[0001] The utility model relates to the technical field of watercolor pens, in particular to a portable leak-proof soft-head watercolor pen. Background Art

[0002] Watercolor pen, a kind of painting tool. Watercolor pen is a common painting tool for children. The pen head material is generally carbon fiber. It is usually sold in boxes of 12 colors, 24 colors, and 36 colors. The pen head is generally round, and the two colors are not easy to blend together. It is generally suitable for children's paintings and can also be used as a marker.

[0003] A portable leak-proof soft-head watercolor pen currently in use has been found through retrieval that a utility model with patent publication number CN219686920U discloses an assembled watercolor pen, comprising a watercolor pen body, the watercolor pen body comprising a pen cap and a pen barrel, the upper surface of the pen cap is provided with a connecting column, the outer surface of the connecting column is provided with a limiting block, the bottom of the pen barrel is provided with a connecting groove, the inner surface of the connecting groove is provided with a sliding groove and a limiting groove, the watercolor pen body is designed as a hexagonal prism structure, and two adjacent surfaces of the watercolor pen body are respectively provided with a limiting sliding groove and a trapezoidal protrusion. Through the design of the utility model, when it is necessary to organize and collect the watercolor pens, it is only necessary to slide the limiting sliding groove of one watercolor pen and the trapezoidal protrusion of another watercolor pen to complete the splicing of the watercolor pens. After splicing, the gaps between the watercolor pens are small, the space utilization rate is high, and the watercolor pens can be placed together after splicing, making the arrangement and collection of the watercolor pens more convenient and improving the convenience of using the watercolor pens.

[0004] Although the above patents solve the problems in the above-mentioned background technology, they still have the following shortcomings: 1.

[0029] For examples, see Figure 1-5 , the utility model provides a technical solution:

[0030] A portable leak-proof soft-tip watercolor pen comprises a pen holder 1 and a pen cap 2. A pen cap 3 is arranged on the top of the pen holder 1, a sealing ring 301 is arranged on the bottom of the pen cap 3, a pen head holder 4 and a groove 5 are respectively installed on the bottom of the pen holder 1, a pen core 401 is arranged through the bottom of the pen head holder 4, a leak-proof mechanism 6 is arranged between the pen core 401 and the pen head holder 4, a magnetic suction block 501 is fixedly installed inside the groove 5, a filling bin 7 is opened inside the pen holder 1, and a magnetic suction ring 201 is fixedly installed on the top side of the pen cap 2;

[0031] Specifically, the top inner wall of the filling chamber 7 extends to the top surface of the pen holder 1 and is provided with an internal thread groove, and the outer bottom surface of the pen cap 3 is provided with an external thread groove that is screwed with the internal thread groove;

[0032] In this embodiment, the pen cap 3 and the pen holder 1 are fixed by the screwing arrangement between the internal thread groove and the external thread groove, and the arrangement of the sealing ring 301 can improve the sealing performance between the pen cap 3 and the pen holder 1 .

[0033] Specifically, the groove 5 is provided at the bottom side of the pen holder 1, the outer surface of the magnetic ring 201 is in contact with the groove 5, and the magnetic ring 201 is magnetically connected to the magnetic block 501;

[0034] In the present embodiment, the magnetic ring 201 is mainly arranged to form a magnetic contact with the magnetic block 501 , thereby achieving the effect of attracting the pen cap 2 and the pen holder 1 , thereby protecting the pen core 401 .

[0035] It should be noted that the pen core 401 is made of a flexible fiber material in one piece.

[0036] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The anti-leakage mechanism 6 includes an anti-leakage column 601 and a baffle 602. The anti-leakage column 601 is fitted on the outside of the refill 401, and a square groove 603 is provided on its outer surface. The baffle 602 is arranged at the inner bottom end of the filling bin 7, and a connecting rod 604 and a return spring 605 are provided at the bottom thereof. A water leakage groove 606 is provided on the top surface of the baffle 602.

[0037] Specifically, the top of the pen holder 4 extends to the inner bottom of the filling bin 7, and its outer surface is in sealed and fixed contact with the inner wall of the filling bin 7, the bottom of the connecting rod 604 is fixed to the top side of the pen holder 4, the outer surface of the leak-proof column 601 fits and slides with the inner wall of the pen holder 4, and its top passes through the top inner wall of the pen holder 4 and is fixedly connected to the bottom end of the reset spring 605, and the bottom inner wall of the water leakage groove 606 is flush with the bottom surface of the baffle 602;

[0038] In the present embodiment, the connection rod 604 is mainly used to fix the baffle 602, the leakage groove 606 is mainly used to allow the colored water to pass through the baffle 602, the square groove 603 is mainly used to facilitate the contact between the colored water and the pen core 401, and the reset spring 605 is mainly used to reset and support the anti-leakage column 601, so that the anti-leakage column 601 can be fitly immersed in the interior of the pen head seat 4, thereby preventing the colored water from contacting the pen core 401, thereby achieving the anti-leakage effect and meeting the carrying needs of the user.

[0039] The working process of the utility model is as follows: when a portable leak-proof soft-head watercolor pen is used, the pen cap 2 is attracted to the pen holder 1 under the magnetic attraction cooperation of the magnetic attraction ring 201 and the magnetic attraction block 501, so that the pen holder 4 and the pen core 401 are protected. When the pen core 401 contacts the paper, the pen core 401 moves and drives the leak-proof column 601 to squeeze the return spring 605, and then the return spring 605 gradually contracts until the square groove 603 enters the filling bin 7. At this time, the colored water passes through the leaking groove 606 and the square groove 603 in turn and contacts the pen core 401, so that the pen core 401 is filled with the colored water. The watercolor pen is soaked, thereby realizing the color painting of the watercolor pen. When the pen core 401 is separated from the paper, the return spring 605 in the compressed state begins to stretch and drives the leak-proof column 601 to move. The leak-proof column 601 slides along the inner wall of the pen head seat 4 until the square groove 603 is completely separated from the filling bin 7, so that the flow path of the colored water is blocked, thereby realizing the leak-proof protection of the watercolor pen, which is convenient for users to carry. Furthermore, through the setting of the internal thread groove and the external thread groove, the pen cap 3 and the filling bin 7 are screwed together and rotated, which is convenient for adding colored water inside the filling bin 7, thereby improving the practical effect of the watercolor pen.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
