Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1:

referring to fig. 1 and 2, for the utility model discloses a leak protection type cosmetic pencil nib, including nib seat 1, the intermediate position of nib seat 1 is provided with the dead slot, and the dead slot is used for installing spring holder 5 and piston bush 3, and the excircle of spring holder 5 and the interior circle sliding connection of piston bush 3 are provided with spring 4 in spring holder 5, and spring 4's one end butt is in spring holder 5, and spring 4's the other end is contradicted with piston bush 3 and is connected. The pen holder base 1 is provided with a bulge 13 at one side close to the liquid outlet 11, the bulge 13 is buckled with a groove 23 arranged on a fixed claw 52, so that the fixed claw 52 is fixed on the pen holder base 1, the other end of the fixed claw 52 is fixedly connected with a spring seat 5, the spring seat 5 and a piston sleeve 3 are fixed in a hollow groove of the pen holder base 1 through the fixed claw 52, and a liquid passing groove 51 is arranged between the fixed claws 52.

Referring to fig. 3 and 4, the outer wall of the pen holder seat 1 is provided with a fixing block 9, the fixing block 9 is fixedly connected with the solution pipe 8, and after the solution in the solution pipe 8 is used up, the fixing block can be detached for replacement, so that the pen holder seat 1 can be recycled.

Referring to fig. 4 and 5, in the case that the piston sleeve 3 is not under the pressure of the solution, the piston sleeve 3 and the rear cover 2 are abutted against each other to form a mechanical seal, and the solution in the solution pipe 8 cannot enter the empty groove of the pen point seat 1. When the piston sleeve 3 is under the pressure of the solution, the liquid in the solution tube 8 generates a flow force, the flow force acts on the excircle of the top end of the piston sleeve 3, the force on the piston sleeve 3 enables the spring 4 to move towards the pen point device 6, the piston sleeve 3 is separated from the rear cover 2, and the solution flows into the pen head seat 1 from the space between the piston sleeve 3 and the rear cover 2 through the rear cover hole 21. The solution flowing into the pen head seat 1 flows into the liquid outlet hole 11 of the pen head seat 1 through the liquid through tank 51, and finally flows into the middle of the pen head device 6. The inner wall of the other end of the pen holder seat 1 is provided with a clamping groove 12, the rear cover 2 is provided with a lug 22, the clamping groove 12 is buckled with the lug 22 together, so that the rear cover 2 is fixed on the pen holder seat 1, and the rear cover 2 can prevent the spring seat 5 arranged in the middle of the pen holder seat 1 and the piston sleeve 3 from being separated from the pen holder seat 1.

Referring to fig. 2, the leakproof cosmetic pencil tip is set to be the soft rubber tip 61, the soft rubber tip 61 can be made of two different materials, the two materials have different melting points and are subjected to two-time injection molding, the soft rubber tip 61 can be directly fixed with the pencil tip seat 1, the common cosmetic pencil tip device 6 can be made of animal hair, people who are in the cosmetic process are allergic to the animal hair, the pencil tip device 6 is set to be the soft rubber tip 61, people can be prevented from being allergic to the animal hair, and meanwhile the soft rubber tip 61 is cleaned well.

The implementation principle of the embodiment is as follows: solution produces under the effect of external force and flows, flow force acts on behind piston housing 3, piston housing 3 presses spring 4 to make spring 4 move down, solution flows into in the nib seat 1 from between piston housing 3 and the back lid 2, through the logical liquid groove 51 between the stationary dog 52, it flows to in the middle of the nib 6 to get into liquid hole 11 at last, the outer end sphere of piston housing 3 gets under the effect of spring force and the sphere contact of back lid 2 after external force stops, spring 4 restores the normal position, the excircle of piston housing 3 and the contact of back lid 2 play sealed effect, solution no longer continues to get into the dead slot, avoid solution to leak outward when not using.

Example 2:

the difference from the embodiment 1 is that: referring to fig. 4, the nib device 6 is provided as a bristle 62, and the bristle 62 is fixedly connected with the nib holder 1 by the brush sleeve 7. The pen point is set 6 to be the brush head 62, and the brush head 62 is not hydrophilic or grease, and is easy to clean, and is not easy to deform, and when the brush head 62 needs to be replaced due to overlong service time, the brush head 62 fixed by the brush sleeve 7 is convenient to detach and install.

The implementation principle of the embodiment is as follows: solution produces under the effect of external force and flows, flow force acts on behind

piston sleeve

3, 3 pressing spring 4 of piston sleeve make spring 4 downstream, solution flows into the inner chamber of pen point seat 1 through back lid hole 21, it is middle to get into out liquid hole 11 and flow to nib 6 through the logical liquid groove 51 between the stationary dog 52 at last, external force stops the outer end sphere of back piston sleeve 3 and the sphere contact of back lid 2 under the effect of spring force, spring 4 restores the normal position, the excircle of piston sleeve 3 and the contact of back lid 2 play sealed effect, solution no longer continues to get into the dead slot in, avoid solution to leak outward when not using.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
