Abstract: The present disclosure provides an inflatable doll, which includes a body having a first air inlet, a plurality of expandable members received in the body and connected with the body, and an air blower assembly. Each expandable member defines a second air inlet. The air blower assembly includes a first air blower arranged adjacent to the first air inlet and a plurality of second air blowers received in the body and communicated with second air inlets. The first air blower is configured to introduce air into the body to inflate the body and the expandable members. Each second air blower is configured to direct air out of one corresponding expandable member, so that the expandable members are deformed to move the body.

Abstract: Provided is an inflatable doll, including a body, at least one airbag and an air blower assembly. The body includes a primary portion having a first air inlet, and a secondary portion. Each airbag defines a second air inlet, the airbag is connected with the primary portion and/or the secondary portion. The air blower assembly includes a first air blower adjacent to the first air inlet, and at least one second air blower at least partially received in the second air inlet. The first air blower is configured to inflate the primary portion, the secondary portion and the airbag. The at least one second air blower is configured to deflate the primary portion and/or the secondary portion. The second air blower is intermittently actuated, so that the primary portion and/or the secondary portion is intermittently inflated or deflated, for bringing the primary portion and/or the secondary portion to move.

Abstract: The utility model discloses an inflation device of a party inflatable suit, comprising a blower and a battery box connected therewith, and a mounting cover for fixing the blower at an inflation port of the inflatable suit, wherein mutually engaged gears are arranged on the inner periphery of the mounting cover and the outer periphery of a hollow cylindrical portion at the top of an upper shell of the blower, and the blower is fixed at the inflation port of the inflatable suit by gear engagement. The party inflatable suit is inflated by the inflation device connected at the inflation port thereof, and is firm in connection and convenient in use.

Abstract: A system and method for modulating capacity of a scroll compressor having a motor includes determining a target capacity of the scroll compressor, operating the motor at a first speed when the target capacity is within a first predetermined capacity range and at a second speed when the target capacity is within a second predetermined capacity range, determining a pulse width modulation cyclic ratio based on the target capacity and the first or second speed, and periodically separating intermeshing scroll members of the compressor according to the pulse width modulation cyclic ratio to modulate the capacity of the scroll compressor.
