Description

TECHNICAL FIELD The present invention relates to a 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 plurality of blood circulation promoting devices, when one blood circulation promoting device is charged and then the next blood circulation promoting device is charged, the previously charged blood circulation promoting device has already started discharging. Therefore, when the charging of a large number of blood circulation promoting devices is completed, the already charged blood circulation promoting devices are
It means that each time it is discharged from the time it is removed. As a result, when these blood circulation promoting devices are worn on the body, the discharge time of each blood circulation promoting device becomes uneven, which is inconvenient. 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.

As such, it exerts a more reliable waterproofing effect.

The surface of the case body 2 that is to be attached to the skin surface is a removable attachment member that is breathable like a foamed polyurethane material and that can deform according to the shape of the skin surface to prevent mechanical irritation. Can be freely attached.

The circuit configurations of the treatment unit A and the charger B are as shown in FIG. That is, in the treatment device unit A, the charging voltage detection circuit 81 and the operation control circuit unit 82 are integrated into the IC.
It consists of. The charging voltage detection circuit 81 and the operation control circuit section 82 oscillate and stop the electromagnetic waves of the treatment device unit A, turn on and off the LED 14, and in addition, the charger when the treatment device unit A is set in the charger B. Turning on and off the charging indicator lamp 79 of B, charging terminals 20, 21
Each control of the overcharge prevention to the rechargeable battery 18 is performed based on the voltage detection between them. As shown in the operation flow of those circuit configurations in FIG. 6, 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 LED 14 is turned on by the LED lighting circuit in order to inform the user that it is in the operating state. 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. If the charging voltage detection circuit 81 is built in the treatment device unit A side when it is set in the charger B when the LED 14 lights up and the electromagnetic wave is oscillated, this circuit 81 is connected between the charging terminals 20 and 21. By detecting the voltage input from the charger B by the voltage detection, the oscillation of the electromagnetic wave is stopped through the operation control circuit unit 82 also incorporated in the treatment device unit A, and the LED 14 is turned off. 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 stipulated value or that the charging time has exceeded a predetermined time, it stops charging the rechargeable battery 18 to prevent overcharging, while charging the charger B. The indicator lamp 79 is also turned off to notify the user that charging is completed.

By the way, the set piece C is shown in FIG.
As shown in the figure, the treatment device unit A is detachably fitted. This set piece C is formed of a plastic material in a circular and thin saucer shape,
The case body 2 is adapted. The set piece C has a long hole-shaped recess 30 in the center thereof, and a short-circuit piece (short-circuiting circuit) 31 made of a conductive rubber material is fitted into the recess 30. The piece 31 is composed of a pedestal portion 32 that bulges upward and is elastically deformed vertically, and three columnar protrusions that integrally project from the upper surface of the pedestal portion 32. The central one of the protrusions is a first short-circuit terminal 33 that contacts the first charging terminal 20, and the two protrusions on both sides of the protrusion are second short-circuit terminals 34 that contact either of the second charging terminals 21. It is supposed to be 34.

The treatment device unit A starts oscillating when it is removed from the charger B, but when it is immediately fitted into the set piece C, the first short-circuit terminal 33 is connected to the first charging terminal 20 and the second short-circuit terminal 34, One of the 34 contacts the second charging terminal 21,
The first and second charging terminals 20 and 21 are short-circuited through the pedestal portion 32. The charging voltage detection circuit 81 checks whether the treatment device unit A is detached from the charger B and whether or not there is a voltage input from the charger, sends a notification to the operation control unit 82 that the voltage has not been input, and controls the operation. When the short circuit is determined by the unit 82
The LED 14 is turned off to stop the electromagnetic wave oscillation of the treatment device unit A. When the treatment device unit A is detached from the set piece C, it is checked whether or not the charging voltage is equal to or higher than the specified voltage. If the charging voltage is equal to or higher than the specified voltage, the LED 14 blinks and an electromagnetic wave is oscillated to enable use. LE in the following cases
Turn off D14 to stop the electromagnetic wave oscillation and notify that it should be charged.

As described above, the treatment device unit is of a type that does not include a switch, and when the unit is set in the set piece, the oscillation for electromagnetic field generation is configured to stop. If you set the charged treatment unit in each set piece like this, all the treatment unit units will remain charged, and you can remove these many treatment units from the set piece at the same time. When used, all the treatment device units start oscillating for the first time, and all the treatment device units exhibit the same function in the same time zone. As a result, it is not necessary to charge multiple treatment device units at the same time, so there is no need to prepare one large charger or multiple chargers, and only the set piece is sufficient, which is economical. No space required. Since the manual switch does not have to be attached to the treatment device unit, the cost is not increased, and the shape is compact, and the complicated waterproof structure is not required. In the above embodiment, since the set piece is designed to short-circuit the charging terminals of the treatment device unit to stop the operation, the piece does not require any special electric circuit or the like other than the short-circuited parts, As a result, a small-sized piece having a simple structure can be obtained. The control circuit of the treatment device unit also performs all of the controls of oscillation, charging, and oscillation stop when the device is stored in the piece, so that the configuration of the treatment device unit can be simplified.

It should be noted that the treatment device unit A may be lost if it is set in each of the set pieces C. Therefore, these sets may be configured to be freely put in and taken out from the storage case D. The storage case D has a cylindrical shape with a bottom, and the set is stored in a laminated shape inside the storage case D. The case D has a flat surface C at its upper end.
A holding flange 40 having a letter shape is provided, and an inner opening thereof serves as an operation port 41, and an opening on one side of an upper end portion of the case D allows the set piece C of the set to pass horizontally. It is the entrance 42 that can be taken in and out. In front of the loading / unloading port 42, a slide base 43 for receiving the set from below and guiding the loading / unloading is projected in a tongue shape. In the internal space of the storage case D, a receiving seat 45, which is biased upward by a push-up spring 44, is provided so as to move up and down. As shown in FIG. 3, the set is oriented horizontally, and the set piece C is slid on the slide base 43 and inserted into the inlet / outlet port 42. If you insert the set as it is along the slide base 43,
Get on the seat 45. When the next set is inserted in the same manner, the previously inserted set is pushed down by using the upper spherical surface as a cam, and the seat 45 is also lowered by one step. In this way, as shown in FIG. 4, a large number of sets can be stored in the storage case D. When stored in this way, the treatment device unit A and the set piece C are pressed against each other without being lost, so that the contact between the charging terminal and the short-circuiting terminal is ensured and the oscillation is stopped more reliably. It can be anything. In order to take out the set, the set may be pushed out through the operation port 41 in the direction of the taking-out port 42, and each set is automatically raised by the push-up spring 44 and the receiving seat 45 to be in a state of being taken out sequentially. The set piece C may have a flat plate shape instead of the saucer shape. In the case of a flat plate shape, for example, the projecting piece of the set piece C may be fitted in the fitting hole of the treatment device unit A so that the set piece C and the treatment device unit A can be attached and detached. The rechargeable battery in the treatment device unit may be a dry battery to prevent consumption of the battery. At the peripheral portion of the set piece C, as shown in FIG. 2, an outlet 50 for the treatment device unit A may be provided.
