Water-proof mechanism of dust collector generator chamber

Abstract

The invention discloses a water-proof mechanism of cleaner motor, which contains hollow motor lid, wherein the irradiating inlet and outlet are opened on the motor lid; the first water blocking lid is set on the exterior of irradiating inlet and the second water blocking lid is set on the exterior of irradiating outlet; the inlet and outlet channels are set on the water-proof mechanism; the irradiating inlet connects external space of first blocking lid through inlet channel; the irradiating outlet connects external space of second water blocking lid through outlet channel, which contains at least one baffle in the outlet channel along flow direction.

Description

technical field [0001] The invention relates to a waterproof mechanism for a motor room of a vacuum cleaner, which is used for preventing water from entering the motor room and is mainly applied to a portable vacuum cleaner. Background technique [0002] In the prior art, there is a motor cover outside the motor room of the vacuum cleaner, and there are many grid holes on the motor cover, so that the motor room communicates with the outside air, which is convenient for cooling the motor in the motor room. A shield is also provided to protect the motor against water. However, this mechanism can only prevent water from intruding into the motor at a specific angle, but cannot produce a comprehensive waterproof effect on the motor within a 360-degree range. Therefore, in practical applications, water will still enter the motor, especially for the input voltage at 45 For high-voltage motors above volts, the safety of this mechanism is low. At the same...

Problems solved by technology

However, this mechanism can only prevent water from intruding into the motor at a specific angle, but cannot produce a comprehensive waterproof effect on the motor within a 360-degree range. Therefore, in practical applications, water will still enter the motor, especially for the input voltage at 45 For high-voltage motors above volts, the safety of this mechanism is low. At the same time, due to the blocking effect of the shield, the airflow in the motor room is inconvenient, resulting in low heat dissipation efficiency of the motor and easy damage to the motor.
