The following advantages are associated with the heating cup assembly and the hookah of the disclosure: the heating cup assembly comprises a first cup provided with a second side wall; the condensate flows along the second side wall and re-enters the first cup, which prevents the condensate from overflowing in the hookah. Furthermore, the heating cup assembly is detachable, portable, and easy to clean.
In the drawings, the following reference numbers are used: 5. Second cup; 10. Heating cup assembly; 20. Heater; 29. First cup; 201. Top concave portion; 501. Second cavity; 502. Third side wall; 503. Flange; 504. Second bottom wall; 2901. First side wall; 2902. First cavity; 2903. Second side wall; 2905. First end; 2906. Second end; 2907. Third end; 2908. Fourth end; and 2909. First bottom wall.
To further illustrate the disclosure, embodiments detailing a heating cup assembly and a hookah of the disclosure are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
Referring to
In certain examples, the heater 20 comprises a top concave portion 201 surrounded by a fourth side wall. The hookah further comprises a coil wrapped around the fourth side wall. The heating cup assembly 10 is detachably connected to the concave portion 201 to allow for convenient assembly, disassembly, and cleaning of the hookah. Furthermore, the heating cup assembly need not be limited to the top concave portion 201. When energized, the coil produces an electromagnetic field which can heat the heating cup assembly 10 and transfer the heat to the tobacco materials. The tobacco materials produce smoke through high-frequency electromagnetic induction.
The water jar is detachably connected to the heating cup assembly 10 to allow convenient assembly, disassembly, and cleaning of the hookah.
