Description

Technical Field

[0001] This application relates to the field of humidifier technology, specifically to a wireless humidifier. Background Technology

[0002] Humidifiers, a common household appliance used to increase the humidity of ambient air, have an atomizing plate as their core component. To ensure that the atomizing plate can work properly and produce sufficient water mist, the working surface of the atomizing plate must always be submerged at a suitable depth below the water surface; that is, the distance between the atomizing plate and the water surface must be controlled within a narrow and stable range.

[0003] To address this issue, most humidifiers on the market currently employ the following technical solution: the atomizing element is fixedly installed in a separate small water tank, which is located inside or connected to the main water tank. Then, a complex mechanical or electromechanical water supply mechanism continuously draws water from the main water tank into this fixed water tank to maintain a constant water level, ensuring the atomizing element remains in an effective working state. However, this approach makes thorough cleaning of the water tank impossible, leading to bacterial growth over time and compromising the humidifier's safety. Summary of the Invention

[0009] In some embodiments, the vertical distance between the upper surface of the float and the atomizing surface is less than 60 mm.

[0010] In some embodiments, the atomizing element has a closed receiving cavity, and the receiving coil is disposed within the receiving cavity to isolate the receiving coil from the liquid in the water tank.

The wireless humidifier also includes: A fan is disposed within the air cavity and is configured to drive airflow through the gap and out through the air outlet to carry the water mist generated by the atomizer assembly to the outside of the housing.

[0014] In some embodiments, a waterproof sealing structure is provided at the connection between the power supply column and the water tank.

[0015] The technical solution provided in this application can achieve the following beneficial effects: The wireless humidifier provided in this application has only a power supply column and an atomizer assembly inside the water tank, simplifying the internal structure of the water tank and making it easier for users to thoroughly clean the water tank.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0019] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and 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, and therefore should not be construed as a limitation on this application. In this application, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0021] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities at the point of connection are not connected through a transitional structure, but are simply linked together to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0022] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] Humidifiers, a common household appliance used to increase the humidity of ambient air, have an atomizing plate as their core component. To ensure that the atomizing plate can work properly and produce sufficient water mist, the working surface of the atomizing plate must always be submerged at a suitable depth below the water surface; that is, the distance between the atomizing plate and the water surface must be controlled within a narrow and stable range.

[0024] To address this issue, most humidifiers on the market currently employ the following technical solution: The atomizing element is fixedly installed in a small, independent water tank, which is located inside or connected to the main water tank. A complex mechanical or electromechanical water supply mechanism continuously draws water from the main tank into this fixed water tank to maintain a constant water level, ensuring the atomizing element remains in effective working condition. However, this approach makes thorough cleaning of the water tank impossible, leading to bacterial growth over time and compromising product safety.

[0025] To address the technical problems of complex internal structures and difficulty in thorough cleaning of water tanks in existing technologies, this application provides a wireless humidifier. This wireless humidifier simplifies the internal structure of the water tank while ensuring stable wireless power supply by configuring the atomizer assembly to float freely on the liquid surface and allowing the atomizer assembly to slide along a fixed power supply column.

[0026] Reference Figure 1 In some embodiments, the wireless humidifier includes a housing 100, which serves as the external support and decorative structure for the wireless humidifier. The outer contour of the housing 100 can be cylindrical, box-shaped, or other curved, depending on the actual installation space and aesthetic requirements.

[0027] Reference Figure 1In some examples, the wireless humidifier also includes a water tank 200. The water tank 200 is disposed within the housing 100 to hold humidifying water and to provide space for the atomizer assembly 400.

[0028] Reference Figure 2 and Figure 3 In some examples, the cordless humidifier also includes an atomizer assembly 400. The atomizer assembly 400 has a floating section that allows it to float freely with the liquid surface in the water tank 200.

[0029] Reference Figure 2 and Figure 3 In some examples, the cordless humidifier also includes a power supply column 300. The power supply column 300 is fixedly installed inside the water tank 200 and extends along the height of the water tank 200. Thus, the power supply column 300 provides a continuous guiding and power supply path to the atomizer assembly 400 as it floats with the water level, ensuring stable operation of the atomizer assembly 400 from high to low water levels. It should be noted that the cross-section of the power supply column 300 can be square, circular, or polygonal.

[0030] Reference Figures 2 to 4 In some examples, the bottom of the power supply column 300 is provided with a base, and the water tank 200 is provided with a mounting groove for engaging with the base. The base engages with the mounting groove to fix the position of the power supply column 300.

[0031] Reference Figure 2 and Figure 3 In some examples, the atomizer assembly 400 is sleeved on the outside of the power supply post 300 and slides with the power supply post 300 to allow the atomizer assembly 400 to move axially along the power supply post 300 and to restrict the radial movement of the atomizer assembly 400 relative to the power supply post 300. The power supply post 300 is configured to wirelessly power the sliding atomizer assembly 400.

[0032] Understandably, the water tank 200 only houses the power supply column 300 and the atomizer assembly 400, simplifying its internal structure and facilitating thorough cleaning by the user. Furthermore, the atomizer assembly 400 slides along the axial direction of the power supply column 300, guiding its movement and ensuring a stable alignment between the atomizer assembly 400 and the power supply column 300. This improves the stability of wireless transmission and prevents power interruptions or reduced efficiency caused by the atomizer assembly 400 shifting or deviating due to liquid level movement.

[0033] It should be noted that the power supply column 300 and the atomizer assembly 400 can achieve a sliding fit through methods such as guide rail and slide groove, shaft and bushing, or rib and groove. This application does not impose specific restrictions on the method of achieving a sliding fit between the power supply column 300 and the atomizer assembly 400, as long as axial sliding is free and radial movement is restricted.

[0034] Reference Figure 2 and Figure 4 In some embodiments, a waterproof sealing structure 900 may be provided at the connection between the power supply column 300 and the water tank 200.

[0035] It should be noted that this application does not impose specific limitations on the installation method of the waterproof sealing structure 900. For example, the waterproof sealing structure 900 can be a sealing ring fitted onto the power supply column 300, or it can be a waterproof adhesive or potting compound applied to the connection gap. The waterproof sealing structure 900 should be installed according to the actual assembly process and waterproof level requirements to ensure a reliable seal between the power supply column 300 and the water tank 200, preventing liquid from seeping into the electrical components below.

[0036] Reference Figure 2 and Figure 4 In some examples, the power supply column 300 can be connected to the bottom wall of the water tank 200, and a sealing structure is provided at the connection between the power supply column 300 and the bottom wall of the water tank 200. This facilitates the assembly of the power supply column 300 and the water tank 200 and prevents water from leaking from the bottom of the water tank 200.

[0037] Reference Figure 2 and Figure 4 In some examples, the power supply column 300 can be connected to the side wall of the water tank 200, and a sealing structure is provided at the connection between the power supply column 300 and the side wall of the water tank 200. This facilitates adaptation to different internal layouts of the water tank 200 and improves the space utilization of the water tank 200.

[0038] Reference Figures 5 to 7 In some embodiments, a transmitter coil 301 may be provided on the outer wall of the power supply column 300. A receiver coil 401 is provided on the atomizer assembly 400. The transmitter coil 301 and the receiver coil 401 are configured to wirelessly supply power to the atomizer assembly 400 through electromagnetic coupling between the power supply column 300 and the atomizer assembly 400 as the atomizer assembly 400 slides along the power supply column 300.

[0039] Understandably, as the atomizer assembly 400 slides along the power supply column 300, the receiving coil 401 obtains electrical energy through electromagnetic coupling with the transmitting coil 301 on the power supply column 300, thereby supplying power to the atomizer assembly 400. Thus, power is supplied via electromagnetic coupling between the transmitting coil 301 on the power supply column 300 and the receiving coil 401 on the atomizer assembly 400, achieving a contactless power supply connection. This avoids the risk of unstable electrical connections or leakage due to water surface fluctuations, improving the safety and reliability of the cordless humidifier.

[0040] It is also understandable that the transmitting coil 301 is wound around the outer periphery of the power supply column 300, and the amount of wire used depends on the diameter and axial height of the power supply column 300, and is independent of the overall size of the water tank 200. This allows the water tank 200 to be set to any size or shape as needed, without having to change the amount of wire used in the transmitting coil 301 to match the size of the water tank 200, thus avoiding an increase in the cost of the transmitting coil 301 due to an increase in the size of the water tank 200.

[0041] It should be noted that the transmitting coil 301 can be configured in two ways. One method involves the power supply column 300 consisting of two nested coaxial tubes. The transmitting coil 301 is wound along the axial direction of the tubes onto the outer wall of the inner tube or the inner wall of the outer tube, thus enclosing the transmitting coil 301 within a dry cavity formed by the outer and inner tubes, achieving waterproofing. Another method involves the power supply column 300 being a solid or hollow insulating column. The transmitting coil 301 is wound along the axial direction of the power supply column 300 onto its outer peripheral wall, and the transmitting coil 301 is sealed and protected by potting or coating with waterproof insulating varnish, thus achieving waterproofing.

[0042] Reference Figure 5 In some embodiments, the transmitting coil 301 may include a plurality of sub-transmitting coils arranged in parallel. The plurality of sub-transmitting coils are spaced apart along the axial direction of the power supply column 300. Each sub-transmitting coil has a switching device connected in series in its power supply branch. The switching device is configured to turn on or off the power supply branch of the corresponding sub-transmitting coil in response to electromagnetic induction between the corresponding sub-transmitting coil and the receiving coil 401.

[0043] Understandably, when the atomizer assembly 400 floats to a certain height, only the switching device on the sub-coil branch closest to the atomizer assembly 400 (i.e., with the strongest electromagnetic induction) is triggered and turned on, while other sub-coil branches farther away remain off due to weak induction. In this way, the power supply column 300 supplies power only to the effective working area, realizing on-demand energy distribution, thereby reducing standby power consumption and unnecessary heat generation.

[0044] It should be noted that the switching device can be a field-effect transistor, relay, thyristor, or other electronic switching element known in the art. This application does not impose specific limitations on the type of switching device. As long as the switching device can automatically control the conduction and cutoff of the power supply branch based on the energy or signal sensed by the sub-emitting coil of its branch, it is acceptable.

[0045] In some examples, the switching device may include a relay. The relay includes a drive coil and a set of contacts controlled by the drive coil. An induced current generated by the receiving coil 401 flows through the relay's drive coil when the sub-transmitter coil senses it. When the induced current is sufficiently large, the magnetic force generated by the drive coil attracts the contacts, automatically activating the power supply branch for the sub-transmitter coil and supplying power to the atomizer assembly 400. When the atomizer assembly 400 moves away and the induced current weakens, the magnetic force of the drive coil disappears, and the contacts automatically reset and disconnect under spring pressure, cutting off the power supply to that branch.

[0046] Reference Figure 5 In some examples, the lengths of multiple sub-emitter coils along the axial direction of the power supply column 300 are equal. This simplifies the winding method of the sub-emitter coils and makes operation convenient; in addition, it ensures that the area of ​​power supply remains consistent at different water levels, thereby ensuring that the atomizer assembly 400 obtains stable and balanced coupling energy at different heights.

[0047] Reference Figure 5 In some examples, the length of multiple sub-transmitter coils along the axial direction of the power supply column 300 gradually increases from top to bottom. This allows the lower sub-transmitter coils to have a larger area to compensate for transmission losses caused by water depth.

[0048] Reference Figure 5 In some examples, the length of multiple sub-emitter coils along the axial direction of the power supply column 300 gradually decreases from top to bottom. This facilitates matching the usage habit of longer dwell times of the atomizer assembly 400 when the water level is high, thereby further optimizing energy consumption distribution.

[0049] It should be noted that the above-mentioned method of supplying power to the atomizer assembly 400 through the power supply column 300 is not the only one.

[0050] In another embodiment, the transmitting coil 301 can also be a single long coil continuously wound along the axial direction of the power supply column 300. Simultaneously, the wireless humidifier can also be equipped with a control circuit that detects the real-time height of the atomizer assembly 400 using a position sensor (such as a Hall sensor) and controls the long coil to only energize a section corresponding to the position of the atomizer assembly 400. This ensures that the power supply column 300 supplies power only to the effective working area, achieving on-demand energy distribution and reducing standby power consumption and unnecessary heat generation.

[0051] Reference Figure 6 and Figure 7 In some embodiments, the atomizer assembly 400 may include an atomizing element 402 and a floater 403. The atomizing element 402 has an atomizing surface and is electrically connected to the receiving coil 401. The atomizing surface of the atomizing element 402 refers to the working surface used for immersing in water and breaking water into fine water mist through ultrasonic waves or other physical means. The floater 403 is connected to the atomizing element 402 and located above the atomizing surface, forming a floating part. The atomizing element 402, the receiving coil 401, and the floater 403 are integrated into a single floating body that can float with the water level.

[0052] Understandably, the atomizing element 402, the receiving coil 401, and the float 403 are integrated into a single floating body, achieving modular integration of the atomizer assembly 400. This allows the atomizing element 402, the receiving coil 401, and the float 403 to move synchronously, improving the accuracy and reliability of the water level tracking in the atomizer assembly 400; simultaneously, it facilitates the production, assembly, and maintenance of the atomizer assembly 400.

[0053] It should be noted that the atomizing element 402 can be a piezoelectric ceramic atomizing plate, an ultrasonic atomizing generator, or a heated atomizer; this application does not impose specific limitations on this. The type of atomizing element 402 should be selected based on the required atomization particle size, power consumption, and cost, ensuring that it can match the electrical energy received by the receiving coil 401. The floating element 403 can be a float, waterproof cotton, a hollow sealed container, or a low-density foam material, etc.; this application does not impose specific limitations on this. As long as the floating element 403 can provide buoyancy greater than its total weight for the integrated atomizer assembly 400 and has long-term physical and chemical stability to withstand water immersion, ensuring that the atomizer assembly 400 can float freely with changes in water level, it is acceptable.

[0054] Reference Figure 6 and Figure 7In some examples, the atomizing element 402 has a fixed shaft extending toward a side opposite to the atomizing surface, and the float element 403 is fixedly sleeved on the fixed shaft. In this way, the connection between the float element 403 and the atomizing element 402 can be ensured to be firm and the relative position can be kept unchanged, thereby maintaining the immersion depth of the atomizing surface of the atomizing element 402 relative to the float element 403 and improving the stability of the atomization effect.

[0055] Reference Figure 6 and Figure 7 In some embodiments, the atomizing element 402 has a closed receiving cavity 4021, and the receiving coil 401 is disposed within the receiving cavity 4021 to isolate the receiving coil 401 from the liquid in the water tank 200. This eliminates the need for additional wires to connect the atomizing element 402 and the receiving coil 401, thus simplifying the structure of the atomizer assembly 400 and consequently simplifying the internal structure of the water tank 200, facilitating thorough cleaning of the water tank 200. Simultaneously, by integrating the receiving coil 401 within the receiving cavity 4021 of the atomizing element 402, there is no need for an additional waterproof structure to encapsulate the receiving coil 401, thereby reducing the assembly difficulty and production cost of the atomizer assembly 400 and improving the overall compactness of the atomizer assembly 400.

[0056] Reference Figure 6 and Figure 7 In some examples, the receiving coil 401 is integrally connected with the atomizing element 402. This enhances the connection strength between the receiving coil 401 and the atomizing element 402, thereby improving the structural strength and electrical reliability of the atomizer assembly 400 under long-term water immersion conditions; at the same time, it simplifies the production and assembly process of the atomizer assembly 400 and improves production efficiency.

[0057] It should be noted that the receiving coil 401 and the atomizing element 402 can be molded using epoxy resin potting or silicone encapsulation to achieve an integral connection between the two; this application does not impose specific limitations on this. Based on manufacturing processes and waterproofing requirements, it is sufficient to ensure that the receiving coil 401 is completely sealed and protected, allowing for long-term immersion in water without damage.

[0058] Reference Figure 6 and Figure 7 In some examples, the atomizing element 402 may include a horizontal portion 4022 and a vertical portion 4023. The vertical portion 4023 forms the aforementioned fixed shaft for mounting the float element 403. The aforementioned receiving cavity 4021 is formed between the vertical portion 4023 and the horizontal portion 4022 for mounting the receiving coil 401, achieving a waterproof seal for the receiving coil 401. This facilitates providing both mechanical protection and a waterproof seal to the receiving coil 401, thereby simplifying the structure of the atomizer assembly 400.

[0059] Reference Figure 6 and Figure 7In some embodiments, the vertical distance between the upper surface of the float 403 and the atomizing surface is less than 60 mm.

[0060] Understandably, the vertical distance between the upper surface of the float 403 and the atomizing surface is less than 60mm, in order to avoid the distance between the two being too large, which would cause the atomizing component 402 to be too far from the liquid surface and thus fail to wet or reduce the atomization effect.

[0061] It should be noted that the vertical distance between the upper surface of the float 403 and the atomizing surface can be 10mm, 20mm, 30mm, 40mm, 50mm, or 60mm, which will not be listed here. As long as this distance ensures that the atomizing surface is always submerged to a suitable depth below the water surface within the normal fluctuation range of the water level, it falls within the protection scope of this application. In some examples, the vertical distance between the upper surface of the float 403 and the atomizing surface is 30mm.

[0062] Reference Figure 1 In some embodiments, the wireless humidifier may further include a base 500. The housing 100 is disposed on the base 500. Thus, the base 500 supports the housing 100, improving the overall stability of the wireless humidifier.

[0063] Reference Figure 1 , Figure 2 and Figure 3 In some examples, the water tank 200 is detachably mounted on the housing 100. The water tank 200 is located above the base 500. This allows the user to easily remove the water tank 200 for cleaning. It should be noted that the water tank 200 can be detachably connected to the housing 100 via a snap-fit ​​connection, threaded connection, or magnetic connection.

[0064] Reference Figure 1 , Figure 2 and Figure 3 In some other examples, the water tank 200 is detachably housed within the base 500. This achieves an integrated connection between the housing 100, the base 500, and the water tank 200, thereby improving the overall structural stability of the wireless humidifier. It should be noted that the water tank 200 can be detachably connected to the base 500 via snap-fit, threaded, or magnetic connections.

[0065] Reference Figure 2 , Figure 4 , Figure 8 and Figure 9 In some embodiments, the wireless humidifier may further include a first power supply interface 600. The first power supply interface 600 is disposed on the base 500 to connect to an external power source, thereby powering the entire wireless humidifier.

[0066] Reference Figure 2 , Figure 4 , Figure 8 and Figure 10 In some embodiments, the wireless humidifier may further include a second power supply interface 700. The second power supply interface 700 is disposed at the bottom of the water tank 200 and is detachably coupled to the first power supply interface 600 to transmit power from the base 500 to the power supply column 300 inside the water tank 200 when the water tank 200 is in place.

[0067] Reference Figure 2 , Figure 8 and Figure 9 In some embodiments, the first power supply interface 600 may include a base 500 coupler, and the second power supply interface 700 may include a water tank 200 coupler. The base 500 coupler and the water tank 200 coupler are plugged into each other. This allows for quick connection and disconnection of water and electricity, making operation convenient, safe, and reliable.

[0068] It should be noted that, referring to Figure 8 The base 500 coupler can be electrically connected to an external power source via the first circuit board 602 or a wire to introduce power. (See reference...) Figure 11 The water tank 200 coupler can also be electrically connected to the transmitter coil 301 on the power supply column 300 via the second circuit board 702 or a wire to transmit electrical energy to the transmitter coil 301.

[0069] Reference Figure 2 , Figure 4 and Figure 11 An air chamber 501 is formed inside the base 500, and an air outlet 101 communicating with the air chamber 501 is provided on the housing 100. The water tank 200 is located above the air chamber 501, and a gap 201 is formed between the side wall or bottom of the water tank 200 and the housing 100 to allow airflow. In this way, an air duct is formed around the periphery of the water tank 200, which can prevent airflow from interfering with the free floating of the atomizer assembly 400 inside the water tank 200, thereby improving the working reliability of the cordless humidifier. At the same time, by utilizing the air chamber 501 of the base 500, the air outlet 101 on the housing 100, and the gap 201 between the water tank 200 and the housing 100 to form this air duct, the internal space of the cordless humidifier is fully utilized, improving the overall structural compactness and internal space utilization of the cordless humidifier.

[0070] Reference Figure 2 , Figure 4 and Figure 11In some examples, the wireless humidifier also includes a fan 800. The fan 800 is disposed within the air chamber 501 and is configured to drive airflow through the gap 201 and out through the air outlet 101 to carry the water mist generated by the atomizer assembly 400 to the outside of the housing 100. The fan 800 can be driven by a motor. This achieves diffusion of water mist within the water tank 200, thereby improving the humidification efficiency and uniformity of the wireless humidifier.

[0071] It should be noted that the air cavity 501, the gap 201 and the air outlet 101 together form a continuous air duct to guide the airflow from the air cavity 501 around the gap 201 between the water tank 200 and the housing 100. When the airflow reaches the air outlet 101, it carries the water mist generated by the atomizer assembly 400 to the outside of the housing 100, thereby realizing the humidification function.

[0072] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solutions of the embodiments of this application should be included within the protection scope of the embodiments of this application.
