Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, specifically a multi-level adjustable electronic temperature controller. Background Technology

[0002] Multi-level adjustable electronic thermostats are devices with multiple temperature control levels, enabling precise temperature control. They are widely used in home appliances, aquaculture, and industrial fields. Their core features include simple structure, high integration, small size, accurate and flexible temperature control, and easy wiring and operation.

[0003] A search revealed a utility model patent in China with patent publication number CN219320696U, which discloses a multi-level adjustable electronic temperature controller. The controller is roughly described as including a housing, inside which a circuit board is installed. An MCU adjustment relay and a temperature level sensor are mounted on one side of the circuit board. In use, the temperature level is set by rotating a temperature control knob to a specified angle. The temperature level sensor detects the input temperature control level from the knob and transmits the signal to the circuit board to adjust the temperature level. An NTC probe detects the temperature of the heating element load, and the MCU adjusts the on / off state of the relay to control the operation of the heating element load, ensuring that the temperature of the heating element load is within the preset temperature control level range. Within its scope, this product features a simple structure, high integration, small size, accurate and flexible temperature control, and simple wiring and operation. It also offers precise temperature control with multiple temperature levels, effectively controlling temperature rise. It can be used as a low-cost temperature control solution in home appliances, aquaculture, and industry. However, the above device still has some shortcomings. For example, when installing, fixing, disassembling, or repairing the device, tools are needed to remove multiple screws, making direct disassembly and repair inconvenient and time-consuming. Moreover, without the tools to remove the corresponding screws, the device cannot be disassembled, which will delay repairs and may cause some economic losses. Its applicability is limited. Therefore, we propose a multi-level adjustable electronic temperature controller. Utility Model Content
