Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, and in particular relates to a clarity inspection lamp detector. Background Technology

[0002] Clarity refers to the clarity of a solution being equivalent to that of the solvent used, or not exceeding that of a turbidity standard solution of 0.5. Clarity testing is used to examine trace amounts of insoluble impurities in a drug, and a turbidity standard solution is used as the standard for clarity testing.

[0003] Chinese patent document CN113740280A discloses a clarity inspection umbrella lamp, including a front box and a back plate fixed to the rear of the front box. The front of the front box is provided with a projection observation window, and a sample turbidimetric tube holder mechanism is provided in front of the projection observation window. A switch and a touch screen are provided on the front box below the projection observation window. The switch and touch screen are respectively connected to a power supply, a microcontroller, and a PWM board located inside the front box via power lines. The power supply is connected to a power interface on the side wall of the front box. A light source projection box is provided inside the front box. The light source projection box has a semi-enclosed structure with an opening at the front. LED light sources are respectively provided on the upper and lower sides of the front of the light source projection box. A reflector is provided behind the LED light sources. The inner surface of the light source projection box is covered with black velvet. The LED light sources are connected to the microcontroller and the PWM board via leads.

[0004] In the above technical solution, due to the structural and positional issues of the LED light source in the light source projection box, the light is affected during actual testing, thus affecting the testing accuracy.

[0005] Therefore, it is necessary to develop a new clarity inspection light detector to improve detection accuracy by increasing the light brightness of the clarity inspection light. Summary of the Invention

[0006] The purpose of this invention is to provide a clarity inspection lamp inspection instrument that improves detection accuracy by increasing the light brightness of the clarity inspection.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is that the clarity inspection lamp detector is used to inspect the clarity of the sample to be tested, including an outer casing, a sample placement position, and a projection light source component; the projection light source component is disposed in the outer casing, and the projection light source of the projection light source component is tilted towards the sample placement position; the projection light source component includes a projection light outlet, and the projection light emitted by the projection light source component is projected onto the sample placement position through the projection light outlet.

[0008] The projection light source component is housed within the outer casing, preventing excessive light scattering. Notably, unlike existing technologies, the projection light source of the projection light source component is tilted towards the sample placement area, resulting in more light being projected onto the sample placement area, providing more concentrated and sufficient light for clarity checks.

[0009] Preferably, the projection light source component includes a first projection light source and a second projection light source respectively arranged vertically upwards and downwards; both the first projection light source and the second projection light source are tilted towards the sample placement position to be tested.

[0010] By employing two projection light sources, a first projection light source and a second projection light source, the two projection beams are superimposed at the sample placement position, resulting in a doubling of the projection light intensity, better clarity inspection effect, and a better user experience.

[0011] Preferably, the angle at which the first and second projection light sources are tilted toward the sample placement position is 20-60°, and the light source lines projected by the first and second projection light sources form an overlapping area at the sample placement position.

[0012] With the above-described structure, the light source lines projected by the first projection light source and the light source lines projected by the second projection light source form an overlapping area at the sample placement position. The sample placement position is located in the overlapping area of ​​the two light projections, resulting in better light intensity for clarity inspection.

[0013] Preferably, the angle at which the first projection light source and the second projection light source are tilted toward the sample placement position is 45°, and the light source line projected by the first projection light source and the light source line projected by the second projection light source intersect at the sample placement position at an angle of 90°.

[0014] With the above-described structure, the light source line projected by the first projection light source and the light source line projected by the second projection light source intersect at a 90° angle at the sample placement position. The sample placement position is located at the intersection of the two light projections, and the point projection makes the light intensity for clarity inspection better.

[0015] Preferably, the projection light source component includes a projection housing, and both the first projection light source and the second projection light source are located inside the projection housing; the projection housing is provided with heat dissipation holes.

[0016] The heat dissipation holes are used to diffuse the heat generated by the first and second projection light sources.

[0017] Preferably, the sample placement position is provided with a sample holder, and the front end of the sample holder is provided with an observation window; a touch screen and several switches are provided below the observation window, and the several switches are used to adjust the light projected by the projection light source component.

[0018] The sample holder is used to hold test tubes containing samples to be tested; the observation window is used to observe the inspection status of the samples in the test tubes; and the touch screen is used to display the clarity inspection data.

[0019] Preferably, a fan is also provided inside the outer casing; a power socket located on the back of the outer casing is connected to a circuit board, and the fan is also electrically connected to the circuit board; the touch screen and the switch are both connected to the circuit board.

[0020] Preferably, the outer casing is provided with a removable rear cover; a drawer assembly is provided above the projection light source component, the drawer assembly being used to store the illuminance instrument.

[0021] Preferably, the projection light outlet is located adjacent to the sample holder to be tested.

[0022] Preferably, the touch screen is equipped with a touch module with 24 preset colors; by adopting the touch screen design with 24 preset colors, the color system close to the sample color can be directly selected, and the background light color can be adjusted to be close to the sample color with one click.
