Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a high-rigidity polymer material hand-operated sprayer with a strong detachable cover structure. Background Technology

[0002] In the cosmetics industry, sprayers, as convenient application tools, are widely used in the packaging and usage scenarios of products such as toners, moisturizing sprays, and setting sprays. To meet the demands of cosmetic packaging for structural stability, durability, and lightweighting, some existing cosmetic sprayers use high-rigidity polymer materials for their bottle bodies. These materials not only possess excellent mechanical strength, effectively preventing deformation and damage to the bottle during transportation or use, but also reduce the overall weight of the sprayer, improving ease of use.

[0003] To protect and seal the top pressing component of the sprayer, these sprayers typically feature a removable structure. The cover is attached to this structure via a snap-fit ​​mechanism, which not only protects the pressing head from dust and accidental contact but also facilitates user disassembly and use. However, current cosmetic sprayers of this type still present significant inconveniences during use: the spray is generally generated by continuously pressing the top pressing head, which drives the internal pump to dispense the spray. On the one hand, this pressing process often requires a certain amount of pressure, which can easily lead to fatigue for users with weaker hand strength. On the other hand, the need to maintain a pressing posture throughout spraying prevents the hand holding the bottle from flexibly adjusting its angle or position, especially when large-area spraying or prolonged use, resulting in poor operational flexibility and severely impacting the user experience.

[0033] Control lever 9 is connected to the top end of pressing lever 7 near the rotating shaft 8. The size of control lever 9 is larger than that of pressing lever 7, and the ends of control lever 9 and pressing lever 7 away from rotating shaft 8 are on the same side.

[0034] The top of the spray head 5 is provided with a limiting mechanism, which is used to limit the pressing rod 7 of the spray head 5.

[0035] In this embodiment,

[0036] Support rod 6: Installed at the top of the mounting ring 4 and symmetrically distributed, it provides a rotation support point for the pressing rod 7 and enables the pressing rod 7 to rotate flexibly by cooperating with the rotating shaft 8;

[0037] Pressing lever 7: It is rotatably connected to the support rod 6 via two rotating shafts 8 at both ends. The end away from the rotating shaft 8 slides and is in close contact with the spray head 5.

[0062] The working principle of this utility model is as follows:

[0063] In use, first remove the cover 3. Press the control lever 9 to drive the pressing lever 7 to rotate around the pivot 8 of the support rod 6. The pressing lever 7 slides down the spray head 5 through the convex arc surface, driving the pump body to spray cosmetics from the nozzle. During the pressing process, the control shaft 12 slides along the control groove 11. After reaching the position, it is locked into the arc groove 13 to achieve a limit. The spray head 5 remains in a pressed state, and spraying can continue without continuous force. When stopping use, push the control lever 9 upward, the control shaft 12 disengages from the arc groove 13, the spray head 5 resets and stops spraying, and the cover 3 can be re-fastened for protection. The stabilizing rod 10, extension plate 14, anti-slip protrusions 15 and other structures improve the convenience and comfort of pressing. The high rigidity material and symmetrical design ensure structural stability. Overall, it solves the problems of operator fatigue and poor flexibility of traditional sprayers. The high rigidity polymer material can be polypropylene or polyketone, and is not limited to these two materials.

[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
