The present utility model provides a sample testing cartridge 100, referring to fig. 1 and 3, the sample testing cartridge 100 includes a base 101, a cover 102, a support 205, and a slide 208.

Referring to fig. 3 and 4, the base 101 has a light hole 103 and a receiving chamber 211 which are communicated with each other, and the light hole 103 is opened at a bottom wall of the receiving chamber 211. Slide 208 is positioned in receiving cavity 211, slide 208 can carry a sample (sample not specifically shown) to be tested, and the light aperture is oriented toward slide 208. Slide 208 is optically transparent (e.g., slide 208 may be made of quartz glass) so that light from raman spectrometer 500 can pass through slide 208 and strike the sample. The cover 102 is detachably connected with the base 101, and the cover 102 covers the side of the slide 208, which is opposite to the light hole 103.

Referring to fig. 5 and 3, the light hole 103 is provided for inserting the detecting device 501, and more specifically, referring to fig. 5, the detecting device 501 has a detecting probe 502, and the detecting probe 502 is inserted into the light hole 103. Light from inspection probe 502 can pass through slide 208 and impinge on a sample on slide 208, and scattered light from the sample can also pass through slide 208 and be received by inspection probe 502.

Referring to fig. 3, one method of operation of the sample testing cartridge 100 for loading samples is generally as follows: a sample may be placed on slide 208, then slide 208 is placed into receiving cavity 211 of housing 101, and cover 102 is then coupled to housing 101 such that cover 102 covers slide 208. Similarly, after the test is completed, the sample is removed by the following procedure: cover 102 is separated from base 101, slide 208 is removed, and the sample on slide 208 is poured out. After sample removal, slide 208 may be cleaned. The sample testing bin 100 is convenient to assemble and disassemble, convenient to load samples, and convenient to take out samples and clean the sample testing bin 100 after detection is completed.

According to the sample test bin 100 provided by the utility model, the slide 208 can be used for bearing samples, so that the samples are prevented from falling from the slide 208 to the light holes 103 to pollute the detection device 501; moreover, after the cover 102 is connected to the base 101, the cover 102 can cover the slide 208, which also prevents the sample from falling.

Other specific structures of the sample testing cartridge 100 are described below.

In one embodiment, the sample testing cartridge 100 further comprises a support 205, the support 205 is disposed in the accommodating cavity 211, the slide 208 is connected to an end of the support 205 near the light hole 103, the slide 208 and the support 205 together define a sample accommodating groove 301, and the cover 102 covers and closes the sample accommodating groove 301. The inside surface of the support 205 may block the sample from falling out of the sample receiving slot 301, further reducing the risk of the sample falling from the slide 208. In the case of the support 205, the slide 208 can be fixed to the support 205 and then, when the sample is to be loaded, the slide 208 can be placed directly in the housing 211 together with the support 205. It should be noted that in other embodiments, the support 205 is not necessary, and the slide 208 may be directly placed on the bottom wall of the accommodating chamber 211 without the support 205.

In an embodiment, the cover 102 and the base 101 may be connected by a threaded connection. For example, referring to fig. 2 to 4, the outer surface of the cover 102 has a first thread 203, and the sidewall of the receiving chamber 211 has a second thread 210, and the first thread 203 and the second thread 210 are screwed to each other. More specifically, the first screw 203 may be provided on the outer circumferential surface of the main body 202.

In some embodiments, in the case of a threaded connection between the cover 102 and the base 101, the distance between the slide 208 and the light-transmitting aperture 103 may vary with the movement of the cover 102. In this setting, the distance between the sample on the slide 208 and the laser light source of the raman spectrometer 500 can be changed by rotating the cover 102 and adjusting the position of the cover 102 relative to the base 101, so that the light of the detection device 501 is correctly focused on the sample, and the accuracy of detection is ensured.

For example, referring to fig. 2 to 4, in an embodiment, the sample testing cartridge 100 further includes an elastic element 209, the elastic element 209 is disposed in the accommodating cavity 211, one end of the elastic element 209 is connected to the bottom wall of the accommodating cavity, the other end of the elastic element 209 abuts against the supporting element 205, and one end of the supporting element 205 near the light hole 103 abuts against; the elastic member 209 and the cover 102 jointly clamp the support 205, so that the position stability of the support 205 and the tightness of the sample receiving groove 301 are ensured, wherein the elastic force of the elastic member 209 is used for driving the support 205 to move in a direction away from the light holes 103.

The elastic member 209 may be specifically configured as a spring, and the light emitted from the detecting device 501 may pass through the central space of the elastic member 209 and irradiate the slide 208. Referring to fig. 3, the elastic member 209 is in a compressed state, and if it is required to increase the distance between the slide 208 and the light-transmitting hole 103, the cover 102 can be rotated to move the cover 102 in a direction away from the light-transmitting hole 103. Accordingly, the compression degree of the elastic member 209 is reduced, the elastic member 209 is extended, and the support 205 is pushed to move, so that the slide 208 and the support 205 are moved away from the light hole 103. Similarly, referring to fig. 3, if it is desired to reduce the distance between slide 208 and light aperture 103, cover 102 can be rotated and cover 102 moved in a direction toward light aperture 103 and support 205 pushed so that slide 208 and support 205 move in a direction toward light aperture 103. Accordingly, the degree of compression of the elastic member 209 increases and the elastic member 209 contracts during this process. It should be noted that, during the process of rotating the cover 102, the support 205 may not rotate together with the cover 102.

In other embodiments, it is contemplated that the resilient member 209 may not be provided in the sample testing cartridge 100. For example, the supporting member 205 may be connected to the cover 102 by a snap-fit connection, and the supporting member 205 is suspended below the supporting member 205, so that when the cover 102 moves relative to the base 101, the supporting member 205 and the slide 208 connected to the supporting member 205 move together.

Referring to fig. 4, in one embodiment, support 205 has a channel 402 and a mounting slot 401, mounting slot 401 communicating with one end of channel 402, slide 208 mounted in mounting slot 401, slide 208 covering one end of channel 402 to form sample receiving slot 301. Specifically, the side surface of the slide 208 facing away from the light-transmitting hole 103 serves as the bottom wall of the sample-receiving groove 301, and the wall surface of the channel 402 serves as the side wall of the sample-receiving groove 301. The support 205 is provided with mounting slots 401 to facilitate positioning of the slide 208 when assembled with the support 205. The slide 208 and the wall of the mounting slot 401 can be adhesively connected.

More specifically, referring to fig. 4, in one embodiment, the support 205 includes a first cylinder 206 and a second cylinder 207, the first cylinder 206 having a smaller diameter than the second cylinder 207, the first cylinder 206 and the slide 208 being connected to both ends of the second cylinder 207, respectively; a part of the passage 402 is provided inside the first cylinder 206, another part of the passage 402 is provided inside the second cylinder 207, and the mounting groove 401 is provided inside the second cylinder 207. That is, the support 205 has a stepped cylindrical structure. Referring to fig. 2 to 4, the cover 102 is sleeved outside the first cylinder 206, and more specifically, the main body 202 of the cover 102 is sleeved outside the first cylinder 206; one end of the second cylinder 207, which is close to the first cylinder 206, abuts against the end face of the cover 102, i.e., the top end face of the second cylinder 207 abuts against the bottom end face of the cover 102. The cover body 102 is sleeved outside the first cylinder 206, so that radial positioning between the cover body 102 and the supporting piece 205 can be realized; the abutment of the second cylindrical body 207 with the end surface of the cover 102 can achieve axial positioning between the cover 102 and the support 205, and can improve the sealing effect on the sample-receiving groove 301.

Referring to fig. 2 to 4, in an embodiment, the cover 102 includes a main body 202 and a cover glass 204, the main body 202 is connected to the base 101, and the cover glass 204 is connected to the main body 202 and covers the sample receiving groove 301. Both the cover slip 204 and the slide 208 may be made of quartz glass. The cover slip 204 is provided mainly for improving the accuracy of detection. Specifically, for some samples (such as film-like samples), the light emitted by the detection device 501 may penetrate the sample and impinge on the cover 102, so that the spectrum collected by the detection device 501 may include the scattering spectrum of the material of the cover 102, which may affect the accuracy of the detection. Since raman scattering of glass is weak, the influence on the spectrum collected by detection is small, and thus, covering the sample receiving groove 301 with the cover glass 204 can reduce the influence of scattered light of the cover body 102 on the detection result, thereby improving the detection accuracy.

In addition, in order to improve the accuracy of detection, in an embodiment, the main body 202, the base 101, and the support 205 may be made of a light-impermeable material, so that the ambient light is prevented from being injected into the sample-receiving groove 301, thereby preventing the ambient light from interfering with the scattering spectrum of the sample. The light-impermeable material may be specifically light-impermeable plastic, metal, etc., and the materials of the main body 202, the seat 101, and the support 205 may be the same or different, so long as they can isolate ambient light, which is not specifically illustrated herein.

As mentioned above, the sample may be placed in the sample-receiving well 301 in a manner suitable for liquid-like or powder-like samples. For thin film type samples, it is conceivable to place in the sample-holding tank 301; alternatively, it is conceivable to have the support 205 and the cover glass 204 clamp the edges of the sample, thereby achieving loading of the film-like sample.

Specifically, referring to fig. 3, in an embodiment, an end face of the support 205 near an end of the cover slip 204 is covered by the cover slip 204, and a gap (the gap is not specifically labeled) is provided between the end face of the support 205 near the end of the cover slip 204 and the cover slip 204. Based on the specific orientation of fig. 3, there is a gap between the upper section of the support 205 and the lower surface of the cover slip 204. An edge portion of the film-like sample may be disposed in the gap, i.e., the edge of the film-like sample may be held by the cover glass 204 and the support 205. While the central area of the film-like sample is shielded above the sample receiving well 301, the light emitted by the detection device 501 can pass through the slide 208 and the sample receiving well 301 to impinge on the sample. The advantage of clamping the edges of the film-like sample using the cover glass 204 and the supporting member 205 is that the edge portion of the sample can be fixed in this way, preventing the material from moving greatly due to the shaking of the sample testing chamber 100, and preventing the material from wrinkling and curling, thereby improving the detection accuracy of the film-like sample.

In the case where it is necessary to sandwich the edge of the sample between the support 205 and the cover glass 204, the sample is loaded in the following manner, generally: after the cover glass 204 is connected to the main body 202, the main body 202 in fig. 4 is turned upside down, the sample is placed on the cover glass 204, then the support 205 is covered on the sample, and the base 101 is turned upside down outside the support 205.

Referring to fig. 4, in an embodiment, the end of the main body 202 near the light hole 103 has a socket groove 403, and the cover glass 204 may be disposed in the socket groove 403 and connected to a wall surface of the socket groove 403 (e.g., the cover glass 204 is fixed to the main body 202 by bonding), and the first cylinder 206 may be disposed in the socket groove.

The utility model also provides a raman spectrometer 500, wherein the raman spectrometer 500 comprises a detection device 501 and the sample testing cartridge 100 in any of the above embodiments. The detection device 501 includes a detection probe 502, and an end face of the detection probe 502 can emit light and collect scattered light. The detection probe 502 is detachably connected with the sample testing bin 100, the detection probe 502 is arranged in the light hole 103, and the end face of the detection probe 502 faces the slide 208.

According to the Raman spectrometer 500 disclosed by the utility model, the sample is not easy to fall from the slide 208, the sample test bin 100 is convenient to assemble and disassemble, the loading efficiency of the sample is high, and the detection efficiency of the Raman spectrometer 500 is high.

In one embodiment, raman spectrometer 500 is configured as a portable instrument. That is, the raman spectrometer 500 as a whole can be handled like a mobile phone by a user in his hand. The portable raman spectrometer 500 is convenient for a user to carry, who can carry the raman spectrometer 500 to different locations, meaning that the detection of the sample need not be limited to a particular laboratory.

The detection device 501 may have a display screen 503, in an embodiment, the display screen 503 may be configured as a touch screen, and a plurality of virtual keys that can be touched by a user may be displayed on the display screen 503, so that the user may operate the raman spectrometer 500 by touching the display screen 503. For example, after the user presses the "start" button on the display screen 503, the raman spectrometer 500 starts to automatically detect the sample, the detection probe 502 of the detection device 501 emits light and collects scattered light, and after waiting for a period of time, the test result may be shown on the display screen 503. Alternatively, in another embodiment, the display screen 503 is configured as a non-touch screen, and the detection device 501 is further configured with a physical button, so that the user can operate the raman spectrometer 500 by touching the physical button, so that the raman spectrometer 500 automatically detects the sample in the sample testing chamber 100.

In an embodiment, the base 101 includes a connection key 104, the connection key 104 is protruding on a wall surface of the light hole 103, the outer peripheral surface of the detection probe 502 has a connection groove 600, and the connection key 104 is clamped in the connection groove 600. The exterior of the connector 104 may abut the walls of the connector slot 600, thereby preventing the sample testing cartridge 100 from falling off the test probe 502. When it is desired to remove the sample testing cartridge 100, the user may pull the sample testing cartridge 100 out with a slight force to disengage the connector key 104 from the connector slot 600. The advantage of this arrangement is that the convenience of connection or disconnection between the sample testing cartridge 100 and the test probe 502 is high, and the use of tools such as screwdrivers and the like is not required, nor is the relatively cumbersome operation of screwing and the like required.

In an embodiment, the connection key 104 may be provided as a dot-shaped protrusion, and accordingly, the connection groove 600 may be provided as a dot-shaped protrusion. In another embodiment, the connecting slot 600 may be configured as shown in fig. 6 in order to further enhance the ease of assembly and disassembly between the sample testing cartridge 100 and the test probe 502. Referring to fig. 6, the connection groove 600 includes a first extension portion 601 and a second extension portion 602, the first extension portion 601 extends along an axial direction of the detection probe 502, the second extension portion 602 extends along a circumferential direction of the detection probe 502, an end surface of the detection probe 502 further includes an opening 603, two ends of the first extension portion 601 are respectively connected with one end of the opening 603 and one end of the second extension portion 602, the opening 603 is used for the connection key 104 to pass through, and the connection key 104 can slide in the first extension portion 601 and the second extension portion 602.

In the embodiment shown in fig. 6, the connection steps between the sample testing cartridge 100 and the test probe 502 are generally as follows: first, the connecting key 104 enters the first extending part 601 from the opening 603, and then the connecting key 104 slides along the first extending part 601; after the connecting key 104 slides to the connection position between the second extension portion 602 and the first extension portion 601, the connecting key 104 slides along the second extension portion 602, and finally the connecting key 104 is clamped at the end of the second extension portion 602 away from the first extension portion 601.

Similarly, the steps of separating the sample testing cartridge 100 from the test probe 502 are generally as follows: the connecting key 104 is slid along the second extension 602 to the connection between the first extension 601 and the second extension 602, and then the connecting key 104 is slid along the first extension 601 until the connecting key 104 leaves the first extension 601 from the opening 603.

For the embodiment shown in fig. 6, in the process of connecting or separating the sample testing cartridge 100 and the detection probe 502, the connection key 104 only needs to slide along the first extension portion 601 and the second extension portion 602, so that a user does not need to laboriously deform the light hole 103 radially to separate the connection key 104 from the connection groove 600, and therefore, the embodiment is beneficial to improving the convenience of disassembly and assembly between the sample testing cartridge 100 and the detection probe 502.

In one embodiment, the connection or disconnection between the sample testing cartridge 100 and the test probe 502 may be by some drive mechanism. For example, the outer peripheral surface of the sample testing cartridge 100 may be gripped by a motor-driven gripper, which is then rotated by an angle to move the motor-driven sample testing cartridge 100 along the second extension 602; next, a cylinder coupled to the motor may be activated, which drives the motor and clamp in a linear motion, thereby moving the sample testing cartridge 100 in its own axial direction and away from the test probe 502. In this way, automatic disassembly of the sample testing cartridge 100 may be achieved.
