In the present embodiment, the hardness dial 64 is used to set the set water amount, which is the water outlet amount of the softened resin tank 6, and specifically, the set water amount is comprehensively considered in accordance with the hardness of the intake water and the capacity of the softened resin tank.
For example, according to the capacity of the softened resin tank 6, X tons of water can be produced at 2eq/L of water hardness, and the gear set 55, the impeller 56 or the nozzle 66 and the measuring disc 59 are adjusted in number of teeth so as to: the X ton water drives the measuring disc 59 to rotate a full circle, so that 4eq/L of incoming water can rotate a half circle, 8eq/L can rotate 1/4 circles, 3eq/L can rotate 2/3 circles, and so on, so that corresponding even full circle values, namely hardness value marks 69, exist in twelve hardness plectrums 64, for example: 2. 3, 4, 5, 6, 8 and 12.
The 2# hardness shifting piece 64 is shifted outwards, so that the hardness shifting piece just breaks away from the pointer 541, the position of the measuring disc 59 is the flow zero point 70, positioning point marks are respectively arranged on the upper cover 52 and the measuring disc 59, for example, two arrows are an arrow of the flow zero point 70 and an arrow of the indicator 81, then according to the flow zero point 70, the flow scale 68 is uniformly marked on the upper cover 52 in the same anticlockwise direction, and the full circle numerical value is X tons.
When the user uses the water dispenser, the user dials the N # hardness dial piece 64 outwards according to the actual incoming water hardness, and dials the other parts inwards, as shown in FIG. 10, the pointer 541 is hidden in the upper cover 52, namely, the water preparation state is achieved. With the water, the metering disc 59 rotates to fig. 11, the N # hardness dial 64 drives the pointer 541 to rotate, the positioning rod 62 is inserted into the regeneration groove 542a, at this time, both the pointer 541 and the positioning portion 543 are exposed, i.e. in a state of needing regeneration, so as to prompt a user that regeneration is needed, and at this time, water can still be supplied. After the portable softening unit 2 is regenerated as described above, the original water consumption point is installed, the metering disc 59 is manually turned counterclockwise to the flow zero point 70 to align, as shown in fig. 12, and then the positioning portion 543 is pressed to return to the water production state, and metering is restarted to wait for the next prompt.
