Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 and 2, the hand dryer with heat dissipation function is composed of a machine body 1, a surface shell 2, a water receiving tank 3, an indicator lamp 4, a heat radiator 5, a power switch 6 and a power line 7, and is characterized in that: the surface shell 2 is fixed on the upper part of the machine body 1; the water receiving tank 3 is fixed at the lower part of the machine body 1; the indicator lamp 4 is fixed in the middle of the front end of the surface shell 2; the radiator 5 is fixed at the side position of the surface shell 2; the power switch 6 is set at the upper part of the side surface of the machine body 1; the power cord 7 is established at a position below the power switch 6.

The heat sink 5 comprises a mounting plate 51, a heat dissipation layer 52, a storage battery 53, heating wires 54, electric wires 55, a heat protection metal sheet 56, a temperature control switch 57, a contact plate 58, a heat dissipation fan 59 and a heat dissipation groove 510, wherein the heat dissipation layer 52 is arranged on the periphery of the mounting plate 51; the storage battery 53 is placed at the left end position of the mounting plate 51; the heating wire 54 is placed on the upper portion of the mounting plate 51 and is connected to the battery 53 through the electric wire 55; the thermal protection metal sheet 56 is connected with the storage battery 53 through the electric wire 55 and placed at the lower end of the heating wire 54; the temperature control switch 57 is placed at the lower right end of the thermal protection metal sheet 56; the heat dissipation fan 59 is fixed at the lower right corner of the mounting plate 51; the left end of the heat radiation fan 59 is connected with the contact plate 58 through a wire 55; the heat dissipation groove 510 is disposed at an upper end of the heat dissipation fan 59.

Further, the thermal protection metal sheet 56 is always in communication with the temperature control switch 57.

When the user uses the hand dryer, the heating wire 54 is heated to cause the internal temperature to be too high, and at the moment, part of the internal heat is radiated and discharged through the radiating layer 52; on one hand, the heating wire 54 heats the hot air blowing downwards, so that the lower end of the thermal protection metal sheet 56 is bent downwards to touch the temperature control switch 57 to be connected with the contact plate 58 to form a loop, so that the heat dissipation fan 59 performs heat dissipation work and is discharged from the heat dissipation groove 510, and the internal temperature of the machine body is reduced; when the hand drier stops working, the heating wire 54 stops heating, the thermal protection metal sheet 56 returns to the original state, the temperature control switch 57 and the contact plate 58 are in the disconnected short-circuit state, and the circuit of the cooling fan 59 is disconnected and stops rotating.
