Abstract

The utility model relates to a fountain writing brush which has convenient use and dips ink according to the atmospheric pressure, comprising a hollow writing brush holder, a writing brush head sleeve (a writing brush cap) and a writing brush head. A catheter for feeding the ink is connected with the writing brush head. One end of the hollow writing brush holder of the utility model is provided with the writing brush head which can be conveniently replaced, and the other end is provided with an atmospheric pressure press button with a shrapnel cover. The ink in the hollow writing brush holder is sucked by pressing the atmospheric pressure press button, and the catheter is connected with the writing brush head. A flow control valve can continuously control the ink flow in the writing brush holder, thus causing the writing brush to have the characteristics of convenient water absorption and convenient water storage, and keeping the elegant advantage that a traditional writing brush has fluent writing.

Description

Fountain writing brush

The utility model relates to a kind of new-type writing implement, refers in particular to a kind of Writing brush with ink supply device of conveniently replaced nib.

Existing writing brush is generally made penholder by bamboo wood or bakelite material, the fixedly embedded pen hair in the end of penholder, because the no ink source of writing brush itself, need dip in China ink when writing, carry inconvenience, easy again pollution clothes, and also nib is short service life, have to abandoning pen is whole after nib is damaged, obviously is uneconomic.

The purpose of this utility model is to address the aforementioned drawbacks and provides a kind of and be convenient for carrying, and can change the Writing brush with ink supply device of nib according to writing different needs. and make the sort of suction water storage of the existing pen of writing brush characteristics easily, keep the elegance of traditional brush writing smoothness again.

The utility model is realized by following measure: by hollow penholder, pen point casing (cap for brush). nib is formed, conduit by ink delivery is connected with nib, improvement of the present utility model is that an end of hollow penholder is provided with conveniently replaced nib, the other end is provided with the air pressure knob of band aperture and shell fragment lid, ink in the hollow penholder is by sucking by giving as security the air pressure button, and conduit is connected with nib, but ink flowrate in the flow control valve continuous control penholder.

The utility model can also further be realized by following measure: the inwall of described flow control valve and hollow penholder is a threaded engagement, regulating this control valve continuously can join with the protrusion at the fan-shaped delivery port of penholder inwall place, and described replaceable nib is threaded with penholder.

Embodiment further specifies below in conjunction with accompanying drawing:

Fig. 1 is an installation diagram of the present utility model

Fig. 2 is the piston profile in the utility model

Fig. 3 is the piston upward view in the utility model

Fountain brush pen 9 among Fig. 1 is hollow penholders, the 10th, pen point casing (cap for brush), the 11st, the conduit of ink delivery, the 8th, the piston in the pick trough, the 6th, the air pressure button, the 7th, cover the shell fragment (lid) on air pressure button 6 pores, the 2nd, the ink flowrate control valve, the 3rd, be provided with the protrusion of being with scallop hole in the penholder inner chamber, the 4th, spring, the 5th, the moccasin chamber, an end of hollow penholder 9 is provided with conveniently replaced nib 1, and the other end is provided with the air pressure button 6 of band shell fragment 7, ink in the hollow penholder 9 is by sucking by giving as security air pressure button 6, conduit 10 is connected with nib 1, but ink flowrate in the flow control valve 2 continuous control penholders, and described flow control valve 2 is a threaded engagement with the inwall of hollow penholder 9, regulating continuously its protrusion of this control valve can join with its protrusion place of fan-shaped delivery port of establishing in the penholder inner chamber, for easy to process, penholder 9 can be an integral body, and the protrusion of the band scallop hole in its inner chamber can form by a casting.

Fig. 2 and Fig. 3 are respectively the profile and the upward views of piston, its operation principle is: when needs blot, earlier press the air pressure button with hand, because this button is provided with a spilehole and shell fragment lid 7 thereof, be release conditions this moment, and since the pick trough of the effect penholder lower end of air pressure stopped up by its piston, ink is unlikely to hold leakage. when openhanded when driving the air pressure button, its spring will restore to the original state, again since at this moment external atmospheric pressure greater than the air pressure in the chamber, spilehole on the button and shell fragment cover 7 auto-closings, move after piston in the pick trough is oppressed, ink is poured in the chamber by pick trough. when stopping blotting, because the gravity of ink impels piston to block pick trough again in the chamber.

Materials such as penholder can adopt metal. and bakelite or plastics are made, and the spring 4 that joins with button can adopt heat seal or gluing method to be connected with moccasin chamber 5.
