[0031] Example 1

[0032] This specific embodiment is a handheld induction heater, the structural schematic diagram of which is shown below. Figures 1-8 As shown, the handheld induction heater includes a heater body 1, a heat sink 2 installed inside one end of the heater body 1, a mounting hole 3 opened inside the heat sink 2, and an elastic pin 4 slidably installed inside the heat sink 2. A housing 5 is installed at one end of the heater body 1 and sleeved outside the heat sink 2. A limiting component 6 is between the housing 5 and the heat sink 2. The limiting component 6 can squeeze and fix the induction heating coil.

[0033] See Figure 1 , Figure 6 , Figure 7 The heat sink 2 has a pin hole that matches the elastic pin 4 inside, and the pin hole is connected to the mounting hole 3. There are two mounting holes 3, and two pin holes and two elastic pins 4 are provided. There are also two limiting components 6. The two limiting components 6 respectively squeeze the two elastic pins 4. The two elastic pin holes are respectively connected to the two mounting holes 3. The two elastic pins 4 are respectively slidably installed inside the elastic pin holes. When the two access ends of the heating coil are respectively inserted into the two mounting holes 3, they are pressed and fixed by the two elastic pins 4.

[0034] In embodiment 1, the limiting component 6 includes a housing 601 slidably mounted on the housing 5 and an arched piece 602 fixedly mounted on the inner wall of the housing 601. The housing 5 is integrally formed with the heater body 1, and a through groove 501 for sliding of the arched piece 602 is provided on the housing 5.

[0035] See Figures 1-6 When the two ends of the heating coil are inserted into the two mounting holes 3 respectively, the outer shell 601 is slid towards the heater body 1. During the sliding process, the outer shell 601 can drive the arched piece 602 to move synchronously. During the movement, the arched piece 602 continuously contacts the elastic pin 4. The elastic pin 4 initially contacts the bottom of the arched piece 602. During the sliding process of the arched piece 602 towards the heater body 1, the arched piece 602 will continuously squeeze the elastic pin 4, pressing the elastic pin 4 from the pin hole into the mounting hole 3. When the highest point of the arched piece 602 contacts the elastic pin 4, the elastic pin 4 presses the end of the heating coil into the mounting hole 3, thus completing the fixing of the heating coil.

[0036] See Figure 2 as well as Figure 5 , Figure 6 , Figure 7 , Figure 8 Similarly, during disassembly, the elastic pin 4 initially contacts the highest point of the arched plate 602. It is only necessary to slide the outer shell 601 away from the heater body 1. During the sliding process, the outer shell 601 can drive the arched plate 602 to move synchronously. During the movement, the arched plate 602 will release the pressure on the elastic pin 4, thereby releasing the elastic pin 4 from fixing the heating coil.

[0037] No external tools are needed during the entire installation and disassembly process, making the installation and disassembly of the heating coil convenient and quick, and allowing for disassembly and assembly even when tools are unavailable.

[0038] See Figure 2 as well as Figure 5 , Figure 6 ,Figure 7 , Figure 8 An annular slider is fixedly installed on the inner wall of the outer shell 601, and an annular groove 603 that cooperates with the annular slider is opened on the outer surface of the shell 5. The outer shell 601 is slidably installed on the shell 5 through the cooperation of the annular slider and the annular groove 603. The cooperation of the annular slider and the annular groove 603 can guide the sliding of the outer shell 601.

[0039] See Figure 1 The outer surface of the outer shell 601 has at least one groove 604. Under the action of at least one groove 604, the user's finger can be placed, so that the user can easily hold the outer shell 601 and slide it.

[0040] In addition, in this embodiment 1, see Figure 8 The arched piece 602 has a T-shaped structure. The annular slider surface of the outer shell 601 is provided with a first mounting groove 6011 for mounting the arched piece 602. The first mounting groove 6011 is provided with first mounting tracks 6012 on both sides for the arched piece 602 to enter from both sides. The first mounting groove 6011 is also provided with a first limiting groove 6013 for limiting the tail end of the arched piece 602.

[0041] The first mounting track 6012 is designed to facilitate the installation of both sides of the arched piece 602. When both sides of the arched piece 602 enter the first mounting slot 6011 along the first mounting track 6012, the tail end of the arched piece 602 is locked in the first limiting slot 6013, thus completing the installation of the entire arched piece 602. When it is necessary to replace the arched piece 602, simply use a tool or manually pull the tail end of the arched piece 602 out of the first limiting slot 6013, and then pull it out along the first mounting track 6012. The entire installation or disassembly process is very simple and convenient.

[0042] See Figure 7 The elastic pin 4 includes a pin 401, a sliding rod 402 fixedly installed on the side of the pin 401, and a spring 403 fixedly installed on the sliding rod 402. The heat sink 2 has a spring cavity that communicates with the pin hole. The sliding rod 402 is slidably installed inside the spring cavity, and the end of the spring 403 away from the sliding rod 402 is fixedly installed inside the spring cavity.

[0043] During installation, as the arched piece 602 contacts the pin 401 from its bottommost point until its highest point contacts the pin 401, the arched piece 602 presses the pin 401 from the pin hole into the mounting hole 3. Simultaneously, the pin 401 drives the sliding rod 402 to slide inside the spring cavity and press the spring 403.

[0044] During disassembly, as the arched piece 602 contacts the pin 401 from its highest point until its bottom point contacts the pin 401, the arched piece 602 no longer presses against the pin 401. At this time, under the reset action of the spring 403, the sliding rod 402 will slide and reset inside the spring cavity. During the sliding process, the sliding rod 402 can drive the pin 401 to move synchronously and reset to the inside of the pin hole.

[0045] Example 2

[0046] like Figure 9 and Figure 10 , Figure 11 As shown in this embodiment: the housing 5 and the heater body 1 are integrally formed. The housing 5 is provided with a sliding groove 502. The limiting component 6 includes a sliding block 605 that is slidably installed inside the sliding groove 502, a sliding plate 606 that is fixedly installed with the sliding block 605, and an arched piece 602 that is fixedly installed on the side of the sliding plate 606 away from the sliding block 605. The sliding plate 606 is slidably installed inside the housing 5. The two sides of the sliding plate 606 are in contact with the inner wall of the housing 5 and the outer wall of the heat sink 2, respectively.

[0047] During installation, simply push the sliding block 605 inside the groove 502 of the housing 5 towards the heater body 1 to cause the sliding plate 606 to drive the arched plate 602 to press the pin 401. (In this embodiment, the structure of the heat sink 2 is the same as that of the heat sink 2 in embodiment 1, so it can be directly referred to...) Figures 5-6 ); The heating coil connection end is pressed and fixed inside the mounting hole 3;

[0048] See Figure 9 And reference Figures 5-6 During disassembly, simply push the sliding block 605 to move away from the heater body 1 in the groove 502 of the housing 5. This will cause the sliding plate 606 to move the arched piece 602 away from the pin 401. Under the reset action of the spring 403, the pin 401 will be reset from the mounting hole 3 to the inside of the pin hole, thus releasing the fixation of the heating coil connection end and allowing the heating coil to be disassembled.

[0049] For further reference Figures 10-11 The arched piece 602 has a T-shaped structure. The sliding plate 606 has a second mounting slot 6061 for mounting the arched piece 602 on the side away from the sliding block 605. The second mounting slot 6061 has second mounting tracks 6062 on both sides for the two ends of the arched piece 602 to enter. The second mounting slot 6061 is also provided with a second limiting slot 6063 for limiting the tail end of the arched piece 602.

[0050] Similar to Embodiment 1, the second mounting track 6062 is provided in Embodiment 2 to facilitate the installation of both sides of the arched piece 602. When both sides of the arched piece 602 enter the second mounting slot 6061 along the second mounting track 6062, the tail end of the arched piece 602 is locked in the second limiting slot 6063, thus realizing the installation of the entire arched piece 602. At the same time, when it is necessary to replace the arched piece 602, it is only necessary to use a tool or manually pull the tail end of the arched piece 602 out of the second limiting slot 6063, and then pull it out along the second mounting track 6062. The entire installation or disassembly process is very simple and convenient.

[0051] In this application, the arched sheet 602 can be made of a hard and non-deformable metal sheet, as long as the material meets the usage requirements. The improvement in this application only involves the fixing of the heating coil. The internal structure of the heater body 1, the heat sink 2, and how the heater body 1 achieves the heating of the heating coil are not the improvement points of this application. The above are existing technologies and will not be described in detail here.

[0052] In summary, during the installation and disassembly process, the user only needs to use the limiting component 6 to fix and release the heating coil. No external tools are required during the entire installation and disassembly process, making the installation and disassembly of the heating coil convenient and quick, and allowing for installation and disassembly even when tools are unavailable.

[0053] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
