Description

TECHNICAL FIELD

[0001] The present application relates to the field of plant maintenance and flower preservation, and particularly relates to a self-powered in-situ hydrogen production plant maintenance device, which is especially suitable for fresh-cut flower preservation and potted plant growth promotion. BACKGROUND

[0002] In recent years, hydrogen molecules (H2) as a new type of bioactive gas have gradually attracted attention in the field of plant maintenance. Studies have shown that hydrogen has a significant antioxidant effect on plants, which can effectively delay the aging process of fresh-cut flowers and prolong their vase life. At the same time, hydrogen has also been found to act as a gas signal molecule involved in the regulation of plant physiological metabolism, promoting the growth of potted plants.

[0003] However, despite the promising application prospects of hydrogen in agriculture and horticulture, it still faces significant technical bottlenecks in practical operation. Currently, the main methods to achieve hydrogen supply rely on external hydrogen cylinders, chemical hydrogen agents, or ex-situ electrolytic hydrogen-rich water generators. These methods generally have the following problems: large equipment size, complex operation process, safety hazards of hydrogen storage and transportation, and low utilization rate of prepared hydrogen, with most of it escaping into the atmosphere during transfer, making it difficult to effectively and conveniently integrate with daily-use flower vases, flower pots, and other containers. This makes it difficult for existing technologies to form an independent, simple, and easy-to-maintain solution in ordinary user scenarios such as homes and offices. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a self-powered in-situ hydrogen production plant maintenance device, which highly integrates hydrogen production functions inside the plant container, realizes in-situ generation and on-demand supply of hydrogen, and thus provides a truly easy-to-use and efficient hydrogen plant maintenance tool for users.

[0005] The purpose of the present application is achieved by the following technical solutions: A self-powered in-situ hydrogen production plant maintenance device, comprising: a container body for containing liquid and supporting plants; an in-situ hydrogen production module arranged in the liquid cavity of the container body, which generates hydrogen by electrolyzing water; the in-situ hydrogen production module is provided with a hydrogen output end and an oxygen output end, the hydrogen output end is in communication with the liquid cavity of the container body, and the oxygen output end is in communication with the atmosphere; an energy supply module for providing electrical energy for the device; an energy storage module electrically connected to the energy supply module and the hydrogen production module, for storing electrical energy and supplying electrical energy to the in-situ hydrogen production module.

[0006] Furthermore, the container body is a vase, and the in-situ hydrogen production module is located at the bottom or side wall of the vase, with its hydrogen output end in direct contact with the water in the inner cavity of the vase.

[0007] Furthermore, the container body is a flowerpot, comprising: The outer shell of a container used to hold water; A basin, placed on top of the outer shell of the container, is used to hold the planting medium and plants; the bottom of the basin has multiple ventilation holes; A water-guiding structure is provided between the pot body and the outer shell of the container, for guiding the water inside the outer shell of the container to the planting medium in the pot body; The in-situ hydrogen production module is located in the liquid cavity of the container shell. The hydrogen it produces dissolves in the water in the container shell and diffuses into the planting medium of the pot through the water-guiding structure and the air vents at the bottom of the pot.

[0008] Furthermore, the energy supply module is any one or more of a solar panel, a wired charging interface, and a wireless charging receiving coil.

[0009] Furthermore, the water-guiding structure is an absorbent rope, an absorbent cotton core, or a capillary assembly.

[0010] Furthermore, the in-situ hydrogen production module includes a hydrogen production module shell, and a protective filter layer, a cathode plate, a proton exchange membrane, and an anode plate arranged sequentially from top to bottom inside the hydrogen production module shell.

[0011] Furthermore, the protective filter layer is a porous fiber material.

[0012] Furthermore, the protective filter layer is filter paper, non-woven fabric, or cotton.

[0013] Furthermore, the device is configured to maintain the dissolved hydrogen concentration in the liquid inside the container body within the range of 0.05 ppm to 1.5 ppm.

[0014] The beneficial effects of this invention are as follows: (1) The plant care device of the present invention is an in-situ hydrogen production device. The hydrogen production module can be directly built into the bottom or side wall of the container. The structure is compact and realizes the immediate production and use of hydrogen. It avoids the problems of low efficiency, long time and safety risks caused by making hydrogen-rich water. The microbubbles generated by in-situ hydrogen production have a long residence time in the water, which maximizes the utilization efficiency of hydrogen and can effectively maintain the hydrogen concentration in the water. By maintaining a stable low-concentration hydrogen-rich environment, the antioxidant capacity of hydrogen can be used to effectively extend the freshness of flowers, or the regulatory effect of hydrogen can be used to promote the growth and flowering period regulation of potted plants.

[0015] (2) The plant care device of the present invention, through the energy supply module and the energy storage module, enables the device to adapt to various indoor and outdoor use scenarios, thereby improving the universality of the plant care device and the user experience.

[0016] (3) Using the plant care device of the present invention, no chemical agents need to be added during the plant care process, thus avoiding potential safety and environmental risks. Attached Figure Description

The energy supply module 3 provides electrical energy to the entire device; the energy storage module 4 is electrically connected to both the energy supply module 3 and the hydrogen production module, storing electrical energy and supplying power to the in-situ hydrogen production module 2.

[0025] like Figure 2 As shown, the in-situ hydrogen production module 2 includes a hydrogen production module housing 205, and a protective filter layer 201, a cathode plate 202, a proton exchange membrane 203, and an anode plate 204 arranged sequentially from top to bottom inside the hydrogen production module housing 205. The protective filter layer 201 is a porous fibrous material such as filter paper, non-woven fabric, or cotton, used to block solid impurities.

[0026] The energy supply module 3 can be one or more of the following: a solar panel, a wired charging interface, or a wireless charging receiver coil.

[0027] The energy storage module 4 provides DC voltage to the in-situ hydrogen production module 2, driving it to electrolyze water. The hydrogen generated at the cathode is directly dissolved into the container body 1, forming a hydrogen-rich water environment. The antioxidant effect of hydrogen helps plants to be better cared for.

[0028] Example 1: Self-Powered In-Situ Hydrogen Generation Vase Device like Figure 3 As shown, in this embodiment, the container body 1 is a 2L plastic vase used to hold water and fresh flowers. The in-situ hydrogen production module 2 is fixed to the bottom of the plastic vase, and the hydrogen output end of the in-situ hydrogen production module 2 is connected to the inner cavity of the plastic vase, while the oxygen output end of the in-situ hydrogen production module 2 is connected to the atmosphere outside the bottle. The energy supply module 3 is a 5W perovskite solar panel used to convert solar energy into electrical energy. The energy storage module 4 is a 1000 mWh lithium battery pack, which is connected to the energy supply module 3 and the in-situ hydrogen production module 2 respectively. The energy supply module 3 stores electrical energy to power the hydrogen production module 2. The protective filter layer 201 is filter paper, the cathode plate 202 is platinum-plated titanium foam, and the anode plate 204 is iridium-plated titanium mesh.

[0029] use Figure 3 The self-powered in-situ hydrogen-generating vase shown was filled with tap water and commercially available cut roses, and placed on a balcony. Under sufficient sunlight during the day, visible bubbles were observed forming on the hydrogen-generating module. A regular vase was used as a comparison, also filled with tap water and commercially available roses. The condition of the roses was recorded after 9 days; the comparison results are shown below. Figure 4The results show that the self-powered in-situ hydrogen-generating vase device of this embodiment can effectively extend the vase life of roses.

[0030] Example 2: Self-Powered In-Situ Hydrogen Generation Flowerpot Device like Figure 5 As shown, this embodiment is a self-powered in-situ hydrogen production flowerpot device, wherein the container body 1 includes an outer shell 101, a pot body 102 and a water-conducting structure 103.

A 5V DC power supply is used to charge the lithium battery for 2 hours via the energy supply module 3. The stored energy in the lithium battery can continuously produce hydrogen for the in-situ hydrogen production module 2 for 24 hours. Before the clivia blooms in spring, charging is initiated. The hydrogen produced by the in-situ hydrogen production module 2 dissolves in the water and, through the water intake structure 103 and the openings in the pot 102, acts on the clivia's root system, soil, and leaves, promoting earlier flowering by 7-14 days, thus achieving flowering period regulation.
