Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of personal hygiene cleaning equipment, in particular to an ultrasonic hand washer. Background Art
[0002] With the improvement of people's requirements for hand hygiene, handwashing has become an indispensable part of daily life. However, traditional handwashing methods often cannot thoroughly clean the stains and bacteria on the skin of the hands, especially in special environments such as hospitals and laboratories, where the requirements for hand cleaning are higher. Therefore, it is necessary to design an ultrasonic handwashing device that is easy to standardize and can clean hands efficiently and quickly. Traditional handwashing methods often rely on manual rubbing and rinsing with running water. Although this method can remove some stains and bacteria, the effect is limited, especially in removing stubborn stains and deep-layer bacteria. In addition, in public places, due to the high frequency of use of handwashing equipment, the risk of bacterial cross-infection is relatively high. Moreover, after the post-epidemic era, people also need a standardized handwashing device that can efficiently ensure the handwashing efficiency. Summary of the Invention
[0003] The technical problem to be solved is to design a device that can clean hands efficiently, quickly and safely.
[0004] The technical solution of the present invention is an ultrasonic intelligent hand washer, which includes: a washbasin, a liquid soap container, an ultrasonic module, a single-chip microcomputer, a water pipe, and a water pump; the washbasin is filled with water and has an opening at the top, and hands can be inserted into the washbasin through the opening at the top; the liquid soap container is arranged above the washbasin, the water pump is arranged on the outer wall of the side of the washbasin, one side of the water pipe is connected to the water pump, and the other side passes through the side wall of the washbasin and extends into the interior of the washbasin. The part of the water pipe inside the washbasin is located below the liquid soap container, and the liquid soap container is connected to the water pipe through a straw; the ultrasonic module is located at the bottom of the washbasin; the single-chip microcomputer controls the opening and closing of the ultrasonic module and the water pump.
[0005] Further, one or more sponge barrels are also arranged in the washbasin, and each sponge barrel is driven to rotate by a motor.
[0006] Further, a battery is also arranged on the outer wall of the washbasin to supply power to each electrical appliance of the hand washer.
[0007] Further, a drain outlet is arranged at the bottom of the side wall of the washbasin. The drain outlet is strip-shaped, and the size of the drainage is controlled by a drainage control bar.
[0008] Advantageous Effects: By adopting the above technical solution, the ultrasonic handwashing device of the present utility model has the following advantageous effects:
[0009] (1) High - efficiency cleaning: Through the cavitation effect and impact force of ultrasonic waves, stains and bacteria on the hand skin can be quickly removed, and the cleaning effect is better than traditional hand - washing methods.
[0010] (2) Safe and hygienic: When ultrasonic waves act on the hand skin, it will not cause damage to the skin. At the same time, it can reduce the risk of bacterial cross - infection and ensure the health of users.
[0011] (3) Easy to operate: Users only need to put their hands into the sink to carry out the cleaning, without complex operations.
[0012] (4) Comfortable experience: The design of the sink pays attention to the user experience, using comfortable materials and an ergonomic shape, making users feel comfortable during the cleaning process.
[0013] In summary, the ultrasonic hand - washing machine of the present utility model can solve problems such as poor cleaning effect and high risk of bacterial cross - infection in traditional hand - washing methods, and provide an efficient, safe and hygienic hand - cleaning solution for users.

Detailed Embodiments
[0020] The hand washer of the present invention includes a washbasin, an ultrasonic module, a switch, and a power supply system. An infrared sensor is provided at the opening of the washbasin, and this infrared sensor determines whether a hand reaches into the washbasin; if so, each module performs a hand-washing action. The ultrasonic module is installed inside the washbasin and can generate ultrasonic vibrations. Through the cavitation effect and impact force of the ultrasonic waves, the hand sanitizer and water are mixed into fine foam and act on the hand skin, thereby effectively removing stains and bacteria. The switch is used to start the water inlet and the ultrasonic device; the power supply system provides power for the ultrasonic module. The washbasin is designed in an ergonomic shape to improve the comfort of use. In addition, the hand washer can also be equipped with a water temperature adjustment system to meet the different water temperature requirements of users in different seasons. The two ends of the sponge barrel in the washbasin are respectively arranged on the opposite side walls of the washbasin, and the motor driving the sponge barrel is arranged on the outer wall of the washbasin.
[0021] In specific implementation, the user can put the hand into the washbasin, and the ultrasonic module starts to work, generating ultrasonic vibrations, mixing the hand sanitizer and water into foam, and acting on the hand skin. The user only needs to put the hand into the washbasin of the hand washer, so that the stains and bacteria are thoroughly cleaned. After the cleaning is completed, the waste water is automatically discharged; the drain outlet is strip-shaped.
[0022] ① Washbasin size: 0.28m x 0.28m x 0.39m (depth);
[0023] ② Sponge roller size: outer diameter 52mm, inner diameter 20mm, wall thickness 16mm, the axial distance between the upper and lower sponge rollers is 8cm, which can ensure the cleaning effect. The sponge rotates outwards and cannot rotate inwards to ensure safety.
[0024] ③ Water pipe size: outer diameter 12mm, inner diameter 10mm, wall thickness 1mm, which is consistent with the common diameter used for the water circulation of fish tanks on the market and does not require customization. The straw connecting the water pipe and the hand sanitizer container has the same size.
[0025] ④ Ultrasonic power: The ultrasonic transmitter selects a single bottom vibration plate, and the power is maintained at 0.3 - 0.5W per square centimeter. The height of the selected tank body is about 40cm. Generally, calculated by the rising power, it is 11w / L. On the other hand, considering the ultrasonic cleaning effect and economy, the frequency is generally selected between 20 - 130KHz. After consulting the papers, it is determined to be about 30 - 60kHz.
[0026] ⑤ Sponge barrel rotation speed: The motor is selected to rotate one circle in two seconds, that is, the rotation speed is 0.5 revolutions per second.
