Description

Technical Field

[0001] This invention belongs to the field of diaphragm booster pump technology, specifically relating to a pressure plate, pump cavity structure, diaphragm booster pump, and exhaust method. Background Technology

[0002] A diaphragm booster pump is a liquid conveying mechanism. Traditional self-priming pumps cannot instantly draw in water and pressurize in a very small water tank, and instantly expel water. The current drawback of such products on the market is that it takes tens of seconds to expel the air that has entered the tank. Therefore, the long waiting time is the biggest problem of desktop RO water purifiers. In order to solve at least one of the above technical problems, it is necessary to develop a pressure plate, pump chamber structure, diaphragm booster pump, and venting method. Summary of the Invention

[0003] The purpose of this invention is to provide a pressure plate, a pump chamber structure, a diaphragm booster pump, and an exhaust method to solve the above-mentioned technical problems. When the booster pump is installed in reverse, some of the gas in the booster end floats to the surface. Because a first through hole is provided that is connected to the booster end, and its end is close to the side of the booster end away from the water inlet end, the end of the first through hole is close to the space where some of the gas floats, so that some of the gas can be discharged through the first through hole. This solves the problem in the prior art that when the booster pump is installed in reverse or tilted, it takes a long time to discharge the gas.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0005] A pressure plate with venting function includes a pressure plate body, which has a water inlet, a booster end connected to the water inlet, and a water outlet connected to the booster end. The water outlet includes a water outlet seat disposed on the pressure plate body and connected to the booster end. The water outlet seat has a first through hole connected to the booster end, which extends through the booster end along the axial direction of the pressure plate body, with its end close to the side of the booster end away from the water inlet. When the booster pump is in reverse installation, some gas in the booster end floats to the surface. Because of the first through hole connected to the booster end, and its end being close to the side of the booster end away from the water inlet, the end of the first through hole is close to the space where some gas floats, allowing some gas to be discharged through the first through hole. This solves the problem of having to wait a long time for gas to be discharged in the prior art.

[0006] Preferably, one or more first through holes are provided.

[0007] Preferably, the water outlet seat is provided with an extension block extending towards the side of the booster end away from the water inlet end, and the first through hole penetrates through the extension block. A gap is provided between the end of the extension block and the side of the booster end away from the water inlet end, i.e., a gap is provided between the extension block and the diaphragm. By providing the extension block, one end of the first through hole extends to the side of the booster end away from the water inlet end, making it close to the space where some gas floats in the booster chamber of the booster pump in its reversed state. This allows some gas to be discharged through the first through hole, solving the problem in the prior art where a long waiting time is required for gas to be discharged.

[0008] Preferably, the water inlet is located in the middle of one side of the pressure plate body, the pressurization end is located on the other side of the pressure plate opposite to the water inlet, and the water outlet seat is located on the edge of the pressure plate body, with one or more outlet seats arranged around the water outlet. This forms a flow path from the central water inlet to the outer edge water outlet.

[0009] Preferably, the water outlet seat also has a second through hole that can communicate with the booster end. Comparing the positions of the first and second through holes along the radial direction of the pressure plate body, the second through hole is closer to the center of the pressure plate body, while the first through hole is farther from the center. When the booster pump is in the forward direction, some gas can also be discharged from the second through hole into the water outlet chamber, thereby completing the venting process.

[0010] Preferably, the second through holes are symmetrically arranged with the centerline of the water outlet seat as the axis of symmetry. This technical solution uses four symmetrically arranged through holes, with the axis of symmetry passing through the center of the first connecting through hole.

[0011] Preferably, along the axial direction of the pressure plate body, the height of the first through hole extending away from the water inlet end within the pressure boosting end is greater than the height of the second through hole extending away from the water inlet end within the pressure boosting end. This arrangement allows for gas discharge during reverse installation. In the initial state, with the pressure boosting chamber in its upright position as a reference, the pressure boosting end is located below the water inlet end, and the water outlet end is located above the pressure boosting end and on the outer periphery of the water inlet end, forming a state where the pressure boosting end is below, and both the water outlet and water inlet ends are located at the top. The mechanism for pressurizing the pressure boosting end is located below the pressure boosting end. When the pressure boosting pump is in reverse installation, some gas rises and approaches one end of the first through hole, thus allowing it to be discharged from the first through hole. In contrast, in the prior art, in this state, after the gas rises, there is no channel provided to approach the space where the gas rises; only a... The water outlet channel is far from the space where the gas rises. The gas cannot spontaneously cross the sinking liquid in the pressurization chamber and directly reach the second through hole for discharge. It needs to wait for the gas to mix with the liquid during the pressurization process and then be discharged from the second through hole. This will cause the gas to stagnate and not be discharged in time. In this technical solution, since the end of the first through hole is close to the diaphragm, that is, close to the space where the gas rises, it can be directly connected to this place. Therefore, the rising gas can be discharged, and some gas can be discharged through the first through hole, which solves the problem of having to wait a long time for the gas to be discharged in the prior art.

[0012] Preferably, both the first through hole and the extension block are located on the edge of the water outlet seat, away from the center of the pressure plate body in the radial direction. When the booster pump is in reverse installation, the gas rises and concentrates on the side of the booster chamber near the diaphragm and on the outer edge away from the center of the pressure plate. The first through hole is provided at the edge, and the extension block extends the distance of the first through hole in the booster chamber, so that one end of the first through hole is close to the diaphragm, which facilitates the discharge of the gas concentrated at the edge and solves the problem of having to wait a long time to discharge gas in the prior art.

[0013] This technical solution also provides a pump cavity structure, including a pressure plate, an inlet cavity at the inlet end, one or more inlet channels through the inlet cavity, and a second one-way valve connected to the inlet cavity to enable the fluid flow direction in the inlet channel to flow only toward the booster cavity;

[0014] The pressurization end includes one or more pressurization chambers connected to the water inlet channel, and a diaphragm is provided on the side of the pressure plate away from the water inlet chamber in the axial direction to seal the pressurization chamber;

[0015] The water outlet also includes one or more water outlet chambers disposed on the outer periphery of the water inlet chamber. The water outlet seat is disposed on the outer edge of the water inlet chamber. The water outlet seat is provided with a first one-way valve that enables the fluid flow direction in the first through hole and the second through hole to flow only from the pressurization chamber to the water outlet chamber. The multiple water outlet chambers are interconnected. The first one-way valve includes a first connecting end connected to the water outlet seat and a first valve plate fixedly disposed on the first connecting end and fitted against the side of the water outlet seat near the water outlet chamber. The water outlet seat is provided with a first connecting through hole connected to the first connecting end. The first valve plate is fitted against the end of the first through hole near the water outlet chamber and the end of the second through hole near the water outlet chamber. The second one-way valve includes a second connecting end connected to the pressure plate body and a second valve plate fixedly disposed on the second connecting end and fitted against the side of the pressure plate body near the pressurization chamber. The pressure plate body is provided with one or more second connecting through holes at the water inlet chamber that are connected to the second connecting end. The second valve plate is fitted against the end of the water inlet channel near the pressurization chamber.

[0016] This technical solution also provides a diaphragm booster pump, including a pump chamber structure.

[0017] Preferably, the diaphragm booster pump further includes a front cover, a water-pumping bracket, a fixed bracket, a diaphragm, a water-push plate connected to the diaphragm, a die head connected to the fixed bracket and the front cover, and a first sealing ring disposed between the diaphragm and the die head for sealing. The water-push plate is disposed within the booster chamber. The front cover, fixed bracket, and die head are connected by screws, wherein the water-pumping bracket is disposed between the front cover and the diaphragm, the diaphragm is disposed between the fixed bracket and the pressure plate, and the pressure plate is disposed between the die head and the fixed bracket; the first sealing ring improves the sealing performance of the booster pump.

[0018] Preferably, the mold head is equipped with an exhaust valve, which is connected to the water inlet chamber and the water outlet chamber. The exhaust valve has a first channel connected to the water outlet chamber and a second channel connected to the water inlet chamber. The exhaust valve can discharge the gas present in the water outlet chamber and the water inlet chamber.

[0019] This technical solution also provides a method for venting a diaphragm booster pump. The venting method is implemented using the aforementioned diaphragm booster pump and includes the following steps.

[0020] When the diaphragm booster pump is operating in reverse configuration, the booster chamber contains both gas and liquid. Some of the gas rises to the side away from the inlet chamber and is discharged through the first through-hole to the outlet chamber during the booster operation. The outlet chamber is connected to the outlet pipe and the vent valve, thus allowing venting to be completed through the outlet pipe and / or the vent valve. The pumping bracket, diaphragm, and pusher plate pressurize the booster chamber, enabling fluid to flow from the inlet chamber to the booster chamber, and then to the outlet chamber and outlet pipe.

[0021] Preferably, the pressurization chamber contains a mixture of gas and liquid, which is discharged to the water outlet chamber through the second through hole.

[0022] Preferably, the pressurization chamber contains a mixture of gas and liquid, which is discharged to the water outlet chamber through the first through hole.

[0023] Preferably, the exhaust method further includes the following steps:

[0024] When the diaphragm booster pump is operating in its normal configuration, there is gas and liquid in the booster chamber. Some of the gas rises to the side near the inlet chamber. During the booster operation in the booster chamber, the gas is discharged into the outlet chamber through the first and second through holes.

[0025] The pressurization chamber contains a mixture of gas and liquid, which is discharged into the water outlet chamber through the second through hole and the first through hole.

[0026] When the diaphragm booster pump operates horizontally, the booster chamber contains both gas and liquid. Some of the gas rises to a position nearly perpendicular to the horizontal plane within the booster chamber. During the booster operation, the gas is discharged into the outlet chamber through the first and second through holes.

[0027] The pressurization chamber contains a mixture of gas and liquid. This mixture is discharged to the water outlet chamber through the second through hole and the first through hole. The water outlet chamber is connected to the water outlet pipe and the exhaust valve, thereby realizing the exhaust from the water outlet pipe and / or the exhaust valve.

[0028] Preferably, the exhaust method further includes the following steps:

[0029] The gas present in the water inlet chamber is discharged through the exhaust valve.

[0030] This application has achieved beneficial technical effects:

[0031] When the booster pump of the present invention is installed in reverse, some of the gas in the booster end floats to the surface. Because a first through hole is provided that is connected to the booster end, and its end is close to the side of the booster end away from the water inlet end, the end of the first through hole is close to the space where some gas floats to the surface, so that some gas can be discharged through the first through hole. This solves the problem in the prior art that when the booster pump is installed in reverse or tilted, it takes a long time to discharge the gas. Attached Figure Description

Detailed Implementation

[0061] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0062] The technical solution of the present invention will be described in detail below with specific embodiments.

[0063] Reference Figure 1 and 26 The pressure plate shown includes a pressure plate body 10. The pressure plate body 10 is provided with a water inlet end 11, a pressure boosting end 12 connected to the water inlet end 11, and a water outlet end 13 connected to the pressure boosting end 12. The water outlet end 13 includes a water outlet seat 130 disposed on the pressure plate body 10 and connected to the pressure boosting end 12. The water outlet seat 130 is provided with a first through hole 131 connected to the pressure boosting end 12. The first through hole 131 penetrates the pressure boosting end 12 along the axial direction of the pressure plate body 10, and the end of the first through hole 131 is close to the side of the pressure boosting end 12 away from the water inlet end 11. When the booster pump is in reverse installation, some of the gas in the booster end 12 floats to the surface. Because a first through hole 131 is provided that is connected to the booster end 12, and its end is close to the side of the booster end 12 away from the water inlet end 11, the end of the first through hole 131 is close to the space where some of the gas floats. This allows some of the gas to be discharged in a timely manner through the first through hole 131, which solves the problem in the prior art that it takes a long time to discharge gas when the booster pump is reverse installed or tilted.

[0064] One or more first through holes 131 are provided. Specifically, two first through holes are provided on each water outlet seat.

[0065] The water outlet seat 130 is provided with an extension block 132 extending toward the side of the booster end 12 away from the water inlet end 11, and the first through hole 131 penetrates through the extension block 132. A gap 133 is provided between the end of the extension block 132 and the side of the booster end 12 away from the water inlet end 11, that is, a gap 133 is provided between the extension block 132 and the diaphragm. By providing the extension block 132, one end of the first through hole 131 extends to the side of the booster end 12 away from the water inlet end 11, making it close to the space where some gas in the booster chamber of the booster pump in the reversed state floats upwards. This allows some gas to be discharged through the first through hole 131, solving the problem of having to wait a long time for gas to be discharged in the prior art.

[0066] The water inlet 11 is located in the middle of one side of the pressure plate body 10, the pressure boosting end 12 is located on the other side of the pressure plate opposite to the water inlet 11, and the water outlet seat 130 is located on the edge of the pressure plate body 10. The water outlet seat 10 has one or more components arranged around the water outlet end. This forms a flow path with water inlet in the middle and water outlet at the outer edge.

[0067] The water outlet seat 10 is also provided with a second through hole 134 that can communicate with the booster end 12. Comparing the positions of the first through hole 131 and the second through hole 134 along the radial direction of the pressure plate body 10, the second through hole 134 is closer to the center of the pressure plate body 10, while the first through hole 131 is farther from the center of the pressure plate body 10. When the booster pump is in the forward direction, some gas can also be discharged from the second through hole 134 into the water outlet chamber, thereby completing the venting process.

[0068] The second through hole 134 is symmetrically arranged with the center line of the water outlet seat 130 as the axis of symmetry. This technical solution involves four symmetrically arranged through holes, with the axis of symmetry passing through the center of the first connecting through hole.

[0069] Along the axial direction of the pressure plate body 10, the height X of the first through hole 131 extending away from the water inlet 11 within the pressure boosting end 12 is greater than the height Y of the second through hole 134 extending away from the water inlet 11 within the pressure boosting end 12. This arrangement allows for the discharge of gas during reverse installation. In the initial state, with the pressure boosting chamber in its normal position as a reference, the pressure boosting end is located below the water inlet, and the water outlet 13 is located above the pressure boosting end and on the outer periphery of the water inlet 11, forming a state where the pressure boosting end 12 is below, and both the water outlet 31 and the water inlet 11 are located at the top. The mechanism for pressurizing the pressure boosting end 12 is located below the pressure boosting end 13. When the booster pump is in reverse installation, some gas rises and approaches one end of the first through hole 131, thus allowing it to be discharged from the first through hole 131. In the prior art, in this state, after the gas rises, there is no channel provided to approach the space where the gas rises. In the previous method, only a water outlet channel was set away from the space where the gas floated. However, the gas could not spontaneously cross the sinking liquid in the pressurization chamber and directly reach the second through hole 134 for discharge. It had to wait for the gas to be mixed with the liquid during the pressurization process before it could be discharged from the second through hole 134. This caused the gas to stagnate and not be discharged in time. In this technical solution, since the end of the first through hole 131 is close to the diaphragm, that is, close to the space where the gas floats, it can be directly connected to this space. Therefore, the floating gas can be discharged, and some gas can be discharged through the first through hole 131, which solves the problem of having to wait a long time for the gas to be discharged in the prior art.

[0070] The first through hole 131 and the extension block 132 are both located on the edge of the water outlet seat 130, away from the center of the pressure plate body 10 in the radial direction. When the booster pump is in reverse installation, the gas rises and concentrates more on the side of the booster chamber near the diaphragm and away from the center of the pressure plate 1. The first through hole 131 is provided at the edge, and the extension block 132 extends the extension distance of the first through hole 131 in the booster chamber, so that one end of the first through hole 131 is close to the diaphragm, which facilitates the discharge of the gas concentrated at the edge and solves the problem of having to wait a long time to discharge gas in the prior art.

[0071] This technical solution also provides a pump cavity structure, including a pressure plate 1, an inlet cavity 111 provided at the inlet end 11, one or more inlet channels 112 provided through the inlet cavity 111, and a second one-way valve 136 connected to the inlet cavity 111 to enable the fluid flow direction in the inlet channel 112 to flow only toward the booster cavity 121.

[0072] The pressurization end 12 includes one or more pressurization chambers 121 that communicate with the water inlet channel 112.

[0073] The water outlet 13 also includes one or more water outlet chambers 135 disposed on the outer periphery of the water inlet chamber 111. The water outlet seat 130 is disposed on the outer edge of the water inlet chamber 111. The water outlet seat 130 is provided with a first one-way valve 113 that enables the fluid flow direction in the first through hole 131 and the second through hole 134 to flow only from the pressurization chamber 12 to the water outlet chamber 135. The water outlet cavity 135 is disposed between the mold head and the pressure plate body 10; multiple water outlet cavities 135 are interconnected; wherein the first one-way valve 113 includes a first connecting end 1131 connected to the water outlet seat and a first valve plate 1132 fixedly disposed on the first connecting end 1131 and attached to the side of the water outlet seat near the water outlet cavity 135, wherein the water outlet seat 130 is provided with a first connecting through hole 1133 connected to the first connecting end 1131, and the first valve plate 1132 is attached to the end of the first through hole 131 near the water outlet cavity 135 and the end of the second through hole 134 near the water outlet cavity 135. The second one-way valve 136 includes a second connecting end 1361 connected to the pressure plate body 10 and a second valve plate 1362 fixedly disposed on the second connecting end 1361 and attached to the side of the pressure plate body near the pressurization chamber 121. The pressure plate body 10 is provided with one or more second connecting through holes 1363 connected to the second connecting end 1361 at the water inlet chamber 111. In this technical solution, four second connecting through holes 1363 are specifically provided, and the number of them corresponds to the number of the second one-way valve. The second valve plate 1362 is attached to the end of the water inlet channel 112 near the pressurization chamber 121.

[0074] The first valve plate 1132 is provided with a first capping end 1134 that covers the first through hole 131 and a second capping end 1135 that covers the second through hole.

[0075] The water outlet seat 130 has a first notch 138 on its outer edge away from the pressure plate body 10. The first notch 138 provides more space for the first through hole 131 to vent during the venting process, improves the venting efficiency, and facilitates the drilling operation of the first through hole 131 during the manufacturing process, allowing the drilling equipment to be closer to the water outlet seat 130 for drilling operation.

[0076] This technical solution also provides a diaphragm booster pump, characterized by including a pump cavity structure.

[0077] The diaphragm booster pump also includes a front cover 2, a water-pumping bracket 3, a fixed bracket 4, a diaphragm 5, a water-push plate 6 connected to the diaphragm 5, a die head 8 connected to the fixed bracket 4 and the front cover 2, and a first sealing ring 7 disposed between the diaphragm 5 and the die head 8 for sealing. The radial direction of the first sealing ring 7 abuts against the outer radial edge of the pressure plate 1 and the inner radial surface of the die head 8. The diaphragm 5 is disposed on the side of the pressure plate 1 away from the water inlet cavity 111 in the axial direction to seal the booster cavity 121. The water-push plate 6 is partially disposed within the booster cavity 121 and connected to the water-pumping bracket 4 by screws. In the overall structure of the booster pump, the front cover 2, the fixed bracket 4, and the die head 5 are connected by screws. The water-pumping bracket 3 is disposed between the front cover 2 and the diaphragm 5, the diaphragm 5 is disposed between the fixed bracket 4 and the pressure plate 1, and the pressure plate 1 is disposed between the die head 8 and the fixed bracket 4. The first sealing ring 7 improves the sealing performance of the booster pump.

[0078] The mold head 8 is equipped with an exhaust valve 9, which is connected to the water inlet chamber 111 and the water outlet chamber 135. The exhaust valve 9 has a first channel 91 connected to the water outlet chamber 135 and a second channel 92 connected to the water inlet chamber 111. The exhaust valve 9 can discharge the gas present in the water outlet chamber 135 and the water inlet chamber 111.

[0079] This technical solution also provides a method for venting a diaphragm booster pump. The venting method is implemented using the aforementioned diaphragm booster pump and includes the following steps.

[0080] When the diaphragm booster pump is in reverse operation, the booster chamber 121 contains gas and liquid. Some of the gas rises to the side away from the inlet chamber 111 within the booster chamber 121. During the booster operation within the booster chamber 121, the gas is discharged through the first through-hole 131 to the outlet chamber 135. The outlet chamber 135 is connected to the outlet pipe and the vent valve 9, thereby enabling venting from the outlet pipe 82 and / or the vent valve. The water pump bracket 3, diaphragm 5, and pusher 6 enable the booster chamber 121 to perform booster operation, allowing fluid to flow from the inlet chamber 111 to the booster chamber 121, and then to the outlet chamber 135 and the outlet pipe 82.

[0081] The pressurization chamber 121 contains a mixture of gas and liquid, which is discharged to the water outlet chamber through the second through hole 134.

[0082] The pressurization chamber 121 contains a mixture of gas and liquid, which is discharged to the water outlet chamber 111 through the first through hole 131.

[0083] The exhaust method also includes the following steps:

[0084] When the diaphragm booster pump is in normal operation, the booster chamber 121 contains gas and liquid. Some of the gas rises in the booster chamber 121 to the side near the inlet chamber 111. During the pressurization operation in the booster chamber 121, the gas is discharged to the outlet chamber 111 through the first through hole 131 and the second through hole 134.

[0085] The pressurization chamber 121 contains a mixture of gas and liquid, which is discharged to the outlet chamber 111 through the second through hole 134 and the first through hole 131. When the diaphragm booster pump operates horizontally, the pressurization chamber 121 contains both gas and liquid. Some of the gas rises in the pressurization chamber 121 to a position close to its vertical position above the horizontal plane. During the pressurization process in the pressurization chamber 121, the gas is discharged to the outlet chamber 111 through the first through hole 131 and the second through hole 134.

[0086] The pressurization chamber 121 contains a mixture of gas and liquid. This mixture is discharged to the water outlet chamber 111 through the second through hole 134 and the first through hole 131. The water outlet chamber 111 is connected to the water outlet pipe 82 and the exhaust valve 9, thereby realizing the exhaust from the water outlet pipe 82 and / or the exhaust valve 9.

[0087] The exhaust method also includes the following steps:

[0088] The gas present in the water inlet chamber 111 is discharged from the exhaust valve 9.

[0089] The reverse installation is defined as the direction from the water inlet chamber 111 to the pressurization chamber 121 being directly upward or obliquely upward (i.e., the pressurization chamber 121 is located above the water inlet chamber 111), and the forward installation is defined as the direction from the water inlet chamber 111 to the pressurization chamber 121 being directly downward or obliquely downward (i.e., the pressurization chamber 121 is located below the water inlet chamber 111); the water inlet pipe 81 is connected to the water inlet chamber 111, and the water outlet pipe 82 is connected to the water outlet chamber 135; the fluid includes water, gas, or a mixture thereof; a sealing part, specifically a second sealing ring, is provided between the water outlet chamber 135 and the water inlet chamber 111.

[0090] To address the technical problem of rapid venting in existing technologies, this technical solution improves the four water inlet seats of the pressure plate by adding a first through hole to achieve rapid venting.

[0091] In this technical solution, an edge vent hole is added to the four-chamber pressure plate, that is, the first through hole is set on the four water inlet seats of the pressure plate. The water inlet seats are set at the four corners of the pressure plate. The pump body can complete the rapid venting at 360 degrees. That is, whether it is installed in the forward or reverse direction, the rapid venting can be achieved, thereby achieving the functional structure of instantaneous venting.

[0092] The adjustable pressure stabilizing and relieving structure of the pump head, namely the exhaust valve and the pressure plate forming a one-way channel with a closed relationship between high and low pressure, achieves the high-pressure explosion exhaust effect in a small space.

[0093] This technical solution reduces the volume of the pump head cavity, thus reducing the space for gas storage and making it less prone to bubble formation. It also allows for immediate high-pressure water output. By reducing the volume of the pump head cavity, there is no extra space for gas to remain, while additional edge vents allow for rapid venting.
