Description

  The present invention activates the flow of body fluids such as blood and lymph by applying vibration and electrical stimulation to soft skin and muscles such as cheeks when massaging soft skin and muscles such as cheeks. More particularly, the present invention relates to a pin head for a massage device having a plurality of pins that move forward and backward in accordance with soft skin undulations such as cheeks.

  2. Description of the Related Art Conventionally, massagers that only give vibrations to skin have been widely used as massagers that attempt to recover fatigue of skin and muscles. In addition, a device is known that applies a low-frequency pulse electrical signal to muscles and muscles to activate the skin and muscles to increase natural healing power.

  However, in the case of a conventional massage device, vibration does not easily reach the inside of the muscle, and a sufficient effect is not necessarily obtained. In addition, in the case of a device that applies an electric signal of a low-frequency pulse, there is a “feeling of tingling” feeling at the portion where the electric signal is applied, which is not always comfortable.

  In view of this, the present applicant has proposed a massage device in Patent Document 1 that applies vibrations to skin and muscles such as cheeks and simultaneously applies an electric signal of a low frequency pulse through a plurality of pins. This massage device has vibration and low-frequency pulse electrical signals that reach the inside of the skin and muscles and does not have a “feeling tingling” feeling.

  After that, as a result of the massaging device proposed in Patent Document 1 having accumulated use results in cosmetics such as a beautiful face, since this massaging device has a plurality of pins fixed on the pin head, each of the plurality of pins is a cheek or the like. It does not follow the curved surface of the skin, does not contact the skin and muscles uniformly, and the contact strength between the pins is strong, and the vibration and low-frequency pulse electricity are not necessarily applied to the skin and muscles from each of the pins. Could not give signal.

  Therefore, in the patent document 2, the applicant of the present application disclosed that a plurality of pins almost uniformly contact the skin and muscles such as the cheeks to generate vibration and low-frequency pulse electrical signals that are as uniform as possible on the skin and muscles such as the cheeks. We proposed a massage device that can apply stimuli based on it (hereinafter referred to as “electrical stimulation”).

  However, in the case of the massage device proposed in Patent Document 2, a plurality of pins are fixed and supported on a flat plate, and the flat plate is inclined in all directions around a support pin fixed at the center. Because it is flexible, the plate tilts according to the undulations of the skin and muscles, but since the pins are fixed to the plate and do not follow the undulations of the skin and muscles, the pins have different pin pressures. In contact with skin and muscles, it was not always possible to give pleasant vibration and electrical stimulation.

Next, the operation of the massage device will be described. First, a battery is attached to the massage device main body M and the controller 12, and the respective power supplies are secured so that the massage device can be used. Next, if radio waves are transmitted to the massage device main body M by operating the controller, vibration and electrical stimulation can be applied from the 12 pins 11 of the pin head 10.

  For this purpose, the massage device body M has the operation unit 20 and when the operation button 25 is pressed, the massage device body M is switched on to generate vibration from the vibration generator 23 and to generate a low frequency pulse from the electric signal generator. An electrical signal is generated. In this state, the pin 11 of the pin head 10 is applied to a predetermined part of the cheek.

 For example, when the twelve pins 11 hit a predetermined part of the cheek, for example, the twelve pins 11 retreat into the pin head main body 12 along the curved surface of the predetermined part of the cheek against the elasticity of the coil springs 18. , Evenly and evenly contact the curved surface of the predetermined part. The twelve pins apply vibration generated by the vibration generator 23 to a predetermined portion of the cheek and apply an electrical signal of a low frequency pulse generated by the electric signal generator to apply electrical stimulation to the predetermined portion. A cosmetic massage is applied to a predetermined part of the cheek by these vibrations and electrical stimulation, and the flow of body fluids such as blood and lymph at that part can be activated to recover muscle fatigue and the like.

  When massaging the massage device body M in accordance with the curved surface of the cheek, the 12 pins 11 are all independent of the curved surface of the cheeks. It can move forward and backward elastically and smoothly through the coil spring 18 to uniformly apply vibration and electrical stimulation to a predetermined part of the cheek, and recover fatigue and the like by a comfortable massage. If the beauty-important cheeks are massaged using the pin head 10 of the present embodiment, the twelve pins 11 come into contact with each other with a uniform pin pressure in accordance with soft skin undulations such as cheeks and are smooth. The body fluid such as blood and lymph in this region can be activated to recover fatigue and the like.

  In the case of the pin head 10 of the present embodiment, the C ring 13A of the 12 pins 11 comes into contact with the first support column 2E via the cushion ring 15, thereby preventing the collision sound between the C ring 13A and the first support column 12E. Or, since it can be suppressed, there is no unpleasant sound and a comfortable massage can be performed without a sense of incongruity. Since the first and second cushion sheets 17A and 17B are also bonded to the back surface of the second conductive plate 14, the impact between the second conductive sheet 14 and the second column 12E or the annular column 12F. Can also be relaxed.

  There are various advantages when assembling the pin head 10. For example, after the pin 11 is assembled to the first support column 12E, when the second conductive plate 14 is fixed to the second support column 12H, the coil spring 18 is surrounded by the annular support column 12F and the proximal end portion of the pin 11 The second conductive plate 14 can be smoothly positioned and attached to the second column 12H via the positioning portion 12G and the notch portion 14C.

  In addition, this invention is not restrict | limited to the said embodiment at all, Each component can be design-changed suitably. For example, although the coil spring 18 is used as the conductive elastic member in the present embodiment, the present invention is not limited thereto, and for example, conductive rubber or the like can be used.
