[0002] The ultrasonic head structure involved in the utility model is used in a type of ultrasonic beauty device that can implement non-invasive beauty technology, which is commonly known as an ultrasonic gun. An energy converter is provided inside the ultrasonic gun, which can emit ultrasonic waves forward. The ultrasonic waves are transmitted through a liquid sound-conducting medium and then irradiate human subcutaneous tissue to emit ultrasonic waves. The ultrasonic gun needs to be provided with an opening for ultrasonic waves to be transmitted, and usually a liquid sound-conducting medium needs to be added inside the ultrasonic gun to facilitate ultrasonic wave propagation. Therefore, the ultrasonic gun needs to be provided with a waterproof membrane to prevent the liquid sound-conducting medium from leaking out, and at the same time, to prevent external liquid from entering the ultrasonic gun and affecting the normal operation of the ultrasonic gun.

[0003] Currently, the waterproof membrane of the ultrasonic cannon is directly attached to the outer shell of the ultrasonic head to cover the opening. If a hard object hits the waterproof membrane, it is easy to scratch the waterproof membrane, affecting the normal use of the ultrasonic cannon. Utility Model Content
