As a further description of the above technical solution:

it is a plurality of lower bleeder vent includes the few pore body of multiunit and porous body, the arc setting that all is the slope with bottom edges and corners department all around the sensor housing body bottom, few pore body evenly distributed is in sensor housing body bottom edges and corners department, porous body evenly distributed is around sensor housing body bottom.

As a further description of the above technical solution:

the upper air holes are arranged in a honeycomb shape, and the lower air holes are arranged in a strip shape.

As a further description of the above technical solution:

the plurality of the oblique strip holes are arranged at equal intervals.

As a further description of the above technical solution:

the height of the two oblique strip holes below the circular hole is smaller than that of the rest oblique strip holes.

The utility model has the following beneficial effects:

1. compared with the prior art, this air inlet structure of empty gas detection surveys sensor, through the sensor shell body, go up the bleeder vent, bleeder vent down, mutually support between the few hole body and the porous body, through setting up bleeder vent down, and the bleeder vent is comparatively even arranges in the bottom week side of sensor shell body down, make the air in the external world change get into in the sensor shell body, and the entering of air is comparatively even, so that each detects uses sensor work, the detection error that minimizes, it also more does benefit to the inside heat dissipation of sensor shell body to go up seting up of bleeder vent and bleeder vent down simultaneously.

2. Compared with the prior art, this air detection sensor's inlet port structure through mutually supporting between sensor shell body, oblique strip hole and the circular port, sets up independent oblique strip hole and circular port again with the position that corresponds the sensor and be close to on the sensor shell body, can further accelerate the entering of air, and the pertinence is stronger for the detection effect that corresponds the sensor is more ideal.
