The water pipe 400 may be connected to the valve 50, and the valve 50 may controllably and selectively supply water into the water pipe 400 or interrupt the supply of water. In some embodiments, the spray gun 1000 may further include a control device (not shown) electrically connected to the valve 50 and the driving part 300. The valve 50 and the driving unit 300 can perform corresponding operations in response to a control command from the control device.

In some embodiments, referring to fig. 1 again, the spray gun 1000 may further include an outer sleeve 600, the outer sleeve 600 may be a cylindrical outer sleeve 600 with an annular cross section, the spray head 100 may be disposed in the outer sleeve 600, and the driving portion 300 may drive the outer sleeve 600 to move, so as to drive the spray head 100 to extend or retract relative to the mounting portion 200.

Referring to fig. 2, the nozzle 100 includes a base 11, a first inlet chamber 16, a first outlet chamber 17, a first water passage 20, and a second water passage 21. The first water channel 20 and the second water channel 21 are simultaneously communicated with the first water inlet cavity 16 and the first emergent cavity 17. A first water inlet 14 is arranged on the base body 11, and a first water inlet cavity 16 is arranged in the base body 11 and communicated with the first water inlet 14. A first exit opening 12 is also provided in the base body 11, the first exit opening 12 communicating with a first exit chamber 17. After entering from the first water inlet 14, the water flows through the first water inlet chamber 16, enters the first exit chamber 17 through the first water channel 20 and the second water channel 21, and finally exits from the first exit hole 12, so that the user can clean the water by using the spray.

The base 11 may include a base plate 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 which are opposite to each other. The bottom cover 90 is fixedly connected to the base plate 70. as an embodiment, the bottom cover 90 may be adhered and attached to the first surface 71 by a waterproof glue, and the top cover 80 may be attached to the second surface 72 in the same manner. In some other embodiments, the base plate 70 may be provided with a threaded hole 73, and the threaded hole 73 is respectively disposed on the first surface 71 and the second surface 72 and penetrates through the first surface 71 and the second surface 72. The bottom cover 90 and the top cover 80 may be provided with mounting holes facing the screw holes 73, and the top cover 80 and the bottom cover 90 may be fixedly mounted on the substrate 70 by inserting bolts 74 into the mounting holes and fixedly connecting the bolts to the screw holes 73. In some embodiments, a sealing adhesive strip 75 may be disposed on the first surface 71 and the second surface 72, and the adhesive strip may enable the top cover 80, the bottom cover 90 and the substrate 70 to be sealed in a fitting manner. The base plate 70, the bottom cover 90 and the top cover 80 together constitute a substantially cylindrical base body 11.

Referring to fig. 3 and 4 again, the nozzle 100 further includes a turbulence block 60 disposed in the first water inlet chamber 16, wherein the turbulence block 60 is used for disturbing the water flow, so that the disturbed water flow forms a turbulent flow and flows into the first water channel 20 and the second water channel 21. As an example, the spoiler 60 may be a protrusion formed on an inner wall of the first inlet chamber 16. in other embodiments, the spoiler 60 may be a separate component that fits within the first inlet chamber 16, but is not limited thereto. The flow disturbing block 60 is positioned in the first water inlet cavity 16, and plays a certain role in blocking the flow of water flow and changing the flow direction of the water flow in the blocking process. Since the water flow continues to flow under the action of the water pressure, the water flow changes into a turbulent state with irregular motion after passing through the turbulent block 60, and continues to flow into the first water channel 20 and the second water channel 21.

The sides of the substrate 70 may be generally arcuate. In some embodiments, the outer cover 600 may abut the curved surfaces of both sides of the substrate 70 when the outer cover 600 is sleeved on the base 11. The first and

second water inlets

14 and 15 may be disposed on an end surface of one end of the base plate 70, and configured as a pagoda-shaped interface 23 to facilitate insertion with the water pipe 400. The first inlet chamber 16 may be disposed on the first surface 71 and formed through the first surface 71. The first water inlet 14 communicates with a first water inlet chamber 16. In some embodiments, the second inlet chamber 19 is also disposed on the first surface 71 and is formed through the first surface 71. The second water inlet 15 may be disposed at the same end surface as the first water inlet 14, and an axis of the second water inlet 15 may be disposed substantially parallel to an axis of the first water inlet 14, thus facilitating the connection of the water pipe 400. The second water inlet 15 penetrates the substrate 70 from the end surface of the substrate 70, and then communicates with the second water inlet chamber 19. The first exit cavity 17 may be disposed on the second surface 72 and penetrate the second surface 72. The first waterway 20 is substantially identical to the second waterway 21 and is formed on the substrate 70, the first waterway 20 communicates the first inlet chamber 16 with the first exit chamber 17, and the second waterway 21 also communicates the first inlet chamber 16 with the first exit chamber 17. As an embodiment, referring again to fig. 4, the first water inlet chamber 16 may include a flow stabilizing chamber 161 and a flow dividing chamber 162, the first water inlet 14 is communicated with the flow stabilizing chamber 161, and the flow disturbing block 60 is disposed in the flow stabilizing chamber 161. The water flows into the diversion chamber 162 through the surge chamber 161, and the diversion chamber 162 communicates with the first water passage 20 and the second water passage 21. The cross-section of the distribution chamber 162 may be larger relative to the cross-section of the flow stabilizing chamber 161 so that the flow velocity is relatively reduced when entering the distribution chamber 162 after being disturbed and turbulent by the spoiler 60 in the flow stabilizing chamber 161. Since the flow velocity of the water flow is slow and the state of the water flow is turbulent, the pressure of the water flow acting on the inner wall of the diversion cavity 162 is less influenced by the inertia of the fluid when the fluid flows in each direction, so that the pressure of the fluid relative to the inner wall of the diversion cavity 162 is approximately equal in each direction.

Referring to fig. 5, in some embodiments, the first inlet chamber 16 may also have a 90-degree bend angle, so that when water flows through the first inlet chamber 16, the direction of the water flow changes at the bend of the first inlet chamber 16, and a turbulent flow may be formed into the flow dividing chamber 162. In the present embodiment, the distances between the first waterway 20 and the second waterway 21 may be substantially the same with respect to the first water inlet chamber 16, so that the water flowing through the first water inlet chamber 16 can uniformly enter the first waterway 20 and the second waterway 21 even when entering the splitting chamber 162.

Referring to fig. 6, the first water passage 20 has a first outlet 201 communicated with the first exit chamber 17, and the second water passage 21 has a second outlet 211 communicated with the first exit chamber 17. In one embodiment, the first outlet 201 and the second outlet 211 may be disposed opposite to each other, so that the water sprayed from the first outlet 201 collides with the water sprayed from the second outlet 211 and is sprayed from the first outlet hole 12 after the collision. The first outlet 201 and the second outlet 211 are located at two sides of the first outlet hole 12, so that the first outlet hole 12 is located at the collision point of the water flow sprayed from the first outlet 201 and the water flow from the second outlet 211. The water after collision is sprayed out through the first outlet hole 12, and granular spray can be generated. The granular splash has less irritation to the user and higher comfort level in the process of cleaning the user.

As an embodiment, the diameter a1 of the first flume 20 may be substantially the same as the diameter a2 of the second flume 21. Since the diversion cavity 162 is in communication with the first channel 20 and the second channel 21, the water flows into the first channel 20 and the second channel 21 under the action of pressure. Since the first channel 20 and the second channel 21 have the same diameter, the flow rate of water flowing into the first channel 20 and the second channel 21 is the same. According to the fluid flow equation (Q), which is the average flow velocity (V) × the pipe cross-sectional area (a), the flow rates of the water flowing into the first channel 20 and the second channel 21 are equal to each other because the flow rates of the water flowing into the first channel 20 and the second channel 21 are equal to each other at the flow velocities V1 and V2.

In some embodiments, the first and

second channels

20, 21 further include first and second water-slowing cavities 202, 212. The first water slowing cavity 202 and the second water slowing cavity 212 are arranged on the substrate 70, the first water channel 20 is communicated with the first emergent cavity 17 through the first water slowing cavity 202, and the second water channel 21 is communicated with the first emergent cavity 17 through the second water slowing cavity 212. The first outlet 201 may communicate the first buffer water chamber 202 with the first exit chamber 17, and the second outlet 211 may communicate the second buffer water chamber 212 with the first exit chamber 17. The cross-sectional diameters of the first and second chambers 202 and 212 may be larger than the diameters of the first and

second channels

20 and 21, so that the flow rate of the water flowing through the first and

second channels

20 and 21 may be relatively reduced when the water flows through the first and second chambers 202 and 212. Therefore, when the water flows through the first outlet 201 and the second outlet 211 and flows into the first exit cavity 17, the water can be impacted more uniformly, and the water flow emitted from the first exit hole 12 can be prevented from being inclined.

Referring to fig. 7, the first exit cavity 17 has an exit surface 171 opposite to the first exit hole 12. As one embodiment, exit surface 171 may be substantially arcuate. After the water flow collides with the first exit chamber 17, since the exit surface 171 faces the first exit hole 12, when the water flow in the first exit chamber 17 collides with the exit surface 171, the exit surface 171 can emit the water flow colliding with the exit surface 171 at an angle substantially diverging from the axial direction of the first exit hole 12. Therefore, when the water flow is emitted from the first emitting hole 12, the water flow can be diffused relative to the axial direction of the first emitting hole 12, so that the water flow emitted from the first emitting hole 12 can be emitted approximately along a fan shape, and the cleaning area is increased.

Referring again to fig. 3 and 4, the bottom cover 90 is used to close the first inlet chamber 16. The bottom cover 90 may have a first flat surface 91, and the first inlet chamber 16 may be closed when the first flat surface 91 is engaged with the first surface 71. In some embodiments, the bottom cap 90 also closes the second inlet chamber 19. The first engaging surface 91 may also abut against the sealing rubber strip 75 on the first surface 71, so that the bottom cover 90 may be more tightly closed to the first inlet chamber 16 and the second inlet chamber 19. In some embodiments, a mounting portion 91 may be disposed on the bottom cover 90 away from the first surface 71, and the mounting portion may be used to connect with the driving portion 300, so that the driving portion 300 can drive the nozzle 100 to move by driving the bottom cover 90. In other embodiments, the assembly portion of the bottom cover 90 may abut against the inner side of the outer sleeve 600, and the driving portion 300 may be connected to the outer sleeve 600, so that the driving portion 300 drives the base 11 through the outer sleeve 600, and further, the function of driving the spray head 100 to move is also achieved.

The top cover 80 may have a second flat surface 81, and the second flat surface 81 is attached to the second surface 72 such that the top cover 80 encloses the first exit cavity 17 on the substrate 70. The first exit hole 12 is provided on a side of the top cover 80 away from the second attaching plane 81. In one embodiment, the first exit hole 12 may be circular, with a diameter of about 1.5mm to about 2.5mm and a depth of about 0.50 mm to about 1.20 mm. Thus, when the water flow flowing into the first exit cavity 17 from the first outlet 201 and the second outlet 211 collides with each other and the water flow sprayed from the first exit hole 12 meets the user, the force is comfortable, and the water flow also has a corresponding cleaning effect. The axis of the first exit hole 12 may form an angle C with the second surface 72, and in this embodiment, the angle C formed by the axis and the second surface 72 is an acute angle. When the water flow is sprayed out from the first spraying hole 12, the direction of the water flow is at a certain included angle with the direction of the spray gun 1000, which is convenient for a user to clean when using. By adjusting the angle between the exit port and the second surface 72, the angle of the water stream as it is ejected can be adjusted. The angle can be adjusted according to the needs of the user, and then the best cleaning angle is selected. In other embodiments, the first exit hole 12 may also have a mesh structure capable of dispersing water flow, and since the water flow has a certain water pressure, the water flow can be ejected from the first exit hole 12 through the mesh structure under the action of pressure, which can also achieve the function of dispersing the water flow and increasing the cleaning area.

The use principle of the closestool provided by the embodiment is as follows:

when the user desires to use, the driving part 300 responds to the control means and drives the spray head 100 to be extended along the chute by operating the control means. When the spray head 100 is extended to a designated position, the corresponding valve 50 responds to the control means and causes the water pipe 400 to start supplying water. The water flow enters the flow stabilizing cavity 161 from the first water inlet 14, and the flow state of the water flow is disturbed and forms turbulent flow when the water flow passes through the flow disturbing block 60 in the flow stabilizing cavity 161. The water flows through the steady flow chamber 161, enters the diversion chamber 162, and uniformly enters the first water channel 20 and the second water channel 21 in the diversion chamber 162. The water in the first water channel 20 flows into the first exit chamber 17 through the first outlet 201, and the water in the second water channel 21 flows into the second exit chamber 18 through the second outlet 211. Since the first outlet 201 is opposite to the second outlet 211, the two water flows collide in the first exit chamber 17. During collision, since the first exit hole 12 is disposed between the first outlet 201 and the second outlet 211, the first exit cavity 17 is provided with the exit surface 171 having a semicircular cross section with respect to the first exit hole 12. The water flow is reflected by the semicircular exit surface 171, spreads outward in a fan shape toward the first exit hole 12, and exits in a granular form, thereby achieving a function of cleaning the private parts of the user. Granular water flow has the characteristic of small irritation and has high comfort level, and meanwhile, because the water flow spreads along the fan shape, the area of the water flow which can be cleaned is large, so that the female private parts can be cleaned effectively.

The above embodiments are only for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
