Abstract
The utility model discloses a breathing filter. This breathing filter supports the cover including a nasal surface and supports the flexible joint spare that the cover joint used with being used for with the nasal surface on the gauze mask, is equipped with a filtration supporting spring in the below that the nasal surface supported the cover, the left and right both sides limit and the outside limit of filtration supporting spring contact with the base that the nasal surface supported the cover, inlay on filtering the supporting spring and are equipped with two and human nasal cavity matched with nasal cavity filter mantle. This breathing filter, the draw -in groove card that earlier supports the cover top with the nasal surface according to user's demand during the use on flexible joint spare on the suitable transverse connection strip, again with the joint dogging on the flexible joint spare in the middle of the top of gauze mask, can install breathing filter on the gauze mask. When people breathed in, outside air at first carried out first time through the gauze mask body and filters, and then carried out secondary filter through the nasal cavity filter mantle, effectively avoided the fine particles suction health of people in with the air, was of value to the healthy of people.
Description
(1) technical field
The utility model relates to a kind of breathing circuit filter.
(2) background technology
Be subject to after air that vehicle exhaust and industrial waste pollute sucked health by people, very large threat to be brought to the healthy of people.Therefore, when air ambient is poor, in order to reduce the harm that contaminated air brings to people's health, people need to wear mouth mask, filter to carry out self-protection to the dust etc. in air.But, traditional Respirator structure is simple, only face mask body being located at people in use, because nose is given prominence at face, mask body and people face and nose both sides leave gap, fine particle in air can enter into inside mouth mask from gap with air-flow, is drawn in body by people, effectively can not play protective action.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides the breathing circuit filter that a kind of structure is simple, reasonable in design, mount and dismount convenience, good dustproof effect, solves problems of the prior art.
The utility model is achieved by the following technical solution:
A kind of breathing circuit filter, comprise a nasal surface support cover and for nasal surface support cover being connected to the flexible shackle member that mouth mask uses, a filtration supporting spring is provided with in the below of nasal surface support cover, arranged on left and right sides limit and the outer side edges of described filtration supporting spring engage with the base of nasal surface support cover, and filtration supporting spring is embedded with two nasal cavity filtering covers matched with human body nasal cavity.
Described flexible shackle member comprises two vertical supporting bars, some lateral connection bars are provided with between two vertical supporting bars, the top of described vertical supporting bar is provided with a clamping hook, and be provided with a draw-in groove at the top of nasal surface support cover, described draw-in groove is fastened on lateral connection bar.
The material of described filtration supporting spring and nasal cavity filtering cover is filter cotton.
The material of described filtration supporting spring and nasal cavity filtering cover is activated carbon filter layer.
The beneficial effects of the utility model are: this breathing circuit filter, first according to the demand of user, the draw-in groove at nasal surface support cover top is stuck on lateral connection bar suitable in flexible shackle member during use, again the clamping hook in flexible shackle member is stuck in the crown center of mouth mask, breathing circuit filter can be arranged on mouth mask.After mouth mask is worn on face, the position of adjustment nasal surface support cover, makes it just be attached on the nose of user, and the adjustment of filtration supporting spring is positioned at the underthe nose of user, is extend into respectively in the nasal cavity of user by two nasal cavity filtering covers.During people's air-breathing, first outside air carries out first time by mask body and filters, and then carries out second time filtration by nasal cavity filtering cover, effectively avoids people that the fine particle in air is sucked health, is of value to the healthy of people.And, the utility model breathing circuit filter can easily and mouth mask between install or remove, easy to use.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the right TV structure schematic diagram of Fig. 1;
Fig. 4 is the structural representation after taking off flexible shackle member in Fig. 3.
In figure, 1 nasal surface support cover, 2 filter supporting spring, 3 nasal cavity filtering covers, 4 vertical supporting bars, 5 lateral connection bars, 6 clamping hooks, 7 draw-in grooves.
(5) detailed description of the invention
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Fig. 1-Fig. 4, this embodiment comprises a nasal surface support cover 1 and for nasal surface support cover 1 being connected to the flexible shackle member that mouth mask uses, a filtration supporting spring 2 is provided with in the below of nasal surface support cover 1, arranged on left and right sides limit and the outer side edges of described filtration supporting spring 2 engage with the base of nasal surface support cover 1, and filtration supporting spring 2 is embedded with two nasal cavity filtering covers 3 matched with human body nasal cavity.
Described flexible shackle member comprises two vertical supporting bars 4, some lateral connection bars 5 are provided with between two vertical supporting bars 4, the top of described vertical supporting bar 4 is provided with a clamping hook 6, is provided with a draw-in groove 7 at the top of nasal surface support cover 1, and described draw-in groove 7 is fastened on lateral connection bar 5.
The material of described filtration supporting spring 2 and nasal cavity filtering cover 3 is filter cotton.
The material of described filtration supporting spring 2 and nasal cavity filtering cover 3 is activated carbon filter layer.
During use, first according to the demand of user, the draw-in groove 7 at nasal surface support cover 1 top is stuck on lateral connection bar 5 suitable in flexible shackle member, then the clamping hook 6 in flexible shackle member is stuck in the crown center of mouth mask, breathing circuit filter can be arranged on mouth mask.After mouth mask is worn on face, the position of adjustment nasal surface support cover 1, makes it just be attached on the nose of user, and the adjustment of filtration supporting spring 2 is positioned at the underthe nose of user, is extend into respectively in the nasal cavity of user by two nasal cavity filtering covers 3.During people's air-breathing, first outside air carries out first time by mask body and filters, and then carries out second time filtration by nasal cavity filtering cover 3, effectively avoids people that the fine particle in air is sucked health, is of value to the healthy of people.And, the utility model breathing circuit filter can easily and mouth mask between install or remove, easy to use.
