[0002] Ultrasonic nebulizer is a medical device that uses the principle of ultrasound to convert liquid medicine into tiny droplets. It directly acts on the patient's respiratory tract through these tiny droplets to achieve the purpose of treatment.

[0003] The atomization rate usually refers to the amount of droplets that a nebulizer can produce per unit time. The atomization rate directly affects the therapeutic dose of the drug.

[0045] The collecting assembly 2 is installed on the computing assembly 1. The collecting assembly 2 includes a collecting cylinder 202.

The dispersion shell 304 is fan-shaped. The lower part of the dispersion shell 304 is evenly provided with dispersion holes 3041. A gap for aerosol circulation is reserved between the dispersion holes 3041 and the collection tube 202;

[0048] refer to Figure 5 , Figure 6 During the dispersion operation, the incoming aerosol enters the dispersion housing 304 through the dispersion pipe 301, and then is ejected from the dispersion hole 3041. The fan-shaped dispersion housing 304 has space for the aerosol to circulate, ensuring that the aerosol can circulate normally.

[0049] The disassembly assembly includes a placement frame 203 and a support ring 303. The placement frame 203 is fixedly installed on the inner wall of the collection tube 202. The inner side of the support ring 303 is fixedly connected with a support bar 302. The support bar 302 is fixedly connected to the dispersion pipe 301.

[0050] refer to Figure 4 , Figure 5 The support ring 303 can be partially removed from the placement frame 203, and the placement frame 203 is used to provide support force for the support ring 303.

[0051] The gas outlet component 4 is fixedly mounted on the collecting cover 201. The gas outlet component 4 includes a gas outlet pipe 401.

[0052] refer to Figure 7 , Figure 1 The air inlet 403 is used for the air flow after absorption to enter, the conical portion 404 can increase the number of the air inlet holes 403 to facilitate the air flow to enter, and the air outlet 402 is used for the air flow to blow out.

[0053] An air intake assembly 5, which is used to connect the ultrasonic atomizer and the collection assembly 2 to each other. The air intake assembly 5 includes a vertical tube 506 rotatably installed at the center of the collection cover 201. A connecting portion 504 is provided at the lower end of the vertical tube 506. A connecting pipe 502 is fixedly connected to the upper part of the vertical tube 506. A matching insert 501 is fixedly connected to the end of the connecting pipe 502 away from the vertical tube 506. A corrugated section 503 is provided on the connecting pipe 502. The connecting portion 504 is threadedly matched with the dispersion pipe 301. A sealing portion 505 is provided on the vertical tube 506. A sealing ring 507 is provided on the inner wall of the matching insert 501. A sealing plate 5011 is rotatably connected in the matching insert 501. A sealing spring 5012 is fixedly connected inside the matching insert 501. The sealing spring 5012 is in contact with the inner side of the sealing plate 5011. A sealing cover is threadedly connected to the entry end of the matching insert 501.

[0054] refer to Figure 8 The pipe for generating water mist of the ultrasonic atomizer can be directly inserted into the matching insert 501. The sealing ring 507 is used to ensure the sealing performance of the matching insert 501 after plugging. The corrugated section 503 allows the connecting pipe 502 to be bent and stretched to a small length. The sealing part 505 is used to seal the connection between the vertical pipe 506 and the collecting cover 201. The connecting part 504 can be connected to or disassembled from the dispersion pipe 301, which is convenient for maintenance and use.

[0055] refer to Fig. 9 The sealing plate 5011 and the sealing cover are used to provide sealing performance at the mating insert 501 when not in use. When the sealing plate 5011 is not affected by the air pressure of the aerosol, the sealing plate 5011 is in a sealed state, and the sealing spring 5012 provides the sealing pressure required for sealing. When the aerosol enters from the mating insert 501, under the action of the aerosol pressure, the elastic force of the sealing spring 5012 is overcome, and the sealing plate 5011 is pushed to open, ensuring that the aerosol can enter normally for detection and use. Among them, the shape of the part where the sealing spring 5012 contacts the sealing plate 5011 can be an arc shape, which is convenient for ensuring the uniformity of the elastic pressure. The sealing cover can provide the outermost seal and protection, and the sealing cover part is not drawn in the specification diagram.

[0056] The water absorbing member 6 is installed in the collecting tube 202 and is used to absorb the water mist generated by the ultrasonic atomizer.

[0057] refer to Figure 2 The water-absorbing member 6 can be made of a common material that can absorb water mist, such as sponge, a mixture of sodium polyacrylate and cotton, and wood fiber. Sponge, a mixture of sodium polyacrylate and cotton, and wood fiber all have good water absorption and can absorb the liquid medicine components in the water mist.

[0058] Working principle: When in use, unscrew the collecting cover 201, first place the unused water absorbing member 6 on the dispersion pipe 301, then tighten the collecting cover 201, and then directly insert the pipe for generating water mist of the ultrasonic atomizer into the matching insert 501. The sealing ring 507 is used to ensure the sealing performance of the matching insert 501 after plugging. The water mist generated by the ultrasonic atomizer enters the dispersion housing 304 through the connecting pipe 502, the vertical pipe 506, and the dispersion pipe 301, and then is ejected from the dispersion hole 3041. The ejected airflow is downward. The airflow is arranged to be dispersed by the conical block 204 first and then flow upward. In this way, the velocity of the airflow becomes slower and the flow distance becomes longer. The water mist in the airflow is then absorbed by the water absorbing member 6. The airflow after absorption enters from the air inlet 403 and is then discharged from the air outlet 402. The calculation of the atomization rate is, for example: the working time of the ultrasonic atomizer is selected to be five minutes, the weight value before water absorption is M1, and the weight value after water absorption is M2. Then the atomization rate is (M2-M1) / 5min, and the value of the atomization rate can be calculated.

[0059] Embodiment 2: The difference from Embodiment 1 is that: a corrugated section 503 is provided on the connecting pipe 502, the connecting portion 504 is threadedly matched with the dispersed pipe 301, a sealing portion 505 is provided on the vertical pipe 506, a sealing ring 507 is provided on the inner wall of the matching insert 501, and an outer spring piece group 5013 and an inner spring piece group 5014 which are circular in shape as a whole are provided in sequence from the outside to the inside of the matching insert 501;

[0060] refer to Fig.10 The outer spring fragment group 5013 and the inner spring fragment group 5014 can provide a sealing effect for both the inner and outer layers. Both the outer spring fragment group 5013 and the inner spring fragment group 5014 are composed of an upper and lower part, which can be opened after being subjected to force. When the outer spring fragment group 5013 is inserted into the nozzle of the ultrasonic nebulizer, it can provide a certain clamping force to the nozzle. After the nozzle of the ultrasonic nebulizer is pulled out, the aerosol can be prevented from being brought out. In addition, a certain distance is reserved between the two outer spring fragment groups 5013 and the inner spring fragment group 5014, which can provide double-layer isolation for the aerosol, thereby improving the detection accuracy.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
