[0030] The atomizing device and atomizing equipment provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0031] like Figures 1 to 5As shown in the embodiment of this application, an atomizing device is proposed, including an atomizing core 1, a housing 2, a liquid guiding component 6, and a sleeve 3; the housing 2 has a receiving cavity, the sleeve 3 is disposed in the receiving cavity, and there is a space between the sleeve 3 and the housing 2 to form a liquid storage cavity 4; the liquid guiding component 6 is disposed in the sleeve 3, the liquid guiding component 6 is arranged in a ring, and the inner circumferential surface of the liquid guiding component 6 surrounds to form an atomizing channel 5, and the atomizing core 1 is disposed in the atomizing channel 5; the sleeve 3 is provided with a connecting hole, the connecting hole connecting the liquid guiding component 6 and the liquid storage cavity 4.

[0032] In this embodiment, the sleeve 3 is placed in the receiving cavity, and a space exists between the sleeve 3 and the housing 2 to form a liquid storage cavity 4. A liquid guide 6 is disposed in the sleeve 3, and the liquid guide 6 is annularly arranged, with its inner circumferential surface forming an atomizing channel 5. The atomizing core 1 is disposed in the atomizing channel 5. The sleeve 3 has a connecting hole that connects the liquid guide 6 and the liquid storage cavity 4. In this way, the atomized liquid in the liquid storage cavity 4 first flows into the liquid guide 6 through the connecting hole, and then is supplied to the atomizing core 1 at a uniform speed through the liquid guide 6, resulting in a stable liquid supply rate and reducing the risk of leakage.

[0033] Furthermore, the liquid guiding component 6 adopts a ring structure, with its inner circumferential surface forming an atomization channel 5, allowing the atomized liquid to permeate evenly into the atomizing core 1 along the ring circumference. Compared to a single-sided liquid guiding design, this structure disperses the liquid guiding pressure, avoids local oversaturation, and further reduces the risk of leakage.

[0034] It should be noted that the sleeve 3 refers to a cylindrical structural component with a hollow cavity. The liquid guiding component 6 can be placed in the hollow cavity of the sleeve 3. The cross-sectional shape of the sleeve 3 can be circular, elliptical, etc. The structure of the sleeve can be a straight cylinder with the same size at the top and bottom, or a variable cross-section cylinder with different sizes at the top and bottom. In addition, the sleeve 3 can be made of stainless steel pipe, copper pipe, plastic pipe, etc. At least part of the diameter of the sleeve 3 is smaller than the diameter of the shell 2 to form the space.

[0035] For example, such as Figures 1 to 4 As shown, sleeve 3 can be composed of two sub-sleeves of different diameters, or as shown in the figure. Figure 5 As shown, the sleeve 3 can be formed as a steel pipe with a constant diameter, and a connecting hole is provided on the side wall of the steel pipe. The size and location of the connecting hole are not limited in this embodiment.

[0036] In some embodiments, the atomizing device has an air inlet end that is connected to the atomizing channel 5 and is used to supply air to the atomizing channel 5. Eight air inlets 11 are provided on the side wall of the sleeve 3 near the air inlet end. The atomized liquid is fed more evenly through the eight air inlets 11, thereby improving the atomized taste.

[0037] In some embodiments, the atomizing core 1 includes a fixed bracket, a liquid-guiding cotton, and a heating wire; the fixed bracket is fixed in the atomizing channel 5, the liquid-guiding cotton is disposed in the fixed bracket, and the heating wire is disposed in the liquid-guiding cotton. In this way, the atomized liquid in the liquid storage chamber 4 first flows through the liquid guiding component 6, and then flows through the liquid-guiding cotton of the atomizing core 1. That is, a gradient liquid guiding path is formed through the double isolation of the liquid guiding component 6 and the liquid-guiding cotton, which effectively slows down the flow speed of the atomized liquid and improves the stability of the liquid supply.

[0038] In addition, the atomizing core 1 can be a pre-made heating core, which has a simple assembly process and effectively reduces the production cost of the atomizing device.

[0039] It should be noted that the liquid guiding component 6 can be made of porous ceramic or modified glass fiber, and the porosity is controlled within the range of 0-50%. At the same time, the diameter of the connecting holes is matched to form a dual flow-limiting structure, ultimately achieving synergistic optimization of stable liquid supply and leakage prevention.

[0040] Optionally, such as Figures 1 to 4 As shown, the axial direction of the sleeve 3 is the first direction X. The sleeve 3 includes a first sub-sleeve 31 and a second sub-sleeve 32 connected to each other along the first direction X. The housing 2 has an air outlet at one end along the first direction X. The end of the second sub-sleeve 32 away from the first sub-sleeve 31 is connected to the end of the housing 2 with the air outlet. The first sub-sleeve 31 has a first cavity, and the second sub-sleeve 32 has a second cavity. The cross-sectional area of ​​the first sub-sleeve 31 is larger than the cross-sectional area of ​​the second sub-sleeve 32 along the first direction X. The liquid guide 6 is disposed in the first cavity. The atomizing channel 5 formed by the liquid guide 6 is connected to the second cavity, and the second cavity is connected to the air outlet.

[0041] It should be noted that, as Figure 1 As shown, the second direction Y is perpendicular to the first direction X.

[0042] In this embodiment, the sleeve 3 has its axis oriented in the first direction X. The sleeve 3 includes a first sub-sleeve 31 and a second sub-sleeve 32 connected to each other along the first direction X. One end of the housing 2 along the first direction X has an air outlet, and the end of the second sub-sleeve 32 away from the first sub-sleeve 31 is connected to the end of the housing 2 with the air outlet. The first sub-sleeve 31 has a first cavity, and the second sub-sleeve 32 has a second cavity. Perpendicular to the first direction X, the cross-sectional area of ​​the first sub-sleeve 31 is larger than the cross-sectional area of ​​the second sub-sleeve 32. A liquid guide 6 is disposed within the first cavity, and the atomizing channel 5 formed by the liquid guide 6 communicates with the second cavity, which in turn communicates with the air outlet. Thus, by setting the cross-sectional area of ​​the first sub-sleeve 31 to be larger than that of the second sub-sleeve 32, the atomizing device can balance the liquid supply speed and the capacity of the liquid storage chamber 4.

[0043] Specifically, if the first sub-sleeve 31 is selected from the sub-sleeve 3 with the same diameter as the second sub-sleeve 32, the liquid supply speed may be uneven as the liquid volume in the liquid storage chamber 4 decreases; if the second sub-sleeve 32 is selected from the sub-sleeve 3 with the same diameter as the first sub-sleeve 31, the space occupied by the sleeve 3 will be too large, thereby affecting the liquid storage capacity of the liquid storage chamber 4.

[0044] Furthermore, the large diameter design of the first sub-sleeve 31 results in a greater circumferential length of its inner wall, providing a wider contact surface for the annular liquid guide 6. This ensures uniform penetration of the atomized liquid along the entire circumference of the liquid guide 6, preventing localized insufficient or oversaturated liquid supply. Moreover, the second sub-sleeve 32 serves as a transition section 33 connecting the atomization channel 5 to the external airflow. Its diameter is smaller than that of the first sub-sleeve 31, forming a constricted structure that can prevent backflow of liquid caused by negative pressure suction when atomization stops.

[0045] In addition, the first sub-sleeve 31 serves as the core area for liquid storage and guiding, providing a stable supply; the second sub-sleeve 32 serves as the atomization and airflow acceleration area, forming a Venturi effect through changes in cross-sectional area to improve atomization efficiency.

[0046] Optionally, such as Figure 2 and Figure 4 As shown, the connecting hole includes a first hole 7, which is located at one end of the first sub-sleeve 31 near the second sub-sleeve 32, and the first hole 7 penetrates the first sub-sleeve 31 along the first direction X.

[0047] In this embodiment, the first hole 7 is located at one end of the first sub-sleeve 31 near the second sub-sleeve 32, and the first hole 7 penetrates the first sub-sleeve 31 along the first direction X. In this way, the first hole 7 forms a straight liquid guiding channel through the axial direction, so that the atomized liquid flows along the axial direction of the sleeve 3 instead of radially diffusing, eliminating the problem of uneven circumferential distribution of the atomized liquid caused by centrifugal force or gravity, and reducing the liquid guiding path deviation rate.

[0048] Optionally, such as Figure 2 and Figure 4 As shown, the connecting hole also includes a second hole 8, which is located at the end of the first sub-sleeve 31 away from the second sub-sleeve 32, and the second hole 8 penetrates the first sub-sleeve 31 along a direction perpendicular to the first direction X.

[0049] In this embodiment, by placing the second hole 8 at the end of the first sub-sleeve 31 away from the second sub-sleeve 32, the second hole 8 penetrates the first sub-sleeve 31 along a direction perpendicular to the first direction X. This achieves uniform circumferential liquid supply through radial diffusion of the atomized liquid. Furthermore, the radially penetrating second hole 8, in conjunction with the axially penetrating first hole 7, enables uniform liquid supply to the guiding cotton in both the radial and axial directions.

[0050] Optionally, such as Figure 3 and Figure 4As shown, there is a first space between the outer peripheral surface of the first sub-sleeve 31 and the shell 2, and a second space between the outer peripheral surface of the second sub-sleeve 32 and the shell 2. The first space and the second space are connected to form a liquid storage cavity 4.

[0051] In this embodiment, a first space is provided between the outer peripheral surface of the first sub-sleeve 31 and the housing 2, and a second space is provided between the outer peripheral surface of the second sub-sleeve 32 and the housing 2. The first and second spaces are connected to form a liquid storage chamber 4. In this way, the liquid automatically balances the liquid level difference through the interface between the first and second spaces, eliminating the problem of unilateral liquid shortage caused by tilting and improving the utilization rate of the atomizing liquid. It should be noted that the interface between the first and second spaces refers to the connection point between the first sub-sleeve 31 and the second sub-sleeve 32.

[0052] In addition, connecting holes can be provided on the outer peripheral surface and top surface of the first sub-sleeve 31 to increase the liquid supply speed and uniformity while ensuring the stability of the liquid supply.

[0053] Optionally, such as Figure 1 and Figure 2 As shown, the first sub-sleeve 31 is fitted to the inner wall of the shell 2, and a third space exists between the second sub-sleeve 32 and the shell 2 to form a liquid storage cavity 4.

[0054] In this embodiment, the first sub-sleeve 31 is fitted to the inner wall of the housing 2, and a third space is provided between the second sub-sleeve 32 and the housing 2 to form a liquid storage cavity 4. In this way, a rigid connection can be formed between the first sub-sleeve 31 and the inner wall of the housing 2 through interference fit or bonding process, which improves the overall vibration resistance of the sleeve 3 and avoids the displacement of the liquid guiding path caused by vibration.

[0055] In addition, a connecting hole extending along the first direction X can be provided on the top surface of the first sub-sleeve 31. The atomizing liquid can be directly transported to the bottom of the liquid guiding component 6 through the connecting hole extending along the first direction X, thereby shortening the liquid guiding path and improving the liquid guiding efficiency.

[0056] Optionally, such as Figure 1 and Figure 3 As shown, it also includes a first sealing element 9; the sleeve 3 also includes a transition section 33, which connects the first sub-sleeve 31 and the second sub-sleeve 32. The atomizing core 1 extends into the transition section 33, and there is a fourth space between the atomizing core 1 and the transition section 33. The first sealing element 9 is disposed in the fourth space to seal the transition section 33 and the atomizing core 1.

[0057] In this embodiment, a transition section 33 connects the first sub-sleeve 31 and the second sub-sleeve 32. The atomizing core 1 partially extends into the transition section 33, and a fourth space exists between the atomizing core 1 and the transition section 33. A first sealing member 9 is disposed in the fourth space to seal the transition section 33 and the atomizing core 1. This ensures complete isolation between the airflow in the atomization channel 5 and the liquid guiding member 6, preventing backflow of the atomized liquid due to negative pressure backflow and reducing the leakage rate.

[0058] In some embodiments, the first seal 9 is made of at least one of silicone, rubber, plastic sealing material, metallic sealing material, or composite material. The rubber includes nitrile rubber, fluororubber, or silicone rubber; the plastic sealing material includes polytetrafluoroethylene or polyurethane; and the metallic sealing material includes copper, aluminum, or nickel-based alloys.

[0059] like Figure 1 and Figure 3 As shown, the shape of the first seal 9 is designed according to the shape of the inner wall of the transition section 33; exemplarily, the first seal 9 can be configured as follows: Figure 1 The circular shape shown can be set as follows: Figure 3 The shape is a round cap.

[0060] Optionally, such as Figure 1 , Figure 3 and Figure 5 As shown, it also includes a sealing seat 10; one end of the housing 2 is provided with an air outlet, one end of the sleeve 3 is connected to the end of the housing 2 where the air outlet is provided, and the atomizing channel 5 is connected to the air outlet; the sealing seat 10 is sealed at the end of the sleeve 3 away from the air outlet, the sealing seat 10 is connected to the housing 2, and the sealing seat 10 is provided with an air inlet 11, which is connected to the atomizing channel 5.

[0061] In this embodiment, an air outlet is provided at one end of the housing 2, and one end of the sleeve 3 is connected to the end of the housing 2 with the air outlet. The atomizing channel 5 communicates with the air outlet. A sealing seat 10 is placed at the end of the sleeve 3 away from the air outlet. The sealing seat 10 is connected to the housing 2 and has an air inlet 11 that communicates with the atomizing channel 5. This allows the sealing seat to block the end of the sleeve 3 away from the air outlet and, together with the first sealing element 9, forms a double sealing system, ensuring the sealing performance of the atomizing channel 5, blocking the leakage path, and further reducing the leakage rate.

[0062] In some embodiments, such as Figure 1As shown, the sealing seat 10 has a first groove, and at least part of the housing 2 extends into the first groove; the atomizing device also includes a third sealing element 13, which is disposed between the groove wall of the first groove and the housing 2, and is used to seal the gap between the groove wall of the first groove and the housing 2; in addition, the third sealing element 13 is also disposed between the sleeve 3 and the sealing seat 10 to seal the sleeve 3 and the sealing seat 10.

[0063] In some embodiments, such as Figure 3 As shown, the sealing seat 10 is disposed in the sleeve 3, and the sealing seat 10 has a concave-convex structure on the outer side facing the sleeve 3 to increase the sealing between the sleeve 3 and the sealing seat 10; in addition, the atomizing device also includes a fourth sealing member 14. The sleeve 3 is provided with a second groove, at least part of the housing 2 extends into the second groove, and the fourth sealing member 14 is disposed between the groove wall of the second groove and the housing 2. The fourth sealing member 14 is used to seal the gap between the groove wall of the second groove and the housing 2.

[0064] Optionally, such as Figure 1 , Figure 3 and Figure 5 As shown, the inner wall of the housing 2 is provided with an installation groove around the air outlet, and the sleeve 3 extends at least partially into the installation groove. A sealing structure is provided between the groove wall of the installation groove and the sleeve 3 to seal the gap between the sleeve 3 and the groove wall.

[0065] In this embodiment, the mounting groove surrounds the air outlet, and the sleeve 3 extends at least partially into the mounting groove. A sealing structure is provided between the groove wall and the sleeve 3 to seal the gap between the sleeve 3 and the groove wall. This prevents the atomizing liquid from permeating from the internal liquid storage chamber 4 to the external environment through the sealing structure, while also preventing external dust and moisture from reversibly intruding into the atomizing channel 5 and causing pollution.

[0066] In some embodiments, such as Figure 1 and Figure 3 As shown, the sealing structure can be an annular sealing ring, which is sleeved on the sleeve 3. The inner side of the sealing ring abuts against the sleeve 3, and the outer side of the sealing ring abuts against the groove wall of the mounting groove.

[0067] In some embodiments, such as Figure 1 , Figure 3 and Figure 5As shown, the atomizing device also includes a mouthpiece connected to the housing 2. The mouthpiece has an air outlet, and a fifth sealing element 15 is detachably sealed within the air outlet. The fifth sealing element 15 is detachably connected to the mouthpiece, allowing for insertion and removal. Furthermore, the end of the fifth sealing element 15 has a crimping portion with an outer diameter larger than the diameter of the air outlet, enhancing the sealing effect. During assembly and transportation, and before consumer use, the fifth sealing element 15 is sealed and inserted into the air outlet, preventing liquid leakage from the outlet and affecting product quality before use. When needed, the fifth sealing element 15 can be removed for easy use of the mouthpiece. Therefore, by providing a detachable fifth sealing element 15, the sealing performance of the atomizer is further improved before consumer use, preventing internal liquid leakage.

[0068] Optionally, such as Figure 5 As shown, the sealing structure includes a second sealing element 12; the second sealing element 12 has a sealing groove on the side facing the sleeve 3, and the sleeve 3 is inserted into the sealing groove; the second sealing element 12 has a third hole, which connects the air outlet and the atomizing channel 5.

[0069] In this embodiment, a sealing groove is provided on the side of the second seal 12 facing the sleeve 3, and the sleeve 3 is inserted into the sealing groove; the third hole connects the air outlet and the atomizing channel 5. This insertion design facilitates installation. Furthermore, after being inserted into the groove, the sleeve 3 forms a surface contact sealing interface with the side wall. The deformation of the elastic material compensates for assembly tolerances, maintaining sealing stability under vibration and temperature changes, and preventing the risk of liquid creeping along the outer wall of the sleeve 3.

[0070] In addition, by setting a third hole as a dedicated airflow passage connecting the air outlet and the atomization channel 5, it is completely isolated from the liquid storage chamber 4, avoiding cross-contamination between aerosol and un-atomized liquid, and ensuring atomization purity and consistent taste.

[0071] Optionally, such as Figure 5 As shown, the outer peripheral surface of the second seal 12 is provided with a first protrusion, which abuts against the groove wall of the mounting groove.

[0072] In this embodiment, a first protrusion is provided on the outer peripheral surface of the second seal 12, and the first protrusion abuts against the wall of the mounting groove. In this way, the single-plane seal between the second seal 12 and the wall of the mounting groove is transformed into a multi-stage linear seal, which effectively improves the sealing performance between the liquid guide 6 and the liquid storage cavity 4, prevents the atomized liquid in the liquid storage cavity 4 from entering the liquid guide 6 through the gaps in the mounting groove, and improves the sealing efficiency.

[0073] Optionally, such as Figure 5 As shown, the wall of the sealing groove is provided with a second protrusion, which abuts against the sleeve 3.

[0074] In this embodiment, a second protrusion is provided on the wall of the sealing groove, and the second protrusion abuts against the sleeve 3. In this way, the sealing groove wall and the second sealing member 12 are transformed from a single planar seal to a multi-stage linear seal, avoiding the air outlet in the liquid guide member 6 through the gap channel of the mounting groove, thus improving the sealing efficiency.

[0075] Optionally, embodiments of this application provide an atomizing device, including any of the atomizing devices described in the above embodiments.

[0076] In this embodiment, the sleeve 3 is placed in the receiving cavity, and a space exists between the sleeve 3 and the housing 2 to form a liquid storage cavity 4. A liquid guide 6 is disposed in the sleeve 3, and the liquid guide 6 is annularly arranged, with its inner circumferential surface forming an atomizing channel 5. The atomizing core 1 is disposed in the atomizing channel 5. The sleeve 3 has a connecting hole that connects the liquid guide 6 and the liquid storage cavity 4. In this way, the atomized liquid in the liquid storage cavity 4 first flows into the liquid guide 6 through the connecting hole, and then is supplied to the atomizing core 1 at a uniform speed through the liquid guide 6, resulting in a stable liquid supply rate and reducing the risk of leakage.
