A first venting hole and a second venting hole are respectively provided on internal walls at two sections of the internal pipe above and below the diaphragm. An external sleeve is provided outside the internal pipe. The lower end of the external sleeve is fixedly connected to the pump casing. The lower end of the external sleeve correspondingly communicates with the air valve. A wall of the external sleeve is provided with an air outlet communicating with an air inlet of the air pump and an air inlet communicating with an air outlet of the air pump. An upper end of the connection pipe is connected to and communicated with the switch hand-wheel, and the lower end of the connection pipe is muff-coupled with the upper end of the internal pipe. The diaphragm of the internal pipe contacts a valve rod of the air valve such that the valve is opened by an applied external force and the diaphragm and the value are moved together.

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.

A thrust generating apparatus for controlling an attitude of a movable body includes an outer shell body, a first inner shell body and a second inner shell body, a first fan rotating body and a second fan rotating body, an intermediate shell body, and a driving unit. A outer surface of the intermediate shell body has a shape such that an air flow sent from an opening end inside of any one of the first inner shell body and the second inner shell body is accommodated and flowed out to an outer flow path . When the first fan rotating body is rotated, the air flow suctioned from the outside in the axial direction of the first inner shell body passes through the outer flow path defined by the second inner shell body to be jetted from a second opening end of the outer shell body.

A bidirectional air pump, belonging to the technical field of air pump, includes a housing and a pump body, wherein an accommodating groove is defined on a side of the housing, the pump body is accommodated in the accommodating groove, a first air hole is defined on a bottom of the accommodating groove, the pump body comprises a casing and a wind assembly, the casing is hollowed-out, the wind assembly is arranged in the casing, an air inlet and an air outlet are respectively defined at two ends of the casing, and a position of the first air hole is aligned with a position of the air inlet and a position of the air outlet.

An inflating module adapted to an inflatable object includes a pressure controlling assembly configured to monitor air pressure in the inflatable object after the inflatable body has been inflated and a supplemental air pressure providing device. The pressure controlling assembly is configured to automatically activate the supplemental air pressure providing device when the air pressure inside the inflatable object decreases below a predetermined threshold after inflation, and to control the supplemental air pressure providing device to provide supplemental air pressure to the inflatable object so as to maintain the air pressure of the inflatable object within a predetermined range.

An inflating pump includes an enclosure having an exterior shell and an enclosing wall located in the exterior shell and enclosing an airflow passage, and a discharge space formed between the exterior shell and the enclosing wall; an air blower connected to the enclosing wall; two air delivery pipes; and an airflow switching mechanism including a fixed seat having a plurality of chambers separately communicable with the airflow passage, the discharge space, the air blower and the two air delivery pipe, and a turnable member being turnable relative to the fixed seat for some of the chambers to communicate with one another to allow airflow pushed out from the air blower to flow through the airflow passage, the discharge space or the two air delivery pipes. Therefore, the inflating pump can inflate and deflate an inflatable air bed when the air blower constantly produces airflow in the same direction.

An air leakage prevention adjusting structure of a mechanical pump is provided. The adjusting structure may be applied to a multi-channel pump. The multi-channel pump may comprise a body, an air pump assembly and a channel switching structure which are arranged in the body, and a panel matched on the body. The adjusting structure may be matched on the panel and may comprise a channel selection knob, a turntable and a power switch. The channel selection knob may be rotatably arranged on the panel. The turntable may be arranged in the body. The upper end of the turntable may be connected with the channel selection knob, and the lower end of the turntable may be matched with the channel switching assembly. A convex edge and a notch may be arranged on the turntable. A button for controlling the on-off of a power supply is arranged on the power switch, and is selectively matched with the convex edge and the notch of the turntable. A user only needs to operate the channel selection knob to control the two functions, so that the operation of the user is facilitated, and the condition of air leakage of the inflatable product caused by omission of the operation of the user is effectively avoided.

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.
