になる。(Prior Art) Chargers have been known that charge a secondary battery of a small electric device, such as a Ni-Cd battery, by lowering the voltage from a commercial power supply using a transformer or an inverter. Some of this type of charger performs quick charging in about one hour, and this charger requires a large current to flow through the secondary battery, and is small in size and uses an inverter with low power loss. Those that use circuits are common. However, in order to perform ultra-quick charging with a roughly shortened charging time, it is necessary to further increase the charging N current, and therefore, even if an inverter circuit is used, the size becomes large and the power loss increases. In addition, if the secondary battery is overcharged with a large current flowing through it, the secondary battery may deteriorate and its reliability may decrease, or the secondary battery may explode due to increased internal pressure due to gas generation within the secondary battery. Sometimes. For this reason, a charging control circuit is required to cut off the charging Ti current when it is fully charged and charge is completed, or to reduce the charging current to a minute current that will not cause the secondary battery to explode.As the charging current for quick charging increases, Operation accuracy of the charging control circuit is required.
また、別の簡易充電器として乾電池を用いて２次電池に
充電するものがある。ところが、この充電器は充電ごと
に乾電池を交換する必要があり、また、上記乾電池は内
部抵抗が大きいので、ある程度の急速充電はできるが、
充電時間は余り短くならない。Further, there is another simple charger that charges a secondary battery using a dry battery. However, this charger requires replacing the batteries each time it is charged, and the batteries mentioned above have a large internal resistance, so although they can charge quickly to a certain extent,
Charging time is not too short.

第１図に示すように、電池の数が増えるとガス扱きパイ
プもそれに対応して増え、その結果、コネクタ部が大き
くなり、コネクタの着脱に大きな力が必要となる。On the other hand, electric shavers that can be washed with water have a sub-rechargeable battery installed inside the device, and when the main rechargeable battery (secondary battery) runs out of battery capacity, this sub-rechargeable battery replaces the battery capacity that has run out. By installing this sub-rechargeable battery, you can shave several times more. However, this rechargeable battery requires a gas release pipe to be installed.
As shown in FIG. 1, as the number of batteries increases, the number of gas handling pipes also increases correspondingly, resulting in a larger connector section and the need for greater force to attach and detach the connector.
ここで、電気かみそりの構成について第１図を用いて説

Reference numeral 4 indicates a motor that drives the blade 2, and 4 indicates a main rechargeable battery.A sub-rechargeable battery (not shown) is connected in parallel to the main rechargeable battery 4. 5 is a gas vent pipe that also serves as a positive terminal bottle, 6
is a negative terminal pin, 7 is another 1-N battery, and this other main rechargeable battery 7 is connected in parallel with another sub-rechargeable battery (not shown). 8 is a gas vent pipe for the main rechargeable battery 7, 9
is a connector that connects a charging adapter (not shown) and the electric shaver.

めて困難である。As shown in Figure 1, recently I have been trying to increase the number of times I shave. The number of electric razors that use two batteries is increasing, but in this case, two sub-rechargeable batteries are also required, and as a result, four gas vent pipes are required for these rechargeable batteries. It is extremely difficult to configure a real gas handling pipe to lead to the outside of an electric shaver.
このため、主充電電池（例えば２本）のみを電気かみそ
りに配設し、この主充電電池を超急速充電することで、
充電時間を短縮する充電器の実現が望まれていた。Therefore, by installing only the main rechargeable batteries (for example, two batteries) in the electric shaver and charging these main rechargeable batteries ultra-quickly,
It has been desired to create a charger that shortens charging time.

However, K1- (1/discharge efficiency of the first rechargeable battery 12)
By configuring the relationship of x charging efficiency of the second rechargeable battery 16 x efficiency of the charging circuit 11, it is possible to fully charge the second rechargeable battery 16 with the first rechargeable battery 12 in a short time. , the battery capacity C1 of the first rechargeable battery 12 is exhausted before the second rechargeable battery 16 is overcharged, so that the second rechargeable battery 16 is not overcharged and it is necessary to use an overcharge control circuit or the like.

6 is connected to a commercial power source, the second rechargeable battery 16 will continue to be charged from the charging circuit 11 even after charging from the first rechargeable battery 12 is completed! The second rechargeable battery 16 can be configured to trickle charge with the current. Therefore, with the charging circuit 11 having the above configuration, it is possible to charge both the first rechargeable battery 12 and the second rechargeable battery 16, and when the main body 14 is an electric shaver, the second charging circuit of the electric shaver can be charged. Once the battery 16 is charged, 7~
It can be used for 14 days, and the first rechargeable battery 12 only needs to be charged during this period, and the charging circuit 11 only needs a small output. Therefore, the charger can be supplied at low cost, and the second charging Trickle charge can be supplied to battery 16.

According to this configuration, the second rechargeable battery 1 is
When the battery capacity C2 of 6 is exhausted, the first rechargeable battery 1
2 can be rescue-charged (20 to 30 seconds), there is no need to arrange a sub-battery in the main body 14, and mechanisms such as gas handling pipes (especially when there are many rechargeable batteries) can be simplified. Furthermore, a timer circuit is provided in the charging adapter 10 to control the charging time for the second rechargeable RN battery 16 (for example, the time required to charge the battery to a capacity that can be used to drive the functional circuit 15 several times). It can also be configured to have functions.

ることができる。(Effects of the Invention) As described above, according to the present invention, it is possible to directly charge the second rechargeable battery in the 1m electric appliance from the first rechargeable battery in the charging adapter, thereby eliminating the need for a conventional transformer. The shape of the charging adapter can be made smaller compared to chargers that use an inverter or a high-output inverter, and unlike high-output inverters that generate high frequency and large current, which can cause radio interference, this type of charger eliminates the problem of radio interference. Moreover, there is no need to use a charging control circuit, and ultra-quick charging is possible despite the small size.
