[0033] The fixing rope assembly 332 comprises a connecting rope 3321 and two rotating shafts for fixing the connecting rope 3321 on the mask 3. The two rotating shafts are symmetrically arranged at positions corresponding to the two protrusions 3331 on the two lateral sides of the mask 3, specifically, the rotating shafts are located on the sides of the corresponding protrusions 3331 away from the rubber ring 32. Each rotating shaft is L-shaped, that is, each rotating shaft comprises a first segment 3322 arranged in the width direction of the mask 3 and a second segment 3323 arranged in the direction perpendicular to the width direction. The first segment 3322 is rotationally connected with the mask 3, that is, the first segment 3322 can rotate around its own axis relative to the mask 3. The second segment 3323 is fixedly arranged at the end of the first segment 3322 away from the mask 3 and is perpendicular to the first segment 3322, and the second segment 3323 rotates with the rotation of the first segment 3322. The two ends of the connecting rope 3321 are fixedly connected with the ends of the two second segments 3323, specifically, the ends of the connecting rope 3321 are connected with the ends of the second segments 3323 away from the first segments 3322. It should be emphasized that the connecting rope 3321 is made of elastic material. The side of the sliding block 3332 facing the corresponding rotating shaft is provided with a clamping groove 3337, the clamping groove 3337 penetrates the sliding block 3332 upward, and the clamping groove 3337 penetrates the sliding block 3332 towards the rotating shaft. The width of the clamping groove 3337 matches the outer diameter of the second segment 3323.

[0034] The working mode of one of the embodiments of the oral-nasal spray drug delivery device is as follows: the spray is clamped in the clamping hole 41, the mask 3 is covered on the patient's face, and the mask 3 is further fixed by the fixing mechanism 33. The steps are as follows:

[0035] In the initial state, the second section 3323 is directed away from the protrusion 3331, so that the connecting rope 3321 is accommodated at a position away from the first end of the mask 3, and does not interfere with the action of covering the mask 3 on the patient's face. In the process of the mask 3 from contacting the patient's face to being tightly attached to the patient's face, the suction cup 331 gradually adheres to the patient's face, and the gas in the suction cup 331 enters the sliding groove 3334 through the air passage 3333 and pushes the sliding block 3332 to move out of the sliding groove 3334. When the sliding block 3332 moves to the outermost end of its stroke, the clamping groove 3337 is exposed outside the protrusion 3331, and at this time, rotating the rotating shaft makes its second section 3323 clamped into the clamping groove 3337. When the second section 3323 is clamped into the clamping groove 3337, the end of the second section 3323 points to the patient's face, and at this time, the connecting rope 3321 is sleeved on the back of the patient's head to play a role in fixing the mask 3. At the same time, the clamping of the second section 3323 into the clamping groove 3337 makes the sliding block 3332 unable to be retracted into the sliding groove 3334, and the suction cup 331 will not have the phenomenon of internal air leakage, and the adsorption is more firm. Because the suction cup 331 can deform with extrusion, and the rubber ring 32 can also deform with extrusion, when the suction cup 331 is adsorbed on the patient's face, the suction cup 331 is flattened due to extrusion and fills the corresponding recess 321, and the rubber ring 32 is tightly attached to the suction cup 331 due to extrusion, and there is no gap between the two and the patient's face, and the air tightness is good.

[0036] After use, reverse the above steps to restore the device to the initial state. When the device needs to be cleaned, the mask 3, the cover 2 and the end cap 4 can be removed from the tank 1 and cleaned separately, which is convenient and thorough.
