the device is characterized in that a first sealing ring is arranged between the outer peripheral wall of the flange and the inner peripheral wall of the flow guide pipe.
In order to facilitate connection of the guide pipe and the upper spray arm, the guide pipe is connected with the upper spray arm through a water pipe, and the guide pipe is inserted into the first end of the water pipe. The length of the flow guide pipe can be made shorter, otherwise, the length of the flow guide pipe is too long, and the flow guide pipe is difficult to insert and assemble with the flange.
In order to ensure that the guide pipe and the flange are tightly matched so as to prevent water leakage, the first end of the guide pipe is sleeved on the flange, the port of the first end of the guide pipe extends outwards along the radial direction of the guide pipe to form an outer edge, and the outer edge is extruded between the end wall of the first end of the water pipe and the outer wall surface of the water supply pipeline. Because the water pipe is relatively fixed with the bowl basket, after the bowl basket is relatively fixed, the water pipe is relatively fixed, the guide pipe is extruded between the water pipe and the bowl basket which are fixedly arranged, displacement cannot occur easily, the guide pipe can be well matched with the flange, and the water leakage probability is reduced.
In order to facilitate the insertion and assembly of the water pipe and the guide pipe, preferably, the end of the first end of the water pipe has a tapered structure with gradually reduced diameter along the water flow direction. The conical structure plays a role in guiding, and when the second end of the guide pipe is in contact with the conical structure, the guide pipe can slide along the conical structure, so that the water pipe is aligned with the guide pipe, and quick and accurate insertion is realized; and the conical structure is also convenient for the honeycomb duct to be inserted into the water pipe.
In order to prevent the outer edge from excessively interfering with the water pipe to damage the component, a step surface is formed on the bottom wall surface of the water pipe, and the second end of the guide pipe is abutted against the step surface in the state that the guide pipe is inserted into the water pipe. Therefore, the depth of the guide pipe inserted into the water pipe is limited, the outer edge can be guaranteed to be propped against the water pipe, and the propping pressure between the outer edge and the water pipe is not too high.
In order to prevent water leakage between the guide pipe and the water pipe, a second sealing ring is arranged between the outer peripheral wall of the guide pipe and the inner peripheral wall of the water pipe. Thus, the first sealing ring and the second sealing ring are matched together to be equivalent to two circles of radial sealing, and the probability of water leakage is greatly reduced.
Preferably, a circle of caulking groove is formed in the peripheral wall of the flow guide pipe, the second sealing ring comprises an annular ring embedded in the caulking groove and a circle of convex ribs formed on the annular ring, and the convex ribs can elastically press against the inner peripheral wall of the water pipe. The structure of the second sealing ring ensures tightness, and when the water pipe is pushed and pulled, the contact area between the second sealing ring and the water pipe is small, so that the push and pull hand feeling is good.
In order to reduce the fluid loss, the flow guide pipe is sequentially divided into a large-diameter part and a small-diameter part along the direction from the first end to the second end, the inner diameter of the large-diameter part is larger than that of the small-diameter part, the large-diameter part is sleeved on the flange, and the inner wall surface of the small-diameter part is flush with the inner wall surface of the flange. Therefore, a step surface is not formed at the joint of the guide pipe and the flange, and the fluid loss is reduced.
The utility model solves the second technical problem by adopting the technical proposal that: the utility model provides an use above-mentioned cleaning machine who spouts arm connection structure which characterized in that: the cleaning device comprises an upper spray arm and a box body with a cleaning cavity, wherein the upper spray arm connecting structure is arranged in the cleaning cavity, and the upper spray arm is connected with the second end of a water pipe and is in fluid communication with the second end of the water pipe.
In the scheme, the bowl basket is arranged in the washing cavity, the water pipe is connected with the bowl basket, and the bowl basket is not only used for placing tableware, but also used for positioning the water pipe.
Compared with the prior art, the utility model has the advantages that: according to the utility model, the first sealing ring is arranged between the guide pipe and the flange, so that the probability of water leakage between the guide pipe and the flange is reduced, and the fluid loss is reduced.
