Description

Cupping device air path structure capable of manually adjusting pressure Technical Field The utility model belongs to the field of physiotherapy robot equipment, and particularly relates to a cupping equipment air path structure capable of manually adjusting pressure. Background Cupping is a traditional Chinese medicine therapy which uses a cupping tool, utilizes methods of burning fire, exhausting air and the like to generate negative pressure so as to be adsorbed on a body surface to cause local blood stasis, and achieves the effects of clearing and activating the channels and collaterals, promoting qi and activating blood circulation, relieving swelling and pain, dispelling wind and dispelling cold and the like. Along with development of science and technology, the combination of cupping and cooperation robot-negative pressure physiotherapy robot is realized, and compared with traditional cupping, negative pressure physiotherapy robot produces vacuum through the air pump, makes the suction head generate heat through the mode of electrical heating, realizes fixed point cupping through six cooperation robots's accurate removal and walks the jar, is a more convenient, more efficient cup form. However, the existing negative pressure physiotherapy robot cupping can control the negative pressure by continuously starting and stopping the vacuum pump, when the vacuum pump does not reach a preset pressure value, the vacuum pump always works, otherwise, the vacuum pump stops, the repeated starting and stopping can reduce the failure rate of the vacuum pump and improve, and the negative pressure value of the system is always in the highest state.
