Description

Technical Field

[0001] The utility model relates to the technical field of electric welding, in particular to an oxygen supply mask for welders. Background Art

[0002] When welding in plateau areas, workers' oxygen intake is insufficient due to physical labor and low oxygen content in the plateau. Therefore, it is necessary to install a supply device on the welding helmet. The existing solution connects the mask to the user's mouth and nose for supply. Although it increases the oxygen intake of workers, the humidity in the mask will increase during the worker's breathing due to poor ventilation, and then produce water droplets, which greatly affects the comfort of the wearer.

[0003] In addition, the smoke and dust generated during the welding process will cover the filter lens, which is inconvenient for the user to clean it thoroughly during work, and cleaning also affects work efficiency. Utility Model Content

[0016] Preferably, a battery is provided on the mask, and a control panel is provided on the front side of the shell.

[0017] The beneficial effects are:

[0018] 1. The outside air is drawn into the ventilation pipe through the fan, and the outside air enters the shell through the air vent for the user to breathe. The gas exhaled by the user can also be discharged through the ventilation pipe. By improving the ventilation, the heavy humidity in the shell is avoided, which affects the comfort of the user. Oxygen is released into the shell through the oxygen cylinder to increase the oxygen content of the gas inhaled by the user. At the same time, the speed of the fan is adjusted to ensure that the moisture in the shell does not affect the comfort of the user, and to avoid the rapid discharge of oxygen through the ventilation pipe, which causes waste;

[0019] 2. The cleaning component automatically cleans the dust on the filter lens surface to ensure that the welding operation can be carried out continuously without taking up the staff's time;

[0020] 3. The mask can be worn on the user's head by the elastic band and the support pad, and the elastic band can expand and contract with the size of the user's head. The expansion and contraction of the elastic band and the spring can further improve the adaptability of the mask to users with different head circumferences;

[0021] 4. Setting up a filter element can filter the exhaust gas generated by electric welding. By designing the ventilation pipe into an arc shape, it can prevent the smoke and dust generated during the electric welding process from directly entering the ventilation pipe.

[0029] See also Figure 1-Figure 3 As shown, the utility model provides an oxygen supply mask for welders, comprising a mask 1, on which a filter lens 2 and a cleaning component 3 for cleaning dust on the surface of the filter lens 2 are arranged;

[0030] The mask 1 is provided with a shell 6, and a sealing ring 16 is provided at the open edge of the shell 6. The sealing ring 16 can be extended and retracted to fit the user's mouth and nose. A ventilation pipe 8 is provided in the shell 6, and a portion of the ventilation pipe 8 passing through the shell 6 is provided with a plurality of air holes 15. A fan 9 is provided at one end of the ventilation pipe 8, and a filter element 10 for filtering welding fumes is provided at the air inlet of the fan 9.

[0031] The housing 6 is connected to an oxygen cylinder 12 via a hose 11 .

[0032] As an optional embodiment, the cleaning assembly 3 includes two electric push rods 4, which are arranged on the mask 1, and a scraper bar 5 is arranged between the movable ends of the two electric push rods 4. The scraper bar 5 is in contact with the filter lens 2. The scraper bar 5 is driven by the electric push rods 4 to move along the filter lens 2, so as to scrape off the dust on the surface of the filter lens 2.

[0033] The oxygen cylinder 12 is portable and releases oxygen by pressing a button on the top.

[0034] The ventilation pipe 8 is arc-shaped, and both ends are facing the back of the mask 1, so that the smoke generated during the electric welding process can be prevented from directly entering the ventilation pipe 8.

[0035] The mask 1 is provided with a plurality of vents 14, which can dissipate heat to the user's face to prevent the user's head from sweating when the part covered by the mask 1 is working for a long time.

[0036] An elastic pad 20 is provided on the top of the inner wall of the mask 1, and the elastic pad 20 is used to support the top of the head.

[0037] The inner wall of the mask 1 is connected to a support pad 17 for fitting the forehead of the user through multiple springs 18. An elastic belt 19 is provided on the mask 1. The elastic belt 19 is used to be fixed to the head of the user. The elastic belt 19 can expand and contract with the size of the user's head. The expansion and contraction of the elastic belt 19 in conjunction with the spring 18 can further improve the adaptability of the device to users with different head circumferences.

[0038] A battery 13 is provided on the mask 1, and a control panel 7 is provided on the front of the shell 6. The control panel 7 is provided at a position that is convenient for the user to operate.

[0039] With the above structure, the mask 1 is worn, the sealing ring 16 contacts the user's mouth and nose, and the outside air is sucked into the ventilation pipe 8 through the fan 9, but the air flow rate is not easy to be too fast. The outside air enters the shell 6 through the air vent 15 for the user to breathe, and the gas exhaled by the user can also be discharged through the ventilation pipe 8. This can avoid heavy moisture in the shell 6 and affect the user's comfort. When the user's oxygen intake increases, oxygen can be released into the shell 6 through the oxygen cylinder 12 to increase the oxygen content of the gas inhaled by the user. At the same time, the fan 9 is turned off to avoid the rapid discharge of oxygen through the ventilation pipe 8, resulting in waste.
