[0039] In the present disclosure, the use of the terms "first", "second", etc. to describe various elements is not intended to convey temporal relationships, chronological order, or priority of importance, unless specified otherwise. Such terms are merely used to distinguish one element from another. In some examples, a first element and a 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.

[0040] The terminology used in the description of the various described examples in the present disclosure is only for the purpose of describing particular ones of the examples and is not intended to be limiting. Unless specifically defined herein, any terms used herein that are not specifically defined are intended to be given their ordinary meaning to a person skilled in the art. As used herein, the term "plurality" means two or more, and the term "based on" shall be construed 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.

[0041] In the context of the present disclosure, an "atomizer" refers to a device for atomizing a liquid. Generally, an atomizer is used to atomize a fluid (e.g., a medicinal liquid or the like) and to spray the atomized fluid to the mouth or nose of a user (e.g., a patient).

[0042] In the related art, a liquid can be sprayed by triggering an atomizer. For example, an atomizer can be triggered by a mechanical means (e.g., a press or a rotation switch). However, the triggering of an atomizer is often not stable enough, resulting in a process of atomization and spraying of a liquid that is not always smooth.

[0043] In view of this, the present disclosure proposes a trigger assembly for an atomizer and an atomizer. In the context of the present disclosure, a "trigger assembly" refers to an assembly for controlling the triggering of an atomizer, for example, an assembly capable of controlling and / or preventing an atomizer from performing an atomization or spraying operation. The trigger assembly can be installed in an atomizer and can be linked with a press switch and / or a rotation switch of the atomizer. Here, the reliable conversion of the trigger assembly between a preloaded position and a triggered position is achieved by the actuator hindering the second component from leaving the preloaded position in the case that the second component moves to the preloaded position, and releasing the second component to move toward the first component to the triggered position in the case that the actuator is triggered.

[0044] In the context of the present disclosure, the "preloaded position" of the trigger assembly can refer to a position in which a liquid in the atomizer is loaded to be ready to be sprayed out (e.g., loaded from a tank to a pumping chamber), in which position the atomizer cannot autonomously perform atomization spraying without the triggering action of an external force, and only when the trigger assembly is triggered by, for example, a human operation (e.g., a press) can the trigger assembly recover from the "preloaded position" to the "triggered position", that is, the state of the liquid in the atomizer is converted from the pre-spraying state to the atomization spraying state. In the "triggered position", the atomizer can be operated again (e.g., twisted) to convert to the "preloaded position", so the "triggered position" can also be referred to as an initial position.

[0045] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present disclosure, and therefore only serve as examples, and cannot limit the protection scope of the present disclosure.

[0046] FIG. 1 is a schematic diagram illustrating a trigger assembly for an atomizer in a triggered position state according to an exemplary embodiment. Referring to FIG. 1, the trigger assembly 1000 includes a first component 1010, a second component 1020, and an actuator 1040.

[0047] The first component 1010 and the second component 1020 are configured such that the second component 1020 can move away from the first component 1010 to a pre-loaded position in the case that the second component 1020 rotates relative to the first component 1010 towards the first direction D1. For example, with reference to FIGS. 1 to 4, starting from the position shown in FIG. 1, the second component 1020 rotates relative to the first component 1010 towards the clockwise direction in FIG. 1, and as the second component 1020 rotates, the second component 1020 gradually moves away from the first component 1010 as shown in FIGS. 2 and 3; when the second component 1020 rotates further towards the clockwise direction, the second component 1020 moves to the pre-loaded position shown in FIG. 4. In the example, the rotational movement between the first component 1010 and the second component 1020 can be converted into relative movement between the two by a rack and pinion mechanism or a screw mechanism.

[0048] The first component 1010 further comprises a rib plate 1012. The rib plate 1012 can be a plate-like structure (plate-like structure may, for example, refer to a structure with a thickness that is relatively small compared to its width and length) extending along the second direction D2 from the outer surface of the first component 1010 in the second direction D2, and thus can strengthen the structure of the first component 1010. At the same time, the first actuator 1040 can abut against the rib plate 1012, and thus the rib plate 1012 can also provide support or limit for the first actuator 1040 in the axial direction D3, so that the movement of the first actuator 1040 relative to the first component 1010 is relatively stable, and to some extent, unnecessary shaking or displacement of the first actuator 1040 in the axial direction D3 when moving can be avoided.

[0049] It can be understood that the specific form of the rib plate 1012 can be a flat plate or a curved plate, and the present disclosure does not limit the specific form of the rib plate 1012.

[0050] The first actuator 1040 is configured to hinder the second component 1020 from leaving the pre-loaded position in the case that the second component 1020 moves to the pre-loaded position, and is configured to release the second component 1020 when triggered, so that the second component 1020 moves towards the first component 1010 to the triggered position under the action of the elastic member 1030. For example, the first actuator 1040 can have a surface for blocking the second component 1020, and the position of the actuator 1040 relative to the second component 1020 can change when triggered, thereby releasing the second component 1020. In this way, reliable conversion of the trigger assembly 1000 between the pre-loaded position and the triggered position is achieved.

[0051] As can be seen from FIGS. 1-4, during the rotation of the second component 1020 relative to the first component 1010, the first actuator 1040 does not interfere with the rotation of the second component 1020 because the first actuator 1040 is disposed around the periphery of the first component 1010. Instead, as the second component 1020 rotates, the first actuator 1040 moves relative to the outer circumferential surface of the second component 1020. When the second component 1020 moves to the pre-loaded position as shown in FIG. 4, the first actuator 1040 can abut the second component 1020, thereby hindering the second component 1020 from moving away from the pre-loaded position.

[0052] For example, the upper surface of the carrier portion 1042 in FIG. 4 can abut the lower surface of a portion of the second component 1020, thereby preventing the second component 1020 from moving further downwardly away from the pre-loaded position. For another example, the body 1041 of the first actuator 1040 can have a substantially annular shape, such that the inner periphery thereof can substantially surround the first component 1010 or the second component 1020 having a substantially cylindrical outer surface. While the carrier portion 1042 of the first actuator 1040 extends radially from the annular body 1041 toward the annular interior.

[0053] For example, the first actuator 1040 can be configured such that when the second component 1020 is disengaged from the first component 1010, the second component 1020 can abut the carrier portion 1042 of the first actuator 1040. For example, the first actuator 1040 can be configured as described above by sizing the body 1041 of the first actuator 1040 (or the position of the carrier portion 1042 of the first actuator 1040). In an example, the first actuator 1040 can be coupled to the first component 1010, and the position of the carrier portion 1042 of the first actuator 1040 can be set at a position where the second component 1020 is disengaged from the first component 1010. Thus, when the second component 1020 is disengaged from the first component 1010, the second component 1020 is smoothly abutted by the carrier portion 1042, thereby enabling a smooth transition of the second component 1020 from the intermediate state to the pre-loaded state without causing a small amount of liquid to be ejected due to a non-smooth transition.

[0054] For example, the bearing portion 1042 can be configured to disengage the second component 1020 to release the second component 1020 when the first actuator 1040 is triggered. For example, the first actuator 1040 can be configured as described above by setting the size of the bearing portion 1042 of the first actuator 1040. In examples, with continued reference to FIGS. 1-4, the bearing portion 1042 can not necessarily extend inwardly too much, as long as the abutting requirement for the second component 1020 can be met, so that when it is necessary to convert the second component 1020 from the preloaded position to the triggered position, only a slight movement of the position of the bearing portion 1042 (for example, slightly moving the bearing portion 104 outwardly in the radial direction in FIG. 5) is needed to release the second component 1020.

[0055] Thus, by providing the rib plate 1012 at the first component 1010 and abutting the first actuator 1040 against the rib plate 1012, the structural stability of the first component 1010 and the entire trigger assembly 1000 is improved to some extent, and at the same time, the movement of the first actuator 1040 relative to the first component 1010 can be relatively smooth, unnecessary shaking or displacement of the first actuator 1040 in the axial direction D3 when moving can be avoided to some extent, stable conversion of the trigger assembly 1000 between the preloaded position and the triggered position is achieved to some extent, and the trigger stability is improved.

[0056] In some embodiments, the first actuator 1040 further includes an actuator guide, and the actuator guide can move relative to the rib plate 1012 in a manner cooperating with the rib plate 1012. When the trigger assembly 1000 is converted between the preloaded position and the triggered position, the rib plate 1012 is connected at the first component 1010 and is fixed in position, while the first actuator 1040 moves relative to the trigger assembly. During the movement of the first actuator 1040 as described above, the actuator guide of the first actuator 1040 always cooperates with the rib plate 1012, so that the rib plate 1012 can guide the movement of the first actuator 1040 and control the movement trajectory of the first actuator 1040 to some extent, thereby achieving stable conversion of the trigger assembly 1000 between the preloaded position and the triggered position to some extent, and improving the trigger stability.

[0057] In some embodiments, as shown in FIG. 4, the trigger assembly 1000 further includes a button connecting piece 1060, the button connecting piece 1060 is connected with the first actuator 1040, and the first actuator 1040 is moved relative to the first component 1010 by operating the button connecting piece 1060. For example, the button connecting piece 1060 can be connected with the button of the atomizer, for example, the user can press the button and thereby press the button connecting piece 1060, thereby achieving operation of the first actuator 1040.

[0058] In some embodiments, as shown in FIG. 2, the rib plate 1012 includes a first rib plate 1013 and a second rib plate 1014, a first sliding slot 1051 is defined between the first rib plate 1013 and the second rib plate 1014, and the actuator guide includes a first slider 1041 configured to slide within the first sliding slot 1051 to provide guidance for the movement of the first actuator 1040 relative to the first component 1010. For example, as the first slider 1041 slides within the first sliding slot 1051, the first actuator 1040 can achieve a stable transition between the preloaded position and the triggered position, thereby improving the trigger stability.

[0059] Thus, by providing two rib plates (the first rib plate 1013 and the second rib plate 1014), the structural support of the rib plate to the first actuator 1040 can be further improved, and the movement trajectory of the first actuator 1040 can be further accurately controlled by the first slider 1041 sliding within the first sliding slot 1051 formed between the two rib plates, so that the first actuator 1040 can achieve a stable transition between the preloaded position and the triggered position, thereby improving the trigger stability.

[0060] In some embodiments, as shown in FIG. 2, the first rib plate 1013 and the second rib plate 1014 extend substantially along the second direction D2, which is a radial direction away from the first component 1010. Since the first rib plate 1013 and the second rib plate 1014 extend substantially along the second direction D2, the direction of the first sliding slot 1051 defined thereby is also substantially along the second direction D2, which improves the stroke range of the first actuator 1040 in the second direction D2, avoiding hindering the stable transition of the first actuator 1040 between the preloaded position and the triggered position due to the too short stroke range.

[0061] In some embodiments, the width of the first sliding slot 1051 at different positions along the second direction D2 is substantially equal. As shown in FIG. 8, the width of the first sliding slot 1051 at different positions along the second direction D2 can be substantially matched with the first slider 1041. Thus, the accuracy of the control of the movement trajectory of the first actuator 1040 can be improved, so that the first actuator 1040 can achieve a stable transition between the preloaded position and the triggered position, thereby improving the trigger stability.

[0062] In some embodiments, the movement of the first actuator 1040 relative to the first component 1010 comprises a translation towards or away from the first component 1010. A translation refers to a movement in which any two points on a moving body are connected by a straight line that remains parallel throughout the movement, and there is no relative rotation between the points on the moving body. In the case of a translation of the first actuator 1040 towards or away from the first component 1010, the first actuator 1040 requires less space for movement, which facilitates the arrangement of the internal structure of the trigger assembly 1000.

[0063] In some embodiments, as shown in FIGS. 5, 6 and 7, the first actuator 1040 is configured in the shape of a curved lever, which is at least partially disposed around the first component 1010 and / or the second component 1020, and wherein the curved lever comprises a first end portion 1043 for obstructing the second component 1020 from leaving the preloaded position, and a second end portion 1044 connected with the button connector 1060, and the first end portion 1043 is moved relative to the first component 1010 by operating the button connector 1060. In this way, when a user presses the button, and thus the button connector 1060, the second end portion 1044 of the first actuator 1040 moves radially inward (towards the first component 1010), so that the curved lever-shaped first actuator 1040 rotates around its connection site 1045, and thus the first end portion 1043 moves radially outward (away from the first component 1010).

[0064] In some embodiments, as shown in FIGS. 5, 6 and 7, the first actuator 1040 further comprises a connection site 1045 between the first end portion 1043 and the second end portion 1044, and wherein the first actuator 1040 is configured to be able to pivot around the connection site 1045, so that the first end portion 1043 is able to move relative to the first component 1010.

[0065] In some embodiments, the connection site 1045 comprises a rotating shaft, a pivoting hole or any other mechanical structure that enables the first actuator 1040 to pivot around the connection site 1045.

[0066] In some embodiments, the ratio of the distance between the first end 1043 and the connection site 1045 to the distance between the first end 1043 and the second end 1044 is in the range of 0.3 to 0.7. As shown in FIG. 8, since the first end 1043 and the second end 1044 are distributed at two ends of the connection site 1045 (the pivot axis), the ratio of the distance between the first end 1043 and the connection site 1045 to the distance between the first end 1043 and the second end 1044 is limited to about 0.5, so that the difference between the movement stroke ranges of the first end 1043 and the second end 1044 is not too large, which is beneficial to the control of the movement trajectory of the first end 1043, and thus improves the trigger stability.

[0067] It should be noted that since the first actuator 1040 can have a partial curve structure (for example, a circular arc or an elliptical arc), the distance between the first end 1043 and the connection site 1045 can be the straight-line distance between the first end 1043 and the connection site 1045. Similarly, the distance between the first end 1043 and the second end 1044 can be the straight-line distance between the first end 1043 and the second end 1044.

[0068] In some embodiments, the ratio of the distance between the first end 1043 and the connection site 1045 to the distance between the first end 1043 and the second end 1044 is in the range of 0.4 to 0.6. In other embodiments, the ratio of the distance between the first end 1043 and the connection site 1045 to the distance between the first end 1043 and the second end 1044 is 0.5.

[0069] In some embodiments, as shown in FIG. 3 and FIG. 7, the trigger assembly 1000 further comprises a second actuator 1070 configured to impede the second component 1020 from moving away from the pre-loaded position in the case that the second component 1020 is in the pre-loaded position; and configured to release the second component 1020 in the case that the trigger assembly 1000 is triggered, to move the second component 1020 towards the first component 1010 to the triggered position, the second actuator 1070 comprises a second slider 1071, and wherein the rib plate 1012 further comprises a third rib plate 1015 and a fourth rib plate 1016, the second slot 1052 is defined between the third rib plate 1015 and the fourth rib plate 1016. Similar to the first slider 1041, as shown in FIG. 9, the second slider 1071 is configured to slide within the second slot 1052, thereby providing a guide for the movement of the second actuator 1070 relative to the first component 1010. In the radial direction, the first actuator 1040 and the second actuator 1070 can be located on substantially opposite sides of the first component 1010. In this way, the first actuator 1040 and the second actuator 1070 simultaneously control the position of the second component 1020 in two directions, further enabling reliable conversion of the trigger assembly 1000 between the pre-loaded position and the triggered position, thereby improving trigger stability.

[0070] In some embodiments, the third rib plate 1015 and the fourth rib plate 1016 are both symmetrically arranged with the first rib plate 1013 and the second rib plate 1014. For example, as shown in FIG. 9, the first rib plate 1013 and the second rib plate 1014 are both located on the left side of the first component 1010, and the third rib plate 1015 and the fourth rib plate 1016 are located on the right side of the first component 1010. Since the cross-section of the first component 1010 can be substantially cylindrical in structure, the aforementioned left side and right side can be the two ends of the diameter of the cylindrical first component 1010, thereby being able to more effectively limit the movement range of the first actuator 1040 and the second actuator 1070 to substantially opposite sides of the first component 1010. In this way, the first actuator 1040 and the second actuator 1070 simultaneously control the position of the second component 1020 in two directions, further enabling reliable conversion of the trigger assembly 1000 between the pre-loaded position and the triggered position, thereby improving trigger stability.

[0071] In some embodiments, the actuator guide comprises a groove (not shown in the figures) formed on a surface of the first actuator 1040 facing the rib plate 1012, and wherein at least a portion of the rib plate 1012 is located within the groove when the first actuator 1040 moves relative to the rib plate 1012, and the first actuator 1040 is movable along the rib plate 1012, thereby providing a guide for the movement of the first actuator 1040 relative to the first component 1010. In this way, the guide for the first actuator 1040 can be achieved by the rib plate 1012 without the need for additional components, which can reduce the number of components of the trigger assembly 1000 while achieving reliable switching of the trigger assembly 1000 between the pre-loaded position and the triggered position to improve trigger stability.

[0072] In some embodiments, as shown in FIGS. 10 and 12, the elastic member 1030 is configured to store energy when the second component 1020 moves away from the first component 1010. For example, the elastic member 1030 can be a spring or other type of elastic member as long as it is capable of storing energy through elastic deformation. In an example, the elastic member 1030 (e.g., a spring) can be disposed on a 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 push the second component 1020 to the triggered position through the pulling force when the elastic member 1030 rebounds; in the example shown in FIG. 10, the elastic member 1030 (e.g., a spring) can be disposed on a 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 push the second component 1020 to the triggered position through the pushing force when the elastic member 1030 rebounds.

[0073] Two aspects of the present disclosure provide an atomizer 2000. The atomizer 2000 comprises the trigger assembly 1000 of the present disclosure, which is used to trigger the atomizer 2000 to spray an atomized fluid.

[0076] In some embodiments, as shown in FIGS. 10-12, the first component 1010 can be configured as an upper housing 2010 of an atomizer 2000, and by rotating the lower housing 2020 relative to the upper housing 2010, the second component 1020 of the trigger 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 preloaded position. During this process, a portion of the liquid stored in the tank of the atomizer 2000 can be pumped into the pumping chamber of the atomizer 2000, for example, in preparation for atomization injection.

[0077] In some embodiments, as shown in FIG. 9, both ends of the first rib plate 1013, the second rib plate 1014, the third rib plate 1015, and the fourth rib plate 1016 can be connected to the first component 1010 and the housing 2010 in the radial direction, respectively, thereby improving the structural strength of the atomizer 2000 as a whole, and also facilitating more accurate control of the accuracy of the motion trajectory of the first actuator 1040 and / or the second actuator 1070, thereby improving trigger stability.
