Abstract
The utility model relates to an exhauster, which has good stability and rainproof upward outdoor exhaust port and is characterized in that: the upper sleeve is provided with a bearing pipe in the middle and is connected into a whole through a grid, and the bearing is tightly sleeved in the bearing pipe; the inner wall of the rotor pipe is tightly sleeved with a rotor, namely a magnetic ring, of the motor, a fan is arranged on the periphery of the rotor pipe, the pipe orifice is downward, a rotating shaft extends upwards from the center of the bottom of the rotor pipe, and the rotating shaft is tightly sleeved in a bearing; the lower sleeve is provided with a stator tube in the middle, the lower sleeve is connected into a whole through a connecting rib, the tube opening is upward, the lower end of the stator of the motor is tightly sleeved in the stator tube, and the electric wire penetrates out downwards; when the upper sleeve and the lower sleeve are tightly sleeved, the rotor is loosely sleeved on the periphery of the stator, and the lower end of the rotor pipe is loosely sleeved on the periphery of the stator pipe.
Description
Technical Field
The utility model relates to an exhaust machine.
Background
The air expellers on the market have two drawbacks: firstly, because the bearing is arranged in the stator, the rotating shaft is small, the rotating shaft is not firmly combined with the fan, the fan can fall off, and the stability is poor when the fan is driven to operate; and secondly, the function of preventing rain and blocking animals from entering the exhaust machine is avoided, the exhaust port can not be upwards installed in the open air, and the exhaust port can only be transversely installed after being butted with a bent pipe. At present, there is no patent to solve this problem.
Disclosure of Invention
Therefore, the utility model provides an exhaust machine, which is characterized in that: the upper sleeve is provided with a bearing pipe in the middle and is connected into a whole through a grid, and the bearing is tightly sleeved in the bearing pipe; the inner wall of the rotor pipe is tightly sleeved with a rotor, namely a magnetic ring, of the motor, a fan is arranged on the periphery of the rotor pipe, the pipe orifice is downward, a rotating shaft extends upwards from the center of the bottom of the rotor pipe, and the rotating shaft is tightly sleeved in a bearing; the lower sleeve is provided with a stator tube in the middle, the lower sleeve is connected into a whole through a connecting rib, the tube opening is upward, the lower end of the stator of the motor is tightly sleeved in the stator tube, and the electric wire penetrates out downwards; when the upper sleeve and the lower sleeve are tightly sleeved, the rotor is loosely sleeved on the periphery of the stator, and the lower end of the rotor pipe is loosely sleeved on the periphery of the stator pipe.

Detailed Description
As shown in the figures, the present invention is characterized in that: the upper sleeve 1 is provided with a bearing tube 1.1 in the center, and is connected into a whole through a grid 1.2, and a bearing 4 is tightly sleeved in the bearing tube 1.1. The inner wall of the rotor pipe 3 is tightly sleeved with a rotor 5 of a motor, namely a magnetic ring, the periphery of the rotor pipe is provided with a fan 3.2, the pipe opening is downward, the bottom of the rotor pipe is upwards extended in the middle to form a rotating shaft 3.1, and the rotating shaft 3.1 is tightly sleeved in a bearing 4. The diameter of the upper section part of the lower sleeve 2 is larger, the diameter of the lower section part is smaller to form a step, the upper section part is centered with a stator tube 2.1, the upper section part is connected into a whole through a connecting rib 2.2, the tube opening faces upwards, the lower end of a stator 6 of the motor is tightly sleeved in the stator tube 2.1, and an electric wire 7 penetrates out of the tube from the step downwards. When the upper sleeve 1 and the upper section part of the lower sleeve 2 are tightly sleeved, the rotor 5 is loosely sleeved on the periphery of the stator 6, and the lower end of the rotor pipe 3 is loosely sleeved on the periphery of the stator pipe 2.1. When the stator 6 is electrified, the rotor 5 rotates around the stator 6, and simultaneously drives the fan 3.2 to rotate, so that the purpose of exhausting air upwards is achieved. The diameter of the rotating shaft 3.1 is larger, so that the rotating shaft is firmly combined with the rotor pipe 3 and cannot fall off, and the fan 3.2 runs stably. Because stator pipe 2.1 loose cover is in rotor pipe 3, and electric wire 7 is worn out down, the rainwater can not drench stator 6. Because the grid 1.2 is arranged in the upper sleeve 1 for blocking, animals such as bats and the like can not enter the exhaust machine.
