This disclosure claims priority to the Chinese patent application with application number 202211101264.7 and titled "Atomizer" filed with the State Intellectual Property Office of China on September 9, 2022, the entire content of which is incorporated into this disclosure by reference.

Technical field

The present disclosure relates to the field of atomization technology, and in particular, to an atomizer.

Background technique

An atomizer is a device that breaks liquid molecule clusters into tiny liquid particles and disperses them in gas. The nebulizer is an important component of the atomization system, and its performance has a significant impact on the precision of the measurement and chemical interference. Therefore, the atomizer is required to have stable spray, fine and uniform droplets, and high atomization efficiency.

Atomizers have been widely used in a variety of industries. There are four main structures: ultrasonic atomizer, compressed air atomizer, mesh atomizer, and evaporator. atomizer.

Among them, the ultrasonic atomizer uses the principle of stirring and breaking the air bubbles generated by the vibration of the ultrasonic vibrator in the liquid to atomize the atomized liquid. The compressed air atomizer uses the compressed air generated by the air pump to form a Venturi negative pressure effect through the high-speed airflow at the mouth of the small tube. It absorbs the liquid in the liquid storage tank and sprays it onto the barrier together with the compressed air or other fluids. Under high-speed impact, the droplets splash around and break into mist particles, which are ejected from the mist outlet tube. The mesh atomizer uses the mechanical vibration of the mesh plate densely packed with tiny hole-shaped nozzles, and uses the one-way pumping function of the tiny hole-like nozzles on the mesh plate to squeeze the liquid from one side of the mesh plate to the other side. Achieve atomization. The evaporative atomizer uses a heater to directly heat the atomized liquid to weaken the binding force between liquid molecules, and combines it with blowing and suction by a fan to form atomization.

The above four atomizers on the market mainly have three structures for extracting atomized liquid, gravity difference method, negative pressure suction type, and cotton rope capillary suction type;

Among them, the gravity difference method, such as ultrasonic atomizer, mainly uses the liquid level difference between the liquid storage tank and the atomization chamber. The float valve controls the liquid level height in the atomization chamber. The gravity difference of the atomization liquid itself is used to control the liquid level from the liquid storage tank. Flows into the atomization chamber; for example, a method for extracting atomized liquid from a mesh atomizer is to set the atomization mesh at intervals between the liquid storage tank and the atomization chamber and at the lower bottom of the liquid storage tank. One side is filled with atomization liquid, and the other side of the atomization mesh is the atomization chamber, which uses the gravity difference of the atomization liquid to supply liquid; negative pressure suction type, such as compressed air atomizer, absorbs atomization through negative pressure liquid; cotton rope capillary suction type, such as a mesh atomizer, the atomization liquid extraction method is to use a cotton swab to extract the atomization liquid upward from the liquid storage tank to the atomization piece; such as evaporative electronic cigarette atomizer, with The cotton rope absorbs the atomized liquid, and the heating wire is wound around the cotton rope to evaporatively heat the atomized liquid to achieve evaporative atomization.

At present, the specific application of the above extraction methods of atomized liquid has led to the following outstanding problems in several related atomizers:

Among them, atomizers that extract atomized liquid based on the principle of gravity difference, such as ultrasonic type, mesh type atomizer liquid storage tank or When the atomization chamber body tilts, shakes, or the liquid level switch fails during use, the atomization vibrator may be short of liquid and burn out instantly due to poor heat dissipation. The normal service life of ultrasonic and mesh-type atomization vibrators is generally 1,000 years. Within the range of ~4000 hours;

Among them, atomizers that extract atomized liquid based on the negative pressure suction principle, such as compressed air atomizers, need to generate ≧KPa level air pressure, so piston pumps are generally used. During use, the piston frequently moves back and forth and causes friction, resulting in normal The service life is generally in the range of 1,000 to 4,000 hours, and it is relatively large and heavy;

Among them, the atomizer uses the atomization liquid extraction method based on the cotton rope stick capillary suction principle. For example, a mesh atomizer uses a cotton rope stick to extract the atomized liquid upward from the liquid storage tank to the atomization piece. The cotton stick is generally also It is relatively soft and prone to blockage. Once sufficient atomization liquid in the atomization piece cannot be effectively ensured and is not detected in time, the atomization vibrator may burn out instantly. Among them, the electronic cigarette atomizer uses a heating wire wrapped around a cotton rope filled with atomized liquid to evaporatively heat the atomized liquid. The atomized liquid cotton rope is particularly easy to be scorched. The atomized liquid cotton rope is used for single or multiple uses. It is designed with a service life of several hours to a hundred hours. The service life is short and the frequency of replacement is too high.

Summarizing the four mainstream atomizers with the above three liquid extraction methods currently on the market, they not only have shortcomings such as the main parts of the atomizer are easily damaged, the actual life is too short, frequent replacement and maintenance, the shell and even the circuit must be disassembled, and the cost of use and replacement is high; but also the weight It is not light, small in size, not simple in structure, and requires human supervision to ensure stable usage conditions.

In different industries, the requirements for the use characteristics of atomizers and atomizers are also different. For example, in the automotive aftermarket industry, in order to save energy, reduce emissions, and reduce people’s fuel expenses, vehicle-mounted atomizers are used to atomize combustion accelerants as atomized liquids and transport them to the combustion chamber of the engine through the engine air intake system. This allows the engine's fuel to be fully burned, improves the engine's power, saves energy, and reduces harmful emissions.

Some of this type of atomized liquid has the characteristics of being difficult to volatilize, and its kinematic viscosity has a great correlation with temperature. When the outdoor temperature is low, the atomized liquid is in a positional condensation state; in a lower temperature range, the atomized liquid The liquid will be in a frozen state, and the extraction, diffusion, and separation of the atomized liquid are very difficult. Since the four mainstream types of atomizers currently on the market generally do not have specific temperature controls, it is difficult to effectively atomize.

As an atomizer for vehicle use, it is best to comprehensively meet the requirements of unmanned detection, high reliability and stability in shaking situations, easy maintenance and disassembly, low cost, limited space requirements, light weight and small size, and no risk of parts scattering, and It is adaptable to a variety of temperatures, especially outdoor low-temperature environments, and the atomizer parts can be manually replaced as consumables. Based on the fatal shortcomings and obvious shortcomings of the four mainstream types of atomizers currently on the market, this requires the development of new atomizers and atomizers.

In this embodiment, , the diameter of the micro-holes 104 is 0.1mm, and the distance between the micro-holes 104 is 2mm. The liquid molecules of the atomized liquid diffuse to the diffusion separation part 102, combine with several micropores 104, and diffuse to form a liquid film of the atomized liquid.

As shown in Figures 4 and 5, in this embodiment, the above-mentioned atomizing part is installed in an atomizer. The atomizer includes an upper cover 3 and a tank 2 for storing atomized liquid. The cover 3 is packaged on the tank 2. The hot air jet body 1 is positioned and installed on the tank 2 and is located in the upper cover 3. The extraction part 101 extends into the tank, and the diffusion separation The portion 102 is located in the direction of the jet outlet of the hot air jet body. The hot air jet body 1 can separate the atomized liquid on the atomizing member into atomized particles.

Specifically, as shown in Figures 6 and 7, the hot air jet body 1 includes a housing 11, a heating core 12 and a power fan 13 installed in the housing 11;

The hot air jet body 1 also includes a jet outlet 14 extending from the casing 11 to the outside of the tank 2 and/or the upper cover 3, and the jet outlet 14 is connected to the inside of the casing 11; In the embodiment, the jet outlet 14 of the casing 11 is located in the middle of the connection between the tank 2 and the upper cover 3 and extends to the outside to facilitate access to the air intake system of the engine (not shown in the figure).

The heating core 12 includes a heating air duct 120 extending in the same direction as the jet outlet 14 . The heating air duct 120 runs through the middle of the heating core 12 . The power fan 13 corresponds to the heating air duct 120 , driving the air source to flow along the heating air duct 120 toward the jet outlet 14;

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 .

The power fan 13 generates an air source that enters the heating air duct 120 of the heating core 12, and then conducts heat transfer and heats the air flow through the heating core 12 to form hot air. With the continuous operation of the power fan 13, the hot air is discharged from the air outlet of the heating air duct 120, and The atomized liquid on the atomizing component 4 is sprayed and atomized through the densely distributed micro holes 104, and the atomized particles of the atomized liquid are ejected from the jet outlet 14 of the housing 11 and enter the air intake system of the engine.

In this embodiment, there are two power fans 13, and they are both located at the air inlet of the heating air duct 120. The two power fans 13 are connected in series through the air guide 17. 17 Reduce the pressure loss between the two power fans 13. The two power fans 13 are both brushless axial flow fans, ensuring that the power fans 13 can provide a stable air source in the heating air duct 120 of the heating core 12, and at the same time, can make the air source flow from the jet outlet of the housing 11 in the form of a jet. 14 discharge.

In another embodiment, there are two power fans 13, and they are respectively provided at the air inlet and outlet of the heating air duct 120. The power fan 13 located at the air inlet of the heating air duct 120 is a shaft. Flow fan, the power fan 13 located at the air outlet of the heating air duct 120 is a centrifugal fan. It blows air through the brushless axial flow fan at the air inlet of the heating air duct 120 and at the same time draws air with the centrifugal fan at the air outlet of the heating air duct 120. By cooperating with each other, an air source can be provided in the heating air duct 120 of the heating core 12 and discharged from the jet outlet 14 of the housing 11 in the form of a jet.

As shown in Figure 5, Figure 6 and Figure 7, in this embodiment, the housing 11 includes an upper housing 111 and a lower housing 112 that are fitted and installed with each other, and the heating core 12 is embedded therein. Both the housing 111 and the lower housing 112 are made of insulating materials.

In addition, as shown in FIG. 8 , the heat conduction section of the lower housing 112 is provided with a plurality of heat conduction fins 5 for preheating, and the plurality of heat conduction fins 5 are distributed on both sides of the lower housing 112 . side, and extends toward the side of the lower housing 112, and in the other direction, the thermal conductive fins 5 extend to the end of the lower housing 112;

The air outside the atomizer originates from the external air inlet 31 of the upper casing and enters the air source preheating space formed by the upper casing air inlet hood 11101 and the lower casing air inlet preheating fin 11201. The preheated air source then flows through the upper casing. The end 11102 of the air inlet hood of the housing enters the power fan 13;

The air outside the atomizer that enters from the external air inlet 31 of the upper housing is preheated through the air source preheating space of the upper housing air inlet hood 11101 and the lower housing air inlet preheating fin 11201. It realizes air source folding two-stage heating, and uses the heat energy emitted by the heating core 12 twice, which greatly improves the heat transfer efficiency; it also eliminates the possibility of directly entering the power fan when the temperature of the air source outside the atomizer body is too low. 13 and may cause the risk of difficulty in starting the power blower 13.

Since the upper housing 111 is installed on the lower housing 112 and the end of the upper housing 111 covers the end of the lower housing 112 , a plurality of the heat conduction fins 5 are located on the upper housing 111 On the inside, the air source preheating space formed by the upper case air inlet hood 11101 and the lower case air inlet preheating fins 11201 is formed. The heat conduction section rapidly heats up through the work of the heating core 12, so that the temperature of the multiple heat conduction fins 5 also increases. The power fan 13 is installed on the heat conduction section of the lower housing 112 and is located on the rear end side of the heating core 12. The shell 111 is closed on the lower shell 112, and the power fan 13 and the heat conduction fin 5 are closed at the same time. After the power fan 13 is working, the air outside the atomizer comes from the external air inlet 31 of the upper cover and is preheated. The air source then flows through the end 11102 of the upper casing air inlet hood and enters the power fan 13; the lower casing air inlet preheating fin 11201 and the upper casing air inlet hood 11101 and the upper casing air inlet hood end 11102 are all affected by the The heating of the heating core 12 through heat transfer can effectively preheat the air source, thereby improving the heating efficiency of the heating air duct 120 in the heating core 12 to the air source. Especially in low-temperature environments, it can play a very good role in heating the air source. Preheating effect.

As shown in FIG. 9 , in order to realize heating of the heating core 12 , an electric heating wire 15 wound along its extension direction is provided on the outer wall of the heating core 12 . The electric heating wire 15 is arranged adjacent to the heating air duct 120 , an installation slot 16 for installing the electric heating wire 15 is provided on the outer wall of the heating core 12. The electric heating wire 15 is installed in the installation slot 16, so that the distance between the electric heating wire 15 and the heating air duct 120 is closer. The electric heating wire 15 is connected to an external power supply. The electric heating wire 15 can heat the heating core 12. The wall thickness of the heating core 12 is relatively thin. The heating of the electric heating wire 15 can quickly transfer the heat to the heating air duct 120 inside the heating core 12. , so that the air source entering the heating air duct 120 can be quickly heated and the temperature of the air source can be increased.

In addition, since the heating core 12 has a length limit, the length of the heating air duct 120 inside the heating core 12 is limited. In order to realize that after the air source entering the heating air duct 120 is heated, the hot air discharged can atomize the atomized liquid. , the temperature of the wind source needs to meet certain requirements. In this embodiment, the heating air duct 120 includes a middle guide air duct 121 located in the center of the heating core 12 and a plurality of outer guide air ducts 122 arranged in the circumferential direction of the middle guide air duct 121. The guide air ducts and the outer guide air duct 122 both extend in the same direction;

The middle guide air duct 121 is connected with a plurality of the outer guide air ducts 122, which facilitates the air source to enter the heating air duct 120. Among the various guide air ducts, the intersection through the guide air ducts increases the heat transfer effect of the air source located in the heating air duct 120, and avoids the high temperature of the air source near the heating core 12 at the edge of the heating air duct 120, while the heating air duct 120 The temperature of the air source in the center is low.

In order to further improve the mutual integration effect of the air sources 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 plurality of outer guide air ducts 122 are provided with guide threads. The thread directions of the guide threads in 122 are all the same.

In actual use, the thread direction of the guide threads in the outer guide air duct 122 can be opposite to the thread direction of the guide threads in the middle guide air duct 121 .

The air source flows along the guide threads in each guide air duct.
