[0032] Please refer to Figures 1 to 4This application provides an electric tool 100, powered by a power supply device 200. In this embodiment, the electric tool 100 is an electric hammer; in other embodiments, the electric tool 100 may also be an electric drill, electric pick, electric chainsaw, etc. The power supply device 200 is a lithium battery pack.

[0033] The power tool 100 includes a tool body 50, a motor 60, a tool head mounting part 70, an infrared detection device 10, a control device 20, a prompting device 30, and a switch device 40. The tool body 50 houses the motor 60. The tool head mounting part 70 is mounted on the tool body 50 and can mount a tool head 80 driven by the motor 60. The control device 20 controls the motor 60. A power supply 200 supplies power to the motor 60, the infrared detection device 10, the control device 20, the prompting device 30, and the switch device 40. The infrared detection device 10 receives infrared radiation energy from a target object and converts it into an electrical signal. The infrared detection device 10 sends the electrical signal to the control device 20. The control device 20 receives the electrical signal from the infrared detection device 10 and compares the signal strength with a first preset signal strength; when the signal strength is greater than or equal to the first preset signal strength, the control device 20 sends a prompt command to the prompting device 30, and the prompting device 30 issues a prompt. The target object has a surface temperature, and the infrared radiation energy is related to the surface temperature. A first preset signal has a first preset signal strength, corresponding to a first infrared radiation energy, which in turn corresponds to a first surface temperature. In this embodiment, the first surface temperature is 30°C; in other embodiments, the first surface temperature can be other temperatures, such as 32°C, 33°C, etc. When the surface temperature of the target object is greater than or equal to 30°C, the signal strength of the electrical signal converted from the infrared radiation energy of the target object is greater than or equal to the first preset signal strength. The control device 20 sends a prompting command to the prompting device 30, and the prompting device 30 issues a prompt.

[0034] In some embodiments, the control device 20 receives an electrical signal emitted by the infrared detection device 10 and compares the signal strength of the electrical signal with a first preset signal strength and a second preset signal strength. When the signal strength of the electrical signal is greater than or equal to the first preset signal strength and less than or equal to the second preset signal strength, the control device 20 sends a prompting command to the prompting device 30, and the prompting device 30 issues a prompt. The first preset signal has a first preset signal strength, corresponds to a first infrared radiation energy, and the first infrared radiation energy corresponds to a first body surface temperature; the second preset signal has a second preset signal strength, corresponds to a second infrared radiation energy, and the second infrared radiation energy corresponds to a second body surface temperature. The first body surface temperature is 30°C, and the second body surface temperature is 40°C. When the body surface temperature of the target object is greater than or equal to 30°C and less than or equal to 40°C, the signal strength of the electrical signal converted from the infrared radiation energy of the target object is greater than or equal to the first preset signal strength and less than or equal to the second preset signal strength. The control device 20 sends a prompting command to the prompting device 30, and the prompting device 30 issues a prompt.

[0035] The control device 20 controls the prompting device 30 to turn on or off via a relay or MOSFET circuit. The prompting device 30 can be a light prompting device or an sound prompting device. In this embodiment, the prompting device 30 is a light prompting device, and the control device 20 controls the light prompting device to emit a light to achieve a warning effect; in other embodiments, the prompting device 30 can also be a sound prompting device, and the control device 20 controls the sound prompting device to emit a sound to achieve a warning effect. The control device 20 is a microcontroller. The control device 20 also includes a communication module (not shown), through which the mobile terminal learns whether the prompting device 30 has issued a prompt.

[0036] When the power tool 100 is working, the prompting function of the prompting device 30 is temporarily disabled; that is, the prompting device 30 does not work when the power tool 100 is working. The prompting device 30 enters the working state after the power tool 100 stops working for T1 seconds, where 30 ≤ T1 ≤ 120. In this embodiment, the prompting device 30 enters the working state 60 seconds after the power tool 100 stops working.

[0037] When an animal approaches the power tool 100, the infrared detection device 10 receives the animal's infrared radiation energy and converts it into an electrical signal. The infrared detection device 10 sends the electrical signal to the control device 20, which then controls the alert device 30 to issue an alert. If the animal runs away, the alert device 30 will automatically stop issuing alerts once the infrared detection device 10 can no longer receive the animal's infrared radiation energy. If the animal has not run a certain distance, the infrared detection device 10 can still receive the animal's infrared radiation energy, and the alert device 30 will continue to issue alerts. In this case, to deactivate the alarm, the operator needs to operate the switch device 40.

[0038] The reminder device 30 can temporarily lose its reminder function via the switching device 40, and the reminder device 30 can regain its reminder function via the switching device 40. The switching device 40 includes an operating element 41 and a switch body 42. The operating element 41 can be operated to activate the switch body 42, thereby causing the reminder device 30 to temporarily lose or regain its reminder function. Specifically, the operator can operate the operating element 41 to temporarily lose the reminder function of the reminder device 30, and when the reminder device 30 temporarily loses its reminder function, the operator can operate the operating element 41 to regain its reminder function. After the operating element 41 is operated to regain the reminder function of the reminder device 30 and the operation is completed for T2 seconds, the reminder device 30 enters the working state, where 30 ≤ T2 ≤ 120.

[0039] In this embodiment, the operating element 41 is a pressing element. If the pressing element 41 is pressed and held, the power tool 100 starts to work normally. During the normal operation of the power tool 100, the prompting device 30 temporarily loses its prompting function. Under normal circumstances, the prompting device 30 will only resume operation 60 seconds after the power tool 100 stops working. When the power tool 100 stops working, if it is necessary to temporarily disable the prompting device 30, simply press the pressing element 41 three times consecutively. When it is necessary to restore the prompting function of the prompting device 30, press the pressing element 41 four times consecutively. After 60 seconds, the prompting device 30 will resume operation.

[0040] In this application, the power tool 100 includes an infrared detection device 10 and a warning device 30. Thermal imaging technology is used to make the warning device 30 emit light or sound to warn animals, so as to prevent animals from approaching and play a protective role for animals.
