Abstract: A split-type microporous direct-injection aromatherapy machine comprises a base, a shell and an atomizing module arranged between the base and the shell, wherein a connecting mechanism is arranged on the base, and the shell and the base are connected with each other through the connecting mechanism; a slot is arranged on the base, and the atomizing module is detachably inserted into the slot; the atomizing module is electrically connected with the base, and the shell can cover the lower part of the atomizing module. The atomizing module comprises a liquid storage bottle and a liquid guide tube, wherein the liquid guide tube can be inserted into the slot, and the liquid guide tube comprises a connecting part and a liquid guide part; the liquid storage bottle is screwed into the connecting part; the slot comprises a central limit part and a lateral limit part.

Abstract: In a method for channel assignment according to the invention, a TDD transmission method with timeslots as channels is used for radio transmission between a base station and mobile stations, with a switching point separating timeslots for a up link direction and timeslots for a down link direction. A transmission parameter relating to a transmission quality is in each case defined for the radio transmission between the base station and a plurality of mobile stations. The mobile stations with the qualitatively better transmission parameter are preferably assigned timeslots close to the switching point.
