Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses the suction force of a striking tool, particularly a plunger generated by passing a current through a solenoid coil, to strike the skin of the back etc. with a striking body such as a disk. This relates to a hammering tool for hitting.

Due to the nature of the beauty tool, the beating tool is pressed against the skin of a person's back and hits the skin with the beating body, so it has a moderate hitting force and is relatively small and lightweight. desired.

Conventionally, this type of hitting tool used a spring force to hit the skin of a person's back with a disk-shaped hitting body, and used an electromagnetic force such as a solenoid to release the skin. For this reason, a fairly strong spring is required to hit the skin with the disk-shaped hitting body, and the solenoid must be large to accommodate this force, and the other mechanisms must also be made sturdy. However, there was a problem in that it was structurally strong and the overall size of the beating tool was large. Furthermore, since spring force was conventionally used to strike the skin, there was a problem in that it was relatively difficult to adjust the striking force. Furthermore, if a solenoid is used to perform the beating operation, it is necessary to correctly match the direction of the driving force of the solenoid with the direction of the beating body. That is, if the matching is not obtained, the striking body will undesirably come into contact with the inside of the space guide, producing undesired noise, and furthermore, causing trouble in the reciprocating movement of the striking body.

The present invention aims to solve the above problem. The present invention will be described in detail below with reference to the drawings.

In the beating tool of the present invention, a right-handed person can hold the handle 1 on the lower right side in the figure with his left hand, and hold the handle 2 on the upper left side in the figure with his right hand.
, and press the cylindrical space guide 3 on the left side of the figure against the skin of a person's back.
Then, by turning on the power switch 4 provided at the lower end of the handle 1 on the lower right side of the figure, the disc-shaped beating body 5 inside the cylindrical space guide 3 vibrates from side to side as shown by the arrow. As the skin is struck, the temperature blown out from the hole 3-1 of the space guide 3 is applied by the cover 3-2 as shown by the arrow.
The direction is changed so as to wrap around the left end of the space guide 3 to warm the skin.

In this way, the slapping tool, which is a beauty device, can smack the skin while warming the skin with hot air, and because it is pressed against the skin by a person's hand, it has a moderate slapping force. Something relatively lightweight and efficient is required.

Therefore, in the present invention, in order to strike the beating body 5 against the skin, the suction force of the plunger is used, which makes it easy to obtain a strong force and whose strength can be made variable. A small spring is used because it does not require a very strong force to release it, and it is sufficient to simply reset the striking body 5, shaft 8, etc. By adopting such a configuration, the present invention has the following features:
Compared to conventional systems that hit the skin with a beating body using the force of a strong spring, the structure does not need to be as sturdy, allowing the device to be made more compact, and the strength of the beating can be freely controlled. becomes possible.

The solenoid coil 6 shown in the figure is a solenoid coil wound around a "Ja"-shaped core, and the periphery of the core is covered with a magnetic material to form a magnetic circuit. A space is provided in a part of the space shown in the figure, and a movable plunger 7 made of a magnetic material is installed in this space.

The plunger 7 is fixed to the shaft 8, and when a current is applied to the solenoid coil 6, the plunger 7 is drawn into the gap ◯◯ of the solenoid coil 6, and the shaft 8 is moved to the left. At this time, the beating body 5 attached to the left end of the shaft 8 hits the skin of the person's back, etc. The strength of this hitting can be determined by varying the strength of the current flowing through the solenoid coil 6. By doing so, you can freely adjust the settings. In addition, in order to suppress the vibration and sound generated when the plunger 7 is drawn into the cavity ○a, the plunger stopper 7-1 fixed to the shaft 8 and the opposing surface of this plunger stopper 7-1 are provided. Buffer rubber 7 is attached to the yoke surface of the solenoid coil 6 located at
-2 is attached.

On the other hand, by cutting off the current flowing through the solenoid coil 6, the attraction force generated in the plunger 7 disappears, and the fixing tool 9-1 is attached to the shaft 8.
Fix one end of the return spring 9 through the
The shaft 8 is moved rightward by the tension of the return spring 9 whose other end is fixed to the frame 10. As a result, the beating body 5 attached to the left end of the shaft 8 is separated from the skin.

In addition, in order to strike the skin of a person's back with the striking body 5 by the suction force of the plunger 7, a shaft 8 is attached to the plunger 7, and the left end of the striking body 5 is used to strike the skin of a person's back. In the case of a structure in which the striking body 5 is attached, the suction force of the plunger 7 does not necessarily act correctly in the direction of the central axis of the shaft 8, and the shaft 8 is driven while swinging undesirably.

Therefore, in this embodiment, bearings 11-1 and 11-2 are provided on both sides of the solenoid coil 6, respectively, to prevent the shaft 8 from swinging undesirably. That is, the shaft 8 passes through the inside of the plunger 7 and is supported by the bearings 11-1 and 11-2 on both sides.

Providing the non-magnetic shaft 8 penetrating the inside of the solenoid coil 6 in this way reduces the opposing area between the plunger 7 and the yoke of the solenoid coil in the air gap ○a. Although the resulting suction force may be weakened, unless the shaft 8 is prevented from moving undesirably, the beating body 5 will not be able to beat the skin surface rhythmically. In this case, the non-magnetic shaft 8 is made of a lightweight material such as aluminum alloy, so that the energy required to drive the striking body 5 is small, and even when the striking body 5 is repeatedly vibrated at high speed, it is sufficient. It becomes something that can be followed.

Next, the warm air blown out from the beating tool of the present invention will be explained.

A blower fan 13 fixed to the shaft of the motor 12
As the is rotated, air is sucked in from the right side of the main body as shown by the arrow, passes outside the solenoid coil 6, is heated by the heater 14, passes inside the space guide 3, and enters the hole 3- of the space guide 3. 1, the direction of the hot air is changed as shown by the arrow by the cover 3-2 of the space guide 3, and hot air is blown out so as to wrap around the beating body 5. As a result, the skin of the person's back is warmed by the hot air and is also beaten by the beating body 5.

At this time, the strength and speed of the force of the striking body 5 can be determined by adjusting the strength control knob 15 and the striking speed control knob 16 attached to the lower end of the lower right handle 1 in the figure. This is done by controlling the voltage supplied to the solenoid coil 6 using the solenoid drive circuit board 17. The warmth of the hot air can be adjusted by adjusting the heater control knob 18 attached to the upper end of the upper left handle 2 in the figure, and controlling the heater 14 by the heater control circuit board 19 inside the handle 2.
This is done by controlling the voltage supplied to the
Further, the striking body 5 is magnetically attracted to a striking body receiver 5-1 fixed to the axis of the shaft 8. Therefore, in order to convert the contact portion of the striking body 5 into a smaller one, the striking body 5 is rotated, for example, by 180 degrees with respect to the striking body receiver 5-1, and the same magnetized magnetic poles are made to face each other. In this case, no magnetic adsorption force is generated, but rather a repulsive force acts, so that the striking body 5 is easily struck against the striking body holder 5.
-1 can be removed.

As explained above, according to the present invention, a striking body is struck against the skin of a person's back using the suction force of a strong and variable-strength solenoid type plunger, while the spring force is used to strike the body against the skin of a person's back. Since the striking body is configured to be moved away from the skin, the overall size of the device can be made relatively smaller compared to conventional systems that use strong springs, and the strength of the striking can be reduced. It has a configuration that can be changed arbitrarily, so to speak, continuously.
