DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-8 , a DNA sample drying device includes a drying box 1, the drying box 1 is provided with a drying chamber 11, and the four corners of the inner wall of the drying chamber 11 are provided with limiting mechanisms 6, and a sample test tube placement rack mechanism 4 is placed on the limiting mechanism 6, and a plurality of DNA sample test tubes 5 are evenly arranged and placed on the sample test tube placement rack mechanism 4. The sample test tube placement rack mechanism 4 includes a bottom plate 42, and a placement plate 41 is horizontally provided above the bottom plate 42. A fixing rod 43 is fixedly connected between the bottom plate 42 and the placement plate 41, and a plurality of circular holes 411 are evenly arranged and opened on the placement plate 41. The DNA sample test tube 5 is inserted and placed at the circular holes 411, and a plurality of limiting holes 421 are evenly arranged on the upper surface of the bottom plate 42. The bottom of the DNA sample test tube 5 is against the limiting holes 421, and the placement plate 41 can separate the multiple DNA sample test tubes 5 to ensure that hot air can circulate between the DNA sample test tubes 5.

[0027] Among them, handles 44 are symmetrically provided on both sides of the upper surface of the placement plate 41, and the handles 44 are convenient for the operator to lift the sample tube placement rack mechanism 4 as a whole.

[0028] In addition, the limiting mechanism 6 includes a limiting block 62, and the four corners of the bottom plate 42 are against the limiting block 62. A connecting block 61 is fixedly connected to one side of the limiting block 62, and the connecting block 61 is fixedly connected to the inner wall of the drying chamber 11. The limiting block 62 can effectively prevent the position of the bottom plate 42 from changing.

[0029] Moreover, ventilation holes 13 are symmetrically opened on the side walls of both sides of the drying box 1, and dustproof nets 14 are set at the ventilation holes 13. A fan 3 is installed on the outer wall of the drying box 1 outside the ventilation holes 13, and the fan 3 can make the air inside the drying chamber 11 flow.

[0030] Among them, a plurality of mounting holes 15 are evenly opened on the outer wall of the drying box 1 outside the ventilation opening 13, and mounting plates 31 are symmetrically fixedly connected to the side walls on both sides of the fan 3. The mounting plates 31 are installed at the mounting holes 15. The mounting holes 15 facilitate the fixed installation of the mounting plates 31 on the fan 3.

[0031] Moreover, heating tubes 12 are symmetrically arranged on the inner wall of the drying chamber 11 below the limiting mechanism 6, and an upper cover 2 is horizontally arranged on the upper surface of the drying box 1. The heating tubes 12 can convert the air inside the drying chamber 11 into hot air, thereby accelerating the drying speed.

[0032] In this embodiment, when the operator needs to dry multiple DNA sample test tubes 5, the upper cover 2 can be removed from the drying box 1, and then the operator pulls the handle 44 to lift the sample test tube placement rack mechanism 4 out of the drying chamber 11, and then places the DNA sample test tubes 5 that need to be dried on the placement plate 41, passes the DNA sample test tubes 5 through the circular holes 411, and then makes the bottoms of the DNA sample test tubes 5 rest against the limiting holes 421. After all the DNA sample test tubes 5 are placed, the sample test tube placement rack mechanism 4 can be put back into the drying chamber 11.

[0033] Ensure that the four corners of the bottom plate 42 are installed at the limit blocks 62, and then the upper cover 2 can be placed on the drying box 1, and then the fans 3 on both sides can be turned on to allow the air inside the drying chamber 11 to circulate, and the fans 3 exhaust or blow air into the drying chamber 11 through the vents 13. The dustproof net 14 can effectively prevent dust from entering the drying chamber 11, and the heating tube 12 can generate a certain temperature, so that hot air exists in the drying chamber 11, and after the fan 3 makes the air flow, the hot air flows between the DNA sample test tubes 5, uses the hot air as a medium, and contacts the DNA sample test tubes 5, thereby drying the DNA samples in the DNA sample test tubes 5.

[0034] In the present invention, by providing a sample tube placement rack mechanism 4, multiple DNA sample tubes 5 can be effectively placed, and the multiple DNA sample tubes 5 can be separated, thereby ensuring that hot air can flow better between these DNA sample tubes, thereby improving the drying efficiency, making the DNA samples in the DNA sample tubes 5 dry faster, and shortening the time required for the overall DNA sample detection.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
