Description

Technical Field

[0001] The present invention relates to the technical field of facial masks, and particularly to a mask that can prevent and control haze and actively disinfect bacteria and viruses. Background Art

[0002] Masks have been used for about seven or eight centuries in the application of protecting human life and health and preventing the spread of pollution, bacteria, and viruses. It is an important, commonly used, and indispensable protective tool for preventing pollution or the invasion of bacteria and viruses and protecting human life and health. It plays an important role in advancing with humans in the prevention and control of pollution, bacteria, and viruses, and protecting life, reproduction, and healthy growth.

[0003] In view of the inherent nature of the pollutants and pathogens targeted by masks, which often exist in the form of micronized haze or biochemical bacteria and viruses and cause pollution, infection, and spread, the early invention and application of masks mainly relied on the physical isolation, adsorption, and filtration and ventilation principles between mask layers to inhibit and block haze, bacteria, and viruses from entering the human respiratory tract and causing diseases, injuries, or the spread of infections to catastrophic consequences of major epidemics, thereby achieving the purpose of preventing and protecting humans and greatly reducing the occurrence and development of pollution, bacteria, or virus infections and the invasion and harm to life and epidemics. Haze pollutants, bacteria, and viruses, including pollutant-like substances or mutated bacteria and viruses, always coexist with the ecological environment of human existence and development. Therefore, in the process of its history and real life, masks have become an important and essential convenient protective tool that must be used in daily life at home, during travel, in the medical profession, or in disease control work.

[0004] Therefore, in modern times, in response to the need for protection, humans have successively had disposable masks to choose from, as well as masks such as N95 (American standard), KN95 (Chinese standard), and 3M with optimized performance. Subsequently, spray atomization disinfection and prevention and control medical devices have also been invented. Their principle and efficacy are to spray disinfectant and bactericidal liquid in the oral cavity, nasal cavity, pharynx, and larynx to inhibit or disinfect bacteria and viruses entering from the respiratory tract, nasal cavity, pharynx, and larynx, so as to achieve the purpose of preventing and protecting the human body from diseases. However, due to the inconvenience of carrying and using this product and its large limitations in storage and preservation, mainly because it is more suitable for use in relatively fixed environments such as homes and hospitals. Therefore, in outdoor public places, densely populated areas, or outdoor production and operation industrial and mining sites, the significant superiority of masks in terms of convenient prevention and protection is still continuously favored, improved, and preferred and temporarily irreplaceable. Especially in the sudden ecological environment of major pollution sources and bacteria and viruses, masks are more suitable for the public to use conveniently for protection. Moreover, for masks with high cost performance and better required efficacy and environmental protection and high quality, they are even more eagerly awaited by society but difficult to obtain. At the same time, it can also be extended to an air purifier to meet the disease control and protection needs in special environments.

[0005] The functional characteristics of the masks for preventing and controlling smog, bacteria and viruses commonly used in daily life are mainly passive isolation, adsorption and filtration for ventilation, but they cannot actively eliminate and kill the bacteria and viruses adsorbed on the masks. As a result, the wearers of the masks or the discarded masks become mobile or secondary pollution sources, spreading bacteria and viruses, which is an urgent problem to be solved in disease control and environmental protection.

[0006] There are still many deficiencies in the currently disclosed patent documents. For example:

[0007] (1) CN201620417626.7 discloses an ultraviolet disinfection and sterilization mask, which includes a mask body. A headband is connected to the mask body. At least one ultraviolet light generating device is arranged on the mask body. A power module is arranged on the headband, and the power module is electrically connected to the ultraviolet light generating device through a wire inside the headband. However, this ultraviolet disinfection and sterilization mask only uses ultraviolet light to disinfect and sterilize the mask, with a single function and unable to completely eliminate and kill various types of bacteria and viruses adsorbed on the mask.

[0008] (2) CN201820351049.5 discloses an infection prevention mask. A condensation breathing valve is arranged on the surface of the mask body. An ultraviolet disinfection lamp is arranged above the inside of the condensation breathing valve, and a control switch is arranged outside the condensation breathing valve. Similarly, this ultraviolet disinfection and sterilization mask only uses ultraviolet light to disinfect and sterilize the mask, with a single function and unable to completely eliminate and kill various types of bacteria and viruses adsorbed on the mask. In addition, directly arranging devices such as a storage battery in the condensation breathing valve on the surface of the mask body results in an overly large and heavy surface of the mask body, reducing the comfort of the wearer.

[0009] (3) CN201621081795.4 discloses a mask. By arranging a high-voltage electrostatic air purification device inside the mask and an air extractor at the bottom of the mask to extract the air inside the mask, and then arranging air inlets on both sides of the mask respectively, the air inlets are connected to the high-voltage electrostatic air purification device, and the outside air enters the mask after being filtered by the high-voltage electrostatic air purification device driven by the power of the air extractor. Although the principle of this high-voltage electrostatic air purification device is simple, it is actually difficult to implement, and it only uses high-voltage static electricity to disinfect and sterilize the mask, unable to completely eliminate and kill various types of bacteria and viruses adsorbed on the mask. In addition, directly arranging the air extractor on the mask body will also cause the surface of the mask body to be overly large and heavy, reducing the comfort of the wearer, which is not reasonable enough.

[0010] Therefore, it is imperative to inherit the classics and innovate and improve the application of new environmental protection functions of masks. Based on the fact that traditional masks have a single function, low structural resource utilization rate, insufficient or missing application of new technologies and new processes, as well as the needs of social environmental protection and disease control. Thus, it leads to new demands for social innovation-driven rich mask functions: it is inevitable to open up a new situation in the research and development and application of high-end masks, improve and meet the new choices of differentiated mask functions, and popularize the new functional masks with the concept of prevention and control, environmental protection and health.

[0018] Furthermore, the multifunctional mask body is provided with a first pressure-sensitive touch point switch for detecting the redundant function layer.
