An air purifying system may include a main air purifier placed in an indoor space, a handheld air purifier mounted on the main air purifier, and an air quality sensor IOT device that communicates with the main air purifier. The air quality sensor IOT device may be fixed in an outdoor space adjacent to the indoor space, or may be carried by a user to measure air quality data while the user travels. The main air purifier may automatically operate based on air quality data received from the air quality sensor IOT device.

A hand vacuum cleaner comprises a cyclone comprising a front end having a cyclone air inlet, a rear end having a cyclone air outlet and a cyclone axis of rotation extending between the front end and the rear end of the cyclone. A conical pre-motor filter is positioned rearward of the cyclone. The pre-motor filter has a front end that faces that faces towards the cyclone air outlet. A suction motor is positioned rearward of the pre-motor filter. The suction motor has an inlet end that faces towards a rear end of the pre-motor filter. A handle is provided at the rear end of the hand vacuum cleaner and is positioned rearward of the suction motor. The handle has an energy storage member housing, The cyclone axis of rotation and the suction motor axis of rotation are parallel, and the handle axis extends at an angle to the cyclone axis of rotation and the suction motor axis of rotation.

A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, the housing further including a handle along a handle axis. A suction nozzle is along a suction nozzle axis that extends in a direction from the front end toward the back end. The handheld vacuum further includes a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust. A battery that supplies power to the suction source and the battery is coupled to the housing adjacent an end of the handle. The handle extends between the battery and the cyclonic separator.

A cleaner includes a housing, a body slidably coupled to the housing, a dust container mountable to the housing and detachable from the housing, and a pushing device slidably coupled to the dust container and mountable to the body and detachable from the body.

A cleaner including a cyclone dust collector and a filter has a shortened total length. The cleaner includes a main unit including a suction port, a cyclone unit including a cyclone dust collector having an outlet and a cylinder located rearward from the outlet and having an opening larger than the outlet, and a filter located frontward from the suction port and covering the opening.

The present disclosure provides a valve (123), comprising a channel body (1231) defining a bent channel space, an elastically flexible membrane (1233), which separates a control space (Sc) from a flow space (Sf) in the channel space, a control connection (1232), providing a fluid connection to the control space (Sc), The control space (Sc) is provided at a radially outermost portion (Co) of the channel space, as per a channel bending radius (Ro), such that the membrane (1233) is flexible between an open position, whereby a cross section of the flow space (Sf) is substantially that of the channel, and a closed position, whereby the membrane substantially seals against a radially innermost portion (Ci) of the channel, as per the channel bending radius (Ri). Use of the valve in a separator is disclosed, as well as a separator comprising such valve and a method of cleaning a separator body.
