[0024] ​Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] like Figures 1-4 As shown, this application provides an atomization system 100, including an atomizing device 10, a liquid medicine pack 20, a sealing connector 30, and a mouthpiece 40.

[0026] Please combine Figure 5 To understand, the atomizing device 10 includes an atomizing unit 11, a battery cell 12, and a circuit 13.

[0027] The atomizing unit 11 is used to atomize the liquid medicine. In this example, the atomizing unit 11 includes an ultrasonic atomizing plate, which uses a piezoelectric element to generate high-frequency vibrations to atomize the liquid medicine in the micropores of the substrate into a liquid mist, which is then sprayed out from the micropores for inhalation by the user. The specific structure of the ultrasonic atomizing plate can be found in the prior art and will not be described in detail here.

[0028] The battery cell 12 provides power for operating the atomizing unit 11. The battery cell 12 can be a rechargeable battery cell or a disposable battery cell.

[0029] Circuit 13 can control the overall operation of atomizing unit 11. Circuit 13 not only controls the operation of battery cell 12 and atomizing unit 11, but also controls the operation of other components in ultrasonic atomizing system 100. One end of button K is exposed on atomizing device 10, and the other end is electrically connected to circuit 13; circuit 13 can receive commands from button K to control the overall operation of atomizing unit 11.

[0030] The atomizing device 10 also includes a receiving chamber 14 that is in fluid communication with the atomizing unit 11, and a puncturing component 15 is disposed in the receiving chamber 14. In this example, the puncturing component 15 is a rotary puncturing component.

[0031] The medicine solution package 20 is used to store the medicine solution. In a preferred embodiment, the medicine solution package 20 is a disposable medicine solution package.

[0032] Specifically, please combine Figures 6-8 To understand this, the liquid medicine package 20 includes an encapsulation film 21 and a shell 22.

[0033] The shell 22 is roughly cylindrical, with a hollow interior forming a liquid storage chamber 22a. The volume of the liquid storage chamber 22a is between 0.25 ml and 5 ml, which ensures that the liquid stored in the medicine package 20 is a standard quantitative quantity, such as 0.5 ml, 1 ml, 2 ml, 3 ml, 4 ml, etc.

[0034] The housing 22 has a connecting portion (not shown in the attached drawings) for detachable connection with the atomizing device 10. The connecting portion can be a threaded structure in a threaded connection mechanism, through which a threaded connection with the receiving chamber 14 is achieved; of course, a snap-fit ​​connection mechanism or a screw-fit connection mechanism is also feasible. Furthermore, the connecting portion can also be a groove or protrusion structure in a positioning mechanism with a convex-concave fit (similar to the structural design of a pen cap), so that when the liquid packet 20 is received in the receiving chamber 14, feedback information indicating that it has been inserted into place can be received.

[0035] A groove 22b is formed on the outer surface of the sidewall of the housing 22, and the sealing connector 30 is sleeved on the outer surface of the sidewall of the housing 22 and partially housed within the groove 22b. Thus, when the liquid medicine package 20 is received in the receiving chamber 14 through the opening A, the sealing connector 30 seals the gap between the inner surface of the receiving chamber 14 and the outer surface of the liquid medicine package 20 to prevent backflow of the liquid medicine from the opening A; simultaneously, the liquid medicine package 20 can be connected to the receiving chamber 14 through an interference fit with the sealing connector 30.

[0036] To facilitate observation of the liquid medicine stored in the storage chamber 22a, the top wall 22c of the shell 22 is at least partially made of transparent material to form a viewing window; thus, the liquid medicine can be observed through the viewing window.

[0037] When the liquid medicine packet 20 is received in the receiving chamber 14, the top wall 22c of the housing 22 is exposed outside the housing of the atomizing device 10, while the rest of the housing 22 is contained within the receiving chamber 14. The top wall 22c of the housing 22 also has a radially extending portion 22d, which forms at least a partial extraction site to facilitate the user's extraction of the liquid medicine packet 20. Figure 2 As shown, in a preferred embodiment, the end of the opening A is lower than the top wall 22c of the housing 22, so that the portion of the housing 22 located between the top wall 22c of the housing 22 and the end of the opening A is exposed outside the housing of the atomizing device 10, that is, the radially extending portion 22d is exposed outside the opening A; in this way, the user's fingers can easily grasp the radially extending portion 22d and remove the liquid packet 20 from the receiving chamber 14.

[0038] The top wall 22c of the housing 22 has an upward protruding part, which makes the shape of the housing 22 consistent with that of the housing of the atomizing device 10, resulting in better aesthetics.

[0039] In this example, the housing 22 does not have a bottom wall, thus forming an opening 22e; the opening 22e is in fluid communication with the liquid storage chamber 22a. It is easy to imagine that the housing 22 could have a bottom wall, with the opening 22e formed through a through hole in the bottom wall, which would also be feasible.

[0040] The encapsulation film 21 is combined on the side wall of the shell 22 to seal the opening 22e, thereby avoiding the medicine in the storage cavity 22a from being contaminated. The encapsulation film 21 is made of easily-pierced materials such as aluminum foil or tin foil, so that the bottom of the medicine bag 20 constitutes an easily-pierced part. When the medicine bag 20 is received in the receiving chamber 14 through the opening A, the piercing member 15 can pierce the bottom of the medicine bag 20; in this way, the medicine can flow from the sealed medicine bag 20 into the receiving chamber 14, and then into the atomization unit 11.

[0041] A protrusion 22f is formed on the inner surface of the side wall of the shell 22, and one end of the protrusion 22f extends to the bottom end of the shell 22. The protrusion 22f can function as a reinforcing rib, and one end of the protrusion 22f can form an abutting part that abuts against one end of the rotating piercing member 15 when the medicine bag 20 is received in the receiving chamber 14 through the opening A, so as to drive the other end of the rotating piercing member 15 to rotate by a preset angle and pierce the bottom of the medicine bag 20. The length of the opening 22e of the shell 22 should be greater than the length of the other end of the rotating piercing member 15, so as to avoid the rotating piercing member 15 failing to pierce the bottom of the medicine bag 20. Generally, the length of the opening 22e is between 6.5 mm and 20 mm.

[0042] Please understand that Figure 9 In another preferred embodiment, the shell 22 is configured to project a front view that is left-right symmetrical on a basic projection plane, and the dashed line in the figure is the axis of symmetry of the front view. In this way, the medicine bag 20 can be removably received in the receiving chamber 14 through the opening A after being horizontally rotated by 180°; that is, the medicine bag 20 can be inserted into the atomization device 10 without distinguishing the left and right directions.

[0043] The cross section of the shell 22 is one of a circle, an ellipse, a track ring, a square, and a rectangle. In the present example, the ellipse is preferred. The protrusion 22f can be arranged on one side of the ellipse, and the opening 22e can be arranged on the other side of the ellipse. In a preferred embodiment, the protrusions 22f are symmetrically arranged on the two sides of the shell 22 in the horizontal direction (on the major axis of the ellipse); in this way, the medicine bag 20 can be inserted into the atomization device 10 without distinguishing the left and right directions, and one end of each of the protrusions 22f can abut against one end of the rotating piercing member 15 after the medicine bag 20 is horizontally rotated by 180°.

[0044] The mouthpiece 40 is arranged at the opening B of the atomization device 10, and the airflow inlet is arranged on the mouthpiece 40. In this way, when the medicine bag 20 is received in the receiving chamber 14 through the opening A, the user can operate the button K to make the circuit 13 control the atomization unit 11 to start atomization, the liquid mist formed by atomization is sprayed out of the opening B of the atomization device 10, mixed with the gas flowing into the airflow inlet of the mouthpiece 40, and then sprayed out of the mouth end of the mouthpiece 40, so as to be inhaled by the user (see Fig. 2). Figure 3by the dashed arrow in FIG. 4.

[0045] It can be appreciated that the mouthpiece 40 can be replaced by other accessories, such as a face mask, etc.

[0046] It should be noted that the preferred embodiments of the present application are shown in the description and drawings of the present application, but the present application can be implemented in many different forms, and is not limited to the embodiments described in the specification. These embodiments are not additional limitations on the content of the present application, and the purpose of providing these embodiments is to make the understanding of the disclosed content of the present application more thorough and comprehensive. Furthermore, the above technical features continue to combine with each other to form various embodiments not listed above, which are considered to be within the scope of the present application. Furthermore, for those skilled in the art, the above description can be improved or transformed, and all these improvements and transformations should be within the protection scope of the claims of the present application.
