1 to FIG. 8, an embodiment of the present application provides an aerosol-generating device 100 for heating an aerosol-generating product 200 to generate an aerosol for users to inhale. An embodiment of the present application provides an aerosol generating device 100, which includes a housing 110, a heater assembly 120, and a cylindrical body 140. The housing 110 is used to receive an aerosol-generating product 200, and a heating part of the heater assembly 120 is heated during use. The device 121 extends into the accommodating cavity 111 of the casing 110, and the aerosol-generating article 200 is inserted into the accommodating cavity 111 of the casing 110, and can be heated to generate an aerosol. As the smoke material is prepared using natural tobacco components and / or other smoke materials, a small amount of oily liquid substances including tar will overflow during the heating process, and the solid residue of the smoke material will also A small amount of leakage, these liquids and solid substances will remain on the cigarette holder accommodating cavity 111 and heater 121 of the smoking set. If they leak out, they will enter the internal space, generating odor substances that affect the use and cannot be cleaned, especially liquids. Material flowing into the circuit board or the area where the battery is located can cause serious damage to the equipment. In this application, a cylindrical body 140 is used to surround and fix the heater assembly 120 to form a space 160 for preventing material leakage. For example, the cylindrical body 140 defines an internal hollow, the heater assembly 120 is fixed to the internal hollow, and the base 122 and The inner wall of the cylindrical body 140 surrounds the substance leakage prevention space 160, so that whether it is a liquid substance generated by heating or a solid substance such as shredded tobacco, it is confined in the space 160 without contaminating other places. More damage to electronic components. In addition, the cylindrical body 140 may further include a function of connecting the pushing mechanism 130. The pushing mechanism 130 directly acts on the cylindrical body 140 and is movably coupled to the housing 110, thereby driving the heater assembly 120 from the receiving cavity. 111 exits, and the aerosol-generating product 200 is still placed in the receiving cavity 111, so that the heater 121 is separated from the aerosol-generating product 200, and the adhesion between the heater 121 and the heated aerosol-generating substance is avoided. Convenient removal of the aerosol-generating article 200. During the withdrawal of the heater assembly 120 from the receiving cavity 111, the aerosol-generating article 200 may be substantially stationary relative to the receiving cavity 111, or may move in a direction opposite to the moving direction of the heater assembly 120.

In one embodiment, the shape of the base 122 is adapted to the hollow inside of the cylindrical body 140. The upper surface of the base 122 is a complete surface without openings. The inner wall of the cylindrical body 140 is closely attached, so that the upper surface of the base 122 and the inner wall of the cylindrical body 140 define a space 160 for preventing material leakage. Since the base 122 and the cylindrical body 140 have a close relationship, The residue does not leak from its contact position, so as long as the inner walls of the base 122 and the cylindrical body 140 are not opened, the substance does not leak.

In the aerosol generating device 100 provided in the embodiment of the present application, the casing 110 is provided with a receiving cavity 111 for receiving an aerosol-generating product 200. In an embodiment, the casing 110 has a receiving cavity 111 The communicating opening 112 is used for inserting the aerosol-generating product 200 into the receiving cavity 111 through the opening 112, and the opening 112 may also be an insertion opening for a cigarette or a receiving cavity. The wall of the housing 110 defining the receiving cavity 111 may include a side wall 113 and a bottom wall 114, which are connected to each other to form a cup-shaped structure for defining the receiving cavity 111. In an embodiment, the shape of the receiving cavity 111 is adapted to the shape of the aerosol-generating product 200. The aerosol-generating product 200 is not easily carried out by the mouth or inserted into the receiving cavity 111 when inserted into the receiving cavity 111. Squeezing the aerosol-generating article 200 causes excessive deformation to increase the drag. The withdrawal of the heater assembly 120 from the accommodating cavity 111 may be that the heater assembly 120 located in the housing 110 moves in a direction away from the opening 112.

In one embodiment, the tube wall of the cylindrical body 140 extends in the direction of the opening 112 and surrounds the outer periphery of the heater 121, which can both protect the heater 121 and prevent the substance from seeping through. The leaked space 160 extends in the direction of the opening 112, and all the residue can be collected in the space 160, which is convenient for centralized cleaning.

Under the traction of the cylindrical body 140, the pushing mechanism 130 pushes the heater 121 to slide between the heating position and the separating position. The heating position is a position where the heater 121 extends into the accommodating cavity 111, and the separation position is a position where the heater 121 exits away from the accommodating cavity 111. For example, the pushing mechanism 130 pushes the heater assembly 120 to slide between a heating position and a separating position under an external force, and the heating position is a position where the heater 121 is fully inserted into the aerosol-generating product 200, The heater 121 extends into the deepest position of the accommodating cavity 111. At this time, as long as the aerosol-generating product 200 is received in the accommodating cavity 111, it can be heated to generate aerosol; the separation position is the heater 121 The position that has completely exited the accommodating cavity 111 is the farthest position where the heater 121 exits away from the accommodating cavity 111, and the heater 121 is no longer in contact with the aerosol-generating product 200 in the accommodating cavity 111.

When the heater assembly 120 is located at this position, it is waiting to insert the aerosol-generating product 200 into the receiving cavity 111, or an aerosol has been generated. The product 200 is inserted into the receiving cavity 111 to be heated or is being heated. This position may also be referred to as a working position. The separation position is a position where the heater 121 and the aerosol-generating product 200 are completely separated. When the heater assembly 120 is located at this position, it indicates that the heater 121 and the aerosol-generating product 200 have been completely separated, and the aerosol-generating product can be directly removed. 200. After the heated aerosol-generating product 200 is removed, the heater assembly 120 may be pushed back to a position extending into the receiving cavity 111 and waiting for the next work.

When the auxiliary aerosol-generating product 200 is inserted into the accommodating cavity 111, the aerosol-generating product 200 and the base 151 are pushed to the bottom of the accommodating cavity 111 by an external force, so that the base 151 and the movable hanging buckle 152 are buckled. The "back" of the base 151 cannot occur, that is, the base 151 cannot move in the direction of the opening 112 until it is triggered by the pushing mechanism 130 to separate the base 151 from the movable hanging buckle 152.

In an embodiment, a first magnet 1521 is provided on a side of the stopper, such as the movable hanging buckle 152 toward the pushing mechanism 130, and the traction member 153 includes a first magnet 1521 provided on the pushing mechanism 130. The repulsive second magnet 1531 is provided on the pushing mechanism 130 and a third magnet 1532 attracted to the first magnet 1521. For example, the pushing mechanism 130 includes a push button 131 movably coupled to the housing 110. The push button 131 is placed outside the housing 110 and extends along the length direction of the housing 110. The third magnet 1532 attracts the first magnet 1521 keeps the first magnet 1521 away from the receiving cavity 111, so that the movable hanging buckle 152 is separated from the bottom bracket 151; the second magnet 1531 repels the first magnet 1521 so that the first magnet 1521 is close to the receiving cavity 111, so that The movable hanging buckle 152 is fastened with the base 151. Due to the sliding of the pushing mechanism 130 between different positions, the first magnet 1521 and the second magnet 1531 and the third magnet 1532 generate magnetic forces at different times, for example, when the pushing mechanism 130 pushes the heater assembly 120 to Withdrawing from a position away from the receiving cavity 111, the third magnet 1532 is attracted to the first magnet 1521, and the movable hanging buckle 152 is separated from the base 151; when the pushing mechanism 130 pushes the The heater assembly 120 extends to a position extending into the accommodating cavity 111, and the second magnet 155 and the first magnet 11521 are repelled, and the buckle 152 is fastened to the bottom bracket 151.

Referring to FIG. 12, in another embodiment, a side of the limiting member 152 facing the pushing mechanism 130 is provided with a first magnet 1521, and the traction member 153 includes a first magnet disposed on the pushing mechanism 130 and the first magnet. 1521 corresponds to the second magnet 155 and the switch 157. The pushing mechanism 130 may be provided with only one magnet, that is, the second magnet 1531. At least one of the first magnet 1521 and the second magnet 1531 on the movable hanging buckle 152 is an electromagnet, and the polarity of the electromagnet is It can be controlled by the switch 158. When the switch 158 is in the first state, for example, when the switch 158 is in the ON state, the polarity of the electromagnet causes the first magnet 1521 and the second magnet 1531 to attract each other, so that the first magnet 1521 is far away from the receiving cavity 111, so that the movable hanging buckle 152 is separated from the base 151. When the switch 158 is in the second state, for example, when it is in the OFF state, the polarity of the electromagnet causes the first magnet 1521 and the second magnet 1531 to repel each other, so that the first magnet 1521 is close to the receiving cavity 111, so that the movable hanging buckle 152 is engaged with the base 151. In this embodiment, the pushing mechanism 130 may be replaced with a fixed substrate, that is, the proximity and distance between different polar magnets are not caused by the displacement of the pushing mechanism 130, but the polarity of the electromagnet is controlled by a switch to make the first The polarity of at least one of the magnet 1521 and the second magnet 1531 changes, so that the movable hanging buckle 152 and the bottom bracket 151 are fastened and separated.

In an embodiment, the wall of the housing 110 defining the receiving cavity 111 includes a side wall 113 and a bottom wall 114 connected to each other to form a cup structure. A hole is formed in the bottom wall 114 to allow the heater 121 The aerosol-generating article 200 is inserted into the receiving cavity 111. The aerosol-generating product 200 further includes a filter 210, which is disposed at the gas outflow end of the aerosol-generating product 200. The gas inflow end is opposite to the gas inflow end, and the gas inflow end also becomes the air intake end.

Therefore, holes are formed in the bottom wall 114 and air can flow into the aerosol-generating product 200 at the same time. As the user smokes, the heater 121 heats the aerosol-generating substance to form an aerosol containing the aerosol. The aerosol is then carried into the user's mouth in a flow of air. Since the air passes through the aerosol-generating substance and flows adjacent to the aerosol-generating substance, the air flows through openings in the bottom wall 114. The size and shape of the holes can be used to manage the air flow and therefore the characteristics of the aerosol.

In an embodiment, the movable hanging buckle 152 can move in a direction perpendicular to the length direction of the receiving cavity 111, and the longitudinal direction of the receiving cavity 111 is also an extension direction of the heater 121.
