As shown in fig. 1, when a user needs to take water, for example, the valve body 10 is moved from the second position (a position where the seal 102 blocks the one end opening of the third passage 2023) to the first position (a position where the seal 102 blocks the one end opening of the first passage 2021), the second passage 2022 is in communication with the third passage 2023, and water can be discharged from the other end of the third passage 2023; when the user finishes taking water, the valve body 10 is moved from the first position (the position where the seal 102 closes the one end opening of the first passage 2021) to the second position (the position where the seal 102 closes the one end opening of the third passage 2023), the second passage 2022 is in communication with the first passage 2021, and water can be discharged from the other end of the first passage 2021.

In a specific example, the second passage 2022 is a water inlet passage, the first passage 2021 is a normally open passage, for example, the first passage 2021 may be communicated with a water tank, and water in the second passage 2022 may return to the water tank through the first passage 2021 to achieve the effects of pressure relief, sterilization, backflow, and the like; the third passage 2023 may be a normally closed passage that communicates with the second passage 2022 only when a user water intake demand is received.

According to some embodiments of the present utility model, as shown in fig. 1, the second passage 2022 is located between the first passage 2021 and the third passage 2023, the driving assembly 205 is located on a side of the first passage 2021 away from the second passage 2022, and one end opening of the first passage 2021 and one end opening of the third passage 2023 face two ends of the extending direction of the second passage 2012 respectively, and when the sealing member 102 moves along the extending direction of the second passage 2012, one end opening of the first passage 2021 and one end opening of the third passage 2023 may be blocked.
