[0089] In some embodiments, the connecting member 40 is integrally formed by an injection molding process using an internal slide mold.

[0090] In some embodiments, the internal thread 411 includes two segments 411a, and the two segments 411a are symmetrically distributed relative to the central axis of the connecting hole 41, improving the stability of the threaded connection between the connecting member 40 and the liquid storage bottle 100.

[0091] In some embodiments, the internal thread 411 includes three segments 411a, and the three segments 411a are evenly spaced around the central axis of the connecting hole 41, improving the stability of the threaded connection between the connecting member 40 and the liquid storage bottle 100.

[0092] In some embodiments, the number of the internal threads 411 is two. The two internal threads 411 are spaced along the central axis of the connecting hole 41. It can be understood that the number of the internal threads 411 can be determined according to actual requirements.

[0093] In some embodiments, the internal thread 411 is an internal concave thread, that is, the internal thread 411 is recessed inward relative to the inner surface of the connecting hole 41. Optionally, the internal thread 411 can be an external convex thread, that is, the internal thread 411 protrudes outward relative to the inner surface of the connecting hole 41.

[0094] Please refer to Figure 5 and Figure 6 , the liquid storage bottle 100 is used for storing the aerosol medium. The liquid storage bottle 100 is inserted into the first accommodating cavity 310 through the first opening 30a and is threadedly connected to the connecting member 40. The liquid storage bottle 100 includes a bottle body 10 and a bottle cap 20, and the bottle body 10 is threadedly connected to the connecting member 40. The aerosol medium can be a liquid-shaped e-cigarette liquid, a medical drug, a skin care lotion, an aromatherapy liquid and other media.

[0095] In some embodiments, the bottle body 10 includes a main body portion 11, an opening portion 12, and a handle portion 13. An accommodation cavity is provided in the main body portion 11 for accommodating an aerosol medium. The opening portion 12 is connected to the main body portion 11 and coaxially arranged, and is threadedly connected to the connecting member 40. The opening portion 12 is provided with an opening and a passage communicating the accommodation cavity of the main body portion 11 and the opening of the opening portion 12. The aerosol medium is injected into the main body portion 11 or taken out from the main body portion 11 through the opening portion 12. The handle portion 13 is provided on the bottom wall 11a of the main body portion 11. A user can install the bottle body 10 into the main body 210 of the aerosol device 200 or take out the bottle body 10 from the main body 210 of the aerosol device 200 through the handle portion 13.

[0096] In some embodiments, an external thread 121 is provided on the outer surface of the opening portion 12, and the external thread 121 is used to engage with the internal thread 411 of the connecting member 40. It can be understood that when the internal thread 411 is an internal concave thread, the external thread 121 of the bottle body 10 is an external convex thread; when the internal thread 411 is an external convex thread, the external thread 121 of the bottle body 10 is an internal concave thread.

[0097] In some embodiments, the bottle cap 20 includes a cap body portion 21 and a engaging portion 22 provided on the cap body portion 21. The cap body portion 21 is configured to close the opening of the opening portion 12, and the engaging portion 22 is configured to be engaged with the handle portion 13. When transporting the liquid storage bottle 100, the cap body portion 21 of the bottle cap 20 can close the opening of the opening portion 12, making the liquid storage bottle 100 in a closed state, preventing the aerosol medium in the bottle body 10 from leaking out, which is convenient for transportation. When opening the bottle cap 20 and inserting the bottle body 10 into the main body 210 or taking out the bottle body 10 from the main body 210, the user can engage the engaging portion 22 with the handle portion 13, and then apply a force on the bottle cap 20. The bottle cap 20 conducts the force to the handle portion 13, so as to insert the bottle body 10 into the main body 210 or take out the bottle body 10 from the main body 210. The force-applying area of the bottle cap 20 is larger than the force-applying area of the handle portion 13. In this case, the force-applying area is increased compared with applying force through the handle portion 13, making the disassembly and assembly of the bottle body 10 easier.

[0098] In some embodiments, the handle portion 13 is a convex portion provided on the bottom wall 11a of the main body portion 11, and the convex portion protrudes outward from the bottom wall 11a. The engaging portion 22 is provided with a card slot 22a, and the convex portion is configured to be engaged in the card slot 22a, so as to realize the engaging connection between the handle portion 13 and the engaging portion 22.

[0099] In some embodiments, the engaging portion 22 includes two spaced-apart clamping blocks 221, and the two clamping blocks 221 enclose to form the card slot 22a. The convex portion is configured to be engaged in the card slot 22a. The clamping blocks 221 are semi-circular. The clamping blocks 221 include a mating surface 23, and the mating surfaces 23 of the two clamping blocks 221 cooperate to form the card slot 22a.

[0100] In some embodiments, the shape of the convex portion of the buckling part 13 is a straight line shape, and the mating surface 23 is a flat surface. When the convex portion is engaged with the card slot 22a, the convex portion contacts the entire mating surface 23.

[0101] In some embodiments, the mating surface 23 includes two straight sections 23a and an arc section 23b connected between the two straight sections 23a. The arc section 23b is concave inward in a direction away from the central axis of the liquid storage bottle 100 relative to the straight section 23a. The shape of the convex portion matches the shape of the mating surface 23. The surface of the convex portion includes a straight section for contacting the straight section 23a and an arc section for contacting the arc section 23b. The arc section of the convex portion protrudes outward in a direction away from the central axis of the liquid storage bottle 100 relative to the straight section of the convex portion. When the convex portion is engaged with the card slot 22a, the convex portion contacts the entire mating surface 23.

[0102] In some embodiments, the shape of the convex portion is a straight line shape. The mating surface 23 includes two straight sections 23a and an arc section 23b connected between the two straight sections 23a. The arc section 23b is concave inward in a direction away from the central axis of the liquid storage bottle 100 relative to the straight section 23a. When the convex portion is engaged with the card slot 22a, the straight section 23a contacts the convex portion, that is, the straight section 23a is clamped between the straight sections 23a of the two clamping blocks 221; there is a gap between the arc section 23b and the convex portion, and this gap facilitates the user to remove the bottle cap 20 from the bottle body 10.

[0103] In some embodiments, the clamping block 221 further includes an abutting surface 24, and the abutting surface 24 is configured to abut against the bottom wall 11a of the main body portion 11. When the buckling part 13 is engaged and connected with the engaging part 22, the abutting surface 24 abuts against the bottom wall 11a of the main body portion 11, which is beneficial to improving the stability of the engagement connection between the buckling part 13 and the engaging part 22.

[0104] In some embodiments, the abutting surface 24 is provided with a weight reduction groove 24a. By configuring the weight reduction groove 24a, the overall weight of the bottle cap 20 can be reduced.

[0105] In some embodiments, the buckling part 13 is a concave portion provided on the bottom wall 11a of the main body portion 11, and the concave portion is recessed from the bottom wall 11a. The engaging part 22 includes a clamping block, and the clamping block is configured to be engaged in the concave portion so that the buckling part 13 and the engaging part 22 are engaged and connected.

[0106] In some embodiments, the cover body portion 21 includes a bottom wall 211 and a side wall 212. The bottom wall 211 and the side wall 212 enclose to form a receiving groove 21a, and the receiving groove 21a is used to receive the opening portion 12 to close the opening of the opening portion 12. The engaging part 22 is provided on the bottom wall 211. After the engaging part 22 is engaged and connected with the buckling part 13, the user can hold the side wall 212 of the cover body portion 21 to insert the bottle body 10 into the main body 210 or take out the bottle body 10 from the main body 210.

[0107] In some embodiments, the outer surface of the side wall 212 is provided with a plurality of stripes 2121. By providing the stripes 2121, the frictional force between the user's hand and the side wall 212 can be increased during use. Preferably, the stripes 2121 extend along the length direction of the liquid storage bottle 100, so as to maximize the frictional force between the user's hand and the side wall 212.

[0108] In some embodiments, the cover portion 21 is configured to be partially inserted into the opening portion 12 to close the opening of the opening portion 12.

[0109] In some embodiments, the cover portion 21 is configured to be threadedly connected to the opening portion 12. Optionally, the inner surface of the cover portion 21 is provided with an internal thread that meshes with the external thread 121 of the opening portion 12; alternatively, the inner surface of the opening portion 12 is provided with an internal thread, and the outer surface of the cover portion 21 is provided with an external thread that meshes with the internal thread.

[0110] In some embodiments, when the opening portion 12 of the bottle body 10 is inserted into the first accommodation cavity 310 and connected to the connecting member 40, the bottom wall 11a of the main body portion 11 of the bottle body 10 is flush with the first end 301 at the position where the first opening 30a is located or is located within the first accommodation cavity 310, and the main body portion 11 does not protrude out of the housing 30. When the engaging portion 22 of the bottle cap 20 is engaged and connected to the buckling hand portion 13 of the bottle body 10, at least a part of the bottle cap 20 protrudes out of the housing 30, so that the user can hold the bottle cap 20 and insert the bottle body 10 into the first accommodation cavity 310 and connect it to the connecting member 40.

[0111] Please refer to Figure 7 , when assembling the bottle body 10 and the connecting member 40, the user can insert the bottle body 10 into the first accommodation cavity 310 along the length direction L through the first opening 30a, and then hold the buckling hand portion 13 and rotate the bottle body 10 in the rotational direction R to threadedly connect the opening portion 12 and the connecting member 40; or, the user can connect the bottle cap 20 to the buckling hand portion 13 of the bottle body 10 through the engaging portion 22, and then hold the bottle cap 20 and rotate the bottle body 10 in the rotational direction R to threadedly connect the opening portion 12 and the connecting member 40. When disassembling the bottle body 10 and the connecting member 40, the user can connect the bottle cap 20 to the buckling hand portion 13 of the bottle body 10 through the engaging portion 22, and then hold the bottle cap 20 and rotate the bottle body 10 in the direction opposite to the rotational direction R to disengage the opening portion 12 and the connecting member 40. The rotational direction R can be the clockwise direction or the counterclockwise direction, and this application does not make any restrictions.

[0112] In some embodiments, the main body portion 11 of the bottle body 10 is configured to be inserted into the receiving groove 21a of the bottle cap 20 from the side where the bottom wall 11a of the main body portion 11 is located, so that the bottle cap 20 can be received in the first receiving cavity 31. When the bottle body 10 is received in the first receiving cavity 310 and connected to the connecting member 40, the bottle cap 20 can be inserted into the first receiving cavity 310 from the side where the bottom wall 11a of the main body portion 11 is located and sleeved on the main body portion 11. At least a part of the main body portion 11 is received in the receiving groove 21a, and the bottle cap 20 is received in the first receiving cavity 310 together with the bottle body 10, so that the bottle cap 20 does not need to be placed separately when the aerosol device 200 is in use, improving the usability of the product.

A second receiving cavity 320 is further provided in the housing 30, and the aerosol generating assembly 50 is provided in the second receiving cavity 320. The connecting member 40 is provided with a liquid passage 42, and the liquid passage 42 is used to communicate the second receiving cavity 320 and the opening portion 12, so that the aerosol medium in the bottle body 10 can enter the second receiving cavity 320 through the liquid passage 42. The aerosol generating assembly 50 is used to heat the aerosol medium to generate aerosol. In this embodiment, the first receiving cavity 310 and the second receiving cavity 320 are arranged side by side in a direction perpendicular to the length direction L. In another embodiment, the first receiving cavity 310 and the second receiving cavity 320 are coaxially arranged in the length direction L.

[0114] In some embodiments, a second opening 30b is provided at the second end 302 of the housing 30, and the second opening 30b communicates with the first receiving cavity 310. The connecting member 40 is movably arranged in the first receiving cavity 310 and can move along the length direction L towards the second opening 30b or towards the first opening 30a, and the connecting member 40 can move through the second opening 30b to the outside. The connecting member 40 is configured to communicate or isolate the first receiving cavity 310 and the second receiving cavity 320 when moving along the length direction L, so as to allow or prevent the aerosol medium stored in the liquid storage bottle 100 located in the first receiving cavity 310 from flowing to the aerosol generating assembly 50 located in the second receiving cavity 320. The second receiving cavity 320 is provided with a liquid inlet 321, and the connecting member 40 is configured to communicate or isolate the liquid passage 42 and the liquid inlet 321 when moving along the length direction L.

[0115] The connecting member 40 has a first position state and a second position state. When the connecting member 40 is in the first position state, the bottom wall 11a of the bottle body 10 is flush with the first end 301 at the position of the first opening 30a, and the liquid passage 42 is isolated from the liquid inlet 321; when the connecting member 40 is in the second position state, the bottom wall 11a of the bottle body 10 is spaced apart from the first opening 30a by a preset distance in the length direction L, and the liquid passage 42 is in communication with the liquid inlet 321. In use, the user inserts the bottle body 10 into the first receiving cavity 310 and threadedly connects it to the connecting member 40 to make the connecting member 40 in the first position state.
