Description

Technical Field

[0001] This utility model relates to a traditional Chinese medicine processing device, and more particularly to a centralized processing system for Danshen (Salvia miltiorrhiza). Background Technology

[0002] Traditional Chinese medicine, as an important component of traditional Chinese medicine, has been widely used to treat various diseases since ancient times. Danshen (Salvia miltiorrhiza) has a cultivation history of 200-300 years in China. Danshen from Sichuan, China, has a small head and thick branches, and the "Identification of Drug Production" records that Danshen from Pingwu County, Sichuan, is of the best quality. Danshen has the effects of promoting blood circulation and removing blood stasis, regulating menstruation and relieving pain, and calming the mind and relieving irritability. It is mainly used to treat women's menstrual disorders, postpartum abdominal pain due to blood stasis, injuries from falls, and restlessness.

[0003] However, in rural areas, after harvesting Salvia miltiorrhiza, farmers typically remove the mud and sand and pull off the fibrous roots by hand, then air-dry or kiln-dry it themselves. This process is labor-intensive, inefficient, and the quality of the processed Salvia miltiorrhiza is inconsistent due to differences in the skill of the farmers and the temperature variations in their own kilns. Furthermore, air-dried Salvia miltiorrhiza is prone to mold if it is not properly protected from rain and moisture. As a result, when cooperatives or Salvia miltiorrhiza production bases collect the farmers' Salvia miltiorrhiza, they cannot guarantee the uniformity of the quality. Therefore, it is necessary to design a centralized processing system for Salvia miltiorrhiza, which would allow cooperatives or Salvia miltiorrhiza production bases to process large quantities of Salvia miltiorrhiza centrally, eliminating the need for farmers to process it themselves. This would reduce the workload for farmers while ensuring the quality of the Salvia miltiorrhiza. Utility Model Content

[0004] This utility model provides a centralized processing system for Salvia miltiorrhiza, which features high automation, high efficiency, and stable quality of processed Salvia miltiorrhiza. The specific technical solution is as follows:

[0005] A centralized processing system for Salvia miltiorrhiza includes a processing plant comprising a first wall, a second wall, a third wall, and a fourth wall connected sequentially. A large door for workers to enter and exit is located on the first wall. The processing plant is equipped with a pre-cleaning device, a cleansing and shaping device, a moistening device, a slicing device, and a drying device. The pre-cleaning device includes an inlet and an outlet, and is horizontally positioned near the middle of the second wall. The corner of the second wall near the inlet can be used to store Salvia miltiorrhiza to be processed, and the corner near the outlet can be used to store transfer baskets for easy loading of the cleaned Salvia miltiorrhiza. The system also includes a cleansing and shaping device. The shaping device is located near the stacking and transfer baskets to facilitate the pouring of the cleaned Salvia miltiorrhiza into the impurity removal and shaping device for impurity removal and root removal. The steaming device can steam-moisten the Salvia miltiorrhiza after the impurity removal and shaping device. There are multiple steaming devices, which are located on the first wall near the door to facilitate the steam to escape from the door. There are multiple drying devices, which are arranged side by side near the third wall. The slicing device is located between the drying device and the steaming device. After steaming, the Salvia miltiorrhiza is sliced ​​by the slicing device and then evenly spread on the drying device for drying, thus completing the processing of Salvia miltiorrhiza.

[0006] Furthermore, the pre-cleaning device includes a connected cleaning pool and a sorting pool. A retrieval assembly is installed in the cleaning pool and the sorting pool. The retrieval assembly includes a retrieval conveyor belt with holes. One end of the retrieval conveyor belt is located at the bottom of the cleaning pool, and the other end of the retrieval conveyor belt is located at the bottom of the sorting pool. The retrieval conveyor belt can retrieve the Salvia miltiorrhiza from the bottom of the cleaning pool and transport it to the bottom of the sorting pool for workers to sort and put into transfer baskets.

[0007] Furthermore, an air blowing component is installed below the retrieval conveyor belt in the cleaning pool, which can blow air into the cleaning pool to make the Salvia miltiorrhiza in the cleaning pool tumble; a water tap is installed above the sorting pool.

[0008] Furthermore, the impurity removal and shaping device includes a roller, which is rotatably mounted on the lifting frame. One end of the roller is connected to the drive device. Multiple drainage holes are evenly arranged on the side of the roller near the drive device. The drive device can drive the roller to rotate. The other end of the roller is provided with an opening, through which the Salvia miltiorrhiza to be removed and shaped can enter the roller, and the removed and shaped Salvia miltiorrhiza can be poured out through the opening.

[0009] Furthermore, multiple spiral blades are evenly distributed inside the drum. When the drum rotates forward, the spiral blades can transport the Salvia miltiorrhiza to the bottom of the drum. When the drum rotates in reverse, the spiral blades can transport the Salvia miltiorrhiza to the opening of the drum and drop it out.

[0010] Furthermore, a buffer section is provided at the end of the spiral blade away from the inner wall of the drum, and the buffer section is arc-shaped.

[0011] Furthermore, the humidification device includes a humidification box with a steam inlet at the bottom. Water vapor can enter the humidification box through a pipe. Humidification grids are fixed at intervals inside the humidification box. The transfer basket containing the cleaned and shaped Salvia miltiorrhiza can be placed in the humidification box for humidification.

[0012] Furthermore, the drying device includes a kang (heated brick bed) and a combustion chamber. A horizontal smoke baffle is installed at the middle of the vertical direction inside the kang, dividing the interior into an upper smoke circulation zone and a lower smoke circulation zone. The upper and lower smoke circulation zones have exhaust vents and inlets on the same side, respectively. A smoke channel is provided at the end of the horizontal smoke baffle away from the exhaust vents and inlets to connect the upper and lower smoke circulation zones. The combustion chamber includes a combustion zone and a smoke exhaust zone. The combustion zone is connected to the smoke inlet, and the smoke exhaust zone is connected to the exhaust vent. The combustion zone burns fuels such as firewood to produce high-temperature smoke. The high-temperature smoke enters the lower smoke circulation zone through the smoke inlet, then enters the upper smoke circulation zone, and finally enters the smoke exhaust zone through the exhaust vent. The top of the smoke exhaust zone is connected to an exhaust pipe, which discharges the smoke outside the Salvia miltiorrhiza processing plant.

[0013] Furthermore, the smoke channel of the horizontal smoke baffle is located in the middle of the rear side, and a diversion component is installed in the middle of the lower smoke circulation zone. The diversion component can divert the high-temperature smoke entering from the smoke inlet, allowing the high-temperature smoke to flow on the left and right sides before entering the upper smoke circulation zone through the smoke channel in the middle of the rear side. An arc-shaped guide hood is installed in the upper smoke circulation zone near the smoke exhaust port, allowing the high-temperature smoke to enter the smoke exhaust port on the left and right sides.

[0014] Furthermore, a heat-conducting seat is installed at the top of the upper smoke circulation zone, and fins are installed on the heat-conducting seat. Soil is evenly spread above the heat-conducting seat, and the fins are inserted into the soil to form a kang surface.

[0015] This utility model's centralized processing system for Salvia miltiorrhiza rationally arranges all the necessary equipment within the processing plant, achieving centralized processing of Salvia miltiorrhiza. This results in high processing efficiency and low overall system cost, making it suitable for construction in rural areas for cooperatives or Salvia miltiorrhiza production bases to centrally process large quantities of Salvia miltiorrhiza. The system achieves two-stage cleaning of Salvia miltiorrhiza through the installation of a pre-cleaning device and a impurity removal and shaping device, ensuring effective cleaning. After cleaning, the Salvia miltiorrhiza undergoes a humidification process in a device near the plant entrance, preventing water vapor from remaining in the plant and affecting the working environment. Simultaneously, multiple humidification and drying devices are arranged side-by-side. Since the humidification and drying processes are lengthy, this system avoids the problem of the system being unable to process Salvia miltiorrhiza due to the occupation or damage of a single humidification or drying device, ensuring continuous processing, good system stability, higher efficiency, and consistent quality of the processed Salvia miltiorrhiza.

[0031] To better understand the purpose, function, and specific design scheme of this utility model, the centralized processing system for Salvia miltiorrhiza of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] like Figure 1-13 As shown, the centralized processing system for Salvia miltiorrhiza of this utility model includes a Salvia miltiorrhiza processing plant. The processing plant includes a first wall 11, a second wall 12, a third wall 13, and a fourth wall 14 connected in sequence. A large door for workers to enter and exit is provided on the first wall 11. The processing plant is equipped with a pre-cleaning device 2, a cleaning and shaping device 3, a moistening device 4, a slicing device 5, and a drying device 6. The pre-cleaning device 2 includes an inlet 21 and an outlet 22. The pre-cleaning device 2 is horizontally positioned near the middle of the second wall 12. The corner of the second wall 12 near the inlet 21 can be used to store Salvia miltiorrhiza to be processed, and the corner of the second wall 12 near the outlet 22 can be used to store transfer baskets 7 for easy loading and cleaning. The washed Salvia miltiorrhiza; the impurity removal and shaping device 3 is located near the stacking and transfer basket 7 to facilitate the pouring of the washed Salvia miltiorrhiza into the impurity removal and shaping device 3 for impurity removal and removal of fibrous roots; the steaming device 4 can steam-moisten the Salvia miltiorrhiza treated by the impurity removal and shaping device 3. There are multiple steaming devices 4, which are located near the door of the first wall 11 to facilitate the discharge of water vapor from the door; there are multiple drying devices 6, which are arranged side by side near the third wall 13; the slicing device 5 is located between the drying device 6 and the steaming device 4. After steaming, the Salvia miltiorrhiza is sliced ​​by the slicing device 5 and evenly spread on the drying device 6 for drying, thus completing the processing of Salvia miltiorrhiza.

[0033] Specifically, such as Figure 2-3 As shown, the pre-cleaning device 2 includes a cleaning pool 23 and a sorting pool 24 that are connected to each other. A retrieval assembly 25 is installed in the cleaning pool 23 and the sorting pool 24. The retrieval assembly 25 includes a retrieval conveyor belt with holes. One end of the retrieval conveyor belt is located at the bottom of the cleaning pool 23, and the other end of the retrieval conveyor belt is located at the bottom of the sorting pool 24. The retrieval conveyor belt can retrieve the Salvia miltiorrhiza from the bottom of the cleaning pool 23 and transport it to the bottom of the sorting pool 24 for workers to pick and put into the transfer basket 7.

[0034] Preferably, to prevent Salvia miltiorrhiza from entering the corners of the washing tank 23, retrieval baffles 26 are provided on both sides of the retrieval conveyor belt. The two retrieval baffles 26 and the upper surface of the retrieval conveyor belt form a Salvia miltiorrhiza impurity removal zone, with the inlet 21 above the Salvia miltiorrhiza impurity removal zone. The Salvia miltiorrhiza to be washed can be poured into the Salvia miltiorrhiza impurity removal zone through the inlet 21. It is understood that the Salvia miltiorrhiza to be washed will contain a small amount of stems and leaves, weeds, broken fibrous roots, and shriveled and broken Salvia miltiorrhiza tubers. At this time, they will float on the water surface due to the buoyancy of the water in the washing tank 23. In addition, since Salvia miltiorrhiza may have been stored for a certain period of time, mold may also grow on the surface of the Salvia miltiorrhiza. Therefore, the mold on the surface of the Salvia miltiorrhiza can be cleaned in the washing tank 23. The retrieval conveyor belt can retrieve the Salvia miltiorrhiza from underwater and transport it to the bottom of the sorting tank 24. Workers can sort the washed Salvia miltiorrhiza into the transfer basket 7 to achieve the effect of impurity removal and preliminary screening.

[0035] It is worth noting that, in order to improve the cleaning effect of the cleaning tank 23, an air blowing assembly 27 is installed below the retrieval conveyor belt inside the cleaning tank 23. The air blowing assembly 27 can blow air into the cleaning tank 23 to make the Salvia miltiorrhiza inside the cleaning tank 23 tumble, thereby improving the cleaning effect. The air blowing assembly 27 includes a perforated pipe, one end of which is connected to a blower, which is located outside the cleaning tank 23.

[0036] Preferably, in this embodiment, a water tap 28 is provided above the sorting pool 24, allowing workers to further clean the unclean Salvia miltiorrhiza to improve the pre-cleaning effect. In addition, to facilitate workers' control of the retrieval conveyor belt and the water tap 28, a control pedal 29 is provided on the ground below the sorting pool 24. The control pedal 29 can control the movement of the retrieval conveyor belt and the closing of the water tap 28.

[0037] like Figure 4 As shown, the impurity removal and shaping device 3 includes a roller 31, which is rotatably mounted on a lifting frame 32. One end of the roller 31 is connected to a drive device 33, which drives the roller 31 to rotate. The other end of the roller 31 has an opening, through which the Salvia miltiorrhiza to be removed and shaped can enter the roller 31, and the removed and shaped Salvia miltiorrhiza can be poured out through the opening. When the roller 31 is removing impurities and shaping, the end of the lifting frame 32 near the opening of the roller 31 is raised so that the height of the opening end of the roller 31 is higher than the height of the end of the roller 31 away from the opening, so as to prevent the Salvia miltiorrhiza from falling out. When the roller 31 is tilting, the end of the lifting frame 32 near the opening of the roller 31 is lowered so that the height of the opening end of the roller 31 is lower than the height of the end of the roller 31 away from the opening, so as to facilitate the pouring out of the Salvia miltiorrhiza in the roller 31. A guide groove 34 is provided below the opening end of the roller 31, and a transfer basket 7 can be placed at the outlet of the guide groove 34. The Salvia miltiorrhiza in the roller 31 can slide into the transfer basket 7 through the guide groove 34.

[0038] Specifically, after pre-washing, the surface of the Salvia miltiorrhiza still retains some tightly adhered mud and sand, as well as mud and sand residue in the folds and crevices. After the Salvia miltiorrhiza is tumbled and shaken inside the drum 31, the residual mud and sand will fall off. Multiple drainage holes 331 are evenly distributed on the side of the drum 31 near the drive device 33. Workers can inject water into the drum 31 using a water pipe, and the water and mud inside the drum 31 can be discharged through the drainage holes 331. Additionally, the fibrous roots of the Salvia miltiorrhiza can also be inserted into the drainage holes 331, so that during the rotation of the drum 31, the fibrous roots are separated from the Salvia miltiorrhiza due to shearing force and fall to the outside of the drum 31. When the Salvia miltiorrhiza is cleaned, stop injecting water into the drum 31. Continuing to rotate the drum 31 at this time will achieve the effect of spin-drying.

[0039] Preferably, multiple spiral blades 35 are evenly distributed inside the drum 31. When the drum 31 rotates clockwise, the spiral blades 35 can transport the Salvia miltiorrhiza to the bottom of the drum 31, that is, the end near the drive device 33. The Salvia miltiorrhiza at the bottom of the drum 31 can tumble more violently under the action of the spiral blades 35, which is beneficial for shaking off mud and removing fibrous roots. It is worth noting that a buffer section 351 is provided at the end of the spiral blade 35 away from the inner wall of the drum 31. The buffer section 351 is arc-shaped, which can prevent the Salvia miltiorrhiza from directly hitting the end of the spiral blade 35 during tumbling, thus preventing breakage. When the drum 31 rotates counterclockwise, the spiral blades 35 can transport the Salvia miltiorrhiza to the opening of the drum 31 and allow it to fall out.

[0040] The lifting frame 32 in this embodiment includes a support 321, a set of fixed support legs 322, and a set of lifting support legs 323. A roller 31 is rotatably mounted on the support 321. The lifting support legs 323 are hinged to the lower end of the support 321 near the opening of the roller 31, and the fixed support legs 322 are hinged to the lower end of the support 321 away from the opening of the roller 31. The lifting support legs 323 in this embodiment include an outer sleeve and an inner sleeve that are fitted together. The outer sleeve and the inner sleeve are connected by an electric cylinder or a hydraulic cylinder to drive the extension and retraction of the lifting support legs 323.

[0041] The guide groove 34 is crescent-shaped. One end of the crescent-shaped guide groove 34 corresponds to the transfer basket 7, and the other end is equipped with a baffle to prevent the salvia miltiorrhiza from falling.

[0042] like Figure 5-6 As shown, the humidification device 4 includes a humidification box 41, with a steam inlet 42 at the bottom. Water vapor can enter the humidification box 41 through a pipe. Humidification grids 43 are fixed at intervals inside the humidification box 41, and there is space for water vapor to flow between the inner wall of the humidification box 41 and the humidification grids 43. The transfer basket 7 containing the cleaned and shaped Salvia miltiorrhiza can be placed inside the humidification box 41 for humidification. Preferably, during the humidification process, the top of the humidification box 41 is covered with cotton cloth to reduce the rate of water vapor loss and to maintain the temperature inside the humidification box 41.

[0043] like Figure 7 As shown, the slicing device 5 includes a sorting table 51. One end of the sorting table 51 is provided with a conveying trough 52 capable of holding a single piece of Salvia miltiorrhiza. There are multiple conveying troughs 52 arranged side by side. The end of the sorting table 51 is provided with a cutting assembly 53, which can cut the Salvia miltiorrhiza conveyed from the conveying trough 52 into slices. The end of the sorting table 51 with the cutting assembly 53 is connected to a conveyor table 54. The sliced ​​Salvia miltiorrhiza can be conveyed by the conveyor table 54 and fall into the transfer basket 7 for temporary storage.

[0044] At the other end of the sorting table 51 is the Salvia miltiorrhiza temporary storage table 55. After being moistened, the Salvia miltiorrhiza can be poured onto the Salvia miltiorrhiza temporary storage table 55, and then sorted by workers and placed in the conveying trough 52. The edge of the Salvia miltiorrhiza temporary storage table 55 is provided with an inclined shielding part 551, which can prevent the Salvia miltiorrhiza from falling. At the same time, the inclined shielding part 551 also facilitates the removal of the remaining impurities, fibrous roots, and small or deteriorated Salvia miltiorrhiza from the Salvia miltiorrhiza temporary storage table 55 after sorting.

[0045] The cutting assembly 53 includes a gantry 531, on which a pressing assembly 532 is provided. The pressing assembly 532 can press the conveyed Salvia miltiorrhiza. A cutting blade that can move up and down repeatedly is provided on the side of the gantry 531 away from the sorting table 51. The cutting blade can slice the Salvia miltiorrhiza pressed on the gantry 531.

[0046] like Figure 8-13 As shown, the kang drying device 6 includes a kang 61 and a combustion chamber 62. A horizontal smoke baffle 611 is installed at the middle position of the vertical direction inside the kang 61, dividing the interior of the kang 61 into an upper smoke circulation zone 612 and a lower smoke circulation zone 613. The upper smoke circulation zone 612 and the lower smoke circulation zone 613 are respectively provided with a smoke exhaust port 614 and a smoke inlet 615 on the same side. A smoke channel 616 is provided at the end of the horizontal smoke baffle 611 away from the smoke exhaust port 614 and the smoke inlet 615 to connect the upper smoke circulation zone 612 and the lower smoke circulation zone 613. The smoke circulation zone 613; the combustion chamber 62 includes a combustion zone 621 and a smoke exhaust zone 622. The combustion zone 621 is connected to the smoke inlet 615, and the smoke exhaust zone 622 is connected to the smoke exhaust outlet 614. The combustion zone 621 can burn fuels such as firewood to produce high-temperature smoke. The high-temperature smoke enters the lower smoke circulation zone 613 through the smoke inlet 615, then enters the upper smoke circulation zone 612, and finally enters the smoke exhaust zone 622 through the smoke exhaust outlet 614. The top of the smoke exhaust zone 622 is connected to the smoke exhaust pipe, which can discharge the smoke to the outside of the Salvia miltiorrhiza treatment plant.

[0047] Specifically, in this embodiment, the side of the earthen bed 61 closest to the combustion chamber 62 is defined as the front side, and the side of the earthen bed 61 furthest from the combustion chamber 62 is defined as the rear side. Since the flue gas first flows from the front side of the lower smoke circulation zone 613 to the rear side, and then flows from the rear side of the upper smoke circulation zone 612 to the front side, the uniformity of the temperature on the front and rear sides of the earthen bed 61 is effectively improved, and the temperature difference between the front and rear sides of the earthen bed 61 is reduced.

[0048] Preferred, such as Figure 9 and Figure 11 As shown, in order to further improve the overall temperature uniformity of the kang surface 65 of the earthen kang 61 and avoid the lower temperature on the left and right sides of the kang surface 65, the smoke channel 616 of the horizontal smoke baffle 611 in this embodiment is located at the middle position of the rear side. A diversion component 617 is provided at the middle position of the lower smoke circulation area 613. The diversion component 617 can divert the high-temperature smoke entering from the smoke inlet 615, so that the high-temperature smoke flows on the left and right sides and then enters the upper smoke circulation area 612 through the smoke channel 616 at the middle position of the rear side. An arc-shaped guide hood 618 is provided at the position of the upper smoke circulation area 612 near the smoke outlet 614. The guide hood 618 can allow the high-temperature smoke to enter the smoke outlet 614 from the left and right sides of the smoke outlet 614, so as to avoid the situation that the temperature in the middle of the kang surface 65 of the earthen kang 61 is too high, thereby further improving the overall temperature uniformity of the kang surface 65 of the earthen kang 61.

[0049] like Figure 13 As shown, in this embodiment, a heat-conducting seat 63 is provided at the top of the upper smoke circulation zone 612, and fins 631 are provided on the heat-conducting seat 63. Soil 64 is evenly spread above the heat-conducting seat 63, and the fins 631 are inserted into the soil 64 to form a kang surface 65. The kang surface 65 configured in this way has good thermal conductivity, heats up faster, and also further improves the overall temperature uniformity of the kang surface 65.

[0050] like Figure 8 As shown, the combustion zone 621 in this embodiment includes a bottom placement grille 623 and is surrounded by heat insulation plates on the left and right sides and the top surface. A ventilation zone is provided below the placement grille 623, which provides oxygen to the combustion zone 621 to promote combustion. Preferably, the ventilation zone is connected to a fan, which increases the oxygen content in the combustion zone 621, thereby accelerating the generation of high-temperature flue gas. It is worth noting that the combustion zone 621 also includes a furnace door 624 that can be opened and closed. Closing the furnace door 624 can prevent the leakage of high-temperature smoke.

[0051] Preferably, in this embodiment, an ash discharge drawer 625 is inserted into the ventilation zone, and the ash discharge drawer 625 can receive the ash produced by the combustion zone 621.

[0052] It is worth noting that a placement rack 66 is provided above the kang surface 65. The placement rack 66 can hold the transfer basket 7, so that the dried danshen slices can be directly put into the transfer basket 7, preventing the danshen slices from falling to the ground when loading the basket. Preferably, the placement rack 66 is evenly distributed with multiple connecting columns, and temperature sensors are installed on the connecting columns. The combustion cabinet 62 is equipped with a display screen, which can receive the detection signals from the temperature sensors and display the temperature of different positions on the kang surface 65 in real time. This setting can ensure that the temperature difference between different positions on the kang surface 65 is within a certain range, and can also detect whether there is any damage to the kang body 61, so as to carry out timely repairs.

[0053] In this embodiment, there are multiple drying devices 6 arranged side by side to improve the drying efficiency of Salvia miltiorrhiza. Drying Salvia miltiorrhiza using a drying method is low-cost, requiring only the burning of firewood and eliminating the need for electric heating, making it particularly suitable for rural areas. Furthermore, the temperature of the drying surface 65 is stable, and the surface of the earthen drying platform 61 also has a moisture-absorbing effect, further improving the drying efficiency of Salvia miltiorrhiza.

[0054] This utility model's centralized processing system for Salvia miltiorrhiza rationally arranges all the necessary equipment within the processing plant, achieving centralized processing of Salvia miltiorrhiza. This results in high processing efficiency and low overall system cost, making it suitable for construction in rural areas for cooperatives or Salvia miltiorrhiza production bases to centrally process large quantities of Salvia miltiorrhiza. The system achieves two-stage cleaning of Salvia miltiorrhiza through the installation of a pre-cleaning device and a impurity removal and shaping device, ensuring effective cleaning. After cleaning, the Salvia miltiorrhiza undergoes a humidification process in a device near the plant entrance, preventing water vapor from remaining in the plant and affecting the working environment. Simultaneously, multiple humidification and drying devices are arranged side-by-side. Since the humidification and drying processes are lengthy, this system avoids the problem of the system being unable to process Salvia miltiorrhiza due to the occupation or damage of a single humidification or drying device, ensuring continuous processing, good system stability, higher efficiency, and consistent quality of the processed Salvia miltiorrhiza.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 spirit and scope of the technical solutions of the embodiments of this utility model.
