Detailed Description

Exemplary embodiments that embody features and advantages of the present utility model will be described in detail in the following description. It will be understood that the utility model is capable of various modifications in various embodiments, all without departing from the scope of the utility model, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the utility model.

As shown in fig. 1-4, a sensor 10 includes: the upper case 11, one surface of which is provided with a first ventilation window 111, a plurality of first baffles 112 are arranged in the first ventilation window 111, and a height difference exists between two adjacent first baffles 112; the lower case 12, one side of which is provided with one or more second ventilation windows 121, a second baffle 122 is provided in the second ventilation windows 121, and a height difference exists between the second baffle 122 and the second ventilation windows 121; a sensing assembly interposed between the upper case 11 and the lower case 12.

The difference in height between the two adjacent first baffles 112 is understood to mean that there is no gap between the two adjacent first baffles 112 in the horizontal direction, but there is a gap between two sides of the first baffles 112 in the vertical direction, when air blows from the front of the upper shell 11, the air is forced to change the flow path by the crotch of the first baffles 112, and only enters the sensor 10 along the transverse or oblique gap between the two first baffles 112, so that the air must contact the first baffles 112 before entering the sensor 10, and when the air contacts the first baffles 112, the moisture in the air is mostly condensed on the first baffles 112. And also plays a role in dust prevention.

The difference in height between the second baffle 122 and the second ventilation window 121 may be understood that the second baffle 122 may block air entering the second ventilation window 121 from the front, and force the air to enter from a gap between the second baffle 122 and the second ventilation window 121 after changing the flow direction, thereby functioning as the first ventilation window 111 and the first baffle 112. And also plays a role in dust prevention.

Wherein one face of the sensing assembly faces the first louver 111 and the other face faces the second louver 121. That is, the sensing assembly is located between the first ventilation window 111 and the second ventilation window 121, improving detection sensitivity.

The first baffle 112 is disposed obliquely, wherein a lower side of the first baffle 112 faces an outside of the upper case 11, and an upper side thereof faces an inside of the upper case 11.

The first baffle 112 plays a role of preventing condensation of moisture in the sensor 10, mainly, the moisture condenses on the first baffle 112, and after condensation, the moisture drops into the first ventilation window 111 due to the fact that the lower side of the first baffle 112 faces to the outside.

In one embodiment, as shown in fig. 5-6, a gas detection system is provided, including a sensor 10 as described above, and further including a controller 20, the controller 20 including: a housing 21; the display screen 22 is arranged on the surface of the shell 21; a control board 23, the control board 23 is disposed in the housing 21, and is connected to the sensor 10 through a cable, for reading data of the sensor 10 in real time and displaying the data on the display screen 22.

The beneficial effects of the utility model are as follows from the above embodiments:

in the first ventilation window 111 of the sensor 10, a shutter-like structure is provided, which can ensure good ventilation performance of the sensor 10 and play a good role in waterproofing, and most of water vapor passing through the ventilation window can be condensed into water drops to be hung on the shutter structure, so that the role in waterproofing and ventilating the sensor 10 assembly is finally achieved. .
