Detailed Description

As shown in fig. 1, the present embodiment includes an air pump 1, a first electromagnetic valve 2, and a second electromagnetic valve 3. The first electromagnetic valve 2 and the second electromagnetic valve 3 are two-position three-way electromagnetic valves of the same type and specification, as shown in fig. 4, the three-way valve includes three air ports, namely a first air port 21, a second air port 22 and a third air port 23, the two positions include two using states, the first air port 21 is communicated with the second air port 22 in the first using state, and the first air port 21 is communicated with the third air port 23 in the second using state. The electromagnetic valve of the embodiment is in a first use state when being electrified, and is in a second use state when being powered off.

The first air port 21 of the first electromagnetic valve 2 is communicated with the air inlet of the air pump 1, and the first air port 21 of the second electromagnetic valve 3 is communicated with the air outlet of the air pump 1. The second air ports 22 of the first electromagnetic valve 2 and the second electromagnetic valve 3 are communicated with the air bag. The third ports 23 of the first solenoid valve 2 and the second solenoid valve 3 are opened to the atmosphere.

During inflation, the first electromagnetic valve 2 is powered off, and the second electromagnetic valve 3 is powered on. The atmosphere enters from the third air port 23 of the first electromagnetic valve 2, passes through the first air port 21 of the first electromagnetic valve 2, enters the air pump 1 from the air inlet of the air pump 1, and the air is conveyed to the first air port 21 of the second electromagnetic valve 3 from the air outlet of the air pump 1 and then enters the air bag through the second air port 22 of the second electromagnetic valve 3 for inflation.
