The cooling and heating bladeless fan comprises an air inlet base, a fan motor assembly, a front air inlet, an air outlet shell and an air outlet, a movable air deflector is arranged on the left side of the air outlet, a fixed air deflector is arranged on the right side of the air outlet, and the movable air deflector and the fixed air deflector are matched to form a horn shape; a front movable cover plate capable of sliding up and down is arranged on the front side of the air inlet base, and a transmission device is arranged between the front movable cover plate and the movable air deflector; when the front movable cover plate slides upwards to close the front air inlet, the movable air guide plate can be driven to rotate through the transmission device to be matched with the fixed air guide plate to close the air outlet. The air inlet and the air outlet are closed when the fan is idle, dust is effectively prevented, and the service life of internal elements is prolonged; the two air ports can be synchronously closed by sliding the cover plate, operation is easy and convenient, and user experience is improved; the trumpet-shaped air guide structure can optimize air flow guide, and air supply is more concentrated and smoother.
