Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment for glass processing and production, in particular to a breathing mask. Background Art

[0002] Respiratory masks are a common type of protective equipment that can filter and protect the air that enters the body when the user breathes. They are very common and are very common in some construction or processing industries. For example, in some glass processing industries, a large amount of dust will be generated when cutting or polishing glass. Therefore, in order to ensure the health of the workers and reduce the inhalation of dust into the body, a respiratory mask is needed to assist in production work.

[0003] However, most of the traditional glass processing auxiliary breathing masks lack a stable protective structure on the mask surface. Since the workers need to wear the masks for a long time for processing and production, the masks are in contact with the facial skin for a long time. As the pressure of wearing is applied, indentations will be produced on the face. As time goes by and the friction between the mask and the face increases, the facial surface skin will be squeezed and damaged by friction, which will cause great discomfort to the workers when wearing the masks. In addition, most of the traditional breathing masks lack a stable connection structure for the fixing belt structure. Most of them are single and independent fixing belt structures. During processing and production, the masks are often touched by the workers' body movements. Such single fixing belts often lack a stable limiting connection structure and are prone to slippage, thus affecting the stability of the mask. Utility Model Content

When the mask is worn for a long time, the extrusion damage caused by the contact position between the mask and the face can be reduced, which can provide a safe protective effect on the skin. The protective mask body 1 is respectively provided with a breathing filter valve 2 and an eye mask 3. The breathing filter valve 2 is a breathable structure, and a filtering structure such as a filter net is usually arranged inside the breathing filter valve 2, which can filter the breathable air. In this way, when cutting or grinding and polishing glass, it can effectively prevent dust from causing damage to the body of the worker, and play a stable protective role. This is a commonly used structure in a conventional mask breathing valve, which belongs to a mature prior art structure. A detailed description is not given here. The eye mask 3 can play the role of eye protection. The protective mask body 1 is fixedly connected with fixing belts 4 on both sides. The two fixing belts 4 are respectively provided with connecting blocks 1 5 and connecting blocks 2 6. A first connecting mechanism is provided between the connecting blocks 1 5 and the connecting blocks 2 6. The first connecting mechanism can enable the two connecting blocks to be stably docked together, so that the two fixing belts 1 4 are connected together, which can facilitate the mask to be worn and fixed on the face. The fixing belt 1 4 is located at the back of the head to achieve stable fixing of the mask. A positioning block 16 is provided on the top of the protective mask body 1, and a fixing belt 2 17 is fixedly connected to the positioning block 16.

During installation, the two mounting blocks 21 are correspondingly installed in the two mounting grooves 27, and the inclined surfaces on the limiting blocks 26 will be squeezed to the inner wall openings of the mounting grooves 27. Through squeezing, the inclined surfaces will play a guiding effect, so that the limiting blocks 26 slide and shrink and push the movable blocks 23 to compress the springs 24. When the two mounting blocks 21 are correspondingly inserted into the mounting grooves 27, the springs 24 are reset to push the movable blocks 23 to drive the limiting blocks 26 to be inserted into the limiting grooves 28, and the docking and installation of the second positioning connecting mechanism can be completed.
