The floor brush includes a brushroll (11); a motor (22) driving the brushroll (11) to roll via a drive belt (13) that is winded upon a motor shaft (221) of the motor (22) and a central part of the brushroll (11); and a brushroll casing (12) provided outside the brushroll (11), having a dust suction port and defining a brushroll air-suction channel (122) and a drive-belt mounting chamber (123) for mounting the drive belt, in which the brushroll air-suction channel (122) comprises a first air-suction channel (1221) and a second air-suction channel (1222) located at both sides of the drive-belt mounting chamber (123).

A blowing-suction machine includes an engine, a volute, a vent assembly and a vacuum pipe. The engine is installed at an upper end of the volute; the vent assembly is installed at a front end of the volute; an output shaft of the engine in the volute is coupled to a vane; a first shaft of a self-propelled device is coupled to a lower end of the first shaft; both ends of a second shaft of the self-propelled device are coupled to a wheel self-propelled device and a rolling-sweeping-combing device respectively; and the vacuum pipe has an end coupled to the vent assembly and the other end disposed in front of a garbage deposit box. This disclosure features a simple structure and a clever design and provides the self-propelled, automatic sweeping, automatic grass combing, and garbage crushing functions to improve the blowing-suction rate significantly and provide a convenient use.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

A clutch device for an upright vacuum cleaner and an upright vacuum cleaner having the same are provided. The clutch device is disposed between an electric motor assembly and a machine body assembly of the upright vacuum cleaner, the electric motor assembly includes an electric motor housing and an electric motor, the machine body assembly includes a machine body and a bridging member rotatably connected to the electric motor housing. The clutch device includes a slide chute; and a triggering member having a first end provided with a sliding column slidably fitted in the slide chute and a second end provided with a toggling rod configured to stir the electric motor to move. When the bridging member drives the slide chute to move, the sliding column slides along the slide chute to rotate the triggering member. When the triggering member rotates, the toggling rod stirs the electric motor to rotate.

A cleaning apparatus comprising a housing, at least one agitator configured to be rotatably coupled to the housing, a combing unit comprising a plurality of spaced teeth configured to contact the agitator for preventing build up and removing debris, and a switch configured to cause the combing unit to move between an active mode in which the plurality of spaced teeth are configured to contact the agitator for preventing build up and removing debris, and an inactive mode in which the plurality of spaced teeth are configured to not contact the agitator. The switch may be configured to cause the combing unit to rotate about a pivot axis between the active mode and the inactive mode. The switch may be configured to convert linear motion of the switch into the rotational motion of the combing unit about the pivot axis.

An upright vacuum cleaner (1) is provided, including a brushroll assembly (100), a motor assembly (200) and a body assembly (300). The brushroll assembly (200) includes a brushroll casing (12) and a brushroll (11). The motor assembly (200) includes a motor housing (21) and a motor (22), and the motor (22) drives the brushroll (11) to roll via a drive belt (13). The body assembly (300) includes a body (31) and a bridging member (32) mounted to the body (31), and the bridging member (32) is pivotably connected with the motor housing (21) to allow the body (31) to be rotatable between an upright position and an oblique position. When the body (31) is rotated from the upright position to the oblique position, the bridging member (32) pushes the brushroll casing (12) to move in a direction running away from the motor housing (21) so as to tension the drive belt (13).

The present specification relates to an automatic cleaner. The automatic cleaner, according to one aspect, comprises: a casing having an inlet port; a suction device which is installed inside the casing and sucks external foreign substances through the inlet port; a moving device for moving the casing; and a side brush assembly movably installed at the casing, wherein the side brush assembly comprises: a movable member which is provided so as to be movable in the casing and protrudes outside of the casing; a side brush provided so as to be rotatable at the movable member; a hinge shaft for enabling the rotation of the movable member; and an elastic member for supporting the hinge shaft or the movable member.

A vacuum cleaner includes a suction nozzle defining a nozzle inlet, a manual nozzle height adjustment assembly for adjusting the height of the nozzle inlet relative to a surface to be cleaned, and a bleed valve fluidly connected to a working air path of the vacuum cleaner to selectively open to reduce suction at the nozzle inlet. The bleed valve is incorporated with the nozzle height adjustment assembly such that movement of the nozzle height adjustment assembly between different height settings will automatically open or close the bleed valve.

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.

Provided is a floor brush assembly for a vacuum cleaner. The floor brush assembly includes a roller brush component and a driving mechanism. A roller brush body of the roller brush component is rotatably mounted in a sleeve. The roller brush body is provided with bristles arranged in an elongated shape to form a bristle portion. The sleeve of the roller brush component has an avoidance opening of an elongated shape, and the bristle portion and the avoidance opening are arranged to directly face towards each other in a radial direction of the roller brush body. A first driving member of the driving mechanism is configured to drive the roller brush body to rotate, and a second driving member is configured to drive the sleeve to rotate. The first driving member and the second driving member are eccentrically arranged to allow the bristle portion to be selectively extended or retracted through the avoidance opening.
