Description

Technical Field

[0001] The utility model belongs to the technical field of electric water boilers, and in particular relates to a reverse osmosis filtering and purifying device for purifying electric water boilers. Background Art

[0002] The electric water boiler consists of an electric heating tube, a controller, a solenoid valve, a check valve, a filter and a liquid level meter.

[0003] In the Chinese utility model patent with patent number CN202023014859.8 and the name of a reverse osmosis filtration purification device for purifying an electric water boiler, tap water is introduced into the interior of the filter tank through an inlet pipe. The tap water entering the filter tank will pass through multiple filter screens with different mesh sizes to filter out particulate impurities of different sizes in the tap water and retain them on the top of the filter screen. Moreover, the filter screen has many holes and will not be blocked. When cleaning is needed, the filter tank is removed from the fixed frame, the filter tank is opened and the sleeve is pulled out upward, which is convenient for cleaning and maintenance of the filter screen, and can also prevent particulate matter in the tap water from reducing the working efficiency of the RO filter tank. However, since the existing filter tank is placed vertically, particulate impurities will cover the filter screen. Although the particulate impurities cannot cause blockage to the filter screen, they will affect the speed of water flowing through the filter screen, and the filter screen needs to be disassembled and cleaned many times. Excessive disassembly and assembly of the filter screen will affect its own purification effect, and too many disassembly and assembly of the filter screen will increase the later maintenance cost of the equipment.

[0024] As described above, when using the electric water boiler body 1, water inlet pipe 5, filter tank 10, connecting pipe 8, water tank 7 and filter assembly provided by the utility model, the filter tank 10 is connected with the water tank 7 through the connecting pipe 8, and the external tap water is conveniently introduced into the filter tank 10 through the water inlet pipe 5. After the tap water enters the filter tank 10, the passing tap water is graded and filtered through multiple filter assemblies. The filtered tap water enters the water tank 7 for heating and storage. After the impurities in the tap water are blocked by the filter assembly, they are automatically gathered at the bottom of the filter tank 10 under gravity, so as to avoid the impurities clogging the filter assembly and improve the passability of the filter assembly.

[0025] In the present utility model, combined with Figure 2As shown, a collecting mechanism for collecting impurities is provided at the bottom of the filter tank 10 of this embodiment, one end of the collecting mechanism extends to the outside of the electric water boiler body 1, and the collecting mechanism is connected to the bottom of multiple filter spaces.

[0026] Combination Figure 2 As shown, the collecting mechanism includes a plurality of dirt storage hoppers 9, which are all installed at the bottom of the filter tank 10, and the plurality of dirt storage hoppers 9 are respectively connected to the corresponding filter spaces. A valve 4 is provided on the outside of the electric water boiler body 1, and a sewage pipe 3 is provided between the valve 4 and the bottom of the plurality of dirt storage hoppers 9.

[0027] As described above, when using the collecting mechanism provided by the utility model, the dirt storage hopper 9 in the collecting mechanism collects impurities at the bottom of the filter space. When it is necessary to discharge the impurities in the filter space, the valve 4 on the sewage pipe 3 is opened, and the impurities in the dirt storage hopper 9 are driven to be discharged outward through the sewage pipe 3 under water pressure. After a period of time, the valve 4 is closed to complete the discharge of impurities.

[0028] Further, in order to facilitate the connection of the sewage pipe 3 with the external sewer, refer to Figure 1-2 As shown, an extension pipe 2 is also installed at one end of the sewage pipe 3 away from the dirt storage hopper 9, and at least part of the extension pipe 2 is a hose. The sewage pipe 3 can be connected to the sewer pipe through the extension pipe 2, so that impurities are directly discharged into the sewer pipe.

[0029] In the present utility model, combined with Figure 4-5 As shown, the filter assembly of this embodiment includes a piston 12, a mounting ring seat 18 and a filter screen 19 which are arranged in sequence from the outside to the inside. The filter screen 19 is embedded in the inner wall of the mounting ring seat 18. An internal thread groove 16 is opened on the inner wall of the piston 12. The mounting ring seat 18 is screwed into the internal thread groove 16. Two grooves 17 are also symmetrically installed on one side of the mounting ring seat 18.

One end of the cap 6 is threadedly connected to extend into the filter tank 10. A mounting frame 11 for connecting multiple pistons 12 is also provided on the inside of the cap 6.

[0031] As mentioned above, when using the filter assembly provided by the utility model, the end of the filter tank 10 can be sealed and opened by the cap 6, which is convenient for installing the filter assembly in the filter tank 10 or taking it out of the filter tank 10. The special tool is inserted into the two grooves 17, and the special tool is rotated to drive the mounting ring seat 18 to screw into the internal thread groove 16 on the piston 12, so that the mounting ring seat 18 can be detachably installed on the piston 12. The mounting ring seat 18 provides an installation position for the filter screen 19, thereby facilitating the replacement of the filter screen 19.

[0032] Further, in order to facilitate the removal of the plurality of pistons 12 from the filter tank 10, refer to Figure 2 As shown, the mounting frame 11 is a U-shaped structure, and both ends of the mounting frame 11 are respectively installed on multiple pistons 12. The mounting frame 11 is convenient for fixing multiple pistons 12 together, and the mounting frame 11 is convenient for driving multiple pistons 12 into the filter tank 10 or taking them out of the filter tank 10.

The mounting frame 11 is fixedly mounted on the rotating member 14 by the fastening bolt 15, so that the piston 12 is detachably mounted on the cap 6. When the cap 6 is screwed on the filter tank 10, the piston 12 cannot be displaced in the filter tank 10 through the mounting frame 11 and the rotating member 14. At the same time, the rotating groove 13 allows the mounting frame 11 and the plurality of pistons 12 to avoid interfering with the installation of the cap 6.
