Patent Abstract:
A tobacco baking device, comprising a mouthpiece component, a baking component, and a filter component, where the filter component is located below a baking component; the mouthpiece component is located above the baking component; the baking component is detachably connected to the filter component; where there is sealed connection on the butted terminal portions of the mouthpiece component, the filtration component and the baking component; an air flow channel is provided between the mouthpiece component, the filter component, and the baking component. Vapor goes down along the air flow channel to the filtration component, and goes up after being filtered by the filter component and is released via the mouthpiece component. As the vapor is filtered by the filter component, harmful substances in the vapor are greatly reduced, and also cool the vapor and the whole device, so as to enable the device to be more suitable for using.

When the baking component is fixedly connected to the filter component, as shown in  FIG. 8 , moreover, a center of the filter component is clipped to a center of the baking component, the positive electrode  26  of the end portion of the baking component is butted with the power supply positive electrode  28  of the filter component; the negative electrode  25  of the baking component is butted with the power supply negative electrode  27  of the filter component; the NTC electrode I  29  of the baking component is butted with the sensor electrode of the filter component; the NTC electrode II  30  is butted with the power supply positive electrode  28  of the filter component, and the power supply positive electrode  28  is shared by the NTC electrode II  30  and the positive electrode  26 . 
         [0036]    A silicon seal is provided at a joint between the baking component and the filter component; the mouthpiece component is in a threaded connection to the baking component, and a silicon seal is provided at a joint between the baking component and the mouthpiece component, so as to ensure seal of channels except the normal air flow channel, so that the filtrate is not leaked and the vapor is not leaked in the channels except the air flow channel. As shown in  FIG. 6 , after the filter component  300  disengages with the baking component, an open state is formed above the external pipe  16  and the filter pipe  15  so as to form a injection hole  23 ; in this way, a filtrate  24  can be added into the third space  19  via the injection hole, and the filtrate flows to the second space  18  via the through hole on the bottom part of the filter pipe. To prevent the filtrate from entering the first space via the through hole on the air outlet pipe  14  as much as possible, the amount of the filtrate should be controlled not to exceed the height of the through hole on the air outlet pipe  14 . 
         [0037]    By means of the foregoing implemented tobacco baking device, vapor generated by baking tobacco is filtered by liquid, so as to greatly reduce particle substances in the vapor, thereby reducing harms of smoking; the baking component is in a detachable connection to other components, so as to facilitate replacing components of the baking component and adding the filtrate for the filter component; multiple seal rings are provided at a joint between components in the entire tobacco baking device, so as to ensure that vapor is not leaked via connection seams between the components. 
         [0038]    Preferable embodiments of the present disclosure are described above with reference to the accompanying drawings, and the embodiments are not intended to limit the scope of claims of the present disclosure. Any modification, equivalent replacement, or improvement that does not depart from the scope and essence of the present disclosure and is made by a person skilled in the art should fall within the scope of claims of the present disclosure.
