[0002] During plant cultivation, regular irrigation is necessary to ensure that the plants have sufficient water for growth. Plant irrigation requirements vary depending on the plant species, planting environment, and planting method. Currently, the main irrigation methods include flooding, sprinkler irrigation, and micro-irrigation. When irrigating, choose the appropriate method based on the plant's habits and planting environment.

[0003] The existing utility model patent with authorization announcement number CN207613021U discloses an automatic intelligent irrigation unit, including a water pump, a filter tube at the bottom of the water pump, a stirring chamber on one side of the water pump, a liquid level sensor on one side of the inner wall of the stirring chamber, and a pH sensor at the bottom of the inner wall of the stirring chamber;

[0004] There is also a utility model patent with authorization announcement number CN215380464U, which discloses an automatic intelligent irrigation unit. The upper side of the water tank is connected to a metering valve pipe, and the end of the metering valve pipe away from the water tank is connected to a medicine storage tank. A stirring mechanism is provided in the water tank, and a water outlet is connected to the bottom of one side of the water tank. The water inlet end of the water pump is connected to the water outlet, and the water outlet end of the water pump is connected to a water guide hose.

[0005] For example, in the two technical solutions mentioned above, one adopts the method of laying a watering net for farmland irrigation, and the other adopts an adjustable irrigation structure that drives the water supply pipeline to move by a screw mechanism; both of the above solutions require a large amount of water and cannot accurately control the water demand of the plants; especially for indoor planting, if the plants are planted in a culture tray, or the plants are potted plants, the first solution is limited by the water supply method of supplying water from the water supply end to the end, and the plants close to the water supply mechanism will be watered more, while the plants at the end will be watered less.

[0049] In another aspect, the present invention provides a method for using the multi-channel water-fertilizer integrated irrigation unit as described above, comprising the following steps:

[0050] S1. Cut off the passage between the tee pipe and the air compressor unit through the switch valve;

[0051] S2, water is fed into the telescopic pipe of the mixing assembly through the water supply unit, and the water flows into the sliding pipe through the one-way valve.

[0052] S3, supply medicine or fertilizer into the sliding tube through the first adding tube,

[0053] S4. The motor of the stirring assembly drives the stirring roller to rotate to mix the water flow and the medicine or fertilizer, and simultaneously clean the inner wall of the middle tube.

[0054] S5, water flows through the outlet trough into the irrigation pipe and flows out through the through hole, thereby achieving irrigation;

[0055] During irrigation, the water flow is increased to push the telescopic tube to stretch, thereby driving the sliding tube to correspond to different through holes, or the sliding tube is driven to move by pulling the cable;

[0056] Among them, at the end of irrigation, the passage between the three-way pipe and the water supply unit is cut off by the switch valve, and then the air compressor unit performs suction, forming negative pressure in the telescopic pipe, driving the sliding pipe to move back and reset.

[0057] The multi-channel integrated water and fertilizer irrigation unit and its application method of the present invention have the following beneficial effects compared with the prior art:

[0058] (1) By setting up a water supply unit, it can deliver water to the mixing component. The irrigation pipeline is provided with a plurality of through holes, so the through holes can be matched to the plant culture tray. In addition to supplying irrigation water, the water supply unit also controls the displacement of the mixing component, so that the matching of the mixing component and the through holes can be achieved, thereby achieving precise irrigation of plants, making full use of water resources and reducing waste; after the irrigation is completed, the air compressor unit generates negative pressure to drive the mixing component to reset; at the same time, the mixing component can be supplied with drugs or fertilizers by adding components to mix the water flow, thereby preventing and controlling plant diseases and supplying nutrients;

[0059] (2) The mixed delivery component is provided with a telescopic tube and a sliding tube. When water is supplied into the telescopic tube, as the water pressure increases, the telescopic tube will extend, thereby driving the sliding tube to move. Then, the water outlet of the sliding tube will correspond to the through hole of the irrigation pipeline to achieve precise irrigation. After the irrigation is completed, the air compressor unit generates negative pressure, and the telescopic tube retracts, thereby driving the sliding tube to reset.

[0060] (3) The sliding tube includes an end tube, an intermediate tube, an end plate, a ring plate and a sealing ring. When the sliding tube slides inside the irrigation pipe, the ring plate and the sealing ring on the end plate can be used to press against the inner wall of the irrigation pipe, thereby achieving partial sealing. In this way, after the water flows out of the water outlet groove on the intermediate tube, it will only flow out through the through hole located between the two sealing rings, thereby achieving precise irrigation and avoiding waste problems;

[0061] (4) The sliding tube is provided with a fixing plate and a fixing screw, which facilitates the connection and fixing of the end plate and the middle tube, and is also easy to remove later, which improves the convenience of cleaning and maintenance in case of blockage; at the same time, a heating pipe is provided corresponding to the water outlet, which can heat the water flowing out of the water outlet in the irrigation pipeline to meet the irrigation needs of the plants, thereby avoiding the water flow temperature being too low to affect the growth of the plants; the fixing screw and the heating pipe are arranged around the middle tube array, which improves the convenience of grouping;

[0062] (5) By setting a stirring assembly and a first adding tube, wherein the first adding tube is used as an adding assembly, it can deliver the medicine or fertilizer into the middle tube, and then the stirring roller is driven by the motor of the stirring assembly to rotate, so that the water flow and the medicine / fertilizer are fully mixed, thereby meeting the growth needs of the plants; by setting a one-way valve, the mixed water flow can be prevented from flowing into the telescopic tube, thereby ensuring that there is no sedimentation problem in the telescopic tube. In this way, when cleaning later, only the sliding tube needs to be cleaned;

[0063] (6) The telescopic tube is composed of a corrugated section, a percolation tube and a second addition tube. Thus, the second addition tube can be used to add chemicals or fertilizers into the percolation tube, so that the chemicals or fertilizers are mixed in the telescopic tube and then output through the middle tube of the sliding tube. Since a one-way valve and a first addition tube are provided, the second addition tube can be used only as a mixing line for chemicals or fertilizers, so as to avoid the problem of residue and subsequent mixing reaction between chemicals and fertilizers. Moreover, when cleaning, only the sliding tube needs to be cleaned, which improves the convenience of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0079] like Figures 1 to 12 As shown, the multi-channel water-fertilizer integrated irrigation unit of the present invention includes a water supply unit 1, an air compressor unit 2, an irrigation pipeline 3, a tee pipe 4, a mixing component 5 and an adding component.

[0080] like Figures 1 to 6 As shown, the water outlet of the water supply unit 1, the air inlet of the air compressor unit 2, and the water inlet of the irrigation pipeline 3 are each connected to one end of the tee pipe 4, and the water outlet of the water supply unit 1 and the air inlet of the air compressor unit 2 are both installed with on-off valves; the irrigation pipeline 3 is axially provided with a plurality of through holes 301; the mixing assembly 5 is slidably disposed within the irrigation pipeline 3 to selectively output water flow corresponding to the through holes 301; when the water supply unit 1 supplies water to the irrigation pipeline 3, the water outlet end of the mixing assembly 5 is controlled to be away from the tee pipe 4;

[0081] As described above, when the irrigation unit is deployed, the through hole 301 of the irrigation pipe 3 corresponds to the culture tray or other container for the plant;

[0082] During operation, the passage between the air compressor unit 2 and the tee pipe 4 is first cut off by the switch valve, and then the water supply unit 1 supplies water to the mixing assembly 5. The water then flows through the mixing assembly 5 and is output through the through hole 301 of the irrigation pipeline 3, thereby irrigating the corresponding culture tray.

[0083] The mixing assembly 5 is slidably disposed in the irrigation pipe 3. By increasing the water pressure, the mixing assembly 5 can be moved to correspond to different through holes 301 while delivering water for irrigation.

[0084] Specifically, after the culture tray corresponding to the first through hole 301 is irrigated, the water flow is increased and the water pressure is increased to move the mixing component 5 to the corresponding through hole 301, and the water flow is reduced, the water pressure is lowered, and the position of the mixing component 5 is kept stationary. After the corresponding through hole 301 is irrigated, the above steps are repeated to irrigate the subsequent culture tray; this achieves the effect of precise irrigation, effectively saves water resources, avoids water waste, and at the same time, each culture tray is irrigated with the same amount of water, so there will be no problem of uneven water distribution.

[0085] Furthermore, when the air compressor unit 2 is exhausting air, the water outlet end of the mixing component 5 is controlled to be close to the tee pipe 4; the adding component is used to supply medicine or fertilizer into the mixing component 5;

[0086] As in the above structure, the water supply unit 1 is used to supply irrigation water and also to drive the mixing and transporting component 5 to move, while the air compressor unit 2 is used to drive the mixing and transporting component 5 to reset.

[0087] Specifically, when the air compressor unit 2 is working, it extracts air to generate negative pressure, and then attracts the mixing and delivery component 5 to move back to its original position;

[0088] The adding component is used to supply medicine or fertilizer into the mixing component 5, so as to prevent and control plant diseases and supply nutrients.

[0089] In some embodiments, the air compressor unit 2 blows air to deliver water mist carrying medicines and fertilizers, which can meet the needs of plant leaf disease prevention and control and foliar fertilizer application, thereby achieving multi-purpose use.

[0090] like Figure 3 and Figure 4As shown, the mixing assembly 5 includes a telescopic tube 51 and a sliding tube 52. One end of the telescopic tube 51 is connected to the same pipe opening of the tee pipe 4 of the irrigation pipe 3 to form a coaxial structure; the sliding tube 52 is connected to the other end of the telescopic tube 51. The end of the sliding tube 52 away from the telescopic tube 51 is a sealed structure, and a water outlet groove 501 is formed on the circumference of the sliding tube 52.

[0091] As shown in the above structure, the mixing assembly 5 is composed of a telescopic tube 51 and a sliding tube 52. When the water supply unit 1 is supplying water, the water flows through the telescopic tube 51 into the sliding tube 52, and then flows out through the water outlet 501, and then through the through hole 301 for irrigation.

[0092] When the water supply unit 1 increases the water flow, as the water pressure increases, the telescopic tube 51 will be driven to extend, so that the water outlet end of the sliding tube 52 can move in the irrigation pipeline 3, thereby reaching other through holes 301; when the air compressor unit 2 is exhausting air, the telescopic tube 51 will retract, thereby driving the sliding tube 52 to return to its original position, thereby meeting the irrigation needs. It has the advantages of simple structure and convenient adjustment.

[0093] like Figure 4 and Figure 11 As shown, the sliding tube 52 includes an end tube 521, an intermediate tube 522, an end plate 523, a ring plate 524, and a sealing ring 525. One end of the end tube 521 is connected to the end of the telescopic tube 51 away from the tee tube 4, and the other end of the end tube 521 is connected to the intermediate tube 522. The water outlet 501 is provided on the circumference of the intermediate tube 522. The end plate 523 seals the end of the intermediate tube 522 away from the end tube 521. The ring plate 524 is provided on the end tube 521. A sealing ring 525 is provided on the circumference of each of the end plate 523 and the ring plate 524, and abuts against the inner wall of the irrigation pipe 3.

[0094] As shown in the above structure, the sliding tube 52 includes an end tube 521, an intermediate tube 522, an end plate 523, a ring plate 524, and a sealing ring 525. The end tube 521 is used to connect with the telescopic tube 51 to guide the water flow into the intermediate tube 522. The other end of the intermediate tube 522 is sealed by the end plate 523 to prevent water from overflowing, so that the water can only flow out through the water outlet 501.

[0095] Among them, the circumferential surfaces of the end plate 523 and the ring plate 524 are provided with sealing rings 525, so as to abut the inner wall of the irrigation pipe 3. In this way, the water flowing out of the water outlet trough 501 will only flow out through the through hole 301 located between the two sealing rings 525. Through the targeted setting of this structure, precise irrigation can be achieved and waste problems can be avoided.

[0096] like Figure 4 、 Figures 9-11As shown, the sliding tube 52 further includes a fixing plate 526, a heating tube 527, and a fixing screw 528. The water outlet grooves 501 are arranged in an array on the circumference of the intermediate tube 522 with the axis of the intermediate tube 522 as the reference. Multiple fixing plates 526 are arranged on the circumference of the intermediate tube 522, corresponding to the water outlet grooves 501. The heating tubes 527 and the fixing screw 528 are arranged corresponding to the water outlet grooves 501. One end of the heating tube 527 and the fixing screw 528 are connected to the fixing plate 526, and the other end is connected to the end plate 523.

[0097] As shown in the above structure, a fixing plate 526 is provided on the intermediate tube 522, so that the end plate 523 can be connected to the fixing plate 526 via a fixing screw 528, thereby integrating the end plate 523 with the intermediate tube 522. This structure is also convenient for disassembly and assembly, which is beneficial for subsequent cleaning and maintenance work to avoid blockage problems.

[0098] At the same time, a plurality of water outlet grooves 501 are provided on the middle tube 522. The fixing screws 528 and the heating tubes 527 are spaced apart and arranged around the middle tube 522. After the water flows out of the water outlet grooves 501, the heating tubes 527 can heat the water flowing out of the water outlet grooves 501 in the irrigation pipeline 3 to meet the irrigation needs of the plants, thereby preventing the water flow temperature from being too low and affecting the growth of the plants, and ensuring that the plants can carry out normal photosynthesis and transpiration.

[0099] This structure has the advantage of being easy to group and integrate; specifically, the portion of the intermediate tube 522 corresponding to the fixed screw 528 may not be provided with the water outlet trough 501.

[0100] like Figure 4 、 Figure 8 and Figure 12 As shown, the mixing assembly 5 further includes a power supply connection 53, a ring frame 54, and a cable 55. The end plate 523 includes an integrated circuit board for supplying power to the heating tube 527. The power supply connection 53 is electrically connected to the circuit board within the end plate 523. The ring frame 54 is disposed on a side of the end plate 523 away from the intermediate tube 522. One end of the cable 55 is connected to the ring frame 54, and the other end extends to the outside of the irrigation pipe 3.

[0101] As shown in the above structure, the mixing assembly 5 is provided with a power supply connection 53. Since the heating tube 527 is integrated between the end plate 523 and the ring plate 524, the control circuit board can be integrated into the end plate 523. When the heating tube 527 is in contact with the end plate 523, the electrical connection between the heating tube 527, the circuit board and the power supply connection 53 is simultaneously achieved, thereby facilitating power supply to the heating tube 527.

[0102] Furthermore, a ring frame 54 is provided on the end plate 523 for connecting the cable 55, so that the cable 55 can be used to drive the water outlet end of the mixing component 5 to move. At this time, there is no need to increase the water flow to push the mixing component 5 to move, which is more conducive to precise control of the irrigation water volume.

[0103] like Figure 4 As shown, the mixing assembly 5 further includes a stirring assembly 56 and a first addition pipe 57. The stirring assembly 56 includes a motor 561 and a stirring roller 562. The motor 561 is disposed on a side of the end plate 523, and the output shaft of the motor 561 passes through the end plate 523. The ring frame 54 surrounds the motor 561. The stirring roller 562 is connected to the output shaft of the motor 561 and is located within the intermediate pipe 522. The first addition pipe 57 is located within the ring frame 54, and one end of the first addition pipe 57 is connected to the end plate 523 and communicates with the intermediate pipe 522.

[0104] As shown in the above structure, the first addition pipe 57 is an addition component. When water is supplied to the sliding pipe 52, when water flows through the telescopic pipe 51 and enters the sliding pipe 52, the medicine or fertilizer is simultaneously fed into the sliding pipe 52 through the first addition pipe 57, thus realizing a two-way supply.

[0105] At the same time, the motor 561 of the stirring assembly 56 is activated, driving the stirring roller 562 to rotate in the middle tube 522 of the sliding tube 52, thereby achieving uniform mixing of the water flow and the medicine / fertilizer to better apply it to the plants, thereby meeting the growth needs of the crop plants;

[0106] Specifically, when arranging this structure, the motor 561 and the first adding pipe 57 are arranged in the ring frame 54, thereby fully utilizing the side space of the end plate 523, ensuring its compact structure and avoiding the impact of excessive volume on ease of use;

[0107] Specifically, with respect to the structure of the stirring roller 562, bristles are provided on its circumference to support the inner wall of the intermediate tube 522 with the bristles. In this way, when mixing and stirring, the inner wall of the intermediate tube 522 is brushed simultaneously, thereby avoiding crystallization and reducing the probability of blockage.

[0108] like Figure 4 As shown, the mixing assembly 5 further includes a one-way valve 58, which includes an annular plate 581, a slip ring 582, and a valve flap 583. The annular plate 581 is sleeved on the end of the stirring roller 562; a slip ring 582 is provided on both the inner and outer annular surfaces of the annular plate 581. The slip ring 582 on the inner annular surface is in sliding engagement with the stirring roller 562, and the slip ring 582 on the outer annular surface is in sliding engagement with the end pipe 521.

[0109] As in the above structure, by providing a one-way valve 58, the mixed water flow can be prevented from flowing into the telescopic tube 51, thereby ensuring that no sedimentation occurs in the telescopic tube 51. In this way, when cleaning later, only the sliding tube 52 needs to be cleaned, thereby preventing the normal growth of plants from being affected by the residual medicine when applied to different plants.

[0110] Specifically, when the one-way valve 58 is integrated, the two slip rings 582 are respectively slidably matched with the peripheral surface of the stirring roller 562 and the inner wall of the end tube 521, and the sliding seal is obtained;

[0111] Specifically, the one-way valve 58 may also be integrated on the stirring roller 562 or the end pipe 521 .

[0112] like Figure 5 and Figure 7 As shown, the telescopic tube 51 includes a corrugated section 511, a percolation tube 512, and a second addition tube 513. The corrugated section 511 and the percolation tube 512 are staggered. The percolation tube 512 is an annular tube having an inner cavity 502. The corrugated section 511 and the inner wall of the percolation tube 512 form a passage 503 of the telescopic tube 51, and the percolation tube 512 can percolate liquid into the passage 503. One end of the second addition tube 513 is connected to the percolation tube 512 and extends to the outside of the irrigation pipeline 3. The irrigation pipeline 3 has a chute 302 corresponding to the second addition tube 513.

[0113] As described above, regarding the structure of the telescopic tube 51, it is telescopic through the corrugated section 511, and the addition work is achieved through the percolation tube 512, wherein the passage 503 is the inner cavity of the telescopic tube 51;

[0114] Specifically, as the water pressure increases or negative pressure is attracted, the corrugated section 511 performs a telescopic movement, thereby causing the sliding tube 52 to move;

[0115] In specific operation, the percolation tube 512 has a separate inner cavity 502. The second addition tube 513 is an addition component. Chemicals or fertilizers are fed into the inner cavity 502 of the percolation tube 512 through the second addition tube 513. The supply pressure is appropriately increased, causing the chemicals or fertilizers to seep out of the percolation tube 512 and enter the passage 503 from the inner cavity 502. In this way, water and chemicals / fertilizers are mixed in the telescopic tube 51, thereby meeting the growth needs of plants.

[0116] In this structure, to avoid interference with the expansion and contraction of the telescopic tube 51, the irrigation pipe 3 is provided with a chute 302 for the second addition tube 513 to slide. To prevent leakage from the chute 302 during irrigation, the chute 302 is opened upward.

[0117] In this structure, due to the presence of the one-way valve 58, the second addition pipe 513 can be used only as a mixing pipe for the chemical or fertilizer. The other additive is supplied through the first addition pipe 57 to avoid residue and subsequent mixing reaction between the chemical and fertilizer.

[0118] In this way, only the sliding tube 52 needs to be cleaned during cleaning, thereby improving the convenience of maintenance.

[0119] In some embodiments, the second adding tube 513 is connected via a linear displacement component to drive the mixing component 5 to reset.

[0120] like Figure 7 As shown, the filtration tube 512 includes a ring tube 5121, a filtration membrane 5122, and a scraper ring 5123. The ring tube 5121 is a ring-shaped structure with a U-shaped cross-section and an opening facing inward. The filtration membrane 5122 is disposed on the inner side of the ring tube 5121 to form an inner cavity 502. The scraper ring 5123 is disposed on both sides of the ring tube 5121 and abuts against the inner wall of the irrigation pipe 3. The second addition tube 513 is connected to the ring tube 5121.

[0121] As in the above structure, the annular tube 5121 is configured as an annular structure with a U-shaped cross section, so that after the medicine or fertilizer is fed into the inner cavity 502, it can be supplied into the passage 503 through the percolation membrane 5122 to achieve mixing with the water flow;

[0122] The ring tube 5121 is configured as a rigid structure. When the telescopic tube 51 is extended or retracted, the ring tube 5121 only slides and does not deform. This prevents deformation of the filtration membrane 5122, thereby ensuring application stability.

[0123] Furthermore, scraper rings 5123 are provided on both sides of the ring tube 5121. When the corrugated section 511 drives the infiltration tube 512 to move, the scraper rings 5123 can scrape the inner wall of the irrigation pipeline 3 to remove water sediments, thereby avoiding subsequent impact on the normal displacement of the mixing component 5, thereby ensuring stable application.

[0124] The method of applying the multi-channel water-fertilizer integrated irrigation unit of the present invention comprises the following steps:

[0125] S1, cut off the passage between the tee pipe 4 and the air compressor unit 2 through the switch valve;

[0126] S2, water is fed into the telescopic pipe 51 of the mixing assembly 5 through the water supply unit 1, and the water flows into the sliding pipe 52 through the one-way valve 58.

[0127] S3, supply medicine or fertilizer into the sliding tube 52 through the first adding tube 57,

[0128] S4, the motor 561 of the stirring assembly 56 drives the stirring roller 562 to rotate to mix the water flow and the medicine or fertilizer, and simultaneously clean the inner wall of the middle tube 522.

[0129] S5, water flows through the outlet trough 501 into the irrigation pipe 3, and flows out through the through hole 301, thereby achieving irrigation;

[0130] During irrigation, the water flow is increased to push the telescopic tube 51 to stretch, thereby driving the sliding tube 52 to correspond to different through holes 301, or the cable 55 is pulled to drive the sliding tube 52 to move;

[0131] When irrigation is finished, the passage between the three-way pipe 4 and the water supply unit 1 is cut off by the switch valve, and then the air compressor unit 2 performs suction, forming a negative pressure in the telescopic tube 51, driving the sliding tube 52 to move back to its original position.

[0132] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
