The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only. The various objects in the drawings of the embodiments are drawn to scale for ease of illustration and not to scale for actual components.

The aerosol-generating substance according to the embodiments of the present invention refers to a smoking substance, which is a substance that can generate an odor and/or nicotine and/or smoke upon heating or burning, i.e. a smoke substance, which can be atomized. The smoke may be solid, semi-solid, and liquid. Solid tobacco materials are often processed into flakes due to air permeability, assembly, and manufacturing considerations, and are therefore also commonly referred to as flakes, and filamentary flakes are also referred to as flake filaments. The tobacco materials discussed in the embodiments of the present invention may be natural or synthetic tobacco liquids, oils, gums, pastes, cut filler, tobacco leaves, etc., e.g., synthetic tobacco materials containing glycerin, propylene glycol, nicotine, etc. The tobacco juice is liquid, the tobacco oil is oily, the tobacco gum is gel, the tobacco paste is paste, the tobacco shreds comprise natural or artificial or extracted tobacco shreds, and the tobacco leaves comprise natural or artificial or extracted tobacco leaves. The smoke may be heated in a form that is encapsulated by other substances, such as in a thermally degradable package, e.g. microcapsules, and the desired volatile substances are removed from the degraded or porous encapsulation package after heating.

The tobacco material provided by the embodiment of the invention can contain nicotine or does not contain nicotine. The tobacco material containing nicotine can comprise natural tobacco product, and at least one of tobacco juice, tobacco tar, tobacco gum, tobacco paste, tobacco shred, tobacco leaf, etc. prepared from nicotine. The tobacco liquid is water-like, the tobacco oil is oil-like, the tobacco gum is gel, the tobacco paste is paste, the tobacco shreds comprise natural or artificial or extracted tobacco shreds, and the tobacco leaves comprise natural or artificial or extracted tobacco leaves. The tobacco material without nicotine mainly contains fragrant substances, such as perfume, which can be atomized to simulate smoking process and stop smoking. In one embodiment, the flavor comprises peppermint oil. The smoke may also include other additives such as glycerin and/or propylene glycol.

An "aerosol-generating article" according to an embodiment of the invention is a product, such as a cigarette, cartridge or cigarette, preferably a disposable article, comprising a smoke material capable of generating an aerosol, such as a smoke or mist, by heating. The aerosol-generating article itself is not capable of providing electrical energy.

An "aerosol-generating device" according to an embodiment of the invention refers to a device for providing electrical energy to an aerosol-generating article, such as a smoking article.

Referring to fig. 1-8, an embodiment of the present invention provides an aerosol-generating device 100 for heating an aerosol-generating article 200 to generate an aerosol for inhalation by a user. An embodiment of the present invention provides an aerosol-generating device 100 comprising a housing 110, a heater assembly 120 and a cartridge 140, the housing 110 being arranged to receive an aerosol-generating article 200, in use a heat-generating portion of the heater assembly 120 extending into a receiving cavity 111 of the housing 110, the aerosol-generating article 200 being heatable by insertion into the receiving cavity 111 of the housing 110. Since the smoke as a smoke substance is prepared by using natural tobacco components and/or other smoke substances, a small amount of oily liquid substances including tar overflows during heating, and solid residues of the smoke substance leak out in a small amount, the liquid and solid substances remain on the cigarette accommodating cavity 111 and the heater 121 of the smoking set, and if the liquid and solid substances leak out, the liquid and solid substances enter the inner space, so that the smoke substance cannot be cleaned while being used, and particularly, the liquid substances flow into the area where a circuit board or a battery is located, so that serious damage to equipment can be caused. The present invention uses the cylindrical body 140 to surround and fix the heater assembly 120, and forms a space 160 for preventing the leakage of substances, for example, the cylindrical body 140 has an inner hollow, the heater assembly 120 is fixed in the inner hollow, the base 122 and the inner wall of the cylindrical body 140 enclose the space 160 for preventing the leakage of substances, thus, no matter the liquid substances generated by heating or the solid substances such as cut tobacco are limited in the space 160, other places are not polluted, and the damage to electronic components is further caused. In addition, the cylindrical body 140 also serves as a connection pushing mechanism 130, and the pushing mechanism 130 directly acts on the cylindrical body 140 to enable the cylindrical body 140 to be movably coupled to the shell 110, so as to drive the heater assembly 120 to withdraw from the accommodating cavity 111, and the aerosol-generating article 200 is still placed in the accommodating cavity 111, so that the separation of the heater 121 from the aerosol-generating article 200 is achieved, adhesion between the heater 121 and the heated aerosol-generating substance is avoided, and removal of the aerosol-generating article 200 is facilitated.

In an embodiment, the shape of the base 122 is adapted to the hollow interior of the cylinder 140, the upper surface of the base 122 is a complete surface that is not open, and the outer edge of the base 122 is tightly attached to the inner wall of the cylinder 140, so that the upper surface of the base 122 and the inner wall of the cylinder 140 define a space 160 for preventing leakage of the substance, and since the base 122 is tightly fitted to the cylinder 140, the residue will not leak from the contact position, so long as the base 122 and the inner wall of the cylinder 140 are not open, the leakage of the substance will not occur.

In the aerosol-generating device 100 according to the embodiment of the present invention, the housing 110 is provided with a receiving cavity 111 for receiving the aerosol-generating article 200; in an embodiment, the housing 110 has an opening 112 communicating with the receiving cavity 111 for inserting the aerosol-generating article 200 from the opening 112 into the receiving cavity 111, which opening 112 may also be a cigarette insertion opening or an insertion opening of the receiving cavity. The walls of the housing 110 defining the receiving cavity 111 may include side walls 113 and a bottom wall 114 that are interconnected to form a cup-like structure for defining the receiving cavity 111. Preferably, the shape of the receiving cavity 111 is adapted to the shape of the aerosol-generating article 200, so that the aerosol-generating article 200 is not very easily carried out of the mouth when inserted into the receiving cavity 111, nor is it squeezed to cause excessive deformation of the aerosol-generating article 200 to increase the resistance to draw.

Preferably, the pipe wall of the cylindrical body 140 extends toward the opening 112, and surrounds the periphery of the heater 121, so that the heater 121 can be protected, the space 160 for preventing the leakage of the substance can extend toward the opening 112, and the residues can be completely collected in the space 160, thereby facilitating centralized cleaning.

Preferably, the housing 110 includes an upper cover 116, and the accommodating chamber 111 is disposed in the upper cover 116, and the upper portion of the cylinder 140 is exposed when the upper cover 116 is removed, thereby facilitating cleaning.

In the aerosol-generating device 100 according to the embodiment of the present invention, the heater assembly 120 includes a heater 121 and a base 122 for fixing the heater 121, and the base 122 may fix the heater 121 by embedding, clamping, or the like, or may be integrally formed, for example, by injection molding or ceramic sintering. The heater 121 is for inserting an aerosol-generating article 200 to heat an aerosol-generating substance therein to generate an aerosol; the heater 121 comprises one or more electrical heating elements, preferably resistive materials, which upon energization convert electrical energy into thermal energy to generate heat so that the aerosol-generating substance can be heated to generate an aerosol, the electrical heating elements preferably being composited with an insulating material such as ceramic to form a needle, rod or sheet shaped heater 121 of a certain strength, the heater 121 being adapted to be at least partially inserted into the aerosol-generating substance of the aerosol-generating article 200.

In the aerosol-generating device 100 provided by the embodiment of the present invention, the pushing mechanism 130 is connected or movably coupled to the cylindrical body 140, and pushes the cylindrical body 140 to move relative to the housing 110. The pushing mechanism 130 pushes the heater 121 to slide between the heating position and the separation position under the traction of the cylinder 140. The heating position is a position where the heater 121 extends into the accommodating chamber 111, and the separation position is a position where the heater 121 exits away from the accommodating chamber 111. For example, the pushing mechanism 130 pushes the heater assembly 120 to slide between a heating position and a separating position under the action of external force, wherein the heating position is a position in which the heater 121 is fully inserted into the aerosol-generating article 200, and is a deepest position in which the heater 121 extends into the accommodating cavity 111, and at this time, the aerosol-generating article 200 can be heated to generate aerosol as long as the accommodating cavity 111 receives the aerosol-generating article; the separated position is a position in which the heater 121 has completely exited the receiving chamber 111, and the heater 121 is no longer in contact with the aerosol-generating article 200 within the receiving chamber 111, in which the heater 121 exits the furthest position away from the receiving chamber 111. After the aerosol-generating article 200 has been heated, the heater 121 is gradually withdrawn from the receiving cavity 111 during the sliding of the heater assembly 120 between the heating position to the separation position, effecting separation of the heater 121 from the aerosol-generating article 200.

Preferably, the heating position is a position where the heater 121 heats the aerosol-generating article 200, when the heater assembly 120 is in this position, awaiting insertion of the aerosol-generating article 200 into the receiving cavity 111, or already having the aerosol-generating article 200 inserted into the receiving cavity 111 awaiting heating or being heated, which position may also be referred to as an operating position. The separation position is a position in which the heater 121 is completely separated from the aerosol-generating article 200, and when the heater assembly 120 is in this position, indicating that the heater 121 has been completely separated from the aerosol-generating article 200, the aerosol-generating article 200 may be removed directly. When the heated aerosol-generating article 200 is removed, the heater assembly 120 needs to be pushed back into position extending into the receiving cavity 111, waiting for the next operation.

The movement mechanism and movement pattern of the present invention will be described in detail with reference to fig. 9-13 in conjunction with the embodiments described above in the various movement positions. In an embodiment, the pushing mechanism 130 includes a push button 131, the push button 131 being movably coupled to the housing 110. For example, the push button 131 may slide along the housing 110, for convenience of description, the direction in which the heater assembly 120 moves toward the opening 112 is referred to as a first direction 141, and the direction in which the heater assembly 120 withdraws from the accommodating chamber 111 is referred to as a second direction 142, and it is apparent that the first direction 141 is also the direction in which the heater assembly 120 moves from the separated position to the heating position, since the accommodating chamber 111 is fixed with respect to the housing 110, as the heater assembly 120 is pushed upward, that is, the heater assembly 120 is pushed toward the aerosol-generating article 200; the second direction 142 is also the direction of movement of the heater assembly 120 from the heating position to the separating position, in that the heater assembly 120 is retracted, i.e. the heater assembly 120 is moved away from the aerosol-generating article 200. The portion of the push button 131 disposed outside the housing 110 may be designed to facilitate finger force, by providing protrusions or texturing to increase friction when the push button 131 is operated.

Preferably, the housing 110 is provided with a sliding groove for defining the push button 131, the push button 131 can slide along the sliding groove under the action of an external force, for example, the sliding groove is in a straight shape, the opening direction of the straight shape is parallel to the first direction 141 and the second direction 142, and the sliding process of the push button 131 in the sliding groove drives the cylinder 140 and the heater assembly 120 to move. The position of the push button 131 in the chute corresponds to the position of the heater assembly 120, e.g., movement of the push button 131 from one end of the chute to the other pulls the heater assembly 120 to slide between the heating position and the disengaged position.

In an embodiment, the movement direction of the push button 131 is consistent with the movement direction of the heater assembly 120 (see fig. 9), for example, the push button 131 may be directly and fixedly connected to the heater assembly 120, the first position and the second position of the chute (not shown) may be two ends of a straight chute, and the push button 131 moves from the bottom end to the top end of the chute, that is, pushes the push button 131 along the first direction 141 to drive the heater assembly 120 to move from the separation position to the heating position; the push button 131 moves from the top to the bottom of the chute, i.e., pushing the push button 131 in the second direction 142 moves the heater assembly 120 from the heating position to the separation position.

In an embodiment, the pushing mechanism 130 further includes a gear 132 for coupling the base 122 and the push button 131, so that the base 122 and the push button 131 are movably coupled, and transmission of pushing force can be achieved in the case that two movement directions are not completely identical (see fig. 10). For example, the push button 131 may move in a direction opposite to the direction of movement of the heater assembly 120. The first position and the second position of the chute may be two ends of a linear chute respectively, and the push button 131 moves from the bottom end to the top end of the chute, that is, the push button 131 is pushed along the first direction 141 to drive the heater assembly 120 to move from the heating position to the separating position; the push button 131 moves from the top to the bottom of the chute, i.e., pushing the push button 131 in the second direction 142 moves the heater assembly 120 from the separated position to the heating position. Preferably, the gear 132 includes a threaded opening, an external thread is disposed on the cylindrical body 140, an external thread is disposed on the push button 131, the gear 132 engages with the external threads on the cylindrical body 140 and the push button 131, respectively, the external threads on the cylindrical body 140 and the external threads on the push button 131 are substantially parallel, the gear 132 clamps the external threads, and the thrust of the push button 131 is transmitted to the cylindrical body 140 through the gear 132 and reverses the movement directions of the two. It should be particularly noted that the chute may be arcuate, helical, etc., and that the movement of the heater assembly 120 in the first and second directions 141, 142 may be accomplished by providing a combination of drive members to form different gears 132 to transfer the thrust.

In an embodiment, the pushing mechanism 130 pushes the heater assembly 120 back, i.e. pushes the heater assembly 120 from the separated position to the heating position, when the heater 121 abuts the aerosol-generating article 200 and ejects or pushes it from the receiving cavity 111 a distance for easy removal by the user if the aerosol-generating article 200 is not removed.

In an embodiment, the aerosol-generating device 100 may further comprise an extraction assembly 150, the extraction assembly 150 being configured to assist in pushing the aerosol-generating article 200 out of the receiving cavity 111 after the heater assembly 120 is withdrawn from the receiving cavity 111, preferably the pushing mechanism 130 being configured to trigger the extraction assembly 150 when pushing the heater assembly 120 out of the receiving cavity 111, the extraction assembly 150 being configured to push the aerosol-generating article 200 along the length of the receiving cavity 111, i.e. along the first direction 141, to eject it directly or to push it a distance, for easy removal by a user.

The extraction assembly 150 is used to assist the aerosol-generating article 200 in disengaging the receiving cavity 111, preferably the extraction assembly 150 comprises a shoe 151 abutting the air inlet end of the aerosol-generating article 200 and a linkage assembly for triggering the extraction assembly 150, the shoe 151 being movable along the length of the receiving cavity 111, the length of the receiving cavity 111 being the extension between the bottom of the receiving cavity 111 and the opening 112, and the direction of insertion and removal of the aerosol-generating article 200 from the receiving cavity 111. In an alternative embodiment, the shoe 151 may be part of the housing cavity 111, e.g., instead of the bottom wall 114.

Referring to fig. 11 and 12, the linkage assembly includes a limiting member 152 for limiting the bottom of the accommodating cavity 111 to the bottom of the accommodating cavity 111, and a traction member 153 for generating a force with the limiting member 152, where when the heater 121 approaches or reaches the separation position, the traction member 153 pulls the limiting member 152 to separate from limiting the bottom of the accommodating cavity 151. In a preferred embodiment, the limiting member 152 is a movable hanging buckle detachably connected to the base 151, that is, the movable hanging buckle limits the base 151 to the bottom of the accommodating cavity 111, and when the pushing mechanism 130 pushes the heater assembly 120 to a position away from the accommodating cavity 111, the pushing mechanism 130 pulls the movable hanging buckle to be separated from the base 151. The traction member 153 may be a part of the cylinder 140 or connected to the cylinder 140, when the heater 121 is approaching or reaching the separation position, the traction member 153 moves together with the cylinder 140 to approach the movable hanging buckle, and then the limiting action on the bottom bracket 151 is released by any one of magnetic attraction, adhesion and buckling, and then the bottom bracket 151 moves towards the direction approaching the opening 112 of the accommodating cavity 111 under the action of external force. In this embodiment, the elastic member 157 is preferably used to pull the bottom support 151 to move away from the bottom of the accommodating cavity 111, for example, the elastic member 157 is a tension spring, one end of the elastic member is connected to the opening 112 of the accommodating cavity 111, and the other end of the elastic member is connected to the bottom support 151, so that the bottom support 151 is pulled to move toward the opening 112 by providing tension, and the bottom support 151 moves toward the opening 112 to support the aerosol-generating article 200 away from the accommodating cavity 111 for assisting detachment. When the auxiliary aerosol-generating article 200 is inserted into the receiving cavity 111, the aerosol-generating article 200 and the shoe 151 are pushed together to the bottom of the receiving cavity 111 by an external force, so that the shoe 151 is buckled with the movable hanging buckle, and thus the shoe 151 cannot be "reset", i.e. the shoe 151 cannot move towards the opening 112 until the shoe 151 is triggered by the pushing mechanism 130 to be separated from the movable hanging buckle.

In an embodiment, the tube wall of the housing 110 defining the receiving cavity 111 comprises a side wall 113 and a bottom wall 114, which are interconnected to form a cup-like structure, the bottom wall 114 being provided with holes for allowing the insertion of the heater 121 into the aerosol-generating article 200 received in the receiving cavity 111. The aerosol-generating article 200 further comprises a filter 210 arranged at a gas outflow end of the aerosol-generating article 200, opposite to which is a gas inflow end, which also becomes a gas inlet end. When the aerosol-generating article 200 is disposed in the receiving cavity 111 of the aerosol-generating device 100, the filter 210 may be exposed from the opening 112 for the user to inhale, and the gas inflow end abuts against the bottom wall 114, so that the bottom wall 114 is provided with holes for air to flow into the aerosol-generating article 200. As the user draws, the heater 121 heats the aerosol-generating substance to form an aerosol containing aerosol. The aerosol is then transported in a flow of air into the mouth of the user. Because air flows through and adjacent to the aerosol-generating substance, air flows through the holes provided in the bottom wall 114, the size and shape of the holes being used to manage the air flow and thus the characteristics of the aerosol.

Preferably, the movable hanging buckle can move along the direction perpendicular to the length direction of the accommodating cavity 111, the length direction of the accommodating cavity 111 is also the extending direction of the heater 121, the bottom support 151 is limited at the bottom of the accommodating cavity 111 when the movable hanging buckle is close to the accommodating cavity 111, and the movable hanging buckle is separated from the bottom support 151 when the movable hanging buckle is far away from the accommodating cavity 111.

In an embodiment, the linkage assembly includes a first member 154 disposed on the shoe, and a second member 155 coupled to the first member 154 when the heater 121 approaches or reaches the separated position, it being understood that the direction of movement of the second member 155 after coupling with the first member 154 is the same. For example, the second element 155 may be part of the cartridge 140 or may be coupled to the cartridge 140 such that the second element 155 is in the same direction of movement as the cartridge 140, and the second element 155 may be coupled to the first element 154 as the cartridge 140 pulls the heater assembly 120 in the first direction 141, the second element 155 gradually approaching the first element 154 until the heater 121 approaches or reaches the disengaged position; the second member 155 then moves with the first member 154 along with the cartridge 140 in the second direction 142, which may effect movement of the shoe 151 away from the bottom of the receiving cavity 111, thereby helping to effect exit of the aerosol-generating article 200 from the receiving cavity 111.

Preferably, the second element 155 and the first element 154 are acted upon by any one of magnetic attraction, adhesion, and snap-fit, e.g. the second element 155 and the first element 154 may be coupled by magnetic attraction, which may also urge the shoe 151 and the aerosol-generating article 200 to move away from the bottom of the receiving cavity 111 when the cartridge 140 is moved in the second direction 142. For example, the first element 154 is a magnet 154 'disposed on the base 151, the second element 155 is an iron ring 155' sleeved outside the accommodating cavity 111, the iron ring 155 'abuts against the top end of the cylindrical body 140 under the thrust action of a spring 156, one end of the spring 156 is connected to the opening 112 communicating with the accommodating cavity 111, the other end of the spring 156 is connected to the iron ring 155', and the spring 156 provides continuous thrust to push the iron ring 155 'against the top end of the cylindrical body 140 and move the iron ring 155' together with the cylindrical body 140. When the heater 121 approaches or reaches the separation position, the magnet 154 'is attracted to the iron ring 155', and the magnetic attraction force can also push the shoe 151 and the aerosol-generating article 200 to move away from the bottom of the accommodating chamber 111 when the cylindrical body 140 moves from the first direction 141 to the second direction 142.

Of course, the combination may be replaced by a sticking manner such as a velcro, an adhesive, or a fastening manner such as a clipping position, a buckling position, or the like, for example, the first element 154 is a thimble, the second element 155 is a bayonet provided on the inner wall of the cylindrical body 140, and when the heater 121 reaches the separation position, the thimble falls into the bayonet, and then is combined together, and when the cylindrical body 140 moves along the second direction 142, the collet 151 and the aerosol-generating article 200 are driven to move toward the opening 112 of the accommodating cavity 111.

Referring to fig. 13, in the aerosol-generating device 100 according to the embodiment of the present invention, the pushing mechanism 130 includes a knob 135, and the knob 135 is movably coupled to the housing 110. The knob 135, during rotation along the housing 110, pushes the heater assembly 120 to slide between a position extending into the receiving cavity 111 and a position withdrawn away from the receiving cavity 111. For example, the outer circumference of the cylindrical body 140 is provided with an external thread, the knob 135 is cylindrical, the inner circumference thereof is provided with an internal thread, and the external thread on the cylindrical body 140 is engaged with the internal thread on the knob 135. The knob 135 provided at the outer circumference of the housing 110 may be designed to facilitate finger force, by providing protrusions or texturing to increase friction when the knob 135 is operated. The movement of the other structures of this embodiment is identical to that of the previous embodiment except that the pushing action of the knob 135 on the heater assembly 120 is different, and will not be described again.

In one embodiment, the pushing mechanism 130 may first push the cylinder 140 in the first direction 141, and then the cylinder 140 moves in the second direction 142 until it is "returned". The tube 140 may push the tube wall defining the receiving cavity 111 and the aerosol-generating article 200 inserted therein together in a direction towards the opening 112 during movement in the first direction 141, effecting pushing out of the aerosol-generating article 200. In order to avoid that the tube 140 is pulled back again during the "return" movement of the tube 140 in the second direction 142, a limiting mechanism may be provided to fix the tube wall defining the receiving chamber 111 such that the tube 140 and the heater 121 are both moved back, but the tube wall defining the receiving chamber 111 and the aerosol-generating article 200 are not returned, resulting in a separation of the aerosol-generating article 200 from the heater 121.

In one embodiment, referring to fig. 7, the cylindrical body 140 is provided with a notch 143, and the protrusion 123 on the base 122 falls into the notch 143 and is limited. The base 122 is provided with the protrusions 123, the number of the protrusions 123 can be the same as that of the notches 143, the protrusions 123 are matched with the shapes of the notches 143, and the protrusions 123 are limited and cannot rotate when being mounted in the notches 143.

In one embodiment, the slot 143 extends along the length of the barrel 140 to the end of the barrel 140 so that the projection 123 on the base 122 can slide and fit all the way along the slot 143.

The rotation of the motor 134 drives the screw rod 133 to rotate, and the screw rod 133 further pushes the cylinder 140 to move along the first direction 141 and the second direction 142. In order to prevent the rotation of the screw rod 133 from rotating the cylinder 140, a cross beam (not shown) is disposed on the housing 110, and is inserted into the slot 143, and the extending direction of the cross beam is perpendicular to the length direction of the cylinder 140, so that the rotation of the cylinder 140 is prevented, and the cross beam can only move in the first direction 141 and the second direction 142, and slides along the slot 143 during the movement of the cylinder 140. For example, the two notches 143 are disposed opposite to each other, and the cross beam passes through the two notches 143 and then penetrates the tubular body 140 perpendicular to the longitudinal direction of the tubular body 140.

Preferably, the connector 144 is fixed to an end of the cylindrical body 140 remote from the heater 121, and the cylindrical body 140 is hollow, and in order to fix the base 122, a fixing auxiliary 145 may be directly provided in the hollow of the cylindrical body 140, one end abuts against the base 122 of the heater 121, the other end abuts against the connector 144, and the fixing auxiliary 145 is fixed by connecting the connector 144, and the base 122 is restrained from moving at the extreme end of the notch 143. In addition, the fixing aid 145 preferably also has an internal hollow, so that the screw 133 has a space into which it can enter during rotation.

Other forms of pushing mechanism 130, such as pneumatic pump, hydraulic pump, electromagnet, etc., can also fully achieve the aforementioned purpose, for example, directly use pneumatic pump, hydraulic pump to replace motor 134, use transmission rod to replace screw rod 133 to connect with connecting piece 144, and then push cylinder 140; in the embodiment using an electromagnet as the pushing mechanism 130, a replaceable electromagnet is used to replace the motor 134, a magnetic element is used to replace the connector 144, when the electromagnet attracts the magnetic element, the cylindrical body 140 is pushed to move in the first direction 141, when the electromagnet repels the magnetic element, the cylindrical body 140 is pushed to move in the second direction 142, the electromagnet can change the magnetic field direction preferably, the magnetic field direction can be changed by changing the current flow direction, and the control of the movement direction of the cylindrical body 140 is conveniently realized.
