Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot melt glue gun technology, and in particular to a lithium battery wireless hot melt glue gun. Background Technology
[0002] Hot melt glue guns melt glue sticks and then squeeze out liquid glue, which can be applied to the areas to be glued to achieve adhesion. They are widely used in industries such as building decoration, electronics, automobiles and auto parts. Existing hot melt glue guns require a 220V power supply. Since the power cord of a hot melt glue gun is of a fixed length, it greatly limits the scope of use. At the same time, the glue stick only adheres to the glue gun with the melted end, which makes it easy for the glue stick to fall out of the glue gun due to vibration during the movement of the hot melt glue gun. Therefore, a lithium battery wireless hot melt glue gun was designed to solve the above problems. Utility Model Content
[0003] To address the shortcomings of existing glue guns, the purpose of this invention is to provide a lithium-ion battery-powered wireless hot melt glue gun, which has advantages such as unrestricted application range and prevention of glue stick detachment during movement.
[0004] To achieve the above objectives, the present invention employs the following technical solution: a lithium-ion wireless hot melt glue gun, comprising a housing, a trigger, a delivery mechanism, a heating element, a battery, a circuit board, a damping rubber ring, a nozzle, and a leak-proof rubber sleeve. The housing has a tube and a handle radially disposed on one side. The handle contains the battery and the circuit board. The nozzle is located at one end of the tube away from the handle, and a damping rubber ring is located at the other end of the tube. The inner ring of the damping rubber ring has a V-shaped convex edge, which provides damping for the movement of the glue stick. A heating element is located inside the tube on one side of the nozzle. A leak-proof rubber sleeve is fitted on one side of the heating element. A delivery mechanism for delivering the glue stick is located on one side of the leak-proof rubber sleeve. The trigger is hinged between the tube and the handle and is used to drive the delivery mechanism to move the glue stick.
[0005] Preferably, the damping rubber ring, heating tube, nozzle, and leak-proof rubber sleeve are coaxial;
[0006] Preferably, the conveying mechanism includes a linkage rod, a C-shaped claw, and a positioning sleeve. The positioning sleeve is axially slidably connected inside the tube body. The bottom of the positioning sleeve has an opening. The middle part of the C-shaped claw is hinged to the opening at the bottom of the positioning sleeve via a pivot. One end of the C-shaped claw located inside the positioning sleeve has protruding trapezoidal teeth. The other end of the C-shaped claw is hinged to one end of the linkage rod, and the other end of the linkage rod is hinged to a trigger.
[0007] Preferably, the housing is further provided with an observation opening at the position corresponding to the positioning sleeve;
[0008] Preferably, a switch for controlling the power of the glue gun is provided on one side of the handle, and a charging port for charging is provided at the bottom of the handle;
[0009] Preferably, the hinge between the trigger and the housing is further provided with a torsion spring to force it to spring out;
[0010] Preferably, the inner diameter of the damping rubber ring is larger than the outer diameter of the rubber rod, and the inner ring of the damping rubber ring has a V-shaped convex edge with an inner diameter smaller than the outer diameter of the rubber rod.
[0011] The beneficial effects of this utility model are: 1. Powered by a built-in rechargeable battery, the hot melt glue gun is not limited by the power cord during use, thus achieving an unrestricted range of use; 2. When the glue stick is inserted into the glue gun, the inner diameter of the damping ring is smaller than the outer diameter of the glue stick, so that the V-shaped convex edge can cover the glue stick to provide damping, thereby preventing the glue stick from falling off during the movement of the glue gun.

[0019] Please see Figures 1 to 4 The embodiments of this utility model include:
[0020] A lithium-ion wireless hot melt glue gun includes a housing 1, a trigger 2, a delivery mechanism 3, a heating tube 4, a battery 5, a circuit board 6, a damping rubber ring 7, a nozzle 8, and a leak-proof rubber sleeve 9. The housing 1 has a tube body 11 and a handle 12 radially disposed on one side. The handle 12 houses the battery 5 and the circuit board 6. The nozzle 8 is located at one end of the tube body 11 away from the handle 12, and the damping rubber ring 7 is located at the other end of the tube body 11. The inner ring of the damping rubber ring 7 has a V-shaped protrusion 71, which provides damping for the movement of the glue stick. The heating tube 4 is located inside the tube body 11 on one side of the nozzle 8. The leak-proof rubber sleeve 9 is sleeved on one side of the heating tube 4. The delivery mechanism 3 for delivering the glue stick is located on one side of the leak-proof rubber sleeve 9. The trigger 2 is hinged between the tube body 11 and the handle 12 and is used to drive the delivery mechanism 3 to move the glue stick.
[0021] The damping rubber ring 7, heating tube 4, nozzle 8 and leak-proof rubber sleeve 9 are coaxial;
[0022] The conveying mechanism 3 includes a linkage rod 31, a C-shaped claw 32, and a positioning sleeve 33. The positioning sleeve 33 is axially slidably connected inside the tube body 11. The bottom of the positioning sleeve 33 has an opening. The middle part of the C-shaped claw 32 is hinged to the opening at the bottom of the positioning sleeve 33 via a rotating shaft. One end of the C-shaped claw 32 located inside the positioning sleeve 33 has a protruding trapezoidal tooth 321. The other end of the C-shaped claw 32 is hinged to one end of the linkage rod 31, and the other end of the linkage rod 31 is hinged to the trigger 2.
[0023] The housing 1 is also provided with an observation opening 13 at the position corresponding to the positioning sleeve 33;
[0024] The handle 12 has a switch 14 on one side for controlling the power of the glue gun, and a charging port 15 at the bottom of the handle 12 for charging.
[0025] The trigger 2 and housing 1 are also provided with a torsion spring at the hinge point to force it to pop out;
[0026] The inner diameter of the damping rubber ring 7 is larger than the outer diameter of the rubber rod, and the inner ring of the damping rubber ring 7 has a V-shaped convex edge 71 with an inner diameter smaller than the outer diameter of the rubber rod.
[0027] With the above settings, its specific working principle in actual operation is as follows:
[0028] First, insert the glue stick into the gun body from the damping rubber ring 7 on one side of the glue gun, so that the glue stick passes through the positioning sleeve 33 and the leak-proof rubber sleeve 9 until it is against the heating tube 4 and cannot move. At this time, since the inner diameter of the inner circle of the damping rubber ring 7 is smaller than the outer diameter of the glue stick, the V-shaped convex edge 71 can cover the glue stick to provide movement damping, thereby preventing the glue stick from falling off during the movement of the glue gun.
[0029] When using the hot melt glue gun, by turning on the switch 14 on one side of the handle 12, the internal battery 5 is powered up through the circuit board 6 to heat the heating tube 4; the hot melt glue gun is powered by the built-in rechargeable battery 5, so that it is not limited by the power cord when using the hot melt glue gun, thus achieving the effect of unlimited use range.
[0030] During the dispensing process of trigger 2, the C-shaped claw 32 rotates at the hinge position of the central pivot under the drive of the linkage rod 31, so that the trapezoidal teeth 321 of the C-shaped claw 32 located in the positioning sleeve 33 press against the glue stick upward, thereby fixing the glue stick against the positioning sleeve 33. During the continuous pulling of trigger 2, trigger 2 drives the C-shaped claw 32 and the positioning sleeve 33 to move towards the nozzle 8 through the linkage rod 31, thereby continuously conveying the glue stick to the heating tube 4 for melting. The melted liquid glue is then ejected from the nozzle 8.
[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
