Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and in particular to a humidifier. Background Technology

[0002] Humidifiers are primarily used to regulate indoor air humidity and prevent dry air from causing discomfort to the human body. To ensure the normal operation of the humidifier, external power is input into the lower part and can be transmitted to the upper part (the spray structure) without electrical connection. Therefore, a circuit structure needs to be designed for the humidifier.

[0003] In the existing technology, as the functions of humidifiers increase, the circuit structure of humidifiers also becomes more complex, often requiring installation inside the water tank. This leads to inconvenience in circuit connection (such as the non-waterproof nature of mechanical and electrical connections). Utility Model Content

[0004] The purpose of this invention is to address the deficiencies in the aforementioned technology by providing a humidifier that improves the convenience of circuit connection and waterproofing when the circuit structure is installed inside the water tank.

[0007] In the above scheme, when current passes through the transmitting coil, a magnetic field is generated. This magnetic field passes through the magnetic component and affects the receiving coil. Specifically, when the current in the transmitting coil changes, the generated alternating magnetic field induces an electromotive force in the receiving coil, thereby generating a current. This achieves wireless power transmission between the first and second circuit structures without the need for wiring, making the connection between the parts of the humidifier containing the first and second circuit structures more convenient. Furthermore, the magnetic component is located simultaneously within the first enclosing space of the transmitting coil and the second enclosing space of the receiving coil. The transmitting and receiving coils share a single magnetic component, improving magnetic coupling efficiency and thus increasing power transmission efficiency.

[0017] In some embodiments, a threading hole is provided between the top plug and the top cover.

[0018] In some embodiments, a steam pipe is provided on the side of the top cover facing away from the water tank, one end of the steam pipe is connected to the water tank, and the other end of the steam pipe is provided with a nozzle, which has a spray nozzle.

[0019] The first circuit structure includes a light-emitting element, which is disposed inside the nozzle and adapted to project light onto the nozzle.

[0020] In some embodiments, a bottom plug is provided at the opening of the second receiving cavity, the bottom plug being used to confine the transmitting coil and the magnetic element within the second receiving cavity. Attached Figure Description

[0022] Figure 2 yes Figure 1 A cross-sectional structural diagram of a medium-sized humidifier;

[0023] Figure 3 yes Figure 2 A magnified schematic diagram of the local A structure;

[0024] Figure 4 This is a cross-sectional view of the transmitting coil provided in an embodiment of this application. Detailed Implementation

[0025] This application provides a humidifier comprising a first circuit structure and a second circuit structure. The second circuit structure is connected to a power source, which supplies power to the second circuit structure. Simultaneously, the second circuit structure supplies power to the first circuit structure via an electromagnetic induction coupling device. In this configuration, there is no fixed connection between the first and second circuit structures. This facilitates the connection between the second and first circuit structures when the second circuit structure needs to pass through a water tank to supply power to the first circuit structure. This solves the inconvenience of connection when the circuit structure needs to pass through a water tank in the prior art.

[0026] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case:

[0027] Depend on Figure 1 — Figure 4 As can be seen, this application provides a humidifier, which includes a transmitting coil 31, a magnetic element 32, and a receiving coil 33. The transmitting coil 31 is electrically connected to a second circuit structure 2 and includes a first enclosing space. At least a portion of the magnetic element 32 is located within the first enclosing space of the transmitting coil 31. The receiving coil 33 is electrically connected to the first circuit structure 1 and includes a second enclosing space, with at least a portion of the magnetic element 32 located within the second enclosing space.

[0028] In the above scheme, when current passes through the transmitting coil 31, a magnetic field is generated. This magnetic field passes through the magnetic component 32 and affects the receiving coil 33. Specifically, when the current in the transmitting coil 31 changes, the generated alternating magnetic field induces an electromotive force in the receiving coil 33, thereby generating a current. This achieves wireless power transmission between the first circuit structure 1 and the second circuit structure 2, eliminating the need for wiring and making the connection between the part of the humidifier containing the first circuit structure 1 and the part containing the second circuit structure 2 more convenient. In addition, the magnetic component 32 is located simultaneously within the first enclosing space of the transmitting coil 31 and the second enclosing space of the receiving coil 33. The transmitting coil 31 and the receiving coil 33 share a single magnetic component 32, improving the magnetic coupling efficiency and thus improving the power transmission efficiency.

[0029] In some examples, the second circuit structure 2 can be located below the water tank 5. The second circuit structure 2 may include the atomizing components of a humidifier and a fan, etc. The atomizing components turn the water in the water tank 5 into water mist, and the fan then discharges the water mist into the air to achieve the purpose of regulating air humidity. The second circuit structure 2 can be connected to a power source to supply power to it.

[0030] It should be understood that power sources include batteries, power banks, and household power supplies.

[0031] The first circuit structure 1 can be positioned above the water tank 5. The first circuit structure 1 may include a lighting component, a sound component, and control buttons for the humidifier. Since the second circuit structure 2 is already connected to a power source, it needs to be electrically connected to the first circuit structure 1 to supply power. In this embodiment, the transmitting coil, magnetic component, and receiving coil form an electromagnetic induction coupling device 3, which electrically connects the second circuit structure 2 to the first circuit structure 1. The working principle of the electromagnetic induction coupling device 3 is as follows: when the current in a circuit changes, it generates a changing magnetic field. This changing magnetic field passes through adjacent circuits and, according to Faraday's law of electromagnetic induction, induces an electromotive force (voltage) in the second circuit, thereby generating a current.

[0032] In some examples, the transmitting coil 31 can be a helical coil structure made of materials such as copper or aluminum. The cross-sectional shape of the transmitting coil 31 can be circular, square, triangular, etc. It should be noted that... (See also...) Figure 4 Taking a transmitting coil 31 with a circular cross-section as an example, a circular hole is formed inside the transmitting coil 31. Within the height range of the transmitting coil 31, the area of ​​this circular hole is the first enclosing space, such as... Figure 4The area B shown by the dashed line is the first enclosing space of the transmitting coil 31. It should be understood that the meaning of the second enclosing space of the receiving coil 33 is the same as the meaning of the first enclosing space of the transmitting coil 31.

[0033] In some examples, the magnetic component 32 may be a material with high magnetic permeability, such as ferrite, iron-magnesium alloy, or iron-nickel alloy.

[0034] In some examples, the magnetic component 32 can be a hollow cylindrical structure. This structure improves the symmetry and stability of the magnetic field distribution. Because the magnetic field distribution of a hollow cylindrical permanent magnet is symmetrical, it depends only on the distance from the central axis and is independent of the angle. This characteristic makes the magnetic field distribution uniform and stable, which is beneficial for improving the efficiency and stability of electromagnetic coupling. Furthermore, it provides good shielding. Due to the closed shape of the hollow cylindrical structure, it effectively shields against electromagnetic interference (EMI), helping to reduce interference from external electromagnetic fields to the internal circuitry and improve system stability.

[0035] In other examples, the magnetic element 32 can be a solid elongated structure with cross-sectional shapes such as square or triangular sections.

[0036] In some examples, at least a portion of the magnetic element 32 is located within the first enclosing space of the transmitting coil 31, and at least a portion of the magnetic element 32 is also located within the second enclosing space of the receiving coil 33. It is possible that both ends of the magnetic element 32 are located within the first and second enclosing spaces respectively; or it is possible that the entire magnetic element 32 is located simultaneously within both the first and second enclosing spaces. The transmitting coil 31 and the receiving coil 33 share a single magnetic element 32, which on the one hand reduces the length and complexity of the magnetic circuit, thereby reducing magnetic resistance and improving the transmission efficiency of magnetic flux; on the other hand, it simplifies the overall design, reduces the number and complexity of components, makes the overall structure more compact, and reduces the size of the electromagnetic induction coupling device 3.

[0037] In some embodiments, at least a portion of the transmitting coil 31 is located within a first enclosing space of the receiving coil 33. This arrangement further reduces the size of the electromagnetic induction coupling device 3 and improves the compactness of the structure.

[0038] In some examples, a portion of the length of the transmitting coil 31 is located within the first enclosing space of the receiving coil 33.

[0039] In other examples, the entire length of the transmitting coil 31 is located within the first enclosing space of the receiving coil 33.

[0040] In some embodiments, the receiving coil 33 is connected to the first circuit structure 1 via a receiving adapter plate 34, and the transmitting coil 31 is connected to the second circuit structure 2 via a transmitting adapter plate 35. Connecting the receiving coil 33 to the first circuit structure 1 via the receiving adapter plate 34 facilitates this connection. Similarly, connecting the transmitting coil 31 to the second circuit structure 2 via the transmitting adapter plate 35 also facilitates this connection.

[0041] In some examples, the receiver adapter 34 includes a first connector 341, which may be a quick-connect connector. The receiver adapter 34 is quickly connected to the first circuit structure 1 via the first connector 341. The two ends of the wires in the receiving coil 33 are connected to the first connector 341.

[0042] In some examples, the transmitter adapter board 35 includes a second connector 351, which may be a quick-connect connector. The transmitter adapter board 35 is quickly connected to the second circuit structure 2 via the second connector 351. The two ends of the wires in the transmitter coil 31 are connected to the second connector 351.

[0043] In some embodiments, the humidifier further includes a bottom shell 4, a water tank 5, and a top cover 6. The top cover 6 is adapted to seal the water tank 5, and the bottom shell 4 is adapted to accommodate the water tank 5. The water tank 5 and the top cover 6 are provided with a first protrusion 61 and a second protrusion 51 facing each other. The first protrusion 61 is located on the top cover 6, and the second protrusion 51 is located on the water tank 5. A transmitting coil 31 and a magnetic element 32 are located on the second protrusion 51, and a receiving coil 33 is located on the first protrusion 61. By placing the receiving coil 33 on the first protrusion 61 of the top cover 6 and the transmitting coil 31 and the magnetic element 32 on the second protrusion 51 of the water tank 5, opening the top cover 6 will not affect the connection of the first circuit structure 1 and the second circuit structure 2, facilitating the addition of water to the water tank 5 by opening the top cover 6 and improving the flexibility of the structure.

[0044] In some examples, the top cover 6 is used to seal the water tank 5, which is located inside the bottom shell 4. A second circuit structure 2 is provided between the water tank 5 and the bottom shell 4. The second circuit structure 2 may include an atomizer, a fan, a speaker, etc.

[0045] In some specific examples, the first protrusion 61 includes a first cavity 611, within which a third protrusion 62 is provided. A receiving gap is provided between the third protrusion 62 and the cavity wall of the first cavity 611. The third protrusion 62 has a first receiving cavity 621 with one open end, adapted to receive the second protrusion 51. The second protrusion 51 has a second receiving cavity 511 with one open end, the opening of which faces away from the upper cover 6. A transmitting coil 31 is disposed within the second receiving cavity 511, and at least a portion of the magnetic element 32 is located within the second enclosing space of the transmitting coil 31. A receiving coil 33 is disposed within the receiving gap.

[0046] In some examples, the transmitting coil 31 can be sleeved on the outer side of the third protrusion in the radial direction, and can be in close contact with the third protrusion or at a certain gap.

[0047] Since the transmitting coil 31 and the magnetic element 32 are located on the second protrusion 51, and the second protrusion 51 is located in the first receiving cavity 621 of the third protrusion 62, and the receiving coil 33 is located in the receiving gap between the third protrusion 62 and the cavity wall of the first receiving cavity 621, the receiving coil 33 is located on the outer side of the transmitting coil 31 and the magnetic element 32 in the radial direction, making the structure of the electromagnetic induction coupling device 3 more compact.

[0048] In some examples, the length of the transmitting coil 31 may be the same as that of the receiving coil 33.

[0049] In other examples, the length of the transmitting coil 31 is greater than the length of the receiving coil 33.

[0050] In some examples, one end of the transmitting coil 31 is located within the second enclosing space.

[0051] In other examples, the two ends of the transmitting coil 31 are located outside the second enclosing space, and a portion between the two ends of the transmitting coil 31 is located inside the second enclosing space.

[0052] In some embodiments, a receiving adapter plate 34 is provided inside the first cavity 611, and a top plug 7 is provided above the first cavity 611. Part of the top plug 7 is embedded inside the first cavity 611 to limit the receiving coil 33. By limiting the receiving coil 33 inside the first cavity 611 with the top plug 7, the receiving coil 33 is prevented from moving, thereby improving the stability of power reception.

[0053] In some examples, the top plug 7 abuts against one end of the receiving coil 33, and the other end of the receiving limit abuts against the bottom of the first cavity 611, thus limiting the receiving coil 33 within the first cavity 611.

[0054] In other examples, the top plug 7 wraps around the radially outer surface of the receiving coil 33, confining the receiving coil 33 within the first cavity 611.

[0055] In some other examples, the top plug 7 includes the radially outer surface of the receiving coil 33 while abutting against one end of the receiving coil 33, thus limiting the receiving coil 33.

[0056] In some examples, the top plug 7 is made of a flexible material.

[0057] In some embodiments, a wire hole 63 is provided between the top plug 7 and the top cover 6. The first circuit structure 1 can be connected to the first cavity 611 through the wire hole 63 and connected to the receiving adapter plate 34. By providing the wire hole 63, the convenience of circuit connection is improved.

[0058] In some examples, the thread hole 63 may be provided on the top cover 6.

[0059] In other examples, the thread hole 63 can be set with the top plug 7.

[0060] In some implementations, see Figure 2 The top cover 6 has a steam pipe 9 on the side facing away from the water tank 5. One end of the steam pipe 9 is connected to the water tank 5, and the other end of the steam pipe 9 has a nozzle 10 with a nozzle opening 101. The first circuit structure 1 includes a light-emitting element, which is located inside the nozzle 10 and is adapted to project light into the nozzle opening. By setting the light-emitting element inside the nozzle 10 and projecting light into the nozzle opening 101 through the light-emitting element, when the water mist is discharged outward through the nozzle, the light is projected into the water mist, making the water mist appear in a color corresponding to the color of the light, thus enhancing the atmosphere.

[0061] In some examples, steam pipe 9 is connected to water tank 5, through which water mist in water tank 5 is discharged.

[0062] In some examples, the light-emitting element is located on the side of the steam pipe closer to the nozzle.

[0063] In some embodiments, a bottom plug 8 is provided at the opening of the second receiving cavity 511. The bottom plug 8 is used to confine the transmitting coil 31 and the magnetic element 32 within the second receiving cavity 511. By confining the transmitting coil 31 and the magnetic element 32 within the second receiving cavity 511 by the bottom plug 8, the transmitting coil 31 and the magnetic element 32 are prevented from shaking, thereby improving the stability of power transmission.

[0064] In some examples, the bottom plug 8 is made of an elastic material such as rubber.

[0065] In some examples, the bottom plug 8 also limits the transmitter adapter plate 35 to prevent it from shaking and improve the stability of the circuit connection.
