Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and specifically relates to an atomization module and a nebulizer.

Background Art

[0002] A nebulizer is an important device for bronchial disinfection and treatment. It mainly uses a treatment method of sending aerosol particles generated from a chemical solution into the lesion site of the human body through a pipe. Since the chemical solution can directly reach the lesion site and is easy to be absorbed, the nebulizer mainly uses an atomization sheet to atomize the chemical solution. However, the pore diameter of the atomization sheet is only 0.5μm - 5μm, and the clogging problem is very likely to occur, resulting in the nebulizer not working. During maintenance, the entire atomization sheet or the entire atomization module needs to be replaced.

[0003] For example, the handheld nebulizer with the application number 2019214690369 and the medical handheld nebulizer with the application number 201207574509 need to disassemble the entire nebulizer during maintenance, replace the entire atomization module, and during the replacement, it is necessary to attach the pedestal, atomization sheet, and seal ring of the atomization module to the nebulizer body one by one to form the entire atomization module. The maintenance process of the atomization module becomes complicated, and the usage cost of the nebulizer increases.

[0009] The following is a more detailed explanation of the present invention, accompanied by drawings, and is intended as a description of the present invention, not as a limitation. This invention is an atomizing module, comprising a base 1, a flexible sleeve 2, and an atomizing sheet 3. The flexible sleeve 2 covers the edge of the atomizing sheet 3, the base 1 has a fixing hole, the flexible sleeve is fitted into the fixing hole, an electrode fixing seat 5 is provided on the outer wall of the base 1, an electrode column 4 is provided inside the electrode fixing seat 5, and the electrode column is electrically connected to the atomizing sheet.

[0010] Referring to Figure 4, the base is an annular structure with a limit ring 10 on its inner wall, the flexible sleeve is provided inside the inner hole of the base and covered by the limit ring, the electrode fixing seat is provided on the outer wall of the base, the base has two electrode column mounting holes, a wire groove is provided on the surface of the electrode fixing seat 5, the two electrode columns are mounted inside the electrode column mounting holes and connected to the atomizing sheet 3 via a wire, the wire is laid along the wire groove.

[0011] Referring to Figures 2 and 3, the flexible sleeve is made of silicone and includes a collar and a snap ring 6. The snap ring is coaxially mounted at the bottom of the collar, and an annular recessed groove 7 is provided inside the collar. The edge of the atomizing sheet is located within the recessed groove, and the operating area of ​​the atomizing sheet is located within the inner bore of the collar. This ensures that the atomizing sheet is fixed in place and allows liquid to pass through the atomizing sheet without affecting its atomizing function. The snap ring is a hollow tube located at the bottom of the collar and extending axially, with an annular groove on its side wall that fits into the limit ring. The collar is mounted in the base and positioned at the top of the limit ring. The hollow tube is compressed and deformed to pass through the inner bore of the limit ring, and then restored to engage with the limit ring, thus achieving fixation of the flexible sleeve in the base.

[0012] The aforementioned collar is provided with a wire groove that communicates with the embedded groove, and the wire of the atomizing sheet passes through the wire groove, enters the electrode fixing base, and is connected to the electrode column. The flexible sleeve is made of a medical silicone material to ensure that the flexible sleeve has sufficient elasticity and to meet the usage requirements of the nebulizer. Since the contact positions with the electrode posts are different for nebulizers of different model numbers, in order to apply this atomization module to different nebulizers, the mounting positions of the electrode posts of this nebulizer need to conform to the requirements of the contact positions of each model number of nebulizer. The following several electrode post positions will be used as examples for explanation.

[0013] Example 1 Referring to FIGS. 1 and 4, an atomization module includes a base and a flexible sleeve fitted therein. An atomization sheet is provided in the flexible sleeve. An electrode fixing seat 5 is provided on the outer wall of the base. Electrode post mounting holes provided coaxially are respectively provided on the end faces at both ends of the electrode fixing seat 5. Two electrode posts are respectively mounted in the mounting holes. The ends of the electrode posts protrude outside the electrode fixing seat and are used to contact the contacts of the nebulizer to achieve electrical conduction. A concave groove is provided at the center of the top of the electrode fixing seat. One ends of two wires are respectively connected to the two electrode posts. The two wires are laid along the wire groove. The other ends of the two wires are gathered in the concave groove and then respectively connected to the steel plate and the ceramic plate of the atomization sheet. A pin is provided on the steel plate of the atomization sheet. The pin is introduced into the concave groove through the wire groove and connected to the wire. Thereby, the problem that a gap occurs between the steel plate of the atomization sheet and the embedding groove due to the welding point can be avoided, ensuring that the steel plate and the bottom surface of the embedding groove are in sufficient contact, and the sealing performance can be improved.
