Description
- 1. Field of the Invention
- The present invention relates to a toothbrush, more particularly to the structure of a water-jet toothbrush having a replaceable bristle head and a spiral jet head that can thoroughly clean the tooth crevices and massage the gums.
- One of the most common and widely used dental instruments for promoting oral hygiene is the toothbrush. There are different kinds of toothbrushes for the user to choose, for example, manual, electric and hydro-powered toothbrushes. This invention relates to a hydro-powered toothbrush and, in particular, relates to a water-jet toothbrush.
- 2. Description of the Related Art
- In general, the structure of a conventional water-jet toothbrush as shown in FIG. 1, mainly comprises a
bristle head 1 being fixed on the front part of the handle, a fluid supply being associated with the handle, the fluid supply being connectable to a source of fluid, and several water-jet exit orifices 2 being emerged evenly in the bristles on the toothbrush head. After the toothbrush is used, some residues may be stored up in the bristles and therefore clog the tiny discharge orifices. Further, since the discharge orifices are spread evenly in the bristles, the water jet exiting from the discharge orifices cannot be concentrated to provide a strong power to clean the tooth crevices and massage the gums effectively. Additionally, the handle part of the toothbrush is integrally united with the head, with the water passage of the head continuing through the handle. It is not economic to replace the whole toothbrush just because the bristle head is worn out. - Therefore, in summation of the above description of the structural design of the toothbrush, particularly a water-jet toothbrush is the research and development subject for enhancement. The inventor of the present invention based on years of experience in the related industry conducted extensive research to enhance the structure of a water-jet toothbrush herein which is hereby submitted for patent application.
- The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a replaceable bristle head and a spiral jet head that can be conveniently replaced to meet all individual requirements. It is not necessary to replace the whole toothbrush, just because the bristle head is worn out, as with prior art toothbrushes. It is another object of the present invention to provide a spiral jet head to clean the tooth crevices and massage the gums more effectively and therefore reduce oral diseases.
- The present invention discloses an improved structure of a water-jet toothbrush, comprising a hollow base in the front part of the handle to receive and store the replaceable bristle head firmly, a hollow pipe being associated with the rear part of the handle, a source of water being connectable to the rear part of the pipe, a water controller be fixedly mounted to connect the handle and the pipe and to control the flowing of water toward the jet head at the anterior portion of the toothbrush head, a water passage being formed and extended axially from the pipe to the handle and curved inwards within the toothbrush head to connect with the jet head, thereby such curvature direct a strong water stream to clean the residues stored on the tooth crevices and massage the gums effectively.
- To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and its performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
- Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiment. The description is made with reference to the accompanying drawings, in which:
- FIG. 1 shows the illustrative structure of a conventional water-jet toothbrush.
- FIG. 2 shows the three-dimensional diagram of a preferred embodiment of the present invention.
- FIG. 3 shows the three-dimensional diagram of the disassembled parts of a preferred embodiment of the present invention.
- FIG. 4 shows the sectional diagram of the preferred embodiment of the present invention.
- FIG. 5 is an enlarged diagram showing the handle with a replaceable bristle head and a spiral jet head of the present invention.
- FIG. 6 is a diagram showing the replaceable bristle head being stored in the hollow base of the handle according to a preferred embodiment of the present invention.
- FIG. 7 is a diagram showing the operation of a spiral jet head of the present invention.
- Referring to FIG. 2, a water-jet toothbrush is shown having a
replaceable bristle head 30, aspiral jet head 15 at the anterior portion of the toothbrush head A, and ahandle 10 being extended to connect with ahollow pipe 20. The other end of thepipe 20 is connectable to a source of water B. - Referring to FIGS. 3 and 4, the front part of he handle10 is a
hollow base 101 to receive and store areplaceable bristle head 30 firmly. Anelastic plate 31 is disposed at one, or both, end of thereplaceable bristle head 30. A blocking bottom is projected from the elastic plate to fit theblocking hole 103 at the lateral wall of thehollow base 101, so that thebristle head 30 and thehandle 10 are clipped together to prevent a rotary movement, as shown in FIG. 6. - Referring to FIGS. 3 and 4 again, at the anterior end of the toothbrush head A is a
groove 102 being covered with aspiral jet head 15.Several discharge orifices 150 are symmetrically allocated on thespiral jet head 15. In order to prevent leakage, ananti-leakage ring 151 is mounted around thespiral jet head 15. A C-shaped locatingpin 16 is clipped into thegroove 102 to fixedly fasten thespiral jet head 15, as shown in FIG. 5. Awater passage 100 is formed and extended axially from thepipe 20 to thehandle 10 and curved inwards within the toothbrush head to connect with thespiral jet head 15, as shown in FIG. 6, thereby such curvature direct a strong water stream to clean the tooth crevices. - Referring to FIG. 7, under the
discharge orifice 150 are several drop-shaped channels 151 being connectable with thewater passage 100. The water stream from thewater passage 100 through the drop-shaped channels 15 imparts an outward pressure to push thespiral jet head 15, causing thespiral jet head 15 to rotate and produce different water jets to massage the gums effectively. Further, since thespiral jet head 15 is separated from thebristle head 30, thedischarge orifices 150 are prohibited from being clogged by the residues. - Referring to FIG. 3, a
water controller 40 is fixedly mounted to connect the handle10 and thepipe 20, and to control the flowing of water toward thespiral jet head 15. Thewater controller 40 consists two portions, afront connector 41 and arear connector 42. At the front end of thefront connector 41 is awater passage 410, being associated with thehandle 10. At the outer diameter of thewater passage 410 are thethreads 411, be fixedly fastened withhandle 10. Therear connector 42 is fitted axially into thegroove 412 at the rear part of thefront connector 41. At the rear part of therear connector 42 is an extendedring 421 withthreads 423 at the outer diameter, being fastened with thescrew hole 21 of thepipe 20. Referring to FIG. 4, the drop-shaped groove 422 at the rear part of therear connector 42 is associated with thewater outlet 200 in thepipe 20 to form a contact area permitting water to pass in and out of. When thewater controller 40 is adjusted with hand from the outer diameter, the contact area of thegroove 422 and thewater passage 410 is changed, and therefore the flowing of the water is controlled. Two anti-leakage rings C are disposed before thefront connector 41 and therear connector 42 respectively to prevent leaking. - While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
