[0024] As shown in the figure, the end of movable pipe 2 is designed as flared, which is in close contact with the inner wall of fixed pipe 21, and rubber ring is fixedly installed on the outer side of the end of movable pipe 2 in close contact with the inner wall of fixed pipe 21. Figure 3 Specifically, the flared design can make the water flow more easily from the inside of fixed pipe 21 to the inside of movable pipe 2, reducing water flow resistance.

[0025] As shown in the figure, a plurality of first anti-skid ring grooves 3 are formed on the outer side of the end of fixed pipe 21 away from movable pipe 2, and a plurality of second anti-skid ring grooves 31 are formed on the outer side of the end of water outlet pipe 12 away from movable pipe 2.

Figure 3 As shown in the figure, when movable ring 212 is in close contact with limiting ring 215, spring 214 is in a compressed state.

[0029]

[0030] Figure 3 As shown in the figure, when movable ring 212 is in close contact with limiting ring 215, spring 214 is in a compressed state.

[0031] ​​​Specifically: the spring 214 can provide initial elastic force to prevent the movable pipe 2 from shaking under the influence of water flow, so that the movable pipe 2 provides buffering only when it is impacted by water flow of a certain intensity, which can effectively prevent the water inlet end connection of the pressure boosting power saving device from falling off due to water flow impact and improve the stability of use.

[0032] Principle of use: when in use, the water inlet pipe 11 of the pressure boosting device body 1 is composed of the movable pipe 2 and the fixed pipe 21 that can slide relative to each other, the outer side end of the fixed pipe 21 is sleeved with the second application pipe 112 that is communicated with the water pump, the outer side of the water outlet pipe 12 of the pressure boosting device body 1 is sleeved with the first application pipe 111 that is communicated with the water delivery end, when the water flow with constant flow rate flows through the pressure boosting device body 1, the cross-sectional area of the water flow is reduced, and then the water outlet pressure is increased, so that the water flow can be delivered to a farther distance; when the water flow flows into the pressure boosting device body 1, the relatively narrow outlet end inner wall generates resistance to the water flow, and then the water flow impact acts on the outlet end inner wall of the entire pressure boosting device body 1, so that the entire pressure boosting device body 1 is subjected to the impact force in the direction of the water flow, however, the connection between the pressure boosting device body 1 and the second application pipe 112 is fixedly connected, and then the impact force makes the movable pipe 2 move and the movable ring 212 press the spring 214, and the buffering of the spring 214 can effectively reduce the loosening of the connection due to the water flow force; when the movable ring 212 and the fixed ring 211 are fixedly installed with the buffer rubber pad 4 on the opposite sides, the impact resistance of the movable pipe 2 can be further improved, and the use effect is good.
