Background

Smoking products are popular with consumers due to their unique flavor. The smoking step is generally to place the raw materials in a smoking chamber, then to make the smoking material slowly burn or incompletely burn to generate smoke, and to conduct the smoke generated by burning the smoking material to the smoking chamber through a smoking device, so that the food is dried at a certain temperature and absorbs the smoke of the wood. After a period of smoking, the raw material will have a unique smoked flavor.

During smoking, hard wood is usually adopted as a smoking material, harmful substances such as benzopyrene and the like can be generated when the smoking material is incompletely combusted, after the raw material is smoked by smoke, benzopyrene invades along with smoke and remains in the raw material, the more smoke is generated by the smoking material, and the more residual quantity of the benzopyrene in the raw material is. Benzopyrene has carcinogenicity, and smoking products containing harmful substances such as benzopyrene have adverse effects on human bodies.

The smoke outlet 12 extends to the outside of the smoking gun body 1.

Referring to fig. 1, a smoking cover 7 is disposed on one side of the smoking gun body 1. The smoking cover 7 is hemispherical and hollow. The side wall of the smoking cover 7 is provided with a smoke inlet 71. The smoke inlet 71 penetrates through the side wall of the smoking cover 7. The outer wall of the smoking cover 7 close to the smoke inlet 71 is provided with a sealing plug 711 matched with the smoke inlet 71. A rubber tube 18 is connected between the smoke inlet 71 and the smoke outlet 12 of the smoking gun body 1. The two ends of the rubber tube 18 are respectively sleeved outside the smoke outlet 12 and the smoke inlet 71. The side wall of the smoking cover 7 opposite to the smoke inlet 71 is provided with a smoke outlet 72. The smoke outlet 72 extends through the side wall of the smoking cover 7. Similarly, the outer wall of the smoking cover 7 near the smoke outlet 72 is provided with a sealing plug 711 matching with the smoke outlet 72.

One side of the fumigating cover 7 far away from the fumigating gun body 1 is provided with a gas collection assembly, and the gas collection assembly comprises an air exhaust part and an air bag 81. The exhaust part adopts an exhaust fan 8. The exhaust fan 8 includes an air suction opening 82 and an air outlet 83. The air suction opening 82 faces the fumigation cover 7, and the air outlet 83 faces the air bag 81 and is communicated with the air bag 81. The rubber tube 18 is also arranged between the air suction opening 82 of the exhaust fan 8 and the smoke outlet 72 of the smoking cover 7. The two ends of the rubber tube 18 are respectively sleeved on the outer walls of the air suction opening 82 and the smoke inlet 71. The air outlet 83 of the exhaust fan 8 is communicated with the air bag 81.

The smoking gun with the filtering function of the embodiment is implemented according to the following principle: the smoking material is put into the fuel cylinder 2 and ignited, the air exhaust fan 17 is started, the smoke generated by the smoking material passes through the filter bin 3, and the water in the filter bin 3 can filter solid particles in the smoke; the smoke flows to the drying box 5 from the filtering bin 3 after being filtered, and is dried by the drying box 5, so that the smoke is dried, and harmful substances adhered to the liquid flow to the adsorption box 6 along with the gas. The activated carbon 66 in the adsorption box 6 can adsorb harmful substances such as benzopyrene in the smoke gas, and the smoke after adsorption flows to the smoking cover 7 through the smoke outlet 12.

Raw materials are placed in the smoking cover 7, the smoke outlet 72 of the smoking cover 7 is opened, and after the smoking cover 7 is filled with smoke, the smoke inlet 71 and the smoke outlet 72 are blocked by the sealing plug 711, so that the smoke can fully smoke the raw materials. After smoking, the sealing plugs 711 of the smoke inlet 71 and the smoke outlet 72 are opened, the smoke outlet 72 is connected with the exhaust fan 8, the exhaust fan 8 is connected with the air bag 81, and the exhaust fan 8 is started to enable smoke in the smoking cover 7 to flow into the air bag 81.

By adopting the mode, the residue of benzopyrene on the smoked product can be reduced, the safety of the smoked product is improved, the harm of the edible smoked product to the human body is reduced, the possibility that the human body inhales smoke when the smoking cover 7 is opened can be reduced, and the damage of the smoke to the human body is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
