Description

Ventilation filtering type anti-poison respirator

Technical field

The utility model relates to a kind of breathing and filters malicious device, especially a kind of ventilation filtering type anti-poison respirator.

Background technology

The present filtering type anti-poison respirator of the articles for labour protection that use is by mask main body, filter malicious box, outlet valve and frenulum and form; Mask main body is the flexible glue material, and the sealing ring of mouth mask and facial contact is to form with main body identical materials crimp, filters malicious box and just is fixed on the mask main body, and expiration valve seat and frenulum post are that duroplasts is made, and are not integrally formed; Mask main body is too soft when wearing can be out of shape, and makes sealing effectiveness not good, wears skin of face for a long time and has uncomfortable reaction, the poor safety performance of this in addition anti-poison respirator operation in closed containers such as groove, jar.

The utility model content

The purpose of this utility model is to provide a kind of ventilation filtering type anti-poison respirator, has comfortable wearing, good seal performance, advantage of wide range of application.

For achieving the above object by the following technical solutions

A kind of ventilation filtering type anti-poison respirator, form by mask main body, sealing ring, filter poison device, filter the inlet valve that malicious device directly connects mask main body, it is characterized in that: described mask main body is provided with inlet valve and outlet valve, on outlet valve, also be provided with the expiration bonnet, the inboard of mask main body also is provided with sealing ring, and described sealing ring is the air sac sealing circle of inflatable, and the bottom of air bag is provided with and adds air valve; The malicious device of described filter is made up of filter jug, filter malicious box and connecting plate, and filtering malicious device can be connected with inlet valve on the mask main body by a flexible pipe, also the malicious box of filtering in the malicious device of filter directly can be connected on the inlet valve of mask main body.

Described mask main body and outlet valve are integrated injection moldings.

There is a cell below of described expiration bonnet, is provided with water-absorbing sponge in the cell, then is provided with venthole on the wall of bonnet.

In the described filter jug filtered water is housed, Hu Kou is sealed and is provided with air inlet and gas outlet on pot lid by pot lid, air inlet is provided with an air inlet pipe, the lower end of air inlet pipe is immersed in the interior filtered fluid of filter jug, several apertures are also established in the lower end of air inlet pipe, the upper port of air inlet pipe is connected with the malicious box of filter, and the gas outlet is connected with flexible pipe.

This part surface that described air sac sealing circle contacts with skin of face is provided with protective layer of skin.

When the utility model uses, can adopt different combinations according to actual environment,, only need the filter poison box of the malicious device of filter is taken out separately if use in general following time of environment, be connected on the inlet valve of mask main body the usual quite at present filtering type anti-poison respirator that uses of the utility model this moment; When at groove; in the closed containers such as jar during operation; the content of oxygen is very low in the container; use general anti-poison respirator to exist very big potential safety hazard; the utility model couples together mask main body and the malicious device of filter with a flexible pipe; to filter malicious device during use is placed on outside the container; mouth mask is worn on the face; owing to adopted the air sac sealing circle; and the position that contacts with skin of face at the air sac sealing circle is provided with protective layer of skin; good seal performance not only; the comfort level of wearing is also relatively good; and breathing all is the air of process double medium filtration; the moisture content of breathing out from outlet valve is run into bonnet and can be condensed and flow in the cell of bonnet bottom, is absorbed by materials such as sponges, has avoided long working to have condensing water droplet and has fallen on the product and influence product quality.

Description of drawings

Fig. 1, structural representation of the present utility model;

The structural representation of Fig. 2, another embodiment of the present utility model.

The specific embodiment

As shown in Figure 1, 2, a kind of ventilation filtering type anti-poison respirator, form by mask main body 1, air sac sealing circle 2, the malicious device 3 of filter, on mask main body 1, be provided with inlet valve 11 and outlet valve 12, be provided with check valve 123 in outlet valve 12, also be provided with expiration bonnet 120 on the outlet valve 12, there is a cell 121 below of expiration bonnet 120, be provided with sponge 122 in the cell 121, the cap wall of expiration bonnet 120 is provided with several ventholes 124; In inlet valve 11, also be provided with check valve 123; Described mask main body 1 and outlet valve 12 are by integrated injection molding.

The inboard of mask main body 1 also is provided with the air sac sealing circle 2 of inflatable, and the bottom of air sac sealing circle 2 is provided with and adds air valve 130; The shape on the shape approximation human face surface after 2 inflations of air sac sealing circle.This that described air sac sealing circle 2 is contacting with skin of face partly is provided with protective layer of skin 20 on the surface.

Also be provided with several fixed legs on the mask main body, be used for installing and fixing frenulum.

The malicious device 3 of described filter is made up of filter jug 31, filter malicious box 32 and connecting plate 33, filters malicious device 3 and can pass through a flexible pipe 4 and be connected with inlet valve 11 on the mask main body 1.In the described filter jug 31 filtered water 310 is housed, Hu Kou is sealed and is provided with air inlet 312 and gas outlet 313 on pot lid by pot lid 311, air inlet 312 is provided with an air inlet pipe 314, during one end of air inlet pipe 314 extends to liquid in the filter jug 31 from air inlet 312 always, air inlet pipe 314 is immersed on the liquid tube wall partly and has several apertures 315, and the other end of air inlet pipe 314 is connected with the malicious box 32 of filter.

When at groove, in the closed containers such as jar during operation, the density of oxygen is very low in the container, use general anti-poison respirator to exist very big potential safety hazard, use the utility model mask main body 1 and the malicious device 3 of filter to be coupled together with a flexible pipe 4, to filter malicious device 3 during operation is placed under the good slightly environment of air quality, mask main body 1 is worn on the face, owing to adopted air sac sealing circle 2, the position that air sac sealing circle 2 contacts with skin of face is provided with protective layer of skin 20, good seal performance not only, the comfort level of wearing is also relatively good, and what breathe all is extraneous ozone, uses as safe as a house reliably; The moisture content of breathing out from outlet valve 12 is run into bonnet 120 and can be condensed into water droplet and flow in the cell of bonnet 120 bottoms 121, is absorbed by sponge 122, has condensing water droplet when having avoided long working and falls on the product, has influence on the quality of product; The utility model is filtered malicious device 3, adopt double medium filtration, extraneous air is malicious after filtration box 32 earlier, through active carbon filtration, advancing 314 from filter jug 31 air inlet pipe again goes into to filter jug 31 inner filtration water 310, enter into mask main body through the air after the two-layer filtration by flexible pipe 4 and sucked, harmful substance in the air and dust have all been filtered totally, can breathe fresh free of contamination air during operation through two-layer filtration by human body.

Another kind of embodiment of the present utility model is, the filter poison box 32 in the malicious device 3 of filter is taken out separately, is connected on the inlet valve 11 of mask main body 1, and this moment, the utility model just used as the usual filtering type anti-poison respirator that uses.
