Referring to fig. 1-12, the present invention provides a technical solution: a smoke alarm system comprises a mounting base 1, wherein two waist-shaped holes 5 are symmetrically formed in the mounting base 1, screws can penetrate through the waist-shaped holes 5 from the lower side and then can be driven into the wall to complete mounting of the mounting base 1, an upper half shell 9 is movably clamped on the lower side surface of the mounting base 1, the mounting base 1 can be mounted on the wall firstly during mounting, then the upper half shell 9 and the mounting base 1 are clamped, the device can be mounted conveniently, the upper half shell 9 is movably clamped with a lower half shell 14 through clamping plates 13 fixedly connected with the upper half shell 9 through two side surfaces, corresponding clamping openings 15 are formed in the lower half shell 14, the clamping plates 13 are made of hard plastic plates with certain elasticity, the lower side surface of the lower half shell 14 is connected with a bottom plate 19 through a plurality of connecting blocks 18, and the bottom plate 19 can be used for protecting an induction probe 24;

open the inside of upper half shell 9 has first mounting groove 16, install battery compartment 20 (of course battery compartment 20 also can change into power module, through electric wire and external power switch-on) and alarm 21 in the inslot of first mounting groove 16 respectively, battery compartment 20 and alarm 21 all install the inside at first mounting groove 16 through the bolt, the dry battery can be installed to the inside of battery compartment 20, be used for providing the energy for this device, alarm 21 can send out the police dispatch newspaper sound, remind people to take place the conflagration, and first mounting groove 16 is connected with control module 23 through two erection columns 22 that are fixedly connected with on its upside cell wall, control module 23's both sides face fixedly connected with mounting panel 25, be equipped with the screw hole on the mounting panel 25, can link together control module 23 and mounting column 22 through the bolt, install inductive probe 24 on the control module 23, control module 23, Electrically connect between inductive probe 24, battery compartment 20, alarm 21 and the air discharge fan 29, control module 23's internally mounted has single chip module and PLC controller, inductive probe 24's lower extreme passes through to open some through-hole 32 on half lower shell 14 and extends to the outside of half lower shell 14, and inductive probe 24's lower extreme extends to the outside of half lower shell 14 can be better and external air contact each other to can be better detect, it has through-hole 26 to open on bottom plate 19, electric motor 28 is installed through the dead lever 27 that fixed connection has on its inside wall in through-hole 26, and electric motor 28 passes through the bolt and installs on dead lever 27, fixedly connected with air discharge fan 29 on electric motor 28's the output shaft, air discharge fan 29 passes through the key and is in the same place with electric motor 28's output shaft, electric motor 28 passes through electric wire and the inside socket 30 interconnect of fixed connection in second mounting groove 17, the second mounting groove 17 is formed in the lower half shell 14, the socket 30 is movably clamped with the plug 31, the plug 31 is connected with the battery bin 20 through an electric wire, the plug 31 is inserted into the socket 30, the electric motor 28 can be connected with dry batteries in the battery bin 20, and therefore the electric motor 28 is electrified;

when the sensing probe 24 senses smoke, a signal is sent to the single chip microcomputer module, the single chip microcomputer module controls the electric motor 28 to rotate through the PLC after receiving the signal, the electric motor 28 drives air around the sensing probe 24 to rapidly flow through the exhaust fan 29, when the sensing probe 24 continuously detects that smoke reaches a threshold value (the size of a specific threshold value is related to the type and the installation requirement of a sensor of the sensing probe 24), the alarm 21 starts to give an alarm, otherwise, the alarm 21 does not give an alarm (the duration time when the smoke reaches the threshold value can be adjusted through the single chip microcomputer module, for example, three seconds, the specific time is determined by the type and the installation requirement of the sensor of the sensing probe 24 and is unrelated to the structure of the application);

inductive probe 24, single chip module, PLC controller and alarm are prior art characteristic, so the utility model discloses do not do the perusal, for example inductive probe 24 can adopt MQ-2 model, and single chip module can adopt AT89S52 model, and the PLC controller can adopt the PLC controller of Siemens series.

Particularly, two snap rings 7 of mounting base 1's downside fixedly connected with, and two snap rings 7 are central symmetry and arrange, it has two dead slots 10 to open on half upper casing 9, and the position of two dead slots 10 is corresponding with two snap rings 7, and equal fixedly connected with fixed plate 11 on the both sides cell wall of dead slot 10 one end, and the shape of snap ring 7 cross section is T shape, and the one end looks adaptation of the groove width of

dead slot

10 and 7 width broad of snap ring, inserts the inside of dead slot 10 with snap ring 7 earlier during the installation, then rotates half upper casing 9 and makes

fixed plate

11 and 7 mutual joint of snap ring can accomplish half upper casing 9's installation.

Specifically, the downside of snap ring 7 is opened has location mouth 8, the tank bottom fixedly connected with of dead slot 10 corresponds circular arch 12, can make the joint between snap ring 7 and the fixed plate 11 inseparabler.

Particularly, the side fixedly connected with double faced adhesive tape 2 on mounting base 1, and be connected with protective layer 3 on the double faced adhesive tape 2, can want to glue mounting base 1 on the position that needs the installation through double faced adhesive tape 2, can easy to assemble, and protective layer 3's setting can be when not using that double faced adhesive tape 2 can not glue other things.

Specifically, one end of the protective layer 3 is fixedly connected with a stripping sheet 4 protruding outwards, and the protective layer 3 can be better uncovered by the stripping sheet 4.

Particularly, the downside of mounting base 1 just is located 5 upper circumferences of waist type hole and opens there is countersunk head groove 6, and countersunk head groove 6's setting can give the nut on the screw of fixed mounting base 1 and give way the position, is that the nut keeps one level with the downside of mounting base 1, conveniently installs half shell 9.

The working principle is as follows: when in installation, the protective layer 3 is firstly torn off, then the installation base 1 is stuck on the position needing to be installed, and then the installation base 1 is installed by using screws, then the upper half shell 9 and the mounting base 1 are mounted, when the inductive probe 24 detects smoke and transmits data to the singlechip, and when the smoke reaches the threshold value, the single chip microcomputer enables the PLC to enable the electric motor 28 to be started, the exhaust fan 29 starts to work to enable air around the induction probe 24 to flow rapidly, and at the moment, if the induction probe 24 senses that the smoke reaches the threshold value all the time and lasts for a certain time (for example, three seconds), the alarm 21 gives an alarm to remind people of fire, so that serious life and property loss caused by untimely fire finding can be avoided, if the inductive probe cannot continuously detect that the threshold value is exceeded, the alarm 21 is not triggered, and loss caused by false alarm is prevented.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
