Description

plant cultivation device

[0001] The present disclosure relates to a plant cultivation device.

[0002] A plant cultivation device refers to a device that cultivates plants by artificially supplying the light and water necessary for plant growth.

[0003] Published Patent Application No. 10-2022-0059843 (hereinafter referred to as '843 document) discloses a plant cultivation device comprising a cultivation shelf on which a seed package is placed, a lighting device positioned above the cultivation shelf, and a pump that supplies water from a water tank to the cultivation shelf. The cultivation shelf, etc., is positioned in a cultivation space provided by a cabinet.

[0004] The cultivation space of the plant cultivation device in the above '843 document is separated from the outside through a cabinet, so it has an advantage in temperature and humidity control. However, it has the disadvantage of being bulky due to the cabinet.

[0005] Published Patent Application No. 10-2023-0099569 (hereinafter referred to as '569') discloses a plant cultivation device comprising a main body, a water tank portion seated on the main body, and a handle portion positioned above the water tank portion to irradiate light. Unlike the plant cultivation device of Patent No. 843, the plant cultivation device of '569 does not include a cabinet, thus having a smaller volume, and does not include a pump, etc., thus having a relatively simple configuration. Additionally, it is equipped with a handle for convenient movement and is equipped with a light source that irradiates light at the bottom of the handle.

[0006] Including a spacer connecting the handle and the main body of document '569, the height between the light and the main body can be adjusted, but the spacer must be attached and detached.

[0007] Published Patent Application No. 10-2019-0004178 (hereinafter referred to as '178') discloses a multi-stage plant cultivation device. '178 includes a plurality of cultivation units rotatable around a column portion. However, it discloses a feature in which the user can rotate the cultivation units to receive natural light evenly, rather than artificially irradiating the cultivation units with light.

[0008]

[0009] The present disclosure aims to solve the aforementioned problems and other problems.

[0010] Another objective may be to provide a plant cultivation device comprising a cultivation section spaced upward from a base on which a water tank and a pump are placed.

[0011] Another objective may be to provide a plant cultivation device that can adjust the height between the lighting unit and the cultivation unit.

[0012] Another objective may be to provide a plant cultivation device that can adjust the height between the lighting unit and the cultivation unit and be easily fixed.

[0013] Another objective may be to provide a plant cultivation device that can adjust the height between the lighting unit and the cultivation unit while separating the cultivation unit from the base.

[0014] Another objective may be to provide a plant cultivation device in which a water supply pipe and a second pipe are placed inside a first pipe positioned on the outside, and the interference between the water supply pipe and the second pipe is resolved.

[0015] Another objective may be to provide a plant cultivation device capable of separating and washing the cultivation unit.

[0016] Another objective may be to provide a stand-type plant cultivation device equipped with a mood light in addition to a cultivation light that illuminates the cultivation section.

[0017] Another objective may be to provide a plant cultivation device in which multiple cultivation units are arranged in an up-and-down direction and light can be irradiated onto each cultivation unit.

[0276] The lighting unit (80) is connected to the second pipe (62) and can rotate together with the second pipe (62). The first wire (181) is connected to the lighting unit (80) and can rotate together with the lighting unit and the second pipe (62).

[0277] The first wire (181) and the second wire (182) can be connected by a slip ring (65). When the second pipe (62) is rotated, the lighting unit (80) and the first wire (181) rotate together with the second pipe (62), but the second wire (182) may not rotate.

[0278] The holder (68) and the gas spring (64) can be connected by a rotator (66). When the second pipe (62) is rotated, the holder (68) rotates together with the second pipe (62), but the gas spring (64) may not rotate.

[0279] The second wire (182) can be extended spirally. The second wire (182) can be extended spirally around the gas spring (64). The second wire (182) can be extended spirally around the fixed part (63).

[0280] Through this, the wire can be extended in the up and down direction when the gas spring (64) is extended.

[0281]

[0282] Referring to FIGS. 13 and 14, the holder (68) can be coupled to the second pipe (62). The holder (68) may include an upper coupling portion (683) coupled to the second pipe (62). The upper coupling portion (683) may be inserted into the lower end of the second pipe (62). The holder (68) can rotate and move integrally with the second pipe (62).

[0283] A holder (68) may be placed in the hollow of the first pipe (61). The holder (68) may include a camshaft (687). The camshaft (687) may be placed parallel to the first pipe (61). The center (C2) of the camshaft (687) may be spaced apart from the center (C1) of the inner diameter of the first pipe (61) (see FIG. 15).

[0284] The holder (68) may include a first disk (685). The first disk (685) may be connected to the lower end of the upper coupling portion (683). The upper coupling portion (683) may extend upward from the first disk (685). The outer diameter of the first disk (685) may be larger than the inner diameter of the second pipe (62).

[0285] The first disk (685) may be positioned above the camshaft (687). The camshaft (687) may extend downward from the first disk (685). The second disk (685) may be positioned below the camshaft (687). The camshaft (687) may extend upward from the second disk (686). The camshaft (687) may extend between the first disk (685) and the second disk (686).

[0286] The diameter of the camshaft (687) may be smaller than the diameter of the first disk (685). The diameter of the camshaft (687) may be smaller than the diameter of the second disk (686).

[0287] The friction portion (67) may include an inner circumferential surface (677) forming a hollow (678). The hollow (678) may be radially open. A camshaft (687) may be inserted into the hollow (678) through the open portion.

[0288] The inner circumferential surface (677) can surround the camshaft (687). The inner circumferential surface (677) can rotatably support the camshaft (687).

[0289] The friction part (67) may be disposed in the hollow of the first pipe (61). The friction part (67) may be in contact with the inner circumference of the first pipe (61).

[0290] The friction portion (67) may include an outer surface (671). The outer surface (671) may be in contact with the inner circumference of the first pipe (61). The second pipe (62) and the lighting portion (80) may be supported on the first pipe (61) by the frictional force between the friction portion (67) and the inner diameter of the first pipe (61).

[0291] The outer surface (671) may have a gear shape. The outer surface (671) may include a protrusion (672) and a groove (673). The protrusion (672) and the groove (673) may be arranged alternately along the circumferential direction of the outer surface (671). The protrusion (672) may be in contact with the inner circumference of the first pipe (61), and the groove (673) may be spaced apart from the inner circumference. The protrusion (672) and the groove (673) may extend in the vertical direction.

[0292] Through this, the frictional force acting between the frictional part (67) and the inner circumference of the first pipe (61) when rotating the second pipe (62) may be greater than the frictional force acting between the frictional part (67) and the inner circumference of the first pipe (61) when moving the second pipe (62) up and down.

[0293]

[0294] Referring to FIG. 15, the radius (D3) of the friction part (67) in an uncompressed state may be larger than the radius (D1) of the inner circumference of the first pipe (61). Unless otherwise noted, the radius of the friction part refers to the distance from the center of the friction part to the outer surface of the protrusion (672).

[0295] The friction part (67) may be made of a material that is more flexible than the first pipe (61). For example, the friction part (67) may be made of rubber or synthetic resin, etc. The first pipe (61) may be made of metal or synthetic resin that is harder than the friction part (67).

[0296] For example, the friction part (67) may be made of ABS (Acrylonitrile, Butadiene, Styrene) resin or polyacetal (POM, Polyoxymetylene).

[0297] The friction part (67) can be pressed into the hollow of the first pipe (61).

[0298] The camshaft (687) can be in contact with the inner circumference (677) of the friction part (67) to provide the rotation center (c2) of the holder (68). When the second pipe (62) rotates, the friction part (67) is fixed to the first pipe (61), and the holder (68) can rotate around the center (c2) of the camshaft (687).

[0299] The radius (D2) of the disk (685, 686) may be smaller than the radius (D1) of the inner circumference of the first pipe (61). Thus, the holder (68) can rotate inside the first pipe (61).

[0300] The center (c2) of the camshaft (687) and / or the center of rotation (c2) of the holder (68) may be radially spaced from the center (c1) of the disk. Accordingly, any point located on the outer circumference of the disk (685, 686) may have its distance from the inner circumference of the first pipe (61) changed according to the rotation of the holder (68).

[0301] The disc (685, 686) may be made of a material that is more flexible than the first pipe (61). For example, the disc (685, 686) may be made of rubber or synthetic resin, etc. The first pipe (61) may be made of metal or synthetic resin that is harder than the disc (685, 686).

[0302] For example, the disc (685, 686) may be made of ABS (Acrylonitrile, Butadiene, Styrene) resin or polyacetal (POM, Polyoxymetylene).

[0303]

[0304] Referring to FIG. 16, all parts of the outer circumference of the disk (685, 686) may not come into contact with the inner circumference (613) of the first pipe (61) (state of FIG. 16(a)). When an upward and downward force is applied to the second pipe (62), the protrusion (672) of the friction part (67) comes into contact with the inner circumference (613) of the first pipe (61), so a frictional force acts between the friction part (67) and the first pipe (61). However, even if the frictional force (or the resultant force obtained by adding the force of the gas pipe described later to the frictional force) is applied, the second pipe (62) can be easily moved if the user applies an upward and downward force to the second pipe (62).

[0305] FIG. 16(b) shows that by rotating the holder (68) in FIG. 16(a) clockwise, a point (P2) on the outer circumference of the disk (685, 686) comes into contact with the inner circumference (613) of the first pipe (61), and FIG. 16(c) shows that by rotating the holder (68) in FIG. 16(a) counterclockwise, a point (P3) on the outer circumference of the disk (685, 686) comes into contact with the inner circumference (613) of the first pipe (61). Hereinafter, the points (P2, P3) are referred to as contact points (P2, P3).

[0306] The distance between the contact points (P2, P3) and the camshaft (687) is equal to the radius of the inner circumference (613) of the first pipe (61). Additionally, since the rotation center (c2) of the disk (685, 686) is spaced apart from the center (c3) of the inner circumference (613) of the first pipe (61), as the disk (685, 686) rotates, the contact points (P2, P3) may come into contact with or be spaced apart from the inner circumference of the first pipe (61).

[0307] Meanwhile, even if the center of rotation (c2) of the disk (685, 686) and the center (c3) of the inner circumference (613) of the first pipe (61) are positioned at the same location, if the inner circumference (613) of the first pipe (61) is not a perfect circle, the contact points (P2, P3) may come into contact with or be separated from the inner circumference of the first pipe (61) as the disk (685, 686) rotates.

[0308] The contact points (p2, p3) may come into contact with the inner circumference (613) of the first pipe (61) as the second pipe (62) rotates, thereby restricting the vertical movement of the second pipe (62). Alternatively, as in the state of FIG. 16(a), the contact points (p2, p3) may be separated from the inner circumference of the first pipe (61) as the second pipe (62) rotates, thereby releasing the restriction.

[0309] The points in the region (S1) corresponding to the arc connecting P2-P1-P3 on the outer circumference of the disk (685, 686) are at a distance from the center (C2) of the camshaft (687) that is less than D1, and the points in the other region, that is, the region (S2) corresponding to the arc connecting P2-P3, are at a distance from the center (C2) of the camshaft (687) that is greater than D1.

[0310] Accordingly, if the disk (658, 686) or the second pipe (62) is rotated further clockwise in the state of Fig. 16(b), or if the disk (658, 686) or the second pipe (62) is rotated further counterclockwise in the state of Fig. 16(c), the normal force pushing the outer surface of the disk (685, 686) against the inner surface (613) of the first pipe (61) increases, and the frictional force increases.

[0311] Through this, the position of the second pipe (62) can be fixed relative to the first pipe (61).

[0312]

[0313] Referring to FIG. 17, the gas spring (64) comprises a cylinder (644), a piston (641) disposed inside the cylinder (644) to divide the internal space of the cylinder into a first space (6441) and a second space (6442), and an orifice (6411) formed in the piston (641) to connect the first and second spaces (6441, 6442). The piston (641) may be provided with a rod (642) extending outside the cylinder (644), and a sealing (645) that seals the space between the rod (642) and the cylinder (644).

[0314] The internal space of the cylinder (6441, 6442) is filled with compressed gas and may contain a small amount of oil.

[0315] When no force is applied to the piston (641), the compressed gas can move between the first and second spaces (6441, 6442) through the orifice (6411), so the forces are in equilibrium.

[0316] When force is applied to the piston (641), the piston (641) can move along the cylinder (641) in the direction in which the force is applied.

[0317] For example, when force is applied to the piston (641) toward the first space (6441), the piston moves toward the first space (6441). At this time, as the volume of the first space (6441) decreases, the pressure increases, and as the volume of the second space (6442) increases, the pressure decreases. Due to the pressure difference, the compressed air in the first space (6441) passes through the orifice (6411) and moves to the second space; however, since the size of the orifice (6411) is small, the pressure cannot be balanced immediately as the piston moves, and resistance occurs.

[0318] Through this process, the gas spring (64) exerts a relatively constant repulsive force, unlike a general spring, where the elastic force changes in proportion to the displacement.

[0319] The gas spring (64) can be set to generate a desired repulsive force. For example, the repulsive force of the gas spring (64) can be set to be equal to the load of the lighting unit (80).

[0320] The first connecting part (643) can be connected to the bracket (634) of the fixed part (63), and the second connecting part (646) can be connected to the rotator (66).

[0321] Through this, the weight of the lighting unit (80) can be offset, and the second pipe (62) can be moved up and down with less force.

[0322] A first coupling part (643) is provided on the outer end of the rod (642), and a second coupling part (646) may be provided on the cylinder (644).

[0323]

[0324] Referring to FIGS. 18 and 19, the lighting unit (80) may be coupled to the second pipe (62). The lighting unit (80) may include a flange (86) coupled to the second pipe (62).

[0325] The flange (86) may include an inner flange (866) that is inserted into the upper end of the second pipe (62). The inner flange (866) may have an inner portion inserted into the second pipe (62) and an outer portion that extends radially. The inner flange (866) may be coupled to the second pipe (62).

[0326] The flange (86) may include an outer flange (861) positioned on the outside of the second pipe (62). The second pipe (62) may be inserted into the center of the outer flange (861). The outer flange (861) may extend radially. The outer flange (861) may be connected to the second pipe (62).

[0327] The inner flange (866) can be positioned on the upper side of the outer flange (861).

[0328] The lighting unit (80) may include a cultivation light (81). The cultivation light (81) may include a light-emitting body (811) that emits light. For example, the light-emitting body may be an LED (light-emitting diode). The LED (811) may be positioned facing downward.

[0329] The light bulb (81) may include a PCB (813, printed circuit board) on which an LED is installed. The LED (811) may be placed on the lower side of the PCB.

[0330] The light source (81) may include a cover (815). The cover (815) may include a hole at a position corresponding to the LED that widens as it moves away from the LED. Through this, the light emitted from the LED (811) can be diffused as it moves away from the LED (811).

[0331] The cultivation light (81) may include a lens (817) positioned below the cover (815). The lens (817) may be a convex lens.

[0332] This allows you to reduce the degree of light diffusion, direct the light vertically, or collect the light.

[0333] Through this, even if the distance between the lighting unit (80) and the cultivation unit (30) changes, the amount of light per unit area reaching the cultivation unit (30) can be maintained at a constant level.

[0334] The cultivation light (81) can be installed on the outer flange (861). The cultivation light (81) can be placed on the outer side of the outer flange (861).

[0335] The lighting unit (80) may include a mood light (82). The mood light (82) may be placed above the cultivation light (81).

[0338] The lighting unit (80) may include a hub (87) that supports the lampshade (84). The hub (87) may be positioned on the upper side of the flange (86).

[0339] The hub (87) may include a lower hub (876) positioned above the flange. The hub (87) may include an upper hub (871) positioned above the lower hub to support the lampshade (84).

[0340] A switch (85) may be provided in the lampshade (84). The switch (85) may be a touch switch. The upper hub (871) may accommodate a switch PCB connected to the switch (85).

[0341] The lighting unit (80) may include a diffuser plate (83) placed between the lampshade (84) and the mood light (82). The diffuser plate (83) can diffuse the light irradiated from the mood light (82).

[0342] The diffuser plate (83) can be in contact with the lampshade (84).

[0343] The diffuser plate (83) can be supported on the hub (87).

[0344] The mood light (82) may include a mood light PCB (823) arranged along the perimeter of a lampshade (84) or a diffuser plate (83), and a plurality of mood light emitting elements (821) installed on the mood light PCB (823) and arranged along the perimeter of the lampshade (84) or the diffuser plate (83). The mood light emitting elements (821) may be LEDs. Hereinafter, the mood light emitting elements (821) are referred to as mood light LEDs.

[0345] A plurality of mood light PCBs (823) can be arranged along the radial direction centered on the hub.

[0346] The mood light (82) may include a mood light base (829) on which a mood light PCB is placed. The mood light base may be tilted or stepped so that the central part is located on the upper side.

[0347] The mood light LED (821) can be positioned in the normal direction of the diffuser plate (83). For example, the mood light PCB can be positioned at an angle with respect to the vertical direction, and the mood light LED (821) can be positioned perpendicular to the mood light PCB.

[0348] The mood light LED (821) can be positioned horizontally. For example, the mood light PCB (823) can be positioned vertically, and the mood light LED can be positioned vertically relative to the mood light PCB.

[0349] A first wire (181) can be connected to the lighting unit (80). The first wire (181) can be connected to the lighting PCB (810) and the mood light PCB (823). The first wire (181) can be connected to the switch PCB (853).
