Description

Haze mouth mask

Technical field

The utility model relates to a kind of protective device for respiration, more particularly, relates to a kind of haze mouth mask.

Background technology

Universal along with industrial expansion and private car, the pollution problem of urban air is more and more severe, especially PM2.5 content overproof, has a strong impact on the health of people's trip.Suck too much harmful substance to reduce, dressing mouth mask is a kind of common precautionary measures.

The most original mouth mask is medical formula integration mouth mask, cover body is made up of filterability nonwoven cloth material, and user relies on the filtration of this non-woven fabrics to mask the dust granules in outside air, this kind of mouth mask due to structure simple, with low cost, therefore obtain within the specific limits and use widely.But this kind of mouth mask also exists some defects: the resistance of air through mouth mask will be overcome when user breathes, therefore require that user must firmly breathe when using it and could suck enough air; Worse, the waste gas of exhalation is trapped in mouth mask mostly, so not only blocks entering of fresh air, and a small amount of fresh air is inhaled in lung again also to make waste gas a large amount of in mouth mask mix.The situation of this shortage fresh air can allow those comparatively weak users be sick in the stomach and discomfort, especially suffers from old man and the child of chronic respiratory disease.

In order to strengthen the air flow property inside and outside mouth mask, reduce the breathing difficulty of mouth mask user, people design a kind of gauze mask of fan attachment device on mouth mask, as Duo Chi bio tech ltd of Sichuan Province applied for on December 10th, 2014, publication number is CN104190014A, name is called the application for a patent for invention of " the cavate mouth mask with oxygen-supplying function ", disclose a kind of position corresponding with the mouth and nose of people inside mask body and fix gas grid box with mini-fan, this mini-fan is by the air intake of mouth mask outside, breather's snout is fed through after the nonwoven layer of mouth mask is filtered, reach and reduce the object that user breathes difficulty.But the mouth mask of this structure still exists a drawback: air is directly blowed to the snout of people by fan, this can cause very uncomfortable constriction to user, when the winter of cold, faces the cold wind blown like this directly and people will be made to be difficult to breathe.

People design again a kind of mouth mask with breather valve below, such as " cold flow (coolflow) " valve of the present 3M company that usage ratio is higher on the market.But this valve can only improve the comfort level that mouth mask uses a little, because it still needs certain respiratory intensity, could force this valve open in exhalation process.In addition, add in disposable breathing mask such valve by significantly increase mouth mask price, reduce its competitiveness in the market.

Also have various of the respiration auxiliary system of power supply air in the market, Versaflow and the Powerflow7900PF system of such as 3M company, but these systems are usually all very heavy, expensive and be not suitable for consumption market.The various forms of use electric fan that relates to is also illustrated to overcome the powered respirators of resistance when air flows through filter element in United States Patent (USP) 6854464,7464705 and 4233972.

In United States Patent (USP) 6257235, disclose a kind of mouth mask, described mouth mask adds a fan to improve its gas permeability and comfort level.But this invention has a lot of shortcoming, comprising: a. it need the mouth mask of particular design, this mouth mask devises an interface to guarantee that fan is fixed on mouth mask safely, and this is at present on the market not available for traditional mouth mask.Unless that is revise on a large scale disposable breathing mask conventional on the market at present, otherwise this invention will can not get effective application; And with regard to actual demand, its cost performance is also far below other disposable breathing mask.B. fan is positioned at the bottom of mouth mask, this means in the hot gas of characteristics of contaminated respiratory droplets, and those do not have immediately by the part that fan is extracted out, will rise and be trapped in the top of mouth mask air chamber.The damp and hot waste gas of c. breathing out directly blows to mouth mask, and moisture wherein and heat also remain on the filter medium of mouth mask, is again sucked together in final mixed fresh air after filtration.D. for ensureing certain comfort level, mouth mask is soft, and this may cause the face of fan distance user too near, thus enough space can not be provided to ensure that fan normally works.

Utility model content

The utility model object is to provide a kind of haze mouth mask, to solve the expiratory dyspnea that existing mouth mask on the market exists, poor for applicability, the various problem of high in cost of production.

For achieving the above object, technical solution adopted in the utility model is: a kind of haze mouth mask, comprise mask body and stitching and be fixed on breather valve in mask body, one-way type catch is provided with in described breather valve, breather valve top is provided with valve opening, on described breather valve, suit is fixed with Connection Block, described Connection Block top is provided with Connection Block exhaust outlet, described Connection Block top is fixedly connected with lid, and Connection Block exhaust outlet communicates with the pore be located in described lid, described lid internal fixtion has fan, described fan is electrically connected to battery and PCB assembly, air in described mask body is formed current path from the inside to the outside by described fan, and discharge from the lid exhaust outlet that described lid is offered.

The technical scheme realizing the utility model object also comprises further, described Connection Block inwall is provided with buckle and kinge-joint knot, the valve opening of described buckle and kinge-joint knot and described breather valve both sides is interlocked, described Connection Block suit is fixed on described breather valve outside, and the valve opening of described breather valve communicates with the Connection Block exhaust outlet at Connection Block top.

Further, described lid comprises the first lid be connected as a single entity, second lid, 3rd lid, pore is provided with between described first lid and the second lid, wire guide is provided with between described first lid and the 3rd lid, described Connection Block top is fixedly connected with the first lid, described second lid is provided with lid exhaust outlet, and at inner fan attachment seat, described fan base is provided with fan base exhaust outlet, and at inner fan attachment, and described lid exhaust outlet communicates with fan base exhaust outlet, described 3rd lid internal fixtion battery and PCB assembly, the wire of described fan is through pore, first lid and the wire guide between the first lid and the 3rd lid are connected to described battery and PCB assembly.

The beneficial effects of the utility model are:

1, the utility model adopts the frame mode reverse with the mouth mask of existing band blast type fan, be air-exhaust type by the fan design on mouth mask surface, the waste gas of mouth mask inside is discharged outwardly, negative pressure is formed in mouth mask inside, outside air flows into mouth mask inside after mouth mask filters, and accelerates the air circulation of mouth mask inside, makes people be able to comfortable breathing to ozone, be convenient to wearing of any colony, ensure the respiratory health of people;

2, the exhaust apparatus of the utility model front end can demolition and maintenance easily, and directly can be mounted on the mouth mask of existing band breather valve general on the market, therefore the utility model singly can not use in integrated marketing, the mouth mask that also only exhaust apparatus can be fixed on existing band breather valve uses, without the need to carrying out any structure change to existing mouth mask product, versatility is more extensive, reduces product promotion cost, has good economic and social benefit;
