Referring to fig. 1-2, in one embodiment of the present invention, an inhalation device 100 is provided for atomizing an aerosol-generating substrate to form an aerosol for inhalation by a user.

The inhalation device 100 comprises an atomization body 10 and a protective shell 30, wherein the atomization body 10 comprises a shell assembly 12, a rotating member 14 and a liquid storage bottle assembly 16, the rotating member 14 is sleeved outside the liquid storage bottle assembly 16 and is connected with the shell assembly 12, and the protective shell 30 is sleeved outside the rotating member 14 so as to cover and protect the rotating member 14 and the liquid storage bottle assembly 16. When the user rotates the protective housing 30, the rotating member 14 is driven to rotate, and the liquid storage bottle assembly 16 is driven by the rotating member 14 to rotate relative to the housing assembly 12 and move along the axial direction of the housing assembly 12 toward the direction close to the bottom of the protective housing, so that the liquid storage bottle assembly 16 moves away from the housing assembly 12, the pressure inside the spraying member 123 in the housing assembly 12 is reduced, and the aerosol generating substrate in the liquid storage bottle assembly 16 flows into the spraying member 123 in the housing assembly 12 under the action of the pressure difference, so that the subsequent atomization spraying is facilitated.

Referring to fig. 2-3, specifically, the housing assembly 12 and the reservoir assembly 16 respectively have a first spiral surface 121 and a second spiral surface 162 facing each other, and the reservoir assembly 16 and the housing assembly 12 are guided by the cooperation of the first spiral surface 121 and the second spiral surface 162 to relatively rotate and move in a direction away from each other along the axial direction of the housing assembly 12, which is equivalent to converting the rotational movement between the reservoir assembly 16 and the housing assembly 12 into the lifting movement along the axial direction of the housing assembly 12 by the cooperation of the first spiral surface 121 and the second spiral surface 162, so that the reservoir assembly 16 can move in a direction away from the housing assembly 12 while rotating relative to the housing assembly 12, thereby reducing the internal pressure of the spraying member 123 in the housing assembly 12, and further enabling the aerosol generating substrate in the reservoir assembly 16 to enter the spraying member 123 under the action of the pressure difference, so as to prepare for the subsequent spraying atomization.

Further, the liquid storage bottle assembly 16 comprises a clamping ring 161 and a liquid suction tube 163, wherein the clamping ring 161 is matched with the shell assembly 12 and is used for installing the liquid storage bottle 17, one end of the liquid suction tube 163 is movably arranged in the spraying piece 123, and the other end of the liquid suction tube 163 is used for being inserted into the liquid storage bottle 17. In use, the protective shell 30 is opened and then the reservoir 17 is mounted to the collar 161 with the pipette 163 inserted into the reservoir 17. Then, when the user rotates the protective housing 30, the rotating member 14 drives the snap ring 161 to rotate relative to the housing assembly 12, and meanwhile, the snap ring 161 drives the liquid storage bottle 17 and the liquid suction tube 163 to synchronously move in a direction away from the housing assembly 12, so that the liquid suction tube 163 moves in the spraying member 123, the space in the spraying member 123 is increased, the pressure in the spraying member 123 is reduced, and aerosol in the liquid storage bottle 17 flows into the spraying member 123 through the liquid suction tube 163.

Wherein the reservoir 17 is detachably mounted on the collar 161, and after the aerosol-generating substrate in the current reservoir 17 is used, another reservoir 17 may be replaced and mounted on the collar 161. Specifically, during the assembly process, the liquid storage bottle 17 is sleeved on the clamping ring 161, and meanwhile, the liquid suction pipe 163 punctures the sealing cover of the liquid storage bottle 17 and stretches into the liquid storage bottle 17, so that the aerosol generating substrate in the liquid storage bottle 17 can be sucked into the spraying piece 123 by using the liquid suction pipe 163.

Further, the inhalation device 100 further includes a first elastic member 40, where the first elastic member 40 abuts between the liquid storage bottle assembly 16 and the rotating member 14 along the axial direction of the housing assembly 12, and the first elastic member 40 stores elastic potential energy when the liquid storage bottle assembly 16 moves in a direction approaching the bottom of the protective housing 30, that is, when the liquid storage bottle assembly 16 moves in a direction approaching the bottom of the protective housing 30, the first elastic member 40 is compressed, and stores elastic potential energy that drives the liquid storage bottle assembly 16 to move away from the bottom of the protective housing 30. And, when the first elastic member 40 releases the stored elastic potential energy, the liquid storage bottle assembly 16 moves away from the bottom of the protective shell 30 along the axial direction of the shell assembly 12, and causes the shell assembly 12 to spray the aerosol outwards, that is, the shell assembly 12 moves towards the shell assembly 12, and the liquid storage bottle assembly 16 presses the aerosol generating substrate in the spray member 123 in the shell assembly 12 outwards, so as to form the aerosol sprayed outwards for inhalation by a user.

Specifically, when the liquid storage bottle assembly 16 is moved in a direction approaching the housing assembly 12, the liquid suction pipe 163 is moved in a direction approaching the ejection member 123, compressing the space inside the ejection member 123, and the aerosol-generating substrate sucked into the ejection member 123 in the early stage is extruded and ejected to form an aerosol for inhalation by the user. And, be provided with the check valve in the pipette 163, the check valve only allows liquid to flow to the sparging piece 123 from the stock solution bottle 17, and when the pipette 163 moves to being close to the stock solution bottle 17, the check valve stops aerosol generating substrate backward flow, guarantees that aerosol generating substrate effectively atomizes and sprays.

Referring to fig. 1 and 3-4, in some embodiments, the inhalation device 100 further includes a locking assembly 80, wherein the locking assembly 80 is movably sleeved on the housing assembly 12 along the radial direction of the housing assembly 12, and is used for locking the liquid storage bottle assembly 16 after moving away from the housing assembly 12, that is, when the user rotates the protective shell 30 once, the liquid storage bottle assembly 16 moves away from the housing assembly 12 and is locked by the locking assembly 80, so that the first elastic member 40 keeps in a compressed state to store elastic potential energy. After that, the user presses the locking assembly 80, so that the locking assembly 80 releases the locking of the liquid storage bottle assembly 16, and the liquid storage bottle assembly 16 can move towards the housing assembly 12 under the action of the first elastic member 40, thereby completing one atomization injection.

Specifically, when the reservoir assembly 16 is moved away from the housing assembly 12, the locking assembly 80 abuts against the top of the collar 161, thereby blocking the collar 161 from rising and locking the reservoir assembly 16. When unlocking is required, a pushing force along the radial direction of the shell assembly 12 is applied to the locking assembly 80, so that the locking assembly 80 is dislocated with the clamping ring 161 (as shown in fig. 4), and the clamping ring 161 is further allowed to move towards the shell assembly 12 under the action of the first elastic piece 40, so that atomization injection is realized.

Equivalently, the counting mechanism 50 is disposed on the liquid storage bottle assembly 16 or the protective shell 30 through the fixing shell 52, and when the bottom of the liquid storage bottle assembly 16 and the bottom of the protective shell 30 are close to each other, the trigger member 70 contacts with the transmission assembly 56, so that the transmission assembly 56 drives the counting ring 54 to rotate under the action of the trigger member 70, and one-time counting is realized.

Specifically, the fixed shell 52 is provided with an indicating portion 521, the counting ring 54 is provided with a plurality of scale marks arranged along the circumferential direction, and when the transmission assembly 56 is driven to rotate by the action of the trigger piece 70, the indicating portion 521 points to different scale marks, so that the indicating portion 521 indicates the jumping of the scale marks, and further the counting function is realized.

Specifically, a plurality of consecutive numbers, for example, 0-60, are arranged on the outer peripheral surface of the counting ring 54, and the number of the numbers pointed by the indication part 521 gradually decreases along with the rotation of the counting ring 54, so as to intuitively display the remaining usage times of the aerosol-generating substrate in the liquid storage bottle 17, so that a user can conveniently know the usage condition of the aerosol-generating substrate in the liquid storage bottle 17, and when the indication part 521 points to zero on the counting ring 54, the indication part 521 indicates that the liquid storage bottle 17 is empty and the liquid storage bottle 17 needs to be replaced. It will be appreciated that in other embodiments, as the counting ring 54 rotates, the number of the numbers pointed by the indication portion 521 increases gradually to visually display the number of times of atomization, and the number of times of atomization that has been used or the number of times of atomization that remains is not limited herein.

Further, the fixed case 52 is provided with a viewing hole 523, the indication portion 521 is disposed at the edge of the viewing hole 523, and at least a portion of the scale marks are exposed at the viewing hole 523, so as to display the scale marks on the counting ring 54 through the viewing hole 523, and further display the current count. Optionally, the protective housing 30 is transparent, and the user can see the window 523 in the inner stationary housing 52 through the protective housing 30, and thus the current count.

In some embodiments, a movable space is reserved between the bottom of the protective housing 30 and the bottom of the liquid storage bottle 17, the counting mechanism 50 is detachably connected to the bottom of the liquid storage bottle 17, and the bottom of the protective housing 30 is provided with a trigger member 70 facing the counting mechanism 50, so that when the liquid storage bottle 17 moves relative to the bottom of the protective housing 30, the trigger member 70 can be contacted with or separated from the counting mechanism 50. It will be appreciated that in other embodiments, the counting mechanism 50 is disposed at the bottom of the protective housing 30, the trigger member 70 is detachably disposed at the bottom of the liquid storage bottle 17, and the positions of the counting mechanism 50 and the trigger member 70 may be exchanged.

In some embodiments, the transmission assembly 56 includes an actuating member 561 and a toggle member 563, the actuating member 561 is movably disposed in the fixed housing 52 along a radial direction of the fixed housing 52, the toggle member 563 is swingably disposed on the fixed housing 52, and one end of the toggle member 563 is connected to the actuating member 561, and the other end abuts against the counting ring 54. When the actuating member 561 contacts with and separates from the trigger member 70, the actuating member 561 moves along the radial direction of the fixed housing 52 and drives the poking member 563 to swing reciprocally, so as to poke the counting ring 54 to rotate intermittently in one direction and count correspondingly. When the user rotates the protective housing 30, the liquid storage bottle assembly 16 moves towards the direction close to the bottom of the protective housing 30, so that the counting mechanism 50 and the trigger piece 70 are close to each other, the trigger piece 70 can be abutted against the actuating piece 561 in the counting mechanism 50, and pushes the actuating piece 561 to move along the radial direction of the fixed shell 52, so as to pull the poking piece 563 to swing, and the poking piece 563 pushes the counting ring 54 to rotate once, so that one counting is realized, the intermittent rotation of the counting ring 54 is repeated, and the statistics of the atomization using times is realized.

Specifically, a plurality of ratchet teeth 541 are circumferentially arranged on the inner wall of the counting ring 54, the stirring member 563 is abutted against any one of the plurality of ratchet teeth 541, and when the stirring member 563 swings reciprocally, the swinging member pushes the counting ring 54 to rotate and then abuts against the following ratchet tooth 541 through the current ratchet teeth 541, so that the user rotates the protective shell 30 once, and the swinging member swings reciprocally and pushes the counting ring 54 to rotate once, thereby realizing corresponding counting. Equivalently, the toggle member 563 and the counting ring 54 are formed into a ratchet-pawl structure to perform counting. Optionally, the stirring member 563 is swingably disposed around the central axis of the counting ring 54, and the swinging direction of the stirring member 563 is tangential to the counting ring 54, so as to push the counting ring 54 to rotate around itself axially.

Further, the fixing case 52 is provided with a through hole 53, and as the protective case 30 and the liquid storage bottle assembly 16 approach to and separate from each other, the trigger member 70 extends into and retreats from the through hole 53, and the trigger member 561 drives the toggle member 563 to swing, so that the trigger member 70 is allowed to contact and separate from the trigger member 561 by providing the through hole 53 on the fixing case 52, and the function of triggering the counting mechanism 50 by the trigger member 70 is further realized.

Specifically, the operating member 561 has an operating surface 562 facing the through hole 53 for abutment with the trigger member 70, and in a direction in which the operating surface 562 points to the trigger member 70, the operating surface 562 is configured to incline from inside to outside, and when the trigger member 70 abuts against the operating surface 562, the operating member 561 can be moved outwardly in a radial direction of the fixed case 52 by the outwardly inclined operating surface 562, so that the operating member 561 pulls the toggle member 563 to swing.

In some embodiments, the transmission assembly 56 further includes a second elastic member 567, where the second elastic member 567 abuts between the actuating member 561 and the fixed housing 52 along a radial direction of the fixed housing 52, for storing elastic potential energy for restoring the actuating member 561 when the actuating member 561 is pushed by the trigger member 70. That is, when the trigger 70 is moved close to the operating member 561 and pushes the operating member 561, the second elastic member 567 is compressed, and when the trigger 70 is moved away from the operating member 561, the second elastic member 567 pushes the trigger 70 to be restored, so that the trigger 70 reciprocates in the radial direction of the fixed housing 52, thereby pushing the toggle member 563 to reciprocate to intermittently rotate the counter ring 54 in one direction.

In some embodiments, the poking part 563 includes a mounting part 564 and a poking ring 566 which are connected to each other, the mounting part 564 is rotatably sleeved on the fixed shell 52, a sliding groove 565 is formed in the mounting part 564 along a direction intersecting with a moving direction of the actuating part 561, the actuating part 561 has a protrusion 60 slidably disposed in the sliding groove 565, and the poking ring 566 is driven to swing reciprocally when the protrusion 60 slides reciprocally in the sliding groove 565 under the actuation of the trigger part 70. When the boss 60 and the actuator 561 move in a certain radial direction of the fixed case 52, the boss 60 abuts against the inner wall of the slide groove 565 in the direction in which the actuator 561 moves, and pulls the dial 566 to swing.

After the protrusion 60 applies a force to the stirring member 563 along the moving direction of the actuating member 561, the component force of the force drives the stirring member 563 to swing, and in order to prevent the swinging stirring member 563 from interfering with the protrusion 60 moving linearly, a sliding groove 565 intersecting with the moving direction of the actuating member 561 is formed on the mounting portion 564, and the actuating member 561 moves linearly through the protrusion 60 to push the stirring member 563 to swing, and at the same time, the protrusion 60 can slide relative to the sliding groove 565, so that the stirring member 563 and the protrusion 60 can be prevented from interfering. Alternatively, the extending direction of the sliding grooves 565 is perpendicular to the moving direction of the operating member 561.

Further, along the rotation direction of the counting ring 54, the ratchet teeth 541 have a first tooth surface 543 located at the upstream of rotation and a second tooth surface 545 located at the downstream of rotation and intersecting with the first tooth surface 543, and one end of the toggle ring 566 abuts against the side of the ratchet teeth 541 having the first tooth surface 543, so that a toggle force directed to the second tooth surface 545 by the first tooth surface 543 can be applied to the counting ring 54, thereby pushing the counting ring 54 to intermittently rotate unidirectionally along the direction from the first tooth surface 543 to the second tooth surface 545, so as to convert the radial linear motion of the actuator 561 into the circumferential rotational motion of the counting ring 54.

In some embodiments, a rotation stopping elastic sheet 57 is disposed on the fixed housing 52, the rotation stopping elastic sheet 57 elastically abuts against the counting ring 54, only allows the counting ring 54 to rotate unidirectionally, and when the toggle member 563 swings reversely, the rotation stopping elastic sheet 57 abuts against the counting ring 54, so as to prevent the counting ring 54 from being reversely rotated by the toggle member 563.

Further, in the rotation direction of the counter ring 54, the ratchet tooth 541 has a first tooth surface 543 located at the upstream of rotation and a second tooth surface 545 located at the downstream of rotation and intersecting the first tooth surface 543, and one end of the rotation stop spring 57 abuts against the side of the ratchet tooth 541 having the first tooth surface 543, so that a blocking force directed from the first tooth surface 543 to the second tooth surface 545 can be applied to the counter ring 54, preventing the counter ring 54 from reversing in the direction from the second tooth surface 545 to the first tooth surface 543.

The inhalation device 100 is operated by first rotating the protective housing 30 and driving the rotating member 14 to rotate, then driving the liquid storage bottle assembly 16 to rotate and descend in a direction approaching the bottom of the protective housing 30, inhaling the aerosol-generating substrate in the liquid storage bottle assembly 16 into the spraying member 123, compressing the first elastic member 40, simultaneously contacting the trigger member 70 with the counting mechanism 50 for counting once, and locking the snap ring 161 in the liquid storage bottle assembly 16 by the locking assembly 80. After that, the user presses the locking assembly 80 to release the locked liquid storage bottle assembly 16 from the locking assembly 80, and the liquid storage bottle assembly 16 can move away from the bottom of the protective shell 30 and towards the direction close to the shell assembly 12 under the action of the first elastic member 40, so as to push and atomize the aerosol-generating substrate stored in the spraying member 123, thereby completing one atomization use. In this way, the above operation is repeated, and the aerosol-generating substrate in the liquid storage bottle 17 is continuously atomized and used.
