Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for spraying a heated liquid on hair for hair growth and maintenance.

[0002]

2. Description of the Related Art FIG. 1 shows the configuration of a conventional apparatus. A flexible compressed air supply pipe (1) for generating foam and a foamed hair growth liquid are provided above a transparent container (4) containing a liquid having a hair growth effect (hereinafter referred to as hair growth liquid). Is fitted with a lid (5) fitted with a foam release pipe (3) for spraying on the hair. The entire container (4) equipped with the lid (5) is inserted into a heater (8) using a separate electric heater as a heat source to warm the hair growth solution inside the container (4). In use, the air from the air compressor (6) is sent to the compressed air supply pipe (1) of the essential device (4) taken out of the heater (8). The lower end of the compressed air supply pipe (1) is inserted close to the bottom of the container (4) and enters the hair growth liquid. When the compressed air is sent, bubbles are generated in the container (4). The foam exits through a foam discharge pipe (3). The outlet of the foam discharge pipe (3) is brought close to the hair, and a foamy hair growth solution is sprayed on the hair.

[0003]

This has the following disadvantages. (A) Since the hair growth solution was heated by inserting it into a separate heater, the space between the heater and the container made it difficult to heat the hair growth solution, resulting in poor thermal efficiency. (B) The liquid temperature fluctuated depending on the amount of liquid in the container. (C) When applying the hair growth solution to the hair, a container with a pipe is held by hand, so that if the entire container is made heavy, the usability will deteriorate. For this reason, the amount of the hair growth solution in the container is limited to about 200 CC. Therefore, as the frequency of spraying increases, the number of times of replenishing the hair growth solution to the container increases, and the handling is troublesome.

[0004]

Means for Solving the Problems Container (4) for storing hair growth liquid
In the middle of the liquid supply pipe (10) leading to the discharger (2) for discharging bubbles with compressed air, a heater (8) having a temperature control function and a valve (19) for preventing return of the liquid are provided. The present invention is a hair spraying device having the above configuration.

[0005]

Embodiments of the present invention will be described below. In the present invention, the device configuration shown in FIG. 2 is used.
A hair growth solution supply path is formed from the container (4) containing the hair growth solution through the liquid supply pipe (10) to the nozzle (13) and the discharger (2) having the bubble discharge opening (16). In the middle of the liquid supply path, a check valve (19) for opening and closing the passage of the liquid supply pipe (10) An electric heater (14) for heating the hair growth liquid
And a heater (8) provided with a temperature sensor (15). A compressed air supply pipe (1) for sending compressed air from the air compressor (6) is connected to the nozzle (13).
The electric motor (11) for driving the air compressor (6) is pressurized by the power supply (20) when the switch (18) is closed. A temperature controller (9) for controlling temperature control of the heater (8) uses a power source (20) as a power source and a temperature sensor (1).
The voltage of the electric heater (14) is controlled by the signal of 5) to keep the temperature constant. The operation of the apparatus having the above-described device configuration will be described below. Press the switch (18) to start the motor (11) and move the air compressor (6). When the compressed air from the air compressor (6) is sent to the nozzle (13), the tip of the nozzle (13) is thinned, so that the flow velocity of the air is increased. For this reason, the air pressure around the nozzle tip in the discharger (2) becomes lower than the atmospheric pressure, and the hair growth liquid stored in the container (4) is pushed to the atmospheric pressure and is supplied to the liquid supply pipe (1).
0), is sucked into the discharger (2) through the check valve (19) and the heater (8). The hair growth liquid that has reached the discharger (2) is foamed by the air blown out from the tip of the nozzle (13) and jumps out of the opening (16). When the switch (18) is opened, the electric motor (11) and the air compressor (6) stop,
The air pressure at the tip of the nozzle (13) also returns to atmospheric pressure. Without the check valve (19), the hair growth liquid in the liquid supply pipe (10) and the heater (8) returns to the container (4). In order to prevent this return, a check valve (13) is provided to close the hair growth solution passage. The hair growth liquid below the check valve (19) returns to the container (4), but the hair growth liquid above the check valve (19) does not return. By this action, the hair growth liquid stored in the heater (8) is continuously heated to maintain an appropriate temperature, and waits until the next use. FIG. 3 shows another embodiment. In FIG. 3, a solenoid valve (12) is used instead of the check valve in the device configuration shown in FIG. Nozzle (1) is passed from the container (4) storing the hair growth solution through the solution supply pipe (10).
A supply channel is provided for the hair growth liquid reaching the discharger (2) with 3) and a bubble discharge opening (16). An electromagnetic valve (12) for opening and closing the passage of the liquid supply pipe (10), an electric heater (14) for heating the hair growth liquid, and a temperature sensor (1) in the middle of the supply path.
A heater (8) with 5) is provided. The nozzle (1
3) is connected to a compressed air supply pipe (1) for sending compressed air from the air compressor (6). When the switch (18) is closed, the electric motor (11) for driving the air compressor (6) and the operating coil of the solenoid valve (12) are pressurized by the power supply (20). A temperature controller (9) for controlling the temperature of the heater (8) uses a power supply (20) as a power source, and controls the voltage of the electric heater (14) by a signal from the temperature sensor (15) to keep the temperature constant. keep. The operation of the apparatus having the above-described device configuration will be described below. Press the switch (18) to start the motor (11) and move the air compressor (6). Also, the solenoid valve (12) is pressurized to open the passage for the hair growth solution. The compressed air from the air compressor (6) is
When the air is sent to 3), the tip of the nozzle (13) becomes thin, and the flow velocity of the air becomes high. For this reason, the air pressure around the nozzle tip in the discharger (2) becomes lower than the atmospheric pressure, and the hair growth liquid stored in the container (4) is pushed to the atmospheric pressure, and the liquid supply pipe (10) and the electromagnetic valve (12) ), Is drawn through the heater (8) into the discharger (2). The hair growth liquid that has reached the discharger (2) is foamed by the air blown out from the tip of the nozzle (13) and jumps out of the opening (16). Switch (1
When 8) is opened, the electric motor (11) and the air compressor (6) stop, and the air pressure at the tip of the nozzle (13) also returns to the atmospheric pressure.
If left as it is, the hair growth liquid in the liquid supply pipe (10) and the heater (8) returns to the container (4). To prevent this return, when the switch (18) is opened, the solenoid valve (12) is demagnetized to close the passage for the hair growth solution. The hair growth liquid below the solenoid valve (12) returns to the container (4), but the hair growth liquid above the solenoid valve (12) does not return. By this action, the hair growth liquid stored in the heater (8) is continuously heated to maintain an appropriate temperature, and waits until the next use. The solenoid valve (12) can make the liquid passage resistance inside the valve smaller than that of the check valve, and is an effective method when the pressure around the nozzle tip in the discharger is small and the suction of liquid is weak. Next, an embodiment of a method of combining the discharger (2) and the heater (8) will be described. FIG. 4 shows one embodiment. Discharger (2) in sprayer (17) large enough to hold with one hand

A flexible electric heater (7) such as a silicon rubber heater having a foil-shaped element or the like as a heating element is wound around the liquid supply pipe (10), and the liquid is heated while having flexibility as a pipe. . Since both the liquid supply pipe (10) and the compressed air supply pipe (1) around which the flexible electric heater (7) is wound are flexible, the sprayer (17) is held by hand and the discharger (2) It is easy to bring the opening close to the hair, and the switch (18) is pressed to spray the hair growth solution. In the drawing, the wiring of the switch (18), the electric wiring of the flexible electric heater (7), the temperature sensor (7) and the wiring thereof are not shown. FIG. 5 shows another embodiment. A heater (8) with a discharger (2) and a switch (18) and an electric heater (14) is built in a sprayer (17) sized to be held by one hand. The liquid supply pipe (10) is connected to the heater (8) in the sprayer (17), and the compressed air supply pipe (1) is connected to the discharger (2). The hair growth liquid supplied through the liquid supply pipe (10) is heated by the heater (8). It is easy to hold the sprayer (17) by hand and bring the opening of the discharger (2) closer to the hair, and press the switch (18) to spray the hair growth liquid. In the drawing, the wiring of the switch (18), the electric wiring of the electric heater (14), the temperature sensor (15), and the wiring are not shown. In the above description, the hair growth liquid is used as the liquid, but the present invention can be applied not only to the hair growth liquid but also to a liquid whose efficacy is improved by warming when spraying, such as a cleaning liquid.

[0006]

According to the present invention, it is possible to directly heat the amount of hair growth liquid that is found in one use, so that a stable liquid temperature can be maintained. (B) Since the hair growth solution is sucked up, the hair growth solution can be supplied directly from a large-capacity container, and the labor for replenishing the hair growth solution can be omitted.
