[0008] Preferably, the thermal insulation layer extends from the first end of the gun barrel to the second end thereof, so as to achieve full thermal insulation during the gluing process of the hose, which helps to ensure the stability of the gluing temperature.

[0009] Preferably, the thermal insulation layer is made of aluminum silicate ceramic fiber paper, the aluminum silicate ceramic fiber paper roll is set as a paper tube, and the outer surface of the paper tube is bonded to the inner wall of the gun barrel.

[0010] Since the aluminum silicate ceramic fiber paper is relatively thin, in order to ensure the thermal insulation effect, preferably, the aluminum silicate ceramic fiber paper roll is arranged into a plurality of paper tubes, and the plurality of paper tubes are arranged from the inside to the outside, and the outer surfaces of the inner paper tubes of two adjacent paper tubes are bonded to the inner surfaces of the outer paper tubes.

[0011] Preferably, the thermal insulation layer is made of thermal insulation coating, and the thermal insulation coating is coated on the inner wall of the gun barrel.

[0012] The utility model provides a glue gun with heat preservation function, which has the following beneficial effects:

[0013] Based on the structure and size of the existing glue gun, the present application sets an insulation layer in the barrel of the glue gun, and still makes its inner diameter larger than the outer diameter of the hose, thereby achieving the insulation of the glue liquid in the hose installed in the barrel without affecting the normal use of the glue gun, so that during the gluing process of the same hose, the early gluing temperature and the later gluing temperature tend to be consistent, which helps to ensure the consistent gluing effect of the same hose; by setting the insulation layer from the first end of the barrel and extending it toward the second end of the barrel, preferably extending it to the second end of the barrel, the whole process of gluing the hose is achieved. Insulation, which helps to ensure the stability of the glue coating temperature. BRIEF DESCRIPTION OF THE DRAWINGS
