Through the setting of the sealing gasket, the seal between the partition 13 and the pump body 2 can be tighter, so that the operation of the vertical vacuum pump can be more stable, and the top of the cylinder 11 is movably connected with two valves 12. When the sealing plate 10 rises, the gas inside the cylinder 11 will drive the two valves 12 to rise, so that the valve 12 on the left can close the air inlet 14, and the valve 12 on the right can open the exhaust port 15, so that the gas inside the cylinder 11 can be discharged, otherwise the external gas can be sucked into the pump body 2 through the air inlet 14, and the bottom of the cylinder 11 is provided with a heat dissipation mechanism that penetrates to the outside of the pump body 2.

[0025] See also Figure 4 In order to cool down the vertical vacuum pump, the heat dissipation mechanism in this embodiment includes a contact plate 16, a heat pipe 17, a heat dissipation pipe 18, an exhaust assembly 19 and two air outlets 20. The contact plate 16 is a copper alloy plate, and the heat pipe 17 and the heat dissipation pipe 18 are both copper alloy pipes. The copper alloy has good thermal conductivity and can quickly transfer heat energy, so that the heat generated on the cylinder 11 can be quickly transmitted. The contact plate 16 is fixed to the bottom of the cylinder 11, the heat pipe 17 is fixed to the bottom of the contact plate 16, and the heat pipe 17 runs through the outside of the pump body 2.

[0026] In this embodiment, the exhaust assembly 19 includes a protective chamber, a fan, a three-way joint and a delivery pipe. The protective chamber is fixed to the front of the pump body 2, the fan is fixed to the inside of the protective chamber, the three-way joint is fixed to the output end of the fan, and the two delivery pipes are respectively fixed to the left and right sides of the three-way joint, and the delivery pipes extend to the outside of the protective chamber.

[0028] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

The vacuum pump can operate normally. When the sealing plate 10 and the cylinder 11 are in operation, the sealing plate 10 will rub the inside of the cylinder 11, thereby increasing the temperature of the cylinder 11. The high temperature generated by the cylinder 11 can be adsorbed through the contact plate 16, and the high temperature is transported to the heat dissipation pipe 18 through the action of the heat conduction pipe 17. Then, through the operation of the exhaust assembly 19, the air outlet 20 can blow up the heat dissipation pipe 18, so as to dissipate the heat of the cylinder 11, thereby achieving the purpose of cooling the vertical vacuum pump and preventing cracks in the vertical vacuum pump.
