Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, and in particular to a feed mixing device for automatic drug administration in laying hen farming. Background Technology

[0002] In large-scale egg-laying hen farming, disease prevention and control and daily health care are the core links to ensure the survival rate, egg production rate and egg quality of laying hens. Drinking water administration has become the most common method of drug administration in egg-laying hen farming due to its advantages such as convenient operation, uniform drug administration and low stress. However, due to insufficient manual mixing, some poorly soluble drugs are prone to precipitation and stratification in the water, resulting in uneven drug intake by laying hens in different farming areas, which affects the overall prevention and control effect. As egg-laying hen farming is upgraded towards intensification and automation, drug mixing devices have become the key to promoting the standardization and intelligent development of disease prevention and control in egg-laying hen farming, reducing farming costs, and ensuring the health of laying hens and the safety of products. Current technology typically involves directly adding the medication to the drinking system or storage container and stirring to promote dissolution. However, chickens cannot drink the water containing the medication in a short time. After a long period of sedimentation, the medication and water separate into layers, and the chickens can only drink the upper layer, resulting in insufficient medication. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing an automatic medication mixing device for laying hen farming. This invention, through its feeding mechanism, causes the liquid level of the medication in the water tank to rise as it flows in through the outlet pipe. A magnet then drives a second stopper to close the outlet pipe, preventing the medication from overflowing. As the amount of medication in the tank decreases due to drinking, the outlet pipe reopens, achieving automatic water replenishment. This process repeats, adding the mixed medication from the tank to the water tank in batches. This achieves the effect of distributing a small portion of the medication from the tank into the water tank while the majority remains in the tank for continuous stirring. This avoids the situation in existing technologies where medication is directly added to the water tank, causing the chickens to not finish drinking the medication-containing water in a short time, resulting in medication re-precipitation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic drug-dispensing mixing device for laying hen farming, comprising a water tank, an inlet at the top of the water tank, a stirring motor mounted on the bottom outer wall of the water tank, a stirring paddle mounted on the main shaft of the stirring motor inside the water tank, a feeding mechanism and an auxiliary mechanism disposed within the water tank, the feeding mechanism comprising a water outlet pipe disposed at the bottom of the water tank, a sliding rod slidably inserted into the water outlet pipe, and a through hole axially formed on the outer wall of the sliding rod. A first stopper is fixed to the top outer wall of the slide rod, and a second stopper is fixed to the outer wall of the end of the slide rod away from the first stopper. A magnet that can be attracted to the end wall of the water outlet pipe is provided on the outer wall of the second stopper. A water trough is rotatably connected to the bottom outer wall of the water tank. The outlet of the water pipe faces the opening of the water trough. A float that slides into the water trough is installed on the bottom outer wall of the slide rod. A lever that abuts against the float is provided on the inner wall of the water trough. A rotating motor for driving the water trough is provided on the outer wall of the water tank.

[0005] Preferably, the auxiliary mechanism includes a grinding rod mounted on the main shaft of the stirring motor, a filter screen cover coaxially distributed with the feed inlet on the top inner wall of the water tank, the filter screen cover being slidably sleeved on the outer wall of the grinding rod, and a tamping rod being slidably inserted into the feed inlet.

[0006] Preferably, the tamping rod has a transmission chamber axially inside, and an extension rod extending through the tamping rod along the axis is provided on the outer wall of the end of the grinding rod away from the stirring motor. A second wedge is fixed on the top inner wall of the transmission chamber.

[0007] Preferably, a first wedge is fixed on a section of the outer wall of the transmission chamber of the extension rod, the first wedge abuts against a second wedge, and a spring is provided between the outer wall of the first wedge and the inner wall of the transmission chamber.

[0008] Preferably, the top outer wall of the tamping rod is provided with a limiting rod that is slidably inserted into the top outer wall of the water tank. The limiting rod passes through the water tank and extends into the receiving trough. The outer wall of the limiting rod is provided with two sets of paddles located in the water tank and the water trough, respectively. The paddle located in the water tank is positioned above the contact point between the grinding rod and the tamping rod.

[0009] Preferably, a storage groove is provided on the bottom outer wall of the water tank, the water tank is rotatably connected to the storage groove via a rotating shaft, the rotating shaft of the water tank is fixed on the main shaft of the flip motor, and a partition extending into the water tank is provided on the top inner wall of the storage groove.

[0010] Preferably, a collection trough is provided on the bottom outer wall of the water tank on the side away from the collection trough, and an abutment plate that can extend to the inlet of the collection trough is provided on the outer wall of the water tank on the side near the collection trough.

[0011] Preferably, the water tank has a mounting bracket on the outer wall near the collection trough for mounting on the wall, and the opening of the collection trough faces away from the wall.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through its feeding mechanism, causes the liquid level of the medicine flowing into the water tank through the outlet pipe to rise. A magnet then drives a second stopper to close the outlet pipe, preventing the medicine from overflowing. As the amount of medicine in the water tank decreases due to drinking, the outlet pipe reopens, achieving automatic water replenishment. This process repeats, adding the mixed medicine from the tank to the water tank in batches. This achieves the effect of distributing a small portion of the medicine from the tank into the water tank while keeping the majority in the tank for continuous stirring. This avoids the situation in existing technologies where medicine is directly added to the water tank, causing the chickens to be unable to drink the medicine-containing water quickly enough, resulting in the medicine re-precipitating.

[0013] 2. This invention, through its auxiliary mechanism, allows for the following process: When medication is administered via drinking water, the tamping rod is pulled out of the inlet, and the medication granules are fed into the water tank. Under the action of the filter screen, the granules are intercepted at the top of the tamping rod. Based on the medication-to-water ratio, an appropriate amount of water is injected into the water tank through the inlet, and then the tamping rod is inserted back into the inlet. At this point, the inlet is closed to prevent external contaminants from entering the water tank. Under the action of the spring, the tamping rod continuously compresses the medication granules. The stirring motor is then activated, causing the grinding rod to rotate, gradually grinding the medication granules into easily soluble small particles. Simultaneously, the stirring motor drives the stirring paddle to rotate, allowing the medication granules to dissolve quickly and mix evenly with the water.

[0014] 3. The present invention, through the setting of a first wedge and a second wedge, enables the tamping rod to move up and down reciprocally under the cooperation of the second wedge and the first wedge and the reset action of the spring, thereby crushing the residual drug particles in the filter screen and further improving the drug particle dissolution effect. At the same time, the tamping rod drives the paddle to move up and down synchronously through the limiting rod. The paddle located in the water tank can assist in stirring and prevent the drug solution in the water tank from separating. During the up and down reciprocating movement of the paddle located in the water trough, it can prevent the drug solution in the water trough from forming sediment, further avoiding the situation of insufficient drug administration caused by drug sedimentation after a long period of stillness in the prior art.

[0015] 4. This invention, through the design of a partition, allows the water tank's opening to rotate towards the collection tank via a flipping motor after operation, until the abutment plate contacts the top outer wall of the collection tank. This allows any remaining medicine in the water tank to be poured into the collection tank for collection, preventing environmental pollution or spoilage that could lead to accidental ingestion by the chickens. Furthermore, during the water tank's rotation, a lever moves a float downwards, causing the float to move a sliding rod downwards. This causes the sliding rod to slide the first stopper into the outlet pipe, closing the outlet pipe. Simultaneously, the water tank's opening is blocked by the partition after rotation, preventing external contaminants from entering when the device is idle. Compared to existing open water tank designs that require cleaning before each use, this invention allows the water tank to be stored away when not in use, ensuring its cleanliness and reducing the frequency of cleaning.

[0018] 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. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] See Figures 1 to 9 As shown, an automatic drug dosing mixing device for egg-laying chicken farming includes a water tank 1, a feed inlet 11 on the top of the water tank 1, a stirring motor 2 installed on the bottom outer wall of the water tank 1, a stirring paddle 21 located inside the water tank 1 installed on the main shaft of the stirring motor 2, and a feeding mechanism and an auxiliary mechanism are provided inside the water tank 1. The feeding mechanism includes a water outlet pipe 15 located at the bottom of the water tank 1. A sliding rod 41 is slidably inserted into the water outlet pipe 15. A through hole 411 is axially formed on the outer wall of the sliding rod 41. A first stopper 42 is fixed on the top outer wall of the sliding rod 41. A second stopper 43 is fixed on the outer wall of the end of the sliding rod 41 away from the first stopper 42. A magnet 431 capable of adsorbing onto the end wall of the water outlet pipe 15 is provided on the outer wall of the second stopper 43. A water trough 3 is rotatably connected to the bottom outer wall of the water tank 1. The opening of the water outlet pipe 15 faces the opening of the water trough 3. A float 4 is slidably inserted into the water trough 3 on the bottom outer wall of the sliding rod 41. A lever 33 abutting against the float 4 is provided on the inner wall of the water trough 3. A rotating motor 31 for driving the water tank 3 is provided on the outer wall of the water tank 1. A storage groove 13 is provided on the bottom outer wall of the water tank 1. The water tank 3 is rotatably connected to the storage groove 13 through a rotating shaft. The rotating shaft of the water tank 3 is fixed on the main shaft of the rotating motor 31. A partition 131 extending into the water tank 3 is provided on the top inner wall of the storage groove 13. A collection groove 14 is provided on the bottom outer wall of the water tank 1 away from the storage groove 13. An abutment plate 32 that can extend to the inlet of the collection groove 14 is provided on the outer wall of the water tank 3 near the collection groove 14. A fixing bracket 12 for mounting on the wall is provided on the outer wall of the water tank 1 near the collection groove 14. The opening of the storage groove 13 faces the side away from the wall.

[0020] It should be noted that in the initial state, the opening of the water tank 3 is flipped to face the collection tank 14. At this time, the abutment plate 32 abuts against the top outer wall of the collection tank 14, so that the remaining medicine in the water tank 3 can be poured into the collection tank 14 for collection, avoiding the medicine from polluting the environment or deteriorating and causing the chickens to accidentally ingest it. In addition, during the flipping process of the water tank 3, the lever 33 moves the float 4 downward, which causes the float 4 to drive the slide rod 41 downward, so that the slide rod 41 drives the first plug 42 to slide into the water outlet pipe 15. At this time, the water outlet pipe 15 is closed, and the outer walls of the tamping rod 5 and the grinding rod 22 are tightly fitted with the inner wall of the filter screen 16.

[0021] When water and medicine are needed, pull out the mixing rod 5 from the feed inlet 11 and put the medicine granules into the water tank 1 from the feed inlet 11. Start the stirring motor 2 to drive the stirring paddle 21 to rotate, so that the medicine granules and water are fully mixed. After the mixture is completed, drive the water tank 3 to flip it to the position with the opening facing upward by the flipping motor 31. The water tank 3 drives the abutment plate 32 to flip synchronously, so that the abutment plate 32 pushes the float 4 to move upward. The float 4 drives the slide rod 41 to move upward synchronously, so that the slide rod 41 pushes the first stopper 42 to slide out of the water outlet pipe 15 and into the water tank 1. At this time, the through hole 411 on the slide rod 41 connects the water tank 1 and the water outlet pipe 15, so that the medicine water that has been mixed in the water tank 1 flows into the water tank 3 through the water outlet pipe 15. When the chickens drink water through the water tank 3, the water and medicine feeding process is completed.

[0022] Simultaneously, as the liquid level of the medicine flowing into the water tank 3 through the outlet pipe 15 rises, the float 4 gradually floats upward due to buoyancy. This causes the float 4 to push the slide rod 41 further upward, which in turn pushes the second stopper 43 and the magnet 431 upward. As the magnet 431 approaches the outlet pipe 15, the magnetic force between the magnet 431 and the outlet pipe 15 gradually increases. When the magnetic force between the magnet 431 and the outlet pipe 15 and the buoyancy of the float 4 can overcome the weight of the components on the slide rod 41, the magnet 431 can adhere to the end wall of the outlet pipe 15. This causes the magnet 431 to drive the second stopper 43 to close the outlet pipe 15, preventing the medicine in the water tank 3 from overflowing. As the medicine in the water tank 3 is consumed, the liquid level decreases. When the liquid level of the medicine in the water tank 3 decreases, the float 4 loses its buoyancy support. At this time, the magnetic force of the magnet 431 alone is insufficient to overcome the weight of the components on the slide rod 41, causing the slide rod 41 to move down. The second stopper 43 and the magnet 431 separate from the water outlet pipe 15, thereby opening the water outlet pipe 15 and achieving the effect of automatic water replenishment. This process is repeated to add the mixed medicine in the water tank 1 to the water tank 3 in batches. This achieves the effect of putting a small portion of the medicine in the water tank 1 into the water tank 3, while keeping most of it in the water tank 1 for continuous stirring. This avoids the situation in the existing technology where the medicine is directly put into the water tank 3, causing the chickens to not be able to drink the water containing the medicine in a short time, resulting in the medicine re-precipitating.

[0023] Considering that the water level in the water tank 3 will fluctuate when the chickens drink, the baffle 131 can block some of the fluctuations from being transmitted to the area where the float 4 is located, thereby reducing the impact of the water level fluctuations on the float 4. At the same time, it can prevent the chickens from accidentally touching the float 4. Furthermore, this device does not require precise control of the displacement of the float 4. Even if the water level fluctuations cause the float 4 to move up and down, the magnet 431 can still be attracted to the water outlet pipe 15 when the water level rises to a certain position. At the same time, if the water level is low, the float 4 will move up and down, causing the magnet 431 to be attracted to the water outlet pipe 15. When the fluctuating water level falls back, the float 4 loses buoyancy, and the magnet 431 will still separate from the water outlet pipe 15. In addition, to prevent the medicine in the water tank 3 from overflowing due to the water level fluctuations, the highest position of the float 4 is designed to be the water level when the water volume in the water tank 3 reaches 80% of its volume. When the water volume in the water tank 3 reaches 80% of its volume, the float 4 drives the second stopper 43 to close the water outlet pipe 15.

[0024] In addition, when medication is not required, this device can be used as a water supply device to provide drinking water to the chicken house. Furthermore, this device is applicable to the addition of both liquid and solid medications, which greatly improves the practicality of the device. Considering that the filter screen 16 may become clogged during the grinding process of the medication particles, the clogged particles will gradually be dissolved as the stirring paddle 21 stirs.

[0025] After the work is completed, the tilting motor 31 drives the opening of the water tank 3 to turn towards the collection tank 14 until the abutment plate 32 abuts against the top outer wall of the collection tank 14. This allows the remaining medicine in the water tank 3 to be poured into the collection tank 14 for collection, preventing the medicine from polluting the environment or deteriorating and causing the chickens to accidentally ingest it. During the tilting process of the water tank 3, the lever 33 moves the float 4 downward, causing the float 4 to move the slide rod 41 downward. This causes the slide rod 41 to move the first stopper 42 into the outlet pipe 15, at which point the outlet pipe 15 is closed. At the same time, the opening of the tilted water tank 3 is blocked by the partition 131, preventing external pollutants from entering when the device is not in use. Compared with the open design of the existing water tank 3, which requires cleaning before each use, this invention can store the water tank 3 when not in use, ensuring the cleanliness of the water tank 3 and reducing the number of times the device needs to be cleaned.

[0026] The auxiliary mechanism includes a grinding rod 22 mounted on the main shaft of the stirring motor 2. A filter screen 16, coaxially distributed with the feed inlet 11, is installed on the top inner wall of the water tank 1. The filter screen 16 is slidably sleeved on the outer wall of the grinding rod 22. A tamping rod 5 is slidably inserted into the feed inlet 11. A transmission chamber 51 is axially formed inside the tamping rod 5. An extension rod 23, extending axially through the tamping rod 5, is provided on the outer wall of the end of the grinding rod 22 away from the stirring motor 2. A second wedge 511 is fixed on the top inner wall of the transmission chamber 51. A section of the extension rod 23 is located inside the transmission chamber 51. A first wedge 232 is fixed on the outer wall, and the first wedge 232 abuts against the second wedge 511. A spring 234 is provided between the outer wall of the first wedge 232 and the inner wall of the transmission chamber 51. A limiting rod 52 is provided on the outer wall of the top of the tamping rod 5, which is slidably inserted into the outer wall of the top of the water tank 1. The limiting rod 52 passes through the water tank 1 and extends into the storage groove 13. Two sets of paddles 521 are provided on the outer wall of the limiting rod 52, which are located in the water tank 1 and the water trough 3 respectively. The paddle 521 located in the water tank 1 is positioned above the abutment of the grinding rod 22 and the tamping rod 5.

[0027] It should be noted that when medication is administered via drinking water, the tamping rod 5 is pulled out of the feed inlet 11, and the medicine granules are put into the water tank 1 through the feed inlet 11. Under the action of the filter screen 16, the medicine granules are intercepted at the top of the grinding rod 22. According to the medicine-to-water ratio, an appropriate amount of water is injected into the water tank 1 through the feed inlet 11, and then the tamping rod 5 is inserted into the feed inlet 11. At this time, the feed inlet 11 is closed to prevent external contaminants from entering the water tank 1. Under the action of the spring 234, the tamping rod 5 continuously squeezes the medicine granules. The stirring motor 2 is started, and the stirring motor 2 drives the grinding rod 22 to rotate, so that the medicine granules are gradually ground into easily soluble small particles. At the same time, the stirring motor 2 drives the stirring paddle 21 to rotate, so that the medicine granules dissolve quickly and mix evenly with the water.

[0028] Furthermore, as the drug particles are gradually ground and their volume decreases, the tamping rod 5 gradually moves downward. The tamping rod 5 drives the second wedge block 511 to move downward synchronously. The stirring motor 2 drives the first wedge block 232 to rotate synchronously via the extension rod 23. When the second wedge block 511 abuts against the first wedge block 232, under the cooperation of the second wedge block 511 and the first wedge block 232 and the reset action of the spring 234, the tamping rod 5 moves up and down reciprocally, thereby crushing the residual drug particles in the filter screen 16 and further improving the drug particle dissolution effect. At the same time, the tamping rod 5 drives the paddle 521 to move up and down synchronously via the limiting rod 52. The device features a stirring mechanism. The stirring plate 521 located in water tank 1 helps to stir the liquid and prevent the liquid from separating. The stirring plate 521 located in water trough 3 gently stirs the liquid as it moves up and down, preventing the liquid from settling. This further avoids the problem of insufficient medication caused by long-term static liquid sedimentation, which is common in existing technologies. Moreover, because chickens are visually sensitive, the liquid surface fluctuations caused by the reciprocating movement of the stirring plate 521 will arouse their curiosity and encourage them to approach and explore. This is especially suitable for flocks that have just changed their drinking location or type of water, and can increase their willingness to drink to a certain extent.

[0029] Working principle: The device is installed on the wall of the chicken house by the fixing frame 12. The height of the water trough 3 from the ground should be close to the height of the chicken's back from the ground, so that when the chicken stands naturally, its head can easily reach into the water trough 3 to drink water, avoiding the situation where the water trough 3 is too high and the chicken cannot drink water. At the same time, by setting the water trough 3 at a certain height, the possibility of excrement and other impurities in the chicken house entering the water trough 3 can be reduced. When medication needs to be administered via drinking water, the bottom end of the tamping rod 5 is fully pulled out of the feed inlet 11. The distance between the paddle 521 inside the water tank 1 and the top of the water tank 1, and the distance between the paddle 521 inside the water trough 3 and the top of the receiving trough 13, are both greater than the distance between the bottom end of the tamping rod 5 and the top of the water tank 1. This ensures that the paddle 521 will not obstruct the complete extension of the tamping rod 5 out of the feed inlet 11. The medication granules are then fed into the water tank 1 through the feed inlet 11. Under the action of the filter screen 16, the medication granules are intercepted at the top of the tamping rod 22. Figure 8 As shown, according to the drug-water ratio, after injecting an appropriate amount of water into the water tank 1 through the feed inlet 11, the tamping rod 5 is reinserted into the feed inlet 11. At this time, the feed inlet 11 is closed. The stirring motor 2 is started to drive the stirring paddle 21 to rotate. Under the action of the auxiliary mechanism, the stirring motor 2 drives the grinding rod 22 to rotate, so that the drug particles are gradually ground into easily soluble small particles. At the same time, the stirring motor 2 drives the stirring paddle 21 to rotate, so that the drug particles dissolve quickly and mix evenly with the water, so that the drug particles and water are fully mixed. After the mixing is completed, the water tank 3 is driven to rotate to the state with the tank opening facing upward by the flipping motor 31. Under the action of the feeding mechanism, the water trough 3 drives the abutment plate 32 to rotate synchronously, causing the abutment plate 32 to push the float 4 upward. The float 4 drives the slide rod 41 to move upward synchronously, so that the slide rod 41 pushes the first stopper 42 to slide out of the water outlet pipe 15 and into the water tank 1. At this time, the water outlet pipe 15 is opened, and the through hole 411 on the slide rod 41 connects the water tank 1 and the water outlet pipe 15, so that the medicine solution mixed in the water tank 1 flows into the water trough 3 through the water outlet pipe 15. At this time, the chickens can drink water through the water trough 3. At the same time, as the liquid level of the medicine solution flowing into the water trough 3 through the water outlet pipe 15 rises, the float 4 is gradually floated by buoyancy, so that the float 4 pushes the slide rod 41 to move further upward, so that the slide rod 41 pushes the second stopper 43 and the magnet 431 to move upward gradually. As the magnet 431 approaches the water outlet pipe 15, the magnetic force between the magnet 431 and the water outlet pipe 15 gradually increases. When the magnetic force and the buoyancy of the float 4 can overcome the weight of the components on the slide bar 41, the magnet 431 can be attracted to the end wall of the water outlet pipe 15, thereby causing the magnet 431 to drive the second stopper 43 to close the water outlet pipe 15, preventing the medicine in the water tank 3 from overflowing. Similarly, as the amount of medicine in the water tank 3 decreases due to drinking, the liquid level of the medicine in the water tank 3 drops, causing the float 4 to lose its buoyancy support. At this time, the magnetic force of the magnet 431 alone is not enough to overcome the weight of the components on the slide bar 41, causing the water outlet pipe 15 to be opened again, achieving the effect of automatic water replenishment. This process is repeated, and the mixed medicine in the water tank 1 is added to the water tank 3 in batches, achieving the effect of putting a small portion of the medicine in the water tank 1 into the water tank 3, while most of it remains in the water tank 1 for continuous stirring. This avoids the situation in the existing technology where the medicine is directly added to the water tank 3, causing the chickens to not be able to drink the water containing the medicine in a short time, resulting in the medicine settling again. Under the action of the auxiliary mechanism, when there are medicinal particles between the end of the tamping rod 5 and the end of the grinding rod 22, the end of the tamping rod 5 cannot contact the end of the grinding rod 22. At this time, the second wedge 511 on the tamping rod 5 moves upward and separates from the first wedge 232. As the medicinal particles are gradually ground and their volume decreases, the tamping rod 5 gradually moves downward. The tamping rod 5 drives the second wedge 511 to move downward synchronously. The stirring motor 2 drives the first wedge 232 to rotate synchronously through the extension rod 23. When the second wedge 511 abuts against the first wedge 232, under the cooperation of the second wedge 511 and the first wedge 232 and the reset action of the spring 234, the tamping rod 5 moves up and down reciprocally, thereby crushing the remaining medicinal particles in the filter screen 16. The process further improves the dissolution effect of the drug granules. At the same time, the stirring rod 5 drives the paddle 521 to move up and down synchronously through the limiting rod 52. The paddle 521 located in the water tank 1 can assist in stirring and prevent the drug solution in the water tank 1 from separating. During the up and down movement of the paddle 521 located in the water trough 3, it can prevent the drug solution in the water trough 3 from forming sediment. This further avoids the situation of drug sedimentation after a long period of stillness in the existing technology, which leads to insufficient drug administration. Moreover, since chickens are visually sensitive, the liquid surface fluctuations generated by the reciprocating movement of the paddle 521 will arouse the curiosity of the chickens and make them actively approach to explore. This is especially suitable for flocks that have just changed their drinking position and drinking type, and can improve the chickens' willingness to drink to a certain extent.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
