Description

Technical Field

[0001] The utility model relates to the technical field of marker pens, in particular to a writing and erasing integrated marker pen. Background Art

[0002] Marker pen, also known as a marker pen, is a kind of colored drawing pen used for writing or drawing. It contains ink and is usually capped. It usually has a hard or soft pen head and a double head, one small head and the other large head.

[0003] Since lab oil-based markers are often placed in a heated water bath or high-temperature baking equipment, oil-based markers are generally used. There are currently two types of oil-based markers used in labs: one is a single-headed oily pen tip, and the second is a double-headed pen tip of different sizes. However, since lab personnel sometimes make mistakes and most containers are reusable, the written text must be removed. The current solution is to dip some anhydrous ethanol on cotton wool and then wipe it off, so it is troublesome every time you make a mistake or clean the writing on the container. Utility Model Content

[0004] The utility model aims to provide a writing and erasing integrated marker pen, which can greatly shorten the time caused by writing errors during the writing process and improve work efficiency. In addition, the product can be filled with ink and ethanol to increase the reuse rate and reduce costs.

[0005] To achieve the above purpose, a writing and wiping integrated marker pen is provided, comprising: an ink tube and an anhydrous ethanol tube, the upper end of the ink tube is fixedly connected to the lower end of the anhydrous ethanol tube, a pinhole pen tip is installed in the middle of the lower end of the ink tube, and the pinhole pen tip is connected to the ink tube, a wiping head is installed in the middle of the upper end of the anhydrous ethanol tube, and the wiping head is connected to the anhydrous ethanol tube, the side ends of the ink tube and the anhydrous ethanol tube are respectively provided with injection ports, a sealing cover is installed in the injection port, the lower end of the ink tube is equipped with a second pen cap, and the pinhole pen tip is located in the second pen cap, the upper end of the anhydrous ethanol tube is equipped with a first pen cap, and the wiping head is located in the first pen cap. It can greatly shorten the time caused by pen errors during writing, improve work efficiency, and the product can be added with ink and ethanol, improve reuse rate, and reduce costs.

[0006] According to the writing and erasing integrated marker, the sealing cover includes a knob and a threaded column, the threaded column is fixedly connected to the middle part of the side end of the knob, the inner wall of the liquid injection port is provided with an internal thread groove, the threaded column is located in the liquid injection port and is threadedly connected with the internal thread groove, so as to seal the marker to prevent the liquid inside the marker from leaking or being contaminated, which would affect the service life.

[0007] According to the writing and erasing integrated marker pen, a groove is provided in the middle of one end of the threaded column, and the groove is away from the knob, so as to avoid excessive air pressure in the marker pen when the sealing cap seals the marker pen, causing the liquid in the marker pen to spray out from the working end.

[0008] According to the writing and erasing integrated marker, the side end of the anhydrous ethanol tube is fixedly connected with a soft glue pressing block, and the soft glue pressing block penetrates the anhydrous ethanol tube and extends into the interior of the anhydrous ethanol tube, and the soft glue pressing block is located above the injection port, which is used to increase the air pressure in the anhydrous ethanol tube, and use the ethanol flowing out of the external pressure to take away the excess ink remaining on the fiber, so as to ensure the marker pen's effect of removing handwriting.

[0009] According to the writing and erasing integrated marker, the soft glue pressing block is made of silicone material, and the length of the soft glue pressing block is 2 cm and the width is 1.5 cm, so that the thumb of the user can fit it, which is convenient for the user to press.

[0010] According to the writing and erasing integrated marker, the ink tube and the anhydrous ethanol tube are 15 cm long and 2 cm in diameter, the pinhole pen tip is a carbon fiber with a diameter of 0.2 cm, and the wiping head is a carbon fiber with a diameter of 0.5 cm. The wiping head is larger than the width of the writing written by the marker to ensure the efficiency of cleaning the writing.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The combination of the ink tube and the anhydrous ethanol tube allows the marker to be applied in one piece, which is convenient for the staff to wipe the writing when making a mistake, and the used liquid can be added to the ink tube and the anhydrous ethanol tube respectively through the liquid injection port, thereby extending the service life of the marker.

[0013] 2. Use a soft rubber pressing block to increase the air pressure in the anhydrous ethanol tube, and use the ethanol flowing out of the external pressure to take away the excess ink remaining on the fiber, ensuring the marker pen's ability to remove writing.

[0014] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
