One end of the heating cartridge 120 is open, the other end of the heating cartridge 120 is provided with an air inlet 122, i.e., the substance to be heated can be received in the heating cartridge 120. The open end of the heating cartridge 120 can communicate with the electronic cigarette mouthpiece.
Specifically, the heating cartridge 120 is a ceramic heating body, such as an alumina ceramic heater, a zirconia ceramic heater, and so on. It should be noted that the heating cartridge 120 is not limited to be the ceramic heating body, and the heating cartridge 120 may be a metal cylinder or the like.
The filter screen 130 is fixedly received in the heating cartridge 120 and shields the air inlet 122 to prevent the substance to be heated in the heating cartridge 120 from leaking from the air inlet 122.
Furthermore, the first heating assembly 100 further includes a supporting member (not shown). The supporting member is fixedly received in the heating cartridge 120, and the supporting member is used to carry the substance to be heated so as to carry the tobacco tar. Specifically, the supporting member can be a wire cake, ceramic honeycomb material and the like.
It should be noted that the supporting member may be omitted. In this case, the heating cartridge 120 may only be used to receive the tobacco leaves.
The second heating assembly 200 has an airflow passage 210 being in communication with the outside. The airflow passage 210 is in communication with the receiving chamber 110 to allow outside air to enter the receiving chamber 110 through the airflow passage 210. The second heating assembly 200 can heat the air entering the airflow passage 210, i.e., the airflow passage 210 is in communication with the air inlet 122.

The tubular member 220 is a metal tube. Since diameter of the tubular member 220 is small, the machining precision of the tubular member 220 made of metal is high, the stable connection of the smoking device is easy to be achieved. Furthermore, the tubular member 220 is an aluminum tube being light in texture, which is beneficial for reducing the weight of the smoking device.
Referring to
Specifically, the connecting member 410 is made of metal. Furthermore, the connecting member 410 is made of aluminum. The tubular body 412 of the connecting member 410 is in interference fit with the tubular member 220.
It should be noted that the heating cartridge 120 is not limited to the above structure. For example, the heating cartridge 120 has no bottom wall 124, and the heating cartridge 120 is a cartridge opening at both ends. In this case, one opening of the heating cartridge 120 is connected to the electronic cigarette mouthpiece, and the other opening is the air inlet 122. The manner of connecting the heating cartridge 120 and the tubular member 220 is not limited to the above. For example, the heating cartridge 120 and the tubular member 220 may be directly fixed together.
The heating member 230 is fixedly received in the tubular member 220 and can heat the air entering the tubular member 220. Specifically in the illustrated embodiment, the heating member 230 is a heating wire.
The electric control assembly 300 is an electric control part of the entire smoking device. The electric control assembly 300 is electrically connected to both the first heating assembly 100 and the second heating assembly 200, such that the electric control assembly 300 can separately supply power to the first heating assembly 100 and the second heating assembly 200 to enable the first heating assembly 100 and the second heating assembly 200 to have heating function. The electric control assembly 300 is used to control heating operations of the first heating assembly 100 and the second heating assembly 200, such that when the smoking device is working, at least one of the first heating assembly 100 and the second heating assembly 200 performs the heating operation. Specifically, both the heating cartridge 120 and the heating member 230 are electrically connected to the electric control assembly 300, such that the electric control assembly 300 can supply power to the heating cartridge 120 and the heating member 230. The electric control assembly 300 can control heating operations of the heating cartridge 120 and the heating member 230, such that when the smoking device is working, at least one of the heating cartridge 120 and the heating member 230 performs the heating operation. In order to enable at least one of the heating cartridge 120 and the heating member 230 to perform the heating operation, the heating cartridge 120 and the heating member may be disposed in parallel.
Specifically, the electric control assembly 300 is used to control the heating operations of the first heating assembly 100 and the second heating assembly 200, such that the smoking device is in a first working mode, a second working mode, a third working mode, or a fourth working mode;
In the first operation mode, the electric control assembly 300 controls the first heating assembly 100 to separately perform a heating operation, and a heating temperature of the first heating assembly 100 can be adjusted. The electric control assembly 300 supplies power to the heating cartridge 120 of the first heating assembly, but doesn't supply power to the heating member 230 of the second heating assembly. The substance to be heated is only heated by the heating cartridge 120, and the user can adjust the heating temperature of the heating cartridge 120 according to the requirements, which is a conduction heating mode and can meet the users' requirement for rapid smoke removal.
In the second operation mode, the electric control assembly 300 controls the second heating assembly 200 to separately perform a heating operation, and a heating temperature of the second heating assembly 200 can be adjusted. The electric control assembly 300 supplies power to heating member 230, but doesn't supply power to the heating cartridge 120. The heating member 230 heats the airflow entering the tubular member 220. The heated air enters the heating cartridge 120, and heats the substance to be heated in the heating cartridge 120. The users can adjust the heating temperature of the heating member 230 according to the requirements, which is an airflow heating mode and can meet the users' requirement for slowly smoking.
In the third operation mode, the electric control assembly 300 controls the first heating assembly 100 and the second heating assembly 200 to simultaneously perform the heating operations, and the heating temperatures of the first heating assembly 100 and the second heating assembly 200 can be simultaneously adjusted according to a preset adjustment amplitude. The electric control assembly 300 supplies power to both heating member 230 and the heating cartridge 120. The heating air heated by the heating member 230 and the heating cartridge 120 simultaneously supplies heat to the substance to be heated in the heating cartridge 120. This is a hybrid heating mode, which can meet the requirements of the users for great smoke. In this mode, the heating temperatures of the heating member 230 and the heating cartridge 120 are simultaneously adjusted according to the preset adjustment amplitude.
Specifically, in the third operation mode, when the electric control assembly 300 controls the heating temperature of the first heating assembly 100 to rise, the electric control assembly 300 controls the heating temperature of the second heating assembly 200 to drop at the same time. It should be noted that the second heating assembly 200 and the first heating assembly 100 are not limited to the above mode in the third operation mode. The electric control assembly 300 may control the heating temperature of the first heating assembly 100 to rise, and controls the heating temperature of the second heating assembly 200 to rise at the same time.
The preset adjustment amplitude may be, for example, a plurality of preset adjustment gradients. At each gradient, the heating cartridge 120 and the heating member 230 have corresponding heating temperatures. For example, as shown in Table 1, it is assumed that the heating temperature of the heating cartridge 120 is from 140° to 220°, and the heating temperature of the heating member 230 is from 220° C. to 256° C. The heating temperature controlled by the electric control assembly 300 is divided into 100 adjusting gradients, and 1% is an adjusting gradient. Each gradient is configured to correspond to temperatures of the specific heating cartridge 120 and the specific heating member 230. For example, when the gradient is 10%, the heating temperature of the corresponding heating cartridge 120 is 140° C., and the heating temperature of the corresponding heating member 230 is 256° C.
In the fourth operation mode, the electric control assembly 300 controls the first heating assembly 100 and the second heating assembly 200 to simultaneously perform the heating operations, and the heating temperatures of the first heating assembly 100 and the second heating assembly 200 can be separately adjusted. This is the hybrid heating mode. The electric control assembly 300 supplies power to both heating member 230 and the heating cartridge 120. The heating air heated by the heating member 230 and the heating cartridge 120 simultaneously supplies heat to the substance to be heated in the heating cartridge 120. However, the difference between this operation mode and the third operation mode is that the heating temperature of the heating member 230 and the heating cartridge 120 can be separately adjusted. For example, both the heating member 230 and the heating cartridge 120 are in a non-polar adjustment mode, and the user can separately adjust the heating temperature of heating cartridge 120 and the heating temperature of the heating member 230 according to the requirements. In this mode, any adjustment within the heating temperature ranges of the heating cartridge 120 and the heating member 230 can be achieved.
Specifically, the electric control assembly 300 includes a central processing module (not shown) and an integrated circuit module (not shown) electrically connected to the central processing module. The central processing module is used to control the power supply and information processing of the entire smoking device. The central processing module may be, for example, a Single-chip microcomputer of STMicroelectronics. The integrated circuit module is electrically connected to the heating cartridge 120 of the first heating assembly 100 and the heating member 230 of the second heating assembly 200. The integrated circuit module is used to realize the electrical connection between the components and the central processing module. The integrated circuit module may be, for example, a MC95FG308H power control module integrated circuit manufactured by Korea's Hyundai.
Furthermore, the smoking device further includes a first temperature sensor 500 and a second temperature sensor 600. The first temperature sensor 500 and the second temperature sensor 600 are both electrically connected to the electric control assembly 300. The first temperature sensor 500 can detect a temperature of the heating cartridge 120 of the first heating assembly 100 and convert the temperature of the heating cartridge 120 of the first heating assembly 100 into a signal, and transmit the signal to the electric control assembly 300. The second temperature sensor 600 can detect a temperature of the tubular member 220 of the second heating assembly 200 and convert the temperature of the tubular member 220 of the second heating assembly 200 into a signal, and transmit the signal to the electric control assembly 300.

The other part of the Teflon sleeves are fixedly sleeved on the second temperature sensor 600 and the tubular member 220, so as to fix the second temperature sensor 600 on the tubular member 220. The Teflon sleeve 700 is resistant to high temperatures, and the usage of the Teflon sleeve 700 makes it easy to fix the first temperature sensor 500 onto the heating cartridge 120 and fix the second temperature sensor 600 onto the tubular member 220.

In addition, when the smoking device is working, the first heating assembly 100 and the second heating assembly 200 can separately perform the heating operations, what's more, the first heating assembly 100 and the second heating assembly 200 can also simultaneously perform the heating operations. Therefore, the smoking device can be customized to achieve conduction heating mode, the airflow heating mode, or hybrid heating mode of the conduction heating and the airflow heating according to user requirements, thereby meeting the various requirements of the user for the amount of smoke.
(2) At the same time, since the smoking device can achieve that the first heating assembly 100 and the second heating assembly 200 simultaneously perform the heating operations, i.e., achieving the hybrid heating mode of the conduction heating and the airflow heating, such that the heat supply can be guaranteed by implementing the hybrid heating mode in the cold and low temperature environment, and the heating efficiency can be improved. The air inlet 122 is provided in the middle portion of the bottom wall 124, the air heated by the tubular member 220 can directly contact with a middle portion of the substance to be heated in the receiving chamber 110. Therefore, a central position of the substance to be heated (especially the tobacco leaves) can be heated, such that the substance to be heated can be more fully heated and the utilization of the substance to be heated can be increased.
(3) The aforementioned smoking device can achieve the aforementioned four heating modes, so that the users can separately control the first heating assembly 100 to work, and adjust the temperature as required. The users can separately control the second heating assembly 200 to work, and adjust the temperature as required. The users can control the first heating assembly 100 and the second heating assembly 200 to work simultaneously, and adjust the heating temperatures of the first heating assembly 100 and the second heating assembly 200 according to the preset adjustment amplitude. The users can control the first heating assembly 100 and the second heating assembly 200 to simultaneously perform the heating operation, and separately adjust the heating temperatures of the first heating assembly 100 and the second heating assembly 200 according to the requirements, so as to enable the users to adjust the heating mode of the smoking device according to personal preferences, and to better meet the user's requirements.
(4) By setting the first temperature sensor 500 and the second temperature sensor 600 for detecting the temperatures of the first heating assembly 100 and the second heating assembly 200, respectively, the heating temperatures of the first heating assembly 100 and the second heating assembly 200 can be better controlled.
(5) By setting the connecting assembly 400 between the heating cartridge 120 and the tubular member 220, the heating cartridge 120, the connecting assembly 400, and the tubular member 220 are connected by the fixing assembly 800, so that not only the heating cartridge 120 of the ceramic heating body can be reliably connected to the tubular member 220, but also the sealed connection between the heating cartridge 120 and the tubular member 220 can be achieved. Therefore, the structure is more compact and the installation is convenient. In addition, the sealing sleeve 810 in the fixing assembly 800 is made of silicone, which can not only have the effect of insulating heat transfer between the first fixing member 820 and the heating cartridge 120, but also the sealed connection between the first fixing member 820 and the heating cylinder 120 can be achieved.
It should be noted that the second heating assembly 200 is not limited to be the aforementioned structure, for example, the tubular member 220 of the second heating assembly 200 may be the ceramic heating body. In this case, the heating member 230 may be omitted, and the tubular member 220 may be directly and electrically connected to the electric control assembly 300.
