The supporting part 4 can be a conduit with smooth radian, the other end 32 of the hose 3 can be connected with the resetting piece 5, and the resetting force direction can be turned through the smooth radian of the supporting part 4 and converted into the upward pulling force on the water outlet part 2. It will of course be appreciated that the support member 4 may alternatively not be provided with a smooth curvature if a downward pulling force is required for resetting the outlet 2. In the embodiment of the present invention, the reset member 5 is specifically exemplified by a weight member having a through hole, through which the other end 32 of the hose 3 is fixed by being assembled, and the other end 32 of the hose 3 is arc-shaped, and the reset force is realized by means of the weight force of the weight member.

The concave guiding surface 42 is smoothly divergent from inside to outside, and the cross-sectional shapes of the convex guiding surface 22 and the concave guiding surface 42 are smooth curves eccentric in at least one radial direction (see fig. 10C and 10D); under the action of the restoring force of the restoring piece 5, the first guide structure 21 and the second guide structure 41 can guide to perform radial alignment and axial rotation movement, so that the water outlet part 2 is aligned and attached with the supporting part 4.
As shown in fig. 6, the first guide structure 21 of the water outlet 2 is a guide convex surface 22, and the second guide structure 41 of the support member 4 is a guide concave surface 42 that is clearance-fitted with the gap. Thus, after the two are completely attached by the guiding alignment, the guiding structure can be fully accommodated in the front end of the supporting member 4, and the inner space of the front end of the supporting member 4 can be fully utilized. It should be understood that the convex-concave configuration of both the first guide structure 21 and the second guide structure 41 may also be switched as desired, e.g. the first guide structure 21 is provided as a concave guide surface and the second guide structure 41 is provided as a convex guide surface.
As shown in the figure, when the water outlet 2 is abutted against the support member 4 during the withdrawal and return of the water outlet 2, the guide convex surface 22 is fitted into the guide concave surface 42 provided on the end surface of the support member 4. The circular curve of the eccentric radial direction of the outer shape surface of the guiding convex surface 22 of the water outlet part 2 can be utilized to match with the circular curve of the eccentric radial direction of the inner cavity guiding concave surface 42 of the second guiding structure 41, the guiding convex surface 22 and the inner cavity guiding concave surface 42 are similar in shape and size and have parallel matching gaps, when the guiding convex surface 22 falls into the guiding concave surface 42, if not aligned, the guiding convex surface 22 and the guiding concave surface 42 have 2 unbalanced small contact points, balance cannot be achieved, at the moment, the water outlet part 2 with the guiding convex surface 22 automatically rotates along the inner cavity surface of the guiding concave surface 42 to guide and reset, the guiding convex surface 22 is forced to fall into the inner cavity surface completely, and finally, the two curved surfaces are parallel, and the end surface of the water outlet part 2 is attached to the end surface of the shower nozzle socket 43.
According to the current understanding, the two guiding surfaces of the drawing type water outlet device provided by the embodiment of the invention can be directly formed through the die, other guiding parts do not need to be assembled again or secondarily formed, and the automatic resetting guiding structure has the advantages of simple structure and low cost. And because there are no other assembled parts. The device also has the advantages of stable structure and low failure rate.
The at least one radial eccentric smooth curve refers to at least one radial eccentric, the eccentric refers to a circle center eccentric to form a non-circular shape so as to have the capability of direction selection, and the outline is a smooth closed curve so as to be convenient for smooth guiding and sliding. At least one rounded curve eccentric in the radial direction is, for example, so-called cam-shape, oval-shape.
According to an embodiment of the present invention, the sectional shapes of the guide convex surface 22 and the guide concave surface 42 are rounded curves symmetrically eccentric in the radial direction, similar to a symmetrical cam. The two directions can be aligned selectively, which gives the user more options.

Further, the direction of the spray switching button 23 can be selected by selecting one end in the Y-axis or X-axis direction of the elliptical shape of the guide convex surface 22 so as to be directed to the spray switching button 23 by the Y-axis, and alignment is performed based on this. It should be understood that the position of the spray switching button 23 is not necessarily completely consistent with the direction of the elliptical shape of the guiding convex surface 22, and the position of the spray switching button 23 may have a certain angle with the Y-axis or X-axis direction, so long as the angle is consistent with the angle of the shower socket preset at the opening of the supporting member, so as to finally achieve the normal reset of the spray switching button 23.
That is, by the return guide action of the directional guide convex surface 22 and the guide concave surface 42, when the water outlet 2 is pulled out from the support member 4 and returned to the original alignment position, the water outlet 2 and the front end of the support member 4 are aligned with each other with a specific shape or member.
