Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a power supply device and an air purifier. Background Technology

[0002] Currently, the power supply unit in ionization air purifiers typically includes a frame and multiple discharge plates housed within the frame. These discharge plates are connected to the power source via contacts. During long-term operation, users may clean the power supply unit or move the entire unit, potentially causing misalignment in the connection between the discharge plates and contacts. If the power supply unit is not installed securely, or if the discharge plates do not make proper contact with the contacts, arcing can occur, potentially leading to safety issues and affecting normal user operation. Furthermore, prolonged dust accumulation can cause the area around the contacts to become damp, also increasing the risk of arcing. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that the discharge plate in the prior art is connected to the power supply through contacts, which easily causes arcing. The present invention provides a power supply device and an air purifier.

[0004] To achieve the above objectives, embodiments of the present invention provide a power supply device, which includes: a first magnetic induction coil adapted to be connected to an AC power source; a second magnetic induction coil adapted to be connected to an electrode plate; the second magnetic induction coil adapted to be sleeved on the first magnetic induction coil, and a gap is provided between the first magnetic induction coil and the second magnetic induction coil.

[0005] Optionally, there may be multiple first magnetic induction coils, and multiple second magnetic induction coils, the number of which is equal to the number of first magnetic induction coils.

[0006] Optionally, the first ionization component further includes: a mounting component on which the first magnetic induction coil is disposed; the first magnetic induction coil is connected to the AC power supply via a wire.

[0007] Optionally, the mounting component further includes a cable tray formed on the mounting component; the cable tray is adapted to accommodate the wire.

[0008] Optionally, the power supply device further includes: an electrode frame, wherein the second magnetic induction coil is disposed on the top outer side of the electrode frame, and a plurality of electrodes are disposed at intervals on the inner side of the electrode frame.

[0009] Optionally, the electrode plate and the electrode plate frame are detachably connected.

[0010] Optionally, the power supply device further includes: a signal transmitter disposed within the first magnetic induction coil; and a signal receiver disposed within the second magnetic induction coil; the signal receiver being adapted to receive feedback signals emitted by the signal transmitter.

[0011] Optionally, the power supply device further includes: a signal converter disposed on the frame; the signal converter is communicatively connected to the signal receiver.

[0012] Optionally, the power supply device further includes: a rectifier disposed on the frame; the input end of the rectifier is connected to the second magnetic induction coil, and the output end of the rectifier is connected to the electrode plate.

[0013] This invention also provides an air purifier, characterized in that it includes: an electrode plate and a power supply device as described in any of the above embodiments connected to the electrode plate; the power supply device includes an electrode plate frame, a second magnetic induction coil is disposed on the top outer side of the electrode plate frame, and a plurality of the electrode plates are disposed at intervals on the inner side of the electrode plate frame.

[0014] This invention also provides an air purifier, which includes a power supply device as described in any of the above embodiments.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] 1. An embodiment of the present invention provides a power supply device, which includes: a first magnetic induction coil adapted to be connected to an AC power source; a second magnetic induction coil adapted to be connected to an electrode plate; the second magnetic induction coil adapted to be sleeved on the first magnetic induction coil, and a gap is provided between the first magnetic induction coil and the second magnetic induction coil.

[0017] With this configuration, when the power supply unit is operating, the first magnetic induction coil is connected to the AC power supply, generating an alternating magnetic field. This alternating magnetic field induces a voltage in the second magnetic induction coil, providing a high voltage for the plates in the second ionization component to operate normally. By replacing the existing technology where the plates are connected to the power supply via contacts with a connection via induction coils, the lack of contact between the first and second magnetic induction coils eliminates the possibility of misalignment and arcing, ensuring normal user operation. Furthermore, even after prolonged operation and significant dust accumulation, the electromagnetic induction between the first and second magnetic induction coils remains unaffected by humidity, preventing arcing.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Currently, the power supply unit in ionization air purifiers typically includes a frame and multiple discharge plates housed within the frame. These discharge plates are connected to the power source via contacts. During long-term operation, users may clean the power supply unit or move the entire unit, potentially causing misalignment between the discharge plates and contacts. If the power supply unit is not installed securely, or if the discharge plates and contacts do not make proper contact, arcing can occur, potentially leading to safety issues and affecting normal user operation. Furthermore, prolonged dust accumulation can cause the area around the contacts to become damp, also increasing the likelihood of arcing.

[0029] Therefore, the technical problem to be solved by the present invention is that the discharge plate in the prior art is connected to the power supply through contacts, which easily causes arcing. The present invention provides a power supply device and an air purifier.

[0030] like Figures 1 to 3 As shown, an embodiment of the present invention provides a power supply device, which includes a first ionization component and a second ionization component.

[0031] The first ionization component is provided with a first magnetic induction coil 1, which is adapted to be connected to an AC power source. The second ionization component includes a second magnetic induction coil 2 and an electrode plate 3 connected to the second magnetic induction coil 2. The second magnetic induction coil 2 is adapted to be sleeved on the first magnetic induction coil 1, and a gap is provided between the first magnetic induction coil 1 and the second magnetic induction coil 2.

[0032] When the second magnetic induction coil 2 is fitted onto the first magnetic induction coil 1, and a gap is maintained between the first magnetic induction coil 1 and the second magnetic induction coil 2, the first magnetic induction coil 1 and the second magnetic induction coil 2 form an induction coil with each other. When the power supply device is working, the first magnetic induction coil 1 is connected to an AC power source, which can be a 220V AC mains power grid or other high-frequency alternating voltages. This allows the first magnetic induction coil 1 to generate an alternating magnetic field. This alternating magnetic field induces a voltage in the second magnetic induction coil 2, thereby providing a high voltage for the normal operation of the electrode plate 3 in the second ionization component. Replacing the existing technology where the electrode plate 3 is connected to the power source via contacts with a technology where the electrode plate 3 is connected to the power source via an induction coil eliminates the possibility of misalignment between the first magnetic induction coil 1 and the second magnetic induction coil 2, preventing arcing and ensuring normal user operation. Furthermore, even after prolonged operation, with significant dust accumulation, the electromagnetic induction between the first magnetic induction coil 1 and the second magnetic induction coil 2 will not be affected by a humid environment, thus preventing arcing.

[0033] In this embodiment of the invention, the first magnetic induction coil 1 is composed of a first winding and a first magnetic core, and the second magnetic induction coil 2 is composed of a second winding and a second magnetic core. Specifically, those skilled in the art can wind different numbers of turns and select different magnetic cores or silicon steel sheets, etc., according to voltage requirements. Furthermore, the first magnetic induction coil 1 and the second magnetic induction coil 2 can use different conductor materials, magnetically conductive materials, and different winding methods. This embodiment is merely illustrative, and the specific materials of the conductor and magnetically conductive materials are not specifically limited, as long as the same technical effect is achieved.

[0034] Optionally, in one embodiment of the present invention, the first ionization component is provided with a plurality of first magnetic induction coils 1, and the second ionization component is provided with a number of second magnetic induction coils 2 corresponding to the number of first magnetic induction coils 1. This arrangement ensures that the number of first magnetic induction coils 1 and second magnetic induction coils 2 are matched, thereby maximizing the operating efficiency of the power supply device.

[0035] Optionally, in one embodiment of the present invention, the first ionization component further includes a mounting member 4, on which the first magnetic induction coil 1 is disposed, and the first magnetic induction coil 1 is connected to the AC power supply via a wire. The mounting member 4 also includes a wiring groove formed on the mounting member 4, the wiring groove being adapted to accommodate the wire. The mounting member 4 can be a single mounting plate or a hollow partition plate; those skilled in the art can modify it according to actual conditions. This embodiment is merely illustrative and not intended to limit the scope; any embodiment that achieves the same technical effect is acceptable.

[0036] Optionally, in one embodiment of the present invention, the second ionization component further includes an electrode frame 7, with the second magnetic induction coil 2 disposed on the top outer side of the electrode frame 7, and a plurality of electrode plates 3 disposed at intervals on the inner side of the electrode frame 7. Each electrode plate 3 is detachably connected to the electrode frame 7. Of course, other detachable fixing methods can also be used for connection, such as tongue-and-groove fitting, screw connection, or rivet connection. Those skilled in the art can modify these methods according to actual conditions. This embodiment is merely illustrative and not intended to limit the scope; any method that achieves the same technical effect is acceptable.

[0037] Optionally, in one embodiment of the present invention, the power supply device further includes a signal transmitter 5 and a signal receiver 6. The signal transmitter 5 is disposed within the first magnetic induction coil 1, and the signal receiver 6 is disposed within the second magnetic induction coil 2. The signal receiver 6 is adapted to receive feedback signals emitted by the signal transmitter 5. The power supply device also includes a signal converter, which is communicatively connected to the signal receiver 6.

[0038] The signal transmitter 5 can collect the induced magnetic field within the first magnetic induction coil 1 and the alternating voltage input to the first magnetic induction coil 1. After collecting the signal, the signal transmitter 5 can feed it back to the signal receiver 6. Upon receiving the feedback signal, the signal receiver 6 converts the feedback signal from an analog signal to a digital signal, and then transmits the digital signal to the controllers of each working module of the air purifier, thereby adjusting the working status of each working module. The signal transmitter 5 and the signal receiver 6 can be an infrared transmitter and receiver that work together. Of course, this embodiment is only an example and is not intended to limit the scope. Those skilled in the art can make changes according to actual conditions, as long as the same technical effect is achieved.

[0039] Optionally, in some embodiments of the present invention, the power supply device further includes a rectifier disposed on the frame, the input end of the rectifier being connected to the second magnetic induction coil 2, and the output end of the rectifier being connected to the pole plate 3.

[0040] Example 2

[0041] This invention also provides an air purifier, comprising: an electrode plate and a power supply device as described in any of the above embodiments connected to the electrode plate. The power supply device includes an electrode plate frame 7, a second magnetic induction coil is disposed on the top outer side of the electrode plate frame 7, and a plurality of electrode plates are spaced apart on the inner side of the electrode plate frame 7. A handle 8 is provided at the end of the electrode plate frame 7 away from the mounting member 4, allowing the user to easily pull out the entire electrode plate frame 7 for cleaning.

[0042] When the second magnetic induction coil 2 is placed on the first magnetic induction coil 1, and a gap is maintained between the first magnetic induction coil 1 and the second magnetic induction coil 2, the first magnetic induction coil 1 and the second magnetic induction coil 2 form an induction coil with each other.

[0043] When the power supply unit is working, the first magnetic induction coil 1 is connected to an AC power source, which can be a 220V AC mains power grid or other high-frequency voltages. This allows the first magnetic induction coil 1 to generate an alternating magnetic field. This alternating magnetic field induces a voltage in the second magnetic induction coil 2, thus providing a high voltage for the electrode plate 3 in the second ionization component to operate normally. Replacing the existing technology where the electrode plate 3 is connected to the power source via contacts with a technology where the electrode plate 3 is connected to the power source via an induction coil eliminates the possibility of misalignment between the first magnetic induction coil 1 and the second magnetic induction coil 2, preventing arcing and ensuring normal user operation. Furthermore, even after prolonged operation and significant dust accumulation, the electromagnetic induction between the first magnetic induction coil 1 and the second magnetic induction coil 2 will not be affected by a humid environment, thus preventing arcing in the air purifier.

[0044] Of course, those skilled in the art can also install this power supply device on other household appliances that are compatible with the power supply device. This embodiment is merely an example and is not intended to limit the application. As long as it can achieve the same technical effect, it is acceptable.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
