Description

A fountain pen for correcting sitting posture Technical Field

[0001] The invention relates to the technical field of learning tools, in particular to a fountain pen for correcting sitting posture. Background Art

[0002] During the learning process, students' sitting posture plays a crucial role in their physical development. When doing homework, students often become fatigued due to sitting for long periods of time. They often lean over their desks or bend over to do their homework. Over time, this not only affects their vision but also their physical development, particularly their spine. Therefore, correct sitting posture has a significant impact on students. Since students often use pens while doing their homework, having a monitoring device on the pen to remind users to pay attention to their sitting posture would be a valuable monitoring tool.

[0003] Chinese patent CN2015210925600 discloses a pen that corrects sitting posture. The pen barrel is equipped with a magnetic device and an infrared sensor. The infrared sensor monitors the distance between the user's head and the pen in real time. When the user lowers their head, the controller determines that the distance between the user's head and the pen is lower than a set value, indicating that the sitting posture is incorrect. The controller controls the magnetic device through a relay to retract the pen refill into the barrel, preventing normal writing, thereby correcting the sitting posture. This type of pen is complex, easily damaged, and expensive.

[0004] Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a pen for correcting sitting posture which has a simple structure, low cost and is easy to use.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] The present invention provides a pen for correcting sitting posture, comprising a matching pen barrel and a pen cap. A writing nib is provided at the bottom end of the pen barrel, an ink sac and an ink guide tube are provided in the inner cavity of the pen barrel from top to bottom, and the ink guide tube connects the ink sac and the nib. A switch valve for controlling the passage of ink is provided at the connection between the ink sac and the ink guide tube. A detector for monitoring the distance between the user's head and the pen, a microprocessor for controlling the operation of the switch valve, and a sheet battery for powering the microprocessor are provided at the top end of the pen barrel. The input end of the microprocessor is respectively connected to the output end of the sheet battery and the output end of the detector, and the output end of the microprocessor is connected to the controlled end of the switch valve.

[0008] In the above-mentioned pen for correcting sitting posture, the detector is a distance sensor.

[0009] In the above-mentioned pen for correcting sitting posture, a contact sensor for sensing the user's holding position is provided on the side wall of the grip portion of the pen body, and the output end of the contact sensor is connected to the input end of the microprocessor.

[0010] In the above-mentioned pen for correcting sitting posture, the buckling portion between the pen body and the pen cap is provided with a push switch, and the push switch is connected in series between the sheet battery and the power supply terminal of the microprocessor through a wire.

[0011] Compared with the prior art, the present invention has achieved the following technical effects:

[0012] The present invention can determine the user's sitting posture by arranging a switch valve between the ink sac and the ink guide tube, and arranging a battery, a microprocessor, and a distance sensor at the top of the pen body. The ink supply is controlled by controlling the switch valve, thereby correcting the sitting posture. The invention has the characteristics of simple structure, low cost, and not easy to damage. A contact sensor is arranged on the grip of the pen body to determine whether the user's pen-holding posture is correct. If it is incorrect, the ink supply is also cut off by controlling the switch valve to serve as a reminder to the user. A push switch is arranged at the part where the pen cap and the pen body are interlocked, and is used for the microprocessor to determine the use status of the pen. When the pen is uncapped and used, the push switch is released, and the wire between the microprocessor and the sheet battery is connected, and power is started to monitor the user's sitting posture, thereby saving energy and extending the use time of the sheet battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] FIG1 is a schematic structural diagram of the present invention;

[0014] Figure 2 is the electrical schematic.

[0015] In the figure: 1. Pen tip, 2. Ink sac, 3. Ink guide tube, 4. Switch valve, 5. Sheet battery, 6. Microprocessor, 7. Distance sensor, 8. Press switch, 9. Contact sensor. DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A fountain pen for correcting sitting posture comprises a matching pen body and pen cap. A writing nib 1 is provided at the bottom end of the pen body, as shown in FIG1 . An ink sac 2 and an ink guide tube 3 are provided in the inner cavity of the pen body from top to bottom. The ink guide tube 3 connects the ink sac 2 and the nib 1. A switch valve 4 is provided at the connection between the ink sac 2 and the ink guide tube 3 for controlling the flow of ink from the ink sac to the nib. A detector, a microprocessor 6 and a sheet battery 5 are provided at the top end of the pen body. The input end of the microprocessor 6 is respectively connected to the output end of the sheet battery 5 and the output end of the detector. The output end of the microprocessor 6 is connected to the controlled end of the switch valve 4. The electrical connection relationship of each component is shown in FIG2 .

[0018] The detector is used to monitor the distance between the user's head and the pen while using the present invention. In this embodiment, the detector uses a distance sensor 7; a sheet battery 5 is used to power a microprocessor. The microprocessor is used to determine whether the user's sitting posture is correct based on the signal from the distance sensor 7 and control the operation of the switch valve. When the sitting posture is correct and the distance between the user's head and the pen is within the set range, the switch valve opens, and the ink in the ink sac flows down to the pen tip, allowing normal writing. When the sitting posture is incorrect, resulting in the distance between the user's head and the pen being less than the set value, the switch valve is controlled to close, cutting off the ink supply. The pen tip is free of ink and cannot be written, thus correcting the sitting posture.

[0019] To monitor the user's correct pen-holding posture, a contact sensor 9 is provided on the sidewall of the pen's grip to sense the user's grip position. The output of the contact sensor is connected to the input of the microprocessor. If the pen is held incorrectly, the ink supply is shut off by controlling the on-off valve. This depletes the ink supply to the pen tip, preventing writing and alerting the user.

[0020] In the present invention, a push switch 8 is provided at the fastening portion between the pen barrel and the pen cap. The push switch is connected in series between a sheet battery and a power supply terminal of a microprocessor via a wire. This switch is used to monitor whether the pen is in use. When the user opens the pen cap to use it, the push switch is released, connecting the wire between the microprocessor and the sheet battery, and starting to supply power to monitor the user's sitting posture. When the pen cap and pen barrel are fastened, the push switch is pressed, disconnecting the wire between the microprocessor and the sheet battery, and the sheet battery stops supplying power, thus saving energy.
