Description

Technical Field

[0001] This utility model relates to the field of metal detection technology, and in particular to a metal foreign object detector for traditional Chinese medicine. Background Technology

[0002] Driven by economic interests, some expensive medicinal materials or those with volatile market prices, such as cordyceps, red ginseng, American ginseng, seahorse, and sea dragon, are adulterated with metal powder by unscrupulous merchants to increase their weight and obtain high profits. This harms consumers' interests, affects the accurate use of traditional Chinese medicine dosage, and seriously endangers the health of the people. The main methods of adulterating with metal to increase weight include adding similar-looking metal foreign objects into the medicinal materials and then using adhesives to bind them back to their original shape.

[0003] Because the metal powder mixed in exists inside the Chinese medicine and its appearance changes, it is easy to make a mistake when identified by the naked eye. It is necessary to take the sample back to the laboratory to destroy it or use chemical methods in conjunction with instrumental analysis to detect it. Not only can it not be detected on-site, but it also damages the valuable medicinal materials, causing waste and is not environmentally friendly. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] Because the metal powder mixed in is inside the Chinese medicine or because of the change in the appearance of the metal, it is easy to make a mistake by visual inspection. It is necessary to take the sample back to the laboratory to destroy it or use chemical methods and instruments to analyze it before it can be detected. It is impossible to detect it on the spot. In addition, it not only damages the valuable medicinal materials and causes waste, but it is also not environmentally friendly.

[0029] Therefore, this embodiment provides a Chinese medicine metal foreign object detector that is easy to carry, accurate and fast, and can detect medicinal materials on site.

[0030] Please see Figures 1-4 A metal foreign object detector for traditional Chinese medicine includes a housing 1, which is a hollow structure. A detection component and a buzzer 3 are installed inside the housing 1. Simply bring the detector close to or insert it into the medicinal material; if a metal foreign object is present in the material, the buzzer 3 will sound an alarm, providing a rapid response suitable for on-site detection. For example, the metal detector for traditional Chinese medicine provided in this embodiment can detect metal foreign objects larger than 0.5 mm, with accurate detection and sufficient ability to detect metal foreign objects present in traditional Chinese medicine.

[0031] Specifically, the housing 1 is divided into a handheld part 11 and a detection part 12. The housing 1 is rectangular in shape, with the handheld part 11 and the detection part 12 located at opposite ends of the length of the housing 1. This design allows the testing personnel to hold the handheld part 11 and bring the detection part 12 close to the medicinal material. After the medicinal material is bagged, the detection part 12 can also be inserted into the bag for easy testing.

[0032] Preferably, the detection component is disposed inside the detection part 12, and the thickness of the detection part 12 is less than the thickness of the handheld part 11, so that the detection component is closer to the medicinal material and the detection accuracy is improved. More preferably, at least one side of the detection part 12 in the thickness direction is lower than that of the handheld part 11.

[0033] In this embodiment, please refer to Figure 3 One side of the detection part 12 is recessed so that the side is lower than the handheld part 11. In other feasible embodiments, both sides of the detection part 12 can also be recessed so that both sides of the detection part 12 in the thickness direction are lower than the handheld part 11.

[0034] For example, the length of the housing 1 is 18-20mm, the width of the housing 1 is 5-8mm, the thickness of the handheld part 11 is 3-4mm, the thickness of the detection part 12 is 2-3mm, and the length of the handheld part 11 and the length of the detection part 12 are designed according to actual needs and are not specifically limited here.

[0035] Furthermore, the buzzer 3 is installed inside the handheld part 11, without occupying the internal space of the detection part 12, thus reserving sufficient installation space for the detection components.

[0036] Accordingly, in this embodiment, a plurality of loudspeaker holes 111 are provided on the back of the handheld part 11. The plurality of loudspeaker holes 111 are centrally located and all communicate with the internal space of the handheld part 11. Furthermore, the loudspeaker holes 111 are directly facing the buzzer 3. The sound of the buzzer 3 can be directly transmitted through the loudspeaker holes 111 without being blocked by the housing 1, thereby increasing the sound volume to ensure effective alarm.

[0037] Preferably, the inner wall of the handheld part 11 is provided with a filter screen with a small pore size to prevent external dust or debris from entering the interior of the handheld part 11 through the sound amplification hole 111, thus preventing it from affecting normal testing.

[0038] Furthermore, a battery 112 is also installed inside the handheld part 11. The buzzer 3 and the detection component are both connected to the battery 112. The battery 112 is used to power the buzzer 3 and the detection component to complete the detection. Correspondingly, a battery 112 cover is also provided on the front of the handheld part 11. The battery 112 cover is fastened to the handheld part 11, and the battery 112 cover can be opened to install or remove the battery 112.

[0039] Furthermore, a detection switch 13 is mounted on the side wall of the housing 1. The detection switch 13 is used to connect or disconnect the power supply circuit of the battery 112. Pressing the detection switch 13 pops it out, connecting the power supply circuit, and the battery 112 supplies power to the detection component and the buzzer 3 to start the detection. Pressing the detection switch 13 back in disconnects the power supply circuit to turn off the detection. With the above settings, in the idle state, the detection switch 13 is in the pressed-in state, thereby avoiding accidental activation.

[0040] Optionally, an indicator light 14 is provided on the housing 1. The indicator light 14 is connected to the battery 112. Pressing the detection switch 13 pops it out and the indicator light 14 lights up. Pressing the detection switch 13 again pops it in and the indicator light 14 turns off.

[0041] Please see Figure 4 In this embodiment, the detection component includes an oscillator 21, a transmitting coil 22, and an induction coil 23. The oscillator 21 is connected to the battery 112 and is used to generate a high-frequency AC signal. The transmitting coil 22 is connected to the oscillator 21, receives the high-frequency current from the oscillator 21, and generates an alternating magnetic field around it. The induction coil 23 senses any changes in the alternating magnetic field generated by the transmitting coil 22.

[0042] Specifically, there are two induction coils 23, which are located on both sides of the transmitting coil 22. The two induction coils 23 are wound in opposite directions. In the absence of metal interference, the output signals of the two induction coils 23 cancel each other out. When a metal foreign object enters the magnetic field region generated by the transmitting coil 22, it will change the local magnetic field characteristics, such as the magnetic flux density and distribution, which will cause the voltages induced by the two induction coils 23 to no longer be exactly the same, thus breaking the original balance state.

[0043] For example, both induction coils 23 are coaxially arranged with the transmitting coil 22, and both are silver-plated coils, which can more sensitively sense changes in the magnetic field.

[0044] Furthermore, the detection component also includes a differential amplifier 24, which is connected in parallel between the two induction coils 23. The differential amplifier 24 is capable of receiving and amplifying the induced voltage difference between the two induction coils 23 for subsequent processing.

[0045] Furthermore, the detection component also includes a control unit. The control unit has a preset threshold and can receive and analyze the voltage difference signal amplified by the differential amplifier 24. When the analysis result is higher than the set threshold, the buzzer 3 is controlled to sound an alarm, indicating the presence of a metallic foreign object.

[0046] The detection component also includes a circuit board, on which the control unit is integrated. The circuit board is equipped with a transmission interface and a sensing interface. The transmission coil 22 and the oscillator 21 are both connected to the transmission interface, and the sensing coil 23 and the differential amplifier 24 are both connected to the sensing interface, ensuring reliable operation in various environments.

[0047] This embodiment provides a traditional Chinese medicine metal foreign object detector that can detect medicinal materials on-site. After pressing the pop-out detection switch 13, the testing personnel only need to hold the handheld part 11 and bring the detection part 12 close to or insert it into the medicinal material. If there is a metal foreign object in the medicinal material, the buzzer 3 will sound an alarm. The response is rapid. In addition, the thickness of the detection part 12 is less than the thickness of the handheld part 11, so that the two induction coils 23 in the detection component are closer to the medicinal material, thereby improving the accuracy of detection.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
