A flow means with a housing and a fan to generate a fluid flow within a pipe or hose line of an intake monitoring system. The fan can be connected to the pipe or hose line via connecting pieces and can be driven to rotate. The invention creates a flow means which enables the direction of flow to be reversed. Respective blocking means are assigned to the connecting pieces and can be moved from an intake position (PS), in which an intake region of the fan is connected to the respective connecting piece into an exhaust position (PB), in which an exhaust region of the fan is connected to the respective connecting piece so the flow within the pipe or hose line is in a first direction of flow (S1) or in a second direction of flow (S2) as a function of the position (PS, PB) of the blocking means.

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 voltage regulation and speed regulation control circuit (100, 130, 200, 250) of an air pump (102) is provided. The voltage regulation and speed regulation control circuit (100, 130, 200, 250) may comprise a chopper power supply circuit (104, 202), a full bridge rectifier circuit (106, 204) and a switch (108, 212). The switch (108, 212) may be used to switch the chopper power supply circuit (104, 202) or the full bridge rectifier circuit (106, 204) to be connected to the positive and negative input terminals (103, 105) of the air pump (102). The output voltage of the chopper power supply circuit (104, 202) and the output voltage of the full bridge rectifier circuit may be different (106, 204).

An air pump for an inflatable product may include a pressure valve assembly and an inflation-and-deflation control assembly. The inflation-and-deflation control assembly may include a switch assembly operatively coupled to the pressure valve assembly and a pump assembly operatively coupled to the switch assembly. The switch assembly may have a first position and a second position, and the pressure valve assembly may be configured to engage the switch assembly to maintain the switch assembly in the first position or the second position. When the pressure valve assembly detects that a pressure threshold has been reached within the inflatable product, the pressure valve assembly may disengage from the switch assembly.

An air pump for an inflatable product may include an inflation-and-deflation control assembly, a pump assembly, a pressure valve assembly, and a linkage assembly. The pressure valve assembly may detect the pressure inside an inflatable chamber of the inflatable product. Once a pressure threshold is reached within the inflatable chamber, the pressure valve assembly may activate the linkage assembly. The linkage assembly may cause the inflation-and-deflation control assembly to deactivate the air pump and place the air pump in a closed or sealed position.

Provided are an inflatable pump, an inflatable assembly, and an inflatable product, relating to the technical field of inflatable products, wherein the inflatable pump includes an inflatable pump housing, a mounting cavity is provided in the inflatable pump housing, a spacer plate is provided in the mounting cavity, and a first mounting slot and a second mounting slot are provided on an upper top cover; and a control assembly is provided in the first mounting slot, and a handle is rotatably configured in the second mounting slot.

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 rotary inflating and deflating pump includes a housing and a pump core, the housing is provided with a chamber therein, the inner bottom wall of the chamber is provided with a housing hole; the pump core includes a pump shell and a driving member; the pump shell is detachably installed into the pump shell; a pump chamber is provided inside the pump shell, and an inlet hole and an outlet hole are provided on one end of the pump shell near the housing hole and respectively communicated with the pump chamber; the driving member is provided inside the pump chamber and used to drive gas to enter the pump chamber from the inlet hole and then flow out from the outlet hole; by rotating the pump core clockwise or counterclockwise, the pump can be changed to inflate or deflate, which is more convenient to use.

A multi-gear inflation and deflation device for a swimming pool having an air cavity and a water cavity may include an air pump group, a valve body in fluid communication with the air pump group, and a driving component positioned on the valve body. The valve body may include a valve core rotatably received within the valve body, and the driving component may be configured to drive the valve core between an inflation position, a deflation position, an aeration or massaging bubble position, and a sealed position.
