Embodiment 1

[0034] Such as Figure 1-2 As shown, in this embodiment, the housing 200 of the indoor air environment monitoring device is a cylindrical structure with two ends open, the upper opening of the housing 200 is provided with an inner flange 201, and the air outlet groove 303 is composed of the inner flange 201 and The upper baffle 306 is used to install the air outlet 302. The upper baffle 306 is overlapped with the inner flange 201 to form a sealed bottom of the air outlet groove 303. The top cover 304 is fixed with support ribs 307, and the top cover 304 is supported. The ribs 307 are placed on the upper baffle 306, so that there is a certain distance between the top cover 304 and the bottom of the air outlet groove 303, and the upper baffle 306 is detachably installed on the detection air duct, so that the top of the housing directly forms an air outlet. Groove 303; the top cover and the upper baffle are connected by screws.

[0035] The upper baffle can also be integrated wi...

Embodiment 2

[0038] Such as figure 1 , image 3As shown, in this embodiment, the housing 200 of the indoor air environment monitoring device is a cylindrical structure with two ends open, the upper opening of the housing 200 is provided with an inner flange 201, and the air outlet groove 303 is composed of the inner flange 201 and The upper baffle 306 is used to install the air outlet 302. The upper baffle 306 is overlapped with the inner flange 201 to form a sealed bottom of the air outlet groove 303. The upper baffle 306 is a flat plate structure, and the upper baffle 306 is detachable. For detecting the air duct, the top of the casing directly forms an air outlet groove 303; the upper baffle 306 is fixedly provided with support ribs 307, and the top cover 304 is placed on the upper baffle through the support ribs 307, so that the top cover 304 and the outlet There is a certain distance between the bottoms of the wind grooves 303, and the top cover and the upper baffle are connected by ...

Embodiment 3

[0041] Such as figure 1 , Figure 4 As shown, the difference from Embodiment 2 is that the upper baffle 306 is an upper plate for installing the frame of the detection air duct 301, the middle part of the upper baffle 306 is recessed downwards to form a cavity 308, and a plurality of supporting ribs 307 are arranged on On the edge of the concave cavity 308 , the support ribs 307 are arranged radially and uniformly distributed along the outer circumference of the concave cavity 308 at equal intervals.

[0042] Wherein, the supporting ribs 307 may also be arranged non-radially, and may also be non-uniformly distributed along the outer circumference of the concave cavity 308 at equal intervals.

[0043] On the one hand, the upper cover is provided with electrical components, and by setting the cavity 308, sufficient space is provided for the installation of the electrical components; space, increasing the buffer space, preventing the gas from being discharged too fast and causi...

Abstract

The invention belongs to the field of environment monitoring equipment and particularly relates to an air outlet structure of indoor air environment monitoring equipment. A detection air flue is arranged in the indoor air environment monitoring equipment, and the air outlet structure is arranged at an air outlet of the air flue; an air outlet groove communicated with the air outlet is formed in the top of a shell of the indoor air environment monitoring equipment, and a top cover is mounted at an opening in the upper end of the air outlet groove and is separated from the bottom of the groove by a certain distance; a certain interval is formed between the periphery of the top cover and the side wall of the air outlet groove to form an air outlet gap, an inner flange is arranged at an upper opening of the shell, the air outlet groove consists of the inner flange and an upper baffle, and the upper baffle is used for forming the air outlet and is lapped with the inner flange to form a sealed groove bottom. Through the arrangement of the air outlet groove, the top cover is mounted at the opening in the upper end of the air outlet groove, and the air outlet is smartly hidden under the top cover, so that the dripping of foreign matters from the top of the air outlet structure is avoided, and electric elements in the air outlet structure are effectively protected.

Description

technical field [0001] The invention belongs to the field of environmental monitoring equipment, and in particular relates to an air outlet structure of indoor air environment monitoring equipment. Background technique [0002] In recent years, the problem of air pollution has become more and more serious, especially regional air pollution. Smog affects people's travel, and fine particle pollution such as PM2.5 has attracted widespread attention from the public. The composition of outdoor pollutants is complex, resulting in indoor gas pollution from traditional formaldehyde, carbon monoxide and other harmful gases to gas-solid comprehensive pollution caused by formaldehyde, carbon monoxide and PM2.5 particles. The air quality situation in the environment is also getting more and more attention. [0003] At present, for the detection of indoor air on the market, hand-held detectors are mostly used. This type of detection equipment has the advantages of being easy to carry an...
