Microwave oven and magnetron detection device

The invention discloses a microwave oven and magnetron detection device. The device comprises: a current conversion module which is used for converting an alternating current flowing through a magnetron into an alternating voltage; a rectification module which is connected with the current conversion module, wherein the rectification module is used for rectifying the alternating-current voltage to obtain direct-current voltage; a sampling module which is connected with the rectification module, wherein the sampling module is used for generating sampling voltage according to the direct current voltage; and a detection module which is connected with the sampling module, wherein the detection module is used for determining the working state of the magnetron according to the sampling voltage. Therefore, the working state of the magnetron is determined according to the sampling voltage, so that the working state of the magnetron can be monitored in real time, the abnormal working condition of the magnetron can be
