Description

Field of the invention

The present invention relates to a shower head, especially to a shower head with a detachable top cover.

Background of the invention

Existing shower head usually comprises a main body unit, a water diversion body rotatably disposed inside the main body unit and a top cover rotatably assembled to the main body unit, the water diversion body and the top cover are relatively fixed, so that the top cover, when rotating, drives the water diversion body to rotate with respect to the main body unit, the water diversion body rotates with respect to the main body unit so as to switch the waterways. The top cover is secured to the main body unit by screws, in other case, the top cover is locked to the main body unit by a non-detachable way, so that the existing technology has below disadvantage: it needs special tools to assemble and disassemble the top cover, resulting in inconvenient.
With respect to the prior art attention is drawn to US 6 715 699 B1 . The showerhead engine assemblies disclosed therein provide different combinations and variations of continuous, deflected, pulsating sprays, and aeration spray patterns including those that are adjustable enabling wide variations in the degree of aeration of the water passing through the showerhead, enabling wide variation of the characteristics of the water spray patterns. The spray patterns include a nondeflected, nonpulsating spray pattern; a deflected nonpulsating spray pattern; a nondeflected, pulsating spray pattern; and a deflected, pulsating spray pattern, while enabling the engine assembly to be self-cleaning. For pulsating spray modes, the showerhead engine assembly includes but five plastic parts and an O-ring seal; the parts being a stator, a spinner, an engager, a pressure plate, and a faceplate, openings beings disposed in the pressure plate and faceplate to enable fluid flow therefrom. Deflecting surfaces on the faceplate enable a variety of different flow patterns. Spinner rotation starts or stops depending upon the position of the spinner relative to the stator, since the stator includes a pair of stop flanges that engage and disengage with the spinner. When the spinner is disengaged and free to rotate, water flow through passages in the spinner cause spinner rotation, creating a vortex and pulsating spray patterns.
Further, DE 103 07 073 A1 discloses a shower device including a ring which is formed by joining an external grip sleeve and an internal rod inner slider together. The inner slider is axially rotatable relative to a shower head, and provided with spring sections contacted to the face to a case.
GB 2 311 474 A discloses a spray head for a shower handset having nozzles disposed in apertures of a spray plate. At least one of the apertures has a plurality of nozzles. The nozzles are resiliently deformable allowing them to be cleaned by hand or finger pressure. The spray head may have three concentric groups of nozzles for producing normal, aerated and pulsing sprays.
From CN 201 168 657 Y a fast dismounting and easy-to-clean showerhead is known. This spray head capable of being dissembled and assembled fast and cleaned conveniently is composed of a main body, a water outlet unit, a connecting device and a sealing element; the main body is provided with a water inlet device, a water-through flow passage, an excessive water cavity, a control device arranged according to specific requirements for controlling water flow and a device for regulating gears; the water outlet unit is provided with a water outlet element, a rectifying and guiding element arranged according to specific requirements and a device for regulating gears; the connecting device is arranged at the connecting part of the main body and the water outlet unit, can be assembled and disassembled repeatedly as well as opened and locked conveniently, and has the sealing element at a connecting fit place; all elements at the interiors of the main body and the water outlet unit are in movable matching connection, the interior of the whole spray head can be disassembled through opening the connecting device, the connecting device is locked after the main body and the water outlet unit as well as the sealing element are assembled, and the whole spray head can be normally used again and reliably bear the water pressure and the force in use.
