Magnetic inflation device and inflating and deflating method thereof

A magnetic inflation device, comprising:

• an inflating base, comprising an inflating base main body, a valve core, an elastic member and a first magnetic member, wherein the inflating base main body defines a valve cavity therein, and the inflating base main body defines a first gas channel and a second gas channel connected to the valve cavity;
• the valve core and the elastic member are mounted in the valve cavity, and a lower end of the valve core extends into the first gas channel;
• the elastic member is configured to apply elastic force to the valve core to force the valve core to press downwards to close the first gas channel;
• and the first magnetic member is mounted in the inflating base main body;
• and
• an inflating head, comprising an inflating head main body, wherein the inflating head main body is configured to dock or separate from the inflating base main body, the inflating head main body defines a third gas channel cooperating with the first gas channel, an upper end of the third gas channel is configured to lift the lower end of the valve core upwards and force the valve core to move upwards against the elastic force of the elastic member to open the first gas channel;
• and a second magnetic member is mounted in the inflating head main body, the second magnetic member is magnetically matched with the first magnetic member, and magnetic force between the first magnetic member and the second magnetic member is greater than the elastic force applied by the elastic member to the valve core.
