[0080] Figures 1 and 2 show schematic diagrams of an electronic atomization device 100 according to one embodiment, including several components disposed within an outer body or housing (which may be referred to as a shell). The overall design of the outer body or housing may vary, and the type or configuration of the outer body that may define the overall size and shape of the electronic atomization device 100 may vary.

[0090] A liquid storage chamber 112 for storing a liquid matrix, and an atomizing assembly for drawing the liquid matrix from the liquid storage chamber 112 and heating and atomizing the liquid matrix. To facilitate vaporization and output, the liquid storage chamber 112 and the atomizing assembly are both arranged near the proximal end 110. The electronic atomizing device 100 also includes an aerosol output tube 111 arranged in the longitudinal direction, which at least partially extends within the liquid storage chamber 112, and the liquid storage chamber 112 is formed by the space between the outer wall of the aerosol output tube 111 and the inner wall of the housing 10. The end of the aerosol output tube 111 relative to the proximal end 110 is connected to the air outlet 113 to output the aerosol generated by atomization of the atomizing assembly to the air outlet 113 for inhalation.

[0091] According to the embodiment shown in FIG3 , the atomizing assembly for atomizing the liquid matrix includes:

[0092] The liquid-conducting element 13 is made of a capillary material or a porous material, such as a sponge, cotton fiber, or a porous body such as a porous ceramic body.

[0096] As shown in FIG3 , the housing 10 is further provided with:

[0097] The upper support element 15 and the lower support element 16 are positioned longitudinally on either side of the liquid-guiding element 13, thereby clamping and supporting the liquid-guiding element 13 from the upper and lower sides, respectively. After assembly, the liquid-guiding element 13 is supported and clamped between the upper support element 15 and the lower support element 16. A liquid channel 151 is arranged on the upper support element 15. During use, the liquid matrix in the liquid storage chamber 112 passes through the liquid channel 151 of the upper support element 15 and is delivered to the liquid-guiding element 13, as indicated by arrow R1 in Figure 3. A cavity surrounding the liquid-guiding element 13 and / or the heating element 14 is also defined between the upper support element 15 and the lower support element 16. This cavity serves as an atomization chamber, allowing the aerosol generated by heating by the heating element 14 to be released.

[0098] As shown in FIG3 , the housing 10 is further provided with:

[0099] A flexible sealing element 17 is arranged between the first housing portion 11 and the upper support element 15 for providing a seal therebetween.

[0100] As shown in FIG3 , the housing 10 is further provided with:

[0101] A battery cell 40 for supplying power to the heating element 14; the battery cell 40 is arranged near the distal end 120, or the battery cell 40 is accommodated and mounted in the second housing portion 12;

[0102] The circuit board 60 is arranged between the battery cell 40 and the lower support element 16 to guide the current between the battery cell 40 and the heating element 14; the circuit board 60 is arranged substantially perpendicular to the longitudinal direction of the electronic atomization device 100;

[0103] A first elastic electrical contact 62 extends from the battery cell 40 to the circuit board 60, thereby conductively connecting the battery cell 40 to the circuit board 60; one end of the first elastic electrical contact 62 is welded or abutted against the circuit board 60, and the other end abuts or is detachably connected to the positive electrode / negative electrode of the battery cell 40 to form an electrically conductive connection; the first elastic electrical contact 62 is detachable from the battery cell 40;

[0104] The second elastic electrical contact 61 extends from the circuit board 60 into the lower support element 16 and is welded or contacted with the conductive pins at both ends of the heating element 14 in the lower support element 16 to form a conductive connection, thereby connecting the heating element 14 to the circuit board 60.

[0105] As shown in FIG3 , the housing 10 is further provided with:

[0106] The inner bracket 18 is located in the second shell part 12 and is located between the battery cell 40 and the circuit board 60 in the longitudinal direction; the inner bracket 18 is used to support and hold the circuit board 60 and the first elastic electrical contact 61; and the inner bracket 18 is used to at least partially accommodate and surround the battery cell 40.

[0107] An airflow sensor, such as a microphone sensor or a MEMS sensor, is also arranged on the circuit board 60, which is used to sense the airflow flowing through the airflow channel generated by the user inhaling through the air outlet 113; and then the electronic atomization device 100 and / or the circuit board 60 controls the battery cell 40 to provide power to the heating element 14 according to the sensing results of the airflow sensor, thereby heating the atomized liquid matrix to generate an aerosol.

[0108] 3 to 9 , the electronic atomization device 100 further includes:

[0109] The end cap 20 is coupled to and closes the distal end 120 of the housing 10 ; the end cap 20 is removable and detachable from the distal end 120 of the housing 10 . After being removed or detached from the distal end 120 of the housing 10 , the distal end 120 of the housing 10 can be opened or uncovered, thereby allowing the battery cell 40 to be removed from the distal end 120 of the housing 10 or to leave the housing 10 .

[0110] As shown in Figures 3 to 9, after assembly, the rear end cover 20 at least partially extends from the distal end 120 into the housing 10; and an air inlet 21 is arranged on the end cover 20 for allowing external air to enter the electronic atomization device 100 after assembly. During inhalation, the airflow path through the electronic atomization device 100 is shown by arrow R2 in Figure 3. External air enters through the air inlet 21 of the end cover 20, passes through the gap between the battery cell 40 and the housing 10, and is delivered to the lower support element 16 before being delivered to the heating element 14. The aerosol is carried from the atomization chamber and output through the aerosol output tube 111 to the air outlet 113 for inhalation by the user.

[0111] In order to form a detachable connection between the end cap 20 and the distal end 120 of the housing 10, referring to Figures 3 to 9, the electronic atomization device 100 further includes:

[0112] Connecting element 19, in this embodiment, is located within housing 10 and disposed at distal end 120. Connecting element 19 and second housing portion 12 of housing 10 are securely connected to each other through a tight fit, such as riveting or interference fit. In use, end cap 20 is detachably connected to connecting element 19, thereby establishing a detachable connection with housing 10. In some embodiments, connecting element 19 is made of a rigid alloy, such as stainless steel or a polymer plastic.

[0113] 3 to 9 , the connecting element 19 is basically arranged in an annular shape; a slot 191 for connecting to the end cover 20 is arranged on the connecting element 19; the slot 191 includes a first portion 1911 extending circumferentially, a second portion 1912 extending axially from the first portion 1911 toward the distal end 120; and the second portion 1912 is open toward the distal end 120.

[0114] As shown in FIG. 3 to FIG. 9 , the first portion 1911 has a first end 1913 and a second end 1914 opposite to each other; the second portion 1912 extends axially from the second end 1914 of the first portion 1911 .

[0115] As shown in Figures 3 to 9, the end cover 20 at least partially extends into the interior of the connecting element 19; a latching protrusion 23 is arranged on the end cover 20. During use, the latching protrusion 23 protrudes into the first part 1911 of the latch groove 191 and abuts against the first end 1913 of the first part 1911 of the latch groove 191; thereby preventing the end cover 20 from being removed or disassembled along the longitudinal direction of the housing 10.

[0116] The operation process of removing the end cover 20 is shown in Figures 7 to 9. First, the end cover 20 is rotated around the central axis to move the locking protrusion 23 from the locking position of the first end 1913 abutting against the first part 1911 to the unlocking position of the second part 1912 of the second end 1914, as shown by arrow R3 in Figure 8; then, as shown by arrow R4 in Figure 9, the end cover 20 is moved longitudinally to make the locking protrusion 23 leave the slot 191 along the second part 1912; thereby, the connection between the end cover 20 and the connecting element 19 is released, and the end cover 20 can be disassembled or removed from the distal end 120 of the housing 10.

[0117] After removing the end cap 20, the distal end 120 of the housing 10 is opened, and the battery cell 40 can be taken out or removed from the distal end 120 of the housing 10 by gently shaking or flicking. When the battery cell 40 is removed, the conductive connection is disconnected by breaking contact with the first elastic electrical contact 62.

[0118] According to the preferred embodiment shown in FIG5 , a substantially arcuate recess 1915 is disposed within first portion 1911 of latch slot 191, near first end 1913. When latch protrusion 23 of end cap 20 abuts first end 1913, it is at least partially located within recess 1915, thereby preventing latch protrusion 23 of end cap 20 from becoming loose or wobbling within first portion 1911. When a user pinches or grips end cap 20 with their fingers and rotates it, latch protrusion 23 can be easily removed from recess 1915.

[0119] According to the embodiment shown in Figures 3 to 10, an elastomer 22 is arranged in the end cover 20, so that when the end cover 20 is combined with the distal end 120 of the housing 10, the elastomer 22 elastically abuts against and supports the battery cell 40. The elastomer 22 is made of a flexible or elastic material such as silicone or TPE polymer. The elastomer 22 is connected to the second connection structure 24 of the end cover 20 via a first connection structure 222; and when the end cover 20 is rotated or moved by the user, the elastomer 22 moves with the end cover 20. In addition, the elastomer 22 can be removed from the housing 10 together with the end cover 20. An avoidance portion 221 is also arranged on the elastomer 22 to provide a channel for external air entering through the air inlet 21 to pass through the elastomer 22.

[0120] As shown in Figures 3 to 9, when the end cover 20 forms a detachable connection with the first part 1911 of the slot 191 of the connecting element 19; by rotating the end cover 20 so that the protrusion 23 abuts against the first end 1913 of the first part 1911, the locking position of the end cover 20 is defined; in the locked position, the longitudinal movement of the end cover 20 is prevented to form disassembly; and by rotating the end cover 20 so that the protrusion 23 abuts against the second end 1914 of the first part 1911, an unlocked position in which the end cover 20 is detachably connected to the connecting element 19 is formed, and then in the unlocked position, the end cover 20 can be moved longitudinally to disassemble or remove the end cover 20 from the housing 10.

[0121] In some other embodiments, the connecting element 19 may also be formed or defined by a portion of the housing 10 ; alternatively, the slot 191 is formed or defined on the housing 10 , thereby directly forming a detachable connection between the housing 10 and the end cap 20 .

[0122] Alternatively, in some alternative embodiments, the card slot 191 may also be arranged on the outer surface of the end cover 20 ; and the card protrusion 23 that cooperates with the card slot 191 to form a detachable connection is arranged on the connecting element 19 .

[0127] A liquid storage chamber 112a is defined between the aerosol output channel 111a and the housing 10a for storing a liquid matrix; the liquid storage chamber 112a is open on a side facing the distal end 120a;

[0128] The tubular element 15a, such as a stainless steel tube, a ceramic tube, or a plastic tube, extends longitudinally within the liquid storage chamber 112a. The tubular element 15a is tightly connected to the aerosol output tube forming the aerosol output channel 111a by riveting, interference fit, or other means. The tubular element 15a also has perforations or hollows 151a on its wall, allowing the liquid matrix in the liquid storage chamber 112a to pass through the perforations or hollows 151a and flow into the tubular element 15a for atomization.

[0129] The liquid-conducting element 13a is made of a capillary or porous material, such as a sponge, cotton fiber, or a porous body such as a porous ceramic. The liquid-conducting element 13a extends longitudinally within the tubular element 15a. The liquid-conducting element 13a is tubular in shape. The outer surface of the liquid-conducting element 13a can absorb and store a portion of the liquid matrix through perforations or hollows 151a in the tubular element 15a. The direction of liquid transfer is indicated by arrow R1 in FIG. 12 .

[0130] Heating element 14a is coupled to the inner surface of liquid-conducting element 13a. Heating element 14a is used to heat at least a portion of the liquid matrix within liquid-conducting element 13a to generate aerosol and release it into aerosol output channel 111a. In this preferred embodiment, heating element 14a is a cylindrical heating mesh, a spiral coil, or the like.

[0131] As shown in FIG11 and FIG12 , the electronic atomization device 100a further includes:

[0132] a support 16a, at least partially supporting the tubular element 15a and closing the opening of the liquid storage chamber 112a toward the distal end 120a;

[0133] The battery cell 40a is located in the second housing portion 12a and is arranged near the distal end 120a;

[0134] The circuit board 60a is provided with an MCU controller and circuits for guiding current between the heating element 14a and the battery cell 40a. The circuit board 60a is arranged substantially perpendicular to the longitudinal direction of the electronic atomization device 100. The circuit board 60a is arranged between the battery cell 40a and the bracket 16a.

[0135] A first elastic electrical contact 62a extends from the battery cell 40a to the circuit board 60a, thereby conductively connecting the battery cell 40a to the circuit board 60a; one end of the first elastic electrical contact 62a is welded or abutted against the circuit board 60a, and the other end abuts or is detachably connected to the positive electrode / negative electrode of the battery cell 40a to form an electrically conductive connection; the first elastic electrical contact 62a is detachable from the battery cell 40a;

[0136] The second elastic electrical contact 61a extends from the circuit board 60a into the bracket 16a and is welded or otherwise contacted with the conductive pins at both ends of the heating element 14a within the bracket 16a to form a conductive connection, thereby connecting the heating element 14a to the circuit board 60a;

[0137] The inner bracket 18a is located in the second shell part 12a and is located between the battery cell 40a and the circuit board 60a in the longitudinal direction; the inner bracket 18a is used to support and hold the circuit board 60a and the first elastic electrical contact 61a; and the inner bracket 18a is used to at least partially accommodate and surround the battery cell 40a.

[0138] 13 and 14 , the electronic atomization device 100a further includes:

[0139] The end cap 20a is coupled to and seals the distal end 120a of the housing 10a. The end cap 20a is removable and detachable from the distal end 120a of the housing 10a. After being removed or detached from the distal end 120a of the housing 10a, the distal end 120a of the housing 10a is opened or uncovered, thereby allowing the battery cell 40a to be removed from or removed from the distal end 120a of the housing 10a.

[0140] 13 and 14 , the rear end cover 20a is assembled so that at least a portion of the rear end cover 20a extends into the housing 10a from the distal end 120a. To form a detachable connection between the end cover 20a and the distal end 120a of the housing 10a, the electronic atomization device 100a further includes:

[0141] Connecting element 19a. In this embodiment, connecting element 19a is located within housing 10a and disposed at distal end 120a. Connecting element 19a is securely connected to second housing portion 12a of housing 10a via a tight fit such as riveting or interference fit. During use, end cap 20a is removably connected to connecting element 19a, thereby establishing a removable connection with housing 10a. In some embodiments, connecting element 19a is made of a rigid alloy, such as stainless steel or a polymer plastic.

[0142] The connecting element 19a is basically arranged into an annular shape; a card slot 191a for connecting to the end cover 20a is arranged on the connecting element 19a; the card slot 191a includes a first portion 1911a extending along the circumferential direction, and a second portion 1912a extending axially from the first portion 1911a toward the distal end 120; and the second portion 1912a is open toward the distal end 120a.

[0143] As shown in Figures 13 to 14, when the end cover 20a is connected to the distal end 120a of the housing 10a, it at least partially extends into the interior of the connecting element 19a; a latching protrusion 23a is arranged on the end cover 20a, and when in use, the latching protrusion 23a protrudes into the first part 1911a of the latch groove 191a and abuts against the first end of the first part 1911a of the latch groove 191a; thereby preventing the end cover 20a from being removed or disassembled along the longitudinal direction of the housing 10a.

[0144] The operation process of removing the end cover 20a is shown in Figure 14. First, the end cover 20a is rotated around the central axis to move the protrusion 23a from the first end of the first part 1911a to the second part 1912a at the second end, as shown by arrow R3 in Figure 14; then, as shown by arrow R4 in Figure 14, the end cover 20a is moved longitudinally to make the protrusion 23a leave the slot 191a along the second part 1912a; thereby, the connection between the end cover 20a and the connecting element 19a is released, and the end cover 20a can be disassembled or removed from the distal end 120a of the housing 10a.

[0145] After removing the end cap 20a, the distal end 120a of the housing 10a is opened, and the battery cell 40a can be taken out or removed from the distal end 120a of the housing 10a by gently shaking or flicking. When the battery cell 40a is removed, the conductive connection is disconnected by breaking contact with the first elastic electrical contact 62a.

[0146] In the embodiment shown in Figures 13 and 14 , when the end cap 20a is coupled to the distal end 120a of the housing 10a, at least a portion of the end cap 20a is exposed outside the distal end 120a of the housing 10a. A user grasps the exposed portion of the end cap 20a and rotates and moves it, thereby detaching and removing the end cap 20a from the housing 10a. Furthermore, in Figures 13 and 14 , the exposed portion of the end cap 20a is provided with a plurality of circumferentially spaced recesses 211a. This increases friction and prevents slipping when the user's fingers grasp the end cap 20a for rotation and movement, thereby enhancing user convenience.

[0147] According to the embodiments shown in Figures 12 to 15 , an elastomer 22a is disposed on the end cap 20a. When the end cap 20a is coupled to the distal end 120a of the housing 10a, the elastomer 22a elastically abuts against and supports the battery cell 40a. The elastomer 22a is made of a flexible or elastic material, such as silicone or TPE polymer. The elastomer 22a is securely connected to the end cap 20a; when the end cap 20a is rotated or moved by a user, the elastomer 22a moves with the end cap 20a. Furthermore, the elastomer 22a can be removed from the housing 10a along with the end cap 20a.

[0148] According to the embodiments shown in Figures 12 to 23, an operating component 30a is also arranged in the end cover 20a for the user to operate to selectively open and close the air inlet 21a on the end cover 20a, thereby selectively allowing or preventing air from passing through the electronic atomization device 100a to prevent the output of aerosol when aerosol output is not desired.

[0149] Specifically, as shown in FIG. 12 to FIG. 23 , the structure inside the end cover 20 further includes:

[0150] cylindrical outer wall;

[0151] The partition wall 25a is arranged perpendicular to the longitudinal direction of the end cap 20a or the housing 10a and is located inside the outer wall. The partition wall 25a includes a first side and a second side that are opposite to each other in the longitudinal direction of the end cap 20a or the housing. The partition wall 25a divides the interior space of the end cap 20a into two separate spatial portions located on the first side and the second side, respectively. Specifically, the partition wall 25a divides the interior space of the end cap 20a into the following longitudinal sections:

[0152] a first installation space 26a, adjacent to a first side of the partition wall 25a;

[0153] The second installation space 27a is close to the second side of the partition wall 25a.

[0154] Furthermore, the first installation space 26a faces the battery cell 40a. A fourth connection structure 261a connected to the elastic body 22a is arranged on the inner surface of the first installation space 26a. Therefore, when the end cap 20a is rotated or moved by a user, the elastic body 22a moves along with the end cap 20a.

[0155] As shown in Figures 12 to 23, the structure inside the end cover 20a also includes:

[0156] The air inlet 21a is arranged on the partition wall 25a to allow external air to enter the electronic atomization device 100a.

[0157] As shown in Figures 12 to 23, the structure of the operating component 30a includes:

[0158] The connecting element 34a, the sealing element 32a and the operating element 31a are arranged in the longitudinal direction.

[0159] After assembly, the operating element 31a is mainly installed and accommodated in the second installation space 27a, and the operating element 31a is at least partially exposed at the distal end 120a, thereby allowing the user to operate, such as by pressing and rotating the operating element 31a.

[0160] The sealing element 32a is located in the first installation space 26a of the end cover 20a and can be moved by the operating element 31a to selectively close or open the air inlet 21a;

[0161] The connecting element 34a is combined with or connected to the sealing element 32a and is connected to the operating element 31a, thereby establishing a connection between the operating element 31a and the sealing element 32a so that a user can drive the movement of the sealing element 32a by operating the operating element 31a.

[0162] In some embodiments, driving the sealing element 32a to move includes movement in the longitudinal direction of the end cap 20a and / or the housing 10a, and includes rotation about the central axis of the end cap 20a and / or the housing 10a.

[0163] As shown in FIG. 12 to FIG. 23 , the connecting element 34 a is a conventional countersunk screw, which penetrates the sealing element 32 a and is connected to the operating element 31 a through threads.

[0164] As shown in Figures 12 to 23, the sealing element 32a is provided with a relief notch 321a. Furthermore, the sealing element 32a can be rotated about the central axis of the end cap 20a and / or the housing 10a by the operating element 31a, thereby aligning or misaligning the relief notch 321a with or away from the air inlet 21a on the partition wall 25a, thereby selectively opening or closing the air inlet 21a. In some embodiments, the sealing element 32a is made of a flexible material such as silicone or a thermoplastic elastomer.

[0165] As shown in Figures 12 to 23, a first connecting structure 322a, such as a protrusion, is arranged on the sealing element 32a; accordingly, a second connecting structure 262a, such as a recess defined by the protrusion 263a, is arranged on the first side of the partition wall 25a; when the sealing element 32a is located in the closed position closing the air inlet 21a, the first connecting structure 322a, such as the protrusion, extends into the second connecting structure 262a, such as the recess, to form a connection to form a locking state, thereby stably maintaining the sealing element 32a in the closed position and preventing the sealing element 32a from rotating.

[0166] According to the embodiments shown in Figures 12 to 23, the operating component 30a / sealing element 32a can be operated by the user by pressing the operating element 31a to move the operating component 30a / sealing element 32a in the longitudinal direction, thereby disengaging the first connecting structure 322a and the second connecting structure 262a from each other to unlock the connection between the first connecting structure 322a and the second connecting structure 262a in the closed position to form an unlocked state.

[0167] According to the embodiments shown in Figures 12 to 23, a plurality of first positioning recesses 271a and second positioning recesses 272a extending in the longitudinal direction are arranged on the inner surface of the second installation space 27a of the end cover 20a; a positioning protrusion 313a is arranged on the outer surface of the operating element 31a; so that when the user drives the operating element 31a to rotate from the closed position to the open position, or from the open position to the closed position by means of a finger, the positioning protrusion 313a is snapped into one of the first positioning recess 271a and the second positioning recess 272a to provide positioning in the open position, and is snapped into the other of the first positioning recess 271a and the second positioning recess 272a to provide positioning in the closed position.

[0168] According to the embodiments shown in Figures 12 to 23, a longitudinally extending first limiting protrusion 273a is arranged on the inner surface of the second installation space 27a of the end cover 20a, so as to abut against the second limiting protrusion 314a arranged on the outer surface of the operating element 31a to form a limit, so as to limit the angle of the operating element 31a during rotation between the first limiting protrusion 273a, so as to prevent the rotation operation of the operating element 31a from deviating from the angle range defined by the first limiting protrusion 273a.

[0169] To facilitate the user's rotation of the operating element 31a, the surface of the operating element 31a exposed at the distal end 120a has radially arranged operating ridges 311a; the user can rotate the operating element 31a by pinching the operating ridges 311a with fingers.

[0170] According to the embodiment shown in FIG. 12 to FIG. 23 , the operating component 30a further includes:

[0171] The elastic element 33a is used to provide elastic force to bias the sealing element 32a toward the partition wall 25a, so that the sealing element 32a drives the first connecting structure 322a to connect with the second connecting structure 262a in the closed position to form a lock.

[0172] According to the embodiment shown in Figures 12 to 23, the elastic element 33a includes a linear spring; and in assembly, the elastic element 33a is located in the second installation space 27a and abuts and is arranged between the partition wall 25a and the operating element 31a.

[0173] The user operates the operating component 30a with a finger, thereby driving the operating component 30a to move and thus opening or closing the air inlet 21a. The operation process is shown in Figures 20 to 23.

[0174] FIG20 shows a schematic diagram of the operating assembly 30a in the closed position. In FIG20 , the sealing element 32a abuts against or adheres to the first side of the partition wall 25a, blocking and closing the air inlet 21a. In the closed position of FIG20 , the elastic force of the elastic element 33a biases the sealing element 32a toward the partition wall 25a, maintaining the sealing element 32a against or adheres to the partition wall 25a and maintaining the first connecting structure 322a locked with the second connecting structure 262a.

[0175] Figure 21 shows a schematic diagram of a user unlocking the operating assembly 30a in the closed position shown in Figure 20 by pressing the operating element 31a. As indicated by arrow P11 in Figure 21, the user's finger pressure, for example, drives the operating element 31a toward the proximal end 110a, causing the sealing element 32a to separate from the partition wall 25a. Furthermore, the first connecting structure 322a of the sealing element 32a disengages from the second connecting structure 262a of the end cap 20a, thereby unlocking the device. In Figure 21, the elastic element 33a installed between the partition wall 25a and the operating element 31a is compressed.

[0176] Figure 22 shows a schematic diagram of a user rotating the operating element 31a in Figure 21 to rotate the operating assembly 30a to the open position. As indicated by arrow P12 in Figure 22 , the user's finger rotates the operating element 31a in Figure 22 , driving the sealing element 32a to the open position. In Figure 22 , the relief notch 321a of the sealing element 32a is aligned with the air inlet 21a on the partition wall 25a. The rotation of the sealing element 32a may be about the central axis m.

[0177] FIG23 shows that the elastic restoring force of the elastic element 33a drives the operating element 31a in FIG22 to move, as indicated by arrow P13 in FIG23 , thereby causing the sealing element 32a to move to abut or abut against the partition wall 25a to form a stop. Furthermore, in this position, the avoidance notch 321a of the sealing element 32a is aligned with the air inlet 21a on the partition wall 25a, allowing air to enter the electronic atomization device 100a through the air inlet 21a, as indicated by arrow R2 in FIG23 .

[0178] As shown in Figure 23, there is a gap between the operating element 31a located in the second installation space 27a and the end cover 20a, so that the air inlet 21a remains connected to the outside atmosphere through the gap between them; the port of the air inlet 21a on the second side of the partition wall 25a is always connected to the outside atmosphere; and the sealing element 32a rotates in the first installation space 26a to selectively block or avoid the port of the air inlet 21a on the first side of the partition wall 25a, thereby opening or closing the air inlet 21a.

[0179] Similarly, when the user operates along the reverse operation process from FIG. 20 to FIG. 23 , the operating component 30 a can be adjusted from the open position of FIG. 23 to the closed position of FIG. 20 .

[0180] Similarly, in some other variations of the embodiments, the end cover 20a can also be locked by connecting the third connecting structure arranged in the open position with the first connecting structure 322a of the sealing element 32a to prevent the sealing element 32a from rotating from the open position toward the closed position; and similarly, when the third connecting structure and the first connecting structure 322a of the sealing element 32a are released from the connection by pressing to separate them to form an unlocked state, the user can drive the sealing element 32a to rotate from the open position toward the closed position.

[0181] 24 to 27 show schematic diagrams of an electronic atomization device 100b according to another variant embodiment. In this embodiment, the electronic atomization device 100b includes:

[0182] The housing 10b has a proximal end 110b and a distal end 120b which are opposite to each other in the longitudinal direction. In use, the proximal end 110b is the end close to the user for suction; the distal end 120b is the end away from the user.

[0183] As shown in FIG. 26 , the electronic atomization device 100b further includes a liquid storage chamber 112b for storing a liquid matrix, and an atomization assembly for drawing the liquid matrix from the liquid storage chamber 112b and heating and atomizing the liquid matrix. To facilitate vaporization and delivery, the liquid storage chamber 112b and the atomization assembly are both positioned near the proximal end 110b.

[0184] The atomization assembly includes a liquid-conducting element 13b, which is made of a capillary or porous material, such as a sponge, cotton fiber, or a porous body such as a porous ceramic. In this embodiment, as shown in FIG26 , the liquid-conducting element 13b is arranged perpendicular to the longitudinal direction of the housing 10b. The liquid-conducting element 13b is in fluid communication with the liquid storage chamber 112b to draw the liquid matrix from the liquid storage chamber 112b.

[0185] The atomizing assembly further includes a heating element 14b to heat the liquid aerosol-forming matrix to form a smokeable aerosol. The heating element 14b may be a resistive heating element, an electromagnetic induction heating element, an infrared radiation heating element, or the like. In this embodiment, as shown in FIG26 , the heating element 14b is a spiral coil, a heating mesh, or the like that surrounds or wraps around a portion of the liquid-conducting element 13b. In other embodiments, the atomizing assembly may further include an ultrasonic atomizing sheet that generates high-frequency oscillations to ultrasonically atomize the liquid aerosol-forming matrix to form a smokeable aerosol.

[0186] The electronic atomization device 100b further includes: a battery core 40b for supplying power to the heating element 14b; the battery core 40b is arranged near the distal end 120b.

[0187] Please refer to Figures 28 to 30, the electronic atomization device 100b also includes: an end cover 20b, which at least partially closes the distal end 120b of the shell 10b and is detachably connected to the shell 10b; the end cover 20b is configured to be removable from the shell 10b to open the distal end 120b of the shell 10b, thereby being used to remove the battery cell 40b from the distal end 120b of the shell 10b; the end cover 20b can be operated by the user to selectively transition between a locked position A and an unlocked position B, and the end cover 20b is allowed to be removed from the shell 10b in the unlocked position B, and is prevented from being removed from the shell 10b in the locked position A.

[0188] The end cap 20b is configured to be rotationally movable along the longitudinal direction of the housing 10b by a first predetermined distance to transition from the locked position to the unlocked position, and to be linearly movable along the longitudinal direction of the housing 10b by a second predetermined distance in the unlocked position to be detached from the housing 10b.

[0189] In some embodiments, as shown in FIG. 29 , when the end cover 20b is in the unlocked position B, a gap space 50b is formed between the end cover bottom 200b and the distal end 120b of the housing 10b, so that the user can reach into the gap space 50b to operate the end cover 20b and remove the end cover 20b from the housing 10b.

[0190] Furthermore, to form a detachable connection between the end cap 20b and the distal end 120b of the housing 10b, as shown in Figures 28 to 31, the electronic atomization device 100b also includes: a connecting element 19b, which is located within the housing 10b and arranged at the distal end 120b; the connecting element 19b and the housing 10b can be tightly connected to each other by a tight fit such as riveting or interference fit; the connecting element 19b is basically arranged in an annular shape and at least partially surrounds the end cap 20b; in use, the end cap 20b is detachably connected to the connecting element 19b, thereby establishing a detachable connection with the housing 10b. In some embodiments, the connecting element 19b can be made of a rigid alloy such as stainless steel or a polymer plastic.

[0191] In some embodiments, a detachable connection is established between the connecting element 19b and the end cover 20b via a slot 191b and a protrusion 23b; the slot 191b is arranged on one of the connecting element 19b and the end cover 20b, and the protrusion 23b is arranged on the other of the connecting element 19b and the end cover 20b.

[0192] Please refer to Figure 28. The card slot 191b includes a first part 1911b extending obliquely relative to the longitudinal direction of the shell 10b, and a second part 1912b extending from the first part 1911b along the longitudinal direction of the shell 10b. The card protrusion 23b is arranged to define the locking position A of the end cover 20b by extending into the first part 1911b, and the card protrusion 23b is arranged to be able to move from the first part 1911b to the second part 1912b to enable the end cover 20b to be transferred from the locking position A to the unlocking position B.

[0193] Furthermore, the angle between the first portion 1911b and the second portion 1912b is an obtuse angle; specifically, the angle between the first portion 1911b and the second portion 1912b is between 90° and 135°.

[0194] Since the first part 1911b is arranged to extend obliquely relative to the longitudinal direction of the shell 10b, and the second part 1912b extends from the first part 1911b along the longitudinal direction of the shell 10b, the latch 23b is moved obliquely from the first part 1911b to the second part 1912b along the longitudinal direction of the shell 10b, so that when the end cover 20b is changed from the locked position A to the unlocked position B, a gap space 50b is formed between the end cover 20b and the distal end 120b of the shell 10b, which makes it convenient for the user to reach into the gap space 50b and pull the end cover 20b out of the shell 10b along the second part 1912b.

[0195] In some embodiments, the second portion 1912b terminates at the distal end 120b of the housing 10b and defines an opening at the distal end 120b to facilitate the removal of the protrusion 23b from the opening along the second portion 1912b, thereby facilitating the user to remove the end cap 20b from the housing 10b.

[0196] Furthermore, the first portion 1911b includes a first end 1913b and a second end 1914b that are opposite to each other, and the second portion 1912b is arranged to extend from the second end 1914b of the first portion 1911b along the longitudinal direction of the housing 10b.

[0197] In some embodiments, referring to Figures 31 and 32, a slot 191b is provided on the connecting element 19b, and the slot 191b includes a first portion 1911b extending obliquely along the longitudinal direction of the housing 10b, and a second portion 1912b extending from a second end 1914b of the first portion 1911b along the longitudinal direction of the housing 10b and toward the distal end 120b; and, the second portion 1912b is open toward the distal end 120b.

[0198] The latching protrusion 23b is provided on the end cover side wall 201b. When in use, the latching protrusion 23b protrudes into the first portion 1911b and abuts against the first end 1913b of the first portion 1911b, thereby preventing the end cover 20b from being removed or disassembled along the longitudinal direction of the housing 10b.

[0199] 28 to 30 , the end cap 20b is first rotated about the central axis so that the latching protrusion 23b moves from the locked position A against the first end 1913b to the unlocked position B of the second portion 1912b of the second end 1914b, as shown by arrow R1 in FIG7 . During the movement of the latching protrusion 23b, the end cap bottom 200b gradually moves away from the distal end 120b of the housing 10b. When the latching protrusion 23b is in the unlocked position B, a gap space 50b is formed between the end cap bottom 200b and the distal end 120b. Then, as shown by arrow R2 in FIG8 , the end cap 20b is moved longitudinally so that the latching protrusion 23b leaves the latching groove 191b along the second portion 1912b. This releases the connection between the end cap 20b and the connecting element 19b, and the end cap 20b can then be disassembled or removed from the distal end 120b of the housing 10b.

[0200] It is worth noting that during the rotation of the end cover 20b in the direction of arrow R1, since the first part 1911b is arranged to extend obliquely along the longitudinal direction of the shell 10b, the protrusion 23b moves along the first part 1911b, and the bottom 200b of the end cover gradually moves away from the distal end 120b of the shell 10b, thereby forming a gap space 50b, so that the user can easily lift the gap space 50b and easily move the end cover 20b out from the second part 1912b in the direction of arrow R2.

[0201] In some embodiments, the first end 1913b of the first portion 1911b is provided with a stop step 1915b for the latching protrusion 23b to abut. The latching protrusion 23b abuts against the stop step 1915b to prevent the end cap 20b from moving from the locked position A to the unlocked position B. To unlock the end cap 20b, the user pinches or grips the end cap 20b with their fingers and rotates it in the direction of arrow R1, separating the latching protrusion 23b from the stop step 1915b and thereby moving the latching protrusion 23b out of the locked position A. The end cap 20b can then be rotated so that the latching protrusion 23b rotates through the first portion 1911b into the second portion 1912b, thereby achieving the unlocked position of the end cap 20b. The user then grips the end cap 20b and pulls it in the direction of arrow R2, moving the latching protrusion 23b out of the slot 191b along the second portion 1912b, thereby removing the end cap 20b from the housing 10b.

[0202] According to the preferred embodiment shown in Figures 28, 31, and 33, the retaining step 1915b of the first end 1913b is a curved protrusion; the edge of the latching protrusion 23b is provided with a curved recess 230b that matches the curved protrusion. When the latching protrusion 23b abuts the first end 1913b, the curved protrusion is located within the curved recess 230b, thereby preventing the latching protrusion 23b from loosening or shaking in the first portion 1911b. When a user pinches or grips the end cap 20b with their fingers and rotates it, the curved protrusion and the curved recess 230b are easily separated, thereby moving the latching protrusion 23b out of the locked position A.

[0203] FIG37 shows a schematic diagram of a connecting element 19c according to another alternative embodiment; in this embodiment, the slot 191c arranged on the connecting element 19c includes:

[0206] The first end of the first portion 1911c is provided with an abutment step 1913c. When the end cap 20b is in the locked position, the latching protrusion 23b abuts against the abutment step 1913c to form a stop, thereby preventing the end cap 20b from rotationally moving to the unlocked position B. To unlock the end cap 20b, the user presses the end cap 20b, as indicated by arrow P21 in FIG. 37 , causing the latching protrusion 23b to move relative to the abutment step 1913c and thereby disengage from the abutment step 1913c. The end cap 20b can then be rotated so that the latching protrusion 23b pivots through the first portion 1911c into the second portion 1912c, thereby achieving the unlocked position of the end cap 20b. The user then grasps the end cap 20b and pulls it, causing the latching protrusion 23b to move along the second portion 1912c out of the latching slot 191c, releasing the detachable connection and allowing the end cap 20b to be removed from the housing 10b.
