[0002] The spread of the pandemic has heightened expectations for surface cleanliness. Handheld air guns can be used to remove dust from surfaces, but these contact methods can cause secondary contamination. Ultrasonic cleaners can be used, but the cleaning fluid is difficult to remove. Automatic dust collectors can be used, but the dust collecting paper requires frequent replacement, which is cumbersome and wastes resources. Disinfection with detergents and wiping with cloths is common, but often offers little protection against bacteria and viruses.

[0003] The present invention provides a self-generating brush, which is simple to operate, light and handy, easy to carry, does not require any power supply, can be self-driven and powered, generates Maxwell pulse electric field and pulse microcurrent, acts on the surface of the object to be cleaned, can effectively sterilize and remove mites, and clean the surface of the object. This is a brand-new technology, which is applied to the field of object cleaning and greatly facilitates people's lives.

[0004] Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a self-generating brush. The brush comprises a self-generating array and a base. The brush generates a force between the brush and the surface of the object being cleaned, generating a Maxwell pulse electric field and a pulsed microcurrent, which act on the surface to achieve a sterilizing and mite-removing cleaning effect. The brush does not require any external power supply, is simple to operate, and is portable, allowing it to be used to clean surrounding objects anytime, anywhere.

[0006] This innovative self-generating brush can generate an open-circuit voltage of up to 2000 volts and a short-circuit current of up to 200 microamperes. The pulsed electric field and current generated by this brush, made from special materials, can light a 1-watt lightbulb. The self-generating brush combines the effects of a Maxwell displacement electric field with a pulsed current, effectively killing bacteria and removing mites on surfaces without the need for an external power source.

[0007] The self-generating brush is composed of a self-generating array and a substrate. The self-generating brush generates force on the surface of the object to be cleaned, and can generate Maxwell pulse electric field and pulse microcurrent, which act on the surface of the object to be cleaned, can sterilize and remove mites, thereby achieving the effect of cleaning the surface of the object.

[0008] The force may be applied in a vertical direction, a horizontal direction, or an oblique direction, wherein the force includes friction, contact, collision, or impact.

By rubbing or tapping the self-generating brush, the layers of the self-generating array are constantly in contact and dislocated with each other, generating Maxwell pulse electric fields and pulse microcurrents, which have the effect of cleaning, sterilizing and removing mites.

[0014] There are movable power generators with strong electrification performance between the layers of the layered self-generating brush.

[0015] The structure of the base may be, but is not limited to, a hand-held shape, a long-handled shape, a double-sided shape, a bed-sweeping shape, a roller shape, a sickle shape, or a mop shape.

[0042] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0043] The following describes a self-generating brush in detail. The present invention provides a self-generating brush comprising a self-generating array and a base. The brush acts on the surface of the object being cleaned, generating a Maxwell pulse electric field and pulsed microcurrent through friction with the self-generating array, thereby achieving a sterilizing and mite-removing cleaning effect.

[0044] Figures 1-11 illustrate an embodiment of a self-generating brush, including a self-generating array and a substrate. Figure 12 clearly illustrates the operating principle of a self-generating brush. Because this is a completely new discovery, it is not easily understood by those skilled in the art. Recent research has found that when objects rub against each other, an electric field is generated. After the friction stops, an electrostatic field is generated, which can persist for a period of time. However, as long as the friction continues, a continuously changing electric field is generated, which is known as the Maxwell displacement field. Because there is a certain potential difference between the outer surface and the inner portion of the microbial cell membrane, when an external electric field is applied to the cell, the potential difference between the inner and outer membranes increases, dramatically increasing the permeability of the cell membrane. Numerous small pores appear in the cell membrane, causing irreversible damage, leading to irreversible cell rupture and eventual death. The continuously changing Maxwell displacement field can produce a more effective bactericidal and mite-removing effect, thereby killing or inactivating harmful microorganisms.

[0045] Optionally, the self-generating brush is composed of a layered self-generating array and a substrate. The self-generating brush is applied to the surface of the object to be cleaned, and Maxwell pulse electric field and pulse microcurrent are generated by rubbing or tapping the self-generating array, which plays a role in cleaning, sterilizing and removing mites.

[0046] Optionally, a power generating body with strong electrification performance is attached to the surface or inside of the self-generating array.

[0047] Optionally, the self-generating brush is composed of two or more layers of layered self-generating arrays and a substrate. The self-generating brush is applied to the surface of the object to be cleaned. By rubbing or tapping the self-generating array, the layers are constantly in contact and dislocated with each other, generating Maxwell pulse electric fields and pulse microcurrents, which play a role in cleaning, sterilizing and removing mites.

[0048] Optionally, there are movable power generators with strong electrification properties between the layers of the self-generating array.

[0049] Optionally, the self-generating brush is composed of a columnar or filamentary self-generating array and a base. The self-generating array continuously rubs against the object to be cleaned to generate Maxwell pulse electric field and pulse microcurrent, which act on the surface of the object to be cleaned to achieve sterilization and mite removal.

[0050] Optionally, the columnar or filamentary wire-arranged self-generating array can be a polymer wire such as perfluoroethylene propylene copolymer or polytetrafluoroethylene, or a polymer wire with electrets such as barium titanate, paraffin, rubber, hydrocarbon or solid acid added, or a composite thereof.

[0051] Optionally, the shape and structure of the generator are not limited, and can be particles, tubes, sheets, meshes, flocs, spheres, rods, including but not limited to nanowires, nanotubes, nanoparticles, nanorods, nanoflowers, nanogrooves, microgrooves, nanocones, microcones, nanospheres and microspherical structures.

[0052] Optionally, the material used to manufacture the self-generating array may be one or more of a mesh structure, a textile structure, a dense structure, a honeycomb structure, and a porous structure.

[0053] Optionally, the manufacturing material of the self-generating array is one of flexible materials, rigid materials or rigid-flexible integrated materials, including but not limited to textile materials, silk materials, cotton materials, chemical fiber materials, polymer materials, organic materials, inorganic materials, and organic-inorganic composite materials.
