Into connection.
As shown in Fig. 2 it illustrates the decomposition texture schematic diagram of the second embodiment of the technical program.With first embodiment
Compare, second embodiment has following difference.Connecting detection device 30 also includes photo-conduction cell 33, photo-conduction cell
33 are arranged between light source emitter 31 and optical receiver 32.In a second embodiment, photo-conduction cell 33 is speculum, is such as schemed
Shown in 2, the speculum is arranged in mounting seat 10, and the reflecting surface and the horizontal plane residing for mounting seat 10 of the speculum
Between it is at an angle set, it is and correspondingly that the corresponding setting angle between light source emitter 31, optical receiver 32 is mutual
Between debug and coordinate, and light source emitter 31 and optical receiver 32 are installed on clamshell 20, and optical receiver 32 is launched with light source
It is arranged at intervals between device 31.When mounting seat 10 is connected in place with clamshell 20, photo-conduction cell 33 is by the institute of light source emitter 31
The light of transmitting be sent to optical receiver 32 and so that the control alarm of control chip 200 stops sending prompting alarm.Second implements
Remaining structure of example is identical with first embodiment, will not be repeated here.
As shown in figure 3, it illustrates the decomposition texture schematic diagram of the 3rd embodiment of the technical program.With second embodiment
Compare, 3rd embodiment has following difference.Photo-conduction cell 33 in 3rd embodiment is total reflection prism, and
The total reflection prism is preferably that prism-shaped total reflection prism (can certainly select such as pentagonal prism formula total reflection prism, six
Prism total reflection prism, etc.), the total reflection prism is arranged in mounting seat 10, now, and light source emitter 31 is arranged on
On clamshell 20, and optical receiver 32 is arranged on clamshell 20, and is arranged at intervals between optical receiver 32 and light source emitter 31,
So that optical receiver 32 can receive the light through being launched by light source emitter 31 of reflecting of total reflection prism, (certainly, light connects
Receiving device 32 can also be arranged in mounting seat 10, and only need to correspondingly adjust total reflection prism goes out light path so that light source is launched
The light that device 31 is sent can reach optical receiver 32 after total reflection prism outgoing).Remaining structure of 3rd embodiment with
Second embodiment is identical, will not be repeated here.
According to another aspect of the present invention, the technical program provides a kind of installation detection method of smoke detector.Should
Detection method is installed to comprise the following steps:
Mounting seat 10 is fixedly mounted on wall, now, mounting seat 10 is separated with clamshell 20, and alarm is sent out
Go out indicating alarm (smoke detector of the technical program is energized using independent current source);
Clamshell 20 is connected (the smoke sensing device 100 of the technical program, alarm, control in place with mounting seat 10
The installation in installing space in clamshell 20 of the corresponding building block of chip 200 and connecting detection device 30, these groups
It can be integrally connected into part with clamshell 20 relative to mounting seat 10 and the part in mounting seat 10
Detection means 30 is separated, and only need to correctly be connected clamshell 20 with mounting seat 10, you can connect corresponding circuit connecting node
Connect completion);
Wherein, detect whether mounting seat 10 is connected in place with clamshell 20 by connecting detection device 30, work as connecting detection
Device 30 detects mounting seat 10 and the annexation of clamshell 20 reaches predetermined link position alarm device stopping prompting alarm.
Specifically, (the company in i.e. foregoing smoke detector when for being installed using foregoing smoke detector
Connecing detection means 30 at least includes light source emitter 31 and optical receiver 32), the installation detection method is further comprising the steps of:When
During the light that the light source emitter 31 that the optical receiver 32 of connecting detection device 30 receives connecting detection device 30 is launched, lead to
Cross the control chip 200 that is electrically connected with optical receiver 32 and detect the light intensity for receiving light, when the light intensity of received light reach it is predetermined
During range of light intensity, then the control of control chip 200 alarm stops prompting alarm.Connecting detection device 30 is being utilized to installation situation
During being detected, during clamshell 20 is connected with mounting seat 10, it is understood that there may be clamshell 20 and mounting seat 10
Between connection status be in and will connect in place but the actual state not being fully connected in place, and now clamshell 20 is with installing
Self-locking state is between base 10, now, the part light that light source emitter 31 is launched can be equally transmitted to
Optical receiver 32, but the luminous intensity that now optical receiver 32 can be received is than connecting the light intensity received when in place
It is low, also with regard to optical receiver 32 receive light intensity and not up to start control chip 200 control alarm stop point out alarm light
Strong lower limit.At this moment need with mounting seat 10 to separate clamshell 20 again to be reinstalled, it is known that connection is in place.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Any modifications, equivalent substitutions and improvements made within principle etc., should be included in the scope of the protection.
