Detailed ways

All of the features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner other than mutually exclusive features and/or steps.

Any feature disclosed in the specification, including any additional claims, abstract and drawings, may be replaced by other equivalents or alternative features, unless otherwise stated. That is, unless specifically stated, each feature is only one example of a series of equivalent or similar features.

As shown in FIG. 1 to FIG. 3, the cigarette holder is inserted into the cigarette body, and the cigarette holder absorbs water in the flue gas generated by heating and not burning through an automatic filtering mechanism, and the automatic filtering mechanism is a filter cotton 3 disposed in the cigarette holder. The water in the flue gas enters the filter cotton 3.

The automatic filtering mechanism further includes a gas flow tube 2 and a suction needle tube 6. The suction needle tube 6 is disposed at the bottom of the entire cigarette holder, and is inserted into the tobacco body to suck the smoke generated by heating and not burning into the cigarette holder. In order to ensure that the flue gas can pass through the filter cotton, we put the filter cotton into the air flow tube, so that the flue gas out of the air flow tube can filter the water in the flue gas.

In this embodiment, the cigarette holder comprises a straw 4 and a nozzle sleeve 1, and the nozzle sleeve 1 is mounted on the top of the nozzle for sucking; the nozzle sleeve 1 seals the top open end of the nozzle, and the smoke is sucked out from the nozzle. The gas flow tube 2 and the filter cotton 3 are placed in the suction tube 4. One end of the suction needle tube 6 is inserted into the straw, the output end of the suction needle tube is in communication with the intake passage in the suction tube, the inlet passage is connected to the input end of the air flow tube, and the output end of the air flow tube is connected to the nozzle sleeve.

Wherein, the outer end of the bottom of the straw is provided with a sealing ring 5, and the straw is loaded into the body through the sealing ring 5. Ensure the sealing of the mouthpiece and the body of the cigarette.

Among them, the filter cotton 3 is made of water absorbing material, the air flow tube 2 is made of PP material, the suction needle 6 is made of stainless steel material, and the cigarette holder is made entirely of PC material. The above materials are only a preferred material selection in this embodiment, and replacement with other materials is not excluded.

working principle:

The flue gas generated by heating and not burning enters into the straw from the pipette needle and is directly sprayed on the filter cotton. The moisture in the flue gas is absorbed by the filter cotton, and the remaining flue gas enters the nozzle sleeve from the gas flow tube and then enters the oral cavity. Used to smoke. The smoke coming out does not contain water and enhances the taste.

The invention has the beneficial effects that the invention can rapidly cool the flue gas which is not burned by heating, and the cracked water generated by heating the non-burning tobacco can be sufficiently absorbed to improve the mouthfeel in the smoke suction port.

The above is only the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of by the creative work are included in the scope of the present invention. Therefore, the scope of the invention should be determined by the scope of the invention as defined by the appended claims.
