Description

Technical Field

[0001] The present invention relates to the technical field of steam atomizing smoking articles, and in particular to an atomizing device and an electronic cigarette. Background Art

[0002] The smoke outlet duct of the traditional atomizer device is set in the middle of the oil storage chamber, and this structure has the following two disadvantages: first, due to space limitations, the gap between the inner wall of the oil storage chamber and the outer wall of the smoke outlet duct 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 duct, 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 the smoke oil; second, when the smoke oil is atomized and passes through the smoke outlet duct, a small amount of smoke will condense and reflux, causing the user to absorb oil when using it next time, greatly affecting the user's experience. Summary of the invention

[0003] The object of the present invention is to provide an atomizing device, aiming to solve the technical problems of low efficiency of injecting smoke oil and the existence of oil absorption phenomenon in traditional atomizing devices.

[0004] The present invention is achieved in that an atomizing device comprises:

[0005] A smoke bomb tube, wherein a baffle is provided inside the smoke bomb tube, wherein the baffle is used to divide the internal space of the smoke bomb tube into an oil storage chamber and a first smoke outlet channel arranged in parallel, and an oil filling hole is provided at the bottom of the oil storage chamber;

[0006] A nozzle assembly is arranged at one end of the cigarette bomb tube, the nozzle assembly is sealed and connected to the oil storage cavity and communicated with the first smoke outlet channel;

[0007] A base, which is arranged at the other end of the cigarette cartridge tube and encloses the cigarette cartridge tube to form an atomization chamber, wherein the atomization chamber is communicated with the first smoke outlet channel;

[0008] A heating component is disposed in the atomizing chamber and below the oil filling hole; and

[0009] The oil absorption carrier is arranged in the atomization chamber and is located below the heating component and the first smoke outlet channel.

[0010] In one embodiment of the present invention, the oil absorption carrier and the heating component are spaced apart.

[0011] In one embodiment of the present invention, the atomization device further comprises a sealing cover arranged in the atomization chamber, the heating component is arranged in the sealing cover, an oil inlet hole connected to the oil filling hole is opened on the sealing cover, and the heating component is arranged below the oil inlet hole.

[0012] In one embodiment of the present invention, the sealing cover has a receiving groove with an opening toward the base, the oil inlet hole is arranged at the bottom of the receiving groove, and the heating component is embedded in the receiving groove.

[0013] In one embodiment of the present invention, a limiting column is provided on the sealing cover extending in a direction toward the base, and an end surface of the limiting column close to the base abuts against the oil absorbing carrier.

[0014] In one embodiment of the present invention, the cross-sectional area of ​​the first smoke outlet channel is greater than or equal to 5 mm 2 .

[0015] In one embodiment of the present invention, the heating component includes an oil-conducting base, and a resistive heating element embedded in a surface of a side of the oil-conducting base away from the oil filling hole.

[0016] In one embodiment of the present invention, the atomization device further comprises a conductive electrode penetrating the base, one end of the conductive electrode extends into the atomization chamber and abuts against the resistive heating element.

[0017] In one embodiment of the present invention, an air inlet is provided on the base, the air inlet is communicated with the atomization chamber, and a first avoidance hole for avoiding the air inlet is provided on the oil absorption carrier.

[0018] Another object of the present invention is to provide an electronic cigarette, comprising the atomization device as described above.

[0019] The atomizing device provided by the present invention has at least the following beneficial effects:

[0020] First, by arranging a baffle in the smoke cartridge tube, the internal space of the smoke cartridge tube is divided into an oil storage chamber and a first smoke outlet channel which are arranged in parallel, so that the oil storage chamber and the first smoke outlet channel are respectively located on opposite sides of the internal space of the smoke cartridge tube. When injecting smoke oil from the oil injection hole into the oil storage chamber, the smoke oil can directly fill the entire oil storage chamber without flowing through a narrow gap (the gap between the inner wall of the traditional oil storage chamber and the outer wall of the smoke outlet channel) and filling the entire oil storage chamber. Compared with the traditional atomization device, the atomization device of the present invention has a higher efficiency in injecting smoke oil, and can improve or prevent the phenomenon that the smoke oil flows into the first smoke outlet channel when injecting smoke oil into the oil storage chamber;

[0021] Second, by arranging an oil absorption carrier under the heating component and the first smoke outlet channel, when the user uses the atomization device, the smoke oil in the oil storage chamber flows to the heating component in the atomization chamber through the oil filling hole, the heating component atomizes the smoke oil to form smoke, the smoke moves from the atomization chamber to the first smoke outlet channel, and finally flows out from the suction nozzle component. In the process of the heating component atomizing the smoke oil, if the heating component does not have time to atomize all the smoke oil flowing out of the oil filling hole, a small amount of smoke oil will drip from the heating component and be absorbed and stored by the oil absorption carrier; and when the smoke moves from the atomization chamber to the first smoke outlet channel, a small amount of smoke will condense and reflux to form condensate / smoke oil dripping and be absorbed and stored by the oil absorption carrier. Based on this, the oil absorption phenomenon can be improved or eliminated, greatly improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to illustrate the technical solution of the present invention, a detailed description is given below in conjunction with specific drawings and embodiments.

[0037] See also Figures 1 to 3 , an embodiment of the present invention provides an atomization device, comprising:

[0038] A cigarette cartridge tube 2, wherein a baffle plate 23 is provided inside the cigarette cartridge tube 2, and the baffle plate 23 is used to divide the internal space of the cigarette cartridge tube 2 into an oil storage chamber 21 and a first smoke outlet channel 22 arranged in parallel, and an oil injection hole 211 is provided at the bottom of the oil storage chamber 21;

[0039] The nozzle assembly 1 is arranged at one end of the cigarette cartridge tube 2, and the nozzle assembly 1 is sealedly connected to the oil storage chamber 21 and communicated with the first smoke outlet channel 22;

[0040] The base 6 is disposed at the other end of the cigarette cartridge tube 2 and encloses the cigarette cartridge tube 2 to form an atomizing chamber 66, and the atomizing chamber 66 is communicated with the first smoke outlet channel 22;

[0041] The heating element 4 is disposed in the atomizing chamber 66 and below the oil filling hole 211; and

[0042] The oil absorption carrier 5 is arranged in the atomization chamber 66 and below the heating component 4 and the first smoke outlet channel 22. In this embodiment, the smoke bomb tube 2 is columnar, and a baffle 23 is arranged in the smoke bomb tube 2 along its length direction, and the baffle 23 divides the internal space of the smoke bomb tube 2 into an oil storage chamber 21 and a first smoke outlet channel 22 which are isolated from each other. It can be understood that the shape of the smoke bomb tube 2 can be appropriately modified according to the actual situation, and the baffle 23 can also be arranged along the width direction of the smoke bomb tube 2 or other directions, and the present invention is not limited here.

[0043] In the atomizer device of the embodiment of the present invention, a baffle 23 is arranged in the smoke bomb tube 2 to divide the internal space of the smoke bomb tube 2 into an oil storage chamber 21 and a first smoke outlet channel 22 arranged in parallel, 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 bomb tube 2. When the 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 and the outer wall of the smoke outlet channel) to fill the entire oil storage chamber 21. Compared with the traditional atomizer device, the atomizer device of the embodiment of the present invention has a higher efficiency in injecting smoke oil, and can prevent the phenomenon that the smoke oil flows into the first smoke outlet channel 22 when injecting smoke oil into the oil storage chamber 21.

[0044] In addition, by arranging the oil absorption carrier 5 below the heating component 4 and the first smoke outlet channel 22, when the atomization device is working, the smoke oil in the oil storage chamber 21 flows to the heating component 4 in the atomization 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 atomization 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 atomization 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.

[0045] Specifically, in one embodiment of the present invention, Figure 3 and Figure 6 As shown, the end of the baffle 23 away from the suction nozzle assembly 1 extends vertically in the direction away from the first smoke outlet channel 22 and forms a partition 24. The baffle 23 and the inner wall of the end of the cigarette cartridge tube 2 close to the suction nozzle assembly 1 enclose the first smoke outlet channel 22. The baffle 23, the partition 24 and the inner wall of the end of the cigarette cartridge tube 2 close to the suction nozzle assembly 1 enclose the oil storage chamber 21. The oil injection hole 211 is opened 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 and 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 cigarette cartridge tube 2 away from the suction nozzle assembly 1 and the base 6 enclose an atomization chamber 66.

[0046] 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.

[0047] Specifically, in one embodiment of the present invention, Figure 2 and Figure 3 As shown, 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 connected to 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.

[0048] Further, in one embodiment of the present invention, Figure 2 and Figure 3As shown, the sealing seat 12 is provided with a first sealing boss 121 at the opening end corresponding to the oil storage cavity 21, and the first sealing boss 121 is plugged into the opening end of the oil storage cavity 21, and the side wall of the first 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.

[0049] Specifically, in one embodiment of the present invention, Figure 3 As shown, an 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 with and connected to 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 to the air outlet 111, thereby connecting the nozzle assembly 1 with the first smoke outlet channel 22.

[0050] It should be noted that, in the atomization device 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 atomization device 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.

[0051] Specifically, in one embodiment of the present invention, Figure 3 As shown, the inner wall of the air outlet 111 extends toward the direction close to the sealing seat 12 to form a first sealed tube wall 112. The first sealed tube wall 112 is embedded in the end of the third smoke outlet segment 1223 away from the first smoke outlet segment 1221, and the first sealed tube wall 112 and the inner wall of the third smoke outlet segment 1223 are interference fit, thereby realizing a sealed connection between the air outlet 111 and the third smoke outlet segment 1223.

[0052] Specifically, in one embodiment of the present invention, Figure 2 and Figure 3As shown, the nozzle cover 11 is flat as a whole, and the width of the nozzle cover 11 is gradually widened towards 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 an inner hollow structure, and the sealing seat 12 is accommodated in the nozzle cover 11, and the outer wall of the sealing seat 12 is interference fit with the inner wall of the nozzle cover 11, thereby improving the airtightness between the nozzle assembly 1 and the cartridge tube 2.

[0053] Specifically, in one embodiment of the present invention, Figure 3 As shown, the mouthpiece cover 11 is detachably connected to the cigarette cartridge tube 2, so that the user can disassemble and maintain it by himself.

[0054] Optionally, a first buckle groove 113 may be provided on the inner wall of the mouthpiece cover 11, and a first buckle 27 cooperating with the first buckle groove 113 may be provided on the outer wall of the cigarette cartridge tube 2, and the first buckle 27 is buckled in the first buckle groove 113, thereby realizing a detachable connection between the mouthpiece cover 11 and the cigarette cartridge tube 2; or,

[0055] A first buckle groove 113 is provided on the outer wall of the cigarette cartridge tube 2, and a first buckle 27 cooperating with the first buckle groove 113 is provided on the inner wall of the suction nozzle cover 11, and the first buckle 27 is buckled in the first 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 is formed between the cigarette cartridge tube 2 and the suction nozzle cover 11 in a direction parallel to the assembly direction of 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 first sealing boss 121 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.

[0056] Specifically, in one embodiment of the present invention, Figure 2 and Figure 3 As shown, the atomization device also includes a sealing cover 3 disposed in the atomization chamber 66, a heating component 4 disposed in the sealing cover 3, the sealing cover 3 is tightly abutted against the partition plate 24, an oil inlet hole 311 connected to the oil injection hole 211 is provided on the sealing cover 3, the heating component 4 is disposed below the oil inlet hole 311 and tightly abutted against the sealing cover 3, and the cover of the heating component 4 is disposed at the oil inlet hole 311, so that the smoke oil flowing out of the oil storage chamber 21 is saturatedly absorbed and stored by the heating component 4, so that the heating component 4 can atomize the smoke oil when power is turned on, and avoid the smoke oil leakage directly flowing into the atomization chamber 66. In this embodiment, the oil inlet hole 311 completely exposes the oil injection hole 211, that is, the cross-sectional area of ​​the oil inlet hole 311 is larger than the cross-sectional area of ​​the oil injection hole 211, so that the smoke oil flowing out of the oil injection hole 211 can smoothly reach the heating component 4.

[0057] Specifically, in one embodiment of the present invention, Figure 3 and Figure 6 As shown, the partition plate 24 extends in a direction away from the suction nozzle assembly 1 to form a second sealing tube wall 25 arranged on opposite sides of the oil filling hole 211. The second sealing tube wall 25 and the inner wall of the cigarette bomb tube 2 are combined to form a sealing cavity 26. The sealing cover 3 is embedded in the sealing cavity 26. The outer wall of the sealing cover 3 and the inner wall of the sealing cavity 26 are interference fit, so that the sealing cover 3 and the inner wall of the sealing cavity 26 are sealed and connected, which can prevent the sealing cover 3 from deforming and causing the smoke oil to leak from the sealing cover 3.

[0058] Alternatively, if Figure 2 , Figure 6 and Figure 7 As shown, the outer wall of the sealing cover 3 extends outward to form at least one circle of second sealing bosses 32, and the second 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.

[0059] Specifically, in one embodiment of the present invention, Figure 2 , Figure 7 and Figure 8 As shown, the sealing cover 3 has a receiving groove 31 with an opening toward the base 6, an oil inlet hole 311 is provided at the bottom of the receiving groove 31, and the heating component 4 is embedded in the receiving groove 31. In this embodiment, the heating component 4 is tightly matched with the inner wall of the receiving groove 31, so that the heating component 4 and the inner wall of the receiving groove 31 are sealed and connected, which can prevent the leakage of smoke oil from between the heating component 4 and the inner wall of the receiving groove 31.

[0060] Alternatively, if Figure 2 , Figure 7 and Figure 8 As shown, the inner wall of the accommodating groove 31 extends inward to form at least one circle of third sealing bosses 33 , and the heating component 4 is interference fit with the third sealing bosses 33 , thereby achieving a sealed connection between the heating component 4 and the inner wall of the accommodating groove 31 .

[0061] Specifically, in one embodiment of the present invention, 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 easily leads to leakage of smoke oil. In order to solve the above problem, the cross-sectional area of ​​the oil injection hole 211 can be made smaller than the cross-sectional area of ​​the oil storage cavity 21, so as 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.

[0062] Specifically, in one embodiment of the present invention, Figure 2 , Figure 7 and Figure 8As shown, the heating component 4 includes an oil-conducting base 41 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 third 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.

[0063] In the atomization device 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.

[0064] 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.

[0065] 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.

[0066] Specifically, in one embodiment of the present invention, Figure 2 , Figure 3 and Figure 8 As shown, the base 6 is provided with an air inlet 61, which is connected to the atomizing chamber 66. The oil suction carrier 5 is provided on the base 6, and the oil suction carrier 5 is provided with a first avoidance hole 51 for avoiding the air inlet 61. 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.

[0067] Specifically, in one embodiment of the present invention, Figure 3As shown, 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 atomization device, 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.

[0068] Specifically, in one embodiment of the present invention, Figure 3 , Figure 6 and Fig. 9 As shown, the base 6 is detachably sleeved in the cartridge tube 2. Optionally, a second buckle 62 may be provided on the outer wall of the base 6, and a second buckle groove 28 for cooperating with the second buckle 62 may be correspondingly provided on the inner wall of the cartridge tube 2, so that the base 6 and the cartridge tube 2 are detachably connected by buckling the second buckle 62 in the second buckle groove 28; or,

[0069] A second buckle 62 is provided on the inner wall of the cartridge tube 2, and a second buckle groove 28 for cooperating with the second buckle 62 is correspondingly provided on the outer wall of the base 6, and the second buckle 62 is buckled into the second buckle groove 28, thereby realizing a detachable connection between the base 6 and the cartridge tube 2. It is understandable that, according to the actual situation, other connection methods can be used to realize the detachable connection between the base 6 and the cartridge tube 2, and the present invention is not limited here.

[0070] Specifically, in one embodiment of the present invention, Figure 3 , Figure 5 and Fig. 9As shown, a first groove 63 is provided on the outer wall of the base 6, and the first groove 63 is provided on the side of the second buckle 62 away from the suction nozzle assembly 1. The atomization device also includes a sealing ring 7 sleeved in the first groove 63, and the sealing ring 7 is provided between the base 6 and the inner wall of the cigarette cartridge tube 2. One end of the sealing ring 7 away from the suction nozzle assembly 1 protrudes toward the inner wall of the cigarette cartridge tube 2 to form a first protrusion 71, and the second buckle 62 and the first protrusion 71 are enclosed to form a limiting groove 64. The inner wall of the cigarette cartridge tube 2 protrudes toward the direction close to the sealing ring 7 to form a second protrusion 29, and the second protrusion 29 is embedded in the limiting groove 64. In this embodiment, when the second buckle 62 of the base 6 is buckled in the second buckle groove 28 of the cigarette cartridge tube 2, a compression assembly is formed between the cigarette cartridge tube 2 and the base 6 in a direction parallel to the assembly direction of the cigarette cartridge tube 2 and the base 6, so that the end face of the sealing ring 7 away from the suction nozzle assembly 1 is interference-fitted with the side of the first groove 63 close to the suction nozzle assembly 1 and is in a sealed state, and the side of the second protrusion 29 away from the suction nozzle assembly 1 is interference-fitted with the side of the limiting groove 64 close to the suction nozzle assembly 1 and is in a sealed state, thereby realizing a planar sealing structure formed between the base 6 and the inner wall of the cigarette cartridge tube 2 in a direction perpendicular to the assembly direction of the cigarette cartridge tube 2 and the base 6 to avoid oil leakage.

[0071] It is worth mentioning that the sealing connection between the cartridge tube 2 and the base 6 of the conventional atomizer device is a sealing structure formed by the interference fit between the inner wall of the cartridge tube 2 and the outer wall of the base 6. This structure easily causes the side wall of the cartridge tube 2 to be pushed outward by the interference fit, resulting in dimensional deformation (i.e., the diameter of the open end where the cartridge tube 2 and the base 6 are matched becomes larger), thereby causing oil leakage. The atomizer device of the embodiment of the present invention forms a planar sealing structure perpendicular to the assembly direction of the cartridge tube 2 and the base 6 between the base 6 and the inner wall of the cartridge tube 2 through the above arrangement, which does not cause the side wall of the cartridge tube 2 to be pushed outward by the interference fit, resulting in dimensional deformation.

[0072] Furthermore, if Figure 3 , Figure 5 and Fig. 9 As shown, in order to further increase the sealing strength between the base 6 and the cigarette bomb tube 2, the plane sealing method in the assembly direction parallel to the cigarette bomb tube 2 and the base 6 can be appropriately increased, such as the bottom surface of the second protrusion 29 close to the base 6 is interference fit with the bottom surface of the limiting groove 64 away from the cigarette bomb tube 2 to form a sealed state. In this embodiment, the sealing strength between the base 6 and the cigarette bomb tube 2 is mainly achieved by relying on the plane sealing method in the assembly direction perpendicular to the cigarette bomb tube 2 and the base 6, supplemented by the plane sealing method in the assembly direction parallel to the cigarette bomb tube 2 and the base 6, so as to avoid the side wall of the cigarette bomb tube 2 being subjected to the outward thrust due to the interference and causing dimensional deformation.

[0073] Specifically, in one embodiment of the present invention, Figure 3 , Figure 7 and Fig. 9 As shown, 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 groove 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 groove 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.

[0074] Furthermore, if Figure 3 , Figure 7 and Fig. 9 As shown, one end of the oil guide base 41 away from the base 6 extends toward opposite sides to form limiting steps 411, and the end surface of the hook 65 close to the sealing cover 3 is aligned 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 groove 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 base 6 and the sealing cover 3, so that a side of the oil guide 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 guide 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 .

[0075] Specifically, in one embodiment of the present invention, Figure 3 , Figure 7 and Fig. 9 As shown, the oil absorbing carrier 5 is spaced apart from the heating component 4 to prevent the oil absorbing carrier 5 from being burned. More specifically, the sealing cover 3 is provided with a limit column 35 extending in the direction toward the base 6, and the end surface of the limit 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 component 4 and being burned by the heat generated by the resistance heating element 42 when it is working.

[0076] Specifically, in one embodiment of the present invention, Figure 2 and Figure 3As shown, the atomizing device also includes a conductive electrode 8 that penetrates the base 6, and one end of the conductive electrode 8 extends into the atomizing chamber 66 and abuts against the resistance heating element 42, so as to supply power to the resistance heating element 42. Compared with the traditional atomizing device, the resistance heating element 42 of the embodiment of the present invention does not need to be provided with a conductive pin, so 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.

[0077] Specifically, in one embodiment of the present invention, the atomization device 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.

[0078] It is worth mentioning that through multiple 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.

[0079] See also Figure 3 , Figure 4 and Figure 8 The working process of the atomization device 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.

[0080] Another embodiment of the present invention provides an electronic cigarette, including the above-mentioned atomizing device and a power supply body for supplying power to the resistive heating element 42, wherein the power supply body supplies power to the resistive heating element 42 through the conductive electrode 8. Since the electronic cigarette of the embodiment of the present invention includes the above-mentioned atomizing device, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
