Person is equal to preset first threshold value, and section is arc-shaped, and the convex ribs 12 coordinate with the water inlet pipe water outlet 13, and support institute
Gushing arm 3 is stated to rotate around the water outlet.The convex ribs 12 are arc-shaped, can reduce the contact area with water inlet pipe 2, that is, revolve
3 inside of gushing arm is contacted with the only line of water inlet 7 when turning, contact surface very little, therefore spin friction very power；The convex ribs 12 are with upper and lower two
Circle is advisable, separated in the convex ribs 12, is divided into several sections, the gap can allow short grained pollutant or silt logical
It crosses, prevents from being stuck in 12 position of convex ribs, and then make 3 clamping stagnation of gushing arm；The open position up and down be staggered, while stop shower water from
Close gap outflow；The flow flows into 3 water inlet 13 of gushing arm from water inlet pipe water outlet 11.
3 top water inlet 13 of the gushing arm coordinates with water inlet pipe 2, and boss 15 coordinates gushing arm 3 with connecting shaft 4 below, gushing arm 3
Rotated around connecting shaft 4,2 water outlet 11 of water inlet pipe, then the height that about 3 gushing arm coordinates be exactly 2 water inlet of gushing arm, 12 convex ribs 12 and
The distance of 3 boss hole 15 of gushing arm, is set as h；The connecting shaft 4 and 3 boss hole of gushing arm, 15 clearance fit, the fit clearance are
A is advisable in 0.1mm-1mm；3 water inlet 13 of the gushing arm and 2 water outlet of water inlet pipe, 11 clearance fit, the fit clearance are that b is big
In the fit clearance a of connecting shaft 4 and 3 boss hole 15 of gushing arm, b is advisable in 0.2mm-1.5mm；The gushing arm 3 rotate when simultaneously around
2 water outlet 11 of water inlet pipe and connecting shaft 4 rotate, and 3 both ends of gushing arm will appear shakings when the rotation, and downward shift height is H, root
It is gushing arm length according to ratio value H=L*b/h, L.But due on identical axial line, and rotary gap is small, therefore when rotating or so
Gradient is small, though very little if amplified gushing arm both ends downward shift degree H by gushing arm length, therefore gushing arm 3 and cover board can be reduced
Gap between inner cover plate 102.
As shown in figure 3, the 11 outer end border of water outlet of the water inlet pipe 2 is provided with seal groove 10, the seal groove 10 is set
Be equipped with sealing ring 6, the water outlet 11 is connect by the sealing ring 6 with cover board 1, can prevent water in sink body or steam into
Enter inside cover board 1.
As shown in figure 4, the gushing arm 3 is provided at least one power hole 16 and at least one spray apertures 17, the power
16 position of hole is less than or equal to default second threshold at a distance from 3 end of the gushing arm and opening direction is revolved with the gushing arm 3
Turn direction on the contrary, the spray apertures 17 are arranged in 3 lower surface of gushing arm, and direction is diagonally downward.
16 position of power hole described in the utility model embodiment is close proximity to 3 end of gushing arm and opening direction and gushing arm 3
On the contrary, providing rotary power for 3 cleaning showers of gushing arm, the power hole 16 is at least arranged one, can also be opposite for direction of rotation
It is arranged multiple, the flow is ejected along power hole 16, provides reaction force, and gushing arm is pushed to do rotation fortune along power hole negative direction
It is dynamic；The spray apertures 17 are arranged in gushing arm lower surface, and direction is diagonally downward, and water is flowed out through spray apertures, is ejected into cleaned material
Surface can take away pollutant, reach cleaning purpose.
The gushing arm attachment device of the utility model embodiment is rotated using gushing arm 3 around connecting shaft 4, and connecting shaft 4 uses
3 friction coefficient of gushing arm of stainless steel, smooth outer surface and plastic parts is small, and the friction of stainless steel and plastic parts relative to
Fretting wear between the plastic parts of two same materials is small, not will increase friction coefficient；Coefficient of thermal expansion is small simultaneously, by water temperature
Influence is smaller, will not reduce friction gap, frictional force is avoided to increase, therefore the rotating speed in rotation process of gushing arm 3 is avoided seriously to become
Slow and stagnation behavior occurs, and ensure that good cleaning performance.
Due to connection inserting part 5 and 2 direct injection molding of water inlet pipe, then connection inserting part 5 and 2 water outlet of water inlet pipe, 11 concentricity
It is very high, while 3 boss hole 15 of gushing arm and gushing arm 3 water inlet, 13 same concentricities are very high, pass through connecting shaft 4 and 5 spiral shell of connection inserting part
Line connects, then can ensure good selection concentricity, make 3 smooth rotation of gushing arm.
3 top water inlet 13 of the gushing arm coordinates with water inlet pipe 2, and boss hole 15 coordinates gushing arm 3 with connecting shaft 4 below, phase
For common directly buckle or rotary buckle, 3 water inlet 13 of gushing arm stretches into 2 water outlet 11 of water inlet pipe, and about 3 gushing arm coordinates
Connection distance be significantly increased, can accordingly reduce the magnification ratio of 3 both ends upper and lower displacement of gushing arm, simultaneously because gushing arm 3 with into
The left and right offset amplitude very little of fit clearance all very littles of water pipe 2, connecting shaft 4, i.e. gushing arm 3 when rotated, further reduced
The amplitude that teetertotters at 3 both ends of gushing arm improves 3 rotational stabilization of gushing arm.Gap gushing arm 3 and inner cover plate can be maximized simultaneously
102 spacing reduce the connection space of gushing arm 3, after cover board 1 is opened, facilitate picking and placeing for bowl basket or food basket, improve operating experience.
Although the revealed embodiment of the utility model is as above, its content is only to facilitate understand the utility model
Technical solution and the embodiment that uses, be not intended to limit the utility model.Any the utility model technical field
Interior technical staff can be in the form of implementation under the premise of not departing from the utility model revealed core technology scheme
With any modification and variation are made in details, but protection domain defined by the utility model still must be with appended claims
Subject to the range of restriction.
