[0046] See also Figure 1 , 2 3. The present invention provides a urinal, comprising a urinal shell 1 and a back plate shell 2, wherein the back of the urinal shell 1 is provided with an opening 11 adapted to the back plate shell 2;

[0047] Among them, a sewage pipe part 12 for discharging sewage is provided at the bag 13 of the toilet shell 1, a boss surface 21 corresponding to the sewage pipe part 12 is provided on one side of the back plate shell 2, the bag 13 is supported on the boss surface 21 through the sewage pipe part 12, and a support part 22 for preventing the boss surface 21 from collapsing is provided on the other side of the back plate shell 2; the back plate shell 2 is provided with a sewage port 23 connected to the sewage pipe part 12, and the sewage pipe part 12 is provided with a boss 121 adapted to the sewage port 23, so that when the toilet shell 1 and the back plate shell 2 are bonded, the connection position relationship can be determined between the sewage port 23 and the boss 121. Preferably, the support portion 22 is in the shape of an arc-shaped rib and is located near the drain port 23 so as to be as close to the drain port 23 as possible to reduce the deformation of the drain port 23 during the grouting molding process, to improve the roundness of the drain port 23, and to ensure the sealing of the subsequent mating access boss 121.

[0048] Specifically, see Figure 4 The backplane shell 2 includes a plate frame body 2a and a concave shell 2b arranged on the plate frame body 2a, and the concave shell 2b corresponds to the shape of the gallbladder bag 13, so that one side of the concave shell 2b forms a backplane space 2c for installing and placing external devices, so that after the plate frame body 2a is installed against the wall, the backplane space 2c can also accommodate pipelines, electrical circuits, etc.

[0049] Furthermore, in order to stabilize the connection relationship between the back plate shell 2 and the toilet shell 1 and the accuracy of their bonding position, the plate frame body 2a is provided with a raised base surface 24 adapted to the opening 11, so that the edge of the plate frame body 2a forms a bonding step surface 25 for bonding with the toilet shell 1, thereby limiting the movement of the toilet shell 1 on the raised base surface 24. At the same time, after the urinal is installed upright, the raised base surface 24 can also play a certain supporting role on the toilet shell 1.

[0050] In order to facilitate the installation of the urinal, a hanging hole 26 for hanging is provided on the top of the plate frame body 2a, so that the urinal can be fixed to the hook of the wall through the hanging hole 26.

[0051] Moreover, the two side walls of the inner concave shell 2b are provided with positioning and fixing grooves 27, and the positioning and fixing grooves 27 are provided with connecting pieces for connecting to the wall. The connecting pieces include a first connecting piece 31 adapted to the positioning and fixing grooves 27 and a second connecting piece 32 for connecting to the wall, so as to support the urinal through the positioning and fixing grooves 27.

[0052] On the other hand, in order to strengthen the connection between the toilet shell 1 and the back plate shell 2, the positioning and fixing groove 27 and the toilet shell 1 are provided with corresponding connecting through holes 4, that is, threaded connectors such as bolts and screws can be provided to pass through the toilet shell 1 and the back plate shell 2 in turn to connect with the first connecting piece 31.

[0053] Correspondingly, the first connecting piece 31 is provided with a screw hole for threaded connection, and the second connecting piece 32 is also correspondingly provided with a strip hole for connecting to the wall, so as to facilitate adjustment of the installation position of the urinal.

[0054] Preferably, the positioning and fixing groove 27 is a trapezoidal groove, and the first connecting piece 31 is correspondingly trapezoidal, so that after the urinal is installed on the wall, the first connecting piece 31 can be restricted from being separated from the positioning and fixing groove 27 in a direction perpendicular to the wall.

[0055] The present invention also provides a method for producing the above urinal, comprising the following steps:

[0056] S01, providing a main body blank mold for producing the toilet shell 1, the main body blank mold includes an upper mold 5a, a lower mold 5b, a left mold 5c and a right mold 5d, so as to facilitate the mold opening, such as Figure 6 The upper mold 5a, the lower mold 5b, the left mold 5c and the right mold 5d are closed to form an internal cavity adapted to the toilet shell 1;

[0057] S02, providing a bottom plate blank mold for producing the back plate shell 2; the bottom plate blank mold includes a top mold 6a and a bottom mold 6b, such as Figure 7 The top mold 6a and the bottom mold 6b are closed to form an internal cavity adapted to the back plate shell 2; since the back plate shell 2 does not have the structure of the chamber bag 13 and the sewage pipe part 12 in the toilet shell 1 that affect the mold opening, only two molds are needed to realize the opening and closing of the back plate shell 2.

[0058] S03, injecting the slurry into the inner cavity of the bottom plate blank mold to obtain the blank of the back plate shell 2,

[0059] For the convenience of description, the blank of the backplane shell 2 is a backplane blank A;

[0060] Injecting the slurry into the inner cavity of the main body blank mold to obtain the blank of the toilet shell. For the convenience of description, the blank of the toilet shell is the main body blank B;

[0061] S04, see Figure 8 and 9, the bottom plate blank mold can be raised by a mechanical arm, and then the bottom mold 6b is opened, leaving the back plate blank at the top mold 6a, and the pallet 7 is sent to the bottom of the top mold 6a by a transportation device, and then the top mold 6a is lowered to make the top mold 6a and the pallet 7 engage, so that the pallet 7 can accurately receive the back plate blank A, and then the top mold 6a is opened to expose the bonding surface of the back plate blank A upward, as shown in FIG. Fig.10 ;

[0062] S05, applying bonding slurry on the bonding surface of the back plate blank A;

[0063] S06, opening the lower mold 5b to expose the bonding surface of the main body blank B downward, such as Fig.11 ;

[0064] S07, the bottom plate blank in the pallet 7 is sent to the bottom of the main body blank B mold by the transport device, and the pallet 7 replaces the lower mold 5b and closes with the upper mold 5a, the left mold 5c and the right mold 5d. Fig.12 The bonding surface of the back plate blank A is bonded to the bonding surface of the main body blank B to obtain a urinal blank. Preferably, the transport device may be a robotic arm or a transport belt.

[0065] S08, open the upper mold 5a, the left mold 5c and the right mold 5d, the urinal blank remains on the support plate 7, and then is moved to the sintering equipment through the transport device for sintering to obtain the urinal, see Fig.13 .

[0066] In order to strengthen the bonding strength between the toilet shell 1 and the back plate shell 2, a first bonding surface A1 is provided around the edge of the back plate blank A; and a second bonding surface A2 is provided on the inner wall of the sewage discharge port 23 of the back plate blank A;

[0067] The back edge of the main body blank B is provided with a third bonding surface B1 for bonding with the first bonding surface A1. The main body blank B is provided with a sewage pipe portion 12. The sewage pipe portion 12 is provided with a boss 121 adapted to the sewage port 23. The sewage pipe portion 12 is bonded to the second bonding surface A2 through the side wall B2 of the boss 121.

[0068] Moreover, since the water content of the back panel blank A and the main body blank B is relatively large, in order to improve the bonding strength between the bonding surfaces, the mud used to make the back panel blank A and the main body blank B is high-pressure mud, and the viscosity of the bonding mud is greater than the viscosity of the high-pressure mud, and the density of the bonding mud is greater than the density of the high-pressure mud.

[0069] Furthermore, since a large amount of water bubbles will flow out when the mold is opened and drip onto the main body blank B bladder bag 13, they can flow away, so that the blank will not be softened by water bubbles.

[0070] In step S04 , the main body B is provided with a water outlet 28 for installing a water spray device. The main body B is tilted on the mold so that when the mold of the main body B is opened, water bubbles inside it flow out from the water outlet 28 .

[0071] Preferably, semicircular notch holes 8 for mold opening and closing positioning are provided on both sides of the support plate 7, and the left mold 5c, the right mold 5d and the top mold 6a are all provided with positioning columns 9 corresponding to the semicircular notch holes. The setting of the semicircular notch holes 8 can facilitate the opening of the left mold 5c and the right mold 5d without lifting them and then moving them left and right.

[0072] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
