Detailed Description

The structure of the present invention will be further described with reference to the accompanying drawings and preferred embodiments of the present invention.

Referring to fig. 1 to 5, the utility model discloses a hand-held food cutting device, including food cutter 1, connect food cutter 1's ultrasonic transducer 2 to and handle portion 3 with ultrasonic transducer 2 erection joint.

The food cutter 1 is preferably made of food-grade titanium alloy material; in order to facilitate the uniform ultrasonic vibration, the food cutter 1 changes the existing single-sided blade into a double-sided blade, and through the analysis of computer finite element software, the uniformity of the ultrasonic vibration is greatly improved and the heat loss is greatly reduced compared with the single-sided blade.

The ultrasonic transducer 2 adopts the oscillation frequency of about 28KHz, transmits ultrasonic waves to the food cutter 1 through a screw surface, amplifies the amplitude of the acoustic waves by the same principle as the conventional ultrasonic cutting device arranged on a production line through the focusing of an arc surface part and an oblique angle, the cutting edge generates longitudinal vibration in the length direction, and mechanical energy is mainly concentrated to the cutting edge part to realize the functions of cutting and sealing edges at the same time; the side wall of the ultrasonic transducer is provided with an annular boss 21.

The handle part 3 comprises a front cover 31, a handle front part 32, a handle rear part 33 and a rear cover 34, the handle front part 32 and the handle rear part 33 are in threaded connection to form a handle main body 30, the ultrasonic transducer 2 is arranged in an inner cavity of the handle main body 30, a clamping boss 331 is arranged on the inner wall of the handle rear part 33, a first vibration damping part 4 is arranged between the clamping boss 331 and the upper surface of the annular boss 21, a second vibration damping part 5 is arranged between the end surface of the handle front part 32 and the lower surface of the annular boss 21, and in the process of screwing the handle front part 32 and the handle rear part 33 in a threaded fit mode, the end surface of the handle front part 32 and the clamping boss 331 on the inner wall of the handle rear part 33 clamp the annular boss 21 of the ultrasonic. In the specific implementation process, the second vibration damping piece 5 can be fixedly connected with the internal thread on the inner wall of the handle rear part 33 through matching of external threads and internal threads, and in order to drive the second vibration damping piece 5, a driving hole 51 is formed in the end face of the second vibration damping piece 5; the second vibration damper 5 is preferably in clearance fit with the outer wall of the ultrasonic transducer 2, and the ultrasonic transducer is clamped and fixed by the annular boss 21; similarly, the outer wall of the ultrasonic transducer 2 is in clearance fit with the front handle part 32 and the inner wall of the front cover 31, and the outer wall of the ultrasonic transducer 2 is also in clearance fit with the rear handle part 33.
