Claim 4 Young in view of Culbertson discloses the food temperature probe according to claim 2, wherein the transfer piece is disposed at an end of the handle body away from the probe body, and the first pole is disposed at an end of the transfer piece away from the handle body; the transfer piece is brazed to the handle body; the first pole is connected to the transfer piece by one or more of laser welding, fusion welding, cold welding, threading with glue, and threading with a sealing ring; the first pole is electrically connected to the circuit board through a first pole extension wire (Young, Figs. 3 and 7). Claim 5 Young in view of Culbertson discloses the food temperature probe according to claim 2. Young discloses attaching handle body and probe body by coupling, securing, or attachment (paragraph [0129]) but does not appear to explicitly disclose wherein the first pole and the transfer piece are connected into a whole by one or more of laser welding, fusion welding, cold welding, threading with glue, and threading with a sealing ring, and disposed at the middle of the handle body; the first pole is electrically connected to the circuit board through a first pole extension wire. Culbertson discloses joining components of a temperature probe using welding (col. 7, lns 24-36). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have incorporated attaching by welding, as disclosed by Culbertson, into the device of Young, such that the first pole and the transfer piece are connected into a whole by one or more of laser welding, fusion welding, cold welding, threading with glue, and threading with a sealing ring, and disposed at the middle of the handle body; the first pole is electrically connected to the circuit board through a first pole extension wire, for the purpose of joining with minimal non-uniformities (Culbertson, col. 7, lns 41-52). Claim 6 Young in view of Culbertson discloses the food temperature probe according to claim 2, further comprising a first insulating ceramic (Young, paragraph [0129]); the probe body is sequentially connected to the transfer piece, the first insulating ceramic (Young, paragraphs [0129-0130]). Young discloses attaching handle body and probe body by coupling, securing, or attachment (paragraph [0129]) but does not appear to explicitly disclose the first pole at an end of the probe body away from the handle body; the transfer piece is connected to the probe body through one or more of laser welding, fusion welding, cold welding, threading with glue, and threading with a sealing ring; the transfer piece is brazed to the first insulating ceramic, and the first insulating ceramic is brazed to the first pole; the first pole is electrically connected to the circuit board through a first pole extension wire. Culbertson discloses joining components of a temperature probe using welding (col. 7, lns 24-36). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have incorporated attaching by welding, as disclosed by Culbertson, into the device of Young, such that and the first pole at an end of the probe body away from the handle body; the transfer piece is connected to the probe body through one or more of laser welding, fusion welding, cold welding, threading with glue, and threading with a sealing ring; the transfer piece is brazed to the first insulating ceramic, and the first insulating ceramic is brazed to the first pole; the first pole is electrically connected to the circuit board through a first pole extension wire, for the purpose of joining with minimal non-uniformities (Culbertson, col. 7, lns 41-52).
