Description

TECHNICAL FIELD

[0002] The handicraft color drawing pigment anti-dripping pen cap is a pen cap specially designed for handicrafts and color drawing pigments, which mainly prevents the pigments from dripping, drying out or overflowing when not in use, and ensures the stability and cleanliness of the pigments during use.

[0003] In actual implementation process, traditional anti-dripping pen cap still has some problems:

[0004] 1. Many traditional color drawing pen caps are designed without effective anti-dripping structure, and the pigments often leak out due to poor sealing or improper structure design when not in use, causing waste of pigments and possible pollution of the working environment or other objects, especially water-based pigments and oil-based pigments, which are prone to dripping when stored for a long time or accidentally tilted.

[0005] 2. Many traditional pen caps cannot effectively maintain the moisture of the pen tip, especially when not in use for a long time, the pigments are prone to dry out, causing the pen tip to lose its flowability and affecting subsequent use. Poor moisture retention design often leads to the need to clean the pen tip or waste a large amount of pigments.

The bottom end of the buffer rod 601 is fixedly connected with a buffer plate 604. In actual implementation, through the coordinated work of the anti-dripping mechanism 5 and the buffer mechanism 6, the pigment dripping is effectively prevented, and a stable use experience is provided. The anti-dripping mechanism 5 is composed of four levels, which are a protection layer 508, a flow guide layer 510, a wetting layer 511 and a sealing layer 509. The protection layer 508 is made of ABS plastic material and is connected with the flow guide layer 510 through hot pressing welding, thereby providing physical protection and preventing external impact. The flow guide layer 510 is made of polypropylene plastic and is combined with the wetting layer 511 through an adhesive, thereby ensuring the pigment to flow in a predetermined direction and preventing overflow. The wetting layer 511 is made of moisture-absorbing sponge material and is connected with the sealing layer 509 through an adhesive, thereby keeping the pigment moist and avoiding drying. The silica gel sealing layer 509 ensures that the connection between the pen cap 2 and the body 1 of the color pen is completely sealed, thereby preventing the pigment from leaking. When the user inserts the pen head into the protection layer 508, the return spring 505 drives the sliding plate 504 to push the sleeve 502 to completely wrap the pen head, thereby ensuring that the pen head is more closely attached to the pen cap 2, effectively preventing the pigment from leaking. The buffer mechanism 6 includes a buffer rod 601 and a buffer spring 603. The buffer rod 601 is used in a sliding manner with the buffer spring 603, which can effectively absorb external impact and protect the pen cap 2 and the internal structure from being damaged. The pen cap 2 and the pen cap 3 are fixedly connected through clamping connection. The observation slot 501 is used in cooperation with the locking plate 503, thereby enabling the user to check the condition of the pigment and ensuring the close combination of the pen cap 2. The overall design ensures that the pen cap 2 can return to the initial state after being subjected to external force through the cooperation of the sliding plate 504 and the return spring 505, thereby enhancing the stability, sealing property and user experience of the pen cap 2. Not only is the pen head protected, but the pigment is also prevented from leaking when falling.

[0034] Optionally, the inner side of the protection layer 508 is connected with the outer side of the flow guide layer 510 through hot pressing welding. The specific material of the protection layer 508 is ABS plastic. In actual implementation, hot pressing welding can ensure that the protection layer 508 and the flow guide layer 510 are strongly connected, thereby avoiding the damage or separation of the pen cap structure due to external impact or friction. This connection method has good durability and impact resistance, can provide more stable anti-dripping protection, and can ensure that the protection layer 508 will not crack or loosen due to long-term use, thereby greatly improving the service life and reliability.

In actual implementation, the flow guide layer 510 is firmly connected with the wetting layer 511 by the adhesive, so as to ensure smooth flow of the paint during use and avoid overflow or leakage of the paint due to gravity or external force. The polypropylene plastic as the material of the flow guide layer 510 has good chemical resistance and corrosion resistance, and is suitable for long-term contact with chemicals such as paint. In addition, the use of the adhesive ensures the close combination between the flow guide layer 510 and the wetting layer 511, thereby improving the integrity of the entire anti-dripping structure.

[0036] Optionally, the inner side of the wetting layer 511 is connected with the outer side of the sealing layer 509 by an adhesive, and the specific material of the wetting layer 511 is moisture-absorbing sponge, and the specific material of the sealing layer 509 is silica gel. In actual implementation, the wetting layer 511 adopts the moisture-absorbing sponge material and is connected with the sealing layer 509 by the adhesive, so as to ensure that the paint can be kept wet for a long time and prevent drying. The silica gel sealing layer 509 has good elasticity and sealing property, can effectively prevent paint leakage, maintain the wet state of the paint, and ensure the stability of the painting effect. Through this bonding mode, not only the connection strength between the wetting layer 511 and the sealing layer 509 is strengthened, but also the fluidity and wetness of the paint during long-term use are ensured.
