Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a brush, especially to a drop-shaped brush head assembly with an inclined cutting plane.

Description of Related Art

A brush available on the market includes a flat surface on top thereof and a bundle of bristles is disposed over a holder. The operating angle of the brush is difficult to control while using the brush to paint tiny area. Moreover, the bristles are collected in a bundle so that a paint discharged from a discharge hole flows along the bristles. However, the bristles are closely attached to each other. Thus the bristles hold more amount of the paint through capillary action while applying the paint with the brush. Besides the increased amount of the paint required, the paint left in the bristles has to be cleaned frequently. Thus there is room for improvement and there is a need to provide a novel structure of the brush head assembly.

SUMMARY OF THE INVENTION

Therefore it is a primary object of the present invention to provide a drop-shaped brush head assembly which is convenient to use. A paint is applied smoothly. Moreover, the angle of the drop-shaped brush head assembly is easy to control and the brush stroke is smooth.

It is another object of the present invention to provide a drop-shaped brush head assembly that includes bristles not only able to reduce the capillary action, but also having good recovery and elasticity.

It is a further object of the present invention to provide a drop-shaped brush head assembly which provides a constant and uniform amount of paint being discharged.

It is further object of the present invention to provide a drop-shaped brush head assembly which allows paints therein to flow in the single direction.

In order to achieve the above objects, a drop-shaped brush head assembly according to the present invention includes a drop-shaped brush head formed by a plurality of bristles used for combing hair and a handle for support connected to each other. A plurality of discharge holes is disposed on top of the handle and a mounting space formed in the handle. A paint in the mounting space passes through the discharge holes and comes out of the handle to be applied to an area users intend to paint by the top of the respective bristle. The water drop design of the brush head has a pointy end on top and a larger end on bottom thereof. The pointy end allows users to control the operating angle easily while grooming fine-hair area and the larger end is used to apply the paint to large area conveniently. Thereby the brush head is more convenient and easier to use and the paint is applied smoothly.

A circular abutting member is set around the handle and used for allowing the drop-shaped brush head to abut against an inner wall of a container.

The bristle is composed of an elastic tapered cylinder and a curved head formed on top of the cylinder. The bristles are arranged at a top surface of the handle with the same interval between the two adjacent bristles. Besides reduction of the capillary action, the deformation of the bristle with elasticity is minimized and the recovery of the bristle after brushing is enhanced.

A middle part of the top surface is a curved surface projecting a bit from the plane while the height of the respective bristles is decreased from the center to the edge of the top surface. Thereby the bristles near the center of the top surface can be closely attached to the area users intend to paint. The bristles on the periphery of the top surface are in contact with other area once the drop-shaped brush head assembly is inclined at a little angle.

The top surface is drop-shaped with a pointy end on the upper side and a larger end on the lower side. The discharge holes are not distributed uniformly. Instead, they are concentrated at the center and decreased with the distance from the center of the top surface.

A piston rod is mounted in the mounting space of the drop-shaped brush head. The piston rod is connected to a sleeve and an elastic member is disposed between the piston rod and the sleeve. Thus the drop-shaped brush head assembly is movable in the axial direction. At least one discharge hole is radially passed through the sleeve and located close to the bottom of the sleeve. A non-return film is covered the discharge opening for backflow prevention. Thus the paint will not flow backwards once entering the sleeve. The non-return film is designed to allow the flow only in one direction and protect the paint from contamination caused by the backflow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Refer to FIG. 1 and FIG. 2; a drop-shaped brush head assembly with an inclined cutting plane (oblique section plane) is revealed. The drop-shaped brush head assembly includes a drop-shaped brush head 10, a hollow piston rod 20, and a hollow sleeve 30. A mounting space 142 is arranged at the drop-shaped brush head 10 and the hollow piston rod 20 is mounted in the mounting space 142. The piston rod 20 includes a leaning portion 21, a rod body 22 extended from one end of the leaning portion 21 and a fixing portion 23 extended from and arranged at the other end of the leaning portion 21. The hollow sleeve 30 is mounted on the rod body 22 of the piston rod 20 and an elastic member 40 is disposed between the piston rod 20 and the sleeve 30. The sleeve 30 consists of a shaft body 31, a conical bottom portion 33 tapered from one end of the shaft body 31, a circular flange 32 extended outward and arranged at the other end of the shaft body 31, at least one discharge opening 34 radially passed through the conical bottom portion 33 and a non-return film 35 covered the discharge opening 34.

Refer to FIG. 3 and FIG. 4, the drop-shaped brush head 10 is composed of a plurality of bristles 12 used for grooming hair and a handle 14 for support connected to each other. Each of the bristle 12 is composed of an elastic tapered cylinder 121 and a curved head 122 formed on top of the tapered cylinder 121. A circular abutting member 144 that abuts is set around a lower end of the handle 14. The bristles 12 are arranged at a top surface 141 of the handle 14 with the same interval between the two adjacent bristles 12. Besides reduction of the capillary action, the deformation of the bristle with elasticity is minimized and the recovery of the bristle after arranging is enhanced. The top surface 141 is a drop-like sloping surface. Refer to FIG. 5 and FIG. 6, the mounting space 142 is formed in the handle 14 under the top surface 141 while a plurality of discharge holes 143 is disposed on the top surface 141 and communicating with the mounting space 142.

The drop-shaped brush head 10 can be made from flexible plastic material. The bristles 12 and the handle 14 are integrally formed by machines.

Refer to FIG. 4, the top surface 141 of the drop-shaped brush head 10 looks like a water drop having a pointy end on top and a larger end on bottom thereof. The pointy end on top of the top surface 141 allows users to control the operating angle easily while grooming fine-hair area. The larger end on bottom of the top surface 141 is used to apply a paint to large area conveniently. Thereby the drop-shaped brush head 10 is more convenient to use and the paint is applied smoothly.

The discharge holes 143 in FIG. 4 are not distributed uniformly. They are concentrated at the center and decreased with the distance from the center of the top surface 141. For constant and uniform discharge of the paint, the number of the discharge holes 143 is directly proportional to the surface area of the top surface 141. In other words, the larger the surface area of the top surface 141, the more the number of the discharge holes 143.

As shown in FIG. 4 and FIG. 5, the height of the bristles 12 of the drop-shaped brush head 10 is decreased from the center to the edge of the top surface 141. Refer to FIG. 5, a middle part of the top surface 141 (a middle part of the oblique section plane) is a curved surface projecting a bit from the plane. Thereby the bristles 12 near the center of the top surface 141 can be closely attached to the area users intend to paint. Then the drop-shaped brush head assembly is inclined at a little angle to make the bristles 12 on the periphery of the top surface 141 contact other area. The angle of the brush head assembly is easy to control and the brush stroke is smooth. Moreover, while the user uses the brush head assembly to paint a large-surface area, the curved surface of the stop surface 141 is firstly in contact with the area and the paint over the curved surface is coated on the area. Thus the amount of the paint retained is reduced.

Refer to FIG. 5, the shape of the mounting space 142 is corresponding to the inclined tapered shape of the handle 14. As shown in FIG. 6, the discharge holes 143 are communicating with the mounting space 142.

Refer to FIG. 2, FIG. 5 and FIG. 7, the drop-shaped brush head 10 is connected to one end of a container 50 with a paint therein. By the circular abutting member 144, the drop-shaped brush head 10 abuts against an inner wall of the container 50. The container 50 can be a bottle, a pen or a flexible tube, provided with a cap 52. When the cap 52 is rotate and removed, the elastic member 40 provides an elastic force to make the piston rod 20 move upward for driving the drop-shaped brush head 10 to move. At the same time, the paint in the container 50 passes through the discharge opening 34 and the non-return film 35, and enters the sleeve 30. Then the paint keeps moving through the piston rod 20, the mounting space 142 in the drop-shaped brush head 10 and the discharge holes 143 of the handle 14 and then comes out of the drop-shaped brush head 10 to be evenly distributed on the bristles 12. Thus users can apply the paint to the area he/she intends to paint by the top of the respective bristle 12. The drop-shaped brush head 10 can be used to arrange any body hair (such as eyebrow or head hair) for multiple purposes such as beautification, coloring, or treatment.
