Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, 2 and 3, a water spraying toothbrush comprises a toothbrush head 1, a water inlet 2, a toothbrush handle 3, a water outlet 4 and a flexible joint part 8. Toothbrush head 1 is connected with toothbrush handle 3 and constitutes the toothbrush main part, and toothbrush handle 3 is inside to be equipped with the passageway, and the passageway is opened to have two openings to be water inlet 2 and delivery port 4 respectively in the direction towards toothbrush brush hair, water inlet 2 sets up near being close to toothbrush head 1, delivery port 4 sets up near the bottom of toothbrush handle 3, and the direction of water inlet 2 and delivery port 4 becomes certain angle with the axial cross section of toothbrush handle 3.

Referring to fig. 3, the direction of the water outlet 4 is preferably at an angle of 30 ° to the axial cross-section of the toothbrush handle 3. The direction of the water inlet 2 forms an angle of 45 degrees with the axial cross section of the toothbrush handle 3.

Referring to fig. 4 and 5, the flexible joint 8 is provided with a circular flexible joint skirt 6, a connecting pipe 7 is arranged at the lower part of the flexible joint 8, the connecting pipe 7 is hollow and is communicated with a flexible joint water inlet 5 formed in the middle of the flexible joint skirt 6, and the connecting pipe 7 is in sliding fit with the water inlet 2. The connecting pipe 7 and the end surface of the water inlet of the flexible joint part 8 form an angle of 45 degrees. The flexible joint 8 is of rubber material. Preferably, the openings of the flexible joint water inlets 5 on the flexible joint part 8 are distributed in a plurality of steps from top to bottom, and the diameters of the openings are gradually reduced from top to bottom. The opening diameter of the water inlet 5 of the flexible joint part is gradually reduced by 3 levels of steps.

The working principle is as follows: the water inlet 2 is arranged at the bulge of the front half part of the toothbrush main body part, the water outlet 4 is arranged at the rear half part of the toothbrush handle 3, a pipeline connecting the water inlet 2 and the water outlet 4 is arranged in the toothbrush main body part, and an angle of 30 degrees is formed between the direction of the water outlet 4 and the axial cross section of the toothbrush handle 3, so that the water flow sprayed out from the position is more convenient for a user to suck. The direction of the water inlet 2 is at an angle of 45 deg. to the axial cross-section of the handle 3, which facilitates insertion of the flexible joint 8. The flexible joint portion water inlet 5 is located at the center of the flexible joint portion 8, the flexible joint portion water inlet 5 is composed of a circular flexible joint portion skirt edge 6 and is outwards expanded to the edge in a concave step mode, namely, an opening of the flexible joint portion water inlet 5 is distributed in a plurality of step shapes from top to bottom, the diameter of the opening is gradually reduced from top to bottom, and therefore the flexible joint portion 8 made of rubber materials can be conveniently connected with water faucets of different diameters in a tight mode. The connecting pipe 7 forms an angle of 45 degrees with the end surface of the water inlet of the flexible joint part 8 and is communicated with the water inlet 5 of the flexible joint part. The connecting pipe 7 of the flexible combining part 8 extends into the water pipe of the water inlet 2 of the toothbrush main body part, and is contacted with the inner wall of the water pipe through the outside of the connecting pipe 7, and the lower end of the flexible combining part 8 is contacted with the outer surface of the front half part of the toothbrush main body part to form position restraint.

During operation, insert the mouth of a river 2 of selecting to connecting pipe 7 of flexible joint portion 8, hold toothbrush handle 3 and support tap with flexible joint portion shirt rim 6, tap of different diameters size can closely combine with the flexible joint portion shirt rim 6 of the flexible joint portion water inlet 5 of different diameters, because rivers enter into a less space suddenly, can produce certain pressure. Water flow with certain pressure enters from the water inlet 5 of the flexible joint part and enters the water inlet 2 through the connecting pipe 7, and in the water pipes of the water inlet 2 and the water outlet 4, the flow velocity and the water pressure of the water flow are improved due to the fact that the cross section area is continuously reduced, and finally, the slender water flow is sprayed out from the water outlet 4 and enters the water inlet.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
