The wall thickness of the pen tube 1 is reduced from top to bottom. The remainder was the same as in example 1.
The structure of the vacuum pressing device is specifically analyzed as follows:
regarding the inner cylinder 6: the inner barrel 6 is fixed at the inner top of the pen tube 1, and the position of the inner barrel is not changed along with the pressing action. Because the outer wall of the inner cylinder body 6 is attached and fixed with the inner wall of the pen container, the spaces at the upper end and the lower end of the inner cylinder body 6 are not communicated in practice and are separated by the inner cylinder body 6. The center of the bottom of the inner cylinder 6 is provided with a through hole, and the through hole is provided with a lower closing cap 13, so that when the lower closing cap 13 is opened, the spaces at the upper end and the lower end are communicated, and when the lower closing cap 13 is closed, the spaces at the upper end and the lower end are not communicated.
Regarding the pressing body:
(1) The inner cylinder 6 is internally provided with a pressing body which is matched with the inner cylinder 6 by a piston, so that the inner cylinder 6 can move up and down, can be pressed down by external force, and can reset under the rebound force of the telescopic spring 10 when no external force acts.
(2) Structurally, it is: the pressing body comprises a top cover 7, a piston body 8 and a piston plate 9 which are sequentially connected from top to bottom and coaxially arranged, and because the piston body 8 and the piston plate 9 are positioned in the inner cylinder body 6 and are in piston fit with the inner cylinder body 6, the inner cylinder body 6 is also divided into an upper space and a lower space which are not communicated by the piston body 8 and the piston plate 9, and because a vent pipe 11 is arranged in the piston body 8, a through hole and an upper closing cap 12 are arranged at the bottom of the piston plate 9, when the upper closing cap 12 is opened, the upper space and the lower space of the inner cylinder body 6 are communicated, and when the upper closing cap 12 is closed, the upper space and the lower space of the inner cylinder body 6 are not communicated.
Regarding the breather pipe 11: the breather pipe 11 is specially designed, one end of the breather pipe is positioned at the top of the side wall of the piston body 8, and the other end of the breather pipe is positioned at the center of the bottom of the piston body 8, and the purpose of the breather pipe is that the upper closing cap 12 and the lower closing cap 13 are matched to generate pressure for controlling the pneumatic piston 14.
With respect to the ventilation pipe 11, the upper closing cover 12 and the lower closing cover 13 are engaged:
(1) When the pressing body of the present invention is not pressed, the extension spring 10 is in a relaxed state, and the top end of the ventilation pipe 11 is not located in the inner cylinder 6 but exposed to the outside air. Also, since the extension spring 10 is opened and the lower closing cap 13 is closed in the reset, i.e., relaxed state, in the present invention, the space between the upper closing cap 12 and the lower closing cap 13 is communicated with the outside through the vent pipe 11, and a section of air exists between the upper closing cap 12 and the lower closing cap 13. We call the space between the upper closure 12 and the lower closure 13 a transition space.
(2) The expansion spring 10 is pressed, the pressure of the gas in the transition space is increased, the upper closing cover 12 is closed by the gas pushing-up, at this time, the transition space is isolated from the outside air, and the outside air cannot enter the transition space through the ventilation pipe 11.
On the premise that the transition space is closed, the telescopic spring 10 is compressed, the transition space is reduced, the gas pressure is downwards pushed, the lower closing cover 13 is opened, and the gas enters the pen tube 1 to push the pneumatic piston 14 to downwards move.
(3) After the operation is finished, the vacuum pressing device is not pressed any more, the upper sealing cover 12 is opened at the same time, the transition space is communicated with the outside through the vent pipe 11, meanwhile, the gas in the pen tube 1 is not input any more, the lower sealing cover 13 is closed by the rebound of the gas pressure, and the state in (1) is returned.
Regarding the air pressure piston 14: the space between the inner cylinder 6 and the top of the ink body 3 is also not communicated with the space between the upper and lower ends of the pneumatic piston 14, so that when the upper pressure pushes it down, it moves down to push the ink body 3 down, thereby squeezing out air bubbles in the ink body 3 or letting the ink body 3 enter the lower pen head 2.
The working flow of the vacuum pressing device is as follows:
(1) The pressing body is pressed down, all parts in the vacuum pressing device are matched, the upper sealing cover 12 is combined to be closed, the lower sealing cover 13 is opened, gas enters the pen tube 1, and the ink body 3 moves downwards for a certain distance;
(2) Releasing the pressing body, opening the upper closing cover 12 at the moment, closing the lower closing cover 13, and resetting all parts in the vacuum pressing device; if the ink body 3 is not moved down sufficiently at this time, the step (1) is repeated.
The purpose of the bleed valve arrangement is:
(1) When ink disconnection may occur in the pen tube 1 after the pen core falls down on the ground carelessly, and insufficient ink supply may occur in the subsequent use, the ink is required to be matched with the air release valve device for use, so that the gas of the disconnected part of the ink body 3 is discharged from the air release valve port to enable the ink to be continuously supplied to the pen head 5, and the ink is recovered for use.
(2) According to the invention, the pen head 2 can be replaced, when the pen head 2 is damaged and replaced, the air pressure in the new pen head 2 is not communicated with the ink body 3 in the pen tube 1, so that the air pressure in the pen head 2 is released by matching with the air release valve device and the vacuum pressing device, and the ink body 3 in the pen tube 1 is pressed down into the pen head 2, so that the pen is recovered.
Regarding the detachable connection: the pen head 2 and the pen tube 1 are detachably connected, so that the pen head 2 can be replaced, and in the invention, the detachable connection is realized by rotary clamping under the cooperation of the spring ball 30, the vertical groove 31 and the horizontal groove 32. The vertical grooves 31, 32 are used for positioning, and the first and second pipes 15, 16 are just right opposite when the spring balls 30 are slid into place.
Regarding the internal structure of the first duct 15: the first vertical rod 19 can move up and down along the strip-shaped groove under the action of the pushing piece 20, and since the first annular plate 17 is fixed at the bottom of the first pipeline 15 and the second annular plate 18 is fixedly connected with the first vertical rod 19, when the pushing plate moves up and down, the first annular plate 17 is not moved, the second annular plate 18 moves up and down along with the first vertical rod 19, and the first vertical rod 19 can pass through the first annular plate 17 to touch the second vertical rod 24 below. The first spring body 21 aims to drive the first vertical rod 19 to automatically move upwards for resetting.
Regarding the internal structure of the second pipe 16: similarly, when the first vertical rod 19 moves downward, the third annular plate 22 passes through the first annular plate 17 to touch the second vertical rod 24 below, so that the second vertical rod 24 moves downward to drive the traction mechanism 27 to move, thereby opening the plug 26, releasing the air pressure in the pen head 5 and enabling the ink body 3 to move downward into the pen head 5. The second spring body 25 aims to drive the second vertical rod 24 to automatically move upwards to reset under the action of no external force, and simultaneously, the plug 26 is closed.
The vacuum pressing device and the air release valve device are matched for use, so that the ink body 3 can be quickly and completely fused into the pen point 5, and the pen point can be better used.
In the using process, if the pen point 5 is broken and the pen cannot be used normally, the pen head 2 can be directly replaced, and one pen tube 1 can be matched with 2-3 pen point parts 2.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
