Abstract

The present disclosure relates to a plant cultivator, and more specifically, to an open plant cultivator that, by disposing a light source part having a plurality of light source elements on the horizontal extension part of the handle, can generate a sufficient amount of light to grow a plurality of plants, and can evenly transmit the light generated to a cultivation port part.

First claim

1 . A plant cultivator comprising:
a cultivation package; a main body on which the cultivation package is detachably disposed; a light source configured to emit light toward the cultivation package; and a housing disposed above the main body and configured to accommodate the light source; wherein the housing is spaced apart from an upper surface of the cultivation package and includes a horizontal extension extending across the upper surface of the cultivation package, and wherein the light source is disposed inside the horizontal extension of the housing.

2 . The plant cultivator of claim 1 ,
wherein the light source includes:
a circuit board disposed to extend parallel to the upper surface of the cultivation package and having a length in a left and right direction that is larger than a width of the circuit board in a front and rear direction; and
a plurality of light source elements configured to generate the light emitted toward the cultivation package and disposed on the circuit board.

3 . The plant cultivator of claim 2 ,
wherein the plurality of light source elements are located above and laterally inside of an area of the upper surface of the cultivation package.

4 . The plant cultivator of claim 2 ,
wherein the plurality of light source elements include:
a plurality of first light source elements arranged on a first extension line extending along a longitudinal direction of the circuit board; and
a plurality of second light source elements arranged on a second extension line extending along the longitudinal direction of the circuit board, the second extension line being spaced apart from the first extension line.

5 . The plant cultivator of claim 4 ,
wherein the first extension line and the second extension line are parallel to each other.

6 . The plant cultivator of claim 4 ,
wherein a spacing between the plurality of first light source elements in the left and right direction is constant, and a spacing between the plurality of second light source elements in the left and right direction is constant.

7 . The plant cultivator of claim 4 ,
wherein a spacing between the plurality of first light source elements in the left and right direction is varied along the first extension line, and a spacing between the plurality of second light source elements in the left and right direction is varied along the second extension line.

8 . The plant cultivator of claim 7 ,
wherein the spacing between the plurality of first light source elements in the left and right direction gradually becomes smaller away from a center of the horizontal extension, and the spacing between the plurality of second light source elements in the left and right direction gradually becomes smaller away from the center of the horizontal extension.

9 . The plant cultivator of claim 2 ,
wherein the horizontal extension includes a plurality of light transmission holes that are open toward an upper surface of the cultivation package, and the light generated by the plurality of light source elements passes through the plurality of light transmission holes.

10 . The plant cultivator of claim 9 ,
wherein each of the plurality of light source elements is disposed to emit light, respectively, through a corresponding one of the plurality of light transmission holes.

11 . The plant cultivator of claim 10 ,
wherein each of the plurality of light source elements is at least partially inserted, respectively, into the corresponding one of the plurality light transmission holes.

12 . The plant cultivator of claim 10 ,
wherein each of the plurality of light transmission holes has an upper opening that opens in an upward direction and into which a corresponding one of the plurality of light source elements is at least partially inserted, and a lower opening that opens in a downward direction, and wherein a cross-section area of the lower opening is greater than a cross-section area of the upper opening.

13 . The plant cultivator of claim 12 ,
wherein the housing further includes a transparent cover coupled to the horizontal extension, disposed below the lower openings, and through which light generated by the plurality of light source elements passes; and wherein the transparent cover includes a condensing lens that is convex toward the lower opening.

14 . The plant cultivator of claim 13 ,
wherein the condensing lens extends linearly in the left and right direction, and a width in the front and rear direction is constant along the left and right direction.

15 . The plant cultivator of claim 14 ,
wherein the width of the condensing lens in the front and rear direction is greater than a width of each of the plurality of light transmission holes in the front and rear direction.

16 . The plant cultivator of claim 1 ,
wherein the housing includes:
a first downward extension having an upper end portion which is connected to a left end portion of the horizontal extension and a lower end portion which is detachably connected to the main body; and
a second downward extension having an upper end portion which is connected to a right end portion of the horizontal extension and a lower end portion which is detachably connected to the main body;
wherein the first downward extension includes a first ventilation hole that communicates with an inside of the horizontal extension, and wherein the second downward extension includes a second ventilation hole that communicates with the inside of the horizontal extension.

17 . The plant cultivator of claim 16 ,
wherein the first ventilation hole and the second ventilation hole are disposed to be spaced apart from each other with the light source interposed therebetween.

18 . The plant cultivator of claim 1 , further comprising:
a wireless communications interface; and an input device, wherein the light source includes a controller configured to manage the light emitted toward the cultivation package based on a signal received from at least one of the wireless communications interface or the input device:

19 . A plant cultivator comprising:
a main body in which a cultivation medium is received; a housing detachably coupled to the main body, the housing defining an accommodation space and including a plurality of openings; a light source provided in the accommodation space and configured to output light toward the cultivation medium through the plurality of openings; and a condensing lens provided in the accommodation space between the light source and the plurality of openings, the condensing lens extending along an extension direction of the housing.

20 . A plant cultivator comprising:
a main body; a water tank coupled to main body and defining a cavity to receive a cultivation package and a cultivation liquid; a housing detachably coupled to the water tank; and a plurality of light source elements provided in the housing and including:
first light source elements provided on a first extension line extending along a longitudinal direction of the housing; and
second light source elements provided on a second extension line extending along the longitudinal direction of the housing and parallel to the first extension line.
