The atomizing device body is characterized by: a filter assembly installed at one end; the filter assembly including a protective cover rotatably connected by a hinge; a limiting groove formed on one side of the outer wall of the protective cover; a filter cover placed in the limiting groove; the filter cover surrounding the air inlet of the atomizing device body; a screw threadedly connected to one side of the filter cover; a protrusion fixedly connected to the top of the outer circumference of the atomizing device body; and an air inlet pipe provided on the top of the outer circumference of the protective cover. This invention, by setting up a filter assembly, can filter external air before it enters the atomizing device body, thereby blocking impurities in the air and preventing the accumulation of these impurities from affecting the normal operation of the equipment.

[0004] The aforementioned device has the function of blocking air impurities, but the existing device uses gas to disperse the solution to achieve atomization. Although it can achieve the effect of the solution being sprayed out with the gas, it cannot guarantee the uniformity of the atomized gas particles, which will affect the detection accuracy of the solution to be tested. At the same time, the solution inside the device will accumulate during atomization, which will affect the atomization effect of the device. Therefore, it is necessary to provide an atomization device for an aerosol generator. Utility Model Content

[0005] The purpose of this invention is to provide an atomizing device for an aerosol generator to solve the problems of existing... The device suffers from poor uniformity of atomized particles and problems with solution accumulation inside the device affecting the detection of the test solution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an atomizing device for an aerosol generator, comprising a compressed air pipe, wherein an atomizing mechanism is provided on the compressed air pipe; the atomizing mechanism comprises a first liquid hopper and a second liquid hopper, wherein a first rubber stopper is fixedly installed on the first liquid hopper, and a spray pipe is fixedly installed through the first rubber stopper; a second rubber stopper is fixedly installed on the second liquid hopper, and an air outlet pipe is fixedly installed through the second rubber stopper; a filter cap is fixedly installed at one end of the air outlet pipe.

[0007] Preferably, the middle parts of the No. 1 liquid hopper and the No. 2 liquid hopper are connected by a horizontal pipe, and one end of the compressed air pipe is at the same height as the horizontal pipe.

[0008] Preferably, one end of both the nozzle and the air outlet pipe is higher than the compressed air pipe, and one end of the nozzle is provided with an inverted trapezoidal groove.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Combination Figures 1-4 An atomizing device for an aerosol generator includes a compressed air pipe 1, and compressed air... Atomizing mechanism 2 is provided on pipe 1; atomizing mechanism 2 includes a first liquid hopper 201 and a second liquid hopper 202. A first rubber stopper 203 is fixedly installed on the first liquid hopper 201, and a spray pipe 204 is fixedly installed through the first rubber stopper 203. A second rubber stopper 205 is fixedly installed on the second liquid hopper 202, and an air outlet pipe 206 is fixedly installed through the second rubber stopper 205. A filter cap 207 is fixedly installed at one end of the air outlet pipe 206.

[0019] The middle sections of liquid hopper 201 and liquid hopper 202 are connected by a horizontal pipe, and one end of the compressed air pipe 1 is at the same height as the horizontal pipe. One end of the nozzle 204 and the air outlet pipe 206 are both higher than the compressed air pipe 1. Furthermore, one end of the nozzle 204 is provided with an inverted trapezoidal groove. Benefiting from the shape of the nozzle 204 and the positional relationship of the compressed air pipe 1, the first liquid hopper 201, the second liquid hopper 202, the nozzle 204, and the outlet pipe 206, the solution is dispersedly sprayed out by the nozzle 204, and the high-pressure gas sprayed out by the compressed air pipe 1 is sprayed from the first liquid hopper 201 into the second liquid hopper 202, so that the small particulate solution is dispersed into uniform mist particles and discharged through the outlet pipe 206. The bottom port diameter of the first liquid hopper 201 and the second liquid hopper 202 is smaller than the top port diameter, so as to prevent the atomized solution from being discharged from the bottom of the first liquid hopper 201 and the second liquid hopper 202, while the large particulate solution is discharged from the bottom of the first liquid hopper 201 and the second liquid hopper 202. The filter cap 207 is composed of a large-pore filter plate, which is used to disperse the airflow and make the atomized solution particles more uniformly dispersed.

[0020] Example 2 See Figure 5 Liquid storage mechanism 3 is provided on liquid hopper 201 and liquid hopper 202. Liquid storage mechanism 3 includes bottle cap 301, which is glued to liquid hopper 201 and liquid hopper 202. Liquid storage bottle 302 is threaded on bottle cap 301. Drain plug 303 is movably installed on the lower side of liquid storage bottle 302. Air inlet pipe 304 is fixedly installed on one side of liquid storage bottle 302. Purification plug 305 is installed at one end of air inlet pipe 304.

[0021] A gap is left between the bottom of the storage bottle 302 and the first and second liquid hoppers 201 and 202, allowing large particles of solution that have not been completely atomized to collect at the bottom of the first and second liquid hoppers 201 and flow into the bottom of the storage bottle 302. One end of the air inlet pipe 304 is at the same height as the bottom ends of the first and second liquid hoppers 201 and 202 to prevent the collected solution from clogging the air inlet pipe 304. The purification plug 305 is composed of a capillary filter plate and is snap-fitted onto the air inlet pipe 304, allowing external gas to be filtered by the purification plug 305. It enters the storage bottle 302, and achieves the effect of making the purification plug 305 removable and replaceable.

[0022] In actual operation, thanks to the shape of the nozzle 204 and the positional relationship of the compressed air pipe 1, the first liquid hopper 201, the second liquid hopper 202, the nozzle 204 and the outlet pipe 206, the solution is dispersed by the nozzle 204 and the high-pressure gas ejected by the compressed air pipe 1 is sprayed from the first liquid hopper 201 into the second liquid hopper 202, so that the small particulate solution is broken into uniform mist particles and discharged through the outlet pipe 206. Compared with traditional atomization technology, the atomization effect of this device is better and the atomized solution is more uniformly dispersed. Large particles of solution that have not been atomized are collected at the bottom of the first liquid hopper 201 and the second liquid hopper 202 and flow into the bottom of the storage bottle 302. One end of the air inlet pipe 304 is at the same height as the bottom of the first liquid hopper 201 and the second liquid hopper 202 to prevent the collected solution from clogging the air inlet pipe 304. The purification plug 305 is snap-fitted onto the air inlet pipe 304 so that the external gas is filtered by the purification plug 305 before entering the storage bottle 302, and the purification plug 305 can be removed and replaced.
