Description

Technical Field

[0001] The utility model relates to the technical field of electric kettles, in particular to an induction head. Background Art

[0002] The sensor head of the electric kettle can control the addition and stop of water in the electric kettle, and can also control the heat and stop heating. The current structure of the sensor head is that the sensor tube and the sensor head are integrated. The material of the sensor tube and the sensor head is the same, which makes it impossible to replace the sensor head with other materials. The induction sensitivity of sensor heads of different materials is different, so the integrated sensor head is difficult to apply to different usage scenarios. Utility Model Content

[0003] The purpose of the utility model is to provide a sensor head to solve the problems raised in the above background technology.

[0004] To achieve the above object, the utility model provides the following technical solutions: an induction head, comprising an induction tube, the upper end of the induction tube is in a cap shape, and a titanium alloy riveting sheet is riveted to the cap of the induction tube. Titanium alloy, as a light and high-strength metal material, can ensure that the induction head can maintain a stable working state even in a high-stress environment, thereby extending the service life of the induction head; titanium alloy has good corrosion resistance, which means that the induction head can better resist the erosion of adverse factors such as scale and corrosion, and maintain its long-term stable performance;

[0005] A quartz tube, wherein the quartz tube is sleeved on the surface of the sensing tube, and the lower end of the sensing tube extends out of the quartz tube. The quartz tube can separate the sensing head from water to prevent the sensing head from rusting;

[0006] A silicone plug is sleeved on the lower end of the sensing tube and is connected to the quartz tube to achieve sealing and isolation of the sensing head.

[0007] Furthermore, a sealing ring is connected to the upper surface of the sensing tube, and the sealing ring is connected to the upper end of the quartz tube. A silicone ring is fixedly connected to the surface of the silicone plug, and the silicone ring is against the lower end of the quartz tube to seal the entire gap of the sensing head, and the waterproof effect is stable. An annular groove is provided on the upper surface of the silicone ring, and a plug-in ring is fixedly connected to the lower end of the quartz tube. The plug-in ring is inserted into the annular groove to improve the stability of the connection between the quartz tube and the silicone plug.

[0008] Compared with the prior art, the utility model has the following beneficial effects: by riveting a titanium alloy riveting sheet on the upper end of the sensing tube, due to the excellent corrosion resistance of titanium metal, a riveted structure is adopted to fix it on the sensing tube, which can not only utilize the characteristics of titanium metal to protect the sensing tube, but also control the amount of titanium metal used, so that the sensing head can be manufactured by splicing different materials, saving materials and reducing costs. The quartz tube and the silicone plug isolate the sensing tube from the water in the container of the kettle, which can prevent the sensing head from corrosion and make the temperature sensing more accurate.
