DETAILED DESCRIPTION

[0084] Referring to Figure 1 , the embodiment provides an atomizer 200, which comprises an oil cup 10, a suction nozzle 20 sleeved to a first end of the oil cup 10, and a cylindrical protective shell 120 sleeved to a second end of the oil cup 10.

[0085] Referring to Figures 1-3 , the atomizer 200 further comprises an air tube 90, a seal 60, a partition member 70 and an atomizing core 80 installed in the oil cup 10.

[0086] The seal 60 comprises a tubular first connecting portion 64 and a cylindrical first body 62 extending outward from an end of the first connecting portion 64. An outer periphery of the first body 62 is in sealing connection with an inner wall of the oil cup 10, for example, in the form of a sealing ring arranged on an outer wall of the first body 62, which is tightly pressed to the inner wall of the oil cup 10 to achieve sealing connection with the inner wall of the oil cup 10. An inner portion of the first connecting portion 64 is in communication with an inner portion of the first body 62. The seal 60 can be silica gel.

[0087] The spacer 70 is clamped between the seal 60 and the atomizing core 80. The spacer 70 comprises a tubular second connecting portion 74 and a cylindrical second body 72 extending outwardly from the end of the second connecting portion 74. The interior of the second connecting portion 74 communicates with the interior of the second body 72. The second connecting portion 74 extends into the first connecting portion 64 and is sealingly connected with the first connecting portion 64. The atomizing core 80 is mounted into the second body 72. One function of the spacer 70 is to separate the seal 60 from the atomizing core 80, preventing the material of the seal 60 from penetrating into the atomizing core 80 and causing the oil passage to be blocked. The spacer 70 can be made of stainless steel, dense ceramic or the like.

[0088] One end of the breather tube 90 is mounted into the mounting channel 14 of the first end of the oil cup 10 and is sealingly connected with the mounting channel 14, and the other end is mounted into the first connecting portion 64 and is sealingly connected with the first connecting portion 64. The outer wall of the breather tube 90 and the inner wall of the oil cup 10 form the oil storage cavity 12 for storing atomized oil. The bottom of the first body 62 is provided with a first oil inlet channel 66 communicating with the oil storage cavity 12, and the bottom of the second body 72 is provided with a second oil inlet channel 76 corresponding to the first oil inlet channel 66, so that the oil inlet surface of the atomizing core 80 is exposed to the oil storage cavity 12, and thus the atomized oil in the oil storage cavity 12 can enter the oil inlet surface of the atomizing core 80 through the first oil inlet channel 66 and the second oil inlet channel 76 to be heated and atomized by the atomizing core 80.

[0089] In this embodiment, the first oil inlet channel 66 is a ring-shaped through cavity surrounding the outside of the first connecting portion 64, and the second oil inlet channel 76 is a through hole. It can be understood that the first oil inlet channel 66 can also be, for example, a through hole, and the second oil inlet channel 76 can also be, for example, a ring-shaped through cavity.

[0090] The first connecting portion 64 is provided with a partition plate 642, and the two sides of the partition plate 642 are crimped by the breather tube 90 and the second connecting portion 74 respectively, thereby playing a sealing role to prevent air and oil leakage. The partition plate 642 is provided with air passing holes 6422 respectively communicating with the interior of the breather tube 90 and the interior of the second connecting portion 74, so as to facilitate the atomized gas mist to enter the breather tube 90.

[0091] The breather tube 90 is a stainless steel part, and the inner surface of the stainless steel part is smooth, which is beneficial to the condensate returning to the atomizing core 80 for secondary heating and atomization, thereby reducing the risk of suctioning the condensate.

[0092] In combination Figures 4-6As shown, the atomizing core 80 comprises an oil guide 82 and a heating element 84. The oil guide 82 has opposite first and second surfaces in the height direction. The second body 72 covers the first surface and the outer side surface of the oil guide 82. The second body 72 is clamped between the oil guide 82 and the first body 62 to separate the sealing member 60 and the oil guide 82. The first surface has an oil inlet surface, and the oil guide 82 is configured to guide the atomizing oil coming from the oil inlet surface to the second surface. The oil guide 82 is provided with an air outlet hole 86 penetrating through the first and second surfaces in the height direction, and the heating element 84 is arranged on the second surface of the oil guide 82. The air outlet hole 86 is in communication with the inner portion of the second connecting portion 74, so that the inner portion of the air guide tube 90 is in communication with the air outlet hole 86 through the air outlet hole 6422, the second connecting portion 74. Through this structure, the atomized aerosol heated by the oil guide 82 can be directly guided out of the air outlet hole 86, and the guiding-out process has no corner and the guiding-out path is short, which can reduce the generation of condensate and avoid the phenomenon that the user inhales the condensate. In addition, this structure has a fast oil supply speed and a large atomizing area, so that the user has a better smoking experience.

[0093] The first surface of the oil guide 82 is provided with an oil inlet groove 88 corresponding to the second oil inlet channel 76, and the bottom surface and the wall surface of the oil inlet groove 88 serve as the oil inlet surface. The atomizing oil in the oil storage cavity 12 can enter the oil inlet groove 88 through the first oil inlet channel 66 and the second oil inlet channel 76, and then enter the oil guide 82 through the bottom surface and the wall surface of the oil inlet groove 88 for heating and atomization by the oil guide 82. The oil inlet groove 88 can increase the oil inlet speed. In this embodiment, the oil inlet groove 88 is triangular. There are two oil inlet grooves 88, which are respectively located on the two sides of the air outlet hole 86. The two oil inlet grooves 88 can further increase the oil inlet speed and balance the oil consumption on both sides of the oil guide 82, thereby ensuring uniform atomization. The number of the second oil inlet channels 76 corresponds to the number of the oil inlet grooves 88.

[0094] In this embodiment, the inner diameter of the oil inlet groove 88 gradually decreases in the direction from the first surface to the second surface of the oil guide 82, which can further increase the oil inlet speed. The inner diameter of the air outlet hole 86 gradually increases in the direction from the first surface to the second surface of the oil guide 82, which can increase the air outlet speed.

[0095] In this embodiment, the axial projection shape of the oil guide 82 is oval. It can be understood that the shape of the oil guide 82 can also be, for example, rectangular, circular, and the like, as shown. Figures 7-10 It can be understood that the structure of the oil guide 82 can also be composed of a circular portion and two rectangular portions arranged on both sides of the circular portion, and in this structure, the air outlet hole 86 is arranged on the circular portion. The shape of the oil guide 82 can be set according to actual conditions. The shape of the oil inlet groove 88 can also be, for example, arc-shaped, rectangular, annular, and the like, as shown. Figure 7 Figure 9 and​Figure 10 The number of the oil inlets 88 can also be, for example, one, four, three, etc. Figure 8 and Figure 10 As shown, when the number of the oil inlets 88 is one, the oil inlet 88 is an annular groove, which is arranged around the outer periphery of the air outlet hole 86. The number and shape of the oil inlets 88 can be set according to actual conditions.

[0096] In this embodiment, the length of the oil guide 82 is greater than the height of the oil guide 82, which can reduce the axial volume of the atomizing core 80, and the heating element 84 extends along the length direction of the oil guide 82 on the second surface. It can be understood that the length of the oil guide 82 can also be greater than twice the height of the oil guide 82.

[0097] In this embodiment, the oil guide 82 is a porous ceramic. The height of the heating element 84 is 0.05-0.3 mm, preferably 0.08-0.12 mm. The resistance of the heating element 84 is 1.0-2.0 ohms.

[0098] In this embodiment, the heating element 84 is a sheet shape and is attached to the second surface. The heating element 80 includes a first portion 8422 and a second portion 8424 connected to each other, the first portion 8422 is located on the second surface and passes around the air outlet hole 86. The second portion 8424 is two, which are located on the second surface and are located on both sides of the air outlet hole 86 and are symmetric about the center of the air outlet hole 86, and the two second portions 8424 are connected to both sides of the first portion 8422 respectively. The heating element 84 further includes two terminal portions 844, which are connected to the sides of the two second portions 8424 away from the first portion 8422 respectively. The polarities of the two terminal portions 844 are opposite. The two terminal portions 844 are used to be electrically connected to the first electrode 112 and the second electrode 114 to achieve the power supply of the heating element 84 by the external power supply.

[0099] In this embodiment, the two terminal portions 844 are electrodes of a sheet shape and are located on the second surface of the oil guide 82. It can be understood that the two terminal portions 844 can also be two pins of opposite polarities extending in the axial direction of the atomizing core 80, and the two pins are used to be electrically connected to the first electrode 112 and the second electrode 114, which can also achieve the power supply of the heating element 84 by the external power supply.

[0100] The second portion 8424 includes a plurality of conductive segments 8424a, which are connected in sequence and are connected in series between the two terminal portions 844.

[0101] The two adjacent conductive segments 8424a are connected at one end and separated from each other at the other end, and the spacing between the mutually parallel ends of the two adjacent conductive segments is 0.2-0.6 mm, preferably 0.4 mm.

[0102] ​The width of the conductive segment 8424a is 0.1-0.4 mm, preferably 0.2 mm.

[0103] In other embodiments, the heating element 84 can be S-shaped, straight, zigzag, wavy, sawtooth, spiral, circular, or rectangular, etc. The shape of the heating element 84 can be set according to the actual situation.

[0104] Preferably, the heating element 84 and the oil guiding element 82 are integrally sintered for ease of manufacturing. When the spacer 70 is a dense ceramic part, the spacer 70 and the oil guiding element 82 can also be integrally sintered.

[0105] In this embodiment, the heating element 84 is a metal component, which is etched onto the second surface of the oil guide component 82. The edge of the heating element 84 is provided with a gripper portion 8426 (see...). Figure 5 This design prevents the heating element 84 from warping. Preferably, the gripper portion 8426 is located at the connection point of two adjacent conductive segments 8424a. The gripper portion 8426 is perpendicular to the heating element 84 and embedded in the oil guide member 82, with the height of the gripper portion 8426 greater than the thickness of the heating element 84. In other embodiments, the gripper portion 8426 is perpendicular to the heating element 84 and covers the outer surface of the oil guide member 82, which also achieves the effect of preventing the heating element 84 from warping.

[0106] In other embodiments, the heating element 84 is a resistive paste layer, which is applied to the second surface of the oil guide element 82 by means of printing, coating, soaking or spraying, etc.

[0107] The atomizer 200 of the present invention further includes a bracket 40 and an oil suction member 50 mounted to the second end of the oil cup 10. The bracket 40 is located on the side of the oil guide member 82 having the second surface.

[0108] The seal 60 is mounted to the bracket 40, which supports the seal 60. At one end of the bracket 40 near the seal 60, there is a bowl-shaped air inlet chamber 42 corresponding to the atomizing core 80.

The end of the oil suction component 50 near the seal 60 is provided with a storage cavity 52 corresponding to the air outlet 86 of the atomizing core. The storage cavity 52 is located in the air inlet position 422 at the bottom of the air inlet cavity 42 and is provided with a storage cavity 521. The storage cavity 521 is used to retain the condensate flowing down from the air outlet 86 and to prevent oil splashing, thereby reducing the risk of oil leakage.

[0110] Two sides of the storage cavity 521 are formed with grooves 522 (see Figure 2 ), the grooves 522 and the inner wall of the air inlet hole 422 form an air inlet channel, the air inlet channel communicates with the air inlet cavity 42. The oil absorption member 50 is provided with a through groove 54, the through groove 54 communicates with the air inlet channel. The bottom of the protective shell 120 is provided with an air inlet hole 122 which communicates with the through groove 54, thus external air can enter the air inlet cavity 42 through the air inlet hole 122, the through groove 54, the air inlet channel, then enter the air outlet hole 86, and the air entering the air outlet hole 86 mixes with the aerosol after the oil guide member 82 heats and atomizes, then enters the air pipe 90 through the air passing hole 6422 of the second connecting part 74 and the baffle 642.

[0111] In this embodiment, the inner wall of the air inlet cavity 42 is smooth and arc-shaped, which can reduce the rotation of air in the air inlet cavity 42, effectively increase the utilization rate of air and reduce the generation of condensate.

[0116] In this embodiment, there are two oil fill holes 16, one on either side of the first end of the oil cup 10, and the number of mountings 34 and spigots 24 corresponds to the number of oil fill holes 16. The provision of two oil fill holes 16 means that when one is being used to fill the oil cup 10 with atomised oil, the other can be used to vent air, avoiding the build-up of pressure within the oil cup 10 which can cause oil to leak out. The provision of two oil fill holes 16 also helps to prevent mistakes being made during assembly.

[0117] The end of the suction nozzle 20 furthest from the oil cup 10 is provided with an air intake passage 22 for the user to draw on.
