[0004] Thermostat generally uses NTC thermistor or thermocouple as temperature detection element. Its principle is: design NTC thermistor or thermocouple into the corresponding circuit. When the NTC thermistor or thermocouple changes with temperature, it will produce corresponding voltage and current changes. Then the microcontroller detects and quantifies the changed voltage and current, and performs corresponding control. Digital temperature controller has the characteristics of high accuracy, good sensitivity, intuitiveness and easy operation.

[0005] Thermostats are widely used in various household appliances, such as refrigerators, water dispensers, water heaters, coffee makers, etc. The quality of the thermostat directly affects the safety, performance, and life of the entire machine, and is a very critical component.

Temperature feedback is then performed, and the temperature is controlled and adjusted through the temperature control protector to achieve a whole process of operation. However, due to the temperature measurement environment in some areas, the probe needs to be bent before it can be inserted for sensing, so it is necessary to design a bendable probe structure to meet the temperature control sensing requirements of the temperature controller.

[0030] It should be further explained that a display screen and operation buttons are provided on the front of the temperature controller body 1, and a symmetrically distributed shaft seat 2 is fixed to the upper end of the front side one centimeter away from the edge. A damping shaft 21 made of hard plastic material is rotatably installed in the two shaft seats 2. The damping shaft 21 increases the friction with the shaft seat 2, so that the rotation angle of the baffle frame 22 can be fixed when rotating.

[0031] It should be further explained that a baffle frame 22 covering the display screen and operation buttons is provided on the front of the thermostat body 1. The baffle frame 22 and the damping shaft 21 are arranged through, and the connecting part is fixed by filling and bonding with resin glue, so that the baffle frame 22 can cooperate with the damping shaft 21. The baffle frame 22 is made of transparent high-strength material, and a pull head 23 is integrally connected to the front of the baffle frame 22 along the vertical center axis. The baffle frame 22 can protect the display and operation buttons arranged on the front of the thermostat body 1 from touch.

[0032] It should be further explained that the back of the thermostat body 1 is symmetrically provided with mounting brackets 3, and circular mounting holes 31 are opened on the mounting brackets 3. The inner wall surface of the mounting hole 31 is a smooth surface or a threaded surface. The mounting brackets 3 can be fixed on the wall by rivets or threaded nails to ensure that the thermostat body 1 is stably fixed on the wall.

[0033] It should be further explained that the mounting bracket 3 and the back of the shell of the thermostat body 1 are installed by means of screws 32. The screws 32 pass through the mounting bracket 3 and a through hole for sliding sleeve is provided at the position. The back of the shell of the thermostat body 1 is provided with a threaded groove into which the screws 32 are inserted, so that the mounting bracket 3 and the thermostat body 1 can be stably installed.

When the probe structure needs to be bent, the bellows 16 is bent so that the sensing head 15 and the probe interface 13 can form a bending angle. At the same time, the connecting wire 14 used for the sensing head 15 and the probe interface 13 will not be excessively damaged, and the bending of the sensing head 15 can be positioned.

[0038] When stable handheld probe structure operation is required, the half-set positioning ring 18 is covered on the upper and lower notches 17 of the probe interface 13. The notch 17 can limit the position of the positioning ring 18. The straight column screw 42 penetrates the two adjacent first rings 4 and second rings 41 on one side, and the nut 43 is threadedly connected with the straight column screw 42 to achieve a stable connection between the positioning ring 18 and the probe interface 13. The worker can hold the hand with force through the handle bar 19.

[0039] During normal detection, workers can peek at the contents of the display screen through the baffle frame 22 made of transparent plastic material. The baffle frame 22 can provide anti-touch protection for the display screen and the operating buttons. When the operating buttons need to be operated, the baffle frame 22 can be flipped by rotating the damping shaft 21 in the shaft seat 2 and pulling the pull head 23 by hand. The damping effect of the damping shaft 21 allows the baffle frame 22 to be positioned at the flipping angle.
