[0002] In water-based products, a water level detection device is generally installed to prevent dry burning. However, current water level detection devices cannot detect both water level and water temperature simultaneously. Furthermore, the water level detection device senses the water level through a detection unit, which is in direct contact with the outside of the product and is prone to leakage. Therefore, a grounding wire is required, which complicates the structure. Utility Model Content

[0004] The technical solution of this utility model is as follows: it includes a shell, a heat-conducting element, and a detection structure. A portion of the heat-conducting element is located outside the shell, and another portion of the heat-conducting element is installed inside the shell. The heat-conducting element is a non-metallic insulator. The detection structure includes a water level detection element and a water temperature detection element. Both the water level detection element and the water temperature detection element are located on the side of the heat-conducting element away from the outside of the shell. The water temperature detection element is close to or in contact with the heat-conducting element.

[0005] Furthermore, the detection structure also includes a PCB board, which is located on the side of the heat-conducting component away from the outside of the housing. The side of the PCB board closest to the heat-conducting component is provided with the water level detection element and the water temperature detection element.

[0006] Furthermore, the detection structure also includes a fixing member, the heat-conducting member has a mounting groove, the side of the heat-conducting member away from the outside of the housing has a first connecting hole, the first connecting hole communicates with the mounting groove, the fixing member is detachably installed in the mounting groove through the first connecting hole, the PCB board is located inside the heat-conducting member, and the PCB board is located between the fixing member and the heat-conducting member.

[0007] Furthermore, the fastener and the inner wall of the mounting groove are rotatably engaged.

[0008] Furthermore, the housing has a mounting cavity, and one side of the housing has a second communication hole communicating with the mounting cavity. At least a portion of the heat-conducting element is located inside the mounting cavity, and at least a portion of the heat-conducting element extends out of the housing through the second communication hole.

[0009] Furthermore, the heat-conducting component is movably installed in the mounting cavity. The inner wall of the mounting cavity has a blocking portion to prevent the heat-conducting component from fully extending out of the housing. The outer wall of the heat-conducting component has a protrusion located below the blocking portion. An elastic element is provided between the bottom surface of the fixing component and the bottom surface of the mounting cavity.

[0010] Furthermore, both the bottom surface of the fixing member and the bottom surface of the mounting cavity have protrusions to prevent the elastic member from moving horizontally, and the elastic member is sleeved on the protrusions.

[0011] Furthermore, the inner wall of the mounting cavity has a guide portion for guiding the heat-conducting component to move up and down, and the side wall of the heat-conducting component has a sliding groove that cooperates with the guide portion, with the guide portion located within the sliding groove.

[0014] The water level and temperature detection device according to this utility model has at least the following technical effects:

[0015] 1. This utility model places both the water level detection element and the water temperature detection element on one side of the other part of the heat-conducting component. Thus, the water level detection element can detect the water level of the liquid inside the product through the heat-conducting component, and the water temperature detection element can detect the temperature of the liquid through the heat-conducting component, achieving simultaneous detection of water level and water temperature. Since the heat-conducting component is a non-metallic insulator, there will be no leakage even though the heat-conducting component is in contact with the outside of the product, thereby avoiding the need for a grounding wire in the water level and water temperature detection device, thus avoiding complex internal structure and reducing manufacturing costs.

[0016] 2. An elastic element is provided between the bottom surface of the fixing component and the bottom surface of the mounting cavity.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figure 1 , 2 As shown in Figure 3, the water level and temperature detection device provided in the embodiment of this utility model includes a housing 100, a heat-conducting element 200, and a detection structure 300. A part of the heat-conducting element 200 is located outside the housing 100, and another part of the heat-conducting element 200 is installed inside the housing 100. The heat-conducting element 200 is a non-metallic insulator. The detection structure 300 includes a water level detection element 310 and a water temperature detection element 320. Both the water level detection element 310 and the water temperature detection element 320 are located on the side of the heat-conducting element 200 away from the outside of the housing 100 (located on the lower side of the heat-conducting element 200). The water temperature detection element 320 is close to or in contact with the heat-conducting element 200 (the lower side of the heat-conducting element 200).

[0034] This invention places both the water level detection element 310 and the water temperature detection element 320 on one side of the other part of the heat-conducting component 200 (located on the lower side of the heat-conducting component 200). Thus, the water level detection element 310 can detect the water level of the liquid inside the product through the heat-conducting component 200, and the water temperature detection element 320 can detect the temperature of the liquid through the heat-conducting component 200, achieving simultaneous detection of water level and water temperature. Since the heat-conducting component 200 is a non-metallic insulator, there will be no leakage even when the heat-conducting component 200 is in contact with the outside of the product, thereby avoiding the need for a grounding wire for the water level and water temperature detection device, thus avoiding complex structure inside the housing 100 and reducing manufacturing costs.

[0035] During operation, the container contains liquid, and the shell 100 is installed on the outside of the container. The portion of the heat-conducting element 200 located outside the shell 100 abuts against the outer wall of the container. Since the water temperature detection element 320 is close to or in contact with another part of the heat-conducting element 200, the heat of the liquid can be transferred to the water temperature detection element 320 through the heat-conducting element 200, so that the water temperature detection element 320 can detect the water level. At the same time, the water level detection element 310 passes through the heat-conducting element 200 to detect the water level of the liquid inside the container.

[0036] Specifically, the water level detection element 310 can be a capacitive water level sensor. The capacitive water level sensor can detect the water level of the liquid inside the container through insulating materials such as plastic and glass, and the housing 100 can be installed on the outside of the container. When the capacitive water level sensor is working, it uses the capacitance formed between the liquid itself and the electrodes of the capacitive water level sensor to determine the water level.

[0037] It is understandable that, provided that the water level detection element 310 can detect the liquid level in the container, other sensors can also be used for the water level detection element 310.

[0038] Furthermore, such as Figure 2 , 3 As shown, the detection structure 300 also includes a PCB board 330, which is located on the side of the heat-conducting component 200 away from the outside of the housing 100. The side of the PCB board 330 closest to the heat-conducting component 200 is provided with a water level detection element 310 and a water temperature detection element 320.

[0039] The water level detection element 310 and the water temperature detection element 320 are integrated together by PCB board 330, which facilitates assembly.

[0040] Furthermore, such as Figure 2 , 3 As shown, the detection structure 300 also includes a fixing member 340, the heat-conducting member 200 has a mounting groove 210, the side of the heat-conducting member 200 away from the outside of the housing 100 has a first connecting hole 220, the first connecting hole 220 communicates with the mounting groove 210, the fixing member 340 is detachably installed in the mounting groove 210 through the first connecting hole 220, the PCB board 330 is located in the heat-conducting member 200, and the PCB board 330 is located between the fixing member 340 and the heat-conducting member 200.

[0041] The heat-conducting component 200 has a mounting groove 210, and the fixing component 340 is detachably installed in the mounting groove 210 through the first connecting hole 220, thereby fixing the PCB board 330 in the heat-conducting component 200, so that the water level detection element 310 and the water temperature detection element 320 both abut against the heat-conducting component 200, thereby enabling the water level detection element 310 to detect the water level more accurately and the water temperature detection element 320 to detect the water temperature more accurately; and the fixing component 340, the PCB board 330 and the heat-conducting component 200 are assembled into a single component, which is convenient for assembly and disassembly.

[0042] During installation, the PCB board 330 is placed in the mounting slot 210 and then fixed in the mounting slot 210 by the fastener 340; during disassembly, only the fastener 340 needs to be removed and the PCB board 330 can be taken out from the mounting slot 210.

[0043] Specifically, the fastener 340 and the inner wall of the mounting groove 210 are connected by threads.

[0044] Furthermore, the fastener 340 and the inner wall of the mounting groove 210 are rotated and snapped together to facilitate the installation and removal of the fastener 340.

[0045] Specifically, such as Figure 4 As shown, the inner wall of the mounting groove 210 is evenly distributed with multiple snap-fit ​​portions 212, and there is a distance between the upper end of the snap-fit ​​portion 212 and the upper wall of the mounting groove 210, such as... Figure 5 As shown, the fastener 340 has multiple slots 342 corresponding to the positions of multiple snap-fit ​​parts 212. During installation, the PCB board 330 is placed in the mounting slot 210. The positions of the multiple slots 342 on the fastener 340 correspond one-to-one with the positions of the multiple snap-fit ​​parts 212. Thus, the fastener 340 can be placed in the mounting slot 210 and can be moved above the snap-fit ​​parts 212. Then, the fastener 340 is rotated so that the positions of the multiple snap-fit ​​parts 212 are staggered from the positions of the multiple slots 342. Figure 3 As shown, the snap-fit ​​part 212 blocks the fixing member 340 from moving out of the mounting slot 210, thereby fixing the PCB board 330 between the fixing member 340 and the heat-conducting member 200. When it is necessary to remove the PCB board 330, the fixing member 340 is rotated so that the positions of the multiple snap-fit ​​parts 212 correspond one-to-one with the positions of the multiple snap-fit ​​slots 342, so that the fixing member 340 and the PCB board 330 can be removed from the mounting slot 210 in sequence.

[0046] Furthermore, such as Figure 3 As shown, the housing 100 has a mounting cavity 110, and one side of the housing 100 has a second communication hole 120 communicating with the mounting cavity 110. At least a portion of the heat-conducting element 200 is located inside the mounting cavity 110, and at least a portion of the heat-conducting element 200 extends out of the housing 100 through the second communication hole 120.

[0047] The installation cavity 110 facilitates the placement of the heat-conducting component 200.

[0048] Furthermore, such as Figure 2 , 9 As shown, the heat-conducting component 200 is movably installed in the mounting cavity 110. The inner wall of the mounting cavity 110 has a blocking portion 111 for preventing the heat-conducting component 200 from fully extending out of the housing 100. The outer wall of the heat-conducting component 200 has a protrusion 201 located below the blocking portion 111. An elastic member 400 is provided between the bottom surface of the fixing member 340 and the bottom surface of the mounting cavity 110.

[0049] By incorporating an elastic element 400, which provides an outward thrust to the heat-conducting element 200, the heat-conducting element 200 is tightly attached to the outer wall of the container, thereby improving the accuracy of the detection.

[0050] It is understandable that the protrusion 201 of the heat-conducting element 200 is in close contact with the lower end of the blocking part 111 under the action of the elastic element 400, while a part of the heat-conducting element 200 extends out of the housing 100 through the second connecting hole 120, and another part of the heat-conducting element 200 is located inside the housing 100.

[0051] Furthermore, such as Figure 3 As shown, the bottom surface of the fastener 340 and the bottom surface of the mounting cavity 110 both have protrusions 341 to prevent the elastic element 400 from moving horizontally, and the elastic element 400 is sleeved on the protrusions 341.

[0052] By providing a protruding post 341, horizontal movement of the elastic element 400 is prevented when it is compressed.

[0053] Specifically, the elastic element 400 is a spring.

[0054] Furthermore, such as Figure 6 , 7 As shown in Figure 8, the inner wall of the mounting cavity 110 has a guide portion 130 for guiding the heat-conducting component 200 to move up and down, and the side wall of the heat-conducting component 200 has a groove 230 that cooperates with the guide portion 130. The guide portion 130 is located in the groove 230.

[0055] By providing a guide section 130 and a slide groove 230, the heat-conducting component 200 can only move up and down, but cannot rotate.

[0056] Furthermore, such as Figure 2 As shown, the mounting groove 210 has a groove 211 on the side away from the first connecting hole 220, and the water temperature detection element 320 is disposed in the groove 211.

[0057] This allows the water temperature sensing element 320 to be closer to the outer wall of the container, improving the detection accuracy of the water temperature sensing element 320.

[0058] Furthermore, such as Figure 2 As shown, the water level detection element 310 is a capacitive water level sensor. The detection component 311 of the capacitive water level sensor is located on the side of the PCB board 330 near the heat conductor 200. The detection component 311 abuts against the heat conductor 200 to improve the detection accuracy of the water level detection element 310.
