Description

Technical Field

[0001] This utility model relates to a device for assisting in the cultivation of plants, specifically a plant drip irrigation device. Background Technology

[0002] Plant drip irrigation systems are commonly used in horticulture and home gardening as a means of automatically watering or fertilizing potted plants. Traditional drip irrigation systems typically employ a combination of independent supports and a cylindrical tube. However, this design presents some inconveniences in practical applications, especially in outdoor settings. The independent support structure lacks sufficient stability after being inserted into the potting soil. Particularly when the system is filled with liquid, its center of gravity shifts upwards, making it more prone to tilting. This not only affects the accuracy of the dripping but can also negatively impact the growth of the potted plants. Furthermore, while the cylindrical tube design is simple, its volume is relatively small. This means that frequent replenishment of liquid is necessary during prolonged or heavy watering and fertilization, causing inconvenience for the user. Replenishing water becomes particularly difficult during transportation and handling. Utility Model Content

Detailed Implementation

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0032] As described in the background section, plant drip irrigation devices are commonly used in horticulture and home gardening as a type of automatic watering or fertilizing equipment for potted plants. Traditional drip irrigation devices typically employ a combination of independent supports and a cylindrical tube. However, this design presents some inconveniences in practical applications, especially in outdoor settings. The independent support of the drip irrigation device lacks sufficient stability after being inserted into the potting soil. Particularly when the device is filled with liquid, its center of gravity shifts upwards, making it more prone to misalignment. This not only affects the accuracy of the dripping but may also adversely impact the growth of the potted plants. Furthermore, while the cylindrical tube design of the drip irrigation device is simple, its volume is relatively small. This means that frequent replenishment of liquid is necessary during prolonged or heavy watering and fertilization, causing inconvenience to the user. Replenishing water is particularly difficult during transportation and handling.

[0033] For the reasons mentioned above, this embodiment provides a plant drip irrigation device, such as... Figures 1-7 As shown, it includes a housing 100 for containing liquid, which is a hemispherical shape with an opening at the top. A cover plate 200 is installed at the opening end. A liquid outlet pipe 300 is provided at the bottom of the housing 100, and a pull-out liquid outlet valve 400 is provided on the liquid outlet pipe 300.

[0034] The bottom of the housing has several support rods 500 arranged in a dispersed manner.

[0035] When using, such as Figure 9 As shown, the drip irrigation device is inserted into the pot 700 via a support rod. Liquid (water or nutrient solution) is filled into the hemispherical shell. The flow rate of the liquid dripping downwards is controlled by pulling the liquid outlet valve, thereby providing water or nutrient solution to the plants in the pot.

[0036] The aforementioned technical features enable the drip irrigation system to provide water or nutrient solution to potted plants. The design of the hemispherical shell and several support rods enhances the stability of the entire drip irrigation device, making it particularly suitable for outdoor potted plants or potted plants during transportation. It effectively prevents the drip irrigation device from tipping over or shifting due to external environmental factors, ensuring that the plants can continuously and stably obtain the water or nutrient solution they need.

[0037] To reduce the risk of blockage in the outlet pipe due to crystals or other impurities in the nutrient solution, in one embodiment, a filter screen 600 is placed inside the housing 100. The weight of the filter screen 600 is greater than the buoyancy of the liquid, which is water or nutrient solution. The filter screen not only effectively filters the liquid, reducing the risk of blockage in the outlet pipe at the lower end of the housing by impurities, but also ensures smooth operation of the drip irrigation device. Furthermore, the filter screen is made of stainless steel, which is not only corrosion-resistant and wear-resistant, but also automatically settles into a designated position on the housing according to gravity, achieving stable installation and further improving the reliability and durability of the drip irrigation device.

[0038] To limit the installation position of the filter screen, in one embodiment, a protrusion for placing the filter screen is provided on the inner wall of the housing. The protrusion serves to limit and support the filter screen.

[0039] To achieve flow control by pulling the outlet valve, in one embodiment, such as Figure 8 As shown, the discharge valve 400 includes a valve stem portion, which is radially mounted to the discharge pipe. A discharge hole 401 adapted to the discharge pipe is formed on the valve stem. A guide ridge 402 is formed on the valve stem, which matches a guide groove formed in the discharge pipe. The end of the valve stem is a grip portion 403.

[0040] The aforementioned technical features allow users to easily control the opening size of the outlet by pulling the valve stem, thereby adjusting the flow rate. Compared to traditional knob valves, the pull-out valve stem is not only easier to operate but also less prone to clogging. Even if clogging does occur, the convenient valve stem structure makes it easier to clear. Furthermore, the guide ridges on the valve stem match the guide grooves of the outlet pipe, ensuring smooth movement of the valve stem and effectively preventing rotation. This ensures a more precise match between the outlet and the outlet pipe, achieving stable flow control.

[0041] To facilitate the opening and closing of the cover, in one embodiment, such as Figure 7 As shown, the cover plate 200 is mounted to the housing 100 by a hinge, and a locking part 201 is installed on the edge of the cover plate; a protrusion 101 adapted to the locking part is provided on the housing; the cover plate and / or the housing have a transparent viewing part.

[0042] The aforementioned technical features enable quick closing of the cover. The cover engages with the protrusion to achieve a locking mechanism, preventing it from being easily opened during transport and thus preventing liquid spillage during bumps. The observation section allows users to easily monitor the amount of liquid inside the casing.

[0043] To further reduce liquid spillage from the housing due to bumps, in one embodiment, a sealing strip is provided between the cover plate that engages with the housing and the edge of the housing opening, and a vent valve is provided on the cover plate. The sealing strip reduces liquid spillage, while the vent valve ensures that the liquid drips smoothly downwards. The vent valve can be an existing waterproof vent valve to reduce liquid leakage from the vent valve.

[0044] To facilitate better insertion of the support rod into the potted plant, in one embodiment, the bottom of the support rod is tapered. This tapered design allows for easier insertion of the support rod into the potted plant, improving the stability of the drip irrigation device.

[0045] Meanwhile, the plant drip irrigation device described in this utility model is also suitable for small green belts in cities where large-scale drip irrigation is not possible, enabling drip irrigation of grass, shrubs, and trees; and the plant drip irrigation device is also suitable for scattered small plots of land on hillsides, because traditional irrigation in these areas involves manual water carrying, which is labor-intensive and requires many repetitions. With the drip irrigation of this device, drip irrigation pipes can be used, reducing the number of repetitions and labor intensity for workers, and also avoiding the problem of water waste in traditional manual irrigation.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
