The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

As shown in fig. 1, the leak-proof marking pen provided by the embodiment comprises a pen holder 1, a pen holder internal thread opening 2, a pen holder protrusion locking snap ring 3, a pen holder 4, a pen holder threaded opening 5, a first pen holder protrusion locking snap ring 6, a pen clip 7, a pen cap 8, a second pen cap internal protrusion locking snap ring 9, a hollow cylinder 10, a stainless steel fine wire high mesh screen 11, a fiber cylinder 12, a pen point 13, an ink sucking and storing device 14, a pressure rod 15 and a stainless steel spring 16.

The ink absorption and storage device 14 and the pressing rod 15 are integrated, the stainless steel spring 16 is placed inside the ink absorption and storage device 14, a gap is formed between the outer edge of the spring 16 and the inner edge of the ink absorption and storage device 14, and two ends of the spring 16 are respectively close to the inner wall of a plane where the ink absorption and storage device 14 is connected with the pressing rod 15 and the hollow cylinder 10.

The circular inner wall of the thick open end of the ink absorption and storage container 14 and the circular outer wall of the hollow cylinder 10 are tightly pressed together and bonded with glue so that they can withstand the repulsive force when the spring 16 is pressed, while preventing ink from leaking out therefrom.

The stainless steel filament high mesh screen 11 is embedded inside the hollow cylinder 10 at one side close to the stainless steel spring 16, and the plane of the screen 11 is parallel to the circular plane on the hollow cylinder 10, as shown in fig. 2. The screen is a stainless steel fine wire high-mesh screen made of 316 materials, and the mesh number is 500-700 meshes.

The fiber cylinder 12 is placed in the hollow cylinder 10, one cross section is close to the plane of the stainless steel filament high mesh screen 11, the other cross section is flush with the annular plane of the hollow cylinder 10 close to the pen point, and the rest contact surfaces are not provided with gaps, so that the hollow cylinder 10 is filled with the inner space.

The outer edge of the hollow cylinder 10 is tightly embedded in the pen holder 4, and the contact surface is bonded by glue to prevent ink from leaking out. The smaller end of the nib 13 is inserted into the circular hole in the middle of the pen holder 4, and the cross section of the nib is in contact with the fiber cylinder 12, so that the ink can penetrate through the stainless steel fine wire high-mesh screen 11, pass through the fiber cylinder 12, and slowly reach the nib 13 along the pen point, thereby realizing the writing purpose.

The penholder 1 and the pen holder 4 are screwed together through the thread openings on the upper surfaces of the penholder and the pen holder, as shown in fig. 3, the functions of protecting the ink absorption and storage device and facilitating the holding of the pen are achieved.

The pen cap 8 and the pen holder 4 are tightly sleeved on the pen holder 4 through the first pen holding protrusion locking snap ring 6 and the second pen holding protrusion locking snap ring 9, as shown in fig. 4, so that the purpose of sealing and protecting the pen point 13 is achieved. When the pen is used, the pen cap 8 is taken down and sleeved at the tail of the pen holder 1, and the protruding locking snap ring 9 is tightly sleeved on the protruding locking snap ring 3 of the pen holder 1, as shown in fig. 5, so that the pen cap 8 is prevented from being lost, and the pen holding comfort is improved.

By pressing the pressing rod 15, the stainless spring 16 is at the compressed position, and the ink sucking and storing tank 14 compresses the space thereof by reducing the folding angle of the edge, and discharges the air inside. When the pressure lever 15 is released, the elastic force of the spring 16 is released, and the elastic force acts to expand the ink suction and storage container 14 while the spring 16 acts as a plastic hose supporting the ink suction and storage container 14 to prevent it from being arbitrarily contracted and deformed, thereby forming a negative pressure in the air inside. The ink now passes along the gap provided by the nib 13 and the pen grip 4, see figure 6, through the fibre cylinder 12 and through the screen 11 into the ink reservoir 14. Thus, the ink suction is conveniently and rapidly completed; after the ink is sucked, the ink is adsorbed on the stainless steel fine wire high mesh screen 11, the fiber cylinder 12 and the pen point 13 due to certain surface tension, so that the ink cannot directly leak out, and the ink can be stored in a large amount of flowing liquid state. But only slowly permeate into the pen point to achieve the purpose of writing.

The embodiment makes an ink-tight design, and improves the utilization rate of ink; if the marking pen is not used for a long time, the residual ink in the marking pen can be squeezed out and dripped into an ink bottle for sealed storage. The waste and the pollution to the environment caused by the volatilization of the residual ink in the marking pen due to long-term shelf disuse are avoided.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
