Description

Technical Field

[0001] The utility model belongs to the technical field of dental diagnosis and treatment, and particularly relates to a connection structure of a sandblasting pot and sandblasting equipment. Background Art

[0002] Sandblasting is a commonly used technique in both oral prevention and treatment. Sandblasting equipment is essential for this process. Typically, sandblasting equipment uses an external air source to power the device. Compressed air flows through a canister of dental blasting powder, carrying some of the powder through the equipment's pipes and ultimately out through the handle.

[0003] The sand powder tank is a component of the sandblasting equipment that temporarily stores and supplies sandblasting powder. Before the treatment begins, the sandblasting powder needs to be poured into the sand powder tank. After the treatment, the remaining sand powder in the sand powder tank needs to be poured out, and the sand powder attached to the inner wall or channel needs to be cleaned. If it is not cleaned in time, the sand powder will absorb moisture from the air and become damp and lumpy, which will affect subsequent use. For example, the fluidity of the sand powder will be reduced, the amount of sand output will be reduced, and the cleaning effect will be poor; it may also be caused by the sand powder adhering to the channel and causing blockage. Therefore, the sand powder tank needs to be frequently plugged into and removed from the main unit, and the connection between the sand powder tank and the main unit has high requirements. It must ensure good sealing after connection and be convenient for users to plug and unplug. The existing sand powder tank is prone to falling off during operation after being connected to the main unit, and the sealing effect is poor.

[0004] Based on this, it is necessary to improve the defects in the existing technology to overcome the shortcomings in practical applications. Utility Model Content
