Description

Technical Field

[0001] This utility model relates to the field of breathing mask technology, and in particular to a dual-inlet breathing mask with sound transmission function. Background Technology

[0002] Dust pollution is a common problem in modern industrial production, such as mining, cement manufacturing, and metal processing. Long-term exposure to high concentrations of dust can easily lead to occupational diseases like pneumoconiosis and respiratory inflammation, seriously threatening workers' health. Respiratory masks, as key equipment for dust protection, effectively block dust particles from entering the human respiratory tract through various methods, including physical interception, electrostatic adsorption, and filter media retention.

[0003] Currently, dustproof technology for breathing masks is relatively mature, and dustproof effects are continuously improved through optimizing the mask's sealing structure and enhancing the performance of filter materials. However, in actual industrial production scenarios, due to factors such as equipment operation and machinery handling, the ambient noise level often reaches 80 decibels or even exceeds 100 decibels. In such noisy environments, traditional breathing masks focus solely on dustproof functionality and lack effective sound transmission structure design. When workers wear them, sound transmission is obstructed, the mask's seal causes sound attenuation, and combined with ambient noise interference, daily work communication becomes extremely difficult. This not only affects work efficiency but may also lead to safety hazards due to poor communication. Utility Model Content

The receiving plate 62 is L-shaped, and two rows of protrusions 621 are symmetrically arranged on its lower surface. The end of the snap-fit ​​plate 63 is provided with a row of protrusions 631. The protrusions 621 and 631 increase the contact area with the connection band 71, preventing the connection band 71 from sliding and affecting its use.

[0026] The fixing component 7 includes two connecting straps 71 that pass through the snap-fit ​​component 6. One end of each connecting strap 71 is connected to both ends of the head frame 72, and the other end of each connecting strap 71 is provided with a buckle 73 and a collar 74, respectively. The connecting straps 71 are connected to the head frame 72, buckle 73, and collar 74 through a fastening plate 75. The fastening plate 75 has an opening, and a pressure plate 76 is provided in the opening. One end of the pressure plate 76 is fixedly connected to the fastening plate 75, and the other end is the pressing end. The connecting straps 71 are fixed by the pressing action of the pressure plate 76. When adjusting the length of the connecting straps 71, simply buckle the pressure plate 76 upwards to allow the connecting straps 71 to pass through the opening, adjust to the appropriate length, and then lower the pressure plate 76.

[0027] The fastening plate 75 is fixedly connected to the buckle plate 73 and the collar 74. The fastening plate 75 is connected to the head frame 72 through the connecting ring 751, the fixing post 752 and the clamping rod 753. The clamping rod 753 and the fixing post 752 are both fixedly connected to the end of the head frame 72, and the clamping rod 753 is located outside the fixing post 752. The connecting ring 751 is fixed to the end of the fastening plate 75. The connecting ring 751 is sleeved and connected to the clamping rod 753 and the fixing post 752.

[0028] In practical use, the breathing mask is placed over the user's face, the headband 72 is placed behind the user's head, and the buckle 73 and loop 74 are then connected around the back of the neck. After connection, the length of the connecting strap 71 on both sides is adjusted according to the actual situation to improve user comfort and ensure that the breathing mask fits the user's face. When inhaling, the air filtered by the filter enters the breathing mask through the air inlets 21 on both sides. At this time, the air inlet valve 24 moves inward. When exhaling, the air is exhaled through the air outlet 42. At this time, the air outlet valve 44 moves outward, and the air is discharged through the opening at the bottom of the protective cover 3. When communication is required, the user's voice is transmitted through the second sound transmission plate 55, the dustproof plate 54, the first sound transmission plate 53, and the sound transmission hole 33, which does not affect communication while preventing dust from entering.

[0029] Therefore, this utility model adopts the above-mentioned dual-inlet breathing mask with sound transmission function. By setting symmetrical air intake components, the cross-sectional area of ​​gas flow is increased, the air pressure inside and outside the mask is balanced, and the wearing comfort is improved. By setting sound transmission components, workers can talk directly without removing the mask, saving the tedious process of repeatedly removing and putting on the mask. At the same time, the sound transmission components and the mask body adopt an integrated design, which does not damage the sealing performance and improves the protection.
