Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] Reference Figure 1 Combination Figure 2 The image shows an inhalation-type droplet spectrometer, comprising a housing 1 and a camera 2, a lens 3, a laser assembly 4, and a fan 5 disposed within the housing 1. Its distinctive features are as follows: Figure 2 As shown, camera 2 and lens 3 are mounted together on one side of housing 1. Figure 2 The image is shown above the viewer's line of sight on one side, while the laser assembly 3 is mounted on the other side of the housing 1 (i.e., Figure 2 The laser beam is positioned on the side below the viewer's line of sight (as shown) and opposite to lens 3 to project onto lens 3. This configuration ensures that the laser beam is aligned with the particle and the lens, maximizing the area of ​​particle illumination. It avoids the adverse effects of traditional offset settings, such as small illumination area and light reflection, and helps to obtain accurate three-dimensional particle data.

[0019] To obtain accurate and reliable particle data, this embodiment employs a fan 5 installed in the housing to draw air from the area to be measured into the housing. Specifically, the lens 3 and laser assembly 4 are respectively installed... Figure 2 The heating duct 7 shown on opposite sides provides constant heating to the particles entering the housing, thereby heating them through the fan and pipe connection assembly 6 (including...). Figure 4 The connecting shaft 24, elbow 25, and connecting sleeve 26, which are sequentially connected to the rear end of the heating air duct 7, are then pressed tightly onto the connecting sleeve 26 and the pipe at the air outlet end of the fan 5 by the clamping ring 27 (the air outlet end of the fan 5 is fixed in the mounting hole of the base plate 1 through the fan fixing cover 28) and the heating air duct 7 (the air outlet of the fan 5 is connected to the heating air duct 7 through the pipe connecting assembly 6) and the heating air duct 7 achieve the stabilization and heating of the intake air particles, realize the stability of the detected particles, thereby improving the accuracy and reliability of the detection data and avoiding the adverse effects of low temperature.

[0020] Depend on Figure 2 It can also be seen that a reflector 8 is provided at the objective lens end of the camera 2 to reflect the incident light beam from the lens 3 at a 90° angle to the objective lens end of the camera 2. An optical transceiver 22 is also provided inside the housing 1 to realize remote data transmission and facilitate real-time and synchronous acquisition of detection data.

[0021] To further ensure the stability of the gas entering the casing and to ensure the accuracy and reliability of the detection data, this embodiment... Figure 3The heating air duct 7 is provided with an air duct extension pipe 9 at the inlet thereof, and a heat preservation sleeve 10 is further arranged on the air duct extension pipe 9. A tubular electric heating film 11 is arranged at the port of the air duct extension pipe 9 outside the shell 1 and is wrapped in the heat preservation sleeve 10. The tubular electric heating film 11 (i.e. the electric heating film is required to be attached to the inner wall of the installation object in a shape, so that balanced heating effect can be obtained, and the stability of the airflow can be ensured) further realizes stable heating of the air in the section, thereby prolonging the stability of the temperature of the air particles to be detected, and especially ensuring the stability of the particles in the region between the laser group and the lens.

[0022] Finally, it should be noted that the heating air duct 7 involved in the embodiment can be composed of an electric heating film, which is fixed by the bracket 23.

[0023] In order to conveniently obtain the temperature of the particles to be detected and timely adjust the temperature, the embodiment is provided with Figure 4 The heating air duct 7 is provided with a first temperature sensor 12. Since the temperature of the particles in the region near the laser group and the lens is mainly ensured, the first temperature sensor 12 is fixed in the region (referred to as a detection region) between the lens 3 and the laser group 4 in the embodiment, i.e. the first temperature sensor 12 is arranged on the heating air duct 7 in the detection region.

[0024] Since the airflow at the inlet of the pipeline will affect the airflow in the detection region, the air duct extension pipe 9 is additionally arranged, and the heat preservation sleeve 10 and the tubular electric heating film 11 are additionally arranged. In order to reduce the adverse effect on the temperature of the particles in the detection region, the second temperature sensor 13 is arranged at the front end of the air duct extension pipe 9 in the embodiment, i.e. the second temperature sensor 13 is arranged at the intersection of the front end (i.e. the inlet) of the air duct extension pipe 9 and the tubular electric heating film 11. As long as the temperature of the particles near the intersection meets the requirement of accurate and stable detection, a heat preservation screen can be formed to ensure the stability of the temperature of the particles in the detection region.

[0025] By Figure 4 It can be further found that the fan 5 is fixed on the rear side panel 37 of the shell 1 in the embodiment; the heating air duct 7 is arranged at the upper portion of the shell 1, i.e. close to the top plate, and the front end thereof extends from the air duct port 16 on the front panel 15 of the shell 1; the rear end of the air duct extension pipe 9 is inserted into the front end of the heating air duct 7 and is fixed by the first pressing ring 17 wrapped outside the air duct extension pipe 9; the first pressing ring 17 is threadedly connected with the air duct port 16 (the pipeline installation member arranged on the front panel 15 of the shell). Such layout can effectively increase the length of the heating air duct, which is helpful for stable detection of the particles, especially can increase the heating area, which is beneficial for rapid heating and maintaining the constant temperature.

[0026] In conclusion Figure 3As can be seen, the fan drive 20 and the fan driver 20 are installed inside the housing 1. Figure 5 The waterproof power supply 21 is shown; the fan driver 20 is fixed between the waterproof power supply 21 and the heating air duct 7, and is fixed to the housing by a bracket. The waterproof power supply 21 is mounted on the base plate 14, which helps to improve the stability of the entire device. Figure 6 As can be seen, the rear panel 37 of the housing 1 is equipped with an optical fiber power combination plug 32, a waterproof power connector 33, a power indicator 34, a power switch 35, and a fan noise reduction pipe 36 (installed on...). Figure 2 The air outlet pipe 38 of the fan shown) and the external temperature sensor 39.

[0027] Depend on Figure 5 As can be seen, a waterproof cable connector 18 is installed on the insulation sleeve 10. Its inner end is electrically connected to the tubular electric heating film 11, and its outer end is electrically connected to the aviation plug connector 19 mounted on the housing 1 via a cable. This enables power supply to the tubular electric heating film 11, i.e., the aviation plug connector 19 is electrically connected to the waterproof power supply 21. (This is achieved through...) Figure 1 It can be seen that each of the four feet of the base plate 14 is equipped with a fixing block 31.

[0028] The airborne large particle cloud and fog measuring instrument is mounted on a drone or other flight control system aircraft. After flying to the area to be measured, it monitors air particles and stores the data. Then, the data is copied or transmitted remotely via an optical transceiver to a dedicated computer, where specialized software is used to calculate the number, concentration, and size of particles in the sampled airspace.
