Technical Field

[0001] This utility model belongs to the field of safety protection and relates to environmental monitoring technology, specifically a miniature harmful gas protection device. Background Technology

[0002] The interior environment of special vehicles directly affects the working condition of personnel. When the external environment is polluted, polluted air will enter the cabin, harming the physical and mental health of personnel and thus affecting their work. Most vehicles are now equipped with protective devices, which contain filters and absorbers with corresponding airflow. Therefore, these devices are relatively large and take up a lot of space, so they can only be installed outside the cabin. Summary of the Invention

[0003] The purpose of this invention is to provide a miniature hazardous gas protection device that is small in size and lightweight, and can be installed both inside and outside the vehicle cabin. Despite its small size, it provides long-lasting protection against a variety of hazardous gases. When installed inside the vehicle cabin, the miniature hazardous gas protection device can purify odorous gases generated within the cabin; when installed outside the cabin, it can purify polluted air from outside and then deliver it into the cabin, thus achieving two purposes with one device. Because the device occupies little space, users can equip themselves with an appropriate number of devices according to their needs.

[0004] This utility model is achieved using the following technical solution:

[0005] A miniature hazardous gas protection device includes a fan, an air inlet pipe, an air inlet plate, a baffle, an adsorption unit, a filter unit, a housing, an upper fixing base, an air outlet sealing flange, an air outlet sealing gasket, an air outlet plate, an air outlet pipe, a lower fixing base, and mounting lugs.

[0006] The housing is arranged in a V-shape with filter adsorption units, dividing the housing into an air inlet area and an air outlet area. Each filter adsorption unit consists of a filter unit and an adsorption unit, with the filter unit located on the air inlet side and the adsorption unit located on the air outlet side. The air inlet area of ​​the housing is provided with an air inlet pipe, and a fan is installed in the air inlet pipe. The air outlet area of ​​the housing is provided with an air outlet pipe.

[0007] More preferably, the air inlet pipe is welded to the air inlet plate at one end of the housing.

[0008] More preferably, the air outlet pipe is welded to the air outlet plate at the other end of the housing.

[0009] More preferably, two upper fixing seats are symmetrically welded to the upper part of the other end of the housing, and two lower fixing seats are symmetrically welded to the lower part. The upper fixing seats and the lower fixing seats are sequentially fixed with an air outlet sealing flange, an air outlet sealing gasket, and an air outlet plate.

[0010] A further preferred embodiment includes an air outlet sealing gasket between the air outlet plate and the air outlet sealing flange.

[0011] In a further preferred embodiment, baffles are symmetrically welded inside the housing, and the filter adsorption unit is fixed to the baffles by potting adhesive.

[0012] More preferably, the housing is provided with mounting lugs symmetrically on both sides.

[0013] In use, firstly, two upper fixing seats are welded to the two sides of the upper part of one end of the housing, and two lower fixing seats are welded to the two sides of the lower part of the other end of the housing. Two lifting lugs are then welded and installed on the left and right sides of each side of the housing. The air inlet pipe is welded to the air inlet plate, and then the entire assembly is welded to one end of the housing. The adsorption unit and the filter unit are then combined to form a filter adsorption unit, with one end fixed against the baffle and sealed with glue, forming a "V" shape inside the housing. The fan is then bolted to the inside of the air inlet pipe.

[0014] Next, install the air outlet panel. First, weld the air outlet pipe to the air outlet panel, and then use fasteners to fix the air outlet panel, air outlet sealing gasket, and air outlet sealing flange to the upper and lower fixed seats in sequence.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention integrates a fan, a filter unit, and an adsorption unit in a small space, achieving two purposes with one device.

[0017] 2. In this utility model, the filter adsorption units are arranged in a "V" shape inside the housing. The "V" shape arrangement makes the airflow smooth and uniform in the device, and increases the filtration area, resulting in better protection and extended protection time.

[0018] This utility model features a reasonable design, integrating a fan, filter unit, and adsorption unit within a small space, achieving two purposes with one device. Due to its small footprint, it can be used modularly, allowing users to equip it with the appropriate number of units according to their needs, facilitating application and promotion.

Detailed Implementation

[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] A miniature hazardous gas protection device, such as Figure 1 As shown, it includes a fan 1, an air inlet pipe 2, an air inlet plate 3, a baffle 4, an adsorption unit 5, a filter unit 6, a housing 7, an upper fixed base 8, an air outlet sealing flange 9, an air outlet sealing gasket 10, an air outlet plate 11, an air outlet pipe 12, a lower fixed base 13, and mounting lugs 14, etc.

[0025] like Figure 1 As shown, the housing 7 has a V-shaped arrangement of filter adsorption units, dividing the housing 7 into an air inlet area 701 and an air outlet area 702. Each filter adsorption unit consists of a filter unit 6 and an adsorption unit 5, with the filter unit 6 located on the air inlet side and the adsorption unit 5 located on the air outlet side. The air inlet area 701 of the housing 7 is provided with an air inlet pipe 2, and a fan 1 is installed inside the air inlet pipe 2. The air outlet area 702 of the housing 7 is provided with an air outlet pipe 12. The air inlet pipe 2 is welded to the air inlet plate 3 at one end of the housing 7. The air outlet pipe 12 is welded to the air outlet plate 11 at the other end of the housing 7. Two upper fixing seats 8 are symmetrically welded to the upper part of the other end of the housing 7, and two lower fixing seats 13 are symmetrically welded to the lower part. An air outlet sealing flange 9 and an air outlet plate 11 are fixedly installed on the upper fixing seats 8 and the lower fixing seats 13 respectively. An air outlet sealing gasket 10 is provided between the air outlet plate 11 and the air outlet sealing flange 9. Baffles 4 are symmetrically welded inside the housing 7, and the filter adsorption units are fixed to the baffles 4 by potting glue. The housing 7 has symmetrical mounting lugs 14 on both sides.

[0026] like Figure 2 As shown, the fan 1 is installed inside the air inlet pipe 2, which cleverly utilizes the space without occupying the space of the device casing, thus achieving a small overall space occupation of the device.

[0027] like Figure 3 As shown, the upper sides of the outer shell of the miniature hazardous gas protection device are designed with rounded arcs.

[0028] During assembly, firstly, weld two upper fixing seats 8 to the two sides of the upper part of one end of the housing 7, and weld two lower fixing seats 13 to the two sides of the lower part of the other end of the housing 7. Then, symmetrically weld two mounting lugs 14 on the left and right sides of each side of the housing 7.

[0029] Weld the air inlet pipe 2 onto the air inlet plate 3, then weld the whole assembly onto one end of the housing 7, and fix the fan 1 inside the welded air inlet pipe 2 with bolts.

[0030] Then, the adsorption unit 5 and the filter unit 6 are combined to form a filter adsorption unit. One end of the filter adsorption unit is fixed close to the baffle 4 and sealed with glue, forming a "V" shape inside the housing 7.

[0031] Next, install the air outlet plate. First, weld the air outlet pipe 12 onto the air outlet plate 11. Then, use fasteners to fix the air outlet plate 11, the air outlet sealing gasket 10, and the air outlet sealing flange 9 onto the upper fixing seat 8 and the lower fixing seat 13 in sequence to form a stable and sealed air outlet channel.

[0032] During operation, polluted external air is drawn into the air intake area 701 of the housing 7 by the fan 1 through the air intake pipe 2. First, it passes through two V-shaped filter units 6 to initially filter dust particles and aerosols. Then, it passes through two V-shaped adsorption units 5 to purify toxic and harmful gases. The purified air flows out of the adsorption units 5 and into the air outlet area 702. The clean air from the two adsorption units 5 converges at the air outlet pipe 12, from which it is discharged. Each miniature hazardous gas protection device contains two filter units 6 and two adsorption units 5, both arranged in a V-shape within the housing 7. This V-shaped arrangement not only makes the airflow smoother and more uniform but also increases the filtration area, resulting in better protection and extended protection time.

[0033] The miniature harmful gas protection device described in this utility model integrates a filtration unit, an adsorption unit, and a fan into one unit, achieving small size and light weight. It realizes two functions in one device, occupies little space, and can be used in a modular manner, thus having good practical application value.
