Title:
VIBRATIONAL FREQUENCY ADJUSTMENT DEVICE AND WATER FLOW TYPE ORAL CAVITY CLEANING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/021523
Kind Code:
A1
Abstract:
Provided are a vibrational frequency adjustment device which can easily adjust the vibrational frequency and amplitude of reciprocating linear motion using a mechanical simple configuration, and a water flow type oral cavity cleaning device which uses the vibrational frequency adjustment device to enable the drive device for a sonic wave electric toothbrush to be also used for the pump drive means for the oral cavity cleaning device.
A vibrational frequency adjustment device comprises, as a vibrational frequency adjustment means (22): a first conversion means (40) which is provided with an input-side rotating member (41), an output-side rotating member (42), and a one-way clutch (44) for transmitting only the rotational motion in one direction of the input-side rotating member (41) to the output-side rotating member (42) and which, by causing the input-side rotating member (41) to pivot in a reciprocating manner by a set angle by means of the reciprocating linear motion of an output shaft (10), transmits only the forward motion or the reverse motion of the input-side rotating member (41) to the output-side rotating member (42) through the one-way clutch (44) to thereby rotate the output-side rotating member (42) by a given angle; and a second conversion means (50) which converts the rotational motion of the output-side rotating member (42) into the reciprocating linear motion of a second shaft member (43).
