A hair care appliance is provided. The hair care appliance includes a handle and a body coupled to the handle via a rotational hinge joint. The body can be movable via the rotational hinge joint between a straight configuration in which the body is aligned with a longitudinal axis of the handle and a bent configuration in which the body extends along an axis transverse to the longitudinal axis of the handle. A fluid flow path extends between an inlet in the handle and an outlet in the body. The hair care appliance can be operated with minimal loss of fluid flow in either the straight configuration and the bent configuration. The hair care appliance includes a fan assembly in the handle and a heater assembly in the body that are positioned to create a balanced center of mass of the hair care appliance when operated by a user.

The present invention relates to a portable power-driven pipe cleaning device designed for cleaning cylindrical materials, such as pipe ends, in preparation for soldering or brazing. The device comprises a cylindrical brush housed within a plastic housing, a shaft configured for attachment to a power drill, and a metal torque plate positioned inside or outside the housing. The torque plate features locking mechanisms that prevent relative rotation between the shaft and housing, ensuring reliable torque transfer. The torque plate's locking points are positioned at least 6.1 millimeters from the shaft axis, distributing stress and improving the housing's durability. The modular design allows for replaceable brushes and torque plates, accommodating various cleaning tasks. Optional features include protective coatings, gaskets, and venting to enhance performance and longevity. Combining durability, cost efficiency, and versatility, this invention overcomes the limitations of conventional designs, providing an effective and reliable solution for industrial and consumer applications.

A method for cleaning solar panels includes activating an LED light to illuminate a solar panel surface with a source light, evaluating the solar panel for accumulated debris with an optical sensor, determining the presence of accumulated debris, simultaneously activating a motor to power a brush to dislodge the accumulated debris from the solar panel surface and activating an air compressor to provide compressed air to blow away the accumulated debris.

A tube cleaning apparatus has a handheld brush positioner and a control system for controlling operation of a drive unit, wherein the control system is operable to provide current to a drive motor to cause the drive motor to operate the drive unit to extend or retract a flexible shaft, sleeve and brush; and to receive a stop signal from a stop sensor to terminate retraction thereof.

A reciprocating barbecue grill electric cleaning brush is provided. Which includes a main engine and a reciprocating cleaning mechanism. An inner side of the main engine is provided with a driving device, and the driving device has an output end; the reciprocating cleaning mechanism is detachably provided on one side of the main engine. An input end of the reciprocating cleaning mechanism is connected to the output end of the driving device to control a brush head located at a bottom of the reciprocating cleaning mechanism to make high-speed reciprocating motion parallel to a surface of the barbecue grill. This electric brush can efficiently clean corners and crevices by transforming the motor rotation form into a back-and-forth brushing form that simulates manual brushing. This electric brush includes a splash guard and uses auxiliary wheels to assist in movement and press the frame, thereby greatly improving brushing efficiency.

The present embodiment comprises a driving wheel; casters disposed around the drive wheel; and sensors for sensing foreign substances on the surface of the casters; brushes for removing the foreign substances from the surface of the casters; and brush movers that move the brushes to contact positions contacting the casters or separation positions spaced apart from the casters, according to values sensed by the sensors.

A haircare apparatus has a plurality of capacitive sensors, each capacitive sensor configured to provide a capacitance reading indicative of hair proximal to the haircare apparatus. The haircare apparatus has a moisture estimation module configured to estimate, based on capacitance readings of the plurality of capacitive sensors, a moisture level of the hair proximal to the haircare apparatus.
