[0028] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0029] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides an ultrasonic handheld food cutter, comprising a handle 100 , an ultrasonic transducer 200 and a cutter body 300 .

[0030] The handle 100 is provided with a receiving cavity, and the ultrasonic transducer 200 is installed in the receiving cavity. One end of the cutting blade body 300 is provided with a connector 310 that penetrates from one end of the handle 100 and is connected to the ultrasonic transducer 200.

[0031] An annular connecting portion 210 is provided outside the ultrasonic transducer 200, and a gap is formed between the annular connecting portion 210 and the ultrasonic transducer 200. One end of the annular connecting portion 210 is connected to the outside of the ultrasonic transducer 200, and the annular connecting portion 210 is fixed in the accommodating cavity through a vibration-damping support mounting member 400.

[0032] The present application sets an annular connecting portion 210 outside the ultrasonic transducer 200, and there is a gap between the annular connecting portion 210 and the ultrasonic transducer 200, which can reduce the ultrasonic vibration generated by the operation of the ultrasonic transducer 200 from being transmitted to the annular connecting portion 210. At the same time, the annular connecting portion 210 is fixed in the accommodating cavity by the vibration-damping support mounting member 400, which can further reduce the vibration transmitted to the handle 100. Therefore, the present application can reduce the vibration of the ultrasonic transducer 200 from being transmitted to the handle 100, thereby reducing the heat generated by the handle 100 and improving the comfort of use.

[0033] In some embodiments, the handle 100 is composed of a first handle segment 110 and a second handle segment 120. The interface end of the first handle segment 110 is provided with an internal thread interface, and a limiting portion 111 is provided in the accommodating cavity of the handle 100 segment near the inner end of the internal thread interface.

[0034] The vibration-damping support mounting member 400 includes a vibration-damping ring 410 and a fastening ring 420. The vibration-damping ring 410 is threadedly connected to the internal thread interface. The inner end of the vibration-damping ring 410 is limited to the limiting portion 111. The inner end of the annular connecting portion 210 is connected to the outside of the ultrasonic transducer 200. The outer end of the annular connecting portion 210 is provided with an outer convex ring 211 limited to the outer end of the vibration-damping ring 410. The fastening ring 420 is threadedly connected to the vibration-damping ring 410 and the outer convex ring 211 is pressed against the outer end of the vibration-damping ring 410 through the shock-absorbing pad 430.

[0035] During assembly, first tighten the vibration damping ring 410 to the outside of the annular connecting part 210 of the ultrasonic transducer 200, then screw the vibration damping ring 410 into the internal thread interface of the first handle section 110, and then place the vibration damping pad 430 on the outer end of the outer convex ring 211 of the annular connecting part 210, and finally screw in the fastening ring 420 and press it against the outside of the vibration damping pad 430 to complete the assembly between the ultrasonic transducer 200 and the handle 100.

[0036] The annular connecting portion 210 of the assembled ultrasonic transducer 200 is fixed in the vibration-damping ring 410 . The vibration-damping ring 410 has a good vibration-damping and buffering effect. The soft connection between the ultrasonic transducer 200 and the handle 100 can reduce the vibration of the ultrasonic transducer 200 from being transmitted to the handle 100 .

[0037] In addition, one end of the vibration-damping ring 410 is limited by the limiting portion 111, and the other end is locked with the outer convex ring 211 by the fastening ring 420, which can prevent the vibration-damping ring 410 and the handle 100 and the vibration-damping ring 410 and the annular connecting portion 210 from shifting during operation. The fastening ring 420 and the handle 100 are hard-connected, and a vibration-damping pad 430 is arranged between the fastening ring 420 and the outer convex ring 211, which can reduce the vibration transmitted to the fastening ring 420 and then to the handle 100.

[0038] Optionally, the vibration-damping ring 410 and the shock-damping pad 430 are both made of red steel paper, which has excellent elasticity, mechanical strength, insulation performance and mechanical processing and forming performance.

[0039] Optionally, in order to facilitate the splicing between the first handle segment 110 and the second handle segment 120, the interface end of the second handle segment 120 is provided with an external thread interface that is threadedly connected to the internal thread interface.

[0040] In some embodiments, a rear cover 130 is provided at the rear end of the handle 100, and the rear cover 130 is threadedly connected to the handle 100. The rear cover 130 is provided with a threading hole 131 for the cable of the ultrasonic transducer 200 to pass through, so as to facilitate wiring. The rear cover 130 is provided with heat dissipation holes 132 around the threading hole 131 to improve the heat dissipation effect of the handle 100.

[0041] In some embodiments, the connector 310 and the handle 100 are supported by an elastic ring 500, and the cutting knife body 300 is supported by the elastic ring 500 of the connector 310, which can prevent the cutting knife body 300 from being unstable and the cutting knife body 300 from being in hard contact with the handle 100 during cutting.

[0042] Optionally, in order to facilitate the installation of the elastic ring 500, a front cover 140 is provided at the front end of the handle 100, and the front cover 140 is threadedly connected to the handle 100. A through hole 141 is provided on the front cover 140 for the cutting knife body 300 to pass through. An annular step 121 is provided at the front end of the handle 100 near the accommodating cavity side, and the elastic ring support 500 is positioned in the annular step 121 through the front cover 140. The connecting head 310 of the cutting knife body 300 is provided with an annular groove 311 on the outside for cooperating with the elastic ring 500.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
