Description

Technical Field

[0001] This utility model relates to the technical field of clean benches, and in particular to a multifunctional clean bench control module. Background Technology

[0002] Clean benches are widely used in fields such as scientific research, medical care, and electronics where high levels of environmental cleanliness are required. Their main function is to provide a localized, highly clean environment for the operating area to prevent dust, microorganisms, and other contaminants from interfering with experimental and production processes. To ensure air circulation during operation, clean benches use motorized louvers at the fan location in conjunction with a control module to adjust the airflow speed to different degrees. Although existing control modules and motorized louvers can easily control the fan speed, they are generally fixed to the fan using bolts or other fasteners. This makes disassembly and maintenance after a malfunction relatively time-consuming, affecting the efficiency of the clean bench. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multifunctional clean bench control module.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] By utilizing the contact between the frame and the outer wall of the fan, and the fit between the through holes in the frame and the column, the frame can be quickly installed on the fan. Due to the presence of the locking blocks, the frame can be fixed in a certain way. In this way, the disassembly and maintenance of the frame after a failure is relatively time-saving, and the time spent on disassembly and assembly can avoid affecting the efficiency of the clean workbench.

[0006] Preferably, the exposed ends of all the card blocks are designed as hemispherical.

[0007] Preferably, the frame is connected to multiple sets of slide rails, and all sets of slide rails are slidably connected to the rod.

[0008] Preferably, the shape of the frame is adapted to the shape of the contact portion with the fan.

[0009] Preferably, the fan is connected to a base, and the base has connecting grooves at one end and the other end.

[0010] Preferably, each of the multiple sets of baffles has an arc-shaped groove.

[0011] Preferably, there is a certain distance between the two sets of baffles.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By cooperating with the fan, column, frame, through holes, springs and clips, the frame can be quickly installed on the fan by the contact between the frame and the outer wall of the fan and the fit between the through holes of the frame and the column. The clips can also restrict and fix the frame. This makes the disassembly and maintenance of the frame relatively time-saving after a failure, and can avoid the time-consuming disassembly and assembly that affects the efficiency of the clean bench.

[0014] 2. Through the coordination of the motor, screw, rod, slider, baffle, through slot, wireless reversing switch, and slide rail, the forward and reverse rotation of the motor driven by the wireless reversing switch can drive the screw to move the rod and adjust the slider's position. In this way, the slider can synchronously rotate the two sets of baffles in opposite directions through the connection with the through slot, so as to block one end of the fan to different degrees. This can adjust the airflow of the fan. At the same time, the two sets of baffles can also completely block one end of the fan, protecting the fan when it is not in operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A multifunctional clean bench control module includes a fan 1, the model of which is selected according to actual work requirements. Multiple sets of columns 2 are connected to the fan 1, and the connection between the fan 1 and the multiple sets of columns 2 adopts an integrated welding process to ensure a firm and reliable connection. The columns 2 are evenly distributed at specific positions on the outer shell of the fan 1, and their shape is cylindrical. A frame 3 is attached to the fan 1, and multiple sets of through holes 4 are opened in the frame 3, which movably pass through the corresponding columns 2. Springs 5 ​​and locking blocks 6 are placed in the cavities of each set of columns 2. One end of each set of springs 5 ​​is connected to the corresponding column 2 and locking block 6, respectively. Each set of locking blocks 6 is in contact with the frame 3. A motor 7 is installed on the frame 3. The motor 7 is a high-precision, low-noise DC brushless motor, which has the advantages of stable speed, wide speed range, and long life. The model is selected according to actual work requirements. A wireless forward / reverse switch 8 is installed on the motor 7. The wireless reversing switch 8 adopts advanced Bluetooth wireless control technology, which has reliable signal transmission and strong anti-interference ability. Operators can conveniently control the forward and reverse rotation of the motor 7 through a remote control or mobile APP to achieve remote and precise adjustment of the opening and closing angle of the baffle 12. This is existing technology and will not be described in detail here. The model is selected according to the actual work requirements. The output end of the motor 7 is connected to a screw 9, and the screw 9 is threaded to a rod 10. The rod 10 is threaded to multiple sets of sliders 11, which can be easily replaced. Multiple sets of baffles 12 are rotatably connected to the frame 3. Each set of baffles 12 has a through groove 13, which is movably connected to the corresponding slider 11. By moving the locking block 6 into the inner cavity of the column 2, the fixing of the frame 3 can be removed. In this way, the frame 3 can be quickly disassembled and assembled, which saves time during maintenance and avoids the time spent on disassembly and assembly from affecting the efficiency of the clean workbench.

[0023] In this embodiment, the exposed ends of multiple sets of locking blocks 6 are all hemispherical, which not only facilitates the installation and disassembly of the frame 3 and reduces the friction between the locking blocks 6 and the frame 3, but also, to a certain extent, avoids damage to the locking blocks 6 or injury to personnel due to collisions. Multiple sets of slide rails 14 are connected to the frame 3, and all sets of slide rails 14 are slidably connected to the rod 10. The shape of the contact portion between the frame 3 and the fan 1 is adapted to the shape of the fan 1. The shape of the contact portion between the frame 3 and the fan 1 is designed as a curved surface that perfectly matches the curvature of the fan 1's outer casing. This shape adaptation design... The design allows the frame 3 to fit tightly against the fan 1, increasing the contact area. A base 16 is connected to the fan 1. One end of the base 16 and the other end are provided with connecting grooves 17. The connecting grooves 17 are used to cooperate with external connecting parts to install the base 16 on the clean workbench. Multiple sets of baffles 12 are provided with arc-shaped grooves 15. The arc-shaped grooves 15 are used to accommodate the column 2 when the baffle 12 rotates, avoiding collision between the baffle 12 and the column 2. There is a certain distance between the two sets of baffles 12 to avoid mutual wear when the two sets of baffles 12 rotate.

[0024] The working principle of this embodiment is as follows: In use, the wireless reversing switch 8 drives the motor 7 to run. The motor 7 drives the screw 9 to rotate in both directions, which can adjust the lifting position of the rod 10. As the rod 10 moves synchronously with the slider 11, the slider 11 and the through groove 13 cooperate to rotate the two sets of baffles 12 synchronously in opposite directions. The two sets of baffles 12 will open and close to block the fan 1 to different degrees, thereby controlling the airflow. When disassembly is required, the frame 3 is pushed along the orientation of the column 2. The frame 3 will contact the semi-circular part of the locking block 6, and then the locking block 6 will be pressed into the cavity of the column 2. The frame 3 is then disassembled from the fan 1. The disassembly and assembly are convenient and time-saving.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
