Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol atomization, and in particular to an aerosol generating device. BACKGROUND

[0002] The aerosol generating device is a device that atomizes liquid into aerosol by heating, and is widely used in medical, industrial, agricultural, scientific research, electronic cigarette and other fields.

[0003] The aerosol generating device is generally divided into two types: an atomization assembly separation type and an atomization assembly combination type. In the atomization assembly separation type, the atomization assembly needs to be activated before use. After activation, the atomization assembly is in communication with the oil storage space of the atomizer, and the aerosol generating oil can enter the atomization assembly. When the atomizer is not in use, the atomization assembly is isolated from the oil storage space, which can effectively prevent the aerosol generating oil from leaking from the atomization channel of the atomization assembly. However, the atomization assembly separation type atomizer is prone to be mistakenly started in daily life when not in use, the electric heating element in the atomization assembly is dry, and the atomization assembly is prone to be damaged.

[0004] To solve the above-mentioned mistaken starting problem, some aerosol generating devices are provided with a switching element on the atomizer circuit, which is linked with the isolating piece of the atomizer. The isolating piece can realize the communication and isolation of the atomization channel and the oil storage space. When the isolating piece is in the isolation position, the switching element disconnects the atomizer circuit, so that the atomizer circuit cannot be mistakenly started, and the electric heating element cannot be started, so that the atomizer is not prone to dry burning. When the isolating piece is in the communication position, the switching element connects the atomizer circuit, which does not affect the normal work of the atomizer. However, a linkage mechanism needs to be provided between the switching element and the isolating piece, which increases the structural complexity and the cost of the switching element and the linkage mechanism.

[0067] Referring to Figure 4 And Figure 11 In an embodiment, the barrier component 3 has a connecting channel 31, a first sealing portion 32, a second sealing portion 33, an oil passage 34, and an air passage 35. The first sealing portion 32 and the second sealing portion 33 are located on the inner wall of the connecting channel 31. The oil passage 34 is connected to the connecting channel 31 and the atomization channel 12. The air passage 35 is connected to the connecting channel 31 and the atomization channel 12.

[0068] At least part of the linkage component 4 is movably arranged in the connecting channel 31.

[0069] When the linkage component 4 is in the conduction position, the oil outlet 411 of the first oil inlet channel is connected to the oil passage 34 to conduct the first oil inlet channel 41 and the atomization channel 12. The air outlet 421 of the first air inlet channel is connected to the air passage 35 to conduct the first air inlet channel 42 and the atomization channel 12.

[0070] When the linkage component 4 is in the isolation position, the first sealing portion 32 blocks the oil outlet 411 of the first oil inlet channel to seal the oil outlet 411 of the first oil inlet channel, thereby limiting the oil in the oil storage cavity 11 from flowing out of the oil outlet 411 of the first oil inlet channel; the second sealing portion 33 blocks the air outlet 421 of the first air inlet channel to seal the air outlet 421 of the first air inlet channel, thereby limiting the external air from flowing out of the air outlet 421 of the first air inlet channel.

[0071] Referring to Figure 11 In an embodiment, when the linkage component 4 is in the isolation position, the first sealing portion 32 is arranged around the oil outlet 411 of the first oil inlet channel, i.e., the first sealing portion 32 has a ring structure, and the first sealing portion 32 abuts against the outer wall of the linkage component 4. In this way, the first sealing portion 32 can reliably seal the oil outlet 411 of the first oil inlet channel, and the contact area between the first sealing portion 32 and the linkage component 4 can be reduced, so as not to hinder the switching of the linkage component 4 between the conduction position and the isolation position, and ensure smoother movement of the linkage component 4.

[0072] Of course, in other embodiments, the first sealing portion 32 can also have an overall structure capable of covering the oil outlet 411 of the first oil inlet channel, so as to reliably seal the oil outlet 411 of the first oil inlet channel.

[0073] Referring to Figure 11 In an embodiment, when the linkage component 4 is in the isolation position, the second sealing portion 33 is arranged around the oil outlet 411 of the first oil inlet channel, i.e., the second sealing portion 33 has a ring structure, and the second sealing portion 33 abuts against the outer wall of the linkage component 4.

[0074] Of course, in other embodiments, the second sealing portion 33 can also have an overall structure capable of covering the oil outlet 411 of the first oil inlet channel, so as to reliably seal the oil outlet 411 of the first oil inlet channel.

[0075] Referring to Figure 12In an embodiment, the inner wall of the connecting channel 31 is provided with a third sealing portion 36 and a fourth sealing portion 37. The third sealing portion 36 is arranged around the oil passage 34, and the third sealing portion 36 abuts against the outer wall of the linkage component 4 to press the third sealing portion 36 and the outer wall of the linkage component 4, so that the third sealing portion 36 seals the gap between the blocking component 3 and the linkage component 4, prevents oil leakage, and ensures that the oil in the oil storage cavity 11 can be efficiently output to the atomization channel 12 through the oil passage 34. The fourth sealing portion 37 is arranged around the air passage 35, and the fourth sealing portion 37 abuts against the outer wall of the linkage component 4 to press the fourth sealing portion 37 and the outer wall of the linkage component 4, so that the fourth sealing portion 37 seals the gap between the blocking component 3 and the linkage component 4, prevents air leakage, and ensures that the air output by the first air inlet channel 42 can be efficiently output to the atomization channel 12 through the air passage 35.

[0076] In an embodiment, the blocking component 3 is made of silica gel material, and the blocking component 3, the first sealing portion 32, the second sealing portion 33, the third sealing portion 36, and the fourth sealing portion 37 are integrally arranged together, i.e., the blocking component 3, the first sealing portion 32, the second sealing portion 33, the third sealing portion 36, and the fourth sealing portion 37 are made by integral molding, so that the blocking component 3 has better sealing performance. By pressing the blocking component 3 and the support component 1, the gap between the blocking component 3 and the support component 1 can be sealed, preventing oil or air from leaking from the gap between the blocking component 3 and the support component 1, and improving the sealing performance between the first sealing portion 32 and the blocking component 3, between the second sealing portion 33 and the blocking component 3, between the third sealing portion 36 and the blocking component 3, and between the fourth sealing portion 37 and the blocking component 3.

[0077] Of course, in other embodiments, the first sealing portion 32, the second sealing portion 33, the third sealing portion 36, and the fourth sealing portion 37 can be components independent of the blocking component 3, i.e., the first sealing portion 32, the second sealing portion 33, the third sealing portion 36, the fourth sealing portion 37, and the blocking component 3 are arranged in a split manner.

[0083] When the linkage component 4 is in the isolation position, the third positioning part 51 cooperates with the second positioning part 14 to limit the linkage component 4 in the isolation position, so as to prevent the linkage component 4 from being randomly removed from the isolation position, thereby ensuring that the linkage component 4 can be reliably maintained in the isolation position.

[0084] Referring to Figure 6 and Figure 16 In an embodiment, the number of the first positioning parts 13 is at least two, and the at least two first positioning parts 13 are arranged at intervals along the movement path of the linkage component 4.

[0089] Of course, in other embodiments, the linkage component 4 can also be arranged on the supporting component 1 in a moving manner, and the linkage component 4 is switched between the on position and the isolation position by moving the linkage component 4.

[0096] The aerosol generating device further comprises:

[0097] The limiting component 6 is sleeved between the second end of the linkage component 4 and the operation knob 5, and the limiting component 6 is located in the supporting component 1 and can abut against the supporting component 1, so as to limit the linkage component 4 from being separated from the supporting component 1, thereby reliably arranging the linkage component 4 on the supporting component 1.

[0098] Referring to Figure 15In an embodiment, the linkage component 4, the operation knob 5 and the limiting component 6 are separately arranged, the outer wall of the linkage component 4 is provided with a first positioning groove 43;

[0099] At least part of the operation knob 5 is inserted into the first air inlet channel 42, and the operation knob 5 is provided with a first positioning protrusion 52.

[0100] The limiting component 6 is provided with a second positioning protrusion 61 at one end, and the second positioning protrusion 61 and the first positioning groove 43 are in interference fit, so that the limiting component 6 and the operation knob 5 are reliably connected together. The outer wall of the other end of the limiting component 6 is provided with a second positioning groove 62, and the second positioning groove 62 and the first positioning protrusion 52 are in interference fit, so that the limiting component 6 and the operation knob 5 are reliably connected together.
