An air pump is delineated for an inflatable product that can be selectively connected thereto. The inflatable product includes a shell located on a side wall. The shell includes an internal chamber for selective placement of the air pump and an air valve for selective communication with the air pump. When the air pump is located in the internal chamber it can be moved to switch between a first position and a second position. The air pump includes an air inlet and an air outlet such that the air inlet is in communication with the air valve in the first position to deflate the inflatable product and the air outlet is in communication with the air valve in the second position to inflate the inflatable product. The air pump can also be used externally via manual connection between the air inlet or the air outlet and other inflatable products.

A high and low-pressure integrated air pump includes a single housing including an air inlet and an air outlet. A high-pressure pump is disposed within the housing and in fluid communication with the air inlet, and uses a first outlet passage to discharge to the air outlet. A low-pressure pump is also disposed within the housing and in fluid communication with the air inlet, and uses a second outlet passage to discharge to the air outlet.

A dual-shaft built-in pump includes a main body, provided with an air inlet and an air outlet; a motor cover, provided with an accommodating cavity having an air inflation vent and an air deflation vent; two valve bodies; a first fan blade, located between the air inflation vent and the air inlet; a second fan blade, located between the air deflation vent and the air outlet; a dual-shaft motor, configured in the accommodating cavity and having an output shaft connected with the first fan blade and the second fan blade; and a rotating member, rotatably provided on the main body and configured to drive either of the two valve bodies thereby opening the air inlet or the air outlet. The pump has simple structure, convenient fabrication and low cost.

A multichannel air assembly (1000) for use with inflatable products with multiple inflatable chambers (C). Specifically, said multi-channel air assembly (1000) may be used to selectively inflate or deflate one or more chambers (C) of an inflatable product to varying pressures.

The present disclosure provides an air pump device, including a housing; a high-pressure air pump, a low-pressure air pump and a public pipeline are arranged in the shell; the high-pressure air pump is a reciprocating air pump, and includes a motor, a piston tube and a piston; the piston is arranged in the piston tube; the motor is used for driving the piston to move in the piston tube; an output shaft of the motor is perpendicular to an axial direction of the piston tube; an air outlet end of the piston tube is connected with the public pipeline, and the piston tube and the public pipeline are parallel or located on the same straight line; the low-pressure air pump is a blowing-type air pump, and includes a shell and a fan assembly.

A compressor includes a housing. An impeller is located within the housing and rotatable about an impeller axis in a first rotational direction. A rotor section is rotatable about the impeller axis in a second rotational direction opposite the first rotational direction.

An air pump with automatic stop of inflation and deflation includes a housing provided with a first air inlet/outlet and a second air inlet/outlet. The inside of the housing is provided with a knob mechanism, an inflation and deflation linkage and an air channel switching mechanism which is connected to the product to be inflated or deflated through the second air inlet/outlet. The inflation and deflation linkage controls the air channel switching mechanism to be operatively connected to the knob mechanism which controls the displacement of the air channel switching mechanism so as to be communicated with the product to achieve inflation or deflation or not to be communicated with the product to achieve automatic stop of inflation or deflation.
