Abstract
The utility model discloses a head-mounted air filter for breathing, which comprises a left filter cartridge, a right filter cartridge, air-guide tubes, a nasal mask and a compress band. The left filter cartridge and the right filter cartridge are respectively arranged on two sides of cheeks, and the lower ends of the left filter cartridge and the right filter cartridge are respectively communicated with the nasal mask through the air-guide tubes. Each filter cartridge comprises a cartridge cap and a cartridge body which are fastened to be an integral body, a filter element is clamped in the middle of each filter cartridge, and holes in a network structure for heavy breathing are distributed on the outer surface of the cartridge cap. The lower side of the cartridge body is provided with a connecting port to be connected with one of the air-guide tubes, the left filter cartridge and the right filter cartridge are connected through the compress band, and the air filter can be used by being fixed on the face of a user and placing the nasal mask on a nose of the user. The air filter has simple structure and flexible appearance design, and changes ugly appearance of an existing filter which covers a mouth and a nose integrally. The nose is covered for unidirectional inhaling, the mouth is used for exhaling, a check valve arranged on the existing filter is abandoned, and the air resistance in the inhaling process is reduced, thereby effectively avoiding harms of vehicle exhaust and flying dust in a construction site. The mouth of the user is outside the nasal mask, thereby being convenient to contact and communicate through a commonly-used communication tool and providing reliable guarantee for safe and coordinated construction.
Description
Technical field
The utility model discloses a kind of air cleaner, particularly a kind of wear-type breathing air filtration device.
Background technology
The trackman of power department usually is in the construction of highway avris, for preventing to be subjected to the harm of vehicle exhaust, automobile raising-dust, need wear the breathing air filtration device.Existing wear-type breathing air filtration device is the unified cover of people's mouth and nose, this cover is provided with two non-return valves, the logical filter cartridge in non-return valve front, it before the box atmosphere, this valve leads to when the people is air-breathing, and second non-return valve on the cover closed, and inhaled air is all through filtering like this; When exhaling, first non-return valve is closed, and second non-return valve opened, and the waste gas that the people breathes out directly enters atmosphere through second non-return valve.Such filter uses in line construction and is inconvenient.Moreover, the distance that the workmen of power circuit launches on construction surface usually is very long, keep the communication of head and the tail very necessary to guaranteeing safety and construction coordination, because existing wear-type breathing circuit filter is that staff's mouth and nose unification has been covered, the workmen uses communication tool to get in touch with and is restricted.
Summary of the invention
The utility model is in order to solve the problems referred to above that existing wear-type breathing circuit filter exists; the spy provides a kind of follow-on wear-type breathing air filtration device; its structure is simpler, easy to use; not only make the workmen in line construction, can prevent to be subjected to the harm of vehicle exhaust and airborne dust; and the communication in the convenient construction process, for the coordination of construction has taken into account the workers'health protection with providing safely when guaranteeing.
The utility model has adopted following technical scheme:
Two filter cartridges and wireway thereof about this wear-type breathing air filtration device comprises, and nose front shroud and deposited band with elastic force, about two identical cheek both sides that are arranged symmetrically in of filter cartridge function, its bottom side is communicated with described nose front shroud by described wireway respectively, about two filter cartridges all can connect described deposited band, help is fixed on people's face to air cleaner, and the nose front shroud covered on the nose uses.
Described filter cartridge comprises lid, crosses filter core and box body, and lid, box body fasten one, and core is filtered in middle clamping, and described lid outer surface is distributed with reticulated cell with logical atmosphere; Described box body lower side is provided with the wireway interface with the described wireway of convenient connection, and box body also is provided with the deposited band that connects described deposited band.
Described filter cartridge and lid all adopt hard plastic matter to make, and circle is highly lower, conveniently is affixed on the cheek both sides.
The composite fibre materials sheet that described filter core adopts high-tech strong to the contaminate particulate capture ability, that permeability is good to handle is overrided to form.
Described wireway adopts the flexible plastic material of good springiness to make.
Described nose front shroud can cover position, nose middle and lower part fully, and left and right sides respectively is provided with joint and connects wireway and then be communicated with filter cartridge.
The nose front shroud adopts the duroplasts material, and its edge is surrounded by that elasticity is soft moulds, and is beneficial to the applying to face.
This wear-type breathing air filtration device is simple in structure, and configuration design is flexible, has changed the ugly profile that existing filter mouth and nose are unified quilt cover.It covers nose, carries out one-way intake, exhales and is served as by the oral cavity, has abandoned the set non-return valve of existing filter, and the breathing process vapour lock reduces, and can effectively prevent the harm of job site vehicle exhaust and airborne dust; People's oral cavity is outside nose cup, and function is liberated, and conveniently carries out contact communication by communication tool commonly used, for safe construction provides reliable assurance with coordinating to construct.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of filter cartridge.
The specific embodiment
Introduce embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, this wear-type breathing air filtration device is mainly by filter cartridge 1, wireway 2, nose front shroud 3 with apply and be with 4 to form.
About two filter cartridges 1 be arranged in the cheek both sides, its lower end is communicated with nose front shroud 3 by wireway 2 respectively, about two filter cartridges 1 be with 4 to connect by having the deposited of elastic force, this breathing air filtration device can be worn the face that is fixed on the people on the head, and nose front shroud 3 covered on nose and the upper lip use.
Shown in Figure 2, filter cartridge 1 comprises lid 1a, box body 1c and mistake filter core 1b, and lid 1a, box body 1c fasten one, and core 1b is filtered in middle clamping, and lid 1a outer surface is distributed with reticulated cell with logical atmosphere; Box body 1c lower side is provided with wireway 2 interface 1e connecting wireway 2, and is provided with and connects the deposited band 1d that applies with 4.The lid 1a of filter cartridge 1, box body 1c all adopt hard plastic matter to make circle, are affixed on the cheek both sides during use; The composite fibre materials that filter core 1b adopts high-tech to handle is overrided to form, this filter core 1b material is very strong to the contaminate particulate capture ability, permeability is also relatively good, it is the matured product on the market, a plurality of kinds are arranged, and be easy to change and use, the air pollution situation of visual concrete workplace is determined before use.
Wireway 2 adopts the flexible plastic material, and its Cross section Design is a rectangle, and makes length-width ratio greater than 2, and such shape makes the good springiness of horizontal direction, is beneficial to the applying of filter cartridge 1 and cheek.
