Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to a body brush that is rotationally driven by an electric motor.

The present invention is particularly suitable for use in body brushes used in bathrooms.

〔overview〕

The present invention is a body brush equipped with a rotating brush driven by an electric motor in one housing, in which a plurality of brushes are arranged in parallel on the same plane, and the plurality of rotation plans are independently set slightly in the direction of the rotation axis. It is designed so that it can be displaced and its rotating shaft can perform a grinding motion around the axis, allowing it to be brushed according to the curved surface of the body.

[Conventional technology]

Conventionally, this type of device has been included in facial beauty devices, such as the one described in Japanese Patent Publication No. 60-865.

In addition, body brushes are known that can be used in the bathroom, and have a dry cell battery inside a waterproof housing, and a motor powered by the dry cell battery, in which multiple types of replaceable rotating brushes are inserted. There is.

[Problem to be solved by the invention]

However, in the above-mentioned facial beauty device, the mechanism is complicated because the driving means that originally performs the suction operation on the face is switched to drive the rotating brush.

This facial beauty device and the body brush described above both have one rotating brush, and there is almost no play in the axial direction and around the rotating shaft. For this reason, although it is possible to brush on a flat surface, it does not conform well to the curved surface of the body.

The present invention solves these problems and aims to provide a body brush that can sufficiently brush curved parts of the body.

[Means to solve the problem]

The present invention provides a body brush equipped with a rotating brush and an electric motor that drives the rotating brush, in which the rotating brush has a plurality of brushes arranged in parallel on the same plane of one housing, and each of the plurality of rotating brushes is The rotary shaft and the rotary drive shaft coupled to the electric motor are each independently configured such that the rotary brush is slightly displaced in the direction of the rotary shaft, and the rotary shaft is provided with a spring means that allows the rotary shaft to perform a sliding motion around the shaft. It is characterized by being connected.

The rotating brush may have a replaceable tip.

[Effect]

A plurality of rotating brushes driven by one electric motor are arranged in parallel on the same plane in one housing, and each rotating shaft of the plurality of rotating brushes rotates with respect to a rotational drive shaft connected to the electric motor. Since the rotating shaft is connected via a spring means that allows slight displacement in the axial direction and allows grinding motion around the axis, the surfaces of the multiple rotating brushes can be displaced independently, so it can be used even on curved surfaces of the body. Can be brushed.

The tip of the rotating brush is replaceable, so use the appropriate rotating brush depending on the body part, such as using a brush with a soft brush body for the face and a brush with semi-hard brush bodies for the chest or abdomen. Can be used. Also, by using a sponge instead of the brush body, a pine surge effect can be obtained.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an external view of one embodiment of the present invention, and FIG. 2 is a
FIG. 3 is an exploded view of a connection structure showing a connection between a rotation shaft of a rotating brush and a rotation drive shaft coupled to an electric motor.

In FIG. 1, rotating brushes IA, IB and an electric motor 2 shown by broken lines for driving the rotating brushes LA, IB are mounted in a housing 3 that can be held with one hand by a gripping portion 3A. The housing 3 includes a hook hole 3B that is locked by a locking means (not shown) and a curl cord 4 that supplies a driving current to the electric motor 2.

Here, the feature of the present invention is that two rotating brushes IA and IB are arranged in parallel on the same plane part 3C of the housing 3, and each rotating brush has a rotating shaft 5A.

5B is connected to the rotary drive shaft 6 which is connected to the electric motor 2 via a bevel gear 6A and a bevel pinion 6B via a common pinion 7$ and gears 8A and 8B.

The female cutout portions 5C formed on the rotating shafts 5A and 5B and the male protrusion portions 8C formed on the gears 8A and 8B are configured to mesh with each other with a gap in the circumferential direction. Further, a center rod 8D is provided in the axial direction of the gears 8A, 8B so that there is a gap between the outer periphery thereof and the inner surface of the female cutout 5C, and the center rod 8D is inserted around the center rod 8D. The reason is that a coil spring 9 is provided. The length of this center rod 8D is the same as that of the female cutout 5C and the male protrusion 8.
When C engages with the coil spring 9 and the tension of the coil spring 9 is applied,
The gap between the head of the center rod 8D and the inner end surface 5D of the female cutout 5C of the rotating shaft 5B is approximately 5 mm.

That is, since there is a gap of about 5 mm, when the housing 3 is pressed against the body while the rotating brushes LA and IB are brushing the skin, the coil spring 9 is compressed. Furthermore, since there is a gap in the circumferential direction between the male protrusion 8C and the female cutout 5C, and there is also a gap between the outer periphery of the center rod 8D and the inner surface of the female cutout 5C, the rotating shaft 5A
, 5B is relative to the rotation center of the center rod 8D,
It is possible to perform a grinding motion with an inclination angle of up to 10 degrees. The amount of compression of the two coil springs 9 and the angle of the grinding motion of the rotating shafts 5A and 5B are performed independently of each other.

In addition, when a person grasps the housing 3 with one hand and brushes various parts of the body, even if the same plane part 3C of the housing 3 is not parallel to the opposing skin surface, each rotation The brush can be applied almost evenly to the skin surface.

Further, a hollow protrusion 5E with a dowel 5F is formed on the opposite side of the female cutout 5C of the rotating shafts 5A, 5B, and a hollow protrusion 5E is formed with a dowel 5F.
It is inserted into the hollow part 1C provided with the dowel receiver ID of B (the same IA is omitted in FIG. 3).

Since the rotating brushes IA, IB and the rotating shafts 5A, 5B are respectively made of flexible plastic moldings, by twisting the rotating brushes IA, 1B, the rotating shafts 5A, 5B can be adjusted.
It is easy to attach and detach.

The rotating shaft 5A is formed by the dowel 5F and the dowel receiver ID.

The rotational force of 5B is transmitted to rotating blades IA and IB.

FIG. 3 is a sectional view of the main part of the connection structure.

The rotating brush has a brush-like tip portion with a nylon brush body implanted therein as shown in FIG. 4(a), a tip portion with a sponge body attached as shown in FIG. 4(b), and a tip portion as shown in FIG. 4(C). There is a tip with a pumice stone attached as shown in the figure below, and both are replaceable.

The brush-like tip can be soft or soft depending on the type of brush body.
There are semi-hard and hard types; the soft type is used for the face and neck, the semi-hard type is used for the chest, abdomen and back, and the hard type is used for the elbows. The tip with the pumice attached is used for the heel. The tip with the sponge attached is used for rubbing with a dry cloth or applying sun oil, etc.

In this way, this embodiment can be used not only for bathing, but also for rubbing with dry cloth.

FIG. 5 is an overall layout diagram showing a panel 11 that is hung when the housing 3 of this embodiment is not in use, and a waterproof battery case 21 that houses a secondary battery that supplies drive current to the electric motor 2. shows. The panel 11 is connected to the housing 3 via a waterproof curl cord 4 and to the battery case 21 via a cord 12. The panel 11 is suspended from a wall hook 13A attached to a wall surface 13 in the bathroom. The housing 3 is connected to the panel 11 by the hook hole 3B (not shown in FIG. 5).
It is hung from a hook 14 and held by a support 15 so as not to sway. Reference numeral 16 denotes an opening/closing door to which a mirror 16A is attached, and a shelf 17 inside thereof stores the tip of the rotary brush that is not used.

The center of the operation panel is provided with a main switch SL, a reverse switch S2, a push button BI for increasing the rotational speed of the motor, a pushbutton B2 for reducing the rotational speed as well as a pushbutton BI for increasing the rotational speed of the motor, and display sections LE, -LE using light emitting elements. Display section L E +
is an operation display, display parts LE2 and LE3 are a display of the rotation direction of the rotating brush, and display part LE4 is a display part in which the number of light emitting elements increases or decreases depending on the magnitude of the rotation speed. be.

In this way, only the curl cord 4 is connected to the casing 3, and there is no control means such as push buttons, so that a sufficiently waterproof structure can be achieved with an appropriate configuration. Further, since the capacity of the secondary battery in the battery case 21 is 12V15AH, a motor with sufficient power can be selected.

Although the panel 11 has a waterproof structure, it weighs approximately 2 kg while holding the casing 3, so it can be easily moved.

Therefore, the wall surface 13 is roughly installed on a suitable wall surface other than the bathroom, and the entire device can be easily moved by using the handhold portion 18 shown by the broken line on the panel 11. During this movement, the battery case 21 is separated and moved by the waterproof connector 12A of the cord 12.

FIG. 6 shows a block diagram of the overall control circuit of this embodiment.

〔Effect of the invention〕

As explained above, according to the present invention, curved parts of the body that are difficult to touch with the casing of the rotary brush held in one hand can be brushed comfortably and for a long period of time.
