Description

Technical Field

[0001] This invention relates to the field of intelligent switch technology, and in particular to an intelligent switch and system. Background Technology

[0002] With the advent of the smart era, smart switches have gradually been used to replace traditional mechanical switches due to their advantages such as intelligence, diversified control, and convenient operation. More and more users are choosing smart switches to control indoor electrical appliances during home renovation. Summary of the Invention

[0003] Existing multi-channel smart switches all support the simultaneous activation of multiple control channels. For example, a three-channel smart switch can control three lights respectively through its three control channels, thus enabling all three lights to be turned on simultaneously. However, for electrical appliances with multiple speed settings, such as air purifiers and electric fans, existing smart switches lack a good solution to accommodate the selective switching between multiple speed settings of the same appliance. This hinders the application and promotion of smart switches for such appliances, requiring users to purchase dedicated controllers, increasing costs. Therefore, the present invention aims to provide a smart switch and system, wherein the smart switch has a first mode, enabling it to lock multiple operating areas into a selective trigger state, thus adapting to the application scenario of selective switching between multiple speed settings of the same electrical appliance.

[0004] Furthermore, another objective of this invention is to provide an intelligent switch and system, wherein the first mode of the processing device of the intelligent switch is an optional feature that can be freely selected by the user. When the user sets the processing device to a mode other than the first mode (e.g., the third mode), the intelligent switch has the functions of a general intelligent switch and can be applied to ordinary intelligent control scenarios (e.g., lighting control scenarios). When the user sets the processing device to the first mode, the intelligent switch is locked in a selective trigger state and can be applied to some special application scenarios (e.g., the selective switching application scenario between multiple speeds of the same electrical device such as a fresh air system). Due to the introduction of the first mode, the intelligent switch provided in this embodiment has more diversified control objects and usage scenarios, providing users with more freedom of choice.

[0005] Another objective of this invention is to provide an intelligent switch and system, wherein, unlike the third mode of the intelligent switch, in the first mode, only one of the multiple on / off devices of the intelligent switch can be turned on at the same time, and the multiple on / off devices cannot be turned on simultaneously, so that the multiple on / off devices of the intelligent switch have a selective triggering state, to adapt to the application scenario of selective switching between multiple gears of the same electrical device.

[0006] Another object of the present invention is to provide an intelligent switch and system, wherein the intelligent switch is adapted to be connected to a target circuit and used to control the target circuit through the on / off device, so that when an electrical device is connected to the target circuit, the multiple on / off devices of the intelligent switch control the on / off of multiple gear positions of the electrical device respectively; wherein in a first mode, the processing device of the intelligent switch locks the on / off device to a selective trigger state, such that at most one of the at least two on / off devices is allowed to enter the on state at the same time, so as to selectively trigger multiple gear positions of the electrical device.

[0007] Another objective of this invention is to provide an intelligent switch and system, wherein when the intelligent switch connects a new on / off device, it will first close the already connected on / off device to avoid connecting two on / off devices at the same time.

[0008] Another objective of this invention is to provide an intelligent switch and system, which, unlike the global effect of the first mode (i.e., entering the first mode is done on a unit-by-unit basis, and once the first mode is entered, the functions of all operating areas are affected), supports local switching of the operating modes of the operating areas. That is, switching is performed on a unit-by-unit basis, and the operating mode switching of each operating area can be performed independently without affecting each other, thus enriching the control methods of multi-operating-area intelligent switches. Users can set corresponding operating modes for each operating area according to specific application scenarios and controlled objects. Furthermore, each operating area can enter an on / off mode to have the on / off control function of a traditional mechanical switch, and can enter a wireless mode to extend the controlled devices, so that the controlled terminals are not limited to controlled devices directly electrically connected to the electronic switch of the intelligent switch.

[0009] Another objective of this invention is to provide an intelligent switch and system, wherein the first mode of the intelligent switch will have a higher priority, so that all operating areas in the first mode are forced to enter the on / off mode, and operating areas set to wireless mode will also be forced to switch to the on / off mode.

[0010] Another objective of this invention is to provide an intelligent switch and system, wherein when the intelligent switch is triggered to enter the first mode from a non-first mode (e.g., from the third mode to the first mode), regardless of how many electronic switches were previously in the on state, all electronic switches will be switched to the off state, so that when initially entering the first mode, the control channels of each operating area of ​​the intelligent switch are in the off state, thereby turning off the connected electrical equipment, so as to facilitate subsequent operation by the user.

[0011] Another objective of this invention is to provide a smart switch and system, wherein the smart switch has a second mode. In the second mode, the electronic switch corresponding to the operation area set to wireless mode will not be disconnected by user operation or by other communication commands other than the first mode. In some application scenarios, the smart switch is connected to a target circuit, and the target circuit is connected to at least one smart device. If the corresponding electronic switch is disconnected, the smart device will lose power and go offline, causing inconvenience to the user. This problem can be solved by entering the second mode. In the second mode, the on / off state of the electronic switch corresponding to the operation area of ​​the wireless mode is locked, thereby solving the problem of smart devices always losing power and going offline in some application scenarios and improving the limitations of the smart switch's usage scenarios. Furthermore, the user can control whether the smart switch enters the second mode through a terminal device, which also increases the user's freedom of choice.

[0012] Another objective of this invention is to provide a smart switch and system, wherein the first mode has a higher priority than the second mode. That is, when the smart switch enters the first mode, all operating areas will be forced to enter the on / off mode, and the operating areas set to wireless mode will also be forced to switch to the on / off mode, causing the second mode to fail.

[0013] Another objective of this invention is to provide an intelligent switch and system, wherein in a non-first mode, the intelligent switch still has the functions of an ordinary intelligent switch, while in the first mode, the intelligent switch is equivalent to a dedicated switch for the multi-speed device, allowing the user to freely change the functional mode of the intelligent switch according to different usage environments without having to configure a dedicated switch for the multi-speed device.

[0014] To achieve at least one of the above objectives, according to a first aspect of the present invention, a smart switch is provided, comprising:

[0015] At least two switching devices, each having an on state and an off state;

[0016] Processing device for controlling the on / off state of the switching device;

[0017] The processing device can be configured to switchably operate in a first mode and a third mode;

[0018] In the first mode, the switching device is locked in a selective trigger state, so that at most one of the at least two switching devices can be allowed to enter the on state at the same time.

[0019] In the third mode, two or more on / off devices are allowed to be in the on state simultaneously.

[0020] According to an embodiment of the present invention, in a first mode, the processing device is specifically used for:

[0021] When a control is received instructing a switching device to switch to the ON state, if another switching device is already in the ON state, the other switching device is first switched to the OFF state, and then the first switching device is switched to the ON state.

[0022] According to an embodiment of the present invention, the switching device includes:

[0023] The operating area for receiving control; and

[0025] The processing device is capable of detecting the manipulation applied to the operating area and controlling the corresponding electronic switch to be turned on and off accordingly; when the electronic switch is turned on, it forms the on state of the corresponding on / off device, and when the electronic switch is turned off, it forms the off state of the corresponding on / off device.

[0026] The processing device is also configured to: in a third mode, allow each operating area to switch operating modes independently; the operating modes include on / off mode and wireless mode;

[0027] In the on / off mode, the operation area is used to receive control to switch the on / off state of the corresponding electronic switch; in the wireless mode, the operation area is used to receive control to send a specified wireless signal, wherein the electronic switch corresponding to the operation area in the wireless mode remains on and will not be disconnected according to the control received by the operation area.

[0028] According to an embodiment of the present invention, the processing device is further configured to lock all operating areas to on / off mode in the first mode, and if there are operating areas in wireless mode before entering the first mode, entering the first mode will trigger the processing device to forcibly switch all operating areas in wireless mode to on / off mode.

[0029] According to an embodiment of the present invention, the processing device is further configured to, when entering the first mode from a non-first mode, forcibly switch all electronic switches corresponding to the operating areas to the off state.

[0030] According to an embodiment of the present invention, the processing device can be configured to have a second mode; in the second mode, the on / off state of electronic switches corresponding to all operating areas in wireless mode is locked, so that the electronic switches in the second mode will not be disconnected by other communication commands other than the first mode.

[0031] According to an embodiment of the present invention, the processing device is capable of establishing a communication connection with an external terminal device and is capable of implementing at least one of the following controls based on the operation of the terminal device:

[0032] According to a first control command originating from a terminal device that has established a communication connection, the device switches to the first mode, the second mode, or the third mode.

[0033] In the second or third mode, the working mode of each operating area is switched independently according to the second control command of the terminal device;

[0034] In the first and third modes, the on and off states of the electronic switches in the operation area of ​​the terminal device are switched according to the third control command of the terminal device. In the first mode, at most one electronic switch can still be turned on at the same time through the third control command.

[0035] The first control command, the second control command, and the third control command are all compiled according to a predetermined communication protocol and are different from each other.

[0036] According to an embodiment of the present invention, the smart switch is adapted to be connected to a target circuit and used to control the target circuit through the switching device, so that when a multi-speed device is connected to the target circuit, the multiple switching devices of the smart switch control the circuit switching of multiple speeds of the multi-speed device respectively; wherein in a first mode, the processing device of the smart switch locks the switching device to a selective triggering state, so that at most one of the at least two switching devices is allowed to enter the on state at the same time, so as to selectively trigger multiple speeds of the multi-speed device.

[0037] To achieve at least one of the above objectives, according to a second aspect of the present invention, an intelligent control system is provided, comprising an intelligent switch as described in the first aspect above, and a multi-position device;

[0038] The electronic switches corresponding to the multiple operating areas of the smart switch are respectively used to control the on / off state of each gear of the multi-gear device, so as to control the on / off state of each gear of the multi-gear device through the operating areas of the smart switch; wherein the smart switch is adapted to be configured to enter a first mode so that at most one gear of the multi-gear device is turned on at the same time.

They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0086] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0087] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" and other such terms should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0088] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by the present invention.

[0089] Currently, most button-type smart switches pre-print text or images on the buttons to indicate their functions. If the user changes the function of a button, the button itself needs to be replaced, which is inconvenient and wasteful. To solve this problem, please refer to... Figures 1-24 This invention provides a smart switch 100, which is specifically illustrated below. For example... Figures 1-5As shown, the smart switch 100 includes a panel base 1, a pressing part 2, and a display device 10. The pressing part 2 is connected to the panel base 1 and includes multiple buttons 21. The display device 10 includes multiple displays 101 corresponding to each button 21. Each display 101 is disposed on the panel base 1 and is used to display the button information of the corresponding button 21. The smart switch 100 provided by the present invention can display the information corresponding to each button 21 through the display 101. Users can change the content displayed on the display 101 to adapt to changes in button functions, solving the problem in the prior art that the pattern or text needs to be changed by replacing the button 21. The one-to-one correspondence between the display 101 and the button 21 can be understood as the number of display 101 being equal to the number of buttons 21, and their positions corresponding to the positions of the buttons 21. For example, each display 101 can be located near the end of each button 21. The advantage of using multiple independent displays 101 compared to using a single display 101 is that it improves the effective utilization rate of the display area of ​​a single display 101, reduces blank areas, and when one of the displays 101 is damaged, it can be replaced individually, saving maintenance costs.

[0090] In addition, such as Figures 1-5 As shown, in the smart switch 100 provided by the present invention, one end of each of the buttons 21 is connected to form the connection end 22 of the pressing part 2, and the other end of each button 21 away from the first end is separated to form the pressing end 23 of the pressing part 2. This is so that when one of the buttons 21 is pressed, the other buttons 21 will not move accordingly, and each button 21 provides a reset force to each other through the connection end 22. Each display screen 101 is disposed close to the connection end 22. The connection of one end of each button 21 can be integrally formed, fixedly connected by a fixing piece, or other forms of connection. The mutual reset force provided by each button 21 can be understood as follows: the ends of each button 21 are connected through the connection end 22. When one button 21 is pressed, the button 21 causes the connection end 22 to move, while the connection end 22 remains stationary due to the connection of the other buttons 21. This causes deformation of the connection end 22 and the pressed button 21, thereby generating a reset force. The fact that the display screen 101 is located near the connection end 22 can be understood as each display screen 101 being located near the end of each button 21 in a corresponding manner.

[0091] The intelligent switch 100 provided by the present invention has its ends of each button 21 connected to each other, so that the spacing between each button 21 is consistent, and the positional correspondence between the button 21 and the display screen 101 is more accurate. At the same time, since the ends of each button 21 are connected, each button 21 can provide a reset force to each other, eliminating the need for an additional reset structure and simplifying the structure. Furthermore, the connection of each button 21 prevents the button 21 from shaking or becoming loose, improving the pressing feel.

[0092] According to embodiments of the present invention, such as Figure 9 and Figure 13 As shown, the smart switch 100 also includes a bottom shell 3, which has a mounting hole 31 for external installation. The pressing part 2 covers the mounting hole 31. When installing the smart switch 100, the user only needs to remove the pressing part 2 to expose the mounting hole 31, and then pass the mounting screw 32 through the mounting hole 31 to connect it to the wall junction box, thereby fixing the smart switch 100 to the wall. The installation process does not require removing the panel base 1, which protects the internal circuit board 5 and avoids the risk of the circuit board 5 falling and breaking after being removed along with the panel base 1.

[0093] Since the smart switch 100 provided by this invention requires the button 21 to be disassembled before it can be installed externally, the button 21 needs to be easy to disassemble and assemble. Furthermore, each button 21 should not be disassembled individually during disassembly and assembly to avoid breaking the connecting ends 22 of each button 21. Based on this, this embodiment of the invention provides a series of buttons 21 that are easy to disassemble and assemble, including a plug-in structure 241, an abutment structure 242, and a movable snap-fit ​​structure 243. These three structures cooperate with each other to achieve the effect of easy disassembly and assembly of the button 21. Figure 6 , Figure 3 and Figure 9 As shown, the connecting end 22 of the pressing part 2 is provided with the insertion structure 241, and the panel base 1 is provided with the insertion position 11. The insertion structure 241 is inserted into the insertion position 11 and is restricted by the insertion position 11 to move in the fifth direction. The fifth direction is opposite to the direction in which the button 21 is pressed. Figure 5 This is a top view of the smart switch 100. Figure 6 for Figure 5 In the AA-step sectional view, it should be noted that the insertion structure 241, the abutment structure 242, and the movable snap-fit ​​structure 243 are not on the same vertical plane (by...). Figure 3 It can be seen that... Figure 6 By using a stepped sectioning method to concentrate the three elements onto the same cross-section, the structure can be displayed more intuitively. The fifth direction is... Figure 6 The fifth direction is already in the vertical upward direction. Figure 6The selected structure is the plug-in structure 241, which can be a tongue, pin, plate, or other plug-in structure. The insertion direction of the plug-in structure 241 can be... Figure 6 The horizontal direction can be an upward or downward tilting direction. The plug-in position 11 can abut against the upper surface of the plug-in structure 241 during the movement of the button 21 to restrict the movement of the plug-in structure 241 toward the fifth direction.

[0094] The connecting end 22 of the pressing part 2 is provided with the abutting structure 242 facing the second direction. The abutting structure 242 is disposed between the insertion structure 241 and the pressing end 23. The second direction is the same as the direction in which the button 21 is pressed. Figure 6 The vertical downward direction is already in the second direction. Figure 6 The panel base 1 has a supporting and limiting structure 12 at the corresponding position of the abutting structure 242. The abutting structure 242 abuts against the supporting and limiting structure 12. The supporting and limiting structure 12 can restrict the insertion structure 241 from disengaging from the insertion position 11. When the abutting structure 242 abuts against the supporting and limiting structure 12, the two cooperate to restrict the button 21 from moving horizontally, thereby restricting the insertion structure 241 from disengaging from the insertion position 11 to the right. Figure 7 The diagram shows a schematic of the pressing end 23 of the pressing part 2 under pressure. When the pressing end 23 is pressed, it moves around the support limiting structure 12. For example, the button 21 can pivot around the support limiting structure 12, thereby driving the pressing end 23 to move; or the button 21 can deform around the support limiting structure 12, and the deformation of the button 21 can drive the pressing end 23 to move downward, thereby triggering the detection element 52. Each button 21 has a movable latching structure 243 near the pressing end 23 facing the second direction. The movable latching structure 243 is latched onto the panel base 1, which can restrict the pressing end 23 of the button 21 from detaching from the panel base 1 in the fifth direction, and the movable latching structure 243 can move in the second direction.

[0095] like Figure 8 As shown, Figure 8 for Figure 6The diagram illustrates the disassembly process of the pressing part 2. When the pressing part 2 is disassembled from the panel base 1, the user can first pry the pressing end 23 upwards, causing each of the movable locking structures 243 to disengage from the panel base 1. The pressing part 2 can then rotate counterclockwise based on the insertion structure 241. When the rotation angle reaches a certain value, the abutting structure 242 disengages from the supporting limiting structure 12, thereby freeing the pressing part 2 from the restriction of the supporting limiting structure 12, allowing the insertion structure 241 to disengage from the insertion position 11 to the right. The entire disassembly process is simple and quick, suitable for the feature of the smart switch 100 requiring the pressing part 2 to be disassembled before external installation. Moreover, compared to the prior art where each button 21 is provided with a hole for rotational connection with the panel base 1, this embodiment adopts a scheme in which the plug-in structure 241 and the abutment structure 242 cooperate, so that the pressing part 2 can be completely disassembled from the panel base 1 without disassembling each button 21 one by one, thus avoiding the connection end 22 connecting each button 21 from being broken. Therefore, the disassembly scheme of the pressing part 2 provided in this embodiment is more suitable for the row of buttons 21 structure of the present invention.

[0096] Correspondingly, the installation process of the pressing part 2 is the reverse of the disassembly process, such as... Figure 8 As shown, when the pressing part 2 is installed on the panel base 1, the plug-in structure 241 can be inserted into the plug-in position 11 at an angle to the lower left. Then, the pressing part 2 is rotated clockwise based on the plug-in structure 241, so that the abutting structure 242 abuts against the supporting limiting structure 12. Finally, the pressing end 23 is pressed down, so that the movable locking structure 243 is locked onto the panel base 1, completing the installation. The entire installation process is quick and convenient, which is suitable for the characteristic that the smart switch 100 of the present invention needs to install the pressing part 2 on the panel base 1 after being installed on the wall.

[0097] Furthermore, such as Figure 8 As shown, during the installation and removal of the pressing part 2, when the pressing part 2 is tilted, the left end of the pressing part 2 abuts against the transparent cover plate 4. To ensure that the pressing part 2 can be installed and removed smoothly, as follows... Figure 6 As shown, there is a certain gap between the left end of the pressing part 2 and the transparent cover plate 4. This gap is reserved for the pressing part 2 to rotate, so that when the pressing part 2 is tilted during the installation and disassembly of the pressing part 2, the transparent cover plate 4 will not interfere with the pressing part 2.

[0098] According to embodiments of the present invention, such as Figure 7 and Figure 6As shown, the insertion position 11 abuts against the side of the insertion structure 241 facing the fifth direction. When the pressing end 23 is pressed, the pressing end 23 moves with the support limiting structure 12 as the fulcrum. The insertion position 11 provides the insertion structure 241 with an abutting force facing the second direction, causing the pressing end 23 to generate a restoring force. The pressing part 2 is equivalent to a seesaw structure with the support limiting structure 12 as the fulcrum. The insertion position 11 restricts the left end of the pressing part 2 from moving upwards through the insertion structure 241. When the pressing end 23 located at the right end of the pressing part 2 is pressed, the pressing end 23 moves downwards. Because the left end of the pressing part 2 is restricted from moving upwards, the pressed button 21 bends and deforms, while the other unpressed buttons 21 remain in their initial state. The deformation of the buttons 21 generates a restoring force, which is set as the first restoring force. Secondly, since the buttons 21 are interconnected via the connecting end 22, they can also provide a reset force to each other, which is designated as the second reset force. In addition, the button 21 presses against the detection element 52, causing the detection element 52 to generate a reaction force on the button 21, which is designated as the third reset force. When the pressing force is removed, the pressed button 21 resets under the combined action of the first, second, and third reset forces, eliminating the need for an additional reset structure and simplifying the structure.

[0099] Furthermore, the detection element 52 is selected from one of a tactile switch, a micro switch, a detection switch, a membrane switch, and a Hall switch. In a preferred embodiment, the detection element 52 is selected from a tactile switch.

[0100] Furthermore, such as Figure 6 As shown, the detection element 52 is provided on the side of the circuit board 5 facing the panel substrate 1. A trigger post 211 is provided on the button 21 facing the detection element 52. The button 21 triggers the detection element 52 through the trigger post 211. When the button 21 is not pressed, the detection element 52 is still pressed against the trigger post 211, generating a small amount of compression. This compression is insufficient to trigger the detection element 52, but it provides preload to the button 21, preventing it from feeling loose and providing a firmer pressing feel. Furthermore, this compression ensures that the trigger post 211 and the detection element 52 remain in contact, eliminating the gap between them and thus eliminating the button 21's free travel and improving its trigger sensitivity. Further, as... Figure 3 , Figure 6 and Figure 9 As shown, the plug-in structure 241 includes a tongue disposed from the connecting end 22 toward a third direction. The tongue is inserted into the plug-in position 11 and is restricted by the plug-in position 11 from moving toward the fifth direction. The third direction is the direction from the pressing end 23 of the pressing part 2 toward the connecting end 22. Figure 6 The middle horizontal direction to the left, the third direction is already Figure 6 and Figure 3 The key is marked. In a specific embodiment, the connecting end 22 of the pressing part 2 extends into an extension wall 2411 in the second direction, and the bottom end of the extension wall 2411 protrudes into the third direction with the tongue; the number of the tongues is set to two, and the two tongues are arranged at intervals along the first direction, which is set as the arrangement direction of the button 21. The first direction has already been marked. Figure 3 The selected element is shown in the diagram. The number of abutting structures 242 is set to two, with the two abutting structures 242 arranged at intervals along a first direction, and located between two insertion structures 241 in the first direction. Additionally, each button 21 is provided with one movable latching structure 243 and one trigger post 211, with each movable latching structure 243 and each trigger post 211 arranged along the first direction. It is worth noting that, in the third direction, the movable latching structure 243, trigger post 211, abutting structure 242, and insertion structure 241 are arranged sequentially. Further, as shown in the diagram... Figure 9 As shown, the insertion position 11 includes a horizontally arranged limiting rib, which abuts against the upper surface of the tongue to restrict the upward movement of the tongue.

[0101] Furthermore, such as Figure 6 and Figure 3 As shown, the support limiting structure 12 is constructed as a first rotating shaft 121. The abutment structure 242 is provided with a flared abutment recess 2421 facing the first rotating shaft 121. The abutment recess 2421 abuts against the first rotating shaft 121 to restrict the pressing part 2 from translating in the opposite direction to the third direction, thereby restricting the insertion structure 241 from disengaging from the insertion position 11. Here, "flared" includes all flared shapes, and does not specifically refer to a precise flared shape. Figure 9 As shown, the first rotating shaft 121 is integrally formed on the panel base 1. The number and position of the first rotating shaft 121 correspond one-to-one with the abutment recess 2421, and each of the first rotating shafts 121 is coaxially arranged.

[0102] Furthermore, when button 21 is pressed, the pressing part 2 will rotate slightly based on the first rotating shaft 121, therefore, as Figure 6 and Figure 7 As shown, the top of the abutment recess 2421 is set to be arc-shaped, and its curvature is consistent with the curvature of the first rotating shaft 121, so that the abutment recess 2421 can fit against the first rotating shaft 121 to rotate, thereby making the pressing feel smoother.

[0103] Furthermore, such as Figures 6-9As shown, the movable latching structure 243 is constructed as a first latch extending from the button 21 toward the second direction. The panel base 1 is provided with a first latching position 13 adapted to the first latch. The movable latching structure 243 latches onto the first latching position 13. The first latching position 13 has reserved space for movement in the second direction, so that the first latch can move toward the second direction.

[0104] According to embodiments of the present invention, such as Figure 3 , Figure 9 and Figure 10 As shown, the pressing part 2 has locking and rotating structures 244 on both sides facing the second direction. The panel base 1 has a second rotating shaft 14 at a corresponding position to the locking and rotating structures 244. The locking and rotating structures 244 are locked to the second rotating shaft 14 and can rotate based on the second rotating shaft 14. The second rotating shaft 14 is coaxially arranged with the first rotating shaft 121. The function of the locking and rotating structures 244 is to improve the connection stability between the pressing part 2 and the panel base 1. When the button 21 is pressed, the locking and rotating structures 244 can also provide support and limiting force, making the pressing movement of the button 21 more stable and reliable. Furthermore, when disassembling or assembling the pressing part 2, if the movable locking structure 243 disengages from the panel base 1, the locking and rotating structures 244 can provide auxiliary locking force to prevent the pressing part 2 from falling off. Figure 10 This is a simplified assembly diagram showing the structure of the pressing part 2 and the panel base 1. Figure 10 Some of the structures in it have been simplified, but Figure 10 The plug-in structure 241, the snap-fit ​​rotating structure 244, and the movable snap-fit ​​structure 243 are in the middle. Figure 3 and Figure 9 To maintain consistency, it should be noted that the plug-in structure 241, the snap-fit ​​rotation structure 244, and the movable snap-fit ​​structure 243 are not on the same vertical plane (by...). Figure 3 It can be seen that... Figure 10 By using a stepped section method to concentrate the three elements on the same cross section, the structure can be displayed more intuitively.

[0105] Furthermore, such as Figure 10 As shown, the snap-fit ​​rotating structure 244 includes a rotating hole 2441 and a snap-fit ​​interface 2442 communicating with the rotating hole 2441. The second rotating shaft 14 is snapped into the rotating hole 2441 by the snap-fit ​​interface 2442. The opening direction of the snap-fit ​​interface 2442 is set as an inclined direction between the second direction and the third direction, wherein the third direction is the direction from the pressing end 23 of the pressing part 2 toward the connecting end 22. The second direction and the third direction are already... Figure 10 The winning bid was selected. Among them, Figure 10The document contains three diagrams, each corresponding to one of three states during the installation of the pressing part 2. The first state is the state where the pressing part 2 is detached; the second state is the state during the installation of the pressing part 2; and the third state is the state where the pressing part 2 is installed. In the second state, the insertion structure 241 of the pressing part 2 is inserted obliquely into the insertion position 11 facing downward to the left. The locking interface 2442 of the locking rotating structure 244 abuts against the second rotating shaft 14, and the movable locking structure 243 has not yet been locked into the panel base 1. At this time, due to the overall tilt of the pressing part 2, the opening direction of the locking interface 2442 is exactly vertically downward. When the pressing part 2 rotates downward based on the insertion structure 241, the movement direction of the locking interface 2442 is exactly consistent with the opening direction of the locking interface 2442, allowing the locking interface 2442 to be smoothly locked into the second rotating shaft 14. Subsequently, the movable locking structure 243 is locked into the first locking position 13, and the installation is completed. Furthermore, the disassembly process of the pressing part 2 is the reverse of the installation process. During disassembly, the movable latching structure 243 is first disengaged from the first latching position 13, and then the pressing part 2 is rotated upward based on the insertion structure 241. This allows the latching rotation structure 244 to disengage from the second rotating shaft 14. At this time, the abutment structure 242 also disengages from the support limiting structure 12, allowing the insertion structure 241 to disengage from the insertion position 11, thereby disassembling the pressing part 2. In this embodiment of the invention, since the opening direction of the latching interface 2442 is inclined, the installation and disassembly process of the pressing part 2 is relatively simple and convenient. Moreover, the latching rotation structure 244 and the abutment structure 242 cooperate to make the pressing part 2 more convenient to be disassembled and installed as a whole, avoiding damage to the connecting end 22 by disassembling each button 21 one by one.

[0106] Furthermore, such as Figure 4 and Figure 3As shown, the buttons 21 at corresponding positions of the connecting end 22 are connected by a connecting structure 25. The connecting structure 25 is recessed in the first surface 27 of the pressing part 2, so that when one button 21 is pressed, the other buttons 21 will not follow suit. The first surface 27 is the side of the pressing part 2 facing away from the second direction. The connecting structure 25 protrudes from the second surface 28 of the pressing part 2 to enhance the connection strength between the buttons 21. The second surface 28 is the side of the pressing part 2 facing the second direction. The first surface 27 is the upper surface of the pressing part 2 in this embodiment, and the second surface 28 is the lower surface of the pressing part 2 in this embodiment. Furthermore, two adjacent buttons 21 are separated by a dividing seam 26. The first surface 27 of the pressing part 2 is provided with a strip groove 251 at the corresponding position of the connecting structure 25. The strip groove 251 extends into the dividing seam 26 to reduce the linkage effect between the two adjacent buttons 21, so that when one of the buttons 21 is pressed, the other buttons 21 will not follow.

[0107] According to embodiments of the present invention, such as Figure 13 and Figure 9As shown, the smart switch 100 also includes a circuit board 5. The panel base 1 covers the bottom shell 3, forming a receiving cavity with the bottom shell 3. The circuit board 5 is housed in the receiving cavity and carries high-voltage and low-voltage circuits. The bottom shell 3 has mounting holes 31 for inserting mounting screws 32, which are used to mount the bottom shell 3 externally. The panel base 1 has an operating hole 15 at a position corresponding to the mounting hole 31. The nuts of the mounting screws 32 are exposed in the operating hole 15. The button 21 covers the operating hole 15 so that the mounting screws 32 can be operated after the button 21 is removed. This invention integrates the high-voltage and low-voltage circuits onto a single circuit board 5, saving space in the bottom shell 3, making the bottom shell 3 smaller, and allowing it to be placed more conveniently in a junction box, thus improving the installation convenience of the smart switch 100. Simultaneously, it also leaves more space in the junction box to accommodate other structures, such as wiring harnesses. However, since the high-voltage and low-voltage circuits are housed on the same circuit board 5, the circuit board 5 cannot be exposed to the outside to prevent electric shock. Therefore, in this invention, the circuit board 5 is enclosed between the panel base 1 and the bottom shell 3, and the panel base 1 does not need to be removed when installing the smart switch 100. In this embodiment, the mounting hole 31 is located within the coverage area of ​​the pressing part 2. When installing the smart switch 100, the user only needs to remove the pressing part 2 to expose the mounting hole 31, and then connect the mounting screw 32 to the wall recess, thereby fixing the smart switch 100 to the wall. The installation process does not require removing the panel base 1, which protects the circuit board 5 from damage and avoids the risk of electric shock from exposed circuit board 5.

[0108] The high-voltage circuit may be, for example, as described in subsequent embodiments, such as... Figure 33 The circuit consists of a relay 40, a first power conversion circuit 501, a zero-crossing detection circuit 60, and terminals for connecting to the target device 200. The low-voltage circuit can be, for example, as shown in the example... Figure 33 The circuit comprises a processing device 30, an infrared detection device 20, a character chip 70, a second power conversion circuit 502, a third power conversion circuit 503, a relay drive circuit 80, etc. The specific circuit principles and connections can be understood by referring to the relevant descriptions in subsequent embodiments.

[0109] According to embodiments of the present invention, such as Figure 15 , Figure 17 and Figure 19As shown, since the circuit board provided in this embodiment carries both high-voltage and low-voltage circuits, it needs to be protected from external exposure when powered on. Therefore, in this embodiment, the panel base 1 includes a disassembly structure 16 for detaching the panel base 1 from the bottom shell 3. The disassembly structure 16 is operable to detach the panel base 1 from the bottom shell 3. The disassembly structure 16 is located on the back of the panel base 1, so that when the smart switch 100 is installed on a wall, the disassembly structure 16 is hidden between the panel base 1 and the wall, preventing the user from removing the panel base 1. This avoids the user accidentally removing the panel base 1, exposing the circuit board 5 and posing a risk of electric shock. The disassembly structure 16 can be a clip, screw, or other operable structure that allows the panel base 1 to be detached from the bottom shell 3.

[0110] In one exemplary embodiment, such as Figure 15 and Figure 17 As shown, the disassembly structure 16 includes a second buckle 161, and the bottom shell 3 is provided with a second snap-fit ​​position 33 adapted to the second buckle 161. The second buckle 161 is fastened to the second snap-fit ​​position 33, and the second buckle 161 can be pried to allow the panel base 1 to be detached from the bottom shell 3. The second buckle 161 is integrally formed on the inner side wall of the panel base 1, and the second snap-fit ​​position 33 is provided on the side of the bottom shell 3 away from the panel base 1, so that when the smart switch 100 is installed on the wall, the second buckle 161 is hidden between the panel base 1 and the wall.

[0111] In another exemplary embodiment, such as Figure 19 As shown, the disassembly structure 16 includes a connecting screw 162. The left end of the panel base 1 is fastened to the bottom shell 3, and the right end is provided with a threaded connection hole adapted to the connecting screw 162. The bottom shell 3 is provided with a countersunk hole adapted to the threaded connection hole. The connecting screw 162 passes through the countersunk hole and connects to the threaded connection hole to achieve a detachable connection between the panel base 1 and the bottom shell 3. The countersunk hole is provided on the side of the bottom shell 3 that is in contact with the wall, and the countersunk hole can accommodate the nut of the connecting screw 162. When the smart switch 100 is installed on the wall, the connecting screw 162 is hidden between the panel base 1 and the wall.

[0112] Existing smart switches typically fix the high-voltage circuit board to the base shell. When installed on a wall, the base shell is prone to deformation towards the wall's interior, causing the high-voltage circuit board to move inwards. In this invention, the high-voltage and low-voltage circuits are concentrated on the same circuit board 5, and the detection element 52 is also located on this circuit board 5. If the circuit board 5 moves inwards towards the wall, the gap between the button 21 and the detection element 52 will increase, potentially causing the button 21 to fail to trigger the detection element 52. Furthermore, significant deformation of the base shell 3 can easily damage the circuit board 5. To solve this problem, according to an embodiment of the invention, such as... Figure 18 and Figure 15 As shown, there is at least one circuit board 5, and each circuit board 5 is fixedly connected to the panel base 1. This ensures that when the bottom shell 3 deforms significantly, it will not directly affect the circuit board 5, thus preventing damage. The bottom shell 3 has mounting holes 31 on opposite sides for external installation. The sides of the bottom shell 3 without mounting holes 31 are connected to the panel base 1. This reduces the deformation of the panel base 1 and the circuit board 5 when the bottom shell 3 deforms during installation, ensuring that the button 21 can accurately trigger the detection element 52 even when the bottom shell 3 is deformed. Figure 18 This is a simplified cross-sectional view of the intelligent switch 100. Figure 18 It contains two diagrams. The first diagram is a structural schematic of the bottom shell 3 before deformation, and the second diagram is a structural schematic of the bottom shell 3 after deformation.

[0113] In a specific embodiment, the bottom shell 3 includes a first side and a second side disposed opposite to each other, and a first end and a second end disposed opposite to each other. The first side, the first end, the second side and the second end are sequentially adjacent to each other surrounding the bottom shell 3. The first side and the second side are respectively provided with the mounting holes 31, and the first end and the second end are respectively connected to the panel base 1. When the bottom shell 3 is installed externally through the mounting hole 31, the first end and the second end of the bottom shell 3 abut against the wall and are supported by the wall. The mounting hole 31 is connected to the junction box by mounting screws 32. If the mounting screws 32 are tightened too much, the first side and the second side of the bottom shell 3 will be driven by the mounting screws 32 and deform downward. At this time, the first end and the second end of the bottom shell 3 change a small range because they are supported by the wall. Since the panel base 1 is connected to the first end and the second end, but not to the first side and the second side, the panel base 1 is minimally affected by the deformation of the bottom shell 3. Since the circuit board 5 is fixedly connected to the panel base 1, the first circuit board 5 is less affected by the deformation of the bottom shell 3, thus ensuring that the first circuit board 5 will not deform downward with the bottom shell 3. This ensures that the relative positional relationship between the button 21 on the panel base 1 and the circuit board 5 is not affected by the deformation of the bottom shell 3, and that the button 21 can accurately trigger the detection element 52 even when the bottom shell 3 is deformed.

[0114] Furthermore, the bottom shell 3 does not provide direct fixing constraints to the circuit board 5, so as to further reduce the impact of deformation of the bottom shell 3 on the circuit board 5.

[0115] Furthermore, such as Figure 15 As shown, the panel base 1 and the bottom shell 3 are detachably connected, so that when the panel base 1 is detached from the bottom shell 3, each of the circuit boards 5 is also detached from the bottom shell 3 along with the panel base 1. Therefore, during assembly, only the circuit boards 5 need to be fixed to the panel base 1, and the bottom shell 3 can be quickly and easily snapped onto the panel base 1 to complete the assembly, improving assembly efficiency. The connection method between the panel base 1 and the bottom shell 3 can be a snap-fit ​​connection, a screw connection, etc. In a specific embodiment, the first end and the second end of the bottom shell 3 are respectively provided with a second snap-fit ​​position 33, and the panel base 1 is provided with a second buckle 161 that cooperates with the second snap-fit ​​position 33. The second buckle 161 is snapped onto the second snap-fit ​​position 33.

[0116] According to embodiments of the present invention, such as Figures 15-16 and Figure 11 As shown, there is one circuit board 5. The circuit board 5 is connected to external wires and carries both high-voltage and low-voltage circuits. The circuit board 5 includes a relay 40, a power supply circuit 50, and a detection element 52. The power supply circuit 50 is electrically connected to the external wires and converts AC power to DC power. The detection element 52 is used for detection and control. The relay 40 is electrically connected to the detection element 52 and can switch its on / off state in response to the detection element 52 being controlled. In a specific embodiment, the lower surface of the circuit board 5 has multiple terminals 53. The terminals 53 connect to the neutral wire, the live wire, and the wires controlling the on / off state of the target device 200. The power supply circuit 50 and the relay 40 are located on the lower surface of the circuit board 5. The power supply circuit 50 is electrically connected to the terminals 53 and can convert 220V AC power to low-voltage DC power to supply power to the low-voltage circuits. The power supply circuit 50 consists of electronic components such as a transformer, capacitor, inductor, and resistor. Figure 16 This is a bottom view of the circuit board 5. Figure 16 The electronic components within the dashed box constitute the power supply circuit 50 (the specific working principle and circuit connection relationship of the power supply circuit 50 can be found in the following text). Figure 33 (This is understood in accordance with the power supply circuit 50 described in the corresponding embodiment). The number of relays 40 is equal to the number of buttons 21. The relays 40 are electrically connected to the terminal block 53 and are used to control the on / off state of the target device 200.

[0117] The working principle and driving principle of the relay 40 can be referred to in the following embodiments, such as Figure 33 and Figure 34 Understand the corresponding records.

[0118] Furthermore, such as Figure 15 and Figure 17 As shown, the terminal block 53 is soldered to the lower surface of the circuit board 5. The bottom shell 3 is provided with a wiring groove 34 at the corresponding position of each terminal block 53. Each terminal block 53 is accommodated in each wiring groove 34. A wiring hole is opened at the bottom of the wiring groove 34. The wire passes through the wiring hole and connects to the terminal block 53. A locking hole is opened on the side of the wiring groove 34. The wiring screw of the terminal block 53 is exposed in the locking hole, so that the user can lock the wiring screw through the locking hole.

[0119] Furthermore, since each terminal 53 must be accommodated in each terminal slot 34, and the position of the locking hole must correspond to the terminal screw, the relative positional accuracy between the terminal 53 and the terminal slot 34 requires high precision. Therefore, as follows: Figure 16 and Figure 15 As shown, in this embodiment, a long strip-shaped first positioning hole 54 is provided between each wiring terminal 53, and a long strip-shaped positioning rib 341 is provided between each wiring groove 34 of the bottom shell 3. The positioning rib 341 is inserted into the first positioning hole 54 to position the bottom shell 3 and the circuit board 5. The positioning rib 341 extends from bottom to top so that when the bottom shell 3 deforms downward, the positioning rib 341 will not affect the circuit board 5.

[0120] Furthermore, such as Figure 9 and Figure 11 As shown, the detection element 52 is disposed on the side of the circuit board 5 facing the button 21. A trigger hole 17 is provided on the panel base 1 at the corresponding position of the detection element 52. A trigger post 211 is provided on the button 21 facing the detection element 52, and the trigger post 211 passes through the trigger hole 17 and abuts against the detection element 52. The number of detection elements 52, trigger posts 211, and trigger holes 17 corresponds to the number of buttons 21.

[0121] According to embodiments of the present invention, such as Figure 15 and Figure 18 As shown, the circuit board 5 is fixedly connected to the panel base 1 by a plurality of fixing screws 554. The bottom shell 3 is provided with a relief recess 35 at the corresponding position of the fixing screws 554. The relief recess 35 is used to accommodate the nuts of the fixing screws 554, so that the circuit board 5 can be close to the bottom shell 3, thereby reducing the thickness of the panel base. Here, "close" can be understood as the distance between the circuit board 5 and the bottom shell 3 being within 2mm. In one embodiment, the circuit board 5 is attached to the upper surface of the bottom shell 3.

[0122] Furthermore, such as Figure 11 As shown, the panel base 1 is provided with two second positioning posts 181, multiple second threaded connection holes 182, and three square protrusions 183 facing the circuit board 5. The circuit board 5 is provided with a second positioning hole 551, a second connecting through hole 552, and a square hole 553 corresponding to each other. The second positioning posts 181 are inserted into the second positioning holes 551 to position the circuit board 5 and the panel base 1. The fixing screw 554 passes through the second connecting through hole 552 and connects to the second threaded connection hole 182 to fix the circuit board 5 to the panel base 1. The square hole 553 is used to accommodate the square protrusion 183. The square protrusion 183 is provided with a first snap-fit ​​position 13 and is hollow, providing space for the movable snap-fit ​​structure 243 to move.

[0123] According to embodiments of the present invention, such as Figure 15 and Figure 16 As shown, a wireless communication module 56 is provided on the side of the circuit board 5 facing away from the panel substrate 1. No copper foil is laid on the circuit board 5 at the position corresponding to the wireless communication module 56, so that the wireless signal can pass through the circuit board 5 and the circuit board 5 can avoid shielding the wireless signal.

[0124] Since the circuit board 5 of this invention carries a high-voltage circuit, there is a certain probability that the high voltage on the circuit board 5 will be transmitted to the mounting screw 32 along the surface of the insulating material. Therefore, sufficient creepage distance needs to be designed to prevent current leakage from the circuit board 5 to the mounting screw 32. Creepage distance is the shortest spatial distance measured along the surface of the insulating material between two conductive components. According to an embodiment of the present invention, as... Figure 15 and Figure 13 As shown, the bottom shell 3 has an isolation wall 36 protruding around the mounting hole 31 towards the panel base 1. The circuit board 5 is disposed on the outside of the isolation wall 36. The isolation wall 36 surrounds the mounting hole 31. The current on the circuit board 5 needs to cross the isolation wall 36 to reach the mounting screw 32, thereby increasing the creepage distance between the circuit board 5 and the mounting screw 32 and preventing the user from touching the mounting screw 32 and getting an electric shock.

[0125] Existing switches with displays typically place the display between a panel base and a transparent cover. The panel base limits the sides of the display, and the transparent cover covers the top surface of the display to secure it. The transparent cover is also adhered to both the panel base and the display. When the display needs to be removed, the transparent cover must be removed first, which is difficult. Furthermore, when there are multiple displays, this method of securing them makes it difficult to remove one display individually without affecting the others, making it unsuitable for the smart switch with multiple displays provided by this invention. Therefore, according to embodiments of the present invention, as... Figure 14 , Figure 11and Figure 12 As shown, a circuit board 5 is provided on the side of the panel base 1 away from the pressing part 2. The display screen 101 is disposed between the panel base 1 and the circuit board 5 and is electrically connected to the circuit board 5. The display screen 101 has a third surface 1011 away from the circuit board 5. The side of the display screen 101 and the third surface 1011 abut against the panel base 1, so that the display screen 101 is limited by the panel base 1. A display area 1012 is provided on the third surface 1011. A display through hole 191 is provided on the panel base 1 at the position directly opposite to the display area 1012. A transparent cover plate 4 is provided on the side of the panel base 1 away from the circuit board 5. The transparent cover plate 4 covers the display through hole 191. The content displayed in the display area 1012 is displayed to the outside through the display through hole 191 and the transparent cover plate 4. In this embodiment of the invention, the display screen 101 is installed into the panel base 1 from the side of the panel base 1 away from the transparent cover plate 4 and is confined between the panel base 1 and the circuit board 5. When disassembling the display screen 101, only the circuit board 5 needs to be removed to disassemble each display screen 101 individually. The disassembly of the display screen 101 will not affect the assembly state of other display screens 101, which is more suitable for the structure of multiple display screens 101 in this embodiment of the invention. Moreover, the transparent cover plate 4 does not need to be removed during the disassembly process, which reduces the difficulty of disassembly and assembly.

[0126] The statement that the display screen 101 abuts against the panel substrate 1 can be understood as the display screen 101 directly abutting against the panel substrate 1 or indirectly abutting against the panel substrate 1 through other structures. In one embodiment, such as... Figure 14 As shown, a first double-sided adhesive (not shown) is provided between the display screen 101 and the panel substrate 1. The display screen 101 is adhered to the panel substrate 1 by the first double-sided adhesive. The first double-sided adhesive covers the periphery of the third surface 1011, so that the third surface 1011 is sealed to the lower side of the display through hole 191. Additionally, as... Figure 20 As shown, the transparent cover plate 4 is attached to the upper side of the display through hole 191 with adhesive 41, so that the upper and lower sides of the display through hole 191 are sealed by the transparent cover plate 4 and the display screen 101 respectively, thereby preventing dust and moisture from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect.

[0127] Furthermore, such as Figure 12 As shown, the panel base 1 has abutment ribs 192 around the sides of the display screen 101. The abutment ribs 192 abut against the sides of the display screen 101 to limit the sides of the display screen 101.

[0128] Furthermore, such as Figure 11As shown, the circuit board 5 is fixedly connected to the panel base 1 by a plurality of fixing screws 554 to facilitate the installation and removal of the circuit board 5, thereby facilitating the installation and removal of the display screen 101. The display screen 101 and the circuit board 5 are connected by a ribbon cable 1013 to disconnect the display screen 101 from the circuit board 5 when it is disassembled. This improves the efficiency of replacing the display screen 101.

[0129] According to embodiments of the present invention, such as Figure 14 As shown, the circuit board 5 is provided with a ribbon cable connection terminal 57, and the display screen 101 is provided with a ribbon cable 1013 facing the third direction. The ribbon cable 1013 is bent and inserted into the ribbon cable connection terminal 57. The third direction is the direction from the pressing end 23 of the pressing part 2 towards the connecting end 22. The third direction has already been... Figure 14 The present invention has been approved. In this embodiment, the ribbon cable 1013 of the display screen 101 is oriented away from the button 21, so that the distance between the display screen 101 and the button 21 is closer and the indication effect is better; and the ribbon cable 1013 and the pressing part 2 are not stacked in the thickness direction, so as to reduce the thickness of the smart switch 100 and avoid the movement of the pressing part 2 causing the ribbon cable 1013 to move and be damaged.

[0130] Furthermore, such as Figure 14 and Figure 11 As shown, a supporting foam 59 is provided between the display screen 101 and the circuit board 5, providing support for the display screen 101. The upper end of the supporting foam 59 abuts against and is attached to the display screen 101, while the lower end abuts against the circuit board 5. The supporting foam 59 is in a compressed state, thereby providing support for the display screen 101 and making the connection between the display screen 101 and the panel substrate 1 more stable. The ribbon cable connection terminal 57 is located below the supporting foam 59 and is covered by the supporting foam 59, making the connection between the ribbon cable 1013 and the ribbon cable connection terminal 57 more stable.

[0131] According to embodiments of the present invention, such as Figure 20 and Figure 5 As shown, a light-shielding layer 42 is provided on the side of the transparent cover plate 4 facing the panel substrate 1; a display window 421 is opened on the light-shielding layer 42 directly opposite the display area 1012, and the content displayed in the display area 1012 is displayed to the outside through the display window 421; wherein, the light-shielding layer 42 is specifically a black coating, which is printed on the back of the transparent cover plate 4 by screen printing. The function of the light-shielding layer 42 is to cover the internal structure and improve the aesthetics. Since the circuit board 5 is equipped with high-voltage circuits and low-voltage circuits, the display screen 101 is considered to be a live body, and the creepage distance between the display screen 101 and the outer surface of the switch must be greater than 2mm to avoid electric shock to the user. Therefore, as Figure 14As shown, a preset gap is provided between the transparent cover plate 4 and the display screen 101, thereby increasing the creepage distance between the display screen 101 and the upper surface of the transparent cover plate 4. In one embodiment, the preset gap is 1.2 mm, and the thickness of the transparent cover plate 4 is 2 mm.

[0132] However, due to the existence of the preset gap, when the smart switch 100 is installed on the wall, the upper part of the display area 1012 will be partially blocked by the light-shielding layer 42 (e.g., Figure 21 As shown, since the smart switch 100 is installed on the wall at a position generally lower than eye level, the viewing angle of the human eye when looking at the display screen 101 is a downward tilted angle, causing the upper edge of the display window 421 to obscure a portion of the display area 1012. Therefore, a blank area is provided at one end of the display area 1012 facing the fourth direction. Figure 21 (Not shown in the image), no content is displayed in the blank area to avoid the content being blocked by the light-shielding layer 42; wherein, the fourth direction is the same as the vertical upward direction when the smart switch 100 is installed on the wall, in this embodiment, the fourth direction is the same as the third direction, and the fourth direction has been... Figure 21 The blank area is marked as the upper horizontal area of ​​the display area 1012 (i.e., ...). Figure 37 (The area not displayed in the text). Furthermore, such as... Figure 21 As shown, the display window 421 is positioned directly opposite the display area 1012. The size of the display window 421 is slightly larger than the size of the display area 1012 to reduce the amount of obstruction of the display area 1012 by the display window 421.

[0133] According to embodiments of the present invention, such as Figure 6 As shown, the transparent cover plate 4 and the connecting end 22 of the pressing part 2 are arranged side by side, and the side of the transparent cover plate 4 facing the fifth direction is flush with the side of the pressing part 2 facing the fifth direction. In one embodiment, when the pressing part 2 is not pressed, both the transparent cover plate 4 and the pressing part 2 are... Figure 6 The horizontal state in the middle.

[0134] According to embodiments of the present invention, such as Figure 11 and Figure 20As shown, the circuit board 5 is equipped with an infrared detection device 20, which includes an infrared emitting unit 201 for emitting a detection wave and an infrared receiving unit 202 for triggering the display screen 101 upon receiving the detection wave. The infrared detection device 20 detects the distance between an external object and the smart switch 100. When the distance is sufficiently close, the display screen 101 is triggered. Specifically, the detection wave emitted by the infrared emitting unit 201 is reflected by the external object and transmitted to the infrared receiving unit 202. The closer the external object is to the infrared receiving unit 202, the stronger the intensity of the reflected detection wave detected by the infrared receiving unit 202. When the intensity of the detection wave detected by the infrared receiving unit 202 is greater than a threshold, the smart switch 100 determines that the distance between the external object and the smart switch 100 is less than a predetermined distance, and then controls the display screen 101 to light up. The detection wave can be an infrared light wave or other electromagnetic waves. Furthermore, the transparent cover plate 4 covers the infrared emitting unit 201 and the infrared receiving unit 202, and the detection wave passes through the transparent cover plate 4 for external detection.

[0135] The inventors discovered that the detection wave emitted by the infrared emitting unit 201 can easily be transmitted from the inside of the smart switch 100 to the infrared receiving unit through two erroneous paths, causing the infrared detection device 20 to misjudge. One path is that the detection wave is transmitted to the infrared receiving unit 202 via total internal reflection inside the transparent cover plate 4; the other is that the detection wave passes through the gap between the panel substrate 1 and the circuit board 5 to the infrared receiving unit 202, or, when the panel substrate 1 is thin and light-colored, the detection wave directly penetrates the panel substrate 1 to the infrared receiving unit 202. To mitigate these two erroneous transmission paths, the present invention adopts the following solution: Figure 20 , Figure 11 and Figure 6 As shown, the infrared emitting unit 201 includes an infrared LED 2012, and the infrared receiving unit 202 includes an infrared receiver 2021. At least one display screen 101 is disposed between the infrared LED 2012 and the infrared receiver 2021, thereby increasing the distance between them and reducing the total internal reflection of the detection wave inside the transparent cover plate 4. A shielding member 58 is arranged around the infrared LED 2012 to block the detection wave from the side of the LED 2012, thus reducing the transmission of the detection wave through the gap between the panel substrate 1 and the circuit board 5 or through the panel substrate 1 to the infrared receiver 202. These two methods reduce the transmission of the detection wave inside the smart switch 100, preventing false detection by the infrared detection device 20.

[0136] It is worth mentioning that increasing the distance between the infrared receiver 2021 and the infrared LED 2012 can, to a certain extent, prevent small objects such as flies and mosquitoes from accidentally triggering the infrared detection device 20. Specifically, when flies and mosquitoes rest on the switch surface, because of their small size, their bodies can only cover either the infrared LED 2012 or the infrared receiver 2021, which is insufficient to trigger the infrared detection device 20.

[0137] In one embodiment, such as Figure 20 As shown, there are three display screens 101, which are arranged at intervals along the first direction. The infrared light-emitting tube 2012 is disposed between the left display screen 101 and the middle display screen 101, and the infrared receiver 2021 is disposed between the middle display screen 101 and the right display screen 101.

[0138] Furthermore, such as Figure 6 , Figure 11 and Figure 20 As shown, the shielding member 58 is a black annular foam surrounding the infrared LED 2012. The upper end of the annular foam abuts against the adhesive 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, thereby blocking the detection wave from passing through the annular foam from the side. It is worth noting that, since the annular foam is a flexible material, it can fit tightly against the circuit board 5, preventing the detection wave from propagating out through the gap between the annular foam and the circuit board 5. Furthermore, the panel substrate 1 has a transmitting through-hole 193 and a receiving through-hole 194 at corresponding positions of the annular foam and the infrared receiver 2021. The transmitting through-hole 193 accommodates the annular foam and limits its position, while the receiving through-hole 194 accommodates the infrared receiver 2021.

[0139] Furthermore, such as Figure 20 and Figure 5As shown, the light-shielding layer 42 has an emission window 422 directly opposite the infrared LED 2012, and a receiving window 423 directly opposite the infrared receiver 2021. The infrared receiver 2021 receives external detection waves through the receiving window 423; the infrared LED 2012 emits detection waves through the emission window 422, and the emission angle of the detection waves is limited to less than 90° by the emission window 422. When the distance between the infrared LED 2012 and the light-shielding layer 42 is fixed, the smaller the size of the emission window 422, the smaller the emission angle of the detection waves, and the smaller the detection angle of the infrared detection device 20. When the size of the emission window 422 is constant, the larger the distance between the infrared LED 2012 and the transparent cover plate 4, the smaller the emission angle of the detection waves, and the smaller the detection angle of the infrared detection device 20. By controlling the size of the emission window 422 and the distance between the infrared LED 2012 and the transparent cover plate 4, the detection angle of the infrared detection device 20 can be accurately controlled. In this embodiment of the invention, the detection angle of the infrared detection device 20 is controlled to be less than 90°. This is because if the detection angle is too large, the infrared detection device 20 is easily triggered falsely. Conversely, if the detection angle is too small, the smart switch 100 may not trigger when the user approaches it from the side. Therefore, the inventors, through experimental verification, controlled the detection angle to be between 30° and 60° to achieve a suitable triggering range.

[0140] Furthermore, such as Figure 20 As shown, the adhesive 41 of the transparent cover plate 4 has a first adhesive hole 411, a second adhesive hole 412, and a third adhesive hole 413 respectively at the positions directly opposite the display window 421, the transmitting window 422, and the receiving window 423. The size of the first adhesive hole 411, the second adhesive hole 412, and the third adhesive hole 413 is larger than the size of the display window 421, the transmitting window 422, and the receiving window 423.

[0141] In another embodiment, such as Figure 22 As shown, this embodiment is similar to Figures 1-21 The difference in this embodiment is that the engagement between the plug-in structure 241 and the plug-in position 11 is relatively loose. When the button 21 is pressed, the pressing part 2 will pivot based on the first pivot 121, and the plug-in structure 241 no longer provides a restoring force. A restoring foam 29 is provided between each button 21 and the panel base 1, and the restoring force is provided through the restoring foam 29. Compared with a spring, foam has the characteristic of slow rebound. Using foam to provide the restoring force can make the pressing feel of the button 21 have a damped feel, making the pressing feel more advanced. Furthermore, a foam mounting position 291 is provided on the lower surface of the button 21, and the restoring foam 29 is attached to the foam mounting position 291. Furthermore, in the first direction, reinforcing ribs are provided on both sides of each button 21 to enhance the rigidity of the button 21.

[0142] Furthermore, such as Figure 22 As shown, each button 21 has a thinning slope 261 on the side adjacent to other buttons 21. The thinning slope 261 is used to reduce the thickness of the edge of the button 21, making the button 21 thinner near the connecting structure 25, thereby reducing the linkage effect between the buttons 21, that is, the movement of one button 21 will not drive the movement of other adjacent buttons 21. In addition, the thinning slope 261 on the button 21 can also increase the width of the injection mold at this part, thereby making the injection mold corresponding to this part less prone to damage. Specifically, if the button 21 does not have the thinning slope 261, the injection mold at the position corresponding to the dividing seam 26 will be a thin strip, which is easy to damage. The thinning slope 261 reduces the thickness of the button 21 at the position corresponding to the dividing seam 26, and the injection mold at this position becomes wider, thereby increasing the strength of the injection mold.

[0143] In another embodiment, such as Figure 23 As shown in the figure, the transparent cover 4 is not displayed. This embodiment is a two-button version of the smart switch 100. This embodiment is similar to... Figures 1-21 The difference in this embodiment is that there are two buttons 21, and correspondingly, there are two displays 101, two relays 40, two detection elements 52, two trigger holes 17, and two trigger posts 211. The infrared LED 2012 is positioned between the two displays 101, and the infrared receiver 2021 is positioned on the right side of the right display 101, increasing the distance between the infrared LED 2012 and the infrared receiver 2021. This reduces the total internal reflection of the detection wave inside the transparent cover 4, preventing misjudgment by the infrared detection device 20. The displays 101, infrared LED 2012, and infrared receiver 2021 are arranged side-by-side along a first direction. The panel substrate 1 has display through holes 191, emission through holes 193, and reception through holes 194 respectively at the corresponding positions of the display area 1012 of the displays 101, the infrared LED 2012, and the infrared receiver 2021. The positions of the display window 421, the transmitting window 422, and the receiving window 423 on the light-shielding layer 42 correspond to the positions of the display through-hole 191, the transmitting through-hole 193, and the receiving through-hole 194. Each button 21 is provided with one of the aforementioned movable latching structures 243. The number and position of the first latching positions 13 on the panel base 1 are the same as those of the three-button version of the smart switch 100, both being three. The first latching positions 13 on the left and right sides of the panel base 1 are respectively latched into the movable latching structures 243 of the two buttons 21.

[0144] In another embodiment, such as Figure 24 As shown in the figure, the transparent cover 4 is not displayed; this embodiment is a single-button version of the smart switch 100. This embodiment is similar to... Figures 1-21The difference in this embodiment is that there is only one button 21, and correspondingly, there is one display screen 101, one relay 40, one detection element 52, one trigger hole 17, and one trigger post 211. The infrared LED 2012 is located on the left side of the display screen 101, and the infrared receiver 2021 is located on the right side of the display screen 101. This increases the distance between the infrared LED 2012 and the infrared receiver 2021, thereby reducing the total internal reflection of the detection wave inside the transparent cover plate 4 and preventing misjudgment by the infrared detection device 20. The display screen 101, the infrared LED 2012, and the infrared receiver 2021 are arranged side-by-side along a first direction. The panel substrate 1 has display through holes 191, emission through holes 193, and reception through holes 194 respectively at the corresponding positions of the display area 1012 of the display screen 101, the infrared LED 2012, and the infrared receiver 2021. The positions of the display window 421, the transmitting window 422, and the receiving window 423 on the light-shielding layer 42 correspond to the positions of the display through-hole 191, the transmitting through-hole 193, and the receiving through-hole 194. The button 21 is provided with two of the aforementioned movable latching structures 243. The number and position of the first latching positions 13 on the panel base 1 are the same as those of the three-button version of the smart switch 100, both being three. The first latching positions 13 on the left and right sides of the panel base 1 are respectively latched onto the two movable latching structures 243 of the button 21.

[0145] Furthermore, existing smart wall switches generally include a high-voltage board and a low-voltage board. The high-voltage board carries the high-voltage circuitry, converting 220V AC power to DC power to supply the circuit, and also includes relays that control the on / off state of target devices. The low-voltage board carries the low-voltage circuitry, typically housing control chips, detection components, and wireless communication modules. When installing a smart wall switch, the front panel must be removed before the back cover can be installed on the wall. Since the high-voltage board is located on the back cover and the low-voltage board on the front panel, removing the front panel also pulls down the low-voltage board. The low-voltage board and high-voltage board are connected via pin headers and sockets, which makes it easy to damage the pin headers when the front panel is installed on the back cover, causing inconvenience during installation. Therefore, this invention also provides a smart switch to solve the above problems. The accompanying drawings in this embodiment will be the same as those in the above embodiments.

[0146] like Figure 9 , Figure 13 and Figures 22-24As shown, the smart switch 100 includes a bottom shell 3, a panel base 1, a circuit board 5, and a button 21. The bottom shell 3 has a mounting hole 31 for inserting a mounting screw 32, and the bottom shell 3 is externally mounted via the mounting screw 32. The panel base 1 covers the bottom shell 3, forming a receiving cavity with the bottom shell 3. The circuit board 5 is housed in the receiving cavity and carries high-voltage and low-voltage circuits. The button 21 is detachably connected to the panel base 1 for operation. The panel base 1 has an operating hole 15 corresponding to the mounting hole 31, and the nut of the mounting screw 32 is exposed in the operating hole 15. The button 21 covers the operating hole 15 so that the mounting screw 32 can be operated after the button 21 is removed. The technical details of the bottom shell 3, panel base 1, circuit board 5, and button 21 have been described in detail above and will not be repeated here. This invention integrates high-voltage and low-voltage circuits onto a single circuit board 5, saving space in the base shell 3 and making it smaller. This allows the base shell 3 to be placed more conveniently within a junction box, improving the ease of installation of the smart switch 100. It also allows more space within the junction box to accommodate other structures, such as wiring harnesses. However, since the high-voltage and low-voltage circuits are housed on the same circuit board 5, the circuit board 5 cannot be exposed to prevent electric shock. Therefore, the circuit board 5 of this invention is enclosed between the panel base 1 and the base shell 3, and the panel base 1 does not need to be removed when installing the smart switch 100. In this embodiment, the mounting hole 31 is located within the coverage area of ​​the pressing part 2. When installing the smart switch 100, the user only needs to remove the pressing part 2 to expose the mounting hole 31, and then connect the mounting screw 32 to the junction box in the wall, thereby fixing the smart switch 100 to the wall. The installation process does not require removing the panel base 1, protecting the circuit board 5 from damage and avoiding the risk of electric shock from exposed circuit board 5.

[0147] Furthermore, such as Figure 15 , Figure 17 and Figure 19As shown, since the circuit board provided in this embodiment carries both high-voltage and low-voltage circuits, it needs to be protected from external exposure when powered on. Therefore, in this embodiment, the panel base 1 includes a disassembly structure 16 for detaching the panel base 1 from the bottom shell 3. The disassembly structure 16 is located on the back of the panel base 1, so that when the smart switch 100 is installed on a wall, the disassembly structure 16 is hidden between the panel base 1 and the wall, preventing the user from removing the panel base 1. This avoids the user accidentally removing the panel base 1, exposing the circuit board 5 and posing a risk of electric shock. The disassembly structure 16 can be operated to detach the panel base 1 from the bottom shell 3. The disassembly structure 16 can be a clip, screw, or other structure that can be operated to detach the panel base 1 from the bottom shell 3.

[0148] In one exemplary embodiment, such as Figure 15 and Figure 17 As shown, the disassembly structure 16 includes a second buckle 161, and the bottom shell 3 is provided with a second snap-fit ​​position 33 adapted to the second buckle 161. The second buckle 161 is fastened to the second snap-fit ​​position 33, and the second buckle 161 can be pried to allow the panel base 1 to be detached from the bottom shell 3. The second buckle 161 is integrally formed on the inner side wall of the panel base 1, and the second snap-fit ​​position 33 is provided on the side of the bottom shell 3 away from the panel base 1, so that when the smart switch 100 is installed on the wall, the second buckle 161 is hidden between the panel base 1 and the wall.

[0149] In another exemplary embodiment, such as Figure 19 As shown, the disassembly structure 16 includes a connecting screw 162. The left end of the panel base 1 is fastened to the bottom shell 3, and the right end is provided with a threaded connection hole adapted to the connecting screw 162. The bottom shell 3 is provided with a countersunk hole adapted to the threaded connection hole. The connecting screw 162 passes through the countersunk hole and connects to the threaded connection hole to achieve a detachable connection between the panel base 1 and the bottom shell 3. The countersunk hole is provided on the side of the bottom shell 3 that is in contact with the wall, and the countersunk hole can accommodate the nut of the connecting screw 162. When the smart switch 100 is installed on the wall, the connecting screw 162 is hidden between the panel base 1 and the wall.

[0150] According to embodiments of the present invention, such as Figure 18 and Figure 15As shown, the circuit board 5 is fixedly connected to the panel base 1. The mounting holes 31 are located on opposite sides of the bottom shell 3. The sides of the bottom shell 3 without the mounting holes 31 are used to connect to the panel base 1. This reduces the deformation of the panel base 1 and the circuit board 5 when the bottom shell 3 deforms during installation, preventing damage to the circuit board 5. It also ensures that the button 21 can trigger the smart switch 100 even when the bottom shell 3 deforms. The technical details of the mounting holes 31, the bottom shell 3, and the panel base 1 have been described in detail above and will not be repeated here.

[0151] Furthermore, such as Figure 16 , Figure 11 , Figure 6 and Figure 9 As shown, the circuit board 5 is equipped with a relay 40, a power supply circuit 50, and a detection element 52. The power supply circuit 50 is electrically connected to an external wire and is used to convert AC power to DC power. The detection element 52 is used for detection and control. The relay 40 is electrically connected to the detection element 52 and can switch on / off states in response to the detection element 52 being controlled. The detection element 52 is disposed on the side of the circuit board 5 facing the button 21. The panel base 1 has a trigger hole 17 at the corresponding position of the detection element 52. The button 21 has a trigger post 211 facing the detection element 52, and the trigger post 211 passes through the trigger hole 17 and abuts against the detection element 52. The technical details of the power supply circuit 50, the detection element 52, the trigger post 211, and the trigger hole 17 have been described in detail above and will not be repeated here.

[0152] Furthermore, such as Figure 23 As shown, a reset foam 29 is provided between each of the buttons 21 and the panel base 1. The reset foam 29 is used to provide a reset force. Compared with a spring, foam has the characteristic of slow rebound. Using foam to provide the reset force can make the button 21 have a damped feel when pressed, resulting in a more sophisticated pressing experience. The technical details of the reset foam 29 have been described in detail above and will not be repeated here.

[0153] According to embodiments of the present invention, such as Figures 1-5 As shown, there are multiple buttons 21, and the smart switch 100 also includes multiple displays 101 corresponding to each button 21. Each display 101 is disposed on the panel base 1 and electrically connected to the circuit board 5. Each display 101 is used to display the button information of the corresponding button 21. Further, as... Figure 6 , Figure 3 and Figure 9As shown, the end of the button 21 closest to the display screen 101 is connected to the panel base 1, and the button 21 can move with the end closest to the display screen 101 as a fulcrum; the end of the button 21 away from the display screen 101 facing the circuit board 5 is provided with a movable latching structure 243, and the panel base 1 is provided with a first latching position 13 adapted to the movable latching structure 243. The movable latching structure 243 latches into the first latching position 13, and the first latching position 13 has reserved space for movement, so that the movable latching structure 243 can move toward the circuit board 5. In this embodiment of the invention, the display screen 101 is installed into the panel base 1 from the side opposite to the transparent cover plate 4 and is confined between the panel base 1 and the circuit board 5. When disassembling the display screen 101, only the circuit board 5 needs to be removed to disassemble each display screen 101 individually. The disassembly of the display screen 101 will not affect the assembly state of other display screens 101, which is more suitable for the structure of multiple display screens 101 in this embodiment of the invention. Moreover, the transparent cover plate 4 does not need to be removed during the disassembly process, reducing the difficulty of disassembly and assembly. The technical details of the button 21, display screen 101, movable latching structure 243 and first latching position 13 have been described in detail above and will not be repeated here.

[0154] Furthermore, such as Figure 20 and Figure 6 As shown, the smart switch 100 also includes a transparent cover plate 4, which is disposed on the panel base 1. Each of the display screens 101 is covered by the transparent cover plate 4, and the display screens 101 display content to the outside through the transparent cover plate 4. The transparent cover plate 4 is disposed at the end of each of the buttons 21, and the side of the transparent cover plate 4 facing away from the second direction is flush with the side of the button 21 facing away from the second direction. The second direction is the same as the direction in which the button 21 is pressed. The technical details of the transparent cover plate 4 have been described in detail above and will not be repeated here.

[0155] According to embodiments of the present invention, such as Figure 11 , Figure 12 and Figure 14As shown, the smart switch 100 includes a display screen 101, which is disposed on the panel base 1 and electrically connected to the circuit board 5. The display screen 101 is used to display the button information of the button 21. The display screen 101 is disposed between the panel base 1 and the circuit board 5. The display screen 101 has a third surface 1011 facing away from the circuit board 5. The side of the display screen 101 and the third surface 1011 respectively abut against the panel base 1, so that the display screen 101 is limited by the panel base 1. A supporting foam 59 is provided between the display screen 101 and the circuit board 5, and the supporting foam 59 provides support for the display screen 101. The technical details of the display screen 101, the panel base 1, and the supporting foam 59 have been described in detail above and will not be repeated here.

[0156] Furthermore, such as Figure 14 As shown, a first double-sided adhesive (not shown) is provided between the display screen 101 and the panel substrate 1. The display screen 101 is adhered to the panel substrate 1 by the first double-sided adhesive. The first double-sided adhesive covers the periphery of the third surface 1011, so that the third surface 1011 is sealed to the lower side of the display through hole 191. Additionally, as... Figure 20 As shown, the transparent cover plate 4 is attached to the upper side of the panel substrate 1 with adhesive 41, so that the upper and lower sides of the display through hole 191 are sealed by the transparent cover plate 4 and the display screen 101 respectively, thereby preventing dust and moisture from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect. The technical details of the first double-sided adhesive have been described in detail above and will not be repeated here.

[0157] Furthermore, existing smart wall switches typically have at least one circuit board fixedly connected to the base. When the base is installed on the wall, overtightening the mounting screws can cause the base to deform inwards towards the wall, resulting in deformation of the circuit board. Excessive deformation of the base can damage the circuit board. Therefore, this invention also provides a smart switch to solve the above problems. The accompanying drawings in this embodiment will be the same as those in the above embodiments.

[0158] like Figure 18 and Figure 15As shown, the smart switch 100 includes a base shell 3, a panel base 1, and at least one circuit board 5. The panel base 1 covers the base shell 3. Each circuit board 5 is fixedly connected to the panel base 1. The base shell 3 has mounting holes 31 on opposite sides for external installation. The sides of the base shell 3 without mounting holes 31 are connected to the panel base 1. This reduces the deformation of the panel base 1 and the circuit boards 5 when the base shell 3 deforms during installation. The technical details of the base shell 3, panel base 1, and circuit boards 5 have been described in detail above and will not be repeated here. Figure 18 This is a simplified cross-sectional view of the structure of the smart switch 100. Figure 18 The document contains two diagrams. The first diagram shows the structure of the base shell 3 before deformation, and the second diagram shows the structure of the base shell 3 after deformation. As can be seen, when the base shell 3 deforms towards the wall, the deformation caused by the mounting screws 32 has a minimal impact on the panel base 1 because the left and right ends of the panel base 1 are connected to the base shell 3, and the mounting screws 32 are located on the sides of the base shell 3 that are not connected to the panel base 1. Furthermore, the left and right ends of the base shell 3 abut against the wall, further reducing the impact of the deformation on the panel base 1. Since each circuit board 5 is connected to the panel base 1 and not directly to the base shell 3, the deformation of the base shell 3 has a very small impact on the circuit boards 5, thus preventing damage to the circuit boards 5.

[0159] Furthermore, there is only one circuit board 5. The circuit board 5 is connected to external wires and is equipped with both high-voltage and low-voltage circuits. The circuit board 5 includes a relay 40, a power supply circuit 50, and a detection element 52. The power supply circuit 50 is electrically connected to the external wires and converts AC power to DC power. The detection element 52 is used for detection and control. The relay 40 is electrically connected to the detection element 52 and can switch its on / off state in response to the detection element 52 being controlled. The control can be either a press control or a touch control. When the control is a press control, the detection element 52 can be a detection switch, tactile switch, micro switch, membrane switch, Hall effect sensor, etc., and can be triggered in response to the press control. When the control is a touch control, the detection element 52 can be a capacitive touch sensing module, etc., and can be triggered in response to the touch control. The technical details of the detection element 52, relay 40, and power supply circuit 50 have been described in detail above and will not be repeated here. This invention integrates high-voltage and low-voltage circuits onto a single circuit board 5, saving space in the base shell 3 and making it smaller. This allows the base shell 3 to be placed more conveniently in the junction box, improving the ease of installation of the smart switch 100. At the same time, it also leaves more space in the junction box to accommodate other structures, such as wiring harnesses.

[0160] Existing smart switches typically have a high-voltage circuit board fixedly connected to a base. When installed on a wall, the base is prone to deformation towards the wall's interior, causing the high-voltage circuit board to move inwards. In this invention, the high-voltage and low-voltage circuits are concentrated on the same circuit board, and the detection element is also located on this board. If the circuit board moves inwards towards the wall, the gap between the button and the detection element will increase, potentially causing the button to fail to trigger the detection element. To solve this problem, according to an embodiment of the invention, such as... Figure 6 and Figure 9 As shown, the smart switch 100 also includes a button 21, which abuts against the detection element 52 for receiving press operation and triggering the detection element 52 in response to the press operation. The button 21 is connected to the panel base 1 so that when the bottom shell 3 deforms, the relative positional relationship between the circuit board 5 and the button 21 is not significantly affected, thus allowing the button 21 to trigger the detection element 52 even when the bottom shell 3 deforms. The connection structure 25 between the button 21 and the panel base 1 has been described in detail above and will not be repeated here. The detection element 52 is preferably a tactile switch.

[0161] According to an embodiment of the present invention, the bottom shell 3 does not provide direct fixing constraints to the circuit board 5, so as to further reduce the impact of deformation of the bottom shell 3 on the circuit board 5.

[0162] According to embodiments of the present invention, such as Figure 13 and Figure 9As shown, the panel base 1 and the bottom shell 3 are detachably connected, so that when the panel base 1 is detached from the bottom shell 3, each circuit board 5 is also detached from the bottom shell 3. Therefore, during assembly, only the circuit board 5 needs to be fixed to the panel base 1, and the bottom shell 3 can be quickly and easily snapped onto the panel base 1 to complete the assembly, improving assembly efficiency. Furthermore, the panel base 1 and the bottom shell 3 form a receiving cavity, and the circuit board 5 is housed within this cavity. The circuit board 5 carries both high-voltage and low-voltage circuits. The panel base 1 includes a detachment structure 16 for separating the panel base 1 from the bottom shell 3. The detachment structure 16 is located on the back of the panel base 1, so that when the smart switch 100 is installed on a wall, the detachment structure 16 is hidden between the panel base 1 and the wall. Because the present invention places the high-voltage and low-voltage circuits on the same circuit board 5, the circuit board 5 cannot be exposed to the outside to prevent electric shock. Therefore, the circuit board 5 of the present invention is enclosed between the panel base 1 and the bottom shell 3, and the panel base 1 does not need to be removed when installing the smart switch 100. Since the disassembly structure 16 is hidden between the panel base 1 and the wall, the user cannot remove the panel base 1, thus avoiding the risk of electric shock caused by the user accidentally removing the panel base 1 and exposing the circuit board 5. The technical details of the panel base 1, the bottom shell 3, and the disassembly structure 16 have been described in detail above and will not be repeated here.

[0163] In one exemplary embodiment, such as Figure 15 and Figure 17 As shown, the disassembly structure 16 includes a second buckle 161, and the bottom shell 3 is provided with a second snap-fit ​​position 33 adapted to the second buckle 161. The second buckle 161 is fastened to the second snap-fit ​​position 33, and the second buckle 161 can be pried to allow the panel base 1 to be detached from the bottom shell 3. The second buckle 161 is integrally formed on the inner side wall of the panel base 1, and the second snap-fit ​​position 33 is provided on the side of the bottom shell 3 away from the panel base 1, so that when the smart switch 100 is installed on the wall, the second buckle 161 is hidden between the panel base 1 and the wall.

[0164] In another exemplary embodiment, such as Figure 19As shown, the disassembly structure 16 includes a connecting screw 162. The left end of the panel base 1 is fastened to the bottom shell 3, and the right end is provided with a threaded connection hole adapted to the connecting screw 162. The bottom shell 3 is provided with a countersunk hole adapted to the threaded connection hole. The connecting screw 162 passes through the countersunk hole and connects to the threaded connection hole to achieve a detachable connection between the panel base 1 and the bottom shell 3. The countersunk hole is provided on the side of the bottom shell 3 that is in contact with the wall, and the countersunk hole can accommodate the nut of the connecting screw 162. When the smart switch 100 is installed on the wall, the connecting screw 162 is hidden between the panel base 1 and the wall.

[0165] According to embodiments of the present invention, such as Figure 15 and Figure 18 As shown, the circuit board 5 is fixedly connected to the panel substrate 1 by a plurality of fixing screws 554. The bottom shell 3 is provided with a relief recess 35 at the corresponding position of the fixing screws 554. The relief recess 35 is used to accommodate the nuts of the fixing screws 554, so that the circuit board 5 can be close to the bottom shell 3, thereby reducing the thickness of the panel substrate. The technical details of the relief recess 35 have been described in detail above and will not be repeated here.

[0166] According to embodiments of the present invention, such as Figure 15 and Figure 16 As shown, a wireless communication module 56 is provided on the side of the circuit board 5 facing away from the panel substrate 1. No copper foil is laid on the circuit board 5 at the position corresponding to the wireless communication module 56, so that the wireless signal can pass through the circuit board 5 and the circuit board 5 can avoid shielding the wireless signal.

[0167] Since the circuit board 5 of this invention carries a high-voltage circuit, there is a certain probability that the high voltage on the circuit board 5 will be transmitted to the mounting screw 32 along the surface of the insulating material. Therefore, sufficient creepage distance needs to be designed to prevent current leakage from the circuit board 5 to the mounting screw 32. Creepage distance is the shortest spatial distance measured along the surface of the insulating material between two conductive components. According to an embodiment of the present invention, as... Figure 15 and Figure 13 As shown, the mounting hole 31 is used to insert the mounting screw 32, and the bottom shell 3 is mounted externally through the mounting screw 32; the bottom shell 3 has an isolation wall 36 protruding around the mounting hole 31 towards the panel base 1, and the circuit board 5 is arranged on the outside of the isolation wall 36. The isolation wall 36 surrounds the mounting hole 31, and the current on the circuit board 5 needs to cross the isolation wall 36 to reach the mounting screw 32, thereby increasing the creepage distance between the circuit board 5 and the mounting screw 32 and preventing the user from touching the mounting screw 32 and getting an electric shock.

[0168] With the development of the Internet of Things (IoT), the functions of smart switches 100 are becoming increasingly diversified, and their functions may even change. Consequently, traditional smart switches with fixed button functions are gradually failing to meet user needs. As the functions of smart switches 100 become more diverse, the functions of each button may also change according to user requirements. Therefore, please refer to [link / reference needed]. Figure 25 This document provides a block diagram of a smart switch 100 according to an embodiment of the present invention. As can be seen, the smart switch 100 includes at least a display device 10, a processing device 30, and an infrared detection device 20. The processing device 30 detects external objects through the infrared detection device 20 and controls the display device 10 based on the detection results. The content displayed on the display device 10 can be customized according to user needs. External detection can be understood as detecting whether anyone is approaching within a designated detection area based on the smart switch 100.

[0169] Understandably, smart switches 100, such as wall-mounted push-button switches, touchscreen switches, and touch switches, are generally placed in locations easily accessible to human hands. Therefore, the operating environment for smart switches 100 is relatively complex. Since infrared detection technology relies on the active transmission and reception of infrared waves for external detection, any object reflecting these waves could trigger the detection of approaching persons. Consequently, the industry generally believes that infrared detection technology is unsuitable for the complex usage scenarios of smart switches 100. This has resulted in infrared detection technology not being applied to wall-mounted push-button switches, touchscreen switches, and touch switches 100. Instead, other proximity sensing technologies with strong anti-interference capabilities, such as infrared pyroelectric and microwave radar, have been used. However, infrared pyroelectric requires a Fresnel lens, affecting the overall appearance and structure of the smart switch 100, while microwave radar is expensive. For some low-cost smart switches 100, controlling manufacturing costs is difficult, hindering their large-scale market application.

[0170] Based on this, this embodiment provides a smart switch 100 that uses infrared detection technology for proximity sensing, and the proximity sensing distance can be freely defined by the user to reduce interference caused by the complexity of the smart switch 100. This embodiment focuses on the hardware and software aspects of the smart switch 100, and its corresponding structural solution is applicable to the above-mentioned... Figures 1 to 24 The smart switch 100 described in any embodiment. Furthermore, the embodiments corresponding to the software and / or hardware solutions of the smart switch 100 provided in this embodiment can be compared with those described above. Figures 1 to 24 The structural scheme of the smart switch 100 described in any of the embodiments is combined.

[0171] Specifically, the display device 10 has at least two operating states;

[0172] The infrared detection device 20 is used to emit detection waves outward to form a designated detection area, and includes multiple selectable drive circuits 2011 for driving the outward emission of the detection waves; wherein the drive resistance of each drive circuit 2011 is different (e.g., Figure 26 As shown in the figure, this makes the range of the designated detection area corresponding to each drive circuit 2011 different;

[0173] The processing device 30 is connected to the display device 10 and the infrared detection device 20 respectively. It is used to acquire the detection result of the infrared detection device 20 and switch the working state of the display device 10 according to the detection result. The processing device 30 can change the selected driving circuit 2011.

[0174] The operating state of the display device 10 can be understood as the display device 10 turning on the screen, turning off the screen, etc. Furthermore, the at least two operating states of the display device 10 are different from each other, and include at least a lit state (screen-on state) and a turned-off state (screen-off state). The range of the designated detection area can be understood as the range that the detection wave can reach and be reflected. The processing device 30 can select at most one driving circuit 2011 at any given time, so that the range of the designated detection area is selectively specified.

[0175] In a specific example, the processing device 30 detects the current state of the smart switch 100 through the infrared detection device 20. The current state indicates whether someone is approaching a designated detection area of ​​the smart switch 100. The display device 10 is controlled by the processing device 30 to switch between an on state and an off state. The multiple drive circuits 2011 are connected to the same power supply. The drive resistor is used to limit the drive capability of the selected drive circuit 2011. With a fixed power supply, the larger the drive resistor, the smaller the current of the corresponding drive circuit 2011, that is, the weaker the drive capability and the shorter the detection distance. The smaller the drive resistor, the larger the current of the corresponding drive circuit 2011, that is, the stronger the drive capability and the longer the detection distance. It is understood that the infrared detection device 20 detects external objects based on infrared waveband detection. Therefore, any object that can reflect the detection wave may trigger the infrared detection device 20. Thus, the "person" in "someone is approaching" described in this embodiment should be interpreted broadly, that is, any person, animal, or other object that can reflect the detection wave and trigger the infrared detection device 20.

[0176] Furthermore, based on the above solution, the smart switch 100 provided in this embodiment overcomes the industry's common misconception that infrared detection technology is unsuitable for application scenarios of smart switches 100. It adopts a low-cost infrared detection device 20 for proximity sensing detection, and uses multiple drive circuits 2011 with different drive resistors to selectively drive the infrared detection device 20. As a result, the detection distance can change with the selected drive circuit 2011, so that the smart switch 100 has the ability to adjust the detection distance. Users can adjust the detection distance according to the actual applicable environment of the smart switch 100 to improve interference problems.

[0177] Furthermore, to differentiate the detection distances of the two drive circuits 2011 as much as possible, the resistance difference between any two drive circuits 2011 is set to be greater than 10Ω. This ensures that the change in detection distance is clearly distinguishable when switching between any two drive circuits 2011. In actual testing, when the resistance difference between the two drive circuits 2011 is set to 10Ω, the detection distance can be differentiated by at least 5cm for some models of infrared LEDs 2012.

[0178] Furthermore, in order to facilitate users to freely set the proximity sensing distance of the smart switch 100, the processing device 30 is also used to receive an external selection signal, which is used to switch the selected drive circuit 2011.

[0179] Specifically, users can send the selection signal through a smart terminal. For example, after configuring the smart switch 100 to the network, the user establishes a communication relationship with the smart switch 100 through a mobile phone, and then adjusts the detection distance through the operation interface of the application (app) corresponding to the smart switch 100 installed on the mobile phone (e.g., Figure 27 As shown in the figure, the application then sends the corresponding selection signal directly or indirectly to the smart switch 100 to adjust the detection distance.

[0180] In conjunction with the above embodiment where the resistance difference between any two drive circuits 2011 is greater than 10Ω, when the user switches between the drive circuits 2011 of the smart switch 100 via a smart terminal, a clear distinction in the detection distance can be formed, so that the change in detection distance can be intuitively felt by the user with each switch of a drive circuit 2011, so that the user can adjust the detection distance according to actual needs.

[0181] Further, the selection signal includes a first selection signal, a second selection signal, and a third selection signal; wherein the processing device 30 can turn off the infrared detection device 20 according to the first selection signal, the processing device 30 can select the first driving circuit 20111 in the multiplexing driving circuit 2011 according to the second selection signal, and the processing device 30 can select the second driving circuit 20112 in the multiplexing driving circuit 2011 according to the third selection signal.

[0182] The first selection signal is generated when the first of a plurality of preset distance levels on the smart terminal is selected; the second selection signal is generated when the second of the plurality of levels is selected; and the third selection signal is generated when the third of the plurality of levels is selected (e.g., ...). Figure 27 (As shown).

[0183] Therefore, the first, second, and third gears respectively form three detection distance adjustment gears for the smart switch 100. In the first gear, the infrared detection device 20 is turned off, that is, the detection distance of the smart switch 100 is 0. The second and third gears represent two different detection distances. Users can conveniently switch between the first and third gears through the smart terminal to freely select the detection distance of the smart switch 100.

[0184] Furthermore, the resistance difference between the driving resistor of the first driving circuit 20111 and the driving resistor of the second driving circuit 20112 is greater than or equal to 50Ω, so that there is at least a distance difference of 20cm between the second gear and the third gear.

[0185] In a specific example, such as Figure 28 As shown, a 47Ω driving resistor is connected in series with the first driving circuit 20111, and a 100Ω driving resistor is connected in series with the second driving circuit 2012, so that when the first driving circuit 20111 is selected, there is a detection distance A, and when the second driving circuit 20112 is selected, there is a detection distance B. The value of A ranges from 80cm to 100cm, and the value of B ranges from 30cm to 50cm. In this example, the difference between the driving resistor of the first driving circuit 20111 and the driving resistor of the second driving circuit 20112 is 53Ω, allowing a distance difference of more than 50cm to be formed between the second and third gear positions.

[0186] It should be noted that the detection distance of 80cm to 100cm can be understood as a detection distance formed by a certain point or segment within the range of 80cm to 100cm. For example, when the detection distance is 80cm, the designated detection area formed by the smart switch 100 in the second position will cover the detection distance of 0cm to 80cm. When someone is about 80cm away from the front of the smart switch 100, the display device will be triggered to light up the screen. When the detection distance is in the range of 80cm to 90cm, the designated detection area formed by the smart switch 100 in the second position will cover the nearest detection distance of 0cm and the farthest detection distance of [80cm, 90cm]. In this case, the farthest detection distance in the second position fluctuates within a range and is not a fixed value. Similarly, the 30cm to 50cm range can also be understood in this way. When the detection distance is 30cm, when someone is about 30cm away from the front of the smart switch 100, the display device will be triggered to light up the screen.

[0187] In one possible usage scenario, the smart switch 100 is installed in the entryway. It's understood that entryways are typically around 100cm wide, and in some smaller apartments, the entryway width may be even narrower. Furthermore, the actual space in the entryway may be further reduced due to the accumulation of items, shoe cabinets, or wardrobes. If the detection distance of the smart switch 100 is uncontrolled, the emitted detection wave may be directly reflected by objects or walls opposite the smart switch 100, causing the infrared detection device 20 to remain in an triggered state, rendering the proximity sensor ineffective. In this usage scenario, based on the solution of this embodiment, the user can switch the proximity sensor of the smart switch 100 to the third level to shorten the maximum detection distance. This ensures that the designated detection area does not cover the wall or objects opposite the smart switch 100; that is, the detection wave's distance is limited and cannot reach the opposite wall. However, when a person passes through the entryway, the detection wave can be reflected back, triggering the infrared detection device 20, thus effectively avoiding interference.

[0188] In another possible use case, the smart switch 100 is installed in the living room, where the surrounding area is relatively open. In this case, in order to improve the screen sensitivity of the smart switch 100, the user can set the smart switch 100 to the second level. As a result, the user can trigger the smart switch 100 from a greater distance, thus improving the user experience.

[0189] The installation environment of the smart switch 100 differs in the two usage scenarios described above, resulting in different required proximity sensing detection distances. The solution provided in this embodiment enables the smart switch 100 to freely switch the detection distance based on the user's actual needs, increasing the applicability and flexibility of infrared detection technology in the usage scenarios of products like the smart switch 100.

[0190] In some embodiments, such as Figure 29 As shown, the infrared detection device 20 includes an infrared emitting unit 201 and an infrared receiving unit 202, and the processing device 30 is used to transmit signals through two different driving signals (e.g., infrared emitting unit 201 and infrared receiving unit 202). Figure 29 The encoded signal and carrier signal in the infrared transmitter 201 drive the selected driving circuit 2011 in the infrared transmitter 201 to synthesize the detection wave with unique signal characteristics, so that the infrared receiver 202 can identify the detection wave according to the unique signal characteristics.

[0191] Furthermore, if the detection wave received by the infrared receiving unit 202 does not conform to the unique signal characteristics, it will not respond, so as to filter infrared waves of other encoding forms and prevent interference from infrared waves emitted by devices such as air conditioner remote controls and television remote controls.

[0192] The structural location and implementation of the infrared detection device 20 in the smart switch 100 can be referred to as follows: Figure 11 , Figure 6 and Figure 20 The description of the illustrations and their corresponding embodiments is for your understanding.

[0193] Furthermore, such as Figure 30 As shown, the infrared emitting unit 201 includes:

[0194] The feature synthesis circuit 2013 is electrically connected to the processing device 30 and can be controlled by a drive signal of the processing device 30 to switch on and off states according to a preset rule.

[0195] An infrared LED 2012 is connected in series with the feature synthesis circuit 2013 and each driving circuit 2011 so that it is driven by the selected driving circuit 2011 to emit infrared light when the feature synthesis circuit 2013 is turned on.

[0196] The driving circuit 2011 is driven by another driving signal from the processing device 30, which may be, for example, a 38kHz PWM signal output from the PWM port as described in a later embodiment. Based on both the driving signal and the other driving signal, the feature synthesis circuit 2023 and the driving circuit 2011 jointly drive the infrared LED 2012 to synthesize a detection wave with the specific signal characteristics.

[0197] Specifically, such as Figure 31 As shown, a specific implementation circuit is given, which can be seen as follows:

[0198] The driving circuit 2011 has two paths: a first driving circuit 20111 composed of transistor Q11 and a second driving circuit 20112 composed of transistor Q7. The driving resistor of the first driving circuit 20111 is R93 with a value of 47Ω, and the driving resistor of the second driving circuit 20112 is R88 with a value of 100Ω. The feature synthesis circuit 2013 includes an electronic switch formed by MOSFET Q8. The infrared LED1 is connected in series between Q8 and each driving circuit 2011. The electronic switch can be controlled to be turned on or off by the processing device 30. When the electronic switch is turned on, the infrared LED1 is powered on, and when the electronic switch is turned off, the infrared LED12 is de-powered.

[0199] Specifically, the first driving circuit 20111 consists of Q11, resistors R93, R91 and R92. The collector of Q11 is electrically connected to the cathode of LED1 through R93, the emitter of Q11 is grounded, and the base of Q11 is electrically connected to the processing device 30 as a controlled terminal through R91 so that it can be switched between on and off under the control of the processing device 30. R92 is electrically connected between the base and emitter of Q11. In addition, one end of R91 connected to the processing device 30 is also grounded through a Zener diode D30 to form a voltage regulation protection function.

[0200] The second driving circuit 20112 consists of Q7, resistors R88, R82 and R14. The collector of Q7 is electrically connected to the cathode of LED1 through R88, the emitter of Q7 is grounded, and the base of Q7 is electrically connected to the processing device 30 through R82 as the controlled terminal so that it can be switched between on and off under the control of the processing device 30. R14 is electrically connected between the base and emitter of Q7. In addition, one end of R82 connected to the processing device 30 is also grounded through a Zener diode D29 to form a voltage regulation protection function.

[0201] Q8 is a PMOS transistor. Its source (S) is connected to the power supply (3.3V), its drain (D) is connected to the anode of LED1, and its gate (G) is connected to the processing device 30 via a current-limiting resistor R85 to switch between on and off under the control of the processing device 30. Furthermore, Q8's gate is equipped with a pull-up resistor R84, and a voltage regulator C15 is also provided at the power supply location.

[0202] When the driving resistor is 100Ω, the actual operating current is (3.3V-1.3V) / 100Ω=20mA. At this time, the loss in the resistor is 0.04W, and the emission power of LED1 is 1.3V×20mA=26mW.

[0203] When the current-limiting resistor is 47Ω, the actual operating current is (3.3V-1.3V) / 47Ω≈42.6mA. At this time, the loss in the resistor is 0.08W, and the emission power of LED1 is 1.3V×42.6mA=55.38mW.

[0204] like Figure 31 As shown, the infrared LED1 can specifically be a surface-mount infrared LED of Xinyongcheng, model XYC-IRA4335A65-X4. It is a low-power diode with a 4335 package, which has the advantages of strong emission power and uniform light reception angle. Its emission wavelength is 940nm, the maximum continuous operating current is 100mA, and the maximum power consumption is 150mW.

[0205] Furthermore, the emission angle of the infrared LED1 is limited to: [63°, 73°] on the X-axis and [22°, 28°] on the Y-axis. For example, a surface-mount infrared LED of model XYC-IRA4335A65-X4 can be used, which has an emission angle of 66 degrees on the X-axis (±33 degrees) and 25 degrees on the Y-axis. The eccentricity angle is a maximum of +5 degrees and a minimum of -5 degrees on both the X-axis and Y-axis.

[0206] Furthermore, the larger lateral emission angle (X-axis emission angle) makes the infrared LED suitable for use scenarios where the smart switch 100 requires a large lateral detection range.

[0207] Furthermore, the driving signal includes a carrier signal and an encoded signal, wherein the processing device 30 selects a driving circuit 2011 through the carrier signal and drives the feature synthesis circuit 2013 to switch on and off through the encoded signal, so as to synthesize the detection wave with unique signal characteristics emitted by the infrared light-emitting tube 2012.

[0208] For specific examples, such as Figure 31 As shown, the processing device 30 outputs a 38kHz PWM signal (IR_PWM1 and IR_PWM2) through the PWM port as the carrier signal, and outputs a predetermined encoding sequence through the serial port to form an encoded signal (IR_TX) with the unique signal characteristics.

[0209] like Figure 31 The operation of the circuit shown can be understood as follows: When the first driving circuit 20111 is selected, the processing device 30 outputs a 38kHz PWM signal through IR_PWM1 to drive the switching of Q11, and simultaneously outputs an encoded signal IR_TX through the serial port to drive Q8 to open and close regularly according to a predetermined encoded sequence, so that LED1 can achieve infrared light encoded output and emit an infrared detection wave that conforms to the specific signal characteristics. Similarly, the operation of the second driving circuit 20112 can be understood in the same way.

[0210] Furthermore, this embodiment provides a scheme for simulating the transmission of detection waves via a serial port and PWM interface, enabling some processing devices 30 that do not support simultaneous transmission and reception (such as the Xiaomi MHCB05P-B module involved in subsequent embodiments) to also use it. In other words, the processing device 30 generally uses a microcontroller or module. Some microcontrollers, in order to reduce size and save hardware costs, do not support simultaneous transmission and reception of infrared detection waves. The scheme provided in this embodiment allows such processing devices 30 to simulate the transmission of detection waves via a serial port and PWM interface. Therefore, by simply sending a predetermined encoded sequence into the serial port, an encoded detection wave can be simulated, allowing the processing device 30 to achieve infrared detection by simulating the transmission of an infrared band detection wave and receiving that detection wave, even when simultaneous transmission and reception are not supported. Moreover, controlling the timing corresponding to the predetermined encoded sequence via the serial port has better timing stability than software control via I / O ports, resulting in a more stable transmitted detection wave and ensuring detection stability.

[0211] Furthermore, such as Figure 32 As shown, the unique signal features are specifically defined as an interconnected identification area, a data area, and a verification area. The identification area is used by the infrared receiving unit 202 to identify whether the detection wave is valid, and the data area and the verification area are used by the infrared receiving unit 202 to identify whether the detection wave is legitimate.

[0212] In a specific example, bit 1 is defined as a 500µs high level followed by a 1500µs low level, and bit 0 is defined as a 500µs high level followed by a 500µs low level. The identification area is defined as a 5000µs high level followed by a 2500µs low level. The data area consists of bit 1 and bit 0 alternating 16 times, and the verification area consists of a 500µs high level followed by an intermittent low level. During operation: the infrared receiving unit 202 determines that the received detection wave is valid when it has a continuous 5000µs high level and a 2500µs low level. Only after receiving 16 alternating waveforms corresponding to bit 1 and bit 0, along with a 500µs high level and intermittent low levels, does it consider the detection wave valid and output a trigger signal to activate the processing device 30.

[0213] based on Figure 32 The detection wave, encoded in the predetermined format shown, can filter out some naturally generated random infrared waves through the identification area to improve anti-interference capability. It can also filter infrared waves sent by devices such as air conditioner remote controls and TV remote controls that are arranged according to certain rules through the data area and verification area. The addition of the verification area can improve security, reduce the risk of being cracked, and enhance security.

[0214] In some embodiments, the processing device 30 is further configured to control the infrared emitting unit 201 of the infrared detection device 20 to operate in a periodically alternating emission state and a pause state. In the emission state, the infrared emitting unit 201 emits the detection wave to the outside, and in the pause state, the infrared emitting unit 201 stops emitting the detection wave.

[0215] Therefore, in this embodiment, in order to reduce the burden on the processing device 30, the infrared emitting unit 201 of the infrared detection device 20 is not in a continuous emitting state, but alternately switches between the emitting state and the pause state. In the pause state, the infrared emitting unit 201 of the infrared detection device 20 is in a rest mode and does not emit detection waves to the outside, so as to reduce the load on the processing device 30.

[0216] In addition, in order to ensure that the detection capability of the infrared detection device 20 is stable before and after the display device 10 is lit, in this embodiment, the duration of the emission state is set to be the same before and after the display device 10 is lit, and the difference in the duration of the pause state is less than or equal to 100ms.

[0217] Furthermore, this embodiment ensures the stability of the duration of the emission state of the infrared emitting unit 201 and allows the duration of the pause state of the infrared emitting unit 201 to fluctuate within a certain range. In other words, if the duration of each emission state of the infrared emitting unit 201 before the display device 10 is lit is defined as a first time, and the duration of each emission state of the infrared emitting unit 201 after the display device 10 is lit is defined as a second time, then in this embodiment, the first time and the second time are set to be the same. If the duration of each pause state of the infrared emitting unit 201 before the display device 10 is lit is defined as a third time, and the duration of each pause state of the infrared emitting unit 201 after the display device 10 is lit is defined as a fourth time, then in this embodiment, the difference between the third time and the fourth time is set to be less than or equal to 100ms. Experimental verification shows that fluctuations in the difference between the third time and the fourth time within the range of 100ms do not significantly affect the detection performance of the infrared detection device 20.

[0218] Furthermore, before the display device 10 is turned on, the ratio of the duration of the emission state to the working cycle is set to be greater than or equal to 10%. The working cycle is the sum of the duration of the emission state and the duration of the pause state.

[0219] In one example, before the display device 10 is turned on, the duration of the transmission state is set to approximately 56 ms, while the duration of a complete working cycle of a transmission state and a pause time is set to 100 ms.

[0220] In another example, before the display device 10 is turned on, the duration of the emission state is set to about 56ms, and the total working cycle of one emission state and pause time is set to 200ms.

[0221] In general, when the ratio of the duration of the emission state to the working cycle is set to be greater than or equal to 10%, the working cycle consisting of the sum of the duration of the emission state and the duration of the pause state is set between 10ms and 100ms or between 100ms and 200ms, which can reduce the workload of the processing device 30 to a certain extent while achieving good infrared detection effect.

[0222] In a further example, the duration of the pause state is set to be the same before and after the display device 10 is turned on. In other words, the operating state of the infrared emitting unit 201 remains unchanged before and after the display device 10 is turned on, so as to ensure the stability of infrared detection performance.

[0223] In another variation, after the display device 10 is turned on, the duration of the pause state is increased by 100ms compared to before the display device 10 is turned on. This is so that after the display device 10 is turned on, the infrared emitting unit 201 emits detection waves at a lower frequency. After the display device 10 is turned off, the frequency of the infrared emitting unit 201 emitting detection waves is restored, thus not affecting the sensitivity and response speed of the human proximity sensing in the screen-off state. Furthermore, the frequency reduction during the period when the display device 10 is turned on can further reduce the workload of the processing device 30.

[0224] In some embodiments, such as Figure 33 As shown, the intelligent switch 100 also includes relays 40. The processing device 30 drives the switching of each relay 40 through a relay drive circuit 80. Each relay 40 controls a target circuit that supplies power to an electrical device 200. When a relay 40 is connected, the electrical device 200 connected to its controlled target circuit is powered; when a relay 40 is disconnected, the electrical device 200 connected to its target circuit is de-energized. Each relay 40 forms a control channel, and multiple relays 40 can form multiple control channels. The switching of the relays 40 between on and off corresponds to the switching of the power supply / power-off operating state of the corresponding control channel.

[0225] An exemplary embodiment of the structural location of the relay 40 in the smart switch 100 can be found in the above embodiments, such as... Figure 15 and Figure 16 The description of the illustrated embodiments is for understanding purposes only.

[0226] In this embodiment, as Figure 34 The diagram shows the circuit schematic of a relay drive circuit 80, and its working principle is as follows:

[0227] The processing device 30 outputs a drive signal via RELAY. When the control signal RELAY from the relay 40 is high, the collector and emitter of the transistor Q4 are turned on. The 5V power supply flows through the coil of the relay 40 and then through the transistor to GND (ground). The contacts of the relay 40 are energized, connecting L (live wire) and L_OUT (target circuit control line). L_OUT outputs voltage, and the target circuit is powered on. It should be noted that when there are multiple control channels, the processing device 30 controls the relays 40 corresponding to each control channel through multiple control ports. For example, in a subsequent embodiment, RELAY-1, RELAY-2, and RELAY-3 are electrically connected to the processing device 30, and the processing device 30 controls the three relays 40 through RELAY-1, RELAY-2, and RELAY-3 respectively.

[0228] When the control signal RELAY of relay 40 is low, the collector and emitter of transistor Q4 are not conducting, no current flows through the coil of relay 40, the contacts of relay 40 do not close, L and L_OUT are not connected, L_OUT has no voltage output, and the target circuit is disconnected from the power supply.

[0229] When the control signal RELAY of relay 40 switches from high level to low level, the coil current of relay 40 will not change abruptly, so a reverse electromotive force will be generated. In order to avoid damage to other components, D5 acts as a freewheeling diode to release the energy path of the coil.

[0230] like Figure 33As shown, the intelligent switch 100 also includes a power supply circuit 50 and a zero-crossing detection circuit 60. The power supply circuit 50 includes a first power conversion circuit 501, a second power conversion circuit 502, and a third power conversion circuit 503. The first power conversion circuit 501 rectifies and converts the mains AC power (e.g., 220V, 50Hz) into a first power source. The second and third power conversion circuits 502 and 503 are electrically connected to the first power source to convert it into a second and a third power source with different voltages. The first power source powers the relay 40 (e.g., 5V), the second power source powers the processing module (e.g., 3.3V), and the second and third power sources power the display device 10. The rectified power from the first power conversion circuit 501 is also supplied to the zero-crossing detection circuit 60 for detecting the zero-crossing point of the mains AC power, ensuring that the relay 40 operates near the zero-crossing point of the AC power, reducing surge voltage and extending service life.

[0231] For specific examples, such as Figure 35 As shown, the processing device 30 can use the MHCB05P-B module from Xiaomi Corporation, and the display screen of the display device 10 can be an OLED display. In this embodiment, the OLED screen requires two power supply voltages: 3.3V and 3.7-4.2V. The first power conversion circuit 501 can use a power conversion circuit based on a PN8016SSC-R1B switching power supply to convert 220V AC power to a 5V first power output. The second power conversion circuit 502 can use an LDO power conversion circuit based on a BL1117-33CX to convert the 5V first power to a 3.3V second power output. This 3.3V power is used to power the MHCB05P-B module and the OLED display. The third power conversion circuit 503 can use an LDO power conversion circuit based on a ME6209A40PG from Weimob. The ME6209A40PG has a maximum input voltage of 18V, a fixed output voltage of 4V, a maximum output current of 250mA, and uses an SOT89-3 package. Its power dissipation is 500mW, and it features a low dropout voltage. A third 4V power supply powers the LEDs of the OLED display, with a maximum power consumption of 65.86mW × 3 = 197.58mW and a maximum current of 49.395mA. The ME6209A40PG meets these power requirements.

[0232] like Figure 36As shown, the zero-crossing detection circuit 60 includes a detection circuit centered around transistor Q5. Specifically, Q5 is an NPN transistor, with its collector connected to a second power supply via resistor R76, its base connected to AC power via three 100KΩ resistors R30, R31, and R32, and its emitter grounded. A resistor R77 and a capacitor C84 are connected in parallel between the emitter and base. The collector of Q5 outputs a zero-crossing detection signal to the processing module via pin ZVD. The working principle is roughly described below:

[0233] When the voltage difference between the live wire (L) and neutral wire (N) of the power frequency AC current is large, the collector and emitter of transistor Q5 conduct, and ZVD outputs a low level. When the voltage difference between L and N is small, the collector and emitter of transistor Q5 do not conduct, and ZVD outputs a high level. The waveform of ZVD is a 100Hz square wave. The midpoint between the high and low levels of the square wave is the zero-crossing moment. The MHCB05P-B module controls the relay 40 to engage / disengage based on this zero-crossing moment to reduce the surge voltage during operation.

[0234] In some embodiments, such as Figure 33 and Figure 35 As shown, the smart switch 100 also includes buttons, and the display device 10 includes a display screen corresponding to the buttons.

[0235] Among them, such as Figures 1-5 As shown, in its specific structure, the display screen is located at one end near the button and is divided into multiple display areas along the extension direction of the button (e.g., Figure 37 As shown in the diagram, the display area away from the button is set to a non-display area, the display area close to the button is set to a channel indicator area to display the working status of the control channel to which the button is located, and part or all of the display area between the non-display area and the channel indicator area is set to a button identification area to display the button information of the corresponding button; the processing device 30 is further configured to, when detecting a change in the working status of the control channel corresponding to the button, change the display content of the channel indicator area to indicate the current working status of the control channel corresponding to the button, while keeping the display content of the button identification area unchanged;

[0236] The display device 10 has at least two operating states, including a first state in which the button marking areas of all displays are not displayed and a second state in which the button marking areas of at least one display are displayed.

[0237] Furthermore, the smart switch 100 does not require separate indicator lights for the control channel via buttons; instead, it directly indicates the operating status of the control channel through a portion of the display area on the screen. When the operating status of the control channel changes, the channel indicator area in the multi-segment display area is partially refreshed, while the button indicator area is not refreshed, thereby reducing the overall refresh rate of the display screen and extending its lifespan.

[0238] Specifically, each button corresponds to a relay 40, and the on / off state of the relay 40 can be switched by pressing the button. In a specific example, there can be multiple buttons, each with its own display screen. These displays are separate and do not interfere with each other. Each button's display screen shows relevant information about the button (e.g., the button's function name). The specific content displayed can be customized by the user through a terminal device, and the customized content is displayed on the screen, allowing the user to freely change the indication information of each button. For example, the smart switch 100 includes three buttons, and correspondingly, three displays, each used to display the working status of the control channel corresponding to one of the three buttons. Figure 37 As shown, each display screen uses a 0.49-inch OLED display with a display area size of 11.18mm × 5.58mm and a resolution of 64 × 32. The display screen is divided into multiple display areas from top to bottom, using 4 pixels as a reference. The top 64 × 8 pixel area is a non-display area, the middle 64 × 16 pixel area is a channel indicator area, and the bottom 64 × 4 pixel area near the top is a button label area. The channel indicator area uses a 16 × 16 pixel character set, and each display screen's channel indicator area can display a maximum of 4 Chinese characters or 8 letters. The button label area displays a horizontal line; the presence or absence of the horizontal line indicates the working status of the corresponding control channel.

[0239] In some embodiments, such as Figure 35 As shown, the font library uses a hardware font library chip 70. Each display screen and the font library chip 70 communicate with the processing device 30 through the SPI bus. The processing device 30 performs SPI time-division control on the font library chip 70 and each display screen through the chip select pin.

[0240] Furthermore, the infrared receiving unit 202 includes an infrared receiving head for receiving the detection wave, such as... Figure 31 As shown, in a specific circuit, the infrared receiving unit 202 includes an infrared receiving head (such as...). Figure 11 The infrared receiver head 2021 shown here has a structural design that can be referenced. Figure 11(For understanding the description of the corresponding embodiment); at least one display screen is provided between the infrared LED 2012 and the infrared receiver head, so as to block the detection wave emitted by the infrared LED 2012 from directly reaching the infrared receiver head through the inside of the smart switch 100, thereby reducing internal interference.

[0241] Furthermore, in order to reduce the interference of the detection wave emitted by the infrared LED 2012 directly reaching the infrared receiver head through the inside of the smart switch 100, the power of the infrared LED 2012 of the infrared emitting unit 201 is set to less than 250mW.

[0242] In a specific example, the infrared LED 2012 is an infrared LED 2012 with a maximum power consumption of 150mW. That is, each driving circuit 2011 adjusts the emission power of the infrared LED 2012 within the range of 150mW to adjust the detection distance.

[0243] In a further example, the infrared receiver head can be a model XYC-RM504201, which integrates amplification and filtering circuits to achieve long-distance infrared reception and has strong anti-interference capabilities. For specific operational details, please refer to [reference needed]. Figure 31 The circuit shown will be explained in detail here.

[0244] In some embodiments, the processing device 30 is further configured to:

[0245] Receive the first index information;

[0246] The first text information is determined based on the first index information, and the first text information is displayed in the channel indicator area to indicate the button corresponding to the display screen. The first index information is generated by the user after freely defining the name of the button on the smart terminal.

[0247] For example, the smart switch 100 includes two buttons. Pressing the first button turns the living room light on or off, and pressing the second button turns the dining room light on or off. The user can define the display screen near the first button as "living room light" and the display screen near the second button as "dining room light." This allows the display to indicate the operation information corresponding to each button, making it easier for the user to distinguish their functions. The first index information is sent to the smart switch 100 by the smart terminal. This first index information is determined by the smart terminal based on user input; that is, the display content on the smart switch 100's screen can be freely configured by the user via the smart terminal.

[0248] Furthermore, users can customize the key information of each button according to their actual needs, and what is sent is the index information corresponding to the character rather than the dot matrix, which can carry more character information in a message, and is suitable for communication protocols such as Bluetooth with short code messages.

[0249] In a specific example, the font chip 70 stores a standard GB2312 font library, where the stored text information is dot matrix data. The pixels of the dot matrix data are a×b, where a∈[12, 16], b∈[12, 16], a=b, a represents the pixels of the dot matrix data in the horizontal direction, and b represents the pixels of the dot matrix data in the vertical direction. Optionally, a=16, b=16, the pixels of the dot matrix data are 16×16, that is, when the dot matrix data is displayed on the channel indicator area of ​​the display screen, the number of pixels in the horizontal direction is 16, and the number of pixels in the vertical direction is also 16.

[0250] It should also be noted that the length of bytes occupied by the dot matrix data of a Chinese character is c, where c ∈ [24, 32]. For example, when the pixel size of the dot matrix data is 12×12, the dot matrix data of a Chinese character occupies 24 bytes; and when the pixel size of the dot matrix data is 16×16, the dot matrix data of a Chinese character occupies 32 bytes. Furthermore, the pixel size of the dot matrix data is a×b, where a ∈ [12, 16] and b ∈ [12, 16]. The range of a and b ensures that the displayed content is appropriate after the dot matrix data is displayed on the channel indicator area of ​​the display screen, avoiding unclear display content due to excessively small pixels or insufficient display content on the channel indicator area due to excessively large pixels. Setting a to equal b ensures that the horizontal pixels are the same as the vertical pixels, resulting in a square shape of the Chinese character displayed on the display of the smart switch 100.

[0251] During the configuration process of the channel indicator area of ​​each button of the smart switch 100, the smart device sends the first index information of the text to be configured in the first configuration message to the smart switch 100. The processing device 30 of the smart switch 100 processes the first index information to read the corresponding dot matrix data from the character library chip 70 and displays the dot matrix data on the channel indicator area of ​​the corresponding button's display screen. It can be understood that if the smart terminal directly sends the dot matrix data of the text to be configured to the smart switch 100, when the pixel size of the dot matrix data is 12×12, the dot matrix data of one Chinese character occupies 24 bytes, meaning that configuring one Chinese character requires transmitting 24 bytes; when the pixel size of the dot matrix data is 16×16, the dot matrix data of one Chinese character occupies 32 bytes, meaning that configuring one Chinese character requires transmitting 32 bytes. If the smart terminal sends the first index information of the text to be configured to the smart switch 100, when the first index information is Unicode encoded, the Unicode encoding of one Chinese character occupies 2 to 4 bytes, meaning that configuring one Chinese character only requires transmitting 2 to 4 bytes; when the first index information is GB2312 encoded, the GB2312 encoding of one Chinese character occupies only 2 bytes, meaning that configuring one Chinese character only requires transmitting 2 bytes. Therefore, the number of bytes occupied by the index information is less than the number of bytes occupied by the dot matrix data. Thus, when transmitting index information, the number of characters of the text to be configured that can be carried in a first configuration message is greater than the number of characters of the text to be configured that can be carried in a first configuration message when transmitting dot matrix data. In this way, the smart terminal can save communication resources by sending the index information instead of the dot matrix data to the smart switch 100.

[0252] In a further example, if the smart terminal and smart switch 100 are directly connected via Bluetooth, then the first configuration message is a Bluetooth message, and a single Bluetooth message can contain a maximum of 31 bytes for data transmission. The dot matrix data of a Chinese character occupies at least 24 bytes, therefore a single first configuration message can transmit the dot matrix data of at most one Chinese character. The first index information of a Chinese character occupies 2 to 4 bytes. When the first index information occupies 2 bytes, a single first configuration message can transmit up to 15 Chinese characters; when it occupies 3 bytes, it can transmit up to 10 Chinese characters; and when it occupies 4 bytes, it can transmit up to 7 Chinese characters. In summary, a single first configuration message can configure multiple Chinese characters. Thus, by sending the index information instead of the dot matrix data to the smart switch 100 via Bluetooth messages, the smart terminal can save communication resources.

[0253] In one optional implementation, the first index information is GB2312 encoding, and the first text information is dot matrix data. That is, the character library chip 70 of the smart switch 100 stores the dot matrix data of all Chinese characters in the GB2312 encoding table, and all the dot matrix data are arranged in the order of all Chinese characters in the GB2312 encoding table.

[0254] Further, the processing device 30 determines the corresponding first text information based on the first index information and displays the first text information in the channel indication area, specifically for:

[0255] The processing device 30 calculates a storage address based on the GB2312 encoding corresponding to the first index information. This storage address is the starting address where the dot matrix data corresponding to the input Chinese character is stored in the character chip 70. Then, starting from this storage address, it reads data of a specified byte length from the character chip 70 to obtain the dot matrix data corresponding to the input Chinese character. The specified byte length is the byte length occupied by the dot matrix data of one Chinese character. Finally, the dot matrix data is sent to the corresponding display screen for display.

[0256] Furthermore, the first index information is generated after the user freely defines the name of the button on the smart terminal, for example:

[0257] The user inputs the button information corresponding to each button through the human-computer interaction interface of the smart terminal (provided by the application corresponding to the smart switch 100). The smart terminal obtains the text to be configured corresponding to each button information and obtains the first index information based on the text to be configured.

[0258] Users trigger the smart terminal by clicking the information synchronization control displayed on the human-computer interaction interface of the smart terminal, so that the smart terminal establishes a direct Bluetooth connection with the smart switch 100; wherein, the human-computer interaction interface where the information synchronization control is located and the human-computer interaction interface where the input button information is located can be the same or different human-computer interaction interfaces.

[0259] Then the first index information is sent to the smart switch 100;

[0260] The smart switch 100 processes the first index information, reads the corresponding first text information from the character library chip 70, and displays the first text information in the channel indicator area of ​​the display screen of the corresponding button. The text content represented by the first text information is consistent with the text to be configured input by the user. Thus, after the first text information is displayed in the channel indicator area, the display content of each button's display screen is also consistent with the text to be configured input by the user.

[0261] Subsequently, the processing unit 30 of the smart switch 100 stores the first index information.

[0262] In a specific embodiment, after receiving the first index information sent by the smart terminal, the smart switch 100 stores the first index information in its memory and configures the display content on the screen according to the first index information, so that the display content on the channel indicator area corresponding to each button's display is consistent with the content input by the user on the smart terminal. Thus, when the smart switch 100 is powered off and then powered on again, the smart switch 100 can update the display content of the channel indicator area of ​​each display according to the first index information stored in the memory, so that each display shows the content that the user has most recently successfully configured, without requiring the user to reconfigure.

[0263] In a specific example, the smart switch 100 is pre-configured with the display content of each screen at the factory, such as "Button 1, Button 2, Button 3, etc." When a user purchases and receives the smart switch 100, it will automatically enter the network configuration mode upon initial power-on to facilitate quick network configuration by the user. Before the user changes the button names (i.e., the display content of each button's screen) via their mobile phone, the preset display content will be displayed on each screen by default. After the user configures the smart switch 100 via their mobile phone, they can modify the button names of each button through the app interface on their mobile phone. The modified button names are then sent to the smart switch 100 via a synchronized button name trigger operation, so that the modified button name information is displayed on each screen of the smart switch 100.

[0264] Furthermore, existing multi-channel smart switches all support the simultaneous operation of multiple control channels. For example, a three-channel smart switch can control three lights respectively, meaning all three control channels can be turned on simultaneously, activating all three lights at the same time. However, for electrical appliances with multiple speed settings, such as air purifiers and electric fans, existing smart switches lack a good solution to accommodate the switching between multiple speed settings of the same appliance. This hinders the application and promotion of smart switches for such appliances, requiring users to purchase dedicated controllers separately, causing inconvenience.

[0265] Based on this, one embodiment of the present invention proposes a smart switch. This smart switch has a first mode, enabling it to lock multiple operating zones into a single trigger state when in the first mode, thus accommodating single-mode switching applications between multiple gear positions of the same electrical device. The smart switch 100 provided in this embodiment focuses on hardware and software aspects, and its corresponding structural scheme is applicable to the above-mentioned... Figures 1 to 37 The smart switch 100 described in any embodiment. Furthermore, the embodiments corresponding to the software and / or hardware solutions of the smart switch 100 provided in this embodiment can be compared with those described above. Figures 1 to 24The structural scheme of the smart switch 100 described in any of the embodiments described, and as follows Figures 25-37 The recorded smart switch 100 is combined.

[0266] See Figure 38 As shown, an embodiment of the present invention provides an intelligent switch comprising at least a processing device 30 and at least two switching devices 90. The switching devices 90 have an on state and an off state, and the processing device 30 is used to control the on / off state of the switching devices 90.

[0267] In some embodiments, the processing device 30 can be configured to switchably operate in a first mode and a third mode; in the first mode, the switching device 90 is locked in a selective trigger state, such that at most one of the at least two switching devices 90 is allowed to enter the on state at the same time; in the third mode, two or more switching devices 90 are allowed to be in the on state simultaneously.

[0268] In other words, the first mode of the processing device 30 is an optional feature that the user can freely choose whether to enter. When the user sets the processing device 30 to a non-first mode (e.g., the third mode), the smart switch functions as a general smart switch and is suitable for common smart control scenarios (e.g., lighting control scenarios). When the user sets the processing device 30 to the first mode, the smart switch is locked in a selective trigger state and is suitable for some special application scenarios (e.g., the selective switching application scenario between multiple speeds of the same electrical device such as the aforementioned fresh air system). Due to the introduction of the first mode, the control objects and usage scenarios of the smart switch provided in this embodiment are more diversified, giving users more freedom of choice.

[0269] Unlike the third mode of the smart switch, in the first mode, only one of the multiple on / off devices 90 of the smart switch can be turned on at the same time, and multiple on / off devices 90 cannot be turned on at the same time, so that the multiple on / off devices 90 of the smart switch have a selective triggering state, which can be adapted to the application scenario of selective switching between multiple gears of the same electrical device.

[0270] Furthermore, in some embodiments, the smart switch is adapted to be connected to a target circuit and used to control the target circuit through the on / off device 90, so that when a multi-speed device is connected to the target circuit, the multiple on / off devices 90 of the smart switch control the on / off of the circuits of multiple speeds of the multi-speed device respectively; wherein in a first mode, the processing device 30 of the smart switch locks the on / off device 90 to a selective trigger state, so that at most one of the at least two on / off devices 90 is allowed to enter the on state at the same time, so as to selectively trigger multiple speeds of the multi-speed device.

[0271] The triggering of multiple gear positions of the electrical device can be understood as controlling the connection and disconnection of the corresponding gear positions, such as controlling a gear position to switch from disconnected to connected, or from connected to disconnected.

[0272] Furthermore, in the first mode, the processing device 30 is specifically configured to: upon receiving an instruction to switch a switching device 90 to the on state, if another switching device 90 is already in the on state, first switch the other switching device 90 to the off state, and then switch the first switching device 90 to the on state. Specifically, when switching on a new switching device 90, the processing device 30 will first turn off the already connected switching device 90 to avoid simultaneously connecting two switching devices 90.

[0273] In some embodiments, such as Figure 39 As shown, the on / off device 90 includes:

[0274] The operating area for receiving control, and the electronic switch corresponding to each operating area;

[0275] The processing device 30 can detect the manipulation applied to the operation area and control the corresponding electronic switch to be turned on and off accordingly; when the electronic switch is turned on, the corresponding on / off device 90 is turned on, and when the electronic switch is turned off, the corresponding on / off device 90 is turned off.

[0276] The operating area can be understood as an area for receiving user control. For example, when the smart switch is implemented as a push-button switch, the operating area can be, for example, the button 21 of the push-button switch (e.g., Figures 1-10 In the embodiments described, the button operation area is formed by the button 21) that can be manipulated and displaced; when the smart switch is implemented as a touch switch, the operation area can be, for example, a designated touch area on the touch panel of the touch switch; when the smart switch is implemented as a screen switch, the operation area can be, for example, the operation area where the virtual operation controls are located on the touch screen of the screen switch. Furthermore, the manipulation can also be, for example, the manipulation of pressing / releasing a button, the manipulation of touching / approaching to sense the touch area, touch screen manipulation, etc. In short, the definition of the operation area and the corresponding manipulation type will be different depending on the type of smart switch. However, regardless of how the implementation form and principle of the operation area change, as long as it is an area used to receive user manipulation to trigger the smart switch, it should not deviate from the scope protected by the embodiments of the present invention. Any operation area formed by any structure in the art that can generate a trigger signal based on user manipulation can be used as an optional solution of the embodiments of the present invention.

[0277] The electronic switch can be understood as a component or combination of components having an on and off state, such as an electronic switch using a relay or a thyristor as the actuating element. The electronic switch is connected to a target circuit to control the on / off state of the power supply circuit of electrical equipment that draws power from that target circuit. When the electronic switch is in the on state, the target circuit is connected and the electrical equipment is powered; when the electronic switch is in the off state, the target circuit is turned off and the electrical equipment is de-energized.

[0278] For example, if the smart switch has three on / off devices 90, then:

[0279] When the smart switch is used in a lighting control scenario, the processing device 30 can be set to a third mode. The electronic switches corresponding to the three on / off devices 90 are respectively connected to three lamps. The three corresponding operation areas are respectively used to trigger the power on and power off of the control channel formed by the corresponding electronic switch, thereby controlling the lighting of the lamps in the corresponding control channel. In the third mode, the smart switch supports the simultaneous activation of the three electronic switches to turn on the three lamps at the same time.

[0280] For example, when the smart switch controls a fresh air system, the processing device 30 can be set to a first mode; the three on / off devices 90 of the smart switch correspond to three electronic switches that control the high, medium, and low speeds of the fresh air system respectively. As is known to those skilled in the art, the three speeds of a fresh air system are selectively triggered at any given time; that is, the fresh air system will not be turned on at two speeds simultaneously (e.g., simultaneously turning on the high and low speeds), otherwise it would affect the lifespan of the fresh air system. Existing smart switches, because they support the simultaneous activation of multiple control channels, are not suitable for this scenario. The smart switch provided in this embodiment, in the first mode, allows at most one electronic switch corresponding to an operating area to be activated at a time, which can well adapt to the selective triggering of multiple speeds of the fresh air system within the same time period.

[0281] Specifically, each operating area of ​​the smart switch is equipped with a detection switch. Applying manipulation to the operating area triggers the corresponding detection switch, thereby transmitting a corresponding trigger signal to the processing device 30. This allows the processing device 30 to identify the operating area being manipulated and control the corresponding electronic switch to turn on or off accordingly. The trigger signal can be understood as any electrical signal that can be recognized by the processing device 30. For example, when the operating area is set as a designated touch area of ​​the touch panel, the detection switch can be, for example, a sensing electrode coupled to a capacitive proximity sensor chip of the touch panel; when the operating area is set as a button 21, the detection switch can be, for example, a tactile switch. The button 21 directly or indirectly abuts against the tactile switch. The button 21 can be pressed to cause displacement and can be released to reset. The user can trigger the tactile switch by pressing the button 21.

[0282] Furthermore, the processing device 30 is also configured to: in the third mode, allow each operating area to switch its operating mode independently; the operating modes include on / off mode and wireless mode.

[0283] In the on / off mode, the operation area receives commands to switch the on / off state of the corresponding electronic switch; that is, in the on / off mode, the operation area is equivalent to the mechanical button of a traditional mechanical switch, used to switch the on / off state of the corresponding control channel. In the wireless mode, the operation area receives commands to send a specified wireless signal. The electronic switch corresponding to the operation area in wireless mode remains on and will not disconnect according to the command received by the operation area, to prevent the smart device connected to the electronic switch from being disconnected due to power failure. The wireless signal can be a control message compiled based on a predetermined protocol to control a target controlled device (this target controlled device can be an electrical device connected to the target circuit, or other electrical devices that can directly or indirectly establish a controlled or controlling relationship with the smart switch, such as smart devices connected to the same gateway network and joined to the same gateway).

[0284] Furthermore, unlike the global effect of the first mode in the above embodiments (i.e., entering the first mode is done on a unit-by-unit basis for smart switches, and once the first mode is entered, the functions of all operating areas are affected), the operating modes of the operating areas in this embodiment support local switching. That is, switching is performed on a unit-by-unit basis for each operating area, and the switching of the operating modes of each operating area can be performed independently without affecting each other, thus enriching the control forms of smart switches with multiple operating areas. Users can set corresponding operating modes for each operating area according to specific application scenarios and controlled objects. Furthermore, each operating area can enter on / off mode to have the on / off control function of traditional mechanical switches, and can enter wireless mode to extend target devices, so that the controlled terminal is not limited to target devices directly electrically connected to the electronic switch of the smart switch. For example, when the smart switch has three operating areas, if the controlled object is only two lamps, then two of the three operating areas are set to on / off mode to control the on / off of the two lamps, and the other is set to wireless mode to control other smart devices.

[0285] In some embodiments, the processing device 30 is further configured to lock all operating areas to an on / off mode in the first mode. If there are operating areas in wireless mode before entering the first mode, entering the first mode will trigger the processing device 30 to forcibly switch all operating areas in wireless mode to the on / off mode. In other words, in this embodiment, the first mode will have higher priority, so that all operating areas are forced to enter the on / off mode in the first mode, and operating areas set to wireless mode will also be forcibly switched to the on / off mode. Some user-defined smart scenarios associated with the wireless modes of each operating area will also be disabled. At this time, the smart switch can be regarded as a gear switching switch dedicated to multi-gear devices.

[0286] In some embodiments, the processing device 30 is further configured to, when entering the first mode from a non-first mode, force all electronic switches corresponding to the operating areas to be switched to the off state.

[0287] Furthermore, when the smart switch is triggered to enter the first mode from a non-first mode (e.g., from the third mode to the first mode), regardless of how many electronic switches were previously in the on state, all electronic switches will be switched to the off state. This ensures that when initially entering the first mode, the control channels of each operating area of ​​the smart switch are in the off state, thereby turning off the connected electrical equipment to facilitate subsequent user operations.

[0288] In some embodiments, the processing device 30 can be configured to have a second mode; in the second mode, the on / off state of the electronic switches corresponding to all operating areas in the wireless mode is locked, so that the electronic switches in the second mode will not be disconnected by other communication commands other than the first mode.

[0289] The communication commands involved here may be, for example, voice control commands from a smart speaker, control commands sent by a mobile phone to switch the on / off state of the electronic switch in the operating area to switch wireless modes, or control commands from a wireless switch or wall switch paired with the smart switch.

[0290] In other words, in the second mode, the electronic switch corresponding to the wireless mode operating area will neither be disconnected by user operation nor by other communication commands besides the first mode. In some application scenarios, the smart switch is connected to a target circuit, and this target circuit is connected to at least one smart device. If the corresponding electronic switch is disconnected, the smart device will lose power and go offline, causing inconvenience to the user. This problem can be solved by entering the second mode. In the second mode, the on / off state of the electronic switch corresponding to the wireless mode operating area is locked, thus solving the problem of smart devices always losing power and going offline in some application scenarios, and improving the limitations of smart switch usage scenarios. Furthermore, users can control whether the smart switch enters the second mode through their terminal devices, which also increases the user's freedom of choice.

[0291] In this embodiment, the first mode has a higher priority than the second mode. That is, when the smart switch enters the first mode, all operating areas will be forced to enter the on / off mode, and the operating areas set to wireless mode will also be forced to switch to the on / off mode, causing the second mode to fail.

[0292] In some embodiments, the processing device 30 is capable of establishing a communication connection with an external terminal device and is capable of implementing at least one of the following controls based on the operation of the terminal device:

[0293] According to a first control command originating from a terminal device that has established a communication connection, the device switches to the first mode, the second mode, or the third mode.

[0294] In the second or third mode, the working mode of each operating area is switched independently according to the second control command of the terminal device;

[0295] In the first and third modes, the on and off states of the electronic switches in the operation area of ​​the terminal device are switched according to the third control command of the terminal device. In the first mode, at most one electronic switch can still be turned on at the same time through the third control command.

[0296] The first control command, the second control command, and the third control command are all compiled according to a predetermined communication protocol and are different from each other.

[0297] In one alternative implementation, such as Figure 40As shown, the first, second, and third control commands can originate from an application on a terminal device (such as a mobile app compatible with the smart switch). Specifically, the application has an interface that displays the smart switch's configuration options. For example, the interface displays a clickable control indicating a first mode and a second mode. When the user clicks the corresponding control to activate it, the application generates and sends the corresponding control command based on the mode of the clicked control, causing the smart switch to enter the corresponding operating mode.

[0298] Furthermore, the processing device 30 has communication functions (e.g., an external Bluetooth communication unit, or a Bluetooth module integrating communication and processing functions), and can establish a communication connection with terminal devices through network configuration. Specifically, the processing device 30 has a network configuration mode. In network configuration mode, the message sent by the processing device 30 of the smart switch due to the operation area being controlled can be a network configuration message. This network configuration message is used to trigger a designated device to add the smart switch to the target network. The network configuration mode can be understood as a mode in which the smart switch is suitable for network configuration with the target network, thereby joining the target network.

[0299] In a specific example, the processing device 30 of the smart switch includes a Bluetooth module that communicates externally via BLE MESH. The operation area includes buttons 21. The smart switch can enter a network configuration mode in response to a specified network configuration operation. In this mode, the processing device 30 sends a predefined network configuration message. This message is used by the Bluetooth gateway or terminal device to detect the smart switch and display it on the app interface. The user can trigger the pre-defined network configuration operation by clicking the smart switch, enabling it to access the target network through the Bluetooth gateway. After accessing the target network, the smart switch can establish control and / or controlled relationships with other smart devices already connected to the target network, thus enriching the application scenarios of the smart switch.

[0300] In a further example, the designated distribution network control may be, for example:

[0301] Double-click any button 21 (click the button 21 twice consecutively within 500ms). After a successful double-click, the corresponding indicator will flash twice continuously within 1.2s, indicating that the smart switch has entered the pre-reset state.

[0302] If button 21 is pressed for the third time within 1.2 seconds, the indicator will stop flashing. Then, if button 21 is pressed for the third time for more than 5 seconds, the indicator will start flashing again after 5 seconds, indicating that the network configuration mode has been successfully entered.

[0303] If no button 21 is pressed within 1.2 seconds, the flashing will stop after it ends.

[0304] If button 21 is pressed within 1.2 seconds but released normally (i.e., not held down for more than 5 seconds), a normal toggle action is triggered (i.e., the electronic switch corresponding to button 21 is toggled from its current state to another state, such as from the current on state to the off state), and the indicator stops flashing.

[0305] Furthermore, the processing device 30 also has a pairing mode, which differs from the global effect of the distribution mode in the above embodiment (i.e., the distribution mode performs distribution operations on a unit of smart switches), while the pairing mode in this embodiment is based on an operation area.

[0306] For example, when the operation area is implemented as button 21, the user can press and hold a button for more than 3 seconds to put the smart switch into the pairing mode of button 21. At this time, the user can click a button 21 of a wireless switch to make the wireless switch transmit the corresponding pairing message. The smart switch can receive the pairing message and store the ID of the wireless switch carried in the pairing message (such as a pre-set serial number used to uniquely identify the wireless switch) to realize the pairing of the button 21 of the smart switch with the corresponding button 21 of the wireless switch. Subsequently, the control channel of the corresponding button 21 of the smart switch can be controlled through the button 21 of the wireless switch.

[0307] In another example, when the operation area is implemented as button 21, the user can click on a button 21 to put the smart switch into the pairing mode of that button 21. Then, the user can press and hold a button on another smart switch for more than 3 seconds to put that smart switch into the pairing mode of its corresponding button 21 as well. This enables mutual control pairing of the corresponding buttons 21 of the two smart switches, allowing the user to control the corresponding button 21 of the other smart switch using the corresponding button 21 of one smart switch. If one smart switch enters the first mode, the control logic of the first mode will still apply when the two smart switches control each other.

[0308] In a further example, the pairing steps for smart switch A and smart switch B can be as follows: Press and hold the first button of A for 3 seconds to enter pairing mode. At this time, press the second button of B for 3 seconds to complete the pairing with the first button of A. After successful pairing, the smart switch sends a corresponding indicator signal to indicate that the mutual control learning is successful. In subsequent control, the electronic switch corresponding to the first button of A and the electronic switch corresponding to the second button of B will be completely synchronized. If one of the smart switches enters wireless mode, the synchronization will not continue.

[0309] The pairing steps for smart switches A, B, and C can be as follows: If A and B are already paired, and C wants to pair with A and B, simply pair C with A (or B). Then, the corresponding buttons 21 of the three smart switches A, B, and C will be successfully paired, and the corresponding electronic switches, indicator lights, and APP status of the three switches will be completely synchronized. If the corresponding button 21 of one of the smart switches enters wireless mode, the synchronization status will be broken.

[0310] If smart switches A and B are successfully paired, and smart switches C and D are successfully paired, pairing A and C will not result in a pairing between them. At least one of A or C must be cleared of its existing pairing before pairing A and C can be attempted again. For example: Press and hold the corresponding button 21 of A to clear the pairing, then pair A again; at this time, A, C, and D will be synchronized. Alternatively, press and hold the corresponding button 21 of C to clear the pairing, then pair A and C; at this time, A, B, and C will be synchronized. Or, simultaneously clear the pairing of the corresponding buttons 21 of A and C, then pair A and C; at this time, A and C will be synchronized.

[0311] In one example, pressing and holding a button 21 for more than 12 seconds can clear the pairing relationships under that button 21, including the pairing relationships of paired wireless switches and paired smart switches.

[0312] See Figure 41 As shown, the present invention also provides an intelligent control system, characterized in that it includes an intelligent switch and a multi-speed device.

[0313] The aforementioned multi-speed device should be understood as an electrical device with at least two speeds. The multiple speeds are used to control the electrical device to enter different working states, and the multiple speeds are generally selectively triggered. For example, the multi-speed device can be a fresh air unit or a ceiling fan (electric fan), and its multiple speeds are high wind speed, medium wind speed and low wind speed. Its different working states can be, for example, high wind speed working state, medium wind speed working state and low wind speed working state.

[0314] The smart switch may be, for example, the smart switch described in the above embodiments, wherein the multiple on / off devices 90 of the smart switch are respectively used to control the on / off of each gear of the multi-gear device, so as to control the on / off of each gear of the multi-gear device through the on / off devices 90 of the smart switch; wherein the smart switch is adapted to be configured to enter a first mode so that at most one gear of the multi-gear device is turned on at the same time.

[0315] Furthermore, in non-first mode, the smart switch still has the functions of a regular smart switch, while in first mode, the smart switch is equivalent to a dedicated switch for the multi-speed device, allowing users to freely change the function mode of the smart switch according to different usage environments without having to configure a special switch for the multi-speed device.

[0316] The following description uses the multi-level device as an example of a fresh air system to further illustrate the embodiments of the present invention:

[0317] See Figure 42 The diagram shown is a control block diagram between the smart switch and the fresh air unit.

[0318] Specifically, such as Figure 42 As shown, each of the switching devices 90 is provided with an operating area and an electronic switch. Therefore, the smart switch may include three switching devices 90, wherein the electronic switches correspond to electronic switch 1, electronic switch 2 and electronic switch 3 as shown in the figure.

[0319] The intelligent switch includes a first power terminal (e.g., neutral wire N input terminal) and a second power terminal (e.g., live wire L input terminal). The first power terminal is used to connect to the common terminal of the fresh air unit, such as the neutral wire terminal. The second power terminal is used to simultaneously power the processing device 30 (e.g., converting the input AC power into 5V DC power) and the switching device 90. The three output terminals of the intelligent switch are respectively electrically connected to the three control terminals of the fresh air unit, i.e., connected to the three air outlet parameter control lines H, M, and L of the fresh air unit, for example, they can represent the three fan speed levels of the fresh air unit: high, medium, and low. The three electronic switches are also electrically connected to the processing device 30 through RELAY-1, RELAY-2, and RELAY-3 respectively, to receive control signals sent by the processing device 30.

[0320] According to embodiments of this disclosure, each electronic switch is driven by the processing device 30 through a drive circuit (such as...). Figures 33-35 ,as well as Figure 15 , Figure 16 The relay 40 shown acts as an electronic switch, and the relay drive circuit 80 acts as a drive circuit. The drive circuit is configured to control the on / off state of each electronic switch based on the control signal. The live wire input terminal of the smart switch also serves as the power supply circuit 50 (e.g., Figure 33The first power conversion circuit 501 shown provides a first power supply to the electronic switches (e.g., converting the input AC power into 5V DC power). The drive circuit is electrically connected to the processing device 30 and receives control signals input by the processing device 30 through RELAY-1, RELAY-2, and RELAY-3, and controls the opening and closing of each electronic switch based on the control signals. Furthermore, the processing device 30 can drive the individual electronic switches to close via RELAY-1, RELAY-2, and RELAY-3 to control the operating state of the fresh air unit. For example, the drive circuit can drive the connection and disconnection of the output terminal and the power supply terminal according to the control signals sent by the processing device 30 to control the on / off of the fresh air unit's outlet air parameter control line H, thereby controlling the operating state of the fresh air unit.

[0321] In the first mode, the smart switch is equivalent to a fan controller dedicated to the fresh air unit. The processing device 30 of the smart switch can open at most one electronic switch at the same time. For example, when the electronic switch 1 corresponding to the operation area 1 is turned on, if the processing device 30 detects the operation of the operation area 2, it will first trigger the electronic switch 1 to turn off through RELAY-1, and then trigger the electronic switch 2 to turn on through RELAY-2. As a result, the working state of the fresh air unit will be that the high wind speed is turned off and the medium wind speed is turned on. That is, when the three wind speeds are controlled by the smart switches of multiple operation areas, they can still follow the control logic of one speed being triggered at a time.

[0322] Optionally, the electronic switch is configured as a relay (e.g., as shown in the image). Figures 33-35 , Figure 15 , Figure 16 The relay 40 shown can be driven by, for example, the corresponding driving circuit. Figures 33-35 The relay drive circuit 80 shown can be referenced in the following diagram for its specific circuit principle. Figures 33-35 (For understanding the corresponding embodiments). Each relay includes a pair of magnetically controlled electrodes, which are electrically connected to the fresh air unit via an air outlet parameter control line. The magnetically controlled electrode pair includes two conductive contacts. If the two conductive contacts of the magnetically controlled electrode pair are connected, the air outlet parameter control line is connected, and the fan operates at the specified air outlet parameter. If the two conductive contacts of the magnetically controlled electrode pair are not connected, the air outlet parameter control line is de-energized.

[0323] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
