Patent Application - SHOWER HEAD > Claims

1. A shower head comprising a case shaped with an inlet, a flow channel and at least one outlet, the flow channel which connects the inlet and the outlet enabling water to flow through, wherein the shower head is characterized in that it also comprises: a hydroelectric generator, installed inside the case which generates electricity for power supply when water flows through;a motor, installed inside the case which forms a power circuit together with the hydroelectric generator;a brush, being in a gearing relation with the motor, the brush making one of two movement—rotation and vibration, with the rotation of the motor;wherein when users turn on the water tap, water goes through the hydroelectric generator inside the shower head and the motor drives the brush to make one of two movements—rotation and vibration; accordingly, the shower head allows the users not to only take a shower but also to have body cleaning and body massage.
- 2. The shower head of claim 1, wherein a power switch installed on the case is series-connected in a power circuit with the motor and the hydroelectric generator, and the power switch is operated for activating the power circuit, so that the brush makes one of two movements—rotation and vibration after receiving electricity from the hydroelectric generator.
- 3. The shower head of claim 1, wherein the brush installed on the case is detachable, the users can change different types of brushes to match their needs following one of two movements—rotation and vibration, which are caused by the motor.
- 4. The shower head of claim 1, wherein the shower head is adapted for being installed with a rotating transmission mechanism which comprises a first gear, a second gear, and a rotation slide switch, the first gear and the motor are in a gearing relation, a shaft extends axially from two sides of the second gear, one end of the shaft protrudes through the head portion and connects to the brush, the shaft installed in the head portion can rotate around its central axis, the rotation slide switch is installed on the case and operated to move the first gear along the axial direction, so that the first gear is able to selectively engage with the second gear.
  - 5. The shower head of claim 4, wherein the rotating transmission mechanism also comprises a rotation abutting member and a first elastic member, one end of the rotation abutting member abuts against the shaft portion of the first gear, the other end of the rotation abutting member is in a gearing relation with the rotation slide switch; when the rotation slide switch slides toward the stem portion, the first elastic member abutted between the first gear and the motor causes the first gear to be disengaged from the second gear; when the rotation slide switch slides toward the head portion, the first gear is engaged with the second gear
    - 6. The shower head of claim 5, wherein the rotation abutting member comprises a first abutting surface, a second abutting surface and a first slant portion, the first slant portion is connected between the first abutting surface and the second abutting surface; when the first gear is disengaged from the second gear, the first abutting surface abuts against the first gear; when the first gear is engaged with the second gear, the second abutting surface abuts against the first gear.
- 7. The shower head of claim 1, wherein the shower head is adapted for being installed with a vibrating transmission mechanism which comprises a rotating member, a third elastic member, and a vibration slide switch, the brush is installed outside of the case, and one end of the brush is shaped as a shaft penetrating into the case, the rotating member is a rotating circular plate, a shaft portion extends from one side of the axle center of the rotating member, a protruding piece protrudes toward the shaft from the other side of the rotating member, the rotating member is slidably installed over the central shaft that forms a rotational relation with the motor shaft, the third elastic member is slidably installed over the shaft and abutted between the case and the shaft, the vibration slide switch is installed on the case and operated to move the transmission mechanism along the axial direction, so that the protruding piece is able to selectively hit the end of the shaft of the rotating member.
  - 8. The shower head of claim 7, wherein the vibrating transmission mechanism also comprises a vibration abutting member and a second elastic member, one end of the vibration abutting member abuts against the rotating member, the other end of the vibration abutting member is in a gearing relation with the vibration slide switch; when the vibration slide switch slides toward the stem portion, the second elastic member abutted between the rotating member and the motor causes the protruding piece of the rotating member to be disengaged from the end of the shaft; when the vibration slide switch slides toward the head portion, the protruding piece of the rotating member hits the end of the shaft.
9. The vibration abutting member comprises a third abutting surface, a forth abutting surface and a second slant portion, the second slant portion is connected between the third abutting surface and the forth abutting surface, the third abutting surface abuts against the shaft portion of the rotating member when the protruding piece of the rotating member is disengaged from the end of the shaft, the forth abutting surface abuts against the shaft portion of the rotating member when the protruding piece of the rotating member hits the end of the shaft portion.
