Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1, 2 and 3, an aerosol-generating device 10 according to an embodiment of the present invention includes a housing 11, a heater 12 and a conduction mechanism 13. The heater 12 and the conducting mechanism 13 are both accommodated in the housing 11, and the housing 11 accommodates and protects the heater 12 and the conducting mechanism 13.

In some embodiments, the heater 12 includes a heating tube 100 and a heat transfer core 200, the heat transfer core 200 is at least partially received in a lumen of the heating tube 100, and a remaining space of the lumen of the heating tube 100 not filled by the heat transfer core 200 includes a heating cavity 110, and the heating cavity 110 is actually an open cavity which can be connected to the outside. The aerosol substrate 20 may be a solid columnar structure, for example, the aerosol substrate 20 may be a cylindrical structure, the aerosol substrate 20 may be inserted into the heating cavity 110 from the outside, and the heating cavity 110 may limit and contain the aerosol substrate 20. A portion of the aerosol substrate 20 may be contained in the heating chamber 110, the portion located in the heating chamber 110 containing an active ingredient capable of generating an aerosol. Another portion of the aerosol substrate 20 may be exposed outside of the heating chamber 110, which portion may not contain an active ingredient capable of generating an aerosol, and which portion may be contacted by a user for inhalation. In other embodiments, the nebulized matrix 20 can also be a semi-solid paste.

The heating pipe 100 includes a pipe body 120 and a heating resistor, the pipe body 120 encloses the heating chamber 110, the heating resistor is attached to an inner wall surface of the heating chamber 110, and the heating resistor is made of a metal material. For example, the heating resistor may be directly attached to an inner wall surface of the heating chamber 110 such that the heating resistor protrudes from the inner wall surface by a certain height in an axial direction perpendicular to the tube body 120. In another example, a sunken groove may be formed on an inner wall surface of the heating cavity 110, so that the heating resistor is matched with the sunken groove, in other words, the heating resistor is embedded in the heating tube 100, and a surface of the heating resistor may be flush with the inner wall surface. When the heating resistor is energized, the heating resistor converts the electric energy into heat energy, the heat energy of the heating resistor is conducted to the inner wall surface of the heating cavity 110, and under the condition that the atomized substrate 20 is accommodated in the heating cavity, the atomized substrate 20 is in contact with the inner wall surface and the heating resistor, so that the heat energy on the inner wall surface and the heating resistor is conducted to the atomized substrate 20, and the atomized substrate 20 absorbs the heat energy and reaches the atomization temperature, thereby atomizing to form aerosol which can be sucked by a user.

In some embodiments, the heat transfer core 200 may be made of a material with a high thermal conductivity, such that the heat transfer core 200 has good thermal conductivity. The heat transfer core 200 is provided with a heat transfer hole 210, and the heat transfer hole 210 is communicated with the heating cavity 110. The number of the heat transfer holes 210 may be plural, and the plural heat transfer holes 210 are uniformly distributed on the heat transfer core 200. The apertures of each heat transfer aperture 210 may be equal. For example, the heat transfer hole 210 may be a cylindrical hole, i.e., the diameter of the heat transfer hole 210 is constant along the axial direction of the heat transfer hole 210. As another example, the heat transfer hole 210 may be a tapered hole, i.e., the diameter of the heat transfer hole 210 may gradually decrease along the central axis of the heat transfer hole 210 in a direction from the heat transfer hole 210 to the heating chamber 110. When the heat pipe 100 generates heat, in view of the good heat conducting function of the heat transfer core 200, a part of the heat pipe 100 is conducted to the heat transfer core 200, so that the heat transfer core 200 absorbs the heat and increases the temperature.

When a user draws, the atomizing substrate 20 will atomize to form aerosol, and ambient air will enter the heating chamber 110 from the heat transfer holes 210, and the air will be absorbed by the user together with the aerosol. During the atomization of the atomizing substrate 20, the atomizing substrate 20 directly absorbs the heat of the heating tube 100 to atomize. On the other hand, when the normal temperature gas enters the heat transfer holes 210, the normal temperature gas exchanges heat with the heat transfer core 200 in the heat transfer holes 210, that is, the normal temperature gas absorbs heat of the heat transfer core 200 in the heat transfer holes 210 and is converted into high temperature gas, the high temperature gas further enters the heating cavity 110, and the atomized matrix 20 in the heating cavity 110 absorbs heat of the high temperature gas and is atomized. The heat generated by the heating tube 100 and the heat of the hot gas flowing from the heat transfer holes 210 will atomize the atomizing substrate 20.

In view of the fact that the aerosol substrate 20 can be heated by the hot gas, the hot gas will penetrate into various regions of the inside and surface of the aerosol substrate 20, i.e. the hot gas will be evenly distributed within the aerosol substrate 20, so that each part of the aerosol substrate 20 absorbs the same amount of heat and is raised to the same temperature, i.e. the hot gas heats the aerosol substrate 20 evenly, which also improves the smoking experience of the aerosol. In view of the number of the heat transfer holes 210 being a plurality, and the aperture of the heat transfer holes 210 being relatively small, the residence time of the normal temperature gas in the heat transfer core 200 can be reasonably prolonged, so that the normal temperature gas has sufficient time to exchange heat with the heat transfer core 200, and the normal temperature gas is ensured to absorb enough heat to be converted into high temperature gas with reasonable high temperature, so that the temperature of the high temperature gas formed by converting the normal temperature gas reaches the set requirement.

In some embodiments, the conduction mechanism 13 includes a middle conduction assembly 300 and an end conduction assembly 400, one end of the middle conduction assembly 300 is connected to the heating pipe 100, and the other end of the middle conduction assembly 300 is connected to the end conduction assembly 400, that is, the middle conduction assembly 300 is connected between the heating pipe 100 and the end conduction assembly 400.

In some embodiments, the middle conduction assembly 300 includes a middle catheter 320 and a stopper 330, the middle catheter 320 is a tubular structure, and the lumen surrounded by the middle catheter 320 is referred to as a middle lumen 321. The plug 330 includes a blocking portion 331, a protruding portion 332 and a connecting portion 333, the blocking portion 331 has two surfaces in the thickness direction, the protruding portion 332 is protrudingly connected to one of the surfaces, that is, one end of the protruding portion 332 is fixedly connected to the surface, and the other end of the protruding portion 332 protrudes a certain height relative to the surface. The connecting part 333 is protrudingly connected to the other surface, that is, one end of the connecting part 333 is fixedly connected to the surface, and the other end of the connecting part 333 is protrudingly connected to the surface by a certain height. So that both the projecting portion 332 and the connecting portion 333 occupy opposite sides in the thickness direction of the blocking portion 331.

During assembly, the blocking portion 331 is connected to the mid-section catheter 320 and blocks the end of the mid-section lumen 321, the protrusion portion 332 is located inside the mid-section lumen 321, the connecting portion 333 is located outside the mid-section lumen 321, and the tail section conducting assembly 400 is fixedly connected to the connecting portion 333, for example, the tail section conducting assembly 400 can be inserted into the connecting portion 333.

Specifically, the protrusion 332 includes a side cylinder 3322 and a top cover 3323, the side cylinder 3322 may have a cylindrical structure, and the side cylinder 3322 may enclose a cylindrical inner cavity 3322a, and the inner cavity 3322a is communicated with the air inlet passage 410. One end of the side cylinder 3322 is fixed to the blocking portion 331, and the other end of the side cylinder 3322 protrudes to a certain height from the blocking portion 331. The top head 3323 is connected to the other end of the side cylinder 3322 such that the top head 3323 closes off the end of the interior cavity 3322 a. The side tube 3322 has a through hole 3322b formed therein, and the through hole 3322b penetrates the entire side tube 3322 in the thickness direction of the side tube 3322 such that the through hole 3322b communicates the inner cavity 3322a with the middle lumen 321. The inner cavity 3322a and the through hole 3322b may jointly form a flow guide hole 3321, i.e., the flow guide hole 3321 includes the inner cavity 3322a and the through hole 3322b. The distance from the through hole 3322b to the blocking portion 331 is greater than the distance from the through hole 3322b to the top cover 3323 in the axial direction of the protruding portion 332, i.e., the through hole 3322b is disposed relatively closer to the top cover 3323, thereby allowing the through hole 3322b to have a certain height with respect to the blocking portion 331. The portion of the middle lumen 321 between the middle plug 330 and the middle catheter 320 forms the reservoir 311. In other embodiments, the through hole 3322b may be directly formed on the top 3323.

The liquid generated by the atomizing substrate 20 during the atomizing process can be stored in the reservoir 311, and the reservoir 311 can continue to store the liquid as long as the liquid level in the reservoir 311 does not reach the through hole 3322b due to the height of the through hole 3322b relative to the blocking portion 331. Therefore, the more liquid is stored in the reservoir 311 as the through-hole 3322b is closer to the top cover 3323.

In some embodiments, the end piece conduction assembly 400 includes an end piece conduit 420 and a plug 430, and one end of the end piece conduit 420 is connected to the connection portion 333 of the plug 330, for example, one end of the end piece conduit 420 is directly inserted into the connection portion 333. The lumen that tail section pipe 420 encloses is marked as tail section lumen 421, and chock plug 430 can form the detachable connection relation with casing 11, and chock plug 430 is corresponding with the other end that tail section pipe 420 kept away from connecting portion 333 for chock plug 430 can shutoff tail section lumen 421 keeps away from the opening of connecting portion 333 one end. The choke plug 430 is provided with an air inlet 431, the air inlet 431 is directly communicated with the outside and the tail section tube chamber 421, the air inlet 431 and the tail section tube chamber 421 jointly form an air inlet channel 410, that is, the air inlet channel 410 comprises the air inlet 431 and the tail section tube chamber 421.

The number of the air inlet holes 431 can be multiple, the caliber of the air inlet holes 431 is smaller than that of the tail section pipe cavity 421, and the air inlet holes 431 are evenly distributed on the plug head 430. When the user sucks, the external air enters the heating cavity 110 through the air inlet hole 431, the tail section pipe cavity 421, the flow guide hole 3321, the middle section pipe cavity 321 and the heat transfer hole 210 in sequence. When the number and diameter of the air inlet holes 431 are set reasonably, the amount of air taken in the air inlet channel 410 per unit time can be changed, thereby changing the suction resistance of the whole aerosol-generating device 10.

During use of the aerosol-generating device 10, when the liquid in the reservoir 311 is stored to a certain amount, the aerosol-generating device 10 may be inverted so that the liquid in the reservoir 311 flows into the heat transfer wick 200 through the middle section lumen 321 under the action of gravity. Of course, before the liquid flows into the heat transfer core 200, the heating pipe 100 must be heated, and then the heat transfer core 200 must have a certain temperature. When the liquid flows into the heat transfer core 200 with a certain temperature, the liquid absorbs the heat of the heat transfer core 200 and is atomized to form a liquid mist, and the liquid mist is discharged out of the aerosol generating device 10 from the air inlet hole 431 or the heating cavity 110, so that the liquid is automatically acted. Therefore, the aerosol generating device 10 does not need an external cleaning tool to remove liquid, the aerosol generating device 10 has the function of cleaning the liquid, the convenience of cleaning the aerosol generating device 10 is improved, the aerosol generating device 10 is prevented from being polluted by the liquid, and the liquid is prevented from being heated repeatedly in the suction process to generate peculiar smell which affects the suction taste.

In the case of excessive liquid in the liquid storage cavity 311, the liquid in the liquid storage cavity 311 will flow into the tail section cavity 421 through the through hole 3322b and the inner cavity 3322a of the protrusion 332, and the liquid entering the tail section cavity 421 will be absorbed in the liquid absorbing member 500 due to the liquid absorbing member 500, so as to effectively prevent the liquid from flowing out of the air inlet hole 431 to the outside of the aerosol generating device 10, and finally avoid the liquid leakage phenomenon generated by the aerosol generating device 10. Further, the orthographic projection of the liquid absorbing member 500 on the plug 430 covers all the air intake holes 431, so that the liquid entering the tail section cavity 421 can be more effectively prevented from further flowing into the air intake holes 431 to form leakage.
