In the present embodiment, the first pump body 5 has a high-pressure cavity 17 in the inner space thereof by the first piston 8; and the second pump body 6 is provided with an auxiliary cavity 18 through the second piston 9 in the inner space of the second pump body 6. The first water inlet 1 is communicated with the water outlet interface 11 through a reverse osmosis water inlet pipe 19, and the first water outlet 2 is communicated with the high-pressure water inlet interface 13 through a reverse osmosis wastewater pipe 20; the second water outlet 3 is communicated with the low-pressure water inlet interface 10 through an ultrafiltration water outlet pipe 21.

During specific use, the pedal 7 drives the first piston 8 and the second piston 9 to move, so that the water pressurization in the high-pressure cavity 17 is powered, and meanwhile, the auxiliary cavity 18 is powered, and the water pressure is recycled. The ultrafiltration water outlet pipe 21 is used for conveying low-pressure water from the reverse osmosis assembly 200 to the first pump body 5; the reverse osmosis water inlet pipe 19 is used for conveying the pressurized high-pressure water from the first pump body 5 to the reverse osmosis component 200; the reverse osmosis wastewater pipe 20 is used for conveying high-pressure wastewater generated by the reverse osmosis component 200 to the auxiliary cavity 18, at the moment, the wastewater enters the high-pressure cavity 17 through the relative movement of the second piston 9, and the wastewater is pressurized again, so that partial recovery of water pressure can be realized, the pressure required by driving the first piston 8 to pressurize the high-pressure cavity 17 is reduced, and the purpose of artificially inputting high-pressure water to the reverse osmosis component 200 under the condition of no electricity is achieved; by means of the relative movement of the second piston 9, the waste water which has undergone pressure recovery can be discharged from the high-pressure pump 100 via the waste water connection 12.

For a better use of this embodiment, a first spring 22 is provided between the compression end of the first piston 8 and the first cylinder 5 for the return of the first piston 8.

For better use of this embodiment, a second spring 23 is provided between the compression end of the second piston 9 and the second cylinder 6 for resetting the second piston 9; said second spring 23 is located inside the second pump body 6.

In the present embodiment, the first pump body 5 has a first end cap 24, and the second pump body 6 has a second end cap 25; the first end cap 24 and the second end cap 25 can well realize the internal sealing of the corresponding pump body.

Specifically, the first spring 22, the first piston 8 and the first end cover 24 are sequentially arranged in the first pump body 5 from top to bottom; the second piston 9, the second spring 23 and the second end cover 25 are sequentially arranged in the second pump body 6 from top to bottom.

The low pressure water inlet port 10 has a first check valve 15, which can control water to be input into the first pump body 5 only from the ultrafiltration water outlet pipe 21, and it should be noted that, in the first pump body 5, the first piston 8 divides the first pump body 5 into a high pressure cavity 17 and a water inlet cavity 26, and the water inlet cavity 26 is where the first spring 22 is located, so that the low pressure water inlet port 10 is used for controlling water to be input into the water inlet cavity 26 only from the ultrafiltration water outlet pipe 21. The water outlet port 11 is provided with a second one-way valve 16, so that water can be controlled to be input only from the ultrafiltration water outlet pipe 21, in the process, the first spring 22 drives the first piston 8 to move towards the direction far away from the first one-way valve 15, the first one-way valve 15 is opened, the second one-way valve 16 is closed, water in the ultrafiltration water outlet pipe 21 enters the water inlet cavity 26 for pressurization, the pedal plate 7 drives the first piston 8 to move towards the direction close to the first one-way valve 15, at the moment, the first one-way valve 15 is closed, the second one-way valve 16 is opened, and the pressurized water can be input into the reverse osmosis component 200 through the reverse osmosis water inlet pipe 19, so that water conveying work is completed.

It should be noted that the second chamber is divided into two chambers, namely an upper chamber 27 and a lower chamber 28, by the second piston 9, and the auxiliary chamber 18 includes the upper chamber 27 and the lower chamber 28, thereby performing the actual pressurization. In a specific use process, the middle part of the second pump body 6 is provided with a wastewater interface 12 which is communicated with the upper cavity 27, and the second piston 9 is driven to move towards a direction far away from the wastewater interface 12 through the movement of the pedal 7, so that the lower cavity 28 is respectively communicated with the high-pressure water inlet interface 13 and the high-pressure cavity 17, and thus high-pressure wastewater output from the reverse osmosis assembly 200 can enter the high-pressure cavity 17 through the first water outlet 2; at this time, the second piston 9 pressurizes the wastewater to complete the pressure part recovery of the wastewater, the second piston 9 is driven by the second spring 23 to move towards the direction close to the wastewater interface 12, so that the upper cavity 27 is communicated with the high-pressure cavity 17, and at this time, the lower cavity 28 cannot be communicated with the high-pressure cavity 17, so that the pressure maintaining of the split permeation assembly is realized, the pressure conversion is completed, the wastewater is pressurized, and the wastewater is discharged from the wastewater interface 12.

For better use of the present embodiment, the first pump body 5 and the second pump body 6 are arranged side by side, and a first through hole 29 is provided between the first pump body 5 and the second pump body 6; the first through hole 29 is close to the driving end of the second piston 9 relative to the high-pressure water inlet port 13.

When the second piston 9 moves, the upper cavity 27 is communicated with the high-pressure cavity 17 through the first through hole 29 by changing the positions of the upper cavity 27 and the lower cavity 28, or the lower cavity 28 is communicated with the high-pressure cavity 17 through the first through hole 29, in the specific high-pressure pump 100, the position of the first through hole 29 is closer to the second spring 23 relative to the high-pressure water inlet port 13, so that the state when the upper cavity 27 or the lower cavity 28 is communicated with the high-pressure cavity 17 through the first through hole 29 is more stable, and liquid leakage is avoided.

For better use of this embodiment, the first piston 8 is of T-shaped configuration.

Since the first piston 8 is of T-shaped configuration, it is mainly composed of two parts, a first part 30 and a second part 31; the first portion 30 and the second portion 31 are arranged vertically and the diameter of the second portion 31 is greater than the diameter of the first portion 30, thereby realising that the first portion 30 and the first pump body 5 form a high pressure cavity 17.

For better use of the present embodiment, the second piston 9 has a first ring groove 32 and a second ring groove 33; the first ring groove 32 is located in the middle of the second piston 9, and the second ring groove 33 is located at one end of the second piston 9 far from the driving end; the second piston 9 is provided with a second through hole 34, one end of the second through hole 34 is arranged in the first ring groove 32, and the other end is arranged at the end far away from the driving end of the second piston 9.

Due to the arrangement of the first ring groove 32 and the second ring groove 33, the upper cavity 27 is formed between the first ring groove 32 and the second pump body 6, and the lower cavity 28 is formed between the second ring groove 33 and the second pump body 6, so that the positions of the upper cavity 27 and the lower cavity 28 are changed along with the continuous movement of the second piston 9, and the pressure conversion is completed. The second through hole 34 is arranged to well communicate the upper cavity 27 with the waste water interface 12 under a certain state, so as to meet the requirement of waste water discharge.

For better use of this embodiment, the driving end of the first piston 8 is provided with a first pin 35; the outer frame support 4 is provided with a slide hole 36 which is engaged with the first pin 35.

Two sides of the outer frame support 4 are respectively provided with a waist-shaped hole, and two ends of the first pin rod 35 respectively slide in the corresponding waist-shaped holes, so that the requirement that the pedal 7 drives the first piston 8 is met. In fact, the driving end of the second piston 9 is provided with a second pin 37, and both ends of the second pin 37 are rotatably connected to the corresponding side of the pedal 7, so that the pedal 7 is operated and the second piston 9 can be driven. Specifically, when the pedal 7 moves, the first pin rod 35 and the second pin rod 37 respectively drive the first piston 8 and the second piston 9 to move in one direction; when both the first spring 22 and the second spring 23 are compressed to the limit, the pedal 7 is released, and the return movement of the first piston 8 and the second piston 9 is effected by the first spring 22 and the second spring 23, respectively, thereby effecting the one-way movement of the first piston 8 and the second piston 9 in the other direction, in the opposite direction to the one-way movement described above, thereby effecting the return of the first piston 8 and the second piston 9.

In the use of the present embodiment, since the first piston 8 has a fulcrum on the outer frame support 4 and the second piston 9 and the outer frame support 4 have no relation of connection with each other, the second piston 9 always moves prior to the first piston 8 when the foot board 7 moves.

When the pedal 7 is manually stepped on, the first pin rod 35 and the second pin rod 37 respectively drive the first piston 8 and the second piston 9 to move, when the first piston 8 moves towards the direction close to the first check valve 15, the pressure in the water inlet cavity 26 is increased at the moment, the second check valve 16 is opened, the first check valve 15 is closed, water in the water inlet cavity 26 cannot flow back to the ultrafiltration assembly 300 through the ultrafiltration water outlet pipe 21 at the moment, and only can enter the reverse osmosis assembly 200 through the second check valve 16 and the reverse osmosis water inlet pipe 19 in a one-way mode, at the moment, the second piston 9 is located at the highest point, the lower cavity 28 in the second piston 9 is respectively communicated with the high-pressure cavity 17 and the high-pressure water inlet interface 13, and wastewater in the reverse osmosis assembly 200 can enter the high-pressure cavity 17 through the reverse osmosis wastewater pipe 20, the high-pressure water inlet interface 13 and the lower cavity 28, so that the wastewater pressurization is realized.

When the first spring 22 and the second spring 23 drive the first piston 8 and the second piston 9 to move respectively, the first piston 8 moves away from the first one-way valve 15, so that the pressure of the water inlet cavity 26 becomes low, the first one-way valve 15 is opened, water in the ultrafiltration module 300 enters the water inlet cavity 26 only through the ultrafiltration water outlet pipe 21 and the first one-way valve 15, at the moment, the second piston 9 is located at the lowest point, at the moment, the upper cavity 27 is communicated with the high-pressure cavity 17 through the first through hole 29, and therefore, the water can be communicated with the wastewater interface 12 through the second through hole 34, so that wastewater is discharged; at this time, the wastewater in the reverse osmosis module 200 is communicated only with the lower cavity 28 through the reverse osmosis wastewater pipe 20 and the high-pressure water inlet port 13, and thus cannot be discharged, and the pressure is maintained in the reverse osmosis module 200.

Since the first spring 22 and the second spring 23 are provided in the present embodiment, after the foot board 7 is released, the first spring 22 and the second spring 23 can perform rebound to return the foot board 7, thereby completing a cycle.

It should be noted that, under the action of the foot pedal 7, the water in the ultrafiltration water outlet pipe 21 enters the water inlet cavity 26 through the first check valve 15, after the water is pressurized by the first piston 8, the water enters the reverse osmosis module 200 through the second check valve 16 and the reverse osmosis water inlet pipe 19, and then the obtained wastewater enters the high pressure cavity 17 through the high pressure water inlet port 13 and the upper cavity 27 to be subjected to auxiliary pressurization, and finally the wastewater is discharged from the wastewater port 12. In the process, water/waste water flows in a single direction, backflow does not occur, and during pressure relief, the reverse osmosis component 200 and the waste water interface 12 are isolated from each other to achieve the purpose of pressure maintaining, so that the purpose of pressurizing and conveying water is achieved by replacing an electric pump, cooperative work between the ultrafiltration component 300 and the reverse osmosis component 200 is achieved, under the condition of no electricity, the requirement of water production is met, and therefore small-sized artificial water treatment is achieved.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
