nebulizer

Abstract

This invention relates to an atomizer. The atomizer includes a guide member, a spray actuator, and a force-saving structure. The spray actuator is used to resist and drive the guide member to rotate along a first rotation direction under the action of an external force, thereby triggering the atomizer to spray. When the external force acts on the spray actuator, the force-saving structure can decompose the external force into an actuating component, which is greater than the external force. The actuating component is used to drive the guide member to rotate along the first rotation direction. By setting the actuating component to drive the guide member to rotate along the first rotation direction, the external force required to trigger the spray is reduced, making the atomizer spray triggering more effortless and the operation easier and smoother.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a nebulizer. Background Technology

[0002] A nebulizer is an important drug delivery device. Existing nebulizers, such as the one disclosed in CN121177621A, incorporate an obstruction structure that generates a component force on the guide member. This component force prevents the guide member from rotating in a first rotational direction. When it is necessary to release the restriction of the limiting part on the confined part, the external force must overcome the triggering force and component force of the spray actuator to disengage the limiting part from the confined part, thereby triggering the spray. This increases the difficulty of triggering the spray actuator, avoids accidental triggering caused by non-button-related factors such as shaking, dropping, or impact, and improves the stability of the nebulizer during use.

[0003] However, to achieve the effect of preventing accidental triggering, the above settings need to overcome two resistances simultaneously during the triggering process, resulting in the user actually applying a significantly higher triggering force, making the user operation laborious and the user experience poor. Summary of the Invention

[0004] Therefore, it is necessary to provide a new type of atomizer that addresses the problem of users applying excessive triggering force when using current atomizers designed to prevent accidental triggering, resulting in cumbersome operation and a poor user experience.

[0005] An atomizer, the atomizer comprising: Guide component; A spray actuator is used to abut against and drive the guide to rotate in a first rotation direction under the action of an external force, so as to trigger the atomizer to spray; The force-saving structure decomposes the external force into an actuating component when an external force is applied to the spray actuator. The actuating component is greater than the external force and is used to drive the guide to rotate along the first rotation direction.

[0006] In one embodiment, the force-saving structure includes a force-applying part, an actuating part, and a receiving part. The force-applying part and the actuating part are respectively disposed on opposite sides of the spray actuator, and the receiving part is disposed on the guide. The force-applying part allows the user to apply external force. When the actuating part abuts against the receiving part under the action of external force, the position where the actuating part and the receiving part abut against each other is the docking point, and the external force is decomposed into a first component force acting on the docking point. In the radial cross section where the spray actuator, the force-saving structure, and the guide cooperate, a first angle is formed between the line of force application and the normal at the docking point, and a second angle is formed between the first tangent at the docking point and the normal at the docking point, and the sum of the first angle and twice the second angle is less than 90°, so that the actuating component force is greater than the external force.

[0007] In one embodiment, the first included angle ranges from 0° to 45°.

[0008] In one embodiment, the first included angle is 10°.

[0009] In one embodiment, the guide includes a guide ring and a receiving protrusion disposed on the outside of the guide ring, the receiving protrusion having a receiving mating surface, the receiving mating surface constituting the receiving portion;

[0010] The spray actuator is provided with an actuating protrusion that mates with the receiving mating surface, and the actuating protrusion constitutes the actuating part.

[0011] In one embodiment, the receiving mating surface is concave or inclined.

[0012] In one embodiment, the actuating protrusion has a sloping driving surface facing the receiving mating surface, and the sloping driving surface constitutes the actuating part; When an external force is applied to the spray actuator, the inclined push driving surface and the receiving mating surface come into contact.

[0013] In one embodiment, the inclined push driving surface is provided with an inclined push tip facing the receiving mating surface, and the inclined push tip constitutes the actuating part; When an external force is applied to the spray actuator, the angled push tip makes point-to-surface contact with the receiving mating surface.

[0014] In one embodiment, the inclined push driving surface is provided with an inclined push protrusion facing the receiving mating surface, and the inclined push protrusion constitutes the actuating part; When an external force is applied to the spray actuator, the oblique push protrusion and the receiving mating surface are in line-to-surface contact.

[0015] In one embodiment, there are multiple receiving mating surfaces, and the multiple receiving mating surfaces are connected in sequence; When an external force is applied to the spray actuator, causing the actuator to drive the guide to rotate along the first rotation direction, the plurality of the receiving mating surfaces sequentially abut against the actuator along the first rotation direction; When no external force is applied, among the plurality of receiving and mating surfaces, the receiving and mating surface facing the actuating part is the first mating surface, the second included angle α formed by the first mating surface and the actuating part at the docking point is α1, and the first included angle β formed by the first mating surface and the actuating part at the docking point is β1.

[0016] In one embodiment, the receiving mating surface adjacent to the first mating surface is the second mating surface, and the second included angle α formed by the second mating surface and the actuating part at the docking point is α2, where α2≥α1.

[0017] The aforementioned atomizer, by incorporating a spray actuator, triggers the atomizer to spray by engaging and driving a guide member to rotate in a first rotation direction under external force. Simultaneously, a force-saving structure decomposes the external force into an actuating component greater than the external force. This actuating component can drive the guide member to rotate in the first rotation direction, thereby reducing the external force required to trigger the spray and making the atomizer's spray triggering more effortless and operation easier and smoother.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0042] The terms "first direction a", "second direction b", "first rotation direction c", and "second rotation direction d" mentioned in this invention are based on the markings in the figures.

[0043] like Figure 1 , Figure 2 As shown, one embodiment of this application provides an atomizer 10, which includes a spray actuator 100, a guide 200, a retainer 300, an elastic member 400, a spray assembly 500, and a container 600.

[0044] The spray actuator 100 is used to abut against and drive the guide 200 to rotate in the first rotation direction c under the action of an external force, so as to trigger the atomizer 10 to spray. Specifically, the guide 200 is used to guide the movement of the retainer 300, and the movement of the retainer 300 is used to trigger the atomizer 10 to spray or draw liquid.

[0045] To facilitate the movement of the retainer 300 to trigger the atomizer 10 to spray or draw liquid, the spray assembly 500 is specifically configured to include a delivery component 510, a nozzle 520, a pressure chamber 530, and a pump body 540. The nozzle 520 is located at the outlet end of the pump body 540, and the pressure chamber 530 is located inside the outlet end of the pump body 540. One end of the delivery component 510 is inserted into the pump body 540, and the other end passes through the retainer 300 and is inserted into the container 600. The delivery component 510 is used to draw liquid from the container 600 and deliver it to the pressure chamber 530 for temporary storage. The nozzle 520 is used to spray the liquid stored in the pressure chamber 530 in a mist form. With the above configuration, the delivery component 510 is mounted on the retainer 300, and the retainer 300 is used to drive the movement of the delivery component 510.

[0046] Specifically, when the retainer 300 rotates along the second rotation direction d, the retainer 300 also moves along the first direction a under the guidance of the guide 200. At this time, the retainer 300 compresses the elastic member 400 and is constrained by the guide 200. The elastic member 400 stores elastic potential energy. When the retainer 300 moves along the first direction a, the retainer 300 drives the infusion member 510 to move along the first direction a. The infusion member 510 draws liquid from the container 600 and delivers it to the pressure chamber 530 for storage. That is, the nebulizer 10 is triggered to be in the liquid absorption stage.

[0047] When the spray actuator 100 drives the guide 200 to rotate in the first rotation direction c, the guide 200 releases the restriction on the retainer 300. Under the rebound force of the elastic member 400, the retainer 300 is displaced in the second direction b. When the retainer 300 is displaced in the second direction b, the retainer 300 drives the infusion member 510 to be displaced in the second direction b. The infusion member 510 squeezes the pressure chamber 530, so that the liquid in the pressure chamber 530 is sprayed out through the nozzle 520. That is, the atomizer 10 is triggered to be in the spraying stage, and the first direction a is opposite to the second direction b.

[0048] It should also be noted that the elastic element 400 is a spring, and the retaining element 300 and the elastic element 400 are distributed sequentially along the first direction a, with one end of the elastic element 400 abutting against the retaining element 300 along the second direction b. When the atomizer 10 is in the atomization stage, under the rebound force of the elastic element 400, the portion of the retaining element 300 that is constrained by the guide element 200 can generate a rotational component force on the guide element 200 that hinders the rotation of the guide element 200 along the first rotational direction c. This rotational component force originates from the elastic element 400.

[0049] With the above settings, the rotational force hinders the guide 200 from rotating along the first rotational direction c, increasing the difficulty of triggering the spray actuator 100, avoiding accidental triggering of the spray due to accidental contact with the spray actuator 100, and improving the stability of the atomizer 10 in use. At the same time, it also results in the user applying a significantly higher triggering force, making the user operation difficult and the user experience poor.

[0050] Based on this, in order to improve the user's operating experience by reducing the user's triggering force while retaining the design for false triggering, an embodiment of the atomizer 10 provided in this application also includes a force-saving structure. When an external force is applied to the spray actuator 100, the force-saving structure can decompose the external force into an actuating component force. The actuating component force is greater than the external force and is used to drive the guide member 200 to rotate along the first rotation direction c.

[0051] With the above settings, the actuating force is greater than the external force, and the actuating force acts on the guide 200 to drive the guide 200 to rotate along the first rotation direction c. This reduces the actual force required for the user to trigger the spray actuator 100, solves the problem of difficult operation for the user in the original design, and significantly improves the user's ease of operation and user experience.

[0052] In addition, by adjusting the docking angle of the spray actuator 100, the force-saving structure and the guide 200, the magnitude of the actuating component of the external force can be adjusted so that the external force applied to the spray actuator 100 is more decomposed into the actuating component to drive the guide 200 to rotate in the first direction a. This helps to reduce the triggering external force applied by the user during operation and further improves the user experience.

[0053] See again Figure 1 The atomizer 10 also includes a mounting housing 700, which has an inner cavity 710. The guide 200 is rotatably mounted in the inner cavity 710 of the mounting housing 700 along its own axis, so that the guide 200 can rotate in the first rotation direction c under the drive of the spray actuator 100. It should be noted that the rotatable mounting of the guide 200 in the mounting housing 700 along its own axis is a disclosed technology and will not be elaborated on here.

[0054] Combination Figure 3 and Figure 4 As shown, the mounting housing 700 is also provided with a mounting frame 720 communicating with the inner cavity 710, and the spray actuator 100 is movably mounted in the mounting frame 720. Specifically, the inner cavity 710 of the mounting housing 700 is provided with positioning ribs 730 spaced apart from the guide 200, and the positioning ribs 730 are positioned opposite to the mounting frame 720.

[0055] When the spray actuator 100 is used to abut against and drive the guide 200 to rotate in the first rotation direction c under the action of external force, the spray actuator 100 also abuts against the side wall of the positioning rib 730 under the action of external force.

[0056] Combination Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the force-saving structure includes a first force-reducing part and a second force-reducing part. The first force-reducing part is configured at the junction of the spray actuator 100 and the guide 200, and includes an actuating part disposed on the spray actuator 100 and a receiving part disposed on the guide 200. The second force-reducing part includes an abutting part connected to the actuating part and a force-applying part disposed on the side of the spray actuator 100 opposite to the actuating part.

[0057] That is, the force-saving structure includes a force-applying part, an actuating part, and a receiving part. The force-applying part and the actuating part are respectively arranged on opposite sides of the spray actuator 100, and the receiving part is arranged on the guide 200. In a specific arrangement, the force-saving structure also includes an abutting part, which is connected to the actuating part.

[0058] When the user applies force through the force-applying part, the actuating part abuts against the receiving part under the action of the external force, and the abutting part abuts against the side wall of the positioning rib 730 under the action of the external force. The position where the actuating part abuts against the receiving part is the docking point M, and the position where the abutting part abuts against the positioning rib 730 is the abutting point K.

[0059] With the above settings, when the user applies an external force F through the force application part, the external force F can be decomposed into a first component force F2 acting on the docking point M, and a second component force F1 acting on the abutment point K. It should be noted that the first component force F2 and the second component force F1 can act on the corresponding docking point M and abutment point K through parallel movement.

[0060] In the radial section where the spray actuator 100, the force-saving structure, and the guide 200 cooperate, specifically in the radial section of the spray actuator 100, the force-saving structure, the guide 200, and the mounting housing 700, a first included angle β is formed between the line of force application N1 and the normal L2 of the docking point M, and a second included angle α is formed between the first tangent L1 of the docking point M and the normal L2 of the docking point M.

[0061] Among them, the line of action of the force N1 is a straight line through the force-applying part that applies the force; an auxiliary circle e is formed with the axis of the guide 200 as the center and the distance from the docking point to the center as the radius. The normal line L2 is perpendicular to the second tangent line of the docking point M at the auxiliary circle e, and the normal line L2 points to the center of the auxiliary circle e; the first tangent line L1 is perpendicular to the direction of the first component force F2 on the docking point M.

[0062] According to the parallelogram law of forces, F2 = F / sin(α+β). F2 can act on the mating point M through translation. When F2 acts on the mating point M, it should also be noted that the F2 acting on the mating point M can be decomposed into a radial component f2 along the normal L2 direction and an actuating component f1 perpendicular to the normal L2 direction. The direction of the actuating component f1 is also the tangent direction of the mating point M at the auxiliary circle e towards the first rotation direction c. Therefore, the actuating component f1 can drive the guide 200 to rotate along the first rotation direction c.

[0063] Based on this, according to the parallelogram law of forces, we have: f1 = F2 * cos(α), or f1 = F * cos(α) / sin(α + β). Since the actuating force f1 is greater than 0, 0° < α < 90°, -α < β < 90°. Calculations show that when 2α + β < 90°, that is, the sum of the first included angle β and twice the second included angle α is less than 90°, the actuating force f1 is greater than the external force F. Under the condition that 2α + β < 90°, when the value of β is fixed, according to f1 = F * cos(α) / sin(α + β), f1(α) strictly decreases monotonically. To make the actuating force f1 as greater than the external force F as possible, both α and β should be as small as possible.

[0064] Preferably, the value of β is in the range of 0°≤β≤45°. For example, β can specifically take any value from 5°, 10°, 12°, 15°, 17°, 20°, 23°, 25°, 27°, 28°, 30°, 32°, 34°, 35°, 37°, 38°, 40°, 41°, 42°, 43°, 44° and greater than or equal to 0° and less than 45°.

[0065] It should also be noted that, according to 2α+β<90°, the range of values ​​for α varies with β.

[0066] For example: when β is 45 degrees, the range of α is 0 ≤ α < 22.5°. For example, the specific value of α can be any value among 3°, 5°, 7°, 9°, 10°, 12°, 14°, 16°, 18°, 20°, 21°, 21.5°, 22° and greater than or equal to 0° and less than 22.5°.

[0067] When β is 0°, the line of action of the applied force N1 and the normal L2 are the same straight line. The value range of α is 0 ≤ α < 45°. Specifically, α can take any value among 5°, 10°, 12°, 15°, 17°, 20°, 23°, 25°, 27°, 28°, 30°, 32°, 34°, 35°, 37°, 38°, 40°, 41°, 42°, 43°, 44° and greater than or equal to 0° and less than 45°. More preferably, the value range of α is 20° ≤ α ≤ 40°, because when the value of α approaches 0°, f1 is much greater than F, and the stroke of the driving guide 200 is close to infinite, which does not meet the actual requirements.

[0068] More preferably, when β is 10°, the range of α is 0 ≤ α < 40°. Specifically, α can take any value from 3°, 4°, 8°, 10°, 11°, 12°, 13°, 15°, 16°, 18°, 20°, 21°, 23°, 25°, 27°, 30°, 32°, 33°, 34°, 35°, 37°, 37° and greater than or equal to 0° and less than 40°. Further, the range of α is 15° ≤ α ≤ 35°.

[0069] The atomizer 10 described above, by setting 2α+β<90°, makes the actuating force f1 greater than the external force F, and by setting 0°≤β≤45°, makes the value of the actuating force f1 greater than the external force F. This can be regarded as the amplification effect of the actuating force f1 on the external force F being greater, so that the user can trigger the atomizer 10 to spray with less force.

[0070] It is easy to understand that angles α and β together determine the magnitude of the actuating force f1, which is also the magnitude of the force that actually drives the guide 200 to rotate.

[0071] See Figure 10 , Figure 11 and Figure 12 In order to facilitate the first force-reducing part being installed at the docking point between the spray actuator 100 and the guide 200, specifically, the guide 200 includes a guide ring 210 and a receiving protrusion 220 disposed on the outside of the guide ring 210. The receiving protrusion 220 has a receiving mating surface 221, and the receiving mating surface 221 constitutes the receiving part in the force-saving structure.

[0072] The spray actuator 100 is provided with an actuating protrusion 110 that mates with the receiving mating surface 221. The actuating protrusion 110 constitutes the actuating part in the force-saving structure. A button protrusion 130 is also provided on the side of the spray actuator 100 opposite to the actuating protrusion 110. The button protrusion 130 constitutes the force-applying part in the force-saving structure. The relative position between the actuating part and the force-applying part is determined by the angle β.

[0073] In specific configurations, the receiving mating surface 221 may be concave or inclined. More specifically, the receiving mating surface 221 may also be a concave arc surface.

[0074] Combination Figure 13 and Figure 14 As shown, the actuating part and the receiving part can be in surface-to-surface contact. Specifically, the actuating protrusion 110 has an inclined push-drive surface 111 facing the receiving mating surface 221, and the inclined push-drive surface 111 constitutes the actuating part. When an external force F is applied to the force-applying part, the inclined push-drive surface 111 and the receiving mating surface 221 come into contact. At this time, both the inclined push-drive surface 111 and the receiving mating surface 221 are preferably inclined surfaces.

[0075] It should also be emphasized that when the actuating part and the receiving part are in surface contact, in the top view of the spray actuator 100, the force-saving structure, and the guide 200, the mating point M between the actuating part and the receiving part is linear. At this time, the mating point M is a butt joint line. The first tangent L1 at any mating point on the mating line forms a second included angle α with the normal L2 of the mating point. The first tangent L1 is perpendicular to the direction of the external force F2 acting on the mating point, and the normal L2 is perpendicular to the second tangent at the mating point on the auxiliary circle e. The normal L2 points to the center of the auxiliary circle e, which is a circle with the axis of the guide 200 as its center and the distance from the mating point to the center as its radius. Figure 14 The diagram illustrates the connection point using the center point of the connection line as the docking point.

[0076] By arranging the actuator and the receiving part in surface-to-surface contact, the contact area between the actuator and the receiving part can be increased, contact stress can be reduced, local wear can be avoided, and power transmission can be made smoother, further improving the smoothness of triggering operation.

[0077] It should also be noted that the actuating protrusion 110 has a positioning surface 113 that is disposed opposite to the inclined push driving surface 111. The positioning surface 113 forms an abutment part and is used to abut against the side wall of the positioning rib 730.

[0078] In a specific configuration, the spray actuator 100 also has a positioning slot 120 that engages with the positioning rib 730, and the positioning surface 113 is also a side groove surface in the positioning slot 120 that abuts against the side wall of the positioning rib 730. With this configuration, when the user applies force to the spray actuator to drive its movement, the positioning rib 730 engages with the positioning slot 120, and the positioning surface 113 abuts against the side wall of the positioning rib 730, thus precisely limiting the direction of movement of the spray actuator.

[0079] In addition, the positioning rib 730 and the positioning slot 120 work together to guide the direction of the spray actuator 100 during its movement. On the other hand, the positioning rib 730 prevents the spray actuator 100 from being pressed too far into the upper mounting shell 700 by the user when operating it, thus preventing it from falling off.

[0080] Combination Figure 15 and Figure 16As shown, the actuating part and the receiving part can have point-to-surface contact. Specifically, the inclined push driving surface 111 is provided with an inclined push tip 112 facing the receiving mating surface 221, and the inclined push tip 112 constitutes the actuating part. When an external force F is applied to the force-applying part, the inclined push tip 112 and the receiving mating surface 221 make point-to-surface contact. In specific settings, the shape of the inclined push tip 112 can be designed as a cone, a pyramid, etc., which can achieve point-to-surface contact while avoiding the tip being too sharp and damaging the receiving mating surface 221, thus ensuring the service life of the atomizer 10. At this time, the receiving mating surface 221 is an inclined surface or a concave surface.

[0081] When the actuating part and the receiving part are in point-to-surface contact, in the radial cross-section of the spray actuator 100, the force-saving structure, the guide 200, and the mounting housing 700, the mating point M between the actuating part and the receiving part is the mating point, and a second included angle α is formed between the first tangent L1 of the mating point and the normal L2 of the mating point. This can be combined with... Figures 5 to 9 To understand.

[0082] The actuating part and the receiving part can also be in line-to-surface contact. Specifically, the inclined push driving surface 111 is provided with an inclined push protrusion facing the receiving mating surface 221, and the inclined push protrusion constitutes the actuating part. When an external force F is applied to the force-applying part, the inclined push protrusion and the receiving mating surface 221 are in line-to-surface contact.

[0083] When the actuating part and the receiving part are in line-surface contact, in the radial cross-section of the spray actuator 100, the force-saving structure, the guide 200, and the mounting housing 700, the mating point M between the actuating part and the receiving part is the mating point, and a second included angle α is formed between the first tangent L1 of the mating point and the normal L2 of the mating point. This can be combined with... Figures 5 to 9 To understand.

[0084] In specific settings, the oblique push protrusion can extend along the length of the oblique push driving surface 111, and its cross-sectional shape can be designed as a triangle, a semi-circle, etc., to ensure a stable line-to-surface contact with the receiving mating surface 221.

[0085] See again Figures 5 to 9 , Figure 13 and Figure 14 As shown, in one embodiment of this application, there are multiple receiving mating surfaces 221, which are connected in sequence. In specific configuration, the number of multiple receiving mating surfaces 221 can be 2, 3 or more.

[0086] When an external force F is applied to the force-applying part, causing the actuator to drive the guide 200 to rotate in the first rotation direction c, multiple receiving mating surfaces 221 sequentially abut against the actuator in the first rotation direction c.

[0087] When no external force F is applied, among the multiple receiving and mating surfaces 221, the receiving and mating surface 221 facing the actuating part is the first mating surface 221a. The second included angle α formed between the first mating surface 221a and the actuating part at the docking point M is α1, and the first included angle β formed between the first mating surface 221a and the actuating part at the docking point M is β1, and 2α1+β1<90° is satisfied. It should be noted that the setting and value of α1 and β1 are consistent with α and β in the previous text.

[0088] It should be noted that when the user applies an external force F to the spray actuator 100, causing the actuator to drive the first mating surface 221a to rotate the guide 200 along the first rotation direction c, the starting effect is achieved. Subsequently, under the support of inertial force, other mating surfaces 221 will pass through the actuator in sequence along the first rotation direction c. The rotation process of the mating surfaces 221 along the first direction a drives the guide 200 to rotate synchronously, so as to release the guide 200 from the restriction of the retaining member 300.

[0089] Therefore, the core objective of this application is to optimize the resistance in the initial triggering stage. By setting the second included angle α formed by the first mating surface 221a and the actuating part at the docking point M as α1, and the first included angle β formed by the first mating surface 221a and the actuating part at the docking point M as β1, and satisfying 2α1+β1<90°, when the user first presses the spray actuating part 100, a small external force F is applied, and sufficient actuating force f1 can be decomposed through the cooperation of the first mating surface 221a and the actuating part, which drives the guide part 200 to start rotating, achieving the effect of "easy start" and solving the problem of excessive initial triggering resistance in the prior art.

[0090] As can be seen from the above, once the initial resistance is overcome and the guide 200 starts to rotate in the first rotation direction c, there is no need to apply too much external force F. Based on this, in order to reduce the stroke of the guide 200 rotating in the first rotation direction c, the guide 200 can release the restriction on the retaining member 300.

[0091] In one embodiment, the receiving mating surface 221 adjacent to the first mating surface 221a is the second mating surface 221b, the second included angle α formed between the second mating surface 221b and the actuating part at the docking point M is α2, and the first included angle β formed between the second mating surface 221b and the actuating part at the docking point M is β2.

[0092] In this case, α2 is not limited to the condition 2α2+β2<90°; α2 can be any value greater than α1.

[0093] With the above settings, when the guide 200 rotates to the point where the second mating surface 221b contacts the drive unit, the actuation component f1 is slightly reduced. At this time, with the support of the inertial force, there is no need to add an external force F, and the guide 200 continues to rotate. This allows the user to easily complete the subsequent triggering operation, while also limiting the rotation stroke of the guide 200 to avoid excessive stroke leading to long operation time, thus further optimizing the user experience.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
