Description

Technical Field

[0001] This utility model relates to the technical field of fresh air purification devices, specifically a fresh air purification device for a cleanroom. Background Technology

[0002] A cleanroom, also known as a clean workshop, clean room, or clean factory, is a special room that uses technology to remove airborne particles, harmful gases, bacteria, and other pollutants from a specific space, and to control parameters such as temperature, humidity, cleanliness, and airflow speed within a specific range. It is widely used in many fields such as microelectronics, pharmaceuticals, food, and precision machinery to ensure the cleanliness of the production environment and product quality. Traditional cleanroom fresh air purification devices are mostly fixed installations, with relatively simple air supply positions that cannot be flexibly adjusted, resulting in poor air supply effect. To improve this situation, a cleanroom fresh air purification device is proposed.

[0003] For example, the cleanroom fresh air purification device disclosed in the authorization announcement number CN222352467U includes an air supply duct, an air inlet on one side of the air supply duct, a first barrier screen on one side of the air supply duct, the first barrier screen being snapped onto the outer end of the air inlet, a filter screen being fixedly connected inside the air inlet, and a cleaning component being provided at the outer end of the air supply duct. The cleaning component includes a support shaft rotatably connected inside the air supply duct, the support shaft being disposed between the first barrier screen and the filter screen, and a rotating plate being fixedly connected to the outer end of the support shaft.

[0004] Although it achieves the cleaning of dust and lint adhering to the inner side of the first barrier screen and the outer side of the filter screen by the bristles at the outer end of the rotating plate, it prevents a large amount of dust and lint from clogging the first barrier screen and the filter screen after long-term use of the purification device, thereby affecting the air intake efficiency of the air supply duct.

[0005] However, this does not solve the problem that existing fresh air purification devices are not conducive to convenient and flexible adjustment of the air outlet duct position during use, and are not conducive to supplying air to different locations inside the cleanroom, thus affecting the flexibility of air supply. Utility Model Content

[0006] The purpose of this utility model is to provide a fresh air purification device for cleanrooms, so as to solve the problem mentioned in the background art that the fresh air purification device is not convenient and flexible in adjusting the position of the air outlet duct, which is not conducive to supplying air to different positions inside the cleanroom and affects the flexibility of air supply.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleanroom fresh air purification device, comprising an integrated frame and a bidirectional lead screw. The integrated frame contains a bidirectional lead screw, which is movably connected to the integrated frame. A servo motor is mounted on the side wall of the integrated frame, and the output end of the servo motor is connected to the bidirectional lead screw. Two sets of threaded sleeves are fitted on the surface of the bidirectional lead screw, and the threaded sleeves are threadedly connected to the bidirectional lead screw and slidably connected to the integrated frame. A placement plate is mounted on the side wall of each threaded sleeve, and an air outlet pipe is mounted inside each placement plate. A flexible hose is mounted at one end of each air outlet pipe, and the flexible hose is connected to the fresh air system's air supply duct. A walking frame is provided on the outside of the integrated frame.

[0008] Preferably, two sets of walking tracks are provided above the walking frame, and two sets of electric wheels are symmetrically installed at the top of the walking frame, with the electric wheels slidably connected to the walking tracks.

[0009] Preferably, the walking frame is provided with a placement seat inside, and a support arm is provided at the center of the placement seat, and the support arm is movably connected to the placement seat.

[0010] Preferably, a toothed ring is installed at the top of the bearing arm, and the toothed ring is slidably connected to the placement seat.

[0011] Preferably, a drive motor is installed at the bottom of the placement base, and a gear is installed at the output end of the drive motor, with the gear meshing with a gear ring.

[0012] Preferably, the bottom end of the support arm is provided with an adjusting arm, and the side of the adjusting arm near the support arm is provided with a linkage shaft, and the adjusting arm is movably connected to the support arm through the linkage shaft.

[0013] Preferably, an electric push rod is movably mounted on the side wall of the bearing arm, and a push arm is mounted on the output end of the electric push rod.

[0014] Preferably, the push arm is provided with a hinge shaft at one end near the adjusting arm, and the push arm is movably connected to the adjusting arm through the hinge shaft, and the adjusting arm is connected to the integrated frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the fresh air purification device not only realizes the convenient and flexible adjustment of the position of the air outlet duct, which facilitates the supply of air to different positions inside the cleanroom, but also improves the flexibility of air supply.

[0016] The flexible hose is connected to the fresh air system's air supply duct. The fresh air system delivers purified air into the flexible hose and sprays it out from the air outlet duct to complete the air supply operation in the cleanroom. When it is necessary to adjust the distance between the two sets of air outlet ducts to make the air supply more uniform, the servo motor drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two sets of threaded sleeves to move in opposite directions. The threaded sleeves drive the placement plate and the air outlet duct to move away from each other, thereby adjusting the distance between the two sets of air outlet ducts to make the supplied air more uniform. When it is necessary to moderately rotate and adjust the air supply position of the air outlet duct, the drive motor drives the gear to rotate. The gear drives the bearing arm to rotate through the gear ring. The bearing arm drives the adjusting arm, the integrated frame and the air outlet duct to rotate moderately, thereby moderately rotating and adjusting the air supply position of the air outlet duct to flexibly supply air. This realizes convenient and flexible adjustment of the position of the air outlet duct, which facilitates air supply to the cleanroom from different positions and improves the flexibility of air supply.

[0017] The push arm is moved by an electric push rod, and the push arm drives the adjusting arm to rotate around the linkage shaft via a hinge shaft. The adjusting arm drives the integrated frame and the air outlet duct to rotate, thereby adjusting the height of the air outlet duct to facilitate air delivery from different heights. At the same time, by controlling the electric wheels, the electric wheels drive the traveling frame to move on the traveling track surface. The traveling frame drives the placement seat, the support arm, the adjusting arm, the integrated frame, and the air outlet duct to move and adjust the air delivery position of the air outlet duct, so as to facilitate air delivery to different locations inside the cleanroom and thus improve the air delivery effect.

[0025] Please see Figure 1-5 An embodiment of this utility model provides a cleanroom fresh air purification device, including an integrated frame 6 and a bidirectional lead screw 19. The bidirectional lead screw 19 is provided inside the integrated frame 6 and is movably connected to the integrated frame 6. A servo motor 20 is installed on the side wall of the integrated frame 6, which serves as a power drive and its output end is connected to the bidirectional lead screw 19. Two sets of threaded sleeves 8 are fitted on the surface of the bidirectional lead screw 19 and are threadedly connected to the bidirectional lead screw 19. The threaded sleeves 8 are also slidably connected to the integrated frame 6. A placement plate 9 is installed on the side wall of each threaded sleeve 8, and an air outlet pipe 10 is installed inside each placement plate 9. A flexible hose 7 is installed at one end of each air outlet pipe 10 and is connected to the fresh air system supply pipe. A walking frame 2 is provided outside the integrated frame 6.

[0026] The flexible hose 7 is connected to the fresh air system's supply duct. The fresh air system delivers purified air into the flexible hose 7 and exits through the outlet duct 10 to supply air to the cleanroom. When it is necessary to adjust the distance between the two sets of outlet ducts 10 to make the air supply more uniform, the servo motor 20 is turned on. The servo motor 20 drives the bidirectional lead screw 19 to rotate. With the threaded connection between the bidirectional lead screw 19 and the threaded sleeve 8, and the sliding engagement between the threaded sleeve 8 and the integrated frame 6, the bidirectional lead screw 19 drives the two sets of threaded sleeves 8 to move in opposite directions. The threaded sleeves 8 drive the placement plate 9 and the outlet duct 10 to move away from each other, thereby adjusting the distance between the two sets of outlet ducts 10 to make the air supply more uniform. The supplied air is more uniform. When it is necessary to adjust the air supply position of the air outlet duct 10, the drive motor 18 is turned on. The drive motor 18 drives the gear 17 to rotate. Under the mutual meshing of the gear 17 and the gear ring 16, and the movable cooperation between the support arm 11 and the placement seat 4, the gear 17 drives the support arm 11 to rotate through the gear ring 16. The support arm 11 drives the adjustment arm 5, the integrated frame 6 and the air outlet duct 10 to rotate appropriately, thereby adjusting the air supply position of the air outlet duct 10 to flexibly supply air. This realizes the convenient and flexible adjustment of the position of the air outlet duct, which facilitates the supply of air to the cleanroom from different positions and improves the flexibility of air supply.

[0027] Two sets of walking tracks 1 are set above the walking frame 2. Two sets of electric wheels 3 are symmetrically installed at the top of the walking frame 2. The electric wheels 3 play a power driving role and are slidably connected to the walking track 1.

[0028] The walking frame 2 is provided with a placement seat 4 inside. A support arm 11 is provided at the center of the placement seat 4 and is movably connected to the placement seat 4.

A linkage shaft 12 is provided on the side of the adjustment arm 5 near the support arm 11, and the adjustment arm 5 is movably connected to the support arm 11 through the linkage shaft 12.

[0030] An electric push rod 13 is movably mounted on the side wall of the bearing arm 11. The electric push rod 13 serves as a power drive. A push arm 14 is mounted on the output end of the electric push rod 13. A hinge shaft 15 is provided at one end of the push arm 14 near the adjusting arm 5. The push arm 14 is movably connected to the adjusting arm 5 through the hinge shaft 15. The adjusting arm 5 is connected to the integrated frame 6.

[0031] Open the electric push rod 13, which drives the push arm 14 to move. The push arm 14 drives the adjusting arm 5 to rotate around the linkage shaft 12 via the hinge shaft 15. The adjusting arm 5 drives the integrated frame 6 and the air outlet duct 10 to rotate, thereby adjusting the height of the air outlet duct 10 to facilitate air delivery from different heights. At the same time, by controlling the electric wheel 3, the electric wheel 3 drives the traveling frame 2 to move on the surface of the traveling track 1. The traveling frame 2 drives the placement seat 4, the bearing arm 11, the adjusting arm 5, the integrated frame 6, and the air outlet duct 10 to move and adjust the air delivery position of the air outlet duct 10, thereby facilitating air delivery to different locations inside the cleanroom and improving the air delivery effect.

[0032] Working Principle: The flexible hose 7 is connected to the fresh air system's air supply duct. The fresh air system delivers purified air into the flexible hose 7 and sprays it out from the air outlet duct 10 to complete the air supply operation in the cleanroom. When it is necessary to adjust the distance between the two sets of air outlet ducts 10 to make the air supply more uniform, the servo motor 20 drives the bidirectional lead screw 19 to rotate. The bidirectional lead screw 19 drives the two sets of threaded sleeves 8 to move in opposite directions. The threaded sleeves 8 drive the placement plate 9 and the air outlet duct 10 to move away from each other, thereby adjusting the distance between the two sets of air outlet ducts 10 to make the supplied air more uniform. When it is necessary to moderately rotate and adjust the air supply position of the air outlet duct 10, the drive motor 18 drives the gear 17 to rotate. With the movable cooperation between the support arm 11 and the placement seat 4, the gear 17 drives the support arm 11 to rotate through the gear ring 16. The support arm 11 drives the adjustment... The entire arm 5, integrated frame 6, and air outlet duct 10 are rotated moderately to adjust the air supply position of the air outlet duct 10 for flexible air supply. The electric push rod 13 drives the push arm 14 to move, and the push arm 14 drives the adjusting arm 5 to rotate around the linkage shaft 12 via the hinge shaft 15. The adjusting arm 5 drives the integrated frame 6 and air outlet duct 10 to rotate, thereby adjusting the height of the air outlet duct 10 to facilitate air supply from different heights. At the same time, by controlling the electric wheel 3, the electric wheel 3 drives the traveling frame 2 to move on the surface of the traveling track 1. The traveling frame 2 drives the placement seat 4, bearing arm 11, adjusting arm 5, integrated frame 6, and air outlet duct 10 to move and adjust the air supply position of the air outlet duct 10 to facilitate air supply to different locations inside the cleanroom. The above is the complete usage of the cleanroom fresh air purification device.
