Abstract: A rotatable fixing structure of a water spray device, the water spray device contains: a housing. The housing includes a base, a cap, and a cavity. The base has a support sheet and a fence. The support sheet has an internal face and an external face. The internal face of the support sheet has a circular post and a wear resistant washer. The external face has a notch, and the cap has at least one inlet and at least one outlet. An impeller is accommodated in the cavity and includes multiple vanes and a receiving orifice for accommodating the circular post. A reinforced heat conductor is accommodated in the notch. The reinforced heat conductor includes a first segment and a second segment. The first segment extends into the circular post over the internal face of the base, and the second segment is exposed outside the external face.

Abstract: A fixing structure of a spa sprayer, the spa sprayer comprises: a body, a holder, and a water spray unit. The body includes an insertion segment, a connection segment, a motor, a holder, an annular positioning section, multiple fixers, and multiple bolts. The holder has multiple orifices, the annular positioning section has multiple seats and a receiving groove, the multiple seats has a plurality of recesses, and each of the multiple seats has two opposite notches. Each of the multiple fixers includes a rotation element, a drive element, and a first rotary shaft. The rotation element has a rotatable coupling portion and an abutting portion. The rotatable coupling portion has a second rotary shaft, and the rotatable coupling portion has two opposite first apertures. The drive element has a second aperture and a threaded aperture. The water spray unit is fixed on the holder of the body.

Abstract: A spa sprayer contains: a body and a water spray unit. The spray unit including a spraying seat, a lid, and a cavity defined between the spraying seat and the lid. The spraying seat is mounted on an end of the body away from the motor and has an impeller received in the cavity. The lid has at least one inlet and two opposite outlets which are in communication with the cavity. The lid further has a spacing rib, an inflow space formed inside the spacing rib, an outflow space formed outside the spacing rib, and multiple tilted guide ribs. A tilted direction of the multiple tilted guide ribs corresponds to a rotation direction of the impeller, each of the multiple tilted guide ribs has an oblique angle, and the lid further has two stop shoulders extending from the two opposite outlets.
