Abstract
The utility model discloses an air filter tube which comprises a respiratory tube, an elastic filter disc and a protective cover, and is characterized in that the elastic filter disc covers a front port of the respiratory tube, the upper edge of the elastic filter disc is mutually connected with the upper edge of the front port of the respiratory tube, the hollow protective cover is further arranged on the periphery of the elastic filter disc, and the cross section of the respiratory tube is oval so as to be applicable to being held in the mouth. The air filter tube has the characteristics of resources conservation and convenience use, as long as the air filter tube is held in the mouth, a person can breathe fresh air, when in inspiration, the elastic filter disc is jointed with the front port of the respiratory tube, the air enters into the respiratory tube after passing through the elastic filter disc for filtering and then is absorbed by a human body, when in expiration, the elastic filter disc is blown up by exhalent gas, thereby enabling the hot gas to be smoothly and fully exhausted from the respiratory tube, avoiding generating resistance and also preventing the hot gas from being transferred to the face part around the mouth and the nose.
Description
Technical field
The utility model relates to a kind of air filter, especially relates to a kind of air filtration pipe.
Background technology
At present, in order not influence health in air sordid place construction, people usually put on mouth mask and avoid sucking deleterious particles such as dust, but the volume of mouth mask is bigger, half face is all covered, because the resistance of mouth mask, it is gruelling to exhale, and the hot gas of breathing out is delivered to the face around the mouth and nose, makes the people very uncomfortable.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of air filtration pipe is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of air filtration pipe of the present utility model; it comprises respiratory siphon, elasticity filter disc and protective cover; it is characterized in that; the elasticity filter disc covers the front port of respiratory siphon; the top edge of the top edge of elasticity filter disc and respiratory siphon front port interconnects, and the periphery of elasticity filter disc also has the protective cover of a hollow out.
Described respiratory siphon, its cross section are oval, to be fit to rank in the mouth.
The utlity model has following beneficial effect:
A kind of air filtration pipe of the present utility model, have economize on resources, characteristics easy to use, as long as its rank just can had a breath of fresh air in the mouth, when air-breathing the front port of elasticity filter disc and respiratory siphon paste and, air enters respiratory siphon after filtering by the elasticity filter disc, is absorbed by the body, and the gas that the elasticity filter disc is breathed out during expiration blows afloat, make hot gas discharge respiratory siphon smoothly and fully, do not produce resistance and also can not allow hot gas be delivered to mouth and nose face on every side.
Description of drawings
Fig. 1 is the structural representation of a kind of air filtration pipe of the utility model.
Fig. 2 is the cross-sectional figure of a kind of air filtration pipe of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
With reference to Fig. 1; a kind of air filtration pipe; it comprises respiratory siphon 1, elasticity filter disc 2 and protective cover 3; it is characterized in that; elasticity filter disc 2 covers the front port 4 of respiratory siphon 1; the top edge 5 of elasticity filter disc 2 interconnects with the top edge 6 of the front port 4 of respiratory siphon 1, and the periphery of elasticity filter disc 2 also has the protective cover 3 of a hollow out.
With reference to figure 2, described respiratory siphon 1, its cross section are oval, to be fit to rank in the mouth.
During use, as long as its rank just can had a breath of fresh air in the mouth, when air-breathing the front port 4 of elasticity filter disc 2 and respiratory siphon 1 paste and, air enters respiratory siphon 1 after filtering by elasticity filter disc 2, be absorbed by the body, the gas that elasticity filter disc 2 is breathed out during expiration blows afloat, and makes hot gas discharge respiratory siphon 1 smoothly and fully, does not produce resistance and also can not allow hot gas be delivered to mouth and nose face on every side.
