In the prior art, the ultrasonic cleaning technology is to use an ultrasonic cleaning machine as a container, soak a part to be cleaned in the container, and achieve the purpose of cleaning under the action of ultrasonic waves.

However, unlike the rigid articles whose surface stains are liable to fall off by vibration, the clothes are generally made of various fibers, have soft texture and ultrasonic wave absorption effect, and the ultrasonic wave washing device has large ultrasonic wave loss when washing the clothes; in addition, in the existing ultrasonic washing device, generally, a high-frequency ultrasonic wave transducer emits a high-frequency ultrasonic wave to wash liquid in a tank to generate a plurality of tiny high-frequency bubbles, and the tiny high-frequency bubbles continuously hit the surface of the clothes to be washed to generate resonance with stains, oil stains and the like on the surface of the clothes to be washed, so that the stains and the oil stains are separated. The stains of cloth and cotton products like clothes are absorbed in the clothes or permeate into molecules or atomic tissues of the clothes, and the high-frequency air bubbles hit the clothes to generate resonance only on the surface of the clothes, so that the cleaning effect of the ultrasonic washing device on the clothes directly placed in the cleaning tank is limited, and the effect on local stubborn stains is not ideal.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example one

As shown in fig. 1 to 11, the present embodiment provides an ultrasonic washing apparatus, which includes a body 100 and a cover 1, wherein the cover 1 is openably/closably disposed on the body 100, the body 100 is provided with an ultrasonic generating device 200 and a washing tank 400 for containing a washing liquid 5, the ultrasonic generating device 200 has an ultrasonic vibrating end for generating vibration, and the ultrasonic vibrating end faces the washing tank 400; when the cover body 1 is closed, the ultrasonic wave generating device 200 and the cleaning tank 400 are covered in the cover body 1, and when the cover body 1 is opened, the clothes 4 to be cleaned can be put into the cleaning tank 400.

The ultrasonic washing device of the embodiment can be a wall-mounted type, fixed on a wall body, or fixed at a position suitable for installation and use, such as a fixed plate, and can realize the function of the ultrasonic washing device; the table can also be a table top type, such as fixed at a hand washing table and the like.

The ultrasonic washing device of the embodiment can be used for washing parts of clothes which are not easy to wash, such as collars, cuffs, edges of clothes and the like, and can also be used for washing local stains of the clothes or articles made of soft materials. When the clothes of a user are accidentally stained with stains, the clothes can be worn and treated in time, so that the stains are prevented from being deposited, and the clothes can be applied to various places.

The ultrasonic wave generator 200 and the cleaning tank 400 of the present embodiment are installed on the body 100100 of the ultrasonic cleaning apparatus, and are installed in a vertically corresponding manner. After at least partial clothes 4 to be washed are placed between the ultrasonic wave generating device 200 and the washing tank 400, the clothes 4 to be washed are soaked by the washing liquid 5 in the washing tank 400, and can be completely soaked or partially soaked; the upper surface of the soaked clothes 4 to be washed is contacted with the ultrasonic vibration end of the ultrasonic generating device 200, when the ultrasonic generating device 200 works, the stains of the clothes 4 to be washed and the ultrasonic vibration end generate resonance, the resonance can directly reach the deep layer of the clothes fiber, and stubborn stains on the surface and the deep layer of the clothes can fall off along with the resonance of the ultrasonic vibration wave, so that the effect of removing the stains is better.

The laundry is not required to be completely soaked in the cleaning tank 400, and the laundry is only required to be contacted with the ultrasonic vibration end of the ultrasonic wave generating device 200 after being soaked to achieve resonance, so that the effect of thorough cleaning is achieved. Because the scheme only needs to soak the clothes, the ultrasonic generating device does not need to be placed in liquid to generate resonance, only a small amount of liquid is needed, the needed cleaning tank 400 is shallow, and the depth of the cleaning tank is only needed to be larger than that of the thicker clothes. Therefore, the volume of the cleaning tank 400 is small, and a good cleaning effect can be achieved only by a small amount of water, so that the occupied space can be saved, the water consumption can be greatly saved, and the cleaning process is convenient and rapid.

The ultrasonic vibration end of the ultrasonic wave generating device 200 is in contact with the liquid level in the washing tank 400 or has a certain distance such that at least the lower surface of the laundry 4 is in contact with the liquid level of the washing liquid 5 when the upper surface of the laundry 4 is in contact with the ultrasonic vibration end.

The liquid level of the present embodiment may be a liquid level that is set to a fixed height after the washing liquid 5 enters the washing tank 400, and the height of the liquid level may be set according to the specification and size of the washing tank 400.

When the ultrasonic vibration end of the ultrasonic wave generating device 200 is in contact with the liquid level in the cleaning tank 400, the laundry 4 is completely soaked in the cleaning tank 400, and simultaneously the upper surface of the laundry 4 is in contact with the ultrasonic vibration end. When the ultrasonic wave generating device 200 works, the ultrasonic wave vibration directly reaches the clothes, so that the consumption of the ultrasonic wave is reduced, meanwhile, the high-frequency ultrasonic wave generated by the ultrasonic wave vibrates the liquid soaked in the clothes 4 to be washed, a plurality of tiny high-frequency bubbles are generated, and the tiny bubbles continuously hit the surface and the inner layer of the clothes to be washed, generate resonance with stains on the surface and the inner layer of the clothes to be washed, and enable the stains to fall off.

When the ultrasonic vibration end of the ultrasonic wave generating device 200 has a certain distance from the liquid level in the washing tank 400, the distance needs to be the largest enough to allow the lower surface of the laundry 4 to contact the liquid level of the washing liquid 5 when the upper surface of the laundry 4 contacts the ultrasonic vibration end. Therefore, the clothes 4 to be washed can be ensured to be continuously soaked in the washing liquid 5, so that resonance is achieved during ultrasonic work, and the washing effect is achieved.

The cover body 1 arranged on the ultrasonic washing device can cover the ultrasonic generating device 200 and the cleaning tank 400 in the cover body 1, can prevent dust, keeps the neatness of the inside of the ultrasonic washing device, and can greatly improve the overall attractiveness of the ultrasonic washing device while avoiding the adverse effect of the external environment on the ultrasonic generating device 200.

In a further embodiment, the cover 1 has a cavity 2, the cover 1 covers the body 100 after being closed, the cavity 2 of the cover 1 and the body 100 form a closed space 3, and the ultrasonic generator 200 and the cleaning tank 400 are both located in the closed space 3.

The shape and size of the cavity 2 of the cover body 1 are matched with those of the body 100, and after the cover body 1 is closed, on one hand, the cavity 2 and the body 100 form a closed space 3 which can contain and protect the ultrasonic generating device 200 and the cleaning tank 400, so that a regular appearance is formed, and the damage of packaging and transportation is avoided; the ultrasonic wave generating device 200 and the cleaning tank 400 are isolated from the external environment, so that the cleanness of the inside of the ultrasonic wave cleaning device is kept, and the service life of the ultrasonic wave cleaning device can be prolonged.

The cavity 2 of the cover body 1 has at least one opening, and the cover body 1 can cover the upper part or the top of the body 100 and can also cover the side part of the body 100, so that a closed space can be formed with the body 100, and the purposes of dust prevention and protection of the ultrasonic wave generating device 200 and the cleaning tank 400 are achieved.
