[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. Vacuum pumps are divided into two types: gas capture pumps and gas transmission pumps. They are widely used in metallurgy, chemical industry, food, electronic coating and other industries.

[0003] The current vacuum pump is generally composed of a motor, a pump body, an air inlet, an exhaust hole, an exhaust chamber, a connecting rod, a sealing disk and multiple valve bodies. When working, the motor drives the connecting rod to move longitudinally, thereby driving the sealing disk to move back and forth inside the exhaust chamber. At the same time, external air is counted into the exhaust chamber through the air inlet, and the gas inside the exhaust chamber is opened through a valve body on one side and discharged through the exhaust hole. However, when the existing oil vertical vacuum pump is working, dust in the air will enter the inner cavity of the oil vertical vacuum pump through the air inlet. When there is too much dust in the inner cavity, it is very easy to cause channel blockage. Therefore, the inventor proposes an oil-free vertical vacuum pump which is easy to clean the inner cavity to solve the above problem. Utility Model Content
