[0011] Preferably, the pipe-shaped electronic cigarette is also provided with a control device for controlling the operation of each electric part.

[0012] Preferably, the control method of the control device includes: 1) Combustion chamber position conversion control: According to the start signal, the burner is controlled to rotate a certain angle (for example, when there are four combustion chambers, rotate 90°), so that the combustion chamber that was in the loading position before this rotation is transferred to the ignition position, and correspondingly, the combustion chamber that was in the ignition position before this rotation is transferred to the ash removal position, and the combustion chamber that was behind the loading position and adjacent to the loading position before this rotation is transferred to the loading position.

[0014] The beneficial effects of the present invention are as follows: since a plurality of cup-shaped combustion chambers are arranged on the burner, the switching and rotation of the combustion chambers at different positions can be realized by rotating the burner, and in the same posture of the burner (the same burner position), one combustion chamber is in the loading position, one combustion chamber is in the ash cleaning position, and one combustion chamber is in the ignition position (smoking position), thereby simplifying the structure and action process of the automatic tobacco pipe; since an ash pushing device is arranged at the cup bottom of the burner, and a push rod device matching the ash pushing device is provided, the consolidation of the ash in the combustion chamber can be destroyed by pushing the push plate in the combustion chamber, thereby ensuring the ash cleaning effect; since an ignition module is arranged, no manual ignition is required; since the burner The relative position between the lever and the drop channel is used to open and close the drop channel, which not only simplifies the operation process, but also can control the opening time of the drop channel by controlling the rotation speed of the burner (and, when necessary, the short pause time when the drop channel is open, etc.), thereby controlling / adjusting the charging amount of the combustion chamber; since the corresponding parts of the burner and the inner wall of the lower cavity (the adjacent parts during the rotation process) are matched with a sliding gap, the gap between the two is reduced as much as possible while allowing relative sliding (relative rotation), which not only avoids the passage of tobacco through the gap between the two, but also greatly ensures that the gas inhaled by the user basically passes through the combustion chamber in the smoking position, thereby ensuring the smoking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION

[0016] See also Figure 1 This electronic cigarette is a pipe that uses tobacco or tobacco mixture (tobacco mixed with auxiliary materials). The cavity in the shell 10 is divided into an upper cavity and a lower cavity 23. The upper cavity is further divided into a material bin 21 and a device bin 22 by an upper cavity partition. The device bin is in front and the material bin is in the back. The material bin is located above the rear of the lower cavity. The bottom surface of the material bin adopts an inclined curved surface or an inclined plane inclined in the direction of the material drop channel. The tobacco can slide down / fall down by its own gravity. Therefore, when the material drop channel is opened, the tobacco will automatically fall from the material bin through the material drop channel into the rear of the lower cavity.

[0017] The material drop channel is arranged in the lower area of ​​the partition structure between the silo and the lower chamber, that is, the rear part of the partition structure, so as to facilitate the sliding of the smoke material and facilitate the smoke material that falls into the lower chamber to enter the combustion chamber at the rear part of the lower chamber. When the number of combustion chambers is 4, the loading station is a position where the combustion chamber cup mouth is horizontal and facing upward, and the combustion chamber moving toward the loading station can also be regarded as being in the loading station. The partition structure (for example, a partition) between the silo and the lower chamber can be regarded as a part of the shell, or in other words, the shell can be regarded as consisting of an upper chamber shell and a lower chamber shell, and the partition structure between the upper and lower chambers is a common part of the upper chamber shell and the lower chamber shell.

[0018] A cigarette rod 15 is provided at the rear side of the lower cavity, and the inner end of the cigarette rod is connected to the rear space of the combustion chamber at the ignition position (the rear space is located in the lower cavity).

[0019] The end of the cigarette rod may be provided with an enlarged diameter (area with enlarged pore size) 25 which can be embedded / inserted into the filter.

[0020] A feeding port 25 is provided on the top of the silo, which is connected to the upper cavity and is used as a passage for feeding tobacco materials such as shredded tobacco into the silo.

[0021] Under normal circumstances, the top of the silo is open, and may be provided with a top cover for covering the top opening, or may be provided without a top cover, and directly adopt a top open structure, so as to directly observe the internal conditions of the shell and feed into the silo. In addition, when appropriate, a fixed top plate is also provided on the top of the shell. In the case of an open top (no top cover), the top opening of the shell is used as / constitutes a feeding port; when a top cover is provided, the feeding port can be opened on the top cover; when the top of the shell is closed, a feeding port can be provided on the top plate of the shell or a feeding hopper can be provided on the top of the side wall. Specifically, it can be flexibly set into any appropriate form according to actual conditions.

[0022] The top cover can be any suitable form such as flip cover, buckle cover and slide cover. When the interior needs to be cleaned or repaired, the top cover can be opened.

[0023] According to actual needs, the feeding port may or may not be provided with a feeding port cover to cover it.

[0024] The bottom of the housing may be provided with an ash outlet 27. The ash outlet is located at the bottom of the lower chamber of the housing, connected to the lower chamber, and can be used to discharge the ash (or soot) in the lower chamber.

[0025] 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.

[0026] According to actual needs, a door opening and a door (not shown) matching the door opening can be provided at the lower part of the side wall of the lower chamber. The door can be called an ash cleaning door. The door opening can be regarded as an implementation of an ash outlet for removing the ash in the lower chamber. When the ash cleaning door is provided, the aforementioned ash outlet can be provided at the same time or not.

[0027] The shell (the shell forming the boundary of the lower cavity / the shell surrounding the outer side of the lower cavity) is provided with an air inlet 25 connected to the cup mouth of the combustion chamber located at the ignition station. The air inlet can be set on the shell between the ignition station and the cleaning station. For example, the lateral side plate of the shell in this area, and / or the peripheral plate of the shell in this area.

[0028] During the rotation of the burner, when the combustion chamber located at the rear of the lower chamber moving from the loading station to the ignition station reaches the cover plate lever 19 of the elastic cover plate 18, the outer edge of the combustion chamber pushes the lever forward. Since the elastic cover plate is hinged at the blanking channel (for example, on the walls on both sides of the blanking channel), a bearing seat for realizing the hinge (rotational connection) of the elastic cover plate can be provided on the upper surface (side surface of the silo) of the partition structure (or partition) between the silo and the lower chamber, so as to install the elastic push plate through the bearing. The shape and size of the blanking channel (and other auxiliary facilities / structures) should be adapted to the elastic cover plate and its swing (rotation) within a reasonable range, allowing the main part of the elastic cover plate to flip downward (inward). When the elastic cover plate covers the blanking channel hole, the blanking channel should be able to prevent the main part of the elastic cover plate from continuing to flip upward (for example, a slope or tongue-and-groove structure that can block the elastic cover plate is provided).

[0029] The smoke material falling from the blanking hole enters the area between the two combustion chambers, and then continues to fall / slide down into the rear combustion chamber of the two combustion chambers. The shape, size and position of the blanking hole / elastic cover plate should be reasonably set so that during each rotation of the burner, when the first (moving upward from a horizontal state) combustion chamber turns to a certain angle (posture), it contacts the cover plate lever and drives the elastic cover plate to rotate by pushing the cover plate lever, opening the blanking hole. Before the combustion chamber moves to the cigarette lighting position, the cover plate detaches from the rear side of the combustion chamber, so that the elastic cover plate returns to the normal state of covering the blanking hole (the initial state of this action) under the action of its reset spring.

[0030] The burner (or burner) adopts a windmill type burner 30, which can arrange four combustion chambers 33 at equal angular distances, and the central gathering part or the parts where any two combustion chambers fit each other are connected to form an integral burner. The central axis of each combustion chamber connected to each other constitutes the axis of the connected rear burner. During the rotation process, the stroke of the outer end of each combustion chamber forms a cylindrical surface, which can be called the outer peripheral surface of the burner, and the outer circle shape and size of the lower cavity are adapted to (may be slightly larger than) the outer peripheral surface, so that the burner can rotate in the lower cavity and minimize the gap between the two.

[0031] The combustion chamber (cup-shaped combustion chamber) is cup-shaped with one side open, and the cup mouth is located at the front side in the circumferential direction (the shape of the cup mouth can usually be rectangular). This cup shape can also be called a groove shape, and the cup mouth is called a groove mouth.

[0032] The two lateral sides of the combustion chamber are flat plates, and the radial outer side is preferably a cylindrical panel. The axis of the cylindrical panel (corresponding to the axis of the cylinder) overlaps with the rotation axis of the burner. The opposite side of the cup mouth is the cup bottom, and the cup bottom is a flat plate parallel to the plane where the cup mouth is located. The radial inner plate can be flexibly set to block the corresponding sides of the flat plates on the two lateral sides, thereby forming a groove-shaped combustion chamber.

[0033] The vent hole 36 at the rear of the combustion chamber may be provided on the bottom of the cup.

[0034] The burner can be rotatably mounted in the lower cavity housing by suitable means such as bearings. For example, the shafts on both sides of the burner are mounted on a bearing seat fixed on the inner side of the lower cavity housing through bearings, and the rotation axis is horizontal.

[0035] The burner rotates intermittently, each rotation angle is 90° (when there are 4 combustion chambers) or other suitable angles. By controlling the rotation of the burner, the amount of charge in the combustion chamber can be controlled each time.

[0036] When four combustion chambers are set, at any position of the burner (the position it should be in the stopped rotation state), one combustion chamber of the burner rotates to a position where the cup mouth is vertical and upward (this position can be called the ignition position, or the smoking position). In this state, the igniter can be controlled to ignite and smoke. At the same time, the combustion chamber that was previously (before this rotation) in the ignition position rotates to a position where the cup mouth is horizontally facing downward (this position can be called the cleaning position). In this state, the push rod 42 of the electromagnetic push rod device 41 can be controlled to move outward (downward), pushing the force-bearing column 46 downward, and then moving the push plate 45 downward to push out the ash in the combustion chamber (if any, part or all of it has been allowed to fall during the process of the combustion chamber moving from the ignition position to the cleaning position). When there is solidified ash in the combustion chamber, this pushing action can destroy the solidification state, thereby causing the ash to fall under the action of its own gravity. After the push rod of the electromagnetic push rod device is retracted, the push plate returns to a position close to the bottom of the cup under the action of its return spring (which can be a small tension spring between the push plate and the bottom of the cup) 45. The size of the combustion chamber, the size of the blanking channel, and the rotation speed of the burner or the time of each rotation can be set according to actual needs.

[0037] From the perspective of a single combustion chamber, or in other words, for any combustion chamber, as the burner rotates, the combustion chamber passes through the loading station, the smoking station and the cleaning station in sequence, and then returns to the loading station to start the next cycle. When there are four combustion chambers, the smoking station is a position where the cup mouth is vertical (the plane where the cup mouth is located is vertical) and is at the top (the upper part of the burner), the cleaning station is a position where the cup mouth is horizontal and facing downward, the charging station is a position where the cup mouth is horizontal and located at the upper part of the burner, and there is another combustion chamber where the cup mouth is vertical and located at the lower part of the burner, which is between the cleaning station and the charging station.

[0038] The igniter 49 can be appropriately arranged according to the position and posture of the combustion chamber at the smoking station (eg, the orientation of the cup mouth) so as to ignite the combustion chamber at the smoking station.

[0039] The burner motor (not shown) used to drive the burner to rotate is located on one lateral side of the burner and is fixedly mounted on the outer side of the lower cavity shell. It can also be fixedly mounted on the inner side of the lower cavity shell according to actual needs. When installed on the inner side of the shell, the shell at the corresponding part can be set to a convex structure that can accommodate the burner motor. Under normal circumstances, the output shaft of the burner motor can be coaxial with the rotating shaft (shaft extension) of the burner and connected through a coaxial coupling, or it can be connected by a gear transmission mechanism, thereby realizing the drive connection between the burner motor and the burner.

[0040] The burner motor is preferably a stepper motor.

[0041] When the burner motor is fixedly mounted on the outside of the shell, a motor cover covering the outside of the motor can be provided, and the motor cover can be provided with a plurality of heat dissipation vents to facilitate heat dissipation.

[0042] The lower cavity is adapted to (or conforms to) the shape of the burner, and is in the shape of a cylinder with a transverse axis, and the axis of the lower cavity (the axis of the cylindrical shape of the lower cavity) overlaps with the rotation axis of the burner, and the inner surface of the lower cavity (including the transverse inner wall and the peripheral inner wall) is matched with the transverse outer side surface and radial outer side surface of the combustion chamber in a sliding clearance (a small gap is left between the two to allow sliding).

[0043] For example, the lower cavity shells located on both sides of the burner can be parallel to each other and close to the two end faces of the burner, so as to prevent / avoid smoke or excessive airflow from passing through these gaps; the lower cavity shell located outside the circumference of the burner can be cylindrical and surround the outside of the burner. The inner surface of the shell should be close to the surface of the burner, so as to prevent or reduce the air from passing through the gap between the two, and to ensure that smoke cannot pass through the gap between the two.

[0044] A push rod hole that goes through from top to bottom should be set on the partition structure between the device bin and the lower chamber to allow the push rod to pass through. The normal position of the push rod is preferably inserted into the push rod hole and its lower end does not extend from the push rod hole (located inside the push rod hole). When cleaning (dust falling), the electromagnetic push rod is energized to move the push rod downward, contact the force-bearing column end to end, and push the force-bearing column downward.

[0045] The igniter 50 in the device compartment is used to ignite the combustion chamber rotated to / located on the smoking station to ignite the tobacco in the combustion chamber. The ignition can be carried out by connecting the ignition electrode arranged at the ignition position of the lower chamber through a wire.

[0046] 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.

[0047] 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.

[0048] According to the prior art, a control device for controlling the operation of each electric part (including a feed wheel motor and a burner motor, and also an electromagnetic push rod device when an electromagnetic push rod device is provided) can be provided.

[0049] The control method of the control device includes any one or more of the following: 1) Combustion chamber position conversion: Based on the start signal (for example, the signal generated by pressing the start button), the burner is controlled to rotate a certain angle (for example, when there are four combustion chambers, rotate 90°), so that the combustion chamber that was in the loading position before this rotation is turned to the ignition position. At the same time, the combustion chamber that was in the ignition position before this rotation is turned to the ash removal position, and the combustion chamber that was behind the loading position and adjacent to the loading position before this rotation is turned to the loading position.

[0050] The burner rotation can be controlled by turning on the power of the burner motor so that the burner motor works according to the rotation angle required by the burner.

[0051] When an electromagnetic push rod is provided, after the burner is rotated, the electromagnetic push rod device is controlled to perform the push rod pushing action. The push rod pushing action can be performed once or multiple times according to a set number. The number of push rod actions after the electromagnetic push rod device is powered on can be pre-set according to the prior art.

[0052] The electromagnetic push rod device can be controlled by switching on the power supply of the electromagnetic push rod device, so that the push rod device (electromagnetic drive device) works according to the displacement required by the push plate.

[0053] 2) According to the smoking signal or the set program, the igniter is controlled to ignite. The igniter can be controlled to ignite only after the burner is rotated to the right position. If the smoking signal is received before the burner is rotated to the right position, the smoking signal is ignored, or the igniter is controlled to ignite after the burner is rotated to the right position.

[0054] The method of controlling the ignition of the igniter according to the smoking signal or according to the set program is any of the following: i) after the user presses the smoking button (if a smoking button is provided) (for example, after obtaining a signal generated by pressing the smoking button), controlling the lighter to ignite; ii) After the burner is rotated into position, control the igniter to ignite; iii) After sensing the inhalation signal, the igniter is controlled to ignite. An airflow sensor or pressure (air pressure) sensor capable of sensing the airflow or air pressure (dynamic pressure or static pressure) signal in the cigarette rod or in the lower cavity in front of the smoking station can be provided, and the inhalation signal is obtained according to the change of the induction signal of the airflow sensor or pressure sensor in the inhalation state (relative to the change of the induction signal in the non-inhalation state).

[0055] 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.

[0056] Sensors required for control can be set according to existing technologies to obtain signals required for control. For example, a rotary encoder of the burner is set to obtain the rotation angle of the burner and determine whether the burner is rotated to the right position; a temperature sensor is set to detect the temperature in the combustion chamber to obtain temperature data in the combustion chamber to determine whether the ignition is successful or whether the smoking is finished; a pressure sensor or airflow velocity sensor is set to detect the gas pressure or airflow velocity in the cigarette rod or burner (at a suitable position) to determine whether the user is performing a smoking action (inhalation) based on the pressure signal or airflow velocity signal obtained.

[0057] A battery compartment and batteries / battery packs used as power sources for various power-consuming parts can be provided according to the prior art.

[0058] Lines for electrical connection and signal transmission can be set according to actual needs.

[0059] 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.
