Through set up sealed pad at filter 6 upper and lower both ends, when apron 3 and can dismantle inner panel 4 all install on water outlet 2, the upper and lower both ends of filter 6 are through sealed pad with sleeve 5 bottom and can dismantle inner panel 4 contact respectively, play sealed effect.
In one embodiment of the invention, the cover plate 3 and the removable inner plate 4 are provided with a concealable handle 19 on their surfaces. Referring to fig. 5, in particular, arc-shaped grooves 18 are formed on the surfaces of the cover plate 3 and the detachable inner plate 4, and arc-shaped handles 19 are rotatably mounted in the arc-shaped grooves 18. Under normal condition, handle 19 is hidden in arc wall 18, when needs dismantlement or installation apron 3 or can dismantle inner panel 4, rotate out handle 19 by arc wall 18 in, and then through rotating handle 19 along apron 3 circumferencial direction, can accomplish the dismouting.
A water flow blocking assembly is arranged in the water inlet part 1. The water flow shut off assembly comprises a shut off panel 10, a blocking block 13, a driving member, etc. The partition plate 10 is circular and is rotatably installed in the water inlet portion 1. The blocking piece 13 is oval, and the outer wall is fixedly connected with the inner wall of the water inlet part 1. The side wall of the blocking piece 13 is provided with a waterproof ring. The driving member is used for driving the partition plate 10 to rotate in the water inlet part 1.
Wherein, when the water inlet part 1 is in a water flow blocking state, the blocking plate 10 is contacted with the blocking block 13. When the water inlet part 1 is in a water flow state, the partition plate 10 is parallel to the detachable inner plate 4.
When the water inlet valve is in a water flow state, water normally enters the water outlet part 2 from the water inlet part 1, and when the water flow is required to be switched to a water flow blocking state, the driving piece is used for driving the partition plate 10 to rotate until the end wall of the partition plate 10 is contacted with the sealing ring 20 on the blocking block 13, so that the water flow is blocked.
In an embodiment of the present invention, referring to fig. 6, the driving member includes a push rod 15 and a slider 11. The push rod 15 movably penetrates through the side wall of the water inlet part 1. One end of the sliding block 11 is connected with one end of the push rod 15 positioned in the water inlet part 1 through the hinge piece 12, and the other end is slidably arranged in a chute preset on the surface of the partition board 10. When pushing the push rod 15, the sliding block 11 slides in the sliding groove to drive the partition board 10 to rotate.
The specific type of hinge 12 is not limited and can be adjusted in rotation between the push rod 15 and the slider 11. Such as a hinge. In the invention, in order to further improve the degree of freedom between the push rod 15 and the sliding block 11, namely, on the premise that the sliding block 11 is not moved, the push rod 15 freely rotates along the central axis of the push rod, and the hinge 12 adopts a spherical hinge.
In one embodiment of the present invention, in order to reduce the overflow degree at the interface between the push rod 15 and the water inlet portion 1, sealing gaskets are disposed on both sides of the notch on the sidewall of the water inlet portion 1 for the push rod 15 to move. Two sealing balls 14 are arranged on the push rod 15 at intervals. When the water inlet part 1 is in a water flow blocking state, the sealing ball 14 positioned outside the water inlet part 1 seals the notch. When the water inlet part 1 is in a water flow state, the sealing ball 14 positioned in the water inlet part 1 seals the gap.
On the basis of this embodiment, in order to improve the safety of the whole inlet valve, as shown in fig. 7-9, a cavity 101 is provided in the inlet portion 1. The outer side wall of the water inlet part 1 is provided with a notch for the passage of the sealing ball 14. The side wall of the push rod 15 is provided with a lower limit rod. Wherein, in the pushing process of the push rod 15 into the water inlet part 1, when the sealing ball 14 enters the cavity 101 from the notch and is attached to the notch, the lower limit rod is rotated, so that the lower limit rod is clamped in the cavity 101, and the water inlet part 1 enters a water flow blocking state.
The bottom of the cover plate 3 is provided with a limit clamping groove. Specifically, the limiting clamping groove is formed by a narrow diameter section and a wide diameter section from the bottom of the cover plate 3 upwards. An upper limit rod 16 is arranged on the top of the push rod 15. The width of the narrow diameter section is slightly greater than the width of the upper stop bar 16. The wide diameter section allows the push rod 15 to rotate at an angle internally. When the cover plate 3 is matched with the water outlet part 2, the opening of the limiting clamping groove is opposite to the upper limiting rod 16. In the process of pulling out the push rod 15 to the outside of the water inlet part 1, when the sealing ball 14 is attached to the notch, the upper limit rod 16 is rotated, so that the lower limit rod is clamped in the limit clamping groove, and the water inlet part 1 enters a water flow state.
It should be noted that, when the water inlet portion 1 is in the water flow state, the upper limit lever 16 is located at the wide diameter section of the limit slot, and under the action of the limit slot, the upper limit lever 16 cannot move up and down, so that the water flow state can be maintained; meanwhile, since the upper limit rod 16 is located in the limit clamping groove, when the cover plate 3 and the water outlet part 2 relatively rotate, the upper limit rod 16 interferes, so that the filtering part cannot be integrally detached in a water flow state, and the filtering part cannot be taken out without cutting off water flow, so that water flow cannot be filtered. The filter screen 7 can filter even if the detachable inner plate 4 is removed without cutting off the water flow.
When switching to the water flow blocking state, the push rod 15 is rotated first to enable the upper limit rod 16 to be taken out from the narrow-diameter section, the push rod 15 is pressed downwards until the upper limit rod 16 is separated from the limit clamping groove, the lower limit rod enters the cavity 101 from the notch, and the push rod 15 is rotated to enable the lower limit rod to be clamped in the cavity 101 and enter the water flow blocking state.
In both the water flow blocking state and the water flow circulating state, a sealing ball 14 is attached to the notch to prevent water flow from overflowing.
In order to prevent the upper limit rod 16 and the lower limit rod from rotating, an elastically telescopic clamping block 17 can be arranged on the upper surface of the upper limit rod 16 and the lower limit rod, and a ball is arranged at the top of the clamping block 17. And a semicircular groove is arranged at the corresponding position of the limiting clamping groove and the cavity 101, and when two water flow states are required to be maintained, the push rod 15 is rotated until the ball at the top of the clamping block 17 is positioned in the semicircular groove. When the state is required to be changed, the balls can be separated from the semicircular grooves by applying a certain external force.
The foregoing describes one embodiment of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
