Preferably, the cup further comprises a shell 4, the shell 4 is fixedly connected with the cup bottom 10, the sealing part 32 further comprises a connecting part 33, the lower part of the sealing part 32 is fixedly connected with the connecting part 33, the shell 4 is sleeved outside the connecting part 33, a first through hole 323 is formed inside the sealing part 32, a second through hole 333 is formed in the connecting part 33, an air inlet hole 322 is formed in the side surface of the sealing part 32, the first through hole 323 is communicated with the air inlet hole 322, and the first through hole 323 is communicated with the second through hole 333.

Preferably, a cavity is defined above the connecting portion 33, the shell 4, the sealing portion 32 and the cup bottom 10, the cavity is communicated with the vent hole 5, and the cavity is communicated with the air inlet hole 322.

Preferably, the connecting portion 33 is laterally formed with a second protrusion 331, and the second protrusion 331 is in interference fit with the housing 4. The second projection 331 serves to fix the position of the sealing member 3 and prevent leakage of paint.

Preferably, the connecting portion 33 is laterally formed with a third protrusion 332, the third protrusion 332 is inserted into the housing 4 and is adapted to the housing 4, and the third protrusion 332 is used for limiting the rotation of the sealing member 2.

Preferably, the sealing member 3 further includes a flange portion 34, the flange portion 34 is located at the bottom outer side of the connecting portion 33, the flange portion 34 is fixedly connected with the side surface of the connecting portion 33, and the flange portion 34 is used for limiting the upward movement of the sealing member 3.

Preferably, the lower part of the cup bottom 10 is fixedly connected with the supporting part 11, and the bottom surface of the supporting part 11 and the bottom surface of the flange part 34 are positioned on the same plane when the venthole 5 is closed.

The working principle is as follows:

when the paint is stored, the reservoir is upright as shown in fig. 1. At this time, the first protrusion 321 is inserted into the groove 51 to close the vent hole 5, and the paint does not leak downward out of the vent hole 5. If a small amount of paint flows out from the gap between the vent hole 5 and the sealing portion 32, it will flow into the cavity below, which serves as a buffer for storing the leaked paint, and the paint will not flow out of the housing 4.

During painting, the reservoir is inverted, i.e. rotated in fig. 1, with the liquid passage 21 below and the cup bottom 10 above, the liquid passage 21 being connected to the spray gun. The flange 34 is held by hand to pull the first protrusion 321 out of the groove 51, the vent hole 5 is opened, and the cup body 1 is vented to the outside. When the spray gun continuously sprays the paint in the cup body 1 outwards, the outside air can enter the cup body 1 through the vent hole 5 to balance the air pressure difference, and the cup body 1 is prevented from being broken due to the air pressure difference. As shown by the arrows in fig. 7 and 8, the air flows through the second through hole 333 and the first through hole 323 from the outside, then enters the cavity through the air inlet hole 322, and finally enters the inside of the cup body 1 from the cavity through the groove 51 of the vent 5. It should be noted that fig. 7 and 8 are illustrated in an upright state, and an upside-down state is assumed in actual painting.

If the paint is not used up, the reservoir is placed on a flat surface (e.g. a table top), flange portion 34 first contacts the flat surface, then cup 1 is forced downwardly by gravity or by hand, and housing 4 moves downwardly relative to flange portion 34 until support 11 contacts the flat surface, at which time vent 5 is closed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not necessarily depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
