BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the structure of the present invention; Figure 2 is with Figure 1 The corresponding perspective view. DETAILED DESCRIPTION

[0017] See also Figure 1 and Figure 2 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 chamber 21 and a lower chamber 22. The upper chamber is a silo, and a feeding port 26 is arranged on the top of the silo so that the tobacco material can be fed into the silo through the feeding port. The lower part of the silo adopts an impeller feeding mechanism (impeller feeder, or rotary feeder), and is provided with a rigid impeller (or gear) 30 for feeding. According to the feeding / unloading purpose of the impeller feeding structure in the pipe, the rigid impeller can be called a feeding wheel. The partition structure (for example, a partition) between the upper chamber and the lower chamber can be regarded as a part of the shell, or the shell is 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. A feeding channel 25 is arranged in the middle of the partition structure to achieve the connection between the upper chamber and the lower chamber and the transportation of tobacco material.

[0018] The feeding port is used to connect the silo and is a passage for feeding tobacco and other tobacco materials into the silo. Under normal circumstances, the top of the shell can be open, and a top cover 12 can be provided to cover the top opening; or a top open structure can be adopted without a top cover, so as to directly observe the internal conditions of the shell. 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. The top of the shell is open, and a top cover 12 can be provided to cover the top opening, or a top open structure can be adopted without a top cover, so as to directly observe the internal conditions of the shell, which is convenient for feeding and cleaning. If necessary, a fixed top plate is also provided on the top of the shell. In the case of an open top, the top opening of the shell is used as / constituted as 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 feed hopper can be provided on the top of the side wall. Specifically, it can be flexibly set into any suitable form according to actual conditions, and the side of the shell can also be set as a detachable structure if necessary.

[0019] 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.

[0020] According to actual needs, the feeding port may or may not be provided with a feeding port cover to cover it.

[0021] The bottom of the housing may be provided with an ash outlet 28. The ash outlet is located at the bottom of the lower chamber of the housing, communicates with the lower chamber, and can be used to discharge the ash (or soot) in the lower chamber.

[0022] 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.

[0023] 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.

[0024] An inclined plate 13 for forming a conical (truncated cone) space that is larger at the top and smaller at the bottom may be provided at the lower portion of the lower chamber to facilitate dust cleaning.

[0025] The impeller and the hopper shell around the impeller can be set according to the impeller feeding mechanism and the requirements for tobacco output. The blades (impeller blades, or teeth) 33 on the feeding wheel are straight blades, and long teeth with a certain height are used. The V-shaped space (V-shaped cell, or V-shaped groove) 32 between adjacent blades can be called a feeding chamber, which can accommodate tobacco. When the feeding wheel rotates, the tobacco in the feeding chamber is kept in the feeding chamber under the constraints of surrounding structures such as the surrounding shell, and moves with the feeding wheel until the feeding chamber rotates to the drop station (the position opposite to the feeding channel). Since there is no physical structure constraint (blocking) below the feeding chamber, the tobacco falls under the action of its own gravity, passes through the feeding channel, and enters the combustion chamber located below the feeding channel and aligned with the feeding channel.

[0026] The feed wheel can be rotatably mounted in the upper cavity shell by appropriate means such as bearings. For example, the two side shaft extensions of the feed wheel are mounted on the inner side of the upper cavity shell through bearings and bearing seats, and the rotation axis of the feed wheel is horizontal (the horizontal direction where the rotation axis is located is horizontal).

[0027] The smoke material dropped from the feeding port or the smoke material located above the feeding wheel can directly fall into the upward (including obliquely upward) feeding chamber, and as the feeding wheel rotates, the smoke material around the feeding wheel can also enter the feeding chamber until the feeding chamber is filled (when there is enough smoke material in the silo). When any feeding chamber containing smoke material is turned to face downward toward the feeding channel, the smoke material in the feeding chamber falls and enters the combustion chamber below the feeding channel through the feeding channel.

[0028] As the feeding wheel rotates, the feeding chambers filled with smoke material arrive above the feeding channel in turn, so that the smoke material in each feeding chamber falls into the combustion chamber below the feeding channel in turn, and the emptied feeding chamber is refilled with smoke material before the next rotation to the dropping station (the position facing downwards to the feeding channel).

[0029] The combustion chamber (or burner) 40 adopts a wheel-type combustion chamber, which is in the shape of an annular column (a column with a circular cross-section) of equal diameter. A number of radial through holes 42 used as combustion chambers are evenly spaced on the side wall of the annular column. The radial through holes are in the same axial position on the annular column (usually the axial middle of the annular column), or in other words, they are distributed on the same circumference. When the empty combustion chamber is turned to a vertical upward position / posture, it faces the feed channel and can receive the smoke delivered by the feed wheel through the feed channel. The port of the combustion chamber can be made slightly larger than the feed channel and close to the lower port of the feed channel (basically close but not hindering the rotation of the combustion chamber) to ensure that all the smoke falling from the feed channel can enter the combustion chamber.

[0030] The lower chamber is used as the working chamber and ash chamber of the combustion chamber. The combustion chamber is arranged at the upper part of the lower chamber. As a preferred embodiment, the central axis of the feeding chamber at the blanking station, the central axis of the feeding channel and the central axis of the combustion chamber at the charging station overlap each other (are located on the same vertical straight line) longitudinally, that is, the vertically downward feeding chamber is located directly above the feeding channel, and the vertically upward combustion chamber is located directly below the feeding channel, so as to facilitate the smoke material to fall from the feeding chamber and enter the combustion chamber. Therefore, the rotation axis of the combustion chamber should be located directly below the rotation axis of the feeding wheel, the feeding channel should be vertically aligned with the axis of the feeding wheel and the combustion chamber, and the feeding channel should be located in the middle of the partition structure between the upper chamber and the lower chamber.

[0031] The combustion chamber can be rotatably mounted in the lower chamber housing by suitable means such as bearings. For example, the shafts on both sides of the combustion chamber are mounted on a bearing seat fixed to the inner side of the lower chamber housing through bearings, and the rotation axis is horizontal and parallel to the rotation axis of the feed wheel.

[0032] As the combustion chamber rotates, the emptied (ash-falling / ash-cleaned) combustion chambers arrive at the bottom of the feed channel one by one, and are loaded with smoke materials in turn in coordination with the action (rotation) of the feed wheel. The feed wheel and the combustion chamber can work together to load smoke materials into the combustion chambers passing under the feed channel.

[0033] Under normal circumstances, one combustion chamber is loaded with the smoke material of one feeding chamber, that is, one feeding chamber is used to load one combustion chamber. If necessary, one combustion chamber can also be loaded with the smoke material of multiple feeding chambers, that is, multiple feeding chambers are used to load one combustion chamber. In this case, after the empty combustion chamber reaches the bottom of the feeding channel, the smoke material of multiple feeding chambers is loaded into the combustion chamber through the rotation of the feeding wheel. After the loading of the combustion chamber at the loading station is completed, the combustion chamber will implement the next rotation to move the next empty combustion chamber to the bottom of the feeding channel.

[0034] The number of the feed chambers (equal to the number of blades / teeth on the feed wheel) can be the same as the number of combustion chambers on the combustion chamber, preferably 6, or 8 or other suitable numbers. In the case where only one feed chamber is used to charge a combustion chamber, the feed wheel and the combustion chamber can be synchronously intermittently rotated, each rotation angle is 60° (when the number of feed chambers and combustion chambers are both 6) or other suitable angles. In coordination with the action and initial position of the feed wheel and the combustion chamber, a feed chamber on the feed wheel rotates to a vertically downward position (this position can be called a drop position), and a combustion chamber of the combustion chamber rotates to a vertically upward position (this position can be called a loading position). At the same time, the combustion chamber previously located at the loading position is rotated to a position where it can be ignited by the igniter (this position can be called a smoking position, or an ignition position), and the combustion chamber on the same diameter as the vertically upward combustion chamber position is in a vertically downward position (this position can be called an ash dropping position). In the above state, the feeding chamber facing vertically downward can be dropped, the combustion chamber facing vertically upward can be loaded, and the combustion chamber facing vertically downward can be ash dropped / cleaned. At the same time, the igniter 50 can ignite the combustion chamber located at the ignition position according to the user's operation (for example, pressing the ignition button, or inhaling through the cigarette holder) or according to a set program, so that the user can smoke. The size of the feeding chamber and the combustion chamber can be set according to actual needs.

[0035] From the perspective of a single combustion chamber, or in other words, for any combustion chamber, as the combustion chamber rotates, the combustion chamber passes through the loading station, the smoking station and the ash dropping station (or ash cleaning station) in sequence, and then returns to the loading station again to start the next cycle. The smoking station is preferably the location of the adjacent combustion chamber in the forward direction (in front of the forward rotation of the combustion chamber) with the vertically upward combustion chamber, and can also be any station from the loading station (forward rotation) to the ash dropping station. According to the setting or requirements of the smoking station, an igniter can be appropriately set so that it can ignite the combustion chamber located at the smoking station.

[0036] The position of the vertically upward combustion chamber is the loading station, and the smoke material falling into the lower chamber from the feeding channel enters the combustion chamber at the loading station; the position of the vertically downward combustion chamber is the ash falling station, and the smoke ash (ashes) in the combustion chamber at the ash falling station falls from the combustion chamber by its own gravity. When an ash falling push rod device is provided, the push rod of the ash falling push rod device moves downward to push the smoke ash in the combustion chamber out of the combustion chamber, further ensuring the ash cleaning effect.

[0037] When the number of combustion chambers is an even number (for example, 6), any combustion chamber has another combustion chamber located on the same diameter. When one combustion chamber is in the loading position, there must be another combustion chamber in the ash dropping position. In addition, through the reasonable setting of the igniter, one combustion chamber can also be in the smoking position. The smoking position is preferably the adjacent position of the loading position in the forward direction (forward, or front).

[0038] The feed wheel motor (not shown) for driving the feed wheel to rotate is located on one lateral side of the feed wheel and is fixedly mounted on the outer side of the upper chamber shell. It can also be fixedly mounted on the inner side of the upper chamber 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 combustion chamber motor. Under normal circumstances, the output shaft of the feed wheel motor can be coaxial with the rotating shaft (shaft extension) of the feed wheel (the axes of the two are located on the same straight line) and connected through a coaxial coupling, or it can be connected by a gear transmission mechanism, thereby realizing the driving connection of the feed wheel motor to the feed wheel.

[0039] The feed wheel motor is preferably a stepper motor.

[0040] The combustion chamber motor (not shown) for driving the combustion chamber to rotate is located on one lateral side of the combustion chamber and is fixedly mounted on the outer side of the lower chamber shell. It can also be fixedly mounted on the inner side of the lower chamber 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 combustion chamber motor. Under normal circumstances, the output shaft of the combustion chamber motor can be coaxial with the rotating shaft (shaft extension) of the combustion chamber and connected through a coaxial coupling, or it can be connected by a gear transmission mechanism, thereby realizing the driving connection of the combustion chamber motor to the combustion chamber.

[0041] The combustion chamber motor is preferably a stepper motor.

[0042] The combustion chamber motor and the feed wheel motor can be provided separately or can be the same motor. When the combustion chamber motor and the feed wheel motor use the same motor, the motor is respectively connected to the combustion chamber (the rotating shaft of the combustion chamber) and the feed wheel (the rotating shaft of the feed wheel) through two (two-way) synchronous output shafts of the synchronous transmission mechanism, thereby realizing synchronous driving of the combustion chamber and the feed wheel.

[0043] The motor used to synchronously drive the combustion chamber and the feed wheel can also be a stepper motor.

[0044] As a preferred embodiment, the motor (combustion chamber motor and feed wheel motor, or a single motor that synchronously drives the combustion chamber and the feed wheel) can be fixedly mounted on the outside of the housing. A motor cover can be provided to cover the outside of the motor, and the motor cover can be provided with a plurality of heat dissipation vents to facilitate heat dissipation. Correspondingly, a housing vent (one or more) 24 can also be provided on the lower chamber housing facing or adjacent to the smoking station, and no special vent is provided on other parts of the lower chamber housing, so that the external air can smoothly enter the combustion chamber on the smoking station after entering the inner side of the housing through the vent on the lower chamber housing, and it is difficult to enter the combustion chamber at other positions.

[0045] The shells (upper chamber shells) located on the lateral sides of the feeding wheel are in the shape of parallel planes and close to the end faces of the feeding wheel, so as to prevent / avoid the smoke from falling into the bottom of the lower chamber through the gap between the feeding wheel and the shells on the lateral sides, and to prevent / avoid excessive airflow from entering the lower chamber through the gap between the feeding wheel and the shells on the lateral sides; at least part of the area of ​​the shell (which is or is mainly the partition structure between the upper and lower chambers) located below the circumferential surface of the feeding wheel (the circumferential surface / cylindrical surface where the tooth ends are located) is close to the circumferential surface of the feeding wheel (the rotating circumferential surface of the outer end of the impeller blade), so as to prevent / avoid the smoke from falling into the bottom of the lower chamber / feeding channel through the gap between the circumferential surface of the feeding wheel and the shell below the circumferential surface.

[0046] The shell below the circumference of the feed wheel may adopt a curved surface (cylindrical surface) structure similar to the circumference of the feed wheel at the corresponding position, or adopt inclined surfaces close to the two sides (longitudinal sides, the so-called longitudinal direction is the horizontal direction perpendicular to the transverse direction) below the circumference of the feed wheel. The gap between the shell at the corresponding position and the circumference of the feed wheel should not hinder the rotation of the feed wheel and should not be easily stuck by tobacco or the like.

[0047] The shells on both sides of the combustion chamber are parallel to each other and close to the two end faces of the combustion chamber, so as to prevent smoke or excessive airflow from passing through these gaps. The top of the combustion chamber is preferably close to the lower end of the material drop channel, so as to prevent or reduce air from entering the lower cavity from the upper cavity, and to ensure that the smoke falling from the material drop channel enters the combustion cavity below the material drop channel.

[0048] The lower cavity may be provided with an air baffle plate 17 surrounding the outer side of the combustion chamber. The air baffle plate may be cylindrical and close to the circumference of the combustion chamber, and is provided with discontinuous areas corresponding to the combustion chamber of the charging station and the combustion chamber of the ash dropping station, respectively, so as to avoid hindering the smoke material from entering the combustion chamber of the charging station or hindering the smoke ash from being discharged from the combustion chamber of the ash dropping station.

[0049] The air baffle plate is provided with air holes 27 or discontinuous areas at the position corresponding to the smoking station to avoid blocking or hindering air from entering the combustion chamber of the smoking station. At the same time, due to the isolation of the air baffle plate, there is basically no airflow into the tobacco cavity of other stations.

[0050] The central hole of the combustion chamber (the central through hole of the annular column structure) is provided with a suction head 16 that is rotatably matched with it (connected in a matching / connecting manner that allows both to rotate). The suction head is fixedly installed in the shell and is in the shape of an annular column that is coaxial with the combustion chamber (the axis is on the same straight line), one end of which (the end in the horizontal direction) is connected to the inner end of the cigarette rod (or cigarette holder) 15, and the port at the other end (the port of the central hole) is closed. The side wall (the side wall of the annular column) of the suction head facing the smoking station (the smoking station of the combustion chamber) is provided with a ventilation hole (one or more) 29 for the suction head, and no special ventilation holes are provided on the side walls of other parts. Since the ventilation holes on the suction head are only opposite to the combustion chamber in the smoking station, the air outside the combustion chamber can basically only enter the suction head and the cigarette rod through the combustion chamber on the smoking station, which helps to avoid excessive mixing of air that has not passed through the combustion chamber on the smoking station during smoking.

[0051] The connection between the side port of the suction head and the inner end of the cigarette rod can be a fixed sealing connection or a rotating sealing connection to allow the cigarette rod to be rotated / adjusted in angle. The rotating sealing connection is preferably a rotating sealing connection with damping, which relies on the damping to keep the cigarette rod at a set angle / posture.

[0052] The inner end of the cigarette rod faces the connection end of the cigarette rod on the suction head, and a 90° bending structure can be provided on the cigarette rod to make the inner end of the cigarette rod face the suction head.

[0053] An electromagnetic push rod (electromagnetic push rod device) is provided in the suction head. The push rod of the electromagnetic push rod device extends vertically downward. A push rod hole for passing the push rod is provided on the bottom of the suction head (the lower side wall of the circular column). 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 (is located in the push rod hole). When cleaning (ash dropping), the electromagnetic push rod is energized to move the push rod downward, inserted into the combustion chamber located at the ash dropping station below it, and the ashes in the combustion chamber are pushed downward to cause the ashes to fall.

[0054] The igniter 50 is used to ignite the combustion chamber that is rotated to / located on the smoking station, and ignites the tobacco material in the combustion chamber. The igniter can be installed in the lower chamber, located at the smoking station side of the combustion chamber.

[0055] 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.

[0056] 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.

[0057] According to the prior art, a control device for controlling the operation of each electric part (including a feed wheel motor and a combustion chamber motor, and also an electromagnetic push rod device when an electromagnetic push rod device is provided) can be provided.

[0058] The control method of the control device includes any one or more of the following: 1) According to the start signal (for example, the signal generated by pressing the start button), the feed wheel is controlled to rotate a certain angle (which can be the angle between the center lines of adjacent feed chambers) so that the feed chamber adjacent to the blanking station that was behind the blanking station (behind the feeding wheel rotation direction) before this rotation turns to the feeding station, that is, a vertically downward position; the combustion chamber is controlled to rotate a certain angle (which can be the angle between the center lines of adjacent combustion chambers) so that the combustion chamber adjacent to the loading station that was behind the loading station (behind the combustion chamber rotation direction) before this rotation turns to the loading station, that is, a vertically downward position. In this case, the combustion chamber that was at the loading station before this rotation turns to the smoking station, and the combustion chamber adjacent to the ash dropping station that was behind the ash dropping station before this rotation turns to the ash dropping station.

[0059] The rotation of the feed wheel and the combustion chamber can be implemented synchronously, or the combustion chamber can be controlled to rotate to a certain position (rotate to a set angle / angular distance) first, and then the feed wheel can be controlled to rotate to a certain position (rotate to a set angle / angular distance).

[0060] The way to control the rotation of the feed wheel is to turn on the power of the feed wheel motor so that the feed wheel motor works according to the rotation angle required by the feed wheel.

[0061] The method of controlling the rotation of the combustion chamber is to connect the power supply of the combustion chamber motor so that the combustion chamber motor works according to the rotation angle required by the combustion chamber.

[0062] When an electromagnetic push rod is provided, after the combustion chamber is rotated, the electromagnetic push rod device is controlled to perform a push rod pushing action, and the push rod pushing action can be performed once or multiple times according to a set number.

[0063] 2) According to the smoking signal or the set program, the igniter is controlled to ignite. The igniter can only be controlled to ignite after the feed wheel and the combustion chamber are both rotated to the right position and a certain delay has passed. If the smoking signal is received before the feed wheel and the combustion chamber are both rotated to the right position and a certain delay has passed, the igniter is controlled to ignite after the feed wheel and the combustion chamber are both rotated to the right position and a certain delay has passed.

[0064] 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) and after the delay time has elapsed, controlling the igniter to ignite; ii) After the feed wheel and the combustion chamber have rotated to their proper positions and after a certain delay, the igniter is controlled to ignite; iii) After the inhalation signal is sensed and the delay time is reached, the igniter is controlled to ignite. An airflow sensor or pressure (air pressure) sensor that can sense the airflow or air pressure (dynamic pressure or static pressure) signal in the cigarette rod or the suction head can be set, 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).

[0065] 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.

[0066] Sensors required for control can be set according to the existing technology to obtain the signals required for control. For example, a rotary encoder for the feed wheel and a rotary encoder for the combustion chamber are set to obtain the rotation angles of the feed wheel and the combustion chamber respectively, and determine whether the feed wheel and the combustion chamber are rotated in place; a temperature sensor for detecting the temperature in the combustion chamber is set to obtain the temperature data in the combustion chamber to determine whether the ignition is successful or whether the smoking is finished; a pressure sensor or an airflow velocity sensor is set to detect the gas pressure or airflow velocity in the cigarette rod, or in the suction head, or in the combustion chamber, and determine whether the user is performing the smoking action (inhalation) based on the pressure signal or airflow velocity signal obtained.
