Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor for a constant temperature water heater. Background Art

[0002] Water heaters typically use temperature sensors to monitor and control water temperature to ensure hot water is provided within a set temperature range. Temperature sensors are usually installed near the water inlet and outlet of the water heater or near the heating pipe to promptly detect water temperature changes and feed back to the control system. By rationally configuring and using appropriate types of temperature sensors, the water temperature inside the water heater can be effectively monitored and adjusted, improving energy efficiency, extending equipment life, and providing users with a comfortable, safe and reliable bathing experience. During transportation, the detection end of existing temperature sensors is mostly exposed to the outside. If bumped, it is not only easily damaged but also affects the accuracy during use. Therefore, we have introduced a temperature sensor for constant temperature water heaters. Utility Model Content

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A temperature sensor for a constant temperature water heater includes a temperature sensor body 1, a threaded connection portion 2 is mounted on the upper portion of the temperature sensor body 1, a detection end 5 is mounted on the upper end of the threaded connection portion 2, a protective device 3 is movably connected to the outer surface of the detection end 5, a wire 6 is fixedly connected to the lower end of the temperature sensor body 1, a connector 4 is fixedly connected to the end of the wire 6 away from the temperature sensor body 1, and a disassembly device 7 is sleeved on the outer surface of the wire 6.

[0025] In this embodiment, the protective device 3 includes a sleeve 31, and the lower end of the sleeve 31 is fixedly connected to a pressure plate 33. The pressure plate 33 and the sleeve 31 are an integrally formed structure. Three reinforcing ribs 32 are fixedly connected to the outer surface of the sleeve 31. The ends of the three reinforcing ribs 32 that are away from each other are all arc-shaped structures. A cavity 35 is opened in the sleeve 31, and an internal thread 34 is provided on the lower part of the inner wall of the cavity 35; the sleeve 31 is threadedly connected to the threaded connection part 2 through the internal thread 34, and the sleeve 31 is movably connected to the detection end 5, and the upper end of the detection end 5 does not contact the sleeve 31; the temperature sensor body 1 is a hexagonal structure, and an arc groove 11 is opened on the outside of the upper end of the sleeve 31, and a sealing ring 12 is movably connected in the arc groove 11; the sealing ring 12 does not contact the threaded connection part 2, and the sealing ring 12 contacts the lower end of the pressure plate 33.

[0026] According to the above solution, after the sleeve 31 is sleeved onto the detection end 5 , the sleeve 31 cooperates with the reinforcing rib 32 to protect the detection end 5 .

[0027] In this embodiment, the disassembly device 7 includes an outer ring 71, and a slot 72 is opened at the upper end of the outer ring 71 to pass through the upper and lower ends. Four paddles 73 are fixedly connected to the outer surface of the outer ring 71; the four paddles 73 are distributed in a ring shape with equal distances, and the slot 72 is adapted to the shape of the temperature sensor body 1.

[0028] According to the above solution, after the outer collar 71 is sleeved onto the temperature sensor body 1 , the outer collar 71 is rotated to drive the temperature sensor body 1 to rotate, and the temperature sensor body 1 can be disassembled without the need for tools.

[0029] It should be noted that the present invention describes a temperature sensor for a constant-temperature water heater. When the sensor requires protection, the sleeve 31 is attached to the detection end 5, forming a tight threaded connection with the threaded connection portion 2 through its internal internal threads 34. This connection not only enhances structural stability but also allows the pressure plate 33 to effectively compress the sealing ring 12, preventing the risk of the sealing ring 12 falling due to loosening. The sleeve 31 tightly fits the detection end 5 and works in conjunction with the reinforcing ribs 32 to form a solid protective layer. The reinforcing ribs 32 also enhance the structural strength of the sleeve 31, allowing the entire protective device to effectively disperse and absorb forces from external impacts or bumps, thereby preventing damage to the detection end 5 and ensuring the accuracy and service life of the temperature sensor. To disassemble, the outer collar 71 is attached to the outer surface of the temperature sensor body 1. The user simply rotates the four paddles 73 on the outer surface of the outer collar 71, causing the outer collar 71 to rotate with the temperature sensor body 1. The installation and removal process is simplified. Even without professional tools, users can easily complete the installation and removal of the temperature sensor, which improves work efficiency and flexibility of use.
