Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to an electric brush used to stimulate a predetermined part of the head or the like.

<Prior art> Conventional electric brushes of this type have a structure in which a drive source such as a motor rotates a brush that stimulates a predetermined part of the head, etc. However, when attempting to promote hair growth, the hair becomes entangled with the brush that stimulates a predetermined part of the head, resulting in a drawback that the hair cannot be sufficiently stimulated.

<Purpose of the invention> The object of the present invention is to provide an electric brush that eliminates the above-mentioned drawbacks.

<Embodiment of the invention> An embodiment of the electric brush of the invention will be described below with reference to the drawings.

The electric brush of the present invention has a main body case 1 that can be divided into a first case 2 and a second case 3, and a battery storage section 5 in which a battery 4 is stored in the first case 2.
At the same time, a motor 6 which rotates using the battery 4 housed in the battery storage section 5 as a power source is attached, and a pin 9 is fixed to the rotating shaft 7 of the motor 6 via a gearbox 8 having a built-in pinion worm. Connecting the shafts 10, the shafts 10
Fit the tip of the joint into the fitting hole 12 of the joint 11,
The joint 11 is always biased by a spring 13 in the direction of arrow A in FIG. 1, and is disposed in the second case 3 so as to be slidable in the axial direction of the joint 11 (direction of arrow B in FIG. 1). , a brush 14 is detachably attached to the tip of the joint 11.

In the above configuration, the main case 1 is formed by attaching the first case 2 and the second case 3 with screws 15, and the battery storage section 5 is formed by connecting the opening 16 of the battery storage section 5 to the second case 3. 2, the battery cover 17 is detachably attached to the case 3, and a pin 9 is press-fitted into the shaft 10 to fix it, and the joint 11 is the same as the one described above. pin 9 of shaft 10
The planar sliding portion 18 that slides the planar sliding portion 18
A sliding surface 20 is formed with a U-shaped sliding portion 19 provided to sandwich the joint 11, and the joint 11 is fitted onto the guide rib 21 of the second case 3 so that the joint 11 slides in the joint axial direction. A sliding groove 22 is provided for sliding together, and an engaging piece 23 using a resin spring is provided at the tip of the joint 11 to engage and attach the brush 13.
In FIG. 3, 24 is a sliding hole of the joint 11 provided in the second case 3.

In the electric brush of the present invention configured as described above, the battery cover 17 of the second case 3 of the main body case 1 is attached and detached to store the battery 4 in the battery storage section 5, and the battery 4 is used as a power source. The rotating shaft 7 of the motor 6 is rotated, and the rotation of the rotating shaft 7 of the motor 6 is transmitted to the shaft 10 via the gear box 8 to rotate the shaft 10, and the rotation of the shaft 10 causes the pin of the shaft 10 to rotate. 9 is slid on the sliding surface 20 of the joint 11, which is constantly biased by a spring 13 in the direction of arrow A in FIG.
The brush 14, which is removably attached to the joint 11, is reciprocated by the reciprocating movement of the joint 11, and the brush 14 is applied to a predetermined part such as the head, and the brush 14 is moved back and forth. At step 14, a predetermined part of the head or the like is stimulated to improve blood circulation in the predetermined part of the head or the like to improve health.

<Effects of the invention> Since the electric brush of the invention has the above-described configuration, the rotation of the motor is transmitted to the brush and the brush is reciprocated perpendicular to the mounting surface.
Compared to a method in which the rotation of the rotary shaft is made into a rotational movement around the rotational shaft using a separate member, and this rotational movement directly drives the brush back and forth in the vertical direction, it is easier to connect the rotational shaft of the motor with a brush, etc. The applied pressure can be reduced, battery consumption due to an increase in motor load current can be prevented, and damage to the rotating shaft of the motor can be prevented.
