Description

Technical Field

[0001] This utility model belongs to the field of aerosol detection and analysis technology, and specifically relates to an aerosol analyzer. Background Technology

[0002] Aerosols are dispersion systems formed by tiny solid or liquid particles suspended in a gas. These particles typically range in diameter from 0.01 to 100 micrometers and can remain suspended in the air for extended periods. Aerosol analyzers are devices specifically designed to measure and analyze particulate matter (i.e., aerosols) suspended in the air. These instruments can provide information on a variety of physical and chemical properties of aerosols.

[0003] Existing aerosol analyzers deliver aerosols to the analysis site via an external pump. A particle size analyzer within the analyzer detects the particle size distribution of the aerosol particles and displays the detected particle sizes on a control panel, thus enabling particle size analysis. However, in practical use, due to varying particle concentrations, the pump's delivery force needs to be increased to deliver more concentrated aerosols. This results in a faster aerosol delivery rate, reducing the time available for the particle size analyzer to detect the particle size distribution and affecting the accuracy of the aerosol analysis. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an aerosol analyzer that allows for stable adjustment of the amount that can pass through per unit time during use, thereby enabling free and stable adjustment of the aerosol delivery rate to facilitate stable delivery of aerosols at a suitable rate.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an aerosol analyzer includes a detection platform, an installation box inside the detection platform, an air inlet pipe on the upper side of the installation box, an air outlet pipe on the lower side of the installation box, a detection tube between the air inlet pipe and the air outlet pipe, a U-shaped adjusting seat inside the air inlet pipe, a symmetrically distributed through-hole on the U-shaped adjusting seat, and symmetrically distributed installation tubes on the outer side of the air inlet pipe. Each installation tube has a sliding column inside, and a conical adjusting block is provided at the end of each sliding column near the through-hole. The conical adjusting blocks are respectively fitted with adjacent through-holes. A driving mechanism is also provided on the installation tube to control the movement of the conical adjusting blocks. Multiple support feet are provided on the lower surface of the detection platform, and rubber pads are adhered and fixed to the lower surface of each support foot.

[0006] As a further improvement of this utility model, the drive mechanism includes a drive tube mounted on the mounting tube, and an adjusting screw is rotatably mounted in the middle of the drive tube. The adjusting screw is threadedly connected to the adjacent sliding column. A motor is mounted on the outside of the drive tube, and the output shaft of the motor is fixed to the adjacent adjusting screw by a coupling.

[0007] As a further improvement of this utility model, a particle size spectrometer module is provided on the detection tube.

[0008] As a further improvement of this utility model, a controller is provided on the detection platform, and the particle size spectrometer module and the motor are all electrically connected to the controller.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the operation of the motor is adjusted according to the needs of detection and analysis, and the distance between the conical adjusting block and the through-hole is adjusted, thereby adjusting the size of the gap between the conical adjusting block and the through-hole.

[0011] Secondly, by steadily adjusting the size of the gap between the conical adjusting block and the orifice, the amount that can pass through per unit time can be adjusted, and thus the aerosol delivery rate can be freely and stably adjusted as needed.

[0012] Third, the aerosol is transported by an external delivery pump, and the delivery rate is further adjusted by a motor to ensure that the aerosol is transported at a suitable rate. Then, the particle size distribution of the particles is measured by a particle size analyzer module through laser scattering and electromobility, thereby realizing the detection and analysis of the aerosol.

[0013] Fourth, the rubber pads on the upper surface of the support legs can effectively increase the friction between the support legs and the ground, thereby effectively preventing the testing platform from easily moving during the testing process. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the device includes a testing platform 101, an installation box 103 inside the testing platform 101, an air inlet pipe 104 on the upper side of the installation box 103, an air outlet pipe 105 on the lower side of the installation box 103, a testing pipe 106 between the air inlet pipe 104 and the air outlet pipe 105, a U-shaped adjusting seat 201 inside the air inlet pipe 104, symmetrically distributed openings on the U-shaped adjusting seat 201, and symmetrically distributed installation pipes 202 on the outer side of the air inlet pipe 104. A sliding column 203 is slidably installed inside each installation pipe 202, and a conical adjusting block 204 is provided at the end of each sliding column 203 near the opening. The conical adjusting block 204 is installed in conjunction with the adjacent opening.

[0022] like Figure 3 , 4 As shown, a drive mechanism is also provided on the mounting tube 202. The drive mechanism is used to control the movement of the conical adjusting block 204. The drive mechanism includes a drive tube 205 provided on the mounting tube 202. An adjusting screw 206 is rotatably provided in the middle of the drive tube 205. The adjusting screw 206 is threadedly connected to the adjacent sliding column 203. A motor 207 is provided on the outside of the drive tube 205. The output shaft of the motor 207 is fixed to the adjacent adjusting screw 206 by a coupling.

[0023] like Figure 2 , 4 As shown, a particle size spectrometer module 107 is installed on the detection tube 106.

[0024] like Figure 1 , 4 As shown, a controller 301 is installed on the detection platform 101, and the particle size spectrometer module 107 and the motor 207 are both electrically connected to the controller 301.

[0025] During use, the operation of motor 207 is adjusted according to the needs of detection and analysis. This causes the output shaft of motor 207 to drive the adjusting screw 206 connected to it to rotate. By adjusting the thread relationship between the adjusting screw 206 and the sliding column 203, the sliding column 203 slides between itself and the mounting tube 202. This causes the sliding column 203 to move the conical adjusting block 204 closer to or further away from the opening on the U-shaped adjusting seat 201, thus adjusting the distance between the conical adjusting block 204 and the opening. This allows for the adjustment of the size of the gap between the conical adjusting block 204 and the opening. By stably adjusting the size of the gap between the conical adjusting block 204 and the opening, the amount that can pass through per unit time can be adjusted, thereby allowing for free and stable adjustment of the aerosol delivery rate as needed.

[0026] An external delivery pump is connected to the inlet pipe 104 via a connecting pipe, and a collection pipe is connected to the outlet pipe 105. The particle size analyzer module 107 is then controlled by the controller 301 to operate. The aerosol is transported by the external delivery pump, and the delivery rate is further adjusted by the motor 207 to ensure that the aerosol is transported at a suitable rate. The particle size analyzer module 107 then measures the particle size distribution of the aerosol by laser scattering and electromobility to achieve the detection and analysis of the aerosol.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the lower surface of the testing platform 101 is provided with multiple support legs 102, and rubber pads are glued and fixed to the lower surface of each support leg 102. During use, the rubber pads on the lower surface of the support legs 102 can effectively increase the friction between the support legs 102 and the ground, thereby effectively preventing the testing platform 101 from easily moving during the testing process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
