1. An ultrasound device, comprising:
a body;
an ultrasonic head, configured to be connected to the body through a lead wire or wirelessly and configured to generate ultrasound; and
a fixing piece comprising a cover plate and a peripheral wall circumferentially and vertically connected with the cover plate; wherein the peripheral wall is sleeved on the ultrasonic head to form an accommodation space between the ultrasonic head and the cover plate; a first through hole is provided on the cover plate, and the first through hole communicates with the accommodation space; and
an ultrasonic coupling gel configured for ultrasound to pass through; wherein the ultrasonic coupling gel comprises a first connecting part and a protruding part; the first connecting part is accommodated in the accommodation space and directly attached to the ultrasonic head and the cover plate respectively and simultaneously; and the protruding part is arranged on the first connecting part and is exposed outside the fixing piece through the first through hole;
wherein, the ultrasonic head comprises a first clamping part, and the first clamping part comprises a plurality of first protruding structures, wherein the plurality of the first protruding structures are evenly distributed; a portion of the peripheral wall that is separate from a side of the cover plate comprises a second clamping part, and the second clamping part is around the peripheral wall of a circumferential protruding structure or one or more second protruding structures; an inner part of the peripheral wall comprises an annular groove that is coupled with the circumferential protruding structure or the one or more second protruding structures, the first clamping part protrudes into the annular groove of the second clamping part, and the peripheral wall is configured to be sleeved on the ultrasonic head;
wherein a circumferential direction of the circumferential protruding structure or the one or more second protruding structures comprises corners bending toward the inner part of the peripheral wall, and the corners guide and cooperate with the first clamping part in the plurality plurality of first protruding structures to accelerate assemblance of the fixing piece and the ultrasonic head;
wherein, the peripheral wall comprises a first plurality of magnetic attractors evenly distributed along a circumferential direction of the peripheral wall, the ultrasonic head comprises a second plurality of magnetic attractors evenly distributed along the circumferential direction of the ultrasonic head, and the first plurality of magnetic attractors and the second plurality of magnetic attractors cooperate to ensure a uniform force between the fixing piece and the ultrasonic head; and
wherein the first plurality of magnetic attractors are arranged on a surface of the peripheral wall other than a horizontal end surface of the peripheral wall, and the second plurality of magnetic attractors are arranged on a surface of the ultrasonic head other than a horizontal end surface of the ultrasonic head.
