[0004] The following deficiencies exist in the use process of this electric sprayer: The battery cover of this electric sprayer is only buckled to the power supply box by an elastic clamping part. When the electric sprayer is carried on the back for use, the battery in the power supply box of the electric sprayer will collide with the battery cover, and the acting force of the collision of the battery is opposite to the buckling direction of the battery cover and the power supply box, resulting in a tendency that the battery cover is disconnected from the power supply box and the battery cover is turned downwards around the hinge axis under the collision of the battery, causing the battery cover not to be tightly covered, or even in a directly open state. Summary of the Invention

[0005] The purpose of the utility model is to propose a battery fixing structure of a sprayer in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the reliability of the battery fixing of the sprayer.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] A battery fixing structure of a sprayer, the sprayer includes a barrel body. This battery fixing structure includes a battery accommodation cavity provided on the barrel body and a cover plate for covering or opening the battery accommodation cavity. The characteristic is that a snap hook is provided on the barrel body. One end of the cover plate away from the snap hook is hinged to the barrel body. The other end of the cover plate has a positioning part. A buckle handle is hinged to the positioning part. A snap ring is hinged in the middle of the buckle handle. The snap ring is sleeved on the hook part of the snap hook and locks the snap hook on the positioning part, and the snap ring can be disengaged from the snap hook by pulling the buckle handle.

[0008] The battery fixing structure of this sprayer is provided with a snap hook on the barrel body, and a buckle handle is hinged on the positioning part of the cover plate. A snap ring is hinged in the middle of the buckle handle, which is sleeved on the hook part of the snap hook and locks the snap hook on the positioning part. When the battery in the battery accommodation cavity collides with the cover plate, the cover plate drives the buckle handle and the snap ring to rotate synchronously around the hinge joint between the cover plate and the barrel body. However, since the snap ring is still sleeved on the hook part of the snap hook, and the snap hook is arranged on the barrel body and does not move with the cover plate, the hook part of the snap hook can tightly hook the snap ring and prevent the further rotation of the snap ring, so that the cover plate can only be opened by the user by pulling the buckle handle to make the snap ring move away from the positioning part with the buckle handle and disengage from the snap hook, avoiding the situation that the cover plate is accidentally opened due to the battery colliding with the cover plate, thereby improving the reliability of the battery fixing of the sprayer.

[0009] In the battery fixing structure of the above-mentioned sprayer, the cover plate is arranged on the side part of the barrel body, the positioning part is arranged adjacent to the snap hook, the hook part of the snap hook is bent away from the positioning part, and limiting blocks are respectively arranged on the upper and lower sides of the positioning part.
