Abstract

The utility model discloses a fresh air pipeline system which comprises an indoor cold air inlet pipe, an indoor hot air inlet pipe, an air mixing device and a mixed air outlet pipe, wherein the air mixing device comprises a cold air inlet, a hot air inlet and a plurality of air outlets; the air mixing device is reasonable and simple in structure, simple to operate and convenient to popularize and apply, the arrangement of the filter screen and the one-way valve of the air mixing device effectively ensures the cleanliness of air flow entering the air mixing device and prevents air flow from flowing back, and the design of the flat air pipe effectively reduces the requirement of air pipe installation on space.

Description

Fresh air pipeline system

Technical Field

The utility model relates to the field of fresh air pipe fittings, in particular to a fresh air pipeline system.

Background

The new trend system installation needs a large amount of pipe pavement, and the pipeline no matter sets up in the floor bottom or set up and all can occupy some spaces on the roof, no matter sets up there tuber pipe occupation space too big all can cause the influence to indoor height, often can slot on ground or the wall in order to reduce the occupy-place of tuber pipe in the work progress at present, this intensity of labour that will increase workman's construction and installation operation's complexity.

SUMMERY OF THE UTILITY MODEL

The present invention has been made to solve the above problems, and an object of the present invention is to provide a fresh air duct system.

The technical scheme adopted to solve the problems is as follows: the utility model provides a new wind pipe-line system, includes indoor cold wind air-supply line, indoor hot-blast air-supply line, mixes the wind device and mix the wind play tuber pipe, mix the wind device and include cold wind air intake, hot-blast air intake and a plurality of air outlet, the one end pipe of indoor cold wind air-supply line, indoor hot-blast air-supply line is connected with the cold wind air intake, the hot-blast air intake of mixing the wind device respectively, the other end communicates with the outside tuber pipe that provides the wind regime respectively, the air outlet communicates with each other with mixed wind play tuber pipe connection.

Further, as a preferred scheme of the present invention, the cold air inlet and the hot air inlet of the air mixing device are both provided with a check valve, so as to prevent air flow from flowing back due to different air flow pressures of the indoor cold air inlet pipe and the indoor hot air inlet pipe.

Further preferably, the flow direction of the check valve is from the outside to the inside of the air mixing device.

Further as the preferred scheme of the utility model, the air outlet is provided with an active carbon filter screen.

Further, as a preferred scheme of the utility model, the indoor cold air inlet pipe, the indoor hot air inlet pipe and the mixed air outlet pipe are flat.

The utility model has the beneficial effects that: simple, easy operation rational in infrastructure, facilitate promotion is used, mixes the cleanliness of the effectual air current that guarantees to get into the device of mixing wind of setting up of wind device filter screen and check valve and prevents the air current backward flow, and the effectual reduction tuber pipe of flat tuber pipe design is installed the requirement to the space.

Drawings

For ease of illustration, the utility model is described in detail by the following detailed description and the accompanying drawings.

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is an enlarged schematic view of a portion a of fig. 1 according to the present invention.

Detailed Description

As shown in fig. 1 and 2, a fresh air duct system includes an indoor cold air inlet duct 1, an indoor hot air inlet duct 2, an air mixing device 3 and a mixed air outlet duct 7, the air mixing device 3 includes a cold air inlet 4, a hot air inlet 5 and a plurality of air outlets 6, one end of each of the indoor cold air inlet duct 1 and the indoor hot air inlet duct 2 is respectively connected with the cold air inlet 4 and the hot air inlet 5 of the air mixing device 3, the other end of each of the indoor cold air inlet duct and the indoor hot air inlet duct is respectively communicated with an external air duct providing an air source, and the air outlets 6 are connected with the mixed air outlet duct 7 and communicated with each other.

Further, as a preferred embodiment of the present invention, the cold air inlet 4 and the hot air inlet 5 of the air mixing device 3 are both provided with a check valve 8, so as to prevent the air flow from flowing back due to the difference of the air flow pressures of the indoor cold air inlet pipe 1 and the indoor hot air inlet pipe 2.

Further, in a preferred embodiment of the present invention, the flow direction of the check valve 8 is from the outside to the inside of the air mixing device 3.

Further, as a preferred scheme of the present invention, an activated carbon filter screen 9 is disposed on the air outlet 6.

Further, as a preferred scheme of the present invention, the indoor cold air inlet pipe 1, the indoor hot air inlet pipe 2 and the mixed air outlet pipe 7 are flat.

While there have been shown and described what are at present considered to be the fundamental principles of the utility model and its essential features and advantages, it will be understood by those skilled in the art that the utility model is not limited by the embodiments described above, which are merely illustrative of the principles of the utility model, but that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
