[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides an aerosol drug delivery device, such as Figure 1-Figure 5 As shown, it includes a tank body 1, a bellows 2 is provided in the middle of the tank body 1, which is convenient for expansion and contraction, so as to realize the volume adjustment of the tank body 1, an end cover 3 is installed at one end of the tank body 1, and an air outlet 4 is installed at the other end of the tank body 1 for discharging aerosol, a one-way ventilation component 5 is installed inside the air outlet 4 for one-way flow of gas, a sealing cover 6 is installed outside the air outlet of the air outlet 4 for sealing the air outlet 4, and telescopic locking components 7 are installed on the outer walls of both sides of the tank body 1, the bellows 2 can be telescopically adjusted in length, and is locked and fixed by the telescopic locking component 7, which is convenient for locking and fixing the bellows 2 after adjusting the length.

[0024] In this embodiment, a pull rope 61 is connected to the outer side of the sealing cover 6 , and one end of the pull rope 61 away from the sealing cover 6 is connected to the outer wall of the air outlet end 4 , so as to facilitate the installation and fixation of the sealing cover 6 .

[0025] Specifically, the one-way ventilation assembly 5 includes a ventilation pipe 55, and two one-way flaps 51 are symmetrically arranged inside the ventilation pipe 55. One end of each one-way flap 51 is hingedly connected to the inner wall of the ventilation pipe 55 through a hinge 52, and a spring 53 is installed between the other end of each one-way flap 51 and the inner wall of the ventilation pipe 55. The other ends of the two one-way flaps 51 are brought together by the elastic force of the spring 53, so as to facilitate the compression and sealing between the other ends of the two one-way flaps 51.

[0026] Furthermore, a sealing pad 56 is installed at one end of each one-way flap 51 hinged on the inner wall of the vent pipe 55, and a sealing strip 54 is installed between the side surfaces of the ends of the two one-way flaps 51 that are close together. The sealing strip 54 is used to ensure the sealing of the ends of the two one-way flaps 51 that are close together.

[0027] Furthermore, the telescopic locking assembly 7 includes a sleeve 71, and a movable rod 72 is inserted into one end of the sleeve 71. The movable rod 72 is locked on the sleeve 71 by a locking bolt 73. The end of the movable rod 72 located outside the sleeve 71 is fixedly connected to the outer wall of one end of the tank body 1, and the other end of the sleeve 71 is connected to the outer wall of the air outlet end 4. The length of the bellows 2 is adjusted by the telescopic movement of the movable rod 72, and then the length of the bellows 2 is fixed by tightening the locking bolt 73.

[0028] Furthermore, the end of the tank body 1 away from the gas outlet 4 has an opening and is equipped with an end cap 3. The middle of the end cap 3 is provided with an air inlet 32. The inner wall of the air inlet 32 ​​is provided with a sealing ring 33 to facilitate the connection of the sprayer. When the device is not in use, a sealing plug 321 is installed at the air inlet 32 ​​to block the air inlet 32, thereby ensuring the sealing of the inside of the tank body 1 and preventing contamination.

[0029] Furthermore, a threaded ring 31 is installed on one side of the end cover 3 close to the tank body 1 , and the threaded ring 31 is threadedly connected to an opening at one end of the tank body 1 , so as to facilitate the installation and fixation of the end cover 3 .

[0030] Furthermore, the outer wall of the one-way flap 51 is provided with an inclined surface to facilitate the flow of the aerosol and enable the drug to flow to the air outlet 4 .

[0031] When the aerosol drug delivery device of the utility model is used, firstly, before use, the user can adjust the length of the bellows 2 as needed, thereby changing the total volume of the tank body 1. The bellows 2 is extended and retracted by the telescopic locking components 7 installed on both sides. Specifically, the user can pull or push the movable rod 72 to make it telescopically move in the sleeve 71, and then fix the movable rod 72 at a desired position by the locking bolt 73, thereby achieving the adjustment and locking of the length of the bellows 2.

[0032] When medication is required, the sealing plug 321 is removed from the air inlet 32, and then the spray port of the sprayer is inserted into the air inlet 32, so that the sprayer fills an appropriate amount of aerosol medicine into the tank body 1 through the air inlet 32, and when the user inhales the medicine, the sprayer is inserted on the air inlet 32 ​​to ensure the sealing of the inside of the tank body 1.

[0033] Then, the user can open the sealing cover 6 and prepare to inhale the medicine. In this process, the one-way ventilation component 5 plays a key role. When the user inhales, the external air pressure decreases, and the aerosol medicine inside the tank body 1 flows to the air outlet 4 under the action of the pressure difference. At this time, the one-way flap 51 is squeezed by the medicine airflow and opens, allowing the medicine to flow out to the air outlet 4 through the ventilation tube 55 for the user to inhale.

[0034] Since the outer wall of the one-way flap 51 is provided with an inclined surface, when the drug airflow flows through, the guiding effect of the inclined surface helps the smooth flow of the aerosol and reduces the resistance. At the same time, the elastic force of the spring 53 ensures that the one-way flap 51 can be quickly closed after the drug flows out, preventing external air and impurities from entering the tank body 1 to contaminate the drug.

[0035] When the user stops inhaling, the ends of the two one-way flaps 51 are tightly closed under the elastic force of the spring 53 to prevent drug leakage.

[0036] After use, the user can use the pull rope 61 to tightly cover the sealing cover 6 on the air outlet 4, then pull out the sprayer and insert the sealing plug 321 into the air inlet 32. At the same time, the design of the pull rope 61 also makes it convenient for the user to carry and use the device at any time.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
