Description

Warm-air drier Technical Field The utility model relates to the field of warm air blowers, in particular to a warm air blower. Background The warm-air machine is a small heating device which can generate hot air by electric energy and is mainly used for quickly heating local space or small range. The small warm-air blower is generally used when the temperature of the warm-air blower is low in winter, people need to store the warm-air blower in other seasons, the warm-air blower is used again in the next winter, the front surface and the rear surface of the warm-air blower are communicated with internal electric heating wires and other structures, and when the air humidity is high in the south of the warm-air blower, the moisture easily influences the internal electric heating wires and other electrical structures, so that the service life of the internal structure of the warm-air blower is influenced. New solutions are therefore required to address this problem. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a warm air blower. The technical aim of the utility model is achieved through the following technical scheme that the fan heater comprises a machine body, a heat insulation net is arranged on the front side of the machine body, a ventilation grille is arranged on the rear side of the machine body, protective shells are arranged on two sides of the machine body, rolling columns are arranged in the two protective shells, the rolling columns can rotate in the protective shells, a shielding cloth is fixedly connected onto the rolling columns, one end of the shielding cloth is always exposed out of the protective shells, the directions of the openings of the two protective shells are opposite, one end of the shielding cloth can be fixed on the machine body, the rolling columns can give winding force to the shielding cloth towards the directions of the protective shells, and a containing groove is formed in the ventilation grille. The utility model is further arranged that the front side and the rear side of the machine body are fixedly connected with an upper rail shell and a lower rail shell, one side of the upper rail shell and one side of the lower rail shell, which face each other, are provided with sliding grooves, the heat insulation net and the ventilation grid are positioned between the corresponding upper rail shell and the lower rail shell, and the upper end and the lower end of the shielding cloth can be embedded into the sliding grooves. The utility model is further characterized in that elastic strips are fixedly connected to the inner walls of the upper rail shell and the lower rail shell, and the elastic strips are used for propping the covering cloth against the machine body. The utility model further provides that one end of the shielding cloth, which is exposed out of the protective shell, is fixedly connected with a retaining sheet.
