Description

[Technical field]

[0001] The present invention relates to a chlorophyll measuring device, and more particularly to a chlorophyll measuring device capable of fixing a clamping force. [Background technology]

[0002] Currently, the prior art describes a chlorophyll (chlorophyll) measuring meter that measures chlorophyll by manually pressing the meter. This chlorophyll measuring meter measures the chlorophyll content in an object to be measured (e.g., a plant) by sandwiching the object to be measured between a light-emitting diode pack (LED) part of a fixture and a light-receiving sensor.

[0003] Specifically, Chinese utility model application CN205879766U discloses a leaf clamping device of a one-piece elastic member with a U-shaped cross section, the device has a light-emitting end and a light-receiving end, the light-emitting end emits red and infrared light sources, the light-receiving end has a light-receiving sensor, black gaskets are arranged around the light-transmitting windows of the light-emitting end and the light-receiving end, and the chlorophyll content is measured by manually pressing the leaf clamp.Chinese utility model application CN203587493U discloses a dark-adapted leaf clamping device for succulent leaves, which has a high-density sponge ring, and the high-density sponge ring is black. Chinese invention patent application CN115356296A discloses a portable non-destructive testing device for the chlorophyll a, b content of leaves, which includes a leaf inspection module having a clamping table, a pressing piece, a control switch, a light source unit, and an illuminance sensor, and the light source unit can emit light sources of three wavelengths. When the pressing piece is pressed, the non-destructive testing device can measure the chlorophyll content, and the pressing piece can eliminate the influence of ambient light.

[0004] In addition, Chinese utility model application CN203376269U discloses a chlorophyll measuring device for landscaping work, which includes a camera bracket made of a bendable material and can be bent to allow the camera to take pictures from multiple angles. In addition, Chinese invention patent application CN115266601A discloses an apparatus for detecting chlorophyll content in living leaves of plants, which includes a distance measuring module, and the distance measuring module includes at least one distance measuring sensor for collecting distance data between the leaf to be measured.

[0005] However, the measurement results of the manual clamping structure have a problem that the measurement results are influenced by the difference in the pressure of the finger, resulting in unstable measurement accuracy. In addition, since most users are right-handed, many of the chlorophyll meters currently on the market are designed to fit right-handed people, which is inconvenient for left-handed users. Therefore, in the technical field of the present invention, there is a need for a chlorophyll measuring device that can clamp the measurement object (e.g., a leaf) with a constant force so as to reduce measurement errors caused by human operation, to suit both right-handed and left-handed users, and to reduce damage to the surface of the measurement object. Summary of the Invention

[0006] In view of the above problems, in order to solve the problems of the conventional chlorophyll measuring device, the present invention provides a chlorophyll measuring device including a measuring device main body, a clamping member, a first elastic member, and a second elastic member. The measuring device main body includes a first measuring part and a first pivoting part. The clamping member includes a second measuring part, a second pivoting part, and a pressing part. The pressing part is provided so as to be pressed by a force. The second pivoting part is elastically pivoted to the first pivoting part via the first elastic member. One of the first measuring part and the second measuring part has a light emitting part, and the other has a light receiving part, and the second elastic member is provided on the side of the measuring device main body facing the clamping member, or on the side of the clamping member facing the measuring device main body.

[0007] In a preferred embodiment, the measuring device body further includes a measurement start switch provided between the first pivot part and the first measuring part.

[0008] In a preferred embodiment, the measuring device body further includes a stopper, and when no external force is applied to the pressing portion, the first measuring portion and the second measuring portion have a first distance in the vertical direction, and the first distance is determined by the height of the stopper.

[0009] In a preferred embodiment, when no external force is applied to the pressing part, the chlorophyll measurement device is in a closed state, the light-emitting part and the light-receiving part have a first distance in the vertical direction, and the pressing part is parallel to the first measurement part. When pressure is applied to the pressing part, the chlorophyll measurement device is in an open state, the light-emitting part and the light-receiving part have a second distance in the vertical direction, and the second distance is larger than the first distance.

[0010] In a preferred embodiment, the second elastic member is provided around the outer periphery of the light receiving portion or the light emitting portion, and the second elastic member is curved outward in the horizontal direction to form a suction cup shape.

[0011] In a preferred embodiment, the first elastic member further includes a first extension portion provided on the measuring body and a second extension portion provided on the clamping member, the clamping member being positioned at an intermediate position of the chlorophyll measuring device, and the chlorophyll measuring device having an approximately symmetrical shape.

[0012] In a preferred embodiment, the chlorophyll measuring device is used to measure an object to be measured, and when the object to be measured is located between the first measuring part and the second measuring part and the chlorophyll measuring device is in a closed state, the second elastic member is arranged around the object to be measured so that the object to be measured does not escape from the area between the first measuring part and the second measuring part.

[0013] In a preferred embodiment, when the object to be measured is located between the first measurement unit and the second measurement unit and the chlorophyll measurement device is in a closed state, if the object to be measured exceeds the range in which the second elastic member can rotate, the second elastic member can deform to conform to the shape of the object to be measured and block external light.

[0014] In a preferred embodiment, the measuring device body further includes a display unit for displaying the measurement result.

[0015] In a preferred embodiment, the measuring device body further includes at least one port or at least one communication unit for connecting to an external device by wire or wirelessly.

[0016] In a preferred embodiment, the clamping member further includes a distance measuring portion, which is provided in the second measuring portion and is used to measure the distance between the distance measuring portion and an object to be measured.

[0017] In a preferred embodiment, the measuring device body further includes an imaging unit for photographing or recording the measuring object.

[0018] In a preferred embodiment, the meter body further includes a recording unit for recording sound.

[0019] Compared with the conventional technology, the chlorophyll measuring device of the present invention is easy to operate, and at the same time, the mechanism design between the clamping member and the measuring device body of the present invention can reduce measurement errors caused by differences in gripping and pushing strength when operating the device. In addition, the clamping member is located at approximately the center of the entire chlorophyll measuring device, so it can be used by both right-handed and left-handed users.

[0023] Please refer to Fig. 1, Fig. 2 and Fig. 4 together. Fig. 1 is a perspective view of a chlorophyll measuring device according to one embodiment of the present invention, Fig. 2 is a perspective cross-sectional view of a part of the chlorophyll measuring device according to one embodiment of the present invention in a closed state, and Fig. 4 is a perspective cross-sectional view of a part of the chlorophyll measuring device according to one embodiment of the present invention in an open state. The present invention provides a chlorophyll measuring device 10 including a measuring device main body 100, a clamping member 200, a first elastic member 103 and a second elastic member 203. The measuring device main body 100 includes a first measuring part 101 and a first pivoting part 102. The first measuring part 101 has a light receiving part 1011. The clamping member 200 includes a second measuring part 201, a second pivoting part 202 and a pressing part 204. The second pivoting part 202 is elastically pivoted to the first pivoting part 102 via the first elastic member 103. The pressing portion 204 is provided so as to be pressed by a force. The second measurement portion 201 has a light emitting portion 2011, and the second elastic member 203 is provided around the outside of the light emitting portion 2011.

[0024] Specifically, the light-emitting unit 2011 may include at least one light-emitting diode (LED) unit, and the light-emitting unit 2011 may emit light of different wavelengths through different LED members to measure a measurement object (e.g., a leaf, not shown). The wavelength may be a wavelength of visible light, a wavelength of infrared light, a wavelength of ultraviolet light, etc., and the present invention is not limited thereto, and may be adjusted according to actual needs. The light-receiving unit 1011 may be a photosensor or a photoresistor (Light-Dependent Resistor layer, LDR) for detecting attenuation of wavelength and intensity after the light source emitted from the light-emitting unit 2011 passes through a measurement object, thereby achieving the purpose of measuring the chlorophyll content.

[0025] In one embodiment, the clamping member 200 may further include a distance measuring unit 2012, which is provided in the second measuring unit 201 and is used to measure the distance between the distance measuring unit 2012 and the measurement object. The distance measuring unit 2012 may be disposed adjacent to the light emitting unit 2011 or may be disposed at a distance from the light emitting unit 2011, and the present invention is not limited thereto. Note that in the embodiments and drawings of the present invention, the light emitting unit 2011 (and / or the distance measuring unit 2012) is provided in the clamping member 200, and the light receiving unit 1011 is provided in the measuring device main body 100. In other embodiments, the positions of the light-emitting unit 2011 (and / or the distance measuring unit 2012) and the light-receiving unit 1011 may be adjusted relative to each other, i.e., the light-receiving unit 1011 may be provided in the clamping member 200, and the light-emitting unit 2011 (and / or the distance measuring unit 2012) may be provided in the measuring device main body 100.

[0026] In one embodiment, the measuring device main body 100 may further include a battery B (shown in FIG. 2), a receiving groove R, a display unit S, a measurement start switch SW2, and a power switch SW1. The battery B is used to provide the electric energy required for the chlorophyll measuring device 10, the receiving groove R is used to receive the pressing unit 204 when the pressing unit 204 is pressed down, and the display unit S is used to display the measurement result. The measurement start switch SW2 and the power switch SW1 are respectively used to switch on or off the entire power supply of the chlorophyll measuring device 10 to start the measurement of the chlorophyll measuring device 10. The measurement start switch SW2 is provided between the first pivoting part 102 and the first measuring part 101 so that the user can easily operate the switch while holding the chlorophyll measuring device 10. In other embodiments, the measurement start switch SW2 and the power switch SW1 may be provided at other positions on the measuring device main body 100, and the present invention is not limited thereto.

[0027] In one embodiment, the measuring device main body 100 may include a processing unit (not shown). The processing unit may include, for example, a processor (e.g., a CPU), a controller, and / or a board (e.g., a Printed Circuit Board, PCB) for processing measured data and electrical signals. The measuring device main body 100 may further include a sound recording unit and / or an image capturing unit (not shown) for providing a function of recording sound during measurement, or a function of photographing or recording the object to be measured. The measuring device main body 100 may also include at least one port and / or at least one communication unit (not shown) for connecting to an external device by wire and / or wirelessly and transmitting data to the external device. The at least one communication unit may transmit data via Bluetooth (registered trademark), a network, or other communication protocols, and the present invention is not limited thereto. As shown in FIG. 2 to FIG. 4, the measuring device main body 100 and the clamping member 200 may be electrically connected via an electric wire E so as to electrically connect the measuring device main body 100 and the member in the clamping member 200. In an embodiment of the present invention, the display unit, the at least one port, the at least one communication unit, the distance measurement unit 2012, the imaging unit and the sound recording unit are all optional, i.e., the chlorophyll measurement device 10 of the present invention may include at least one of the above components, and the present invention is not limited thereto.

[0028] The clamping member 200 is disposed at the middle position of the chlorophyll measurement device 10, and the chlorophyll measurement device 10 has a substantially symmetrical shape. This allows the chlorophyll measurement device 10 to be used favorably by both right-handed and left-handed users, and there is no need to change the design for users with different handedness.

[0029] Please refer to Figures 3, 5, 1, 2 and 4. Figure 3 is a perspective cross-sectional view of another part of the chlorophyll measurement device according to one embodiment of the present invention in a closed state, and Figure 5 is a perspective cross-sectional view of another part of the chlorophyll measurement device according to one embodiment of the present invention in an open state. The chlorophyll measurement device 10 of the present invention can be in a closed state and an open state, which will be described in detail below.

[0030] When no external force is applied to the pressing unit 204, the light receiving unit 1011 of the first measurement unit 101 and the light emitting unit 2011 of the second measurement unit 201 have a first distance D1 in the vertical direction, and at this time, the chlorophyll measurement device 10 is in the closed state, and when in the closed state, the pressing unit 204 is parallel to the first measurement unit 101. When pressure is applied to the pressing unit 204, the light receiving unit 1011 of the first measurement unit 101 and the light emitting unit 2011 of the second measurement unit 201 have a second distance D2 in the vertical direction, and the chlorophyll measurement device 10 is in the open state.

[0031] That is, the first interval D1 is smaller than the second interval D2. In one embodiment, the measuring device main body 100 further includes a stopper 104, and when no external force is applied to the pressing portion 204, the first interval D1 is determined by the height of the stopper 104. Specifically, the stopper 104 prevents the second measuring portion 201 from excessively pressing the measuring object by the elastic force of the first elastic member 103 by restricting the fall of the second measuring portion 201 and the second elastic member 203 in the vertical direction in the closed state. That is, regardless of whether the measuring object is present between the second measuring portion 201 of the clamping member 200 and the first measuring portion 101 of the measuring device main body 100, the first interval D1 is formed at equilibrium. This eliminates the need to manually apply force when clamping the measuring object, and makes it possible to avoid the influence of uneven force application on the measurement result.

[0032] In one embodiment, the first elastic member 103 may be composed of at least one spring, that is, the first elastic member 103 may be divisible or may have a plurality of sub-structures as long as the measuring device main body 100, i.e., the clamping member 200, can be elastically pivoted. The first elastic member 103 may be composed of other elastic bodies, and the present invention is not limited thereto. As shown in FIG. 2 and FIG. 4, the first elastic member 103 may further include a first extension portion 1031 provided on the measuring device main body 100 and a second extension portion 1032 provided on the clamping member 200. In this embodiment, the first elastic member 103 may include a spring as shown in the figure, and the first extension portion 1031 and the second extension portion 1032 formed by extending.

[0033] In one embodiment, the second elastic member 203 may be made of rubber, sponge, high molecular weight polymer, or other elastic body. The second elastic member 203 needs to be constantly in contact with the measurement object and the relatively precise members arranged in the first measuring unit 101 and the second measuring unit 201, and therefore the material hardness of the second elastic member 203 is less than the material hardness of the first elastic member 103. In an embodiment of the present invention, the second elastic member 203 may be a black high molecular weight polymer, and as shown in FIG. 5, the second elastic member 203 may have an annular shape, bend slightly outward in the horizontal direction to have a shape similar to a suction cup, and be provided around the light emitting unit 2011. However, the present invention does not limit the degree of bending or the specific shape of the second elastic member 203 as long as it is provided around the light emitting unit 2011.

[0034] In one embodiment, when the measurement object is located between the first measurement unit 101 and the second measurement unit 201 and the chlorophyll measurement device 10 is in the closed state, the second elastic member 203 is provided around the measurement object so that the measurement object does not escape from the region between the first measurement unit 101 and the second measurement unit 201. As shown in FIG. 3, when the device is in the closed state, the measurement object is limited to the sealed space formed between the second measurement unit 201, the second elastic member 203, and the first measurement unit 101, and is surrounded by the second elastic member 203, so that the measurement object can be prevented from going out of the measurement range. In addition, the second elastic member 203 can completely seal and block external light, so that the chlorophyll content can be measured more accurately.

[0035] In another embodiment, when the measurement object is located between the first measurement unit 101 and the second measurement unit 201 and the chlorophyll measurement device 10 is in the closed state, if the measurement object exceeds the range that the second elastic member 203 can rotate, the second elastic member 203 can deform along the shape of the measurement object to block external light. In practical application, the size of the measurement object is not necessarily completely surrounded by the second elastic member 203, but due to the elasticity of the second elastic member 203, the second elastic member 203 can deform along the shape of the measurement object to form a similar closed state and block external light, so that the chlorophyll content can be measured relatively accurately.

[0036] In practical application, a user holds the chlorophyll measuring device 10 of the present invention in his / her hand, presses the pressing portion 204 to open the chlorophyll measuring device 10, aligns the second measuring portion 201 of the clamping member 200 and the first measuring portion 101 of the measuring body 100 with the object to be measured, and then releases the pressed pressing portion 204 to close the chlorophyll measuring device 10 to clamp the object to be measured, for example, by clamping a plant leaf in the thickness direction to measure the chlorophyll content.

[0037] Thus, the chlorophyll measuring device 10 of the present invention is easy for the user to operate, and can reduce measurement errors caused by differences in the force applied to the measurement object due to differences in the gripping or pushing force used by the person operating it, by the design of the clamping mechanism between the clamping member 200 and the measuring device main body 100. Furthermore, since the clamping member 200 is located at approximately the center of the entire chlorophyll measuring device 10, it can be used suitably by both right-handed and left-handed users.

[0038] As shown in FIG. 4 and paragraph number 0031, the measuring device main body 100 further includes a stopper 104, which restricts the vertical drop of the second measuring part 201 and the second elastic member 203 in the closed state, thereby preventing the second measuring part 201 from excessively pressing the measurement object by the elastic force of the first elastic member 103. That is, the stopper 104 can effectively restrict the degree of pinching of the second measuring part 201 and the second elastic member 203 in the closed state. Then, when measuring a measurement object such as a thin leaf or something that is easily torn, it is possible to pinch the measurement object more accurately and at the same time without damaging the measurement object, and there is no need to avoid the relatively large leaf veins when using it.

[0039] The above are only preferred embodiments of the present invention, and those skilled in the art may make some improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
