Description

Technical Field

[0001] The utility model relates to a clarity measuring instrument, in particular to a mouthwash clarity measuring instrument. Background Art

[0002] The clarity detection of mouthwash is one of the links in the quality detection of mouthwash. The clarity measuring instrument emits a diffuse reflection light source to irradiate the mouthwash solution in a transparent container. If there are fine particles in the solution, when the linear light passes through the solution, it can cause the phenomena of light scattering and light absorption. Then, through the comparison of different backgrounds of the white projection area or the black projection area, it is possible to obtain whether there are foreign matters in the solution to be detected through the human eye. Therefore, the judgment of the clarity of mouthwash highly depends on the operator's eyes to check the situation. Therefore, a magnifying glass structure is usually used for assistance. However, the magnifying glass structure of the existing clarity measuring instrument realizes mobile adjustment, either by being installed on a sliding structure fixedly arranged on the chassis in a non-detachable manner, or by being assembled to the side wall of the chassis with clamping jaws. Among them, the non-detachable setting method makes the adjustment or disassembly of the magnifying glass inflexible. The clamping jaw method can meet the flexibility but lacks reliability. Especially, the clamping jaw spring structure is prone to failure, which will affect the normal use of the magnifying glass structure. Content of the Utility Model

Detailed Description of the Invention

[0022] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.

[0023] The utility model discloses a clarifying degree measuring instrument for mouthwash, and the overall structure is arranged as Figure 1 shown, which includes a main chassis 1. The main chassis 1 is located on a bottom plate 2, and a measuring space 12 for clarifying degree measurement is separated by the main chassis 1 and the bottom plate 2 together.

[0024] Based on the diffuse reflection light emission illumination principle of the traditional clarifying degree measuring instrument, a diffuse reflection type LED light source 11 is distributed at the top of the measuring space 12. The diffuse reflection type LED light source 11 is installed and arranged relying on the main chassis 1 and has a high-power LED electronic chip. A digital circuit board for adjusting the illumination intensity is correspondingly arranged in the main chassis 1. The side walls of the measuring space 12 and the upper surface of the bottom plate 2 are both laid with white or black PVC reflective plates 5. The PVC reflective plates are of photographic grade to better reflect the foreign matters in the solution.

[0025] Preferably, in order to reduce the external scattering of the light source, as Figure 1 shown, a light shielding plate 4 structure can be arranged at the lintel position of the main chassis 1.

[0026] When the mouthwash solution in the transparent container is placed in the measuring space 12 for clarifying degree measurement, in order to improve the reliability of visual inspection, a magnifying glass is usually used for auxiliary inspection. Since the operator needs to hold the transparent container containing the mouthwash, the magnifying glass needs to be installed on the main chassis 1 for use.

[0027] For the clarifying degree measuring instrument for mouthwash disclosed by the present invention, considering the inconvenience of using the traditional magnifying glass installation structure, a new magnifying glass installation structure is designed, specifically:

[0028] First, as Figure 1 shown, first, a fixed support 7 is welded to a side wall structure of the main chassis 1. As Figure 2 shown, the fixed support 7 is of a lug type structure and has a through hole 72 penetrating up and down. Secondly, as Figure 1 shown, an adjusting assembly 6 is rotatably installed on the support column 7. The structure of the adjusting assembly 6 is arranged as Figure 3 shown, which includes a main body rod 61 and a threaded rod 63. The main body rod 61 is welded to the threaded rod 63, and a retaining ring 62 is fixed at the connection position of the main body rod 61 and the threaded rod 63. Correspondingly, a limiting ring groove 71 for the retaining ring 62 to be inserted into is formed around the top end of the through hole 72 of the support 7.

[0029] Thus, after the threaded rod 63 passes downward through the through hole 72 of the support 7, the retaining ring 62 is inserted into the limiting ring groove 71, which prevents the entire adjustment assembly from being separated from the support 7 on the one hand, and plays a certain role in limiting and preventing shaking on the other hand. After the threaded rod 63 passes downward through the through hole 72 of the support 7, the screw nut 8 is locked and connected by the thread structure, so tightening the screw nut 8 can lock the adjustment assembly 6 in the current state, and loosening the screw nut 8 can rotate and adjust the adjustment assembly 6.

[0030] For example Figure 2 As shown, the adjustment component 6 also needs to meet the installation requirements of the magnifying glass 10. An interface 64 for connecting the flexible bending tube 9 is provided on one side of the main rod 61. One end of the flexible bending tube 9 is fixedly connected to the interface 64; the flexible bending tube 9 is assembled with the magnifying glass 10 at the other end through a threaded interface and a threaded joint structure.

[0031] The flexible bending tube 9 is made of carbon steel and has good bending and shaping performance. The flexible bending tube 9 is set to a sufficient length so that the magnifying glass 10 can be flexibly adjusted to a use position. In addition, the magnifying glass 10 is connected to the flexible bending tube 9 with a detachable thread structure, and can be replaced when the magnifying glass 10 is worn.

[0032] In addition, a wear-resistant pad 3 is fixedly laid under the bottom plate 2 to improve the protective effect of the bottom plate 2 when it is placed on the test table.

[0033] It can be seen that for the mouthwash clarity measuring instrument disclosed by the utility model, the installation structure of the magnifying glass is improved. First, the magnifying glass is set with a flexible bending tube of sufficient length, and the viewing and using position of the magnifying glass can be flexibly adjusted, and the adjustment operation is simple and convenient. Secondly, the support is supported and set with an adjustment component, a screw nut and a support structure. The support is welded and fixed to the main box. The adjustment component and the screw nut are locked with a threaded structure, which is not easy to loosen, so it has good reliability. In addition, the adjustment component and the screw nut are also detachable, so that the structure of the magnifying glass can be replaced, the structure of the magnifying glass can be maintained, and the influence of external interference factors on the measurement results can be reduced; furthermore, the support is used as a rotation support point, so that the entire magnifying glass structure can also be rotated and adjusted, further improving the flexibility of adjustment and use. At the same time, when the magnifying glass is not needed, the magnifying glass can also be rotated to a position not located at the front side of the measurement space, thereby solving the inconvenient operation problem that the traditional magnifying glass cannot be removed or needs to be removed and stored.

[0034] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
