Description

Technical Field

[0001] The utility model relates to the field of welding masks, in particular to a welding mask with high air permeability. Background Art

[0002] When the electric welder is working, the powerful arc it generates directly damages the worker's eyes, face, etc., so a mask is needed to protect them as much as possible. Existing mask materials are generally made of polypropylene, PE plastic, etc. This material has a good protective effect and is relatively light, but it also has poor air permeability. In order to improve its air permeability, some welding masks will be equipped with a fan inside the welding mask to improve the fluidity of the air inside, thereby achieving the purpose of improving air permeability and ensuring wearing comfort.

[0003] After searching, Chinese patent publication number: CN217744789U discloses a highly breathable welding mask, which relates to the technical field of welding masks. The utility model includes a mask body, a fastening strap fixed to one side of the mask body, an observation window fixed to one side of the mask body, and a plurality of brackets fixed to the upper surface of the mask body; a support cloth is fixed between the brackets, a protective shell is fixed to the top of the brackets, and a plurality of fixing blocks are fixed to the upper surface of the protective shell; the surface of the fixing block is provided with a mounting hole, and a threaded rod passes through the mounting hole. The utility model uses the protective shell to ensure that the user's head is breathable while protecting the user's head and preventing the hair from being entangled in the fan blades. At the same time, there is a certain distance between the protective shell and the connecting plate, which facilitates air circulation while ensuring the distance between the fan blades and the user's hair. At the same time, the motor is set to be detachable. When the weather is suitable and the fan blades are not needed, the motor can be removed to reduce the weight of the mask body.

[0004] In the above technology, a fan is installed on the top of the mask to accelerate the flow of air inside the mask, thereby improving the breathability of the mask. However, due to the certain weight of the fan and motor themselves, long-term use may also cause damage to the user's cervical spine. When heat dissipation is not needed, the fan needs to be removed, and this is done by rotating multiple sets of threaded barrels. The threaded barrels are located inside the top of the welding mask, which is troublesome to rotate and has low practicality. Therefore, a highly breathable welding mask is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3, an embodiment of the present invention provides: a highly breathable welding helmet, comprising a mask body 1, a filter is provided on the front side of the mask body 1, which can ensure that the user's eyes are protected when welding, and a strap is provided on the back side to ensure that the mask body 1 can be stably worn on the user's head, and a breathable barrier is also provided inside to prevent the fan blades from causing damage to the user. The filter, strap and breathable barrier are all existing technologies and can be implemented by technicians in this field. Since they are existing technologies, they will not be described in detail in this case. An adjustment mechanism is provided on the left surface of the top of the mask body 1, and a mounting mechanism is provided on the inner wall of the rear side of the top of the mask body 1. The mounting mechanism includes a supporting component 31, a fixing component 32, and a heat dissipation component 33. The supporting component 31 includes a cover plate 311, which contacts the inner wall of the rear side of the top of the mask body 1. A connecting plate 312 is fixedly connected to the front surface of the cover plate 311. When the cover plate 311 is opened and pulled out, the curved plate can be moved by the connecting plate 312 313 is brought out from the inside of the cover body 1 to ensure the linkage of the structural movement. The connecting plate 312 slides on the inner wall of the rear side of the top of the cover body 1. The front surface of the connecting plate 312 is fixedly connected with the arc plate 313. When the cover plate 311 is closed, the arc plate 313 is on the inner wall of the cover body 1, and the center of the circle is the same as the rotating rod 211. The inner wall of the arc plate 313 is slidably connected with the sliding bar 314. The outer walls of both ends of the sliding bar 314 are slidably connected with the arc plate 313 to ensure the cooling fan 331 The heat dissipation component 33 is arranged on the upper surface of the sliding bar 314. The outer wall of the right end of the sliding bar 314 and the inner wall of the curved plate 313 are interference fit, which ensures that the sliding bar 314 will not slide on the inner wall of the curved plate 313 under the action of external force. In addition, the weight of the heat dissipation component 33 cannot cause the sliding bar 314 to move, thereby ensuring its stability.

[0032] Reference Figure 2 - Figure 3The adjusting mechanism includes a rotating assembly 21 and a limiting assembly 22. The rotating assembly 21 includes a rotating rod 211 that ensures that the positioning frame 212 can rotate and can drive the cooling fan 331 to rotate stably. The rotating rod 211 is rotatably connected to the left surface of the top of the cover body 1. The right surface of the rotating rod 211 is fixedly connected with a positioning frame 212 for limiting the cooling fan 331. The limiting assembly 22 is set on the outer wall of the rotating rod 211. The limiting assembly 22 includes a ring 221. The ring 221 can only slide horizontally to the left or right on the outer wall of the rotating rod 211. The ring 221 is slidably connected to the outer wall of the rotating rod 211. The right surface of the movable rod 211 is fixedly connected with an insertion rod 222 for limiting the rotating rod 211. A groove 5 is provided on the left surface of the top of the cover body 1. There are multiple groups of grooves 5 to ensure that the rotating rod 211 can be limited by the insertion rod 222 when it is rotated to different angles. The right surface of the insertion rod 222 contacts the inner wall of the groove 5. The outer wall of the rotating rod 211 is sleeved with a spring 223. The spring 223 always pushes the ring 221 to move to the right through its own elasticity to ensure the stability of the insertion rod 222. One end of the spring 223 is fixedly connected to the left surface of the ring 221, and the other end of the spring 223 is fixedly connected to the right surface of the rotating rod 211.

[0033] Reference Figure 1 、 Figure 3 - Figure 4 The heat dissipation component 33 includes a fixed block 333, which is set to a trapezoidal shape and is adapted to the inner wall of the rear end of the heat dissipation fan 331 to ensure the stability of the heat dissipation fan 331 installed on its outer wall. The fixed block 333 is fixedly connected to the upper surface of the sliding bar 314, and the outer wall of the front end of the fixed block 333 slides with the heat dissipation fan 331. The heat dissipation fan 331 is a prior art, which can accelerate the fluidity of the air on the inner wall of the cover 1, thereby improving its air permeability, and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. As described above, a positioning groove 335 is provided at the front end of the cooling fan 331, and the positioning frame 212 contacts the inner wall of the positioning groove 335. A clamping groove 332 is provided on the inner wall of the rear end of the cooling fan 331, and a clamping block 334 is fixedly connected to the upper surface of the front end of the fixing block 333. The clamping block 334 is made of rubber material and has a certain elasticity to ensure that the clamping block 334 can be smoothly clamped on the inner wall of the clamping groove 332. At the same time, its upper surface is set to an arc surface to ensure that the clamping block 334 has a certain limit on the cooling fan 331, but will not jam it. The clamping block 334 contacts the inner wall of the clamping groove 332.

[0034] Reference Figure 2 - Figure 3When the cam 32 is in the unlocking state, the locking plate 322 is locked and the locking plate 323 is locked, so the cam 322 can be unlocked and locked.

[0035] Working principle: When the cooling fan 331 needs to be removed, the grip 321 can be rotated, and the grip 321 will drive the limit plate 322 to rotate and disengage from the inner wall of the limit slot 4. At the same time, the grip 321 will drive the torsion spring 323 to twist and deform. At this time, the grip 321 can be used to pull the cover plate 311 to move, so that the cover plate 311 drives the connecting plate 312, the curved plate 313, and the sliding bar 314 to move out from the inner wall of the top of the cover body 1. At this time, the cooling fan 331 and the fixing block 333 will move out together. Then, the cooling fan 331 can be pushed to separate it from the fixing block 333. When the cooling fan 331 is separated from the fixing block 333, the clamping block 334 will use its own elasticity to separate the curved surface from the inner wall of the clamping slot 332. When it needs to be installed later, the operating steps are the same as above, and the movement method between the structures is the same as above.

[0036] The spring 223 will push the ring 221 and the rod 222 to move in opposite directions through its own elasticity, so that the rod 222 is inserted into the inner wall of the groove 5, limiting the rotation rod 211 and improving practicality.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
