[0004] The number of micro-wastewater water-saving modules in the existing water purifiers such as the above can be increased or decreased according to the usage requirements. The micro-wastewater water-saving module is mostly composed of several parts such as an RO micro-wastewater membrane, a one-way valve, a six-chamber booster pump, a reflux ratio valve, a raw water solenoid valve, a wastewater solenoid valve and an energy storage core. In the specific implementation process, the components in the micro-wastewater water-saving module are dispersedly arranged, that is, each component needs to be independently assembled with the inner surface wall of the water purifier housing, which makes the process of increasing or decreasing the micro-wastewater water-saving quantity more inconvenient later. Therefore, it is urgent to propose a corresponding micro-wastewater water-saving module for a water vending machine to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0025] Automatic water dispenser micro-wastewater water-saving module, including a bottom frame 2 and a micro-wastewater water-saving unit. The micro-wastewater water-saving unit includes an RO micro-wastewater membrane 3, a one-way valve 4, a six-chamber booster pump 5, a reflux ratio valve 6, a raw water solenoid valve 7, a wastewater solenoid valve 8, and an energy storage and energy-saving core 9. The bottom frame 2 is detachably connected to the inner wall of the automatic water dispenser. The RO micro-wastewater membrane 3, the one-way valve 4, the six-chamber booster pump 5, the reflux ratio valve 6, the raw water solenoid valve 7, the wastewater solenoid valve 8, and the energy storage and energy-saving core 9 are all fixedly installed on the front end face of the bottom frame 2, and the front end face of the bottom frame 2 is fixedly connected to a front frame 13 through an extension rod 12;

[0026] After installing the RO micro-wastewater membrane 3, the one-way valve 4, the six-chamber booster pump 5, the reflux ratio valve 6, the raw water solenoid valve 7, the wastewater solenoid valve 8, and the energy storage and energy-saving core 9 to the designated positions on the bottom frame, after disassembling the housing of the automatic water dispenser subsequently, the assembled bottom frame 2 can be integrally fixed to the designated position of the housing through the cooperation of the installation rod 11 and the tab 10. Then, the extension rod 12 is fixed to the front side of the bottom frame 2. At this time, the front frame 13 can be erected on the front side of each component, ensuring the convenience of disassembly and assembly of the automatic water dispenser micro-wastewater water-saving module, and at the same time, protecting each component through the front frame 13.

[0027] Specifically, as Figure 2 shown in Figure 4 , a hanger 14 is fixedly connected to the front end face of the front frame 13. A cross bar 17 is slidably connected between the hanger 14 and the front frame 13, and a positioning part for positioning the cross bar 17 is provided between the hanger 14 and the cross bar 17. The positioning part includes a positioning rod 16. The positioning rod 16 is screwed to the inner wall of the hanger 14 through a screw hole 15, and the positioning rod 16 is inserted into the cross bar 17 through a perforation. Multiple groups of screw holes 15 are provided, and multiple groups of screw holes 15 are linearly distributed vertically. Both sides of the vertical end of the hanger 14 are open. Push the cross bar 17 to slide between the hanger 14 and the front frame 13 until the cross bar 17 moves to a suitable position. Rotate the positioning rod 16 to engage the screw hole 15 at the corresponding position while inserting it into the perforation inside the cross bar 17 to fix the cross bar 17 to the front frame 13. At this time, the corresponding pipes and wire harnesses can be tightened on the cross bar 17 through external cable ties to prevent the pipes and wire harnesses of each component from hanging or loosening, thereby improving the stability of the use of the automatic water dispenser micro-wastewater water-saving module. And since both sides of the vertical part of the hanger 14 are open, the number of cross bars 17 can be increased or decreased according to the use requirements.

[0028] Specifically, as Figure 2 shown in Figure 3 , the automatic water dispenser includes an automatic water dispenser housing 1. Both sides of the vertical end of the bottom frame 2 are fixedly connected with tabs 10. The two groups of tabs 10 are respectively screwed to the inner wall of the automatic water dispenser housing 1 through two groups of installation rods 11;

[0029] After installing the RO micro-wastewater membrane 3, one-way valve 4, six-chamber booster pump 5, reflux ratio valve 6, raw water solenoid valve 7, wastewater solenoid valve 8 and energy storage core 9 at the designated positions on the bottom frame, after subsequently disassembling the housing of the automatic water dispenser, the assembled bottom frame 2 can be integrally fixed to the designated position on the housing through the cooperation of the mounting rod 11 and the lug 10. The extension rod 12 is in an L-shaped structure, and the horizontal end of the extension rod 12 is fixedly connected to the bottom frame 2 through a fastening rod, so as to ensure the convenience of disassembling and assembling the front frame 13 and the bottom frame 2;

[0030] It should be noted that: the automatic water dispenser housing 1 here is a broad concept. When applied to large water dispensers in some communities, on the premise that screw holes are preset inside the large water dispenser, this micro-wastewater water-saving module can still be quickly installed through the cooperation of the lug 10 and the mounting rod 11.

[0031] Working principle: After installing the RO micro-wastewater membrane 3, one-way valve 4, six-chamber booster pump 5, reflux ratio valve 6, raw water solenoid valve 7, wastewater solenoid valve 8 and energy storage core 9 at the designated positions on the bottom frame, after subsequently disassembling the housing of the automatic water dispenser, the assembled bottom frame 2 can be integrally fixed to the designated position on the housing through the cooperation of the mounting rod 11 and the lug 10. Then fix the extension rod 12 to the front side of the bottom frame 2. At this time, the front frame 13 can be erected on the front side of each component, which not only ensures the convenience of disassembling and assembling the micro-wastewater water-saving module of the automatic water dispenser, but also protects each component through the front frame 13. Push the cross bar 17 to slide it between the scaffold 14 and the front frame 13 until the cross bar 17 moves to a suitable position. Rotate the positioning rod 16 to engage the corresponding screw hole 15 while inserting it into the through hole inside the cross bar 17 to realize the fixation of the cross bar 17 and the front frame 13. At this time, the corresponding pipes and wire harnesses can be tied tightly to the cross bar 17 through external cable ties to prevent the pipes and wire harnesses of each component from hanging or loosening, thereby improving the stability of the use of the micro-wastewater water-saving module of the automatic water dispenser. And because both vertical sides of the scaffold 14 are open, the number of cross bars 17 can be increased or decreased according to the usage requirements.

[0032] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
