Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, 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 protection scope of this utility model.

[0017] Example 1 The preferred embodiment of this utility model is a plant cultivation roller with adjustable drainage height, such as... Figure 1 As shown, see also Figures 2-4 The device includes a drum body 1 and multiple drain plugs 2. A through hole 10 is provided on the outer surface of the drum body 1, and a drain plug 2 is detachably connected to the through hole 10. A drain channel 20 is provided on the drain plug 2. After the drain plug 2 is installed at the through hole 10, the water inlet of the drain channel 20 extends beyond the through hole 10 and is spaced apart from the through hole 10 (this design ensures that the liquid level in the drum can only overflow when it exceeds the water inlet of the drain channel 20, thereby achieving the functions of ventilation and water storage). Different drain plugs 2 have different spacing (that is, multiple specifications of drain plugs 2 are defined, which is convenient for users to purchase and assemble as needed). The plant cultivation roller with adjustable drainage height of this application allows users to change the water storage height inside the roller by replacing the drainage plugs 2 with different drainage height sizes. When the water storage height inside the roller exceeds this value, the excess water will be discharged from the drainage hole 20, thereby achieving the purpose of automatically controlling the internal water level and ventilation. The overall structural design is extremely simple, with good effect and low cost. It should be noted that the multiple drain plugs 2 mentioned above in this application refer to multiple drain plugs 2 with different drainage height dimensions. In general, when using a plant, multiple drain plugs 2 with the same drainage height dimension will be selected and assembled with a roller body 1.

[0018] The specific installation structure of the drain plug 2 can adopt the following structure, or the structure as in Embodiment 2 and Embodiment 3, or other existing detachable structures. Such solutions obtained by simply replacing the existing disassembly and assembly structures also fall within the scope of protection of this application, and will not be listed here. The specific description is as follows: A deformable layer is provided on the outer surface of the drain plug 2 and / or the inner surface of the through hole 10, and the drain plug 2 and the through hole 10 are assembled by interference fit through the deformable layer; When the drain plug 2 is inserted into the through hole 10, the interference fit is achieved by extruding the deformable layer. The deformable layer can adopt the following structure, or it can be an attachment layer that is directly processed on the outer surface of the drain plug 2 and / or the inner surface of the through hole 10. Both can solve the problem of disassembly and assembly.

[0019] Preferably, the deformable layer is a waterproof ring 11 and is set on the inner wall of the through hole 10. At the same time, an annular positioning groove 21 that cooperates with the waterproof ring 11 is provided on the outer surface of the drain plug 2. This assembly structure can effectively solve the positioning problem during installation. After installation, the drain plug 2 has good consistency and beautiful appearance, which enhances the product's market competitiveness.

[0020] Preferably, a limiting flange 22 can be provided at the tail end of the drain plug 2. The limiting flange 22 is used to limit the assembly, which can improve the convenience of assembly.

[0021] Preferably, the front end of the drain plug 2 is provided with a groove 23 that communicates with the drain channel, and the rear end of the drain plug 2 is provided with a direction mark 24 that indicates the direction of the groove 23; this design can improve the air permeability and anti-clogging effect.

[0022] Preferably, multiple through holes 10 are provided, and the multiple through holes 10 are distributed in a ring around the axis of the roller body 1 on the outer surface of the roller body 1. This design is adopted to ensure that excess water can be discharged in time during the rotation process, and at the same time, it increases the ventilation holes. Preferably, multiple through holes are arranged obliquely or in a zigzag pattern on the roller body to balance the drainage and air permeability performance of the middle and both ends of the roller body.

[0023] Example 2 This embodiment is basically the same as the previous embodiment, and the similarities will not be repeated here. Figure 5 As shown, the difference is that: the outer surface of the drain plug 2 is provided with an external thread 25, and the inner wall of the through hole 10 is provided with an internal thread 12; a first sealing ring 26 is fitted on the drain plug 2 to seal against the roller body 1. This method uses a threaded connection installation design. During installation, it is tightened and sealed by the first sealing ring 26.

[0024] Example 3 This embodiment is basically the same as the previous embodiment, and the similarities will not be repeated here. Figure 6As shown, the difference is that: the outer surface of the drain plug 2 is provided with an L-shaped groove 27, and the inner wall of the through hole 10 is provided with a locking block 13 that cooperates with the groove 27; a second sealing ring 28 is fitted on the drain plug 2 to seal against the roller body 1. This method uses a snap-fit ​​connection installation design. During installation, align the snap-fit ​​13 with the longitudinal edge of the slot 27, push the drain plug 2 into the through hole 10 until the second sealing ring 28 deforms, at which point the snap-fit ​​block 13 reaches the lateral edge of the slot 27, and rotate the drain plug 2 to snap the snap-fit ​​block 13 into place.

[0025] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
