Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, and more particularly to an atomization structure with a replaceable heating wire. Background Technology

[0002] With the rapid development of atomization technology, atomizing devices are being accepted by more and more users. Besides being widely used in humidifiers and electronic cigarettes, atomization technology is also being introduced into stage equipment such as bubble machines to enhance stage effects.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1 to 3As shown, this utility model relates to an atomizing structure with a replaceable heating wire 21, including a housing assembly 10 and at least two sets of atomizing core assemblies 20. The housing assembly 10 defines a liquid storage space 101 and an atomizing channel 102. The atomizing core assembly 20 is at least partially disposed within the atomizing channel 102 and communicates with the liquid storage space 101. The atomizing core assembly 20 is used to receive liquid from the liquid storage space 101 and heats up when energized to atomize the received liquid. The at least two sets of atomizing core assemblies 20 heat up alternately.

[0024] Compared to existing technologies, traditional single heating wire 21 structures require continuous operation current, while this solution distributes the heat load across multiple heating elements through alternating operating modes. This design not only reduces the operating time of a single heating wire 21 but also promotes natural cooling of the elements during the intermittent periods, fundamentally improving the problem of thermal stress concentration.

[0025] Through the above technical solution, this application effectively extends the service life of a single heating element by at least two times, while maintaining a continuous and stable output of atomization effect. In equipment requiring long-term operation, such as stage fog machines, users do not need to frequently stop to replace the atomizing coil, significantly improving equipment efficiency. The redundant design of two sets of atomizing coils also allows basic functions to be maintained in the event of a single set failure, enhancing system reliability.

[0026] The housing assembly 10 is provided with at least two air outlets 103 communicating with the outside, and the atomizing channel 102 is provided with at least two atomizing ends 104. The atomizing end 104 refers to the section in the atomizing channel 102 that is directly connected to the air outlets 103. At least one atomizing core assembly 20 is provided at the connection between the atomizing end 104 and the air outlet 103.

[0027] When the two sets of atomizing core components 20 operate alternately, the air outlet 103 corresponding to each atomizing end 104 forms an independent airflow channel. Taking two atomizing ends 104 as an example, when the first atomizing core component 20 is working, the high-speed airflow generated by its atomizing end 104 is discharged through the corresponding air outlet 103, while the second atomizing core component 20 is in standby mode. When switching operating modes, the second atomizing core component 20 begins to heat up and atomize, and the airflow channel automatically switches to the second air outlet 103. This dual-channel structure makes the working area of ​​each atomizing core component 20 relatively independent, avoiding cross-interference.

[0028] By setting a corresponding number of atomizing ends 104 and air outlets 103, each atomizing core component 20 has its own dedicated airflow output path, effectively reducing airflow resistance. Simultaneously, the dual-channel design balances air pressure fluctuations and prevents backflow of the atomized liquid. The independently set atomizing ends 104 also reduce thermal interference between different heating components, maintaining the stability of the atomization effect.

[0029] In addition, multiple atomizing core components 20 can be added to each atomizing end 104, and the smooth switching of the working state of multiple atomizing core components 20 can extend the effective service life of a single heating wire 21.

[0030] The atomizing core assembly 20 includes a heating wire 21 and a liquid guide 22. The heating wire 21 is wound around the surface of the liquid guide 22 in a spiral or wavy shape.

[0031] The heating wire 21 is a metallic conductor that generates heat when energized, and can be made of nickel-chromium alloy or iron-chromium-aluminum alloy. The liquid conductor 22 is a porous medium with capillary adsorption properties, and can be made of porous ceramic or cotton fiber materials. The liquid conductor 22 continuously absorbs liquid from the liquid storage space 101 through capillary action, and the heat generated by the heating wire 21 when energized acts directly on the liquid-containing liquid conductor 22 through contact conduction.

[0032] The housing assembly 10 refers to the main body 13 structure that carries the atomization function. Specifically, it can be implemented by using a split injection molded housing with an internal partition structure to form a liquid storage and atomization area.

[0033] The housing assembly 10 includes a liquid storage chamber 11 and an atomizing chamber 12. The liquid storage chamber 11 has a liquid storage space 101 inside, and the atomizing chamber 12 and the atomizing core assembly 20 are disposed in the liquid storage space 101. An atomizing channel 102 is provided through the interior of the atomizing chamber 12, and the liquid storage chamber 11 has an air outlet 103 communicating with the atomizing channel 102. The atomizing core assembly 20 is disposed at the connection between the air outlet 103 and the atomizing channel 102. Specifically, the upper half of the annular liquid guide 22 is disposed at the atomizing end 104 of the atomizing channel 102, and the lower half is immersed in the liquid storage space 101; the heating wire 21 is wound around the upper half of the liquid guide 22 and is also disposed at the atomizing end 104 of the atomizing channel 102.

[0034] The liquid storage chamber 11 and the atomizing chamber 12 are separate structures. The liquid storage space 101 of the liquid storage chamber 11 is connected to the atomizing chamber 12 through a liquid guiding structure. The liquid is transported to the atomizing core assembly 20 through capillary action. When the atomizing core assembly 20 is powered on and heats up, the liquid is heated and atomized in the atomizing channel 102, and the generated aerosol is discharged from the air outlet 103 with the airflow. The atomizing core assembly 20 is located at the connection between the air outlet 103 and the atomizing channel 102, so that the atomization process is concentrated at the beginning of the airflow path, preventing incompletely atomized liquid from entering the atomizing channel 102.

[0035] The liquid storage chamber 11 is a container used to store the liquid to be atomized. Specifically, it can be implemented by adopting a hollow main body 13 structure, which forms a liquid storage space 101 to contain the liquid.

[0036] The liquid storage chamber 11 includes a hollow main body 13 and two faceplates 14 connected to both ends of the main body 13. The two faceplates 14 clamp and fix the atomizing chamber 12 inside the main body 13. The faceplates 14 are provided with air outlets 103 corresponding to the atomizing channel 102.

[0037] The hollow main body 13 refers to the core support structure that forms the liquid storage space 101. Specifically, it can be implemented by injection molding a hollow column, whose inner wall and the cover 14 cooperate to form a closed liquid storage area.

[0038] The faceplate 14 refers to the component at both ends of the liquid storage chamber 11 used to seal the main body 13 and connect it to the atomizing chamber 12. Specifically, it can be implemented using a plastic or metal structure with air vents 103. Its function is to provide a mounting and positioning base for the atomizing core assembly 20. The faceplate 14 refers to the sealing component covering both ends of the main body 13, which can be implemented using… The main body 13 and the faceplate 14 can be quickly assembled using a plastic part with a snap-fit ​​structure or a threaded connection. The clamping action fixes the position of the atomizing chamber 12 and forms a sealed interface to prevent displacement caused by vibration.

[0039] The atomizing chamber 12 refers to the component disposed within the liquid storage space 101 and extending through it to form the atomizing channel 102. Specifically, it can be implemented using a hollow tubular structure, whose function is to provide working space for the atomizing core assembly 20 and to communicate with the air outlet 103. The atomizing core assembly 20 is disposed between the faceplate 14 and the atomizing chamber 12.

[0040] The atomizing core assembly 20 also includes a pressure plate 23. The plate refers to the metal or plastic sheet-like structure in the atomizing core assembly 20 used for fixed connection. The pressure plate 23 is snapped into the faceplate 14 to fix the atomizing core assembly 20 to the faceplate 14.

[0041] Specifically, the pressure plate 23 can be implemented using a thin sheet structure with elastic clips. Its function is to enable quick installation and removal of the atomizing core assembly 20 through a snap-fit ​​engagement with the faceplate 14. The snap-fit ​​refers to the mechanical locking between the pressure plate 23 and the faceplate 14 through the engagement of protrusions and grooves. This can be achieved using a hook-type or elastic clamping structure, which simplifies the assembly process and improves structural stability through a threadless connection. Specifically, the atomizer coil assembly 20 is positioned within the clamping space between the faceplate 14 and the atomizing chamber 12, and the pressure plate 23 locks into place with a slot on the faceplate 14 through its own elastic deformation. When the pressure plate 23 is inserted into the faceplate 14, its snap-fit ​​structure generates a counterforce, pressing the atomizer coil assembly 20 firmly between the faceplate 14 and the atomizing chamber 12, thereby preventing displacement caused by vibration or airflow impact. This fixing method requires no additional fasteners, ensuring airtightness while allowing users to directly remove the pressure plate 23 to replace the atomizer coil assembly 20. A first sealing ring 17 is provided between the faceplate 14 and the main body 13, and a second sealing ring 18 is provided between the faceplate 14 and the atomizing chamber 12. The first sealing ring 17 is made of silicone or rubber material, and its function is to prevent liquid inside the liquid storage chamber 11 from leaking out from the joint between the faceplate 14 and the main body 13. The second sealing ring 18 is an annular seal provided between the faceplate 14 and the atomizing chamber 12. Specifically, it can be achieved by covering the outer wall of the atomizing chamber 12 with an elastic material. Its function is to isolate the liquid flow path between the atomizing chamber 12 and the liquid storage chamber 11, and prevent the aerosol generated during the atomization process from seeping back into the liquid storage space 101. Specifically, when the faceplate 14 is connected to the main body 13 by threads or snaps, the first sealing ring 17 is compressed between the contact surfaces of the two to form a radial seal, thereby sealing the liquid leakage path of the liquid storage chamber 11. During the assembly of the atomizing chamber 12 and the faceplate 14, the second sealing ring 18 is pressed between the outer wall of the atomizing chamber 12 and the inner hole of the faceplate 14 to form an axial sealing interface, preventing incompletely vaporized liquid in the atomizing chamber 12 from entering the liquid storage chamber 11 or the external environment through the gap. The housing assembly 10 also includes an upper housing cover 15 and a lower housing cover 16. The upper housing cover 15 and the lower housing cover 16 are connected to form a receiving cavity 106. The liquid storage tank 11 is installed in the receiving cavity 106. The upper housing cover 15 is provided with a liquid filling hole 105 communicating with the liquid storage tank 11. The liquid filling hole 105 is plugged with a plug 19.

[0042] The upper cover 15 and lower cover 16 of the outer casing can be made of injection-molded plastic parts. The upper cover 15 has a filling hole 105 on its surface to allow liquid to be added to the liquid storage tank 11. The lower cover 16 and the upper cover 15 can be fixed together by snap-fit ​​or threaded connection, forming a closed accommodating cavity 106 to protect the internal liquid storage tank 11. The filling hole 105 is a channel penetrating the upper cover 15, allowing liquid to be directly injected into the liquid storage tank 11 without disassembling the outer casing. The plug 19 is an elastic component used to seal the filling hole 105, specifically a conical plug made of silicone material, which achieves a seal through an interference fit to prevent liquid leakage.

[0043] When liquid needs to be added, the operator can directly pull out the silicone plug 19 inside the liquid filling hole 105 of the outer cover 15, and inject the liquid into the storage tank 11 using tools such as a syringe and funnel. After completion, the plug 19 is reinserted to maintain a seal.

[0044] In addition to alternating heating to extend its service life, the heating wire 21 of this application can also be replaced by disassembling and installing the entire housing assembly 10 from the atomizing device, further extending the service life of the atomizing device. This application also includes a contact conductive component 30 and a mounting base 40. The mounting base 40 is fixedly installed in the atomizing device, and the housing assembly 10 and the mounting base 40 are detachable. The atomizing core assembly 20 is electrically connected to the atomizing device through the contact conductive component 30.

[0045] The mounting base 40 refers to the mounting base used to support the housing assembly 10. Specifically, it can be an injection-molded plastic base with guide grooves on its surface for positioning the housing assembly 10. Detachable installation refers to an installation method that allows assembly without tools. This can be achieved using snap-fit ​​or threaded connections, facilitating quick replacement of the atomizing core assembly 20. To avoid affecting mist output, the mounting base 40 is provided with a through hole 401 corresponding to the air outlet 103 of the housing assembly 10, allowing mist to be output.

[0046] When the atomizer coil needs to be replaced, the housing assembly 10 can be detached from the mounting base 40. At this time, the contact conductive component 30 automatically disconnects from the circuit connection of the atomizing device. After the new atomizer coil assembly 20 is installed in the housing, the contact conductive component 30 re-forms a conductive circuit through the reassembly of the housing assembly 10 and the mounting base 40. During this process, the mounting base 40 is permanently fixed to the atomizing device body 13 as a mounting component, avoiding repeated disassembly that could cause wear to the structure of the device body 13.

[0047] The contact conductive component 30 refers to a contactable conductive part used to establish an electrical connection. Specifically, it can be implemented using an elastic metal spring structure, which automatically forms a conductive circuit during assembly. The contact conductive component 30 includes a first conductive spring 31 and a second conductive spring 32. The first conductive spring 31 is embedded in the housing assembly 10 and electrically connected to the atomizing core assembly 20. The second conductive spring 32 is embedded in the fixing base 40, with one end extending out of the fixing base 40 and electrically connected to the atomizing device, and its other end in contact with the first conductive spring 31 for conductivity.

[0048] When the housing assembly 10 is installed onto the mounting base 40, the contact ends of the first conductive spring 31 and the second conductive spring 32 form a conductive path through elastic pressure. The current of the atomizing device is transmitted to the first conductive spring 31 through the second conductive spring 32, thereby supplying power to the atomizing core assembly 20. When the housing assembly 10 is disassembled, the first conductive spring 31 and the second conductive spring 32 automatically separate, preventing damage to the circuit due to pulling. During the replacement of the atomizing core assembly 20, the circuit can be disconnected simply by separating the housing assembly 10 from the mounting base 40, without the need for additional operation of the conductive components.

[0049] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
