An electric air pump system includes a housing in fluid communication with an inflatable body, a first valve, a first air pump for inflating and deflating the inflatable body, a second air pump for inflating the inflatable body, an air pressure sensor configured to detect the inner pressure of the inflatable body, and first and second prompting devices. The system also includes a control device electrically coupled to the first and second air pumps, the air pressure sensor, and the first and second prompting devices. The first prompting device outputs a first indication signal when the inner pressure is less than or equal to a first air pressure threshold and the second prompting device outputs a second indication signal when the second air pump inflates the inflatable body.

Electric air pump system

A swimming machine is delineated comprising a water driver for generating a directed flow of water and a housing adapted for receiving the water driver. An adjusting assembly is disposed above the housing and coupled to the housing via an adjustable connector that allows the housing and the adjusting assembly to move relative to each other to set the housing at a desired depth in a pool. A hanging assembly is coupled to the adjusting assembly such that the adjustment assembly can hang on an upper edge of a pool. The swimming machine further includes a supporting assembly independent of the adjusting assembly that is coupled to the housing to move therewith and is disposed below the hanging assembly. The supporting assembly contacts against the inner wall of the pool to support the body.

Swimming machine

An adjustable support for a provided swimming machine includes a movable assembly and a fixed assembly for adjusting the height of the provided swimming machine. The movable assembly is fixedly mounted to the provided swimming machine. The fixed assembly is attached to a pool wall of a provided swimming pool and selectively coupled to the movable assembly. One of the movable assembly or the fixed assembly includes a plurality of engaging portions, and the other of the movable assembly or the fixed assembly includes a limiting member that mates with at least one of the plurality of engaging portions. The movable assembly is switchable between a locked position and an unlocked position. The limiting member fixedly engages at least one of the plurality of engaging portions in the locked position. The limiting member is disengaged from the at least one of the plurality of engaging portion in the unlocked position, thereby providing for the movable assembly to move vertically relative to the fixed assembly.
