Abstract
The invention relates to an environment-friendly dustless chalk, in particular to an environment-friendly dustless chalk which is suitable to be used for teaching. The environment-friendly dustless chalk comprises a penholder, a pen point and a pen head, wherein the penholder is connected with the pen point; and the pen head is arranged on the pen point. The environment-friendly dustless chalk has the structural characteristics that: a valve cover and a valve body are fixed on the pen point; a valve needle, a valve ring, a spring and a retaining bead are arranged inside the valve body; the upper part of the valve needle is connected with the pen head; the valve cover and the valve needle seal the upper part of the valve body together; the lower part of the valve needle is connected with the retaining bead through the spring; a water inlet is arranged on the valve needle; the valve ring is arranged between the valve needle and the valve body; and the valve ring is matched with the water inlet. The environment-friendly dustless chalk has the advantages of reasonable structural design, capability of yielding water in all directions, automatic water supply of the pen head, and convenient use.
Description
Technical field
The present invention relates to a kind of liquid dustless chalk, particularly a kind of liquid dustless chalk that is adapted at imparting knowledge to students and uses.
Background technology
Existing blackboard pen can not comprehensive water outlet when writing, and after writing a break time, must firmly press nib downwards, just can water outlet, and use is very inconvenient, can interrupt teacher's teaching thinking, can not be with getting with writing as traditional chalk.
Summary of the invention
Technical problem to be solved by this invention provides a kind of reasonable in design, the comprehensive water outlet of energy 360 degree, written automatic water-supply, liquid dustless chalk easy to use.
It is this liquid dustless chalk that the present invention solves the problems of the technologies described above the technical scheme that is adopted, comprise penholder, nib and nib, penholder links to each other with nib, nib is arranged on the nib, its design feature is: be set with valve gap and valve body on the described nib, be provided with needle, valve circle, spring and block bead in the valve body, the top of needle links to each other with nib, valve gap and needle are jointly with the top seal of valve body, the bottom of needle links to each other by spring with block bead, needle is provided with water inlet, and the valve circle is arranged between needle and the valve body, and valve circle and water inlet are complementary.
Penholder of the present invention and nib are threaded.Can keep certain tightness because be threaded, and dismounting easily, convenient perfusion ink.
The end of penholder of the present invention be provided with active ring, after seal, mix pearl and bonnet, back envelope is embedded in the penholder, bonnet Gai Zaihou seals up, active ring is arranged in the penholder, the shape of its shape and penholder is complementary, and links to each other by rope between active ring and bonnet, mixes pearl and is arranged in the penholder.The dandle penholder is mixed pearl ink is fully mixed in use.
The present invention compares with prior art and has the following advantages and effect: 1, the liquid dustless chalk of the present invention for writing to any direction, as long as the nib of pressing, ink can be supplied immediately.2, owing to be provided with valve body, needle and other supporting with it parts, can in the process of using, blot automatically, reasonable in design, exquisite.3, owing to be provided with active ring, make the inner space of whole penholder can hold ink, increased the memory space of ink greatly, more convenient to use.4, owing to be provided with sponge, the ink feed of nib is quicker, sufficient, has further guaranteed the smoothness of writing.
Description of drawings
Fig. 1 does not have the structural representation of the cap for brush for the present invention.
Fig. 2 is another structural representation of the present invention.
Fig. 3 is the partial enlarged drawing of Fig. 1.
Fig. 4 is the partial enlarged drawing of Fig. 2.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment, and following examples are explanation of the invention and the present invention is not limited to following examples.
Embodiment 1:
Shown in Fig. 1 to 4, present embodiment by penholder 5, nib 4, nib 2, sponge 3, valve body 11, needle 8, valve gap 9, valve circle 10, spring 12, block bead 13, mix pearl 14, back envelope 7, active ring 6, bonnet 15, rope 18 and the cap for brush 1 and form.
Back envelope 7, penholder 5 are connected successively with nib 4, and wherein back envelope 7 is stuck in the penholder 5, and nib 4 is connected with penholder 5 by screw thread.Valve body 11 and valve gap 9 are fixedly installed on the nib 4.Sponge 3 is fixed on the valve gap 9, and needle 8 is arranged in the valve body 11, and an end of needle 8 links to each other needle 8 and sponge 3 together support nibs 2 with nib 2.The other end of needle 8 is connected with spring 12, and spring 12 links to each other with block bead 13, and block bead 13 retainings are at the end opening place of valve body 11.Needle 8 is provided with water inlet 16, is provided with valve circle 10 in the position of water inlet 16, and valve circle 10 is stuck between needle 8 and the valve body 11, and valve circle 10 blocks water inlet 16.
Back envelope 7 is provided with bonnet 15, is connected with rope 18 on the bonnet 15, and the other end of rope 18 links to each other with active ring 6, and active ring 6 is arranged in the penholder 5, and the shape of active ring 6 matches with the internal diameter of penholder 5.Mix pearl 14 and be provided with in the penholder 5, fluctuate before the use, mixing pearl 14 will stir ink.The cap for brush 1 is arranged on the nib 4.
During use, press nib and make after 2 needle 8 drive valve circles 10 to move down, spring 12 is compressed simultaneously, makes block bead 13 and valve body 11 closures.When valve circle 10 moves down into to a certain degree, by withstanding in the valve body 11, at this moment, needle 8 relative valve circles 10 move downward, make that water inlet 16 is open, ink in the valve body 11 enters needle 8 by the water inlet 16 between needle 8 and the valve circle 10 under pressure, thereby enters Sponge 3 and nib 2, has finished written suction.
Decontrol nib 2, spring 12 returns, valve circle 10 and needle 8 are closed and moves upward simultaneously under the effect of spring 12, produce negative pressure in valve body 11, make the space of ink by 11 of block bead 13 and valve bodies in the penholder 5 enter valve body 11.Because the ink in the penholder 5 is siphoned away by valve body 11, active ring 6 also can move up under negative pressure.
Constantly suction in valve body 11 like this in the writing process of nib, valve body 11 constantly absorbs water in penholder 5, has finished the automatically additional ink of nib, and nib can be pushed the side by 360 degree entirely, do not need specific angle, just can produce enough negative pressure and absorb water.
After ink used up, the penholder 5 of outwarding winding was opened bonnet 15, with rope active ring 6 is left behind, and covers bonnet 15, replenished ink then in penholder 5, recycled.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of patent of the present invention according to patent of the present invention.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present invention or surmount the defined scope of these claims, all should belong to protection scope of the present invention.
