Description

Atomizing assembly and atomizer Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an atomization component and an atomizer. Background Art

[0002] A nebulizer is an important device used for bronchial disinfection and treatment. It primarily converts liquid medicine into mist particles and delivers them into the affected area of ​​the human body through a catheter. Because the liquid medicine can directly reach the affected area and is easily absorbed, the nebulizer relies primarily on atomizer plates to atomize the liquid medicine. However, the aperture of the atomizer plate is only between 0.5μm and 5μm, making it very prone to clogging. This can cause the nebulizer to stop working, requiring replacement of the atomizer plate or the entire atomizer module for maintenance.

[0003] For example, a handheld nebulizer with application number 2019214690369 and a medical handheld nebulizer with application number 2019206754509 can only be disassembled and the entire nebulizer module replaced during maintenance. During the replacement process, the base, atomizer plate and sealing ring of the atomizer module are installed one by one into the nebulizer body to form the entire atomizer module, which makes the maintenance process of the atomizer module cumbersome and increases the use cost of the nebulizer.

[0004] Summary of the Invention

[0005] In response to the problems existing in the prior art, the present invention provides an atomizer assembly and an atomizer, wherein the atomizer plate is embedded in the fixing seat through a flexible fixing sleeve, which greatly simplifies the structure of the atomizer assembly and also facilitates the disassembly, assembly and maintenance of the atomizer plate.

[0006] The present invention is achieved through the following technical solutions:

[0007] An atomizing assembly comprises a base, a flexible sleeve and an atomizing sheet;

[0008] The flexible sleeve covers the edge of the atomizer. The base is provided with a fixing hole, and the flexible sleeve is embedded in the fixing hole. The outer wall of the base is provided with an electrode fixing seat, and the electrode fixing seat is provided with an electrode column. The electrode column is electrically connected to the atomizer.

[0009] Preferably, a snap-fit ​​structure is provided in the base for fixing the flexible sleeve.

[0017] An atomizer comprises an atomizer body and an atomizing assembly installed inside the atomizer body.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] The atomizer assembly covers the edge of the atomizer plate with a flexible sleeve, so that the two form an integral structure. Then, the flexible sleeve is embedded in the base by taking advantage of its deformation characteristics, thereby achieving a stable connection between the atomizer plate and the base. At the same time, the flexible sleeve can also seal the edge of the atomizer plate. When the atomizer assembly is installed on the atomizer, the entire atomizer module can be installed on the main body of the atomizer. At the same time, the flexible sleeve also realizes the sealing of the atomizer module and the atomizer body. The atomizer module has a simple structure, reduces manufacturing costs, improves disassembly and assembly efficiency, and reduces the maintenance cost of the atomizer.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings, which are intended to explain rather than limit the present invention.

[0030] An atomizing assembly comprises a base 1, a flexible sleeve 2 and an atomizing sheet 3.

[0031] The flexible sleeve 2 is wrapped around the edge of the atomizing sheet 3. The base 1 is provided with a fixing hole, and the flexible sleeve is embedded in the fixing hole. The outer wall of the base 1 is provided with an electrode fixing seat 5. The electrode fixing seat 5 is provided with an electrode column 4, and the electrode column is electrically connected to the atomizing sheet.

[0032] Referring to Figure 4, the base is a circular ring structure, with a limit ring 10 provided on its inner wall, and the flexible sleeve is provided in the inner hole of the base and sleeved on the limit ring; the electrode fixing seat is provided on the outer wall of the base, and two electrode column mounting holes are provided on the base. A wire groove is provided on the surface of the electrode fixing seat 5, and two electrode columns are installed in the electrode column mounting holes. The two electrode columns are connected to the atomizer 3 through wires, and the wires are laid along the wire grooves.

[0033] Referring to Figures 2 and 3, the flexible sleeve is made of silicone. The flexible sleeve includes a collar and a clamping ring 6. The clamping ring is coaxially arranged at the bottom of the collar. An annular embedding groove 7 is provided on the inside of the collar. The edge of the atomizer is provided in the embedding groove. The working area of ​​the atomizer is located in the inner hole of the collar. In this way, the atomizer is fixed and the liquid can pass through the atomizer without affecting the atomization function of the atomizer. The clamping ring is a hollow tube arranged at the bottom of the collar and extending axially. The side wall of the hollow tube is provided with an annular groove, which matches the limiting ring. The collar is installed in the base and is located at the top of the limiting ring. The hollow tube is squeezed and deformed to pass through the inner hole of the limiting ring. The hollow tube recovers its deformation and the annular groove is clamped on the limiting ring to fix the flexible sleeve to the base.

[0034] The sleeve ring is provided with a wire groove which is communicated with the embedding groove. The wire of the atomizing sheet passes through the wire groove and enters the electrode fixing seat to be connected with the electrode column.

[0035] The flexible sleeve is made of medical silicone material, which ensures that the flexible sleeve has sufficient elasticity and meets the use requirements of the atomizer.

[0036] Since the contact points of the electrode columns on different atomizer models are located at different positions, in order to make the atomizer module suitable for different atomizers, the installation position of the electrode column of the atomizer needs to meet the contact position requirements of each type of atomizer. The following electrode column positions are used as examples for explanation.

The two electrode columns are respectively installed in the mounting holes, and the ends of the electrode columns extend to the outside of the electrode fixing seat for contacting with the contacts on the atomizer to achieve electrical conduction. A groove is provided at the top center of the electrode fixing seat, one end of the two wires is respectively connected to the two electrode columns, and the two wires are laid along the wire groove. The other ends of the two wires are gathered in the groove and are respectively connected to the steel sheet and ceramic sheet of the atomization sheet. Pins are provided on the steel sheet of the atomization sheet, and the pins are introduced into the groove through the electrolytic cell and connected to the wires. This can avoid the problem of gaps between the steel sheet of the atomization sheet and the embedded groove due to welding points, and ensure that the steel sheet is in full contact with the bottom surface of the embedded groove to improve the sealing performance.
