The first embodiment,

The glue extruder in this embodiment is a hot melt glue gun or a hot melt glue pen, taking the hot melt glue gun as an example, as shown in fig. 1 to 4, and includes a housing, a gun barrel 100 installed in the housing, and a heating element for heating the gun barrel 100, where the housing is formed by assembling a left half housing and a right half housing, the heating element includes two electrode plates 200 and a heating plate 300 clamped between the two electrode plates 200, the two electrode plates 200 are respectively connected with positive and negative electrodes of a power supply through wires, after power is turned on, the heating plate 300 generates heat and heats the gun barrel 100 to melt a glue stick in the gun barrel 100, an elastic split ring 400 is clamped on the gun barrel 100, the elastic split ring 400 is approximately C-shaped, and the heating element is clamped and fixed between the gun barrel 100 and the elastic split ring 400, so that the heating element is fixed on the gun barrel.

Because the elastic split ring 400 in this embodiment can elastically deform to a certain extent, so that the opening of the elastic split ring 400 can be enlarged, when the heating component needs to be disassembled, the elastic split ring 400 can be separated from the gun barrel 100 to disassemble the heating component only by expanding the opening of the elastic split ring, the disassembly is simple and convenient, and the difficulty in later maintenance is reduced; meanwhile, due to the design, the elastic split ring 400 cannot be damaged during disassembly, and the heating assembly can be conveniently assembled again.

In this embodiment, the barrel 100 includes a tubular body 110 and a rectangular mounting groove 120 disposed outside the tubular body 110, the rectangular mounting groove 120 extends along a length direction of the tubular body 110, one of the electrode plates 200 is attached to a bottom wall of the rectangular mounting groove, and the other electrode plate 200 is exposed at a notch of the rectangular mounting groove, and at this time, the electrode plate 200 and the heat generating sheet 300 are both rectangular sheets, so that a contact area between the heat generating component and the tubular body 110 can be increased, and thus, the heat conduction efficiency is improved. Elasticity split ring 400 is fixed heating element in rectangle mounting groove 120, during the equipment, as long as guarantee that the opening of elasticity split ring 400 staggers with the notch of rectangle mounting groove 120 can, so design can enough carry out prepositioning to heating element through rectangle mounting groove 120 to this reduces heating element's the assembly degree of difficulty, can be convenient for again electrode slice 200 and heating element 300's machine-shaping.

Preferably, two parallel limiting plates 111 are disposed on the outer side of the tube 110 in this embodiment, the limiting plates 111 are formed by extending the outer side wall of the tube 110 downward, and the two limiting plates 111 and the outer side wall of the tube form a rectangular mounting groove 120. So design, can strengthen the structural strength of body 110, avoid body 110 to be heated to take place to warp and lead to the elasticity split ring 400 to clamp not jail and drop.

Secondly, the two limiting plates 111 are provided with correspondingly arranged positioning notches 1110, and the elastic split ring 400 is clamped at the positioning notches 1110. By the design, the elastic split ring 400 can be prevented from axial displacement, so that the clamping firmness of the elastic split ring 400 and the fixing firmness of the heating component are increased.

It will be appreciated that the outer side wall of the tubular body may also be partially recessed to form the rectangular mounting groove.

In order to increase the heat conduction efficiency of barrel 100 and in order to promote the melten gel speed and prolong the life of elasticity split ring 400, barrel 100 and elasticity split ring 400 in this embodiment are the metalwork, and the heating element still includes the insulating paper 500 of cladding in the heating element outside, and such design can be kept apart heating element and barrel 100 and elasticity split ring 400 to avoid taking place the short circuit phenomenon.

In order to avoid crushing the electrode plate 200 after the elastic split ring 400 is clamped, in the embodiment, an aluminum backing plate 600 is further arranged in the housing, and the aluminum backing plate 600 is pressed between the heating component and the elastic split ring 400. By the design, the aluminum backing plate 600 can protect the electrode plate 200, so that the electrode plate 200 is prevented from being crushed by the elastic split ring 400.

In order to further reduce the difficulty of disassembling the elastic split ring 400, at least one end of the elastic split ring 400 in this embodiment has a flange 410 bent outward, and the flange 410 is connected with the elastic split ring 400 through a fillet transition. So design, can strengthen the structural strength of elasticity split ring 400, can enlarge the opening of elasticity split ring through gripping hem 410 again when dismantling to this further reduces the dismantlement degree of difficulty of elasticity split ring 400.

Finally, in order to improve the heating effect of the barrel 100, the heat generating sheet 300 in this embodiment includes a plurality of PTC heat generating sheets, e.g., 3, 4, 5, etc., installed in parallel between the two electrode sheets 200.
