Technical Field
[0001] This utility model relates to the field of air purification technology, and in particular to an air purification device for medical cleanrooms. Background Technology
[0002] Cleanrooms for producing medical equipment have high requirements for rapid air exchange and dust prevention. In existing air purification devices, the components used to achieve dust prevention are usually filters. After a period of use, the filters need to be manually cleaned or replaced, which not only causes inconvenience to users, but also easily causes secondary pollution to the factory during cleaning and replacement.

[0034] Please see Figures 1 to 5 This utility model provides an air purification device for medical cleanrooms, including a main sleeve 1, an air intake pipe 2, an exhaust pipe 3, a cleaning component 4, an air intake component 5, and a filter plate 6.
[0035] The main sleeve 1 is a rectangular central control cylinder with an air intake pipe 2 and an exhaust pipe 3 respectively at its two horizontal ends. In this embodiment, the air intake pipe 2 is located on the left side of the main sleeve 1, and the exhaust pipe 3 is located on the right side of the main sleeve 1. The filter plate 6 is fixedly connected inside the main sleeve 1 on the side near the exhaust pipe 3.
[0036] The bottom of the main sleeve 1 has a dust removal port 11 near the filter plate 6, and a T-shaped groove 12 is formed at the dust removal port 11. The dust removal port 11 is used to discharge dust, and the T-shaped groove 12 is used to install the collection box 45 below.
[0037] A support plate 13 is fixedly connected to the inner wall of the main sleeve 1 near the exhaust pipe 3 to provide support for the cleaning block drive shaft 42. A motor mounting plate 14 is fixedly connected to the top of the main sleeve 1 near the suction pipe 2 to mount the motor 51.
[0038] The cleaning assembly 4 includes a cleaning block 41, a cleaning block drive shaft 42, a crank 43, a connecting rod 44, and a collection box 45.
[0039] One side of the cleaning block 41 is attached to the front of the filter plate 6 and is used to wipe the dust on the front of the filter plate 6.
[0040] The cleaning block drive shaft 42 is horizontally arranged along the length of the main sleeve 1 and rotatably connected to the inner wall of the main sleeve 1. Specifically, the cleaning block drive shaft 42 is mounted on the support plate 13 via bearings.
[0041] A fourth bevel gear 48 is mounted on one end of the cleaning block drive shaft 42, and the other end is fixedly connected to one end 43 of a crank. The other end of the crank 43 is hinged to a connecting rod 44, and the other end of the connecting rod is hinged to the cleaning block 41. The crank 43, connecting rod 44, and cleaning block 41 together form a crank-slider mechanism, which converts the rotation of the cleaning block drive shaft 42 into the reciprocating motion of the cleaning block 41, thereby wiping the front and side surfaces of the filter plate 6. The fourth bevel gear 48 is used to transmit power to the cleaning block drive shaft 42.
[0042] The collection box 45 is used to collect the dust discharged from the dust removal port 11. The top of the collection box 45 is turned up to both sides, and the turned-up edges correspond exactly to the shape and size of the T-shaped groove 12. The collection box 45 is connected to the T-shaped groove 12 by sliding insertion.
[0043] The air intake assembly 5 includes a motor 51, a first fan 52, and a second fan 54.
[0044] The first fan 52 is located below the main sleeve 1. The shaft of the first fan 52 is vertically oriented, extending through the bottom surface of the main sleeve 1 and into its interior, and is rotatably connected to the bottom and top surfaces of the main sleeve 1. A first bevel gear 53 is mounted on the shaft of the first fan 52. A protective cover 59 is installed on the outside of the first fan 52.
[0045] The second fan 54 is located inside the main sleeve near the intake pipe. The shaft of the second fan 54 is horizontally positioned and equipped with a second bevel gear 55.
[0046] The second bevel gear 54 and the third bevel gear 48 mesh with the first bevel gear 52. When the first fan 52 rotates, it can drive the second fan 54 and the cleaning block drive shaft 42 to rotate. The motor 51 is used to drive the first fan 52 to rotate.
[0047] In this embodiment, there are two first fans 52, and a drive shaft 56 is provided between the two first fans. The drive shaft 56 is a two-section split shaft, which is connected and fixed in the middle by a coupling plate 58. Fourth bevel gears 57 are respectively installed at the left and right ends of the drive shaft 56. The two fourth bevel gears 57 mesh with the first bevel gears 53 on the rotating shafts of the two first fans 52, respectively, to make the two first fans 52 rotate synchronously.
[0048] The motor 51 is mounted on the motor mounting plate 14. The output shaft of the motor 51 is connected to the shaft of the first fan 52 near the intake pipe 2. The second bevel gear 55 meshes with the first bevel gear 53 near the intake pipe 2. The third bevel gear 48 meshes with the first bevel gear 53 near the exhaust pipe 3.
[0049] It should be noted that in other embodiments, the user can select the number of first fans 52 according to the usage requirements of the factory. There can be one or more first fans 52. When there is only one first fan 52, the second fan 54 and the cleaning block drive shaft 42 are both driven by the first fan 52. When there are multiple first fans 52, the second fan 54 is driven by the first fan 52 closest to the intake pipe 2, and the cleaning block drive shaft 42 is driven by the first fan 52 closest to the exhaust pipe 3. Adjacent first fans 52 are driven by a drive shaft 56.
[0050] The working principle of this utility model is as follows: When the motor 51 is started, the motor 51 drives the two first fans 52 to rotate synchronously. At the same time, the first fan 52 on the left drives the second fan 54 to rotate, and the first fan 52 on the right drives the cleaning block drive shaft 42 to rotate, thereby driving the cleaning block 41 to reciprocate. The air inside the factory enters the main sleeve 1 through the air intake 2 and the two first fans 52. After the dust is filtered out by the filter plate 6, it is discharged from the exhaust pipe 3. The dust left on the front of the filter plate 6 is wiped off by the cleaning block 41 and falls into the collection box 45.
[0051] This utility model has a simple structure and is easy to use. It eliminates the need for manual cleaning and replacement of the filter plates, thus improving the convenience of use and maintenance. Furthermore, the number of first fans can be selected according to usage requirements to meet the ventilation needs of the factory and improve air purification efficiency.
[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
