Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wastewater treatment technology, specifically to a wastewater treatment device for medical device cleaning. Background Technology

[0002] Wastewater treatment during medical device cleaning is a crucial step, especially in hospitals and medical institutions. If the wastewater generated from cleaning medical devices is not effectively treated, it will not only pollute the environment but may also pose a threat to human health.

[0003] Patent publication number CN219991350U relates to a wastewater treatment device for medical device cleaning. The device includes a wastewater treatment tank with symmetrically arranged adsorption plates at the top. Ultraviolet lamps are arranged around the inner walls of the tank, and a filter screen is positioned directly below the lamps. A slider is located on the side of the filter screen. Sliding grooves are symmetrically formed on the inner walls of the tank. A handle is located on the front of the tank, connected to the filter screen. A flow guide platform is located at the bottom of the tank. A first purification layer is positioned directly below the filter screen, and a second purification layer is positioned directly below the first purification layer, located between the flow guide platform. An ozone generator and a drain pipe are located on one side of the bottom of the tank. A dosing structure is located on the side of the tank. This device has a simple structure, is easy to operate, has low cost, does not require a large space, and provides multi-layered purification, sterilization, and disinfection of medical wastewater, meeting discharge standards and protecting the environment.

[0004] In the aforementioned patent, ultraviolet lamps are installed around the inner wall of the wastewater treatment tank, with a filter screen located directly below the ultraviolet lamps. The structure is simple, easy to operate, and low in cost, requiring minimal space. It performs multi-layer purification, sterilization, and disinfection of medical wastewater. However, when dealing with tissue residues and fibers in medical device cleaning wastewater, large particles can easily clog the filter components, affecting the equipment's operating performance and efficiency. This also increases the difficulty of subsequent wastewater sedimentation treatment. Therefore, a medical device cleaning wastewater treatment device with better wastewater treatment performance is designed. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a medical device cleaning wastewater treatment device, which solves the technical problem in the prior art that when dealing with tissue residues and fibers in medical device cleaning wastewater, large particles of residue can easily cause clogging of the filter components, thereby affecting the operating effect and efficiency of the equipment, and also affecting the difficulty of subsequent sewage sedimentation treatment.

[0006] According to one aspect, at least one embodiment of the present invention provides a medical device cleaning wastewater treatment device, including a wastewater treatment tank. The surface of the wastewater treatment tank is provided with a wastewater treatment device for treating medical wastewater. The wastewater treatment device includes an inlet pipe that slidably penetrates the surface of the wastewater treatment tank. A threaded main shaft rotatably penetrates the surface of the wastewater treatment tank, and a reciprocating screw rotatably penetrates the surface of the wastewater treatment tank. A threaded conveying pipe is fixedly installed on the inner wall of the wastewater treatment tank. A fragmentation tube is rotatably installed on the circumferential surface of the threaded conveying pipe. A cutting blade is fixedly installed on the inner wall of the fragmentation tube. A contact wheel is fixedly installed on the circumferential surface of the reciprocating screw. An eccentric wheel is fixedly installed on the circumferential surface of the threaded main shaft. A contact block is slidably installed on the inner wall of the wastewater treatment tank. A telescopic spring rod is fixedly installed on the inner wall of the wastewater treatment tank. The cutting blade rotates to chop up small impurities inside the fragmentation tube, while large impurities and tissue residues are conveyed to the outside through the threaded main shaft until discharged, achieving graded separation of coarse filtration followed by fine treatment.

[0007] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: a threaded spindle with one end near the inlet pipe connected to the motor output end, and a transmission belt connecting the reciprocating screw and the threaded spindle. This not only prevents large impurities from entering the subsequent wastewater treatment chamber or pipe and causing blockage, but also breaks down small impurities into smaller particles, reducing their stability in the wastewater and creating better conditions for subsequent filtration, chemical treatment and other processes.

[0008] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: a contact wheel in contact with a fragmentation pipe, the contact block being fixedly connected to the bottom of the inlet pipe, the threaded conveying pipe being made of a water-filtering material, and the reciprocating motion of the inlet pipe improving the smoothness of feeding and the permeability of wastewater, avoiding blockage or adhesion to the pipe wall of the inlet pipe, thereby affecting the normal operation of the equipment.

[0009] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: an arc surface for contact and compression by an eccentric wheel on the inner wall of the contact block; the free end of the telescopic spring rod is fixedly connected to the contact block; and the wastewater is filtered into the interior of the fragment tube through a threaded conveying pipe.

[0010] According to another aspect, at least one embodiment of the present invention also provides a medical device cleaning wastewater treatment device. The inner wall of the wastewater treatment tank is provided with a filtration device for further filtration of the pre-treated wastewater. The filtration device includes an inclined filter plate, which is fixedly installed on the inner wall of the wastewater treatment tank. A drain pipe is fixedly inserted through the surface of the wastewater treatment tank. A sliding connecting plate is slidably installed on the circumferential surface of the reciprocating screw. A scraper plate is fixedly installed at the bottom of the sliding connecting plate. A connecting rod is fixedly inserted through the free end of the scraper plate. An inclined block is fixedly installed on the surface of the connecting rod. An inclined rod is fixedly installed on the inner wall of the wastewater treatment tank. The wastewater undergoes multiple filtration processes through the scraper plate to further purify the wastewater. Compared with single filtration, this design can reduce the concentration of suspended solids in the wastewater to a lower level.

[0011] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: a sliding connecting plate and a reciprocating screw connected by threads; the free end of the scraper plate is in contact with the surface of the inclined filter plate; the number of scraper plates is three; and the surface of the inclined block is provided with an inclined surface for assisting the inclined rod in bearing force, so as to avoid the filtration speed from decreasing and the filtration pressure from increasing due to pore blockage of the inclined filter plate.

[0012] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: fine filter holes on the surface of the inclined filter plate, coarse filter holes on the surface of the scraper filter plate, the length of the free ends of the three scraper filter plates gradually decreasing from the inlet pipe to the inclined rod one, and an inclined surface two for contacting and squeezing the inclined block one to move upward at the end of the inclined rod one away from the wastewater treatment tank. Small particulate impurities flow down or slide off under the action of wastewater, preventing the scraper filter plate from moving and accumulating impurities at the end of the inclined filter plate near the inclined rod one, thereby affecting the normal operation of the inclined filter plate. At the same time, it prevents impurities from accumulating at the feed end of the inclined filter plate for a long time, which can easily lead to wastewater overflow or filtration path deviation.

[0013] According to another aspect, at least one embodiment of the present invention also provides a medical device cleaning wastewater treatment device. The inner wall of the wastewater treatment tank is provided with an auxiliary treatment device for assisting the wastewater treatment tank in wastewater treatment. The auxiliary treatment device includes a sliding plate that slides through the surface of the wastewater treatment tank. A clearing block is fixedly installed on the surface of the sliding plate. A linkage rod is rotatably installed on the surface of the sliding plate. A connecting ring is rotatably installed on the fragmentation pipe. A medicine tank is fixedly installed on the surface of the wastewater treatment tank. A second inclined block is fixedly installed on the surface of the inlet pipe. A squeezing disc is slidably installed on the inner wall of the medicine tank. A second inclined rod is fixedly installed on the surface of the squeezing disc. A second telescopic spring rod is fixedly installed on the surface of the inlet pipe. The clearing block moves to unclog the wastewater treatment tank outlet, preventing blockage and thus affecting the efficiency of the equipment in treating wastewater. This could lead to an increase in the wastewater level inside the wastewater treatment tank, which in turn affects the drainage from the fragmentation pipe to the wastewater treatment tank, causing stagnation in the front-end treatment process.

[0014] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: a linkage rod at one end away from the sliding plate is rotatably connected to a sliding connecting plate; the connecting ring is connected to the fragmentation pipe; the surface of the second inclined block is provided with an inclined surface three for contacting and squeezing the second inclined rod to move away from the inlet pipe; the rotation of the fragmentation pipe drives the cutting blade to rotate to mix the medicine and wastewater; at the same time, the wastewater moves away from the inlet pipe, which sufficiently prolongs the mixing time of the medicine and wastewater.

[0015] For example, in a medical device cleaning wastewater treatment device provided in at least one embodiment of the present invention, the device further includes: a medicine tank fixedly penetrating the surface of a connecting ring, the second inclined rod fixedly penetrating the surface of the medicine tank, and the surface of the second inclined rod being provided with an inclined surface four for assisting the second inclined block to bear force, thereby further improving its effect and avoiding excessively high local concentration of medicine leading to equipment corrosion or insufficient treatment effect due to excessively low concentration.

[0016] The beneficial effects of the embodiments of the present invention are as follows: In this invention, large impurities and waste are isolated inside by a threaded conveying pipe, while wastewater is filtered into the interior of a fragmentation pipe through the threaded conveying pipe. The rotation of the contact wheel drives the fragmentation pipe to rotate, which in turn drives the cutting blade to rotate. The rotating cutting blade shreds the fine impurities inside the fragmentation pipe, while large impurities and tissue residues are conveyed to the outside and discharged through the threaded spindle. This achieves a graded separation of coarse filtration followed by fine treatment. On the one hand, it prevents large impurities from entering the subsequent wastewater treatment chamber or pipes and causing blockages. On the other hand, it shreds the fine impurities into smaller particles, reducing their stability in the wastewater and creating better conditions for subsequent filtration, chemical treatment, and other processes.

[0017] In this invention, the rotation of the threaded spindle drives the eccentric wheel to rotate. The rotation of the eccentric wheel contacts and squeezes the contact block to move upward. The upward movement of the contact block drives the water inlet pipe to move. At this time, the reciprocating motion of the water inlet pipe improves the smoothness of feeding and the passage of sewage, avoiding blockage or adhesion to the pipe wall, which would affect the normal operation of the equipment.

[0018] In this invention, the reciprocating screw rotates to drive the sliding connecting plate to move, and the sliding connecting plate moves the scraper plate. When sewage flows down through a section of the inclined rod, the sewage undergoes multiple filtration processes through the scraper plate to further purify the sewage. Compared to single filtration, this design can reduce the concentration of suspended solids in the sewage to a lower level. The movement of the scraper plate removes impurities that are attached to or clogging the surface of the inclined filter plate, thus preventing the filtration speed from decreasing and the filtration pressure from increasing due to pore blockage.

[0019] In this invention, when the sliding connecting plate moves under the action of the reciprocating screw, the movement of the connecting rod drives the first inclined block to move. Then the first inclined block moves until it contacts and moves upward under the action of the first inclined rod. At this time, small particulate impurities flow down or slide off under the action of sewage, avoiding the movement of the scraper plate and the accumulation of impurities on the end of the inclined filter plate near the first inclined rod, which would affect the normal operation of the inclined filter plate. At the same time, it avoids the long-term accumulation of impurities at the feed end of the inclined filter plate, which could easily lead to sewage overflow or filtration path deviation.

[0020] In this invention, the sliding plate moves to drive the unblocking block, which then clears the sewage treatment tank outlet, preventing blockage and ensuring the equipment's sewage treatment efficiency. Blockage can lead to an increase in the sewage level within the tank, which in turn affects the drainage from the fragmentation pipe, causing stagnation in the front-end treatment process. Meanwhile, the chemicals inside the chemical tank are forced into the connecting ring by the extrusion plate, and then enter the fragmentation pipe through the connecting ring. Simultaneously, the rotation of the fragmentation pipe drives the cutting blades to mix the chemicals and sewage. The sewage moves away from the inlet pipe, extending the mixing time and further improving the effect. This prevents excessively high local concentrations of chemicals from causing equipment corrosion or insufficient concentrations from resulting in inadequate treatment. Attached Figure Description

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-7 As shown, this invention illustrates a medical device cleaning wastewater treatment device according to an embodiment of the present invention. The device includes a wastewater treatment tank 1. The surface of the wastewater treatment tank 1 is provided with a wastewater treatment device for treating medical wastewater. The wastewater treatment device includes an inlet pipe 21 that slides through the surface of the wastewater treatment tank 1. A threaded spindle 22 rotatably passes through the surface of the wastewater treatment tank 1. A reciprocating screw 23 rotatably passes through the surface of the wastewater treatment tank 1. A threaded conveying pipe 24 is fixedly installed on the inner wall of the wastewater treatment tank 1. A fragmentation pipe 25 is rotatably installed on the circumferential surface of the threaded conveying pipe 24. A cutting blade 26 is fixedly installed on the inner wall of the fragmentation pipe 25. A contact wheel 27 is fixedly installed on the circumferential surface of the reciprocating screw 23. An eccentric wheel 31 is fixedly installed on the circumferential surface of the threaded spindle 22. A contact block 32 is slidably installed on the inner wall of the wastewater treatment tank 1. The rotation of the threaded spindle 22 drives the eccentric wheel 31 to rotate, causing the eccentric wheel 31 to contact and press the contact block 32 upwards. A telescopic spring rod 33 is fixedly installed on the inner wall of the wastewater treatment tank 1.

[0031] One end of the threaded spindle 22 near the water inlet pipe 21 is connected to the motor output end. A transmission belt is connected between the reciprocating screw 23 and the threaded spindle 22. The rotation of the threaded spindle 22 drives the transmission belt to rotate, the rotation of the transmission belt drives the reciprocating screw 23 to rotate, and the rotation of the reciprocating screw 23 drives the contact wheel 27 to rotate.

[0032] The contact wheel 27 contacts the fragmentation pipe 25, the contact block 32 is fixedly connected to the bottom of the water inlet pipe 21, the threaded conveying pipe 24 is made of water-filtering material, the threaded spindle 22 rotates to convey sewage away from the water inlet pipe 21, and at the same time, because the threaded conveying pipe 24 is made of water-filtering material, large impurities and waste are isolated inside the threaded conveying pipe 24.

[0033] The inner wall of the contact block 32 is provided with an arc surface for the eccentric wheel 31 to contact and squeeze. The free end of the telescopic spring rod 33 is fixedly connected to the contact block 32. When the contact block 32 moves upward, it drives the water inlet pipe 21 to move. At this time, the water inlet pipe 21 moves back and forth to improve the feeding flow and sewage passage.

[0034] In some examples, by starting the motor, the threaded spindle 22, with one end near the inlet pipe 21 connected to the motor output, rotates under the action of the motor output. At this time, the worker connects the sewage to the inlet pipe 21, and the sewage then enters the threaded conveying pipe 24 through the inlet pipe 21. The rotation of the threaded spindle 22 then transports the sewage away from the inlet pipe 21. Simultaneously, because the threaded conveying pipe 24 is made of a filter material, large impurities and waste are trapped inside, while the sewage is filtered into the fragmentation pipe 25. Simultaneously, the rotation of the threaded spindle 22 drives the drive belt to rotate, which in turn drives the reciprocating screw 23 to rotate. The reciprocating screw 23 then drives the contact wheel 27 to rotate. Since the contact wheel 27 is in contact with the fragmentation pipe 25, its rotation drives the fragmentation pipe 25 to rotate. The rotation of the fragmentation pipe 25, under the action of the contact wheel 27, drives the cutting blade 26 to rotate, which in turn breaks down the fragments. Fine impurities inside pipe 25 are shredded, while large impurities and tissue residues are transported to the outside and discharged through the threaded spindle 22. This achieves a graded separation of coarse filtration followed by fine treatment. On the one hand, it prevents large impurities from entering the subsequent wastewater treatment tank 1 or pipes and causing blockages. On the other hand, it shreds fine impurities into smaller particles, reducing their stability in the wastewater and creating better conditions for subsequent filtration, chemical treatment, and other processes. Subsequently, the wastewater inside the shredded pipe 25 is discharged into the wastewater treatment tank 1 at the end away from the inlet pipe 21 for further treatment. When the threaded spindle 22 rotates under the action of the motor output, the rotation of the threaded spindle 22 drives the eccentric wheel 31 to rotate. The rotation of the eccentric wheel 31 contacts and squeezes the contact block 32 to move upward. The upward movement of the contact block 32 drives the inlet pipe 21 to move. At this time, the reciprocating motion of the inlet pipe 21 improves the smoothness of feeding and the passage of wastewater, avoiding blockages or adhesions to the pipe wall of the inlet pipe 21, which would affect the normal operation of the equipment.

[0035] refer to Figures 1-7 In some embodiments, a medical device cleaning wastewater treatment device further includes a filtration device, including a filtration device for refining the pre-treated wastewater on the inner wall of the wastewater treatment tank 1. The filtration device includes an inclined filter plate 41, which is fixedly installed on the inner wall of the wastewater treatment tank 1. A drain pipe 42 is fixedly inserted through the surface of the wastewater treatment tank 1. A sliding connecting plate 43 is slidably installed on the circumferential surface of the reciprocating screw 23. A scraper plate 44 is fixedly installed at the bottom of the sliding connecting plate 43. A connecting rod 45 is fixedly inserted through the free end of the scraper plate 44. An inclined block 46 is fixedly installed on the surface of the connecting rod 45. An inclined rod 47 is fixedly installed on the inner wall of the wastewater treatment tank 1. The movement of the connecting rod 45 drives the inclined block 46 to move. Subsequently, the inclined block 46 moves until it contacts and moves upward under the action of the inclined rod 47.

[0036] The sliding connecting plate 43 is connected to the reciprocating screw 23 by a thread. The free end of the scraper plate 44 is in contact with the surface of the inclined filter plate 41. There are three scraper plates 44. The scraper plate 44 moves to be in contact with the surface of the inclined filter plate 41. The scraper plate 44 moves to scrape off the impurities that are attached to or block the surface of the inclined filter plate 41 or accumulated thereon. The surface of the inclined block 46 is provided with an inclined surface 47 to assist the inclined rod 47 in bearing the force.

[0037] The surface of the inclined filter plate 41 is provided with fine filter holes, and the surface of the scraped filter plate 44 is provided with coarse filter holes. The length of the free end of the three scraped filter plates 44 gradually decreases from the water inlet pipe 21 to the inclined rod 47. The end of the inclined rod 47 away from the sewage treatment tank 1 is provided with an inclined surface 2 for contacting and squeezing the inclined block 46 to move upward. When the sliding connecting plate 43 moves under the action of the reciprocating screw 23, the moving connecting rod 45 drives the inclined block 46 to move.

[0038] In this embodiment, to achieve a deep filtration effect, a filtration device is provided on a medical device cleaning wastewater treatment device. When the reciprocating screw 23 rotates under the action of the threaded spindle 22, since the reciprocating screw 23 and the sliding connecting plate 43 are connected by threads, the rotation of the reciprocating screw 23 drives the sliding connecting plate 43 to move, and the movement of the sliding connecting plate 43 drives the scraper plate 44 to move. When the wastewater flows down through the inclined rod 47, the wastewater undergoes multiple filtration treatments through the scraper plate 44, further purifying the wastewater. Compared with single filtration, this design can reduce the concentration of suspended solids in the wastewater to a lower level. At the same time, the movement of the scraper plate 44 makes it adhere to the surface of the inclined filter plate 41, and the movement of the scraper plate 44 removes impurities that are attached to or blocking the surface of the inclined filter plate 41 or are accumulated thereon. The scraping action prevents the inclined filter plate 41 from becoming clogged, which would cause a decrease in filtration speed and an increase in filtration pressure. At the same time, wastewater enters the interior of the inclined filter plate 41 through filtration and is then discharged through the drain pipe 42. When the sliding connecting plate 43 moves under the action of the reciprocating screw 23, the moving connecting rod 45 drives the inclined block 46 to move. The inclined block 46 then moves until it contacts and moves upward under the action of the inclined rod 47. At this time, small particles of impurities flow down or slide off under the action of the wastewater. This prevents the scraper plate 44 from moving and accumulating impurities at the end of the inclined filter plate 41 near the inclined rod 47, which would affect the normal operation of the inclined filter plate 41. It also prevents impurities from accumulating at the feed end of the inclined filter plate 41 for a long time, which could easily lead to wastewater overflow or filtration path deviation.

[0039] refer to Figures 1-7In some embodiments, a medical device cleaning wastewater treatment device further includes an auxiliary treatment device, including an auxiliary treatment device for assisting the wastewater treatment tank 1 in wastewater treatment, provided on the inner wall of the wastewater treatment tank 1. The auxiliary treatment device includes a sliding plate 51 that slides through the surface of the wastewater treatment tank 1. A block cleaning block 52 is fixedly installed on the surface of the sliding plate 51. A linkage rod 53 is rotatably installed on the surface of the sliding plate 51. A connecting ring 54 is rotatably installed on the fragmentation pipe 25. A medicine tank 55 is fixedly installed on the surface of the wastewater treatment tank 1. A second inclined block 56 is fixedly installed on the surface of the water inlet pipe 21. A squeezing disc 57 is slidably installed on the inner wall of the medicine tank 55. A second inclined rod 58 is fixedly installed on the surface of the squeezing disc 57. When the water inlet pipe 21 moves, it drives the second inclined block 56 to move. The second inclined block 56 moves to contact and squeeze the second inclined rod 58, moving it away from the water inlet pipe 21. At this time, the movement of the second inclined rod 58 drives the squeezing disc 57 to move. A second telescopic spring rod 59 is fixedly installed on the surface of the water inlet pipe 21.

[0040] The end of the linkage rod 53 away from the sliding plate 51 is rotatably connected to the sliding connecting plate 43. The connecting ring 54 is connected to the fragment tube 25. The surface of the second inclined block 56 is provided with an inclined surface 3 for contacting and squeezing the second inclined rod 58 to move away from the water inlet pipe 21. When the water inlet pipe 21 moves upward under the action of the eccentric wheel 31, the movement of the water inlet pipe 21 drives the second inclined block 56 to move. The movement of the second inclined block 56 contacts and squeezes the second inclined rod 58 to move away from the water inlet pipe 21.

[0041] The medicine canister 55 is fixedly inserted through the surface of the connecting ring 54. The medicine inside the medicine canister 55 is squeezed into the interior of the connecting ring 54 under the action of the extrusion disc 57. Then the medicine enters the interior of the fragment tube 25 through the connecting ring 54. The second inclined rod 58 is fixedly inserted through the surface of the medicine canister 55. The surface of the second inclined rod 58 is provided with an inclined surface four for the second inclined block 56 to receive force.

[0042] In this embodiment, to assist in wastewater treatment, an auxiliary treatment device is provided on a medical device cleaning wastewater treatment device. When the sliding connecting plate 43 moves under the action of the reciprocating screw 23, the sliding connecting plate 43 moves away from the sliding plate 51, causing the linkage rod 53 to rotate. The rotation of the linkage rod 53 causes the sliding plate 51 to move closer to the sliding connecting plate 43. The movement of the sliding plate 51 causes the unblocking block 52 to move. Subsequently, the unblocking block 52 moves to unclog the discharge port of the wastewater treatment tank 1, preventing the discharge port from becoming blocked and affecting the efficiency of the equipment in treating wastewater. This leads to an increase in the wastewater level in the wastewater treatment tank 1, which in turn affects the drainage from the fragmentation pipe 25 to the wastewater treatment tank 1, causing the front-end treatment stage to stagnate. When the inlet pipe 21 is in the eccentric wheel When the inlet pipe 21 moves upward under the action of 31, the movement of the inlet pipe 21 drives the movement of the inclined block 56. The inclined block 56 moves and contacts and squeezes the inclined rod 58, moving it away from the inlet pipe 21. At this time, the movement of the inclined rod 58 drives the squeezing disc 57 to move. Then the squeezing disc 57 moves and squeezes the agent inside the agent tank 55. Then the agent inside the agent tank 55 is squeezed into the interior of the connecting ring 54 under the action of the squeezing disc 57. Then the agent enters the interior of the fragmentation pipe 25 through the connecting ring 54. At the same time, the fragmentation pipe 25 rotates and drives the cutting blade 26 to rotate, mixing the agent and the sewage. Meanwhile, the sewage moves away from the inlet pipe 21, which fully prolongs the mixing time of the agent and the sewage, further improving its effect and avoiding excessively high local concentration of agent, which may cause equipment corrosion or insufficient treatment effect.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
