FIELD: atomization.
SUBSTANCE: spray unit and a spray device having high strength. The spray unit (1) contains: a support (12) and a heating element (11), which has the shape of a plate and is located on the support (12). The heating element (11) contains a heating section (111), at least one electrode section (112) and at least one fixing section (113). The two sides of the heating section (111) in the first direction (a) are bent in the third direction (c), so that one side of the heating section (111) in the third direction (c) is concave and the other side of the heating section (111) in the third direction (c) is arcuate. The heating section (111) includes a heating circuit (1111) electrically connected to at least one electrode section (112) to generate heat when power is applied to at least one electrode section (112). The support (12) is provided with a cavity (12a) having an opening in the first direction (a), the heating element (11) is located on the support (12), the heating section (111) is located in the opening of the cavity (12a), and at least one fixing section (113) is built into the support (12). The concave side of the heating section (111) faces the cavity (12a) and together with the cavity (12a) forms a containing chamber (13) configured to receive the liquid-conducting element and ensure that the liquid-conducting element contacts the heating element (11). The support (12) is provided with at least one fluid inlet (12d) communicating with the containment chamber (13) for fluid to enter the containment chamber (13). The first direction (a) and the third direction (c) are not parallel to each other. When a liquid conducting element is provided in the containing chamber (13) and conducts liquid from at least one liquid inlet (12d) to the heating element (11), the heating element (11) heats and atomizes the liquid.
EFFECT: creation of a spray unit having high structural strength, capable of operating with different liquid inlet modes and providing uniform heating.
