Self-cleaning top-spraying device

Abstract

The invention relates to the technical field of top-spraying sprinklers, particularly to a self-cleaning top-spraying device. The device comprises a body, a water outlet panel and a cleaning needle disk, wherein the water outlet panel is arranged on the body; a water inlet is formed in the body; water outlet holes are formed in the water outlet panel; a rotating shaft is arranged on the water outlet panel; the cleaning needle disk comprises a rotating disk and a needle disk; the rotating shaft is sleeved with the rotating disk rotatably; the needle disk is clamped below the rotating shaft and can move relative to the rotating disk; cleaning needles corresponding to the water outlet holes are arranged on the needle disk; a fan blade structure which drives the rotating disk to rotate under current scour is arranged on the rotating disk; a spiral lifting platform which is used for increasing the horizontal height of the rotating disk when the rotating disk rotates is arranged on the water outlet panel; and a limiting device which limits the rotating of the needle disk and doesn't limit up-and-down motion of the needle disk is arranged on the water outlet panel. The self-cleaning top-spraying device solves the problem of the service life of an existing return spring and makes the whole structure simple; and lifting and dropping of the cleaning needles is realized through opening and closing of water currents, so that self-cleaning after a shower each time is realized.

Description

technical field [0001] The invention relates to the technical field of top spray showers, in particular to a self-cleaning top spray device. Background technique [0002] China Patent No.: 201410516738.3 discloses a top spray cleaning device, including a body, a water outlet panel, a cleaning needle, a lever and a lever driving mechanism; Placed in the chamber; there is a water outlet hole on the water outlet panel, and the cleaning needle is movable relative to the water outlet panel, corresponding to the water outlet hole; the force end of the lever is connected to the lever driving mechanism, the force end is connected to the cleaning needle, and the lever driving mechanism is provided with a reset spring; The lever driving mechanism drives the lever to swing, and the stressed end of the lever drives the cleaning needle to separate from or insert into the water outlet hole.

AI Technical Summary

Problems solved by technology

Since the top spray is often used more frequently, using the return spring as a spare part requires high precision requirements. Otherwise, once the spring is deformed after a long period of use, the cleaning needle cannot be cleaned or separated from the water outlet.

Moreover, the use of a lever driving mechanism to realize lever swing also has relatively large defects, namely, the structure is complex, the parts are prone to fatigue, and are prone to deformation, thereby reducing the cleaning effect or the effect of water discharge.
