[0002] In various laboratories, the lab table is the primary platform for conducting experimental operations. However, during the experimental process, large amounts of harmful and odorous gases and dust are often generated. For example, in chemistry experiments, chemical reactions may release toxic chemical fumes such as chlorine and sulfur dioxide; in biology experiments, specimen handling may produce biohazardous aerosols; and in materials experiments, operations such as grinding and cutting generate large amounts of fine dust.

[0003] If these harmful gases and dusts are not promptly handled, they can pose a serious threat to the health of laboratory personnel, leading to respiratory illnesses, allergic reactions, and even more serious poisoning. They can also affect the accuracy of experimental results, as certain gases or dusts may react with experimental samples or reagents, causing deviations in experimental data.

[0004] Currently, laboratories typically use fume hoods or integrated ventilation systems to address gas and dust issues. While fume hoods can effectively treat hazardous substances within the work area, they are limited in space, covering only a specific operating range, and are costly and require significant space. Integrated ventilation systems often suffer from high energy consumption and lack the ability to effectively address hazardous substances generated by a specific lab table, making them ineffective in ensuring air quality around individual lab tables.

[0005] Therefore, there is a need for a self-purification device that can be directly applied to a laboratory table to effectively treat harmful, odorous gases and dust generated during the use of the laboratory table, so as to ensure the safety of the experimental environment and the reliability of the experimental results.

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in 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.

[0029] The following references Figures 1-7 The utility model is described as follows:

[0030] Embodiment: a self-purification type desktop air suction device, including baffle 1, baffle 1 is long strip, baffle 1 is long strip, this shape makes it can be conveniently placed on the desktop, and a certain shielding effect is played. The design of long strip can also adapt to the length of different desktops, and provide a more extensive application range.

[0031] Baffle 1 is internally hollow, and baffle 1 is internally hollow. This hollow structure is the key of the whole air suction device. It provides a channel for the flow of air, so that air can be transmitted inside the baffle.

[0032] The front side of baffle 1 is provided with an air inlet 2 communicating with the inside thereof, the air inlet 2 is arranged at the middle position of baffle 1, the air inlet 2 is arranged on the front side of baffle 1 and located at the middle position. The air inlet arranged at the middle position helps to uniformly suck the harmful gas or dust generated in the desktop area. When harmful substances are generated, whether they are on the left side or the right side of the desktop, the air inlet at the middle position can more evenly capture these pollutants.

[0033] An air inlet net cover 4 is arranged at the air inlet 2. The air inlet net cover 4 is arranged at the air inlet 2. The air inlet net cover has multiple functions. First, it can prevent larger foreign objects from entering the inside of the baffle, avoiding blocking the internal air channels. Second, it can preliminarily filter the incoming air to some extent, intercepting some large-particle dust and other pollutants.

[0034] A air outlet 3 is arranged on the baffle 1 and communicates with the inside of the baffle 1. The air outlet 3 is arranged on the left side of the baffle 1, on the upper side of the baffle 1, on the left side of the baffle 1 and on the upper side of the baffle 1, and the opening is arranged upward. This position design has its rationality. The air outlet is arranged on the left side of the upper side, which is convenient for connecting with the air suction pipe of the external air suction device. The upward design of the opening is conducive to the smooth entry of the discharged air into the air suction pipe, avoiding problems such as air backflow.

[0035] The air outlet 3 is a tubular structure, and the air outlet 3 is arranged with the opening upward. The diameter of the air outlet 3 is greater than the thickness of the baffle 1, and the air outlet 3 is a tubular structure and its diameter is greater than the thickness of the baffle 1. The tubular structure helps better docking with the air suction pipe, ensuring the sealing and stability of the connection. The diameter greater than the thickness of the baffle 1 can ensure sufficient air flow, avoid poor air discharge due to too small air outlet, and affect the working efficiency of the entire air suction device.

[0036] When the air suction device is connected with the air outlet 3 and starts to work, due to the suction force generated by the air suction device, air will enter the inside of the baffle 1 from the air inlet 2. Harmful gases, dust and other pollutants generated in the desktop area will be sucked into the air inlet along with the air flow. The air flows in the hollow channel inside the baffle, and then is discharged from the air outlet 3. In this way, the desktop area can be targeted for air purification. This design can effectively capture and handle harmful substances generated during the use of the experimental table, ensuring the air quality around the desktop.

[0037] The device as a whole is a baffle structure, which not only has the function of air purification, but also can be used as a baffle on the table. This can play a certain protective role in experimental operation, such as preventing experimental materials from falling accidentally, or blocking some splashed liquids to some extent.

[0038] The structure mainly consists of a baffle, an air inlet, an air outlet and an air inlet net cover, without too many mechanical parts or electronic elements. This simple structure makes the installation, operation and maintenance of the device very convenient.

[0039] The original baffle structure is ingeniously utilized, reducing additional materials and complex design requirements. During manufacturing, no special high-precision processing or expensive raw materials are required, effectively reducing manufacturing costs and making it more market competitive, suitable for widespread promotion and application in various laboratories.

[0040] An experimental table provided with an air suction device, comprising a frame body 6, a tabletop panel 7 is fixedly arranged on the upper side of the frame body 6, and the air suction device is fixedly arranged on the frame body 6 and located at the rear side of the tabletop panel 7. The bottom of the baffle 1 is provided with a positioning connecting strip 5 along the length direction thereof, and the frame body 6 is provided with a positioning connecting groove 8 connected with the positioning connecting strip 5, the positioning connecting strip 5 is connected with the positioning connecting groove 8, and the connection is further fixed by glue or screws.

[0041] The frame body 6 provides a stable foundation as the supporting structure of the entire experimental table. The tabletop panel 7 is fixedly arranged on the upper side of the frame body 6 and is the main plane for experimental operation. This structure is common in laboratory furniture and can withstand a certain weight, suitable for placing experimental instruments and materials.

[0042] The air suction device is fixedly arranged on the frame body 6 and located at the rear side of the tabletop panel 7. Placing the air suction device in this position has many advantages. First, it does not occupy the operation space of the tabletop panel 7, ensuring that the experimental personnel have enough space for experimental operation. Second, harmful gases and dust generated during the experiment tend to spread upwards and backwards, and the air suction device at the rear side of the tabletop panel 7 can more effectively capture these pollutants.

[0043] The positioning connecting strip 5 at the bottom of the baffle 1 and the positioning connecting groove 8 on the frame body 6 constitute the main connecting structure.

[0044] The positioning connecting strip 5 is arranged along the length direction of the baffle 1, which ensures the stability and straightness of the connection between the baffle 1 and the frame body 6.

[0045] The positioning connecting groove 8 cooperates with the positioning connecting strip 5 to achieve preliminary positioning and installation. On this basis, further fixed connection is achieved by glue or screws, further enhancing the firmness of the connection. Gluing can fill the small gaps at the connection site to prevent loosening, while screwing provides strong mechanical connection force to ensure that the baffle does not separate from the frame body due to vibration and other factors during operation of the air suction device.

[0046] When harmful gases or dust are generated on the desktop panel 7 during experimental operations, the air suction device located at the back side of the desktop panel 7 starts working. Air enters the air suction device (inside the baffle 1) from the air inlet 2 on the front side of the baffle 1, and then is discharged through the air outlet 3. In this process, harmful gases and dust are sucked in and discharged, thereby purifying the air environment around the desktop panel 7 and ensuring the health of the experimental personnel and the normal operation of the experimental operation.

[0047] Good stability:

[0048] The air suction device is fixed on the frame 6 by the positioning connection strip 5 and the positioning connection groove 8, as well as the auxiliary fixing of glue or screws. This connection mode ensures the stability of the air suction device during operation. The stable air suction device can more effectively play its purification function and will not affect the air suction and discharge efficiency due to the shaking of the device.

[0049] Easy to install:

[0050] The design of the positioning connection strip 5 and the positioning connection groove 8 simplifies the installation process of the air suction device. During installation, only need to align the positioning connection strip 5 with the positioning connection groove 8 and insert it, and then perform simple glueing or screw fixing to complete the installation. This installation method does not require complex adjustment and calibration, saving installation time and labor cost.

[0051] Rational use of space:

[0052] The air suction device is located at the back side of the desktop panel 7, which does not affect the normal use of the desktop panel 7, and can fully utilize the space of the experimental table to realize the air purification function. The rational space layout makes the experimental table have the purification function while still maintaining good operation convenience.

[0053] The air outlet 3 is provided with activated carbon 9. The activated carbon 9 is arranged in the air outlet 3. The air outlet 3 itself is a tubular structure and the opening faces upward, and this arrangement makes the air flowing out from the inside of the baffle 1 have to pass through the activated carbon 9. When the air flows out from the inside of the baffle 1 through the air outlet 3, the peculiar smell, harmful gas and the like that may be carried therein will contact the activated carbon 9. The activated carbon has a highly developed pore structure, and this special structure makes it have strong adsorption capacity. It can adsorb the peculiar smell molecules, residual harmful chemical substances and the like in the air on the pore surface through physical adsorption. For example, for volatile organic compounds (VOCs) generated in the experimental process, such as formaldehyde, benzene and the like, the activated carbon can effectively capture them to prevent them from entering the laboratory environment again with the discharged air. By arranging the activated carbon 9 in the air outlet 3, the air purification effect is significantly improved without increasing the overall complexity of the device. It can perform secondary treatment on the air passing through the air suction device, further remove the pollutants therein, and ensure that the discharged air is cleaner and odorless, thereby ensuring the air quality of the laboratory. The activated carbon is a relatively low-cost and easily accessible material. Its application in the air outlet 3 realizes good air purification function at low cost without using complex air purification technology. This design ensures the air purification effect while meeting the cost control requirements, which is helpful for the promotion and application of the experimental table air suction device in the market. The activated carbon 9 is arranged in the air outlet 3, and when it needs to be replaced, the operation is relatively simple. Since the structure of the air outlet 3 is relatively simple and easy to access, the activated carbon can be conveniently replaced by the staff on a regular basis to ensure the sustainability of its adsorption effect.

[0054] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
