Detailed Implementation

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] like Figures 1 to 6As shown, a self-controlled marker pen with a built-in valve according to the first aspect embodiment of this utility model includes a pen barrel 9, a pen tip sleeve 10 sleeved on the upper end of the pen barrel 9, a pen tip 7 installed inside the upper end of the pen tip sleeve 10, a pen tip rod 8 fixedly installed at the bottom of the pen tip 7, a spring 11 fixedly installed at the bottom of the pen tip rod 8, the outer surface of the spring 11 being coated with anti-rust oil, a ball bearing 12 made of acrylic material installed at the bottom of the spring 11, and an ink collection tank 3 installed at the lower end of the pen tip rod 8. Both the ball and the ball are located inside the ink reservoir 3. A sealing element 14 is installed at the bottom of the ink reservoir 3. The sealing element 14 includes a tube 141, with a collar 142 fixedly fitted at the bottom of the tube 141. The bottom of the pen tip sleeve 10 is installed on the collar 142. A sealing port 13 is provided at the top of the sealing element 14. A pen barrel 9 is installed at the bottom of the sealing element 14. A torsion bar mechanism is installed at the bottom of the pen barrel 9. The torsion bar mechanism is used to generate air pressure by pushing forward and pushing the ball 12 upward. The torsion bar mechanism includes a torsion bar 6. The upper end of the pen is fitted with a pen barrel 9. An inner rod 17 is installed inside the torsion bar 6, and a screw 18 is installed inside the inner rod 17. A screw positioning ring 5 is fitted on the upper end of the screw 18, and a positioning nut 16 is installed on the top of the torsion bar 6. When the user twists the torsion bar 6 at the bottom of the pen barrel 9, the twisting of the torsion bar mechanism causes the screw 18 inside the inner rod 17 to move upward, thereby generating air pressure in the ink collection tank 3. The generated air pressure pushes the ball 12 upward, opening the ink sealing port 13, allowing ink to flow out of the ink collection tank 3. The ink flows out through the ink sealing port. The ink flows out through the pen tip 8 and the pen tip 7, allowing for writing or drawing. After the ink flows out of the pen tip 9, the air pressure inside the pen tip 9 will increase as the ink flow space increases and decrease. The ball 12 returns to its original position under the elastic force of the spring 11, and the ink seal 13 closes, stopping the ink flow. If more ink is needed, the torsion lever 6 needs to be rotated again. This process can be repeated. Before stopping using the marker, the user needs to wait until the ink in the pen tip 7 stops overflowing before putting on the pen cap 2.

[0029] Example 2

[0030] like Figures 1 to 6 As shown, including all the contents of Embodiment 1, in addition, a pen cap 2 is fitted on the pen tip cover 10, and the pen tip cover 10 and the pen cap 2 are snapped together. A top cap 1 is fixedly installed through the top of the pen cap 2, and the pen tip 7 is located inside the top cap 1. A slot 19 is opened on the top of the pen cap 2, and a locking post 20 is fixedly installed at the bottom center of the slot 19. The top cap 1 is installed in the slot 19, and the top cap 1 is snapped together with the locking post 20. The top cap 1 directly covers the pen tip 7, which can protect the pen tip from damage or contamination when the marker is not in use and extend the service life of the pen tip.

[0031] Example 3

[0032] like Figures 1 to 6As shown, including all the contents of Embodiment 2, except that a collar head 15 is installed on the top of the screw 18, and a sealing ring 4 is fitted on the collar head 15. The sealing ring 4 is made of rubber. The screw positioning ring 5 is located below the sealing ring 4. The sealing ring 4, the screw positioning ring 5 and the positioning nut 16 are all set inside the lower end of the pen barrel 9. Through the setting of the sealing ring 4, the sealing performance is improved, which can effectively seal the gap between the screw 18 and the pen barrel 9 and ensure that the ink will not leak from the lower end of the pen barrel 9.

[0033] The working principle and usage of this utility model:

[0034] When the marker is needed, the user twists the torsion bar 6 at the bottom of the pen barrel 9. The twisting of the torsion bar mechanism causes the screw 18 inside the inner rod 17 to move upward, thereby generating air pressure in the ink reservoir 3. The generated air pressure pushes the ball 12 upward, opening the ink seal 13, allowing ink to flow out of the ink reservoir 3. The ink flows out through the ink seal 13, passes through the pen tip rod 8, and flows out from the pen tip 7, enabling writing or drawing. After the ink in the pen barrel 9 flows out, the air pressure in the pen barrel 9 will decrease as the ink flow space increases. Under the elastic force of the spring 11, the ball 12 returns to the ink seal 13, closing the ink seal 13 and stopping the ink flow. If more ink is needed, the torsion bar 6 needs to be rotated again. Before stopping the use of the marker, the user needs to wait until the ink in the pen tip 7 no longer overflows before putting on the pen cap 2. At the same time, this structure resists negative pressure and also solves the problem of ink leakage caused by insufficient negative pressure during transportation.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0036] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
