Abstract

A shower head includes a shower head body having a water inlet channel, a first leather cup, a surface cover assembly, a water dispensing plate located between the shower head body and the surface cover assembly, and an adjusting device having a driving mechanism and a rotating mechanism. A first water outlet communicating with the water inlet channel penetrates the first leather cup. Two sides of the water dispensing plate respectively cooperate with the shower head body and the surface cover assembly to enclose an installation cavity and a water outflow cavity. The water dispensing plate has a first water passage hole communicating with the water outflow cavity. The driving mechanism is rotatably connected to the shower head body. The rotating mechanism is located inside the installation cavity and abuts against the first leather cup and the water dispensing plate. The driving mechanism drives the rotating mechanism to rotate to adjust a water outflow area.

First claim

What is claimed is:

1. A shower head, comprising:
a shower head body, provided with a water inlet channel;
a first leather cup, hermetically fixed onto the water inlet channel, wherein a first water outlet penetrates the first leather cup, and the first water outlet communicates with the water inlet channel;
a cover apparatus;
a water dispensing plate, fixedly connected to the shower head body, located between the shower head body and the cover apparatus; wherein two sides of the water dispensing plate respectively cooperate with the shower head body and the cover apparatus to hermetically enclose an installation cavity and a water outflow cavity, and the water dispensing plate is provided with a first water passage hole communicating with the water outflow cavity; and
an adjusting device, including a driving apparatus and a rotating apparatus;
wherein the driving apparatus is rotatably connected to the shower head body and includes an operating portion at least partially exposed outside the shower head body, and
the rotating apparatus is located inside the installation cavity and hermetically abuts against the first leather cup and the water dispensing plate, the rotating apparatus is provided with a second water passage hole, and the operating portion drives the driving apparatus to drive the rotating apparatus to rotate, so as to adjust a water outflow area which is formed by the overlapped area of the first water outlet and the second water passage hole,
wherein the driving apparatus includes a rocker button and a driving plate,
wherein the rocker button forms the operating portion and is rotatably connected to a cavity wall of the installation cavity,
one end of the driving plate is fixed onto the rocker button, and the other end of the driving plate extends into the installation cavity of the shower head body and is provided with a driving rack, and
the rotating apparatus includes a transmission rack rotatably meshed with the driving rack,
the rotating apparatus further includes a rotation plate and a second leather cup,
wherein the rotation plate is rotatably connected to the shower head body and is located in the installation cavity, a surface of the rotation plate facing away from the water dispensing plate abuts against the first leather cup, a surface of the rotation plate facing the water dispensing plate is provided with a first installation groove that has an opening facing the water dispensing plate, and the second water passage hole is located on a bottom portion of the first installation groove,
the second leather cup is hermetically fixed inside the first installation groove and abuts against the water dispensing plate, a third water passage hole penetrates the second leather cup, and the third water passage hole is configured to communicate with the first water passage hole, and
the transmission rack has an arc shape and is fixed onto the rotation plate.

2. The shower head according to claim 1 , wherein a first rotating shaft extending towards the water dispensing plate is disposed in the installation cavity of the shower head body, and an outer wall of the first rotating shaft is provided with a limiting surface extending outwardly in a radial direction, and
the rotation plate is sleeved on the first rotating shaft and is sandwiched between the limiting surface and the water dispensing plate.

3. The shower head according to claim 2 , wherein a central position of the first rotating shaft is provided with a threaded hole penetrating the first rotating shaft, and
the water dispensing plate is sleeved on the first rotating shaft and is fixed onto the threaded hole of the first rotating shaft by a screw.

4. The shower head according to claim 1 , further comprising a plurality of elastic members,
wherein a surface of the first leather cup facing an inner cavity of the water inlet channel and a surface of the second leather cup facing the rotation plate are both provided with a plurality of protruding blocks, and an inner cavity wall of the water inlet channel and the bottom portion of the first installation groove are both provided with protruding ribs respectively opposite to the protruding blocks, and
one end of each of the elastic members is sleeved outside one of the protruding blocks, and the other end of each of the elastic members is sleeved outside a corresponding one of the protruding ribs opposite to the one of the protruding blocks.

5. The shower head according to claim 1 , wherein one end of the rotation plate facing away from the water dispensing plate is circumferentially provided with three identical positioning grooves, and one side, facing away from the positioning groove located in the middle part, of each of the two positioning grooves located in the upper part and the lower part respectively is provided with an arc-shaped blocking wall, and
an inner wall of the shower head body opposite to the positioning grooves is provided with an elastic spring plunger, and the elastic spring plunger is configured to be positioned through abutting against the positioning grooves when the rotation plate rotates.

6. The shower head according to claim 1 , wherein the cover apparatus includes a water outflow plate and a water outflow surface cover,
wherein the water outflow plate is elastic and is provided with a plurality of water outflow columns,
the water outflow surface cover is engaged with the shower head body and is provided with a plurality of fourth through holes for the water outflow columns to extend thereout, and
the water outflow plate is sandwiched between the water dispensing plate and the water outflow surface cover.

7. The shower head according to claim 6 , wherein a surface of the water dispensing plate facing the water outflow plate is provided with third protruding columns extending in a direction of the water outflow plate, and the third protruding columns and the water outflow columns are arranged in an alternating manner, and the third protruding columns are configured to press against the water outflow plate, such that the water outflow plate is closely attached to the water outflow surface cover.
