[0048] It can be understood that the control device, such as the temperature controller, also known as the temperature controller, temperature control switch, temperature protector, is a series of automatic control elements that can change according to the temperature change of the working environment, and the physical deformation occurs inside the switch, thereby producing a series of automatic control elements. On-off action, it is a device for monitoring and controlling the temperature of the environment. At present, the control device usually needs to monitor the environmental temperature, and the temperature and humidity sensor in the control device is usually in a closed space, and then the algorithm compensation method is used to calculate, which causes the measured data parameters and the actual temperature and humidity parameters to have a certain error, affecting the accuracy of the detection result.

[0049] For this purpose, referring to Figures 1 to 3 The present application provides a control device 10. The control device 10 is applied to a temperature control device (not shown) to realize temperature control of the temperature control device. Figure 1 The schematic diagram of the control device 10 of an embodiment of the present application is shown in Figure 2 For Figure 1An exploded schematic view of the control device 10 in one perspective, Figure 3 For Figure 2 An exploded schematic view of the control device 10 in another perspective.

[0050] The temperature control device comprises a device host (not shown) and the control device 10 of the present application. The control device 10 is in communication connection with the device host. In the present application, the control device 10 can regulate the relevant parameters of the device host so that the relevant parameters of the device host can meet the use requirements. The relevant parameters herein include but are not limited to temperature parameters, and can also be humidity or other parameters, etc. The present application only takes the temperature control of the device host by the control device 10 as an example for illustration.

[0051] In this way, the control device 10 can receive the feedback signal of the device host, and also can send a control signal to the device host to realize the temperature regulation of the device host. In the present application, the device host includes but is not limited to floor heating, air conditioning, water heater, central fresh air system, etc. household appliances, and the control device 10 can adjust the temperature of the device host so that the temperature of the device host can meet the use requirements of the user. Of course, the device host can also include industrial control devices and other devices that need to regulate the temperature.

[0052] In the present application, the control device 10 is mainly a temperature controller. Of course, in other embodiments of the present application, the control device 10 can also be other structures or devices that can realize control by converting alternating current into direct current. The present application only takes the control device 10 as a temperature controller as an example for illustration.

[0053] The control device 10 of the present application can allow the air of the outside world to enter and exit, so as to detect the temperature and humidity of the air in real time, without using algorithm compensation calculation, avoiding the deviation of the measured data parameters and the actual temperature and humidity parameters, ensuring that the measured data is consistent with the actual data, and further ensuring the accuracy of the detection result.

[0054] Referring to Figures 1 to 7 In an embodiment, the control device 10 comprises a first control module 100 and a second control module 200. The first control module 100 comprises a main body shell 110, the main body shell 110 has a flow channel groove 111 arranged in recess, and an air inlet hole 112 and an air outlet hole 113 located at opposite ends of the flow channel groove 111. The air inlet hole 112 and the air outlet hole 113 penetrate from the outside of the main body shell 110 to the inner cavity of the main body shell 110 and communicate with the flow channel groove 111. The second control module 200 is arranged on one side of the first control module 100 and covers the flow channel groove 111 to form an air flow channel 101. The air flow channel 101 communicates with the outside of the main body shell 110 through the air inlet hole 112 and the air outlet hole 113. Figure 4 For Figure 1A plan view of the control device 10 shown, Figure 5 A plan view of the control device 10 shown, Figure 4 A sectional view of the control device 10 shown at A-A, Figure 6 A sectional view of the control device 10 shown at A-A, Figure 5 A sectional view of the control device 10 shown at A-A, Figure 7 A sectional view of the control device 10 shown at A-A, Figure 3 A sectional view of the control device 10 shown at A-A.

[0055] The first control module 100 and the second control module 200 are main components of the control device 10, and the second control module 200 is arranged at one end of the first control module 100 so that one end of the first control module 100 is closed. Specifically, the first control module 100 comprises a main body shell 110, which is an external shell of the first control device 10 and also an external shell of the entire control device 10. One end of the main body shell 110 has an opening, and the second control module 200 is arranged in the main body shell 110 and covers the opening of the main body shell 110.

[0056] Further, the main body shell 110 has a flow channel groove 111 arranged in a recess, and the main body shell 110 further has an air inlet hole 112 and an air outlet hole 113 that penetrate from the outside to the inner cavity, the air inlet hole 112 and the air outlet hole 113 are arranged at opposite ends of the flow channel groove 111 and communicate with the flow channel groove 111. The air inlet hole 112 and the air outlet hole 113 can communicate the flow channel groove 111 with the outside of the main body shell 110.

[0057] After the second control module 200 covers the opening of the main body shell 110, the second control module 200 can cover the flow channel groove 111. At this time, the second control module 200 is equivalent to the upper cover of the flow channel groove 111, and the second control module 200 can be arranged with the flow channel groove 111 to form an air flow channel 101.

[0058] The air from the outside can enter the air flow channel 101 through the air inlet hole 112 and flow along the air flow channel 101, and then flow out of the main body shell 110 through the air outlet hole 113. In this way, the air from the outside can circulate into the air flow channel 101 through the air inlet hole 112 and the air outlet hole 113, and the space where the air flow channel 101 is located is no longer a closed space.

[0059] When the control device 10 is working, the control device 10 can detect the temperature and humidity values of the air in the air flow channel 101 in real time. Since the air from the outside can enter the air flow channel 101 in real time through the air inlet hole 112, the control device 10 can detect the temperature and humidity values of the air in the air flow channel 101, which are the temperature and humidity values in the external environment.

[0060] In this way, the control device 10 obtains the temperature and humidity values in the external environment by detecting the temperature and humidity of the air in the air flow channel 101, without using algorithm compensation calculation, so as to avoid deviation of the measured data parameters from the actual temperature and humidity parameters, ensure that the measured data is consistent with the actual data, and further ensure the accuracy of the detection results.

[0061] Referring to Figures 3 to 7 In an embodiment, the flow channel groove 111 is located at one side edge of the main body shell 110. In this way, the flow channel groove 111 can be conveniently communicated with the air inlet hole 112 and the air outlet hole 113. Of course, in other embodiments of the present application, the flow channel groove 111 can also be arranged at the middle region of the main body shell 110 and surrounded by the plate member.

[0062] Referring to Figures 2 to 9 In an embodiment, the second control module 200 includes a first main control board 210 arranged in the main body shell 110 and a display module 220 arranged at the side of the first main control board 210 away from the first control module 100. The display module 220 is in abutment with the surface of the first main control board 210 facing the display module 220, and the first main control board 210 and the display module 220 surround the flow channel groove 111 to form the air flow channel 101. Figure 8 As shown in Figure 1 FIG. 4 is a schematic view of the control device 10 without the display module 220, Figure 9 As shown in Figure 8 FIG. 5 is a perspective view of the control device 10.

[0063] The first main control board 210 is a control board, which is arranged in the main body shell 110. The display module 220 is arranged in the opening of the main body shell 110 and can cover the first main control board 210. That is, the display module 220 is located outside the first main control board 210 to protect the first main control board 210. The first main control board 210 is electrically connected with the display module 220, and can output corresponding control signals and display them through the display module 220 for the user to use.

[0064] In addition, the main control board is in contact with the inner wall of the main body shell 110, and the display module 220 is also in abutment with the surface of the main control board. At this time, the display module 220 and the first main control board 210 can cover the flow channel groove 111 to surround the flow channel groove 111 to form the air flow channel 101, and the control device 10 is communicated with the external environment through the air flow channel 101, the air inlet hole 112 and the air outlet hole 113.

[0065] Meanwhile, since the main control board abuts against the inner wall of the display module 220 and the main housing 110, the space of the control device 10, except for the airflow channel 101, can be a sealed space. In this way, outside air can enter the airflow channel 101 through the air inlet 112 and then flow out of the airflow channel 101 through the air outlet 113.

[0066] At the same time, no air will enter or exit in the sealed space, thereby preventing the various electrical components on the first main control board 210 from coming into contact with the air, preventing dust and other substances from accumulating on the first main control board 210, ensuring that the first main control board 210 is in a sealed environment as much as possible, thereby ensuring the performance of the first main control board 210.

[0067] See Figure 3 and Figure 4 In one embodiment, the first control module 100 further includes a temperature and humidity sensor 120 disposed on the main housing 110. The temperature and humidity sensor 120 is at least partially located in the flow channel groove 111 and is disposed near the air inlet 112. The temperature and humidity sensor 120 is capable of detecting the temperature and humidity values ​​of the spatial environment in which the control device 10 is located.

[0068] The temperature and humidity sensor 120 is disposed in the main housing 110, and the temperature and humidity sensor 120 is at least partially located in the flow channel groove 111. In this way, after the outside air enters the airflow channel 101 through the air inlet 112, the air can come into contact with the temperature and humidity sensor 120, and the temperature and humidity sensor 120 can detect the temperature and humidity values ​​of the air in the airflow channel 101.

[0069] In this way, the temperature and humidity sensor 120 can detect the temperature and humidity values ​​of the air entering the airflow channel 101 in real time. These temperature and humidity values ​​can accurately reflect the temperature and humidity of the space environment where the control device 10 is located, without the need for algorithm compensation calculation, ensuring that the measured data is consistent with the actual data, and thus ensuring the accuracy of the detection results.

[0070] Furthermore, the temperature and humidity sensor 120 is electrically connected to the first main control board 210. In this way, the temperature and humidity sensor 120 can feed back the detected temperature and humidity values ​​to the first main control board 210. The first main control board 210 can accurately monitor the temperature and humidity of the space environment where the control device 10 is located, and adjust it when the specific temperature and humidity values ​​deviate from the set values, so that the indoor temperature and humidity can meet the usage requirements.

[0071] Furthermore, the temperature and humidity sensor 120 is positioned close to the air inlet 112. That is, the temperature and humidity sensor 120 is located at the air inlet end of the airflow channel 101. In this way, the air entering the airflow channel 101 through the air inlet 112 first comes into contact with the temperature and humidity sensor 120, and then is discharged along the airflow channel 101 through the air outlet 113, so as to ensure the accuracy of the detection results of the temperature and humidity sensor 120.

[0072] It can be understood that the first main control board 210 generates heat during operation, and the heat is dissipated towards the air flow channel 101, so that the temperature of the air in the air flow channel 101 is increased. If the temperature and humidity sensor 120 is located between the air inlet hole 112 and the air outlet hole 113 or close to the air outlet hole 113, the temperature and humidity value detected by the temperature and humidity sensor 120 deviates from the actual temperature and humidity value of the air outside, affecting the accuracy of the detection result.

[0073] Therefore, the temperature and humidity sensor 120 is arranged close to the air inlet hole 112, so that the temperature and humidity sensor 120 can contact the air not absorbing heat at the air inlet hole 112, so that the temperature and humidity value detected by the temperature and humidity sensor 120 is consistent with the actual temperature and humidity value outside, ensuring the accuracy of the detection result of the temperature and humidity sensor 120.

[0074] Referring to Figures 2 to 9 In an embodiment, the temperature and humidity sensor 120 is arranged at the edge of the first main control board 210. In this way, the space occupied by the temperature and humidity sensor 120 in the thickness direction of the first main control board 210 can be reduced, the thickness size of the control device 10 can be reduced, and the temperature and humidity sensor 120 can be prevented from affecting the heat dissipation of the first main control board 210. In addition, the heat of the first main control board 210 can also be prevented from being conducted to the temperature and humidity sensor 120, so as to ensure the reliability of the operation of the temperature and humidity sensor 120.

[0075] Referring to Figures 5 to 9 In an embodiment, the first main control board 210 partially blocks the flow channel groove 111. That is, the edge of the first main control board 210 extends into the flow channel groove 111, and there is a certain gap between the edge of the first main control board 210 and the side wall of the main body shell 110. In this way, the first main control board 210 can partially block the flow channel groove 111, so as to prevent the heat generating element 211 (mentioned below) on the first main control board 210 from being close to the temperature and humidity sensor 120, and ensure the reliability of the operation of the temperature and humidity sensor 120.

[0076] Referring to Figures 2 to 9 In an embodiment, the first main control board 210 has a heat generating element 211, and the heat generating element 211 is arranged on the side of the first main control board 210 away from the flow channel groove 111. There is a predetermined gap between the heat generating element 211 and the temperature and humidity sensor 120, and the heat generating element 211 is arranged close to the air outlet hole 113 of the main body shell 110.

[0077] The heat generating element 211 is a heat source (heat generating chip) on the first main control board 210, such as a WIFI chip. When the first main control board 210 operates, the heat generating element 211 generates a large amount of heat. If the heat generating element 211 is arranged close to the temperature and humidity sensor 120, the accuracy of the detection result of the temperature and humidity sensor 120 will be affected.

[0078] To this end, the application defines that there is a preset distance between the heating element 211 and the temperature and humidity sensor 120, so as to reduce the heat generated by the heating element 211 when working to the temperature and humidity sensor 120 as much as possible, and ensure the accuracy of the detection result of the temperature and humidity sensor 120.

[0079] At the same time, the heating element 211 is located on the surface of the first main control plate 210 away from the flow channel groove 111, and is arranged close to the air outlet hole 113. The heat generated by the heating element 211 can be conducted to the air in the air flow channel 101 through the first main control plate 210, so as to increase the temperature of the air in the air flow channel 101, and form the gravity difference between the inside and outside air of the air flow channel 101, and increase the suction of the air flow channel 101.

[0080] It can be understood that the application arranges the heating element 211 on the first main control plate 210, and the heating element 211 conducts heat to the air flow channel 101 through the first main control plate 210, based on the principles of thermodynamics and aerodynamics, so that the outside air can enter the air flow channel 101 through the air inlet hole 112, and then be discharged through the air outlet hole 113.

[0081] When the heating element 211 conducts heat to the air flow channel 101, a certain negative pressure is formed in the air flow channel 101 due to thermal expansion and contraction, so that the outside air can enter the air flow channel 101 through the air inlet hole 112, and the temperature of the air in the air flow channel 101 rises after absorbing heat, and then the heat-absorbed air can flow in the air flow channel 101, so that the air in the air flow channel 101 can be discharged through the air outlet hole 113, so that the outside air can freely enter and exit the air flow channel 101, and the temperature and humidity sensor 120 can detect the temperature and humidity value of the outside air in real time.

[0082] It is worth noting that, Figure 7 and Figure 10 The height direction shown is actually the direction when the control device 10 is installed, and the control device 10 is installed on the wall along the height direction, and the air flow channel 101 extends along the height direction.

[0083] In this way, the air flow channel 101 can form a chimney structure through the air inlet hole 112 and the air outlet hole 113, based on the principles of thermodynamics and aerodynamics, so that the outside air can enter the air flow channel 101 through the air inlet hole 112, and then be discharged through the air outlet hole 113, so that the outside air can circulate in the air flow channel 101.

[0084] In an embodiment, the first main control board 210 further has a heat conduction member, which is arranged on the portion of the first main control board 210 corresponding to the flow channel groove 111.

Of course, the area of the first main control board 210 corresponding to the flow channel groove 111 can also be windowed, so that the copper wire in the first main control board 210 is exposed to form a heat conduction member, so as to increase the heat conduction effect of the first main control board 210 to the airflow channel 101.
