Description

Technical Field

[0001] The utility model belongs to the technical field of marker pens, in particular to an ink bag ejection structure for marker pens. Background Art

[0002] A marker pen, also known as a marking pen, is a colored drawing pen that contains ink sac water and usually comes with a pen cap. It has a hard or soft pen tip and a double-head design, one end is a small head and the other end is a large head. The pigment of the marker pen is volatile and is very suitable for one-time quick drawing.

[0003] In the prior art, the ink capsule of the marker pen needs to be replaced after the ink capsule is used up so as to continue to be used. However, the marker pen can be continued to be used without replacing the outer shell.

[0034] Working principle: During operation, the replaceable ink bag 1 is limited and fixed by the repulsive force of the first spring 15 and the limiting rod 14. The first slide groove 12 that slides in the middle of the second slide groove 16 can contact the limiting setting of the limiting rod 14 when the limiting rod 14 rotates to the inside of the third slide groove 17, so that the replaceable ink bag 1 can be taken out from the inside of the rotating shell 11. When the replaceable ink bag 1 is rotated to make the limiting rod 14 enter the inside of the third slide groove 17, and then when the rotating shell 11 is rotated to make the limiting block 22 slide on the inner wall of the fourth slide groove 2 to the inside of the fifth slide groove 26, the repulsive force of the second spring 24 will push out the limiting block 22 and the mounting plate 21, and the replaceable ink bag 1 that needs to be replaced is pushed out from the inner wall of the rotating shell 11, and the replacement ink bag 1 that needs to be replaced is pushed out from the inner wall of the rotating shell 11. The plate 25 can guide the ink at the temporal part of the replaceable ink bag 1, and the sealing glass bead of the replaced new ink bag can be pushed open through the top tube 3 so that the ink bag can output ink. When it enters the fifth slide groove 26 through the mounting plate 21 and is ejected, the top tube 3 will be driven to be ejected together. At this time, the ink blocking ball 41 will be input into the empty ink bag output port to block it, because the squeezing will cause the breaking rod 4 to break, reducing the splashing of residual ink in the ink bag during replacement. When the rotating shell 11 rotates, the sponge 5 will clean the inner wall of the rotating shell 11 to reduce the accumulation of ink impurities on the inner wall of the rotating shell 11. The support tube 6 installed in the middle of the sponge 5 can support the sponge 5 to reduce the deformation of the sponge 5 during cleaning when the rotating shell 11 rotates.
