[0044] Referring to Figure 1 , Figure 1 A structure diagram of a cleaning device in an embodiment of the present application is shown. The cleaning device 1000 provided in the embodiment of the present application comprises a cleaning mechanism 1100, the cleaning mechanism 1100 comprising a connecting piece 1110, an eye-washing nozzle 1120, a cleaning pipe 1130, a connecting pipe 1140, a first valve 1150, and a second valve 1160. The connecting piece 1110 comprises a liquid-containing cavity (not shown in the figure) and a liquid inlet hole (not shown in the figure) in communication with the liquid-containing cavity. The connecting pipe 1140 is located between the connecting piece 1110 and the eye-washing nozzle 1120. The liquid inlet of the connecting pipe 1140 is in communication with the liquid-containing cavity, and the liquid outlet of the connecting pipe 1140 is in communication with the eye-washing nozzle 1120. The liquid inlet of the cleaning pipe 1130 is in communication with the liquid-containing cavity. The first valve 1150 is arranged on the connecting pipe 1140, and the second valve 1160 is arranged on the cleaning pipe 1130.

[0045] In the embodiment, the liquid inlet hole is in communication with a water tank (not shown) outside. The cleaning liquid in the water tank enters the liquid-containing cavity through the liquid inlet hole. When the chemical liquid splashes to the eyes of the worker, the worker aims the eyes at the spraying direction of the eye-washing nozzle 1120, opens the first valve 1150, and turns on the connecting pipe 1140. The cleaning liquid in the liquid-containing cavity enters the connecting pipe 1140 from the liquid inlet of the connecting pipe 1140. The cleaning liquid in the connecting pipe 1140 enters the eye-washing nozzle 1120 from the liquid outlet of the connecting pipe 1140. The eye-washing nozzle 1120 sprays the cleaning liquid. The sprayed cleaning liquid flushes the chemical liquid on the eyes of the worker. When the chemical liquid splashes to other areas of the worker except the eyes, the worker opens the second valve 1160, turns on the cleaning pipe 1130, and makes the liquid outlet of the cleaning pipe 1130 face the area splashed with the chemical liquid. The cleaning liquid in the liquid-containing cavity enters the cleaning pipe 1130 from the liquid inlet of the cleaning pipe 1130. The cleaning liquid in the cleaning pipe 1130 flows out from the liquid outlet of the cleaning pipe 1130 to flush the chemical liquid. Since the eye-washing nozzle 1120 and the cleaning pipe 1130 are both connected to the connecting piece 1110, the eye-washing nozzle 1120 and the cleaning pipe 1130 are integrated together through the connecting piece 1110. Therefore, the volume of the cleaning device 1000 in the embodiment can be smaller, and the eye-washing nozzle 1120 and the cleaning pipe 1130 can be arranged simultaneously in a smaller space.

[0046] In summary, the cleaning device 1000 in the embodiment includes the liquid containing cavity through the connecting piece 1110, the liquid inlet of the connecting pipe 1140 communicates with the liquid containing cavity, the liquid outlet of the connecting pipe 1140 communicates with the eye washing nozzle 1120, and the liquid inlet of the cleaning pipe 1130 communicates with the liquid containing cavity, so that the eye washing nozzle 1120 and the cleaning pipe 1130 are integrated together, thereby facilitating the staff to arrange the eye washing nozzle 1120 and the cleaning pipe 1130 in a smaller space at the same time.

[0047] Please continue to refer to Figure 1 In some embodiments, the cleaning mechanism 1100 includes two connecting pipes 1140 and two eye washing nozzles 1120, the two eye washing nozzles 1120 are located on opposite sides of the connecting piece 1110, the two eye washing nozzles 1120 are correspondingly arranged with the two connecting pipes 1140, each connecting pipe 1140 is located between the corresponding eye washing nozzle 1120 and the connecting piece 1110, and the cleaning mechanism 1100 includes two first valves 1150, the two first valves 1150 are correspondingly arranged with the two connecting pipes 1140, and each first valve 1150 is arranged on the corresponding connecting pipe 1140.

[0048] In the embodiment, when the chemical liquid is splashed to the eyes of the staff, the staff aims the two eyes at the spraying directions of the two eye washing nozzles 1120 one by one, opens the two first valves 1150, and conducts the two connecting pipes 1140, so that the cleaning liquid in the liquid containing cavity enters the connecting pipe 1140 through the liquid inlet of each connecting pipe 1140, enters the corresponding eye washing nozzle 1120 from the liquid outlet of the connecting pipe 1140 after entering the connecting pipe 1140, and the eye washing nozzle 1120 sprays the cleaning liquid, and the sprayed cleaning liquid flushes the chemical liquid located at the eyes of the staff.

[0049] Please continue to refer to Figure 1 In some embodiments, the cleaning device 1000 includes a liquid inlet pipe 1200, an electric control valve 1300, a sensor (not marked in the figure) and a controller (not shown), the liquid inlet pipe 1200 includes a first liquid inlet pipe section 1210 and a second liquid inlet pipe section 1220, the liquid outlet of the first liquid inlet pipe section 1210 communicates with the liquid inlet of the electric control valve 1300, the liquid inlet of the second liquid inlet pipe section 1220 communicates with the liquid outlet of the electric control valve 1300, the liquid outlet of the second liquid inlet pipe section 1220 communicates with the liquid inlet hole, the connecting piece 1110 and the cleaning pipe 1130 are both provided with the sensor, and the sensor and the electric control valve 1300 are both in communication connection with the controller.

[0050] In the embodiment, the liquid inlet of the first liquid inlet pipe section 1210 is communicated with the water tank. When the chemical liquid splashes to the eyes of the worker, the worker aims the eyes at the spraying direction of the eye washing nozzle 1120, opens the first valve 1150, and turns on the connecting pipe 1140. The sensor on the connecting piece 1110 detects the human body information and transmits the detection result to the controller. According to the received information, the controller opens the electric control valve 1300, communicates the first liquid inlet pipe section 1210 with the second liquid inlet pipe section 1220, and the washing liquid in the water tank enters the first liquid inlet pipe section 1210 through the liquid inlet of the first liquid inlet pipe section 1210. The washing liquid in the first liquid inlet pipe section 1210 exits the first liquid inlet pipe section 1210 from the liquid outlet of the first liquid inlet pipe section 1210, enters the electric control valve 1300 through the liquid inlet of the electric control valve 1300, and exits the electric control valve 1300 from the liquid outlet of the electric control valve 1300. Then, the washing liquid enters the second liquid inlet pipe section 1220 from the liquid inlet of the second liquid inlet pipe section 1220, exits the second liquid inlet pipe section 1220 from the liquid outlet of the second liquid inlet pipe section 1220, and finally enters the liquid containing cavity through the liquid inlet hole. The washing liquid in the liquid containing cavity enters the connecting pipe 1140 from the liquid inlet of the connecting pipe 1140, enters the eye washing nozzle 1120 through the liquid outlet of the connecting pipe 1140, and is sprayed out of the eye washing nozzle 1120. The sprayed washing liquid flushes the chemical liquid on the eyes of the worker.

[0051] It should be noted that since the connecting pipe 1140 is provided with the first valve 1150, the first valve 1150 can turn on or cut off the connecting pipe 1140. Therefore, when the eyes of the worker are not aimed at the spraying direction of the eye washing nozzle 1120 and the electric control valve 1300 is always in the open state due to the failure of the sensor on the connecting piece 1110, the worker can manually adjust the first valve 1150 to cut off the connecting pipe 1140, so as to isolate the path between the liquid containing cavity and the eye washing nozzle 1120, prevent the eye washing nozzle 1120 from continuously spraying the washing liquid, and ensure the safe operation of the washing equipment 1000.

[0052] In addition, when the chemical liquid is splashed to the area of the worker other than the eyes, the worker aligns the area of the body splashed with the chemical liquid to the liquid outlet of the cleaning pipe 1130, opens the second valve 1160, and turns on the cleaning pipe 1130. The sensor on the cleaning pipe 1130 detects the human body information and transmits the detection result to the controller. According to the received information, the controller opens the electric control valve 1300, connects the first liquid inlet pipe section 1210 and the second liquid inlet pipe section 1220, and the cleaning liquid in the water tank enters the first liquid inlet pipe section 1210 through the liquid inlet of the first liquid inlet pipe section 1210. The cleaning liquid in the first liquid inlet pipe section 1210 exits the first liquid inlet pipe section 1210 from the liquid outlet of the first liquid inlet pipe section 1210, enters the electric control valve 1300 through the liquid inlet of the electric control valve 1300, and exits the electric control valve 1300 from the liquid outlet of the electric control valve 1300. Then, the cleaning liquid enters the second liquid inlet pipe section 1220 from the liquid inlet of the second liquid inlet pipe section 1220, exits the second liquid inlet pipe section 1220 from the liquid outlet of the second liquid inlet pipe section 1220, and finally enters the liquid containing cavity through the liquid inlet hole. The cleaning liquid in the liquid containing cavity enters the cleaning pipe 1130 from the liquid inlet of the cleaning pipe 1130, and flows out of the cleaning pipe 1130 from the liquid outlet of the cleaning pipe 1130 to flush the chemical liquid on the human body.

[0053] It should be noted that since the second valve 1160 is arranged on the cleaning pipe 1130, the second valve 1160 can turn on or cut off the cleaning pipe 1130. Therefore, when the area of the worker's body splashed with the chemical liquid is not aligned with the liquid outlet of the cleaning pipe 1130, and the electric control valve 1300 is always in the open state due to the failure of the sensor on the cleaning pipe 1130, the worker can manually adjust the second valve 1160 to cut off the cleaning pipe 1130 to prevent the liquid outlet of the cleaning pipe 1130 from continuously spraying the cleaning liquid, and ensure the safe operation of the cleaning device 1000.

[0054] Please continue to refer to Figure 1 In some embodiments, the cleaning device 1000 includes an adjusting valve 1400, which includes a first liquid inlet (not labeled in the figure), a first liquid outlet (not labeled in the figure), and a second liquid outlet (not labeled in the figure). The liquid outlet of the first liquid inlet pipe section 1210 is connected to the first liquid inlet, the liquid inlet of the second liquid inlet pipe section 1220 is connected to the first liquid outlet, and the liquid inlet of the electric control valve 1300 is connected to the second liquid outlet. The adjusting valve 1400 is configured such that when the first liquid outlet is turned on, the second liquid outlet is closed; and when the second liquid outlet is turned on, the first liquid outlet is closed.

[0055] When the electric control valve 1300 is in normal operation, the worker manually operates the adjusting valve 1400 to make the first outlet liquid port closed and the second outlet liquid port open. The cleaning liquid in the water tank enters the first inlet liquid pipe section 1210 through the inlet liquid port of the first inlet liquid pipe section 1210. The cleaning liquid in the first inlet liquid pipe section 1210 exits the first inlet liquid pipe section 1210 through the outlet liquid port of the first inlet liquid pipe section 1210 and enters the adjusting valve 1400 through the first inlet liquid port. The cleaning liquid in the adjusting valve 1400 exits the adjusting valve 1400 through the second outlet liquid port and enters the electric control valve 1300 through the inlet liquid port of the electric control valve 1300. The cleaning liquid in the electric control valve 1300 exits the electric control valve 1300 through the outlet liquid port of the electric control valve 1300 and enters the second inlet liquid pipe section 1220 through the inlet liquid port of the second inlet liquid pipe section 1220. The cleaning liquid in the second inlet liquid pipe section 1220 exits the second inlet liquid pipe section 1220 through the outlet liquid port of the second inlet liquid pipe section 1220 and finally enters the liquid containing cavity through the inlet liquid hole.

[0056] When the electric control valve 1300 is damaged, the worker manually operates the adjusting valve 1400 to make the first outlet liquid port open and the second outlet liquid port closed. The cleaning liquid in the water tank enters the first inlet liquid pipe section 1210 through the inlet liquid port of the first inlet liquid pipe section 1210. The cleaning liquid in the first inlet liquid pipe section 1210 exits the first inlet liquid pipe section 1210 through the outlet liquid port of the first inlet liquid pipe section 1210 and enters the adjusting valve 1400 through the first inlet liquid port. The cleaning liquid in the adjusting valve 1400 exits the adjusting valve 1400 through the first outlet liquid port and enters the second inlet liquid pipe section 1220 through the inlet liquid port of the second inlet liquid pipe section 1220. The cleaning liquid in the second inlet liquid pipe section 1220 exits the second inlet liquid pipe section 1220 through the outlet liquid port of the second inlet liquid pipe section 1220 and finally enters the liquid containing cavity through the inlet liquid hole.

[0057] In summary, the cleaning device 1000 in the embodiment can still work normally even if the electric control valve 1300 is damaged, because the adjusting valve 1400 is arranged. The safety of the cleaning device 1000 is high.

[0058] It should be noted that the adjusting valve 1400 can be a three-way valve.

[0059] In some embodiments, the cleaning device 1000 comprises a third valve (not shown in the figure). The inlet liquid port of the third valve is in communication with the outlet liquid port of the electric control valve 1300. The outlet liquid port of the third valve is in communication with the inlet liquid port of the second inlet liquid pipe section 1220.

[0060] In the embodiment, the third valve is arranged to prevent the first liquid outlet from being connected, and when the second liquid outlet is closed, the cleaning liquid in the second liquid inlet pipe section 1220 flows back into the electric control valve 1300 through the liquid inlet of the electric control valve 1300 and the liquid outlet of the electric control valve 1300.

[0061] Please continue to refer to Figure 1 In some embodiments, the cleaning device 1000 comprises a water collecting member 1500, and the cleaning mechanism 1100 and the water collecting member 1500 are arranged along the gravity direction of the water collecting member 1500.

[0062] In the embodiment, the cleaning liquid sprayed by the eye washing nozzle 1120 and the cleaning pipe 1130 falls into the water collecting cavity 1510 of the water collecting member 1500 under the action of gravity after washing the chemical liquid, and is collected by the water collecting cavity 1510. By arranging the water collecting cavity 1510, the cleaning liquid can be prevented from splashing to the ground and polluting the ground.

[0063] Please continue to refer to Figure 1 In some embodiments, the liquid outlet of the cleaning pipe 1130 is directed towards the water collecting cavity 1510.

[0064] In the embodiment, by arranging the liquid outlet of the cleaning pipe 1130 to be directed towards the water collecting cavity 1510, most of the cleaning liquid sprayed through the liquid outlet of the cleaning pipe 1130 can be collected by the water collecting cavity 1510.

[0065] In some embodiments, the connecting member 1110 and the water collecting member 1500 are arranged along the gravity direction of the water collecting member 1500, the water collecting member 1500 is provided with a water collecting cavity 1510 on the side close to the connecting member 1110, the cleaning pipe 1130 is located between the connecting member 1110 and the water collecting member 1500, and the cleaning pipe 1130 extends along the gravity direction of the water collecting member 1500.

[0066] In some embodiments, the two eye washing nozzles 1120 are located on opposite sides of the connecting member 1110 along a first direction, and the first direction is perpendicular to the gravity direction of the water collecting member 1500.
