[0032] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0033] The present invention constructs an aerosol generating device, which can use microwaves to heat an aerosol generating article 200 (see Figure 1 ), to generate aerosol by atomization, so as to be inhaled or inhaled by the user. In some embodiments, the aerosol generating product 200 is a solid aerosol generating product 200 such as a processed plant leaf product. It can be understood that in other embodiments, the aerosol generating product 200 can also be a liquid aerosol generating product 200.

[0034] See also Figure 1 The aerosol generating device may include a microwave generating assembly (not shown) and a microwave heating assembly 1. The microwave generating assembly is used to generate microwaves; the microwave heating assembly 1 is connected to the microwave generating assembly to receive microwaves, and a microwave field is formed in its cavity 113 to act on the aerosol generating product 200, thereby achieving microwave heating.

[0035] like Figure 1 As shown, the overall shape of the microwave heating component 1 is roughly cylindrical in some embodiments. Of course, the microwave heating component 1 is not limited to a cylindrical shape, and it can also be in other shapes such as a square column, an elliptical column, etc.

[0036] See also Figure 2 The microwave heating assembly 1 may include an outer conductor unit 11 , an inner conductor unit 12 , a receiving seat 13 and a microwave feeding unit 14 .

[0037] The outer conductor unit 11 has a closed end 111 and an open end 112 opposite to the closed end 111, and can define a semi-closed cavity 113, and the inner wall surface of the cavity 113 can be conductive. The inner conductor unit 12 includes a microwave matching structure 121 and a microwave radiating structure 122 combined with the microwave matching structure 121. The bottom of the microwave matching structure 121 is connected to the closed end 111 of the outer conductor unit 11, and is in ohmic contact with the end wall of the closed end 111, forming the short-circuit end of the microwave heating component 1. One end of the microwave radiating structure 122 is combined with the top of the microwave matching structure 121, and the other end of the microwave radiating structure 122 is located in the cavity 113, but is not in direct contact with the outer conductor unit 11, forming the open-circuit end of the microwave heating component 1. The microwave feeding unit 14 is detachably mounted on the outer conductor unit 11, and is used to feed the microwave generated by the microwave generating assembly into the cavity 113. The receiving seat 13 is fixedly or detachably installed at the open end 112 of the outer conductor unit 11 , defining a receiving cavity 130 for receiving the aerosol generating product 200 . One end of the microwave radiation structure 122 away from the microwave matching structure 121 extends and is inserted into the receiving cavity 130 .

[0038] Understandably, the aerosol generating product 200 can be partially / entirely inserted into the receiving cavity 130, and in this case, part of the structure of the microwave radiation structure 122 is inserted into the interior of the aerosol generating product 200. When the microwave generating component feeds microwaves to the microwave heating component 1 through the microwave feeding unit 14, a microwave energy field can be formed around the microwave radiation structure 122 to heat the interior of the aerosol generating product 200. In conjunction with the inhalation action of the smoker, the airflow is driven, and the aerosol formed by mixing the air and the medium generated after heating can enter the mouth of the smoker along the direction of the airflow.

[0039] The structures of the various components of the microwave heating assembly 1 in some embodiments are described in detail below.

[0040] In some embodiments, the outer conductor unit 11 can be made of a conductive metal material, preferably aluminum alloy or copper. It is understandable that the outer conductor unit 11 is not limited to being made of a conductive material, and can also be achieved by coating the inner wall of the non-conductive cylinder with a conductive coating. Optionally, the conductive coating is a silver coating or a gold coating.

[0041] See also Figure 3In some embodiments, the outer conductor unit 11 may include a conductive conductor side wall 114 and a conductor end wall 115. The conductor side wall 114 may be cylindrical, including opposite, open top and bottom ends, and the conductor end wall 115 is sealed on the bottom end of the conductor side wall 114 to form the above-mentioned closed end 111; the top end of the conductor side wall 114 forms the above-mentioned open end 112. The conductor side wall 114 and the conductor end wall 115 together form the above-mentioned cavity 113, which is cylindrical.

[0042] In addition, the conductor side wall 114 is provided with a feeding hole 116 radially penetrating the conductor side wall 114 near the conductor end wall 115, and the feeding hole 116 allows the microwave feeding unit 14 to be inserted into the inner part of the outer conductor unit 11. The aperture of the feeding hole 116 is adapted to the outer diameter of the outer conductor of the microwave feeding unit 14. An axially penetrating mounting hole is also provided at the center of the conductor end wall 115, and the mounting hole is used for the inner conductor unit 12 to be installed and fixed thereon.

[0043] See also Figure 3 In some embodiments, the receiving seat 13 is detachably mounted on one end of the conductor side wall 114 away from the conductor end wall 115, and the receiving seat 13 may include a receiving portion 132 and a fixing portion 133 integrally connected to the receiving portion 132. The receiving portion 132 is used to receive the aerosol generating product 200; the fixing portion 133 is used to axially block the end of the conductor side wall 114 away from the conductor end wall 115, and fix the receiving portion 132 in the cavity 113.

[0044] like Figure 3 As shown, the receiving portion 132 may be cylindrical, with an outer diameter smaller than the inner diameter of the outer conductor unit 11, installed in the cavity 113, and defining an axial receiving cavity 130 for receiving the aerosol generating product 200. Optionally, the top of the receiving portion 132 is open and provided with an opening 131, and the aerosol generating product 200 can extend into the receiving cavity 130 from the opening 131 at the top of the receiving portion 132; and the bottom of the receiving portion 132 is closed and has a bottom wall 1311 for supporting the aerosol generating product 200.

[0045] See also Figure 4 The bottom wall 1311 is circular. Of course, the shape of the bottom wall 1311 can also be square, trapezoidal or other shapes, which are not specifically limited here.

[0046] In some embodiments, the bottom wall 1311 is partially recessed to form an air guide groove 1313, which is used to successfully draw ambient air into the interior of the aerosol generating product 200, thereby avoiding the problem that there is no gap between the aerosol generating product 200 and the bottom wall 1311, resulting in the inability of air to flow into the interior of the aerosol generating product 200. The non-recessed portion of the bottom wall 1311 forms a supporting portion 1312, which is used to support the bottom of the aerosol generating product 200 when it is installed in the receiving portion 132.

[0047] Of course, in other embodiments, a supporting structure may be disposed on the bottom wall 1311 to form a supporting portion 1312 , and the side surface of the supporting structure and the bottom wall 1311 together define an air guide groove 1313 .

[0048] Secondly, in order to reduce the difficulty of cleaning the air guide groove 1313 and avoid the cleaning problems as those in the related art (for example, in the related art, the bottom wall 1311 is provided with a plurality of protruding support structures distributed at circumferential intervals, for supporting the aerosol generating product 200, wherein a single support structure is longitudinally elongated, and its length direction is the direction extending from the edge of the bottom wall 1311 to the center of the bottom wall 1311; the air guide groove 1313 is formed at the interval between every two support structures, and because the structure of the support structure is large and the number is large, the area distribution of the air guide groove 1313 is radial, and there are many cleaning dead corners, and condensate or medium residues are easily retained in these cleaning dead corners, and are difficult to clean.), the convenience of cleaning can be improved, refer to Figures 4 to 10 In the present invention, at least most of the supporting portion 1312 is disposed at the edge of the entire bottom wall 1311, and the air guide groove 1313 is formed at the inner periphery of the supporting portion 1312, and at least most of the area of ​​the air guide groove 1313 is smoothly concentrated together, such as concentrated at the inner position of the bottom wall 1311. The "most of the area" can be understood as an area proportion exceeding 50%, such as 60%, 70%, 80%, 90%, or even 100%.

[0049] Through the above-mentioned design, the receiving seat 13 supports the aerosol generating product 200 by relying on the edge peripheral position of the bottom wall 1311, avoiding using the internal position of the bottom wall 1311 for support, and avoiding the air guide groove 1313 being divided into small grooves by the supporting portion 1312; smooth, concentrated and relatively spacious grooves are formed on the bottom wall 1311, reducing corner positions that are prone to forming cleaning dead corners, and most or even the entire air guide groove 1313 can be cleaned during the cleaning process, effectively improving the convenience of cleaning.

[0050] The following examples illustrate some embodiments of the supporting portion 1312 and the air guide groove 1313 of the present invention. For example, in embodiment 1-1, Figure 4 As shown, the supporting portion 1312 extends continuously from the center of the bottom wall 1311 to the edge of the bottom wall 1311 , and continues to extend along the edge of the bottom wall 1311 in a major arc path.

[0051] The inner peripheral wall of the supporting portion 1312 defines an air guide groove 1313, and the shape of the air guide groove 1313 is a volute shape. Of course, the air guide groove 1313 can also be other shapes. The purpose of setting the volute shape is to make the air flow smoother. Among them, the notch formed by the supporting portion 1312 at the edge position of the bottom wall 1311 forms an air inlet 13131 of the air guide groove 1313, and the air from the external environment can enter the interior of the air guide groove 1313 from the air inlet 13131, and then flow vertically upward to the interior of the aerosol generating product 200. Most of the area of ​​the entire air guide groove 1313 is distributed in the internal position of the bottom wall 1311. A through-type through hole 1315 is also provided at the center position of the bottom wall 1311 for the microwave radiation structure 122 to be inserted into the receiving cavity 130. The supporting portion 1312 located at the center of the bottom wall 1311 plays the same role as the protrusion 1314 described below, which can ensure that there is no extra gap between the microwave radiation structure 122 when the microwave radiation structure 122 is inserted into the hole, thereby playing a sealing role.

[0052] It can be seen that in Example 1-1, the receiving seat 13 supports the aerosol generating product 200 by relying on the edge of the bottom wall 1311 thereof, and forms a continuous and relatively spacious groove, which reduces the corner positions that are prone to forming cleaning dead corners, and effectively improves the convenience of cleaning. For another example, in Example 1-2, Figure 5 As shown, compared with embodiment 1-1, the supporting portion 1312 in this embodiment includes two sub-supporting blocks 13121, which are circumferentially spaced and distributed at the edge of the bottom wall 1311, wherein the sub-supporting blocks 13121 are arc-shaped structures, and their length direction runs along the edge of the bottom wall 1311. Optionally, the two sub-supporting blocks 13121 are rotationally symmetrical around the center of the bottom wall 1311.

[0053] The two sub-supporting blocks 13121 respectively correspond to the side surfaces located inside the bottom wall 1311 to define the air guide groove 1313 (understandably, the projection of the side surface of the sub-supporting block 13121 on the bottom wall 1311, a part of the projection coincides with the edge line of the bottom wall 1311, and the projection of the remaining part is located inside the shape surrounded by the edge line of the bottom wall 1311, and the projection of the side surface of the sub-supporting block 13121 corresponding to the side surface located inside the bottom wall 1311 on the bottom wall 1311 is the projection inside the shape surrounded by the edge line of the bottom wall 1311.), the shape of the air guide groove 1313 is a spiral shape, and the interval between the ends of the two sub-supporting blocks 13121 forms two air inlets 13131 of the air guide groove 1313. Most of the area of ​​the entire air guide groove 1313 is smoothly distributed and concentrated in the inner position of the bottom wall 1311.

[0054] Understandably, the air guide groove 1313 of Example 1-1 has only one air inlet 13131. As the air guide groove 1313 extends, the closer to the end of the air guide groove 1313, the smaller the air flow rate, so the end of the air guide groove 1313 is prone to form a dead zone. Therefore, by increasing the number of air inlets 13131, such as greater than or equal to 2, the air flow distribution of the air guide groove 1313 can be relatively more uniform. Secondly, the vortex-shaped arrangement of the air guide groove 1313 can also make the airway smoother and more fluent.

[0055] In Example 1-2, a centrally arranged convex portion 1314 is formed on the bottom wall 1311, and a through hole 1315 is formed through the convex portion 1314 for inserting the microwave radiation structure 122. The convex portion 1314 is located at the air guide groove 1313, and its height can be consistent with that of the supporting portion 1312, or it can be slightly lower or higher than the height of the supporting portion 1312. The design of the convex portion 1314 can ensure that there is no extra gap between the microwave radiation structure 122 when the microwave radiation structure 122 is inserted into the jack, and the convex portion 1314 plays a sealing role, preventing the generated condensate from leaking into the cavity 113 through the gap between the microwave radiation structure 122 and the jack, thereby affecting the operation of the cavity 113.

[0056] For example, in Embodiment 1-3, Figure 6 As shown, the main difference from Embodiment 1-2 is that the supporting portion 1312 of this embodiment includes three sub-supporting blocks 13121 circumferentially spaced and distributed at the edge of the bottom wall 1311. The three sub-supporting blocks 13121 each correspond to the side surface located in the bottom wall 1311 to define the air guide groove 1313, and the intervals between the ends of the three sub-supporting blocks 13121 form three air inlets 13131 of the air guide groove 1313.

[0057] For example, in Embodiment 1-4, Figure 7As shown, the main difference from Examples 1-3 is that the sub-support block 13121 of this embodiment is roughly triangular, and the area distribution portion of the sub-support block 13121 extends to the inner position of the bottom wall 1311, so that the area of ​​the air guide groove 1313 of this embodiment is smaller than the area of ​​the air guide groove 1313 of Examples 1-3.

[0058] For example, in Embodiment 1-5, Figure 8 As shown, the main difference from Embodiment 1-2 is that the supporting portion 1312 of this embodiment includes four sub-supporting blocks 13121, which are circumferentially spaced and distributed at the edge of the bottom wall 1311, wherein the sub-supporting blocks 13121 are roughly triangular. Optionally, the four sub-supporting blocks 13121 are rotationally symmetrical around the center of the bottom wall 1311.

[0059] The four sub-supporting blocks 13121 respectively correspond to the side surfaces located in the bottom wall 1311 to define an air guide groove 1313 , and the intervals between the four sub-supporting blocks 13121 form four air inlets 13131 of the air guide groove 1313 .

[0060] For example, in Embodiment 1-6, Fig. 9 As shown, the main difference from Example 1-2 is that the supporting portion 1312 of this embodiment includes a large and a small sub-supporting block 13121, wherein the large sub-supporting block 13121 is U-shaped, and its length direction runs along the edge of the bottom wall 1311, and the small sub-supporting block 13121 is arc-shaped, arranged at the edge of the bottom wall, and located between the two ends of the large sub-supporting block 13121, and maintaining a distance from the two ends of the large sub-supporting block 13121.

[0061] A large and a small sub-support block 13121 each correspond to a side surface located within the bottom wall 1311 to define an air guide groove 1313, wherein the two ends of the large sub-support block 13121 and the interval between the small sub-support block 13121 form two air inlets 13131 of the air guide groove 1313, and the two air inlets 13131 are located on the same semicircle, which is a semicircle with the center falling on the center of the bottom wall 1311.

[0062] It can also be that embodiments 1-7, such as Fig.10 As shown, the main difference from Embodiments 1-6 is that the supporting portion 1312 of this embodiment includes two large and two small sub-supporting blocks 13121, which are circumferentially spaced and distributed at the edge of the bottom wall 1311. Optionally, the two large and two small sub-supporting blocks 13121 are arranged in an alternating manner of one large and one small.

[0063] The two large and two small sub-supporting blocks 13121 each correspond to the side surfaces located within the bottom wall 1311 to define an air guide groove 1313, and the air guide groove 1313 is in an I-shape. The intervals between the two large and two small sub-supporting blocks 13121 form four air inlets 13131 of the air guide groove 1313, wherein two of the air inlets 13131 are located on the same straight line, and the other two air inlets 13131 are located on another straight line, and the two straight lines are parallel.

[0064] Based on the above described embodiments 1-1 to 1-7, Figures 4 to 10 It can be seen that the bottom wall 1311 is formed with a supporting portion 1312 and an air guide groove 1313, most or all of the area of ​​the supporting portion 1312 is distributed at the edge of the bottom wall 1311, and the air guide groove 1313 is formed at the inner periphery of the supporting portion 1312, and most of its area is smoothly distributed and concentrated at the inner position of the bottom wall 1311. The proportion of the air guide groove 1313 on the bottom wall 1311 is greater than the proportion of the supporting portion 1312 on the bottom wall 1311.

[0065] The air inlet 13131 of the air guide groove 1313 can be provided with one or more air inlets 13131, but in order to reduce the cleaning dead angle, the number of air inlets 13131 can be controlled within four, in other words, the number of sub-supporting blocks 13121 also needs to be controlled within four. The path extending from the air inlet 13131 in the air guide groove 1313 to the inside of the bottom wall 1311 can be arranged in an arc shape to make the airflow smoother when the air is inhaled.

[0066] Through the above-mentioned design, the air guide grooves 1313 are concentrated as much as possible inside the bottom wall 1311 by relying on the support around them. On the one hand, a smooth, concentrated and relatively spacious groove can be formed to avoid the air guide grooves 1313 being divided into small grooves by the supporting portion 1312, thereby reducing cleaning dead corners and effectively improving the convenience of cleaning. On the other hand, the flow rate of the airflow in the aerosol generating product 200 can be increased, especially the flow rate around the microwave radiation structure 122, so that the aerosol can be quickly brought out, which is conducive to increasing the amount of mist output and Mouth feel (Understandably, the area distribution of the air guide grooves 1313 in the related art is dispersed, and the air is evenly distributed at various positions of the bottom wall 1311, so the inhalation area is large, and the speed of the airflow into the aerosol generating product 200 is slow. The area distribution of the air guide grooves 1313 of the present invention is concentrated as much as possible at the inner position of the bottom wall 1311, which means that enough air can be located at the inner position of the bottom wall 1311, and the inhalation area is relatively small, and the speed of the airflow into the aerosol generating product 200 can be faster and more concentrated.

[0067] In some embodiments, refer again to Figure 3 as well as Figure 4 The receiving seat 13 may further include a plurality of longitudinal positioning ribs 134 .

[0068] like Figure 3 As shown, these positioning ribs 134 are evenly spaced and arranged on the inner peripheral wall of the receiving portion 132, and each positioning rib 134 extends in a direction parallel to the axis of the receiving seat 13. Optionally, one end of any positioning rib 134 is located at the top edge of the receiving portion 132, and the other end thereof extends longitudinally downward, but there is a gap between the bottom wall 1311. These positioning ribs 134 can be used to clamp the aerosol generating product 200 inserted into the receiving portion 132 on one hand, and can form an air intake channel on the inner periphery of the receiving portion 132 on the other hand, so as to facilitate the ambient air to be sucked into the air guide groove 1313 located on the bottom wall 1311. Moreover, maintaining a gap between the positioning rib 134 and the bottom wall 1311 can increase the width of the part of the air intake channel located between the positioning rib 134 and the bottom wall 1311, and it is also more convenient to clean.

[0069] like Figure 3 As shown, in some embodiments, the fixing portion 133 may be annular, coaxially and integrally combined with the top periphery of the receiving portion 132 , and the outer diameter of the fixing portion 133 is slightly larger than the inner diameter of the outer conductor unit 11 .

[0070] See also Figure 3 In some embodiments, the microwave matching structure 121 is arranged between the conductor end wall 115 and the receiving seat 13 , and the microwave matching structure 121 may include a conductor column 1211 and a conductor disk 1212 .

[0071] In some embodiments, Figure 3 As shown, the conductor post 1211 is cylindrical. Of course, the conductor post 1211 is not limited to being cylindrical, and may also be in other shapes such as square column, elliptical column, stepped column, irregular column, etc. The end (bottom end) of the conductor post 1211 away from the open end 112 of the outer conductor unit 11 is a fixed end, coaxially fixed on the conductor end wall 115 of the outer conductor unit 11, and the end (top end) close to the open end 112 is a free end, extending toward the open end 112 of the outer conductor unit 11 and located below the receiving seat 13. The diameter of the conductor post 1211 is smaller than the inner diameter of the outer conductor unit 11.

[0072] The conductor column 1211 can be made of a conductive metal material, preferably aluminum alloy or copper. It is understandable that the conductor column 1211 is not limited to being made of a conductive material, and can also be realized by plating a conductive coating on the outer surface of a non-conductive body. The conductive coating can be a silver coating or a gold coating.

[0073] The conductor post 1211 is also provided with a plug hole relative to the feeding hole 116, and the plug hole is used for inserting one end of the microwave feeding unit 14 extending into the cavity 113 to improve the connection reliability between the conductor post 1211 and the inner conductor. The plug hole is a blind hole, cylindrical, and extends radially along the outer peripheral wall of the conductor post 1211 to the inside of the conductor post 1211.

[0074] In some embodiments, Figure 3 As shown, the conductor disk 1212 is in the shape of a disk. Of course, the shape of the conductor disk 1212 is not limited to a disk, and it can also be in the shape of a square column, a truncated cone, etc. The diameter of the conductor disk 1212 is smaller than the inner diameter of the outer conductor unit 11, and the diameter of the conductor disk 1212 is larger than the diameter of the conductor column 1211.

[0075] The conductor plate 1212 is combined on the top of the conductor post 1211, and can be integrated with the conductor post 1211, or can be in ohmic contact with the conductor post 1211. Meanwhile, the conductor plate 1212 and the bottom of the receiving seat 13 are not in contact, and have a third distance in the axial direction.

[0076] The conductor plate 1212 can be made of a conductive metal material, preferably aluminum alloy or copper. It is understandable that the conductor plate 1212 is not limited to being made of a conductive material, and can also be realized by plating a conductive coating on the outer surface of a non-conductive body. The conductive coating can be a silver coating or a gold coating.

[0077] See also Figure 3 In some embodiments, the microwave radiation structure 122 may include a longitudinal probe; the bottom end of the probe is coaxially and fixedly embedded in the microwave matching structure 121 to form a good ohmic contact with the microwave matching structure 121; the top end of the probe longitudinally extends upward into the receiving cavity 130. It can be understood that when the aerosol generating article 200 extends into the receiving seat 13, it is inserted at the periphery of the probe.

[0078] Optionally, the shape of the probe tip end may include a plane, a sphere, an ellipsoid, a cone or a truncated cone; a truncated cone is preferred because it can enhance the local field strength and thereby accelerate the atomization speed of the aerosol generating product 200.

[0079] The probe can be made of a conductive metal material, preferably stainless steel, aluminum alloy or copper. It is understandable that the probe is not limited to being made of a conductive material, and can also be realized by plating a conductive coating on the outer surface of a non-conductive body. The conductive coating can be a silver coating or a gold coating.

[0080] See also Figure 3In some embodiments, the microwave feeding unit 14 may be a coaxial connector, which is inserted from a feeding hole 116 located on the peripheral side of the outer conductor unit 11 and mounted on the outer conductor unit 11. The microwave feeding unit 14 includes an outer conductor (not specifically shown), an inner conductor (not specifically shown) disposed inside the outer conductor, and a dielectric layer (not specifically shown) between the inner conductor and the outer conductor.

[0081] The outer conductor is a cylindrical structure with open ends. When the microwave feeding unit 14 is installed on the outer conductor unit 11 , the side wall of the outer conductor is in ohmic contact with the inner wall surface of the feeding hole 116 .

[0082] like Figure 3 As shown, the inner conductor is a straight needle structure, one end of which is a connection end 1421, which is located inside the outer conductor; the other end is a feed end 1422, which is located outside the outer conductor. The connection end 1421 is used to connect to the microwave generating component to access the microwave; the connection method can be a coaxial connection method or a microstrip line connection method. When the microwave feeding unit 14 is installed on the outer conductor unit 11, the feed end 1422 is relatively adjacent to the conductor column 1211, and can be inserted into the jack located on the conductor column 1211 (see Figure 2 ) to achieve electrical coupling or magnetic coupling to guide microwaves to the inner conductor unit 12.

[0083] Of course, the shape of the inner conductor is not limited to a straight line. In other embodiments, the inner conductor may also be L-shaped (not shown), which may include a first section perpendicular to the axis of the microwave heating component 1 and a second section parallel to the axis of the microwave heating component 1. The first section is partially located in the outer conductor, and one end of the first section connected to the second section extends out of the outer conductor. Preferably, the first section and the second section are integrally formed.

[0084] In this embodiment, the end of the second section away from the first section can be in direct ohmic contact with the conductor end wall 115 of the outer conductor unit 11, or the position of the socket can be set on the conductor end wall 115, and the end of the second section away from the first section is inserted into the socket of the conductor end wall 115.

[0085] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
