DETAILED DESCRIPTION

[0011] In the present disclosure, the terms “first”, “second”, and the like are used to describe various elements only and do not intend to limit the positional relationship, the time sequence relationship, or the importance relationship of the elements, and 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 description of the context, they can also refer to different instances.

[0012] The terms used in the description of various described examples in the present disclosure are only for the purpose of describing specific examples and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element can be one or more. As used herein, the term “plurality” means two or more, and the term “based on” should be interpreted as “based at least in part on”. In addition, the terms “and / or” and “at least one of” encompass any one of the listed items and all possible combinations thereof.

[0013] In the scope of the present disclosure, “atomizer” refers to a device for atomizing a liquid. Typically, an atomizer is used to atomize a fluid (e.g., a medicinal liquid or a similar fluid) and to spray the atomized fluid to the mouth or nose of a user (e.g., a patient).

[0014] In the related art, a container in an atomizer is filled with liquid to be atomized or sprayed, and in the course of movement of the container relative to a spraying assembly, the liquid in the container can be atomized and sprayed from a nozzle of the spraying assembly. However, the button assembly of the atomizer in the related art is usually rough in workmanship, and the feedback of the button to the user is unstable. Therefore, it is necessary to provide an atomizer with an improved button assembly.

[0015] Therefore, the present disclosure proposes a button assembly for an atomizer and an atomizer. In the scope of the present disclosure, the button assembly can be installed in the atomizer and can be linked with a spraying assembly of the atomizer to actuate the spraying assembly to perform a spraying action.

[0016] In the scope of the present disclosure, the "pre-loaded position" of the spraying assembly can refer to a position in which the liquid in the atomizer is loaded to be ready to be sprayed out (for example, loaded from the tank body to the pumping chamber), and in this position, the atomizer cannot autonomously perform atomization spraying without the triggering action of external force, and only the spraying assembly can be triggered by, for example, human operation (for example, pressing the button assembly according to the present disclosure) to make the spraying assembly recover from the "pre-loaded position" to the "trigger position", that is, to make the liquid in the atomizer convert from the state of being loaded to be pre-sprayed to the state of atomization spraying. In the "trigger position", the atomizer can be operated again (for example, screwed) to convert to the "pre-loaded position", so the "trigger position" can also be called the initial position.

[0017] Reference will be made below to Figures 1 to 12 The trigger assembly according to exemplary embodiments is described. Among them, Figure 1 is a schematic diagram illustrating a button assembly for an atomizer according to exemplary embodiments; Figure 2 is Figure 1 a schematic diagram of a button body of the button assembly in Figure 3 is Figure 2 a schematic diagram of another embodiment of a button body of the button assembly in Figure 4 and Figure 5 are respectively Figure 1 schematic diagrams of a first arm and a second arm in Figure 6 and Figure 7 are respectively Figure 1 schematic diagrams of the first arm and the second arm in another angle in Figure 8 and Figure 9 are respectively Figure 1 schematic diagrams of another embodiment of the first arm and the second arm in Figure 10 is a schematic diagram illustrating a button assembly for an atomizer according to exemplary embodiments in a trigger position state; Figure 11 is a schematic diagram illustrating a button assembly for an atomizer according to exemplary embodiments in an intermediate state;Figure 12 is a schematic diagram illustrating a button assembly for an atomizer in a preloaded position state according to an example embodiment.

[0018] In the context of the present disclosure, at least one arm of the button assembly has two states: "folding" and "spreading".

[0019] In addition, as Figure 1 shown, at least one arm in the present disclosure can include only the first arm 1033, or only the second arm 1034, or both the first arm 1033 and the second arm 1034. In the following description, it can be understood that the first arm 1033 and the second arm 1034 can also be replaced by embodiments including only the first arm 1033 or only the second arm 1034, which is not limited herein.

[0020] With the atomizer in different positions, the at least one arm in the present disclosure can also be converted between the corresponding states. In the case where the distal end of the at least one arm opposite to the proximal end is close to the housing of the atomizer, the button body stretches the elastic member. In the case where the distal end of the at least one arm is away from the housing of the atomizer, the button body compresses the elastic member.

[0021] For example, in the example where the at least one arm includes the first arm 1033 and the second arm 1034, in the case where the atomizer is in the trigger position (initial position), the first arm and the second arm of the button assembly can be in the spreading state, at this time, the distal ends of the first arm and the second arm are away from each other; in the case where the atomizer is in the preloaded position, the first arm and the second arm of the button assembly can be in the folding state, at this time, the distal ends of the first arm and the second arm are close to each other (compared to the case of the spreading state).

[0022] According to the button assembly of the present disclosure, by the at least one arm (for example, the first arm 1033, the second arm 1034, or both the first arm 1033 and the second arm 1034) coupled on the button body and the elastic member, the position of the button body relative to the housing of the atomizer is different when the at least one arm is in different states (due to the elastic deformation of the elastic member), and the force feedback of the user pressing the button body is different, thereby providing the user with a clear feeling and feedback for the state of the atomizer, which helps to improve the user experience and the convenience of use. Specifically, in the case where the at least one arm is spread (trigger position), the at least one arm drives the button body to move inwards through the proximal end thereof coupled on the button body, and the elastic member is in a compressed state, at this time, the feeling of pressing the button is that the resistance is large, and the stroke generated when pressing the button body is small. In the case where the at least one arm is spread (preloaded position), the at least one arm is folded and pushes the button body to move outwards through the proximal end thereof, and the spring is in a stretched state, at this time, the feeling of pressing the button is that the resistance is small, and the stroke generated when pressing the button body is large.

[0023] In addition, the linkage design between the button body and the at least one arm and the elastic member saves the internal space of the atomizer, makes the overall structure of the atomizer more compact and durable, and the elastic member is compressed and stretched during use of the atomizer, the stress is uniformly distributed, avoiding rapid aging caused by one-way stress, thereby prolonging the service life.

[0024] Firstly referring to Figures 1 to 9 , the button assembly 1030 for the atomizer comprises: a button body 1031, an elastic member 1032, and a first arm 1033 and a second arm 1034.

[0025] As shown in Figure 1 , it can be seen that the elastic member 1032 has a first end 3201 and a second end 3202 opposite to the first end 3201, wherein the first end 3201 is coupled to the button body 1031, and the second end 3202 is used to be coupled to the shell of the atomizer. Further referring to Figure 4 and Figure 5 , the first arm 1033 has a proximal end 3301 and a distal end 3302 and the second arm 1034 has a proximal end 3401 and a distal end 3402, wherein the proximal end 3301 of the first arm 1033 and the proximal end 3401 of the second arm 1034 are coupled to the button body 1031.

[0026] In the case that the distal ends of the first arm 1033 and the second arm 1034 opposite to the proximal ends are away from each other, the button body 1031 compresses the elastic member 1032, and in the case that the distal ends of the first arm 1033 and the second arm 1034 are close to each other, the button body 1031 stretches the elastic member 1032.

[0027] In some embodiments, the force acting on the button body 1031 by the first arm 1033, the second arm 1034 and the elastic member 1032 together is between 5N and 25N.

[0028] In some embodiments, the button assembly is configured to be pressed towards the housing of the atomizer under a pressing force in a range of 4N to 20N. In the present disclosure, a user actuates the button assembly by pressing the portion of the button assembly exposed outside the housing of the atomizer (e.g. the button body 1031) to trigger the atomizer to perform a spraying operation. In the case that the user presses the button body, the first arm 1033, the second arm 1034 and the elastic member 1032 coupled to the button body 1031 have an obstructive effect on the stroke of the button body, and thus the pressing force (which can also be referred to as the activation force) required to press the button assembly needs to be adapted to the force acting on the button body 1031 jointly by the first arm 1033, the second arm 1034 and the elastic member 1032. For example, in the case that the first arm 1033 and the second arm 1034 are in different states before and after dosing (spread or closed), the button body 1031 and the elastic member 1032 are also in corresponding different states, and the resistance jointly acting on the button body 1031 by the first arm 1033, the second arm 1034 and the elastic member 1032 can be in a range of 4N to 20N, and thus the activation force required to be applied on the button body 1031 needs to be in a range of 4N to 20N.

[0029] In some embodiments, at least one of the first arm 1033 and the second arm 1034 has a first fitting portion 3303 at the proximal end thereof, and the button body 1031 has a fitting hole 3101 for cooperating with the first fitting portion. For example, referring to Figure 2 and Figure 4 , the first arm 1033 has a first fitting portion 3303 at the proximal end 3301 thereof. When the first fitting portion 3303 is inserted into the fitting hole 3101 of the button body 1031, a precise mechanical fit is formed, which ensures the accurate position of the first arm 1033 during assembly and reduces the possibility of misalignment and looseness between parts.

[0030] Further referring to Figures 2 to 5 , in some embodiments, the first fitting portion 3303 has a head portion adapted to the shape of the fitting hole 3101 to install the first fitting portion 3303 into the fitting hole 3101 in a first direction D1. In some examples, for example as shown in Figure 2 , the shape of the fitting hole 3101 can be oval or other suitable shape, and the contour shape of the outermost edge of the head portion 301 of the first fitting portion 3303 is adapted to the shape of the fitting hole 3101, which can achieve that the first arm 1033 can only be assembled in a specific direction (e.g. the first direction D1 as shown in Figure 2 ). The shape of the head portion and the fitting hole further improves the assembly accuracy and stability of the button assembly.

[0031] Referring to Figure 4In some embodiments, the first assembly portion 3303 comprises a groove 302 configured to extend towards the main body portion of the first assembly portion 3033, and at least one first barb structure 303, wherein the groove 302 is configured to contract to allow the at least one first barb structure 303 to pass through the assembly hole 3101 during installation of the first assembly portion 3303 into the assembly hole, and the first barb structure 303 is configured to abut against the assembly hole 3101 when the first assembly portion 3303 is installed into the assembly hole 3101.

[0032] The design of the groove 302 allows the first assembly portion 3303 to contract when passing through the assembly hole 3101, and the barb structure smoothly passes through the aperture, thereby achieving quick and stable clamping. The design of the first barb structure 303 helps to prevent the first assembly portion 3303 from loosening / disengaging due to external force after installation, improves assembly reliability, and avoids inconsistent button assembly pressing feel or key position deviation due to loosening.

[0033] In some examples, the at least one first barb structure 303 can be symmetrically arranged on both sides of the groove 302, i.e., the number of first barb structures 303 can be two. In embodiments according to the present disclosure, the first barb structure 303 can rotate in the assembly hole 3101 of the button body 1031, and the button body 1031 and the first arm 1033 and / or the second arm 1034 can move relative to each other through rotation of the first barb structure 303. It can be understood that the first barb structure 303 in the present disclosure can also be four symmetrically arranged first barb structures.

[0034] Reference Figure 2 In some embodiments, the button body 1031 has at least one insertion portion 3102 for coupling to the housing of the atomizer, and the head of the at least one insertion portion 3102 is provided with at least one second barb structure 3103.

[0035] The at least one insertion portion 3102 is arranged such that the button assembly 1030 does not require additional tools or fasteners when the button body 1031 is installed to the housing of the atomizer, and the second barb structure 3103 provided on the head of the insertion portion 3102 is automatically locked to the inner wall of the housing, improving assembly efficiency and reducing production costs. Moreover, once the insertion is completed, in the use process, the second barb structure 3103 is tightly abutted against the inner wall of the housing, and the second barb structure 3103 can be used to limit the position of the rebound of the button body 1031, ensuring that the button assembly is firmly fixed in the housing and is not easy to loosen.

[0036] In some examples, the insertion portion 3102 can have a plate-like structure, and the second barb structure 3103 can be arranged along the end of the plate-like structure, for example as Figure 2 shown, two second barb structures 3103 can be arranged at the end of the insertion portion 3102. In addition, at least one insertion portion 3102 can be arranged symmetrically relative to the geometric center of the button body 1031, which helps to improve the stability of the installation of the button body 1031 to the housing of the atomizer.

[0037] It can be understood that, as Figure 5 and Figure 7 shown, the second arm 1034 of the button assembly 1030 can have a similar fitting portion and a head on the fitting portion, which has the same features and functions as the first fitting portion 3303 and the head 301 of the first arm 1033, and will not be described here.

[0038] With reference to Figure 2 , in some embodiments, the button body 1031 has a second fitting portion 3104, and the first end 3201 of the elastic member 1032 is sleeved on the second fitting portion 3104, and the second end 3202 of the elastic member is connected to the housing of the atomizer. The elastic member 1032 is sleeved on the second fitting portion 3104, which makes the assembly process simple and fast, and the installation of the elastic member 1032 can be completed without complex tools, reducing the manufacturing cost. In addition, the two ends of the elastic member 1032 are respectively connected to the button body and the atomizer housing, which helps to axially position the elastic member and improves the assembly stability of the assembly.

[0039] Further reference to Figure 3 , in the embodiment of the button body 1031 shown in Figure 3 , the button body 1031 is provided with a guide portion 3105. The guide portion 3105 can be matched with the corresponding guide feature of the atomizer to improve the installation accuracy of the button body 1031, and in the case of pressing the button body 1031, the guide portion 3105 helps to maintain the direction of the pressing force, avoids the instability of the button body 1031, and improves the user's experience. The number of guide portions 3105 can be two, for example as Figure 3 shown, the button body 1031 can have two guide portions 3105 which are relatively symmetrical relative to the central axis of the button body 1031. In some examples, the guide portion 3105 has an "L" shaped cross-sectional shape to improve the assembly efficiency and positioning accuracy of the guide portion 3105 and the corresponding guide feature of the atomizer.

[0040] In some examples, the elastic member 1032 can be arranged at the intermediate position of the button body 1031, which helps to uniformly stress the button body 1031 and improve the overall pressing feel of the button assembly 1030.

[0041] In some embodiments, the elastic member 1032 is a spring, the second assembly portion 3104 is shaped to fit the inner diameter of the spring 1032, and the second assembly portion 3104 is interference fitted with the spring 1032. In some embodiments, the second assembly portion 3104 is shaped to fit the inner diameter of the spring 1032, and the second assembly portion 3104 is interference fitted with the spring 1032 via the shape of the second assembly portion 3104. Figure 1 and Figure 2 In the example shown, the second assembly portion 3104 is shaped to fit the elastic member 1032, for example, the second assembly portion 3104 can be a “cross” shape, the “cross” profile fits the inner diameter of the elastic member and the second assembly portion 3104 can be interference fitted with the elastic member via the “cross” profile of the second assembly portion 3104 or any other suitable shape.

[0042] The shape of the second assembly portion 3104 fitting the inner diameter of the elastic member helps to position the elastic member radially, avoids the elastic member coupled to the button body from changing position or shifting during pressing, and further improves the assembly stability of the component.

[0043] In some embodiments, the pressing force is related to the elastic force of the elastic member 1032 acting on the button body 1031. For example, the elastic force of the elastic member 1032 acting on the button body 1031 is between 2N and 8N.

[0044] In some examples, the atomizer further comprises: a first component 1010 and a second component 1020, wherein the first component 1010 and the second component 1020 are configured such that, in the case that the second component 1020 rotates relative to the first component 1010 towards a second direction, the second component 1020 can move away from the first component 1010 to a preloaded position, and wherein the first arm and the second arm are partially disposed around the first component 1010 and / or the second component 1020, and in the case that the second component 1020 moves to the preloaded position, the first arm 1033 and the second arm 1034 slide relative to the outer peripheral surface of the second component 1020, so that the respective distal ends 3302, 3402 of the first arm 1033 and the second arm 1034 move close to each other.

[0045] It can be seen that, Figure 10 the second component 1020 in the trigger position (also the initial position), in this case, the first arm and the second arm of the button assembly 1030 are in an open state, and the button body squeezes the elastic member. Figure 12 the second component 1020 in the preloaded position, in this case, the first arm 1033 and the second arm 1034 of the button assembly 1030 are in a closed state, and the button body stretches the elastic member. And Figure 11The second component 1020 is in an intermediate state between the trigger position and the preload position. When the second component 1020 rotates relative to the first component 1010 in a second direction, at least one arm of the button assembly 1030 (e.g., the first arm 1033 and / or the second arm 1034) always surrounds the first component 1010 and / or the second component 1020, thus preventing unintended disengagement between the first component 1010 and / or the second component 1020 and the at least one arm, thereby preventing accidental spraying from the atomizer. In some examples, the second component 1020 is configured as a delivery tube holder (also called a tube support) of the atomizer, and at least one arm of the button assembly 1030 can always hold the tube support to prevent unintended accidental spraying during rotation.

[0046] In the example, in the preload position, the liquid medicine can be pumped from the storage tank into the pumping chamber located at the first component 1010 or the second component 1020; in the trigger position, the liquid medicine can be sprayed outward from the pumping chamber through the nozzle. Accordingly, after the spraying is completed, the second component 1020 in the trigger position is in the initial position of the next action cycle, so that it can move back to the preload position.

[0047] According to the button assembly 1030 disclosed herein, the button body (due to the elastic deformation of the elastic element) is positioned differently relative to the atomizer housing before and after the atomizer pumps the liquid medicine into the pumping chamber, i.e., when the first arm 1033 and the second arm 1034 are in different states. The force feedback of the user pressing the button body is also different, thereby providing the user with a clear sense and feedback on the atomizer status, which helps to improve the user experience and ease of use.

[0048] The first component 1010 and the second component 1020 are configured such that when the second component 1020 rotates relative to the first component 1010 in a second direction D2, it can move away from the first component 1010 to a preloaded position. For example, refer to Figures 10 to 12 ,from Figure 10 Starting from the position shown, the second component 1020 is oriented relative to the first component 1010. Figure 10 The second component 1020 rotates clockwise, and as shown in 10, as the second component 1020 rotates, the second component 1020 gradually moves away from the first component 1010; when the second component 1020 rotates further clockwise, the second component 1020 moves to... Figure 12 The preload position is shown. In the example, the rotational motion between the first component 1010 and the second component 1020 can also be converted into relative movement between them via a rack and pinion mechanism or a screw mechanism.

[0049] like Figures 10 to 12As shown, as an alternative, the first arm, the second arm, and the elastic element can also be connected via button connector 1035 (for the sake of view simplicity, only shown here). Figure 12 (As indicated by the indicator) is coupled to the button body. For example, the first arm, the second arm, and the elastic element are first connected to the button connector 1035, and the button connector 1035 is then connected to the button body. It should be understood that... Figures 10 to 12 The button component 1030 in the middle can also be used. Figure 1 The button component shown is used instead, and its features and functions are similar to those of the button component described in this disclosure, and will not be repeated here.

[0050] In some examples, the first arm 1033 and the second arm 1034 of the button assembly 1030 may be partially disposed around the first component 1010 and / or the second component 1020. For example, the first arm 1033 and the second arm 1034 of the button assembly 1030 may be connected to the first component 1010 and partially disposed around the outer periphery of the first component 1010; or the first arm 1033 and the second arm 1034 of the button assembly 1030 may be connected to the second component 1020 and partially disposed around the outer periphery of the second component 1020; or the first arm 1033 and the second arm 1034 of the button assembly 1030 may be connected to both the first component 1010 and the second component 1020 and partially disposed around both.

[0051] In some embodiments, such as Figures 4 to 7 As shown, at least one of the first arm 1033 and the second arm 1034 includes a connecting portion 3305. The connecting portion 3305 is pivotally connected to the first component 1010 and / or the second component 1020 such that when the button body 1031 is pressed, the corresponding first arm 1033 and / or the second arm 1034 pivots about the connecting portion.

[0052] For example, such as Figures 10 to 11 As shown, the connecting portion 3305 is pivotally connected to a shaft on the first component 1010. Thus, when a user presses the button assembly 1030 (e.g., the button body or button connector), the proximal end 3301 of the first arm 1033 moves radially inward (towards the first component 1010), causing the bent first arm to rotate about its own connecting portion 3305. Consequently, the distal end 3302 of the first arm 1033 moves radially outward (away from the first component 1010). It is understood that the second arm 1034 may also have a corresponding connecting portion, with features and function similar to the connecting portion 3305 of the first arm, and will not be described further here. In other words, when the user presses the button, the distal ends of the first arm 1033 and the second arm 1034 will move away from each other.

[0053] In some embodiments, the distal end of the first arm 1033 and / or the second arm 1034 comprises a bearing portion extending radially inwardly from the body thereof, the bearing portion being configured to abut the second component 1020 in the event that the first arm 1033 and / or the second arm 1034 slides relative to the peripheral surface of the second component 1020.

[0054] For example, the body of the first arm 1033 and / or the second arm 1034 can be generally annular in shape, such that the inner periphery thereof is able to substantially surround the first component 1010 or the second component 1020 having a generally cylindrical outer surface. The bearing portion 3306 of the first arm 1033 and / or the second arm 1034 extends radially from the annular body to the annular interior. As Figure 8 As shown, the distal end 3302 of the first arm 1033 has a bearing portion 3306, it will be appreciated that the second arm 1034 can also have a corresponding bearing portion 3306, which is not described again here.

[0055] As can be seen from Figures 10 to 12 During rotation of the second component 1020 relative to the first component 1010, the first arm 1033 and / or the second arm 1034 will not interfere with the rotation of the second component 1020, as the first arm 1033 and / or the second arm 1034 will be wrapped around the periphery of the first component 1010 and / or the second component 1020. Instead, as the second component 1020 rotates, the first arm 1033 and / or the second arm 1034 will slide relative to the peripheral surface of the second component 1020. When the second component 1020 moves to the pre-loaded position as shown in Figure 12 The radially inwardly extending bearing portion 3306 of the first arm 1033 and / or the second arm 1034 is able to abut the second component 1020 when the second component 1020 is in the pre-loaded position, as the bearing portion 3306 is closer to the inner side in the radial direction relative to the body, thereby preventing the second component 1020 from moving away from the pre-loaded position.

[0056] For example, Figure 12 The upper surface of the bearing portion 3306 abuts 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.

[0057] In some embodiments, the first arm 1033 and / or the second arm 1034 can be configured such that the second component 1020 can abut against the bearing portion 3306 of the first arm 1033 and / or the second arm 1034 exactly when the second component 1020 is disengaged from the first component 1010. For example, the first arm 1033 and / or the second arm 1034 can be configured in this way by setting the size of the body of the first arm 1033 and / or the second arm 1034 (or in other words, the position of the bearing portion 3306 of the first arm 1033 and / or the second arm 1034). In an example, the first arm 1033 and / or the second arm 1034 can be connected to the first component 1010, and the position of the bearing portion 3306 of the first arm 1033 and / or the second arm 1034 can be set at the position where the second component 1020 is exactly disengaged from the first component 1010. In this way, when the second component 1020 is disengaged from the first component 1010, the second component 1020 is smoothly abutted by the bearing portion 3306, so that the second component 1020 can be smoothly transitioned from the intermediate state to the preloaded state, without causing the liquid to be ejected in small amounts due to non-smooth transition.

[0058] In some embodiments, in the case where the second component 1020 is moved to the preloaded position, the bearing portion 3306 is configured to disengage from the second component 1020 to release the second component in the case where the button body 1031 is pressed. For example, the first arm 1033 and / or the second arm 1034 can be configured in this way by setting the size of the bearing portion 3306 of the first arm 1033 and / or the second arm 1034. In an example, continuing to refer to Figures 1 to 6 , the bearing portion 3306 can not necessarily extend inwardly too much, as long as the abutment requirement for the second component 1020 can be met, so that when it is required to move the second component 1020 from the preloaded position to the triggered position, it is only required to slightly move the position of the bearing portion 3306 (for example, slightly move the bearing portion 104 outwardly in the radial direction in Figure 6 , to release the second component 1020.

[0059] In some embodiments, the button assembly further comprises another elastic member 1036. The other elastic member 1036 is configured to store energy when the second component 1020 is moved away from the first component 1010, and wherein in the case where the bearing portion 3306 is disengaged from the second component 1020, the second component 1020 is moved towards the first component 1010 to the triggered position under the action of the other elastic member 1036.

[0060] The other elastic member 1036 is configured to store energy when the second component 1020 moves away from the first component 1010. For example, the other elastic member 1036 can be a spring or other elastic member, as long as it is capable of storing energy through elastic deformation. In an example, the other elastic member 1036 (e.g. a spring) can be arranged on the side of the second component 1020 close to the first component 1010, and stretch when the second component 1020 moves away from the first component 1010 to store energy, and push the second component 1020 to the trigger position by pulling force when the other elastic member 1036 rebounds. The other elastic member 1036 (e.g. a spring) can be arranged on the side of the second component 1020 away from the first component 1010, and compress when the second component 1020 moves away from the first component 1010 to store energy, and push the second component 1020 to the trigger position by pushing force when the other elastic member 1036 rebounds.

[0061] Referring back to Figures 6 to 9 , the distal end 3302 and the distal end 3402 can include a limiting protrusion 3307 arranged adjacent to the bearing portion 3306 and protruding from the bearing surface of the bearing portion 3306, the limiting protrusion 3307 being configured to block the rotation of the second component 1020 towards the second direction D2 when the bearing portion 3306 abuts against the second component 1020.

[0062] In some examples, when the second component 1020 is in the preloaded position, the bearing portion 3306 abuts against the second component 1020, and the limiting protrusion 3307 blocks the rotation of the second component 1020 towards the second direction D2, thereby preventing the undesired rotation between the second component 1020 and the first component 1010 towards the second direction D2. In some embodiments, the end of the second component 1020 is provided with a limiting step, and the limiting protrusion 3307 blocks the rotation of the second component 1020 towards the second direction D2 by abutting against the limiting step.

[0063] In some embodiments, when the bearing portion 3306 abuts against the second component 1020, the limiting protrusion contacts the second component 1020 in a tangential manner to block the rotation of the second component 1020 towards the second direction D2. The tangential contact can be achieved by one of the limiting protrusion and the second component 1020 having an arc shape. For example, in the case where the limiting protrusion is provided with an arc shape, the second component 1020 can be provided with a flat surface, and the limiting protrusion contacts the flat surface of the second component 1020 in a tangential manner to block the rotation of the second component 1020 towards the second direction D2. Figure 8 and Figure 9In the illustrated embodiment, the surface of the limiting protrusion 3307* for blocking the rotation of the second component 1020 towards the second direction D2 has an arc shape. In some examples, it can also be that the surface of the second component 1020 in contact with the limiting protrusion has an arc shape, while the corresponding surface of the limiting protrusion can be, for example, a flat surface. In the case where the atomizer is in the preloaded position, when the user presses the button assembly 1030, the button body will be impeded by the friction between the first arm 1033 and / or the second arm 1034 and the second component 1020 (for example, the friction at the arc surface of the limiting protrusion 3307*), and thus the size of the friction can affect the activation force required to be applied on the button body 1031. By tangential contact of the limiting protrusion with the second component 1020 (for example, by setting the surface of the limiting protrusion 3307* for blocking the rotation of the second component 1020 towards the second direction D2 to have an arc shape), the size of the above-mentioned friction can be controlled within a desired range, thereby improving the feel when the user presses. For example, compared to the case where the surface is flat, the arc-shaped surface can appropriately reduce the above-mentioned friction, thereby making the pressing operation smoother.

[0064] In some embodiments, the pressing force is related to the friction between each of the at least one arm and the second component. In some examples, the size of the friction between the first arm 1033 or the second arm 1034 and the second component 1020 is between 1 N and 6 N.

[0065] A second aspect of the present disclosure provides an atomizer. The following describes the atomizer of the present disclosure in conjunction with Figures 13 to 15 The atomizer of the present disclosure is described. Among them, Figure 13 is a perspective view illustrating an atomizer according to an exemplary embodiment; Figure 14 is a side view illustrating an atomizer according to an exemplary embodiment; Figure 15 is a perspective view illustrating Figure 14 is a cross-sectional view of the atomizer in the A-A section.

[0066] The atomizer 2000 includes a spray assembly and a button assembly 1030 according to the present disclosure for pressing to actuate the spray assembly to spray liquid. The spray assembly 2060 can be mounted in the atomizer 2000 and can be linked with the button assembly 1030 of the atomizer, and the spray assembly is used to deliver the atomized liquid to be sprayed to the corresponding chamber.

[0067] As Figure 13 and Figure 14 illustrated, the atomizer 2000 can include an upper housing 2010, a lower housing 2020, and a button 2030 disposed in the upper housing portion. In addition, as Figure 15As shown, the atomizer 2000 can further include a delivery tube base 2040 and a rotating housing 2050 disposed in the lower housing 2020.

[0068] In some embodiments, the first component 1010 can be configured as the upper housing 2010 of the atomizer 2000, the second component 1020 is configured as the delivery tube base 2040 of the atomizer 2000, and the delivery tube base 2040 is configured to be rotatable with the rotation of the lower housing 2020 of the atomizer 2000.

[0069] For example, the upper housing 2010 and the lower housing 2020 can be rotatable relative to each other, and the delivery tube base 2040 is coupled with the lower housing 2020, by rotating the lower housing 2020 relative to the upper housing 2010, the delivery tube base 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 trigger assembly 1000 disposed in the atomizer 2000 can be rotated relative to the first component 1010, and the second component 1020 is 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, ready for atomization ejection.

[0070] In some embodiments, the atomizer 2000 includes a rotating housing 2050 for accommodating at least a portion of the spray assembly 2060, and the distal end of at least one of the first arm 1033 and the second arm 1034 has a mating portion that mates with the rotating housing. In some examples, the mating portion can be a protrusion (as shown in Figure 6 and Figure 7 the mating portion 3308) or a plurality of elongated prisms (as shown in Figure 8 and Figure 9 the mating portion 3308*).

[0071] In some examples, the rotating housing 2050 is located inside the lower housing 2020 and disposed outside the delivery tube base 2040. The rotating housing 2050 can transmit the rotation of the lower housing 2020 to the delivery tube base 2040, in other words, when the rotating housing 2050 rotates, the delivery tube base 2040 also rotates; in addition, when the delivery tube base 2040 is released and moves towards the upper housing 2010, the rotating housing 2050 does not move upwards with the delivery tube base 2040.
