Technical Field

The invention relates to the technical field of sanitary protective articles, in particular to a filtering type protective neck sleeve.

Background

The neck cover is one of neckerchief, usually becomes a closed ring form, can directly embolia the neck, and the neck cover is worn on the neck and is difficult for falling, receives the favor of many consumers. The neck cover can be divided into sun-proof neck cover, heat preservation neck cover, motion neck cover, decoration neck cover etc. according to the function difference, it is the motion safeguard function to use, though it has to wear the use mode various, change the frequency low, characteristics such as body surface area of coverage is big, it does not have virus safeguard function, can't use as health safety protection apparatus, because the attack of influenza virus in recent years, various pneumonia, influenza abuse, health protection obtains the high importance of country and people, various virus protection gauze mask takes place in due charge, the protection gauze mask who uses at present has following several not enough: firstly, the aging is short, the replacement frequency of the common disposable flat protective mask is 4-8 hours, the replacement frequency of the KN95 protective mask is 2-3 days, the common people generally adopt the disposable flat protective mask with lower price in the daily protection, and the loss of each person is 2-3; secondly, the mask is not comfortable to wear for a long time, and people are required to wear the mask for a long time in a large epidemic situation, so that the face, auricles and the position of the nose bridge are easily damaged; third, can't accomplish face and the omnidirectional protection of neck, wear the in-process at long-time gauze mask, cause the body surface damage of person of wearing easily, virosome or germ body invade the human body through the body surface wound easily, cause the infection, if the person of wearing has the body surface wound of face or neck in addition, then wear the gauze mask and can't play omnidirectional virus protection effect to it. For example, chinese patent grant publication no: CN108135299B, entitled Notice date 2019 No. 11/19, the invention is named as disposable mask. In the disposable mask (10), the low rigidity area (14) is positioned at a position lower than a transverse central line (Q) which bisects the size of the mask main body (20) in the vertical direction (Y), the low rigidity area (14) extends along the width direction (X) and has a specified width in the vertical direction (Y), and the rigidity is lower than other parts, which has the disadvantages that the mask is short in time, the replacement is frequent, and the resource is wasted; the mask is not comfortable to wear for a long time, and people are required to wear the mask for a long time during a large epidemic situation, so that the face, auricles and the position of the nose bridge are easily damaged; can't accomplish face and the omnidirectional protection of neck, wear the in-process at long-time gauze mask, cause the person's of wearing body surface damage easily, virosome or germ body invade the human body through the body surface wound easily, cause the infection, if the person of wearing has the body surface wound of face or neck in addition, then wear the gauze mask and can't play omnidirectional virus protection effect to it. For another example, chinese patent application publication No.: CN203226291U entitled multifunctional neck cover No. 09/10/2013, the invention provides a multifunctional neck cover, which comprises a surrounding cover, wherein one end of the surrounding cover is provided with a rope and a rope locking buckle for adjusting the size of an opening, two ends of the rope are crossed with the rope locking buckle and pass through the rope locking buckle, the surface of the surrounding sleeve is provided with an elliptical hole, the long axis of the elliptical hole is parallel to the long axis of the opening ellipse of the surrounding sleeve, the elliptical hole is arranged at the center of the surface of the enclosing sleeve, the length of the long axis of the elliptical hole is less than or equal to the long axis of the opening ellipse of the enclosing sleeve, according to different requirements, the windproof neck guard can be used as a warm-keeping neck guard mask, a conjoined cap, a neck guard mask and a neckerchief, plays the roles of wind prevention and warm keeping, can be used for cold outdoor operation, the technical scheme has the defects that the cold-proof device can only be used for keeping the face and the neck warm, and cannot be used as a sanitary safety protection appliance when infectious diseases such as influenza and the like are attacked.

Disclosure of Invention

The invention provides a filtering type protective neck cover which is long in time effect, free from frequent replacement of a filtering base material, comfortable to wear, difficult to cause body surface damage and capable of comprehensively protecting the face and the neck and comprehensively protecting the face and the neck, and is used as a virus (anti-) resistant sanitary safety protective tool, aiming at solving the defects that a mask in the prior art is short in time effect, frequent in replacement, uncomfortable to wear and not easy to cause body surface damage when being worn for a long time, and a neck cover cannot be used as a virus (anti-) resistant sanitary safety protective tool when infectious diseases such as influenza come.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a filtration formula protection neck cover, includes the neck cover body of tube-shape and is used for the filtration substrate of virus protection, it arranges the inboard in the neck cover body to filter the substrate hoop. The filtering type protective neck sleeve provided by the technical scheme is composed of a neck sleeve body and a filtering base material which is annularly arranged on the inner side of the neck sleeve body, wherein the neck sleeve body is composed of one layer or multiple layers, the filtering base material is mainly composed of melt-blown non-woven fabrics which have the filtering efficiency of salt media of more than 95% and the filtering efficiency of oily media of more than 95%, the melt-blown non-woven fabrics can effectively filter and block more than 95% of non-oily particles with the particle size of (0.075 +/-0.020) mu m and oily particles with the particle size of (0.185 +/-0.020) mu m, the requirements of the technical specification of a daily protective mask can be met, and the filtering type protective neck sleeve has the effect of preventing (resisting) viruses; when the protective neck cover is worn and used, the lower eave of the neck cover body is sleeved into the neck, the upper eave of the neck cover body is hung at the nose bridge, if the upper eave is loose, an adjusting soft belt can be arranged inside the upper eave of the neck cover body, the adjusting soft belt is extruded to be tightly attached to the outer side of the nose bridge, the effect of fixing the upper eave of the neck cover body is achieved, the neck cover body is prevented from sliding downwards, and the protective neck cover is fixed by means of elasticity of the protective neck cover, so that a force point does not exist compared with an ear-hung mask, the protective neck cover is more comfortable to wear, the body surface damage is not easy to cause, and the use is more convenient and safer; in the protective neck sleeve after being worn, the filtering base material can cover the face and the neck in a full area, so that particles and virus and germs can be effectively blocked and filtered, the infection caused by the contact of the substances with the body surface can be prevented, and the all-round protection can be realized; because the coverage area of the effective part is large, the dust filtration and virus resistance (resistance) capabilities are long in duration and the service life is long, the filter base material does not need to be frequently replaced, and the resources and the cost are saved.
