DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.

(10) With reference to FIGS. 1-4, a spa sprayer according to a preferred embodiment of the present invention comprises a body 10 and a water spray unit 20.

(11) The body 10 includes a motor 11 and a fixing unit 12 connected with an end of the motor 11 and configured to fix the body 10 on a peripheral wall of a foot spa tub.

(12) The water spray unit 20 includes a spraying seat 21, a lid 22 connected with the spraying seat 21, and a cavity 23 defined between the spraying seat 21 and the lid 22.

(13) The spraying seat 21 is mounted on an end of the body 10 away from the motor 11, and the spraying seat 21 has an impeller 211 received in the cavity 23 and driven by the motor 11 to rotate, and the impeller 211 has multiple blades 2111 extending radially along a rotation direction of the impeller 211 and formed in an arc shape.

(14) The lid 22 has at least one inlet 221 defined around a center thereof and has two opposite outlets 222 formed proximate to a peripheral side of the lid 22, wherein the at least one inlet 221 and the two opposite outlets 222 are in communication with the cavity 23. The lid 22 further has a spacing rib 223 defined among the two opposite outlets 222 and the at least one inlet 221 and on a surface of the lid 22 facing the cavity 23, a inflow space 224 formed inside the spacing rib 223, an outflow space 225 formed outside the spacing rib 223, and multiple tilted guide ribs 226 radially extending to the outflow space 225 from the spacing rib 223, wherein a tilted direction of the multiple tilted guide ribs 226 corresponds to a rotation direction of the impeller 211, each of the multiple tilted guide ribs 226 has an oblique angle , and the oblique angle is within 20 degrees to 40 degrees (in this embodiment, the oblique angle is 30 degrees). The lid 22 further has two stop shoulders 227 extending from the two opposite outlets 222 corresponding to a rear portion of the rotation direction of the impeller 211.

(15) Referring to FIGS. 5-7, the spa sprayer is mounted on the peripheral wall of the foot spa tub by using the fixing unit 12 of the body 10 so that the motor 11 of the body 10 drives the impeller 211 of the water spray unit 20 to rotate, and the impeller 211 rotates to draw water into the cavity 23 via the at least one inlet 221 and the inflow space 224. Thereafter, the water is pressurized by the impeller 211 to flow into the outflow space 225 of the lid 22, and the water in the outflow space 225 is guided, accelerated, and pressurized by ways of the multiple tilted guide ribs 226 and the two stop shoulders 227 to spray out of the two opposite outlets 222 of the lid 22 forcefully, thus supplying and swirling the water in the foot spa tub. Therefore, the spa sprayer has following advantages:

(16) The lid 22 further has a spacing rib 223 by which the inflow space 224 and the outflow space 225 are spaced to reduce interface of water supply and discharge, and the multiple tilted guide ribs 226 radially extend to the outflow space 225 from the spacing rib 223, such that when the spa sprayer sprays the water, the water in the outflow space 225 is guided, accelerated, and pressurized by ways of the multiple tilted guide ribs 226 and the two stop shoulders 227 to spray out of the two opposite outlets 222 of the lid 22 forcefully and rapidly, thus supplying and swirling the water in the foot spa tub to enhance user's blood circulation and metabolism.

(17) While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
