Description

Damping mechanism of drainage device

The invention relates to a drainage device, and in particular to a damping mechanism for a drainage device.

In the existing drainage device, since the motor and the drainage blade are provided inside, the vibration of the motor itself and the vibration generated by the disturbance of the water flow when the drainage blade rotates cause vibration of the overall drainage device, thereby generating noise. For some drainage devices, such as split-type air-conditioning indoor unit drainers, the indoor unit of the separate air-conditioning system is itself an extremely low-noise electrical device, so the drain itself must be designed to be extremely low-noise equipment. As a result, a good shock absorption design is a necessary technology for today's drainage devices.

The applicant of this case has previously applied for the "Adhesive Shelf" patent of China's Announcement No. M465719. The case is mainly to use an elastic frame to be fixed on a drainage device, and then a driving unit (including a motor) is disposed on the elastic frame. On the board, the vibration generated by the driving unit during operation can be absorbed by the elastic frame, thereby achieving the effect of damping.

The applicant of the case believes that the aforementioned case is a kind of structure for shock absorption. When the shape of the motor is larger and the weight of the drive unit is heavier, there should be other designs that can provide shock absorption.
