The mouthpiece for an aerosol-generating article comprises a housing with an inlet end, configured to allow an aerosol to flow into the mouthpiece, an outlet end, configured to allow the aerosol to flow out of the mouthpiece, and an aerosol flow path extending between the inlet and the outlet end. The mouthpiece is formed such that the flow direction of the aerosol is reversed at least once between the inlet and the outlet end. The invention also concerns an aerosol-generating system comprising an aerosol-generating device and the mouthpiece, as well as a method for assembling the mouthpiece.

A hookah including a high-frequency heating assembly and a hookah assembly. The high-frequency heating assembly is detachably disposed on the hookah assembly. The hookah assembly includes a heating cup configured to accommodate a tobacco material and a glass tube assembly configured to accommodate water. The lower part of the heating cup is disposed in the opening of a first tube body of the glass tube assembly. The high-frequency heating assembly includes a magnetic induction coil, and the upper part of the heating cup is disposed in the magnetic induction coil. In a power-on state, when an alternating current passes through the magnetic induction coil, a magnetic induction effect is generated, so that the heating cup is heated up and the smoke material is atomized to produce smoke; the smoke enters into the glass tube assembly and is filtered by water and inhaled by a user.
