Description
Technical field
The utility model is related to optical sensor field, more particularly to a kind of smoke detector.
Background technology
Smoke detector is typically mounted on house and other building annexes, to detect the flue gas concentration of fire possibly together
Situation simultaneously provides alarm signal.Operation principle is：Receiving and dispatching light shield component includes electroluminescent lamp and receives light lamp, under normal circumstances electroluminescent lamp
The light sent can be received by receipts light lamp, but if smog enters sensor, then the light that electroluminescent lamp is sent can be hidden by smog
Firmly cause receipts light lamp can not receive light, therefore sensor sends alarm signal.
Smoke detector is typically mounted on floor ceiling wall, and existing smoke detector needs to be dismantled after installing
Maintenance and more bother when clearing up, and false alarm, shadow can occur when entering sensor internal for mosquito or bulky grain dust
Ring the using effect of smoke detector.
Utility model content
For problem above, the utility model devises a kind of smoke detector, to solve dismounting trouble and using effect
Poor the problem of.
The technical solution of the utility model is：The smoke detector includes shell, dust preventing component, radome, wiring board group
The inserted link that can coordinate with the jack that is correspondingly arranged on base is provided with part, base and fixed support, fixed support, inserted link includes
The bar portion of two semi-cylinder structures, two bar portion tops, which are provided with, can fix the plush copper in the jack, and dust preventing component includes
Dust cap, Air Filter and dust-proof base, Air Filter are socketed in dust cap periphery, and Air Filter is to be set in loop configuration, loop configuration
It is equipped with and the baffle plate that some circular spaces are set is provided with some through holes, dust cap, baffle plate is S type structures.
Preferably, dust preventing component is arranged in the cavity of shell and radome formation, circuit board module is arranged at shielding
In the cavity that cover is formed with base.
Preferably, fixed support is strip structure, fixing hole is provided with fixed support.
Preferably, between two adjacent screens at intervals of S type structures.
Preferably, jack includes circular port and the bar hole being connected with circular port.
Preferably, being left between two bar portions for interval curved in bar portion elasticity.
The beneficial effects of the utility model are：The utility model is provided with the fixed branch of a strip structure in fixed form
Fixed support, is first fixed on wall by frame when using, and fixation is being realized by base and support bracket fastened clamping, compared to logical
The mode that base is directly anchored on wall is crossed, is dismantled more simple；The utility model have also been devised Air Filter and dust cap, prevent
Dirt net is once filtered to dust, and the S-shaped structure design inside dust cap has carried out secondary filter to bulky grain dust, this
Sample greatly reduces the probability that dust enters interiors of products, is improved the correct alarm rate of smoke detector.
Brief description of the drawings
Fig. 1 is exploded view of the present utility model.
Fig. 2 is the support bracket fastened structural representation of the utility model.
Fig. 3 is the structural representation of the utility model base position.
Fig. 4 is the structural representation of the utility model dust cap.
In figure：1 shell, 2 dust caps, 3 Air Filters, 4 dust-proof bases, 5 radomes, 6 circuit board modules, 61 transmitting-receiving light shield groups
Part, 7 bases, 8 fixed supports, 9 plush coppers, 10 bar portions, 11 fixing holes, 12 inserted links, 13 circular ports, 14 bar holes, 15 jacks, 16 gears
Plate, 17 intervals.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As Figure 1-4, smoke detector of the present utility model includes shell 1, dust preventing component, radome 5, wiring board group
Part 6, base 7 and fixed support 8, fixed support 8 are to be provided with fixing hole 11 on strip structure, fixed support 8.Fixed support 8
On be provided with the inserted link 12 that can coordinate with the jack 15 that is correspondingly arranged on base 7, inserted link includes the bar portion of two semi-cylinder structures
10, leave between two bar portions 10 for interval curved in bar portion elasticity, two tops of bar portion 10 are provided with to fix and inserted described
Plush copper 9 in hole, jack 15 includes circular port 13 and the bar hole 14 being connected with circular port.
First fixed support 8 is fixed on wall when using, then inserted link 12 is inserted into the circular port 13 in jack 15,
Base is rotated again, inserted link is entered in bar hole and two plush coppers 9 on inserted link carry out limitation fixation.Need dismounting
When, it is only necessary to smoke detector overturn just detachable.
Dust preventing component includes dust cap 2, Air Filter 3 and dust-proof base 4, and Air Filter 3 is socketed in the periphery of dust cap 2, dust-proof
Net 3 is to be provided with to be provided with the baffle plate that some circular spaces are set on some through holes, dust cap 2 in loop configuration, loop configuration
16, baffle plate 16 is that the interval 17 between S type structures, two adjacent screens is S type structures.
Dust preventing component is arranged in the cavity of shell 1 and the formation of radome 5, and circuit board module 6 is arranged at radome 5 and bottom
In the cavity that seat 7 is formed.Radome 5 improves the antijamming capability of product circuit plate, prevents dust from entering from circuit board module again
Enter to transmitting-receiving light shield.
Utility model works principle is：Transmitting-receiving light shield component 61 is provided with circuit board module 6, light shield component bag is received and dispatched
Include electroluminescent lamp and receive light lamp, the light that electroluminescent lamp is sent under normal circumstances can be received by receipts light lamp, but if smog is entered
Sensor, the then light that electroluminescent lamp is sent can be covered by smog and cause receipts light lamp can not receive light, therefore sensor sends alarm signal
Number.
Described above is only preferred embodiment of the present utility model, is come for those skilled in the art
Say, on the premise of the utility model principle is not departed from, some improvement can also be made, it is new that these improvement also should be regarded as this practicality
The protection domain of type.
