Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an electromagnetic heating humidifier. Background Technology

[0002] Electromagnetically heated atomizers or humidifiers are devices that use the principle of electromagnetic induction to convert electrical energy into heat energy, thereby atomizing liquids. In existing electromagnetic heating humidifiers, the liquid storage tank is a fixed structure or integrated with the main structure, making disassembly and cleaning extremely inconvenient. After prolonged use, scale and stains accumulate on the inner wall of the storage tank. The scale (mainly composed of calcium carbonate and magnesium carbonate) is a poor conductor of heat, hindering heat transfer, reducing heating efficiency, and increasing energy consumption. This not only affects equipment performance but may also pose health hazards and safety risks.

[0003] While existing technologies offer designs for detachable water tanks, they generally suffer from insufficient control over the risk of dry-burning. Because the storage tank is designed as a detachable, independent unit, traditional water level detection devices are difficult to install and use effectively. For example, infrared sensors cannot penetrate the magnetically permeable material of the tank wall; float-type sensors experience a significant drop in accuracy when the liquid boils; and contact-type water level sensors face stability issues related to power supply and signal transmission. These technological limitations prevent detachable water tanks from achieving reliable water level monitoring in practical use, increasing the risk of dry-burning damage and safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetically heated humidifier to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides an electromagnetically heated humidifier, comprising:

[0007] The housing has a central receiving box with an open top and a microcrystalline panel at the bottom center. The bottom of the receiving box has several lifting feet and connecting feet.

[0008] An electromagnetic heating assembly is disposed inside the housing and located below the receiving box. The electromagnetic heating assembly has a connecting plate, a coil disk, and a circuit board. The coil disk and the connecting plate are respectively suspended and fixed by the lifting feet. The coil disk is located between the microcrystalline panel and the connecting plate. The circuit board is fixed to the lower side of the connecting plate.

[0009] The water tank is made of magnetic material or has a magnetic sheet at the bottom. The water tank is detachably installed in the container. The top of the water tank is provided with a cover plate, and the cover plate is provided with a steam vent.

[0010] A base plate is located at the bottom of the housing. A connecting post is provided on the base plate corresponding to the connecting foot position. The weight of the humidifier is applied to the base plate by docking and fixing the connecting post and the connecting foot. The base plate is provided with a weighing sensor, which is electrically connected to the circuit board. The elastic sensing end of the weighing sensor is located on the lower side of the base plate and is used to contact the platform or the ground.

[0011] In this technical solution, when the water tank is placed into the container, its bottom contacts the microcrystalline panel to form a closed magnetic circuit. The electromagnetic heating component is suspended and fixed by the lifting feet, avoiding mechanical stress from affecting the stability of the circuit board. The rigid connection between the connecting feet and the base plate connecting column concentrates the weight of the equipment onto the base plate. The elastic sensing end of the load cell preferentially contacts the bearing surface, and the water level is determined by measuring the change in vertical pressure. In some specific embodiments, the load cell can be preset to a baseline when the humidifier is empty or has a small amount of water in the tank. When the weight change is lower than the preset baseline during operation, a dry-burning warning signal is generated to alert of the risk of dry burning.

[0012] Compared to existing technologies, current solutions cannot effectively integrate liquid level sensors into detachable water tanks, requiring fixed structures or complex power supply schemes. This embodiment separates the weight transfer path of the water tank from the electromagnetic heating component through structural reconstruction, using a weighing sensor to indirectly monitor water volume, avoiding signal interference from magnetic materials, and solving the compatibility problem between detachable water tanks and electromagnetic heating.

[0013] This technical solution achieves a balance between the convenient cleaning of the detachable water tank and the efficiency of electromagnetic heating. It avoids sensor installation limitations through indirect weight detection, and the rigid connection structure ensures the accuracy of pressure measurement, effectively reducing the risk of dry burning.

[0014] As an extension of the above solution, at least three load cells are provided, and the load cells are distributed in a circular array around the center of the base plate. The load cells can be implemented using resistance strain gauge sensors or piezoelectric sensors. The circular array distribution means that multiple sensors are arranged at equal angular intervals around the center point of the base plate. This distribution forms a symmetrical support structure, which can offset the measurement error caused by eccentric loads.

[0015] As an extension of the above solution, the lower side of the base plate is provided with a support foot, and the height of the support foot protruding from the lower side of the base plate is less than the height of the elastic sensing end protruding from the lower side of the base plate.

[0016] When the humidifier is placed on a platform or the ground, the elastomer sensing end first contacts the bearing surface and bears the main pressure. At this time, the load cell is in effective working condition and can accurately detect changes in the weight of the water tank. The support feet, due to their lower height, form a gap with the bearing surface after the elastomer sensing end is compressed, providing auxiliary support only when the equipment is subjected to additional impacts or overloads. Through the height difference between the elastomer sensing end and the support feet, the weight of the equipment and the water tank are transmitted to the load cell via the elastomer sensing end, while the support feet only bear the mechanical load under extreme conditions, preventing the elastomer from undergoing plastic deformation or failure due to long-term pressure.

[0017] As an extension of the above solution, a cooling fan is provided at the center of the base plate. The cooling fan accelerates the transfer of heat from the electromagnetic heating components and circuit board to the external environment through active airflow circulation, preventing heat from accumulating at the bottom of the housing and causing component aging or performance degradation.

[0018] As an extension of the above solution, the top of the water tank is provided with an opening, the edge of the opening is bent outward to form a support edge, and the shell has a support ring protruding upward at the open edge of the top of the container, and the support edge overlaps the support ring.

[0019] In this extended design, the annular contact area between the support edge and the support ring on the bearing surface ensures even weight distribution of the water tank. During disassembly, the lockless design between the support edge and the support ring allows the water tank to be lifted vertically without rotation or unlocking. This enables tool-free, rapid assembly and disassembly of the water tank from the shell. The surface contact between the support edge and the support ring effectively reduces local pressure, preventing liquid leakage caused by tank deformation.

[0020] As an extension of the above solution, the water tank includes a connecting ring body, the inner side of which is provided with a lower ring groove and an upper ring groove, the supporting edge of the water tank is embedded in the lower ring groove, and the outer edge of the cover plate is embedded in the upper ring groove.

[0021] In this extended solution, when the water tank is installed onto the shell support ring, the lower part of the connecting ring acts as an intermediate load-bearing component to evenly transfer the weight of the water tank to the support ring, avoiding local stress concentration that could lead to structural deformation, while also preventing steam from unexpectedly escaping from the edge of the cover plate.

[0022] As an extension of the above solution, the housing has a top cover, with a fastening element on the inner side of the top cover and a fastening position on the outer side of the support ring. The top cover presses the connecting ring, the support edge of the water tank, and the outer edge of the cover plate onto the support ring through the engagement of the fastening element and the fastening position. In this extended solution, the fastening element and the fastening position cause the vertical pressure generated by the top cover to press the connecting ring, the support edge, and the outer edge of the cover plate onto the support ring, forming a continuous sealing interface to prevent steam leakage from the outer edge of the cover plate or the assembly gap between the cover plate and the water tank.

[0023] As an extension of the above solution, the housing is recessed on the outer side of the support ring to form a groove, which is symmetrically arranged on both sides of the support ring. When installing or removing the water tank, the recessed area formed by the groove can accommodate fingers or tools, avoiding slippage caused by the excessive smoothness of the outer surface of the support ring during operation, and reducing the risk of slippage due to improper force application.

[0024] As an extension of the above solution, the lower side of the cover plate is provided with several protrusions. The protrusions can improve the structural strength of the cover plate, making it less prone to deformation or denting when subjected to steam pressure for a long time. In addition, water droplets condense on the protrusions during the steam rise process, which can guide the condensate backflow.

[0025] As an extension of the above solution, the upper cover has a through hole corresponding to the steam port of the cover plate. The steam port is located at the center of the cover plate. The steam port is provided with a steam bottom cover and a steam top cover. The outer side of the steam bottom cover is embedded in the steam port. The steam top cover is pressed onto the steam bottom cover by the upper cover. The steam top cover has a circular hole in the center. The steam bottom cover has a plurality of arc-shaped holes arranged in a circular array around the circular hole. The arc-shaped holes are staggered from the circular holes.

[0026] In this extended design, the arc-shaped holes and round holes are staggered, allowing the steam to first enter through the arc-shaped holes, then converge towards the center between the bottom and top steam covers, and finally spray upwards from the round holes. This steam flow path causes liquid droplets in the steam to adhere to the wall they flow through and then flow back, while the dry steam is discharged upwards through the round holes. Simultaneously, the staggered arrangement of the arc-shaped and round holes prevents foreign objects from directly entering the channel and can intercept solid particles. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0036] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figures 1 to 3The following are several embodiments of an electromagnetically heated humidifier according to the present invention.

[0040] like Figures 1 to 3 As shown, in some embodiments, an electromagnetically heated humidifier includes:

[0041] The housing 100 has a housing 110 in the middle. The top of the housing 110 is open, and the bottom center has a microcrystalline panel 120. The bottom of the housing 110 has several lifting feet 130 and connecting feet 140. The microcrystalline panel 120 refers to a high-temperature resistant non-metallic magnetic plate located at the bottom of the housing 110. It can be made of microcrystalline glass material and is used to isolate the electromagnetic heating component from direct contact with the water tank while transmitting electromagnetic energy.

[0042] An electromagnetic heating assembly 200 is disposed within the housing 100 and located below the receiving box 110. The electromagnetic heating assembly includes a connecting plate 210, a coil disk 220, and a circuit board 230. The coil disk 220 and the connecting plate 210 are respectively suspended and fixed by the lifting feet 130. The coil disk 220 is located between the microcrystalline panel 120 and the connecting plate 210. The circuit board 230 is fixed to the lower side of the connecting plate 210. Those skilled in the art will understand that the coil disk (excitation coil) is used to generate an alternating magnetic field. When high-frequency alternating current passes through the coil disk, a rapidly changing alternating magnetic field is generated around the coil. When the magnetic field passes through a metal conductor, eddy currents are induced inside the conductor, and the eddy currents generate heat to achieve heating. The circuit board is responsible for coordinating the operation of each component and adjusting parameters such as heating power, frequency, and time to achieve intelligent control. This utility model does not impose any limitations on the principle and function of electromagnetic heating of the electromagnetic heating assembly. Those skilled in the art can set it according to existing technology and actual usage requirements, which will not be elaborated upon here.

[0043] The water tank 300 is made of magnetic material or has a magnetic sheet at the bottom. The water tank 300 is detachably installed in the container 110. The top of the water tank 300 is provided with a cover plate 310, and the cover plate 310 is provided with a steam port 320.

[0044] A base plate 400 is located at the bottom of the housing 100. A connecting post 410 is provided on the base plate 400 corresponding to the connecting foot 140. The weight of the humidifier is applied to the base plate 400 by the connection post 410 and the connecting foot 140. The base plate 400 is provided with a load cell 420, which is electrically connected to the circuit board 230. The elastic sensing end of the load cell 420 is located on the lower side of the base plate 400 and is used to contact the platform or the ground. The load cell is a pressure sensing element integrated on the base plate, used to detect the load-bearing capacity of the base plate. Specifically, a strain gauge sensor can be used, with its elastic sensing end extending to the lower side of the base plate. The remaining water volume in the water tank is indirectly calculated by measuring the overall weight change.

[0045] In this embodiment, when the water tank is placed into the container, its bottom contacts the microcrystalline panel to form a closed magnetic circuit. The electromagnetic heating component is suspended and fixed by the lifting feet, avoiding mechanical stress from affecting the stability of the circuit board. The rigid connection between the connecting feet and the base plate connecting column concentrates the weight of the device onto the base plate. The elastic sensing end of the load cell preferentially contacts the bearing surface, and the water level is determined by measuring the change in vertical pressure. In some specific embodiments, the load cell can be preset to a baseline when the humidifier is empty or has a small amount of water in the tank. When the weight change is lower than the preset baseline during operation, a dry-burning warning signal is generated to alert of the risk of dry burning.

[0046] Compared to existing technologies, current solutions cannot effectively integrate liquid level sensors into detachable water tanks, requiring fixed structures or complex power supply schemes. This embodiment separates the weight transfer path of the water tank from the electromagnetic heating component through structural reconstruction, using a weighing sensor to indirectly monitor water volume, thus avoiding signal interference from magnetic materials. The rigid connection design of the base plate eliminates the impact of mechanical stress on the circuitry, and the suspension structure ensures the operational stability of the electromagnetic component, resolving the compatibility issue between the detachable water tank and electromagnetic heating. This embodiment achieves a balance between convenient cleaning of the detachable water tank and electromagnetic heating efficiency, avoids sensor installation limitations through indirect weight detection, ensures pressure measurement accuracy through a rigid connection structure, and effectively reduces the risk of dry burning.

[0047] like Figure 3 As shown, in some embodiments, at least three load cells 420 are provided, and the load cells 420 are distributed in a circular array around the center of the base plate 400. The load cells can be implemented using resistance strain gauge sensors or piezoelectric sensors, which generate electrical signal changes through the deformation of an elastic body. The circular array distribution means that multiple sensors are arranged at equal angular intervals around the center point of the base plate; specifically, an equilateral triangle or square layout can be used. In some specific embodiments, such as... Figure 3As shown, four load cells are configured, forming a symmetrical support structure that can compensate for measurement errors caused by eccentric loads. Those skilled in the art will understand that the number of load cells can be adjusted to five, six, or other different quantities depending on actual usage requirements.

[0048] In this embodiment, when the water tank is placed inside the container, its weight is transmitted to the base plate through connecting columns and connecting feet. Three or more symmetrically distributed load cells form a planar support system, and the pressure value detected by each sensor is weighted and calculated via a circuit board. When the water tank shifts laterally, the circumferentially arrayed sensor group automatically balances the pressure differences at each point, eliminating measurement errors caused by installation position deviations. For example, in an equilateral triangle layout, the angle between any two sensors and the center of the base plate is 120 degrees, effectively capturing the force distribution in three-dimensional space, ensuring accurate calculation of the total weight, precisely obtaining the water level in the tank, and effectively avoiding the risk of dry burning due to misjudgment of the liquid level.

[0049] like Figure 3 As shown, in some embodiments, the lower side of the base plate 400 is provided with a support foot 430. The support foot 430 refers to a mechanical support structure provided on the lower side of the base plate, which is used to provide auxiliary support when the equipment is placed. The height of the support foot 430 protruding from the lower side of the base plate 400 is less than the height of the elastic sensing end protruding from the lower side of the base plate 400. The elastic sensing end refers to the elastic element in the weighing sensor used to sense pressure and convert gravity signals into electrical signals.

[0050] When the humidifier is placed on a platform or the ground, the elastomer sensing end first contacts the bearing surface and bears the main pressure. At this time, the load cell is in effective working condition and can accurately detect changes in the weight of the water tank. The support feet, due to their lower height, form a gap with the bearing surface after the elastomer sensing end is compressed, providing auxiliary support only when the equipment is subjected to additional impacts or overloads. Through the height difference between the elastomer sensing end and the support feet, the weight of the equipment and the water tank are transmitted to the load cell via the elastomer sensing end, while the support feet only bear the mechanical load under extreme conditions, preventing the elastomer from undergoing plastic deformation or failure due to long-term pressure.

[0051] This embodiment separates the weighing detection from the structural support function by utilizing the height difference between the support foot and the sensing end of the elastomer. This ensures the measurement accuracy of the sensor under normal operating conditions while preventing sensor overload damage through mechanical limiting. It achieves stable operation of the load cell in detachable water tank level monitoring, effectively solving the measurement error problem caused by the direct contact between the bottom surface of the equipment and the bearing surface. Simultaneously, it avoids the failure of the elastomer due to long-term pressure or impact, extending the sensor's service life.

[0052] like Figure 3As shown, in some embodiments, a cooling fan 440 is provided at the center of the base plate 400. The cooling fan accelerates the transfer of heat from the electromagnetic heating components and circuit board to the external environment through active airflow circulation, preventing heat from accumulating at the bottom of the housing and causing component aging or performance degradation.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the water tank 300 has an opening at its top, and the edge of the opening is bent outward to form a support edge 330. A support ring 150 protrudes upward from the open edge of the housing 100 at the top of the receiving tank 110, and the support edge 330 overlaps the support ring 150. The support edge refers to the annular flange structure formed by bending the edge of the opening outward, used to distribute the weight of the water tank and form a contact surface with the housing. The support ring refers to the annular boss formed by extending upward from the top edge of the housing, used to define the horizontal position of the water tank and provide axial support. The annular protrusion of the support ring and the annular flange of the support edge form a concentric fit, ensuring that the bottom of the water tank remains parallel to the microcrystalline panel and avoiding poor local contact due to tilting.

[0054] When the water tank is placed, the supporting edge overlaps the bearing surface of the supporting ring, and the annular contact area ensures even weight distribution. During disassembly, the lockless design between the supporting edge and the supporting ring allows the water tank to be lifted vertically without rotation or unlocking. This embodiment enables tool-free quick assembly and disassembly of the water tank from the shell. The surface contact between the supporting edge and the supporting ring effectively reduces local pressure and prevents liquid leakage caused by tank deformation.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments, the water tank 300 includes a connecting ring 340, the inner side of which is provided with a lower ring groove and an upper ring groove, the supporting edge 330 of the water tank 300 is embedded in the lower ring groove, and the outer edge of the cover plate 310 is embedded in the upper ring groove.

[0056] In this embodiment, the connecting ring is made of a flexible sealing material, such as rubber or silicone. During assembly, the connecting ring is fitted onto the support edge of the water tank, corresponding to the lower ring groove. Then, the outer edge of the cover plate is embedded into the upper ring groove. The connecting ring connects the cover plate to the water tank, preventing liquid from seeping out along the side wall of the water tank. When the water tank is installed onto the shell support ring, the lower part of the connecting ring acts as an intermediate load-bearing component, evenly transferring the weight of the water tank to the support ring, avoiding localized stress concentration that could lead to structural deformation, and simultaneously preventing steam from unexpectedly escaping from the edge of the cover plate.

[0057] like Figure 2 and Figure 3As shown, in some embodiments, the housing 100 has a top cover 160, the inner side of the top cover 160 is provided with a fastening member 161, and the outer side of the support ring 150 is provided with a fastening position 151. The top cover 160 presses the connecting ring 340, the support edge 330 of the water tank 300, and the outer edge of the cover plate 310 onto the support ring 150 through the cooperation of the fastening member 161 and the fastening position 151.

[0058] In this embodiment, when the top cover is on the housing, the latching element and the latching position are horizontally offset from each other. At this time, by rotating the top cover, the latching element moves circumferentially and engages with the latching position, completing the axial locking. The latching element and the latching position cause the vertical pressure generated by the top cover to press the connecting ring, support edge, and outer edge of the cover plate against the support ring, forming a continuous sealing interface to prevent steam leakage from the outer edge of the cover plate or the assembly gap between the cover plate and the water tank.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 100 is recessed on the outer side of the support ring 150 to form a groove 152, and the groove 152 is symmetrically arranged on both sides of the support ring 150. In this embodiment, the groove refers to the recessed area on the outer side of the support ring, which can be formed on the surface of the housing through stamping or injection molding processes to provide operating space. When installing or disassembling the water tank, the recessed area formed by the groove can accommodate fingers or tools, avoiding slippage caused by the excessive smoothness of the outer surface of the support ring during operation. This embodiment optimizes the operating space during the installation and disassembly of the water tank, reducing the risk of slippage due to improper force application.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the lower side of the cover plate 310 is provided with a plurality of protrusions 311. The protrusions can improve the structural strength of the cover plate, making it less prone to deformation or denting when subjected to steam pressure (such as thermal expansion and contraction during heating) for a long time, and the protrusions can condense water droplets during the steam rise process, which can guide the condensate backflow.

[0061] like Figure 2As shown, in some embodiments, the upper cover 160 has a through hole 162 corresponding to the steam port 320 of the cover plate 310. The steam port 320 is located at the center of the cover plate 310. The steam port 320 is provided with a steam bottom cover 321 and a steam top cover 322. The outer edge of the steam bottom cover 321 is embedded in the steam port 320. The steam top cover 322 is pressed onto the steam bottom cover 321 by the upper cover 160. The steam top cover 322 has a circular hole at its center. The steam bottom cover 321 has a plurality of arc-shaped holes arranged in a circular array around the circular hole. The arc-shaped holes are staggered from the circular holes. The staggered arrangement of the arc-shaped holes and the circular holes means that the arc-shaped holes and the circular holes do not overlap in the vertical direction, so that the steam flow path first enters from the arc-shaped holes, then converges towards the center between the steam bottom cover and the steam top cover, and finally sprays upward from the circular holes. This steam flow path allows liquid droplets in the steam to adhere to the wall they flow through and then flow back, while the dry steam is discharged upwards through the round holes. Simultaneously, the staggered arrangement of the arc-shaped and round holes prevents foreign objects from directly entering the channel and can intercept solid particles.

[0062] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
