[0056] When in the first state, the first one-way valve 3 is in an open state and the second one-way valve 4 is in a closed state;

[0061] Furthermore, the device further includes:

[0062] A first hose 120 communicated with the first port 12;

[0069] A sand box 8, and the first hose 120 is in internal communication with the sand box 8.

[0071] Further, both ends of the second through port 13 are on the same horizontal line.

[0072] Further, both the first hose 120 and the second hose 130 are rubber hoses.

[0073] Further, both the first hose 120 and the second hose 130 are fixedly connected and communicated with the corresponding first through port 12 and the second through port 13 respectively through hose clamps.

[0074] Specifically, based on the technical solution of the embodiments of the present application, the sand cleaning and sand injection processes performed thereon are specifically described.

[0075] First, the sand cleaning process is as shown in the Figure 3 figures of the specification:

[0076] First, press the switching control member 5. The first one-way valve 3 is in a closed state, and the second one-way valve 4 is in an open state.

[0077] Secondly, turn on the air source member 6. A negative pressure area is formed at the first channel 10 to the first through port 12, so that the sand on one side of the first hose 120 can be sucked in and discharged from the second hose 130;

[0078] When the sand container 7 and the sand box 8 are assembled, the quartz sand in the sand box 8 will be sucked in from one side of the first hose 120 and discharged from the second hose 130 to the sand container 7.

[0079] During this process, the specific structural principle is as follows:

[0080] After the high-pressure air flow provided by the air source member 6 passes through the second one-way valve 4, due to the eddy current effect of the first channel 10, the air flow will choose to flow to the unobstructed second through port 13. The air flow flows at a high speed, so that a negative pressure area is formed at the first channel 10 to the first through port 12, providing an adsorption effect. The quartz sand in the sand box 8 will be sucked in from the first through port 12. After passing through the negative pressure area, the air flow will accelerate to let the quartz sand flow to the second through port 13.

[0081] Second, the process of injecting sand is as shown in the attached drawings of the specification Figure 4 as follows:

[0082] First, press the switching control component 5. The first one-way valve 3 is in the open state, and the second one-way valve 4 is in the closed state.

[0083] Second, turn on the air source component 6. A negative pressure area is formed at the first channel 10 to the second port 13, so that the sand on one side of the second hose 130 can be sucked in and discharged from the first hose 120.

[0084] When the sand container 7 and the sand box 8 are assembled, the quartz sand in the sand container 7 will be sucked in from one side of the second hose 130 and injected into the sand box 8 from the first hose 120.

[0085] During this process, the specific structural principle is as follows:

[0086] After the high-pressure air flow provided by the air source component 6 passes through the first one-way valve 3, due to the eddy current effect of the first channel 10, the air flow will choose to flow to the unobstructed first port 12. The air flow flows at a high speed, so a negative pressure area is formed at the first channel 10 to the second port 13, providing an adsorption effect. The quartz sand in the sand container 7 will be sucked in from the second port 13. After passing through the negative pressure area, the air flow will accelerate to let the quartz sand flow to the first port 12.
