The pre-filter in this embodiment works as follows:

as shown in fig. 1, when the slider 11 is at the second position, i.e., the first blocking portion 12 blocks the first water passing port 16 and the second blocking portion 13 blocks the second water passing port 17, water flows from the water inlet channel 5, flows through the third water passing channel 10, enters the filtered water inlet channel 2, is filtered by the filter cartridge, enters the water passing cavity 7 from the filtered water outlet channel 3 via the first water passing channel 8, and flows out from the water outlet channel 6, and is in the normal filtering mode. When the filter base 1 needs to be disassembled and washed, as shown in fig. 3, the operating member 19 is pressed to enable the sliding member 11 to move from the second position to the first position along the first direction, at this time, the first blocking part 12 blocks the third water passing channel 10, the second blocking part 13 blocks the first water passing channel 8, water flow enters the second water passing channel 9 from the first water passing port 16 after entering from the water inlet channel 5, then enters the water passing cavity 7 from the second water passing port 17 and then flows out from the water outlet channel 6, and at this time, the filter base 1 can be disassembled and washed without closing a water valve.

The embodiment also provides a water outlet device, which comprises a base body and the pre-filter in the embodiment, wherein the pre-filter is arranged in the base body.

In this embodiment, since the first blocking portion 12 blocks the third water passing channel 10 and the second blocking portion 13 blocks the first water passing channel 8 when the sliding member 11 is in the first position, and the first blocking portion 12 and/or the second blocking portion 13 blocks the second water passing channel 9 when the sliding member 11 is in the second position, the water inlet channel 5 can be switched between the water inlet cavity 7 and the water inlet channel 2, the water valve is not required to be closed when the filter base 1 needs to be disassembled for cleaning, and the filter base 1 can be disassembled only by displacing the sliding member 11 to the first position to block the third water passing channel 10 and the first water passing channel 8, thereby blocking water inlet and outlet to the filter base 1. Compared with the prior art, the sliding plugging mode is adopted to replace the rotary switching mode, so that the arrangement position of the third water passing channel 10 does not need to avoid the water inlet channel 5 on the projection plane perpendicular to the first direction, and a foundation is provided for increasing the flow area of the third water passing channel 10.

In this embodiment, the included angle formed between the two ends formed by the projection of the third water passing channel 10 on the projection plane perpendicular to the first direction and the perpendicular line of the axis of the water passing cavity 7 is greater than 180 degrees, so that the flow area of the third water passing channel 10 is increased, and the water yield in the filtering state is improved compared with the prior art. It should be noted that the included angle in this embodiment is the included angle of the opening facing the water inlet channel.

In this embodiment, the water passing seat 4 is split into the water passing member 14 and the housing 15, so that the processing and manufacturing are facilitated.

In this embodiment, since the projection of the first water passing port 16 and the projection of the third water passing channel 10 on the projection plane at least partially overlap, when the sliding member 11 slides in the first direction between the first position and the second position, the first blocking portion 12 is convenient for blocking the third water passing channel 10 and the first water passing port 16.

In this embodiment, since the second water passing port 17 faces the water passing chamber 7 along the first direction, the second blocking portion 13 facilitates blocking the first water passing channel 8 and the second water passing port 17 when the sliding member 11 slides in the first direction between the first position and the second position.

In this embodiment, by adding the groove 18 adapted to the second blocking portion 13, the blocking effect of the second blocking portion 13 when blocking the second water passing port 17 is improved.

In this embodiment, when the sliding member 11 is in the second position, the first blocking portion 12 and the second blocking portion 13 simultaneously block the second water passing channel 9, thereby improving the blocking effect and avoiding water leakage.

In this embodiment, the operating member 19 is fixedly connected to the sliding member 11 and partially extends out of the water passing seat 4, and this operating mode has a simple structure and is easy to implement.
