Description

Spraying structure and dish washer Technical Field The application relates to the technical field of dish washers, and particularly provides a spraying structure and a dish washer. Background The back water conduit of the dish-washing machine is usually a water inlet pipeline positioned at the rear part of the dish-washing machine, the water inlet end of the water conduit is communicated with an external water source, the main function is to introduce the external water source into the dish-washing machine, the middle water conduit of the dish-washing machine is positioned at the middle part of the dish-washing machine and is communicated with the water outlet end of the back water conduit, the water conduit plays roles of transferring and distributing water flow in the dish-washing machine, and the water flow is guided to the water conduit at the spray arm. However, there are problems with the current sealed connection between the back and middle penstocks. The existing sealing structure mostly adopts a split type structure, and because the sealing element is composed of a plurality of split parts, each part needs to be accurately positioned and installed during installation, so that the time and difficulty of installation are increased, and higher requirements are put forward for the technical level of installation personnel. In addition, the split seal is prone to loosening or shifting during long term use due to the connection between the various components, resulting in a greatly compromised sealing effect. Once the sealing is not tight, the pressure of water flow entering the spray arm is possibly insufficient, the spraying force of the water is weakened, and the cleaning impact force is influenced. In view of this, there is a need in the art for a new solution to the above-mentioned problems. Disclosure of utility model The application aims to solve the technical problems, namely, the problems that the sealing of a back water diversion pipe and a middle water diversion pipe is not tight, so that water flow is leaked and the water pressure and the spraying effect are affected in the existing dish washing machine. In a first aspect, the present application provides a spray structure comprising: a first tube body; a second pipe body connected to the first pipe body; The sealing assembly is arranged at the joint of the first pipe body and the second pipe body and comprises a sealing frame and a sealing ring arranged on the sealing frame, the sealing frame and the sealing ring are integrally formed, and the first pipe body passes through the sealing ring to be communicated with the second pipe body. Under the condition of adopting the technical scheme, the spraying structure seals between the pipe bodies due to the adoption of the integrally formed sealing assembly, compared with the traditional assembly mode, the problem of gaps and looseness possibly occurring in the traditional assembly mode can be avoided, the sealing effect between the pipe bodies is improved, and the leakage phenomenon can be avoided in the water flow conveying process. Optionally, the sealing ring comprises a clamping part, and the peripheral wall of the first pipe body abuts against the clamping part. Under the condition of adopting the technical scheme, the clamping force can be generated on the first pipe by the clamping part when the first pipe body passes through, so that the connection between the first pipe body and the sealing ring is tighter and firmer. Optionally, the inner diameter of the clamping part gradually decreases towards the side of the second pipe body. Under the condition of adopting the technical scheme, the inner diameter of the clamping part is continuously tapered towards the second pipe body side along the first pipe body inserting direction, and a guiding conical surface is formed. The guiding conical surface can provide guiding and enable the insertion process to be smoother when the first pipe body is inserted into the sealing ring, and simultaneously, radial holding force can be provided, so that the first pipe body is more tightly and stably connected with the sealing ring. Optionally, be provided with a plurality of through-holes on the sealing frame, every the through-hole corresponds to set up one the sealing washer, seal assembly still includes: the sealing piece is connected between the second pipe body and the sealing frame, so that the joint of the sealing frame and the second pipe body is sealed, the sealing piece comprises a water baffle, the water baffle is used for sealing the through hole in a natural state, and the water baffle can rotate relative to the sealing piece under the action of external force so as to open the through hole. Under the condition of adopting the technical scheme, through setting up a plurality of through-holes at seal assembly to close or open through-hole through the breakwater, and then can realize the regulation of second body height. Optionally, the sealing ri
