Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone chargers, in particular to a mobile phone charger. Background Art

[0002] A mobile phone charger is a device that charges mobile phones. It uses high-frequency power supply technology, advanced intelligent dynamic adjustment charging technology, and power electronic semiconductor devices to convert AC power with fixed voltage and frequency into DC power. The charger is mainly composed of a stable power supply (mainly a voltage-stabilized power supply, providing stable working voltage and sufficient current) plus necessary constant current, voltage limiting, time limiting, overshoot and other control circuits;

[0003] During the charging process of a mobile phone charger, when the mainboard of the mobile phone charger is contaminated with dust or the mobile phone charger is used for a long time, the mainboard of the charger is prone to short circuit, causing the charger to heat up and burn, resulting in a fire. In addition, when the user finishes charging the mobile phone, he often forgets to unplug the charger from the power socket, and the mainboard on the mobile phone charger is connected to the power supply, which will also reduce the service life of the mobile phone charger and cause the charger to catch fire. Therefore, a mobile phone charger is designed to solve the above problems. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides a mobile phone charger which can prevent the charger from overheating and burning, and prevent fire from occurring, and has high practicality.

[0005] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0006] A mobile phone charger comprises a charger shell, a plug, a data cable, a control switch, a charger mainboard, a controller and a temperature sensor, wherein a plug is provided through the right end of the charger shell, a data cable is electrically connected to the left side of the charger shell, a control switch is fixedly provided on the right side of the inner side of the charger shell, a control switch is fixedly provided on the left side of the inner side of the charger shell, a charger mainboard is fixedly provided on the left side of the inner side of the charger shell, a controller is fixedly provided on the side of the charger shell, and a temperature sensor is fixedly provided on one side of the controller.

[0007] Furthermore, the plug is electrically connected to the control switch, and the control switch is electrically connected to the charger mainboard.

[0008] Furthermore, the controller and the temperature sensor are electrically connected to the plug.

[0009] Furthermore, the controller is electrically connected to the temperature sensor and the control switch.

[0010] Furthermore, an infrared sensor is embedded in the end surface where the data cable is connected to the mobile phone.

[0011] Furthermore, the infrared sensor is electrically connected to the plug, and the infrared sensor is signal-connected to the controller.

[0012] It can be seen from the above technical solution that the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a control switch, a controller and a temperature sensor. When the temperature sensor senses that the temperature inside the charger shell is too high, it is sensed by the temperature sensor and sends a signal to the controller. The controller controls the control switch to close, disconnects the power supply between the plug and the charger mainboard, and achieves the effect of powering off the charger mainboard, preventing the charger from catching fire due to a short circuit in the charger mainboard, and ensuring safety in use.

[0014] 2. The utility model is provided with an infrared sensor. When the mobile phone is unplugged from the data cable and not charged, the infrared sensor cannot sense the mobile phone. At this time, the infrared sensor sends a signal to the controller, and the controller controls the control switch to turn off, disconnecting the power supply between the plug and the charger motherboard, thereby achieving the effect of cutting off the power to the charger motherboard, further preventing the charger from catching fire due to a short circuit in the charger motherboard, and ensuring safety in use.

[0022] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0023] See also Figure 1-4 A mobile phone charger comprises a charger shell 1, a plug 2, a data line 3, a control switch 4, a charger mainboard 5, a controller 6 and a temperature sensor 7. The right end of the charger shell 1 is penetrated by the plug 2, the left side of the charger shell 1 is electrically connected to the data line 3, the control switch 4 is fixedly arranged on the right side of the inner side of the charger shell 1, the control switch 4 is fixedly arranged on the left side of the inner side of the charger shell 1, the charger mainboard 5 is fixedly arranged on the left side of the inner side of the charger shell 1, the controller 6 is fixedly arranged on the side of the charger shell 1, and the temperature sensor 7 is fixedly arranged on one side of the controller 6.

[0024] During actual use, by providing a control switch 4, a controller 6 and a temperature sensor 7, when the temperature sensor 7 senses that the temperature inside the charger housing 1 is too high, it is sensed by the temperature sensor 7 and sends a signal to the controller 6. The controller 6 controls the control switch 4 to close, disconnects the power supply between the plug 2 and the charger main board 5, and achieves the effect of cutting off the power to the charger main board 5, preventing the charger from catching fire due to a short circuit in the charger main board 5, thereby ensuring safety in use.

[0025] In this embodiment, the plug 2 is electrically connected to the control switch 4, and the control switch 4 is electrically connected to the charger mainboard 5. By connecting the control switch 4 between the plug 2 and the charger mainboard 5, the control switch 4 can disconnect the circuit between the plug 2 and the charger mainboard 5, thereby achieving the effect of cutting off the power to the charger mainboard 5.

[0026] In this embodiment, the controller 6 and the temperature sensor 7 are electrically connected to the plug 2, and the plug 2 directly provides power to the controller 6 and the temperature sensor 7 to ensure that the controller 6 and the temperature sensor 7 work normally when the charger is powered on.

[0027] In this embodiment, the controller 6 is electrically connected to the temperature sensor 7 and the control switch 4 . The temperature sensed by the temperature sensor 7 can be transmitted to the controller 6 in real time, and the controller 6 can open and close the control switch 4 .

[0028] In this embodiment, an infrared sensor 8 is embedded in the end surface of the data cable 3 that is connected to the mobile phone.

[0029] In this embodiment, the infrared sensor 8 is electrically connected to the plug 2 , and the infrared sensor 8 is signal-connected to the controller 6 , and the plug 2 can provide power to the infrared sensor 8 .

[0030] In some implementations, an infrared sensor 8 is provided. When the mobile phone is unplugged from the data cable 3 and is not charged, the infrared sensor 8 cannot sense the mobile phone. At this time, the infrared sensor 8 sends a signal to the controller 6. The controller 6 controls the control switch 4 to turn off, disconnecting the power supply between the plug 2 and the charger mainboard 5, thereby achieving the effect of cutting off the power to the charger mainboard 5, further preventing the charger from catching fire due to a short circuit in the charger mainboard 5, and ensuring safety in use.

[0031] In some implementations, by providing an infrared sensor 8, it is possible to detect people moving around the charger housing 1. When there are people moving around the charger housing 1, the infrared sensor 8 sends a signal to the controller 6, and the controller 6 controls the control switch 4 to turn on, and then turns on the power between the plug 2 and the charger mainboard 5.

[0032] When there is no human activity around the charger housing 1, the infrared sensor 8 also sends a signal to the controller 6, and the controller 6 controls the control switch 4 to be closed, disconnecting the power supply between the plug 2 and the charger mainboard 5, thereby further improving the safety of the device.

[0033] In this embodiment, a signal transmitter (not shown in the figure) and a communication terminal (not shown in the figure) are also included. The signal transmitter is fixedly arranged on the left side of the outside of the charger housing 1, the signal transmitter is electrically connected to the controller 6, and the signal transmitter is signal-connected to the communication terminal (such as a mobile phone, a computer, etc.).

[0034] By setting up a signal transmitter, the controller 6 controls the control switch 4 to be closed, and when the power supply between the plug 2 and the charger mainboard 5 is disconnected, the controller 6 controls the signal transmitter to transmit the signal to the communication terminal in time, and then the operator can deal with it in time.
