[0021] In the present disclosure, unless otherwise specified, the use of the terms "first", "second", and the like to describe various elements is not intended to limit the positional relationship, time sequence relationship or importance relationship of these elements. Such terms are only used to distinguish one element from another element. In some examples, the first element and the second element can refer to the same instance of the element, and in some cases, based on the context of the description, they can also refer to different instances.

[0022] The terminology used in the description of the various described examples within the present disclosure is intended to be interpreted in only a descriptive sense, and is not intended to be limiting. So long as the context does not otherwise require, whenever a singular form is used herein, it will be understood that the plural is included. As used herein, the term "plurality" means two or more, and the term "based on" is to be interpreted as "based, at least in part, on." Furthermore, the terms "and / or" and "at least one of" encompass any and all possible combinations of the listed items.

[0023] Within the scope of the present disclosure, "nebulizer" refers to a device for nebulizing a liquid. Typically, a nebulizer is used to nebulize a fluid (e.g., a medicament or similar fluid) and to eject the nebulized fluid to the mouth or nose of a user (e.g., a patient).

[0024] In the related art, a predetermined dose of liquid to be ejected can be loaded before the liquid is ejected, and then the loaded predetermined dose of liquid is ejected. However, the loading process is often not smooth and stable, resulting in loading jamming or post-loading mis-ejection.

[0025] In view of this, the present disclosure proposes a loading assembly for a nebulizer and a nebulizer. Within the scope of the present disclosure, the loading assembly can be installed into the nebulizer and can be associated with a push switch and / or a rotary switch of the nebulizer. Here, the loading assembly proposed by the present disclosure includes an actuator, a first component including a first helical end face, and a second component including a helical section having a second helical end face for cooperating with the first helical end face and a horizontal section adjacent to the helical section. The first component and the second component are configured such that the second component is movable away from the first component to a pre-loading position in the case where the second component is rotated in a first direction relative to the first component along the cooperating first helical end face and second helical end face, and the actuator is configured to carry the horizontal section to block the second component from leaving the pre-loading position in the case where the second component is moved to the pre-loading position. On the one hand, since the helical section of the second component has the second helical end face for cooperating with the first helical end face, the second component and the first component are movable away from each other to the pre-loading position in the case where they are relatively rotated along the cooperating first helical end face and second helical end face, thereby smoothly loading the liquid. On the other hand, since the second component has the horizontal section adjacent to the helical section, the horizontal section of the second component is stably carried on the actuator after smoothly transitioning from the loading process to the position where the loading is completed (i.e., the pre-loading position), thereby preventing an undesirable disengagement between the second component and the actuator, thereby preventing mis-ejection.

[0026] The loading assembly according to exemplary embodiments will be described below with reference to FIGS. 1 to 6. Among them, FIG. 1 is a schematic view illustrating a loading assembly for an atomizer in a trigger position state according to exemplary embodiments; FIG. 2 is a schematic view illustrating a loading assembly for an atomizer in an intermediate state according to exemplary embodiments; FIG. 3 is a schematic view illustrating a loading assembly for an atomizer in a pre-loading position state according to exemplary embodiments. In addition, FIG. 4 is a schematic view illustrating a first component of a loading assembly for an atomizer according to exemplary embodiments; FIGS. 5 and 6 are schematic views illustrating a second component of a loading assembly for an atomizer according to exemplary embodiments.

[0027] In the context of the present disclosure, the "pre-loading position" of the loading assembly can refer to a position in which a liquid in the atomizer is loaded to be ready to be ejected (e.g., from the tank to the pumping chamber), in which position the atomizer cannot autonomously perform an atomization ejection without a triggering action of an external force, and only when the loading assembly is triggered, for example, by a human operation (e.g., pressing), the loading assembly can be restored from the "pre-loading position" to the "trigger position", i.e., the liquid in the atomizer is converted from a state of being loaded to be pre-ejected to a state of being atomized and ejected. In the "trigger position", the atomizer can be operated again (e.g., screwed) to be converted to the "pre-loading position", and thus the "trigger position" can also be referred to as the initial position.

[0028] First, referring to FIGS. 1 to 3, the loading assembly 1000 for an atomizer includes a first component 1010, a second component 1020, and an actuator 1030.

[0029] As can be seen, the second component 1020 in FIG. 1 is in the trigger position (also the initial position), the second component 1020 in FIG. 3 is in the pre-loading position, and the second component 1020 in FIG. 2 is in an intermediate state between the trigger position and the pre-loading position. In an example, in the case of the pre-loading position, the drug liquid can be pumped from the tank to the pumping chamber located at the first component 1010 or the second component 1020; in the case of transitioning from the pre-loading position to the trigger position, the drug liquid can be ejected from the pumping chamber through the nozzle, and accordingly, after the ejection is completed, the second component 1020 in the trigger position is in the initial position of the next action cycle, so as to be moved to the pre-loading position again.

[0030] Referring to FIG. 4, the first component 1010 includes a first fitting portion 1011 having a first helical end face 1012. As can be seen from FIG. 4, the first fitting portion 1011 can extend helically upward from a bottom position of the body of the first component 1010 to a top position, and accordingly, the helically extending first fitting portion 1011 forms the first helical end face 1012.

[0031] Referring to FIGS. 5 and 6, the second component 1020 includes a second mating portion 1021, which includes a helical section 1022 and a horizontal section 1023. Among others, the helical section 1022 has a second helical end face 1024 for mating with the first helical end face 1012 of the first mating portion 1011. The horizontal section 1023 is adjacent to the helical section 1022.

[0032] The first component 1010 and the second component 1020 are configured such that the second component 1020 is movable away from the first component 1010 to a pre-loaded position in a case where the second component 1020 is rotated relative to the first component 1010 along the mating first helical end face 1012 and second helical end face 1024 towards the first direction D1. For example, referring to FIGS. 1 to 3, starting from the position shown in FIG. 1, the second component 1020 is rotated relative to the first component 1010 towards the clockwise direction in FIG. 1, and as the second component 1020 is rotated, the second component 1020 gradually moves away from the first component 1010 as shown in FIG. 2; when the second component 1020 is further rotated towards the clockwise direction, the second component 1020 moves to the pre-loaded position shown in FIG. 3. It will be appreciated that the movement of the second component 1020 away from the first component 1010 to the pre-loaded position can be that the first component 1010 is stationary while the second component 1020 moves; or that the second component 1020 is stationary while the first component 1010 moves.

[0033] The actuator 1030 is configured to carry the horizontal section 1023 (e.g., the horizontal end face 1025 of the horizontal section 1023) to block the second component 1020 from leaving the pre-loaded position in a case where the second component 1020 moves to the pre-loaded position.

[0034] Thus, on one hand, since the helical section 1022 of the second component 1020 has the second helical end face 1024 for mating with the first helical end face 1012, the first component 1010 and the second component 1020 are movable away from each other to the pre-loaded position along the mating first helical end face 1012 and second helical end face 1024 when the second component 1020 is rotated relative to the first component 1010, thereby smoothly loading the liquid; on the other hand, since the second component 1020 has the horizontal section 1023 adjacent to the helical section 1022, the second component 1020 is stably carried on the actuator 1030 after a smooth transition from the loading process to the position where the loading is completed (i.e., the pre-loaded position), thereby preventing an undesired disengagement between the second component 1020 and the actuator 1030, thereby preventing a mis-firing.

[0035] In some embodiments, as shown in FIG. 3, the actuator 1030 can include a limit protrusion 1031 for blocking the rotation of the second component 1020 towards the first direction D1 in the preloaded position. And as shown in FIG. 5, the helical section 1022 includes a first sub-section 1026 and a second sub-section 1027 located between the first sub-section 1026 and the horizontal section 1023, and the second sub-section 1027 is provided with a recess 1028 for accommodating the limit protrusion 1031 of the actuator 1030. By further providing the recess 1028 for accommodating the limit protrusion 1031 of the actuator 1030 in the helical section 1022, on the one hand, the undesired rotation between the second component 1020 and the first component 1010 towards the first direction D1 can be prevented in a simple structure, and the limit protrusion 1031 is accommodated into the recess 1028 without occupying additional space; on the other hand, such a configuration does not affect the horizontal section 1023, and thus does not affect the stable bearing of the actuator 1030 on the second component 1020.

[0036] In some embodiments, continuing to refer to FIG. 5, the recess 1028 in the second sub-section 1027 is recessed downward from the second helical end surface 1024 of the second sub-section 1027. For example, the recess 1028 can be formed in a material-removing manner (e.g., machining, laser processing or etching) on the basis of the entire second helical end surface 1024 of the second sub-section 1027. In this way, not only is the processing of the recess 1028 facilitated, but the shape of the recess 1028 can also be flexibly adjusted according to the shape of the protrusion 1031.

[0037] In some embodiments, as shown in FIG. 5 and FIG. 6, the second helical end surface 1024 of the second sub-section 1027 is in the same helical surface as the second helical end surface 1024 of the first sub-section 1026. In this way, even with the presence of the recess 1028, when the second component 1020 rotates relative to the first component 1010 towards the first direction D1 along the cooperated first helical end surface 1012 and the second helical end surface 1024, the rotation process can still be smoothly carried out without jerking or jamming due to the second helical end surface 1024 of the second sub-section 1027 being in the same helical surface as the second helical end surface 1024 of the first sub-section 1026, thereby further improving the user experience.

[0038] In some embodiments, with reference to FIGS. 3 and 5, the actuator 1030 can be disposed partially around the first component 1010 and / or the second component 1020, the actuator 1030 can include a bearing surface 1032 for bearing the horizontal section 1023, and the limit protrusion 1031 is located radially inside the bearing surface 1032. And the recess 1028 in the second sub-section 1027 is located radially outside the second component 1020. For example, the actuator 1030 can be connected with the first component 1010 and disposed partially around the outer periphery of the first mating portion 1011; or, the actuator 1030 can be connected with the second component 1020 and disposed partially around the outer periphery of the second mating portion 1021; or, the actuator 1030 can be connected with both the first component 1010 and the second component 1020 and disposed partially around both the first mating portion 1011 and the second mating portion 1021. For example, the main body of the actuator 1030 can have a substantially annular shape, so that the inner periphery thereof can substantially surround the first component 1010 or the second component 1020 having a substantially cylindrical outer surface. Since the limit protrusion 1031 is located radially inside the bearing surface 1032, and the recess 1028 in the second sub-section 1027 is located radially outside the second component 1020, the limit protrusion 1031 disposed around the first component 1010 or the second component 1020 can smoothly enter the recess 1028 in the second sub-section 1027, thereby reducing jamming.

[0039] In some embodiments, the actuator 1030 can be configured in the shape of a curved arm, the curved arm is disposed around the first component 1010 and / or the second component 1020, and the curved arm can be configured such that when the bearing surface 1032 of the curved arm contacts the horizontal section 1023 of the second component 1020, the limit protrusion 1031 of the curved arm enters the recess 1028 in the second sub-section 1027. In an example, a pair of rotationally symmetrical second components 1020 can be provided, and accordingly, left and right curved arms are provided, so that the loading process is more stable.

[0040] In some embodiments, with reference to FIG. 5, the horizontal section 1023 has a horizontal end surface 1025, and the second helical end surface 1024 of the second sub-section 1027 smoothly transitions with the horizontal end surface 1025 of the horizontal section 1023. Thus, when the first helical end surface 1012 slides along the second helical end surface 1024 of the second sub-section 1027, it can smoothly transition to the horizontal end surface 1025 of the horizontal section 1023, thereby further reducing jamming. In an example, there can be a chamfer between the second helical end surface 1024 of the second sub-section 1027 and the horizontal end surface 1025 of the horizontal section 1023.

[0041] In some embodiments, the bottom surface of the recess 1028 of the second sub-section 1027 is smoothly transitioned with the second helical end surface 1024 of the first sub-section 1026. Thereby, when the limit protrusion 1031 of the actuator 1030 enters the recess 1028, it can be more smooth to reduce the jam. In an example, there can be a chamfer between the bottom surface of the recess 1028 of the second sub-section 1027 and the second helical end surface 1024 of the first sub-section 1026.

[0042] In some embodiments, the recess 1028 of the second sub-section 1027 can be such that the second helical end surface 1024 of the second sub-section 1027 is discontinuous with the second helical end surface 1024 of the first sub-section 1026. As shown in FIG. 5, at least at a portion of the helical section 1022, the second helical end surface 1024 can be discontinuous, which allows to provide a large enough recess 1028 to accommodate the limit protrusion 1031 of the actuator 1030 within the limited space of the second mating portion 1021 of the second component 1020, without affecting the smooth sliding of the first helical end surface 1012 over the second helical end surface 1024. For example, at the same time, the first helical end surface 1012 slides over at least one of the second helical end surface 1024 of the second sub-section 1027 or the second helical end surface 1024 of the first sub-section 1026.

[0043] In some embodiments, as shown in FIG. 5, the second component 1020 includes a second mating portion 1021, over which the helical section 1022 and the horizontal section 1023 described above are located, the horizontal section 1023 has a horizontal end surface 1025, in the second mating portion 1021, the horizontal end surface 1025 is farthest away from the body of the second component 1020, and the second helical end surface 1024 of the helical section 1022 gradually decreases in distance from the body of the second component 1020 as the helical section 1022 moves away from the horizontal section 1023.

[0044] In some embodiments, with continued reference to FIG. 5, the second component 1020 can further include a reinforcing section 1029 extending from the body of the second component 1020 and connected with the helical section 1022. Thereby, by providing the reinforcing section 1029 connected with the helical section 1022, the structural strength of the helical section 1022 can be reinforced, so that the second component 1020, especially the second mating portion 1021 of the second component 1020, is more stable as a whole.

[0045] In some embodiments, with continued reference to FIGS. 5 and 6, the reinforcing section 1029 can have a third helical end face 1129, and a step 1130 can be provided between the third helical end face 1129 and the second helical end face 1024 of the helical section 1022, such that the first helical end face 1012 is not in contact with the third helical end face 1129 when the first helical end face 1012 cooperates with the second helical end face 1024. For example, the helical surface on which the third helical end face 1129 is located can be lower in its entirety than the helical surface on which the second helical end face 1024 is located, so that the structural reinforcing effect of the reinforcing section 1029 is taken into account, and the third helical end face 1129 of the reinforcing section 1029 does not come into contact with the first helical end face 1012 to cause unnecessary frictional resistance, thereby ensuring smoother loading.

[0046] In some embodiments, the loading assembly 1000 can further include an elastic member (not shown in the figures) configured to store energy when the second component 1020 moves away from the first component 1010, and the actuator 1030 can be configured to release the second component 1020 when triggered, so that the second component 1020 moves toward the first component 1010 to the triggered position under the action of the elastic member. In examples, the elastic member can be a spring or other elastic member, as long as it can store energy through elastic deformation. In examples, the elastic member (e.g., a spring) can be arranged on the side of the second component 1020 close to the first component 1010, and stretch to store energy when the second component 1020 moves away from the first component 1010, and when the elastic member rebounds, it can push the second component 1020 to the triggered position through the pulling force; in addition, the elastic member (e.g., a spring) can be arranged on the side of the second component 1020 away from the first component 1010, and compress to store energy when the second component 1020 moves away from the first component 1010, and when the elastic member rebounds, it can push the second component 1020 to the triggered position through the pushing force.

[0047] In some embodiments, as shown in FIG. 5, the circumferential edge of the second component 1020 can be provided with at least one positioning guide 1200. The positioning guide 1200 can be used to position and guide the second component 1020 when it is mounted to other components.

[0048] A second aspect of the present disclosure provides an atomizer.

[0049] The atomizer of the present disclosure will be further described below in conjunction with FIGS. 7-9. FIG. 7 is a perspective view illustrating an atomizer according to an example embodiment; FIG. 8 is an assembled perspective view illustrating a delivery tube seat and a rotating housing of the atomizer according to an example embodiment; and FIG. 9 is a perspective view illustrating the rotating housing of the atomizer according to an example embodiment.

[0050] As shown in FIG. 7, the atomizer 2000 can include an upper housing 2010, a lower housing 2020, a button 2030 disposed in the upper housing portion, and a liquid reservoir (not shown in the figure) disposed in the lower housing 2020.

[0051] In addition, as shown in FIG. 8, the atomizer 2000 includes a loading assembly 1000, which can be disposed inside the atomizer 2000 for loading the liquid in the liquid reservoir into the pumping chamber of the atomizer 2000.

[0052] In some embodiments, the first component of the loading assembly 1000 can be configured as the upper housing 2010 of the atomizer 2000, and the second component of the loading assembly 1000 can be configured as the delivery tube seat 2040 of the atomizer 2000. In an example, the delivery tube seat 2040 can be configured to be rotatable with the rotation of the lower housing 2020 of the atomizer 2000. For example, the upper housing 2010 and the lower housing 2020 can be rotatable relative to each other, and the delivery tube seat 2040 can be indirectly coupled with the lower housing 2020, and by rotating the lower housing 2020 relative to the upper housing 2010, the delivery tube seat 2040 can be rotated relative to the upper housing 2010. In other words, by rotating the lower housing 2020 relative to the upper housing 2010, the second component 1020 of the loading assembly 1000 disposed in the atomizer 2000 can be rotated relative to the first component 1010, and the second component 1020 can be moved away from the first component 1010 to a pre-loading position. In this process, a portion of the liquid stored in the liquid reservoir of the atomizer 2000 can be pumped into the pumping chamber of the atomizer 2000, for example, for atomization injection.

[0053] In some embodiments, as shown in FIG. 8, the atomizer 2000 can further include a rotating housing 2050, which is sleeved on the outside of the delivery tube seat 2040, and the inner wall of the rotating housing 2050 can be provided with an axial sliding groove 2051, and the circumferential edge of the delivery tube seat 2040 is provided with a positioning guide (such as the positioning guide 1200 shown in FIG. 5) capable of sliding in the axial sliding groove 2051, and by sliding the positioning guide 1200 into the axial sliding groove 2051, the relative rotation between the delivery tube seat 2040 and the rotating housing 2050 is limited. In addition, during assembly, the axial sliding groove 2051 and the positioning guide 1200 can play a role in facilitating installation.

[0054] In the example, the rotating housing 2050 can be located inside the lower housing 2020 and arranged outside the delivery tube seat 2040. The rotating housing 2050 can transmit the rotation of the lower housing 2020 to the delivery tube seat 2040, in other words, when the rotating housing 2050 rotates, the delivery tube seat 2040 also rotates; in addition, when the delivery tube seat 2040 is released and moves towards the upper housing 2010, the rotating housing 2050 does not move upwards with the delivery tube seat 2040.

[0055] In some embodiments, the rotating housing 2050 can further include a limiting structure 2052 for limiting the axial relative position between the delivery tube seat 2040 and the rotating housing 2050.

[0056] By arranging the axial sliding groove 2051, the positioning guide 1200 and the limiting structure 2052, the delivery tube seat 2040 and the rotating housing 2050 can be relatively fixed.

[0057] In some embodiments, the limiting structure 2052 can include an elastic buckle, referring to FIG. 9, one end of the limiting structure 2052 (elastic buckle) extends radially inward from the rotating housing 2050, and the elastic buckle is configured to limit the movement of the delivery tube seat 2040 in the second axial direction opposite to the first axial direction Y after the delivery tube seat 2040 is clamped into the mounting position of the rotating housing 2050 along the first axial direction Y. Thus, while facilitating the installation of the delivery tube seat 2040, the delivery tube seat 2040 is also well limited.

[0058] In the example shown in FIG. 9, when the delivery tube seat 2040 is assembled into the rotating housing 2050 along the first axial direction Y, the delivery tube seat 2040 can move up and down above the limiting structure 2052 to complete the loading action during the spraying process. However, the limiting structure 2052 can prevent the delivery tube seat 2040 from moving downward, thereby preventing the delivery tube seat 2040 from sliding out undesirably.

[0059] It should be understood that in the present specification, the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship or dimensions based on the orientation or positional relationship or dimensions shown in the drawings, and the use of these terms is only for the convenience of description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the scope of protection of the present application.
