Non-negative pressure water supply equipment cleverly utilizes the existing residual pressure of the municipal water supply network, and performs secondary pressurized water supply by means of series superposition, while ensuring that the pressure of the municipal water supply network is always maintained above the preset protection pressure, thereby ensuring the stability and safety of water supply.

[0003] Regarding the above-mentioned related technologies: During the long-term water supply process, impurities in the water will gradually accumulate, causing scale to gradually deposit inside the water supply equipment, which will have an adverse effect on the water quality of the water supply. Summary of the invention

[0004] In order to reduce the possibility of deterioration in water quality, the present application provides a non-negative pressure water supply device with a water purification function.

[0005] The present application provides a non-negative pressure water supply device with water purification function, which adopts the following technical solution:

[0006] A non-negative pressure water supply device with water purification function, comprising:

[0007] A simmering tank, wherein the simmering tank is connected to a water inlet pipe;

[0008] The purification mechanism includes a purification box, a cleaning component and a purification component. The purification box is arranged on the water inlet pipe, and the cleaning component and the purification component are respectively arranged in the purification box. One end of the water inlet pipe extends into the purification box and is connected with the purification component. The cleaning component is connected to the purification component. The cleaning component is used to clean the purification component, and the purification component is used to purify water quality.

[0009] By adopting the above technical scheme, the water inlet pipe can be connected to the municipal water supply network so that water can flow into the steady flow tank through the purification mechanism, and the purification component can absorb impurities in the water, and the cleaning component can clean the impurities on the purification component, which is beneficial to reduce the possibility of excessive impurities adsorbed on the purification component, resulting in a reduction in the ability of the purification component to adsorb impurities, and then facilitate the use of the purification component to effectively purify the water quality, thereby reducing the possibility of water quality degradation and improving the water supply efficiency to a certain extent.

[0010] Optionally, the purification component includes a first driving member and a rotor, the first driving member is arranged in the purification box, the rotor is rotatably connected in the purification box and connected to the output end of the first driving member, a plurality of through holes are opened on the rotor around its own axis, a conductive sleeve is provided in each of the through holes, one end of the water inlet pipe is attached to the rotor and connected to the conductive sleeve, and the cleaning component is used to clean the conductive sleeve.

[0011] By adopting the above technical solution, when water is supplied to the simmering tank, the water will pass through the conductive sleeve, so that impurities in the water can be removed by electrolysis, so that the impurities in the water are adsorbed on the conductive sleeve to purify the water quality, reduce the attachment of impurities in the simmering tank, and thus help improve the water quality of the water supply. When there are too many impurities attached to the conductive sleeve, the first driving member works to drive the rotating wheel to rotate, and the rotating wheel drives the conductive sleeve to rotate, so that the conductive sleeve is separated from the water inlet pipe, and the other conductive sleeve is connected to the water inlet pipe, which is conducive to ensuring the purification effect of the conductive sleeve and improving the water purification efficiency.

[0012] Optionally, a sealing ring is filled between the water inlet pipe and the rotating wheel.

[0013] By adopting the above technical solution, the sealing ring between the water inlet pipe and the impeller can effectively prevent water leakage at the connection point, ensure the sealing of the water flow during the purification process, and improve the water purification effect of the equipment.

[0014] Optionally, the cleaning assembly includes a second driving member and a scraper ring, the number of the scraper rings is equal to the number of the conductive sleeves, one of the scraper rings is slidably disposed in one of the conductive sleeves and fits against the inner wall of the conductive sleeve, the second driving member is disposed in the purification box and connected to the scraper ring, and when the wheel rotates, the second driving member can drive the scraper ring to move in the conductive sleeve.

[0015] By adopting the above technical solution, when there are too many impurities attached to the conductive sleeve, the first driving member works to drive the rotating wheel to drive the conductive sleeve to rotate, so that the conductive sleeve with too many impurities attached is separated from the water inlet pipe, and the new conductive sleeve is connected to the water inlet pipe. At this time, the second driving member can drive the scraper ring inside the conductive sleeve with too many impurities attached to move, so that the scraper ring can be used to scrape off the impurities attached to the inner wall of the conductive sleeve, thereby facilitating the cleaning of the conductive sleeve.

[0016] Optionally, guide slopes are respectively provided on both sides of the scraper ring, and the guide slopes are inclined toward the middle direction of the scraper ring.

[0017] By adopting the above technical solution, the setting of the guiding slope is beneficial to reducing the possibility of excessive impact force of water flow on the scraper ring, which may cause displacement of the scraper ring. On the other hand, during the movement of the scraper ring, the guiding slope can effectively guide the impurities to concentrate in the middle to facilitate the cleaning of the impurities, thereby helping to improve the cleaning efficiency and effect.

[0018] Optionally, the rotating wheel is provided with a plurality of through slots along its own axial direction, and one of the through slots passes through one of the conductive sleeves;

One end of the screw extends out of the through slot and is coaxially provided with a gear. A slider is provided on the scraper ring. The slider is inserted in the through slot and is threadedly connected to the screw. When the rotating wheel rotates, the gear can engage with the semi-toothed ring.

And when the conductive sleeve needs to be moved to a position connected to the water inlet pipe after cleaning, the wheel rotates in the opposite direction, so that the half-toothed ring drives the gear to rotate in the opposite direction, so that the gear drives the scraper ring to reset through the screw. At this time, the screw can limit the scraper ring so that the scraper ring is not easily displaced due to the impact of water flow.

[0021] Optionally, two semi-toothed rings are provided, and the two semi-toothed rings are symmetrically arranged in the purification box, and the multiple gears are divided into two groups, one group of gears is used to mesh with one semi-toothed ring, and the other group of gears is used to mesh with the other semi-toothed ring.

[0022] By adopting the above technical solution, when the rotating wheel realizes the switching of the conductive sleeve by reciprocating rotation, the setting of the two half-toothed rings can make the scraper ring move back and forth in the conductive sleeve to clean the conductive sleeve, so that the rotating wheel does not need to rotate one circle to complete the switching and cleaning of the conductive sleeve, thereby reducing unnecessary rotation of the rotating wheel to a certain extent, which is beneficial to improving the switching efficiency of the conductive sleeve.

[0023] Optionally, a flexible sealing belt is connected to the slider, the flexible sealing belt is slidably inserted in the through slot and arranged close to the conductive sleeve, one end of the flexible sealing belt away from the slider extends out of the through slot and is connected to the purification box, and the flexible sealing belt is used to close the through slot.

[0025] Optionally, a limiting groove is provided on the conductive sleeve along its own axial direction, the limiting groove is communicated with the through groove, a limiting strip is provided on the flexible sealing belt, and the limiting strip is slidably inserted in the limiting groove.

[0026] By adopting the above technical solution, the limit strip is slidably inserted in the limit groove, which can effectively prevent the flexible sealing belt from deflecting or twisting during movement to reduce the possibility of the flexible sealing belt interfering with the movement of the slider, and can effectively improve the sealing effect of the overall structure to reduce the possibility of water leakage from the through groove.

[0027] Optionally, a collection box is detachably connected to the purification box, and the collection box is arranged below the rotating wheel.

[0028] By adopting the above technical solution, a detachable collection box is arranged in the purification box, and the collection box is arranged under the rotor, so as to collect and process impurities generated in the process of cleaning the conductive sleeve by the scraper ring, simplify the equipment maintenance process, and improve the water purification effect and ease of use of the equipment.

The simmering tank 1 is connected with a water inlet pipe 11, which is used to connect to the municipal water supply network so that tap water can flow into the simmering tank 1 through the water inlet pipe 11. The purification mechanism 2 is arranged on the water inlet pipe 11, and the purification mechanism 2 is used to purify the water quality to reduce the attachment of impurities in the simmering tank 1, thereby facilitating the improvement of the water quality of the water supply.

[0050] Reference Figure 2 The purification mechanism 2 includes a purification box 21, a cleaning component 22 and a purification component 23. The purification box 21 is arranged on the water inlet pipe 11, the cleaning component 22 and the purification component 23 are arranged in the purification box 21 respectively, and one end of the water inlet pipe 11 extends into the purification box 21 and communicates with the purification component 23, the cleaning component 22 is connected to the purification component 23, the cleaning component 22 is used to clean the purification component 23, and the purification component 23 is used to purify the water quality, so as to achieve the effect of continuously purifying the water source and cleaning impurities.

[0051] Reference Figure 2, the purification assembly 23 includes a first driving member 231 and a rotating wheel 232. The first driving member 231 is installed in the purification box 21, and the rotating wheel 232 is rotatably connected in the purification box 21 and fixedly connected to the output end of the first driving member 231. In this embodiment, the first driving member 231 is a motor, so that the first driving member 231 is used to drive the rotating wheel 232 to rotate. In other embodiments, the first driving member 231 can also be set as a hydraulic motor.

[0052] Reference Figure 3 A plurality of through holes 2321 are provided on the rotating wheel 232 around its own axis direction, and the axis of each through hole 2321 is parallel to the axis of the rotating wheel 232. In this embodiment, there are two through holes 2321, and the two through holes 2321 are symmetrically arranged.

[0053] A conductive sleeve 233 is fixedly connected in each through hole 2321. In this embodiment, the conductive sleeve 233 is made of a material with good conductivity and corrosion resistance, and the conductive sleeve 233 is connected to the electrolysis device, and the electrolysis device is electrically connected to the external control circuit.

[0054] Reference Figure 2 The end of the water inlet pipe 11 extending into the purification box 21 is connected to the conductive sleeve 233, and a sealing ring 111 is installed on the end surface of the water inlet pipe 11 close to the conductive sleeve 233. The sealing ring 111 is used to fill the gap between the water inlet pipe 11 and the runner 232 to enhance the sealing performance and prevent water from leaking from the connection. In this embodiment, the sealing ring 111 can be made of a rubber material with strong water resistance.

[0055] In other embodiments, the sealing ring 111 may not be provided, and the water inlet pipe 11 is made to fit closely with the rotating wheel 232 .

[0056] Reference Figure 1 and Figure 2 When water is supplied to the swirl tank 1 through the water inlet pipe 11, the water will pass through the conductive sleeve 233 so that the impurities in the water are adsorbed on the conductive sleeve 233 through electrolysis, so as to purify the water quality and reduce the attachment of impurities in the swirl tank 1, which is beneficial to improve the water quality of the water supply.

[0057] When there are too many impurities attached to the conductive sleeve 233, the first driving member 231 works to drive the rotor 232 to rotate, and the rotor 232 drives the conductive sleeve 233 to rotate, so that the conductive sleeve 233 is separated from the water inlet pipe 11, and the other conductive sleeve 233 is connected to the water inlet pipe 11, which is beneficial to ensure the purification effect of the conductive sleeve 233 and improve the water purification efficiency.

[0058] Reference Figure 2 and Figure 4, a plurality of through slots 2322 are provided on the rotating wheel 232 along its own axial direction, and a through slot 2322 passes through a conductive sleeve 233. The cleaning assembly 22 includes a second driving member 221 and a scraper ring 222, and the second driving member 221 includes a screw 2211, a half-toothed ring 2212 and a gear 2213. Among them, the number of screws 2211 is equal to the number of through slots 2322, a screw 2211 is inserted in a through slot 2322 and is rotatably connected to the rotating wheel 232, and one end of the screw 2211 extends out of the through slot 2322. In this embodiment, the screw 2211, the half-toothed ring 2212 and the gear 2213 are all made of wear-resistant and corrosion-resistant materials.

[0059] The number of the gears 2213 is equal to the number of the screw rods 2211 . One screw rod 2211 extends out of one end of the through slot 2322 and is coaxially and fixedly connected to a gear 2213 , so that the screw rod 2211 can be driven to rotate when the gear 2213 rotates.

[0060] Reference Figure 2 and Figure 3 There are two half-toothed rings 2212, which are symmetrically installed in the purification box 21, and the two half-toothed rings 2212 are coaxially arranged with the rotating wheel 232. One gear 2213 is used to mesh with one half of the toothed rings 2212, and the other gear 2213 is used to mesh with the other half of the toothed rings 2212.

[0061] Reference Figure 2 and Figure 4 The number of scraper rings 222 is equal to the number of conductive sleeves 233, and one scraper ring 222 is slidably disposed in one conductive sleeve 233 and fits against the inner wall of the conductive sleeve 233. In this embodiment, the scraper ring 222 can be made of silicone material. In other embodiments, the scraper ring 222 can also be replaced by a filter.

[0062] Reference Figure 4 and Figure 5 The scraper ring 222 is fixedly connected with a slider 2221, which is inserted into the through groove 2322 and threadedly connected to the screw rod 2211, so that the screw rod 2211 can limit the scraper ring 222, so that the scraper ring 222 is not easily displaced due to the impact of the water flow. In this embodiment, the slider 2221 is made of insulating and corrosion-resistant materials.

[0063] Reference Figure 2 and Figure 3When 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 and the half-toothed ring 2212 are meshed with each other, and the rotating wheel 232 continues to rotate to rotate the other conductive sleeve 233 to a position connected with the water inlet pipe 11. In this process, the half-toothed ring 2212 can drive the gear 2213 to rotate, and the gear 2213 drives the screw rod 2211 to rotate, so that the screw rod 2211 can drive the scraper ring 222 to move in the conductive sleeve 233 through the slider 2221, so as to facilitate the use of the scraper ring 222 to clean the impurities in the conductive sleeve 233 to ensure the adsorption effect of the conductive sleeve 233.

[0064] In this embodiment, the rotating wheel 232 only needs to rotate 180 degrees to realize the switching of the two conductive sleeves 233, and when the rotating wheel 232 rotates 180 degrees forward, one scraper ring 222 can move in a direction away from the first driving member 231 to scrape the impurities in the conductive sleeve 233, and the other scraper ring 222 can move in a direction close to the first driving member 231 to reset the scraper ring 222. When the rotating wheel 232 rotates 180 degrees reversely, the two scraper rings 222 move in the opposite direction, so that the rotating wheel 232 does not need to rotate one circle to complete the switching and cleaning of the conductive sleeve 233, thereby reducing the unnecessary rotation of the rotating wheel 232 to a certain extent, which is conducive to improving the switching and cleaning efficiency of the conductive sleeve 233.

[0065] In other embodiments, the second driving member 221 may also be configured as a cylinder or an electric push rod to drive the scraper ring 222 to move.

[0066] Reference Figure 4 and Figure 6 The scraper ring 222 is integrally formed with guide slopes 2222 on both sides. The guide slopes 2222 are inclined toward the middle of the scraper ring 222, which can better guide impurities to be discharged from the conductive sleeve 233 during the movement of the scraper ring 222, and are beneficial to reducing the possibility of excessive impact force of the water flow on the scraper ring 222 during the water supply process, resulting in displacement of the scraper ring 222.

[0067] Reference Figure 2 and Figure 5 A flexible sealing belt 223 is fixedly connected to the slider 2221, and the flexible sealing belt 223 is slidably inserted in the through groove 2322 and arranged close to the conductive sleeve 233. One end of the flexible sealing belt 223 away from the slider 2221 extends out of the through groove 2322 and is fixedly connected to the purification box 21, and the flexible sealing belt 223 is arranged to avoid the water inlet pipe 11.

[0068] Reference Figure 2 and Figure 3When the conductive sleeve 233 is connected to the water inlet pipe 11, the scraper ring 222 is located at the initial position. At this time, the flexible sealing tape 223 is in a tight state, so it is convenient to use the flexible sealing tape 223 to close the through groove 2322, thereby improving the sealing performance of the overall structure and reducing the possibility of water in the conductive sleeve 233 leaking from the through groove 2322.

[0069] Reference Figure 2 and Figure 5 When the slider 2221 moves, the slider 2221 can drive the flexible sealing belt 223 to move, so that the flexible sealing belt 223 gradually separates from the through groove 2322, thereby reducing the possibility of the flexible sealing belt 223 interfering with the movement of the slider 2221.

[0070] In other embodiments, the flexible sealing belt 223 may also be detachably connected to the purification box 21 and the slider 2221 , so as to facilitate replacement of the flexible sealing belt 223 .

[0071] Reference Figure 1 The simmering tank 1 is connected to a water outlet pipe 12 , and the water outlet pipe 12 is connected to a plurality of household inlet pipes 13 . A water pump 3 is installed on each household inlet pipe 13 , so that the water in the simmering tank 1 can enter the water outlet pipe 12 , and is pressurized by the water pump 3 , and flows into each household inlet pipe 13 .

[0072] The implementation principle of the non-negative pressure water supply device with water purification function in the embodiment of the present application is: when water is supplied to the simmering tank 1 using the water inlet pipe 11, the water will pass through the conductive sleeve 233 so that the impurities in the water are adsorbed on the conductive sleeve 233 through electrolysis, thereby reducing the impurities entering the simmering tank 1.

[0073] When there are too many impurities attached to the conductive sleeve 233, the first driving member 231 works, so that 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, and the other conductive sleeve 233 is connected to the water inlet pipe 11. In this process, the gear 2213 and the half-toothed ring 2212 are meshed with each other, so that the half-toothed ring 2212 drives the gear 2213 to rotate, and the gear 2213 drives the slider 2221 to move through the screw rod 2211, and the slider 2221 drives the scraper ring 222 to move, so that the scraper ring 222 scrapes the impurities in the conductive sleeve 233, thereby cleaning the conductive sleeve 233.

[0074] Example 2: Reference Figure 7 and Figure 8 The difference between this embodiment and the first embodiment is that a limiting groove 2331 is provided on the conductive sleeve 233 along its own axial direction, and the limiting groove 2331 is connected to the through groove 2322 .

[0075] A limit strip 2231 is integrally formed on the flexible sealing strip 223, and the limit strip 2231 is slidably inserted in the limit groove 2331, so that on the one hand, the limit strip 2231 can support the flexible sealing strip 223 to effectively prevent the flexible sealing strip 223 from deflecting or twisting during movement, and on the other hand, it can effectively improve the sealing effect of the overall structure to reduce the possibility of water leakage from the through groove 2322.

[0076] The limiting strip 2231 is made of a flexible material, so that the limiting strip 2231 can be deformed along with the flexible sealing belt 223 .

[0077] Example 3: Reference Fig. 9 and Fig.10 The difference between this embodiment and embodiment 1 is that a collection box 211 is detachably connected to the purification box 21, and the collection box 211 is arranged below the rotating wheel 232, so that after the scraper ring 222 scrapes away the impurities in the conductive sleeve 233, the impurities can fall into the collection box 211.

[0078] In this embodiment, the collection box 211 is slidably connected to the purification box 21 , and the collection box 211 and the purification box 21 are fixed by snaps, so that the collection box 211 can be easily installed or removed, and the impurities collected in the collection box 211 can be easily cleaned.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
