  • Patent number: 11256265
    Abstract: Embodiments of the present application relate to the field of ground detection, and disclose a ground detection device, a robot and a ground detection method. The ground detection device includes a control circuit, a signal trigger circuit, a signal sampling circuit and an amplification circuit. Where, the signal sampling circuit is configured to acquire reflected light of the optical signal reflected by a detection area and ambient interference light, and to generate a second voltage signal according to the reflected light and the ambient interference light; the amplification circuit is configured to amplify the second voltage signal to acquire a third voltage signal; and the control circuit is configured to compare the third voltage signal with a preset voltage, and to determine whether there is a ground within the detection area according to a comparison result.

  • Publication number: 20200309709
    Abstract: A rotating seal-type liquid testing apparatus includes a lower cup component, an upper cup body, a top cover and a testing element. The lower cup component includes a lower cup body, a high liquid baffle, a low liquid baffle and a water-absorbing sealing plug. The low liquid baffle and the high liquid baffle divide a bottom of an inner cavity of the lower cup body into a reaction region and a cut-off region. An edge of a bottom surface of the inner cavity of the lower cup body is provided with a vent hole, and the vent hole is positioned in the cut-off region. The upper cup body is disposed in the lower cup body, a bottom surface of an inner cavity of the upper cup body is provided with a liquid outlet, and the liquid outlet is connected to the reaction region in the lower cup body.
