Technical Field

[0001] The present invention belongs to the technical field of plant cultivation, and in particular relates to a water-saving irrigation device and an irrigation method for planting plants. Background Art

[0002] A plant refers to a growing plant body including roots, stems, leaves and other parts. This word is usually used to describe a complete plant, including its various components. The plant as a whole can carry out photosynthesis. By utilizing light energy, chlorophyll and the catalytic action of enzymes, it converts water, inorganic salts and carbon dioxide into oxygen and organic matter, such as glucose, to supply the plant's own growth and development. Plant breeding is a broad field that includes the cultivation and management of various plants. Whether it is indoor potted plants or outdoor gardening, it is necessary to understand the basic needs of plants, such as light, water, soil and fertilizer, to ensure the healthy growth of plants. In addition, the plant cannot do without an appropriate amount of water during its growth process. Watering equipment can help maintain the appropriate humidity of the soil and promote the healthy growth of plants.

[0017] As a preferred embodiment of the present invention, through holes are provided on both the upper and lower sides of the fixing plate, and the through holes are used for outflow of water.

[0018] As a preferred embodiment of the present invention, the first step is to start the electric push rod by the user using the controller to make the electric push rod run, so that the operation of the electric push rod can drive the cross bar to move up and down, and the up and down movement of the cross bar can simultaneously use the fixed column to squeeze the surface of the adjustment groove to adjust the height of the second support frame and align it with the flower pot;

[0019] Step 2: After the adjustment is completed, the user inserts the humidity sensor into the inside of the flower pot again to sense the humidity of the soil inside the flower pot and obtain the amount of water that needs to be injected;

[0020] Step 3: The user injects water, and then uses the humidity sensor to set the water injection volume and cooperates with the control valve to inject the water into the interior of the flower pot;

[0021] Step 4: When the rod is inserted into the flowerpot, the soil can be used to squeeze the extrusion rod, so that the fixed plate moves upward on the surface of the rod, and at the same time drives the support block to pull the third spring upward, and then water is injected.

At this time, after the insertion rod moves out from the surface of the flower pot, the cleaning ring and the fixed plate can be rebounded by the rebound force of the first spring and the third spring, and the cleaning column and the cleaning ring are used to clean the humidity sensor and the soil at the bottom of the insertion rod respectively.

[0023] The beneficial effects of the invention are as follows:

[0024] 1. The new invention provides a first cleaning component, a soil inserting component, a second cleaning component, a limit groove, a limit rod, a third spring, a support block, a diverter plate and a through hole. By using the first cleaning component and the second cleaning component in combination, the soil adhered to the surface of the humidity sensor and the inside of the inserting rod can be cleaned. Then, by using the diverter plate and the through hole in combination, the water source can flow to different heights of the plant roots, making the water source more efficient. This is worthy of promotion. The irrigation device can be flexibly adjusted according to different crops and soil conditions, from extensive spraying to precise drip irrigation, thereby improving the utilization efficiency of water resources. Especially in areas with tight water resources, its water-saving effect is particularly significant.

[0025] 2. The present invention provides a first cleaning assembly.

[0026] 3. The present invention provides a soil-inserting assembly so that when the rod is inserted into the soil, water can flow into the interior of the flowerpot through the bottom of the rod to irrigate the roots of the plants.

[0027] 4. The present invention provides a second cleaning assembly. Through the use of the second cleaning assembly, when the insertion rod moves downward, the soil can be used to squeeze the extrusion rod, so that the extrusion rod is subjected to resistance and moves on the surface of the extrusion groove. After the insertion rod moves out, the extrusion rod can be bounced back by the rebound force of the third spring and the cleaning column can be used to clean the soil at the bottom of the insertion rod.

[0028] 5. The present invention provides a limit groove, a limit rod and a third spring, so that when the extrusion rod is subjected to soil resistance and moves on the surface of the extrusion groove, it can also drive the fixed plate to move. By setting the limit rod, the fixed plate can be more stable during the moving process.

[0029] 6. The present invention provides a support block, which can support the fixed plate when the fixed plate moves up and down through the cooperation of the support block and the limit rod.

[0030] 7. The present invention sets a diverter plate. When the water source falls on the surface of the diverter plate, it can flow out through the diverter plate, and can irrigate the plant roots at different heights. This avoids the traditional sprinkler irrigation method of increasing energy consumption to expand the area of ​​irrigation radiation, effectively reduces the energy consumption in the irrigation process, and has energy-saving effects.

[0031] 8. The present invention provides through holes so that the water source is first diverted by the diversion plate and then falls into the top of the fixed plate, flows down through the through holes, and irrigates the bottom of the roots of the plants. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Example 2

[0064] refer to Figures 1 to 6 The method includes the following steps: first, the user activates the electric push rod 81 by using a controller, so that the electric push rod 81 is in operation, so that the operation of the electric push rod 81 can drive the cross bar 82 to move up and down, and the up and down movement of the cross bar 82 can simultaneously use the fixed column 83 to squeeze the surface of the adjustment groove 11, thereby adjusting the height of the second support frame 2 and aligning it with the flower pot;

[0065] Step 2: After the adjustment is completed, the user inserts the humidity sensor 12 into the interior of the flower pot again to sense the humidity of the soil inside the flower pot and obtain the amount of water to be injected;

[0066] Step 3: The user injects water, and then uses the humidity sensor 12 to set the water injection amount, and cooperates with the control valve 6 to inject the water into the interior of the flower pot;

[0067] Step 4: When the insertion rod 141 is inserted into the flowerpot, the soil can be used to squeeze the extrusion rod 152, causing the fixed plate 153 to move upward on the surface of the insertion rod 141, and at the same time drive the support block 19 to pull the third spring 18 upward, and then water is injected. During the water injection process, the water source will first be diverted by the diverter plate 20, and the remaining water source will fall into the top of the fixed plate 153 and fall into the interior of the flowerpot from the surface of the through hole 21;

[0068] Step 5: After the water injection is completed, the second support frame 2 is driven by the controller to move upward, so that it simultaneously drives the insertion rod 141 to move out from the surface of the flower pot. At this time, after the insertion rod 141 moves out from the surface of the flower pot, the cleaning ring 131 and the fixed plate 153 can be rebounded by the rebound force of the first spring 132 and the third spring 18, and the cleaning column 154 and the cleaning ring 131 are used to clean the humidity sensor 12 and the soil at the bottom of the insertion rod 141 respectively.

[0069] Working principle of the present invention:

[0070] When in use, the user first uses the controller to start the electric push rod 81 to make the electric push rod 81 run. In this way, the operation of the electric push rod 81 can drive the cross bar 82 to move up and down. The up and down movement of the cross bar 82 can simultaneously use the fixed column 83 to squeeze the surface of the adjustment groove 11 to adjust the height of the second support frame 2 and align it with the flower pot. Then, when it is necessary to fill the flower pot with water, the user inserts the humidity sensor 12 into the interior of the flower pot to sense the humidity of the soil inside the flower pot and obtain the amount of water to be injected at the same time. When the insertion rod 141 is inserted into the flower pot, the soil can be used to squeeze the squeezing rod 152 at the same time, so that the fixed plate 153 moves upward on the surface of the insertion rod 141, and at the same time drives the support block 19 to pull the third spring 18 upward, and then water is injected. During the water injection process, the water source will first be diverted through the diverter plate 20, and then the remaining water source will fall into the top of the fixed plate 153 and fall into the interior of the flower pot from the surface of the through hole 21. The water source can flow out from the bottom of the insertion rod 141 and the surface of the diverter plate 20, so as to irrigate the roots of the plants at different heights.

[0071] After watering is completed, the controller drives the second support frame 2 to move upward, and at the same time drives the insertion rod 141 to move out from the surface of the flower pot. At this time, after the insertion rod 141 moves out from the surface of the flower pot, the cleaning ring 131 and the fixed plate 153 can be rebounded by the rebound force of the first spring 132 and the third spring 18, and the cleaning column 154 and the cleaning ring 131 are used to clean the humidity sensor 12 and the soil at the bottom of the insertion rod 141 respectively, so that it does not affect the next measurement value of the humidity sensor 12.

[0072] To sum up: this is a water-saving irrigation device and irrigation method for planting plants, by setting a first cleaning component 13, a soil insertion component 14, a second cleaning component 15, a limiting groove 16, a limiting rod 17, a third spring 18, a support block 19, a diverter plate 21 and a through hole 21. By using the first cleaning component and the second cleaning component in combination, the soil adhered to the surface of the humidity sensor and the inside of the insertion rod can be cleaned, and then through the use of the diverter plate and the through hole, the water source can flow to different heights of the roots of the plants, making the watering efficiency higher, and it is worthy of promotion.
