Background technology
It is well known, with the increase with fire, power consumption of Modern Family, office space or public place of entertainment, fire occurs
Frequency is higher and higher, fire once occur, it is easy to occur putting out a fire to save life and property not in time, fire distinguisher lack and people on the scene it is panic,
It the unfavorable factors such as escapes slow, ultimately results in great life and property loss, in order to effectively avoid the generation of fire, in family, do
Public place or public place of entertainment etc. can all require installation smoke alarm, it be it is a kind of for detecting the inductive pick-up of smog, one
Fire hazard occurs for denier, and internal electrical loudspeaker will watchful people in time.
Notification number be CN203012901U Chinese patent disclose it is a kind of there is the smoke alarm of laser guide,
Including smoke detection chamber, central processing unit, MCU processors, radio receiving transmitting module, alarm and alarm lamp, central processing
Device is connected respectively with smoke detection chamber, MCU processors, alarm and alarm lamp, and MCU processors are connected with Laser emission mould
Block, when smoke alarm is alarmed, by laser emitting module transmitting laser light beam alignment escape opening or emergency exits, using swashing
The characteristics of light light beam penetration power is strong, correctly indicates escape direction.
If but when having a plurality of escape route in fire, since the laser emitting module of above-mentioned smoke alarm is solid
Dingan County fills, and the direction of laser light beam can not be adjusted according to actual conditions, thus can not be according to actual conditions to the launch party of laser
To being adjusted, the generation that causes the accident due to the inaccuracy of laser safety escape route is caused.
Utility model content
The purpose of this utility model is to provide a kind of smoke alarm, and Laser emission side can be adjusted according to actual conditions by having
To effect.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of smoke alarm, including smoke detection chamber and the installation cavity for being connected to smoke detection chamber, the installation cavity
On laser emitter and the adjusting apparatus for adjusting laser emitter Laser emission direction are installed, the adjusting apparatus includes
