Description

Nose mask with external connecting pipe

Technical Field

The utility model particularly relates to a nose cup with an external connecting pipe.

Background

In an environment with air pollution, in order to prevent harmful substances such as dust, bacteria, viruses and the like in the surrounding environment from entering a respiratory system, a filtering device capable of filtering air inhaled by a nose is required in life or work, so that the occurrence of diseases is prevented, and the harm of external air pollution to human bodies is reduced.

The nose breathing filter device commonly used at present has a nose cover and the like, but in practical use, the structure of the nose cover is that a filter disc is arranged on a nose cover body, the nose cover body is directly attached to the nose, and no enough space exists between the nose and the filter disc to disperse gas exhaled by the nose, so that the exhaled gas is intensively dispersed on the face. If a person wearing the helmet or the pair of glasses uses the nose mask, the water vapor exhaled by the nose is easily pasted on helmet protective glasses or the pair of glasses, the sight is affected, and the adverse effect is generated on the user.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model lies in providing a take external nose cup of takeing over, can draw the nose cup with the gas of exhalation external, prevent that the gas that has steam of exhalation from concentrating and spreading at the face, and lead to steam to paste on helmet goggles or glasses, influence the sight to and produce the scheduling problem of breathing out.

The utility model discloses a realize like this:

the nose mask comprises a nose mask body, an air inlet pipe, an air outlet pipe, an air inlet one-way valve, an air outlet one-way valve and two air exchange covers, wherein two through holes are formed in the positions, corresponding to nostrils, on the nose mask body, the through holes are respectively communicated with the air inlet pipe and the air outlet pipe, the air inlet one-way valve is arranged on the air inlet pipe, the air outlet one-way valve is arranged on the air outlet pipe, the other ends of the air inlet pipe and the air outlet pipe are respectively communicated with the corresponding air exchange covers, and a filter chip is arranged at the position, communicated with the outside air.

Furthermore, the left side and the right side of the nose mask body are provided with fixing belts.

The utility model has the advantages that:

the nose mask body of the utility model is connected with the air outlet pipe, which can discharge the gas exhaled by the human body from the air outlet pipe, and prevent the exhaled gas with water vapor from being concentrated and spread on the face, so that the water vapor is stuck on helmet protective glasses or glasses; the air inlet pipe and the air outlet pipe are both provided with one-way valves, so that the gas entering or exiting can only flow along a set one-way direction, and cannot be suffocated; the utility model discloses be provided with the cover of taking a breath, and take a breath the cover and be provided with filter chip with the communicating department of outside air, when taking a breath with outside air, the gas that gets into or go out has all played the effect of protection through filter chip's filtration.

Drawings

The invention will be further described with reference to the following examples with reference to the accompanying drawings.

Fig. 1 is a schematic view of the nasal mask with external connection tube of the present invention.

Detailed Description

The embodiment of the utility model provides a through providing a take external nose cup of taking over, the user who has solved current gauze mask or nose cup can only carry out gas exchange in the orofacial portion when breathing, the technical problem of easy fogging when using face guard or closed helmet, it is external to have realized drawing forth the nose cup with the gas of exhalation, prevent that the gas that has steam of exhalation from concentrating and spreading in the face, and lead to steam to paste on helmet goggles or glasses, influence the sight, and produce the technological effect of suffocating etc.

For better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the embodiments.

Please refer to fig. 1, the utility model discloses a nose mask with external pipe, including a nose mask body 1, intake pipe 2, outlet duct 3, check valve 4 admits air, the check valve 5 and two covers of taking a breath of giving vent to anger 6, the nostril department of correspondence on the nose mask body 1 is provided with two through-holes 11, two through-hole 11 is linked together with intake pipe 2 and outlet duct 3 respectively, the check valve 4 that admits air sets up in intake pipe 2, the check valve 5 that gives vent to anger sets up on outlet duct 3, the other end of intake pipe 2 and outlet duct 3 is linked together with corresponding cover of taking a breath 6 respectively, each cover of taking a breath 6 and the communicating department of ambient air are provided with filter chip 61.

In one embodiment, the following is preferred: the left and right sides of the mask body 1 are provided with fixing bands 7.

In another embodiment of the present invention, the air inlet check valve 4 may be disposed at the head end or the tail end of the air inlet pipe 2; the air outlet one-way valve 5 can be arranged at the head end or the tail end of the air outlet pipe 3.

The working process of the utility model is as follows:

the nose mask body 1 is worn at the nose by using a fixing belt 7, and the ventilation mask 6 can be fixed on the body of a user by a fixing part; when a user inhales, outside air enters the ventilation cover 6 after being filtered by the filter chip 61 of the ventilation cover 6, then enters the nose mask body 1 along the air inlet pipe 2 through the air inlet one-way valve 4, and is inhaled by the human body.

When the nose mask body 1 is used for breathing, the contact part of the nose mask body 1 and the face is closed, so that gas flows along the gas outlet pipe 3 through the through hole 11, then enters the inside of the ventilation cover 6 through the gas outlet one-way valve 51, and finally is filtered by the filter chip 61 and then is discharged to the outside.

The nose mask body 1 of the utility model is connected with the air outlet pipe 3, which can discharge the gas exhaled by the human body from the air outlet pipe 3, and prevent the exhaled gas with water vapor from being intensively spread on the face, so that the water vapor is stuck on helmet protective glasses or glasses; the air inlet pipe 2 and the air outlet pipe 3 are both provided with one-way valves, so that the gas entering or exiting can only flow along a set one-way direction, and cannot be suffocated; the utility model discloses be provided with the cover 6 of taking a breath, and take a breath cover 6 and the communicating department of outside air is provided with filter chip 61, when taking a breath with the outside air, and the gas that gets into or go out has all played the effect of protection through the filtration of filtering chip 61.

Although specific embodiments of the present invention have been described, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the claims appended hereto.
