when the atomizing dispenser is in actual use, the spray gun is vertically positioned above an object to be sprayed and has moderate height by adjusting the length of the telescopic rod and adjusting the first spherical hinge and the second spherical hinge, the hot melt adhesive is put into the adhesive melter to be melted, the hot melt adhesive is conveyed to the atomizing area in the connecting piece through the adhesive conveying pipe and is dispersed into micro liquid drops by high-speed air flow generated in the pressure pump, the hot melt adhesive which is dispersed into the micro liquid drops enters the spray gun and is sprayed out from the nozzle of the spray gun after passing through the porous composite plug, because the hot melt adhesive is sprayed out from the nozzle of the spray gun after passing through the porous composite plug, after the adhesive spraying operation is finished, the dispenser stops working, the valve in the electromagnetic valve is closed, so that a partition is formed in the atomizing area of the connecting piece to prevent the hot melt adhesive in the atomizing area from entering the spray gun, and glue remained in the spray gun exists in the porous composite plug, because the porous composite plug is built to form a three-dimensional network structure, the leakage of the hot melt adhesive in the hot melting and solidification process is limited, the hot melt adhesive can not flow out of the porous composite plug in the process of converting the liquid state from the solid state, the phenomena of glue hanging and glue dripping can not occur on the spray gun, and a heat conduction passage formed by arranging the pretreated hexagonal boron nitride nanosheets exists in the porous composite plug, the heat conduction performance of the porous composite plug is improved, the heat generated by a heating area in the connecting piece can be quickly transferred in the porous composite plug when the atomizing dispenser is restarted, the melting of the hot melt adhesive at the spray gun is accelerated, the preheating time is shortened, and the working efficiency of the atomizing dispenser is improved.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
