[0022] Please refer to Figs. 1-4 ​​The utility model provides a kind of heating device of hot melt glue gun, including heating head 7, the heating head 7 surface is provided with heat-collecting component, heating head 7 one end is fixedly connected with glue outlet 5, glue outlet 5 is internally provided with the through glue cavity 9, heating head 7 is provided with the through heating cavity 10, and heating cavity 10 and glue cavity 9 are interconnected, heating head 7 is provided with heating component away from glue outlet 5 one end, heating head 7 is provided with heating source by heating component, in turn effectively melt hot melt adhesive inside heating head 7, simultaneously under the cooperation of heat-collecting component, it can guarantee that heat is not lost faster, guarantee heating effect.

[0023] In embodiments, the heating component includes PTC ceramic heating ring 1, fixed sleeve ring 2 and clamping plate 6, the surface of heating head 7 is fixedly connected with clamping plate 6, the outer side of clamping plate 6 is sleeved with PTC ceramic heating ring 1, and PTC ceramic heating ring 1 is used in cooperation with heating head 7 through clamping plate 6, the inner side wall of PTC ceramic heating ring 1 is fixedly connected with fixed sleeve ring 2, the device can be fixed on the hot melt gun through the cooperation of clamping plate 6 and fixed sleeve ring 2, and then PTC ceramic heating ring 1 can be effectively sleeved on heating head 7, so that it can directly heat heating head 7, to ensure the efficiency of heat conduction.

[0024] In embodiments, the heat-collecting component includes extrusion sleeve 3, rubber heat insulation layer 4, limiting plate 11 and limiting groove 12, the surface of heating head 7 is fixedly connected with limiting plate 11, and the surface of heating head 7 is sleeved with rubber heat insulation layer 4, the inner side wall of rubber heat insulation layer 4 is provided with limiting groove 12, limiting plate 11 is placed in limiting groove 12, and extrusion sleeve 3 is sleeved on the surface of rubber heat insulation layer 4, the heat can be better insulated in heating cavity 10 by sleeving rubber heat insulation layer 4 on the surface of heating head 7, to ensure effective heating of hot melt adhesive.

[0025] In embodiments, the heating head 7 is provided with anti-overflow ring 8, and the anti-overflow ring 8 is placed in the heating cavity 10, the anti-overflow ring 8 is arranged above the heating cavity 10, the hot melt adhesive expands after heating, and the hot melt adhesive can be prevented from dripping from the glue cavity 9 by the blocking of the heating cavity 10, to improve the safety of the device.

[0026] When the user starts the hot melt glue gun, the power supply will supply power to the PTC ceramic heating ring 1, and the PTC ceramic heating ring 1 will rapidly heat up under the action of the current due to its positive temperature coefficient characteristic, generating stable heat. The heat generated by the PTC ceramic heating ring 1 is directly transmitted to the heating head 7 through the fixed sleeve ring 2. Since the heating head 7 adopts an integrated design, it not only improves the efficiency of heat conduction, but also makes it more convenient and fast to replace or maintain the heating head 7 when needed. The heat gathering components on the surface of the heating head 7 begin to play a role, and the rubber heat insulation layer 4 effectively blocks the heat from spreading outward, ensuring that most of the heat is concentrated in the heating cavity 10. The design of the limiting plate 11 and the limiting groove 12 ensures that the rubber heat insulation layer 4 is tightly attached to the surface of the heating head 7, further enhancing the heat insulation effect. The use of the extrusion sleeve 3 increases the stability of the entire system, preventing the rubber heat insulation layer 4 from shifting during use. As the temperature of the heating head 7 rises, the hot melt glue in the heating cavity 10 begins to soften and eventually melts completely. The design of the anti-overflow ring 8 plays a key role in this process. It is located above the heating cavity 10 and can effectively prevent the hot melt glue from overflowing due to thermal expansion, avoiding accidental dripping of the hot melt glue from the glue outlet 9, thereby improving the safety and cleanliness of the device. When the hot melt glue is completely melted and reaches the appropriate fluidity, the user can push the handle of the hot melt glue gun to make the melted hot melt glue flow out through the glue outlet 5 at the end of the heating head 7 and the glue outlet 9 for bonding or sealing purposes.

[0027] The heating head 7 is integrally formed, which can effectively improve the replacement rate. When it is blocked or damaged, it can be easily removed through the quick release, thereby facilitating the user's actual operation. The anti-overflow ring 8 is arranged above the heating cavity 10. After heating, the hot melt glue expands thermally and is blocked by the heating cavity 10, which can eliminate the dripping of the hot melt glue from the glue outlet 9, thereby improving the safety of the device. The heat gathering components can effectively improve the heat gathering effect of the heat, thereby effectively releasing the heat on the hot melt glue. The PTC ceramic heating ring 1 is effectively sleeved on the heating head 7 through the heating assembly, thereby making the heating effect more direct and improving the heating rate.

[0028] This specification is described in terms of embodiments, but not every embodiment contains only one independent technical solution. The description of the specification is for clarity only, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
