The present invention relates to a nebulizer and a cartridge structure of the nebulizer, and more particularly to an atomizer having a particular cartridge structure.

Atomization methods are mainly used for the treatment of respiratory diseases. Such a method can be accomplished by the use of a nebulizer, wherein the particles sprayed by the nebulizer are droplets of about 3-5 μm. For example, liquid drugs can be delivered to the bronchus and lungs for treatment. Such a process breathes aerosolized particles from the liquid drug into the mouth and nose to the bronchus, which then causes the particles to spread to the entire alveoli, thereby allowing the liquid drug to be sufficiently absorbed by the body. This mode is preferred over oral administration. Currently, misting schemes that sprayers generally employ for the operating mechanism of such sprayers include pneumatic misting, ultrasonic misting, or electronic aerosol techniques (eg, piezoelectric nozzle methods). As shown in FIG. 1, a liquid drug receiving cartridge structure 1 for use with a conventional nebulizer includes an accommodation space 11, a bottom 12, a side 14 and an opening 13. The bottom 12 is arranged at the bottom of the receiving space 11, the side portion 14 is connected in the vertical direction to the bottom, the opening 13 is adjacent to the bottom 12 of the side portion 14 Is placed in position. The opening 13 is an outlet for liquid drug. When the opening 13 is in a position adjacent the bottom 12, the liquid drug may be supplied to the opening 13 by the receiving space 11.

Although the residue of the liquid drug can be reduced through the opening 13 adjacent to the bottom, such residue reduction will be limited by the overall structure of the receiving space 11. Thus, some of the liquid drug will remain at the bottom of the receiving space 11 as waste liquid drug.

In order to overcome the above-mentioned disadvantages, the inventors of the present invention have conducted intensive research and experimentation based on years of experience in related fields, and finally developed the atomizer and its cartridge structure as a method or concept that can overcome the above problems. .

It is a primary object of the present invention to provide an atomizer and a cartridge structure of such an atomizer, which can be applied to medical equipment to efficiently remove residues of liquid drugs through certain cartridge structures.

To achieve this object, the nebulizer comprises a cartridge structure and a spray device, the cartridge structure comprising a first cartridge receiving space and a second cartridge receiving space. The first cartridge receiving space includes one or more connection bottoms and a bottom connection position. The second cartridge receiving space includes one or more connecting sides and openings. The lower connection position of the first cartridge receiving space is connected to the second cartridge receiving space. In addition, the connecting bottom of the first cartridge receiving space is connected to the connecting side of the second cartridge receiving space to form an included angle, which is preferably a lead angle. The lead angle includes a chamfering angle and a fillet angle. The spray apparatus also includes a sprayer main body, a nozzle disk and a vibrating member. The sprayer main body has a control element, the nozzle disc is arranged in the opening of the second cartridge receiving space, and the vibrating member is coupled with the nozzle disc and electrically connected to the control element.

Therefore, the volume of the first cartridge accommodation space is larger than the volume of the second cartridge accommodation space. The spray device further utilizes a housing for covering the nozzle disk and the vibrating member. The structure formed by the connecting side of the second cartridge receiving space and the connecting bottom of the first cartridge receiving space may be a combination of geometric shapes. For example, the connecting bottom is inclined downward toward the connecting side to form inclination, and the connecting side is inclined downward toward the lower portion of the second cartridge receiving space to form a cambered surface. Alternatively, the bottom of the second cartridge receiving space slopes downward toward the opening.

The nebulizer and its cartridge structure disclosed by the present invention can effectively reduce the residue of liquid drug and prevent the generation of liquid drug waste.
