Description

Technical Field

[0001] This utility model relates to the field of chemical detection technology, specifically to a drying oven for dehydrating test samples. Background Technology

[0002] Test strips are a type of paper that has been soaked in chemicals and can detect the presence of certain substances in liquids or gases through color changes. After some experiments are completed, it is necessary to keep the test strips for comparison with previous experiments. To facilitate preservation, the test samples often need to be dried.

[0003] Authorization notice CN220288050U discloses a mercuric bromide test paper drying device, including a drying chamber and a drying mechanism disposed within the drying chamber for drying mercuric bromide test papers. The opening of the drying chamber's inner cavity is located on one side wall. A side sealing plate is connected to the side of the opening of the drying chamber via multiple hinges. A servo motor is vertically mounted at the center of the bottom wall of the drying chamber. The output shaft of the servo motor passes through the drying chamber and is coaxially connected to an inner support shaft. Multiple positioning blocks are fixedly sleeved on the inner support shaft. Each positioning block is cylindrical, and a mounting plate is coaxially sleeved on the outer side of each positioning block. Multiple placement slots are formed on the top wall of each mounting plate. This mercuric bromide test paper drying device allows the reagent on the mercuric bromide test papers in multiple placement trays to evaporate almost simultaneously, thereby improving the efficiency of drying multiple mercuric bromide test papers at the same time and simplifying the drying process.

[0004] The test strips are placed in the tray, and three fans are powered on to create a good airflow in the drying chamber, allowing for rapid air circulation. However, the airflow cannot be controlled, which may cause unfixed test strips to be blown away, affecting the effectiveness of the test. Utility Model Content

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A drying oven for dehydrating test samples includes a box body, a door hinged to the side of the box body, the box body and the door forming a cavity when closed, and further includes:

[0008] The supporting structure includes a supporting frame, which is slidably disposed inside the box, and a supporting structure is also provided on the supporting frame;

[0009] The air supply structure is provided in two sets, which are respectively connected and symmetrically arranged at the upper and lower ends of the box door;

[0010] The air control structure comprises two sets, both located inside the housing. The two sets of air control structures are symmetrically arranged at the upper and lower ends of the support frame, and each set includes an upper baffle, a lower baffle, and a rotating structure. Several upper and lower baffles are provided, with the upper baffles linearly distributed along the width of the housing and rotatably connected to the housing.

The end of each worm gear is connected to a rotating shaft. The worm gear is rotatably connected to the housing through the rotating shaft. One of the worm gears is engaged with the turbine of the upper group, and the other worm gear is engaged with the turbine of the lower group.

[0012] As a further embodiment of this invention, the upper and lower sets of turbines are staggered.

[0013] As a further embodiment of this utility model: two grid plates are provided inside the box body, and the two grid plates are located on the upper and lower sides of the support frame.

[0014] As a further embodiment of this utility model: two limiting rods are symmetrically arranged on opposite sides of the box body, and sliding grooves are opened on both sides of the support frame, and the sliding grooves are slidably connected to the corresponding limiting rods.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-5 As shown, a drying oven for dehydrating test samples includes a box body 1 with several support legs 9 at the bottom. Heating wires are installed inside the box body 1 to improve drying efficiency. A door 2 is hinged to the side of the box body 1, and an observation window is provided on the door 2. The box body 1 and door 2, when closed, form a cavity 3. The drying oven also includes a support structure, an air supply structure, and an air control structure. The support structure includes a support frame 5, which is slidably disposed inside the box body 1. A support structure is also provided on the support frame 5. Two sets of air supply structures are provided, symmetrically arranged at the upper and lower ends of the door 2. Two sets of air control structures are provided, both disposed inside the box body 1. The two sets of air control structures are symmetrically arranged at the upper and lower ends of the support frame 5, and each includes an upper baffle 74 and a lower baffle 75. The rotating structure includes several upper baffles 74 and several lower baffles 75. The upper baffles 74 are linearly distributed along the width of the housing 1 and rotatably connected to it. Similarly, the lower baffles 75 are linearly distributed along the width of the housing 1 and rotatably connected to it. Two sets of rotating structures are provided. The upper baffles 74 and lower baffles 75 are controlled by corresponding rotating structures. These structures drive the corresponding upper baffles 74 or lower baffles 75 to rotate, thus changing their angles. By changing the angles of the upper and lower baffles 74 and 75, the ability to block airflow is altered. When both the upper and lower baffles 74 and 75 are horizontal, the blocking ability is maximized, effectively reducing airflow and preventing the test paper from being blown away, thus affecting the test results.

[0032] In some specific implementations, to facilitate changing the angle between the upper baffle 74 and the lower baffle 75, each set of rotating structures includes a turbine 73 and a worm gear 71. The rear side wall of the housing 1 has an installation cavity 7. Several turbines 73 are provided, and they are all rotatably connected inside the installation cavity 7. The turbines 73 are divided into upper and lower groups. There are two worm gears 71. The end of each worm gear 71 is connected to a rotating shaft 72. The worm gear 71 is rotatably connected to the housing 1 through the rotating shaft 72. One worm gear 71 is engaged with the turbine 73 of the upper group, and the other worm gear 71 is engaged with the turbine 73 of the lower group. The upper and lower sets of turbines 73 are staggered. In actual use, the rotating shaft 72 can be rotated to drive the worm gear 71 to rotate, and the turbine 73 engaged with it will drive the corresponding upper baffle 74 or lower baffle 75 to rotate, thereby changing the angle of the support leg 9.

[0033] In some specific implementation schemes, in order to further reduce the impact of wind, two grid plates 6 are installed inside the housing 1. The two grid plates 6 are located on the upper and lower sides of the support frame 5. The airflow is blocked by the grid plates 6, thereby reducing the airflow velocity.

[0034] In some specific implementations, to facilitate increasing the number of test strips that can be placed in the support frame 5, two limiting rods 4 are symmetrically arranged on opposite sides of the box body 1. Sliding grooves 53 are opened on both sides of the support frame 5, and the sliding grooves 53 are slidably connected to the corresponding limiting rods 4. An flared opening 54 is opened at the end of the sliding groove 53 away from the box door 2 for easy alignment. Several support rods 52 are arranged between the two side rods of the support frame 5, and several vertical rods 51 are arranged on the top of the support frame 5. The vertical rods 51 are arranged along the direction of the support rods 52, and a placement groove is formed between two adjacent vertical rods 51. The test strips to be dried are placed vertically in the placement groove. After the test strips are placed, the support frame 5 is pushed into the box body 1. By placing the test strips vertically between the vertical rods 51, the area occupied by a single test strip is reduced, thereby increasing the number of test strips that can be accommodated each time drying.

[0035] In some specific implementation schemes, in order to facilitate the sterilization of the air blown into the chamber 1, each air supply structure includes a filter box 8. One end of the filter box 8 is connected to an air inlet duct 85, and the other end is connected to a fan 83. A sterilization plate 84 is also provided at the connection between the fan 83 and the filter box 8. The sterilization plate 84 is used to perform preliminary sterilization of the air. A sterilization structure is also provided inside the filter box 8. The inner sidewall of the filter box 8 is staggered with guide plates 81 to form an air duct inside the filter box 8. The sterilization structure includes several sterilization lamps 82, which are arranged between corresponding two guide plates 81. The air entering the filter box 8 moves along the guide plates 81. By setting the sterilization lamps 82 in the air duct inside the filter box 8 to use ultraviolet sterilization, the air entering the air duct is sterilized with ultraviolet light before air is supplied, so as to avoid bacteria in the air coming into contact with the test paper and causing contamination, thereby affecting the test results.

[0036] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
