Abstract
The utility model relates to a dustless writing pen which comprises a penholder and a pen head. The utility model is characterized in that the inner part of the penholder is provided with a liquid storage inner cavity, an upper end board is provided with a liquid adding inlet, a lower end board is provided with a liquid outlet and a spring piston assembly, and the pen head is composed of a head cover, a word liquid adsorbing body which is arranged in a head cover body and a telescopic pen core which is penetrated inside. One end of the telescopic pen core penetrates through a supporting through hole of a front wall board of the head cover, and the other end is arranged in a groove which penetrates through the lower side part of a piston of the liquid outlet. The inner edge part of the supporting through hole is provided with a plurality of liquid seepage thin passages which are wound around the circumambience of the telescopic pen core. The utility model is favorable for a user to frequently add writing liquid for long-term use. Consequently, the dustless writing pen saves expense.
Description
The utility model relates to a kind of dust-free writing pen.
Existing a kind of dust-free writing pen in order to be used with blank mainly is implemented in writing on the blank by the pen core that is adsorbed with word liquid.In case its shortcoming mainly is a word liquid to be used up or dry, this lettering pen has had no value for use just discardable.So not only cause the waste but also the living environment that will contaminate society.
The purpose of this utility model is that a kind of dust-free writing pen will be provided, and it helps frequent interpolation of user and writes liquid, the long-term use, thus reduce expenses.
The utility model is to constitute like this, and it comprises penholder and be located at the nib of penholder bottom, it is characterized in that: 1) be provided with the liquid storage inner chamber in the penholder, its upper head plate has the liquid feeding inlet, and bottom plate central authorities are provided with liquid outlet and spring piston assembly.2) nib is by head-shield, the telescopic pen core of being located at the word liquid adsorbent in the head-shield body and being arranged in is wherein formed, one end of telescopic pen core passes the supporting through hole of head-shield front panel, the other end places in the groove of the piston underside portion of passing liquid outlet, offers several on the inner edge portion of described supporting through hole and is set around the telescopic pen core thin road of sepage on every side.
When holding penholder, the user on the plate face, writes, telescopic pen core pressurized and when upwards backing down piston, word liquid in the liquid storage inner chamber flows to word liquid adsorbent through liquid outlet under the effect of deadweight, in this simultaneously, word liquid in the head-shield inner chamber just flows out from the thin road of sepage and is covered with the telescopic pen core lower surface, so that write.
Word liquid in containing liquid penholder body is used up, and the user can add word liquid through the liquid feeding inlet of penholder, uses so that continue.Thereby avoided abandoning penholder, the phenomenon generation that causes waste and pollute.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the embodiment organigram.
With reference to Fig. 1, the utility model comprises penholder 1 and is located at the nib 2 of penholder bottom, it is characterized in that: 1) be provided with liquid storage inner chamber 3 in the penholder, its upper head plate has liquid feeding inlet 4, and bottom plate central authorities are provided with liquid outlet 5 and spring piston assembly.2) nib is by head-shield 6, the telescopic pen core 8 of being located at the word liquid adsorbent 7 in the head-shield body and being arranged in is wherein formed, one end of telescopic pen core passes the supporting through hole 9 of head-shield front panel, the other end places in the groove of the piston underside portion of passing liquid outlet 5, offers several on the inner edge portion of described supporting through hole and is set around the telescopic pen core thin road 10 of sepage on every side.
Above-mentioned spring piston assembly is inserted in the interior other end of piston upside groove by piston 11, one ends that cover liquid outlet and passes the perpendicular pin 14 of support 12 support holes 13 and be placed in perpendicular pin periphery and 15 formations of the stage clip between piston and bracket supports hole.
In order to prevent that word liquid from leaking, the liquid feeding inlet 4 of penholder upper head plate is the liquid feeding screw, and the liquid feeding screw is provided with screw rod plug 16, and screw rod is arranged with the sealing gasket 19 between its back shroud 17 and penholder upper head plate 18 beyond the Great Wall.
For preservation and the use that helps the dust-free writing pen, be socketed with the cap for brush 20 on the outer edge of head-shield, outer rim 21 diameters of penholder upper end and inner edge 22 equal diameters (so that socket-connecting) of cap for brush socket part, and greater than the diameter of screw rod plug back shroud 17 (purpose is to avoid the cap for brush to touch the screw rod plug in socket or when breaking away from penholder top, thereby causes seepage).
During use, the user should unplug the cap for brush earlier, and the cap for brush is buckled on the outer rim of penholder upper end, then, hold penholder and on the plate face, write, make the telescopic pen core pressurized and upwards back down piston (at this moment, perpendicular pin is up, stage clip shrinks), so the word liquid in the liquid storage inner chamber just flows down through liquid outlet under the effect of deadweight, simultaneously, force word liquid in the head-shield inner chamber also constantly to flow out and be covered with the telescopic pen core lower surface, so that write from the thin road of sepage.Write and finish, piston resets under the effect of the elastic restoring force of stage clip and covers liquid outlet, and simultaneously, telescopic pen core also descends horizontal reset.End user extracts the cap for brush on the outer rim of penholder upper end out and covers on the nib.
Word liquid in containing liquid penholder body is used up, and user's screw rod plug of can outwarding winding adds word liquid through the liquid feeding inlet of penholder, uses so that continue.
The utility model is reasonable in design, and is economic and practical, and its market prospects are considerable.
