Description

Technical Field

[0001] The invention relates to the technical field of diaphragm pump equipment, in particular to an electric diaphragm pump with four diaphragm chambers. Background Art

[0002] The working principle of the electric diaphragm pump is that the eccentric wheel and the large bearing are driven to rotate eccentrically by the reducer main shaft, and the pump body skeleton connecting rod shaft is driven to reciprocate by the eccentric wheel and the large bearing. The diaphragms on the left and right ends of the connecting rod shaft follow the left and right reciprocating motion, and two sets of upper and lower one-way ball valves are installed in the left and right pump chambers. The left and right movement of the diaphragm causes the volume in the pump chamber to change regularly, forcing the four one-way ball valves to open and close alternately, thereby sucking in and discharging the liquid to produce fluid.

[0003] Among them, if the pump still generates pressure when the discharge port is blocked or closed, the pressure will eventually act on the pump diaphragm or the pump chamber and pump casing, eventually causing the pump diaphragm or the pump chamber and pump casing to burst, causing damage to the equipment. In response to the above problems, the following solutions are proposed. Summary of the invention

The driving mechanism comprises: A power assembly is fixedly arranged on the inner wall of the housing to transmit the power generated by the motor to the inside of the housing; A circulation component, which is arranged through the side wall of the shell and is used to squeeze the external water flow; The power generated by the motor drives the pressure mechanism and the separation mechanism to operate through the power component, so that the water inside the circulation component flows.

[0006] Preferably, the pressure applying mechanism comprises: A transmission component, which is fixedly arranged on the inner wall of the housing through a sliding member and is used to convert the rotation force of the motor into a left-right sliding force; The sliding member comprises two sliding rods fixedly arranged on the inner wall of the housing, a sliding plate is slidably connected to the outer wall of the two sliding rods, a sliding square rod is fixedly connected to the side wall of the sliding plate, and the other end of the sliding square rod is slidably connected to the inner wall of the pressure block; When the motor rotates through the power assembly, the power assembly forces the slide plate to slide along the outer wall of the sliding rod.

[0007] Preferably, the pressure applying mechanism further comprises: A linkage component, which is opened on the inner wall of the pressure block through a storage component and is used to drive the circulation component to apply pressure; The storage element comprises a second cavity opened on the side wall of the pressure block, a first cavity opened on the inner wall of the pressure block, and a first slide groove opened on the top of the pressure block; Among them, cavity two is in contact with the external water body and stores part of the water body, cavity two is in a state of interconnection with chute one, and cavity one is not in communication with cavity two.

[0009] Preferably, the power assembly includes a drive shaft fixedly connected to the output shaft of the motor, and an eccentric shaft is fixedly connected to the outer wall of the drive shaft; The installation position of the eccentric shaft is not at the center position of the driving shaft. When the driving shaft rotates, the eccentric shaft slides the inner wall of the through hole groove and pushes the slide plate to slide along the outer wall of the sliding rod.

[0010] Preferably, the circulation component includes a shell connected through both sides of the shell, a diaphragm is fixedly connected to the inner wall of the shell, a transmission pipe is connected through one end of the shell away from the shell, four water inlet check valves are connected through the inner wall of the transmission pipe, a water inlet is connected through the bottom of the transmission pipe, and a drain is connected through the side wall of the transmission pipe; Before use, the external water pipe is connected to the water inlet, and when the slide plate moves horizontally left and right, the pressure block will force the diaphragm to apply pressure to the water inside the transmission pipe.

[0011] The transmission component includes a through hole groove opened on the inner wall of the slide plate, and a mounting groove is opened on the outer wall of the pressure block to ensure that the through hole of the diaphragm is fixedly connected to the inner wall of the mounting groove; When the water pressure inside the transmission pipe gradually decreases, the piston block will carry the sliding plate downward. If the fixed plate is in Figure 7 When the sliding plate is in the state, the sliding plate slides downward, and the fixed plate will be between the sliding plate and the support frame again; when the fixed plate is in Figure 8 When the sliding plate is in the right position, as the U-shaped rod drives the sliding plate downward, the fixed plate moving left and right will contact the curved surface of the sliding plate and force the sliding plate to slide upward along the inner wall of the groove of the U-shaped rod. At this time, the fixed plate will be in the gap between the sliding plate and the support frame again. Through the application of the above components, it is ensured that the internal components of the equipment can be quickly reset and continue to work after the external water pressure disappears.

[0012] Preferably, the linkage assembly includes a piston block slidably connected to the inner wall of the slide groove 1, the top of the piston block is fixedly connected to a U-shaped rod, the top of the pressure block is fixedly connected to a sliding column, the outer wall of the sliding column is slidably connected to the inner wall of the through hole of the U-shaped rod, the top of the pressure block is fixedly connected to a spring 1, one end of the spring 1 away from the pressure block is fixedly connected to the bottom of the U-shaped rod, and a slide groove 2 is provided on the outer wall of the pressure block; Among them, when the water pressure inside cavity two is too high, the water pressure will push the piston block to slide upward along the inner wall of slide groove one, and drive the U-shaped rod to slide upward synchronously. When the drain outlet is blocked, the water pressure inside the transmission pipe will increase, and the pressure will act evenly on the outer wall of the contact component. When the pressure is too large, the internal pressure of cavity two will increase synchronously, and the piston block will slide upward along the inner wall of slide groove one. The upward slide groove one will drive the U-shaped rod to slide upward along the inner wall of the sliding column. At this time, spring one will extend and accumulate mechanical power.

[0013] Preferably, the contact assembly includes a sliding plate slidably connected to the inner wall of the groove on the side wall of the U-shaped rod, a spring three is fixedly connected to the outer wall of the sliding plate, one end of the spring three away from the sliding plate is fixedly connected to the inner wall of the U-shaped rod groove, and one end of the pressure block away from the cavity two is fixedly connected to the support frame, wherein the side wall of the sliding plate is provided with an arc surface, and as the U-shaped rod moves upward, the U-shaped rod drives the sliding plate to move upward synchronously through the spring three, so that the sliding plate no longer contacts the outer wall of the fixed plate, and the slide plate generates a lateral force at this time, which will drive the pressure column and the fixed plate to enter the inner wall of the cavity one, so that the device moves from Figure 7 The state of turning Figure 8 At this time, the thrust generated by the fixed plate will not be able to drive the pressure block to continue to move horizontally, so that the pressure block and the diaphragm stop applying pressure, avoiding excessive pressure inside the transmission tube, resulting in rupture of the diaphragm or the transmission tube; When the U-shaped rod moves upward, the sliding plate will be driven to move upward synchronously, so that the outer wall of the fixed plate is no longer in contact with the plane of the sliding plate.

[0014] Preferably, the balancing assembly comprises a gear rod fixedly connected to the side walls of the upper and lower U-shaped rods, and the outer wall of the gear rod is meshedly connected with the outer wall of the gear; Among them, when the water pressure inside cavity two is too high, the two U-shaped rods will move outward and drive the corresponding gear rods to move outward synchronously. When the two U-shaped rods are affected by the water pressure and slide outward, the U-shaped rods will drive the corresponding gear rods to slide outward, and the two gear rods that move outward will rotate the same gear. Through the application of the above components, the gear will limit the length and speed of the two gear rods sliding outward, ensuring that the contraction efficiency of the two U-shaped rods is equal, avoiding the two sliding plates from being subjected to different pressures due to the different upper and lower positions, and ultimately resulting in unequal contraction speeds, causing the fixed plate to contact one of the sliding plates, resulting in uneven force.

[0015] The present invention has the following beneficial effects: (1) The present invention utilizes the problem that the pressure inside the device increases when the water outlet is blocked. A pressure mechanism and a separation mechanism are arranged inside the device. When the water outlet is blocked, the internal water pressure of cavity 2 will increase synchronously, and the piston block will slide upward along the inner wall of the slide groove 1. The U-shaped rod drives the sliding plate to move upward synchronously through the spring 3, so that the sliding plate no longer contacts the outer wall of the fixed plate. At this time, the slide plate generates a lateral force, which will drive the pressure column and the fixed plate to enter the inner wall of cavity 1, so that the device can be discharged from the cavity 1. Figure 7 The state of turning Figure 8 state, at this time the thrust generated by the fixed plate will not be able to drive the pressure block to continue to move horizontally, so that the pressure block and the diaphragm stop applying pressure, avoiding excessive pressure inside the transmission tube, which may cause the diaphragm or the transmission tube to rupture.

[0016] (2) The present invention separates the sliding plate from the support frame and ensures that there is a distance between the plane of the sliding plate and the inner wall of the support frame. When the side wall of the fixed plate contacts the side wall of the sliding plate, the sliding plate does not contact the inner wall of the support frame. When the side wall of the fixed plate contacts the inner wall of the support frame, the side wall of the fixed plate will no longer contact the side wall of the sliding plate. Through the application of the above-mentioned components, it is avoided that after the piston block is subjected to sufficient water pressure, the power required for the fixed plate to push the sliding plate is too large, resulting in excessive contact resistance between the fixed plate and the sliding plate, which affects the piston block from driving the U-shaped rod to move upward, causing the equipment to fail to operate normally.

[0017] (3) In the present invention, after the water pressure inside the transmission pipe gradually decreases, the piston block will carry the sliding plate to slide downward. If the fixed plate is in Figure 7 When the sliding plate is in the state, the sliding plate slides downward, and the fixed plate will be between the sliding plate and the support frame again; when the fixed plate is in Figure 8When the sliding plate is in the right position, as the U-shaped rod drives the sliding plate downward, the fixed plate moving left and right will contact the curved surface of the sliding plate and force the sliding plate to slide upward along the inner wall of the groove of the U-shaped rod. At this time, the fixed plate will be in the gap between the sliding plate and the support frame again. Through the application of the above components, it is ensured that the internal components of the equipment can be quickly reset and continue to work after the external water pressure disappears.

[0018] (4) In the present invention, when the two U-shaped rods are affected by water pressure and slide outward, the U-shaped rods will drive the corresponding gear rods to slide outward, and the two gear rods that move outward will rotate the same gear. Through the application of the above-mentioned components, the gear will limit the length and speed of the two gear rods sliding outward, ensuring that the contraction efficiency of the two U-shaped rods is equal, avoiding the two sliding plates from being subjected to different pressures due to their different upper and lower positions, and ultimately resulting in unequal contraction speeds, resulting in the fixed plate contacting one of the sliding plates, causing uneven force.

[0026] The pressure applying mechanism 2 also includes: The linkage component 22 is provided on the inner wall of the pressure block 215 through a storage member, and is used to drive the circulation component 12 to apply pressure; The storage element includes a second cavity 222 opened on the side wall of the pressure block 215, a first cavity 221 opened on the inner wall of the pressure block 215, and a first slide groove 223 opened on the top of the pressure block 215; The second cavity 222 contacts with the external water body and stores part of the water body. The second cavity 222 and the first chute 223 are in a state of intercommunication, while the first cavity 221 and the second cavity 222 are not intercommunication.

[0027] Disengagement from institution 3 includes: The contact assembly 31 is fixedly disposed on the side wall of the slide plate 212 through a connecting piece, and is used to transmit the force of the slide plate 212 moving horizontally to the inside of the disengagement mechanism 3; The connecting member includes a pressure column 311 fixedly connected to the side wall of the slide plate 212, and one end of the pressure column 311 away from the slide plate 212 is fixedly connected to a fixing plate 312; A balancing component 32, which is rotatably connected to the side wall of the pressure block 215 through a rotating member, and is used for balancing the operation of the linkage component 22; The rotating member includes a gear 322 rotatably connected to the side wall of the pressure block 215; When the linkage assembly 22 is pressed and moves, the gear 322 will limit the outward movement length of the upper and lower linkage assemblies 22 .

[0028] For example 2, please refer to Figure 3 - Fig.10The present invention is an electric diaphragm pump with four diaphragm chambers. Based on Example 1, the power assembly 11 includes a drive shaft 112 fixedly connected to the output shaft of the motor 111, and an eccentric shaft 113 is fixedly connected to the outer wall of the drive shaft 112; The installation position of the eccentric shaft 113 is not at the center position of the driving shaft 112. When the driving shaft 112 rotates, the eccentric shaft 113 slides the inner wall of the through hole groove 213 and pushes the slide plate 212 to slide along the outer wall of the sliding rod 211. The circulation component 12 includes a shell 121 connected to both sides of the shell 13, a diaphragm 122 is fixedly connected to the inner wall of the shell 121, a transmission pipe 123 is connected to the end of the shell 121 away from the shell 13, four water inlet check valves 124 are connected to the inner wall of the transmission pipe 123, a water inlet 125 is connected to the bottom of the transmission pipe 123, and a drain port 126 is connected to the side wall of the transmission pipe 123; Before use, the external water pipe is connected to the water inlet 125 , and when the slide plate 212 moves horizontally to the left and right, the pressure block 215 will force the diaphragm 122 to apply pressure to the water inside the transmission pipe 123 .

[0029] The transmission component 21 includes a through hole groove 213 provided on the inner wall of the slide plate 212, and a mounting groove 216 is provided on the outer wall of the pressure block 215 to ensure that the through hole of the diaphragm 122 is fixedly connected to the inner wall of the mounting groove 216; When the water pressure inside the transmission pipe 123 gradually decreases, the piston block 224 will carry the sliding plate 313 to slide downward. Figure 7 When the sliding plate 313 slides downward, the fixed plate 312 will be between the sliding plate 313 and the support frame 315 again; when the fixed plate 312 is in Figure 8 When the U-shaped rod 225 is in the sliding position, the U-shaped rod 225 drives the sliding plate 313 to move downward, and the fixed plate 312 moving left and right will contact the curved surface of the sliding plate 313 and force the sliding plate 313 to slide upward along the inner wall of the groove of the U-shaped rod 225. At this time, the fixed plate 312 will be in the gap between the sliding plate 313 and the support frame 315 again. Through the application of the above components, it is ensured that the internal components of the equipment can be quickly reset and continue to work after the external water pressure disappears.

[0030] The linkage assembly 22 includes a piston block 224 slidably connected to the inner wall of the slide groove 1 223, a U-shaped rod 225 is fixedly connected to the top of the piston block 224, a sliding column 226 is fixedly connected to the top of the pressure block 215, the outer wall of the sliding column 226 is slidably connected to the inner wall of the through hole of the U-shaped rod 225, a spring 1 227 is fixedly connected to the top of the pressure block 215, one end of the spring 1 227 away from the pressure block 215 is fixedly connected to the bottom of the U-shaped rod 225, and a slide groove 228 is provided on the outer wall of the pressure block 215; Among them, when the water pressure inside cavity 222 is too high, the water pressure will push the piston block 224 to slide upward along the inner wall of slide groove 1 223, and drive the U-shaped rod 225 to slide upward synchronously. When the drain outlet 126 is blocked, the water pressure inside the transmission pipe 123 will increase, and the pressure will act evenly on the outer wall of the contact component. When the pressure is too high, the internal pressure of cavity 222 will increase synchronously, and the piston block 224 will slide upward along the inner wall of slide groove 1 223. The upward slide groove 1 223 will drive the U-shaped rod 225 to slide upward along the inner wall of the sliding column 226. At this time, the spring 1 227 will extend and accumulate mechanical power.

[0031] The contact assembly 31 includes a sliding plate 313 slidably connected to the inner wall of the groove of the side wall of the U-shaped rod 225, and a spring three 314 is fixedly connected to the outer wall of the sliding plate 313. The end of the spring three 314 away from the sliding plate 313 is fixedly connected to the inner wall of the groove of the U-shaped rod 225, and the end of the pressure block 215 away from the cavity 222 is fixedly connected to the support frame 315, wherein the side wall of the sliding plate 313 is provided with an arc surface. As the U-shaped rod 225 moves upward, the U-shaped rod 225 drives the sliding plate 313 to move upward synchronously through the spring three 314, so that the sliding plate 313 is no longer in contact with the outer wall of the fixed plate 312. At this time, the slide plate 212 generates a lateral force, which will drive the pressure column 311 and the fixed plate 312 to enter the inner wall of the cavity 1 221, so that the device is moved from Figure 7 The state of turning Figure 8 In this state, the thrust generated by the fixed plate 312 will not be able to drive the pressure block 215 to continue to move horizontally, so that the pressure block 215 and the diaphragm 122 stop applying pressure, thereby preventing the internal pressure of the transmission tube 123 from being too high, resulting in the rupture of the diaphragm 122 or the transmission tube 123; When the U-shaped rod 225 moves upward, the sliding plate 313 will be driven to move upward synchronously, so that the outer wall of the fixed plate 312 is no longer in contact with the plane of the sliding plate 313 .

[0032] The balancing assembly 32 includes a gear rod 321 fixedly connected to the side walls of the upper and lower U-shaped rods 225, and the outer wall of the gear rod 321 is meshedly connected with the outer wall of the gear 322; Among them, when the water pressure inside the second cavity 222 is too high, the two U-shaped rods 225 will move outward and drive the corresponding gear rods 321 to move outward synchronously. When the two U-shaped rods 225 are affected by the water pressure and slide outward, the U-shaped rods 225 will drive the corresponding gear rods 321 to slide outward, and the two outward-moving gear rods 321 will rotate the same gear 322. Through the application of the above-mentioned components, the gear 322 will limit the length and speed of the two gear rods 321 sliding outward, ensuring that the contraction efficiency of the two U-shaped rods 225 is equal, avoiding the two sliding plates 313 from being subjected to different pressures due to the different upper and lower positions, and finally resulting in unequal contraction speeds, resulting in the fixed plate 312 contacting one of the sliding plates 313, causing uneven force.

[0033] A specific application of this embodiment is: before use, the external water inlet pipe is connected to the water inlet 125, the water outlet pipe is connected to the drain outlet 126, and then the power of the motor 111 is turned on. The motor 111 will drive the drive shaft 112 to rotate. Since the eccentric shaft 113 is not at the center position of the drive shaft 112, when the drive shaft 112 rotates, the eccentric shaft 113 will drive the slide plate 212 to move left and right along the outer wall of the sliding rod 211 through the through hole groove 213, and the slide plate 212 that acts to move horizontally drives the fixed plate 312 to move left and right synchronously through the pressure column 311 The fixed plate 312 moves horizontally, and the fixed plate 312 contacts the outer wall of the sliding plate 313. The fixed plate 312 will push the sliding plate 313 and the pressure block 215 to move outward, and when the pressure column 311 is reset, the fixed plate 312 contacts the inner wall of the support frame 315. The fixed plate 312 drives the pressure block 215 to reset along the outer wall of the sliding square rod 214 through the support frame 315. During this movement, as the diaphragm 122 squeezes the water inside the transmission pipe 123, the water inside the transmission pipe 123 will be discharged from the water outlet 126 through the water inlet check valve 124. When the drain port 126 is blocked, the water pressure inside the transmission pipe 123 will increase, and the pressure will act evenly on the outer wall of the contact component. When the pressure is too high, the internal pressure of the cavity 222 will increase synchronously, and the piston block 224 will slide upward along the inner wall of the slide groove 1 223. The upward slide groove 1 223 will drive the U-shaped rod 225 to slide upward along the inner wall of the sliding column 226. At this time, the spring 1 227 will extend and accumulate mechanical power; as the U-shaped rod 225 moves upward, the U-shaped rod 225 drives the sliding plate 313 to move upward synchronously through the spring 314, so that the sliding plate 313 no longer contacts the outer wall of the fixed plate 312. At this time, the slide plate 212 generates a lateral force, which will drive the pressure column 311 and the fixed plate 312 to enter the inner wall of the cavity 1 221, so that the device can be moved upward. Figure 7 The state of turning Figure 8state, at this time, the thrust generated by the fixing plate 312 will not be able to drive the pressure block 215 to continue to move horizontally, so that the pressure block 215 and the diaphragm 122 stop applying pressure, thereby preventing the internal pressure of the transmission tube 123 from being too high, resulting in the rupture of the diaphragm 122 or the transmission tube 123.

[0034] Among them, there is a distance between the plane of the sliding plate 313 and the inner wall of the support frame 315. When the side wall of the fixed plate 312 contacts the side wall of the sliding plate 313, the sliding plate 313 does not contact the inner wall of the support frame 315. When the side wall of the fixed plate 312 contacts the inner wall of the support frame 315, the side wall of the fixed plate 312 will no longer contact the side wall of the sliding plate 313. Through the application of the above-mentioned components, it is avoided that after the piston block 224 is subjected to sufficient water pressure, the power required for the fixed plate 312 to push the sliding plate 313 is too large, resulting in excessive contact resistance between the fixed plate 312 and the sliding plate 313, which affects the piston block 224 to drive the U-shaped rod 225 to move upward, causing the equipment to fail to operate normally.

[0035] When the water pressure inside the transmission pipe 123 gradually decreases, the piston block 224 will carry the sliding plate 313 to slide downward. Figure 7 When the sliding plate 313 slides downward, the fixed plate 312 will be between the sliding plate 313 and the support frame 315 again; when the fixed plate 312 is in Figure 8 When the U-shaped rod 225 is in the sliding position, the U-shaped rod 225 drives the sliding plate 313 to move downward, and the fixed plate 312 moving left and right will contact the curved surface of the sliding plate 313 and force the sliding plate 313 to slide upward along the inner wall of the groove of the U-shaped rod 225. At this time, the fixed plate 312 will be in the gap between the sliding plate 313 and the support frame 315 again. Through the application of the above components, it is ensured that the internal components of the equipment can be quickly reset and continue to work after the external water pressure disappears.

[0036] When the two U-shaped rods 225 are affected by the water pressure and slide outward, the U-shaped rods 225 will drive the corresponding gear rods 321 to slide outward, and the two outward-moving gear rods 321 will rotate the same gear 322. Through the application of the above components, the gear 322 will limit the length and speed of the two gear rods 321 sliding outward, thereby ensuring that the two U-shaped rods 225 have equal contraction efficiency, avoiding the two sliding plates 313 from being subjected to different pressures due to different upper and lower positions, and ultimately resulting in unequal contraction speeds, resulting in the fixed plate 312 contacting one of the sliding plates 313, causing uneven force.
