[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The utility model relates to a water spray pipe which is used for being connected to a flushing system of a toilet. The water spray pipe comprises a pipe body 100.

[0028] like Figure 1 and Figure 2 As shown, the tube body 100 is an oblique straight tube, and the two ends of the tube body 100 are respectively a water inlet 110 and a water outlet 120. The water inlet 110 and the water outlet 120 can both be set to a circular mouth shape. The aperture of the water inlet 110 is larger than the aperture of the water outlet 120, that is, the water flow area of ​​the radial cross section of the water inlet 110 is larger than the water flow area of ​​the radial cross section of the water outlet 120. The tube body 100 extends obliquely, and the height of the water inlet 110 is higher than the water outlet 120, that is, the upper end of the tube body 100 in the figure is the water inlet 110, and the lower end is the water outlet 120. The inner diameter of the tube body 100 gradually decreases from the water inlet 110 to the water outlet 120, that is, the axial cross section of the tube body 100 is conical. In actual use, such as Figure 3 and Figure 4As shown, a water spray pipe is applied to a one-piece toilet. The water inlet 110 of the water spray pipe is connected to the water tank water valve 400 on the one-piece toilet, and the water outlet 120 is connected to the nozzle base nozzle 500 at the bottom of the one-piece toilet. The water tank water valve 400 and the nozzle base nozzle 500 are part of the flushing system. When the one-piece toilet needs to be flushed, the water tank water valve 400 is opened, and the water in the water tank enters the pipe body 100 from the water inlet 110, and the water flows along the pipe body 100 to the water outlet 120, and the water is sprayed from the water outlet 120 to the nozzle at the bottom of the one-piece toilet for flushing. The water inlet 110 and the water outlet 120 have a height difference, and the gravitational potential energy of the water is converted into dynamic potential energy. The water volume of the water tank to the water inlet 110 is certain. Since the water flow area of ​​the water inlet 110 is larger than the water flow area of ​​the water outlet 120, the pipe body 100 gradually shrinks toward the water outlet 120, and the instantaneous speed of water flowing in the pipe body 100 gradually increases. When it reaches the water outlet 120, the speed is the largest, thereby having a strong flushing force on the nozzle of the one-piece toilet. The longer the length of the pipe body 100, the longer the distance the water flows. Under the same height difference, the potential energy of the water flow will decrease due to the excessive length. After connection, the length of the pipe body 100 is the shortest connection distance between the water tank water valve 400 and the nozzle base nozzle 500, ensuring the minimum loss of water flow potential energy.

[0029] The diameter of the water inlet 110 is preferably set to a radius of not less than 36.5 mm, and the diameter of the water outlet 120 is preferably set to a radius in the range of 22.5 mm to 27.5 mm. The length of the rubber tube is preferably set in the range of 255 mm to 286 mm.

[0030] In some specific embodiments of the present invention, Figure 2As shown, a virtual oblique straight line 200 is formed in space between the center point of the water inlet 110 and the center point of the water outlet 120. In the figure, the center point of the water inlet 110 is the center of the radial section of the water inlet 110, and the center point of the water outlet 120 is the center of the radial section of the initial port. The virtual connection of the two center points in space is a virtual oblique straight line 200. The pipe body 100 extends in the direction of the virtual oblique straight line 200. Among them, the virtual oblique straight line 200 is inclined to the horizontal plane of the space. Among them, the water inlet 110 is vertically arranged, and the water outlet 120 is horizontally arranged. The upper end of the pipe body 100 extends a small section of the pipe vertically upward to form the water inlet 110, and the lower end of the pipe body 100 extends a small section of the pipe horizontally to form the water outlet 120. The water inlet 110 is vertically connected to the water tank water valve 400, and the water outlet 120 is horizontally connected to the nozzle base nozzle 500 at the bottom of the one-piece toilet. Among them, preferably, the angle between the virtual inclined straight line 200 and the horizontal plane of the space is in the range of 20° to 30° (including 20° and 30°), preferably 25°, that is, the inclination angle of the tube body 100 compared to the horizontal plane is set to be in the range of 20° to 30° (including 20° and 30°), preferably 25°.

[0031] In some specific embodiments of the present invention, the tube body 100 includes a vertical portion 130, an inclined portion 140 and a horizontal portion 150 connected in sequence. Figure 2As shown, it is represented by a vertical cross section of the tube body 100. The vertical portion 130 is located at the top of the tube body 100, and the vertical portion 130 extends in the vertical direction, and the vertical portion 130 constitutes the water inlet 110. The horizontal portion 150 is located at the bottom of the tube body 100, and the horizontal portion 150 extends in the horizontal direction to constitute the water outlet 120. The inclined portion 140 is located between the vertical portion 130 and the horizontal portion 150. The upper side of the inclined portion 140 is an inclined straight line extension, and the upper side of the inclined portion 140 can extend parallel to the virtual inclined straight line 200. The lower side of the inclined portion 140 includes an arc segment 141 and an oblique straight segment 142, and the arc segment 141 is closer to the vertical portion 130 than the oblique straight segment 142. The upper end of the arc segment 141 extends downward from the lower end of the vertical portion 130, and extends in an arc shape in the direction of the horizontal segment. The upper end of the arc segment 141 is tangent to the vertical portion 130. The oblique straight segment 142 is connected between the arc segment 141 and the horizontal portion 150. The oblique straight segment 142 is tangent to the arc segment 141, and the oblique straight segment 142 extends in an inclined straight line. When in use, water enters from the vertical portion, and the water falls vertically according to its own gravity, and the vertical portion 130 will not block the water in the vertical direction. The water flows downward and enters the inclined portion 140. The water impacts the arc segment 141, and the setting of the arc segment 141 can make the water change direction smoothly from the vertical portion 130 to the oblique straight segment 142, reducing the resistance to the water. After entering the oblique straight segment 142, the water flows in a straight line, and the inclined portion 140 fully converts the gravitational potential energy of the water into dynamic potential energy, thereby ensuring the impact of the water when it rushes out of the horizontal portion 150.

[0032] In some embodiments of the utility model, steps 101 are provided on the inner walls of the water inlet 110 and the water outlet 120. During installation, the port of the water valve 400 is inserted into the water inlet 110, and the port of the water valve 400 can abut against the step 101 of the water inlet 110, thereby limiting the installation depth of the port of the water valve 400 relative to the water inlet 110. The nozzle base nozzle 500 is inserted into the water outlet 120, and the end of the nozzle base nozzle 500 can abut against the step 101 of the water outlet 120, thereby limiting the installation depth of the nozzle base nozzle 500 relative to the water outlet 120. The step 101 is used to facilitate the installation and positioning of the water spray pipe. Among them, the inner diameter of the port of the nozzle base nozzle 500 is close to the inner diameter at the step 101 of the water outlet 120, so as to avoid the difference between the inner diameters of the two being too large, which causes the water in the nozzle to flow back to the water outlet 120.

[0033] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the outer walls of the water inlet 110 and the water outlet 120 are provided with mounting grooves 102 along the circumferential direction. Each mounting groove 102 is opened around the water inlet 110 and the water outlet 120 respectively. A clamp 300 is sleeved on the mounting groove 102. During installation, the port of the water valve 400 is inserted into the water inlet 110, and then the ports of the water inlet 110 and the water valve 400 are tightened and fixed to each other by locking the clamp 300 on the water inlet 110. The nozzle base nozzle 500 is inserted into the water outlet 120, and then the water outlet 120 and the nozzle base nozzle 500 are tightened and fixed to each other by locking the clamp 300 on the water outlet 120. The clamp 300 can be limited on the water inlet 110 and the water outlet 120 through the mounting groove 102. Before the water spray pipe is packaged and shipped out of the factory, the clamp 300 can be pre-installed on the water inlet 110 and the water outlet 120.

[0034] Further, such as Figure 1 and Figure 2 As shown, the inner walls of the water inlet 110 and the water outlet 120 are provided with ribs 103 along the circumferential direction. The ribs 103 on the water inlet 110 are opposite to the mounting groove 102, and the ribs 103 on the water outlet 120 are opposite to the mounting groove 102. When the clamp 300 on the water inlet 110 is tightened, the ribs 103 on the water inlet 110 can be closely attached to the port of the water valve 400, further sealing the water inlet 110 and the port of the water valve 400 to avoid leakage. When the clamp 300 on the water outlet 120 is tightened, the ribs 103 on the water outlet 120 can be closely attached to the nozzle base nozzle 500, further sealing the water outlet 120 and the water spray base nozzle to avoid leakage.

[0035] Preferably, the tube body 100 is a rubber tube. The tube body 100 is made of rubber material and has a certain elastic deformation ability, which can better adapt to the size difference between the water valve 400 and the nozzle base nozzle 500.
