Description

Technical Field

[0001] The present application relates to the technical field of heating devices, and more specifically, to a hot melt adhesive heating device. Background Art

[0002] As we all know, hot melt adhesive is a thermoplastic material that becomes sticky when heated to a certain temperature, and then a heating device is used to align and heat it. Currently, most of the hot melt adhesive heating devices on the market are handheld in appearance. The hot melt adhesive stick is inserted into the heating chamber, and the electric thermal resistor generates heat to heat the solid hot melt stick into liquid. The material is then discharged through the glue dispensing head at one end of the heating device, making it more convenient to adhere the required objects.

[0003] However, most of the hot melt adhesive heating devices currently available on the market cannot filter the hot melt adhesive after it is melted but before it is discharged. As a result, when impurities are mixed in the solid hot melt adhesive, the adhesion of the hot melt adhesive will be affected, thereby greatly reducing the use effect of the hot melt adhesive and thus reducing the practicality of the device.
