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. Typically, the elongated body may be formed by a single integral housing, or the elongated housing may be formed by two or more separable bodies.

[0053] For example, the electronic atomization device 100 can have a control body at one end, which has a shell containing one or more reusable components (for example, batteries such as rechargeable cells and / or rechargeable supercapacitors, and various electronic devices for controlling the operation of the product), and an outer body or housing for suction at the other end.

[0054] In some embodiments, the outer body or housing of the electronic atomization device 100 substantially defines the outer surface of the electronic atomization device 100; Figure 1 to Figure 2 In the specific embodiment shown, the electronic atomization device 100 includes:

[0055] The housing 10 may include one or more reusable components; the housing 10 has a proximal end 110 and a distal end 120 opposite to each other in the longitudinal direction; in use, the proximal end 110 is the end close to the user for suction; the distal end 120 is the end away from the user;

[0056] In some examples, all or only a portion of housing 10 may be formed from a metal or alloy such as stainless steel, aluminum, or other suitable materials including various plastics (eg, polycarbonate), metal-plating over plastic, ceramics, and the like.

[0057] In some embodiments, the housing 10 is formed from several parts. And in some embodiments, the housing 10 is open at the distal end 120. Figures 1 to 5 As shown, the housing 10 comprises:

[0058] The first shell 11 and the second shell 12 ; wherein the first shell 11 is close to or defines a proximal end 110 , and the second shell 12 is close to or defines a distal end 120 .

In an embodiment, the connecting element 19 is made of polymer plastic or a rigid alloy such as stainless steel. For example, in some embodiments, a first connecting structure such as a convex is arranged on the connecting element 19, and a second connecting structure such as a slot is arranged on the operating element 20; and in use, the operating element 20 and the connecting element 19 are connected by the cooperation of the first connecting structure such as the convex and the second connecting structure such as the slot.

In some embodiments, when the user operates the operating element 20, the operating element 20 remains connected to the connecting element 19, thereby preventing the operating element 20 from being removed from the connecting element 19 and / or the housing 10.

[0066] according to Figures 1 to 5 As shown, the electronic atomization device 100 also includes:

[0067] An air outlet 113 for the user to inhale; the air outlet 113 is located at the proximal end 110 of the housing 10 and is defined or formed by the first housing 11;

To facilitate vaporization and output, the liquid storage chamber 112 and the atomizing assembly are both arranged near the proximal end 110. The electronic atomization device 100 also includes an aerosol output tube 111 arranged in the longitudinal direction, which at least partially extends in the liquid storage chamber 112, and the liquid storage chamber 112 is formed by the space between the aerosol output tube 111 and the inner surface of the housing 10 / first housing 111. 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.

Or in some other variations, the first liquid-conducting element 51 includes artificial cotton, or hard artificial cotton or artificial foam made of filamentous polyurethane. For example, the first liquid-conducting element 51 uses 138# hard synthetic organic polymer fibers with a viscosity of 0.1 to 0.9 mg / mm 3The density of the first liquid-conducting element 51 is about 0.04-0.06g when not soaked in liquid. The first liquid-conducting element 51 is made of oriented fibers that are basically oriented along the length direction, width direction or radial direction. The oriented fibers are arranged in the length direction or width direction of the first liquid-conducting element 51, so that the first liquid-conducting element 51 has a strong bending resistance and is hard.

According to Figure 3 As shown by the middle arrow R1, the liquid aerosol-generating matrix in the liquid storage chamber 112 is absorbed through the upper surface of the first liquid-conducting element 51, and then flows to the through-hole 141 of the tubular element 14 through the lower surface of the first liquid-conducting element 51, and finally passes through the through-hole 141 of the tubular element 14 and is absorbed by the second liquid-conducting element 52.

[0076] See also Figure 3 As shown, the housing 10 is also provided with:

[0077] The support 60 is used to support and fix the first liquid-conducting element 51 and the tubular element 14. The support 60 is generally cylindrical in shape and is rigid, for example, the support 60 is made of hard polymer plastic.

[0078] See also Figure 3 As shown, the housing 10 is also provided with:

[0079] The circuit board 16 is fixed or installed in the bracket 60 to guide the current between the battery cell 70 and the heating element 40; the circuit board 60 is basically arranged perpendicular to the longitudinal direction of the electronic atomization device 100;

[0080] The first electrical contact 171 extends from the circuit board 16 toward the distal end 120; the first electrical contact 171 is used to abut against or contact the electrode tab on the surface of the battery cell 70, so as to conductively connect the circuit board 16 with the battery cell 70; the first electrical contact 171 and the battery cell 70 are elastically abutted and thus separable;

[0081] The second electrical contact 172 extends from the circuit board 60 toward the proximal end 110 and is welded or contacted with the conductive pins at both ends of the heating element 40 in the bracket 60 to form a conductive connection, thereby connecting the heating element 40 to the circuit board 16 .

[0082] In some embodiments, the first electrical contact 171 and / or the second electrical contact 172 are elastic electrical contacts that can be compressed; for example, the first electrical contact 171 is a conductive spring pin.

[0083] See also Figures 1 to 5 As shown, the housing 10 is also provided with:

[0084] The support element 18 is arranged between the battery cell 70 and the circuit board 16 to provide the battery cell 70 with abutment; after assembly, the first electrical contact 171 at least partially extends into or passes through the support element 18;

[0085] The retaining element 80 is arranged in a cylindrical shape extending in the longitudinal direction of the housing 10; the upper end of the retaining element 80 is connected to the supporting element 18 by riveting or snapping, and the lower end is connected to the operating element 20 by riveting or snapping, so that the retaining element 80, the supporting element 18 and the operating element 20 jointly define a storage space surrounding and retaining the battery cell 70; after assembly, the battery cell 70 is securely accommodated in the retaining element 80. And after assembly, the end of the battery cell 70 toward the distal end 120 is abutted against the operating element 20 to form a stop.

[0086] according to Figures 3 to 5 As shown, the operating element 20 is also provided with a connecting portion 23 extending into the retaining element 80; Figure 5 In the illustrated embodiment, the connection portion 23 of the operating element 20 is in the shape of an annular flange; and the connection portion 23 of the operating element 20 and the retaining element 80 are securely connected to each other through interference fit and tight fit.

[0087] according to Figure 4 As shown, after assembly, the battery cell 70, the holding element 80, the supporting element 18, and the operating element 20 are firmly combined to form a battery cell assembly. The battery cell assembly can be moved and rotated as a whole by actuating the operating element 20 by a user.

[0088] according to Figure 4 As shown, the support element 18 is provided with a central hole 181 for one of the first electrical contacts 171 to penetrate and connect to the positive pole ear of the battery cell 70; the support element 18 is provided with an arc-shaped avoidance recess 182 located at the edge, which is used for another of the first electrical contacts 171 to penetrate and connect to the negative pole ear of the battery cell 70; and the arc-shaped avoidance recess 182 can avoid the support element 18 and the other of the first electrical contacts 171 without blocking their relative rotation when the user rotates the operating element 20 to rotate the battery cell assembly. In addition, the walls at both ends of the avoidance recess 182 are used to provide a limit when the user rotates the battery cell assembly; for example, when the user rotates the operating element 20 to rotate the battery cell assembly, the operating element 20 abuts against the first end 1821 of the avoidance recess 182 when it rotates to the first position, and abuts against the second end 1822 of the avoidance recess 182 when it rotates to the second position, thereby providing a limit for the rotation operation.

[0089] and in Figures 3 to 11In the embodiment, the avoidance recess 182 has a through hole passing through the support element 18 at the first end 1821, so that one of the first electrical contacts 171 passes through the support element 18 and then abuts against the electrode ear on the surface of the battery cell 70 for conduction; and the avoidance recess 182 does not have a through hole passing through the second end 1822, and when the first electrical contact 171 rotates to the second end 1822, it cannot pass through the support element 18 and abut against the electrode ear on the surface of the battery cell 70 for conduction.

[0090] There is a gap between the holding element 80 and the housing 10, so that a path channel for air flow is defined by the gap therebetween. Figure 3 As shown, after assembly, the operating element 20 at least partially extends from the distal end 120 into the housing 10; and an air inlet 21 is arranged on the operating element 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 in FIG. Figure 3 As shown by the middle arrow R2, external air enters from the air inlet 21 of the operating element 20, flows to the supporting element 18 through the gap between the retaining element 80 and the housing 10, and then enters the bracket 60 after passing through the supporting element 18 and the circuit board 16, and is delivered to the heating element 40 through the channel in the bracket 60, and then carries the aerosol and is output to the air outlet 113 through the aerosol output tube 111 to be inhaled by the user.

[0091] In some embodiments, the user can selectively move the operating element 20 between the first position and the second position by operating the operating element 20; and the user can drive the holding element 80 and / or the battery cell 70 and / or the battery cell assembly to move between the third position and the fourth position by operating the operating element 20. The battery cell 70 is in contact with the first electrical contact 171 at the third position to be in conduction, and is separated from the first electrical contact 171 at the fourth position to stop conducting. Specifically:

[0092] When the operating element 20 is located at the first position, the battery cell 70 is located at the third position; and when the user rotates the operating element 20 to the second position, the battery cell 70 is driven by the operating element 20 to move from the third position to the fourth position accordingly.

[0093] In some embodiments, an airflow sensor (not shown in the figure) is arranged on the circuit board 16 to sense the change of airflow flowing through the inside of the electronic atomization device 100 during the user's inhalation to determine the user's inhalation action. When the battery cell 70 is in the third position, the airflow sensor is connected to the battery cell 70 through the circuit board 16, and can be powered by the battery cell 70 to sense the airflow; when the battery cell 70 is in the fourth position, the airflow sensor is disconnected from the battery cell 70, and the airflow sensor is in a power-off state and does not sense the airflow.

[0094] In some embodiments, the operating element 20 can be operated by the user to selectively switch between the locked state and the unlocked state, and in the unlocked state, the user can be allowed to rotate the operating element 20 to move the operating element 20 between the first position and the second position, and when locked, the user is prevented from rotating the operating element 20 to move the operating element 20 between the first position and the second position. In addition, the operating element 20 can be operated by the user in the unlocked state to drive the battery cell 70 to move between the third position and the fourth position; and when the operating element 20 is in the locked state, the user can be prevented from rotating the operating element 20 to prevent the battery cell 70 and / or the battery cell assembly from moving between the third position and the fourth position.

When the operating element 20 is located at the first position, the engaging protrusion 22 is opposite to the first engaging groove 191; and, when the engaging protrusion 22 is inserted into the first engaging groove 191, the operating element 20 is locked in the first position, so as to prevent the user from rotating the operating element 20. When the operating element 20 is located at the first position, the engaging protrusion 22 is opposite to the second engaging groove 192; and, when the engaging protrusion 22 is inserted into the second engaging groove 192, the operating element 20 is locked in the second position, so as to prevent the user from rotating the operating element 20. Accordingly, when the user pulls the operating element 20, the engaging protrusion 22 is disengaged from the first engaging groove 191 and / or the second engaging groove 192 to be unlocked, and then the user can rotate the operating element 20. According to Figure 5 As shown, the length of the first card slot 191 is greater than the length of the second card slot 192 .

[0096] For example Figure 6 FIG. 1 shows a schematic diagram of the operating element 20 being locked in the first position. When the operating element 20 is locked in the first position, the locking protrusion 22 is completely inserted into the first locking groove 191. Figure 6 In the embodiment, the protrusion 22 of the operating element 20 is inserted into the first slot 191. And, the operating element 20 is in contact with the distal end 120 of the housing 10. And in Figure 6 In the state, the battery cell 70 is at least partially abutted against and supported by the operating element 20, and the battery cell 70 is in the third position at this time and elastically contacts the first conductive contact 171 to form conduction.

[0097] For example Figure 7 Shows the user through the Figure 6 A schematic diagram of pulling out the operating element 20 at the first position to unlock the operating element 20; according to Figure 7As shown by the middle arrow P11, the user pulls the operating element 20 to form a first distance d11 between the operating element 20 and the distal end 120 of the housing 10. At this time, as the operating element 20 is pulled, the battery cell 70 in the battery cell assembly moves longitudinally by the first distance d11 and is separated from the first conductive contact 171 to disconnect the conduction, as shown in FIG. Figure 8 shown.

[0098] For example Fig. 9 Shows the Figure 7 Schematic diagram of the unlocked operating element 20 rotating to the second position; according to Fig. 9 As shown by the middle arrow P12, in the second position, the operating element 20 is operated to align the locking protrusion 22 with the second locking groove 192, and the battery cell 70 and / or the battery cell assembly moves to the fourth position. Fig.10 As shown by the arrow P13, the user moves to Fig. 9 The operating element 20 is pressed or the elastic restoring force provided by the elastic element 82 causes the locking protrusion 22 to extend into the second locking groove 192 to lock the operating element 20 in the second position. When the operating element 20 is locked in the second position, the locking protrusion 22 only partially extends into the second locking groove 192 and is partially located outside the second locking groove 192.

[0099] Fig.11 Shows Fig.10 A cross-sectional diagram of the electronic atomization device 100 in the second position and locked; Fig.10 As shown in , there is a second distance d12 between the operating element 20 and the distal end 120 of the housing 10; and the second distance d12 is smaller than the first distance d11. Fig.11 As shown in FIG. , the battery cell 70 is in the fourth position, which is separated from the first electrical contact 17 and thus disconnected from the circuit board 16 .

[0100] In some embodiments, a positioning structure or indication is arranged on the connecting element 19 and / or the housing 10 to provide a user with a positioning or indication for rotating the operating element 20 to the first position and / or the second position. The positioning structure or indication may be a scale or text indication on the housing 10, or a position-limiting protrusion on the inner wall of the connecting element 19, etc., to provide a positioning or indication of the position of the user rotating the operating element 20 by means of structural limiting or visual indication.

[0101] according to Figures 3 to 11 As shown, a flange 81 extending in the circumferential direction is also arranged on the outer surface of the retaining element 80. The housing 10 is also arranged with:

[0102] The elastic element 82 is, for example, a spring elastically pressed against the flange 81 of the retaining element 80 and the connecting element 19. The elastic element 82 is used to provide elasticity so that the operating element 20 can be moved from the unlocked state to the locked state when it is rotated to the first position and / or the second position, or the operating element 20 is biased toward the locked state in the first position and / or the second position.

[0103] according to Figures 3 to 11 As shown, the flange 81 and the elastic element 82 are arranged in alignment with the connecting element 19 in the longitudinal direction; when the user pulls the operating element 20 to unlock, the connecting element 19 blocks the flange 81 / elastic element 82 to prevent the battery cell assembly 70 from being pulled out from the distal end 120 of the housing 10. Accordingly, due to the blocking of the connecting element 19, the user cannot remove or disassemble the operating element 20 from the distal end 120 of the housing 10 during operation.

[0104] or Fig.12 A schematic diagram of an electronic atomization device 100b of another variant embodiment is shown; in this embodiment, the electronic atomization device 100b arranges an operating element 90b for user operation near the center of the housing 10b, rather than at the distal end 120 of the previous embodiment. In this embodiment, the electronic atomization device 100b includes:

[0105] The housing 10b includes a first shell 11b near or defining a proximal end 110b, and a second shell 12b near or defining a distal end 120b;

[0106] an aerosol output tube 111b extending from an air outlet 113b of the proximal end 110b toward a distal end 120b;

[0107] A liquid storage chamber 112b for storing a liquid aerosol generating substrate;

[0108] The first liquid guiding element 51b is used to absorb the liquid aerosol from the liquid storage chamber 112b to generate the matrix;

[0109] The tubular element 14b passes through the first liquid-conducting element 51b and is connected to the aerosol output tube 111b; the tubular element 14b is provided with a perforation 141b; the tubular element 14b is provided with an atomizing assembly in fluid communication with the first liquid-conducting element 51b, so as to receive the liquid aerosol-generating substrate from the first liquid-conducting element 51b and heat and atomize it to generate an aerosol; the atomizing assembly includes a second liquid-conducting element 52b and a heating element 40b located in the second liquid-conducting element 52b;

[0110] A support 60b, surrounding and supporting the first liquid-conducting element 51b and the tubular element 14b;

[0111] The circuit board 16b, and the first electrical contact 171b extending from the circuit board 16b toward the distal end 120b, and the second electrical contact 172b extending from the circuit board 16b toward the proximal end 110b; the heating element 40b is connected to the second electrical contact 172b through a conductive lead, and is further conductively connected to the circuit board 16b;

[0112] The battery cell assembly includes a supporting element 18b and a retaining element 80b, and a battery cell 70b; the retaining element 80b is configured to be cylindrical so as to surround and accommodate the battery cell 70b; the supporting element 18b is combined with the upper end of the retaining element 80b to provide the battery cell 70b with abutment;

[0113] The end cap 20b is connected to the connecting element 19b to close the distal end 120b of the housing 10b; the end cap 20b is provided with an air inlet 21b. In this embodiment, the end cap 20b is not connected to the battery cell assembly, and the user does not operate the end cap 20b to drive the battery cell assembly to move between the third position and the fourth position.

[0114] In the electronic atomization device 100b of this embodiment, the operating element 90b operated by the user is configured to be annular in shape and is arranged around and combined with a portion of the housing 10b. The operating element 90b can be operated by the user, for example, the operating element 90b is moved between the first position and the second position by a rotation operation around the housing 10b and / or an operation of moving along the longitudinal direction of the housing 10b. The operating element 90b is provided with a protrusion 91b that penetrates the housing 10b.

[0115] according to Fig.12 and Fig.13 As shown, a spiral groove 811b arranged around the retaining element 80b is arranged on the outer surface of the retaining element 80b; a first locking groove 812b extending longitudinally from the first end of the spiral groove 811b, and a second locking groove 813b extending longitudinally from the second end of the spiral groove 811b.

[0116] Accordingly, after assembly, the protrusion 91b of the operating element 90b is inserted into the spiral groove 811b to form a connection, so that the user can rotate the operating element 90b, for example Fig.13 As shown by the arrow P22 in the middle, the retaining element 80b and / or the battery cell assembly are moved in the longitudinal direction. For example, the battery cell assembly and / or the battery cell 70 can be moved in the longitudinal direction between the third position and the fourth position by rotating the operating element 90b. In the third position, the battery cell 70 abuts against the first electrical contact 171b and thus establishes a conductive connection with the circuit board 16b; in the fourth position, the battery cell 70 is separated from the first electrical contact 171b and thus disconnects the conductive connection with the circuit board 16b.

[0117] according to Fig.13 As shown in , when the operating element 90b is rotated to the first position, the retaining element 80b and / or the battery cell assembly are in the third position, and the protrusion 91b of the operating element 90b is located at the first end of the spiral groove 811b; and when the operating element 90b is rotated to the second position, the retaining element 80b and / or the battery cell assembly are in the fourth position, and the protrusion 91b of the operating element 90b is located at the second end of the spiral groove 811b. Then, when the protrusion 91b of the operating element 90b is rotated to the first position at the first end of the spiral groove 811b, the user can move the operating element 90b longitudinally to move the protrusion 91b from the spiral groove 811b to the first locking groove 812b so that the operating element 90b is locked in the first position, so that the retaining element 80b and / or the battery cell assembly can no longer be driven to move longitudinally by the rotation operation. Similarly, when the operating element 90b rotates to the second position and the protrusion 91b rotates to the second end of the spiral groove 811b, the user can move the operating element 90b longitudinally to move the protrusion 91b from the spiral groove 811b to the second locking groove 813b to lock the operating element 90b in the second position.

[0118] Similarly, the electronic atomization device 100b may also include elastic elements such as torsion springs to provide elastic force so that the operating element 90b can be moved from an unlocked state to a locked state when it is rotated to the corresponding first position and / or second position, or the operating element 90b is biased toward the locked state.
