Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology, specifically relating to a soil moisture tester for gardens. Background Technology

[0002] In modern landscaping, soil moisture management is crucial for the healthy growth of garden plants and the long-term maintenance of garden landscapes. Soil moisture not only affects the absorption of water and nutrients by plant roots, but also relates to the activity of microorganisms and the stability of soil structure, directly influencing the overall growth status of garden plants and the overall landscape effect.

[0003] Traditional methods for monitoring soil moisture in gardens have significant drawbacks. Previously, they relied heavily on manual experience, with garden maintenance workers estimating soil moisture levels by observing its appearance and touching its texture. However, this method is highly subjective, inaccurate, and prone to errors due to differing judgment standards among individuals, especially in complex garden environments. Furthermore, manual monitoring is time-consuming and labor-intensive, requiring substantial manpower and time in large garden areas. It is difficult to achieve real-time, comprehensive monitoring, and the inability to promptly detect abnormal changes in soil moisture can delay optimal plant care.

[0004] With the expansion of garden scale and the increasing demands for refined management, the need for accurate and efficient monitoring of soil moisture is becoming increasingly urgent. Large-scale garden projects such as urban parks and municipal green spaces have a wide variety of plant species and complex layouts. Different plants have different soil moisture requirements, and traditional monitoring methods cannot meet these diverse maintenance needs. At the same time, water resources are becoming increasingly precious, and accurately controlling soil moisture for rational irrigation and avoiding water waste has become a key consideration for the sustainable development of gardens. Against this backdrop, garden soil moisture testers have emerged. Leveraging advanced sensing technology and intelligent data processing capabilities, they provide a scientific and reliable solution for monitoring garden soil moisture, helping garden maintenance and management reach new heights of precision and intelligence.

[0005] When using existing portable soil moisture meters, users need to hold the device and insert the probe into the soil to measure its moisture content. However, when holding the device and inserting the probe into the soil, users are prone to accidentally pressing the buttons on the device, which may change the original measurement parameters and lead to inaccurate data. Accidental button presses may also trigger unnecessary functions of the instrument, such as starting unnecessary data storage and transmission, causing data corruption and interfering with subsequent analysis and comparison of historical measurement data, making it impossible to accurately track the trend of soil moisture changes. Utility Model Content

[0006] The purpose of this invention is to provide a soil moisture tester for gardens, aiming to solve the problem that existing portable soil moisture detectors require users to hold the device and insert the probe into the soil to test its moisture content. However, when holding the device and inserting the probe into the soil, users are prone to accidentally pressing the buttons on the device, which may change the original measurement parameters and lead to inaccurate measurement data. In addition, accidental button presses may also trigger unnecessary functions of the instrument, such as starting unnecessary data storage and transmission, causing data chaos, interfering with subsequent analysis and comparison of historical measurement data, and making it impossible to accurately track the trend of soil moisture changes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil moisture tester for gardens, comprising a tester body, a control button on the front surface of the tester body, the tester body surface being snapped into the inner wall of a housing, a sliding groove on the front surface of the housing, a front baffle slidably connected to the sliding groove surface, a limiting groove on the top inner wall of the front baffle, a rod movably connected to the limiting groove surface, a limiting disc connected to the rod surface, a spring on the rod surface, the other side of the spring being connected to the inner wall of the front baffle, the other side of the rod being inserted into a circular groove surface, the circular groove being on the front surface of the housing, an elastic band bonded to the side of the housing away from the tester body, a receiving tube connected to the lower section of the housing surface, a slot on the inner wall of the receiving tube, a test head inserted into the slot surface, a limiting cover fitted onto the top of the test head, locking plates on the surface of the limiting cover, rubber protrusions on the locking plates engaging with the surface of a clamping plate.

[0008] As a preferred embodiment of the soil moisture tester for gardening according to this utility model, the top surface of the back side of the front baffle is provided with an "L"-shaped protrusion, and the shape and size of the protrusion are adapted to the groove.

[0009] As a preferred embodiment of the soil moisture tester for gardening according to this utility model, the front baffle, the limiting groove, the insertion rod and the spring form an elastic connection structure.

[0010] As a preferred embodiment of the soil moisture tester for gardening according to this utility model, the front end of the casing has two sets of circular grooves, and the shape and size of the circular grooves are adapted to the lateral end of the insertion rod.

[0011] As a preferred embodiment of the soil moisture tester for gardening of this utility model, the inner wall of the elastic band is provided with four sets of annular rubber sleeves arranged longitudinally at equal intervals.

[0012] As a preferred embodiment of the soil moisture tester for gardens according to this utility model, the shape and size of the slot are adapted to the lower section of the test head.

[0013] As a preferred embodiment of the soil moisture tester for gardening according to this utility model, a circular groove is provided on one side of the clamping plate, and the shape and size of the groove are adapted to the rubber protrusions on the surface of the clamping plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides the following technical solution: a soil moisture tester for gardens, comprising a tester body 1, a control button 2 on the front surface of the tester body 1, the surface of the tester body 1 being snapped into the inner wall of a housing 3, a sliding groove 4 on the front surface of the housing 3, a front baffle 5 slidably connected to the surface of the sliding groove 4, a limiting groove 6 on the top inner wall of the front baffle 5, a movably connected insertion rod 7 on the surface of the limiting groove 6, a limiting disc connecting a spring 8 on the surface of the insertion rod 7, the other side of the spring 8 being connected to the inner wall of the front baffle 5, the other side of the insertion rod 7 being inserted into the surface of a circular groove 9, the circular groove 9 being opened on the front surface of the housing 3, and the surface of the housing 3 away from the tester body 1 being bonded. The elastic band 10 and the lower part of the casing 3 are connected to the storage tube 11. The inner wall of the storage tube 11 has a slot 12. The detection head 13 is inserted into the surface of the slot 12. The top of the detection head 13 is fitted with a limiting cover 14. The surface of the limiting cover 14 is provided with a locking plate 15. The rubber protrusions on the surface of the locking plate 15 are engaged with the surface of the clamping plate 16. In this design, the detector body 1, the control button 2 and the detection head 13 constitute the main body of the soil moisture detector. A large number of related components are set in the main body of the soil moisture detector. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.

[0027] The main model of the soil moisture detector in this solution is: AIFLI-TRSC200.

[0028] In use: It typically operates using the frequency domain reflection (FDR) principle. Its detection head 13 has specific metal electrodes. When inserted into the soil, the instrument emits electromagnetic waves of a specific frequency into the soil. Because the moisture content in the soil varies, it also affects the dielectric constant of the electromagnetic waves; the higher the moisture content, the greater the dielectric constant. As the electromagnetic waves propagate through the soil, their transmission speed, phase, and other parameters change with the soil's dielectric constant. The instrument detects these changes and uses a built-in algorithm to convert the relevant parameters into soil moisture content data, which is then displayed intuitively on the screen. This allows users to quickly and accurately understand the soil moisture status, facilitating efficient monitoring of soil moisture in gardens.

[0029] Preferably, the top surface of the back side of the front baffle 5 is provided with an "L"-shaped protrusion, and the shape and size of the protrusion are adapted to the groove 4.

[0030] In practical use, the front baffle 5 is pulled down so that the protrusion on its top slides down on the groove 4, thereby limiting the range of motion of the front baffle 5 at the front end of the housing 3.

[0031] Preferably, the front baffle 5, the limiting groove 6, the insert rod 7 and the spring 8 form an elastic connection structure.

[0032] In practical use, the insert rod 7, which is elastically connected to the inner wall of the front baffle 5, is inserted into the round groove 9 at the bottom front end of the housing 3 by the rebound of the connected spring 8.

[0033] Preferably, the front end of the casing 3 has two sets of circular grooves 9, and the shape and size of the circular grooves 9 are adapted to the horizontal end of the insertion rod 7.

[0034] In practical use, the insert rod 7, which is elastically connected to the inner wall of the front baffle 5, is inserted into the round groove 9 at the bottom front end of the housing 3 by the rebound of the connected spring 8, thereby fixing the position of the front baffle 5 at the front end of the housing 3.

[0035] Preferably, the inner wall of the elastic band 10 is provided with four sets of annular rubber sleeves at equal intervals in the longitudinal direction.

[0036] In practical use, four sets of annular rubber sleeves with equal spacing and longitudinal distribution on the inner wall of the elastic band 10 are used to make it convenient for the user to insert their fingers into the inner wall of the elastic band 10 when holding the casing 3, so as to avoid dropping the device and damaging the main body 1.

[0037] Preferably, the shape and size of the slot 12 are adapted to the lower section of the detection head 13.

[0038] In practical use, the slot 12 is used to fix the position of the detection head 13 while protecting its bottom tip to prevent it from being bumped or damaged.

[0039] Preferably, a circular groove is provided on one side of the clamping plate 16, and the shape and size of the groove are adapted to the rubber protrusions on the surface of the clamping plate 15.

[0040] In practical use, pinch the locking plates 15 on both sides of the limiting cover 14 and tilt them towards the limiting cover 14. This will pull the limiting cover 14 upward and at the same time drive the locking plate 15 at its bottom to disengage from the locking clamp 16.

[0041] Working principle: In garden soil management, the moisture content of the soil is detected by the cooperation of the detector body 1 and the detection head 13, so as to facilitate timely adjustment of soil conditions to maintain the green plants in the garden. When using the detector body 1 for detection, first pinch the locking plates 15 on both sides of the limiting cover 14 and tilt it to one side of the limiting cover 14. At the same time, pull the limiting cover 14 upward and drive the locking plate 15 at the bottom to disengage from the clamping plate 16. Then, pull out the limiting cover 14 that is covering the top of the detection head 13, take out the detection head 13 inserted in the storage tube 11, and then use the mounting mechanism on the top of the detection head 13 to fix it on the reserved mounting port on the top of the detector body 1.

[0042] At this point, the insert rod 7, which is inserted into the circular groove 9 at the top front end of the housing 3, can be pulled outwards. Then, the front baffle 5 is pulled down so that the protrusion at its top slides down on the slide groove 4, thereby exposing the control button 2, which is covered by the front baffle 5. The control button 2 is then used to set the upcoming test. At the same time, when the front baffle 5 is pulled down to the bottom of the slide groove 4, the insert rod 7, which is elastically connected to the inner wall of the front baffle 5, can be inserted into the circular groove 9 at the bottom front end of the housing 3 by the rebound of the connected spring 8, thereby fixing the front baffle 5 in the position below the control button 2. After the operation is completed, the above operation is repeated. The insert rod 7, which is inserted into the circular groove 9 at the bottom front end of the housing 3, is pulled out, and then the front baffle 5 is slid upwards. The control button 2 is again blocked from the front end. The spring 8 connecting the upper limit plate of the rod 7 and the inner wall of the front baffle 5 causes the rod 7 to be inserted into the round groove 9 at the front end of the housing 3. This fixes the front baffle 5 and blocks the position of the control button 2, thus protecting the control button 2 and preventing accidental contact with the control button 2 when the detector body 1 is inserted into the soil. Then, hold the housing 3 with one hand and use your fingers to pass through the elastic band 10 on the back of the housing 3 to stabilize the detector body 1. Then, insert the detection head 13 into the soil to be tested so that the detection head 13 can detect the dryness and moisture of the soil, which facilitates the recording and management of the soil conditions by gardeners.

[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
