Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generators, in particular to an aerosol generator. Background Art

[0002] An aerosol generator, also known as a nebulizer or aerosol sprayer, is a device that can generate tiny droplets or solid particles. These droplets or particles can be suspended in the air to form an aerosol. Aerosol generators can be used to prepare standard substances, calibration gases, and simulants of environmental particulate matter in environmental monitoring, such as preparing standard simulants of PM2.5, PM10 and other particles to detect the concentration and composition of particulate matter in the air.

[0003] The existing Chinese patent with announcement number CN216321424U discloses an aerosol generator, including a generator body, a liquid storage tank is fixedly installed on the left side of the inside of the generator body, a heating plate is fixedly installed on the lower left side of the liquid storage tank, a protective cover is fixedly installed on the left side of the top of the generator body, a motor is fixedly installed inside the protective cover, a stirring rod is movably installed on the motor through a coupling, rolling wheels are fixedly installed on all sides of the bottom of the generator body, a control panel is fixedly installed on the right side of the rear front end of the generator body, and a scale plate is fixedly installed on the lower left side of the front end of the generator body.

[0004] Although the above scheme can drive the stirring rod to mix the medicine liquid, the aerosol generator only rotates on a single axis when stirring, resulting in insufficient stirring effect. In addition, the activated carbon adsorption plate is fixed inside the filter cover when the aerosol generator performs gas filtering, which makes its replacement more troublesome and easily affects the filtering effect. Therefore, it does not meet the existing needs. In this regard, we propose an aerosol generator. Utility Model Content

[0005] The utility model aims to provide an aerosol generator to solve the problems in the above background technology that the aerosol generator has insufficient stirring effect on the drug solution and it is inconvenient to replace the activated carbon adsorption plate, which easily affects the normal filtering effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aerosol generator, comprising a main body, a stirring chamber is provided inside the main body, a nozzle is provided on one side of the upper end of the stirring chamber, and one end of the nozzle extends to the outside of the stirring chamber, a nozzle is provided on one end of the nozzle outside the stirring chamber, an air compressor is provided on one side of the stirring chamber, a filter chamber is provided on one side of the air compressor, the air compressor is connected to the stirring chamber and the filter chamber through a connecting pipe, and an air inlet pipe is provided on one side of the filter chamber;

[0007] It also includes a first transmission chamber, which is opened above the stirring chamber, two first rotating shafts are arranged inside the first transmission chamber, one end of each of the first rotating shafts penetrates and extends into the stirring chamber, and each of the first rotating shafts is rotatably connected to the first transmission chamber, and second transmission chambers are opened on the upper and lower sides of both sides of the stirring chamber, a third rotating shaft is arranged inside the second transmission chamber, and one end of each of the third rotating shafts extends into the stirring chamber, and second rotating shafts are rotatably arranged on both sides of the upper end of the first transmission chamber, and one end of each of the second rotating shafts penetrates and extends into the second transmission chamber;

[0008] It also includes a rotating door, which is arranged on one side of the front end of the main body, and the rotating door is connected to the main body through a hinge. Three equidistantly distributed activated carbon filter plates are arranged inside the filter chamber, and the activated carbon filter plates are all fitted with the protrusions at the rear end of the rotating door.

[0009] Preferably, a motor is disposed at the upper end of the first transmission cavity, and an output end of the motor is driven to one of the first rotating shafts via a coupling.

[0010] Preferably, the first rotating shaft and the outer wall of one end inside the first transmission cavity are both provided with transmission gears, and the transmission gears are meshingly connected with each other.

[0011] Preferably, one of the first rotating shafts and one end of the two second rotating shafts located inside the first transmission cavity are connected by a transmission belt.

[0012] Preferably, a rubber pad is adhesively fixed to the rear end of the rotating door.

[0013] Preferably, the outer wall of the first rotating shaft at one end inside the stirring chamber is welded with three groups of equally spaced first stirring blades, and each group of first stirring blades is provided with four equally spaced first stirring blades in a ring shape, and the end of the third rotating shaft located inside the stirring chamber is installed with second stirring blades.

[0014] Preferably, the outer wall of the second rotating shaft at one end located inside the second transmission cavity and the end of the third rotating shaft located inside the second transmission cavity are both provided with bevel gears, and the bevel gears are meshingly connected.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model is provided with second rotating shafts for rotation on both sides inside the first transmission chamber. When the motor is started for stirring, the motor will drive the first rotating shaft to rotate, so that the first stirring blade can rotate laterally. At this time, the two second rotating shafts can be rotated synchronously under the transmission of the transmission belt. The second rotating shaft can rotate the third rotating shaft through the bevel gear, and the third rotating shaft will drive the second stirring blade to rotate synchronously, so that the synchronous rotation of the first stirring blade and the second stirring blade can be realized. Since the first stirring blade and the second stirring blade rotate in the horizontal and vertical directions respectively, they can cover different areas and levels in the stirring chamber, so that the medicine liquid can be mixed more evenly and the stirring can be more sufficient.

[0017] The utility model provides a transmission gear on the outer wall of the first rotating shaft at one end inside the first transmission chamber. When the motor is started to rotate the first rotating shaft, the two first rotating shafts can be rotated synchronously under the meshing transmission of the transmission gear, thereby generating two stirring vortices. Compared with a single stirring vortex, a larger area can be covered, so that all parts of the medicine liquid can participate in the mixing process more quickly. Since the two vortices work at the same time, the medicine liquids between them will collide and convect with each other to form a more complex mixed flow. This flow pattern can accelerate the mutual diffusion and penetration between the medicine liquid molecules, thereby improving the mixing speed and increasing the work efficiency.

[0018] The utility model has a filter chamber on one side of the main body, and a rotating door is arranged in front of the filter chamber. In daily use, the protrusion behind the rotating door can be used to support the activated carbon filter plate, so that the activated carbon filter plate can be conveniently fixed. The activated carbon filter plate can be released by simply opening the rotating door, and the activated carbon filter plate can be conveniently replaced, so as to ensure long-term filtering effect.
