In particular, the aerosol-generating article S may have a diameter of from 2 to 15mm. Further, the surface of the aerosol-generating article S is also designed with through holes, the diameter and filling ratio of which can be designed according to different air flow resistance requirements to ensure optimal aerosol release.
The specific structure and function of the aerosol-generating device can be seen in the specific structure and function of the aerosol-generating device provided in any of the following embodiments.
As shown in fig. 2 and 3, the aerosol-generating device includes a housing 11, a receiving cavity 12 disposed in the housing 11, a delivery assembly, a heating assembly 14, and a mouthpiece 15.
The housing 11 includes a main body 111 and a cover 112, the cover 112 is disposed on the main body 111 and cooperatively defines a hollow cavity, and is configured as an outer surface of the aerosol generating device to protect components in the hollow cavity; of course, the housing 11 may also be combined in a left-right or front-back snap-together manner, and the structure of the housing 11 is not limited in the present application. The receiving cavity 12, the conveying module and the heating module 14 are specifically received in the hollow cavity. The suction nozzle 15 is disposed on the housing 11, and is formed with an air outlet channel 151 for communicating with the outside atmosphere, and the user sucks the aerosol formed by atomization through the suction nozzle 15. Of course, the suction nozzle 15 can also be defined directly by the housing 11. In this embodiment, the suction nozzle 15 is a cylindrical pipe inserted into a through hole in the top wall of the main body 111.
As shown in fig. 3, the receiving cavity 12 has a receiving cavity 121, and the receiving cavity 121 is used for receiving the aerosol-generating product S; specifically, the aerosol-generating products S in the aerosol-generating system are stacked in the depth direction of the housing cavity 121. In one embodiment, the receiving cavity 12 is a separate structure from the housing 11, and is detachably connected to the housing 11 to realize disposable disposal of the receiving cavity 12, so that the receiving cavity 12 can be easily taken out after the received aerosol-generating product S is consumed, so as to realize rapid filling of a new aerosol-generating product S; or to replace a new receiving cavity 12 containing the aerosol-generating article S, thereby achieving better replaceability of the receiving cavity 12.
The accommodating cavity 121 may be cylindrical; the circumferential shape of the housing cavity 121 matches the circumferential shape of the aerosol-generating article S and the aperture of both are substantially the same or the aperture of the housing cavity 121 is slightly larger than the aperture of the aerosol-generating article S to facilitate loading or unloading of the aerosol-generating article S into or out of the housing cavity 121 while preventing the aerosol-generating article S from wobbling in the housing cavity 121. Specifically, the material of the receiving cavity 12 may be a harmless metal material, such as 6-series aluminum alloy, stainless steel, or a harmless plastic material, such as Polyetheretherketone (PEEK).
As shown in figure 3, the transport assembly is for batch transport of aerosol-generating articles S to an aerosolization area 183. Specifically, when the aerosol-generating article S includes a plurality of aerosol-generating articles S arranged in a stack, the conveying assembly is specifically configured to convey the plurality of aerosol-generating articles S to the atomizing area 183 sequentially, that is, convey a preset number of aerosol-generating articles S to the atomizing area 183 at a time, instead of conveying all the aerosol-generating articles S in the housing cavity 121 to the atomizing area 183 at a time. It will be appreciated that where the aerosol-generating article S is a liquid substrate, the transport assembly may be controlled to transport the portion of the aerosol-generating article S in the housing chamber 121 to the aerosolization area 183 each time a portion of the aerosol-generating article S is dispensed from the housing chamber 121 to the aerosolization area 183 to deliver the aerosol-generating article S in the housing chamber 121 to the aerosolization area 183 a plurality of times.
In one embodiment, as shown in fig. 2 or 3, the delivery assembly includes a rotary member 13, a power element (not shown), and a control circuit (not shown). Wherein the rotary member 13 is connected to a powered element for driving rotation of the rotary member 13 to deliver the aerosol-generating article S to the aerosolization area 183 by rotation of the rotary member 13. Wherein, the rotating member 13 can be a rotatable plate member or a movable robot arm or robot hand, etc.; the power element may be a motor, a pump, etc. Of course, in other embodiments, the rotating member 13 may be driven by a manual mechanical mechanism, for example, a portion of the rotating member 13 extends outside the housing 11 and is manually driven to rotate. This enables the use of a powered element to be reduced to further reduce the volume of the aerosol-generating device. The control circuitry is electrically connected to the motive element and the heating assembly 14, respectively, for controlling the motive element to cause the rotary member 13 to move the aerosol-generating article S to the aerosolization area 183 and for controlling the heating assembly 14 to heat the aerosol-generating article S of the aerosolization area 183 after the rotary member 13 has delivered the aerosol-generating article S to the aerosolization area 183. Wherein, the control circuit can be powered by a built-in battery pack; and the control circuit may further be used to control the output of a continuous or pulsed laser of the heating assembly 14, while the power output profile of a single puff may be controlled to achieve a better aerosol experience.
As shown in fig. 2, 3, the heating assembly 14 is used to heat and atomize the aerosol-generating article S in the aerosolization area 183. The heating assembly 14 is heated by thermal radiation such as laser heating, microwave heating, infrared heating, etc., and due to the non-contact and instantaneous heating characteristics, a safer technical solution of reducing harm, heating, and non-combustion of the aerosol-generating article S can be achieved. In the present application, the heating assembly 14 is illustrated as the heating assembly 14, but the present application is not limited thereto. The heating assembly 14 may be used to emit a laser for heat atomising the aerosol-generating article S at an atomisation region 183 to produce an aerosol.
The heating assembly 14 includes a semiconductor laser chip, which may be an edge-emitting semiconductor laser chip of gallium arsenide or indium phosphide or a vertical-cavity surface semiconductor laser chip. Specifically, the present application adopts an edge-emitting Laser (EEL) chip or a Vertical-cavity Surface-emitting Laser (VCSEL) chip of a totally enclosed Package (TO) or a Quad Flat No-leads Package (QFN) TO ensure the stable reliability of the long-term operation of the aerosol generating device by using the hermetically packaged semiconductor Laser chip. The package body can adopt a passive conduction cooling scheme, for example, a TO or QFN package structure is directly packaged on a heat dissipation metal heat sink TO assist the laser emission module in heat dissipation. Of course, in other embodiments, the aerosol-generating device further comprises a heat-dissipating element (not shown) disposed upstream of the heating assembly 14 along the airflow path of the aerosol-generating device to dissipate heat from the heating assembly 14. The heat dissipation element may be a heat dissipation fin. The laser packaging module and the metal radiating fin are fixed by adopting solidifiable silver adhesive and metal solder which are certified by ROHS.
The output peak power of the semiconductor laser chip is 1-30W, and the wavelength of the semiconductor laser chip is 800-1500nm. The wavelength of the emitted laser of the semiconductor laser chip is about 800-1500nm, so that the semiconductor laser chip has obvious particle property, and the beam quality and the beam directivity of the laser beam are strong. Heating the aerosol-generating article S with a laser therefore enables rapid heating based on the physical characteristics typical of lasers. Further, due to the optical properties of the laser, selective direct non-contact heating of the aerosol-generating article S is possible, which may keep the aerosol taste fresh and stable. Compared with other heating modes, the laser heating device does not need to be specially additionally provided with a laser shielding part, and is simple in structure and low in cost. In particular, the semiconductor laser chip has a volume of less than 4 cubic centimeters, reducing the volume of the heating assembly 14 and enabling a miniaturized, commercially viable heating arrangement for the aerosol-generating article S.
In a particular embodiment, the laser forms a spot on the surface of the aerosol-generating article S that is substantially the same as or slightly smaller than the diameter of the aerosol-generating article S, with the energy distribution of the spot being in the TOP HAT mode; the uniformity of the light energy is more than 70%, and the uniformity of heating is effectively ensured.

In addition, by providing the heating assembly 14 for emitting laser light to heat and atomise the aerosol-generating article S at the atomisation region 183 using the laser light. The aerosol generating product S is heated by laser, and due to the characteristics of non-contact and instant heating of the laser, a safer technical scheme of harm reduction, heating and non-combustion of the aerosol generating product S can be realized; at the same time, by providing the location at which the aerosol-generating article S is stored in a zone with the aerosolization area 183 and then delivering the aerosol-generating article S to the aerosolization area 183 in batches by the delivery assembly, such that the heating assembly 14 heats and aerosolizes only the aerosol-generating article S delivered to the aerosolization area 183 at a time; in this way, the aerosol generating product S with the preset heating amount each time can be selected according to the actual wavelength of the laser, the problem that the aerosol generating product S far away from the heating component 14 has poor heating effect due to the fact that the laser is absorbed by the aerosol generating product S due to the wavelength characteristic of the laser is avoided, the heating uniformity of the aerosol generating product S is good, and the atomization utilization rate is high; meanwhile, after the aerosol-generating articles S in the atomization region 183 are atomized, the aerosol-generating articles S which are not atomized are conveyed to the atomization region 183 to be atomized continuously, so that only a fixed amount of aerosol-generating articles S can be conveyed for atomization at each time according to the amount of the aerosol-generating articles S corresponding to each opening or the preset number of openings, and the freshness and the consistency of the mouthfeel of the aerosol sucked by a user can be further maintained.
As shown in fig. 3, the aerosol-generating device further includes a first driving element 16, the first driving element 16 is disposed in the receiving cavity 121 and is configured to drive the aerosol-generating products S in the receiving cavity 121 to move out of the receiving cavity 121 in sequence; by providing the first drive element 16, the aerosol-generating device can be maintained in a horizontal or non-horizontal position, and the aerosol-generating article S in the housing chamber 121 can be moved out of the housing chamber 121 by the drive force of the first drive element 16. In particular, the first drive element 16 drives one aerosol-generating article S at a time out of the receiving cavity 121. In this embodiment, the transport assembly is particularly for transporting aerosol-generating articles S that are moved out of the receiving cavity 121 to the aerosolization area 183.
In a particular embodiment, the first drive element 16 is a resilient member, such as a spring or torsion spring or the like, disposed between the bottom wall of the receiving cavity 12 and the plurality of aerosol-generating articles S. Of course, the first driving element 16 may also be a rotating shaft or a piston, and is connected to a driving source, such as a motor or a pump; to drive the first drive element 16 to move by a drive source and to drive one aerosol-generating article S at a time to move out of the receiving cavity 121.
Wherein aerosol-generating article residue S' is formed as a result of the aerosol-generating article S being consumed, i.e. after the aerosol-generating article S has been atomised; to avoid aerosol-generating article residue S' affecting the atomisation effect of aerosol-generating article S subsequently delivered to the atomisation region 183; the transport assembly is further also used to remove aerosol-generating article residue S' from the aerosolization area 183 after the aerosol-generating article S has been consumed. The aerosol-generating article residue S' may also be an outer wrapper for the aerosol-generating article S, such as an aluminium foil or the like. It will be appreciated that the aerosol-generating article S, if a liquid substrate, is substantially free of aerosol-generating article residue S', and need not be removed; however, a recovery vessel is required at the atomizing area 183 to contain the liquid substrate.
In this embodiment, as shown in fig. 2 and 3, in order to further perform a secondary recycling of the aerosol-generating article residue S ', the aerosol-generating device further comprises a recycling chamber 17, the recycling chamber 17 having a recycling chamber 171, and the transport assembly in particular transports the aerosol-generating article residue S' from the nebulization area 183 to the recycling chamber 171 for recycling.

Specifically, the recycling cavity 17 and the accommodating cavity 12 may be arranged side by side along the radial direction of the housing 11 to reduce the product volume. Meanwhile, the recycling cavity 171 may also be cylindrical; and the circumferential shape of the recovery cavity 171 matches the circumferential shape of the aerosol-generating article residue S ' and the aperture of both are substantially the same or the aperture of the receiving cavity 121 is slightly larger than the aperture of the aerosol-generating article residue S ', so that the aerosol-generating article residue S ' falls into the recovery cavity 171. Specifically, the material of the recycling cavity 171 may be a harmless metal material, such as 6-series aluminum alloy, stainless steel, etc., or a harmless plastic material, such as Polyetheretherketone (PEEK). The recycling cavity 17 and the accommodating cavity 12 can be formed integrally, and only two different cavities are defined. Of course, the receiving cavity 12 and/or the recycling cavity 17 may also be directly defined by the housing 11, i.e. the receiving cavity 121 and/or the recycling cavity 171 are constructed by the housing 11.
Further, as shown in fig. 2 to 4, fig. 4 is a schematic diagram of a partial internal structure of an aerosol-generating system provided in an embodiment of the present application; the aerosol-generating device further comprises a carrier plate 18. A side surface of the carrier plate 18 facing the suction nozzle 15 forms an atomizing area 183 for carrying the aerosol-generating article S. The material of the carrier plate 18 can be a safe and non-toxic metal or plastic.
In one embodiment, as shown in FIG. 4; the receiving cavity 12 and the recovery cavity 17 are both located on a side of the carrier plate 18 facing away from the suction nozzle 15 to reduce the overall volume of the aerosol-generating device. In this embodiment, in order to ensure that the aerosol-generating product S in the receiving cavity 121 can move to the atomizing area 183 of the carrier plate 18 and the aerosol-generating product residue S' in the atomizing area 183 can smoothly enter the recovery cavity 171, the carrier plate 18 is provided with a first opening 181 communicating with the receiving cavity 121, so that the aerosol-generating product S in the receiving cavity 121 can reach the side of the carrier plate 18 facing the suction nozzle 15 through the first opening 181; and/or the carrier plate 18 is provided with a second opening 182 communicating with the recovery chamber 171 for the aerosol-generating product residue S' to enter the recovery chamber 171. This can prevent the aerosol-generating article S from falling to other locations of the aerosol-generating device during movement, resulting in waste or contamination. Specifically, the first opening 181 faces the opening of the storage chamber 121 in the longitudinal direction of the housing 11, and the second opening 182 faces the opening of the recovery chamber 171 in the longitudinal direction of the housing 11.
In this embodiment, as shown in fig. 2-4, to facilitate assembly and reduce the volume of the aerosol-generating device; the heating element 14 and the receiving cavity 12 are located on the same side of the carrier plate 18, and the portion of the carrier plate 18 corresponding to the atomization region 183 is made of an optically transparent material; in this way, the heating assembly 14 is able to directly irradiate and heat the aerosol-generating article S in the atomisation region 183 through the carrier plate 18, which enables safe non-contact heating to be achieved compared to other heating arrangements in which the heat-conducting medium is first heated and then the aerosol-generating article S is heated by heat conduction through the heat-conducting medium, and heating can be done instantaneously, with more uniform heating. Wherein, the optical transparent material can be fused quartz or sapphire stone. Of course, the heating element 14 can also be disposed on the side of the carrier plate 18 facing the suction nozzle 15, in this embodiment, the carrier plate 18 will not block the laser, and the material of the portion of the carrier plate 18 corresponding to the atomizing area 183 is not limited.
In this embodiment, the rotating member 13 may be a plate and is rotatably connected to a side surface of the carrying plate 18 facing the suction nozzle 15, so as to move the aerosol-generating product S outside the receiving cavity 121 to the atomizing area 183 along the surface of the carrying plate 18, and move the aerosol-generating product residue S' from the atomizing area 183 to the recovery cavity 171.
Specifically, referring to fig. 2, fig. 3 and fig. 5, fig. 5 is a schematic position diagram of the rotating element 13, the bearing plate 18, the accommodating cavity 12 and the recycling cavity 17 according to an embodiment of the present disclosure. The surface of the rotating member 13 facing the carrier plate 18 has at least one receiving groove 132, and the bottom wall or the side wall of the receiving groove 132 has an atomizing hole 131. Wherein the at least one receiving slot 132 is adapted to receive and retain the aerosol-generating article S outside the receiving cavity 121. The rotary member 13 holds the aerosol-generating article S by the receiving slot 132 during rotation to move the aerosol-generating article S to the aerosolization area 183; and further moves aerosol-generating article residue S' atomized within the receiving cavity 132 from the atomization zone 183 to the second opening 182 and into the recovery chamber 171. The atomization holes 131 communicate with the storage groove 132, and the aerosol-generating product S in the storage groove 132 moves to the atomization region 183 and the aerosol generated by atomization flows out through the atomization holes 131. As shown in fig. 5, the atomization holes 131 include a plurality of micropores disposed at intervals; therefore, aerosol can be ensured to flow out of the accommodating groove 132 and enter the air outlet channel 151, and the bottom wall of the accommodating groove 132 can be directly utilized to shield laser so as to reduce the risk of personnel safety caused by overflow of high-directivity laser from the shell 11 as much as possible; meanwhile, the use of laser shielding parts can be reduced, the structure is simple, and the cost is low. Of course, referring to fig. 6, fig. 6 is a schematic position diagram of the rotating member 13, the bearing plate 18, the accommodating cavity 12 and the recycling cavity 17 according to another embodiment of the present disclosure; the aperture of the atomizing aperture 131 may be slightly smaller than the aperture of the receiving slot 132, i.e. slightly smaller than the diameter of the aerosol-generating article S, in which case the atomizing aperture 131 is a single larger through hole; in this embodiment, the aerosol-generating product S can be restrained by the storage groove 132, and the aerosol-generating product residue S 'in the storage groove 132 can be easily applied with a force by the outside through the large atomization holes 131, so that the aerosol-generating product residue S' can fall from the storage groove 132.
In particular, the depth of the receiving well 132 may be matched to the thickness of one aerosol-generating article S to ensure that only one aerosol-generating article S enters the receiving well 132 at a time, one aerosol-generating article S being delivered at a time by the rotary member 13, thereby enabling the heating element 14 to heat-atomise only one aerosol-generating article S at a time, such that after the aerosol-generating article S has been consumed by a user between 1 and 5 puffs, a new aerosol-generating article S can be atomised, thereby ensuring consistency of the mouthfeel of the aerosol before and after a user puffs; meanwhile, the laser with shorter wavelength can be ensured not to be absorbed by the aerosol generating product S in the process of heating the aerosol generating product S, so that the heating uniformity and the atomization efficiency can be effectively improved, and the taste of the aerosol is fresh and consistent.
Of course, the depth of the receiving groove 132 may be the same as the thickness of two or three aerosol-generating articles S, and may be specifically set according to the penetration wavelength of the laser and the user' S requirements. For example, the thickness of the aerosol-generating article S may be made smaller, and the sum of the thicknesses of the aerosol-generating articles S may be the same as the penetration distance of the laser beam. In this way, a plurality of aerosol-generating articles S of different flavors can be stacked one on top of the other and pushed into the receptacle 132, and delivered to the atomizing area 183 for thermal atomization, thereby enriching the user' S smoking experience.
Referring to fig. 7, fig. 7 is a schematic view illustrating positions between the rotary member 13 and the carrier plate 18, the accommodating cavity 12 and the recycling cavity 17 according to another embodiment of the present disclosure, in order to prevent the aerosol-generating product S in the accommodating cavity 121 from being ejected out of the accommodating cavity 121 under the driving action of the first driving element 16 after the accommodating groove 132 is removed from the first opening 181; the rotary member 13 may further be aligned with the first opening 181 at a position other than the position of the receiving slot 132, and the rotary member 13 blocks the first opening 181, so that the aerosol-generating product S in the receiving cavity 121 cannot move out of the receiving cavity 121 under the blockage of the rotary member 13.
The following describes the rotation process of the rotary member 13: referring to fig. 5 and 8, fig. 8 is a schematic structural view illustrating the receiving groove 132 of the rotating member 13 aligned with the first opening 181; when the housing groove 132 of the rotary member 13 is aligned with the first opening 181, as shown in fig. 5 and 8, the urging force of the rotary member 13 on the aerosol-generating product S in the housing cavity 121 is eliminated, and at this time, the aerosol-generating product S in the housing cavity 121 is moved out of the housing cavity 121 by the first driving element 16 and is housed in the housing groove 132. The rotary member 13 starts to rotate and conveys the aerosol-generating product S in the housing groove 132, and as shown in fig. 2, the aerosol-generating product S housed in the housing groove 132 can move to the atomization region 183 with the rotation of the rotary member 13 to be atomized, and at this time, the first opening 181 is closed by the rotary member 13. After the aerosol-generating article S in the receiving slot 132 has been completely consumed to form aerosol-generating article residue S ', see fig. 9, fig. 9 is a schematic view of the structure of the rotary member 13 conveying the aerosol-generating article residue S' to the second opening 182; the rotary member 13 continues to rotate, the aerosol-generating product residue S 'is conveyed to the second opening 182, and when the accommodation groove 132 and the second opening 182 are aligned, the aerosol-generating product residue S' accommodated in the accommodation groove 132 falls from the accommodation groove 132, and falls into the recovery chamber 171 through the second opening 182 for secondary recovery, and at this time, the first opening 181 is still blocked by the rotary member 13. Then, the rotary member 13 is rotated in the reverse direction, so that the accommodating groove 132 of the rotary member 13 is aligned with the first opening 181, and the other aerosol-generating product S in the accommodating cavity 121 is moved out of the accommodating cavity 121 by the first driving element 16 and is accommodated in the accommodating groove 132.
In one embodiment, as shown in fig. 2, 8 and 9, the rotary member 13 is provided with only one receiving groove 132; the rotating part 13 is in a fan shape, and the fan-shaped rotating part 13 rotates along one end part or edge of the fan shape; the radian corresponding to the fan-shaped rotating member 13 is not less than the radian corresponding to the first opening 181 and the second opening 182 along the rotating path of the rotating member 13, so that the first opening 181 can be still covered by the rotating member 13 when the accommodating groove 132 of the rotating member 13 is aligned with the second opening 182, and the aerosol-generating product S in the accommodating cavity 121 is prevented from moving from the first opening 181 to the outside of the accommodating cavity 121 under the driving force of the first driving element 16; the following examples are given as examples. In particular, in this embodiment, the rotary member 13 can rotate along the following path: the receiving groove 132 of the rotating member 13 rotates counterclockwise from the position of the first opening 181 shown in fig. 8 to the atomizing area 183 shown in fig. 2, and then continues to rotate counterclockwise to the position of the second opening 182 shown in fig. 9; thereafter, continued access to the aerosol-generating article S of the receiving cavity 121 is obtained clockwise through the aerosolization area 183 to the position of the first opening 181 of fig. 2.
Of course, in other embodiments, the rotary member 13 may have a disk shape, and the rotary member 13 rotates along the center of the disk; in this embodiment, when the receiving groove 132 of the rotating member 13 is moved to any position different from the first opening 181, the rotating member 13 can block and shield the first opening 181, and the rotating member 13 can rotate in the same direction all the time, and specifically, the rotating direction of the rotating member 13 is not limited.
Referring to fig. 10 to 11, fig. 10 is a schematic diagram illustrating a positional relationship between a rotating member having three receiving slots and the first opening, the second opening and the atomizing area after rotating for a certain angle;
FIG. 11 is a schematic diagram showing the positional relationship between the rotary member and the first and second openings and the atomizing area after the rotary member is rotated by a certain angle on the basis of FIG. 10; in other embodiments, the rotating member 13 may also have at least three receiving slots 132, at least three receiving slots 132 are spaced along the rotation path of the rotating member 13, and the spacing distance between adjacent three receiving slots 132 along the rotation path of the rotating member 13 is consistent with the spacing distance between the first opening 181, the atomizing area 183 and the second opening 182 along the rotation path of the rotating member 13.
As shown in fig. 10, taking three receiving slots 132 as an example, two sets of receiving slots 132 are disposed adjacently, wherein the distance between the receiving slots 132 disposed adjacently in one set is the same as the distance between the first opening 181 and the atomizing area 183 along the rotation path of the rotating member 13, and the distance between the receiving slots 132 disposed adjacently in the other set is the same as the distance between the atomizing area 183 and the second opening 182 along the rotation path of the rotating member 13. In contrast to a solution with only one receiving slot 132, there is no need for the rotary member 13 to be rotated back and forth to deliver the next aerosol-generating article S. In the counterclockwise direction of fig. 10 to 11, the rotary member 13 can rotate all the time in the same direction, and after one of the receiving slots 132 moves to the atomizing area 183, the next receiving slot 132 rotates to the position of the first opening 181 to receive a new aerosol-generating article S; when the aerosol-generating article S in the region to be atomized 183 is fully consumed and rotates towards the second opening 182, the receptacle 132 receiving a new aerosol-generating article S is also rotated towards the atomization region 183 to atomize a new aerosol-generating article S, which is cycled. Therefore, the atomization efficiency can be effectively improved, and the energy utilization is larger.

A second drive element 20 is connected to the sealing cover 19 for driving the sealing cover 19 from the second position towards the first position. Of course, the sealing cover 19 can also be switched between the first position and the second position by manually actuating it. Wherein the driving force for the sealing cover 19 to move from the first position toward the second position can be provided by the rotational force of the rotary 13.
The second position can be any position spaced from the second opening 182 in a direction parallel to the bearing plate 18 or any position spaced from the second opening 182 in a direction perpendicular to the bearing plate 18. In one embodiment, the second position is directly above the second opening 182, and the sealing cover 19 moves along a direction perpendicular to the surface of the carrier plate 18 to be located at the first position or the second position.
