Abstract

The utility model relates to a mouthpiece with frame capable of changing filtering layer for health care and occupational safety. The utility model is characterized in that a filtering layer is clamped between an inner frame and an outer frame which are connected through a positioning rope belt, which are combined with the filtering layer to form an integral structure. The fine and thin elastic inner frame has the same structural shape as the outer frame, which are designed and formed according to the statistical type of the people's mouth and nose positions. The frames correspondingly are provided with rows of holes and four positioning holes, and the edge of the inner frame is provided with sealing strips. The utility model has the advantages of simple structure, changeable filtering layer, convenient ablution and broad application.

Description

Mouthpiece with frame capable of changing filtering layer

The utility model relates to a kind of health care and labor protection apparatus, particularly a kind of interchangeable filtering layer framework mouth mask.

Health gauze mask of the prior art mostly is multilayer gauze structure greatly, and its husky cloth filter fixed thickness is constant, can not regulate thickness of filter bed according to environmental condition and job requirement, and during use, mouth mask gauze face is close to people's nose and mouth, causes sense of discomfort easily; The cleaning treatment of mouth mask of getting dirty is loaded down with trivial details time-consuming, and poor performance is restored in regeneration.Other special protection mouth mask also exists complex structure, shortcoming that cost of manufacture is high, and its scope of application is restricted.

The purpose of this utility model is that a kind of simple in structure, interchangeable filtering layer framework mouth mask that thickness of filter bed is adjustable will be provided, it can improve the contact condition of mouth mask and human body effectively, help the cleaning of mouth mask and disinfect, and help reducing the mouth mask cost of manufacture.

The purpose of this utility model is achieved in that the replacing for ease of filtering layer, and filtering layer is clamped between inner frame and the outside framework; Adopt the location rope band to connect inner frame and outside framework, pulling location rope band can make inner frame, filtering layer and outside framework combination as a whole.The hole that several rows of correspondence is arranged respectively on inner frame and the outside framework, four corresponding locating holes are arranged respectively on four angles of inner frame and outside framework, the location rope band passes corresponding four locating holes and connects inner frame and outside framework, thin thin and whippy inner frame and outside framework are of similar shape, and the measurement type according to human nose and mouth designs, and inner frame is provided with the sealing edge strip near the edge of human body snout body one side.

The utility model so its structure is very simple, and is convenient to thickness of filter bed adjusting and filtering layer replacing because adopted the version of tank bracket clamping filtering layer; Simultaneously owing to adopted the frame structure shape that designs according to human mouth and nose measurement type, and band seals the inner frame of edge strip, so it can be suitable for all kinds of personnel's use.The utility model also has the advantage that cost of manufacture is cheap, clean convenient and applied range.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is interchangeable filtering layer framework Respirator structure schematic diagram;

Fig. 2 is interchangeable filtering layer framework mouth mask overall structure figure.

Among the figure: 1, outside framework, 2, the location rope band, 3, filtering layer, 4, inner frame, 5, the sealing edge strip, 7, hole, 8, locating hole.

During use, as required certain thickness filtering layer (3) is placed between outside framework (1) and inner frame they (4), the location rope band (2) that locating hole (8) is passed in pulling makes outside framework (1), and filtering layer (4) is combined as integral body.A side that seals the inner frame (4) of edge strip (5) with band is pressed close to the human body nose and mouth, because the effect of sealing edge strip (5), make the hole (7) of surrounding air on outside framework (1), on filtering layer (3), carry out filtration treatment, the hole (7) that passes again on the inner frame (4) enters the human body respiration organ, thereby reaches the protection purpose.Can do disposablely to make appliance and discard with the filtering layer of crossing (3).Inner frame (4) and outside framework (1) are carried out disinfection clean after, change the new filtering layer (3) of desired thickness, this mouth mask can reactivate.

Claims

1, a kind of interchangeable filtering layer framework mouth mask is made up of filtering layer and location rope band, and it is characterized in that: filtering layer (3) is clamped between inner frame (4) and the outside framework (1), so that the replacing of filtering layer (3); Location rope band (2) connects inner frame (4) and outside framework (1), and pulling location rope band (2) can make inner frame (4), filtering layer (3) and outside framework (1) combination as a whole.

2, interchangeable filtering layer framework mouth mask according to claim 1, it is characterized in that on inner frame (4) and the outside framework (1) several rows of corresponding hole (7) being arranged respectively, on (1) four jiao of inner frame (4) and the outside framework corresponding four locating holes (8) are arranged respectively, location rope band (2) passes corresponding four locating holes (8) and connects inner frame (4) and outside framework (1), thin thin and whippy inner frame (4) and outside framework (1) are of similar shape, and the measurement type according to human nose and mouth designs, and inner frame (4) is provided with edge sealing bar (5) near the edge of human body nose and mouth one side.
