The utility model provides a suction nozzle assembly, an atomizer and an electronic atomization device. The suction nozzle assembly comprises: a suction nozzle seat body having an air guide channel; the air guide channel is communicated with an air outlet channel of the atomizer; and the suction nozzle cover body and the suction nozzle seat body are in sliding connection through an elastic piece in the direction of the rotating shaft. The suction nozzle cover body is provided with a first limiting mechanism; the suction nozzle seat body is provided with a second limiting mechanism; when the suction nozzle cover body is located at the first position relative to the suction nozzle seat body, the air guide channel is not communicated with the outside through the suction nozzle cover body; the elastic piece drives the suction nozzle cover body to slide relative to the suction nozzle base body in the direction of the rotating shaft, locking of the suction nozzle cover body and the suction nozzle base body is achieved through the first limiting mechanism and the second limiting mechanism, and unlocking of the suction nozzle cover body and the suction nozzle base body is achieved when the suction nozzle cover body and the suction nozzle base body reversely slide in the direction of the rotating shaft. And when the suction nozzle cover body is located at the second position relative to the suction nozzle seat body, the air guide channel is communicated with the outside through the suction nozzle cover body. Therefore, the risk that the atomizing medium volatilizes and is polluted can be reduced; and the suction nozzle cover body is not easy to lose and convenient to use.

An air-floating motion platform includes: a base, a linear motion drive device, an air-floating device, and an air supply device. The air-floating device is movably supported on the base, and the air supply device is disposed on the base, passing through the air-floating device. The linear motion drive device drives the air-floating device to reciprocate linearly on the support surface of the base. The air supply device is in an open state facing the location of the air-floating device, supplying air to the air-floating device, forming an air film between the air-floating device and the support surface of the base, causing the air-floating device to suspend on the support surface of the base. The air supply device gradually closes as it deviates from and eventually leaves the air-floating device. Magnetic preloading increases the stiffness of the air film, and the mechanical switching function formed by the cooperation of the air-floating device and the air supply device achieves air supply without air pipe disturbance during movement, reducing air consumption compared to stationary guide rail air-floating. The air-floating motion platform provided by this invention effectively solves the problems of high air consumption, low air film stiffness, and air pipe disturbance in existing air-floating motion platforms.
