Detailed Description

In this application, it is to be understood that terms such as "including" or "having" are intended to indicate the presence of the disclosed features, numbers, steps, acts, components, parts, or combinations thereof, and are not intended to preclude the presence or addition of one or more other features, numbers, steps, acts, components, parts, or combinations thereof.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The application is further described with reference to examples of embodiments shown in the drawings.

As shown in figures 1-4, embodiments of the present application provide an aerosol-generating device 1 comprising: a heating chamber 101 for heating a solid smoking substance, a reservoir 102 for storing a liquid smoking substance, and a lower connecting tube 103; a first end of the lower connecting pipe 103 is communicated with the bottom of the heating cavity 101, and a second end of the lower connecting pipe 103 is communicated with the bottom of the liquid storage chamber 102; the top of the reservoir space of the reservoir 102 is open to the atmosphere.

The solid smoking material is, for example, a heated non-burning tobacco rod 2 and the liquid smoking material is, for example, tobacco tar or spices.

When the user sucks, negative pressure is generated in the internal space of the heating cavity 101, air flow flows into the heating cavity 101 from the top of the liquid storage space of the liquid storage chamber 102 through the liquid storage space and the lower connecting pipe 103, and meanwhile, liquid smoking substances in the liquid storage chamber 102 are brought into the heating cavity 101 along with the air flow, so that the liquid smoking substances and the solid smoking substances in the heating cavity 101 are heated together. Each time a user draws a puff, a portion of the liquid smoking substance will be drawn into the heating chamber 101, thus effecting a progressive filling of the heating chamber 101 with liquid smoking substance.

Of course, if the suction resistance is too large, an additional air intake passage may be added to the heating chamber 101.

Specifically, a heating element (not shown) may be disposed within the heating space 104 of the heating chamber 101. The heating space 104 may be provided with a smoking section for heating the nonflammable cigarette 2, or may be provided with other solid smoking materials such as tobacco shreds. A first air flow channel 105 is formed in the lower connection pipe 103. The shape, size and internal configuration of the first airflow channel 105 may be designed such that the airflow can smoothly carry the liquid smoking material into the heating chamber 101, and may be flexibly set by those skilled in the art based on experimental results.

Optionally, the lower connection tube 103 is U-shaped. The bottom of the heating chamber 101 is at the same height as the bottom of the reservoir 102 in fig. 2. Of course, the bottom of the heating chamber 101 may be higher or lower than the bottom of the liquid storage chamber 102, and those skilled in the art can adjust the bottom according to the experimental results. For example the top of the liquid reservoir 102 is lower than the bottom of the heating chamber 101, then it can be seen that the liquid reservoir 102 is located entirely directly below the heating chamber 101, thereby making the aerosol-generating device 1 more compact.

Optionally, the upper end opening of the reservoir 102 and/or the lower end opening thereof is pre-closed. In this way, it is ensured that no leakage of liquid smoking material occurs during transport and storage. These seals are reopened when suction is required.

Optionally, the aerosol-generating device 1 further comprises an upper connection tube 106, a first end of the upper connection tube 106 is connected to the atmosphere, and a second end of the upper connection tube 106 is connected to the upper end opening of the liquid storage chamber 102. The upper connecting tube 106 is provided to prevent leakage of liquid smoking material from the upper portion of the reservoir 102 when suction is applied.

Optionally, the upper connecting tube 106 extends vertically with its first end higher than its second end. Leakage of liquid smoking material is further avoided.

The reservoir 102 may be a large reservoir volume that stores liquid smoking material sufficient to handle multiple puffs of solid smoking material.

In other embodiments, referring to fig. 2 and 3, the liquid storage chamber 102 has a fixed member 107 and a movable member 108, the movable member 108 is divided into a plurality of sub-liquid storage chambers 109 independent of each other, the plurality of sub-liquid storage chambers 109 are distributed around a vertical axis, the movable member 108 can rotate around the axis, and during the rotation of the movable member 108 around the axis, the bottom of any sub-liquid storage chamber 109 can be uniquely communicated with the lower connecting pipe 103.

In this manner, liquid smoking material stored in one of the sub-reservoirs 109 may be consumed for each puff. At this time, the amount of liquid smoking material stored in the single sub-reservoir 109 is typically in the range of 0.1ml to 1 ml. After using up the liquid smoking substance in one sub-reservoir 109, the user only needs to rotate the moving member 108 to communicate the other sub-reservoir 109 with the lower connecting tube 103, so that the liquid smoking substance in the next sub-reservoir 109 can be consumed continuously.

Alternatively, the plurality of sub-reservoirs 109 may be the same in shape and size, the plurality of sub-reservoirs 109 may be the same distance from the axis, and the plurality of sub-reservoirs 109 may be evenly distributed along the circumference of the axis. Thus, the quantitative design of the storage space of the sub-reservoir 109 and the structural design of the movable member 108 are facilitated.

Optionally, in case the aerosol-generating device 1 further comprises an upper connection tube 106, the second end of the upper connection tube 106 is located opposite to the second end of the lower connection tube 103, and when the bottom of any one of the sub-reservoirs 109 is exclusively in communication with the lower connection tube 103, the top of that sub-reservoir 109 is exclusively in communication with the upper connection tube 106. That is, at the same time, it is possible to realize that only the upper end of one sub-reservoir 109 is communicated with the atmosphere and the lower end thereof is communicated with the heating chamber 101.

Optionally, the sub-reservoirs 109 are circular in cross-section. Thus, the sub-reservoirs 109 can be uniformly arranged.

Alternatively, stationary member 107 comprises an outer shell that is semi-enclosed by moveable member 108. For example, referring to fig. 3, the housing wraps around the outwardly facing general surface of the moveable member 108 to prevent inadvertent movement of the moveable member 108 without interfering with the user's rotation of the moveable member 108.

The embodiments in the present application are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments.

The protective scope of the present application is not limited to the above-described embodiments, and it is apparent that various modifications and variations can be made to the present application by those skilled in the art without departing from the scope and spirit of the present application. It is intended that the present application also include such modifications and variations as come within the scope of the appended claims and their equivalents.
