Description

Gel pen

Technical Field

The utility model relates to a pen, in particular to a pen for industrial or children entertainment.

Background

There is a kind of adhesive cement on the market, after it is coated on the surface of paper or object, it is heated by electrothermal blowing or heating equipment, and the coated slurry will foam and bulge to generate different concave-convex feeling. Because of the high viscosity of this cement, it has no way to flow by natural air pressure alone. That is, it is not feasible as it would be with a conventional water-based pen or a Mark pen. At present, in order to generate the foaming effect on paper or articles in the market, a silk screen printing mode is adopted to adhere the mucilage to the paper or the articles, and then the mucilage is heated. The imaging mode is too complex, and for some simple writing, the imaging mode is too complex to complete, i.e. create. However, it is also conceivable to write by means of a glue gun or to put the glue into a sealed soft body and to let the glue flow out by manual squeezing.

There is no writing instrument available on the market that can be used with a paste like a conventional pen.

According to the scheme, the nib is pressed in an artificial book mode to control the needle valve to be opened or closed, and the pressure brought by the slurry pushing device is combined to realize that the thick high-viscosity mucilage is written in the industry or is blank. The implementation of the slurry pushing device is not particularly required in the scheme, and besides manual operation, the independent slurry pushing device combined with the nib needle valve can realize writing.

The technical scheme is further refined, and the slurry pushing device comprises a piston and a piston power supply device; the piston is connected with a piston power supply device, and the piston power supply device pushes the piston to move. The piston may be a general piston or a follow-up sealing agent. The piston power supply device can be manually provided, such as manual pressure like a glue gun, pneumatic pressure or screw pushing mode of a motor; of course, the pneumatic pump is adopted to provide pressure more reasonably, economically and conveniently. This similar pressure pattern can be used as a pressure source.

The pneumatic pressure source is adopted to provide pressure for the pen, firstly, the pressure required by the pen is not high, when the air pump is started, the pen point is manually pressed, the needle valve is opened, and under the pressure of the air pump, the slurry flows to the pen point along the gap between the inner wall of the pen point and the needle valve, so that writing is completed. When the writer stops pressing, the needle valve is closed; at this time, even if the air pump works, the pressure of the air pump cannot push the piston, and the electric pump stops working after reaching the corresponding pressure.

The gas pressure of the electric pump is connected to the sealing element through the gas pipe, and the sealing element is used for forming a gas cavity between the sealing element and the piston, and the sealing means that a seal is formed between the circumference of the sealing element and the pen core. The piston is pushed forward by the air pressure until the needle valve is closed or the slurry in the pen core is conveyed completely. The utility model adopts the scheme that the main purpose is that under the scheme, when the piston moves and the sealing element does not move, the sealing element can be directly pulled out when the refill is replaced, the refill is thrown away together with the piston, and the other refill is replaced, and the refill is required to be replaced, and the refill is provided with the piston (the piston can be a sealing follower); or the pen plug is put into the pen core manually; and then the sealing element is put into the pen core.

The technical scheme is further refined, and the pen core is fixedly connected with the pen point through threaded connection or other modes; the top of the pen refill is provided with a convex connector; the pen point consists of a pen point shell, a pen point connecting seat, a pen point, a needle valve and a reset spring; the pen point shell is fixedly connected with the pen point connecting seat, is hollow, and the pen point connecting seat is connected with the convex connector at the top of the pen core through threads; the pen point is fixedly connected to the needle valve and the reset spring is arranged in the pen head shell, the pen point and the needle valve block the pen point to be connected with the reset spring, and the reset spring is fixed; after the nib is pressed, the needle valve is opened. The pen point is different from the pen point in the prior art in that the liquid flow in the pen core is controlled by adopting a mode of combining the pen point and the needle valve. Unlike the prior art, no valve control is required. The root cause of this is that the glue will not flow downwards under atmospheric pressure if there is a certain pressure in the cartridge, but will always flow outwards if there is such a pressure, if no valve control is used, as in the prior art glue guns. The utility model adopts the combination of pressure and valve to realize the free pressing after pressing and releasing. Meanwhile, the threaded connection between the pen point and the pen core is adopted, so that the pen point is prevented from falling off under the condition of pressure or pressing.
