Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically a gas circulation device for laboratory air purification. Background Technology

[0002] Laboratory air purification is primarily used to provide a stable, clean working environment that meets specific requirements. During experiments, dust, bacteria, viruses, and other microorganisms, as well as harmful gases and particulate matter in the air, can interfere with experimental results and even pose a threat to the health of laboratory personnel. Air purification effectively removes these contaminants, ensuring the accuracy and reliability of experimental data. Simultaneously, air purification helps control temperature, humidity, and airflow within the laboratory, providing a more stable environmental condition and thus improving the success rate and efficiency of experiments.

[0003] Existing laboratories typically contain key areas requiring special purification and relatively general purification areas. However, under current technological conditions, achieving clearly defined zoning purification of these two areas, followed by unified air circulation, presents significant challenges. Key areas may involve high-precision experiments or sensitive sample processing, requiring more efficient and higher-volume air purification measures; while general areas may only need to meet basic cleanliness requirements. To technically achieve this organic combination of zoning purification and unified circulation, we propose a gas circulation device for laboratory air purification. Utility Model Content

[0009] An airflow control component is provided, which is located in the second partition and has a closed plate inside. It works in conjunction with the circulation component to control the airflow.

[0014] The second connecting pipe is fixedly connected between the first air duct and the wall, and is connected to the first air duct.

[0015] Two bends are respectively fixedly connected to the inner ends of the first air duct and the second air duct;

[0016] The two air boxes are respectively fixedly connected to the outer ends of the first air duct and the second air duct. Each of the two air boxes is fixedly equipped with a driving fan. The two driving fans drive in opposite directions and can respectively realize air intake and air exhaust.

[0017] Preferably, multiple air vents are provided at the bottom of both the first and second connecting pipes.

[0018] Preferably, the circulation components are configured in four groups, the number of which corresponds to the four walls.

[0019] Preferably, the first connecting pipe and the second connecting pipe are configured as four groups, and each group of the first connecting pipes is connected to the adjacent group of the second connecting pipes, and the four groups of the first connecting pipes and the second connecting pipes are connected as a whole.

[0020] Preferably, each of the four inner walls is fixedly connected to two electric push rods, which are divided into four groups. The drive end of each of the four groups of electric push rods is fixedly connected to a baffle. Each of the four groups of baffles can slide into the first connecting pipe and cut off the connection between the first connecting pipe and the adjacent second connecting pipe.

[0021] Preferably, the airflow control component includes:

[0022] The outer cylinder is fixedly connected within the second partition.

[0023] An inner cylinder is disposed inside an outer cylinder, and multiple support rods are fixedly connected between the outer cylinder and the inner cylinder.

[0024] A gear ring is rotatably connected to the top of the inner cylinder, and multiple gear blocks are fixedly connected to both the inside and outside of the gear ring;

[0025] The four internal gears are rotatably connected to the bottom of the inner cylinder, and all four internal gears are meshed with the inner side of the gear ring. The top of each of the four internal gears is higher than the gear ring.

[0026] The motor is fixedly connected to the outside of the inner cylinder, and a drive gear is fixedly connected to the drive end of the motor. The drive gear meshes with the outer side of the gear ring.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] 1. By setting up a circulation component, the drive fans located in the air boxes at the outer ends of the four first air ducts are started to rotate, thereby achieving air intake. Fresh air enters the second section through the four first air ducts. During this process, some fresh air will be dispersed into the four first zones through the air outlets at the bottom of the four sets of first and second connecting pipes. Then, the drive fans located in the air boxes at the outer ends of the four second air ducts are started to rotate. Since the drive fans at this position drive in the opposite direction to the drive fans that achieve air intake, air exhaust can be achieved, drawing out the air from the first and second zones. In summary, air circulation and purification can be achieved.

[0030] 2. Since one end of each of the four sets of first and second air ducts is located in the second zone, and each first zone is only equipped with one set of first and second air ducts, the key purification of the second zone and the general purification of the four first zones can be achieved.

[0031] 3. In addition, by activating four sets of electric push rods, four sets of baffles are driven to cut off the connection channels between the four sets of first and second connecting pipes. In this way, the four first zones can be separated to avoid mutual contamination. Conversely, the four sets of first zones can be integrated into a whole for cyclical purification.

[0032] 4. By setting the air volume control component and starting the motor, the motor drives the drive gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives the four internal gears to rotate, which in turn drives the four closed plates to move inward and outward respectively. This can adjust the size of the four sets of bend openings, so as to adjust the air volume in the second zone. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] like Figure 1-6 As shown, in this embodiment, a gas circulation device for laboratory air purification includes: a wall 100, a circulation component 200, and an air volume control component 300. The four walls 100 are combined into a whole, and each of the four walls 100 is divided into a first partition 110. The four walls 100 are separated into a second partition 120. The second partition 120 is a key purification area, while the four first partitions 110 are general purification areas.

[0043] The circulation assembly 200 includes: a first duct 210, a second duct 220, a first connecting pipe 230, a second connecting pipe 240, a bend 250, and an air box 260. The first duct 210 is located at the top of the wall 100, with both ends of the first duct 210 extending out of the wall 100. The second duct 220 is located at the top of the wall 100, with both ends of the second duct 220 extending out of the wall 100. The two first connecting pipes 230 are fixedly connected between the first duct 210 and the second duct 220, and are in communication with the first duct 210 and the second duct 220. The two second connecting pipes 240 are fixedly connected between the first duct 210 and the wall 100, and are in communication with the first duct 210. The bottom of each of the two first connecting pipes 230 and the second connecting pipe 240 is provided with multiple air vents 270, and each of the multiple air vents 270 is provided with a filter screen to filter the air. This is prior art and will not be described in detail.

[0044] Two bends 250 are fixedly connected to the inner ends of the first duct 210 and the second duct 220, respectively; two air boxes 260 are fixedly connected to the outer ends of the first duct 210 and the second duct 220, respectively. A drive fan 261 is fixedly installed inside each air box 260. The two drive fans 261 drive in opposite directions, enabling them to respectively intake and exhaust air. When the drive fans 261 located inside the air boxes 260 at the outer ends of the four first ducts 210 are started, air intake is achieved, and fresh air enters the second section through the four first ducts 210. During this process, a portion of the fresh air will be dispersed into the four first zones 110 through the air vents 270 at the bottom of the four sets of first connecting pipes 230 and second connecting pipes 240. Then, the drive fan 261 located at the outer end of the air box 260 of the four second air ducts 220 will be started to rotate. Since the drive fan 261 at this position is driven in the opposite direction to the drive fan 261 that realizes air intake, air can be exhausted, and the air in the first zone 110 and the second zone 120 can be extracted. In summary, air circulation and purification can be achieved.

[0045] In this embodiment, two electric push rods 280 are fixedly connected to the inner sides of each of the four walls 100. These are divided into four groups. Each of the four groups of electric push rods 280 has a baffle 281 fixedly connected to its driving end. All four baffles 281 can slide into the first connecting pipe 230, which can cut off the connection between the first connecting pipe 230 and the adjacent second connecting pipe 240. When the four groups of electric push rods 280 are activated, the four groups of baffles 281 are driven to cut off the connection channel between the four groups of first connecting pipes 230 and second connecting pipes 240. In this way, the four first partitions 110 can be separated to avoid mutual contamination. Conversely, the four groups of first partitions 110 can be integrated into a whole for cyclic purification.

[0046] Specifically, since one end of each of the four sets of first air ducts 210 and second air ducts 220 is located in the second zone 120, and each first zone 110 is only equipped with one set of first air ducts 210 and second air ducts 220, the key purification of the second zone 120 and the general purification of the four first zones 110 can be achieved.

[0047] Example 2

[0048] Based on Embodiment 1, an air volume control component 300 is provided to adjust the air volume in the second partition 120.

[0049] like Figure 3-6 As shown, in this embodiment, the airflow control component 300 includes: an outer cylinder 310, an inner cylinder 320, a gear ring 330, internal gears 340, a motor 350, and a closing plate 360. The outer cylinder 310 is fixedly connected within the second partition 120; the inner cylinder 320 is disposed within the outer cylinder 310, and multiple support rods 321 are fixedly connected between the outer cylinder 310 and the inner cylinder 320; the gear ring 330 is rotatably connected to the top of the inner cylinder 320, and multiple tooth blocks 331 are fixedly connected to both the inner and outer sides of the gear ring 330; four internal gears 340 are rotatably connected to the inner bottom of the inner cylinder 320, and all four internal gears 340 mesh with the inner side of the gear ring 330, with the top positions of the four internal gears 340 higher than the gear ring 330; the motor 350 is fixedly connected to the outer cylinder 320. The drive end of the motor 350 is fixedly connected to a drive gear 351, which meshes with the outer side of the gear ring 330. Four closing plates 360 are all located on the top of the gear ring 330, and toothed plates 361 are fixedly connected to the bottom of each of the four closing plates 360. The four toothed plates 361 are slidably connected to the top surface of the gear ring 330, and mesh with four internal gears 340 respectively. The four closing plates 360 correspond to four sets of bent tubes 250 and are slidably located at the bottom openings of the bent tubes 250. It should be noted that the bottoms of the four toothed plates 361 can be slidably connected to the top of the gear ring 330 via slide rails to prevent offset while not interfering with the meshing rotation of the gear ring 330. The slide rails are existing technology and will not be described in detail.

[0050] Specifically, the motor 350 is started, which drives the drive gear 351 to rotate, which in turn drives the gear ring 330 to rotate. The gear ring 330 drives the four internal gears 340 to rotate, which in turn drives the four closed plates 360 to move inward and outward respectively. This can adjust the size of the openings of the four sets of bends 250, so as to adjust the air volume in the second zone 120.

[0051] Working principle: First, the drive fans 261 located in the outer air boxes 260 of the four first air ducts 210 are started to rotate, realizing air intake. Fresh air enters the second section through the four first air ducts 210. During this process, some fresh air will be dispersed into the four first partitions 110 through the air outlets 270 at the bottom of the four sets of first connecting pipes 230 and second connecting pipes 240. Then, the drive fans 261 located in the outer air boxes 260 of the four second air ducts 220 are started to rotate. Since the drive fans 261 at this position drive in the opposite direction to the drive fans 261 that realize air intake, air exhaust can be realized, drawing air out of the first partitions 110 and the second partitions 120. In summary, air circulation and purification can be achieved. Since one end of each of the four sets of first air ducts 210 and second air ducts 220 is located in the second partition 120, and each first partition... Each zone 110 is equipped with only one set of first duct 210 and second duct 220. Therefore, it can achieve key purification of the second zone 120 and general purification of the four first zones 110. In addition, by activating four sets of electric push rods 280, four sets of baffles 281 are driven to cut off the connecting channels between the four sets of first connecting pipes 230 and second connecting pipes 240. In this way, the four first zones 110 can be separated to avoid cross-contamination. Conversely, the four sets of first zones 110 can be integrated into a whole for cyclic purification. In addition, by activating the motor 350, the motor 350 drives the drive gear 351 to rotate, which in turn drives the gear ring 330 to rotate. The gear ring 330 drives the four internal gears 340 to rotate, which drives the four closed plates 360 to move inward and outward respectively. This can adjust the size of the opening of the four sets of bends 250 to adjust the air volume in the second zone 120.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
