Description

Technical Field

[0001] This utility model relates to the field of portable spectrometers, and in particular to a clip-on 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 different mobile phone models, which means that existing portable mobile phone spectrometers are only compatible with a specific model. It is impossible to use the same portable mobile phone spectrometer on other models, which increases the amount of structural design required for different models. At the same time, existing portable mobile phone spectrometers have problems such as inconvenient adjustment or poor stability in actual use. Utility Model Content

[0004] The purpose of this invention is to provide a clip-on portable mobile phone spectrometer. This addresses the technical problems of existing portable mobile phone spectrometers being incompatible with various mobile phone models and suffering from inconvenient adjustment and poor stability.

[0005] A clip-on portable mobile phone spectrometer includes a spectrometer module, a clamping mechanism for holding the mobile phone, and a slider mechanism that is slidably disposed in the clamping mechanism.

[0006] The spectral outlet of the spectrometer module is mounted on a slider mechanism, which is used to adjust the alignment of the spectral outlet of the spectrometer module with the mobile phone camera. The light source inlet of the spectrometer module is connected to the light source end of the plug-in light source through an optical fiber, and the power supply end of the plug-in light source is connected to the charging interface of the mobile phone.

[0007] Optionally, the clamping mechanism includes a left clamping plate and a right clamping plate arranged symmetrically;

[0008] A U-shaped bracket is installed at the bottom end of the left clamping plate, and two shouldered pressure rods are installed at the bottom end of the right clamping plate. Sliding holes are opened on the two columns of the U-shaped bracket, and the two shouldered pressure rods are slidably disposed in the two sliding holes respectively. A return spring is sleeved on the shouldered pressure rod, and a ring platform for limiting the return spring is provided at the front end of the sliding hole.

[0009] Optionally, the slider mechanism includes a sliding plate;

[0010] The skateboard has grooves on both sides, and the inner sides of the two columns of the U-shaped bracket are provided with slide bars. The grooves on both sides of the skateboard are slidably engaged with the slide bars on both sides.

[0011] Optionally, a sleeve is provided on the skateboard;

[0012] A spectral through hole is provided on the slide plate below the sleeve, and the axial direction of the sleeve is perpendicular to the sliding direction of the slide plate.

[0013] Optionally, the plug-in light source includes a plug-in bulb and a lampshade;

[0014] The light source 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 plug-in bulb is connected to the mobile phone charging interface.

[0015] Optionally, the power supply interface of the plug-in bulb is a Type-C interface, a Lightning interface, or a Micro-USB interface.

[0016] 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.

[0018] 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;

[0019] 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.

[0020] 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.

[0021] Due to the adoption of the above technical solution, this utility model has the following advantages:

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 attached clip-on portable mobile phone spectrometer shown includes a spectrometer module 1, a clamping mechanism 2 for clamping the mobile phone, and a slider mechanism 3 slidably disposed in the clamping mechanism 2.

[0040] The spectral outlet of the spectrometer module 1 is mounted on the slider mechanism 3. The slider mechanism 3 is used to adjust the spectral outlet of the spectrometer module 1 to align with the mobile phone camera. The light source inlet of the spectrometer module 1 is connected to the light source end of the plug-in light source 5 through the 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 placed on the side walls of the mobile phone on both sides of the mobile phone camera. The spectrometer module 1 is then installed onto the slider mechanism 3. The position of the slider mechanism 3 is 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 terminal of the plug-in light source 5 is connected to the charging port 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 , Figure 5 and Figure 6 As shown, the clamping mechanism 2 includes a left clamping plate 201 and a right clamping plate 202 arranged symmetrically.

[0043] A U-shaped bracket 203 is installed at the bottom end of the left clamping plate 201, and two shouldered pressure rods 204 are installed at the bottom end of the right clamping plate 202. Sliding holes 205 are opened on the two columns of the U-shaped bracket 203. The two shouldered pressure rods 204 are slidably disposed in the two sliding holes 205 respectively. A return spring 206 is sleeved on the shouldered pressure rod 204. A ring platform for limiting the return spring 206 is provided at the front end of the sliding hole 205.

[0044] In this embodiment, both the left clamping plate 201 and the right clamping plate 202 are stepped clamping plates, which can perfectly avoid the volume and power buttons of the mobile phone to achieve stable clamping.

[0045] like Figure 1 , Figure 5 and Figure 6 As shown, the slider mechanism 3 includes a slide plate 301;

[0046] The slide plate 301 has sliding grooves on both sides, and the inner sides of the two columns of the U-shaped bracket 203 are provided with sliding strips. The sliding grooves on both sides of the slide plate 301 are slidably engaged with the sliding strips on both sides.

[0048] A spectral through hole 303 is provided on the slide plate 301 below the sleeve 302, and the axial direction of the sleeve 302 is perpendicular to the sliding direction of the slide plate 301.

[0049] In this embodiment, by adjusting the position of the clamping mechanism 2, the spectral through-hole 303 and the mobile phone camera are positioned in the same vertical plane after clamping by the clamping mechanism 2. In this embodiment, the sleeve 302 is a rectangular sleeve, and the sleeve 302 has the same structure and size as one end of the spectral outlet 105 of the spectrometer housing 101, which facilitates the placement of the spectrometer module 1. During spectral detection, one end of the spectral outlet 105 of the spectrometer housing 101 is inserted into the sleeve 302, and the spectral through-hole 303 is adjusted to align with the mobile phone camera. The spectral signal passes through the spectral through-hole 303 and is captured by the mobile phone camera.

[0050] like Figure 1 As shown, the plug-in light source 5 includes a plug-in bulb 501 and a lampshade 502;

[0051] The light source end of the plug-in bulb 501 is connected to one end of the lamp cover 502, and one end of the optical fiber 4 is connected to the other end of the lamp cover 502. The power input interface of the plug-in bulb 501 is compatible with the mobile phone charging interface. During spectral detection, the plug-in bulb 501 is connected to the mobile phone charging interface.

[0052] 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.

The light source inlet 104 is connected to the other end of the optical fiber 4. The spectral outlet 105 of the spectrometer housing 101 is embedded in the sleeve 302. The light source inlet 104 and the spectral outlet 105 of the spectrometer inner housing 102 form an optical path using optical elements.

[0056] 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.

[0058] In this embodiment, the inner housing 102 of the spectrometer is provided with a detour 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 detour 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.

[0059] like Figure 7 , Figure 8 and Figure 9 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 7 , Figure 8 and Figure 9 The accuracy of the detection in this application is high.

[0060] In summary, during spectral detection, the clamping mechanism 2 is clamped to the side walls of the mobile phone on both sides of the camera. The position of the slider mechanism 3 is adjusted to align the spectral output of the spectrometer module 1 with the mobile phone camera, making this portable mobile phone spectrometer suitable for any model of mobile phone, with a wide range of applications and simple and quick position adjustment. At the same time, this application uses a plug-in light source 5 and a plug-in bulb 501 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.
