Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or atomizers. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0019] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. Similarly, the steps or actions described in the atomizer description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed.

[0020] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0021] Currently, during the use of atomizers, the high-temperature vapor produced by the atomizer condenses as it flows through the relatively low-temperature mouthpiece channel due to the temperature difference, forming tiny condensation droplets on the inner wall of the mouthpiece. If these condensation droplets accumulate in large quantities in the mouthpiece, they are highly likely to be accidentally inhaled by the user, which not only seriously affects the user experience but also poses a hygiene risk.

[0022] The following are technical solutions to the problem of condensate buildup in the atomizer: (1) Setting up a physical barrier structure: A barrier step is set inside the nozzle to intercept condensed droplets. However, physical barrier structures are generally more complex. This structure often increases the suction resistance. Moreover, it can only passively "block" the condensed droplets and cannot discharge them. After accumulating to a certain extent, it will still block the airway.

[0023] (2) Use absorbent materials: Fill the inside or bottom of the nozzle with highly absorbent materials such as oil-absorbing cotton. However, the absorption capacity of oil-absorbing cotton is limited, and it will become ineffective once saturated, requiring users to clean or replace it frequently, which undoubtedly increases the cost of use and the difficulty of maintenance. More importantly, it is also a passive solution and cannot fundamentally solve the problem of condensate droplet discharge.

[0024] Based on this, this application solves the problem of condensate droplets accumulating in the air guide channel of the atomizer nozzle by setting a micro-surface texture on the inner surface of the air guide channel. The micro-surface texture forms a flow guide channel and intercepts condensate droplets through the "pinning effect". Under the action of the airflow of the user's normal inhalation, the condensate droplets are directionally discharged through the flow guide channel, thereby solving the problem of condensate droplets accumulating in the air guide channel of the nozzle.

[0025] This application provides an atomizer, such as... Figure 1 , Figure 2 and Figure 3As shown. The atomizer 1000 includes a mouthpiece 10 and an atomizing component 20; the mouthpiece 10 is provided with an air guide channel 101, which connects the atomizing component 20 to the outside; the inner surface of the air guide channel 101 is provided with a micro-surface texture 102, which forms a flow guide channel 103. For example, the trajectory formed by the micro-surface texture 102 on the inner surface of the air guide channel 101 is the flow guide channel 103; the atomizer 1000 is also provided with a liquid suction component 301 and / or a liquid collection structure 30, and the flow guide channel 103 connects the liquid suction component 301 and / or the liquid collection structure 30. The condensate droplets generated during the use of the atomizer 1000 can be directed away from the airflow channel 101 along the flow channel 103, for example, discharged to the liquid intake component 301 or the liquid collection structure 30. In this way, after condensate droplets are formed in the airflow channel 101, the condensate droplets can be quickly discharged through the flow channel 103, avoiding being inhaled by the user, improving the user experience, and extending the service life of the atomizer 1000.

[0026] The micro-surface texture 102 in this application refers to a tiny geometric shape with a size at the micrometer or nanometer scale constructed on the surface of a material (such as the inner surface of the air channel 101). Compared with ordinary interception structures, this application embodiment sets a micro-surface texture 102 on the inner surface of the air channel 101. The micro-surface texture 102 intercepts condensed droplets through a "pinning effect." During the "growth" process of the condensed droplets, they generate self-driven motion, which continuously reduces their adhesion to the surface, thereby preventing the accumulation of condensed droplets on the inner surface of the air channel 101 and achieving efficient drainage. The micro-surface texture 102 also allows condensed droplets to quickly merge, migrate, and detach from the surface. This method does not form liquid residue in corners or gaps like ordinary interception structures, but keeps the inner surface of the air channel 101 cleaner. At the same time, the technical solution of this application relies on the micro-surface characteristics, which basically does not increase the suction resistance and has almost no interference with the original use of the atomizer 1000.

[0027] In some embodiments, the micro-surface texture 102 may be pits, protrusions, grooves, etc.; or it may be a flow channel formed by any one or more interconnected pits, protrusions, grooves, and micropores. The flow channel may also form a grid, wherein the width of the flow channel is 10μm-500μm.

[0028] In some embodiments, the liquid-absorbing component 301 may be made of a liquid-absorbing material such as cotton pads or sponges. The liquid-absorbing component 301 or the liquid-collecting structure 30 can store or fix the discharged condensate droplets, preventing backflow even if the atomizer 1000 is shaken.

[0029] In some embodiments, such as Figure 1As shown, the distribution of the micro-surface texture 102 can at least cover the inner surface of the air guide channel 101. In this embodiment, the micro-surface texture 102 is designed to intercept condensate droplets at any position on the wall of the air guide channel 101 as much as possible. No matter where the condensate droplets are initially attached, they will slide down to the position where the micro-surface texture 102 is provided under the action of gravity and be discharged away from the inner surface of the air guide channel 101 along the flow guide channel 103.

[0030] In some embodiments, the micro-surface texture 102 includes a spiral groove extending along the inner surface of the air guide channel 101, the spiral groove forming at least a portion of the flow guide channel 103. Regardless of where the condensate droplets adhere to the wall of the air guide channel 101, they can slide down into the spiral groove under the influence of gravity, be intercepted by the spiral groove, and be directionally discharged away from the inner surface of the air guide channel 101 along the flow guide channel 103.

[0031] In some embodiments, the width of the spiral groove is between 75 μm and 85 μm, and / or the depth of the spiral groove is between 35 μm and 45 μm. The viscosity range of the condensate droplets is known or measurable, so the size of the formed condensate droplets also has a certain range. The spiral groove with a width of 75 μm to 85 μm and / or a depth of 35 μm to 45 μm in this embodiment can better match the size and viscosity of the condensate droplets. For example, the condensate droplets will not exceed the spiral groove or will only exceed it slightly. In this way, the airflow in the air guide channel 101 will not easily blow out the condensate droplets, thereby efficiently discharging the condensate droplets.

[0032] In some embodiments, at least the inner wall surface of the flow channel 103 is provided with an oleophobic coating 104. In this embodiment, the oleophobic coating 104 works in conjunction with the micro-surface texture 102 to reduce the energy threshold for driving the movement of condensate droplets to an extremely low level. Although the centrifugal force or pressure difference generated on the micro-surface texture 102 during normal inhalation by the user is very weak, it is far greater than the greatly reduced energy threshold. Therefore, this weak external force is sufficient to efficiently drive the condensate droplets to move in a directional and high-speed manner and be discharged along the path designed by the micro-surface texture 102, making it difficult for the condensate droplets to adhere to the flow channel 103. The condensate droplets are discharged directionally along the flow channel 103 and can quickly flow into the liquid suction component or liquid collection structure at the rear end, solving the problem of condensate droplet accumulation and inlet in the air guide channel.

[0033] It should be noted that superoleophobic coatings are functional coatings that repel grease through micro / nano structure design and low surface energy materials (such as fluorides).

[0034] In some embodiments, the oleophobic coating 104 comprises a single-layer superoleophobic nanocoating. In some embodiments, the single-layer superoleophobic nanocoating may be a single-layer superhydrophobic nanocoating containing fluorinated silane applied by a sol-gel method.

[0035] In some embodiments, the thickness of the monolayer superoleophobic nanocoating is between 100 nm and 150 nm, and / or the oil contact angle of the surface of the monolayer superoleophobic nanocoating is not less than 90°. This thickness and oil contact angle of the monolayer superoleophobic nanocoating can delay the contact angle between the condensed droplets and the flow channel 103, causing the condensed droplets to form easily rolling spherical droplets on the flow channel 103, thereby reducing the flow resistance of the condensed droplets in the flow channel 103 to a certain extent.

[0036] It should be noted that the thickness of the single-layer superoleophobic nanocoating can be any value between 100nm and 150nm. For example, the thickness of the single-layer superoleophobic nanocoating can be 100nm, 110nm, 120nm, 130nm, 140nm, or 150nm. This application does not impose any limitation on this. The oil contact angle of the surface of the single-layer superoleophobic nanocoating can be any oil contact angle not less than 90° (where 180° is the highest value in the definition of oil contact angle). For example, the oil contact angle of the surface of the single-layer superoleophobic nanocoating can be 90°, 95°, 100°, 110°, 135°, 140°, 150°, 155°, etc. This application does not impose any limitation on this.

[0037] In some embodiments, the oleophobic coating 104 includes a composite superoleophobic nanocoating, which comprises, from the inside out: a deposition layer, a micron-nano sol layer, and a low surface energy layer. The deposition layer enhances the adhesion between the micron-nano sol layer, the low surface energy layer, and the substrate; the micro-nano roughness of the micron-nano sol layer reduces the contact area between grease-containing condensate droplets and the flow channel 103; the low surface energy layer reduces the surface energy, making it difficult for grease-containing condensate droplets to spread within the flow channel 103. In other words, the oleophobic coating 104 gives the flow channel 103 a lotus leaf-like surface with extremely low oil contact angle hysteresis. Specifically, the oleophobic coating 104 can hysteresis, or even reduce, the contact angle between condensate droplets and the flow channel 103 to zero, thereby promoting the formation of easily rolling spherical droplets on the lotus leaf-like surface, reducing the flow resistance of the condensate droplets within the flow channel 103. In some embodiments, the thickness of the composite superoleophobic nanocoating is between 150 nm and 200 nm, and / or the oil contact angle of the surface of the composite superoleophobic nanocoating is not less than 90°. This thickness and oil contact angle of the composite superoleophobic nanocoating can delay or even reduce the contact angle between the condensate droplets and the flow channel 103 to zero, thereby promoting the formation of easily rolling spherical droplets on the flow channel 103, greatly reducing the flow resistance of the condensate droplets in the flow channel 103.

[0038] It should be noted that the thickness of the composite superoleophobic nanocoating can be any value between 150nm and 200nm. For example, the thickness of the composite superoleophobic nanocoating can be 150nm, 155nm, 165nm, 170nm, 180nm, 190nm, or 200nm. This application does not impose any limitation on this. The oil contact angle of the surface of the composite superoleophobic nanocoating can be any oil contact angle not less than 90° (where 180° is the highest value defined in the oil contact angle definition). For example, the oil contact angle of the surface of the composite superoleophobic nanocoating can be 90°, 135°, 145°, 155°, 165°, etc. This application does not impose any limitation on this.

[0039] In some embodiments, the thickness of the deposited layer is between 4 nm and 6 nm; the thickness of the low surface energy layer is between 2 nm and 3 nm. The deposited layer may include an alumina thin film layer; the micron-nano sol layer may include a nano silica particle sol layer; and the low surface energy layer may include a perfluorooctyltrichlorosilane layer. In this embodiment, the oil contact angle can be up to 165°, and it exhibits excellent durability in long-term immersion in e-liquid and airflow scouring tests.

[0040] In some embodiments, the preparation process of the composite superoleophobic nanocoating is as follows: First, a 5 nm alumina film, i.e., a deposition layer, can be deposited on a PC substrate by atomic layer deposition. This deposition layer is mainly used to enhance the adhesion between the subsequent coatings (such as micron-nano sol layers and low surface energy layers) and the substrate. Then, a layer of nano-silica particle sol is coated on the above alumina film layer using a sol-gel method, and after heat treatment, a micron-nano composite structure (micron-nano sol layer) is formed. This micron-nano composite structure is mainly used to reduce the contact area between grease-containing condensate droplets and the flow channel 103. Finally, a perfluorooctyltrichlorosilane molecular layer (e.g., a perfluorooctyltrichlorosilane molecular layer with a thickness of only 2 nm) is chemically grafted onto the surface of the above micron-nano composite structure by plasma-enhanced chemical vapor deposition to form an ultra-low surface energy layer. This low surface energy layer is mainly used to reduce the surface energy, making it difficult for grease-containing condensate droplets to spread within the flow channel 103.

[0041] It should be noted that whether a single-layer superoleophobic nano-coating is applied to the inner wall of the flow channel 103, or a composite superoleophobic nano-coating is applied to the inner wall of the flow channel 103, the purpose is to give the flow channel 103 a lotus leaf-like surface with extremely low oil contact angle hysteresis. This oleophobic coating can delay, or even reduce to zero, the contact angle between condensate droplets and the flow channel 103, thereby causing the condensate droplets to form easily rolling spherical droplets on the aforementioned lotus leaf-like surface. When the user uses the atomizer 1000, with the support of gravity and the flow channel 103, the condensate droplets are more than capable of resisting normal suction. That is, under normal suction, the condensate droplets in the airflow channel 101 can be directionally discharged along the inner wall of the flow channel 103, thereby improving the user experience.

[0042] like Figure 1 , Figure 2 as well as Figure 3 As shown. The nozzle 10 is also provided with a drainage outlet 105. In embodiments with a liquid suction component 301 and a liquid collection structure 30, the drainage outlet 105 connects the guide channel 103 to the liquid suction component 301 and the liquid collection structure 30, and is used to guide droplets to the liquid suction component 301 and the liquid collection structure 30. The liquid suction component 301 can be set inside the liquid collection structure 30. It should be noted that if too much condensed droplet is stored in the liquid collection structure 30, it is easy to overflow when the atomizer 1000 shakes, contaminating other components. After the liquid suction component 301 absorbs the liquid, there will be less likely to be excess condensed droplets overflowing or leaking in the liquid collection structure 30. In an embodiment with a liquid suction component 301, the drainage outlet 105 can be connected to the flow channel 103 to the liquid suction component 301, thereby guiding the condensed droplets to the liquid suction component 301 for absorption; in an embodiment with a liquid collection structure 30, the drainage outlet 105 can be connected to the flow channel 103 to the liquid collection structure 30, thereby guiding the condensed droplets to the liquid collection structure 30 for storage.

[0043] In some embodiments, the inner side of the drainage outlet 105 may also be coated with a single-layer superoleophobic nano-coating or a composite superoleophobic nano-coating, the function and effect of which are the same as those of the single-layer superoleophobic nano-coating or the composite superoleophobic nano-coating in the drainage channel 103, and will not be described in detail here.

[0044] In some embodiments, such as Figure 1 and Figure 3 As shown, the atomizer 1000 also includes a liquid storage cup 40, a mouthpiece 10 is disposed at one end of the liquid storage cup 40, and a liquid collection structure 30 is provided at the end of the liquid storage cup 40 near the mouthpiece 10. The liquid collection structure 30 includes a liquid collection tank, which may be filled with a liquid suction component 301 or not. Taking the liquid collection tank filled with a liquid suction component 301 as an example, the drainage outlet 105 guides the droplets flowing out of the guide channel 103 to the liquid suction component 301 in the liquid collection tank.

[0045] In some embodiments, an oil storage cotton 401 is provided inside the liquid storage cup 40, which is used to store the atomizing matrix.

[0046] In some embodiments, such as Figure 2 As shown, the suction nozzle 10 includes a first cavity 111 and at least two second cavities 112; the first cavity 111 is located between the two second cavities 112, and the air guide channel 101 is disposed in the first cavity 111 and there is a gap between it and the first cavity 111; at least two second cavities 112 are connected to the liquid collection structure 30.

[0047] In some embodiments, a sealing element 50 is provided between the liquid collecting structure 30 and the liquid storage cup 40 (e.g., ...). Figure 3 As shown, the seal 50 is used to seal the gap between the nozzle 10 and the reservoir 40. This seal 50 can be made of soft materials such as plastic, rubber, or silicone.

[0048] The condensate droplets generated during the use of the atomizer 1000 can be directed along the guide channel 103 to the drain outlet 105. The drain outlet 105 guides the condensate droplets to the liquid suction component 301 in the liquid collection tank, thus completing the directional discharge of the condensate droplets. This improves the user experience and extends the service life of the atomizer 1000.

[0049] In some embodiments, such as Figure 4 As shown, the nozzle 10 includes a housing 107, which forms an air guide tube 108, a liquid storage chamber 109, and an air outlet 110. The liquid storage chamber 109 is used to store the atomizing matrix. The air guide tube 108 forms an air guide channel 101, with one end connected to the air outlet 110 and the other end connected to the atomizing assembly 20. The atomizing assembly 20 is provided with a heating element 201 and a liquid guide 202. The liquid guide 202 is used to transfer the liquid from the liquid storage chamber 109 to the heating element 201. The liquid guide 202 can also serve as a liquid suction component 301. The flow channel 103 connects to the liquid guide 202. In this embodiment, the flow channel 103 directly guides the condensed droplets to the liquid guide 202, and the condensed droplets are directly heated and atomized by the heating element 201.

[0050] In some embodiments, the atomizer 1000 further includes a reservoir 40 (e.g., Figure 3 As shown, the liquid storage cup 40 forms a liquid storage cavity 109; the suction nozzle 10 is disposed at one end of the liquid storage cup 40; the atomizing assembly 20 is provided with a heating element 201 and a liquid guiding component 202. The liquid guiding component 202 is used to transfer the liquid in the liquid storage cavity 109 to the heating element 201, and the liquid guiding component 202 also serves as a liquid suction component 301. The flow channel 103 connects to the liquid guiding component 202. In this embodiment, the flow channel 103 directly guides the condensed droplets to the liquid guiding component 202, and the condensed droplets are directly heated and atomized by the heating element 201.

[0051] In some embodiments, the outer peripheral surface of the liquid guide 202 may communicate with the liquid storage cavity 109, and the inner peripheral surface of the liquid guide 202 may be in contact with the heating element 201. In this way, the liquid guide 202 can transfer the atomized matrix in the liquid storage cavity 109 to the heating element 201, and the heating element 201 can perform atomization processing.

[0052] It should be noted that the liquid guiding component 202 can be made of porous materials such as porous glass substrate, porous metal substrate, porous silicon carbide, porous silicon nitride or porous mullite.

[0053] It should be noted that the heating element 201 can be a structure such as a heating wire, a heating plate, or a heating mesh.

[0054] It should be noted that the liquid guiding component 202 can be made of absorbent materials such as cotton pads or sponges, allowing the atomizing matrix to pass through.

[0055] This application solves the problem of condensate droplets accumulating in the airflow channel of the atomizer nozzle by setting a micro-surface texture on the inner surface of the airflow channel. The micro-surface texture forms a flow channel and intercepts condensate droplets through the "pinning effect". Under the action of the airflow of the user's normal inhalation, the condensate droplets are directionally discharged through the flow channel, thereby solving the problem of condensate droplets accumulating in the airflow channel of the nozzle.

[0056] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
