Detailed description of the invention
For further illustrating each embodiment, this utility model is provided with accompanying drawing.These accompanying drawings are in this utility model discloses
The part held, it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated former to the running explaining embodiment
Reason.Coordinating with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantage of type.Assembly in figure is not necessarily to scale, and similar element numbers is conventionally used to indicate similar assembly.
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
In the present embodiment, gas sensor box shell uses cylindrical structure.
Refering to shown in Fig. 1 to Fig. 5, the gas sensor box of this utility model one preferred embodiment, including: lower circuit board 1,
Shell 2, gas sensor 3 and upper circuit board 4.Wherein, the inner chamber of shell upper 21 and outer casing underpart 22 is the most through, outward
The diameter on shell top 21 is more than the diameter of outer casing underpart 22, and air inlet 23 is positioned at the bottom surface of shell upper 21 by outer casing underpart end face
On region outside covering.
Gas is entered in gas sensor box shell upper 21 space by air inlet 23, detects for gas sensor.This
Gas sensor box is vertically placed when using, and air inlet 23 has shell upper 21 to block, it is to avoid the entrance of rainwater.
Refering to Fig. 3, if gas sensor 3 is positioned on circuit board 4, in order to allow extraneous gas can arrive gas sensor
Around 3, arranging airway 24 in the shell upper 21 of shell 2, air inlet 23 is positioned at the lower end of airway 24, and air inlet 23
And it is that air-flow is through between airway 24.Extraneous gas enters in airway 24 by air inlet 23, along airway 24 from
Airway 24 upper end enters shell upper 21 near the position of gas sensor 3.
Additionally, in order to prevent mosquito from entering in shell 2, arrange network structure on the top of airway 24, at airway 24
Bottom the effect that network structure also can reach same is set.
Refering to Fig. 1 and Fig. 2, lower circuit board 1 has conducting slip ring 11, vent 12 and screw hole 13, vent 12
