Embodiments of the present invention include a hand air pump handle assembly and a hand air pump, including a pressure gauge elastically attached thereto. The hand air pump handle assembly comprises a handle shell that defines an accommodating space for placement of the pressure gauge. The accommodating space is provided with an air vent for connecting the accommodating space to an inflatable body, such as an inflatable mattress. The pressure gauge measures an internal air pressure for the inflatable body via the air vent and is connected to the handle shell with an elastic connector. The elastic connector can elastically deform to prevent the pressure gauge from being damaged or broken under external forces such as an impact.

Hand air pump handle assembly and hand air pump

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.
