[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Reference Figure 1 to Figure 3. An electromagnetically heated kettle for preventing dry burning, comprising an electromagnetic cooker main body 1, a kettle main body 2 and a liquid level sensor 3, wherein the kettle main body 2 is placed on the electromagnetic cooker main body 1, the kettle main body 2 comprises a kettle body 21 and a tea strainer 22, the tea strainer 22 is located in the kettle body 21, the tea strainer can be detachably connected to the kettle body 21, the tea strainer 22 comprises a cylinder 224, the liquid level sensor 3 is located on the outside of the kettle body 21, a heating plate 221 is provided at the bottom of the cylinder 222, the heating plate 221 is made of a magnetic conductive metal material, the heating plate 221 is arranged corresponding to the electromagnetic cooker main body 1, that is, the electromagnetic cooker main body 1 can electromagnetically heat the heating plate 221, and then heat the liquid in the kettle body 21 through the heating plate 221. Therefore, the heating plate 221 is arranged at the bottom of the kettle body 21, so as to ensure that the electromagnetic cooker main body 1 can act on the heating plate 221 to realize the heating function. Among them, an electromagnetic heating coil disk is provided in the electromagnetic cooker main body 1, which can act with the heating plate 221 during operation to electromagnetically heat the heating plate 221. The material of the heating plate 221 can be martensitic 416 stainless steel, ferritic stainless steel 304 or 316, etc.

[0019] The kettle body 21 is a glass kettle body, the liquid level sensor 3 is fixed on the induction cooker body 1, the liquid level sensor 3 is electrically connected to the controller through a wire, and the controller is electrically connected to the induction cooker body 1 through a wire.

[0020] When the anti-dry-burning electromagnetic heating kettle of the utility model is in use, the liquid level height in the kettle body 21 can be detected by the liquid level sensor 3, and the signal is transmitted to the controller. When the liquid level in the kettle body 21 is very low, the signal of the liquid level sensor 3 is sent to the controller, and the controller controls the electromagnetic cooker body 1 to stop heating to avoid dry-burning. Among them, the liquid level sensor 3 is a liquid level sensor located outside the liquid in the prior art for detecting the liquid level height, such as the liquid level sensor located outside the kettle body 21 in the patent document disclosed in the background technology; the controller is a single-chip microcomputer, which is capable of receiving the signal of the liquid level sensor in the prior art, and can issue corresponding instructions to the corresponding components to continue working or stop working according to the signal.

[0021] The outer circumference of the tea strainer 22 is provided with an integrally formed buckle 222, and the inner wall of the pot body 21 is provided with a hook or a collar, and the buckle 222 cooperates with the hook or the collar. Therefore, when the tea strainer 22 extends into the pot body 21, the buckle 222 is hooked on the hook, and the buckle 222 is limited by the hook. Among them, the buckle 222 is a U-shaped buckle with an opening downward located on the outside of the tea strainer 22, and the hook is directly a protrusion formed in the pot body 21. The U-shaped buckle can be directly inserted into the corresponding protrusion, thereby realizing the positioning of the tea strainer 22 in the pot body 21. The inner diameter of the collar is smaller than the outer diameter of the circumference of the buckle 22. Therefore, when the buckle 222 moves downward to the position of the collar, the collar limits the buckle 22 to prevent the tea strainer 22 from continuing to move downward.

[0022] In one embodiment, the heating sheet 221 and the cylinder 222 are an integrally formed structure, and the heating sheet 221 is the bottom end surface of the tea strainer. Therefore, the heating sheet 221 is a part of the tea strainer 22, and the entire tea strainer 22 is made of a magnetic conductive metal material, so that the induction cooker body 1 acts on the heating sheet 221 to achieve the heating function.

[0023] In another embodiment, if Figure 4 As shown, the bottom of the cylinder 224 is integrally formed with a bottom end surface 223, and the heating sheet 221 is fixed below the bottom end surface 223 of the tea strainer 22. In this embodiment, the tea strainer 22 is made of the same material as the existing conventional tea strainer, and the heating sheet 221 can be welded and fixed on its bottom end surface, so that the electromagnetic action of the induction cooker body 1 on the heating sheet 221 is convenient, so that the heating sheet 221 generates heat.

[0024] like Figure 2 and Figure 4 As shown, the outer diameter of the heating plate 221 is larger than the outer diameter of the bottom end surface of the tea strainer 22. In actual use, the outer diameter of the heating plate 221 can be appropriately increased, thereby increasing the electromagnetic action range when the induction cooker body 1 is working, which is conducive to improving the heating efficiency.

[0025] The kettle body 2 further includes a kettle cover 23 , which is disposed above the kettle body 21 .

[0026] Therefore, the anti-dry-burning electromagnetic heating kettle of the present invention can detect the liquid level in the kettle body 21 by providing a liquid level sensor to prevent dry-burning; by providing a heating plate 221 at the bottom of the tea strainer 22, there is no need to add an electromagnetic heating base to the bottom of the entire kettle body 21, and the heating plate 221 can be heated directly by the induction cooker body 1, which greatly simplifies the processing process and reduces the overall cost.

[0027] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
