The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

The faucet and its quantitative water output control device and method according to the embodiment of the present invention will be described below in conjunction with the accompanying drawings.

Fig. 1 is a schematic block diagram of a quantitative water outlet control device for a faucet according to an embodiment of the present invention.

As shown in FIG. 1 , the quantitative water outlet control device of the faucet according to the embodiment of the utility model may include a gear switch 10 , a water outlet valve 20 , a water flow sensor 30 and a control module 40 .

Wherein, the gear switch 10 may have multiple gears, and the gear switch 10 outputs a gear signal by receiving a user instruction. The water flow sensor 30 is used to detect the water output of the water valve 20 . The control module 40 is connected to the gear switch 10, the water outlet valve 20 and the water flow sensor 30 respectively. The control module 40 is used to control the opening or closing of the water outlet valve 20, and obtain the total water output corresponding to the current gear according to the gear signal, and When the total water output of the water outlet valve 20 detected by the water flow sensor 30 reaches the total water output corresponding to the current gear, the water outlet valve 20 is controlled to close.

Specifically, the gear switch 10 can be a rotary mechanical gear switch, which can have multiple gears, and the number of gears can be set according to actual conditions, for example, it can be set to three gears. The total water output corresponding to the first gear is a small water output, the total water output corresponding to the second gear is a medium water output, and the total water output corresponding to the third gear is any water output, that is, if the user does not actively turn the rotation When the mechanical shift switch returns to the closed state, the faucet can always discharge water for users to use. After obtaining the corresponding relationship between each gear and the total water output, the corresponding relationship can be stored in the storage module.

The user command refers to the command issued by the user to manually rotate the gear switch 10 to the corresponding gear according to the actual water consumption, and the gear switch 10 outputs a gear signal after receiving the user command. It can be understood that the user manually rotates the gear switch 10 to different gears to generate different user commands, and the gear switch 10 receives different user commands to generate different gear signals. For example, when the user needs to use a small amount of water, the gear switch 10 can be manually rotated from the off state to the first gear. When the gear switch 10 receives the user instruction corresponding to the first gear, it will output the first gear. The gear signal corresponding to the gear.

The total number of pulses corresponding to the bit, and obtain the current pulse number of the pulse counter, that is, when the gear switch 10 is switched to the second gear, the accumulated pulse number of the first gear is calculated. Subtract the total number of pulses corresponding to switching the second gear from the current number of pulses to calculate the remaining number of pulses. According to the number of remaining pulses, it is possible to calculate the amount of water that needs to be discharged from the water outlet valve 20 . After switching gears, the pulse counter continues to count pulses until the number of pulses counted by the pulse counter reaches the remaining number of pulses, and the control module 40 controls the outlet valve 20 to close.
