Description

Technical Field

[0001] This utility model relates to the field of atomizing devices, and in particular to a leak-proof atomizer assembly and atomizing device. Background Technology

[0002] Among existing atomization device technologies, liquid atomizers, with their ability to transform liquids into tiny particles and release them into the air, have been widely used in various fields such as medicine, beauty, and aromatherapy. These atomizers not only provide the medical field with an effective means of treating respiratory diseases and improving the respiratory environment, but also bring entirely new experiences to the beauty and aromatherapy industries.

[0003] However, despite the many advantages of nebulizers, they also face some challenges in practical use. The most common problem is liquid leakage. When the nebulizer is not in a vertical position, such as when tilted or broken, the liquid inside the container will flow due to gravity. If the nozzle or return port inside the nebulizer is poorly designed or has poor sealing, liquid may accidentally leak into the nebulization chamber. Once the liquid enters the nebulization chamber, it may further seep out of the chamber and onto the outside of the nebulizer. This not only wastes liquid but can also damage the nebulizer itself, causing contamination, corrosion, or even short circuits, affecting the user experience. More seriously, in critical applications such as medical nebulizers, leaked liquid may pose health risks to patients. Utility Model Content

[0004] The present invention aims to overcome the defect in the prior art where, when the atomizing device is tilted or tipped over, the liquid inside the container leaks from the inside of the atomizing device into the atomizing chamber, and then flows from the atomizing chamber to the outside of the atomizing device, causing liquid leakage.

[0005] The technical solution adopted by this utility model is to provide a leak-proof atomizer assembly, comprising: a container for holding liquid, the container having an opening, and an atomizing assembly covering the opening, the atomizing assembly having a spray nozzle, an air inlet, and an atomizing core, the atomizing assembly including an atomizing chamber, the atomizing core disposed within the atomizing chamber, the spray nozzle and the air inlet communicating with the atomizing chamber, the atomizing chamber being an independent cavity separated from the container, the atomizing core extending into the container and communicating with the container through a liquid suction tube, and a downwardly extending return liquid tube disposed at the bottom of the atomizing chamber and surrounding the liquid suction tube, the inner wall of the return liquid tube forming a gap with the outer wall of the liquid suction tube communicating with the atomizing chamber and the container.

[0006] The suction tube draws liquid from the container to the atomizing core, where it mixes with high-pressure gas supplied from the air inlet to form a mist that is then sprayed out from the nozzle. The return tube returns un-atomized liquid from the atomizing core back to the container through gaps. By employing a surrounding gap structure with return holes, combined with the effects of liquid surface tension and the pressure difference between the inside and outside of the container, a liquid seal is achieved. When the atomizing device is tilted or tipped over, these holes effectively hold the liquid, preventing it from leaking from the inside of the container into the atomizing chamber and then further out of the atomizing device, thus achieving a leak-proof effect for the atomizer when tilted or tipped over.

[0007] Furthermore, the suction tube includes a core tube and an extension tube. The core tube connects to the atomizing core, and the extension tube extends into the container. When the atomizer is tilted or horizontal when tilted, the liquid in the suction tube flows to the empty end, allowing the suction tube to hold more liquid. This causes the air volume inside the container to expand, resulting in a decrease in pressure. Combined with the atmospheric pressure outside the container, this creates a pressure difference, preventing leakage when the atomizer is tilted or tilted, further enhancing the leak-proof effect. Simultaneously, the extension tube is directly inserted below the core tube, ensuring a good seal at the connection point, reducing the risk of liquid leakage, and enhancing its structural stability. This ensures that the suction tube will not deform or be damaged by external forces, effectively preventing liquid leakage from the suction tube and further enhancing the overall leak-proof capability of the suction tube.

[0008] Furthermore, the minimum dimension of the gap width D is set between 0.1-3mm.

[0009] When the gap width D is set to less than 0.1, the excessively narrow gap will cause the liquid to flow too slowly, resulting in the accumulation of unatomized liquid in the atomization chamber, which will lead to leakage.

[0010] When the gap width D is set to be greater than 3mm, the excessively wide gap will cause the flow of the less viscous liquid solution to be too smooth. When the atomizing device is tilted or tipped over, the less viscous liquid in the container is likely to flow out through the excessively wide gap, resulting in leakage.

[0011] Because the gap width is between 0.1-3mm, it can ensure the normal operation of the liquid return in the atomization chamber. At the same time, when the atomization device is tilted or tipped over, the combination of the internal pressure of the container and the surface tension of the liquid allows the gap to hold liquids of different viscosities and prevent them from leaking out of the gap.

[0012] Furthermore, the length L of the return pipe extending downward from the bottom of the atomization chamber is set between 1 and 300 mm.

[0013] When L is less than 80mm, the gap width D is set between 0.1-2mm.

[0014] When L is greater than 80mm, the gap width D is set between 0.15-2.5mm.

[0015] By adjusting the length L of the return pipe extending downwards from the bottom of the atomizing chamber and correspondingly adjusting the gap width D, the path length and complexity of the liquid flowing from the container to the atomizing chamber are increased. When the atomizing device is tilted, due to the increased length L of the return pipe, the liquid in the container will encounter greater resistance as it flows towards the atomizing chamber due to the pressure within the container. At the same time, by adjusting the gap width D to accommodate return pipes of different lengths, the pressure distribution within the container is optimized, ensuring that when the atomizer is tilted or tipped over, the liquid will not exceed the surface tension limit due to excessive pressure difference and leak out from the gap.

[0016] Furthermore, the return pipe may be provided with support ribs distributed between the inner wall of the return pipe and the outer wall of the suction pipe. The support ribs extend along the axial direction of the return pipe, and the number of support ribs may be one or more.

[0017] Alternatively, the gap may have a support point for connecting to the outer wall of the suction tube, and the number of support points may be one or more.

[0018] When multiple support ribs are provided, the multiple support ribs are distributed circumferentially along the inner wall of the return pipe, and the interval d between two adjacent support ribs is between 0.1-3mm.

[0019] By incorporating support ribs or points outside the suction tube / within the gap, the axial position of the suction tube can be fixed, preventing it from moving or deforming within the atomizer assembly. This helps ensure a constant gap width, thus avoiding the risk of liquid leakage due to gap variations. Simultaneously, the presence of support ribs or points reduces the area within the return tube / gap, allowing for more precise control of its width. Even when the atomizer assembly is tilted or tipped over by external forces, surface tension can be effectively used to prevent liquid leakage from the gap.

[0020] Furthermore, a cavity component is provided at the lower part of the atomizing assembly, and a return pipe is located below the cavity component and communicates with it. This allows excess liquid in the atomizing cavity to quickly accumulate in the cavity component and be guided back into the container, reducing liquid retention in the atomizing cavity and preventing liquid from leaking from the atomizing cavity to the outside, thereby reducing the risk of leakage due to liquid accumulation.

[0021] Furthermore, the sidewall of the cavity component extends upward to the atomizing assembly, forming a smoother liquid flow channel. Even if the atomizer assembly is in an unstable state, the un-atomized or insufficiently atomized liquid in the atomizing chamber will be guided by the sidewall to the return pipe and flow back to the container through the gap, thereby reducing the risk of un-atomized liquid leaking from the atomizer core or other openings when the atomizer assembly is in an unstable state.

[0022] Furthermore, the sidewall of the cavity component is at least partially inclined towards the return pipe to form a funnel structure, which allows excess liquid in the atomizing cavity to flow quickly along the sidewall of the funnel structure and be guided back to the container, reducing the retention of liquid in the atomizing cavity and preventing liquid from leaking from the atomizing cavity to the outside, thereby reducing the risk of leakage caused by liquid accumulation.

[0023] An atomizing device employing the above-described leak-proof atomizer assembly includes: a base, an air compressor for providing compressed air, and the aforementioned leak-proof atomizer assembly. The leak-proof atomizer assembly is mounted on the base, and the air compressor is connected to an air inlet, forming a complete and efficient atomizing system.

[0024] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting a return pipe around the suction pipe at the bottom of the atomizing chamber, and forming a gap between the inner wall of the return pipe and the outer wall of the suction pipe, a liquid barrier is formed by the gap and the effects of liquid surface tension and the pressure difference between the inside and outside of the container. This effectively prevents liquid from leaking from the inside of the atomizing device to the atomizing core and then further to the outside of the atomizing device when it is tilted. The suction pipe adopts a combination design of a core tube and an extension tube. The core tube is directly connected to the atomizing core, while the extension tube extends into the inside of the container, ensuring a good seal at the connection and preventing liquid leakage from the connection. It also enhances the structural stability of the suction pipe. Even when the atomizing device is tilted or subjected to external force, the suction pipe can maintain its shape and position, thereby effectively preventing liquid leakage. Support ribs or support points are installed inside the return pipe or in the gap, which not only fixes the axial position of the return pipe and prevents it from deforming or moving, but also ensures that the gap width is constant. When the atomizer assembly is tilted or tipped over by external force, it can effectively use the surface tension of the liquid to prevent the liquid from leaking out of the gap, further improving the leak-proof performance of the atomizer.

[0025] Meanwhile, the lower part of the atomizing chamber is designed as a funnel structure, allowing excess liquid to quickly flow back to the container along the side wall of the funnel structure. This reduces the residence time of liquid in the atomizing chamber and lowers the risk of leakage due to liquid accumulation. The side wall of the chamber component extends from the return pipe to the inside of the opening and upwards along the inside of the opening, forming a smooth liquid guiding channel. This ensures that even if the atomizer assembly is in an unstable state, un-atomized liquid in the atomizing chamber will be guided to the return pipe and flow back to the container through the gap, further reducing the risk of leakage. The chamber component and the return pipe are integrally molded, which not only enhances the connection strength between the two but also simplifies the installation process of the atomizer assembly, making installation more convenient and faster, improving production efficiency, and reducing the risk of leakage due to gaps or improper connections between components.

Detailed Implementation

[0055] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0056] Example 1

[0057] like Figure 1 and Figure 2As shown, this embodiment provides a leak-proof atomizer assembly, including a cylindrical container 100 with a circular opening for holding liquid, and an atomizing component 200 covering the circular opening of the container 100. A sealing ring is disposed between the atomizing component 200 and the container 100. The shape of the container 100 and its opening can be flexibly adjusted and customized according to actual application scenarios or specific needs. The atomizing component 200 and the container 100 are connected by a threaded connection, which can be adjusted to use a snap-fit, convex-groove fit, or adhesive bonding method according to actual needs.

[0058] like Figure 3 and Figure 4 As shown, the atomizing assembly 200 has a cylindrical external shape and includes a spray nozzle 210, an air inlet 220, and an atomizing core 230. The spray nozzle 210 is detachably mounted on the top of the atomizing assembly 200 via screws or plug-in connections. The spray tube is tilted to one side, and the shape of the spray nozzle 210 can be adjusted as needed, such as circular, elliptical, or oblong. The air inlet 220 is located on the side of the atomizing assembly 200 and features a circular design for easy connection to gas delivery devices such as compressors or air pumps. It contains a rubber component with raised stripes to enhance the seal between the component and the gas delivery device. A raised notch on one side of the atomizing assembly 200 is provided for inserting a retaining piece into the rubber component, while a raised gripper on the opposite side facilitates picking up or removing the atomizer.

[0059] An atomizing chamber 240 is formed within the atomizing assembly 200. An atomizing core 230 is disposed within the atomizing chamber 240. A spray nozzle 210 and an air inlet 220 communicate with the atomizing chamber 240. The atomizing chamber 240 is a separate, independent cavity from the container 100. The top of the atomizing core 230 is connected to the spray nozzle 210, and its bottom extends into the container 100 via a suction tube 300, communicating with the container 100. Figure 5 , Figure 6 and Figure 7 , Figure 8 As shown, a downward-extending return pipe 400 is provided at the bottom of the atomizing chamber 240 and around the suction pipe 300. An annular gap 410 is formed between the inner wall of the return pipe 400 and the outer wall of the suction pipe 300, connecting the atomizing chamber 240 and the container 100. Its inner wall is smooth. One-third of the annular gap 410 is connected to the atomizing component 200 for fixation. The upper part of the inner wall of the return pipe 400 is chamfered to facilitate liquid inflow. The gap 410 remains uniform from the middle to the bottom without local expansion or contraction.

[0060] The suction tube 300 consists of two parts: a core tube 310 and an extension tube 320. The core tube 310 is designed as a tubular structure and is connected to the atomizing core 230. The extension tube 320 is also designed as a tubular structure, with the inner diameter of the core tube 310 being larger than the outer diameter of the extension tube 320. The extension tube 320 is inserted below the core tube 310 and extends into the container 100.

[0061] The minimum dimension of the width D of the gap 410 is between 0.1-3mm.

[0062] The length L of the return pipe 400 extending downward from the bottom of the atomizing chamber 240 is between 1 and 300 mm. When L is less than 80 mm, the shorter return path results in a smaller pressure change inside the container 100. Therefore, the width D of the gap 410 is further limited to between 0.1 and 2 mm to ensure that liquid leakage can be effectively prevented even in a small space.

[0063] The length L of the return pipe 400 extending downward from the bottom of the atomizing chamber 240 is between 1 and 300 mm. When L is greater than 80 mm, the pressure inside the container 100 increases accordingly due to the longer return path. In order to maintain stable leak-proof performance, the width D of the gap 410 is appropriately widened to between 0.15 and 2.5 mm to accommodate the longer return path and pressure changes.

[0064] Example 2

[0065] like Figure 9 , Figure 10 and Figure 11 As shown, this embodiment provides another leak-proof atomizer assembly, which has a structure basically the same as the leak-proof atomizer assembly in the first embodiment of this utility model, such as... Figure 12 , Figure 13 and Figure 14 , Figure 15 As shown, the difference lies in that, in this embodiment, the return pipe 400 is provided with one or more support ribs 420, which are distributed and supported between the inner wall of the return pipe 400 and the outer wall of the suction pipe 300, so that the suction pipe 300 is connected and fixed to the atomizing component 200. The support rib 420 can be rectangular or fan-shaped, with one end on the inner wall of the return pipe 400 and the other end on the outer wall of the suction pipe 300, extending axially from the opening of the return pipe 400 of the atomizing core 230 in the atomizing chamber 240 to the bottom of the return pipe 400 at the other end.

[0066] Alternatively, one or more support points 420' may be provided within the gap 410. The support points 420' are connected to the outer wall of the return pipe 400. The support points 420' may be point-shaped or short column-shaped and may only be provided at the opening of the return pipe 400.

[0067] When multiple support ribs 420 or support points 420' are provided, the multiple support ribs 420 or support points 420' are distributed circumferentially along the inner wall of the return pipe 400, forming a stable support network. The interval d between two adjacent support ribs 420 or support points 420' is between 0.1-3mm, which not only further limits the surface area of ​​the return pipe 400, but also ensures that the space between the support ribs 420 is sufficient for smooth liquid return, avoiding the increase in flow resistance caused by excessively dense support ribs 420.

[0068] Example 3

[0069] like Figure 16 As shown, this embodiment provides a third type of leak-proof atomizer assembly, which is basically the same in structure as the leak-proof atomizer assembly in the second embodiment of this utility model, such as... Figure 17 and Figure 18 As shown, the difference lies in that, in this embodiment, an atomizing chamber 240 is formed within the atomizing assembly 200, and the atomizing core 230 is disposed within the atomizing chamber 240. The spray nozzle 210 and the air inlet 220 communicate with the atomizing chamber 240. The atomizing chamber 240 is a separate independent cavity from the container 100. The top of the atomizing core 230 is connected to the spray nozzle 210, and the bottom extends into the container 100 and communicates with the container 100 through a liquid suction tube 300. Figure 19 As shown, the bottom of the atomizing chamber 240 is hollowed out, and an independent cavity component 500 is provided at the lower part of the atomizing chamber 240. The core tube 310 extends into the cavity component 500, as shown. Figure 20 As shown, a return pipe 400 is integrally formed at the bottom of the cavity component 500. At least part of the side wall of the cavity component 500 is inclined towards the return pipe 400 to form a funnel structure. The part inclined towards the return pipe 400 presents a smooth curve or a cone shape. One or more support ribs 420 are provided inside the return pipe 400, distributed and supported between the inner wall of the return pipe 400 and the outer wall of the suction pipe 300. The support ribs 420 can be rectangular or fan-shaped, with one end on the inner wall of the return pipe 400 and the other end on the outer wall of the suction pipe 300. They extend axially from the opening of the return pipe 400 of the atomizing core 230 in the atomizing chamber 240 to the bottom of the return pipe 400 at the other end. The upper part of the inner wall of the return pipe 400 is chamfered to facilitate the flow of liquid. The gap 410 remains uniform from the middle to the bottom, without local expansion or contraction.

[0070] The sidewall of the cavity component 500 is at least partially smooth transitioned from the return pipe 400 to the inside of the opening and extends vertically upward along the inside of the opening. A sealing ring is provided between the atomizing component 200 and the container 100, and an annular notch is provided in the sealing ring. The outer edge of the cavity component 500 is fitted into the sealing ring.

[0071] The suction tube 300 consists of two parts: a core tube 310 and an extension tube 320. The core tube 310 is designed as a tubular structure and is connected to the atomizing core 230. The extension tube 320 is also designed as a tubular structure, with the inner diameter of the core tube 310 being larger than the outer diameter of the extension tube 320. The extension tube 320 is inserted below the core tube 310 and extends into the container 100.

[0072] The minimum dimension of the width D of the gap 410 is between 0.1-3mm.

[0073] like Figure 21 and 22 As shown, the length L of the return pipe 400 extending downward from the bottom of the cavity component 500 is between 1 and 300 mm. When L is less than 80 mm, the shorter return path results in a smaller pressure change inside the container 100. Therefore, the width D of the gap 410 is further limited to between 0.1 and 2 mm to ensure that liquid leakage can be effectively prevented even in a small space.

[0074] The length L of the return pipe 400 extending downward from the bottom of the cavity component 500 is between 1 and 300 mm. When L is greater than 80 mm, the pressure inside the container 100 increases accordingly due to the longer return path. In order to maintain stable leak-proof performance, the width D of the gap 410 is appropriately widened to between 0.15 and 2.5 mm to accommodate the longer return path and pressure changes.

[0075] Example 4

[0076] like Figure 23 and Figure 24 As shown, this embodiment provides a fourth type of leak-proof atomizer assembly, including a cylindrical container 100 with a circular opening for holding liquid, and an atomizing assembly 200 covering the circular opening of the container 100. The shape of the container 100 and its opening can be flexibly adjusted and customized according to actual application scenarios or specific needs. The atomizing assembly 200 and the container 100 are connected by a threaded connection, which can be adjusted to use a snap-fit, convex-groove fit, or adhesive bonding method according to actual needs.

[0077] like Figure 25 and Figure 26 As shown, the atomizing assembly 200 has a spray nozzle 210, an air inlet 220, and an atomizing core 230. The spray nozzle 210 has a rigid conduit inside, which is detachably mounted on the side of the atomizing assembly 200 via structural embedding or other fitting methods. The shape of the spray nozzle 210 can be adjusted according to requirements, such as circular, elliptical, or oblong. The air inlet 220 is located on the side of the other end of the atomizing assembly 200 and features a circular design for easy connection to gas delivery devices such as compressors or air pumps.

[0078] The atomizing assembly 200 has an independent cavity component 500 at its lower part. The atomizing core 230 is disposed inside the cavity component 500. The air inlet 220 connects to the top of the atomizing core 230 to form a downward air outlet. The bottom of the atomizing core 230 extends into the container 100 through a liquid suction tube 300, thus forming an atomizing chamber 240 inside the cavity component 500. The side wall of the cavity component 500 extends vertically upward to the atomizing assembly 200. A return liquid tube 400 is integrally formed at the bottom. The bottom of the cavity component 500 slopes towards the return liquid tube 400 to form a funnel structure. The sloped part has a smooth curve or a conical design.

[0079] like Figure 27 , Figure 28 As shown, the return pipe 400 is provided with one or more support ribs 420 or support points 420', distributed and supported between the inner wall of the return pipe 400 and the outer wall of the suction pipe 300. The support rib 420 can be rectangular or fan-shaped, with one end on the inner wall of the return pipe 400 and the other end on the outer wall of the suction pipe 300. The support rib 420 extends axially along the return pipe 400. The upper part of the inner wall of the return pipe 400 is chamfered to facilitate liquid inflow. The gap 410 remains uniform from the middle to the bottom, without local expansion or contraction. In addition, in this embodiment, the width of the gap, the downward extension length of the return pipe, and the spacing between two adjacent support ribs 420 or support points 420' are the same as in embodiments 1-3 above.

The atomizing device includes a base with a mounting groove on the base that matches the leak-proof atomizer assembly, facilitating the positioning and fixing of the atomizer assembly.

[0082] An air compressor provides compressed airflow, and its output end is connected to the air inlet 220 of the atomizer assembly via a flexible hose or rigid tube. The leak-proof atomizer assembly, as described in any of Examples 1-3, is mounted on a base, with its bottom tightly fitted to the mounting groove of the base, further enhancing overall stability.
