[0054] As Figures 1-4 shown, the embodiment provides a water softener, the water softener includes a salt amount sensor 100.

[0055] The salt amount sensor 100 includes a framework 200, a shield 300, a laser sensor 400 and a reset device 500, the laser sensor 400 is fixed to the framework 200, the laser sensor 400 is used to emit laser beam, the shield 300 is rotationally connected to the framework 200, the framework 200 is provided with an opening 210, and the emission end of the laser sensor 400 faces the opening 210, so that the laser beam emitted by the laser sensor 400 can be emitted from the opening 210.

[0056] As Figure 3 and Figure 4 shown, the shield 300 is arranged to be capable of rotating along a first direction x to a first position under the gravity of salt to shield the opening 210, and the reset device 500 is used to apply an acting force to the shield 300 along a second direction y to a second position to open the opening 210, and the first direction x and the second direction y are two opposite directions.

[0057] The shielding piece 300 can rotate its position according to the change of the salt amount. When the salt amount is higher than the preset position, the gravity of the salt can be transmitted to the shielding piece 300, and the shielding piece 300 rotates along the first direction x towards the first position under the action of the gravity of the salt to shield the opening 210, and further shield the laser beam emitted by the laser sensor 400. When the salt amount is lower than the preset position, the shielding piece 300 rotates along the second direction y towards the second position under the action of the reset device 500 to open the opening 210, and further make the shielding piece 300 not shield the laser beam emitted by the laser sensor 400. By setting the shielding piece 300 to change the salt amount into the position change of the shielding piece 300, and further shield the laser emitted by the laser sensor 400 through the position change of the shielding piece 300, the salt amount change is more sensitive to the sensing, the detection result is more accurate, and the problem of false reporting of the salt amount is avoided.

When the gravity of the salt can be transmitted to the salt amount contact part 310, the gravity of the salt drives the salt amount contact part 310 to rotate, and further drives the shielding part 320 arranged on the side of the salt amount contact part 310 to rotate, so that the shielding part 320 shields the opening 210 arranged on the side of the framework 200, and the laser beam irradiated towards the opening 210 is shielded.

[0059] The upper end of the shielding piece 300 is rotationally connected to the framework 200, the upper end of the shielding piece 300 is provided with a rotating shaft 340, the framework 200 is provided with a mounting hole 270, the rotating shaft 340 is rotationally connected in the mounting hole 270, and the salt amount contact part 310 extends obliquely downward to the outside of the framework 200. When the shielding piece 300 is stressed, the shielding piece 300 can rotate with the upper end of the shielding piece 300 as the center. By arranging the salt amount contact part 310 to extend obliquely downward to the outside of the framework 200, it is more convenient for the gravity of the salt to be transmitted to the salt amount contact part 310. When the salt amount contact part 310 is subjected to the gravity of the salt, the salt amount contact part 310 can rotate downward with the upper end of the shielding piece 300 as the center, and further shield the opening 210.

[0060] In the embodiment, the shielding part 320 is fan-shaped, so that the shielding piece 300 is more convenient to rotate. In other embodiments, other shapes of the shielding part 320 considered suitable by those skilled in the art can also be selected.

In other embodiments, those skilled in the art can select a suitable arrangement position of the counterweight 330 according to actual needs.

[0064] As shown in the figure, the framework 200 is provided with a fixed buckle 220, and the laser sensor 400 is fixed to the fixed buckle 220. By arranging the fixed buckle 220 on the framework 200, the laser sensor 400 is fixed on the fixed buckle 220, so that the laser sensor 400 is fixed on the framework 200, and the emitting end of the laser sensor 400 is directed towards the opening 210.

In other embodiments, those skilled in the art can also select the arrangement position of the through hole 250 according to actual needs.​​

[0068] A plurality of water passing holes 260 are arranged on one of the side plates 240 of the skeleton 200, and the water passing holes 260 pass through the side plate 240. By arranging a plurality of water passing holes 260 passing through the side plate 240 on the side plate 240 of the skeleton 200, water can enter the skeleton 200, so that even if a few salt particles enter the skeleton 200, they can be quickly dissolved by water, avoiding interference with the detection structure.

[0069] The salt amount sensor 100 further comprises a fixing member 600 for fixing the salt amount sensor 100 in the water softener, one end of the fixing member 600 is connected to the skeleton 200, the other end of the fixing member 600 is connected to the inside of the water softener, and the end of the fixing member 600 away from the skeleton 200 is arc-shaped, so as to be more matched with the cylindrical support inside the water softener, and the salt amount sensor 100 is more convenient to connect to the inside of the water softener.
