[0015] FIG. 1 is a schematic diagram of an electronic atomization device provided in an embodiment of the present application.

[0016] 1, the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20. In some examples, the atomizer 10 and the power supply assembly 20 are non-detachable. In some examples, the atomizer 10 and the power supply assembly 20 are detachably connected, such as by an interference fit, a buckle connection, or a magnetic connection.

[0017] The atomizer 10 is used to heat and atomize a liquid substrate to produce an aerosol.

[0018] The power supply assembly 20 includes a battery cell 21 and circuitry 22 .

[0019] The battery cell 21 supplies power for operating the electronic atomization device 100. The battery cell 21 may be a rechargeable battery cell or a disposable battery cell.

[0020] The circuit 22 can control the overall operation of the electronic atomization device 100. The circuit 22 controls the operation of the battery cell 21 and the atomizer 10, as well as the operation of other components in the electronic atomization device 100.

[0021] 2 to 14 are schematic diagrams showing the structure of an atomizer according to an embodiment. In the atomizer 10 of the embodiment, The electronic atomization device 100 includes an external housing 101 having an opening 101a at its proximal end and an opening 101b at its distal end. The opening 101a may serve as an aerosol outlet. A user or inhaler can inhale the aerosol generated by the electronic atomization device 100 through the opening 101a. The external housing 101 includes an aerosol transport tube 101c and a liquid storage cavity 101d. One end of the aerosol transport tube 101c is connected to the opening 101a. The liquid storage cavity 101d for storing a liquid substrate is connected to the opening 101b, and the atomization assembly 102 and the seal member 103 can be assembled into the external housing 101 through the opening 101b. In a further embodiment, the internal surface of the external housing 101 further includes a positioning post (not shown), which can position the upstream end 103a of the seal member 103 when the seal member 103 is assembled into the external housing 101 through the opening 101b.

[0022] In some examples, at least a portion of the outer housing 101 is made of a transparent material, such as a transparent plastic, so that the internal components and the liquid substrate can be seen through the outer housing 101. For example, the receiving cavity 103d, the atomizing assembly 102, or the aerosol transport passage 103f can be seen through the opening 103c3.

[0023] The atomizing assembly 102 includes a liquid directing element 102a and a heating element 102b.

[0024] 6 and 7, in one example, the liquid guide element 102a is a rigid porous body, preferably a porous ceramic body. The liquid guide element 102a is generally block-shaped. The liquid guide element 102a includes a first portion 102a1 and a second portion 102a2 extending axially from the first portion 102a1. The dimension of the first part 102a1 in the length direction (X direction in FIG. 2) of the electronic atomization device 100 or the atomizer 10 is slightly larger than the dimension of the second part 102a2 in the length direction of the electronic atomization device 100, the dimension of the first part 102a1 in the thickness direction (Z direction in FIG. 2) of the electronic atomization device 100 or the atomizer 10 is slightly larger than the dimension of the second part 102a2 in the thickness direction of the electronic atomization device 100, and the dimension of the first part 102a1 in the width direction (Y direction in FIG. 2) of the electronic atomization device 100 or the atomizer 10 is the same as the dimension of the second part 102a2 in the width direction of the electronic atomization device 100.

[0025] The surface 102a11 of the first portion 102a1 defines a liquid absorption surface, and the surface 102a21 of the second portion 102a2 defines an atomization surface. The surfaces 102a11 and 102a21 are arranged opposite each other in the longitudinal direction of the electronic atomization device 100. The liquid guide element 102a transfers the liquid substrate from the liquid absorption surface to the atomization surface by capillary force. The porosity of the first portion 102a1 and the second portion 102a2 may be the same or different. In a preferred embodiment, the porosity of the first portion 102a1 is greater than the porosity of the second portion 102a2.

[0026] The heating element 102b is attached to or coupled to the atomizing surface and is used to heat and atomize the liquid substrate to generate an aerosol. The heating element 102b may be a resistive heating element and is formed on the atomizing surface by mounting, printing, deposition, or the like. The heating element 102b includes an electrical connection portion 102b1 and a heating circuit 102b2. There are two electrical connection portions 102b1, and the heating circuit 102b2 is disposed between the two electrical connection portions 102b1. The heating circuit 102b2 may be made of a material such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium metal. As shown in FIG. 7, the heating circuit 102b2 is a conductive trace patterned with a meander, circuit, or other shape. The electrical connection portion 102b1 may be a washer and may have a rectangular, circular, elliptical, or other shape.

[0027] 8 and 9, in another example, the liquid guide element 102a generally has a first side wall 102a1′ and a second side wall 102a2′ opposed to each other in the thickness direction, and a notch 102a3′ located between the first side wall 102a1′ and the second side wall 102a2′. The liquid guide element 102a further has the first side wall 102a1′ and / or the second side wall 102a2′ and / or the notch 102a3′ and / or an atomization surface 102a7′ opposite the liquid storage cavity 101d in the longitudinal direction.

[0028] The base portion 102a4' is located at the lower end of the liquid guide element 102a in the vertical direction and extends between the first side wall 102a1' and the second side wall 102a2'. The extension length of the base portion 102a4' in the longitudinal direction of the liquid guide element 102a is the same as the extension length of the first side wall 102a1' and / or the second side wall 102a2'. As shown in the figure, the lower surface of the base portion 102a4' is used as the atomizing surface 102a7'.

[0029] The connecting portion 102a5' is located on the upper end side of the liquid guide element 102a in the vertical direction and is arranged close to the center of the liquid guide element 102a. The connecting portion 102a5' similarly extends between the first side wall 102a1' and the second side wall 102a2'. The extending length of the connecting portion 102a5' in the longitudinal direction of the liquid guide element 102a is shorter than the extending length of the first side wall 102a1' and / or the second side wall 102a2' and / or the base portion 102a4'. Furthermore, the area not covered by the connecting portion 102a5' becomes a notch 102a3'.

[0030] Additionally, a longitudinally extending space 102a6' is defined between the connecting portion 102a5' and the base portion 102a4'. The space 102a6' can be used to receive or temporarily store the liquid substrate and to adjust the amount or efficiency of the liquid substrate supplied to the atomizing surface 102a7'.

[0031] The heating element 102b' is provided on the atomizing surface 102a7' of the liquid directing element 102a, and together they form an atomizing assembly, which heats and atomizes at least a portion of the liquid substrate in the liquid directing element 102a to generate an aerosol, which is then emitted by the atomizing surface 102a7'.

[0032] For ease of explanation, the following description will refer to the atomization assembly 102 shown in FIGS.

[0033] The sealing member 103 is made of a flexible material, such as silica gel, thermoplastic elastomer, or thermoplastic rubber, and is preferably made of a single material, such as thermoplastic elastomer.

[0034] As shown in Figures 10 to 12, the sealing member 103 includes an upstream end 103a (one end far from the liquid storage cavity 101d), a downstream end 103b (one end closer to the liquid storage cavity 101d), a main body 103c extending from the upstream end 103a to the downstream end 103b, a storage cavity 103d, a liquid transport passage 103e, an aerosol transport passage 103f, and a protruding arm 103g.

[0035] The upstream end 103a has an opening at its end face.

[0036] The end face of the downstream end 103b has an opening communicating with the liquid transport channel 103e, which serves as a liquid inlet through which the liquid substrate stored in the liquid storage cavity 101d can flow into the liquid transport channel 103e. The end face of the downstream end 103b also has an opening communicating with the aerosol transport channel 103f.

[0037] At least one flange 103c1 is provided on the outer surface of the main body 103c near the upstream end 103a, and at least one flange 103c2 is provided on the outer surface of the main body 103c near the downstream end 103b. Both flanges 103c1 and 103c2 are arranged to surround the outer periphery of the main body 103c, forming a convex ring. The number of flanges 103c1 is not limited, and multiple flanges 103c1 can be provided spaced apart on the outer surface of the main body 103c, with similar flanges 103c2. Both flanges 103c1 and 103c2 contact the inner surface of the outer housing 101 to provide a seal. In a preferred embodiment, four flanges 103c1 are provided on the outer surface of the main body 103c near the upstream end 103a, and the four flanges 103c1 are arranged in sequence in the length direction of the electronic atomization device 100 or the atomizer 10, with two of the flanges 103c1 being provided immediately adjacent to the upstream end 103a and the remaining two flanges 103c1 maintaining a fixed distance from the two flanges 103c1. Two to four flanges 103c2 are provided on the outer surface of the main body 103c near the downstream end 103b, and the flanges 103c2 are arranged in sequence in the length direction of the electronic atomization device 100 or the atomizer 10, with the flange 103c2 being provided immediately adjacent to the downstream end 103b.

[0038] An opening 103c3 is provided in at least one of the two opposing side walls of the main body 103c in the thickness direction of the electronic atomization device 100 or atomizer 10. In the length direction of the electronic atomization device 100 or atomizer 10, the opening 103c3 is provided between the flange 103c1 and the flange 103c2. The opening 103c3 penetrates the inner and outer surfaces of the main body 103c and communicates with both the containing cavity 103d and the aerosol transport passage 103f. The dimension of the opening 103c3 in the length direction of the electronic atomization device 100 or atomizer 10 is 5 mm to 7 mm, preferably 5 mm to 6 mm, and more preferably 5.5 mm to 6 mm. The dimension of the opening 103c3 in the width direction of the electronic atomization device 100 or the atomizer 10 is 3 mm to 5 mm, preferably 3 mm to 4.5 mm, and more preferably 3.5 mm to 4.5 mm.

[0039] A liquid retention area for retaining a portion of the liquid substrate from the receiving cavity 103d or the aerosol transport passage 103f is defined between the main body 103c, which is located between the flanges 103c1 and 103c2, and the outer housing 101. The liquid retention area includes a plurality of capillary grooves 103c4 distributed on the outer surface of the main body 103c, and the capillary grooves 103c4 extend at least partially along the outer periphery of the main body 103c. In a preferred embodiment, the capillary grooves 103c4 have one end communicating with the opening 103c3 and the other end extending along the outer periphery of the main body 103c and terminating at the opening 103c3. The number of capillary grooves 103c4 is not limited, and a plurality of spaced apart capillary grooves 103c4 can be provided on the outer surface of the main body 103c, and the plurality of spaced apart capillary grooves 103c4 can be connected to each other (for example, by providing a capillary groove extending in the length direction of the electronic atomization device 100 or the atomizer 10 on the outer surface of the main body 103c, the plurality of spaced apart capillary grooves 103c4 can be connected to each other). In a preferred embodiment, about 5 to 6 capillary grooves 103c4 are arranged in sequence in the length direction of the electronic atomization device 100 or the atomizer 10, and the capillary grooves 103c4 are spaced apart and do not communicate with each other, and the dimension of the capillary grooves 103c4 in the length direction of the electronic atomization device 100 or the atomizer 10 is 0.4 mm to 0.6 mm, and the distance between adjacent capillary grooves 103c4 is 0.4 mm to 0.6 mm. The distance between the capillary groove 103c4 and the flange 103c1 must be smaller than the distance between the capillary groove 103c4 and the flange 103c2, which is advantageous for the liquid substrate or condensate to be stored between the capillary groove 103c4 and the flange 103c2.

[0040] A partition wall 103c5 is further provided within the main body 103c. The storage cavity 103d and the aerosol transport passage 103f are separated by the partition wall 103c5 in the longitudinal direction of the electronic atomization device 100 or the atomizer 10. The partition wall 103c5 has a substantially V-shaped surface on the side facing the aerosol transport passage 103f, which is advantageous for collecting condensed liquid in the aerosol transport passage 103f and guiding it into the storage cavity 103d for reabsorption by the liquid guiding element 102a.

[0041] The accommodating cavity 103d is provided within the main body 103c. The accommodating cavity 103d is in communication with the opening of the upstream end 103a, and the atomizing assembly 102 can be assembled into the accommodating cavity 103d through the opening of the upstream end 103a. The liquid-absorbing surface of the atomizing assembly 102 faces the liquid storage cavity 101d, and the atomizing surface of the atomizing assembly 102 faces the opening of the upstream end 103a. At least a portion of the space between the atomizing surface and the opening of the upstream end 103a forms the atomizing cavity A. When the atomizing assembly 102 is assembled into the accommodating cavity 103d through the opening of the upstream end 103a, part of the boundary of the atomizing cavity A or the aerosol transport passage 103f is defined by the inner surface of the outer housing 101. In this manner, the boundary of the atomizing cavity A or the aerosol transport passage 103f is significantly enlarged, which is advantageous for reducing the generation of condensation.

[0042] The two outer surfaces (left and right side walls) of the liquid guide element 102a that face each other in the width direction of the electronic atomization device 100 are in contact with or elastically abut against the partial inner surface 103c6 of the main body 103c, and parts of the two outer surfaces (front and rear side walls) that face each other in the thickness direction of the electronic atomization device 100 of the first part 102a1 of the liquid guide element 102a are in contact with or elastically abut against the partial inner surface 103c7 of the main body 103c. This provides a seal on at least a part of the outer surface of the liquid guide element 102a.

[0043] In some embodiments, the two outer surfaces (left and right outer surfaces) of the liquid guide element 102a that face each other in the width direction of the electronic atomization device 100 or the atomizer 10 are in contact with or elastically abut on the two partial inner surfaces 103c6 of the main body 103c that face each other in the width direction of the electronic atomization device 100 or the atomizer 10 in a one-to-one correspondence. The one-to-one correspondence means that the left side wall of the liquid guide element 102a is in contact with or elastically abuts on the left partial inner surface 103c6 of the main body 103c, and the right side wall of the liquid guide element 102a is in contact with or elastically abuts on the right partial inner surface 103c6 of the main body 103c. Parts of the two outer surfaces (front and rear surfaces) of the first part 102a1 of the liquid guide element 102a, which face each other in the thickness direction of the electronic atomization device 100 or the atomizer 10, are in contact or elastic abutment with two partial inner surfaces 103c7 of the main body 103c, which face each other in the thickness direction of the electronic atomization device 100 or the atomizer 10. This provides a seal on at least a part of the outer surface of the liquid guide element 102a. The partial inner surfaces 103c6 and 103c7 each define part of the boundary of the containing cavity 103d.

[0044] In a further embodiment, the width dimension of the liquid guide element 102a of the electronic atomization device 100 or the atomizer 10 is slightly larger than the distance between the two partial inner surfaces 103c6 of the main body 103c (or the width dimension of the electronic atomization device 100 or the atomizer 10 of the receiving cavity 103d), and the thickness dimension of the first part 102a1 of the electronic atomization device 100 or the atomizer 10 is slightly larger than the distance between the two partial inner surfaces 103c7 of the main body 103c (or the thickness dimension of the electronic atomization device 100 or the atomizer 10 of the receiving cavity 103d), thereby improving the interference fit between the sealing member 103 and the liquid guide element 102a.

[0045] The liquid absorption surface of the atomization assembly 102 and the surface 103c51 of the partition wall 103c5 facing the liquid absorption surface may be in contact or elastic abutment in the longitudinal direction of the electronic atomization device 100 or the atomizer 10, and the surface 103c51 of the partition wall 103c5 is further provided with a groove 103c52, which extends in the width direction of the electronic atomization device 100 or the atomizer 10.

[0046] It should be noted that in other examples, the liquid absorbing surface of the atomizing assembly 102 and the surface 103c51 of the partition wall 103c5 may not be in contact with each other along the length of the electronic atomizing device 100 or the atomizer 10.

[0047] It should be noted that in the example nebulization assembly 102 shown in Figures 8 and 9, the partition wall 103c5 may not be provided, and the end face of the lower end of the aerosol transport passage 103f may be in contact with or elastically abut against the connection portion 102a5'.

[0048] The two outer surfaces of the second portion 102a2 of the liquid guide element 102a, which face each other in the thickness direction of the electronic atomization device 100, are spaced apart from the inner surface of the main body 103c, thereby preventing heat loss from the heating element 102b.

[0049] In some embodiments, the two outer surfaces (front and rear surfaces) of the liquid guide element 102a, which face each other in the thickness direction of the electronic atomization device 100 or the atomizer 10, are spaced apart in a one-to-one correspondence with the two partial inner surfaces 103c8 of the main body 103c, which face each other in the thickness direction of the electronic atomization device 100 or the atomizer 10. The partial inner surfaces 103c8 define part of the boundary of the containing cavity 103d. Because the heating element 102b is located in the second portion 102a2, the temperature of the second portion 102a2 is too high (the closer to the atomization surface, the higher the temperature). By spaced apart in a one-to-one correspondence with the second portion 102a2 of the liquid guide element 102a, the problem of excessive heat being conducted to the sealing member 103, which may cause the sealing member 103 to be easily deformed, can be avoided, while heat loss from the heating element 102b can be reduced.

[0050] In some alternative embodiments, as shown in FIG. 13, when the liquid guide element 102a is accommodated in the accommodation cavity 103d, the two outer surfaces (front and rear surfaces) of the liquid guide element 102a and the two partial inner surfaces 103c8 of the main body 103c are spaced apart in a one-to-one correspondence. This forms a plurality of grooves B for storing a portion of the liquid substrate between the outer surface of the liquid guide element 102a and the partial inner surface 103c8 of the main body 103c. The grooves B are recessed toward the liquid storage cavity 101d and are adjacent to the surface 103c51 of the partition wall 103c5. The grooves B are adjacent to the atomization surface of the liquid guide element 102a. For example, referring to FIG. 13, there are four grooves B, distributed at the four corners near the atomization surface of the liquid guide element 102a. The grooves B do not directly communicate with the liquid storage cavity 101d and are separated by the liquid guide element 102a. The width of the groove B (the dimension in the thickness direction of the electronic atomization device 100 or the atomizer 10) is 0.4 mm to 0.6 mm, and may be 0.45 mm, 0.5 mm, 0.55 mm, etc. for example. The length of the groove B (the dimension in the width direction of the electronic atomization device 100 or the atomizer 10) is 0.8 mm to 1.5 mm, and may be 1 mm, 1.2 mm, 1.4 mm, etc. for example. The depth of the groove B (the dimension in the length direction of the electronic atomization device 100 or the atomizer 10) is 1 mm to 2 mm, and may be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, etc. for example. The groove B can be used to store the liquid substrate or condensate exuded from the liquid guiding element 102a, which effectively reduces liquid leakage and improves the inhalation experience. When the atomizing assembly 102 starts heating, the liquid substrate or condensate stored in the groove B can be sucked by the liquid guiding element 102a and heated and atomized by the heating element 102b. The groove B is adjacent to the atomizing surface of the liquid guiding element 102a, which is advantageous for quickly replenishing the liquid substrate with the heating element 102b. Furthermore, if there is too much liquid substrate or condensate stored in the groove B, it can be guided into the collecting cavity 104d of the bottom cover 104 via the guide groove 103g1.

[0051] In another embodiment, the recessed groove B and the capillary groove 103c4 can communicate with each other, for example, they communicate with each other through the capillary groove 103c9 formed in the opening 103c3, which essentially extends in the thickness direction of the electronic atomization device 100 or the atomizer 10, with one end fluidly communicating with the recessed groove B and the other end fluidly communicating with the capillary groove 103c4. In this way, the liquid substrate or condensate stored in the capillary groove 103c4 can flow into the recessed groove B along the capillary groove 103c9 formed in the opening 103c3.

[0052] The liquid transport passage 103e is provided in the main body 103c. One end of the liquid transport passage 103e is connected to the opening on the end face of the downstream end 103b, and the other end is connected to the receiving cavity 103d. In a preferred embodiment, the two liquid transport passages 103e are provided symmetrically in the main body 103c in the width direction of the electronic atomization device 100 or the atomizer 10, and can be connected via the groove 103c52 in the partition wall 103c5. In this way, the contact area between the liquid substrate and the liquid guiding element 102a is increased, and the liquid substrate can be guided more smoothly to the liquid guiding element 102a.

[0053] The aerosol transport passage 103f is provided in the main body 103c. One end of the aerosol transport passage 103f communicates with an opening on the end face of the downstream end 103b, and the other end communicates with the storage cavity 103d via an opening 103c3. The aerosol transport passage 103f is used to transport the aerosol generated by atomization by the atomization assembly 102.

[0054] After assembly, the other end of aerosol transport pipe 101c is inserted into aerosol transport passage 103f through the opening at the end face of downstream end 103b, and sealing member 103 seals aerosol transport pipe 101c.

[0055] In a further implementation, a stopper 103f1 is further provided within the aerosol transport passage 103f to stop the other end of the aerosol transport tube 101c. The stopper 103f1 comprises a bump provided on the inner surface of the aerosol transport passage 103f.

[0056] In a further implementation, the stopper portion 103f1 is further provided with a guide groove 103f11, which allows the condensed liquid in the aerosol transport tube 101c to be better guided to the atomization assembly 102 instead of accumulating on the partition wall 103c5.

[0057] The liquid storage cavity 101d is defined by the inner surface of the outer housing 101, the outer surface of the aerosol transport tube 101c, and the end face of the downstream end 103b of the seal member 103. The liquid substrate stored in the liquid storage cavity 101d can be transported to the nebulizing assembly 102 via a liquid transport passage 103e (as shown by R1 in FIG. 4).

[0058] In another embodiment, a capillary groove 103e1 is provided in the liquid transport passage 103e, with one end of the capillary groove 103e1 communicating with an opening on the end face of the downstream end 103b and the other end extending to the partial inner surface 103c6 of the main body 103c and communicating with the storage cavity 103d. The capillary groove 103e1 is advantageous in guiding air masses or bubbles from the outside or the atomization cavity A into the liquid storage cavity 101d, allowing the liquid substrate to smoothly pass through the liquid transport passage 103e. The width of the capillary groove 103e1 is 0.4mm to 0.6mm. The number of capillary grooves 103e1 is not limited, and in a preferred embodiment, three to six capillary grooves 103e1 are provided in the liquid transport passage 103e, and the capillary grooves 103e1 are spaced apart from one another.

[0059] The protruding arm 103g extends from the inner surface of the main body 103c toward the opening at the upstream end 103a.

[0060] The bottom cover 104 is removably coupled to the opening 101b at the distal end of the outer housing 101, and further defines the housing of the atomizer together with the outer housing 101. In a preferred embodiment, the bottom cover 104 and the outer housing 101 are connected by a buckle.

[0061] 14 , the bottom cover 104 is provided with a first electrode hole 104a and a second electrode hole 104b, and first electrodes 105 and second electrodes 106 are attached in a one-to-one correspondence. One end of the first electrode 105 contacts one electrical connection portion 102b1 of the heating element 102b to form an electrical connection, and the other end of the first electrode 105 is exposed to the bottom cover 104. One end of the second electrode 106 contacts another electrical connection portion 102b1 of the heating element 102b to form an electrical connection, and the other end of the second electrode 106 is exposed to the bottom cover 104. Furthermore, the first electrode 105 and the second electrode 106 can further support the atomizing assembly 102 so that the atomizing assembly 102 is held within the seal member 103.

[0062] 3 to 7, both the first electrode 105 and the second electrode 106 are inelastic electrodes. When assembling the first electrode 105 and the second electrode 106 to the atomizer 10, the first electrode 105 and the second electrode 106 are supported by the bottom cover 104 and extend linearly toward the atomizing assembly 102. The liquid-absorbing surface of the atomizing assembly 102 contacts or elastically abuts against the surface 103c51 of the partition wall 103c5, so that the sealing member 103 is elastically compressed. Furthermore, the atomizing assembly 102 can apply an elastic force to the first electrode 105 or the second electrode 106 downward or in the direction opposite to the assembly direction, so that one end of the first electrode 105 or the second electrode 106 maintains good contact with the electrical connection portion 102b1 of the heating element 102b and is less likely to shift position.

[0063] In an alternative embodiment, the first electrode 105 or the second electrode 106 can be replaced with an electrode shown in FIG. 15. As shown in FIG. 15, the electrode includes a first end 105a, a second end 105b opposite the first end 105a, and a flange 105c provided between the first end 105a and the second end 105b. The end surface of the first end 105a contacts the electrical connection portion 102b1 of the heating element 102b to form an electrical connection, and the end surface of the second end 105b is exposed to the bottom cover 104. During assembly, the first electrode hole 104a or the second electrode hole 104b receives the flange 105c.

[0064] Some of the electrodes located between the first end 105a and the flange 105c have a small cross section and a long length, while some of the electrodes located between the flange 105c and the second end 105b have a large cross section and a short length, thereby reducing the heat transfer from the heating element 102b from the first end 105a to the second end 105b.

[0065] The bottom cover 104 further includes an air inlet 104c. Referring again to FIG. 5, external air enters the atomizer 10 through the air inlet 104c. The aerosol generated by the heating element 102b heating and atomizing the liquid substrate is mixed with the air and passes through the opening 103c3 to collect in the aerosol transport passage 103f. The aerosol then passes through the aerosol transport pipe 101c and flows out through the opening 101a (see R2 in the figure). As can be seen from the figure, the opening 103c3 is located between the flange 103c1 and the flange 103c2, both of which contact the inner surface of the outer housing 101 to form a seal. This ensures that the airflow passes through the opening 103c3 and flows into the aerosol transport passage 103f.

[0066] The bottom cover 104 further has a collection cavity 104d, and the first electrode hole 104a, the second electrode hole 104b, and the air intake 104c all protrude from the collection cavity 104d, which is used to collect the liquid substrate and prevent the liquid substrate from flowing into the power supply assembly 20.

[0067] The outer surface of the bottom cover 104 has steps 104e and 104f. After assembly, a portion of the side wall of the bottom cover 104 is sandwiched between the protruding arm 103g of the sealing member 103 and the inner surface of the outer housing 101, with the end face of the upstream end 103a abutting against the step 104e and the end face of the distal end of the outer housing 101 abutting against the step 104f. In a further embodiment, the protruding arm 103g is further provided with a guide groove 103g1, which is used to better guide the liquid substrate or condensate into the collection cavity 104d of the bottom cover 104 to prevent the liquid substrate from flowing into the power supply assembly 20.

[0068] 12, an airflow groove 103c61 is provided on the partial inner surface 103c6 of the main body 103c, and the airflow groove 103c61 extends along the inner surface 103c6 of the main body 103c and terminates at the liquid transport passage 103e, defining an air pressure balance passage. One end of the airflow groove 103c61 communicates with the atomization cavity A, and the other end communicates with the liquid transport passage 103e. Due to the presence of the air flow groove 103c61, when the nebulizing assembly 102 is assembled into the accommodating cavity 103d through the opening at the upstream end 103a, there is a small gap between the nebulizing assembly 102 and the partial inner surface 103c6 of the main body 103c, and air that enters the nebulizing cavity A can pass through the air flow groove 103c61 and flow into the liquid storage cavity 101d, thereby relieving the negative pressure in the liquid storage cavity 101d.

[0069] In some examples, the air pressure balance passage may be defined by an airflow groove provided in the partial inner surface 103c7 of the main body 103c.

[0070] In some examples, the airflow grooves may be provided on two outer surfaces (or one of the outer surfaces) of the liquid guiding element 102a that face each other in the width direction or thickness direction of the electronic atomization device 100 or the atomizer 10.

[0071] In some examples, the air pressure balance passage may be defined by a through hole (not shown) provided in the partition wall 103c5, one end of which is connected to the aerosol transport passage 103f and the other end of which is connected to the liquid transport passage 103e or the recessed groove 103c52 in the partition wall 103c5.

[0072] It should be noted that although the specification and drawings of this application show preferred embodiments of the present application, the present application can be realized in many different forms and is not limited to the embodiments described herein. These embodiments do not further limit the content of the present application, and the purpose of providing these embodiments is to make the disclosure of this application more complete and comprehensive.
