DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0026] Embodiment 1: A convenient office fountain pen for adding ink, such as Figure 1-Figure 6 As shown, it includes a pen body 1; an observation slot 1003 is provided on the outer shell 1001 of the pen body 1, and a protective plate of a transparent material is provided on the observation slot 1003;

[0027] It also includes a steel block 101, a rope 102, a fixing ring 103 and a buckle 104; an ink bag 1004 is installed in the pen body 1, and the ink bag 1004 occupies the middle and upper areas of the pen body 1; a piston 1005 is arranged in the ink bag 1004; the steel block 101 is fixedly connected to the upper side of the piston 1005; the rope 102 is fixedly connected to the upper side of the steel block 101, and the rope 102 is set to be made of nylon, polyester fiber, cotton rope and other materials; a through hole 1006 is opened at the upper end of the ink bag 1004, and the rope 102 will pass through the through hole 1006; the outer shell The inner wall of 1001 is slidably connected with a fixed ring 103; a sliding block 10301 is arranged on the fixed ring 103, and the other end of the rope 102 is fixedly connected to the upper side of the sliding block 10301; a notch 10302 is provided on the fixed ring 103; a movable groove 1002 is provided on the outer shell 1001, and the sliding block 10301 passes through the movable groove 1002, and the sliding block 10301 is limited by the movable groove 1002, so that the sliding block 10301 moves along the movable groove 1002; the movable groove 1002 on the outer shell 1001 is provided. A buckle 104 is installed above the slot 1002, and the rope 102 passes through the buckle 104; a spring 10401 is fixedly connected to the buckle 104; the other end of the spring 10401 is fixedly connected to a hemispherical block 10402; a clamping hole 10403 is opened on the buckle 104; when the pen needs to be refilled with ink, the user moves the buckle 104 to release the fixation of the rope 102, at this time, the piston 1005 will move downwards along the inner wall of the ink sac 1004 under the gravity of the steel block 101, and the piston 1005 and the steel block 101 are moved downwards. During movement, the fixed ring 103 and the parts thereon will move upward along the movable groove 1002 on the outer shell 1001 under the pull of the rope 102. After the piston 1005 and the steel block 101 move to the bottom of the ink sac 1004, the user controls the sliding block 10301 on the fixed ring 103 to move downward along the movable groove 1002 on the outer shell 1001, thereby pulling the piston 1005 and the steel block 101 upward along the inner wall of the ink sac 1004 through the rope 102, thereby completing the ink adding operation.

[0028] The fixing ring 103 is made of a flexible material; when the fixing ring 103 moves in the housing 1001 , the fixing ring 103 is prevented from damaging the housing 1001 .

[0029] The sliding block 10301 is provided with a plurality of protrusions for increasing the friction force when a human hand contacts it.

[0030] The sliding block 10301 is set to a curved surface, so that when a human hand touches it, it can completely fit the sliding block 10301 for operation, which is ergonomic.

[0031] The pen body 1 also includes a hose 201, a mounting ring 202 and a closing block 203; the upper part of the ink bag 1004 on the pen body 1 is connected to the hose 201, and the other end of the hose 201 penetrates the upper part of the shell 1001 on the pen body 1; the penetration point between the hose 201 and the shell 1001 on the pen body 1 is located above the piston 1005; the air in the ink bag 1004 is discharged through the hose 201, thereby increasing the ink storage of the ink bag 1004; the upper part of the shell 1001 is fixedly connected to the mounting ring 202; the mounting ring 202 is provided with a mounting groove 202 01, the installation groove 20201 is located at the connection point between the hose 201 and the shell 1001; the installation groove 20201 is slidably connected to the closing block 203 through the slide groove 20202; four sliding rods 20302 symmetrically distributed up and down are fixedly connected to the closing block 203, and the sliding rods 20302 are embedded in the slide groove 20202; a protrusion 20301 is provided on the closing block 203; an air outlet 20303 is opened on the closing block 203; by moving the closing block 203, the connection between the air outlet 20303 and the hose 201 is controlled.

[0032] The sealing block 203 is made of rubber material in order to better improve the sealing performance of the sealing block 203 on the hose 201 .

[0033] A plurality of protrusions are arranged on the upper side of the closing block 203 in order to better increase the friction between the closing block 203 and the human hand.

[0034] In an existing fountain pen, the ink sac 1004 usually only occupies the middle area of ​​the fountain pen, and a suction structure is provided on the upper part. Therefore, the ink storage capacity of the ink sac 1004 is relatively small. In addition, because the ink sac 1004 is at a certain distance from the fountain pen tip, after the fountain pen is filled with ink, there is a certain distance between the piston 1005 in the suction structure and the ink surface in the ink sac 1004, that is, there is air in the ink sac 1004, which makes the ink sac 1004 unable to fully store ink, thereby further reducing the ink storage capacity of the ink sac 1004. When the user needs to add ink, he needs to turn down the knob of the fountain pen shell 1001 and then perform the ink adding operation, which is relatively cumbersome.

[0035] When the user needs to add ink to the pen, the user first moves the buckle 104 to make the hemispherical block 10402 on the buckle 104 leave the clamping hole 10403 on the buckle 104, and then when the hemispherical block 10402 moves into the groove on the buckle 104, the rope 102 can move freely, thereby releasing the fixation of the rope 102. Figure 4As shown, the piston 1005 will move downward along the inner wall of the ink sac 1004 under the action of the gravity of the steel block 101. When the piston 1005 moves to the bottom of the ink sac 1004, the fixed ring 103 and the sliding block 10301 will move upward along the movable groove 1002 on the shell 1001 under the pull of the rope 102, and reach the upper end of the movable groove 1002. At this time, the user inserts the lower part of the pen body 1 into the ink bottle, and then the user presses the sliding block 10301 and moves downward along the movable groove 1002 on the shell 1001, thereby pulling the rope 102, thereby pulling the piston 1005 and the steel block 101 to move upward along the inner wall of the ink sac 1004, so as to use the movement of the piston 1005 to form a negative pressure for ink absorption.

[0036] It should be noted that the initial state of the rope 102 is that the buckle 104 fixes the rope 102 , specifically, the hemispherical block 10402 on the buckle 104 is stuck in the hole 10403 , and the rope 102 is in a bent state in the buckle 104 , thereby fixing the rope 102 .

[0037] It should be noted that the ink bag 1004 occupies the middle and upper regions of the pen body 1 , thereby increasing the ink storage capacity of the ink bag 1004 .

[0038] When the piston 1005 and the steel block 101 move to the upper end of the ink sac 1004, the ink filling operation of the fountain pen is completed. However, since there is air in the ink sac 1004, the ink sac 1004 cannot store ink completely, thereby reducing the ink storage capacity of the ink sac 1004. Therefore, the user presses the protrusion 20301 on the closing block 203 and moves along the slide groove 20202 on the mounting ring 202, so that the air outlet 20303 on the mounting ring 202 is connected with the hose 201, and then the user controls the fixing ring 103 to slowly move upward along the movable groove 1002, thereby controlling the piston 1005 and the steel block 101 to slowly move downward along the inner wall of the ink sac 1004, so that the ink in the ink sac 1004 is squeezed by the piston 1005 and the steel block 101. The air in the ink bag 1004 is discharged through the hose 201, and the piston 1005 and the steel block 101 continue to descend, and finally come into contact with the ink surface in the ink bag 1004, thereby discharging the air in the ink bag 1004. Then, the user moves the closing block 203 to close the hose 201, and then the user moves the sliding block 10301 on the fixed ring 103 downward along the movable groove 1002, thereby pulling the piston 1005 and the steel block 101 upward along the inner wall of the ink bag 1004 through the rope 102, and then performing the ink absorption operation again, so as to replenish the space originally occupied by air in the ink bag 1004, so that the ink bag 1004 can be completely filled with ink, and the ink storage capacity of the ink bag 1004 is further increased.

[0039] It should be noted that, in order to prevent the fixing ring 103 from being blocked by the hose 201 , the fixing ring 103 avoids the hose 201 by designing a notch 10302 when moving to the hose 201 .

[0040] It should be noted that after the conventional fountain pen is filled with ink, the distance between the lower side of the piston 1005 and the ink surface in the ink bag 1004 is usually fixed. Therefore, the hose 201 is connected above the ink surface in the ink bag 1004 and below the piston 1005.

[0041] It should be noted that the connection point between the upper end of the hose 201 and the housing 1001 is higher than the piston 1005. Therefore, after the ink bag 1004 is filled with ink, there is air in the upper end of the hose 201, thereby preventing the ink bag 1004 from being filled with ink without air and affecting the circulation of ink.

[0042] After completing the ink filling operation, the user moves the buckle 104 to fix the rope 102 to prevent the piston 1005 and the steel block 101 from moving downward to squeeze the ink in the ink bag 1004, causing the ink to flow out of the pen body 1 and reduce the use effect of the present invention. Therefore, when the user is bored, he can move the sliding block 10301 up and down along the movable groove 1002 to relieve the pressure, thereby improving the use effect of the present invention.

[0043] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 7 As shown, it also includes a storage box 301, a water-repellent cloth 302 and a rubber ring 303; the storage box 301 is fixedly connected to the lower part of the pen body 1; the water-repellent cloth 302 is stored in the storage groove 30101 on the storage box 301; and the rubber ring 303 is fixedly connected to the lower end of the water-repellent cloth 302.

[0044] The rubber ring 303 is made of elastic rubber material in order to better fix the water-repellent cloth 302 on the pen body 1 .

[0045] The water-repellent cloth 302 is made of elastic material so as to better fit the water-repellent cloth 302 to the lower part of the pen body 1 .

[0046] After the user inserts the pen body 1 into the ink bottle, it is difficult for the user to judge the insertion depth of the pen body 1 into the ink bottle due to the uncertain ink surface in the ink bottle, which causes a large area of ​​the lower part of the pen body 1 to be immersed in the ink. After the pen body 1 is taken out of the ink bottle, the lower part of the pen body 1 will be stained with a large amount of ink. Further, when the pen body 1 is taken out of the ink bottle, the ink stained on the lower part of the pen body 1 may drip onto the desktop and clothes, reducing the user experience of the pen body 1.

[0047] Therefore, before the user inserts the pen body 1 into the ink bottle, the user pulls the water-repellent cloth 302 downwards through the rubber ring 303. Figure 7As shown, the water-repellent cloth 302 covers the lower part of the pen body 1. When the rubber ring 303 reaches the bottom of the pen body 1, the user loosens the rubber ring 303, and the rubber ring 303 contracts elastically and is stuck at the bottom of the pen body 1, thereby fixing the water-repellent cloth 302 covering the lower part of the pen body 1 through the rubber ring 303. Figure 1 As shown, therefore, the performance of the water-repellent cloth 302 allows the ink to drip quickly and naturally, and the user can also vibrate the pen body 1 to improve the ink dripping effect. At the same time, it can also prevent the ink from sticking to the lower part of the pen body 1, thereby improving the use effect of the present invention.

[0048] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
