Description

Technical Field

[0001] The utility model relates to the technical field of hot glue guns, in particular to a leak-proof hot glue gun. Background Art

[0002] A hot glue gun is a common handheld tool used to heat and melt hot melt glue sticks (hot melt adhesive strips) and apply them to objects that need to be bonded. These glue sticks are usually heated to a molten state by the heating element of the hot melt glue gun, and then squeezed out of the gun muzzle by pressure. Hot glue guns are widely used in the fields of handicraft production, home repair, decoration, packaging, DIY projects, etc. They are easy to operate and use, can quickly bond objects together, and the bonding effect is long-lasting and firm. After the hot glue gun is sprayed, the hot melt glue remaining in the hot glue gun will flow out of the hot glue gun head and drip onto the surface of the workpiece, which not only causes a waste of hot melt glue, but also makes it difficult for the operator to clean up the dripping hot melt glue. However, the existing hot glue gun does not have a good leak-proof structure to prevent the hot glue gun from leaking glue just after use. Therefore, those skilled in the art provide a leak-proof hot glue gun to solve the problems raised in the above background technology. Utility Model Content

[0017] The working principle of the utility model is as follows: a hot melt adhesive strip is put in from the adhesive inlet rubber ring, passed through the hot melt adhesive strip pusher, and stuck into the hot melt adhesive strip groove; a power cord at the lower end of the hot glue gun shell provides power to the hot glue gun; the adjusting handle is pinched, the adjusting handle is rotated, the adjusting handle drives the linkage to move right, the linkage drives the adjusting movable rod at the lower side of the hot melt adhesive strip pusher to move right in the adjusting groove; at the same time, the adjusting handle stretches the second adjusting spring, the hot melt adhesive strip pusher drives the hot melt adhesive strip to move right, the adjusting handle is released, and the second adjusting spring drives The adjustment handle returns to its position, and the adjustment handle pushes the linkage to move to the left. The linkage drives the hot melt adhesive strip pusher to move to the left. The adjustment movable rod moves and returns to its position in the adjustment slot. The glue inlet rubber ring prevents the hot melt adhesive strip from moving to the left and falling out of the hot glue gun. Turn on the switch button of the hot glue gun, and the control circuit board controls the heating element to heat the hot melt adhesive strip. The hot melt adhesive strip is melted into hot melt adhesive. Pinch the adjustment handle, and the hot melt adhesive strip pusher pushes the hot melt adhesive strip to move to the right. The hot melt adhesive strip pushes the hot melt adhesive into the leak-proof structure. The hot melt adhesive is pushed by the hot melt adhesive strip. The glue pushes the leak-proof block inside the leak-proof opening to move upward, and the leak-proof block pushes the connecting block to move upward. The connecting block compresses the first adjusting spring, and the leak-proof convex block prevents the hot melt glue from flowing out from the left side. The hot melt glue flows out of the gun nozzle to stick to the object. After the sticking is completed, the switch button is turned off, the control circuit board controls the heating element to stop heating, the pinching of the adjusting handle is stopped, the hot melt glue strip pusher stops pushing the hot melt glue strip, the hot melt glue strip stops pushing the hot melt glue, the hot melt glue has no pressure, and cannot squeeze the leak-proof block. The first adjusting spring pushes the connecting block to move downward, and the connecting block The leak-proof block is driven to move downward, and the leak-proof block blocks the leak-proof opening. The sealing rubber on the upper end of the leak-proof block prevents the hot melt adhesive from leaking out. The leak-proof structure can effectively prevent the hot melt adhesive from accidentally leaking out when not working, thereby reducing the waste of hot melt adhesive. The leak-proof structure prevents the hot melt adhesive from dripping onto the work surface or other surfaces, keeping the working environment clean and tidy, improving work efficiency, maintaining product quality and the hygiene of the production environment, and at the same time preventing the risk of accidents caused by hot melt adhesive dripping, such as burns or other injuries, and effectively protecting the safety of operators.
