[0035] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a cleaning mechanism, which includes a driving motor (not shown), a gear assembly 100, a transmission belt 200 and a spray bar 300. Among them, the gear assembly 100 includes a driving wheel 110 and an output wheel 120, the driving motor is coaxially connected to the driving wheel 110, and the diameter of the driving wheel 110 is larger than the diameter of the output shaft of the driving motor. In this embodiment, the output wheel 120 is provided with a first gear ring 121 and a second gear ring 122 arranged coaxially, and the diameter of the second gear ring 122 is larger than the diameter of the first gear ring 121, the driving wheel 110 is transmission-connected to the first gear ring 121, the second gear ring 122 is transmission-connected to the transmission belt 200, and the spray bar 300 is connected to the transmission belt 200. During movement, the driving motor drives the driving wheel 110 to rotate forward and reverse, and then drives the output wheel 120 to rotate forward and reverse, and then drives the transmission belt 200 and the spray bar 300 to move forward and backward together.

[0036] In other embodiments, the output wheel 120 may be provided with more than two coaxially arranged gear rings, which may be arranged according to actual product requirements.

[0037] The cleaning mechanism of this embodiment can achieve double speed increase because the diameter of the driving wheel 110 is larger than the diameter of the output shaft of the drive motor, and the diameter of the second gear ring 122 is larger than the diameter of the first gear ring 121, so that it can ensure that even if the diameter of the driving wheel 110 is not increased, the speed of the transmission belt 200 can be greatly increased. The cleaning mechanism of this structure avoids the situation where the diameter of the driving wheel 110 is increased in order to increase the speed of the transmission belt 200, resulting in the cleaning mechanism occupying too much volume. In addition, due to this cleaning mechanism, when increasing the speed of the transmission belt 200, there is no need to increase the output speed of the drive motor, so the output torque of the drive motor will not be reduced, and the smooth movement of the spray rod 300 can be well guaranteed.

[0038] like Figure 1 and Figure 3 As shown, in this embodiment, the driving wheel 110 is meshed with the first gear ring 121, and the second gear ring 122 is meshed with the transmission belt 200. Of course, in other embodiments, the gear assembly 100 may also include one or more driven wheels, the driven wheel having two gear rings of different diameters arranged coaxially, these driven wheels are arranged between the driving wheel 110 and the output wheel 120 in meshing transmission, and these driven wheels are also arranged in a speed-increasing manner. These driven wheels not only play the role of transmission connection between the driving wheel 110 and the output wheel 120, but also can further enhance the speed-increasing effect.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the cleaning mechanism further includes a connecting member 400, one end of which is provided with a connecting portion connected to the spray rod 300, and the other end of which is provided with a clamping buckle that is tightly matched with the transmission belt 200. Through the connecting portion and the clamping buckle, the connecting member 400 can well connect the spray rod 300 and the transmission belt 200. Specifically, the clamping buckle can be clamped to the transmission belt 200 by snapping, and the connecting portion can be connected to the spray rod 300 by existing methods such as shaft groove matching.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the cleaning mechanism further includes a first guide wheel 500 and a second guide wheel 600. The transmission belt 200 is respectively wrapped around the first guide wheel 500, the second guide wheel 600 and the output wheel 120, so that the transmission belt 200 can be transmitted in the shape surrounded by the first guide wheel 500, the second guide wheel 600 and the output wheel 120. It should be noted that the connecting member 400 is connected to the transmission belt 200 located between the first guide wheel 500 and the second guide wheel 600. Driven by the transmission belt 200, the connecting member 400 can move forward and backward between the first guide wheel 500 and the second guide wheel 600, thereby realizing the forward and backward movement of the spray rod 300.

[0041] In addition, in this embodiment, the cleaning mechanism further includes a bracket, and a guide rail is provided at the upper end of the bracket, the spray rod 300 is telescopically and movably arranged on the guide rail, and the gear assembly 100 and the transmission belt 200 are located on one side of the bracket. This structure is not only conducive to the smooth movement of the spray rod 300, but also because the gear assembly 100 and the transmission belt 200 are located on one side of the bracket, it is conducive to saving space in the vertical direction of the cleaning mechanism.

[0042] In addition, if Figure 1 and Figure 2 As shown, in this embodiment, the cleaning mechanism further includes a tensioning part, which is used to tension the transmission belt 200, so that the transmission belt 200 is in a taut state to avoid the transmission belt 200 from slipping and transmission failure, and to ensure the transmission stability of the transmission belt 200. In this embodiment, the tensioning part is a tensioning spring 700. Of course, in other embodiments, the tensioning part can be a tensioning spring 700 or a tensioning wheel. The tensioning spring 700 and the tensioning wheel belong to the prior art in the field and will not be described in detail here.

[0043] In addition, the present embodiment further provides a toilet, which includes a toilet seat, a cover mechanism, a water tank mechanism and a cleaning mechanism. Among them, the cleaning mechanism is the cleaning mechanism provided by the present embodiment above, and the spray rod 300 of the cleaning mechanism is provided with a cleaning water path for cleaning the human body part, and the water supply of the cleaning mechanism comes from the water tank mechanism or external municipal water. The cleaning water path of the spray rod 300 and its working principle belong to the prior art in the field and will not be described here. Since the cleaning mechanism of this toilet is the cleaning mechanism provided by the present embodiment above, its spray rod 300 has a faster moving speed, which can not only move faster to the desired position for cleaning, but also has a stronger cleaning effect in the moving cleaning state due to its faster reciprocating motion.

[0044] The cleaning mechanism and the toilet provided in the above embodiment can greatly increase the speed of the transmission belt 200 without increasing the diameter of the driving wheel 110 through the double speed increase of the driving wheel 110 and the output wheel 120. This cleaning mechanism avoids the situation where the diameter of the driving wheel 110 is increased in order to increase the speed of the transmission belt 200, resulting in the cleaning mechanism occupying too much volume. In addition, due to this cleaning mechanism, when increasing the speed of the transmission belt 200, there is no need to increase the output speed of the drive motor, so the output torque of the drive motor will not be reduced, and the smooth movement of the spray rod 300 can be well guaranteed.
