  • Patent number: 8074378
    Abstract: A shock-absorbing method and device of an insole of a resilient shoe is provided. At least one transverse partition is set in a gas or liquid chamber of the insole. The gas or liquid chamber of the insole is partitioned into a fore cavity and a rear cavity by the partition. The fore cavity and the rear cavity are communicated reciprocally through the region external of the ends of the partition. Preferably, a fish-bone shaped partition is set longitudinally in the gas or liquid chamber. A column is set at the end of each of fish-bone branches of said fish-bone shaped partition and is positioned corresponding to a relevant acupoint of a human foot bottom. The gas or liquid chamber is filled with soft or resilient materials. The insole according to the invention could be shock absorbing and resilient.

  • Patent number: 7625150
    Abstract: A toothbrush has a toothbrush head, a toothbrush bar and a toothpaste container. The toothpaste container is a gas-filled container, and a gas nipple is provided at the bottom of the toothpaste container. A pipe channel is provided in the toothbrush bar, the toothpaste container is communicated with the toothbrush head through the pipe channel via a valve. The toothbrush bar is hinged to the toothpaste container by a spherical hinged joint formed by the end of the toothbrush bar. The spherical hinged joint controls the valve to discharge toothpaste in the toothpaste container into the pipe channel and the toothbrush head. The invention is convenient especially for children, the elder, the blind and the disabled.
