Description

[Technical field]

[0001] The present disclosure relates to a trigger assembly for use in an atomizer, which can be used, for example, to atomize and / or spray a medical fluid. [Background technology]

[0002] In the related art, a container in an atomizer (also called a sprayer) contains the liquid to be atomized or sprayed, and during the movement stroke of the container relative to a jet assembly (e.g., a pump), the liquid in the container is atomized and sprayed as the atomized liquid from the nozzle of the jet assembly. However, the triggering of such an atomizer is generally not stable, so the liquid atomization and spraying process is not always smooth. Also, when the atomizer is vibrated, shaken, or, for example, accidentally slips off, the internal assembly may move automatically undesirably, which causes the atomizer to be triggered automatically and unintentionally.

[0003] Such inadvertent automatic triggering of the atomizer is undesirable and not only results in unnecessary waste of liquid, but may also cause the atomizer to leak or even break or fail when not in use by the user. Summary of the Invention

[0004] An object of the present disclosure is to provide a trigger assembly for use in an atomizer, which can control whether the atomizer is triggered by switching between a locked position and an unlocked position, thereby preventing undesired automatic triggering of the atomizer and enhancing the stability of the atomizer.

[0005] According to a first aspect of the present disclosure, there is provided a trigger assembly for use in an atomizer, the trigger assembly including a trigger ring and a transport tube seat, wherein the trigger ring includes a ring body and a first locking portion disposed on the ring body, and at least one surface of the first locking portion forms a first locking surface, the transport tube seat includes a tube seat body and a second locking portion disposed on the tube seat body, and at least one surface of the second locking portion forms a second locking surface, the trigger assembly has a locked position and an unlocked position, in the locked position, the first locking surface is in intimate contact with the second locking surface such that the trigger ring and the transport tube seat are stopped against each other, and in the unlocked position, the first locking surface is not in contact with the second locking surface such that the transport tube seat can move axially relative to the trigger ring.

[0006] The trigger assembly according to the present disclosure can effectively prevent the atomizer from being unintentionally triggered accidentally, for example, in the process of the atomizer accidentally sliding down, the trigger assembly can lock the relative moving parts of the atomizer, so that the atomizer is stably positioned in the untriggered position. What is more, these relative moving parts are locked to each other, i.e., in the locked position of the trigger assembly, the trigger ring locks the movement of the transport tube seat, and at the same time, the transport tube seat also locks the movement of the trigger ring.

[0039] The technical solutions in the embodiments of the present disclosure will be described below clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without any creative effort are all within the scope of protection of the present disclosure.

[0040] It should be explained that all directional indications (e.g., up, down, left, right, front, back, etc.) in the embodiments of the present disclosure are merely for interpreting the relative positional relationships, movement conditions, etc. between each part in a certain posture (as shown in the drawings), and if the posture changes, the directional indications will change accordingly.

[0041] In the present disclosure, unless otherwise clearly specified and limited, the terms "connected", "fixed", etc. should be understood in a broad sense, for example, unless otherwise clearly limited, it may be directly connected, indirectly connected via an intermediate medium, internal communication between two elements, or an interactive relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present disclosure according to the specific situation.

[0042] In this disclosure, unless otherwise stated, all numbers used in the specification and claims expressing parameters of parts, technical effects, etc., should be understood to be modified in any case by the term "approximately" or "approximately". Thus, unless otherwise indicated, the numerical parameters set forth in the following specification and the appended claims are approximate values. For those skilled in the art, each numerical parameter can vary depending on the desired properties and effects to be obtained by the present disclosure, and should be interpreted based on the number of significant digits and conventional rounding methods, or as understood by those skilled in the art.

[0043] In this disclosure, the terms used in the description of the various examples are intended to describe specific examples only and are not intended to be limiting. Unless otherwise clearly indicated by the context, the elements may be one or more unless the number of elements is specifically limited. In addition, the term "and / or" used in this disclosure covers any and all possible combinations of the listed items.

[0044] In the scope of this disclosure, an "atomizer" (also called a "nebulizer") is a device for atomizing a liquid. Generally, an atomizer is used to atomize a fluid (e.g., a medicinal liquid or the like) and propel the atomized fluid to some treatment site of a user (e.g., a patient). Since the atomizer contains a medicinal liquid, the stability of the atomizer is extremely important.

[0045] In the related art, the atomizer can be operated by mechanical means, for example, by pressing a switch or rotating a switch. However, the locking of these switches when the atomizer is not in use may not be stable. Furthermore, when there is no need for atomization, the atomizer may undergo some bumps or shaking, and may even slip down unexpectedly from a high place, which may cause the medicinal liquid in the atomizer to shake and cause the relative movement of parts in the atomizer to undesirably atomize the liquid. It can be understood that in this situation, the medicinal liquid does not reach the area to be treated, so this undesirable atomization trigger is ineffective, and what's worse, this undesirable atomization trigger may be harmful, because the unexpectedly ejected atomized liquid may flow around and accumulate in the atomizer, which may impair the function or break down the parts of the atomizer over time.

[0046] In view of this, the present disclosure provides an improved trigger assembly that is attached to an atomizer and is preferably operable to interface with a push switch and / or a rotary switch of the atomizer to control active triggering of the atomizer and / or prevent inactive triggering of the atomizer by switching the trigger assembly between locked and unlocked positions.

[0047] In the scope of the present disclosure, the term "trigger assembly" refers to an assembly for controlling the trigger of an atomizer, for example, an assembly that can control and / or prevent the atomization or spraying operation of the atomizer. In the present disclosure, the trigger assembly can include, for example, a trigger ring 1000 and a transport tube seat 2000, the specific structures of which will be described in detail below with reference to Figures 1 to 4 and Figures 5 to 8, respectively. In addition, the arrangement of the trigger assembly in the atomizer can be described in detail with reference to Figures 17 to 19, for example.

[0048] It should be understood that the trigger assembly may include other elements in addition to the trigger ring 1000 and transport tube seat 2000, so long as the trigger assembly provides control and / or prevention of the trigger function. What is important is that the trigger assembly has a locked position(s) and an unlocked position(s) and is capable of being switched between these positions.

[0049] In the scope of the present disclosure, the "locked position" of the trigger assembly refers to a position in which the atomizer is locked, i.e., the atomizer cannot be operated without manual action. In other words, when the trigger assembly is in the "locked position", the atomizer can only be operated by manual action to perform atomization or spraying. In the present disclosure, the "locked position" of the trigger assembly can also refer to a position in which the trigger ring 1000 and the transport tube seat 2000 act as mutual stoppers. As an example, the "mutual stopper" of the trigger ring 1000 and the transport tube seat 2000 can mean, for example, that the trigger ring 1000 prevents the transport tube seat 2000 from moving, for example, in the vertical direction, and at the same time, the transport tube seat 2000 prevents further movement of the trigger ring 1000, for example, translation in the horizontal and / or vertical directions. The "locked position" will be further described with reference to FIGS. 9 to 11 below.

[0050] In the scope of the present disclosure, the "unlocked position" of the trigger assembly refers to a position where the atomizer is not locked, i.e., the atomizer can be operated. In other words, when the trigger assembly is in the "unlocked position", the parts of the atomizer (e.g., the trigger ring 1000 and the delivery tube seat 2000) can move relative to each other without manual operation to achieve the effect of atomization and / or the effect of spraying the atomized liquid. It can be understood that the "unlocked position" of the trigger assembly is a concept corresponding to the above-mentioned "locked position", and the trigger assembly is in the unlocked position as long as the atomizer is not locked. Therefore, the trigger assembly can have, for example, multiple "unlocked positions", and the trigger assembly can be switched between a locked position and an unlocked position, or between multiple unlocked positions. In the process of such switching of the trigger assembly, the atomizer can realize switching among an initial position, a pre-trigger position, and a triggered position. The "unlocked position" will be further described with reference to the following Figures 12-14 and 15-16.

[0051] First, a trigger ring 1000 according to one embodiment of the present disclosure will be described with reference to FIGS. 1 to 4. The trigger ring 1000 may include a ring body 1200 and a first locking portion (here, for example, a locking protrusion 1100). The locking protrusion 1100 protrudes downward from the bottom side of the ring body 1200. It can be understood that the drawings show only one locking protrusion 1100 protruding downward from the bottom of the ring body 1200, but the number and arrangement of the locking protrusions 1100 are not limited thereto. For example, the trigger ring 1000 may include a plurality of locking protrusions 1100, for example, two or three locking protrusions 1100 are provided on one side thereof, and these locking protrusions 1100 are preferably set in an array at equal angles along the circumferential direction, thereby realizing, for example, multi-stage locking and unlocking of the trigger assembly. For example, when two locking protrusions 1100 are provided, the two locking protrusions 1100 are arranged in an array along the circumference of the ring body 1200 at an angle of 180°.

[0052] As another example, the locking protrusions 1100 can be installed on both sides of the ring body 1200. In such a case, the locking protrusions 1100 on the upper and lower sides are, for example, installed offset from each other and engage with and interlock with the locking notches 2100 installed on the upper and lower sides of the trigger ring 1000.

[0053] As can be seen from the drawings, there are several rib structures on both sides of the ring body 1200, respectively, for interconnecting or mating with other parts. For example, two ribs 1300 on the ring body 1200 form a groove 1310, which can mating with a rotating part of an atomizer, thereby restricting the rotation of the ring body 1200 so that the ring body 1200 can only move in translation.

[0054] The locking protrusion 1100 may include a first locking surface 1110, which may be, for example, a lower inclined surface of the locking protrusion 1100. As can be seen, the first locking surface 1110 is an inclined surface that is inclined in all three-dimensional directions, that is, the first locking surface 1110 is not only inclined with respect to the horizontal plane (X'Y' plane), but also inclined with respect to the vertical planes (Z'Y' plane and X'Z' plane). In other words, the first locking surface 1110 is both an outward surface in the radial direction of the triggering ring 1000 and an outward surface in the axial direction of the triggering ring 1000.

[0055] As one example, the angle β' between the normal direction F' of the first locking surface 1110 and the first horizontal direction X' of the triggering ring 1000 is in the range of 135° to 178°, preferably in the range of 155° to 175°, or the angle β' is in the range of 150° to 189°, and particularly preferably 168.5°. The angle γ' between the normal direction F' of the first locking surface 1110 and the second horizontal direction Y' of the triggering ring 1000 is in the range of 65° to 90°, preferably in the range of 65° to 89°, preferably in the range of 70° to 85°, and particularly preferably 78.5°, and the angle α' between the normal direction F' of the first locking surface 1110 and the vertical direction Z' of the triggering ring 1000 is in the range of 115° to 145°, preferably in the range of 120° to 140°, and particularly preferably 130°. In the present disclosure, the "first horizontal direction X'" and the "second horizontal direction Y'" of the triggering ring 1000 respectively correspond to the radial directions of the triggering ring 1000, and here, the second horizontal direction Y' is also the trigger direction of the triggering ring 1000, that is, the direction in which the triggering ring 1000 receives a thrust and moves horizontally when a user presses a push switch. The "vertical direction Z'" of the triggering ring 1000 corresponds to the axial direction of said triggering ring 1000. These directions X', Y' and Z' are labelled with reference to the coordinate system in Figures 1 to 3.

[0056] Here, such a three-dimensionally inclined arrangement of the first locking surface 1110 is very advantageous because, on the one hand, when the first locking surface 1110 mates with the second locking surface 2110 located in the locking notch 2100, the operating force to switch the trigger assembly from the locked position to the unlocked position is not too large, otherwise the trigger assembly may be stuck in the unlocked position, or the user may need to exert too much force to release the interlock between the trigger ring 1000 and the transport tube seat 2000. On the other hand, when the trigger assembly needs to be locked, for example to keep the atomizer in a pre-triggered state, the three-dimensionally inclined first locking surface 1110 can effectively abut the second locking surface 2110 in multiple dimensions to prevent further vertical upward movement and / or rotational movement. As can be seen, the three-dimensionally inclined first locking surface 1110 plays a desired balancing role between preventing locking and preventing automatic atomization.

[0057] In a further example, Fig. 3 shows a partial enlarged view of R in Fig. 2. From this, it can be seen the projection of the first locking surface 1110 onto a horizontal plane, which is set here to be approximately trapezoidal. Here, the angle A' between the projection of the first locking surface 1110 and the first radial direction X' of the triggering ring 1000 is in the range of 5°-50°, preferably in the range of 5°-30°, for example about 15°, and the angle B' between the projection and the second radial direction Y' of the triggering ring 1000 is in the range of 3°-60°, preferably in the range of 5°-20°, for example about 20°. It is particularly advantageous if the angle A' is larger than the angle B' (for example, the angle A' is 5° to 10° larger than the angle B'), so that the relative sliding between the locking protrusion 1100 and the locking notch 2100 is gentle and stable in the process of the unlocking assembly moving from the locked position to the unlocked position. Also advantageously, the angle C' between the projection of the first locking surface 1110 onto a vertical plane and the axial direction Z' of the triggering ring 1000 is in the range of 15° to 80°, preferably in the range of 30° to 50°.

[0058] The locking protrusion 1100 further includes a guide surface 1120, which is the bottom surface of the locking protrusion 1100 here and is set horizontally. Of course, the guide surface 1120 may be set slightly inclined with respect to the horizontal plane. During the position conversion of the trigger assembly, the guide surface 1120 contacts the bottom of the groove of the locking notch 2100, which makes the conversion process smoother.

[0059] Additionally, the locking protrusion 1100 further includes a transition surface 1130 for limiting rotational movement of the triggering ring 1000 such that the triggering ring 1000 can only move in translation when constrained by the transition surface 1130 .

[0060] Hereinafter, the transport tube seat 2000 according to one embodiment of the present disclosure will be described in detail with reference to Figs. 5 to 8. The transport tube seat 2000 can include a barrel-shaped tube seat body 2200 and a second locking portion (here, for example, a locking notch 2100 recessed and installed on one side of the tube seat body 2200) installed on the tube seat body. Although two locking notches, namely, the locking notch 2100 and the locking notch 2100', are shown in the figure, it should be understood that the number and arrangement of the locking notches 2100 are not limiting, and any number of locking notches 2100 can be installed on the upper wall of the tube seat body 2200 as required, and different numbers of second locking surfaces 2110 can be installed on one or both sides of the locking notches 2100. The flexible installation possibility of the locking notches 2100 allows the movement level of the unlocking assembly to be adapted as required.

[0061] In this embodiment, the locking protrusion 1100 is an example of the first locking portion, and the locking notch 2100 is an example of the second locking portion, and it is further conceivable that in another embodiment, the first locking portion is configured in the form of a locking notch, and the second locking portion is configured in the form of a locking protrusion. It should be understood that, as long as the first locking portion and the second locking portion can realize the interlocking and unlocking functions, the arrangements of the locking protrusion and the locking notch can be interchanged or selected and utilized as required.

[0062] At least one wall of the locking notch 2100 constitutes a second locking surface 2110, which fits with the first locking surface 1110, i.e., when the trigger assembly is in the locked position, the second locking surface 2110 and the first locking surface 1110 abut against each other. As the trigger ring 1000 moves, for example, by the action of a push switch, the first locking surface 1110 slides over the second locking surface 2110 in close contact therewith, and when it slides past the second locking surface 2110, the trigger assembly enters the unlocked position.

[0063] Similar to the first locking surface 1110, the second locking surface 2110 is also a three-dimensionally inclined surface, i.e., the second locking surface 2110 is not only inclined with respect to the horizontal plane (XY plane), but also inclined with respect to the vertical planes (ZY plane and XZ plane). In other words, the second locking surface 2110 is both a surface facing inward in the radial direction of the transport tube seat 2000 and a surface facing inward in the axial direction of the transport tube seat 2000.

[0064] As one example, the angle β between the normal direction F of the second locking surface 2110 and the first horizontal direction X of the transport tube seat 2000 is in the range of 55° to 90°, preferably in the range of 67° to 87°, or preferably in the range of 60° to 90°, and particularly preferably 77°, the angle γ between the normal direction F of the second locking surface 2110 and the second horizontal direction Y of the transport tube seat 2000 is in the range of 145° to 185°, preferably in the range of 150° to 180°, preferably in the range of 155° to 178°, and particularly preferably 167°, and here, the angle α between the normal direction F of the second locking surface 2110 and the vertical direction Z of the transport tube seat 2000 is in the range of 30° to 60°, preferably in the range of 40° to 55°, and particularly preferably 46.3°. In the present disclosure, the "first horizontal direction X" and "second horizontal direction Y" of the transport tube seat 2000 correspond to the radial direction of the transport tube seat 2000, and the "vertical direction Z" of the transport tube seat 2000 corresponds to the axial direction of the transport tube seat 2000. These directions X, Y, and Z are labeled with reference to the coordinate systems in Figures 5 to 8.

[0065] Here, such a three-dimensionally inclined arrangement of the second locking surface 2110 is very advantageous because, on the one hand, when the second locking surface 2110 is mated with that installed on the first locking surface 1110, the operating force to switch the trigger assembly from the locked position to the unlocked position is not too large, otherwise the trigger assembly may be stuck in the unlocked position, or the user needs to exert too much force to release the interlock between the trigger ring 1000 and the transport tube seat 2000. On the other hand, when the trigger assembly needs to be locked, for example to keep the atomizer in a pre-triggered state, the three-dimensionally inclined second locking surface 2110 can effectively abut the first locking surface 1110 in multiple dimensions and prevent its further movement. As can be seen, the three-dimensionally inclined second locking surface 2110 plays a desired balancing role between preventing locking and preventing automatic atomization.

[0066] In a further example, Fig. 7 shows an enlarged view of a portion S in Fig. 6. From this, it can be seen the projection of the second locking surface 2110 onto a horizontal plane, which is now approximately a parallelogram. Here, the angle A between the projection of the second locking surface 2110 onto the horizontal plane and the first radial direction X of the transport tube seat 2000 is in the range of 5° to 60°, preferably in the range of 10° to 45°, for example 30°, and the angle B between the projection of the second locking surface 2110 onto the horizontal plane and the second radial direction Y of the transport tube seat 2000 is in the range of 5° to 60°, preferably in the range of 5° to 25°, for example 15°. It is particularly advantageous if the angle A is greater than the angle B (for example, the angle A is 5° to 10° greater than the angle B), which allows the stroke of the unlocking assembly moving from the locked position to the unlocked position to be controlled. Moreover, the angle C between the projection of the second lock surface 2110 onto the vertical plane and the axial direction Z of the transportation pipe seat 2000 is within a range of 15° to 80°, and preferably within a range of 35° to 55°.

[0067] The locking notch 2100 may further include a groove bottom contacting the guide surface 1120 and two side walls, and the second locking surface 2110 is installed on one wall. As can be further seen from the drawing, in a preferred embodiment, the locking notch 2100 further includes a guide slope 2120, which has a common edge with the second locking surface 2110, and the sum of the radial dimension d1 of the second locking surface 2110 and the radial dimension of the guide slope 2120 is equal to the radial thickness dimension d2 of the tube seat body 2200 on that side. The guide slope 2120 is also configured as a parallelogram shape, and is arranged in the same position as the second locking surface 2110 with an equal angle along the approximately circumferential direction. Here, the guide bevel 2120 is used, for example, to guide the unlocking assembly to the unlocked position, thereby preventing the unlocking ring from moving too far away due to excessive free movement if the unlocking assembly is suddenly moved away from the locked position. In the embodiment in which the guide bevel 2120 is provided, the radial dimension d1 of the second locking surface 2110 is greater than half the radial thickness dimension d2 of the transport tube seat 2000 on that side, and preferably greater than two-thirds the radial thickness dimension d2 of the transport tube seat 2000 on that side. The horizontal projection of the guide bevel 2120 is shown in FIG. 7, and the angle between the horizontal projection and the second radial direction Y of the transport tube seat 2000 is equal to the angle B between the horizontal projection of the second locking surface 2110 and the second radial direction Y of the transport tube seat 2000. Preferably, the angle D between the projection of the guide slope 2120 onto the horizontal plane and the first radial direction X of the transport tube seat 2000 is within a range of 20° to 80°, preferably within a range of 40° to 65°, for example, 45°. Preferably, the angle between the normal direction of the guide slope 2120 and the first horizontal direction X of the transport tube seat 2000 is within a range of 135° to 160°, and the angle between the normal direction of the guide slope 2120 and the second horizontal direction Y of the transport tube seat 2000 is within a range of 115° to 135°, where the angle between the normal direction of the guide slope 2120 and the vertical direction Z of the transport tube seat 2000 is within a range of 115° to 135°.

[0068] It can be appreciated that the guide ramp 2120 is not required, but is merely a preferred arrangement, and in the absence of the guide ramp 2120, the second locking surface 2110 can occupy the entire radial dimension of the wall thickness.

[0069] The transport tube seat 2000 further includes a connection plate 2500 for, for example, matingly connecting with other components of the sprayer, such as the container 4000, the rotating member 6000, or the housing 8000. The transport tube seat 2000 further includes a transport tube 2400 that is used to transport the liquid contained in the container 4000 to the ejection cavity of the spray.

[0070] In a preferred embodiment, an elastic component, such as a spring 5000, may be installed at the bottom of the transport tube seat 2000. The spring 5000 exerts an upward thrust on the transport tube seat 2000 all the time, so that the transport tube seat 2000 can move upward, i.e., axially, immediately after the trigger assembly leaves the locking position. When the outer diameter of the transport tube seat 2000 is equal to or smaller than the inner diameter of the trigger ring 1000, the transport tube seat 2000 can pass through the trigger ring 1000 upward by the action of the spring 5000, and when a downward force is applied to the transport tube seat 2000, the transport tube seat 2000 can also overcome the elastic force and move downward and return to the locking position. It should be understood that the spring 5000 is not necessary and is a preferred component of the atomizer. Other alternative components, such as a button, may also be envisaged, as long as they can provide the transport tube seat 2000 with an axial upward thrust.

[0071] The inside of the transport tube seat 2000 may further include a spiral portion 2600 disposed on the upper surface of the protrusion radially inward from the inner wall of the tube seat body 2200. When the transport tube seat 2000 is disposed in an atomizer, the spiral portion 2600 may be fitted with the corresponding spiral portion 7100 of the suction nozzle 7000, for example. When the transport tube seat 2000 rotates, the transport tube seat 2000 may move vertically, i.e., in the axial direction. In the present disclosure, during the downward movement of the transport tube seat 2000, the transport tube seat 2000 may perform downward movement accompanied by rotation due to the action of the spiral portion, that is, a compound movement of rotation and downward translation at the same time, but during the upward movement of the transport tube seat 2000, the transport tube seat 2000 may perform only upward translation without any rotation.

[0072] In the present disclosure, the trigger assembly may be, for example, composed of the trigger ring 1000 and the delivery tube seat 2000, and the trigger assembly may be moved between a locked position and an unlocked position to realize prevention of automatic triggering of the atomizer. Hereinafter, one locked position of the trigger assembly according to one embodiment of the present disclosure will be described in detail with reference to Figures 9 to 11, and two unlocked positions of the trigger assembly according to one embodiment of the present disclosure will be described in detail with reference to Figures 12 to 16, where the first unlocked position of the trigger assembly is shown in Figures 12 to 14, and the second unlocked position of the trigger assembly is shown in Figures 15 to 16.

[0073] 9-11 show the trigger assembly in a locked position, which corresponds to, for example, a pre-trigger position of the atomizer, i.e., the atomizer housing 8000 is rotated so that the transport tube seat 2000 moves downward (preferably with rotation) along the helical surface to a position where the locking protrusion 1100 and the locking notch 2100 are mutually stopped. In the pre-trigger position, the mutual stop of the locking protrusion 1100 and the locking notch 2100 prevents any part between them from moving without manual operation, so that the atomizer is stable, i.e., accidental triggering is prevented.

[0074] In this locked position, the first locking surface 1110 of the locking protrusion 1100 abuts against the second locking surface 2110 of the locking notch 2100, so as to realize a mutual stop between the trigger ring 1000 and the transport tube seat 2000. As described above, since not only the first locking surface 1110 but also the second locking surface 2110 are three-dimensional inclined surfaces, such a mutual stop is very reliable, and it can be ensured that the atomizer will not be unlocked by accidental operation (for example, the atomizer is impacted or accidentally slips off).

[0075] In an advantageous embodiment, in the locked position, the trigger ring 1000 is arranged non-coaxially with respect to the transport pipe seat 2000, i.e. they are arranged eccentrically.

[0076] In order to convert the trigger assembly to the unlocked position, a horizontal thrust may be applied to the trigger ring 1000. The horizontal thrust may be applied indirectly to the trigger ring 1000 by manually pressing a push switch, or may be applied directly to the trigger ring 1000.

[0077] As can be appreciated, the trigger assembly immediately moves to the unlocked position when it is moved away from the locked position, in other words, unless the atomizer needs to be locked to prevent accidental triggering, the trigger assembly can be moved to the unlocked position immediately, thereby facilitating free operation of the atomizer.

[0078] 12 to 14 and 15 to 16 show the trigger assembly in a first unlocked position and a second unlocked position, respectively. Here, the terms "first unlocked position" and "second unlocked position" are used to distinguish between them for the sake of clarity only, and do not represent any sequential relationship between them.

[0079] The first unlocked position shown in Figures 12-14 may be a transient state or a stable state, since the transport tube seat 2000 can move axially relative to the trigger ring 1000 when the first locking surface 1110 is no longer in contact with the second locking surface 2110. And as described above, since the trigger ring 1000 is pushed horizontally so that the trigger assembly moves away from the locked position, in the first unlocked position, the trigger ring 1000 is coaxially disposed relative to the transport tube seat 2000, i.e., there is no eccentricity between them. In this case, if the outer diameter of the transport tube seat 2000 is equal to or smaller than the inner diameter of the trigger ring 1000, the transport tube seat 2000 can pass through the trigger ring 1000 to reach the second unlocked position.

[0080] A thrust mechanism such as a spring 5000 can be installed under the transport tube seat 2000 to encourage the transport tube seat 2000 to pass through the trigger ring 1000. When the spring 5000 is installed, when the trigger ring 1000 is pressed horizontally to cause the first locking surface 1110 to slide through the second locking surface 2110, the transport tube seat 2000 immediately moves upward due to the action of the spring 5000, so the first unlocked position is a transient state. When the spring is not installed, even if the trigger ring 1000 is pressed horizontally to cause the first locking surface 1110 to slide through the second locking surface 2110, the transport tube seat 2000 does not immediately receive a force and move upward, so the first unlocked position is a relatively stable state. In this case, other passive operating structures such as a button can be considered.

[0081] After the transport tube seat 2000 passes through the trigger ring 1000, either by active application of pressure from a spring or passive application of pressure from other alternative structures such as a button, the trigger assembly can immediately assume the second unlocked position shown in Figures 15-16. It can be appreciated that in the process of the trigger assembly switching from the first locked position to the second locked position, the transport tube seat 2000 can only have a vertical upward movement, i.e., an upward movement without rotation, to assume the second unlocked position relative to the trigger ring 1000.

[0082] The second unlocked position shown in Fig. 15 can correspond to the initial state of the atomizer, i.e., the state in which the atomizer is not operated. From the initial state, when the transport tube seat 2000 rotates together with the housing 8000 and the rotating part 6000, the transport tube seat 2000 rotates downward relative to the trigger ring 1000 by the action of the helical surface 2600 until the first locking surface 1110 is in close contact with the second locking surface 2110, and reaches the locked position shown in Fig. 9, i.e., the pre-trigger state of the atomizer. In this case, applying a substantially horizontal thrust to the trigger ring 1000 can move the trigger assembly away from the locked position to the first unlocked position shown in Fig. 12, thereby completing one stroke cycle.

[0083] It should be understood that the stroke cycle of the trigger assembly can correspond to a full rotation or partial rotation of the trigger ring 1000 and the transport tube seat 2000, depending on the corresponding number and positioning of the locking protrusions 1100 and locking notches 2100 located on the trigger ring 1000 and the transport tube seat 2000.

[0084] Finally, an atomizer according to one embodiment of the present disclosure will be described with reference to Figures 17 to 19. The atomizer includes the above-mentioned trigger assembly to control or prevent the triggering of the atomizer. Here, a trigger ring 1000 is configured as a switch button of the atomizer, or the trigger ring 1000 is connected to the switch button of the atomizer so that it can move with the switch button being pressed. A transport tube seat 2000 is configured as a housing of the atomizer, or the transport tube seat 2000 is connected to the housing of the atomizer so that it can rotate or spirally move with the rotation of the housing.

[0085] When the atomizer is in the initial state, the trigger assembly is in the unlocked position, but when the atomizer is in the pre-trigger position, the trigger assembly is in the locked position, so that the transport tube seat 2000 can rotate in the unlocked position and the trigger ring 1000 can be pushed and moved in the locked position, for example moved substantially horizontally, so that the atomizer moves from the initial position to the pre-trigger position back to the initial state.

[0086] In addition to the trigger assembly, the atomizer may further include other components, such as a housing 8000, a push switch 3000, a container 4000 for containing the liquid to be atomized, a spring 5000 for applying thrust to the transport tube seat 2000, a rotating part 6000 fitted into the transport tube seat 2000, a suction nozzle 7000 (which can be placed in the user's mouth during use), an ejection assembly 9000 for atomizing and ejecting the atomized liquid, and a dust cover 11000.

[0087] In the configurations shown in Figures 17-19, the atomizer may have the following method of operation, but this is not required.

[0088] First, when the atomizer is in its initial position (at which time the trigger assembly is in, for example, the second unlocked position shown in Figures 15 and 16), the user grasps the housing 8000 and rotates the housing at a certain angle, and the rotating member 6000 moves downward (e.g., spirally) along with the rotation of the housing 8000 together with the transport tube seat 2000 until the trigger assembly moves to the locked position shown in Figures 9 to 11.

[0089] At this time, the atomizer is in the preliminary trigger position, and the first locking surface 1110 is in close contact with the second locking surface 2110, so that the trigger ring 1000 and the delivery tube seat 2000 are mutually blocked, and neither can move any further without an external force. In this locked position, unless the user intentionally applies an external force, the atomizer will not perform atomization or spraying even if it is subjected to an external force such as impact or shaking, or even in an unexpected situation such as slipping down from a high place. Therefore, the atomizer is effectively locked in this state.

[0090] When a user wants to use the atomizer, he / she can apply a radially inward thrust to the push switch 3000. Because the first locking surface 1110 and the second locking surface 2110 are three-dimensionally inclined, the thrust can be controlled within a reasonable range. Otherwise, in order to ensure the locking effect, the user must apply a large operating force when unlocking, which will undoubtedly lead to poor usability and poor user experience. At this time, the trigger ring 1000 moves with the movement of the push switch 3000. It can be understood that the first locking surface 1110 slides in a three-dimensional direction on the second locking surface 2110, and this movement of the trigger ring 1000 with the push switch 3000 can be not only a linear translation, but also a curvilinear translation accompanied by rotation. Such a curvilinear translation allows the trigger assembly to switch relatively smoothly between the locked position and the unlocked position. Preferably, during this sliding, the guide surface 1120 of the trigger ring 1000 also contacts the bottom of the groove of the locking notch 2100 and slides relative to it, and this double contact sliding can reduce the friction between the first locking surface 1110 and the second locking surface 2110, thereby extending the service life of the trigger assembly.

[0091] When the first locking surface 1110 of the trigger ring 1000 moves to a position where it no longer contacts the second locking surface 2110, the atomizer moves from the pre-trigger position to a free position (where the trigger assembly is in the first unlocked position shown in Figures 12-14). In the free position, the atomizer is unlocked and the transport tube seat 2000 is free to move relative to the trigger ring 1000. However, the atomizer is only able to move axially relative to the trigger ring 1000 because the transport tube seat 2000 is constrained in the radial direction by the rotating component 6000 or the housing 8000. Also, because the outer diameter of the transport tube seat 2000 is smaller than that of the trigger ring 1000, the transport tube seat 2000 will passively or actively, for example by spring force or thrust, move vertically upward through the trigger ring 1000 to its highest point, thereby causing the trigger assembly to also return to, for example, the second unlocked position shown in Figures 15-16, i.e., the atomizer will also return to its initial position.

[0092] It should be understood that the internal structure and parts of the atomizer shown in the drawings are exemplary and not limiting. As long as it is possible to realize the function of preventing the atomizer from being erroneously operated or accidentally triggered, the atomizer including the above-mentioned trigger assembly that can realize the function may have any structure or parts, without being limited to the parts and arrangements in the drawings. In addition, the above-mentioned operation method of the atomizer is also exemplary and not limiting. When the parts in the atomizer are omitted or replaced, the operation method can be correspondingly changed to meet the needs of use.

[0093] The above are merely embodiments or examples of the present disclosure, and are not intended to limit the scope of the claims of the present disclosure.
