The present disclosure relates to an apparatus and a method for wafer cleaning. The apparatus can include a wafer holder configured to hold a wafer; a cleaning nozzle configured to dispense a cleaning fluid onto a first surface (e.g., front surface) of the wafer; and a cleaning brush configured to clean a second surface (e.g., back surface) of the wafer. Using the cleaning fluid, the cleaning brush can clean the second surface of the wafer with a scrubbing motion and ultrasonic vibration.

A liquid eyeliner pen having a liquid storage function includes a brush sleeve having a brush sleeve body. At least one air inlet hole extending along an axial direction of the brush sleeve body is configured on the brush sleeve body at a position close to the front shaft end thereof in a through manner. The front side of the air inlet hole is exposed outside a brush sleeve base. At least one first air vent extending along the axial direction of the brush sleeve body is further configured on the outer layer sidewall of the brush sleeve body. A front side of the first air vent intercommunicates with the air inlet hole, a rear side of the first air vent intercommunicates with a second air vent on the diverter base. At least one liquid storage groove unit is configured on the inner layer sidewall of the brush sleeve body.

The present invention relates to a brush assembly for cleaning metal, the assembly comprising one or more brush heads, each brush head comprising a bundle of conductive filaments, having a working end adapted for contacting metal, and a terminal end, the brush head connectable to an electricity supply, and a housing connected to and retaining at least one sheath, each sheath at least partially surrounding at least one brush head, wherein each brush head and its respective sheath are movable in relation to each other by operating an adjustment mechanism and the working end of the brush head and the sheath are selectively fixable in relation to each other.

A scrubbing device is disclosed, and includes a body and a driving shaft, wherein the body is provided with a sealing mechanism configured to seal a connection portion between the driving shaft and the body. The sealing mechanism includes a sealing member sleeved on the driving shaft. The sealing member has an end that is attached, sealed, and connected to a sidewall of the body. The driving shaft is sleeved with a first sealing ring made of a rigid material and a second sealing ring made of a soft material. The first sealing ring and the second sealing ring are both in contact with an inner wall of the sealing member.

A dust-containing gas treatment apparatus includes a cylindrical treatment room configured to introduce gas containing dust and remove the dust from the gas, a catcher including a brush with hair planted in a support in the cylindrical treatment room and configured to catch the dust contained in the gas, a liquid sprayer in the cylindrical treatment room, a rotary driver configured to rotate the catcher and a stirrer, a gas introduction portion configured to introduce the gas containing the dust, a gas discharge portion configured to discharge the gas and the removed dust from the cylindrical treatment room, and a liquid discharge portion configured to discharge a liquid containing the removed dust.

A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. At the end of the handle is a pointed end defined by a pointed tip. The pointed end and pointed tip operates in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. The pointed end removes hair or other debris that are in or near a crease or crevice of the fabric. This operational engagement position is one of a number of other operational engagement positions for the pet hair removal apparatus.

Disclosed is a cleaning apparatus. The apparatus has a handle adapted to releasably engage with a connection member: a connection member adapted to releasably engage with a handle, a cleaning head and a stand; a cleaning head adapted to releasably engage with the connection member; and a stand adapted to releasably engage with the connection member; the apparatus arranged such that when the handle, connection member and cleaning head are engaged they form a handheld cleaning device which is able to releasably engage with the stand for storage.

Disclosed are a roller brush, a floor brush, and a vacuum cleaner. The roller brush of the present disclosure includes a base body, wherein the axial center line of the base body is a, the outer surface of the base body is provided with at least one group of cyclonic grooves, each group of cyclonic grooves includes at least one first groove, the surface of a cylinder passing through a first position and taking a as the axial center line is taken as A, and the surface of a cylinder passing through a second position and taking a as the axial center line is taken as B, and the distance D between A and B in a radial direction perpendicular to a is greater than 2 mm. According to the roller brush of the disclosure, the problem of the hair entangled around the roller brush is effectively solved.

Disposable clean up utensils that can be incorporated into a box or other container, comprised of an apparatus, an incised and scored blank, from which clean up utensils, such as a combination bristle brush and paddle, a dustpan, a paddle and a scraper, may be formed by separating them from the apparatus, said apparatus comprising a flat sheet of bendable material comprising a combination bristle brush and paddle comprising a plurality of angled incised bristle lines; a scraper; a paddle; a dustpan comprising a dustpan handle fold line; an intersect at the rear of the dustpan; a right back score and fold mark; a left back score and fold mark; a dustpan handle fold line; a plurality of rear pan inclines; a plurality of sidewall score and fold marks; a pan-to-floor interface; an incised line bounding dustpan; and a bristle brush score and fold mark.

The present invention provides a cleaning brush and a cleaning apparatus that can effectively discharge dust, removed from a dresser disk of a CMP apparatus upon cleaning the dresser disk, to the outside of the cleaning system in order to prevent the dust from being again deposited on the dresser disk. A cleaning brush includes a large number of brushes formed to protrude on its top surface, vertical through-holes and into which a nozzle for ejecting a cleaning fluid is inserted, and a recessed groove formed on a lower surface that lower ends of the through-holes and face. It is configured such that dust deposited onto the brushes upon cleaning the dresser disk is discharged to outside from the recessed groove through a gap between the surrounding of the nozzle and the inner surface of the through-holes and together with the cleaning fluid.
