Description

Technical Field

[0001] The present invention belongs to the technical field of water and fertilizer machines, and particularly relates to an irrigation and fertilization integrated machine for landscaping and an irrigation and fertilization method. Background Art

[0002] The fertilization and irrigation integrated machine, as an outstanding product of modern agricultural technology, integrates the dual functions of irrigation and fertilization. The fertilization and irrigation integrated machine usually consists of multiple parts such as a cloud platform, a data acquisition terminal, a fertilizer applicator, a filtration system, a valve controller, an electromagnetic valve, and field pipelines. It can real-time monitor the moisture and nutrient status of the soil, and at the same time, combined with the fertilizer requirement characteristics of crop varieties, according to the irrigation and fertilization schemes preset by users, intelligently regulate key parameters such as irrigation volume, fertilizer absorption volume, fertilizer solution concentration, and pH value. Thus, the fertilization and irrigation integrated machine can achieve precise, timed, and quantitative control of the irrigation and fertilization processes, greatly improving the use efficiency of water and fertilizer, achieving the goals of water saving and fertilizer saving, and at the same time helping to improve the soil environment and enhance the overall quality of crops. In addition, the fertilization and irrigation integrated machine is widely used in various planting scenarios such as large fields, greenhouses, and gardens, and has multiple advantages such as labor saving, fertilizer saving, water saving, environmental protection, and soil protection.

[0003] Based on the above, although the fertilization and irrigation integrated machine has become an indispensable important tool in modern agriculture with its efficient and intelligent characteristics, there are still other problems to be solved. For example, when the fertilization and irrigation integrated machine pumps water, it may not be able to effectively remove impurities in the water source, such as suspended particles, organic matter, and microorganisms. Due to insufficient filtration accuracy, the impurities in the water are not completely removed, which may have a negative impact on the irrigation water quality, and thus cannot meet the high-standard irrigation quality requirements, reducing the expected effect of irrigation and fertilization. Summary of the Invention

[0004] The purpose of the present invention is to provide an irrigation and fertilization integrated machine for landscaping and an irrigation and fertilization method, which realize the synergistic effect of multi-stage filtration, enhance the filtration effect, ensure the smooth flow of water, avoid the occurrence of blockage phenomena, greatly improve the purity of water quality, avoid dripper blockage, and the inclined and bent design of the secondary filtration bypass pipe enables the water flow to generate a certain centrifugal force when passing through, which helps to throw impurities such as sand and gravel towards the pipe wall, further improving the filtration effect.

[0005] The technical solutions adopted by the present invention are specifically as follows:

[0006] An integrated irrigation and fertilization machine and an irrigation and fertilization method for landscaping, including a multi-stage filtration assembly. The top of the multi-stage filtration assembly is set as a water inlet, which is connected to a water source. The bottom of the multi-stage filtration assembly is set as a water outlet. After the water source passes through the multi-stage filtration of the multi-stage filtration assembly, it flows out from the water outlet; a connecting pipe and a fertilizer mixing barrel fixed to the connecting pipe through a union. The multi-stage filtration assembly is communicated with the fertilizer mixing barrel through the connecting pipe. After the water source passes through multi-stage filtration, it enters the interior of the fertilizer mixing barrel; an industrial water pump. One port of the industrial water pump is communicated with the fertilizer mixing barrel, and the other port is installed with a ball valve through a straight pipe, the ball valve; a fertilizer suction pipe. At least two paths of the fertilizer suction pipe are provided. One end of the fertilizer suction pipe is connected to the fertilizer mixing barrel, and the other end is connected to a water and fertilizer barrel. The fertilizer suction pipe is used to pump the fertilizer solution in the water and fertilizer barrel into the interior of the fertilizer mixing barrel; a control end, which is arranged on one side of the fertilizer mixing barrel.

[0007] In a preferred solution, the multi-stage filtration assembly includes a primary filtration pipe, and the primary filtration pipe is provided with a main channel vertically downward;

[0008] It further includes a secondary filtration bypass pipe. The secondary filtration bypass pipe is divided into an upper pipe and a lower pipe that are relatively upper and lower. The upper pipe and the lower pipe are both threadedly connected to the periphery of the primary filtration pipe, and there is a spacing for water flow between the upper pipe and the lower pipe, and they are communicated with the primary filtration pipe;

[0009] It further includes a tertiary filtration pipe, which is arranged below the primary filtration pipe and fixed to the connecting pipe. The water source passes through the primary filtration pipe, the secondary filtration bypass pipe, and the tertiary filtration pipe for step-by-step filtration and finally flows into the interior of the tertiary filtration pipe.

[0010] In a preferred solution, the bottom port position of the primary filtration pipe extends outward to form a boss, and a groove is opened at the top of the boss. The upper pipe is provided with a notch adapted to the boss, and a sealing rubber strip is installed in the notch. One side of the sealing rubber strip facing the groove is provided with a protruding pressing strip, and the sealing rubber strip and the pressing strip cooperate to seal and stop water.

[0011] In a preferred solution, a water stop plate is arranged at the position where the primary filtration pipe is connected to the lower pipe. The water stop plate is located below the lower pipe and extends along the inclined direction of the lower pipe. A vertical water intercepting plate is provided at the top of the water stop plate corresponding to the lower pipe, and the water intercepting plate is adaptively inserted into the lower pipe.

[0012] In a preferred solution, an upper water passing port is opened on the periphery of the primary filtration pipe corresponding to the position of the secondary filtration bypass pipe, and a lower water passing port is also opened below the upper water passing port on the primary filtration pipe. A fixing plate is arranged at the entity position between the upper water passing port and the lower water passing port. The middle of the fixing plate is concave, and a spring is fixed at its concave position. The top of the spring is fixed with a valve plate, and the valve plate moves up and down in the primary filtration pipe.

[0013] In a preferred embodiment, the secondary filtering bypass pipe inclines outward and then bends towards the primary filtering pipe, and is connected to the primary filtering pipe to form a bypass channel. An annular filter screen is arranged at the bending part inside the secondary filtering bypass pipe, and the annular filter screen is used for filtering sand and gravel.

[0014] In a preferred embodiment, a protruding annular platform is provided at the position inside the bending part in contact with the annular filter screen for supporting the annular filter screen.

[0015] In a preferred embodiment, a fixing ring is installed in the tertiary filtering pipe. An inner filter screen is installed at the bottom of the fixing ring, and an outer filter screen is provided outside the inner filter screen at the bottom of the fixing ring. A water filtering interlayer is arranged between the inner filter screen and the outer filter screen.

[0016] In a preferred embodiment, water permeable holes are formed at the bottom of the inner filter screen, and the bottom of the outer filter screen is closed.

[0017] An irrigation and fertilization method includes the following steps:

[0018] Step one: Ensure that all components are properly connected. At the same time, check whether the drip irrigation system is in good condition, without blockage or leakage. Based on the inspection results, prepare the fertilizer solution and input the fertilization parameters.

[0019] Step two: The control terminal remotely instructs the water pump to pump the fertilizer solution in the fertilizer and water bucket into the fertilizer mixing bucket through the fertilizer suction pipe.

[0020] Step three: Introduce water source into the multi-stage filtering assembly for multi-stage filtering, and then divert it to the inside of the fertilizer mixing bucket.

[0021] Step four: The control terminal automatically adjusts the mixing ratio of the fertilizer solution and clear water according to the input fertilization parameters, and then opens the ball valve. The fertilizer solution is led out through the industrial water pump to the drip irrigation system, and the fertilizer solution is transported to the drippers or drip irrigation tapes through the water distribution pipe network and slowly transported to the roots of the crops in a dripping manner.

[0022] Step five: The control terminal monitors the flow rate of the fertilizer and water in the pipeline in real time through the sensor, and automatically stops fertilization when the set fertilization amount is reached.

[0023] The technical effects achieved by the present invention are:

[0024] In the present invention, when the water flow impacts the valve plate and enters the upper water inlet, it is the primary filtration. This process mainly intercepts some long and light debris such as waterweeds and withered grass. The water body enters the secondary filtering bypass pipe by inertia or overflows from the lower water inlet to the main channel. Finally, the water flow that has been secondarily filtered in the secondary filtering bypass pipe also finally converges to the main channel and flows towards the tertiary filtering pipe.

[0025] In the present invention, when water flow enters the interior of the secondary filtration elbow pipe, it first enters the annular filter screen. The annular filter screen can intercept sand, gravel or other solid impurities in the water body, and can effectively capture those fine particles and impurities that were not intercepted by the primary filtration. Such a secondary filtration mechanism ensures that the water quality reaches a relatively high cleanliness level before mixing with fertilizer, avoiding causing a clogging burden to the drip irrigation system. The combination of the secondary filtration elbow pipe and the annular filter screen not only improves the filtration quality, but also ensures the smoothness of the water flow, reducing the resistance of the water flow. In addition, the inclined and bent design of the secondary filtration elbow pipe enables the water flow to generate a certain centrifugal force when passing through, which helps to throw impurities such as sand and gravel towards the pipe wall, further improving the filtration effect;

[0026] In the present invention, the water flow that directly overflows from the lower water inlet into the main channel, although bypassing the fine filtration of the secondary filtration elbow pipe, all the water flows that pass through the secondary filtration elbow pipe or directly come from the lower water inlet, after converging into the main channel, will flow towards the tertiary filtration pipeline for final fine treatment to ensure that the water quality output by the irrigation and fertilization integrated machine meets the requirements of landscaping. And the filter water interlayer helps to adsorb the floating suspended matters in the water quality, such as small particle impurities and some dissolved organic matters, further improving the clarity of the water quality. The coordinated action of the primary filtration pipeline, the secondary filtration elbow pipe and the tertiary filtration pipeline not only enhances the filtration effect, but also ensures the unobstructed water flow, avoiding the occurrence of clogging phenomena, and greatly improving the purity of the water quality.

[0045] Next, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0046] Please refer to the Figure 1-7 As shown, the present invention provides an integrated irrigation and fertilization machine and an irrigation and fertilization method for landscaping, including a multi-stage filtration assembly 1, a connecting pipe 2, a fertilizer mixing tank 3 fixed to the connecting pipe 2 through a union, an industrial water pump 4, a fertilizer suction pipe 6, and a control terminal 7. The top of the multi-stage filtration assembly 1 is provided with a water inlet 101, which is connected to a water source. The bottom of the multi-stage filtration assembly 1 is provided with a water outlet. After being multi-stage filtered by the multi-stage filtration assembly 1, the water source flows out from the water outlet. The multi-stage filtration assembly 1 is communicated with the fertilizer mixing tank 3 through the connecting pipe 2. After being multi-stage filtered, the water source enters the interior of the fertilizer mixing tank 3. One port of the industrial water pump 4 is communicated with the fertilizer mixing tank 3, and the other port is installed with a ball valve 5 through a straight pipe. The ball valve 5 is connected to a drip irrigation system. When the industrial water pump 4 operates, the water and fertilizer in the fertilizer mixing tank 3 are pumped out. The ball valve is opened, and drip irrigation is carried out on the landscaping through the drip irrigation system. Among them, the drip irrigation system includes a water distribution pipe network, drip emitters or drip irrigation tapes, etc., and slowly conveys the water and fertilizer to the roots of crops in a drip-by-drip manner through tiny pores. The drip irrigation system is composed of current existing technologies and will not be elaborated here. The fertilizer suction pipe 6 is provided with at least two paths. One end of the fertilizer suction pipe 6 is connected to the fertilizer mixing tank 3, and the other end is connected to a water and fertilizer tank. The fertilizer suction pipe 6 is used to pump the fertilizer solution in the water and fertilizer tank into the interior of the fertilizer mixing tank 3; the fertilizer solution in the fertilizer mixing tank 3 is proportioned and then mixed with clear water, and then the fertilizer solution in the fertilizer mixing tank 3 is pumped out by the industrial water pump 4. The control terminal 7 is arranged on one side of the fertilizer mixing tank 3.

[0047] Among them, the fertilizer intake amount of the fertilizer suction pipe 6, the water intake amount of the multi-stage filtration assembly 1, and the water outlet time of the industrial water pump 4 are controlled. It is worth mentioning that the control terminal 7 is programmed to control each component. In this application, the control terminal 7 still has control authority over the components not mentioned, and the above-mentioned components and control steps are preferentially described.

[0048] Please refer to again Figure 3-4, the multi-stage filtration assembly 1 includes a primary filtration pipeline 102. The primary filtration pipeline 102 is provided with a main channel 109 extending vertically downward. It also includes a secondary filtration elbow 103. The secondary filtration elbow 103 is divided into an upper pipe 1031 and a lower pipe 1032 that are opposite to each other up and down. Both the upper pipe 1031 and the lower pipe 1032 are threadedly connected to the periphery of the primary filtration pipeline 102, and there is a spacing for water flow between the upper pipe 1031 and the lower pipe 1032 and they communicate with the primary filtration pipeline 102. Among them, during installation, first, the lower pipe 1032 and the upper pipe 1031 are sequentially sleeved outside the primary filtration pipeline 102 and threadedly connected thereto. For the smooth threaded connection of the lower pipe 1032 and the upper pipe 1031 up and down, a table surface protruding outward is provided at the position where the primary filtration pipeline 102 is threadedly connected to the lower pipe 1032, so that the lower thread diameter of the primary filtration pipeline 102 is larger than the upper thread diameter, so that the upper pipe 1031 and the lower pipe 1032 can be smoothly threadedly sleeved on the primary filtration pipeline 102. It also includes a tertiary filtration pipeline 113. The tertiary filtration pipeline 113 is arranged below the primary filtration pipeline 102 and is fixed to the connecting pipeline 2. The water source is filtered step by step through the primary filtration pipeline 102, the secondary filtration elbow 103, and the tertiary filtration pipeline 113 and finally flows into the interior of the tertiary filtration pipeline 113.

[0049] Please refer to again Figure 4-5 , a boss 1021 extends outward from the bottom port position of the primary filtration pipeline 102. A groove 1022 is opened at the top of the boss 1021. The upper pipe 1031 is provided with a notch 1033 adapted to the boss 1021. A sealing rubber strip 1034 is installed in the notch 1033. A protruding pressing strip 1035 is provided on the side of the sealing rubber strip 1034 facing the groove 1022. The sealing rubber strip 1034 and the pressing strip 1035 cooperate to seal and prevent water leakage.

[0050] Based on the above, the double-threaded connection of the lower pipe 1032 and the upper pipe 1031, and water-stop components are provided at the positions of the connection joints. The groove 1022 is used to accommodate the pressing strip 1035 of the sealing rubber strip 1034 to ensure that the sealing rubber strip 1034 can fit tightly. The pressing strip 1035 and the groove 1022 cooperate to form a water-sealing structure, and through mechanical pressing or bolt fixing and other methods, the upper pipe 1031 and the primary filtration pipeline 102 are tightly connected to achieve the effect of airtight water-stop.

[0051] Please refer to again Figure 6-7 , a water-stop plate 8 is provided at the position where the primary filtration pipeline 102 is connected to the lower pipe 1032. The water-stop plate 8 is located below the lower pipe 1032 and extends along the inclined direction of the lower pipe 1032. A vertical water-blocking plate 9 is provided at the top of the water-stop plate 8 corresponding to the lower pipe 1032. The water-blocking plate 9 is adaptively inserted into the lower pipe 1032.

[0052] Specifically, the water stop plate 8 extends obliquely and is fixed to the tortuous channel 107, and the water intercepting plate 9 is adaptively inserted into the lower pipe 1032, further achieving a water stop effect and preventing leakage due to excessive water pressure.

[0053] More specifically, through the collaborative design of the sealing strip 1034, the pressing strip 1035, the water stop plate 8, and the water intercepting plate 9, an efficient airtight water stop effect is achieved at the connection between the primary filtration pipeline 102 and the upper pipe 1031 and the lower pipe 1032. This design structure can effectively prevent water flow leakage.

[0054] Please refer to again Figure 7-8 , an upper water inlet 104 is provided on the circumferential side of the primary filtration pipeline 102 corresponding to the position of the secondary filtration tortuous pipe 103. A lower water inlet 105 is also provided on the primary filtration pipeline 102 below the upper water inlet 104. A fixing plate 110 is provided at the solid position between the upper water inlet 104 and the lower water inlet 105. The middle of the fixing plate 110 is concave, and a spring 111 is fixed at its concave position. The top of the spring 111 is fixed with a valve plate 112, and the valve plate 112 moves up and down in the primary filtration pipeline 102.

[0055] Under normal conditions, the valve plate 112 is supported by the spring 111 and abuts against the neck of the primary filtration pipeline 102, and the inside of the primary filtration pipeline 102 is in a temporarily closed state. When the water flow impacts the valve plate 112, the valve plate 112 compresses the spring 111 and contracts, and the upper water inlet 104 and the lower water inlet 105 open, and the water flow enters the inside of the secondary filtration tortuous pipe 103 through the upper water inlet 104.

[0056] Based on the above structure, when the water flow impacts the valve plate 112 and enters the upper water inlet 104, it is primary filtration. This process mainly intercepts some long and light debris such as waterweeds and withered grass. The water body enters the secondary filtration tortuous pipe 103 by inertia or overflows into the main channel 109 from the lower water inlet 105. Finally, the water flow that has been secondarily filtered in the secondary filtration tortuous pipe 103 also finally converges into the main channel 109 and flows to the tertiary filtration pipeline 113.

[0057] Please refer to again Figure 7-8 , the secondary filtration tortuous pipe 103 is inclined outward and then bends towards the primary filtration pipeline 102 and is connected to the primary filtration pipeline 102 to form a tortuous channel 107. An annular filter screen 106 is provided at the bending part 108 in the secondary filtration tortuous pipe 103, and the annular filter screen 106 is used to filter sand and gravel.

[0058] Specifically, when water flows into the secondary filtering elbow pipe 103, it first enters the annular filter screen 106. The annular filter screen 103 can intercept sand, gravel or other solid impurities in the water body, and can effectively capture those fine particles and impurities that were not intercepted by the primary filtration. Such a secondary filtration mechanism ensures that the water quality reaches a relatively high cleanliness level before mixing with fertilizer, avoiding causing a blocking burden to the drip irrigation pipe. The combination of the secondary filtering elbow pipe 103 and the annular filter screen 106 not only improves the filtration quality but also ensures the smoothness of the water flow, reducing the resistance of the water flow. In addition, the inclined and bent design of the secondary filtering elbow pipe 103 enables the water flow to generate a certain centrifugal force when passing through, which helps to throw impurities such as sand and gravel towards the pipe wall, further improving the filtration effect.

[0059] Please refer to again Figure 9 , at the position where the inside of the bent part 108 is connected to the annular filter screen 106, there is a protruding annular platform 119 for supporting the annular filter screen 106.

[0060] Please refer to again Figure 10 , a fixing ring 114 is installed in the tertiary filtering pipe 113. An inner filter screen 115 is installed at the bottom of the fixing ring 114, and an outer filter screen 116 is provided outside the inner filter screen 115 and at the bottom of the fixing ring 114. A water filtering interlayer 117 is provided between the inner filter screen 115 and the outer filter screen 116.

[0061] Specifically, the water flow that directly overflows from the lower water inlet 105 into the main channel 109 bypasses the fine filtration of the secondary filtering elbow pipe 103. All the water flows that pass through the secondary filtering elbow pipe 103 or directly come from the lower water inlet 105 will flow to the tertiary filtering pipe 113 for final fine treatment after converging into the main channel 109, ensuring that the water quality output by the irrigation and fertilization integrated machine meets the requirements of landscaping. And the water filtering interlayer 117 helps to adsorb floating suspended matters in the water quality, such as small particle impurities and some dissolved organic matters, further improving the clarity of the water quality. The coordinated action of the primary filtering pipe 102, the secondary filtering elbow pipe 103 and the tertiary filtering pipe 113 not only enhances the filtration effect but also ensures the smooth flow of water, avoiding the occurrence of blockage phenomena and greatly improving the purity of the water quality.

[0062] Please refer to again Figure 10 , the bottom of the inner filter screen 115 is provided with water permeable holes 118, and the bottom of the outer filter screen 116 is closed.

[0063] More specifically, the closed design at the bottom of the outer filter screen 116 enables solid particles in the water quality, if any, to precipitate at the bottom of the outer filter screen 116 during the final filtration process, while the water flow passes through the water filtration interlayer 117 to reach the fertilizer mixing tank 3, further ensuring the degree of impurity removal of the water flow and avoiding the blockage of the drip heads in the later stage. Based on the above structure, the multi-stage filtration system can effectively remove various pollutants in the water, including organic matters, inorganic matters, particles dispersed in the water, etc., improving the safety and purity of the water quality.

[0064] Based on the above structure, the present application also provides an irrigation and fertilization method, which is detailed in the following steps:

[0065] Step 1: Check the equipment: Ensure that all components are properly connected. At the same time, check whether the drip irrigation system is in good condition, without blockage or leakage. Based on the inspection results, prepare the fertilizer solution and input the fertilization parameters.

[0066] Specifically, input the fertilization parameters, including the fertilization amount, fertilization time, fertilizer solution concentration, etc., at the control terminal 7. Add the fertilizer to the water and fertilizer tank, ensure that the fertilizer is evenly dissolved, and determine the parameters such as the fertilization amount and fertilization time according to the crop requirements.

[0067] Step 2: The control terminal 7 sends a remote instruction to the water pump, and pumps the fertilizer solution in the water and fertilizer tank into the fertilizer mixing tank 3 through the fertilizer suction pipe 6.

[0068] Step 3: Introduce the water source into the multi-stage filtration assembly 1 for multi-stage filtration, and then divert it to the inside of the fertilizer mixing tank 3.

[0069] Multi-stage filtration process:

[0070] Primary filtration: The water source enters the primary filtration pipeline 102, and the valve plate 112 is opened by the impact of the water flow. The water flow enters the secondary filtration bypass pipe 103 through the upper water inlet 104, or directly enters the main channel 109 through the lower water inlet 105. The primary filtration mainly intercepts long strip-shaped sundries such as waterweeds and withered grass.

[0071] Secondary filtration: The water flow enters the secondary filtration bypass pipe 103 and filters solid impurities such as sand and gravel through the annular filter screen 106. The inclined and bent design of the secondary filtration bypass pipe 103 generates centrifugal force, further improving the filtration effect.

[0072] Tertiary filtration: The water flow converges into the tertiary filtration pipeline 113 and undergoes final fine filtration through the inner filter screen 115 and the outer filter screen 116. The water filtration interlayer 117 adsorbs suspended matter to ensure the purity of the water quality.

[0073] Step 4: The control terminal 7 automatically adjusts the mixing ratio of the fertilizer solution and clean water according to the input fertilization parameters, then opens the ball valve 5, draws out the fertilizer solution through the industrial water pump 4 to the drip irrigation system, and the fertilizer solution is transported to the drippers or drip irrigation tapes through the distribution pipe network and slowly transported to the roots of the crops in a drip-by-drip manner;

[0074] Step 5: The control terminal 7 monitors the flow rate of the fertilizer-water in the pipeline in real time through sensors, and automatically stops fertilization when the set fertilization amount is reached.

[0075] The working principle of the present invention is as follows: The water coming out of the water pump is pumped into the multi-stage filtration assembly 1 for multi-stage filtration. The coordinated action of the primary filtration pipeline 102, the secondary filtration bypass pipe 103 and the tertiary filtration pipeline 113 in the multi-stage filtration assembly 1 not only enhances the filtration effect, but also ensures the smooth flow of water, avoids the occurrence of blockage phenomena, greatly improves the purity of the water quality. At the same time, the three-way fertilizer suction pipe 6 on the fertilizer mixing tank 3 inputs the water fertilizer into the fertilizer mixing tank 3 in proportion, mixes it with the clean water flowing in through the connecting pipeline 2, and then flows into the drip irrigation system from the water outlet of the ball valve 5 and acts on the roots of the crops;

[0076] In order to improve the irrigation water quality and ensure the working effect of the irrigation and fertilization integrated machine, this application improves the irrigation and fertilization integrated machine to improve its filtration accuracy. Specifically, a multi-stage filtration device can be added at the water inlet of the irrigation and fertilization integrated machine, and each stage of the filtration device adopts different filtration structures to gradually remove impurities such as suspended particles, organic matter and microorganisms in the water. Thus, it is ensured that the irrigation and fertilization integrated machine can always provide high-quality irrigation water sources, meet the needs of crop growth, and further improve the yield and quality of crops.

[0077] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
