At this time, the rotating member 41 drives the traction member 42 to move toward the second end of the shell 1, and the liquid storage tank 51 connected to the traction member 42 moves toward the second end of the shell 1 together with the infusion tube 52. The liquid in the liquid storage tank 51 enters the nozzle 22 through the infusion tube 52 under the action of negative pressure to achieve liquid delivery. When the pressing seat 32 moves to the second position inside the shell 1, the liquid delivery is completed and the pressing seat 32 can stop moving into the shell 1. At this time, the second end of the rotating arm 62 abuts against the rotating member 41 and restricts the rotating member 41 from rotating in the second direction. The rotating member 41 can remain stationary, and the traction member 42, the liquid storage tank 51 and the infusion tube 52 can maintain their positions unchanged.

[0080] Applying pressure to the button 61, the button 61 moves toward the inside of the housing 1, and the second end of the rotating arm 62 moves in a direction away from the rotating member 41. When the button 61 moves to a preset position in the inside of the housing 1, the rotating arm 62 stops restricting the rotating member 41 from rotating in the second direction. At this time, the traction member 42 can move toward the first end of the housing 1, and the traction member 42 drives the liquid storage tank 51 and the infusion tube 52 to move toward the first end of the housing 1, and the liquid in the nozzle 22 is pushed out of the nozzle 22; and the traction member 42 drives the rotating member 41 to rotate in the second direction, and the rotating member 41 drives the guide member 31 to move toward the second end of the housing 1, and the pressing seat 32 connected to the guide member 31 moves toward the second end of the housing 1 synchronously, and the pressing seat 32 can return to the initial position.

[0081] As a possible application scenario, the device can be applied to the field of simulated smoking devices, wherein the liquid storage tank 51 can contain smoke liquid, and the nozzle 22 has an atomization function, and the nozzle 22 can convert the smoke liquid into atomized gas, thereby the device can spray out atomized gas, and the user obtains a smoking experience by inhaling the atomized gas, thereby achieving the purpose of replacing paper cigarettes, and even achieving the purpose of quitting smoking. The device can transfer the smoke liquid in the liquid storage tank 51 to the nozzle 22 by applying pressure to the pressing seat 32, such as pressing the pressing seat 32, and spray the smoke liquid in the nozzle 22 out of the nozzle 22 by applying pressure to the button 61, such as pressing the button 61, that is, the device sprays out atomized gas. The entire device adopts a mechanical structure, does not have electrical components, does not need to be charged, and has a long service life.

The nozzle 22 has a first end and a second end along its length direction, and the second end of the nozzle 22 is inserted into the first through hole 211, so that the nozzle 22 is inserted into the nozzle fixing member 21. In order to facilitate understanding of the specific implementation of the present device, in addition to the technical features of the present device, except for the "housing 1", "rotating arm 62" and the "slope 4141" of the first limiting protrusion 414 on the rotating member 41 to be described below, when the description of "first end" and "second end" is involved, the first end refers to the end close to the first end of the housing 1 (i.e., the end of the housing 1 provided with the nozzle 22), and the second end refers to the end close to the second end of the housing 1 (i.e., the end of the housing 1 provided with the pressing seat 32).

The nozzle 22 is in contact with the hole wall of the first through hole 211 through the positioning protrusions 221, so that the hole diameter of the first through hole 211 can be larger, so that the material used for the nozzle fixing member 21 can be less, and the weight of the nozzle fixing member 21 can be lighter, which is conducive to reducing the weight of the entire device.

[0084] In a specific implementation, a plurality of positioning protrusions 221 form a plurality of positioning protrusion groups, and the plurality of positioning protrusion groups are arranged at intervals along the length direction of the shell 1, so that the nozzle 22 is not easy to shake relative to the length direction of the shell 1 inside the nozzle fixing member 21, and the position of the nozzle 22 inside the nozzle fixing member 21 is relatively stable. Each positioning protrusion group includes at least one positioning protrusion 221. When the positioning protrusion group includes a plurality of positioning protrusions 221, the plurality of positioning protrusions 221 are arranged at intervals around the length direction of the shell 1, so that in the direction around the length direction of the shell 1, the nozzle 22 has a plurality of contact points distributed at intervals with the hole wall of the first through hole 211, which can make the position of the nozzle 22 inside the nozzle fixing member 21 more stable; or, the plurality of positioning protrusions 221 are connected to form an annular structure or a C-shaped structure, so that in the direction around the length direction of the shell 1, the contact area between the nozzle 22 and the hole wall of the first through hole 211 is larger, which can also make the position of the nozzle 22 inside the nozzle fixing member 21 more stable.

[0085] In a specific implementation, the outer wall of the nozzle fixing member 21 is provided with a first positioning shoulder 212, and in the length direction of the housing 1, the projection of the nozzle fixing member 21 is located within the projection range of the first positioning shoulder 212. In the length direction of the housing 1, the projection shape of the first positioning shoulder 212 can be annular.

[0086] Figure 5 , Figure 6 and Figure 7 The schematic diagrams of the structure of the housing of the delivery device provided by the present application are shown respectively. Figure 5 , Figure 6 and Figure 7 As shown, the inner wall of the housing 1 is provided with a positioning groove 1211, and the positioning groove 1211 extends from the first end of the housing 1 to the second end of the housing 1. The first positioning shoulder 212 is located in the positioning groove 1211, and the first positioning shoulder 212 abuts against an end of the positioning groove 1211 away from the first end of the housing 1, so as to limit the movement of the first positioning shoulder 212 toward the second end of the housing 1, that is, to limit the movement of the nozzle fixing member 21 toward the second end of the housing 1.

[0087] In a specific implementation, the outer wall of the nozzle 22 is provided with a second positioning shoulder 222, and in the length direction of the housing 1, the projection of the nozzle 22 is located within the projection range of the second positioning shoulder 222.

The second positioning shoulder 222 is located between the first end of the nozzle 22 and the plurality of positioning protrusions 221 on the outer wall of the nozzle 22, and the second positioning shoulder 222 abuts against the end of the nozzle fixing member 21, specifically, the second positioning shoulder 222 abuts against one end of the nozzle fixing member 21 away from the second end of the housing 1, so as to limit the movement of the second positioning shoulder 222 toward the second end of the housing 1, that is, to limit the movement of the nozzle 22 toward the second end of the housing 1.

[0088] In a possible embodiment, the nozzle structure 2 further includes a nozzle cover 23, which has a first end and a second end along its length direction, the first end of the nozzle cover 23 is provided with an opening 231, the second end of the nozzle cover 23 is fixedly connected to the first end of the shell 1, and the nozzle 22 is located in the opening 231, and the nozzle 22 can be coaxially arranged with the opening 231. In actual use, the atomized gas sprayed by the nozzle 22 can be sprayed out of the nozzle cover 23 through the opening 231. In the direction from the first end of the shell 1 to the second end of the shell 1, the area of ​​the cross section of the nozzle cover 23 in the direction perpendicular to the length direction of the shell 1 gradually increases. In this way, from the second end of the nozzle cover 23 to the first end of the nozzle cover 23, the nozzle cover 23 can be gradually retracted, which is more in line with the user's suction scene.

[0089] In a specific implementation, the second end of the nozzle cover 23 extends into the interior of the housing 1, and the second end of the nozzle cover 23 is located in the positioning groove 1211, and the second end of the nozzle cover 23 abuts against the first positioning shoulder 212, so as to limit the first positioning shoulder 212 from moving toward the first end of the housing 1, thereby limiting the nozzle fixing member 21 from moving toward the first end of the housing 1. In combination with the above, the first positioning shoulder 212 is located between the second end of the nozzle cover 23 and the end of the positioning groove 1211 away from the first end of the housing 1, and the first positioning shoulder 212 abuts against the second end of the nozzle cover 23 and the end of the positioning groove 1211 away from the first end of the housing 1, respectively, and the movement of the first positioning shoulder 212 in the length direction of the housing 1 is limited, thereby limiting the movement of the nozzle fixing member 21 in the length direction of the housing 1, and the position of the nozzle fixing member 21 is fixed.

[0091] Figure 8 FIG. 2 shows an exploded view of the pressing structure of the delivery device provided by the present application. Figure 8 As shown, the outer wall of the guide member 31 is provided with a first sliding structure 311, and the inner wall of the shell 1 is provided with a second sliding structure 13. The first sliding structure 311 and the second sliding structure 13 extend along the length direction of the shell 1 respectively, and the first sliding structure 311 is movably connected with the second sliding structure 13, so that the guide member 31 can move along the length direction of the shell 1 toward the first end of the shell 1 or the second end of the shell 1, and the guide member 31 is restricted from rotating.

[0092] In a specific implementation, one of the first sliding structure 311 and the second sliding structure 13 is a slide rail structure, and the other of the first sliding structure 311 and the second sliding structure 13 is a slide groove structure, and the slide rail structure is movably connected in the slide groove structure. For example, the outer wall of the guide member 31 is provided with a slide rail structure, and the inner wall of the housing 1 is provided with a slide groove structure. In this way, the relative movement of the guide member 31 and the housing 1 can be achieved, and the guide member 31 can be guided, so that the guide member 31 can move along the length direction of the housing 1, and the guide member 31 can be restricted from rotating, and the movement of the guide member 31 is relatively stable.

[0093] In a specific implementation, there can be multiple first sliding structures 311, and multiple first sliding structures 311 are arranged at intervals around the length direction of the housing 1. The number of second sliding structures 13 is the same as that of first sliding structures 311, and one second sliding structure 13 is movably connected to one first sliding structure 311. One first sliding structure 311 cooperates with one second sliding structure 13 to form a sliding assembly, and multiple first sliding structures 311 cooperate with multiple second sliding structures 13 to form multiple sliding assemblies. The guide member 31 and the housing 1 achieve relative movement through multiple sliding assemblies, and the movement of the guide member 31 is more stable.

[0094] In a specific implementation, the guide member 31 has a first end and a second end along its length direction, the first end of the guide member 31 faces the first end of the shell 1, the first end of the guide member 31 is movably connected to the rotating member 41, and the second end of the guide member 31 is inserted into the pressing seat 32. The pressing seat 32 is provided with a mounting hole 321, and the mounting hole 321 extends from the inner wall of the pressing seat 32 to the outer wall of the pressing seat 32. Specifically, the axial direction of the mounting hole 321 can be perpendicular to the length direction of the shell 1, and the mounting hole 321 can be a through hole, that is, the mounting hole 321 extends from the inner wall of the pressing seat 32 to the outer wall of the pressing seat 32. The outer wall of the guide member 31 is provided with a mounting protrusion 312, and the mounting protrusion 312 is located in the mounting hole 321, so as to realize the fixed connection between the guide member 31 and the pressing seat 32.

[0095] In a specific implementation, in the direction from the first end of the housing 1 to the second end of the housing 1, the cross-sectional area of ​​the mounting protrusion 312 on the guide member 31 in the direction perpendicular to the length of the housing 1 gradually decreases. For example, the cross-sectional shape of the mounting protrusion 312 in the direction perpendicular to the length of the housing 1 may be a trapezoid or a triangle. This facilitates the insertion of the guide member 31 into the pressing seat 32 and the entry of the mounting protrusion 312 into the mounting hole 321, making it easier to achieve a fixed connection between the guide member 31 and the pressing seat 32.

[0096] In a specific implementation, there can be multiple mounting holes 321, and the multiple mounting holes 321 are arranged at intervals around the length direction of the housing 1. The number of mounting protrusions 312 is the same as the number of mounting holes 321, and one mounting protrusion 312 is located in one mounting hole 321. One mounting protrusion 312 cooperates with one mounting hole 321 to form a fixing assembly, and multiple mounting protrusions 312 cooperate with multiple mounting holes 321 to form multiple fixing assemblies, so that the fixed connection between the guide member 31 and the pressing seat 32 is more stable.

[0097] In a specific implementation, the second end of the guide member 31 is fixedly connected with a positioning claw 313, and the positioning claw 313 extends along the length direction of the housing 1. The guide member 31 is inserted into the pressing seat 32 through the positioning claw 313. There can be multiple positioning claws 313, and the multiple positioning claws 313 are arranged at intervals around the length direction of the housing 1. The number of positioning claws 313 is the same as that of the mounting protrusions 312, and one mounting protrusion 312 is arranged on one positioning claw 313. The guide member 31 is connected to the pressing seat 32 through the positioning claw 313. The positioning claw 313 can be formed by removing material from the second end of the guide member 31, which can reduce the weight of the guide member 31, and the positioning claw 313 can be deformed to a certain extent in the vertical direction of the length direction of the housing 1, for example, the positioning claw 313 can be tilted toward the central axis of the housing 1, which makes it easier for the guide member 31 to be inserted into the pressing seat 32, and it is also easier for the mounting protrusion 312 to enter the mounting hole 321, so that the fixed connection between the guide member 31 and the pressing seat 32 is easier to achieve.

[0098] In a specific implementation, a clamping member 322 is fixedly connected inside the pressing seat 32, and the clamping member 322 extends along the length direction of the shell 1. There is a storage space between the clamping member 322 and the inner wall of the pressing seat 32. The guide member 31 extends into the storage space, and the inner wall of the guide member 31 abuts against the clamping member 322, and the outer wall of the guide member 31 abuts against the inner wall of the pressing seat 32. Specifically, the positioning claw 313 extends into the storage space, and the side wall of the positioning claw 313 facing the central axis of the shell 1 abuts against the clamping member 322, and the side wall of the positioning claw 313 away from the central axis of the shell 1 abuts against the inner wall of the pressing seat 32. The provision of the clamping member 322 makes the relative position of the guide member 31 and the pressing seat 32 more stable, which can improve the reliability of the fixed connection between the guide member 31 and the pressing seat 32. Specifically, the projection of the clamping member 322 in the length direction of the shell 1 can be annular, and the clamping member 322 and the pressing seat 32 can be coaxially arranged. In the direction surrounding the length direction of the shell 1, the contact area between the clamping member 322 and the guide member 31 is larger, and the clamping member 322 can more significantly improve the reliability of the fixed connection between the guide member 31 and the pressing seat 32.

[0099] As a possible implementation, the rotation axis of the rotating member 41 is parallel to the length direction of the housing 1, and the rotating member 41 has a first end and a second end along its own rotation axis. The first end of the rotating member 41 abuts against the first end of the housing 1, specifically, the first end of the rotating member 41 abuts against the nozzle fixing member 21, so as to limit the movement of the rotating member 41 toward the first end of the housing 1. The guide member 31 is provided with a second through hole 314, the axial direction of the second through hole 314 is parallel to the length direction of the housing 1, and the second end of the rotating member 41 extends into the second through hole 314.

[0100] Fig. 9 FIG. 2 shows a schematic diagram of the structure of the rotating member of the delivery device provided by the present application. Fig. 9 As shown, the rotating member 41 is provided with a third through hole 411, the axial direction of the third through hole 411 is parallel to the length direction of the housing 1, the nozzle fixing member 21 extends into the third through hole 411, and the first end of the rotating member 41 abuts against the first positioning shoulder 212 on the nozzle fixing member 21, so as to limit the movement of the rotating member 41 toward the first end of the housing 1. The infusion tube 52 is provided through the third through hole 411 and the first through hole 211 of the nozzle fixing member 21, and extends into the interior of the nozzle 22.

[0101] In a specific implementation, the outer wall of the rotating member 41 is provided with a first inclined surface 412, the first inclined surface 412 faces the second end of the housing 1, and the first inclined surface 412 extends around the length direction of the housing 1. Along the first direction, the first inclined surface 412 has a first end a and a second end b. The distance between the first end a of the first inclined surface 412 and the first end of the housing 1 is L1, and the distance between the second end b of the first inclined surface 412 and the first end of the housing 1 is L2, wherein L1<L2. That is, compared with the distance between the first end a of the first inclined surface 412 and the first end of the housing 1, the distance between the second end b of the first inclined surface 412 and the first end of the housing 1 is farther.

[0102] The inner wall of the guide member 31 is provided with a second inclined surface 315, the second inclined surface 315 faces the first end of the shell 1, and the second inclined surface 315 extends around the length direction of the shell 1. Along the first direction, the second inclined surface 315 has a first end c and a second end d. The distance between the first end c of the second inclined surface 315 and the first end of the shell 1 is L3, and the distance between the second end d of the second inclined surface 315 and the first end of the shell 1 is L4, wherein L3<L4. That is, compared with the distance between the first end c of the second inclined surface 315 and the first end of the shell 1, the distance between the second end d of the second inclined surface 315 and the first end of the shell 1 is farther. The first inclined surface 412 has a similar inclination direction as the second inclined surface 315.

[0103] The first inclined surface 412 is in contact with the second inclined surface 315. When the guide member 31 moves toward the first end of the housing 1, the second inclined surface 315 moves synchronously with the guide member 31, and the second inclined surface 315 drives the first inclined surface 412 to rotate relatively. The first end c of the second inclined surface 315 is used as the object for motion analysis. The first end c of the second inclined surface 315 moves from the second end b of the first inclined surface 412 to the first end a of the first inclined surface 412. In this way, the first inclined surface 412 is driven to rotate along the first direction, and the rotating member 41 is driven to rotate along the first direction y.

[0104] Fig.10 and Fig.11 The schematic diagrams of the structure of the traction member of the delivery device provided by the present application are shown respectively. Fig.10 and Fig.11 As shown, the traction member 42 is located in the second through hole 314 of the guide member 31, and the traction member 42 is provided with a fourth through hole 421, the axial direction of the fourth through hole 421 is parallel to the length direction of the housing 1, and the second end of the rotating member 41 extends into the fourth through hole 421. The liquid storage tank 51 is located in the second through hole 314 of the guide member 31, and the infusion tube 52 is penetrated through the fourth through hole 421, the third through hole 411 and the first through hole 211 of the nozzle fixing member 21, and extends into the interior of the nozzle 22.

[0105] In a specific implementation, the outer wall of the rotating member 41 is provided with a third inclined surface 413, the third inclined surface 413 faces the second end of the housing 1, the third inclined surface 413 is located between the first inclined surface 412 and the second end of the rotating member 41, and the third inclined surface 413 extends around the length direction of the housing 1. Along the first direction, the third inclined surface 413 has a first end e and a second end f. The distance between the first end e of the third inclined surface 413 and the first end of the housing 1 is L5, and the distance between the second end f of the third inclined surface 413 and the first end of the housing 1 is L6, wherein L5>L6. That is, compared with the distance between the first end e of the third inclined surface 413 and the first end of the housing 1, the distance between the second end f of the third inclined surface 413 and the first end of the housing 1 is closer.

[0106] The inner wall of the traction member 42 is provided with a fourth inclined surface 422, which faces the first end of the housing 1 and extends around the length direction of the housing 1. Along the first direction, the fourth inclined surface 422 has a first end g and a second end h. The distance between the first end g of the fourth inclined surface 422 and the first end of the housing 1 is L7, and the distance between the second end h of the fourth inclined surface 422 and the first end of the housing 1 is L8, wherein L7>L8. That is, compared with the distance between the first end g of the fourth inclined surface 422 and the first end of the housing 1, the distance between the second end h of the fourth inclined surface 422 and the first end of the housing 1 is closer. The third inclined surface 413 and the fourth inclined surface 422 have similar inclination directions, and the inclination direction is opposite to the inclination direction of the first inclined surface 412 or the second inclined surface 315. For example, along the first direction, the first inclined surface 412 and the second inclined surface 315 are inclined toward the second end of the housing 1, and the third inclined surface 413 and the fourth inclined surface 422 are inclined toward the first end of the housing 1.

[0107] The third inclined surface 413 is in contact with the fourth inclined surface 422. In combination with the above, when the guide member 31 moves toward the first end of the housing 1, the rotating member 41 is driven to rotate along the first direction. At this time, the third inclined surface 413 rotates synchronously with the rotating member 41, and the third inclined surface 413 drives the fourth inclined surface 422 to rotate relatively. The first end g of the fourth inclined surface 422 is taken as the object for motion analysis. The first end g of the fourth inclined surface 422 moves from the first end e of the third inclined surface 413 to the second end f of the third inclined surface 413. In this way, the fourth inclined surface 422 is driven to move toward the second end of the housing 1, and the traction member 42 is driven to move toward the second end of the housing 1. Therefore, when the guide member 31 moves toward the first end of the housing 1, the guide member 31 drives the rotating member 41 to rotate along the first direction y, and the rotating member 41 drives the traction member 42 to move toward the second end of the housing 1; conversely, when the traction member 42 moves toward the first end of the housing 1, the traction member 42 drives the rotating member 41 to rotate along the second direction, and the rotating member 41 drives the guide member 31 to move toward the second end of the housing 1.

[0108] In a specific implementation, a third sliding structure 423 is provided on the outer wall of the traction member 42, and a fourth sliding structure 316 is provided on the inner wall of the guide member 31. The third sliding structure 423 and the fourth sliding structure 316 extend along the length direction of the shell 1 respectively, and the third sliding structure 423 is movably connected with the fourth sliding structure 316, so that the traction member 42 can move along the length direction of the shell 1 toward the first end of the shell 1 or the second end of the shell 1, and limit the rotation of the traction member 42.

[0109] In a specific implementation, one of the third sliding structure 423 and the fourth sliding structure 316 is a slide rail structure, and the other of the third sliding structure 423 and the fourth sliding structure 316 is a slide groove structure. The slide rail structure is movably connected in the slide groove structure. For example, the outer wall of the traction member 42 is provided with a slide rail structure, and the inner wall of the guide member 31 is provided with a slide groove structure. In this way, the relative movement of the traction member 42 and the guide member 31 can be achieved, and the traction member 42 can be guided, so that the traction member 42 can move along the length direction of the housing 1, and the rotation of the traction member 42 can be restricted, and the movement of the traction member 42 is relatively stable.

[0110] In a specific implementation, the third sliding structure 423 can be multiple, and the multiple third sliding structures 423 are arranged at intervals around the length direction of the housing 1. The number of the fourth sliding structures 316 is the same as that of the third sliding structures 423, and one fourth sliding structure 316 is movably connected to one third sliding structure 423. One third sliding structure 423 and one fourth sliding structure 316 cooperate to form a sliding assembly, and multiple third sliding structures 423 and multiple fourth sliding structures 316 cooperate to form multiple sliding assemblies. The traction member 42 and the guide member 31 achieve relative movement through multiple sliding assemblies, and the movement of the traction member 42 is more stable. The fourth sliding structure 316 can extend to the positioning claw 313 at the second end of the guide member 31. Specifically, one fourth sliding structure 316 extends to one positioning claw 313.

[0111] In a specific implementation, the outer wall of the rotating member 41 is provided with a first limiting protrusion 414, and the first limiting protrusion 414 includes a slope 4141 and a limiting surface 4142. The slope 4141 faces the inner wall of the shell 1, and along the first direction, the slope 4141 has a first end i and a second end j. The distance between the first end i of the slope 4141 and the central axis of the shell 1 is R1, and the distance between the second end j of the slope 4141 and the central axis of the shell 1 is R2, wherein R1>R2. In other words, compared with the distance between the first end i of the slope 4141 and the central axis of the shell 1, the distance between the second end j of the slope 4141 and the central axis of the shell 1 is closer. The limiting surface 4142 is connected to the first end i of the slope 4141 and the outer wall of the rotating member 41 respectively, and the second end j of the slope 4141 is connected to the outer wall of the rotating member 41.

[0112] Fig.12 The schematic diagram of the button structure of the delivery device provided by the present application is shown. Fig.12 As shown, the second end n of the rotating arm 62 abuts against the first limiting protrusion 414. When the rotating member 41 rotates along the first direction, the abutting position of the second end n of the rotating arm 62 and the first limiting protrusion 414 moves from the second end j of the slope 4141 to the first end i of the slope 4141, and the second end n of the rotating arm 62 gradually moves away from the central axis of the housing 1. It can be understood that the second end n of the rotating arm 62 is gradually lifted by the slope 4141. When the rotating member 41 rotates along the first direction by a preset angle, the abutting position of the second end n of the rotating arm 62 and the first limiting protrusion 414 moves to the limiting surface 4142. It can be understood that the second end n of the rotating arm 62 falls from the slope 4141 and abuts against the limiting surface 4142, so as to limit the rotation of the rotating member 41 along the second direction. Fig.12 The figure shows the situation that the abutting position between the second end n of the rotating arm 62 and the first limiting protrusion 414 moves to the limiting surface 4142. The preset angle may be 30° to 180°, such as 30°, 60°, 90°, 120°, 150° or 180°.

[0113] The rotating arm 62 cooperates with the first limiting protrusion 414 to realize that the rotating member 41 is not restricted from rotating in the first direction, but only restricted from rotating in the second direction. When the button 61 moves to the preset position inside the housing 1, the second end n of the rotating arm 62 leaves the limiting surface 4142 of the first limiting protrusion 414, so that the rotating arm 62 cancels the restriction on the rotating member 41 from rotating in the second direction.

[0114] In a specific implementation, the traction member 42 has a first end and a second end along its length direction, and the first end of the traction member 42 is movably connected to the second end of the rotating member 41. Specifically, the fourth inclined surface 422 on the traction member 42 abuts against the third inclined surface 413 on the rotating member 41, and the traction member 42 and the rotating member 41 can rotate relative to each other, thereby realizing the movably connected first end of the traction member 42 and second end of the rotating member 41.

[0115] Fig.13 FIG. 2 shows a partial structural schematic diagram of the steering structure of the delivery device provided by the present application. Fig.13As shown, the second end of the traction member 42 is provided with a first elastic member 424, the first elastic member 424 is located in the second through hole 314 of the guide member 31, one end of the first elastic member 424 abuts against the second end of the traction member 42, and the other end of the first elastic member 424 is fixedly connected to the housing 1. When the traction member 42 moves toward the second end of the housing 1, the traction member 42 applies pressure to the first elastic member 424. When the traction member 42 moves toward the first end of the housing 1, the first elastic member 424 applies thrust to the traction member 42, that is, the first elastic member 424 can push the traction member 42 to move toward the first end of the housing 1. In actual application, whether the traction member 42 is in a position closer to the first end of the housing 1 or in a position closer to the second end of the housing 1, the first elastic member 424 can apply thrust to the rotating member 41 through the traction member 42, so that the rotating member 41 remains in abutment with the nozzle fixing member 21, thereby limiting the movement of the rotating member 41 along the length direction of the housing 1 and ensuring that the rotating member 41 only rotates.

[0116] In a specific implementation, a limiting ring 14 is provided on the inner wall of the housing 1, and the axial direction of the limiting ring 14 is parallel to the length direction of the housing 1.

[0117] The limiting ring 14 is fixedly connected to the housing 1 through the positioning arm 15. The positioning arm 15 extends along the length direction of the housing 1, one end of the positioning arm 15 is fixedly connected to the limiting ring 14, and the other end of the positioning arm 15 is provided with a second limiting protrusion 151.

[0118] In a specific implementation, there can be multiple positioning arms 15, and the multiple positioning arms 15 are arranged at intervals in the length direction of the housing 1. The number of the limiting grooves 16 is the same as the number of the positioning arms 15, and one second limiting protrusion 151 on one positioning arm 15 is located in one limiting groove 16. The limiting ring 14 is fixedly connected to the housing 1 through the multiple positioning arms 15, so that the fixed connection between the limiting ring 14 and the housing 1 is more stable.

[0119] Fig.14 An exploded view of the liquid storage structure of the delivery device provided by the present application is shown. Fig.14As shown, the liquid storage tank 51 is located in the second through hole 314 of the guide member 31.

Specifically, the mounting groove includes a plurality of mounting pieces 425, the mounting pieces 425 extend along the length direction of the housing 1, one end of the mounting piece 425 is fixedly connected to the second end of the traction member 42, and the other end of the mounting piece 425 faces the second end of the housing 1. The plurality of mounting pieces 425 are arranged at intervals around the length direction of the housing 1, and the plurality of mounting pieces 425 enclose the receiving cavity 4251.

[0121] The end of the traction member 42 facing the second end of the housing 1 is provided with a fifth through hole 426, that is, the second end of the traction member 42 is provided with a fifth through hole 426, and the fifth through hole 426 is communicated with the accommodating cavity 4251, so that the accommodating cavity 4251 can be communicated with the fourth through hole 421 of the traction member 42 through the fifth through hole 426. The infusion tube 52 is penetrated through the fifth through hole 426 and extends into the interior of the nozzle 22. Specifically, the infusion tube 52 is penetrated through the fifth through hole 426, the fourth through hole 421, the third through hole 411 and the first through hole 211 of the nozzle fixing member 21, and extends into the interior of the nozzle 22.

[0122] In a specific implementation, in the vertical direction of the length direction of the housing 1, the size of the accommodating chamber 4251 is r, which can be understood as r being the radial size of the accommodating chamber 4251. In the direction from the second end of the housing 1 to the first end of the housing 1, r gradually increases. For example, the accommodating chamber 4251 can be a frustum. In this way, the liquid storage tank 51 can be prevented from escaping from the accommodating chamber 4251, so that the fixed connection between the liquid storage tank 51 and the traction member 42 is more stable.

[0123] In a specific implementation, the body 512 includes a first portion 5121 and a second portion 5122 connected to each other, and the first portion 5121 is located between the head 511 and the second portion 5122. In the length direction of the housing 1, the projection area of ​​the first portion 5121 is smaller than the projection area of ​​the second portion 5122, which can reduce the space occupied by the body 512 and facilitate the arrangement of the first elastic member 424.

In this way, the volume of the portion of the sleeve 513 located inside the body 512 can be relatively small, and the sleeve 513 can fix the infusion tube 52 while occupying less space inside the liquid storage tank 51, so that the liquid storage tank 51 can accommodate more smoke liquid.

[0126] As a possible implementation, a rotating shaft 17 is fixedly connected inside the housing 1, and the axial direction of the rotating shaft 17 coincides with the rotational axial direction of the rotating arm 62, and the rotating arm 62 is rotationally connected to the housing 1 through the rotating shaft 17.

[0127] In a specific implementation, the projection shape of the rotating arm 62 is an arc in the length direction of the housing 1. When pressure is applied to the button 61, the button 61 drives the rotating arm 62 to rotate, and the first end m of the rotating arm 62 moves toward the direction close to the central axis of the housing 1, and the first end n of the rotating arm 62 can move toward the direction away from the central axis of the housing 1, that is, the first end n of the rotating arm 62 can be lifted, and the first end n of the rotating arm 62 can leave the limiting surface 4142 of the first limiting protrusion 414 on the rotating member 41, so that the restriction of the rotating arm 62 on the rotation of the rotating member 41 in the second direction can be cancelled.

[0128] In a specific implementation, the first end m of the rotating arm 62 is provided with a fifth sliding structure, and the button 61 is provided with a sixth sliding structure. The fifth sliding structure is movably connected with the sixth sliding structure, so that the first end m of the rotating arm 62 can slide relative to the button 61, and the rotating arm 62 can rotate, so that the rotating arm 62 can cancel the restriction on the rotating member 41 to rotate along the second direction. One of the fifth sliding structure and the sixth sliding structure is a pin, and the other of the fifth sliding structure and the sixth sliding structure is a slide groove structure. The pin is movably connected in the slide groove structure, so that the first end m of the rotating arm 62 can slide relative to the button 61. In the rotation axis of the rotating arm 62, the projection of the slide groove structure can be an arc.

[0129] In a specific implementation, a second elastic member is provided on the side of the button 61 facing the inside of the housing 1.

Fig.15 and Fig.16As shown, pressure is applied to the pressing seat 32, and the pressing seat 32 moves from the first position (initial position) to the first end of the housing 1 (the end of the housing 1 provided with the nozzle 22), and the guide member 31 fixedly connected to the pressing seat 32 moves synchronously to the first end of the housing 1. The guide member 31 drives the rotating member 41 to rotate in the first direction, at which time, the rotating member 41 drives the traction member 42 to move toward the second end of the housing 1, and the traction member 42 applies pressure to the first elastic member 424, and the liquid storage tank 51 fixedly connected to the traction member 42 moves together with the liquid infusion tube 52 toward the second end of the housing 1, and the smoke liquid in the liquid storage tank 51 enters the nozzle 22 through the liquid infusion tube 52 under the action of negative pressure, thereby achieving liquid delivery. When the pressing seat 32 moves to the second position inside the shell 1, the liquid delivery is completed and the pressing seat 32 can stop moving into the shell 1. At this time, the second end of the rotating arm 62 abuts against the limiting surface 4142 of the first limiting protrusion 414 on the rotating member 41, and the rotating arm 62 limits the rotating member 41 from rotating in the second direction. The rotating member 41 can remain stationary, and the traction member 42, the liquid storage tank 51 and the infusion tube 52 can maintain their positions unchanged.

[0133] Apply pressure to the button 61, the button 61 moves toward the inside of the housing 1, the button 61 applies pressure to the second elastic member 611, and the second end of the rotating arm 62 moves in a direction away from the rotating member 41. When the button 61 moves to the inside of the housing 1 to a preset position, the second end of the rotating arm 62 leaves the limiting surface 4142 of the first limiting protrusion 414 on the rotating member 41, and the rotating arm 62 stops limiting the rotating member 41 from rotating in the second direction. At this time, the first elastic member 424 pushes the traction member 42 to move toward the first end of the housing 1, and the traction member 42 drives the liquid storage tank 51 together with the infusion tube 52 to move toward the first end of the housing 1, and the smoke liquid in the nozzle 22 is pushed out of the nozzle 22, and the device sprays atomized gas; and the traction member 42 drives the rotating member 41 to rotate in the second direction, and the rotating member 41 drives the guide member 31 to move toward the second end of the housing 1, and the pressing seat 32 fixedly connected to the guide member 31 moves toward the second end of the housing 1 synchronously, and the pressing seat 32 can return to the initial position. After the pressure on the button 61 disappears, the second elastic member 611 pushes the button 61 to return to its original position.
