Description
Technical Field
[0001] The utility model belongs to the technical field of carving knives, and in particular relates to a dustproof jade carving knife. Background Art
[0002] With the advancement of jade carving techniques, the demand for precision and efficiency continues to increase, leading to the increasing popularity of electric jade carving knives. However, most electric jade carving knives currently on the market focus solely on the carving function itself, overlooking the crucial issue of dust generation during the carving process. Jade carving dust not only contains jade debris but also potentially tiny particles generated during the carving process. This airborne dust poses a serious health threat to the carver. Long-term inhalation of this dust can lead to respiratory diseases such as pneumoconiosis and bronchitis, as well as eye discomfort and skin allergies.
[0003] Existing simple dust prevention measures, such as using external vacuum cleaners, present numerous inconveniences. Firstly, these devices are bulky, restricting the engraver's movements and affecting the engraving's flexibility and precision. Secondly, the suction ports of some vacuum cleaners are located some distance from the engraving tool's working area, which can easily lead to the spread of large amounts of dust near the engraving area.

[0029] When in use, by holding the gripping portion 16 of the tool rod 11, ensure that the hand holds the engraving knife steadily, and press the start button 19 accordingly to start the second motor 131. The second motor 131 drives the connecting clip 17 and the engraving head 10 to rotate through the transmission shaft 132 to start the engraving operation; during the engraving process, the dust generated by the engraving will be sucked into the dust collection bin 14 by the air holes of the dust collection nozzle 151, and the first motor 141 is started by the corresponding start button 19 to drive the turbine 142 to rotate, thereby generating negative pressure inside the dust collection bin 14 to guide the dust to be sucked in. After entering the dust collection nozzle 151, the dust will first contact the front filter paper layer 1521 of the filter element 152, and be filtered by the filter paper. Some of the dust that passes through the filter paper will be adsorbed by the middle filter cotton layer 1522, purifying the output airflow and preventing the dust from affecting the surrounding area.
