Description

Technical Field

[0001] The utility model relates to the technical field of reversible metal electrodeposition device auxiliary internal wrinkle elimination, in particular to an ultrasonic device for cleaning deposited wrinkles of a flexible reversible metal electrodeposition device. Background Art

[0002] Electrochromic devices are materials that can change their optical properties through an external electric field. They are often used to adjust transparency or change color, such as electric car skylight glass, smart glasses and smart dimming glass. Reversible metal electrodeposition devices are one type of electrochromic devices. However, with the long-term use of reversible metal electrodeposition devices, especially after multiple cycles, the thin film deposited on the surface of the device will be difficult to dissolve, which seriously affects the performance and stability of the device. It can be understood that the reversible metal electrodeposition device is made of two conductive glass conductive surfaces facing each other, and the electrolyte is filled in the middle. The electrolyte will react when the voltage is applied. When used for a short time, the wrinkles formed on the reversible metal electrodeposition device will fade when the power is not connected or the reverse voltage is connected. However, as the use time increases, the silver film deposited on the conductive surface of one of the conductive glasses will not fade when the power is turned off or the reverse voltage is connected, causing the conductive glass to have persistent "wrinkles". Not only will it cause a decline in appearance, but it will also cause wrinkles in the subsequent deposition, which will continue to accumulate, resulting in a serious decline in the device's aesthetics and cyclic reversibility. Through data research and analysis, we know that the growth process of the silver film generates compressive growth stress. When the growth stress exceeds the critical value of the system, the silver film buckles and becomes unstable under the compressive stress, forming micro-wrinkles. In addition, the annular stress caused by the surface tension difference can also lead to the formation of wrinkles.

[0003] At present, some solutions have been proposed for the problem of thin film deposition in reversible metal electrodeposition devices, including the use of chemical solvents or electrolytes to clean the device surface. However, these methods usually require opening the device and replacing the electrolyte, which is complicated. Therefore, there is an urgent need for a new technology that can effectively reset the reversible metal electrodeposition device and restore its performance without opening the device or replacing the electrolyte.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Specific implementation plan 1: Combine Figures 1 to 4 As shown, the utility model provides an ultrasonic device for cleaning deposited wrinkles of a flexible reversible metal electrodeposition device, comprising a power supply, an ultrasonic generator and a piezoelectric ceramic ultrasonic transducer, wherein the power supply is connected to the ultrasonic generator, and the ultrasonic generator is used to convert industrial frequency electricity into a high-frequency alternating current signal that matches the piezoelectric ceramic ultrasonic transducer; the ultrasonic generator is connected to the piezoelectric ceramic ultrasonic transducer, and the piezoelectric ceramic ultrasonic transducer is used to be placed on the surface of the reversible metal electrodeposition device, and the piezoelectric ceramic ultrasonic transducer is used to convert the high-frequency alternating current signal into ultrasonic waves so as to use ultrasonic waves to vibrate and clean the deposited film on the surface of the reversible metal electrodeposition device;

[0029] The piezoelectric ceramic ultrasonic transducer includes a plurality of evenly distributed piezoelectric ceramic sheet units 2 and surrounding edge-sealing connectors 1. Each piezoelectric ceramic sheet unit 2 includes a piezoelectric ceramic sheet 220 at the center. An insulating nest 210 is provided outside the piezoelectric ceramic sheet 220. Two adjacent piezoelectric ceramic sheets 220 are connected by a flexible connector 230.

[0030] Preferably, the flexible connectors 230 of the piezoelectric ceramic sheet unit 2 located at the edge are all connected to the corresponding edge-sealing connectors 1 , and the edge-sealing connectors 1 are flexible edge-sealing connectors 1 .

[0031] Preferably, the insulating nest 210 may be a plastic nest, and the plastic nest is a flexible plastic nest, and the flexible connector 230 is connected to the piezoelectric ceramic sheet 220 in the flexible plastic nest.

[0032] Preferably, the insulating nest 210 includes an upper insulating nest 211 and a lower insulating nest 212, and a piezoelectric ceramic sheet 220 connected with a flexible connector 230 is arranged between the upper insulating nest 211 and the lower insulating nest 212.

[0033] Preferably, the flexible connector 230 is a flexible connecting wire, and the edge sealing connector 1 is a flexible connecting wire.

[0036] The piezoelectric ceramic ultrasonic cleaning transducer used in the utility model performs ultrasonic treatment on the device based on the piezoelectric effect and the vibration action of ultrasonic waves. When an external power source is applied to the electrode through an ultrasonic generator, the piezoelectric ceramic sheet 220 is deformed under the action of the electric field to generate high-frequency vibrations, which are transmitted to the liquid through the outer shell to form a dense ultrasonic beam.

The actual effect can be clearly seen that there are no obvious wrinkles on the surface of the reversible metal electrodeposition device.
