Description

Technical Field

[0001] The utility model relates to the technical field of drying boxes, in particular to a drying box used in an environment monitoring laboratory. Background Art

[0002] In the environmental monitoring laboratory, the collected samples are tested and analyzed using instruments to determine whether the pollutant content exceeds the standard. After the instrument is used, it is necessary to use a drying oven to dry the instrument to prevent the sample from corroding the instrument and prevent the instrument from rusting. A drying oven is a device used to dehydrate or heat treat instruments or samples. It is a commonly used instrument and equipment, mainly used to dry samples, and can also provide the temperature environment required for the experiment.

[0003] After searching, the Chinese patent with patent announcement number CN211782408U discloses a drying box for environmental monitoring laboratories, including a drying box cabinet, a heating port, an upper cabinet and a lower cabinet. The inner walls of the left and right sides of the drying box cabinet are both provided with a first sliding track, and the internal pulleys of the first sliding track are both connected to a drying bracket, and the interior of the drying bracket is installed with a limit block. A drying box for environmental monitoring laboratories is provided with a dirt collection drawer, so that the dirt collection drawer can be slid to a suitable position through a second sliding track, which is convenient for cleaning garbage and impurities inside the device. During the operation and processing of the device, certain water stains and impurities will be generated, so that the generated impurities and water stains can be prevented from being easily retained inside the device, thereby solving the problem of easy formation of dirt and bacteria inside the device over a long period of time, improving the drying efficiency of the device, improving the detection efficiency of the device, and increasing the detection accuracy of the required detection items.

[0004] However, the above design still has some shortcomings. In the above design, the position of the electric heater is relatively fixed. During the drying process, the dried objects that are closer to the electric heater are prone to over-drying, while the dried objects that are farther away from the electric heater are prone to incomplete drying, which will reduce the detection accuracy of the detected objects.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0022] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

A connected air inlet channel 5 is opened at the top of the drying chamber 17, and a first dustproof net 14 is fixedly set at the upper end of the inner part of the air inlet channel 5, and a heating wire 6 is set at the bottom of the first dustproof net 14. A mounting plate 15 is fixedly set at the bottom of the heating wire 6, and a fan 8 is installed at the bottom of the mounting plate 15. A through hole 7 is opened through the surface of the mounting plate 15, and the number of the through holes 7 is two;

[0025] Specifically, Figure 1 and Figure 2 As shown, when in use, the electric heating wire 6 can be used to heat the air, and the wind force generated by the rotation of the fan 8 can be used to blow the heat into the drying chamber 17, so as to dry the dried items in the placement slot 13. At the same time, the output end of the motor 4 can be used to drive the rotating rod 11 to rotate slowly, and the rotation of the rotating rod 11 drives the U-shaped rod 10 to rotate. The rotation of the U-shaped rod 10 drives the placement slot 13 to rotate through the installation sleeve 12, and the rotation of the placement slot 13 drives the dried items to rotate. Through the rotation of the dried items, the dried items can be evenly dried, thereby improving the accuracy of the detection of the detected items, and solving the problem that the position of the electric heater is relatively fixed, and the dried items closer to the electric heater are prone to over-drying during the drying process, while the dried items farther away from the electric heater are prone to incomplete drying, which will reduce the detection accuracy of the detected items.

[0026] Wherein: by disposing the first dustproof net 14 and the second dustproof net 16, it is possible to prevent external dust from entering the drying chamber 17 during the drying process.

[0027] A limiting mechanism 9 is arranged inside the placement slot 13, and the limiting mechanism 9 includes a rotating plate 905, and the rotating plate 905 is rotatably arranged outside the placement slot 13, a transmission rod 904 is fixedly connected to the other side of the rotating plate 905, and one end of the transmission rod 904 extends to the inside of the placement slot 13, a bidirectional screw 902 is fixedly connected to the other side of the transmission rod 904, and a moving block 906 is threadedly connected to the outer wall of the bidirectional screw 902, and a lower end surface of the moving block 906 is penetrated by a movably arranged limiting rod 903, and the top of the moving block 906 is fixedly connected to the limiting plate 901;

[0028] Specifically, Figure 2 and Figure 3 As shown, when in use, after the dry objects are placed in the placement groove 13, the rotating plate 905 can be rotated, and the rotating plate 905 rotates through the transmission rod 904 to drive the bidirectional screw 902 to rotate, and the rotation of the bidirectional screw 902 drives the two moving blocks 906 to move in a direction approaching each other, and the movement of the two moving blocks 906 drives the two limiting plates 901 to move in a direction approaching each other until they contact the dry objects in the placement groove 13 and effectively fix them. By fixing the dry objects in the placement groove 13, the safety of the dry objects during rotation can be improved.

[0029] Working principle: In the present application, the electric heating wire 6 can be used to heat the air, and the wind force generated by the rotation of the fan 8 can blow the heat into the drying chamber 17, so as to dry the dry items in the placement slot 13. At the same time, the output end of the motor 4 can be used to drive the rotating rod 11 to rotate slowly, and the rotation of the rotating rod 11 drives the U-shaped rod 10 to rotate. The rotation of the U-shaped rod 10 drives the placement slot 13 to rotate through the installation sleeve 12, and the rotation of the placement slot 13 drives the dry items to rotate. Through the rotation of the dry items, the dry items can be evenly dried, thereby improving the detection of the detected items. Secondly, when the dry objects are placed in the placement groove 13, the rotating plate 905 can be rotated, and the rotating plate 905 rotates through the transmission rod 904 to drive the bidirectional screw 902 to rotate, and the bidirectional screw 902 rotates to drive the two moving blocks 906 to move in the direction of approaching each other, and the two moving blocks 906 move to drive the two limiting plates 901 to move in the direction of approaching each other until they contact the dry objects in the placement groove 13 and effectively fix them. By fixing the dry objects in the placement groove 13, the safety of the dry objects during rotation can be improved.
