Description

[Detailed description of the invention] Technical field The present invention is an improvement of a massaging machine, more specifically, a massaging machine that is installed to obtain a pine surge effect by continuously vibrating a vibrator back and forth and hitting the affected area. Regarding.

Conventional technology It is well known that applying stimulation to the human body, such as by massaging, hitting, or vibrating, can promote blood circulation, thereby increasing metabolism and producing a pine surge effect. .

Also, by applying a negative potential to the human body,
The amount of ionized sodium and calcium in the circulating blood increases, producing an effect that alkalinizes the acidic human body, i.e., an ionic effect, resulting in stiff shoulders, headaches, insomnia, chronic constipation, and other allergic diseases, etc. It is also well known that therapeutic effects can be obtained against. (Potential Treatment Method) However, the actual situation is that the above-mentioned pine surge effect is performed separately by a massaging machine, and the potential treatment is performed separately by a potential treatment machine.

In addition, as one of the means to solve the above-mentioned problems, a group of protrusions are provided on the top surface of the diaphragm to suppress the vibrations caused by a weight eccentrically attached to the motor output shaft with respect to the diaphragm. It has also been proposed that a massaging machine installed to transmit electric potential can simultaneously obtain a pine surge effect and electric potential treatment by fixing the electrode of a negative potential generator to the end of the diaphragm ( (Japanese Patent Application Laid-Open No. 52-84881), this method of obtaining electrical coupling by directly fixing electrodes to the ends of the diaphragm has the disadvantage that vibration causes fatigue in the electrical coupling part. has. In particular, by converting the rotational motion of the motor into reciprocating motion via a crank mechanism, a sliding plate is provided inside the case body so that it can freely reciprocate, and the rods are moved oppositely along the reciprocating direction from both ends of the sliding plate. In a massaging machine in which the vibrator is installed at the tip of the rod in such a way that it can be moved in and out of the case body, the amplitude of the vibration is large, causing early fatigue in the electrical connection part. The problem is that the

It is slidably inserted in the direction. The sliding plate 10 is provided with a window hole 11 located approximately at the center thereof, and the above-mentioned crank pin 7b is provided in the window hole 11 so as to engage with the window hole 11. Further, rods 12, 12 are provided protruding from both the front and rear ends of the sliding plate 10 in the front and back direction, and a vibrator 1 is mounted at the tips of both rods 12, 12.
3 and 13 are screwed so that they can freely appear and retract from both the front and rear walls of the case body 3. The vibrator 13 consists of a mounting base 13a that is screwed onto the tip of the rod 12, a cover body 13b that is attached to the base 13a, and an elastic body 13c that is interposed between the base 13a and the cover body 13b. 13a, cover body 13
