Description

Technical Field

[0001] This utility model relates to the field of spray pump technology, specifically to a child-proof spray pump head. Background Technology

[0002] A spray pump is a device used to atomize liquids into fine particles. It is widely used in shampoos, insecticides, hair gels, and cosmetics. It primarily utilizes compressed air pressure to draw liquid from a reservoir, creating a mist. When compressed air passes through the nozzle, a low-pressure zone is created at the nozzle, causing the liquid in the reservoir to be drawn into the nozzle under atmospheric pressure, mixed with the compressed air, and then atomized and sprayed out.

[0003] In practical use, children's curiosity will drive them to play, which can be dangerous if no adult is present to supervise them. Therefore, existing technologies generally design dust covers on the surface of the pump head to prevent children from accidentally spraying. For example, Chinese patent application CN213058275U discloses a dual-bottle spray pump, which divides the inner cavity of the bottle into two liquid chambers by a partition. The two pump bodies are then connected by two pump bodies and a dual-pump connecting cap, so that the liquid comes out from the cap. This allows one spray pump to store two different liquids (the two liquids do not affect each other when mixed, and the mixture forms the liquid to be used), avoiding the risk of the mixed liquid deteriorating after long-term storage. At the same time, the dust cover needs to be rotated at a certain angle to be removed to prevent children from accidentally spraying.

[0004] However, in actual use, setting up a protective cover cannot effectively prevent children from accidentally spraying the product, because the protective cover is not locked to the pump head. Children with good dexterity can still rotate the dust cover at a certain angle to make it come off, which could lead to accidental spraying. Utility Model Content

[0005] Therefore, this utility model provides a child-proof spray pump head to solve the problem in the prior art where children remove the dust cover and thus accidentally spray the product because the anti-slip cover is not locked to the pump head body.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A child-proof spray pump head includes a pump head body, the top of which is provided with a dust cover to prevent children from accidentally spraying the spray.

[0008] The outer wall of the pump head body is provided with a snap-fit ​​assembly for fixing the pump head body and the dust cover;

[0009] The snap-fit ​​assembly includes a slide groove, in which a first snap plate is slidably fitted and connected, and a second snap plate is disposed on the surface of the first snap plate.

[0010] In a preferred embodiment, the pump head body includes a device body, the top of which is provided with a first locking block, and the dust cover includes a cover body, the inside of which is provided with a second locking block. The second locking block is engaged with the surface of the first locking block, thereby enabling the dust cover to be engaged with the surface of the pump head body to prevent accidental spraying by children.

[0011] In a preferred embodiment, the outer wall of the first card block has a notch, the size of which is adapted to the size of the second card block. The second card block can be removed from the notch, thus removing the dust cover. Children do not know how to remove it, which protects the children.

[0012] In a preferred embodiment, the surface of the device body is provided with an indicator block, and the surface of the cover body is provided with an indicator arrow, which can remind adults of the specific location of the notch, making it convenient for adults to rotate to this location and remove the dust cover.

[0013] In a preferred embodiment, the top of the first card plate is provided with a sliding groove, and the bottom end of the second card plate is provided with a triangular support frame. The outer wall of the triangular support frame is provided with a slider, which is fitted and slidably connected inside the sliding groove. When the dust cover is inserted into the surface of the pump head body, the slider on the surface of the dust cover will be inserted into the sliding groove, thereby further fixing the dust cover and the pump head body.

[0014] In a preferred embodiment, the top of the first card plate and the second card plate are engaged with a carding plate, and the bottom of the carding plate is provided with a carding post, which is located inside the sliding groove and the bottom of the carding post is engaged with the top of the slider.

[0015] The top of the snap-fit ​​plate is provided with a fixing block, and the top of the first snap-fit ​​plate is symmetrically provided with mounting ear plates. The mounting ear plates are respectively in contact with the two sides of the fixing block. The mounting ear plates and the fixing block are both provided with fixing pins. The fixing pins can lock the dust cover to the surface of the pump head body to prevent children from accidentally moving the second snap-fit ​​block into the notch during play, causing the dust cover to be removed and the pump head body to spray accidentally.

[0016] In summary, this utility model has the following advantages:

[0017] By setting a second locking block inside the main body of the dust cover, the second locking block is inserted into the notch. After the dust cover is inserted into the surface of the pump head body, the second locking block will lock into the first locking block, which can enable the dust cover to rotate 360° on the top of the pump head body. However, the second locking block inside the dust cover needs to be moved to the notch to remove the dust cover normally, and then the pump head body can be used to pump out the material in the bottle. The dust cover on the pump head body cannot be opened normally from other positions. Children do not know how to rotate the dust cover to the designated position on the pump head body to open the dust cover. This effectively prevents children from accidentally opening the dust cover and using the pump head body to pump out the material in the bottle.

[0018] Furthermore, by fixing a sliding groove to the surface of the head body, a first locking plate is slidably connected to the surface of the sliding groove. The first locking plate engages with a second locking plate on the surface of the cover body. At the same time, the second locking plate and the first locking plate are fixed by a fixing pin. Even if a child accidentally rotates to the notch, the child will not be able to remove the dust cover by lifting it up. The dust cover needs to be rotated to a designated position to open it. The dust cover can rotate 360° while the child is playing, which distracts the child's attention from the surface of the dust cover and prevents them from being curious about what is in the bottle under the pump head body, thus solving the problem of accidental spraying caused by the child's curiosity.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] like Figure 1-7 As shown, this utility model provides a child-proof spray pump head, including a pump head body 1, which includes a device body 11. A first locking block 14 is provided on the top of the device body 11. An image is provided on the surface of the device body 11. The image can be set according to the image on the surface of the bottle, so that the image on the surface of the device body 11 matches the image on the bottle. At the same time, an indicator block 12 is locked onto the surface of the device body 11. The indicator block 12 can be set into a circle, triangle, rectangle, or pentagon according to the image, so that the shape of the indicator block 12 fits the image and the indicator block 12 is not so abrupt on the surface of the device body 11, making it easier for children to know the specific function of the indicator block 12.

[0031] like Figure 2 As shown, a dust cover 2 is provided on the top of the pump head body 1 to prevent children from accidentally spraying the pump. The dust cover 2 includes a cover body 21, and a second locking block 23 is provided inside the cover body 21.

[0032] In order to fix the dust cover 2 to the surface of the pump head body 1, the second locking block 23 is locked onto the surface of the first locking block 14 to connect the dust cover 2 to the pump head body 1. At this time, when the dust cover 2 is rotating, the second locking block 23 can rotate appropriately inside the first locking block 14, which increases the fun of the dust cover 2.

[0033] In order to remove the dust cover 2, the outer wall of the first locking block 14 has a notch 13. The size of the notch 13 is adapted to the size of the second locking block 23. When an adult rotates the dust cover 2, the second locking block 23 moves into the notch 13 and can remove the dust cover 2.

[0034] However, during the rotation, adults cannot see where the notch 13 is located. In order to tell adults the location of the notch 13, the surface of the cover body 21 is provided with an indicator arrow 22. When the indicator block 12 is aligned with the notch 13, it can remind adults that the second locking block 23 has moved into the notch 13. At this time, adults need to unlock the dust cover 2 from the pump head body 1, and then they can easily take out the dust cover 2.

[0035] To ensure the dust cover 2 is securely fastened to the surface of the pump head body 1, a snap-fit ​​assembly 3 is provided on the outer wall of the pump head body 1 for fixing the pump head body 1 and the dust cover 2. Figure 4-7 As shown, the snap-fit ​​assembly 3 includes a slide groove 31, which is fixedly connected to the surface of the device body 11. A first snap plate 15 is slidably connected inside the slide groove 31. A second snap plate 24 is provided on the surface of the first snap plate 15 and is fixedly connected to the outer wall of the cover body 21.

[0036] As the second card block 23 is inserted into the notch 13, such as Figure 4 As shown, the top of the first card plate 15 is provided with a sliding groove 16, and at the same time... Figure 5 As shown, a triangular support frame 25 is provided at one bottom end of the second card plate 24, and a slider 26 is provided on the outer wall of the triangular support frame 25. The slider 26 will be inserted into the sliding groove 16 to further fix the dust cover 2 and the pump head body 1.

[0037] The above only achieves longitudinal fixation of the first clamping plate 15 and the second clamping plate 24. For lateral fixation of the first clamping plate 15 and the second clamping plate 24, as follows... Figure 7 As shown, the top of the first card plate 15 and the second card plate 24 are engaged with a carding plate 32. The bottom of the carding plate 32 is provided with a carding post, which is located inside the sliding groove 16. The bottom of the carding post is engaged with the top of the slider 26. The top of the carding plate 32 is provided with a fixing block. The top of the first card plate 15 is symmetrically provided with mounting ear plates 17. The mounting ear plates 17 are in contact with both sides of the fixing block. The mounting ear plates 17 and the fixing block are both provided with fixing pins 33.

[0038] When an adult needs to lock the protective cover, a fixing pin 33 can be inserted inside the mounting ear plate 17 and the fixing block to achieve longitudinal fixation of the first locking plate 15 and the second locking plate 24, while simultaneously locking the dust cover 2 onto the surface of the pump head body 1. When a child rotates the dust cover 2, the cover body 21 can slide along the slide groove 31 with the first locking plate 15. Even if the child accidentally rotates the dust cover 2 to the notch 13, the dust cover 2 will still be locked onto the surface of the pump head body 1. Even if the child lifts it up, the dust cover 2 will not be removed, and the child will not know how to unlock the dust cover 2. The dust cover 2 needs to be rotated to a designated position to open it. At this time, the dust cover 2 can rotate 360° while the child is playing, which distracts the child's attention from the surface of the dust cover 2 and prevents them from being curious about what is in the bottle below the pump head body 1, thus solving the problem of accidental spraying caused by the child's curiosity.
