Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a pressure-resistant polymer vacuum hose nozzle based on a strong pressure structure. Background Art

[0002] Cosmetic containers are generally composed of a cylindrical or ellipsoidal container and a piston placed at the bottom. The design principle is to use the contraction force of the spring to prevent air from entering the bottle, creating a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward.

[0003] After searching, the utility model with announcement number CN213962203U discloses a cosmetic slap-in spray nozzle hose, and its technical solution is: it includes a spray nozzle body and a disassembly mechanism, a pump body is arranged at the bottom of the spray nozzle body, a connecting block is arranged at the bottom of the pump body, and a shell is arranged at the bottom of the connecting block. The beneficial effect of the cosmetic slap-in spray nozzle hose is: the use effect of the cosmetics is achieved through the coordinated use of the spray nozzle body, the pump body and the tube body, and the tube body is separated from the support block through the coordinated use of the first clamping block, the first clamping slot, the second clamping block and the second clamping slot, so as to achieve the disassembly effect of the tube body, which solves the problem that the hose with a pump head on the market is currently in daily use, because the hose itself is integrated and does not have a detachable function, which leads to the user's inability to disassemble the hose, and then the dirt in the hose cannot be cleaned, which brings inconvenience to the user's life.

[0004] The nozzle hose also has the following disadvantages during use: it is detachable to facilitate cleaning, but the straw at the bottom is soft and cannot fit completely on the bottom of the bottle during use, so that the material at the bottom of the bottle cannot be completely sucked up, and when the bottle is inverted, the bottom end of the hose cannot automatically extend into the liquid, so that suction cannot be made, which is very inconvenient to use. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art that the bottom straw is soft and cannot be completely attached to the bottom of the bottle during use, so that the material at the bottom of the bottle cannot be completely sucked up, and when the bottle is inverted, the bottom end of the hose cannot automatically extend into the liquid, making it impossible to suck and very inconvenient to use. A pressure-resistant polymer material vacuum hose nozzle based on a strong pressure structure is proposed to solve the shortcomings.
