[0016] A method for using a multi-stage booster pump comprises the following steps:

[0017] S1: The motor drives the pumping device inside the water inlet and the booster device inside the pump body to operate, pumping water into the pump body for boosting, and then spraying water into the outlet pipe through the outlet pipe connection frame;

[0018] S2: The pressurized water enters the extended water outlet tube and the water collecting box, and the pressurized water flow continues to accumulate inside the water outlet butt joint pipe and the extended water outlet tube. When the pressure inside the water outlet butt joint pipe and the extended water outlet tube is greater than the elastic force of the pressurizing spring, the extended water outlet tube will slide inside the limit slideway on the inner wall of the water outlet butt joint pipe, so that the water outlet butt joint pipe extends outward;

[0019] S3: At the same time, the sliding limit connecting ring is driven to pass through multiple sliding holes and slide on the outer wall of the water outlet butt joint pipe, and the booster spring is stretched. When the pumping speed of the stable slide bar and the pumping device inside the water inlet is too slow, the water is pressurized by the pump body and enters the water outlet butt joint pipe and the extended water outlet cylinder, and is pressurized twice before the water is discharged;

[0020] S4: When the extended water cylinder drives the water collection box to move to a suitable distance, the connecting pipe required for use will be automatically opened to spray out the pressurized water.

[0021] The present invention has the following beneficial effects:

[0022] The present invention connects a side of the water inlet away from the pump body with the connecting back plate, connects the polygonal connecting column at the output end of the motor with the polygonal groove on the water pumping device inside the water inlet, and fixes the pump body to the main body and the connecting back plate by bolts. The motor drives the water pumping device inside the water inlet and the booster device inside the pump body to operate. After water is pumped into the pump body for boosting, it is sprayed into the inside of the water outlet butt joint pipe through the water outlet pipe connecting frame, so that the boosted water enters the inside of the extended water outlet cylinder and the water collecting box. The boosted water flow continues to accumulate in the water outlet butt joint pipe and the extended water outlet cylinder. When the pressure inside the water outlet butt joint pipe and the extended water outlet cylinder is greater than The elastic force of the booster spring will drive the extended water outlet cylinder to slide inside the limiting slideway on the inner wall of the water outlet pipe, so that the water outlet pipe extends outward, and at the same time drives the sliding limiting connecting ring to pass through multiple sliding holes to slide on the outer wall of the water outlet pipe, and stretch the booster spring. When the pumping speed of the stabilizing slide bar and the water pumping device inside the water inlet is too slow, the water can be pressurized through the pump body and enter the water outlet pipe and the extended water outlet cylinder, and then be pressurized for the second time before the water is discharged, thereby improving the pressurization effect, thereby avoiding the intermittent spraying of water due to the large opening of the water outlet pipe connecting frame of the pump body, thereby affecting the pressurization effect of the booster pump.

[0023] When a plurality of connecting pipes are connected to an external water spray pipe of the present invention, before the operation of the device, the plug column is manually controlled by the control handle to slide inside the limit sliding hole strip, so that the plug column is inserted into the limit plug hole, and the sliding bar is driven to rise, so that the plug block leaves the contraction groove block, and when the extended water outlet cylinder slides inside the water outlet butt joint pipe, the control pull bar is pulled to slide inside the strip hole through the blocking plug plate frame, and when the control pull bar abuts against one end of the limit sliding hole strip inside the strip hole and the extended water outlet cylinder drives the water collecting box to move continuously, a pulling force is generated on the blocking plug plate frame, so that the blocking plug plate frame moves toward the inside of the plug hole The closure of the water pipe is connected to the outer wall of the water collecting box, and the closure of the water collecting box is closed by pulling the closure outward, thereby opening a connecting pipe connected to the water spray pipe and the water collecting box. Not only can the extended water outlet cylinder and the water outlet butt pipe not be pressurized continuously, causing water to spray out through the connecting pipe and the water collecting box due to pressure, but the device can also be connected to multiple water spray pipes at the same time, thereby improving the practicality of the device. When the extended water outlet cylinder drives the water collecting box to move to a suitable distance to perform secondary pressurization on the water inside, the connecting pipe that needs to be used will be automatically opened to spray out the pressurized water, and the opening of the connecting pipe to the sealing plate frame will change with the size of the water flow.

[0024] When the sealing plug plate frame slides outward in the insertion hole, it will drive the sliding frame to slide in the shrinkage slot block and squeeze the extrusion spring, so that after the force between the control pull bar and the inner wall of the strip hole disappears, the thrust of the extrusion spring can drive the sealing plug plate frame to reset and seal the connection between the connecting pipe and the water collecting box. When the water collecting box moves, a group of control mechanisms in which the plug block is not separated from the shrinkage slot block will cause the plug column to leave the inside of the limiting sliding hole strip, driving the control mechanism to move as a whole, so that the sealing plug plate frame can continue to seal the connection between the connecting pipe that is not connected to the water spray pipe and the water collecting box, thereby improving the automation performance of the device.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Four shrinkage groove blocks 504 are fixedly connected to a part of the wall near the limit ring 502, and a through hole is provided on the side of the shrinkage groove block 504 away from the extended water outlet cylinder 501. The upper, lower, left and right sides of the water collecting box 505 are fixedly connected with connecting pipes 506, and the connecting pipes 506 are communicated with the water collecting box 505.

When the extended water outlet cylinder 501 drives the water collecting box 505 to move to a suitable distance to perform secondary pressurization on the water inside, the connecting pipe 506 that needs to be used will be automatically opened to spray out the pressurized water, and the opening of the connecting pipe 506 of the blocking plate frame 402 will change with the size of the water flow;

[0044] The control mechanism 4 is arranged inside the socket 509, and the control mechanism 4 includes a plugging plate rack 402, which is plugged into the socket 509, and the end of the top of the plugging plate rack 402 away from the water collecting box 505 is rotatably connected to the control pull bar 403, and the side of the plugging plate rack 402 away from the water collecting box 505 is fixedly connected to the sliding rack 401, and the end of the sliding rack 401 away from the plugging plate rack 402 is slidably connected to the inside of the shrinkage groove block 504, and the sliding rack 401 is connected to the limit ring 502. There are two extrusion springs 409 fixedly connected between them, a plug block 406 is inserted on the side of the contraction slot block 504 away from the extended water cylinder 501, a control handle 408 is fixedly connected to the top of the plug block 406, a plug column 407 is fixedly connected to the top of the control handle 408, the plug column 407 is embedded in the limiting sliding hole strip 305, the plug column 407 is slidably connected to the limiting plug hole 306, and a sliding bar 404 is fixedly connected to the side of the plug block 406 close to the water outlet pipe connecting frame 203, and the left and right sides of the sliding bar 404 A strip hole 405 is provided through the device, and one end of the control pull bar 403 away from the plugging plate frame 402 is slidably connected to the inside of the strip hole 405. When multiple connecting pipes 506 are connected to the external water spray pipe, before the device is operated, the control handle 408 is used to manually control the plug column 407 to slide inside the limit sliding hole strip 305, so that the plug column 407 is inserted into the limit plug hole 306, and the sliding bar 404 is driven to rise, so that the plug block 406 leaves the contraction slot block 504. When the extended water outlet cylinder 501 is in the water outlet When the docking tube 301 slides inside, the control strip 403 will be pulled to slide inside the strip hole 405 through the blocking plate frame 402. When the control strip 403 abuts against one end of the strip hole 405 close to the limit sliding hole strip 305 inside the strip hole 405 and the water cylinder 501 is extended to drive the water collecting box 505 to move continuously, a pulling force will be generated on the blocking plate frame 402, so that the blocking plate frame 402 is pulled outward inside the socket 509, thereby opening the connection between a connecting pipe 506 connecting the water spray pipe and the water collecting box 505.

[0045] When in use, the side of the water inlet 202 away from the pump body 201 is connected to the connecting back plate 103, so that the polygonal connecting column at the output end of the motor 104 is connected to the polygonal groove on the water pumping device inside the water inlet 202, and the pump body 201 is fixed to the main body 1 and the connecting back plate 103 by bolts. The motor 104 drives the water pumping device inside the water inlet 202 and the boosting device inside the pump body 201 to operate. After water is pumped into the pump body 201 for boosting, it is sprayed into the water outlet butt joint 301 through the water outlet pipe connecting frame 203, so that the boosted water enters the extended water outlet cylinder 501 and the water collecting box 505, and the boosted water flows continuously in the water outlet butt joint 301 and the extended water outlet cylinder 501. Water accumulates inside the water outlet tube 501. When the pressure inside the water outlet connecting tube 301 and the extended water outlet tube 501 is greater than the elastic force of the booster spring 508 as a whole, the extended water outlet tube 501 will be driven to slide inside the limiting slide 302 on the inner wall of the water outlet connecting tube 301, causing the water outlet connecting tube 301 to extend outward, while driving the sliding limiting connecting ring 503 to pass through multiple sliding holes 304 and slide on the outer wall of the water outlet connecting tube 301, and causing the booster spring 508 to stretch. When the pumping speed of the stabilizing slide bar 102 and the water pumping device inside the water inlet 202 is too slow, the water can be pressurized through the pump body 201 and enter the water outlet connecting tube 301 and the extended water outlet tube 501, and then a secondary pressurization can be performed before the water is discharged.

[0046] Example 2, please refer to Figure 1-Figure 9 As shown, when in use, when multiple connecting pipes 506 are connected to the external water spray pipe, before the device is operated, the plug column 407 is manually controlled by the control handle 408 to slide inside the limiting sliding hole strip 305, so that the plug column 407 is inserted into the limiting plug hole 306, and the sliding bar 404 is driven to rise, so that the plug block 406 leaves the contraction groove block 504, and when the extended water outlet cylinder 501 slides inside the water outlet docking pipe 301, the control pull bar 403 is pulled through the blocking plug plate rack 402 to slide inside the strip hole 405, and when the control pull bar 403 is against one end of the strip hole 405 close to the limiting sliding hole strip 305 and the extended water outlet cylinder 501 drives the water collecting box 505 to move continuously, the blocking plug plate rack 40 2 generates a pulling force, so that the plugging plate frame 402 is pulled outward inside the socket 509, thereby opening a connection pipe 506 connecting the water spray pipe and the water collecting box 505. This can not only prevent the water from being sprayed out through the connection pipe 506 and the water collecting box 505 due to the pressure when the extended water outlet cylinder 501 and the water outlet butt pipe 301 are continuously pressurized, but also enable the device to connect multiple water spray pipes at the same time. When the extended water outlet cylinder 501 drives the water collecting box 505 to move to a suitable distance to perform secondary pressurization on the water inside, the connection pipe 506 to be used will be automatically opened to spray the pressurized water, and the opening of the plugging plate frame 402 to the connection pipe 506 will change with the size of the water flow;

[0047] When the sealing plug plate rack 402 slides outward inside the insertion hole 509, it will drive the sliding rack 401 to slide inside the contraction slot block 504 and squeeze the extrusion spring 409, so that after the force between the control pull strip 403 and the inner wall of the strip hole 405 disappears, the thrust of the extrusion spring 409 can drive the sealing plug plate rack 402 to reset and seal the connection between the connecting pipe 506 and the water collecting box 505. When the plug block 406 is not separated from the contraction slot block 504, a group of control mechanisms 4 in which the plug block 406 is not separated from the contraction slot block 504 will cause the plug column 407 to leave the inside of the limiting sliding hole strip 305 when the water collecting box 505 moves, driving the control mechanism 4 to move as a whole, so that the sealing plug plate rack 402 can continue to seal the connection between the connecting pipe 506 that is not connected to the water spray pipe and the water collecting box 505, thereby improving the automation performance of the device.

[0048] A method for using a multi-stage booster pump comprises the following steps:

[0049] S1: The motor 104 drives the pumping device inside the water inlet 202 and the boosting device inside the pump body 201 to operate, pumping water into the pump body 201 for boosting, and then spraying water into the water outlet butt joint 301 through the outlet pipe connecting frame 203;

[0050] S2: The pressurized water enters the extended water outlet tube 501 and the water collecting box 505, and the pressurized water flow continues to accumulate in the water outlet butt joint tube 301 and the extended water outlet tube 501. When the pressure inside the water outlet butt joint tube 301 and the extended water outlet tube 501 is greater than the elastic force of the pressurizing spring 508, the extended water outlet tube 501 will be driven to slide inside the limiting slideway 302 on the inner wall of the water outlet butt joint tube 301, so that the water outlet butt joint tube 301 extends outward;

[0051] S3: At the same time, the sliding limit connecting ring 503 is driven to pass through the multiple sliding holes 304 to slide on the outer wall of the water outlet butt joint 301, and the pressure-increasing spring 508 is stretched. When the pumping speed of the stabilizing slide bar 102 and the water pumping device inside the water inlet 202 is too low, the water is pressurized by the pump body 201 and enters the water outlet butt joint 301 and the extended water outlet cylinder 501, and is pressurized twice before the water is discharged;

[0052] S4: When the extended water cylinder 501 drives the water collecting box 505 to move to a suitable distance, the connecting pipe 506 to be used will be automatically opened to spray out the pressurized water.
