Description

Technical Field

[0001] This utility model relates to the field of fingerprint cover technology, specifically to an ultrasonic cleaning device for fingerprint covers. Background Technology

[0002] With the development of technology, people often use fingerprint recognition as an encryption method for some terminal devices. Fingerprint recognition is a way to unlock the device by touching the fingerprint cover on the surface of the screen. During the production of fingerprint covers, they often need to be cleaned by an ultrasonic cleaning device. The ultrasonic cleaning device uses a high-frequency oscillation signal emitted by an ultrasonic generator, which is converted into a high-frequency mechanical oscillation by a transducer and propagated into the cleaning solvent. The ultrasonic waves radiate forward in the cleaning solution, thoroughly cleaning the objects in the cleaning solution.

[0003] Ultrasonic cleaning devices can generally only clean fingerprint covers, and it is not easy to dry them after cleaning, which makes the function of ultrasonic cleaning devices relatively limited. When cleaning fingerprint covers, the surface of the fingerprint covers is easily covered with the cleaned dirt, which reduces the cleanliness of the fingerprint covers. The wastewater used to clean fingerprint covers is generally discharged directly and is not easily recycled, which easily leads to the waste of water resources when using ultrasonic cleaning devices. Utility Model Content

[0008] Preferably, a flushing valve is installed at one end of the water guide pipe, and a high-pressure nozzle is fixed at the other end of the water guide pipe, with the high-pressure nozzle located above the mesh frame.

[0009] Preferably, a hanging bracket is fixed on both sides of the surface of the support frame, and a hook is fixed on both sides of the surface of the cleaning frame. The hooks are engaged with the hanging brackets, and an air blowing component is provided above the hanging brackets.

[0010] Preferably, the air blowing component includes a blower, an air guide pipe, an air outlet pipe, and a dustproof net. The air guide pipe is fixed at the top of the support frame surface, and the air outlet pipe is fixed at the bottom of the air guide pipe.

[0011] Preferably, a blower is installed inside the support frame, the input end of the blower is electrically connected to the output end of the control panel, one end of the blower is connected to the air guide pipe through a pipe, and the other end of the blower is equipped with a dustproof net through a pipe.

[0014] Preferably, a drain pipe is fixed at the bottom of the cleaning frame, one end of the drain pipe extends into the interior of the recycling bin, and a drain valve is installed on the surface of the drain pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the ultrasonic cleaning device for fingerprint covers not only enhances the functionality of the ultrasonic cleaning device and improves the cleanliness of the fingerprint cover when using the ultrasonic cleaning device, but also saves the water resources required when using the ultrasonic cleaning device.

[0016] 1. The placement mesh frame is removed by means of an air blowing mechanism. The placement mesh frame is then placed on one side of the hanger, and the hook is hung on the surface of the hanger to fix the placement mesh frame. At this time, the water inside the placement mesh frame drains into the cleaning frame. Then, the control panel is operated to make the control panel control the blower to work. The blower draws the outside air through the dust filter into the air duct and blows it out through the air outlet to blow air onto the fingerprint cover plate inside the placement mesh frame, thereby speeding up the drying speed of the fingerprint cover plate. This realizes the air blowing function of the ultrasonic cleaning device on the fingerprint cover plate, thus making the ultrasonic cleaning device more functional when in use.

[0017] 2. With a rinsing mechanism, after the sewage inside the cleaning frame is discharged, the rinsing valve can be opened first, allowing the water in the water tank to flow into the water guide pipe under gravity and be sprayed out through the high-pressure nozzle to rinse the fingerprint cover plate inside the mesh frame. This washes away the dirt on the surface of the fingerprint cover plate and pushes it into the cleaning frame. After rinsing is complete, the rinsing valve can be closed, and then the rotating column can be rotated to move the water guide pipe to one side of the cleaning frame, so that the water guide pipe will not block the mesh frame. This enables the ultrasonic cleaning device to rinse the fingerprint cover plate, thereby improving the cleanliness of the fingerprint cover plate when using the ultrasonic cleaning device.

[0018] 3. Equipped with a recycling mechanism, after cleaning, the drain valve can be opened to allow the wastewater inside the cleaning frame to drain into the recycling tank through the drain pipe. After the wastewater inside the cleaning frame is drained, the control panel can be operated to control the water pump. Under the action of the water pump, the water filtered through the activated carbon layer is guided into the cleaning frame for the next set of fingerprint covers to be cleaned. After a period of time, the activated carbon layer can be extracted for cleaning or replacement, thus realizing the water recycling function of the ultrasonic cleaning device and saving the water resources required for the use of the ultrasonic cleaning device.
