Description

Technical Field

[0001] This utility model relates to the field of aerosol actuator technology, and in particular to a dual-drip aerosol actuator. Background Technology

[0002] Because dual-dip aerosol actuators can be fitted with two different types of aerosols, users can switch between the two spray effects at will according to their needs. This has been recognized and loved by a wide range of users. However, the dual-dip aerosol actuators currently on the market have been unable to be mass-produced due to their complex structural design, numerous parts, and difficult assembly.

[0003] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dual-atom aerosol actuator that is simple in structure, easy to assemble, and low in cost.

[0005] This utility model is achieved through the following technical solution:

[0006] To solve the above-mentioned technical problems, this utility model provides a dual-aperture aerosol actuator, including an upper cover and a lower cover rotatably connected together. The lower cover has a sleeve at its center, and the lower end of the sleeve can be connected to an aerosol valve. The side wall of the sleeve is circumferentially provided with a first channel opening and a second channel opening communicating with its inner cavity. A first nozzle extending radially is provided at the first channel opening, and a second nozzle extending radially is provided at the second channel opening. The outer ends of the first nozzle and the second nozzle are both provided with nozzles. A pressing plate that can move up and down is integrally connected to the center of the upper cover. A pressing locking structure is provided between the pressing plate and the lower cover for locking or unlocking the pressing action of the pressing plate as the central tube rotates. A central tube is provided on the bottom surface of the pressing plate. The central tube is inserted into the sleeve and can rotate therein. A rotation sealing structure is provided between the central tube and the sleeve.

[0007] The rotary sealing structure includes a U-shaped notch on the lower sidewall of the central tube. The outer sidewall of the central tube is in close contact with the inner sidewall of the sleeve. When the notch aligns with the first channel opening as the central tube rotates, the inner cavity of the sleeve connects to the first nozzle to form a first mist spray channel. When the notch aligns with the second channel opening as the central tube rotates, the inner cavity of the sleeve connects to the second nozzle to form a second mist spray channel. When the notch simultaneously shifts away from the first and second channel openings as the central tube rotates, the sleeve is closed, and the pressing action of the pressing plate is locked.

[0008] To further address the technical problems to be solved by this utility model, this utility model provides a dual-atom aerosol actuator in which the upper cover, pressing plate, and central tube are integrally formed, and the lower cover, sleeve, first nozzle, and second nozzle are integrally formed.

[0009] To further address the technical problems to be solved by this utility model, this utility model provides a dual-atom aerosol actuator in which the lower cover is annular, the sleeve is suspended at the center of the lower cover, and the sleeve is connected to the lower cover only through the first nozzle and the second nozzle.

[0010] To further address the technical problems addressed by this invention, a dual-aperture aerosol actuator is provided. The pressing and locking structure includes a support plate extending inward from the periphery of the lower cover. A limiting seat is located at the upper end of the support plate, and the limiting seat has a circumferentially oriented limiting groove. A downwardly extending limiting post is located on the bottom surface of the free end of the pressing plate. When the sleeve is closed, the limiting post moves into the limiting groove and is restricted from moving downward, thus locking the pressing action of the pressing plate. When the inner cavity of the sleeve connects to the first or second nozzle, the limiting post is offset from the limiting seat and located within the ring of the lower cover, thereby unlocking the pressing action of the pressing plate.

[0011] To further address the technical problems to be solved by this utility model, this utility model provides a dual-aperture aerosol actuator in which the support plate is vertically arranged and the limiting seat is arranged circumferentially to form a T-shaped structure.

[0012] To further address the technical problems to be solved by this utility model, the present utility model provides a dual-atom aerosol actuator in which the rotary sealing structure further includes a sealing convex ring and a sealing concave ring that cooperate with each other to form a seal. One of the sealing convex ring and the sealing concave ring is located on the inner side wall of the sleeve, and the other is located on the outer side wall of the central tube.

[0013] In order to further solve the technical problem to be solved by this utility model, in the dual-atom aerosol actuator provided by this utility model, a retaining ring is provided in the middle of the inner cavity of the sleeve, and a sealing ring is provided between the lower end of the central tube and the retaining ring.

[0014] In order to further solve the technical problem to be solved by this utility model, in the dual-atom aerosol actuator provided by this utility model, the part of the inner cavity of the sleeve above the retaining ring and the outer surface of the central tube are both tapered in shape with a smaller bottom and a larger top.

[0015] To further address the technical problem to be solved by this utility model, a dual-aperture aerosol actuator is provided in which a rotation limiting structure is provided between the upper cover and the lower cover to limit the rotation range of the upper cover; the rotation limiting structure includes a left limiting protrusion and a right limiting protrusion disposed around the lower cover, and a limiting head disposed around the upper cover, and the limiting head moves between the left limiting protrusion and the right limiting protrusion as the upper cover rotates, so as to limit the rotation range of the upper cover.

[0016] To further address the technical problems addressed by this invention, a dual-atom aerosol actuator is provided. The upper cover has a nozzle on its side wall, and a side plate is provided around its periphery. Both the first and second nozzles are connected to the side plate. A locking indicator is located between the first and second nozzles on the outer surface of the side plate. When the notch aligns with and connects to the first channel opening, the first nozzle is aligned with the nozzle for first atomization. When the notch aligns with and connects to the second channel opening, the second nozzle is aligned with the nozzle for second atomization. When the sleeve is closed, the locking indicator is aligned with the nozzle, indicating that the pressing action has been locked.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The structural design of this utility model is simple.

[0025] Figure 5 This is a reference diagram showing the usage state of this utility model. Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 5 As shown, this embodiment provides a dual-dip aerosol actuator, which has a simple structure, is easy to assemble, and has a low cost, effectively solving the problems of complex structure and difficult assembly of dual-dip aerosol actuators in the prior art.

[0028] The actuator mainly consists of an upper cover 1 and a lower cover 2, which are rotatably connected, allowing the upper cover 1 to rotate relative to the lower cover 2. In this embodiment, as shown... Figure 2 As shown, the lower cover 2 has several circumferential grooves 29 on its side wall, and the upper cover 1 has several elastic hooks 16. The hooks 16 cooperate with the corresponding grooves 29 to achieve a rotatable connection.

[0029] A sleeve 21 is provided at the center of the lower cover 2. The lower end of the sleeve 21 is designed to connect with an aerosol valve (such as...). Figures 4-5 The structure shown provides a reliable connection for connecting the actuator to the aerosol can. On the side wall of the sleeve 21, a first channel opening 211 and a second channel opening 212 are provided at circumferential intervals, both communicating with the inner cavity of the sleeve 21. A first nozzle 22 extending radially is connected to the first channel opening 211, and a second nozzle 23 extending radially is connected to the second channel opening 212. Nozzles 3 are provided at the outer ends of both the first nozzle 22 and the second nozzle 23, for spraying the aerosol. Specifically, different types of nozzles 3, such as square, round, or fan-shaped, can be used on the two nozzles to achieve different droplet shapes and spray ranges, according to the user's specific requirements for the spray effect.

[0030] A movable pressing plate 11 is integrally connected to the center of the upper cover 1. The pressing plate 11 is used to control the opening of the aerosol valve. Preferably, the pressing plate 11 is connected to the upper cover 1 only through a flexible connecting part at its front.

[0031] A press-locking structure is provided between the press plate 11 and the lower cover 2. This structure can lock or unlock the press plate 11 by rotating the central tube 12, thereby preventing accidental spraying.

[0032] A central tube 12 is provided on the bottom surface of the pressing plate 11. The central tube 12 is inserted into the sleeve 21 and can rotate within the sleeve 21. To ensure the sealing of the aerosol during the spraying process, a rotary sealing structure is provided between the central tube 12 and the sleeve 21.

[0033] The key component of the rotary sealing structure is the U-shaped notch 121 on the lower side wall of the central tube 12. The outer side wall of the central tube 12 is in close contact with the inner side wall of the sleeve 21. When the upper cover 1 is rotated, the central tube 12 is rotated, causing the notch 121 to align with the first channel opening 211. At this time, the inner cavity of the sleeve 21 connects with the first nozzle 22, thus forming a first mist spray channel. At this time, pressing the press plate 11 will cause the aerosol to be sprayed from the nozzle 3 of the first nozzle 22, forming the first mist effect. Similarly, when the notch 121 aligns with the second channel opening 212 as the central tube 12 rotates, the inner cavity of the sleeve 21 connects with the second nozzle 23, forming a second mist spray channel, thus achieving the second mist effect. When the central tube 12 is rotated so that the notch 121 is simultaneously offset from the first channel opening 211 and the second channel opening 212, the sleeve 21 is closed, and the aerosol cannot be sprayed out. At the same time, the pressing locking structure will lock the pressing action of the pressing plate 11 to prevent accidental operation.

[0034] It is worth noting that the design of the U-shaped notch 121 allows for a certain degree of assembly error. Even if the vertical position of the central tube 12 is slightly offset, the U-shaped notch 121 can still align and connect the first channel port 211 and the second channel port 212. The U-shaped notch 121 is also relatively convenient in aligning the first channel port 211 and the second channel port 212, and connection can be achieved without precise alignment.

[0035] To further simplify the structure, reduce the number of parts, and improve production efficiency, in this embodiment, the upper cover 1, the pressing plate 11, and the central tube 12 can be designed as a single piece; the lower cover 2, the sleeve 21, the first nozzle 22, and the second nozzle 23 can also be designed as a single piece, preferably by injection molding. This design requires only two parts to achieve the spray conversion function, greatly simplifying the assembly process; assembly can be completed simply by plugging them together.

[0036] In order to reduce the overall weight and material cost, in this embodiment, the lower cover 2 is designed as a ring structure, the sleeve 21 is suspended in the center of the lower cover 2, and the sleeve 21 is integrally connected to the lower cover 2 only through the first nozzle 22 and the second nozzle 23.

[0037] The specific implementation of the press-lock structure is as follows: An inwardly extending support plate 24 is provided around the periphery of the lower cover 2. A limiting seat 25 is provided at the upper end of the support plate 24, and a limiting groove 251 is provided on the limiting seat 25 along the circumferential direction. A downwardly extending limiting post 13 is provided on the bottom surface of the free end of the press plate 11. When the central tube 12 is rotated, causing the sleeve 21 to close, the limiting post 13 moves precisely into the limiting groove 251 and is restricted by the limiting groove 251, preventing it from moving downwards, thereby locking the pressing action of the press plate 11. When the inner cavity of the sleeve 21 connects to the first nozzle 22 or the second nozzle 23, the limiting post 13 will be offset from the limiting seat 25 and located within the ring of the lower cover 2, thereby unlocking the pressing action of the press plate 11 and allowing the press plate 11 to be pressed down.

[0038] Preferably, the lower cover 2 is provided with an air-avoidance area located on both sides of the limiting seat 25.

[0039] To enhance the strength of the support plate 24 and improve the stability of the limiting seat 25, the support plate 24 can be arranged vertically and the limiting seat 25 can be arranged circumferentially, thus forming a T-shaped structure.

[0040] To further improve the sealing performance of the rotary seal structure, the rotary seal structure also includes a sealing convex ring 122 and a sealing concave ring 213 that cooperate to form a seal. Of the sealing convex ring 122 and the sealing concave ring 213, one is disposed on the inner side wall of the sleeve 21, and the other is disposed on the outer side wall of the central tube 12.

[0041] To prevent the central tube 12 from moving excessively downward within the sleeve 21, a retaining ring 214 is provided in the middle of the inner cavity of the sleeve 21, and a sealing ring 215 is provided between the lower end of the central tube 12 and the retaining ring 214 (e.g., a sealing ring 215). Figure 5 (As shown), to ensure a good seal.

[0042] Preferably, the portion of the inner cavity of the sleeve 21 located above the retaining ring 214 and the outer shape of the central tube 12 are both tapered, wider at the top and narrower at the bottom. This allows for closer contact between the outer wall of the central tube 12 and the inner wall of the sleeve 21 during press-and-jet injection, effectively preventing air or liquid leakage.

[0043] To limit the rotation range of the upper cover 1 and prevent damage to components from excessive rotation, a rotation limiting structure is provided between the upper cover 1 and the lower cover 2. This rotation limiting structure includes a left limiting protrusion 26 and a right limiting protrusion 27 disposed around the periphery of the lower cover 2, and a limiting head 14 disposed around the periphery of the upper cover 1. The limiting head 14 moves between the left limiting protrusion 26 and the right limiting protrusion 27 as the upper cover 1 rotates, thereby limiting the rotation range of the upper cover 1.

[0044] like Figure 2As shown, to facilitate user identification of the current spray mode and locking status, a nozzle 15 is provided on the side wall of the upper cover 1, and a side plate 28 is provided around the periphery of the upper cover 1. The first nozzle 22 and the second nozzle 23 are both connected to the side plate 28. A locking indicator 281 is provided on the outer surface of the side plate 28, located between the first nozzle 22 and the second nozzle 23. When the notch 121 is aligned with and connected to the first channel opening 211, the first nozzle 22 is precisely aligned with the nozzle 15. Pressing the press plate 11 at this time allows for the first mist spray. When the notch 121 is aligned with and connected to the second channel opening 212, the second nozzle 23 is precisely aligned with the nozzle 15. Pressing the press plate 11 at this time allows for the second mist spray. When the sleeve 21 is closed, the locking indicator 281 is precisely aligned with the nozzle 15, thus visually indicating that the pressing action has been locked.

[0045] As can be seen from the above embodiments, the aerosol actuator of this utility model has the characteristics of simple structure, easy assembly and low cost.
