[0014] Further, a plurality of second through holes are arranged on the outside of the heat collecting disc, and a fixing frame is arranged on the outside of the motor.

[0015] Through the above technical scheme, the motor is fixed by the fixing frame, so that the motor will not shake during operation.

[0016] Further, a plurality of clamping grooves are arranged in the blocking plate, and a plurality of clamping blocks corresponding to the clamping grooves are arranged in the heat collecting disc.

[0018] Further, the fan blade and the second limiting ring are elastically connected through a spring, and the first limiting ring and the second limiting ring are provided with intermeshing protrusions.

[0019] By adopting the above technical scheme, the fan blade slowly rotates, drives the second limiting ring to rotate, and simultaneously drives the first limiting ring to synchronously rotate, when the rotating speed of the motor gradually increases, the first limiting ring and the second limiting ring are vertically retracted downwards due to the action, and the first limiting ring is not synchronously rotated.

[0020] Further, the electric heating ring and the motor are electrically connected with external power supply equipment through wires, and the heat collecting disc is internally provided with a cavity matched with the blocking plate.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] An anti-radiation structure for an induction cooker, such as Figures 1-6 As shown, it includes a main body 1, and an electric heating coil 2 with one end extending to the outside is provided inside the main body 1. Multiple sets of first through holes 3 are opened on both sides of the main body 1. The electric heating coil 2 is heated by connecting to an external power supply device through wires. When the internal heat dissipation is carried out, the air blown out by the internal heat dissipation will be discharged to the outside through the multiple sets of first through holes 3 and will not circulate inside.

[0033] For example, the main body 1 is equipped with a motor 11, and the output end of the motor 11 is connected to a fan blade 7. When the heat dissipation is started by the control module 4, the motor 11 starts and the output end drives the fan blade 7 to generate negative pressure, forming a wind that blows towards the heating coil 2, and dissipates the excess heat generated inside through the wind.

[0034] Furthermore, the fan blade 7 is movably connected to a second limiting ring 13. A meshing protrusion is provided between the first limiting ring 12 and the second limiting ring 13. Initially, when the fan blade 7 starts, it rotates slowly. With the meshing protrusions of the first limiting ring 12 and the second limiting ring 13, the fan blade 7 drives the second limiting ring 13 to rotate, simultaneously driving the first limiting ring 12 to rotate synchronously. As the speed of the motor 11 gradually increases, the second limiting ring 13 will retract vertically downwards under the action of 15, causing the first limiting ring 12 and the second limiting ring 13 to no longer mesh, and the first limiting ring 12 to no longer rotate synchronously. 12 and 13 are made of metal.

[0035] In some examples, the fan blade 7 and the second limiting ring 13 are elastically connected by the spring 15, wherein when the rotating speed of the motor 11 gradually increases, the first limiting ring 12 and the second limiting ring 13 are retracted vertically downwards under the action of the spring 15, and the spring 15 is reset when slowly rotating, so that the first limiting ring 12 and the second limiting ring 13 are engaged;

[0036] For example, the heat collecting disc 5 is arranged in the main body 1, and a cavity matched with the blocking plate 9 is formed in the heat collecting disc 5, wherein the first limiting ring 12 is engaged with the blocking plate 9, so that the blocking plate 9 rotates slowly around the first limiting ring 12, the blocking plate 9 is dislocated from the heat collecting disc 5, the through hole formed at the bottom of the heat collecting disc 5 and the through hole formed at the outer side of the heat collecting disc 5 are opened, and the heat collecting disc 5 is communicated with the inside of the main body 1;

[0037] In some examples, a plurality of second through holes 6 are arranged on the outer side of the heat collecting disc 5, and a plurality of clamping blocks 14 corresponding to the clamping grooves 10 are arranged in the heat collecting disc 5, wherein the plurality of clamping grooves 10 arranged on the blocking plate 9 are clamped on the clamping blocks 14 on the heat collecting disc 5 after rotating, and the position of the blocking plate 9 is further limited;

[0038] Further, the heat collecting disc 5 is movably connected with the blocking plate 9, the blocking plate 9 is internally provided with a plurality of clamping grooves 10, wherein the clamping blocks 14 and the clamping grooves 10 are matched to rotate the blocking plate 9, so that the blocking plate 9 does not block the through hole of the heat collecting disc 5, and the excess heat radiation generated by the electric heating ring 2 is eliminated by the fan blade 7 and the motor 11 at the bottom;

[0039] The working principle of the utility model is as follows: when in use, the power is turned on, the electric heating ring 2 is started by the control module 4, and normal use is carried out, when normally used, the heat radiation generated by the electric heating ring 2 to the surrounding is excess heat radiation, under the cooperation of the heat collecting disc 5, the heat radiation emitted by the electric heating ring 2 to the surrounding is reflected and absorbed by the heat insulation material arranged on the heat collecting disc 5, so that the excess heat radiation can be maximized to ensure that the excess heat radiation does not radiate into the main body 1;

[0040] When the use is completed, the electric heating ring 2 is turned off, at this time, the heat dissipation is started by the control module 4, the motor 11 is started, the output end drives the fan blade 7 to generate negative pressure, and the wind blowing to the electric heating ring 2 is formed, when the initial end of the fan blade 7 is started, the fan blade 7 slowly rotates, the first limiting ring 12 and the second limiting ring 13 are matched with the protrusions, the fan blade 7 drives the second limiting ring 13 to actively rotate, and the first limiting ring 12 rotates synchronously, and because the first limiting ring 12 is engaged with the blocking plate 9, the blocking plate 9 rotates slowly around the first limiting ring 12, the blocking plate 9 is dislocated from the heat collecting disc 5, the through hole formed at the bottom of the heat collecting disc 5 and the through hole formed at the outer side of the heat collecting disc 5 are opened, and the heat collecting disc 5 is communicated with the inside of the main body 1;

[0041] When the rotating speed of the motor 11 gradually increases, the first limiting ring 12 and the second limiting ring 13 are not engaged due to the action of the 15, the second limiting ring 13 vertically retracts downwards, and the first limiting ring 12 does not rotate synchronously;

[0042] Specifically, after the multiple sets of clamping grooves 10 arranged on the blocking plate 9 rotate, the clamping grooves 10 are clamped on the clamping blocks 14 on the heat collecting disc 5, and the position of the blocking plate 9 is further limited.

[0043] Through the above structure, the electromagnetic oven can be protected by the heat collecting disc 5, the heat collecting disc 5 can effectively block the radiation, the heat radiation generated inside will not be diffused in a large range and irregularly, and the electronic elements and wires inside the electromagnetic oven can be better protected, and the service life is increased.
