Description

Technical Field

[0001] The present invention relates to the field of atomization, and more particularly to an aerosol generating device. Background Art

[0002] A heat-not-burn atomizer is an aerosol generating device that heats the atomizing material by low-temperature heating without burning to form an inhalable aerosol. At present, a heat-not-burn atomizer usually heats the atomizing material by inserting a heater such as a heating plate into the atomizing material, and by controlling the heating temperature, the components in the atomizing material are volatilized to generate an aerosol for people to inhale. When an aerosol generating substrate is heated for a certain period of time and the amount of aerosol generated reaches the upper limit, it is necessary to pull the aerosol generating substrate out of the atomizer, or stop inhaling, or replace it with a new aerosol generating substrate to continue inhaling. The existing heat-not-burn atomizer generally removes the aerosol generating substrate from the atomizer by manual pulling. Due to the different strengths of the users, the pulling force also varies greatly. Many users often cause the aerosol generating substrate to break when pulling, or the aerosol generating substrate and the contact part of the heater to adhere to form residues on the heater, which affects the heating effect of the next use, such as producing a burnt smell.

[0010] In some embodiments, the heating element has a thickness direction, and the movement direction of the pressing member is perpendicular to the thickness direction of the heating element.

[0011] In some embodiments, the upper end of the heating element is provided with a pointed guide structure that facilitates insertion into the aerosol generating substrate.

[0012] In some embodiments, the aerosol generating device further comprises a driving mechanism connected to the at least one pressing member for driving the at least one pressing member to move.

[0013] In some embodiments, the driving mechanism includes at least one button disposed on the housing for pressing the at least one pressing member.

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0032] like Figure 1-5 As shown, the aerosol generating device in some embodiments of the present invention may be roughly in the shape of a square column and include a shell 1 and a heating element 3, a pressing member 4 and a battery 8 arranged in the shell 1. A receiving space 20 for inserting an aerosol generating substrate 9 is formed in the shell 1. The aerosol generating substrate 9 may be a cigarette, which may include an outer layer 91 and an atomizing matrix 92 arranged at the bottom of the outer layer 91. Among them, the outer layer 91 may be an outer wrapping paper, and the atomizing matrix 92 may be a solid sheet or filamentary grass leaf. The upper end of the heating element 3 may extend into the receiving space 20 and be inserted into the atomizing matrix 92 of the aerosol generating substrate 9, and the atomizing matrix 92 may be baked and heated to form an aerosol that can be inhaled by the user. It can be understood that the aerosol generating device is not limited to a square columnar shape, and it may also be in other shapes such as a cylindrical shape.

[0033] The shell 1 may be roughly in the shape of a rectangular parallelepiped, and a circular tubular extraction tube 2 may be disposed longitudinally in the shell 1. The extraction tube 2 may be assembled with the top wall of the shell 1, and the inner wall surface of the extraction tube 2 defines a receiving space 20. In other embodiments, the extraction tube 2 may also be formed by the top wall of the shell 1 extending downward as a whole.

[0034] The extraction tube 2 has a bottom wall 21, on which a socket 210 is formed for the heating element 3 to pass through, and the upper end of the heating element 3 passes through the socket 210 and extends into the receiving space 20. The heating element 3 can be in the form of a sheet or a rod (i.e., a column), and the upper end of the heating element 3 can also be provided with a pointed guide structure to facilitate insertion into the aerosol generating substrate 9. The shape of the socket 210 corresponds to the shape of the cross section of the heating element 3, and the cross-sectional dimension of the socket 210 can be slightly larger than the cross-sectional dimension of the heating element 3, so that the heating element 3 and the socket 210 are gap-matched to facilitate the insertion of the heating element 3. In this embodiment, the heating element 3 is in the form of a sheet, and the socket 210 is a rectangle with a cross-sectional dimension slightly larger than the cross-sectional dimension of the heating element 3. The aerosol generating device can also include a heating seat 30 for mounting the heating element 3, and the lower end of the heating element 3 can be inserted into the heating seat 30.

[0035] The pressing member 4 is movably fitted to the periphery of the atomizing matrix 92, and can move back and forth between a first position and a second position relative to the accommodating space 20. Among them, when the pressing member 4 is in the first position, the pressing member 4 does not contact the aerosol generating matrix 9 or contacts but does not apply pressure to the aerosol generating matrix 9, and the aerosol generating matrix 9 does not deform or slightly deforms. When the pressing member 4 is in the second position, the pressing member 4 presses the aerosol generating matrix 9, and the aerosol generating matrix 9 is squeezed and deformed, so that the friction between the outer layer 91 and the atomizing matrix 92 increases. Preferably, the movement direction of the pressing member 4 is perpendicular to the thickness direction of the heating element 3, and the atomizing matrix 92 can be separated from the heating element 3 while increasing the friction between the outer layer 91 and the atomizing matrix 92, which is more conducive to pulling out. In other embodiments, the movement direction of the pressing member 4 and the thickness direction of the heating element 3 can also be set at an acute angle, rather than parallel to the thickness direction.

[0036] Specifically, there may be two pressing members 4, and the two pressing members 4 are respectively arranged on two opposite sides of the heating element 3 along the width direction. Two openings 220 communicating with the inside and outside are formed on the side wall of the extraction tube 2, respectively corresponding to the two pressing members 4, so that when the pressing members 4 move inward, they can squeeze the aerosol generating substrate 9 through the openings 220 and thus squeeze the atomizing matrix 92. Each pressing member 4 may include a square plate-shaped main body 41 and a pressing portion 42 formed by the inner side surface (the side facing the receiving space 20) of the main body 41 protruding inward. The inner side surface of the pressing portion 42 in contact with the aerosol generating substrate 9 may be a plane or a convex curved surface or an inner concave curved surface matching the outer shape of the aerosol generating substrate 9. In the present embodiment, the inner side surface of the pressing portion 42 in contact with the aerosol generating substrate 9 is a convex arc surface.

[0037] The aerosol generating device may also include a button 5, a bracket 6 and an elastic member 7. The button 5 is arranged on the housing 1 and is used to press the pressing member 4. There are two buttons 5 and they are arranged one by one with the pressing member 4. The two buttons 5 are respectively arranged on two opposite sides of the housing 1 along the width direction, which is convenient for pressing operation. The movement direction of the button 5 is consistent with the movement direction of the pressing member 4. By pressing the button 5 inward, the pressing member 4 can be pushed to move inward to clamp the aerosol generating substrate 9. The button 5 can be manufactured separately from the pressing member 4 and then assembled together, or the button 5 can also be integrally formed with the pressing member 4. It can be understood that in other embodiments, the number of buttons 5 and pressing members 4 can also be one or more than two. In other embodiments, the movement of the pressing member 4 can also be driven by other driving mechanisms such as wedge blocks, gear racks, levers, etc. At this time, the movement direction of the pressing member 4 can also be at a certain angle to the movement direction of the driving mechanism.

[0038] The elastic member 7 is arranged in the housing 1, and is used to elastically maintain the pressing member 4 in the first position. The bracket 6 is arranged in the housing 1, and is used to fix and guide the pressing member 4 and the elastic member 7. The bracket 6 is in the shape of a square cylinder and is sleeved outside the extraction tube 2. Two opposite sides of the bracket 6 correspond to the two pressing members 4 and form two connecting ports 60 connecting the inside and the outside. The other two opposite sides of the bracket 6 are respectively provided with a guide shaft 61, and the extension direction of the two guide shafts 61 is parallel to the movement direction of the pressing member 4 and the two guide shafts 61 are respectively located on both sides of the connecting port 60 and the opening 220, and the two opposite sides of the main body 41 of the pressing member 4 can be slidably sleeved on the two guide shafts 61. The guide shaft 61 can be integrally formed with the bracket 6, or it can be separately manufactured with the bracket 6 and then assembled together. The four corners of the inner side surface of the main body 41 can also be protruded to form a limit portion 43, and the four limit portions 43 can be movably hooked in the four corners of the connecting port 60 to prevent the pressing member 4 from falling out. The bracket 6 can also be fixed to the shell 1 by a snap connection. In the present embodiment, a snap 63 is protruded from the outer wall of the bracket 6, and a slot corresponding to the snap 63 is formed on the shell 1. The snap 63 and the slot are snapped together to fix the bracket 6 to the shell 1.

[0039] The elastic member 7 may be a spring, and there may be four elastic members 7, which are respectively sleeved on both ends of the two guide shafts 61, that is, an elastic member 7 is sleeved on both ends of each guide shaft 61. One end of each elastic member 7 abuts against the main body 41 of the pressing member 4, and the other end abuts against the bracket 6. In other embodiments, the pressing member 4 may also be reset from the second position to the first position by manual reset, so that the elastic member 7 may not be provided.

[0040] like Figure 3 As shown, when the elastic member 7 is in a natural state without external force, the pressing member 4 is in the first position. At this time, after the aerosol generating substrate 9 is loaded into the accommodating space 20 from the top of the shell 1, the pressing member 4 does not contact with the outer covering 91 or contacts but does not apply pressure to the aerosol generating substrate 9. The aerosol generating substrate 9 does not deform or deforms slightly. After being powered on and heated, the heating element 3 bakes and heats the atomizing matrix 92 to generate aerosol for the user to inhale.

[0041] After the aerosol generating substrate 9 is heated, the atomizing substrate 92 shrinks, resulting in a decrease in the friction between the outer layer 91 and the atomizing substrate 92. If the aerosol generating substrate 9 is directly pulled out, the atomizing substrate 92 will adhere to the heating element 3. Figure 5As shown, in order to prevent the atomizing matrix 92 from sticking to the heating element 3 when being pulled out, the user can press the button 5 inward, so that the pressing piece 4 moves inward to clamp the aerosol generating matrix 9, and the outer covering 91 moves inward and contacts the atomizing matrix 92. The friction between the outer covering 91 and the atomizing matrix 92 becomes larger, and the aerosol generating matrix 9 can be pulled out by hand while pressing. The entire aerosol generating matrix 9 including the atomizing matrix 92 can be pulled out together.

[0042] It can be understood that the above-mentioned technical features can be used in any combination without limitation.

[0043] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
