[0034] In order to illustrate the technical solution of the present invention, a detailed description is given below in conjunction with specific drawings and embodiments.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 , an embodiment of the present invention provides an atomizer, comprising:

[0036] The cigarette cartridge tube 2 has an oil storage chamber 21 in it, an oil injection hole 211 is provided at the bottom of the oil storage chamber 21, and a first protrusion 29 is provided on the inner wall of the cigarette cartridge tube 2 extending inward;

[0037] The base 6 is sleeved in the cigarette cartridge tube 2. The cigarette cartridge tube 2 and the base 6 enclose an atomization chamber 66. The outer wall of the base 6 is provided with a second protrusion 64 extending outward. The first protrusion 29 and the second protrusion 64 are spaced apart and parallel to the assembly direction of the cigarette cartridge tube 2 and the base 6.

[0038] A sealing ring 7, sealingly disposed between the first protrusion 29 and the second protrusion 64; and

[0039] The heating component 4 is disposed in the atomizing chamber 66 and is sealed and connected below the oil filling hole 211 .

[0040] In the atomizer of the embodiment of the present invention, a first protrusion 29 is extended on the inner wall of the cigarette cartridge tube 2 in a direction close to the base 6, and a second protrusion 64 is extended on the outer wall of the base 6 in a direction close to the cigarette cartridge tube 2. The first protrusion 29 and the second protrusion 64 are spaced apart in parallel to the assembly direction of the cigarette cartridge tube 2 and the base 6. A sealing ring 7 is arranged between the first protrusion 29 and the second protrusion 64, so that the end face of one end of the sealing ring 7 is sealed and connected to a surface of the first protrusion 29 close to the second protrusion 64, and the end face of the other end of the sealing ring 7 is sealed and connected to a surface of the second protrusion 64 close to the first protrusion 29, so that a planar sealing structure perpendicular to the assembly direction of the cigarette cartridge tube 2 and the base 6 is formed between the cigarette cartridge tube 2 and the base 6, and the side wall of the cigarette cartridge tube 2 will not be subjected to the outward thrust of the interference, which effectively avoids the situation where the diameter of the cigarette cartridge tube 2 becomes larger and causes oil leakage.

[0041] Specifically, in a conventional atomizer, the heating component is sealed and connected to the opening at the lower end of the oil storage chamber, and the sealing area between the heating component and the opening at the lower end of the oil storage chamber is relatively large, making it difficult to ensure the sealing strength between the heating component and the opening at the lower end of the oil storage chamber. In the atomizer of the embodiment of the present invention, the cross-sectional area of ​​the oil injection hole 211 is smaller than the cross-sectional area of ​​the oil storage chamber 21, and the heating component 4 is sealed and connected to the oil injection hole 211. Compared with the conventional atomizer structure, the sealing area between the heating component 4 and the oil injection hole 211 of the oil storage chamber 21 of the embodiment of the present invention is smaller, which can better ensure the sealing strength between the heating component 4 and the oil injection hole 211 of the oil storage chamber 21, and based on this, oil leakage can be effectively prevented.

[0042] Specifically, in one embodiment of the present invention, the end surface of one end of the sealing ring 7 is sealed to a surface of the first protrusion 29 close to the second protrusion 64, and the end surface of the other end of the sealing ring 7 is sealed to a surface of the second protrusion 64 close to the first protrusion 29. Figure 5As shown, the end face of the sealing ring 7 facing away from the second protrusion 64 is interference fit with the side of the first protrusion 29 close to the second protrusion 64, and the end face of the sealing ring 7 facing away from the first protrusion 29 is interference fit with the side of the second protrusion 64 close to the first protrusion 29, so that a planar sealing structure perpendicular to the assembly direction of the cigarette bomb tube 2 and the base 6 is formed between the cigarette bomb tube 2 and the base 6, and the side wall of the cigarette bomb tube 2 will not be subjected to the outward thrust due to the interference, which effectively prevents the situation where the diameter of the cigarette bomb tube 2 becomes larger and causes oil leakage.

[0043] Specifically, in one embodiment of the present invention, the base 6 is detachably sleeved in one end of the cartridge tube 2. Optionally, the cartridge tube 2 is snap-connected with the base 6. Of course, according to the actual situation, the cartridge tube 2 and the base 6 can be detachably connected by other connection methods, and the present invention is not limited here.

[0044] Furthermore, combined with Figure 2 , Figure 3 as well as Figure 5 A first buckle 62 is provided on the outer wall of the base 6, and the first buckle 62 is located on the side of the first protrusion 29 away from the second protrusion 64. A first buckle groove 28 is provided on the inner wall of the cigarette cartridge tube 2 corresponding to the first buckle 62, and the first buckle 62 is buckled in the first buckle groove 28, thereby realizing a detachable connection between the base 6 and the cigarette cartridge tube 2; or,

[0045] A first buckle 62 is provided on the inner wall of the cartridge tube 2, and the first buckle 62 is located on the side of the first protrusion 29 away from the second protrusion 64. A first buckle groove 28 is provided on the outer wall of the base 6 corresponding to the first buckle 62, and the first buckle 62 is buckled in the first buckle groove 28, thereby realizing a detachable connection between the base 6 and the cartridge tube 2. It can be understood that, according to the actual choice, the first buckle 62 can also be set on the inner wall of the cartridge tube 2, and correspondingly, the first buckle groove 28 is set on the outer wall of the base 6, and the present invention is not limited here.

[0046] Specifically, in one embodiment of the present invention, in combination Figure 3 and Figure 5 A groove 63 is provided on the outer wall of the base 6 corresponding to the sealing ring 7, and the sealing ring 7 is embedded in the groove 63. The sealing ring 7 extends toward the inner wall of the cigarette cartridge tube 2 to form a sealing step 71. The end face of the sealing step 71 away from the second protrusion 64 is interference fit on the side of the first protrusion 29 close to the second protrusion 64, and the end face of the sealing ring 7 away from the first protrusion 29 is interference fit on the side of the second protrusion 64 close to the first protrusion 29, so that a planar sealing structure perpendicular to the assembly direction of the cigarette cartridge tube 2 and the base 6 is formed between the cigarette cartridge tube 2 and the base 6, and the side wall of the cigarette cartridge tube 2 will not be subjected to the outward thrust of the interference, which effectively avoids the situation where the diameter of the cigarette cartridge tube 2 becomes larger and causes oil leakage.

[0047] Specifically, in order to further increase the sealing strength between the base 6 and the cigarette cartridge tube 2, a planar sealing method parallel to the assembly direction of the cigarette cartridge tube 2 and the base 6 can be appropriately increased, such as a first protrusion 29 close to the side of the base 6 is interference fit with the side of the sealing ring 7 close to the cigarette cartridge tube 2 to form a sealed state. In this embodiment, the sealing strength between the base 6 and the cigarette cartridge tube 2 is mainly achieved by a planar sealing method perpendicular to the assembly direction of the cigarette cartridge tube 2 and the base 6, supplemented by a planar sealing method parallel to the assembly direction of the cigarette cartridge tube 2 and the base 6, so as to avoid the side wall of the cigarette cartridge tube 2 being subjected to the outward thrust of the interference and causing dimensional deformation.

[0048] Specifically, in one embodiment of the present invention, in combination Figure 2 , Figure 3 and Figure 6 , a baffle 23 is provided on the inner edge of the cartridge tube 2, and the baffle 23 is used to divide the internal space of the cartridge tube 2 into an oil storage chamber 21 and a first smoke outlet channel 22 arranged in parallel, and the atomization chamber 66 is connected to the first smoke outlet channel 22. The cartridge tube 2 is columnar, and a baffle 23 is provided inside the cartridge tube 2 along its length direction, and the baffle 23 divides the internal space of the cartridge tube 2 into an oil storage chamber 21 and a first smoke outlet channel 22 that are isolated from each other. It can be understood that, according to the actual situation, the shape of the cartridge tube 2 can be appropriately modified, and the baffle 23 can also be arranged along the width direction of the cartridge tube 2 or other directions, and the present invention is not limited here.

[0049] It should be emphasized that in traditional atomizers, the smoke outlet channel is set in the middle of the oil storage chamber. Due to space limitations, the gap between the inner wall of the oil storage chamber and the outer wall of the smoke outlet channel is short. When injecting smoke oil, the smoke oil must flow through this small gap and fill the entire oil storage chamber. If the oil injection speed is too fast, the smoke oil will quickly fill one side of the oil storage chamber, causing the smoke oil to flow into the inner hole of the middle smoke outlet channel, resulting in smoke oil waste and product scrapping. Therefore, the smoke oil can only be injected at a slower speed, which will undoubtedly reduce the efficiency of injecting smoke oil. In the atomizer of the embodiment of the present invention, a baffle 23 is provided in the smoke cartridge tube 2 to divide the internal space of the smoke cartridge tube 2 into an oil storage chamber 21 and a first smoke outlet channel 22 which are isolated from each other, so that the oil storage chamber 21 and the first smoke outlet channel 22 are respectively located on opposite sides of the internal space of the smoke cartridge tube 2. When smoke oil is injected into the oil storage chamber 21 from the oil filling hole 211, the smoke oil can directly fill the entire oil storage chamber 21 without flowing through a narrow gap (the gap between the inner wall of the traditional oil storage chamber 21 and the outer wall of the smoke outlet channel) to fill the entire oil storage chamber 21. Compared with the traditional atomizer, the atomizer of the embodiment of the present invention has a higher efficiency in injecting smoke oil, and can prevent the smoke oil from flowing into the first smoke outlet channel 22 when injecting smoke oil into the oil storage chamber 21.

[0050] Specifically, combined Figure 3and Figure 6 In one embodiment of the present invention, the end of the baffle 23 close to the base 6 extends in a direction away from the first smoke outlet channel 22 to form a partition 24, the side wall of the cartridge tube 2, the baffle 23 and the partition 24 enclose an oil storage chamber 21, the baffle 23 and the side wall of the cartridge tube 2 enclose the first smoke outlet channel 22, and the oil injection hole 211 is provided on the partition 24, so that the oil storage chamber 21 and the first smoke outlet channel 22 are in a two-side isolation structure, which effectively improves the efficiency of injecting smoke oil, improves or eliminates the phenomenon that the smoke oil flows into the first smoke outlet channel 22 when the oil storage chamber 21 is injected with smoke oil. In this embodiment, the partition 24, the inner wall of the end of the cartridge tube 2 away from the nozzle assembly 1 and the base 6 enclose an atomization chamber 66.

[0051] It is understandable that, according to the actual situation, the baffle 23 and the partition plate 24 can be structures of other shapes, as long as it can ensure that the internal space of the cigarette cartridge tube 2 can be divided into the oil storage chamber 21 and the first smoke outlet channel 22 of the two side structures, and the atomization chamber 66 is connected to the oil storage chamber 21 and the first smoke outlet channel 22. The present invention is not limited here.

[0052] Specifically, in one embodiment of the present invention, in combination Figure 3 and Figure 6 A first sealed tube wall 25 is provided on one side of the partition plate 24 away from the oil storage chamber 21 and on both sides of the corresponding oil filling hole 211. The first sealed tube wall 25 and the side wall of the cigarette bomb tube 2 are enclosed to form a sealed chamber 26. The heating component 4 is sealed and connected to the sealed chamber 26, so that the smoke oil flowing out of the oil filling hole 211 must be atomized by the heating component 4 before entering the atomization chamber 66, thereby preventing the smoke oil from directly flowing into the atomization chamber 66 and being inhaled by the user.

[0053] Specifically, in one embodiment of the present invention, in combination Figure 2 , Figure 3 , Figure 6 and Figure 7 The atomizer further comprises a sealing cover 3 which is inserted in the sealing cavity 26 by interference fit, and the sealing cover 3 has a receiving groove 31 which opens toward the base 6, and an oil inlet hole 311 which exposes the oil filling hole 211 is provided at the bottom of the receiving groove 31 by interference fit, so that the smoke oil flowing out of the oil storage cavity 21 is saturatedly absorbed and stored by the heating component 4, so that the heating component 4 can atomize the smoke oil when the power is turned on, and prevent the smoke oil from leaking and flowing directly into the atomization cavity 66. In this embodiment, the oil inlet hole 311 completely exposes the oil filling hole 211, that is, the cross-sectional area of ​​the oil inlet hole 311 is larger than the cross-sectional area of ​​the oil filling hole 211, so that the smoke oil flowing out of the oil filling hole 211 can smoothly reach the heating component 4.

[0054] Optionally, combined Figure 3 and Figure 7The outer wall of the sealing cover 3 extends outward to form at least one circle of first sealing bosses 32, and the first sealing bosses 32 are interference-fitted with the inner wall of the sealing cavity 26, thereby achieving a sealed connection between the sealing cover 3 and the inner wall of the sealing cavity 26. In this embodiment, the material of the sealing cover 3 is an elastic material, such as rubber or silicone.

[0055] Optionally, combined Figure 3 and Figure 7 The inner wall of the accommodating groove 31 extends inward to form at least one circle of second sealing bosses 33 , and the heating component 4 is interference fit with the second sealing bosses 33 , thereby achieving a sealed connection between the heating component 4 and the inner wall of the accommodating groove 31 .

[0056] It is worth mentioning that when the volume of the sealing cover 3 made of silicone material is large, it is easy to deform and not conducive to sealing, which is easy to cause oil leakage. In the embodiment of the present invention, the cross-sectional area of ​​the oil injection hole 211 is smaller than the cross-sectional area of ​​the oil storage cavity 21 to reduce the sealing area between the oil injection hole 211 and the heating component 4, thereby reducing the volume of the sealing cover 3, thereby reducing the probability of deformation of the sealing cover 3, improving the sealing strength, and effectively avoiding the occurrence of oil leakage.

[0057] Specifically, in one embodiment of the present invention, in combination Figure 3 , Figure 7 and Figure 8 The heating component 4 includes an oil-conducting base 41 disposed below the oil injection hole 211, and a resistance heating element 42 embedded in the surface of the oil-conducting base 41 on a side away from the oil injection hole 211. The oil-conducting base 41 is embedded in the receiving groove 31, and the outer wall of the oil-conducting base 41 and the inner wall of the receiving groove 31 (the second sealing boss 33) are interference-fitted, so that the heating component 4 and the inner wall of the receiving groove 31 are sealed and connected, preventing the smoke oil from leaking from between the oil-conducting base 41 and the inner wall of the receiving groove 31.

[0058] In the atomizer of the embodiment of the present invention, the smoke oil in the oil storage chamber 21 passes through the oil filling hole 211 and the oil inlet hole 311 in sequence and reaches the surface of the oil guide matrix 41 close to the suction nozzle assembly 1. The oil guide matrix 41 has a porous structure and is provided with a large number of interconnected micropores. The micropores on the surface of the oil guide matrix 41 close to the suction nozzle assembly 1 absorb the smoke oil and guide it to the surface of the oil guide matrix 41 away from the suction nozzle assembly 1. The resistance heating element 42 generates heat to atomize the smoke oil when the current is turned on.

[0059] Specifically, in one embodiment of the present invention, the oil-conducting matrix 41 is made of a porous ceramic material, which specifically includes a combination of raw materials such as aggregate, adhesive, and pore-forming agent. The porous ceramic material and the resistive heating element 42 are placed in a mold together for molding, and then sintered and solidified to form an integrally molded component. In this embodiment, the oil-conducting matrix 41 has a large number of interconnected microporous structures.

[0060] Specifically, in one embodiment of the present invention, the porosity of the oil-conducting matrix 41 reaches 40%-70% to ensure that the oil intake of the oil-conducting matrix 41 is balanced with the heating energy of the resistive heating element 42, thereby avoiding the occurrence of scorching, making the smoke more delicate, and greatly improving the taste of the smoke oil after being atomized.

[0061] Specifically, in one embodiment of the present invention, in combination Figure 2 , Figure 3 and Fig. 9 The base 6 is provided with an air inlet 61, which is connected to the atomizing chamber 66. The atomizer further includes an oil absorbing carrier 5 disposed in the atomizing chamber 66. The oil absorbing carrier 5 is disposed on the base 6, and a first avoidance hole 51 for avoiding the air inlet 61 is provided on the oil absorbing carrier 5. In this embodiment, the surface of the oil guide base 41 away from the nozzle assembly 1 is flush with the surface of the resistance heating element 42, and the air entering from the air inlet 61 can completely and evenly impact the exposed surface of the resistance heating element 42, taking away the smoke atomized by the resistance heating element 42.

[0062] Specifically, in one embodiment of the present invention, the cross-sectional area of ​​the oil filling hole 211 is greater than or equal to 50% of the cross-sectional area of ​​one end of the oil guide base 41 close to the oil filling hole 211, thereby ensuring the oil intake of the oil guide base 41. Compared with the traditional atomizer, the oil guide base 41 of the embodiment of the present invention does not need to be wrapped or attached to the oil guide cotton. On the one hand, it can prevent the oil guide cotton from being burned and producing a burnt smell. On the other hand, it prevents the oil guide cotton from filtering and weakening the taste of the smoke oil, restores the taste of the smoke oil, and improves the fineness of the smoke.

[0063] Specifically, in one embodiment of the present invention, in combination Figure 2 , Figure 3 , Figure 7 and Fig. 9 , the base 6 is detachably connected to the sealing cover 3. Optionally, a hook 65 is provided on the base 6 extending toward the sealing cover 3, and a corresponding slot 34 cooperating with the hook 65 is provided on the inner wall of the receiving groove 31 of the sealing cover 3, and the hook 65 is buckled on the slot 34, thereby realizing the detachable connection between the base 6 and the sealing cover 3. It can be understood that, according to the actual situation, other connection methods can be used to realize the detachable connection between the base 6 and the sealing cover 3, and the present invention is not limited here.

[0064] Furthermore, combined with Figures 7 to 9 One end of the oil-conducting base 41 away from the base 6 extends toward opposite sides to form a limiting step 411, and the end surface of the hook 65 close to the sealing cover 3 is in close contact with the end surface of the limiting step 411 close to the base 6, that is, the end surface of the hook 65 close to the sealing cover 3 abuts against the end surface of the limiting step 411 close to the base 6. In this embodiment, when the hook 65 of the base 6 is buckled on the slot 34 of the sealing cover 3, a compression assembly is formed between the hook 65 of the base 6 and the sealing cover 3 in a direction parallel to the assembly direction of the cigarette bomb tube 2 and the base 6, so that a side of the oil-conducting base 41 close to the oil filling hole 211 is tightly fitted on the bottom surface of the accommodating groove 31, that is, a side of the oil-conducting base 41 close to the oil filling hole 211 is sealed and connected to the bottom surface of the accommodating groove 31. In this embodiment, the cross-sectional area of ​​the oil inlet hole 311 is smaller than the cross-sectional area of ​​one end of the oil guide base 41 close to the oil injection hole 211 , so that one side of the oil guide base 41 close to the oil injection hole 211 can fit tightly against the bottom surface of the accommodating groove 31 .

[0065] Specifically, in one embodiment of the present invention, in combination Figure 2 , Figure 3 and Figure 7 The oil absorbing carrier 5 is spaced apart from the heating element 4 to prevent the oil absorbing carrier 5 from being burned. More specifically, a limiting column 35 is provided on the sealing cover 3 in the direction toward the base 6, and the end surface of the limiting column 35 close to the base 6 abuts against the oil absorbing carrier 5, thereby preventing the oil absorbing carrier 5 from moving toward the heating element 4 and being burned by the heat generated by the resistance heating element 42 when it is working.

[0066] Specifically, in one embodiment of the present invention, in combination Figure 2 and Figure 3 The atomizer further includes a conductive electrode 8 that penetrates the base 6. One end of the conductive electrode 8 extends into the atomizing chamber 66 and abuts against the resistance heating element 42, thereby supplying power to the resistance heating element 42. Compared with the traditional atomizer, the resistance heating element 42 of the embodiment of the present invention does not need to be provided with a conductive pin. Therefore, in the manufacturing process, it is not necessary to additionally mortise / weld the conductive pin on the resistance heating element 42, so that the quality control consistency of the product is good and the production efficiency is high. In this embodiment, a second avoidance hole 52 for avoiding the conductive electrode 8 is opened on the oil absorption base.

[0067] Specifically, in one embodiment of the present invention, in combination Figure 2 and Figure 3 The atomizer also includes an adsorption magnet 9 penetrated on the base 6, and the adsorption magnet 9 is used to magnetically connect the base 6 with the power supply body. When the base 6 is magnetically connected with the power supply body, the electrode of the power supply body abuts against the conductive electrode 8 and is electrically connected, thereby connecting the current to the resistive heating element 42.

[0068] Specifically, in one embodiment of the present invention, in combination Figures 1 to 3 The atomizer further includes a nozzle assembly 1 disposed at one end of the cartridge tube 2 away from the base 6. The nozzle assembly 1 is sealedly connected to the oil storage chamber 21 and communicated with the first smoke outlet channel 22, so as to facilitate the user to smoke. In this embodiment, the oil suction carrier 5 is disposed in the atomization chamber 66 and is located below the heating component 4 and the first smoke outlet channel 22.

[0069] In the atomizer of the embodiment of the present invention, by arranging the oil absorption carrier 5 below the heating component 4 and the first smoke outlet channel 22, when the atomizer is working, the smoke oil in the oil storage chamber 21 flows to the heating component 4 in the atomizing chamber 66 through the oil injection hole 211, and the heating component 4 atomizes the smoke oil to form smoke, and the smoke moves from the atomizing chamber 66 to the first smoke outlet channel 22, and finally flows out from the suction nozzle component 1. In the process of the heating component 4 atomizing the smoke oil, if the heating component 4 does not have time to atomize all the smoke oil flowing out of the oil injection hole 211, a small amount of smoke oil will drip from the heating component 4 and be absorbed and stored by the oil absorption carrier 5; and when the smoke moves from the atomizing chamber 66 to the first smoke outlet channel 22, a small amount of smoke will condense and reflux, forming condensate / smoke oil dripping and being absorbed and stored by the oil absorption carrier 5. Based on this, the oil absorption phenomenon can be improved or eliminated, greatly improving the user experience.

[0070] Specifically, in one embodiment of the present invention, in combination Figures 1 to 3 The nozzle assembly 1 includes a nozzle cover 11 connected to one end of the cigarette cartridge tube 2 away from the base 6, and a sealing seat 12 arranged between the nozzle cover 11 and the cigarette cartridge tube 2. The nozzle cover 11 is communicated with the first smoke outlet channel 22, and the sealing seat 12 is sealed and connected to the top of the oil storage chamber 21, thereby sealing the oil storage chamber 21 to prevent oil leakage from the open end of the oil storage chamber 21.

[0071] Further, in one embodiment of the present invention, in combination Figures 1 to 3 The sealing seat 12 is provided with a third sealing boss 121 at the opening end corresponding to the oil storage cavity 21. The third sealing boss 121 is plugged into the opening end of the oil storage cavity 21, and the side wall of the third sealing boss 121 is interference fit with the inner wall of the oil storage cavity 21, so that the opening end of the oil storage cavity 21 is sealed to avoid oil leakage. In this embodiment, in order to better achieve a sealed connection, the sealing seat 12 can be made of an elastic material, for example, rubber or silicone.

[0072] Specifically, in one embodiment of the present invention, in combination Figures 1 to 3An air outlet 111 is provided at one end of the nozzle cover 11 away from the cigarette bomb tube 2, and a second smoke outlet channel 122 is provided in the sealing seat 12. One end of the second smoke outlet channel 122 is coaxially fitted and connected with an end of the first smoke outlet channel 22 close to the nozzle assembly 1, and an end of the second smoke outlet channel 122 away from the first smoke outlet channel 22 is connected with the air outlet 111, thereby connecting the nozzle assembly 1 with the first smoke outlet channel 22.

[0073] It should be noted that, in the atomizer of the embodiment of the present invention, the second smoke outlet channel 122 includes a first smoke outlet segment 1221 coaxially connected to the first smoke outlet channel 22 at one end, a second smoke outlet segment 1222 vertically connected to the other end of the first smoke outlet segment 1221 at one end, and a third smoke outlet segment 1223 vertically connected to the second smoke outlet segment 1222 at one end, and the other end of the third smoke outlet segment 1223 is connected to the air outlet 111. In the actual production process, in order to facilitate demolding, the second smoke outlet segment 1222 will pass through the side of the sealing seat 12. Therefore, it is necessary to block the end of the second smoke outlet segment 1222 away from the first smoke outlet segment 1221 to prevent condensate from flowing out of this part, thereby effectively enhancing the air tightness of the second smoke outlet channel 122. Therefore, the atomizer of the embodiment of the present invention also includes a sealing plug 13 sealed and connected to the end of the second smoke outlet segment 1222 away from the first smoke outlet segment 1221.

[0074] Specifically, in one embodiment of the present invention, in combination Figures 1 to 3 The inner wall of the air outlet 111 extends toward the direction close to the sealing seat 12 to form a second sealed tube wall 112. The second sealed tube wall 112 is embedded in one end of the third smoke outlet segment 1223 away from the first smoke outlet segment 1221, and the second sealed tube wall 112 is interference fit with the inner wall of the third smoke outlet segment 1223, thereby realizing a sealed connection between the air outlet 111 and the third smoke outlet segment 1223.

[0075] Specifically, in one embodiment of the present invention, in combination Figures 1 to 3 The nozzle cover 11 is flat as a whole, and the width of the nozzle cover 11 is gradually widened toward the direction close to the cartridge tube 2, so as to adapt to the human mouth and facilitate the user to smoke. The nozzle cover 11 is hollow, and the sealing seat 12 is accommodated in the nozzle cover 11, and the outer wall of the sealing seat 12 is interference-fitted with the inner wall of the nozzle cover 11, thereby improving the airtightness between the nozzle assembly 1 and the cartridge tube 2.

[0076] Specifically, in one embodiment of the present invention, the nozzle cover 11 is detachably connected to the cigarette cartridge tube 2, so that the user can disassemble and maintain it by himself.

[0077] Optionally, combined Figures 1 to 3A second buckle groove 113 may be provided on the inner wall of the mouthpiece cover 11, and a second buckle 27 cooperating with the second buckle groove 113 may be provided on the outer wall of the cigarette cartridge tube 2, and the second buckle 27 is buckled in the second buckle groove 113, thereby realizing a detachable connection between the mouthpiece cover 11 and the cigarette cartridge tube 2; or,

[0078] A second buckle groove 113 is provided on the outer wall of the cigarette cartridge tube 2, and a second buckle 27 cooperating with the second buckle groove 113 is provided on the inner wall of the suction nozzle cover 11, and the second buckle 27 is buckled in the second buckle groove 113, thereby realizing a detachable connection between the suction nozzle cover 11 and the cigarette cartridge tube 2. In this embodiment, the cigarette cartridge tube 2 is buckled into the suction nozzle cover 11, and a compression assembly parallel to the assembly direction of the cigarette cartridge tube 2 and the suction nozzle cover 11 is formed between the cigarette cartridge tube 2 and the suction nozzle cover 11, so that the sealing seat 12 is clamped between the cigarette cartridge tube 2 and the suction nozzle cover 11, and at the same time, the second sealing boss 33 of the sealing seat 12 is plugged into the open end of the oil storage chamber 21 to prevent air leakage and condensate from flowing out. It can be understood that, according to the actual situation, other connection methods can be used to realize the detachable connection between the suction nozzle cover 11 and the cigarette cartridge tube 2, and the present invention is not limited here.

[0079] It is worth mentioning that after many tests, it was found that under the same suction force conditions, the cross-sectional area of ​​the smoke outlet channel is less than 5mm 2 When the condensate attached to the inner wall of the smoke outlet channel is sucked into the oral cavity under the influence of the rapid airflow, the cross-sectional area of ​​the smoke outlet channel is greater than or equal to 5mm. 2 The airflow changes smoothly, and the straight smoke outlet channel makes the airflow not buffered by resistance and is easy to absorb condensate / smoke oil. Based on this, the cross-sectional area of ​​the first smoke outlet channel 22 and the second smoke outlet channel 122 of the embodiment of the present invention is set to be greater than or equal to 5mm 2 , in order to further prevent the occurrence of oil absorption.

[0080] See also Figure 3 , Figure 4 and Figure 8The working process of the atomizer of the embodiment of the present invention is as follows: the smoke oil in the oil storage chamber 21 passes through the oil injection hole 211 and the oil inlet hole 311 in turn and reaches the surface of the oil guide base 41 close to the suction nozzle assembly 1. The micropores on the surface of the oil guide base 41 close to the suction nozzle assembly 1 absorb the smoke oil and guide it to the surface of the oil guide base 41 away from the suction nozzle assembly 1. The resistance heating element 42 generates heat to atomize the smoke oil when the current is turned on. When the user inhales through the air outlet 111 of the suction nozzle cover 11, the air enters the atomization chamber 66 from the air inlet 61 of the base 6 to form an airflow. The airflow impacts the surface of the oil guide base 41 away from the suction nozzle assembly 1 and takes away the atomized smoke. Then the airflow and the smoke pass through the first smoke outlet channel 22 and the second smoke outlet channel 122 in turn, and finally enter the user's mouth from the air outlet 111 of the suction nozzle cover 11.
