Abstract

The utility model discloses a marking pen which comprises a tubular pen body with two opening ends, a tail plug is arranged on an opening at one end, a valve is arranged on an opening at the other end, a refill is connected with the outlet of the valve, a sponge ring used for ink storage is sleeved on the outer edge of the joint of the valve and the refill, and the sponge ring is contained in the corresponding opening of the pen body. Due to the fact that the sponge ring is additionally arranged and sponge has a strong blotting function, when the valve is opened for the ink storage each time, ink gushes out of the valve to be absorbed by the sponge ring and then supplied to the refill in a continuous and balanced mode through the sponge ring. Therefore, the defect that ink supplying is unbalanced for a marking pen manufactured according to the prior art is overcome.

Description

A kind of marking pen

Technical field

The utility model relates to the pen technology field, more specifically says a kind of marking pen.

Background technology

Marking pen comprises white board marker, watercolor pencil etc., and more common in our daily life is white board marker, and it is a kind of instrument of writing on blank, is similar to the chalk of blackboard.This pen is to use printing ink as ink, can write on smooth white version, and available whiteboard eraser is wiped.

The marking pen structure that occurs on the market now such as patent ZL201020124531.9 record comprise pen core, the cap for brush, accommodate pen container and the tail plug of ink, are provided with in described pen container for the valve of controlling providing ink, and described valve export connects pen core.

There are following two defectives in the structure of existing marking pen: (1) providing ink is not smooth, although there is valve to control, valve is only a current limiting switch, and the effect that continues to hold China ink is not obvious; (2) valve is opened at every turn and is held China ink and a black phenomenon often can occur dripping, causes to write at the beginning and pastes over a glob ofly, is difficult to allow the people accept.

The utility model content

The purpose of this utility model is to overcome above defective, provides a kind of and is easy to realize, is convenient to make, continues to hold the balanced marking pen of China ink.

In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of marking pen comprises the pen container of both ends open tubular structure wherein being provided with the tail plug on an end opening, be provided with valve on other end opening, valve export is connected with a pen core; It is characterized in that, be arranged with a sponge ring that holds black use on the outer rim of described valve and pen core junction, sponge ring is contained in described pen container opening.

The utility model has increased sponge ring, sponge has stronger blotting effect, when holding China ink at every turn and open valve, ink is gushed out from valve and is adsorbed by sponge ring, continue to supply with less unbalanced defective when many when so having solved prior art marking pen structure ink balancedly to the pen core ink supply by sponge ring again.The utility model has only increased a sponge ring, has just reached beyond thought effect, and the sponge ring manufacturing is simple, installs additional also easily to realize on the marking pen original structure.

As preferably, described valve comprises spool, valve casing and spring, and spool is arranged in the core chamber of valve casing, and is being connected spring between spool and valve casing; Be provided with the opening that is conducted with the inner core chamber on the tail end end face of valve casing; The front end hollow of spool is provided with the passage of taking in pen core, is provided with the through hole that communicates with the outside on channel side wall; Be provided with the flange that one section described opening of isolation communicates with described passage on the middle part of spool; Sponge ring is sheathed on the outer rim of spool and pen core junction.

Valve belongs to more conventional structure, needs to do slight improvement after being applied on marking pen, and passage namely is set in spool, and passage is staged so that accommodate pen core.

As preferably, pen container is arranged with the cap for brush in pen core end outer rim.

Marking pen is different from other pens, and its pen core speckles with ink, will write out so encounter, and therefore in order to prevent the waste of improper practicality, must set up a cap for brush and be protected.

Beneficial effect: the utility model has increased sponge ring, sponge has stronger blotting effect, when holding China ink at every turn and open valve, ink is gushed out from valve and is adsorbed by sponge ring, continue to supply with less unbalanced defective when many when so having solved prior art marking pen structure ink balancedly to the pen core ink supply by sponge ring again.

The specific embodiment

Be easy to understand understanding in order to make technological means of the present utility model, creation characteristic and to reach purpose, further set forth the utility model below in conjunction with specific embodiment.

Embodiment: as shown in Figure 1, a kind of marking pen comprises the pen container 1 of both ends open tubular structure wherein being provided with tail plug 2 on an end opening that be provided with valve on other end opening, valve export is connected with a pen core 3; Pen container 1 is arranged with the cap for brush 8 in pen core 3 end outer rims.

Valve comprises spool 5, valve casing 4 and spring 6, and spool 5 is arranged in the core chamber 9 of valve casing 4, and is being connected spring 6 between spool 5 and valve casing 4; Be provided with the opening 10 that is conducted with inner core chamber 9 on the tail end end face of valve casing 4; The front end hollow of spool 5 is provided with the passage 11 of taking in pen core 3, is provided with the through hole 12 that communicates with the outside on passage 11 sidewalls; Be provided with the flange 13 that one section isolation opening 10 communicates with passage 11 on the middle part of spool 5.

Be arranged with a sponge ring 7 that holds black use on the outer rim of spool 5 and pen core 3 junctions, sponge ring 7 is contained in described pen container 1 opening.

Practical: the utility model has increased sponge ring, sponge has stronger blotting effect, when holding China ink at every turn and open valve, ink is gushed out from valve and is adsorbed by sponge ring, continue to supply with less unbalanced defective when many when so having solved prior art marking pen structure ink balancedly to the pen core ink supply by sponge ring again.

Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
