The existing gas collection devices have the following disadvantages:

[0003] 1. Lack of lifting function: Odor collection devices are usually designed as fixed structures and cannot be raised or lowered according to changes in the height or position of the odor source. This limits the applicability of the device in different scenarios, especially when the collection height needs to be adjusted frequently.

[0004] 2. Low collection efficiency: Existing odor collection systems may not be able to efficiently collect low-concentration or dispersed odors due to design or structural limitations, which leads to poor treatment effects and may not be able to completely eliminate odor pollution.

[0005] 3. Insufficient negative pressure generation: Although the existing odor collection devices use high-power centrifugal fans, they still cannot generate enough negative pressure to effectively extract odor, which reduces the efficiency of odor collection and may increase energy consumption.

[0029] See also Figure 1 The preferred embodiment of the utility model provides a liftable gas collection device, including a gas collection hood 1, a telescopic tube 2, a gas collection pipe 3, a guide assembly 4 and a driving member 5. The telescopic tube 2 is connected between the gas collection hood 1 and the gas collection pipe 3. The deformation direction of the telescopic tube 2 is the same as the moving direction of the guide assembly 4. The gas collection hood 1 is connected to the guide assembly 4. The driving member 5 can drive the guide assembly 4 to move up and down, thereby driving the gas collection hood 1 to move up and down, and then compressing or stretching the telescopic tube 2. Since the driving member 5 can drive the guide assembly 4 to move up and down, thereby driving the gas collection hood 1 to move up and down, and then compressing or stretching the telescopic tube 2, the gas collection device has a lifting function, and by starting the driving member 5, the gas collection hood 1 is adjusted to the most suitable height for absorbing odor, which can improve the collection efficiency. The improvement of the gas collection efficiency reduces the power requirement of the centrifuge, and the negative pressure generated by the lower power centrifuge is also sufficient for collecting odor. The liftable gas collection device provided by the utility model only uses one driving member 5, and the driving member 5 only needs to have the function of adjusting the lifting, and the structure is simple, the maintenance cost is low and the maintenance process is simple.

[0030] The guide assembly 4 includes a first fixed rod 41, which is hollow. The driving member 5 includes an actuator 51 and a push rod 52. The push rod 52 is inserted through the first fixed rod 41 and is slidably connected to the first fixed rod 41. One end of the push rod 52 is connected to the actuator 51, and the other end is connected to the air collecting hood 1. The first fixed rod 41 guides the push rod 52 to ensure the stability of the lifting and lowering movement of the air collecting hood 1 driven by the push rod 52.

[0031] The guide assembly 4 also includes a second fixed rod 42, a slider 43 and a guide rail 44. The second fixed rod 42 and the guide rail 44 are arranged in the same direction. The slider 43 is fixedly connected to the second fixed rod 42. The slider 43 is slidably connected to the guide rail 44. The guide rail 44 is connected to the air collecting hood 1 relative to the end away from the second fixed rod 42. The combination of the second fixed rod 42 and the guide rail 44 further guides the lifting and lowering movement of the air collecting hood 1 to ensure its stability.

[0032] The push rod 52 and the guide rail 44 are connected to the opposite sides of the air collecting hood 1, the telescopic tube 2 is located between the guide rail 44 and the push rod 52, and the telescopic tube 2 and the air collecting hood 1 are connected to the middle part of the guide assembly 4 composed of the push rod 52 and the guide rail 44. When lifting, the air collecting hood 1 is prevented from tipping over due to unstable center of gravity and the telescopic tube 2 is prevented from tilting.

[0033] The gas collecting pipe 3 includes a first connecting pipe 31, a guide pipe 32 and a second connecting pipe 33. The first connecting pipe 31 and the second connecting pipe 33 are arranged perpendicular to each other. The guide pipe 32 is obliquely connected between the first connecting pipe 31 and the second connecting pipe 33. The first connecting pipe 31 is connected to the telescopic pipe 2 at one end away from the guide pipe 32. This arrangement reduces the resistance encountered by the gas when it flows to the bend due to the arrangement of the guide pipe 32, making it easier to pass through and facilitating the discharge of the gas.

[0034] The liftable gas collecting device also includes a pipe support 6, which includes a support plate 62 and two limiting rods 61 arranged opposite to each other. The three are connected in a U shape. The second connecting pipe 33 is clamped between the two limiting rods 61 and abuts against the support plate 62. The U-shaped pipe support 6 formed by the two limiting rods 61 and the support plate 62 provides support for the second connecting pipe 33, fixes the second connecting pipe 33, and facilitates the second connecting pipe 33 to discharge gas to a designated position.

[0035] The liftable gas collecting device further comprises two support rods 7 , and the first connecting pipe 31 is fixed between the two support rods 7 . The two support rods 7 fix the first connecting pipe 31 to prevent the first connecting pipe 31 from shifting.

[0036] The gas collecting hood 1 is conical, and the end with a smaller cross-sectional area is connected to the telescopic tube 2, and the other end is used to collect gas. The end port of the gas collecting hood 1 for inputting gas is larger, which can inhale more gas and improve the gas collection efficiency.

[0037] The cross section of the gas collecting pipe 3 is square, which is easier to fix and prevents the gas collecting pipe 3 from shifting when the gas passes through the gas collecting pipe 3 .

[0038] The telescopic pipe 2 is connected to the gas collecting pipe 3 and the gas collecting hood 1 through flanges. The flange connection is easy to disassemble, has high strength and good sealing performance.

[0039] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
