Heating Device for the Hot Melting Chamber of a Hot Melt Glue Gun

Abstract

The present invention relates to a heating device for the hot melting chamber of a hot melt glue gun, being a heating device fixed outside the hot melting chamber for heating. The heating device comprises two opposite holding parts configured on the outside of the hot melting chamber. Each holding part holds a resistor block. The resistor block on each side is tightly attached with an electrode plate. The electrode plates on the two sides are bonded together, so that the electrode plate can act as the common positive pole of the power supply to the resistor block, and meanwhile, the hot melting chamber can act as the common negative pole of the power supply to the resistor block. In this way, the configuration of an electrode plate under the resistor block can be omitted to reduce the size of the heating device, and less connecting wires are required between each resistor block and the positive and negative poles of the power supply, thus simplifying the welding and assembling operations.
