[0043] Embodiment one

[0044] The embodiment of the present application provides a drainage structure which can be used on any device requiring drainage and can detect the turbidity of the drainage.

[0045] Referring to Figures 1 to 8 , the drainage structure comprises a drainage pipe, a detection assembly 20 and a hollow pipe 30, the drainage pipe comprises a detection section 11, the detection section 11 has a detection position, the detection assembly 20 is arranged opposite to the detection position, and the detection assembly 20 can detect the turbidity of the washing water; the hollow pipe 30 is sleeved on the detection section 11, the hollow pipe 30 is provided with a detection hole 31, and the inner wall of the hollow pipe 30 is provided with cleaning cotton 32; the hollow pipe 30 can move along the detection section 11 so that the cleaning cotton 32 wipes the detection position, and the detection hole 31 can selectively face the detection position.

[0046] When draining, the hollow tube 30 moves so that the cleaning cotton 32 wipes the detection site, and the detection assembly 20 detects the detection site through the detection hole 31 to detect the turbidity of the washing water; after the draining ends, the hollow tube 30 returns to the original position so that the cleaning cotton 32 wipes and shields the detection site again. The cleaning cotton 32 can not only wipe the detection site, but also shield the detection site, prevent dust from accumulating on the detection site, and ensure the accuracy of the detection result of the detection assembly 20.

[0047] The detection assembly 20 can be a light assembly, specifically including a transmitter and a receiver, which are distributed on both sides of the detection section 11. The light emitted by the transmitter is received by the receiver through the detection section 11, and the turbidity of the washing water is determined according to the light transmission degree of the detection section 11. At this time, the detection section 11 needs to be a transparent tube.

[0048] Alternatively, the detection assembly 20 is an electromagnetic wave assembly, specifically including a transmitter and a receiver, which are distributed on both sides of the detection section 11. The electromagnetic wave emitted by the transmitter is received by the receiver through the detection section 11, and the turbidity of the washing water is determined according to the electromagnetic wave transmission degree of the detection section 11.

[0049] Alternatively, the detection assembly 20 is a sound wave assembly, specifically including a transmitter and a receiver, which are distributed on both sides of the detection section 11. The sound wave emitted by the transmitter is received by the receiver through the detection section 11, and the turbidity of the washing water is determined according to the sound wave transmission degree of the detection section 11.

[0050] Two detection holes 31 are arranged on the hollow tube 30 corresponding to each detection site, one detection hole 31 is used to be opposite to the transmitter, and the other detection hole 31 is used to be opposite to the receiver.

[0051] The detection section 11 can be provided with multiple detection sites, and the detection assembly 20 is provided with multiple groups. The multiple groups of detection assemblies 20 are arranged along the axial direction of the detection section 11 to avoid inaccurate detection results caused by the failure of one group of detection assemblies 20.

[0052] The draining structure further includes a shell 40, and the detection assembly 20, the hollow tube 30 and part of the draining pipe are located in the shell 40. The shell 40 plays a protective role to prevent dust from accumulating on the detection section 11 of the draining pipe.

[0053] In the embodiment, the hollow tube 30 can move linearly along the axial direction of the detection section 11.

[0054] The driving part can be arranged to drive the hollow tube 30 to move. The hollow tube 30 has a first position and a second position. During the drainage, the driving part is controlled to drive the hollow tube 30 to move from the first position to the second position, and at the end of the drainage, the driving part is controlled to drive the hollow tube 30 to move from the second position to the first position, or the hollow tube 30 is driven by a reset member to move from the second position to the first position.

[0055] In the embodiment, the hollow tube 30 is driven to move by the water flow pressure during the drainage, and no additional driving part is needed, thereby saving energy.

[0056] Specifically, the drain pipe further comprises a main pipe section 12, the water inlet of the detection section 11 is communicated with the main pipe section 12, the diameter of the main pipe section 12 is larger than that of the detection section 11, the hollow tube 30 is provided with a mounting disc 33 at one end, the mounting disc 33 is located between the main pipe section 12 and the detection section 11, and the pressure difference between the main pipe section 12 and the detection section 11 during the drainage acts on the mounting disc 33 to drive the hollow tube 30 to move along the axial direction of the detection section 11, and the end of the hollow tube 30 away from the main pipe section 12 is provided with a spring 50.

[0057] Specifically, the pressure difference between the main pipe section 12 and the detection section 11 during the drainage acts on the mounting disc 33 to drive the hollow tube 30 to move along the axial direction of the detection section 11, and the hollow tube 30 moves from the first position to the second position, at which time the spring 50 is compressed, and at the end of the drainage, the pressure acting on the mounting disc 33 disappears, and under the action of the restoring force of the spring 50, the hollow tube 30 moves from the second position to the first position.

[0058] The outer peripheral wall of the mounting disc 33 is sealed with the main pipe section 12 by a first sealing ring 61, and the inner peripheral wall of the mounting disc 33 is sealed with the detection section 11 by a second sealing ring 62, so as to prevent water leakage.

[0059] The outer peripheral surface of the detection section 11 is provided with a first limiting protrusion 111, the inner peripheral surface of the main pipe section 12 is provided with a second limiting protrusion 121, and the mounting disc 33 is located between the first limiting protrusion 111 and the second limiting protrusion 121. The first limiting protrusion 111 and the second limiting protrusion 121 limit the hollow tube 30, so as to prevent the hollow tube 30 from being separated from the detection section 11.

[0060] The outer peripheral surface of the detection section 11 is provided with a third limiting protrusion 112, the end of the hollow tube 30 is provided with a fourth limiting protrusion 34, and the spring 50 is sleeved on the detection section 11 and located between the third limiting protrusion 112 and the fourth limiting protrusion 34. The third limiting protrusion 112 and the fourth limiting protrusion 34 limit the spring 50.

[0061] When draining, the pressure difference between the main pipe section 12 and the detection section 11 drives the installation disc 33 to drive the hollow pipe 30 to move from the first position to the second position, and the cleaning cotton 32 wipes the detection position in the moving process. When the hollow pipe 30 is in the second position, the detection hole 31 is opposite to the detection position, and the detection assembly 20 detects the detection position through the detection hole 31 to detect the turbidity of the washing water.

[0062] After the draining is finished, the hollow pipe 30 moves from the second position to the first position under the restoring force of the spring 50, and the cleaning cotton 32 wipes the detection position again in the moving process. When the hollow pipe 30 is in the first position, the cleaning cotton 32 on the hollow pipe 30 blocks the detection position and the detection hole 31 deviates from the detection position.

[0063] Embodiment Two

[0064] For the sake of simplicity, only the difference between Embodiment Two and Embodiment One is described. The difference is that the hollow pipe 30 can rotate around the axis of the detection section 11.

[0065] A driving part can be arranged to drive the hollow pipe 30 to rotate. The hollow pipe 30 has a first position and a second position. When draining, the driving part is controlled to drive the hollow pipe 30 to rotate from the first position to the second position. When the draining is finished, the driving part is controlled to drive the hollow pipe 30 to rotate from the second position to the first position, or the hollow pipe 30 is driven to rotate from the second position to the first position by a reset member. The reset member can be a torsion spring.

[0067] When draining, the hollow pipe 30 moves from the first position to the second position, and the cleaning cotton 32 wipes the detection position in the moving process. When the hollow pipe 30 is in the second position, the detection hole 31 is opposite to the detection position, and the detection assembly 20 detects the detection position through the detection hole 31 to detect the turbidity of the washing water.

[0068] After the draining is finished, the hollow pipe 30 moves from the second position to the first position, and the cleaning cotton 32 wipes the detection position again in the moving process. When the hollow pipe 30 is in the first position, the cleaning cotton 32 on the hollow pipe 30 blocks the detection position and the detection hole 31 deviates from the detection position.
