Detailed description of the invention
As depicted in figs. 1 and 2, easy white board marker out of ink, primarily of penholder 1, the cap for brush 2, pen core 3 and ink composition, described penholder hollow, ink reservoir is in penholder endoporus, and one end of a body reduces and forms nib 4, and the other end is connected with the cap for brush.
As shown in Figure 2 and Figure 5, described white board marker easy to be out of ink also comprises ink-feeding tube 5, be placed in the inking device in the cap for brush and piston 6.
As shown in Figure 4, the axis along nib 4 is provided with pen core fixing hole, and pen core is fixed from inserting pen core fixing hole outside to inside; Pen core fixing hole is to the raised formation in the direction pen core fixed leg 41 of the cap for brush, described pen core fixed leg forms pen core stop bit bead 42 towards the edge of cap for brush one end to inner process, the diameter of bore of pen core stop bit bead is less than the diameter of pen core, pen core can not be moved up and block the port of export of ink-feeding tube; Ink-feeding tube 5 outwards expands formation ink storage chamber 51 towards the end face of nib one end, ink storage chamber 51 is connected in pen core fixed leg on the end face of cap for brush one end or in pen core stop bit bead away from the edge of ink-feeding tube 5, makes the ink in penholder can only enter the endoporus of pen core fixed leg from ink storage chamber.When ink enters ink storage chamber 51 by ink-feeding tube, as long as nib down, ink will flow to pen core fixed leg endoporus, soaks pen core.Because pen core normally adopts the material of easily water suction to make, ink can spread along pen core the pen core top arriving and be positioned at outside nib automatically, thus can write.Ink storage chamber adopts with between pen core fixed leg or pen core stop bit bead the mode be fixedly connected with, and ink can not be flowed back to from gap between the two in a body, to ensure that pen core can obtain sufficient ink feed.
As shown in Figure 3, ink-feeding tube 5 outwards expands towards the end face of the cap for brush one end piston cylinder 52 forming columnar hollow, be provided with near the inwall of the cap for brush bracing frame 11 being with centre bore at penholder 1, the piston cylinder 52 of ink-feeding tube is positioned at the centre bore of bracing frame 11, the wall of piston cylinder is provided with ink-feeding hole 521, and ink-feeding hole is connected with the endoporus of penholder; In the cap for brush 2, be also provided with fixed head 21, fixed head 21 is provided with the piston fixed leg 22 to cap for brush top boss, in piston fixed leg, is provided with the demarcation strip parallel with fixed head 21, demarcation strip is provided with piston fixing hole.
Be provided with pressing key 7 on the top of the cap for brush, described pressing key can move forward and backward along the endoporus of the cap for brush under the effect of external force; Piston 6 enters piston cylinder from cap for brush one end, is formed closely cooperate with piston cylinder inwall; Piston rod 61 passes the piston fixing hole demarcation strip from body one end, then through spring 8, end is fixed on pressing key 7 inwall; Described spring 8 one end pushes against the inwall of pressing key, and the other end enters piston fixed leg 22 and pushes against demarcation strip; When not pressing pressing key 7, piston 6 moves up and enters piston fixed leg 22 towards in the endoporus of nib under the tension force effect of spring 8.
When needing ink supply, first allow nib upward, the ink in a body is made to enter piston cylinder by ink-feeding hole, make again nib down or tilt down, after pressing pressing key, spring 8 is squeezed to the Direction distortion of nib, pressing key 7 moves to nib in piston cylinder to the direction promotion piston 6 of nib, ink in piston cylinder is clamp-oned ink-feeding tube 5, ink is made to arrive ink storage chamber 51 and pen core fixed leg endoporus, the pen core 3 being arranged in pen core fixed leg endoporus just can be drawn onto ink, realize the ink supply to pen core 3, at this moment, negative pressure is formed in penholder, extraneous air enters in the cap for brush by the space between pressing key and the cap for brush, piston cylinder is entered again by the space between piston rod and demarcation strip, and then enter a body by ink-feeding hole, air pressure is tended to balance, decontrol pressing key, under spring tension, pressing key and piston reset to the top of the cap for brush, negative pressure is formed in piston cylinder between piston and ink-feeding tube, partial air in body can enter in the piston cylinder between piston and ink-feeding tube by ink-feeding hole automatically, negative pressure is reduced.In the reset state, in the piston cylinder of piston between ink-feeding hole and pressing key, ink-feeding hole can not be blocked.
When piston is between ink-feeding hole and pressing key, as long as by nib upward, the ink in penholder will flow in piston cylinder by ink-feeding hole, for ink supply is ready next time.
As shown in Figure 6 and Figure 7, piston fixing hole is towards the edge of pressing key to the raised formation in the direction sealing column 23 of pressing key, at piston rod 61 and piston fixing hole inwall and the profile of tooth sealing ring 9 being provided with multilayer parallel tooth between piston rod and the inwall of sealing column, the tooth of profile of tooth sealing ring tilts to the direction of ink-feeding tube from the cap for brush.In the process of piston reset, if have ink between piston and demarcation strip, can flow back in a body by ink-feeding hole, or flow in the piston cylinder between piston and ink-feeding tube by the space between piston and piston cylinder, owing to being provided with profile of tooth sealing ring 9, make ink can not in the cap for brush that the space of piston rod and demarcation strip flows to above demarcation strip people, the extraneous air of amount can fall tooth punching shape sealing ring 9 and enter in piston cylinder.
Sealing column 23 is provided with the locking cap 24 be threaded connection with it.
Described ink-feeding hole 521 is arranged on the wall of the piston cylinder 52 being positioned at a body of fixed head 21.
Described fixed head 21 is more than or equal to the height of piston towards the wall of nib one end and demarcation strip towards the distance of the wall of nib one end.
The diameter of bore of described ink-feeding tube is less than the aperture of piston cylinder and fills the aperture in black chamber.When forming negative pressure in piston cylinder, part ink in ink-feeding tube can flow backwards and get back in piston cylinder, due to ink-feeding tube more carefully and longer, the resorption power that the ink that negative pressure in piston cylinder is adjusted the distance in piston cylinder ink-feeding tube far away is formed will reduce, and, sectional area due to ink storage chamber is greater than the sectional area of ink-feeding tube, and the ink of ink storage chamber is not easily drawn back in piston cylinder.Because pen core has higher density and good solid water, the possibility that the ink in pen core is returned in piston cylinder by suck-back due to the negative pressure in piston cylinder is very low.Only under the promotion of piston, ink just can be made to be squeezed into ink storage chamber from piston cylinder, conversely, during piston reset, the ink in Chu Sai chamber is difficult to get back to piston cylinder by ink-feeding tube.When piston is motionless, white board marker inside forms a comparatively stable poised state, ink in piston cylinder is also difficult to flow to ink storage chamber by ink-feeding tube, thus ink storage chamber can be pen core supply ink constantly, only have when there is no ink in ink storage chamber, just need to press pressing key, by piston, ink is shifted onto ink storage chamber from plunger shaft, realize ink supply.
Fixing bead is outwardly provided with, for fixing support rack at the outer wall of piston cylinder; Piston cylinder is positioned on the center line of penholder endoporus, so that make piston enter piston cylinder during assembling.
