The present invention relates to aerosol forming field, and more specifically, to an aerosol forming device.
A heat-not-burn device is an aerosol forming device that heats an aerosol forming material in a low-temperature heat-not-burn manner to form inhalable aerosol. Currently, in the heat-not-burn device, a heater like a heating sheet is usually inserted into an aerosol forming substrate to perform heating, and a heating temperature is controlled to volatilize components in the aerosol forming substrate to generate aerosol for inhalation by a person.
The aerosol forming substrate tends to become sticky after heating and forms a residue on the heater. This affects a heating effect during use by the heater a next time. For example, a burning smell is generated. Therefore, after the heater has been used for a period of time, it is necessary to clean the heater or replace a new heater.
In an embodiment, the present invention provides an aerosol forming device, comprising: a shell formed with an accommodating cavity at an end; a heating assembly detachably accommodated in the accommodating cavity; and an elastic mechanism disposed in the shell, wherein the heating assembly is formed with a heating cavity configured to accommodate an aerosol forming substrate, wherein the elastic mechanism has a locked position and a released position, and wherein, when the elastic mechanism is switched from the locked position to the released position, the elastic mechanism is configured to push the heating assembly to move toward an opening of the accommodating cavity.

As shown in
An accommodating cavity 100 is formed at an upper end of the shell 10, an opening 101 is defined in a top portion of the accommodating cavity 100, and the upper cover assembly 20 and the heating assembly 30 are both detachably accommodated in the accommodating cavity 100. An insertion hole 210 for inserting the aerosol forming substrate 9 is formed in the upper cover assembly 20, a heating cavity 310 used for accommodating the aerosol forming substrate 9 is formed in the heating assembly 30, and the aerosol forming substrate 9 may be inserted into the heating cavity 310 through the insertion hole 210. After the heating assembly 30 is energized to generate heat, heat may be transferred to the aerosol forming substrate 9, to implement heating of the aerosol forming substrate 9. A heating manner of the heating assembly 30 is not limited. For example, the heating manner may be resistive heating, electromagnetic heating, infrared radiation heating, chemical heating, or the like.
The upper cover assembly 20 is detachably mounted in the accommodating cavity 100, and is slidable back and forth between a first position and a second position. The upper cover assembly 20 includes an upper cover 21 vertically slidably disposed in the accommodating cavity 100 and a dust cover 22 horizontally slidably disposed on an upper side of the upper cover 21. The insertion hole 210 is formed longitudinally penetrating the upper cover 21. A shape and a size of the insertion hole 210 may adapt to the aerosol forming substrate 9. When the upper cover assembly 20 is at the first position, the upper cover 21 is accommodated in the accommodating cavity 100. When the upper cover assembly 20 is at the second position, the upper cover 21 is at least partially exposed from the accommodating cavity 100. In this case, the upper cover assembly 20 may be pulled out of the accommodating cavity 100.
The dust cover 22 is configured to block or expose the insertion hole 210. When the aerosol forming device 1 does not need to be used, the dust cover 22 may be pushed to block the insertion hole 210, to keep dust from entering the insertion hole 210. When the device needs to be used, the dust cover 22 may be pushed to expose the insertion hole 210, to facilitate the insertion of the aerosol forming substrate 9 through the insertion hole 210.
As shown in
The heating assembly 30 may include a heating tube 31, a base 33 disposed at a bottom of the heating tube 31, and a heating element 32 disposed at the base 33. The heating tube 31 is tube-shaped, and an inner wall surface of the heating tube defines the heating cavity 310 used for accommodating the aerosol forming substrate 9. The inner wall surface of the heating tube 31 may protrude inward to form an annular protrusion 315. When the aerosol forming substrate 9 is accommodated in the heating cavity 310, a lower end surface of the aerosol forming substrate 9 may be pressed against an upper end surface of the annular protrusion 315. A limiting flange 313 fitting the positioning portion 211 may be formed on an outer-wall surface of an upper end of the heating tube 31. The limiting flange 313 may be pressed by the positioning portion 211 to push the heating assembly 30 to move downward, and may be pushed by a sliding member 40 to push the heating assembly 30 to move upward. In some embodiments, the limiting flange 313 may be annular and formed by the outer-wall surface of the upper end of the heating tube 31 protruding outward in a radial direction. A lower end surface of the positioning portion 211 may be pressed against the limiting flange 313 to press the upper cover assembly 20 downward and may push the heating assembly 30 to move downward in a direction away from the opening 101 of the accommodating cavity 100. In other embodiments, the positioning portion 211 may be pressed against the upper end of the heating tube 31 surface, so that the limiting flange 313 may not be disposed on the heating tube 31.
In some embodiments, an inner surface of a cavity wall of the heating cavity 310 may further protrude inwardly to form at least two airway ribs 311. Each airway rib 311 extends in an axial direction of the heating cavity 310. After the aerosol forming substrate 9 is accommodated in the heating cavity 310, an outer surface of the aerosol forming substrate 9 may be pressed against at least one group of two airway ribs 311. An airway 312 for a gas to flow through may be formed between the outer surface of the aerosol forming substrate 9 and the at least one group of two airway ribs 311. Specifically, a gap is formed between the outer surface of the aerosol forming substrate 9 and the inner surface of the cavity wall of the heating cavity 310 between the at least one group of two airway ribs 311. The gap forms the airway 312. In this way, it can be ensured that an airflow flows smoothly during inhalation. Preferably, a plurality of airway ribs 311 are provided. The plurality of airway ribs 311 may be distributed at equal intervals in a circumferential direction of the heating cavity 310. In some embodiments, the number of the airway ribs 311 ranges from 6 to 12. One airway 312 is formed between the outer surface of the aerosol forming substrate 9 and each of every two adjacent airway ribs 311, so that an airflow can flow more smoothly during inhalation.
In some embodiments, inner contours of the plurality of airway ribs 311 in a same horizontal cross-section are located at a same circumference. The heating cavity 310 has a first end and a second end that are disposed opposite in the axial direction. The first end has a cavity opening 3101 and is used for inserting the aerosol forming substrate 9. That is, the first end is an end close to the upper cover assembly 20, and the second end is an end close to the base 33. Diameters of circles defined by inner contours of the plurality of airway ribs 311 in same horizontal cross-sections in a direction from the first end to the second end may gradually decrease. In this way, a guide effect during the insertion of the aerosol forming substrate 9 may be formed. In this embodiment, each airway rib 311 may include a first rib section 3111 and a second rib section 3112 connected to a lower end of the first rib section 3111 in an axial direction. The first rib section 3111 and the second rib section 3112 may have different slope angles. A slope angle α of the first rib section 3111 may be greater than or equal to a slope angle β of the second rib section 3112. In some embodiments, the slope angle α of the first rib section 3111 may range from 10 degrees to 40 degrees, and the slope angle β of the second rib section 3112 may range from 1 degree to 10 degrees. The slope angle of the first rib section 3111 located above is large, so that quick feeding of the aerosol forming substrate 9 can be facilitated. The slope angle of the second rib section 3112 located below is small, so that circumferential positioning of the aerosol forming substrate 9 can be implemented, and the airway 312 for a gas to flow is formed. In other embodiments, each airway rib 311 may be formed by at least three rib sections sequentially connected in the axial direction. The at least three rib sections may have different slope angles. The slope angle of one rib section located above may be greater than or equal to the slope angle of one rib section located below the rib section.
As shown in
The heating element 32 may be a sheet or a pillar. A lower end of the heating element 32 may be inserted in the base 33 for fastening. An upper end of the heating element 32 is accommodated in the heating cavity 310 and may be inserted into the aerosol forming substrate 9 to heat the aerosol forming substrate 9. In this embodiment, the heating element 32 may be cylindrical and may have a conical tip portion 321. The conical tip portion 321 may facilitate the insertion into the aerosol forming substrate 9. Because the heating element 32 is cylindrical, after the aerosol forming substrate 9 is heated, the aerosol forming substrate 9 may be manually rotated, to separate the aerosol forming substrate 9 from a sticky part after the heating of the heating element 32 and then pull out the aerosol forming substrate 9.

In some embodiments, the elastic mechanism 50 may include a first elastic assembly 51 and a second elastic assembly 52 that fit each other. The first elastic assembly 51 is supported below the sliding member 40, and can push the sliding member 40 to move upward, and may be pressed by the sliding member 40 to move downward. The first elastic assembly 51 may include a push rod 511 vertically movably disposed in the shell 10 and a first elastic member 512 connected to the push rod 511. The second elastic assembly 52 is configured to lock or release the first elastic assembly 51, and may include a locking member 521 transversely movably disposed in the shell 10 and a second elastic member 523 connected to the locking member 521. A first clamp portion 5114 and a second clamp portion 5213 that are in snap-fit with each other may be respectively formed on the push rod 511 and the locking member 521. The first clamp portion 5114 and the second clamp portion 5213 are engaged with or disengaged from each other, to implement locking or release of the first elastic assembly 51. When the push rod 511 and the locking member 521 are clamped to each other, an upper end surface of the first clamp portion 5114 abuts against a lower end surface of the second clamp portion 5213 under the action of elastic forces of the first elastic member 512 and the second elastic member 523, to lock the first elastic assembly 51. When the locking member 521 moves inward transversely under the action of an external force, the second clamp portion 5213 moves inward transversely to be disengaged from the first clamp portion 5114, to release locking of the first elastic assembly 51. The push rod 511 moves upward under the action of the elastic force of the first elastic member 512, and pushes the sliding member 40 to move, to push the upper cover assembly 20 and the heating assembly 30 to move.
Specifically, the first elastic assembly 51 and the second elastic assembly 52 may be mounted in the bracket assembly 60. The bracket assembly 60 may include a first bracket 61 and a second bracket 62 that are mounted fitting each other. The battery 70 and the circuit board 80 may both be accommodated between the first bracket 61 and the second bracket 62. A support member 66 may further be fixedly mounted in the bracket assembly 60, and configured to support the push rod 511 and the first elastic member 512. The push rod 511 may be vertically slidably disposed in the bracket assembly 60, and may include a first rod section 5111, a second rod section 5112, and a third rod section 5113 that are sequentially connected from top to bottom in an axial direction. An external cross-sectional size of the second rod section 5112 is greater than external cross-sectional sizes of the first rod section 5111 and the third rod section 5113. The bracket assembly 60 has a top wall 63. A through hole 64 for the first rod section 5111 to slidably pass through is opened in the top wall 63. A cross-sectional shape and a cross-sectional size of the through hole 64 may adapt to a cross-sectional shape and a cross-sectional size of the first rod section 5111. The first rod section 5111 passes through the through hole 64 and is pressed against a bottom wall of the sliding member 40, so that the sliding member 40 can be pushed to move upward.
The third rod section 5113 may be cylindrical, and a lower end of the third rod section 5113 may be vertically slidably sleeved in the support member 66. The first elastic member 512 may be a pillar-shaped spring and sleeved on the third rod section 5113, an upper end of the first elastic member 512 may be pressed against a lower end surface of the second rod section 5112, and a lower end of the first elastic member 512 may be pressed against an upper end surface of the support member 66. The first elastic member 512 has a compressed state and a released state. When the elastic mechanism 50 is in the locked position, the first elastic member 512 is in the compressed state. When the elastic mechanism 50 is switched from the locked position to the released position, a length of the first elastic member 512 increases to generate an elastic restoring force. The elastic restoring force acts on the push rod 511 to make the push rod move upward. In other embodiments, the first elastic member 512 may be a coil spring, an elastic sheet, a torsional spring, or another structure that can generate an elastic deformation, and the elastic deformation is generated to generate the elastic restoring force. The elastic restoring force acts on the push rod 511 to make the push rod move upward.
The first clamp portion 5114 may be formed on the second rod section 5112. The second rod section 5112 may be approximately a rectangular pillar. A side of the second rod section 5112 toward the locking member 521 may concave inward to form a slot 5115, so that interference between the second rod section 5112 and the locking member 521 can be avoided. The inner wall surface of the slot 5115 protrudes inward to form the first clamp portion 5114.
A press key 11 may be disposed on the shell 10 corresponding to the second elastic assembly 52. The press key 11 and the display 12 may be respectively disposed on two sides of the shell 10. When the press key 11 is pressed by an external force, the locking member 521 can be pushed to move inward transversely. After pressing is released, the locking member 521 and the press key 11 can move transversely outward and restore under the action of the elastic force of the second elastic member 523. The locking member 521 may include a main body portion 5211 and the second clamp portion 5213 formed by a side of the main body portion 5211 extending outward. The main body portion 5211 may be a rectangular tube. A side of the main body portion 5211 toward the press key 11 extends inward transversely to form a mounting hole 5212, used for mounting the second elastic member 523. A first guide slope 5116 and a second guide slope 5214 may further be respectively formed at a lower end surface of the first clamp portion 5114 and an upper end surface of the second clamp portion 5213. When the push rod 511 is pressed down, through the fitting of the first guide slope 5116 and the second guide slope 5214, the locking member 521 may be pushed to move inward transversely, so that the first clamp portion 5114 can move downward below the second clamp portion 5213 to be engaged with the second clamp portion 5213.
The second elastic assembly 52 may further include a mounting member 52 fixedly mounted in the bracket assembly 60. The mounting member 52 may be a sheet and used for limiting the second elastic member 523. The second elastic member 523 may be a spring and may be disposed in the mounting hole 5212. One end of the second elastic member 523 may be pressed against a hole bottom wall of the mounting hole 5212, and the other end may be pressed against the mounting member 52.
The sliding member 40 may be approximately an elliptic cylinder. The sliding member 40 is slidably mounted in the shell 10, and may slide back and forth between the first position and the second position. An accommodating hole 41 may further be formed longitudinally penetrating the sliding member 40, and the heating assembly 30 is sleeved inside the accommodating hole 41. A limiting structure may further be disposed in the sliding member 40, to limit a maximum upward movement position of the sliding member 40, to keep the sliding member 40 from being detached from the shell 10. The limiting structure may be fastened to the bracket assembly 60, and may include a limiting pillar 65 longitudinally slidably disposed in the sliding member 40 and a limiting member 45 extending transversely out of the limiting pillar 65. The limiting pillar 65 may be formed by the top wall 63 of the bracket assembly 60 extending upward. The limiting member 45 may be approximately a transversely disposed sheet, and may be fixedly mounted on a side of a top end of the limiting pillar 65.
The sliding member 40 may be pressed and mounted below the upper cover 21, and may be magnetically connected to the upper cover 21. When the sliding member 40 and the upper cover assembly 20 are at the second position, the upper cover assembly 20 is only partially exposed from the accommodating cavity 100 of the shell 10, and the upper cover assembly 20 is magnetically attracted to the sliding member 40 and kept from being popped from the accommodating cavity 100. A first magnetic member 23 used for being magnetically connected to the sliding member 40 may further be disposed in the upper cover 21, and/or, a second magnetic member 43 used for being magnetically connected to the upper cover 21 may further be disposed in the sliding member 40. The first magnetic member 23 may be a magnet and may be embedded at a bottom of the upper cover 21. The second magnetic member 43 may be a magnet and may be suspended in the sliding member 40, and may be fixedly mounted on a lower side of the limiting member 45. The limiting member 45 may be made of a magnetic material that can be attracted by the second magnetic member 43, for example, may be made of an iron material.
