Description

Technical Field

[0001] This application relates to the field of material feeding technology, and in particular to a feeder and reaction equipment. Background Technology

[0002] In industries such as chemical, food, and pharmaceutical, feeders are crucial unit equipment used to continuously and uniformly deliver granular materials into the reaction chamber of reaction equipment. However, in related technologies, the feeding process using feeders is complex and difficult, increasing the complexity of the reaction equipment and its floor space requirements. Utility Model Content

[0003] In view of this, this application provides a feeder and a reaction device, aiming to solve the problems of complex feeding process, difficult feeding, high complexity of reaction device and large footprint in related technologies.

[0004] In a first aspect, this application provides a feeder, comprising: a plurality of feeding components and a transmission component. Each feeding component includes a feeding tray and a distributing tray stacked on top of each other; the feeding trays of the plurality of feeding components are relatively fixed; the feeding tray has a feeding port; the distributing tray has a plurality of spaced-apart distributing ports, the equivalent diameters of the distributing ports of different feeding components being different; in each of the feeding components, the distributing tray is movable relative to the feeding tray, such that one of the plurality of distributing ports is in communication with the feeding port; the transmission component is connected to the distributing trays of the plurality of feeding components respectively, and the movement of the transmission component selectively drives one of the distributing trays of the plurality of feeding components to move accordingly.

[0005] According to the embodiments of this application, the feeder, on the one hand, utilizes a transmission component connected to the distribution discs of multiple feeder components, thereby integrating multiple feeder components together. This allows a single feeder to feed various granular materials of different specifications, avoiding the problems of complex feeding processes and difficulties caused by repeatedly changing feeders during production in related technologies. This improves production efficiency and reduces equipment complexity and floor space. On the other hand, when the transmission component moves under external force, it can selectively drive one of the distribution discs of the multiple feeder components to move accordingly. This ensures that when the feeder is working, the feeder component that moves with the transmission component feeds, while the other feeder components do not feed. This helps ensure that the feeder only feeds one type of granular material during operation, preventing material mixing during the feeding process. This at least improves the control of feeding different specifications of granular materials, increases the accuracy of the feeding ratio, and enhances the reliability of the feeder.

[0032] In related technologies, feeders are typically single-layered structures, capable of delivering only one type of granular material into the reaction chamber of a reaction device. For production processes requiring the simultaneous addition of two or more different sizes of granular materials, multiple feeders are often necessary. On one hand, the constant switching between multiple feeders during production requires production line workers to focus more on feeder selection, increasing the difficulty of the process and complicating the feeding process, thus reducing production efficiency. On the other hand, the use of multiple feeders undoubtedly increases the complexity of the equipment and its floor space requirements.

[0033] To address the aforementioned technical problems, this application provides a feeder and a reaction apparatus having the feeder. The specific structure of the reaction apparatus of this application will be described in detail below with reference to the accompanying drawings.

[0034] Please see Figure 1 The reaction equipment 100 includes a reaction chamber 20 and a feeder 10.

[0035] The reaction chamber 20 has a feeding port (not shown in the figure). The opening shape of the feeding port includes, but is not limited to, circular, rectangular, triangular or irregular shapes.

[0036] Specifically, the feeding port can be located at the top of the reaction chamber 20, which facilitates the entry of materials into the reaction chamber 20 under the influence of gravity. Of course, this application is not limited to this; in other embodiments, the feeding port can also be located on the side of the reaction chamber 20.

[0037] The reaction chamber 20 can contain containers such as crucibles to receive granular materials.

[0038] The feeder 10 is installed in the reaction chamber 20. The feeder 10 can add various granular materials of different specifications into the reaction chamber 20 through the feed port.

[0039] Please see Figure 2 The feeder 10 includes: multiple feeding components 1 and transmission components 3. Figure 2 The following explanation uses two components, 1 and 2, as an example.

[0040] Multiple feeding components 1 can be used to feed granular materials of different specifications.

[0041] Please see Figure 3 and Figure 4 Each feeding component 1 includes a feeding tray 11 and a distributing tray 12.

[0042] The shape of the feeding tray 11 includes, but is not limited to, a circle, rectangle, triangle, or irregular shape. The material of the feeding tray 11 includes, but is not limited to, metal or plastic.

[0043] The feeding trays 11 of the multiple feeding components 1 are relatively fixed. That is, the feeding trays 11 of the multiple feeding components 1 are relatively stationary and are directly or indirectly fixed together.

[0044] The feeding tray 11 has a feeding port 111. The feeding port 111 extends through the feeding tray 11 in the thickness direction. The opening shape of the feeding port 111 is not limited to circular, rectangular, triangular or irregular. The longitudinal cross-sectional shape of the feeding port 111 is not limited to rectangular, trapezoidal or irregular.

[0045] The discharge port 111 can be used to connect with the feeding port mentioned above. For example, the discharge port 111 and the feeding port are directly opposite each other in the direction of gravity to achieve connection. Of course, this application is not limited to this. In other examples, the discharge port 111 and the feeding port can also be connected through pipelines or the like.

[0046] The material distribution tray 12 and the material unloading tray 11 are stacked. Specifically, in actual use, the material distribution tray 12 and the material unloading tray 11 can be stacked in the direction of gravity (i.e., the up and down direction), and the material distribution tray 12 is located above the material unloading tray 11.

[0047] The shape of the dispensing tray 12 includes, but is not limited to, a circle, a rectangle, a triangle, or an irregular shape. The material of the dispensing tray 12 includes, but is not limited to, metal or plastic.

[0048] The dispensing disc 12 has a plurality of spaced-apart dispensing ports 121. Granular materials can be dispensed into each dispensing port 121 at the dispensing disc 12. The opening shape of the dispensing port 121 includes, but is not limited to, circular, rectangular, triangular or irregular shapes.

[0049] For example, to prevent particulate material from overflowing from the outer periphery of the distribution plate 12 before being distributed into the distribution port 121, please refer to... Figure 3 and Figure 4 The outer periphery of the feeding tray 11 is provided with a protective cylinder 15 that protrudes towards the side where the distributing tray 12 is located. In this way, the protective cylinder 15 and the feeding tray 11 can form a receiving space, within which the distributing tray 12 is located. Based on this, for example, the protective cylinder 15 and the feeding tray 11 can be integrally molded, thereby simplifying the overall processing technology of the protective cylinder 15 and the feeding tray 11, reducing manufacturing costs, and improving the connection reliability of the protective cylinder 15 and the feeding tray 11. Of course, this application is not limited to this; the protective cylinder 15 and the feeding tray 11 can also be assembled together by welding, gluing, or screw connection.

[0050] Of course, it is understood that the location of the protective cylinder 15 is not limited to this. In other embodiments, the protective cylinder 15 may also be located on the outer periphery of the distribution plate 12 and protrude from the distribution plate 12 in a direction opposite to the feed plate 11. The connection relationship between the protective cylinder 15 and the distribution plate 12 can be referred to the protective cylinder 15 and the feed plate 11 mentioned above, and will not be repeated here.

[0051] For example, the material of the protective sleeve 15 includes, but is not limited to, metal or plastic.

[0052] The equivalent diameter of the dispensing port 121 of different feeding components 1 is different. That is, the equivalent diameter of the dispensing port 121 of any two feeding components 1 is different. In this way, different feeding components 1 can be used for granular materials of different particle sizes, thereby enabling the feeding of various specifications of granular materials.

[0053] It is worth noting that the "equivalent diameter" refers to the diameter of a circle with the same opening area as the feed outlet 121. In other words, when the feed outlet 121 is circular, this equivalent diameter is the diameter of the circle.

[0054] In each feeding component 1, the distribution plate 12 is movable relative to the feeding plate 11, such that one of the plurality of distribution ports 121 is connected to the feeding port 111. In this way, since the particulate material is distributed into each distribution port 121 at the distribution plate 12, when the distribution plate 12 moves relative to the feeding plate 11 so that one of the plurality of distribution ports 121 is connected to the feeding port 111, the particulate material in the distribution port 121 connected to the feeding port 111 can be discharged from the feeding component 1 through the feeding port 111, thereby facilitating the entry of the particulate material into the aforementioned reaction chamber 20.

[0055] It is understood that the movement of the material distribution plate 12 relative to the material feeding plate 11 includes, but is not limited to, rotation, translation, and a combination of the two.

[0056] The transmission component 3 is connected to the distributing discs 12 of multiple feeding components 1 respectively. When the transmission component 3 moves under the drive of an external force, it can selectively drive one of the distributing discs 12 of the multiple feeding components 1 to move accordingly. That is to say, when the transmission component 3 moves under the drive of an external force, it can selectively drive different distributing discs 12 of the feeding components 1 to rotate at different times.

[0057] In this way, on the one hand, by connecting the transmission component 3 with the distribution discs 12 of multiple feeding components 1, multiple feeding components 1 can be integrated together, enabling a single feeder 10 to feed multiple different specifications of granular materials. This avoids the problems of complex feeding processes and difficulties caused by repeatedly changing the feeder 10 during production, which is beneficial to improving production efficiency and reducing equipment complexity and floor space. On the other hand, when the transmission component 3 moves under the drive of external force, it can selectively drive one of the distribution discs 12 of the multiple feeding components 1 to move accordingly. This allows the feeding component 1 that moves with the transmission component 3 to feed materials while the other feeding components 1 do not feed materials. This helps ensure that the feeder 10 only feeds one type of granular material during operation, preventing material mixing during the feeding process. This helps to improve the feeding control of different specifications of granular materials to a certain extent, improve the accuracy of the feeding ratio, and improve the feeding reliability of the feeder 10.

[0058] Please refer to some embodiments of this application. Figure 2 , Figure 3 and Figure 4 Multiple feeding components 1 are arranged sequentially in the stacking direction (i.e., the vertical direction) of the feeding tray 11 and the distributing tray 12. In this way, the entire feeder 10 occupies a relatively small size in the circumferential direction of the feeding tray 11, and the structure is more compact.

[0059] Please refer to some embodiments of this application. Figure 3 and Figure 4 The transmission component 3 includes a transmission shaft 31 and a transmission structure 32.

[0060] The axial direction of the drive shaft 31 is consistent with the stacking direction of the feed plate 11 and the distribution plate 12. The material of the drive shaft 31 includes, but is not limited to, metal or plastic.

[0061] The drive shaft 31 passes sequentially through the distribution discs 12 and the discharge discs 11 of the multiple feeding components 1 along its own axial direction. The drive shaft 31 rotates to selectively drive one of the distribution discs 12 of the multiple feeding components 1 to rotate synchronously. In this way, the distribution disc 12 rotates relative to the discharge disc 11 around the axis of the drive shaft 31, resulting in a smaller circumferential dimension of the entire feeder 10 on the discharge disc 11, making the structure more compact.

[0062] Based on this, for example, when the distributing disc 12 rotates relative to the unloading disc 11, in order to ensure that one of the multiple distributing ports 121 is connected to the unloading port 111, for example, the multiple distributing ports 121 are distributed at intervals in the circumferential direction of the distributing disc 12, and the distance between the multiple distributing ports 121 on the distributing disc 12 and the axis of the drive shaft 31 is equal. For example, the multiple distributing ports 121 are evenly distributed at intervals in the circumferential direction of the distributing disc 12. Of course, this application is not limited to this. In other embodiments, the multiple distributing ports 121 are distributed at unequal intervals in the circumferential direction of the distributing disc 12, as long as the distance between the multiple distributing ports 121 on the distributing disc 12 and the axis of the drive shaft 31 is equal.

[0063] For details, please continue reading. Figure 3 and Figure 4 As shown, each feeding component 1 has a first shaft hole 122 on its feeding disc 12. The feeding disc 11 has a second shaft hole 112. The drive shaft 31 passes through the first shaft hole 122 on the feeding disc 12 and the second shaft hole 112 on the feeding disc 11 in sequence.

[0064] Since the feed tray 11 is stationary, to prevent the feed tray 11 from rotating when the drive shaft 31 rotates, the size of the second shaft hole 112 can be set to be larger than the outer diameter of the drive shaft 31, for example. In other embodiments, a rolling bearing can also be provided between the inner peripheral wall of the second shaft hole 112 of the feed tray 11 and the outer peripheral wall of the drive shaft 31.

[0065] Please continue reading. Figure 3 and Figure 4 There are multiple transmission structures 32. Each transmission structure 32 corresponds one-to-one with a multiple feeding component 1. Each transmission structure 32 is connected between the transmission shaft 31 and the corresponding feeding component 1's distribution plate 12.

[0066] Multiple transmission structures 32 allow one of the dispensing discs 12 of the multiple feeding components 1 to rotate synchronously with the rotation of the transmission shaft 31. This results in a simpler and more compact structure.

[0067] Please refer to some specific examples in this application. Figure 4 and Figure 5 There are two feeding components 1 and two transmission structures 32.

[0068] Each transmission structure 32 includes an inner ratchet 321 and a pawl 322. The inner ratchet 321 is fixed to the distribution disc 12 and surrounds the outer periphery of the transmission shaft 31. The pawl 322 is fixed to the transmission shaft 31 and is located inside the inner ratchet 321.

[0069] For details, please refer to Figure 4 and Figure 5Each inner ratchet 321 has a plurality of ratchet teeth 3211 evenly spaced in the circumferential direction of the inner ratchet 321. Each ratchet tooth 3211 has a mating surface 32111 and a guide surface 32112 facing away from each other. The included angle between the mating surface 32111 and the guide surface 32112 of each ratchet tooth 3211 is less than 90°. In two adjacent ratchet teeth 3211, the mating surface 32111 of one ratchet tooth 3211 is adjacent to the guide surface 32112 of the other ratchet tooth 3211.

[0070] When the drive shaft 31 rotates in a first orientation (e.g., clockwise), the pawl 322 of one of the drive structures 32 (which can be called the first drive structure) engages with the inner ratchet 321 (that is, it abuts against the mating surface 32111 of one of the ratchet teeth 3211 of the inner ratchet 321) to drive the material distribution disc 12 of the corresponding feeding component 1 (which can be called the first feeding component) to rotate synchronously. Meanwhile, the pawl 322 of the other drive structure 32 (which can be called the second drive structure) disengages from the inner ratchet 321 (that is, the pawl 322 disengages from the inner ratchet 321 under the guidance of the guide surface 32112 of the inner ratchet 321). In this way, the first feeding component can feed material, while the second feeding component does not.

[0071] When the drive shaft 31 rotates in the second orientation (e.g., counterclockwise), the pawl 322 of another drive structure 32 (i.e., the second drive structure) engages with the inner ratchet 321 (i.e., abuts against the mating surface 32111 of one of the ratchet teeth 3211 of the inner ratchet 321) to drive the material distribution disc 12 of the corresponding unloading component 1 (i.e., the second unloading component) to rotate synchronously. Meanwhile, the pawl 322 of one of the drive structures 32 (i.e., the first drive structure) disengages from the inner ratchet 321 (i.e., the pawl 322 disengages from the inner ratchet 321 under the guidance of the guide surface 32112 of the inner ratchet 321). In this way, the second unloading component can unload material while the first unloading component does not.

[0072] In this way, the entire transmission structure 32 has a simple structure, is easy to process and manufacture, helps to reduce costs, and the transmission effect of the two transmission structures 32 between the transmission shaft 31 and the two unloading parts 1 is highly reliable.

[0073] Based on this, in some embodiments, the material distribution disc 12 of the feeding component 1 and the inner ratchet 321 of the transmission structure 32 corresponding to the feeding component 1 are integrally formed. This simplifies the processing of the material distribution disc 12 and the inner ratchet 321, reducing processing costs, and also improves the connection strength between the inner ratchet 321 and the material distribution disc 12. Of course, this application is not limited to this; in other embodiments, the material distribution disc 12 of the feeding component 1 and the inner ratchet 321 of the transmission structure 32 corresponding to the feeding component 1 can also be assembled by welding, screw connection, or snap-fitting.

[0074] In some specific examples, the surface of the distribution plate 12 facing the feed plate 11 is recessed away from the feed plate 11 to form a mating cavity, and the inner ratchet 321 is integrally formed on the inner circumferential surface of the mating cavity. In this way, the overall structure of the inner ratchet 321 and the distribution plate 12 is more compact and smaller in size.

[0075] For details, please refer to Figure 6 The pawl 322 includes a connector 3221, a wedge block 3222, and an elastic element 3223.

[0076] The connecting member 3221 is fixedly connected to the drive shaft 31, and the elastic member 3223 is connected between the wedge block 3222 and the connecting member 3221. The elastic member 3223 applies a spring force from the connecting member 3221 to the wedge block 3222. In this way, by setting the elastic member 3223 in the pawl 322, it is possible to facilitate the extension and retraction of the pawl 322 in the arrangement direction of the connecting member 3221 and the wedge block 3222. On the one hand, it is possible to facilitate the reliable engagement of the pawl 322 with the ratchet teeth 3211 of the inner ratchet wheel 321 of the distributing plate 12, so that the transmission structure 32 where the pawl 322 is located drives the corresponding distributing plate 12 to rotate. On the other hand, it is possible to facilitate the disengagement of the pawl 322 from the ratchet teeth 3211 of the inner ratchet wheel 321 of the distributing plate 12, so that the transmission structure 32 where the pawl 322 is located does not drive the corresponding distributing plate 12 to rotate.

[0077] For example, the connector 3221 is a sleeve. The elastic element 3223 is located inside the sleeve. In this way, on the one hand, the structure of the entire pawl 322 is more compact, and on the other hand, the sleeve can also guide the extension and retraction of the elastic element 3223, which helps to improve the reliability of the operation of the elastic element 3223.

[0078] In other embodiments, the wedge block 3222 is a sleeve. The elastic element 3223 is located inside the sleeve. In this way, on the one hand, the entire structure of the pawl 322 is more compact, and on the other hand, the sleeve can also guide the extension and retraction of the elastic element 3223, which helps to improve the reliability of the operation of the elastic element 3223.

[0079] For example, the elastic element 3223 is a compression spring. As a result, the structure is simple and the cost is low.

[0080] In some specific examples of this application, in order to facilitate the fixed connection between the pawl 322 and the drive shaft 31, a collar 323 is provided at one end of the pawl 322 near the drive shaft 31 (e.g., the connecting member 3221 mentioned above), and the collar 323 is interference-fitted onto the drive shaft 31. This facilitates the installation of the pawl 322 and the drive shaft 31.

[0081] For example, the connector 3221 and the collar 323 described above can be integrally formed. This simplifies the processing of the connector 3221 and the collar 323, reducing processing costs, and also improves the connection strength between them. Of course, this application is not limited to this; in other embodiments, the connector 3221 and the collar 323 can also be assembled using welding, screw connections, or other methods.

[0082] It is understood that the structural form of the transmission structure 32 is not limited to this. In other embodiments, each transmission structure 32 can also be formed by meshing gears and racks. The rack can be an arc extending circumferentially along the transmission shaft 31 and fixed to the distribution plate 12, while the gear can be fixed to the transmission shaft 31. As long as the racks of the transmission structures 3 corresponding to different feeding components 1 are distributed circumferentially on the transmission shaft 31 and staggered axially, this is sufficient. Regarding the fixing method of the rack on the distribution plate 12, refer to the ratchet 321 and the distribution plate 12 mentioned earlier; further details will not be provided here.

[0083] For some specific examples in this application, please refer to Figure 4 In two adjacent feeding components 1, a guide pipe 4 is fixed and connected to the feeding port 111 of the feeding tray 11 of one feeding component 1. The guide pipe 4 extends toward the distribution tray 12 of the other feeding component 1 and is directly opposite the feeding port 111 of the feeding tray 11 of the other feeding component 1. In this way, when the feeder 10 is placed vertically and the feeder 10 uses the upper feeding component 1 for feeding, the granular material at the feeding port 111 of the upper feeding component 1 can be guided into the feeding port 111 of the lower feeding component 1 through the guide pipe 4. The guide pipe 4, the distribution tray 121 and the feeding port 111 of the lower feeding component 1 can serve as the feeding path for the granular material at the feeding port 111 of the upper feeding component 1, which is beneficial to achieve partial overlap of the feeding paths in the feeder 10, thereby simplifying the structure of the feeder 10.

[0084] In some embodiments of this application, the discharge ports 111 of multiple feeding components 1 face each other in the stacking direction of the feeding tray 11 and the distributing tray 12. In this way, when the feeder 10 is placed vertically and the feeder 10 uses the upper feeding component 1 for feeding, the distributing port 121 and the discharge port 111 of the lower feeding component 1 can serve as the feeding path for the granular material of the upper feeding component 1's discharge port 111. This facilitates the overlap of some feeding paths in the feeder 10, thereby simplifying the structure of the feeder 10.

[0085] In some specific examples of this application, in the direction from the distribution plate 12 to the discharge plate 11 (e.g., from top to bottom), the equivalent diameter of the discharge port 111 of the discharge plate 11 of the upstream discharge component 1 (e.g., the upper discharge component 1) is smaller than the equivalent diameter of the discharge port 111 of the downstream discharge component 1 (e.g., the lower discharge component 1). In this way, when the feeder 10 is placed vertically, and the upper discharge component 1 of the feeder 10 uses the discharge port 111 of the lower discharge component 1 as the discharge path, it can be ensured that the granular material of the upper discharge component 1 can be smoothly discharged from the discharge port 111 of the lower discharge component 1, improving the reliability of the feeder 1's discharge.

[0086] In some specific examples of this application, in the direction from the distribution plate 12 to the discharge plate 11 (e.g., from top to bottom), the equivalent diameter of the distribution port 121 of the upstream discharge component 1 (e.g., the upper discharge component 1) is smaller than the equivalent diameter of the distribution port 121 of the downstream discharge component 1 (e.g., the lower discharge component 1). In this way, when the feeder 10 is placed vertically and the upper discharge component 1 of the feeder 10 uses the distribution port 121 of the lower discharge component 1 as the discharge path, it can be ensured that the granular material of the upper discharge component 1 can be smoothly discharged from the distribution port 121 of the lower discharge component 1, improving the reliability of the feeder 1's discharge.

[0087] For example, the equivalent diameter of the discharge port 111 on each feeding component 1 is larger than the equivalent diameter of the distribution port 121. This helps to ensure that the granular material in the distribution port 121 is smoothly discharged from the corresponding discharge port 111. Of course, in other embodiments, the equivalent diameter of the discharge port 111 on each feeding component 1 can also be equal to the equivalent diameter of the distribution port 121.

[0088] For example, the equivalent diameter of the feeding port 111 of the feeding tray 11 on different feeding components 1 is the same. In this way, when assembling the feeder 10, it is advantageous to select only one type of feeding tray 11, thereby simplifying the design and manufacturing cost of the feeding tray 11.

[0089] Based on this, the equivalent diameter of the feeding port 111 of any feeding disc 11 on any feeding component 1 is greater than the equivalent diameter of the distributing port 121 on any feeding component 1. This helps to improve the reliability of feeding by the feeder 1.

[0090] In some embodiments of this application, each feeding component 1 includes a distributing component 13. The distributing component 13 is fixed to the feeding tray 11, and a portion of the distributing component 13 is located on the side of the distributing tray 12 opposite to the feeding tray 11. In this way, when a large amount of material is placed on the surface of the distributing tray 12 opposite to the feeding tray 11, the distributing component 13 can push the granular material on the distributing tray 12 by driving the distributing tray 12, thereby pushing the granular material into the distributing port 121.

[0091] For example, the material distribution component 13 can be an elastic structure. In this way, on the one hand, the material distribution component 13 can ensure the function of distributing granular materials on the material distribution plate 12, and on the other hand, it can prevent the material distribution component 13 from interfering with the rotation of the material distribution plate 12 relative to the feed plate 11.

[0092] For example, the dividing component 13 is a wire-like structure. For instance, the material of the dividing component 13 is aluminum or iron.

[0093] For example, the material distribution component 13 can be fixed to the end of the protective cylinder 15 opposite to the feed tray 11. This can prevent the material distribution component 13 from interfering with the rotation of the material distribution tray 12 relative to the feed tray 11.

[0094] Based on any of the above embodiments, in some embodiments of this application, the feeder 10 may further include a drive motor. The drive motor is connected to a transmission shaft to drive the transmission shaft to rotate. This facilitates automated control of the feeder 10, thereby further improving the feeding control of granular materials of different specifications and increasing the accuracy of the feeding ratio.

[0095] Of course, this application is not limited to this. In other embodiments, the feeder 10 may not include a drive motor, but instead a manually driven transmission component 3.

[0096] In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples without contradicting each other.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
