Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a hair styling brush that is equipped with a foam hair styling product injector and can spray and fill the brush bristles with foamy hair styling product during hair styling.

``Prior art'' This type of brush has a liquid passageway for the foam hair styling product that leads to the outside in the brush base, and a large number of small holes for ejection in the base on which the brush bristles are planted. A foam hair styling product from a known injector connected to the base end of the substrate is ejected from a group of small ejection holes to fill the brush bristles through a liquid passage.

``Problem that the invention attempts to solve'' This type of brush is extremely convenient because it allows you to style your hair without getting your hands dirty with hair styling products.
Since the force of the bubbles from the injector is attenuated as the distance increases, the amount of bubbles ejected from the group of small injection holes is not uniform, and there is a disadvantage that the bubbles are concentrated on the brush bristles near the injector.

The object of the present invention is to obtain an improved hair styling brush that can substantially equalize the amount of ejection from each ejection hole regardless of the distance from the injector.

``Means for Solving the Problems'' The hair styling brush of the present invention includes an injector 1 that injects foamy hair styling products from the nozzle 5 when the nozzle 5 protruding from the top is pushed down, and brush bristles 6 on one side. A storage hole 8 is provided vertically inside the substrate 7 on which brush bristles are planted, and the storage hole 8 is provided vertically in the substrate 7 for brush bristles 6.
The brush main body 2 is fitted to the top of the injector 1 with a lower mounting part 10, and the nozzle 5 has a push-down lever 11 on one side. Short cylindrical operation member 3 connected in communication
It has a long cylindrical shape, and its lower end is connected to the operating member 3.
The spring 13 is fluid-tightly connected and slidably fitted into the storage hole 8, and one side has a corresponding group of 12 small holes for ejection communicating with the 9 groups of small holes. The 12 groups of small holes that are pushed down by the slide cylinder 4 are shifted from the 9 groups of small holes.

"Function" In the above, the slide tube 4 is normally operated as shown in Figure 1.
is pushed down by the spring 13, and the position of the 12 groups of small jetting holes in the slide cylinder 4 is shifted vertically from the 9 groups of small jetting holes on the substrate 7 side, so that any small hole group 9,
12 is also in a sealed state.

In this state, when styling hair, the lever 11 is pushed down, thereby pushing down the nozzle 5 to open the discharge valve of the injector 1, and the hair styling product is injected from the nozzle 5 in the form of foam.

In this case, at the beginning of injection, each small hole group 9, 12 is in a state of being disconnected and sealed, so that the bubbles are not ejected to the brush bristles 6, and therefore the injected bubbles are not ejected to the slide tube 4.
When the bubbles are gradually accumulated in the inside and become almost full, the pressure of the extruded bubbles overcomes the pressing force of the spring 13 and pushes the slide cylinder 4 upward, so that the small holes 12 group and the small hole 9 group The positions of the holes match and communicate with each other, and bubbles are ejected from each of these small holes in substantially equal amounts, so that the brush bristles 6 are uniformly filled without any deviation.

``Example'' The hair styling product injector 1 is very well known, and the present application is not related to this injector itself, so to briefly explain it, this injector 1 is designed to inject liquefied gas into a can container housing a liquid hair styling product. This is a so-called aerosol-type product that has a built-in cylinder to increase the internal pressure.It has a built-in member that converts the injection liquid into a foam, and when the nozzle 5 is pushed in, the discharge valve opens and the spray is released. The hair styling product is converted into foam and is injected from the nozzle 5.

The brush body 2 includes an upright and elongated plate-shaped substrate 7.
It has a shape in which a bowl-shaped mounting part 10 is provided at the lower end, and the engaging protrusion 14 on the inner periphery of the lower end of the mounting part 10 is fitted into the constriction 15 on the outer surface of the top of the injector 1 to fix it. One side of 10 is cut out. The 9 groups of small jetting holes are provided in a nozzle-like protrusion,
Further, the storage hole 8 is opened at the upper end, and the opening at the upper end is closed with a stopper 17.

The operating member 3 has a narrow upper outer diameter, and the upper half including this narrow portion is fluid-tightly inserted into the lower end of the storage hole 8 of the substrate 7, and the push-down lever 1 on one side
1 is located in the notch 16 of the mounting portion 10.

The slide tube 4 has an inward periphery 18 at its lower end, and this periphery 18 is liquid-tightly fitted to the outer surface of the slim part of the upper part of the operating member 3, and the nozzle 5 is inserted through the member 3.
Further, a vertical strip 19 is provided protruding from one side of the outer surface, and this vertical strip 19 is engaged with a vertical groove 20 on one side of the inner surface of the substrate 7 to prevent rotation within the storage hole 8. That is, the 12 groups of small holes for ejection are assembled so as not to be displaced in the lateral direction with respect to the 9 groups of small holes.
The spring 13 is coil-shaped and is inserted between the top surface of the slide tube 4 and the back surface of the stopper 17.

Each of the above parts is molded and manufactured from synthetic resin material.

"Effect of the invention" As mentioned above, the present invention has the advantage that the substrate 7 of the brush body 2
A liquid passage that communicates 9 groups of small holes for ejection of the brush bristles 6 and the nozzle 5 of the hair styling product injector 1 is provided in the substrate 7 and has 12 groups of small holes that communicate with the 9 groups of small holes. The slide tube 4 is normally pressed down by a spring 13 to shift the positions of the small hole groups 9 and 12 and seal them. When the inside of the slide tube 4 is filled, it overcomes the spring 13 and pushes the slide tube 4 upward, allowing the small hole groups 9 and 12 to communicate with each other, so that the foamy hair styling product is distributed uniformly without being concentrated on the 6 parts of the brush bristles. It is possible to provide a hair styling brush that can be filled with injection.
