A parent-child showerhead includes a wall-mounted showerhead, a hand-held showerhead, and a showerhead bracket. The wall-mounted showerhead is fixed on a conduit extending from a wall and connects to the hand-held showerhead via a hose. The showerhead bracket is provided for the hand-held showerhead to hang thereon. The wall-mounted showerhead has a water diverter disposed therein for controlling the spray water from the wall-mounted showerhead or the hand-held showerhead or from both of them. The water diverter has an adjusting knob for changing a direction of the water flow, and the adjusting knob is located on the wall-mounted showerhead at side close to a user, which is convenient for users to operate. The showerhead bracket is disposed at a lower position of the wall-mounted showerhead, and has a receptacle. The receptacle is in a pivoted state to adjust an angle and provide the hand-held showerhead to be engaged therein.

A rodent guard configured to be attached to an end of a gutter for preventing rodents from entering the gutter, climbing the gutter to the roof and entering a house is disclosed. The rodent guard may include a gutter receiving opening at one end and a cover receiving opening at a second end generally opposite to the first end. A perforated cover formed from a rigid material may be removably attached to the rodent guard body at the second end that enables the cover to be removed from the base during use such that debris within the gutter can be easily removed from the gutter. The perforated cover may be sized to allow water to pass through the cover, but prevent rodents from entering the gutter through the cover.

The invention relates to a roadway flood protection and traffic barrier which provides a smooth upper surface for vehicles, pedestrians, etc. and is thin enough to be mounted to the surface of an existing roadway or parking garage ramp, for example. A hinge mechanism is disclosed which facilitates the provision of a smooth roadway surface as well as a tight seal. A locking strut is provided that keeps the gate panels raised even in case of air pressure loss and which is remotely controllable.

The invention provides an integrated initial rainwater draining well, which is a device capable of draining certain millimeters of initial rainwater on an appointed water catchment panel and separating out later clean rainwater so as to greatly enhance the quality of the recycled rainwater. The integrated initial rainwater drainage well consists of a buried rainwater inspection well and a storage pool; the rainwater inspection well is connected with a water inlet pipe and a water outlet pipe; a bevel board precipitation structure is arranged at the bottom of the storage pool; a drainage pipe is arranged at a position a certain distance from the pool bottom; a lower sink and a flow baffle plate are arranged between the rainwater inspection well and the storage pool; at the highest water level, short flow is formed between the water inlet pipe and the water outlet pipe, so the later rainwater passes through the rainwater inspection well and directly enters the water outlet pipe to be recycled; the initial rainwater is drained in the storage pool; and after the rainwater runoff stops, the rainwater in the storage pool is slowly drained from the drainage pipe and stopped at the effective lowest water level. The integrated initial rainwater draining well has the advantages that: the structure is simple, the well operates in an unmanned way, a power supply is saved, the well is easy to maintain, polluted rainwater can be collected effectively, the drainage pipe is hardly blocked, the blocked drainage pipe is easy to smooth after being blocked and the buried drainage pipe is buried so that the appearance of the environment is not influenced.

The present invention provides a fuel cell stack with a water drainage structure, which can effectively drain condensed water and prevent water from flowing into unit cells by combining an end anode plate (EAP) and an end cathode plate (ECP), which are formed by modifying an anode plate (AP) and cathode plate (CP) respectively. In doing so, the modified anode plate (AP) and cathode plate (CP) are converted into a dummy cell which is positioned at the end portions of the fuel cell stack.
