[0056] Please see Figures 1-15 As shown, this utility model discloses a urinal, including a urinal body 5, a urinal bowl 52, a drain outlet 51 at the bottom of the urinal bowl 52, and the aforementioned drain structure. The inlet end of the drain pipe 1 is connected to the drain outlet 51 via a connecting sleeve 2. Specifically, the back of the urinal body 5 has a mounting groove 55, and a portion of the drain structure (the part from the inlet end of the drain pipe 1 to the flange 13) is located in the mounting groove 55.

[0057] This utility model also includes a filter cover 6, which is detachably installed at the drain outlet 51. Specifically, the bottom of the toilet bowl 52 is provided with a drain trough 53, and the bottom of the drain trough 53 is provided with the aforementioned drain outlet 51. The filter cover 6 is installed in the drain trough 53. The filter cover 6 has a hollow structure with an open bottom, and the outer peripheral surface of the filter cover 6 is provided with a water inlet 61 that communicates with its inner cavity. The inner wall surface of the filter cover 6 is provided with a limiting groove 62 that fits into the operating handle 22 to limit the position of the filter cover 6.

[0058] This utility model also includes a mounting hook 7, which is fixed to the wall 8, and the top of the urinal body 5 is provided with a hanging groove 54 that cooperates with the mounting hook 7.

[0059] The installation method of this utility model for a urinal is as follows: First, the flange 13 of the drain pipe 1 is fixed to the wall 8 with bolts; then, the mounting hook 7 is installed on the wall 8, and the urinal body 5 is directly hung on the mounting hook 7, while aligning the inlet end of the drain pipe 1 with the drain outlet 51 of the urinal body 5; then, the connecting sleeve 2 is passed through the drain outlet 51 from the bowl 52 of the urinal body 5, clockwise (i.e., ... Figure 7 Rotate the operating handle 22 (in the direction of the arrow) to connect the connecting sleeve 2 to the inlet end of the drain pipe 1; finally, install the filter cover 6 in the drain trough 53 of the urinal body 5. The installation is convenient and the finished product is aesthetically pleasing and simple.

[0060] This utility model relates to a urinal. For details regarding the structure and working principle of the urinal's drainage system, please refer to the preceding description; further details will not be repeated here.

[0061] Example 2

[0062] Please see Figures 16-20 As shown, the urinal's sewage discharge structure and urinal of this utility model differ from Embodiment 1 in that the operating handle 22 is connected to the connecting sleeve 2 through the breakable connection structure 23. The breakable connection structure 23 is configured such that after the connecting sleeve 2 and the sewage pipe 1 are threadedly connected, the operating handle 22 can be separated from the sleeve body 21 by applying an external force in a predetermined direction.

[0063] The easily broken connection structure 23 includes at least one of the following: a weak groove, a thickness reduction region, a stress concentration notch, a perforated connection band, and a brittle material connection part, but is not limited thereto.

[0064] In this embodiment, the operating handle 22 is plate-shaped, but not limited to this. It extends along the axial direction of the sleeve body 21, and the two ends of the bottom of the operating handle 22 form two connecting parts 221, which are connected to the top surface of the sleeve body 21. Specifically, the easily breakable connection structure 23 is a stress concentration notch, and stress concentration notches are respectively provided on the outer side of the two connecting parts 221 (i.e., the side of the connecting part 221 away from the axis of the sleeve body 21). After the sewage pipe 1 is connected to the urinal body 5, the operating handle 22 can be broken off directly, such as... Figure 21 As shown, the flushing effect is better in this state. In other embodiments, the operating handle may be inverted U-shaped.

[0065] The top surface of the sleeve body 21 is provided with a stop structure. After the operating handle 22 is detached from the sleeve body 21, it abuts against the stop structure to drive the rotation of the sleeve body 21. Furthermore, when the drain pipe 1 is connected to the urinal body 5, and the operating handle 22 is separated from the sleeve body 21, even if the operating handle 22 cannot be found, when it is necessary to disassemble the drain pipe 1 and the urinal body 5, another plate-like object can be used to replace the operating handle 22, abutting against the stop structure to still allow the sleeve body 21 to rotate. When the connecting sleeve 2 is not in use, the stop structure also prevents the operating handle 22 from being bent by external force and prematurely separating from the sleeve body 21.

[0066] The stop structure includes a stop boss 24 provided on the top surface of the sleeve body 21 on one side of each connecting part 221 along the circumference of the sleeve body 21. The two connecting parts 221 are respectively arranged adjacent to the stop boss 24 on one side, and the stop boss 24 corresponding to the two connecting parts 221 are located on different sides. The stop boss 24 is an arc shape extending along the circumference of the sleeve body 21.

[0067] The installation method of this utility model urinal is roughly the same as that of Embodiment 1. The difference is that after the connecting sleeve 2 is threadedly connected to the inlet end of the drain pipe 1, the operating handle 22 needs to be broken off before the filter cover 6 is installed in the drain trough 53 of the urinal body 5.

[0068] Example 3

[0069] Please see Figures 22-23 As shown, the urinal drainage structure and urinal of this utility model differ from Embodiment 2 in that the stop structure includes stop bosses 24 respectively provided on both sides of each connecting part 221 along the circumference of the sleeve body 21 on the top surface of the sleeve body 21, and each connecting part 221 is arranged adjacent to the stop bosses 24 on both sides.

[0070] The present invention relates to a urinal drainage structure and a urinal, the parts not described herein are the same as or can be implemented using existing technology.

[0071] The above embodiments are only used to further illustrate the sewage discharge structure and urinal of this utility model. However, this utility model is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
