Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically relating to a temperature sensor that combines temperature detection and water level detection. Background Technology

[0002] In household appliances such as water purifiers, corresponding water level detection and temperature detection structures are required. In existing technologies, these structures are set up separately, which not only greatly increases the space occupied and the manufacturing cost, but also makes it impossible to pass 3C certification, thus hindering effective application and affecting its applicability to some extent, making it difficult to meet market demands. Summary of the Invention

[0003] The purpose of this invention is to provide a temperature sensor that combines temperature detection and water level detection, with a reasonable structural design that helps reduce processing costs.

[0004] The technical solution to achieve the purpose of this utility model is a temperature sensor that combines temperature detection and water level detection, including a temperature sensor, a central electrode, a cylindrical first insulator, a cylindrical electrode, and a cylindrical second insulating sleeve; The central electrode is located at the center of the cylindrical first insulator, the cylindrical electrode is sleeved on the outside of the cylindrical first insulator, and the cylindrical second insulating sleeve is sleeved on the outside of the cylindrical electrode; The central electrode, the cylindrical first insulator, the cylindrical electrode, and the cylindrical second insulating sleeve are arranged in a stepped shape with a high center and low edges. Both the central electrode and the cylindrical electrode are fixed with connection pins; The temperature sensor is located at the center of the cylindrical first insulator, and a pin-type connector is fixed on the connection terminal of the temperature sensor.

[0005] A further preferred embodiment is that the bottom end of the cylindrical electrode is fixed with a connecting external thread; The external thread of the connection extends out from the lower part of the cylindrical second insulating sleeve.

[0006] A further preferred embodiment is that the outer diameter of the central electrode is the same as the inner diameter of the cylindrical first insulator, and the inner diameter of the cylindrical electrode is the same as the outer diameter of the cylindrical first insulator. The inner diameter of the cylindrical second insulating sleeve is the same as the outer diameter of the middle part of the cylindrical electrode.

[0007] A further preferred embodiment is that the cylindrical first insulator is a transparent insulating plastic component; The second insulating sleeve is an insulating plastic part.

[0008] A further preferred embodiment is that the length and width of the temperature sensor are both smaller than the inner diameter of the cylindrical first insulator; One edge of the temperature sensor is glued or snapped to the inner wall of the cylindrical first insulator.

[0009] This invention has several advantages: its structure is rationally designed, enabling water level detection through a central electrode and a cylindrical electrode. Simultaneously, the temperature sensor is directly housed within the cylindrical first insulator, integrating the temperature sensor and water level detection into one unit. This not only reduces processing and assembly costs but also ensures the effectiveness and reliability of both water level and temperature detection. Furthermore, the stepped arrangement of the central electrode, the cylindrical first insulator, the cylindrical electrode, and the cylindrical second insulating sleeve (higher at the center and lower at the edges) guarantees detection accuracy, reduces false detections, lowers processing costs, and significantly expands its applicability.

[0012] 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. Example

[0013] See Figures 1 to 3As shown, a temperature sensor combining temperature sensing and water level detection includes a temperature sensor 1, a central electrode 2, a cylindrical first insulator 3, a cylindrical electrode 4, and a cylindrical second insulating sleeve 5. In this embodiment, the temperature sensor uses a conventional structure from the prior art, simply applied. During assembly, the central electrode is located at the center of the cylindrical first insulator, the cylindrical electrode is sleeved on the outside of the cylindrical first insulator, and the cylindrical second insulating sleeve is sleeved on the outside of the cylindrical electrode. The central electrode, cylindrical first insulator, cylindrical electrode, and cylindrical second insulating sleeve are arranged in a stepped shape with a higher center and lower edges. Both the central electrode and the cylindrical electrode are fixed with connection pins 6. The temperature sensor is located at the center of the cylindrical first insulator, and a pin-type connector 7 is fixed to the connection terminal of the temperature sensor. The pin-type connector is a conventional structure from the prior art, facilitating connection with external circuits, and corresponding connectors can also be connected to its connection pins for easy connection with external circuits.

[0014] In practical applications, the bottom end of the cylindrical electrode is fixed with an external thread 8; the external thread extends out from the lower part of the cylindrical second insulating sleeve. This external thread facilitates installation inside the corresponding electrical appliance, ensuring convenient and effective installation.

[0015] In this embodiment, the outer diameter of the central electrode is the same as the inner diameter of the cylindrical first insulator, and the inner diameter of the cylindrical electrode is the same as the outer diameter of the cylindrical first insulator; the inner diameter of the cylindrical second insulating sleeve is the same as the outer diameter of the middle part of the cylindrical electrode. The cylindrical first insulator is a transparent insulating plastic part; the second insulating sleeve is an insulating plastic part.

[0016] The length and width of the temperature sensor are both smaller than the inner diameter of the cylindrical first insulator; one edge of the temperature sensor is glued or snapped to the inner wall of the cylindrical first insulator. This structure ensures convenient and effective installation of the temperature sensor, and the overall structure also facilitates 3C certification, expanding its applicability.

[0017] This invention has several advantages: its structure is rationally designed, enabling water level detection through a central electrode and a cylindrical electrode. Simultaneously, the temperature sensor is directly housed within the cylindrical first insulator, integrating the temperature sensor and water level detection into one unit. This not only reduces processing and assembly costs but also ensures the effectiveness and reliability of both water level and temperature detection. Furthermore, the stepped arrangement of the central electrode, the cylindrical first insulator, the cylindrical electrode, and the cylindrical second insulating sleeve (higher at the center and lower at the edges) guarantees detection accuracy, reduces false detections, lowers processing costs, and significantly expands its applicability.

[0018] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
