Detailed Description

A cigarette filter device, as shown in figures 1 to 3, comprises a housing 1 and a housing cover 2 covering the open end of the housing 1; a filtering chamber 3 is arranged in the shell 1; a smoking port 4 and a cigarette jack 5 are arranged on the shell cover 2, a horizontal inner cavity is arranged in the shell cover 2, a switch 10 is horizontally inserted into the inner cavity, the switch comprises a guide cavity inserted into the inner cavity on the shell cover 2 and a rotating handle driving the guide cavity to rotate relative to the inner cavity, the guide cavity is divided into a plurality of small cavities 7 through partition plates 6, air inlets are respectively arranged on the small cavity 7 at the head part and the small cavity 7 between the small cavity 7 at the head part and the small cavity 7 at the tail part, air outlets communicated with the filtering cavity 3 are respectively arranged on the small cavity 7 at the tail part and the small cavity 7 between the small cavity 7 at the head part and the small cavity 7 at the tail part, the air outlets on the small cavity 7 at the tail part are communicated with the smoking port 4, the air inlets on the small cavity 7 at the head part are communicated with the cigarette jack 5, guide pipes 8 are respectively communicated with each air inlet, and each guide pipe 8 is inserted into the bottom, when the switch 10 is in an open state, the air inlet holes on the small cavity 7 at the head part of the guide cavity are communicated with the cigarette insertion holes 5, the air outlet holes on the small cavity 7 at the tail part are communicated with the smoking holes 4, all the air inlet holes are communicated with the guide tube 8, and all the air outlet holes are communicated with the filtering cavity 3. A traditional cigarette holder can be connected to the smoking port 4, and a hose can be connected to the smoking port for smokers to smoke. There may be one or more filtering chambers 3, such as two, three, four or five, etc., according to the actual requirement. Water can be directly placed in the filtering chamber 3 to be used as a purifying filtering object, and sponge with water can also be placed in the filtering chamber 3 to be used as a filtering purifying object.

Two filtering chambers 3 are arranged and are separated by a chamber partition plate 11, a gap is arranged between the bottom of the chamber partition plate 11 and the bottom surface of the shell 1, one filtering chamber 3 is communicated with an air outlet hole on a small chamber 7 connected with a smoking port 4, and the other filtering chamber 3 is used for inserting all guide pipes 8; or the number of the filtering chambers 3 is consistent with that of the small chambers 7, the filtering chambers are separated by the chamber partition plates 11, the filtering chambers 3 are in one-to-one correspondence with the small chambers 7, a space is reserved between the bottom of each chamber partition plate 11 and the bottom surface of the shell 1, and each guide pipe 8 is inserted into the corresponding filtering chamber 3. Through setting up cavity baffle 11, and cavity baffle 11 stretches into shell 1 bottom, leaves the interval that the air feed bubble just passed through between the two, after the bubble passes through the space between cavity baffle 11 and the 1 bottom surface of shell, then can rise by buoyancy, get into once more and correspond little cavity 7, go on coming next time, avoid directly by the direct smoking mouth 4 that flows out of the filter chamber 3 that smoking mouth 4 corresponds, further reduce the volume of tar in the smog and the temperature of smog by a wide margin.

A sealing ring is arranged between the switch 10 and the shell 1, so that the air tightness inside the shell 1 is ensured, and the purified objects inside the shell 1 are prevented from flowing out.

The bottom surface of the smoking port 4 is in a concave arc shape or a conical shape, the middle part of the bottom surface is provided with a through hole communicated with the corresponding small cavity 7, and the bottom surface is also provided with a ball 9. Because the bottom surface of the smoking port 4 is in the shape of an inwards concave arc or a cone, the ball 9 can be blocked at the through hole at last no matter how the ball rolls, when a smoker inhales at the smoking port 4, the ball 9 is sucked up by suction force and the through hole is exposed, so that smoke can flow out of the through hole to the smoking port 4 for people to inhale, and after the smoker looses the mouth, the ball 9 is not stressed, the through hole is blocked again, the smoke is prevented from overflowing, one-way air outlet is realized, and the overflow of second-hand smoke is effectively avoided.

The filter chamber 3 is circular or oval. The circular or oval filter chamber 3 is adapted to cooperate with an O-ring seal so that the cigarette filter unit as a whole is well sealed when the cover 2 is closed.
