The invention discloses a vacuum pump. The vacuum pump comprises a pump body, an air inducing chamber, a gear chamber, a motor chamber and an air outlet channel are formed in the pump body, the air inducing chamber, the motor chamber and the air outlet channel communicate with one another, an ash blocking net is welded to the bottom of the air inducing chamber, and a motor is fixedly arranged in the motor chamber; and an output shaft of the motor penetrates through the inner wall between the motor chamber and the gear chamber to be welded with a main shaft, a first gear is welded to the top end of the main shaft and engaged with a second gear, a fan shaft is welded to the rotating center of the second gear, and the fan shaft penetrates through the inner wall between the gear chamber and the air inducing chamber and extends into the gear chamber. According to the vacuum pump, the motor can be cooled in the working process of the vacuum pump, the situation that the service life of the motor is shortened due to the fact that the motor generates large heat in the working process is avoided, dust can be prevented from entering, and the situation that aging of the internal structure of the vacuum pump is accelerated due to dust entering, and the service life of the vacuum pump is shortened is avoided.
Description
technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a vacuum pump. Background technique [0002] A vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. It can use mechanical, physical, chemical or physicochemical methods to pump up the pumped container to obtain a vacuum device or equipment. The working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. However, the existing vacuum pumps will generate a certain amount of heat due to the high-speed rotation of the motor during the pumping process, which will reduce the life of the motor, and in the process of pumping, due to the entry of dust, the inside of the vacuum pump will be The structure of the vacuum pump is polluted, the aging is accelerated, and the service life of the vacuum pump is shortened. Based on this, a vacuum pump is desi...
