The hand massage machine 1 is housed over the main body 2, the drive head 3 provided in a state of protruding to the tip of the main body 2 (upward in FIG. 1), and both the main body 2 and the drive head 3. The drive mechanism 4 and the treatment attachment 5 that can be attached to the drive head 3 in an outer fitting manner as needed.
The main body 2 has a thickness that can be gripped with one hand of the user and is formed of a resin or the like, and has an outer peripheral surface as a gripping portion.

The end surface shape (outer peripheral contour shape of the cross section) of the main body 2 is preferably a circle, but may be an ellipse, an oval, a square, or the like. Further, the outer peripheral surface of the main body 2 may be provided with unevenness or a grip rubber so as to prevent slipping.
The inside of the main body 2 is a cavity, and a mechanical storage 7 is provided on the tip side in the cavity, that is, on the side where the drive head 3 is provided. A battery housing portion 8 is provided inside the main body portion 2 on the other end side. The mechanical storage unit 7 and the battery storage unit 8 are in communication with each other. A part of the drive mechanism 4 is stored in the mechanical storage unit 7, and a battery 10 is stored in the battery storage unit 8. .

A distal end opening 12 is provided at the distal end of the main body portion 2 so as to penetrate between the mechanical storage portion 7 and the outside of the main body portion 2. The portion housed in the housing portion 7 and the portion housed in the drive head 3 are mechanically connected. In the illustrated example, the outer peripheral wall 13 surrounding the tip opening 12 protrudes from the main body 2, and the protruding end is inserted into the drive head 3 as a shape that is narrowed down like a nozzle so as to protrude. It shows what was formed.
The other end of the main body 2 is provided with a tail opening 14 that penetrates between the battery housing 8 and the outside of the main body 2, and the battery housing 8 is connected to the tail opening 14 via the tail opening 14. The battery 10 to be stored and the charger 15 prepared separately from the main body 2 can be electrically connected. In the example shown in the figure, a jack 16 is provided inside the tail opening 14 so that the plug on the charger 15 side can be inserted and removed.

Although not shown, the jack 16 and the battery 10 are electrically connected, and the battery 10 and the drive mechanism 4 are electrically connected. The discharge state of the battery 10, the charging state when the charger 15 is connected, and the charging completion (full charge) state are the lighting color of the charging lamp 17 provided at an appropriate position of the main body 2, the presence or absence of blinking, or What is necessary is just to be able to confirm by switching, such as the presence or absence of lighting.
A switch 20 for driving or stopping the drive mechanism 4 is provided on the outer surface of the main body 2 in a state where the operation knob is exposed to the outside.

The drive mechanism 4 is housed in the drive head 3, a rotation drive shaft 21 that connects the mechanical housing portion 7 of the main body 2 and the inside of the drive head 3, a drive motor 22 that drives the rotation drive shaft 21, and the drive head 3. The vibration generating unit 23 is provided.
The rotational drive shaft 21 is formed by a coiled coil spring, one end of which is connected to the motor shaft 25 of the drive motor 22 so as to be integrally rotatable, and the other end is directed from the vibration generating unit 23 toward the drive motor 22. The input shaft 26 is connected to the input shaft 26 so as to be integrally rotatable.
The vibration generating unit 23 incorporates an eccentric weight (not shown) that is eccentric with respect to the input shaft 26 and rotates integrally with the input shaft 26. When the input shaft 26 is driven to rotate, the eccentric weight is biased in the radial direction. Rotation blur is generated and this becomes a vibration source. By setting the weight, the amount of eccentricity, the number, and the arrangement of the eccentric weight as well as the rotational speed of the drive motor 22, it is possible to obtain a “fine vibration” with a small amplitude and a high frequency, or a large amplitude. It is possible to obtain a swaying “sway” with a relaxed frequency.

The drive motor 22 may be provided with a control circuit that allows the user to adjust the number of rotations so that the degree of vibration ranging from “fine vibration” to “swing” can be arbitrarily changed.
As described above, since the rotary drive shaft 21 is formed by a tension coil spring, the input shaft 26 and the motor shaft 25 are flexibly bent when the vibration generating portion 23 vibrates, and the drive transmission between the shafts 25 and 26 is not performed. Always maintained. Further, since the rotary drive shaft 21 has an axial contraction force as a tension coil spring, the drive head 3 is excessively bent even if a strong centrifugal force due to high-speed rotation or a lateral external force due to contact acts on the drive head 3. The main body 2 and the drive head 3 are returned and held in a uniaxial arrangement when not in use (when rotation is stopped).

The drive motor 22 can be driven by power supply from the battery 10, and is switched on and off by the operation of the switch 20.
The drive head 3 is formed in a rotationally symmetric shape with the axis of the rotational drive shaft 21 as the center. In this embodiment, it is a cylindrical cap with the tip closed in a hemispherical shape. As described above, since the vibration generating portion 23 of the drive mechanism 4 is provided inside the drive head 3, the hand massage machine 1 includes the main body portion 2, the drive head 3, The center of gravity is provided closer to the drive head 3 than the main body 2.

  The treatment attachment 5 can be attached to the drive head 3 in an outer fitting shape. This treatment attachment 5 is also formed in a rotationally symmetrical shape with the axis of the rotational drive shaft 21 as the center. The treatment attachment 5 shown in FIG. 1 to FIG. 3 (hereinafter referred to as the treatment attachment 5 of the first embodiment) is such that the drive head 3 is enlarged once (the tip is closed in a hemispherical shape). A cylindrical cap), and the outer peripheral surface thereof was coated with rubber or resin having appropriate softness. These forming materials and shapes are not particularly limited.

The treatment attachment 5 can be easily and repeatedly attached and detached from the drive head 3 through an appropriate detachable structure. In this embodiment, the screw coupling structure by the external thread part 31 formed in the outer peripheral surface of the drive head 3 and the internal thread part 30 formed in the internal peripheral surface of the treatment attachment 5 is employ | adopted as a detachable structure. . In addition, you may employ | adopt the detachable structure by uneven | corrugated engagement etc.
4 and 5 show a second embodiment of the treatment attachment 5.
In the treatment attachment 5 of the second embodiment, a cylindrical cap (rotationally symmetric about the axis of the rotation drive shaft 21) whose tip is closed in a hemispherical shape is used as a basic shape, and radially arranged from its outer peripheral surface. A large number of spine-like protrusions 35 having round tips are provided.

In the treatment attachment 5 of the second embodiment, an internal thread portion 30 is formed on the inner peripheral surface of the treatment attachment 5 so as to be detachable from the external thread portion 31 of the drive head 3 by a screw coupling structure. It has compatibility with the form treatment attachment 5.
6 and 7 show a third embodiment of the treatment attachment 5.
In the treatment attachment 5 of the third embodiment, a cylindrical cap (of the rotary drive shaft 21) whose outer end is closed in a flat state with a slight bulge and has an outer shape like a lotus flower. A basic shape is a rotationally symmetric shape centered on the shaft center, and a plurality of acupressure balls 36 are embedded in the distal end surface so as to partially protrude.

In the treatment attachment 5 of the present embodiment, an internal thread portion 30 is formed on the inner peripheral surface of the treatment attachment 5 so as to be detachable by a screw coupling structure with the external thread portion 31 of the drive head 3. It has compatibility with the treatment attachment 5.
Next, the operation when the drive mechanism 4 is driven in the hand massage machine 1 will be described.
First, the user selects the treatment attachment 5 (the first embodiment to the third embodiment, etc.) as desired, externally attaches this to the drive head 3, and then turns on the switch 20. The drive motor 22 is operated. As a result, the rotation drive shaft 21 is rotated, and the vibration generator 23 generates vibration set in the range of [fine vibration] to [sway]. Therefore, this vibration is transmitted to the treatment attachment 5 that is externally fitted around the drive head 3, and the treatment attachment 5 is perpendicular to the longitudinal direction of the main body 2 (radially outward). It starts to sway.

When the user presses the treatment attachment 5 against a portion such as the shoulder or back to be massaged, a massage operation similar to vibration or tapping can be obtained. Therefore, the user of the hand massage machine 1 can obtain a desired acupressure feeling in accordance with the outer surface shape of the treatment attachment 5.
Alternatively, the treatment attachment 5 may be pressed against a portion to be massaged, such as the shoulder or the back, with the driving head 3 exposed without attaching the treatment attachment 5 externally. In this case, since the drive head 3 is naturally thinner than the treatment attachment 5 and has a hard tactile sensation, it is possible to obtain a feeling of acupressure different from the case where the treatment attachment 5 is used. .

Since the hand massage machine 1 is provided with a center of gravity on the drive head 3 side, vibration (massage operation) of the vibration generating unit 23 is generated around the drive head 3, so that the main body 2 can be gripped. It becomes easy. In addition, the massage operation is efficiently transmitted to the user's treatment position.
Further, since the drive head 3 and the treatment attachment 5 are formed based on a rotationally symmetric shape, the gripping direction of the main body portion is determined when contacting the user's treatment position (a position such as the back or shoulder that cannot be seen by the user). Since it is not necessary to change each time, it is convenient in use. Furthermore, since the battery 10 is built in, the main body part 2 does not have a power cord that obstructs its use, and handling in use is extremely convenient.

In the course of continuing the massage, the treatment attachment 5 may be exchanged or removed at any time according to the user's desire.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, the shape and material (tactile sensation) of the drive head 3 and the treatment attachment 5 are not limited at all, and various things such as a target lens shape or a shape in which the central portion is recessed like a heel other than those illustrated. Can be adopted.
