Description

Technical Field

[0001] This disclosure relates to the field of atomization technology, and more particularly to a triggering component and an atomizer for an atomizer. Background Technology

[0002] Atomizers can atomize liquids (such as medications) into droplets. In related technologies, the container in the atomizer contains the liquid to be atomized or sprayed. During the stroke of the container relative to the spray assembly, the liquid in the container can be atomized and sprayed from the nozzle of the spray assembly. However, the triggering of such atomizers is often not stable enough, resulting in the atomization and spraying process of the liquid often not being smooth.

[0003] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section.

[0038] In this disclosure, unless otherwise stated, the use of terms such as "first," "second," etc., to describe various elements is not intended to limit the positional, temporal, or importance relationships of these elements; such terms are merely used to distinguish one element from another. In some examples, the first element and the second element may refer to the same instance of that element, while in other cases, based on the context, they may refer to different instances.

[0039] The terminology used in the description of the various examples described in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context explicitly indicates otherwise, an element may be one or more unless the number of elements is specifically limited. As used herein, the term "multiple" means two or more, and the term "based on" should be interpreted as "at least partially based on". Furthermore, the terms "and / or" and "at least one of..." cover any one of the listed items and all possible combinations thereof.

[0040] Within the scope of this disclosure, "nebulizer" refers to a device for atomizing liquids. Typically, nebulizers are used to atomize fluids (such as medications or similar fluids) and spray the atomized fluid into the mouth or nose of a user (such as a patient).

[0041] In related technologies, liquid can be sprayed by triggering the atomizer. For example, the atomizer can be triggered mechanically (e.g., by pressing or rotating a switch). However, the operation of some atomizers remains inconvenient, especially when multiple operations are required for the user to complete the atomization, which can easily lead to misoperation. For example, when the atomizer is set to require a rotational operation to complete the spray, the user may perform an unintended reverse rotation or over-rotation. These misoperations may cause interference between components in the atomizer or result in inaccurate atomized dosage.

[0042] In view of this, this disclosure provides a triggering component and an atomizer for an atomizer. Within the scope of this disclosure, a "triggering component" refers to a component for controlling the triggering of an atomizer, such as a component capable of controlling and / or preventing the atomizer from performing atomization or spraying operations. The triggering component can be installed in the atomizer and can be linked to the atomizer's push-button switch and / or rotary switch. Here, by providing a retractable anti-reverse stop, it is possible to prevent the second component from rotating in an undesirable reverse direction when it has moved to the preloaded position.

[0043] The following will refer to Figures 1 to 8 The triggering component according to an exemplary embodiment will be described. Wherein, Figure 1 This is a schematic diagram illustrating the triggering component for an atomizer in a triggering position state according to an exemplary embodiment; Figure 2 and Figure 3 This is a schematic diagram illustrating the triggering component for an atomizer in an intermediate state according to an exemplary embodiment; Figure 4 and Figure 5 This is a schematic diagram illustrating the trigger assembly for an atomizer in a preloaded position state according to an exemplary embodiment. Furthermore, Figure 6 This is a schematic diagram illustrating the actuator and button connector of the trigger assembly for an atomizer according to an exemplary embodiment; and Figure 7 This is a schematic diagram illustrating the actuator and button connector of a trigger assembly for an atomizer, according to an exemplary embodiment, mounted on a first component; Figure 8 This is a schematic diagram illustrating an anti-reverse stop for a trigger assembly of an atomizer according to an exemplary embodiment.

[0044] Within the scope of this disclosure, the "preloaded position" of the triggering component can refer to a position where the liquid in the atomizer is loaded to prepare for outward spraying (e.g., loaded from the canister into the pump chamber). In this position, without external triggering, the atomizer cannot spontaneously atomize; only through manual operation (e.g., pressing) can the triggering component be activated, causing it to return from the "preloaded position" to the "triggered position," that is, to transition the liquid in the atomizer from a pre-spraying state to a spraying state. In the "triggered position," the atomizer can be operated again (e.g., twisted) to return to the "preloaded position," therefore, the "triggered position" can also be referred to as the initial position.

[0045] First, refer to Figures 1 to 5 , Figure 8 as well as Figure 11 The triggering assembly 1000 for the atomizer includes: a first component 1010, a second component 1020, an actuator 1040, and an anti-reverse stop 1070.

[0046] It can be seen that, Figure 1 The second component 1020 is in the triggered position (also the initial position). Figure 4 and Figure 5 The second component 1020 is in the preload position, while Figure 2 and Figure 3 The second component 1020 is in an intermediate state between the trigger position and the preload position. 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] 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 toward the first direction D1, it can move away from the first component 1010 to a preloaded position. For example, refer to Figures 1 to 5 ,from Figure 1 Starting from the position shown, the second component 1020 is oriented relative to the first component 1010. Figure 1 Rotate clockwise in the middle, and as Figure 2 and Figure 3 As shown, as the second component 1020 rotates, it gradually moves away from the first component 1010; when the second component 1020 rotates further clockwise, it moves to... Figure 4 and Figure 5 The preload position is shown. In the example, the rotational motion between the first component 1010 and the second component 1020 can be converted into relative movement between them by a rack and pinion mechanism or a screw mechanism.

[0048] Actuator 1040 is used to release second component 1020 so that second component 1020 moves from preload position toward first component 1010 to trigger position.

[0049] The anti-reverse stop 1070 is telescopically disposed in the first component 1010 to prevent the second component 1020 from rotating in a second direction D2, opposite to the first direction D1, when the second component 1020 moves to the preload position. (Refer to...) Figure 5 When the second component 1020 is in the preloaded position, the anti-reverse stop 1070 is extended from the first component 1010, and therefore higher than the highest point of the first component 1010, thereby preventing the second component 1020 from moving towards the second direction D2, which is opposite to the first direction D1. Figure 5 Rotate in a counter-clockwise direction. Then refer to... Figure 3 When the second component 1020 rotates further toward the first direction D1 (clockwise) relative to the first component 1010, the anti-reverse stop 1070 is in the state of retracting the first component 1010, thus not affecting the rotation of the second component 1020 toward the first direction D1. Therefore, even when the second component 1020 has moved to the preload position, it can prevent the second component 1020 from rotating in an undesirable reverse direction.

[0050] In some embodiments, the trigger component 1000 may further include a first elastic element 1030 configured to store energy when the second component 1020 moves away from the first component 1010. For example, the first elastic element 1030 may be a spring or other elastic element, as long as it can store energy through elastic deformation. In the example, the first elastic element 1030 (e.g., a spring) may be disposed on the side of the second component 1020 closer to the first component 1010, and undergoes tensile deformation to store energy when the second component 1020 moves away from the first component 1010. When the first elastic element 1030 rebounds, it can push the second component 1020 to the trigger position by tension. Figure 11In the example shown, the first elastic element 1030 (e.g., a spring) can be disposed on the side of the second component 1020 away from the first component 1010. When the second component 1020 moves away from the first component 1010, it undergoes compressive deformation to store energy. When the first elastic element 1030 rebounds, it can push the second component 1020 to the trigger position. Furthermore, the actuator 1040 is configured to prevent the second component 1020 from leaving the preload position when it has moved to the preload position, and is configured to release the second component 1020 upon triggering, so that the second component 1020 moves toward the first component 1010 to the trigger position under the action of the first elastic element 1030. For example, the actuator 1040 may have a surface for blocking the second component 1020, and the position of the actuator 1040 relative to the second component 1020 can change upon triggering, thereby releasing the second component 1020. This achieves a reliable transition of the trigger assembly 1000 between the preload position and the trigger position. Correspondingly, this can improve the ease of use of the atomizer.

[0051] In some embodiments, such as Figures 1 to 5 As shown, actuator 1040 may be disposed at least partially around first component 1010 and / or second component 1020. For example, actuator 1040 may be connected to first component 1010 and disposed partially around the outer periphery of first component 1010; or, actuator 1040 may be connected to second component 1020 and disposed partially around the outer periphery of second component 1020; or, actuator 1040 may be connected to both first component 1010 and second component 1020 and disposed partially around both. Further reference Figure 5 and Figure 6 The actuator 1040 includes a support portion 1042 extending radially inward from the body 1041 of the actuator 1040. For example, the body 1041 of the actuator 1040 may be generally annular in shape, such that its inner periphery can substantially surround a first component 1010 or a second component 1020 having a generally cylindrical outer surface. The support portion 1042 of the actuator 1040 extends radially inward from the annular body 1041.

[0052] from Figures 1 to 5 As can be seen, during the rotation of the second component 1020 relative to the first component 1010, since the actuator 1040 surrounds the first component 1010 and / or the second component 1020, it does not interfere with the rotation of the second component 1020. Instead, as the second component 1020 rotates, the actuator 1040 slides relative to the outer peripheral surface of the second component 1020. When the second component 1020 moves to such a position... Figure 4 and Figure 5In the preloaded position shown, the radially inwardly extending support portion 1042 of the actuator 1040, being closer to the inner side of the body 1041 in the radial direction, can abut against the second component 1020, thereby preventing the second component 1020 from leaving the preloaded position. For example, Figure 5 The upper surface of the support portion 1042 abuts against the lower surface of a portion of the second component 1020, thereby preventing the second component 1020 from moving further downward and leaving the preloaded position.

[0053] In some embodiments, further references Figure 4 and Figure 5 The actuator 1040 can be installed or configured such that when the second component 1020 is disengaged from the first component 1010, the second component 1020 can precisely abut against the support portion 1042 of the actuator 1040. For example, the actuator 1040 can be configured as described above by adjusting the dimensions of the body 1041 of the actuator 1040 (or, in other words, the position of the support portion 1042 of the actuator 1040). In this example, the actuator 1040 can be connected to the first component 1010, and the position of the support portion 1042 of the actuator 1040 can be set at the position where the second component 1020 is precisely 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 support portion 1042, thereby achieving a smooth transition of the second component 1020 from the intermediate state to the preloaded state without causing a small amount of liquid to spray out due to a non-smooth transition.

[0054] In some embodiments, the support portion 1042 may be configured to disengage from the second component 1020 to release the second component 1020 when the actuator 1040 is triggered. For example, the actuator 1040 can be constructed as described above by setting the dimensions of the support portion 1042 of the actuator 1040. In the example, reference continues to... Figures 1 to 5 The inward extension distance of the support portion 1042 does not need to be too large, as long as it can meet the abutment requirements of the second component 1020. Thus, when it is necessary to switch the second component 1020 from the preload position to the trigger position, only a slight movement of the position of the support portion 1042 is required (e.g., in...). Figure 5 By slightly moving the bearing part 104 radially outward, the second part 1020 can be released.

[0055] In some embodiments, such as Figure 4 As shown, the trigger assembly 1000 may also include a second elastic element 1050, which is mechanically coupled to the actuator 1040. When the second component 1020 moves to the preload position, the actuator 1040 moves under the action of the second elastic element 1050 to the position where its bearing portion 1042 abuts against the second component 1020.

[0056] For example, the second elastic element 1050 can be a spring or other elastic element, as long as it can store energy through elastic deformation. In the example, the second elastic element 1050 (e.g., a spring) can be directly or indirectly connected to the actuator 1040, as long as it can be compressed or stretched by the actuator 1040 to produce deformation, and can cause the actuator 1040 to move to the position where its bearing portion 1042 abuts against the second component 1020 through elastic force when triggered. In the example, the second elastic element 1050 can be disposed inside the first component 1010.

[0057] In some embodiments, such as Figure 2 and Figure 3 As shown, before the second component 1020 moves to the preload position, the actuator 1040 abuts against the side wall of the second component 1020 under the action of the second elastic member 1020. Thus, once the second component 1020 moves to the preload position, the actuator 1040 abutting against its inner wall can quickly move further radially inward, thereby causing the bearing portion 1042 to abut against the second elastic member 1020.

[0058] In some embodiments, such as Figure 4 As shown, the trigger assembly 1000 may further include a button connector 1060. One end of the second elastic member 1050 is coupled to the actuator 1040 via the button connector 1060, and the other end of the second elastic member 1050 abuts against the first component 1010. For example, the first component 1010 may have a groove inside for receiving the second elastic member 1050, and the second elastic member 1050 is disposed between the button connector 1060 and the groove. Furthermore, the button connector 1060 may, for example, be connected to the button of an atomizer (…). Figure 5 The button on the atomizer covers the button connector 1060. For example, the user can operate the actuator 1040 by pressing the button, which in turn presses the button connector 1060. Figure 6 As shown, a connecting groove 1061 may be provided in the button connector 1060, and the actuator 1040 may have a connecting rod 1047 that is inserted into the connecting groove. Figure 5 (As shown in the image), the connecting rod can pivot in the connecting groove.

[0059] In some embodiments, continue to refer to Figure 6 The actuator 1040 can be configured in the shape of a bent arm, the bent arm being disposed around the first component 1010 and / or the second component 1020, and the first end 1043 of the bent arm (i.e. Figure 6 The end of the button connector 1060 is used to prevent the second component 1020 from leaving the preloaded position.

[0060] In some embodiments, continue to refer to Figure 6 The second end 1044 of the actuator 1040, opposite the first end 1043, is movably connected to the button connector 1060, and the connection portion 1045 between the first end 1043 and the second end 1044 of the actuator 1040 is pivotally connected to the first component 1010 and / or the second component 1020, so that the actuator 1040 can pivot about the connection portion 1045 by operating the button connector 1060. For example, in Figure 7 The second component is hidden in the middle. It can be seen that the second end 1044 is movably connected to the button connector 1060, and the connection part 1045 is pivotally connected to the shaft on the first component 1010. Thus, when the user presses the button and then the button connector 1060, the second end 1044 of the actuator 1040 moves radially inward (towards the first component 1010), thereby causing the bent-arm shaped actuator 1040 to rotate about its own connection part 1045. As a result, the first end 1043 will move radially outward (away from the first component 1010).

[0061] It will be understood that the connection portion 1045 of the actuator 1040 can also be pivotally connected to the second component 1020, which will not be described in detail here.

[0062] In some embodiments, the first component 1010 may include a first helical portion 1011, and the second component 1020 may include a second helical portion 1021, wherein the helical end face of the second helical portion 1021 can engage with the helical end face of the first helical portion 1011. Furthermore, the first helical portion 1011 and the second helical portion 1021 are configured such that when the second component 1020 is aligned with the first component 1010 along the engaging first helical portion 1011 and the second helical portion 1021 in a first direction D1 (e.g., ...) Figures 1 to 5 When rotated clockwise, it can move to the preload position. In other words, the helical end faces of the first helical part 1011 and the second helical part 1021 can be combined together, for example, the high part of one helical part can be combined with the low part of the other helical part, and the two can achieve relative rotation. During the relative rotation (e.g., from clockwise direction), the helical end faces of the first helical part 1011 and the second helical part 1021 can be combined together, for example, the high part of one helical part can be combined with the low part of the other helical part, and the two can achieve relative rotation. Figures 1 to 3 And then Figure 5 During the process, due to the spiral end face, the second spiral part 1021 can gradually move away from the first part 1010, thereby gradually reaching the preload position.

[0063] In some embodiments, reference Figure 4 or Figure 5The first helical portion 1011 and / or the second helical portion 1021 can be configured such that, when the second component 1020 moves to the preload position, the second helical portion 1021 disengages from the first helical portion 1011. Disengagement of the second helical portion 1021 from the first helical portion 1011 means that there is no contact between them, thereby allowing the second component 1020 to smoothly return to its initial position, i.e., the trigger position, when it is released.

[0064] In some embodiments, the actuator 1040 may be configured to abut against the second helical portion 1021 to prevent the second component 1020 from leaving the preloaded position when the second helical portion 1021 disengages from the first helical portion 1011. (Continue referring to...) Figure 4 or Figure 5 As can be seen, the second spiral section 1021 has disengaged from the first spiral section 1011 at this time. In this example, the liquid in the atomizer has been fully loaded and is in a preloaded state. In order to maintain the trigger component 1000 in this preloaded state, the second spiral section 1021, which has disengaged from the first spiral section 1011, is abutted by the actuator 1040 (e.g., the support portion 1042 of the actuator 1040).

[0065] In some embodiments, reference Figure 1 When the second component 1020 moves to the trigger position (initial position), the second spiral part 1021 (as shown) Figure 5 The spiral end face (as seen in the image) and the first spiral portion 1011 (as shown in the image) Figure 5 The spiral end faces (as seen in the diagram) are in contact. When the actuator 1040 is triggered, the actuator 1040 no longer abuts against the second spiral portion 1021 of the second component 1020. The second component 1020 can return to the triggered position (initial position) under the action of the first elastic member 1030. At this time, the spiral end face of the second spiral portion 1021 is in contact with the spiral end face of the first spiral portion 1011, which can form a relatively complete columnar shape and reduce space occupation.

[0066] In some embodiments, the first helical portion includes two centrally symmetrical first helical portions 1011, the second helical portion includes two centrally symmetrical second helical portions 1021, and the actuator 1040 includes a first actuator 1441 and a second actuator 1442 disposed on both circumferential sides of the first component 1010 and / or the second component 1020, the first actuator 1441 and the second actuator 1442 being respectively used to abut against a corresponding second helical portion of the two second helical portions. Figure 7As shown, the first actuator 1441 and the second actuator 1442 are respectively disposed on both sides of the first component 1010. When the second component 1020 is in the preload position, the first actuator 1441 and the second actuator 1442 can respectively support the two second helical parts 1021, thereby improving the load-bearing stability of the second component 1020.

[0067] In some embodiments, such as Figure 6 As shown, the actuator 1040 may include a limiting protrusion 1046, which is disposed adjacent to the support portion 1042 and protrudes from the support surface of the support portion 1042. The limiting protrusion 1046 is used to prevent the second component 1020 from rotating toward the first direction D1 when the support portion 1042 abuts against the second helical portion 1021. Figure 4 As shown, at this time, the second component 1020 is in the preloaded position, the bearing part 1042 abuts against the second spiral part 1021, and the limiting protrusion 1046 prevents the second component 1020 from moving towards the first direction D1. Figure 4 The rotation (clockwise) between the second component 1020 and the first component 1010 can prevent undesirable rotation toward the first direction D1.

[0068] In some embodiments, a limiting step 1022 is provided at the end of the second spiral portion 1021 of the second component 1020, and the limiting protrusion 1046 of the actuator 1040 blocks the rotation of the second component 1020 toward the first direction D1 by abutting against the limiting step 1022.

[0069] In some embodiments, the triggering component 1000 may further include an anti-reverse stop 1070, which is telescopically disposed in the first component 1010 to prevent the second component 1020 from rotating toward a second direction D2 opposite to the first direction D1 when the second component 1020 moves to the preload position. (Refer to...) Figure 5 When the second component 1020 is in the preloaded position, the anti-reverse stop 1070 is extended from the first component 1010, and therefore higher than the highest point of the first component 1010, thereby preventing the second component 1020 from moving towards the second direction D2, which is opposite to the first direction D1. Figure 5 Rotate in a counter-clockwise direction. Then refer to... Figure 3 When the second component 1020 rotates further toward the first direction D1 (clockwise) relative to the first component 1010, the anti-reverse stop 1070 is in the state of retracting the first component 1010, so it does not affect the rotation of the second component 1020 toward the first direction D1.

[0070] refer to Figure 8 , Figure 8This is a schematic diagram illustrating an anti-retraction stop for a trigger assembly of an atomizer according to an exemplary embodiment. In some embodiments, the anti-retraction stop 1070 may include a beveled portion 1071 configured to retract at least partially into the first component 1010 under the compression of the second component 1020. For example, the beveled portion 1071 may substantially mate with the helical end face of the second helical portion 1021 of the second component 1020, and the beveled portion 1071 may also have a substantially helical end face. The anti-retraction stop 1070 retracts at least partially into the first component 1010, provided that the anti-retraction stop 1070 does not impede the rotation of the second component 1020 toward the first direction D1.

[0071] In some embodiments, the anti-reverse stop 1070 may be configured such that, during the period when the second component 1020 is disengaged from the preloaded position, the anti-reverse stop 1070 extends at least partially from the first component 1010, such that the straight portion 1072 of the anti-reverse stop 1070 opposite the inclined portion 1071 can block the rotation of the second component 1020 toward the second direction D2. For example, when the second component 1020 disengages from the preloaded position... Figure 3 The position shown is towards Figure 5 During the position change shown, the anti-reverse stop 1070 extends at least partially from the first component 1010, such that its straight portion 1072 blocks the rotation of the second component 1020 toward the second direction D2 (counterclockwise direction).

[0072] In some embodiments, further references Figure 8 The anti-reverse stop 1070 may include a chamfered face 1073, which may be located at the first end of the beveled portion 1071. During the rotation and downward pressure of the second component 1020 on the anti-reverse stop 1070, the first end of the beveled portion 1071 is the last part to contact the second component 1020 relative to the other parts of the beveled portion 1071. Therefore, the chamfered face 1073 facilitates a smooth transition when the second component 1020 leaves the anti-reverse stop 1070, thereby reducing jamming.

[0073] In some embodiments, further references Figure 8The anti-reverse stop 1070 may include a stepped portion 1074, which may be located at the second end of the inclined portion 1071. During the rotation of the second component 1020 and downward pressure on the anti-reverse stop 1070, the second end of the inclined portion 1071 contacts the second component 1020 first relative to other parts of the inclined portion 1071. Therefore, providing the stepped portion 1074 helps prevent the side 1075 of the anti-reverse stop 1070 from undesirably obstructing the second component due to excessive height, and correspondingly provides a certain installation tolerance for the amount of extension of the anti-reverse stop 1070 from the first component 1010.

[0074] In some embodiments, such as Figure 8 As shown, the trigger assembly 1000 may further include an anti-reverse elastic member 1080, and the first component 1010 may further include a groove for receiving the anti-reverse stop member 1070. The anti-reverse elastic member 1080 is disposed between the anti-reverse stop member 1070 and the groove, providing elastic force for the anti-reverse stop member 1070 to extend out of the groove. When the second component 1020 no longer presses against the anti-reverse stop member 1070, the anti-reverse stop member 1070 can extend out of the first component 1010 under the elastic force of the anti-reverse elastic member 1080 to block the rotation of the second component 1020 toward the second direction D2.

[0075] This disclosure provides an atomizer. The atomizer includes a triggering component 1000 of this disclosure, which is used to trigger the atomizer to eject atomized fluid.

[0076] The following will combine Figures 9 to 11 The atomizer disclosed herein will be further described. Figure 9 This is a perspective view of an atomizer according to an exemplary embodiment; Figure 10 This figure illustrates a side view of an atomizer according to an exemplary embodiment; and Figure 11 This is an illustration based on an exemplary embodiment. Figure 10 Cross-sectional view of the atomizer at section AA.

[0077] like Figures 9 to 11 As shown, the atomizer 2000 may include an upper housing 2010, a lower housing 2020, a button 2030 disposed in the upper housing portion, and a delivery tube seat 2040 disposed in the lower housing 2020.

[0078] In some embodiments, the first component 1010 may be configured as the upper housing 2010 of the atomizer 2000, and the second component 1020 may be configured as the delivery tube seat 2040 of the atomizer 2000, and the delivery tube seat 2040 may be configured to rotate with the rotation of the lower housing 2020 of the atomizer 2000. For example, the upper housing 2010 and the lower housing 2020 may rotate relative to each other, and the delivery tube seat 2040 is coupled to the lower housing 2020. By rotating the lower housing 2020 relative to the upper housing 2010, the delivery tube seat 2040 may rotate 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 may rotate relative to the first component 1010, and the second component 1020 may move away from the first component 1010 to a preload 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 atomization.

[0079] In some embodiments, when a user presses button 2030, button 2030 can trigger actuator 1040 via, for example, button connector 1060. Actuator 1040 then releases delivery seat 2040, causing delivery seat 2040 to move toward upper housing 2010 to a triggered position under the action of first elastic member 1030. During this process, the volume of the pumping chamber decreases under the squeezing action of delivery seat 2040, increasing the pressure within the pumping chamber, thereby atomizing and spraying the liquid within the pumping chamber through an outlet above upper housing 2010.

[0080] This improves the ease of use of atomizers.

[0081] In some embodiments, the atomizer 2000 may include a main rotating body 2050 located inside the lower housing 2020 and disposed outside the delivery tube seat 2040. The main rotating body 2050 can transmit the rotation of the lower housing 2020 to the delivery tube seat 2040; in other words, when the main rotating body 2050 rotates, the delivery tube seat 2040 also rotates. Furthermore, when the delivery tube seat 2040 is released and moves toward the upper housing 2010, the main rotating body 2050 does not move upward with the delivery tube seat 2040.

[0082] In the example, the actuator 1040 can be longitudinally positioned using both the upper housing 2010 and the main rotating body 2050. For example, refer to... Figure 7 One end face of the actuator may abut against the rib 1012 of the first component 1010. (Back) Figure 11 Accordingly, it can be seen that the lower end face of the rib of the upper housing 2010 abuts against the upper end face of the actuator 1040. Furthermore, referring again... Figure 7The actuator may have a longitudinal positioning protrusion 1048, returning to Figure 11 Accordingly, it can be seen that the upper end face of a portion of the main rotating body 2050 can abut against the lower end face of the longitudinal positioning protrusion 1048 of the actuator 1040. Thus, the upper housing 2010 and the main rotating body 2050 can perform longitudinal positioning of the actuator 1040.
