TECHNICAL FIELD
The present disclosure belongs to the technical field of brushes, in particular relating to a two-color pen.
At present, there is a brush that can draw patterns directly in the market. The brush comprises a pen holder and a pattern roller. The pattern roller is rotatably installed at the front end of the pen holder. The rotation axis of the pattern roller is perpendicular to the axis of the pen holder. A winding core and a fiber head for providing pigments are provided in the pen holder. The tail end of the fiber head is inserted into the winding core to suck the pigments in the winding core, and the head end of the fiber head is in sliding contact with the pattern roller. When the pattern roller rolls on the paper, the fiber head can continuously rub the pigment onto the pattern roller, so that the pattern roller can continuously draw the pigment on the paper in the form of a pattern to complete the drawing of the pattern.

Embodiment 1:
As shown in
The present disclosure relates to a two-color pen, in particular to a single-line two-color pen, which comprises a pen body 1, a roller 2 and water supply components; wherein
a cavity is provided in the pen body 1, the head of the pen body 1 is provided with an opening communicated with the cavity; and the roller 2 is rotatably provided at the head of the pen body 1, that is, at the opening of the pen body 1;

The two water supply components in pairs store pigments with different colors. The reset device 5 in the two-color pen can push the water supply components outputting different colors in the direction of the roller 2. When the roller 2 is rolling, the transmission part provided on the roller 2 can alternately push the two water supply components in pairs in the direction away from the roller in sequence, so that one of the water diversion devices 4 is pushed in the direction away from the roller 2 by the transmission part, and the water outlet ends of the two water supply components in pairs can alternately abut against the roller 2 in sequence under the action of the reset device 5. In this way, the roller 2 can draw lines or patterns with two colors (the two colors are intermittently distributed on the lines or patterns), thus better meeting the use requirements of users.
Specifically, there are two water supply components. The two water supply components are both slidably provided in the pen body 1, and the sliding direction of the water supply components is parallel to the length direction of the pen body 1.
The transmission part comprises two transmission parts A23. The two transmission parts A23 are provided at both ends of the roller 2, respectively, and the two transmission parts A23 are in transmission connection with the two water supply components, respectively, so that the two water supply components can be pushed in the direction away from the roller 2 in sequence by the two transmission parts A23, and the roller 2 can draw lines or patterns with two colors.

When the convex surface of the transmission part abuts against the extrusion bump 411, the water diversion seat 41 is pushed in the direction away from the roller 2 by the transmission part, so that the water diversion seat 41 moves in the direction away from the roller 2. In this way, the water outlet end of the water diversion core 42 is separated from the roller 2, and the pigment cannot be delivered to the surface of the roller 2.
Preferably, the cross-sectional shape of the transmission part is fan-shaped, and the cambered surface of the transmission part is an extrusion surface that abuts against and cooperates with the extrusion bump 411.
It should be noted that a plurality of transmission parts may be provided at both ends of the roller 2, and a plurality of transmission parts at the same end are provided around the rotation center of the roller 2 at equal intervals, so as to change the contact frequency between the two water diversion devices 4 and the roller 2, thereby changing the intermittent frequency of the two colors in the lines or patterns drawn by the two-color pen.

One end of the reset device 5 abuts against the opening, the other end of the reset device 5 abuts against the limiting protrusion 412, and the reset device 5 is always in a compressed state. The restoring force generated by the restoring device 5 can push the water diversion seat 41 in the direction away from the cavity.
When the convex surface of the transmission part does not abut against the extrusion bump 411, the restoring force generated by the reset device 5 pushes the water diversion device 4 in the direction of the roller 2, and the water outlet end of the water diversion core 42 abuts against the circumferential side wall of the roller 2.
Preferably, the two-color pen further comprises a limiting base 11, wherein
the limiting base 11 is inserted into the head of the pen body 1, the limiting base 11 is provided with a perforation at the position corresponding to the water diversion device 4, the water diversion end of the water diversion device 4 is in a rod-shaped structure, the water diversion end of the water diversion device 4 is slidably provided in the water storage device 3 through the perforation, and the water diversion end of the water diversion device 4 is always communicated with the water storage device 3 in the sliding process of the water diversion device 4, so that the pigment in the water storage device 3 can be led to the roller 2 through the water diversion device 4.
the end of the reset device 5 far away from the roller 2 abuts against the limiting base 11.
Preferably, the two-color pen further comprises a fixing seat 12; wherein
the fixed base 12 is inserted at one end of the limiting base 11 far away from the pen body 1, two brackets 121 are provided at one end of the fixed base 12 far away from the limiting base 11, and both ends of the roller 2 are rotatably provided on the two brackets 121, respectively, so that the roller 2 is installed more conveniently. The water diversion device 4 is slidably provided between the limiting base 11 and the fixed base 12.
Preferably, the inner side wall of the fixed seat 12 is provided with a chute 122, the length direction of the chute 122 is parallel to the length direction of the pen body 1, the side wall of the water diversion device 4 is provided with a protrusion matched with the chute, and the water diversion device 4 is slidably provided in the fixed seat 12 through the cooperation of the protrusion and the chute, so as to limit the sliding direction of the water diversion device 4. The situation that when the water diversion core 42 abuts against the roller 2, the reaction force generated by the roller 2 to the water diversion core 42 squeezes the water diversion core 42 to the side of the water diversion seat 41 so as to cause the water diversion core 42 to deviate can be avoided, thus making the structure of the two-color pen more stable.
Preferably, the roller 2 has a cylindrical structure, both ends of the roller 2 are provided with rotating shafts 22, the roller 2 is rotatably provided at the head of the pen body 1 through the rotating shaft 22, and the axis of the rotating shaft 22 is perpendicular to the length direction of the pen body 1.

It should be noted that the above pattern ribs can be linear or wavy. When the pattern ribs are linear, the two-color pen can draw straight lines with two alternating colors. When the pattern ribs are wavy, the two-color pen can draw waves with two alternating colors.
In addition, decorative designs or patterns can also be provided on the pattern ribs, so that the two-color pen can draw patterns with two alternating colors.
Preferably, the two-color pen further comprises a pen cap 6, and the pen cap 6 is detachably sleeved on one end of the pen body 1 provided with the roller 2, so as to better protect the roller 2 and avoid the situation that the lines or patterns drawn by the roller 2 are incomplete due to damage of the roller.
Preferably, a pen point 7 is provided at one end of the pen body 1 far away from the roller 2, a water storage part 8 is provided in the pen body 1, and the water diversion end of the pen point 7 is connected with the water storage part 8.
