One end of the water inlet pipe 45 penetrates the annular groove 43 and is connected to the annular water pipe 44. By setting the flower box 4 to be formed by welding of stainless steel plates, a accommodating cavity with an open top is formed in the flower box 4. By setting the partition plate 41, two independent cavities are formed inside the accommodating cavity. When cultivating ornamental flowers, they are cultivated in the cavity above the partition plate 41 in the flower box 4. By setting the water inlet pipe 45, the annular water pipe 44, and the water hole 441, when in use, water can be injected into the water inlet pipe 45 to allow the water to enter the annular water pipe 44, and then be discharged through multiple water holes 441 to water the ornamental flowers cultivated in the flower box 4, which is convenient for watering the ornamental flowers cultivated in the flower box 4; by setting the drainage hole 411, when it is rainy season or too much water is injected into the flower box 4, the water in the cavity above the partition plate 41 will flow downward through the drainage hole 411 to the cavity below the partition plate 41, and then be discharged to the external sewer through the drain pipe 42, so as to avoid water gathering in the cavity above the partition plate 41, thereby affecting the growth of the ornamental flowers.

[0040] Example 3

[0041] like Figures 1-4 As shown, based on the above embodiment, this embodiment further provides the following content:

[0042] In this embodiment, a drain valve 421 is fixedly installed on the drain pipe 42, and a liquid pump 1 46 is fixedly installed on the side of the flower box 4 close to the mounting frame 11. The liquid inlet end of the liquid pump 1 46 is connected to the bottom wall of the flower box 4, and the liquid outlet end is connected to the water inlet pipe 45. An overflow pipe 47 connected to the inside of the flower box 4 is fixedly installed on the side of the flower box 4 close to the mounting frame 11 and located below the partition plate 41. The overflow pipe 47 is connected to the external sewer pipe. A liquid pump 2 48 is fixedly installed on the side of the flower box 4 close to the mounting frame 11. The liquid pump 2 48 The liquid outlet is connected to the inside of the flower box 4, and the liquid inlet is connected to the external water source through a connecting pipe. The flower box 4 is provided with a mounting hole 49 on one side close to the mounting frame 11 and below the overflow pipe 47. A water level sensor 491 is fixedly installed on the flower box 4 and in the mounting hole 49. The model of the water level sensor 491 is MRLF100. The end of the water level sensor 491 extends into the flower box 4. Specifically, the water level sensor 491 is connected to the PLC control system, which is connected to the liquid pump 2 48 through the drain pipe 42. When in use, the drain valve 421 can be controlled to be closed to block the drain pipe 42, so that the water flowing downward through the drain hole 411 to the cavity below the partition plate 41 can be stored. When watering the ornamental flowers, the liquid pump 46 can be controlled to be opened. The liquid pump 46 can be operated to extract the water in the cavity below the partition plate 41 and transport it to the annular water pipe 44, and then discharged through the multiple water holes 441 to water the ornamental flowers cultivated in the flower box 4, thereby achieving the effect of water resource reuse. A water level sensor 491 and a liquid pump 48 are installed. The water level sensor 491 detects the water level of the water source stored in the cavity below the partition plate 41 in real time, and transmits the detection signal to the PLC control system. When the water level of the water source in the cavity below the partition plate 41 is lower than the position of the water level sensor 491, the detection signal is transmitted to the PLC control system, which controls the liquid pump 48 to open through the PLC control system to transport water to the cavity below the partition plate 41, thereby ensuring the water level of the water source stored in the cavity below the partition plate 41.

[0043] In this embodiment, a filter assembly 6 is fixedly installed in the flower box 4 and between the opposite sides of the partition plate 41 and the overflow pipe 47, which is used to filter the water source flowing downward through the drain hole 411. By setting the filter assembly 6, the water source flowing downward through the drain hole 411 can be filtered, thereby effectively preventing the water source in the cavity above the partition plate 41 from flowing downward through the drain hole 411, causing the soil for cultivating ornamental flowers to fall into the cavity below the partition plate 41 through the drain hole 411 and form mud in the cavity below the partition plate 41, thereby effectively avoiding the situation where the mud blocks the liquid pump 46 when the liquid pump 46 works to extract the water source in the cavity below the partition plate 41.

[0044] In this embodiment, the filter assembly 6 includes: a filter frame 61, a slot 62 connected to the interior of the flower box 4 is provided on the side of the flower box 4 away from the mounting frame 11 and between the partition plate 41 and the opposite side of the overflow pipe 47, the filter frame 61 is inserted into the flower box 4 along the slot 62 and blocks the interior of the flower box 4, a through hole 611 is provided on the filter frame 61 and below the multiple drain holes 411, a filter plate 63 is fixedly installed on the filter frame 61 and at the bottom position of the inner side wall of the through hole 611, and the filter plate 63 blocks the through hole 611. Specifically, it should be noted that the filter plate 63 has a side with the largest surface area, and the side with the largest surface area of the filter plate 63 blocks the through hole 611. The filter plate 63 A plurality of filter holes connected to the through-holes 611 are provided on one side with the largest surface area. When in use, the water source in the cavity above the partition plate 41 flows downward through the drain holes 411 and falls into the through-holes 611, thereby flowing downward through the filter holes on the filter plate 63 to the cavity below the partition plate 41. During this period, the filter plate 63 filters the soil for cultivating ornamental flowers, so that the soil for cultivating ornamental flowers remains on the top of the filter plate 63, thereby achieving a filtering effect on the water source flowing downward through the drain holes 411; by providing a slot 62, the filter plate 63 is inserted into the slot 62, thereby facilitating the installation or disassembly of the filter plate 63 and facilitating the cleaning of the residue remaining on the top of the filter plate 63.

[0045] In this embodiment, a fixing plate 7 is fixedly installed on one side of the filter frame 61. When the filter frame 61 is inserted into the slot 62, the fixing plate 7 fits against the flower box 4 and blocks the open end of the slot 62. A plurality of fixing plates 2 8 are fixed in a vertical array on the flower box 4 and above the slot 62. Specifically, it should be noted that the structure of the fixing plate 2 8 is the same as that of the fixing plate 7. The design of the fixing plate 7 facilitates the removal of the filter plate 63 from the slot 62, thereby further facilitating the disassembly of the filter plate 63.

[0046] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
