Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a switch control circuit and intelligent device. Background Technology

[0002] As living standards continue to improve, the types and functions of home smart devices are constantly expanding. Taking air purification equipment as an example, its main functions have shifted to formaldehyde removal and pet hair filtration, and it generally needs to be equipped with ultraviolet lamps for sterilization and disinfection.

[0003] According to safety regulations, air purification equipment equipped with ultraviolet (UV) lamps must prevent UV radiation leakage during installation, operation, maintenance, and cleaning. Therefore, each UV lamp needs to be equipped with at least two switches for control, ensuring that the UV lamp can smoothly stop emitting light in the aforementioned scenarios.

[0004] However, this increases the number of switches in the UV lamp control circuit, which not only increases product cost but also makes it more difficult to trigger the UV lamp. Utility Model Content

[0005] This application provides a switch control circuit and an intelligent device that can solve the problems existing in related technologies.

[0006] The technical solution is as follows: On the one hand, a switch control circuit is provided, which is suitable for the operation control of sterilization components. The switch control circuit includes: a first switch and a second switch. The sterilization component, the first switch, and the second switch are connected in series. The first switch is used to turn on when the consumables are installed in place, and the second switch is used to turn on when the movable door is closed.

[0007] The switch control circuit provided in this embodiment connects the sterilization component in series with a first switch and a second switch. The first switch is turned on after the consumables are installed in place, and the second switch is turned on when the movable door is closed. The sterilization component only needs two switches to achieve switch control, which not only meets the safety requirements of the ultraviolet lamp, but also reduces the number of switches. In addition, the first switch can also be used to detect whether the consumables are installed in place, and the second switch can also be used to detect whether the movable door is closed. This combines status detection and control functions, reduces the number of circuit interfaces and switches, and lowers product costs.

[0008] Intelligent devices such as air purifiers that use the switch control circuit of this embodiment do not require the installation of RFID modules on consumables such as filters, which helps to further reduce costs.

[0009] In some possible implementations, the switch control circuit further includes a control unit connected in series with the sterilization component, the first switch, and the second switch. The control unit is used to control the opening or closing of the sterilization component when the first switch and the second switch are simultaneously turned on.

[0010] Through the above arrangement, the first and second switches meet the safety control requirements of the ultraviolet lamp, and the control unit can control the working status of the ultraviolet lamp. For example, the control unit is associated with the switch of the smart device. After the smart device is turned on, the control unit controls the sterilization component to turn on, and after the smart device is turned off, the control unit controls the sterilization component to turn off.

[0011] In some possible implementations, the switch control circuit further includes a transition circuit board with a series circuit. The sterilization component, the first switch, and the second switch are electrically connected to the series circuit, such that the sterilization component, the first switch, and the second switch are connected in series.

[0012] With the above arrangement, the sterilization component, the first switch and the second switch are connected in series through the series circuit on the adapter circuit board. This not only reduces the difficulty of connecting the sterilization component, the first switch and the second switch in series, but also reduces the number and length of wires in the switch control circuit, thus reducing the wiring difficulty.

[0013] In some possible implementations, the adapter circuit board is provided with a first connector, a second connector, and a third connector, which are arranged in series on the series circuit. The first connector is electrically connected to the sterilization component, the second connector is connected to the first switch, and the third connector is connected to the second switch.

[0014] With the above arrangement, three connectors are arranged on the adapter circuit board, which are connected to the sterilization component, the first switch and the second switch respectively. This can reduce the difficulty of connecting the sterilization component, the first switch and the second switch to the adapter circuit board.

[0015] In some possible implementations, the adapter circuit board is further provided with a fourth connector, which is arranged in series on the series circuit and is electrically connected to the control unit.

[0016] With the above arrangement, the connection between the control unit and the adapter circuit board can be simplified by connecting the control unit to the fourth connector.

[0017] In some possible implementations, the sterilization component includes at least one ultraviolet lamp for irradiating the consumable to sterilize it.

[0018] In this embodiment, ultraviolet lamps can destroy the nucleic acid structure of microorganisms by emitting short-wave ultraviolet light of a specific wavelength, blocking the transmission and replication of their genetic information, and ultimately causing the microorganisms to become inactive or die, thereby achieving a sterilization effect.

[0019] In some possible implementations, there are multiple first switches and multiple consumables, with each first switch corresponding to one consumable. All of the first switches are connected in series with the sterilization component and the second switch.

[0020] With the above arrangement, when there are multiple consumables, each consumable corresponds to a first switch, and all the first switches are connected in series. The switch control circuit can only be turned on after all the consumables are installed in place, which has higher safety.

[0021] In some possible implementations, there are multiple ultraviolet lamps connected in parallel.

[0022] By using the above arrangement, multiple ultraviolet lamps can achieve a better and more comprehensive sterilization and disinfection effect.

[0023] In some possible implementations, the first switch and the second switch are at least one of a micro switch, a limit switch, a magnetic switch, and a Hall switch. The on / off control of the switch control circuit can be achieved using any of these switching devices.

[0024] On the other hand, a smart device is provided, which includes the switch control circuit described in this application and a sterilization component; The switch control circuit is used for switching the sterilization component on and off.

[0025] The smart device in this embodiment uses the switch control circuit of this application and has all the beneficial technical effects of this application.

[0026] In some possible implementations, the smart device is an air purification device, which includes consumables and a movable door. The consumables are filter elements. The first switch is located at the location of the filter element and can be turned on when the filter element is installed in place. The second switch is located at the location of the movable door and can be turned on when the movable door is closed.

[0027] With the above arrangement, the switch control circuit is applied to the air purification equipment. The first switch can realize the detection of the filter element's position and the on / off control of the sterilization component. The second switch can realize the detection of the closing of the movable door and the on / off control of the sterilization component. This realizes the combination of status detection and control functions, reduces the number of circuit interfaces and switches, and lowers product costs. Attached Figure Description

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0032] In the description of this application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0034] In related technologies, ultraviolet lamps are widely used in air purification equipment. However, since ultraviolet lamps cannot be directly exposed to the human body or eyes, the use of all ultraviolet lamps must meet safety regulations.

[0035] In the air purification equipment provided in the relevant technology, each ultraviolet lamp needs to be equipped with two switches to prevent a single switch from being accidentally touched. Moreover, since the ultraviolet lamp is usually arranged in the filter compartment of the air purification equipment, there is a risk of light leakage when the door of the filter compartment is opened. Therefore, another switch is arranged on the door. Thus, each ultraviolet lamp is controlled by three switches, and the ultraviolet lamp can only emit light when all three switches are turned on at the same time.

[0036] The large number of switches results in a complex and costly switching control circuit for the UV lamp. Furthermore, while the independent operation of the three switches improves safety, it also increases the difficulty of triggering the lamp; if one switch fails, the entire UV lamp will malfunction.

[0037] In addition, air purification equipment in related technologies usually assembles an RFID (Radio Frequency Identification) module on the filter element to realize the detection of consumable arrival, and an identification circuit needs to be arranged in the filter element compartment. When the RFID module is detected by the identification circuit, the arrival of the filter element can be realized.

[0038] Therefore, this application provides a switch control circuit that combines state detection and control functions, reduces the number of circuit interfaces and switches, and lowers product costs.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0040] On the one hand, combined with Figure 1 As shown, this embodiment provides a switch control circuit suitable for the operation control of the sterilization component 1. The switch control circuit includes: a first switch 2 and a second switch 3.

[0041] The sterilization component 1, the first switch 2, and the second switch 3 are connected in series. The first switch 2 is used to turn on when the consumables are installed in place, and the second switch 3 is used to turn on when the movable door is closed.

[0042] The switch control circuit provided in this embodiment connects the sterilization component 1 in series with the first switch 2 and the second switch 3. The first switch 2 is turned on after the consumables are installed in place, and the second switch 3 is turned on when the movable door is closed. The sterilization component 1 only needs two switches to achieve switch control, which not only meets the safety requirements of the ultraviolet lamp 11, but also reduces the number of switches. In addition, the first switch 2 can also be used to detect whether the consumables are installed in place, and the second switch 3 can also be used to detect whether the movable door is closed. This combines the status detection and control functions, reduces the number of circuit interfaces and switches, and lowers the product cost.

[0043] Intelligent devices such as air purifiers that use the switch control circuit of this embodiment do not require the installation of RFID modules on consumables such as filters, which helps to further reduce costs.

[0044] In some possible implementations, there are multiple ways to connect the sterilization component 1, the first switch 2, and the second switch 3. For example, the sterilization component 1, the first switch 2, and the second switch 3 can be connected in series, or the sterilization component 1, the second switch 3, and the first switch 2 can be connected in series, or the first switch 2, the sterilization component 1, and the second switch 3 can be connected in series, or the second switch 3, the sterilization component 1, and the first switch 2 can be connected in series.

[0045] Combination Figure 1 As shown, in some possible implementations, the switch control circuit also includes a control unit 4, which is connected in series with the sterilization component 1, the first switch 2, and the second switch 3. The control unit 4 is used to control the opening or closing of the sterilization component 1 when the first switch 2 and the second switch 3 are simultaneously turned on.

[0046] Through the above arrangement, the first switch 2 and the second switch 3 meet the safety control requirements of the ultraviolet lamp 11, and the control unit 4 can control the working status of the ultraviolet lamp 11. For example, the control unit 4 is associated with the switch of the smart device. After the smart device is turned on, the control unit 4 controls the sterilization component 1 to turn on. After the smart device is turned off, the control unit 4 controls the sterilization component 1 to turn off.

[0047] In some possible implementations, the control unit 4 is integrated onto an integrated circuit board.

[0048] Combination Figure 2As shown, in some possible implementations, the switch control circuit also includes a transition circuit board 5, which is provided with a series circuit 54. The sterilization component 1, the first switch 2, and the second switch 3 are electrically connected to the series circuit 54, so that the sterilization component 1, the first switch 2, and the second switch 3 are connected in series with each other.

[0049] With the above arrangement, the series connection circuit 54 on the adapter circuit board 5 realizes the series connection of the sterilization component 1, the first switch 2 and the second switch 3, which not only reduces the difficulty of connecting the sterilization component 1, the first switch 2 and the second switch 3, but also reduces the number and length of wires in the switch control circuit, thus reducing the wiring difficulty.

[0050] For example, the adapter circuit board 5 is a printed circuit board (PCB), a flexible printed circuit board (FPC), or a rigid-flex board.

[0051] Combination Figure 3 As shown, in some possible implementations, the adapter circuit board 5 is provided with a first connector 51, a second connector 52 and a third connector 53. The first connector 51, the second connector 52 and the third connector 53 are arranged in series on the series circuit 54. The first connector 51 is electrically connected to the sterilization component 1, the second connector 52 is connected to the first switch 2 and the third connector 53 is connected to the second switch 3.

[0052] With the above arrangement, three connectors are arranged on the adapter circuit board 5, which are connected to the sterilization component 1, the first switch 2, and the second switch 3 respectively. This can reduce the difficulty of connecting the sterilization component 1, the first switch 2, and the second switch 3 to the adapter circuit board 5.

[0053] Combination Figure 3 As shown, in some possible implementations, the adapter circuit board 5 is also provided with a fourth connector 55, which is arranged in series on the series circuit 54 and is electrically connected to the control unit 4.

[0054] With the above arrangement, the connection between the control unit 4 and the adapter circuit board 5 can be reduced by connecting the control unit 4 to the control unit 4 via the fourth connector 55.

[0055] Combination Figure 3 As shown, in some possible implementations, the sterilization component 1 includes at least one ultraviolet lamp 11, which is used to irradiate the consumables to sterilize and disinfect them.

[0056] In this embodiment, the ultraviolet lamp 11 can destroy the nucleic acid structure (DNA or RNA) of microorganisms (bacteria, viruses, fungi, etc.) by emitting short-wave ultraviolet light (UVC, wavelength 200-280nm), thereby blocking the transmission and replication of their genetic information, ultimately causing the microorganisms to become inactive (unable to reproduce) or die, thus achieving a sterilization effect.

[0057] The UV lamp 11 is suitable for sterilization and disinfection in smart devices such as air purifiers. Using ultraviolet light as a medium, it has a wider range of applications. Moreover, the penetrating power of ultraviolet light is extremely weak (it cannot penetrate paper, glass, or clothing), so it will not cause harm to people or pets outside the device.

[0058] Combination Figure 4 As shown, in some possible implementations, there are multiple first switches 2 and multiple consumables, with each first switch 2 corresponding to one consumable. All of the multiple first switches 2 are connected in series with the sterilization component 1 and the second switch 3.

[0059] With the above arrangement, when there are multiple consumables, each consumable corresponds to a first switch 2, and all the first switches 2 are connected in series. The switch control circuit can only be turned on after all the consumables are installed in place, which has higher safety.

[0060] Combination Figure 5 As shown, in some possible implementations, there are multiple ultraviolet lamps 11 connected in parallel.

[0061] With the above arrangement, the use of multiple ultraviolet lamps 11 can achieve a better and more comprehensive sterilization and disinfection effect.

[0062] For example, the consumable is a cylindrical filter element, and the ultraviolet lamp 11 is located inside the cylindrical filter element.

[0063] For example, each UV lamp 11 corresponds to one or more consumable arrangements.

[0064] In some possible implementations, the first switch 2 and the second switch 3 are at least one of a micro switch, a limit switch, a magnetic switch, or a Hall switch, and can also be sensors such as optical sensors or pressure sensors. The on / off control of the switch control circuit can be achieved using the above-mentioned switching devices.

[0065] On the other hand, an intelligent device is provided, which includes the switch control circuit of this application and the sterilization component 1; the switch control circuit is used for switching control of the sterilization component 1.

[0066] The smart device in this embodiment uses the switch control circuit of this application and has all the beneficial technical effects of this application.

[0067] In some possible implementations, the smart device is an air purification device, which includes consumables and a movable door. The consumables are filter elements. A first switch 2 is located at the location of the filter element and can be turned on when the filter element is installed in place. A second switch 3 is located at the location of the movable door and can be turned on when the movable door is closed.

[0068] With the above arrangement, the switch control circuit is applied to the air purification equipment. The first switch 2 can realize the detection of the filter element's position and the on / off control of the sterilization component 1. The second switch 3 can realize the detection of the closing of the movable door and the on / off control of the sterilization component 1. This realizes the combination of status detection and control functions, reduces the number of circuit interfaces and switches, and lowers product costs.
