Abstract

The utility model provides a switch, and belongs to the technical field of household appliances. The switch comprises a first external port, a second external port, a control unit, a switching circuit, a power taking circuit and a battery assembly. And when the switching circuit is closed, the first external port is communicated with the second external port. The power taking circuit converts the alternating current output by the switching circuit into a direct current line and outputs the direct current line to the control unit so as to supply power to the control unit. And when the switching circuit is disconnected, the first external port and the second external port are disconnected. The power taking circuit cannot supply power to the control unit, but the battery assembly supplies power to the control unit. Therefore, under the condition that the switching circuit is opened or closed, the switch can supply power to the control unit, so that a user can control the electric appliance through the control unit. Therefore, the switch is only provided with two external ports, and the installation cost and difficulty are reduced. When a traditional switch is replaced by the switch provided by the invention, a null line does not need to be added in the junction box.

Description

Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and in particular to a switch. Background Art

[0002] Smart switches can achieve intelligent control of electrical appliances, such as remote control and voice control of the switching and brightness of electrical appliances.

[0003] In the related art, an intelligent switch includes a control unit, a switching circuit, and a power supply circuit. The control unit is electrically connected to the switching circuit and is used to control the closing and opening of the switching circuit. The power supply circuit is electrically connected to the output end of the switching circuit and is used to convert the AC power output by the switching circuit into DC power, thereby powering the control unit. When the switching circuit is disconnected, the switching circuit no longer outputs current, and therefore the power supply circuit cannot power the control unit. Therefore, in order to ensure that the control unit can be powered after the switching circuit is disconnected, the control unit must also be electrically connected to the neutral line.

[0004] However, traditional switches are only electrically connected to the live and light wires, so the junction box that houses the switch does not have a neutral wire. Therefore, when replacing a traditional switch with a smart switch, a neutral wire must be added to the junction box. This increases the difficulty and cost of replacing the switch.

These drawings and textual descriptions are not intended to limit the scope of the present disclosure in any way, but rather to illustrate the concepts of the present disclosure to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0049] The terms used in the embodiments of the present disclosure are intended only to explain the embodiments of the present disclosure and are not intended to limit the present disclosure. Unless otherwise defined, technical or scientific terms used herein should have the same ordinary meaning as those of ordinary skill in the art to which the present disclosure pertains.

Terms such as "include" or "comprising" mean that the elements or objects preceding the term "include" or "comprising" include the elements or objects listed after the term and their equivalents, and do not exclude other elements or objects. Terms such as "connected" or "connected" are not limited to physical or mechanical connections but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0050] The switch can realize intelligent control of electrical appliances, such as remote control and voice control of the switch and brightness of electrical appliances. Figure 1 As shown, the switch includes a control unit 1, a switching circuit 2 and a power supply circuit 3. The switch has a first external port 10, a second external port 20 and a second neutral line interface 50. The switching circuit 2 is electrically connected to the first external port 10, the second external port 20 and the control unit 1. The power supply circuit 3 is electrically connected to the output end of the switching circuit 2, and is used to convert the AC power output by the switching circuit 2 into DC power, thereby powering the control unit 1. The switching circuit 2 is electrically connected to the electrical appliance 30 through the second external port 20, and the other end of the electrical appliance 30 is electrically connected to the first neutral line interface 40. When the switching circuit 2 is disconnected, the switching circuit 2 no longer outputs current, so the power supply circuit 3 cannot power the control unit 1. Therefore, in order to ensure that the control unit 1 can be powered on after the switching circuit 2 is disconnected, the control unit 1 must also be electrically connected to the second neutral line interface 50.

[0051] However, traditional switches are only electrically connected to the live and light wires, so the junction box housing the switch does not include a neutral wire. Therefore, when replacing a traditional switch with a switch capable of intelligently controlling electrical appliances, a neutral wire must be added to the junction box. This increases the difficulty and cost of replacing the switch.

[0052] In view of the above technical problems, the present disclosure provides a switch, such as Figure 2As shown, the switch includes a first external port 10, a second external port 20, a control unit 1, a switching circuit 2, a power supply circuit 3, and a battery pack 4. The switching circuit 2 is located in the circuit between the first external port 10 and the second external port 20. The first end 21 of the switching circuit 2 is electrically connected to the first external port 10, the second end 22 is electrically connected to the second external port 20, and the third end 23 is electrically connected to the control unit 1. The control unit 1 is used to control the closing and opening of the switching circuit 2. The input end 31 of the power supply circuit 3 is electrically connected to the circuit between the first end 21 and the second external port 20, and the first output end 32 of the power supply circuit 3 is electrically connected to the control unit 1. The power supply circuit 3 is used to convert the AC power output by the switching circuit 2 into DC power. The battery pack 4 is electrically connected to the control unit 1 and is used to supply power to the control unit 1 when the switching circuit 2 is disconnected.

[0053] The first external port 10 is connected to the mains, the switch circuit 2 is electrically connected to the electrical appliance 30 via the second external port 20, and the other end of the electrical appliance 30 is electrically connected to the first neutral line interface 40. Thus, when the switch circuit 2 is closed, the two ends of the electrical appliance 30 are electrically connected to the first external port 10 and the first neutral line interface 40, respectively, turning on the electrical appliance 30.

[0054] The technical solution provided by the embodiment of the present disclosure is to set a battery assembly 4 so that the switch can always supply power to the control unit 1. Figure 3 As shown, when the switch circuit 2 is closed, the first external port 10 and the second external port 20 are connected. The power circuit 3 is electrically connected to the switch circuit 2, and the power circuit 3 converts the AC power output by the switch circuit 2 into a DC line and outputs it to the control unit 1, thereby supplying power to the control unit 1. Figure 4 As shown, when the switch circuit 2 is disconnected, the first external port 10 and the second external port 20 are disconnected. The switch circuit 2 no longer outputs current, and the power circuit 3 cannot supply power to the control unit 1, and the battery assembly 4 supplies power to the control unit. Therefore, when the switch circuit 2 is disconnected or closed, the switch can supply power to the control unit 1, so that the user can control the switch and brightness of the electrical appliance 30 through the control unit 1. In this way, when installing the switch, there is no need to connect the switch to the neutral wire, and the switch only needs to be provided with two external ports, which reduces the installation cost and difficulty. When replacing a traditional switch with the switch provided in the embodiment of the present disclosure, there is no need to add a neutral wire in the junction box.

[0055] Next, the implementation of the battery assembly 4 is described by way of example.

[0056] In some examples, such as Figure 5As shown, the battery assembly 4 includes a rechargeable battery 41 and a charging circuit 42. The rechargeable battery 41 is electrically connected to the control unit 1 and the charging circuit 42. The charging circuit 42 is also electrically connected to the second output terminal 33 of the power extraction circuit 3. The power extraction circuit 3 is used to convert the AC power output by the switch circuit 2 into DC power, so that the charging circuit 42 charges the rechargeable battery 41 when the switch circuit 2 is closed.

[0057] like Figure 6 As shown, when the switch circuit 2 is closed, the switch circuit 2 outputs AC power, and the power circuit 3 converts the AC power into DC power. Then the DC power is supplied to the charging circuit 42, so that the charging circuit 42 can charge the rechargeable battery. In this way, the rechargeable battery 41 can have a higher power, thereby ensuring that the rechargeable battery 41 can continue to power the control unit 1 when the switch circuit 2 is disconnected (such as Figure 7 shown).

[0058] When the switch circuit is disconnected for a long time, the charging circuit 42 cannot supply power to the charging electric vehicle for a long time. This may cause the power of the rechargeable battery 41 to be exhausted, thereby failing to supply power to the control unit 1. Therefore, in some examples, such as Figure 5 As shown, the rechargeable battery 41 has an external interface 410, and the rechargeable battery 41 is electrically connected to an external power source through the external interface 410. In this way, when the power of the rechargeable battery 41 is exhausted, the user can charge the rechargeable battery 41 through the external interface 410.

[0059] In some examples, the external interface 410 is a Type-C interface. Since most common electrical appliances have charging ports that are Type-C interfaces, the external interface 410 is set to a Type-C interface to facilitate charging the rechargeable battery 41.

[0060] Of course, in other examples, the external interface 410 may also be set to other types of interfaces, which is not specifically limited in the embodiments of the present disclosure.

[0061] In some examples, the rechargeable battery 41 is a lithium battery. Lithium batteries have a large capacity and can power the control unit 1 for a long time.

[0062] In some examples, the switch has a housing, and the rechargeable battery 41 is detachably connected to the housing. In this way, when the rechargeable battery 41 needs to be charged or replaced, the rechargeable battery 41 can be removed from the switch.

[0063] In some examples, such as Figure 2 As shown, the switch also includes a relay 5. Figure 3As shown, the two ends of the relay 5 are electrically connected to the control unit 1 and the battery assembly 4 respectively. The relay 5 is used to disconnect the control unit 1 from the battery assembly 4 when the switch circuit 2 is closed. When the control unit 1 sends a closing switch signal to the switch circuit 2, the control unit 1 also sends an instruction to the relay 5 to cut off the circuit between the battery assembly 4 and the control unit 1. Figure 4 As shown, when the control unit 1 sends a switch-off signal to the switch circuit 2 , the control unit 1 also sends an instruction to the relay 5 to connect the circuit between the battery assembly 4 and the control unit 1 .

[0064] For example, Figure 5 As shown, both ends of the relay 5 are electrically connected to the rechargeable battery 41 and the control unit 1. Figure 6 As shown, when the switch circuit 2 is closed, only the power circuit 3 supplies power to the control unit. The charging circuit 42 charges the rechargeable battery 41, and the rechargeable battery 41 is disconnected from the control unit 1. This is beneficial for the battery assembly 4 to preserve power and can improve the efficiency of the charging circuit 42 in charging the rechargeable battery 41. Figure 7 As shown, when the switch circuit 2 is disconnected, the relay 5 connects the rechargeable battery 41 and the control unit 1 , so that the rechargeable battery 41 supplies power to the control unit 1 .

[0065] The following is an exemplary description of the implementation of the control unit 1.

[0066] In some examples, such as Figure 5 As shown, the control unit 1 includes an MCU chip 11, a communication module 12, and a touch screen 13. The MCU chip 11 is electrically connected to the third terminal 23 of the switch circuit 2, the communication module 12, and the touch screen 13. The communication module 12 and the touch screen 13 are used to send instructions to the MCU chip 11, so that the MCU chip 11 controls the closing and opening of the switch circuit 2. The communication module 12 can achieve wireless communication with the electrical appliance via BLE (Bluetooth Low Energy), WIFI (Wireless Fidelity), or ZigBee (ZigBee protocol).

[0067] In the related art, although there are single-fire switches that do not need to be connected to the neutral wire, they do not have touch screens. The reason is that after turning off the lights, the single-fire switch is not completely disconnected from the electrical appliance 30, but its own resistance is increased, so that only a weak current flows between the single-fire switch and the electrical appliance. The weak current can power the single-fire switch, but it does not reach the driving current of the electrical appliance 30. Therefore, when the electrical appliance is turned off, the single-fire switch can still work. Since the driving current of the touch screen is relatively large, if a touch screen is added to the single-fire switch, the current between the single-fire switch and the electrical appliance will be relatively large after turning off the lights. This current may reach the driving current of the electrical appliance 30, so that the electrical appliance 30 cannot be completely turned off.

[0068] In the technical solution provided by the embodiment of the present disclosure, the switch circuit 2 cuts off the circuit between the electrical appliance 30 and the switch in the light-off state, so no current flows into the electrical appliance 30. In this way, even if the switch has a touch screen 13, the driving current of the touch screen 13 will not affect the electrical appliance.

[0069] In some examples, such as Figure 8 As shown, the touch screen 13 includes a light switch module 131 , a brightness adjustment module 132 and a color temperature adjustment module 133 , and the light switch module 131 , the brightness adjustment module 132 and the color temperature adjustment module 133 are all electrically connected to the MCU chip 11 .

[0070] When a user uses the switch, they touch the light switch module 131, which sends a light-on or light-off signal to the MCU chip 11. The MCU chip 11 then controls the closing and opening of the switch circuit 2 to turn the appliance on or off. The brightness adjustment module 132 sends a brightness adjustment instruction to the communication module 12 via the MCU chip 11. The communication module 12 then sends the instruction to the appliance, thereby adjusting the appliance's brightness. The color temperature adjustment module 133 sends a color temperature adjustment instruction to the communication module 12 via the MCU chip 11. The communication module 12 then sends the instruction to the appliance, thereby adjusting the appliance's color temperature.

[0071] In some examples, the switch is used to control a lamp, that is, the electrical appliance 30 is a lamp.

[0072] Of course, in other examples, the electrical appliance 30 may also be a television or other household appliances.

[0073] The above descriptions are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present disclosure shall be included in the scope of protection of the present disclosure.
