Description

Technical Field

[0001] This utility model relates to the field of precious metal element detection technology, specifically to a portable benchtop gold purity analyzer. Background Technology

[0002] Currently, gold purity testing mainly relies on traditional precious metal analyzers. These devices typically employ X-ray fluorescence spectrometry (XRF) for analysis. This method has advantages such as ease of operation, fast analysis speed, and no sample destruction. It estimates the elemental content in a sample by measuring the characteristic X-rays emitted after the sample is irradiated with X-rays. It is commonly used as a preliminary screening and rapid analysis method for precious metal ore samples.

[0003] However, existing precious metal detectors are generally complex in structure, bulky, heavy, and energy-intensive, and require external power supplies, displays, and main units, making them inconvenient to operate in the field. The bulkiness of the equipment and its dependence on external devices limit their application in field operations, on-site testing, and mobile environments, failing to meet users' needs for convenient and efficient precious metal detection.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Depend on Figures 1 to 3 As shown in the figure, this utility model embodiment provides a portable benchtop gold purity analyzer, which includes a chassis assembly, a cover assembly 200, a detection assembly 300, an interaction assembly, and a battery assembly 400.

[0034] The chassis assembly has a first cavity.

[0035] The hatch assembly 200 is openably and closably engaged with the chassis assembly. A second cavity is formed between the hatch assembly 200 and the chassis assembly.

[0036] The detection assembly 300 includes a detection system 302 located in the first cavity and a sample stage 301 located at least partially in the second cavity. The sample stage 301 is configured to hold a sample and allow X-rays emitted by the detection system 302 to irradiate the sample to detect the purity of gold. Preferably, the detection system 302 is an X-ray fluorescence spectrometer. The sample stage 301 is a thin plate or film made of materials such as diamond, beryllium, aluminum, titanium, vanadium, polyimide film, polyethylene (PE), polyester film (PET), polypropylene (PP), or polycarbonate (PC). X-ray fluorescence spectrometers are existing technology and will not be described further in this invention.

[0037] An interactive component is electrically connected to the detection system 302. The interactive component is configured to control the detection system 302 and display the detection results.

[0038] The battery assembly 400 is located in the first cavity and is electrically connected to the detection system 302 and the interaction component. Preferably, the battery assembly 400 is designed to be detachable, and a switch is provided on the battery assembly 400. Pushing the switch opens the flip cover, allowing the battery to be removed for easy maintenance.

[0039] In existing technologies, gold purity testing equipment generally suffers from being bulky and complex to operate. Traditional benchtop analytical instruments typically rely on a fixed power supply, which cannot meet the needs of rapid on-site testing. Some devices employ an open testing area design, posing a risk of radiation leakage, and the frequent contact between operators and samples leads to low testing efficiency. For example, in jewelry appraisal scenarios, appraisers must send samples to a laboratory for testing, and the inability to obtain results in real time affects transaction efficiency.

[0040] To address these issues, the R&D team discovered that the core limitations to portability lay in the power supply method and structural integration. Analysis revealed that integrating the detection system 302 with the user interface could reduce the device's size, and adopting a flip-up hatch structure could simultaneously resolve the conflict between radiation protection and ease of operation. After multiple structural simulation tests, it was ultimately determined that the detection area and control system would be arranged in a layered layout, utilizing a hinged hatch to achieve a safe and enclosed detection space.

[0041] Specifically, the internal space of the chassis is divided into a detection area and an equipment area. The detection system 302 is installed at the bottom of the first cavity and emits X-rays vertically upwards to penetrate the sample stage 301. When the cover is closed, the sample stage 301 is completely enclosed in the second cavity, preventing operators from coming into contact with the radiation source. The touch screen 602 is stored in a recessed area at the front of the chassis via a folding structure, unfolding to form a tilted operating interface during operation. The battery pack is located on the side wall of the equipment area and provides uninterrupted power supply via a quick-release interface. During detection, simply open the cover to place the sample; after closing it, the touch screen 602 automatically wakes up and enters the detection interface; the entire process requires no external equipment.

[0042] Compared to existing technologies, traditional testing equipment requires a separate radiation shielding room. This solution integrates radiation protection with the equipment through an integrated canopy structure. Most portable devices on the market use external displays; this solution's foldable touchscreen 602 significantly reduces storage volume while maintaining a usable operating area. Most mobile testing instruments rely on AC power; this solution's built-in battery pack supports continuous operation for over four hours, adapting to environments without power.

[0043] Through the above technical solutions, this application achieves convenient operation of the detection chamber with one hand, reducing the detection preparation time to less than ten seconds. The foldable interactive interface reduces the equipment's transport volume by 40%. The enclosed detection chamber reduces the radiation dose in the working environment to below the safe threshold, eliminating the need for dedicated protective equipment. The modular battery design supports hot-swappable replacement, ensuring continuous detection work during field operations.

[0044] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the interactive component includes a controller 601 electrically connected to the detection system 302 and the battery assembly 400, and a touch screen 602 electrically connected to the controller 601. The chassis assembly is provided with a first recess to accommodate the touch screen 602. The touch screen 602 is hinged to the first recess and configured to switch between a retracted state embedded in the first recess and an operational state extending outward from the first recess.

[0045] The controller 601 provides stable computing power for the entire system. The detection component 300 is located in the middle of the first cavity, and the battery component 400 and controller 601 are respectively located on both sides of the detection component 300. The controller 601 is an integrated circuit module used to receive detection data and control the operation of the detection system 302. Specifically, it can be implemented using an embedded microprocessor. It is connected to the touch screen 602 and the detection system 302 through a circuit board and plays the role of data processing and instruction transmission.

[0046] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the touch screen 602 is hinged to the first groove near the bottom via a damping hinge, and is configured such that the side with the screen faces the chassis assembly when in the retracted state, and can be rotated and hovered for touch control at any angle from 0 to 180 degrees. The damping hinge is located at the lower front of the main chassis 101.

[0047] The chassis assembly also includes a first limiting buckle 105 for confining the touchscreen 602 to a storage position. The chassis assembly also includes a first hand groove communicating with the first recess, allowing the touchscreen 602 to be opened from the first recess. Preferably, the first latch 207 is a sliding limiting buckle, capable of switching between a limiting position and a limiting position by sliding.

[0048] When folded, the touchscreen 602 is fully embedded in the first recess, with the screen surface facing inwards and the outer casing facing outwards, preventing scratches during transport. When needed, the touchscreen 602 is pulled outwards using the handle slot, rotating around the bottom hinge to unfold to its working angle. The damping hinge provides moderate rotational resistance, allowing the touchscreen 602 to hover at any angle, facilitating viewing angle adjustments for users of different heights. In operation, the touchscreen 602 and the chassis form an inclined support structure, allowing the operator to directly touch the screen to set parameters and read test results. After operation, the touchscreen 602 is rotated in the opposite direction until fully embedded in the first recess, at which point the first limit latch 105 automatically engages to prevent accidental opening.

[0049] Compared to existing technologies, traditional gold analyzers typically use fixed external displays or simple flip-top structures, which suffer from issues such as easily damaged screens and inconvenient viewing angle adjustments. This solution combines a bottom-hinged touchscreen 602 with a recessed storage structure, achieving complete screen protection while providing multi-angle hovering functionality. Compared to the top hinge design of conventional folding screen devices, the bottom hinge brings the center of gravity closer to the body when the screen is unfolded, enhancing operational stability. The precise fit between the first recess and the touchscreen 602 significantly reduces the risk of collision damage during transportation compared to traditional exposed screen designs.

[0050] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the cover assembly 200 includes a sample compartment cover 201 hinged to the chassis assembly, and a first latch 207 disposed on the sample compartment cover 201. The chassis assembly is provided with an opening button 104. The opening button 104 is configured to engage the first latch 207 when the sample compartment cover 201 is closed to the chassis assembly, and is configured to release the first latch 207 when subjected to external force.

[0051] The first latch 207 refers to a mechanical locking structure fixed to the front end of the sample chamber cover 201. It can be implemented using a spring pin or magnetic fastener and is used to lock in conjunction with the opening button 104. The opening button 104 is a push-button unlocking mechanism located on the front of the chassis assembly. It can be a structure where an elastic reset button engages with a slot. External force triggers the unlocking action, releasing the first latch 207 to open the cover. When the sample chamber cover 201 is closed, the first latch 207 and the opening button 104 engage physically, keeping the button in an unpressed state and the latch fixed and unable to move, thus maintaining the cover closed. When the cover needs to be opened, the operator presses the opening button 104. The internal elastic element of the button deforms, releasing the limiting effect on the first latch 207. The latch then disengages from the engagement area along the hinge rotation trajectory of the sample chamber cover 201, allowing the cover to open smoothly. During this process, the position of the hinge's rotation axis is optimized to ensure a uniform torque distribution during the opening action, thus avoiding structural deformation caused by unilateral force.

[0052] Compared to existing technologies, traditional benchtop analyzers often employ a separate design with external hinges and independent latches, resulting in bulky locking mechanisms and complex operation. This solution integrates the latch and button onto the hatch's closing contact surface, achieving locking directly through mechanical interference. This eliminates the need for additional locks or electromagnetic devices, simplifying the structure while improving locking reliability. Furthermore, traditional equipment often suffers from X-ray leakage due to latch misalignment. This solution, through precise snap-fit ​​fitting, ensures that the gap between the hatch and the chassis components is less than a safe threshold when closed.

[0053] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 and Figure 2 As shown, one of the sample chamber cover 201 and the chassis assembly is provided with a locking knob. The other of the sample chamber cover 201 and the chassis assembly is provided with a locking hole adapted to the locking knob. The locking knob is constructed to be able to be inserted into the locking hole by rotation or sliding to limit the sample chamber cover 201 to a closed state.

[0054] A locking twist is a mechanical locking component with a raised structure, which can be implemented using a metal part with a rotating latch, and its raised part matches the shape of the lock hole. A lock hole is a groove structure that physically engages with the locking twist, which can be implemented using a machined through hole or blind hole, and its dimensions form a clearance fit or interference fit with the raised part of the locking twist. The locking twists are installed on both sides of the sample chamber cover 201, and the lock holes are correspondingly located on the inner wall area of ​​the chassis assembly. When the sample chamber cover 201 is closed, the raised part of the locking twist can be rotated 90 degrees clockwise to engage with the lock hole, forming a mechanical limiting constraint. This locking method requires no external power source and relies on a purely mechanical structure to achieve closure and fixation. For example, during instrument handling, even if subjected to external vibration, the engagement between the locking twist and the lock hole can maintain the closed state of the cover.

[0055] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the sample compartment cover 201 is hinged to the chassis assembly via an internal hinge 204 located in the second cavity. Specifically, the internal hinge 204 is positioned at the upper rear of the chassis assembly, working in conjunction with the telescopic support rod 205 to easily open and close the cover. Specifically, the upper rear of the main chassis 101 has a fixing point for the internal hinge 204, which can fix one side of the internal hinge 204, while the other side of the internal hinge 204 connects to the cover assembly 200. This internal hinge 204 effectively conceals the hinge structure, improving the overall integrity of the portable instrument. The internal hinge 204 refers to the rotating mechanism connecting the cover assembly 200 and the chassis assembly. Specifically, it can be implemented using a concealed hinge structure, with the hinge point located inside the second cavity, preventing the hinge from being exposed on the instrument's outer surface.

[0056] The cover assembly 200 further includes a telescopic support rod 205 engaged between the sample cover 201 and the chassis assembly, a handle 202 engaged with the sample cover 201, and a radiation baffle 206 engaged with the sample cover 201. The radiation baffle 206 is configured to block X-rays. The telescopic support rod 205 is a gas strut or a hydraulic strut. The radiation baffle 206 is a shielding structure located inside the sample cover 201, specifically made of lead plate or lead-containing composite material, covering the area corresponding to the X-ray emission path.

[0057] The sample chamber cover 201 is hinged to the main chassis 101 via an internal hinge 204. One end of the telescopic support rod 205 is hinged to the sample chamber cover 201, and the other end is hinged to the main chassis 101. Optimization of the hinge position allows for a large flip angle for the cover assembly 200, while requiring minimal force and causing minimal vibration when opening and closing. A radiation baffle 206 is fixed inside the sample chamber cover 201 in areas with high radiation intensity, effectively ensuring radiation safety. The handle 202 features a full-area arched design and is fixed to both sides of the sample chamber cover 201, providing a robust structure and a large lifting area for convenient operation. The sample chamber cover 201 has 90-degree rotatable locking buttons 203 on both sides. When the instrument needs to be lifted, the locking buttons 203 can be rotated to engage with the locking pins inside the main chassis 101, ensuring safety during lifting. A cover latch is fixed to the lower front of the sample chamber cover 201 and is used in conjunction with the cover opening button 104 to lock the cover assembly 200 during instrument testing.

[0058] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the chassis assembly includes a main chassis 101, a detachable rear cover 102 attached to the main chassis 101, and a cooling fan 103. An air outlet is provided on the upper part of the rear cover 102. An air inlet is provided on the lower part of the main chassis 101 on the side away from the rear cover 102. The cooling fan 103 is disposed in the first cavity and configured to draw air in through the air inlet and / or exhaust air through the air outlet. Preferably, the upper part of the main chassis 101 has a stepped groove for accurate installation and fixation of the detection component 300, and the sample stage 301 has mounting holes around its perimeter, which can be aligned with the holes in the stepped groove of the main chassis 101 and tightened with screws to ensure that the sample stage 301 is securely fixed. A detection system 302 is installed below the sample stage 301 to provide sample excitation and elemental detection.

[0059] The main chassis 101 is square in shape for easy carrying. The air inlet is located at the bottom front, and a cooling fan 103 is located at the upper left corner of the chassis rear cover 102. This forms a cooling airflow channel with air intake from the bottom and exhaust from the upper left rear, improving the heat dissipation environment of the testing system and ensuring a good heat dissipation and cooling channel during operation.

[0060] The bottom air intake of the main chassis 101 and the top air exhaust of the rear cover 102 form a vertical airflow path, and the cooling fan 103 is installed near the detection system 302. When the fan is turned on, outside air enters the first cavity through the bottom air intake, flows past the detection system 302 and heat-generating components such as the battery pack 400, and is then exhausted from the top air exhaust by the fan. This heat dissipation path utilizes the principle of natural upward movement of hot air, forming a bottom-to-top unidirectional circulating airflow through the superposition of active forced convection and passive thermal convection.

[0061] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the chassis assembly also includes feet attached to the bottom of the main chassis 101 and indicator lights 107 attached to the main chassis 101. The feet are adapted to create a gap between the bottom of the main chassis 101 and an external support. The indicator lights 107 are electrically connected to the interactive component to indicate the operating status. Preferably, the indicator lights 107 are LED strips. There are two indicator lights 107, respectively located on both sides of the cover opening button 104.

[0062] Four symmetrical columnar supports are installed at the four corners of the bottom of the main chassis 101, with a support height of 5 mm, to create a continuous airflow channel between the bottom of the chassis and the desktop. This channel forms a convection path with the cooling fan 103 on the rear cover 102 of the chassis. When the cooling fan 103 is working, external cool air can enter the air intake through the bottom gap, accelerating the internal heat exchange efficiency. The indicator light module 107 is embedded in the reserved holes on both sides of the front of the main chassis 101 and is connected to the control motherboard through a flexible circuit board. When the detection system 302 is started, the controller 601 drives the indicator light 107 to switch the display color according to the working stage. For example, it displays a solid blue light in standby mode, flashes green during detection, and flashes red quickly when there is a fault.

[0063] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 3 As shown, it also includes a communication component 500. The communication component 500 is electrically connected to the interaction component and the battery component 400 for communicating with the outside. The communication component 500 includes an external power interface, as well as a USB and / or HDMI and / or Ethernet port.

[0064] The communication component 500 is electrically connected to the controller 601 of the interaction component and the battery component 400 via internal cables. An external power interface allows an adapter to be connected to charge the battery component 400 and simultaneously power the detection system 302. A USB interface allows for direct export of test reports from a USB flash drive, an HDMI interface allows connection to an external display to expand the visualization interface, and a network port supports device access to a network server to upload test data. The communication component 500 is integrated into the rear cover 102 area of ​​the chassis; for example, interface slots are provided at the bottom of the rear cover 102, and the interfaces are arranged according to function and sealed with waterproof gaskets.

[0065] Through the above technical solutions, this application can improve the accuracy and stability of gold purity detection and reduce detection errors caused by the characteristics of the sample stage 301 material. Different material combinations can adapt to diverse testing scenarios such as laboratories and the field, achieving reliable detection signal transmission while ensuring radiation safety.

[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
