Technical Field
[0001] The utility model relates to the technical field of ultrasonic therapy, in particular to a handheld ultrasonic therapy instrument. Background Art
[0002] The working principle of the ultrasonic therapeutic device is to emit focused ultrasonic waves through the transducer installed inside the treatment head. After the focused ultrasonic waves are transmitted through the liquid conductor, they are focused on the subcutaneous tissue or fat tissue, and form a "high temperature point" on the local subcutaneous tissue or fat tissue, thereby causing the local subcutaneous tissue to contract under the action of high temperature and thus achieve the cosmetic effect of improving skin firmness and losing weight.
[0003] Since the feedback effect of skin layers at different depths on thermal effects is different, the height of the transducer needs to be adjusted during the treatment process to adapt to the treatment needs of skin layers at different depths. At present, the control of the transducer height mainly relies on the output shaft of the motor to drive the transducer up and down, but the axis direction of the motor is usually consistent with the direction of the up and down movement of the transducer, which leads to a high height and large size of the treatment head.

[0027] The present utility model provides a handheld ultrasonic therapeutic apparatus 100.
[0028] Please refer to Figures 1 to 4 , the embodiment of this handheld ultrasonic therapeutic apparatus 100 includes a handle 1 and a treatment head 3. A driving member 2 is arranged inside the handle 1. The driving member 2 has a driving end 21. The treatment head 3 is arranged at one end of the handle 1. A transducer unit 4 and a transmission shaft 6 drivingly connected to the transducer unit 4 are arranged inside the treatment head 3. Among them, the driving end 21 is arranged along a first direction, the transmission shaft 6 is arranged along a second direction, and the first direction and the second direction are arranged at an angle. A transmission mechanism 5 is arranged between the driving end 21 and the transmission shaft 6. The transmission mechanism 5 is used to transmit the movement of the driving end 21 to the transmission shaft 6, thereby driving the transducer unit 4 to move up and down.
[0029] The handheld ultrasonic therapeutic apparatus 100 is in the shape of a pistol as a whole, and includes a handle 1 and a treatment head 3 arranged at the end of the handle 1. The angle between the handle 1 and the treatment head 3 ranges from 90° to 135°, which is convenient for users to hold and use. At present, the control of the height of the transducer unit 4 by the ultrasonic therapeutic apparatus mainly relies on the output shaft of the motor to drive the transducer 42 to move up and down, and the output shaft is usually coaxially arranged with the axis of the transducer 42, which leads to a high height and a large size of the treatment head 3. Different from the traditional ultrasonic therapeutic apparatus, the handheld ultrasonic therapeutic apparatus 100 arranges the transducer unit 4 and the transmission shaft 6 connected to the transducer unit 4 in the treatment head 3, arranges the driving member 2 in the handle 1, and makes the driving end 21 of the driving member 2 and the transmission shaft 6 arranged at an angle. Among them, the driving end 21 of the driving member 2 is arranged along the first direction, and the first direction can be the axial direction of the handle 1, or a direction that presents a certain angle with the axial direction of the handle 1, as long as the driving member 2 can be arranged in the handle. The transmission shaft 6 is arranged along the second direction, which is the axial direction of the treatment head, so that the transmission shaft 6 can drive the transducer unit 4 to move toward or away from the sound-transmitting port to achieve multi-depth treatment. Then, the transmission mechanism 5 is arranged between the driving end 21 and the transmission shaft 6 to transmit the movement of the driving end 21 to the transmission shaft 6, thereby driving the transducer unit 4 to move up and down. The handheld ultrasonic therapeutic device 100 changes the arrangement direction of the driving member 2, reduces the space occupied by the treatment head 3 in the height direction, and thus reduces the longitudinal size of the product.
[0030] In the embodiment shown in the figure, the driving member 2 is a motor, and the rotating shaft of the motor is the driving end 21. Figure 1 and Figure 2 In the illustrated embodiment, the transmission mechanism 5 includes a worm 51 and a gear 52 meshing with each other, the worm 51 is coaxially arranged and fixedly connected with the driving end 21, and the gear 52 is sleeved on the transmission shaft 6 and fixedly connected with the transmission shaft 6. Therefore, the rotation of the motor will drive the driving end 21 to rotate, the rotation of the driving end 21 will drive the worm 51 to rotate, the rotation of the worm 51 will drive the gear 52 to rotate, the rotation of the gear 52 will drive the transmission shaft 6 to rotate, the rotation of the transmission shaft 6 will drive the transducer unit 4 to move up and down, thereby realizing the function of adjusting the focal plane distance of the transducer unit 4.
[0031] exist Figure 3 and Figure 4In the embodiment shown, the transmission mechanism 5 includes a first bevel gear 53 and a second bevel gear 54 that mesh with each other. The first bevel gear 53 is coaxially arranged and fixedly connected with the driving end 21, and the second bevel gear 54 is coaxially arranged and fixedly connected with the transmission shaft 6. Specifically, a first center hole is provided at the center of the first bevel gear 53, and the driving end 21 is inserted into the first center hole to be welded and fixed with the first bevel gear 53. A second center hole is provided at the center of the second bevel gear 54, and the transmission shaft 6 is inserted into the second center hole to be welded and fixed with the second bevel gear 54. Thus, the rotation of the motor will drive the driving end 21 to rotate, and the rotation of the driving end 21 will drive the first bevel gear 53 to rotate, and the rotation of the first bevel gear 53 will drive the second bevel gear 54 to rotate, and the rotation of the second bevel gear 54 will drive the transmission shaft 6 to rotate, and the rotation of the transmission shaft 6 will drive the transducer unit 4 to move up and down, thereby realizing the function of adjusting the focal plane distance of the transducer unit 4. In this embodiment, two bevel gears 52 are meshed, which can make the space occupied by the transmission mechanism 5 smaller, thereby reducing the size of the entire handheld ultrasonic therapeutic device 100 accordingly, and further realizing the miniaturized design of the product.
[0032] Among them, when the number of teeth of the first bevel gear 53 is consistent with the number of teeth of the second bevel gear 54, the rotation speed of the second bevel gear 54 is equal to that of the first bevel gear 53; when the size of the first bevel gear 53 is smaller than that of the second bevel gear 54 and the number of teeth of the first bevel gear 53 is less than that of the second bevel gear 54, the rotation speed of the second bevel gear 54 can be reduced to achieve a slight adjustment of the height of the transducer unit 4 and improve the accuracy of the height adjustment of the transducer unit 4; when the size of the first bevel gear 53 is larger than that of the second bevel gear 54 and the number of teeth of the first bevel gear 53 is more than that of the second bevel gear 54, rapid adjustment of the transducer unit 4 can be achieved.
[0033] Regarding the connection between the energy conversion unit 4 and the transmission shaft 6, refer to Figure 1 or Figure 3 The end of the transmission shaft 6 facing away from the transmission mechanism 5 is sleeved with a shaft sleeve 7, and the end of the shaft sleeve 7 facing the transducer unit 4 is protrudingly provided with a sleeve 71. The transducer unit 4 includes a transducer 42 bracket and a transducer 42 mounted on the transducer 42 bracket. The end of the transducer 42 bracket facing the transmission shaft 6 is protrudingly provided with a connecting shaft 43, and the connecting shaft 43 is inserted into the sleeve 71 to be rotatably connected with the transmission shaft 6. The rotation of the transmission shaft 6 drives the connecting shaft 43 to move up and down.
[0034] For example, an inner side wall of the sleeve 71 is provided with an internal thread, a peripheral side wall of the connecting shaft 43 is provided with an external thread, and the connecting shaft 43 is inserted into the sleeve 71 to be threadedly connected with the sleeve 71 .
[0035] Thus, the rotation of the driving member 2 will drive the rotation of the driving end 21. The rotation of the driving end 21 will drive the movement of the transmission mechanism 5. The movement of the transmission mechanism 5 will drive the rotation of the transmission shaft 6. The rotation of the transmission shaft 6 will drive the up and down movement of the connecting shaft 43, thereby realizing the up and down adjustment of the transducer unit 4.
[0036] In addition, in the present handheld ultrasonic therapeutic apparatus 100, the treatment head 3 includes an inner shell 31 and an outer shell 32. The inner shell 31 is detachably disposed in the chamber of the outer shell 32. The inner shell 31 is filled with an acoustic medium. The transducer unit 4 is disposed in the inner shell 31. The sleeve 71 is passed through the inner shell 31 to be connected to the connecting shaft 43. The transducer unit 4 is immersed in the acoustic medium, and the ultrasonic wave emitted by it is transmitted to the skin tissue after being conducted through the acoustic medium and acting on the sound transmission window, thereby achieving a therapeutic effect. In order to prevent the acoustic medium from leaking out from the connection between the inner shell 31 and the sleeve 71, a sealing ring 8 is sleeved on the sleeve 71, and the sealing ring 8 is located at the connection between the sleeve 71 and the inner shell 31.
[0037] Wherein, the handle 1 and the outer shell 32 are detachably connected, such as magnetic connection or snap connection, etc., so as to facilitate the assembly of the inner shell 31.
[0038] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
