Detailed Description

The utility model is further described below with reference to the drawings and examples. Referring to fig. 1 to 5, a pipeline structure with an increased indoor natural ventilation volume is composed of a main pipe 1 and a reducer pipe 2, wherein the reducer pipe 2 is in a horn shape, two ends of the main pipe 1 are connected with small ends of the reducer pipe 2, and an included angle beta of an opening of the reducer pipe 2 is 35-45 degrees (as shown in fig. 1 and 2).

A pipeline structure for increasing indoor natural ventilation is composed of main pipe 1 and reducer pipe 2, wherein the reducer pipe 2 is in horn shape, the main pipe 1 is divided into two sections, and the main pipe 1 and the reducer pipe are connected through corrugated pipes 3 (shown in figure 4).

A pipeline structure with an indoor natural ventilation capacity increasing function is composed of a main pipe 1 and a reducer pipe 2, wherein the reducer pipe 2 is in a horn shape, the main pipe 1 is divided into two sections, a T-shaped pipe 4 is connected between the main pipe 1 and the reducer pipe, and a movable wind shield 6 (shown in figure 5) is arranged in the T-shaped pipe 4.

The utility model is mainly arranged on a wall body 3, a through hole is firstly formed in the wall body 3, a main pipe 1 is installed through the wall, then two ends of the main pipe 1 are connected with a reducer pipe 2 (shown in figure 3) with a wind gathering function, the reducer pipe 2 is in a horn mouth shape, and an opening included angle beta is 45 degrees. Fresh air outside the wall body 3 enters the room from the reducer pipe 2 under the action of natural wind force, and the reducer pipes 2 are arranged at the two ends of the wall body, so that the indoor air exchange with outdoor air is facilitated, namely, natural wind easily enters the room, and indoor air easily flows out of the room.

The utility model is used for improving the prior toilet, increases the ventilation effect of the public toilet, and the results of the field test are shown in the following table:

table 1 ventilation effect test basic data

Pipe diameter of main air pipe	Maximum diameter of reducer pipe	Wind speed of air inlet	Wind speed of air outlet
				150mm	450mm	2.1m/s	2.7m/s

The upper table is the device model size and test data manufactured by adopting iron sheets, and adopts an electric circulation fan to carry out a blowing test, and the wind speed of the wind inlet at the position of the maximum pipe diameter of the reducer pipe 2 is 2.1m/s, and the wind speed of the wind outlet at the position of the minimum pipe diameter of the reducer pipe at the other end is 2.7m/s, so that the pipeline has an obvious wind gathering function.

The utility model can divide the main pipe 1 into two sections, and then the two sections of main pipes 1 are sleeved by the corrugated pipe 3 (shown in figure 4) for improving the air mobility of the ground of a room and preventing harmful gas (such as radon gas) from depositing in the corner space of the room.

As shown in fig. 5, the main pipe 1 can be divided into two sections, a T-shaped pipe 4 with a movable wind shield 6 arranged in the main pipe 1 is connected between the two sections, when an air inlet enters the T-shaped pipe 4, the reducer pipe 2 at the other end is in a closed state, and air flows out from the air outlet of the straight pipe of the T-shaped pipe 4 (as shown in fig. 5). The T-shaped natural ventilation pipeline structure is arranged in a house in the south of the north of the seat, a window is opened in the south of the seat, south wind can blow into a room, north wind can enter from a door and exit from the window, but east wind and west wind cannot enter the room, the T-shaped natural ventilation pipeline structure can ensure that east and west wind can enter the room, the concentration of indoor harmful gas is reduced, and the T-shaped natural ventilation pipeline structure can be arranged outside a wall penetrating, balcony railing hanging or window hanging.
