[0014] The beneficial effects of the present invention are as follows: since the shell is in a bucket shape (an inverted cone with a larger top and a smaller bottom), the space inside the shell is divided into a silo and an ash silo by a vertical partition, and both the silo and the ash silo are in a cone shape (a frustum shape) with a larger top and a smaller bottom, the shredded tobacco and mixed materials (other raw materials, if any) put in from the top of the silo automatically fall into the bottom of the silo, and a certain amount of raw materials (shredded tobacco, and auxiliary materials mixed in the shredded tobacco, if any) can be stored, and there is no need to load materials every time you smoke, and the shredded tobacco is continuously deposited at the bottom of the silo, ensuring that as long as there is material in the silo, it can be fed into the combustion chamber by the feeding mechanism, and the ashes (ash) falling from the combustion chamber rotating to the upper part of the silo can automatically fall into the bottom of the ash silo; since a spiral (auger-type) feeding mechanism is provided in the silo, the raw materials at the bottom of the silo can be automatically fed into the combustion chamber located at the feeding station, and the feeding amount can be more accurately controlled by controlling the number of rotations of the screw rod; An ash dropping mechanism cooperating with the combustion chamber is arranged on the upper part of the ash bin, and the ash in the combustion chamber at the ash dropping position can be pushed downward by the push rod of the ash dropping mechanism or the push plate at the end of the push rod, and fall into the bottom of the ash bin, so as to empty the combustion chamber and provide conditions for the next smoking.

DETAILED DESCRIPTION

[0016] See also Figure 1-Figure 3 The bucket-type electronic cigarette includes a shell 10, a combustion chamber 30 and an igniter (ignition module) 37 for igniting the combustion chamber in the smoking position. The shell is conical (cone-shaped) with a larger top and a smaller bottom. A vertical (elevational) partition 16 is provided in the shell to divide the space in the shell into a material bin 19 and an ash bin 18. The combustion chamber is cylindrical and located in the upper part of the shell and is provided with a combustion chamber driving device 35 for driving it to swing horizontally (or rotate). The output shaft (shaft extension) 36 of the combustion chamber driving device faces downward and is connected to the combustion chamber through a corresponding bracket 33. The swing range of the combustion chamber is provided with a feeding station and an ash dropping station 31 ( Figure 1 The combustion chamber is provided with a feeding mechanism for feeding the material at the bottom of the silo into the combustion chamber at the feeding position, and the ash dropping mechanism 40 is provided in the ash silo or not, and the ash dropping mechanism 40 is provided in the ash silo for pushing the material (ash, embers) in the combustion chamber at the ash dropping position out.

[0017] The top of the shell is open, and may be provided with a top cover 12 for covering its top opening, or may be an open top structure without a top cover, so that the internal condition of the shell can be directly observed, and feeding and cleaning are convenient. If necessary, a fixed top plate is also provided on the top of the shell. The side of the shell can be set as a detachable structure, so that it can be opened for inspection and maintenance when necessary. When a top cover is provided, a feeding port 13 is provided on the top cover, and the feeding port is located above the silo (when the top cover is covered on the top opening of the shell according to the setting method), connected to the silo, and used to put materials such as tobacco into the silo. The top cover can be any suitable form such as a flip cover, a buckle cover and a sliding cover. When internal cleaning or maintenance is required, the top cover can be opened. When the top is closed, a feeding port can also be provided on the top for feeding materials into the silo.

[0018] The feeding port is provided with or not provided with a feeding port cover for covering the feeding port.

[0019] An ash outlet 15 is provided at the bottom of the shell. The ash outlet 15 is located below the ash bin and is connected to the ash bin for discharging the ash in the ash bin.

[0020] The ash outlet is provided with an ash outlet cover for covering the ash outlet. The ash outlet cover can be in any suitable form such as a flip cover, a buckle cover or a sliding cover.

[0021] According to actual needs, the ash outlet can also be arranged at the lower part of the side wall of the ash bin.

[0022] The combustion chamber driving device can adopt a steering gear / DC servo motor.

[0023] A cigarette holder (or cigarette rod) 39 is installed / set at an appropriate position of the housing so that the inner end (inner port, located in the housing) of the cigarette holder is aligned with and fits the side wall of the combustion chamber at the smoking position, and one or more vents are set on the side wall of the combustion chamber opposite to the inner end of the cigarette holder, and these vents can be located at the lower part of the side wall. When the user inhales, the gas entering from the upper port of the combustion chamber passes through the tobacco in the combustion chamber, providing oxygen required for the tobacco combustion, and flows out from the vents together with the aerosol generated by the combustion, and is inhaled into the body through the cigarette holder.

[0024] The cigarette holder can be a retractable cigarette holder, for example, a retractable cigarette rod composed of several short tubes plugged together and capable of being pulled out.

[0025] The combustion chamber driving device (servo) is eccentrically arranged, and the axis of its output shaft does not overlap with the axis of the shell (they are parallel to each other and there is a certain distance between them), and is located on the ash bin side.

[0026] A transverse (horizontal) partition 14 is provided in the shell, and the transverse partition 14 is located below (at least including) the lower port of the combustion chamber from the feeding station to the smoking station (including the smoking station), and its upper surface is in contact with the lower port of the combustion chamber or leaves a small moving fit gap (a fit gap that allows the combustion chamber to swing), thereby preventing the material in the combustion chamber from coming out of the lower port of the combustion chamber when the combustion chamber swings from the feeding station to the smoking station and when the combustion chamber is on the smoking station.

[0027] In practice, the partition can be appropriately larger than the area where the lower port of the combustion chamber passes from the feeding station to the smoking station (including the smoking station) in the combustion chamber.

[0028] The upper surface of the partition is aligned with the top (discharge port) of the feed mechanism (in the same plane). When the coverage of the partition includes the area where the discharge port of the feed mechanism is located, a hole corresponding to the top of the feed mechanism can be set at the corresponding position of the partition, and the top of the feed mechanism can be embedded (fixedly installed) on the hole.

[0029] The feeding mechanism adopts a spiral (auger) feeding mechanism, which is arranged vertically. The feeding port of the feeding mechanism is located at the bottom of the silo, and the discharging port is adjacent to and aligned with the lower port of the combustion chamber at the feeding station (aligned up and down). That is, the feeding station of the combustion chamber is a position where its lower port is adjacent to and aligned up and down with the discharging port of the feeding mechanism, so that the material delivered from the upper port of the feeding mechanism enters the combustion chamber from the lower port of the combustion chamber.

[0030] The feeding mechanism includes a vertically arranged screw rod 20 and a sleeve 24 coaxially sleeved on the outside of the screw rod. The screw rod is provided with a spiral blade or thread 21 for conveying materials, and the lower end of the screw rod is provided with a feeding drive device 25 for driving the screw rod to rotate.

[0031] The lower end of the sleeve constitutes the feed inlet of the feed mechanism, and the upper end of the sleeve constitutes the discharge port of the feed mechanism. The top of the screw is not higher than the top of the sleeve, and can usually be located on the same horizontal plane or slightly lower than the top of the sleeve to avoid hindering the swing of the combustion chamber. The lower part of the screw extends from the lower end of the sleeve and is drivingly connected to the output shaft of the feed drive device (for example, coaxially connected through a coupling).

[0032] The feed drive device may be a stepper motor so as to accurately control the number of rotations (angle) of the screw rod.

[0033] The feed drive device may or may not be provided with a cover plate 26. The cover plate prevents the material put into the silo from falling around the drive device, which helps to avoid the material deposited around the drive device affecting the heat dissipation and also helps to avoid the material being deposited around the drive device for a long time.

[0034] The ash falling mechanism is provided with a push rod extending downward, and the front end (or end) of the push rod is provided with or without a push plate 44, and the push plate is conformable to the inner cavity of the combustion chamber, and its cross-section is slightly smaller than the cross-section of the combustion chamber. The ash falling mechanism is located above the combustion chamber at the feeding station, and its push rod is coaxial with the combustion chamber at the feeding station (the axis is on the same straight line), or in other words, the ash falling station of the combustion chamber is located below the ash falling mechanism and the combustion chamber at the ash falling station is coaxial with the push rod of the ash falling mechanism.

[0035] The vertical partition is provided with a notch 17 that allows (does not hinder) the swing of the combustion chamber to avoid hindering the swing of the combustion chamber. The size and position of the notch are set according to actual needs.

[0036] The ash dropping mechanism adopts a magnetic (electromagnetic) push rod device. After power is turned on, the push rod moves downward, so that the push rod / push plate enters from the upper port of the combustion chamber at the ash dropping position, and pushes the ash in the combustion chamber from the lower port of the combustion chamber and falls into the ash bin.

[0037] The igniter may adopt any suitable existing technology, for example, an ignition device / ignition module of an existing electronic cigarette or an automatic ignition pipe. The specific setting position and posture (orientation) of the igniter may be determined according to the ignition requirements of the combustion chamber of the smoking station.

[0038] Typically, the ignition module may be an ignition module that uses the following two ignition mechanisms: one is arc ignition, and the other is laser ignition.

[0039] This bucket-type electronic cigarette can also be provided with a control device according to the prior art, which is used to control the operation of the combustion chamber drive device, the feed mechanism drive device, the ash falling mechanism drive device and the igniter.

[0040] The control method of the control device can be: 1) After obtaining a start signal (for example, after the user presses a start button), the combustion chamber driving device is controlled to swing the combustion chamber to the feeding position. If the combustion chamber is already at the feeding position, the next step (step 2) is directly implemented; 2) When the combustion chamber is in the feeding position, the driving device of the feeding mechanism drives the feeding mechanism to feed according to the set feeding amount (number of screw rotations); 3) Control the combustion chamber drive device to swing the combustion chamber to the smoking position; 4) When the combustion chamber is in the smoking position, the igniter is controlled to ignite; or, when the combustion chamber is in the smoking position and a puffing signal is obtained, the igniter is controlled to ignite; or, when the combustion chamber reaches the smoking position and a set delay has elapsed, the igniter is controlled to ignite; 5) After receiving the ash dropping signal (for example, after the user presses the ash dropping button), the combustion chamber driving device is controlled to swing the combustion chamber to the ash dropping position. After the combustion chamber reaches the ash dropping position, the driving device of the ash dropping mechanism is controlled to perform the ash dropping action (the push rod moves downward). The ash dropping action can be performed only once (especially when a push plate is provided), or it can be repeated multiple times according to a set number of times (especially when no push plate is provided); 6) After the ash dropping action is completed (one or more times according to the set method), the combustion chamber driving device is controlled or not controlled to swing the combustion chamber to the set starting position (for example, the feeding position or the smoking position).

[0041] According to the existing technology, a suitable chip / microprocessor (and associated components / circuits) can be provided as a control device, and the above control can be implemented with the support of a preset program / pre-installed software.

[0042] Sensors required for control can be set according to the existing technology to obtain signals required for control. For example, the output angle signal of the servo (combustion chamber drive device) can be obtained through the (output shaft) angle signal output of the servo (combustion chamber drive device) itself or a separately set servo output shaft angle signal sensor to determine / determine the swing angle of the combustion chamber and the position of the combustion chamber; a temperature sensor for detecting the temperature in the combustion chamber is set to obtain temperature data in the combustion chamber to determine whether ignition is successful or whether smoking has been completed; a pressure sensor or airflow velocity sensor is set to detect the gas pressure or flow velocity in the cigarette holder or the combustion chamber, and judge whether the user is performing a smoking action (inhalation) based on the obtained pressure signal or airflow signal.

[0043] A battery compartment and batteries / battery packs used as power sources for various power-consuming parts can be provided according to the prior art.

[0044] The electrical connection and signal transmission lines can be set according to actual needs.

[0045] The basic working process of this type of cigarette butt is as follows: the feed drive motor drives the screw rod to bring the tobacco material at the bottom of the silo into the sleeve and directly to the combustion chamber at the top of the sleeve; when the smoking station and the feeding station are no longer together, the servo drives the combustion chamber to the smoking station (if the smoking station and the feeding station are the same station, this step / action is omitted); the igniter ignites, and inhales / smokes through the telescopic tube used as a cigarette rod; after smoking is completed, the servo drives the combustion chamber to rotate to the ash bin, and the ash in the combustion chamber is pushed out by the electromagnetic push rod, completing a cycle.

[0046] Unless otherwise specified or when one preferred or optional technical means is a further limitation of another technical means, the preferred and optional technical means disclosed in the present invention can be arbitrarily combined to form several different specific implementation methods.
