[0040] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7 The embodiment provides a heat insulation structure of a temperature controller, which comprises a shell 10 and a circuit board 102. One side of the shell 10 is open, and a heat insulation plate 101 is arranged in the shell 10 and connected to the side wall of the shell 10 at the head and tail to form a heat insulation area 1011. The circuit board 102 is arranged in the shell 10, a sensor 1021 is arranged on the circuit board 102, the sensor 1021 is arranged in position with the heat insulation area 1011, a plurality of hollow holes 1022 are arranged on the circuit board 102 and arranged in position at the head and tail of the side edge of the circuit board 102, and the area of the circuit board 102 divided by the plurality of hollow holes 1022 is a partition area 1023 for mounting the sensor 1021.

[0041] Specifically, the sensor 1021 can be a DHT11 temperature and humidity sensor, which is used for detecting the temperature and humidity in the environment, the circuit board 102 is arranged in the shell 10 and placed on the top surface of the heat insulation area 1011, and the heat insulation plate 101 can support and stabilize the circuit board 102 to a certain extent. The sensor 1021 is accommodated in the heat insulation area 1011 and is suspendedly connected to the circuit board 102. On the one hand, the heat insulation plate 101 is used for surrounding the independent heat insulation area 1011 in the shell 10 to accommodate the sensor 1021, so that the internal heat can be isolated from being conducted to the sensor 1021, and the precision of the sensor 1021 in detecting the temperature and humidity is prevented from being affected by the heat generation of other electronic components of the temperature controller or other factors; on the other hand, since the circuit board 102 is prone to heat generation after being powered on, the sensor 1021 is mounted on the partition area 1023 surrounded by the plurality of hollow holes 1022 on the circuit board 102, and the hollow structure of the hollow hole 1022 can isolate heat transfer, so that the heat transferred along the circuit board 102 to the sensor 1021 can be reduced, thereby reducing the influence of the heat generated by the circuit board 102 on the sensor 1021, and further improving the precision of the sensor 1021 in detecting the temperature and humidity.

[0042] As Figure 3 ,Figure 4 , Figure 5 and Figure 6 As shown in

[0043] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the heat insulation area 1011 is arranged at the corner of the shell 10; and the plurality of heat dissipation holes 103 are arranged on the two side walls at the corner of the shell 10 and form the convection holes.

[0044] Specifically, the plurality of heat dissipation holes 103 are arranged on one side wall at the corner of the shell 10, and the plurality of heat dissipation holes 103 are arranged on the other side wall at the corner of the shell 10, and the heat dissipation holes 103 on the two adjacent side walls form the convection holes, so as to enhance the circulation of the air in the heat insulation area 1011, realize the circulating flow of the air in the heat insulation area 1011, and further improve the heat dissipation effect and speed in the heat insulation area 1011, and improve the accuracy of the sensor 1021 in detecting the temperature and humidity.

[0045] In this embodiment, the outer surface of the heat insulation plate 101 is provided with a heat insulation layer (not shown in the figure). The heat insulation layer can be a heat insulation coating or a heat insulation film. For example, the heat insulation layer can be GN-101A nano-composite zirconium oxide agglomerate thermal spraying material, which has good heat insulation and cooling effect, can improve the effect of isolating the internal heat conduction into the heat insulation area 1011, and further ensure the accuracy of the sensor 1021 in detecting the temperature and humidity.

[0046] As shown in Figure 3 and Figure 7 In this embodiment, a plurality of limiting grooves 1024 are arranged on one side edge of the circuit board 102, and a limiting block matched with the limiting grooves 1024 can be arranged on the inner side wall of the shell 10. The limiting block and the limiting grooves 1024 are clamped with each other, so as to limit the circuit board 102 and increase the stability of the circuit board 102 installed in the shell 10. A plurality of avoiding grooves 1025 are arranged on the other side edge of the circuit board 102, and the avoiding grooves 1025 are used for avoiding the circuit of the electronic components in the thermostat.

[0047] As shown in Figure 8As shown, the heat dissipation hole 103 on one side wall at the corner in the embodiment is provided with a first horn mouth 1031 gradually narrowing from the outer wall of the shell 10 to the inner wall of the shell 10; the heat dissipation hole 103 on the other side wall at the corner is provided with a second horn mouth 1032 gradually increasing from the outer wall of the shell 10 to the inner wall of the shell 10.

[0048] Specifically, since the cross-sectional area of the airflow channel formed by the first horn mouth 1031 and the second horn mouth 1032 is variable, the airflow speed will correspondingly increase when the cross-sectional area of the airflow channel decreases, therefore, the cross-sectional area of the airflow channel of the first horn mouth 1031 gradually narrows from the outside of the shell 10 to the inside of the shell 10, which can accelerate the speed of the external cold air flowing into the heat insulation area 1011; the cross-sectional area of the airflow channel of the second horn mouth 1032 gradually narrows from the inside of the shell 10 to the outside of the shell 10, which can accelerate the speed of the hot air in the heat insulation area 1011 being discharged. In this way, the horn-shaped heat dissipation hole 103 can accelerate the speed of the cold and hot air circulation in the heat insulation area 1011, and further improve the speed and effect of the heat dissipation of the temperature controller.

[0049] As shown in Figure 5 and Figure 6 As shown, the other side of the shell 10 opposite to the opening is provided with an observation opening 104, through which the information displayed on the display screen installed on the shell 10 can be observed, and the display screen or the operation button can be conveniently pointed and operated.
