Description

Technical Field

[0001] This invention belongs to the field of switch technology, specifically a composite switch with a power failure protection structure. Background Technology

[0002] A switch is a common electronic component used to control the starting and stopping of electrical appliances. It contains one or more electronic contacts. When a contact is closed, the appliance is connected, allowing current to flow through it. When a contact is open, the appliance is not connected, and current is not allowed to flow through it.

[0003] Currently, during power outages, due to human negligence or accidental activation, the contacts in switches are easily kept in the connected state. When power is suddenly restored, the electrical appliances are easily damaged due to factors such as aging wires or voltage increases during the power surge. Therefore, existing switches cannot provide power-off protection for electrical appliances and urgently need improvement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a composite switch with a power failure protection structure.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A composite switch with a power failure protection structure includes a housing, a control panel, a power connection component, an adsorption component, and a repulsion component.

[0007] The housing is mounted on a wall, the control panel is rotatably mounted on the side of the housing away from the wall, and the power connection assembly is disposed inside the housing.

[0008] When the control panel is rotated in the first direction, the power connection component enables the electrical appliance to conduct electricity.

[0009] When the control panel is rotated in the second direction, the power connection component can cut off the power to the electrical appliance.

[0010] The adsorption component is fixedly disposed on the inner wall of the housing, and the repulsion component is disposed on one side of the adsorption component and slides in cooperation with the inner wall of the housing.

[0011] When there is no power outage, the adsorption component is used to adsorb the repulsion component.

[0012] During a power outage, the adsorption component releases the repulsion component, which moves to a predetermined position to provide a repulsive force to the control panel, thereby driving the control panel to rotate in the second direction.

[0013] As a further improvement of the present invention: the control panel includes a pressure plate.

[0014] One end of the pressure plate is embedded inside the housing and is rotatably connected to the inner wall of the housing via a rotating rod.

[0015] The power connection assembly includes a first conductive block and two sets of second conductive blocks.

[0016] The first conductive block is fixedly mounted on the side wall of the pressure plate inside the housing. Two sets of the second conductive blocks are fixedly mounted on the inner wall of the housing and distributed opposite to the first conductive block. One set of the second conductive blocks is connected to the mains power, and the other set of the second conductive blocks is connected to the electrical appliance.

[0017] As a further improvement of the present invention: the repulsion component includes a second slider and a second permanent magnet disposed on one side of the second slider.

[0018] The second slider slides against the inner wall of the housing, and a third permanent magnet, which repels the second permanent magnet, is disposed on one side of the pressure plate inside the housing.

[0019] The adsorption assembly includes an electromagnet and a first permanent magnet.

[0020] The electromagnet is fixedly mounted on the inner wall of the housing and connected to the mains power. The first permanent magnet is located on one side of the second slider and can be attracted by the electromagnet.

[0021] As a further improvement of the present invention: a second guide rail is fixedly provided on the inner wall of the housing, a second limiting block is fixedly provided at one end of the second guide rail, and the second slider slides in cooperation with the second guide rail.

[0022] The second limiting block and the second slider are connected by a first elastic element, which provides elastic tension to the second slider.

[0023] As a further improvement to the present invention: a second elastic element is further provided inside the housing.

[0024] One end of the second elastic element is connected to the inner wall of the housing, and the other end is connected to the pressure plate, which provides elastic support to the pressure plate to maintain the stability of the pressure plate after it rotates in the first direction or the second direction.

[0025] As a further improvement of the present invention: a first guide rail is fixedly provided on one side of the pressure plate inside the housing, a first limiting block is fixedly provided at the end of the first guide rail, a first slider is slidably provided on the first guide rail, and the end of the second elastic member away from the inner wall of the housing is connected to the first slider.

[0026] As a further improvement of the present invention: the first elastic element and the second elastic element are springs or metal sheets.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] In this embodiment of the invention, when it is necessary to turn on the appliance, the control panel can be rotated in the first direction, and the power connection component enables the appliance to conduct electricity. At this time, the appliance is connected to the mains power and works. When it is necessary to turn off the appliance, the control panel can be rotated in the second direction opposite to the first direction, and the power connection component enables the appliance to disconnect from the power supply, and the appliance stops working. During a power outage, the adsorption component can release the repulsion component, causing the repulsion component to move to a predetermined position. Subsequently, the repulsion component applies a repulsive force to the control panel to drive the control panel to rotate in the second direction, so that the power connection component enables the appliance to disconnect from the power supply. This avoids the appliance from being damaged by a sudden surge in voltage when power is restored. Compared with the prior art, this invention can automatically disconnect the connection between the appliance and the switch during a power outage, preventing damage to the appliance due to a surge in voltage when power is restored, thereby achieving power outage protection for the appliance.

Detailed Implementation

[0033] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0034] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0035] Please see Figure 1 This embodiment provides a composite switch with a power-off protection structure, including a housing 10, a control panel 20, a power-connecting component 30, an adsorption component 40, and a repulsion component 50. The housing 10 is mounted on a wall, and the control panel 20 is rotatably mounted on the side of the housing 10 away from the wall. The power-connecting component 30 is disposed inside the housing 10. When the control panel 20 rotates in a first direction, the power-connecting component 30 enables electrical conduction of the electrical appliance. When the control panel 20 rotates in a second direction, the power-connecting component 30 enables power disconnection of the electrical appliance. The adsorption component 40 is fixedly disposed on the inner wall of the housing 10, and the repulsion component 50 is disposed on one side of the adsorption component 40 and slides in cooperation with the inner wall of the housing 10. When the power is not interrupted, the adsorption component 40 is used to adsorb the repulsion component 50. When the power is interrupted, the adsorption component 40 is used to release the repulsion component 50. The repulsion component 50 moves to a predetermined position to provide a repulsive force to the control panel 20, thereby driving the control panel 20 to rotate in the second direction.

[0036] When an appliance needs to be turned on, the control panel 20 can be rotated in the first direction, and the power connection component 30 enables the appliance to conduct electricity, allowing it to operate on mains power. When an appliance needs to be turned off, the control panel 20 can be rotated in the second direction, opposite to the first direction, and the power connection component 30 enables the appliance to disconnect from power, stopping its operation. During a power outage, the adsorption component 40 releases the repulsion component 50, causing it to move to a predetermined position. The repulsion component 50 then applies a repulsive force to the control panel 20, driving it to rotate in the second direction, thus enabling the power connection component 30 to disconnect the appliance from power, thereby preventing the appliance from experiencing excessively high instantaneous voltage when power is suddenly restored, and avoiding damage to the appliance.

[0037] Please see Figure 1In one embodiment, the control panel 20 includes a pressure plate 201, one end of which is embedded inside the housing 10 and rotatably connected to the inner wall of the housing 10 via a rotating rod 205. The power connection assembly 30 includes a first conductive block 301 and two sets of second conductive blocks 302. The first conductive block 301 is fixedly disposed on the side wall of the pressure plate 201 located inside the housing 10. The two sets of second conductive blocks 302 are fixedly disposed on the inner wall of the housing 10 and distributed opposite to the first conductive block 301. One set of second conductive blocks 302 is connected to the mains power, and the other set of second conductive blocks 302 is connected to electrical appliances.

[0038] When it is necessary to turn on the appliance, the upper end of the pressure plate 201 can be pressed. At this time, the pressure plate 201 rotates in the first direction relative to the rotating rod 205, and the first conductive block 301 moves towards the inside of the housing 10 until the first conductive block 301 is simultaneously attached to one side of the two sets of second conductive blocks 302. At this time, the mains power can supply power to the appliance through the two sets of second conductive blocks 302 and the first conductive block 301. When it is necessary to turn off the appliance, the lower end of the pressure plate 201 can be pressed. At this time, the pressure plate 201 rotates in the second direction relative to the rotating rod 205, and the first conductive block 301 moves towards the outside of the housing 10. The first conductive block 301 disengages from the two sets of second conductive blocks 302, thereby realizing the power-off processing of the appliance.

[0039] Please see Figure 2 and Figure 3 In one embodiment, the repulsion component 50 includes a second slider 501 and a second permanent magnet 502 disposed on one side of the second slider 501. The second slider 501 is slidably engaged with the inner wall of the housing 10. The pressure plate 201 is disposed on one side inside the housing 10 with a third permanent magnet 504 that repels the second permanent magnet 502. The adsorption component 40 includes an electromagnet 401 and a first permanent magnet 402. The electromagnet 401 is fixedly disposed on the inner wall of the housing 10 and connected to the mains power. The first permanent magnet 402 is disposed on one side of the second slider 501 and can be adsorbed by the electromagnet 401.

[0040] When the power is on, the electromagnet 401 is connected to the mains power and generates magnetic attraction to attract the first permanent magnet 402, causing the second slider 501 to stay on one side of the electromagnet 401, and the second permanent magnet 502 and the third permanent magnet 503 to be misaligned. When the power is off, the electromagnet 401 loses its electromagnetic properties and releases the first permanent magnet 402. At this time, the second slider 501 moves away from the electromagnet 401, so as to move the second permanent magnet 502 to the side of the third permanent magnet 504. Through the repulsive force between the second permanent magnet 502 and the third permanent magnet 504, the pressure plate 201 is driven to rotate in the second direction, so that the first conductive block 301 is separated from the two sets of second conductive blocks 302, so as to ensure that the electrical appliances are not damaged due to excessive instantaneous voltage when the power is suddenly restored.

[0041] Please see Figure 3 In one embodiment, a second guide rail 101 is fixedly provided on the inner wall of the housing 10, and a second limiting block 102 is fixedly provided at one end of the second guide rail 101. The second slider 501 is slidably engaged with the second guide rail 101, and the second limiting block 102 and the second slider 501 are connected by a first elastic member 503. The first elastic member 503 is used to provide elastic tension to the second slider 501.

[0042] When the power is on, the electromagnet 401 is connected to the mains power and generates a magnetic attraction force to attract the first permanent magnet 402. At this time, the attraction force of the electromagnet 401 to the first permanent magnet 402 is greater than the elastic tension of the first elastic element 503, so that the first elastic element 503 is in a stretched state. When the power is off, the electromagnet 401 loses its electromagnetic property and releases the first permanent magnet 402. At this time, the first elastic element 503 provides an elastic tension force to the second slider 501 to drive the second slider 501 to move away from the electromagnet 401, so as to drive the second permanent magnet 502 to move to the side of the third permanent magnet 504, thereby providing a repulsive force to the third permanent magnet 504 and driving the pressure plate 201 to rotate in the second direction.

[0043] Please see Figure 1 In one embodiment, a second elastic element 60 is further provided inside the housing 10. One end of the second elastic element 60 is connected to the inner wall of the housing 10, and the other end is connected to the pressure plate 201, which is used to provide elastic support for the pressure plate 201 to maintain the stability of the pressure plate 201 after it rotates in the first direction or the second direction.

[0044] When the pressure plate 201 rotates in the first direction and the first conductive block 301 is attached to one side of the two sets of second conductive blocks 302, the second elastic member 60 provides support for the pressure plate 201, making the pressure plate 201 stable and ensuring that the first conductive block 301 is stably attached to one side of the two sets of second conductive blocks 302, thus ensuring the stability of the power supply to the electrical appliance. When the pressure plate 201 rotates in the second direction and the first conductive block 301 is detached from one side of the two sets of second conductive blocks 302, the second elastic member 60 provides support for the pressure plate 201, making the pressure plate 201 stable and ensuring that the first conductive block 301 and the two sets of second conductive blocks 302 are stably detached, thus ensuring the stability of the power outage of the electrical appliance.

[0045] Please see Figure 1 and Figure 2 In one embodiment, the pressure plate 201 is fixedly provided with a first guide rail 206 on one side inside the housing 10, a first limiting block 203 is fixedly provided at the end of the first guide rail 206, a first slider 204 is slidably provided on the first guide rail 206, and the end of the second elastic member 60 away from the inner wall of the housing 10 is connected to the first slider 204.

[0046] When the pressure plate 201 rotates in the first direction, the first slider 204 can slide from the beginning to the end of the first guide rail 206. During this process, the second elastic element 60 is gradually compressed until the first slider 204 passes the middle position of the first guide rail 206. Then, the second elastic element 60 extends, thereby providing support for the pressure plate 201 to maintain the stability of the pressure plate 201 after rotating in the first direction. When the pressure plate 201 rotates in the second direction, the first slider 204 can slide from the end to the beginning of the first guide rail 206. During this process, the second elastic element 60 is gradually compressed until the first slider 204 passes the middle position of the first guide rail 206. Then, the second elastic element 60 extends, thereby providing support for the pressure plate 201 to maintain the stability of the pressure plate 201 after rotating in the second direction.

[0047] In one embodiment, the first elastic element 503 and the second elastic element 60 can be springs or metal sheets, and there is no limitation here.

[0048] In this embodiment of the invention, when it is necessary to turn on the appliance, the control panel 20 can be rotated in the first direction, and the power connection component 30 enables the appliance to conduct electricity. At this time, the appliance is connected to the mains power and works. When it is necessary to turn off the appliance, the control panel 20 can be rotated in the second direction opposite to the first direction, and the power connection component 30 enables the appliance to disconnect from the power supply, and the appliance stops working. During a power outage, the adsorption component 40 can release the repulsion component 50, causing the repulsion component 50 to move to a predetermined position. Then, the repulsion component 50 applies a repulsive force to the control panel 20 to drive the control panel 20 to rotate in the second direction, so that the power connection component 30 enables the appliance to disconnect from the power supply. This avoids the appliance from being damaged by a sudden surge in voltage when power is restored. Compared with the prior art, this invention can automatically disconnect the connection between the appliance and the switch during a power outage, preventing damage to the appliance due to a surge in voltage when power is restored, thereby achieving power outage protection for the appliance.

[0049] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
