DETAILED DESCRIPTION
[0035] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] like Figure 1~Figure 5 As shown, this embodiment proposes
[0037] A chromaticity identification device for sodium ferric ethylenediaminetetraacetate products, comprising:
[0038] A main body 1 having a probe 2;
[0039] The protective cover 3 has a cavity 4 and is slidably arranged on the main body 1. The cavity 4 has an avoidance hole 5. After the protective cover 3 slides, the probe 2 slides into or out of the cavity 4 through the avoidance hole 5.
[0040] The baffle 6 is used to open or close the avoidance hole 5.
[0041] In this embodiment, in order to solve the problem that the colorimetric recognition device in the related art cannot protect the probe 2 well when in use, which leads to dust and other impurities in the air contaminating the probe 2 and causing errors in the detection results, this solution protects the probe 2 by designing a protective cover 3. In order to achieve the effect of protecting the probe 2 while ensuring the normal use of the probe 2 and ensuring the accuracy of the measurement, when the probe 2 is used for measurement, the baffle 6 opens the avoidance hole 5. During the process of relative sliding between the probe 2 and the protective cover 3, the probe 2 passes through the avoidance hole 5 and contacts the cuvette for measuring sodium ferric ethylenediaminetetraacetate. When not in use, the baffle 6 closes the avoidance hole 5 to prevent the probe 2 from being contaminated.
[0042] In order to prevent the protective cover 3 from being separated from the main body 1, the present solution can design several guide grooves on the main body 1 and several clamping protrusions on the protective cover 3. One clamping protrusion slides in one guide groove and will not be separated from the guide groove.
[0043] The principle of this scheme is to obtain the target chromaticity parameters of the sodium ferric ethylenediaminetetraacetate to be produced, input the target chromaticity parameters into the chromaticity regression model for calculation, and obtain the particle size parameters; input the particle size parameters into the particle size control regression model for calculation, and obtain the cumulative distribution parameters of the particle size; input the cumulative distribution parameters of the particle size into the production equipment of the sodium ferric ethylenediaminetetraacetate, so that the production equipment produces the sodium ferric ethylenediaminetetraacetate matching the target chromaticity parameters based on the cumulative distribution parameters of the particle size.
[0044] Furthermore, it also includes:
[0045] There are a plurality of first elastic members 7 , one end of which is arranged on the main body 1 , and the other end of which is arranged on the protective cover 3 . The first elastic member 7 is used to provide a force to keep the avoidance hole 5 away from the main body 1 .
[0046] In this embodiment, when the user uses the colorimetric identification device to measure the sodium iron ethylenediaminetetraacetate powder, the colorimetric identification device is first inverted on the support so that the probe 2 faces upward, the sodium iron ethylenediaminetetraacetate powder is placed in a cuvette, the cuvette containing the sodium iron ethylenediaminetetraacetate powder is placed on the protective cover 3, the protective cover 3 is pressed down, and the probe 2 is extended to contact the cuvette for detection. After the measurement is completed, in order to reset the probe 2, the present solution designs a plurality of first elastic members 7 between the protective cover 3 and the main body 1, and the function of the first elastic member 7 is to reset the protective cover 3. Placing the cuvette on the protective cover 3 and then pressing down the protective cover 3 may cause the cuvette to fall off. In order to prevent the cuvette from falling off, the protective cover 3 may be pressed down first, and then the cuvette may be placed.
[0047] Furthermore, it also includes:
[0048] There are a plurality of limit blocks 8 , which are arranged on the protective cover 3 and are located in the cavity 4 . After the protective cover 3 slides, the main body 1 abuts against the limit blocks 8 .
[0049] In the present embodiment, some users are accustomed to placing the cuvette on the protective cover 3 first, and then pressing down the protective cover 3. In order to prevent the protective cover 3 from being pressed down excessively and causing the cuvette to fall, the present solution is designed with a plurality of limit blocks 8. After the protective cover 3 slides, the main body 1 and the limit blocks 8 are in direct contact. There is a storage gap of the first elastic member 7 between the main body 1 and the protective cover 3. The protective cover 3 and the main body 1 cannot slide relative to each other. The probe 2 just extends out to a suitable position to contact the cuvette, and the probe 2 is in direct contact with the cuvette for detection.
[0050] Further, the protective cover 3 has a protective plate 9, the avoidance hole 5 is located on the protective plate 9, there are two baffles 6, and the two baffles 6 are both slidably arranged on the protective plate 9, and further includes:
[0051] There are several control members 10, and the several control members 10 are used to control the two baffles 6 to open or close the avoidance holes 5;
[0052] The control element 10 comprises:
[0053] The sliding rod 11 passes through the protective plate 9 and is slidably arranged on the limit block 8. After the protective cover 3 slides, the main body 1 abuts against the sliding rod 11, and the protective cover 3 and the sliding rod 11 slide relative to each other;
[0054] The connecting rod 12 has one end rotatably disposed on the sliding rod 11 and the other end rotatably disposed on the baffle 6. After the connecting rod 12 rotates, it is used to drive the baffle 6 to slide.
[0055] In this embodiment, in order to prevent the probe 2 from colliding with the baffle 6 when the protective cover 3 is pressed down, thereby causing damage to the probe 2, during the sliding process of the protective cover 3, due to the limiting effect of the protective plate 9 on the connecting rod 12, the sliding rod 11 slides with the protective cover 3. When the sliding rod 11 contacts the main body 1, the protective cover 3 continues to slide relative to the main body 1, and the sliding rod 11 slides along the limit block 8 and the protective plate 9. The limit block 8 and the protective plate 9 simultaneously limit the sliding rod 11 to ensure that the sliding rod 11 slides linearly. After the sliding rod 11 slides relative to the protective plate 9, it drives the connecting rod 12 to rotate. The length of the connecting rod 12 remains unchanged, so after the connecting rod 12 rotates, it drives the two baffles 6 to slide toward each other to open the avoidance hole 5.
[0056] Furthermore, the first elastic member 7 is sleeved on the sliding rod 11 .
[0057] In this embodiment, in order to prevent the first elastic member 7 from bending during compression, the first elastic member 7 is sleeved on the sliding rod 11 and the first elastic member 7 can only be extended and retracted along the direction of the sliding rod 11.
[0058] Furthermore, it also includes:
[0059] The second elastic member 13 has one end disposed on the protective cover 3 and the other end disposed on the baffle 6 . The second elastic member 13 is used to control the force of closing the avoidance hole 5 .
[0060] In this embodiment, since there is a period when the protective cover 3 and the main body 1 are sliding relative to each other, the sliding rod 11 and the main body 1 are not in contact with each other, so during the resetting process, after the first elastic member 7 is extended to the initial state, the sliding rod 11 and the main body 1 have been separated, and the sliding rod 11 cannot continue to slide, and the baffle 6 has not completely closed the avoidance hole 5, so the two second elastic members 13 are extended, so that the two baffles 6 can slide relative to each other until the avoidance hole 5 is completely closed, and the second elastic members 13 return to the initial state. During this process, the connecting rod 12 rotates relative to the baffle 6 and the sliding rod 11, and the sliding rod 11 continues to slide.
[0061] Furthermore, the main body 1 has an avoidance groove 14, and further includes:
[0062] The clamping block 15 is clamped on the protective cover 3 and slides into and out of the avoidance groove 14. The clamping block 15 is used to prevent the main body 1 and the protective cover 3 from sliding relative to each other.
[0063] In this embodiment, in order to prevent the probe 2 from extending out and causing the probe 2 to be contaminated when mispressed, a clamping block 15 is designed in this solution. The clamping block 15 is clamped on the protective cover 3 and slides on the protective cover 3. After sliding, it can slide into and out of the avoidance groove 14. When the clamping block 15 slides into the avoidance groove 14, the main body 1 and the protective cover 3 cannot slide relative to each other. When the clamping block 15 slides out of the avoidance groove 14, the main body 1 and the protective cover 3 can slide relative to each other. When measuring other objects, the protective cover 3 can be facing downward, and the main body 1 can be directly pressed down, so that the main body 1 and the protective cover 3 slide relative to each other, and the probe 2 can directly measure the object to be measured.
[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
