Description

Electronic device capable of preventing battery leakage

The invention relates to an electronic device, in particular to an electronic device capable of preventing battery leakage.

If the existing battery-powered electronic devices are used frequently, there will be no problem of battery leakage. For example, if the battery-powered electronic device is a remote control of a TV, the buttons are usually pressed by the user every day. There will be no battery leakage.

On the contrary, if the remote control of the home appliance is not often used, for example, in winter, the remote control of the air conditioner may not be pressed by the user for several months, so the battery in the remote control of the air conditioner may not be used for a long time. And there is the problem of night leakage. Therefore, it is necessary to find a solution.

Therefore, the object of the present invention is to provide an electronic device capable of preventing battery leakage.

Therefore, the electronic device capable of preventing battery leakage of the present invention includes: a load; a battery, which is used to supply power to the load; and a controller, which is electrically connected to the load and the battery, and when the battery is suspended to the load When power is supplied, the controller performs a battery activation process on the battery to prevent the battery from leaking.

The effect of the present invention is that when the battery of the electronic device (such as a home appliance remote control, etc.) capable of preventing battery leakage of the present invention suspends power supply to the load, the controller automatically performs the battery activation process on the battery, so it can Prevent the battery from leaking.

Referring to FIG. 1, an embodiment of an electronic device 1 for preventing battery leakage in the present invention includes a load 11, a battery 12, and a controller 13. In this embodiment, the electronic device 1 for preventing battery leakage of the present invention may be an infrared remote controller such as a home appliance (not shown), so the load 11 may include a button unit 111 and an infrared emitting unit 112, the button The unit 111 can be operated by a user to trigger the controller 13 to control the infrared emitting unit 112 to emit an infrared remote control signal that can remotely control the home appliance. However, in other embodiments of the present invention, the electronic device 1 capable of preventing battery leakage is not limited to an infrared remote controller, but may also be another type of electronic device.

The battery 12 is mainly used to supply power to the load 11 and may be, for example, a rechargeable battery or a non-rechargeable battery.

The controller 13 is electrically connected to the load 11 and the battery 12. When the battery 12 suspends power supply to the load 11, the controller 13 performs a battery activation process on the battery 12 to prevent the battery 12 from leaking. In this embodiment, the so-called battery 12 suspends power supply to the load 11 means that the user does not press the button of the button unit 111 to trigger the controller 13 to control the infrared emitting unit 112 to emit infrared remote control signals for remotely controlling household appliances. The battery 12 temporarily does not supply power to the key unit 111 and the infrared emitting unit 112.

Referring to FIGS. 1 and 2, the battery activation process performed by the controller 13 will be described below by taking the electronic device 1 capable of preventing battery leakage as an infrared remote controller as an example. As shown in step 20, the user presses a key of the button unit 111 to trigger the infrared emitting unit 112 to emit an infrared remote control signal of a remote control household appliance, whether the button unit 111 is pressed or the infrared emitting unit 112 emits infrared remote control signals, all must consume the power of the battery 12, therefore, if the user presses the buttons of the button unit 111 frequently, for example, in summer, when pressing the buttons of the button unit 111 of the remote control of the air conditioner, the battery 12 It will be in the power supply state, so the battery 12 will not leak due to long-term non-use. However, in winter, the keys of the key unit 111 of the remote controller of the air conditioner may not be pressed by the user for several months, so the battery 12 may have a problem of night leakage due to long-term non-use. In this embodiment, in order to prevent the battery 12 of the electronic device 1 such as a remote controller from leaking, when the key unit 111 is pressed and the infrared emitting unit 112 emits an infrared remote control signal, the controller 13 is triggered to start battery activation. Process, as shown in step 21.

Therefore, as long as the user no longer presses the key unit 111 (as shown in step 28), the controller 13 will always perform the battery activation process as shown in steps 22 to 27.

As shown in step 22, during a first power-off period of the battery activation process, since the user does not press the button unit 111, the battery 12 does not supply power to the button unit 111 and the infrared emitting unit 112. In this embodiment, the first power-off period may be, for example, 1 to 2 days.

Then, after the timing period of the first power suspension period, as shown in step 23, the controller 13 counts a first power supply period. During the first power supply period, the controller 13 controls the infrared emitting unit 112 to emit an infrared signal of a household appliance that cannot be remotely controlled, so that the battery 12 consumes power and activates the battery 12, thereby preventing the battery 12 from leaking. In this embodiment, the first power supply period may be, for example, 1 to 3 seconds. That is to say, in this embodiment, the controller 13 will automatically control the battery 12 to consume power up to the time when the first power-off period (such as 1 to 2 days) after the button unit 111 is pressed expires During the first power supply, the battery 12 is prevented from leaking.

Then, when the user has not pressed the button unit 111 again, as shown in step 24, the controller 13 immediately counts a second power-off period. During the second power-off period, since the user does not press the button unit 111, the battery 12 does not supply power to the button unit 111 and the infrared emitting unit 112. In this embodiment, the second power-off period may be, for example, 1 to 2 days.

Then, after the timing period of the second power suspension period, as shown in step 25, the controller 13 counts a second power supply period. During the second power supply period, the controller 13 controls the infrared emitting unit 112 to emit an infrared signal of a non-remote control household appliance, so that the battery 12 consumes power and activates the battery 12, thus preventing the battery 12 from leaking. In this embodiment, the second power supply period may be, for example, 1 to 3 seconds. That is to say, in this embodiment, the controller 13 will automatically control the battery 12 to consume power for the second power supply period when the second power suspension period (such as 1 to 2 days) expires to avoid the battery 12 Leakage.

Similarly, if the button unit 111 has not been pressed again, the controller 13 will continue to sequentially execute the third power-off period (such as 1 to 2 days) and the third power-supply period (1 to 3) of the battery activation process. Seconds), ..., the nth power supply suspension period (eg 1 to 2 days), the nth power supply period (1 to 3 seconds) until the user presses the key unit 111 again as shown in step 28.

As shown in step 28, when the user presses the key unit 111 again, the controller 13 will end the battery activation process.

Since the key unit 111 is pressed again, it will trigger the controller 13 to control the infrared emitting unit 112 to emit the infrared remote control signal of the remote control household appliance again. Then, as shown in step 29, the controller 13 retimes and starts another battery activation process, that is, steps 22 to 27 will be performed again until the user presses the key unit 111 again to end the other battery activation process .

In summary, when the battery 12 of the electronic device 1 (such as a home appliance remote control, etc.) capable of preventing battery leakage of the present invention suspends power supply to the load, the controller 13 performs a battery activation process (at least including The first power-supply suspension period and the first power-supply period immediately after the first power-supply suspension period) to prevent the battery from leaking, so the purpose of the invention can indeed be achieved.

However, the above are only examples of the present invention, and the scope of implementation of the present invention cannot be limited by this, any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as Within the scope of the invention patent.
