Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Fig. 1 and Fig. 2, the utility model provides a double-flush toilet, which includes a toilet body 1, a sewage outlet 2, a drainage pipe 5 and a drainage mechanism; 5 is connected; Drain mechanism comprises drainage ring 6, and drainage ring 6 is located at toilet body 1 top, and drainage ring 6 is the passage of flushing water, and during flushing, flushing water enters drainage ring from water tank, enters toilet body again, realizes toilet flushing. At least one main flushing hole 7 and at least one auxiliary flushing hole 8 are arranged on the drainage ring 6, and the main flushing hole 7 and the auxiliary flushing hole 8 are all along the substantially horizontal direction of the inner peripheral surface of the drainage ring Spray flushing water; between the main flushing water hole 7 and the drain ring 6, a water guide arc surface 9 is also provided, and the area of the water guide arc surface 9 gradually becomes larger along the spraying direction of the flush water, so as to realize the flushing water The purpose of guiding the flow from the drain circle to the toilet body and forming a swirl flow. The main flushing water hole 7, the drainage ring 6 and the water guide arc surface 9 constitute the first heavy flushing structure, and the auxiliary flushing water hole 8 and the drainage ring 6 constitute the second heavy flushing structure. When flushing is required, press the flushing button, and the flushing water flows to the main flushing water hole 7 and the auxiliary flushing water hole 8 through the drainage ring, and more flushing water flows out from the main flushing water hole with a larger aperture , it passes through the diversion of the water-guiding arc surface, and quickly flows to the surface of the toilet body in the form of a vortex to flush it; while the auxiliary flushing hole with a smaller aperture flows out less flushing water, and the flushing water flows along the drainage circle. Flowing, effectively cleaning the drainage ring, and at the same time, after meeting the water guide arc surface, the water guides through the water guide arc surface, flows into the toilet body, and flushes the inner peripheral surface of the toilet body.

It should be noted that in the existing technology, a number of flushing holes and a corresponding number of water guide arcs are uniformly arranged on the toilet drainage ring. Small, it is easy to cause the flushing water to rush out along the tangential direction of the arc surface instead of flushing against the inner wall of the toilet, which weakens the flushing effect of the flushing water, and there is also a hidden danger of flushing water splashing.

In order to solve the above problems, the main flushing hole 8 is arranged at the rear of the drainage circle 6, correspondingly, the water guide arc surface 9 is also arranged at the rear of the drainage circle, and the four auxiliary flushing holes 8 are arranged in front of the drainage circle 6 When such a setting is adopted, the flushing water flushed out of the auxiliary flushing hole passes through the diversion of the drainage ring and flows to the water guiding arc surface 9 at the rear of the drainage ring, and together with the water flushed out of the main flushing hole, it forms a vortex The form enters the toilet body, and this setting plays the role of flushing the drainage circle, and at the same time, it will not cause the problem of splashing water. As a preferred embodiment, the drain ring hangs toward the inside of the toilet body 1 to form a splash-proof edge 10, which further ensures the effect of the toilet against splashing water.

As a kind of preferred embodiment, with reference to Fig. 2, be provided with two main flush water holes 8 on the drain ring 6 rear portion, the main flush water holes are shapes such as circle, square, ellipse; Its aperture is 8mm. Correspondingly, the water guide arc surface 9 is also arranged between the flushing hole at the rear of the drain ring and the drain ring. Four auxiliary flushing holes 8 are arranged on the front part of the drainage ring 6; the auxiliary flushing holes are circular, rectangular, oval and other shapes, and their apertures are 4 mm; as a preferred embodiment, the main flushing holes 7 and auxiliary flushing holes 8 are distributed in a clockwise direction, and the center line of auxiliary flushing holes 8 is at an angle of 45 degrees to the surface of drainage ring 6. When this setting is adopted, the flushing water can form a rotating vortex along the clockwise direction , and enter the toilet body through the diversion of the water diversion arc surface to achieve a better flushing effect.

As a preferred embodiment, referring to FIG. 1 , the drainage mechanism further includes a spray hole 12 .

Referring to Figures 1 and 3, the toilet body 1 is provided with a diversion concave surface. Such a design can make the flushing water from the flushing hole further concentrate on the diversion concave surface after forming a vortex, thereby improving the scrubbing power. Furthermore, the slopes of the water storage surface and the diversion concave surface are a, b, and a > b. This setting not only strengthens the concentration of the vortex water flow, but also reduces the water-air interaction when the sewage flow is siphoned. The contact area reduces the noise of flushing.

In the double-structure toilet of the present utility model, the sewage discharge mechanism includes a sewage discharge port 4 and a sewage discharge pipe 5, wherein a water seal is provided between the sewage discharge port 4 and the water storage surface 2, and the height of the water seal is 118mm. The higher water seal height can Effectively block odor. The sewage pipe 5 is S-shaped, which can enhance the siphon force and is more conducive to flushing. Further, the diameter of the sewage outlet 4 is 56 mm, and the pipe diameter of the sewage pipe 5 is 50 mm. The larger diameter enables the toilet to remove relatively large foreign objects while effectively preventing blockage. Further, in order to prevent clogging, a smooth glaze is provided on the inner wall of the sewage pipe.

The above-mentioned embodiment is not the only embodiment of a double-flush structure toilet of the present utility model, and any modifications made within the spirit and principles of the utility model, equivalent replacements and improvements, etc., shall be included in the utility model. within the scope of protection.
