- the existing solutions are to inject working fluid into the inner cavity of the rod body so that the rod body also serves as a container.
- This type of technical solution is used to make the working fluid in the inner cavity in use.
- you need to open two opening devices at the same time so that the upper end surface of the working fluid can pass through the atmosphere and the lower end surface can flow out; or the opening device of the lower end surface of the working liquid must be opened.
- Pressurized gas The problem is that there are many fixed sealing points, the process is complicated, and the material requirements are high, thereby reducing the convenience of use or greatly increasing the manufacturing cost.
- the capsule container 20 is fixedly sealed to the closed end of the tubular rod body 10, and has a simple structure, strict sealing, and low manufacturing cost.
- the closed end of the tubular rod body 10 of the present invention is provided with an easily broken tail tube 11 and is covered in a closed capsule-shaped container 20, which is not only easy to open, but also can use the pressure naturally generated when the finger is pressed against the capsule-shaped container 20 during use to make the capsule.
- the working liquid 60 and the gas 80 in the container are compressed, so that the working liquid 60 quickly flows out of the capsule container 20 and enters the inner cavity of the tubular rod body 10 immediately after the breakable tail pipe 11 is broken.
- the working liquid 60 entering the inner cavity of the tubular rod body 10 will quickly pass through the through hole 12 and the tubular rod body under the effect of gravity.
- the ports of 10 are all immersed in the soft absorbent body 30. Due to the function of the vent hole 13, the size of the capsular container 20 can be selected according to need, because the working liquid 60 only needs to be squeezed out of the capsular container 20, and the working liquid 60 can naturally flow into the soft absorbent body through the inner cavity of the tubular rod body 10. 30 .. In addition, since the vent hole 13 is higher than the position where the easily broken tail pipe 11 extends into the tubular rod body 10, the working fluid 60 does not overflow from the vent hole 13.

- the working fluid 60 naturally flows down and quickly penetrates the soft absorbent body 30 through the through hole 12 and the port of the rod body on the pipe wall, and is ready for use. Due to the function of the vent hole 13, no working fluid 80 remains in the tubular rod body 10.
- the gas-filled open type liquid-carrying wiper provided by the present invention has a gas 80 built into the capsule-shaped container 20 as nitrogen or purified air.
- Nitrogen is an inert gas, so the working liquid 60 will not be changed in any way.
- Other suitable gases can also be selected based on the principle that the properties of the working fluid must not be affected.
- the working liquid 60 built into the capsule-shaped container 20 of the folded liquid-opening liquid-carrying wiper provided by the present invention can select a volume ratio occupied by the gas 80 that is simultaneously placed. ⁇ Gas 80
- the working liquid 60 can be squeezed out of the sac container 20 with only one folding; if the volume occupied by the working liquid 60 is large until the sac container 20 is filled, it needs to wait after extrusion After the capsule container 20 is restored to its original shape, it is squeezed again, so that the working liquid 60 completely flows out, leaving no residual liquid.
- the vent hole 13 plays an indispensable role. It is also possible to put pressurized gas into the capsule containers 20 respectively, and the effect is the same, but the manufacturing cost will be increased accordingly.
- the folding open liquid-carrying wiper provided by the present invention also pre-draws a breakable line on the inner pipe wall of the tubular rod body 10 covering the soft absorbent body 30, so as to recover after use and discard the cotton head. ; Or use a cotton swab wrapped with a bamboo or wood core to insert the open end of the tubular rod body in a known manner instead of wrapping the cotton directly on the rod body. After use, break or pull out and discard the cotton head to recycle to meet environmental protection requirements.
- a non-wrapping method is used to connect a soft absorbent body 30 such as a cotton ball at the end of the tubular rod body 10, which overcomes the restriction of the rotating tubular body to the shaped tubular rod body. Due to the good elasticity of the soft absorber and the good toughness of the polymer materials (such as polyethylene, polypropylene, etc.), the longitudinal direction of the marginal band with convex teeth that tends to recover after being deformed by the force of the end of the rod 10 is deformed. The through hole 12 is firmly clamped, so the connection between the soft absorber 30 and the end of the rod body 10 is very stable;
- the tubular rod body 10 is provided with one end of a soft absorber 30, and is covered by a sleeve-shaped cover 40 connected to the rod body with three threads.
- a sleeve-shaped cover 40 connected to the rod body with three threads.
- the rod body 10 and the sleeve 40 form a ring-shaped end surface at a close fit. It is sealed, and the sleeve 40 and the annular rib in the capsule container 20 form a tight fit seal at b, so that the soft absorbent body 30 is kept tightly closed before the liquid-carrying wiper is opened and used, which can meet more High hygiene requirements.
- the sleeve 40 can be easily opened by only twisting 90 to 120 degrees during use.
- the stress-concentrating groove is provided at the root of the stress-concentrating tail tube 11, it is easy to break the circumferential direction. When the tube 11 is used, it can be broken easily. Because the root of the tail tube 11 is easily broken, no liquid will remain in the capsule container 20 during use. Since the thread seal of the rod body 10 is also provided with a longitudinal ventilation slot, Before the sleeve is unscrewed, the sleeve 40 is completely in communication with the gas between the rod body and the gas in the inner cavity of the rod. When the liquid 60 is squeezed into the inner cavity of the tubular rod from the capsule into the container 20, the gas is in the sleeve 40. It can circulate smoothly, so the liquid 60 can quickly enter the soft absorbent body 30.
