Smokeless Cigarette Filter Device

1. Field of the Invention

The instant invention relates generally to smoking devices and more specifically it relates to a smokeless cigarette filter device.

2. Description of the Prior Art

Numerous smoking devices have been provided in prior art. For example, U.S. Pat. Nos. 2,108,218 to Stultz; 2,620,804 to McMahon; 4,148,328 to Fox and 4,790,332 to Wallace all are illustrative of such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.

A smoking device comprising a rectangular metallic casing that includes a bottom, end walls and side walls. The top of the casing is open and the side walls have perforations therein in substantially the upper halves of the walls. A neck projects inwardly from one of the end walls. The neck projects into the perforated part of the casing. The end wall has an opening in its lower half. A drawer passes through the opening into the unperforated part of the casing. A holder for cigarettes and cigars has a reduced part passing through the neck and a head located in the perforated part of the casing. A tube is connected with the projecting portion of the reduced part. A mouthpiece is on the free end of the tube. A substantially anticlinal perforated cover fits over the upper open end of the casing. The internal walls of the casing and cover are plain and unobstructed with the exception of the neck.

A light-tight cigarette holder comprising a mouthpiece adapted to receive a cigarette. An elongated hollow body member has one end secured to the mouthpiece and is arranged to enclose a cigarette held in the mouthpiece. A housing has one end open and has an end wall substantially closing the other end thereof arranged so that the open end is secured to the other end of the body. The end wall of the housing is formed with an air intake opening. A baffle member is mounted in the housing adjacent the opening and in light shielding relation thereof relative to the remainder of the interior of the housing. A match striking surface is carried by the baffle member. The housing is formed with an opening adjacent the match-striking surface for the admission of a match.

A base member has a recess in its top surface, and the bottom wall of the recess has a vertical socket arranged to hold a cigarette upright. A flexible tube is connected into the base member for communication with the socket and has a smoking tip whereby a cigarette in the base member can be smoked by a person remote from the cigarette. A hollow lid is employed which can be locked in place on the base member to prevent access to the cigarette being smoked. The lid has apertures placed at selected upper and lower portions therein to provide a draft ventilation for cigarette smoke.

A hand-held device eliminates smoke generated from cigarette smoking. This cigarette package-sized device completely encloses a cigarette while it is being smoked and provides two mouthpieces, one for inhaling and the other for exhaling smoke into the device. All smoke passes through two filters, a particulate filter and an odor filter, before being discharged into the ambient atmosphere.

A primary object of the present invention is to provide a smokeless cigarette filter device that will overcome the shortcomings of the prior art devices.

Another object is to provide a smokeless cigarette filter device that will allow cigarette smokers to light up whenever and wherever they desire without the worries of harming the health of others or contributing to air pollution.

An additional object is to provide a smokeless cigarette filter device that totally encapsulates the cigarette and filters harmful first and second hand smoke to prevent the smoke from ever reaching the outside air, since the cigarette is lit, smoked and extinguished within the device.

A further object is to provide a smokeless cigarette filter device that is simple and easy to use.

A still further object is to provide a smokeless cigarette filter that is economical in cost to manufacture.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 6 illustrate a smokeless cigarette filter device 10, which consists of a barrel 12 fabricated out of molded, heat resistant durable material. A structure 14 on a first end 15 of the barrel 12 is for covering the mouth and nose of a smoker. An element 16 is for holding a cigarette 18 within the barrel 12, so that a butt end 20 of the cigarette can enter the mouth and nose covering structure 14. A component 22 is for lighting a distal end 24 of the cigarette 18 within the barrel 12 when the smoker inhales. An assembly 26 is on a second end 27 of the barrel 12, for filtering harmful first and second hand smoke coming from the lit cigarette 18 and the smoker, so as to prevent the smoke from ever reaching the outside air. An apparatus 28 is for extinguishing the cigarette 18 within the barrel 12, when the smoker is done smoking the cigarette 18.

The mouth and nose covering structure 14 is a mouth and nose cup mask 30, molded of pliable material that will snugly conform to the face of the smoker. The mouth and nose cup mask 30 includes a collar 32 that is removable from the first end 15 of the barrel 12 for cigarette 18 placement and cleaning.

The mouth and nose cup mask 30 further contains a plurality of one way inlet valves 34, to allow air to enter, prevent the escape of smoke filled air while the smoker is smoking and prevent the mouth and nose cup mask 30 from collapsing when it is pressed against the smoker's face. The mouth and nose cup mask 30 further includes a cigarette guide and exhalation vent 36, being funnel shaped and having a centered cigarette guide sleeve 38 to receive the butt end 20 of the cigarette 18 surrounded by a plurality of vent holes 40. The vent holes 40 are for allowing exhaled smoke from the mouth of the smoker after it is drawn directly from the butt end 20 of the cigarette 18, to be blown back into the device 10. The vent holes 40 are also for allowing air to freely enter the device 10, while the mouth and nose cup mask 30 is not against the face of the smoker for the filtration of first hand smoke.

The cigarette holding element 16 contains a clamp 42, for engaging the butt end 20 of the cigarette 18. The clamp 42 is removable and interchangeable for cleaning purposes. The installation of a smaller clamp is to facilitate a smaller diameter cigarette 18. A stem 44 extends from the clamp 42. A spring loaded thumb lever 46 is connected to the stem 44, to thrust the butt end 20 of the cigarette 18 into the guide sleeve 38 and return to its original position when released.

The lighting component 22 consists of a slide member 50 formed on the barrel 12 that has an aperture 48 below the distal end 24 of the cigarette 18. A cigarette lighter 52 has a slide railing 53, to mate with the slide member 50. A spark ignitor 54 has a flame opening 56 in the cigarette lighter 52 that is positioned within the aperture 48 directly under the distal end 24 of the cigarette 18. A plunger 58 in the cigarette lighter 52 operates the spark ignitor 54. A butane refill nozzle 60 is for refueling the cigarette lighter 52.

The filtering assembly 26 includes an ash screen 62 insertable into the second end 27 of the barrel 12, for collecting ashes from the lit distal end 24 of the cigarette 18. A filter disc 64 is also insertable into the second end 27 of the barrel 12 behind the ash screen 62 and is capable of filtering the cigarette smoke from the air within the barrel 12. An exhaust assembly 66 is removable from a collar 68 at the second end 27 of the barrel 12, to replace the ash screen 62 and the filter disc 64 when needed. The exhaust assembly 66 will expel filtered air into the outside air.

The ash screen 62, as shown in FIGS. 1 and 6, is conical shaped. The point is inserted facing the lit distal end 24 of the cigarette 18, which will direct the ashes toward a rim of the screen 62 to allow its middle portions to remain cleaner longer.

The exhaust assembly 66 contains a housing 70, having an open end 72 with an internal rim 74 to act as a stop for the filter disc 64. The filter disc 64 rests on the rim 74, when the open end 72 of the housing 70 fits over the collar 68 of the barrel 18. The housing 70 has a plurality of vent holes 75 located in a rear portion thereof, to allow the filtered air to be expelled therefrom. A motor 76 with a shaft 78 is mounted within the housing 70, so that the shaft 78 extends towards the open end 72 of the housing 70. A plurality of fan blades 80 are affixed onto the shaft 78 within the open end 72 of the housing 70, to be rotated by the shaft 78 for extracting the filtered air through the filter disc 64. A battery compartment 82 is located in the rear portion of the housing 70, for retaining at least one battery 84 therein for supplying power to the motor 76. A switch 86 is mounted on a distal end of the battery compartment 82, to turn the motor 76 on and off.

The extinguishing apparatus 28 consists of the barrel 12 having a top longitudinal slide track 88 above the entire length of the cigarette 18. A hinged lever 90 has two pivot pin followers 92, to ride in the slide track 88. The lever 90 extends above the slide track 88. An arm 94 extends from the lever 90 within the barrel 12. A beveled pan shaped fireproof disk 96 is connected to the arm 94. When the lever 90 is manually raised to a vertical position, the arm 94 will swing the fireproof disk 96 down into a vertical position to be perfectly aligned with the lit end 24 of the cigarette 18, for movement to and from the lit end 24 of the cigarette 18 to stamp it out. A ribbon seal 98 covers the slide track 88, to prevent the escape of cigarette smoke during the lighting process.

FIG. 6 shows a modified battery compartment 82a under the housing 70 instead of to the rear of it. A cover 100 fits over an open end 102 of the battery compartment 82a, to keep the batteries 84 therein. In this way, the motor 76 in the housing 70 and the battery compartment 82a can be made larger to function better in the device 10.
