[0011] By adopting the above technical scheme, when water is supplied into the steady flow tank, the water passes through the conductive sleeve, so that impurities in the water are removed through electrolysis, the impurities in the water are adsorbed on the conductive sleeve, the purification of the water quality is realized, the attachment of impurities in the steady flow tank is reduced, and then the water quality is improved. When the impurities attached to the conductive sleeve are too much, the first driving member works to drive the rotating wheel to rotate, the rotating wheel drives the conductive sleeve to rotate, the conductive sleeve is separated from the water inlet pipe, and another conductive sleeve is communicated with the water inlet pipe, so as to ensure the purification effect of the conductive sleeve and improve the water quality purification efficiency.

When the cleaned conductive sleeve needs to be moved to the position communicated with the water inlet pipe, the rotating wheel reversely rotates, so that the half-tooth ring drives the gear to reversely rotate, so as to drive the scraping ring to reset by the lead screw, at this time, the lead screw can limit the scraping ring, so that the scraping ring is not easy to be displaced by the impact of water flow.

[0021] Optionally, two half-tooth rings are arranged, the two half-tooth rings are symmetrically arranged in the purification tank, and the plurality of gears are divided into two groups, one group of gears is used for meshing with one half-tooth ring, and the other group of gears is used for meshing with the other half-tooth ring.

[0051] Each through hole 2321 is fixedly connected with a conductive sleeve 233. In the embodiment, the conductive sleeve 233 is made of a material with good conductivity and corrosion resistance, and the conductive sleeve 233 is connected with an electrolysis device, and the electrolysis device is electrically connected with an external control circuit.

[0052] Referring to FIG. 2, one end of the water inlet pipe 11 extending into the purification tank 21 is in communication with the conductive sleeve 233, and a sealing ring 111 is installed on the end face of the water inlet pipe 11 close to the conductive sleeve 233.

[0055] When the impurities attached to the conductive sleeve 233 are too much, the first driving member 231 works to drive the runner 232 to rotate, the runner 232 drives the conductive sleeve 233 to rotate, so that the conductive sleeve 233 is separated from the water inlet pipe 11, and another conductive sleeve 233 is in communication with the water inlet pipe 11, thereby facilitating to ensure the purification effect of the conductive sleeve 233 and improve the water quality purification efficiency.

[0056] Referring to FIG. 2, a plurality of through grooves 2322 are formed on the runner 232 along the axis direction thereof, and one through groove 2322 penetrates one conductive sleeve 233. The cleaning assembly 22 includes a second driving member 221 and a scraping ring 222, and the second driving member 221 includes a lead screw 2211, a half-tooth ring 2212, and a gear 2213. The number of the lead screws 2211 is equal to the number of the through grooves 2322, one lead screw 2211 is inserted into one through groove 2322 and rotationally connected with the runner 232, and one end of the lead screw 2211 extends out of the through groove 2322. In the embodiment, the lead screw 2211, the half-tooth ring 2212, and the gear 2213 are made of a material resistant to wear and corrosion.

[0057] The number of the gears 2213 is equal to the number of the lead screws 2211, one end of one lead screw 2211 extending out of the through groove 2322 is coaxial and fixedly connected with one gear 2213, so that the gear 2213 can drive the lead screw 2211 to rotate when the gear 2213 rotates.

[0058] Referring to FIGS. 2 and 3, two half-tooth rings 2212 are symmetrically arranged in the purification tank 21 and coaxially arranged with the rotating wheel 232, one gear 2213 is arranged for meshing with one half-tooth ring 2212, and the other gear 2213 is arranged for meshing with the other half-tooth ring 2212.

[0059] Referring to FIG. 2, the number of scraper rings 222 is equal to the number of conductive sleeves 233, and one scraper ring 222 is slidingly arranged in one conductive sleeve 233 and abuts against the inner wall of the conductive sleeve 233. In this embodiment, the scraper ring 222 can be made of silica gel material. In other embodiments, the scraper ring 222 can be replaced by a filter screen.

[0060] The scraper ring 222 is fixedly connected with a sliding block 2221, the sliding block 2221 is inserted into the through groove 2322 and threadedly connected with the lead screw 2211, so that the lead screw 2211 can limit the scraper ring 222 to prevent the scraper ring 222 from being displaced by the impact of water flow. In this embodiment, the sliding block 2221 is made of an insulating and corrosion-resistant material.

[0061] Referring to FIGS. 2 and 3, when the first driving member 231 drives the rotating wheel 232 to rotate, the rotating wheel 232 drives the conductive sleeve 233 to rotate, so that one conductive sleeve 233 is separated from the water inlet pipe 11. At this time, the gear 2213 meshes with the half-tooth ring 2212, and the rotating wheel 232 continuously rotates to drive the other conductive sleeve 233 to a position communicated with the water inlet pipe 11. In this process, the half-tooth ring 2212 drives the gear 2213 to rotate, the gear 2213 drives the lead screw 2211 to rotate, so that the lead screw 2211 drives the scraper ring 222 to move in the conductive sleeve 233 through the sliding block 2221, thereby facilitating the cleaning of impurities in the conductive sleeve 233 by the scraper ring 222 to ensure the adsorption effect of the conductive sleeve 233.

[0062] In this embodiment, the rotating wheel 232 only needs to rotate 180 degrees to switch the two conductive sleeves 233, and when the rotating wheel 232 rotates 180 degrees in the forward direction, one scraper ring 222 can move away from the first driving member 231 to scrape the impurities in the conductive sleeve 233, and the other scraper ring 222 can move towards the first driving member 231 to reset the scraper ring 222. When the rotating wheel 232 reverses 180 degrees, the two scraper rings 222 move in opposite directions, so that the rotating wheel 232 does not need to rotate one revolution to complete the switching and cleaning of the conductive sleeve 233, thereby reducing unnecessary rotation of the rotating wheel 232 to some extent, which is conducive to improving the switching and cleaning efficiency of the conductive sleeve 233.

[0063] In other embodiments, the second driving member 221 can also be a pneumatic cylinder or an electric push rod to drive the scraper ring 222 to move.

[0064] Referring to FIG. 2, the scraping ring 222 is integrally formed with a guide slope 2222 on each side, which is inclined towards the middle of the scraping ring 222, so as to better guide the impurities out of the conductive sleeve 233 during the movement of the scraping ring 222, and reduce the possibility of the scraping ring 222 being displaced due to excessive impact force of the water flow during the water supply.

[0065] Referring to FIG. 2, the sliding block 2221 is fixedly connected with a flexible sealing band 223, which is slidingly inserted into the through slot 2322 and disposed close to the conductive sleeve 233. The end of the flexible sealing band 223 away from the sliding block 2221 extends out of the through slot 2322 and is fixedly connected with the purification tank 21, and the flexible sealing band 223 avoids the water inlet pipe 11.

[0066] Referring to FIGS. 2 and 3, when the conductive sleeve 233 is in communication with the water inlet pipe 11, the scraping ring 222 is located at the initial position, at which the flexible sealing band 223 is in a taut state, so as to facilitate the sealing of the through slot 2322 by the flexible sealing band 223, thereby improving the sealing performance of the overall structure and reducing the possibility of water leakage from the through slot 2322 in the conductive sleeve 233.

[0067] When the scraping ring 222 drives the sliding block 2221 to move, the sliding block 2221 can drive the flexible sealing band 223 to move, so as to gradually separate the flexible sealing band 223 from the through slot 2322, thereby reducing the possibility of interference of the flexible sealing band 223 with the movement of the sliding block 2221.

[0068] In other embodiments, the flexible sealing band 223 can be detachably connected with the purification tank 21 and the sliding block 2221, so as to facilitate replacement of the flexible sealing band 223.

[0069] Referring to FIG. 1, the steady flow tank 1 is remotely connected with a water outlet pipe 12, and the water outlet pipe 12 is connected with a plurality of household pipelines 13. A water pump 3 is installed on each household pipeline 13, so that the water in the steady flow tank 1 can enter the water outlet pipe 12, be pressurized by the water pump 3, and flow into each household pipeline 13.

[0070] The implementation principle of the non-negative pressure water supply equipment with water purification function in the embodiment is that when the water inlet pipe 11 supplies water to the steady flow tank 1, the water passes through the conductive sleeve 233, so as to be electrolyzed to adsorb the impurities in the water on the conductive sleeve 233, thereby reducing the impurities entering the steady flow tank 1.

[0071] When the impurities attached to the conductive sleeve 233 are too much, the first driving member 231 works to make the rotating wheel 232 drive the conductive sleeve 233 to rotate, so that one conductive sleeve 233 is separated from the water inlet pipe 11 and another conductive sleeve 233 is communicated with the water inlet pipe 11. In this process, the gear 2213 and the half-tooth ring 2212 are engaged with each other, so that the half-tooth ring 2212 drives the gear 2213 to rotate, the gear 2213 drives the sliding block 2221 to move through the screw rod 2211, and the scraping ring 222 is driven to move by the sliding block 2221, so that the scraping ring 222 scrapes the impurities in the conductive sleeve 233, thereby realizing the cleaning of the conductive sleeve 233.

[0074] The limiting strip 2231 is integrally formed on the flexible sealing band 223 and is slidably inserted into the limiting groove 2331, so that the limiting strip 2231 can support the flexible sealing band 223 to effectively prevent the flexible sealing band 223 from being deviated or twisted during movement, and can effectively improve the sealing effect of the overall structure to reduce the possibility of water leakage from the through groove 2322.

[0075] The limiting strip 2231 is made of flexible material, so that the limiting strip 2231 can deform with the flexible sealing band 223.
