This device has advantages such as being very convenient to handle because it is a uni-nod system.

By the way, since conventional devices of this type are unitized, they are often lost, and since conventional devices had a built-in battery, the uni-nod case had to be disassembled each time the battery ran out. I had to replace the battery.

[Purpose of the invention]

In view of the above-mentioned circumstances, it is an object of the present invention to provide a rechargeable performance promoting device set in which a treatment device unit can be stored so as not to be lost, and can be charged when stored. With the goal.

[Disclosure of the invention]

In order to achieve the above object, the present invention comprises a combination of a treatment device unit and a charger, and includes an antenna and a circuit for generating a high-frequency electromagnetic field from the antenna inside a unit case of the treatment device unit. , a rechargeable battery that drives the circuit, and a charging terminal exposed outside the case, and the charger charges the treatment device unit when it is set. A rechargeable blood circulation promoting device set, wherein the charger is provided with a case fitting recess shaped to fit the unit case of the treatment device unit, and the unit case is attached to the inner periphery of the opening of the recess. A rechargeable blood circulation promoting device comprising: a stopper that can be freely engaged and detached; and a contact terminal that contacts the charging terminal on the unit case side is exposed and arranged on the inner circumference of the recess. The set is the gist.

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

Figures 1 to 7 show an embodiment of the treatment unit A of the rechargeable blood circulation promoting device set according to the present invention, and Figures 8 to 14 show how the unit A is charged. I'm having trouble getting charger B. The treatment device unit A is charged by being stored in the charger B as shown in FIG. 8, and is removed from the charger B and attached to the body or to a body part such as clothing to promote blood circulation in the body. It has become. The treatment device unit I-A includes a disc-shaped unit case 1 made of plastic material. This unit case 1 is composed of a plate-shaped case body 2 that is worn on the body, and a case cover 3 that is located on the outside of the plate-shaped case body 2. The case body 2 has a circular opening in the center as a charging opening 4 that penetrates in the thickness direction, and a large number of ventilation grooves 5 are formed radially on the mounting surface (outer surface). A fitting groove 6 into which the outer peripheral edge 7 of the case cover 3 fits is formed on the outer circumference of the surface (inner surface) of the case body 2 corresponding to the case cover 3 side. A portion inside the inner protrusion 6a is a recess 8 for fitting the board. The case cover 3 has a thin spherical shape as a whole, with a high central portion from the center to about 1/2 of the radius and a gradually lower peripheral portion. The outer peripheral edge 7 of the case cover 3 fits into the fitting groove 6 of the case body 2, and in order to improve waterproofness, both of the outer peripheral edges 7 and 6.
The entire circumference is airtightly joined using an ultrasonic welder. In this case, a cylindrical engagement protrusion 9 is provided at the outermost edge of the case body 2 and protrudes very low upwards, and this engagement protrusion 9 is located on the outer periphery of the case cover 3. There is. A circular printed circuit board IO is fitted into the board fitting recess 8, and its outer circumferential portion is inserted between the outer circumferential portions of the case body 2 and the case cover 3. An O-ring 12 made of silicone rubber or the like is fitted into a ring groove 11 formed inside the outer peripheral edge 7 of the case cover 3, and this O-ring 12 is pressed against the outer peripheral part of the printed circuit board 10. The space between the case cover 3 and the printed circuit board 10 is airtight. This airtight structure portion, together with the welded joint portion, improves the waterproofness of the unit case 1.

As seen in detail in FIG. 5, on the printed circuit board 10, an IC circuit pattern constituting a high frequency generation circuit for generating an electromagnetic field is formed on the outer periphery of the surface on the side of the case cover 3 by a printing technique, IC circuit components 13 and LEDs 14 are arranged on the printed surface. A rechargeable battery 18 for driving the high frequency generation circuit is disposed inside the IC circuit pattern, and
First and second connecting fittings 15 and 16 electrically connected to the rechargeable battery 18 are also provided. The LED 14 is designed to repeatedly blink when the treatment device Uniso A is generating a high-frequency electromagnetic field, and to extinguish smoke in other cases, so that the status can be determined from the outside. Therefore, a see-through operation confirmation window 17 is provided at a location corresponding to the LED 14 on the case cover 3. This operation confirmation window 17 is formed in such a way that only the area corresponding to the window 17 remains transparent when opaque printing is applied to the surface of the case cover 3 formed of a transparent resin material. . On the other hand, on the surface of the printed circuit board 10 on the side of the case body 2 (the side to which it is attached to the body or other body part), as shown in detail in FIG. 2 charging terminals 21 are arranged, and an antenna 23 is arranged on the outer periphery of the charging terminals 21.
Each of them is electrically connected to the IC circuit pattern via a through hole 22. These charging terminals 20.2
1 and the antenna 23 are all formed by printing techniques. The unit-side first charging terminal 20 is located at the center of the printed circuit board 10, and the unit-side second charging terminal 21 is located concentrically around its outer periphery. The unit-side first charging terminal 20 is completely circular, but the unit-side second charging terminal 21 is C-shaped, extending approximately 270 degrees in the circumferential direction. In this way, since the unit-side second charging terminal 21 is formed not in a perfect ring shape but in a C-shape, high-frequency eddy current loss generated by the antenna 23 is prevented from occurring. The unit-side first charging terminal 20 and the unit-side second charging terminal 21 are configured so that they will not break due to a short circuit even if the unit case is attached to the body while taking a bath or sweat is attached to the unit case. The antenna 23 is formed in a spiral shape so as to surround both charging terminals 20 and 21 provided at the center of the printed circuit board 10 from the outer periphery. In this way, the antenna 23 can be provided for a long time using a considerably large space on the printed circuit board 10, so that a larger output can be obtained with the same amount of current as before. Conversely, since less current is required to obtain the same output, power can be saved and the life of the rechargeable battery 18 can be extended. This antenna 23 is placed on the mounting surface side, and is formed extremely thin together with the charging terminal 20.21 using a printing technique, so that the electromagnetic field is transmitted from a position close to the skin surface 30 of the body. It can be applied to the affected area more efficiently.

A protective sheet 25 for waterproof insulation is provided on the surface of the printed circuit board 10 on the side of the case body 2 so as to be sandwiched between the case body 2 and the printed circuit board 1O. This protective sheet 25 has a circular first through hole 26 in the center, and an arcuate second through hole 27 on the outer periphery that is similar to and slightly smaller than the unit side first charging terminal 20.
It is equipped with The protective sheet 25 has double-sided adhesiveness,
The first through hole 26 is located concentrically at the center of the circular first charging terminal 20 on the unit side, and the second through hole 27 is located at the center of the width of the second charging terminal 21 on the unit side, −
One side is attached to the case body 2 by the first adhesive 28, and the other side is attached to the case body 2 by the first adhesive 28.
They are each bonded onto the printed circuit board 10 with an adhesive 29. The surface of the protective sheet 25 on the case body 2 side is adhered to the surface of the substrate fitting recess 8 of the case body 2 with a first adhesive 28 . In this way, all the through-hole holes 22... are closed by the protective sheet 25, ensuring waterproofing between the printed circuit board 10 and the case body 2, preventing sweat and water from entering the case, and preventing various germs from entering the case. This also prevents the occurrence of. The first through hole 26 and the second through hole 27 of the protective sheet 25 are connected to the first through hole 26 and the second through hole 27 on the unit side of the printed circuit board 10.
Since the protective sheet 25 is not adhered to the stepped portion of each copper foil pattern forming the charging terminal 20 and the second charging terminal 21 on the unit side, but to the flat surface inside thereof, the protective sheet 25 is not likely to lift up or peel off. There is no such problem, and the waterproof effect is more reliable.

On the side of the case body 2 that is attached to the skin surface 30,
A mounting member 31, which is made of a foamed polyurethane material and is breathable and deforms according to the shape of the skin surface 30 to prevent mechanical rash, is attached to the underwear so as to be replaceable. This mounting member 31 has a circular ventilation hole 32 in its center.
It is said to be a thin ring. Adhesive 35.35 is applied to both the front and back surfaces of the mounting member 31, one of which is pasted on the side of the case body 2 on the side of the ventilation groove 5, and the other is pasted on the skin surface 30 or other attachment site. It will be done. Each adhesive 3
5 is provided with a ventilation hole 34. Note that since the vent 32 at the center of the mounting member 31 is formed larger than the charging opening 4 of the case body 2, the adhesive 35 is far away from both charging terminals 20, 21. The attachment member 31 is designed to be difficult to adhere to the skin surface 30, etc., thereby preventing poor contact between the charging terminals 20 and 21 due to adhesion of the adhesive. , but there is a ventilation hole 3 in that plane.
2 is formed, the steam and body heat due to sweat once enters the vent hole 32 and is discharged to the outside of the unit case 1 in the radial direction through the vent groove 5 and the mounting member 31. In addition, these vapors are released in the outer diameter direction through the ventilation holes 34 and the ventilation holes of the mounting member 31 itself, or
It is also adapted to be discharged from the mounting member 31 through the ventilation groove 5 to the outside of the unit.

In this way, steam and body heat are effectively eliminated through many routes, and rashes are more effectively prevented. In addition, since the mounting member 31 is equipped with a relatively large ventilation hole 32 in the center, the mounting member 3
Although the adhesion area to the skin surface 30 of the mounting member 31 is smaller, it is only the outer circumferential side of the mounting member 31 that is actually involved in mounting, so even if such a vent is provided, the mounting will not be easy. There is no shadow 8 that is as big as the difference in power. The ventilation m5 reduces the contact area between the case body 2 and the mounting member 31. Therefore, when it becomes necessary to replace the mounting member 31, it is very advantageous to use a fingernail or the like to intervene in the ventilation groove 5 to remove the mounting member 31, since the mounting member 31 can be easily peeled off.

The treatment device unit A is set in a charger B, which will be described below, and is charged.

Charger B consists of a charger storage cover 40 and a charger body 41.

The charger storage cover 40 is made of a soft resin material in which a back sheet 43 having an insertion ring 42 and a front cover 44 are integrally molded to be openable and closable. Said back sheet 43
A charger main body 41 is attached to the main body 41 so that one end thereof is inserted through an insertion ring 42. A rectangular insertion sheet 45 with two open sides is provided on the inside of the front cover 44, and a mounting member set seal 46 consisting of a release sheet to which a plurality of mounting members 31 are attached is attached to this insertion sheet 45. It is designed to be inserted and removed freely between the front covers 44. 'Each mounting member 31 has its back adhesive surface directly attached to the release sheet 46, and its front adhesive surface is provided with an individual peel-off sheet (release sheet) 47, and after being peeled off from the sticker 46, By peeling off this removable sheet 47, it can be attached to the back surface of the unit case 1. The charger main body 41 is detachably attached to the back sheet 43 by a fastener (not shown). This charger main body 41 includes a lower case 51
This is achieved by aligning the upper case 52 and upper case 52 vertically and fastening them together with screws 53. The lower case 51 is equipped with a removable battery cover 54, and if this is removed, the battery receiver 5 of the upper case 52 will be opened.
A dry cell (charging power source) 56 housed in the battery 5 can be attached and detached and replaced.

The upper case 52 has a slightly higher and flat surface on the negative side (the left side in FIG. 1O), but has a slightly concave shape on the other side. The center portion of this recessed portion is recessed into a cylindrical shape, and the recessed portion is used as a charging case fitting recess 57 . This charging case fitting recess 57 includes a cylindrical peripheral wall 57a and a circular bottom wall 57b, and the peripheral wall 57
A button set opening 58 is arranged in one example part of a, and a -1 spring window 59 is arranged in the other side so as to face each other.

Inside the button set opening 58, there is an operation recess 60a at the top.
A push button 60 having a guide shaft 60b protruding from its lower part is fitted into the push button 60.
It is guided by the walls of the lower case 51 and the upper case 52 and is movable up and down. This push button 60 is always urged upward by a return spring 61, and is normally locked with a catch on the upper case 52 side. The end surface of this push button 60 on the charging case fitting recess 57 side is the charging case fitting recess 57.
Although it is formed to have a curved surface continuous to the cylindrical surface of 7, only the upper edge thereof slightly protrudes toward the charging case fitting recess 57 to form an arc-shaped first stopper 62. This first stopper 26 forms a first retaining groove 64 in which the retaining protrusion 9 (see also FIGS. 1 and 2) of the unit case l is fitted between it and the outer peripheral end of the bottom wall 57b. are doing. The peripheral edge of the opening end of the case fitting recess 57 of the first stopper 62 forms a tapered first guide surface 63 whose diameter increases from the inside to the outside of the recess.

On the other hand, the center portion of the engagement push spring 66 faces the spring through hole 59 so as to move forward and backward in the engagement direction of the charging case fitting recess 57 . This engagement push spring 66 is formed as a strip-shaped piece using a plastic material, and the fulcrum portions 67 at both ends are supported by the upper case 52 as shown in FIG. It is designed to be able to be elastically deformed. A second engagement groove 68 into which the engagement protrusion 9 of the unit case 1 is fitted is provided in the center part.
is formed into a U-shaped cross section, and the second engagement groove 68
A second stopper 69 is formed to protrude from the upper part. Like the first stopper 62, this second stopper 69 normally projects a little into the charging case fitting recess 57. This second stopper 69 is formed in an arc shape when viewed from above, and has an inverted conical surface (tapered surface) on the upper side.
A second guide surface 70 is formed as a part of the second guide surface 70 .

An elliptical protrusion 73 is formed on the bottom wall 57b of the charging case fitting recess 57, and three spring through holes are formed at the location where the protrusion 73 is located so as to penetrate vertically. 4.75.
75 is formed. The center spring through hole 74 is located at the center of the charging case fitting recess 57 and is located at the center of the charging case fitting recess 57 .
．． 75 are arranged on both sides thereof, offset from each other by 180 degrees.

The center spring passage hole 74 has a contact terminal 76, and the spring passage holes 75 and 75 on both sides have contact terminals 77 and 77, respectively.
is inserted vertically and protrudes upward. These contact terminals? 6, 77, and 77 are electrically connected to the printed circuit board 78 attached to the bottom of the upper case 52, and are in contact with the charging terminals 20, 21 when the unit case 1 is attached, and at this time, It also functions to push the unit case l upward.

Note that a charging indicator lamp 79 is provided on the top surface of the upper case 52.
is provided.

The unit case l is attached to and detached from this charger in the following manner. In other words, when the unit case l is pushed into the charging case fitting recess 57 with its recharging terminal 20. 66 is elastically deformed so as to be pushed away. As a result, the second stopper 69, which had previously had a gap at the back, is pushed away and retreats toward the back wall 71, and the retaining protrusion 9 of the unit case 1 is inserted between the first stopper 62 and the second stopper 69. will be able to pass. The engagement protrusion 9 of the unit case 1 fits into the first engagement groove 64 and the second engagement groove 68 through the space therebetween.
It comes to be engaged with these. This engagement is achieved by the engagement push spring 66 moving toward the recess 57 due to its elastic return action. In this way, at the same time that the unit case 1 is set in the charging case fitting recess 57, the unit side first charging terminal 20 exposed on the lower surface of the unit case 1 comes into contact with the contact terminal 76 of the charger, And, the unit side second charging terminal 21 is the contact terminal 7 of the charger.
7. The charging mode is completed by touching any one of 77.

This charging position is also the storing position of the unit case l. To reach this state, all that is required is to hold the unit case 1 with one hand and push it into the charging case fitting recess 57. In this state, since the unit-side first charging terminal 20 and the contact terminal 76 are both located on the center, they are always reliably aligned and electrically conductive regardless of the orientation of the unit case 1. On the other hand, the unit side
Regarding the charging terminal 21 and the contact terminal 77, the contact terminal 77
If the second charging terminal 21 on the unit side is located in only one place, even if the second charging terminal 21 on the unit side is C-shaped, depending on the orientation of the unit case 1, the second charging terminal 21 on the unit side will be connected to the second guide surface 7.
Sometimes it does not match 0. However, the contact terminal 77 is
Since the pairs are arranged 180 degrees apart from each other, and the second charging terminal 21 on the unit side is provided in a C-shape with a larger angle, no matter what direction the unit case 1 is, at least one The unit-side second charging terminal 21 comes into contact with the contact terminal 77 . As a result, the unit side second charging terminal 21 and the contact terminal 77
Electrical continuity is also always ensured. Furthermore, in the charging state, the unit case 1 is not simply engaged with the first engagement groove 64 and the second engagement groove 68, but is always engaged with the second engagement groove due to the elastic force of the engagement push spring 66. It is pushed toward the matching groove 68, thereby ensuring that the engaged state is maintained and charging is performed reliably.

To take out the unit case l from the charger body 41.
Just press the push button 60. In other words, when you press the push button 60, the first engagement groove 64 lowers and engages the engagement protrusion 9 of the unit case l like a cam in the direction of the push spring 6G. Push back to. As a result, the engagement push spring 66 retreats, and the first engagement groove 64 descends and climbs over the engagement protrusion 9. At this time, contact terminal 7
Since the elastic force of 6°77 acts as a pushing force on the lower surface of the unit case 1, the unit case 1 pops out from the push button 60 side and rests on the first guide surface 63. When the push button 60 is released from this state, the push button 60 returns while lifting one end of the unit case 1 due to the return force of the return spring 61. The unit case 1 thus constructed has the engaging protrusion 9
It can be easily removed by lifting it with your finger or nail. All operations in between can be performed easily and quickly with one hand, and all that is left is to attach the mounting member 3.
1 to the back of the unit case L, it can be worn on the body.

Each circuit configuration of these treatment device unit) A and charger B is
As shown in Figure 5. In other words, the treatment device unit)
Inside A, there is a charging voltage detection circuit 81 and an operation control circuit. 11 circuit section 82 is composed of rc. These charging voltage detection circuit 81 and operation control circuit section 82 are used to oscillate and stop the electromagnetic waves of the treatment device unit A, turn on and off the LED 14, and also perform charging when the treatment device unit A is set in the charger B. Controls are performed to turn on and off the charging indicator lamp 79 of the battery B, and to prevent overcharging of the rechargeable battery 18 based on voltage detection between the charging terminals 20 and 21. As shown in FIG. 16, the operational flow of these circuit configurations is shown, while the rechargeable battery 18 has a power supply voltage, electromagnetic waves are radiated from the antenna 23 through the oscillation circuit section 83, and the antenna 23 is in an operating state. The LED 14 is turned on by an LED lighting circuit to notify the user. this is,
The operation is confirmed through the operation confirmation window 17 of the unit case 1. When it is recognized that the electromagnetic wave oscillation has stopped by turning off the LED 14, the treatment device unit 8 can be set in the charger B and charged.

When the LED 14 is lit and the electromagnetic waves are oscillating when the charger B is set, the charging voltage detection circuit 81 is built in the treatment device unit A side, so this circuit 8
1 is connected to charger B by detecting the voltage between charging terminals 20 and 21.
It detects that there is a voltage input from the device, and stops the oscillation of electromagnetic waves through the operation control circuit section 82, which is also built in the treatment device unit I-A, and turns off the LED 14. This prevents wasteful power consumption. When charging of the rechargeable battery 18 of the treatment device Unison A starts from the dry battery (charging power source) 56 through the contact terminals 76.77 and the charging terminals 20.21, the operation control circuit section 82 displays the charging status of the charger B. It instructs the lamp 79 to turn on to notify the user that charging is in progress. When it is detected that the voltage of the rechargeable battery 18 is higher than the specified value or that the charging time has exceeded the specified value, the charging of the rechargeable battery 18 is stopped to prevent overcharging, and the charging of the charger B is stopped. The indicator lamp 79 is also turned off to notify the user that charging is complete.
