[0009]
On the other hand, a steam generator 21 is incorporated in the brush base 3. As shown in FIGS. 1 and 4, the steam generation device 21 supplies a water supply tank 22, a heater 23, and water in the water supply tank 22 to the heater 23, which are detachably attached to the tip of the brush base 3. It consists of a water absorbent 24. The heater 23 is formed by enclosing a heater element 26 in a heater case 25 made of a material having excellent thermal conductivity such as aluminum die cast, copper, or brass. The heater element 26 is formed by winding a heater wire 26 b around a heater bobbin 26 a, filling an insulator 27 around the heater wire 26 b, and end sealing with a silicon adhesive 28. As the heater element 26, for example, a positive temperature coefficient thermistor can also be used.
[0010]
The heater 23 is arranged inside a cylindrical heater holder 30 that is attached to the inside of the brush base 3 with screws 29, and the bottom is waterproof and sealed with a silicon adhesive or the like. As shown in FIG. 3, the lead wire 31 led backward from the heater element 26 of the heater 23 is connected to the power cord 32 attached to the rear end of the handle 2 via the circuit board 33 and the switch 34.
[0011]
In FIG. 1, a water supply cylinder port 22 a of the water supply tank 22 is inserted into the opening at the front end of the heater holder 30, and a water absorbent holder 36, which is removably inserted into the water supply cylinder port 22 a through an O-ring 35, attaches the packing body 37. Inserted through. A water absorbing body 24 made of heat-resistant nylon or the like is inserted and held in the water absorbing body holder 36, and an exposed portion of the water absorbing body 24 from the water absorbing body holder 36 is covered directly on the front end portion of the heater case 25 or on the heater case 25. It is made to contact via another water absorption body 38. Therefore, the surface of the heater case 25 is heated by the heat generated by the heater element 26 and transmitted to the water absorbent bodies 24 and 38, and the water or chemicals such as treatment lotions contained in the water absorbent bodies 24 and 38 are heated to steam. Is generated. In FIG. 5, 54 is a ball body provided inside the water supply tank 22, and when the water brush 22 is stored and stored in an upright posture with water or treatment lotion or the like placed in the water tank 22, Water or treatment lotion continues to be supplied to the 24 side so as to block the water supply port so as not to drop. A valve body 55 is provided in the water supply tank 22 for pressure adjustment.
[0012]
The steam emanating from the water absorbing bodies 24 and 38 is discharged from the inside of the heater holder 30 toward the steam discharge hole 6 of the brush base 5. For this purpose, as shown in FIGS. 1 and 6, an opening 39 is formed at a location facing the central region of the brush base 5 of the brush base 3, and an opening 40 is formed at a portion facing the opening 39 on the peripheral surface of the heater holder 30. A steam guide body 41 is provided in the openings 39 and 40 to guide and discharge the steam to the steam discharge hole 6 of the brush base 5.
[0013]
The steam guide body 41 is made of a material such as PBT resin (polybutylene terephthalate) having excellent heat resistance, chemical resistance and rigidity, and is formed in a cross-sectional dish shape corresponding to the square shape of the opening 39 of the brush base portion 3. A steam discharge port 42 fitted into the steam discharge hole 6 of the brush base 5 is projected upward from the wall 41a, and a flange 43 is formed to project outward from the lower end of the peripheral surface thereof.
The steam guide body 41 has a flange base 43 fitted between the inner surface of the peripheral edge of the opening 39 of the brush base part 3 and the upper surface of the peripheral edge of the opening 40 of the heater holder 30 via a silicon packing 44. 3 is fixed to protrude upward from the outer surface.
[0014]
As shown in FIGS. 1 and 4, the steam guide body 41 also serves as a member that supports the center of the brush base 5. That is, the steam guide body 41 has the steam discharge port 42 fitted into the steam discharge hole 6 of the brush base 5 as described above, and the central portion of the brush base 5 between the steam discharge ports 42 and 42 of the upper wall 41a. By receiving and supporting the inner surface, the brush base 5 is prevented from being excessively dented or displaced.
[0015]
A dent may also occur in the intermediate portion between the central portion and the peripheral portion supported by the steam guide body 41 of the brush base 5. Therefore, as shown in FIGS. 4 and 7, a large number of protrusions 20 are integrally projected toward the outer surface of the brush base portion 3 between the central portion and the peripheral portion of the inner surface of the brush base 5. 20, even when the brush base 5 is dented by a pressing force during brushing, the tip of the projection 20 abuts against the outer surface of the brush pedestal 3 and buckles, and the release of the pressing force causes the brush base 5 to return to its original space. It is ensured to return to the swollen state forming S.
[0016]
If the central portion having the steam discharge hole 6 of the brush base 5 is simply placed on and supported by the steam guide body 41, the bristles 4 in the central portion of the brush base 5 are inclined by the hair during brushing, and this inclination is accompanied by this inclination. The central portion of the brush base 5 is lifted from the steam guide body 41, or the steam discharge hole 6 is turned up by the peripheral wall of the steam discharge port 42, and the expansion deformation is applied. As a result, the hair cannot be sufficiently unwound, the peripheral edge of the steam discharge hole 6 of the brush base 5 is broken, or the steam from the steam discharge hole 42 is formed between the peripheral wall of the steam discharge hole 42 and the inner periphery of the steam discharge hole 6. Or enter the space S through a gap between the two.
[0017]
Therefore, as shown in FIG. 1, a locking projection 47 having a large-diameter portion 46 is integrally suspended from the center between the steam discharge holes 6 and 6 on the inner surface of the brush base 5, and the locking projection 47 is connected to the steam guide. A hole 48 provided at the center between the steam discharge ports 42 and 42 of the body 41 is press-fitted through a large-diameter portion 46 in a retaining manner. In this case, if a small-diameter shaft portion 49 (shown by a two-dot chain line in FIG. 1) is provided in advance below the large-diameter portion 46 of the locking projection 47, the locking projection 47 is connected to the steam guide body as described above. 41, first, the lower end of the small-diameter shaft portion 49 is passed through the hole 48 from above and protrudes downward from the inner surface of the steam guide body 41. After that, the lower end of the discharge port of the small-diameter shaft portion 49 is projected. The large-diameter portion 46 is easily passed through the hole 48 while being compressed and deformed by pulling the locking projection 47 and pulling it firmly downward. After the press-fitting of the locking projection 47, the small diameter shaft portion 49 is cut and removed from the lower end of the large diameter portion 46.
[0018]
In this way, when the central portion of the brush base 5 is coupled to the steam guide body 41 via the locking projection 47, the brush base 5 of the central portion of the brush base 5 is tilted by hair when brushing. It is possible to reliably prevent the central portion from floating from the steam guide body 41. Further, since the locking projection 47 provided integrally with the brush base 5 is freely elastically deformed, the cushioning property of the brush base 5 is not impaired.
[0019]
In actual assembly, the brush base 5 is first mounted on the brush pressing member 12, and the steam guide body 41 is fitted into the opening 39 so that the flange 43 abuts the inner surface of the periphery of the opening 39 of the brush base 3. Next, the brush base 5 is covered with the brush pressing member 12 on the outer surface of the brush base 3, and the locking projection 47 is press-fitted into the hole 48 of the steam guide body 41. Thereby, the state in which the brush base 5 is temporarily fixed together with the brush pressing member 12 on the outer surface of the brush base 3 is obtained. For this reason, it becomes easy to perform final fastening fixation of the brush pressing member 12 with respect to the brush stand part 3 after that.
In the above embodiment, only one locking protrusion 47 is provided on the brush base 5, but a plurality of the locking protrusions 47 are provided as illustrated in FIGS. 8A, 8B, and 8C. The steam guide body 41 can be combined.
The present invention may be a steam brush of a type provided with a blower that selectively supplies hot air or cold air from the brush base 5 portion to the inside of the main body case 1.
[0020]
【The invention's effect】
As described above, according to the present invention, the brush base 5 is made of an elastic material, and this is stretched over the outer surface of the brush base 3 with the space S therebetween. When it is tilted by the external force received from the hair, the brush base 5 is also elastically deformed and has excellent cushioning properties, so that it can be brushed smoothly while taking care of the hair.
Further, since the steam passes through the steam guide body 41 separate from the brush base 3 and the brush base 5, it is possible to prevent thermal deterioration, water absorption, and moisture absorption deterioration due to the steam of the brush base 3 and the brush base 5. Durability can be improved. Furthermore, since the steam guide body 41 is also used to support the substantially central inner surface of the brush base 5, it is possible to well prevent excessive dents and displacement of the elastic brush base 5 with a simple support structure.
Further, a latching protrusion 47 is integrally suspended at a substantially central portion of the brush base 5, and the latching protrusion 47 is inserted and coupled to the hole 48 of the steam guide body 41 so as to prevent the brush base 5. Without impairing the cushioning property, the lift from the steam guide body 41 can be prevented, and the hair-removing action can be suitably performed even at the location.
