DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0021] Please refer to Figure 1 and Figure 2 The embodiment provides an acid and alkali resistant reagent cabinet, and the reagent cabinet is also called a sample holding cabinet, is one of the most commonly used experimental equipment in a laboratory, and is a cabinet for storing chemical reagents. The reagent cabinet generally comprises a cabinet body 1 and a cabinet door 2, wherein the cabinet body 1 is provided with a top plate 11 and a bottom plate 12, side plates 13 located on both sides and a back plate 14 located at the back, the cabinet door 2 is located at the front, and a plurality of horizontal plates 8 for supporting are arranged in the cabinet body 1 from top to bottom.
[0022] When the chemical reagents stored in the reagent cabinet leak due to a bottle plug not being tightly plugged or other situations, harmful or irritating gases are easily generated by volatilization, and the chemical gases coming from the front can cause discomfort to the workers when the workers open the cabinet door 2 each time.
[0023] Please refer to Figure 1 and Figure 2 To solve the above technical problems, the two side plates 13 are provided with air suction pipes 3, the two air suction pipes 3 are jointly connected with a suction mechanism 4, a fan is provided with an air exhaust pipe 5 away from one side of the air suction pipe 3, the air exhaust pipe 5 is provided with an activated carbon filter screen 6, and the outlet of the air exhaust pipe 5 is opposite to the direction of the cabinet door 2.
[0024] In the initial state, the cabinet door 2 is in the closed state, and the entire reagent cabinet is in the closed state. When a chemical reagent bottle needs to be taken, in order to reduce the influence of harmful gases in the reagent cabinet on the workers due to leakage, the suction mechanism 4 is first operated to work, the suction mechanism 4 sucks and processes the air in the reagent cabinet through the air suction pipe 3, so that after the cabinet door 2 is opened, the air suction pipe 3 continuously sucks the air, the air at the cabinet door 2 is only sucked from the outside to the inside, is transported to the air exhaust pipe 5 through the suction mechanism 4, the gas in the reagent cabinet is reduced to flow out to the outside, and the health of the workers is affected. At the same time, under the transportation of the air exhaust pipe 5, the air in the reagent cabinet passes through the activated carbon filter screen 6. If the chemical reagents in the reagent cabinet leak, the activated carbon filter screen 6 can filter the acid and alkali components in the reagent cabinet to a certain extent, so that the danger of the discharged air is reduced.
[0025] Please refer to Figure 1 and Figure 2 The suction mechanism 4 comprises a suction fan 41 and a controller 42, a button 43 is arranged on the cabinet door 2, the suction fan 41 and the button 43 are electrically connected with the controller 42, and the air suction pipe 3 is connected with the suction fan 41.
[0026] Before opening the cabinet door 2, the experimenter presses the button 43 in advance, and the button 43 transmits an electrical signal to the controller 42, which controls the start of the air suction fan 41. The air suction fan 41 processes the air in the reagent cabinet through the air suction pipe 3.
[0027] To improve the air suction effect of the air suction pipe 3 and further reduce the air leakage outside the reagent cabinet through the cabinet door 2.
[0028] Please refer to Figure 2 and Figure 3 , the air suction pipe 3 includes a first pipe 31 and a plurality of second pipes 32, the pipe is connected with each second pipe 32, the first pipe 31 is connected with the air suction mechanism 4, the inner diameter of the first pipe 31 is larger than that of the second pipe 32, the horizontal plate 8 divides the side plate 13 into multiple layers, and the second pipe 32 is fixedly installed on each layer of the side plate 13. The second pipe 32 is provided with a plurality of small holes 33 on the side away from the connected side plate 13.
[0029] After the air suction mechanism 4 works, the entire air suction pipe 3 is in a negative pressure state, at which time the second pipe 32 sucks air outside, wherein the power of the air suction mechanism 4 is large, so that the single small hole 33 on the single second pipe 32 cannot balance the pressure in the first pipe 31, so that the small holes 33 on the multiple second pipes 32 collectively suck air in the reagent cabinet to balance the pressure in the first pipe 31, so that the small holes 33 on the second pipes 32 on each layer of the side wall can generate suction force, thereby absorbing the air in each layer of the reagent cabinet and reducing the air leakage in the reagent cabinet.
[0030] If the cabinet door 2 is opened too fast and the amplitude is too large, the air suction mechanism 4 cannot quickly suck the air in the reagent cabinet, so the opening process of the cabinet door 2 needs to be relatively slow, but an unknowing person may understand that it is opened relatively quickly.
[0031] Please refer to Figure 1 , Figure 4 and Figure 5 , to solve the above technical problems. The cabinet door 2 and the cabinet body 1 are connected through the adapter 7, the adapter 7 includes a rotating drum 71 fixedly installed on the cabinet door 2, the rotating drum 71 is provided with a shaft 72 rotatingly arranged in the rotating drum 71, the both ends of the shaft 72 are fixedly connected with the cabinet body 1, and the shaft 72 is fixedly installed with a friction block 73 in contact with the inner wall of the rotating drum 71.
[0032] The cabinet door 2 is opened by rotating, wherein in order to delay the opening speed of the cabinet door 2, the friction block 73 is arranged on the shaft 72, so that the cabinet door 2 is opened, the friction block 73 is in contact with the inner wall of the rotating drum 71, so that the force required for opening the cabinet door 2 is increased, the opening time of the cabinet door 2 is prolonged, and the larger opening force is different from the general cabinet door 2, so as to remind the experimental personnel to pay attention to the abnormality in the reagent cabinet.
[0033] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
