Detailed Description

The invention is further described below with reference to the figures and examples.

In this embodiment, the self-priming liquid type circulation ink storage environmental protection pen based on capillary and siphon effects comprises a pen holder and a pen point, wherein the pen holder and the pen point are detachably connected. The pen holder comprises a pen holder shell 1, a capillary liquid absorbing core 2, a ink sac tube 3 and a siphon tube 4, wherein the ink sac tube is positioned in the pen holder shell, the capillary liquid absorbing core is filled between the pen holder shell and the ink sac tube, the siphon tube is positioned in the rear end of the pen holder shell, the front end of the capillary liquid absorbing core is positioned at the front end of the pen holder shell, the rear end of the capillary liquid absorbing core is connected with the high liquid level end of the siphon tube, and the low liquid level end of the siphon tube is connected with the rear end of the ink sac tube.

In this embodiment, the capillary wick is a bundle of capillaries, although in various embodiments the capillary wick can be a porous capillary structure.

This embodiment is based on capillary and siphon effect from inhaling environmental protection pen of circulating storing up ink of liquid formula, when inhaling the ink, pull down the nib, insert the ink bottle with the front end of penholder, the ink rises in can following the capillary imbibition core in the penholder because capillary effect, when the ink rises to capillary core top, can trigger siphon effect emergence condition, and the ink can be because siphon effect is leading-in to the ink sac, realizes storing up ink. After the ink absorption is finished, the pen head part and the pen rod part are screwed for use.

The self-suction type circulating ink storage environment-friendly pen based on the capillary action and the siphon action realizes automatic ink transfer into the ink bag tube by utilizing the capillary action and the siphon action, is convenient to inject ink, can better control the ink injection amount, and solves the technical problem that the existing circulating ink injection gel ink pen needs manual ink injection.

As a modification of the above embodiment, the pen head of the self-priming liquid circulation ink storage environmental protection pen based on capillary and siphon effects comprises a pen head shell 5, an ink regulator 6, a pen point 7 and a water diversion fiber 8. The front ends of the pen head shell and the pen holder shell are connected through threads, and the pen head shell and the pen holder shell are convenient to disassemble and assemble. The ink regulator is arranged in the pen head shell, the pen point is arranged at the lower end of the ink regulator, the water diversion fiber is arranged in the ink regulator, the lower end of the water diversion fiber is positioned in the pen point, and the upper end of the water diversion fiber is positioned in the lower end of the ink bag pipe. The pen point 7 comprises a pen point body 71 and a ball 72 arranged at the front end of the pen point body, and a water-drawing fiber connecting hole is formed in the pen point body.

This improvement is based on capillary and siphon effect from inhaling liquid formula circulation and store up ink environmental protection pen, it adopts the water-drawing fibre to introduce the nib with the ink, and the nib adopts the ball to shift the ink to the paper on, the nib of having avoided the pen nib to exist is too hard and the problem of the paper of lacerating easily to and make nib play black clearance increase easily when having solved the pen nib atress, lead to going out the china ink too much and make dirty paper face's technical problem.

As a modification to the above embodiment, a ball valve 9 is arranged in the lower end of the ink bag tube, and the ball valve 9 comprises a metal ball 91 capable of moving up and down in the ink bag tube and a limiting seat 92 arranged on the inner wall of the ink bag tube for limiting the upward movement distance of the metal ball; the lower end of the ink bag tube is provided with an ink outlet hole which is in sliding fit with the water diversion fiber. When writing, the nib atress can upwards move a bit distance, and this distance is with not influencing the hand feeling of writing when the design and is accurate, and the nib shifts up and then drives the diversion fibre and move upward, and the diversion fibre moves upward with ball valve jack-up, and the ink can flow out from the ink outlet and follow the diversion fibre and get into the ink regulator to guarantee that the ink can be more reliable when writing in succession to the nib supply with in succession stable continuous for a long time. When the pen is not used for writing, the pen point moves forwards, and the metal ball is blocked on the ink outlet hole again, so that the ink is prevented from flowing out. In specific implementation, the limiting seat can be made of elastic rubber, or a spring is arranged between the limiting seat and the metal ball, and when the ball valve is not used for writing, the ball valve can be more reliably blocked by applying elastic force to the ball valve.

The lower extreme of penholder shell still is provided with stopper 10, the lower extreme top of ink sac pipe is on the stopper, sets up stopper 10 and enables the mounting structure of ink sac pipe more reliable. And a structure for the lower end of the capillary liquid absorbing core to penetrate through is arranged on the limiting block or between the limiting block and the pen holder shell, the structure can be a hole, a chamfered edge or a notch and the like, the lower end of the capillary liquid absorbing core downwards exceeds the limiting block or is flush with the lower end face of the limiting block, so that when the pen holder is inserted into an ink bottle to absorb ink, the ink can be sucked out under the condition that the ink in the ink bottle is little, and the ink waste can be avoided.

As an improvement to the above embodiment, the fins 11 for storing ink are distributed around the ink regulator, and the arrangement of the fins enables the ink regulator to store more ink, thereby better ensuring the continuity of writing.

As a modification of the above embodiment, the self-priming liquid circulation ink storage environmental protection pen based on capillary and siphon effects further comprises a pen cap 12 matched with the pen head. In this embodiment, the cap 12 includes a cap cover 121, a silicone pad 122 disposed at the top end of the cap cover for protecting the pen tip, and a pen clip 123 disposed on the cap cover, and the cap cover can protect the pen tip.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
