Description

Technical Field

[0001] The utility model relates to a healthy dust-proof mask, in particular to a novel healthy dust-proof mask with a filtering structure for workers. Background Art

[0002] In industrial production, construction and other environments, workers are often exposed to the threat of air pollutants such as dust and powder. Long-term inhalation of these pollutants is extremely harmful to the respiratory health of workers, may cause various respiratory diseases, and even threaten the safety of workers' lives. Therefore, it is very important to provide workers with effective respiratory protection equipment.

[0003] Although traditional dust masks can provide protection for workers to a certain extent, they still have many shortcomings. Among them, the inconvenience of replacing the filter is a prominent problem. When the filter is saturated or damaged, it needs to be replaced in time to ensure the dustproof effect. However, the filter replacement process of traditional masks is often cumbersome and complicated, which not only affects work efficiency, but also may cause the dustproof performance to decline due to improper replacement.

[0004] In addition, the fit of traditional dust masks is also an issue that needs to be improved. Since everyone's face shape and size are different, traditional masks often cannot perfectly fit everyone's facial contours. This not only reduces the wearing comfort, but also may cause dust to penetrate through the gaps, thus affecting the dust-proof effect.

[0005] Finally, traditional dust masks lack adaptability to different facial shapes. Workers’ facial shapes vary greatly, and the design of traditional masks is often relatively fixed and cannot be flexibly adjusted to meet the needs of different workers. This further limits the scope of application and protective effect of dust masks.

[0006] In order to solve these problems, we proposed a new healthy dust mask technical solution with a filtering structure. Utility Model Content

[0013] A face-contact strip body is arranged on the outer wall of the other side of the annular hollow elastic tube, and the outer edge of the face-contact strip body is fixedly connected to the outer wall of the annular hollow elastic tube.

[0014] As an improvement, the cross section of the embedding strip is U-shaped.

[0041] In conjunction with the accompanying drawings, a novel healthy dust mask with a filtering structure for workers includes a dust mask body 101;

[0042] The front part of the dust mask body 101 is provided with a filter insertion port 102, and the opening direction of the filter insertion port 102 faces upward; the filter insertion port 102 is provided with a filter tube body 301, and the filter tube body 301 is provided with a multi-layer dust filter body 302, and the upper edge of the filter tube body 301 is provided with a limit button 303; the two sides of the opening of the filter insertion port 102 are symmetrically provided with friction rubber sheets 103, and the inner side of the limit button 303 is closely attached to the friction rubber sheet 103, which plays a role of limiting; the user pushes the limit button 303 upward to realize the detachment of the filter tube body 301 from the filter insertion port 102, so as to facilitate the replacement of the filter tube body 301.

[0043] An outer face contact mechanism 200 is provided at the outer edge of the dust mask body 101; the outer face contact mechanism 200 comprises an annular hollow elastic tube 201, an outer wall of the annular hollow elastic tube 201 is provided with an embedding strip 202 with a U-shaped cross section, the back of the embedding strip 202 is fixedly connected to the outer wall of the annular hollow elastic tube 201, and the embedding strip 202 wraps the outer edge of the dust mask body 101; the outer wall of the other side of the annular hollow elastic tube 201 is provided with a face-tightening strip body 203 with a V-shaped cross section, and the outer edge of the face-tightening strip body 203 is fixedly connected to the outer wall of the annular hollow elastic tube 201;

[0044] The annular hollow elastic tube 201 is provided with an air filling and discharging valve 204;

[0045] The two sides of the dust mask body 101 are provided with head restraint belt bodies 401;

[0046] The two ends of the head restraining belt body 401 are respectively fixedly matched with the two sides of the dust mask body 101.

[0047] The material of the dust mask body 101 is plastic.

[0048] The material of the annular hollow elastic tube 201 is elastic rubber, and the inflation and deflation valve 204 and the annular hollow elastic tube 201 are tightly matched.

[0049] The embedding strip 202 is made of rubber, and the embedding strip 202 and the annular hollow elastic tube 201 are fixedly matched by bonding.

[0050] The material of the face-adhering strip 203 is latex;

This personalized adjustment function improves the comfort and sealing of the mask, and further protects the safety of workers.

[0068] Superior fit and comfort: The clever combination of the face-fitting strip 203 and the annular hollow elastic tube 201 enables the mask to better fit the facial contour when worn by workers, which not only improves the wearing comfort, but also effectively prevents dust from entering through the gaps, providing more comprehensive protection for workers.

[0069] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
