Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a spring connection structure of a temperature controller. Background Art

[0002] With the continuous improvement of modern industrial automation and home intelligence, the accuracy and stability of temperature control systems have become one of the key indicators for measuring equipment performance. Liquid expansion thermostats are widely used in air conditioners, refrigerators, heating equipment and other fields due to their advantages such as sensitive response and compact structure. This type of thermostat drives the mechanical structure through the volume change caused by the change of temperature of the special liquid filled inside, thereby controlling the on and off of the circuit and achieving precise temperature control.

[0003] However, in actual applications, especially when manual intervention is required for troubleshooting or calibration, improper rotation or forceful resetting may damage the precision components inside the thermostat, especially the reed, the core component responsible for the on-off of the circuit. The reed is a key component in the thermostat that directly bears mechanical stress. Even a slight deformation of its structure may lead to poor contact, slow response, and even failure of the entire thermostat, seriously affecting the service life and working efficiency of the equipment.

[0004] Most thermostats on the market today do not adequately consider overload protection caused by manual operation, especially during the downward pressure of the push rod. If there is no necessary buffer space under the reed, it is very easy to cause excessive extrusion and deformation of the reed, thus shortening the product life and increasing maintenance costs. Therefore, it is an urgent need for the industry to develop a new structural design that can ensure the normal working performance of the thermostat and effectively protect the reed from damage caused by improper operation.

[0006] The technical solution adopted by the utility model is: a reed connection structure of a temperature controller, including a ceramic seat, a reed, a push rod, a moving terminal and a static terminal, and also includes a reed seat, one end of the reed is connected to the reed seat, the reed seat and the static terminal are connected to the ceramic seat by bolts, the reed seat includes a flat section, a lower slope and an "L"-shaped section, a downward pressure space is formed between the lower slope and the "L"-shaped section, and the downward pressure space is located directly below the above-mentioned push rod.

[0007] Furthermore, a positioning column is provided on the flat plate segment, and a positioning hole capable of being inserted into the positioning column is provided on one end of the spring sheet.

[0008] Furthermore, the spring sheet below the push rod is provided with an arc-shaped raised section, a through groove is provided on the left side of the arc-shaped raised section, and a positioning long groove for the "L"-shaped section to pass through is provided on the right side.

Enhanced protection mechanism: By setting up a reed seat and a downward pressure space on the reed seat, the direct pressure on the reed during the downward pressure of the push rod is effectively alleviated, which greatly reduces the risk of reed deformation caused by improper human operation or abnormal working conditions, protects the core mechanical components of the thermostat, and extends the overall service life of the product.

[0014] 2. Improve system stability: Reasonable structural layout ensures the stable operation of the thermostat under various working conditions.
