Detailed Implementation

[0043] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0044] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] See Figures 1 to 20 The hydroponic tube shown contains a liquid, such as a nutrient solution, for growing plants. The hydroponic tube includes a tube body, a front cap 15, and a rear cap 16, wherein:

[0046] The tube body includes a tube body 1 and a cap 2. Both the tube body 1 and the cap 2 are U-shaped. The cap 2 is snapped into the tube body 1, forming a space for containing liquid between the tube body 1 and the cap 2. When the tube body 1 and the cap 2 are snapped into place, both ends of the tube body (front end and rear end) are open. A front cap 15 and a rear cap 16 are respectively provided at the front and rear ends of the tube body to close the space. One of the front cap 15 and the rear cap 16 has a liquid inlet hole 1541 that communicates with the space. The liquid inlet hole 1541 is used to connect with an infusion pipeline to deliver liquid into the tube body through the infusion pipeline.

[0047] Both the tube body 1 and the cap 2 have a first end and a second end that are arranged opposite to each other. The first end and the second end of the tube body 1 (see...) Figure 5 (as indicated by a and b) extends along the length of the tube body 1. One of the first and second ends of the tube body 1 is provided with a snap-fit ​​portion extending axially along the tube body 1, and the other end is provided with a recessed portion 6 extending axially along the tube body 1. One of the first and second ends of the cover 2 is provided with a snap-fit ​​portion that mates with the recessed portion 6 on the tube body 1, and the other end is provided with a recessed portion 6 that mates with the snap-fit ​​portion on the tube body 1. By engaging the recessed portion 6 on the tube body 1 with the snap-fit ​​portion on the cover 2, and engaging the snap-fit ​​portion on the tube body 1 with the recessed portion 6 on the cover 2, the tube body 1 and the cover 2 can be quickly snapped together for assembly.

[0048] See Figure 2-7 The snap-fit ​​portion includes a first protrusion 3 and a second protrusion 4 disposed opposite to each other. The second protrusion 4 is closer to the receiving space of the tube body than the first protrusion 3, that is, the first protrusion 3 faces outward and the second protrusion 4 faces inward. The recessed portion 6 includes a first sidewall 61 and a second sidewall 62 disposed opposite to each other, and a connecting wall 63 connecting the first sidewall 61 and the second sidewall 62. The second sidewall 62 is closer to the receiving space of the tube body than the first sidewall 61, that is, the first sidewall 61 faces outward and the second sidewall 62 faces inward. The first protruding tooth 3 engages with the first sidewall 61, and the second protruding tooth 4 engages with the second sidewall 62. Both the first sidewall 61 and the first protruding tooth 3 have a protrusion 13 at one end. The inner side of the first sidewall 61 facing the second sidewall 62 and the side of the first protruding tooth 3 away from the second protruding tooth 4 have recesses 14. The protrusion 13 on the first sidewall 61 engages with the recess 14 on the first protruding tooth 3, and the recess 14 on the first sidewall 61 engages with the protrusion 13 on the first protruding tooth 3. That is, after assembly, the sides of the first sidewall 61 and the first protruding tooth 3 facing each other have recesses 14 that engage with the protrusion 13 on the other side. Self-locking is achieved through pushing, making it difficult for the pipe body 1 and the cover 2 to separate. Through tensile testing, it can withstand a lateral tensile force of 500N, preventing detachment caused by water flow impact.

[0049] In a preferred embodiment, both the end of the tube body 1 with the snap-fit ​​portion and the end of the cap 2 with the snap-fit ​​portion are provided with a third protruding tooth 5. The third protruding tooth 5 is located on the side of the second protruding tooth 4 away from the first protruding tooth 3, and a groove is formed between the third protruding tooth 5 and the second protruding tooth 4. The second sidewall 62 is engaged in the groove. Providing the third protruding tooth 5 increases the firmness of the snap-fit ​​between the tube body 1 and the cap 2, and at the same time prevents liquid in the tube body from flowing into the recessed portion 6.

[0050] In this example, the groove is V-shaped and the end of the second sidewall 62 is V-shaped, which facilitates the second sidewall 62 to be quickly and smoothly locked into the groove; the height of the third protrusion 5 is less than the height of the second protrusion 4, or the height of the third protrusion 5 is extended to cover most of the second sidewall 62, which better prevents liquid in the tube from flowing into the recess 6 and improves the tube life.

[0051] In some embodiments, the tube body 1 includes an outer tube layer 101 and an inner tube layer 102, with a first connecting portion 7 connecting the outer tube layer 101 and the inner tube layer 102. The outer tube layer 101 has a first end and a second end, and the inner tube layer 102 has a first end and a second end. The first end of the outer tube layer 101 corresponds to the first end of the inner tube layer 102, and the second end of the outer tube layer 101 corresponds to the second end of the inner tube layer 102.

[0052] The cover 2 includes an outer cover layer 201 and an inner cover layer 202, connected by a second connecting portion 8. The outer cover layer 201 has a first end and a second end, and the inner cover layer 202 also has a first end and a second end. The first end of the outer cover layer 201 corresponds to the first end of the inner cover layer 202, and the second end of the outer cover layer 201 corresponds to the second end of the inner cover layer 202. Both the first connecting portion 7 and the second connecting portion 8 extend axially along the tube body. (See attached image) Figure 2-7 The first connecting part 7 and the second connecting part 8 are provided with multiple parts. A gap is maintained between two adjacent first connecting parts 7 to form a hollow space, and a gap is maintained between two adjacent second connecting parts 8 to form a hollow space, which is conducive to ventilation, ensures support strength and reduces overall weight.

[0053] In a preferred embodiment, a first guide groove 9 is provided on the bottom wall of the inner tube layer 102, and the first guide groove 9 extends along the length direction of the tube body 1; a second guide groove 10 is provided on the top wall of the inner cover layer 202, and the second guide groove 10 extends along the length direction of the inner cover layer 202. When the cover 2 is placed on the tube body 1, the top wall of the inner cover layer 202 is located above the bottom wall of the inner tube layer 102, and the top wall of the inner cover layer 202 is opposite to the bottom wall of the inner tube layer 102. The second guide groove 10 on the top wall of the inner cover layer 202 is recessed upward, and the first guide groove 9 on the bottom wall of the inner tube layer 102 is recessed downward. The provision of the first guide groove 9 and the second guide groove 10 facilitates the flow of nutrient solution, reduces nutrient solution residue, and avoids blockage.

[0054] In this example, a pipe protective layer 11 is provided on the outer periphery of the pipe body 1; a cover protective layer 12 is provided on the outer periphery of the cover body 2. The overall structure is stable and the appearance is beautiful.

[0055] In this example, the pipe body is made of environmentally friendly food-grade PVC or PP material through extrusion molding. The thickness of the outer layer 101 ranges from 1 to 1.1 mm, and the thickness of the inner layer 102 ranges from 1.1 to 1.5 mm, combining lightweight and pressure resistance (pressure resistance ≥ 0.3 MPa).

[0056] In this example, the front cover 15 includes an upper cover and a lower cover disposed below the upper cover. The upper cover includes a first side plate 151 and a second side plate 152 disposed at one end of the first side plate 151. The first side plate 151 is U-shaped, and the second side plate 152 extends vertically. A groove for covering one end of the tube body 2 is formed between the first side plate 151 and the second side plate 152. The lower cover includes a U-shaped plate 153, a middle plate 154, and a connecting plate 155. The middle plate is disposed inside the U-shaped plate 153, and the connecting plate 155 connects the U-shaped plate 153 and the middle plate 154. A groove is formed between the U-shaped plate 153 and the middle plate 154, and one end of the tube body 1 is engaged in the groove. Preferably, the upper end face of the connecting plate 155 is positioned lower than the two ends of the U-shaped plate 153 and the upper end face of the middle plate 154, so that a U-shaped opening 156 is formed between one end of the U-shaped plate 153, one end of the connecting plate 155 and the upper end of the middle plate 154, and a U-shaped opening is formed between the other end of the U-shaped plate 153, the other end of the connecting plate 155 and the upper end of the middle plate 154. When assembled, the U-shaped opening is open to expose the part that is engaged with the recessed part 6, thereby improving the overall air permeability.

[0057] The rear cover 16 includes an upper cover and a lower cover disposed below the upper cover. The upper cover includes a first side plate 161 and a second side plate 162 disposed at one end of the first side plate 161. The first side plate 161 is U-shaped, and the second side plate 162 extends vertically. A groove for covering one end of the tube body 2 is formed between the first side plate 161 and the second side plate 162. The lower cover includes a U-shaped plate 163, a middle plate 164, and a connecting plate 165. The middle plate 164 is disposed inside the U-shaped plate 163, and the connecting plate 165 connects the U-shaped plate 163 and the middle plate 164. A groove is formed between the U-shaped plate and the middle plate 164, and one end of the tube body 1 is engaged in the groove. Preferably, the upper end face of the connecting plate 165 is positioned lower than the two ends of the U-shaped plate 164 and the upper end face of the middle plate 164, so that a U-shaped opening is formed between one end of the U-shaped plate 164, one end of the connecting plate 165 and the upper end of the middle plate 164, and a U-shaped opening is formed between the other end of the U-shaped plate 164, the other end of the connecting plate 165 and the upper end of the middle plate 164. When assembled, the U-shaped opening is open to expose the part that is engaged with the recessed part 6, thereby improving the overall air permeability.

[0058] Preferably, the inner wall of the second side plate is provided with a locking part 18 that cooperates with the hollow space on the cover 2, so that the upper cover and the cover 2 are more firmly connected. The locking part 18 also plays a guiding and positioning role, making operation more convenient.

[0059] The lower cover includes a U-shaped plate, a middle plate, and a connecting plate. The middle plate is disposed inside the U-shaped plate, and the connecting plate connects the U-shaped plate and the middle plate. A groove is formed between the U-shaped plate and the middle plate, and one end of the tube body 1 is engaged in the groove. Preferably, the upper end face of the connecting plate is positioned lower than the two ends of the U-shaped plate and the upper end face of the middle plate, so that a U-shaped opening is formed between one end of the U-shaped plate, one end of the connecting plate, and the upper end of the middle plate, and a U-shaped opening is formed between the other end of the U-shaped plate, the other end of the connecting plate, and the upper end of the middle plate. When assembled, the U-shaped opening is open, exposing the portion where the engaging part and the recessed part 6 are engaged, improving overall air permeability.

[0060] One of the middle plates of the lower cover of the front cover 15 or the lower cover of the rear cover 16 has an inlet hole to facilitate connection to the infusion pipeline.

[0061] In this example, the second side plate of the upper cover has a downwardly recessed arc-shaped opening. When both the upper and lower covers are located at one end of the tube, the middle plate of the lower cover is located at the arc-shaped opening, and the vertical end face of the second side plate and the vertical end face of the middle plate are located on the same vertical plane.

[0062] When there are multiple tubes, the hydroponic tube also includes an intermediate connector 17, which is used to connect two adjacent tubes, and the multiple tubes are distributed in a straight line.

[0063] See Figure 10-12 The intermediate connector 17 includes an outer annular sleeve 171, an inner annular sleeve 172, and a separating connecting part 173. The inner annular sleeve 172 is disposed inside the outer annular sleeve 171. The separating connecting part 173 is disposed in the lower part of the outer annular sleeve 171 and connected to the bottom of the inner annular sleeve 172. The upper part of the separating connecting part 173 and the upper part of the inner annular sleeve 172 are both separated from the upper part of the outer annular sleeve 171 to form a receiving space for accommodating one end of the cover 2. A first limiting groove is formed between one side of the inner annular sleeve 172 and one side of the outer annular sleeve 171 to limit one end of the tube body 1. A second limiting groove is formed between the other side of the inner annular sleeve 172 and the other side of the outer annular sleeve 171 to limit one end of the other tube body 1.

[0064] When two adjacent tubes are connected by the intermediate connector 17, one end of the tube body 1 of one tube abuts against the first limiting groove, and one end of the cover 2 of one tube is located in the receiving space; one end of the tube body 1 of the other tube abuts against the second limiting groove, and one end of the cover 2 of the other tube is located in the receiving space. The outer periphery of one end of the cover 2 abuts against the inner periphery of the outer annular sleeve 171, and the outer periphery of the tube body 1 abuts against the inner wall of the outer annular sleeve 171.

[0065] The specific implementation method for assembling the hydroponic tubes in this example is as follows:

[0066] Combine the tube body and the cap body of a tube. Assemble the lower cover of the front cap at one end of the assembled tube body, then place the upper cover of the front cap.
