The intelligent pen with the base comprises the ink bottle on the charging seat and the positioning clamping plate for placing the intelligent pen, and the multiple micro liquid sensors are used for automatically judging whether ink in a pen core is insufficient or not and judging the filling state; the miniature liquid pump actively and automatically fills the ink in the ink bottle into the pen core through the capillary needle tube structure of the insertion tube, so that the ink filling treatment work is automatically started and stopped, and after the automatic ink filling treatment is finished, the redundant ink automatically flows back into the ink bottle, so that the ink filling efficiency is improved. And then the positioning clamping plate drives the intelligent pen to rotate downwards to be in a downwards inclined state, and the serious backflow fault phenomenon of ink in the pen core is avoided. The defects that the ink filling state of an automatic ink filling pen still needs to be judged manually, and a large amount of ink overflows and is wasted due to the fact that the ink is filled too much due to manual ink filling treatment are overcome.

Description

Technical Field

[0001] The invention relates to the field of smart pens, and in particular to a smart pen with a base. Background Art

[0002] The existing automatic ink-filling fountain pen requires the user to invert the fountain pen into an upright state and insert it into an ink bottle, and the squeezing ink-filling mechanism in the ink bottle automatically fills ink into the pen core of the fountain pen, without the user having to disassemble the fountain pen to take out the pen core for complicated ink-filling processing. However, the ink-filling operation still needs to be completed manually, and the pen case and the pen core of the fountain pen need to be made of transparent materials for observing the ink filling status, so that the user can judge whether the ink in the pen core is insufficient through the transparent pen case and the pen core, and observe whether the ink is full during the ink filling process. The pen case of the fountain pen cannot be designed with fully enclosed materials, resulting in the overall aesthetics of the fountain pen being far inferior to that of traditional fountain pens. In addition, if the ink is filled manually, it is easy for the ink in the pen core to be overfilled, causing the ink to overflow from the nib component of the pen core or the filling end of the pen core, causing large-scale pollution and waste of ink. Summary of the invention

[0003] In order to overcome the disadvantages that an automatic ink-filling fountain pen still needs to rely on manual judgment of the ink filling status, and manual ink filling is prone to excessive ink filling, resulting in a large amount of ink overflow and waste, the present invention provides a smart pen with a base.

[0019] like Figure 2 As shown, the positioning card plate 3 is rotatably connected to the charging base 1 via a rotating shaft; an electric push rod 31 is rotatably connected to the charging base 1 via a rotating shaft; the telescopic end of the electric push rod 31 is rotatably connected to the positioning card plate 3 via a rotating shaft; a foldable dust cover 32 is fixedly connected between the positioning card plate 3 and the charging base 1 to protect the electric push rod 31.

[0020] like Figure 3As shown, a cover plate 44 is rotatably connected to the pen case 4 via a rotating shaft; a convex structure 441 is arranged inside the cover plate 44; an ejector rod 431 aligned with the convex structure 441 is arranged on the pen core 43, and the user pushes the slide plate 42 to drive the sliding block 41 to push the pen core 43 outward from the inside of the pen case 4, and at the same time, the pen core 43 drives the ejector rod 431 to push the convex structure 441 of the cover plate 44, so that the cover plate 44 is flipped outward and rotated upward, so that the nib part of the pen core 43 can be exposed from the pen case 4 for writing; a permanent magnet 45 is fixedly connected to the cover plate 44, and when writing is not needed, the user pulls the slide plate 42 to drive the sliding block 41 to retract the pen core 43 inward into the pen case 4, and flips the cover plate 44 to cover it back on the pen case 4, so that the cover plate 44 provides dust protection for the pen core 43 in the pen case 4, and at the same time, the cover plate 44 is firmly magnetically attracted to the pen case 4 through the permanent magnet 45.

[0021] The smart pen with a base of the present invention is mainly composed of a smart pen and a charging base 1 with an ink bottle 2. The smart pen is mainly composed of a pen shell 4, a sliding block 41, a slide plate 42, a pen core 43 and a battery 5. The battery 5 supplies power to a circuit module 51 and a micro liquid sensor 52. The micro liquid sensor 52 regularly monitors the ink content in the liquid storage tube component of the pen core 43. Only when the ink covers the surface of the micro liquid sensor 52, the micro liquid sensor 52 will be in a triggered state. When half or more of the micro liquid sensors 52 are triggered by ink, it means that the ink content in the pen core 43 is sufficient to complete a writing work. When less than half of the micro liquid sensors 52 are triggered by ink, it means that the ink content in the pen core 43 is insufficient and automatic ink filling processing is required.

[0022] During the ink filling process, the user places the pen case 4 of the smart pen on the positioning card plate 3 which is initially tilted toward the upper left, and pushes the pen case 4 to drive the pen core 43 and the battery 5 to move toward the insertion tube 23 and the power supply connector 12, until the pen case 4 is clamped on the positioning card plate 3 through the clamp structure, and the charging socket 11 of the charging stand 1 is electrically connected to the external power circuit through the wire, and the power supply connector 12 of the charging stand 1 is directly plugged into the charging port of the battery 5 of the smart pen for electrical connection, and the external power circuit charges the battery 5 through the charging socket 11 and the power supply connector 12 of the charging stand 1, and the battery 5 keeps supplying power to the circuit module 51 and the micro liquid sensor 52, as shown in FIG. Figure 5As shown, at the same time, the capillary needle tube structure 2301 of the cannula 23 is inserted into the ventilation sponge 431 of the pen core 43, so that the cannula 23 is connected to the inside of the pen core 43 through the capillary needle tube structure 2301, and the pen core 43 pushes the wiping block to drive the compression spring 26 to squeeze obliquely downward. At this time, the smart pen and the cannula 23 on the positioning card board 3 are both in a state of being placed obliquely upward to the upper left. After the power supply connector 12 is electrically connected to the battery 5, the power supply connector 12 notifies the micro liquid pump 21 to start through the circuit system, so that the micro liquid pump 21 actively pumps the ink bottle through the infusion tube 22 and the capillary needle tube structure 2301 of the cannula 23. 2 is filled into the pen core 43, and the micro liquid sensor 52 regularly monitors the ink content in the liquid storage tube component of the pen core 43 until all the micro liquid sensors 52 are triggered by the ink, indicating that the ink content in the pen core 43 has been filled to the specified content. At the same time, the circuit module 51 notifies the micro liquid pump 21 to shut down through the circuit system of the battery 5 and the power supply connector 12, and automatically ends the ink filling process to prevent the ink inside the pen core 43 from being overfilled and overflowing. At the same time, the excess ink in the cannula 23 automatically flows back downward along the inner wall of the cannula 23 in a tilted state.

[0023] Afterwards, the electric push rod 31 pulls the positioning card plate 3 to flip downward to a tilted state toward the lower left, so that the positioning card plate 3 drives the smart pen to flip until the nib part of the pen core 43 is tilted toward the lower left, so that the ink in the pen core 43 is in a tilted state toward the nib part, to prevent the pen core 43 from being in a state where the nib part is tilted upward for a long time, causing the ink in the pen core 43 to flow back and fracture, providing long-term static storage protection for the ink in the pen core 43, and the smart pen on the positioning card plate 3 switches from a tilted state toward the upper left to a tilted state toward the lower left, so that the user can intuitively know that the pen core 43 has completed the ink filling work.

[0024] When the user pulls the smart pen out of the positioning card plate 3 to write, during the process of the insert tube 23 leaving the pen core 43, the compressed compression spring 26 pushes the wiping block to move outward along the outer surface of the capillary needle tube structure 2301 of the insert tube 23, and the ink remaining on the outer surface of the capillary needle tube structure 2301 is absorbed by the wiping block to prevent the ink remaining on the outer surface of the capillary needle tube structure 2301 of the insert tube 23 from forming ink lumps after contacting the outside air.

[0025] The use of the entire smart pen does not require the user to worry about the ink content and ink filling status in the pen core 43. The pen can determine whether the ink is sufficient and automatically stop the ink filling process, which truly achieves the goal of using and placing the pen core 43. After the ink filling process is completed, the pen core 43 of the smart pen is placed with the pen tip part tilted to the lower left, which can provide static protection for the ink in the pen core 43.

[0026] Embodiment 2: Based on embodiment 1, Figure 1-Figure 5 As shown, the insert tube 23 of this embodiment is slidably connected to the positioning card plate 3; a push plate 231 is fixedly connected to the insert tube 23; a baffle 13 is fixedly connected to the charging seat 1; the baffle 13 is close to the push plate 231 close to the side of the positioning card plate 3; a tension spring 232 is fixedly connected between the insert tube 23 and the positioning card plate 3, when the insert tube 23 is pulled outward from the positioning card plate 3, the tension spring 232 is stretched, and when the insert tube 23 needs to be pushed back into the positioning card plate 3 later, the stretched tension spring 232 can replace manual work to complete the resetting work; the power supply connector 12 is slidably connected to the positioning card plate 3; the push plate 231 is fixedly connected to the power supply connector 12.

[0027] In this embodiment, when the ink in the pen core 43 is full and the battery 5 has been charged, when the electric push rod 31 pulls the positioning card plate 3 to drive the pen housing 4, the sliding block 41 and the pen core 43 to rotate downward, the baffle 13 will block the cannula 23 rotating downward with the positioning card through the push plate 231, so that the capillary needle tube structure 2301 of the cannula 23 is automatically pulled out from the ventilation sponge 431 of the pen core 43, so as to prevent the capillary needle tube structure 2301 of the cannula 23 from being inserted in the ventilation sponge 431 for a long time. The capillary needle structure 2301 expands a socket structure that is difficult to restore in the ventilation sponge 431 for a long time, affecting the blocking and sealing effect of the ventilation sponge 431 on the ink in the pen core 43. At the same time, the baffle 13 will block the power supply connector 12 that rotates downward with the positioning card through the push plate 231, so that the power supply connector 12 is automatically powered off when it is pulled out of the battery 5, thereby avoiding the battery 5 being in a charging state for a long time due to the user not turning off the charging function for a long time, thereby affecting its service life.

[0028] Embodiment 3: Based on embodiment 2, Figure 1-Figure 6 As shown, the wiping block of the present embodiment is composed of a wiping sponge 24 and a piston 25; a suction chamber structure 2302 is provided in the cannula 23; a piston 25 is slidably connected in the suction chamber structure 2302 of the cannula 23; a wiping sponge 24 is connected to the piston 25; a compression spring 26 is fixedly connected to the wiping sponge 24; the wiping sponge 24 is sleeved on the outer surface of the capillary needle tube structure 2301 of the cannula 23; a plurality of air supply hole structures 2501 penetrating in the left and right directions are provided on the piston 25; a plurality of air suction hole structures 2401 connected to the corresponding air supply hole structures 2501 are provided on the wiping sponge 24; the piston 25 is fixedly connected to the wiping sponge 24 through a threaded structure, and after a large amount of ink is absorbed by the wiping sponge 24, the user only needs to regularly disassemble and replace the wiping sponge 24 through the threaded structure.

[0029] In this embodiment, when the ink in the pen core 43 is full, during the process of the cannula 23 pulling the capillary needle tube structure 2301 away from the ventilation sponge 431 of the pen core 43, the compression spring 26 pushes the wiping sponge 24 to move along the surface of the cannula 23 pulling the capillary needle tube structure 2301, and the ink remaining on the surface of the capillary needle tube structure 2301 is sucked away by the wiping sponge 24. At the same time, the wiping sponge 24 pulls the piston 25 to move outward along the suction cavity structure 2302 in the cannula 23 to perform suction work, so that the external air enters the suction cavity structure 2302 of the cannula 23 through the suction hole structure 2401 of the wiping sponge 24 and the air delivery hole structure 2501 of the piston 25 in turn, so that the outside air passes through the wiping sponge 24 from all directions. The wiping sponge 24 enters the air extraction hole structure 2401, thereby forcing the ink remaining on the surface of the capillary needle tube structure 2301 to be sucked into the wiping sponge 24, thereby improving the absorbing effect of the wiping sponge 24 on the ink remaining on the surface of the capillary needle tube structure 2301, and preventing the ink remaining on the surface of the capillary needle tube structure 2301 from solidifying into lumps, resulting in the subsequent operator inserting the capillary needle tube structure 2301 of the cannula 23 back into the ventilation sponge 431 of the fountain pen core 43. The ink lumps on the surface of the capillary needle tube structure 2301 are transferred to the ventilation sponge 431. If there are a large number of ink lumps in the ventilation sponge 431, it will inevitably affect the ventilation effect of the ventilation sponge 431, and ultimately affect the normal writing function of the fountain pen core 43.
