[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1 to 4 As shown, a connecting probe structure of an electric heating appliance includes a connecting pipe 1, wherein the connecting pipe 1 includes a longitudinal pipe section 11 and a transverse pipe section 12, wherein the longitudinal pipe section 11 of the connecting pipe 1 forms a water receiving pipe for connecting to a heating container A, and installation ports 121 are respectively provided at both ends of the transverse pipe section 12 of the connecting pipe 1, wherein a temperature sensing probe 2 is assembled and connected in one of the installation ports 121, and a water level detection probe 3 is assembled and connected in the other installation port 121, and the sensing end faces of the temperature sensing probe 2 and the water level detection probe 3 are respectively inserted into the pipe cavity and arranged opposite to each other.

[0023] When the heating container A of this electric heating appliance is made of all-glass, sensing devices such as the temperature sensor 2 and the water level detection probe 3 can be placed outside the heating container A, so that the bottom of the heating container A can remain in a complete glass state, and the whole can remain transparent and beautiful.

[0024] The longitudinal pipe section 11 and the transverse pipe section 12 of the connecting pipe fitting 1 are connected to the side wall of the heating container A in the horizontal direction; the tube lumens of the longitudinal pipe section 11 and the transverse pipe section 12 form a communicating vessel principle with the inner cavity of the heating container A, so that the level of the transverse pipe section 12 can correctly reflect the water level in the inner cavity of the heating container A, thereby making an accurate judgment.

[0025] The inner wall of the installation port 121 is provided with an internal thread portion 122, and the outer walls of the temperature sensing probe 2 and the water level detection probe 3 are provided with an external thread portion 401. Through the cooperation between the external thread portion 401 and the internal thread portion 122, the temperature sensing probe 2 and the water level detection probe 3 are respectively screwed into the installation port 121; the temperature sensing probe 2 and the water level detection probe 3 adopt a simple fixing method, which is convenient and quick to install, with high assembly efficiency, and this fixing method can achieve a tight connection and reduce water leakage.

[0026] The temperature sensing probe 2 and the water level detection probe 3 both include a probe body 41 and a hollow bolt 42. The probe body 41 is embedded in the hollow bolt 42 and is provided with a pressure ring 43 that abuts against the front end of the hollow bolt 42. The connecting pipe 1 is provided with a step surface 123 corresponding to the pressure ring 43. After the hollow bolt 42 is screwed to the internal threaded portion 122, the pressure ring 43 is pressed between the hollow bolt 42 and the step surface 123 to fix the probe body 41. This structure eliminates the need for glue or welding to fix the probe body 41, making it convenient for the probe body 41 to be disassembled and replaced when damaged, and the matching hollow bolt 42 can be reused.

[0027] A silicone sealing ring 5 is also pressed between the pressure ring 43 and the step surface 123; the silicone sealing ring 5 can seal the gap between the temperature sensing probe 2 or the water level detection probe 3 and the installation port 121 to prevent water leakage.

[0028] It also includes an upper coupler 6, in which at least three groups of conductors 61 are arranged. The two lead wires of the temperature sensing probe 2 are electrically connected to two groups of conductors 61, and the lead wire of the water level detection probe 3 is electrically connected to one group of conductors 61; the heating container A is made detachable through the upper coupler 6.

[0029] When the connecting probe structure is installed, the side wall of the heating container A will be connected to the handle A1. The connecting probe structure and the upper coupler 6 are both arranged at the bottom of the handle A1, so that they can be hidden in the handle A1 without affecting the appearance of the heating container A.

[0030] The transverse pipe section 12 of the connecting pipe fitting 1 is also connected to a water inlet interface 13, which is arranged between the two installation ports 121; by adding the water inlet interface 13, the heating container A can automatically fill or discharge water internally or externally through the connecting pipe fitting 1, and there is live water flowing through the connecting pipe fitting 1, which can improve the detection accuracy of the temperature sensor 2 and the water level detection probe 3.

[0031] The upper coupler 6 is provided with a central assembly channel 601, and a water valve core 7 is assembled and connected in the central assembly channel 601. The water valve core 7 is connected to the water inlet interface 13 through a pipe 8; when the upper coupler 6 is coupled to the lower coupler in the base, the water path between the upper coupler and the base can be connected, so that the power supply and water supply structures are integrated, the structure is simpler and more compact, the space occupied, and the operation is completed in one step.

[0032] The water inlet interface 13 and the water receiving pipe are arranged perpendicular to each other; and the connecting pipe 1 and the water inlet interface 13 are integrally formed by injection molding; the water inlet interface 13 and the water receiving pipe are arranged in different directions so that the water in the connecting pipe 1 does not flow in a straight line. When reversing, the time the water stays in the connecting pipe 1 is increased, so that the water is fully in contact with the sensing end faces of the temperature sensing probe 2 and the water level detection probe 3.
