Description

Segmented feedback eyeliner

Technical Field

The present application relates to the technical field of cosmetics, in particular to a cosmetic pen.

Background technique

Eyeliner is a pen-shaped cosmetic used to draw a fine line around the eye to highlight the eye contour and enhance the eye makeup effect.

In general designs, in order to avoid the difficulty of restoring the stress structure after the pen tip dries and the difficulty for users to adapt to the feel, a single structure is used as much as possible in the pen tip design.

However, with a single-structure eyeliner, it is difficult for beginners to control the weight, making it inconvenient to draw lines of different thicknesses. In addition, the ink at the tip of the eyeliner easily evaporates and condenses, affecting subsequent use.

Summary of the invention

The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the title of the invention of this application to avoid blurring the purpose of this section, the abstract of the specification and the title of the invention, and such simplifications or omissions cannot be used to limit the scope of the present invention.

In view of the above problems and/or the problems existing in the prior art, the present invention is proposed.

In order to solve the above technical problems, the present invention provides the following technical solutions:

The segmented hand-feel feedback eyeliner comprises a pen holder and a pen head connected to the pen holder, wherein the pen head comprises a capillary fiber rod and a pen tip arranged above the capillary fiber rod, and is characterized in that:

The pen tip comprises a sponge section, and a fiber pen tip is arranged above the sponge section;

The height of the sponge segment is 1-3 mm;

The fiber pen tip height is 0.5-1mm;

A pen cap is also provided on the pen barrel;

A sealing ring is provided at the connection between the pen holder and the pen cap, and the sealing ring is provided on one of the pen holder and the pen cap;

The pen cap is provided with a one-way valve with the conducting direction facing outwards;

An elastic air suction device is arranged on the upper part of the pen cap;

The elastic air suction device is provided with an exhaust extrusion end, and the exhaust extrusion end is arranged above the pen cap;

After the pen cap is covered on the pen barrel, it forms a closed space with the ink tank in the pen barrel;

The elastic air suction device is connected to the ink tank through the fiber structure of the pen tip;

The ink tank contains volatile ink;

After the pen cap is buckled onto the pen holder, the exhaust extrusion end is pressed to exhaust the elastic air suction device;

The elastic air suction device enters an elastic reset state, so that the air pressure in the pen cap is reduced, thereby promoting the volatile ink to evaporate into the pen cap and maintaining the wettability of the pen tip.

Firstly, the present invention optimizes the segmented tactile feedback eyeliner. After the optimization, an elastic air suction device and a one-way valve are arranged on the pen cap to reduce the air pressure in the enclosed space between the pen cap and the ink tank, thereby causing the volatile ink to evaporate into the pen cap and continuously maintain the wettability of the pen tip; secondly, the pen tip adopts a layered structure, the fiber pen tip will deform in a small range, providing a first layer of pressure feedback for the hand feel, and the sponge segment will deform in a larger range under more stress, providing a second layer of pressure feedback for the hand feel, which is easy to control and convenient for drawing lines of different thicknesses; finally, the fiber pen tip height is 0.5-1mm, and the sponge segment height is 1-3mm, which adapts to the eye contour and the user's hand strength habits, and provides a technical basis for maintaining the shape of the pen tip under various habitual stresses, presenting extremely orderly staged linear deformation.

Preferably, two pen tips are arranged above the capillary fiber rod, the heights of the two pen tips are consistent, and the distance between the two pen tips is 4-8 mm; the present invention optimizes the pen tip structure, and after the optimization, any one of the pen tips can be selected to draw eyeliner alone (the line is thinner), and two pen tips can be selected to be staggered and superimposed to draw eyeliner at the same time (the line is thicker), so as to draw eyeliner of different thicknesses, which is suitable for novices.

Preferably, the fiber pen tip is a fiber pen tip formed by multiple nylon fibers, and the cross-sectional diameter of the root of the fiber pen tip is 0.5-1mm; the present invention optimizes the pen tip structure, and the optimized nylon fiber pen tip is soft and delicate, very smooth to use, and has light hand feedback, providing a first layer of pressure feedback for the hand, and is used to draw thinner lines.

Preferably, the diameter of the sponge segment gradually decreases from the middle to the top, the material of the sponge segment is polyurethane, and the root diameter of the sponge segment is 1.5-3mm; the present invention optimizes the pen tip structure. After the optimization, the sponge segment is made of polyurethane material, so that the sponge segment is harder than the nylon fiber pen tip. When in use, the sponge segment will deform in a larger range when more stress is applied, providing a second layer of pressure feedback for the hand feel, which is used to draw thicker lines.

Preferably, a through hole matching the cross-sectional diameter of the fiber pen tip root is provided at the center of the sponge segment, and the fiber pen tip is installed in the through hole and connected to the capillary fiber rod; the fiber pen tip is directly connected to the capillary fiber rod through the through hole to make the fiber pen tip ink discharge smoother.

Preferably, the exhaust extrusion end is provided with a piston cooperating with the inner cavity of the pen cap and a spring for resetting the piston. When the exhaust extrusion end is pressed downward, the piston slides downward so that the air in the pen cap covered on the pen shaft is discharged from the one-way valve, and the spring resets the piston upward to slide so that the air pressure in the pen cap is reduced. The present invention optimizes the pen cap structure. After the optimization, the user naturally presses the exhaust extrusion end when tightening the pen cap. The piston in the exhaust extrusion end slides in the pen cap as the exhaust extrusion end is pressed to discharge the gas in the pen cap. The spring automatically resets the piston, so that the air pressure in the pen cap is reduced, which promotes the volatile ink to evaporate into the pen cap, thereby maintaining the wettability of the pen tip.

Preferably, the sealing ring is connected to the pen holder, and the sealing ring is made of rubber material; the rubber ring has good elasticity and can return to its original shape after being compressed to ensure the sealing effect, and the rubber ring is waterproof and corrosion-resistant and has a long service life.

Preferably, the pen cap is also provided with a pressure relief valve that is pushed vertically upward to open, and the pressure relief valve is provided with an elastic mechanism with downward elastic force, and the elastic mechanism resets the pressure relief valve that is pushed open; when the pen cap is opened, the pressure relief valve is first pushed open to release the enclosed space between the pen cap and the pen barrel, thereby preventing the air pressure from continuing to decrease when the pen cap is opened, thereby sucking out too much ink onto the pen tip and affecting use.

Preferably, the pen cap includes a pen cover located below and connected to the pen shaft, the height of the pen cover is 0.8-2.0 cm, and a one-way valve is arranged on the pen cover; an elastic suction device is arranged above the pen cover, and the elastic suction device adopts an elastic air bag; the hard pen cover is set to 0.8-2.0 cm, which not only ensures the firmness of the pen shaft, but also allows the user to naturally pinch the elastic air bag when taking the pen, rather than pinching the short pen cover. When the pen cap is tightened, the elastic air bag is naturally pinched, and the exhaust work is completed naturally, so that the user can naturally realize the function of the present invention even if he does not consider the special usage rules.

Example 1

1 to 3 , the present embodiment provides a segmented tactile feedback eyeliner including a pen body 1 and a pen head 3 connected to the pen body 1 , wherein the pen head 3 includes a capillary fiber rod and a pen tip 4 disposed above the capillary fiber rod.

The pen tip 4 includes a sponge section, and a fiber pen tip is arranged above the sponge section; the height of the sponge section is 1-3mm; the height of the fiber pen tip is 0.5-1mm; a pen cap 2 is also sleeved on the pen body 1; a sealing ring 6 is arranged at the connection between the pen body 1 and the pen cap 2, and the sealing ring 6 is arranged on one of the pen body 1 and the pen cap 2; the pen cap 2 is provided with a one-way valve 7 with a conducting direction facing outward; an elastic air suction device is arranged on the upper part of the pen cap 2; the elastic air suction device is provided with an exhaust extrusion end 5, and the exhaust extrusion end 5 is arranged above the pen cap 2; the pen cap 2 is covered on the pen body 1 After that, a closed space is formed with the ink tank in the pen body 1; the elastic air suction device is connected to the ink tank through the fiber structure of the pen head 3; the ink tank contains volatile ink; after the pen cap 2 is buckled on the pen body 1, the exhaust extrusion end 5 is pressed to exhaust the elastic air suction device; the elastic air suction device enters an elastic reset state, so that the air pressure in the pen cap 2 is reduced, thereby promoting the volatile ink to evaporate into the pen cap 2 and maintain the wettability of the pen head 3; the pen head 3 adopts a layered structure, and the fiber pen tip will deform in a small range, providing the first layer of pressure feedback for the hand feel, and the sponge segment When more stress is applied, the deformation will occur in a larger range, providing a second layer of pressure feedback for the hand feeling, which is easy to control and convenient for drawing lines of different thicknesses; secondly, an elastic air suction device and a one-way valve 7 are arranged on the pen cap 2 to reduce the air pressure in the closed space between the pen cap 2 and the ink tank, so as to promote the volatile ink to evaporate into the pen cap 2 and maintain the wettability of the pen head 3; finally, the pen body 1 has a fiber pen tip height of 0.5-1mm and a sponge section height of 1-3mm, which are adapted to the eye contour and the hand strength habits of the user, so as to provide a convenient way for the tip of the pen head 3 to be used in various habits. The shape is maintained under force, presenting an extremely orderly phased linear deformation, providing a technical basis. The one-way valve allows air to only go out from the pen cap 2. The elastic air suction device has a piston that cooperates with the inner wall of the pen cap 2, and a spring that resets the piston. When the pen cap 2 is covered on the pen body 1, when the exhaust extrusion end 5 is pressed, the piston pushes the air in the pen cap 2 to be discharged from the one-way valve 7, and the exhaust extrusion end 5 is released. The spring pushes the exhaust extrusion end 5 up and resets it, and the air pressure in the pen cap 2 is reduced, thereby prompting the volatile ink to evaporate into the pen cap 2 and maintain the wettability of the pen tip 3.

Two pen tips 4 are arranged above the capillary fiber rod, the heights of the two pen tips 4 are consistent, and the distance between the two pen tips 4 is 4-8mm; the present invention optimizes the structure of the pen tip 4, after which any one of the pen tips 4 can be selected to draw eyeliner alone (thinner lines), or two pen tips 4 can be selected to be staggered and superimposed to draw eyeliner at the same time (thicker lines), thereby drawing eyeliners of different thicknesses, which is suitable for novices.

The fiber pen tip is a fiber pen tip formed by arranging multiple nylon fibers, and the cross-sectional diameter of the root of the fiber pen tip is 0.5-1mm; the present invention optimizes the structure of the pen tip 4, and the optimized nylon fiber pen tip is soft and delicate, very smooth to use, and has light hand feedback, providing a first layer of pressure feedback for the hand, and is used to draw finer lines.

The diameter of the sponge section gradually decreases from the middle to the top. The material of the sponge section is polyurethane, and the root diameter of the sponge section is 1.5-3mm. The present invention optimizes the structure of the pen tip 4. After the optimization, the sponge section is made of polyurethane material, which makes the sponge section harder than the nylon fiber pen tip. When in use, the sponge section will deform in a larger range when more stress is applied, providing a second layer of pressure feedback for the hand feel, which is used to draw thicker lines.

Preferably, a through hole matching the cross-sectional diameter of the fiber nib root is provided at the center of the sponge segment, and the fiber nib is installed in the through hole and connected to the capillary fiber rod; the fiber nib is directly connected to the capillary fiber rod through the through hole to make the fiber nib ink discharge smoother.

When in use, if you want to draw thinner lines, use the fiber pen tip. At this time, the fiber pen tip made of nylon material provides the first layer of force feedback on the hand, so you can continuously draw thinner lines. If you need to draw thicker lines, you can use a little force and the polyurethane sponge segment will provide a second layer of force feedback. Users can quickly master the drawing of lines of different thicknesses according to the two layers of different feedback forces. Secondly, you can choose to overlap two pen tips 4 and draw eyeliner at the same time, so as to draw eyeliner of different thicknesses. Combining the fiber pen tip and the sponge segment can draw more delicate lines, which is more convenient to use. After use, put the pen cap 2 on the pen body 1, press the exhaust extrusion end 5 to exhaust part of the air from the one-way valve 7, and the elastic suction device reduces the air pressure of the pen cap 2 when it is elastically reset, so as to promote the volatile ink to evaporate into the pen cap 2 and maintain the wettability of the pen head 3.

Example 2

3 to 5 , a second embodiment of the present invention is shown, which is based on the previous embodiment.

The exhaust extrusion end is provided with a piston that cooperates with the inner cavity of the pen cap and a spring that resets the piston. When the exhaust extrusion end is pressed downward, the piston slides downward to discharge the air in the pen cap covered on the pen shaft from the one-way valve, and the spring resets the piston upward to slide to reduce the air pressure in the pen cap. When the user tightly covers the pen cap, the exhaust extrusion end is naturally pressed, and the piston in the exhaust extrusion end slides in the pen cap as the exhaust extrusion end is pressed to discharge the gas in the pen cap. The spring automatically resets the piston to reduce the air pressure in the pen cap, thereby causing the volatile ink to evaporate into the pen cap and maintain the wettability of the pen tip.

The sealing ring 6 is connected to the pen holder 1, and the sealing ring 6 is made of rubber. The rubber ring has good elasticity and can return to its original shape after being compressed to ensure the sealing effect. The rubber ring is waterproof and corrosion-resistant and has a long service life.

The pen cap 2 is also provided with a pressure relief valve 7 which is pushed vertically upward to open. The pressure relief valve 7 is provided with an elastic mechanism with elastic force downward, and the elastic mechanism resets the pressure relief valve 7 which is pushed open. When the pen cap 2 is provided with the pressure relief valve 7, the pressure relief valve 7 is pushed open first when the pen cap 2 is opened, so as to release the closed space between the pen cap 2 and the pen barrel 1, so as to prevent the pen cap 2 from continuing to reduce the air pressure when the pen cap 2 is opened and sucking out too much ink onto the pen tip 4 to affect the use. A spring is connected to the back of the pressure relief valve 7, so as to automatically reset and close the air release after the pressure relief valve 7 is pushed open.

When in use, after the pen cap 2 is covered on the pen body 1, the pen cap 2 and the ink tank in the pen body 1 form a closed space using the sealing ring 6. The exhaust extrusion end 5 is pressed to discharge part of the air from the one-way valve 7. The elastic suction device reduces the air pressure in the pen cap 2 when it is elastically reset, prompting the volatile ink to evaporate into the pen cap 2, maintaining the wettability of the pen tip 3, and preventing the pen cap 2 from falling off easily. When it is necessary to open the pen cover, first push the pressure relief valve 7 to release the negative pressure in the ink tank in the pen cap 2 and the pen body 1, so that the pen cap 2 can be removed more smoothly. At the same time, when the pen cap 2 is opened, the air pressure will not continue to be reduced to suck out too much ink onto the pen tip 4, which will affect the subsequent use.

Example 3

This is the third embodiment of the present invention, and is based on the above two embodiments.

The pen cap 2 includes a pen cover located below and connected to the pen body 1, the height of the pen cover is 0.8-2.0 cm, and a one-way valve is set on the pen cover; an elastic suction device is set above the pen cover, and the elastic suction device adopts an elastic air bag; the hard pen cover is set to 0.8-2.0 cm, which not only ensures the firmness of the pen body 1, but also allows the user to naturally pinch the elastic air bag when taking it, instead of pinching the short pen cover. When the pen cap is tightened, when the elastic air bag is naturally pinched, the exhaust work is completed naturally, so that even if the user does not consider the special usage rules, the function of the present invention can be naturally realized.
