Therefore, it should not be construed as a limitation of the present utility model. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Furthermore, in order to more clearly show the core technical solution of the present utility model, the description of the well-known structure of the analyzer is omitted below. However, this omission is only for the convenience of description and does not mean that the analyzer can be without these structures.

[0025] As Figures 1 - 3As shown in the figure, the present utility model proposes a dry powder particle analyzer, which includes: a frame 1, a detection component, a power supply module 4, an electrochromic glass 5, a power switch 7, and a control module 8. A door body 2 is provided on the frame 1, and an installation hole 3 is provided on the door body 2; the detection component is arranged inside the frame 1 and is used for detecting the sample to be measured; the power supply module 4 is arranged on the frame 1 and is used for providing electric energy; the electrochromic glass 5 is arranged in the installation hole 3, and the electrochromic glass 5 includes an electrochromic layer 6, and the electrochromic layer 6 is configured to change color after being electrically connected to the power supply module 4; before the electrochromic layer 6 changes color, its color is lighter and it is in a transparent state, and at this time light is allowed to pass through; after the electrochromic layer 6 changes color, its color is darker and it is in a semi-transparent or opaque state, and at this time its light-shielding effect is stronger; the color of some electrochromic glasses 5 is milky white or other light colors before color change, and is dark blue, brown, etc. after color change; in practical applications, appropriate electrochromic glasses can be selected according to specific requirements. The power switch 7 is arranged between the power supply module 4 and the electrochromic layer 6; the control module 8 is connected to the power switch 7, and the control module 8 is used for receiving external instructions and controlling the closing and opening of the power switch 7. The power switch 7 can be a relay switch.

[0026] In this embodiment, in order to solve the problem in the prior art that the light-shielding effect of the dry powder particle analyzer cannot be balanced with the convenience of observing the inside of the instrument, an electrochromic glass 5 is provided on the door body 2, and the electrochromic layer 6 is controlled to change color by the control module 8; during the detection process, the control module 8 controls the power switch 7 to close, and the power supply module 4 is electrically connected to the electrochromic layer 6 of the electrochromic glass 5, so that the electrochromic layer 6 changes color, thereby making the electrochromic glass 5 darker in color and becoming in a semi-transparent or opaque state, playing a role in blocking external light and reducing the influence of external light on the detection. When detection is not carried out, the control module 8 controls the power switch 7 to open, the electrical connection between the power supply module 4 and the electrochromic layer 6 is disconnected, and the electrochromic layer 6 returns to the light color before color change. At this time, light can pass through the electrochromic glass 5 and irradiate into the frame 1, facilitating the detection personnel to observe the internal situation of the instrument.

[0027] The control module 8 includes a signal receiving unit, and the signal receiving unit is connected to a computer or a remote control system and is used for receiving a start signal from the computer or the remote control system and controlling the closing and opening of the power switch 7 according to this signal. For example, when the detection personnel click the detection button on the computer, after the signal receiving unit receives the information to start the detection, it controls the power switch 7 to close.

[0028] Further, as Figure 2As shown in the figure, the electrochromic glass 5 further includes substrates 9 disposed on both sides of the electrochromic layer 6. A first conductive layer 10, an electrochromic layer 6, an electrolyte layer 11, an ion storage layer 12, and a second conductive layer 13 are sequentially disposed between the two substrates 9. The substrate 9 is made of glass or transparent plastic; both the first conductive layer 10 and the second conductive layer 13 are transparent conductive layers, having good electrical conductivity and light transmittance, capable of allowing light to pass through while conducting current, and generally the first conductive layer 10 and the second conductive layer 13 are respectively connected to the positive and negative electrodes of the module 4; the electrolyte layer 11 is used to conduct ions required for the color change reaction; the ion storage layer 12 is used to store or release ions to maintain the progress of the electrochromic reaction. When a voltage is applied to the first conductive layer 10 and the second conductive layer 13, the ions stored in the ion storage layer 12 will pass through the electrolyte layer 11 under the action of the electric field and combine with the color-changing material in the electrochromic layer 6, and the color-changing material undergoes an oxidation-reduction reaction, resulting in reversible changes in the color and transparency of the electrochromic layer 6.

[0029] Further, as Figure 4 shown, the detection component includes: a carrier plate 14 for placing the sample to be measured. The carrier plate 14 can be made of a light-transmitting material such as glass; a light source 15 disposed on the frame 1 for emitting light and passing it through the sample to be measured on the carrier plate 14. The light source 15 can be a parallel light source; a camera component 16 disposed on one side of the light source 15 for receiving the light passing through the sample to be measured and imaging it. The camera component 6 includes a lens and a camera. The reflected light enters the lens and the camera in sequence and then images the sample to be measured. The lens can be a telecentric auto-zoom lens, and the camera can be a high-resolution area array camera. As Figure 4 shown, the carrier plate 14 is placed horizontally and is located between the camera component 16 and the light source 15 in the vertical direction. When detecting, the light emitted by the light source 15 passes through the sample to be measured on the carrier plate 14 and then irradiates into the camera component 16 for imaging. The analyzer further includes a data processing unit, and the acquired image is transmitted to the data processing unit for analysis and calculation.

[0030] Further, as Figure 1 and Figure 4 shown, the detection component further includes: a reflecting mirror 17 disposed in front of the light source 15 along the propagation direction of the light in the light source 15. The reflecting surface of the reflecting mirror 17 forms a certain angle with the propagation direction of the light in the light source 15 and is not perpendicular. The light reflected by the reflecting mirror 17 passes through the carrier plate 14 and then enters the camera component 16 for imaging.

[0031] The optical path of the original analyzer is a straight optical path, and the light in the light source directly passes through the stage and enters the camera assembly, which will cause the analyzer to be too long in a certain direction and is not convenient for installation and use. In order to shorten the occupied space of the analyzer in a certain direction, a reflecting mirror 17 is provided in this embodiment. The reflecting mirror 17 is used to reflect the light emitted by the light source 15, changing the original straight optical path to a folded optical path. In this way, the light source 15 and the camera assembly 16 can be not on the same straight line, and as long as the stage 14 and the camera assembly 16 are arranged in the propagation direction of the reflected light in sequence. As Figure 4 shown, the light source 15 is horizontally arranged, and the emitted light propagates in the horizontal direction. After irradiating on the reflecting mirror 17, the reflected light propagates in the vertical direction until it enters the vertically arranged camera assembly 16 for imaging.

[0032] As Figure 4 shown, the reflecting surface of the reflecting mirror 17 forms a 45° angle with the propagation direction of the light in the light source 15, and the incident light and the reflected light are perpendicular to each other. In this way, the length of the optical path can be minimized as much as possible along the incident direction and the reflected direction. In addition, the reflecting surface can form an arbitrary angle with the propagation direction of the light in the light source 15, as long as the reflected light can enter the camera assembly 16 for imaging.

[0033] Furthermore, as Figure 4 shown, the detection assembly further includes: a moving support plate 18, on which a placement hole 35 for placing the stage 14 is provided. The placement hole 35 is used to allow light to pass through the moving support plate 18 and irradiate on the stage 14; a moving device 19, the moving support plate 18 is arranged on the moving device 19, and the moving device 19 is used to drive the moving support plate 18 to slide along the first direction and / or the second direction. The first direction is the length direction, represented by X in the figure, and the second direction is the width direction, represented by Y in the figure.

[0034] During detection, the stage 14 needs to be located between the camera assembly 16 and the reflecting mirror 17, and this position is not convenient for placement. And in order to capture a suitable field of view, the position of the stage 14 often needs to be adjusted. For this reason, the moving support plate 18 and the moving device 19 are provided. In the initial position, the moving support plate 18 is located on one side of the camera assembly 16 and the light source 15, which is convenient for placing the stage 14 in the placement hole 35. At this time, the position of the stage 14 is the lofting position; then the moving device 19 drives the moving support plate 18 to slide along the first direction and / or the second direction, and then drives the stage 14 to move between the camera assembly 16 and the light source 15 or the reflecting mirror 17. At this time, the position of the stage 14 is the position to be measured; during detection, after the light of the light source 15 irradiates on the reflecting mirror 17, the reflected light passes through the placement hole 35 and the stage 14 in sequence and then enters the camera assembly 16.

[0035] Furthermore, as Figure 5As shown in the figure, the mobile device 19 includes: a first lead screw 20 rotatably arranged on the frame 1 in a first direction, with a first slider 21 threadedly arranged on the first lead screw 20; a sliding plate 22 arranged on the first slider 21; a second lead screw 23 rotatably arranged on the sliding plate 22 in a second direction, with a second slider 24 threadedly arranged on the second lead screw 23, and a moving support plate 18 arranged on the second slider 24. The first lead screw 20 drives the moving support plate 18 to move in the first direction through the sliding plate 22, the second lead screw 23 drives the moving support plate 18 to move in the second direction, and when the first lead screw 20 and the second lead screw 23 act together, they can drive the moving support plate 18 to move in the horizontal plane.

[0036] Furthermore, as Figure 5 shown, the mobile device 19 further includes: a first slide rail 25 arranged in parallel with the first lead screw 20 on the frame 1, with a third slider 26 slidably arranged on the first slide rail 25, one end of the sliding plate 22 is arranged on the first slider 21, and the other end is arranged on the third slider 26; a second slide rail 27 arranged in parallel with the second lead screw 23 on the sliding plate 22, with a fourth slider 28 slidably arranged on the second slide rail 27, one end of the moving support plate 18 is arranged on the second slider 24, and the other end is arranged on the fourth slider 28. The first slide rail 25 and the third slider 26 make the movement of the moving support plate 18 in the first direction more stable; the second slide rail 27 and the fourth slider 28 make the movement of the moving support plate 18 in the second direction more stable.

[0037] The mobile device 19 further includes: a first driving device, the output end of the first driving device is connected to the first lead screw 20 for driving the first lead screw 20 to rotate; a second driving device, the output end of the second driving device is connected to the second lead screw 23 for driving the second lead screw 23 to rotate. The first driving device and the second driving device can be motors.

[0038] Furthermore, as Figure 1 shown, in order to further block external light, the frame 1 is provided with: a horizontal partition plate 29 and a vertical partition plate 31. The horizontal partition plate 29 is arranged above the moving support plate 18 in the horizontal direction, and a through hole 30 is arranged on the horizontal partition plate 29, and the through hole 30 is configured to enable the carrier plate 14 to pass through; the vertical partition plate 31 is arranged above the moving support plate 18 in the vertical direction; the vertical partition plate 31 and the horizontal partition plate 29 divide the space inside the frame 1 into a dispersion chamber 32 and a test chamber 33, and the detection component is arranged in the test chamber 33, and the dispersion chamber 32 communicates with the outside through the door body 2. After opening the door body 2, the dispersion chamber 32 communicates with the outside, and the carrier plate 14 can be placed or taken out through the through hole 30; after closing the door body 2, even if external light irradiates into the frame 1, due to the existence of the horizontal partition plate 29 and the vertical partition plate 31, the external light entering the test chamber 33 will be greatly reduced.

[0039] As Figure 1 shown, an indicator light 34 is further provided on the frame 1. The indicator light 34 can be connected to the control module 8. The indicator light 34 can be a breathing light, and its brightness and hue can be adjusted by the control module 8. For example, when the test is in progress, the control module 8 controls the indicator light 34 to turn green. When the test is completed, the control module 8 controls the indicator light 34 to turn blue. When a fault occurs in the instrument, the control module 8 controls the indicator light 34 to turn red. The current working state can be judged by the color of the light, and the test progress can be confirmed without the user observing repeatedly.
