[0002] Water purification equipment refers to the equipment for producing purified water. Most of them use reverse osmosis process. Reverse osmosis is a physical method without phase change that desalts and removes salt from salt water at room temperature. It includes a miniature water purification device that is directly installed and suspended on a household faucet. The faucet water purifier has the effect of improving water quality immediately, and its installation and maintenance procedure is simple and convenient, and can filter bleaching powder and chlorine ammonia and other disinfectants in water, thereby realizing the function of purifying water.

[0003] Although the filter membrane in the current water purifier can play a filtering effect, with the increase of use time, the filter membrane will be gradually blocked due to the accumulation of sundries. When the water supply pressure is small, the filter membrane can be cleaned by periodically disassembling the equipment, but when the water supply pressure is large, the pressure in the filter bottle will increase. If the filter membrane is blocked, the water pressure cannot be released, and once it exceeds a certain value, the filter bottle will burst, which is a problem. Therefore, we propose a water-saving pressure reducing system for water purification water supply equipment to improve. UTILITY MODEL CONTENT

[0026] Reference Figures 1-4 The water-saving pressure reducing system of the water purification and supply equipment provided by the utility model comprises a buffer joint 1 and a filter bottle 15, the lower end of the filter bottle 15 is threadedly connected with a water guide head 14, the lower end of the water guide head 14 is fixedly sleeved with a honeycomb water outlet head 18, one side of the water guide head 14 is fixedly sleeved with a dismounting head 3, the dismounting head 3 is threadedly connected on the buffer joint 1, a fixed shaft 5 is rotatably connected in the buffer joint 1, the outer wall of the fixed shaft 5 is fixedly sleeved with a water guide blade 6 and a friction roller 13 respectively, the outer wall of the buffer joint 1 is fixedly connected with a mounting frame 7, and the friction roller 13 is rotatably arranged in the mounting frame 7.

[0027] The mounting head 2 is fixedly connected to the buffer joint 1 on the side away from the dismounting head 3, the buffer joint 1 is fixedly sleeved with the primary filter screen 4 on the side close to the dismounting head 3, the water guide blade 6 is rotationally arranged in the buffer joint 1, and the front and back surfaces of the water guide blade 6 are slidingly attached to the inner wall of the buffer joint 1, the water flows to the upper part of the buffer joint 1 through the mounting head 2, the water guide blade 6 starts to rotate under the driving of the water flow, the water guide blade 6 forms a buffer, and the water pressure is reduced.

[0028] The spring 12 is fixedly connected between the inner walls of the two guide columns 10 and the two clamping cylinders 11, the contact ends of the two clamping cylinders 11 and the friction roller 13 are made of arc-shaped gaskets, and the bending radii of the arc-shaped gaskets are the same as the radius of the friction roller 13. The two sliding blocks 9 are symmetrically arranged about the center of the bidirectional screw rod 8, and one end of the bidirectional screw rod 8 penetrates through the mounting frame 7 and is fixedly sleeved with a knob. The bidirectional screw rod 8 is driven to rotate by the knob, and then the relative movement of the two sliding blocks 9 can be controlled, so that the contact pressure of the clamping cylinder 11 on the friction roller 13 is finally adjusted, and the rotational resistance of the friction roller 13 is adjusted.

[0029] The ultrafiltration membrane 16 is fixedly sleeved in the filter bottle 15, the water guide pipe 17 is fixedly sleeved in the water guide head 14, and the center of the water guide head 14 and the center of the water guide pipe 17 are located on the same vertical line.

[0030] Working principle:

[0031] In use, the mounting head 2 is threadedly connected to the water supply pipe, then the water flow enters the buffer joint 1, and the water guide blade 6 is driven to rotate under the driving of the water flow, then the water flow passes through the primary filter screen 4 to filter large particles, enters the water guide head 14, and then flows out of the filter bottle 15 from the outside of the water guide pipe 17, and then flows out of the honeycomb water outlet head 18. In this process, the rotation of the water guide blade 6 will drive the fixed shaft 5 to rotate, and then drive the friction roller 13 to rotate, because the friction roller 13 is attached to the arc-shaped gasket of the clamping cylinder 11, the rotation of the friction roller 13 will have a certain resistance, so that the rotation of the water guide blade 6 has a certain resistance, so as to reduce the water pressure entering the filter bottle 15, and in the use process, when the clamping cylinder 11 and the friction roller 13 are worn, the compressed spring 12 will compensate the pressure, so as to avoid the increase of the water pressure, in addition, in actual use, if it is found that the water pressure is still large, the two sliding blocks 9 can be relatively moved by rotating the bidirectional screw rod 8, so as to further compress the spring 12 through the guide column 10, so as to increase the pressure of the clamping cylinder 11 on the friction roller 13, and then increase the rotational resistance of the water guide blade 6.
