Abstract
A hydraulically operated toothbrush in which the flow of water from a faucet through the toothbrush handle and into the head produces rotation of a plurality of bristles mounted in the head, the bristles also being mounted for limited axially movement, and including a device for regulating the water pressure within the head to thereby assure the proper rotation of the bristles. The toothbrush may also include a siphoning tube operated by the suction created when water passes into the toothbrush, one end of the tube being inserted into the user's mouth and the other in a discharge basin. The siphoning tube may also be fitted with a mouth rinse fluid cup to introduce small amounts of fluid into the user's mouth during the brushing.
Claims11
A hydraulically operated movable bristle toothbrush comprising:
- (a) an elongated handle having a longitudinal water passage, said passage being connectable to a pressurized water source;
- (b) a head formed at one end of said handle having a main cavity and at least one channel with a flow cross-section smaller than said handle water passage, said channel having at least one opening into said cavity, said head having a plurality of openings for accepting bristles and a plurality of discharge openings;
- and
- (c) a plurality of bristle means rotatably mounted in said cavity, each said bristle means including a cylindrical bristle projecting laterally through and rotatably mounted in one of said bristle openings and including a propeller, means, said propeller means including propeller blades fixedly mounted to the portion of the bristle within the cavity whereby water discharged at high pressure from said channel against the propeller blades will rotate the bristle to effect a cleaning action.
A hydraulically operated movable bristle toothbrush comprising:
- (a) an elongated handle having a longitudinal water passage and a flexible tube connectable to a pressurized water source;
- (b) a head formed at one end of said handle having a main cavity defined by a bottom wall, four side walls including two elongated walls and front and rear walls, and a top wall, a pair of channels adjacent the two elongated side walls, each of said channels having at least one opening into said cavity, the top wall having one or more rows of openings for accepting bristles and a plurality of discharge openings for permitting the water entering the head to be discharged out of the toothbrush;
- (c) a closing member mounted within said cavity for selectively opening and closing of the discharge openings to thereby regulate the pressure in the cavity so as to maintain the cavity pressure less than the entry water pressure;
- and
- (d) a plurality of bristles, each bristle rotatably mounted in said cavity and projecting laterally through and rotatably mounted in one of said top wall openings and propellers, each propeller fixedly mounted to the portion of one of said bristles within the cavity whereby water discharged at high pressure from said channels against the propeller blades rotate the bristles to effect a cleaning action.
A hydraulic toothbrush comprising:
- (a) an elongated handle having a longitudinal water passage and a flexible tube connectable to a water faucet;
- (b) a head mounted at one end of said handle including a bottom wall, four side walls including two elongated walls and front and rear walls, and a top wall to thereby define a cavity, and at least one channel connecting the water passage and the cavity, the top wall having one or more rows of openings for accepting bristles and a plurality of discharge openings for permitting the water entering the head to be discharged out of the toothbrush;
- (c) a plurality of bristle means rotatably mounted in said cavity and projecting laterally through and rotatably mounted in one of said top wall openings and means for rotating said bristles mounted to the portion of each of said bristles within the cavity whereby water discharged at high pressure from said channel rotates the bristles to effect a cleaning action;
- and
- (d) a siphoning tube with an orifice opening to the water passage of said handle, one end of said tube being insertable into the mouth and the other end being deposited in a waste receptacle, whereby the movement of the water in the passage causes a suction in said tube to thereby remove water from the mouth and deposit it in the receptacle.
