Description

  The present invention relates to a heating evaporator, and more particularly to a heating evaporator having an improved structure for easy assembly.

  2. Description of the Related Art Conventionally, heating evaporators that vaporize and evaporate chemicals suitable for room deodorization and aroma have been widely used.

This type of heating evaporator has a liquid container equipped with a liquid absorption core for sucking up the internal chemical solution installed in the lower part of the evaporator main body, and this liquid absorption by a heating element such as a heater provided in the evaporator main body. By heating the wick, vaporization and transpiration of the chemical solution is promoted, and the structure diffuses to the outside from the transpiration port provided above the evaporator body.
Conventional heating evaporators have a problem that the number of components and fastening screws is large and the assembly process is complicated.

  Therefore, the heating evaporator has a front case with a screw receiving boss, a mounting member having a through hole for fixing and supporting the heating element and the screw receiving boss being inserted, and a screw receiving boss inserted into the through hole. The proposal comprised with the main body rear case provided with the boss | hub receiving part for fastening with a screw is made (for example, refer patent document 1).
