Abstract

A hand-held shower head includes a fixing element, a rotating element and a first spring. The fixing element is provided with a water inlet channel and a first water outlet channel for flushing water. The rotating element is rotatably connected with the fixing element and is provided with a water passage and a second water outlet channel for spraying water. The first spring is disposed between the fixing element and the rotating element. When the rotating element rotates to a first position, the water passage communicates with the water inlet channel and the first water outlet channel, and the first spring is elastically deformed. When the rotating element is released from the first position, the first spring elastically recovers to drive the rotating element to rotate to a second position, and the second water outlet channel communicates with the water inlet channel.

First claim

What is claimed is:

1. A hand-held shower head, comprising:
a fixing element, provided with a water inlet channel, a first water outlet channel and a first abutting surface, wherein the water inlet channel is provided with a water inlet, the first water outlet channel is provided with a first water outlet, and a water passing area of the first water outlet is smaller than a water passing area of the water inlet;
a rotating element, rotatably connected with the fixing element around a rotation axis and provided with a water passage, a second water outlet channel, and a second abutting surface, wherein the second water outlet channel is provided with a plurality of second water outlets, the second abutting surface is opposite to the first abutting surface in a circumferential direction; when the rotating element rotates to a first position, the water passage is in communication with the water inlet channel and the first water outlet channel; when the rotating element rotates to a second position, the second water outlet channel is in communication with the water inlet channel;
a first spring, arranged between the first abutting surface and the second abutting surface, configured to be elastically deformed when the rotating element is rotated from the second position to the first position, and elastically recovered when the rotating element is released from the first position to drive the rotating element to rotate to the second position; and
a blocking member, wherein the fixing element is further provided with a sliding slot having a position-limiting wall, when a water outlet direction of the first water outlet faces upward relative to a horizontal plane, the sliding slot is not parallel to the horizontal plane and the position-limiting wall is located at a lower end of both ends of the sliding slot;
the rotating element is further provided with an insert block, the insert block is configured to be inserted into the sliding slot when the rotating element is rotated to the first position; and
the blocking member is driven by gravity to roll or slide in the sliding slot, and the insert block is allowed to be inserted into the sliding slot only when the blocking member is far from the position-limiting wall.

2. The hand-held shower head according to claim 1 , wherein the rotation axis is perpendicular to the water outlet direction of the first water outlet and parallel to a water outlet direction of each of the second water outlets.

3. The hand-held shower head according to claim 2 , further comprising a circlip, wherein one of the fixing element and the rotating element is provided with a protrusion shaft with the rotation axis as an axis, and a first annular recess is provided on a side wall of the protrusion shaft;
the other one of the fixing element and the rotating element is provided with a bore for insertion of the protrusion shaft, and an insertion end of the bore is provided with a chamfer for pressing the circlip to deform the circlip, a wall of the bore is provided with a second annular recess;
the circlip is disposed in the first annular recess and extends into the second annular recess, such that the rotating element and the fixing element are in position-limiting cooperation in a direction along the rotation axis.

4. The hand-held shower head according to claim 3 , wherein the circlip is in a shape of a ring with an opening, and is wavy after being expanded in the circumferential direction.

5. The hand-held shower head according to claim 1 , wherein an extending direction of the sliding slot is the same as the water outlet direction of the first water outlet, a side wall of the sliding slot is provided with a sliding slot opening, and the sliding slot opening is adapted to be passed through by the insert block so as to insert into the sliding slot.

6. The hand-held shower head according to claim 5 , wherein the fixing element comprises a body, a water outlet base and a fixing base, the body is provided with a handle and a top cover;
the water inlet channel is disposed on the handle, the top cover is fixedly connected to the handle at a position away from the water inlet;
the water outlet base is fixedly connected to the top cover and located at a position away from the handle, the first water outlet channel is disposed at the water outlet base, the first water outlet channel is further provided with a first water passage port, the first water passage port is opened on a bottom surface of the water outlet base away from the top cover, the water outlet base is provided with an accommodating recess extending in the circumferential direction for accommodating the first spring, one end of the accommodating recess forms the first abutting surface, and the other end of the accommodating recess is provided with an accommodating recess opening;
the fixing base is fixedly connected to the top cover, the protrusion shaft and the sliding slot are disposed on the fixing base, and the protrusion shaft extends in a direction away from the top cover.

7. The hand-held shower head according to claim 6 , wherein the rotating element comprises a water diversion base, a water outlet cover and a water outlet sleeve, the water passage and the second water outlet channel are both disposed on the water diversion base, the water passage is provided with a second water passage port and a third water passage port, the second water outlet channel is provided with a fourth water passage port, the third water passage port is disposed on an end surface of the water diversion base facing the water outlet base, and is in sealed communication with the first water passage port when the rotating element rotates to the first position;
the second water passage port and the fourth water passage port are all arranged on an outer circular surface of the water diversion base and arranged in the circumferential direction, the second water passage port is in sealed communication with the water inlet channel when the rotating element rotates to the first position, and the fourth water passage port is in sealed communication with the water inlet channel when the rotating element rotates to the second position;
the water diversion base is provided with a protrusion extending toward the water outlet base, the protrusion is adapted to be inserted into the accommodating recess through the accommodating recess opening, and a surface of the protrusion facing the first abutting surface forms the second abutting surface; the water diversion base is further provided with a shaft sleeve extending toward the fixing base, the bore is disposed on the shaft sleeve;
the insert block is disposed on the water diversion base; the water outlet cover is provided with a radially extending operating handle; the water outlet cover and the water diversion base are non-rotatably engaged with each other, and clamp the water outlet sleeve therebetween.

8. The hand-held shower head according to claim 7 , wherein the water diversion base is further provided with a third water outlet channel and a fourth water outlet channel, the third water outlet channel is provided with a fifth water passage port and a plurality of third water outlets, a water outlet direction of the third water outlets is parallel to a water outlet direction of the second water outlets;
