Embodiment 1
[0020] Such as figure 1 and figure 2 As shown, a sucker structure for an intermediate frequency electrotherapy instrument includes a hemispherical sucker body 3, and a hygroscopic body 1 is also arranged in the sucker body 3, and the hygroscopic body 1 is connected with the sucker body 3 through a spring 5, and absorbs moisture The body 1 and the suction cup body 3 form a detachable connection relationship.
[0021] In this embodiment, the hygroscopic body 1 arranged in the suction cup body 3 is convenient to be used as the liquid medicine carrier of the intermediate frequency electrotherapy instrument in the treatment or rehabilitation process, and the structure of using the hygroscopic body 1 as the liquid medicine carrier is convenient when the liquid medicine needs to be applied externally at the position where the suction cup is worn. , the liquid medicine is not in contact with the suction cup body 3 and the contact part of the human body, which is convenient to mainta...
Embodiment 2
[0023] The present embodiment is further limited on the basis of embodiment 1, as figure 1 and figure 2 As shown, as a structural form of the hygroscopic body 1 for easy disassembly and installation, a spring seat 4 is also provided in the suction cup body 3, one end of the spring 5 is fixedly connected to the spring seat 4, and the other end of the spring 5 is fixedly connected There is a screw seat 2, and the hygroscopic body 1 is connected with the screw seat 2 through screws 6. Preferably, after the moisture absorbing body 1 and the screw seat 2 are fixed, the screw 6 is concave relative to the outer surface of the moisture absorbing body 1 .
[0024] As a structural form that facilitates the wearing stability of the suction cup body 3 , the axial direction of the spring 5 is located in the depth direction of the suction cup body 3 .
[0025] As a structural form that facilitates the wearing comfort of the suction cup body 3, there are more than one spring 5, and the sp...
