Description

Technical Field

[0001] This utility model relates to the field of ventilation tube technology, and in particular to a bottom ventilation tube for flower pots. Background Technology

[0002] With the improvement of people's living standards and the increase in gardening enthusiasts, flower cultivation has gradually become a fashionable and leisurely activity in modern life. As the basic infrastructure for flower cultivation, the design and function of flower pots directly affect the plant's growth environment and health. In flower pot design, breathability is a key factor, directly related to the respiration of plant roots, so breathable tubes are usually used.

[0003] However, the existing ventilation pipes have a simple structure and certain defects. For example, the upper end of the ventilation pipe is usually open to allow the plant roots to breathe and water. However, there are usually plants in the flower pot, and during the growth process, fallen leaves or dead insects will inevitably appear around the plant. Once these impurities and foreign objects enter the pipe, they will block the ventilation holes and thus affect the plant's respiration. Utility Model Content

[0004] The purpose of this invention is to provide a bottom ventilation tube for flower pots, which can effectively prevent fallen leaves, insects and other debris from entering the tube, thereby maintaining the unobstructed flow inside the tube.

[0010] According to the bottom venting pipe for a flowerpot, the fixing ring has a cavity inside, and the inner surface of the cavity is adapted to an L-shaped insert.

[0011] According to the bottom venting pipe for a flowerpot, the outer surface of the outer ring is provided with raised strips.

[0012] According to the aforementioned bottom ventilation pipe for a flowerpot, the upper end of the pipe body contacts the outer frame, and the number of handle blocks is four, arranged in a circular array.

[0013] According to the aforementioned bottom ventilation pipe for flower pots, the outer surface of the pipe body is fixedly connected to a fixing ring, and the outer surface of the L-shaped insert is slidably connected to the fixing ring.

[0014] According to the bottom ventilation tube for a flowerpot, the end of the arc-shaped slide rod is fixedly connected to the fixing ring, the stainless steel spring is sleeved on the outer surface of the arc-shaped slide rod, and the end of the stainless steel spring away from the L-shaped insert is fixedly connected to the fixing ring.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] 1. By setting up a filter screen, plant leaves, insects and other debris can be effectively prevented from entering the inside of the tube, thus maintaining the unobstructed flow inside the tube. In addition, by setting up a handle block, the tube can be prevented from being inserted too deeply into the soil and becoming difficult to pull out.

[0017] 2. By setting handle blocks, positioning blocks and limiting components, the entire filter screen can be installed and disassembled without the need for tools, making it highly practical.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4 This utility model provides a bottom ventilation tube for flower pots, comprising: a tube body 1, ventilation holes 2 on the outer surface of the tube body 1, an annular groove 3 at the upper end of the tube body 1 for easy installation of a filter screen 6, an annular block 4 movably connected to the inner surface of the annular groove 3, an outer frame 5 fixedly connected to the upper surface of the annular block 4, a filter screen 6 fixedly connected to the inner surface of the outer frame 5, a handle block 7 fixedly connected to the outer surface of the outer frame 5 for limiting the insertion of the tube body 1 into the soil and acting as a handle, a positioning block 8 fixedly connected to the lower surface of the handle block 7, a slot 15 on the outer surface of the positioning block 8, the upper end of the tube body 1 contacting the outer frame 5, and four handle blocks 7 arranged in a circular array.

[0028] The limiting component 9 includes a fixing ring 10, an outer ring 11, an L-shaped insert 12, an arc-shaped slide rod 13, and a stainless steel spring 14. The outer surface of the fixing ring 10 is rotatably connected to the outer ring 11, the inner surface of the outer ring 11 is fixedly connected to the L-shaped insert 12, the inner surface of the L-shaped insert 12 is slidably connected to the arc-shaped slide rod 13, the outer surface of the L-shaped insert 12 is fixedly connected to the stainless steel spring 14, and the inner surface of the slot 15 is adapted to the L-shaped insert 12 for easy overall fixation of the filter screen 6. The outer surface of the fixing ring 10 is designed with... A positioning hole 16 is provided, the inner surface of which is adapted to the positioning block 8, so as to facilitate the overall installation of the filter screen 6. The outer surface of the outer ring 11 is provided with a raised strip 18 to facilitate the rotation of the outer ring 11. The outer surface of the tube body 1 is fixedly connected to the fixing ring 10. The outer surface of the L-shaped insert 12 is slidably connected to the fixing ring 10. The end of the arc-shaped slide rod 13 is fixedly connected to the fixing ring 10. The stainless steel spring 14 is sleeved on the outer surface of the arc-shaped slide rod 13. The end of the stainless steel spring 14 away from the L-shaped insert 12 is fixedly connected to the fixing ring 10.

[0029] Working principle: During use, the tube 1 is inserted entirely into the soil inside the flowerpot, providing aeration to the plant roots through the ventilation holes 2. The handle 7 prevents the tube 1 from being inserted too deeply and also acts as a handle when the tube 1 is pulled out, thus improving the usability. During use, the filter 6 effectively prevents fallen leaves, insects, and other debris from entering the tube 1, maintaining its internal patency and preventing any impact on aeration. When the filter 6 needs to be replaced, simply rotate the outer ring 11, driving the L-shaped insert 12 along the curved slide bar 13. By sliding the stainless steel spring 14 and compressing it, the L-shaped insert 12 can be disengaged from the slot 15, thus releasing the limiting effect on the positioning block 8. Then, the entire filter screen 6 can be pulled out along the inside of the positioning hole 16 to complete the disassembly. Subsequently, the positioning block 8 on the new filter screen 6 is aligned with the positioning hole 16 and inserted. When the slot 15 on the positioning block 8 corresponds to the L-shaped insert 12, the retaining ring 10 is released. Under the rebound force of the stainless steel spring 14, the L-shaped insert 12 will automatically insert into the slot 15, thus completing the installation of the entire new filter screen 6. This process is simple, convenient, and practical, requiring no tools.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
