[0011] In the scale rotary sleeve of foam sprayer, the outer circumferential surface of the inner end of the water outlet connector has an annular mounting boss, the outer circumferential surface of the mounting boss is provided with a key groove, the decorative part has a mounting hole, the mounting boss is located in the mounting hole, the hole wall of the mounting hole has a flat key embedded in the key groove, and one end of the flow guide sleeve abuts against the end face of the mounting boss and blocks the port of the key groove. The decorative part is circumferentially limited by the key connection between the decorative part and the mounting boss. After the flow guide sleeve is installed on the water outlet connector, the decorative part is clamped and positioned, which ensures stable installation and prevents displacement of the decorative part.

[0012] In the scale rotary sleeve of the foam sprayer, a steel ring is sleeved and fixed on the inner end of the rotary sleeve, and the scale is arranged on the outer circumferential surface of the steel ring.

[0013] In the scale rotary sleeve of the foam sprayer, the inner end of the rotary sleeve is provided with an annular mounting portion, the outer circumferential surface of the mounting portion is provided with a clamping convex strip arranged along the axial direction of the mounting portion, the inner circumferential surface of the steel ring is provided with a clamping groove matched with the clamping convex strip, and the clamping convex strip is clamped in the clamping groove.

[0014] In the scale rotary sleeve of the foam sprayer, the inner end of the rotary sleeve is provided with an annular mounting portion, the outer circumferential surface of the mounting portion is provided with a clamping convex strip arranged along the axial direction of the mounting portion, the inner circumferential surface of the steel ring is provided with a clamping groove matched with the clamping convex strip, and the clamping convex strip is clamped in the clamping groove.

[0015] Compared with the prior art, the scale rotary sleeve of the foam sprayer has the following advantages: the structure adjusts the foam spraying state by rotating the rotary sleeve; during rotation, the scale on the rotary sleeve rotates, while the mark is fixed; when the foam sprayer is used for the first time, the mark points to the scale value; when the foam sprayer is used again, the rotary sleeve is rotated to make the mark point to the specified scale value, so that the adjustment convenience of the foam spraying state is greatly improved, time and labor are saved, and the convenience of using the foam sprayer is improved.
