Description

Technical Field

[0001] This utility model relates to the field of air detection, and specifically discloses a portable air detection device. Background Technology

[0002] Air quality monitoring equipment is an instrument used to detect the composition and quality of air. It mainly uses different types of sensors to detect different objects. For example, optical sensors are usually used to detect particulate matter, measuring the concentration of particulate matter through principles such as laser scattering. Electrochemical sensors are used to detect harmful gases such as formaldehyde, determining the gas concentration based on the current generated by the chemical reaction of the gas on the electrode. Then, the data detected by the sensor is transmitted to a microprocessor for processing, calculating the values ​​of various parameters. This data can then be wirelessly transmitted to devices such as mobile phones and computers for viewing and analysis.

[0003] For example, the utility model patent CN202123187761.7 discloses a portable intelligent air negative oxygen ion detection device. This solution facilitates the maintenance and repair of the equipment inside the box by setting up a protective door and door handle. Through the use of the air inlet channel, exhaust fan, filter sponge, air tank, detector body and battery, it can detect negative ions in the air and has the function of filtering dust and flying insects. It is easy to carry and can be used in different places. However, when general air detection equipment is used, it usually detects the floating gas in the general environment. If it is necessary to detect the gas in a certain pipeline, the detection device mentioned in the above patent requires manual assistance to hold when detecting the gas in the pipeline. When the gas is transported through the pipeline, the sealing may not be sufficient, which may affect the accuracy of the gas detection in the pipeline. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a portable air detection device to solve the technical problem that when it is necessary to detect the gas in a certain pipeline, manual assistance is required to hold the device and the gas is transported through the pipeline, and the sealing may be insufficient, which may affect the accuracy of the gas detection in the pipeline.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a portable housing assembly, wherein an air detection component for detecting air quality is installed inside the portable housing assembly;

[0006] The portable housing assembly includes a housing with a dust cover. A pair of symmetrically distributed support frames are fixedly connected to the bottom of the housing, and a carrying handle is fixedly connected to the top. An adjusting ring, in conjunction with an arc-shaped groove, moves a connecting column. The connecting column rotates due to the influence of a limiting ring and an inclined groove, which in turn causes the clamping blades to rotate, opening and closing. When gas detection is required in the pipeline, the clamping blades are opened, the pipeline is placed at the center of the circumference between the clamping blades, and then the clamping blades are closed, clamping the blades against the outer wall of the pipeline. This eliminates the need for manual pipe handling, making it more convenient and faster to use, and also provides a degree of sealing, improving the accuracy of gas detection.

[0007] Furthermore, the air detection component includes a limiting ring, which is fixedly connected to the housing. An adjusting ring is provided on the limiting ring, and several sets of clamping blades are provided between the adjusting ring and the limiting ring. The several sets of clamping blades are arranged in a ring. A connecting post is provided on the clamping blade, and the clamping blade is fan-shaped. The two ends of the connecting post are slidably connected to the adjusting ring and the limiting ring, respectively.

[0008] Furthermore, a connecting ring is fixedly connected to the adjusting ring, and the connecting ring is rotatably connected to the portable housing assembly. A worm gear is fixedly connected to the connecting ring. The position of the worm gear is defined by the connecting ring, and the worm gear is connected to the adjusting ring.

[0009] Furthermore, a motor is fixedly connected to the portable housing assembly, and a worm gear is fixedly connected to the output end of the motor via a coupling. The worm gear is rotatably connected to the portable housing assembly, and the worm gear meshes with a worm wheel. The motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel, through a connecting ring, drives an adjusting ring to rotate, thus adjusting the opening and closing degree of the clamping blades and enabling the clamping of pipes of different sizes.

[0010] Furthermore, the gas detection sensor is fixed in position by connecting the housing and the limiting ring and fixing the position of the fixing bracket. The gas detection sensor can detect the gas delivered by the pipeline, and the exhaust fan can draw in air. When detecting the gas in the atmospheric environment, the exhaust fan is turned on so that the gas can pass through the gas detection sensor. The gas detection sensor detects the air in the atmospheric environment and can flexibly switch between detecting the air in the atmospheric environment and detecting the gas in the pipeline without changing the equipment, making it more convenient to use.

[0011] Furthermore, the dust cover is fitted over the housing and the exhaust fan, and the dust cover is compatible with the housing and the exhaust fan. The dust cover prevents dust from entering and affecting the detection accuracy of the gas detection sensor.

[0012] The working principle and beneficial effects of this solution are as follows:

[0013] In use, the adjusting ring and the arc groove work together to move the connecting column. The connecting column rotates under the influence of the limiting ring and the inclined groove, which in turn drives the clamping blades to rotate, causing the clamping blades to open and close. When it is necessary to detect the gas in the pipeline, the clamping blades are opened, the pipeline is placed at the center of the circumference between the clamping blades, and then the clamping blades are closed, so that the clamping blades are clamped on the outer wall of the pipeline. There is no need for manual handling of the pipeline, making it more convenient and faster to use. It also provides a certain degree of sealing and improves the accuracy of gas detection.

[0014] When detecting gases in the atmospheric environment, the exhaust fan is turned on, allowing the gas to pass through the gas detection sensor. The gas detection sensor detects the air in the atmospheric environment and can flexibly switch between detecting atmospheric air and pipeline gases without changing equipment, making it more convenient to use.

[0015] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0023] Example

[0024] like Figures 1 to 5 As shown, a portable air detection device is disclosed, including a portable housing assembly 1.

The front end of the limiting ring 201 has multiple arc-shaped grooves that are adapted to the connecting post 204, and the arc-shaped grooves are slidably connected to the connecting post 204. The adjusting ring 202, in conjunction with the arc-shaped groove, drives the connecting column 204 to move. The connecting column 204 rotates under the influence of the limiting ring 201 and the inclined groove, which in turn drives the clamping blade 203 to rotate, causing the clamping blade 203 to open and close. When it is necessary to detect the gas in the pipeline, the clamping blade 203 is opened, the pipeline is placed at the circumference center between the clamping blades 203, and then the clamping blade 203 is closed, so that the clamping blade 203 is clamped on the outer wall of the pipeline. There is no need for manual handling of the pipeline, making it more convenient and faster to use, and it also provides a certain degree of sealing, improving the accuracy of gas detection.

[0025] A connecting ring 205 is fixedly connected to the rear end of the adjusting ring 202. The connecting ring 205 is located inside the portable housing assembly 1 and is rotatably connected to the portable housing assembly 1. A worm gear 206 is fixedly connected to the rear end of the connecting ring 205. The connecting ring 205 limits the position of the worm gear 206 and connects the worm gear 206 to the adjusting ring 202; for example... Figure 4 As shown.

[0026] The air detection component 2 also includes a motor 207, which is fixedly installed inside the portable housing component 1 and located behind the adjusting ring 202. A worm gear 208 is fixedly connected to the output end of the motor 207. The worm gear 208 is rotatably connected to the inner wall of the portable housing component 1, and meshes with a worm wheel 206. The motor 207 drives the worm gear 208 to rotate, which in turn drives the worm wheel 206 to rotate. The worm wheel 206, through the connecting ring 205, drives the adjusting ring 202 to rotate, thus adjusting the opening and closing degree of the clamping blade 203, allowing for clamping of pipes of different sizes. Figure 4 As shown.

[0027] A housing 209 is fixedly connected to the front end of the limiting ring 201. A fixing frame 210 is fixedly connected inside the housing 209. A gas detection sensor 211 is fixedly connected to the rear end of the fixing frame 210, located inside the housing 209. An exhaust fan 212 is fixedly connected to the front end of the housing 209.

It can flexibly switch between atmospheric air detection and pipeline gas detection without changing equipment, making it more convenient to use. Figure 4 and Figure 5 As shown.

[0028] The portable housing assembly 1 includes a housing 101, which is located outside the limiting ring 201, worm gear 206, motor 207, and worm 208. The housing 101 is fixedly connected to the motor 207 and the limiting ring 201, and rotatably connected to the connecting ring 205 and the worm 208. The housing 101 fixes the position of the motor 207, and the motor 207 drives the worm 208 to rotate; for example... Figure 3 As shown.

[0029] A dust cover 104 is fixedly connected to the front end of the housing 101. The dust cover 104 is fitted over the housing 209 and the exhaust fan 212, and is compatible with both. The dust cover 104 prevents dust from entering and affecting the detection accuracy of the gas detection sensor 211. Figure 3 and Figure 4 As shown.

[0030] A pair of symmetrically distributed support frames 102 are fixedly connected to the bottom end of the housing 101, and a carrying handle 103 is fixedly connected to the top end of the housing 101. The support frames 102 support the entire device, and the carrying handle 103 makes it easy for the user to hold and carry the entire device; Figure 3 As shown.

[0031] The clamping blade 203 is fan-shaped. The fan-shaped clamping blade 203 serves a sealing function during the clamping process of the pipe; for example... Figure 4 As shown.

[0032] In practice

[0033] In use, carry the device to the location where air needs to be detected. Easily move the device using the handle 103. Place the device stably on the ground using the support frame. Start the motor 104. The output of the motor 104 drives the worm gear to rotate. The worm gear meshes with the worm wheel, causing the worm wheel to rotate. The worm wheel drives the adjusting ring to rotate via the connecting ring. When the adjusting ring rotates, its front side engages with the limiting ring 203, causing the connecting column to move. The connecting column rotates due to the inclined groove at the rear end of the limiting ring 203, which in turn drives the clamping blades to rotate, opening them. Place the pipe at the circumference center between the multiple clamping blades. Then, start the motor 104 again, causing the adjusting ring to rotate in the opposite direction, closing the clamping blades. The fan-shaped clamping blades clamp the outer wall of the pipe, providing a certain degree of sealing and improving the accuracy of gas detection inside the pipe. Gas enters through the pipe, passes through the casing, and then enters the gas detection sensor for detection. Without installing the pipe, atmospheric gases can be detected directly. Turning on the exhaust fan will draw surrounding air into the device, and the gas detection sensor will detect the atmospheric gases.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
