The main housing 1, bottom cover assembly 3, and bracket 4 are typically made of plastic materials such as plastic, possessing plasticity and a good modulus of elasticity.

[0046] The atomizer provided in this embodiment has a sealing element at the connection between the bracket and the main housing and the cover assembly to improve the sealing performance, prevent liquid leakage inside the atomizer during assembly, transportation and use, and ensure the atomization effect.

[0047] Please refer to Figure 6 In one embodiment, the first sealing member 51 is sleeved on the end of the extension 42 away from the support 41, and the side of the first sealing member 51 away from the extension 42 is interference-fitted with the bottom cover assembly 3.

[0048] In some implementations, such as Figure 3 and Figure 6As shown, the first sealing element 51 is sleeved on the lower end of the extension 42 away from the support 41, that is, the lower end of the extension 42 is embedded in the first sealing element 51. The outer side of the first sealing element 51 in the radial X direction is interference-fitted with the bottom cover assembly 3. Therefore, this embodiment adopts a sleeve installation method to improve the sealing reliability between the first sealing element 51, the bracket 4, and the bottom cover assembly 3.

[0049] Please refer to Figure 6 In one embodiment, the extension 42 includes an extension body 421 and an end protrusion 422; one end of the extension body 421 is connected to the support 41, and the other end is connected to the end protrusion 422. The extension body 421 abuts against the inner wall of the main housing 1. The first sealing member 51 is sleeved on the end protrusion 422. The bottom cover assembly 3 is snap-fitted to the main housing 1 on the side opposite to the first sealing member 51.

[0050] In some implementations, such as Figure 3 and Figure 6 As shown, the upper end of the extension body 421 along the Z direction is connected to the support part 41, and the lower end is connected to the end protrusion 422. The outer side of the extension body 421 along the X direction abuts against the inner wall of the main housing 1. The first sealing member 51 is sleeved on the end protrusion 422, and the bottom cover assembly 3 is snap-fitted to the outer side of the main housing 1 along the radial X direction.

[0051] In some embodiments, the first sealing member 51 includes a fifth sealing portion 511 and a sixth sealing portion 512, which are annular and coaxial. The structure formed by the fifth sealing portion 511 and the sixth sealing portion 512 is sleeved on the end protrusion 422. The fifth sealing portion 511 is located radially inner to the end protrusion 422, and the sixth sealing portion 512 is located radially outer to the end protrusion 422. The liquid-absorbing member 7 and the power supply 81 are disposed within the battery compartment 102. The liquid-absorbing member 7 is used to absorb condensate, and the power supply 81 supplies power to the heating element 9. A second air guide channel 71 is provided within the liquid-absorbing member 7, communicating with the air inlet 321. The fifth sealing portion 511 is sealed between the power supply 81 or the liquid-absorbing member 7 and the end protrusion 422. The sixth sealing portion 512 is interference-fitted between the first bottom cover 31 of the bottom cover assembly 3 and the end protrusion 422. In this embodiment, the sixth sealing part 512 is interference-fitted with at least one of the end protrusion 422 and the bottom cover assembly 3 to seal the gap between the first bottom cover 31 and the bracket 4. This prevents liquid that may enter the battery compartment 102 from leaking from the connection between the main housing 1, the bracket 4 and the bottom cover assembly 3.

[0052] Please refer to Figure 2 and Figure 6In one embodiment, the support portion 41 is provided with a positioning groove 411, and the second sealing member 52 includes a first sealing portion 521 and a second sealing portion 522 disposed inside the first sealing portion 521. The second sealing portion 522 is embedded in the positioning groove 411, and the first sealing portion 521 is sealed to the main housing 1.

[0053] In some implementations, such as Figure 6 As shown, the support portion 41 is provided with a positioning groove 411. The second sealing member 52 includes a first sealing portion 521 and a second sealing portion 522. The second sealing portion 522 surrounds the outside of the first sealing portion 521 and is embedded in the positioning groove 411. The outer side of the first sealing portion 521 is radially press-fitted with the main housing 1. Therefore, this embodiment improves the connection reliability between the second sealing member 52 and the bracket 4 by using the positioning groove for fixing. Furthermore, the support portion 41 is provided with a positioning post 412, which passes through the second sealing member 52 to position the second sealing member 52, thereby improving the fixing reliability.

[0054] Please refer to Figure 2 and Figure 6 In one embodiment, the support portion 41 includes a first support frame 413 and a second support frame 414; the first support frame 413 is disposed inside the second support frame 414, and both the first support frame 413 and the second support frame 414 are connected to the extension portion 42. A positioning groove 411 is formed between the first support frame 413, the second support frame 414 and the extension portion 42, and the first sealing portion 521 is interference-fitted between the second support frame 414 and the main housing 1.

[0055] In some implementations, such as Figure 2 and Figure 6 As shown, the positioning groove 411 is defined by the structure of the support frame. The first support frame 413 is disposed inside the second support frame 414, and the lower ends of both the first support frame 413 and the second support frame 414 are connected to the extension body 421 of the extension portion 42. The positioning groove 411 is formed between the first support frame 413, the second support frame 414 and the extension portion 42. The first support frame 413 and the second support frame 414 form the sides of the positioning groove 411, and the extension body 421 of the extension portion 42 forms the bottom of the positioning groove 411. The first sealing part 521 is interference-fitted radially outward between the second support frame 414 and the main housing 1.

[0056] Please refer to Figure 5 and Figure 6In one embodiment, the atomizer further includes a mouthpiece 2, an atomizing component 6, and a third sealing member 53; the mouthpiece 2 is integrally connected to the main housing 1, and the mouthpiece 2 has a mouthpiece air passage 21 inside. The atomizing component 6 is located in the liquid storage chamber 101, and the atomizing component 6 has a first guiding air passage 60. The first end of the mouthpiece air passage 21 has an air outlet 211, and the second end of the mouthpiece air passage 21 is connected to the first guiding air passage 60. The third sealing member 53 seals and isolates the gap formed between the first guiding air passage 60 and the mouthpiece air passage 21 from the liquid storage chamber 101.

[0057] In some embodiments, the atomizing component 6 is located within the liquid storage chamber 101, and the atomizing component 6 has a first airflow channel 60 inside. The mouthpiece 2 is integrally connected to one end of the main housing 1, and the mouthpiece 2 has a mouthpiece airflow channel 21 inside. The first end, i.e., the upper end, of the mouthpiece airflow channel 21 has an air outlet 211, and the second end communicates with the first airflow channel 60. The atomizing component 6 heats and atomizes the oil to form smoke, which flows through the first airflow channel 60 and the mouthpiece airflow channel 21, and is discharged from the air outlet 211. The main housing 1 includes an outer shell 11 and an inner shell 12, which are integrally connected to form the main housing 1. The inner shell 12 is located on the outer periphery of the mouthpiece airflow channel 21. Since there may be an air gap at the connection between the first airflow channel 60 and the mouthpiece airflow channel 21, there is a certain risk of liquid leakage. The third seal 53 seals and isolates the air gap formed between the first airflow channel 60 and the mouthpiece airflow channel 21 from the liquid storage chamber 101. Specifically, the third sealing element 53 can be sealed between the first airflow channel 60, the mouthpiece airflow channel 21, and the inner shell 12, preventing liquid in the liquid storage chamber 101 from leaking between the first airflow channel 60 and the mouthpiece airflow channel 21, and from leaking out of the atomizer from the mouthpiece airflow channel 21. Therefore, this embodiment improves the sealing performance at the air outlet of the atomizer by providing the third sealing element 53.

[0058] Please refer to Figure 6 In one embodiment, the atomizing component 6 includes a liquid guide 61, a support tube 62, and an atomizing core 63. The liquid guide 61 and the atomizing core 63 are fixed inside the support tube 62. The liquid guide 61 has a first airflow channel 60, and the atomizing core 63 is disposed inside the first airflow channel 60. A third sealing member 53 is sleeved on the end of the support tube 62. The third sealing member 53 includes a third sealing part 531 and a fourth sealing part 532. The third sealing part 531 is sealed between the end of the support tube 62 and the main housing 1, and the fourth sealing part 532 is sealed between the gap formed between the first airflow channel 60 and the mouthpiece airflow channel 21 and the end of the support tube 62.

[0059] In some implementations, such as Figure 4 and Figure 6As shown, the liquid guide 61 and the atomizing core 63 are fixed inside the support tube 62. The liquid guide 61 has a first airflow channel 60, and the atomizing core 63 is disposed within the first airflow channel 60. The support tube 62 serves to fix and support the liquid guide 61 and the atomizing core 63, and isolates the liquid guide 61 and the atomizing core 63 from the oil in the liquid storage chamber 101. The support tube 62 is usually made of steel pipe, with its end protruding from the liquid guide 61 and located on the outer periphery of the second end of the nozzle airflow channel 21. The third sealing member 53 is sleeved on the end of the support tube 62, that is, the end of the support tube 62 is embedded in the third sealing member 53 to improve the fixing reliability of the third sealing member 53. The third sealing member 53 includes a third sealing part 531 and a fourth sealing part 532. Both the third sealing part 531 and the fourth sealing part 532 are annular and coaxial. The fourth sealing part 532 is located on the inner side of the support tube 62 in the radial direction, and the third sealing part 531 is located on the outer side of the support tube 62 in the radial direction. The third sealing part 531 is sealed between the inner wall of the main housing 1 and the end of the support tube 62. The inner wall of the main housing 1 is the inner shell 12. The third sealing part 531 is provided with an interference protrusion 50, which is interference-fitted with at least one of the main housing 1 and the support tube 62 to prevent liquid in the liquid storage chamber 101 from seeping out through the gap between the inner wall of the main housing 1 and the outer wall of the support tube 62 into the space between the first guide airway 60 and the suction nozzle airway 21. The fourth sealing part 532 is sealed between the gap formed between the first guide airway 60 and the suction nozzle airway 21 and the end of the support tube 62. In this embodiment, an interference protrusion 50 is provided on the fourth sealing part 532, which is connected to the outer wall of the mouthpiece air passage 21 by interference fit, so as to prevent the liquid in the liquid storage chamber 101 from leaking into the gap between the first guide air passage 60 and the mouthpiece air passage 21, thereby improving the sealing of the atomizer's air intake end.

[0060] Please refer to Figure 6 In one embodiment, the atomizer further includes a fifth seal 55; the fifth seal 55 is interference-fitted into the mouthpiece airway 21, and the fifth seal 55 is detachably connected to the mouthpiece airway 21.

[0061] In some implementations, such as Figure 6As shown, a fifth sealing element 55 is detachably sealed within the mouthpiece air passage 21 of the mouthpiece 2. The fifth sealing element 55 is detachably connected to the mouthpiece air passage 21, and it has an interference fit protrusion 50 that fits against the inner wall of the mouthpiece air passage 21. A crimping portion 551 is provided at the end of the fifth sealing element 55, with an outer diameter larger than the diameter of the mouthpiece air passage 21, enhancing the sealing effect. During assembly and transportation, and before consumer use, the fifth sealing element 55 is sealed within the mouthpiece air passage 21, preventing liquid leakage from the atomizer and affecting product quality before use. When needed, the fifth sealing element 55 must be removed before using the mouthpiece 2. Therefore, by providing a detachable fifth sealing element 55, the sealing performance of the atomizer is further improved before consumer use, preventing liquid leakage from the atomizer.

[0062] Please refer to Figure 6 In one embodiment, the atomizer further includes a fourth seal 54 and a circuit board 82; the bottom cover assembly 3 includes a first bottom cover 31 and a second bottom cover 32, the first bottom cover 31 is connected to the main housing 1, the second bottom cover 32 is connected to the inside of the first bottom cover 31, the circuit board 82 is located inside the battery compartment 102, the fourth seal 54 is interference-fitted between the circuit board 82 and the second bottom cover 32, and the fourth seal 54 is interference-fitted with the first bottom cover 31.

[0063] In some implementations, such as Figure 6 As shown, the bottom cover assembly 3 includes a first bottom cover 31, a second bottom cover 32, and a sliding member 33. The first bottom cover 31 is fastened to the main housing 1. The second bottom cover 32 is partially embedded in the first bottom cover 31. The second bottom cover 32 has an air inlet 321, which is the inlet for outside air. The sliding member 33 is located inside the first bottom cover 31 and is slidably connected to the second bottom cover 32. During the sliding process, the degree of obstruction of the air inlet 321 can be changed to adjust the air intake and meet personalized usage needs. The air inlet 321 is connected to the second airflow channel 71 of the liquid suction member 7. Gas enters the atomizer from the air inlet 321 through the second airflow channel 71. The circuit board 82 is located at the bottom of the battery compartment 102. A fourth sealing member 54 is sealed between the circuit board 82 and the second bottom cover 32 to prevent liquid that may enter the battery compartment 102 from leaking through the gap between the circuit board 82 and the second bottom cover 32. The fourth seal 54 has a through hole of the same size as the air inlet 321, which facilitates the formation of a smooth air intake channel.

[0064] In some implementations, such as Figure 6As shown, the fourth sealing element 54 has an interference protrusion 50 along its radially outer side, which is interference-fitted with the first bottom cover 31 to seal, improving the sealing performance between the first bottom cover 31 and the second bottom cover 32. This prevents liquid in the atomizer from leaking out from the gap between the first bottom cover 31 and the second bottom cover 32, further improving the atomizer's sealing performance and ensuring atomization effect.

[0065] Please refer to Figure 6 In one embodiment, the atomizer further includes a sixth seal 56; an air inlet 321 is provided on the second bottom cover 32, the sixth seal 56 is interference-fitted into the air inlet 321, and the sixth seal 56 is detachably connected to the air inlet 321.

[0066] In some implementations, such as Figure 6 As shown, a sixth seal 56 is detachably connected to the air inlet 321, and the sixth seal 56 is interference-fitted with the air inlet 321. During assembly and transportation, and before consumer use, the sixth seal 56 is securely inserted into the air inlet 321 to prevent liquid leakage from the air inlet 321, which could affect product quality. When needed, the sixth seal 56 is removed, allowing air to enter the air inlet 321. Therefore, by providing a detachable sixth seal 56, the atomizer's sealing performance is further improved before consumer use, preventing liquid leakage from inside the atomizer.

[0067] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
