Description

Technical Field

[0001] This utility model relates to the field of portable spectrometers, and in particular to a wheel-type portable mobile phone spectrometer. Background Technology

[0002] In recent years, portable spectrometers based on smartphones have significantly improved the portability and ease of use of devices by integrating miniature optical systems with mobile terminals. Existing portable mobile phone spectrometers miniaturize and retain the core components of the spectrometer, integrating them into a palm-sized box. They are fixed behind the phone camera by the outer shell and use the CMOS sensor in the camera and the phone flash, along with a built-in app, to realize the spectrometer's spectral testing function.

[0003] The relative positions of the flash and camera differ between various mobile phone models, meaning that existing portable mobile phone spectrometers are only compatible with a specific model. Using the same portable mobile phone spectrometer on other models is impossible, increasing the complexity of structural design for different models. Users who want to analyze water spectral signals using a mobile phone spectrometer must own the corresponding mobile phone model, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a wheel-type portable mobile phone spectrometer, which solves the technical problem that existing portable mobile phone spectrometers cannot be used with various mobile phone models.

[0005] A wheel-type portable mobile phone spectrometer includes a spectrometer module and a clamping mechanism for holding the mobile phone.

[0006] The spectrometer module is connected to the clamping mechanism via an adjustable wheel mechanism. The wheel mechanism is used to adjust the alignment of the spectrometer module's spectral output with the mobile phone camera. The spectrometer module's spectral input is connected to the light source end of a plug-in light source via an optical fiber. The power supply end of the plug-in light source is connected to the mobile phone's charging interface.

[0007] Optionally, the wheel mechanism includes a wheel plate and a limiting bolt;

[0008] The wheel plate has an oblong through hole, the limiting bolt passes through the oblong through hole and is threadedly connected to the clamping mechanism, and the spectrometer module is mounted on the wheel plate at the end away from the oblong through hole.

[0009] Optionally, the plug-in light source includes a plug-in bulb and a lampshade;

[0010] The light-emitting end of the plug-in bulb is connected to one end of the lampshade, and one end of the optical fiber is connected to the other end of the lampshade. The power input interface of the plug-in bulb is compatible with the mobile phone charging interface. During spectral detection, the power input interface of the plug-in bulb is connected to the mobile phone charging interface.

[0011] Optionally, the power supply interface of the plug-in bulb is a Type-C interface, a Lightning interface, or a Micro-USB interface.

[0012] Optionally, the clamping mechanism includes a first L-shaped clamping plate and a second L-shaped clamping plate for clamping the two side walls of the mobile phone;

[0013] The bottom plates of the first L-clamp and the second L-clamp are slidably sleeved together, and a return spring is provided between the bottom plates of the first L-clamp and the second L-clamp.

[0014] Optionally, the spectrometer module includes a spectrometer housing, an inner spectrometer housing embedded in the spectrometer housing, and an upper cover plate fastened to the spectrometer housing.

[0015] The outer shell and inner shell of the spectrometer are provided with a light source inlet and a spectral outlet. The light source inlet is connected to the other end of the optical fiber. An optical path is formed between the light source inlet and the spectral outlet of the inner shell of the spectrometer using optical elements.

[0016] Optionally, the outer wall of the spectral outlet of the spectrometer housing is provided with an external thread, and the end of the wheel plate away from the waist-shaped through hole is provided with a threaded through hole, and the external thread is threadedly connected to the threaded through hole.

[0017] Optionally, a detection slot is provided on the inner housing of the spectrometer, and the detection slot is located in the optical path of the inner housing of the spectrometer;

[0018] The spectrometer housing has placement holes on its outer side wall that correspond to the position of the detection slot. During spectral detection, the sample container passes through the placement holes and is embedded in the detection slot.

[0019] Optionally, both the outer casing and the inner casing of the spectrometer are L-shaped, with the light source inlet and the spectral outlet located at opposite ends of the L-shaped casing.

[0020] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0021] 1. During spectral detection, the clamping mechanism is clamped onto the mobile phone. By adjusting the length and angle of the wheel mechanism, the spectral output of the spectrometer module is aligned with the mobile phone camera, making the portable mobile phone spectrometer suitable for any model of mobile phone and with a wide range of applications.

[0022] 2. This application uses a plug-in light source, with the plug-in bulb connected to the mobile phone charging interface as the light source. Compared with traditional mobile phone spectrometers that use the mobile phone flash as the light source, this application maintains a passive design while increasing the brightness of the light source and improving the accuracy of spectral detection.

[0023] 3. When installing the portable mobile phone spectrometer of this application, a stable clamping mechanism is first used to achieve the installation. Then, the position of the spectrometer module is adjusted by adjusting the length and angle of the wheel plate and tightening the limit bolt. This application achieves the rapid installation of the portable mobile phone spectrometer through "one clamp, one turn and one rotation", which is simple to operate.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] Example:

[0039] like Figure 1 The portable mobile phone spectrometer shown includes a spectrometer module 1 and a clamping mechanism 2 for holding the mobile phone.

[0040] The spectrometer module 1 and the clamping mechanism 2 are connected by an adjustable wheel mechanism 3. The wheel mechanism 3 is used to adjust the spectral output of the spectrometer module 1 to align with the mobile phone camera. The spectral input of the spectrometer module 1 is connected to the light source end of the plug-in light source 5 through an optical fiber 4. The power supply end of the plug-in light source 5 is connected to the charging interface of the mobile phone.

[0041] In this embodiment, when using the portable mobile phone spectrometer, the clamping mechanism 2 is opened and clamped to the back of the mobile phone, and the spectrometer module 1 is installed on one end of the wheel mechanism 3. The length and angle of the wheel mechanism 3 are adjusted so that the spectral output of the spectrometer module 1 is aligned with the mobile phone camera. The sample to be tested is placed on the spectrometer module 1, and the power supply end of the plug-in light source 5 is connected to the charging interface of the mobile phone. The light emitted by the plug-in light source 5 is converted into a spectral signal after passing through the optical fiber 4 and the spectrometer module 1 and is captured by the camera. After analysis by the smart app, the detection of the sample to be tested is completed.

[0042] like Figure 1 and Figure 5 As shown, the wheel mechanism 3 includes a wheel plate 301 and a limiting bolt 302;

[0043] The wheel plate 301 has an oblong through hole 303. The limiting bolt 302 passes through the oblong through hole 303 and is threadedly connected to the clamping mechanism 2. The spectrometer module 1 is installed on the wheel plate 301 at the end away from the oblong through hole 303.

[0044] In this embodiment, in order to reduce the distance between the spectral output of the spectrometer module 1 and the mobile phone camera, the wheel plate 301 is set as a Z-shaped plate, and a handwheel is provided at one end of the limiting bolt 302. When adjusting the position, first loosen the limiting bolt 302, and then adjust the angle and length of the wheel plate 301. When the spectral output of the spectrometer module 1 is directly opposite the mobile phone camera, tighten the limiting bolt 302 to limit the angle and length of the wheel plate 301, thereby realizing the position adjustment of the spectrometer module 1 so that it can meet the needs of any mobile phone model.

[0045] like Figure 1 As shown, the plug-in light source 5 includes a plug-in bulb 501 and a lampshade 502;

[0047] In this embodiment, the power input interface of the plug-in bulb 501 is a Type-C interface, a Lightning interface, or a Micro-USB interface. During spectral detection, the light emitted by the plug-in bulb 501 passes through the lamp cover 502 and the optical fiber 4 to the spectrometer module 1. Compared with traditional mobile phone spectrometers that use the mobile phone flash as a light source, this application maintains a passive design while increasing the brightness of the light source, thereby improving the accuracy of spectral detection.

[0048] like Figure 1 , Figure 6 and Figure 7 As shown, the clamping mechanism 2 includes a first L-shaped clamping plate 201 and a second L-shaped clamping plate 202 for clamping the two side walls of the mobile phone;

[0049] The bottom plates of the first L-clamp 201 and the second L-clamp 202 are slidably sleeved together, and a return spring 203 is provided between the bottom plates of the first L-clamp 201 and the second L-clamp 202.

[0050] In this embodiment, a sliding groove is provided on the bottom plate of the first L-clamp 201, and the bottom plate of the second L-clamp 202 is slidably engaged in the sliding groove on the bottom plate of the first L-clamp 201. A long strip-shaped limiting groove is provided at the bottom of the bottom plate of the second L-clamp 202, and a return spring 203 is placed in the limiting groove. One end of the return spring 203 abuts against the top plate on the sliding groove of the first L-clamp 201. By providing the return spring 203, the clamping mechanism 2 can stably clamp the mobile phone during clamping.

[0051] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the spectrometer module 1 includes a spectrometer outer shell 101, a spectrometer inner shell 102 embedded in the spectrometer outer shell 101, and an upper cover plate 103 fastened to the spectrometer outer shell 101.

[0052] The spectrometer outer shell 101 and the spectrometer inner shell 102 are provided with a light source inlet 104 and a spectral outlet 105. The light source inlet 104 is connected to the other end of the optical fiber 4. The light source inlet 104 and the spectral outlet 105 of the spectrometer inner shell 102 are connected by optical elements to form an optical path.

[0053] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the spectral outlet 105 of the spectrometer housing 101 is provided with an external thread, and the end of the wheel plate 301 away from the waist-shaped through hole 303 is provided with a threaded through hole 304, and the external thread is threadedly connected to the threaded through hole 304.

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a detection slot 106 is provided on the inner housing 102 of the spectrometer, and the detection slot 106 is located in the optical path of the inner housing 102 of the spectrometer.

[0055] The outer shell of the spectrometer housing 101 has a placement hole 107 on its side wall that corresponds to the position of the detection groove 106. During spectral detection, the sample container passes through the placement hole 107 and is embedded in the detection groove 106.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the outer casing 101 and the inner casing 102 of the spectrometer are L-shaped casings, and the light source inlet 104 and the spectral outlet 105 are located at the two ends of the L-shaped casings, respectively.

[0057] In this embodiment, the inner housing 102 of the spectrometer is provided with a meandering channel connecting the light source inlet 104 and the spectral outlet 105. Optical element slots are formed at predetermined positions on the channel wall of the meandering channel. Its optical path includes a transmission hole, a detection slot 106, a slit, a grating, and a lens, etc. In this embodiment, the optical path is existing technology and will not be described in detail here. During spectral detection, the sample to be tested is first placed in a sample container, and then the sample container is embedded in the detection slot 106 for spectral detection. In this embodiment, the sample container is a transparent cuvette, gas cell, or other sample box.

[0058] like Figure 8, Figure 9 and Figure 10 The figures shown are the spectral results of purified water, cola, and grape juice measured using the wheel-type portable mobile phone spectrometer described in this application. Figure 8 , Figure 9 and Figure 10 The accuracy of the detection in this application is high.

[0059] In summary, during spectral detection, the clamping mechanism 2 is clamped onto the mobile phone. By adjusting the length and angle of the wheel mechanism 3, the spectral output of the spectrometer module 1 is aligned with the mobile phone camera, making this portable mobile phone spectrometer suitable for any model of mobile phone, thus having a wide range of applications. Furthermore, by setting a plug-in light source 5 and a plug-in bulb 501 connected to the mobile phone charging interface as the light source, compared to traditional mobile phone spectrometers that use the mobile phone flash as the light source, this application maintains a passive design while increasing the brightness of the light source, thereby improving the accuracy of spectral detection.
