[0002] With the development of smart homes, smart switches have gradually been used to replace traditional mechanical switches due to their intelligence, diversified control and convenient operation. As the trigger device of smart homes, smart switches play a very critical role in the entire system. More and more users choose smart switches to control indoor electrical equipment during decoration.

[0003] In addition to remote control, one-button full opening, lamp brightness and color temperature adjustment, temperature adjustment, and associated smart scenes, some smart switches also integrate other functions, such as detecting temperature and humidity, displaying time and weather, etc.

[0004] In the installation process of existing wall switches, in order to prevent the bottom shell from being damaged due to excessive locking force of long bolts, a metal mounting piece is often set around the bottom shell, and the mounting piece is fixedly connected to the bottom shell. During installation, the long bolts lock the mounting piece to the dark box, and the bottom shell is indirectly fixed to the dark box through the mounting piece, thereby preventing the bottom shell from being damaged. However, since the mounting piece is generally made of sheet metal, it has low rigidity and is easily deformed under the action of the locking force of the long bolts. The bottom shell will deform along with the mounting piece, causing the position of the power circuit board inside the bottom shell to change. Since the power circuit board and the control circuit board are generally connected by pin and female headers or spring conductive pins, changes in the position of the power circuit board will cause a connection failure between the power circuit board and the control circuit board.

[0051] Existing smart switches with temperature and humidity detection functions have high heat generation, and the heat generation will change in real time with changes in working conditions, which will seriously affect the accuracy of temperature and humidity detection. How to improve the accuracy of detecting ambient temperature and humidity has become an urgent problem to be solved for smart switches.

[0052] In order to improve the problem of inaccurate detection of ambient temperature and humidity by existing intelligent switches, according to the first aspect of the present invention, a switch device 100 is provided, which is suitable for being installed on a wall. Figure 1-Figure 16 , the switch device 100 provided by the present invention will be specifically explained. Figure 1-Figure 11 As shown, the switch device 100 includes a panel housing 11 and a first sensor 12. The first sensor 12 is arranged inside the panel housing 11 and is used to detect temperature and / or humidity. Fig.10As shown, the panel housing 11 has a first bottom wall 111, the distance between the first sensor 12 and the first bottom wall 111 is less than 5mm, and the first bottom wall 111 is provided with an air vent 112 at the position corresponding to the first sensor 12; when the switch device 100 is installed on the wall, the first bottom wall 111 is located at the bottom of the panel housing 11, and the air vent 112 is open downward. Among them, the switch device 100 can be understood as a device that can perform a switch action in response to a user operation, or a device that can control other devices to perform a switch action in response to a user operation. In some exemplary embodiments, the switch device 100 can be a wall switch, a thermostat, etc. The first sensor 12 can be understood as a temperature sensor, a humidity sensor, or a sensor that can detect temperature and humidity at the same time. In a specific embodiment, the first sensor 12 adopts a temperature and humidity sensor of model GXHT30 of Zhongke Galaxy Core Technology.

[0053] Since the part of the switch device 100 that generates the most heat is located in the center, and heat has the physical property of moving upward, the switch device 100 provided by the utility model sets the first sensor 12 at a position close to the bottom of the panel housing 11, which is not only far away from the part that generates the most heat, but also avoids the movement path of heat, thereby reducing the impact of the heating of the switch device 100 on the temperature and humidity detection, and improving the accuracy of the detection of the first sensor 12. In addition, a vent hole 112 is provided within a distance of 5mm below the first sensor 12, and the vent hole 112 runs through both sides of the panel housing 11, so that the temperature and humidity at the location of the first sensor 12 are closer to the ambient temperature and humidity, thereby improving the accuracy of the detection of the first sensor 12. In a preferred embodiment, the distance between the first sensor 12 and the first bottom wall 111 is 1.2mm.

[0054] It is worth noting that the air vent 112 is open downward, which has the following beneficial effects: (1) Since heat has the physical property of moving upward, the temperature and humidity below the switch device 100 are closer to the ambient temperature and humidity. The air vent 112 is open downward, which can facilitate the air below to enter the air vent 112, thereby improving the accuracy of temperature and humidity detection; (2) The air vent 112 is open downward, making it difficult for dust to fall into the air vent 112; (3) When multiple switch devices 100 are installed side by side, the air vent 112 will not be blocked by the switch devices 100 on the left and right sides.

[0055] Furthermore, if Figure 6-Figure 10As shown, the panel housing 11 is provided with a control circuit board 13, and the first sensor 12 is electrically connected to the control circuit board 13; the panel housing 11 has a first side wall 113, and when the switch device 100 is installed on the wall, the first side wall 113 is located at the side of the panel housing 11; the distance between the first sensor 12 and the first side wall 113 is less than 3mm, so that the first sensor 12 is arranged at the corner of the panel housing 11. Since the part with the highest heat generation of the switch device 100 is located at the center, the first sensor 12 is arranged at the corner of the panel housing 11 to be away from the part with the highest heat generation, reducing the influence of heat generation on the first sensor 12, so that the detection accuracy of the first sensor 12 is improved. Among them, the control circuit board 13 is a weak current circuit board, which can receive and process the electrical signal of the first sensor 12 to obtain temperature and humidity data. The first side wall 113 can be understood as the side wall on the left or right side of the panel housing 11. In a preferred embodiment, the distance between the first sensor 12 and the first side wall 113 is 1.4mm.

[0056] Furthermore, if Figure 1 , Figure 2 and Figure 8 As shown, the panel housing 11 is provided with a screen 14, and the screen 14 is electrically connected to the control circuit board 13; since the screen 14 generates a large amount of heat when it is lit, and the heat is mainly concentrated in the display area 141 of the screen 14, the display area 141 is Figure 1 and Figure 2 The area surrounded by the middle dashed line is to reduce the effect of the heating of the screen 14 on the first sensor 12. Figure 8 As shown, a plane parallel to the control circuit board 13 is used as a projection plane, and the display area 141 of the screen 14 is projected on the projection plane to form a first projection pattern 142 ( Figure 8 The first sensor 12 is projected on the projection plane to form a second projection pattern (not shown in the figure), and the first projection pattern 142 does not overlap with the second projection pattern, thereby reducing the heat generated by the display area 141 and being transferred to the first sensor 12. Furthermore, in addition to the screen 14, another source of heat generation in the switch device 100 is the electronic components on the circuit board. In order to reduce the impact of the heat generated by the electronic components on the first sensor 12, in this embodiment, the control circuit board 13 is projected on the projection plane to form a third projection pattern (not shown in the figure), wherein the third projection pattern does not overlap with the second projection pattern, thereby reducing the heat generated by the control circuit board 13 and being transferred to the first sensor 12.

[0057] In some embodiments, Figure 3 and Fig.15As shown, the switch device 100 further includes a bottom shell 3, a power circuit board 31 is arranged inside the bottom shell 3, and the power circuit board 31 is connected to the control circuit board 13 through a pin header 131 and a female header 311; wherein the power circuit board 31 is connected to 220V strong electricity, and a power module is arranged on the power circuit board 31, and the power module includes a transformer 318, and the power module can convert strong electricity into weak electricity, thereby providing power for the control circuit board 13. In order to reduce the influence of the heating of the power circuit board 31 on the first sensor 12, in this embodiment, an isolation plate 5 is arranged between the power circuit board 31 and the control circuit board 13, and the isolation plate 5 is covered on the bottom shell 3, and the power circuit board 31 is contained between the bottom shell 3 and the isolation plate 5, so that the isolation plate 5 can isolate part of the heat of the power circuit board 31 inside the bottom shell 3, reduce the heat transfer to the panel housing 11, and reduce the influence of the power circuit board 31 on the detection accuracy of the first sensor 12. A mounting member 4 is arranged around the bottom shell 3, and the panel shell 11 is detachably connected to the mounting member 4. It is worth mentioning that the isolation plate 5 also has an electrical isolation function, so that when the panel shell 11 is removed, the power circuit board 31 will not be exposed to the outside, thereby reducing the risk of electric shock.

[0058] Further, the power circuit board 31 is projected on the projection plane to form a fourth projection pattern (not shown in the figure), and the fourth projection pattern does not overlap with the second projection pattern, thereby reducing the heat transfer from the power circuit board 31 to the first sensor 12. Further, as Fig.13 and Fig.14 As shown, the bottom shell 3 is surrounded by mounting parts 4, and the mounting parts 4 are metal sheet metal parts, which are fixed to the bottom shell 3 by clamping. Since the mounting parts 4 are installed close to the wall, the temperature of the mounting parts 4 is closer to the ambient temperature; the mounting parts 4 are projected on the projection plane to form a fifth projection figure (not shown in the figure), and the second projection figure is included in the fifth projection figure, so that the temperature detected by the first sensor 12 is closer to the ambient temperature.

Among them, the side of the first sensor 12 can be understood as being close to the first sensor 12 and arranged in parallel with the first sensor 12. In this embodiment, as Figure 7 and Fig.10 As shown, the first sensor 12 is arranged at the lower right corner of the panel housing 11, the right side of the first sensor 12 is close to the first side wall 113, the lower side is close to the first bottom wall 111, and a heat-insulating foam 151 is arranged on the upper side and the left side respectively, which is used to prevent the heat in the center of the panel housing 11 from being transferred to the first sensor 12, and the heat-insulating foam 151 can prevent part of the heat generated by the screen 14 from being transferred to the first sensor 12, so that the detection accuracy of the first sensor 12 is higher. The heat-insulating foam 151 is made of EVA die-cut material.

[0061] In some embodiments, Fig.10 and Fig.11 As shown, an isolation space 16 is provided between the middle shell 19 and the panel shell 11 at a position corresponding to the first sensor 12, and the first sensor 12 is accommodated in the isolation space 16, wherein the isolation space 16 can be understood as an accommodation space formed by the middle shell 19 and the panel shell 11, and the isolation space 16 can cover the first sensor 12 to reduce the heat transfer from the center of the panel shell 11 to the first sensor 12. Furthermore, the air vent 112 is connected to the isolation space 16, so that the temperature and humidity in the isolation space 16 are closer to the ambient temperature and humidity.

The first cable 121 is attached to the panel housing 11 at the position corresponding to the first sensor 12.

[0063] Furthermore, if Figure 4 and Fig.10As shown, the middle shell 19 is fixedly connected to the panel shell 11 by a plurality of connecting bolts 192, wherein one of the connecting bolts 192 is arranged at the position of the second isolation rib 191, thereby enhancing the connection stability at the position of the second isolation rib 191, so that the positional relationship between the first sensor 12, the isolation space 16 and the thermal insulation foam 151 is more stable. The panel shell 11 is embedded with a knurled nut column 115 adapted to the connecting bolt 192 at the corresponding position of each connecting bolt 192.

The proximity sensor 132 is connected to the control circuit board 13 through the third cable 1321, and the third cable 1321 passes through the panel housing 11. The proximity sensor 132 adopts a sensor model LTR-X1503, which integrates light intensity detection and proximity sensing functions, can emit infrared light of a specified wavelength to the outside, and detect whether an object is close to the switch device 100 based on the infrared light reflection principle. When the distance between the object and the switch device 100 is less than a preset distance, the switch device 100 controls the screen 14 to light up or switch the display content. Figure 6 As shown, the microphones 133 are disposed below the top wall of the panel housing 11 , and sound guide holes 118 are formed through the top wall of the panel housing 11 at positions directly opposite to the microphones 133 .

[0068] like Figure 6 and Figure 7 As shown, the control circuit board 13 is provided with a main control module 135 and a wireless communication module 134. The main control module 135 is electrically connected to the screen 14, the proximity sensor 132, the first sensor 12, and the wireless communication module 134. The main control module 135 can receive electrical signals from the proximity sensor 132, the first sensor 12, the wireless communication module 134, and the screen 14, and the main control module 135 can control the screen 14 to display content and control the wireless communication module 134 to send signals to the outside. The wireless communication module 134 integrates a Bluetooth communication module and a WIFI communication module. The wireless communication module 134 is electrically connected to a patch antenna 1341, and the patch antenna 1341 is attached to the side wall of the panel housing 11 to prevent the signal of the wireless communication module 134 from being shielded by the screen 14 and the control circuit board 13. Furthermore, the lower left corner and the upper right corner of the control circuit board 13 are fixedly connected to the panel housing 11 by circuit board bolts 136 respectively, and the panel housing 11 is embedded with a knurled nut column 115 compatible with the circuit board bolt 136 at the corresponding position of the circuit board bolt 136, and the circuit board bolt 136 is connected to the knurled nut column 115.

[0069] In some embodiments, Fig.10As shown, the diameter of the vent hole 112 is greater than 2 mm, so that the air outside the panel housing 11 can enter the vent hole 112, thereby improving the detection accuracy of the first sensor 12. In a specific embodiment, the vent hole 112 is constructed as a tapered hole with a small top and a large bottom, and the diameter of the upper end is 3 mm and the diameter of the lower end is 3.1 mm.

[0070] like Figure 3 As shown, the bottom shell 3 is surrounded by a metal mounting member 4, which is fixedly connected to the bottom shell 3 and fixedly connected to the dark box 6 by long screws. Since the mounting member 4 has low rigidity, it is easy to deform under the action of the locking force of the long bolt 451, and the bottom shell 3 will deform along with the mounting member 4, resulting in a change in the position of the power circuit board 31 inside the bottom shell 3. Since the power circuit board 31 and the control circuit board 13 are connected through the pin header 131 and the female header 311, a change in the position of the power circuit board 31 will cause a connection failure with the control circuit board 13. In order to improve the problem of easy deformation of the sheet metal and the bottom shell 3, in some embodiments, such as Figure 3 , Figure 12-14 As shown, the switch device 100 includes a panel assembly 1, a bottom shell 3, and a mounting member 4 arranged around the bottom shell 3, wherein the mounting member 4 is formed separately from the bottom shell 3; wherein the mounting member 4 is provided with a mounting portion 41, and the mounting portion 41 is configured to be connected to the dark box 6 through a threaded connector 45, and the bottom shell 3 is provided with a support portion 33 at a position corresponding to the mounting portion 41, and the support portion 33 is supported on a second surface of the mounting portion 41, and the second surface is configured as a side of the mounting portion 41 away from the panel assembly 1. In this embodiment, the panel assembly 1 includes the above-mentioned panel housing 11, screen 14, middle shell 19, control circuit board 13 and first sensor 12. The threaded connector 45 can be understood as a connector with threads, and in a preferred embodiment, the threaded connector 45 is a long bolt 451. The mounting portion 41 is provided with a through hole, so that the threaded connector 45 can pass through the mounting portion 41 and be connected to the dark box 6.

[0071] like Fig.14As shown, the dark box 6 is constructed as a box structure with one end open, and the switch device 100 is placed in the dark box 6 from the open end of the dark box 6. The left and right sides of the dark box 6 are respectively provided with connecting ears 61 inwardly, and the connecting ears 61 are provided with threaded holes. The threaded connector 45 passes through the mounting portion 41 and is connected to the threaded holes, thereby fixing the mounting member 4 to the dark box 6. When the locking force of the threaded connector 45 is large, the mounting portion 41 will deform toward the connecting ear 61, thereby causing the entire mounting member 4 to deform. In this embodiment, the bottom shell 3 of the switch device 100 is provided with a supporting portion 33 at the position where the mounting portion 41 is located, and the supporting portion 33 is supported on the second surface of the mounting portion 41, and the second surface is the side of the mounting portion 41 facing the connecting ear 61. When the locking force of the threaded connection 45 is relatively large, the support portion 33 abuts against the second surface of the mounting portion 41. At this time, the bottom shell 3 and the mounting portion 4 jointly resist the deformation of the mounting portion 41, thereby improving the anti-deformation ability of the mounting portion 41 and reducing the deformation of the mounting portion 4 and the bottom shell 3, thereby avoiding failure of the connection between the power circuit board 31 and the control circuit board 13.

[0072] like Fig.12 and Fig.13 As shown, the support portion 33 may be a buckle, a support rib or other structures. In a specific embodiment, the support portion 33 is configured as a support buckle, and the support buckle is integrally formed with the bottom shell 3. It is worth mentioning that the support portion 33 uses a support buckle so that the mounting member 4 can be sleeved on the bottom shell 3 from the bottom of the bottom shell 3. In a specific embodiment, as Fig.12 and Fig.13 As shown, the bottom shell 3 is circumferentially arranged with a plurality of abutting portions 34 and a plurality of limiting buckles 35, the mounting member 4 is sleeved on the bottom shell 3 from bottom to top, the abutting portion 34 abuts against the upper side of the mounting member 4, and the limiting buckle 35 is clamped on the lower side of the mounting member 4, so as to limit the mounting member 4. In a specific embodiment, the abutting portion 34 and the limiting buckle 35 are integrally formed on the bottom shell 3, the abutting portion 34 is constructed as a rib protruding outward from the side of the bottom shell 3, the mounting member 4 is provided with an abutting interface 42 at a position corresponding to the abutting portion 34, the abutting portion 34 is embedded in the abutting interface 42, so that the upper surface of the mounting member 4 is flush with or higher than the upper surface of the bottom shell 3, so that the mounting member can be magnetically connected to the panel assembly 1.

[0073] In some embodiments, Figure 12-14As shown, the mounting parts 41 are respectively provided on both sides of the mounting member 4, and the mounting parts 41 are provided with mounting holes 411, and the threaded connector 45 is connected to the outside through the mounting holes 411; the mounting member 4 has a first surface facing the panel assembly 1, and the mounting part 41 is recessed in the first surface, and the recess amount is less than 3mm. The purpose of the mounting part 41 being recessed in the first surface is to accommodate the nut of the threaded connector 45, so that the space of the panel assembly 1 occupied by the nut is smaller, thereby reducing the thickness of the panel assembly 1. It is worth noting that in this embodiment, the recess amount of the mounting part 41 is controlled to be less than 3mm to avoid interference between the mounting part 41 and the connecting ear 61 of the dark box 6.

[0074] It is worth noting that the mounting member 4 and the bottom shell 3 are formed separately, which is conducive to the mounting member 4 and the bottom shell 3 being made of different materials. In some embodiments, the mounting member 4 is made of iron material, and the panel assembly 1 includes a permanent magnet 18. The panel assembly 1 is magnetically connected to the mounting member 4 through the permanent magnet 18 to achieve rapid disassembly and assembly between the panel assembly 1 and the bottom shell 3.

[0075] Furthermore, the mounting member 4 is formed by stamping an iron sheet metal part, and the mounting portion 41 is integrally formed on the mounting member 4 .

[0076] Furthermore, if Figure 3 As shown, there are multiple permanent magnets 18, all of which are arranged at the first end of the panel assembly 1. The panel assembly 1 has a second end away from the first end, and the second end is provided with a snap-in position 1191. One end of the mounting member 4 is snap-into the snap-in position 1191, and the other end is magnetically connected to the permanent magnet 18. In a specific embodiment, the mounting member 4 is provided with a plug tongue 43 adapted to the snap-in position 1191 at a position corresponding to the snap-in position 1191, and the plug tongue 43 is tilted toward the panel assembly 1, and the plug tongue 43 is inserted into the snap-in position 1191 to achieve snap-in connection between the plug tongue 43 and the snap-in position 1191. The mounting member 4 is provided with a suction portion 44 at a position corresponding to the permanent magnet 18, and the suction portion 44 is integrally formed with the mounting member 4. When the panel assembly 1 is installed on the mounting member 4, firstly, the second end is brought close to the plug tongue 43 so that the plug tongue 43 is inserted into the snap-fit ​​position 1191, and then the first end is brought close to the suction portion 44 so that the suction portion 44 is sucked into the permanent magnet 18, and the installation is completed; when the panel assembly 1 is disassembled from the mounting member 4, firstly, the first end of the panel assembly 1 is opened outward so that the suction portion 44 is disengaged from the permanent magnet 18, and then the second end is moved until the plug tongue 43 is disengaged from the snap-fit ​​position 1191, and the disassembly is completed. Compared with the traditional snap-fit ​​connection, the panel assembly 1 of this embodiment adopts a connection method in which one end is snapped and the other end is magnetically attracted, so that the panel assembly 1 and the bottom shell 3 can be installed and disassembled more quickly and conveniently.

[0077] Furthermore, if Figure 5 and Figure 4 As shown, a magnet limiting groove 1192 is downwardly provided on the top wall of the panel shell 11, and the size of the magnet limiting groove 1192 is adapted to the permanent magnet 18. The magnet limiting groove 1192 is open downward, and the permanent magnet 18 is loaded from the bottom of the magnet limiting groove 1192; two limiting ribs 1193 are provided on the side of the magnet limiting groove 1192 facing the bottom shell 3, and the limiting ribs 1193 abut against the side of the permanent magnet 18 facing the bottom shell 3, and can block the permanent magnet 18 from moving toward the bottom shell 3; the middle shell 19 is provided with a magnet accommodating groove 195 at a position corresponding to the magnet limiting groove 1192, and when the middle shell 19 is buckled into the panel shell 11, the magnet accommodating groove 195 encompasses the magnet limiting groove 1192, and the magnet accommodating groove 195 abuts against the lower surface of the permanent magnet 18, and the permanent magnet 18 is limited in the magnet limiting groove 1192. The two limiting ribs 1193 are respectively located on the left and right sides of the permanent magnet 18 . When the permanent magnet 18 is attracted to the attracting portion 44 of the mounting member 4 , the attracting portion 44 is located between the two limiting ribs 1193 .

[0078] Furthermore, if Fig.13 and Fig.15 As shown, an isolation plate 5 is provided between the power circuit board 31 and the control circuit board 13, the isolation plate 5 is fixedly connected to the bottom shell 3, and the side of the isolation plate 5 abuts against the inner wall of the bottom shell 3, and the power circuit board 31 is clamped between the isolation plate 5 and the bottom shell 3. Among them, since the isolation plate 5 is fixedly connected to the bottom shell 3, and the side of the isolation plate 5 abuts against the inner wall of the bottom shell 3, the isolation plate 5 has a reinforcing effect on the rigidity of the bottom shell 3, so that the bottom shell 3 is not easy to deform, and the position of the power circuit board 31 inside the bottom shell 3 is prevented from changing greatly; and since the power circuit board 31 is clamped between the isolation plate 5 and the bottom shell 3, the position of the power circuit board 31 is more stable.

[0079] In a specific embodiment, if Fig.15 As shown, the bottom shell 3 is constructed as a box structure with an open top, the isolation plate 5 is covered on the open side of the bottom shell 3, and three connecting columns 36 are extended upward from the bottom shell 3. The isolation plate 5 is fixedly connected to the connecting columns 36 by self-tapping screws 51. The power circuit board 31 is provided with through holes at positions corresponding to the self-tapping screws 51, and the self-tapping screws 51 are connected to the connecting columns 36 through the through holes. A female header 311 is provided on one side of the power circuit board 31 facing the panel assembly 1, and a female header through hole 52 is provided on the isolation plate 5 at positions corresponding to the female header 311, and the female header 311 is exposed to the upper surface of the isolation plate 5 through the female header through hole 52.

[0080] Common air conditioners used in home decoration now include fluorine air conditioners and fan coil central air conditioners. In some embodiments, the switch device 100 can control the operation of the fan coil central air conditioner. The fan coil central air conditioner generally includes an air conditioner host, a water pump, an air conditioner water valve, a water flow pipeline and a fan coil. The air conditioner host is used to heat or cool water, and the water pump is used to drive the water to circulate, so that the heated or cooled water flows through the water flow pipeline, the air conditioner water valve, the fan coil, and finally flows back to the air conditioner host. The air conditioner water valve is used to control the water flow in the fan coil. The fan coil blows the heat or cold carried in the water into the room, so that the indoor temperature increases or decreases. The switch device 100 provided by the utility model can be connected to a fan coil central air conditioner. The switch device 100 controls the switch of the air conditioner water valve and the air volume of the fan coil to achieve the purpose of controlling the room temperature. In a specific embodiment, such as Fig.16 This is a perspective after the power circuit board 31 is flipped upside down. The bottom of the power circuit board 31 is provided with a wiring terminal 312, three single-pole single-throw relays 313 and a single-pole double-throw relay 314. The wiring terminal 312 has seven wiring holes, wherein the first wiring hole and the second wiring hole are respectively connected to the neutral wire and the live wire; the third wiring hole is connected to the high wind speed gear port of the fan coil unit, the fourth wiring hole is connected to the medium wind speed gear port of the fan coil unit, and the fifth wiring hole is connected to the low wind speed gear port of the fan coil unit. The three single-pole single-throw relays 313 are respectively electrically connected to the third wiring hole, the fourth wiring hole and the fifth wiring hole, and are used to control the fan coil unit to switch between high, medium and low gears; the sixth wiring hole is connected to the closing port of the air-conditioning water valve, and the seventh wiring hole is connected to the opening port of the air-conditioning water valve. The single-pole double-throw relay 314 is electrically connected to the sixth wiring hole and the seventh wiring hole, and is used to control the opening and closing of the air-conditioning water valve.

[0081] It is worth noting that the switch device 100 provided in this embodiment can only control the switch of the air conditioning water valve and the air volume of the fan coil. When the air conditioner needs to switch the cooling / heating mode, the user needs to operate the air conditioner host to switch. Since the switch device 100 of this embodiment only includes one single-pole double-throw relay 314, it can only control one air conditioning water valve, so this embodiment is suitable for a two-pipe fan coil central air conditioner; in other embodiments, if two single-pole double-throw relays 314 are provided on the power circuit board 31, the switch device 100 can control two air conditioning water valves, which can be suitable for a four-pipe fan coil central air conditioner.

[0082] In some embodiments, the switch device 100 can control the operation of floor heating and fresh air blower. In a specific embodiment, Fig.16As shown, a wiring terminal 312, three single-pole single-throw relays 313 and a single-pole double-throw relay 314 are provided at the bottom of the power supply circuit board 31, and the wiring terminal 312 has seven wiring holes, wherein the first wiring hole and the second wiring hole are respectively connected to the neutral wire and the live wire; the third wiring hole is connected to the high wind speed gear port of the fresh air fan, the fourth wiring hole is connected to the medium wind speed gear port of the fresh air fan, and the fifth wiring hole is connected to the low wind speed gear port of the fresh air fan, and the three single-pole single-throw relays 313 are respectively electrically connected to the third wiring hole, the fourth wiring hole and the fifth wiring hole, for controlling the fresh air fan to switch between high, medium and low gears; the sixth wiring hole is connected to the closing port of the floor heating water valve, and the seventh wiring hole is connected to the opening port of the floor heating water valve, and the single-pole double-throw relay 314 is electrically connected to the sixth wiring hole and the seventh wiring hole, for controlling the opening and closing of the floor heating water valve.

[0083] Existing fluorine air conditioners are provided with a control port, which is connected to a central controller. The central controller issues control commands to control the operation of the fluorine air conditioner. Since different brands of fluorine air conditioners have different communication protocols, existing thermostats are difficult to adapt to multiple brands of fluorine air conditioners. In addition, control commands are transmitted via weak current, and existing thermostats generally set the weak current board in the panel housing and the strong current board in the bottom housing. Since the thermostat needs to be wired inside the dark box, the weak current board cannot be directly connected to the communication wire, which brings inconvenience to the wiring. In order to enable the switch device 100 provided by the utility model to control fluorine air conditioners of various brands and facilitate the connection of communication wires, in some embodiments, such as Fig.16 As shown, the power circuit board 31 and the communication circuit board 315 are arranged inside the bottom shell 3, and the communication circuit board 315 is electrically connected to the power circuit board 31, the power circuit board 31 carries a strong current circuit, and the communication circuit board 315 carries a weak current circuit; the communication circuit board 315 can switch the communication protocol and is configured to output a control signal to the outside. Among them, the switching communication protocol can be understood as the user can set an adaptive communication protocol according to the brand of the controlled device, so that the control signal output by the communication circuit board 315 can control the operation of the controlled device. The communication circuit board 315 can output the control signal to the outside in a wired manner or a wireless manner. A power module is arranged on the power circuit board 31, which can convert strong electricity into weak electricity, thereby providing power for the communication circuit board 315.

[0084] The switch device 100 provided by the utility model switches the communication protocol by the communication circuit board 315, so that the control signal output by the switch device 100 can control controlled devices of different brands, and thanks to the fact that the communication circuit board 315 is arranged on the power circuit board 31, the communication circuit board 315 is located in the bottom shell 3, so that the communication wires of the controlled devices can be more directly and conveniently connected to the communication circuit board 315. It can be understood that if the communication circuit board 315 is arranged on the control circuit board 13, the communication circuit board 315 will not only occupy the space of the panel assembly 1, but also be inconvenient to connect the communication wires.

[0085] Furthermore, if Fig.16 As shown, the communication circuit board 315 is welded to the power circuit board 31; the power circuit board 31 is provided with a communication terminal 316, the communication terminal 316 is used to connect to the controlled device, the communication terminal 316 is electrically connected to the communication circuit board 315 via the power circuit board 31, so that the communication circuit board 315 will not be loosened due to wiring with the power circuit board 31, and the communication circuit board 315 outputs a control signal to the outside through the communication terminal 316. The controlled device includes a fluorine machine air conditioner and a fresh air fan, and the communication circuit board 315 can simultaneously control the operation of the fluorine machine air conditioner and the fresh air fan. Further, the communication circuit board 315 and the communication terminal 316 are both arranged on the lower surface of the power circuit board 31, and the communication terminal 316 is provided with a plurality of connection holes for connecting the communication wires of the controlled device, and the bottom shell 3 is provided with a wiring through hole at the corresponding position of each connection hole, and the communication wire passes through the wiring through hole and is connected to the connection hole. Further, the communication terminal 316 and the connection terminal 312 are respectively arranged at both ends of the power circuit board 31. The communication terminal 316 is arranged at a corner of the power circuit board 31 , and the bottom shell 3 is provided with three connecting posts 36 , which are respectively located at the corners of the power circuit board 31 . The bottom shell 3 does not have the connecting post 36 near the communication terminal 316 .

[0086] Furthermore, if Fig.16 As shown, the communication circuit board 315 is vertically soldered to the power circuit board 31 to facilitate heat dissipation of the communication circuit board 315 .

[0087] Furthermore, if Fig.16As shown, the communication circuit board 315 is provided with a second communication module, and the second communication module can communicate wirelessly with the outside. The communication circuit board 315 switches the communication protocol based on the signal input of the second communication module, so that the communication circuit board 315 can independently connect to the terminal in a wireless communication manner, and the user can wirelessly control the communication circuit board 315 to switch the communication protocol through the terminal, thereby improving the convenience of operation. In one embodiment, the second communication module is a Bluetooth communication module, and the user can select the brand and model of the controlled device through the mobile phone APP, and transmit the controlled device information to the second communication module through Bluetooth communication. The communication circuit board 315 switches the communication protocol to a communication protocol compatible with the controlled device model based on the controlled device information received by the second communication module. Furthermore, the communication circuit board 315 is provided with an onboard antenna 317, and the onboard antenna 317 is electrically connected to the second communication module.

[0088] In the installation process of existing wall switches, in order to prevent the bottom shell from being damaged due to excessive locking force of long bolts, a metal mounting piece is often set around the bottom shell, and the mounting piece is fixedly connected to the bottom shell. During installation, the long bolts lock the mounting piece to the dark box, and the bottom shell is indirectly fixed to the dark box through the mounting piece, thereby preventing the bottom shell from being damaged. However, since the mounting piece is generally made of sheet metal, it has low rigidity and is easily deformed under the action of the locking force of the long bolts. The bottom shell will deform along with the mounting piece, causing the position of the power circuit board inside the bottom shell to change. Since the power circuit board and the control circuit board are generally connected by pin and female headers or spring conductive pins, changes in the position of the power circuit board will cause a connection failure between the power circuit board and the control circuit board.

[0089] In order to improve the problem that the mounting member and the bottom shell are easily deformed, according to the second aspect of the utility model, as Figure 1-Figure 16 As shown, a switch device 100 is provided, which is suitable for being installed on a wall. Figure 3 and Figure 12-14 The switch device 100 includes a panel assembly 1, a bottom shell 3 and a mounting member 4 arranged around the bottom shell 3, wherein the mounting member 4 is formed separately from the bottom shell 3; wherein the mounting member 4 is provided with a mounting portion 41, wherein the mounting portion 41 is configured to be connectable to the junction box 6 via a threaded connector 45, and the bottom shell 3 is provided with a supporting portion 33 at a position corresponding to the mounting portion 41, wherein the supporting portion 33 is supported on a second surface of the mounting portion 41, and the second surface is configured as a side of the mounting portion 41 facing away from the panel assembly 1. The technical details of the panel assembly 1, the bottom shell 3, the mounting member 4 and the supporting portion 33 are described in detail above and will not be repeated here. Fig.14As shown, the threaded connector 45 passes through the mounting portion 41 and is connected to the threaded hole, thereby fixing the mounting member 4 to the dark box 6. When the locking force of the threaded connector 45 is large, the mounting portion 41 will deform toward the connecting ear 61, thereby driving the entire mounting member 4 to deform. In this embodiment, the bottom shell 3 of the switch device 100 is provided with a support portion 33 at the location of the mounting portion 41, and the support portion 33 is supported on the second surface of the mounting portion 41, and the second surface is the side of the mounting portion 41 facing the connecting ear 61. When the locking force of the threaded connector 45 is large, the support portion 33 abuts against the second surface of the mounting portion 41, which is equivalent to the bottom shell 3 and the mounting member 4 jointly resisting the deformation of the mounting portion 41, thereby improving the anti-deformation ability of the mounting portion 41, reducing the deformation of the mounting member 4 and the bottom shell 3, and thus avoiding the connection failure between the power circuit board 31 and the control circuit board 13.

[0090] like Fig.12 and Fig.13 As shown, the support portion 33 may be a buckle, a support rib or other structures. In a specific embodiment, the support portion 33 is configured as a support buckle, and the support buckle is integrally formed with the bottom shell 3. It is worth mentioning that the support portion 33 uses a support buckle so that the mounting member 4 can be sleeved on the bottom shell 3 from the bottom of the bottom shell 3. In a specific embodiment, as Fig.12 and Fig.13 As shown, the bottom shell 3 is circumferentially arranged with a plurality of abutting portions 34 and a plurality of limiting buckles 35, the mounting member 4 is sleeved on the bottom shell 3 from bottom to top, the abutting portion 34 abuts against the upper side of the mounting member 4, and the limiting buckle 35 is clamped on the lower side of the mounting member 4, so as to limit the mounting member 4. In a specific embodiment, two limiting buckles 35 are respectively arranged on the two opposite sides of the bottom shell 3, and the abutting portion 34 and the limiting buckle 35 are integrally formed on the bottom shell 3. The abutting portion 34 is constructed as a rib protruding outward from the side of the bottom shell 3, and the mounting member 4 is provided with an abutting interface 42 at a position corresponding to the abutting portion 34, and the abutting portion 34 is embedded in the abutting interface 42, so that the upper surface of the mounting member 4 is flush with or higher than the upper surface of the bottom shell 3, so that the mounting member can be magnetically connected to the panel assembly 1.

[0091] In some embodiments, Figure 12-14As shown, the mounting parts 41 are respectively provided on both sides of the mounting member 4, and the mounting parts 41 are provided with mounting holes 411, and the threaded connector 45 is connected to the outside through the mounting holes 411; the mounting member 4 has a first surface facing the panel assembly 1, and the mounting part 41 is recessed in the first surface, and the recess amount is less than 3mm. The purpose of the mounting part 41 being recessed in the first surface is to accommodate the nut of the threaded connector 45, so that the space of the panel assembly 1 occupied by the nut is smaller, thereby reducing the thickness of the panel assembly 1. It is worth noting that in this embodiment, the recess amount of the mounting part 41 is controlled to be less than 3mm to avoid interference between the mounting part 41 and the connecting ear 61 of the dark box 6.

[0092] It is worth noting that the mounting member 4 and the bottom shell 3 are formed separately, which is conducive to the mounting member 4 and the bottom shell 3 being made of different materials. In some embodiments, the mounting member 4 is made of iron material, and the panel assembly 1 includes a permanent magnet 18. The panel assembly 1 is magnetically connected to the mounting member 4 through the permanent magnet 18 to achieve rapid disassembly and assembly between the panel assembly 1 and the bottom shell 3.

[0093] Furthermore, the mounting member 4 is formed by stamping an iron sheet metal part, and the mounting portion 41 is integrally formed on the mounting member 4 .

[0094] Furthermore, if Figure 3 As shown, there are multiple permanent magnets 18, all of which are arranged at the first end of the panel assembly 1. The panel assembly 1 has a second end away from the first end, and the second end is provided with a snap-in position 1191. One end of the mounting member 4 is snap-into the snap-in position 1191, and the other end is magnetically connected to the permanent magnet 18. Among them, the attraction and disassembly process of the panel assembly 1 and the mounting member 4 are described in detail above and will not be repeated here. Compared with the traditional snap-on connection, the panel assembly 1 of this embodiment adopts a connection method in which one end is snap-in and the other end is magnetically attracted, so that the panel assembly 1 and the bottom shell 3 can be installed and disassembled more quickly and conveniently.

[0095] Furthermore, if Fig.13 and Fig.15As shown, the panel assembly 1 includes a control circuit board 13, and the bottom shell 3 is provided with a power circuit board 31. The control circuit board 13 is connected to the power circuit board 31 through a pin header 131 and a female header 311; an isolation plate 5 is provided between the power circuit board 31 and the control circuit board 13, and the isolation plate 5 is fixedly connected to the bottom shell 3, and the side of the isolation plate 5 abuts against the inner wall of the bottom shell 3, and the power circuit board 31 is clamped between the isolation plate 5 and the bottom shell 3. Among them, since the isolation plate 5 is fixedly connected to the bottom shell 3, and the side of the isolation plate 5 abuts against the inner wall of the bottom shell 3, the isolation plate 5 has a reinforcing effect on the rigidity of the bottom shell 3, so that the bottom shell 3 is not easy to deform, and the position of the power circuit board 31 inside the bottom shell 3 is prevented from changing greatly; and since the power circuit board 31 is clamped between the isolation plate 5 and the bottom shell 3, the position of the power circuit board 31 is more stable. The technical details of the bottom shell 3 and the isolation plate 5 are described in detail above, and will not be repeated here.

[0096] Existing fluorine air conditioners are provided with a control port, which is connected to a central controller. The central controller issues control commands to control the operation of the fluorine air conditioner. Since different brands of fluorine air conditioners have different communication protocols, existing thermostats are difficult to adapt to multiple brands of fluorine air conditioners. In addition, control commands are transmitted via weak current, and existing thermostats generally set the weak current board in the panel housing and the strong current board in the bottom housing. Since the thermostat needs to be wired inside the dark box, the weak current board cannot be directly connected to the communication wire, which brings inconvenience to the wiring. In order to enable the switch device 100 provided by the utility model to control fluorine air conditioners of various brands and facilitate the connection of communication wires, in some embodiments, such as Fig.16 As shown, the power circuit board 31 and the communication circuit board 315 are arranged inside the bottom shell 3, and the communication circuit board 315 is electrically connected to the power circuit board 31, the power circuit board 31 carries a strong current circuit, and the communication circuit board 315 carries a weak current circuit; the communication circuit board 315 can switch the communication protocol and is configured to output a control signal to the outside. Among them, the switching communication protocol can be understood as the user can set an adaptive communication protocol according to the brand of the controlled device, so that the control signal output by the communication circuit board 315 can control the operation of the controlled device. The communication circuit board 315 can output the control signal to the outside in a wired manner or a wireless manner. A power module is arranged on the power circuit board 31, which can convert strong electricity into weak electricity, thereby providing power for the communication circuit board 315.

[0097] The switch device 100 provided by the utility model switches the communication protocol by the communication circuit board 315, so that the control signal output by the switch device 100 can control controlled devices of different brands, and thanks to the fact that the communication circuit board 315 is arranged on the power circuit board 31, the communication circuit board 315 is located in the bottom shell 3, so that the communication wires of the controlled devices can be more directly and conveniently connected to the communication circuit board 315. It can be understood that if the communication circuit board 315 is arranged on the control circuit board 13, the communication circuit board 315 will not only occupy the space of the panel assembly 1, but also be inconvenient to connect the communication wires.

[0098] Furthermore, if Fig.16 As shown, the communication circuit board 315 is welded to the power circuit board 31; the power circuit board 31 is provided with a communication terminal 316, and the communication terminal 316 is used to connect to the controlled device. The communication terminal 316 is electrically connected to the communication circuit board 315 via the power circuit board 31, so that the communication circuit board 315 will not be loosened due to wiring with the power circuit board 31, and the communication circuit board 315 outputs control signals to the outside through the communication terminal 316. The controlled devices include fluorine machine air conditioners, fresh air blowers, etc. Further, the communication circuit board 315 and the communication terminal 316 are both arranged on the lower surface of the power circuit board 31, and the communication terminal 316 is provided with a plurality of connection holes for connecting the communication wires of the controlled device. The bottom shell 3 is provided with wiring through holes at the corresponding positions of each connection hole, and the communication wire passes through the wiring through holes and is connected to the connection holes.

[0099] Furthermore, if Fig.16 As shown, the communication circuit board 315 is vertically soldered to the power circuit board 31 to facilitate heat dissipation of the communication circuit board 315 .

[0100] Furthermore, if Fig.16 As shown, the communication circuit board 315 is provided with a second communication module, and the second communication module can communicate wirelessly with the outside. The communication circuit board 315 switches the communication protocol based on the signal input of the second communication module, so that the communication circuit board can independently connect to the terminal in a wireless communication manner. The user can wirelessly control the communication circuit board 315 to switch the communication protocol through the terminal, thereby improving the convenience of operation. In one embodiment, the second communication module is a Bluetooth communication module, and the user can select the brand and model of the controlled device through the mobile phone APP, and transmit the controlled device information to the second communication module through Bluetooth communication. The communication circuit board 315 switches the communication protocol to a communication protocol compatible with the controlled device model based on the controlled device information received by the second communication module. Furthermore, the communication circuit board 315 is provided with an onboard antenna 317, and the onboard antenna 317 is electrically connected to the second communication module.
