Abstract
The utility model relates to a flexible air pipe which comprises a flexible air pipe body which is made of polyester fibers. A channel where air flow passes is formed in the flexible pipe body, and supporting devices are arranged in the channel at intervals. When the channel is in a negative pressure state, the supporting device can support up the channel. According to the flexible air pipe, the supporting device are arranged in the channel at intervals, the supporting device can support up the channel when the channel is in the negative pressure state, and accordingly the problem that the channel is shrunken and cannot exhaust air when negative pressure is formed in the pipe is solved. Meanwhile, the flexible air pipe body is made of polyester fibers, so that the flexible air pipe body is convenient to clean when the supporting devices are taken away.
Description
Technical field
The utility model relates to a kind of improvement of airduct, and especially a kind of cost is low, be convenient to clean, and the pneumatic hose that can use under negative pressure state.
Background technique
Because airduct is used mostly in megastore, factory, the public places such as gymnasium, thus must possess following characteristic, first, fire-retardant, must meet national fire-protection standard; The second, antistatic; Three, mildew-resistant, antibiotic; Therefore traditional airduct is made with galvanized sheet iron conventionally, and this airduct has following deficiency, and one, galvanized sheet iron are difficult to clean thoroughly, and it is very high to clean cost, thereby affect IAQ; Two, iron duct cannot be accomplished station air supply, uneven air; Three, iron duct cost is high, and difficulty is installed.
Model utility content
The utility model object is in order to overcome above-mentioned shortcoming, provide a kind of cost low, be convenient to clean and the pneumatic hose that can use under negative pressure state.
For achieving the above object, the technical solution of the utility model is: a kind of pneumatic hose, comprises pneumatic hose body; Described pneumatic hose body is to be made by polyester fibre; In described pneumatic hose body, be provided with the passage of airflow passes; In described passage, compartment of terrain is provided with support device; When passage is during in negative pressure state, described support device can support passage.
Preferably, described support device is a circle; Described circle is spaced apart and arranged in vias inner walls.
Preferably, described support device is polygonal framework; Described polygonal framework is spaced apart and arranged in vias inner walls.
Preferably, described support device is quadrilateral framework; Described quadrilateral framework is spaced apart and arranged in vias inner walls.
Owing to having adopted such scheme the utility model compared with prior art to there is following beneficial effect:
Pneumatic hose described in the utility model, in described passage, compartment of terrain is provided with support device; When passage is during in negative pressure state, described support device can support passage; So just solved in pipe gas and become negative pressure just to there will be flatly to fall, problem that cannot air draft, simultaneously because described pneumatic hose body is to be made by polyester fibre, after support device is taken off, can conveniently clean.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1 is the first embodiment's of pneumatic hose described in the utility model sectional view;
Fig. 2 is the second embodiment's of pneumatic hose described in the utility model sectional view;
Wherein: 1, pneumatic hose body; 2, support device.
embodiment
Below in conjunction with accompanying drawing example, structure of the present utility model is described in further detail:
A kind of pneumatic hose described in the first embodiment of the present utility model as shown in Figure 1, comprises pneumatic hose body 1; Described pneumatic hose body 1 is to be made by polyester fibre; In described pneumatic hose body 1, be provided with the passage (not marking) of airflow passes; In described passage, compartment of terrain is provided with support device 2; When passage is during in negative pressure state, described support device 2 can support passage; Described support device 2 is a circle; Described circle is spaced apart and arranged in vias inner walls.
A kind of pneumatic hose described in the second embodiment of the present utility model as shown in Figure 2, comprises pneumatic hose body 1; Described pneumatic hose body 1 is to be made by polyester fibre; In described pneumatic hose body 1, be provided with the passage of airflow passes; In described passage, compartment of terrain is provided with support device 2; When passage is during in negative pressure state, described support device 2 can support passage; Described support device 2 is quadrilateral framework; Described quadrilateral framework is spaced apart and arranged in vias inner walls.
Certainly, described support device also can be arranged to polygonal framework; Described polygonal framework is spaced apart and arranged in vias inner walls.
Owing to having adopted such scheme the utility model compared with prior art to there is following beneficial effect:
Pneumatic hose described in the utility model, in described passage, compartment of terrain is provided with support device; When passage is during in negative pressure state, described support device can support passage; So just solved in pipe gas and become negative pressure just to there will be flatly to fall, problem that cannot air draft, simultaneously because described pneumatic hose body is to be made by polyester fibre, after support device is taken off, can conveniently clean.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, within all dropping on the utility model rights protection scope.
