Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a perspective view of the electric massager in which the subject innovation device is implemented, Figure 2 shows an enlarged cross-sectional view of the main portion of the electric massager equipped with the subject innovation device.

According to this, the handle 11 is provided on both sides, and the hollow body of the hollow body (1) is formed on the one side of the upper surface of the access hole 12 is exposed part of the upper end of the actuator (4);

A motor (2) installed in the main body (1) in a horizontal direction and performing a rotation operation when there is electricity supply;

An eccentric rod 31 coupled to the shaft 21 of the motor 2 is protrudingly formed at one side, and a shaft rod 32 fitted to the bearing 7 of the actuator 4 is protrudingly formed at the other center. A cam 3 for converting the rotational force of the motor 2 into a linear motion of the actuator 4;

It is connected to the cam 3 through a bearing 7 having a rod shape having a predetermined diameter and length and fixedly installed in the settling groove 41 at the lower end thereof, and the upper end thereof is moved outward through the entrance hole 12 of the main body 1. An actuator (4) for performing a linear upward and downward movement during rotation of the motor (2) in an exposed state;

It is provided with a pressing protrusion 51 and the like is detachably installed on the upper end of the actuator (4) when the actuator (4) performs a linear movement by the rotation of the motor (2) to acupuncture points and meridians of the human body Massage rods (5) to beat like acupressure;

The bottom part is detachably fixed to the entrance hole 12 of the main body 1 and the upper end part is repeatedly contracted and expanded during the linear motion of the actuator 4 in the state fixed to the upper part of the actuator 4. In addition, in the electric massager consisting of a bellows-type closure 6 of rubber material for preventing foreign matter from entering through the entrance hole 12 of the main body 1,

The hooking protrusions 42 are formed by horizontally protruding a pair of disc-shaped locking protrusions 42 at a slightly lower side from the upper end of the actuator 4 at intervals slightly wider than the thickness of the bellows closure 6. It is characterized in that the inner circumferential surface of the upper hole 61 of the bellows closure 6 is inserted and fixed between the gaps formed between them.

The present invention constructed as described above has a rubber material at a position slightly biased downwardly from its upper end (ie, directly below the lower end of the massage rod 5) when injection-molding the rod-shaped actuator to have a predetermined diameter and length. By forming a pair of disc-shaped locking projections 42 horizontally at intervals slightly wider than the thickness of the bellows closure 6, the bellows closure 6 is opened and closed ( 12) and the lower outer surface thereof is inserted and fixed around the access hole 12 of the main body 1, and the inner circumferential surface of the upper hole 61 is formed between the engaging protrusions 42 when installed between the actuator 12 and the actuator 4. It fits between the gaps and is fixed.

That is, the bellows closure 6 made of rubber material prevents foreign matter from entering through the entrance and exit 12 of the main body 1 while repeating the contracting and expanding movement during the linear movement of the actuator 4. The bottom part is detachably fixed to the entrance hole 12 of the main body 1, and the upper end part is sandwiched between the locking projections 42 of the disc shape formed on the upper part of the actuator 4 so that the separate bonding work is performed. Since the assembly of the bellows type closure 6 is not only very simple, but adhesives are not visible to the outside of the actuator 4 at all, the productability of the product is improved and the product can be used for a long time. Due to the damage to the seal (6), even if you want to replace a new one, no need to remove the adhesive portion can be replaced simply.

At this time, the diameter of the upper hole 61 of the bellows closure 6 is smaller than the diameter of the outer circumferential surface of the locking projection 42 (in other words has an inner circumferential surface corresponding to the outer circumferential surface of the actuator 4) Since the LASIK 6 is formed of a rubber material having excellent tensile and elastic force, a part of the upper end of the actuator 4 is inserted into the upper hole 61 of the bellows closure 6 and then the actuator ( 4) When the bellows-type closure 6 is pulled downward while pushing upwards, the upper hole 61 of the bellows-type closure 6 is extended by the locking protrusion 42, so that the locking protrusion 42 After passing through the hole 61, the upper hole 61 of the bellows closure 6 is returned to its original state by the restoring force of the bellows, so as to the gap between the engaging projections 42 as shown in FIG. It stays plugged in.

Of course, when you want to separate the bellows-type closure 6 from the actuator 4, the separation operation is performed in the same manner as described above.

On the other hand, when the power switch (not shown) to operate the electric massage ball applied to the present invention "on" the motor 2 is rotated, the eccentric of the cam (3) on the shaft 21 of the motor (2) Since the rod 31 is coupled, when the motor 2 rotates, the cam 3 performs an eccentric circular motion that draws a large circle in an up and down direction.

At this time, since the bottom of the actuator 4 is in a state of being connected to the shaft rod 32 protruding from the center point of the other side of the cam 3 through the bearing 7 fixed on the settling groove 41, the cam In the eccentric circular motion of (3), the bearing 7 rotates itself in the settling groove 41 of the actuator 4 to transmit the rotational force according to the eccentric circular motion of the cam 3 to the actuator 4. Therefore, the linear motion of raising and lowering directly below the actuator 4 is performed, and the bellows closure 6 repeats the contracting and expanding movement during the linear movement of the actuator 4.

Therefore, the massage rod (5) having a pusher protrusion (51) and the like is detachably attached to the upper end of the actuator (4) when the actuator (4) performs a linear movement by the rotation of the motor (2). The linear motion is performed with the actuator 4.

Therefore, when the user of the electric massager grasps the handle 11 of the main body 1 and places the massage rod 5 on the acupuncture points and the meridians of the human body, the acupressure protrusions 51 of the massage rod 5 press the portion of the pressure. As it is beaten so that the stiff muscles are released, as well as blood circulation is made smoothly to promote metabolism.

As described above, according to the present invention, by forming a pair of disc-like locking projections horizontally at a position slightly lower from the upper end of the actuator so that the inner circumferential surface of the upper hole of the bellows closure is fitted and fixed between the locking projections, The bellows type sealing device which prevents the inflow of foreign substances such as dust into the main body can be assembled more easily, which can lower the production cost of the product and improve the productability of the product. If the seal is damaged, it is a very useful design such that it can be easily replaced with a new seal.
