[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0039] The described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solution of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be used. In other cases, known structures, materials or operations are not shown or described in detail to avoid blurring the various aspects of the present invention.

[0040] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0041] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a spray rod mechanism, which includes a drive assembly, a transmission belt 200, a spray rod 300 and a seat body 800. The seat body 800 is provided with an arc guide portion 810, the spray rod 300 is movably arranged on the arc guide portion 810, and the transmission belt 200 is located on the side of the seat body 800. During specific movement, the drive assembly drives the transmission belt 200 to transmit forward and backward, and the transmission belt 200 that transmits forward and backward drives the spray rod 300 to move forward and backward along the arc guide portion 810. Figure 1 , Figure 2 and Figure 3 The spray bar mechanism shown in the figure shows that the spray bar 300 is in the state of not extending, partially extending and fully extending. It should be noted that the arc guide portion 810 can be an arc guide rail arranged on the seat body 800, and the spray bar 300 can be movably arranged on the arc guide rail. Of course, in other embodiments, the seat body 800 is provided with a mounting cavity, and the transmission belt 200 can also be arranged inside the seat body 800, which will not be repeated here. This spray bar mechanism allows the spray bar 300 to move forward and backward along the arc guide portion 810. This movement mode allows the water sprayed by the spray bar 300 to have a larger change angle. Compared with the spray bar 300 moving along a straight line, this mode allows the spray bar 300 to achieve the original flushing range within a smaller moving range, which can greatly facilitate the spatial arrangement of the toilet and the miniaturization of the toilet, and has good practicality. In addition, since the transmission belt 200 is located on the side of the spray bar 300, the size of the spray bar mechanism in the up and down direction can be reduced, which can free up more favorable space for the toilet and further facilitate the spatial arrangement of the toilet.

[0042] like Figure 2 and Figure 3As shown, in this embodiment, the spray bar mechanism further includes a connecting member 400, which is connected to the transmission belt 200 and is located on the side of the spray bar 300. The connecting member 400 includes a movable portion 410 and a clamping portion 420, the clamping portion 420 is clamped on the transmission belt 200, and the movable portion 410 is used to connect with the spray bar 300. Specifically, the clamping portion 420 is a clamping buckle, which can be firmly clamped on the transmission belt 200. The movable portion 410 is provided with a strip-shaped movable groove 411, and the spray bar 300 is provided with a convex rod 310, which is inserted into the movable groove 411. During specific activities, the transmission belt 200 can drive the movable portion 410 and the clamping portion 420 to move forward and backward together. Since the convex rod 310 is limited by the movable groove 411 in the direction of forward and backward movement, the connecting member 400 can drive the spray bar 300 to move forward and backward together. In addition, when the connecting member 400 drives the spray rod 300 to move forward and backward along the arc guide portion 810, the convex rod 310 can move along the movable groove 411 to adapt to the distance change between the arc guide portion 810 and the transmission belt 200, so that the connecting member 400 can smoothly drive the spray rod 300 to move forward and backward along the arc guide portion 810. It should be noted that in this embodiment, the movable groove 411 is not parallel to the movement direction of the connecting member 400, so that when the connecting member 400 drives the spray rod 300 to move forward and backward along the arc guide portion 810, the convex rod 310 can adapt to the distance change between the arc guide portion 810 and the transmission belt 200.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the movable portion 410 and the clamping portion 420 are an integrated structure, which can ensure the stability of the connection between the movable portion 410 and the clamping portion 420. Of course, in other embodiments, the movable portion 410 and the clamping portion 420 can be independent parts, which are detachably connected together by screws, buckles, etc.

[0044] like Figure 2 and Figure 3As shown, in this embodiment, the driving assembly includes a driving motor, a driving wheel 100a and an output wheel 100b, wherein the driving motor is coaxially connected to the driving wheel 100a, and the output wheel 100b 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, and the driving wheel 100a is transmission-connected to the first gear ring 121, and the second gear ring 122 is transmission-connected to the transmission belt 200. During specific movement, the driving motor drives the driving wheel 100a to rotate forward and reverse, and then drives the output wheel 100b to rotate forward and reverse, thereby driving the transmission belt 200 and the spray bar 300 to move forward and backward together. It should be noted that most of the time, since the diameter of the driving wheel 100a is larger than the diameter of the output shaft of the driving motor, and the diameter of the second gear ring 122 is larger than the diameter of the first gear ring 121, it is possible to achieve two speed increases, which can greatly increase the speed of the spray bar 300 moving forward and backward.

[0045] like Figure 2 and Figure 3 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 100b, and 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 100b. 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, and the transmission belt 200 between the first guide wheel 500 and the second guide wheel 600 is linear. Driven by the transmission belt 200, the connecting member 400 can move linearly back and forth between the first guide wheel 500 and the second guide wheel 600, thereby realizing the forward and backward movement of the spray rod 300.

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the cleaning mechanism further includes a tensioning spring piece 700a, which is used to tension the transmission belt 200 so that the transmission belt 200 can remain in a taut state to avoid slipping and transmission failure of the transmission belt 200, thereby ensuring the transmission stability of the transmission belt 200. It should be noted that the tensioning spring piece 700a belongs to the prior art in this field and will not be described in detail here.

[0047] In addition, if Figure 4 , Figure 5 and Figure 6As shown, this embodiment also provides another embodiment, in which the spray rod mechanism includes a driving assembly, a transmission belt 200, a connecting member 400, a spray rod 300 and a seat 800. The driving assembly includes a driving motor and a driving wheel 100c, the driving motor is coaxially connected to the driving wheel 100c, and the driving wheel 100c is directly connected to the driving belt 200. The connection structure and working principle of the driving belt 200, the connecting member 400, the spray rod 300 and the seat 800 are similar to those of the above embodiment. The seat 800 is also provided with an arc guide portion 810, and the spray rod 300 can also be movably arranged on the arc guide portion 810. The driving belt 200 is also located on the side of the spray rod 300, and the details are not repeated here. During specific operation, the driving motor drives the driving wheel 100c to rotate forward and reverse, thereby driving the driving belt 200 and the spray rod 300 to move forward and backward together.

[0048] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the spray rod mechanism further includes a first guide wheel 500, a second guide wheel 600 and a tension wheel 700b, and the transmission belt 200 is respectively wrapped around the first guide wheel 500, the second guide wheel 600, the tension wheel 700b and the driving wheel 100c. The tension wheel 700b is used to tension the transmission belt 200 so that the transmission belt 200 can be kept in a taut state. It should be noted that the tension wheel 700b also belongs to the prior art in this field and will not be described in detail here.

[0049] In addition, the present embodiment further provides a toilet, which includes a toilet seat, a cover mechanism, a water tank mechanism and a spray rod mechanism. The spray rod mechanism is the cleaning mechanism provided in the present embodiment, and the water supply of the cleaning mechanism comes from the water tank mechanism or external municipal water. Since the spray rod mechanism of the toilet is the spray rod mechanism provided in the present embodiment, the spray rod mechanism can free up more space for the toilet, so that the toilet can be better arranged in space.

[0050] The cleaning mechanism and toilet provided by the above embodiment, the spray rod 300 can move forward and backward along the arc guide portion 810. This movement mode can make the water sprayed by the spray rod 300 have a larger change angle. Compared with the spray rod 300 moving along a straight line, this mode can make the spray rod 300 achieve the original flushing range within a smaller moving range, which can greatly facilitate the spatial arrangement of the toilet and the miniaturization of the toilet, and has good practicality. In addition, since the transmission belt 200 is located on the side of the spray rod 300, the size of the spray rod mechanism in the up and down direction can be reduced, which can free up more favorable space for the toilet and further facilitate the spatial arrangement of the toilet.
