Low-temperature smoking set

Abstract

The invention discloses a low-temperature smoking set, which comprises a housing. The housing is internally provided with a heating body and a driving assembly for driving the heating body to be inserted into or withdrawn from a heating cavity. The driving assembly comprises a direct-current motor, a Hall switch, a lead screw and a sliding block connected to the outer side of the lead screw in a sleeving mode, wherein the lead screw is in transmission connection with the direct-current motor through a speed reducer, the sliding block is installed on a sliding rail in the housing in a sliding mode and connected with the heating body, the direct-current motor and the Hall switch are electrically connected with a PCB in the housing, and an output shaft of the direct-current motor is providedwith a magnetic piece which synchronously rotates with the motor and is used for triggering the Hall switch. According to the invention, through the magnetic piece moving synchronously with the motorand the magnetic induction Hall switch, the signal of the number of turns of the motor is obtained; the linear displacement distance of the heating body is accurately driven based on the relationshipbetween the rotation turn number of the motor and the transmission ratio value of a reduction gearbox and the relationship between the screw pitch value of the lead screw and the displacement distancerequired by the heating body, so that accurate control over the displacement of the heating body is achieved.

AI Technical Summary

Problems solved by technology

[0003] The heating element is placed inside the tobacco for heating. After the tobacco is baked and heated, part of the substance volatilizes, and the tobacco shrinks and attaches to the heating element under the action of the smoking airflow. Pulling out the cigarette directly will cause the tobacco waste to stick to the smoking set. The industry products are pushed out manually. The method of separating the tobacco from the heating element and then pulling out the cigarette, or turning the cigarette after smoking is completed and then pulling out the cigarette, is cumbersome to operate and has a poor user experience. The existing low-temperature smoking set with the function of retracting the heating element has a large impact on the movement of the heating element. The distance cannot be precisely controlled
