[0002] The nebulizer is used to atomize the test solution. The nebulizer is an important part of the atomization system, and its performance has a significant impact on the precision of the measurement and chemical interference. Therefore, the nebulizer is required to have stable spray, small and uniform droplets, and high atomization efficiency.

[0003] After searching, the patent with application number CN202122079361.8 discloses a sealing structure of an atomizer with good atomization effect and good suction experience, comprising: a shell (101), one end of which is provided with an opening, and an oil filling hole and an air hole are provided on the opposite side of the opening of the shell (101); a sealing silicone (105), which is installed in the shell (101) and is used to seal the oil storage chamber of the shell (101); an atomization core (107), one end of which is installed on the sealing silicone (105), and the other end of which is fixed in the air hole of the shell (101) to form an atomization channel; an oil filling silicone (104), one end face of which is set as a plane, and the other end face is provided with at least one convex column, and the oil filling silicone (104) cooperates with the oil filling hole of the shell (101) through the convex column; an inner concave (corresponding to 104a1) that is non-airflow connected to the oil storage chamber (101a) is formed in any convex column.

[0004] The current nebulizer host and the nebulizer pipe are sealed to prevent the drug solution from leaking out. However, the existing sealed connection structure between the nebulizer host and the nebulizer pipe mostly uses a layer of sealing ring to achieve sealing, and the sealing effect is not good. In addition, the connection method between the host and the nebulizer pipe is complicated, and the connection process is cumbersome and troublesome, which makes it inconvenient for users to use. Therefore, we need to propose a sealing structure for the nebulizer. Utility Model Content
