[0037] Nebulizer inhalation therapy uses a nebulizer device to disperse the drug into tiny droplets or particles, suspending them in the gas and allowing them to enter the respiratory tract and lungs as the human body breathes, thereby achieving the purpose of cleaning the airways, humidifying the airways, and providing local and systemic treatment.

[0038] The main equipment for nebulization inhalation therapy is a nebulizer, which is usually equipped with a medicine cup. There are many types of nebulizers, including portable nebulizers. In order to achieve ultimate portability, portable nebulizers usually have a smaller mouth of the medicine cup. Users need to inject liquid medicine into the medicine cup before using the nebulizer. However, a medicine cup with a too small mouth makes it difficult for users to inject liquid, and it is easy for the liquid medicine to spill to the outside of the medicine cup due to hand shaking, affecting the user's experience.

[0039] In view of this, the utility model proposes a nebulizer medicine cup structure and a portable nebulizer, aiming to alleviate the problem that the medicine cup of the existing portable nebulizer has a small mouth, which makes it difficult for users to inject liquid. Figure 1 A schematic structural diagram of an embodiment of a portable atomizer provided by the utility model; Figure 2 Based Figure 1 A schematic structural diagram of a medicine cup structure of a nebulizer when the medicine cup cover is in an open state; Figure 3 for Figure 2 A schematic diagram of a top view of a medicine cup structure of a nebulizer; Figure 4 for Figure 2 A schematic diagram of the structure of the nebulizer medicine cup structure when the driving part is in a gathered position.

[0040] See also Figures 1 to 4 In one embodiment of the utility model, the nebulizer medicine cup structure 100 includes a medicine cup body 1, a flexible expansion sleeve 2 and a driving assembly 3. The medicine cup body 1 has a medicine liquid chamber 11 opened along the axial direction. One end of the flexible expansion sleeve 2 is arranged on the medicine cup body 1 and connected to the medicine liquid chamber 11, and the other end is arranged to expand away from the medicine cup body 1 along the axial direction. The driving assembly 3 includes a plurality of driving parts 31. The plurality of driving parts 31 are arranged on the flexible expansion sleeve 2 along the circumference of the medicine liquid chamber 11, and one end is flipped and arranged on the medicine cup body 1. The plurality of driving parts 31 have a gathering position within their flipping stroke to drive the flexible expansion sleeve 2 to gather and cover the medicine liquid chamber 11.

[0041] It should be noted that the liquid medicine cavity 11 of the medicine cup body 1 is used to inject liquid medicine, and its specific shape can be round or square, which is not limited in this embodiment; the flexible expansion sleeve 2 is usually a thin-walled sleeve structure, which is hollow in the middle and has two openings, one large and one small, at both ends. For example, the flexible expansion sleeve 2 can be a trumpet-shaped structure. The material of the flexible expansion sleeve 2 is flexible, which means that it can be deformed. Therefore, it can gather the larger opening end under the drive of multiple driving parts 31, so as to achieve the purpose of covering the liquid medicine cavity 11; multiple driving parts 31 can be used to drive the medicine cup body 11 to form a hollow space, and the flexible expansion sleeve 2 can be used to form a trumpet-shaped structure. One end of the driving portion 31 is flipped and set on the medicine cup body 1, which can be understood as the driving portion 31 is hingedly connected to the medicine cup body 1, and the hinge axes of each driving portion 31 are respectively in different radial directions. It can be understood that the hinge axes of the driving portion 31 are tangent to the cup edge of the medicine cup body 1. When in the gathered position, multiple driving portions 31 are all in the opening plane of the medicine liquid chamber 11, thereby driving the flexible expansion sleeve 2 to cover the medicine liquid chamber 11. The specific structural shapes of the driving portion 31 are various, for example, it can be rod-shaped or plate-shaped, and this embodiment is not limited to this.

[0042] In the technical solution of the present utility model, when it is necessary to inject medicine into the medicine chamber 11, the flexible expansion sleeve 2 can be driven to the expanded state by the driving part 31, and the user can inject medicine through the larger opening end of the flexible expansion sleeve 2. The flexible expansion sleeve 2 can guide the medicine into the medicine chamber 11. The larger opening end of the flexible expansion sleeve 2 provides a larger injection space than the opening of the medicine chamber 11, which alleviates the situation where the user spills the medicine out of the medicine cup during the injection process, and reduces the difficulty of the user injecting medicine into the medicine chamber 11. At the same time, the multiple driving parts 31 can also cooperate to move to the gathered position in a unified manner, so as to drive the flexible expansion sleeve 2 to shrink and cover the medicine chamber 11, thereby preventing the medicine from overflowing, and at the same time achieving the purpose of storing the flexible expansion sleeve 2, thereby ensuring the compactness and portability of the nebulizer medicine cup structure 100.

[0043] In some embodiments, the nebulizer medicine cup structure 100 further includes a medicine cup cover 4, one end of which is flipped and disposed on the medicine cup body 1 and outside the flexible expansion sleeve 2. The medicine cup cover 4 can seal the medicine liquid cavity 11 within its flipping stroke.

[0044] It should be noted that one end of the medicine cup cover 4 is flipped and set on the medicine cup body 1, which can be understood as the medicine cup cover 4 is hingedly connected to the medicine cup body 1, and the medicine cup cover 4 is located on the outside of the flexible expansion sleeve 2, which means that the medicine cup cover 4 can cover the flexible expansion sleeve 2 and multiple driving parts 31 while sealing the medicine liquid cavity 11.

[0045] According to the above technical solution, the medicine cup cover 4 is flipped to ensure complete sealing of the medicine liquid cavity 11 to prevent the medicine liquid from overflowing, and at the same time completely cover the flexible expansion sleeve 2 in the contracted state, thereby improving the aesthetics of the nebulizer medicine cup structure 100.

[0046] In some embodiments, multiple driving parts 31 also have an expansion position within their flipping stroke to drive the flexible expansion sleeve 2 to expand and expose the medicine liquid cavity 11; a pushing part 32 is formed on the medicine cup cover body 4, and the pushing part 32 is arranged in alignment with one of the driving parts 31. Within the moving stroke of the medicine cup cover body 4 to cover the medicine liquid cavity 11, the pushing part 32 can push the driving part 31 from the expansion position to the gathering position, so as to drive other pushing parts 32 to move to the gathering position successively through the flexible expansion sleeve 2.

[0047] It should be noted that the pushing portion 32 pushes the driving portion 31 to move from the expanded position to the gathered position, so as to drive other pushing portions 32 to move to the gathered position successively through the flexible expansion sleeve 2. This means that since multiple driving portions 31 are arranged on the flexible expansion sleeve 2, the driving portion 31 can actively flip over to drive the flexible expansion sleeve 2 to expand or contract, and the traction force applied to each driving portion 31 by the flexible expansion sleeve 2 can also drive multiple driving portions 31 to move in the reverse direction. It can be understood that the flexible expansion sleeve 2 can only pull the driving portion 31 to move from the expanded position to the gathered position.

[0048] According to the above technical scheme, through the push of the pushing portion 32 on the medicine cup cover 4, the corresponding driving portion 31 can first leave the expanded position, thereby pulling the corresponding partial structure of the flexible expansion sleeve 2 together, and the partial structure of the flexible expansion sleeve 2 then drives the other two adjacent driving portions 31 to move toward the gathered position. Under the sequential transmission of the gathering force, the driving portion 31 farthest from the pushing portion 32 is finally responded to, thereby moving toward the gathered position. Although the farthest driving portion 31 cannot be pulled to the gathered position by the flexible expansion sleeve 2, the medicine cup cover 4 can be flipped to the top of the farthest driving portion 31 at this time, so that the driving portion 31 is pressed to the gathered position through the medicine cup cover 4. In the technical scheme, through the linkage effect of the medicine cup cover 4, multiple driving portions 31 and the flexible expansion portion sleeve, after the injection is completed, it is only necessary to manually push the medicine cup cover 4 to flip to the capping medicine liquid cavity 11, and multiple driving portions 31 can return to the gathered position autonomously, reducing the difficulty for users to gather and fold the flexible expansion sleeve 2.

[0049] In some embodiments, multiple driving parts 31 also have an expansion position within their flipping stroke to drive the flexible expansion sleeve 2 to expand and expose the medicine liquid cavity 11; a reset structure 5 is arranged between one end of the driving part 31 and the medicine cup body 1, and the reset structure 5 can drive the driving part 31 to move toward the expansion position.

[0050] It should be noted that the function of the reset structure 5 is to apply a force to the drive part 31 toward the expanded position, so that after the external force withdraws from the drive part 31, the drive part 31 can reset to the expanded position autonomously. There are many specific types of the reset structure 5, for example, it may include a rubber elastic structure. This embodiment does not limit the specific type of the reset structure 5.

[0051] According to the above technical solution, before injecting liquid into the medicine liquid chamber 11, the user will first open the medicine liquid cover. The force of the medicine liquid cover acting on the driving part 31 disappears, and the driving part 31 can actively reset to the expanded position under the resetting action of the resetting structure 5, thereby actively unfolding the flexible expansion structure to wait for the user to inject liquid, thereby improving the user experience.

[0052] Specifically, in some embodiments, the reset structure 5 includes a reset coil spring, one end of which is abutted against the medicine cup body, and the other end of which is abutted against the driving part 31 .

[0053] It should be noted that the above embodiment has explained that the medicine cup cover 4 is hingedly connected to the medicine cup body 1. The reset coil spring in this embodiment is set at the hinge axis of the medicine cup cover 4 and the medicine cup body 1. The specific setting form is not repeated in this embodiment.

[0054] According to the above technical solution, by setting the reset coil spring, it is possible to achieve minimum occupation of the space on the medicine cup body 1 while meeting the reset requirement, which is in line with the design concept of the portable nebulizer 1000.

[0055] See also Figures 2 to 4 In some embodiments, a locking portion 12 is formed on the medicine cup body 1 ; a buckling portion 421 is formed on the medicine cup cover 4 , and when the medicine cup cover 4 is sealed to the medicine liquid cavity 11 , the buckling portion 421 can be buckled into the locking portion 12 .

[0056] It should be noted that there are many specific types of the buckling portion 421 and the locking portion 12, which are not limited in this embodiment. After the buckling portion 421 is buckled into the locking portion 12, the two can achieve a connection that overcomes a certain amount of force, which is sufficient to ensure that the medicine cup cover body 4 remains in a sealed state with the medicine cup body without the action of unexpected forces, and under the action of intentional external forces, the buckling portion 421 can also be separated from the locking portion 12.

[0057] According to the above technical solution, the locking portion 12 is simply fastened to the fastening portion 421 to ensure a stable sealing state between the medicine cup cover 4 and the medicine cup body, thereby reducing the probability of the medicine cup cover 4 being separated from the medicine cup body and causing the medicine liquid to spill.

[0058] In some embodiments, the medicine cup cover 4 has a hinged end 41 and a flip end 42 which are radially opposite to each other. The hinged end 41 is hingedly disposed on the medicine cup body 1 ; and the buckle portion 421 is disposed on the flip end 42 .

[0059] It should be noted that the buckle part 421 and the locking part 12 are arranged in a counterpositioned manner, and the buckle part 421 can be arranged in many positions on the medicine cup cover 4, as long as a torque for sealing the medicine cup cover 4 to the medicine cup body 1 can be applied to the medicine cup cover 4.

[0060] According to the above technical solution, the buckle part 421 is arranged at the flip end 42 of the medicine cup cover 4. According to the lever principle, the torque required to drive the buckle part 421 out of the locking part 12 is the largest at this time, which further ensures the sealing stability of the medicine cup cover 4.

[0061] The simple sealing setting of the medicine cup cover 4 is more effective for sealing the liquid medicine cavity 11, but the liquid medicine may still overflow from the sealing gap between the medicine cup cover 4 and the medicine cup body. In view of this, in some embodiments, a sealing groove 13 is formed on the medicine cup body 1 around the liquid medicine cavity 11; a sealing protrusion 43 is formed on the medicine cup cover 4 corresponding to the sealing groove 13, and when the medicine cup cover 4 is sealed to the liquid medicine cavity 11, the sealing protrusion 43 can be pressed into the sealing groove 13. According to the above technical solution, the length of the path for the liquid medicine to overflow from the liquid medicine cavity 11 is increased by the pressing setting of the sealing protrusion 43 and the sealing groove 13, that is, the probability of the liquid medicine overflowing is reduced.

[0062] See also Figure 3 In some embodiments, a sealing gasket 5 is disposed in the sealing groove 13 .

[0063] The function of the sealing gasket 5 is to enhance the sealing effect between the sealing protrusion 43 and the sealing groove 13 to prevent the liquid medicine chamber 11 from exchanging gases with the external atmosphere. The sealing gasket 5 can be made of many specific materials. For example, the sealing gasket 5 can be made of rubber or wood. The specific material of the sealing gasket 5 is not limited in this embodiment.

[0064] According to the above technical solution, by setting the sealing gasket 5, the sealing gap generated after the sealing protrusion 43 and the sealing groove 13 are pressed together can be reduced, thereby enhancing the sealing effect, preventing the medicine in the medicine chamber 11 from overflowing to the outside of the medicine cup body 1, and further improving the user experience.

[0065] To achieve the above-mentioned purpose, the portable nebulizer 1000 proposed in the present invention includes a nebulizer medicine cup structure 100. The specific structure of the nebulizer medicine cup structure 100 refers to the above-mentioned embodiment. Since the portable nebulizer 1000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
