Description

Technical Field

[0002] This application belongs to the technical field of liquid spraying bottles, and particularly relates to a sprayer nozzle with a limiting structure.

Background Art

[0004] As a convenient product form, aerosols are widely used in multiple fields such as cosmetics, cleaners, and pesticides. However, when aerosols are carried and stored, accidental release of aerosols may occur due to accidental pressing of the valve, resulting in waste and unnecessary damage. In traditional aerosol designs, the valve is usually directly exposed, making accidental pressing prone to happen. A common preventive measure is to add a lid around it. This method increases the inconvenience during the use and carrying of aerosols to a certain extent, and the lid is prone to be lost. The user experience is not good.

Utility Model Content

[0006] In order to solve the problem in the prior art that using a lid to prevent accidental pressing of the aerosol valve during carrying and storage causes inconvenience in use, this application provides a sprayer nozzle with a limiting structure.

[0007] This application is achieved through the following technical solutions:

[0008] A sprayer nozzle with a limiting structure includes a limiting mechanism, a mounting base for connecting an aerosol can, and a rotating cover rotatably connected to the mounting base. A pressing platform is connected to the rotating cover. The mounting base is provided with a first state position and a second state position. When the rotating cover rotates relative to the mounting base to the first state position, the limiting mechanism restricts the pressing platform from pressing down the aerosol valve; when the rotating cover rotates relative to the mounting base to the second state position, the limiting mechanism releases the restriction on the pressing platform from pressing down the aerosol valve.

[0009] For a sprayer nozzle with a limiting structure as described above, the limiting mechanism includes an abutting block provided below the pressing platform and a limiting block provided on the mounting base. When the abutting block corresponds to the limiting block, the rotating cover is in the first state position relative to the mounting base; when the abutting block is displaced from the limiting block, the rotating cover is in the second state position relative to the mounting base.

[0010] For a sprayer nozzle with a limiting structure as described above, the limiting block extends upward from the mounting base to abut against the abutting block.

[0011] For a sprayer nozzle with a limiting structure as described above, it includes two limiting blocks and two abutting blocks corresponding to the two limiting blocks respectively. The included angle between the two limiting blocks in the circumferential direction of the mounting base is 180 degrees.

[0012] A sprayer nozzle with a limiting structure as described above, a steam spraying channel is provided below the pressing platform, the steam inlet of the steam spraying channel faces downward, the steam outlet of the steam spraying channel is located on the side surface of the rotating cover, and the steam inlet is in a horn shape.

[0013] A sprayer nozzle with a limiting structure as described above, a circumferentially arranged clamping wall is provided on the mounting base, a flange is arranged on the inner side of the rotating cover along the circumference, and a clamping groove for the flange to be inserted into is formed between the clamping wall and the outer side wall of the mounting base.

[0014] A sprayer nozzle with a limiting structure as described above, a downwardly inclined chamfer is provided on the outer side of the top of the clamping wall.

[0015] A sprayer nozzle with a limiting structure as described above, a limiting post is further provided on the rotating cover, a sliding groove for the limiting post to slide is provided on the mounting base, a plurality of limiting strips are provided on the sliding groove, and the limiting strips limit the sliding distance of the limiting post along the sliding groove.

[0016] A sprayer nozzle with a limiting structure as described above, a plurality of anti-slip protrusions are provided on the side surface of the rotating cover.

[0017] A sprayer nozzle with a limiting structure as described above, further includes an atomizing sheet provided at the steam outlet of the steam spraying channel.

[0018] Compared with the prior art, the present application has the following advantages:

[0019] For the sprayer nozzle with a limiting structure of the present application, by rotating the rotating cover to the first state position and the second state position respectively, the pressing of the aerosol can valve by the pressing platform is restricted and the restriction is released, so that the aerosol will not spray out liquid due to accidental pressing during carrying and storage. Compared with the traditional method of adding a lid, this solution is more convenient to use, eliminates the overall design of the lid, improves the user experience, and at the same time avoids the loss of the effect of preventing accidental pressing of the valve due to the loss of the lid.

Detailed implementation manners

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] Please refer to Figures 1 to 7 , a sprayer nozzle with a limiting structure, including a limiting mechanism 1, a mounting base 2 for connecting an aerosol can, and a rotating cover 3 rotatably connected to the mounting base 2. A pressing platform 4 is connected to the rotating cover 3. The mounting base 2 is provided with a first state position 21 and a second state position 22. When the rotating cover 3 rotates relative to the mounting base 2 to the first state position 21, the limiting mechanism 1 restricts the pressing platform 4 from pressing down the aerosol can valve; when the rotating cover 3 rotates relative to the mounting base 2 to the second state position 22, the limiting mechanism 1 releases the restriction on the pressing platform 4 from pressing down the aerosol can valve.

[0032] A sprayer nozzle with a limiting structure of the present application realizes the restriction and release of the pressing of the aerosol can valve by the pressing platform by rotating the rotating cover to the first state position and the second state position respectively, so that the aerosol will not spray liquid due to accidental pressing during carrying and storage. Compared with the traditional method of adding a lid, this solution is more convenient to use, omits the overall design of the lid, improves the user experience, and at the same time avoids the loss of the lid and the effect of preventing accidental pressing of the valve.

[0033] Further, as a preferred implementation manner of this solution rather than a limitation, the limiting mechanism 1 includes an abutting block 11 provided below the pressing platform 4 and a limiting block 12 provided on the mounting base 2. When the abutting block 11 corresponds to the limiting block 12, the rotary cover 3 is in the first state position 21 relative to the mounting base 2. When the abutting block 11 and the limiting block 12 are misaligned, the rotary cover 3 is in the second state position 22 relative to the mounting base 2.

[0034] In this embodiment, when the abutting block 11 corresponds to the limiting block 12, the rotary cover 3 is in the first state position 21. At this time, the pressing platform 4 cannot press down the aerosol can valve, effectively avoiding the accidental release of the aerosol due to misoperation. When in use, just rotate the rotary cover 3 to the second state position 22. At this time, the abutting block 11 and the limiting block 12 are misaligned, and the pressing platform 4 can freely press down the aerosol can valve to achieve smooth spraying of the aerosol. This design not only simplifies the operation process but also improves the flexibility of product use and user experience.

[0035] Further, as a preferred implementation manner of this solution rather than a limitation, the limiting block 12 extends upward from the mounting base 2 to abut against the abutting block 11.

[0036] In this embodiment, the limiting block extends upward to a height where it abuts against the abutting block. This design ensures that there is no play between the two when the limiting block corresponds to the abutting block. Users can directly distinguish whether the current rotary cover is in the first state position or the second state position without prompts and only relying on touch. This direct contact design can provide a more reliable limiting effect and reduce the possibility of misoperation.

[0037] Further, as a preferred implementation manner of this solution rather than a limitation, it includes two limiting blocks 12 and two abutting blocks 11 corresponding to the two limiting blocks 12 respectively. The included angle between the two limiting blocks 12 in the circumferential direction of the mounting base 2 is 180 degrees.

[0038] In this embodiment, the two abutting blocks respectively abut against the corresponding limiting blocks, thus more firmly restricting the pressing platform from pressing down the aerosol can valve to achieve the best limiting effect.

[0039] Further, as a preferred implementation manner of this solution rather than a limitation, a steam spraying channel 5 is provided below the pressing platform 4. The steam inlet 51 of the steam spraying channel 5 faces downward, and the steam outlet 52 of the steam spraying channel 5 is located on the side of the rotary cover 3. The steam inlet 51 is in a flared shape.

[0040] In this embodiment, the flared design enlarges the opening, making it easier to position the steam inlet when connecting to the aerosol can valve and ensuring the sealing performance while enlarging the opening.

[0041] Further, as a preferred implementation manner rather than a limitation of this solution, a circumferentially arranged clamping wall 23 is provided on the mounting base 2, and a flange 31 arranged circumferentially is provided inside the rotary cover 3. A clamping groove 24 for the flange 31 to be inserted into is formed between the clamping wall 23 and the outer side wall of the mounting base 2.

[0042] In this embodiment, the rotary cover can be stably connected to the mounting base through the clamping groove. This clamping structure can not only provide sufficient connection strength to prevent the rotary cover from loosening or falling off during use, but also facilitate users to assemble and disassemble, improving the usability and reliability of the product. In the embodiment, the length of the clamping wall or the flange can be adjusted according to actual needs. The circumferentially arranged clamping wall or flange with segmented intervals can ensure the connection while also easily and labor-savingly separating the rotary cover from the mounting base.

[0043] Further, as a preferred implementation manner rather than a limitation of this solution, a downwardly inclined chamfer 25 is provided on the outer side of the top of the clamping wall 23.

[0044] In this embodiment, the opening of the clamping groove is made smoother, reducing the friction force during the insertion of the rotary cover, thereby improving the convenience of assembly and disassembly. At the same time, the design of the chamfer can also prevent the edge of the clamping groove from being too sharp, reducing the potential harm to the user's hand. The angle and length of the chamfer can be adjusted according to actual needs to achieve the best use effect.

[0045] Further, as a preferred implementation manner rather than a limitation of this solution, a limiting post 32 is also provided on the rotary cover 3, a sliding groove 26 for the limiting post 32 to slide and cooperate is provided on the mounting base 2, and a plurality of limiting strips 27 are provided on the sliding groove 26. The limiting strips 27 limit the sliding distance of the limiting post 32 along the sliding groove 26.

[0046] In this embodiment, precise control of the rotation angle of the rotary cover is achieved. When the rotary cover rotates to the first state position, the limiting post contacts the limiting strip in the sliding groove, restricting the further rotation of the rotary cover, thereby ensuring that the pressing platform does not press down the aerosol can valve; when the rotary cover rotates to the second state position, the limiting post separates from the limiting strip, releasing the restriction on the rotary cover and enabling it to continue rotating and be used normally. This design can provide a more accurate limiting effect, improving the reliability of the product and the user experience.

[0047] Further, as a preferred implementation manner rather than a limitation of this solution, a plurality of anti-slip protrusions 33 are provided on the side surface of the rotary cover 3.

[0048] In this embodiment, the grip friction of the user on the rotating cover is increased, enabling the user to rotate the cover more easily during use, thereby improving the convenience and comfort of use. At the same time, the design of the anti-slip protrusions can also increase the contact area between the rotating cover and the user's fingers, reducing the possibility of slipping and enhancing the safety of use. In the embodiment, the number, shape, and size of the anti-slip protrusions can be adjusted according to actual needs to achieve the best anti-slip effect.

[0049] Further, as a preferred implementation manner rather than a limitation of this solution, it further includes an atomization sheet 521 provided at the steam outlet 52 of the steam spray channel 5. In this embodiment, a cyclone groove 522 is provided on the atomization sheet 521, and the liquid material pressed out by the propellant of the aerosol is broken into an atomized state and sprayed out.

[0050] The working principle of this embodiment is as follows:

[0051] A sprayer nozzle with a limiting structure according to the present application realizes the limitation and release of the pressing of the aerosol can valve by the pressing platform by rotating the rotating cover to the first state position and the second state position respectively, so that the aerosol will not spray out liquid due to accidental pressing during carrying and storage. Compared with the traditional method of adding a cover, this solution is more convenient to use, eliminates the overall design of the cover, improves the user experience, and at the same time avoids the loss of the effect of preventing accidental valve pressing due to the loss of the cover.

[0052] The above are the implementation manners provided in combination with specific content, and it is not considered that the specific implementation of the present application is limited only to these descriptions. Any structure similar to the method of the present application, or any technical deduction or replacement made under the premise of the concept of the present application, should be regarded as the protection scope of the present application.
