Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 - Figure 4 , a dust and sand proof electromagnetic induction heater shown in the figure comprises a handheld heater body 1, a docking interface is provided on the handheld heater body 1, and a docking cap 2 plugged into the docking interface of the handheld heater body 1, a locking portion 3 is installed on the docking cap 2, and the installation locking between the docking cap 2 and the handheld heater body 1 is realized by the locking portion 3, and the docking cap 2 is provided with two sockets 4; and a heating copper wire 5 that slides through the two sockets 4, and the bottom of the heating copper wire 5 is plugged into the handheld heater body 1; and a clamping portion 6 installed in the docking cap 2, and the clamping and positioning of the heating copper wire 5 is realized by the clamping portion 6; and a dust removal component 7 installed in the docking cap 2, and the dust and sand attached to the outside of the heating copper wire 5 is cleaned by the dust removal component 7;

[0028] In this solution, the heating copper wire 5 is inserted into the socket 4 and clamped and positioned by the clamping part 6. When the personnel then inserts the docking cap 2 onto the handheld heater body 1, the bottom of the heating copper wire 5 docks with the handheld heater body 1. At the same time, in actual operation, the vibration of the heating copper wire 5 is achieved through the change in the shape of the clamping part 6 and the combined action of the dust removal component 7, thereby effectively removing the dust and sand particles attached to the outside thereof, avoiding the residual particles and affecting its normal heating operation.

[0029] For further information, see Figure 2 - Figure 4 and Figure 6 The clamping part 6 includes a clamping rod 8 rotatably mounted on the inner wall of the docking cap 2, a docking member 9 is mounted on the clamping rod 8, a clamping plate 10 abutting against the outer side of the heating copper wire 5 is fixed on the docking member 9, and a driving member 11 for driving the clamping rod 8 to rotate is fixed on the inner wall of the docking cap 2;

[0030] Among them, see Figure 3 - Figure 5The docking member 9 includes an inner rod 12 fixed to the outside of the clamping rod 8, a sleeve 13 is rotatably sleeved on the outside of the inner rod 12, the clamping plate 10 is fixed to the outside of the sleeve 13, a notch 14 is provided on the inside of the sleeve 13, a mounting opening 15 is provided on the outside of the inner rod 12, a block 16 abutting against the notch 14 is slidably installed in the mounting opening 15, a spring sheet 17 fixed to the block 16 is fixed in the mounting opening 15, the notch 14 is designed to be tooth-shaped, and the outside of the block 16 is an arc-shaped structure, and under the action of external force, the block 16 will be separated from the notch 14;

[0031] At the same time, the driving member 11 includes a driving motor 18 fixed on the inner wall of the docking cap 2, and driving gears 19 are installed on the inner wall of the docking cap 2 and the outer end of the output end of the driving motor 18. The two driving gears 19 are meshed with each other for transmission. Transmission gears 20 are fixed on the outer sides of the two clamping rods 8, and the two transmission gears 20 are respectively meshed with the outer sides of the two driving gears 19.

[0032] In this solution, the principle of the clamping part 6 clamping the heating copper wire 5 is:

[0033] First, by driving the motor 18, the two driving gears 19 are synchronously reversed, so that the two transmission gears 20 meshing therewith are synchronously reversed, so that the two clamping rods 8 are synchronously rotated in the opposite direction, thereby driving the inner rod 12 to rotate, and under the action of the spring sheet 17, the block 16 is abutted against the notch 14, and then the outer sleeve 13 is rotated accordingly, so that the two clamping plates 10 clamp the heating copper wire 5 and abut against each other for positioning;

[0034] It should also be noted that by reversing the driving motor 18, the other end of the clamping plate 10 will be clamped against the heating copper wire 5. At the same time, the driving motor 18 continues to rotate, which will continue to drive the driving gear 19 to rotate. Under the action of the transmission gear 20, the clamping rod 8 and the inner rod 12 continue to rotate. Under the action of external force, the block 16 will squeeze the spring sheet 17 and disengage from the recess 14, so that the inner rod 12 continues to rotate, while the outer sleeve 13 stops rotating and remains in a state of abutting against the heating copper wire 5, which is convenient for dust removal operations on the heating copper wire 5.

[0035] For further information, see Figure 7 and Figure 8 The dust removal component 7 includes a slide bar 29 fixed on the inner wall of the docking cap 2, a movable plate 30 is slidably sleeved on the outer side of the slide bar 29, an adjustment frame 31 is fixed to the bottom of the movable plate 30, an adjustment member 32 connected to the adjustment frame 31 is installed between two adjacent clamping rods 8, and an adjustment sheet 33 is fixed to the outer side of the movable plate 30;

[0036] The adjusting member 32 includes a connecting plate 34 fixed to the outside of the clamping rod 8 , a roller 35 is rotatably mounted between the two connecting plates 34 , and the roller 35 is slidably inserted in the adjusting frame 31 .

[0037] In this solution, the principle of dust removal for the heating copper wire 5 is:

[0038] First, by driving the motor 18 to rotate, the bottom of the clamping plate 10 is abutted against the outside of the heating copper wire 5. Then, by continuing to rotate the driving motor 18, the clamping rod 8 is rotated, driving the connecting plate 34 fixed at its outer end to rotate, and causing the roller 35 to make a circular motion along the clamping rod 8. When the roller 35 makes a circular motion, it moves along the adjusting frame 31, thereby driving the adjusting frame 31 and the moving plate 30 to reciprocate along the slide bar 29, and driving the adjusting plate 33 to reciprocate through the heating copper wire 5, and the heating copper wire 5 is moved to vibrate, so that the dust particles and other debris remaining on the outside of the heating copper wire 5 can be effectively vibrated off, so that the subsequent heating effect of the metal product is better.

[0039] After the heating copper wire 5 is vibrated and dusted, the driving motor 18 rotates in the reverse direction, driving the other end of the clamping plate 10 to abut against the outer side of the heating copper wire 5, thereby positioning the heating copper wire 5.

[0040] Example 2: Please refer to Figure 1 - Figure 3 and Figure 5 This embodiment further explains the first embodiment, and the difference lies in that one embodiment of the locking portion 3 between the docking cap 2 and the handheld heater body 1 is disclosed.

[0041] Specifically, the locking portion 3 includes a fitting sleeve 21 fixed to the outside of the docking cap 2, a convex opening 22 is provided in the fitting sleeve 21, a locking protrusion 23 is inserted in the convex opening 22, a locking groove 24 adapted to the locking protrusion 23 is provided on the outside of the handheld heater body 1, and an abutting piece 25 abutting against the outside of the locking protrusion 23 is installed on the outside of the fitting sleeve 21;

[0042] The abutting member 25 includes an abutting sleeve 26 which is slidably sleeved on the outside of the fitting sleeve 21. The outside of the fitting sleeve 21 is sleeved with an extrusion spring 27 for pushing the abutting sleeve 26 downward. A limiting ring 28 which is fixed to the outside of the fitting sleeve 21 and limits the bottom of the abutting sleeve 26;

[0043] In this solution, when installing the docking cap 2, the personnel align the docking cap 2 with the docking port on the handheld heater body 1 and insert it. When inserting, the fitting sleeve 21 on the outside of the docking cap 2 will move along the outside of the handheld heater body 1, and make the locking protrusion 23 dock with the locking groove 24, and under the action of the extrusion spring 27, the abutting sleeve 26 moves down, abutting the outer ends of the locking protrusion 23, so that the locking protrusion 23 and the locking groove 24 are stably engaged, so as to achieve stable insertion and docking of the docking cap 2 and the handheld heater body 1;

[0044] It should also be noted that in order to facilitate the movement of the abutting sleeve 26, anti-slip grooves are provided on the outside of the abutting sleeve 26. At the same time, in order to facilitate the docking between the locking protrusion 23 and the locking groove 24, rounded corners are provided on the outside of the locking protrusion 23, and the bottom of the abutting sleeve 26 is provided with a chamfer that matches the locking protrusion 23.

[0045] During the subsequent disassembly, the personnel only need to push the fitting sleeve 21 upwards to make the fitting sleeve 21 disengage from the locking protrusion 23. At the same time, since there is a magnetic block that is magnetically attracted to each other between the convex opening 22 and the locking protrusion 23, the locking protrusion 23 will move in the convex opening 22 and disengage from the locking groove 24 under the action of the magnetic block after there is no limitation of the fitting sleeve 21, thereby completing the disassembly of the docking cap 2 and the handheld heater body 1.
