[0002] In existing glue gun technology, some glue guns have the problem that the battery is not removable or is inconvenient to remove. When the battery is depleted, the entire glue gun needs to be replaced or the battery needs to be replaced through complicated operations, which increases the cost of use and the difficulty of operation.

[0003] Meanwhile, the trigger mechanism of traditional glue guns suffers from low transmission efficiency and poor stability when propelling the glue strip, resulting in uneven glue dispensing and affecting the performance. Furthermore, some glue guns have poorly designed glue guiding and melting structures, making the glue strip prone to clogging during transport and melting, reducing work efficiency. Therefore, there is an urgent need for a new type of glue gun that can solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a glue gun with a trigger structure and a detachable battery structure, so as to solve the technical problems of existing glue guns, such as inconvenient battery replacement, low trigger transmission efficiency, and easy blockage of glue guiding and melting.

[0005] To solve the above technical problems, the present invention is achieved through the following solution: The present invention provides a glue gun with a trigger structure and a detachable battery structure, including a power supply unit, a glue guiding unit arranged at an angle to the power supply unit, and a glue melting unit disposed in the glue dispensing direction of the glue guiding unit. The glue melting unit has a glue melting channel and a glue dispensing nozzle disposed at the outer end of the glue melting channel. The battery in the power supply unit is a detachable structure.

[0006] The adhesive guiding part is provided with an adhesive guiding channel inside, which is linearly connected to the melt adhesive channel. The adhesive guiding channel is provided with a movable part that can reciprocate in the direction of adhesive guiding. The movable part has an adhesive channel for the adhesive strip to pass through and a lower opening.

[0007] A trigger structure is provided at the corner between the power supply section and the adhesive guiding section, and the trigger structure includes:

[0008] A locking block, the first end of which extends from the lower opening into the adhesive channel inside the movable part, the locking block being able to drive the movable part to move when it moves;

[0009] A spring, one end of which is sleeved on the first positioning post inside the guide rubber part, and the other end is connected to the locking block to form a reset mechanism;

[0010] A connecting plate, the first end of which is rotatably connected to the second end of the locking block;

[0011] The trigger handle has its inner end rotatably connected to the second end of the connecting plate, and its outer end extends out of the guide rubber part. The handle body of the trigger handle is also rotatably connected to the second positioning post in the power supply part, so that the trigger handle can rotate with the second positioning post as a fulcrum, thereby pulling the connecting plate to move.

[0012] Furthermore, the detachable structure includes a snap-on cover that can be snapped and fixed to the battery inlet at the tail end of the power supply unit.

[0013] Furthermore, the guide section is provided with a track, and the movable part slides on the track.

[0014] Furthermore, the locking block has a toothed pattern on the end face of its first end.

[0015] Furthermore, the locking block is a curved block.

[0016] Furthermore, the connecting plate is a straight panel.

[0017] Furthermore, the melt section is equipped with a heating structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In the glue gun of this utility model, the battery is designed to be detachable: the detachable structure of the battery in the power supply section is fixed by the buckle between the cover and the battery inlet, which makes it convenient for users to quickly replace the battery when the battery is depleted, without having to replace the entire glue gun, thus reducing the cost of use and improving the convenience and endurance of the glue gun.

[0020] 2. In the glue gun of this utility model, the trigger structure enables efficient reset: the unique trigger structure, through the coordinated work of the trigger handle, connecting plate, locking block, and spring, uses the second positioning pin as a fulcrum to achieve stable driving of the moving parts, resulting in high transmission efficiency. The concave-convex teeth and curved block design on the end face of the locking block increases the friction with the glue strip, ensuring that the glue strip can be stably pushed and avoiding slippage, thereby ensuring uniform glue dispensing and improving the performance.

[0021] 3. In the glue gun of this utility model, the glue guiding structure is stable: the track design inside the glue guiding part makes the movement of the moving parts in the glue guiding channel more stable and smooth, reduces the resistance in the glue strip transmission process, effectively prevents the glue strip from getting blocked in the transmission process, and improves work efficiency.

[0022] 4. The glue gun of this utility model has a reliable melting structure: the heating structure of the melting section can quickly melt the glue strip, ensuring the continuity and uniformity of glue dispensing, and meeting the needs of different application scenarios.

[0031] Example 1: The specific structure of this utility model is as follows:

[0032] Please refer to the appendix. Figure 1-5 This utility model discloses a glue gun with a trigger structure and a detachable battery structure. The glue gun includes a cover that is connected to the outer shell. The outer shell is composed of two cover pieces that can be connected together. The glue inlet end inside is provided with a glue strip guide block 41. The glue strip guide block 41 has a glue inlet channel. The glue strip 5 enters straight through the glue inlet channel. A movable part 42 is provided inside the outer shell and is located in the glue outlet direction of the glue strip guide block 41. The movable part 42 has a glue guide channel. The glue guide channel and the glue inlet channel are straight through each other and form a glue guide channel.

[0033] The glue gun includes a power supply unit 1, a glue guiding unit 4 angled to the power supply unit 1, and a glue melting unit 3 located in the glue dispensing direction of the glue guiding unit 4. The glue melting unit 3 has a glue melting channel and a glue dispensing nozzle located at the outer end of the glue melting channel. The battery 11 inside the power supply unit 1 is a detachable structure. The detachable structure includes a cover 12, which can be fastened and fixed to the battery inlet at the tail end of the power supply unit 1. The glue melting unit 3 is equipped with a heating structure.

[0034] like Figure 5 As shown, the cover 12 has a front cover and a side cover 121 perpendicular to the front cover. The side cover 121 is provided with a spring key 122 and a Type-C charging interface 124. A hook end 123 is connected to the spring key 122 and is used to engage with the right-angle step at the opening of the power supply section 1. The spring key 122 is reset by a spring. When the spring key 122 is pressed down, the hook end 123 can be disengaged from the right-angle step. The cover 12 has a contact charging terminal inside, which is connected to the Type-C charging interface 124. The contact charging terminal can also abut against the charging terminal of the battery 11. The battery 11 is provided with a battery casing 111.

[0035] The adhesive guiding part 4 has an adhesive guiding channel inside, which is linearly connected to the melt adhesive channel. The adhesive guiding channel has a movable part 42 that can reciprocate in the adhesive guiding direction. This movable part 42 has an adhesive channel for the adhesive strip to pass through and a lower opening. Figure 3 As shown, the upper part of the movable part 42 is an arched cavity, which is the glue channel. The glue strip needs to move through the glue channel towards the melt channel of the melt section 3. The glue guiding part 4 is provided with a track, and the movable part 42 slides on the track.

[0036] A trigger structure 2 is provided at the corner between the power supply unit 1 and the adhesive guiding unit 4. The trigger structure 2 includes:

[0037] The locking block 23 has its first end extending from the lower opening into the adhesive channel inside the movable member 42. When the locking block 23 moves, it can drive the movable member 42 to move. The locking block 23 has a toothed surface 231 at its first end. The locking block 23 is a curved block, specifically, the locking block 23 has an arc-shaped structure.

[0038] Spring 24, one end of which is sleeved in the first positioning post 43 inside the guide rubber part 4, and the other end is connected to the locking block 23 to form a reset mechanism;

[0039] Connecting plate 22, the first end of which is rotatably connected to the second end of locking block 23; the connecting plate 22 is a straight panel;

[0040] The trigger handle 21 has its inner end rotatably connected to the second end of the connecting plate 22, and its outer end extends out of the guide rubber part 4. The handle of the trigger handle 21 can also be rotatably connected to the second positioning post in the power supply part 1, so that the trigger handle 21 can rotate with the second positioning post as a fulcrum, thereby pulling the connecting plate 22 to move.

[0041] Example 2:

[0042] The following is the working principle of this glue gun:

[0043] A trigger structure is provided at the corner between the power supply section 1 and the adhesive guiding section 4. The inner end of the trigger handle 21 is rotatably connected to the second end of the connecting plate 22, and the outer end extends out of the adhesive guiding section 4. Its handle is rotatably connected to the second positioning post inside the power supply section 1, and rotates with the second positioning post as a fulcrum. When the trigger handle 21 is pressed, the connecting plate 22 is pulled to move, and the connecting plate 22 drives the locking block 23 to move. The first end of the locking block 23 extends from the lower opening of the movable member 42 into the adhesive channel, driving the movable member 42 to move in the adhesive guiding direction. At the same time, the connecting structure formed by the trigger structure enables the grooves 231 on the locking block 23 to lock the adhesive strip 5 and push the adhesive strip forward.

[0044] One end of the spring 24 is sleeved on the first positioning post 43 inside the adhesive guiding part 4, and the other end is connected to the locking block 23. When the trigger handle 21 is released, the serrated teeth 231 release the adhesive strip 5, and the spring 24 resets the locking block 23 and the moving part 42. The adhesive strip 5 enters the molten adhesive channel through repeated pushing.

[0045] The melting section 3 is located in the dispensing direction of the guiding section 4, and has a melting channel and a dispensing nozzle. It has an internal heating structure that can quickly melt the pushed adhesive strip 5 and extrude it from the dispensing nozzle. The preheating time of the heating section of the heating structure is less than 15 seconds, that is, the heating section can quickly dispense adhesive within 15 seconds, improving efficiency and preventing adhesive dripping during dispensing.

[0046] In summary, the battery in this glue gun is designed to be detachable: the detachable structure of the battery in the power supply section is fixed by the snap-fit ​​of the cover and the battery inlet, which makes it convenient for users to quickly replace the battery when the battery is depleted, without having to replace the entire glue gun, thus reducing the cost of use and improving the convenience and endurance of the glue gun.

[0047] In this glue gun, the trigger structure enables efficient reset: the unique trigger structure, through the coordinated work of the trigger handle, connecting plate, locking block, and spring, uses the second positioning pin as a fulcrum to achieve stable driving of the moving parts, resulting in high transmission efficiency. The concave-convex teeth and curved block design on the end face of the locking block increases the friction with the glue strip, ensuring that the glue strip can be stably pushed and avoiding slippage, thereby ensuring uniform glue dispensing and improving the performance.

[0048] In this glue gun, the glue guiding structure is stable: the track design inside the glue guiding part makes the movement of the moving parts in the glue guiding channel more stable and smooth, reduces the resistance during glue strip transmission, effectively prevents glue strip blockage during transmission, and improves work efficiency.

[0049] In the glue gun of this invention, the melting structure is reliable: the heating structure of the melting section can quickly melt the glue strip, ensuring the continuity and uniformity of glue dispensing, and meeting the needs of different application scenarios.
