  • Patent number: 10647111
    Abstract: Provided is a liquid droplet forming device including: a liquid container capable of containing a liquid; a membranous member disposed at a bottom of the liquid container and including a discharging hole; a deforming unit capable of deforming the membranous member; and a driving unit configured to drive the deforming unit by outputting a discharging signal for deforming the membranous member to discharge the liquid or a suppressing signal for suppressing residual vibration of the membranous member, wherein the suppressing signal is a signal based on natural vibration period T0 of the membranous member, wherein an amplitude of the suppressing signal is lower than or equal to an amplitude of the discharging signal, and wherein interval time Ti from when outputting of the discharging signal is ended until when outputting of the suppressing signal is started satisfies a formula: Ti=(m?½)×T0, where m represents a positive integer.

  • Publication number: 20200023328
    Abstract: A droplet forming device is provided. The droplet forming device includes a liquid holder configured to hold a liquid, a film having a discharge hole, two or more vibration generators configured to vibrate the film, and a driver configured to apply a driving signal to the vibration generators. One or more of the vibration generators are disposed in each region on the film where a polarity of bending moment differs.

  • Patent number: 5820373
    Abstract: A periodontal pocket cleaning device is provided which has a very excellent effect for the prevention of periodontal diseases, which is least liable to cause injury to the periodontal pocket, which can be used at any place without limiting the place of its use, which is able to obtain a stabilized atomized jet without being influenced by the height position of the handy probe, and which is available at a low cost. The periodontal cleaning device includes a handy probe provided with an air-jet ejection mechanism, an air pump for producing compressed air, and an air-feeding tube for feeding the compressed air from the air pump to the handy probe. The handy probe is provided with a liquid storage tank for storing liquid agent such as water or liquid chemicals therein. The jet-out pressure of the compressed air to be ejected from the nozzle of the handy probe is set in a range of from 0.05 to 0.08 kg/cm.sup.2. The jet-out quanity of the compressed air is set in a range of from 2 to 30 l/min.
