[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0045] The present application aims to provide a plant watering and curing device which can make plants obtain water in the air and reduce the difficulty of plant watering and curing.

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be described in further detail below with reference to the drawings and specific embodiments.

[0047] Embodiment one

[0048] The present embodiment provides a plant watering and curing device, please refer to Figures 1-5 , comprising a water collecting unit 1 and a water delivery unit 2, wherein the water collecting unit 1 is connected with the external environment, the water collecting unit 1 comprises a semiconductor refrigeration sheet 101, the semiconductor refrigeration sheet 101 can condense water vapor in the water collecting unit 1 to obtain condensate water;The water delivery unit 2 is connected with the water collecting unit 1, the water delivery unit 2 comprises a water delivery rod 201, the water delivery rod 201 can be inserted into the soil where the plant root is located, the water delivery rod 201 is connected with the water collecting unit 1 in communication, so that the condensate water flows into the water delivery rod 201, and the water delivery rod 201 has a water-permeable hole 202, so as to deliver the condensate water to the soil where the plant root is located.

[0049] The semiconductor refrigeration sheet 101 of the water collecting unit 1 can condense water vapor in the air, so that the water collecting unit 1 can obtain condensed water smoothly, the water conveying plug rod 201 is communicated with the water collecting unit 1, so that the condensed water can be conveyed into the water conveying plug rod 201 smoothly, and then the condensed water can permeate into the soil where the plant roots are located through the water permeable holes 202 of the water conveying plug rod 201, so that the plant watering and maintenance are realized. There is water in the air, and the atmosphere where human beings live is also a water vapor circulation circle. According to different air temperature, humidity and atmospheric pressure, the water content in the air is also different. Even in the extremely dry desert area, there is still a small amount of water in the air. Therefore, the utility model obtains fresh water from the air, and uses the fresh water for plant watering and maintenance, so that the operation convenience of the plant watering and maintenance is improved, especially in the area without water supply network, the difficulty of the plant watering and maintenance is reduced.

[0050] Specifically, the water collecting unit 1 further comprises a solar cell panel 102, the solar cell panel 102 is electrically connected with the semiconductor refrigeration sheet 101, and the solar cell panel 102 provides a power source for the semiconductor refrigeration sheet 101. The solar cell panel 102 converts solar energy into electric energy, and the clean energy is pollution-free and sustainable. In order to avoid the influence of the solar cell panel 102 on the refrigeration of the semiconductor refrigeration sheet 101, a heat-conducting back plate 103 is arranged on the side of the solar cell panel 102 close to the semiconductor refrigeration sheet 101, so as to further ensure the working reliability of the water collecting unit 1.

[0051] In actual application, the solar cell panel 102 can adopt cadmium telluride or perovskite solar cell. The cadmium telluride and perovskite solar cell have a wide spectral absorption range, so they have good weak light performance. The use of cadmium telluride or perovskite solar cell can improve the water collecting efficiency of the water collecting unit 1 in a weak light environment.

[0052] It should be further pointed out that, in actual application, a hydrophobic structure layer can be arranged on the cold surface of the semiconductor refrigeration sheet 101, so as to avoid the formation of a water film on the surface of the semiconductor refrigeration sheet 101, avoid affecting the water collecting efficiency of the semiconductor refrigeration sheet 101, and ensure the normal work of the semiconductor refrigeration sheet 101. The edge of the heat-conducting back plate 103 is provided with a heat-conducting mounting edge, so as to further improve the heat conduction efficiency of the heat-conducting back plate 103. The heat-conducting mounting edge can be fixed by using heat-conducting silicone. The heat-conducting mounting edge is arranged, so that the water collecting unit 1 can be attached to the heat-dissipating support through the heat-conducting silicone. At the same time, the heat of the hot surface of the semiconductor refrigeration sheet 101 and the heat of the solar cell panel 102 can be conducted to the heat-dissipating support and other structures with lower temperature through the heat-conducting mounting edge for heat dissipation. The holes on the heat-dissipating support can play the role of gas exchange and heat dissipation.

[0053] The solar panel 102 provides electricity for the semiconductor refrigeration sheet 101 arranged on the heat-conducting back plate 103. According to the Peltier effect, the cold face of the semiconductor refrigeration sheet 101 transfers heat to the hot face after being electrified, and the temperature of the cold face decreases. The water vapor in the air near the cold face condenses on the surface in the form of condensed water or frost. The cold face of the semiconductor refrigeration sheet 101 is provided with a hydrophobic coating. In the condensed water working condition, the hydrophobic coating prevents the formation of a water film on the surface of the cold face of the semiconductor refrigeration sheet 101, reduces the influence of the water film on heat conduction, and improves the air water extraction efficiency.

[0054] In the specific embodiment, the water supply unit 2 further comprises a support plug rod 208 and a water supply conduit 209. The support plug rod 208 can be inserted into the soil where the plant roots are located to provide stable support for the water collection unit 1. The water supply plug rod 201 is connected to the water collection unit 1 through the water supply conduit 209. The water supply conduit 209 is used to transport condensed water into the water supply plug rod 201 and then to the soil where the plant roots are located.

[0055] In practical applications, the water collection unit 1 can be arranged in multiple groups. The water collection unit 1 can be arranged in a flat plate or an arc-shaped plate structure. The shape of the water collection unit 1 can be selected according to the actual working conditions. Multiple water collection units 1 can be connected in a detachable manner to form various shapes that meet the requirements of the use environment, such as columnar, spherical, irregular, and other structures. The modular structure can be assembled, which greatly improves the flexibility and adaptability of the plant watering and maintenance device.

[0056] More specifically, the water collecting unit 1 can be fixed by using the heat dissipation support, adjacent water collecting units 1 can be connected by using the heat dissipation support, the support insertion rod 208 is connected with the heat dissipation support, so that the support insertion rod 208 can provide support for the water collecting unit 1, and the overall stability of the device is improved. Wherein, the heat dissipation support comprises a collecting bucket 203, a mounting column 204 and a cover plate 205, the collecting bucket 203 is a top opening structure with gradually decreasing cross-sectional area, which is convenient for collecting condensed water, and the collecting bucket 203 is connected with the water conveying pipe 209, so that the condensed water can be smoothly conveyed to the water conveying pipe 209, and then conveyed to the water conveying insertion rod 201, and finally permeated into the soil of the plant roots. A plurality of mounting columns 204 are connected with the top of the side wall of the collecting bucket 203 and are evenly distributed along the axis of the collecting bucket 203, and a semiconductor refrigeration sheet 101 is arranged between every two adjacent mounting columns 204, which provides stable support for the semiconductor refrigeration sheet 101. In this specific embodiment, a plurality of water collecting units 1 are arranged, the columnar structure surrounded by the mounting column 204 and the water collecting unit 1 is connected with the collecting bucket 203, so that the condensed water can smoothly enter the collecting bucket 203 under the action of gravity, and the cover plate 205 is arranged on the top of the mounting column 204 and the water collecting unit 1, and the cover plate 205 is detachably connected with the mounting column 204, which is convenient for disassembly and maintenance. The mounting column 204 and the cover plate 205 are provided with a plurality of heat dissipation holes 206, so that external air can smoothly enter the inside of the water collecting unit 1, and then the condensed water can be obtained. At the same time, the heat dissipation holes 206 can also play a heat dissipation role, and the heat exchange and heat dissipation between the external air of the water collecting unit 1 and the heat generated by the water collecting unit 1 are realized through the heat dissipation holes 206, so as to ensure the normal operation of the water collecting unit 1.

[0057] It should be further pointed out here that the collecting bucket 203 is a funnel structure, or other top opening structure with gradually decreasing cross-sectional area, so that the collecting bucket 203 has the function of storing water, so as to meet the requirements of condensed water collection and conveying. The low-temperature condensed water stored in the collecting bucket 203 can play a role in cooling the water collecting unit 1 due to the low temperature and high specific heat capacity of water. In order to further improve the heat conduction efficiency, the heat dissipation support can be made of metal material.

[0058] In other specific embodiments of the present application, the water conveying pipe 209 is threadedly connected with the collecting bucket 203, the connection is fastened, and the two are convenient to disassemble and assemble, and a sealing element is arranged between the two to avoid leakage. In other specific embodiments of the present application, the water conveying pipe 209 can be selected as a hose, which is convenient for conveying condensed water and can be bent at will to ensure that the condensed water is conveyed to the soil of the plant roots to water and maintain the plant. When the water conveying pipe 209 is selected as a hose, it can be connected with the collecting bucket 203 by plug-in connection. Correspondingly, the support insertion rod 208 is threadedly connected with the collecting bucket 203, the connection is fastened, and the two are convenient to disassemble and assemble.

[0059] In order to avoid the blockage of the water delivery pipe 209, a filter element 207 is arranged at the communication position of the water delivery pipe 209 and the water collecting unit 1, which effectively intercepts foreign matters and avoids the blockage of the water delivery pipe 209 caused by the foreign matters, thereby ensuring the smooth delivery of the condensed water to the soil of the plant roots.

[0060] Further, the water delivery rod 201 has an inverted conical tip, and a plurality of water permeable holes 202 are arranged on the sidewall of the water delivery rod 201. The water delivery pipe 209 can deliver the condensed water to the soil surface where the plant roots are located, and the water permeates to the plant roots to provide water for the plant. In use, the water delivery rod 201 is inserted into the soil of the plant roots, so that the water is directly delivered to the inside of the soil where the plant roots are located, thereby reducing the evaporation of the water. The water delivery pipe 209 delivers the condensed water to the water delivery rod 201, and the water slowly permeates to the soil of the plant roots through the water permeable holes 202 of the water delivery rod 201. It should be further noted that the bottom end of the water delivery rod 201 is an inverted conical tip, which facilitates the insertion of the water delivery pipe 209 into the soil. Correspondingly, the bottom of the supporting rod 208 can also be arranged as an inverted cone, thereby improving the operation convenience of the device.

[0061] In order to improve the uniformity of the water permeability of the water delivery rod 201, the water permeable holes 202 are arranged in multiple groups, and the multiple groups of water permeable holes 202 are circumferentially and uniformly distributed around the axis of the water delivery rod 201. The number of water permeable holes 202 in each group is multiple, and each group of water permeable holes 202 is uniformly distributed at equal intervals along the axial direction of the water delivery rod 201, so that the liquid water collected by the water collecting unit 1 is uniformly permeated into the soil. Even if some of the water permeable holes 202 are blocked, it will not affect the normal use of other water permeable holes 202.

[0062] In order to further improve the structural stability of the water delivery pipe 209, a plurality of pipe clamps 210 are arranged on the supporting rod 208, and the pipe clamps 210 can fix the water delivery pipe 209. The pipe clamps 210 are U-shaped structures, the openings of the pipe clamps 210 are arranged towards the side away from the supporting rod 208, the pipe clamps 210 are arranged along the vertical direction of the supporting rod 208, and the pipe clamps 210 are used to fix the end of the water delivery pipe 209 close to the water collecting unit 1. This can avoid the swinging of the water delivery pipe 209 caused by the wind, thereby affecting the service life of the water delivery pipe 209. At the same time, it can also prevent the disconnection of the water delivery pipe 209, thereby improving the water delivery reliability of the water delivery pipe 209 and the aesthetics of the device.

[0066] The plant watering and maintaining device can be used for watering and maintaining balcony potted plants, and comprises a water collecting unit 1 and a water conveying unit 2. The water collecting unit 1 comprises a semiconductor refrigeration sheet 101, a heat-conducting back plate 103 and a heat-dissipating protective cover 104. The heat-dissipating protective cover 104 has a plurality of heat-dissipating holes 107. The heat-conducting back plate 103 and the semiconductor refrigeration sheet 101 are arranged in an inner cavity of the heat-dissipating protective cover 104. The heat-conducting back plate 103 is connected with an inner wall of the heat-dissipating protective cover 104.

The water conveying rod 201 can be inserted into potted soil. The water conveying rod 201 has water-permeable holes 202.

[0067] In the embodiment, the heat-dissipating protective cover 104 is in a cylindrical structure. The heat-conducting back plate 103 is arranged parallel to the axis of the heat-dissipating protective cover 104 and divides the heat-dissipating protective cover 104 into two half cylinders to enhance the heat-dissipating effect. In actual application, the heat-dissipating protective cover 104 and the heat-conducting back plate 103 can be formed as an integral piece. A hole plate can be used to form a structure similar to S in cross section. The heat-conducting back plate 103 is arranged in the heat-dissipating protective cover 104 to improve the structural strength of the water collecting unit 1.

[0068] In order to improve the water efficiency, the two sides of the heat-conducting back plate 103 are provided with semiconductor refrigerating sheets 101, so that the water collecting unit 1 can supply sufficient water for the potted plants. The heat-conducting back plate 103 and the semiconductor refrigerating sheets 101 are connected by heat-conducting silica gel, which improves the overall structural integrity and ensures that the semiconductor refrigerating sheets 101 can be cooled smoothly, thereby improving the working reliability of the semiconductor refrigerating sheets 101.

[0069] Specifically, the bottom of the heat-dissipating protective cover 104 is connected with a collecting hopper 203, which has a funnel structure. The larger-diameter end of the collecting hopper 203 is connected with the heat-dissipating protective cover 104, and the smaller-diameter end of the collecting hopper 203 is connected with the water delivery plug 201, so as to deliver the condensed water into the water delivery plug 201. The collecting hopper 203 collects the liquid water condensed by the semiconductor refrigerating sheets 101 from the water vapor in the air. The funnel structure of the collecting hopper 203 ensures that the condensed water can be smoothly delivered into the water delivery plug 201.

[0070] In order to facilitate the cleaning and maintenance of the water delivery plug 201, the water delivery plug 201 is threadedly connected with the collecting hopper 203. The connection is fastened and disassembled conveniently, and a sealing thread can be used to prevent leakage of condensed water. In actual application, multiple groups of water delivery plugs 201 with different specifications can be provided.

Different water delivery plugs 201 can be replaced according to the watering and maintenance requirements of the potted plants, so as to adapt to the watering and maintenance requirements of different potted plants and improve the flexible adaptability of the device.

[0071] More specifically, the water delivery plug 201 includes a water storage part, a water-permeable part, and an insertion part connected in sequence from top to bottom. The water storage part is connected with the collecting hopper 203, the water-permeable holes 202 are arranged on the side wall of the water-permeable part, and the insertion part has an inverted conical structure. The water delivery plug 201 is provided with the water storage part to store condensed water. After the condensed water enters the water delivery plug 201, it is mixed with the normal-temperature condensed water stored in the water storage part, and then flows into the water-permeable part and penetrates into the soil of the potted plant roots to water and maintain the plant, thereby avoiding the direct flow of low-temperature condensed water to the plant roots to cause frost damage. In addition, the bottom of the water delivery plug 201 is provided with an inverted conical insertion part, which improves the operation convenience of the water delivery plug 201 inserted into the soil.
