[0004] Currently, commonly used solid aerosol-generating substrates are usually packed in a columnar or granular form. Because the aerosol-generating substrate has low thermal conductivity and a large overall mass, it must absorb a large amount of heat during the heating process, resulting in problems such as long preheating times and slow heating rates.

[0027] 1 to 4, one embodiment of the present application provides a nebulization device 100, which includes a main housing 110, a mouthpiece 120, an aerosol-generating substrate cartridge 130, a power supply assembly 150, a drive assembly 180, a heating assembly 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 assembly 150, the heating assembly 170, the drive assembly 180, and the control unit are all attached within the main housing 110, and the aerosol-generating substrate cartridge 130 is detachably attached within the main housing 110, and an aerosol-generating substrate 132 and a transport mechanism (133, 134, 135) are housed within the aerosol-generating substrate cartridge 130.

[0028] Under the control of the control unit, the drive assembly 180 drives the transport mechanisms (133, 134, 135) in the aerosol-generating substrate cartridge 130 to release the aerosol-generating substrate 132, thereby moving the aerosol-generating substrate 132 along a predetermined path, and the heating assembly 170 is located in the path of movement of the aerosol-generating substrate 132. The released aerosol-generating substrate 132 is heated by electrical energy from the power supply assembly 150, and is atomized by the heat to generate an aerosol, which flows out through the mouthpiece 120 and is inhaled by the user.

[0029] The main housing 110 is 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 define a storage cavity 118 for storing a structure such as an aerosol-generating substrate cartridge 130. In the following embodiments, 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). Note 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.

[0030] The aerosol-generating substrate cartridge 130 is removably housed within the housing cavity 118 and includes a main cartridge body 131, an aerosol-generating substrate 132, and a transport mechanism (133, 134, 135). The strip- or sheet-shaped aerosol-generating substrate 132 is stored in the main cartridge body 131 by being wound, folded, stacked, or the like, and the transport mechanism (133, 134, 135) is controlled by driving the drive assembly 180 to release the aerosol-generating substrate 132 so that the heating element 174 sequentially heats different regions of the aerosol-generating substrate 132.

[0031] 2 to 5, main cartridge body 131 has a hollow cubic housing structure, with the length direction of main cartridge body 131 extending along a first direction, the width direction of main cartridge body 131 extending along a second direction, and the thickness direction of main cartridge body 131 extending along a third direction. Note that the shape of main cartridge body 131 is not limited to this, and the shape of main cartridge body 131 can be adapted to the shape of main housing 110 to meet different requirements.

[0032] The main cartridge body 131 is provided with a storage cavity 1312 and a recovery cavity 1314, which are independent of each other. The storage cavity 1312 stores unreleased aerosol-generating substrate 132, and the recovery cavity 1314 stores atomized aerosol-generating substrate 132. In this manner, the aerosol-generating substrate 132 in the storage cavity 1312 is gradually transported to the recovery cavity 1314 by the transport mechanism (133, 134, 135), and the heating element 174 can heat the aerosol-generating substrate 132 during transport.

[0033] Specifically, in one embodiment, the storage cavity 1312 and the collection cavity 1314 are spaced apart along the length of the main cartridge body 131 to reduce the width and thickness of the main cartridge body 131. 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 cartridge body 131. In other embodiments, the storage cavity 1312 and the collection cavity 1314 may be connected to each other to simplify the cartridge structure. In a preferred embodiment, to prevent the aerosol-generating substrate 132 in the storage cavity 1312 from becoming damp and deteriorating, a material or element having a drying function, such as a desiccant, may be placed in the storage cavity 1312 to absorb moisture from the air and ensure a dry internal environment of the storage cavity 1312.

[0034] To facilitate the heating element 174 heating the aerosol-generating substrate 132, a heating groove 1316 is provided at one end of the main cartridge body 131. 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 cartridge body 131 via the heating groove 1316. The heating groove 1316 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 is inserted into the heating groove 1316 in the third direction to heat the aerosol-generating substrate 132 located within the heating groove 1316. In addition, in order to prevent aerosols in the heating groove 1316 from entering the storage cavity 1312 and the recovery cavity 1314, the openings connecting both the storage cavity 1312 and the recovery cavity 1314 to the heating groove 1316 must be as small as possible, and a shielding structure such as a screen may be provided.

[0035] An atomizing seal member 160 is further provided within the main housing 110. The atomizing seal member 160 is provided at one end of the main cartridge body 131 where the heating groove 1316 is provided and covers the outside of the heating groove 1316, thereby defining an atomizing cavity that communicates between the heating groove 1316 and the mouthpiece 120. An air intake hole that communicates between the atomizing cavity and the external environment is formed in the atomizing seal member 160. In this way, external air flows into the atomizing cavity through the air intake hole, and the aerosol generated by atomization by the aerosol-generating substrate 132 can ride on the air flow and flow into the mouthpiece 120.

[0036] 5 and 8, the aerosol-generating substrate 132 is in a strip or sheet shape. Specifically, the strip-shaped aerosol-generating substrate 132 may be wound layer by layer in the circumferential direction to form a substrate roll and then housed in the main cartridge body 131, or may be folded back and forth in a linear direction to form a substrate pile and then housed in the main cartridge body 131. The sheet-shaped aerosol-generating substrate 132 may be stacked layer by layer in a linear direction to form a substrate pile and then housed in the main cartridge body 131. The storage method of the aerosol-generating substrate 132 is not limited, and different shapes can be formed by different winding and folding methods as needed.

[0037] The thickness of the aerosol-generating substrate 132 is preferably 0.1 mm to 0.8 mm, and the width is preferably 3 mm to 10 mm, and the heating element 174 can heat each portion of the aerosol-generating substrate 132 sequentially. Compared to conventional columnar aerosol-generating substrates, the sheet-shaped and strip-shaped aerosol-generating substrates 132 have a smaller thickness, which allows for a more uniform and rapid temperature rise during the heating process. Furthermore, the aerosol generated by the atomization of the aerosol-generating substrate 132 upon heating has a shorter escape path, eliminating the need for preheating. The thickness and width of the aerosol-generating substrate 132 are not limited to specific sizes and may be adjusted as needed to meet different requirements.

[0038] The aerosol-generating substrate 132 is made by mixing one or more of tobacco leaves, expanded tobacco stems, tobacco granules, tea leaves, and mint leaves with one or more of propylene glycol, glycerin, or other polyhydric alcohols as smoke generating agents, and materials such as flavorings, to form a slurry, so that it can generate an aerosol to be inhaled by humans through heated atomization. Note that the materials forming the aerosol-generating substrate 132 are not limited to these, and may be prepared as needed to meet different requirements.

[0039] In some embodiments, an electromagnetic heating unit is further uniformly arranged within the aerosol-generating substrate 132. The electromagnetic heating unit induces the magnetic field generated by the heating member 174 to generate an electric current, causing charges to move rapidly and irregularly thereon, which in turn generates thermal energy through collision friction to heat the aerosol-generating substrate 132. Specifically, the electromagnetic heating unit is made of one or more ferromagnetic materials, such as iron, cobalt, nickel and their alloys, and rare earth elements and their alloys, and the electromagnetic heating unit may be in one or more of the following forms: granular, powdery, fibrous, or flocculated form.

[0040] In some embodiments, the aerosol-generating substrate 132 includes at least one atomizing layer 1322 and at least one support layer 1323, where the atomizing layers 1322 and the support layers 1323 are alternately stacked along the thickness direction, and the support layer 1323 provides support for the atomizing layer 1322, improving the tensile and shear resistance capabilities of the aerosol-generating substrate 132. Here, an atomizing layer 1322 between two support layers 1323 is defined as one atomizing layer 1322.

[0041] 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. Note that the number of atomizing layers 1322 and support layers 1323 is not limited and may be provided as needed.

[0042] The support layer 1323 may be formed from 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, and alloy foils thereof, or from one or more of non-metallic heat-resistant tapes 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, or may be smaller or larger than, the width of the atomization layer 1322. In this way, the support layer 1323 has better mechanical properties than the atomization layer 1322, thereby improving the tensile resistance and shear resistance of the aerosol-generating substrate 132. The support layer 1323 can also transfer heat to preheat portions not in contact with the heating sheet, further improving heating uniformity.

[0043] Furthermore, the support layer 1323 is formed with communication holes 1323a penetrating along the thickness direction, and the plurality of communication holes 1323a are arranged in an array in at least a portion of the support layer 1323. The communication holes 1323a are configured to allow aerosol to flow from the atomization layer 1322 in which it is currently located to an adjacent atomization layer 1322 or to the outside. To ensure a sufficiently high escape rate of aerosol, the porosity of the support layer 1323 (i.e., the ratio of the total area of ​​the communication holes 1323a within a 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 communication holes 1323a formed 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 flow through the communicating holes 1323a formed in the support layer 1323 to the other atomization layer 1323.

[0044] 6 , in the first embodiment of the present application, the aerosol-generating substrate cartridge 130 includes a transport mechanism 133 that releases the aerosol-generating substrate 132, and the transport mechanism 133 includes a release center wheel 1332 and a transport assembly 1334. The release center wheel 1332 is rotatably attached to the storage cavity 1312, the central axis of the release center wheel 1332 extends along the third direction, and one end of the strip-shaped aerosol-generating substrate 132 is wound around the release center wheel 1332. The conveying assembly 1334 is located between the storage cavity 1312 and the recovery cavity 1314, and is located on the side of the heating groove 1316 adjacent to the recovery cavity 1314, and the conveying assembly 1334 applies a pulling force to one end of the aerosol-generating substrate 132 so that different regions of the aerosol-generating substrate 132 enter the heating groove 1316 sequentially, and drives and rotates the release center wheel 1332 to synchronously release the aerosol-generating substrate 132.

[0045] Specifically, the transport assembly 1334 includes two spaced apart transport rollers 1334a, which are rotatably mounted on the main cartridge body 131, with central axes of the two transport rollers 1334a extending along the third direction. A clamping gap is defined between the two transport rollers 1334a through which the aerosol-generating substrate 132 passes. The drive assembly 180 is operably connected to one of the transport rollers 1334a to drive and rotate the transport roller 1334a, so that the aerosol-generating substrate 132 positioned within the clamping gap is constantly advanced by the rotation of the transport roller 1334a, and passes through the heating groove 1316 and enters the collection cavity 1314.

[0046] 5 , in the second embodiment of the present application, the aerosol-generating substrate cartridge 130 includes a transport mechanism 134 that releases the aerosol-generating substrate 132. The transport mechanism 134 includes a release center wheel 1341 and a transport assembly, and the transport assembly includes a collection center wheel 1343. The release center wheel 1341 is rotatably attached to the storage cavity 1312, and the center axis of the release center wheel 1341 extends along the third direction. The collection center wheel 1343 is rotatably attached to the collection cavity 1314, and the center axis of the collection center wheel 1343 extends along the third direction. The front and rear ends of the aerosol-generating substrate 132 are wrapped around the release center wheel 1341 and the collection center wheel 1343, respectively. The drive assembly 180 is operatively connected to the collection center wheel 1343, which rotates when driven by the drive assembly 180 to collect the aerosol-generating substrate 132, and the aerosol-generating substrate 132, moved when driven by the collection center wheel 1343, drives the release center wheel 1341 to rotate synchronously, thereby releasing the aerosol-generating substrate 132 synchronously. Furthermore, in some embodiments, the conveying assembly further includes a plurality of intermediate pulleys, each of which is provided at a different position within the main cartridge body 131 so as to restrict the movement path of the aerosol-generating substrate 132.

[0047] 7 and 8 , in a third embodiment of the present application, the aerosol-generating substrate 132 is in the form of a sheet or a strip folded back and forth along one direction, and the aerosol-generating substrate cartridge 130 includes a transport mechanism 135 that releases the aerosol-generating substrate 132. The transport mechanism 135 includes a feed pickup roller 1352 and a feed roller assembly 1354. The feed pickup roller 1352 and the feed roller assembly 1354 are spaced apart on opposite sides of the heating groove 1316 in the second direction, and the feed pickup roller 1352 is located above the storage cavity 1312, with the central axis of the feed pickup roller 1352 extending along the third direction. The feed roller assembly 1354 includes two feed rollers 1354a spaced apart in the first direction, with the central axes of the feed rollers 1354a extending along the third direction, forming a feed gap between the two feed rollers 1354a. The drive assembly 180 is operatively connected to the feed pick-up roller 1352 and one of the feed rollers 1354a, and drives the feed pick-up roller 1352 and the feed roller 1354a to rotate, respectively.

[0048] In this way, the feeding and pick-up roller 1352 applies a forward force to the aerosol-generating substrate 132 by being driven by the drive assembly 180, and one end of the aerosol-generating substrate 132 is released by the pushing of the feeding and pick-up roller 1352 and enters the heating groove 1316, then enters the feed gap formed by the feed roller assembly 1354, and moves to the collection cavity 1314 by the rotation of the feed roller 1354a.

[0049] Furthermore, in the third embodiment, the aerosol-generating substrate cartridge 130 further includes a lifting mechanism 136 that pushes the aerosol-generating substrate 132 closer to the feed pick-up roller 1352, thereby bringing each sheet or segment of the aerosol-generating substrate 132 into contact with the feed pick-up roller 1352 in sequence, and entering the heating groove 1316 as the feed pick-up roller 1352 pushes it.

[0050] Specifically, the lifting mechanism 136 is located within the storage cavity 1312 and includes a lifting base 1361 and a lifting drive member 1363. The aerosol-generating substrate cartridge 130 carries the aerosol-generating substrate 132. The lifting drive member 1363 drives the lifting base 1361 to move along the first direction, thereby causing the aerosol-generating substrate 132 to always abut against the feeding and pick-up roller 1352. In a preferred embodiment, the lifting drive member 1363 is an elastic member that extends along the first direction and can apply a tensile force to the lifting base 1361 toward the feeding and pick-up roller 1352. Note that 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.

[0051] In some embodiments, the aerosol-generating substrate cartridge 130 further includes a crushing mechanism (not shown), which is provided within the collection cavity 1314 and applies a force to the aerosol-generating substrate 132 that has entered the collection cavity 1314, thereby crushing the released aerosol-generating substrate 132. The specific structure of the crushing mechanism is not limited as long as it is capable of crushing the aerosol-generating substrate 132. In other embodiments, the collection cavity 1314 may further include a pressing structure that presses the collected aerosol-generating substrate 132, which reduces space occupation and the volume of the collection cavity 1314, ultimately contributing to a smaller volume of the nebulization device 100.

[0052] 2 to 5, in some embodiments, a mounting post 1141 communicating with the atomization cavity is provided on the surface of the main housing 110 away from the accommodating cavity 118, and one end of the pillar-shaped mouthpiece 120 is inserted into the mounting post 1141, and the other end extends in the third direction away from the top wall 116 of the housing. In this way, the aerosol generated from the aerosol-generating substrate 132 in the aerosol-generating substrate cartridge 130 can flow out through the mouthpiece 120.

[0053] The power supply assembly 150 is located on one side of the mounting cavity in the second direction, and the heating assembly 170 is located on one side of the power supply assembly 150 in the first direction, and the heating assembly 170 includes a heating mounting housing 172 and a heating element 174. The heating mounting housing 172 is attached to the main cartridge body 131, and the heating element 174 has one end positioned within the main cartridge body 131 and electrically connected to the power supply assembly 150, and the other end inserted into the heating groove 1316 along the third direction to heat the aerosol-generating substrate 132.

[0054] Specifically, the heating element 174 can heat the aerosol-generating substrate 132 by conductive heating, infrared heating, electromagnetic heating, plasma heating, etc. Specifically, in some embodiments, the heating element 174 heats the aerosol-generating substrate 132 by conductive heating, and the heating element 174 is a flat heating sheet, an arc-shaped heating sheet, or a heating block that can generate heat after being energized, and the heating element 174 is inserted into the heating groove 1316 and comes into direct contact with the aerosol-generating substrate 132 to heat the aerosol-generating substrate 132 by conductive heating.

[0055] In another embodiment, 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, and when energized, generates an alternating magnetic field that excites the aerosol-generating substrate 132 to generate an alternating current, resulting in exothermic atomization. Preferably, the distance between the heating element 174 and the aerosol-generating substrate 132 is 0.5 mm to 2.0 mm.

[0056] The drive assembly 180 is located on one side of the power supply assembly 150 in the second direction of the mounting cavity, and the drive assembly 180 includes a drive motor that is operatively connected to the conveying mechanisms (133, 134, 135) to drive the conveying mechanisms (133, 134, 135) to release and collect the aerosol-generating substrate 132.

[0057] In some embodiments, the nebulization device 100 further includes a delivery detection assembly 190 communicatively connected to the control unit, which obtains the release length of the aerosol-generating substrate 132 to control the operating state of the drive assembly 180, and causes the transport mechanisms (133, 134, 135) to periodically release the aerosol-generating substrate 132. That is, the control unit controls the transport mechanisms (133, 134, 135) to release the aerosol-generating substrate 132 in a timely and quantitative manner, thereby renewing the aerosol-generating substrate 132 in the heating groove 1316 in a timely manner, ensuring maximum energy utilization, and avoiding excessive heating of the aerosol-generating substrate 132. Preferably, the release length of each cycle is equal to or greater than the length of the heating groove 1316 to avoid repeated heating of the 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 cartridge body 131 of the aerosol-generating substrate cartridge 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 delivery detection assembly 190 includes a detection rotating shaft 192, a presser wheel 194, and a detection unit 198. The detection rotating shaft 192 is inserted into the detection groove 1318 in the third direction and comes into close contact with one side surface of the aerosol-generating substrate 132. The detection rotating shaft 192 can rotate in conjunction with the moving aerosol-generating substrate 132. The pressure wheel 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 so as to bring the aerosol-generating substrate 132 into close contact with the detection rotation shaft 192. The feed detection unit 198 is connected to the detection rotation shaft 192 and located outside the main cartridge body 131. The feed detection unit 198 detects the rotation angle of the detection rotation shaft 192 to obtain the release length of the aerosol-generating substrate 132, and further feeds back a control signal to the drive assembly 180 to control the operating state of the drive assembly 180.

[0059] Furthermore, the detection assembly further includes a pressure wheel holder 196, one end of which is attached to the pressure wheel 194 and the other end of which is attached to the outside of the main housing 110, and the user can easily replace the aerosol-generating substrate cartridge 130 or the aerosol-generating substrate 132 by pushing the pressure wheel holder 196 along a first direction to adjust the gap between the pressure wheel 194 and the detection rotation axis 192.

[0060] Note that the detection method of the delivery detection assembly 190 is not limited thereto, and in some other embodiments, the delivery detection assembly 190 can control the operating state of the drive assembly 180 by detecting the rotation speed of the drive motor of the drive assembly 180. In other embodiments, the aerosol-generating substrate 132 is provided with detection marks spaced apart along its length, and the detection marks are formed by mechanical structural features, optical features, or magnetic features, and the delivery detection assembly 190 can detect the number of detection marks to obtain the release 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 can be formed on opposite sides of the support layer 1323 in the width direction at intervals along its length, and the number of metering holes passing through the delivery detection assembly 190 can be detected to obtain the release length of the aerosol-generating substrate 132.

[0061] In some embodiments, the nebulization device 100 further includes a remaining amount detection unit 198 communicatively connected to the control unit, which detects the remaining amount of the unreleased portion of the aerosol-generating substrate 132 and prompts the user to inspect and replace the aerosol-generating substrate cartridge 130 or the aerosol-generating substrate 132 in a timely manner. Specifically, the remaining amount detection unit 198 detects a change in the lock current of the motor of the drive assembly 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 this information back to the control unit, thereby outputting a signal, including but not limited to a display, vibration, and sound, to prompt the user to inspect and replace the aerosol-generating substrate cartridge 130.

[0062] In some embodiments, the nebulization device 100 further includes a sensor communicatively connected to the control unit, which acquires the number of puffs and the usage time, and presents the usage status of the nebulization device 100 to the user.

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

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

[0065] The technical features of the above-described embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features of the above-described embodiments are described, but all such combinations should be considered to fall within the scope described in this specification.

It should be noted that those skilled in the art can make some modifications or improvements without departing from the concept of the present application, and both of these modifications and improvements belong to the scope of protection of the present application.
