[0038] like Figures 1 to 7 As shown, this is a urinal according to one embodiment of the present invention.

[0039] Please see Figures 1-7 As shown, the urinal of this embodiment includes a urinal body 200, a flushing system 100, and a drain pipe 300. The urinal body 200 is provided with a urine collection tank 203, a rear chamber 204, and a first mounting hole 201. The flushing system 100 includes a foam generator 10, a water outlet assembly 20, a probe assembly 30, a nozzle 40, and a power supply assembly 50. The foam generator 10, the water outlet assembly 20, and the power supply assembly 50 are all disposed within the urinal body 200. The probe assembly 30 is disposed on the urinal body 200 or the nozzle 40. The nozzle 40 is installed in the first mounting hole 201 and is provided with a water outlet 4113 and a foam outlet 4114. The foam outlet 4114 is located outside the water outlet 4113. The foam generator 10... The liquid outlet is connected to the foam outlet 4114, the water outlet component 20 is connected to the water outlet 4113, the probe component 30 is connected to the foam generator 10 and the water outlet component 20 respectively, and the power supply component 50 is connected to the water outlet component 20, the probe component 30 and the foam generator 10 respectively. The power supply component 50 is used to provide power to the electronic components in the flushing system 100. The drain pipe 300 is installed in the urinal body 200 and is connected to the urine collection tank 203. When the probe component 30 senses a signal (human body leaves), it feeds back to the foam generator 10 and the water outlet component 20. The foam generator 10 starts to produce foam and makes thick foam enter and spray out through the foam outlet 4114. The water flows through the water outlet component 20 and sprays out from the water outlet 4113.

[0040] Optionally, the urinal body 200 is provided with a rear chamber 204, and the drain pipe 300, the foam generator 10, the water outlet assembly 20 and the power supply assembly 50 are all located in the rear chamber 204.

[0041] The urinal of this invention has the following advantages:

[0042] First, the urinal of this invention has foaming and cleaning functions. During use, it generates foam to form a foam shield, which effectively prevents sewage and urine from splashing out due to insufficient depth of the urine collection tank 203. When rinsing, the foam liquid can not only keep the inner wall clean, but also wash away odors and prevent bacterial growth.

[0043] Secondly, the flushing system 100 has a high degree of integration by setting the foam outlet 4114 and the water outlet 4113 on the same nozzle 40, which can improve the compactness of the flushing system 100 and reduce the installation process. Furthermore, the foam outlet 4114 is located outside the water outlet 4113, which makes the foam spray angle closer to the urine collection tank 203 of the urinal. The water jet from the water outlet 4113 can contact the inner wall of the small urinal earlier, which can increase the coverage of the foam and improve the flushing effect.

[0044] Please refer to this carefully. Figure 4 and Figure 5 As shown, exemplarily, the nozzle 40 includes a nozzle body 41, a water inlet connector 42, and a foam connector 43. The nozzle body 41 is provided with a water outlet 4113, a foam outlet 4114, a water outlet channel 4111 communicating with the water outlet 4113, and a foam outlet channel 4112 communicating with the foam outlet 4114. The foam outlet channel 4112 is located above the water outlet channel 4111. The nozzle body 41 is installed in the first mounting hole 201. The nozzle body 41 is provided with a water inlet connector 4131 and a foam connector 43. 4132, the water inlet pipe connection hole 4131 is connected to the water outlet channel 4111, the foam pipe connection hole 4132 is connected to the foam outlet channel 4112, the water inlet connection pipe 42 is installed in the water inlet pipe connection hole 4131, the water outlet component 20 is connected to the water inlet connection pipe 42, the foam connection pipe 43 is installed in the foam pipe connection hole 4132, and the foam generator 10 is connected to the foam connection pipe 43. The nozzle 40 has a reasonable structure and adopts a flat stacking method, which not only ensures the effect of water output and foam output, but also takes into account the thickness of the nozzle 40.

[0045] Thick foam enters the foam outlet channel 4112 through the foam connector 43 and is finally sprayed out through the foam outlet 4114. Water flows through the water outlet component 20, through the water inlet connector 42 and the water outlet channel 4111, and is finally sprayed out through the water outlet 4113.

[0046] Furthermore, the nozzle 40 also includes a first connector 44. The nozzle body 41 includes an end head 411, an annular connecting portion 412, and a first mounting portion 413. The water outlet channel 4111 and the foam outlet channel 4112 are disposed on the end head 411. The annular connecting portion 412 is disposed on the end head 411. The first mounting portion 413 is disposed on the end head 411 and located inside the annular connecting portion 412. The first mounting portion 413 is provided with a water inlet pipe connection hole 4131 and a foam pipe connection hole 4132. The annular connecting portion 412 is installed in the first mounting hole 201. The first connector 44 is connected to the annular connecting portion 412 and is used to fix the nozzle body 41 on the urinal body 200. By reasonably setting the structure of the nozzle body 41, the compactness of the nozzle body 41 can be improved, and the installation and removal of the nozzle 40 can be facilitated.

[0047] When installing the nozzle 40, first loosen the first connector 44, with the end head 411 located on the outside of the urinal. Insert the annular connector 412 into the first mounting hole 201, and then tighten the first connector 44 to fix the nozzle 40 to the urinal.

[0048] Optionally, the first connector 44 is threadedly connected to the annular connector 412, which is a simple and reliable connection method that is easy to disassemble and fix.

[0049] Specifically, the first connector 44 is a dodecagonal threaded lock.

[0050] Understandably, the first connector 44 can also adopt other connection structures, such as connecting screws, which can be used to fix the nozzle 40 to the urinal.

[0051] Optionally, the nozzle 40 also includes a first gasket 47 sleeved on the annular connecting part 412. The first gasket 47 is located between the first connector 44 and the end head 411. The number of first gaskets 47 can be set according to actual needs. By setting the first gasket 47, wear between the first connector 44 and the urinal can be avoided.

[0052] Please refer to this carefully. Figure 4 and Figure 5 As shown, exemplarily, the water inlet pipe connection hole 4131 is provided with an internal thread, and the water inlet connection pipe 42 is threadedly connected to the first mounting part 413. The connection method is simple and easy to disassemble and assemble.

[0053] Furthermore, the nozzle 40 also includes a first connecting screw 48, a first mounting part 413 is provided with a first fixing hole 4133 adapted to the first connecting screw 48, a first fixing part 421 is provided on the water inlet connecting pipe 42, and a second fixing hole 422 adapted to the first connecting screw 48 is provided on the first fixing part 421. The first connecting screw 48 passes through the second fixing hole 422 and connects with the first fixing hole 4133. This design can further improve the connection reliability between the water inlet connecting pipe 42 and the first mounting part 413.

[0054] Please refer to this carefully. Figure 4 and Figure 5 As shown, by way of example, the nozzle 40 also includes a connecting ring 49, which is disposed at one end of the water inlet pipe connecting hole 4131 adjacent to the water outlet channel 4111. That is, the water inlet connecting pipe 42 presses the connecting ring 49 into the water inlet pipe connecting hole 4131. By setting the connecting ring 49, the sealing performance between the water inlet connecting pipe 42 and the water inlet pipe connecting hole 4131 can be improved.

[0055] Optionally, the connecting ring 49 is a plastic connecting ring 49.

[0056] Furthermore, the nozzle 40 also includes a first sealing ring 401, which is sleeved on the water inlet connecting pipe 42 and located between the water inlet connecting pipe 42 and the water inlet pipe connecting hole 4131.

A probe mounting hole (not shown) is provided on the end head 411. The probe assembly 30 is mounted in the probe mounting hole. The nozzle outer frame assembly 45 is sleeved on the end head 411. The nozzle outer frame assembly 45 has a notch 4511 adapted to the bubble outlet 4114 and the water outlet 4113. By integrating the probe assembly 30 onto the nozzle 40, the integration of the nozzle 40 can be further improved, and there is no need to install the probe assembly 30 in a separate location on the urinal. Furthermore, the nozzle 40 also includes a nozzle outer frame assembly 45, which serves a waterproof function, preventing external water stains and dust from entering the interior of the nozzle 40 and affecting the service life of the probe assembly 30.

[0058] Optionally, the outer frame assembly includes a nozzle outer frame 451 sleeved on the end head 411 and a sensing window 452 disposed on the end face of the nozzle outer frame 451.

[0059] Specifically, the sensor window 452 is a transparent sensor window 452.

[0060] Optionally, the probe assembly 30 includes a sensing probe 31 and a sensing probe frame 32, wherein the sensing probe 31 is mounted on the sensing probe frame 32 and the sensing probe frame 32 is mounted on the probe mounting hole.

[0061] Furthermore, the rinsing system 100 also includes a signal line assembly 60, with the foam generator 10 and power supply assembly 50 respectively connected to the signal line assembly 60. The nozzle body 41 also includes a second mounting part 414, which is located within the annular connecting part 412 and connected to the first mounting part 413. The second mounting part 414 is provided with a signal line mounting channel 4141, in which the signal line assembly 60 is installed and connected to the sensing probe 31.

The second connecting screw 402 passes through the third fixing hole 4143 and connects with the fourth fixing hole 4134. The connection method between the second mounting part 414 and the first mounting part 413 is simple and reliable.

[0063] Optionally, the signal line assembly 60 includes a sensing signal line 61, a bubble-making signal line 62, and a power line 63. The bubble-making signal line 62 and the power line 63 are respectively connected to the sensing signal line 61, the bubble-making host 10 is connected to the bubble-making signal line 62, and the power supply assembly 50 is connected to the power line 63.

[0064] Furthermore, the nozzle 40 also includes a signal wire fixing piece 46, which is installed at the end of the signal wire mounting channel 4141 away from the probe assembly 30. The signal wire fixing piece 46 is provided with a locking hole 461 that is adapted to the sensing signal wire 61. By fixing the sensing signal wire 61 with the signal wire fixing piece 46, the sensing signal wire 61 can be prevented from getting tangled with other structures.

[0065] Please refer to this carefully. Figures 1-3 As shown, by way of example, the foaming host 10 includes a foaming liquid storage box 11 and a foaming machine 12. The foaming liquid storage box 11 is provided with a liquid chamber 111 and an installation cavity (not shown). The liquid chamber 111 contains foaming agent. The foaming machine 12 is installed in the installation cavity, and the liquid inlet of the foaming machine 12 is connected to the liquid chamber 111. The liquid outlet of the foaming machine 12 is connected to the foaming channel 4112. The foaming host 10 has a simple structure and strong practicality.

[0066] Optionally, the foaming liquid storage box 11 is provided with screw mounting holes (not shown in the figure), and the foaming liquid storage box 11 is fixed to the urinal by screw connection, which is convenient for installation.

[0067] Furthermore, the foam making host 10 also includes a foam outlet pipe 13. One end of the foam outlet pipe 13 is connected to the foaming liquid storage box 11, and the other end is connected to the foam connecting pipe 43. The foam from the foam making machine 12 flows through the foam outlet pipe 13 and the foam connecting pipe 43 and then enters the foam outlet 4114. By setting the foam outlet pipe 13 and the foam connecting pipe 43, the positional restrictions between the foam making machine 12 and the nozzle 40 can be reduced.

[0068] Please see Figure 1 , Figure 6 and Figure 7 As shown, exemplarily, the urinal body 200 is provided with a second mounting hole 202.

The press cover plate 72 is installed on the injection body 71 and is used to seal the injection hole 712. Since the foaming agent is a consumable, it is necessary to replenish the foaming agent in the liquid chamber 111 after a period of use. The injection mechanism 70 can conveniently add foaming agent into the liquid chamber 111. Moreover, the injection mechanism 70 adopts the press-to-open method, which can reduce the pre-reserved buckle required for traditional opening and eliminate the accumulation of dust.

[0069] When foaming agent needs to be injected, the operator presses the pressing cover 72, which pops out the injection hole 712. The operator can then remove the pressing cover 72 and inject the foaming agent into the injection hole 712.

[0070] Specifically, the second mounting hole 202 is located on the top of the urinal body 200.

[0071] Preferably, the injection body 71 is provided with a stepped hole 713, and the pressing cover plate 72 includes an end cap 721, a sealing plunger 722, and a spring 723.

[0077] Specifically, the second connector 73 is a threaded lock.

[0078] When installing the injection mechanism 70, first loosen the second connector 73. The flange 711 of the injection body 71 is located on the outside of the urinal.

[0082] Please refer to this carefully. Figures 1-3 As shown, exemplarily, the water outlet assembly 20 includes a water outlet pipe 21 and an electric angle valve 22. The electric angle valve 22 is electrically connected to the power supply assembly 50. One end of the water outlet pipe 21 is connected to the water inlet connection pipe 42, and the other end is connected to the outlet of the electric angle valve 22. The electric angle valve 22 is used to connect to the water supply device. The water output of the water outlet pipe 21 can be controlled by setting the electric angle valve 22.

[0083] Furthermore, the signal line assembly 60 also includes an angle valve signal line 64, one end of which is connected to the electric angle valve 22, and the other end is connected to the power supply line 63.

[0084] Please see Figures 1-8 As shown, this embodiment of the invention also provides a flushing method for a urinal. The urinal includes a urinal body 200, a flushing system 100, and a drain pipe 300. The urinal body 200 is provided with a urine collection tank 203 and a first mounting hole 201. The flushing system 100 includes a foam generator 10, a water outlet assembly 20, a probe assembly 30, a nozzle 40, and a power supply assembly 50. The foam generator 10, the water outlet assembly 20, and the power supply assembly 50 are all disposed within the urinal body 200. The probe assembly 30 is disposed on the urinal body 200 or the nozzle 40. The nozzle 40 is mounted on the first mounting hole 201. The nozzle 40 is provided with a water outlet 4113 and a foam outlet 4114, with the foam outlet 4114 located outside the water outlet 4113. The water outlet assembly 20 includes a water outlet pipe 21 and an electric angle valve 22. The water outlet pipe 21 is connected to the water outlet 4113. The liquid outlet of the foam generator 10 is connected to the foam outlet 4114. The probe assembly 30 is connected to the foam generator 10 and the electric angle valve 22. The power supply assembly 50 is connected to the electric angle valve 22, the probe assembly 30, and the foam generator 10. The drain pipe 300 is installed inside the urinal body 200 and is connected to the urine collection tank 203. The flushing method includes:

[0085] Step S100: The probe assembly 30 receives the sensing information and transmits it to the foam making host 10 and the electric angle valve 22;

[0086] Step S200: The foaming host 10 receives the signal transmitted by the probe assembly 30, and the foaming host 10 produces foam, with thick foam being sprayed out from the foam outlet 4114;

[0087] Step S300: The electric angle valve 22 receives the signal transmitted by the probe assembly 30. After waiting for a first preset time, the electric angle valve 22 is half-open and remains open for a second preset time. A small amount of water flows through the outlet pipe 21 and sprays out from the outlet 4113.

[0088] Step S400: The electric angle valve 22 is fully opened, and a large amount of water flows through the outlet pipe 21 and sprays out from the outlet 4113.

[0089] It should be noted that the first preset time can be the foaming time of the foaming host 10, that is, the electric angle valve 22 is opened after the foaming machine 12 has finished foaming.

[0090] Understandably, when the distance between the outlet end of the foam generator 10 and the foam outlet 4114 is less than the distance between the outlet end of the electric angle valve 22 and the water outlet 4113, for example, when the distance between the outlet end of the electric angle valve 22 and the water outlet 4113 is greater than twice the distance between the outlet end of the foam generator 10 and the foam outlet 4114, the first preset time can be less than the foaming time of the foam generator 10. If the foaming time of the foam generator 10 is short enough, the first preset time can be 0.

[0091] Optionally, the second preset time can be set according to actual needs. In one embodiment, the second preset time is 30 seconds.

[0092] The flushing method for the urinal in this embodiment of the invention includes at least three stages: the first stage is a foam-making stage, the second stage is a small-volume wall-wetting stage, and the third stage is a large-volume flushing stage. These three stages complete the flushing of the urinal body 200, improving the flushing effect, keeping the ceramic inner wall clean, and preventing stain accumulation and yellowing. In the foam-making stage, thick foam is formed and sprayed from the foam outlet 4114, ultimately forming accumulated foam in the urine collection tank 203. This foam accumulation in the urine collection tank 203 is to allow the water droplet in the small-volume wall-wetting stage to disperse and dilute the foam, ultimately forming a foam shield, which facilitates subsequent flushing. During the process, sewage is less likely to splash out; in the small water volume wall-wetting stage, the half-open electric angle valve 22 reduces the water volume, which not only wets the wall but also saves water. The small water flow impacts the accumulated foam, diluting it and causing it to float on the surface of the sediment to form a foam shield. The water flow also has a sterilizing and washing effect on the urine collection tank 203 when it impacts the accumulated foam. In the large water volume flushing stage, the fully open electric angle valve 22 maximizes the water volume. The large water flow washes the urine collection tank 203 and the inner wall of the urinal body 200, washing away stains and removing odors. Moreover, the impact of the large water flow on the accumulated foam also has a secondary sterilizing and washing effect on the urine collection tank 203.
