[0006] Furthermore, the elastic connecting pipe and the water inlet end are connected through a clean water supply pipe and a water inlet main pipe; a first solenoid valve for controlling the state of the clean water supply pipe is provided at the connection between the clean water supply pipe and the elastic connecting pipe; the water supply equipment is connected to the water inlet main pipe through a domestic water supply pipe, and a second solenoid valve is provided at the connection between the domestic water supply pipe and the water supply equipment.

[0007] Furthermore, the elastic connecting tube is elastic, and is parallel to the upper end surface of the water supply device. The elastic connecting tube is stretched by the pulling force generated by the electromagnet on the cleaning tube, and the stretching distance of the elastic connecting tube is sufficient for the cleaning tube to move to the bottom end of the water supply device.

[0008] Furthermore, both ends of the conduit are closed, and a threaded connection port for connecting a steering tube is provided at the center position of the upper end surface of the conduit, and a pipe port with a circular structure extends downward on the bottom end surface of the conduit, each pipe port has a thread, and a cleaning pipe is respectively locked in each pipe port by a thread; the water outlet end of the cleaning pipe faces the water outlet side of the filter structure, and a fixed bracket is respectively connected to the water outlet end of each cleaning pipe.

[0009] Furthermore, the rear end diameter of the fixed bracket is smaller than the front end diameter of the fixed bracket, the connecting claw is arranged at the front middle position of the fixed bracket, and two grooves are arranged opposite to each other on the axial diameter of the cleaning booster ball, and the grooves match the connecting claws. Through the cooperation of the grooves and the connecting claws, the cleaning booster ball and the fixed bracket are rotatably connected.

[0010] Furthermore, there is a tiny gap between the end face of the cleaning booster ball close to the water outlet end of the cleaning tube and the water outlet end of the cleaning tube, and a brush is arranged on the surface of the cleaning booster ball.

[0013] Compared with the prior art, the utility model provides a smart water supply device, which has the following beneficial effects:

[0014] This kind of smart water supply device is different from the traditional smart water supply device. The traditional smart water supply system often simply sets up multiple layers of filters for filtering to ensure the water supply effect. However, as the filtered water flow increases, the dirt remaining on the surface of the filter cannot be effectively cleaned, which will cause the filter to be blocked, affecting the filtering efficiency. At the same time, it will intercept part of the water flow, resulting in a decrease in the water flow rate, affecting the water supply effect. At this time, manual intervention is required to clean the filter. Since the filter is not distributed in a unique location, a large amount of manpower is invested in cleaning the filter, which seriously wastes resources and has low work efficiency.

[0015] By adopting the smart water supply device in the present application, the filter can be self-cleaned. The tube body is adsorbed by the telescopic rod and the magnet. During the adsorption process, the elastic tube is stretched to cause the cleaning tube body to be displaced. At the same time, as water flows out of the cleaning tube body, the cleaning booster ball will block the water flow. The blocked water flow is dispersed into multiple branches to impact the cleaning booster ball, so that the cleaning booster ball rotates under the connection of the connecting claw, cleaning the surface of the filter. At the same time, as the telescopic rod is continuously retracted, the cleaning tube is driven to contact the entire filter to achieve cleaning. It has the advantages of high cleaning efficiency and low resource investment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 A smart water supply device includes a water supply device 4 for realizing water supply, and a domestic water supply pipe 2 which can be sealably connected to one end of the water supply device 4 through an electromagnetic valve, and a water outlet pipe which can be sealably connected to the end of the water supply device 4 which is not connected to the domestic water supply pipe 2 through another electromagnetic valve, and a filtering structure located in the water supply device 4 for purifying the water in the water supply device 4, wherein the end of the domestic water supply pipe 2 which is not connected to the water supply device 4 is connected to a water inlet main pipe 1. When in use, water flows from the water inlet main pipe 1 into the domestic water supply pipe 2, and the domestic water supply pipe 2 then transmits the water flow into the water supply device 4. The water entering the water supply device 4 is filtered by the filtering structure located in the water supply device 4 to meet the national domestic water standard and is finally output through the water outlet pipe.

[0024] A water flow cavity 42 is provided inside the water supply device 4, and a filter structure is placed in the water flow cavity 42. A self-cleaning structure 5 for cleaning the filter structure is provided on the water outlet side of the filter structure and located in the water supply device 4. When in use, water flows from the water inlet side of the filter structure to the water outlet side of the filter structure, and impurities are blocked on the water inlet side of the filter structure. The self-cleaning structure 5 is flushed from the water outlet side of the filter structure to the water inlet side of the filter structure, so that the dirt adhered to the filter structure falls off, thereby avoiding the problem of the filter structure being blocked and affecting the water flow rate.

[0025] The aforementioned self-cleaning structure 5 includes a cleaning structure located on the upper wall of the water flowing cavity 42, and a driving structure arranged opposite to the aforementioned cleaning structure, the driving structure includes a telescopic rod 6 embedded in the cavity between the inner wall and the outer wall of the water flowing cavity 42, a sealing ring 7 is arranged at the position where the telescopic rod 6 contacts the inner wall of the water flowing cavity 42, and a magnetic electromagnet 8 is located at the front end of the telescopic rod 6, the electromagnet 8 obtains magnetism when power is turned on and loses magnetism when power is turned off; when in use, the telescopic rod 6 has two states, extension and retraction, and the default state of the telescopic rod 6 is a fully retracted state. In this state, the top surface of the telescopic rod 6 and the inner wall surface of the water flowing cavity 42 are located on the same horizontal plane. When the telescopic rod 6 is extended by the PLC drive, its extension height is sufficient for the electromagnet 8 at the top of the telescopic rod 6 to contact the cleaning structure arranged opposite to it.

[0026] The cleaning structure includes an elastic connecting tube 9 for supplying water to the cleaning structure, a steering tube 10 connected to the water outlet end of the elastic connecting tube 9 and connected to the elastic connecting tube 9 at 90 degrees, and a manifold 101 connected to the bottom end surface of the steering tube 10 and perpendicular to the bottom end surface of the steering tube 10. The two ends of the manifold 101 are closed, and a plurality of circular structured threaded pipe openings are arranged on the bottom end surface of the manifold 101, and a cleaning tube 102 is respectively fastened in each of the pipe openings by thread locking; the water outlet of the cleaning tube 102 is opposite to the water outlet end surface of the filtering structure; in the default state, the bottom end surface of the cleaning tube 102 and the bottom end surface of the buckle for fixing the filtering structure are on the same horizontal plane.

[0027] A fixed bracket 11 is provided at the front end of each cleaning tube 102. The fixed bracket 11 is open and two connecting claws 12 are relatively provided at the front position of the fixed bracket 11. A cleaning booster ball 13 is provided in the fixed bracket 11. A groove 131 matching the connecting claw 12 is provided on the surface of the cleaning booster ball 13. When the two connecting claws 12 respectively enter their corresponding grooves 131, the cleaning booster ball 13 can be rotatably connected in the fixed bracket 11; starting from the longitudinal axis of the cleaning booster ball 13 where the groove 131 is not provided and ending at the inner edge position of the two grooves 131, a plurality of brushes 132 with soft structures are provided on the surface of the cleaning booster ball 13 within this range.

[0028] The cleaning tube 102 is made of food-grade electroplated iron, and the electromagnet 8 can be adsorbed on the outer wall of the cleaning tube 102 when it is magnetic; the water inlet of the elastic connecting tube 9 is connected to the water inlet main pipe 1 through the cleaning water supply pipe 3, and a first solenoid valve for controlling the water flow is arranged between the cleaning water supply pipe 3 and the elastic connecting tube 9; a second solenoid valve for controlling the water inlet state of the water supply equipment 4 is arranged between the domestic water supply pipe 2 and the water supply equipment 4, and the state of the first solenoid valve is opposite to the state of the second solenoid valve.

[0029] A first drain port 14 is provided on the lower end surface of the water flow cavity 42 corresponding to the water inlet side of the filter structure, and a second drain port 15 is provided on the lower end surface of the water flow cavity 42 on the water outlet side of the filter structure and located on the outside of the telescopic rod 6. A third solenoid valve is respectively installed on the surface of the first drain port 14 and the second drain port 15, and the state of the third solenoid valve is consistent with the state of the first solenoid valve; the outlet end of the first drain port 14 and the outlet end of the second drain port 15 are respectively connected to the same drainage pipe 16.

[0030] When the water supply device 4 needs to be self-cleaned, the user presses the remote control switch, which can remotely drive the PLC located in the device within a specific range to obtain a cleaning electrical signal. When the PLC obtains the signal, it controls the second solenoid valve to close. With the closing of the second solenoid valve, water no longer enters the water supply device 4. At the same time, the PLC controls the first solenoid valve to open. A micro-boosting pump is arranged between the clean water supply pipe 3 and the water inlet main pipe 1. The pressurized water flows through the first solenoid valve into the clean water supply pipe 3, and enters the elastic connecting pipe 9 connected to it in the horizontal direction through the clean water supply pipe 3. At the end of the elastic connecting pipe 9, it follows the steering pipe 10 to turn the direction to The water flows down into the manifold 101 and then flows out through the cleaning pipe 102 connected to the bottom end of the manifold 101. Since the cleaning booster ball 13 is close to the end of the cleaning pipe 102 and blocks the cleaning pipe 102, the water flow discharged from the cleaning pipe 102 will block the cleaning booster ball 13 to form multiple diversions. At the same time, since the surface of the cleaning booster ball 13 blocks the cleaning pipe 102, the water pressure in the cleaning pipe 102 becomes stronger. When the water flow contacts the surface of the cleaning booster ball 13, the cleaning booster ball 13 is pushed to rotate in the fixed bracket 11. At this time, the brush 132 on the surface of the cleaning booster ball 13 contacts the filter structure to flush the dirt at the water inlet of the filter structure.

[0031] At the same time, the telescopic rod 6 is driven by the PLC and begins to extend, and at the same time, the electromagnet 8 is energized to obtain magnetism. The electromagnet 8 comes into contact with the lower end surface of the cleaning tube 102 along with the movement of the telescopic rod 6, and is adsorbed on the surface of the cleaning tube 102. The electromagnet 8 has strong magnetism, and the elastic connecting tube 9 is elastic. The elastic tension of the elastic connecting tube 9 is less than the suction force between the electromagnet 8 and the cleaning tube 102. Therefore, when the telescopic rod 6 retracts, the electromagnet 8 can drive the cleaning tube 102 to move downward through the elasticity generated by the elastic connecting tube 9 to clean the entire filtering structure. The wastewater generated during the cleaning process is discharged into the drainage pipe 16 through the first drainage port 14 and the second drainage port 15 to achieve sewage discharge.

[0032] When the telescopic rod 6 is in a fully retracted state, the cleaning booster ball 13 and the bottom end surface of the filtering structure are on the same horizontal plane, at which time the electromagnet 8 loses its magnetism, the cleaning tube 102 loses the traction of suction, the tension of the elastic connecting tube 9 disappears and begins to retract, driving the cleaning tube 102 and the manifold 101 back to their original positions. In order to improve the stability of the cleaning tube 102 during the retraction process, a return spring 103 is provided on the surface of the steering tube 10, the upper end surface of the return spring 103 is connected to the inner wall of the through groove on the surface of the water supply device 4 for connecting the steering tube 10, the lower end surface of the return spring 103 is connected to the upper end surface of the manifold 101, and the elastic force of the return spring 103 is less than the suction between the electromagnet 8 and the cleaning tube 102.

[0033] The aforementioned filtering structure is multi-layered, and is detachably connected through the slots 41 provided in the water supply device 4. The first filtering structure 43 is used to filter the dirt of the large diameter structure. The secondary filtering structure 44 is an adsorption filtering structure, which can use activated carbon, bamboo fiber, etc. as carriers to adsorb and purify the impurities in the passing water flow; the tertiary filtering structure 45 is an ultrafiltration structure, which can filter impurities such as bacteria, viruses and heavy metals larger than 0.01 microns; the water flow flows in from the water inlet end of the first filtering structure 43 and flows out from the water outlet end of the tertiary filtering structure 45. At the same time, at least one side of the surface of the water supply device 4 can be opened and closed to facilitate the user to replace the filter screen. Since the first filtering structure 43 filters larger particles, the surface of the first filtering structure 43 is easy to be dirty. Therefore, the best setting position of the self-cleaning structure 5 is between the first filtering structure 43 and the secondary filtering structure 44; at the same time, in order to prevent the sewage discharged from the drainage pipe 16 from polluting the water outlet end of the water supply device, the direction of the drainage pipe 16 is opposite to the water outlet port of the water supply device 4.

[0034] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
