[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides Figure 1-5 The volume-controlled oral and nasal aerosol dispenser shown includes a storage tank 1. Both ends of the storage tank 1 are open structures and are respectively configured as a drug inlet end and a drug inhalation end. The drug inlet end of the storage tank 1 is provided with a cup ring 2, and a drug inlet port 201 is opened in the middle of the cup ring 2. The drug inlet port 201 is used for the entry of liquid medicine.

[0029] It should be noted that the cup ring 2 is made of silicone material, and the spray end of the sprayer can be inserted through the setting of the medicine inlet 201. After the spray end of the sprayer is inserted, after pressing the sprayer, the medicine liquid is sprayed into the storage tank 1 through the medicine inlet 201, and the atomized medicine liquid is in the storage tank 1 for the patient to inhale.

[0030] Also includes:

[0031] The inhalation mechanism is provided at the medicine inhalation end of the storage tank 1. The inhalation mechanism includes a barrier cover 3. A closed structure is provided between the barrier cover 3 and the inhalation end. An adjustment structure is provided between the barrier cover 3 and the tank body of the storage tank 1. The adjustment structure is used to adjust the size of the opening of the closed structure;

[0032] Specifically, the regulatory structure includes:

[0033] Support blocks 101, multiple support blocks 101 are arranged around the outer wall of the drug suction end of the storage tank 1;

[0034] Adjustment support grooves 303 , a plurality of adjustment support grooves 303 are circumferentially opened on the outer wall of the barrier cover 3 , and a plurality of support blocks 101 are respectively rotatably inserted and connected in the plurality of adjustment support grooves 303 .

[0035] It should be noted that the adjustment support groove 303 is composed of a vertical groove and multiple horizontal grooves that are opened through, and the multiple horizontal grooves are arranged at the vertical groove for support insertion. By inserting the support block 101 at different positions, the support block 101 cooperates with the adjustment support groove 303 to support the barrier cover 3 at different positions.

[0036] Specifically, the closed structure includes:

[0037] The closed baffle 6 is placed on the drug suction end of the storage tank 1;

[0038] The breathable cover 5 is sleeved on the inner wall of the barrier cover 3 , and the breathable cover 5 is arranged on a side of the closed baffle 6 away from the storage tank 1 .

[0039] It should be noted that the breathable cover 5 is used to allow air to flow freely during inhalation. Through such an arrangement, the medicine mist in the storage tank 1 can also be better ventilated and absorbed.

[0040] Furthermore, a ventilation hole is provided in the middle of the closed baffle 6 , and an elastic block 102 is provided at the drug suction end of the storage tank 1 , and the elastic block 102 is used to support the closed baffle 6 .

[0041] It should be noted that, by setting the elastic block 102, the closed baffle 6 is separated from the drug suction end of the storage tank 1, preventing the closed baffle 6 from completely fitting the drug suction end, and because the air vent and the hole of the drug suction end are staggered, such operation prevents the closed baffle 6 from completely blocking the drug suction end.

[0042] The mask mechanism is sleeved on one end of the inhalation mechanism away from the storage tank 1.

[0043] Specifically, an air suction nozzle 301 is provided at one end of the barrier cover 3 away from the storage tank 1 , and the air suction nozzle 301 is used to connect to the mask mechanism.

[0044] Furthermore, the mask mechanism includes a mask body 4 , a connecting sleeve 401 is provided in the middle of the mask body 4 , and the connecting sleeve 401 is sleeved on the outer wall of the suction nozzle 301 .

[0045] Furthermore, a plurality of docking strips 302 are provided around the outer wall of the suction nozzle 301 , and a plurality of docking slots 402 are provided around the inner wall of the connecting sleeve 401 . The plurality of docking strips 302 are respectively connected to the plurality of docking slots 402 in a sliding manner.

[0046] It should be noted that the sliding and interlacing between the docking strip 302 and the docking slot 402 makes the connection between the suction nozzle 301 and the connecting sleeve 401 smoother and more stable. At the same time, through such a structural coordination arrangement, the mask body 4 can be better connected to the barrier cover 3.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
