Description

Description: TECHNICAL FIELD The present invention relates to a rechargeable blood circulation promoting device set.

[Background technology]

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

Therefore, a blood circulation promoting device for that purpose has been developed. This blood circulation promoting device is used by being directly attached to a site where blood circulation retention occurs such as a dust. As such a device, recently, in a case attached to the affected area, a high frequency generating circuit,
It has been proposed that one unit is configured by incorporating a rechargeable battery that drives this and an antenna that forms an electromagnetic field by the function of the circuit. Since this device is unitized, it has advantages such as very convenient handling.

By the way, in the above-mentioned conventional device, since the battery is of the type that is exchanged, it is not only troublesome to exchange the battery, but also because the device is a piece type, it may be lost. Therefore, a charger has been proposed that accommodates the blood circulation promoting device and also performs charging. In this device, one blood circulation promoting device is attached to and detached from one charger, and the blood circulation promoting device automatically starts discharging when removed from the stored state. Therefore, when it is desired to use a large number of blood circulation promoting devices, one previously charged blood circulation promoting device has already started discharging when one blood circulation promoting device is charged and the next blood circulation promoting device is charged. As a result, at the time when all the blood circulation promoting devices have been charged, these blood circulation promoting devices are discharged at each time from the time when they are removed, and each blood circulation promoting device when these blood circulation promoting devices are attached to the body. This is inconvenient because the discharge time of the accelerator is uneven. Therefore, for example, one large-capacity charger may be prepared so that a large number of blood circulation promoting devices can be charged at the same time by this one, but this is uneconomical and charging is difficult. Save space when storing and using the container. If each blood circulation promoting device is equipped with a manual switch that turns the power on and off, the above irregularities will be eliminated, but this will increase the cost of the blood circulation promoting device, and at the same time, the shape will increase to a large extent, and a complicated waterproof structure will be provided. Must be taken.

[Object of the Invention]

In view of the circumstances, the present invention provides the above-mentioned economical efficiency,

It is supposed to do. The treatment device unit A includes a disk-shaped unit case 1 made of a plastic material. This unit case 1 is composed of a combination of a plate-shaped case body 2 on the side to be worn on the body and a case cover 3 located outside thereof. The case main body 2 has a circular opening at the center thereof as a charging opening 4 penetrating in the plate thickness direction, and a large number of ventilation grooves 5 are radially formed on the mounting surface (outer surface) thereof.
A fitting groove 6 into which the outer peripheral edge portion 7 of the case cover 3 is fitted is formed on the outer peripheral portion of the surface (inner side surface) of the case body 2 corresponding to the case cover 3 side, and the fitting groove 6 is formed. The portion inside the inner protrusion 6a is a recess 8 for inserting the substrate.
It has been. The case cover 3 has an overall thin spherical shape in which the central portion from the center to about 1/2 of the radius is high and the outer peripheral portion following the case is gently lowered. The outer peripheral edge portion 7 of the case cover 3 is fitted in the fitting groove 6 of the case body 2, and in order to enhance waterproofness, the entire circumferences of the both 6 and 7 are airtightly joined by an ultrasonic welder. . In this case, the outermost peripheral edge portion of the case body 2 is provided with a cylindrical engagement protrusion 9 that protrudes very low upward, and the engagement protrusion 9 is located on the outer periphery of the case cover 3. . A circular printed circuit board 10 is fitted in the board fitting recess 8, and the outer peripheral portion is sandwiched between the outer peripheral portions of the case body 2 and the case cover 3. An O-ring 12 made of silicon rubber or the like is provided in a ring groove 11 formed inside the outer peripheral edge portion 7 of the case cover 3.
Is inserted and the O-ring 12 is pressed against the outer peripheral portion of the printed circuit board 10, whereby the case cover 3 and the printed circuit board 10 are airtight. This airtight structure part is the unit case 1 together with the welder joint part.
The waterproof property of is improved.

The printed circuit board 10 has an IC circuit pattern forming a high frequency generation circuit for generating an electromagnetic field formed on the outer peripheral portion of the surface thereof on the case cover 3 side by a printing technique, and the printed surface. , IC circuit parts 13 or LE
D14 is deployed. Inside the IC circuit pattern, a rechargeable battery 18 for driving the high frequency generation circuit is provided, and first and second connection fittings 15, 16 electrically connected to the rechargeable battery 18 are also provided. ing. The LED 14 is designed to repeatedly blink when the treatment device unit A is generating a high-frequency electromagnetic field, and to turn off in other cases, so that the state can be discriminated from the outside. A see-through operation confirmation window 17 is provided at a portion of the case cover 3 corresponding to the LED 14. This operation confirmation window 17 is used when an opaque printing process is performed on the surface of the case cover 3 formed of a transparent resin material.
It is formed so that only the portions corresponding to 17 are left transparent. On the other hand, the unit-side first charging terminal 20 and the unit-side second charging terminal 21 are arranged in the central portion of the surface of the printed circuit board 10 on the case body 2 side (the side where the body is attached to an adhered portion such as the body). Antennas are arranged on the outer peripheral portion and are electrically connected to the IC circuit patterns through through holes. These charging terminals 20 and 21 and the antenna are all formed by a printing technique.
The unit-side first charging terminal 20 is located in the center of the printed circuit board 10, and the unit-side second charging terminal 21 is located concentrically on the outer periphery thereof. The unit-side first charging terminal 20 has a perfect circular shape, but the unit-side second charging terminal 21
Has a C-shape extending approximately 270 degrees in the circumferential direction. As described above, since the unit-side second charging terminal 21 is formed in the C-shape instead of the perfect ring shape, the high frequency eddy current loss generated by the antenna does not occur. The unit-side first charging terminal 20 and the unit-side second charging terminal 21 are configured so as not to be broken by a short circuit even if the unit case is attached to the body for bathing or sweat adheres. The antenna is formed in a spiral shape so as to surround both charging terminals 20 and 21 provided in the central portion of the printed board 10 from the outer circumference.

A protective sheet 25 for waterproof insulation is provided on the surface of the printed circuit board 10 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 thereof, and an arc-shaped second through hole 27 similar to the unit side first charging terminal 20 and slightly smaller than the circular second through hole 27 on the outer periphery thereof. I have it. The protective sheet 25 has double-sided adhesiveness, the first through hole 26 is concentrically located in the center of the circular unit-side first charging terminal 20, and the second through hole 27 is the unit-side second charging terminal. It is located in the center of the width of 21, and one side is the case body 2,
The other surface is bonded onto the printed circuit board 10. Protective sheet
The surface of the case body 2 side of 25 is made of the case body 2 by an adhesive.
It is adhered to the surface of the board fitting recess 8 of. In this way, all the through holes are closed by the protective sheet 25, the waterproof between the printed circuit board 10 and the case body 2 is ensured, and sweat and water do not enter the case, so that germs are generated. It is also prevented. First through hole 26 of protective sheet 25
The second through hole 27 is the first unit side of the printed circuit board 10.
Since the protective sheet 25 is adhered not to the stepped portion of each copper foil pattern forming the charging terminal 20 and the unit-side second charging terminal 21 but to the inner flat surface of the copper foil pattern, the protective sheet 25 rises or peels off. There is no such thing, and a more reliable waterproofing effect is exhibited.

On the surface of the case body 2 that is attached to the skin surface 30,
A mounting member 31 that is breathable like a foamed polyurethane material and that can be deformed according to the shape of the skin surface 30 to prevent mechanical rash is detachably and replaceably attached.
The mounting member 31 is a thin ring having a circular vent 32 at the center thereof. Adhesives 35, 35 are applied to both sides of the mounting member 31, one of which is the case body 2.
Is affixed to the surface of the ventilation groove 5 side, and the other is affixed to the adhered site such as the skin surface 30. Each adhesive 35 is provided with a vent hole 34. Since the vent hole 32 in the center of the mounting member 31 is formed larger than the charging opening portion 4 of the case body 2, the adhesive 35 is applied to both charging terminals 20, 21.
Since it is far away from these terminals, it is hard to adhere to these terminals. This prevents contact failure between the charging terminals 20 and 21 due to adhesion of the adhesive. The mounting member 31
Is adhered to the skin surface 30 and the like, but since the vent hole 32 is formed in the surface, steam and body heat from sweat once enter the vent hole 32, and the vent groove 5 and the wearing It is discharged to the outside in the radial direction of the unit case 1 through the member 31. Further, these vapors or the like are discharged in the outer diameter direction through the ventilation hole 34 and the ventilation hole of the mounting member 31 itself, or are discharged from the mounting member 31 to the outside of the unit case through the ventilation groove 5. .

In this way, steam and body heat are effectively eliminated through many routes, thus more effectively preventing rashes. The mounting member 31 has a relatively large vent 32 at the center thereof.

The treatment device unit A includes a main charger B described below.
And the sub-charger C are respectively set and charged.

The charger main body 41 of the main charger B is configured by vertically aligning the lower case 51 and the upper case 52 and fixing them to each other with screws 53. The lower case 51 has a battery cover 54
Since it is detachably equipped, if you remove it, the upper case 52
The dry battery (charging power source) 56 housed in the battery receiver 55 on the side is removable and replaceable.

The upper case 52 has a flat surface that is slightly higher on one side, but has a concave shape on the other side. The central portion of the recessed portion is cylindrically recessed, and the recessed portion serves as a charging case fitting recess 57. The charging case fitting recess 57 includes a cylindrical peripheral wall 57a and a circular bottom wall 57b, and a button setting port 58 is provided on one side of the peripheral wall 57a.
Further, spring windows 59 are arranged on the other side so as to face each other.

In the button setting port 58, a push button 60 having an operation concave portion 60a on the upper portion and a guide shaft 60b protruding on the lower portion is fitted, and the push button 60 is attached to each wall of the lower case 51 and the upper case 52. Guided by the section, it is movable up and down. This push button 60
The return spring 61 constantly urges it upward, and is normally received and locked by the upper case 52 side.
The end surface of the push button 60 on the charging case fitting recess 57 side is formed to be a curved surface continuous with the cylindrical surface of the charging case fitting recess 57, but only the upper edge portion thereof is for charging. An arc-shaped first stopper 62 is formed so as to slightly project to the case fitting recess 57 side. The first stopper 62 forms a first engagement groove 64 with which the engagement projection 9 (see also FIG. 1 and FIG. 2) of the unit case 1 fits with the outer peripheral end of the bottom wall 57b. are doing. Above the first stopper 62,
A first guide surface 63 which is a part of the inverted conical surface (tapered surface) is formed.

On the other hand, the central portion of the engagement push spring 66 faces the spring window 59 so as to advance and retract in the engagement direction of the charging case fitting recess 57. The engagement push spring 66 is formed as a strip-shaped piece made of a plastic material, and fulcrums 67 at both ends thereof are supported by the upper case 52 as shown in FIG. It can be elastically deformed. A second engaging groove 68 into which the engaging protrusion 9 of the unit case 1 is fitted is formed in a central portion of the second engaging groove 68, and a second engaging groove 68 is formed above the second engaging groove 68.
The stopper 69 is formed to project. This second stopper 69
Like the first stopper 62, normally, it slightly projects into the charging case fitting recess 57. The second stopper 69 is formed in an arc shape when viewed from above, and a second guide surface 70 which is a part of an inverted conical surface is formed above the second stopper 69.

An oblong protrusion 73 is formed on the bottom wall 57b of the charging case fitting recess 57, and three spring through-holes 74, 75, 75 are formed in the portion having the protrusion 73 so as to vertically pass therethrough. Has been formed. The spring through hole 74 in the center is formed in the charging case fitting recess 57.
The other spring through holes 75, 75, which are located at the center of, are arranged on both sides thereof with a 180-degree offset from each other. A contact terminal 76 is inserted into the central spring through hole 74, and contact terminals 77 and 77 are inserted into the spring through holes 75 and 75 on both sides so as to be vertically movable, and project upward. These contact terminals 76, 77, 77 are electrically connected to a printed circuit board 78 mounted on the bottom of the upper case 52, respectively, and contact the charging terminals 20, 21 when the unit case 1 is mounted, and At this time,
It also functions to push the unit case 1 upward. On the top surface of the upper case 52, a charging indicator lamp 79
Is provided.

The unit case 1 is attached to and detached from the main charger B as follows. That is, when the unit case 1 is pushed into the charging case fitting recess 57 with both charging terminals 20 and 21 facing downward, one end of the unit case 1 is engaged with the second guide surface 70 to engage the push spring. Elastically deform 66 to push it away. As a result, the second stopper 69, which previously had the gap L in the back, is pushed away and the back wall
The engaging projection 9 of the unit case 1 can pass through between the first stopper 62 and the second stopper 69 by retracting to the 71 side. The engagement protrusion 9 of the unit case 1 is fitted into the first engagement groove 64 and the second engagement groove 68 through the space therebetween, and is engaged with these. This engagement is due to the elastic return action of the engagement push spring 66 moving to the recess 57 side. In this manner, the unit case 1 is set in the charging case fitting recess 57, and at the same time, the unit-side first charging terminal 20 exposed on the lower surface of the unit case 1 contacts the contact terminal 76 of the charger, And the unit side second charging terminal
21 contacts any one of the contact terminals 77, 77 of the charger to complete the charging state.

This charging posture is also a storage posture of the unit case 1. The operation to reach this state may be performed by holding the unit case 1 with one hand and pushing it into the charging case fitting recess 57. In this state, the unit-side first charging terminal 20 and the contact terminal 76 are both on the center, so that the unit case 1 is always surely aligned and electrically connected regardless of the orientation of the unit case 1. On the other hand, regarding the unit-side second charging terminal 21 and the contact terminal 77, the unit-side second charging terminal 21 may have a C-shape depending on the orientation of the unit case 1 as long as there is only one contact terminal 77. In some cases, the unit-side second charging terminal 21 does not match the second guide surface 77. However, since the pair of contact terminals 77 are arranged 180 degrees apart from each other, and the unit-side second charging terminal 21 is provided in a C-shape with an angle larger than that,
Regardless of the orientation of the unit case 1, at least one of the contact terminals 77 is connected to the unit-side second charging terminal 21.
Will come into contact. As a result, electrical continuity between the unit side second charging terminal 21 and the contact terminal 77 is always ensured. Further, in the charged state, the unit case 1 is not simply engaged with the first engagement groove 64 and the second engagement groove 68, but is always in the second state by the elastic force of the engagement bush spring 66.
It is designed to be pushed to the side of the engaging groove 68.
The engaged state is surely maintained and the charging is surely performed.

To remove the unit case 1 from the charger main body 41,
All you have to do is press push button 60. That is, when the push button 60 is pressed, the first engaging groove 64 is lowered and the engaging protrusion 9 of the unit case 1 is engaged with the engaging bush spring 66 like a cam.
Push back in the direction of. As a result, the engagement push spring 66 retracts, so that the first engagement groove 64 is lowered and the engagement projection 9 is lowered.
Get over. At this time, the elastic force of the contact terminals 76, 77 acts as a pushing-up force on the lower surface of the unit case 1, so that the unit case 1 comes out of the push button 60 side and rides on the first guide surface 63. . When you release the push button 60 from that state, the push button 60
Is returned by lifting the one end of the unit case 1 by the returning force of the return spring 61. The unit case 1 thus configured can be easily removed by touching the engaging projection 9 with a finger or a nail and lifting it. All the operations in the meantime can be performed easily and quickly with one hand, and after that, by attaching the attachment member 31 to the back surface of the unit case 1, it can be attached to the body.

Each control of overcharge prevention to the rechargeable battery 18 is performed based on the voltage detection between 20 and 21. As shown in the operation flow of those circuit configurations in FIG. 14, while the rechargeable battery 18 has the power supply voltage, electromagnetic waves are radiated from the antenna through the oscillation circuit section 83 and the user is in the operating state. LED14 is lit by the LED lighting circuit to notify the. This is confirmed through the operation confirmation window of the unit case 1. If it is recognized that the electromagnetic wave oscillation is stopped by turning off the LED 14, the treatment device unit A can be set in the charger B and charging can be performed. When the LED 14 is turned on and the electromagnetic wave oscillates and the battery B is set in the charger B, the charging voltage detection circuit 81 is built in the treatment device unit A side. Therefore, this circuit 81 is connected between the charging terminals 20 and 21. It detects that there is a voltage input from the main charger B by voltage detection, stops the oscillation of electromagnetic waves through the operation control circuit unit 82 also incorporated in the treatment device unit A, and LED1
Turn off 4 This prevents wasteful power consumption. When charging is started from the dry battery (charging power source) 56 to the rechargeable battery 18 of the treatment device unit A through the contact terminals and the charging terminals 20 and 21, the operation control circuit section 82 lights the charging indicator lamp 79 of the charger B. To inform the user that the battery is charging. When it detects that the voltage of the rechargeable battery 18 is equal to or higher than the specified value or that the charging time has exceeded a predetermined time, it stops charging the rechargeable battery 18 to prevent overcharging and charges the main charger B. The middle display lamp 79 is also turned off to inform the user that the charging is completed.

By the way, on the printed circuit board 78 of the main charger A, the first and second main connection springs 9 are provided at the end positions on the opposite side of the dry battery 56.
2,93 are projected. Each of these springs 92 and 93 is electrically connected to a circuit on the printed circuit board 78.

The insertion hole 94 is provided so as to penetrate therethrough.

The sub charger C is arranged so as to be in contact with the main charger B so as to be electrically conductive. The charger main body 91 of the sub charger C has a small case in which the battery housing portion of the main charger B is omitted, and the treatment device unit A is set, charged and removed. The same parts such as the charging indicator lamp are attached with the same symbols as those attached to the main charger B. The sub charger C has an outlet 95 on one side wall and a sub insertion hole 96 on the other side wall. From the outlet 95, a first terminal pin 97 and a second terminal pin 98, which are attached to the printed circuit board 78 of the sub-charger C and project horizontally, are taken out. These pins 97, 98 are arranged inside and outside via an insulating tube 99, and the insertion hole 94 of the main charger B is also provided.
When the first terminal pin 97 is inserted into the first terminal pin 97,
The second terminal pins 98 are electrically connected to the main connection springs 92 and the second main connection springs 93, respectively. The first and second terminal pins of another sub-charger are inserted into the sub-insertion hole 96 of the sub-charger C, and the first and second sub-connections are arranged inside the insertion hole 96. The springs 100 and 101 are electrically connected to each other.

In this way, it is possible to connect the sub chargers to the main charger one after another, so multiple treatment device units can be set and the treatment device units start discharging when they are removed. Even in such a case, all the units can be taken out and mounted on the body at the same time, so that the discharge time is not shifted and all the units are even, and an equal amount of electromagnetic waves act on any affected part. Moreover, since it is not necessary to provide a manual switch on the treatment device unit in order to make the discharge time uniform, it is not necessary to increase the size of the unit or to provide a complicated waterproof structure.

Although the sub-charger is connected to the main charger in series, the sub-charger may be connected radially using the main charger as a terminal. In the above-described embodiment, the insertion hole and the connection spring are arranged on the main charger side, and the terminal pin is arranged on the sub charger side.However, the terminal pin is arranged on the main charger side and the insertion hole is formed on the sub charger side. A connection spring may be arranged.
