Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example:

[0026] See also Figure 1-5 A pipe direct drinking water household disinfection device comprises a shell 1, a water inlet pipe 2 is arranged at one end of the shell 1, a water outlet pipe 3 is arranged at the other end, the water inlet pipe 2 is movably connected to the shell 1, and a filtering mechanism 4 is arranged in the shell 1; the water inlet pipe 2 of the device is connected to the direct drinking water inlet end, and the water outlet pipe 3 is connected to the household pipe.

[0027] The filter mechanism 4 includes a mounting shaft 401, and a water guide sheet 402 is arranged on the outside of the mounting shaft 401. The outer wall of the water guide sheet 402 is in sliding contact with the inner wall of the shell 1, and the mounting shaft 401 and the water guide sheet 402 can be taken out from the shell 1 for easy cleaning and replacement. The water guide sheet 402 has a spiral structure, and a plurality of filter components 403 are movably connected to the water guide sheet 402. Water flows through the surface of the water guide sheet 402 and is filtered by the plurality of filter components 403 in turn, thereby improving the filtering effect of the water. A plurality of grooves are provided on the top surface of the water guide sheet 402, and a mounting groove is provided on the side wall of the mounting shaft 401. One end of the filter component 403 is plugged into the mounting groove, and the bottom surface of the filter component 403 is located in the groove. The setting of the mounting groove and the groove facilitates the disassembly of the filter component 403, and the filter component 403 that needs to be replaced can be replaced separately, thereby improving the utilization efficiency of the filter component 403 and avoiding waste.

[0028] In the present application, a first limiting rod 5 is arranged on the inner wall of one end of the water outlet pipe 3 close to the shell 1, a slot is opened at the upper end of the first limiting rod 5, and the end of the installation shaft 401 is rotatably connected to the slot, and the installation position of the installation shaft 401 is limited by the setting of the first limiting rod 5.

[0029] In a possible embodiment, the installation shaft 401 is rotatably connected to the first limit rod 5. In the process of water flowing from the water inlet pipe 2 to the water outlet pipe 3, since the water guide plate 402 is a spiral structure and the filter assembly 403 is vertically arranged, the impact of water on the filter assembly 403 during the flow of water will cause the water guide plate 402 and the filter assembly 403 to rotate around the installation shaft 401, driving the water flow to rotate, thereby improving the purification efficiency, and no power mechanism is required, saving resources.

[0030] In the present application, a second limiting rod 6 is provided on the inner wall of one end of the water inlet pipe 2 close to the shell 1 , and the second limiting rod 6 is rotatably connected to the installation shaft 401 .

[0031] The second limiting rod 6 has an installation cavity 601, and a driving mechanism is arranged in the installation cavity 601, and the output shaft of the driving mechanism is plugged into and matched with the installation shaft 401. The driving mechanism is used to drive the installation shaft 401 to rotate, thereby increasing the water flow speed.

[0032] In the present application, the driving mechanism includes a worm wheel 602 and a worm 603. A rotating shaft 604 is provided through the middle of the worm wheel 602. The rotating shaft 604 is rotatably connected to the installation cavity 601. A prism 605 is connected to the lower end of the rotating shaft 604. A connecting groove 404 is provided at the top of the installation shaft 401. The prism 605 matches the connecting groove 404. The worm 603 is meshed with the worm wheel 602. The worm 603 is rotatably connected to the installation cavity 601, and the middle axis of the worm 603 extends to the outside of the water inlet pipe 2. A motor 606 is provided outside the water inlet pipe 2. The output shaft of the motor 606 is connected to the middle axis of the worm 603. The motor 606 is used to drive the worm 603 and the worm wheel 602 to rotate. The rotation of the worm wheel 602 drives the rotating shaft 604 and the prism 605 to rotate. The prism 605 is plugged into the installation shaft 401, so that the entire filtering mechanism 4 can rotate.

[0033] In the present application, multiple groups of ultraviolet lamps 8 are provided on the outer wall of the mounting shaft 401 and the inner wall of the housing 1 to sterilize the water with ultraviolet rays.

[0034] In the present application, an end cap is provided at the end of the water inlet pipe 2, and the end cap is sleeved on the outer end of the shell 1. A sealing strip 7 is provided inside the end cap, and the sealing strip 7 can be sealed and connected with the shell 1. Through the connection between the end cap and the end of the shell 1, it is convenient to remove the end cap, and then take out the filter mechanism 4 inside the shell 1, so as to facilitate cleaning or replacement of the filter mechanism 4.

[0035] Working principle: When the device is in use, the water inlet pipe 2 of the device is connected to the direct drinking water inlet end, and the water outlet pipe 3 is connected to the household pipe. After the water enters the water inlet pipe 2, it flows through the surface of the water guide plate 402, and passes through multiple filter components 403 in sequence to filter the water multiple times. At the same time, multiple groups of ultraviolet lamps 8 installed on the outer wall of the shaft 401 and the inner wall of the shell 1 are used to purify the water to improve the filtering effect of the water.

[0036] The water guide sheet 402 of the present application has a plurality of grooves on its top surface, and the side wall of the installation shaft 401 has an installation groove. The installation grooves and the grooves are arranged to facilitate the removal of the filter assembly 403. The filter assembly 403 that needs to be replaced can be replaced separately, thereby improving the utilization efficiency of the filter assembly 403 and avoiding waste. The vertical positions of both ends of the installation shaft 401 are limited by the first limiting rod 5 and the second limiting rod 6, so as to facilitate the rotation of the entire filter mechanism 4. The rotation of the filter mechanism 4 can utilize the impact of the water flow on the filter assembly 403, so that the water guide sheet 402 and the filter assembly 403 rotate around the installation shaft 401, drive the water flow to rotate, improve the purification efficiency, and do not require a power mechanism, saving resources. At the same time, the drive mechanism can also be used to drive the installation shaft 401 to rotate.
