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

[0016] As shown in Figure 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 cannot be disassembled. In some examples, the atomizer 10 and the power supply assembly 20 are detachably connected, such as by interference fit, buckle connection or magnetic connection.

[0017] The atomizer 10 is used for heating and atomizing a liquid substrate to generate an aerosol.

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

[0019] The battery cell 21 supplies electric 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 not only the operations of the battery cell 21 and the atomizer 10, but also the operations of other components in the electronic atomization device 100.

[0021] Figures 2 to 14 are schematic structural diagrams of an atomizer according to one embodiment. In the atomizer 10 of this embodiment, The external housing 101 includes 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 atomizer 100 through the opening 101a. Inside the external housing 101 are an aerosol transport pipe 101c and a liquid storage cavity 101d. One end of the aerosol transport pipe 101c communicates with the opening 101a. The liquid storage cavity 101d for storing a liquid substrate communicates with the opening 101b, and the atomization assembly 102 and the sealing member 103 can be assembled inside the external housing 101 through the opening 101b. In a further embodiment, the inner surface of the external housing 101 may further include a positioning column (not shown) that can position the upstream end 103a of the sealing member 103 when the sealing member 103 is assembled inside 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 transparent plastic, so that the internal components and liquid substrate can be seen through the outer housing 101. For example, the containment cavity 103d, atomization assembly 102, or aerosol transport passage 103f can be seen through the opening 103c3.

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

[0024] As shown in Figures 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 substantially 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 dimensions of the electron atomizer 100 or atomizer 10 of the first part 102a1 in the longitudinal direction (X direction in Figure 2) are slightly larger than the dimensions of the electron atomizer 100 of the second part 102a2 in the longitudinal direction, the dimensions of the electron atomizer 100 or atomizer 10 of the first part 102a1 in the thickness direction (Z direction in Figure 2) are slightly larger than the dimensions of the electron atomizer 100 of the second part 102a2 in the thickness direction, and the dimensions of the electron atomizer 100 or atomizer 10 of the first part 102a1 in the width direction (Y direction in Figure 2) are the same as the dimensions of the electron atomizer 100 of the second part 102a2 in the width direction.

[0025] The surface 102a11 of the first portion 102a1 defines the liquid absorption surface, and the surface 102a21 of the second portion 102a2 defines the atomization surface. Surfaces 102a11 and 102a21 are arranged opposite each other in the longitudinal direction of the electronic atomizer 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 that of the second portion 102a2.

[0026] The heating element 102b is provided on or bonded to the atomizing surface and is used to heat and atomize a liquid substrate to generate an aerosol. The heating element 102b may be resistive heating and may be formed on the atomizing surface by mounting, printing, deposition, etc. The heating element 102b includes an electrical connection part 102b1 and a heating circuit 102b2. There are two electrical connection parts 102b1, and the heating circuit 102b2 is provided between the two electrical connection parts 102b1. The heating circuit 102b2 may be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or metallic titanium. As shown in Figure 7, the heating circuit 102b2 is a patterned conductive trajectory such as a meandering or bypassing path. The electrical connection part 102b1 may be a washer and may have a shape such as a square, circle, or ellipse.

[0027] As shown in Figures 8 to 9, in another example, the liquid guide element 102a as a whole has a first side wall 102a1' and a second side wall 102a2' that are opposite 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 an atomizing surface 102a7' opposite in the longitudinal direction to the first side wall 102a1' and / or the second side wall 102a2' and / or the notch 102a3' and / or the liquid storage cavity 101d.

[0028] The base portion 102a4' is located on the lower vertical end side of the liquid guide element 102a and extends between the first side wall 102a1' and the second side wall 102a2'. The length of the base portion 102a4' extending along the length of the liquid guide element 102a is the same as the 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 vertical end side of the liquid guide element 102a and is positioned 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'. Furthermore, the length of the connecting portion 102a5' extending in the longitudinal direction of the liquid guide element 102a is smaller than the length of the first side wall 102a1' and / or the second side wall 102a2' and / or the base portion 102a4'. In addition, the area not covered by the connecting portion 102a5' becomes a notch 102a3'.

[0030] Furthermore, a space 102a6' extending in the longitudinal direction 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 further 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 guide element 102a, and together they form an atomizing assembly. The heating element heats and atomizes at least a portion of the liquid substrate in the liquid guide element 102a to generate an aerosol, which is then released by the atomizing surface 102a7'.

[0032] For the sake of clarity, the following description will refer to the atomizing assembly 102 shown in Figures 6 and 7.

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

[0034] As shown in Figures 10 to 12, the sealing member 103 includes an upstream end 103a (one end farther 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] There is an opening at the end face of the upstream end 103a.

[0036] The end face of the downstream end 103b has an opening that communicates with the liquid transport passage 103e, which is used as a liquid inlet, and the liquid substrate stored in the liquid storage cavity 101d can flow into the liquid transport passage 103e through this opening. The end face of the downstream end 103b also has an opening that communicates with the aerosol transport passage 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 circumference of the main body 103c, forming a convex ring. The number of flanges 103c1 is not limited, and multiple spaced flanges 103c1 can be provided on the outer surface of the main body 103c, and the same applies to flanges 103c2. Both flanges 103c1 and 103c2 contact the inner surface of the outer housing 101 to achieve 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 sequentially along the length of the electronic atomizer 100 or atomizer 10, with two of the flanges 103c1 located immediately adjacent to the upstream end 103a and the remaining two flanges 103c1 maintaining a certain distance from these 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 sequentially along the length of the electronic atomizer 100 or atomizer 10, with the flanges 103c2 located immediately adjacent to the downstream end 103b.

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

[0039] Between the main body 103c, located between flanges 103c1 and 103c2, and the outer housing 101, a liquid-holding region is defined for holding a portion of the liquid substrate from the containment cavity 103d or the aerosol transport passage 103f. The liquid-holding region includes a plurality of capillary grooves 103c4 distributed on the outer surface of the main body 103c, the capillary grooves 103c4 extending at least partially along the outer circumference of the main body 103c. In a preferred embodiment, one end of the capillary grooves 103c4 communicates with an opening 103c3, and the other end extends along the outer circumference of the main body 103c and terminates at the opening 103c3. The number of capillary grooves 103c4 is not limited, and multiple spaced-apart capillary grooves 103c4 can be provided on the outer surface of the main body 103c, and multiple spaced-apart capillary grooves 103c4 can communicate with each other (for example, by providing capillary grooves extending in the longitudinal direction of the electronic atomizer 100 or atomizer 10 on the outer surface of the main body 103c, multiple spaced-apart capillary grooves 103c4 can communicate with each other). In a preferred embodiment, approximately 5 to 6 capillary grooves 103c4 are arranged sequentially in the longitudinal direction of the electronic atomizer 100 or atomizer 10, the capillary grooves 103c4 are spaced apart and do not communicate with each other, the dimensions of the capillary grooves 103c4 in the longitudinal direction of the electronic atomizer 100 or atomizer 10 are 0.4 mm to 0.6 mm, and the spacing 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 storage of a liquid substrate or condensate between the capillary groove 103c4 and the flange 103c2.

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

[0041] The containment cavity 103d is located within the main body 103c. The containment cavity 103d communicates with the opening at the upstream end 103a, and the atomizing assembly 102 can be assembled within the containment cavity 103d via the opening at the upstream end 103a. The liquid absorption surface of the atomizing assembly 102 faces the liquid storage cavity 101d, and the atomizing surface of the atomizing assembly 102 faces the opening at the upstream end 103a. At least a portion of the space between the atomizing surface and the opening at the upstream end 103a becomes the atomizing cavity A. When the atomizing assembly 102 is assembled within the containment cavity 103d via the opening at the upstream end 103a, a portion 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 way, the boundary of the atomizing cavity A or the aerosol transport passage 103f is significantly enlarged, which is advantageous in reducing the generation of condensate.

[0042] Two opposing outer surfaces (left and right side walls) of the liquid guide element 102a in the width direction of the electronic atomizer 100 are in contact with or elastically abut against the partial inner surface 103c6 of the main body 103c, and parts of two opposing outer surfaces (front and rear side walls) of the first part 102a1 of the liquid guide element 102a in the thickness direction of the electronic atomizer 100 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 portion 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 are opposite each other in the width direction of the electronic atomizer 100 or atomizer 10 are in contact with or elastically abutting two opposing partial inner surfaces 103c6 of the main body 103c that are opposite each other in the width direction of the electronic atomizer 100 or atomizer 10 in a one-to-one correspondence. One-to-one correspondence means that the left wall of the liquid guide element 102a is in contact with or elastically abutting the left partial inner surface 103c6 of the main body 103c, and the right wall of the liquid guide element 102a is in contact with or elastically abutting the right partial inner surface 103c6 of the main body 103c. Parts of two opposing outer surfaces (front and rear surfaces) of the first portion 102a1 of the liquid guide element 102a in the thickness direction of the electronic atomizer 100 or atomizer 10 are in one-to-one contact or elastic abutment with two opposing inner surfaces 103c7 of the main body 103c in the thickness direction of the electronic atomizer 100 or atomizer 10. This provides a seal to at least a portion of the outer surface of the liquid guide element 102a. The inner surfaces 103c6 and 103c7 each define part of the boundary of the housing cavity 103d.

[0044] In further implementation, the widthwise dimension of the liquid guide element 102a in the electronic atomizer 100 or atomizer 10 is slightly larger than the distance between the two inner surfaces 103c6 of the main body 103c (or the widthwise dimension of the housing cavity 103d in the electronic atomizer 100 or atomizer 10), and the thicknesswise dimension of the first part 102a1 in the electronic atomizer 100 or atomizer 10 is slightly larger than the distance between the two inner surfaces 103c7 of the main body 103c (or the thicknesswise dimension of the housing cavity 103d in the electronic atomizer 100 or atomizer 10), thereby improving the tight fit between the sealing member 103 and the liquid guide element 102a.

[0045] The liquid-absorbing surface of the atomizing assembly 102 and the surface 103c51 of the partition wall 103c5 facing the liquid-absorbing surface may be in contact or elastically abutting in the longitudinal direction of the electronic atomizing device 100 or atomizer 10. The surface 103c51 of the partition wall 103c5 is further provided with a groove 103c52, which extends in the width direction of the electronic atomizing device 100 or 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 do not necessarily have to be in contact along the length of the electronic atomizer 100 or atomizer 10.

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

[0048] The two opposing outer surfaces of the second portion 102a2 of the liquid guide element 102a in the thickness direction of the electron atomizer 100 are spaced apart from the inner surface of the main body 103c. In this way, heat loss of the heating element 102b can be avoided.

[0049] In some embodiments, the two opposing outer surfaces (front and rear surfaces) of the liquid guide element 102a in the thickness direction of the electronic atomizer 100 or atomizer 10 are spaced apart in a one-to-one correspondence with the two opposing partial inner surfaces 103c8 of the main body 103c in the thickness direction of the electronic atomizer 100 or atomizer 10. The partial inner surfaces 103c8 define a part of the boundary of the housing cavity 103d. Since the heating element 102b is provided in the second portion 102a2, the temperature of the second portion 102a2 is too high (the temperature increases as you get closer to the atomizing surface). By spaced apart in a one-to-one correspondence between the second portion 102a2 of the liquid guide element 102a and the two partial inner surfaces 103c8 of the main body 103c, it is possible to avoid the problem of excessive heat being conducted to the sealing member 103, which would cause the sealing member 103 to deform easily, while also reducing the heat loss of the heating element 102b.

[0050] In some selective embodiments, as shown in Figure 13, when the liquid guide element 102a is housed in the containment 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. As a result, multiple grooves B for storing a portion of the liquid substrate are formed between the outer surface of the liquid guide element 102a and the partial inner surfaces 103c8 of the main body 103c. The grooves B are recessed toward the liquid storage cavity 101d and are close to the surface 103c51 of the partition wall 103c5. The grooves B are adjacent to the atomizing surface of the liquid guide element 102a. For example, referring to Figure 13, there are four grooves B, distributed in the four corners close to the atomizing surface of the liquid guide element 102a. The grooves B and the liquid storage cavity 101d are not in direct communication and are separated by the liquid guide element 102a. The width dimension of groove B (dimension in the thickness direction of the electronic atomizer 100 or atomizer 10) is 0.4 mm to 0.6 mm, and in specific examples, it may be 0.45 mm, 0.5 mm, 0.55 mm, etc. The length dimension of groove B (dimension in the width direction of the electronic atomizer 100 or atomizer 10) is 0.8 mm to 1.5 mm, and in specific examples, it may be 1 mm, 1.2 mm, 1.4 mm, etc. The depth dimension of groove B (dimension in the length direction of the electronic atomizer 100 or atomizer 10) is 1 mm to 2 mm, and in specific examples, it may be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, etc. The groove B described above can be used to store liquid substrate or condensate seeping from the liquid guide element 102a, and liquid leakage and suction experience are effectively improved. When the atomizing assembly 102 begins heating, the liquid substrate or condensate stored in groove B can be drawn in by the liquid guide element 102a and heated and atomized by the heating element 102b. Groove B is adjacent to the atomizing surface of the liquid guide element 102a, which is advantageous for rapidly replenishing the liquid substrate with the heating element 102b. Furthermore, if there is too much liquid substrate or condensate stored in groove B, it can be guided into the collection cavity 104d of the bottom cover 104 via the guide groove 103g1.

[0051] In further implementation, the groove B and the capillary groove 103c4 can communicate with each other, for example, via a capillary groove 103c9 formed in the opening 103c3, the capillary groove 103c9 formed in the opening 103c3 basically extends in the thickness direction of the electron atomizer 100 or atomizer 10, with one end fluidically communicating with the 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 groove B along the capillary groove 103c9 formed in the opening 103c3.

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

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

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

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

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

[0057] The liquid storage cavity 101d is defined and formed 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 sealing member 103. The liquid substrate stored in the liquid storage cavity 101d can be transported to the atomization assembly 102 via the liquid transport passage 103e (as shown in R1 in Figure 4).

[0058] In a further embodiment, a capillary groove 103e1 is provided within the liquid transport passage 103e, with one end communicating with an opening at the end face of the downstream end 103b and the other end extending to a partial inner surface 103c6 of the main body 103c and communicating with the containment cavity 103d. The capillary groove 103e1 is advantageous for guiding air masses or bubbles from the outside or atomization cavity A into the liquid storage cavity 101d, allowing the liquid substrate to pass smoothly through the liquid transport passage 103e. The width of the capillary groove 103e1 is 0.4 mm to 0.6 mm. The number of capillary grooves 103e1 is not limited, and in a preferred embodiment, 3 to 6 capillary grooves 103e1 are provided within the liquid transport passage 103e, spaced apart from each other.

[0059] The protruding arm 103g extends from the inner surface of the main body 103c toward the opening of 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 together with the outer housing 101, defines the housing of the atomizer. In a preferred embodiment, the bottom cover 104 and the outer housing 101 are connected by a buckle.

[0061] As shown in Figure 14, the bottom cover 104 is provided with a first electrode hole 104a and a second electrode hole 104b, and the first electrode 105 and the second electrode 106 are mounted 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 sealing member 103.

[0062] In the examples shown in Figures 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 into 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. Since the liquid-absorbing surface of the atomizing assembly 102 is in contact with or elastically abutting the surface 103c51 of the partition wall 103c5, the sealing member 103 is elastically compressed. Furthermore, the atomizing assembly 102 can apply an elastic force downward or opposite to the assembly direction to the first electrode 105 or the second electrode 106, thereby maintaining good contact with the electrical connection portion 102b1 of the heating element 102b and preventing misalignment.

[0063] In an alternative embodiment, the first electrode 105 or the second electrode 106 can be replaced with the electrode shown in Figure 15. As shown in Figure 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 face of the first end 105a contacts the electrical connection portion 102b1 of the heating element 102b to form an electrical connection, and the end face 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 secures the flange 105c.

[0064] Some electrodes located between the first end 105a and the flange 105c have a small cross-section and are long, while some electrodes located between the flange 105c and the second end 105b have a large cross-section and are short. In this way, the transfer of heat from the heating element 102b from the first end 105a to the second end 105b can be reduced.

[0065] The bottom cover 104 is further provided with an air intake port 104c. Referring further to Figure 5, outside air enters the atomizer 10 through the air intake port 104c, and the aerosol generated by heating the liquid substrate by the heating element 102b is mixed with the air, then passes through the opening 103c3 and collects in the aerosol transport passage 103f, and then passes through the aerosol transport pipe 101c and flows out from the opening 101a (see R2 in the figure). As can be seen from the figure, the opening 103c3 is provided between flange 103c1 and flange 103c2, and both flange 103c1 and flange 103c2 are in contact with the inner surface of the outer housing 101 to achieve a seal. In this way, it is possible to ensure that the airflow passes through the opening 103c3 and flows into the aerosol transport passage 103f.

[0066] The bottom cover 104 is further provided with a collection cavity 104d, the first electrode hole 104a, the second electrode hole 104b, and the intake port 104c all protrude from the collection cavity 104d, and the collection cavity 104d 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 in contact with step 104e and the end face of the distal end of the outer housing 101 in contact with step 104f. In a further implementation, 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 and prevent the liquid substrate from flowing into the power supply assembly 20.

[0068] Referring further to Figure 12, an airflow groove 103c61 is provided on the inner surface 103c6 of the main body 103c. The airflow groove 103c61 extends along the inner surface 103c6 of the main body 103c and terminates at the liquid transport passage 103e, thus defining and forming a 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 airflow groove 103c61, when the atomizing assembly 102 is assembled in the containment cavity 103d through the opening at the upstream end 103a, there is a small gap between the atomizing assembly 102 and the partial inner surface 103c6 of the main body 103c. Air entering the atomizing cavity A can pass through the airflow 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 pressure balance passage may be defined by an airflow groove provided on the partial inner surface 103c7 of the main body 103c.

[0070] In some examples, the airflow grooves may be provided on two opposing outer surfaces (or one of the outer surfaces) of the liquid guide element 102a in the width direction or thickness direction of the electronic atomizer 100 or atomizer 10.

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