Abstract: A built-in air pump with rapid inflation and deflation for an inflatable product includes a first channel, a second channel and a centrifugal fan. A first air hole and a third air hole are formed in the first channel. A second air hole and a fourth air hole are formed in the second channel. The suction end of the centrifugal fan is abutted against the first channel, and the exhaust end of the centrifugal fan is abutted against the second channel. When in inflation, the first air hole and the second air hole are communicated with the outside of the inflatable product, and the third air hole and the fourth air hole are communicated with an inner cavity of the inflatable product.

Abstract: A dual-chamber air bed includes an air pump, a bed body air chamber and peripheral air chambers. The air bed is enclosed by a top surface, a bottom surface and a side wall. An upper supplementary-material encircling piece is provided between the top surface and the side wall; a lower supplementary-material encircling piece is provided between the bottom surface and the side wall. The peripheral air chambers are enclosed by the top surface, the side wall and the upper supplementary-material encircling piece, and by the bottom surface, the side wall and the lower supplementary-material encircling piece. The bed body air chamber is enclosed by the top surface, the bottom surface, the side wall, the upper supplementary-material encircling piece, and the lower supplementary-material encircling piece.

Abstract: The present invention discloses an air bed including a mattress body formed by a top surface, a bottom surface and a side wall. The mattress body is provided with at least two layers of side walls being an inner side wall and an outer side wall respectively. The inside of the inner side wall forms a bed air chamber of the mattress body. A side wall air chamber of the mattress body is formed between the inner side wall and the outer side wall. The inside of the side wall air chamber between the inner side wall and the outer side wall is connected with a plurality of side wall drawstrings. The side wall drawstrings form a bed edge of the mattress body with the inner side wall, the outer side wall, and the side wall top surface/side wall bottom surface respectively.

Abstract: 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.

Abstract: 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.
