Further, the tip assembly 10 further includes a sealing ring 162, and the sealing ring 162 is disposed in the mounting hole 161 and sleeved on the flow guide tube 50 to prevent liquid leakage or air leakage at the joint of the flow guide tube 50 and the axial hole 16.
In this embodiment, the top hole 17 is inclined backward with respect to the axial hole 16, and since the water flow has forward inertia during flushing, the inclined arrangement of the top hole 17 can effectively prevent the water flow from being ejected from the suction port 12 at the top end, which may cause misoperation. In addition, the lateral hole 18 is flush with the axial hole 16, the tip assembly 10 further includes a ventilation mesh cover 181, the ventilation mesh cover 181 covers the suction port 13 on the side, and the aperture of the air hole on the ventilation mesh cover 181 is set slightly larger than the smoke dust, so that the smoke can freely pass through the ventilation mesh cover 181, and the water can only slightly seep out, and the water flow has forward inertia during flushing, thereby the ventilation mesh cover 181 can effectively prevent the water flow from being ejected from the suction port 13 on the side, which causes misoperation.
Optionally, the tip assembly 10 further includes a heat dissipating member 19, the heat dissipating member 19 is disposed at the bottom of the tip body 15 and connected to the base 14, the base 14 is made of a heat conducting and dissipating material, it should be noted that, during the operation, the cutter head may be scalded due to energy (radio frequency or ultrasound), in order to avoid the generated heat from melting, blocking and deforming the tip body 15, the heat dissipating member 19 is disposed in the device, the heat dissipating member 19 may conduct the heat to the air or the base 14 connected thereto, and the base 14 is made of a heat conducting and dissipating material, which is beneficial for conducting the heat to the air, wherein the heat dissipating member 19 may be made of aluminum with high plasticity and low cost.
Optionally, a first groove 21 for inserting the cutter bar is formed at a position, close to the cutter bar, of the bottom of the direction-changing adjusting piece 20, and a second groove 191 for inserting the cutter bar is formed at a position, close to the cutter bar, of the bottom of the head assembly 10, so that the direction-changing adjusting piece can be stably matched with the cutter bar during installation. Correspondingly, the draft tube 50 is fixedly laid on the bottom of the first groove 21, and the laying mode can be gluing or potting.
