Abstract

The invention discloses a local stain removing device with combined action of vacuum and ultrasound, which comprises a handheld terminal and a machine body; the handheld terminal 1 includes an ultrasonic transducer, a transducer holder, and a cleaning adsorption base plate. The front end part of the amplitude transformer is positioned at the water outlet part, so that a cavitation zone is formed at the front end part of the amplitude transformer after water flows flow out of the cavity flow outlet of the water outlet channel. When water in the cavitation region begins to diffuse outwards due to capillary action or water flow action, negative pressure is formed at the peripheral vacuum adsorption port (arranged around the water outlet) part, so that the water flows to the gas-liquid adsorption cavity, and further water stain or water flow expansion is prevented or stopped. The cleaning effect and the vacuum adsorption under the action of ultrasonic cavitation are combined, the device can not only adapt to the stain treatment on the surface of a single-layer fiber object, but also adapt to thick fiber objects, and water flowing out of a water outlet can not permeate into other areas in a large amount due to the vacuum effect of the adsorption port, so that large water stain traces are avoided.

Description

Local stain removing equipment with combined action of vacuum and ultrasound and method for cleaning local stains on surface of fiber

Technical Field

The invention relates to a device and a method for the local stain-cleaning treatment of fibrous material.

Background

For young white collars, shirts are typically changed faster, while generally soiled collars and cuffs are the only ones. For high end clothing, localized soiling may also lead to the need to enter a dry cleaner for cleaning. When the clothes are frequently thrown into the washing machine for washing, the clothes can be easily deformed and worn in a shortened way; and frequent dry cleaning is also a waste of social resources.

The valuable clothes are stained with local stains, and the service life of the clothes is shortened due to frequent dry cleaning. Some garments are not suitable for dry cleaning. Heavy winter clothes are difficult to treat local stains on the surface, and the problem can be solved to a certain extent by using a cleaning agent mode, but the stains can be separated from the surface and remain in the clothes. Furniture bedding, carpets, textile sofa fabrics, curtains and the like are difficult to be washed by a washing machine because of the excessive thickness and the difficulty in disassembling. The stains on the collar and the cuffs are difficult to remove by a washing machine, and the effect can be achieved only by washing with hands for the second time.

Ultrasonic cavitation provides a good solution in oil and stain removal. The high temperature and high pressure shock waves generated when the bubbles collapse by compression reduce the adhesion between the dirt and the cleaned object. Causing the damage and the separation of the dirt, and simultaneously, the air bubbles can also be drilled into gaps and cracks to vibrate, so that the dirt falls off.

The invention patent 201210274953 discloses a washing device capable of realizing local washing, relating to a washing device capable of realizing local washing. The washing liquid container is provided with a liquid outlet and a liquid return port. When local washing is carried out, the parts to be washed are clamped by the clamp, the valve is closed, so that the washing liquid is firstly conveyed to the clamped parts of the clothes, the local supply of the washing liquid is realized, and the washing effect is improved. There is a problem that it is not suitable for heavy clothing or household goods. The clamping part is difficult to clamp thick clothes.

This structure is particularly useful in the cleaning of stains on the surface of heavy clothing or household items (such as fabric sofas): after the cleaning water reaches the surface, it spreads continuously outward (in the direction of the web) and inward (in the direction perpendicular to the surface of the web) due to capillary action. In the process of spreading, the dirt is carried and spread together.
