[0020] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0021] Unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] As shown in the figure, a one-way filling respiratory drug delivery device is applied to a mask body 1. The mask body 1 is an integrated symmetrical structure. Both sides of the mask body 1 are provided with runway-shaped fixing holes 14 for fixing. The fixing holes 14 realize the fixation of the mask body 1, which is convenient for people to wear.

[0023] A breathing valve body 2 is provided on one side above the mask body 1, and medication is administered by breathing through the breathing valve body 2. The breathing valve body 2 includes a base 3 and an upper cover 4, one end of the upper cover 4 is connected to one side of the base 3 to prevent the upper cover 4 from being lost. A connecting pad 15 connected to the mask body 1 is provided on the outer edge of the base 3 to facilitate the fixing of the breathing valve body 2.

[0024] A protruding boss 6 is provided at the center of the groove of the limiting ring 5 inside the base 3, and the limiting ring 5 prevents the added liquid from flowing out and improves the stability of the connection between the upper cover 4 and the base 3. A one-way liquid adding hole 7 is provided at the center of the groove of the inverted cone structure on the boss 6, and liquid is added through the one-way liquid adding hole 7, and its inverted cone groove structure prevents liquid from overflowing.

[0025] The center of the upper cover 4 is provided with a sealing ring 8 corresponding to the top of the protrusion 6, and the sealing ring 8 ensures the sealing of the protrusion 6 to prevent liquid from overflowing. The outer side of the sealing ring 8 is provided with a fixing ring 9 corresponding to the outer side of the protrusion 6, and the fixing ring 9 further improves the sealing effect of the protrusion 6.

[0026] A water-absorbing breathing sheet 10 is provided in the cavity on the inner side of the base 3, and the liquid medicine on the water-absorbing breathing sheet 10 can enter the body through breathing and be slowly released to the human body. A chuck 11 connected to the inner side of the base 3 is provided on the outer side of the breathing sheet 10, and the chuck 11 fixes the water-absorbing breathing sheet 10. An air hole 12 is provided on the chuck 11, and the liquid medicine on the water-absorbing breathing sheet 10 can be prevented from leaking out through the air hole 12. A clamping protrusion 13 connected to the base 3 is provided on the outer edge above the chuck 11, and the position of the chuck 11 is fixed by the clamping protrusion 13. An air hole 12 is also provided on the support plate below the protrusion 6, and the support plate can fix the water-absorbing breathing sheet 10, and the air hole 12 facilitates the addition of liquid medicine.

[0027] When in use, by opening the upper cover 4, the liquid medicine is added to the water-absorbing breathing sheet 10 from the one-way liquid adding hole 7, so that the one-way addition of the liquid medicine on the breathing sheet 10 and the internal volatilization and slow release are realized.

[0028] Therefore, the present invention adopts the above-mentioned one-way filling breathing drug delivery device, which has a simple structure, good protection effect and low production cost.
