Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings air quality detecting device 100 according to an embodiment of the present invention is described.
As depicted in figs. 1 and 2, air quality detecting device 100 according to an embodiment of the present invention, comprising: shell 1 and be used for
Detect the sensor module 2 of air quality.
As depicted in figs. 1 and 2, air inlet 13 and air outlet 14 are formed on shell 1, air inlet 13 and air outlet 14 not phase
To setting, sensor module 2 is located in shell 1.
Wherein, air inlet 13 and air outlet 14 are located at the not ipsilateral of shell 1, and air inlet 13 and air outlet 14 are not set relatively
It sets, it is to be understood that air inlet 13 and air outlet 14 be not on the same side wall of shell 1, air inlet 13 and air outlet
14 are not located in the opposite two side walls of shell 1 yet.Thus, it is possible to slow down flowing velocity of the air-flow in shell 1, consequently facilitating
The induction and detection of sensor module 2, and then the accuracy of testing result can be promoted.
In the related technology, air inlet and air outlet are located on the same side wall, and air-flow is easy to produce when flowing in shell
Vortex, influences the accuracy of testing result, while dust in air-flow or particulate matter are easy to influence air-flow in shell internal deposition
The smoothness of flowing.And in the present invention, air inlet 13 and air outlet 14 are not on the same side wall of shell 1, thus
Vortex can be generated in shell 1 to avoid air-flow, so that the accuracy of detection structure gets a promotion.At the same time it can also avoid gas
Dust or particulate matter in stream are easy to deposit in shell 1, are conducive to the smoothness for promoting air-flow flowing.
Other in the related technology, air inlet and air outlet are located in the opposite two side walls of shell, and air-flow is in shell
In vivo when flowing, the flow trace of air-flow is straight line, and the flowing velocity of air-flow is relatively large, the intracorporal sensor module of shell
It can not adequately be contacted with air-flow, cause the accuracy of testing result lower.And in the present invention, due to air inlet 13 and outlet air
Mouth 14 is not opposite, and during moving to air outlet 14 from air inlet 13, the direction of air-flow flowing can deflect air-flow, makes
The flowing velocity for obtaining air-flow will appear reduction, and thus sensor module 2 can come into full contact with air-flow, consequently facilitating sensor group
The induction and detection of part 2, and then the accuracy of testing result can be promoted.
In some embodiments of the invention, as depicted in figs. 1 and 2, the cross section of shell 1 is quadrangle, air inlet 13
It is respectively formed in the adjacent two side walls of shell 1 with air outlet 14.Thus, it is possible to simplify the complexity of 1 structure of shell, drop
The manufacture difficulty of low shell 1 promotes the production efficiency of shell 1, reduces the production cost of shell 1.For example, reality shown in Fig. 1
It applies in example, shell 1 includes left side wall, right side wall, front side wall and rear wall (front, rear, left and right as shown in Figure 1).In shell 1
Circumferential direction on, left side wall, front side wall, right side wall and rear wall head and the tail be sequentially connected.Wherein, air inlet is formed on left side wall
Mouth 13, the rear wall adjacent with left side wall are equipped with air outlet 14.
It should be noted that in the description of the present invention, it is to be understood that, term "front", "rear", "left", "right" etc.
The orientation or positional relationship of instruction is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of the description present invention and letter
Change description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation construct and
Operation, therefore be not considered as limiting the invention.
Air quality detecting device 100 according to an embodiment of the present invention, by being equipped with air inlet 13 and outlet air on shell 1
Mouth 14, and air inlet 13 and air outlet 14 be not opposite, during air-flow is flowed from air inlet 13 towards air outlet 14, air-flow stream
Dynamic direction can deflect, so that the flowing velocity of air-flow will appear reduction, consequently facilitating the induction and inspection of sensor module 2
It surveys, and then the accuracy of testing result can be promoted.

16, multiple being provided at circumferentially spaced along circuit board 21 of locating piece 16, each locating piece 16 includes being connected with each other and at an angle to each other
Interconnecting piece 161 and compressed part 162, interconnecting piece 161 are connected with the inner wall of shell 1, and compressed part 162 is connected with interconnecting piece 161, compress
Portion 162 is pressed on the second surface of circuit board 21.
It is understood that by the way that at least one sensor is arranged on the second surface of circuit board 21, from shell 1 into
Air port 13 enters the air-flow in shell 1 when flowing through sensor, and sensor can detecte out corresponding substance to be detected in gas
(for example, PM2.5, PM10, CO2、SO2Deng) concentration or gas physical state (for example, temperature, humidity etc.).
By being arranged multiple locating pieces 16 on the inner wall of shell 1, multiple locating pieces 16 to circuit board 21 have positioning and
The effect of limit can be subjected to displacement in the Process circuitry plate 21 of work to avoid sensor module 2, thereby may be ensured that sensor
The reliability that component 2 works, while increasing the accuracy of testing result.It should be noted that in the description of the present invention, it is " more
It is a " it is meant that two or more.
In addition, locating piece 16 includes being connected with each other and interconnecting piece 161 and compressed part 162 at an angle to each other.Not only may be used as a result,
To simplify the complexity of 16 structure of locating piece, the manufacturing cost of locating piece 16 is reduced, while can also guarantee circuit board 21 and shell
The bonding strength of body 1.
Specifically, sensor can be set there are two types of, three kinds, four kinds or more kinds of.For example, in Fig. 2 and shown in Fig. 7
In embodiment, it is PM2.5 sensor 22, CO respectively that there are four types of sensors for setting on the second surface of circuit board 212Sensor
23, Temperature Humidity Sensor 24 and formaldehyde sensor 25, can be detected respectively by the sensor PM2.5 concentration in air,
CO2Concentration, temperature humidity and concentration of formaldehyde.
It should be noted that including inlet and outlet in PM2.5 sensor 22, exit is also for PM2.5 sensor 22
It is provided with fan.
