Description
Technical field
The present invention relates to the ball pen liquid-adding device, especially a kind of liquid-adding device of refill for ball-point pen.
Background technology
Ball pen has become the current consumption product of ordinary populace as a kind of writing implement.Many people writing after liquid uses up in pen core, cheap because of it, especially the price of the retail price of pen core and whole pen is very nearly the same on terminal market, thereby select ball pen is arbitrarily abandoned as the one-time consumption product, make it become house refuse, this has just caused the significant wastage of social resources.Trace sth. to its source and be: existing pen core is to produce in batches at the special equipment of a system company, the operation that liquid is write in perfusion is to be finished by the machine of complexity, therefore, as the terminal consumer, writing after liquid uses up in pen core, can't write liquid to injection in the pen core, can only very reluctantly ball pen be abandoned.
Summary of the invention
The objective of the invention is to: provide a kind of refill for ball-point pen simple in structure, with low cost self-service liquid-adding device, single manual operations just can realize injecting in pen core writes liquid, not only can prolong the service life of nib to greatest extent, and can change the nib of wearing and tearing, recycle core bar, make pen core regeneration, thereby reduce use cost, save social resources, low-carbon environment-friendly.
For achieving the above object, the present invention can take following technical proposals:
The self-service liquid-adding device of a kind of refill for ball-point pen of the present invention, comprise that is used for the container that the splendid attire ball pen is write liquid, described container has the container chamber device for exerting, top at this container is provided with liquid outlet, described liquid outlet is provided with sealing ring, when the ball pen core bar inserted container from described liquid outlet, the outer wall of described ball pen core bar and the inwall of sealing ring constituted hermetic seal.
The chamber wall of described container is made by elastomeric material, and described container chamber device for exerting is made of container itself.
The top of described container also is provided with the pressurization mouth, and described container chamber device for exerting is the air bag that is connected on the pressurization mouth.
The upper end of described air bag is provided with breather check valve, the lower end of air bag is provided with exhaust check valve, described breather check valve comprises the lightweight ball that is arranged in the inlet channel chamber, the top in inlet channel chamber is that a diameter is less than the through hole of lightweight bulb diameter, the dead in line in described through hole and inlet channel chamber, the bottom in inlet channel chamber be at least one diameter less than the small through hole of lightweight bulb diameter, the axis of each described small through hole all departs from the axis in inlet channel chamber; The structure of described exhaust check valve is identical with the structure of breather check valve.
The top of described container also is provided with the pressurization mouth, and described container chamber device for exerting comprises that sealing is arranged at the piston cylinder on the pressurization mouth, is arranged at the piston head in this piston cylinder, and the upper end of described piston head is connected with piston rod.
