Abstract

A hookah including a glass tube and a push rod. The bottom end of the push rod is disposed in the glass tube and is movable in the inner wall of the glass tube when being pushed by force. The tobacco material is loaded in the glass tube and between the bottom end of the push rod and the opening of the glass tube; and smoke produced by the atomization of the tobacco material flows in an air passage of the push rod.

First claim

What is claimed is:

1. A hookah, comprising a glass tube, a push rod having an air passage, and an assistant push rod; the glass tube, the push rod, and the assistant push rod being arranged such that the assistant push rod sleeves only a first half of the push rod which is movably disposed inside the glass tube and configured to move along an inner wall thereof upon an action of the assistant push rod, and a space is formed between a bottom opening of the glass tube and a bottom end of the push rod; wherein,
when in use, tobacco material is loaded both in the glass tube and in the space, and wherein smoke produced by atomization of the tobacco material flows in the air passage of the push rod.

2. The hookah of claim 1 , further comprising a silicone ring, wherein the silicone ring is disposed in a top opening of the assistant push rod and between the assistant push rod and the push rod, so that owing to a frictional force, a movement of the assistant push rod drives the push rod to move.

3. The hookah of claim 2 , further comprising a slidable cylinder, a push button, and a screw, wherein the assistant push rod is disposed in the slidable cylinder; a bottom opening of the slidable cylinder is located in a top opening of the glass tube; the push button extends from a guide groove of the slidable cylinder to abut against a top end of the assistant push rod and is fixed by the screw; the push button moves in the guide groove of the slidable cylinder to control the movement of the assistant push rod.

4. The hookah of claim 3 , further comprising a location pin, wherein the location pin is disposed on the assistant push rod; a plurality of continuous grooves is disposed on an inner wall of the slidable cylinder and matches the location pin for controlling a forward distance of the assistant push rod to ensure an output amount of the tobacco material for each push.

5. The hookah of claim 3 , further comprising an outer air tube, a water-storage glass tube, an inner air tube, and a fixed base, wherein the fixed base is disposed in a top opening of the slidable cylinder; a top end of the push rod is sheathed with a second seal ring disposed in the fixed base; the inner air tube is disposed through the fixed base and communicates with the push rod; the outer air tube sleeves the inner air tube and is fixed on the fixed base; a lower seal ring sleeves the fixed base to seal a bottom opening of the water-storage glass tube; the water-storage glass tube is supported by the fixed base and the outer air tube is disposed in the water-storage glass tube.

6. The hookah of claim 5 , further comprising an inversion valve disposed on a top of the inner air tube and between the inner air tube and the outer air tube to block water in the water-storage glass tube and prevent the water in the water-storage glass tube from entering the inner air tube.

7. The hookah of claim 6 , wherein an outer wall of the outer air tube comprises at least one through hole for smoke discharge.

8. The hookah of claim 7 , further comprising a mouthpiece, a check valve, and a mouthpiece holder, wherein a lower part of the mouthpiece holder comprises a vent hole, and an upper part of the mouthpiece holder is disposed in a top opening of the water-storage glass tube; the lower part of the mouthpiece holder is fixed in a top opening of the outer air tube; the check valve is disposed in the mouthpiece to block reverse air, thus preventing air reversing from the mouthpiece from entering the water storage glass tube; and the mouthpiece is disposed on the mouthpiece holder.

9. The hookah of claim 8 , further comprising a metal tube, wherein after use, the metal tube sleeves the glass tube and the slidable cylinder, and a top end of the metal tube is fixed on the fixed base to protect the glass tube and quench the tobacco material.

10. The hookah of claim 1 , wherein the push rod comprises a hollow structure comprising the air passage and the bottom end of the push rod comprises a plurality of evenly distributed through holes.
