DETAILED DESCRIPTION

[0032] In order to further explain the technical scheme of the utility model, the utility model is described in detail below through specific embodiments.

[0033] As Figures 1 to 8As shown, it is a kind of water drainer involved in the utility model, including water draining cylinder 1, inner filter basket 2, bounce core 3, upper filter screen 4, pressing rod 5 and water sealing rubber ring 6;Water draining cylinder 1 can be inserted into the water inlet of water tank.The water draining cylinder 1 is provided with water passing support 11, the middle part of water passing support 11 is formed with mounting hole 111, and the inner filter basket 2 is placed in the water draining cylinder 1 above water passing support 11;The lower end of the inner filter basket 2 is formed with positioning cylinder 23 for being detachably inserted into mounting hole 111, and the middle part of positioning cylinder 23 is formed with positioning hole 231;The bounce core 3 has lower fixed part 31 and upper movable part 32 capable of axial relative movement.

[0034] The lower end of the lower fixed part 31 of the bounce core 3 is detachably inserted into the positioning hole 231;Upper filter screen 4 is placed in the upper opening 12 of the water draining cylinder 1, the pressing rod 5 is movably arranged through the upper filter screen 4, and the lower end of the pressing rod 5 is detachably inserted into and connected with the upper end of the upper movable part 32 of the bounce core 3;The water sealing rubber ring 6 is located between the upper filter screen 4 and the inner filter basket 2, and the water sealing rubber ring 6 is installed on the outer side wall of the upper movable part 32 or the outer side wall of the pressing rod 5;With the axial height state change of the upper movable part 32 relative to the lower fixed part 31, the water sealing rubber ring 6 opens or blocks the upper opening 12 of the water draining cylinder 1.

[0035] In this way, the upper filter screen 4 and the inner filter basket 2 of the water drainer involved in the utility model can cooperate to filter, and the filtering effect on sundries is improved: by inserting the positioning cylinder 23 at the lower end of the inner filter basket 2 into the mounting hole 111 of the water passing support 11 and inserting the lower end of the bounce core 3 into the positioning hole 231 in the positioning cylinder 23, the installation and positioning of the inner filter cylinder and the bounce core 3 are realized at the same time, and in use, in addition to the pressing rod 5 and the upper filter screen 4 being separable from the bounce core 3 for cleaning, the bounce core 3 and the inner filter basket 2 can also be taken out of the water draining cylinder 1 and separated from each other for cleaning.

[0036] As a preferred embodiment of the present application, the pressing rod 5 is formed with mounting groove 51, and the water sealing rubber ring 6 is installed in the mounting groove 51.The water sealing rubber ring 6 is arranged on the pressing rod 5, so that the height of the water sealing rubber ring 6 in the water draining cylinder 1 is increased, so that when the bounce core 3 is in a high position, a larger drainage gap can be generated between the water sealing rubber ring 6 and the water draining cylinder 1.

[0037] Preferably, the lower end of the pressing rod 5 is formed with limiting ring 52, and the diameter of the limiting ring 52 is greater than the inner hole diameter of the upper filter screen 4 for the pressing rod 5 to pass through.The limiting ring 52 can prevent the water sealing rubber ring 6 from falling off.

[0038] If the water sealing rubber ring 6 is arranged on the upper movable part 32 of the bouncing core 3, the limiting ring 52 can also be used to support the upper filter screen 4, so that the upper filter screen 4 can be lifted after the pressing rod 5 is separated from the upper movable part 32.

[0039] Preferably, the upper end of the pressing rod 5 is provided with a cap 53 which is threadedly mounted on the upper end of the pressing rod 5; the diameter of the cap 53 is greater than the inner diameter of the inner hole of the upper filter screen 4 through which the pressing rod 5 passes.
