Description

Technical Field

[0001] The present invention relates to the technical field of sensors, and specifically to a leaf temperature and humidity sensor. Background Art

[0002] The leaf temperature and humidity sensor accurately measures the temperature and humidity of the leaf surface to detect the growth environment of plant leaves, achieving the purpose of preventing pests and diseases. It can more accurately reflect the situation of the leaf surface environment. Its shape adopts a leaf-like design to truly simulate the characteristics of the leaf surface, thus being able to more accurately reflect the situation of the leaf surface environment. In the prior art, the installation of temperature and humidity sensors mostly adopts fixing methods such as gluing, drilling, or direct placement. The former is easily detached due to the influence of temperature and humidity changes; the latter easily damages the cleanliness and integrity of plant leaves. In addition, the shapes of the leaves and branches of general plants are not easy to fix, so the fixing work is complicated, inefficient, and time-consuming.

[0003] In order to overcome the above defects, a leaf humidity sensor with the publication number CN217356412U includes a clamping mechanism, an adjusting mechanism, and a plurality of humidity probes. The clamping mechanism is connected to the adjusting mechanism. The adjusting mechanism includes a mounting plate, a plurality of hinge columns, and a plurality of fixed sleeves. The humidity probes are fixed on the fixed sleeves. The fixed sleeves are sleeved on the hinge columns and fixed by positioning set screws. One ends of the plurality of hinge columns are hinged to the mounting plate, and the mounting plate is hinged to the clamping mechanism. A leaf humidity sensor adopting the above structure has reliable fixation, convenient installation, and is convenient to adjust the positions of the humidity probes according to the shape and size of the detected plant leaves, improving the accuracy of the collected data.

[0004] Although the existing design can solve the above problems, the fixation design for the leaves is too simple and not applicable to the internal clamping environments of various plants. Most of the existing designs are direct placement, which may cause the sensing surface to be blocked, resulting in inaccurate measurement data and there may also be a risk of falling. Moreover, the design of the sensing surface is small, and if it is blocked, it will also lead to inaccurate final measurement data. And the small sensing surface affects the measurement accuracy of the data and cannot well reflect the real data. Summary of the Invention

[0005] The object of the present invention is to provide a leaf temperature and humidity sensor to solve the problems in the above-mentioned background technology. The fixed design for the leaf is too simple and not applicable to the interior of various plant clamping environments. Most of the existing designs are to directly place it, which may cause the sensing surface to be blocked, resulting in inaccurate measurement data and there may also be a risk of falling. Moreover, the design of the sensing surface is small, and if it is blocked, it will also lead to inaccurate final measurement data. And the small sensing surface affects the measurement accuracy of the data and cannot well reflect the real data.

[0006] To achieve the above object, the present invention provides the following technical solutions: It includes a leaf sensing disc. Above the leaf sensing disc, a connecting sensing block is installed to perform temperature and humidity detection work on the contacted leaf through the connecting sensing block. On the upper surface of the leaf sensing disc, a clamping fixing plate is rotatably connected, and a leaf body is placed between the upper surface of the leaf sensing disc and the lower surface of the clamping fixing plate. Above the connecting sensing block, a detection auxiliary positioning mechanism for rotating the clamping fixing plate up and down is installed to improve the leaf detection range through the detection auxiliary positioning mechanism. The detection auxiliary positioning mechanism includes a rotating connecting rod, and a rotating fixing rod is installed inside the rotating connecting rod. On the back of the connecting sensing block, a semi-circular downward-sliding trigger rod is installed, and below the semi-circular downward-sliding trigger rod, an expansion sensing mechanism for ejecting an extended sensing disc is installed.

[0007] Further, the detection auxiliary positioning mechanism includes a rotating connecting rod, and a rotating fixing rod is installed inside the rotating connecting rod. The expansion sensing mechanism includes a transmission fixed ejecting rod, and the front end of the transmission fixed ejecting rod is fixedly installed on the lower surface of the extended sensing disc. A limiting extrusion inner groove is opened on the outer surface of the transmission fixed ejecting rod, and the limiting extrusion inner groove slides along the lower surface of the leaf sensing disc.

[0008] Further, a reset contact spring is installed on the lower surface of the connecting sensing block, and the front end of the reset contact spring contacts the outer surface of the transmission fixed ejecting rod. A traction fixing groove is opened at the end of the transmission fixed ejecting rod, and a second rotating inner groove is opened on the lower surface of the connecting sensing block.

[0009] Further, a rotating fitting rod is installed inside the second rotating inner groove, and a tip fitting head is installed at the front end of the rotating fitting rod. The tip fitting head and the traction fixing groove are nested and installed with each other. The front end of the tip fitting head is designed as a semi-circle, and a sliding downward pressure inner groove is opened on the outer surface of the semi-circular downward-sliding trigger rod.

[0010] Further, a limit fixing frame is installed on the back surface of the connection induction block, and the limit fixing frame is installed inside the sliding and pressing inner groove. The lower end of the semi-circular downward sliding trigger rod contacts the end of the rotating fitting rod, and the lower surface of the pressing transmission plate contacts the upper end of the semi-circular downward sliding trigger rod. Moreover, the upper end of the semi-circular downward sliding trigger rod is designed as a semi-circle.

[0011] Further, a first rotating inner groove is opened above the connection induction block, and a rotating fixing rod is fixedly installed inside the first rotating inner groove. A pressing transmission plate is installed at the right end of the rotating connecting rod, and a clamping fixing plate is installed on the lower surface of the rotating connecting rod. A top-out fixing spring is installed inside the first rotating inner groove. The upper end of the top-out fixing spring contacts the lower surface of the clamping fixing plate. Moreover, a blade body is installed on the back surface of the connection induction block. A semi-circular empty groove is opened on the upper surface of the pressing transmission plate, and the opening position of the pressing transmission plate corresponds to the installation position of the blade body.

[0012] Further, a docking and reset inner groove is opened on the lower surface of the blade sensing disc, and an extended induction disc is installed inside the docking and reset inner groove. A sliding extension inner groove is opened inside the extended induction disc, and the sliding extension inner groove slides along the lower surface of the blade sensing disc.

[0013] Further, the clamping fixing plate, the rotating connecting rod, and the pressing transmission plate are integrally designed, and the pressing transmission plate is rotatably installed inside the first rotating inner groove through the rotating fixing rod to rotate the clamping fixing plate upward.

[0014] Further, the lower end of the top-out fixing spring is fixedly installed inside the first rotating inner groove, and the upper surface of the top-out fixing spring contacts the lower surface of the rotating connecting rod to form an elastic structure. Moreover, the connection induction block and the blade sensing disc are designed with an internal connection.

[0015] Further, the two side surfaces of the extended induction disc contact the inner surface of the docking and reset inner groove to form a sliding structure, and the lower surface of the blade sensing disc contacts the inner surface of the sliding extension inner groove to form a sliding structure. Moreover, the extended induction disc is nested and installed inside the docking and reset inner groove.

[0016] Compared with the prior art, the beneficial effect of the present invention is: when the present invention needs to fix the blade temperature and humidity sensor, first press the downward transmission plate downward along the inside of the rotating inner groove. Since the downward transmission plate is rotated in the connecting sensing block by rotating the fixing rod, the downward transmission plate lifts the clamping fixing plate by rotating the connecting rod, and fits the lower part of the blade sensor disk to the blade body and places the blade body between the blade sensor disk and the clamping fixing plate. After releasing the downward transmission plate, the ejecting fixing spring will continuously squeeze the clamping fixing plate upward to achieve the fit between the blade sensor disk and the clamping fixing plate. This design enhances the sensing effect of the overall equipment. When the downward transmission plate is pressed downward, it contacts the semicircular downward trigger rod and slides downward against it. The semicircular downward trigger rod is driven to slide vertically due to the limiting operation of the limiting fixing frame and contacts the rotating interlocking rod. When the end of the rotating interlocking rod is contacted, the upper end is pushed upward, so the pointed interlocking head directly releases the traction fixing groove, causing the transmission fixed ejector rod and the extension sensor disk to be directly pushed forward by the reset spring without being fixed. This design makes the recovery and reset design of the extension sensor disk simpler and increases the sensing area of the equipment. When the extension sensor disk slides forward, it will be limited by the sliding extension inner groove to ensure horizontal sliding, and the sliding process is carried out inside the docking reset inner groove. When the extension sensor disk needs to be reset, the transmission fixed ejector rod is used to squeeze the reset spring, and then the front end of the pointed interlocking head is used to pass through the traction fixing groove to complete the interlocking and fixing operation of the extension sensor disk.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: Please refer to Figures 1-9 , the present invention provides the following technical solutions: a blade temperature and humidity sensor, including a blade sensing disc 1, a connecting induction block 5 is installed above the blade sensing disc 1, and the temperature and humidity detection of the contacted blade is carried out through the connecting induction block 5. A clamping fixing plate 2 is rotatably connected to the upper surface of the blade sensing disc 1, and a blade body 6 is placed between the upper surface of the blade sensing disc 1 and the lower surface of the clamping fixing plate 2. A detection auxiliary positioning mechanism for rotating the clamping fixing plate 2 up and down is installed above the connecting induction block 5, and the blade detection range is improved through the detection auxiliary positioning mechanism. The detection auxiliary positioning mechanism includes a rotating connecting rod 3, and a rotating fixed rod 18 is installed inside the rotating connecting rod 3. A semi-circular downward sliding trigger rod 14 is installed on the back of the connecting induction block 5, and an expansion sensing mechanism for ejecting the extension sensing disc 7 is installed below the semi-circular downward sliding trigger rod 14.

[0029] As Figure 1 , Figure 4 , [[ID=?]] Figure 5 , Figure 7 , Figure 9 It should be noted that there seems to be an incomplete or incorrect tag in the original text at line 24. It is marked as Figure 5 in the original but not fully translated in the above content as the original format is not clear. You may need to check and correct this part if necessary.The disclosed technical solution aims to solve the problem of insufficient stability in the fixed design of existing devices, and discloses that: a first rotating inner groove 16 is formed above the connecting induction block 5, and the rotating fixing rod 18 is fixedly installed inside the first rotating inner groove 16. The right end of the rotating connecting rod 3 is provided with a downward pressing transmission plate 4, and the lower surface of the rotating connecting rod 3 is provided with a clamping fixing plate 2. A top-out fixing spring 17 is installed inside the first rotating inner groove 16. The upper end of the top-out fixing spring 17 is in contact with the lower surface of the clamping fixing plate 2, and a blade body 6 is installed above the clamping fixing plate 2. A semi-circular empty groove is formed on the upper surface of the downward pressing transmission plate 4, and the fixing position of the clamping fixing plate 2 corresponds to the installation position of the blade body 6. A docking reset inner groove 19 is formed on the lower surface of the blade sensing disc 1, and an extended induction disc 7 is installed inside the docking reset inner groove 19. A sliding extension inner groove 8 is formed inside the extended induction disc 7, and the sliding extension inner groove 8 slides along the lower surface of the blade sensing disc 1. The clamping fixing plate 2, the rotating connecting rod 3, and the downward pressing transmission plate 4 are integrally designed, and the downward pressing transmission plate 4 is rotatably installed inside the first rotating inner groove 16 through the rotating fixing rod 18 to rotate the clamping fixing plate 2 upward. The lower end of the top-out fixing spring 17 is fixedly installed inside the first rotating inner groove 16, and the upper surface of the top-out fixing spring 17 is in contact with the lower surface of the rotating connecting rod 3 to form an elastic structure. Moreover, the connecting induction block 5 and the blade sensing disc 1 are designed with internal connection. The two side surfaces of the extended induction disc 7 are in contact with the inner surface of the docking reset inner groove 19 to form a sliding structure, and the lower surface of the blade sensing disc 1 is in contact with the inner surface of the sliding extension inner groove 8 to form a sliding structure. Moreover, the extended induction disc 7 is nested and installed inside the docking reset inner groove 19.

[0030] When it is necessary to perform the overall fixing operation on the blade temperature and humidity sensor, first press the pressing transmission plate 4 downward. Since the front end of the pressing transmission plate 4 is fixedly installed with the rotating connecting rod 3, and the lower end of the rotating connecting rod 3 is rotatably installed in the first rotating inner groove 16 through the rotating fixing rod 18, when the pressing transmission plate 4 is pressed downward to rotate downward, the rotating connecting rod 3 is lifted upward along the outside of the rotating fixing rod 18, and the front end of the rotating connecting rod 3 is also fixedly installed with the clamping fixing plate 2, so the clamping fixing plate 2 is synchronously rotated upward therewith. When the front end of the clamping fixing plate 2 is lifted upward, the lower surface will contact the ejection fixing spring 17 downward, since the end of the ejection fixing spring 17 is fixedly installed in the first rotating inner groove 16 opened on the upper surface of the connecting sensing block 5. The ejection fixing spring 17 is in contact with the lower surface of the clamping fixing plate 2 and will shrink vertically downward. When the clamping fixing plate 2 leaves the top of the blade sensor disk 1 that is in contact with it, the gap between the blade sensor disk 1 and the clamping fixing plate 2 is aligned with the blade to be fixed and then the downward pressing transmission plate 4 is directly released. The ejection fixing spring 17 will release the elastic potential energy and directly push the clamping fixing plate 2 upward, so that the upper surface of the blade sensor disk 1 and the lower surface of the clamping fixing plate 2 are tightly fitted to complete the fixation of the leaf surface or branch. When more accurate or more measurement data is needed, the extension sensing disk 7 can be extended by pulling the extension sensing disk 7 outward along the docking reset inner groove 19 opened inside the lower surface of the blade sensor disk 1, and the sliding extension inner groove 8 opened inside the extension sensing disk 7 will also ensure the stability of sliding.

[0031] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 8The technical solution shown, in order to solve the problem of inaccurate final results caused by insufficient sensing data when the equipment is working, discloses: the detection auxiliary positioning mechanism includes a rotating connecting rod 3, and a rotating fixed rod 18 is installed inside the rotating connecting rod 3, the expansion sensing mechanism includes a transmission fixed ejector rod 9, and the front end of the transmission fixed ejector rod 9 is fixedly installed on the lower surface of the extended sensing disk 7, the outer surface of the transmission fixed ejector rod 9 is provided with a limited extrusion inner groove 10, and the limited extrusion inner groove 10 slides along the lower surface of the blade sensor disk 1, the lower surface of the connecting sensing block 5 is provided with a reset resistance spring 11, and the front end of the reset resistance spring 11 resists the outer surface of the transmission fixed ejector rod 9, the end of the transmission fixed ejector rod 9 is provided with a traction fixed groove 13, and the lower surface of the connecting sensing block 5 is provided with a A second rotating inner groove 20 is provided, and a rotating interlocking rod 12 is installed inside the second rotating inner groove 20, and a pointed interlocking head 15 is installed at the front end of the rotating interlocking rod 12. The pointed interlocking head 15 and the traction fixing groove 13 are nested and installed with each other, and the front end of the pointed interlocking head 15 is semicircular in design. A semicircular downward sliding trigger rod 14 is installed on the back of the connecting sensing block 5, and the outer surface of the semicircular downward sliding trigger rod 14 is provided with a sliding downward pressing inner groove 22. A limited fixing frame 21 is installed on the back of the connecting sensing block 5, and the limited fixing frame 21 is installed inside the sliding downward pressing inner groove 22. The lower end of the semicircular downward sliding trigger rod 14 contacts the end of the rotating interlocking rod 12, and the lower surface of the downward pressing transmission plate 4 contacts the upper end of the semicircular downward sliding trigger rod 14, and the upper end of the semicircular downward sliding trigger rod 14 is semicircular in design.

[0032] When the downward pressing transmission plate 4 is pressed, the lower surface of the downward pressing transmission plate 4 will contact the upper end of the semicircular sliding trigger rod 14. Since the upper end of the semicircular sliding trigger rod 14 is semicircular in design, the semicircular sliding trigger rod 14 will be pushed downward, and the downward sliding of the semicircular sliding trigger rod 14 will proceed along the outside of the limit fixing frame 21 fixedly installed inside the connecting sensing block 5. The limit fixing frame 21 slides through the sliding downward pressing inner groove 22 opened at the corresponding position of the outer surface of the semicircular sliding trigger rod 14, and during the sliding process, the lower end of the semicircular sliding trigger rod 14 will contact the upper surface of the end of the rotating interlocking rod 12, and since the rotating interlocking rod 12 rotates inside the second rotating inner groove 20 opened at the corresponding position of the lower surface of the connecting sensing block 5, when the end of the rotating interlocking rod 12 is interfered, the front end of the rotating interlocking rod 12 will be correspondingly pushed upward, and since the front end of the rotating interlocking rod 12 is fixedly installed with the pointed interlocking head 15, the pointed interlocking head 15 rotates with When the movable interlocking rod 12 rotates upward, the tip interlocking head 15 will disengage from the traction fixing groove 13 opened in the corresponding position of the transmission fixed ejector rod 9 after the rotating interlocking rod 12 is disengaged from the traction fixing groove 13. After the rotating interlocking rod 12 is disengaged from the traction fixing groove 13, the transmission fixed ejector rod 9 is not restricted and fixed. At this time, the return resistance spring 11 fixedly installed on the lower surface of the connection sensing block 5 is squeezed by the transmission fixed ejector rod 9. At this time, the elastic potential energy is released to directly eject the transmission fixed ejector rod 9 forward, and the transmission fixed ejector rod 9 will slide forward on the lower surface of the blade sensor disc 1 through the limiting squeezing inner groove 10. At the same time, since the extension sensing disc 7 is fixedly mounted on the front end of the transmission fixed ejector rod 9, the extension sensing disc 7 slides synchronously with the forward sliding of the transmission fixed ejector rod 9, and the sliding extension inner groove 8 opened on the outer surface of the extension sensing disc 7 will perform a limiting operation along the outer side of the blade sensor disc 1, ensuring the sliding stability of the extension sensing disc 7 and the transmission fixed ejector rod 9.
