A clutch device (400) for an upright vacuum cleaner and an upright vacuum cleaner (1) having the same are provided, in which the clutch device (400) is disposed between an electric motor assembly (200) and a machine body assembly (300) of the upright vacuum cleaner (1), and the electric motor assembly (200) includes an electric motor housing (21) and an electric motor (22). The clutch device (400) includes: a sliding track (41d) driven (300) to move by the machine body assembly; a toggling tongue (42d) fixed to the electric motor (22) and rotatable with respect to the electric motor housing (21); and a lever member (43d) having a second end of the lever member (43d) slidably fitted to the sliding track (41d) and a first end fitted with an end of the toggling tongue (42d). When the machine body assembly (300) drives the sliding track (41d) to move, the sliding track (41d) drives the lever member (43d) to rotate, and when the lever member (43d) rotates, the toggling tongue (42d) is stirred to make the electric motor (22) rotate with respect to the electric motor housing (21).

The present invention discloses a reciprocating hair removal device for floor cleaning, comprising a roller brush, a first driving structure for rotating the a roller brush, a sliding rail parallel to the roller brush and a sliding block connected to the sliding rail; wherein the surface of the rolling brush is formed with two spiral grooves opposite to each other, the head ends of the two spiral grooves are connected, and the tail ends of them are connected to form a reciprocating spiral groove; wherein the sliding block is provided with a hair removal knife extending from one end to the reciprocating spiral groove; when the roller brush rotates, the hair removal knife reciprocates along the reciprocating spiral groove with respect to the roller brush. Therefore, the present invention can automatically remove foreign matter such as hair entangled on the roller brush during the brush cleaning operation.

An upright vacuum cleaner includes a cleaning head for removing debris from a floor, a debris tube connected to the cleaning head for receiving the debris, and a steering handle connected to the debris tube. The upright vacuum cleaner also includes a hinge connecting the debris tube to the cleaning head such that the debris tube rotates relative to the cleaning head. The upright vacuum cleaner further includes braces to support the debris tube as the debris tube rotates relative to the cleaning head. The braces are disposed on opposite sides of the debris tube. Each brace includes a bearing connected to the cleaning head to allow the brace to rotate relative to the cleaning head.

The disclosure is directed to novel predictive methods and personalized therapies for treating asthma. Specifically, this disclosure relates to methods of treating a patient having asthma by selectively administering an IL-13 antagonist, on the basis of that patient being genetically predisposed to have a favorable response to treatment with the IL-13 antagonist. Also disclosed herein are transmittable forms of information, diagnostic methods, and kits useful in predicting the likelihood that a patient having asthma will respond to treatment with an IL-13 antagonist.

A drive unit with a cleaning module for cleaning an inventory system includes a frame, a drive module, a blower module, and at least one cleaning module mounted to the frame. The drive module includes at least two drive wheels that can move the unit, and the blower module can generate negative pressure in a debris container for applying to one or more cleaning modules. A first cleaning module includes a rotating brush and spans a cleaning path at least as wide as the drive wheels of the drive module as the drive unit with a cleaning module operates. Some cleaning-enabled drive units can include a bifurcation of the first cleaning module to avoid damaging fiducial markings in the inventory system. Such units include a second cleaning module with a stationary brush positioned in line with the bifurcation to clean the fiducial markings along the cleaning path without causing damage.

A cleaner head for a vacuum cleaning appliance includes a main body, a front agitator and a rear agitator, each agitator being rotatable relative to the main body, a mechanism for rotating the front agitator and the rear agitator, and a surface agitating edge located between the front agitator and the rear agitator.

A remote access duster with a body, a flexible duster cord loop that is configured to be propelled such that part of the loop moves outward from the body while another part moves inward toward the body, and a vacuum source that is configured to draw air over the cord.

An upright vacuum cleaner (1) includes: a brushroll assembly (100) including a brushroll casing (12) and a brushroll (11), the brushroll casing (12) defining a brushroll air-suction channel (122) therein; a motor assembly (200) including a motor housing (21) and a motor (22), the motor housing (21) having an air exhaust hole (213), a dirty air outlet (211) and a clean air inlet (212) and defining a motor air-suction channel (216) and a motor air-exhaust channel; and a body assembly (300) including a body (31) and a dirt cup (37) mounted to the body (31), the dirt cup (37) having a separating chamber (371) communicating with the dirty air outlet (211) and the clean air inlet (212) respectively.

A surface cleaning apparatus is provided with a primary fluid distributor and an auxiliary fluid distributor. Each distributor can have a separate and independent flow control actuator. The flow control actuator for the auxiliary fluid distributor is operably coupled with a push-push flow control mechanism, where push-push flow control mechanism has a push on/push off configuration such that pushing the auxiliary flow control actuator once starts fluid flow from the auxiliary fluid distributor and subsequently pushing the auxiliary flow control actuator again stops fluid flow from the auxiliary fluid distributor.

A brushroll for a surface cleaning apparatus includes a brush dowel defining an axis and having opposing bristle supports and a shroud surface between the opposing bristle supports, and a plurality of bristles protruding from the bristle supports. The shroud surface includes opposing convex curved surfaces extending between the bristle supports which intersect the shroud surface at outside corners.
