Description

Technical Field

[0001] This invention belongs to the field of kitchen waste sewage treatment technology, and specifically relates to an environmentally friendly sewage separation and treatment device for kitchen waste. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and catering services provided by institutions. When treating kitchen waste, it is necessary to separate liquid and solid waste. However, the kitchen waste wastewater after solid-liquid separation contains a large amount of oil. If it is discharged directly, it will cause pipe blockage and water pollution. Therefore, it is necessary to separate the oil and water in the kitchen waste wastewater before further treatment and discharge.

[0003] Existing oil-water separation equipment typically uses oil-absorbing sponges to absorb oil, but it cannot automatically switch between oil-absorbing sponges, resulting in frequent manual replacement of consumables during the oil absorption process, leading to low oil absorption efficiency and increased labor costs.

[0004] A search revealed that the prior art includes a patent document with publication number CN219567640U and publication date of August 22, 2023, which discloses a kitchen waste sewage processor. This processor facilitates solid-liquid separation of kitchen waste, improves dehydration efficiency, absorbs oil from sewage to enhance oil-water separation, and heats and sterilizes the sewage, improving safety and practicality. It includes a processing tank, a filter plate, and a feeding mechanism. The processing tank has a feed inlet at its top, and the feeding mechanism is installed at the feed inlet. The filter plate is installed inside the processing tank. The processor also includes an oil drain pipe, a drain pipe, valves, a dehydration mechanism, an oil removal mechanism, and a heating mechanism. The oil drain pipe and drain pipe are installed at the upper and lower ends of the right side wall of the static separation chamber of the processing tank, respectively, and both are equipped with valves. The dehydration mechanism is located inside the dehydration chamber of the processing tank and is installed on the outer wall of the processing tank. The oil removal mechanism is located inside the static separation chamber of the processing tank.

[0005] However, the device still has the following drawbacks: although the oil can be absorbed from the sewage in the middle of the static separation chamber by the oil-absorbing sponge, it cannot automatically switch the oil-absorbing sponge, which requires frequent manual replacement of consumables during the oil absorption process, resulting in low oil absorption efficiency and increased labor costs. Summary of the Invention

[0006] To address the above problems, the present invention provides an environmentally friendly wastewater separation and treatment device for kitchen waste, including a base, on which two sets of upright plates are fixedly connected, and a wastewater tank is provided between the two sets of upright plates;

[0007] The base is provided with a lifting mechanism, the lifting mechanism is driven to an oil suction guide mechanism, and the oil suction guide mechanism is driven to an oil-water separation component.

[0008] The oil suction guiding mechanism includes two sets of guide boxes. A second motor is installed in one set of guide boxes. A lead screw is driven to the output end of the second motor. An internal thread block is threaded to the lead screw. The internal thread block is fixedly connected to one end of the oil-water separation component. A guide plate is laid on the bottom of the inner wall of the guide box. Four sets of toothed plates are laid at equal intervals on the guide plate.

[0009] The oil-water separation component includes two sets of mounting shafts, each set of mounting shafts is rotatably connected to a ring gear, and the two sets of ring gears are intermittently meshed with four corresponding sets of toothed plates.

[0010] Furthermore, the meshing ratio between the ring gear and the gear plate is 1:4. A linkage ring is fixedly connected to one side of each of the two sets of ring gears. Four oil suction mechanisms are fixedly connected to the linkage ring. Each oil suction mechanism includes two sets of connecting plates. One end of each of the two sets of connecting plates is fixedly connected to the side wall of the two sets of linkage rings.

[0012] Furthermore, the oil storage mechanism includes two sets of baffles, the center of the side wall of each set of baffles is fixedly connected to two sets of mounting shafts, and a first snap-fit ​​groove is opened on the opposite side wall of each set of baffles. An oil storage tank is fixedly connected between the two sets of baffles. A liquid level sensor is installed inside the oil storage tank. An oil inlet groove is opened at the top of the oil storage tank. Two sets of arc-shaped guide plates and two sets of flow guide plates are fixedly connected to the oil storage tank. Both sets of arc-shaped guide plates and two sets of flow guide plates are located at the edge of the oil inlet groove.

[0013] Furthermore, the arc-shaped guide plate is arched, with its center bulging inward. Both ends of the arc-shaped guide plate are in contact with the inner sidewall of the baffle plate. The inner sidewall of the arc-shaped guide plate is provided with a second snap-fit ​​groove, and both ends of the second snap-fit ​​groove are connected to the first snap-fit ​​groove.

[0014] Furthermore, two sets of extrusion plates are sleeved on the sleeve shaft. The two sets of extrusion plates are respectively disposed at both ends of the oil-absorbing sponge and are movably engaged with the oil-absorbing sponge. An extension plate is fixedly connected to the extrusion plate, and a snap-fit ​​block is fixedly connected to the side wall of the extension plate.

[0015] Furthermore, a rotating sleeve is fixedly connected to one end of the sleeve shaft, and a connecting thread is provided at the other end of the sleeve shaft. An internal threaded sleeve is fixedly connected to a set of the connecting plates. The internal threaded sleeve is threadedly connected to one end of the sleeve shaft. Several sets of snap-fit ​​pins are distributed in a ring array on the side wall of the extrusion plate, and several sets of barbs are provided on the side wall of each snap-fit ​​pin.

[0016] Furthermore, the lifting mechanism includes two sets of transmission grooves, each containing a bidirectional threaded rod. Two sets of support blocks are threaded onto the bidirectional threaded rods, symmetrically distributed around the central axis of the bidirectional threaded rods. Each set of support blocks is rotatably connected to a linkage rod, the other end of which is rotatably connected to an oil suction guide mechanism. An L-shaped bracket is mounted on one set of the vertical plates, and a first motor is mounted on the L-shaped bracket.

[0018] Furthermore, the sewage tank is fixedly connected to the base, and a transparent observation window is provided on the side wall of the sewage tank. A conical funnel is fixedly connected to a set of the upright plates. The bottom end of the conical funnel is connected to a water inlet pipe. The outlet end of the water inlet pipe extends through the upright plate and into the sewage tank. A drain pipe is connected to the side wall of the sewage tank away from the water inlet pipe. Valves are provided on both the drain pipe and the water inlet pipe.

[0019] The beneficial effects of this invention are:

[0020] 1. The oil-water separation component moves laterally along the sewage tank via the oil-absorbing guide mechanism, ensuring that there are no dead corners for adsorbing floating oil. Through the meshing transmission of the ring gear and the toothed plate, the ring gear moves and rotates intermittently, allowing the oil-water separation component to move and adsorb oil along the sewage surface while the oil-absorbing sponge switches automatically intermittently. This improves the oil adsorption efficiency and avoids frequent manual replacement of consumables. It can continuously adsorb floating oil on the sewage surface without manual intervention, significantly improving the oil-water separation efficiency.

[0021] 2. When the oil-water separation component moves the oil-absorbing sponge and switches between oil-absorbing sponges, the oil-absorbing sponge rotates to the top of the oil storage tank. The engagement of the snap-fit ​​block and the arc-shaped guide plate drives the extrusion plate to compress the sponge, causing the oil absorbed by the sponge to drip into the oil storage tank through the oil inlet groove for storage. This effectively prevents the sponge from becoming saturated and failing. As the oil-absorbing sponge continues to rotate and switch, the two sets of snap-fit ​​blocks slide into the two sets of second snap-fit ​​grooves and move into the two sets of first snap-fit ​​grooves. This causes the two sets of extrusion plates to move synchronously in opposite directions, stretching the oil-absorbing sponge after it has finished squeezing the oil. This allows the oil-absorbing sponge to continue the next round of oil absorption, thereby extending the service life of the oil-absorbing sponge and reducing the replacement frequency.

[0022] 3. The oil-water separation state can be observed in real time through the transparent observation window, which helps to adjust the adsorption depth. Through the coordinated action of the bidirectional threaded rod and the linkage rod, the height of the oil-absorbing sponge can be dynamically adjusted so that the bottom set of oil-absorbing sponges can adhere to the surface of the sewage and adsorb the oil floating on the surface of the sewage. It can adapt to the oil adsorption operation with different oil layer thicknesses, so as to make the oil adsorption more precise and efficient.

[0023] 4. By holding and rotating the rotating sleeve, the sleeve shaft is disengaged from the internal threaded sleeve. This allows for quick disassembly of the sleeve shaft, enabling the replacement of the oil-absorbing sponge. After fitting the oil-absorbing sponge onto the sleeve shaft and completing the installation, insert both ends of the oil-absorbing sponge into several sets of retaining pins for fixation. By setting several sets of barbs, the friction between the retaining pins and the oil-absorbing sponge is increased, making the compression plate more stable when squeezing and stretching the oil-absorbing sponge, and preventing the compression plate from detaching from the oil-absorbing sponge.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides an environmentally friendly wastewater separation and treatment device for kitchen waste, including a base 100; for example, such as... Figures 1-3 As shown.

[0036] Two sets of upright plates 200 are fixedly connected to the base 100. A sewage tank 300 is provided between the two sets of upright plates 200. The sewage tank 300 is fixedly connected to the base 100. A transparent observation window 310 is provided on the side wall of the sewage tank 300. A conical funnel 600 is fixedly connected to one set of upright plates 200. The bottom end of the conical funnel 600 is connected to a water inlet pipe 610. The liquid outlet end of the water inlet pipe 610 passes through the upright plate 200 and extends into the sewage tank 300. A drain pipe 800 is connected to the side wall of the sewage tank 300 away from the water inlet pipe 610. Valves are provided on both the drain pipe 800 and the water inlet pipe 610.

[0037] The base 100 is provided with a lifting mechanism 400, the lifting mechanism 400 is connected to an oil suction guide mechanism 500, and the oil suction guide mechanism 500 is connected to an oil-water separation component 700.

[0038] Specifically, wastewater from kitchen waste is introduced into a wastewater tank 300 through a conical funnel 600 via an inlet pipe 610 and allowed to settle, causing oil in the wastewater to float to the surface. The oil-water separation can be observed in real time through a transparent observation window 310. The height of the oil-absorbing guide mechanism 500 is adjusted by a lifting mechanism 400 so that the oil-water separation component 700 can absorb and collect the oil floating on the wastewater surface. The oil-absorbing guide mechanism 500 moves the oil-water separation component 700 to fully collect the oil floating on the wastewater surface. After oil-water separation, the wastewater is discharged through a drain pipe 800 for further treatment.

[0039] The lifting mechanism 400 includes two sets of transmission grooves 410. A bidirectional threaded rod 420 is rotatably connected in the transmission groove 410. Two sets of support blocks 430 are threadedly connected to the bidirectional threaded rod 420. The two sets of support blocks 430 are symmetrically distributed with the central axis of the bidirectional threaded rod 420 as the center. A linkage rod 440 is rotatably connected to each set of support blocks 430. The other end of the linkage rod 440 is rotatably connected to the oil suction guide mechanism 500. An L-shaped bracket 450 is installed on one set of vertical plates 200. A first motor 460 is installed on the L-shaped bracket 450. Two sets of synchronous pulleys 470 are rotatably connected to one set of vertical plates 200. A synchronous belt is sleeved on each set of synchronous pulleys 470. The center of one set of synchronous pulleys 470 is connected to the output end of the first motor 460. The centers of the two sets of synchronous pulleys 470 are respectively fixedly connected to one end of each set of bidirectional threaded rods 420.

[0040] Specifically, the first motor 460 drives a set of synchronous pulleys 470 to rotate, which in turn drives two sets of bidirectional threaded rods 420 to rotate synchronously. This causes the two sets of support blocks 430 to move synchronously in opposite or relative directions. Through the support of the two sets of linkage rods 440 on the oil suction guide mechanism 500, when the two sets of support blocks 430 move in opposite directions, the oil suction guide mechanism 500 moves downward; when the two sets of support blocks move in opposite directions, the oil suction guide mechanism 500 moves upward, thereby achieving the adjustment of the height of the oil suction guide mechanism 500.

[0041] The oil suction guiding mechanism 500 includes two sets of guide boxes 510. The bottom end of the guide box 510 is rotatably connected to two sets of linkage rods 440. Both ends of the guide box 510 are fixedly connected to limit blocks 520. Limit grooves 210 are opened on both sets of vertical plates 200. The two sets of limit blocks 520 pass through the corresponding set of limit grooves 210 and are movably fitted with the vertical plate 200.

[0042] Specifically, the guide box 510 is moved up and down by two sets of linkage rods 440, and the guide box 510 is more stable during the up and down movement by two sets of limit blocks 520 and limit grooves 210.

[0043] A second motor 530 is installed inside one set of guide boxes 510. The output end of the second motor 530 is connected to a lead screw 540. An internal thread block 550 is threaded onto the lead screw 540. A positioning shaft 560 is fixedly connected inside another set of guide boxes 510. A slider 570 is slidably connected onto the positioning shaft 560. The slider 570 and the internal thread block 550 are respectively fixedly connected to both ends of the oil-water separation component 700. A guide plate 580 is laid on the bottom of the inner wall of the guide box 510. Four sets of toothed plates 590 are laid at equal intervals on the guide plate 580.

[0044] Specifically, the second motor 530 drives the lead screw 540 to rotate, which causes the internal thread block 550 to move the oil-water separation component 700. The slider 570 is slidably connected to the positioning shaft 560, making the movement of the oil-water separation component 700 more stable.

[0045] For example, such as Figure 4 and Figure 5 As shown.

[0046] The oil-water separation component 700 includes two sets of mounting shafts 710. One end of each set of mounting shafts 710 is fixedly connected to an internal thread block 550 and a slider 570, respectively. An oil storage mechanism 720 is fixedly connected between the two sets of mounting shafts 710. A ring gear 730 is rotatably connected to each set of mounting shafts 710. The two sets of ring gears 730 are intermittently meshed with four corresponding sets of toothed plates 590. The meshing ratio between the ring gears 730 and the toothed plates 590 is 1:4. A linkage ring 740 is fixedly connected to one side of each set of ring gears 730. Four sets of oil suction mechanisms 750 are fixedly connected to the linkage ring 740.

[0047] The oil absorption mechanism 750 includes two sets of connecting plates 751. One end of each set of connecting plates 751 is fixedly connected to the side wall of two sets of linkage rings 740. A sleeve shaft 752 is detachably installed between the two sets of connecting plates 751. An oil-absorbing sponge 754 is movably engaged on the sleeve shaft 752.

[0048] Specifically, by adjusting the height of the oil-water separation component 700, the lowest set of oil-absorbing sponges 754 are brought into contact with the sewage surface to absorb the oil floating on the sewage surface. The oil-water separation component 700 is moved by the internal thread block 550, causing the oil-absorbing sponges 754 to move and absorb the oil on the sewage surface. When the ring gear 730 moves to the meshing position with a set of toothed plates 590, the ring gear 730 rotates while moving. Since the meshing ratio between the ring gear 730 and the toothed plates 590 is 1:4, the oil suction mechanism 750 rotates 90° every time it moves to the meshing position of the toothed plates 590, causing the next set of oil-absorbing sponges 754 to rotate directly below to continue absorbing oil. The oil-water separation component 700 moves along the sewage surface to absorb oil while intermittently and automatically switching the oil-absorbing sponges 754, improving the oil absorption efficiency while avoiding frequent manual replacement of consumables.

[0049] For example, such as Figure 6 and Figure 7 As shown.

[0050] The oil storage mechanism 720 includes two sets of baffles 721. The center of the side wall of each set of baffles 721 is fixedly connected to two sets of mounting shafts 710. Each side wall of the two sets of baffles 721 has a first snap-fit ​​groove 722. An oil storage tank 723 is fixedly connected between the two sets of baffles 721. A liquid level sensor is installed inside the oil storage tank 723. An oil inlet groove 724 is opened at the top of the oil storage tank 723. Two sets of arc-shaped guide plates 725 and two sets of flow guide plates 727 are fixedly connected to the oil storage tank 723. The two sets of arc-shaped guide plates 725 and two sets of flow guide plates 727 are all located at the edge of the oil inlet groove 724.

[0051] The arc-shaped guide plate 725 is arched, with the center of the arc-shaped guide plate 725 protruding inward. Both ends of the arc-shaped guide plate 725 are in contact with the inner sidewall of the baffle plate 721. The inner sidewall of the arc-shaped guide plate 725 is provided with a second snap-fit ​​groove 726, and both ends of the second snap-fit ​​groove 726 are connected to the first snap-fit ​​groove 722.

[0052] Two sets of extrusion plates 753 are sleeved on the sleeve shaft 752. The two sets of extrusion plates 753 are respectively disposed at both ends of the oil-absorbing sponge 754 and are movably engaged with the oil-absorbing sponge 754. An extension plate 7531 is fixedly connected to the extrusion plate 753. A snap-fit ​​block 7532 is fixedly connected to the side wall of the extension plate 7531. The snap-fit ​​block 7532 is slidably engaged with the first snap-fit ​​groove 722 and the second snap-fit ​​groove 726.

[0053] Specifically, when the oil-water separation component 700 moves to absorb oil and switches the oil-absorbing sponges 754, one set of oil-absorbing sponges 754 rotates from the side of the oil storage tank 723 to the bottom of the oil storage tank 723 to absorb oil, while the other set of oil-absorbing sponges 754 rotates from the side of the oil storage tank 723 to the top of the oil storage tank 723. During the rotation of the oil-absorbing sponges 754 driven by the sleeve shaft 752, the two sets of snap-fit ​​blocks 7532 slide in the two sets of first snap-fit ​​grooves 722 respectively, and move into the two sets of second snap-fit ​​grooves 726, so that the two sets of extrusion plates 753 move synchronously in opposite directions to extrude oil-absorbing sponges 754. The oil absorbed by the oil-absorbing sponges 754 drips into the oil storage tank 723 through the oil inlet groove 724 for storage. The oil level in the oil storage tank 723 is detected by the liquid level sensor. When the oil level reaches the preset value, the oil is sucked out by the oil suction machine for further processing to prevent the oil from overflowing.

[0054] Furthermore, as the oil-absorbing sponge 754 continues to rotate and switch, the two sets of snap-fit ​​blocks 7532 slide in the two sets of second snap-fit ​​grooves 726 respectively, and move into the two sets of first snap-fit ​​grooves 722, so that the two sets of extrusion plates 753 move synchronously in opposite directions, stretching the oil-absorbing sponge 754 after the oil is squeezed out, so that the oil-absorbing sponge 754 can continue to perform the next round of oil absorption operation.

[0055] For example, such as Figure 8 As shown.

[0056] One end of the sleeve shaft 752 is fixedly connected to a rotating sleeve 7521, and the other end of the sleeve shaft 752 is provided with a connecting thread 7522. An internal threaded sleeve 755 is fixedly connected to a set of connecting plates 751, and the internal threaded sleeve 755 is threadedly connected to one end of the sleeve shaft 752.

[0057] Specifically, by holding and rotating the rotating sleeve 7521, the sleeve shaft 752 is disengaged from the internal threaded sleeve 755, allowing for quick disassembly of the sleeve shaft 752 and replacement of the oil-absorbing sponge 754.

[0058] The sidewall of the extrusion plate 753 is arranged in a ring array with several sets of locking pins 7533, and the sidewall of each locking pin 7533 is provided with several sets of barbs 7534.

[0059] Specifically, after fitting the oil-absorbing sponge 754 onto the connecting shaft 752 and completing the installation of the connecting shaft 752, the two ends of the oil-absorbing sponge 754 are respectively inserted into several sets of retaining pins 7533 for fixation. By setting several sets of barbs 7534, the friction between the retaining pins 7533 and the oil-absorbing sponge 754 is increased, making the compression plate 753 more stable when compressing and stretching the oil-absorbing sponge 754, and preventing the compression plate 753 from detaching from the oil-absorbing sponge 754.

[0060] The working principle of the wastewater separation and treatment device for kitchen waste proposed in this invention is as follows:

[0061] Wastewater from kitchen waste is introduced into a wastewater tank 300 through a conical funnel 600 and inlet pipe 610 for settling. This allows oil in the wastewater to float to the surface. The oil-water separation can be observed in real time through a transparent observation window 310. The height of the oil-absorbing guide mechanism 500 is adjusted by a lifting mechanism 400 so that the oil-water separation component 700 can absorb and collect the oil floating on the wastewater surface. The oil-absorbing guide mechanism 500 moves the oil-water separation component 700 to fully collect the oil floating on the wastewater surface. After oil-water separation, the wastewater is discharged through a drain pipe 800 for further treatment.

[0062] The first motor 460 drives a set of synchronous pulleys 470 to rotate, which in turn drives two sets of bidirectional threaded rods 420 to rotate synchronously. This causes the two sets of support blocks 430 to move synchronously in opposite or relative directions. Through the support of the two sets of linkage rods 440 on the oil suction guide mechanism 500, when the two sets of support blocks 430 move in opposite directions, the oil suction guide mechanism 500 moves downward; when the two sets of support blocks move in opposite directions, the oil suction guide mechanism 500 moves upward, thereby achieving the adjustment of the height of the oil suction guide mechanism 500.

[0063] Two sets of linkage rods 440 drive the guide box 510 to move up and down. Two sets of limit blocks 520 are in contact with the limit groove 210 to make the guide box 510 more stable during the up and down movement. The second motor 530 drives the lead screw 540 to rotate, which causes the internal thread block 550 to move the oil-water separation component 700. The slider 570 is slidably connected to the positioning shaft 560 to make the oil-water separation component 700 more stable during the movement.

[0064] By adjusting the height of the oil-water separation component 700, the lowest set of oil-absorbing sponges 754 are made to adhere to the surface of the sewage, adsorbing the oil floating on the surface. The oil-water separation component 700 is moved by the internal threaded block 550, causing the oil-absorbing sponges 754 to move and adsorb the oil on the surface of the sewage. When the ring gear 730 moves to the meshing position with a set of toothed plates 590, the ring gear 730 rotates while moving, causing the next set of oil-absorbing sponges 754 to rotate to the bottom to continue adsorbing the oil. The oil-water separation component 700 moves along the surface of the sewage to adsorb the oil while intermittently and automatically switching the oil-absorbing sponges 754, improving the oil adsorption efficiency and avoiding frequent manual replacement of consumables.

[0065] When the oil-water separation component 700 moves to absorb oil and switches the oil-absorbing sponges 754, one set of oil-absorbing sponges 754 rotates from the side of the oil storage tank 723 to the bottom of the oil storage tank 723 to absorb oil, while the other set of oil-absorbing sponges 754 rotates from the side of the oil storage tank 723 to the top of the oil storage tank 723. During the rotation of the oil-absorbing sponges 754 driven by the sleeve shaft 752, the two sets of snap-fit ​​blocks 7532 slide in the two sets of first snap-fit ​​grooves 722 respectively, and move into the two sets of second snap-fit ​​grooves 726, so that the two sets of extrusion plates 753 move synchronously in opposite directions to extrude oil-absorbing sponges 754. The oil absorbed by the oil-absorbing sponges 754 drips into the oil storage tank 723 through the oil inlet groove 724 for storage. The oil level in the oil storage tank 723 is detected by the liquid level sensor. When the oil level reaches the preset value, the oil is sucked out by the oil suction machine for further processing to prevent the oil from overflowing.

[0066] As the oil-absorbing sponge 754 continues to rotate and switch, the two sets of snap-fit ​​blocks 7532 slide in the two sets of second snap-fit ​​grooves 726 respectively, and move into the two sets of first snap-fit ​​grooves 722, so that the two sets of extrusion plates 753 move synchronously in opposite directions, stretching the oil-absorbing sponge 754 after the oil is squeezed out, so that the oil-absorbing sponge 754 can continue to perform the next round of oil absorption operation.

[0067] By rotating the rotating sleeve 7521, the connecting shaft 752 is disengaged from the internal threaded sleeve 755, allowing for quick disassembly of the connecting shaft 752 and replacement of the oil-absorbing sponge 754. After fitting the oil-absorbing sponge 754 onto the connecting shaft 752 and completing the installation of the connecting shaft 752, both ends of the oil-absorbing sponge 754 are inserted into several sets of retaining pins 7533 for fixation. By setting several sets of barbs 7534, the friction between the retaining pins 7533 and the oil-absorbing sponge 754 is increased, making the compression plate 753 more stable when compressing and stretching the oil-absorbing sponge 754, and preventing the compression plate 753 from detaching from the oil-absorbing sponge 754.

[0068] Although the present invention 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; and these 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 the present invention.
