[0014] Figure 3 is a schematic view of a motor, an impeller and an inlet cover arranged under the rear pump cover according to the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The present utility model relates to a barrel structure of a water pump, as Figure 1 — Figure 3 shown, including a barrel body 1, a rear pump cover 2 and a handle 3. The barrel body 1 is a barrel with open upper and lower ends. The rear pump cover 2 is arranged in the barrel body 1. A large platform 5 is arranged on the rear pump cover 2. The large platform 5 is matched with the inner wall of the upper opening of the barrel body 1, and a sealing structure is arranged between the large platform 5 and the inner wall of the upper opening of the barrel body 1. A water outlet interface 6 is arranged on the large platform. The handle 3 includes a cover seat 31 arranged on the upper opening of the barrel body 1. A handle 32 is arranged on the cover seat. A round hole 33 is also arranged on the cover seat. The water outlet interface 6 extends out of the round hole 33. In an actual product, a motor 11 is arranged under the rear pump cover 2, an impeller 12 is connected under the motor, and an inlet cover 13 is arranged at the lower opening of the barrel body 1. In this solution, the barrel body 1 adopts an open structure at both the upper and lower ends, and a large platform 5 replaces the traditional top surface of the barrel body, and a sealing structure is arranged between the large platform and the inner wall of the upper opening of the barrel body. At the same time, the handle 3 is composed of a cover seat 31 and a handle 32. The cover seat 31 is arranged at the upper opening of the barrel body 1 to cover the large platform 5. The water outlet interface 6 extends out of the cover seat 31. The structural improvement is reasonable.
