All other embodiments obtained by a person of ordinary skill in the art based on the embodiments without making creative efforts shall fall within the protection scope.

Example 1

A breathable filter type epidemic prevention protective clothing is shown in figure 2 and comprises a protective clothing main body 1, a head cover 2 is arranged above the protective clothing main body 1, as shown in figure 3, ventilation filtering mechanisms 4 are arranged on two sides of the head cover 2, and an adsorption mechanism 5 is arranged on the front surface of the head cover 2.

As shown in fig. 4, the ventilation filter mechanism 4 includes: a vent 401; the inner wall of the ventilation opening 401 is fixedly connected with an air-permeable filtering frame 402, the inner wall of the air-permeable filtering frame 402 is fixedly connected with 2 or 3 or 4 or other installation rods 403 which are not communicated with each other in a designed quantity, and the central part of each installation rod 403 is provided with a fan 404; the fan 404 may be an electric fan or a hand fan, as desired. The air permeable filter frame 402 is fixed with a first spun-bonded layer 405, a melt-blown layer 406, an activated carbon layer 407 and a second spun-bonded layer 408 which are bonded with each other in sequence from the fan 404 to the human body on the inner wall between the fan 404 and the human body. The front surface of the head sleeve 2 is provided with goggles 3, the goggles 3 enable workers to normally visually observe the outside, and the front surface of the protective clothing main body 1 is provided with a zipper 6.

Through the technical scheme, the medical personnel firstly pull down the zipper 6 and pull up the zipper 6 after wearing the protective clothing. Then medical personnel start/manually rotate fan 404 when needing again, begin to provide the air towards headgear 2 is inside, and the virus that contains in the air is filtered in the setting of first spun-bonded layer 405 of rethread, melt-blown layer 406, activated carbon layer 407 and second spun-bonded layer 408, also can improve the inside air permeability of headgear 2, improves sufficient air for the wearer can be more comfortable. The melt-blown layer 406 is a multi-layer structure layer made of melt-blown nonwoven fabric, and has a filtering effect.

Compared with the prior art, the utility model discloses ventilative filtration formula epidemic prevention protective clothing has not only ensured the travelling comfort that medical personnel dressed, and adopts totally closed design, and in outside air only can filter back entering protective clothing through ventilation filter mechanism 4, had good airtight, medical personnel dressed the utility model discloses behind the protective clothing, with external air environmental control direct contact, showing and having reduced by the airborne virus, like the influence of new crown virus. Therefore, the utility model discloses protective clothing is in conventional service environment, like community work, nucleic acid check point, the medical care region of non-special requirement (if require to dress totally closed protective clothing's region, be suitable for the totally closed protective clothing that accords with the regulation requirement), is showing stronger than the medical protective clothing that relies on gauze mask, eye-shade, face guard to carry out facial protection to medical personnel's protective capacities now.

In the case of the example 2, the following examples are given,

based on embodiment 1 ventilative filtration epidemic prevention protective clothing, as shown in fig. 5, adsorption mechanism 5 includes installing port 501, one-way air outlet valve 502, stretching strap 503, adsorbed layer 504, the plug-in swing joint of installing port 501 inner wall has one-way air outlet valve 502, the outside fixedly connected with stretching strap 503 of one-way air outlet valve 502, the inner wall bonding of one-way air outlet valve 502 has adsorbed layer 504.

The outside of the one-way air outlet valve 502 is provided with a sealing ring 505, and the inner wall of the mounting port 501 is provided with a rubber sealing layer 506. The seal ring 505 and the rubber seal layer 506 form a stable fixed connection relationship based on elastic friction force, and an airtight state can be formed between the seal ring 505 and the rubber seal layer 506. The sealing ring 505 and the rubber sealing layer 506 can be made of elastic materials containing silver ions and having sterilization capacity according to requirements.

The one-way outlet valve 502 comprises: a hard breather hole plate 5023 which plays an isolation role is arranged between the inner side wall of the melt-blown cloth filter layer 5022 and the adsorption layer 504; a plurality of air vents are arranged on the hard air vent plate 5023 in a matrix manner; the outer side wall of the meltblown fabric filter layer 5022 is connected with a one-way exhaust valve 5021, and the one-way exhaust valve 5021 exhausts air to the outside of the head sleeve 2 in a one-way mode. Wherein, the melt-blown fabric filter layer 5022 is a multilayer structure formed by overlapping melt-blown non-woven fabrics. The rigid vent plate 5023 is made of plastic and has a plate structure with a plurality of through holes communicating with the adsorption layer 504 and the melt-blown cloth filter layer 5022. The one-way exhaust valve 5021 is a one-way exhaust valve with a diameter of 20-100mm in the Chinese Symphonic city.

Through above-mentioned technical scheme, medical personnel's during operation inspiratory air mainly is filtered air in the headgear 2 is gone into for ventilation filter mechanism 4 drum, and medical personnel's expired steam can discharge through one-way air outlet valve 502, and adsorbed layer 504 adsorbs steam this moment, prevents that headgear 2 from causing goggles 3 fuzzy because of steam in the steam. Generally speaking, the filter efficiency of the one-way air outlet valve with filtering action will be higher than the medical gauze mask of N95, the utility model discloses still installed the adsorbed layer 504 additional for steam can be preferentially adsorbed by the adsorbed layer 504, avoids steam to adsorb in the melt-blown fabric filter layer 5022 of one-way air outlet valve 502, causes the filtration pore of melt-blown fabric filter layer 5022 to be caused by the steam shutoff to breathe smoothly and the filter effect descends. Due to the arrangement of the hard ventilating orifice plate 5023, the adsorption layer 504 which adsorbs water vapor and the melt-blown cloth filter layer 5022 are prevented from being directly released, so that the melt-blown cloth filter layer 5022 is wetted.

After medical personnel dressed one section time, adsorbed a large amount of moisture of adsorbed by adsorbed layer 504 can cause inefficacy, and goggles 3 can be fuzzy because of the sweat steam of accumulation in the headgear 2 this moment, melts and spouts cloth filter layer 5022 and also can appear the steam adsorption problem of certain degree. Replacement of the adsorbent layer 504 and the meltblown filter layer 5022 is therefore required. At this time, medical staff can perform sterilization treatment on the outside of the protective suit through external sterilization equipment, and pull out the one-way air outlet valve 502 and the adsorption layer 504 integrally in a safety zone through manually pulling the pull belt 503. At this moment, medical personnel can replace a one-way air outlet valve 502 with a new adsorption layer 504 and a meltblown fabric filter layer 5022 to be inserted back into the mounting opening 501 after drinking water and eating in a safe area as required, so that the adsorption layer 504 and the meltblown fabric filter layer 5022 can be conveniently replaced.

Example 3
