1. A temperature measurement device, wherein the temperature measurement device comprises a temperature probe, wherein the temperature probe comprises:
a cylinder and a handle, wherein the handle has a distal opening away from the cylinder, a proximal opening detachably connected to the cylinder and a first channel which runs through the distal opening and the proximal opening, a cross-sectional area of the handle gradually decreases from the distal opening to the proximal opening, the bottom of the proximal opening is provided with a first step that extends radially inward, and the inner diameter Rd of the distal opening is greater than the inner diameter Rp of the first step, the cylinder comprises a tip for inserting into food, a cylindrical portion, and an upper end opposite to the tip, the upper end has a second step that is connected to the cylindrical portion and extends radially outward, the diameter Rs of the second step is greater than the diameter Rc of the cylindrical portion, wherein Rd>Rs>Rp>Rc,
wherein the temperature probe further comprises an upper cover connected to the distal opening, wherein the upper cover comprises a peripheral portion, an annular portion, and a circular portion, wherein the annular portion is located between the peripheral portion and the circular portion, wherein the annular portion and the circular portion are made of electrically conductive materials, and the annular portion is made of electrical insulating materials, the circular portion and the annular portion are used as electric poles to charge the temperature probe, the electric poles including a positive pole and a negative pole, and the annular portion is used to electrically isolate the circular portion and the annular portion,
one end of the peripheral portion near the distal opening is provided with one or more accommodating cavities as a first electrode, and one end of the circular portion near the distal opening is provided with a U-shaped clamping arm as a second electrode, the accommodating cavities and the U-shaped clamping arm are formed as an accommodating channel to clamp one end of a heat-resisting substrate circuit board near the upper cover and an electrically conducting channel to electrically connected the peripheral portion and the circular portion with the heat-resisting substrate circuit board respectively.
