Description

Technical Field

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

[0002] The temperature sensor used in a constant temperature water heater is a device that can sense the temperature changes inside the water heater and convert this change into an electrical signal output. It is one of the core components of a constant temperature water heater and is usually composed of temperature sensing elements such as thermistors and thermocouples, as well as signal processing circuits.

[0003] Existing temperature sensors for constant temperature water heaters are mainly fixed by threaded connections through threaded blocks and threaded grooves. However, this installation method has certain defects. For example, the installation and removal of the sensor may become difficult due to over-tightening or over-loosening of the threaded connection. Over-tightening may cause damage to the thread, while over-loosening may cause sensor instability or leakage. In addition, the threaded connection may cause mechanical stress to the sensor during the tightening process, which may affect the accuracy and stability of the sensor over a long period of time. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a temperature sensor for a constant temperature water heater to solve the technical problem that the installation method of the traditional temperature sensor for a constant temperature water heater needs to be optimized.

[0005] To achieve the above object, the utility model provides the following technical solution: a temperature sensor for a constant temperature water heater, comprising a water heater housing, a water heater body and a sensor probe, a water pipe is arranged on the outside of the water heater body, a water inlet end and a water outlet end are arranged at both ends of the water pipe, and the outer surface of the water inlet end is detachably connected to the sensor probe through a mounting mechanism;

[0006] The sensor probe includes a mounting seat, a thread groove is arranged inside the mounting seat, a spring groove is opened on the inner wall of the thread groove, a movable plate is slidably connected inside the spring groove, a first spring is arranged on one side of the movable plate, and a second spring is arranged on the other side of the movable plate, and the ends of the first spring and the second spring away from the movable plate are both in contact with the spring groove.

[0007] By adopting the above technical solution, the structure enables the sensor to accurately monitor the temperature of the water inlet end and provide accurate data for the constant temperature control of the water heater. At the same time, the design of the installation mechanism facilitates the disassembly and maintenance of the sensor probe, thereby improving the convenience of maintenance.

[0008] Furthermore, an abutment rod is provided on the inner side of the first spring, and the abutment rod extends to the inside of the thread groove; a push rod is provided on the inner side of the second spring, and the push rod passes through the mounting seat and extends to the outside of the mounting seat.

[0009] By adopting the above technical solution, the design of the abutment rod and the push rod cooperates with the elastic action of the first spring and the second spring to achieve stable movement and locking functions inside the installation mechanism, ensuring the firm installation of the sensor probe.

[0010] Furthermore, a rotating seat is arranged at the front end of the thread groove, a thread block is arranged at the back of the rotating seat, and spring clamping blocks are arranged on both sides of the thread block.

[0011] By adopting the above technical solution, the design of the rotating seat and the threaded block allows the sensor probe to be easily installed to the water inlet end by rotation, while the spring clamp block provides an additional locking function to enhance the stability of the connection.

[0012] Furthermore, the thread block is threadedly connected to the thread groove, the spring clamping block is engaged with the spring groove, and the abutting rod is in abutment with the spring clamping block.

[0013] By adopting the above technical solution, the threaded connection and the snap-fit ​​design together ensure the secure installation of the sensor probe, while the abutment between the abutment rod and the spring block prevents accidental loosening or falling off, thereby improving the reliability of the entire temperature sensor.

[0014] Furthermore, a sensor probe is provided at the rear end of the threaded block, and the sensor probe is fixed inside the water inlet end through a mounting mechanism.

[0015] By adopting the above technical solution, since a sensor probe is provided at the rear end of the threaded block, the sensor probe is fixed to the inside of the water inlet end through a mounting mechanism, thereby ensuring that the sensor probe can fit tightly to the inner wall of the water inlet end, thereby accurately sensing water temperature changes and providing precise data support for the constant temperature control of the water heater.

[0016] Furthermore, two spring blocks are provided, and the two spring blocks are mirror-imaged along the central axis of the threaded block.

[0017] By adopting the above technical solution, the mirror-image arrangement of the two spring blocks increases the stability and reliability of the locking mechanism, and effectively prevents deformation or damage of the mounting seat or the threaded block that may be caused by unilateral force.

[0018] Furthermore, a push ring is slidably connected to the rear end of the mounting seat, and the push ring is sleeved with the mounting seat.

[0019] By adopting the above technical solution, the sliding connection design of the push ring provides a convenient operation point, so that the user can easily unlock the installation mechanism by pushing the push ring, thereby facilitating the disassembly and maintenance of the sensor probe.

[0020] Furthermore, the push ring is used to abut against the push rod, and when the push rod is abutted, it can ensure that the abutment rod can push out the spring block to unlock the thread block and the thread groove.

[0021] By adopting the above technical solution, the unlocking mechanism is simple and efficient, and the sensor probe can be quickly disassembled by pushing the push ring, which greatly improves the operational convenience when repairing or replacing the sensor probe.

[0022] Furthermore, a transmission line is provided on the outer surface of the rotating seat, and the other end of the transmission line is connected to the control mainboard of the water heater.

[0023] By adopting the above technical solution, the design of the transmission line enables the temperature data measured by the sensor probe to be transmitted to the control mainboard of the water heater in real time and accurately, providing important support for the intelligent constant temperature control of the water heater.

[0024] Furthermore, the material of the mounting mechanism is stainless steel, and the material of the water heater shell is aluminum alloy.
