Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the realization of concrete accompanying drawing to the present embodiment.
As shown in Figures 2 to 4, control liquid pressing structure, comprise the body 13 being arranged on liquid storing part 14 port, body 13 inside is provided with the liquid guiding cavity 132 being communicated to liquid storing part 14 inner chamber, and body 13 front end is provided with control liquid part 131, offers delivery hole in the middle part of control liquid part 131, delivery hole is equipped with telescopic nib 11, delivery hole madial wall is provided with the capillary structure of multiple indent, and capillary structure coordinates nib 11 lateral surface to be combined to form multiple capillary group 1311, and liquid guiding cavity 132 is communicated to the external world by capillary group.
When pressing nib 11, nib 11 rear portion is soaked and is oppressed liquid in liquid guiding cavity 132, make its pressure increase, the capillary group 1311 forcing liquid be formed outside capillary structure and nib 11 flows out, direct confession nib 11 adsorbs or flows into exterior chamber storage, for nib 11 indirect attachment, can write for nib 11.
Control liquid pressing structure in the present embodiment, because liquid guiding cavity 13 relies on capillary group 1311 output liquid, and non-immediate flows out, that fluid flow greatly reduces, easy control, can according to the moistening degree of actual nib, or the degree of saturation of exterior chamber judges whether to continue pressing, avoid occurring that compression number cannot be held and the situation causing liquid too much to exosmose, if exterior chamber is saturated, hydro-cushion between exterior chamber and liquid guiding cavity 132, liquid is difficult to be shifted by capillary group 1311, it also avoid the problem that too much liquid causes exosmosing.
As shown in Figure 2, body 13 extends into liquid storing part 14 inner chamber for tubular structure its rear end, and sidewall is offered the breach be directly communicated with, be convenient to liquid and enter, the cavity of tubular structure inside is liquid guiding cavity 132.
Offer in the rear end of body 13 and the pilot hole of nib 11 coaxial line (in figure, direction does not directly illustrate), in pilot hole, be equipped with guide post 133.Guide post 133 front end is connected to the rear end of nib 11, middle part is provided with fixture block 1331, back-moving spring (not shown) is provided with between fixture block 1331 and body 13 rear inside wall, back-moving spring is set in guide post 133 rear portion, and two ends are connected to fixture block 1331 and body 13 rear inside wall respectively.When nib 11 is pressed retraction, in the restriction direction slippage of guide post 133, can not deflect bending, back-moving spring is compressed simultaneously, after extraneous pressing force disappears, and back-moving spring release elastic potential energy, make nib 11 homing, be convenient to carry out written indicia or pressing next time.
Fixture block 1331 is conical as shown in Figure 2, space, towards nib 11, is left between other end outer wall and liquid guiding cavity 132 inwall in its tip, when fixture block 1331 moves, conical design is convenient to oppress liquid and is entered the tip of fixture block 1331 along aforesaid space, and is driven and enters capillary group 1311.
The present embodiment additionally provides control liquid pen 1, comprise aforesaid control liquid pressing structure, nib 12 and penholder 14, its integral installation structure as shown in Figure 2, penholder 14 is liquid storing part 14, the body 13 of control liquid pressing structure is installed between the end of penholder 14 and nib 12, nib 11 through nib 12, and extends to its front end.
Control liquid pen 1 in the present embodiment, by controlling the amount of liquid that liquid pressing structure controls to flow out to from penholder 14 in nib 12, can avoid repeatedly pressing and causing trickle too much, polluting the problem at written indicia position.
Penholder 14 inside forms the liquid storage cylinder that can store liquid, and nib 12 is inner forms the exterior chamber that can store from liquid guiding cavity 132 liquid body exudate, is nib 11 directly feed flow.Form hydro-cushion by capillary group 1311 between exterior chamber and liquid guiding cavity 132, after it is saturated, capillary group 1311 can be hindered to continue the liquid that exosmoses, avoid too much excessive.
As shown in Figure 2, written 12 inner ring are arranged with can the tank body 121 of storage of liquids, and nib 11 is inner and be close to it through tank body 121.Tank body 121 adopts porous adsorbing material, and such as sponge, active carbon, other macromolecular materials etc. are made, can adsorption storage partially liq, nib 11 is close to it, ink storage body 121 moisten under, namely there will not be the situation of exsiccation, it also avoid too moistening, nib takes excess liq out of.
The rear end face of tank body 121 is connected to control liquid part 131, nib 12 madial walls are provided with the first liquid storage cylinder 122, first liquid storage cylinder 122 is with the sections inner side wall of nib 12 for the first side wall, and its second sidewall 1221 one end is connected to written 12 madial walls, and the other end presses on tank body 121 front end face.
After tank body 121 is saturated, because the second sidewall 1221 is pressed on tank body 121 front end, make it deform, unnecessary liquid can enter in the first liquid storage cylinder 122, temporary transient storage, when in writing process liquid-consumed larger time, the liquid in the tank body 121 directly contacted with nib 11 is first consumed totally, then the liquid in the first liquid storage cylinder 122 is absorbed by tank body 121 again, is nib 11 feed flow.This first liquid storage cylinder 122 coordinates the mode of tank body 121, both ensure that the capacity of liquid guiding cavity 13, decreases inner free fluid simultaneously, avoids these free fluids and overflows.
As shown in Figure 2 and Figure 4, the front end of nib 12 is punctured into conus portion 123, it is most advanced and sophisticated that nib 11 is assemblied in conus portion 123, conus portion 123 madial wall and the first side wall, second sidewall 1221 one end is positioned at conus portion 123 madial wall, and the other end presses on tank body 121, the madial wall that itself and conus portion 123 bend forms the first liquid storage cylinder 122, the open rearward end of the first liquid storage cylinder 122, this opening is closed by tank body 121, by this opening exchanging liquid between tank body 121 and the first liquid storage cylinder 122.
As shown in Figure 2 and Figure 4, continue to extend to nib cylinder 124 at conus portion 123 tip, the second liquid storage cylinder 1241 is provided with in nib cylinder 124, nib 11 assembles interior with nib cylinder 124 and passes nib cylinder 124, nib 11 is provided with and carrying of liquids can enters the ring-type breach 111 of the second liquid storage cylinder 1241, nib 11 back and forth pressed through written 12 time, ring-type breach 111 can carry a small amount of liquid and enter the second liquid storage cylinder 1241, store a small amount of liquid, the meaning of the second liquid storage cylinder 1241 is direct feed flow, buffering liquid exosmoses and increase the capacity of actual nib 12.
Control liquid pen 1 in the present embodiment, in use, two liquid storage cylinders and ink storage body 121 cooperatively interact, and are nib 11 feed flow, make it become dry.Long-term when not using, nib 11 becomes dry, two liquid storage cylinders and ink storage body 121 also vacant, only need press nib 11, liquid is exosmosed by capillary group 1311, then enters two liquid storage cylinders and ink storage body 121 makes it saturated, is nib 11 feed flow.Repeatedly after pressing, due to inside and outside hydro-cushion, exterior chamber is saturated, and liquid cannot continue through capillary group 1311, thus avoids repeatedly pressing and cause intravenous extravasation, pollutes the problem at written indicia position.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
