[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] This embodiment provides an integrated water level detection and temperature sensing device, including a detection component, a temperature sensor 300, and a housing 100;

[0026] One end of the outer casing 100 has a through hole;

[0027] The detection component includes a detection chip 201 and a control chip. The control chip is disposed inside the housing 100. The detection chip 201 is disposed inside the housing 100 and electrically connected to the control chip. One side of the detection chip 201 is the detection end, and the other side of the detection chip 201 extends outward from the housing 100 through a through hole. The detection chip 201 is used to detect water level and transmit temperature.

[0028] Temperature sensor 300 is disposed inside housing 100, and the detection end of temperature sensor 300 is disposed on detection plate 201.

[0029] The detection plate 201 extends out of the outer shell 100 through a through hole and is used to detect water level and water temperature. One side of the detection plate 201 is the detection end, and the temperature sensor 300 is set on the detection plate 201 and abuts against the other side of the detection plate 201. When one side of the detection plate 201 abuts against the container to be tested, the water temperature is transferred to the temperature sensor 300 by heat transfer, thereby realizing water temperature detection.

[0030] Meanwhile, the device can detect the liquid level inside the container by means of one or more of, including but not limited to, capacitive water level sensors, ultrasonic water level sensors, and photoelectric water level sensors.

[0031] In this embodiment, an integrated water level detection and temperature sensing device is provided, which integrates water level detection and water temperature detection into one unit. The detection end for water level detection and the detection end for water temperature detection are both located at the same location on the detection plate 201, making the detection device compact and fully functional. At the same time, the device can detect the liquid level and temperature inside the container from outside the container, allowing a single device to detect multiple containers to be tested, which can effectively improve the applicability of the device.

[0032] In a further embodiment of this utility model, a capacitive water level sensor is included, which is electrically connected to a control chip, and the detection chip 201 is the detection end of the capacitive water level sensor.

[0033] In this embodiment, a capacitive water level sensor is used as the detection component. The capacitive water level sensor senses the water level by detecting the change in capacitance between its detection end, i.e., the detection piece 201, and the surrounding medium. The capacitive water level sensor utilizes the dielectric properties of the liquid to detect the water level. The sensor contains a capacitor; when liquid comes into contact with the capacitor, the capacitance value changes. By measuring the change in capacitance value, the water level can be determined.

[0034] Capacitive water level sensors can effectively detect liquids stored in non-metallic containers, and have no special requirements for the liquid medium. They also feature high stability, high sensitivity, and strong anti-interference capabilities.

[0035] In a further embodiment of this utility model, an elastic component is included. The elastic component includes a first fixing plate 401, a second fixing plate 403, and a spring 402. One side of the first fixing plate 401 abuts against the inner surface of the other side of the outer shell 100. The other side of the first fixing plate 401 is connected to one end of the spring 402. The other end of the spring 402 is connected to one side of the second fixing plate 403. The other side of the second fixing plate 403 abuts against the detection component.

[0036] The first fixing plate 401 and the second fixing plate 403 are used to fix the spring 402, and at the same time can increase the contact area between the elastic component and the detection component, so as to avoid damage to the components in the detection component due to excessive pressure.

[0037] In this embodiment, an elastic component is introduced to enhance the stability and reliability of the detection component. The elastic component consists of a first fixing plate 401, a second fixing plate 403, and a spring 402. When the device detects water level and water temperature, the elastic component can provide an outward thrust to the detection component, pressing the detection piece 201 tightly against the outer wall of the container to be detected, thereby improving the accuracy of the detection.

[0038] In a further embodiment of this utility model, the control chip is a PCB board 202, the PCB board 202 has a first connection hole 203, the other side of the detection piece 201 is provided with a connecting block 204, the connecting block 204 on the detection piece 201 passes through the first connection hole 203 and is riveted to the PCB board 202, and one side of the PCB board 202 abuts against the other side of the second fixing plate 403.

[0039] In this embodiment, the control chip uses a PCB board 202, which is a common carrier for electronic components. The PCB board 202 also has a first connection hole 203 for riveting to the connection block 204 on the detection chip 201, thereby achieving an electrical connection. This connection method is simple, reliable, and easy to manufacture and maintain.

[0040] In a further embodiment of this utility model, a limiting block 404 is included. One side of the limiting block 404 abuts against the other side of the PCB board 202. A second connecting hole 406 is provided on the limiting block 404. The connecting block 204 on the detection piece 201 passes through the first connecting hole 203 and the second connecting hole 406 and is riveted to the PCB board 202. The limiting block 404 is located inside the outer shell 100 and cannot pass through the through hole.

[0041] In this embodiment, a limiting block 404 is introduced to limit the movement range of the PCB board 202 and the detection piece 201. One side of the limiting block 404 abuts against the other side of the PCB board 202, and the second connecting hole 406 on it cooperates with the connecting block 204 on the detection piece 201 to jointly fix the detection component.

[0042] In a further embodiment of the present invention, a protrusion 101 is provided on the inner side wall of the outer shell 100 near the through hole, and a groove 405 is provided on the outer side wall of the limiting block 404. The groove 405 cooperates with the protrusion 101 to make the limiting block 404 reciprocate with the inner side wall of the outer shell 100 towards the through hole and away from the through hole.

[0043] In this embodiment, the groove 405 on the outer sidewall of the limiting block 404 cooperates with the protrusion 101 on the inner sidewall of the outer shell 100, so that the limiting block 404 can reciprocate within a certain range to adapt to the needs of water level changes and temperature detection.

[0044] In a further embodiment of this utility model, the detection end of the temperature sensor 300 is attached to the other side of the detection piece 201, and the signal end of the temperature sensor 300 extends outward from the outer casing 100 to be electrically connected to external devices and output the temperature detection result.

[0045] In this embodiment, the detection end of the temperature sensor 300 abuts against the other side of the detection piece 201 to directly acquire the temperature information sensed by the detection piece 201. The signal end of the temperature sensor 300 extends outward from the housing 100 to make electrical connections with external devices and output temperature detection results. This design enables the temperature sensor 300 to accurately reflect the temperature conditions of the environment in contact with the detection piece 201.

[0046] In a further embodiment of this utility model, the outer shell 100 has a communication hole 102 for controlling the chip to make electrical connections with external devices and output water level detection results.

[0047] In this embodiment, the outer casing 100 also has a communication port 102 for electrically connecting the control chip to external devices and outputting water level detection results. Users can then obtain water level and temperature information in real time through external devices, enabling comprehensive environmental monitoring.

[0048] In a further embodiment of this utility model, the temperature sensor 300 is electrically connected to the control chip, and the temperature sensor 300 outputs the temperature detection result to the outside world through the control chip.

[0049] In this embodiment, the temperature sensor 300 and the control chip can work together to detect the liquid in the container to be tested. At the same time, the control chip can also process and analyze the temperature data to improve the accuracy and reliability of the data.

[0050] In a further embodiment of the present invention, a decorative ring 500 is included, which is disposed outside the outer shell 100 and connected to the other end of the outer shell 100.

[0051] In this embodiment, a decorative ring 500 is introduced to enhance the appearance of the device and improve its practicality.
