A suction cleaner and an operation method thereof are provided. The suction cleaner includes a housing, a holding part, an impeller module, at least one sensing device, and a controller. An end of the housing has a dust-suction opening. The impeller module is located inside the housing, and a channel is located between the impeller module and the dust-suction opening. The controller is electrically connected to the sensing device to drive and adjust the rotation rate and the suction force of the impeller module, and thus the power consumption of the suction cleaner can be reduced.

The present invention relates to an air cleaner for the removal of pollutants from an air flow by a filter module, the filter module of which includes at least one permeable filter layer for the accumulation of pollutants on the filter layer. According to the invention, a bypass channel will be provided and established such that part of the unfiltered air flow may bypass any filter layer. Surprisingly, such a bypass channel does hardly compromise the cleaning effect of the filter module, at least as long as the filter layer has not yet been clogged with pollutants since in this case the biggest part of the air flow will take the major path through the filter layer due to lack of resistance. Only if the filter layer is clogged and if resistance for the air flow increases, air will obviously flow through the mentioned bypass channel.

A hand dryer device cooperated with an airflow driver includes a first housing, a second housing, and an airflow driving unit. The first housing has a first body and a first extension portion. The second housing has a second body and a second extension portion. The second body is connected to the first body for defining an accommodating space, and the first and second extension portions together form a concave annular structure having an extension space. The airflow driving unit includes a sensor, a control module and an airflow guiding structure. The sensor is disposed on the outer surface of the first housing and / or the second housing. The sensor detects and outputs a sensing signal. The control module receives the sensing signal and outputs a control signal. The airflow guiding structure is disposed adjacent to an air outlet and extends to the extension space.

The invention provides an energy-saving natural gas burner capable of preventing clotted slag in a furnace. The natural gas burner comprises a mixing chamber, a combustion chamber, a gas inlet, a combustion-supporting air inlet and an igniter, wherein the gas inlet and the combustion-supporting air inlet communicate with the mixing chamber, and the igniter is arranged corresponding to the combustion chamber; the outer side of the combustion chamber is provided with an interlayer with the upper end being opened; an opening of the interlayer is formed surrounding an outlet of the combustion chamber so that an air partition surrounding flames can be formed; air deflectors / air guiding columns are installed at the opening of the interlayer, all the air deflectors / air guiding columns are obliquely arranged and parallel to one another so that the air partition can be in a spiral shape; and the lower portion of the interlayer is provided with an air inlet. The flames are limited through air flow of the interlayer, so that the flames are prevented from fleeing outwards, and the situation that the clotted slag in the furnace occurs due to the fact that the flames make contact with the furnace wall of the combustion furnace is avoided; and meanwhile, the flames are collected under the action of the spiral air partition to form a fire pillar, a combustion area is concentrated, the precision is higher, and ore sand expanding is facilitated.
