DETAILED DESCRIPTION

[0024] The embodiment of the present invention provides a multi-stage drinking water purification and disinfection device, such as Figures 1-4 As shown, it includes a riser 1 and several disinfection components. The front and rear ends of the riser 1 are connected to the water inlet pipe and the water outlet pipe. The riser 1 serves as a purification and disinfection device. In this embodiment, three groups of disinfection components are used. Several notches 2 are opened on the riser 1. The circumferential angle of the notch 2 is about 240°, and there is no interference when the fixed cylinder 3 enters.

[0025] Each disinfection assembly utilizes a different sterilizer 4. For example, the first-stage sterilizer utilizes an immersion UV sterilizer lamp, which passes through the water within the first-stage fixed cylinder 3 to achieve primary disinfection. The second-stage sterilizer utilizes an ozone generator, activated by a solenoid valve to achieve secondary disinfection. The third-stage sterilizer utilizes a flow-through UV sterilizer lamp, which is located within the third-stage fixed cylinder 3 to achieve tertiary disinfection. This three-stage disinfection system ensures effective disinfection and sterilization.

[0026] like Figure 1 As shown, the disinfection assembly includes a plurality of circular fixed cylinders 3, a disinfector 4 and a bracket 5. The disinfector 4 is fixed in the central through groove of the fixed cylinder 3 by means of bolts or latches.

[0027] Several fixed cylinders 3 are circumferentially arranged at equal angles on a bracket 5. A sterilizer 4 is positioned at the center of the fixed cylinder 3. The distance from the center of the bracket 5 to the center of the sterilizer 4 is equal to the distance from the center of the bracket 5 to the center of the standpipe 1. The fixed cylinder 3 can enter the axis of the standpipe 1 through the notch 2. The multiple brackets 5 are controlled by a linkage mechanism 6. A fixing mechanism for securing the fixed cylinder 3 is provided within the standpipe 1.

[0028] like Figure 1 As shown, the linkage mechanism includes a support plate 61, a linkage shaft 62 and a motor 63. The support plate 61 is fixed to the ground through a mounting bracket. The centers of the several brackets 5 are coaxially rotated on the support plate 61 through the linkage shaft 62. The motor 63 is arranged at the bottom of the support plate 61 and is connected to the linkage shaft 62. The linkage shaft 62 is driven to rotate by the motor 63, thereby controlling the three-stage sterilizer 4 to achieve synchronous replacement. Compared with the traditional method of replacing the sterilizer by disassembling a single filter device, this device can achieve synchronous replacement of multiple-stage sterilizers without disassembling the riser, and the replacement efficiency is higher. The motor 63 is a stepper motor. When the number of the fixed cylinders 3 is four, the stepper motor drives the bracket 5 to rotate 90° each time.

[0029] like Figure 2 As shown, the fixing mechanism includes a cylindrical carrier 8, two sets of snap rings 11, and a spring 15. An annular slide groove 9 is provided at both the upper and lower ends of the carrier 8. The carrier 8 is located at the top of the slide groove 9 as a support ring 10. The two sets of snap rings 11 correspond to the upper and lower slide grooves 9, respectively. A limit ring 13 is provided on the top of the snap ring 11, which slides and fits in the slide groove 9. The upper and lower snap rings 11 are used to fix the fixed cylinder 3. The two ends of the spring 15 connect the limit ring 13 and the support ring 10. The upper and lower sides of the fixed cylinder 3 are provided with a slot 12 for the bottom end of the snap ring 11 to be inserted. Under the action of the spring 15, the distance between the ends of the two limit rings 13 is smaller than the distance between the upper and lower slots 12 of the fixed cylinder 3.

[0030] In order to be able to separate the clamping ring 11 from the clamping groove 12 when disassembling and replacing the fixing cylinder 3, an adsorption component is provided on the support ring 10 and the limiting ring 13.

[0031] like Figure 2-Figure 3 As shown, the adsorption component includes a plurality of magnetic blocks 16 and a plurality of electromagnets 17. The magnetic block 16 is arranged on the top of the limit ring 13, and the plurality of magnetic blocks 16 are distributed at equal angles around the center of the limit ring 13. The electromagnet 17 is arranged on the support ring 10 and corresponds to the magnetic blocks 16 one by one. When the electromagnet 17 is energized, the magnetic pole of the side corresponding to the magnetic block 16 is opposite.

[0032] When the electromagnet 17 adsorbs the magnetic block 16, the bottom end of the snap ring 11 completely disengages from the slot 12. At this time, the rotating fixed cylinder 3 can be moved out of the riser 1 from the notch 2.

[0033] The carrier 8 is provided with a limiting groove 14 at the bottom of the slide groove 9 , and the end of the limiting ring is provided with a bending portion that can be inserted into the limiting groove 14 .

[0034] To ensure a tight seal between the upper and lower ends of the snap ring 11 and the carrier 8 and the fixed cylinder 3, a ring of sealing tape is provided in both the retaining groove 14 and the retaining groove 12. Under the action of spring 15, the bottom end of the snap ring 11 presses against the sealing tape in the retaining groove 12, and the bent portion of the retaining ring 13 presses against the sealing tape in the retaining groove 14, thus achieving a seal at the upper and lower ends of the snap ring 11 and allowing water flowing down from above to flow along the snap ring 11 into the sterilizer 4.

[0035] In order to prevent the clamping ring 11 from floating up and down, a limiting component for limiting the vertical floating of the limiting ring 13 is also provided on the carrier 8.

[0036] like Figure 2-Figure 3 As shown, the limiting assembly includes a wedge block 18, a guide groove 19, a second spring 20, and a second electromagnet 21. The wedge block 18 has an inclined surface on one side corresponding to the support ring 10 and a flat surface on the other side. That is, when the bent section of the limiting ring 13 is inserted into the limiting groove 14, it first contacts the inclined surface of the wedge block 18. Then, after the bent section is fully inserted into the limiting groove 14, the top of the limiting ring 13 is located below the flat surface of the wedge block 18. The flat surface of the wedge block 18 restrains the limiting ring 13, preventing the retaining ring 11 from floating vertically. The guide groove 19 is horizontally defined on the carrier 8. The tail end of the wedge block 18 slides into the guide groove 19. The second electromagnet 21 is located at the end of the guide groove 19 and corresponds to the wedge block 18. The second spring 20 is located between the second electromagnet 21 and the wedge block 18. The tail end of the wedge block 18 is magnetic. When the second electromagnet 21 is energized, the magnetic pole is opposite to the surface corresponding to the wedge block 18. Under the action of spring 20, the inclined surface of wedge-shaped block 18 is completely exposed outside the guide groove 19. When electromagnet 21 is energized, wedge-shaped block 18 can be completely adsorbed and retracted into the guide groove 19.

[0037] like Figure 4 As shown, the device also includes a controller 7 for controlling electromagnet 17 and electromagnet 2 21. The controller 7 includes a shell 71, a sliding block 73, a trigger switch 1 74, and a trigger switch 2 75. A transverse slide 72 for sliding the sliding block 73 is opened transversely in the shell 71. The trigger switch 1 74 and the trigger switch 2 75 are arranged on the side wall of the transverse slide 72. The trigger switch 1 74 is electrically connected to the electromagnet 2 21. The trigger switch 1 74 is used to control the electromagnet 2 21. The trigger switch 2 75 is electrically connected to the electromagnet 1 17. The trigger switch 2 75 is used to control the electromagnet 1 17. The sliding block 73, the trigger switch 1 74, and the trigger switch 2 75 are arranged in sequence.

[0038] The controller 7 of the use state is as follows Figure 4As shown, when the sterilizer 4 needs to be replaced, the sliding block 73 is slid toward the trigger switch 1 74. The sliding block 73 first contacts the trigger switch 1 74, energizing the electromagnet 2 21 and attracting the wedge block 18 to retract into the guide groove 19. The sliding block 73 then contacts the trigger switch 2 75, energizing the electromagnet 1 17, attracting the magnetic block 16 and the snap ring 11. At this time, the snap ring 11 is separated from the fixed cylinder 3. The fixed cylinder 3 can be rotated 90° by the driving bracket 5. When the new fixed cylinder 3 and the sterilizer 4 enter the axis of the standpipe 1, the sliding block 73 is driven to move in the opposite direction. The sliding block 73 first disengages from the trigger switch 2 75, and the electromagnet 1 17 is first de-energized, causing the snap ring 11 to descend and snap into the snap groove 12. At this time, since the electromagnet 2 21 is not de-energized, the wedge block 18 will not hinder the downward movement of the snap ring 11. Then the sliding block 73 contacts the trigger switch 1 74 to cut off the power to the electromagnet 2 21 , and the wedge block 18 extends out of the guide groove 19 again to limit the top surface of the limit ring 13 .

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
