Description

Technical Field

[0001] The utility model relates to the technical field of tobacco pipes, in particular to a double-filter tobacco pipe. Background Art

[0002] There are many filter pipes on the market, and the water in them can be used to filter out fine dust in cigarette smoke, such as asbestos particles, tar and nicotine that are harmful to human lungs. However, most existing filter pipes are large in size, and are usually bent to prevent the water from flowing out. These shortcomings make the filter pipes difficult to carry. In addition, the existing filtering method usually has only one-stage filtering, and the cigarette smoke contained in the bubbles does not fully contact with the water, so it is inevitable that some fine dust will enter the human lungs and be deposited.

The tobacco pipe body 1 is provided with a filter cavity 4, that is, the tobacco pipe body 1 is hollow and has an upper opening. The tobacco pot 2 is mounted on the tobacco pipe body 1. The tobacco cavity on the tobacco pot 2 for filling tobacco is a conical shape with a large top and a small bottom. The tobacco pot 2 is provided with a tobacco inlet channel 5 connected to the filter cavity 4 of the tobacco pipe body 1. The tobacco pipe handle 3 is mounted on the side of the tobacco pipe body 1, and the tobacco pipe handle 3 is provided with a filter cavity 4 connected to the tobacco pipe body 1. 4 is connected to the smoke outlet channel 6. For the convenience of carrying, the pipe handle 3 can be designed as a straight rod shape; an oil removal channel 7 is provided between the smoke inlet channel 5 and the smoke outlet channel 6. The oil removal channel 7 divides the filter chamber 4 into a pre-filter chamber and a post-filter chamber, and an activated carbon filter device 8 is installed in the smoke outlet channel 6. The activated carbon filter device 8 is an activated carbon filter element. The path formed by the smoke inlet channel 5, the pre-filter chamber, the oil removal channel 7 and the post-filter chamber is a U-shaped path from top to bottom and then upward. The smoke outlet channel 6 is connected to the post-filter chamber. When in use, tobacco is filled in the smoke pot 2, and when the tobacco is lit and the user performs a smoking operation, the smoke passes through the oil removal channel 7 and the activated carbon filter device 8 located on the flow path in turn, realizing double filtering of the smoke, significantly improving the filtering effect of harmful substances (tar, nicotine and large particles of smoke, etc.) in the smoke, and effectively reducing the harm of smoking to the health of users. Compared with the water filtration structure, it has the advantages of being easier to carry and improving the taste.

[0031] As attached Figure 2 , 4 As shown, the oil removal channel 7 is a spirally extending channel. When the smoke passes through the spirally extending channel, the tar in the smoke will be adsorbed on the inner wall of the oil removal channel 7, and the spiral channel has a large stroke, which can effectively remove the tar.

[0032] As attached Figure 2 , 4As shown, the inner end of the cigarette pot 2 is provided with a cylinder 9 extending in the axial direction, and the bottom end of the cylinder 9 is not fitted with the inner bottom end of the filter chamber 4. The outer circumferential protrusion of the cylinder 9 is provided with a spirally extending retaining rib 10, and the outer contour of the retaining rib 10 is tightly fitted with the inner wall of the filter chamber 4 to achieve sealing of the fitting surface, so that the oil removal channel 7 is formed between the retaining rib 10 and the inner wall of the filter chamber 4. An independent and closed oil removal channel 7 is formed between the retaining rib 10 on the cylinder 9 and the inner wall of the filter chamber 4. The openings at both ends of the oil removal channel 7 are connected with the front section and the rear section of the filter chamber 4. The tar adsorbed in the oil removal channel 7 will flow along the oil removal channel 7 to the bottom of the filter chamber 4. It not only has a good filtering effect, but also is very convenient to process and is conducive to production.

[0033] As attached Figure 4 As shown, the upper and lower sides of the cross section of the retaining rib 10 respectively form an obtuse angle with the outer surface of the cylinder 9 (the cross section can be approximately an isosceles trapezoid). This design is not only convenient for processing, but also more conducive to subsequent cleaning.

[0034] As attached Figure 2 , 4 As shown, the bottom end of the cylinder 9 is provided with a flared opening 11 which is small at the top and large at the bottom, and the small end of the flared opening 11 is connected to the inner end of the smoke inlet channel 5. This design can not only ensure the patency of the smoke inlet channel 5, but also reduce the weight of the entire pipe, making it easier to carry.

[0035] As attached Figure 4 As shown, the cigarette pot 2 is threadedly connected to the open end of the pipe body 1, and the cigarette pot 2 is provided with a first limiting flange 12 that abuts against the upper end of the pipe body 1 and is used to limit the axial travel of the cigarette pot 2, that is, the open end of the pipe body 1 has an internal thread, and the cigarette pot 2 has an external thread that matches the internal thread. The cigarette pot 2 and the pipe body 1 are assembled in a threaded connection, which is very convenient for disassembly and assembly, and is conducive to early assembly and later cleaning operations.

[0036] As attached Figure 2 As shown, the side of the pipe body 1 is provided with a screw hole 13 connected to the filter chamber 4, and one end of the pipe handle 3 is threadedly connected to the screw hole 13, that is, one end of the pipe handle 3 has an external thread that matches the screw hole 13, and the pipe body 1 is provided with a second limiting flange 14 for constituting an axial travel limit for the pipe handle 3 at a position corresponding to the screw hole 13. The pipe body 1 and the pipe handle 3 are detachable structures connected by threads, which are very convenient to disassemble and assemble, and are easy to store and carry when the two are separated.

[0037] As attached Figure 2As shown, the pipe handle 3 includes a first handle body 15 and a second handle body 16, which are detachably connected together, and the first handle body 15 and the second handle body 16 are respectively provided with a first channel 17 and a second channel 18, which are combined to form the smoke outlet channel 6, and the activated carbon filter device 8 is clamped between the first handle body 15 and the second handle body 16. The pipe handle 3 adopts a detachable structure, and the activated carbon filter device 8 is clamped between the first handle body 15 and the second handle body 16, which is convenient for the installation of the activated carbon filter device 8 in the early stage and the replacement of the activated carbon filter device 8 in the later stage.

[0038] As attached Figures 2 to 4 As shown, the end of the first handle body 15 close to the second handle body 16 is provided with a first positioning groove 19 connected to the first channel 17, and the end of the second handle body 16 close to the first handle body 15 is provided with a second positioning groove 20 connected to the second channel 18. The first positioning groove 19 and the second positioning groove 20 are combined to form a positioning cavity 21 adapted to the shape of the activated carbon filter device 8. The activated carbon filter device 8 is arranged in the positioning cavity 21. The activated carbon filter device 8 and the positioning cavity 21 can be designed to be cylindrical. This design can stably install the activated carbon filter device 8, thereby ensuring a good filtering effect of the activated carbon filter device 8. In addition, the first positioning groove 19 can be set separately, and the activated carbon filter device 8 is pressed into the first positioning groove 19 by the second handle body 16, and the second positioning groove 20 can also be set separately, and the activated carbon filter device 8 is pressed into the second positioning groove 20 by the first handle body 15.

[0039] As attached Figure 2 As shown, the first handle body 15 and the second handle body 16 are connected together by threaded matching. An internal thread can be set on the first handle body 15, and an external thread matching the internal thread can be set on the second handle body 16.
