Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair growth cap for growing hair.

[0002]

2. Description of the Related Art As a conventional hair restoring method, a hair restoring agent is sprayed on the head and massaged with a finger to penetrate the hair root, or the hair restoring agent is sprayed on the head and then struck with a brush or the like. There is known a method of infiltrating the hair root while giving a stimulus to the scalp. However, in the above-mentioned hair growth method, even if a hair growth agent is sprayed on the head, it is difficult to uniformly spray the hair on the head, and it is also difficult to sufficiently penetrate the hair roots. Therefore, there is a drawback that the effect cannot be sufficiently exerted even when stimulation is given by tapping with a finger massage or brush.

On the other hand, put a helmet on the head,
A hair-growing method for growing the head by supplying a washing liquid, a hair-growing liquid, or the like between the helmet and the head is known.

[0004]

However, in the helmet used in this method, the helmet itself is made of a rigid body such as metal, while the outer diameter of the head is between the helmet opening edge and the side of the head. It was sealed with a smaller-diameter elastic seal cover. In such a helmet, since the diameter of the seal cover is smaller than the outer diameter of the head, mounting the helmet is troublesome. In addition, since the seal portion made of the elastic body always seals between the opening edge of the helmet and the head, it is impossible to activate or release the seal between the helmet and the hair-growing process according to the washing process or the hair-growing process. In addition, since the helmet is rigid, when the space between the helmet and the head is evacuated or supplied with air, the pressure difference causes the helmet to move up and down. It becomes difficult to seal between them. Further, there is a drawback that the inner wall of the helmet comes into contact with the scalp during the evacuation, and the washing solution, the hair growth solution and the like are not sufficiently distributed.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to uniformly distribute steam, a hair restorer, and the like to the entire scalp, to stimulate the scalp and to enhance a massage effect, An object of the present invention is to provide a hair growth cap that can be easily mounted on a cap and can easily select any of a sealed state and an open state of a peripheral seal portion.

[0006]

In order to achieve the above object, a hair growth cap according to the present invention is formed in a pot-like and flexible cap body, and is formed inside the cap body by protruding inward. A peripheral seal portion having a number of protrusions formed therein and a ring provided at the opening edge portion of the cap body and having a cavity through which air can be supplied, and inward by introducing air into the cavity. It is characterized by including a peripheral sealing portion that bulges toward the side of the head and seals closely to the side surface of the head, and a port provided in the cap main body for allowing fluid to flow in and out of the cap main body. Further, the inner diameter of the peripheral edge seal portion is formed to be larger than the outer diameter of the side surface of the head so that a gap can be secured between the peripheral seal portion and the side surface of the head in a natural state where air is not supplied to the cavity. It is characterized by being. Further, the peripheral seal portion operates so as to seal the space between the head and the cap main body only when the airtight state is required for the space formed between the head and the cap, and otherwise to open. Features. Further, the peripheral seal portion is provided with a ring-shaped member fitted to the outer periphery of the peripheral seal portion. The cavity formed in the peripheral seal portion for introducing air is formed in an annular upper and lower two stages. The projections include an inner projection provided around the port and an outer projection provided outside the inner projection. The inner projection presses the head during vacuum pressurization, but otherwise presses the head. The outer projection is provided so as to be in contact with the head even at times other than the time of vacuum pressurization. In addition, a chin belt is provided at a lower portion of the cap body to prevent the cap body from rising. Further, a cap cover for covering the cap body is provided outside the cap body.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a hair growth cap according to the present invention will be described in more detail with reference to the drawings showing an embodiment. FIG. 1 shows an embodiment of a hair growth cap according to the present invention. The hair growth cap 11 has a pot-shaped cap body 13. The cap body 13 is made of silicone rubber, and a port 15 made of metal fittings is provided on the top. The port 15 is configured to inject steam, a hair restorer, and pressurized air between the cap body 13 and the head H, and to suck air inside the cap body 13.

Further, an annular peripheral seal portion 17 is provided at the lower end opening edge of the cap body 13. The peripheral seal portion 17 is formed in the annular cavity 1 into which air is introduced.
9. Another port 21 is connected to the annular cavity 19, and air is introduced from the port 21 into the annular cavity 19. Then, by introducing air into the annular cavity 19, the peripheral seal portion 17 is bulged inward as shown in FIG. 2 so that the space between the peripheral seal portion 17 and the head H is sealed. Has become. Since the inner diameter D of the peripheral seal portion 17 in the natural state where air is not supplied is set to be slightly larger than the outer diameter d of the head H, there is no gap between the peripheral seal portion and the head H in the natural state. A gap t is created. By doing so, the hair growth cap 11 can be easily attached. In addition, it is possible to select whether to seal between the peripheral seal portion 17 and the head H or to make the head H open, depending on whether or not the peripheral seal portion 17 is operated. , Can be operated optimally. That is, the space between the peripheral seal portion 17 and the head H is sealed only when the airtight state is required, and the other portions are opened. Therefore, it is possible to prevent the head from being tightened for a long period of time and thereby to prevent the head from being hurt. For example, during the steam cleaning of the head described later, the cleaning steam introduced from the port 21 can be discharged to the outside through the gap t.

At the lower end of the peripheral edge seal portion 17, there is provided a folded portion 23 which is folded upward from the lower end. An annular metal belt 25 is disposed between the folded portion 23 and the peripheral seal portion 17. The metal belt 25 prevents the peripheral seal portion from bulging outward when air is sent to the cavity 19 of the peripheral seal portion 17, and bulges only inward to form a gap between the head H. Is strongly sealed.

On the other hand, a large number of projections 27 are formed on the inner surface of the flexible cap body 13. The tip of the projection 27 is formed in a hemispherical shape. When the hair growth cap 11 is put on the head H, a space 33 is secured between the cap body 13 and the scalp. It can come into contact with the scalp.
Therefore, when injecting steam, a hair restorer or the like into the cap body 13, it is possible to prevent the steam, the hair restorer, or the like from spreading sufficiently over the entire scalp, thereby preventing the hair growth effect from becoming uneven. When the air in the cap body 13 is sucked through the port 15, the flexible cap body 13 is pushed toward the head H by the atmospheric pressure, and the hemispherical projection 2 is pressed.
7, ... can press the scalp of the head H to give a stimulus and massage the scalp. further,
When evacuation is performed, the projection 27 is pressed toward the head because the cap body 13 has flexibility.
For this reason, since the cap main body 13 is supported, the peripheral seal portion 17 is not moved in the vertical direction, and the seal between the peripheral seal portion 17 and the head H can be reliably ensured.

Outside the cap body 13, a metal outer cap 29 is provided. Only the upper part of the outer cap 29 is fixed to the port 15, and the lower end can freely move up and down with respect to the metal belt 25 and the peripheral seal part 17. A pair of chin belts 30 is fixed between the metal belt 25 and the lower end of the cap body 13. The chin belt 30 is detachably tightened at the chin, thereby preventing the cap body 13 from rising due to vacuum suction during the vacuum pressurizing step and the chemical solution step.

The hair-growing cap 11 having such a configuration is used by being connected to a hair-growing device 31 as shown in FIG. Hereinafter, a hair growth method in the hair growth device 31 using the same will be described.

First, the head is washed with a surfactant or the like and completely dried, and then the hair growth cap 11 is put on the head H. Then, in the cap body 13 put on the head,
0 ° C steam is supplied for 3 minutes. This steam is mixed with ozone. This step can be set for 1 minute to 99 minutes. This promotes blood circulation, widens the pores, and loosens the coating layer formed in the pores (this is a barrier for penetration of the hair restorer) (steam process).

Next, the three-way valve 53 is rotated to communicate with the atmosphere, and the three-way valve 55 is closed and the three-way valve 57 is opened. Next, the peripheral seal portion 1 is passed through the pipe 47 by the vacuum pump 36.
7 is supplied with air. Then, the peripheral edge seal portion 17 is bulged inward and is brought into close contact with the side surface of the head H. When the pressure in the cavity 19 in the peripheral seal portion 17 reaches a predetermined pressure, the sensor is activated and the vacuum pump 36 is temporarily stopped. In this way, a closed space 33 is formed between the head H and the inner surface of the hair growth cap 11 as shown in FIG.

Next, the valve 57 is closed and the peripheral seal portion 1 is closed.
7 is brought into close contact with the head, the valve 53 is opened to communicate with the pipe 48, and the valve 55 is switched to communicate with the atmosphere. Then, the pipe 4 is moved by the vacuum pump 36.
Air is sucked from the closed space 33 in the hair growth cap 11 through 8 and exhausted from the valve 55 through the pipes 52 and 51. Thereby, the inside of the cap body 13 is brought into a vacuum state. Next, the valve 53 is closed.
5 is opened to communicate with the pipe 48, and pressurized air is injected into the closed space 33 through the pipe 54 and the pipe 48.

Thereafter, the scalp washing cycle including the steam injection and the pressurized air injection is repeated a predetermined number of times, for example, 17 times at intervals of about 5 seconds. Then, the excreted skin and fat around the hair root are discharged, and the surfactant remaining on the scalp is removed from the closed space 3.
3 to the outside. The cleaning cycle can be set to 1 to 99 times.

Thereafter, a hair growth cycle starts. In this hair growth cycle, the interior of the cap body 13 is evacuated with the peripheral seal portion 17 in close contact with the head, and the valve 64 is momentarily opened in this state. Then, the hair restorer supplied from the hair restorer supply unit 38 becomes fine particles by the pressurized air and is injected into the closed space 33. At this time, the valve 55 is open, and the vacuum pump 36 is driven to inject the pressurized air into the closed space 33, so that the hair restorer is pushed into the deep part of the scalp around the hair root by a predetermined pressure and penetrates. . The vapor applied to the scalp spreads the scalp around the hair root and promotes penetration of the hair restorer into the scalp around the hair root.

Next, the valve 55 is switched to communicate with the atmosphere to open the closed space 33. In addition, the valve 57 is communicated with the atmosphere to remove air from the peripheral seal portion 17, and one cycle is completed. Such a hair growth cycle is performed a predetermined number of times, for example, 17 times.
Repeated times. The hair growth cycle can be set to 1 to 99 times. When the chemical solution step is completed, the hair growth cap 11 is removed from the head. The hair restorer comprises a drug and an emulsifier such as a cream.

The above operations are performed automatically under computer control, and the operation of each valve is automatically controlled by a signal provided by a pressure switch. Adjustment of the degree of pressurization of the supplied air is performed by adjusting the degree of opening of the valve.

The above will be confirmed with reference to the flowcharts shown in FIGS.

First, the cap body 13 is put on the head and the steam generator 37 is turned on (ON) (step 11 (S1)).

2)), supply steam into the cap body 13. Next, when the steam generator 37 is turned off (Step 1)
3 (S13)), the valve 61 is closed (step 14).
(S14)). Thus, the steam process as pre-processing is completed.

Next, the process proceeds to a vacuum pressurizing step. That is, first, the pump 36 is turned on (ON) (step 21 (S2
1)), and set to the pressure mode (step 22 (S2
2)). Then, in conjunction with this, the valve 57 is turned on.
(Open) (Step 23 (S23)), and air is supplied to the peripheral seal portion 17, so that the peripheral seal portion 17 is turned on (ON) (Step 24 (S24)). When the peripheral seal portion 17 comes into close contact with the head (Step 25 (S2
5)) A sensor (not shown) senses this and the valve 57
Becomes OFF (closed) (step 26 (S26)). Thereby, a closed space 33 is formed between the cap body 13 and the head H. Next, step 27 (S27)
And the pump 36 enters the pressure reducing mode. Then, in conjunction with this, the valve 53 is turned ON (open) (step 28 (S28)), so that the air in the cap body 13 is sucked and the pressure inside the cap body 13 is reduced (step 29 (S2)).
9)). Next, in a state where the valve 53 is turned off (closed) and the vacuum state is maintained (step 30 (S3
0)), the valve 55 is turned on (open), and the pressurized air in the pipes 52 and 51 is exhausted to the pipe 54 (Step 31 (S31)). When the valve 55 is opened, the pipe 54 is communicated with the pipe 48, so that the exhausted air, that is, pressurized air is injected from the pipe 54 into the cap body 13 through the pipe 48 (step 32).
(S32)). By the injection of the pressurized air, the waste and the film layer loosened in the above-described steam process are blown off (Step 32 (S32)) and sucked (Step 29 (S29)). Next, the valve 55 is communicated with the atmosphere to return the pressure in the cap body 13 to normal pressure (step 33).
(S33)) Also, the valve 57 is communicated with the atmosphere to release the air from the peripheral sealing portion 17 (step 34 (S3)).
4)). Then, the peripheral seal portion 17 is turned off (open) (step 35 (S35)). That is, the peripheral edge seal portion 17 is once retracted from the head H. The cleaning cycle described above (Step 22 (S22) to Step 35 (S
After 35)) is repeated an appropriate number of times, for example, 17 times (step 36 (S36)), the pump 36 is turned off (OFF) (step 37 (S37)).

Next, the process proceeds to a steam process. This steam process is for one minute. The steps of each part are the same as described in [0021].

Next, the process proceeds to the chemical solution process. That is, first, the pump 36 is turned on (ON) (step 41 (S4
1)), and set to the pressure mode (step 42 (S4
2)). Then, in conjunction with this, the valve 57 is turned on.
(Open) (Step 43 (S43)), and air is supplied to the peripheral seal portion 17, so that the peripheral seal portion 17 is turned on (ON) (Step 44 (S44)). When the peripheral seal portion 17 comes into close contact with the head (Step 45 (S4
5)) A sensor (not shown) senses this and the valve 57
Becomes OFF (closed) (step 46 (S46)). Thereby, the closed space 33 is formed. Then step 4
7 (S47) and the pump 36 enters the pressure reducing mode.
Then, in conjunction with this, the valve 53 is turned on (open) (step 48 (S48)), so that the air in the cap body 13 is sucked and the pressure inside the cap body 13 is reduced (step 49 (S49)). Next, the valve 53 is turned off (closed).
And maintain the vacuum state (step 5
0 (S50)), the chemical liquid pump 63 is turned on (ON) (step 51 (S51)). Then, in conjunction with this, the valve 64 is momentarily turned on (about 0.25 seconds).
It becomes (open), and a chemical solution comprising a hair restorer, an emulsifier, and the like is supplied into the closed space 33 (step 52 (S52)).

Next, the valve 55 is turned ON (open) (step 53 (S53)), and the pipe 54 is connected to the pipe 48. Then, the air exhausted into the pipes 52 and 51 becomes a pressurized state,
4, is injected into the cap body 13 through the pipe 48. That is, the chemical solution supplied in step 51 (S51) is injected by compressed air into the closed space 33 having the vapor supplied in the previous steam process (step 54 (S54)). In addition, the inside of the sealed space 33 at this time is evacuated by the steps following step 47 (S47). Therefore, the chemical liquid is pushed into the hair root and penetrates by the synergistic action of the steam and the pressurized air. For this reason, it is possible to penetrate the hair without disturbing the hair, and it is applicable regardless of the remaining amount of the hair (applicable also to a person who maintains the current state). Next, the valve 55 is communicated with the atmosphere to return the inside of the cap body 13 to normal pressure (Step 55 (S55)), and the valve 57 is communicated with the atmosphere to remove air from the peripheral seal portion 17 (Step 56 (S56)). . Then, the peripheral edge seal portion 17 is turned off (OFF) (open) (step 57 (S57)). That is, the peripheral edge seal portion 17 is once retracted from the head H. The hair growth cycle described above (step 42)
(S42) through Step 57 (S57)) are repeated as appropriate,
For example, after repeating 17 times (step 58 (S58)),
The pump 36 is turned off (OFF) (step 59 (S
59)).

According to the hair growth cap 11 according to the above-described embodiment, a large number of projections 27 are formed inside the cap body 13 so as to protrude inward. A predetermined space 33 can be secured between the head 13 and the head H. Therefore, steam, a hair restorer, and the like supplied into the cap body for washing, hair restoration, and the like can be obtained.
Regardless of the amount of hair remaining, it can be spread evenly throughout the scalp.

Also, since a large number of projections 27 are formed inside the flexible cap body 13, the projections are pressed against the scalp when the vacuum is evacuated and the scalp is stimulated, so that the massage effect can be improved. Can be.

Further, a cavity 19 through which air can be introduced is provided at the opening edge of the cap body 13. A peripheral sealing portion 17 that seals closely to the
Since the inner diameter of the peripheral seal portion 17 in the natural state where air is not supplied is set to be larger than the outer diameter of the side surface of the head H, the peripheral seal portion 17 can be retracted when the cap is attached, and accordingly, The cap can be easily mounted. In addition, by operating the air supply and exhaust, the relationship between the peripheral seal portion 17 and the head H can be selected from both the sealed state and the open state. Therefore, the space between the peripheral seal portion 17 and the head H is sealed only when the airtight state is required, and the other portions are left open. Therefore, the head is prevented from being tightened for a long time and the head is not hurt. I do. Therefore, optimal processing can be performed in each processing such as washing and hair growth.

Further, since the peripheral seal portion 17 is provided with the metal belt 25 fitted on the outer periphery of the peripheral seal portion, the peripheral seal portion 17 moves outward when air is supplied to the cavity 19. The swelling can be prevented, so that the inward sealing can be reliably performed.

On the outside of the cap body 13,
Since the cap cover 29 that covers the cap body 13 is provided, a beautiful appearance can be provided.

The air flow in the vacuum pressurizing step or the chemical liquid step is suction in the depressurizing mode of the pump 36 and press-in in the pressurizing mode of the pump 36, and these opposing motions alternately appear on the scalp. Will work. Therefore, the blood circulation of the scalp is also promoted by this, so that the Masurge effect becomes good and the hair growth is also positively affected.

As the pressurized air, the exhaust of the sucked air is used to make the inside of the cap body 13 a vacuum state. That is, since the pump 36 is used for both vacuum depressurization and pressurization without providing a separate pump for pressurization, the entire apparatus becomes compact.

Further, since pressurized air can be used, even if the hair restorer contains not only alcohol-based components but also non-volatile components, it can easily penetrate into the hair root.

Further, since the steam step is performed before both the vacuum pressurizing step and the chemical liquid step, the reliability of sealing the peripheral edge seal portion 17 to the head H is further improved. That is, the water droplets of the steam injected in the steam process form the peripheral seal portion 1.
7, and as a result, the degree of adhesion between the peripheral edge seal portion 17 and the head H increases.

Further, a closed space 33 is formed between the head H and the inside of the cap body 13 to make a vacuum state, and steam and high-pressure air are jetted into the space 33. It is possible to remove waste products while spreading the skin, and to allow the hair restorer to efficiently penetrate into the hair root.

The present invention is not limited to the above embodiment. For example, a plurality of cavities 19 of the peripheral seal portion 17 may be provided, and as shown in FIG. In this way, when air is sent into the cavity 19, two inwardly bulging portions are formed at the top and bottom as shown by the dashed line, so that the sealing on the side surface of the head H can be more reliably performed. It can be carried out. That is, when the cavities 19 are provided in two stages in this manner, the diameter of each of the cavities 19 is reduced, so that the cavities 19 can be evenly expanded, and the surface area in contact with the head H is increased. Is further improved. In addition, since the surface area in contact with the head H is large, pressure on the head is reduced,
It prevents your head from hurting.

Further, the size of the peripheral edge seal portion 17 can be appropriately changed. For example, as shown in FIG. 9, appropriate steps 17 a, 17
By providing b, it is possible to correspond to various heads H having different sizes, and even when the head H is small, it is possible to further ensure the sealing.

The number of the protrusions 27 may be an appropriate number. Also, the shape or length of the tip of the projection 27 can be appropriately changed.

The material of the cap body 13 is arbitrary as long as it has flexibility, and may be, for example, rubber, synthetic resin, or the like. The method of manufacturing the cap body 13 is also optional.

The pneumatic machine can be used in place of a vacuum pump as long as it can discharge air from the enclosed space and supply pressurized air to the enclosed space.

As shown in FIG. 10 and FIG. 11, the projection 27 presses the inner projection 27a provided around the port 15 when the head is pressed under vacuum, but otherwise the projection 27a is separated from the head. (Specifically, for example, about 20 mm), and the outer protrusions 27b and 27c disposed outside thereof have a length that abuts on the head even at times other than the time of vacuum pressurization (specifically,
(For example, about 35 mm). This prevents the cap main body 13 from being shaken by the vacuum suction during the vacuum pressurizing step and the chemical solution step, and also contributes to promoting blood circulation.

[0042]

As described above, according to the hair growth cap according to the present invention, a predetermined space can be secured between the cap body and the head, and therefore the hair growth cap is provided inside the cap body for cleaning, hair growth, and the like. The supplied steam, hair restorer and the like can be evenly distributed throughout the scalp. In addition, when a vacuum is applied, the projections press the scalp to stimulate the scalp, thereby increasing the massage effect. Further, the cap can be easily mounted because the peripheral seal portion can freely move forward and backward. Furthermore, by operating the air supply and exhaust, it is possible to select either the sealed state or the open state for the relationship between the peripheral seal portion and the head, so that each processing such as washing, hair growth and the like can be performed. , The optimal processing can be performed.
