BEST EMBODIMENT FOR CARRYING OUT THE INVENTION

Best Implementation of the Invention

[0019] The present invention is further illustrated in details hereinafter in connection with concrete embodiments. However, it should not be taken to limit the scope of the above subject of the present invention to the following embodiments. All techniques carried out based on the contents of the present invention shall be within the scope of protection of the present invention.

[0020] As shown in FIG. 2, a pair of transmission rods 5 respectively extends into rollers 3 of a brush head 1. The brush head 1 includes bristles 2 and the rollers 3, which are made of a food-grade silica gel type of soft material through integral formation by one-piece molding. Namely, the bristles 2 and the rollers 3 are an integral structure without gaps. The pair of brush heads 1 is driven by the transmission rods 5 to perform 360-degree rotation in opposite directions (see FIG. 3). End portions of the transmission rods 5 are lower than end portions of the brush heads 1. A back-flushing plate 4 is provided at a back of the pair of brush heads 1. A top end of the back-flushing plate 4 is lower than top ends of the pair of brush heads 1 (see FIG. 1). The back-flushing plate 4 has a back-flushing function. During the tooth brushing procedure, the bristles are actuated under rotation of the rollers. The washing water flow impacts the back-flushing plate 4, and the water flow is reflected backwards by the back-flushing plate 4 to further flush the oral waste on the bristles and the rollers, such that the teeth can be brushed more clean. Thus, use of the brush head device according to the present invention can attain three-in-one effects of suction, flushing, and brushing, achieving a more effective and better cleaning effect.

[0021] As shown in FIG. 4, a preferred embodiment structure of the present invention is as follows:

[0022] A pair of transmission rods 5 is respectively connected with a pair of brush heads 1. The brush heads are driven by the transmission rods to perform 360-degree rotation in opposite directions, attaining oral cleaning and care of teeth, furs, and gums, etc.

First Concrete Embodiment

Example of Cleaning of Teeth and Furs

[0023] Since the brush heads 1 according to the present invention are made of a food-grade silica gel type of soft material and perform 360-degree rotation in opposite directions (see FIG. 3), deep cleaning of locations at the teeth, the tooth gaps, gingival sulcus, occlusal surfaces, and the fur roots can be attained without injuring the gums and the soft tissues in the oral cavity. During cleaning of the teeth, when the front ends of the bristles 2 are placed in a tooth gap, each bristle 2 adjacent to a side of the tooth gap acts like a respective toothpick and rotates in a direction from the gum towards the tooth crown, rapidly cleaning the tooth gap while other bristles are cleaning the tooth face. The bristles 2 of the brush head at the other side also rotate in the direction from the gum towards the tooth crown to clean the tooth at the other side or occlusal surface without causing gum eversion or gingival laceration. Since the material of the brush heads 1 is a food-grade silica gel type of soft material, the gums will not be scratched. Furthermore, the brush heads are integrally formed to permit easy cleaning after use while avoiding hiding and breeding of bacteria between the bristles 2 and the rollers 3, thereby avoiding mutual secondary infection between the tool and the bacteria or viruses in the oral cavity.

[0024] As shown in FIG. 2, a pair of brush heads 1 made of a food-grade silica gel type of soft material is driven by a pair of transmission rods 5 to perform 360-degree rotation in opposite directions. The front ends of the bristles 2 suck toothpaste foam or mouthwash during rotation, forming a powerful sucking flow to suck oral waste away. The rear ends of the bristles 2 splash the sucked toothpaste foam or mouthwash onto the back-flushing plate, forming a powerful flush flow to flush oral waste away. Under continuous rotation of the bristles 2 and the sucking and flushing of the powerful water flows thus formed, suction, flushing, and brushing three-in-one thorough cleaning of the teeth is attained.

[0025] During cleaning of furs, a pair of brush heads 1 made of a food-grade silica gel type of soft material is driven by a pair of transmission rods 5 to perform 360-degree rotation in opposite directions. While the bristles 2 is proceeding with rolling brushing, the furs, taste buds, and lingual papillae can be hold up to expose the gaps between the fur roots. The front ends of the bristles 2 suck toothpaste foam or mouthwash during rotation, forming a powerful sucking flow to suck away oral waste in the furs. The rear ends of the bristles 2 splash the sucked water flows onto the back-flushing plate, forming a powerful flush flow to flush away oral waste in the furs. This unique cleaning approach of suction, flushing, and brushing three-in-one would be the more ideal method for cleaning the tongue, which not only deeply and thoroughly cleans the furs and fermented objects but also avoids injury to the taste buds and lingual papillae and stimulates and revives the sense of taste while attaining health-care massage on the reflective zones of the tongue.

Second Embodiment

Gum Massage

[0026] A pair of brush heads 1 made of a food-grade silica gel type of soft material is driven by a pair of transmission rods 5 to perform 360-degree rotation in opposite directions. Proper gum massage can be attained while brushing the teeth. A pair of bristles 2 is driven by a pair of transmission rods 5 to roll. The bristles 2 adjacent to an end of the gum always rotate and massage in the direction from the gum towards the crown of the tooth, no matter it is the outer gum or the inner gum and no matter it is the upper gum or the lower gum. No matter the brush heads are moved horizontally or vertically, proper gum message can be attained without contusion, sprain, eversion, or gingival laceration of the gums. Gum massage can improve blood circulation in the gums and the roots of teeth, increase the toughness and elasticity of the gums, and prevent gum breeding, gum shrinkage, periodontal disease, and gomphiasis. Furthermore, repair of tooth nerves can be effectively improved to help recovery of sensitive dentin.

Third Embodiment

Lip Care

[0027] A pair of brush heads 1 made of a food-grade silica gel type of soft material is driven by a pair of transmission rods 5 to perform 360-degree rotation in opposite directions. During cleaning of the lips, the bristles can thoroughly clean the residues in the oral cavity through rolling brushing while holding up the lip skin well to attain lip massage to thereby improve the blood circulation at the lips, which not only attains cleaning of the lips but prevents dry, cracked lips and slack lip muscles, achieving an effect of restoring youth and health.
