The washing brush includes a handle part, a shaft part connected to the handle part, a sliding part configured to slide along the shaft part, a strip part coupled to the lower end part of the shaft part and lower part of the sliding part, a brush part attached to the outside of the strip part; and a position adjusting part configured to adjust a relative position of the shaft part. The sliding part is pressed to spread the strip part and the spread can be varied by the position adjusting part by adjusting the relative position of the sliding part with respect to the shaft part. A washing brush is provided that can simply and quickly wash a cylindrical container by allowing a washing part to be spread according to the shape of a container.

A rotary cleaning tool assembly for cleaning difficult to clean articles includes a housing that defines an interior space. A power module and a motor are coupled to the housing and are positioned in the interior space. The motor is operationally coupled to the power module. Each of a plurality of cleaning heads is selectively couplable to the housing so that the cleaning head is operationally coupled to the motor. The motor is positioned to rotate the cleaning head to clean an article.

A pipe de-burring assembly for de-burring a pipe and a pipe fitting includes a cylinder that has a pair of wells each extending therein to insertably receive a respective one of a pipe and a pipe fitting. A shaft extends lengthwise through the cylinder and the shaft is rotatably coupled to a power tool to rotate the cylinder. A plurality of first bristles is each of the first bristles is coupled to the shaft and each of the first bristles frictionally engages an inside surface of the pipe fitting for de-burring the inside surface of the pipe fitting. A plurality of second bristles is each coupled to the cylinder and each of the second bristles frictionally engages an outside surface of the pipe to de-burr the outside surface of the pipe.

Embodiments of apparatus for reusable drinking straw cleaning include a flexible central brush and a plurality of external brushes supported by a hand-held handle. The flexible central brush is passed one end of a drinking straw and the drinking straw is drawn down into concentrically disposed external brushes. The drinking straw is withdrawn, reversed and the process is repeated. A handle central bore provides external brush pressure onto the straw when it has been drawn into contact with the external brushes. After both ends of the reusable drinking straw are cleaned, the reusable drinking straw is withdrawn from the assembly and placed in a sterilizing solution or dishwasher, and dried. The flexible central brush is replaced without disassembly of the apparatus. Embodiments provide a support stand to receive and hold the assembly in a vertical position from the bottom of a wash sink.

A swab device for cleaning the barrel of a paintball gun has a first shaft, a second shaft and a flexible connector overmolded over ends of the first and second shafts to fixedly couple the flexible connector to the first and second shafts. Absorbent material can be disposed over the first and second rods. The flexible connector can be made of rubber or silicone. The flexible connector is configured to flex and to automatically return to an original linear orientation after the flexible connector has been flexed. The flexible connector can have one or more openings on a surface thereof that facilitate flexion of the flexible connector.

A cleaning assembly for elongated articles includes a housing. A channel extends from a top to a bottom of the housing. A plurality of holes is positioned in the housing and extends annularly around an inner perimeter of the housing. Each hole extends to an interior space of the housing. A pipe, which is coupled to and extends from an outer perimeter of the housing, is in fluidic communication with the interior space. A hose connector that is coupled to the pipe distal from the housing is configured to couple the pipe to a hose. A reservoir is coupled to the pipe proximate to the housing. A tube extends between the reservoir and the pipe so that a cleaning agent in the reservoir is positioned to enter the pipe. Water from the hose and the cleaning agent exit the holes under pressure to clean an article positioned in the channel.

A bug zapper coil cleaner including a brush element that is non-conductive. At least one handle is attached to the brush element. The at least one handle member is configured to move the brush from the outside of the housing on a bug zapper. The at least one handle has an elongated attachment member protruding from one end. Further, there is a clasp member connected to the brush element. The clasp member is a magnetic clasp. The clasp will hold the bug zapper coil cleaner at the top of the bug zapper between uses.

Foldable drinking straws, cleaning elements, and related storage cases are disclosed. In accordance with a first example, a system for drinking liquids includes a storage case, a reusable drinking straw, and a cleaning element. The storage case has a lid and a base defining an internal cavity that includes a straw storing area and a cleaning element storing area. The reusable drinking straw includes a flexible tube having a passageway, a proximal end, and a distal end. The reusable drinking straw is configured to move from a folded configuration to an extended configuration based on an elasticity of the flexible tube. The cleaning element includes a brush and being disposable within the cleaning element storing area and adapted to clean the passageway of the flexible tube.

A flexible composite torsion shaft for attachment to a drive shaft includes an elongated core element having a circular cross section. A reinforcement comprising at least one polymer layer and multiple layers of reinforcing-fiber wound around the core element inside the at least one polymer layer. Each reinforcing-fiber layer is wound around the core element at a winding angle in a range of 40 to the hoop winding angle, depending on a width of a reinforcing-fiber being wound, relative to a longitudinal direction of the core element. At least one reinforcing-fiber-layer is wound at an opposite angle from another reinforcing-fiber layer inside the at least one polymer layer. The winding angle increases as an average layer diameter of reinforcing-fiber insider the at least one polymer layer increases.
