[0037] Please refer to Figure 2 and Figure 3 One embodiment of the present application provides an ultrasonic cutting knife, comprising a shell 100, a transducer, a knife head 200 and a light emitting piece 300, the shell 100 has a mounting cavity 120 and a mounting port 110 connected; the transducer is arranged in the mounting cavity 120 and is provided with an output part; the knife head 200 has a mounting part 210 and a cutting part 220, the mounting part 210 is connected with the output part, and the cutting part 220 extends out of the shell 100 through the mounting port 110; the light emitting piece 300 is arranged in the mounting port 110 and faces the processing part of the material.

[0038] The mounting portion 210 of the ultrasonic cutting knife head 200 is connected with the output portion of the transducer in the mounting cavity 120. When the transducer operates, the cutting portion 220 outside the mounting cavity 120 can be driven to vibrate, and then the processing portion of the material is cut. During the cutting process, the light emitting member 300 arranged on the mounting port 110 can provide light to the processing portion of the material, so that the worker can obtain a clearer field of view. Compared with the traditional technology, the worker does not need to frequently move the direction of the desk lamp when using the ultrasonic cutting knife, and the processing portion of the material can be ensured to be sufficiently illuminated, thereby improving the work efficiency of the worker.

[0039] Further, the shell 100 is in a strip shape so as to be convenient for the worker to hold. In addition, the strip-shaped mounting cavity 120 can also match the shape of the transducer so as to facilitate the installation of the transducer. The mounting port 110 is arranged at one end of the strip-shaped shell 100 along the length direction of the shell 100, so that the knife head 200 can protrude out of the mounting cavity 120.

[0040] As an explanation, the transducer is an ultrasonic transducer. The ultrasonic transducer can convert electrical energy into mechanical energy, so as to drive the knife head 200 to vibrate.

[0041] In an embodiment, the output portion includes a horn. The knife head 200 is connected with the transducer through the horn. The horn can amplify the vibration amplitude generated by the transducer through the shape and material characteristics of the horn, so as to ensure that the knife head 200 can obtain sufficient vibration energy.

[0042] Further, the strip-shaped shell 100 can adapt to the shape of the horn so as to fully utilize the space of the mounting cavity 120.

[0043] In an embodiment, the mounting portion 210 includes a chuck 211. The cutting portion 220 is connected with the horn through the chuck 211. The vibration generated by the transducer is transmitted to the chuck 211 through the horn, and finally transmitted to the cutting portion 220, so as to cut the processing portion of the material.

[0044] Further, the cutting portion 220 is detachably connected with the chuck 211, so that the shape of the cutting portion 220 can be replaced according to specific use scenarios. For example, the cutting portion 220 can be a blade 221 in Figure 5 , or can be a grinding piece 222 in Figure 5 , which will not be described here again.

[0045] Optionally, the light emitting member 300 can be arranged at a position close to the mounting port 110 outside the shell 100, or can be arranged at a position close to the mounting port 110 in the mounting cavity 120, or can be arranged on the inner wall of the mounting port 110, which will not be specifically limited here.

[0046] Please refer toFigure 2 and Figure 4 In one embodiment, the light-emitting piece 300 comprises a mounting seat 310 and a first light-emitting part 320. The mounting seat 310 is arranged on the housing 100 and is provided with a mounting channel 311. The mounting channel 311 is in communication with the mounting port 110. The tool bit 200 is sequentially arranged in the mounting port 110 and the mounting channel 311. The cutting part 220 protrudes from the plane of the end of the mounting channel 311 away from the mounting port 110. The first light-emitting part 320 is arranged on the inner wall of the mounting channel 311 and is arranged towards the end of the mounting channel 311 away from the mounting port 110.

[0047] In this way, the first light-emitting part 320 can illuminate the machining part of the material through the mounting channel 311, preventing the light emitted by the first light-emitting part 320 from diverging. In addition, arranging the first light-emitting part 320 in the mounting channel 311 can also protect the first light-emitting part 320 from being damaged by external objects.

[0048] Further, the inner wall of the mounting port 110 and the inner wall of the mounting channel 311 are both arranged in a spaced manner, thereby leaving space for the vibration of the tool bit 200, preventing the tool bit 200 from touching the inner wall of the mounting port 110 or the mounting channel 311 when vibrating.

[0049] Referring to Figure 4 In one embodiment, the first light-emitting part 320 comprises a light-emitting ring 321. The outer ring surface of the light-emitting ring 321 abuts against the inner wall of the mounting channel 311. The inner ring surface of the light-emitting ring 321 surrounds the tool bit 200.

[0050] The mounting channel 311 of the mounting seat 310 can fix and protect the light-emitting ring 321. The light-emitting ring 321 surrounds the tool bit 200 to illuminate the periphery of the tool bit 200, ensuring that the worker's field of vision is clearer when cutting the machining part of the material.

[0051] Further, the connection between the outer ring surface of the light-emitting ring 321 and the inner wall of the mounting channel 311 can be adhesion, clamping, or the like, which is not limited here.

[0052] Referring to Figure 4 In one embodiment, the light-emitting ring 321 is provided with at least two illumination lamp beads 322 on the side away from the mounting port 110. All the illumination lamp beads 322 are arranged in a spaced manner along the circumference of the light-emitting ring 321. The first light-emitting part 320 further comprises an annular light uniformizing cover 323. The annular light uniformizing cover 323 surrounds the tool bit 200 and is arranged on the side of the light-emitting ring 321 away from the mounting port 110.

[0053] When the illumination lamp beads 322 emit light, the light will pass through the annular light uniform cover 323 and then irradiate to the processing part of the material. The annular light uniform cover 323 can not only uniformly process the light emitted by the at least two illumination lamp beads 322, but also prevent foreign matters from entering the installation channel 311 to damage the illumination lamp beads 322.

[0054] In one embodiment, the annular light uniform cover 323 is made of PC (Polycarbonate, polycarbonate), which has high light transmittance, high impact strength, high heat resistance and good insulation.

[0055] In one embodiment, the annular light uniform cover 323 is detachably arranged in the installation channel 311. In this way, the color of the light can be changed by replacing the annular light uniform cover 323 of different colors.

[0056] In Figure 4 In the embodiment shown, the illumination lamp is provided with four circumferentially spaced light emitting rings 321.

[0057] Further, the illumination lamp is an LED lamp bead.

[0058] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 In one embodiment, the ultrasonic cutting knife further comprises a cover 400, which is detachably arranged in the installation opening 110 and used to cover the cutting part 220. The cover 400 is provided with a locking part 410, and the mounting seat 310 is provided with a locking matching part 312. The locking part 410 is used to lock and match with the locking matching part 312.

[0059] When the ultrasonic cutting knife is in an idle state, the cover 400 is installed at the installation opening 110 and covers the cutting part 220 to prevent the cutting part 220 from cutting the workers. The locking part 410 on the cover 400 can lock and match with the locking matching part 312 on the mounting seat 310, which not only prevents the cover 400 from falling off, but also prevents the workers from being cut by mistakenly opening the cover 400.

[0060] Optionally, the locking mode between the locking part 410 and the locking matching part 312 can be snap connection, or can be connected through threaded rotation, etc., which is not limited here.

[0061] Please refer to Figure 6 In one embodiment, the locking part 410 comprises a sliding buckle 411, and the locking matching part 312 comprises a lock groove 313. The sliding buckle 411 can move and is used to lock or unlock the lock groove 313.

[0062] Further, the cover 400 and the mounting base 310 are closed in a threaded connection manner, when the cover 400 rotates to a preset position, the sliding buckle 411 corresponds to the lock groove 313, at this time, the worker moves the sliding buckle 411, so that the sliding buckle 411 enters the lock groove 313, which can prevent the cover 400 from rotating on the mounting base 310, thereby realizing the locking between the cover 400 and the mounting base 310.

[0063] Further, the cover 400 is provided with a sliding groove 420, the side wall of the sliding groove 420 is provided with a first limiting groove 421 and a second limiting groove 422, the first limiting groove 421 is located on the side of the second limiting groove 422 facing the lock groove 313, the side wall of the sliding buckle 411 is provided with a limiting protrusion 412, when the worker moves the sliding buckle 411 so that the limiting protrusion 412 is matched with the first limiting groove 421, the sliding buckle 411 enters the lock groove 313, when the worker moves the sliding buckle 411 so that the limiting protrusion 412 is matched with the second limiting groove 422, the sliding buckle 411 exits the lock groove 313.

[0064] Please refer to Figure 1 and Figure 7 In an embodiment, the ultrasonic cutting knife further comprises a switch mechanism 500 and a control mechanism 600, the switch mechanism 500 is arranged on the shell 100 and located outside the mounting cavity 120, the control mechanism 600 is arranged in the mounting cavity 120, and the switch mechanism 500 and the transducer are electrically connected with the control mechanism 600.

[0065] The control mechanism 600 can transmit the signal sent by the switch mechanism 500 to the transducer, so that the worker can control the operation of the transducer by controlling the switch mechanism 500 on the shell 100, thereby controlling whether the tool bit 200 operates.

[0066] Please refer to Figure 1 In an embodiment, the switch mechanism 500 comprises a pressing piece 510 and a gear adjusting piece 520, the pressing piece 510 and the gear adjusting piece 520 are arranged on the shell 100, and the gear adjusting piece 520 can reciprocate along the first direction of the shell 100.

[0067] The worker can control the output power of the transducer by moving the position of the gear adjusting piece 520, so as to adjust the vibration intensity of the tool bit 200; the worker can turn on or off the transducer by pressing the pressing piece 510, thereby improving the use convenience of the ultrasonic cutting knife.

[0068] As an explanation, the first direction of the shell 100 can also be the length direction, the width direction or the height direction of the shell 100, which is not limited here; in Figure 2In the embodiment shown, the housing 100 is a cuboid structure, the first direction of the housing 100 is the height direction of the housing 100 (i.e. Figure 2 the A direction in FIG. 1).

[0069] Further, in an embodiment, the gear adjusting member 520 has a manual gear, an automatic gear, and an off gear. When the ultrasonic cutting knife needs to be used, in order to prevent the knife head 200 from vibrating and injuring the worker, the worker adjusts the gear adjusting member 520 to the manual gear. In the manual gear mode, when the pressing member 510 is pressed, the transducer operates and drives the knife head 200 to vibrate, and when the pressing member 510 is not pressed, the transducer stops operating. This gear can effectively prolong the use time of the ultrasonic cutting knife. When the worker adjusts the gear adjusting member 520 to the automatic gear, the transducer continuously operates and drives the knife head 200 to vibrate. When the use is completed, the worker adjusts the gear adjusting member 520 to the off gear.

[0070] Still further, the manual gear can also be divided into multiple different modes. In different modes, the output power of the transducer is different, thereby achieving the effect of adjusting the vibration intensity of the knife head 200.

[0071] Please refer to Figure 7 In an embodiment, the control mechanism 600 is provided with a pressing control part 610 and a sliding control part 620, the housing 100 is provided with a pressing hole 131 and a strip-shaped hole 132, both the pressing hole 131 and the strip-shaped hole 132 are in communication with the mounting cavity 120, the pressing member 510 is arranged on the pressing control part 610 and penetrates the pressing hole 131, the second direction of the strip-shaped hole 132 is parallel to the first direction of the housing 100, and the gear adjusting member 520 is arranged on the sliding control part 620 and penetrates the strip-shaped hole 132. The gear adjusting member 520 can reciprocate along the second direction of the strip-shaped hole 132.

[0072] When the worker presses the pressing member 510, the pressing member 510 can move along the axis direction of the pressing hole 131, thereby triggering the pressing control part 610 on the control mechanism 600, so that the control mechanism 600 sends corresponding signals to the transducer and controls whether the knife head 200 vibrates. The worker controls the gear adjusting member 520 to move along the second direction of the strip-shaped hole 132, thereby triggering the sliding control part 620 on the control mechanism 600 to move, so that the control mechanism 600 sends corresponding signals to the transducer and controls the output power of the transducer, thereby controlling the vibration intensity of the knife head 200.

[0073] Further, the worker can control the gear adjusting key to reciprocate along the second direction of the strip-shaped hole 132, so as to adjust the ultrasonic cutting knife between the manual gear, the automatic gear, and the off gear.

[0074] As an explanation, the second direction of the bar hole 132 is the radial direction of the bar hole 132 (i.e. Figure 7 the B direction in the figure, which will not be described again here.

[0075] In one embodiment, the control mechanism 600 includes a first circuit board and a second circuit board, the pressing control part 610 is arranged on the first circuit board, and the sliding control part 620 is arranged on the second circuit board.

[0077] The second light-emitting part 630 can emit light of different colors according to the gear position of the transducer and the on-off state, the optical fiber irradiates to the outside through the light-transmitting part 511, and the staff can obtain the current state of the ultrasonic cutting knife through the color of the light-transmitting part 511 while pressing the pressing part 512, thereby improving the use convenience of the ultrasonic cutting knife.

[0078] Further, the light-transmitting part 511 is made of silica gel.

[0079] Please refer to Figure 7 In one embodiment, the second light-emitting part 630 is provided with at least two LED lamp beads, the LED lamp beads can display different colors, thereby indicating the current state of the ultrasonic cutting knife.

[0080] As an example, the second light-emitting part 630 is provided with two green LED lamp beads and two blue LED lamp beads, when the gear position of the transducer is adjusted to manual gear, the green LED lamp beads will emit light to make the light-transmitting part 511 display green when the pressing part 512 is pressed; when the gear position of the transducer is adjusted to automatic gear, the blue LED lamp beads will emit light to make the light-transmitting part 511 display blue without pressing the pressing part 512.
