The present disclosure relates to electronically-controlled air assemblies having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, the present disclosure relates to air assemblies where the configuration of the air assembly can be changed by a user operating a directional control valve to inflate, deflate, or close an inflatable product. The air assembly may also maintain a predetermined air pressure value within the inflatable product.

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.

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.

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.

Air assemblies (1000,2000,3000,4000,5000) having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, air assemblies (1000,2000,3000,4000,5000) can be changed manually by a user by operating a directional control valve (1033,2043,3033,4033,5001) to inflate, deflate, or close the inflatable product. The directional control valve (1033,2043,3033,4033,5001) may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.

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.

A single-knob air pump includes a housing provided with a first air inlet/outlet and a second air inlet/outlet; an air extracting mechanism arranged in the housing; fan blades of the air extracting mechanism arranged in a fan blade chamber provided with an air inlet and an air outlet; an air channel switching mechanism arranged near the fan blade chamber and provided with an air inlet and an air outlet; the air channel switching mechanism operatively connected to a knob mechanism which can control the displacement of the air channel switching mechanism; the second air inlet/outlet provided with an air valve mechanism capable of closing or opening the second air inlet/outlet; and an ejector rod mechanism capable of closing or opening the second air inlet/outlet through the air valve mechanism under the action of the air channel switching mechanism arranged between the air valve mechanism and the air channel switching mechanism.

A multifunctional air pump is disclosed including an air pump assembly, a control module, and a remote user input for inflating and deflating an inflatable product. The air pump may be operated remotely for convenience. The air pump may also operate automatically to maintain the pressure of the inflatable product.

A pump assembly is provided for use with an inflatable product. The inflatable product has a chamber having an air inlet and an air outlet. The pump assembly has a pump unit that is positioned inside the chamber for inflating and deflating the chamber, the pump unit having a motor that is operatively coupled to a first blower and a second blower, with the first blower is fluidly coupled to the air inlet and the second blower is fluidly coupled to the air outlet. The chamber is inflated by intake of air through the air inlet to the first blower and then into the chamber, and the chamber is deflated by drawing air from the chamber to the second blower and then out of the chamber through the air outlet.

A smart air pump comprises a housing defining an accommodating chamber. A main air pump is located in the accommodating chamber for inflating or discharging air from an inflatable body. The main air pump includes a cover defining an inlet and an outlet port. The cover divides the accommodating chamber into an impeller and a driving chamber. An air replenishing pump is located in the accommodating chamber. A driving switch, located in the driving chamber, connects to the main air pump. A central control unit electrically connects to the main air pump, the air replenishing pump, and the driving switch. The central control unit comprises a time control module configured to initiate periodic replenishment of air to the inflatable body. The time control module has a setting module and a counting module. An inflatable device including a smart air pump is also disclosed herein.
