摘要： This is about liquid pens that are used on boards and blackboards (15). there is a back cap (1) which is consists of the male screw in the outside and has female screw structure, is connected to the cylinder(2). The inside the liquid cylinder body (2) has one steel ball and front side of the cylinder body (2) has male screw, and the outlet cap (4) is connected to the inside the liquid cylinder body (2). The elastic spring (6) is in the outlet cap and valve path (7) is connected into the inside the elastic spring. In the front of the valve path (7), there is a supporting bump(8), and this supporting bump is connected to the oil path (9), also the oil path (9) is in the cylinder cap (10) that is connected with the cylinder front and the oil path is projected in front of the cylinder cap (10). This projected oil path (9) is combined with the front cap (12) which is connected with the absorbing filter (11) to the inside, and in the front of the front cap (12) is connected with the fixed projected tip (13). This projected fixed tip (13) and the front cap (12) is connected with the front cover (14). The above is the main technique of this liquid pen. This pen has very practical function and shape. If the liquid is dried while you are using it, it opens the oil path (9) so the charged liquid can flow out. It can prevent the waste and evaporation of the liquid, also we can use the liquid in one action, so it is very convenient.
