[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: Figure 1-8As shown, the magnet single-sided mounted heating plate includes a magnetic strip 1, a magnetic ring 2, a coil 3 and a bracket 4. The coil 3 is arranged on the top surface of the bracket 4, and the bottom surface of the bracket 4 is provided with a magnetic ring groove 401 for accommodating the magnetic ring 2 and a magnetic stripe groove 402 for accommodating the magnetic strip 1. The magnetic ring groove 401 is an annular groove arranged at the center position of the bracket 4, the magnetic ring 2 is an annular magnet accommodated in the magnetic ring groove 401, and the magnetic stripe groove 402 extends from the magnetic ring groove 401 toward the outer edge of the bracket 4. The utility model provides a heating plate with a single-sided magnet installation, so as to solve the problem that the magnetic component 1 and the magnetic component 2 of the existing heating plate are separately arranged on the top surface and the bottom surface of the bracket, and the magnetic component 1 needs to be assembled on the top surface of the bracket and the bracket can be turned over to install the magnetic component 2 after the glue is dried thoroughly during the assembly process, the assembly steps are complicated, the assembly time is long, and the assembly efficiency is low. The utility model mainly provides a magnetic ring groove 401 for accommodating the magnetic ring 2 and a magnetic stripe groove 402 for accommodating the magnetic stripe 1 on the bottom surface of the bracket 4, so that the magnetic ring 2 and the magnetic stripe 1 are arranged on the same side of the bracket 4, so as to realize the synchronous assembly of the magnetic stripe 1 and the magnetic ring 2, and there is no need to wait for the glue for fixing one of the magnetic components on the bracket to dry thoroughly before assembling the other magnetic component, so as to simplify the assembly steps and save assembly time, and the assembly efficiency is high. Compared with the existing magnetic ring groove and magnetic ring composed of a plurality of arc segments arranged at intervals, the magnetic ring groove 401 is configured as an annular groove, and the magnetic ring 2 is configured as an annular magnet, so as to improve the magnetic field strength and effectively improve the power of the heating plate. Specifically, the magnetic strip 1 and the magnetic ring 2 are made of magnetic material, and the coil 3 is wound by copper wire or aluminum wire. The heating disk using the above structure can still achieve the power of the existing heating disk by replacing the material of the coil 3 from copper wire to aluminum wire, and replacing the material of the magnetic strip 1 and the magnetic ring 2 from high-permeability magnets to ordinary magnets, thereby effectively reducing the production cost.

[0030] In the embodiment of the utility model, the magnetic stripe groove 402 is connected with the magnetic ring groove 401 through the connecting port 403, and a part of the magnetic stripe 1 extends into the magnetic ring groove 401 through the connecting port 403 and is relatively located up and down with the magnetic ring 2 to restrict the magnetic ring 2 from moving away from the magnetic ring groove 401. Since the magnetic stripe groove 402 is connected with the magnetic ring groove 401, a part of the magnetic stripe 1 extends into the magnetic ring groove 401 to restrict the magnetic ring 2 from moving away from the magnetic ring groove 401, thereby improving the assembly stability of the magnetic ring 2, and at the same time increasing the area of ​​the magnetic stripe 1 to improve the power of the heating disk.

[0031] In the embodiment of the utility model, the end of the magnetic strip 1 away from the outer edge of the bracket 4 abuts against the inner ring wall of the magnetic ring groove 401. Since the end of the magnetic strip 1 away from the outer edge of the bracket 4 abuts against the inner ring wall of the magnetic ring groove 401, the area of ​​the magnetic strip 1 is increased while the assembly stability of the magnetic ring 2 is improved.

[0032] In the embodiment of the utility model, the inner ring wall of the magnetic ring groove 401 is formed with a sunken shoulder 404 which abuts against the end of the magnetic strip 1 away from the outer edge of the bracket 4, the bottom of the magnetic strip groove 402 and the sunken shoulder 404 are located on the same horizontal plane, and the part of the magnetic strip 1 extending into the magnetic ring groove 401 abuts against the magnetic ring 2 up and down. The above arrangement provides good assembly stability for the magnetic strip 1 by arranging the sunken shoulder 404 which abuts against the end of the magnetic strip 1 away from the outer edge of the bracket 4 on the inner ring wall of the magnetic ring groove 401, thereby preventing the end of the magnetic strip 1 away from the outer edge of the bracket 4 from moving toward the magnetic ring 2 and causing breakage.

[0035] In the embodiment of the utility model, the lead wire slot 406 is provided with a limit buckle 400 at its slot. The above arrangement provides the limit buckle 400 at the slot of the lead wire slot 406, so that the wire leading the coil 3 to the lead wire slot 406 is assembled stably.
