The lower branch portions 300 and port portions 400 are arranged alternately between the portions 400 .

Figure 2 is an enlarged view of the main part of the pillar part according to the present invention, (a) a cross-sectional view and perspective view along line A-A of Figure 1, (b) a cross-sectional view and perspective view along line B-B of Figure 1, and Figure 3 is a pillar part and branches according to the present invention. This is an enlarged view of the main part of the unit, (a) a cross-sectional view and perspective view with the column portion and the branch portion separated, and (b) a cross-sectional view and a perspective view with the column portion and the branch portion combined.

Referring to FIGS. 2A and 2B, the power supply unit 800 of the pillar unit 200 is disposed in the center of the hollow, and a water intake pipe 620-1 and a water outlet pipe 630-1 are formed around the power supply unit 800. They are placed in pairs. In addition, according to one embodiment, three pairs of water inlet pipes 620-1 and water outlet pipes 630-1 are provided around the power unit 800.

At this time, in Figure 2a, the water intake pipe (620-1) and the water outlet pipe (630-1) at the bottom (first column column) are angled at 120 degrees at angles of 60 degrees, 180 degrees, and 300 degrees, based on the 12 o'clock direction. It is placed standing in an open position.

Meanwhile, referring to FIG. 2b, the LED light of the LED lighting unit 500 must be evenly irradiated to the lower upper and lower (column 1 and 2 stages) port parts 400 for plant growth, so the upper (column 2 tiers) The water intake pipe 620-1 and the water outlet pipe 630-1 are twisted and arranged at angles of 120 degrees, 240 degrees, and 0 degrees, respectively, by 120 degrees based on the 12 o'clock direction.

That is, a total of six port portions 400, three each at the top and bottom (columns 1 and 2), can be arranged at an angle of 60 degrees so that the portholes do not overlap, as shown in the plan view of FIG. 1B. Accordingly, all plant ports (P) inserted into and seated in each port hole (401) can uniformly receive the LED light necessary for plant growth from the LED lighting unit (500).

In addition, the water intake pipes 620-1 and 620-2 provided in the pillar portion 200 and the branch portion 300 have different pipe diameters. Likewise, the water outlet pipes 630-1 and 630-2 also have different pipe diameters.

For example, the diameter of the water intake pipe 620-2 and the water outlet pipe 630-2 provided in the branch portion 300 is the diameter of the water intake pipe 620-1 and the water outlet pipe 630 provided in the pillar portion 200. -1) It is formed smaller than the pipe diameter. Therefore, when assembling the pillar portion 200 and the branch portion 300 with each other, the water intake pipes 620-1, 620-2 and water outlet pipes 630-1, 630-2 having different pipe diameters as described above are constrained to each other. Connect by pressing.

Due to the narrowing of the pipe diameter described above, even if the nutrient solution flowing in from the intake pipe 620-1 of the pillar portion 200, which has a relatively large pipe diameter, branches into three branches through the branch portion 300, the pipe diameter is relatively small. The hydraulic pressure of the water intake pipe 620-2 of the branch portion 300 is maintained above a certain pressure. Accordingly, as described above, the nutrient solution of a certain pressure or more may be sprayed from the water intake pipe 620-2 of the branch portion 300 toward the plant roots inside the port portion 400. For example, the spraying of the nutrient solution can be configured to automatically spray the nutrient solution at regular intervals by adding components such as a timer (not shown).

In addition, referring to Figure 3, between the water intake pipes (620-1, 620-2) and the water outlet pipes (630-1, 630-2) of the pillar portion 200 and the branch portion 300, rubber is provided to prevent leakage. Packing 640 is further provided. Accordingly, the water intake pipe 620-2 and the water outlet pipe 630-2 of the branch portion 300 are constrained to the hollow of the water intake pipe 620-1 and the water outlet pipe 630-1 of the pillar portion 200. When connecting by fitting, a rubber packing may be inserted between the water intake pipes (620-1, 620-2) and the water outlet pipes (630-1, 630-2).

In addition, the coupled ends of the pillar portion 200 and the branch portion 300, where the water intake pipes (620-1, 620-2) and the water outlet pipes (630-1, 630-2) are connected, are held by hand and turned. A coupling member 700 that couples the outer diameters of the pillar portion 200 and the branch portion 300 by a screw coupling method is further provided.

Therefore, the user is in a state in which the water intake pipes 620-1, 620-2 and the water outlet pipes 630-1, 630-2 of the branch portion 300 and the pillar portion 200 are separated from each other as shown in FIG. 3A. Pressure fit the water intake pipe (620-2) and the water outlet pipe (630-2) of the branch portion (300) to the inner diameter of the water intake pipe (620-1) and the water outlet pipe (630-1) of the pillar portion (200). They are joined together by pressing them together.

Subsequently, the user lifts the coupling member 700 provided around the pillar portion 200 upward and rotates it in one direction, so that the screw thread 701 formed on the inner diameter of the coupling member 700 is branched ( As shown in FIG. 3B, the pillar portion 200 and the branch portion 300 are coupled to each other by the coupling member 700 by screwing into the screw groove 301 formed on the outer diameter of the 300.

On the other hand, when it is desired to disassemble the pillar portion 200 and the branch portion 300 again, the coupling member 700 is rotated in the opposite direction according to the reverse order described above to release the coupling, and then the branch portion 300 is reattached to the pillar portion.

Figure 4 is an enlarged view of the main portion of the port portion and the branch portion according to the present invention, showing the case where (a) the cross-sectional shape of the port portion is an inverted trapezoid at the bottom, (b) a hemisphere at the bottom, and (c) an inverted triangular pyramid at the bottom; This is an example diagram showing various planar shapes of the port portion according to the invention.

According to one embodiment, an inlet port 621 is further provided at the end of the inlet pipe 620-2 disposed inside the port portion 400. Accordingly, the nutrient solution is sprayed toward the roots of the plant seated in the port portion 400.

This is because, as described above, the diameter of the water intake pipe 620-2 of the branch portion 300 is smaller than the diameter of the water intake pipe 620-1 of the pillar portion 200, the branch portion 300 branches into three branches. It is understandable that the pressure inside the water intake pipe 620-2 is maintained so that it can be sprayed.

In addition, referring to FIG. 4, a rubber packing ( 640) is further provided.

In addition, the water outlet pipe (630-2) is disposed below the water intake pipe (620-2), so that when the injected nutrient solution reaches a certain level inside the port portion (400), the nutrient solution is discharged through the water outlet pipe (630-2). It is recovered into the nutrient solution tank (T) inside the main body 100.

Additionally, referring to FIG. 5, the port portion 400 according to the present invention may be implemented in various shapes such as a leaf shape, a flower shape, or a star shape when viewed from a plan view.

This is an example showing how the LED lighting unit displays various air quality measurement conditions.

Referring to FIG. 6, the LED lighting unit 500 according to the present invention may be implemented in a round disk or dish shape, according to one embodiment. Referring to the front view, a lighting switch 510 may be provided on one front side of the LED lighting unit 500 to turn the power on/off or adjust the brightness of the LED lighting unit 500.

In addition, referring to Figure 7, according to one embodiment, the LED lighting unit 500 and the pillar unit 200 coupled thereto have a locking protrusion 501 and an 'ㄱ' shaped locking groove 201 at the top, respectively. It is provided.

Hereinafter, we will look at the process of coupling the LED lighting unit 500 to the pillar unit 200 in more detail.

First, referring to FIG. 7A, in a state where the LED lighting unit 500 is separated from the pillar unit 200, the user attaches the LED lighting unit 500 to the uppermost part of the pillar unit 200. At this time, as shown in the cross-sectional view of FIG. 7A, LED power terminals 801 and 802 are provided in the hollow portions of the pillar portion 200 and the LED lighting portion 500, respectively. Therefore, when the user connects the LED lighting unit 500 to the pillar unit 200, the respective LED power terminals 801 and 802 are also connected.

Referring to Figure 7b, as described above, when attempting to couple the LED lighting unit 500 to the pillar unit 200 in a state where the LED lighting unit 500 and the pillar unit 200 are separated, the LED lighting unit 500 must first be connected to the pillar unit 200. With the locking protrusion 501 inserted into the locking groove 201 of the pillar 200, the locking protrusion 501 is rotated in one direction (to the right in the drawing) along the horizontal groove 201a of the locking groove 201 until the end. (Arrow No. 1). In this state, the LED power terminals 801 and 802 of the pillar portion 200 and the LED lighting portion 500 are aligned with each other so that they can be snugly fitted with each other.

Continuing, this time, the user presses the locking protrusion 501 downward along the vertical groove 201b of the locking groove 201 (arrow 2), thereby powering the LED lighting unit 500 and the pillar unit 200. The terminals 801 and 802 are electrically connected by being inserted into each other. (Refer to the ‘separated state’ diagram at the top of Figure 7c)

Meanwhile, referring to FIG. 7C, when attempting to disassemble the LED lighting unit 500 and the pillar unit 200 to which the LED power terminals 801 and 802 are coupled and connected as described above, first lock them in the reverse order of the above-described process. After pushing the protrusion 501 upward (arrow 1), this time rotating the locking protrusion 501 (arrow 2) in the opposite direction (to the left in the drawing) along the horizontal groove of the locking groove, the LED lighting unit 500 becomes detachable from the pillar portion 200. (Refer to the ‘combined state’ diagram at the bottom of Figure 7c)

Meanwhile, the LED lighting unit 500 may be further equipped with an air quality measurement sensor (not shown). Accordingly, the color of the LED lighting unit 500 may be expressed differently depending on the measured value of the air quality measurement sensor (not shown). For example, the air quality measurement sensor (not shown) may be a fine dust measurement sensor that measures air quality by measuring the concentration of fine dust contained in the air.

For example, the air quality measurement sensor (not shown) may be composed of a light emitting part, a light receiving part, a heater, etc., and when the heater is heated, the air inside the sensor is warmed and the warmed air inside the sensor flows out of the sensor due to a convection phenomenon. Indoor air flows into the sensor. At this time, as the air flows inside the sensor, the light emitted from the light emitting unit is scattered by fine dust in the air, and the light receiving unit detects the degree of scattering of the light and measures the concentration of fine dust.

In addition, referring to Figure 8, the LED lighting unit 500 of the present invention includes a temperature and humidity sensor, a motion sensor, and an illumination intensity sensor in addition to the vegetation LED 521 that irradiates the LED light necessary for plant growth and the air quality measurement sensor (not shown). Sensors, etc. may be additionally included, and may be divided into status display LEDs 522 linked thereto.

Accordingly, the status display LED 522 displays different colors depending on the air quality measurement value of the air quality measurement sensor (not shown), allowing the user to determine the indoor air quality status at a glance. For example, the color of the status display LED 522 may be expressed differently as good: blue, normal: green, bad: orange, very bad: red, etc.

Additionally, a variety of plasma ion generators, negative ion generators, UV sterilizers, or timers can be optionally added to the device of the present invention.

In addition, the present invention is not limited to just one embodiment described above, and the same effect can be created even when changing the detailed configuration, number, and arrangement structure of the device, so those skilled in the art will understand the present invention. It is stated that addition, deletion, and modification of various configurations are possible within the scope of the technical idea.
