Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to an integrated sensor. Background Technology

[0002] In daily life and industrial production, monitoring the internal temperature and water level of liquid containers such as kettles and water tanks is crucial. The traditional approach is to install temperature sensors and water level sensors separately to achieve these two functions. However, this approach not only increases the complexity and cost of the equipment, but also has problems such as inconvenient installation and difficult maintenance. Especially in water level detection, many integrated sensors still use a long-term power supply method, which not only increases energy consumption, but may also cause the liquid to be electrolyzed, affecting water quality and safety.

[0003] In summary, this provides a more efficient and secure solution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an integrated sensor that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated sensor, including a combined sensor and a kettle body, wherein the combined sensor is composed of a temperature sensor and a water level sensor integrated into one unit, a sealing mechanism is sleeved on the combined sensor, the sealing mechanism is matched and snapped into the kettle body, and the water level sensor in the combined sensor can be independently controlled and connected.

[0006] Furthermore, a convex ring is fixed to the outer end of the combined sensor, the lower end of the combined sensor is a threaded end, an installation hole is opened in the body of the pot, and a threaded connecting cylinder concentrically arranged with the installation hole is fixedly connected to the lower end of the pot body. The threaded end of the combined sensor passes through the pot body and is threadedly connected to the threaded connecting cylinder. The sealing mechanism is located at the lower end of the convex ring.

[0007] Furthermore, the sealing mechanism includes a sealing ring, and a sealing sheet is fixed to the upper end of the sealing ring. The size of the sealing sheet is set to be the same as the size of the convex ring to ensure the sealing effect.

[0008] Furthermore, the kettle body is made of metal, and an electrical electrode is fixedly connected to the lower end of the kettle body. The electrical electrode is electrically connected to one end of the water level sensor in the combined sensor.

[0009] Furthermore, the combined sensor is located at an off-center position at the bottom of the kettle body.

[0010] Furthermore, the thickness of the sealing sheet is set to 5mm.

[0011] Furthermore, the combined sensor also includes a control circuit, which includes an MCU control chip, and the MCU control chip is equipped with GPIO1 signal and GPIO2 signal.

[0012] Compared to the aforementioned background technology, the integrated sensor provided in this application includes temperature sensor and water level sensor, which are currently very mature technologies, as well as core components such as combined sensor and electrode. Its principle relies on integrating the temperature sensor and water level sensor into one unit and controlling the water level sensor independently to avoid electrolytic effects on water quality caused by prolonged power supply.

[0013] This invention provides an integrated sensor. Compared with the prior art, it has the following advantages: This new sensor, by integrating a temperature sensor and a water level sensor into one unit, not only simplifies the equipment structure and reduces costs, but also improves the accuracy and reliability of monitoring. Its unique sealing structure and installation method ensure stable operation of the sensor within the container, avoiding malfunctions caused by improper installation or poor sealing, a common problem with traditional sensors. By controlling the power-on time of the water level detection function, energy consumption is effectively reduced, the risk of liquid electrolysis is avoided, the equipment's lifespan is extended, and operational safety is improved.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an integrated sensor; specifically, it consists of a combined sensor 3, which integrates a temperature sensor and a water level sensor. A convex ring 4 is fixed to the outer end of the combined sensor 3, and the lower end of the combined sensor 3 is a threaded end. A sealing ring 6 is fitted on the outer side of the threaded end, and a sealing sheet 5 is fixed to the upper end of the sealing ring 6. The size of the sealing sheet 5 is the same as the size of the convex ring 4. The combined sensor 3 is installed inside the kettle body 1, and an installation hole 2 is provided inside the kettle body 1. A threaded connecting cylinder 7 is fixed to the bottom end of the kettle body 1. The combined sensor 3, carrying the sealing ring 6 and the sealing sheet 5, is installed in the installation hole 2 of the kettle body 1. The sealing ring 6 is located inside the installation hole 2, and the sealing sheet 5 is located inside the kettle body 1. The threaded end of the combined sensor 3 is threadedly connected to the threaded connecting cylinder 7. A stable seal is formed by rotating and pressing the sealing ring 6 through the threaded connection. The kettle body 1 is made of metal, and an electrode 8 is fixed at the lower end of the kettle body 1. When water is poured into the kettle body 1, the water submerges the sealing plate 5 and contacts the combined sensor 3. At this time, the temperature sensor in the combined sensor 3 is activated. When it is necessary to detect the water level during boiling, the electrode 8 is energized by an external control switch. At this time, the water inside contacts the combined sensor 3, and the energization of the electrode 8 allows the water level to be detected along the inside of the kettle body 1, thereby achieving the functions of detecting water level and temperature. Moreover, the water level detection end is energized only when it is needed and does not need to be energized when it is not needed. Therefore, compared with traditional temperature sensors and water level sensors, this design can reduce the long-term energization of the internal water, thereby preventing the water inside the kettle body 1 from being electrolyzed. The combined sensor 3 is located at an off-center position at the bottom of the kettle body 1. This off-center position provides considerations for measurement accuracy, spatial layout, safety, and maintenance. This design ensures that the combined sensor 3 can accurately sense changes in water temperature and transmit them to the control unit to control the working state of the heating element, thereby meeting the user's needs. The sealing sheet 5 is set to be 5mm thick, so that at least 5mm of water is injected into the kettle body 1. When the water level is below 5mm, the combined sensor 3 will not be triggered, thus providing short-term heating to the kettle body 1 and preventing the kettle body 1 from being dry-burned, which would affect its service life.

[0019] Please read Figure 5-6 As shown, the working principle of water detection 1) Use capacitors C1 and C2 to isolate the DC power supply to prevent the effect of water electrolysis.

[0020] 2) During operation, GPIO1 outputs a 5.0V PWM signal. If there is water, the PWM signal will be coupled to GPIO2 through the water. The MCU can then detect this signal.

[0021] 3) When GPIO1 outputs a PWM signal, if the kettle has no water, no voltage will be detected at GPIO2. When there is water, GPIO2 will detect a PWM level signal greater than or equal to 1.0V. A voltage less than 1.0V indicates no water. (The level of this voltage is related to the adjustable resistance values ​​of resistors R1, R2, and R4, which is well-known to those skilled in the art.) The power supply section uses a front-to-back isolation design to ensure that the power output will not cause electric shock safety issues.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
