the heating mechanism is arranged in the second chamber and is in heat conduction connection with the filter screen; and

a thermally conductive post in thermally conductive connection with the filter screen or the heat generating mechanism, and at least a portion of the thermally conductive post is located in the first chamber.

In one embodiment, one end of the heat-conducting column is fixedly connected with the filter screen, and the other end of the heat-conducting column extends to the first chamber. So, the heat transfer that the mechanism that generates heat produced to the filter screen, the filter screen is again with heat transfer to heat conduction post, and heat conduction post is again with heat transfer to tobacco products's inside.

In one embodiment, the filter screen has a connection area, the heat-conducting column is fixedly connected to the connection area, and the heat-generating mechanism is in heat-conducting connection with the connection area. So, the heat that the mechanism that generates heat produced at first transmits the linking area to the filter screen, and the heat of the linking area of filter screen can directly transmit to the heat conduction post on to further shortened the heat by the heat conduction distance of the mechanism to the heat conduction post that generates heat, be favorable to further shortening preheating time.

In one embodiment, the heating mechanism includes a heat conducting rod and a heating wire, the heat conducting rod is installed in the second chamber, one end of the heat conducting rod facing the filter screen is in contact with the connecting area of the filter screen, and the heating wire is wound around the heat conducting rod.

In one embodiment, the filter screen is provided with a through hole, one end of the heat-conducting column is fixedly connected with the heating mechanism, and the other end of the heat-conducting column extends to the first chamber through the through hole. Therefore, heat generated by the heating mechanism is directly transferred to the heat conduction column and then transferred to the tobacco product in the first cavity through the heat conduction column so as to preheat the tobacco product. Because the heat that the mechanism that generates heat produced directly transmits to the heat conduction post, recycles the heat conduction post and preheats the tobacco, the heat conduction distance that further shortens is favorable to further shortening preheating time.

In one embodiment, the heating mechanism comprises a heat conducting rod and a heating wire, the heat conducting rod is installed in the second chamber, one end of the heat conducting rod, facing the filter screen, is in contact with the filter screen, and the heating wire is wound on the heat conducting rod;

So, the heating wire heats the heat conduction stick, and the heat conduction stick transmits the heat to heat conduction post and filter screen respectively, and the filter screen preheats tobacco products in first cavity with heat transfer to first body, recycle filter screen, first body and heat conduction post.

In one embodiment, the heat conducting post is integrally formed with the heat conducting rod. Therefore, the heat conduction efficiency between the heat conduction rod and the heat conduction column is improved, and the preheating time is further shortened.

In one embodiment, the heat conduction column is gradually reduced in radial size from one end close to the filter screen to the other end far away from the filter screen.

A heated non-burning smoking article comprising a heating assembly as described in any of the embodiments above.

When a user performs suction action, cold air enters the second chamber from the air inlet under the action of suction force generated by the suction action and flows to the first chamber.

In order to enable the user to generate smoke in a timely manner during smoking, the smoking set therefore requires preheating of the tobacco product in the first chamber prior to smoking by the user. When preheating, the heat transfer that the mechanism that generates heat produced is to filter screen and heat conduction post for filter screen and heat conduction post preheat the tobacco products in the first cavity. Because the heat conduction post can pierce the inside of tobacco products for the heat can transmit to tobacco products's inside fast, thereby is favorable to shortening preheating time, promotes the smog volume, is favorable to increasing the smog volume of three preceding mouthfuls when user's suction, promotes user's experience.

An embodiment of the present invention provides a smoking set without burning, which directly heats a tobacco product a by a technique of heating without burning to generate smoke, so as to achieve a satisfaction similar to that of a cigarette, and does not burn the cigarette, so as to avoid generation and inhalation of harmful substances during burning. The tobacco product a may be a tobacco sheet, a cigarette, a cut tobacco, or the like, and is not limited herein.

The non-combustible heating smoking set comprises a heating element 100 and a power supply element (not shown), wherein the power supply element provides electric energy for the heating element 100, the heating element 100 is used for heating air, and the heated hot air is used for baking and steaming the tobacco product A to form smoke. The power supply assembly may be implemented by using a mature technology, as long as the power supply to the heating assembly 100 can be implemented, which is not described herein.

Referring to fig. 1 and fig. 2, in the present embodiment, the heating assembly 100 includes a tube 10, a filter 20, a heating mechanism 30 and a heat-conducting pillar 40. The filter screen 20 is disposed in the tube 10 and divides an inner cavity of the tube 10 into a first chamber 111 and a second chamber 121. I.e. the first and

second chambers

111 and 121 are located on opposite sides of the screen 20. The first chamber 111 is used for containing the tobacco product a, and the strainer 20 is mainly used for filtering the scraps and the like generated by the tobacco product a placed in the first chamber 111 and preventing the scraps and the like from falling into the second chamber 121. The tube 10 is opened with an air inlet 122 communicating with the second chamber 121, and the external cold air enters the second chamber 121 through the air inlet 122 under the suction force generated by the suction action.

The heating mechanism 30 is disposed in the second chamber 121 and is thermally connected to the filter 20. The heating mechanism 30 is used for heating cold air entering the second chamber 121 through the air inlet hole 122, and the heated hot air enters the first chamber 111 through the filter screen 20 under the action of suction force, and is used for baking and steaming the tobacco product a in the first chamber 111. The heat conducting column 40 is in heat conducting connection with the filter screen 20 or the heating mechanism 30, and at least a portion of the heat conducting column 40 is located in the first chamber 111, so that the heat conducting column 40 conducts heat into the first chamber 111 and preheats the tobacco product a in the first chamber 111.

In the heating assembly 100, when a user performs a suction action, cool air enters the second chamber 121 through the air inlet hole 122 and flows toward the first chamber 111 under the suction force generated by the suction action. At this time, the heating mechanism 30 heats the air in the second chamber 121, so that the air passing through the filter net 20 and entering the first chamber 111 is hot air, and the hot air dries and steams the tobacco product a in the first chamber 111 to form smoke for the user to suck.

Furthermore, in order to enable the user to generate smoke in a timely manner during smoking, the smoking set needs to preheat the tobacco product a in the first chamber 111 before the user can smoke. During preheating, heat generated by the heating mechanism 30 is transferred to the strainer 20 and the heat conducting pillar 40, so that the strainer 20 and the heat conducting pillar 40 preheat the tobacco product a in the first chamber 111. Because heat conduction post 40 can pierce tobacco products A's inside for the heat can be transmitted to tobacco products A inside fast, thereby is favorable to shortening preheating time, promotes the smog volume, is favorable to increasing the smog volume of three preceding mouthfuls when user's suction, promotes user's experience.

The heat-conducting pillar 40 may be a regular pillar or a special-shaped pillar, such as a truncated cone, a cylinder, a prism, or a pyramid, and the like, without limitation. Preferably, the heat-conducting studs 40 have a radial dimension that decreases progressively from one end close to the sieve 20 to the other end remote from the sieve 20 (for example, truncated cone, cone or pyramid, etc.), so as to make it easier for the heat-conducting studs 40 to penetrate into the tobacco product a, thus achieving a better fixing and preheating effect.

Alternatively, the material of the heat conducting column 40 may be a metal material such as an aluminum alloy and stainless steel, or an inorganic high temperature resistant material such as ceramic and glass, which is not limited herein.

It should be further noted that, the heat of the heating mechanism 30 is transferred to the tobacco product a in the first chamber 111 by using the heat conduction function of the filter screen 20 and the heat conduction column 40, so as to preheat the tobacco product a, and thus, a heating element for preheating does not need to be separately arranged in the first chamber 111, thereby simplifying the structure of the heating assembly 100 and reducing the production cost.
