Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical experimental technology, specifically a safety laboratory fume hood. Background Technology
[0002] In chemical experiments and scientific research, fume hoods are widely used as crucial experimental equipment to handle and analyze processes that may generate harmful gases. These harmful gases often need to be effectively exhausted through the fume hood's exhaust system during experiments to ensure a clean experimental environment and the safety of operators. However, during the exhaust process, a frequently overlooked problem gradually emerges: when gases containing harmful components are discharged through the exhaust duct, condensation easily forms at the exhaust outlet due to temperature drops, pressure changes, or interactions between gas components.
[0003] Traditional fume hood designs often focus solely on the effective exhaust of gases, neglecting the treatment of condensate. This condensate, which may contain various harmful substances generated during the experiment, poses several risks if left untreated and drips indiscriminately. First, condensate may drip directly onto the experimental subjects, contaminating the samples and consequently affecting the accuracy and reliability of the experimental data.
[0004] To address the problems raised in the background art, those skilled in the art have proposed a safe laboratory fume hood. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a safe laboratory fume hood, which uses an inclined ventilation filter plate and is equipped with a special guide channel to guide condensate into a storage tank, ensuring that the condensate can be quickly and effectively guided to a designated collection area after it is generated.
[0006] A safety laboratory fume hood, wherein a storage box is installed on the inner side of the bottom of the main body of the experimental rack, and a placement groove is provided on the inner side wall of the main body of the experimental rack;
[0007] A guiding mechanism is provided between the main body of the experimental rack and the placement slot. The guiding mechanism includes an inclined baffle, which is fixedly connected to the inner side of the top of the placement slot near the top of the main body of the experimental rack. Two inclined guide plates are fixedly connected to the two sides of the top of the placement slot near the inclined baffle. A water flow channel is provided on the inner side wall of the main body of the experimental rack, and multiple guide slots are provided at the bottom of the inclined baffle.
[0008] The storage component is located on the inner side wall of the main body of the experimental rack near the placement slot.
[0009] Preferably, the storage component includes a storage box, which is slidably connected to the inner side wall of the experimental rack body near the placement slot. The inner side wall of the storage box has a storage slot, and the outer side wall of the storage box is fixedly connected to a connecting handle.
[0010] Preferably, the guide groove is a long groove formed at the bottom of the inclined baffle to guide water droplets into the water flow channel, and the inclined baffle is installed in an inverted V shape on the inner side wall of the experimental frame body to separate the water droplets on both sides.
[0011] Preferably, the storage tank is also provided on both sides of the top of the storage box for connecting to the water tank to collect the water leaking from the water tank.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. During use, water vapor will be generated in the placement tank. The water vapor will gather at the position of the inclined baffle, and then the water vapor will be guided by the guide groove at the bottom of the inclined baffle, so that the water vapor enters the water tank through the guide groove and the inclined guide plate, thus preventing water vapor from dripping.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0020] As attached Figure 1 To be continued Figure 4 As shown:
[0021] Example 1: According to Figure 1-4As shown, this utility model provides a safe laboratory fume hood, with a storage box 11 installed on the inner side of the bottom of the experimental rack body 1, and a placement groove 12 opened on the inner side wall of the experimental rack body 1.
[0022] A guiding mechanism is set between the experimental rack body 1 and the placement slot 12. The guiding mechanism includes an inclined baffle 2, which is fixedly connected to the inner side of the top of the placement slot 12 near the top of the experimental rack body 1. Two inclined guide plates 21 are fixedly connected to the two sides of the top of the placement slot 12 near the inclined baffle 2. A water channel 22 is opened on the inner side wall of the experimental rack body 1, and multiple guide slots 23 are opened at the bottom of the inclined baffle 2.
[0023] The storage component is located on the inner side wall of the main body 1 of the experimental rack near the placement slot 12. During use, water vapor will be generated in the placement slot 12. The water vapor will gather at the position of the inclined baffle 2, and then the water vapor will be guided by the guide slot 23 at the bottom of the inclined baffle 2. The water vapor will be guided by the guide slot 23 and the inclined guide plate 21 to enter the water tank 22, thus preventing water vapor from dripping.
[0024] The storage unit includes a storage box 24, which is slidably connected to the inner side wall of the experimental rack body 1 near the placement slot 12. The inner side wall of the storage box 24 is provided with a storage slot 25, and the outer side wall of the storage box 24 is fixedly connected with a connecting handle 26. Through the setting of the storage slot 25, the condensate guided by the water trough 22 can be collected and collected into the storage slot 25. The storage slot 25 is also provided on both sides of the top of the storage box 24 for connecting with the water trough 22 to collect the water leaking from the water trough 22.
[0025] The guide groove 23 is a long groove at the bottom of the inclined baffle 2, used to guide water droplets into the water flow groove 22. The inclined baffle 2 is an inverted V-shaped installation on the inner side wall of the experimental frame body 1, used to separate the water droplets on both sides. The guide groove 23 is a long groove and its shape matches that of the inclined baffle 2, which can more conveniently guide the condensate.
[0026] Working principle: When this device is needed, water vapor will be generated in the placement tank 12 during the experiment. The water vapor condenses at the bottom of the inclined baffle 2. Through the shape of the inclined baffle 2 and the guidance of the guide groove 23, the condensed water can enter the water flow tank 22. The inclined guide plate 21 can prevent the dripping condensed water from falling into the placement tank 12. The condensed water is guided by the water flow tank 22 into the storage box 24 for storage.
