Description

[Detailed description of the invention] (Technical field〕 The present invention relates to a rechargeable blood circulation promoting device set.

[Background technology]

In order to recover from stiff shoulders and muscle pain, it is effective to promote blood circulation by applying electromagnetic waves to specific parts of the body.

Therefore, a blood circulation promoting device was developed for this purpose. This blood circulation promoting device is used by being directly attached to areas where blood circulation is stagnant, such as stiffness. Recently, such a device has been constructed into a single unit by incorporating a high-frequency generation circuit, a rechargeable battery to drive it, and an antenna that forms an electromagnetic field by the action of the circuit into a case that is attached to the affected area. This device has the advantage of being very convenient to handle because it is unitized.

By the way, since the above-mentioned conventional device is of the type where the battery is replaced, it is not only troublesome to replace it, but also because it is only the device, there is a risk that it may be lost. Therefore, a device equipped with a charger that houses the blood circulation promoting device and also charges it has been proposed, but this device had a switch to turn the oscillation on and off on the blood circulation promoting device itself. When the accelerator is placed on the body in the ON state, there is a risk that the switch may be unexpectedly switched to the OFF state due to friction from clothing or other external force. Also, since it was equipped with a switch, I often forgot to turn it off after use, causing the battery to run out.

[Purpose of the invention]

In view of the above-mentioned circumstances, it is an object of the present invention to provide a rechargeable blood circulation promoting device set that does not unexpectedly stop generating an electromagnetic field during use and does not consume unnecessary power after use. With the goal.

[Disclosure of the invention]

In order to achieve the above object, the present invention consists of a combination of a treatment device unit and a charger, and the treatment device unit includes an antenna and a circuit for generating a high-frequency electromagnetic field from the antenna inside the unit case. , and a rechargeable battery that drives the same circuit, this treatment device unit,
The treatment device unit is attached to the attachment site by the attachment means to promote blood circulation in the body by the electromagnetic field, and the treatment device unit is removed from the attachment site and set in a charger and removed from the treatment device unit. A rechargeable blood circulation promoting device set in which the rechargeable battery is charged through an exposed charging terminal, the treatment device unit is of a type without a switch, and the unit is set in a charger. The gist of the present invention is a rechargeable blood circulation promoting device set that is configured so that oscillation for generating an electromagnetic field sometimes stops.

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

FIGS. 1 to 7 show an embodiment of the treatment device unit A of the rechargeable blood circulation promoting device set according to the present invention, and FIGS. It's raining on 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 looks like this. The treatment device unit 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 on the mounting surface (outer surface).
are formed radially. A fitting groove 6 into which the outer peripheral edge 7 of the case cover 3 is fitted is formed on the outer peripheral part of the surface (inner surface) of the case body 2 corresponding to the case cover 3 side,
A portion inside the inner protrusion 6a forming the fitting groove 6 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, the entire circumferences of both 6 and 7 are airtightly joined by ultrasonic welding. . In this case, a cylindrical locking protrusion 9 is provided at the outermost edge of the case body 2 and protrudes very low toward the top. There is.

A circular printed circuit board 10 is fitted into the board fitting recess 8, and its outer periphery is sandwiched between the outer peripheries of the case body 2 and the case cover 3. 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. and printed circuit board 1
The space between 0 and 0 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. Inside the IC circuit pattern, a rechargeable battery 18 for driving the high frequency generation circuit is disposed, and first and second connecting fittings 15 and 16 electrically connected to the rechargeable battery 18 are also disposed. has been done. The LED 14 is
When the treatment device unit) A is generating a high-frequency electromagnetic field, the light flashes repeatedly, and otherwise it turns off.In order to be able to determine the status from the outside, the case cover is A transparent operation confirmation window 17 is provided at a location corresponding to the three OLEDs 14. 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 case body 2 side (the side to be attached to the body or other body part),
As seen in detail in FIG. 5, a first charging terminal 20 on the unit side and a second charging terminal 21 on the unit side are arranged in the central part, and an antenna 23 is arranged in the outer periphery of the unit, with a through hole 22 in each. It is electrically connected to the IC circuit pattern via. These charging terminals 20.
21 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 a recharging terminal 20.21 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 by utilizing 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, it requires less current to obtain the same output, so
Power can be saved and the life of the rechargeable battery 18 can be extended. This antenna 23 is placed on the wearing surface 1, and is formed extremely thin together with the charging terminal 20, 21 using a printing technique.
It can be applied to the affected area more efficiently from a position closer to the body.

A protective sheet 25 for waterproof insulation is provided on the surface of the printed circuit board IO on the case body 2 side so as to be sandwiched between the case body 2 and the printed circuit board 10. 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.
Each of them is bonded onto the printed circuit board 10 with an adhesive 29. The surfaces of the two case bodies of the protective sheet 25 are adhered to the surfaces of the board fitting recesses 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 IO.
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 that is breathable, such as a foamed polyurethane material, and can be deformed according to the shape of the skin surface 30 to prevent mechanical rash, is attached in a detachable and replaceable manner. 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. It is difficult to adhere to these terminals. This prevents poor contact between both charging terminals 20 and 21 due to adhesion of the adhesive. The mounting member 31 is adapted to adhere to the skin surface 30, etc., and there is a ventilation hole 3 in the surface.
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 configured to be discharged from the mounting member 31 through the ventilation groove 5 to the outside of the unit case.

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 3o of the mounting member 31 is reduced, since only the outer peripheral side of the mounting member 31 is actually involved in mounting, even if such a vent is provided, the mounting will not be easy. There is no significant difference in power. The ventilation groove 5 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. A charger main body 41 is attached to the back sheet 43 so that one end thereof is inserted through the 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. Front cover 4
It is designed to be inserted and removed freely between the two. Each attachment member 31 has its continuous 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 seal 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 is constructed by aligning a lower case 51 and an upper case 52 vertically and fastening them to each other with screws 53. The lower case 51 is provided with a detachable battery cover 54, and by removing this, a dry battery (charging power source) 56 housed in a battery receiver 55 of the upper case 52 can be attached and detached.

The upper case 52 has a slightly high and flat surface on the negative side (left side in Figure 1O), but has a slightly concave surface on the other side.
It is formed in the shape of 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.
A button set opening 58 is arranged in one part of 7a, and a 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 bushing button 60 having a guide shaft 60b protruding from its lower part is fitted, and this bushing button 60 has the following features:
It is guided by the walls of the lower case 51 and the upper case 52 and is movable up and down. This bush 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 the charging case fitting recess 57 of this button 60 is the charging case fitting recess 5.
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 1 is fitted between the first stopper 26 and the outer peripheral end of the bottom wall 57b. are doing. A first guide surface 63, which is a part of an inverted conical surface (tapered surface), is formed on the upper part of the first stopper 62.

On the other hand, the center portion of the retaining bushing 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 retaining bushing 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 a second guide surface 70 that is a part of an inverted conical surface is formed on the upper side thereof.

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. When these contact terminals 76, 77, 77 are electrically connected to the printed circuit board 78 attached to the bottom of the upper case 52, they contact the charging terminals 20, 21 when the unit case l is attached. 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 1 is attached to and detached from this charger in the following manner. In other words, when the unit case 1 is pushed into the charging case fitting recess 57 with both charging terminals 20 and 21 facing down, one end of the unit case 1 passes through the second guide surface 70 to the retaining bushing spring. 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 engagement 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 passes through therebetween and fits into the first engagement groove 64 and the second engagement aSS,
It comes to be engaged with these. This engagement is achieved by the engagement bush spring 66 moving toward the recess 57 due to its elastic return action. In this way, at the same time that the unit case l 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
Even if the second charging terminal 21 on the unit side 7) is C-shaped, depending on the orientation of the unit case l, the second charging terminal 21 on the unit side may be located on 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 l is in, 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 bushing spring 66. It is pushed toward the matching groove 68 side, thereby ensuring that the mating state is maintained and charging is performed reliably.

To take out the unit case 1 from the charger body 41,
Simply press the button 60.

In other words, when the button 60 is pressed, the first engagement groove 64
lowers and pushes the engagement protrusion 9 of the unit case 1 back toward the engagement bushing spring 66 like a cam. As a result, the locking bushing spring 66 retreats, so the first locking groove 66
4 climbs over the retaining protrusion 9 while descending. At this time,
Since the elastic force of the contact terminals 76 and 77 acts as a pushing force on the lower surface of the unit case 1, the unit case 1 jumps out from the bushing button 60 side and reaches the first guide surface 6.
3. It comes to rest on top. When the bushing button 60 is released from this state, the bushing button 60 returns to its original state while lifting one end of the unit case l due to the return force of the return spring 61. Unit case 1 looks like this,
It can be easily removed by placing a finger or nail on the engaging protrusion 9 and lifting it. All operations during this time can be performed easily and quickly with one hand (1).All that is left is to attach the mounting member 31 to the back of the unit case (1) to attach it to the body.

Each circuit configuration of these treatment device unit A and charger B is
As shown in Figure 5. That is, in the treatment device unit A, a charging voltage detection circuit 81 and an operation control circuit section 82 are provided.
is composed of IC. These charging voltage detection circuit 81 and operation control circuit section 82 not only oscillate and stop the electromagnetic waves of the treatment device unit A and turn on and off the LED 14, but also control the charger when the treatment device unit A is set in the charger B. The charging indicator lamp 79 of B turns on and off, and the rechargeable battery 18 is based on the voltage detection between the charging terminals 20 and 21.
Performs various controls to prevent overcharging. 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 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 Uniso) A can be set in the charger B to be 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 unit A, and stops the oscillation of electromagnetic waves through the operation control circuit section 82, which is also built in the treatment device unit A, and turns off the LED 14.

This prevents wasteful power consumption. When charging of the rechargeable battery 18 of the treatment device unit A is started 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.

As seen in the above embodiment, since the IC circuit for controlling the charging operation is provided on the treatment unit side, only the charging indicator lamp is provided on the charger side, simplifying the structure. In addition to improving assembly efficiency and economic efficiency, the charging voltage of the rechargeable battery can be detected without being affected by the quality of contact with the charger, making detection of the charging voltage more accurate and improving the charging voltage of the rechargeable battery. charging becomes reliable.
