The working principle is as follows: because incrustation scale or particles are easily attached to the surface of the filter screen 12 and the content of meshes, the filter screen cannot be cleaned in time, water flow passing is easily influenced, the motor 7 drives the filter 8 to rotate, the circular hole 11 synchronously displaces while the filter 8 rotates, the circular hole 11 is shielded by the annular brush 9 to change water quantity, the annular brush 9 can clean the filter screen 12 in the circular hole 11 while shielding the circular hole 11, the adjustment of the water flow and the filtration of a water source are realized, the filter screen is prevented from being blocked, and the vibration of the purification mechanism and the driving of the switching mechanism can be driven to be switched;
when a plurality of existing valves stop supplying water, residual water inside the valves still overflows from the water outlets of the valves and cannot be instantly closed, so that water resource waste is caused, water pump equipment connected with a water inlet pipe is opened at the outside to provide pressure for water flow, the provided pressure pushes the closing plate 16 to move towards the fixed seat 10, the closing plate 16 drives the other closing plate 16 to contract under the meshing connection effect of the gear 14 and the rack 15, the water flow normally flows out to the water outlet pipe 5 through the circular hole 11, when the external water pump equipment is closed, the valves lose the pressure and stop the water flow, the water outlets of the valves are closed, the spring 18 is instantly and elastically reset to push the closing plate 16 to tightly press the circular hole 11, the cleaning brush 17 moves along with the closing plate 16 to scrape the surface of the limiting net 20, dirt attached to the surface or particles blocking meshes are removed, the structure of the device can achieve a water stop self-closing function, water is saved, the residual water inside is prevented from continuously flowing out, the water is inconvenient to collect, and a purification mechanism can be cleaned, and the blockage of the purification mechanism is prevented;
the water flow easily contains elements harmful to human bodies, the harmful elements need to be purified by some substances such as medical stones, but the medical stones are accumulated together for a long time, not only can the water source not be fully purified, but also can cause self-attached dirt, the position of the medical stone 21 is limited by the limiting net 20, the medical stone 21 is prevented from being lost or blocked by random movement of the medical stone 21, the filter 8 rotates to drive the medical stone 21 to move, the medical stone 21 impacts the elastic sheet 22 to rebound, the position of the medical stone 21 is limited, the medical stone 21 can conveniently purify the water source, the medical stone 21 impacts the elastic sheet 22 through the rotation of the filter 8, the medical stone 21 is impacted by the elastic force of the elastic sheet 22 to vibrate the medical stone 21, and then the adjacent medical stones 21 are mutually collided and rubbed, the dirt on the surface of the medical stone 21 is removed, and the purifying effect of the medical stone 21 is improved;
when the closed plate 16 is driven to move by water pressure, the closed plate 16 drives the cleaning brush 17 to clean the limiting net 20, so that the surface of the limiting net 20 is cleaned, and the phenomenon that the limiting net 20 is blocked due to the attachment and the condensation of dirt is prevented;
the filter 8 drives the driving conical gear 25 to rotate through the first rotating rod 23, the driving conical gear 25 drives the meshed driven conical gear 26 to change the rotating direction, the change of the kinetic energy direction is realized, the stirring fan 28 is convenient to drive to stir and crush, and the adapter 29 is used for switching a water inlet pipe, water flow is not easy to flow out when the valve is opened, the driven conical gear 26 drives the stirring fan 28 to rotate through the second rotating rod 27, the stirring fan 28 is used for forming ice from water or crushing larger substances cleaned by the annular brush 9, the normal circulation of the water flow is realized, and the problems of freezing and blockage of the larger substances in the valve body 1 are solved;
the connection of the different solutions of two pipelines or the conversion of hot water and cold water need to be realized, the second rotating rod 27 drives the adapter 29 to rotate, the adapter 29 completes the switching of the first inlet pipe 3 or the second inlet pipe 4 through rotation, the quick switching of the inlet pipes is realized, and the adaptation to different use conditions is facilitated.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
