Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a novel automatic oil injection and maintenance machine. Background Art

[0002] Dental handpieces are the most common medical devices in the dental industry and must be regularly maintained to ensure their stable performance. There are two types of maintenance methods: manual maintenance and machine maintenance. The specific method of manual maintenance is to connect the pressure tank filled with lubricating oil to a matching oil filling adapter or connector to inject lubricating oil into the dental handpiece. However, manual maintenance is prone to problems such as unstable fixation of the oil filling connector and the oil filling part of the dental handpiece, and the diffusion of oil mist from the head of the dental handpiece polluting the environment. The specific method of machine maintenance is to connect the dental handpiece to a matching oil filling adapter or connector and then insert it into an automatic oil filling and maintenance machine for oiling.

[0003] When the automatic oil filling and maintenance machine on the domestic market is filling oil, there is no effective cleaning device for the oil stains remaining in the machine cavity, and it can only be cleaned manually by the user. At the same time, the automatic oil filling and maintenance machine does not have a device for directly filling oil for the chuck or three-petal spring of the dental handpiece, and can only fill oil through the air inlet hole of the dental handpiece. This oil filling method enters the dental handpiece pipeline through the air inlet hole, and finally reaches the bearing, dental handpiece head and other components, and cannot effectively lubricate the chuck / three-petal spring, resulting in a large amount of lubricating oil wasted. In addition, the automatic oil filling and maintenance machine on the market does not have an effective dental handpiece conversion connector. Its connection method is to plug the dental handpiece into the oil filling machine and then fix the connection with a nut. This connection method makes it difficult to connect the handpiece to the oil filling machine and is not easy to operate. Utility Model Content

[0004] The purpose of the utility model is to provide a novel automatic oil injection curing machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of automatic oiling and maintenance machine, comprising a shell, an oil tank is fixedly connected to the inside of the back side of the shell, a groove body is opened on the front outer wall of the shell, a hole is opened on the middle side wall of the back side of the groove body, and a negative pressure suction joint is fixedly connected to the inside of the hole, a chuck oiling head, a high-speed mobile phone oiling head and a low-speed mobile phone oiling head are fixedly connected to the inner wall of the upper end of the groove body in sequence, a conversion joint is plugged into the high-speed mobile phone oiling head, and an oil collecting tank is fixedly connected to the lower end of the shell, and the oil collecting tank is communicated with the negative pressure suction joint.

[0006] Preferably, the upper end of the oil tank extends to the outer side of the upper end of the shell.

[0007] Preferably, an oil level identification plate is connected to a side wall on the front side of the shell, and the oil level identification plate is made of a transparent material.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: after the negative pressure suction device is added to the utility model, most of the oil mist will be sucked into the collection tank, and the inside of the machine cavity can maintain a relatively clean working environment. After the chuck / three-petal spring oiling device is added, the oiling machine can directly oil the chuck / three-petal spring, saving the oiling amount and improving the oiling efficiency. The utility model designs a new type of dental handpiece conversion connector, and the user can first hold the dental handpiece and plug it into the conversion connector and tighten it, and then plug the whole thing into the oiling machine for use.
