Description

Technical Field

[0001] This invention relates to the field of atomization technology, and more particularly to a hot air jet device for atomization. Background Technology

[0002] A nebulizer is a device that breaks down liquid molecular clusters into tiny liquid droplets and disperses them into a gas. As a crucial component of an atomization system, the nebulizer's performance significantly impacts the precision of measurements and reduces chemical interference. Therefore, nebulizers are required to provide stable spray, fine and uniform droplets, and high atomization efficiency.

[0003] Nebulizers are widely used in various industries, and there are four main types of their structures: ultrasonic nebulizers, mesh nebulizers, evaporative nebulizers, and compressed air nebulizers.

[0004] Among them, ultrasonic nebulizers utilize the principle of ultrasonic vibration to break up the test liquid and atomize it; mesh nebulizers use the principle of high-frequency mesh vibration and unidirectional pumping of mesh holes to break up the test liquid and atomize it; evaporative nebulizers use a heater to directly heat the atomizing liquid to weaken the binding force between liquid molecules, combined with a fan to blow and suck to form atomization; compressed air nebulizers use compressed air generated by an air pump to create a Venturi negative pressure effect through a high-speed airflow at a narrow tube opening, drawing liquid from the storage tank and spraying it onto an obstruction along with compressed air or other fluids, causing the droplets to break into mist particles under high-speed impact and spraying them out from the mist outlet pipe.

[0005] The conversion from liquid to mist phase is the core working process of an atomizer. Evaporative atomizers heat the atomized liquid to its boiling point to achieve evaporation, and the temperature must reach the boiling point of the atomized liquid. Ultrasonic atomizers and mesh atomizers both use an atomizing plate that is directly immersed in the liquid or one side of the atomizing plate. The vibrating atomizing plate generates heat while breaking up the liquid, but its temperature is not a controlled physical quantity. Compressed air atomizers use the Venturi jet principle for atomization and usually do not have a heater for the atomized liquid. Therefore, it is clear that none of the above four types of atomizers can meet the requirements of atomization at multiple temperatures, which is not limited to the boiling point.

[0006] Currently, all four types of atomizers have significant drawbacks: For example, ultrasonic and mesh atomizers may experience liquid shortages in the reservoir or atomization chamber due to tilting, shaking, or malfunctioning level switches, leading to instantaneous burnout due to poor heat dissipation. Furthermore, the normal lifespan of ultrasonic and mesh atomizer transducers is generally between 1000 and 4000 hours. Evaporative atomizers use a heating wire wrapped with a cotton rope soaked in atomizing liquid to evaporate and heat the liquid. If the liquid shortage causes the cotton rope to dry-burn or even ignite, the cotton rope is designed for single or multiple uses, with a lifespan of only a few hours to a hundred hours, resulting in a short lifespan and frequent replacements. Compressed air atomizers require a pressure of ≥KPa, so they typically use a piston pump. During use, the piston frequently reciprocates, causing friction, resulting in a normal lifespan of only 1000 to 4000 hours. They are also relatively large and heavy.

[0007] The requirements for the characteristics of atomizing fluids and atomizers vary across different industries. For example, in the automotive aftermarket, to save energy, reduce emissions, and lower fuel costs, vehicle-mounted atomizers are used to atomize combustion enhancers as a liquid. These atomized fluids are then delivered to the engine's combustion chamber through the intake system, ensuring complete combustion of fuel, increasing engine power, achieving energy savings, and reducing harmful emissions.

[0008] The use of vehicle-mounted atomizers has specific limitations, such as: unattended operation, bumpy conditions, mobile settings, compact spaces, wide temperature ranges, applicability to various atomizing liquids; complete and compact functionality, high heat transfer efficiency, simple structure, light weight and small size, low operating and maintenance costs, no risk of loose parts due to small screws, stable atomizing liquid properties, no damage to any components even when there is no liquid, significant safety and reliability, and ultra-long lifespan, etc. Based on the obvious shortcomings of the four mainstream types of atomizers currently on the market, atomizers with "extremely high universality requirements" under these specific limitations need to be developed entirely new.

[0013] The hot air jet body is also provided with an atomizing component for extracting atomized liquid, and part of the atomizing component is located on the air outlet of the heating air duct.

[0014] Furthermore, the outer wall of the heating core is provided with an electric heating wire wound along its extension direction, the electric heating wire is arranged adjacent to the heating air duct, and the electric heating wire is connected to an external power source.

[0019] Furthermore, at least two power fans are provided, and both are located at the air inlet of the heating air duct. Adjacent power fans are connected in series through a flow guide.

[0020] Alternatively, the heating air duct may have at least one of the aforementioned power fans at both its air inlet and air outlet.

[0021] Furthermore, the housing includes an upper housing and a lower housing that are fitted together, and the heating element is sealed between the upper housing and the lower housing;

[0022] The heating element is equipped with a temperature switch and a temperature sensor, and both the temperature switch and the temperature sensor are assembled in contact with the heating element.

[0023] Furthermore, the lower housing is provided with a plurality of fins for preheating the air intake. The plurality of fins are distributed on both sides of the lower housing and extend laterally toward the lower housing. In another direction, the fins extend to the end of the lower housing.

[0024] The upper housing is mounted on the lower housing, with the end of the upper housing covering the end of the lower housing, and the plurality of fins are located inside the upper housing.

[0032] This invention provides a hot air jet device for atomization, which, through a set of temperature control for the heating core, can achieve synchronous heating of multiple targets, such as air, atomizing liquid in the canister, and atomizing liquid on the atomizing component, by differential temperature. It is a highly integrated overall design. The through-flow of each guide air channel in the heating core, the threaded structure in the guide air channel, and the two-stage folding heating of air all significantly improve the heat transfer efficiency, comprehensively solving the problems of completing multi-target heating under the constraint of minimum space volume and requiring high heating rate with a short heating element.

[0033] The temperature control of the heating element, combined with the indirect hot air bath heating method of the power fan to the atomizing component, effectively prevents overheating of the atomizing component and the atomizing liquid, and also effectively avoids the risk of component burnout due to insufficient liquid.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a hot air jet device for atomization is installed inside an atomizer. The hot air jet device for atomization includes a hot air jet body 1. The atomizer includes a tank 2 and an upper cover 3. The upper cover 3 is encapsulated on the tank 2. The hot air jet body 1 is positioned and installed on the tank 2 and located inside the upper cover 3.

[0048] The hot air jet body 1 includes a housing 11, a heating element 12 and a power fan 13 installed inside the housing 11;

[0049] The hot air jet body 1 also includes a jet outlet 14 extending from the shell 11 to the outside of the tank 2 and the upper cover 3. The jet outlet 14 is in communication with the inside of the shell 11. In this embodiment, the jet outlet 14 of the shell 11 is located in the middle of the connection between the tank 2 and the upper cover 3 and extends to the outside, so as to facilitate the connection of the jet outlet 14 with the outside.

[0050] The heating element 12 includes a heating air duct 120 extending in the same direction as the jet outlet 14. The heating air duct 120 passes through the middle of the heating element 12. The external air source of the atomizer enters the air source preheating space formed by the upper shell air inlet 31 and the lower shell air inlet preheating fins 11201. The preheated air source then flows through the end 11102 of the upper shell air inlet 13 and enters the power fan 13. The power fan 13 corresponds to the heating air duct 120 and drives the air source to flow along the heating air duct 120 toward the jet outlet 14.

[0051] The hot air jet body 1 is also provided with an atomizing component 4 for extracting the atomized liquid in the tank 2, and part of the atomizing component 4 is located on the air outlet of the heating air duct 120.

[0052] The power fan 13 generates airflow that enters the heating duct 120 of the heating core 12, and then the airflow is heated again by direct heat transfer through the heating core 12 to form hot air. With the power fan 13 working continuously, the hot air is discharged from the air outlet of the heating duct 120 and heats and atomizes the atomizing liquid on the atomizing component 4, and sprays the atomized microparticles of the atomized liquid from the jet outlet 14 of the housing 11.

[0053] like Figure 5 As shown, to heat the heating core 12, an electric heating wire 15 is wound along its extension direction on the outer wall of the heating core 12. The electric heating wire 15 is arranged close to the heating air duct 120. An electric heating wire mounting groove 16 is provided on the outer wall of the heating core 12 for mounting the electric heating wire 15. The electric heating wire 15 is installed in the electric heating wire mounting groove 16, making the distance between the electric heating wire 15 and the heating air duct 120 closer. The electric heating wire 15 is connected to an external power source and can heat the heating core 12. The heating core 12 has a relatively thin wall thickness, and the heating of the electric heating wire 15 can quickly transfer heat to the heating air duct 120 inside the heating core 12, so that the air source entering the heating air duct 120 is quickly heated and the air source temperature is increased.

[0054] Furthermore, due to the length limitation of the heating core 12, the heating air duct 120 inside the heating core 12 has a limited length. The air source preheating space between the upper shell air inlet shroud 11101 and the lower shell air inlet preheating fins 11201 preheats the air entering from the external air inlet 31 of the upper shroud. This achieves two-stage heating with air source reversal, utilizing the heat energy emitted by the heating core 12 twice, greatly improving heat transfer efficiency. It also eliminates the risk that the power fan 13 might have difficulty starting if the external air source temperature is too low and directly enters the power fan 13.

[0055] Furthermore, in this embodiment, the heating air duct 120 includes a central guide air duct 121 located at the center of the heating core 12 and a plurality of outer guide air ducts 122 disposed in the circumferential direction of the central guide air duct 121, wherein the guide air ducts and the outer guide air ducts 122 extend in the same direction.

[0056] The central guide air duct 121 is connected to multiple external guide air ducts 122, which facilitates the entry of air sources into each guide air duct of the heating air duct 120. The air sources converge through the guide air ducts, which improves the efficiency of heat transfer and makes the air outlet temperature in each guide air duct of the heating air duct 120 more uniform.

[0057] In order to further improve the heat transfer efficiency and airflow temperature uniformity of the air source entering the heating air duct 120, guide threads are provided in the middle guide air duct 121 and the plurality of outer guide air ducts 122, and the thread direction of the guide threads in the plurality of outer guide air ducts 122 is the same.

[0058] The two-stage heating with reversible airflow and the flow of air along the guide threads in each guide duct, along with the convergence of these ducts, significantly increase the convergence and flow time of the air sources within the short hot air jet body 1. This greatly improves heat transfer efficiency, enabling the air source to rapidly heat up within the limited travel distance of the heating duct 120. This, in turn, allows for more efficient and stable atomization of the atomizing liquid, making it better suited for low-temperature environments.

[0059] In another embodiment, the thread directions of the guide thread inside the central guide duct 121 and the guide thread inside the peripheral outer guide duct 122 are reversed, so that the air source in the central guide duct 121 and the air source in the outer guide duct 122 form counterflow and interact, increasing the degree and time of convergence between the air sources, improving the heat transfer effect between the air sources, and enabling the air source to heat up quickly within the heating duct 120 with a limited stroke.

[0060] In this embodiment, two power fans 13 are provided, both located at the air inlet of the heating duct 120. The two power fans 13 are connected in series via a flow guide 17 to reduce pressure loss between them. Both power fans 13 are brushless axial flow fans, ensuring that they can provide a stable air source to the heating duct 120 of the heating core 12, while allowing the air source to be discharged in jet form from the jet outlet 14 of the housing 11.

[0061] In another embodiment, two power fans 13 are provided, and are respectively located at the air inlet and air outlet of the heating air duct 120. The power fan 13 located at the air inlet of the heating air duct 120 is an axial flow fan, and the power fan 13 located at the air outlet of the heating air duct 120 is a centrifugal fan. The brushless axial flow fan at the air inlet of the heating air duct 120 blows air, while the centrifugal fan at the air outlet of the heating air duct 120 draws air. The two work together to provide an air source for the heating air duct 120 of the heating core 12, and the air is discharged from the jet outlet 14 of the housing 11 in the form of a jet.

[0062] For example Figure 5 As shown, a temperature switch 8 and a temperature sensor 9 are also installed on the heating core 12. An electric heating wire 15 with an external power supply is provided on the outer wall of the heating core 12. The temperature switch 8 is electrically connected to the electric heating wire 15, and both the temperature switch 8 and the temperature sensor 9 are electrically connected to the circuit board. The temperature switch 8 and the temperature sensor 9 are both assembled in contact with the heating core 12. Through the contact between the temperature sensor 9 and the heating core 12, the temperature of the heating core 12 is detected and fed back to the circuit board. The heating core 12 can be stabilized at a preset temperature value through conventional control and adjustment by the circuit board. When the temperature of the heating core exceeds the preset upper limit temperature value, the heating circuit of the electric heating wire 15 is disconnected by the temperature switch 8, stopping the heating of the heating core 12 and preventing overheating and runaway accidents.

[0063] For example Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the housing 11 includes an upper housing 111 and a lower housing 112 that are installed together.

[0064] In addition, the heat-conducting section of the lower housing 112 is provided with a plurality of fins 5 for preheating. The plurality of fins 5 are distributed on both sides of the lower housing 112 and extend laterally toward the lower housing 112. In another direction, the lower housing air inlet preheating fins 11201 of the fins 5 extend to the end of the lower housing 112.

[0065] The upper housing 111 is mounted on the lower housing 112, and the end of the upper housing 111 covers the end of the lower housing 112. Multiple lower housing air inlet preheating fins 11201 are located inside the upper housing air inlet shroud 11101. The heat-conducting section heats up rapidly through the operation of the heating core 12, thereby raising the temperature of the multiple lower housing air inlet preheating fins 11201. The power fan 13 is installed on the heat-conducting section of the lower housing 112 and is located at the rear end of the heating core 12. The upper housing 111 covers the lower housing 112, simultaneously covering the power fan 13 and the upper housing air inlet cover 11201. After the power fan 13 is working, the external air source of the atomizer enters the air source preheating space formed by the upper housing air inlet cover 11101 and the lower housing air inlet preheating fins 11201 through the external air inlet 31 of the upper cover. The preheated air source then flows through the end 11102 of the upper housing air inlet cover and enters the power fan 13. The lower housing air inlet preheating fins 11201, the upper housing air inlet cover 11101, and the end 11102 of the upper housing air inlet cover are all heated by the heat transfer of the heating core 12, which can effectively preheat the air source.

[0066] Furthermore, in this embodiment, a flared opening 6 is provided on the housing 11 between the power fan 13 and the air inlet of the heating air duct 120, so that the air source provided by the power fan 13 can smoothly enter the heating air duct 120 under the guidance of the flared opening 6.

[0067] The heating element 12 is sealed and installed inside the housing 11. Both ends of the heating element 12 are sealed and connected to the inner wall of the housing 11 to prevent liquid on the hot air jet body 1 (such as atomizing liquid or other vapor-liquid mixtures seeping into the atomizing component 4) from entering the heating wire mounting groove 16 and the heating wire 15 on the heating element 12.

[0068] For example Figure 2 and Figure 7 As shown, in this embodiment, the tank 2 is provided with a plurality of support protrusions 21 for supporting the housing 11. Through the abutment between the housing 11 and the tank 2, when the heating core 12 is connected to electricity and heats up, the heat of the heating core 12 is transferred to the hot air jet body 1, and then to the tank 2 of the atomizer, which heats up the atomizing liquid in the tank 2, so that the atomizing liquid is in a liquid state, which facilitates the lifting and diffusion of the atomizing liquid.

[0069] Meanwhile, the supporting boss 21 of the tank body 2 has grooves and a frustum structure, which can prevent the liquid accumulated on the tank body 2 from contacting the shell 11.

[0070] Furthermore, when there is liquid on the upper surface of the tank 2, it can flow out from the overflow hole 24 of the tank and the overflow hole 32 of the upper cover, eliminating the risk of liquid intrusion into all the assembled components inside the hot air jet body 1 and ensuring the stable and reliable use of the atomizer.

[0071] In this embodiment, the tank 2 is provided with an injection port 22 for injecting atomizing liquid into it, an injection stopper 221, and an outlet 23 for the atomizing component 4 to extract the atomizing liquid; the injection stopper 221 is a breathable and overflow-proof type, which can effectively balance the air pressure inside the tank 2 without overflowing the liquid.

[0072] In this embodiment, the atomizer can be used in a vehicle. To prevent the atomized liquid in the canister 2 from overflowing and entering the hot air jet body 1 due to tilting or shaking, both the injection port 22 and the outlet port 23 are isolated from the hot air jet body 1. Preferably, the outlet port 23 is located outside the upper cover 3 and communicates with the inside of the canister 2, facilitating the atomizing component 4 to extract the atomized liquid from the canister 2 through the outlet port 23. The outer part of the insertion portion of the atomizing component 4 is a sealing sleeve (not shown in the figure), which seals against the outlet port 23 to prevent liquid from overflowing from the outlet port 23.

[0073] In this embodiment, the upper shell and lower shell 112 of the hot air jet body 1, and the tank 2 and upper cover 3 are all sealed with body pins. The power fan 13, guide vane 17, temperature switch 8, and temperature sensor 9 inside the hot air jet body 1 are all plug-in connected without screws, eliminating the risk of parts falling out. Furthermore, the injection stopper 221, being a plastic part, has an interference-fit thread connection with the injection port 22, resulting in extremely high friction. Moreover, the product is unlikely to loosen due to vibration, as it will only be disassembled and reassembled less than 30 times throughout its entire lifespan. The atomizing component 4 is connected to the liquid outlet 23 via a U-shaped sealing sleeve, and the insertion part is long enough that it cannot fall out unless forcibly pulled out manually. Therefore, this embodiment has no risk of parts falling out and is highly safe.

[0074] For example Figure 2 As shown, part of the atomizing component 4 extends into the tank 2 through the liquid outlet 23, and part of the atomizing component 4 is inserted into the slot 7 of the housing 11. The slot 7 is located at the air outlet of the heating air duct 120. The slot 7 penetrates the upper housing 111 and extends from the upper housing 111 to the lower housing 112. Part of the atomizing component 4 is embedded in the slot 7, so that the atomizing component 4 places the attached atomized liquid at the air outlet of the heating air duct 120, thereby realizing hot air bath heating and dense micropore jet atomization of the atomized liquid.

[0075] Specifically, the atomizing component 4 includes a sheet-like fabric body made of fiber fabric. The fabric body includes an extraction section extending into the tank 2 through the liquid outlet 23 and an atomization diffusion separation section located in the slot 7. The extraction section extends into the tank 2, and the liquid atomized liquid in the tank 2 is immersed in the extraction section. Through the adsorption and climbing properties of the fabric itself, the atomized liquid gradually climbs and extends to the atomization diffusion separation section, and is adsorbed on the atomization diffusion separation section to form an atomized liquid film. This facilitates the hot air generated in the heating air duct 120 to heat the atomized liquid on the atomization diffusion separation section in a hot air bath manner. This invention, combined with the densely porous atomizing sheet, constitutes a composite atomizer of hot air bath and densely porous jet. At the same time, the airflow generated by the power fan 13 passes through the dense micropores of the atomization diffusion separation section at high speed, forming a dense micro jet that atomizes and discharges the atomized liquid into the external engine intake system, so that the fuel in the engine combustion chamber can be fully burned, improving engine power, saving fuel consumption, and reducing harmful gas emissions.

[0076] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
