At present, a fixed pipeline sprinkler irrigation system has been adopted for irrigation, but the cost of the fixed pipeline sprinkler irrigation system is relatively high, the equipment utilization rate is low, and usually drip holes are opened on the irrigation pipe. During the irrigation process, for the land that has already met the planting humidity, irrigation will still continue, resulting in waste of water resources. Based on this, a mobile irrigation device has emerged.

[0036] Garden plants are essential elements in the garden landscape. To improve the survival rate and growth quality of plants, maintenance work must be carried out. Among them, irrigation is a key factor affecting the survival rate of garden plants after planting. To improve the survival rate of planted saplings, it is necessary to irrigate the saplings regularly after planting to supplement the soil moisture in the garden green space and prevent the saplings from dying due to excessive water shortage. In the related art, a fixed pipeline sprinkler irrigation system is used to sprinkle the saplings. Although it is convenient and fast, there are problems such as high cost and low equipment utilization rate. Moreover, during the irrigation process, for the land far from the saplings and the land that has met the planting humidity, irrigation will still continue, resulting in waste of water resources.

[0037] To solve the above problems, the inventor tried to use a mobile irrigation device to manually move the container filled with irrigation water to the garden vegetation area and quantitatively irrigate the garden vegetation with a water pump. This reduces the cost investment of the irrigation system and reduces the waste of water resources. However, the inventor found through research that although irrigating the saplings with a mobile irrigation device has a certain water-saving effect, due to the complexity of the soil, for different soil textures and different irrigation cycles, the soil humidity is different. If a unified quantitative irrigation is adopted, it will still cause waste of water resources and the irrigation uniformity is not ideal.

[0038] In view of this, the embodiments of the present application provide a water-saving irrigation device that detects the humidity of the soil of the plants to be irrigated through a humidity sensor. The humidity sensor is electrically connected to a power pump, and the power pump is configured to control the liquid spraying situation of the liquid spraying member according to the humidity situation. Moreover, the liquid spraying member can rotate around the plants to be irrigated relative to the support member, can adjust the water volume of quantitative irrigation according to the humidity situation of the soil, and can improve the uniformity of irrigation around the plants to be irrigated.

[0039] The technical solution of the present application will be further described below through specific embodiments and drawings.

[0040] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the water-saving irrigation device provided by the embodiments of the present application; Figure 2It is a schematic structural diagram of a support member and a liquid spraying member provided by an embodiment of the present application. An embodiment of the present application discloses a water-saving irrigation device 100, which includes a liquid storage tank 1, a power pump 2, an irrigation assembly 3, and a humidity sensor 4. The liquid storage tank 1 is configured to hold irrigation liquid. The power pump 2 is disposed on the liquid storage tank 1 and is configured to pump the irrigation liquid in the liquid storage tank 1. The irrigation assembly 3 includes a support member 31 and a liquid spraying member 32. The support member 31 is disposed on the outer periphery of the liquid storage tank 1. The liquid spraying member 32 is movably connected to the support member 31 and is connected to the power pump 2. The liquid spraying member 32 can rotate around the plant to be irrigated relative to the support member 31 to irrigate the plant to be irrigated. The humidity sensor 4 is disposed on the support member 31 and is electrically connected to the power pump 2. The humidity sensor 4 is configured to detect the humidity of the soil of the plant to be irrigated. The power pump 2 is configured to control the liquid spraying condition of the liquid spraying member 32 according to the humidity condition.

[0041] It can be understood that the above-mentioned power pump 2 is configured to control the liquid spraying condition of the liquid spraying member 32 according to the humidity condition, including controlling the start and stop of the liquid spraying of the liquid spraying member 32 and controlling the liquid spraying amount of the liquid spraying member 32.

[0042] During the irrigation process, the humidity sensor 4 detects the soil humidity of the plant to be irrigated, and through the electrical connection between the humidity sensor 4 and the power pump 2, the measured humidity condition is fed back to the power pump 2. The power pump 2 starts to quantitatively extract the irrigation liquid from the liquid storage tank 1 according to this humidity condition and conveys it to the liquid spraying member 32 for irrigation. When the humidity of the soil reaches the planting humidity, the humidity sensor 4 sends a shutdown signal to the power pump 2, and the power pump 2 stops extracting the irrigation liquid, thereby realizing the adjustment of the amount of irrigation liquid for quantitative irrigation according to the humidity conditions of different soils, which is beneficial to saving the use of irrigation liquid and avoiding waste of irrigation liquid. At the same time, since the liquid spraying member 32 can rotate around the plant to be irrigated during the irrigation process, it can irrigate the surrounding of the plant to be irrigated, which is beneficial to improving the uniformity of irrigation and further improving the irrigation effect.

[0043] Optionally, the above-mentioned irrigation liquid includes water, nutrient solution, etc., and this embodiment does not limit this.

[0044] Optionally, the above-mentioned power pump 2 may include a vacuum water pump, a self-priming water pump, etc., and this embodiment does not limit this.

[0045] Optionally, the humidity sensor 4 includes a capacitive humidity sensor, a resistive humidity sensor, a thermal energy humidity sensor, etc., which are not limited in this embodiment. Exemplarily, the humidity sensor 4 is set as a CSF humidity sensor. In this way, since the CSF humidity sensor has low sensitivity to high-salt and viscous soils and strong anti-interference ability, it can improve the detection accuracy of soil humidity, which is beneficial to better adjust the liquid spraying condition of the power pump 2. At the same time, due to the characteristics of small volume and high protection of the CSF humidity sensor, it is convenient to be installed on the water-saving irrigation device 100, and it is beneficial to reduce the maintenance frequency of the water-saving irrigation device 100 and increase the service life of the water-saving irrigation device 100.

[0046] Optionally, the above-mentioned support member 31 may include, for example, a rod-shaped structure, a plate-shaped structure, a block-shaped structure, etc., which are not limited in this embodiment.

[0047] In some alternative embodiments, in order to facilitate the movement of the liquid storage tank, a plurality of universal wheels (not shown) may be provided on the bottom surface of the liquid storage tank 1.

[0048] In some other alternative embodiments, as Figure 1 shown, the water-saving irrigation device 100 further includes a chassis 8, the liquid storage tank 1 is arranged on the chassis 8, and universal wheels 9 are provided at the bottom of the chassis 8. The chassis 8 is used to carry the liquid storage tank 1. At the same time, the chassis 8 can move through the universal wheels at the bottom, thereby driving the movement of the liquid storage tank 1 and realizing the movement of the water-saving irrigation device 100 between the plants to be irrigated; moreover, the universal wheels 9 can reduce the friction of the movement of the water-saving irrigation device 100, making the movement more convenient and smooth.

[0049] Optionally, there are multiple universal wheels 9, such as three, four, five, six, etc., which are not limited in this embodiment. Exemplarily, as Figure 1 shown, there are four universal wheels 9, and the four universal wheels 9 are equidistantly arranged at the edge position of the chassis 8. The four universal wheels 9 can stably support the chassis 8, avoiding the situation that the water-saving irrigation device 100 tilts and falls, which is beneficial to reducing the risk of damage to the water-saving irrigation device 100. At the same time, setting the universal wheels 9 to four can reduce the number of universal wheels 9 used, which is beneficial to reducing the production cost of the water-saving irrigation device 100.

[0050] In some embodiments, a push handle (not shown) is provided on one side of the liquid storage tank 1, and the push handle is configured to push the liquid storage tank 1 to move.

[0051] In some other embodiments, as Figure 1 shown, a push handle 10 is provided on one side of the chassis 8, and the push handle 10 is configured to push the chassis 8 to move. Through the push handle 10, it is convenient for manual grasping to facilitate the manual pushing of the water-saving irrigation device 100.

[0052] In some embodiments, such as Figure 1 and Figure 2 shown, the support member 31 can be a long strip plate-like structure. One end of the support member 31 is disposed on the outer peripheral surface of the liquid storage tank 1, and the other end of the support member 31 extends along a direction away from the liquid storage tank 1. The liquid spraying member 32 is slidably disposed at the other end of the support member 31, that is, the liquid spraying member 32 is disposed away from the liquid storage tank 1.

[0053] Optionally, a sliding cooperation portion 311 is provided on the support member 31. The liquid spraying member 32 includes a sliding portion 321 and a plurality of nozzles 322. An arc-shaped track 3211 is provided on the sliding portion 321. The arc-shaped track 3211 is configured to extend along the outer periphery of the plant to be irrigated. The arc-shaped track 3211 is slidably connected to the sliding cooperation portion 311 so that the sliding portion 321 can rotate around the plant to be irrigated. The plurality of nozzles 322 are connected to the power pump 2. The plurality of nozzles 322 are spaced apart and disposed at the bottom of the sliding portion 321 to irrigate the plant to be irrigated. Through the cooperation of the arc-shaped track 3211 and the sliding cooperation portion 311, on the one hand, a supporting force in the height direction of the liquid storage tank 1 is provided for the liquid spraying member 32 to realize the suspension of the liquid spraying member 32; on the other hand, guidance and limitation are provided for the rotation of the liquid spraying member 32 around the plant to be irrigated to prevent the rotation track of the liquid spraying member 32 from deviating. At the same time, it can also make the rotation of the liquid spraying member 32 relative to the support member 31 smoother.

[0054] Optionally, the above-mentioned sliding cooperation portion 311 includes a pulley, a slider, etc., and this embodiment does not limit this. Exemplarily, such as Figure 2 shown, the sliding cooperation portion 311 is set as a pulley, so that the friction between the sliding portion 321 and the sliding cooperation portion 311 is rolling friction, which is beneficial to reducing the friction of the liquid spraying member 32 rotating relative to the support member 31, further making the rotation smoother, and at the same time reducing the energy consumption required for driving the rotation, which is beneficial to reducing the use cost of the water-saving irrigation device 100.

[0055] Optionally, such as Figure 2 shown, the water-saving irrigation device 100 further includes a connecting hose 21. The connecting hose 21 is connected to the power pump 2, and the plurality of nozzles 322 are connected to the connecting hose 21. By adopting the connecting hose 21, when the liquid spraying member 32 rotates relative to the support member 31, the plurality of nozzles 322 can still be kept connected to the power pump 2.

[0056] As an alternative embodiment, the sliding portion 321 can be a square block, a rectangular block, a semi-circular block, etc., and this embodiment does not limit this. Exemplarily, such as Figure 1As shown, the sliding part 321 is arranged as a semi-circular block, and the arc-shaped track 3211 extends along the extending direction of the semi-circular block. In this way, on the one hand, it is convenient to arrange the arc-shaped track 3211, making the structure of the sliding part 321 more concise and beautiful; on the other hand, the sliding part 321 does not require a large size to meet the arrangement of the arc-shaped track 3211 or add additional structures to arrange the arc-shaped track 3211, which is beneficial to reducing the mass of the sliding part 321 and improving the connection stability between the liquid spraying part 32 and the support part 31.

[0057] In some embodiments, the water-saving irrigation device 100 further includes a rotary drive assembly 5. The rotary drive assembly 5 includes a first rotary drive member 51 and a gear 52. The first rotary drive member 51 is arranged at one end of the support part 31 away from the liquid storage tank 1. The gear 52 is connected to the first rotary drive member 51. A tooth groove 3212 is provided on the sliding part 321. The tooth groove 3212 is configured to extend along the outer periphery of the plant to be irrigated, and the tooth groove 3212 is arranged at an interval from the arc-shaped track 3211. The gear 52 meshes with the tooth groove 3212. The first rotary drive member 51 is configured to drive the gear 52 to rotate, so that the sliding part 321 rotates around the plant to be irrigated.

[0058] The first rotary drive member 51 drives the gear 52 to rotate, driving the tooth groove 3212 to move, thereby realizing driving the sliding part 321 to rotate around the plant to be irrigated; at the same time, by driving the rotation of the sliding part 321 through the first rotary drive member 51, the rotation of the sliding part 321 around the plant to be irrigated is more controllable; and, through the cooperation and speed reduction of the gear 52 and the tooth groove 3212, the rotation speed of the sliding part 321 is more controllable, and more precise control can be achieved.

[0059] Optionally, the above-mentioned first rotary drive member 51 can be arranged as a servo motor, a stepping motor, etc., and this embodiment does not limit this.

[0060] As an alternative implementation manner, a plurality of the above-mentioned arc-shaped tracks 3211 are provided, and a plurality of sliding fit parts 311 are correspondingly provided. The plurality of arc-shaped tracks 3211 are respectively slidably connected to the plurality of sliding fit parts 311. It can be understood that the plurality of arc-shaped tracks 3211 can be arranged as two, three, four, etc., and this embodiment does not limit this. Exemplarily, such as Figure 2As shown in the figure, there are two arc-shaped tracks 3211, and two sliding fitting parts 311 are correspondingly provided. The two arc-shaped tracks 3211 are respectively slidably connected to the two sliding fitting parts 311. The two arc-shaped tracks 3211 extend along the outer periphery of the plants to be irrigated and are arranged in parallel to each other. The tooth grooves 3212 are arranged between the two arc-shaped tracks 3211. Through the sliding connection between the two arc-shaped tracks 3211 and the two sliding fitting parts 311, the connection between the sliding part 321 and the support member 31 is made tighter, avoiding the situation where the sliding part 321 is skewed relative to the support member 31, so that the tooth grooves 3212 can be tightly engaged with the gear 52; at the same time, the rotation of the sliding part 321 is made smoother and more stable.

[0061] As an alternative embodiment, a plurality of tooth-shaped structures are provided at intervals on the side wall surface of the arc-shaped track 3211 along the rotation direction of the sliding part 321 to form the tooth grooves 3212. In this way, the structure of the water-saving irrigation device 100 can be made more compact.

[0062] As an alternative embodiment, the support member 31 is slidably arranged in the liquid storage tank 1. The support member 31 can move relative to the liquid storage tank 1 along the height direction Y of the liquid storage tank 1 so that the humidity sensor 4 extends into the soil to detect the humidity of the soil. By using the way that the support member 31 is slidably connected to the liquid storage tank 1, it can be realized that the humidity sensor 4 can extend into the soil to detect the humidity of the soil. At the same time, before moving the water-saving irrigation device 100, by moving the support member 31 along the height direction Y of the liquid storage tank 1, the humidity sensor 4 can be extended out of the soil, avoiding the damage of the humidity sensor 4 caused by the collision between the humidity sensor 4 and the soil when moving the water-saving irrigation device 100.

[0063] Optionally, the support member 31 is slidably arranged in the liquid storage tank 1, and the support member 31 can be moved relative to the liquid storage tank 1 along the height direction Y by manual adjustment, for example; or, it can be realized by means of electrically driving the support member 31 to move relative to the liquid storage tank 1 along the height direction Y and the like.

[0064] Exemplarily, the water-saving irrigation device 100 further includes a linear driving member (not shown in the figure). When the support member 31 is slidably arranged in the liquid storage tank 1, the linear driving member is arranged on the liquid storage tank 1, and the driving end of the linear driving member is connected to the support member 31. The linear driving member is used to drive the support member 31 to move along the height direction Y so that the humidity sensor 4 extends into the soil to detect the humidity of the soil. Through the driving of the linear driving member, it is realized that the humidity sensor 4 can move along the height direction Y; and, through the linear driving member, the movement of the humidity sensor 4 along the height direction Y is made more controllable.

[0065] As another alternative embodiment, the humidity sensor 4 can be slidably arranged at the other end of the support member 31, that is, the humidity sensor 4 is arranged close to the liquid spraying member 32. The humidity sensor 4 can move relative to the support member 31 along the height direction Y of the liquid storage tank 1 so as to extend into the soil to detect the humidity condition of the soil. By adopting this embodiment, the size of the component for enabling the humidity sensor 4 to extend into the soil can be made relatively small, which is beneficial to reducing the weight of the water-saving irrigation device 100 and facilitating the movement of the water-saving irrigation device 100; moreover, without moving the liquid spraying member 32 connected to the support member 31, it is possible to reduce the possible collision between the liquid spraying member 32 and the branches and leaves of the plants to be irrigated after adjusting the height, and avoid damaging the liquid spraying member 32 or the plants to be irrigated.

[0066] Optionally, the humidity sensor 4 can be slidably arranged at the other end of the support member 31, and the humidity sensor 4 can be moved relative to the support member 31 along the height direction Y by, for example, manual adjustment; or, the humidity sensor 4 can be moved relative to the support member 31 along the height direction Y by means of electric drive and the like.

[0067] Exemplarily, as Figure 1 and 2 shown, the water-saving irrigation device 100 further includes a linear drive member 6. When the humidity sensor 4 is slidably arranged on the support member 31, the linear drive member 6 is arranged on the support member 31, the drive end of the linear drive member 6 is connected to the humidity sensor 4, and the linear drive member 6 is used to drive the humidity sensor 4 to move along the height direction Y so as to extend into the soil to detect the humidity condition of the soil. By adopting this setting, while enabling the humidity sensor 4 to move along the height direction Y through the linear drive member 6 and making the movement more controllable, directly driving the humidity sensor 4 by the linear drive member 6 can also reduce the operating power of the linear drive member 6 and lower the usage cost of the water-saving irrigation device 100.

[0068] It can be understood that the above-mentioned linear drive member 6 can include an electric push rod, a cylinder, etc., and the present embodiment does not limit this.

[0069] Optionally, as Figure 2As shown, when the humidity sensor 4 is slidably arranged on the support member 31, a guide assembly 312 is arranged on the support member 31, and the guide assembly 312 includes a sleeve 3121, a limit block 3122 and an insert block 3123. The sleeve 3121 is arranged at the bottom of the support member 31, and the sleeve 3121 extends along the height direction Y of the liquid storage tank 1. The inner wall surface of the sleeve 3121 is provided with a limit groove 312a along the height direction Y. The limit block 3122 is slidably connected to the limit groove 312a. The limit block 3122 is connected to the driving end of the linear drive member 6, and the insert block 3123 is connected to the bottom of the limit block 3122. The humidity sensor 4 is arranged on the side of the insert block 3123 away from the limit block 3122. The linear drive member 6 is configured to drive the limit block 3122 to slide along the limit groove 312a, so that the insert block 3123 drives the humidity sensor 4 to extend into the soil along the height direction Y to detect the humidity of the soil.

[0070] The humidity sensor 4 is connected to the linear drive member 6 by the stopper block 3122 and the insert block 3123, and the movement of the humidity sensor 4 is guided and limited by the stopper groove 312a, so that the movement stroke of the humidity sensor 4 is more controllable and the movement trajectory of the humidity sensor 4 is prevented from deviating. In addition, the stopper groove 312a and the stopper block 3122 are arranged in the sleeve 3121, so that the sliding connection between the stopper groove 312a and the stopper block 3122 can be prevented from being invaded by soil and affecting the smoothness of sliding.

[0071] Optionally, the insert block 3123 is configured to be conical, so that the conical insert block 3123 can be better inserted into the soil, thereby making it easier to drive the humidity sensor 4 to extend into the soil.

[0072] Optionally, there are two limit grooves 312a, which are arranged opposite to each other, and two convex parts (not shown) are correspondingly arranged at both ends of the limit block 3122, which are slidably connected to the limit grooves 312a. The limit block 3122 cooperates with the two limit grooves 312a to make the force between the convex parts and the limit grooves 312a more uniform, so that the movement of the humidity sensor 4 along the height direction Y is more stable and smooth.

[0073] Please combine Figure 3 , Figure 3It is a schematic diagram of the internal structure of the water storage tank provided by an embodiment of the present application. In some embodiments, the water-saving irrigation device 100 further includes a stirring mechanism 7. The stirring mechanism 7 includes a second rotation driving member 71, a stirring shaft 72, and a coupling 73. An installation groove 15 is provided at the bottom of the liquid storage tank 1. The second rotation driving member 71 is arranged in the installation groove 15. The driving shaft of the second rotation driving member 71 is connected to the coupling 73. One end of the stirring shaft 72 is connected to the coupling 73, and the stirring shaft 72 is arranged in the liquid storage tank 1 along the height direction Y of the liquid storage tank. The second rotation driving member 71 is used to drive the stirring shaft 72 to rotate, and the stirring shaft 72 is configured to stir the irrigation liquid in the liquid storage tank 1. Arranging the second rotation driving member 71 in the installation groove 15 at the bottom of the liquid storage tank 1 makes the structure of the water-saving irrigation device 100 more compact. At the same time, when it is necessary to fertilize the plants to be irrigated, fertilizers are added to the liquid storage tank 1, and the irrigation liquid in the liquid storage tank 1 is stirred through the cooperation of the second rotation driving member 71 and the stirring shaft 72, so that the fertilizers can be dispersed.

[0074] Optionally, the second rotation driving member 71 includes a servo motor, a stepping motor, a torque motor, etc., and the present embodiment does not limit this.

[0075] In some embodiments, such as Figure 3 shown, an observation window 11 for observing the internal situation of the liquid storage tank 1 and a liquid level scale 12 extending along the height direction Y of the liquid storage tank 1 are provided on the outer peripheral surface of the liquid storage tank 1. The liquid level scale 12 is located on the outer periphery of the observation window 11. By adopting the cooperation mode of the observation window 11 and the liquid level scale 12, it is convenient to check the volume of the irrigation liquid in the liquid storage tank 1, so as to facilitate timely replenishment of the irrigation liquid, or facilitate better planning of the irrigation route of the water-saving irrigation device 100 according to the volume of the irrigation liquid.

[0076] In other embodiments, an observation window 11 for observing the internal situation of the liquid storage tank 1 and a liquid level scale (not shown in the figure) extending along the height direction Y of the liquid storage tank 1 are provided on the outer peripheral surface of the liquid storage tank 1. The liquid level scale coincides with the observation window 11. Coinciding the liquid level scale with the observation window 11 can more accurately read the volume of the irrigation liquid in the liquid storage tank 1.

[0077] In some embodiments, such as Figure 3As shown, the liquid storage tank 1 further includes a sealing cover 13a and a filter cartridge 14. The top end of the liquid storage tank 1 is provided with a liquid injection hole 13. The sealing cover 13a is configured to close the liquid injection hole 13. The filter cartridge 14 is arranged at the inner top end of the liquid storage tank 1 corresponding to the liquid injection hole 13. Through the liquid injection hole 13, irrigation liquid can be added into the liquid storage tank 1. At the same time, impurities in the irrigation liquid can be filtered through the filter cartridge 14 to prevent impurities from entering the interior of the liquid storage tank 1, causing blockage of the irrigation pipeline or damage to the power pump 2. In addition, through the sealing cover 13a, the irrigation liquid in the liquid storage tank 1 can be prevented from being polluted by harmful substances that may exist in the external environment.

[0078] In some embodiments, a storage battery (not shown) and a control panel (not shown) are installed at the bottom of the chassis 8. The humidity sensor 4, the first rotary drive member 51, the second rotary drive member 71, and the linear drive member 6 are all electrically connected to the control panel, and the control panel is electrically connected to the storage battery. Thus, when the water-saving irrigation device 100 is in use, the storage battery can supply electrical energy to the humidity sensor 4, the first rotary drive member 51, the second rotary drive member 71, and the linear drive member 6, and the operation of the humidity sensor 4, the first rotary drive member 51, the second rotary drive member 71, and the linear drive member 6 can be controlled through the control panel.

[0079] The following briefly describes the watering process of the water-saving irrigation device 100 of the present application:

[0080] When watering the plants to be irrigated, the water-saving irrigation device 100 is pushed by the push handle 10 until the liquid spraying member 32 is located around the plants to be irrigated, and the control panel is turned on. The control panel controls the linear drive member 6 and the humidity sensor 4 to turn on. The linear drive member 6 pushes the conical plug 3123 into the soil, so that the humidity sensor 4 is inserted into the soil. The control panel controls the linear drive member 6 to turn off. At this time, the humidity sensor 4 can detect the humidity of the soil and feedback the humidity condition to the control panel.

[0081] If the humidity condition is lower than the humidity requirement for planting, the control panel controls the power pump 2 and the first rotary drive member 51 to open. The power pump 2 pumps the irrigation liquid in the liquid storage tank 1 and transmits it to the liquid spraying member 32. Multiple nozzles 322 spray the irrigation liquid to irrigate the plants to be irrigated. At the same time, the first rotary drive member 51 drives the gear 52 to rotate, driving the liquid spraying member 32 to rotate, so as to irrigate the surroundings of the plants to be irrigated. At this time, the humidity sensor 4 continuously detects the humidity condition of the soil. When the humidity condition of the soil reaches the humidity requirement for planting, the humidity sensor 4 feeds back the humidity condition to the control panel, and the control panel controls the power pump 2 and the first rotary drive member 51 to close, so that the water-saving irrigation device 100 stops irrigating. Then, the control panel controls the linear drive member 6 to open, and the linear drive member 6 drives the tapered plug 3123 to extend out of the soil, so as to drive the humidity sensor 4 to extend out of the soil. The water-saving irrigation device 100 is pushed to the periphery of the next plant to be irrigated through the push handle 10, and the above process is repeated.

[0082] If the humidity condition meets the humidity requirement for planting, the control panel controls the linear drive member 6 to open, and the linear drive member 6 drives the tapered plug 3123 to extend out of the soil, so as to drive the humidity sensor 4 to extend out of the soil. The water-saving irrigation device 100 is pushed to the periphery of the next plant to be irrigated through the push handle 10, and the above process is repeated.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
