Description

Technical Field

[0001] This invention relates to the field of spray bottle technology, and in particular to a twist-type sprayer. Background Technology

[0002] A spray bottle is a bottle with a nozzle. By pressing the nozzle or squeezing the soft container wall, you can control the spray bottle to spray a mist of liquid. It is commonly used to hold liquids such as perfume, hairspray, water, cleaning agents, and medicines. However, ordinary spray bottles are prone to misuse and inconvenience if squeezed in bags or similar places.

[0003] A rotary self-locking press-type spray cap, with announcement number CN214637502U, includes a fixed base. A rotating cap is fitted onto the upper side of the fixed base. The rotating cap can rotate relative to the fixed base to a locked position and an unlocked position. A press-type spray head is provided on the fixed base, and a press button is provided on the rotating cap. The press button is used to press the press-type spray head downward when the rotating cap is rotated to the unlocked position. A pressure-limiting mechanism is provided between the press button and the fixed base to limit the downward pressure of the press button when the rotating cap is rotated to the locked position. By rotating the rotating cap to the locked position, the pressure-limiting mechanism can limit the downward pressure of the press button, thereby preventing accidental operation of the spray head and resulting in liquid spraying.

[0004] The above-mentioned patent has the following defects: Although the press-button cover can be locked by rotating the cap to the locking position to prevent accidental operation, the nozzle cannot be dustproofed after use, and some dust and other impurities can easily accumulate at the nozzle. Summary of the Invention

[0005] In order to improve the dustproof effect by having both anti-misoperation and dustproof functions, this application provides a twisting sprayer.

[0006] The torsion sprayer provided in this application adopts the following technical solution:

[0007] A twist-type sprayer includes a bottle body with a nozzle, a lower seat, and a cap. The lower seat has a placement groove for placing the bottle body. The cap is fitted onto the lower seat and can rotate and slide up and down. The cap has a mounting groove, and the nozzle is fixedly installed in the mounting groove. The cap has a spray outlet for the nozzle to spray. A sealing limiting plate is provided between the lower seat and the cap. The lower seat includes a locking position and a spraying position. When the cap rotates to the locking position, the sealing limiting plate seals the spray outlet and restricts the cap from sliding up and down. When the cap rotates to the spraying position, the spray outlet opens and the cap can slide up and down.

[0008] By adopting the above technical solution, when needed, the cover can be rotated to the spraying position. The sealing limit plate does not seal the spray outlet and does not restrict the up-and-down sliding of the cover. After pressing the cover, it can be used normally. When finished, the cover can be rotated to the locking position. At this time, the sealing limit plate can seal the spray outlet and restrict the up-and-down sliding of the cover at the same time. Thus, the sprayer of this application can achieve the effects of dust prevention and prevention of misoperation by simply rotating the cover, and it is convenient and quick to use.

[0009] Optionally, the sealing limiting plate is fixedly mounted on the lower seat. When the cover is rotated to the spray position, the cover is provided with a through hole for the sealing limiting plate to pass through. When the cover is rotated to the locking position, the sealing limiting plate abuts against the inner bottom wall of the mounting groove.

[0010] By adopting the above technical solution, when the cover is rotated to the spray position, the sealing limit plate can pass through the through hole during the pressing of the cover, so as to realize the normal pressing of the cover; when the cover is rotated to the locking position, the sealing limit plate abuts against the inner bottom wall of the mounting groove, so that the cover cannot be pressed down normally, thus playing a locking role.

[0011] Optionally, the inner wall of the mounting groove is provided with a rotating groove for the sealing limiting plate to slide along the inner wall of the mounting groove. The sealing limiting plate is slidably connected in the rotating groove. The sealing limiting plate is provided with a vertically extending sliding groove. The lower seat is provided with a slider. The slider is slidably disposed in the sliding groove. When the cover rotates to the locked position, the rotating groove is provided with a movable limiting plate that restricts the sliding of the slider. The sealing limiting plate is provided with an entry groove for the movable limiting plate to enter. The entry groove and the sliding groove are interconnected. When the cover rotates to the locked position, the movable limiting plate passes through the entry groove and extends into the sliding groove to limit the slider vertically.

[0012] By adopting the above technical solution, when the cover is rotated to the spray position, during the pressing of the cover, the slider on the lower seat can slide freely up and down in the groove of the sealing limiting plate to achieve normal pressing of the cover, and the sealing limiting plate will not extend outside the cover body during the pressing process; when the cover is rotated to the locking position, the movable limiting plate will pass through the inlet groove and extend into the groove to limit the slider up and down, so that the cover cannot be pressed down normally, thus playing a locking role.

[0013] Optionally, the cover is provided with a telescopic groove, which is connected to the rotating groove. The movable limiting plate is slidably disposed in the telescopic groove. A spring is provided in the telescopic groove. One end of the spring is connected to the movable limiting plate, and the other end is connected to the bottom wall of the telescopic groove. The movable limiting plate is an arc surface relative to the other end of the spring. When the cover is rotated to the locked position, the movable limiting plate is a plane relative to the slider.

[0014] By adopting the above technical solution, during the sliding process, when the edge of the sealing limiting plate abuts against the arc surface of the movable limiting plate, it will push the movable limiting plate back into the telescopic groove, allowing the sealing limiting plate to continue moving. When the movable limiting plate is aligned with the inlet groove, the movable limiting plate will extend through the inlet groove into the slide groove under the action of the spring to limit the slider. During the return movement of the sealing limiting plate, the edge of the inlet groove will abut against the arc surface of the movable limiting plate and push the movable limiting plate back into the telescopic groove, allowing the sealing limiting plate to return normally.

[0015] Optionally, the lower seat is provided with elastic plates on the left and right sides of one end of the cover, the end of the elastic plate is provided with a hook, and the inner wall of the mounting groove is provided with a protruding ring that engages with the hook.

[0016] By adopting the above technical solution, when the cover is fitted onto the lower seat, the hook on the elastic plate can be engaged with the protruding ring, so that the cover and the lower seat are not easy to fall off during normal use of the torsion sprayer.

[0017] Optionally, when the cover is rotated to the locking position, a first limiting block is provided in the mounting groove to limit the sealing limiting plate; when the cover is rotated to the spraying position, a second limiting block is provided in the mounting groove to limit the sealing limiting plate.

[0018] By adopting the above technical solution, the setting of the first and second limiting blocks allows the operator to quickly rotate the cover to the locking or spraying position, making the operation more convenient and faster.

[0019] Optionally, the hook is provided with an arc-shaped positioning groove. When the cover is rotated to the locking position, the convex ring is provided with a first arc-shaped positioning block that matches the arc-shaped positioning groove. When the cover is rotated to the spraying position, the convex ring is provided with a second arc-shaped positioning block that matches the arc-shaped positioning groove.

[0020] By adopting the above technical solution, the setting of the arc positioning groove, the first arc positioning block and the second arc positioning block can position the cover after it is rotated to the locking position or the spraying position, so that the cover is not easy to rotate without human intervention.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The sprayer of this application has both dustproof and anti-misoperation functions, and is convenient and quick to operate. Simply rotate the cover to open the spray nozzle and lock the cover, and then rotate the cover back to close the spray nozzle and unlock the cover. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] Example 1: This application discloses a twisting sprayer. (Refer to...) Figure 1 and Figure 2The rotary sprayer includes a lower base 3, a bottle body 1, a nozzle 2, and a cap 4. The lower base 3 has a placement groove 5 for the bottle body 1, which is placed inside. The cap 4 has an mounting groove 6, and the nozzle 2 is fixedly mounted in the mounting groove 6. The cap 4 is fitted onto the lower base 3 and can rotate and slide up and down. The nozzle 2 is mounted on the bottle body 1, and a tube on the bottle body 1 is inserted into the hole of the nozzle 2 (the bottle body 1 is a prior art type that can spray liquid when pressed, and will not be described in detail here). Liquid can be sprayed from the nozzle 2 when it is pressed. The cap 4 has a spray outlet 7 for the nozzle 2 to spray. A sealing limiting plate 8 is fixedly mounted on the lower base 3, and the cap 4 has... The lower seat 3 includes a locking position 9 and a spraying position 10, through which the sealing limiting plate 8 passes. When the cover 4 is rotated to the locking position 9, the sealing limiting plate 8 seals the spray outlet 7, making it difficult for external impurities to enter the sprayer. The sealing limiting plate 8 abuts against the inner bottom wall of the mounting groove 6, which can restrict the up and down sliding of the cover 4 and prevent misoperation. When the cover 4 is rotated to the spraying position 10, the spray outlet 7 is opened, the sealing limiting plate 8 does not block the spray outlet, and the spray outlet can spray liquid normally. The sealing limiting plate 8 is aligned with the through hole 11. During the pressing of the cover 4, the sealing limiting plate 8 can pass through the through hole 11, and the cover 4 can slide up and down normally, allowing the sprayer to spray normally.

[0033] Reference Figure 1 and Figure 2 Elastic plates 20 are provided on the left and right sides of the lower seat 3 relative to the end of the cover 4. Each elastic plate 20 has a hook 21 at its end, with a chamfered structure. A protruding ring 22 is provided on the inner wall of the mounting groove 6 to engage with the hook 21. An arc-shaped plate 28 is provided on the end of the lower seat 3 between the two elastic plates 20, opposite to the sealing and limiting plate 8. During the process of pressing the cover 4 onto the lower seat 3, the elastic plates 20 deform under force. The hook 21, after passing through the protruding ring 22, engages with the protruding ring 22, making it difficult for the lower seat 3 and the cover 4 to separate. The arc-shaped plate 28 abuts against the inner wall of the protruding ring 22, preventing the cover 4 from wobbling after installation.

[0034] Reference Figure 3 and Figure 4 When the cover 4 is rotated to the locking position 9, a first limiting block 23 is provided in the mounting groove 6 to limit the sealing limiting plate 8. When the cover 4 is rotated to the spraying position 10, a second limiting block 24 is provided in the mounting groove 6 to limit the sealing limiting plate 8. The setting of the first limiting block 23 and the second limiting block 24 allows the operator to quickly rotate the cover 4 to the locking position 9 or the spraying position 10, making the operation more convenient and faster.

[0035] Reference Figure 2 and Figure 3 An arc-shaped positioning groove 25 is provided on the end face of the hook 21 facing the convex ring 22. When the cover 4 rotates to the locking position 9, a first arc-shaped positioning block 26 that matches the arc-shaped positioning groove 25 is provided on the convex ring 22. When the cover 4 rotates to the spraying position 10, a second arc-shaped positioning block that matches the arc-shaped positioning groove 25 is provided on the convex ring 22. When the first arc-shaped positioning block 26 or the second arc-shaped positioning block is engaged in the arc-shaped positioning groove 25, the cover 4 is not easily rotated without human intervention. When the cover 4 is rotated forcefully, the first arc-shaped positioning block 26 or the second arc-shaped positioning block can be removed from the arc-shaped positioning groove 25.

[0036] The implementation principle of a twist-type sprayer in this application embodiment is as follows: When the sprayer needs to be used, simply rotate the cover 4 quickly. When the sealing limiting plate 8 touches the second limiting block 24, the second arc positioning block will engage in the arc positioning groove, that is, the cover 4 rotates to the spray position 10, the spray nozzle opens, the sealing limiting plate aligns with the through hole 11, and the sprayer can be pressed normally for spraying. During the pressing of the cover 4, the sealing limiting plate can pass through the through hole 11. After use, simply rotate the cover 4 quickly again. When the sealing limiting plate 8 touches the first limiting block 23, the first arc positioning block 26 will engage in the arc positioning groove, that is, the cover 4 rotates to the locking position 9, the sealing limiting plate 8 seals the spray nozzle, and the sealing limiting plate 8 is misaligned with the through hole. The sealing limiting plate 8 can restrict the up and down movement of the cover 4, thus preventing misoperation.

[0037] Example 2, refer to Figure 5 and Figure 6 The main difference between Embodiment 2 and Embodiment 1 is that: a rotating groove 12 is provided on the inner wall of the mounting groove 6 for the sealing limiting plate 8 to slide along the inner wall of the mounting groove 6. The sealing limiting plate 8 is slidably connected in the rotating groove 12. A sliding groove 13 extending vertically is provided on the sealing limiting plate 8. A slider 14 is provided on the lower seat 3. The slider 14 is slidably disposed in the sliding groove 13. When the cover 4 rotates to the locking position 9, a movable limiting plate 15 is provided in the rotating groove 12 to restrict the sliding of the slider 14. An entry groove 16 is provided on the sealing limiting plate 8 for the movable limiting plate 15 to enter. The entry groove 16 is connected to the sliding groove 13. When the cover 4 rotates to the locking position 9, the movable limiting plate 15 passes through the entry groove 16 and extends into the sliding groove 13 to limit the slider 14 vertically.

[0038] Reference Figure 5 and Figure 6The cover 4 is provided with a telescopic groove 17, which is connected to the rotating groove 12. The movable limiting plate 15 is slidably disposed in the telescopic groove 17. A spring 18 is provided in the telescopic groove 17. One end of the spring 18 is connected to the movable limiting plate 15, and the other end is connected to the bottom wall of the telescopic groove 17. The other end of the movable limiting plate 15 relative to the spring 18 is an arc surface 19. When the cover 4 is rotated to the locking position 9, the side of the movable limiting plate 15 relative to the slider 14 is a plane 27.

[0039] The implementation principle of the torsion sprayer in this embodiment is as follows: When the sprayer needs to be used, simply rotate the cover 4 quickly. The slider 14 on the lower seat 3 will drive the sealing limiting plate 8 to move within the rotating groove 12, gradually opening the spray nozzle. The movable limiting plate 15 moves out of the sliding groove 13. When the sealing limiting plate 8 touches the second limiting block 24, the second arc positioning block will engage with the arc-shaped positioning groove. That is, the cover 4 rotates to the spraying position 10, the spray nozzle is fully open, and the slider 14, no longer constrained by the movable limiting plate 15, can move freely within the sliding groove 13. The cover 4 slides up and down, allowing the sprayer to be pressed and sprayed normally. During the pressing process, the sealing limit plate 8 will not protrude outside the cover 4. After use, simply rotate the cover 4 quickly. When the sealing limit plate 8 touches the first limit block 23, the first arc positioning block 26 will engage in the arc positioning groove, that is, the cover 4 rotates to the locking position 9. At this time, the movable limit plate 15 will pass through the inlet groove 16 and extend into the slide groove 13 to limit the slider 14 up and down, so that the cover 4 cannot be pressed down normally, thus locking and preventing misoperation.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
