<p>A manufacturing process and device for a massage therapy head, and particularly a cleaning liquid for cleaning elements of the massage therapy head and a flexible bonding adhesive for the massage therapy head. The manufacturing process for the massage therapy head comprises four steps: cleaning, bonding, low-temperature drying and high-temperature drying. The prepared cleaning liquid can effectively eliminate attachments on the elements, and improve the bonding force between the elements and the bonding adhesive. The prepared bonding adhesive has proper hardness, is not easy to become brittle, and can effectively prevent an ultrasound plate from falling down while ultrasonic waves can easily penetrate through the bonding adhesive, so that the bonding adhesive does not damage the ultrasound plate as ultrasonic waves are not blocked and do not generate heat, and therefore the service life of the massager is greatly prolonged. The joint of a piezoelectric ceramic plate (3) and a sound transparent layer (2) after bonding is sealed and maintained through inert gases, and even tiny places of the bonding position are not corroded by oxygen and are not gradually stripped. The massage therapy head has an amplitude as large as 5 mm, and can be as firm as new after being used for more than 5 years.</p> |
