The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] Combine the following Figures 1 to 9 , describing an embodiment of the utility model.

[0043] Please refer to Figure 1 to Figure 3 As shown, the atomization assembly of the present application includes an atomization chamber 1, a compression assembly 2 and a nozzle assembly 3. A first accommodating chamber 11 is provided in the atomization chamber 1, and a liquid inlet portion 12 is provided in the atomization chamber 1. At least part of the compression assembly 2 is located in the first accommodating chamber 11. The compression assembly 2 can move relative to the atomization chamber 1 to generate a high-speed airflow. A guide channel (not shown in the figure) for the high-speed airflow to circulate is provided in the compression assembly 2. The nozzle assembly 3 is fixed on the compression assembly 2, and the nozzle assembly 3 is fluidically connected to the guide channel.

[0044] Specifically, under the action of the first external force, the compression component 2 in the first accommodating chamber 11 moves toward the liquid inlet portion 12 and compresses the gas between the liquid inlet portion 12 and the compression component 2. When the first external force is removed, the compression component 2 moves in the opposite direction under the action of the second external force, and the compressed gas flows back and generates a high-speed airflow, which enters the first accommodating chamber 11 through the liquid inlet portion 12 and mixes with the high-speed airflow. Under the action of the high-speed airflow, the atomized liquid is impacted into fine droplets and flows through the guide channel to the nozzle assembly 3 for spraying, thereby realizing low-temperature atomization. The atomized liquid does not need to be in direct contact with the high-temperature heating element, thereby avoiding the problems of burning, bitterness, and stickiness of the atomized liquid, thereby improving the user experience.

[0045] In this embodiment, the shape of the atomization bin 1 is not limited, and the atomization bin 1 can be box-shaped, cylindrical or other shapes. Preferably, the atomization bin 1 is a hollow cylindrical structure; the position of the liquid inlet 12 is not limited, and the liquid inlet 12 can be set at the bottom or side of the atomization bin 1. Preferably, the liquid inlet 12 is set at the bottom of the atomization bin 1; the first external force and the second external force are forces with opposite directions of action, and the types and power sources of the first external force and the second external force are not limited. The first external force and the second external force can be generated by a motor, a magnet, a cylinder, manpower or other devices. Preferably, the first external force is the pressing force applied to the compression component 2 by manpower, and the second external force is the elastic force of the elastic member. The atomization component does not need to be provided with parts such as a motor, a magnet, a cylinder, etc., which can simplify the parts layout of the atomization component and save production costs.

[0046] In this embodiment, the positional relationship among the nozzle assembly 3, the compression assembly 2 and the liquid inlet 12 is not limited. The nozzle assembly 3, the compression assembly 2 and the liquid inlet 12 can be arranged side by side left and right or spaced apart up and down. Preferably, the nozzle assembly 3, the compression assembly 2 and the liquid inlet 12 are spaced apart from top to bottom. The compression assembly 2 moves downward under the action of the pressing force and compresses the gas in the first accommodating chamber 11. After the pressing force is removed, the compression assembly 2 moves upward under the action of the elastic force of the elastic member. When the compressed gas flows back, an upward high-speed airflow is generated. The high-speed airflow atomizes the atomized liquid and drives the droplets to move upward to the nozzle assembly 3 for spraying.

[0047] In one embodiment, Figure 5 and Figure 6 As shown, the compression component 2 is in close contact with the cavity wall of the first accommodating chamber 11. Under the action of the first external force, the compression component 2 moves toward the direction close to the liquid inlet portion 12 and compresses the gas in the first accommodating chamber 11. Specifically, the compression component 2 includes a first valve body 21 and a second valve body 22. The outer wall of the first valve body 21 is in close contact with the cavity wall of the first accommodating chamber 11. The first valve body 21 has a first hollow channel 211, and the second valve body 22 has a second hollow channel 221. One end of the second valve body 22 close to the liquid inlet portion 12 extends into the first hollow channel 211 and is in close contact with the inner wall of the first hollow channel 211, so that the first hollow channel 211 is connected to the second hollow channel 221 to form a part of the guide channel, and the first valve body 21 and the second valve body 22 are linked in the movement direction of the compression component 2.

[0048] In this embodiment, the shape of the first valve body 21 is adapted to the shape of the atomization chamber 1. The first valve body 21 has a first surrounding wall 212 and a second surrounding wall 213. The first surrounding wall 212 is arranged to form a first hollow channel 211. The second surrounding wall 213 is arranged on the outside of the first surrounding wall 212. The first surrounding wall 212 and the second surrounding wall 213 are arranged at intervals. The outer wall of the second surrounding wall 213 is in close contact with the cavity wall of the first accommodating cavity 11, which can prevent the gas from overflowing from the outer wall of the second surrounding wall 213 and the cavity wall of the first accommodating cavity 11 when the compression component 2 compresses the gas, thereby affecting the effect of compressing the gas.

[0049] In some embodiments not shown, the first valve body 21 has a first surrounding wall 212 , which surrounds and forms the first hollow channel 211 , and an outer side wall of the first surrounding wall 212 is directly in contact with the cavity wall of the first accommodating cavity 11 .

[0050] In this embodiment, the shape of the second valve body 22 is adapted to the shape of the first hollow channel 211, and one end of the second valve body 22 close to the liquid inlet portion 12 extends into the first hollow channel 211 and is in close contact with the inner wall of the first hollow channel 211, thereby preventing high-speed airflow from overflowing from the gap between the outer wall of the second valve body 22 and the inner wall of the first hollow channel 211; the second valve body 22 can move relative to the first valve body 21, and an abutment portion 224 is provided on the second valve body 22, and the abutment portion 224 is arranged above the first surrounding wall 212. When the second valve body 22 moves downward, the abutment portion 224 contacts the upper end of the first surrounding wall 212 and drives the first valve body 21 to move.

[0051] In one embodiment, Figure 3 , Figure 5 and Figure 6 As shown, the compression assembly 2 also includes a fixing member 23, which has a sealing portion 231 and an inserting portion 233 that are interconnected. When the first valve body 21 moves toward the direction close to the liquid inlet portion 12, the end of the first valve body 21 away from the second valve body 22 is in sealing contact with the sealing portion 231, and the first valve body 21 drives the sealing portion 231 to move. The inserting portion 233 passes through the first hollow channel 211 and then extends into the second hollow channel 221. A first ventilation gap 235 is formed between the outer wall of the inserting portion 233 and the inner wall of the second hollow channel 221. The first ventilation gap 235 is fluidically connected to the first hollow channel 211 and the second hollow channel 221.

[0052] In this example, the sealing portion 231 is arranged below the first surrounding wall 212, and a sealing groove 232 with an opening facing upward is provided on the sealing portion 231. When the first valve body 21 moves downward, the lower end of the first surrounding wall 212 extends into the sealing groove 232 and is in sealing contact with the bottom wall of the sealing groove 232. The sealing portion 231 seals the lower end opening of the first hollow channel 211 to prevent gas from overflowing from the first hollow channel 211 during the compression process, thereby affecting the effect of compressing the gas; the inserting portion 233 is fixedly connected to the sealing portion 231, and the inserting portion 233 is located above the sealing portion 231. The inserting portion 233 passes through the first hollow channel 211 and then extends into the second hollow channel 221. The outer wall of the inserting portion 233 is in contact with the inner wall of the second hollow channel 221, and a first groove 234 that is recessed inward is provided on the outer wall of the inserting portion 233. A first ventilation gap 235 is formed between the first groove 234 and the inner wall of the second hollow channel 221.

[0053] Specifically, when the high-speed airflow flows back upward, the high-speed airflow provides an upward force on the first valve body 21, causing the first valve body 21 to move upward, and the first surrounding wall 212 leaves the bottom wall of the sealing groove 232 and forms an air gap with the sealing groove 232. The high-speed airflow enters the first hollow channel 211 through the air gap and flows into the second hollow channel 221 through the first ventilation gap 235. The first ventilation gap 235 is a narrow gap, and the first ventilation gap 235 plays a role of boosting, so that the high-speed airflow produces smaller atomized particles, thereby improving the atomization effect.

[0054] In one embodiment, Figures 1 to 3 As shown, the atomization assembly also includes a first elastic member 4, a limiting member 8 and a second elastic member 5. The first elastic member 4 is located between the fixing member 23 and the liquid inlet portion 12, and the first elastic member 4 is suitable for providing a rebound force for the fixing member 23. The limiting member 8 is fixed to one end of the first accommodating chamber 11 away from the liquid inlet portion 12. A blocking member 223 is provided on the second valve body 22, and the limiting member 8 is used to limit the movement stroke of the blocking member 223. The second elastic member 5 is located between the blocking member 223 and the first valve body 21, and the second elastic member 5 is suitable for providing a rebound force for the blocking member 223.

[0055] Specifically, a first step 111 is provided on the cavity wall at the bottom of the first accommodating cavity 11, and the first step 111 is located on the upper side of the liquid inlet portion 12. During the process of compressing the gas, one end of the first elastic member 4 contacts the first step 111, and the other end of the first elastic member 4 contacts the fixing member 23. When the compression assembly 2 moves downward under the action of the first external force, the fixing member 23 compresses the first elastic member 4 to cause the first elastic member 4 to deform. When the first external force is removed, the first elastic member 4 restores the elastic deformation and provides a rebound force to the fixing member 23, so that the fixing member 23 moves upward. During the upward movement of the fixing member 23, the first valve body 21 and the second valve body 22 are driven to move upward together.

[0056] Furthermore, a second step 112 is provided on the cavity wall at the top of the first accommodating cavity 11, and the limiting member 8 is fixed on the second step 112. A blocking member 223 is fixedly connected to the second valve body 22, and the blocking member 223 is located below the limiting member 8. The second elastic member 5 is located between the blocking member 223 and the first valve body 21. One end of the second elastic member 5 contacts the first valve body 21, and the other end contacts the blocking member 223. When the second valve body 22 moves downward under the action of the first external force, the blocking member 223 compresses the second elastic member 5 to cause the second elastic member 5 to deform. When the first external force is removed, the second elastic member 5 restores the elastic deformation and provides a rebound force to the blocking member 223, so that the second valve body 22 moves upward. When the blocking member 223 moves upward, it will contact the limiting member 8. The limiting member 8 is used to limit the movement stroke of the blocking member 223 to prevent the second valve body 22 from separating from the atomization bin 1.

[0057] In one embodiment, Figures 1 to 4 As shown, the atomization assembly also includes a plugging member 6, the liquid inlet portion 12 includes a liquid inlet cavity 121, the plugging member 6 is arranged in the liquid inlet cavity 121, the size of the plugging member 6 is adapted to the liquid inlet cavity 121, the shape of the plugging member 6 is not limited, the plugging member 6 can be spherical, cylindrical or other shapes, preferably, the plugging member 6 is a spherical structure, when the plugging member 6 is in the first position, the plugging member 6 is in sealing contact with the cavity wall of the liquid inlet cavity 121, the atomized liquid in the liquid inlet cavity 121 cannot flow to the first accommodating cavity 11, and the liquid inlet portion 12 and the first accommodating cavity 11 are closed and blocked; when the compression assembly 2 compresses the gas in the first accommodating cavity 11 downward, the first accommodating cavity 11 generates a downward movement The airflow moving downward acts on the blocking member 6, so that the blocking member 6 moves upward from the first position to the second position. When the blocking member 6 moves to the second position, a liquid inlet gap is formed between the blocking member 6 and the cavity wall of the liquid inlet cavity 121. The atomized liquid flows into the first accommodating cavity 11 through the liquid inlet gap. The liquid inlet portion 12 is connected to the first accommodating cavity 11. When the compression component 2 moves back, the upward high-speed airflow generated is mixed with the atomized liquid in the first accommodating cavity 11 and atomizes the atomized liquid into fine droplets. At this time, the air pressure in the liquid inlet cavity 121 gradually decreases, and the blocking member 6 falls back to the first position under the action of its own gravity, and re-blocks the liquid inlet cavity 121.

[0058] In one embodiment, Figure 3 , Figure 7 and Figure 8As shown, the nozzle assembly 3 includes a support 31 and a nozzle 32. The support 31 is provided with a first mounting portion 311 and a second mounting portion 312. The first mounting portion 311 is arranged below the second mounting portion 312. The first mounting portion 311 is provided with a first mounting cavity 3111 with an opening facing downward, and the second mounting portion 312 is provided with a second mounting cavity 3121 with an opening facing upward. The upper end of the second valve body 22 is fixed in the first mounting cavity 3111. When the support 31 is pressed, the support 31 drives the second valve body 22 to move downward together.

[0059] Specifically, a second ventilation gap 313 is left between the inner wall of the first installation cavity 3111 and the outer wall of the second valve body 22. A first through hole 222 is provided at the upper end of the second valve body 22. The first through hole 222 is located in the first installation cavity 3111. The second hollow channel 221 is connected to the second ventilation gap 313 through the first through hole 222. The second ventilation gap 313 is a narrow gap. The second ventilation gap 313 plays a role of pressurization, so that the high-speed airflow produces smaller atomized particles, thereby improving the atomization effect.
