DETAILED DESCRIPTION

The specific implementation methods of the utility model are further described below in conjunction with Figures 1-4 to make the technical solution of the utility model easier to understand and grasp.

The present application embodiment discloses a direct liquid watercolor pen:

Referring to Figures 1 to 4, a straight liquid watercolor pen includes a pen cap 1, a pen tip 2, a pen neck 3, a pen shaft 4, a fastener 5 and a water guide core 6. The pen neck 3 is installed at the end of the pen shaft 4, the pen tip 2 is fixed in the pen neck 3, a water reservoir 41 is fixed in the pen shaft 4, a liquid storage chamber 42 is opened in the pen shaft 4, one end of the water guide core 6 abuts the pen tip 2, and the other end of the water guide core 6 is connected to the liquid storage chamber 42 after passing through the water reservoir 41. The ink in the liquid storage chamber 42 can be sent to the pen tip 2 for writing through the water guide core 6. The pen shaft 4 is made of polycarbonate. The ink storage capacity of the watercolor pen is larger, the ink fluidity is better, the water discharge is more stable, and the amount of ink left can be observed.

1 to 4 , the pen tip 2 is in the shape of an axe, and is made of a flexible nylon material. A user can draw a wide line through the axe shape or draw a thin line through the sharp point on the axe shape, and the flexible nylon material enhances the wear resistance and corrosion resistance of the pen tip 2.

1 to 4 , the end of the pen tip 2 close to the pen holder 4 is cylindrical and inserted into the pen neck 3. The inner wall of the pen neck 3 is provided with a plurality of limiting ribs 31 along the circumferential direction. The length direction of the limiting ribs 31 is parallel to the length direction of the pen holder 4. The limiting ribs 31 abut against the pen tip 2. The limiting ribs 31 limit the movement of the pen tip 2 along the length direction and fix the pen tip 2 in the limiting ribs 31.

Referring to Figures 1 to 4, the diameter of the part of the pen tip 2 that is plugged into the pen neck 3 is 3-3.5 mm. The diameter of the part of the pen tip 2 that is plugged into the pen neck 3 is limited to between 3 mm and 3.5 mm. The end of the axe-shaped part of the pen tip 2 is arranged in an inclined straight strip shape, and the angle between the inclination direction and the length direction of the pen shaft 4 is 65°-75°. The angle between the inclination direction of the end and the length direction of the pen shaft 4 is limited to 65°-75°. The straight strip edges of the axe-shaped part of the pen tip 2 have rounded corners. The rounded corners can facilitate better contact between the pen tip 2 and the paper.

1 to 4 , the pen cap 1 comprises an inner cylinder 11 which is sealed at one end, an outer cylinder 12 which is open at both ends, and a connecting ring 13. The outer cylinder 12 is sleeved on the outside of the inner cylinder 11, and a gap is left between the outer cylinder 12 and the inner cylinder 11. The connecting ring 13 is located between the outer cylinder 12 and the inner cylinder 11 and is fixed on the inner cylinder 11 and the outer cylinder 12. A plurality of air vents 131 are opened on the connecting ring 13 along the circumferential direction. The pen cap 1 is connected to the pen barrel 4 through a fastener 5. When the pen cap 1 is tightly closed, the pen head 2 extends into the inner cylinder 11, and the pen neck 3 is used to abut and cover the plurality of air vents 131. The pen neck 3 abuts against and blocks a number of vents 131, which helps to keep the watercolor paint or other liquid paint at the pen tip moist and prevent it from drying out. By designing the outer tube 12 and the vents 131 open at both ends, the ventilation area and ventilation flow rate can be increased after a child accidentally swallows it. Compared with other pen caps 1, it can provide a better ventilation effect, and at the same time, the vent holes are hidden in the pen cap 1, which increases the aesthetics.

1 to 4, the fastener 5 includes a first limiting protrusion 51 and a plurality of limiting protrusions 52. The first limiting protrusion 51 is formed by the pen holder 4 protruding outward in the circumferential direction. The plurality of limiting protrusions 52 are evenly distributed on the inner wall of the outer tube 12 along the circumferential direction. When the pen cap 1 is tightly closed, the plurality of limiting protrusions 52 are located on the side of the first limiting protrusion 51 away from the pen tip 2 and abut against the first limiting protrusion 51. The design of the first limiting protrusion 51 and the plurality of limiting protrusions 52 enables the pen cap 1 to be accurately guided and fixed on the pen holder 4 when it is tightly closed, thereby avoiding loss or damage due to looseness during carrying.

1 to 4, the pen barrel 4 is circumferentially outwardly protruded to form a second limiting protrusion 43, which is located at the rear end of the pen barrel 4. The rear end of the pen barrel 4 is provided with an annular step surface 44 for the pen cap 1 to abut against. The second limiting protrusion 43 is located on the side of the annular step surface 44 away from the pen tip 2. When the pen cap 1 is tightly covered on the rear end of the pen barrel 4, a plurality of limiting protrusions 52 are located between the second limiting protrusion 43 and the annular step surface 44, and the pen cap 1 abuts against the annular step surface 44. The design of the second limiting protrusion 43 and the annular step surface 44 enables the pen cap 1 to be accurately guided and fixed on the pen barrel 4 when it is tightly covered, avoiding loss or damage due to looseness during use.

1 to 4, the liquid storage cavity 42 is located on the side of the second step surface close to the pen head 2, and the tail end of the pen body 4 is a hollow columnar shape sealed near one end of the liquid storage cavity 42. The deformation capacity of the tail end of the pen body 4 can be increased by the sealed hollow columnar shape.

Referring to Fig. 1 to Fig. 4, a water reservoir 41 is fixed in the pen shaft 44, and the water reservoir 41 is located between the pen head 2 and the liquid storage chamber 42, and the water reservoir 41 is a spiral sheet structure. The spiral sheet structure includes a plurality of spacers 411, and the spacers 411 are close to the liquid storage chamber 42 and have a large spacer near the pen neck 3. The denser spacers 411 have a stronger capillary effect on the ink, and the sparser spacers 411 have a weaker capillary effect. When ink leaks, the denser spacers 411 are first adsorbed into the cavity formed by the spacers 411 through capillary action, thereby ensuring that the pen head 2 will not accumulate ink or leak ink.

Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
