Preferably, the isolation device 2 includes one isolation component, and the number of the isolation components may be one, or may be two or more. The specific structure of the isolation assembly is varied. For example, the isolation assembly comprises two partition plates which are connected in a rotating mode, when the partition plates are placed horizontally, the partition plates are in an isolation state, and when the partition plates rotate to a set angle from the horizontal position, the partition plates are in a conduction state. Or the isolation assembly only comprises a rotatable isolation plate, when the isolation plate is horizontally placed, the isolation plate is in an isolation state, and when the isolation plate rotates to a set angle from the horizontal position, the isolation plate is in a conduction state.
