Abstract

A smoke detector capable of multi-mode charging and a firefighting system including the smoke detector. The smoke detector includes a housing, a working module arranged in the housing and configured for detecting smoke and making a response, and a battery module configured for providing electrical energy to the working module, and further includes: a wireless charging module electrically connected to the battery module, and configured for being in wireless connection with an external wireless charging device to receive electrical energy therefrom and provide the received electrical energy to the battery module; and a light energy charging module electrically connected to the battery module, and configured for collecting light energy in a surrounding environment and converting it into electrical energy which is then provided to the battery module.

Claims (13)

1. A smoke detector capable of multi-mode charging, comprising a housing, a working module arranged in the housing and configured for detecting smoke and making a response, and a battery module configured for providing electrical energy to the working module, wherein the smoke detector further comprises:

a wireless charging module electrically connected to the battery module, and configured for being in wireless connection with an external wireless charging device to receive electrical energy therefrom and provide the received electrical energy to the battery module; and

a light energy charging module electrically connected to the battery module, and configured for collecting light energy in a surrounding environment and converting it into electrical energy which is then provided to the battery module;

wherein the smoke detector further comprises a support member configured for providing support to the external wireless charging device during the wireless charging;

wherein the support member is configured as a telescopic structure and has at least a first state in which the support member is at least partially accommodated inside the housing, and a second state in which the support member is at least partially placed outside the housing to provide a support position for the external wireless charging device.

2. The smoke detector capable of multi-mode charging according to claim 1 , wherein the wireless charging module comprises at least one electromagnetic induction coil and a wireless charging control circuit electrically connected to the electromagnetic induction coil.

3. The smoke detector capable of multi-mode charging according to claim 2 , wherein there are two or more electromagnetic induction coils arranged respectively at different positions inside the housing.

4. The smoke detector capable of multi-mode charging according to claim 1 , wherein the wireless charging module and/or the light energy charging module are arranged inside the housing, or are at least partially arranged outside the housing.

5. The smoke detector capable of multi-mode charging according to claim 4 , wherein the light energy charging module comprises at least one photoelectric sheet arranged on an outer wall of the housing or near a smoke inlet of the housing.

6. The smoke detector capable of multi-mode charging according to claim 1 , wherein the smoke detector further comprises a support member configured for providing support to the external wireless charging device during the wireless charging.

7. The smoke detector capable of multi-mode charging according to claim 1 , wherein the smoke detector has a charging interface configured for being connected to an external power source through a cable to charge the battery module.

8. The smoke detector capable of multi-mode charging according to claim 1 , wherein the external wireless charging device comprises a mobile communication device with a wireless charging function.

9. A firefighting system, including one or more smoke detectors capable of multi-mode charging according to claim 1 .
