DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1-4 As shown, a constant temperature reaction box comprises a reaction box body 1, a fixing box 2, a temperature maintaining component 3 and a ventilation component 4, wherein the fixing box 2 is fixedly connected to one side of the reaction box body 1;

[0020] refer to Figure 1 , Figure 2 and Figure 3 As shown, a temperature maintenance component 3 is arranged inside the reaction box body 1, and the temperature maintenance component 3 includes a control component 31. The control component 31 is arranged on the front surface of the reaction box body 1. A storage component 32 is arranged inside the reaction box body 1. The storage component 32 includes a placement box 321 arranged inside the reaction box body 1. A through hole 322 is opened inside the placement box 321, and a temperature sensor 323 is arranged on one side of the inner wall of the placement box 321.

[0021] The control component 31 includes a box door 311 arranged on the front surface of the reaction box body 1 for sealing and protection, and a controller 312 is arranged on the front surface of the box door 311 .

[0022] The reaction box body 1 includes a first heating plate 5 arranged at the bottom of the inner cavity, a second heating plate 6 is arranged at the top of the inner cavity of the reaction box body 1, a through slot 7 is opened inside the reaction box body 1, and a fan 8 is arranged inside the fixing box 2.

[0023] The reaction box body 1 and the box door 311 are connected by hinges, and the reaction box body 1 and the box door 311 are convenient to maintain a closed state, which is beneficial to maintaining the temperature in the box. Under the action of the four placement boxes 321, it is convenient to classify and store the test samples. The inside of the reaction box body 1 is heated by the first heating plate 5 and the second heating plate 6, and the heat circulation is promoted through the through hole 322. With the cooperation of the controller 312 and the temperature sensor 323, it is convenient to control and monitor the temperature. When it is necessary to take and place samples, the control box door 311 is in an open state, and the placement box 321 needs to be pulled out for taking and placing operations, which can avoid other test samples from being exposed to the external environment and reduce the impact on other samples.

[0024] refer to Figure 1 and Figure 4 As shown, the ventilation component 4 is arranged inside the fixed box 2, and the ventilation component 4 includes a positioning member 41. The positioning member 41 is arranged on the inner side of the fixed box 2, and a connecting member 42 is arranged at the bottom of the positioning member 41. The connecting member 42 includes a first connecting frame 421 fixedly connected to the bottom of the first rack 413, and the bottom of the first connecting frame 421 is fixedly connected to the first baffle 422.

[0025] The positioning member 41 includes a support shaft 411 fixedly connected to one side of the inner wall of the fixing box 2 , one end of the support shaft 411 is rotatably connected to a gear 412 , and the outer side of the gear 412 is meshedly connected to a first rack 413 .

[0026] The inner side of the first connecting frame 421 is slidably connected to the supporting rod 9 , and the outer side of the supporting rod 9 is slidably connected to the second connecting frame 10 .

[0027] The second connecting frame 10 includes a fixing plate 11 fixedly connected to the top, a second rack 12 fixedly connected to one side of the fixing plate 11, a second baffle 13 fixedly connected to the bottom of the second connecting frame 10, and a stabilizing plate 14 slidably connected to the bottom of the second baffle 13.

[0028] The outer side of the second rack 12 is meshed with the gear 412, and one side of the stabilizing plate 14 is fixedly connected to one side of the inner wall of the fixed box 2. When the reaction box body 1 is not in use, it needs to be ventilated, and the first baffle plate 422 and the second baffle plate 13 are pushed in opposite directions respectively, so that the first baffle plate 422 and the second baffle plate 13 both slide on the inner side of the stabilizing plate 14. When the second baffle plate 13 is pushed, under the action of the second connecting frame 10 and the fixing plate 11, the second baffle plate 13 moves to drive the second rack 12 to move, and then drives the gear 412 to rotate under the support of the support shaft 411, so that the first rack 413 drives the first connecting frame 421 to slide under the limit of the support rod 9, and then drives the first baffle plate 422 to move. By controlling the first baffle plate 422 and the second baffle plate 13 to open synchronously, the fixed box 2 is in an open state, and the fan 8 is started. With the cooperation of the through groove 7, it is beneficial to promote the external and internal air circulation of the reaction box body 1.

[0029] Working principle: When in use, the first heating plate 5 and the second heating plate 6 facilitate heating the inside of the reaction box body 1. The controller 312 and the temperature sensor 323 cooperate to control and monitor the temperature inside the box, which is conducive to maintaining a constant temperature environment. The four placement boxes 321 facilitate classification and placement of samples. When sampling and testing samples are required, only the corresponding placement box 321 needs to be opened as needed to avoid other samples from being exposed to the external environment, reduce the impact on other samples, and help ensure the accuracy of the test data. When the reaction box body 1 is not in use, it is ventilated and the second baffle 13 is pushed. Under the action of the second connecting frame 10 and the fixed plate 11, the second baffle 13 moves to drive the second rack 12 to move, and then drives the gear 412 to rotate under the support of the support shaft 411, so that the first rack 413 drives the first connecting frame 421 to slide under the limit of the support rod 9, and then drives the first baffle 422 to move, so as to facilitate the synchronous control of the opening and closing of the first baffle 422 and the second baffle 13. Under the action of the through groove 7 and the fixed box 2, the reaction box body 1 is connected with the external environment, and the fan 8 is started to accelerate the air circulation and perform air exchange, which effectively avoids the reaction box body 1 being closed for a long time and causing an unpleasant odor inside.
