[0011] Beneficial effects of the present invention:

[0012] The circular saw blade hand-held electric saw of the present invention is equipped with a saw blade processing device through the outer side of the mounting block. During the working process, the saw blade rotates and cuts at high speed and the metal conducts heat, so that the surface of the circular saw blade will generate high temperature, and the cutting debris is easily adsorbed on the surface of the saw blade and the tooth structure at high temperature. The half-package processing shell is used to spray water from the shaft position, so that the high-speed rotating swing effect of the saw blade is combined with the water sprayed from the center to form a flushing effect with a lateral impact force on the surface of the saw blade. At the same time, the internal brush structure is combined to achieve a scraping and loosening effect on the debris adsorbed on the tooth internal structure. At the same time, the brush structure is wetted with water flow to form an effective cooling effect on the internal structure of the tooth. Therefore, while effectively controlling the temperature of the saw blade, the water flow impact effect enables a large amount of debris adsorbed on the surface of the saw blade to be cooled and removed, so that the debris is adsorbed on the side wall magnetic ring of the half-package processing device in combination with the swinging effect, so as to achieve the effect of suppressing the temperature of the saw blade and cooling and flushing the debris.

[0013] A circular saw blade hand-held electric saw of the present invention is provided with a saw blade processing device. In the saw blade processing device, a double-sided processing shell is used to wrap the outer periphery of the center of the circular saw blade. The half-wrapping processing can prevent the problem of debris being thrown out and injuring people. A guide piece is arranged in an array in the double-sided processing shell. When the saw blade rotates and passes through, the guide piece tilted up and down slightly fits the saw blade plane, so that the debris remaining on the surface of the saw blade and the tooth structure surface is separated under the pushing and scraping effect through the high-speed rotation effect. At the same time, a recovery port is provided at the inclined end of the guide piece. The debris pushed and scraped slides along the upper side of the guide piece under the inertial force and the saw blade rotation effect, and enters the magnetic suction cavity through the recovery port, so as to achieve smooth and flat processing of the saw blade. At the same time, the guide piece is fitted to scrape off excess water stains on the surface of the saw blade, so as to avoid excessive water stains being thrown out during the processing process.

[0014] A circular saw blade handheld electric saw of the present invention is fixed to a mounting block through a saw blade processing device. During processing and use, the working state characteristics of the circular saw blade are applied without the need for an extra power source, so that the temperature of the working circular saw blade can be suppressed. The saw blade rotates first through a half-wrapped processing shell to output water flow, which has a flushing and cooling effect on the saw blade. The half-wrapped structure allows the water to be thrown out to cool and moisten the lower surface of the saw blade and quickly discharge waste water. The double-sided processing shell is used to remove debris and excess water stains on the surface of the circular saw blade, so that the circular saw blade can always remain smooth and flat during the rotation processing process, thereby improving its cutting effect and avoiding the problem of high temperature of the saw blade affecting the life of its tooth structure.

[0023] During operation, the power motor 12 is started, and the circular saw blade 28 is driven by the tooth structure to rotate at high speed for cutting. During the rotation process, the water input end transmits the water flow through the water spray semi-ring 33 for output, so that the saw blade is flushed with water in a semi-ring shape near the center. With the high-speed rotation effect of the saw blade, the impact force of the water flow flushing on the saw blade is increased and flushed outward, thereby quickly suppressing the temperature of the saw blade. At the same time, the flushing effect reduces the temperature and adhesion of the debris on the surface of the saw blade. The loose debris is adsorbed on the adsorption magnetic ring 37 under the flushing of water and the scraping of the brush 46. The brush is made of non-metallic material with moderate hardness, which can scrape and loosen the debris in the teeth to avoid friction and heat generation with the saw blade. At the same time, the brush encounters water It has a certain moist storage effect, which improves the cooling effect of the brush and the tooth internal structure. Excess water flows through the inclined drain end 45 to the lower surface of the saw blade for flushing and discharge, ensuring the cooling effect of the saw blade tooth end. At the same time, it rotates through the double-sided processing shell 38, and through the inclined push-out piece 40, it can achieve the upper and lower surfaces of the saw blade to achieve the debris push and remove the excess water stains. The fallen debris slides along the upper side of the push-out piece 40 under the inertial force and the saw blade rotation effect, and then enters the magnetic suction cavity 41 through the recovery port 42, thereby achieving smooth and flat processing of the saw blade, so that the circular saw blade can always maintain a smooth and flat state during the rotation processing, improve its cutting effect and avoid the problem of high temperature of the saw blade affecting the life of its tooth structure.
