An integrated antenna handle and a wireless food temperature probe are provided. The integrated antenna handle of the present disclosure includes a handle body, a metal antenna is provided on an outer wall of the handle body, and a protective layer is provided on an outer wall of the handle body and covers the metal antenna. The integrated antenna handle is the first in the field of temperature measurement handles to achieve an external placement of the metal antenna on the outside of the handle, thus breaking through physical limitations of the handle on the metal antenna. The metal antenna is physically isolated from the power lines and sensor wires inside the outer wall of the handle body. The handle body can also be made of non-metallic materials, thereby greatly reducing the signal interference or shielding of the metal antenna.

Integrated antenna handle and wireless food temperature probe

A sensor multifunctional Bluetooth food probe is provided; a first sensor is provided at a front end of a probe body tube and configured to measure food temperature; the first sensor is connected to a PCB board and a main control circuit through first and second wires, the probe body tube is provided with a first charging electrode; a second sensor is provided at one end of a handle and configured to measure an environmental temperature; the second sensor is connected to the PCB board and main control circuit through third and fourth wires; the handle serves as an antenna or a second charging electrode; a switching circuit is configured to switch the third and fourth wires to a charging module or a temperature measurement module. In this application, the antenna is externally mounted and has fewer internal wires to reduce interference signals.

Sensor multifunctional Bluetooth food probe

A temperature measurement circuit structure and a temperature probe are provided. The temperature measurement circuit structure includes a first temperature measurement circuit, a second temperature measurement circuit, a charging module, and a switching circuit, the switching circuit is connected to the charging module; a third wire and a fourth wire of the second temperature measurement circuit are connected to a control chip through a PCBA board; a first charging wire of the charging module is connected to the control chip through the PCBA board; in a charging state, the switching circuit connects the third or fourth wire to the charging module and serves as a second charging wire of the charging module; in a non-charging state, the switching circuit disconnects the third or fourth wire, which serves as the second charging wire, from the charging module. By switching the circuit, one wire inside a handle was reduced.
