Description

Technical Field

[0001] This utility model relates to the field of siphon conveying device technology, and in particular to a siphon breaking device and a siphon liquid lifting and lowering system including the same. Background Technology

[0002] A siphon works by utilizing the force of a difference in liquid level. When the higher end of the siphon is placed in a container filled with liquid, the liquid continuously flows out to a lower level through the siphon structure. Common systems using siphon structures for water supply and drainage include... Figure 1 As shown, this system includes a first container 1', a second container 2', a water pump (not shown in the figure), a water inlet pipe 3', and a siphon pipe 4'. The first container 1' is located below the second container 2'. The inlet end of the water inlet pipe 3' is connected to the water pump, which is placed inside the first container 1'. The outlet end of the water inlet pipe 3' extends into the second container 2'. The siphon pipe 4' is a U-shaped pipe, with both ends extending into the first container 1' and the second container 2' respectively. The inlet end of the siphon pipe 4' is located below the water surface in the second container 2'. When the system starts, the siphon pipe 4' is full of water (this can be achieved using a pump or valve). The pump starts, and the water supply pipe 3' begins supplying water from the first container 1' to the upper second container 2'. Simultaneously, the siphon pipe 4' opens, causing water to drain from 4' into the first container 1', creating a siphon effect. This continuously draws water from the second container 2' back into the first container 1', thus circulating the water between the two containers. When the pump stops (e.g., during a power outage), water supply to the water supply pipe 3' ceases, but the siphon pipe 4' continues to supply water due to the siphon effect. To ensure that the siphon pipe 4' stops supplying water when the water supply pipe 3' stops supplying water, a siphon break 41' needs to be installed on 4'. Air is introduced through the siphon break 41' to disrupt the siphon effect, stopping the water flow from 4'. The existing technology has the following drawbacks: 1. The existing technology generally sets the siphon 41' in the section where the siphon tube 4' extends into the second container 2', and the siphon 41' is generally close to the inlet of the siphon tube 4'. When the liquid level in the second container 2' drops to the siphon 41', the siphon 41' will be sucked in liquid mixed with air by the suction force of the siphon, generating a lot of noise and affecting the living or production environment; 2. The water level in the second container 2' is affected by the position of the siphon 41', which is not conducive to the control of the water level. Utility Model Content

[0003] The purpose of this invention is to provide a siphon breaking device and a siphon liquid up and down system including the device, which has a simple structure, low noise, and can maintain the liquid level at an optimal position after the siphon is broken.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, a siphon breaking device is provided, comprising an inlet pipe and a siphon pipe connected to a siphon liquid supply system. The siphon liquid supply system further includes a first container and a second container, wherein the height of the first container is lower than the height of the second container. The inlet pipe pumps liquid from the first container into the second container via a water pump, and the siphon pipe draws liquid from the second container into the first container via a siphon effect. The siphon breaking device comprises:

[0006] The valve body is hollow inside. A first hole and a second hole are provided on the valve body at intervals. The second hole is located at the top of the valve body. The height of the first hole is lower than the height of the second hole. The first hole is connected to the water supply pipe so that when the water supply pipe delivers liquid, some of the liquid in the water supply pipe can enter the valve body through the first hole.

[0007] A float, the float being made of a material with a density less than that of the liquid in the valve body, so that the float can float; the float can selectively block the second hole; when there is no liquid in the valve body, the float and the first hole are spaced apart or there is a gap between them to allow air to pass through.

[0008] A connecting pipe is provided, and the second hole is connected to the siphon pipe through the connecting pipe.

[0009] As a preferred embodiment of the siphon breaking device, the connecting pipe is positioned at the very top of the siphon tube.

[0010] As a preferred embodiment of the siphon breaking device, the siphon tube includes a first tube and a second tube spaced apart, the top of the first tube is connected to the top of the second tube, the bottom of the first tube is connected to the first container, the bottom of the second tube is located inside the second container, and the connecting tube is located at the top of the first tube.

[0011] As a preferred embodiment of the siphon breaking device, a siphon connecting pipe is provided between the first pipe and the second pipe, and the two ends of the siphon connecting pipe are respectively connected to the top of the first pipe and the top of the second pipe;

[0012] The siphon connecting pipe is a horizontal straight pipe; or...

[0013] The siphon connecting pipe includes an overflow structure, which includes a first overflow pipe, a second overflow pipe, and a third overflow pipe. The first overflow pipe and the second overflow pipe are horizontally spaced apart, and their lower ends are connected through the third overflow pipe. The height of the third overflow pipe is lower than the upper ends of the first pipe and the second pipe.

[0014] As a preferred embodiment of the siphon breaking device, the first hole is located at the bottom of the valve body.

[0015] As a preferred embodiment of the siphon breaking device, when the water pump stops running, the height of the liquid level in the water inlet pipe is lower than the height of the first hole.

[0016] As a preferred embodiment of the siphon breaking device, the valve body is provided with a guide structure for guiding the float to the second hole.

[0017] As a preferred embodiment of the siphon breaking device, the guiding structure includes a guide tube, the upper end of which is connected to the second hole, the float is movably disposed inside the guide tube, and multiple water passage holes are distributed outside the guide tube and / or the lower end of the guide tube is connected to the valve body.

[0018] Secondly, a siphon liquid loading and unloading system is provided, including a first container, a second container, a water pump, a water inlet pipe, and a siphon pipe, and also including the aforementioned siphon breaking device. The water inlet pipe and the siphon pipe are connected through the siphon breaking device. The height of the first container is lower than the height of the second container. The water inlet pipe pumps liquid from the first container into the second container through the water pump. The siphon pipe draws liquid from the second container into the first container through a siphon effect. After the water pump stops and starts, the outlet of the water inlet pipe is connected to the valve body through a first hole on the valve body of the siphon breaking device.

[0019] As a preferred embodiment of the siphon liquid supply and drainage system, an air inlet is provided on the water supply pipe, the air inlet is adjacent to the liquid outlet of the water supply pipe, and the height of the air inlet is higher than that of the liquid outlet of the water supply pipe.

[0020] The beneficial effects of this invention are as follows: By setting a valve body with a float ball, when the water pump starts, the water inlet pipe delivers liquid from the first container to the second container. Simultaneously, since the second hole on the valve body is always connected to the siphon pipe via a connecting pipe, and the siphon pipe is always filled with liquid and in a siphoning state, if the siphon pipe starts siphoning, the siphoning force will not only begin to draw liquid from the second container but also exert a suction force on the valve body, allowing the liquid in the water inlet pipe to enter the valve body through the first hole until the liquid level rises and the float ball is sucked to block the second hole. Furthermore, the float ball will remain blocking the second hole until the water pump stops running, thus achieving liquid circulation between the first and second containers. Furthermore, during siphon operation, because the second hole is blocked by the float, the siphon tube will not suck in liquid mixed with air, resulting in low noise. When the water pump stops starting, the liquid in the water inlet pipe and the liquid in the valve body are gradually discharged. The float, under the influence of gravity, will fall with the liquid level in the valve body or fall after the liquid level drops, leaving the second hole. When the liquid in the valve body is emptied and air is introduced through the outlet of the water inlet pipe through the first hole, the air in the valve body will enter the siphon tube through the second hole and the connecting pipe due to the gap between the float and the second hole. A large amount of air entering the siphon tube will disrupt the siphon state of the siphon tube, thereby quickly stopping the liquid circulation between the first and second containers. The entire siphon breaking device is quiet because it does not require a siphon break at the end of the siphon tube that extends into the second container. This avoids the noise generated when the liquid level in the second container drops and the siphon tube draws in liquid mixed with air through the siphon break. Furthermore, since the siphon breaking is no longer limited to the siphon break at the end of the siphon tube that extends into the second container, the liquid level in the second container is easier to maintain, making it easier to control the liquid level.

[0032] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 2 As shown (see attached) Figure 4 The siphon breaking device 1 of this utility model embodiment is used to break the siphon state of the siphon upper and lower liquid system. The siphon upper and lower liquid system includes the siphon breaking device 1, a first container 4, a second container 5, a water pump 6, a water inlet pipe 2, and a siphon pipe 3. The siphon breaking device 1 is connected to the water inlet pipe 2 and the siphon pipe 3. The height of the first container 4 is lower than the height of the second container 5. The water inlet pipe 2 pumps the liquid from the first container 4 into the second container 5 through the water pump 6. The siphon pipe 3 draws the liquid from the second container 5 into the first container 4 through the siphon effect.

[0035] The siphon breaking device 1 includes a valve body 11, a float 14, and a connecting pipe 15. The valve body 11 is hollow inside, and a first hole 12 and a second hole 13 are spaced apart on the valve body 11. The second hole 13 is located at the top of the valve body 11, and the height of the first hole 12 is lower than the height of the second hole 13. The first hole 12 is connected to the water supply pipe 2 so that when the water supply pipe 2 delivers liquid, some of the liquid in the water supply pipe 2 can enter the valve body 11 through the first hole 12. The material density of the float 14 is less than the density of the liquid in the valve body 11 so that the float 14 can float. The float 14 can selectively block the second hole 13. When there is no liquid in the valve body 11, there is a gap between the float 14 and the first hole 12, or between the two (between the float 14 and the first hole 12), allowing air to pass through, that is, the float 14 will not completely block the first hole 12. The second hole 13 is connected to the siphon pipe 3 through the connecting pipe 15.

[0036] This embodiment of the invention does not consider how the siphon tube 3 forms a siphon state, as this part belongs to the prior art. It is understood that to form a siphon state, a valve can be installed at the outlet of the siphon tube 3, allowing the siphon tube 3 to be filled with liquid when the valve is closed. Alternatively, liquid can be pumped into the siphon tube 3 using an additional pump. In summary, there are many structures for achieving a siphon state in the siphon tube 3. The core innovation of this invention does not lie in how the siphon state of the siphon tube 3 is formed, so this part will not be elaborated upon in the embodiment.

[0037] The siphon breaking device 1 of this utility model embodiment is equipped with a valve body 11 with a float ball 14. When the water pump 6 starts, the water supply pipe 2 delivers liquid from the first container 4 to the second container 5. At the same time, since the second hole 13 on the valve body 11 is always connected to the siphon pipe 3 through the connecting pipe 15, and the siphon pipe 3 is always filled with liquid and in a siphoning state, the siphon pipe 3 starts to siphon. The siphoning force of the siphon pipe 3 not only starts to draw liquid from the second container 5, but also gives a suction force to the valve body 11, so that the liquid in the water supply pipe 2 can enter the valve body 11 through the first hole 12 until the liquid level rises and the float ball 14 is sucked to block the second hole 13. The float ball 14 will block the second hole 13 until the water pump 6 stops running. At this time, the first container 4 and the second container 5 achieve liquid circulation. In the siphon operation, because the second hole 13 is blocked by the float ball 14, the siphon tube 3 will not suck in liquid mixed with air, so the noise is low. When the water pump 6 stops starting, the liquid in the water supply pipe 2 and the liquid in the valve body 11 are gradually discharged. The float ball 14 will fall with the liquid level in the valve body 11 as the liquid level drops or fall after the liquid level drops, leaving the second hole 13. When the liquid in the valve body 11 is drained and air is introduced through the outlet of the water supply pipe 2 through the first hole 12, the air in the valve body 11 will enter the siphon tube 3 through the second hole 13 and the connecting pipe 15 because the float ball 14 is separated from the second hole 13. A large amount of air entering the siphon tube 3 will disrupt the siphon state of the siphon tube 3, thereby quickly stopping the liquid circulation between the first container 4 and the second container 5. Since the entire siphon breaking device 1 does not require a siphon breaking opening on the section of the siphon tube 3 that extends into the second container 5, it avoids the noise generated when the liquid level in the second container 5 drops and the siphon tube 3 draws in liquid mixed with air through the siphon breaking opening. Therefore, the entire device has low noise. Moreover, since the siphon breaking is no longer limited to the position of the siphon breaking opening on the section of the siphon tube 3 that extends into the second container 5 (the section of the siphon tube 3 that extends into the second container 5 in this utility model no longer has a siphon breaking opening), the liquid level in the second container 5 is also easier to maintain, which facilitates liquid level control.

[0038] Optionally, the liquid flowing through components such as the first container 4, the second container 5, the water inlet pipe 2, and the siphon pipe 3 can be water or other liquids, such as coolant.

[0039] In one embodiment, such as Figure 2As shown, the first hole 12 is located at the bottom of the valve body 11. The first hole 12 being located at the bottom of the valve body 11 prevents liquid residue from remaining inside the valve body 11. Preferably, the first hole 12 is located at the lowest point of the bottom of the valve body 11. In other embodiments, the first hole 12 is not limited to being located at the bottom of the valve body 11; it can also be located on the side wall of the valve body 11. The location of the first hole 12 only needs to be lower than the position of the second hole 13, and the vertical distance between the first hole 12 and the second hole 13 needs to be greater than the size of the float 14 protruding from the liquid surface. This ensures that when air enters through the first hole 12, a gap is formed between the float 14 and the second hole 13, allowing air to pass through.

[0040] To prevent the float 14 from completely blocking the first hole 12 at the bottom of the valve body 11 after the water is drained, protrusions 16 can be provided at the bottom of the valve body 11. There are at least three protrusions 16, surrounding the outer periphery of the first hole 12. This allows the float 14 to abut against the protrusions 16 when it falls into the first hole 12, creating airflow gaps between the protrusions 16. The protrusions 16 also support the float 14, preventing it from blocking the first hole 12. Additionally, the three annularly arranged protrusions 16 provide stable support for the float 14. In other embodiments, the method is not limited to providing protrusions 16; the first hole 12 can also be located in a position where the float 14 is less likely to block it, such as at the corner between the bottom and side wall of the valve body 11.

[0041] like Figure 3 As shown, to ensure the float 14 can accurately move to the position of the second hole 13 and block it, a guide structure can be provided. This guide structure is located within the valve body 11 and guides the float 14 to the second hole 13. Further, the guide structure includes a guide tube 17, the upper end of which is connected to the second hole 13. The float 14 is movably disposed within the guide tube 17, and multiple water passage holes 171 are distributed outside the guide tube 17. By providing a guide tube 17 with water passage holes 171, liquid within the valve body 11 can enter the guide tube 17 through the water passage holes 171, allowing the float 14 to contact the liquid and move upwards as the liquid level rises. In other embodiments, it is not limited to providing water passage holes 171 on the guide tube 17; the lower end of the guide tube 17 can be directly connected to the valve body 11, i.e., the lower end of the guide tube 17 is open, facilitating liquid entry into the guide tube 17 and guiding the float 14's movement.

[0042] Preferably, the guide tube 17 is a tapered tube. The small end of the guide tube 17 surrounds the outer periphery of the second hole 13, and the large end of the guide tube 17 extends to the bottom of the valve body 11 and surrounds the outer periphery of the first hole 12. The center of the small end of the guide tube 17 is coaxially arranged with the center of the second hole 13, and the inner diameter of the small end of the guide tube 17 is slightly larger than the diameter of the float 14. The tapered guide tube 17 not only avoids the float 14 from getting stuck due to excessive space in the tube when it rises, but also ensures that the float 14 can accurately align with the second hole 13 for sealing when it rises to the position of the second hole 13.

[0043] Furthermore, an arc-shaped groove 18 is provided at the top inside the valve body 11, and the second hole 13 penetrates the bottom of the arc-shaped groove 18. The shape of the arc-shaped groove 18 matches the shape of the float 14, so that part of the float 14 can fit in the arc-shaped groove 18 to seal the second hole 13.

[0044] In one embodiment, such as Figure 2 and Figure 4 As shown, the connecting pipe 15 is connected to the siphon tube 3 at the very top of the siphon tube 3. When the siphon tube 3 is running, its top is the highest point of liquid flow. Introducing air at this position can quickly break the siphon state of the siphon tube 3.

[0045] In this embodiment, the siphon tube 3 includes a first tube 31 and a second tube 32 spaced apart. The top of the first tube 31 is connected to the top of the second tube 32, and the connecting tube 15 is located at the top of the first tube 31. The bottom of the first tube 31 is connected to the first container 4, and the bottom of the second tube 32 is located inside the second container 5. In actual use, the bottom of the second tube 32 (i.e., the liquid inlet of the siphon tube 3) is located below the liquid surface of the second container 5. By setting the connecting tube 15 corresponding to the top of the first tube 31, not only can air be smoothly introduced into the siphon tube 3 to complete the operation of breaking the siphon state, but air can also be allowed to directly enter the first tube 31 from the connecting tube 15, shortening the time for air to travel in the siphon tube 3, thereby shortening the time for the siphon tube 3 to break the siphon state.

[0046] Furthermore, a siphon connecting pipe 33 is provided between the first pipe 31 and the second pipe 32. The two ends of the siphon connecting pipe 33 are respectively connected to the top of the first pipe 31 and the top of the second pipe 32. The siphon connecting pipe 33 is a horizontal straight pipe. The siphon pipe 3 has a structure similar to an inverted U-shape, which can achieve a better siphon effect.

[0047] The water supply pipe 2 includes a third pipe 22 and a fourth pipe 23. The third pipe 22 and the fourth pipe 23 are respectively connected to the first container 4 and the second container 5. The lower end of the third pipe 22 is connected to the water pump 6, and the upper end is connected to the first hole 12 at the bottom of the valve body 11. The lower end of the fourth pipe 23 corresponds to the top opening of the second container 5. The upper end of the fourth pipe 23 is connected to the third pipe 22 through a fifth pipe 24, and the connection between the fifth pipe 24 and the third pipe 22 is located below the first hole 12.

[0048] Furthermore, an air inlet 21 is provided on the water supply pipe 2, specifically, the air inlet 21 is located on the fourth pipe 23. By providing the air inlet 21, the air can be positioned above the liquid outlet of the water supply pipe 2 (the lower end of the fourth pipe 23 is the liquid outlet of the water supply pipe 2). If the liquid level in the second container 5 is higher than the liquid outlet of the water supply pipe 2, air can still enter through this air inlet 21 after the water pump 6 stops running, thus disrupting the siphon state.

[0049] Preferably, the air inlet 21 is located in the water flow direction of the fifth pipe 24. This design allows the air inlet 21 to function as an auxiliary water outlet when the water pump 6 is running, and it also prevents water from flowing through the air inlet 21 and causing air to enter through it, thus avoiding noise. Therefore, this design can further reduce noise. More preferably, the air inlet 21 is located at the corner where the fifth pipe 24 and the fourth pipe 23 meet.

[0050] In this embodiment, when the water pump 6 stops running, the liquid level in the water inlet pipe 2 is kept lower than the height of the fifth pipe 24. This ensures that after the water pump 6 stops running, external air can be supplied to the valve body 11 through the water inlet pipe 2 and the first hole 12.

[0051] In addition, in this embodiment, the height of the liquid outlet of the water inlet pipe 2 is lower than the height of the first hole 12.

[0052] like Figure 6 As shown, this embodiment has a largely the same structure as the above embodiments, the difference being the installation height of the valve body 11. In this embodiment, the height of the fifth pipe 24 is higher than the height of the first hole 12. This design allows the water level in the valve body 11 to rise to the position where the float ball 14 can block the second hole 13 when the water pump 6 starts to fill water, even if the suction force in the siphon pipe 3 is not strong enough.

[0053] In this embodiment, the first hole 12 of the valve body 11 is connected to the non-end position of the third pipe 22 through an additional bypass pipe 25. After the water pump 6 stops running, the liquid level in the water inlet pipe 2 cannot be higher than the height of the bypass pipe 25, so as to ensure that the valve body 11 can smoothly enter the air.

[0054] The siphon destruction method in this embodiment is similar to that in the above embodiments, and will not be described again here.

[0055] like Figure 5 As shown, this embodiment and the appendix Figure 4 Similar to the previous embodiment, the difference is that an overflow structure 331 is provided on the siphon connecting pipe 33 in this embodiment. By providing the overflow structure 331, when the water pump 6 starts and the water supply pipe 2 supplies water to the second container 5, as the liquid level in the second container 5 rises, the overflow structure 331 will automatically overflow to the first pipe 31 through the principle of communicating vessels. When the overflow liquid flow rate is large enough, a siphon will be formed in the first pipe 31.

[0056] Specifically, the siphon connecting pipe 33 includes an overflow structure 331, which includes a first overflow pipe 3311, a second overflow pipe 3312, and a third overflow pipe 3313. The first overflow pipe 3311 and the second overflow pipe 3312 are horizontally spaced apart, and their lower ends are connected through the third overflow pipe 3313. That is, the overflow structure 331 is similar to an inverted U-shaped structure, and the height of the third overflow pipe 3313 is lower than the upper ends of the first pipe 31 and the second pipe 32, while the upper end of the second pipe 32 is higher than the upper end of the first pipe 31.

[0057] In this embodiment, the siphon connecting pipe 33 further includes a first connecting pipe 332 and a second connecting pipe 333. The two ends of the overflow structure 331 are respectively connected to the upper end of the second pipe 32 through the first connecting pipe 332 and to the upper end of the first pipe 31 through the second connecting pipe 333.

[0058] Specifically, in this embodiment, the upper end of the first pipe 31 is connected to the upper end of the first overflow pipe 3311 via the second conductive pipe 333, and the upper end of the second pipe 32 is connected to the upper end of the second overflow pipe 3312 via the first conductive pipe 332. The connecting pipe 15 is connected to the second conductive pipe 333 near the first pipe 31 and faces the top of the first pipe 31. The height of the second conductive pipe 333 connecting the first pipe 31 is lower than the height of the first conductive pipe 332 connecting the second pipe 32. At the same time, the height of the second conductive pipe 333 connecting the first pipe 31 is lower than the height of the second container 5.

[0059] When the overflow structure 331 is provided, in the initial state, the entire overflow structure 331 of the siphon pipe 3, the first connecting pipe 332 connecting the overflow structure 331 and the second pipe 32, and the second pipe 32 are all filled with water (filled with water using a pump or other means, only needing to be filled with water during the first start, and subsequently, according to the principle of communicating vessels, the water pump 6 will continue to be filled with water after it stops). According to the principle of communicating vessels, the liquid level in the first overflow pipe 3311 will be consistent with the liquid level in the second container 5. When the water pump 6 is running, the water supply pipe 2 delivers liquid to the second container 5, and the liquid level in the second container 5 gradually rises. The liquid level in the first overflow pipe 3311 of the siphon pipe 3 also rises to overflow into the first pipe 31 through the second guide pipe 333. When the overflow is large enough, it can drive the formation of a siphon in the first pipe 31. The siphon pipe 3 is subjected to the siphon effect, which delivers the liquid in the second container 5 to the first container 4. The siphon breaking device 1 is connected to the siphon pipe 3 through the connecting pipe 15. Therefore, the siphon suction of the siphon pipe 3 also acts on the valve body 11 of the siphon breaking device 1, causing the valve body 11 to draw liquid from the water supply pipe 2. The liquid level in the valve body 11 rises, and the float ball 14 floats upward until the float ball 14 blocks the second hole 13. At this time, the connecting pipe 15 is sealed, and the connecting pipe 15 no longer shares the suction force of the siphon pipe 3. At this time, the siphon effect of the siphon pipe 3 reaches the best state and continues to deliver liquid to the first container 4, cooperating with the water supply pipe 2 to achieve liquid circulation.

[0060] When the water pump 6 stops running, the water supply pipe 2 stops supplying water. At this time, the liquid in the valve body 11 will be discharged, and the float ball 14 will fall under the influence of gravity to expose the second hole 13. The first hole 12 of the valve body 11 will start to draw in air from the outside through the water supply pipe 2. The connecting pipe 15 will supply air to the siphon pipe 3 through the second hole 13. A large amount of air entering the siphon pipe 3 will destroy the siphon effect. According to the principle of communicating vessels, after the siphon effect of the siphon pipe 3 disappears, the liquid level in the second container 5 will continue to drop until it is level with the upper end of the first pipe 31 (i.e., the lower wall of the second connecting pipe 333 connecting the first pipe 31). Then, the overflow structure 331 of the siphon pipe 3 will no longer overflow, and the liquid level in the second container 5 will stop dropping. At this time, the siphon pipe 3 will stop supplying water, and the liquid circulation between the first container 4 and the second container 5 will be stopped.

[0061] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
