[0009] Also provided is a high frequency heating unit, comprising a magnetic induction coil and a battery, wherein the battery comprises a power panel comprising an LC circuit configured to convert a boosted DC voltage and current into an alternating current; when the alternating current passes through the magnetic induction coil, an alternating magnetic field is generated.

[0010] The high frequency heating unit further comprises a hollow handle and a hollow annular structure; the battery is disposed in the hollow handle, and the magnetic induction coil is disposed in the hollow annular structure.

[0011] A hookah comprises a heating cup and a high frequency heating unit; the high frequency heating unit comprises a magnetic induction coil and a battery; the battery comprises a power panel comprising an LC circuit configured to convert a boosted DC voltage and current into an alternating current; when the alternating current passes through the magnetic induction coil, an alternating magnetic field is generated; when in use, the high frequency heating unit is disposed around the heating container; in a power-on state, the heating container is configured to produce heat under the action of the high frequency heating unit to heat a tobacco material and produce smoke.

[0012] The hookah further comprises a water filter; when in use, the smoke is filtered by the water filter and then inhaled by a user. FIG. 1 is a sectional view of a heating cup in accordance with one embodiment of the disclosure; and FIG. 2 is a schematic diagram of a heating cup in accordance with one embodiment of the disclosure; FIG. 3 shows a connection of a heating cup and a water filter in accordance with one embodiment of the disclosure; FIG. 4 is a sectional view of a high frequency heating unit in accordance with one embodiment of the disclosure; and FIG. 5 shows a connection of a heating cup and a high frequency heating unit in accordance with one embodiment of the disclosure.

[0013] To further illustrate, embodiments detailing a heating cup and a high frequency heating unit are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

[0014] Tobacco materials refer to smoke oil, tobacco, tobacco and other materials used to produce smoke.

[0015] The disclosure provides a heating cup in combination with a water filter for use.

[0016] Specifically, as shown in FIGS. 1-2, the heating cup comprises an air inlet nozzle 1, a heating container 2, a metal conductor 3 inlaid in the heating container 2. The air inlet nozzle 1 is disposed on the top of the heating container 2. The metal conductor 3 is inlaid in the heating container 2 and when being heated, the metal conductor exchanges heat with the heating container 2 to heat the tobacco material in the heating container 2. The air inlet nozzle 1 is made of ceramic material, and the heating container 2 is made of glass inlaid metal conductor 3.

[0017] The air inlet nozzle 1 is made of ceramic, quartz, crystal, mica and jade, which is thermally insulated and will not burn the hand in case the hand touches the air inlet nozzle.

[0018] The heating container 2 is entirely a metal or a part of it is a metal, or glass material or ceramic, quartz, crystal, mica, jade material inlaid with a metal.

[0019] As shown in FIG. 3, provided is a water filter used in combination with the heating cup.

[0020] As shown in FIG. 4, provided is a high frequency heating unit used in combination with the heating cup. The high frequency heating unit comprises a magnetic induction coil 501 and a battery 502; the battery 502 comprises a power panel comprising an LC circuit configured to convert a boosted DC voltage and current into an alternating current; when the alternating current passes through the magnetic induction coil, an alternating magnetic field is generated. The high frequency heating unit further comprises a hollow handle 503 and a hollow annular structure; the battery 502 is disposed in the hollow handle, and the magnetic induction coil 501 is disposed in the hollow annular structure.

[0021] As shown in FIG. 5, in use, a user holds the hollow handle 503 of the high frequency heating unit. The high frequency heating unit comprises a heating part 504 corresponding to the metal conductor 3 inlaid in the heating container 2. In a power-on state, the heating container 2 produces heat under the action of the high frequency heating unit to heat a tobacco material and produce smoke. The air enters the heating container 2 via the air inlet nozzle 1 and drives the produced smoke to submerge into the water of the water filter 4 via the second air passage of the heating container 2, where the smoke is filtered, flows to a smoke outlet 101 of the water filter, and is inhaled by a user.

[0022] It will be obvious to those skilled in the art that changes and modifications may be made, within the scope of the appended claims.
