[0041] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the utility model in a schematic manner. Although the illustrations only show components related to the utility model rather than being drawn according to the number, shape and size of components in actual implementation, the form, quantity, positional relationship and proportion of each component in actual implementation can be changed at will under the premise of realizing the technical solution of this party, and the component layout form may also be more complicated.

[0042] Example

[0043] This embodiment provides a welding protection device, such as Figure 1 As shown, it includes a mask 1 and a motor 2, and the mask 1 and the motor 2 are connected through an air duct 3.

[0044] like Figure 1As shown, the mask 1 is provided with a head-mounted ring 5 and a buckle 6. The operator wears the mask 1 on the face through the head-mounted ring 5, and then fixes the mask 1 to the face through the buckle 6. As an example, there are two buckles 6, and the two buckles 6 are symmetrically distributed on both sides of the mask 1; one end of the buckle 6 is fixed on the mask 1, and the other end is a movable end, and the movable ends of the two buckles 6 match, so that the two buckles 6 can be connected. In this embodiment, the length of the head-mounted ring 5 and the buckle 6 is adjustable. For example, the head-mounted ring 5 and the buckle 6 can be made of elastic material, or a length adjustment device can be provided on the head-mounted ring 5 and the buckle 6. The specific implementation is well known to those skilled in the art and is not limited here.

[0045] like Figure 1 As shown, a filter device 4 is installed on the mask 1 for filtering the air entering the mask 1 from the outside. As an example, the filter device 4 includes an activated carbon box 41, a second filter cotton 42 and a cover 43, wherein the activated carbon box 41 is connected to the mask 1, and the activated carbon box 41 contains activated carbon, which has strong adsorption and can adsorb manganese particles in manganese vapor; the second filter cotton 42 is located between the activated carbon box 41 and the cover 43, and the second filter cotton 42 can effectively filter out manganese particles in the air, thereby ensuring the cleanliness of the inhaled air; the cover 43 is used to fix the second filter cotton 42 on the activated carbon box 41. It should be noted that during the use of the welding protection device, the activated carbon box 41 and the second filter cotton 42 can be replaced in time as needed.

[0046] like Figure 1 As shown, the mask 1 is also provided with an air outlet 7. As an example, the air outlet 7 is located below the filter device 4, so that when the operator wears the mask 1, the position of the air outlet 7 corresponds to the operator's mouth, so that the operator's exhaled air can be discharged from the mask 1. In this embodiment, the air outlet 7 is a one-way air outlet, and the gas can only flow from the inside of the mask 1 to the outside through the air outlet 7, thereby preventing external gas from entering the inside of the mask 1 through the air outlet 7.

[0047] like Figure 1 As shown, the motor 2 is connected to the mask 1 through the air duct 3, and the motor 2 is used to deliver clean gas to the mask 1. In this embodiment, the air duct 3 is a corrugated air duct.

[0048] like Figure 1As shown, the motor 2 is provided with an air intake fan 21 and a filter slot 22, wherein the air intake fan 21 is located on the side of the motor 2; the filter slot 22 is located inside the motor 2 and is arranged in parallel with the air intake fan 21, and the filter slot 22 is used to place a first filter cotton (not shown in the figure). As an example, the number of the air intake fans 21 can be set according to actual needs. In the present embodiment, the number of the air intake fans 21 is two. In actual operation, the air intake fan 21 draws air from the environment into the motor 2. When it flows through the filter slot 22, the first filter cotton can filter out manganese particles in the air. The filtered air is delivered to the mask 1 by the air duct 3, thereby ensuring the cleanliness of the air inhaled by the operator. It should be noted that during the use of the welding protection device, the first filter cotton can be replaced in time as needed.

[0049] like Figure 1 As shown, a shoulder strap 8 is installed on the motor 2, so that the operator can carry the motor 2 on his back for portable operation. As an example, the two ends of the shoulder strap 8 are detachably connected to the motor 2 through a locking ring 80.

[0050] like Figure 1 As shown, the motor 2 is provided with a power switch 23 and a regulating switch 24 , wherein the power switch 23 is used to control the start and stop of the motor 2 , and the regulating switch 24 is used to adjust the air volume sucked in by the suction fan 21 .

[0051] like Figure 1 As shown, the motor 2 is provided with a fault indicator light 25 and a power indicator light 26 . The fault indicator light 25 is used to indicate that the motor 2 has a fault, and the power indicator light 26 is used to display the power of the motor 2 .

[0052] like Figure 1 As shown, a battery 9 is mounted on the motor 2, and the battery 9 is detachably connected to the motor 2. As an example, a charging socket 90 is provided on the battery 9, and the battery 9 can be charged through the charging socket 90 using a power cord (not shown in the figure).

[0053] The method of using the welding protection device provided in this embodiment is as follows:

[0054] First, before using the welding protection device, ensure that the device has sufficient power, which can be checked through the power indicator light 26; if the power is insufficient, plug the power cord into the charging socket 90 to charge the battery 9.

[0055] Next, check whether the filter device 4 is well connected to the mask 1, and whether the activated carbon box 41, the second filter cotton 42 and the cover 43 in the filter device 4 are well installed and pressed; in addition, place the first filter cotton in the filter slot 22 and check the installation, pressing and sealing conditions.

[0056] Next, the operator carries the motor 2 on his back and turns on the power switch 23 on the motor 2. The air intake fan 21 starts to deliver gas to the mask 1 through the air duct 3. At this time, the operator can put his hand inside the mask 1 to check whether there is gas flowing in.

[0057] Next, the operator presses the mask 1 against the face and covers the nose and chin, puts the headband ring 5 on the top of the head, tightens the buckles 6 on both sides of the mask 1, and buckles the buckles 6 behind the head to ensure that the mask 1 and the face are tightly sealed.

[0058] Next, the air volume delivered to the mask 1 is adjusted by adjusting the switch 24 . In addition, the gas exhaled by the operator during the welding process is discharged through the air outlet 7 at the lower part of the mask 1 .

[0059] Finally, the welding is completed, the power switch 23 is turned off, and the mask 1 and the strap 8 are removed.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
