Detailed ways

The present utility model is further explained below in conjunction with the accompanying drawings.

As shown in FIG. 1 , in the growth chamber air circulation system device of the first embodiment, the growth chamber 1 is rectangular, the air inlet 2 and the air outlet 3 are arranged on the side wall of the growth chamber 1, the inlet of the air inlet 2 is connected with a fan 21, and the fan For blowing air to the inside of the growth chamber 1, the inside of the growth chamber 1 is also provided with a circular main air supply pipe 4 that is connected with the outlet of the air inlet 2, and the main air supply pipe 4 is longitudinally arranged on the top wall of the growth chamber 1 and the length is the same as the top wall. The lengths are the same, a plurality of circular secondary air transmission pipes 5 are vertically connected in the horizontal plane of the main air transmission pipe 4, and the spacing between the plurality of secondary air transmission pipes 5 is equal to cover the entire top wall, and the lower part of the secondary air transmission pipe 5 is arranged with a plurality of Holes 51, the distances between the plurality of holes 51 are equal.

When in use, the fan 21 drives the wind from the air inlet 2 to enter the main air transmission pipe 4, and then enters the secondary air transmission pipe 5, and enters the interior of the growth chamber 1 through the hole 51 on the secondary air transmission pipe 5, so that fresh air enters the interior of the growth chamber. , the excess air is discharged from the air outlet 3 on the side wall of the growth chamber to complete the circulation of the air in the growth chamber. Compared with the traditional air circulation device composed of an intake fan and an exhaust fan, the system device can make fresh air reach each of the growth chambers at the same time. In the corners, the air intake is uniform and the air intake method is gentle, which will not affect the growing indoor plants due to excessive wind speed, complete the air exchange in the growing room, and the air circulation effect is good.

As shown in FIG. 2 , the difference between the growth chamber air circulation system device of the second embodiment of the present invention and the first embodiment is that the main air supply pipe 4 is arranged along the diagonal of the rectangular growth chamber, and the secondary The air transmission pipe 5 is arranged perpendicular to the main air transmission pipe 4 in the horizontal plane. This setting makes the linear distance from the main air transmission pipe 4 to the end of the secondary air transmission pipe 5 shortened, and the fresh air can be completed in a shorter time to grow. Everywhere in the chamber, the air circulation effect is better; the shape of the growth chamber 1 can also be other shapes such as circle, trapezoid or regular polygon, and the main air duct 5 can be arc-shaped or linearly arranged on the top wall of the growth chamber.

As shown in Figure 3, the side view of the secondary air supply pipe 5 on the top wall of the growth chamber 1, the distances between the multiple circular secondary air supply pipes 5 are equal, and the diameter of the secondary air supply pipe 5 increases by equal differences, The diameter of the secondary air supply pipe 5 that is closest to the air inlet 2 is the smallest, and the diameter of the secondary air transmission pipe 5 that is farthest from the air inlet 2 is the largest, so that each secondary air transmission pipe 5 is set in the same time. The output air volume is the same, keeping the air intake in the growth chamber 1 uniform, and the air circulation is more balanced.

As shown in FIG. 4 , a water delivery pipe 6 is arranged in the secondary air delivery pipe 5, and a water outlet 61 is provided at each hole 51 of the water delivery pipe 6. The water source of the water delivery pipe 6 can be connected to tap water or a rainwater storage tank on the top of the growth chamber 1. , when it is necessary to irrigate the plants in the growth chamber 1, open the main water valve 62 of the water pipe 6, and the water reaches the water pipe 6 in the secondary air pipe 5 under the action of gravity or tap water pressure, and from The water outlet 61 drips everywhere, and drips from the hole 51 on the soil where the indoor plants are grown to complete the accurate drip irrigation of the plants. This design method can make the water reach the vegetation that needs to be irrigated accurately, reduce the waste of water, and at the same time, it can also make use of rainwater resources, save water resources and reduce costs.

The main air transmission pipe 4 and the secondary air transmission pipe 5 are preferably made of polypropylene or other plastic materials. The air transmission pipe is low in cost and light in weight. It requires less load-bearing structure of the growth chamber, reduces the cost input of the growth chamber, and has economic benefits. Good, and the humidity inside the growth chamber is high, the plastic air pipe will not rust, reducing equipment maintenance costs.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. These improvements and Retouching should also be regarded as the protection scope of the present invention.
