Abstract

The utility model discloses a head air filter which comprises left and right filtering boxes and an air guide pipe, a nose front cover and a packing belt, wherein the left and right filtering boxes are respectively arranged on the two sides of cheeks, the lower ends of the left and right filtering boxes are respectively communicated with the nose front cover through the air guide pipe, the filtering box comprises a box cover and a box body which are buckled into a whole, the middle of the filtering box clamps a filter element, and the external surface of the box cover is provided with a net-shaped hole so as to communicate with atmosphere; and the lower side of the box body is provided with an interface which is connected with the air guide pipe, the left and right filtering boxes are connected through the packing belt, and when in use, the air filter is fixed on a human face and the nose front cover covers a nose. The filter has the advantages that the structure is simple, the appearance design is flexible, and the ugly shape that the existing filter covers the mouth and the nose is changed. The head air filter only covers the nose, the one-way inspiration is performed, the expiration is performed by an oral cavity, a check valve adopted the existing filter is abandoned, the air resistance in an inspiration process is reduced, and the damage of automobile tail gas and dust at a construction site is effectively prevented; and the human oral cavity is out of the nose cover, and can conveniently carry out communication through a usual communication tool, and the head air filter provides reliable guaranty for safety construction and coordination construction.

Description

The wear-type air cleaner

Technical field

The utility model discloses a kind of air cleaner, particularly a kind of wear-type air cleaner.

Background technology

The trackman of power department usually is in the construction of highway avris, for preventing to receive 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 is atmosphere before the box, and this non-return valve is connected 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 of evolutionary operation is very long usually on construction surface for the workmen of power circuit; And keep the communication of head and the tail very necessary to guaranteeing safety and construction coordination; Because existing wear-type breathing circuit filter is to have covered staff's mouth and nose unification, 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 air cleaner; It is simple in structure, easy to use; Not only make the workmen in line construction, can prevent to receive the harm of vehicle exhaust and airborne dust, and the communication in the convenient construction process, the workers'health protection taken into account when giving security with safety for the coordination of construction.

The utility model has adopted following technical scheme:

Two filter cartridges and wireway thereof about this wear-type air cleaner 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 sides is communicated with said nose front shroud through said wireway respectively, about two filter cartridges all can connect said deposited band; Help is fixed on people's face to air cleaner, and the nose front shroud covered on the nose uses.

Said filter cartridge comprises lid, crosses filter core and box body, and lid, box body fasten one, and core is filtered in middle clamping, and said lid outer surface is distributed with reticulated cell with logical atmosphere; Said box body lower side is provided with the wireway interface with the said wireway of convenient connection, and box body also is provided with the deposited band that connects said deposited band.

Said filter cartridge and lid all adopt hard plastic matter to process, and circle is highly lower, conveniently is affixed on the cheek both sides.

Said filter core employing is strong to the contaminate particulate capture ability, the good composite fibre materials sheet of handling through high-tech of permeability is overrided to form.

Said wireway adopts the flexible plastic material of good springiness to process.

Said 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 air filter arrangement is simple, 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 able to liberation, conveniently carries out contact communication through communication tool commonly used, for safe construction and coordination construction provide reliable assurance.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation of filter cartridge.

The specific embodiment

Introduce the embodiment of the utility model below in conjunction with accompanying drawing:

As shown in Figure 1, this wear-type air cleaner 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 through wireway 2 respectively; About two filter cartridges 1 be with 4 to connect by having the deposited of elastic force, can this air cleaner 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 process 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, is the matured product on the market, and a plurality of kinds are arranged; And be easy to change and use, the air pollution situation of visual concrete workplace is confirmed 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.
