Description

Technical Field

[0001] The present invention relates to the technical field of soft mist inhalation devices, and particularly to a medicine bottle for a soft mist inhaler and a soft mist inhalation device. Background Art

[0002] A soft mist inhaler is a new type of inhalation preparation. On the one hand, it uses the mechanical energy generated by compressing a spring as the power to provide energy for the drug to release aerosol. On the other hand, through capillary precise quantification and the principle of the collision of two unique liquid medicine jets, it forms a unique "soft mist" by hitting at a specific angle. After the human body inhales the atomized drug, it achieves the therapeutic effect. Compared with oral and intravenous drug administration, it can make the drug act directly on the respiratory mucosa and alveoli, having the advantages of rapid onset, good curative effect, small drug dosage, good safety, and convenient use.

[0003] In a soft mist inhaler, a mechanical driving device is usually required to quickly compress the liquid medicine and send the liquid medicine out of the atomization chip at a high speed, so as to achieve the purpose of shearing to form droplets. Specifically, most often, the mechanical energy is stored by a compression spring in the mechanical driving device, and then the compression spring is released when needed to push the piston in the medicine cartridge to squeeze the liquid medicine, so that the liquid medicine is quickly sheared and ejected from the atomization chip opening to form atomized droplets, and the compression spring is reset after use. The structures of conventional mechanical driving devices are of two types: rotary type and direct push type. Each of these two structures has its own advantages and disadvantages, among which: The rotary driving structure has high operation stability, low risk of accidental touch, and strong durability. However, its structure is complex, the production and manufacturing cost is high, and the operation complexity during resetting and tightening is relatively high, requiring high flexibility of the hand, which may not be suitable for children, the elderly, or patients with limited hand mobility; The direct push driving structure has simple and intuitive operation. In the scenario of first aid or rapid drug administration, the direct push design can reduce the operation steps and improve the use efficiency, and the structure is simple and easy to manufacture. However, the linear compression spring in the direct push driving structure requires a large thrust during the reset operation, which may not be user-friendly to children, the elderly, or patients with weak hand strength. In addition, the difference in the user's thrust may cause inconsistent compression of the spring, affecting the atomization effect and resulting in relatively poor atomization consistency. In addition, due to the structural limitation of the direct push driving structure, its stability is weak when pushing to form droplets, and the push rod is prone to deviate from the axis, affecting the atomization effect and reducing the service life accordingly.

[0004] In view of this, a new type of direct push soft mist generation driving device has been developed. During this process, it has also been found that the disassembly and assembly of the existing medicine bottle for a soft mist inhaler are relatively complex, which is not conducive to user use. In addition, most of the existing medicine bottles achieve the purpose of replacing the liquid medicine by replacing the bottle body, and the atomization chip is reused, which may lead to the possibility of cross-contamination and cannot meet the atomization particle requirements of different liquid medicines.

[0005] Therefore, how to improve the structure of the medicine bottle and the generating driving device of the soft mist inhaler to at least overcome one of the above-mentioned defects is the technical problem to be solved by this application. Summary of the Invention

Detailed Embodiment

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1: This example describes a medicine bottle 2 for a soft mist inhaler, as Figure 1 and Figure 2 shown, which includes: A bottle body 29, inside which a plunger 22 made of rubber is provided. The plunger 22 divides the inner cavity of the bottle body 29 into a sealed space for storing the liquid medicine. The distal end of the bottle body 29 has a thread or a buckle (in this example, an internal thread 28 is adopted, and the internal thread 28 is adapted to the connecting part 111 of the bottle body 29 of the soft mist generating driving device); An atomization module is sequentially arranged at the outlet end of the bottle body 29. The atomization module includes a filter element 23 and an atomization chip 21. The filter element 23 is located between the sealed space and the atomization chip 21. The atomization chip 21 is fixedly assembled at the outlet position of the bottle body 29. The atomization chip 21 is a piezoelectric microporous atomization chip 21 or an ultrasonic atomization chip 21, and its spray hole diameter is 1 - 10 μm; An elastic member 24 is arranged outside the atomization chip 21, and a support member 25 is arranged outside the elastic member 24. The support member 25 is fixedly connected to the outlet end of the bottle body 29; When an external force is applied to push the plunger 22, the liquid medicine enters the atomization chip 21 through the filter element 23 and is atomized by the atomization chip 21 to form mist droplets and spray out.

[0028] For the medicine bottle 2 of the soft mist inhaler in this example, a standardized interface (such as a card slot, a thread or an interference fit) is adopted with an external force application mechanism to realize the quick disassembly and assembly of the medicine bottle 2 and the soft mist generating driving device. Users can replace the independent medicine bottle 2 pre-filled with the liquid medicine according to different treatment requirements (such as the type of liquid medicine, dosage difference), avoiding cross-contamination and reducing the use cost at the same time.

[0029] In one embodiment, the elastic member 24 is a silicone ring or a spring, and its inner diameter is adapted to the outer peripheral dimension of the atomization chip 21 to provide a radial pre-tightening force. The support member 25 is a ring structure made of metal or plastic, and its inner wall is provided with a card slot or a thread, and is in interference fit or screwed and fixed with the outlet end of the bottle body 29.

[0030] The combined design of the elastic member 24 and the support member 25 is adopted to fix the atomization chip 21 through the radial pre-tightening force, buffer the impact of the liquid medicine pressure fluctuation on the atomization chip 21, and prevent uneven atomization or chip damage caused by sudden pressure change.

[0031] In one embodiment, the pore size of the filter element 23 is 0.1 to 10 micrometers, which is used to filter particulate impurities in the liquid medicine. The microporous filtration of the filter element 23 can intercept large particulate impurities in the liquid medicine, avoid clogging of the spray holes of the atomization chip 21, and extend the service life of the chip.

[0032] In addition, a buffer cavity 26 is formed between the filter element 23 and the atomization chip 21, and the volume of the buffer cavity 26 is 0.1 to 1 mL. The buffer cavity 26 further adjusts the flow rate of the liquid medicine to ensure the pressure stability during the atomization process.

[0033] In order to further improve the bonding stability of the components at the outlet end, a cap 27 is provided at the outlet end of the bottle body 29. The cap 27 covers the support member 25 and is threadedly fastened to the bottle body 29, and is used to assist in closing the filter element 23, the atomization chip 21 and the support member 25 at the outlet end of the bottle body 29.

[0034] In addition, a groove or protrusion (in this embodiment, a groove form is adopted) is provided at the distal end of the plunger 22 as a clamping portion 221, which is used for fitting connection with the push rod 3 of an external force application mechanism.

[0035] In order to prevent the interior of the medicine bottle 2 and the bottle mouth from being contaminated, a bottle cap is usually provided at the bottle mouth. In order to be able to see the internal medicine dosage, a window is provided on the bottle body of the medicine bottle 2, and even scale marks are added to the window. However, this is a conventional design and will not be elaborated here. It should be understood that all of them should be within the scope of protection of this application.

[0036] Designing the connection between the medicine bottle 2 and the soft mist generation driving device in the soft mist inhalation device as a detachable connection can bring the following effects: 1. Improve the convenience of use Flexible replacement of medicines: Users can quickly replace different medicines (such as different dosages or formulations) without replacing the entire device, which is especially suitable for patients who need to frequently switch medicines (such as alternating treatment of asthma and chronic obstructive pulmonary disease).

[0037] Simplify the operation process: The detachable design facilitates the installation and removal of the medicine bottle, reduces the operation complexity, and is especially more user-friendly for the elderly or users with limited mobility.

[0038] 2. Reduce costs and environmental friendliness Reuse the driving device: Only replace the medicine bottle instead of the whole set of equipment, reduce material waste, and lower the long-term use cost (such as purchasing replacement cartridges after the medicine is used up).

[0039] 3. Enhance maintenance and cleaning Possibility of deep cleaning: The separable design facilitates the separate cleaning of the medicine bottle and the driving device, avoids the pollution or blockage of the atomization components caused by the residual medicine, and extends the service life of the equipment.

[0040] Targeted maintenance: If the medicine bottle or the drive part is damaged, it can be replaced or repaired separately, reducing maintenance costs.

[0041] 4. Compatibility and personalized medicine Compatible with multiple types of medicines: Adapt to medicine bottles from different manufacturers (such as pre-filled or self-filling types) through a standardized interface, improving the versatility of the device.

[0042] Customized treatment: Patients can choose different drug combinations according to their needs and flexibly adjust the treatment plan.

[0043] 5. Safety and hygiene optimization Avoid cross-contamination: Discard the medicine bottle after single use, and the contact part of the drive device can be disinfected, reducing the risk of infection.

[0044] Sealing guarantee: The detachable connection can be designed as a snap or threaded structure to ensure no leakage during atomization and maintain the accuracy of the drug dose.

[0045] Therefore, the soft mist inhaler with a detachable connection component can significantly improve the user experience, economy, and environmental friendliness through modular design. It can not only be applicable to home medical care, facilitating patients to replace the medicine bottle at home and reducing the need for professional maintenance, but also be adapted to the clinic, enabling rapid switching of test drugs, improving efficiency while reducing costs. This is an important trend in the humanization and intelligentization of medical devices.

[0046] Example 2: This example describes a soft mist inhaler, as Figure 3 and Figure 8 shown. It includes a soft mist generation drive device and a medicine bottle for a soft mist inhaler as described in Example 1. The distal tail of the bottle body of the medicine bottle for a soft mist inhaler is connected in butt joint with the bottle body connection part of the soft mist generation drive device through a thread or a snap. The soft mist generation drive device, as an external force application mechanism, has a push rod that can apply an external force. The push rod is connected to the plunger and is used to push the plunger along the axis direction of the bottle body.

[0047] The medicine bottle for a soft mist inhaler of the present application combined with the soft mist generation drive device forms a soft mist inhaler, which is simple to operate, has low usage requirements, and can meet the needs of different people. Moreover, the soft mist generation drive device of the present application forms a cylinder through inner and outer sleeves during operation, which can not only improve the stability during drive propulsion but also achieve the rapid reset of the push rod on this basis.

[0048] Example 3: This example describes a soft mist inhaler, as Figures 3 to 7 shown. It includes a soft mist generation drive device and a medicine bottle for a soft mist inhaler as described in Example 1.

[0049] Specifically, the soft mist generating driving device comprises a cylinder 1, a spring 4, a push rod 3 and a spring 4; The cylinder 1 is columnar, the spring 4 and the push rod 3 are both arranged in the cylinder 1, and the spring 4 is used to drive the push rod 3 to translate along the radial direction of the inner sleeve 12; The push rod 3 passes through one end of the cylinder 1, and a bottle body connecting portion 111 is provided at one end of the cylinder 1, and the bottle body connecting portion 111 is a threaded connecting portion or a bayonet connecting portion; A locking device 5 that can be triggered and released is disposed between the cylinder 1 and the push rod 3 , and a trigger mechanism 51 of the locking device 5 is disposed on the surface of the cylinder 1 .

[0050] When in use, the medicine bottle 2 can be connected to the barrel 1 through the bottle body connecting part 111, and the end of the push rod 3 passing through the barrel 1 contacts the plunger 22 of the medicine bottle 2. At this time, the spring 4 is in a compressed state; after the trigger mechanism 51 is activated, the locking device 5 is internally disengaged and switches from a locked state to a free state. The spring 4 quickly changes from a compressed state to a free state. The spring 4 pushes the push rod 3, and the end of the push rod 3 passing through the barrel 1 pushes the plunger 22 in the barrel 1. The plunger 22 then pushes the medicine in the medicine bottle 2 to the outlet, and the atomizer chip 21 arranged at the outlet of the medicine bottle 2 further atomizes and sends the medicine out.

[0051] In an optimized implementation, the cylinder body 1 is designed as an inner and outer sleeve structure, that is, it can generally include an inner sleeve 12 and an outer sleeve 11, the inner sleeve 12 is arranged in the outer sleeve 11 and slidably cooperates with the outer sleeve 11, and the inner sleeve 12 is fixedly connected to the push rod 3.

[0052] The inner sleeve 12 is sleeved inside the outer sleeve 11, and there is a clearance fit between the inner sleeve 12 and the outer sleeve 11, so that the inner sleeve 12 can move freely in the outer sleeve 11. In addition, a guide or limiting structure can be provided between the outer sleeve 11 and the inner sleeve 12, for example, a stepped guide structure is adopted, a flange guide rail 122 is provided on the outer wall of the inner sleeve 12, and a guide groove 113 is correspondingly provided on the outer sleeve 11, and the flange guide rail 122 is clamped in the guide groove 113, and the guide groove 113 is preferably provided along the axial direction of the cylinder body 1, so that the inner sleeve 12 can move stably in the outer sleeve 11. It is worth noting that if the guide groove 113 is provided in the form of a through groove, and the flange guide rail 122 is provided in a shape protruding from the outer wall of the outer sleeve 11, then the flange guide rail 122 can also be used as a setting for compressing and resetting the inner sleeve 12.

[0053] Specifically, in one embodiment, the outer sleeve 11 is a cylindrical tube. The outer sleeve 11 has opposite first and second ends, and both the first end and the second end are closed. A through hole is provided in the first end, and the first end of the push rod 3 passes through the through hole. For ease of description, the end of the cylinder 1 that is docked with the medicine bottle 2 is defined as the first end, that is to say, the end of the cylinder 1 provided with the bottle body connection portion 111 is the first end, and the other end of the cylinder 1 away from the bottle body connection portion 111 is defined as the second end. Correspondingly, the end through which the push rod 3 passes through the through hole is the first end of the push rod 3, and the other end away from it is the second end of the push rod 3. The spring 4 is arranged between the second end of the push rod 3 and the second end of the outer sleeve 11.

[0054] By closing both ends of the hollow outer sleeve 11 to form a cavity structure, the inner sleeve 12, the push rod 3, the spring 4, etc. are all arranged in this relatively closed cavity. After being enclosed in the cavity, each component is not easily damaged, and the limiting effect from above and below can initially limit the working stroke of the push rod 3, improving the reliability and consistency of its pushing action.

[0055] In addition, a through hole through which the push rod 3 can pass is provided in the closed first end, and the diameter of this through hole is slightly larger than the diameter of the push rod 3. When the push rod 3 is moving, the through hole can play a role in limiting the push rod 3, preventing it from deviating or deviating too much in the axial direction. Such a design can prevent the push rod 3 from shaking, ensure stable force application when pushing the plunger 22 of the medicine bottle 2, not only ensure consistent thrust and stable atomization effect, but also avoid the reduction of the service life of the device caused by the shaking of the push rod 3.

[0056] In this embodiment, the locking device 5 can be used to hold the push rod 3 in the compressed state of the spring 4, so that the push rod 3 can be in a stable state and can be quickly released after being triggered. Through the structural design of the locking device 5, the limiting of the compressed position of the spring 4 can be realized, the consistent reset setting of the driving force can be realized, and the control of the atomization consistency can be realized.

[0057] In one embodiment, the locking device 5 includes a trigger mechanism 51, a locking tongue 52 and a locking buckle 53. The trigger mechanism 51 is arranged on the outer sleeve 11, one of the locking tongue 52 and the locking buckle 53 is connected to the trigger mechanism 51, and the other is arranged on the inner sleeve 12. The trigger mechanism 51 is used to control the release of the fixation between the locking tongue 52 and the locking buckle 53.

[0058] It can be understood that one of the locking tongue 52 and the locking buckle 53 is provided at the outer sleeve 11, and the other is provided at the inner sleeve 12. The clamping and locking between the locking tongue 52 and the locking buckle 53 can complete the relative fixation between the outer sleeve 11 and the inner sleeve 12. The locking buckle 53 is usually designed as a groove or a hole for accommodating the locking tongue 52 to achieve locking. When the locking device 5 is in the locked state, the locking tongue 52 protrudes and is embedded in the locking buckle 53. In order to enable the locking tongue 52 to maintain a certain elastic vitality, elastic components such as a spring 4 and a damping member can be used to keep the locking tongue 52 in the locking buckle 53, which can also enable the locking tongue 52 to return to its place during reset. The triggering mechanism 51 preferably uses a button trigger. When the button is pressed, through mechanical linkage, such as a lever or a connecting rod, the locking tongue 52 can be pulled back or pushed out, so that the locking tongue 52 disengages from the locking buckle 53, allowing the inner sleeve 12 to separate from the outer sleeve 11, that is, switching the inner and outer sleeves 11 to the unlocked state. The spring 4 at the second end of the push rod 3 starts to stretch from the compressed state, pushing the push rod 3, and then pushing the plunger 22 in the medicine bottle 2, forming a mist spray.

[0059] In this embodiment, the locking tongue 52 on the inner sleeve 12 is made of an elastic material with certain damping characteristics. By pressing the locking tongue 52 downward through the triggering mechanism 51 (button type), the locking tongue 52 is separated from the locking buckle 53. After the locking tongue 52 and the locking buckle 53 are disengaged, the inner sleeve 12 and the push rod 3 can be released. The spring 4 pushes the push rod 3, and finally the plunger 22 in the medicine bottle 2 is pushed towards the bottle mouth to form a mist of the liquid medicine. When resetting, pulling back the locking tongue 52 can drive the inner sleeve 12 to move towards the second end of the outer sleeve 11, and the push rod 3 compresses the spring 4 to return to the compressed state. After the locking tongue 52 is re-engaged with the locking buckle 53, the locking device 5 resumes locking, and the driving and resetting of the soft mist generating driving device can be completed.

[0060] In an embodiment, a through groove 112 is axially formed on the outer sleeve 11, and a positioning protrusion 121 is provided on the inner sleeve 12. The positioning protrusion 121 is clamped in the through groove 112. This design can achieve the restoration of locking after the locking device 5 is released and unlocked. It can be known that when the locking is released, the spring 4 stretches until the inner sleeve 12 or the push rod 3 reaches the limit position, or the spring 4 basically returns to the free state, and the inner and outer sleeves 11 will maintain a relatively stable state. Then, by pulling back the inner sleeve 12 through the positioning protrusion 121, the inner sleeve 12 moves relative to the outer sleeve 11. While pulling back the inner sleeve 12, the spring 4 at the second end of the push rod 3 is compressed until the locking tongue 52 and the locking buckle 53 in the locking device are re-engaged to complete the locking, and the inner and outer sleeves 11 return to the initial state ready for use. The through groove 112 and the positioning protrusion 121 can also play the guiding role mentioned in the previous embodiment, and can play a role similar to that of the stepped guiding structure mentioned above.

[0061] In one embodiment, a gear fixing bracket 61 and a guide gear 62 are arranged inside the cylinder body 1. The gear fixing bracket 61 is fixed inside the cylinder body 1, and the guide gear 62 is rotatably fixed on the gear fixing bracket 61. The surface of the push rod 3 has a rack 31, and the rack 31 is arranged along the axial direction of the push rod 3. The guide gear 62 meshes with the rack 31. Through the design of the guide gear 62, the stability of the movement direction of the push rod 3 can be maintained during operation. While restricting its shaking, its movement can also be ensured to be stable. The guide gear 62 can play a role similar to a "deceleration wheel", so that the push rod 3 will not advance too fast when advancing, because if it is too fast, it may cause the reverse resistance generated by the rapid compression inside the medicine bottle 2 to affect the formation of droplets, thereby improving the atomization effect.

[0062] The gear fixing bracket 61 is fixedly connected to the outer sleeve 11 in the cylinder body 1. The gear fixing bracket 61 is arranged along the radial direction of the cylinder body 1. A clearance hole is opened on the inner sleeve 12 corresponding to the setting position of the gear fixing bracket 61. That is to say, both sides of the gear fixing bracket 61 pass through the clearance hole of the inner sleeve 12 and are fixedly connected to the inner wall of the outer sleeve 11. Such a design can prevent the gear fixing bracket 61 from interfering with the inner sleeve 12 during movement.

[0063] In another embodiment, for the setting of the guide gear 62, two or more can be set. The push rod 3 is clamped between the two guide gears 62 to improve the guiding effect and the stability of the thrust release. As shown in the figure, two guide gears 62 are arranged on the gear fixing bracket 61, and two racks 31 are arranged on the surface of the push rod 3. The two racks 31 are arranged oppositely. In this way, a guide gear 62 meshes with one of the racks 31 on the opposite sides of the push rod 3 respectively.

[0064] It can be seen that the soft mist generating driving device provided in this embodiment has a simple overall structure, low manufacturing cost, simple operation, and low usage requirements, and can meet the needs of different people. Moreover, the soft mist generating driving device of the present application forms a cylinder body through the inner and outer sleeves during operation, which can not only improve the stability during driving and propulsion, but also realize the rapid reset of the push rod on this basis.

[0065] Embodiment 4: This embodiment describes a soft mist inhaler, as Figures 8 to 18 shown, which includes a soft mist generating driving device and a medicine bottle for a soft mist inhaler as described in Embodiment 1.

[0066] Specifically, the soft mist generating driving device includes an outer sleeve 11, an inner sleeve 12, a spring 4, a push rod 3 and a spring 4; The inner sleeve 12 is disposed in the outer sleeve 11 and is slidably matched with the outer sleeve 11. The inner sleeve 12 and the outer sleeve 11 together form the cylinder body 1. The spring 4 and the push rod 3 are both disposed in the inner sleeve 12. The spring 4 is used to drive the push rod 3 to translate radially along the inner sleeve 12. The push rod 3 passes through the first end of the outer sleeve 11, and a bottle body connecting portion 111 is provided at the first end of the outer sleeve 11, and the bottle body connecting portion 111 is a threaded connecting portion or a bayonet connecting portion; A triggerable locking device 5 is provided between the outer sleeve 11 and the inner sleeve 12, and a trigger mechanism 51 of the locking device 5 is provided on the surface of the outer sleeve 11; An engaging transmission device is provided between the inner wall of the inner sleeve 12 and the outer wall surface of the push rod 3, and the engaging transmission device is used to enable the inner sleeve 12 and the push rod 3 to move in relative directions.

[0067] When in use, the medicine bottle 2 can be connected to the barrel 1 through the bottle body connecting part 111, and the end of the push rod 3 passing through the barrel 1 contacts the plunger 22 of the medicine bottle 2. At this time, the spring 4 is in a compressed state; after the trigger mechanism 51 is activated, the locking device 5 is internally disengaged and switches from a locked state to a free state. The spring 4 quickly changes from a compressed state to a free state. The spring 4 pushes the push rod 3, and the end of the push rod 3 passing through the barrel 1 pushes the plunger 22 in the barrel 1. The plunger 22 then pushes the medicine in the medicine bottle 2 to the outlet, and the atomizer chip 21 arranged at the outlet of the medicine bottle 2 further atomizes and sends the medicine out. It should be noted that when the soft mist generating driving device in the present embodiment is driving, due to the presence of the meshing transmission device, the push rod 3 moves in the direction of the medicine bottle 2, while the inner sleeve 12 moves in the opposite direction (away from the medicine bottle 2), which can play a guiding and decelerating role in the movement, and can improve the working stability of the push rod 3 during the pushing movement, so that the droplets can be stably sprayed from the outlet without obstruction; when the soft mist generating driving device in the present embodiment resets the push rod 3 after use, it only needs to push or push the inner sleeve 12 so that it moves in the direction of the medicine bottle 2, and the push rod 3 moves in the opposite direction (away from the medicine bottle 2), and the inner sleeve 12 can continuously move to transmit the force to the push rod 3 through the meshing transmission device, which is more labor-saving than the conventional method of directly applying force to the push rod 3 to reset the spring 4, simple to operate, and has low usage requirements, which can meet the needs of different groups of people.

[0068] The inner sleeve 12 is sleeved inside the outer sleeve 11, and there is a clearance fit between the inner sleeve 12 and the outer sleeve 11, so that the inner sleeve 12 can move freely in the outer sleeve 11. Additionally, a guiding or limiting structure can be provided between the outer sleeve 11 and the inner sleeve 12. For example, a stepped guiding structure can be adopted. A flange guide rail 122 is provided on the outer wall of the inner sleeve 12, and a guiding groove 113 is correspondingly provided on the outer sleeve 11. The flange guide rail 122 is clamped in the guiding groove 113. The guiding groove 113 is preferably arranged along the axial direction of the cylinder 1, so that the inner sleeve 12 can move stably in the outer sleeve 11. It should be noted that if the guiding groove 113 is provided in the form of a through groove, the flange guide rail 122 can also be used as a setting for compressing and resetting the inner sleeve 12.

[0069] In addition, in order to define the moving direction between the push rod 3 and the inner sleeve 12, a flange guide rail 32 and a guiding groove 124 as described above can also be provided between the inner sleeve 12 and the push rod 3. For example, a flange guide rail 32 is provided on the outer wall of the push rod 3, and a guiding groove 124 is correspondingly provided on the inner sleeve 12. The flange guide rail 32 on the push rod 3 is clamped in the guiding groove 124 of the inner sleeve 12. The guiding groove 124 is preferably arranged along the axial direction of the cylinder 1, so that the push rod 3 can move stably in the inner sleeve 12, prevent torsion during movement, and maintain the working stability of the push rod 3.

[0070] Specifically, in an embodiment, the outer sleeve 11 is a cylindrical tube. The outer sleeve 11 has opposite first and second ends, and the first and second ends are closed. A through hole is provided in the first end, and the first end of the push rod 3 passes through the through hole. For the convenience of description, in this embodiment, the end of the outer sleeve 11 docked with the medicine bottle 2 is defined as the first end, that is, the end of the outer sleeve 11 provided with the bottle body connecting portion 111 is the first end, and the other end of the outer sleeve 11 away from the bottle body connecting portion 111 is defined as the second end. Correspondingly, the end of the push rod 3 passing through the through hole is the first end of the push rod 3, and the other end away from it is the second end of the push rod 3. The spring 4 is arranged between the second end of the push rod 3 and the second end of the outer sleeve 11.

[0071] By closing the two ends of the hollow outer sleeve 11 to form a cavity structure, the inner sleeve 12, the push rod 3, the spring 4, etc. are all arranged in this relatively closed cavity. After being enclosed in the cavity, each component is not easily damaged, and the limiting effect of the upper and lower parts can initially limit the working stroke of the push rod 3, improving the reliability and consistency of its pushing effect.

[0072] In addition, a through hole through which the push rod 3 can pass is formed at the closed first end, and the aperture of this through hole is slightly larger than the diameter of the push rod 3. When the push rod 3 is in motion, the through hole can play a role in limiting the push rod 3, preventing it from deviating or deviating too much in the axial direction. Such a design can prevent the push rod 3 from shaking, ensuring stable force application when pushing the plunger 22 of the medicine bottle 2. This can not only ensure consistent thrust and stable atomization effect, but also avoid the reduction of the device's service life caused by the shaking of the push rod 3.

[0073] In this embodiment, the locking device 5 can be used to hold the push rod 3 in the compressed state of the spring 4, so that the push rod 3 can be in a stable state and can be quickly released after being triggered. Through the structural design of the locking device 5, the limit of the compression position of the spring 4 can be realized, the consistent reset setting of the driving force can be realized, and the control of the atomization consistency can be realized.

[0074] In one embodiment, the locking device 5 includes a trigger mechanism 51, a locking tongue 52 and a locking buckle 53. The trigger mechanism 51 is arranged on the outer sleeve 11. One of the locking tongue 52 and the locking buckle 53 is connected to the trigger mechanism 51, and the other is arranged on the inner sleeve 12. The trigger mechanism 51 is used to control the release of the fixation between the locking tongue 52 and the locking buckle 53.

[0075] It can be understood that if one of the locking tongue 52 and the locking buckle 53 is arranged on the outer sleeve 11, the other is arranged on the inner sleeve 12. The relative fixation between the outer sleeve 11 and the inner sleeve 12 can be completed by the snap connection between the locking tongue 52 and the locking buckle 53. The locking buckle 53 is usually designed as a groove or a hole for accommodating the locking tongue 52 to achieve locking. When the locking device 5 is in the locked state, the locking tongue 52 protrudes and is embedded in the locking buckle 53. In order to make the locking tongue 52 maintain a certain elastic vitality, elastic components such as the spring 4 and the damping member can be used to keep the locking tongue 52 in the locking buckle 53, which can also make the locking tongue 52 return to the proper position during reset. The trigger mechanism 51 preferably uses a button trigger. When the button is pressed, through mechanical linkage, such as a lever or a connecting rod, the locking tongue 52 can be pulled back or pushed out, so that the locking tongue 52 is disengaged from the locking buckle 53, allowing the inner sleeve 12 to be separated from the outer sleeve 11, that is, the inner and outer sleeves 11 are switched to the unlocked state. The spring 4 at the second end of the push rod 3 starts to stretch from the compressed state, pushing the push rod 3, and then pushing the plunger 22 in the medicine bottle 2 to form droplets and spray out.

[0076] In this embodiment, the locking tongue 52 on the inner sleeve 12 is made of an elastic material with certain damping characteristics. The trigger mechanism 51 (button type) presses the locking tongue 52 downward to make the locking tongue 52 away from the lock catch 53. After the locking tongue 52 is disengaged from the lock catch 53, the inner sleeve 12 and the push rod 3 can be released. The spring 4 pushes the push rod 3, and finally the plunger 22 in the medicine bottle 2 pushes the liquid medicine towards the bottle mouth to form droplets. When resetting, pulling back the locking tongue 52 can drive the inner sleeve 12 to move towards the second end of the outer sleeve 11. The push rod 3 presses the spring 4 to return to the compressed state. After the locking tongue 52 is re-engaged with the lock catch 53, the locking device 5 resumes locking, and the driving and resetting of the soft mist generating driving device can be completed.

[0077] It can be understood that in different locking devices 5 (such as different reset methods), the setting positions of the locking tongue 52 and the lock catch 53 will be slightly adjusted to ensure that it does not affect the release of the push rod 3 after release and can stably engage the locking tongue 52 and the lock catch 53 during resetting. This part should be known to those skilled in the art and will not be elaborated and described here.

[0078] In one embodiment, the meshing transmission device includes a gear fixing bracket 61 and a transmission gear 62. The gear fixing bracket 61 is fixed inside the outer sleeve 11. The transmission gear 62 is rotatably fixed on the gear fixing bracket 61. The surface of the push rod 3 has a first rack 31, and the inner side wall of the inner sleeve 12 has a second rack 123. The first rack 31 and the second rack 123 are arranged in parallel, and both the first rack 31 and the second rack 123 are arranged along the axis direction of the push rod 3. The transmission gear 62 is clamped between the first rack 31 and the second rack 123 and meshes for transmission.

[0079] Through the design of the transmission gear 62, the first rack 31 and the second rack 123, the interlocking between the inner sleeve 12 and the push rod 3 is smoother, which can maintain the stability of the movement direction of the push rod 3 during its operation. While restricting its shaking, it can also ensure its stable movement. In addition, the transmission gear 62 can play a role similar to a "speed reduction wheel", so that the push rod 3 will not advance too fast, because if it is too fast, it may cause the reverse resistance generated by the rapid compression inside the medicine bottle 2 to affect the formation of droplets. Such a design can instead improve the atomization effect.

[0080] The gear fixing bracket 61 is fixedly connected to the inner wall of the outer sleeve 11. The gear fixing bracket 61 is arranged along the radial direction of the outer sleeve 11. A clearance hole is opened on the inner sleeve 12 corresponding to the position of the gear fixing bracket 61. That is to say, both sides of the gear fixing bracket 61 pass through the clearance hole of the inner sleeve 12 and are fixedly connected to the inner wall of the outer sleeve 11. Such a design can prevent the gear fixing bracket 61 from interfering with the inner sleeve 12 during its movement.

[0081] In another embodiment, for the arrangement of the transmission gears 62, two or more than two transmission gears 62 can be arranged, with the push rod 3 clamped between the two transmission gears 62, so as to improve the guiding effect and the stability of the thrust release. Taking the arrangement of two transmission gears 62 as an example, as shown in the figure, two transmission gears 62 are arranged on the gear fixing frame 61. Two first racks 31 are arranged on the surface of the push rod 3. The two first racks 31 are oppositely arranged on both sides of the push rod 3. Correspondingly, two second racks 123 are arranged on the inner wall of the inner sleeve 12. That is to say, each first rack 31 and one second rack 123 form a group, and a transmission gear 62 is arranged between each group of the first rack 31 and the second rack 123.

[0082] For the arrangement of the reset structure, two reset schemes are provided in this embodiment. One is to pull back and reset through the protrusion on the outer side wall of the inner sleeve 12 extending out of the outer sleeve 11, and the other is to press the part of the inner sleeve 12 extending out of the end of the outer sleeve 11 to reset the inner sleeve 12. All other schemes that can realize the relative displacement of the inner sleeve 12 relative to the outer sleeve 11 should be within the protection scope of this application and will not be elaborated here.

[0083] In one embodiment, as Figures 8 to 12 shown, a through groove 112 is axially formed on the outer sleeve 11, and a positioning protrusion 121 is provided on the inner sleeve 12. The positioning protrusion 121 is clamped in the through groove 112. What this design can achieve is the restoration of locking after the locking device 5 is released and unlocked. It can be known that when the locking is released, the spring 4 extends until the inner sleeve 12 or the push rod 3 reaches the limit position, or the spring 4 basically returns to the free state, and the inner and outer sleeves 11 will maintain a relatively stable state. Then, by pulling back the inner sleeve 12 through the positioning protrusion 121, the inner sleeve 12 moves relative to the outer sleeve 11. While pulling back the inner sleeve 12, the push rod 3 moves in the reverse direction. The push rod 3 can compress the spring 4 at the second end of the push rod 3 until the locking tongue 52 in the locking device is engaged with the lock catch 53 again to complete the locking, so that the inner and outer sleeves 11 return to the initial state to be used. The through groove 112 and the positioning protrusion 121 can also play the guiding role mentioned in the previous embodiment, and the function is similar to that of the stepped guiding structure mentioned above.

[0084] In another embodiment, as Figures 13 to 18As shown, a drive cover sleeve is movably provided at the end of the second end of the outer sleeve 11. A limiting mechanism is provided between the bottom of the drive cover sleeve and the top of the second end of the outer sleeve 11. The second end of the inner sleeve 12 is fixedly connected or abutted against the drive cover sleeve. It can be understood that when the locking of the locking device 5 is released, the spring 4 extends, and under the action of the spring 4, the push rod 3 is pushed towards the first end of the outer sleeve 11. Under the action of the meshing transmission device, the inner sleeve 12 moves towards the second end of the outer sleeve 11 until the inner sleeve 12 or the push rod 3 reaches the limit position, or the spring 4 basically returns to the free state, and the inner and outer sleeves 11 will maintain a relatively stable state. When the locking device 5 locks the inner and outer sleeves 11, the drive cover sleeve is basically retracted into the outer sleeve 11. This design can avoid accidental touch and reduce the impact on the locking device 5. After the locking device 5 is unlocked, finally the drive cover sleeve protrudes from the end of the second end of the outer sleeve 11. When restoring the locking of the locking device 5, only need to press the drive end sleeve 7, so that the inner sleeve 12 moves towards the first end direction of the outer sleeve 11, and under the action of the meshing transmission device, the push rod 3 moves towards the second end of the outer sleeve 11, so that the push rod 3 compresses the spring 4 until the locking tongue 52 in the locking device 5 enters the lock catch 53 and switches to the locked state, thus completing the restoration of the soft mist generating drive device to the standby excitation state.

[0085] In addition, only by controlling the lengths of the inner sleeve 12 and the outer sleeve 11, it can be ensured that the drive end cover prevents accidental touch. For example, the length from the inner side of the first end of the outer sleeve 11 to the end of the second end of the outer sleeve 11 is L, and the length l of the inner sleeve 12 is basically equal to L. The drive cover sleeve can be fixedly connected to the second end of the inner sleeve 12. By controlling the length of the drive end sleeve 7 or the fixed position with the inner sleeve 12, the length of the drive end sleeve 7 protruding from the outer sleeve 11 can be controlled, thereby preventing accidental touch.

[0086] The soft mist generating drive device provided in this embodiment adopts a double-sleeve cylinder structure, and a meshing transmission device is arranged in the cavity of the inner sleeve. The meshing transmission device can make the inner sleeve and the push rod move in opposite directions during movement, which can not only improve the working stability of the push rod during the pushing movement, but also reduce the operation difficulty of the operator during the reset. Generally speaking, the overall structure of the soft mist generating drive device of the present application is simple, the manufacturing cost is low, the operation is simple, the use requirements are low, and it can meet the needs of different people.

[0087] In addition, the soft mist inhalation device with the soft mist generating drive device of the present application can be adapted to medicine bottles of different specifications and different components, can better meet the needs of users, can realize the reuse of the soft mist generating drive device, and save the use cost of users.

[0088] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
