The anti-dry plate is adhered and sleeved in the pen holder, an anti-dry hole is formed in the anti-dry plate, a baffle is arranged on one side of the anti-dry hole, anti-leakage plates are respectively arranged on two sides of the baffle, the anti-leakage plates are contacted with the inner wall of the pen holder, an adjusting plate is arranged on the outer side of each anti-leakage plate, an adjusting groove is formed in the side wall of the pen holder, and the adjusting groove is sleeved on the adjusting plate. And a liquid adding device is arranged on the outer side of the pen cap. The watercolor pen is convenient to reuse, capable of preventing the watercolor liquid from leaking out, convenient to add the watercolor liquid, high in stability, capable of preventing the pen point from being dry and convenient to observe the color and the capacity of the watercolor liquid, and used for overcoming the defects in the prior art.

Description

technical field [0001] The invention relates to a watercolor pen, in particular to an anti-drying capsule type watercolor pen. Background technique [0002] At present, the watercolor pens on the market cannot be recycled, so the watercolor pens can only be discarded after use, resulting in garbage that pollutes the environment and wastes resources. However, when the volume of the watercolor pen contains less watercolor liquid, the water color is easy to use up, which affects the use effect of the watercolor pen. Leakage from the gap will waste the watercolor liquid and affect the appearance of the watercolor pen; in addition, when the volume of the watercolor pen will be squeezed by inertia, the watercolor liquid will leak from the gap of the pen head or pen holder of the watercolor pen, which will affect the use of the watercolor pen . And when the watercolor pen is not used for a long time, the watercolor pen is easy to dry, which affects the use of the watercolor pen. ...

Problems solved by technology

[0002]Currently, the watercolor pens on the market cannot be recycled, so the watercolor pens can only be discarded after use, resulting in garbage that pollutes the environment and wastes resources

However, when the volume of the watercolor pen contains less watercolor liquid, the water color is easy to use up, which affects the use effect of the watercolor pen. Leakage from the gap will waste the watercolor liquid and affect the appearance of the watercolor pen; in addition, when the volume of the watercolor pen will be squeezed by inertia, the watercolor liquid will leak from the gap of the pen head or pen holder of the watercolor pen, which will affect the use of the watercolor pen

Moreover, if the watercolor pen is not used for a long time, the watercolor pen is easy to dry, which affects the use of the watercolor pen

[0003] For this reason, Chinese patent application number: 201120379524.8 discloses a new type of watercolor pen, which includes a rubber water storage bag between the top cover and the fixed partition. Press the water storage bag to refill the watercolor pen core with watercolor liquid. After the water color in the water storage bag is used up, the water storage bag can be replaced to effectively avoid waste, but the water storage bag needs to use a softer material to squeeze out the water. Rubber material, so it is easy to be crushed during carrying, which is not convenient to carry

Moreover, the Chinese patent application number: 201821185002.2 discloses an anti-drying watercolor pen, including an extruded structure made of a hydrophilic material, preferably a sponge; by extruding the extruded structure to remove moisture, The nib in contact with the extruded structure absorbs the water removed from the extruded structure, thereby eliminating the dryness of the nib and making full use of the ink, but it is easy to be squeezed during the carrying process, causing water to leak from the nib, affecting the use of the watercolor pen
