Description

Actuating assembly and atomizer Technical Field

[0001] The present application relates to the technical field of drug spraying, and in particular to an actuating assembly and an atomizer. Background Art

[0002] A nebulizer is an important drug delivery device. Existing nebulizers, such as the one with publication number CN103272730B, require a holder to move to aspirate liquid during the preparation phase of use. At the end of the preparation phase, in order to smoothly engage the locking element, the holder usually needs to move excessively. This arrangement creates a small gap between the holder and the locking element. After the locking element engages the upper side of the holder, the holder does not stop moving immediately, but instead produces a short return stroke.

[0003] Because the movement of the retaining element is directly linked to the liquid suction and spraying of the spray mechanism, this return stroke significantly causes a small amount of spray from the spray mechanism. In other words, conventional atomizers spray droplets during the initial preparation phase, resulting in wasted liquid and a poor user experience. Furthermore, to facilitate the locking element's smooth engagement with the upper side of the retaining element, there is a gap in the locking element's assembly position. This creates a noticeable noise when the atomizer is shaken, resulting in poor structural stability for conventional atomizers. Summary of the Invention

[0004] In view of this, embodiments of the present application provide an actuator assembly and an atomizer to solve the problem that it is difficult to avoid liquid spraying during the preparation stage of the existing atomizer during use.

[0005] In a first aspect, an embodiment of the present application provides an actuating assembly for driving an atomizer to aspirate liquid and spray, comprising:

[0006] A holding member that moves to enable the atomizer to absorb liquid and spray, wherein when the holding member moves in a first direction, the atomizer absorbs liquid, and when the holding member moves in a second direction, the atomizer sprays, wherein the second direction is opposite to the first direction;

[0008] a matching member for guiding the movement of the holding member;

[0009] When the rotating member rotates, the holding member continuously passes through at least the first stage and the second stage under the guidance of the matching member.

[0010] In the first stage, the holding member rotates and moves along the first direction to allow the atomizer to absorb liquid;

[0011] In the second stage, the relative position of the holding member in the first direction remains unchanged, so as to limit the movement of the holding member along the second direction and prevent the atomizer from leaking liquid.

[0027] When the locking element is disengaged from the slot, the locking element is in the fourth state.

[0028] In conjunction with the second aspect, in an optional embodiment, the atomizer further includes: a first elastic member, the first elastic member abutting against the holding member, and configured to apply a first thrust in the second direction to the holding member;

[0029] The projection of the retaining member along the second direction partially overlaps with the locking element, so that the retaining member can drive the locking element to change from the third state to the fourth state under the action of the first thrust.

[0030] In combination with the second aspect, in an optional embodiment, the atomizer further includes a second elastic member, which abuts the locking element and is used to apply a second thrust along the first direction to the locking element so that the locking element is transformed from the fourth state to the third state under the action of the second thrust, and the second thrust is less than the first thrust.

[0031] In combination with the second aspect, in an optional embodiment, the retaining member overcomes the first thrust and moves in the first direction in the first stage, and the locking element abuts against the end face of the rotating member under the action of the second thrust and slides along the end face to gradually approach the slot.

[0032] In combination with the second aspect, in an optional embodiment, the atomizer further includes a lower shell, which is sleeved outside a portion of the rotating member and is configured to be rotated by a user to drive the rotating member to rotate.

[0033] In combination with the second aspect, in an optional embodiment, the atomizer further includes an unlocking member, and the unlocking member is used to push the matching member to rotate so as to release the holding member from the second state.

[0041] The above technical solution of the present invention has the following advantages over the prior art:

[0042] 1. The actuator assembly and nebulizer provided by the present invention feature a retaining member guided by a mating member. As the rotating member rotates, the retaining member progresses through a first and second phases. After reaching its maximum position in the first direction during the first phase, the retaining member enters the second phase, maintaining its relative position along the first direction. This arrangement prevents the retaining member from returning during the final phase of the nebulizer's aspiration, preventing leakage during the nebulizer's preparation phase, preventing liquid waste, and improving the user experience.

[0043] 2. The retaining member of the actuator assembly provided by the present invention can maintain a relative position along the first direction unchanged throughout the second stage. That is to say, for the atomizer using the actuator assembly of the present invention, the locking position of the locking element can be any position of the retaining member in the second stage. Therefore, the atomizer using the actuator assembly of this embodiment can solve the problem that the locking element is difficult to insert smoothly, and the assembly position of the locking element does not require artificially designed free clearance. Therefore, the atomizer using the actuator assembly of the present invention has a stable structure and will not produce abnormal noise.

[0044] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In order to fully understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.

[0067] This embodiment provides an atomizer, as shown in FIG. 1 to FIG. 6 , including: a rotating member 4 , a holding member 9 , a spraying mechanism 2 and a liquid storage container 8 .

[0068] The use of the atomizer includes a preparation phase and a spray phase. During the preparation phase, the rotating member 4 can drive the holding member 9 to move in a first direction. This movement of the holding member 9 in the first direction allows the spray mechanism 2 to draw liquid from the liquid storage container 8, thus achieving liquid aspiration by the atomizer. After the spray phase is triggered, the holding member 9 moves in a second direction, and the liquid drawn in by the spray mechanism 2 is sprayed out of the atomizer spray end in the form of an aerosol.

[0069] The liquid in the liquid storage container 8 can be an aqueous pharmaceutical preparation, which may contain a suspension or the like. It is understood that the liquid in the medicine tank is not limited thereto.

[0070] Generally, to facilitate transmission, the rotating member 4, retaining member 9, spray mechanism 2, and liquid storage container 8 are coaxially arranged. Therefore, the first and second directions described in this embodiment can be understood as two axial directions. With reference to Figure 1 , the sprayer of this embodiment is positioned vertically with the spray tip at the top. The first direction is downward, and the second direction is upward. The different positions of the retaining member 9 in the first and second directions refer to different heights of the retaining member 9. In some embodiments, including but not limited to the coaxial rotation of the rotating member 4, retaining member 9, spray mechanism 2, and liquid storage container 8, the axes of the components involved in the transmission can also coincide with the overall axis of the atomizer.

[0071] This embodiment provides an actuating assembly for driving an atomizer to absorb liquid and spray, as shown in FIG. 1 to FIG. 6 , comprising: a holding member 9 , a rotating member 4 and a matching member 12 .

[0072] The holder 9 moves to enable the atomizer to aspirate and spray liquid. When the holder 9 moves in a first direction, the atomizer aspirates liquid. When the holder 9 moves in a second direction, the atomizer sprays liquid, wherein the second direction is opposite to the first direction. The rotating member 4 is connected to the holder 9. Rotation of the rotating member 4 can drive the holder 9 to rotate, or drive the holder 9 to rotate and move in the first direction. The mating member 12 is used to guide the movement of the holder 9.

[0073] Among them, when the rotating member 4 rotates, the retaining member 9 continuously passes through at least the first stage and the second stage under the guidance of the matching member 12. In the first stage, the retaining member 9 rotates and moves along the first direction to allow the atomizer to absorb liquid; in the second stage, the retaining member 9 remains in a constant relative position in the first direction to limit the movement of the retaining member 9 along the second direction and prevent the atomizer from leaking liquid. At the same time, because the actuating assembly provided in the embodiment of the present application can maintain a constant relative position along the first direction throughout the second stage, that is, for the atomizer using the actuating assembly of this embodiment, the locking position of its locking element can be any position of the retaining member 9 in the second stage, so the atomizer using the actuating assembly of this embodiment can solve the problem that the locking element is difficult to insert smoothly, and the assembly position of the locking element does not require artificial design of free clearance. Therefore, the atomizer using the actuating assembly of this embodiment has a stable structure and will not produce abnormal noise.

[0074] The actuator assembly provided in the embodiment of the present application has a retaining member 9 which is guided by a fitting member 12. As the rotating member 4 rotates, the retaining member 9 continuously passes through the first stage and the second stage, so that after the retaining member 9 reaches the farthest position in the first direction during the process of driving the nebulizer to absorb liquid in the first stage, it can immediately maintain the relative position along the first direction unchanged in the second stage. With such an arrangement, the retaining member 9 will not have a return stroke phenomenon in the final stage of driving the nebulizer to absorb liquid, thereby avoiding leakage in the nebulizer preparation stage, avoiding waste of liquid medicine, and improving the user experience. In addition, if a locking element is required to lock the retaining member 9 or the rotating member 4, since the retaining member 9 will not have a return stroke phenomenon during the entire second stage, the locking element can be easily locked without causing the retaining member 9 to have a return stroke after the locking is completed.

[0075] When the rotating member 4 rotates in a specific direction (such as clockwise or counterclockwise), the holding member 9 switches between at least the first state and the second state under the guidance of the matching member 12. The first state and the second state are two states in which the holding member 9 has different positions in the first direction. In the preparation stage, the holding member 9 moves along the first direction and switches from the first state to the second state. The switching process continuously passes through the first stage and the second stage, that is, the holding member 9 is in the first state at the starting point of the first stage, and the holding member 9 is in the second state at the end point of the second stage; in the spraying stage, the holding member 9 moves along the second direction and switches from the second state to the first state. Therefore, it can be understood that the spraying stage is the stage in which the holding member 9 resets from the second state to the first state. The switching between the first state and the second state can be repeated multiple times. "Multiple" generally refers to a quantity of at least 2.

[0076] The state of the holder 9 can be switched manually, requiring the user to actively rotate the rotating member 4, or electrically, using a built-in drive element within the atomizer to drive the rotating member 4. The rotation of the rotating member 4 causes the holder 9 to transition from the first state to the second state, guided by the mating member 12. When the holder 9 reaches the second state, the nebulizer's preparation phase ends. The holder 9 can also be reset from the second state to the first state; the specific operation will be described below.

[0077] In an optional embodiment, in order to realize that the rotation of the rotating member 4 can drive the holding member 9 to rotate or drive the holding member 9 to rotate and move along the first direction, the rotating member 4 is connected to the holding member 9 through a first limiting structure. As for the first limiting structure, specifically, as shown in Figures 3 and 4, the first limiting structure in this embodiment includes an axial rib 401 protruding from the inner wall of the rotating member 4 and an axial groove 901 formed on the outer wall of the holding member 9. The rib 401 is inserted into the groove 901. Since the length of the groove 901 is greater than the length of the rib 401, the rib 401 can move along the groove 901. Since the groove 901 and the rib 401 have a clearance fit in width, when the rotating member 4 rotates, the holding member 9 can be driven to rotate together through the rib 401. In other embodiments, the extension direction of the rib 401 is not limited to the axial direction, and can be at a certain angle to the axial direction, depending on the specific design of the product. The first limiting structure may also be a ridge 401 provided on the holding member 9 and a sliding groove 901 provided on the inner wall of the rotating member 4 .

[0078] In an optional embodiment, the mating member 12 is connected to the retaining member 9 via a cam structure, which is used to guide the retaining member 9 through the first and second stages. A cam structure is a structure used to guide an object to move periodically along a specific path, and can be used to guide the movement of the retaining member 9 in the first and second stages.

[0079] Specifically, in this embodiment, as shown in FIG3 , the circumference of the retaining member 9 includes a first slope 902 and a first flat surface 903 connected to the first slope 902. The first slope 902 continuously changes in height along the axial direction of the retaining member 9, while the first flat surface 903 maintains a constant height along the axial direction of the retaining member 9. As shown in FIG5 , the circumference of the mating member 12 includes a second slope 1204 and a second flat surface 1203 connected to the second slope 1204. The second slope 1204 continuously changes in height along the axial direction of the mating member 12, while the second flat surface 1203 maintains a constant height along the axial direction of the mating member 12. As shown in FIG6 , the first slope 902 can mate with the second slope 1204 to form an abutment, and the first flat surface 903 can mate with the second flat surface 1203 to form the abutment.

[0080] The working principle of the above-mentioned second slope 1204 and second plane 1203 is to form a guide surface whose height first changes and then remains unchanged. Specifically, the second slope 1204 is a spirally ascending slope, and the guide surface is also in a spirally ascending shape. When the abutting portion of the retaining member 9 that cooperates with it abuts against the guide surface, when the mating member 12 does not rotate and the retaining member 9 rotates relative to the mating member 12, the retaining member 9 will move along the guide surface while rotating. Therefore, during the transition process of the retaining member 9 from the first state to the second state, the retaining member 9 also moves along the first direction when rotating. After the abutting portion begins to contact the second plane 1203, the retaining member 9 does not change its position along the first direction when rotating.

[0081] In this embodiment, the first slope 902 serves as the abutment site for the second slope 1204, and the first plane 903 serves as the abutment site for the second plane 1203. It is understandable that, because the movement directions of the mating member 12 and the retaining member 9 are relative, the first slope 902 and the first plane 903 can obviously also serve as guide surfaces, and the second slope 1204 and the second plane 1203 can serve as abutment sites, and the abutment sites are not limited to the slope plus plane structure provided in this embodiment. In addition to the second slope 1204 and the second plane 1203, the first slope 902 and the first plane 903 are provided in this embodiment, which can improve the contact fit between the retaining member 9 and the mating member 12 and enhance the smoothness of the transmission between the retaining member 9 and the mating member 12. In other embodiments, only the first slope 902 and the first plane 903 may be provided, and abutment portions may be provided at corresponding positions of the mating piece 12; or the first slope 902 and the first plane 903, the second slope 1204 and the second plane 1203 may be provided at the same time, with the first slope 902 and the second slope 1204 being the abutment portions against each other, and the first plane 903 and the second plane 1203 being the abutment portions against each other.

[0082] The motion pattern of the cam follower depends on the cam's profile or the shape of the groove. The cam can convert continuous rotational motion into reciprocating linear motion, thus achieving complex motion patterns. It is understood that in addition to the cam structure described above in this embodiment, other types of cam structures may be used in other embodiments, and are not limited to the arrangement in which the first slope 902 serves as the abutment portion for the second slope 1204 and the first plane 903 serves as the abutment portion for the second plane 1203.

[0083] This embodiment provides an atomizer including the aforementioned actuating assembly.

[0084] In an optional embodiment, as shown in Figures 7 and 8, the atomizer further comprises a locking element 10, which is used to lock the retaining member 9 in the second stage. The provision of the locking element 10 can lock the retaining member 9 in the second stage of movement, i.e., it can no longer move. Its function is to ensure that the liquid is absorbed into place during the preparation stage of the atomizer, and to avoid the user's excessive operation after the liquid is absorbed into place, which may cause the spray stage to be triggered by mistake. It can also avoid the retaining member 9 from leaking in the return process due to user's misoperation, such as rotating the rotating member 4 in the direction indicated by the product and then reversing the rotating member 4. The locking element is used to lock the retaining member 9 or the rotating member 4. Since the retaining member 9 will not return during the entire second stage, the locking element can be easily locked without causing the retaining member 9 to return after the locking is completed. For the atomizer of this embodiment, when the user needs to start the spray stage, he can unlock the locking element 10 and trigger the spray stage at the same time or later.

[0085] In this embodiment, as shown in Figures 7 and 8, the locking element 10 has a third state and a fourth state. As shown in Figure 8, when the locking element 10 is in the third state, the locking element 10 abuts against the rotating member 4 to restrict the rotation of the rotating member 4. This effectively restricts the user from rotating the lower housing 6 (the lower housing 6 is the component directly grasped by the user and used to drive the rotating member 4), indicating to the user that the liquid has been aspirated and no further rotation is required. It also directly prevents the user from accidentally triggering the spray. When the locking element 10 is in the fourth state, as shown in Figure 7, the locking element 10 is separated from the rotating member 4, removing the rotation restriction on the rotating member 4, allowing the user to rotate the lower housing 6 again for the next use. When the retaining member 9 is in the first state, the locking element 10 is in the fourth state, i.e., the rotating member 4 is unlocked and the user can rotate it. When the retaining member 9 is in the second state, the locking element 10 is in the third state, i.e., the rotating member 4 is locked and the user cannot rotate it. Specifically, the timing when the locking element 10 enters the third state is the second stage of the process in which the retaining member 9 switches from the first state to the second state. Since the retaining member 9 does not displace axially during the entire second stage, there is no requirement for the accuracy of the specific locking position of the locking element 10. This is equivalent to that even if the locking element 10 has a large tolerance in manufacturing, it can well complete the locking of the retaining member 9 and ensure that the atomizer will not spray when the retaining member 9 is in the second state.

[0086] In this embodiment, the specific installation position of the locking element 10 is shown in FIG9 . The inner wall of the upper housing 3 has a retaining groove 304 . The locking element 10 is installed in the retaining groove 304 . As shown in FIG7 , the end surface 400 of the rotating member 4 has a slot 402 for the locking element 10 to engage. As shown in FIG8 , when the locking element 10 is engaged with the slot 402 , the locking element 10 is in the third state. As shown in FIG7 , when the locking element 10 is disengaged from the slot 402 , the locking element 10 is in the fourth state. Regarding the specific structure of the slot 402 , the slot 402 is provided on the end surface 400 of the rotating member 4 and needs to extend in both the axial and radial directions of the rotating member 4 to ensure that the rotating member 4 is unable to rotate relative to the upper housing 3 after the locking element 10 is engaged with the slot 402 . The locking element 10 being engaged with the slot 402 means that part of the locking element 10 is located in the slot 402 and the other part is located in the retaining groove 304 , thereby hindering the relative rotation between the rotating member 4 and the upper housing 3 .

[0087] In this embodiment, as shown in FIG1 , the atomizer further comprises: a first elastic member 7, the first elastic member 7 abutting against the retaining member 9, for applying a first thrust in the second direction to the retaining member 9; the projection of the retaining member 9 along the second direction partially overlaps with the locking element 10, so that the retaining member 9 can drive the locking element 10 from the third state to the fourth state under the action of the first thrust. The function of the first elastic member 7 is to enable the locking element 10 to transition from the third state to the fourth state, while allowing the retaining member 9 to transition from the second state to the first state, and is also the direct driving force for the atomizer to spray. The operating principle of the first elastic member 7 is as follows:

[0088] In an alternative embodiment, as shown in Figure 12, the top of the locking element 10, facing the rotating member 4, has a pushing surface 1001. This pushing surface 1001 coincides with the axial projection of the retaining member 9. During the transition of the locking element 10 from the third state to the fourth state, the retaining member 9, under the first thrust of the first elastic member 7, abuts the end of the retaining member 9 against the pushing surface 1001, driving the locking element 10 away from the rotating member 4. Simultaneously, the retaining member 9 moves in the second direction. After the first and second stages, the change in the position of the retaining member 9 along the first direction is reset, indicating that the locking element 10 is in the process of being reset from the second state to the first state. Simultaneously, the movement of the retaining member 9 in the second direction drives the atomizer to spray. In this embodiment, the atomizer further includes a second elastic member 11, one end of which abuts against a limiting column 305 located on the inner wall of the upper housing 3 as shown in FIG9 , and the other end abuts against the locking element 10, for applying a second thrust along the first direction to the locking element 10 so that the locking element 10 is transformed from the fourth state to the third state under the action of the second thrust, and the second thrust is less than the first thrust (the first elastic member 7 and the second elastic member 11 are usually large springs and small springs, respectively. It can be understood that when the large spring pushes the locking element 10, the elastic force of the small spring is much smaller than that of the large spring and is inevitably compressed by the large spring). In the first stage, the retaining member 9 overcomes the first thrust and moves in the first direction. As shown in FIG7 and FIG8 , the locking element 10 abuts against the end face 400 of the rotating member 4 under the action of the second thrust and slides along the end face 400 to gradually approach the slot 402. The principle by which the locking element 10 can approach and contact the end face 400 is as follows: in the first stage, the first thrust applied to the retaining element 9 is overcome by the user operating the lower housing 6 (indirectly operating the rotating element 4), allowing the locking element 10 to approach the end face 400 under the action of the second thrust. Before entering the second stage, the locking element 10 contacts the end face 400 under the action of the second thrust. After entering the second stage, the retaining element 9 has separated from the locking element 10 and maintains a sufficient distance from the locking element 10 to not affect the insertion of the locking element 10 into the slot 402. In the second stage, the side of the locking element 10 facing the end face 400 contacts the end face 400 and slides along the circumference of the end face 400. Furthermore, when the retaining element 9 is in the second state, the first thrust is overcome by the opposing support force provided by the mating element 12, and the locking element 10 can now also be inserted into the slot 402 under the action of the second thrust.

[0089] In an alternative embodiment, as shown in FIG12 , the slot 402 includes a plurality of equally spaced receptacles 4021. The end of the locking element 10 facing the slot 402 includes a plurality of plugs 1003 that can be inserted into the receptacles 4021. The number of plugs 1003 is equal to the number of receptacles 4021. In other embodiments, the number of plugs 1003 can be less than the number of receptacles 4021. In this alternative embodiment, the locking element 10 can more stably lock the rotating member 4 by plugging the plurality of plugs 1003 into the receptacles 4021. The side of the plugs 1003 facing the end face 400 is a sliding surface 1005. In the second stage, the locking element 10 contacts the end face 400 via the sliding surface 1005 and slides along the circumference of the end face 400.

[0090] In this embodiment, the atomizer further includes an unlocking member 5, as shown in Figure 10. The unlocking member 5 is used to push the mating member 12 to rotate, so that the retaining member 9 is released from the second state. The function of the unlocking member 5 is that when the locking element 10 is in the third state, the rotating member 4 is locked, and the rotation operation of the rotating member 4 is no longer possible. In order to release the retaining member 9 from the second state, a structure independent of the rotating member 4 must be adopted, so the unlocking member 5 can cooperate with the locking element 10 to perform the unlocking operation. It should be noted that even if the atomizer of this embodiment is not provided with a locking element 10, it does not affect the use of the unlocking member 5. As long as the user can clearly know that the retaining member 9 is in the second state, the unlocking member 5 can be used normally to push the mating member 12 to rotate, so that the retaining member 9 is released from the second state. For example, by making a scale line on the upper shell 3 to mark the position, the user can know the relative position of the rotation of the lower shell 6, and the locking element 10 can be omitted.

[0091] In an alternative embodiment, as shown in FIG1 , the unlocking member 5 is movably mounted on the sidewall of the upper housing 3. As shown in FIG10 , a pressing portion 501 protrudes from the unlocking member 5 on the side facing the mating member 12, and a third slope 1205 protrudes from the side of the mating member 12 to abut against the pressing portion 501. In this embodiment, the unlocking member 5 and the mating member 12 have a mutually driving structure, namely, the third slope 1205 and the pressing portion 501. The principle is that the third slope 1205 is an inclined surface relative to the extrusion direction of the pressing portion 501. The thrust on the pressing portion 501 can be decomposed into a direction along the extrusion direction and a direction perpendicular to the extrusion direction. In this embodiment, the direction along the extrusion direction refers to the radial direction of the mating member 12, and the direction perpendicular to the extrusion direction refers to the tangential direction of the circumference of the mating member 12. Therefore, movement of the pressing portion 501 along the extrusion direction can cause the mating member 12 to rotate. Conversely, reverse rotation of the mating member 12 can also cause the pressing portion 501 to move in the reverse direction.

[0092] In an optional embodiment, as shown in FIG5 , the end surface of the mating member 12 facing the upper housing 3 has a rotation range limiting groove 1201. As shown in FIG9 , the inner wall of the upper housing 3 has a protrusion 303 that engages with the rotation range limiting groove 1201. The width of the protrusion 303 is smaller than the width of the rotation range limiting groove 1201. The retaining member 9 further includes a transition state before the first state. When the retaining member 9 is in the transition state, the unlocking member 5 is close to the mating member 12, and the protrusion 303 is located at the first end of the rotation range limiting groove 1201. When the retaining member 9 is in the first state, the unlocking member 5 is located away from the mating member 12, and the protrusion 303 is located at the second end of the rotation range limiting groove 1201, which is opposite the first end.

[0093] Among them, the function of the rotation range limit groove 1201 is to provide space for a part of the rotation of the mating part 12, and at the same time limit the rotation of the mating part 12. When the protrusion 303 rotates along the preset rotation direction until it abuts against the second end of the rotation range limit groove 1201, the mating part 12 will no longer be able to rotate along the preset rotation direction.

[0094] The atomizer of this embodiment, the user's operation in one use cycle includes the following process:

[0095] ① Initial state: the retaining member 9 is in the transition state, the locking element 10 is in the fourth state, and the locking element 10 is at the farthest end facing the slot 402 in the second direction, and the unlocking member 5 is close to the mating member 12.

[0096] ② To begin operation, rotate the lower housing 6 in the predetermined direction, driving the rotating member 4, which in turn drives the first ramp 902 of the retaining member 9, pushing the mating member 12 to rotate. At this point, because the second end of the rotation range limiter 1201 of the mating member 12 has not yet abutted the protrusion 303, the mating member 12 can rotate within a limited range. As the mating member 12 rotates, the corresponding unlocking member 5 begins to move away from the mating member 12 until the retaining member 9 reaches the first state, where the unlocking member 5 is positioned away from the mating member 12 and the locking element 10 is offset in the second direction from the position directly opposite the slot 402.

[0097] ③ Continuing to rotate the lower housing 6, the user overcomes the first thrust and drives the rotating member 4 to rotate, thereby driving the retaining member 9 to enter the first stage. During this process, although the locking element 10 tends to move toward the rotating member 4 under the action of the second thrust of the second elastic member 11, the locking element 10 and the slot 402 are misaligned during this process, so the lower end of the locking element 10 abuts against the end surface 400 of the rotating member 4.

[0098] ④ Continue to rotate the lower housing 6, driving the holding member 9 to enter the second stage until the locking element 10 is aligned with the slot 402 and the locking element 10 enters the third state. At this time, the holding member 9 is in the second state. Since the locking element 10 enters the third state, the rotation of the rotating member 4 is restricted, that is, the rotation of the lower housing 6 is restricted. The user can know that the lower housing 6 can no longer rotate and the aspiration of the nebulizer has been completed, that is, the preparation stage is completed;

[0099] ⑤ Start using the atomizer, i.e. trigger the spray. Press the unlocking member 5 so that the unlocking member 5 gradually approaches and pushes the fitting member 12. When the unlocking member 5 is fully pressed, the unlocking member 5 will return to the position in the initial state. At this time, since the fitting member 12 rotates relative to the retaining member 9 (the rotation direction is opposite to the preset rotation direction), the first plane 903 and the second plane 1203 are disengaged. As shown in FIG5 , one side of the second plane 1203 has a drop surface 1202. The drop surface 1202 and the second plane 1203 have a height difference in the second direction. Therefore, when the first plane 903 and the second plane 1203 are disengaged, the first plane 903 moves toward the drop surface 1202 under the first thrust of the first elastic member 7, and the retaining member 9 returns to the transition state. Therefore, the locking element 10 returns to the fourth state, the atomizer performs a spray, the atomizer returns to the initial state, and a use cycle ends.

[0100] In this embodiment, to ensure that the atomizer completes one cycle of use each time the user rotates the lower housing 6 180 degrees, the various components in this embodiment are arranged in two symmetrical groups about the rotation center. For example, as shown in FIG12 , the end surface of the rotating member 4 has two symmetrical groups of slots 402 about the rotation center. As shown in FIG3 , the retaining member 9 has two symmetrical groups of first slopes 902 and first flat surfaces 903 about the rotation center. The mating member 12 has two symmetrical groups of second slopes 1204, second flat surfaces 1203, and drop surfaces 1202 about the rotation center. With this design, the atomizer will produce two sprays with each rotation of the lower housing 6. In other embodiments, it is understood that the aforementioned multiple components can be arranged in three, four, or more rotationally symmetrical groups about the rotation center, so that the atomizer can produce more sprays with each rotation of the lower housing 6. In other embodiments, the aforementioned multiple components can be arranged in only one group about the rotation center, so that the atomizer can produce one spray with each rotation of the lower housing 6.

[0101] In an optional embodiment, as shown in FIG11 , the sidewall of the upper housing 3 has an opening 30 for inserting the unlocking member 5 , and the edge of the opening 30 has a plurality of guide protrusions 302 . As shown in FIG10 , the unlocking member 5 has guide slots 504 at positions corresponding to the guide protrusions 302 , and the guide protrusions 302 snap into the corresponding guide slots 504 . The guide protrusions 302 and the guide slots 504 cooperate with each other to guide the direction of movement of the unlocking member 5 . Specifically, in this embodiment, the unlocking member 5 is in the shape of a button. When the unlocking member 5 is pressed, the unlocking member 5 moves along the extension direction of the guide slots 504 . The extension direction of the guide slots 504 is preferably set to be perpendicular to the sidewall of the upper housing 3 .

[0102] In an optional embodiment, as shown in Figures 10 and 11, the unlocking member 5 is provided with anti-disengagement hooks 505 on both sides of one end of the interior of the upper housing 3, which extend toward the periphery of the opening 30. The anti-disengagement hooks 505 are used to prevent the unlocking member 5 from being disengaged from the opening 30. Specifically, in this embodiment, the main body contour of the unlocking member 5 is consistent with the opening 30, so that it can move within the opening 30. To prevent the unlocking member 5 from being pushed out of the opening 30 excessively when the user operates the unlocking member 5, the anti-disengagement hooks 505 are provided to limit the range of movement of the unlocking member 5 within the opening 30 toward the outside of the upper housing 3. By expanding toward the periphery of the opening 30, the anti-disengagement hooks 505 hook onto the inner wall of the upper housing 3 when the unlocking member 5 moves toward the outside of the upper housing 3, preventing the unlocking member 5 from being pushed out excessively and falling out.

[0103] Furthermore, as shown in Figures 10 and 11 , a stopper 301 is provided at the edge of the opening 30 within the upper housing 3. The unlocking member 5 has a limiting slot 503 at a position corresponding to the stopper 301. The stopper 301 engages within the limiting slot 503 to limit the distance that the unlocking member 5 can move toward the interior of the upper housing 3. The stopper 301 and the limiting slot 503 cooperate to guide the unlocking member 5 in its movement. Furthermore, the stopper 301 prevents the unlocking member 5 from being pushed too far into the interior of the upper housing 3 from the opening 30 during operation, potentially causing it to fall out.

[0104] The atomizer of this embodiment, as shown in FIG1 , comprises an upper shell 3 and a lower shell 6. The upper shell 3 and the lower shell 6 are capable of relative rotation about an axis. The lower shell 6 is sleeved outside a portion of the rotating member 4 and is configured for rotation by a user to drive the rotating member 4. The upper shell 3 includes, from top to bottom, an injection mechanism 2, a fitting member 12, and a retaining member 9. The injection mechanism 2 directly abuts against the inner wall of the upper shell 3, the fitting member 12 directly abuts against the injection mechanism 2, and the retaining member 9 directly abuts against the fitting member 12. Therefore, the range of motion of the retaining member 9 is only related to the manufacturing tolerances of the second slope 1204 and the second plane 1203 of the fitting member 12, as well as the axial height difference between the second plane 1203 and the first plane 903, and has nothing to do with the connection gaps between the injection mechanism 2, the upper shell 3, the fitting member 12, the retaining member 9, and other components (because there is no gap when the fitting member 12 and the retaining member 9 directly abut).

[0105] In this embodiment, the specific connection relationship between the injection mechanism 2, the inner wall of the upper shell 3, the fitting 12 and the retaining member 9 is as follows: As shown in Figure 9, the top of the inner wall of the upper shell 3 (with the upper end shown in Figure 1 as the top) has an annular support sheet 306, and the ridge 303 is connected to the outer side of the annular support sheet 306. The inner side of the annular support sheet 306 is for the injection mechanism 2 to be embedded and installed, and the outer side of the annular support sheet 306 is for the fitting 12 to be sleeved. The injection mechanism 2 is embedded in the inner side of the annular support sheet 306 and the top end abuts the top of the inner wall of the upper shell 3. As shown in Figure 13, the injection mechanism 2, the fitting 12 and the retaining member 9 are arranged in sequence from top to bottom. The injection mechanism 2 has a first abutting surface 201 facing the lower end, the inner side of the fitting 12 has a second abutting surface 1206 facing the upper end, the outer side of the fitting 12 has a third abutting surface 1207 facing the lower end, and the inner side of the retaining member 9 has a bottom surface 905 facing the upper end. When the ejection mechanism 2 , the fitting member 12 and the retaining member 9 are assembled, the second abutting surface 1206 abuts against the first abutting surface 201 , and the bottom surface 905 abuts against the third abutting surface 1207 .

[0106] Specifically, in this embodiment, the movable range of the retaining member 9 is between two extreme positions. When the retaining member 9 is in the first state, it is also in an extreme position closest to the mating member 12. When the retaining member 9 is in the second state, it is also in another extreme position farthest from the mating member 12. Here, the relative distance between the retaining member 9 and the mating member 12 is measured using the center of mass of the two as a reference. As shown in Figures 3 and 5, the retaining member 9 is sleeved outside the mating member 12; when the retaining member 9 is in the first state, the third abutting surface 1207 of the mating member 12 facing one end of the retaining member 9 abuts against the bottom surface 905 inside the retaining member 9. That is, the abutting position accuracy of the third abutting surface 1207 and the bottom surface 905 determines the accuracy of the first extreme position, while the accuracy of the second extreme position is determined by the axial height difference of the second plane 1203 relative to the third abutting surface 1207. It is not difficult to see that the second plane 1203 and the third abutting surface 1207 are both part of the mating member 12. There are no assembly errors, only manufacturing tolerances. Therefore, the range of motion of the retaining member 9 is relatively precise, which is equivalent to the relatively precise dosage of a single spray of the atomizer of this embodiment. Therefore, the dimensional influence of the atomizer of this embodiment is affected by its processing accuracy, and there is no influence of assembly accuracy. Therefore, the atomizer of this embodiment improves the metering accuracy of the product compared to the atomizer of the prior art, and the components inside the housing are less likely to produce shaking sounds, improving the user experience.

[0107] In an optional embodiment, the third abutting surface 1207 and the second plane 1203 are in the same plane. This design can simultaneously form the third abutting surface 1207 and the second plane 1203 in the process, further reducing the error.

[0108] In an optional embodiment, as shown in FIG9 , the inner wall of the upper housing 3 further comprises two limiting pieces 309 . The limiting pieces 309 and the limiting groove 304 are both used to limit the locking element 10 to ensure that the locking element 10 can and can only move in the axial direction of the atomizer. Specifically, as shown in FIG12 , the locking element 10 has a first limiting surface 1002 and a second limiting surface 1006 on both sides, wherein the first limiting surface 1002 is embedded between the two limiting pieces 309 to be limited, and the second limiting surface 1006 is embedded in the limiting groove 304 to be limited. With this limiting structure, the axial movement of the locking element 10 in the atomizer is more stable.
