Abstract

A hookah, including a high-frequency heating component and a filter assembly. The high-frequency heating component includes a conductive cup and a magnetic induction coil. The conductive cup is disposed in the magnetic induction coil and configured to accommodate a tobacco material. When in use, an alternating current is introduced to the magnetic induction coil, and a magnetic induction effect is generated, so that the conductive cup is heated and the heat is transferred to the tobacco material whereby the tobacco material is heated and smoke is produced. The smoke is filtered in the filter assembly and inhaled by a user.

First claim

The invention claimed is:

1. A hookah, comprising a body, a ceramic cup, a high-frequency heating component, and a filter assembly; wherein:
the high-frequency heating component comprises a conductive cup and a magnetic induction coil;
the conductive cup is disposed in the magnetic induction coil and configured to accommodate a tobacco material;
when in use, an alternating current is introduced to the magnetic induction coil, and a magnetic induction effect is generated, so that the conductive cup is heated and the heat is transferred to the tobacco material whereby the tobacco material is heated and smoke is produced; the smoke is filtered in the filter assembly and inhaled by a user;
the conductive cup and the magnetic induction coil are disposed in one side of the body;
the ceramic cup is disposed between the conductive cup and the magnetic induction coil;
the filter assembly comprises a straight glass tube, an adapter, a curved glass tube, and a snuff bottle; the snuff bottle is adapted to receive the smoke via the adapter and curved glass tube, and the snuff bottle is adapted to discharge the smoke via the straight glass tube; and
the conductive cup is a glass cup with an inlaid metal; and
a space between the conductive cup and the ceramic cup is adapted to convey the smoke through a bottom opening of the ceramic cup into an inner space of the adapter.

2. The hookah of claim 1 , wherein the hookah further comprises a temperate sensor; when a temperature of the hookah reaches a set maximum temperature, the temperate sensor transmits a temperature signal to an over-temperature protection circuit of a control panel and the control panel reduces an output power of the hookah.

3. The hookah of claim 2 , wherein the temperature sensor is disposed on a bottom of the ceramic cup.

4. The hookah of claim 1 , wherein the hookah further comprises an air guide cover; the air guide cover comprises a hollow part with a first opening and a second opening smaller than the first opening; and the second opening is disposed in the conductive cup.

5. The hookah of claim 4 , wherein the air guide cover is a ceramic.

6. The hookah of claim 1 , wherein the hookah further comprises an air guide tube and an airflow sensor; the air guide tube is disposed on the adapter for air conduction; the airflow sensor is disposed on the air guide tube; when an airflow passes through the air guide tube, the airflow sensor triggers the high-frequency heating component to work.

7. The hookah of claim 1 , wherein the hookah further comprises a mouthpiece; the mouthpiece is a hollow hemispherical glass structure comprising an opening.
