Massage device for breasts

## Abstract

A breast massage device includes a main body; a drive unit installed within the main body; and a massage disk mounted on the main body and coupled with the drive unit so as to be driven rotatably thereby. The massage disk has a central axis, a concave surface for covering a breast, and a periphery confining the concave surface, wherein the periphery has a highest point and a lowest point located at two opposite sides of the central axis such that a portion of the concave surface extending from the highest point toward the central axis is longer in curved distance than another portion of the concave surface extending from the lowest point to the central axis. A plurality of massage elements are mounted rotatably on the concave surface such that the massage elements are rotatable relative to the concave surface when the drive unit is activated.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a massage device, and more particularly to a massage device for breasts, specially the device is capable of providing hot massage effects to the breasts of a user.
2. The Prior Arts
Breasts are special and distinguishing characteristic of women. It is often considered as the standard beauty for all women. In the westerner points of view, the bustier the breast is, the more attraction of woman is increased. As the view of world changes, majority of the countries in the world, including our country, gradually accept the westernized view in the concept of aesthetic.
According to the current medical views, several suggestions are raised that partially massaging the breasts can increase the blood circulation and irritate inner metabolism so as to stimulate the reaction of breasts, which, in turn, results in the growth of breasts. It is also said that the massage of breasts can get rid of chest tightness.
A conventional breast massage device generally includes a motor or low voltage generating unit for stimulating part or at single spot of the breast. The massage is done only at the exterior portion of the skin such that the massage effect cannot penetrate into the deeper layer of the skin, which in turn, cannot stimulate the blood circulation. Under this condition, the majority of women does not rely on or trust the conventional breast massage device.
SUMMARY OF THE INVENTION
The objective of the present invention is to provide a massage device, especially for woman's breasts, which can get rid of the aforesaid disadvantages resulted from the use of the conventional breast massage device.
One specific feature resides in that through conventional mechanical driving structure and circuit paths, the massage device of the present invention can provide massage effects deep into the interior of the breasts in such a manner that the user being massaged can feel more than two types of massage actions so as to stimulate the blood circulation of the breasts, which, in turn, enhances the growth of breast and simultaneously softens those hard particles in the breasts, thereby improving the health thereof.
The breast massage device of the present invention accordingly includes a main body; a drive unit installed within the main body; and a massage disk mounted on the main body and coupled with the drive unit so as to be driven rotatably thereby, the massage disk having a central axis, a concave surface for covering a user's breast and a periphery confining the concave surface, wherein the periphery has a highest point and a lowest point located at two opposite sides of the central axis such that a portion of the concave surface extending from the highest point toward the central axis is longer in curved distance than another portion of the concave surface extending from the lowest point to the central axis, and a plurality of massage elements mounted rotatably on the concave surface such that the massage elements are rotatable relative to the concave surface upon activation of the drive unit. Owing to the asymmetric inclination of two portions of the concave surface, the massage disk provides waveform massage effects when the same is driven rotatably by the drive unit, which is different from a conventional massage device that provides two dimensional massage effects only.
The breast massage device of the present invention further includes a plurality of heat generating elements and circuits disposed below the massage disk. Preferably, thermistor, filaments, bulbs can serve as the heat generating elements which become hot upon passage of current through the circuits so as to generate thermal heat at the tips of the massage elements so as to warm up the user's breasts and at the same time providing massage actions to the user's breasts.
In order to enhance the massage effects of the massage elements, the materials for construction of the massage elements are selected from a group consisting of titanium, germanium, magnetic stone, Nano, infrared-emitting substance and ceramics.
In one embodiment of the present invention, each of the massage elements is shaped like a ball (glass ball). In another embodiment, a plurality of protrusion elements serving as the massage elements are disposed stationarily on the concave surface such that each of the protrusion elements is curved and protruded outward from the concave surface of the massage disk and has a narrow first end and a large second end, which increases gradually in height, width and surface area from the narrow first end toward the large second end. More preferably, two of the protrusion elements are disposed stationarily and annularly on the concave surface in an asymmetric manner with respect to a central axis or an eccentric axis of the massage disk so as to provide the optimal massage actions (such as rubbing and kneading) upon rotation of the massage disk.
