[0002] With the development of superheated steam technology, superheated steam has been widely used in many industries such as food processing, medical disinfection, garment manufacturing, and bathing and entertainment.

[0003] In related technologies, steam generators use water level monitoring components to monitor the water level inside the chamber and prevent dry burning. However, their function is limited and there is room for improvement. Summary of the Invention

[0005] The technical solution of this application is as follows: On the one hand, this application provides a water level monitoring component, including: The housing has an acoustic wave hole at its bottom; A partition is disposed within the housing to divide the housing into a first chamber and a second chamber, the first chamber being disposed above the second chamber, and the acoustic aperture being disposed at the bottom of the second chamber; Winding posts are spaced apart within the first cavity; An electromagnetic coil is disposed within the first cavity and wound around the circumference of the winding post; The magnetic oscillator is movably disposed within the second chamber.

[0006] The water level monitoring component provided in this application, when in use, generates low-frequency, low-energy sound waves through the acoustic aperture when the electromagnetic coil is powered by a low-frequency power supply. These low-frequency, low-energy sound waves are output through the acoustic aperture, and the reflected sound waves at the air-water interface monitor the real-time water level. When the electromagnetic coil is powered by a high-frequency power supply, it generates a high-frequency electromagnetic field with continuously switching cathode and anode. This electromagnetic field acts on the magnetic oscillator, causing it to move within the second chamber and generate high-frequency vibrations. This results in ultrasonic waves being generated in the water, which are then output through the acoustic aperture. The output ultrasonic waves clean scale from the cavity where the water level monitoring component is installed, demonstrating excellent practicality.

[0007] In some implementations, the magnetic oscillator is provided with a through hole that is opposite to and communicates with the acoustic hole to allow fluid to pass through.

[0012] On the other hand, this application also provides a steam generator, which includes a steam chamber and the aforementioned water level monitoring component, wherein the water level monitoring component is disposed on the steam chamber.

[0013] A steam generator equipped with the above-mentioned water level monitoring component can monitor the water level of the fluid in the steam chamber of the steam generator through the water level monitoring component, so as to replenish the fluid in the steam chamber in real time and avoid the dry burning phenomenon of the steam chamber.

[0014] In some embodiments, the steam generator further includes a steam heating element that passes through the steam chamber and is positioned below the water level monitoring assembly.

[0017] In some implementations, the superheated steam chamber is disposed on the steam chamber to miniaturize the superheated steam generator for easy carrying and installation. Attached Figure Description

[0023] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] This application is described below with reference to the accompanying drawings and specific embodiments: In related technologies, the temperature of the superheated steam output by the superheated steam generator does not exceed 200℃, and the size is relatively large, about 200mm*70mm*70mm, which makes it heavy and difficult to move and disassemble.

[0025] Based on the above-mentioned technical problems, this application provides a superheated steam generator to improve the temperature of superheated steam and reduce product size for easy handling and disassembly.

[0026] Figure 1 This is a schematic diagram of the structure of a superheated steam generator disclosed in an embodiment of this application. Figure 2 for Figure 1 Another structural diagram from the perspective of Figure 3 for Figure 1 A schematic diagram of the overheating heating element in the diagram, combined with... Figures 1-3 The superheated heating element 100 shown in this application embodiment is applied to a superheated steam generator. The superheated heating element 100 includes a superheated tube body 101 and a turbulence-disrupting element 102, wherein the turbulence-disrupting element 102 is fitted onto the circumferential surface of the superheated tube body 101.

[0027] The superheater 100 provided in this application has a flow-deflecting element 102 fitted onto the circumferential surface of the superheater tube 101. When the superheater 100 is applied in a superheated steam generator, the flow-deflecting element 102 increases the flow resistance of the steam entering the superheated steam generator from the steam inlet 201 along the length of the superheater 100, thereby reducing the pressure inside the superheated steam generator. This increases the steam flow velocity, thereby increasing the heat exchange efficiency between the steam and the superheater tube 101, raising the steam heating temperature, generating higher-temperature superheated steam, and improving the temperature of the superheated steam.

[0028] Combination Figure 3 The turbulence element 102 is a thin sheet that can transfer heat. When steam flows along the length of the superheated heating element 100, it can not only increase the flow speed of the steam, but also increase the heat exchange area between the superheated heating element 100 and the steam, so as to further increase the heating temperature of the steam.

[0029] Combination Figure 3 The turbulence-disrupting element 102 can be spirally mounted on the circumferential surface of the superheated tube body 101, so that the steam forms a spiral steam flow channel when it travels along the length of the superheated tube body 101, thereby further increasing the flow resistance of the steam and achieving a better heating effect.

[0030] Combination Figure 3 A slot can be provided on the circumferential surface of the superheated tube body 101, and the baffle 102 is inserted into the slot on the circumferential surface of the superheated tube body 101. In actual implementation, the baffle 102 can be initially positioned in the slot on the circumferential surface of the superheated tube body 101, and then the baffle 102 can be fixed in the slot on the circumferential surface of the superheated tube body 101 by welding, thus completing the assembly of the baffle 102 on the superheated tube body 101.

[0031] In this embodiment, the pitch of the turbulence-disrupting element 102 can be increased sequentially along the steam flow direction, thereby increasing the flow channels of adjacent turbulence-disrupting elements 102 sequentially, thus forming a turbulence-disrupting element gradually expanding nozzle effect to increase the steam flow rate and promote heat exchange between the heating pipe and the steam.

[0032] In other implementations, the flow channel can be varied with different pitch values ​​depending on the steam flow rate, enabling modes such as increasing and then decreasing, decreasing and then increasing, continuously increasing, and continuously decreasing the flow channel to adapt to various steam generators.

[0033] Of course, in other embodiments, the baffle 102 can also be directly welded to the circumferential surface of the superheated tube 101. Multiple baffles 102 can also be provided, each baffle 102 being annular, and multiple baffles 102 can be vertically connected to the circumferential surface of the superheated tube 101, thus forming... Figure 4 The superheated heating element 100 shown.

[0034] Based on the aforementioned superheated heating element 100, this application embodiment also provides a superheated steam generator. In conjunction with... Figure 1 as well as Figure 2 The superheated steam generator includes a superheated steam chamber 300 and the superheated heating element 100. Figure 5 for Figure 1 A schematic diagram of the internal structure of the superheated steam chamber, combined with... Figure 1 , Figure 2 as well as Figure 5 The superheated steam chamber 300 is provided with a steam inlet 201 and a superheated steam outlet 302. The superheated pipe body 101 of the superheated heating element 100 passes through the superheated steam chamber 300, and the turbulence 102 is provided inside the superheated steam chamber 300.

[0035] The superheated steam generator equipped with the superheated heating element 100 can input steam into the superheated steam chamber 300 through the steam inlet 201. After the input steam is heated by the superheated heating element 100, it generates high-temperature steam that meets the temperature requirements and is output from the superheated steam outlet 302 of the superheated steam chamber 300 for use.

[0036] The superheated steam generator equipped with the superheated heating element 100 described above can generate superheated steam at a higher temperature, thereby improving the temperature of the superheated steam and having great practicality.

[0037] The superheated steam generator shown in this embodiment allows for power control of the superheated heating element 100, thus enabling the superheated steam temperature to reach 100°C. It is adjustable within 300℃ to achieve different steam functions, such as high-temperature steaming, rapid steaming, and high-temperature steam washing, etc., to meet different power requirements.

[0038] Combination Figure 1 , Figure 2 as well as Figure 5In this embodiment of the application, the two ends of the superheated tube 101 of the superheated heating element 100 need to extend out of the superheated steam cavity 300 for connection with the wire to provide the electrical energy required for heating.

[0039] Combination Figure 1 , Figure 2 as well as Figure 5 The superheated steam cavity 300 of this application embodiment includes a plurality of parallel superheated cavities 203. The ends of two adjacent superheated cavities 203 are connected by a connecting cavity 204 so that the superheated steam cavity 300 is serpentine. Each superheated cavity 203 is provided with one or more superheated heating elements 100. The two ends of the superheated steam cavity 300 are respectively provided with a steam inlet 201 and a superheated steam outlet 302. This can increase the travel path of steam to generate superheated steam, thereby further increasing the temperature of the superheated steam and improving the temperature of the superheated steam.

[0040] In the embodiments of this application, the superheated steam cavity 300 includes two parallel superheated cavities 203 with a gap between them. One end of the two superheated cavities 203 is connected by a connecting cavity 204, making the superheated steam cavity 300 U-shaped. Each superheated cavity 203 is provided with a superheating element 100. The steam inlet 201 can be provided on the side of one superheated cavity 203, and the superheated steam outlet 302 can be provided on the side of the other superheated cavity 203.

[0041] Combination Figure 1 as well as Figure 2 The superheated steam generator of this application embodiment further includes a steam chamber 300, a steam heating element 400, and a connecting pipe 500. The steam chamber 300 is provided with an inlet 301 and a steam outlet 302. The steam heating element 400 passes through the steam chamber 300. The two ends of the connecting pipe 500 are respectively connected to the steam outlet 302 of the steam chamber 300 and the steam inlet 201 of the superheated steam chamber 300. The steam chamber 300 and the steam heating element 400 can form a steam generator. A fluid to be heated can be input through the inlet 301 of the steam chamber 300. After heat exchange by the steam heating element 400 within the steam chamber 300, the fluid is heated to generate steam. The generated steam is discharged through the steam outlet 302 of the steam chamber 300 to the connecting pipe 500, and then transported through the connecting pipe 500 to the superheated steam chamber 300 to generate superheated steam at a suitable temperature.

[0042] In this embodiment, the superheated steam cavity 300 can be integrally formed on the steam cavity 300 to reduce the overall size of the product and improve its portability and ease of installation.

[0043] Of course, in other embodiments, the superheated steam chamber 300 can also be set separately from the steam chamber 300, and the two are connected by a connecting pipe 500 to achieve steam transport.

[0044] Figure 6 for Figure 1 A schematic diagram of the interior of the steam chamber. Figure 7 for Figure 1 Top view, Figure 8 for Figure 7 A schematic diagram of the AA cross section, combined with Figures 6-8 In this embodiment of the application, a steam-water separation plate 303 may be provided inside the steam chamber 300. The steam-water separation plate 303 may be arranged horizontally to divide the steam chamber 300 into a lower steam generation chamber 304 and an upper steam-water separation chamber 305. A water inlet 301 is provided on the steam generation chamber 304, and a steam heating element 400 is provided inside the steam generation chamber 304. Fluid can enter the steam generation chamber 304 through the water inlet 301 and be heated into steam by the steam heating element 400. A steam vent 306 is provided on the steam separation plate 303 to connect the steam generation chamber 304 and the steam-water separation chamber 305. A steam outlet 302 is provided on the steam-water separation chamber 305. The generated steam can enter the steam-water separation chamber 305 through the steam vent 306 and be discharged through the steam outlet 302.

[0045] In this embodiment, the steam-water separation plate 303 can have multiple steam vents 306, or the steam-water separation plate 303 itself can be a grid plate. The steam heating element 400 is located below the steam-water separation plate 303. The fluid input from the water inlet 301 into the steam chamber 300 is heated by the steam heating element 400, and the generated steam rises. After being blocked by the steam-water separation plate 303, the steam and water are separated. The separated steam escapes from the steam vents 306 of the steam-water separation plate 303 and is discharged from the steam outlet 302. The separated fluid and impurities in the fluid will automatically flow back to the steam chamber 300, thereby reducing the condensate mixed in the steam and improving the saturation of the generated steam. Correspondingly, it can also generate superheated steam at a higher temperature, which has good practicality.

[0046] Furthermore, combined Figure 1 as well as Figure 2In this embodiment, the steam-water separation chamber 305 is disposed on one side of the top of the steam generation chamber 304, and the superheated steam chamber 300 is disposed on the other side of the top of the steam generation chamber 304. The steam outlet 302 and the steam inlet 201 are located at the same height to facilitate steam delivery. Additionally, one end of the connecting pipe 500 that connects to the steam inlet 201 can be disposed between the two superheated chambers 203 and bent towards the side of the superheated chamber 203 where the steam inlet 201 is located, thereby achieving communication between the connecting pipe 500 and the superheated steam chamber 300.

[0047] In this embodiment, the superheated steam cavity 300 can be integrally formed on the steam cavity 300 to reduce the overall size of the product, improve the product's portability, and facilitate installation.

[0048] In related technologies, the pressure inside the superheated steam chamber 300 and the pressure of the steam delivered to the superheated steam chamber 300 are roughly the same. In order to make the steam inside the superheated steam chamber 300 flow towards the superheated steam outlet, the size of the superheated steam chamber 300 must be increased, resulting in a large size of the superheated steam chamber 300, which is difficult to handle and disassemble. However, in the embodiments of this application, by providing a flow-deflecting element 102 on the superheated heating element 100, the pressure inside the superheated steam chamber 300 can be reduced, so as to realize the rapid flow and heat exchange of steam in the superheated steam chamber 300. This allows the size of the superheated steam chamber 300 to be miniaturized. In addition, the technical solution of integrally molding the superheated steam chamber 300 onto the steam chamber 300 can reduce the overall volume of the product. In actual production, the size of the superheated steam generator of the embodiments of this application can be 180mm*70mm*22mm, and the total weight is less than 600g, so as to achieve product miniaturization and improve product portability and ease of installation.

[0049] Furthermore, combined Figure 1 as well as Figure 2 In this embodiment of the application, the water inlet 301 is disposed at the end of the steam chamber 300, and the steam outlet 302 is disposed above the water inlet 301. A water level monitoring component 600 may be disposed inside the steam chamber 300. The water level monitoring component 600 can obtain the water level height inside the steam chamber 300 in real time, so as to replenish the fluid inside the steam chamber 300 in real time, so as to continuously obtain the required superheated steam, thereby forming a continuous and stable water supply system and ensuring a continuous steam flow.

[0050] Specifically, while steam is being generated, if the water level monitoring component 600 confirms that the fluid exceeds the set maximum height, the fluid delivery will be stopped. If the water level monitoring component 600 confirms that the fluid is at the set minimum height, the fluid will be controlled to be delivered into the steam chamber 300 so that steam can be continuously generated to form a continuous and stable water supply system, ensuring a continuous steam flow and preventing the steam chamber 300 from drying out.

[0051] Figure 9 for Figure 1 A schematic diagram of the water level monitoring component in the diagram. Figure 10 for Figure 9 A cross-sectional schematic diagram, combined with Figure 8 , Figure 9 as well as Figure 10 The water level monitoring component 600 of this application embodiment may include a housing 601, a partition 603, and a winding post 602. The housing 601 is disposed inside the steam chamber 300. The bottom of the housing 601 is provided with an acoustic wave hole 608. The partition 603 may be disposed horizontally inside the housing 601 to divide the housing 601 into a first chamber 606 and a second chamber 607. The first chamber 606 is disposed above the second chamber 607. The winding post 602 is disposed inside the first chamber 606. The electromagnetic coil 604 is disposed inside the first chamber 606 and wound around the circumference of the winding post 602. The magnetic oscillator 605 is movably disposed inside the second chamber 607.

[0052] In practical use, when the electromagnetic coil 604 is powered by a low-frequency power source, the electromagnetic coil 604 and the magnetic oscillator 605 generate low-frequency, low-energy sound waves. These low-frequency, low-energy sound waves can be output through the acoustic aperture 608. The reflected sound waves at the air-water interface monitor the real-time water level of the fluid, allowing for real-time replenishment of the fluid in the steam chamber 300 to prevent dry burning and ensure continuous acquisition of the required superheated steam. When the electromagnetic coil 604 is powered by a high-frequency power source, it generates a high-frequency electromagnetic field with continuously switching cathode and anode. This electromagnetic field acts on the magnetic oscillator 605, causing it to move within the second chamber 607 and generate high-frequency vibrations. This results in the magnetic oscillator 605 generating ultrasonic waves in the water, which are also output through the acoustic aperture 608. The output ultrasonic waves can clean scale in the chamber where the water level monitoring component is installed, demonstrating excellent practicality.

[0053] The superheated steam generator shown in this embodiment allows for the input of a low-frequency linear power supply at set intervals (e.g., 20ms), emitting a sound wave at these intervals. Initially, when the bottom of the housing is in contact with the fluid inside the steam chamber 300, the surface is wet. Once the housing separates from the fluid surface, the water pump automatically starts to supply fluid back to the initial state. Compared to conventional probe-type water level monitors, ultrasonic water level monitors avoid the phenomenon of scale buildup at the output section affecting monitoring performance.

[0054] In this embodiment of the application, the input of the high-frequency power supply can be controlled by the user, who can periodically turn on the control switch of the corresponding high-frequency power supply to periodically clean the scale in the corresponding cavity.

[0055] Combination Figure 10 In this embodiment of the application, the magnetic oscillator 605 may be provided with a through hole 609 that is opposite to and communicates with the acoustic hole 608, so that the ultrasonic waves generated by the winding column can be output through the through hole 609 and the acoustic hole 608 to confirm the water level.

[0056] In this embodiment, the winding post 602 can be fixedly disposed on the top of the partition 603. The two can be integrally formed or welded together, and no limitation is made here.

[0057] Combination Figure 8 , Figure 9 as well as Figure 10 The water level monitoring component 600 of this application embodiment also includes a sleeve 610, which is disposed in the first chamber 606. The electromagnetic coil 604 and the electromagnetic coil 602 are both disposed in the sleeve 610. The partition 603 is fixedly disposed at the bottom of the sleeve 610, that is, the partition 603 and the sleeve 610 are fixedly connected. When the housing 601 is assembled on the steam chamber 300, the magnetic vibrator 605 can be assembled in the housing 601 first, and then the sleeve 610 with the electromagnetic coil 604 and the winding post 602 can be fixed in the housing 601, which is convenient and quick.

[0058] Furthermore, combined Figure 8 In this embodiment of the application, the top of the housing 601 passes through the top of the steam chamber 300. The top of the housing 601 is open, and the sleeve 610 can be inserted into the housing 601 through the top of the housing 601 to realize the assembly of the sleeve 610 in the housing 601.

[0059] Specifically, the sleeve 610 can be assembled into the housing 601 by means of threaded connection or welding, and there is no restriction on this.

[0060] Combination Figure 8In this embodiment, the top of the steam chamber 300 may be provided with a connecting cylinder 611, and the top of the housing 601 is fixedly connected to the connecting cylinder 611, so that the entire water level monitoring component 600 can be assembled on the steam chamber 300. Specifically, the top of the housing 601 may be fixedly connected to the connecting cylinder 611 by means of threaded connection or welding, which is not limited here.

[0061] It should be noted that the water level monitoring component in this application embodiment can also be assembled in other cavities, and there are no restrictions on this.

[0062] Figure 11 for Figure 1 A schematic diagram of the steam heating element in the diagram, combined with... Figure 1 , Figure 2 as well as Figure 11 In this embodiment, the steam heating element 400 is disposed below the water level monitoring component. It includes an electric heating tube 401 and a water-proof sleeve 402, wherein the water-proof sleeve 402 is fitted onto the circumferential surface of the electric heating tube 401. Since the steam heating element 400 is disposed within the superheated cavity 203, it is in direct contact with the fluid, thereby avoiding the technical problem of low heat exchange efficiency caused by heat transfer through the shell 601 in related technologies. At the same time, the water-proof sleeve 402 fitted onto the circumferential surface of the electric heating tube 401 can also reduce the heat released by the electric heating tube 401 to the external environment, achieving energy saving while ensuring heat exchange efficiency. In addition, the water-proof sleeve 402 prevents the risk of water leakage from the electric heating tube 401, improves its resistance to water corrosion, and increases the service life of the steam heating element 400.

[0063] In this embodiment, the electric heating tube 401 is the heating element of the steam heating element 400. Its two ends are connected to electrical wires to provide the electrical energy required for heating. A water-proof sleeve 402 is fitted onto the circumferential surface of the electric heating tube 401. Since the steam heating element 400 is located within the superheated cavity 203, it directly contacts the fluid, thus avoiding the technical problem of low heat exchange efficiency caused by heat transfer through the shell 601 in related technologies. Simultaneously, the water-proof sleeve 402 fitted onto the circumferential surface of the electric heating tube 401 reduces the heat released by the electric heating tube 401 to the external environment, achieving energy saving while ensuring heat exchange efficiency. Furthermore, the water-proof sleeve 402 prevents the risk of water leakage from the electric heating tube 401, improving its resistance to water corrosion and increasing the service life of the steam heating element 400.

[0064] Combination Figure 11In this embodiment, the waterproof sleeve 402 may include an inner sleeve 4021 and an outer sleeve 4022. The inner sleeve 4021 is fitted onto the circumferential surface of the electric heating tube 401, with a distance between the two ends of the inner sleeve 4021 and the two ends of the electric heating tube 401, so that the two ends of the electric heating tube 401 protrude from the waterproof sleeve 402 to facilitate the connection between the electric heating tube 401 and the wire. The outer sleeve 4022 is fitted onto the circumferential surface of the inner sleeve 4021, with a distance between the two ends of the outer sleeve 4022 and the two ends of the inner sleeve 4021. Figure 11 The distance shown is not limited here. Of course, the two ends of the outer sleeve 4022 can also be flush with the two ends of the inner sleeve 4021.

[0065] In this embodiment, the inner sleeve 4021 can be made of a low-melting-point thermally conductive metal, such as gallium-aluminum alloy, gallium-bismuth alloy, gallium-tin alloy, gallium-indium alloy, etc., so that the electric heating tube 401 can be assembled in the inner sleeve 4021 by welding. The outer conduit can be made of stainless steel, such as 304 stainless steel, so that the outer sleeve 4022 can be assembled in the steam cavity 300 by welding, so that the steam heating element 400 has sufficient bearing pressure.

[0066] In actual implementation, the outer sleeve 4022 of the water-proof sleeve 402 can be welded to the overheated cavity 203 first, and then the inner sleeve 4021 with the electric heating tube 401 welded on it can be welded into the outer sleeve 4022. This method can avoid the deformation problem caused by the electric heating tube 401 being directly welded to the overheated cavity 203, thereby improving the assembly quality and use quality of the electric heating tube 401.

[0067] Of course, the superheater 100 can also be assembled onto the superheated steam cavity 300 by welding. In other embodiments, the steam heater 400 and the superheater 100 can also be assembled onto the corresponding cavity by bolts, which is not limited here.
