The arrangement of the rubber pad enables the nut to be matched with the limiting part better, and the joint pipe can be connected with the water tank better.

In the above water feed joint of a sprayer, the joint pipe is made of a plastic material. The joint pipe is integrally formed through injection molding, and the processing is convenient.

Compared with the prior art, the water supply joint of the sprayer provided by the utility model has the following advantages:

1. the joint pipe of the water supply joint is of an integrated structure, and no gap exists at the joint between the joint pipe and the side wall of the tank body, so that the problem of water leakage does not exist at the joint between the joint pipe and the water tank.

2. This send water swivel to cooperate through the spacing portion on nut and the joint pipe, can make send water swivel tighter to link firmly mutually with the water tank through swivel nut, fixed firm degree is high.
