DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, not all combinations of features described in the embodiments are necessarily required for the solution of the utility model.

[0020] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments. Example

[0021] like Figure 1 As shown, a welding tool includes an electrode holder, the electrode holder including an electrode holder body 1 and a handle 2 disposed on the electrode holder body 1 for grasping by a hand. The handle 2 has a cavity 3 therein and is provided with through holes 4 communicating with the cavity 3. The handle 2 is provided with a ventilation fan 5. The ventilation fan 5 allows external air to enter the cavity 3 and then be discharged from the through holes 4, thereby achieving air cooling for the handle 2. The ventilation fan 5 can be powered by a battery or by directing an external power source.

[0022] The ventilation fan 5 is disposed at an end of the cavity 3 away from the electrode holder body 1 , so that airflow enters from the end away from the electrode holder body 1 , thereby preventing the airflow from being heated by the electrode holder body 1 .

[0023] The end of the handle 2 is provided with a trumpet-shaped guide port 6 corresponding to the ventilation fan 5 , which prevents the airflow coming out of the through hole 4 from being directly and quickly sucked into the cavity 3 by the ventilation fan 5 , which is not conducive to the heat dissipation of the handle 2 .

[0024] Opposite the trumpet-shaped air guide port 6, an arcuate guide surface 7 is provided on the outer circumference of the other end of the handle 2, facing the handle 2. The arcuate guide surface 7 reflects the airflow discharged from the through hole 4 toward the hand grasping the handle 2, thereby facilitating hand cooling. A thermal insulation layer 8 is provided between the arcuate guide surface 7 and the electrode holder body 1 to prevent the temperature of the arcuate guide surface 7 from being increased by the electrode holder body 1.

[0025] The ventilation fan 5 is an axial flow fan, which has a simple structure and can generate a strong forward airflow. Specifically, the axial flow fan includes an impeller 9 and a motor that controls the rotation of the impeller 9. The motor is a hollow shaft motor, and the stator of the hollow shaft motor is fixedly connected to the end of the handle 2. The end of the handle 2 is provided with an air inlet 13 corresponding to the impeller 9.

[0026] The power supply line 10 of the welding torch passes through the cavity 3 in the handle 2, thereby supplying power to the welding torch body 1 to provide current for welding. The power supply line 10 passes through the hollow shaft of the motor.

[0027] The other end of the cavity 3 is provided with a cone 11 opposite to the ventilation fan 5. The surface of the cone 11 reflects the airflow from the ventilation fan 5 toward the through holes 4, so that the airflow flows out of each through hole 4 quickly and evenly. The power supply line 10 passes through the central axis of the cone 11.

[0028] The cone 11 is provided with a semiconductor cooling plate 12 to reduce the temperature of the cone 11 and thereby reduce the temperature in the cavity 3. The semiconductor cooling plate 12 and the ventilation fan 5 are powered by the same power supply so that the two operate synchronously.

[0029] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
