[0009] According to the above technical solution, the knocking device includes an inclined block, a knocking plate, a return spring and a fixed plate, and the inclined block is fixedly connected to the outer wall of the bottom surface of the clamping claw.
[0010] According to the above technical solution, the fixing plate 1 is fixedly connected to the inner wall of the protective shell.
[0011] According to the above technical solution, the outer wall of the top surface of the fixed plate 1 is fixedly connected to a return spring 1, and the other end of the return spring 1 is fixedly connected to a knocking plate. The top of the knocking plate is provided with an inclined groove, and the inclined block is arranged in the inclined groove.
[0012] According to the above technical solution, the blowing device includes an extrusion column, an extrusion block, a limit plate, a second fixed plate, a second return spring, a protrusion, a rotating shaft, a rotating groove, a fixed shaft sleeve, a connecting rod, a third return spring, a single-sided inclined block, a limit sleeve, a limit block, a short shaft, and a fan blade.

[0014] The present invention provides an induction heating device having the following beneficial effects:
[0015] (1) The present invention provides a clamping device. When the extended nozzle needs to be heated, the extended nozzle is placed in the heating coil. At this time, the bolt head is twisted to move the bolt rod through the screw hole in the threaded plate, and the clamping claw moves together.

[0016] (2) The present invention sets a knocking device. When the clamping claw moves left and right, it drives the inclined block fixed at the bottom of the clamping claw to move together. At this time, the inclined block will squeeze the inclined groove on the knocking plate. The knocking plate moves toward the reset spring under the pressure of the inclined block, completing a knock on the heating coil. When the inclined block leaves the inclined groove, the reset spring resets and drives the knocking plate to reset. There are multiple groups of inclined grooves on the knocking plate. Therefore, when the clamping claw moves left and right, it will knock the heating coil multiple times to achieve a shaking effect, knocking off the dust and oxide layer on the heating coil, preventing the heating efficiency of the heating coil from being reduced due to dust and oxide layer.
[0017] (3) The present invention provides an air blowing device, which drives the fan blades to rotate by linkage with the knocking device. When the knocking device knocks off the dust and oxide layer on the surface of the heating coil, it will be left inside the protective shell. If it is not cleaned for a long time, it will affect the heating effect of the heating coil and also affect the instruments in the equipment. By blowing away the dust and oxide layer in the protective shell in time, it not only protects the instruments but also improves the heating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0029] See also Figures 1-9 , one embodiment of the present invention is: an induction heating device, comprising a workbench 1, a high-frequency heater 2 is fixed to the top outer wall of the workbench 1, a plug 3 is provided at the input end of the high-frequency heater 2, a heating coil 4 is provided at the output end of the high-frequency heater 2, a protective shell 6 is fixedly connected to the outer wall of the high-frequency heater 2, an extended nozzle 5 is provided on the inner wall of the heating coil 4, the outer wall of the protective shell 6 is fixedly connected to a clamping device 7 for fixing the workpiece, wherein the clamping device 7 comprises a clamping claw 71, a threaded rod 72, a connecting plate 73, a threaded plate 74 and a bolt head 75; the connecting plate 73 is fixedly connected to the top outer wall of the protective shell 6, the outer wall of the connecting plate 73 is fixedly connected to the threaded plate 74, a screw hole is provided on the threaded plate 74, and the threaded rod 72 is threadedly passed through the screw hole, one end of the threaded rod 72 is fixedly connected to the clamping claw 71, and the other end of the threaded rod 72 is fixedly connected to the bolt head 75, the bolt head 75, the threaded rod 72 and the clamping claw 71 are located on the same horizontal line, and are fixedly installed on both sides of the extended nozzle 5.
[0030] When the plug 3 is inserted into the power supply, the high-frequency heater 2 is started, the high-frequency heater 2 heats the heating coil 4, and the heating coil 4 heats the extended nozzle 5, and the heating process is prevented from being disturbed by external factors inside the protective shell 6. At this time, the extended nozzle 5 is clamped and fixed by the clamping device 7, and the threaded rod 72 rotates clockwise synchronously by manually rotating the bolt head 75 clockwise. Because the threaded rod 72 is threadedly connected to the threaded plate 74, the threaded rod 72 moves toward the extended nozzle 5 and drives the clamping claw 71 to move toward the extended nozzle 5 until the extended nozzle 5 is completely clamped to prevent the extended nozzle 5 from shaking during the heating process and affecting the heating efficiency and interfering with the process. When the heating is completed, the bolt head 75 is rotated counterclockwise, and the threaded rod 72 drives the clamping claw 71 to move away from the extended nozzle 5.
[0031] When this example is working: when the extended nozzle 5 needs to be heated, first plug in the power supply of the plug 3, then the high-frequency heater 2 starts to work and heats the heating coil 4, then the extended nozzle 5 is inserted into the heating coil 4, and the bolt head 75 is manually controlled to rotate clockwise, driving the threaded rod 72 to rotate synchronously, and the threaded rod 72 is threadedly connected to the screw hole on the threaded plate 74, so it moves toward the direction of the extended nozzle 5 until the extended nozzle 5 is fixed.
[0032] See also Figures 1-9 On the basis of the above embodiment, another embodiment of the present invention is: the bottom outer wall of the clamping device 7 is fixedly connected to the knocking device 8 for convenient cleaning of the heating coil 4, and the bottom outer wall of the knocking device 8 is fixedly connected to the blowing device 9 for keeping the device clean, wherein the knocking device 8 includes an inclined block 81, a knocking plate 82, a return spring 83 and a fixed plate 84, the inclined block 81 is fixedly connected to the bottom outer wall of the clamping claw 71, the fixed plate 84 is fixedly connected to the inner wall of the protective shell 6, the top outer wall of the fixed plate 84 is fixedly connected with a return spring 83, the other end of the return spring 83 is fixedly connected with the knocking plate 82, the top of the knocking plate 82 is provided with an inclined groove, and the inclined block 81 is arranged in the inclined groove.
[0033] When the clamping device 7 is started, the clamping claw 71 moves left and right, and at the same time drives the inclined block 81 to move synchronously. When the inclined block 81 moves left and right, it will squeeze the inclined groove on the knocking plate 82. When the inclined groove of the knocking plate 82 is squeezed, the knocking plate 82 moves downward under pressure, compressing the reset spring 83 and completing a knock on the heating coil 4. When the inclined block 81 leaves the inclined groove, the reset spring 83 will reset and drive the knocking plate 82 to reset. There are multiple groups of inclined grooves on the knocking plate 82, so when the inclined block 81 moves, it will complete multiple knocks on the heating coil 4.
[0034] The blowing device 9 includes an extrusion column 91, an extrusion block 92, a limiting plate 93, a second fixed plate 94, a second return spring 95, a protrusion 96, a rotating shaft 97, a rotating groove 98, a fixed shaft sleeve 99, a connecting rod 910, a third return spring 911, a single-sided inclined block 912, a limiting sleeve 913, a limiting block 914, a short shaft 915 and a fan blade 916. The extrusion column 91 is fixedly connected to the outer wall of the bottom surface of the knocking plate 82. The bottom of the extrusion column 91 is provided with an extrusion block 92. The interior of the extrusion block 92 passes through the limiting plate 93, and the extrusion block 92 is slidably installed on the limiting plate 93. The outer wall of the limiting plate 93 is fixedly connected to the second fixed plate 94. The side of the second fixed plate 94 is fixedly connected to the second return spring 95. The other end of the second return spring 95 is fixedly connected to the extrusion block 92. The bottom of the extrusion block 92 The outer wall of the surface is fixedly connected with a protrusion 96, and the bottom surface of the extrusion block 92 is fitted with a rotating shaft 97. A rotating groove 98 is provided on the outer wall of the rotating shaft 97, and the inner wall of the rotating groove 98 is slidably connected with the protrusion 96. The outer wall of the rotating shaft 97 is fixedly connected with a fixed shaft sleeve 99, and the outer wall of the fixed shaft sleeve 99 is fixedly connected with a connecting rod 910. The other end of the connecting rod 910 is fixed to the top inner wall of the protective shell 6. A groove is provided on the rotating shaft 97, and a return spring three 911 is fixedly connected in the groove. The other end of the return spring three 911 is fixedly connected to a single-sided inclined block 912. A limiting sleeve 913 is provided on the outer wall of the rotating shaft 97. The inner wall of the limiting sleeve 913 is fixedly connected to the limiting block 914. The outer wall of the limiting sleeve 913 is fixedly connected with a short shaft 915, and the outer wall of the short shaft 915 is fixedly connected with a fan blade 916.
[0035] The blowing device 9 drives the fan blades 916 to rotate by linkage with the knocking device 8. When the knocking device 8 knocks off the dust and oxide layer on the surface of the heating coil 4, it will be left inside the protective shell 6. If it is not cleaned for a long time, it will affect the heating effect of the heating coil 4 and also affect the instruments in the equipment. Therefore, a blowing device 9 is provided to blow away the dust and oxide layer in the protective shell 6 in time, which not only protects the instruments but also improves the heating efficiency.
[0036] When this embodiment is working: when the clamping claw 71 moves left and right, it drives the inclined block 81 fixed at the bottom of the clamping claw 71 to move together. At this time, the inclined block 81 will squeeze the inclined groove on the knocking plate 82, and the knocking plate 82 moves toward the reset spring 83 under the pressure of the inclined block 81, completing a knock on the heating coil 4. When the inclined block 81 leaves the inclined groove, the reset spring 83 resets and drives the knocking plate 82 to reset. There are multiple groups of inclined grooves on the knocking plate 82, so when the clamping claw 71 moves left and right, it will knock the heating coil 4 multiple times to achieve the shaking effect, knock off the dust and oxide layer on the heating coil 4, and prevent the heating efficiency of the heating coil 4 from being reduced due to dust and oxide layer.
[0037] When the knocking plate 82 knocks up and down, it drives the extrusion column 91 to reciprocate up and down, and the extrusion column 91 squeezes the extrusion block 92, and the extrusion block 92 is limited by the limit plate 93, moves in the direction away from the extrusion column 91, and drives the protrusion 96 to move synchronously, and the protrusion 96 is slidably connected to the rotation groove 98 on the rotating shaft 97. The rotating shaft 97 rotates in the direction of the rotation groove 98 under the pressure of the protrusion 96, and the rotating shaft 97 rotates and is connected to the inner wall of the fixed shaft sleeve 99, and the fixed shaft sleeve 99 is fixedly connected to the connecting rod 910, so that the rotating shaft 97 cannot move and can only rotate. When the rotating shaft 97 rotates, it drives the single-sided inclined block 912 to rotate. When the single-sided inclined block 912 rotates in the opposite direction of its inclined surface, it is limited by the limit block 914 and cannot compress the return spring 3 911 to enter the groove, thereby driving the limit sleeve 913 to rotate together, and the limit sleeve 913 drives the short shaft 915 fixed on its outer wall to rotate together, and the short shaft 915 drives the fan blade 916 to rotate to complete the blowing effect;
[0038] When the extrusion column 91 leaves the extrusion block 92, the extrusion block 92 is reset by the action of the reset spring 2 95, and the protrusion 96 drives the rotating shaft 97 to rotate counterclockwise along the rotating groove 98, and the rotating shaft 97 drives the single-sided inclined block 912 to rotate counterclockwise. When rotating counterclockwise, the inclined surface of the single-sided inclined block 912 is squeezed to the limit block 914, and moves into the groove to compress the reset spring 3 911. Because the single-sided inclined block 912 enters the groove, it cannot drive the limit sleeve 913 by squeezing, and the short shaft 915 cannot rotate the fan blade 916 to stop rotating. Therefore, the fan blade 916 only rotates in one direction. The fan blade 916 rotates only when the extrusion column 91 squeezes the extrusion block 92, and stops rotating when leaving. Therefore, the reciprocating motion of the extrusion column 91 will only drive the fan blade 916 to rotate in one direction.
[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
