[0033] Further, see Figure 2 According to some embodiments of the utility model, the dimming glass also includes a temperature sensor 420, which is arranged indoors.

At the same time, the control chip 300 can also receive the first touch signal from the touch screen 130 and switch the automatic adjustment mode to the manual adjustment mode. However, at this time, the control chip 300 cannot receive the remaining touch signals of the touch screen 130 or cannot provide feedback on the remaining touch signals; when the control chip 300 switches to the manual adjustment mode, the control chip 300 can receive the touch signal from the touch screen 130, and the user can The touch screen 130 can be touched with a specific second gesture, and the touch screen 130 outputs a corresponding second touch signal.

[0038] Reference Figure 3 The control process of switching the control chip 300 from the manual adjustment mode to the automatic adjustment mode includes the following steps S100 to S130, wherein:

[0039] Step S100: the user touches the touch screen 130 with a first gesture.

[0040] Specifically, the touch screen 130 is preset with a first gesture. For example, the first gesture can be a circle, but is not limited to this. The user touches the touch screen 130 with a finger and slides in a circle to form a circular closed area, thereby completing the first gesture. The touch screen 130 recognizes the user's touch operation and generates a first touch signal, and then transmits the first touch signal to the control chip 300.

[0041] Step S110: the control chip 300 receives the first touch signal and switches to the automatic adjustment mode.

[0042] Specifically, the control chip 300 is originally in the manual adjustment mode, and switches to the automatic adjustment mode after receiving the first touch signal. At this time, the control chip 300 can receive the first touch signal from the touch screen 130, the light intensity signal from the light sensor 410, and the temperature signal from the temperature sensor 420 and make corresponding feedback.

[0043] Step S120 : the light sensor 410 collects outdoor light intensity and transmits a light intensity signal to the control chip 300 ; the temperature sensor 420 collects indoor temperature and transmits a temperature signal to the control chip 300 .

[0044] Step S130: the control chip 300 controls the voltage regulating circuit 200 to increase or decrease the voltage.

[0045] Specifically, the light sensor 410 is arranged outdoors to collect the outdoor light intensity and output a light intensity signal. The temperature sensor 420 is arranged indoors to collect the indoor temperature and output a temperature signal. When in the automatic adjustment mode, the control chip 300 can simultaneously receive the light intensity signal and the temperature signal, and control the voltage adjustment circuit 200 to adjust the voltage, thereby adjusting the transparency of the dimming film 120 in real time according to the indoor and outdoor environment, realizing intelligent control with a high degree of automation, and improving the accuracy of the light transmittance adjustment, thereby improving the user experience.

[0047] Step S200: The user touches the touch screen 130 with a first gesture.

[0048] Specifically, the touch screen 130 is preset with a first gesture. For example, the first gesture can be a circle, but is not limited to this. The user touches the touch screen 130 with a finger and slides to form a circular closed area to complete the first gesture. The touch screen 130 recognizes the user's touch operation and generates a first touch signal, and then transmits the first touch signal to the control chip 300.

[0049] Step S210: the control chip 300 receives a first touch signal and switches to a manual adjustment mode.

[0050] Specifically, the control chip 300 is originally in the automatic adjustment mode, and switches to the manual adjustment mode after receiving the first touch signal. At this time, the control chip 300 can receive the first touch signal, the second touch signal and the third touch signal from the touch screen 130 and make corresponding feedback.

[0051] Step S220: the user touches the touch screen 130 with the second gesture or the third gesture.

[0052] Step S230: the control chip 300 controls the voltage regulating circuit 200 to increase or decrease the voltage.

[0053] Specifically, the touch screen 130 is preset with a second gesture and a third gesture. For example, the second gesture can be a horizontal stroke, and the third gesture can be a vertical stroke, but it is not limited to this. The user touches the touch screen 130 with a finger and slides horizontally to form a horizontal stroke, thereby completing the second gesture. The touch screen 130 recognizes the user's touch operation and generates a second touch signal, and then transmits the second touch signal to the control chip 300. The control chip 300 controls the voltage regulation circuit 200 to increase the voltage; the user touches the touch screen 130 with a finger and slides vertically to form a vertical stroke, thereby completing the third gesture. The touch screen 130 recognizes the user's touch operation and generates a third touch signal, and then transmits the third touch signal to the control chip 300. The control chip 300 controls the voltage regulation circuit 200 to reduce the voltage, thereby realizing manual adjustment of the transparency of the dimming film 120 to meet the different needs of users.

The control chip 300 can receive the voltage value and compare it with a preset value. When the voltage value is greater than the preset value, the control chip 300 controls the switch component 510 to disconnect the circuit, thereby protecting the circuit and effectively preventing the power supply component 500 from outputting too high a voltage and causing damage to the dimming film 120.

[0058] Further, see Figure 2 According to some embodiments of the present invention, the dimming glass further includes a photovoltaic element 530 , which is disposed outdoors and is electrically connected to the control chip 300 .
