Of course, no transmission shaft may be provided.

[0061] A toilet is provided with a cleaning spray rod 3 as described in any one of the above items.

[0062] The utility model has the following working principle:

[0063] One end of the universal joint transmission member 5 is connected to the switching motor, and the other end is connected to the limit shaft 51 or the rear cover 4112. When the switching motor rotates, the universal joint transmission member 5 can drive the limit shaft 51 or the rear cover 4112 to rotate (so that it can transmit power in the arc-shaped spray rod 3), thereby driving the nozzle core 411 to rotate, and the nozzle core 411 then drives the nozzle assembly 4 to rotate.

[0064] A limiting groove 8 is provided on the nozzle housing 44, and a limiting rib 9 is provided on the spray rod body 33. The width of the limiting groove 8 is greater than the width of the limiting rib 9. The limiting groove 8 cooperates with the limiting rib 9 so that the nozzle assembly 4 can only rotate forward and reverse within a specified angle range. Increasing the width of the limiting groove 8 can increase the angle range of the forward and reverse rotation of the nozzle assembly 4.

[0065] A limiting rib A53 is provided on the limiting shaft 51 or the universal joint transmission member 5, and a limiting rib B54 is provided on the spray rod body 33. When the switching motor drives the limiting shaft 51 to rotate on the spray rod body 33, the cooperation between the limiting rib A53 and the limiting rib B54 allows the switching motor to find the initial position.

[0066] In the initial position state, the center of the first nozzle 4121, the center of the water spray hole 42 and the center of the water hole 31 overlap, and the limiting rib 9 of the spray rod body 33 is located in the middle of the limiting groove 8 of the nozzle housing 44 (see Fig. 9 A).

[0067] When the nozzle 412 is switched, the switching motor drives the nozzle core 411 to rotate. Since the sealing ring of the nozzle core 411 and the nozzle shell 44 are in interference fit, the friction between the sealing ring and the nozzle shell 44 can drive the nozzle shell 44 to rotate together when the nozzle core 411 rotates, until the limiting groove 8 of the nozzle shell 44 is limited by the limiting rib 9 of the spray rod body 33 ( Fig. 9 B).

[0068] After the limiting groove 8 is limited by the limiting rib 9, the nozzle shell 44 can no longer rotate, and the nozzle inner core 411 can continue to rotate under the drive of the switching motor to overcome the friction between the sealing ring and the nozzle shell 44 ( Fig. 9 C).

[0069] The switching motor (stepping motor) stops when it rotates to the set position. At this time, the center of the second nozzle 4122 overlaps with the center of the water spray hole 42 ( Fig. 9 D).

[0070] The switching motor rotates in the reverse direction to drive the nozzle inner core 411 to rotate in the reverse direction, and drives the nozzle outer shell 44 to rotate in the reverse direction together, and stops after rotating to the set position. At this time, the center of the second nozzle 4122, the center of the water spray hole 42 and the center of the water hole 31 overlap, and the switching steps of the nozzle 412 are completed. The switching steps of the remaining nozzles 412 are the same as above ( Fig. 9 F).

[0071] During the process of the nozzle 412 spraying the cleaning water column, the switching motor can perform repeated forward and reverse movements within a certain angle range, driving the nozzle assembly 4 to also perform corresponding repeated forward and reverse rotations around the central axis, thereby forming a lateral swing of the water pattern, which can increase the cleaning area and have a certain massage effect. The forward and reverse angle range of the nozzle assembly 4 shall not exceed the angle range defined by the cooperation of the limiting groove 8 on the nozzle assembly 4 and the limiting rib 9 on the spray rod body 33.

[0072] By controlling the speed of the switching motor's forward and reverse rotation, the speed of the water pattern's lateral swing can be controlled. The switching motor can also be controlled to pause intermittently during the forward and reverse rotation process to obtain different lateral swing effects. In addition, the telescopic motor can be superimposed to drive the cleaning spray bar 3 to move forward and backward, thereby obtaining a multi-dimensional water discharge effect (such as Fig.11 (as shown in A, B, and C).

A spray bar cleaning device, characterized in that: include: A base, provided with an arc-shaped guide rail; The spray rod is arc-shaped and matches the curvature of the arc-shaped guide rail, and is installed on the arc-shaped guide rail; A spray head assembly, wherein the spray head assembly has a water spray hole and is connected to a water source; The driving assembly is provided with a universal joint transmission member and a driving member. The universal joint transmission member is arranged in the spray rod, one end of the universal joint transmission member is connected to the driving member, and the other end of the universal joint transmission member is connected to the spray head assembly for driving the spray head assembly to move.

2. A cleaning spray bar according to claim 1, characterized in that: The universal joint transmission element is a cross universal coupling, a ball-fork type universal coupling or a ball-cage type universal coupling.

3. A cleaning spray bar according to claim 2, characterized in that: The universal joint transmission component is composed of a driving shaft, a driven shaft and a universal joint. The driving shaft is fixedly connected to the driving component. The driving shaft and the driven shaft are connected through a universal joint. The driven shaft is fixedly connected to the nozzle assembly in one piece or in a separate piece.

4. A cleaning spray bar according to claim 3, characterized in that: A plurality of transmission shafts and universal joints are also included between the driving shaft and the driven shaft.

5. A cleaning spray bar according to claim 1, characterized in that: The nozzle assembly includes an adjusting member with multiple water outlets and a nozzle shell, the adjusting member includes a nozzle inner core, the water outlet is arranged on the nozzle inner core, and the water spray hole is arranged on the nozzle shell.

6. A cleaning spray bar according to claim 1, characterized in that: The driving member is driven so that the universal joint transmission member drives the nozzle assembly to swing within a preset angle range.

7. A cleaning spray bar according to claim 1, characterized in that: The nozzle assembly also includes a sealing cover, a water inlet cavity is arranged in the sealing cover, a water inlet joint is arranged on the sealing cover, the water inlet joint is connected to a water pipe, the water pipe is arranged on the spray rod, and the water pipe is connected to a water source.

8. A cleaning spray bar according to claim 5, characterized in that: A limiting assembly is provided between the spray rod and the nozzle housing, for limiting the rotation angle of the nozzle housing relative to the spray rod; the limiting assembly comprises a limiting groove and a limiting rib, the limiting rib is provided on one of the spray rod and the nozzle housing, the limiting groove is opened on the other of the spray rod and the nozzle housing, the limiting rib is sunken in the limiting groove, and the circumferential dimension of the limiting rib is smaller than the circumferential dimension of the limiting groove.

9. A cleaning spray bar according to claim 5, characterized in that: A limiting rib A is arranged on the circumferential surface of one side where the universal joint transmission member is connected to the adjusting member, and a limiting rib B is arranged inside the spray rod at a position opposite to the limiting rib A. The limiting rib A and the limiting rib B cooperate to determine the initial rotation position of the driving member.
