[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, some embodiments of the utility model provide a nozzle, which is mainly used in an aerosol generating device to enable users to change different smoking flavors according to their own preferences during use, thereby improving the user's usage experience and meeting the different needs of users during the smoking process.

[0035] The nozzle includes a nozzle body 100 and a carrier 200 .

[0036] The nozzle body 100 defines an exhaust channel 110 , a first guide channel 120 , and an air inlet channel 130 that are connected in sequence, and an inner wall of the nozzle body 100 defines a first step 140 and a limiting ring 150 that are spaced apart from each other.

[0037] It should be noted that the axes of the exhaust channel 110 , the first guide channel 120 and the air inlet channel 130 coincide with each other to ensure the smoothness of the gas flowing through the nozzle body 100 and to increase the flow rate of the gas flowing through the nozzle body 100 per unit time.

[0038] The first step 140 is located between the first guide channel 120 and the exhaust channel 110 , and the limiting ring 150 is arranged between the first guide channel 120 and the intake channel 130 .

[0039] In addition, the inner diameter of the limiting ring 150 is smaller than the outer diameter of the carrier 200 , so that the limiting ring 150 can provide a limiting effect on the carrier 200 .

[0040] Specifically, the carrier 200 is arranged in the first guide channel 120, and the outer wall of the carrier 200 abuts against the inner wall of the first guide channel 120 to increase the friction between the carrier 200 and the inner wall of the first guide channel 120 to prevent the carrier 200 from sliding in the first guide channel 120, thereby improving the stability of the carrier 200 in the first guide channel 120.

[0041] In this embodiment, along the axial direction of the nozzle body 100, one end of the carrier 200 abuts against the first step 140, and the other end of the carrier 200 abuts against the limiting ring 150, so as to limit the carrier 200 through the first step 140 and the limiting ring 150, so as to further improve the stability of the carrier 200 in the first guide channel 120.

[0042] The carrier 200 defines a second guide channel 210 communicating with the exhaust channel 110 and the intake channel 130 .

[0043] In this embodiment, the axis of the second guide channel 210 , the axis of the exhaust channel 110 , the axis of the first guide channel 120 , and the axis of the intake channel 130 coincide with each other to improve the smoothness of gas flow in the nozzle body 100 .

[0044] In addition, it should be noted that the inner diameter of the exhaust channel 110 is larger than the inner diameter of the second guide channel 210 to ensure the smoothness of the gas flowing through the carrier 200 into the exhaust channel 110. It is understandable that when the gas enters the exhaust channel 110 through the second guide channel 210, the flow rate of the gas decreases due to the increase in the inner diameter, which can improve the taste of the user during the smoking process.

[0045] Furthermore, a plurality of guide holes are provided on the surface of the carrier 200 , and the plurality of guide holes are distributed at intervals on the surface of the carrier 200 .

[0046] The guide hole is connected to the second guide channel 210 , and the carrier 200 is used to carry a filler in a liquid, paste, solid or powdered form.

[0047] It should be noted that the filler includes but is not limited to at least one of ointments, spices, flavors, flavoring agents, health products and medical formulas, etc. In addition, the filler can be any one of solid spices, emulsion flavors and paste flavoring agents.

[0048] In this embodiment, the surface of the carrier 200 is provided with flow-guiding holes in a honeycomb structure to increase the number of the flow-guiding holes.

[0049] Specifically, in this embodiment, the guide holes are used to carry liquid, paste or powder fillers, so that when the user smokes, the gas flows through the second guide channel 210, and the aroma of the filler carried in the guide holes can be brought into the second guide channel 210, and the gas in the second guide channel 210 enters the user's mouth through the exhaust channel 110, which can not only improve the user's taste when smoking cigarettes, but also increase the fragrance, thereby enhancing the user's experience.

[0050] In addition, since the carrier 200 is detachably connected to the nozzle body 100, the user can also add the flavors, medicines and health products of his or her needs to the guide holes of the carrier 200 according to his or her own situation, so that when the user smokes, the smoke can carry the smell of the flavors, medicines or health products in the carrier 200 into the user's mouth when passing through the second guide channel 210, and the user's smoking taste can be improved by the smoke carrying the flavors. The smoke carrying the medicines or health products can not only have a health or therapeutic effect on the user, but also reduce the harm of smoking.

[0051] It not only improves the versatility of the nozzle and enhances the user experience, but also facilitates the removal of the carrier 200 from the nozzle body 100 for easy cleaning or replacement, thereby improving the utilization rate of the carrier 200 and reducing the user's maintenance and replacement costs.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the nozzle body 100 has a nozzle head 160 .

[0053] Specifically, along the axial direction of the nozzle body 100, the outer diameter of the suction head portion 160 first decreases and then increases from the side close to the carrier 200 to the side away from the carrier 200, so as to form a flat structure recessed in the axial direction of the nozzle body 100 on the outer periphery of the suction head portion 160. The flat structure conforms to human body mechanics, so that when the user holds the suction head portion 160 with his mouth, the outer shape of the suction head portion 160 can completely fit the shape of the human mouth, thereby enhancing the user experience.

[0054] The suction head 160 is any one of a silicone head, a plastic head, a metal head, a ceramic head, a wooden head or a fiber head.

[0055] Preferably, in this embodiment, the suction head 160 is a food-grade silicone head. It should be noted that food-grade silicone is an inorganic polymer colloidal material formed by the polycondensation of silicate, which is non-toxic and tasteless, has stable chemical properties, and does not react with any acid, alkali or salt except caustic soda and hydrofluoric acid under normal conditions. Food-grade silicone has the advantages of softness, high tear resistance, high insulation, wear resistance, high temperature resistance, flame retardancy, aging resistance, environmental protection, tensile strength, and stable performance.

[0056] The suction head 160 is made of food-grade silicone to ensure the safety of the user during use.

[0057] like Figure 3 and Figure 5 As shown, in some embodiments of the present invention, at least one mounting hole 220 is defined at one end of the carrier 200 close to the air inlet channel 130 , and the mounting hole 220 is communicated with the second guide channel 210 .

[0058] It is understandable that the number of the mounting holes 220 can be one, two, or any number above two, and can be set according to actual conditions.

[0059] It should be noted that in this embodiment, the aperture of the mounting hole 220 is larger than the aperture of the second guide channel 210 , and the axis of the mounting hole 220 coincides with the axis of the second guide channel 210 to ensure smooth flow of gas in the mounting hole 220 and the second guide channel 210 .

[0060] In this embodiment, a mounting hole 220 is provided at one end of the carrier 200 so that the mounting hole 220 can carry a cigarette butt, that is, the cigarette butt can be inserted into the mounting hole 220, and the cigarette butt abuts against the hole wall of the mounting hole 220, so that the hole wall of the mounting hole 220 can form a limiting effect on the cigarette butt, thereby improving the stability of the connection between the cigarette and the carrier 200.

[0061] like Figure 3 and Figure 5 As shown, in some embodiments of the present invention, there are multiple mounting holes 220 , and the apertures of the multiple mounting holes 220 gradually decrease from one end of the carrier 200 close to the air intake passage 130 to one end close to the exhaust passage 110 .

[0062] It is understandable that by providing multiple mounting holes 220, not only can the carrying capacity of the carrier 200 for the filler be improved, but also by providing multiple mounting holes 220 with different apertures, the user's smoking demand for cigarettes of different calibers can be improved, thereby improving the user's usage experience.

[0063] Preferably, multiple mounting holes 220 are evenly distributed on the periphery of the carrier 200, so that when the smoke flows through the second guide channel 210, the smell in the mounting holes 220 carrying the filler can be evenly carried in the smoke, thereby improving the uniformity of the distribution of the smell of the filler in the smoke and enhancing the user's smoking experience.

[0064] Specifically, in this embodiment, the multiple mounting holes 220 include at least a first mounting hole 221 and a second mounting hole 222, and the aperture of the first mounting hole 221 is larger than the aperture of the second mounting hole 222, so that cigarette butts of different sizes can be carried through the first mounting hole 221 and the second mounting hole 222 to meet the user's needs for smoking different cigarettes and enhance the user's experience.

[0065] In some embodiments of the present invention, the axis of the mounting hole 220, the axis of the second guide channel 210, the axis of the exhaust channel 110, the axis of the first guide channel 120 and the axis of the air inlet channel 130 coincide with each other to ensure the smoothness of the gas during the internal circulation of the nozzle body 100.

[0066] like Figure 5 As shown, in some embodiments of the present invention, the aperture of the air inlet channel 130 is greater than or equal to the aperture of the mounting hole 220 to ensure that cigarette butts of different diameters can pass through the air inlet channel 130 and connect with the hole wall of the mounting hole 220, thereby meeting the user's smoking needs for different cigarettes.

[0067] like Figure 3 and Figure 5 As shown, in some embodiments of the present invention, the side of the limiting ring 150 away from the carrier 200 is a conical surface 151, and the inner diameter of the conical surface 151 gradually decreases from the end away from the carrier 200 to the end close to the carrier 200.

[0068] It can be understood that by setting the side of the limiting ring 150 facing away from the carrier 200 as a conical surface 151, when the cigarette butt is inserted into the mounting hole 220, the conical surface 151 can provide a limiting and guiding effect on the cigarette butt, thereby improving the smoothness of the cigarette butt being inserted into the mounting hole 220.

[0069] In some embodiments of the present invention, the nozzle body 100 is made of silicone. It should be noted that silicone has excellent elasticity and flexibility, and can be used with a variety of different materials, such as different additives, different pigments, etc., to enhance the plasticity and applicability of silicone, and has a good hand feel, a comfortable touch, and great flexibility, so as to enhance the comfort of the user during the smoking process.

[0070] In some embodiments of the present invention, the carrier 200 is any one of a ceramic tube, a glass tube, a metal tube, a fiber tube, a plastic tube and a wooden tube.

[0071] Preferably, in this embodiment, the carrier 200 is a porous ceramic tube.

[0072] It should be noted that ceramic is a neutral material with stable chemical properties and good acid resistance. It can resist corrosion from various inorganic acids, organic acids and organic solvents. Its corrosion resistance is more than ten times that of stainless steel. It is also wear-resistant and high-temperature resistant, thereby improving the durability and service life of the carrier 200.

[0073] Some embodiments of the present invention further provide an aerosol generating device, comprising the nozzle described in any one of the above embodiments.

[0074] It should be noted that the aerosol generating device described in this embodiment has the structure of the nozzle described in any of the above embodiments, and has the beneficial effects produced by the nozzle described in any of the above embodiments, which will not be described one by one here.

[0075] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0076] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0077] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
