Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a portable electric massager.

0002

[Conventional technology]

In conventional portable electric massagers, a rotary disk with multiple massage rollers is used. However, only its center portion was connected to and pivoted to the output shaft of the electric motor.

0003

[Problem that the idea aims to solve]

However, in conventional electric massagers, the rotary disk is supported (pivotally supported) only at the center. This had the disadvantage that the rotary disk would wobble during use.

0004 Furthermore, the shaft at the center of the rotating disk is made of plastic and is integrally molded with the rotating disk. If you The shaft sometimes broke when pressed, and its durability was low.

[0005] Therefore, the present invention was developed to prevent the rotary disk from rattling and to provide a highly durable mobile phone. The purpose is to provide a Qi massager.

[0006]

[Means to solve the problem]

In order to achieve the above object, the electric massager according to the present invention includes a plurality of massagers. It is equipped with a rotary disk having a surge roller, and the rotary disk has a metal shaft in the center. It has a body shape, the rest is molded from plastic, and the shaft is and the rotary disk is operatively connected to a drive device, and further, the rotary disk has the central portion having the shaft. , and is rotatably supported by a bearing at the outer peripheral edge.

[0007]

[Effect]

Place the massage roller in contact with a part of the body such as the foot or back, and turn on the power. Drive The driving force of the moving device is transmitted to the rotary disk through the shaft, supporting the center of the rotary disk. A bearing that supports the outer peripheral edge of the rotary disk and a bearing that supports the outer peripheral edge of the rotary disk support the rotation while supporting the rotary disk. The board rotates smoothly without rattling. In other words, the two bearings inside and outside the body It is sufficient to withstand the reaction force transmitted through the rollers.

[0008]

【Example】

Hereinafter, the present invention will be explained in detail based on drawings showing embodiments.

[0009] 1, 2 and 3 show a portable electric massager according to the present invention. The surge device is detachably attached to the massage device body 1 and the massage device body 1. A handle portion 2 (see FIG. 4) that is approximately Y-shaped in plan view.

0010 Therefore, the massage device main body 1 has a plurality of massage devices in the lower opening of the main body case 3. A rotary disk 6 having surge rollers 7 is provided.

[0011] The main body case 3 has a bean-shaped gripping head 22 at the upper end.

0012 As shown in the cross-sectional view of FIG. The lower end of the shaft 8 is integrally formed, and the rest is molded from plastic. The part 10 is knurled so that it can be firmly attached to the remaining part.

[0013] Furthermore, the upper end of the shaft 8 is interlocked and connected to a drive device 4, and the drive device 4 includes: It consists of a motor 5 and a reducer 20.

[0014] To explain in more detail, a spline (gear) is formed in the upper half of the shaft 8. is inserted into the gear hole of the final stage gear 21 of the reducer 20 and interlocked.

[0015] Further, the center portion 9 having the shaft 8 of the rotary disk 6 and the outer peripheral edge 11 of the rotary disk 6 are 6 is rotatable and supported by bearings 12 and 18.

[0016] That is, the bearing 12 in the center part 9 is a needle bearing or a ball bearing, and the outer peripheral edge 11 is a needle bearing or a ball bearing. It is a ring-shaped plain bearing made of fluororesin, copper alloy, oil-impregnated metal, etc. There is.

[0017] The bearing 18 at the outer peripheral edge 11 has a substantially square cross section, and the main body case 3 The stepped portion formed on the inner circumferential surface near the lower opening of the The bearing 18 is slidable in the gap formed between the stepped portion and the stepped portion. It has been incorporated.

[0018] Furthermore, as shown by the imaginary line in Fig. 3, the breathable cover 13 is attached to the main body case. It is also preferable to install it near the lower opening of the base 3.

[0019] Also, if you attach the handle part 2 as shown in Figure 1, you can easily reach hard-to-reach areas such as the back of the body. On the other hand, as shown in Figure 2, you can remove it and grasp the grip head 22 to massage the chest or Massage your arms, etc.

[0020] Further, in this embodiment, the massage rollers 7... are inclined with respect to the rotation axis of the rotary disk 6. However, as shown in FIG. It is also preferable that the rotational axes of the surge rollers 7 are perpendicular to each other.

[0021] Then, the massage roller 7 of the rotary disk 6 is brought into contact with a part of the body such as the foot or back. When the power is turned on, the rotary disk 6 rotates smoothly.

[0022] When used as described above, the rotary disk 6 receives a pressing force in the axial direction or in the direction perpendicular to the axis. The pressing force is distributed to the bearings 12 and 18 that rotatably support the rotary disk 6.

[0023] That is, the outer peripheral edge 11 of the rotary disk 6 has a ring shape and a substantially square cross section. The bearing 18 is located at the stepped portion near the lower opening end of the main body case 3 and at the outer peripheral edge of the rotary disk 6. 11, the bearing 18 rotates in the rotational axis direction (axial direction) of the rotary disk 6 (direction) and in a direction perpendicular to the axis (radial direction).

[0024] In addition, the center portion 9 of the rotary disk 6 receives a force in the radial direction by a bearing 12. Let's go.

[0025] Therefore, the rotary disk 6 is supported by the center portion 9 and the outer peripheral edge 11 as described above. Therefore, the rotary disk 6 can withstand large external forces and rotate smoothly without rattling. Ru.

[0026] Next, FIG. 5 shows another embodiment, in which a brush having brush bristles 16... The cover 15 is placed over the rotary disk 6 from below and is detachable.

[0027] That is, the brush 15 is provided on the lower end surface of the shaft 8 of the rotary disk 6. It is installed with the mounting screw 14 in the screw hole that matches the axis of the plate 6, and the rotary plate 6 rotates. This causes the brush 15 to rotate.

[0028] In addition, convex teeth are formed on the outer peripheral edge of the brush 15, and the brush 15 has convex teeth formed on the outer peripheral edge thereof. The outer peripheral edge is formed with a recess into which the convex teeth engage, thereby transmitting rotational torque.

[0029] Note that the present invention is not limited to the illustrated embodiments, and may be applied without departing from the gist of the present invention. Design changes are free.

[0030] For example, instead of making the gripping head 22 at the upper end of the main body case 3 into a bean shape as shown in FIG. It is also preferable to have a connection part for the electrical cord at the apex of the conical shape, such as a hemispherical shape. .

[0031]

[Effect of the idea]

Since the present invention is configured as described above, it produces the following effects.

[0032] The rotary disk 6 is rotatably supported by bearings 12 and 18 between the center portion 9 and the outer peripheral edge 11. Because the massage roller 7 is Even if used in a It can be rotated easily.

[0033] Therefore, a large load is not applied to the center portion 9, and the shaft 8 is made of metal. Since it is made of aluminum, the center portion 9 is less likely to break and its durability can be improved.
