As shown in fig. 11, in some exemplary embodiments, an exhaust sleeve 152 is disposed in the exhaust port 104, an upper end of the exhaust sleeve 152 is located outside the housing 100, a lower end of the exhaust sleeve 152 is located inside the housing 100, a bottom surface of the exhaust sleeve 152 is higher than a top surface of the first operation port 110, a space is formed between an outer side surface of the exhaust sleeve 152 and an inner side surface of the housing 100, a lower end side wall of the exhaust sleeve 152 is parallel to the inner side surface of the housing 100, an upper end side wall of the exhaust sleeve 152 is vertically disposed, and the exhaust sleeve 152 is fixedly connected with the housing 100.
The dashed arrow in fig. 11 is a flow path of the air flow, and when welding inside the cover body 100, hot air is generated to rise, so that the air inside the cover body 100 is collected towards the air outlet 104, and because the inner space of the cover body 100 is conical, when rising, the air inside the cover body 100 has a movement trend towards the central axis of the cover body 100, most of the hot air is discharged from the air outlet sleeve 152, so that a negative pressure area (air pressure reduction) is generated between the outer side surface of the air outlet sleeve 152 and the inner side surface of the cover body 100, a part of the air outside the cover body 100 is sucked from the air outlet 104 outside the air outlet sleeve 152, and the other part of the air is sucked from the second beam port 126 and the third beam port 134, and then is intensively discharged from the air outlet sleeve 152 after being mixed with the internal hot air, so as to form a continuous directional air flow, which is helpful for the exhaust gas and heat dissipation inside the cover body 100 (the exhaust gas too much may interfere with the observation line).
In some exemplary embodiments, a plurality of telescopic rods 154 are arranged between the exhaust port 104 and the upper end of the exhaust sleeve 152, each telescopic rod 154 is arranged around the center of the exhaust port 104, one end of each telescopic rod 154 is hinged with the outer side surface of the upper end of the exhaust sleeve 152, the other end of each telescopic rod 154 is hinged with the upper end of the cover body 100, the telescopic rods 154 are obliquely arranged, and one end of each telescopic rod 154 close to the exhaust sleeve 152 is higher than the other end.
By vertically pushing and pulling the exhaust sleeve 152, the distance between the outer side surface of the lower end of the exhaust sleeve 152 and the inner side surface of the cover body 100 can be changed, so that the air flow of the gap is changed, when the air flow of the gap is reduced, the air flow of the second beam port 126 and the third beam port 134 can be increased (the total amount can be reduced), therefore, the effect of adjusting the air inlet direction and the air inlet amount can be achieved by adjusting the distance of the gap, when the waste gas in the cover body 100 is not much, the gap is closed, the total air inlet amount is reduced, the windproof effect is improved, and when the waste gas in the cover body is more, the gap is increased, and the air outlet efficiency is improved.
