Description

Technical Field

[0001] This invention relates to the field of aerosol generation equipment technology, and in particular to an atomizing component and its aerosol forming apparatus. Background Technology

[0002] Aerosol generators are products that generate aerosols by heating an atomizing liquid with an atomizer. Due to their ease of use and the fact that the flavor can be changed by adjusting the atomizing liquid, they have been widely and rapidly promoted in domestic and international markets in recent years.

[0003] Currently available aerosol generators typically include an atomizing component, which consists of a mouthpiece, an airway tube, and an atomizing support. The atomizing support has an atomizing airway, with one end of the airway tube connected to the mouthpiece and the other end connected to the atomizing airway. Figure 5 The image shows that a large amount of condensate in the airway tube was not drained from the airway tube in time, but accumulated in large quantities at the mouth of the second end of the airway tube or at the mouth of the atomizing channel. When the user inhales, the large amount of accumulated condensate is sucked into the user's mouth through the mouthpiece along the inner wall of the airway tube, which seriously affects the product experience and poses a health risk. Summary of the Invention

[0004] The purpose of this invention is to provide an atomizing component and its aerosol forming device, which aims to solve the technical problem that the condensate of existing aerosol generating devices is sucked into the user's mouth through the mouthpiece along the inner wall of the airway tube, seriously affecting the product experience and posing health risks.

[0005] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides an atomizing assembly, which includes a mouthpiece, an airway tube, and an atomizing support. The atomizing support is provided with an atomizing airway. A first end of the airway tube is connected to the mouthpiece, and a second end of the airway tube is connected to the atomizing airway. A flow guiding structure is provided within the atomizing support and / or the airway tube. The flow guiding structure is configured to guide condensate on the atomizing support and / or within the airway tube to disperse away from the mouthpiece; and / or, the flow guiding structure is configured to guide the airflow at the second end of the airway tube and / or within the airway tube to converge radially inward.

[0006] In some embodiments, the atomizing support has an arc-shaped structure on the side of the airway tube away from the mouthpiece, and the flow guiding structure is a raised rib provided on the arc-shaped structure and protruding towards the second end of the airway tube, with the top of the raised rib gradually extending radially inward toward the airway tube.

[0007] In some embodiments, the top of the protruding bony protrusion is located outside the airway tube or extends into the airway tube, and the distance between the protruding bony protrusion and the inner wall of the airway tube is not greater than the radius of the airway tube.

[0008] In some implementations, there is at least one protruding bone.

[0009] In some implementations, the axis of the protruding bone is a straight line, a two-dimensional curve, or a three-dimensional curve.

[0010] In some embodiments, an atomizing chamber is provided on the side of the arc-shaped structure away from the mouthpiece on the atomizing support. The atomizing chamber is connected to the space of the arc-shaped structure facing the mouthpiece to form an atomizing airway.

[0011] In some embodiments, a mounting base is provided inside the atomizing chamber, and a heating liquid guiding component is provided on the mounting base.

[0012] According to another aspect of this application, embodiments of the present invention also provide an aerosol forming apparatus, which includes a housing and an atomizing component as described above, with a nozzle constructed at one end of the housing, and an airway tube and an atomizing support both disposed within the housing.

[0013] In some embodiments, when the atomizing assembly includes an atomizing chamber and a heating liquid guiding component, the housing has an internal structure with a liquid storage chamber that is connected to the atomizing chamber; or, the heating liquid guiding component extends into the liquid storage chamber.

[0014] In some embodiments, a base is provided at the end of the outer shell away from the nozzle, an air inlet is provided on the base to communicate with the atomizing chamber, a liquid suction component is provided inside the base, and an electrode pin is provided on the base to communicate with the heating liquid guiding component.

[0015] Compared with the prior art, the atomizing component of the present invention has at least the following beneficial effects:

[0016] This invention discloses an atomizing assembly, which includes a mouthpiece, an airway tube, and an atomizing support. The atomizing support has an atomizing airway. A first end of the airway tube is connected to the mouthpiece, and a second end of the airway tube is connected to the atomizing airway. Because a large amount of condensate in the airway tube is not promptly drained and accumulates at the opening of the second end of the airway tube, this invention addresses this issue by providing a flow-guiding structure within the atomizing support and / or the airway tube. This flow-guiding structure is configured to guide the flow on the atomizing support and / or within the airway tube. The condensate is dispersed away from the mouthpiece, allowing a large amount of condensate accumulated on the atomizing support and / or inside the airway tube to be discharged from the airway tube in a timely manner; and / or, the flow guiding structure is configured to guide the airflow at the second end of the airway tube and / or inside the airway tube to converge radially inward, preventing the suction airflow from carrying the large amount of condensate accumulated at the second end of the airway tube or inside the airway tube towards the mouthpiece; therefore, the flow guiding structure can drain liquid in a timely manner, prevent accumulation, improve the product experience, and reduce the health risks of inhalation for users.

[0017] On the other hand, the aerosol forming apparatus provided by the present invention is designed based on the above-mentioned atomizing component, and its beneficial effects are the same as those of the above-mentioned atomizing component, which will not be repeated here.

[0032] Example 1

[0033] like Figure 1-7 As shown, this embodiment of the invention provides an atomizing component, which includes a mouthpiece 11, an airway tube 2, and an atomizing support 3. The atomizing support 3 is provided with an atomizing airway. The first end of the airway tube 2 is connected to the mouthpiece 11, and the second end of the airway tube 2 is connected to the atomizing airway. A flow guiding structure is provided in the atomizing support 3 and / or the airway tube 2. The flow guiding structure is configured to guide the condensate on the atomizing support 3 and / or in the airway tube 2 to disperse away from the mouthpiece 11; and / or, the flow guiding structure is configured to guide the airflow at the second end of the airway tube 2 and / or in the airway tube 2 to converge radially inward.

[0034] In this embodiment, as Figure 5-7 The diagram shown is a structural diagram of the connection between the second end of the airway tube 2 and the atomizing airway. Figure 5The diagram shows that a large amount of condensate in the airway tube 2 was not drained from the airway tube 2 in a timely manner, but accumulated in large quantities at the opening of the second end of the airway tube 2 or at the opening of the atomizing channel. When the user inhales, the large amount of accumulated condensate is drawn into the user's mouth through the mouthpiece 11 along the inner wall of the airway tube 2, seriously affecting the product experience and posing a health risk; Figure 6-7 As shown, this embodiment features a flow-guiding structure within the atomizing support 3 and / or the airway tube 2. This flow-guiding structure is configured to guide the condensate accumulated on the atomizing support 3 and / or in the airway tube 2 away from the mouthpiece 11, ensuring that a large amount of condensate on the atomizing support 3 and / or in the airway tube 2 is promptly discharged from the airway tube 2. Alternatively, the flow-guiding structure is configured to guide the airflow at the second end of the airway tube 2 and / or within the airway tube 2 to converge radially inward, preventing the suction airflow from driving the large amount of condensate accumulated at the second end of the airway tube 2 and / or within the airway tube 2 towards the mouthpiece 11. Therefore, this flow-guiding structure can drain liquid promptly, prevent accumulation, improve the product experience, and reduce the health risks associated with user inhalation.

[0035] In some embodiments, the atomizing support 3 has an arc-shaped structure 31 on the side of the airway tube 2 away from the mouthpiece 11. The guiding structure is a raised rib 32 provided on the arc-shaped structure 31 and protruding towards the second end of the airway tube 2. At the same time, the top of the raised rib 32 gradually extends radially inward towards the airway tube 2, so that the raised rib 32 extends from the arc-shaped structure 31 towards the second end of the airway tube 2. While extending, the top of the raised rib 32 gradually extends radially inward towards the airway tube 2. Due to the protrusion... The rib 32 has an adhesive effect with the condensate. Under the action of gravity, the condensate will flow downward with the rib 32. Therefore, the rib 32 can guide the large amount of condensate accumulated at the mouth of the second end of the airway tube 2 or the mouth of the atomizing channel to move downward. At the same time, it prevents the suction airflow from carrying the large amount of condensate accumulated at the mouth of the second end of the airway tube 2 or the mouth of the atomizing channel to move towards the mouthpiece 11. This flow guiding structure can drain the liquid in time, prevent accumulation, improve the product experience, and reduce the health risks of inhalation.

[0036] In some embodiments, the top of the protruding bony part 32 is located outside the airway tube 2 or extends into the interior of the airway tube 2, and the distance between the protruding bony part 32 and the inner wall of the airway tube 2 is not greater than the radius of the airway tube 2, such as... Figure 7As shown, the distance between the protruding bone 32 and the inner wall of the airway tube 2 is H in the figure. When the distance between the protruding bone 32 and the inner wall of the airway tube 2 is small, a small capillary guide gap can be formed between the protruding bone 32 and the inner wall of the airway tube 2. The capillary guide force formed by the capillary guide gap quickly guides the large amount of condensate accumulated at the mouth of the second end of the airway tube 2 or the mouth of the atomization channel to move downward. The protruding bone 32 can drain the liquid in time, prevent accumulation, improve the product experience, and reduce the health risks of users inhaling.

[0037] In some embodiments, there is at least one protruding bone position 32. Specifically, the number of protruding bone positions 32 can be one or more, such as... Figure 6-7 As shown, there are two raised bony positions 32, and the two raised bony positions 32 are symmetrically arranged on the left and right. The two raised bony positions 32 can guide the airflow at the mouth of the second end of the airway tube 2 to converge radially inward, preventing the suction airflow from carrying the large amount of condensate accumulated at the mouth of the second end of the airway tube 2 to move towards the mouthpiece 11. At the same time, the opposite parts of the two raised bony positions 32 form a capillary guide gap with the inner wall of the airway tube 2, thus accelerating the drainage of liquid, preventing accumulation, improving the product experience, and reducing the health risks of users inhaling.

[0038] In some embodiments, the axis 321 of the protruding rib 32 is a straight line, a two-dimensional curve, or a three-dimensional curve, as long as it can guide the condensate. Figure 6-7 As shown, the cross-section of the protruding bone position 32 can be of any shape, the size of the protruding bone position 32 can be of any size, and it can be fixed or varied along the axis 321.

[0039] In some embodiments, an atomizing chamber is provided on the side of the arc-shaped structure 31 away from the mouthpiece 11 on the atomizing support 3. The atomizing chamber is connected to the space of the arc-shaped structure 31 facing the mouthpiece 11 to form an atomizing air passage. The condensate can be guided into the atomizing chamber through the protruding rib 32 and the arc-shaped structure 31 in sequence, which can atomize the condensate a second time and improve the utilization rate.

[0040] In some embodiments, a mounting base 33 is provided inside the atomizing chamber, and a heating liquid guiding component 34 is provided on the mounting base 33, which can heat the condensate.

[0041] Example 2

[0042] This invention also provides an aerosol forming device, which includes a housing 1 and the atomizing component of Embodiment 1. The nozzle 11 is constructed at one end of the housing 1, and the airway tube 2 and the atomizing support 3 are both disposed inside the housing 1.

[0043] In some embodiments, when the atomizing assembly includes an atomizing chamber and a heating liquid guiding component 34, the inner structure of the outer casing 1 includes a liquid storage chamber 12, which is filled with atomizing liquid, such as... Figure 1 and 4 As shown, a sealing silicone 121 is provided inside the outer shell 1 to form a liquid storage chamber 12, which is connected to the atomizing chamber; or, a heating liquid guiding element 34 extends into the liquid storage chamber 12. The heating liquid guiding element 34 can be a porous ceramic heating element, which can guide the atomized liquid in the liquid storage chamber 12 to the heating liquid guiding element 34 in the atomizing chamber, and heat the atomized liquid through the heating liquid guiding element 34 to produce aerosol for the user to inhale.

[0044] In some embodiments, a base 4 is provided at the end of the outer shell 1 away from the nozzle 11. A sealing ring 5 can be provided between the base 4 and the inner wall of the outer shell 1 for sealing. An air inlet 41 communicating with the atomizing chamber is provided on the base 4. A liquid suction element 42 is provided inside the base 4 to absorb the condensate flowing into the base 4. An electrode pin 43 communicating with the heating liquid guiding element 34 is provided on the base 4. The electrode pin 43 is connected to the battery cell to supply power to the heating liquid guiding element 34.

[0045] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
