[0201]

[0202] Referring to FIG. 10, the height adjustment unit (60) may include a holder (68) coupled to the second pipe (62) and a friction unit (67) coupled to the holder (68). A detailed description of the holder (68) and the friction unit (67) will be provided later with reference to FIG. 11 to 13.

[0203] The height adjustment unit (60) may include a gas spring (64). The gas spring (64) may include a first coupling part (643) that is coupled to the base (10).

[0204] The plant cultivation device may include wires (181, 182) connecting the lighting unit (80) and the base (10). One end of the wires (181, 182) may be connected to the control unit (18), and the other end may be connected to the lighting unit (80).

[0205] The wires (181, 182) may include a first wire (181) connected to a lighting unit and a second wire connected to a control unit (18).

[0206] The second wire (182) can be extended in an upward and downward direction. The second wire (182) can be extended in a spiral shape. The second wire (182) can be extended in a spiral shape surrounding the gas spring (64).

[0207] The first wire (181) can pass through the holder (68). The holder (68) may have a hole through which the first wire (181) passes. The first wire (181) may extend upward along the second pipe (62).

[0208] When the second pipe (62) is extended upward, the vertical height of the second wire (182) can be increased due to the spiral structure of the second wire (182).

[0209] Accordingly, the lighting unit (80) can be connected to the control unit (18) by a wire even if the height at which it is placed is adjusted.

[0210]

[0211] Referring to FIGS. 10 and FIGS. 11, 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).

[0212] 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).

[0213] 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).

[0214] 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).

[0215] 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).

[0216] 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.

[0217] The inner circumferential surface (677) can surround the camshaft (687). The inner circumferential surface (677) can rotatably support the camshaft (687).

[0218] 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).

[0219] 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).

[0220] 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.

[0221] 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.

[0222] The holder (68) may include a spring coupling part (684). The spring coupling part (684) may be provided at the bottom of the holder (68).

[0223] The spring coupling portion (648) can protrude downward from the lower surface of the second disk (686).

[0224] The spring coupling part (684) can be coupled to the gas spring (64). The spring coupling part (684) can be coupled to the second coupling part (646) of the gas spring.

[0225]

[0226] Referring to FIG. 12, 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).

[0227] 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).

[0228] For example, the friction part (67) may be made of ABS (Acrylonitrile, Butadiene, Styrene) resin or polyacetal (POM, Polyoxymetylene).

[0229] The friction part (67) can be pressed into the hollow of the first pipe (61).

[0230] 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).

[0231] 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).

[0232] 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).

[0233] 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).

[0234] For example, the disc (685, 686) may be made of ABS (Acrylonitrile, Butadiene, Styrene) resin or polyacetal (POM, Polyoxymetylene).

[0235]

[0236] Referring to FIG. 13, 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. 13(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).

[0237] FIG. 13(b) shows that by rotating the holder (68) in FIG. 13(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. 13(c) shows that by rotating the holder (68) in FIG. 13(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).

[0238] 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).

[0239] 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.

[0240] 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.

[0241] 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.

[0242] Accordingly, if the disk (658, 686) or the second pipe (62) is rotated further clockwise in the state of Fig. 13(b), or if the disk (658, 686) or the second pipe (62) is rotated further counterclockwise in the state of Fig. 13(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.

[0243] Through this, the position of the second pipe (62) can be fixed relative to the first pipe (61).

[0244]

[0245] Referring to FIG. 14, 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).

[0246] The internal space of the cylinder (6441, 6442) is filled with compressed gas and may contain a small amount of oil.

[0247] 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.

[0248] 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.

[0249] 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.

[0250] 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.

[0251] 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).

[0252] The first coupling part (643) can be coupled to the base (10), and the second coupling part (646) can be coupled to the holder (68).

[0253] 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.

[0254] 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).

[0255]

[0256] Referring to FIGS. 15 and 16, the lighting unit (80) can be connected to the second pipe (62).

[0257] 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.

[0258] 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.

[0259] The light source (81) may include a cover (815). The cover (815) may include a hole (815) 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).

[0260] The cultivation light (81) may include a lens (817) positioned below the cover (815). The lens (817) may be a convex lens.

[0261] This allows you to reduce the degree of light diffusion, direct the light vertically, or collect the light.
