[0030] See also Figure 1 and Figure 2 In one embodiment, the present application provides a liquid leakage-proof electronic atomizer, comprising:

[0031] The shell 10 may be made of plastic, and an air inlet 11 and an air outlet 12 are provided on the outer surface of the shell 10. Furthermore, the shell 10 is made of transparent plastic, so that the remaining amount of the aerosol product inside the oil storage chamber 20 can be directly observed from the outside, which is convenient for users to replace or add aerosol products even if necessary, and is more convenient to use.

[0032] The atomizing assembly 40 is disposed in the housing 10, and an oil inlet hole 411 is disposed on the side of the atomizing assembly 40;

[0033] The oil storage chamber 20 is provided in the housing 10. The oil storage chamber 20 is used to store the aerosol product. The aerosol product in the oil storage chamber 20 enters the atomization assembly 40 through the oil inlet hole 411.

[0034] The base 80 is disposed in the shell 10, and one side of the base 80 abuts against a side of the atomizer assembly 40 away from the oil inlet hole 411, and the other opposite side of the base 80 is spaced apart from the inner wall of the shell 10 to form a leak-proof cavity 50, which is connected to the oil inlet hole 411.

[0035] The atomizing assembly 40 is used to heat the aerosol product infiltrated into the oil storage chamber 20 to form an aerosol, which is then inhaled by a person through the air outlet 12. The base 80 can be made of plastic material, and a connecting channel (not shown) can be provided between the leak-proof chamber 50 and the oil inlet 411. The leak-proof chamber 50 is indirectly connected to the oil inlet 411 through the connecting channel, and excess aerosol products can enter the leak-proof chamber 50 through the connecting channel, thereby preventing excessive aerosol products from entering the atomizing assembly 40 and flowing out through the air inlet 11 under the action of gravity.

[0036] In this way, part of the leaked aerosol product can be temporarily stored in the leak-proof cavity 50 and is not likely to flow out through the air outlet 12 to cause leakage, so that the electronic atomizer is not likely to leak oil and is more convenient to use.

[0037] See also Figure 2 and Figure 3 In one embodiment, the electronic atomizer further includes a first oil guide body 60, a portion of which covers the oil inlet hole 411, and the aerosol product in the oil storage chamber 20 penetrates into the first oil guide body 60, and then passes through the oil inlet hole 411 into the atomizing assembly 40, and another portion of the first oil guide body 60 is placed in the anti-leakage chamber 50. The first oil guide body 60 can be made of a material that is convenient for oil conduction, such as cotton fiber. Through the first oil guide body 60, at least part of the aerosol product that has penetrated too much can be guided through the first oil guide body 60 to the anti-leakage chamber 50 for temporary storage, preventing excessive aerosol products from entering the atomizing assembly 40 and flowing out through the air inlet hole 11 under the action of gravity.

[0038] See also Figure 2 and Figure 3 In one embodiment, the base 80 includes a support seat 81 and a protrusion 82, the first mounting hole 821 is provided on the support seat 81, the protrusion 82 is provided on the support seat 81, a mounting portion 83 is provided on one side of the protrusion 82, and one end of the atomization assembly 40 away from the support seat 81 is connected to the mounting portion 83.

[0039] The support seat 81 and the protrusion 82 can be designed as an integrally formed structure. The protrusion 82 can be arranged at the end of the support seat 81 away from the bracket 70. The mounting portion 83 can be designed as an integrally formed structure with the protrusion 82. The mounting portion 83 can be a claw or a hole. The end of the atomizer assembly 40 away from the support seat 81 is positioned by the mounting portion 83, making the installation of the atomizer assembly 40 more convenient.

[0040] See also Figure 5In one embodiment, the mounting portion 83 is provided with a second mounting hole 84 , and one end of the atomization assembly 40 away from the support seat 81 is placed in the second mounting hole 84 .

[0041] The interior of the second mounting hole 84 abuts against the outer side surface of the end of the atomizer assembly 40 , thereby realizing rapid positioning and assembly of the atomizer assembly 40 , making the assembly of the electronic atomizer more convenient.

[0042] See also Figure 5 In one embodiment, the mounting portion 83 is spaced apart from the support seat 81, and the first mounting hole 821 and the second mounting hole 84 are arranged opposite to each other. The first mounting hole 821 and the second mounting hole 84 can both be circular holes. By arranging the first mounting hole 821 and the second mounting hole 84 opposite to each other, the two ends of the atomizer assembly 40 can be quickly assembled into the first mounting hole 821 and the second mounting hole 84.

[0043] See also Figure 2 In one embodiment, the electronic atomizer further includes a bracket 70, which is located in the housing 10. The bracket 70 is provided with a lower oil channel 71, one end of the lower oil channel 71 is connected to the oil storage chamber 20, and the other end is provided with a through hole 72, and the through hole 72 is connected to the oil inlet hole 411.

[0044] The bracket 70 can be made of plastic material and is located below the oil storage chamber 20. The aerosol product in the oil storage chamber 20 can flow into the through hole 72 through the lower oil channel 71 under the action of gravity, penetrate into the interior of the atomization component 40 to be heated to form an aerosol, and the aerosol finally passes through the ventilation pipe 30 and the air outlet 12 so that the user can inhale.

[0045] See also Figure 2 and Figure 4 In one embodiment, two pressing portions 73 are provided on the side of the bracket 70 , and the two pressing portions 73 are arranged vertically opposite to each other and spaced apart. The bracket 70 and the two pressing portions 73 form a receiving groove 74 , and the end of the pressing portion 73 is placed in the anti-leakage cavity 50 .

[0046] The pressing portion 73 can facilitate the installation and positioning of the first oil guide body 60, and the abutment of the first oil guide body 60 and the atomizer assembly 40 can be pressed to make the connection between the first oil guide body 60 and the atomizer assembly 40 more tightly abutted, preventing the first oil guide body 60 from being located at the outer edge of the oil inlet hole 411 and the through hole 72 to form a gap, and the inner wall of the accommodating groove 74 forms a certain pressure on the abutment of the first oil guide body 60, so that the first oil guide body 60 is located between the oil inlet hole 411 and the through hole 72. The porosity is greater than the porosity of the first oil-conducting body 60 at the point where it is pressed, so that the aerosol product in the oil storage chamber 20 mainly penetrates into the interior of the atomizing assembly 40 through the through hole 72, the first oil-conducting body 60, and the oil inlet hole 411 in sequence, forming an effective oil lock. Excess aerosol product will penetrate into the anti-leakage chamber 50 for storage, and will also be sucked back through the first oil-conducting body 60 located in the receiving groove 74 for use. While preventing oil leakage, the number of puffs can be guaranteed to a greater extent, making the electronic atomizer more convenient to use.

[0047] See also Figure 4 In one embodiment, a first leakage-proof groove 75 is provided on a side surface of the bracket 70 and an outer side surface of the pressing portion 73 , and the first leakage-proof groove 75 is communicated with the leakage-proof cavity 50 .

[0048] There can be multiple first leak-proof grooves 75, which are spaced apart from top to bottom. The first leak-proof grooves 75 are arranged horizontally. The first leak-proof grooves 75 can increase the capacity for storing leaked liquid and prevent the leaked liquid from overflowing, making the electronic atomizer more convenient to use.

The plurality of second anti-leakage grooves 85 are sequentially arranged from top to bottom, and the second anti-leakage grooves 85 are arranged horizontally. The second anti-leakage grooves 85 can further increase the capacity for storing leaked liquid, prevent the leaked liquid from overflowing, and make the electronic atomizer more convenient to use.

[0050] See also Figure 2 In one embodiment, the electronic atomizer further includes a first seal 90, which is disposed inside the shell 10.

The protrusion 82 is connected to the first sealing component 90 via the locking protrusion 822. The protrusion 82 can support the first sealing component 90 to prevent the first sealing component 90 from shifting, thereby making the structural assembly of the electronic atomizer more convenient.
