Combustible gas probe 100 provided by the embodiment of the utility model, by the way that the cavity inside shell 105 is arranged in
120, form a fixed chamber, it is easier to perceive the variation of ambient atmos concentration.It is opened by be connected to cavity 120 first
Mouthfuls 115 and second opening 133, merging for 120 inside of cavity and external environment is enhanced, inside and outside gas concentration is made to tend to unification.
By the combustible gas sensor 125 being arranged in cavity 120, make the variation to this inside and outside gaseous environment more rapid
Detection, can also preferably detect the variation of current combustable gas concentration, make corresponding safety measure for personnel and provide more
More time has ensured people's security of the lives and property.
As shown in figure 5, combustible gas probe 100 further includes mounting plate 150, mounting plate 150 detachably connects with shell 105
It connects.So, combustible gas probe 100 can be fixed on the wall by mounting plate 150, and dismounting is more flexible, conveniently be made
With.
Further, as shown in Figure 3 and Figure 4, shell 105 further includes the second panel 140 opposite with first panel 110,
Concave part 143 and slide groove portion 145 are provided in second panel 140, be respectively arranged on mounting plate 150 with concave part 143 and
The corresponding lug boss 153 of slide groove portion 145 and pawl socket part 155.
It should be noted that first, the utility model embodiment is not particularly limited the shape of concave part 143, example
, concave part 143 can be set to rectangular recess or semi-circular recesses, as long as object can be made to be caught in.
Second, slide groove portion 145 has merging area and insertion area, and merging area is connected with insertion area, facilitates putting for external object
Enter and clamping.In order to guarantee the stability of connection, slide groove portion 145 is set as multiple, exemplary, can be set to three, makes phase
Connection between mutually is more stable.
Third, lug boss 153 has certain elasticity, convex when pawl socket part 155 is placed into the merging area of slide groove portion 145
Portion 153 is played to abut with second panel 140.And it is parallel between lug boss 153 and concave part 143, it slides into and is embedded in pawl socket part 155
Qu Shi, lug boss 153 are embedded into concave part 143 when restoring elastic deformation, make between mounting plate 150 and second panel 140
Connection is more firm, reduces the risk of landing.
4th, the end of pawl socket part 155 is more narrower than root, so, when pawl socket part 155 is put into merging area, more holds
Easily pawl socket part 155 is advanced in insertion area, the process for keeping installation fixed is more convenient.
5th, it constitutes between the first panel 110 and second panel 140 of shell 105 to be detachably connected, facilitates inside zero
The installation of component is combined.I.e. shell 105 is non-integral molding structure, the convenient installation and removal to combustible gas probe 100,
Keep the maintenance work in later period lighter, improves the efficiency of maintenance.
As shown in figure 5, the first connector 117 is additionally provided in shell 105, first connector 117 and controller (Fig. 5
In be not drawn into) electrical connection.
Specifically, the position that do not interfere with mounting plate 150 is arranged in the first connector 117, mounting plate 150 is avoided to block the
A connector 117 influences the use of user.So, user-friendly external output function, it is exemplary, number can be passed through
It is connect according to the first connector of bundle of lines 117 with the solenoid valve of combustion gas, when combustible gas probe 100 detects gas leakage, control
The solenoid valve of combustion gas processed is closed.
Further, it being concavely provided with groove 147 in second panel 140, the first connector 117 is arranged in 147 bottom of groove,
And 117 notch 2mm or more of the top away from groove 147 of the first connector.
Specifically, the first connector 117 is arranged in 147 bottom of groove, so, connect when by connection cables and first
After connecing the connection of device 117, facilitates and combustible gas probe 100 is articulated on wall.In addition, in 100 wall of combustible gas probe
It can also directly be connected with connection cables when extension, eliminate the trouble won.Meanwhile reducing connection cables bending angle
The problems such as insertion is difficult caused by excessive and is easily damaged connection cables.
As shown in figure 3, being additionally provided with battery compartment 113 in shell 105,113 side wall of battery compartment is provided with opening direction
Second connector 119 of battery compartment 113.
Specifically, being used for placing battery in battery compartment 113, normal service life is up to 5 years, more stable using battery
Reliably, the trouble being necessarily mounted at socket is eliminated, can be installed according to the actual situation in place.Decrease because
External power supply power-off causes sensor to stop working, and then causes the risk of security risk.
In addition, the second connector 119 is arranged inside shell 105, the indetectable position of user, and the second connector
119 staff for being only responsible for maintenance read the relevant operations such as alarm history by ad hoc fashion, after general user's connection
It cannot use, prevent user's mistake from using and operating.
So, stability when combustible gas probe 100 uses is improved, region carries out hidden being of little use
Design, also makes overall structure more compact, enhances user experience.
As shown in Figure 1, combustible gas probe 100 further includes buzzer 160, buzzer 160 is electrically connected with the controller.
Specifically, buzzer 160 carries out buzzing response when combustible gas sensor 125 detects imflammable gas, mention
The related personnel that wakes up carries out emergency operation, avoids dangerous generation.Likewise, combustible gas probe 100 further includes alarm light,
Booster action is played to the alarm response of buzzer 160, can preferably help user to find specific position, reduce at problem
The reason investigation time.Alternatively, it is also possible to be set as audio alert, the various concentration that can be detected according to combustible gas sensor 125
Value, carries out corresponding warning note, can also the information such as verbal announcement failure and battery capacity.
Shell 105 and mounting plate 150 are all made of non-flammable resin material.So, combustible gas probe can be made
100 shape is more beautiful, and antiageing effect is good, is unlikely to deform, and has certain elasticity, mounting plate 150 and shell 105
Between be easy installing and dismounting.
As shown in Figure 1, combustible gas probe 100 further includes the alarm shutdown switch being arranged in first panel 110
170, stop for controlling alarm.
So, after situation of clearing, the alarm shutdown switch 170 on combustible gas probe 100 can be pressed,
The sense of urgency can be eliminated, makes one to cool it, meanwhile, it is more energy saving, extend the service life of combustible gas probe 100.
As shown in Figure 1, being provided with air inlet grid 180 between the first opening 115 and cavity 120.
So, it can protect the combustible gas sensor 125 in cavity 120, reduce combustible gas sensor 125
The directly exposed probability for being touched damage by the external world in cavity 120.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
