Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic therapy, in particular to an ultrasonic therapy head. Background Art
[0002] In recent years, non-invasive beauty technology using focused ultrasound has been widely used. The principle is that the transducer installed inside the treatment head emits focused ultrasound. After the focused ultrasound is transmitted through the liquid conductor, it is focused on the subcutaneous tissue or fat tissue and forms a "high temperature point" on the local subcutaneous tissue or fat tissue, so that the local subcutaneous tissue shrinks under the action of high temperature, thereby achieving the beauty effect of improving skin firmness and losing weight.
[0003] The transducer is installed in the water storage chamber of the treatment head. In order to ensure that the liquid in the water storage chamber does not leak, a waterproof rubber ring is needed to seal the water storage chamber. However, the traditional waterproof rubber ring is usually designed with a smooth surface. During assembly, there is a gap between the smooth surface and the fitting surface of the waterproof rubber ring, which leads to the risk of leakage. Utility Model Content

[0025] The utility model provides an ultrasonic treatment head 200 to improve the sealing performance of the waterproof rubber ring 100 therein.
[0026] See also Figure 1 and Figure 2 The ultrasonic treatment head 200 includes a shell assembly and a waterproof rubber ring 100. The shell assembly includes a transducer bracket 22 and an inner shell 21 covering one side of the transducer bracket 22. The inner shell 21 and the transducer bracket 22 enclose a water storage cavity, and the water storage cavity is filled with a sound-conducting medium. The waterproof rubber ring 100 is sandwiched between the inner shell 21 and the transducer bracket 22. The waterproof rubber ring 100 has a first surface 11 and a second surface 13 opposite to each other. The first surface 11 is convexly provided with a plurality of annularly arranged first ribs 12, and the second surface 13 is convexly provided with a plurality of annularly arranged second ribs 14. The first surface 11 and the transducer bracket 22 are mutually fitted, and the second surface 13 and the end wall of the inner shell 21 are mutually fitted, and the first surface 11 and / or the second surface 13 are also convexly provided with a flange 15, which is arranged along the inner edge of the waterproof rubber ring 100 and is fitted and limited with the inner wall surface of the shell assembly.
[0027] The waterproof rubber ring 100 used in the conventional ultrasonic therapy head 200 is usually designed with a smooth surface. When assembled, there is a gap between the smooth surface and the fitting surface of the waterproof rubber ring 100, which leads to the risk of leakage. The waterproof rubber ring 100 used in the ultrasonic therapy head 200 of the utility model has a first convex rib 12 protruding from the first surface 11 and a second convex rib 14 protruding from the second surface 13. Therefore, when the waterproof rubber ring 100 is sealed and waterproof, the first surface 11 and the transducer bracket 22 are fitted together, the second surface 13 and the end wall of the inner shell 21 are fitted together, and the first convex rib 12 and the transducer bracket 22 are pressed against each other, and the second convex rib 14 and the end wall of the inner shell 21 are pressed against each other, so that liquid cannot leak out from the gap between the surface and the fitting surface of the waterproof rubber ring 100, thereby improving the sealing performance of the waterproof rubber ring 100.
[0028] At the same time, since the waterproof rubber ring 100 is usually made of rubber, it is easy to twist during the assembly process and then become loose or shifted, which in turn causes water leakage. For this reason, the technical solution also provides a protruding flange 15 on the first surface 11 and / or the second surface 13 of the waterproof rubber ring 100. The flange 15 is arranged along the inner edge of the waterproof rubber ring 100. When in use, the outer surface of the flange 15 and the inner wall surface of the docking shell are fitted and limited to each other, and since the flange 15 is annular in design, the waterproof rubber ring 100 can be prevented from twisting at any position, thereby avoiding water leakage caused by loosening and shifting of the waterproof rubber ring 100.
[0029] In addition, since the ultrasonic therapy head generates a large amount of heat in operation, the sound-conducting medium changes in volume due to thermal expansion and contraction, which may generate additional force on the waterproof rubber ring 100, causing the waterproof rubber ring 100 to move and leak. By providing a flange structure, the displacement of the waterproof rubber ring can be limited in a direction parallel to the waterproof rubber ring, thereby improving the reliability of the seal.
[0030] In one embodiment, the cross section of the first convex rib 12 and / or the second convex rib 14 gradually shrinks from the fixed end to the free end, the fixed end refers to the end connected to the ring body, and the free end is the end away from the ring body. For example, the cross section of the first convex rib 12 is one of a triangle, a trapezoid and a semicircle, and the cross section of the second convex rib 14 is also one of a triangle, a trapezoid and a semicircle. Among them, the cross sections of the first convex rib 12 and the second convex rib 14 can be consistent or inconsistent. The cross section of the first convex rib 12 and / or the second convex rib 14 gradually shrinks from the fixed end to the free end, which can reduce the contact area between the most convex point of the first convex rib 12 and / or the second convex rib 14 and the fitting surface, thereby increasing the pressure between the convex rib and the fitting surface, so that the first convex rib 12 and / or the second convex rib 14 are squeezed more tightly with the fitting surface, further increasing the sealing performance of the waterproof rubber ring 100.
[0031] Preferably, the cross-sections of the first rib 12 and the second rib 14 are both isosceles triangles. In this case, the forces on both sides of the most convex points of the first rib 12 and the second rib 14 are uniformly applied, and the combined forces on both sides just act on the most convex points, achieving the best sealing effect.
[0032] It should be noted that the waterproof rubber ring 100 does not limit the number of the first convex ribs 12 and the second convex ribs 14. The first convex ribs 12 and the second convex ribs 14 can be provided with one, two or three circles, etc., respectively, and the number of the first convex ribs 12 and the second convex ribs 14 can be the same or different. The more convex ribs there are, the better the waterproof performance. At the same time, in order to avoid a large extrusion deformation of the ring body, the number of convex ribs should not be too many. For example, in the embodiment shown in the figure, the first surface 11 is provided with two circles of the first convex ribs 12 protruding upward, and the second surface 13 is provided with one circle of the second convex ribs 14 protruding downward.
[0033] Preferably, the protruding heights of the first convex rib 12 and the second convex rib 14 are consistent, so that the extrusion amounts on both sides of the waterproof rubber ring 100 are equal.
[0034] It is worth mentioning that the waterproof rubber ring 100 has at least one pair of first convex ribs 12 and second convex ribs 14 arranged opposite to each other. When the number of the first convex ribs 12 and the second convex ribs 14 is the same, each first convex rib 12 is arranged opposite to a second convex rib 14. When the first surface 11 is provided with two circles of first convex ribs 12 and the second surface 13 is provided with one circle of second convex ribs 14, one circle of first convex ribs 12 is arranged opposite to the second convex ribs 14, and the other circle of first convex ribs 12 is arranged offset from the second convex ribs 14. The first convex ribs 12 and the second convex ribs 14 are arranged opposite to each other. On the one hand, the thickness of the ring body at this position can be increased to reduce the extrusion deformation of the ring body. On the other hand, the extrusion forces of the first convex ribs 12 and the second convex ribs 14 can be made collinear, and there is no moment of force on the ring body at this position, thereby avoiding the ring body from bulging.
[0035] In one embodiment, the first surface 11 and / or the second surface 13 of the waterproof rubber ring 100 may be concavely provided with a water retaining groove 16, and the water retaining groove 16 is located in the inner circle of the convex rib on the same side. A first retaining edge 211 is convexly provided on one side of the transducer bracket 22 facing the inner shell 21 and / or on the end surface of the inner shell 21 facing the transducer bracket 22, and the first retaining edge 211 is inserted into the water retaining groove 16, and the end surface of the first retaining edge 211 and the bottom wall of the water retaining groove 16 are pressed against each other, thereby forming a water retaining barrier, and the water retaining groove 16 and the convex rib on the same side work together to form multiple water retaining barriers, further improving the sealing effect.
[0036] At this time, the convex rib on the other surface is arranged opposite to the water retaining groove 16, and the oppositely arranged convex rib and the first retaining edge 211 of the shell to be sealed push each other, so as to further ensure the sealing effect.
[0037] Furthermore, the end surface of the inner shell 21 facing the transducer bracket 22 is also convexly provided with a second rib 212 surrounding the outer periphery of the first rib 211, and the inner side surface of the second rib 212 is arranged in contact with the outer side surface of the waterproof rubber ring 100, further ensuring the sealing performance. In a natural state, the first surface 11 of the waterproof rubber ring 100 is arranged flush with the top surface of the second rib 212, or the height of the first surface 11 of the waterproof rubber ring 100 beyond the second rib 212 is not more than 2mm, thereby preventing the waterproof rubber ring 100 from generating a large compression deformation when being squeezed by the transducer bracket 22 and the inner shell 21.
[0038] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
