The multiple layers of filters of part can be made of different materials, increase the effect of its filtering.In the present embodiment, filter assemblies may be used also
With the filter assemblies used using existing anti-poison respirator 3.
Preferably, in order to improve the efficiency of filtering, a fan 38 is set at connector 321, it is logical that flue gas can be accelerated
The speed of filter assemblies is crossed, thereby improving filtration efficiency.
Perfuming device includes above-mentioned fan 38, which is arranged in the outside of filter assemblies.Perfuming device further includes
The fragrant atmosphere accommodating cavity 391 of the air outlet of fan 38 is set, and fragrant atmosphere accommodating cavity 391 has air-intake window 392 and outlet air window
393, air-intake window 392 is connected to the air outlet of fan 38, is placed with fragrant atmosphere block 394, in fragrant atmosphere accommodating cavity 391 so as to fan
38 in the process of work, and the fragrance of fragrant atmosphere block 394 is spread apart to come outward.
Second, flue gas processing device is anion generator (not shown), and anion generator, which has, protrudes into the appearance of cigarette 6
It sets room 1 and holds the multiple groups anion electrode in mouth chamber 32.When anion generator works, foot is generated around anion electrode
The anion of amount, anion, which can neutralize rapidly in the flue gas that smoking generates, belongs to burnt cigarette, " secondhand smoke " of cation etc..By negative
Ion generator work generates a large amount of anions in 6 accommodation chamber 1 of cigarette and appearance mouth chamber 32, the flue gas generated to the burning of cigarette 6
Neutralize with the flue gas of smoker's exhalation clear, keeps the air purity being discharged from connector 321 high.Anion generator
Power is according to 6 accommodation chamber 1 of cigarette and holds the flue gas generated in mouth chamber 32 and is selected, it is necessary to assure from can be in air from connection
The whole of harmful substance reached in the flue gas to cigarette 6 before 321 discharge of mouth remove.
As optional embodiment, in order to further ensure the using effect of the utility model, as shown in figure 3, this reality
Further include cigarette storage device 4 with the smoking apparatus that new embodiment provides, flue gas processing device can be replaced with cigarette storage device 4, it can also
Cigarette storage device 4 to be arranged again on the basis of flue gas processing device is arranged.
Cigarette storage device 4 has the tobacco storage cavity for accommodating flue gas, is provided with the disengaging being connected to tobacco storage cavity in cigarette storage device 4
Mouth 41, smoke inlet and outlet 41 are connected to connector 321 by smoke discharging pipe 5, are able to enter storage to hold the flue gas in mouth chamber 32
In smoke chamber.Smoke inlet and outlet 41 be removably connected with second one-way valve 401, drain into Rong Zui for preventing the flue gas in tobacco storage cavity from returning
In chamber 32.
Specifically, second one-way valve 401 is detachably connected with smoke inlet and outlet 41 and smoke discharging pipe 5.In the present embodiment,
