Problems solved by technology

But among the existing technical schemes, some are difficult to open; some work liquids cannot be discharged or exhausted because the top of the container storing the working liquid cannot be connected to the atmosphere; Molecules of volatile substances can penetrate through the gaps of silicone oil molecules and lose the continuous sealing effect; some use mechanical seals, and the sealing effect is greatly affected by factors such as the processing accuracy of sealing components, assembly quality, and ambient temperature; some A pressurized gas is placed in the container for storing the working liquid to assist the working liquid to flow out of the container, which requires too high airtightness of the container material, and the processing technology is complicated; some use bladder containers to store the working liquid, in order to ensure that each The function of the component and make it easy to open, it has to be bonded and fixed with the sealing element of different properties from the capsule container to form a closed container together, because different working liquids have different chemical properties, it is difficult to match the sealing elements used for bonding Adhesives coexist with various materials with different characteristics, which will not only greatly increase its manufacturing cost, but also affect the performance of the product

Embodiment

[0051]One of the embodiments: a micro-volume self-carrying liquid wiper, comprising a catheter 10 with two open ends and a capsule container 20 placed at the upper end of the catheter and a soft absorbent body 40 placed at the lower end of the catheter 10, its characteristics In that: the bottom of the capsule container 20 is fused and sealed with an end pipe 21 connected to its inner cavity, so that the capsule container 20 forms a self-closed chamber; an opening element 30 is placed in the self-close chamber; the self-close Gas 50 and working liquid 60 are also placed in the chamber; the lumen at the upper end of the catheter 10 communicates with the outside of the tube.

[0052] The sac-shaped container 20 is a pyramid-like sac-shaped container whose lower part communicates with the end tube 21 of the inner cavity and extends into the lumen of the catheter 10 and is socketed with the catheter 10 through the outer end tube.

[0053] The gas 50 contained in the self-enclosed ...

Abstract

An eraser carrying less liquid by itself is composed of a bag body containing air, working liquid and an opening element, a soft absorbing body and tube with two open ends and arranged between the former two. Pressing said bag body can force the working liquid into said absorbing body for erasing.

Description

field of invention [0001] The invention relates to a device for storing and wiping trace liquids, in particular to a trace self-carrying liquid wiper. Background of the invention [0002] In daily life, people often use a small amount of liquid, such as wiping the magnetic head of the tape recorder, the CD-ROM of the computer, and wiping the skin wound with alcohol. The amount of working liquid required for one time is generally less than one milliliter. The method of use is: store all kinds of working liquids in containers such as bottles, and then use soft absorbents such as cotton swabs to pick them up and then rub them. It has obvious disadvantages such as not easy to carry, difficult to store, and easy to volatilize and deteriorate the working liquid. [0003] In order to overcome the above-mentioned shortcomings, it is a good idea to use the wiping device as a container for storing a small amount of working liquid. But among the existing technical schemes, some are di...
