[0014] By adopting the above technical solution, a limiting protrusion and a limiting groove are set, and the limiting protrusion of the closing block passes through the limiting hole and is embedded in the limiting groove to limit the end cover part, thereby reducing the situation where the end cover part accidentally rotates to cause the connecting hole 1 to the connecting hole 2.

[0015] Optionally, an anti-slip groove is provided on the outer wall of the end cover portion, and the anti-slip groove extends in a direction away from the bottle body portion.

[0016] By adopting the above technical solution, an anti-skid groove is provided, so that the user can contact the anti-skid groove to rotate the end cover part, thereby facilitating the powder discharging operation.

[0017] Optionally, an elastic convex ring is provided on the inner wall of the end cover portion, and a fixed ring groove is provided on the outer wall of the bottle mouth portion, and the fixed ring groove is for the elastic convex ring to be embedded.

[0018] By adopting the above technical solution, an elastic convex ring is provided, and the elastic convex ring is embedded in the fixed ring groove, so as to facilitate the limiting of the end cover part and reduce the separation of the end cover part from the bottle mouth part. Secondly, when it needs to be opened, the end cover part needs to be pulled hard, which also reduces the situation where users open it by mistake.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. A closing cover and an end cover are provided. When powder discharging operation is required, the end cover is rotated to connect the connecting hole 1 with the connecting hole 2. At this time, the bottle body can be shaken to make the powder shake out from the connecting hole 1. In this way, powder discharging is convenient;

[0021] 2. A limiting protrusion and a limiting groove are provided, and the limiting protrusion of the closing block passes through the limiting hole and is embedded in the limiting groove to limit the end cover, thereby reducing the situation where the end cover is accidentally rotated to cause the connecting hole 1 to the connecting hole 2 to be connected;

A closing cover 5 is provided at the notch of the receiving groove 4, and the closing cover 5 covers the receiving groove 4. The closing cover 5 is provided with a second communication hole 7, which passes through the closing cover 5, and the passing direction of the second communication hole 7 is a vertical direction. The closing cover 5 is also provided with a limiting groove 8, and the limiting groove 8 is located at an end of the closing cover 5 away from the bottle body 1.

[0029] The end cover 3 is located at the end of the bottle mouth 2 away from the bottle body 1, and the end of the end cover 3 close to the bottle body 1 abuts against the closing cover 5, and the end cover 3 is rotatably connected to the bottle mouth 2. The end cover 3 is provided with a connecting hole 1 6, and the connecting hole 1 6 is used to connect with the connecting hole 2 7 and thus indirectly connect with the receiving groove 4. The end cover 3 is also provided with a limiting hole 18, which passes through the end cover 3, and the limiting hole 18 is used to connect with the limiting groove 8. The outer wall of the end cover 3 is provided with an anti-skid groove 9, and the anti-skid groove 9 extends in a direction away from the bottle body 1. The setting of the anti-skid groove 9 facilitates the user to abut against the anti-skid groove 9 and rotate the end cover 3.

[0030] The end cover 3 is provided with an extension ring 10, which is located at one end of the end cover 3 away from the bottle body 1. The end cover 3 is provided with a closing block 11, which is located at one end of the end cover 3 away from the bottle body 1, and the closing block 11 abuts against the inner wall of the extension ring 10. The closing block 11 is provided with a mounting groove 12, which is located at one end of the closing block 11 away from the end cover 3. The groove wall of the mounting groove 12 is provided with a mounting rod 13, and the mounting rod 13 is provided with a handle 14, which is rotatably connected to the mounting rod 13, and the rotation axis direction of the handle 14 is the axis direction of the mounting rod 13.
