Description

Technical Field

[0001] The utility model relates to the technical field of hot air guns, in particular to a detachable hot air gun. Background Art

[0002] A hot air gun is a heating tool used to heat air to form a hot air flow and has multiple functions.

[0003] Specifically, hot air guns can be used to remove old paint from metal surfaces, remove self-adhesive stickers, heat plastic hoses to bend them, dry damp wood, heat to shrink packaging film and packaging tubes, remove rust, heat to shrink polyethylene used to connect metals, and heat to soften welds. The hot air flow blown out from the gun core of the heating resistor wire can also be used to weld or remove components.

[0004] Hot air guns are generally powered by a power cord. The power cord makes the hot air temperature discharged by the hot air gun high enough and the working effect is good. However, the hot air gun will be entangled by the power cord when working, and the operating distance is also affected by the length of the power cord. Sometimes when working outdoors, it is difficult to find a socket and cannot operate.

[0005] Therefore, DC heat guns powered by battery packs were developed. Compared with the power supply method via power cord, DC heat guns are simpler and more convenient to use. However, the heat gun body and handle of existing DC heat guns are integrally formed. If there is a problem with the internal heat gun body, such as the heating wire or the handle, and repair is required, the heat gun will not work properly or the entire heat gun will need to be replaced, resulting in high purchase costs.

[0006] Therefore, in the present utility model patent application, the applicant has carefully studied a detachable hot air gun to solve the above problems. Utility Model Content

[0052] In this embodiment, the blowing unit 30 includes a motor 31 and a fan installed at the output end of the motor 31. The motor 31 and the fan are both disposed within the air gun main housing 10. When the motor 31 is powered on, the fan rotates to bring external air to the heating unit 40, where the air is heated.

[0053] The heating assembly includes a wind tube and a heating wire 41 disposed in the wind tube. The wind tube is disposed in the air gun main housing 10 and is located on the air outlet side of the fan blades of the blowing unit 30 .

[0054] The air gun main housing 10 has two first conductive terminals 11, and the blowing unit 30 and the heating unit 40 are electrically connected to the two first conductive terminals 11;

[0055] The handle 20 has two second conductive terminals 21 for connecting to a power source 60 .

[0056] The air gun main housing 10 is connected to the handle 20 , and the first conductive terminal 11 and the second conductive terminal 21 allow the power supply 60 to supply power to the blowing unit 30 and the heating unit 40 .

[0057] In this embodiment, the lower end surface of the air gun main housing 10 is recessed upwardly with a first recess 12 for receiving the upper end of the handle 20. The inner front side wall of the first recess 12 is recessed outwardly with a latching groove 13. Two first conductive terminals 11 are protruding from the inner top wall of the first recess 12.

The sliding block 512 and the clamping member body 511 are both slidably mounted in the upper end portion of the handle 20 that extends into the first groove 12. One end of the clamping member body 511 can extend or retract from the front side of the upper end portion of the handle 20 that extends into the first groove 12, so as to be engaged with and disengaged from the clamping slot 13.

[0063] One end of the sliding block 512 is connected to the other end of the clip body 511. The clip body 511 slides along with the sliding block 512. The other end of the elastic member 52 abuts against the sliding block 512, so that the sliding block 512 drives the clip body 511 to extend out of the handle 20.

[0064] The other end of the sliding block 512 is connected to the first wedge block 513, and the button 53 is provided with a second wedge block 531. The second wedge block 531 and the first wedge block 513 form an inclined surface together. When the button 53 slides downward, the second wedge block 531 pushes the first wedge block 513 to slide horizontally, thereby driving the clip body 511 to retract into the upper end part of the handle 20 that extends into the first groove 12.

[0065] Preferably, the first wedge block 513 is provided with a first inclined surface 514 , which is arranged toward the protruding end of the clamp body 512 , and the second wedge block 531 is provided with a second inclined surface 532 , which is arranged parallel to the first inclined surface 514 .

Next, the upper end of the handle 20 is inserted into the first groove 12 of the air gun main housing 10, and the first conductive terminal 11 is inserted into the second groove 22. At this time, simply release the button 53. Under the reset action of the elastic member 52, the sliding block 512 drives the clip body 511 to extend out of the handle 20 and into the corresponding groove 13 of the air gun main housing 10, thus completing the assembly.

[0070] When the handle 20 needs to be disassembled, the handle 20 can be separated by simply pressing the button 53 .

[0071] The key points of the design of this utility model are that the main housing of the air gun and the handle are detachably connected by pressing an elastic locking assembly, which is easy to assemble. No matter which of the main housing of the air gun or the handle needs repair, the corresponding one can be replaced and used normally without affecting normal use, and the purchase cost is low. At the same time, different types of handles can be used in combination according to different usage requirements.

[0072] Secondly, the specific structural design of the pressing elastic locking component improves the efficiency of disassembly and assembly. In addition, the overall structural design is ingenious and reasonable, and the assembly between the components is convenient and firm, ensuring stability and reliability during use.

[0073] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention.
