Abstract

The invention discloses a noninvasive waterproof key structure of a pan. The noninvasive waterproof key structure comprises a circuit board switch sealed in a shell, keys arranged outside the shell and matched with the circuit board switch, a key stroke cavity is manufactured outside the shell, the keys are arranged in the key stroke cavity in a sliding mode, and the inner ends of the keys can get close to or away from the circuit board switch; a strong magnetic piece is fixed to the inner end of each key, and the circuit board switch is a Hall magneto-dependent sensor which can be coupled with the strong magnetic pieces. The defect that small holes need to be formed in the shell for installing existing waterproof keys is overcome, and the potential safety hazard that in the prior art, due to long-term use, a PVC waterproof film is aged, and the small holes directly leak water is avoided. The noninvasive waterproof key structure has the advantages of being simple in structure, sensitive in control and high in waterproofness, and a touch switch with open pores is not needed.

Description

technical field [0001] The invention relates to a waterproof key structure for kitchen utensils, in particular to a non-invasive waterproof key structure for pot utensils. Background technique [0002] With the rapid development of economy and science and technology, and the continuous improvement of people's living standards, there are more and more various intelligent kitchen utensils in life. These intelligent kitchen utensils often have computer control circuit boards and corresponding program setting buttons. Since kitchen utensils will inevitably come into contact with water, the waterproof structure of kitchen utensil buttons is particularly important, which is directly related to the safety and service life of kitchen utensils. [0003] The invention patent with the patent number of 201420085508.1 discloses a waterproof structure for the control panel of a miniature rice cooker, which includes a pot shell and a control circuit. The surface of the control panel is s...
