DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0022] Reference Figs. 1-2 A flush-down type toilet, comprising a bedpan body 100 and a water tank (not shown in the figure), the top of the bedpan body 100 is provided with a water inlet channel 200, one end of the water inlet channel 200 is communicated with the water tank through a water inlet hole 210, the other end is communicated with a toilet bowl 110 of the bedpan body 100 through a flushing hole, the bottom of the toilet bowl 110 has a sewage inlet 120, the bedpan body 100 is provided with a sewage discharge pipeline communicated with the sewage inlet 120, the sewage discharge pipeline is sequentially divided into a lower sliding section 410, a rising section 420 and a falling section 430 along the water flow direction, the upper end of the lower sliding section 410 is communicated with the toilet bowl 110 through the sewage inlet 120, the lower sliding section 410 is inclined backward from top to bottom, the rising section 420 is located in front of the lower sliding section 410, the rising section 420 is inclined forward from bottom to top, the falling section 430 is vertically arranged, and the end of the falling section 430 is a sewage outlet 431.

[0023] The downward sliding section 410 is inclined downward to the rear, and the dirt can slide into the bottom along the pipe wall. The design of the inclined pipe can effectively utilize the gravity effect, thereby increasing the speed and impact force of the water flow. This design not only improves the sewage discharge efficiency, but also reduces the residence time of the dirt in the pipe and the possibility of blockage. Compared with the approximately vertically downward sewage inlet section in the prior art, the inclination angle of the downward sliding section 410 of the present application is larger, and the inclined pipe utilizes the gravity effect to form a certain flow rate of the sewage in the pipe, thereby more effectively flushing out the dirt. The vertical pipe mainly relies on the conversion of the gravitational potential energy of water into kinetic energy to push the sewage to flow downward. The design of the inclined pipe can reduce the energy loss of the water flow in the pipe and improve the sewage discharge efficiency. In addition, the inclined design of the downward sliding section 410 rebounds the splashed sewage back into the pipe, avoids the splashing of sewage during use, realizes the anti-splashing function, and is more visually beautiful.

[0024] In some embodiments of the present application, a spray hole 510 is provided on the sewage pipe, the spray hole 510 is located at the bottom of the junction of the downward sliding section 410 and the upward section 420, the toilet body 100 is provided with a spray water channel 500, the spray water channel 500 is located at the rear side of the sewage pipe as a whole, the upper end of the spray water channel 500 is in communication with the water inlet channel 200, the lower end is in communication with the spray hole 510, and the water outlet direction of the spray hole 510 is towards the upward section 420. During use, the water flow enters the toilet body 100 through the water inlet hole 210, most of the water flow flows to the flushing hole through the water inlet channel 200, and after washing the inner wall of the toilet bowl 110, it is discharged through the sewage pipe, and the remaining small amount of water flow is sprayed from the spray hole 510 through the spray water channel 500, and the high-pressure water flow directly impacts the dirt, and then merges with the main water flow and is discharged. The spray water channel 500 of the existing toilet flusher extends from the middle water inlet channel 200 to the front of the sewage pipe on one side, the spray water channel 500 is long and has a large diameter, and the water flow is easy to cause energy loss during spraying, which affects the spraying effect, and at the same time, the large water channel also leads to an increase in manufacturing cost. Unlike the spray water channel 500 in the prior art which extends from the side to the front of the sewage pipe, the spray water channel 500 of the present application is located at the rear of the middle part of the toilet flusher and directly extends to the bottom of the sewage pipe, which shortens the water flow path and reduces the energy loss caused by friction resistance when the water flow flows in the pipe. In addition, the inclination angle of the spray water channel 500 is larger, so that the water flow speed is faster and the impact force is stronger, thereby further improving the anti-clogging function.

[0025] In some embodiments of the present application, the cross-sectional diameter θ of the jet water channel 500 is 12±4mm. The jet water channel 500 of the present application is designed to be elongated, with a small diameter, which reduces the cross-sectional area of the water flow. In order to maintain the same flow rate, the water flow must pass through the pipe at a faster speed. Therefore, under the same conditions, the water flow speed will be faster. The fast water flow can form a strong water flow pressure in a short time, thereby more effectively flushing the dirt. In addition, the higher water flow speed can also reduce the residence time of the water flow in the pipe, reducing the risk of blockage.

[0026] In some embodiments of the present application, the pipe diameter of the rising section 420 is smaller than that of the descending section 410 and the falling section 430. The overall layout of the sewage pipe is from large to small to large. This design is mainly to optimize the sewage efficiency and reduce the risk of blockage. The descending section 410 with a larger pipe diameter can accommodate more dirt and wastewater, ensuring rapid discharge. The rising section 420 with a smaller pipe diameter utilizes the increase in water flow speed to improve the flushing effect. Finally, the vertical large-diameter falling section 430 ensures smooth discharge of sewage, avoiding blockage, thereby achieving the anti-clogging function.

[0027] In some embodiments of the present application, the inclination angle α of the descending section 410 relative to the horizontal plane is 50°-60°. The inclination angle of 50°-60° of the descending section 410 can form a higher flow rate.

[0028] According to some embodiments of the present application, the inclination angle of the rising section 420 and the descending section 410 is the same. The rising section 420 is next to the descending section 410 and shares a section of pipe wall with the descending section 410.

[0029] In some embodiments of the present application, the flushing hole includes a first flushing hole 310 and a second flushing hole 320. The first flushing hole 310 is arranged at the top of the side wall of the toilet bowl 110, and the second flushing hole 320 is arranged at the top of the rear wall of the toilet bowl 110. The water outlet direction of the second flushing hole 320 is downward. The first flushing hole 310 is used to flush the side wall of the toilet bowl 110, and the second flushing hole 320 is used to flush the rear wall of the toilet bowl 110.

[0030] In some embodiments of the present application, the water inlet channel 200 includes a main water channel 220 and two branch water channels 230. The main water channel 220 is located behind the toilet bowl 110, the upper end of the jet water channel 500 is communicated with the main water channel 220, the water inlet hole 210 is located in the main water channel 220, and the two branch water channels 230 are located at the top of the rear wall of the toilet bowl 110. The flushing hole has two, which are respectively located at the top of the two side walls of the toilet bowl 110. Each side flushing hole is communicated with the main water channel 220 through a branch water channel 230, and the second flushing hole 320 is communicated with the branch water channel 230. The water in the water tank reaches the main water channel 220 through the water inlet hole 210, and is sprayed out from the two first flushing holes 310 on the two sides through the two branch water channels 230.

[0031] In some embodiments of the utility model, second flush hole 320 has several, along the back wall of the bowl 110 transverse arrangement. Set up several second flush hole 320 can increase the flushing area of the back wall of the bowl 110.

[0032] Although the embodiments of the utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
