[0046] Further, the suction nozzle 2 and the suction nozzle cap 50 are clamped, and the top and bottom inner walls of the suction nozzle cap 50 are provided with clamping parts, and the top and bottom side walls of the suction nozzle 2 are correspondingly provided with clamping parts, so that the suction nozzle 2 and the suction nozzle cap 50 are clamped;

[0047] Further, in order to prevent the suction nozzle 2 and the suction nozzle cap 50 from being too tightly clamped to be inconvenient to separate, the suction nozzle cap 50 extends to both sides of the suction nozzle cap 50 at both ends of the second direction, so that the suction nozzle cap 50 has a gap between both ends of the second direction of the suction nozzle cap 50 and the side walls of the second direction of the suction nozzle 2. Thus, when in use, the suction nozzle cap 50 is deformed by pinching both sides of the suction nozzle cap 50, so that the clamping part of the suction nozzle 2 and the suction nozzle cap 50 is separated, and then the suction nozzle 2 and the suction nozzle cap 50 are separated, which is convenient for use.

[0048] The medicine bottle 3 comprises a bottle body, a telescopic rod arranged at the bottom of the bottle body, and a nozzle 4 connected to the bottom of the telescopic rod. By pressing the nozzle 4, the telescopic rod is retracted into the bottle body, so that the medicine can be sprayed from the nozzle 4. The medicine bottle 3 is movably arranged in the shell 1, and the nozzle 4 is aligned with the suction nozzle 2.

[0049] Further, after the medicine bottle 3 is pressed, the medicine is diffused and sprayed from the nozzle 4. In order to avoid waste of the medicine, the nozzle 4 extends towards the suction nozzle 2, shortens the distance between the nozzle 4 and the patient's mouth, and avoids waste caused by premature diffusion of the medicine.

After the compression of the spring 16 is released, the spring force of the spring 16 can push the spring seat push sleeve 13 to move in the first direction, thereby pushing the bottle body to move in the first direction, and further pressing the telescopic rod and the nozzle 4 to make the telescopic rod retract, so that the nozzle 4 can spray the medicine.

[0054] It should be noted that the containing groove can limit the spring 16. During the contraction and release of the spring 16, the spring 16 is prevented from deviating, and the direction of the spring force of the spring 16 is always in the first direction, so that the spring seat push sleeve 13 can be stably pushed.

[0102] In this process, the elastic force of the first torsion spring 34 is also released, because the spring seat push sleeve 13 moves downward along the first direction, and the clip seat 27 is located in the upper cover 7, so that the second rotating part 37, the second rotating shaft 38 and the clip 35 all rotate around the first rotating shaft 29, so that the poking finger 36 is disengaged from the first tooth groove, and under the action of the second torsion spring 39, it rotates around the second rotating shaft 38 and always abuts against the poking turntable 25 and moves along the circumference of the poking turntable 25, and finally is located outside the second tooth groove adjacent to the first tooth groove;

[0103] After the patient uses it, by pressing the button 48, the button 48 moves upward along the first direction, pushing the reset push block 44 to move upward, so that the reset push block 44 pushes the bottle body to move upward, the bottle body pushes the spring seat push sleeve 13 upward, so as to compress the spring 16, and the elastic assembly is switched from the natural state to the compressed state, at the same time, the connecting rod assembly is changed from the second state to the first state, the magnet 5 and the magnetic attraction piece 6 are attracted to each other, ensuring the dead center balance of the first connecting rod 20 and the second connecting rod 21, at this time, the first identification part 41 corresponds to the second window 43, indicating that the device can be used;

[0104] In this process, the spring seat push sleeve 13 moves upward along the first direction, the abutting block 33 pushes the second connecting block 32, so that the second connecting block 32 rotates around the first rotating shaft 29, so that the second rotating part 37, the second rotating shaft 38 and the clip 35 all rotate around the first rotating shaft 29, and under the action of the second torsion spring 39, the poking finger 36 extends into the second tooth groove and abuts against the second tooth groove, so as to push the poking turntable 25 to rotate, drive the digital disc 24 to rotate, so that the number displayed by the first window 12 is switched once;

[0105] It should be noted that the device is used once, the number displayed by the first window 12 is switched once, because the depth of the tooth groove corresponding to the number 9 is deeper than other tooth grooves, and the length of the three poking fingers 36 decreases in the direction from the unit place to the hundred place, therefore, the poking finger 36 corresponding to the number plate 24 of the unit place is first pushed to rotate the number plate 24 of the unit place, when the number 9 on the number plate corresponds to the first window 12, after the next use of the device, the poking finger 36 extends into the tooth groove corresponding to the number 9, so that the poking finger 36 corresponding to the number plate 24 of the ten place extends into the tooth groove of the poking dial 25 on the number plate 24 of the ten place, and then pushes the number plate 24 of the ten place and the number plate 24 of the unit place to rotate at the same time, such as the number switching from 009 to 010, similarly, in the process of the number switching from 099 to 100, the poking finger 36 corresponding to the number plate 24 of the unit place and the poking finger 36 corresponding to the number plate 24 of the ten place respectively extend into the tooth groove corresponding to the number 9 on the poking dial 25, so that the poking finger 36 corresponding to the number plate 24 of the hundred place pushes the poking dial 25 of the hundred place to rotate, thereby the device is used once to realize once counting, indicating the number of times the device has been used, facilitating timely replacement after the medicine in the medicine bottle is used up, avoiding the patient not knowing whether the medicine is used up, thereby avoiding the emergence of unexpected situations.

[0106] If the device is not restored after use, the second window 43 displays the second identification part 42, the patient can check the condition of the second window 43 before use, avoiding the failure to inhale the medicine; meanwhile, the text mark of "reset after use" is made on the side wall of the lower shell 9, avoiding the patient forgetting to reset after use, and avoiding the emergence of unexpected situations in the next use.
