DETAILED DESCRIPTION
[0028] Embodiments of the present application are described below in detail with reference to the accompanying drawings, in which like reference numerals refer to like elements throughout. The embodiments described below are examples of the present application, and are intended to explain the present application, and should not be understood as limiting the present application.
[0029] The present application relates to a toilet bowl, comprising a main body 100.
[0030] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the main body 100 is provided with a water jet 200, a flow guide surface 300, a cleaning surface 400 and a gall bladder tip 500. The flow guide surface 300, the cleaning surface 400 and the gall bladder tip 500 are connected in sequence from top to bottom, and the flow guide surface 300, the cleaning surface 400 and the gall bladder tip 500 constitute part of the gall bladder cavity of the main body 100. The cleaning surface 400 is an annular surface, which forms a cavity with both upper and lower ends open and a funnel shape from top to bottom. The gall bladder tip 500 is connected to the lower end of the cleaning surface 400, and the gall bladder tip 500 is used to gather and temporarily store excrement and connect a sewage pipeline 700. The flow guide surface 300 extends circumferentially along the upper end of the cleaning surface 400, and the flow guide surface 300 is arranged downwardly from the outside to the inside, and it should be noted that the outside of the flow guide surface 300 is the side away from the cleaning surface 400, and the inside of the flow guide surface 300 is connected to the upper end of the cleaning surface 400. The cleaning surface 400 is arranged downwardly from the outside to the inside, the cavity surrounded by the cleaning surface 400 gradually decreases from top to bottom, and the inclination angle of the cleaning surface 400 is greater than that of the flow guide surface 300. In the direction shown in the figure, the cleaning surface 400 includes a first flushing surface 410 and a second flushing surface 420 distributed on the left and right. It should be noted that "left and right" here is a relative position, which can be that the first flushing surface 410 is on the left and the second flushing surface 420 is on the right, or that the first flushing surface 410 is on the right and the second flushing surface 420 is on the left. In this embodiment, from the top view, the first flushing surface 410 is arranged on the left side and the second flushing surface 420 is arranged on the right side. The front side of the first flushing surface 410 and the front side of the second flushing surface 420 are connected, and the rear side of the first flushing surface 410 and the rear side of the second flushing surface 420 are connected, and the front side region of the first flushing surface 410 is provided with a downwardly recessed recess 411, and the recess 411 can be a concave shape with a certain circular arc. The front side region of the second flushing surface 420 is provided with an upwardly protruding protrusion 421, and the protrusion 421 can be a convex shape with a certain circular arc. The water jet 200 is arranged above the rear of the flow guide surface 300 on the side where the first flushing surface 400 is located, that is, in the direction shown in the figure, the water jet 200 is arranged at a rear position on the upper part of the main body 100, the water jet 200 is located on the upper left side of the rear of the flow guide surface 300, and the emission direction of the water jet 200 is tangential to the flow guide surface 300.
[0031] In actual use, the water jet 200 is connected to the water tank of the toilet or an external water supply system. Water is injected into the gall bladder cavity of the main body 100 through the water jet 200, and the water jet 200 is arranged on the left side of the flow guide surface 300, and the water jet 200 is arranged on the left side of the flow guide surface 300. Figure 5As shown, in the direction of the illustration, water flows along the guide surface 300 counterclockwise, when the water flows along the guide surface 300 counterclockwise for a circle, due to the guide surface 300 having a certain angle, a part of the water will flow along the guide surface 300 downward to the washing surface 400 to brush the whole washing surface 400. A larger part of the water will continue to flow into the first flushing surface 410 according to the dynamic potential energy and the gravitational potential energy after rotating counterclockwise for a circle along the guide surface 300, the water continues to flow counterclockwise on the first flushing surface 410, when the water flows to the concave part 411, the water is gathered by the concave part 411, which hinders the water from flowing over the concave part 411 to continue to flow counterclockwise to the second flushing surface 420, most of the water flows downward to the gallbladder tip 500 along the concave part 411, which greatly increases the impact force of the water on the gallbladder tip 500, so that the excrement in the gallbladder tip 500 is flushed out to the sewage pipeline 700. A small part of the water will continue to flow counterclockwise to the second flushing surface 420 after flowing counterclockwise over the concave part 411, this part of the water flows to the convex part 421 and then flows downward under the blocking effect of the convex part 421, further washing the gallbladder tip 500. The cooperation of the concave part 411 and the convex part 421 makes the water flow form a strong flushing force and gather on the front side of the washing surface 400, flushing the excrement in the gallbladder tip 500 to the sewage pipeline 700. Under the effect of the water gathering effect of the concave part 411, the dynamic potential energy of the water flowing to the convex part 421 is greatly weakened, avoiding the water flowing to the convex part 421 from tangentially colliding with the convex surface of the convex part 421 to flow to the rear side of the washing surface 400 due to the excessive dynamic potential energy.
[0032] wherein, as Figure 3As shown, in the top view, the lowest point of the recess 411 is located to the left of the center line 101, that is, the lowest point of the recess 411 is not at the center line 101. The center of the gallbladder tip 500 in the left-right direction is located at the center line 101, that is, the gallbladder tip 500 is centrally arranged in the left-right direction of the gallbladder cavity of the main body 100, and the drain pipe 700 extends rearward in a U shape from the lower end of the gallbladder tip 500, and the drain pipe 700 is also located at the center in the left-right direction of the main body 100. It can be that the distance between the lowest point of the recess 411 and the center line 101 in the left-right direction is in the range of 25mm to 45mm. The right side of the recess 411 is smoothly connected to the left side of the second flushing surface 420, and the two can be tangentially connected, and the second flushing surface 420 is smoothly connected between the right side of the first flushing surface 410 and the left side of the convex portion 421. After the water flow flows counterclockwise to the recess 411, a rotation position is formed at the recess 411, and after the water flow flows forward to the lowest point of the recess 411, it will flow counterclockwise to the right rear. When most of the water flow flows near the center line 101, the kinetic energy of the counterclockwise flow is weakened the most, so that the water can effectively accumulate on the side of the recess 411 close to the center line 101 and flow downward to impact the gallbladder tip 500. After part of the water flow passes through the first flushing surface 410 into the second flushing surface 420 and impacts the convex portion 421, the water flow will not be hindered. Further, in the top view, the distance L1 between the lowest point of the recess 411 and the center line 101 is less than the distance L2 between the highest point of the convex portion 421 and the center line 101, where the distance is the distance in the left-right direction. The convex portion 421 is farther away from the center line 101 than the recess 411, effectively reducing the kinetic potential of a small part of the water that rushes to the convex portion 421 from the recess 411, and avoiding water splashing when the water flows along the convex portion 421 to the back of the main body 100.
[0033] In an embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the flow guide surface 300 includes a first flow guide section 310 and a second flow guide section 320 distributed left and right, the front side of the first flow guide section 310 and the front side of the second flow guide section 320 are connected, and the rear side of the first flow guide section 310 and the rear side of the second flow guide section 320 are connected. The upper side of the first flushing surface 410 is connected to the lower side of the first flow guide section 310, and the upper side of the second flushing surface 420 is connected to the lower side of the second flow guide section 320. From the top view of the main body 100, the front part of the first flow guide section 310 has a first area 311 with a width gradually decreasing from back to front and then increasing, and the first area 311 is opposite to the recess 411 in the up-down direction. The front part of the second flow guide section 320 has a second area 321 with a width gradually increasing from front to back and then decreasing, and the second area 321 is opposite to the convex 421 in the up-down direction. The water outlet 200 is located above the rear side of the first flow guide section 310, and the water sprayed from the water outlet 200 is tangent to the first flow guide section 310 in front. The water flows counterclockwise along the first flow guide section 310 and the second flow guide section 320, and part of the water directly flows downward from the first flow guide section 310 and the second flow guide section 320 to the first flushing surface 410 and the second flushing surface 420, respectively. After the water flowing counterclockwise flows to the rear part of the second flow guide section 320, it enters the first flushing surface 410 and continues to flow counterclockwise. When the water flows along the first flow guide section 310, part of the water flows into the recess 411 downward when it flows to the first area 311, and the water gathered through the recess 411 pre-flushes the gallbladder tip 500. Part of the water continues to flow into the second flow guide section 320, and the second area 321 provides a large area for the water to flow to the rear side, ensuring that the water flowing from the rear side of the second flow guide section 320 into the first flushing surface 410 still has enough power to flow to the front side to gather in the recess 411. Among them, the minimum width of the first area 311 is opposite to the lowest point of the recess 411 in the up-down direction, and the water flows quickly to the recess 411 for pre-flushing when it flows through the narrowest part of the first area 311. The maximum width of the second area 321 is opposite to the highest point of the convex 421 in the up-down direction, reducing the amount of water flowing downward along the convex 421 from the widest part of the second area 321.
[0034] In an embodiment, as shown in Figure 1 、 Figure 2 and Figure 4 , the top of the gallbladder cavity of the main body 100 has a surrounding wall 110 arranged along the outer periphery of the flow guide surface 300, and the upper part of the surrounding wall 110 is provided with a convex edge 120 extending towards the inside of the gallbladder cavity of the main body 100. When the water flows along the flow guide surface 300, the surrounding wall 110 and the convex edge 120 block the water flow from spraying out of the main body 100.
[0035] In an embodiment, as shown in Figure 3 and Figure 5As shown, the main body 100 is also equipped with a water supply path 600. The water supply path 600 includes an inlet channel 610, a first branch channel 620, and a second branch channel 630. The first branch channel 620 and the second branch channel 630 are connected in parallel to the downstream end of the inlet channel 610. The first branch channel 620 and the second branch channel 630 are distributed on the left and right sides and are at the same height. A spray nozzle 200 is provided at the end of the first branch channel 620, and the end of the second branch channel 630 is closed. The inlet channel 610 is connected to a water tank or other water supply system. After the water initially enters the inlet channel 610, it will be diverted to the first branch channel 620 and the second branch channel 630, thereby reducing the initial spray volume of the spray nozzle 200, reducing the initial spray impact force, and avoiding water splashing due to turbulence and excessive impact force when the water initially sprays out of the spray nozzle 200. After the water flows into the second channel 630, it gradually fills the second channel 630. After filling, the subsequent water mainly flows into the first channel 620, at which point the water flow tends to be stable. After the water supply to the inlet channel 610 is stopped, the water in the second channel 630 will be discharged from the first channel 620, and the water seal of the chamber can also be replenished.
[0036] Furthermore, the water supply channel 600 is provided with an arc-shaped wall 640, which is shared by the first branch channel 620 and the second branch channel 630. The exit direction of the inlet channel 610 is perpendicular to the arc-shaped wall 640. After the initial water flow impacts the arc-shaped surface from the inlet channel 610, it can be relatively evenly distributed to the first branch channel 620 and the second branch channel 630. The cross-sectional area of the first branch channel 620 and the second branch channel 630 gradually increases from the upstream side to the downstream side, and the upstream side of the first branch channel 620 and the second branch channel 630 is the side close to the inlet channel 610. When the water pressure is low, the gradually increasing cross-sectional area of the first branch channel 620 ensures that the water flow has sufficient kinetic energy when it is ejected from the nozzle 200. As the water gradually fills the second channel 630 and before the water inlet channel 610 stops supplying water, the cross-sectional area of the second channel 630 gradually increases, which can reduce the amount of water flowing back from the second channel 630 to the first channel 620.
[0037] In one embodiment, such as Figure 2As shown, the main body 100 further comprises a drain pipe 700, the rear side of the washing surface 400 extends out of the partition layer 130 towards the gallbladder tip 500, and the gallbladder tip 500 is located at the lower front side of the partition layer 130. The drain pipe 700 comprises an inlet section 710, a sinking section 720, a rising section 730 and a discharge section 740 which are sequentially communicated, the inlet section 710, the sinking section 720 and the rising section 730 are sequentially distributed in a U shape along the partition layer 130, forming a U-shaped pipe structure, so as to form a water seal at the gallbladder tip. The inlet section 710 is connected with the gallbladder tip 500, the lower side wall of the discharge section 740 extends downwardly from the joint with the rear side wall of the discharge section 740, the joint between the lower side wall of the discharge section 740 and the rear side wall of the discharge section 740 is in the shape of a crescent with the notch downward, so that the opening at the joint between the rising section 730 and the discharge section 740 is larger, the drainage is smoother, and the backflow phenomenon is effectively prevented.
