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.

The present application proposes a method and a system for constructing a data command frame for remote reservation control, by setting a first byte representing a reserved working time start point, a second byte representing one-time working duration, a third byte representing the reservation status of a whole working cycle, the whole working cycle is divided into several time units, the third byte includes several bits corresponding to several time units, and assigns the value of each bit to determine whether the time units corresponding to each bit is reserved as working time; then combining the first byte, the second byte and the third byte to construct data command frame, and sending the command frames to device to realize remote control. This method enables remote reservation setting on the management of places like spa pools, which is safer and more convenient for spa management staff, and can greatly improve working efficiency and reduce the probability of error.

An inflatable product includes an integrated axial-flow pump which produces a high rate of inflation. The pump includes a cover mounted to a body of the pump and selectively configurable between open and closed positions. In the open position, air is allowed to flow between the inflatable chamber and the ambient air through the pump body. When the cover is closed, the air chamber of the inflatable product is sealed with respect to the ambient air such that air is retained within the inflatable chamber when inflated. A power switch is positioned to be deactivated by the cover when the cover is mounted to the body of the pump, such that replacement of the cover during inflation or deflation of the inflatable product automatically deactivates the pump.

An air pump assembly for an inflatable product may include a housing, a cover coupled to the housing, and a rotatable assembly supported by the housing. The rotatable assembly may include a pump housing having first and second air vents, an impeller positioned within the pump housing, a motor operatively coupled to the impeller, and a rotary disc positioned between the pump housing and a vent hole of the housing. The rotatable assembly may be rotatable to a first position wherein air flows from the first air vent of the pump housing to the second air vent of the pump housing and through the vent hole in the housing into an interior of the inflatable product and a second position wherein air flows from the interior of the inflatable product through the vent hole in the housing into the first air vent and then to the second air vent.

An adjustable attachment structure for a swimming machine is disclosed. The attachment structure is configured to interact with a frame of a pool. A user may interact with a locking switch to transition the attachment structure between a locked and an unlocked state. In the unlocked state, the swimming machine may be rotated about an axis to direct a generated current in a number of directions.

An inflatable product can be inflated to a low pressure by a lower-power but high-volume electric pump, then 'firmed' or fully inflated by an auxiliary pump. The auxiliary pump may be manually powered, such that the overall cost and complexity of the electric and auxiliary pumps are still lower than a high-power electric pump. The low power high volume electric pump can be easily powered by small batteries that will also provide an increased number of inflations compared to traditional high-power pumps for a given battery capacity. Using small batteries allows the pump to be very compact in size. The auxiliary pump may work through an auxiliary air chamber within the primary air chamber and fluidly connected thereto by a check valve. The electric pump may be reversible to provide for both inflation and deflation.
