Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ultrasonic therapy, especially relates to an ultrasonic therapy head and ultrasonic therapeutic instrument. BACKGROUND

[0002] The ultrasonic therapeutic instrument mainly emits ultrasonic energy through the transducer arranged in the treatment head, the transducer is soaked in the water storage bin of the treatment head, and in order to ensure that the sound transmission medium in the water storage bin does not leak, the sound transmission membrane is often used for sealing on the end face of the water storage bin.

[0003] When the ultrasonic therapy head is used, the sound transmission membrane directly contacts the skin coated with ultrasonic coupling agent, and the treatment head often needs to be slid on the skin, if the sound transmission membrane is convex relative to the plane of the head part of the front cover of the treatment head, the skin is easily scratched during the treatment, therefore, when the water storage bin and the front cover of the treatment head are assembled, the sound transmission membrane needs to be avoided from being convex, but at the same time, the sound transmission membrane cannot be too concave, and if the sound transmission membrane is too concave, the ultrasonic coupling agent cannot fill the groove, and thus the energy output is abnormal or the energy depth is insufficient. Therefore, the installation of the front cover of the treatment head and the water storage bin must meet the precision requirements.

[0004] At present, in order to realize the positioning and installation of the front cover of the treatment head and the water storage bin, a plurality of installation columns are convexly arranged on the front cover of the treatment head, the installation columns are in contact with and abut against the water storage bin and are locked and fixed, and the relative position between the end face of the front cover of the treatment head and the sound transmission membrane is controlled by the size and height of the installation columns. However, in the injection molding production process of the front cover of the treatment head, the installation columns often need to be ejected by an ejection mechanism, and the ejection process can compress the height of the installation columns and thus cause size errors, and the ejection mechanism can also be worn in long-term use and thus cause the size errors to be enlarged.

[0029] The present application provides an ultrasonic treatment head 100.

[0030] Please refer to Figures 1 to 5 The embodiment of the present application includes a water storage bin 2 and a front cover 4, the front cover 4 is provided with a mounting column 41, the front cover 4 is covered on the water storage bin 2 and is fixedly connected with the water storage bin 2 through the mounting column 41, and one of the front cover 4 and the water storage bin 2 is provided with a positioning piece, and the other is provided with a positioning part matched with the positioning piece.

[0031] The ultrasonic treatment head 100 further includes a shell 1, and the water storage bin 2 is arranged in a cavity of the shell 1 and partially protrudes from the shell 1. The water storage bin 2 is filled with an acoustic medium, and the end surface of the water storage bin 2 is covered with a sound transmission film 3 to prevent the acoustic medium from leaking. The front cover 4 is provided with a mounting column 41, the front cover 4 is covered on the protruding part of the water storage bin 2 and is fixedly connected with the water storage bin 2 through the mounting column 41, and then the front cover 4 is connected with the shell 1.

[0032] When the water storage chamber 2 is assembled with the front cover 4, the sound permeable membrane 3 cannot protrude from the end surface of the front cover 4 or be too recessed, otherwise, the sound permeable membrane 3 will scratch the skin when the treatment head slides on the skin, and the recessed sound permeable membrane 3 will not be filled with the ultrasonic coupling agent, resulting in abnormal energy output or insufficient energy depth. The traditional ultrasonic treatment head usually controls the relative position between the end surface of the front cover 4 and the sound permeable membrane 3 by the size and height of the mounting column 41. However, in the demolding process of the front cover 4, the front cover 4 usually uses an ejection mechanism to apply a pushing force to the mounting column 41 to eject the front cover 4 from the mold, and the ejection process will compress the height of the mounting column 41 and cause size errors, and the ejection mechanism may also be worn in long-term use, which will cause the size error to expand.

[0033] Unlike the traditional ultrasonic treatment head 100, the ultrasonic treatment head 100 of the utility model is provided with a positioning member on one of the front cover 4 and the water storage chamber 2, and the other is provided with a positioning part matched with the positioning member, the positioning member and the positioning part are used to limit the relative position between the front cover 4 and the water storage chamber 2, and the mounting column 41 is used to realize the fixed connection between the front cover 4 and the water storage chamber 2. In the demolding process of the front cover 4, the ejection mechanism only abuts against the mounting column 41, and does not touch the positioning member or the positioning part, so the design height of the positioning member or the positioning part on the front cover 4 will not be affected by the demolding process. Since the relative position between the front cover 4 and the water storage chamber 2 is determined by the positioning member and the positioning part, the relative position between the front cover 4 and the water storage chamber 2 can meet the design requirements, and the relative position between the front cover 4 and the sound permeable membrane 3 can also meet the design requirements.

[0034] In actual application, the positioning member and the positioning part can be two buckling members buckling with each other, or abutting blocks abutting against each other. In some embodiments of the utility model, the front cover 4 is provided with a positioning column 42 to form a positioning member, and the water storage chamber 2 is provided with an abutting position to form a positioning part, and the positioning column 42 is buckled in the abutting position to realize the abutting and limiting of the front cover 4 and the water storage chamber 2. Of course, the positions of the positioning column 42 and the abutting position can be interchanged, that is, the positioning column 42 is protruded on the water storage chamber 2, and the abutting position is arranged on the front cover 4, which can also realize the abutting and limiting of the front cover 4 and the water storage chamber 2. In this embodiment, the front cover 4 and the water storage chamber 2 realize the abutting and limiting of the two by the positioning column 42 and the abutting position, which is simple in manufacturing process and convenient and fast in assembly process.

[0035] In an embodiment, the mounting column 41 and the positioning column 42 are both protruded from a side of the front cover 4 facing the water storage bin 2, the positioning column 42 is used to abut against a limiting position on the water storage bin 2, the mounting column 41 is used to be fixedly connected with the water storage bin 2, and the mounting column 41 is arranged in a spaced manner with the positioning column 42. In the demolding process of the front cover 4, the ejection mechanism does not need to abut against the positioning column 42, but only needs to abut against the mounting column 41 to push the front cover 4 to smoothly separate from the mold. When the front cover 4 is assembled with the water storage bin 2, the positioning column 42 abuts against the limiting position on the water storage bin 2, thereby achieving the abutment limiting of the front cover 4 and the water storage bin 2, and the mounting column 41 is fixedly connected with the water storage bin 2. Since the positioning column 42 is not touched by the ejection mechanism in the demolding process, the design height of the positioning column 42 can be ensured not to be affected by the demolding process, thereby ensuring that the relative position of the front cover 4 and the water storage bin 2 meets the design requirements.

[0039] In an embodiment, the circumferential side wall of the bin barrel 22 is provided with a protrusion to form a abutting position, the positioning column 42 abuts against the protrusion to realize the abutting limiting of the front cover 4 and the water storage bin 2.
