Description

Technical Field

[0001] This utility model relates to the field of spectral analysis devices, specifically to a rotating sample cup device with water-proof properties. Background Technology

[0002] Near-infrared spectroscopy analyzers are advanced instruments that utilize near-infrared light for rapid, non-destructive testing of analytes, widely used in food, agriculture, pharmaceuticals, and chemicals. Their core technology involves analyzing the absorption and reflection characteristics of samples using near-infrared spectroscopy to obtain information about the sample's chemical composition or physical properties, such as moisture content and component ratios. These devices are typically equipped with rotating sample cups to achieve multi-angle sampling, thereby improving the uniformity and accuracy of the detection and making the results more reliable. In practical applications, users place liquid, powder, or solid samples in the sample cup. The device emits a beam of light from a near-infrared light source that penetrates or reflects the sample, and receives the signal through a spectral sensor. The internal processing unit then analyzes the data and generates a test report.

[0003] Existing near-infrared spectroscopy analysis devices have revealed the following comprehensive problems in practical use: First, insufficient protective design of the device allows liquids or particles to seep into the instrument during sample loading, damaging optical and electronic components and significantly reducing the reliability and service life of the equipment; Second, mechanical vibration and abnormal noise during operation can interfere with spectral signal acquisition, directly affecting the stability and accuracy of the detection results.

[0021] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0022] To better illustrate this embodiment, some parts in the accompanying drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions;

[0023] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] This embodiment proposes a rotating sample cup device with water-proof effect, such as... Figure 1 The diagram shown is a schematic representation of the rotating sample cup device with water-proof effect according to this utility model.

[0027] This embodiment proposes a rotating sample cup device with water-proof effect, including a drive module, a rotating mechanism, a turntable 1, a base 2, and a sample cup 3; the turntable 1 is located above the base 2, the rotating mechanism passes through the base 2 and is connected to the turntable 1, and the sample cup 3 is placed above the turntable 1; the drive module drives the turntable 1 to rotate on a horizontal plane through the rotating mechanism; a sealing assembly is provided between the base 2 and the turntable 1.

[0028] In this embodiment, the drive module drives the turntable 1 to rotate on a horizontal plane via the rotating mechanism. The sealing component between the base 2 and the turntable 1 prevents external moisture or dust from entering, significantly improving the device's protective performance and greatly extending its service life. It also prevents liquid samples from spilling and damaging the instrument during loading. Furthermore, the sealing component design also provides shock absorption and noise reduction, decreasing friction and noise during rotation, thereby improving the device's operational stability.

[0029] In an alternative embodiment, the sealing assembly includes a groove 4 on the upper surface of the base 2 and a seal 5 embedded in the groove 4.

[0030] like Figure 2 The image shown is a magnified view of a portion of the sealing assembly.

[0031] In this embodiment, the sealing element 5 is tightly embedded in the groove 4 on the upper surface of the base 2, forming a highly fitted sealing structure, thereby effectively preventing external moisture, dust or other particles from entering the device. In addition, by setting the groove 4 to accommodate the sealing element 5, the sealing element is fixed and positioned, and no additional bonding or complicated operation is required during installation, reducing maintenance difficulty and usage cost.

[0032] In an alternative embodiment, the seal 5 comprises a rubber or polymer material.

[0033] In this embodiment, the rubber and polymer materials possess excellent flexibility and resilience, enabling them to fit tightly against the contact surfaces of the base 2 and the turntable 1 in the slot 4, thereby forming a highly reliable sealing effect and effectively preventing the infiltration of external moisture, dust, or other particles. In addition, the rubber and polymer materials typically have good wear resistance, maintaining the integrity and functionality of the seal while the turntable 1 rotates for extended periods, extending the service life of the sealing components, reducing replacement frequency and maintenance costs, and absorbing the mechanical stress generated by the rotation of the turntable 1 or external vibrations, thus playing a role in shock absorption and buffering, further enhancing the reliability and durability of the equipment.

[0034] Example 2

[0035] This embodiment is an improvement upon the rotating sample cup device with water-proof effect proposed in Embodiment 1.

[0036] This embodiment proposes a rotating sample cup device with water-proof effect, including a drive module, a rotating mechanism, a turntable 1, a base 2, and a sample cup 3; the turntable 1 is located above the base 2, the rotating mechanism passes through the base 2 and is connected to the turntable 1, and the sample cup 3 is placed above the turntable 1; the drive module drives the turntable 1 to rotate on a horizontal plane through the rotating mechanism; a sealing assembly is provided between the base 2 and the turntable 1.

[0037] In an optional embodiment, the turntable 1 is provided with a first magnet 6, and the sample cup 3 is provided with a magnet corresponding to the first magnet 6.

[0038] In this embodiment, the first magnet 6 is attracted to the magnet of the sample cup 3, and the magnetic attraction achieves precise positioning of the sample cup 3, improving the ease of operation of the device and the accuracy of sample processing. At the same time, when the device rotates, the magnetic attraction structure provides additional fixing force, so that the sample cup remains stable even when rotating at high speed or affected by external forces, avoiding shaking or displacement, thereby ensuring the consistency and reliability of sample processing during experiments or operations.

[0039] In one optional embodiment, the driving device includes a motor 7 and a synchronous belt drive assembly 8; the output end of the motor 7 is connected to the rotating mechanism via the synchronous belt drive assembly 8.

[0040] In this embodiment, the synchronous belt drive assembly 8 is driven by the motor 7, thereby driving the rotating mechanism to rotate. The synchronous belt drive assembly 8 features smooth transmission and low noise. It can effectively isolate the vibration generated during motor operation, preventing the vibration from being directly transmitted to the turntable 1, thus ensuring that the sample cup maintains stable operation during rotation and preventing errors in the detection results caused by vibration interference.

[0041] In an optional embodiment, the rotating mechanism includes a rotating shaft 9, the driving end of which is connected to the synchronous belt drive assembly 8, and the driven end of which is fixedly connected to the turntable 1.

[0042] In this embodiment, the rotating shaft 9 drives the turntable 1 to rotate, and the driving power of the rotating shaft 9 can be smoothly and efficiently transmitted to the turntable 1, ensuring the rotational accuracy and stability of the turntable, thereby meeting the requirements of high-precision sample processing. At the same time, the design of the rotating shaft 9 further improves the operating efficiency of the device.

[0043] Alternatively, the rotating mechanism may further include a bearing 10 disposed between the rotating shaft and the base 2.

[0044] Specifically, the bearing 10 is fixed to the base 2 by the bearing fixing bracket 14.

[0045] In this embodiment, the bearing 10 provides support and rotation, enabling the rotating shaft to maintain stable and smooth rotation during operation, effectively reducing frictional resistance and improving the rotational efficiency of the turntable 1. Simultaneously, the bearing design significantly reduces mechanical noise during operation, achieving quiet operation.

[0047] This embodiment is an improvement upon the rotating sample cup device with water-proof effect proposed in Embodiments 1 and 2.

[0048] This embodiment proposes a rotating sample cup device with water-proof effect, including a drive module, a rotating mechanism, a turntable 1, a base 2, and a sample cup 3; the turntable 1 is located above the base 2, the rotating mechanism passes through the base 2 and is connected to the turntable 1, and the sample cup 3 is placed above the turntable 1; the drive module drives the turntable 1 to rotate on a horizontal plane through the rotating mechanism; a sealing assembly is provided between the base 2 and the turntable 1.

[0049] In an optional embodiment, the rotating sample cup device is further provided with a rotation speed detection device and a controller; the output end of the rotation speed detection device is connected to the input end of the controller, and the output end of the controller is connected to the input end of the drive module.

[0050] In this embodiment, the rotational speed of turntable 1 is detected in real time by a speed detection device, and the detected data is transmitted to the controller. The controller dynamically adjusts the power of the drive module according to preset speed parameters, thereby achieving stepless adjustment of the turntable speed. Through real-time monitoring and precise adjustment, the turntable can always be kept within the set speed range, ensuring the stability of sample processing and the accuracy of experimental results. In addition, the stepless speed regulation function can adapt to the needs of different sample processing or experimental operations, providing greater flexibility and adaptability, while avoiding equipment damage or errors caused by excessive speed fluctuations.

[0051] In an optional embodiment, the rotation speed detection device includes a magnetic sensor 11 and a second magnet 12; the magnetic sensor 11 is fixed to the lower surface of the base 2, and the second magnet 12 is disposed at a non-center position on the turntable 1.

[0052] In this embodiment, the magnetic sensor 11 generates a signal when the second magnet 12 rotates with the turntable, which can accurately detect the real-time rotation speed of the turntable, ensuring the stability and accuracy of data acquisition. Since the detection between the magnetic sensor and the second magnet is non-contact, the wear and noise problems of traditional mechanical detection methods are avoided, while improving the service life of the device and the quietness of its operation.

[0053] In an alternative embodiment, the drive module is fixed below the base 2 by a fastener 13.

[0054] In this embodiment, the stability of the drive module is ensured by the fastener 13, and liquid seepage into the drive module is also prevented from causing damage.
