Description

Technical Field

[0001] The utility model relates to the technical field of dental mobile phone maintenance, in particular to an automatic oiling machine. Background Art

[0002] Dental handpieces are the most common medical devices in the dental industry and require regular maintenance and upkeep to ensure stable performance. Maintenance methods include manual maintenance and oiler maintenance. Oiler maintenance involves connecting the dental handpiece to a matching oiling adapter or connector and inserting it into the oiler for oiling. Currently, oilers supply oil, and one type of oiler works by using an external air source to fill an oil reservoir with compressed air. This compressed air then forces the lubricating oil out of the reservoir. The oil then flows through the oil circuit to a connecting piece with a mixing chamber, where it mixes with the air in the air circuit, forming an oil mist that is then injected into the dental handpiece. Its disadvantage is that when the oil tank is filled with compressed air, its internal pressure is relatively high. Long-term use may cause the risk of oil tank leakage or even separation of the connecting parts. In addition, the oil output controlled by air pressure is unstable, which can easily cause over-oiling or under-oiling, leading to maintenance failure. The working principle of another oiling machine is to pump out the lubricating oil in the oil tank through a peristaltic pump. The lubricating oil passes through the oil circuit to the connecting part with a mixing chamber and mixes with the air in the air circuit to form oil mist, which is then injected into the dental handpiece. Compared with air pressure, this structure is relatively safer.

[0003] However, the peristaltic pumps on the market basically use ordinary peristaltic pumps, which work on the principle of conveying fluid by alternately squeezing and releasing the elastic hose through a roller. At the moment of release, a liquid suction will occur, resulting in a sudden decrease in the discharged liquid, causing the peristaltic pump to produce continuous pulses, resulting in affected lubrication effects; when the peristaltic pump is working, if the oil storage tank is in a sealed state, negative pressure will inevitably be generated inside it, making it difficult to discharge oil. The oil storage tanks on the market all adopt the method of not locking the oil storage tank cover for a long time to avoid negative pressure, but this method will actually cause the lubricating oil in the oil storage tank to be exposed to the air for a long time, causing the lubricating oil to absorb moisture and deteriorate; when the oiling machine is working, the connection between its door cover and the main body is a simple mechanical connection, without corresponding circuit control. When the operator opens the door cover in advance when the equipment has not completed oiling, the equipment is still oiling, causing a large amount of oil mist to diffuse into the air, causing air pollution, and the rotor of the dental handpiece connected to the equipment is still rotating at high speed, which may cause harm to people.

[0006] Compared with the prior art, the beneficial effects of the present invention are: through the mutual cooperation of various connecting structures, the pulse phenomenon is effectively reduced when the multi-head pump is working, the lubricating oil is continuously and stably output in a quantitative manner, ensuring the consistency and effectiveness of lubrication; when the multi-head pump is not working, the solenoid valve disconnects the air path between the vent joint and the oil storage tank, isolating the oil storage tank from the outside air, preventing the lubricating oil from being exposed to the air and absorbing moisture and deteriorating; the safety door cover containing a magnetic control switch, after the door cover is opened, the oiler automatically stops supplying oil to the dental handpiece.
