Technical Field
[0001] The utility model relates to the technical field of student desks, in particular to a new type of integrated ventilated student desk. Background Art
[0002] In the context of current technological development, laboratories, as important places for scientific research and education and teaching, the internal air quality is directly related to the health and safety of experimental personnel. Especially when conducting chemical reaction experiments, harmful gas emissions often occur. Traditional laboratory air purification solutions mainly rely on centralized air purification systems. This system captures and filters harmful gases that have diffused into the air through a central purifier arranged at the top of the laboratory. However, this mode has significant deficiencies. First, since harmful gases have been widely distributed inside the laboratory before reaching the purifier, experimental personnel are inevitably exposed to a harmful environment during the process of waiting for the purification effect to appear, increasing the risk of health damage. Second, the centralized purification system reacts slowly to the uneven distribution of gases, making it difficult to achieve immediate and efficient local purification, and having high energy consumption. In addition, traditional centralized air purification systems often use filter materials with a single configuration in design. This fixed design limits the adaptability of the system to diverse chemical reaction experimental environments. Different chemical reactions may produce completely different harmful gases, and the chemical properties, toxicity, and adsorption mechanisms of each gas are different, requiring filter materials to have a high degree of selectivity and flexibility. However, single filter materials are difficult to accurately match the possible harmful gases, resulting in a significant reduction in air purification effect in some specific experimental scenarios and even the occurrence of secondary pollution.

[0035] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.
[0037] In the wave of current scientific and technological development, as the core of scientific research and teaching, the air quality in laboratories is related to the health of personnel and the safety of experiments. For the harmful gases released in chemical reaction experiments, traditional centralized air purification systems face challenges: First, the purification is lagging. The harmful gases are widely dispersed before being treated, increasing the risk of personnel exposure; Second, the purification efficiency and uniformity are insufficient. It is difficult to quickly respond to local pollution, and the energy consumption is relatively high; Third, the singularity of filter material configuration makes it difficult to meet the specific needs of different harmful gases in diverse chemical experiments, affecting the purification effect and even possibly causing secondary pollution.
[0038] To solve the above problems, please refer to Figures 1 to 10, an embodiment of the present utility model provides a novel integrated ventilation student desk, which includes a table frame main body 10 and a supporting desktop 20 installed on the table frame main body 10. The supporting desktop 20 provides a stable experimental operation platform. A storage box 21 is integrated on one side of the supporting desktop 20. An air suction member 30 with adjustable position and angle is arranged in the storage box 21. A universal joint corrugated pipe 40 is installed at the air outlet end of the air suction member 30. One end of the universal joint corrugated pipe 40 passes through the storage box 21 and is connected to a suction ventilation device. The flexible bending and extension ability of the universal joint corrugated pipe 40 not only meets the flexible adjustment of the position and angle of the air suction member 30, but also ensures the unobstructed flow of air. During the experiment, the operator can accurately align the experimental reaction site by adjusting the position and angle of the air suction member 30, realizing instant and efficient local purification, and avoiding the significant diffusion of harmful gases, which increases the health risk of experimental personnel. At the same time, the air suction member 30 performs centralized local purification according to needs, and compared with the continuous operation of the traditional centralized purification system, the energy consumption is lower. A detachable filter element mounting rack 50 is arranged inside the air suction member 30, and a plurality of purification filter elements 70 are detachably installed on the filter element mounting rack 50. The detachable design meets the daily replacement and maintenance requirements, and the synergistic effect of the plurality of purification filter elements 70 effectively absorbs and neutralizes harmful substances in the gas. Among them, the plurality of purification filter elements 70 are all purification filter elements 70 for the same kind of harmful gas. In another solution, the plurality of purification filter elements 70 include purification filter elements 70 for different kinds of harmful gases, improving the adaptability to diverse chemical reaction experimental environments. For details, please refer to Figure 10 , the plurality of purification filter elements 70 are arranged at intervals in parallel, increasing the contact between the air flow and the purification filter elements 70, and improving the purification efficiency. A plurality of ventilation slots 71 are arranged at intervals on each purification filter element 70. Please refer to Figure 7 and Figure 8 , the ventilation slots 71 on two adjacent purification filter elements 70 are arranged in a staggered and complementary manner, further improving the comprehensiveness and meticulousness of purification while ensuring air circulation.
[0039] In this embodiment, please refer to Figure 4 , the air suction member 30 includes a wind hood housing 31 and a ventilation hood 32 detachably installed on the wind hood housing 31, which is convenient for maintenance and cleaning, as well as the replacement of the purification filter element 70, improving the flexibility and use efficiency of the equipment. A negative pressure chamber 311 is opened in the wind hood housing 31, and the universal joint corrugated pipe 40 is communicated with the negative pressure chamber 311. The setting of the negative pressure chamber 311 ensures the high efficiency of air flow, effectively gathers and guides the air flow. A plurality of support mounting columns 60 protrude from the bottom of the negative pressure chamber 311, and the filter element mounting rack 50 is detachably installed on the support mounting columns 60, simplifying the filter element replacement process and reducing the maintenance cost. The purification filter element 70 is installed at the air inlet end of the negative pressure chamber 311 through the filter element mounting rack 50, effectively purifying the harmful components in the gas, avoiding secondary pollution, and ensuring the cleanliness and efficiency of the subsequent treatment process.
[0040] Please refer to Figure 5 , the bracket mounting post 60 includes a support post 61 and a mounting portion 62. One end of the support post 61 is fixedly mounted on the wind hood housing 31, providing a solid support foundation for the entire mounting structure and ensuring the stability and reliability of the mounting. The other end of the support post 61 is fixedly mounted with the mounting portion 62. The diameter of the mounting portion 62 is smaller than that of the support post 61. The purification filter 70 is detachably mounted on the mounting portion 62 through the filter mounting frame 50.
[0041] It should be noted that the difference in the diameter dimensions between the mounting portion 62 and the support post 61 is for facilitating the precise docking and installation of the filter mounting frame 50, further improving the maintenance efficiency and the flexibility of installation and replacement.
[0042] Please refer to Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10 , the filter mounting frame 50 includes a bottom support frame 51, a first spacer 52, a middle support frame 53, a second spacer 54, and a top fixing frame 55 that are sequentially mounted on the mounting portion 62, forming a stable and multi-level support structure. Purification filters 70 are clamped between the bottom support frame 51 and the first spacer 52 and between the middle support frame 53 and the second spacer 54. The purification filters 70 are sleeved and mounted on the mounting portion 62. A fastener 56 is also mounted at one end of the mounting portion 62 away from the support post 61. The fastener 56 abuts against the side of the top fixing frame 55 away from the middle support frame 53, realizing further fixing and pressing of each purification filter 70 and ensuring the stability and reliability of the purification filter 70 under high-speed air flow.
[0043] It should be noted that the bottom support frame 51, as the starting point for the installation of the purification filter 70, not only provides a stable support platform but also ensures the accuracy of the initial position of the bottom purification filter 70 during installation. The addition of the first spacer 52 effectively isolates the direct contact between the purification filter 70 and the middle support frame 53, preventing potential friction damage while ensuring fluidity. The combination of the middle support frame 53 and the second spacer 54 realizes the installation and fixation of another purification filter 70, while avoiding the direct contact between the purification filter 70 and the top fixing frame 55, preventing potential friction damage. The overhead setting method ensures air circulation. The design of the double purification filters 70 improves the purification efficiency and also meets the requirements of diverse chemical experiment reaction scenarios. Different purification filters 70 can be combined and installed to adsorb and neutralize harmful substances in the gas.
[0044] Furthermore, please refer to Figure 10A first ventilation gap 57 is provided between the two purification filters 70, and a second ventilation gap 58 is provided between the top fixing frame 55 and the purification filter 70 close to the second isolation member 54. The setting of the double ventilation gaps not only provides an additional circulation channel for the air, but also further increases the contact area between the airflow and the purification filter 70, thereby improving the purification efficiency, and avoiding high-frequency vibration friction of the purification filter 70 under the influence of high-speed airflow, thereby causing damage to the purification filter 70, thereby extending the service life of the purification filter 70.
[0045] See also Figure 5 The mounting portion 62 includes a first column 621, a second column 622 and a third column 623. The first column 621, the second column 622, the third column 623 and the support column 61 are connected in sequence. The diameters of the first column 621, the second column 622, the third column 623 and the support column 61 increase in sequence. Please refer to Figure 4 and Figure 10 The bottom support frame 51 and the first isolating member 52 are sleeved and installed on the third column 623, the middle support frame 53 and the second isolating member 54 are sleeved and installed on the second column 622, the top fixing frame 55 is sleeved and installed on the first column 621, the fastener 56 is screwed and installed on the first column 621, and is in contact with the top fixing frame 55. A first mounting through hole 72 adapted to the third column 623 is provided on the purification filter 70 arranged between the bottom support frame 51 and the first isolating member 52, and a second mounting through hole 73 adapted to the second column 622 is provided on the purification filter 70 arranged between the middle support frame 53 and the second isolating member 54. The opening of the first mounting through hole 72 and the second mounting through hole 73 realizes the close fit between the purification filter 70 and the mounting portion 62, thereby improving the installation accuracy and efficiency.
[0046] The bottom support frame 51 is provided with a third mounting through hole 511 adapted to the third column 623. The bottom support frame 51 is closely matched with the third column 623 through the third mounting through hole 511, which effectively prevents the bottom support frame 51 from sliding and deflecting during the installation process. The middle support frame 53 is provided with a fourth mounting through hole 531 adapted to the second column 622, which is convenient for the installation and positioning of the middle support frame 53, and realizes the stable support of the purification filter 70 in the middle. The top fixing frame 55 is provided with a fifth mounting through hole 551 adapted to the first column 621. The top fixing effect of the entire mounting frame is enhanced through the close match between the fifth mounting through hole 551 and the first column 621. The stability of the top fixing frame 55, as the last line of defense of the entire mounting frame, is directly related to the stability and reliability of the purification filter 70 under high-speed airflow.
[0047] For further information, see Figures 4 to 6, an air outlet 312 is provided on one side of the air hood housing 31. The air outlet 312 is connected to the universal corrugated pipe 40, ensuring the smooth discharge of air flow. An operation handle 313 is provided on the side of the air hood housing 31 away from the air outlet 312, facilitating the user to take out the air suction member 30 from the storage box 21 and easily move or adjust the position and angle of the air suction member 30, enhancing the convenience and practicality of the device.
[0048] The ventilation hood 32 is snap-connected to the air hood housing 31, which not only simplifies the installation steps but also improves the installation stability and sealing performance. A disassembly convex block 321 is provided on one side of the ventilation hood 32, and an avoidance arc groove 314 corresponding to the disassembly convex block 321 is provided on the air hood housing 31. This design makes the disassembly and installation of the ventilation hood 32 extremely easy, providing great convenience for users to perform maintenance operations such as cleaning or replacing the purification filter element 70.
[0049] Please refer to Figure 3 , an avoidance through hole 211 corresponding to the universal corrugated pipe 40 is provided on the side wall of the storage box 21, facilitating the threading and installation of the universal corrugated pipe 40. A cover plate 22 is also rotatably installed on the side of the storage box 21 away from the support tabletop 20. This design enables the air suction member 30 provided in the storage box 21 to be protected from dust and other pollutants when not in use, extending the service life of the air suction member 30 and enhancing the overall aesthetics of the student desk.
