[0030] Reference Figures 1 to 6 A water softening device for a water softener includes: a salt tank assembly 1, a salt box 2 inside the salt tank assembly 1, a salt valve 3 inside the salt tank assembly 1, and a water flow channel 4 located below the salt tank assembly 1, the water flow channel 4 being connected to the salt box 2 and the salt valve 3. In use, water flows through the salt valve 3, through the water flow channel 4, and into the salt box 2 for filtration, thereby achieving the water softening function.

[0031] In a preferred embodiment, the salt box 2 is detachably connected to the salt container 1. This facilitates the removal of the salt box 2 for cleaning and salt draining.

[0032] In a preferred embodiment, the water flow channel 4 is snapped onto the salt tank assembly 1, and the salt box 2 is connected to the salt tank assembly 1. The salt box 2 is equipped with a one-way check valve 21. When the salt box 2 is removed from the salt tank assembly 1, the one-way check valve 21 returns to its original position, blocking the connection and preventing water from flowing out of the salt box 2. When the salt box 2 is installed, the one-way check valve 21 spring abuts against the water flow channel 4, and the one-way check valve 21 opens to achieve connection.

[0033] As a preferred embodiment, refer to Figure 3 The salt valve 3 includes a float valve core 322 and an exhaust channel 323. The float valve core 322 is located below the salt tank assembly 1, and the exhaust channel 323 is located on one side of the float valve core 322. The bottom of the exhaust channel 323 is connected to the atmosphere. The salt valve 3 includes a valve cover 31, which has an inlet and outlet 321. A valve core inlet 324 is located at the bottom of the salt valve 3. The exhaust channel 323 removes air from the bottom of the salt valve 3. Due to the low position of the water flow channel 4 and the salt valve 3, the water can be completely drained, resulting in high efficiency.

[0034] In a preferred embodiment, a water heater 5 is also included, which has an inlet / outlet 51 connected to an outlet / inlet 321. When the water heater 5 provides positive pressure, water enters the salt valve 3 through the inlet / outlet 321, and then flows through the water flow channel 4 into the salt box 2 for purification. When the water heater 5 provides negative pressure, the purified water flows from the salt box 2 into the water heater 5.

[0035] In a preferred embodiment, the salt valve 3 further includes a salt valve seat 313, on which a salt suction straight pipe 33 is provided, and a quick-connect connector 32 is provided at the top of the salt suction straight pipe 33. It also includes a salt valve tank 319, inside which a float tank 311 is provided, and inside the float tank 311 a float 312 is provided. A fiberglass rod 36 is provided at the top of the float tank 311, and a float 38 is fixedly installed on the fiberglass rod 36. The float 38 is connected to the salt suction straight pipe 33. A float cone 315 is welded onto the float tank 311, and a stop cone 317 is snapped into place at the bottom of the float cone 315. A silicone gasket 316 is provided between the salt valve seat 313 and the salt valve tank 319, corresponding to the stop cone 317. A sealing gasket 314 is provided at the bottom of the float tank 311, located below the float 312. A guide rubber 310 is provided at the top of the float tank 311. Water heater 5 is connected to quick-connect fitting 32 via a flexible hose, which in turn connects to salt valve 3. Water flows through quick-connect fitting 32, through salt suction pipe 33, and into salt valve seat 313. As the liquid level rises, it enters salt valve tank 319. As the liquid level continues to rise, float ball 312 floats up, expelling air from the lower part of salt valve 3 through salt valve seat 313, and water flows into salt box 2. As the liquid level in salt box 2 continues to rise, when it reaches approximately half the height of float 38, float 38 floats up, causing fiberglass rod 36 to move upward. The upward movement of fiberglass rod 36 causes float tank 311 to move upward and guide rubber 310 to deform upward. 1. The upward movement causes the stop cone 317 to move upward, and the stop cone 317 moves upward and sticks tightly to the silicone pad 316 to achieve a seal, preventing further water filling and forming a physical structure to protect against water overflow. After water filling is completed, the water and the salt block in the salt box 2 dissolve to form brine. The negative pressure generated by the water heater 5 drives the brine in the salt box 2 to be drawn into the water heater 5 through the salt valve 3. When the liquid level is lower than the float ball 312, the float ball 312 falls down and sticks to the sealing pad 314 to close the exhaust channel 323 to prevent air from being drawn in. The salt valve seat 313 is at the bottom of the entire salt valve 3, which can make the brine fully sucked up, and there will be no residual brine in the salt box 2.

[0036] In a preferred embodiment, the salt valve cover 31 is provided with a fixing member 34 and a first fixing knob 35. The salt suction tube 33 is fixedly connected through the fixing member 34 and the first fixing knob 35. The bottom of the salt suction tube 33 is provided with a second fixing knob 39. The salt suction tube 33 is fixedly connected to the salt valve seat 313 through the second fixing knob 39.

[0037] In a preferred embodiment, the float 38 and the fiberglass rod 36 are fixedly connected by a butterfly fixing clip 37, and the salt valve tank 319 and the salt valve seat 313 are fixed by a pin 320.

[0038] As an alternative embodiment, a filter screen 318 is welded to the bottom of the salt valve seat 313.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
