2. Description of the Related Art
A conventional therapeutic apparatus in accordance with the prior art shown in FIG. 1 comprises a housing 1 having a plurality of inlet holes 2, a filtering net 3 mounted in the housing 1 and aligning with the inlet holes 2, a flow channel 4 mounted in the housing 1 and having a first end aligning with the inlet holes 2 and a second end protruding outward from the housing 1, a connecting pipe 5 connected with the second end of the flow channel 4, an electric heater 8 mounted in the housing 1 and having an electric heating filament 7 extending into the flow channel 4, a fan 6 mounted in the flow channel 4 and disposed between the inlet holes 2 and the electric heating filament 7. In operation, ambient air in introduced through the inlet holes 2 into the flow channel 4 by operation of the fan 6. Then, the electric heating filament 7 heats the air to form a hot air flow which is blown by the fan 6 to pass through the connecting pipe 5 into an affected part of a user, such as the nose or mouth of the user so as to cure the affected part of the user. The heat or temperature from the electric heating filament 7 is controlled by a temperature regulator. However, when the hot air flow is blown outward from the connecting pipe 5, the ambient condition outside of the housing 1 will affect the hot air flow, so that the temperature of the hot air flow is not controlled easily. In addition, micro dust in the air will mix with the hot air flow to be inhaled into the affected part of the user, thereby decreasing the curing effect. Further, the fan 6 is far spaced from the electric heating filament 7 to prevent scalding and reduce the temperature of the hot air flow, and the connecting pipe 5 has a long distance to release the high temperature of the hot air flow so that the conventional therapeutic apparatus has a larger volume and is not carried and operated easily.
