[0026] 1 to 4, one embodiment of the present application provides an atomization device 100, which includes a main housing 110, a mouthpiece 120, an aerosol-generation substrate box 130, a power supply module 150, a driving module 180, a heating module 170, and a control unit. The mouthpiece 120 is attached to one end of the main housing 110 and extends from the main housing 110. The power supply module 150, the heating module 170, the driving module 180, and the control unit are all attached within the main housing 110. The aerosol-generation substrate box 130 is detachably attached within the main housing 110, and an aerosol-generation substrate 132 and a transmission mechanism (133 / 134 / 135) are housed within the aerosol-generation substrate box 130.

[0027] Under the control of the control unit, the driving module 180 drives the transmission mechanisms (133 / 134 / 135) in the aerosol-generating substrate box 130 to release the aerosol-generating substrate 132, thereby moving the aerosol-generating substrate 132 along a predetermined path, and the heating module 170 is located on the path of the aerosol-generating substrate 132. The released aerosol-generating substrate 132 is heated by the action of electrical energy from the power supply module 150, and the aerosol-generating substrate 132 is atomized by the heat to form an aerosol, which flows out through the mouthpiece 120 and is inhaled by the user.

[0028] The main housing 110 has a hollow cubic housing structure and includes a housing bottom wall 112, housing side walls 114 extending in the same direction from the edges of the housing bottom wall 112, and a housing top wall 116 provided on the side of the housing side walls 114 away from the housing bottom wall 112. The housing bottom wall 112, the housing side walls 114, and the housing top wall 116 together form a storage cavity 118 for storing components such as the aerosol-generating substrate box 130. In the following embodiment, the length direction of the main housing 110 is the first direction (i.e., the X direction in FIG. 2 ), the width direction of the main housing 110 is the second direction (i.e., the Y direction in FIG. 2 ), and the thickness direction of the main housing 110 is the third direction (i.e., the Z direction in FIG. 2 ). It should be understood that the shape of the main housing 110 is not limited thereto, and in some other embodiments, the main housing 110 may have different shapes, such as a columnar shape or a tower shape, to meet different requirements.

[0029] The aerosol-generating substrate box 130 is removably housed in the storage cavity 118 and includes a main housing 131, an aerosol-generating substrate 132, and a transmission mechanism (133 / 134 / 135). The strip-shaped or sheet-shaped aerosol-generating substrate 132 is stored in the main housing 131 in a wrapped, folded, or stacked form, and the transmission mechanism (133 / 134 / 135) is controlled by a driving module 180 to release the aerosol-generating substrate 132 and cause the heating element 174 to heat different areas of the aerosol-generating substrate 132 in sequence.

[0030] 2 to 5, the main housing 131 has a hollow cubic housing structure, and the length direction of the main housing 131 extends along a first direction, the width direction of the main housing 131 extends along a second direction, and the thickness direction of the main housing 131 extends along a third direction. It can be understood that the shape of the main housing 131 is not limited thereto, and the shape of the main housing 131 can be adapted to the shape of the main housing 110 to meet different requirements.

[0031] The main housing 131 is provided with a storage cavity 1312 and a recovery cavity 1314, which are independent of each other. The storage cavity 1312 stores the unreleased aerosol-generating substrate 132, and the recovery cavity 1314 stores the atomized aerosol-generating substrate 132. In this manner, the aerosol-generating substrate 132 in the storage cavity 1312 is gradually transferred to the recovery cavity 1314 by the transfer mechanism (133 / 134 / 135), and the heating element 174 can heat the aerosol-generating substrate 132 during the transfer process.

[0032] Specifically, in one embodiment, the storage cavity 1312 and the collection cavity 1314 are spaced apart along the length of the main housing 131, thereby reducing the width and thickness of the main housing 131. As can be appreciated, the relative positions of the storage cavity 1312 and the collection cavity 1314 are not limited, and in some other embodiments, the storage cavity 1312 and the collection cavity 1314 may be spaced apart along the width of the main housing 131. In other embodiments, the storage cavity 1312 and the collection cavity 1314 are in communication with each other, thereby simplifying the housing structure. In a preferred embodiment, to prevent the aerosol-generating substrate 132 in the storage cavity 1312 from being deteriorated by moisture, a material or element having a drying function, such as a desiccant, is placed in the storage cavity 1312 to absorb moisture from the air and ensure a dry internal environment of the storage cavity 1312.

[0033] To facilitate heating of the aerosol-generating substrate 132 by the heating element 174, a heating groove 1316 is provided at one end of the main housing 131, and the storage cavity 1312 and the collection cavity 1314 are located on opposite sides of the heating groove 1316 in the second direction, and the storage cavity 1312 and the collection cavity 1314 are connected to the external environment of the main housing 131 by the heating groove 1316, which is located in the path of movement of the aerosol-generating substrate 132. In this manner, the aerosol-generating substrate 132 released from the storage cavity 1312 passes through the heating groove 1316 and enters the collection cavity 1314, and one end of the heating element 174 enters the heating groove 1316 in the third direction to heat the aerosol-generating substrate 132 located within the heating groove 1316. As can be understood, both the storage cavity 1312 and the recovery cavity 1314 may have openings communicating with the heating groove 1316 as small as possible, and a shielding structure such as a curtain may be provided to prevent aerosols in the heating groove 1316 from entering the storage cavity 1312 and the recovery cavity 1314.

[0034] Furthermore, an atomizing sealing member 160 is provided within the main housing 110. The atomizing sealing member 160 is disposed and connected to one end of the main casing 131 where the heating groove 1316 is provided, and covers the outside of the heating groove 1316, thereby defining and forming an atomizing cavity that communicates between the heating groove 1316 and the mouthpiece 120. An air intake hole is provided in the atomizing sealing member 160 to communicate between the atomizing cavity and the external environment. In this way, external air flows into the atomizing cavity through the air intake hole, and the aerosol generated by atomizing the aerosol-generating substrate 132 can flow into the mouthpiece 120 along with the airflow.

[0035] 5 and 8, the aerosol-generating substrate 132 has a strip or sheet shape. Specifically, the strip-shaped aerosol-generating substrate 132 may be wound layer by layer along the circumferential direction to form a substrate roll and stored in the main housing 131, or may be folded back and forth along a linear direction to form a substrate bundle and stored in the main housing 131. The sheet-shaped aerosol-generating substrate 132 may be stacked layer by layer along a linear direction to form a substrate bundle and stored in the main housing 131. As can be understood, the storage form of the aerosol-generating substrate 132 is not limited, and different shapes may be formed by different winding and folding forms as needed.

[0036] The aerosol-generating substrate 132 preferably has a thickness of 0.1 mm to 0.8 mm and a width of 3 mm to 10 mm, and the heating element 174 can heat each portion of the aerosol-generating substrate 132 sequentially. Compared with the conventional cylindrical aerosol-generating substrates, the thickness of the sheet-shaped and strip-shaped aerosol-generating substrates 132 is extremely small. Therefore, during the heating process, the temperature rise is uniform and rapid. The aerosol generated by the aerosol-generating substrate 132 being atomized by heat has a short overflow path, and preheating is not required. It should be understood that the thickness and width of the aerosol-generating substrate 132 are not limited to specific dimensions and may be set as needed to meet different requirements.

[0037] The aerosol-generating substrate 132 may be prepared by mixing one or more of tobacco leaves, expanded tobacco stems, tobacco particles, tea leaves, and mint leaves with one or more of the smoke-generating agents propylene glycol, glycerin, or other polyols, and ingredients such as essential flavorings to form a slurry, which can be atomized by heating to generate an inhalable aerosol. As can be appreciated, the materials for forming the aerosol-generating substrate 132 are not limited to these and may be configured as needed to meet different requirements.

[0038] In some embodiments, electromagnetic heating units are further uniformly distributed within the aerosol-generating substrate 132, and the electromagnetic heating units can generate electric currents induced by the magnetic field generated by the heating members 174, causing charges thereon to move irregularly at high speed, colliding and rubbing together to generate thermal energy and heat the aerosol-generating substrate 132. Specifically, the electromagnetic heating units are made of ferromagnetic materials, such as one or more of iron, cobalt, nickel and their alloys, and rare earth elements and their alloys, and the electromagnetic heating units may take one or more of the following forms: particles, powder, fibers, or fluff.

[0039] In some embodiments, the aerosol-generating substrate 132 includes at least one atomizing layer 1322 and at least one support layer 1323, the atomizing layers 1322 and the support layers 1323 being alternately stacked in the thickness direction, the support layer 1323 providing support to the atomizing layer 1322 and improving the tensile and shear resistance of the aerosol-generating substrate 132. An atomizing layer 1322 between two support layers 1323 is also defined as one atomizing layer 1322.

[0040] 9, specifically, in one embodiment, the aerosol-generating substrate 132 includes one atomizing layer 1322 and one support layer 1323, with the support layer 1323 located on the upper or lower surface of the atomizing layer 1322. Specifically, in another embodiment, the aerosol-generating substrate 132 includes two atomizing layers 1322 and one support layer 1323, with the support layer 1323 located between the two atomizing layers 1322. As can be understood, the number of atomizing layers 1322 and support layers 1323 is not limited and can be set as needed.

[0041] The support layer 1323 may be formed of one or more of metal materials, such as gold, silver, copper, iron, tin, zinc, nickel, aluminum, tungsten, molybdenum, tantalum, niobium, titanium, nickel-based, cobalt-based, steel, stainless steel metal, and alloy foils thereof, or may be formed of one or more of heat-resistant non-metallic membranes, such as glass fiber, Teflon, and polyimide. The thickness of the support layer 1323 is preferably 0.01 mm to 0.15 mm, and the width of the support layer 1323 may be equal to, smaller than, or larger than the width of the atomization layer 1322. The support layer 1323 has superior mechanical properties compared to the atomization layer 1322, thereby improving the tensile and shear resistance of the aerosol-generating substrate 132. Furthermore, the support layer 1323 is capable of transferring heat. This allows the portions not in contact with the heating sheet to be preheated, further improving the uniformity of heating.

[0042] Furthermore, the support layer 1323 has through-holes 1323a extending through it in the thickness direction. The through-holes 1323a are arranged in an array in at least a portion of the support layer 1323, and the through-holes 1323a allow the aerosol to flow from the atomization layer 1322 where it is currently located to an adjacent atomization layer 1322 or to the outside. To ensure a sufficiently high aerosol overflow rate, the porosity of the support layer 1323 (i.e., the ratio of the total area of ​​the through-holes 1323a per unit area to the unit area) is 30% or more. Specifically, when the aerosol-generating substrate 132 includes one atomization layer 1322 and one support layer 1323, the support layer 1323 is located on the upper or lower surface of the atomization layer 1322, and the aerosol generated by atomization of the atomization layer 1322 flows out through the through-holes 1323a opened in the support layer 1323. When the aerosol-generating substrate 132 includes two atomization layers 1322 and one support layer 1323, and the support layer 1323 is positioned between the two atomization layers 1322, the aerosol generated by atomization of one of the atomization layers 1322 can pass through the communication hole 1323a opened in the support layer 1323 and flow to the other atomization layer 1323.

[0043] Referring to FIG. 6, in the first embodiment of the present application, the aerosol-generating substrate box 130 includes a transmission mechanism 133 for discharging the aerosol-generating substrate 132, and the transmission mechanism 133 includes a discharge center roller. 1332 and a transmission module 1334. 1332 is pivotally mounted in the storage cavity 1312 and has a discharge center roller 1332 The central axis of the aerosol-generating substrate 132 extends along the third direction, and one end of the strip-shaped aerosol-generating substrate 132 is connected to a central discharge roller. 1332 The transmission module 1334 is located between the storage cavity 1312 and the collection cavity 1314, and is on the side of the heating groove 1316 that is adjacent to the collection cavity 1314. The transmission module 1334 applies a pulling force to one end of the aerosol-generating substrate 132, so that different regions of the aerosol-generating substrate 132 are sequentially inserted into the heating groove 1316 and the discharge center roller 1334 is wound around the aerosol-generating substrate 132. 1332are driven to rotate and release the aerosol-generating substrates 132 in a synchronized manner.

[0044] Specifically, the transmission module 1334 includes two transmission rollers 1334a spaced apart from each other, which are rotatably mounted on the main housing 131, with their central axes extending along the third direction. A clamping gap is defined between the two transmission rollers 1334a, through which the aerosol-generating substrate 132 passes. The driving module 180 is transmissively connected to one of the transmission rollers 1334a to drive and rotate the transmission roller 1334a. The aerosol-generating substrate 132 positioned within the clamping gap continues to move forward due to the rotation of the transmission roller 1334a, and enters the collection cavity 1314 via the heating groove 1316.

[0045] 5 , in a second embodiment of the present application, the aerosol-generating box includes a transmission mechanism 134 for discharging the aerosol-generating substrate 132. The transmission mechanism 134 includes a discharge central roller 1341 and a transmission module. The transmission module includes a collection central roller 1343. The discharge central roller 1341 is rotatably attached to the storage cavity 1312, and the central axis of the discharge central roller 1341 extends along the third direction. The collection central roller 1343 is rotatably attached to the collection cavity 1314, and the central axis of the collection central roller 1343 extends along the third direction. The front and rear ends of the aerosol-generating substrate 132 are wound around the discharge central roller 1341 and the collection central roller 1343, respectively. The drive module 180 is transmissively connected to the collection center roller 1343, which is driven to rotate by the drive module 180 to collect the aerosol-generating substrate 132, and the aerosol-generating substrate 132, driven to move by the collection center roller 1343, rotates synchronously with the discharge center roller 1341, thereby synchronously discharging the aerosol-generating substrate 132. Furthermore, in some embodiments, the transmission module further includes a plurality of intermediate pulleys, each of which is provided at a different position within the main housing 131, to restrict the movement path of the aerosol-generating substrate 132.

[0046] 7 and 8 , in a third embodiment of the present application, the aerosol-generating substrate 132 has a sheet-like or strip-like structure folded back and forth along one direction, and the aerosol-generating substrate box 130 includes a transmission mechanism 135 for releasing the aerosol-generating substrate 132. The transmission mechanism 135 includes a feeding pickup roller 1352 and a transport roller module 1354. The feeding pickup roller 1352 and the transport roller module 1354 are spaced apart on opposite sides of the heating groove 1316 in the second direction, and the feeding pickup roller 1352 is located above the storage cavity 1312, with the central axis of the feeding pickup roller 1352 extending along the third direction. The transport roller module 1354 includes two transport rollers 1354a spaced apart in the first direction, with the central axes of the transport rollers 1354a extending along the third direction, and a transport gap is formed between the two transport rollers 1354a. The driving module 180 is transmissively connected to the feeding pickup roller 1352 and one of the conveying rollers 1354a, thereby driving the feeding pickup roller 1352 and the conveying roller 1354a to rotate, respectively.

[0047] In this way, the feeding pickup roller 1352, driven by the drive module 180, applies a forward force to the aerosol-generating substrate 132, and one end of the aerosol-generating substrate 132 is pushed out by the feeding pickup roller 1352 and enters the heating groove 1316, then enters the conveying gap formed by the conveying roller module 1354, and moves to the collection cavity 1314 by the rotation action of the conveying roller 1354a.

[0048] Furthermore, in the third embodiment, the aerosol-generating substrate box 130 further includes a lifting mechanism 136 which pushes the aerosol-generating substrate 132 closer to the feeding pickup roller 1352, thereby bringing each sheet or each row of the aerosol-generating substrate 132 into contact with the feeding pickup roller 1352 in sequence, and further pushing the aerosol-generating substrate 132 into the heating groove 1316 by the feeding pickup roller 1352.

[0049] Specifically, the lifting mechanism 136 is located in the storage cavity 1312 and includes a lifting base 1361 and a lifting drive member 1363. The aerosol-generating substrate 132 is placed on the lifting base 1361. The lifting drive member 1363 moves the lifting base 1361 in the first direction, thereby keeping the aerosol-generating substrate 132 in constant contact with the feeding pickup roller 1352. In a preferred embodiment, the lifting drive member 1363 is an elastic member extending in the first direction, and can apply a tensile force to the lifting base 1361 toward the feeding pickup roller 1352. As can be understood, the specific structure of the lifting drive member 1363 is not limited, and in some other embodiments, the lifting drive member 1363 may be a driving structure such as a screw.

[0050] In some embodiments, the aerosol-generating substrate box 130 further includes a crushing mechanism (not shown), which is provided in the collection cavity 1314 and applies a force to the aerosol-generating substrate 132 entering the collection cavity 1314 to crush the released aerosol-generating substrate 132. As can be understood, the specific structure of the crushing mechanism is not limited as long as it can crush the aerosol-generating substrate 132. In other embodiments, a pressing structure may be provided in the collection cavity 1314 to compress the collected aerosol-generating substrate 132, thereby reducing its space occupation and reducing the volume of the collection cavity 1314, ultimately advantageously reducing the volume of the nebulization device 100.

[0051] 2 to 5, in some embodiments, a mounting post 1141 communicating with the atomization cavity is protruded from the surface of the main housing 110 facing away from the storage cavity 118, and one end of the pillar-shaped mouthpiece 120 is inserted into the mounting post 1141, while the other end of the mouthpiece 120 extends in the third direction away from the housing top wall 116. In this way, the aerosol generated by the aerosol-generating substrate 132 in the aerosol-generating substrate box 130 can flow out through the mouthpiece 120.

[0052] The power supply module 150 is located on a side of the mounting cavity in the second direction, and the heating module 170 is located on a side of the power supply module 150 in the first direction, and the heating module 170 includes a heating mounting case 172 and a heating element 174. The heating mounting case 172 is disposed and connected to the main housing 131, one end of the heating element 174 is positioned within the main housing 131 and electrically connected to the power supply module 150, and the other end of the heating element 174 extends into the heating groove 1316 along the third direction to heat the aerosol-generating substrate 132.

[0053] Specifically, in some embodiments, the heating element 174 is configured as a resistance heater, an electromagnetic induction heater, or a plasma heater, and is in close contact with the aerosol-generating substrate to conduct heat to the aerosol-generating substrate. Specifically, in some embodiments, the heating element 174 heats the aerosol-generating substrate 132 by conductive heating, and is a flat heating sheet, an arc-shaped heating sheet, or a heating block that can generate heat after being energized. The heating element 174 fits into the heating groove 1316 and directly contacts the aerosol-generating substrate 132 to heat the aerosol-generating substrate 132 by conductive heating.

[0054] In some other embodiments, an electromagnetic heating unit is disposed within the aerosol-generating substrate 132, and the heating element 174 is an electromagnetic heating coil. The heating element 174 is inserted into the heating groove 1316 and spaced apart from the aerosol-generating substrate 132. When energized, the heating element 174 generates an alternating magnetic field, which excites the aerosol-generating substrate 132 to generate an alternating current, which generates heat and atomizes the aerosol-generating substrate 132. Preferably, the distance between the heating element 174 and the aerosol-generating substrate 132 is 0.5 mm to 2.0 mm.

[0055] In some other embodiments, the heating module 170 is configured as a microwave heating device or an infrared radiant heating device, and the heating module 170 is in close proximity to the aerosol-generating substrate to transmit microwave or infrared radiation to the aerosol-generating substrate.

[0056] The drive module 180 is located on the second side of the mounting cavity of the power supply module 150, and includes a drive motor that is transmissively connected to the transmission mechanism (133 / 134 / 135) to drive the transmission mechanism (133 / 134 / 135) to emit and collect the aerosol generating substrate 132.

[0057] In some embodiments, the atomization device 100 further includes a feed detection module 190 communicatively connected to the control unit. The feed detection module 190 acquires the ejection length of the aerosol-generating substrate 132 to control the operating state of the drive module 180 and cause the transmission mechanism (133 / 134 / 135) to periodically eject the aerosol-generating substrate 132. That is, the control unit controls the transmission mechanism (133 / 134 / 135) to eject the aerosol-generating substrate 132 at a predetermined timing and in a predetermined amount, thereby timely updating the aerosol-generating substrate 132 in the heating channel 1316, ensuring maximum energy utilization and avoiding excessive heating of the aerosol-generating substrate 132. Preferably, the ejection length of each cycle is equal to or greater than the length of the heating channel 1316, thereby avoiding repeated heating of an already heated portion.

[0058] Specifically, a detection groove 1318 communicating with the storage cavity 1312 and the heating groove 1316 is formed at one end of the main housing 131 of the aerosol-generating substrate box 130, where the heating groove 1316 is provided. The aerosol-generating substrate 132 released from the storage cavity 1312 is detected by the detection groove 1318 and then enters the heating groove 1316 to be heated. The feeding detection module 190 includes a detection rotating shaft 192, a pinch roller 194, and a detection unit 198. The detection rotating shaft 192 enters the detection groove 1318 in the third direction and is in close contact with one surface of the aerosol-generating substrate 132. The detection rotating shaft 192 can rotate along with the moving aerosol-generating substrate 132. The pinch roller 194 is located on one side of the detection rotation shaft 192 in the first direction, and applies pressure to the aerosol-generating substrate 132 to ensure that the aerosol-generating substrate 132 is tightly attached to the detection rotation shaft 192. The feed detection unit 198 is connected to the detection rotation shaft 192 and located outside the main housing 131, and detects the rotation angle of the rotation shaft 192 to obtain the ejection length of the aerosol-generating substrate 132, and further feeds back a control signal to the driving module 180 to control the operating state of the driving module 180.

[0059] Furthermore, the detection module further includes a pinch roller holder 196, one end of which is arranged and connected to the pinch roller 194, and the other end of which is arranged and connected outside the main housing 110, so that the user can conveniently replace the aerosol generation box or the aerosol generation substrate 132 by pushing the pinch roller holder 196 along the first direction to adjust the gap between the pinch roller 194 and the detection rotation axis 192.

[0060] As can be understood, the detection method of the feeding detection module 190 is not limited to this, and in some other embodiments, the feeding detection module 190 can control the operating state of the drive module 180 by detecting the rotation speed of the drive motor of the drive module 180. In other embodiments, detection marks are provided at intervals along the length of the aerosol-generating substrate 132, and the detection marks are formed by mechanical structural features, optical features, or magnetic features, and the feeding detection module 190 can detect the number of detection marks to obtain the emission length of the aerosol-generating substrate 132. Specifically, in one embodiment, if the aerosol-generating substrate 132 is provided with a support layer 1323, metering holes are formed on opposite sides of the support layer 1323 in the width direction, spaced apart along the length of the support layer 1323, and the emission length of the aerosol-generating substrate 132 can be obtained by detecting the number of metering holes passing through the feeding detection module 190.

[0061] In some embodiments, the nebulization device 100 further includes a remaining amount detection unit 198 communicatively connected to the control unit. The remaining amount detection unit 198 detects the remaining amount of the unreleased aerosol-generating substrate 132, thereby prompting a user to inspect or replace the aerosol-generating substrate box 130 or the aerosol-generating substrate 132 in a timely manner. Specifically, the remaining amount detection unit 198 detects a change in the jamming current of the motor of the driving module 180 or a change in the temperature curve of the heating element 174 to obtain the remaining amount of the aerosol-generating substrate 132 in the storage cavity 1312, and feeds the information back to the control unit, thereby outputting, including but not limited to, a display, vibration, and sound, to prompt a user to inspect or replace the aerosol-generating substrate box 130.

[0062] In some embodiments, the nebulization device 100 is further provided with a sensor communicatively connected to the control unit, and the sensor is configured to obtain the number of inhalations and the usage time to provide the user with information on the usage status of the nebulization device 100.

[0063] In some embodiments, the main housing 110 is provided with an attachment detection unit 198, and the aerosol-generating substrate box 130 is provided with a sensing element 137 corresponding to the attachment detection unit 198. The attachment detection unit 198 can detect the sensing element 137 to determine whether the aerosol-generating substrate box 130 is present in the attachment cavity. Specifically, the attachment detection unit 198 can include, but is not limited to, a Hall sensor or a photoelectric sensor. The sensing element 137 can include, but is not limited to, a magnetic element corresponding to the Hall sensor or a light shielding plate corresponding to the photoelectric sensor. The Hall sensor can determine whether the aerosol-generating substrate box 130 is present in the attachment cavity by detecting whether a magnetic element is present. The photoelectric sensor can determine whether the aerosol-generating substrate box 130 is present in the attachment cavity by detecting whether a light shielding plate is present.

[0064] In the atomization device 100, different regions of the strip-shaped or sheet-shaped aerosol-generating substrate 132 are heated sequentially by the heating element 174. Since the thickness of the aerosol-generating substrate 132 is thin each time it is heated, the temperature rise rate is fast, the aerosol overflow time is short, and different regions of the aerosol-generating substrate 132 can be heated uniformly, thereby achieving high energy utilization rate and high consistency in texture.

[0065] The technical features of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described. However, combinations of these technical features should be considered to be within the scope of the present specification unless there is a contradiction.

[0066] The above examples merely illustrate some embodiments of the present application, and although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the claims. Those skilled in the art can make various modifications and improvements without departing from the concept of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application is subject to the scope of the accompanying claims. [Explanation of symbols]
