[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1, as Figure 1 to Figure 5 As shown, the automatic salt adding device in this embodiment includes an upper shell 1, an exciter 3, a lower shell 2, a mesh plate 43 and a motor 4. The upper shell 1 has a salt storage chamber 11 and a mounting area 12. The bottom of the salt storage chamber 11 has a plurality of through holes 14. A cover plate 13 is provided on the port of the upper shell. When salt is lacking, the cover plate 13 is opened and salt is added, mainly sodium carbonate. The upper shell 1 and the lower shell 2 constitute a housing 10.

[0027] The exciter 3 is arranged in the installation area 12 of the upper shell 1 ; the lower shell 2 is assembled below the upper shell 1 , and the inner cavity forms a brine preparation chamber 2 a . The lower shell 2 has a water inlet port 21 and a water outlet port 22 .

[0028] The mesh plate 43 is movably arranged on the bottom of the salt storage chamber 11 and has a plurality of mesh holes 44. The mesh holes 44 cooperate with the through holes 14 to enable the salt in the salt storage chamber 11 to pass through the through holes 14 and the mesh holes 44 in sequence and then fall into the brine preparation chamber 2a. In this embodiment, the mesh holes 44 and the through holes 14 are circular holes of the same diameter. When they are completely staggered, the salt addition is closed, and when they are completely aligned, the salt addition is opened.

[0029] The motor 4 is disposed in the mounting area 12 of the upper housing 1 and can drive the mesh plate 43 to move. Figure 4 As shown, a gear 41 is provided at the power output end of the motor 4 , and correspondingly, a rack 42 meshing with the gear 41 is provided at one side of the mesh plate 43 .

[0030] A salinity sensor linked to the vibrator 3 and the motor 4 is provided in the lower housing 2. Specifically, a limit channel 23 is provided in the salt water preparation chamber 2a, and a small hole 24 is provided at the bottom of the limit channel 23 to communicate with the salt water preparation chamber 2a. The salinity sensor in this embodiment includes a Hall sensor 51 provided on one side of the lower housing 2 and a float 52 provided in the limit channel 23, and a magnet that can cooperate with the Hall sensor 51 to detect the salt concentration is provided in the float 52. The Hall sensor 51 detects the change in the magnetic field to determine the height of the float 52. An end cover 25 is provided at the top of the limit channel 23 to limit the float from rushing out of the limit channel 23.

[0031] The automatic salt dosing plan is as follows: For the first time after being transported to the user's home, just press the power button to automatically inject 500ml of pure water. At the same time, the motor starts, driving the gear to rotate, and the gear drives the rack to move the screen, so that the mesh and the through hole are aligned. At this time, the vibrator is turned on, and the sodium carbonate powder will fall into the brine preparation chamber below through the through hole and the mesh with the vibration. The float will slowly float up due to the increase in density. When it rises to the position of the Hall sensor, the vibrator stops and the motor drives the screen to return to its initial position. After each electrolysis, the mass of sodium carbonate in the water decreases, the density decreases, the float will drop, triggering the Hall sensor, and the motor will automatically start to repeat the above actions.

[0032] In this embodiment, in order to ensure the annual consumption of salt, the total volume of sodium carbonate needs to be 1500 ml, so the size of the device only needs to be 2 L.

[0033] Embodiment 2, the driving mechanism in this embodiment includes a driving source 4a and a telescopic rod 4b provided at the power output end of the driving source 4a, and the telescopic rod 4b is connected to the mesh plate 43. The driving source 4a can drive the telescopic rod 4b to move back and forth. Specifically, one side of the mesh plate 43 has a connecting plate 431 extending laterally, and the outer end of the telescopic rod 4b is fixedly connected to the connecting plate 431. The driving source 4a in this embodiment can be a cylinder or a motor drive module. For other structures, refer to Embodiment 1.
