In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0026] The present application proposes a toilet having a toilet bowl. A spray gun 1000 is installed on the toilet bowl, and the spray gun 1000 is arranged at the edge of the toilet bowl and can be controlled to extend into the toilet bowl and spray water to the user for flushing, so that the user can clean the toilet bowl during use.

[0027] See also Figure 1The spray gun 1000 includes a spray head 100, a mounting portion 200 and a driving portion 300. A water pipe 400 is provided on the mounting portion 200, and the water pipe 400 is connected to the spray head 100 and supplies water to the spray head 100. The driving portion 300 is fixedly mounted on the toilet, and the driving portion 300 is in transmission connection with the spray head 100, so that during use, the driving portion 300 can be controlled to drive the spray head 100 to extend or retract relative to the mounting portion 200. In some embodiments, in order to prevent the water pipe 400 from interfering with other structures during the movement of the spray head 100 relative to the mounting portion 200, the water pipe 400 can be a soft rubber tube. The water pipe 400 can be connected to a valve 50, and the valve 50 can be controlled and selectively supply water to or interrupt the water supply to the water pipe 400. In some embodiments, the spray gun 1000 can also include a control device (not shown), which is electrically connected to the valve 50 and the driving portion 300. The valve 50 and the driving unit 300 can respond to the control instructions of the control device and perform corresponding actions.

[0028] In some embodiments, please refer again to Figure 1 The spray gun 1000 may further include a jacket 600 , which may be a cylindrical jacket 600 having a ring-shaped cross-section. The spray head 100 may be disposed in the jacket 600 , and the driving portion 300 may drive the jacket 600 to move, thereby driving the spray head 100 to extend or retract relative to the mounting portion 200 .

[0029] See also Figure 2 The nozzle 100 includes a base 11, a first water inlet chamber 16, a first outlet chamber 17, a first water channel 20 and a second water channel 21. The first water channel 20 and the second water channel 21 are connected to the first water inlet chamber 16 and the first outlet chamber 17 at the same time. A first water inlet 14 is provided on the base 11, and the first water inlet chamber 16 is provided in the base 11 and is connected to the first water inlet 14. A first outlet hole 12 is also provided on the base 11, and the first outlet hole 12 is connected to the first outlet chamber 17. After the water flows into the first water inlet 14, it flows through the first water inlet chamber 16, and enters the first outlet chamber 17 through the first water channel 20 and the second water channel 21, and finally sprays out from the first outlet hole 12, so that the user can use the water spray for cleaning.

[0030] The base 11 may include a substrate 70, a bottom cover 90 and a top cover 80. The substrate 70 has a certain thickness and is provided with a first surface 71 and a second surface 72 opposite to each other. The bottom cover 90 is fixedly connected to the substrate 70. As an embodiment, the bottom cover 90 can be bonded and attached to the first surface 71 by waterproof glue, and the top cover 80 can be attached to the second surface 72 in the same manner. In some other embodiments, the substrate 70 may be provided with threaded holes 73, which are respectively provided on the first surface 71 and the second surface 72 and penetrate the first surface 71 and the second surface 72. The bottom cover 90 and the top cover 80 may also be provided with mounting holes opposite to the threaded holes 73. By inserting bolts 74 into the mounting holes and fixedly connecting them with the threaded holes 73, the top cover 80 and the bottom cover 90 may also be fixedly installed on the substrate 70. In some embodiments, a sealing strip 75 may be provided on the first surface 71 and the second surface 72, which can seal the top cover 80, the bottom cover 90 and the substrate 70. The substrate 70, the bottom cover 90 and the top cover 80 together form a substantially cylindrical base 11.

[0031] Please read again Figure 3 and Figure 4 The nozzle 100 also includes a spoiler 60 disposed in the first water inlet chamber 16. The spoiler 60 is used to disturb the water flow so that the disturbed water flow forms turbulence and then flows into the first water channel 20 and the second water channel 21. As an example, the spoiler 60 can be a protrusion on the inner wall of the first water inlet chamber 16. In some other embodiments, the spoiler 60 can also be a separate component assembled in the first water inlet chamber 16, which is not limited here. The spoiler 60 is located in the first water inlet chamber 16, which blocks the flow of water to a certain extent, and changes the flow direction of the water flow in the process of blocking. Since the water flow as a whole will continue to flow under the action of water pressure, after the water flow passes through the spoiler 60, the state of the water flow will become a turbulent state of irregular motion, and continue to flow into the first water channel 20 and the second water channel 21.

[0032] The side of the substrate 70 may be roughly arc-shaped. In some embodiments, when the jacket 600 is sleeved on the base 11, the jacket 600 may abut the arc surfaces on both sides of the substrate 70. The first water inlet 14 and the second water inlet 15 may be arranged on the end face of one end of the substrate 70, and configured as a pagoda-shaped interface 23, which is convenient for plugging with the water pipe 400. The first water inlet cavity 16 may be arranged on the first surface 71 and formed by penetrating the first surface 71. The first water inlet 14 is communicated with the first water inlet cavity 16. In some embodiments, the second water inlet cavity 19 is also arranged on the first surface 71 and formed by penetrating the first surface 71. The second water inlet 15 may be arranged on the same end face as the first water inlet 14, and the axis of the second water inlet 15 may be arranged roughly parallel to the axis of the first water inlet 14, so as to facilitate the connection of the water pipe 400. After the second water inlet 15 penetrates the substrate 70 from the end face of the substrate 70, it is communicated with the second water inlet cavity 19. The first outlet cavity 17 can be disposed on the second surface 72 and penetrate the second surface 72. The first water channel 20 is substantially the same as the second water channel 21 and is formed on the substrate 70. The first water channel 20 connects the first water inlet cavity 16 and the first outlet cavity 17, and the second water channel 21 also connects the first water inlet cavity 16 and the first outlet cavity 17. As an embodiment, please refer to Figure 4 , the first water inlet chamber 16 may include a flow stabilizing chamber 161 and a diverter chamber 162, the first water inlet 14 is connected to the flow stabilizing chamber 161, and the spoiler block 60 is arranged in the flow stabilizing chamber 161. The water flows into the diverter chamber 162 through the flow stabilizing chamber 161, and the diverter chamber 162 is connected to the first water channel 20 and the second water channel 21. The cross section of the diverter chamber 162 can be larger than the cross section of the flow stabilizing chamber 161, so that after the water flow is disturbed by the spoiler block 60 in the flow stabilizing chamber 161 and forms turbulence, the flow velocity is relatively slowed down when entering the diverter chamber 162. Since the water flow velocity is relatively slow and the state of the water flow is turbulent, the pressure of the water flow on the inner wall of the diverter chamber 162 in all directions is less affected by the inertia of the fluid itself when it flows, so that the pressure of the fluid relative to the inner wall of the diverter chamber 162 is roughly equal in all directions.

[0033] See also Figure 5 In some embodiments, the first water inlet chamber 16 may also have a bending angle of 90 degrees, so that when the water flows through the first water inlet chamber 16, the direction of the water flow changes at the bend of the first water inlet chamber 16, and turbulence may be formed to enter the diversion chamber 162. In this embodiment, the distances of the first water channel 20 and the second water channel 21 relative to the first water inlet chamber 16 may be substantially the same, so that when the water flowing through the first water inlet chamber 16 enters the diversion chamber 162, it can also enter the first water channel 20 and the second water channel 21 evenly.

[0034] See also Figure 6The first water channel 20 has a first outlet 201 connected to the first outlet cavity 17, and the second water channel 21 has a second outlet 211 connected to the first outlet cavity 17. As an embodiment, the first outlet 201 and the second outlet 211 can be arranged relative to each other, so that the water sprayed from the first outlet 201 can collide with the water sprayed from the second outlet 211, and sprayed from the first outlet hole 12 after the collision. The first outlet 201 and the second outlet 211 are located on both sides of the first outlet hole 12, so that the first outlet hole 12 is exactly located at the collision point between the water flow sprayed from the first outlet 201 and the water flow from the second outlet 211. The water flow after the collision is sprayed from the first outlet hole 12, and granular water splashes can be generated. The granular water splashes are less irritating to the user during the cleaning process and have a higher degree of comfort.

[0035] As an embodiment, the diameter A1 of the first water channel 20 and the diameter A2 of the second water channel 21 can be substantially the same. Since the diversion chamber 162 is connected to the first water channel 20 and the second water channel 21, the water will flow into the first water channel 20 and the second water channel 21 under the action of pressure. Since the first water channel 20 and the second water channel 21 have the same diameter, the flow rate of the water flowing into the first water channel 20 and the second water channel 21 is also the same. According to the fluid flow formula (Q) = average flow rate (v) × pipe cross-sectional area (A), since the water flow rates V1 and V2 in the first water channel 20 and the second water channel 21 are equal, the water flow rates flowing into the first water channel 20 and the second water channel 21 are also equal.

[0036] In some embodiments, the first water channel 20 and the second water channel 21 further include a first buffer chamber 202 and a second buffer chamber 212. The first buffer chamber 202 and the second buffer chamber 212 are disposed on the substrate 70, and the first water channel 20 is connected to the first outlet chamber 17 through the first buffer chamber 202, and the second water channel 21 is connected to the first outlet chamber 17 through the second buffer chamber 212. The first outlet 201 can connect the first buffer chamber 202 and the first outlet chamber 17, and the second outlet 211 can connect the second buffer chamber 212 and the first outlet chamber 17. The cross-sectional diameters of the first buffer chamber 202 and the second buffer chamber 212 can be larger than those of the first water channel 20 and the second water channel 21, so that the water flowing through the first water channel 20 and the second water channel 21 can have a relatively slow flow rate when flowing through the first buffer chamber 202 and the second buffer chamber 212. In this way, when the water flows through the first outlet 201 and the second outlet 211 and flows into the first outlet cavity 17 , it can be more evenly impacted, and the water flow ejected from the first outlet hole 12 can be prevented from being skewed.

[0037] See also Figure 7, the first exit cavity 17 has an exit surface 171 opposite to the first exit hole 12. As an embodiment, the exit surface 171 can be roughly arc-shaped. After the water flow collides in the first exit cavity 17, since the exit surface 171 is opposite to the first exit hole 12, when the water flow in the first exit cavity 17 collides with the exit surface 171, the exit surface 171 can make the water flow that collides with the exit surface 171 be ejected along an angle that is roughly diffused relative to the axial direction of the first exit hole 12. In this way, when the water flow is ejected from the first exit hole 12, it can be diffused relative to the axial direction of the first exit hole 12, so that the water flow ejected from the first exit hole 12 can be ejected roughly along a fan shape, thereby increasing the cleaning area.

[0038] Please refer again Figure 3 and Figure 4 , the bottom cover 90 is used to close the first water inlet chamber 16. The bottom cover 90 may have a first fitting plane 91, and when the first fitting plane 91 fits with the first surface 71, the first water inlet chamber 16 can be closed. In some embodiments, the bottom cover 90 can also close the second water inlet chamber 19 at the same time. The first fitting plane 91 can also abut against the sealing strip 75 on the first surface 71, so that the bottom cover 90 can seal the first water inlet chamber 16 and the second water inlet chamber 19 more tightly. In some embodiments, an assembly portion 91 can be provided on the bottom cover 90 away from the first surface 71, and the assembly portion can be used to connect with the driving portion 300, so that the driving portion 300 can realize the movement of the driving nozzle 100 by driving the bottom cover 90. In other embodiments, the assembly portion of the bottom cover 90 can abut against the inner side of the outer jacket 600, and the driving portion 300 can be connected to the outer jacket 600, so that the driving portion 300 drives the base 11 to move through the outer jacket 600, and then can also realize the function of driving the nozzle 100 to move.

[0039] The top cover 80 may have a second fitting plane 81, and the second fitting plane 81 fits with the second surface 72, so that the top cover 80 closes the first outlet cavity 17 located on the substrate 70. The first outlet hole 12 is arranged on the side of the top cover 80 away from the second fitting plane 81. As an embodiment, the first outlet hole 12 may be circular, with a diameter of about 1.5mm to 2.5mm and a depth of about 0.50 to 1.20mm. In this way, the water flow flowing into the first outlet cavity 17 from the first outlet 201 and the second outlet 211, after collision, when the water flow sprayed from the first outlet hole 12 contacts the user, the force is more comfortable, and also has a corresponding cleaning effect. The axis of the first outlet hole 12 may have a certain angle C with the second surface 72. In this embodiment, the angle C formed by the axis and the second surface 72 is an acute angle. In this way, when the water flow is sprayed from the first outlet hole 12, the direction of the water flow has a certain angle with the direction of the spray gun 1000, which is convenient for the user to clean when using it. By adjusting the angle between the outlet and the second surface 72, the angle of the water flow when it is sprayed can be adjusted. According to the needs of the user, the angle can be adjusted to select the best cleaning angle. In some other embodiments, the first outlet hole 12 can also have a mesh structure that can disperse the water flow. Since the water flow has a certain water pressure, the water flow can pass through the mesh structure under the action of pressure and spray out from the first outlet hole 12, which can also achieve the effect of diffusing the water flow and increasing the cleaning area.

[0040] The working principle of the toilet provided in this embodiment is as follows:

[0041] When the user needs to use it, by operating the control device, the driving unit 300 responds to the control device and drives the nozzle 100 to extend along the chute. When the nozzle 100 extends to the specified position, the corresponding valve 50 responds to the control device and causes the water pipe 400 to start supplying water. The water flows into the steady flow chamber 161 from the first water inlet 14. When flowing through the spoiler block 60 in the steady flow chamber 161, the flow state of the water flow is disturbed and turbulence is formed. After passing through the steady flow chamber 161, the water flows into the diversion chamber 162, and evenly enters the first water channel 20 and the second water channel 21 in the diversion chamber 162. The water flow in the first water channel 20 flows into the first outlet chamber 17 from the first outlet 201, and the water flow in the second water channel 21 flows into the second outlet chamber 18 from the second outlet 211. Since the first outlet 201 is opposite to the second outlet 211, the two streams of water collide in the first outlet chamber 17. During the collision, since the first exit hole 12 is arranged between the first outlet 201 and the second outlet 211, and the first exit cavity 17 is provided with an exit surface 171 with a semicircular cross section relative to the first exit hole 12, the water flow diffuses along the fan shape to the outside of the first exit hole 12 under the reflection of the semicircular exit surface 171, and is ejected in the form of particles, thereby achieving the function of cleaning the user's private parts. The granular water flow has the characteristics of less irritation and higher comfort. At the same time, since the water flow diffuses along the fan shape, the water flow can clean a larger area, which is convenient for effectively cleaning the female private parts.

[0042] The above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various implementation modes of the present application, and should all be included in the protection scope of the present application.
