The shell 1 has a detection end face 11, a placement cavity 12 and a detection port 13 connected with the placement cavity. The detection end face 11 is used for direct contact with the external water body, facilitating the combination of the detection metal sheet 2 for water level and temperature sensing. The design of the placement cavity 12 provides installation space for internal elements. The detection metal sheet 2 is adaptively installed in the detection port 13. The detection metal sheet 2 serves as a medium for water level and temperature conduction. Its material is preferably a metal with good thermal conductivity and corrosion resistance to ensure the accuracy and long-term stability of detection. Preferably, the detection metal sheet 2 is a copper sheet. The thermosensitive element 3 is embedded in the placement cavity and attached to the back end face of the detection metal sheet 2. It is used for detecting the temperature of the water body, converting the temperature signal into an electrical signal and feeding back to the control circuit board 4 for subsequent processing and output. The control circuit board 4 is embedded in the placement cavity and electrically connected with the thermosensitive element 3. It is responsible for receiving the temperature signal transmitted by the thermosensitive element 3 and the water level signal transmitted by the water level detection element 5, and performing amplification, filtering, A / D conversion and other processing. Finally, the temperature data and water level data are output to external devices or systems. The water level detection element 5 is embedded in the placement cavity and electrically connected with the control circuit board 4. The water level detection element 5 has a detection metal rod 6 connected with the detection metal sheet 2. When the water body contacts the detection metal sheet 2, it is transmitted to the water level detection element 5 through the detection metal rod 6 as a medium. The water level detection element 5 generates a corresponding water level signal and feeds back to the control circuit board 4. Specifically, the thermosensitive element 3 is connected to the front end face of the control circuit board 4. The water level detection element 5 is connected to the back end face of the control circuit board 4. This design allows the thermosensitive element 3 to directly contact the detection metal sheet 2, making temperature detection more accurate. At the same time, the positions of the thermosensitive element 3 and the water level detection element 5 are optimized, and the positions and spaces on the control circuit board 4 are utilized, which is beneficial to the compact design of the structure.

[0032] The water level and temperature double combination detection module sets the detection metal sheet 2, the thermosensitive element 3, the control circuit board 4 and the water level detection element 5 in combination on the shell 1, integrates the water level detection and temperature detection functions in one module, greatly simplifies the installation process, improves the installation efficiency and reduces the cost; at the same time, the modular design of the integrated water level and temperature double combination detection makes the maintenance and replacement of elements more convenient and fast, which is beneficial to be applied in various water environments that need to monitor water level and temperature at the same time, such as hot water kettle, coffee machine, hot water machine and other household appliances. At the same time, through the close cooperation of the detection metal sheet 2 and the thermosensitive element 3, and through the detection metal rod 6 to realize the cooperation between the water level detection element 5 and the detection metal sheet 2, and then using one control circuit board 4 to accurately process the data of two functions, the number of parts such as the shell 1, the control circuit board 4 and the power cord is reduced, and the accurate monitoring of water level and temperature is realized during detection.

In addition, the sealing glue body 7 makes the whole module form a whole structure, increases the mechanical strength of the module; it can also reduce the influence of external electromagnetic interference on the internal elements, and also can reduce the interference between the internal elements during signal transmission. For example, if the control circuit board 4 is interfered by external electromagnetic interference during signal transmission and processing, signal distortion or error may occur, the sealing glue body 7 can play a certain electromagnetic shielding role, so as to ensure the stability and accuracy of signal transmission. Preferably, the sealing glue body 7 is an epoxy resin glue body.

The detection metal sheet 2 is embedded in the positioning groove 14 and is sealed and fixed by using waterproof fixing glue, and the detection metal sheet 2 is reasonably designed to be horizontal to the detection end face 11, so that water level and temperature monitoring can be better realized. Of course, the water level and temperature double combination detection module also needs to be well waterproofed to prevent water from entering the inside of the shell 1 and affecting the monitoring of the water level and the temperature.

[0036] In the embodiment, the water level and temperature double combination detection module further comprises a positive electrode line 8, a negative electrode line 9 and a grounding line 10; the positive electrode line 8, the negative electrode line 9 and the grounding line 10 are all electrically connected with the control circuit board 4. Preferably, the shell 1 has a threading hole 15 through which the positive electrode line 8, the negative electrode line 9 and the grounding line 10 pass. The positive electrode line 8 and the negative electrode line 9 are used to realize power-on of the water level and temperature double combination detection module, so as to facilitate water level and temperature monitoring.
