Description

  The present invention relates to a massage device that is miniaturized.

  A conventional massage device uses a power source that uses the rotational force of the motor or a combination of the attractive force of an electric magnet and the repulsive force of a spring as the power source of the massage device. .

  Hereinafter, the configuration of the power source of the conventional massage device will be described with reference to the schematic diagrams of FIGS. 3, 4, and 5. In FIG. 3, reference numeral 40 denotes a motor body, and an eccentric cam 42 is fixed to the motor shaft 41. In this configuration, the outer periphery of the eccentric cam moves eccentrically by the rotation of the motor shaft.

  In FIG. 4, reference numeral 43 denotes an arm, which supports a fulcrum 44 and has one end brought into contact with the outer periphery of the eccentric cam 45, and the other end of the arm is reciprocated by the rotation of the motor shaft 46. Thus, the massaging work is performed.

  In FIG. 5, 47 is an electric magnet, and a diaphragm 49 is installed with a spring 48 interposed therebetween. When the current is turned on, the diaphragm is attracted by the attractive force of the electromagnet, and when the current is turned off, the diaphragm is returned to the original position by the repulsive force of the spring. By repeating this ON and OFF, the diaphragm is vibrated to perform a massage operation.

  In the conventional massage apparatus described above, the motor / electric magnet, the spring and the diaphragm combined with the power source are large in shape and heavy in mass. It was difficult to wear it with a belt. .

  The present invention solves the problems of such a conventional configuration, realizes a smaller and lighter massaging device, and can be easily attached to a predetermined massaging site. The purpose is a massage device.

  In order to achieve the above object, the massage device according to the present invention is divided into a power source and an oscillator that shares the mass work, and the intermittent power generated by the air pump using the air pump is used as the power source. -It is characterized in that it is supplied to an oscillator by a generator and a massage effect is generated by air vibration of intermittent air by the oscillator.

  Further, in the oscillator, a vibrator made of a flexible material is held by a sleeve, and the sleeve is configured so that the vibrator is movable by fitting the sleeve to the guide and the base. Press contact with the upper surface. This embodiment is characterized in that the outer edge of the vibrator is a convex position from the bottom surface of the base.

  Further, the vibrator has a shape in which a central air outlet portion is recessed from the outer edge, and a space portion is formed between the air outlet portion and the mounting surface to block outside air. Further, a concave groove that connects the air outlet portion to the outer edge is provided. It is characterized by these shapes.

  The massage device of the present invention can reduce the size and weight of the oscillator of the massaging work unit by separating the air pump of the power source and the oscillator that generates the massaging work.

  Furthermore, since the outer edge of the oscillator of the oscillator is a convex position from the lower surface of the base, the outer edge can be brought into close contact with the mounting surface by moving the vibrator and pressing it with spring force even on a curved mounting surface. .

  Furthermore, since the vibrator is made of a flexible material, the outer edge has good adhesion to irregular mounting surfaces, and it is possible to block the external air in the space formed between the vibrator and the mounting surface. And the massage effect of intermittent air to be ejected can be efficiently generated.

  Furthermore, by providing a groove that connects the central air outlet to the outer edge, the air blown into the space is smoothly discharged into the outside air, preventing vibration at the outer edge and gentle air vibration to the mass part. Can be obtained.

  As described above, the massaging device of the present invention uses air vibration as a power source, so it is gentle on the massaging part, and on a curved surface or an irregular mounting surface by realizing a small size and light weight of the oscillator. It can be attached with a belt and massaged.

  The best mode of the present invention will be described below with reference to FIGS.

  FIG. 1 is a block diagram of a massaging device according to the present invention. Reference numeral 1 is a power source air pump, which is a small air pump that generates a small amount of intermittent air at a low pressure, such as a commercially available plunger pump or diaphragm pump. Is used. A commercially available air pump and a timer are integrated, and a magnetic shielding cover is provided to prevent electromagnetic leakage generated from the air pump.

  The oscillator 2 shown in FIG. 1 has a vibrator 20 at the center lower part and a base 21 made of a resin molded product on both sides thereof. The belt 22 fastened to both ends of the base places the oscillator at a predetermined position on the body. The intermittent air generated by the air pump by the hose 3 is supplied to the oscillator.

  FIG. 2 is a cross-sectional view of the oscillator. The vibrator 20 provided at the lower center portion has a rotor shape so as to form a space portion 24 that is blocked from outside air between the vibrator and the mounting surface 23, and has an outer edge 20a and an irregular mounting surface. The vibrator is made of a plastic flexible material in order to provide a good barrier property.

  Further, a concave groove 20c connected from the air hole outlet 20b at the center to the outer edge is provided, and intermittent air is ejected from the air hole outlet into the space to generate a massage effect. By discharging the air smoothly, the occurrence of micro vibrations due to intermittent air discharge between the outer edge and the mounting surface is reduced.

  The guide 25 in FIG. 2 is formed by turning from a brass bar or an aluminum bar, and is a stepped cylindrical body including an upper guide 25a and a lower guide 25b. The upper guide 25a is sized to fit the hose 3 into the inner diameter, the outer diameter is sized to press fit into the upper case 28a, and the lower guide 25b is sized to fit the upper sleeve 26a into the inner diameter. The spring 27 is inserted into the dimension. This guide is press-fitted and bonded to the inner diameter of the upper portion 28a of the case made of a resin molded product, so that the guide and the case are integrated.

  The sleeve 26 shown in FIG. 2 is formed by turning from an aluminum bar. The upper sleeve 26a, the lower sleeve 26b, and the lower sleeve at the center of the outer diameter of the lower sleeve 26 are arranged on the upper side. This is a stepped cylindrical body provided with a convex ring portion 26c serving as an insertion stopper and serving as the positioning of the fitting portion with the inner hole of the base 21 on the lower side. The upper sleeve 26a is an intermittent air passage hole dimension that connects the inner diameter from the guide inner diameter, the outer diameter is fitted to the lower guide inner diameter, and the lower sleeve 26b is a dimension that presses the boss outer diameter of the vibrator 20 into the inner diameter. The outer diameter is dimensioned to fit into the base 21 inner hole.

  A spring 27 is inserted into the outer diameter of the lower guide 25b, which is an integral part of the guide and the case, and the upper sleeve 26a is fitted into the inner diameter of the lower guide, whereby the spring is connected to the lower guide and the lower sleeve. -Inserted into the outer diameter of the upper side of the hub and sandwiched by the upper side of the convex ring portion 26c.

  Further, the base 21 is fitted to the outer diameter of the lower sleeve 26b and the inner diameter of the lower case 28b, and the case and the base are fixed with screws 29. Thus, the sleeve 26 is fitted to the inner diameter of the lower guide and the inner hole of the base to move up and down, and the lower side of the sleeve convex ring portion 26c is pressed against the upper surface 21a of the base by the spring force. Furthermore, when the boss outer diameter of the vibrator is press-fitted into the inner diameter of the lower sleeve, the outer edge 20a of the vibrator becomes a convex position from the base lower surface 21b. Then, the hose 3 connected to the air pump 1 is fitted into the inner diameter of the guide 25a.

  The above configuration will be described. If the oscillator 2 is attached to a predetermined massage site with the belt 22, the outer edge 20a of the vibrator 20 fixed to the sleeve is in a convex position from the base lower surface 21b. It moves to the same position as the base bottom surface. By this movement, the spring 27 inserted into the sleeve outer diameter and the guide outer diameter is compressed, so that the repulsive force of the downward spring is related to the sleeve, and the outer edge of the vibrator fixed to the sleeve is attached. Press contact with the surface. Thus, since the outer edge of the vibrator is flexible, even if it is an irregular mounting surface, the outer portion of the space 24 is well cut off. By supplying intermittent air generated by the air pump 1 to the oscillator of this form with the hose 3 and ejecting it from the air hole outlet 20b of the vibrator to a space portion that is cut off from the outside air, air vibration due to the intermittent air is generated. A massage effect is obtained on and around the mounting surface that is generated to form one side of the space.
