The structure and working principle of the smoke suction device will be further elaborated below with regard to the specific example of electric heating:

Specific embodiment one

As shown in Fig. 1, Fig. 2 and Fig. 3, the present embodiment discloses a smoke suction device, including a smoke generator 10, a controller 22, an air inlet 23, an air outlet 111 and a power supply for the smoke generator 10 Power 20. The smoke generator 10 includes a cavity 101 suitable for filling the solid smoking substance 30 , and a heating area for heating the solid smoking substance 30 is provided in the cavity 101 . Wherein, the power supply 20 is provided with a battery 21 , the controller 22 is provided between the battery 21 and the cavity 101 , the air inlet 23 is provided at one end of the power supply 20 , and the air outlet 111 is provided at one end of the smoke generator 10 . When the smoke suction device is working, the airflow first enters the cavity 101 from the air inlet 23 , and then is discharged from the air outlet 111 through the cavity 101 . In this embodiment, as shown in FIG. 2, the heating area includes three sections of heating areas arranged along the axial direction of the cavity 101, each section of heating area is provided with a corresponding heating element, specifically, it includes a first heating area area 13 , a second heat generating area 14 and a third heat generating area 15 . The heating elements in the three-stage heating areas are respectively electrically connected to the controller 22, and the controller 22 controls the three-stage heating areas to sequentially heat the solid smoking material 30 in the cavity 101 section by section along the airflow direction, specifically , the controller 22 first controls the third heating region 15 to work alone, after a period of time, the controller 22 controls the third heating region 15 to not work and the second heating region 14 to work alone, and after a period of time, controls the first heating region 13 Work. In other embodiments, the heat-generating regions can also be set in two stages or other stages as required, and the heat-generating regions can also be set to work sequentially against the order of the airflow direction according to design requirements.

As shown in Figure 2 again, a counting module 221 is also arranged in the controller 22, and the counting module 221 is used to accumulate the working hours of the first heating area 13, the second heating area 14 and the third heating area 15 respectively, and will accumulate to Feedback of the numerical value to the controller 22, so that the controller 22 can accurately control the power-on or Power-off working state. For example: when the cumulative working time in the third heating area 15 reaches the preset time value, cut off the power supply of the third heating area 15, make it no longer work, start the second heating area 14 to work and accumulate the second heating The working time of the area 14, so that when the working time of the third heating area 15 reaches the preset value, an alarm prompts to replace the solid smoking substance 30 .

As shown in Fig. 2 and Fig. 3, the controller 22 is also provided with a detection unit 222, a preheating control module 223 and a temperature detection module 224 for detecting the temperature of the solid smoking substance 30, and the detection unit 222 is used for Detecting whether the cavity 101 is filled with the solid smoking substance 30 enables the controller 22 to accurately control the working state of the heating area. When the detection unit 222 detects that the cavity 101 is filled with the solid smoking substance 30 , it transmits the information that the cavity 101 is filled with the solid smoking substance 30 to the controller 22 . The temperature detection module 224 is preset with a preheating temperature t (eg: 70°C), and the preheating control module 223 is used to activate the first heating region 13 after the detection unit 222 detects that the cavity 101 is filled with solid smoking substances 30 1. The second heating area 14 and the third heating area 15 heat the solid smoking material 30 at the same time until the temperature of the solid smoking material 30 reaches the preheating temperature t. Conversely, when the detection unit 222 detects that the cavity 101 is not filled with the solid smoking substance 30, the power supply of each heating area is cut off. The pre-heating control module 223 is a module that works cyclically, that is, after the cavity 101 is filled with the solid smoking material 30, the pre-heating control module 223 works cyclically after a period of time to maintain the temperature of the solid smoking material 30 at Preheating temperature t. The purpose of this is to use the detection unit 222 to make the products produced by the technology of the present invention more intelligent; maintaining the temperature of the solid smoking substance 30 at the preheating temperature t can also make the smoke out of the present invention more rapid.

In this embodiment, in order to facilitate the filling of the solid smoking material 30 , the first heating area 13 , the second heating area 14 and the third heating area 15 are arranged coaxially in the cavity 101 . The detection unit 222 uses a mechanical switch. Specifically, the mechanical switch includes a transmission rod 16, a first electrode 17 and a second electrode 18. When the cavity 101 is filled with solid smoking material 30, the transmission rod 16 first abuts against As the first electrode 17 is loaded again with the solid smoking substance 30 , finally, as shown in FIG. 3 , the first electrode 17 and the second electrode 18 are electrically connected.

As shown in FIGS. 1 and 2 , the smoke suction device also includes a suction nozzle 11 arranged at the end of the air outlet 111 , and a filter member 12 for filtering smoke. The suction nozzle 11 is connected to the air outlet 111 . The filter member 12 is arranged between the air outlet 111 and the cavity 101, and the filter member 12 is made of mesh or microporous material. In this embodiment, the filter member 12 is made of filter cotton.

In this embodiment, the solid smoking substance 30 is solid tobacco, and in other embodiments, the solid smoking substance 30 can also be tobacco cream or Chinese herbal medicine.

The above implementation is just one of the preferred solutions. Theoretically, in other embodiments, the counting module 221 can also be configured to accumulate The number of times of work (the number of power-on times), that is, when the power-on times of the third heating area 15 reach the preset value, switch to the second heating area 14 to work; when the power-on times of the second heating area 14 reach the preset value, switch to the second The first heating area 13 works; when the number of energizations of the first heating area 13 reaches a preset value, an alarm prompts to replace the solid smoking substance 30 . The counting module 221 can also be set to be used for accumulating the number of times of smoke output from the air outlet 111. When there is an airflow passing through the air outlet 111, the air pressure switch arranged in the smoke suction device is energized. At this time, the counting module 221 counts once until counting When the number of times reaches a preset value, switch to the second heating area 14 to work, and the count is cleared; When the preset value is reached once, an alarm prompts to replace the solid smoking substance 30 .

Specific embodiment two

As shown in Figure 4, this embodiment also discloses another smoke suction device, which is different from the first embodiment: the detection unit 222 also adds an electronic switch on the basis of the mechanical switch; the controller 22 does not set As for the temperature detection module 224, only the preheating control module 223 is provided in the controller 22. The electronic switch wherein selected for use is dry reed switch 19. The preset time T is preset in the preheating control module 223, and the preheating control module 223 is used to activate the first heating region 13 and the second heating region after the detection unit 222 detects that the cavity 101 is filled with solid smoking material 30 14 and the third heating area 15 heat the solid smoking material 30 at the same time, and stop heating until the time for heating the solid smoking material 30 reaches the preset time T; after a period of time, start the first heating area 13 and the second heating area again 14 and the third heating area 15 heat the solid smoking material 30 at the same time, so that the temperature of the solid smoking material 30 can be maintained at a certain predetermined temperature.
