The utility model relates to the technical field of atomization equipment, and provides a heating device and atomization equipment. The heating device comprises a heating body, the heating body is internally provided with a heating cavity penetrating in the first direction, the heating cavity comprises a plurality of heating sections sequentially connected in the first direction, and in the first direction, the maximum size of the heating section of at least one end of the heating body in the second direction is smaller than the maximum size of the adjacent heating section in the second direction; and the heating piece is arranged on the outer side of the heating body, and the heating piece can be electrically connected with the power supply device so as to enable the heating body to heat in a power-on state. According to the technical scheme, the heating cavity of the heating body is divided into the multiple heating sections in the first direction, different areas of the aerosol generating rod can be heated differentially by means of the fact that the distances between the heating sections different in size in the second direction and the corresponding areas on the aerosol generating rod are different, and therefore heat loss is reduced, and the heating efficiency is improved. The atomization speed of the atomization matrix is increased, and the heating atomization efficiency is improved.

This utility model relates to the field of air conditioning unit technology, and more particularly to an energy-saving constant temperature and humidity air conditioning unit, comprising a channel for maintaining constant temperature and humidity and an air conditioning unit. The channel is sequentially provided with an air inlet section, a primary / medium efficiency filter section, a heating section, a pre-cooling section, a dehumidification section, a humidification section, a cooling section, an air outlet section, and a terminal filter section. The air conditioning unit is equipped with a radiator and two evaporators. The radiator is located within the heating section, and the two evaporators are respectively located within the pre-cooling and cooling sections. This utility model uses an air conditioning unit to install the evaporators of the refrigeration system within the pre-cooling and cooling sections of the air being processed channel. It utilizes the direct evaporation of refrigerant to cool the air. When the air flows over the outer surface of the evaporator, it is cooled while its moisture content decreases. Simultaneously, the radiator heats the air inlet section, reducing the need for steam heating. This unit can solve the problem of excessive humidity during the summer rainy season, improve energy efficiency, and reduce energy consumption.
