[0032] A paint touch-up pen according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] Reference Figure 1 A paint touch-up pen according to an embodiment of the present invention includes a pen holder 100, a pen mouth 110 and a paint squeezing component.

[0034] As for the pen barrel 100 , both ends of the pen barrel 100 are connected, and the interior of the pen barrel 100 is used to accommodate paint, so that the paint touch-up pen can pre-store paint, eliminating the need to dip the paint touch-up pen in paint when in use.

[0035] As for the pen tip 110, both ends of the pen tip 110 are connected, one end of the pen tip 110 is connected to the front end of the pen barrel 100, and a brush head 120 is provided at the end of the pen tip 110 away from the pen barrel 100. Therefore, the paint in the pen barrel 100 can flow through the pen tip 110 to the brush head 120, so that the brush head 120 can brush the paint on the paint surface to be repaired.

[0036] Furthermore, the inner cavity of the nib 110 is provided with a stopper ball 130 and a first spring 140, and the inner cavity of the nib 110 is provided with a first inner convex ring 150. The stopper ball 130 is located at the end of the first inner convex ring 150 away from the pen barrel 100, and one end of the first spring 140 abuts against the side of the stopper ball 130 away from the first inner convex ring 150, and one end of the first spring 140 abuts against the inner cavity of the nib 110.

[0037] It can be understood that the first spring 140 can squeeze the stopper ball 130 to abut against the first inner convex ring 150. When the paint in the pen barrel 100 is not squeezed, the first spring 140 drives the stopper ball 130 to cooperate with the first inner convex ring 150 to seal the pen tip 110, so that the paint in the pen barrel 100 will not flow into the pen tip 110, thereby preventing the pen tip 110 from discharging paint too quickly or leaking paint when the touch-up pen is not in use. When the paint in the pen barrel 100 is squeezed, the paint squeezes the stopper ball 130, causing the stopper ball 130 to move away from the first inner convex ring 150. As a result, the pen barrel 100 and the pen tip 110 are connected, and paint can flow from the pen barrel 100 into the pen tip 110.

[0038] Reference Figure 2 As for the paint squeezing assembly, the paint squeezing assembly includes a piston 160, a first screw 170 and a first sleeve 180. The piston 160 is slidably arranged in the pen barrel 100. One end of the first screw 170 is connected to the piston 160, and the other end of the first screw 170 extends toward the rear end of the pen barrel 100. The first sleeve 180 is fixed in the pen barrel 100. The first screw 170 is threadedly connected to the first sleeve 180. The first screw 170 rotates to drive the piston 160 to slide in the pen barrel 100.

[0039] It can be understood that when the first screw 170 is driven to rotate, the threaded connection between the first screw 170 and the first sleeve 180 enables the first screw 170 to move, thereby enabling the first screw 170 to drive the piston 160 to move in the pen barrel 100, and then enabling the piston 160 to squeeze the paint in the pen barrel 100 toward the pen tip 110. In addition, the cooperation of the first screw 170 and the first sleeve 180 drives the piston 160 to move, making the movement of the piston 160 more stable, thereby improving the control accuracy of the paint output of the paint touch-up pen.

[0040] In some specific embodiments, a driving assembly is further included. The driving assembly is arranged at the rear end of the pen barrel 100. The driving assembly is used to drive the first screw 170 to rotate, thereby facilitating the use of external force to drive the first screw 170 to rotate, thereby making the paint squeezing operation of the paint touch-up pen more convenient.

[0041] Specifically, the driving assembly includes a guide member 190 arranged in the pen barrel 100, a pressing member 200 slidingly connected to the guide member 190, a rotating member 210 rotatably arranged in the pen barrel 100, and a second spring 220 located between the rotating member 210 and the first screw sleeve 180. The guide member 190 has a plurality of guide grooves 230 arranged along the circumference of the pen barrel 100, and the rotating member 210 is correspondingly provided with a plurality of guide bars 240. The guide grooves 230 cooperate with the guide bars 240 to limit the position. A serration 250 is provided at one end of the pressing member 200 close to the pen barrel 100, and a first inclined surface 260 is provided at one end of the guide bar 240 close to the pressing member 200. The serration 250 abuts against the first inclined surface 260 to guide the rotating member 210 to rotate. The rotating member 210 rotates to drive the first screw 170 to rotate. The second spring 220 is used to drive the rotating member 210 to move toward the rear end of the pen barrel 100.

[0042] When the user presses the pressing member 200, the saw teeth 250 of the pressing member 200 abut against the first inclined surface 260 of the guide bar 240 to push the rotating member 210 away from the guide member 190, so that the guide bar 240 disengages from the guide groove 230. When the guide bar 240 disengages from the guide groove 230, the saw teeth 250 cooperate with the first inclined surface 260 to rotate the rotating member 210 along the inclined direction of the first inclined surface 260. When the user releases the pressing member 200, the second spring 220 drives the rotating member 210 to approach the guide member 190, so that the guide bar 240 falls into the next guide groove 230. As a result, when the rotating member 210 rotates, the first screw 170 can rotate, so that the first screw 170 drives the piston 160 to squeeze the paint. Furthermore, each time the user presses and releases the pressing member 200, the rotating member 210 can be controlled to rotate by the same angle, so that the paint output of the paint touch-up pen can be controlled with higher accuracy.

[0043] In some specific embodiments, a partition rib 270 is provided between two adjacent guide grooves 230, and the end of the partition rib 270 has a second inclined surface 280. The second inclined surface 280 abuts against the first inclined surface 260 to guide the guide bar 240 into the guide groove 230, thereby enabling the guide bar 240 to enter the guide groove 230 more accurately.

[0044] In some specific embodiments, the outer side surface of the pressing member 200 has a first step 310, and the rear end of the pen holder 100 has a second inner convex ring 320. The second inner convex ring 320 abuts against the first step 310 to prevent it from falling off, thereby preventing the pressing member 200 from falling off the pen holder 100.

[0045] Reference Figure 3 In some specific embodiments, the side surface of the first screw 170 has a clamping plane 290 extending along the length direction of the first screw 170, and the rotating member 210 has a clamping hole 300 for accommodating the first screw 170. The clamping hole 300 abuts against the clamping plane 290 to stop rotation. Therefore, when the rotating member 210 rotates, the clamping hole 300 can cooperate with the clamping plane 290 to limit and stop rotation, so that the rotating member 210 can drive the first screw 170 to rotate.

[0046] In some specific embodiments, the first screw 170 is rotatably connected to the piston 160 , thereby reducing the frictional resistance experienced by the piston 160 along the rotational direction of the piston 160 , thereby making driving the piston 160 more labor-saving.

[0047] In some specific embodiments, the end of the nib 110 away from the pen barrel 100 has a tapered tube portion 330, and the end of the tapered tube portion 330 away from the pen barrel 100 is installed with a brush head 120, thereby facilitating the reduction of the paint delivery speed of the nib 110 and preventing the nib 110 from delivering paint too quickly and affecting the paint touch-up operation.

[0048] Reference Figure 4 Furthermore, the cross section of the tapered tube portion 330 at one end away from the pen holder 100 is set to be elliptical, and the brush head 120 is set to be flat, thereby increasing the area of the brush head 120 brushing paint and improving the painting efficiency.

[0049] In some specific embodiments, a pen cap 340 is further included, and the pen tip 110 is snap-fitted to the inner wall of the front end of the pen barrel 100. The pen cap 340 is sleeved outside the pen tip 110, and the pen cap 340 is snap-fitted to the outer wall of the front end of the pen barrel 100. Thus, the pen cap 340 can protect the pen tip 110 when the touch-up pen is idle, preventing the pen tip 110 from being damaged by impact.
