, lower cover 2 and connection
The fence 3 of lid 1 and lower cover 2；Sound hole 4 is evenly arranged on fence 3；
Upper cover can be close to connection with metope, so that smoke alarm is mounted on the wall.
Sound hole is offered on fence, that is, smoke alarm side wall is provided with sound hole, and setting is enough in this way will
Buzzer generate sound transmission it is farther, touched if top/bottom is arranged in sound hole and is subject to metope/ground
It hits, to reduce volume；
As shown in figure 3, upper cover 1, lower cover 2 and fence form the first cavity, pcb board 5 is provided in the first cavity；
Component is installed in the first cavity.
It is connected with buzzer 6 in 5 upper surface of pcb board, and the pronunciation cover 7 being located on buzzer 6；
Smoke inductor 8 is connected in 5 lower end surface of pcb board；
Smoke inductor is used for detection gas concentration, when gas concentration is excessive, triggers the buzzer on pcb board, buzzing
The sound that device issues is propagated at sound hole by the cover that pronounces.
As illustrated in figures 4-5, pronunciation cover includes the stabilizer blade 71 connecting with pcb board 5, the second cavity for placing buzzer 6
72；7 upper surfaces of pronunciation cover are provided with sector open 73, sector open 73 is extended downwardly along pronunciation 7 short transverses of cover；
The effect of stabilizer blade is will to pronounce to cover to be fixed on pcb board, while being provided with buzzer in pronunciation cover, buzzer hair
Sound out passes through sector open lateral propagation to sound hole, so as to improve the range of propagation.
Sound press >=90dB is tested at from 3 meters of smoke alarm.
The present invention is a kind of lateral sounding smoke alarm, by being provided with sound hole on smoke alarm side wall, with
And it is equipped with pronunciation cover in buzzer upper cover, being provided with sector open on pronunciation cover can only propagate out sound from lateral openings,
It is propagated to outside smoke inductor through sound hole；To improve smoke alarm alarm sound, expand spread scope.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
