    Abstract: A heating cup assembly includes a first cup. The first cup includes a first cavity, a first side wall, and a second side wall. The first cavity is surrounded by the first side wall. The first side wall includes a first end and a second end. The second side wall includes a third end and a fourth end. The second end and the third end are disposed in one horizontal plane. The second side wall is in the shape of a truncated cone, and a diameter of the third end is less than that of the fourth end.

    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.

    Abstract: A method for constant torque control of an EC motor of a ventilation system includes: defining a maximum speed spd_max_ref and a minimum speed spd_min_ref of an electronically commutated motor (ECM) within a constant-torque operation range; by using a proportional integral (PI) controller, calculating an upper reference torque T_ref_up with the maximum speed spd_max_ref as a first reference speed, and calculating a lower reference torque T_ref_low with the minimum speed spd_min_ref as a second reference speed; and T_ref_up>T_ref_low; receiving an externally input torque command Tcom; comparing the torque command Tcom, the upper reference torque T_ref_up, and the lower reference torque T_ref_low to determine a target torque Tact; and controlling the ECM to operate in a constant torque mode under the target torque Tact.
