[0002] As a vertical transportation tool, elevators play an important role in today's society. With the improvement of people's living standards and the pursuit of quality of life by high-income people, the market for home elevators has gradually grown. However, the existing home elevators have low floors. When the elevator is running, the traction motor generates a lot of noise, which will be transmitted into the room along the shaft, easily affecting the residents' rest, so the traction motor needs to be damped and noise reduced.

[0003] The patent with the publication number CN212953750U discloses a shock-absorbing and noise-reducing device for a household elevator, including a noise-reducing shell, a ventilation shell fixedly connected to the top of the noise-reducing shell, a shock-absorbing device fixedly connected to the bottom of the inner cavity of the noise-reducing shell, a mounting seat connected to the top of the shock-absorbing device, a traction machine installed on the top of the mounting seat, a limit plate fixedly connected to the mounting seat, the limit plate sleeved on the outside of the traction machine, and a traction wheel connected to one end of the traction machine. The present invention is provided with a noise-reducing shell, and the traction machine is installed in the noise-reducing shell when the traction machine is used. By providing a shock-absorbing device, the shaking of the mounting seat drives the spring to compress when the traction machine is running, and the shock-absorbing rod drives the slider to slide in the slide groove, which plays a good shock-absorbing role. By providing sound-absorbing cotton and rubber pads, the noise can be further absorbed, the sound propagation can be reduced, and the noise generated by the operation of the traction machine can be prevented from affecting the rest of the residents, which is convenient for the use of the elevator. The ventilation shell is provided with heat dissipation holes. However, some noise will still be emitted from the heat dissipation holes. Summary of the invention
