Abstract

The invention discloses an air pump which comprises a shell, an air valve and an air blasting device. The shell is provided with an accommodating cavity, a first air port and a second air port, wherein the air blasting device is pivoted in the accommodating cavity; the lower end of the air blasting device is connected with the air valve which comprises a rotary shell, a motor, an impeller and an air chamber; a first air guide groove and a second air guide groove are arranged at the lower end of the air blasting device; the upper ends of the first air guide groove and the second air guide groove are respectively communicated with an air inlet end and an air outlet end of the impeller; the lower ends of the first air guide groove and the second air guide groove are alternately communicated with the second air port; and a drive positioning mechanism is arranged between the shell and the rotary shell, and the drive positioning mechanism comprises a plurality of limiting grooves at different heights, a pushing slope surface positioned between two adjacent limiting grooves, a convex column and an elastic element. Therefore, when being rotated, the air blasting device can switch the first air guide groove and the second air guide groove and enable the first air guide groove and the second air guide groove to be alternately communicated with the second air port, and the second air port is opened or closed at the same time, therefore, the operation is convenient, and the structure is simple and compact.

Description

technical field [0001] The invention relates to the technology in the field of inflatable products, in particular to an air pump with simple structure and quick and convenient switching between inflating and exhausting. Background technique [0002] The air pump is a key component of various inflatable products (such as inflatable mattresses, inflatable trampoline, inflatable sofas and large inflatable toys). It is installed on the inner side of the soft bladder of the inflatable products. Perform operations such as rapid inflation, pressure maintenance and rapid deflation to realize the functions of inflatable products that are inflated and unfolded for normal use, and deflated to reduce the volume of the space for storage. [0003] At present, the structures of air pumps for inflatable products seen on the market mainly include a housing, a motor, an impeller and an air valve arranged in the housing. An air hole and an air groove are respectively arranged on the side surf...
