The first light guide post and the second light guide post are used to guide the light source emitted by the first light-emitting component through the water flow to be measured to the photosensitive component.

3. The turbidity sensor of claim 2, wherein, The first light guide post includes a first reflective surface, a second reflective surface, and a first column. The first reflective surface and the second reflective surface are respectively disposed at opposite ends of the first column. The second light guide post includes a third reflective surface, a fourth reflective surface, and a second column. The third reflective surface and the fourth reflective surface are respectively disposed at opposite ends of the second column. The first reflective surface is used to reflect the light source emitted by the first light-emitting component into the second reflective surface within the first column. The second reflective surface is used to reflect the light source reflected by the first reflective surface through the measured water flow into the third reflective surface. The third reflective surface is used to reflect the light source reflected by the second reflective surface into the fourth reflective surface within the second column. The fourth reflective surface is used to reflect the light source reflected by the third reflective surface into the photosensitive component.

4. The turbidity sensor of claim 3, wherein The light guide assembly further includes a third light guide post, which is disposed on the side of the base on which the first light-emitting component is located. The third light guide post is used to guide the light source emitted by the second light-emitting component to the photosensitive component.

5. The turbidity sensor of claim 4, wherein, The third light guide post includes a fifth reflective surface, a sixth reflective surface, and a third column. The second light guide post also includes a seventh reflective surface, which is located on the side of the second column away from the third column. The fifth reflective surface and the sixth reflective surface are located at opposite ends of the third column. The fifth reflective surface is used to reflect the light source emitted by the second light-emitting component into the third column and onto the sixth reflective surface. The sixth reflective surface is used to reflect the light source reflected by the fifth reflective surface into the seventh reflective surface. The seventh reflective surface is used to reflect the light source reflected by the sixth reflective surface into the photosensitive component.

6. The turbidity sensor of claim 3, wherein, The base has a first limiting part and a second limiting part on the side where the first light-emitting component is located. The outer wall of the first column is engaged with the base through the first limiting part, and the outer wall of the second column is engaged with the base through the second limiting part.

7. The turbidity sensor of claim 2, wherein, It also includes a housing, in which the base, the first light-emitting component, the second light-emitting component, the photosensitive component, and the light-guiding component are all disposed.

8. The turbidity sensor of claim 7, wherein, The outer shell has a first protrusion and a second protrusion. The first light guide post is disposed in the first protrusion and the second light guide post is disposed in the second protrusion. Both the first protrusion and the second protrusion are light-transmitting structures. The first protrusion and the second protrusion are used to contact the water flow being measured.

9. The turbidity sensor of claim 7, wherein, The outer side wall of the housing is provided with a third protrusion, and the third protrusion is provided with a mounting hole for fixing to the washing machine by bolt structure.

10. A laundry machine characterized by include: The turbidity sensor according to any one of claims 1 to 9.
