Description

Technical Field

[0001] The present invention relates to the technical field of exhaust technology for underground water supply pipeline systems, in particular to an exhaust valve and a reinforced concrete exhaust valve well. Background Art

[0002] The exhaust valve well is an underground structure in the water supply project specially used to accommodate and protect the exhaust valve. Its main function is to ensure the safe and efficient operation of the water pipeline. The exhaust valve is used to discharge the air released from the water when the pipeline is filled with water or in operation to prevent the formation of "air blockage", avoid obstructing water flow, increasing energy consumption, causing water hammer or causing flow measurement errors.

[0003] The existing exhaust valve well is generally constructed of reinforced concrete and needs to ensure a certain degree of water leakage prevention. The exhaust valve is installed in the well and connected to the underground water pipeline through a tee pipe. A float is provided inside the existing exhaust valve. When the pipeline is filled with water or running, air gathers at the top of the valve chamber, causing the water level to drop, the float drops, and drives the elastically rotating sealing rod set at one end of the exhaust pipe to deflect. The rubber seal at the end of the sealing rod is separated from the exhaust pipe port, and the exhaust pipe is opened, realizing automatic exhaust. When the water level rises, the float rises, and the sealing rod automatically rotates by elastic force to re-seal the exhaust pipe.

[0004] The shortcomings of the existing exhaust valves for exhausting underground water pipes are as follows: although the existing exhaust valves can realize the function of automatic exhaust without draining water, since there are inevitably some impurities in the passing water flow, even if it is filtered and blocked by the filter, there will be tiny impurities entering the valve body, and due to the adhesion of water, it is easy for moist debris to contact and adhere to the rubber seal at the end of the blocking rod that switches the exhaust pipe port. In the process of the blocking rod rotating to open and reset with the rubber seal, once the debris is stuck between the rubber seal at the end of the blocking rod and the end of the exhaust pipe, it will prevent the blocking rod from completing the rotation and reset action, resulting in the rubber seal being unable to completely fit into the end of the exhaust pipe for sealing. In this way, the water level will rise and leak out through the opened exhaust pipe. The existing exhaust valve has no way to effectively deal with this situation, resulting in the exhaust valve being unable to operate normally. Summary of the Invention

[0021] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0022] like Figure 1-Figure 2 As shown, the reinforced concrete exhaust valve well is used to protect the exhaust valve used in the underground pipeline of the water supply system, providing a safe, stable and dry installation environment for the exhaust valve for exhaust. The exhaust valve well includes a well body 1 made of reinforced concrete. The inner wall of the well body 1 is covered with a waterproof membrane 2. The waterproof membrane 2 is used to prevent water from seeping into the inner wall of the well body 1, which causes water accumulation in the well; a well cover is provided on the top of the well body 1, and an inspection port for people to enter and exit and a respirator for ventilation can be provided on the well cover; a bottom plate 4 is fixedly provided near the bottom of the well body 1, and an underground water pipeline 3 passes horizontally through the bottom of the well body 1 and is located below the bottom plate 4. The bottom plate 4 is used to separate the exhaust valve from the underground water pipeline 3, reducing excessive humidity in the space around the underground water pipeline 3, which directly affects the service life of the exhaust valve.

[0023] like Figure 3-Figure 17As shown, the relative position of the exhaust valve and the underground water pipeline 3 is implemented in accordance with the relevant engineering requirements in the prior art. For example, the exhaust valve is installed at the high point of the underground water pipeline 3; the exhaust valve includes a valve body 5, a floating valve mechanism, an elastic active pipe blocking mechanism and an exhaust pipe 7. The valve body 5 is connected to the underground water pipeline 3 through a tee pipe 11 and is above the bottom plate 4. The floating valve mechanism is arranged inside the valve body 5. The floating valve mechanism floats with the internal water level. The exhaust pipe 7 is horizontally arranged on one side of the top of the valve body 5 and passes through the side wall of the valve body 5. The elastic active pipe blocking mechanism is rotatably arranged on the inner top of the valve body 5, and one end of the active pipe blocking mechanism is used to block the end of the exhaust pipe 7 inside the valve body 5. The floating valve mechanism The structure includes a U-shaped frame 14 for pulling down the movable pipe blocking mechanism; when the underground water pipe 3 is conveying water, gas can enter the valve body 5 through the tee pipe 11 and gather at the inner top of the valve body 5, causing the water level in the valve body 5 to drop, and the floating valve mechanism to drop. When the water level drops below the position of the exhaust pipe 7, the U-shaped frame 14 just contacts the elastic movable pipe blocking mechanism, and then the movable pipe blocking mechanism can be pulled down by the U-shaped frame 14, causing the elastic movable pipe blocking mechanism to deflect and disengage from the exhaust pipe 7, so that the exhaust pipe 7 is opened, facilitating the discharge of gas through the exhaust pipe 7. After the gas is discharged, the water level rises, the floating valve mechanism rises, and the elastic movable pipe blocking mechanism rotates and resets to re-block the exhaust pipe 7; The above automatic exhaust process is the working principle of the exhaust valve in the prior art. The improvements are now described based on the above content. The exhaust valve also includes a clearing mechanism, which includes a transverse driving mechanism and a pushing mechanism; the transverse driving mechanism is arranged on the outside of the valve body 5, and is used to drive the exhaust pipe 7 to move laterally away from the elastic movable pipe blocking mechanism. In this way, when there is debris stuck between the exhaust pipe 7 and the elastic movable pipe blocking mechanism, the elastic movable pipe blocking mechanism will be unable to rotate and reset, affecting the sealing function. At this time, widening the distance can effectively make the debris fall down; the pushing mechanism is slidably arranged on the elastic movable pipe blocking mechanism, and the pushing mechanism is cooperatively connected with the transverse driving mechanism. The transverse driving mechanism is also used to drive the pushing mechanism to move laterally into the exhaust pipe 7 to clear the exhaust pipe 7.

[0024] It should be noted that the exhaust pipe 7 port does not use a filter to block debris, because the debris will get stuck in the mesh and is difficult to clean. As it accumulates, it is easy to get blocked and difficult to clean, so it is directly an open structure.

[0025] In some specific embodiments, such as Figure 7As shown, the elastic movable pipe blocking mechanism includes a rotating tube 15, a shaft frame 21 and a rubber sealing block 23. The shaft frame 21 is fixedly arranged on the inner top of the valve body 5 and is arranged at one end near the exhaust pipe 7 in the valve body 5; the bottom of the end of the rotating tube 15 near the exhaust pipe 7 is fixedly connected to a connecting shaft, and the connecting shaft is rotatably connected to the shaft frame 21, and a disc spring is connected between the connecting shaft and the shaft frame 21. The initial position of the rotating tube 15 is in a horizontal position, and the rubber sealing block 23 is fixedly connected to the end of the rotating tube 15 near the exhaust pipe 7, and the rubber sealing block 23 is docked with the end of the exhaust pipe 7 in the valve body 5. The diameter of the rubber sealing block 23 is larger than the caliber of the exhaust pipe 7. When the rotating tube 15 is in the initial position, the rubber sealing block 23 is squeezed and fitted on the port of the exhaust pipe 7 for sealing; the rotating tube 15 fits through the U-shaped frame 14.

[0026] In some specific embodiments, such as Figure 3 As shown, the transverse driving mechanism includes an electric telescopic rod 6, which is fixedly connected to the outside of the valve body 5 through a bracket, and the telescopic end of the electric telescopic rod 6 is parallel to the exhaust pipe 7; an elastic traction mechanism is provided inside the exhaust pipe 7, and the telescopic end of the electric telescopic rod 6 is connected to the exhaust pipe 7 through the elastic traction mechanism, and the elastic traction mechanism is also connected to the ejection mechanism.

[0027] Among them, the elastic traction mechanism includes a slender rod 8, a slip ring 28 and a first connecting spring 29. The slender rod 8 is inserted into the exhaust pipe 7, and the diameter of the slender rod 8 is much smaller than the inner diameter of the exhaust pipe 7; one end of the slender rod 8 is fixedly connected to the telescopic end of the electric telescopic rod 6 through a bracket, and the other end of the slender rod 8 is connected to a traction wire 24, and extends to the end of the exhaust pipe 7 inside the valve body 5, and is connected to the pushing mechanism through the traction wire 24. The slip ring 28 is slidingly arranged in the exhaust pipe 7, and the slender rod 8 is fixedly connected to the slip ring 28 through the bracket, and the first connecting spring 29 is connected between the slip ring 28 and the inner wall of the exhaust pipe 7, where the edge of one end of the exhaust pipe 7 outside the valve body 5 can be bent inward, and then one end of the first connecting spring 29 is fixedly connected to the bending position, and the other end is fixedly connected to the slip ring 28, and the diameter of the first connecting spring 29 is smaller than the inner diameter of the exhaust pipe 7. ; A first limit block 18 and a second limit block 19 are fixedly connected to the outer wall of the exhaust pipe 7, and the first limit block 18 is inside the valve body 5, and the second limit block 19 is outside the valve body 5. It should be noted that in order to prevent leakage at the position where the exhaust pipe 7 passes through, the first limit block 18 can be a circular ring, and a rubber telescopic sleeve 30 is connected between the first limit block 18 and the inner wall of the valve body 5. The rubber telescopic sleeve 30 wraps around the outside of the exhaust pipe 7 and covers the position where the exhaust pipe 7 passes through the valve body 5 to prevent leakage; the end of the slender rod 8 close to the electric telescopic rod 6 is fixedly connected to a strip top plate 9, and the strip top plate 9 presses on the end of the exhaust pipe 7 outside the valve body 5. Due to the presence of the second limit block 19, the second limit block 19 is in contact with the outer wall of the valve body 5, while the first limit block 18 is not in contact with the inner wall of the valve body 5, maintaining a certain distance, thereby facilitating the maintenance of the fixed position of the exhaust pipe 7 relative to the valve body 5.

[0028] When it is necessary to separate the exhaust pipe 7 from the elastic movable pipe blocking mechanism to remove the debris at the port position, the electric telescopic rod 6 is controlled to extend, and the electric telescopic rod 6 drives the slender rod 8 to move in the direction away from the valve body 5. At this time, due to the presence of the first connecting spring 29 and the first limit block 18 not fitting against the inner wall of the valve body 5, the exhaust pipe 7 can be driven to move for a period of time to separate from the rubber sealing block 23 of the elastic movable pipe blocking mechanism until the first limit block 18 contacts the inner wall of the valve body 5, and the exhaust pipe 7 stops. At this time, the gap between the end of the exhaust pipe 7 and the rubber sealing block 23 of the elastic movable pipe blocking mechanism is The distance is large enough to facilitate the falling of debris stuck between the rubber sealing block 23 and the end of the exhaust pipe 7, and to facilitate the rotation tube 15 of the elastic movable pipe blocking mechanism to rotate to a horizontal position under the action of the coil spring rebound force; then as the electric telescopic rod 6 continues to extend, the slender rod 8 can drive the slip ring 28 to move along the exhaust pipe 7 away from the elastic movable pipe blocking mechanism and compress the first connecting spring 29, so that the slender rod 8 is relatively displaced relative to the exhaust pipe 7, thereby facilitating the pulling wire 24 to pull the pushing mechanism set on the elastic movable pipe blocking mechanism horizontally into the exhaust pipe 7, thereby facilitating further unblocking of the exhaust pipe 7.

[0029] It should be noted that in this solution, a liquid sensing switch can be set at one end of the exhaust pipe 7 close to the electric telescopic rod 6 to detect whether there is a water leakage. If there is a water leakage, the operation of the electric telescopic rod 6 is controlled based on the feedback of the liquid sensing switch, or a remote alarm can be set. The liquid sensing switch is electrically connected to the remote alarm, and a remote alarm is sounded, and then the electric telescopic rod 6 is manually remotely controlled to extend and retract.

[0030] In some embodiments, combined Figures 7 to 9 As shown, the pushing mechanism includes a push rod 16 and an elastic rubber cover 22. The push rod 16 is slidably fitted and inserted into the rotating tube 15, and a compressible second connecting spring 17 is connected between the end of the push rod 16 away from the exhaust pipe 7 and the rotating tube 15; the elastic rubber cover 22 is connected to the end of the push rod 16 close to the exhaust pipe 7, and the elastic rubber cover 22 is attached to the surface of the rubber sealing block 23; the diameter of the elastic rubber cover 22 is larger than the diameter of the exhaust pipe 7, and its thickness is relatively thin, which is easy to bend. The diameter of the push rod 16 is slightly smaller than the inner diameter of the exhaust pipe 7, that is, the diameters of the two are close.

[0031] It should be noted that the middle of the rubber sealing block 23 can be a through hole to facilitate the passage of the end of the push rod 16. At the same time, the elastic rubber cover sheet 22 can be an annular sheet, which is arranged around the end of the push rod 16 to make the end surface of the end of the push rod 16 exposed, which is convenient for pushing out debris. The slender rod 8 is connected to the push rod 16 by a traction wire 24. When the rotating tube 15 is in a horizontal position, the rubber sealing block 23 and the elastic rubber cover sheet 22 at its end cooperate to squeeze and fit at the port of the exhaust pipe 7 to ensure sealing, and the traction wire 24 has a certain length and is in a relaxed state, which can avoid being affected when the rotating tube 15 is deflected, and at the same time will not pull the slender rod 8; when the rotating tube 15 is in a horizontal position, the exhaust pipe 7 moves horizontally and separates from the rotating tube 15 for a distance, the slender rod 8 is displaced relative to the exhaust pipe 7, and when the traction wire 24 is straightened, the traction wire 24 can be used to pull the push rod 16, and the push rod 16 slides relative to the rotating tube 15 toward the exhaust pipe 7. During this process, the second connecting spring 17 is compressed, and the push rod 16 penetrates into the exhaust pipe 7 horizontally. Since the diameter of the push rod 16 is slightly smaller than the inner diameter of the exhaust pipe 7, there is a certain gap between the two. During the penetration process, the end of the push rod 16 can also The elastic rubber cover sheet 22 is squeezed into the exhaust pipe 7. During the squeezing process, the edge of the exhaust pipe 7 port can scrape the end face of the elastic rubber cover sheet 22, thereby facilitating the separation of debris attached to the surface of the elastic rubber cover sheet 22. Because the elastic rubber cover sheet 22 covers the surface of the rubber sealing block 23, the debris will directly contact the elastic rubber cover sheet 22, so that separation processing is required to avoid affecting the subsequent sealing. At this time, if the exhaust pipe 7 port is flooded with water due to being open, water will continue to pass through the exhaust pipe 7, and the elastic rubber cover sheet 22 can block the exhaust pipe 7 as the push rod 16 penetrates the exhaust pipe 7, preventing water from continuing to enter the exhaust pipe 7, resulting in excessive discharge into the well body 1, and in this process, impurities in the water may have entered the exhaust pipe 7 and got stuck, and the exhaust pipe 7 can also be cleared by relying on the penetrated push rod 16.

[0032] In other specific embodiments, Figure 15 and Figure 17 As shown, one end of the slender rod 8 near the push rod 16 is fixedly connected to a connecting block 26, and the connecting block 26 is equidistantly distributed with a plurality of movable struts 25 near the center position, and each movable strut 25 is movably connected to the connecting block 26 by a rebound hinge, and the end of each movable strut 25 is a tilted arc end. In the initial state, the distributed movable struts 25 are in a retracted state. When the slender rod 8 is reset, in order to prevent the end of the push rod 16 from being stuck in the exhaust pipe 7 due to the presence of the elastic rubber cover 22 and unable to rely on the rebound force of the second connecting spring 17 to reset, the movable struts 25 distributed at the end of the slender rod 8 will come into contact with the end of the push rod 16, and due to the squeezing effect and the presence of the tilted arc end at the end, it deflects and opens, thereby facilitating the increase of the contact range between the end of the slender rod 8 and the push rod 16, making it easier for the slender rod 8 to push the push rod 16 and push the push rod 16 out of the exhaust pipe 7, so that it is completely and effectively reset.

[0033] In some specific embodiments, in order to facilitate the collection of debris during the unblocking process of the exhaust pipe 7, the exhaust valve also includes an expansion box 20, which is fixedly connected to the exhaust pipe 7 and divides the exhaust pipe 7 into two sections, and is connected to both sections of the exhaust pipe 7. The width and depth of the expansion box 20 are both greater than the diameter of the exhaust pipe 7. When the push rod 16 penetrates into the exhaust pipe 7, if there is debris, the debris can be pushed into the expansion box 20 to ensure that the exhaust pipe 7 is effectively unblocked.

[0034] It should also be noted that a detachable valve cover is provided on the top of the valve body 5 and a detachable end plate is provided on the back of the expansion box 20, so as to facilitate disassembly and removal of debris during subsequent maintenance.

[0035] In some embodiments, combined Figure 9 and Figure 10 As shown, a liquid level sensor 27 is installed on one side of the interior of the expansion box 20. The liquid level sensor 27 is electrically connected to the electric telescopic rod 6. When the port of the exhaust pipe 7 cannot be properly sealed, resulting in water inflow, the water will accumulate in the expansion box 20. When the accumulated amount reaches a certain amount, the liquid level sensor 27 detects that the liquid level exceeds the set value and feeds back to the matching controller. The controller makes a judgment based on the received signal and controls the extension of the electric telescopic rod 6.

[0036] In this embodiment, in order to prevent the exhaust pipe 7 from being completely blocked, which would prevent a certain amount of water from gathering in the expansion box 20 and automatically triggering the electric telescopic rod 6, a waterproof pressure sensor electrically connected to the electric telescopic rod 6 can be provided on the inner wall of one end of the exhaust pipe 7 located within the valve body 5. When the exhaust pipe 7 is blocked and the end of the exhaust pipe 7 is opened, the pressure generated by the air gathered in the valve body 5 will act on the waterproof pressure sensor, which can also cause the electric telescopic rod 6 to extend. At this time, a remote alarm can be provided that is electrically connected to the waterproof pressure sensor, and the electric telescopic rod 6 can also be provided with a remote wireless controller to easily remind relevant operators to reset the electric telescopic rod 6.

[0037] In other specific embodiments, an induction switch 31 is fixedly installed on the inner wall of one end of the exhaust pipe 7 close to the electric telescopic rod 6. Here, the induction switch 31 can be a pressure induction switch or other contact-triggered feedback switch. The induction switch 31 is aligned with the edge of the slip ring 28, and a micro water pump 32 electrically connected to the induction switch 31 is installed on one side of the bottom of the expansion box 20. The negative pressure end of the micro water pump 32 is connected to the inside of the expansion box 20, and the water outlet end is connected to the outside of the well body 1 through a pipe. The power supply of the micro water pump 32 and the electric telescopic rod 6 can be connected to the mains, and the circuit can be distributed through the manhole cover on the well body 1.

[0038] When the slender rod 8 slides with the slip ring 28 relative to the exhaust pipe 7 and pulls the push rod 16 into the exhaust pipe 7 through the traction wire 24, as the slip ring 28 continues to slide, when the push rod 16 passes through the position of the expansion box 20, the slip ring 28 contacts the sensor switch 31, and the sensor switch 31 enables the micro water pump 32 to operate, and the micro water pump 32 pumps out the accumulated water in the expansion box 20. When the water level is lower than the set value, the liquid level sensor 27 feeds back a signal to the matching controller, and the controller performs logical judgment based on the received signal, and controls the electric telescopic rod 6 to retract and perform a reset action.

[0039] In some specific embodiments, the set value below which the water level is lower than the set value above which the water level is higher can be set to different values ​​to ensure that the micro pump 32 can fully pump out the water in the expansion box 20 .

[0040] In some specific embodiments, such as Figure 5 As shown, the floating valve mechanism includes a float 13, which is arranged inside the valve body 5, a U-shaped frame 14 is fixedly connected to the top of the float 13, a guide rod 12 is fixedly connected to the bottom of the float 13, a guide sleeve 10 is fixedly provided below the valve body 5, and the guide rod 12 slides through the guide sleeve 10, the float 13 is made of buoyant material, can rise and fall with the water level, and the guide rod 12 and the guide sleeve 10 cooperate to make the float 13 float up and down stably.

[0041] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios: During the water delivery operation of the underground water pipeline 3, gas will gather at the top of the valve body 5 through the pipeline, causing the internal water level to drop, and the float 13 will drop along with the water level. When the water level drops below the position of the exhaust pipe 7, the U-shaped frame 14 just contacts the rotating pipe 15 of the elastic movable pipe blocking mechanism. Then the float 13 pulls down the rotating pipe 15 through the U-shaped frame 14, causing the rotating pipe 15 to deflect relative to the shaft frame 21. The rubber sealing block 23 at the end of the rotating pipe 15 will deflect synchronously and disengage from the port of the exhaust pipe 7 in the valve body 5, thereby facilitating the rapid discharge of air into the well body 1 through the opened exhaust pipe 7, thereby ensuring the normal operation of the underground water pipeline 3. When the exhaust is completed, the water level rises and the float 13 rises. At this time, the rotating tube 15 can rotate by relying on the rebound force of the coil spring, and rely on the rubber sealing block 23 to squeeze and fit to the port of the exhaust pipe 7 for sealing. It should be noted that the rubber sealing block 23 can be squeezed and deformed to facilitate sealing during the rotation process.

[0042] If impurities are stuck between the rubber sealing block 23 and the exhaust pipe 7 during the rotation and reset process of the rotating tube 15 with the rubber sealing block 23, the rotation of the rotating tube 15 is blocked and the exhaust pipe 7 end cannot be closed. At this time, water will flow into the exhaust pipe 7 and the water will be collected in the expansion box 20. When the collection reaches a certain amount, the liquid level sensor 27 detects that the liquid level exceeds the set value and feeds back to the matching controller. The controller makes a judgment based on the received signal and controls the electric telescopic rod 6 to extend. The electric telescopic rod 6 drives the slender rod 8 to move away from the valve body 5. At this time, due to the presence of the first connecting spring 29 and the first limit block 18 not being in contact with the inner wall of the valve body 5, the exhaust pipe 7 can be driven to move a certain distance. The exhaust pipe 7 is separated from the rubber sealing block 23 at the end of the rotating tube 15 by a certain distance, which facilitates the falling of the debris stuck between the rubber sealing block 23 and the end of the exhaust pipe 7, and facilitates the rotating tube 15 of the elastic movable pipe blocking mechanism to rotate to a horizontal position under the action of the coil spring rebound force, so that the push rod 16 is aligned with the exhaust pipe 7 end.

[0043] Then, as the electric telescopic rod 6 continues to extend, the slender rod 8 can drive the slip ring 28 to move along the exhaust pipe 7 in the direction away from the rotating tube 15 and compress the first connecting spring 29. In this way, the slender rod 8 is relatively displaced relative to the exhaust pipe 7, thereby facilitating the pulling of the push rod 16 by the traction wire 24, and the push rod 16 slides toward the exhaust pipe 7 relative to the rotating tube 15. During this process, the second connecting spring 17 is compressed, and the push rod 16 is laterally penetrated into the exhaust pipe 7. Since the diameter of the push rod 16 is slightly smaller than the inner diameter of the exhaust pipe 7, there is a certain gap between the two. During the penetration process, the end of the push rod 16 can also squeeze into the exhaust pipe 7 with the elastic rubber cover 22. During the extrusion process, the edge of the exhaust pipe 7 port can press the end surface of the elastic rubber cover 22. The elastic rubber cover 22 is scraped to separate the debris attached to the surface of the elastic rubber cover 22. Because the elastic rubber cover 22 covers the surface of the rubber sealing block 23, the debris will directly contact the elastic rubber cover 22, so it needs to be cleaned to avoid affecting the subsequent sealing. At this time, if the exhaust pipe 7 port is flooded with water in the open state, the impurities in the water may have entered the exhaust pipe 7 and got stuck. The inserted push rod 16 can also push the impurities to make the entered impurities fall into the expansion box 20, dredge the interior of the exhaust pipe 7, and avoid affecting the subsequent exhaust. The elastic rubber cover 22 also blocks the exhaust pipe 7 as the push rod 16 penetrates the exhaust pipe 7, preventing water from continuously entering the exhaust pipe 7 for a long time and generating excessive water to be discharged into the well body 1.

[0044] When the push rod 16 passes through the position of the expansion box 20, the slip ring 28 contacts the induction switch 31, and the induction switch 31 causes the micro water pump 32 to operate. The micro water pump 32 then pumps out the accumulated water in the expansion box 20. When the water level is lower than the set value, the liquid level sensor 27 feeds back a signal to the matching controller. The controller performs logical judgment based on the received signal and controls the electric telescopic rod 6 to retract and reset. The retracted and reset electric telescopic rod 6 pushes the exhaust pipe 7 to the top through the strip top plate 9 to reset it for continued use.

[0045] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
