Description
Technical Field
The invention relates to the technical field of face masks, in particular to a mask capable of preventing and controlling haze and actively eliminating and killing bacteria and viruses.
Background
The mask is used for protecting the life health of human beings, preventing and controlling the infection and the diffusion of the polluted bacteria and viruses for about seven-eight centuries. It is an important, common, indispensable protective tool to prevent contamination or bacterial viruses from invading humans and to protect human life health. It plays an important role in preventing and controlling the bacteria and viruses, protecting the life from reproduction and healthy growth.
Aiming at the characteristic that the mask prevents and controls the pollutants of the object and the disease origin and is usually in the form of micro haze or biochemical bacteria and virus, and generates the functions of pollution or infection, diffusion and invasion. Accordingly, the invention of the early mask is mainly applied to inhibiting and blocking haze and bacteria and viruses from entering human respiratory tracts to cause human diseases by the principles of physical isolation adsorption and filtration ventilation between mask layers, so that disastrous consequences of damage or infection and diffusion to major epidemic situations occur, and the purpose of preventing, controlling and protecting human beings from greatly reducing occurrence and development of harmful pollutants or bacteria and viruses from infection, diffusion and invasion to harm life epidemic situations is achieved. The haze pollutants and the bacterial viruses including the similar pollutants or the variant bacterial viruses are always generated along with the existence and development of ecological environments such as images and the like of human beings. Therefore, the mask is applied to the history and real life process, and is an important and main convenient protective appliance which is necessary, necessary and necessary in daily household, life and travel, medical care and occupational or disease control work.
Therefore, in recent times, in order to meet the protection requirements, people have successively selected disposable masks and masks with optimized and improved performance, such as American standard N95, national standard KN95, 3M and the like. Thereafter, a spray atomization type disinfecting, preventing and controlling medical appliance is also invented. The principle and the effect are that the sterilizing liquid is atomized at the oral cavity, the nasopharynx and the larynx so as to inhibit or kill the bacteria and viruses entering from the respiratory tract, the nasopharynx and the larynx, and the aim of preventing, controlling and protecting human bodies from diseases is fulfilled. But the article is inconvenient to carry and use and has large storage and storage limitations, and the article is mainly characterized by being more suitable for being used in relatively fixed environments such as home hospitals and the like. Therefore, in outdoor public places, areas with dense population flows or outdoor production operation industrial and mining places, the mask has the remarkable advantages of continuous advocation, improvement, first choice and temporary replacement of prevention, control and protection and convenient use. Particularly, in a great pollution source and a sudden ecological environment of bacteria and viruses, the mask is more suitable for the public to use in a convenient and fast protection way. Even if new coronavirus pneumonia is abused suddenly in spring of 2020 in the present century, the common mask is rare and valuable, and one mask is difficult to obtain. In addition, the environment-friendly mask with high performance-price ratio and better effect is required, and is especially difficult to buy as the society expects. Simultaneously the extension of doing satisfies disease control protection demand under the special environment for air purifier.
The functional characteristics of the daily-used mask for preventing and controlling haze and bacteria and viruses mainly only have the main functions of passive isolation adsorption and filtration ventilation, but can not actively kill the bacteria and viruses adsorbed on the mask, so that a wearer or a waste mask becomes a source of movement or secondary pollution, infection and diffusion of bacteria and viruses, and the worries of disease control and environmental protection to be solved urgently are considered.
The patent literature disclosed so far has many disadvantages, such as:
(1) CN201620417626.7 discloses an ultraviolet disinfection and sterilization mask, which comprises a mask main body, wherein a head-wearing rope is connected to the mask main body, at least one ultraviolet light generating device is arranged on the mask main body, a power supply module is arranged on the head-wearing rope, and the power supply module is electrically connected with the ultraviolet light generating device through a wire positioned inside the head-wearing rope. However, the ultraviolet disinfection mask only utilizes ultraviolet light to disinfect the mask, has a single function, and cannot completely kill various types of bacteria and viruses adsorbed on the mask.
(2) CN201820351049.5 discloses a prevention infection gauze mask, and gauze mask body surface is provided with the condensation breather valve, and the inside top of condensation breather valve is provided with the ultraviolet ray disinfection lamp, and the condensation breather valve outside is provided with control switch. Similarly, the ultraviolet disinfection and sterilization mask only utilizes ultraviolet light to disinfect and sterilize the mask, has single function, and cannot completely kill various types of bacteria and viruses adsorbed on the mask. In addition, with the direct setting of devices such as battery in the condensation breather valve on gauze mask body surface, lead to gauze mask body surface too big, overweight, reduce wearer's comfort.
(3) CN201621081795.4 discloses a mask, wherein a high voltage electrostatic air purification device is arranged in the mask, an exhaust fan is arranged at the bottom of the mask to extract air in the mask, air inlets are respectively arranged at two sides of the mask, the air inlets are connected with the high voltage electrostatic air purification device, and outside air enters the high voltage electrostatic air purification device from the air inlets under the driving of the exhaust fan, and is filtered and processed in the mask. Although the principle of the high-voltage electrostatic air purification device is simple, the high-voltage electrostatic air purification device is difficult to realize in practice, and various types of bacteria and viruses adsorbed on the mask cannot be completely sterilized only by using high-voltage static electricity to sterilize the mask. In addition, the exhaust fan is directly arranged on the mask body, so that the surface of the mask body is too large and too heavy, the comfort of a wearer is reduced, and the mask body is not reasonable enough.
Therefore, the novel environmental protection function application of the mask which is classically inherited, innovative and perfect is imperative. Based on the single function of the traditional mask, the low utilization rate of structural resources, the insufficient or missing application of new technology and the requirement of social environmental protection and disease control. Therefore, the new requirements of enriching the functions of the mask are driven by social innovation: the new situation of research and development and application of the high-end mask is opened, the new selection of the application mask function differentiation is perfected and met, and the new functional mask with the prevention, control, environmental protection and health idea is inevitably popularized and popularized.
