[0031] 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.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides a handheld tobacco leaf counter, comprising:

[0034] The housing 1 has a receiving cavity, a scanning window and a display window, wherein the scanning window and the display window are connected to the interior of the receiving cavity;

[0035] A circuit board is arranged in the accommodating cavity, and a processor is arranged on the circuit board;

[0038] A camera is disposed in the accommodating cavity and electrically connected to the circuit board;

[0039] A power supply component is disposed in the accommodating cavity and electrically connected to the circuit board, and is used to supply power to the circuit board;

[0040] There are multiple adjustment buttons 4, all of which are arranged on the first side surface of the housing 1, and the adjustment buttons 4 are connected to the circuit board;

[0041] A handle 5 is provided on the second side surface of the housing 1;

[0042] The scan button 6 is provided on the handle 5 and connected to the circuit board.

[0043] In this embodiment, a handheld tobacco leaf counter includes a housing 1, a circuit board, a processor, a display screen 2, a scanning screen 3, a camera, a power supply assembly, an adjustment button 4, a handle 5, and a scanning button 6. The housing 1 has a housing, a scanning window, and a display window. The scanning screen 3 is disposed on the scanning window, the display screen 2 is disposed on the display window, the circuit board is disposed within the housing, the processor is disposed on the circuit board, and the camera is disposed within the housing and electrically connected to the circuit board. The camera is used to capture the shape of the object facing the scanning screen 3. When the processor stores the shape of a leaf, the image captured by the camera can be transmitted to the processor for processing. The processed image can be used to identify the number of leaves. The power supply assembly is disposed within the housing and is used to power various electrical components. The adjustment button 4 is disposed on the housing 1 and is used to select a program within the processor. The scanning button 6 is disposed on the handle 5. During scanning, the scanning button 6 needs to be pressed for a long time. Once the scan is completed, the scanning button 6 can be lifted. During use, not only the tobacco leaves but also the tobacco stems are scanned. The position of the leaves on the stems is fixed. Therefore, even if the tobacco is scanned from multiple angles, the same leaf will not be counted repeatedly, thereby determining the accurate number of tobacco leaves. The handheld tobacco leaf counter provided by the utility model can accurately determine the number of tobacco leaves, save time and labor, and provide great assistance to scientific researchers in counting the number of tobacco leaves.

[0044] The handheld tobacco leaf counter provided by the utility model sets a tobacco leaf quantity alarm program in the processor, that is, a program is input into the processor, and this program includes a counting function. When the number of scanned leaves reaches a threshold, the handheld tobacco leaf counter will prompt the operator so that the operator does not need to scan again, thereby improving the efficiency of leaf scanning and allowing the operator to quickly remove excess tobacco leaves.

[0045] It should be noted that when the handheld tobacco leaf counter provided by the present invention scans and counts tobacco, it is necessary to scan from multiple angles from top to bottom or from bottom to top, so as to ensure the accuracy of the number of leaves scanned.

[0046] The power supply component can be a detachable battery or a rechargeable battery. When the power supply component is a rechargeable battery, the housing 1 is further provided with a charging interface, which is electrically connected to the power supply component.

[0047] It should be noted that the counter provided by the present invention is generally similar to the common scanner structure on the market. By changing the sensor in the scanner into a camera and then adding a battery, a handheld tobacco leaf counter in the present invention can be formed. The processor stores a set image recognition program.

[0048] Example 2

[0049] like Figures 2 and 3 As shown, based on the first embodiment, the handheld tobacco leaf counter further includes a dehumidification component, which includes:

[0050] A connecting ring 7 is sleeved on the housing 1 and is close to the scanning end of the housing 1;

[0051] A driving member 8 is provided on the connecting ring 7 and has a driving end with rotational freedom;

[0052] The end of the rocker 9 is connected to the driving end of the driving member 8, and the rocker 9 is swung and rotated by the driving member 8;

[0053] The water absorbing member 10 is provided on the rocking rod 9 , and the water absorbing member 10 cleans the scanning screen 3 by means of the swing of the rocking rod 9 .

[0054] During daily use, once dew drops are on the tobacco leaves, it will be found in the actual operation process that the counter will be scratched against the leaves, resulting in water droplets on the scanning screen 3, which will affect the scanning effect of the camera. Although the water droplets on the scanning screen 3 can be wiped manually, it requires people to operate from time to time. Once the operation is improper, it will still affect the scanning of the tobacco leaves. Therefore, it is necessary to adopt an automated method to solve the above problem. In this embodiment, the dehumidification component includes a connecting ring 7, a driving member 8, a rocker 9 and a water absorbing member 10.

[0055] The connecting ring 7 is sleeved on the exterior of the housing 1, and the driving member 8 is fixedly connected to the connecting ring 7. The driving member 8 is typically a motor, the output end of which is connected to the end of a rocker 9. The end of the rocker 9 for connecting to the driving member 8 has a ring-shaped structure. The output end of the motor and the rocker 9 are keyed and have an interference fit, thereby preventing the rocker 9 from being thrown off the output shaft of the motor during the swinging process. The absorbent member 10 can be a common strip of absorbent paper or absorbent cotton. Driven by the rocker 9, the absorbent member 10 can wipe the scanning screen 3 to remove water droplets or water marks on the surface of the scanning screen 3.

[0056] It should be noted that the rocker 9 can be in a reciprocating swinging form or a full rotation form. In order to further reduce the difficulty of operation, a program can be set in advance in the processor, and after performing N scans, the driving member 8 will drive the rocker 9 to move.

[0057] Further, if Figures 2 and 3As shown, this embodiment proposes that a threaded hole is opened on the connecting ring 7, and the threaded hole passes through the outside of the connecting ring 7 to the inside of the connecting ring 7. The dehumidification component also includes a connecting bolt 11, and the connecting bolt 11 is passed through the threaded hole.

[0058] In this embodiment, since the connection between the connecting ring 7 and the housing 1 is detachable, to prevent the connecting ring 7 from falling off the housing 1 during normal operation, a threaded hole is provided in the connecting ring 7, through which a connecting bolt 11 is passed. When the connecting ring 7 is mounted on the exterior of the housing 1, the ends of the connecting bolt 11 abut against the housing 1. Since the two connecting bolts 11 are symmetrically arranged, this increases the friction between the connecting ring 7 and the housing 1.

[0059] Manufacturing method of the connecting ring 7: The connecting ring 7 can be manufactured by 3D printing. First, the counter is scanned and an image is generated. Then, a contoured connecting ring 7 is produced in the software, and then the connecting ring 7 is manufactured by a 3D printer.

[0060] Further, if Figures 2 and 3 As shown, this embodiment proposes that the dehumidification assembly further includes a protective cover 12 , which is sleeved on the outside of the driving member 8 and is used to protect the driving member 8 .

[0061] In this embodiment, when the driving component 8 is a motor, the motor needs to be protected to a certain extent to prevent water from entering the motor and causing obstacles during scanning. A protective cover 12 is provided on the outside of the motor. The protective cover 12 is directly mounted on the outside of the motor. Air holes are provided on the protective cover 12 for heat dissipation of the motor.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
