Problems solved by technology

[0013] In summary, although the existing various types of direct liquid writing instruments can solve the shortcomings of some existing cotton core writing instruments, some of the above technical solutions use an air guide channel that is independent of the ink supply part, and some use an air guide channel that is independent of the ink supply part. Therefore, the balance between the ink and the air pressure cannot be accurately controlled, which makes the system undergo various complex and uncertain changes during the writing process, resulting in system failure. Instability and insufficient adaptability to ink

Embodiment 1

[0068] Specific reference figure 1 . A water-based marking pen, the surface tension of the ink is 30-35mN / m, the filling volume is 3.5g, and it is used for writing, marking and drawing. The ink absorber is made of polyester fiber cotton with a porosity of about 80%. The specific structure is as follows:

[0069] It includes: a pen body 4, which is used to hold ink and form the main body of a writing instrument; a writing element 1, which is installed on the head of the pen body; an ink absorption body 2, which is installed on the rear end of the writing element; a fiber water guide core 3, which Installed in the pen body, runs through the ink absorbing body, the front end is in contact with the writing element, and the rear end communicates with the ink tank formed in the inner cavity of the pen body; it is characterized in that, in the pen body, there is at least one A gas-liquid balancer 5, the gas-liquid balancer 5 is installed in the annular gap formed between the fiber ...

Embodiment 2

[0104] Embodiment 2: specific reference Figure 15 .

[0105] An alcohol-based permanent marker pen with an ink surface tension of 20-25mN / m and a filling volume of 3g for marking. The ink absorbing body adopts the design and realization of the similar structure of the gas-liquid balancer. Such as Figure 15 As shown, it includes: pen body 4, which is used to hold ink and form the main body of writing instrument; writing element 1, which is installed on the head of the pen body; ink absorbing body 2, which is installed on the rear end of writing element; fiber water guide core 3. It is installed in the pen body, runs through the ink absorbing body, the front end is in contact with the writing element, and the rear end communicates with the ink tank formed in the inner cavity of the pen body; it is characterized in that, in the pen body, a There is at least one gas-liquid balancer 5, and the gas-liquid balancer 5 is installed in the annular gap formed by the fiber water guid...

Embodiment 3

[0129] Embodiment 3: specific reference Figure 19 .

[0130] A capsule-changing water-based marking pen, the ink surface tension of which is 30-35mN / m, and the filling capacity of the ink capsule is 2.5g, is used for writing, marking and painting. Such as Figure 19As shown, the end fixing method of the fiber water diversion core and the structure of the pen body are changed. The pen body 4 adopts a split structure in which the ink bag is inserted together; the end of the fiber water diversion core is fixed by a separate ink bag fixing column, and the ink After the capsule is installed on the fixed column, the ink tank is formed; the rest of the structure is the same as that of Embodiment 2; of course, the gas-liquid balancer in this structure can also be selected Figure 5 , Figure 6 , Figure 7 structure shown.

[0131] In this structure, two gas-liquid balancers are used for step-by-step buffering. In addition, the front-end ink absorber 13 uses the same design struc...

Abstract

The invention discloses a direct liquid type writing tool. The tool comprises a pen body, a writing element, an ink absorbing body and a fiber water leading core. The pen body is used for containing ink and forming a main body of the writing tool, the writing element is arranged on the head of the pen body, the ink absorbing body is arranged at the rear end of the writing element, the fiber water leading core is arranged in the pen body and penetrates the ink absorbing body, the front end of the fiber water leading core makes contact with the writing element, the rear end of the fiber water leading core is communicated with an ink bin formed by a pen body inner cavity, at least one gas and liquid balancer is arranged in the pen body in the axis direction, and is arranged in an annular gap formed by the fiber water leading core and the pen body, one or multiple gas and liquid exchange grooves penetrating the outer circumference face of the gas and liquid balancer and having the capillary force effect on ink is arranged on the outer circumference face of the gas and liquid balancer, an overflow groove is formed in the radial face of the gas and liquid balancer, one end of the overflow groove makes contact with the fiber water leading core, and the other end of the overflow groove is communicated with the gas and liquid exchange groove, and the outer circumference face of the fiber water leading core and the inner hole wall of the gas and liquid balancer are in gapless fit or interference fit.

Description

technical field [0001] The invention relates to a direct-liquid writing implement. The direct-liquid writing implement refers to a writing implement in which ink is directly stored in a pen body in a liquid state. It can be used in stationery, medical or industrial fields. Liquid, and through a certain liquid outlet device to realize the writing, marking and coating device of the liquid, Background technique [0002] As a kind of writing tool, marker pens, especially marker pens using various solvent-based low surface tension inks, are widely used coated writing tools. Due to the low surface tension of ink, ink leakage and other problems are prone to occur, so marker pens The cotton core ink storage structure made of fiber is mainly used, but the cotton core ink storage structure will have ink residue, and the ink consumption will continue to decrease during the writing process, and the stability of the writing process is not enough. [0003] In order to solve the above pro...
