Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] One end of the inner ink sac is connected to the ink pick-up, and the other end is connected to the nib, and the inner ink sac and the ink pick-up are placed in the outer ink storage. The nib is placed outside the external ink reservoir. The inner wall of the outer ink reservoir and the outer wall of the inner ink bag are tightly connected by glue.

[0015] The outer ink storage is provided with upper and lower sections respectively, which are tightly connected by threads, an air passage is provided on the upper section of the ink storage, and a breathable and waterproof membrane (1.1.1) is arranged inside the air passage (1.1).

[0016] The ink taker (3) is equipped with a restrictor tube (3.1) and a drainage core (3.2). When an internal ink-taking color pen is turned upside down, the drain core (3.2) absorbs ink and gradually expands, limited by the space of ...

Abstract

The invention relates to a watercolor pen, in particular to a watercolor pen with ink actively taken by an operator. An existing watercolor pen has the problems of small ink storage capacity, uncontrollable ink discharging speed and short service life. In order to overcome the defects of the existing watercolor pen, the invention provides a technology for an operator to take ink actively and control the output speed, so that the watercolor pen has a better use effect. According to the technical scheme, the ink internally-taking watercolor pen consists of an external ink storage device, an internal ink bag, an ink taking device and a pen point. The external ink storage device is provided with an air passage, an air permeable waterproof membrane is arranged in the air passage, and the uppersection and the lower section of the external ink storage device are connected through threads. One end of the internal ink bag is connected with the pen point, and the other end of the internal ink bag is connected with the ink taking device. The ink is stored in the external ink storage device, the watercolor pen is inverted when the operator takes ink, the ink enters the internal ink bag through the ink taking device, and the ink in the internal ink bag enters the pen point after the watercolor pen is put upright. The ink taking device is composed of a flow-limiting pipe and a flow-guidingcore, the flow-guiding core is expanded after absorbing ink to block the flow-limiting pipe, and the ink taking amount is controlled.

Description

technical field [0001] The invention relates to a watercolor pen, in particular to a watercolor pen which the user takes the ink actively. . Background technique [0002] The existing watercolor pen has the problems of small ink storage, uncontrollable ink output speed and short service life. Contents of the invention [0003] In order to overcome the shortcomings of the existing watercolor pens, the present invention provides a technology for the operator to take the ink actively and control the speed independently, so that the watercolor pens can have a better use effect. [0004] The technical scheme that the present invention uses is that a kind of internal ink-taking colored pen is made up of outer ink storage device, inner ink bag, ink-taking device, nib. An air passage is arranged on the outer ink storage device, and a breathable waterproof membrane is arranged in the air passage, and the upper and lower sections of the outer ink storage device are connected by th...
