The filter holes are distributed in a circular array on the side wall of the counterweight ball, and a filter net is provided inside the filter holes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the anti-clogging asthma inhaler,

[0017] (1) The present invention can effectively solve the problem that the liquid medicine inside the existing asthma inhaler is easily stratified and precipitated due to long-term static standing, thereby causing the liquid medicine to block the device. When the asthma inhaler is used, the user is mostly in a state of discomfort, that is, an asthma attack, so it is easy to affect the user's normal treatment due to blockage, which poses a great safety hazard. When the device is not in use, it is hung on the user's backpack or clothing through a ring. At this time, under the action of gravity, the center of gravity of the shell and the medicine bottle is downward, and the ring is pulled upward by the rack under the tensile action of the hanging object. When the user holds the shell during an asthma attack, the above two groups disappear relative to each other. The force disappears, and at this time, the rack pushes the active toothed disc under the pull of the reset spring group to drive the medicine bottle to rotate, so that the stratified and precipitated medicine inside the medicine bottle diffuses outside under the action of centrifugal force to achieve mixing. At the same time, when the active toothed disc rotates, the medicine liquid on its inner wall will repeatedly collide with the counterweight ball to simulate stirring and mixing, thereby further preventing the stratification of the medicine liquid from causing blockage of the device. In addition, the filter net on the counterweight ball filters the medicine liquid entering the nozzle assembly to prevent it from clogging the nozzle assembly, thereby avoiding delays in the user's treatment due to blockage of the medicine liquid, and further avoiding the user's life being in danger due to untimely treatment. In addition, the entire anti-blocking operation does not require additional operations, that is, it is more convenient to use;

[0018] (2) The present invention can effectively solve the problem of insufficient centrifugal mixing by using a driven knocking assembly. When the active gear disc rotates, it pushes the driven gear disc to drive the driven rod to rotate together. When the driven rod rotates, it drives the fixed end of the cam to rotate. The fixed end of the cam drives the cam protrusion end to rotate through the telescopic spring group. When the cam protrusion end rotates and collides with the outer wall of the medicine bottle, the telescopic spring group is pressed under the driving force of the rotation and drives the cam protrusion end to move inward. When the outer wall of the medicine bottle is collided, the inner part diffuses outward under the action of centrifugal force, and the medicine attached to the outer wall is separated from the inner wall, thereby further improving the mixing effect of the medicine liquid and avoiding its blockage. The entire knocking operation does not require additional driving operation, thereby simplifying the operation process of the device.

[0019] (3) The present invention can effectively solve the problem that the length of most existing nozzles is not fixed and cannot be adjusted, thus failing to meet the usage requirements of different users through the coordinated use of the nozzle and the extension sleeve. When in use, the user can adjust the length of the nozzle extending into the mouth by sliding the extension sleeve on the nozzle, thereby facilitating the meeting of different usage requirements. At the same time, the staff can disassemble the inverted medicine bottle through the discharge port, and the disassembly process is relatively convenient. In addition, the inverted medicine bottle is convenient for ensuring the complete discharge of the internal medicine liquid, thereby improving the rationality of the device structure.

[0031] In a further embodiment, the top of the medicine bottle 201 is threadedly connected to the spray head assembly 6 , and the spray head assembly 6 is rotatably connected to the housing 1 .

[0032] In a further embodiment, the active gear disc 203 is arranged inside the discharge port 4, and the discharge port 4 is opened at the bottom of the shell 1, and grooves 3 are opened on the inner wall of the shell 1 at equal intervals.

[0033] In a further embodiment, the rack 204 is slidably connected inside the slide slot 5 , and the slide slot 5 is opened on the side wall of the housing 1 .

[0034] In a further embodiment, the driven striking assembly 209 includes a driven rod 2091, a driven gear plate 2092, a cam fixed end 2093, a telescopic spring group 2094 and a cam protrusion end 2095, and the driven rod 2091 is connected with the driven gear plate 2092 and the cam fixed end 2093, the driven gear plate 2092 is arranged below the cam fixed end 2093, and the driven gear plate 2092 is connected to the cam protrusion end 2095 through the telescopic spring group 2094, and the telescopic spring group 2094 is evenly distributed between the cam fixed end 2093 and the cam protrusion end 2095.

[0035] In a further embodiment, the driven gear disc 2092 is meshingly connected with the driving gear disc 203 , and the driven gear disc 2092 is disposed on one side of the driving gear disc 203 .

[0036] In a further embodiment, three groups of cam fixed ends 2093, telescopic spring groups 2094 and cam protrusion ends 2095 are provided, and the cam fixed ends 2093, telescopic spring groups 2094 and cam protrusion ends 2095 are provided corresponding to the groove 3, the cam fixed ends 2093, telescopic spring groups 2094 and cam protrusion ends 2095 are provided on one side of the medicine bottle 201, and a counterweight ball 10 is provided inside the medicine bottle 201, and the diameter of the counterweight ball 10 is smaller than the inner wall diameter of the medicine bottle 201.

[0037] In a further embodiment, the rotating mechanism 2 further includes a support plate 2010 , and the support plate 2010 is rotatably connected to the driven rod 2091 , and the support plate 2010 is fixedly connected to the inside of the discharge port 4 .

[0038] In a further embodiment, the counterweight ball 10 is connected to the nozzle assembly 6 through the extraction pipe 9, and a filter hole 11 is opened on the counterweight ball 10. The filter holes 11 are distributed in a circular array on the side wall of the counterweight ball 10, and a filter net 12 is arranged inside the filter hole 11.

[0039] Specifically, in the actual working process, the medicine bottle 201 storing the medicine liquid is firstly threadedly connected to the spray head assembly 6. After the connection is completed, the counterweight ball 10 is located inside the medicine bottle 201, and the active gear plate 203 is meshed with the driven gear plate 2092 and the rack 204. Then, it is hung on the user's backpack or clothes through the ring 206. At this time, under the action of gravity, the center of gravity of the shell 1 and the medicine bottle 201 is downward, and the ring 206 is stretched by the rack 204 sliding in the slide groove 5 to pull the reset spring group 208 to extend. When an asthma attack occurs, the user holds the housing 1 and inserts the nozzle 7 into the mouth, and then presses the nozzle assembly 6 so that the liquid in the medicine bottle 201 is filtered by the filter screen 12 on the counterweight ball 10 and then sprayed out through the nozzle 7. When the user holds the housing 1, the above two groups of relative forces, namely gravity and tensile force, disappear. At this time, the rack 204 pushes the active gear disc 203 under the pull of the return spring group 208 to drive the medicine bottle 201 to rotate, so that the stratified precipitated drugs inside the medicine bottle 201 are diffused to the outside under the action of centrifugal force to achieve mixing.

[0040] On the other hand, when the active gear disc 203 rotates, it pushes the driven gear disc 2092 to drive the driven rod 2091 to rotate together. When the driven rod 2091 rotates, it drives the cam fixed end 2093 to rotate. The cam fixed end 2093 drives the cam protrusion end 2095 to rotate through the telescopic spring group 2094. When the cam protrusion end 2095 rotates and collides with the outer wall of the medicine bottle 201, the telescopic spring group 2094 is pressed under the driving force of the rotation and drives the cam protrusion end 2095 to move inward. When the outer wall of the medicine bottle 201 is collided, the medicine attached to the outer wall and the inner wall are diffused outward under the action of centrifugal force. The wall is separated. At the same time, since the contact time between the three groups of cam protrusion ends 2095 and the outer wall of the medicine bottle 201 is different, that is, the medicine bottle 201 and the driven rod 2091 rotate one circle in the same time, the three groups of cam protrusion ends 2095 continuously attack and hit the medicine bottle 201 three times, thereby further improving the mixing effect of the medicine liquid and avoiding blockage. When the active toothed disc 203 rotates, the medicine liquid on its inner wall will repeatedly collide with the counterweight ball 10 to simulate stirring and mixing. At the same time, the user can manually press the pressure plate 205 to prompt the active toothed disc 203 to drive the medicine bottle 201 and the driven knocking component 209 to rotate to mix the medicine.

[0044] Specifically, during use, the user can adjust the length of the extension sleeve 8 extending into the mouth by sliding the position of the extension sleeve 8 on the nozzle 7, thereby facilitating meeting different usage requirements.
