Description

Technical Field

[0001] This utility model belongs to the field of clean technology and environmental monitoring, and in particular relates to a PSL generator with a movable base. Background Technology

[0002] With the continuous development of clean technology in fields such as semiconductor manufacturing, biomedicine, and precision instruments, the requirements for monitoring and verifying environmental cleanliness are becoming increasingly stringent. As a core device for generating standard particles, PSL generators are widely used in key processes such as HEPA filter leak detection and cleanroom performance evaluation.

[0003] However, traditional PSL generators have many inconveniences in use: First, the equipment is large and heavy, and usually lacks a dedicated moving structure. It requires multiple people to move it, which is not flexible and makes it difficult to meet the testing needs of multiple stations. Second, the equipment needs to be placed on a flat platform when working, but most of the equipment lacks a reliable fixing mechanism. It is easy for it to be displaced or tipped over due to collisions caused by personnel walking, airflow disturbances, or vibrations of the equipment itself. This can cause the aerosol output direction to deviate, affecting the uniformity of particle distribution and the accuracy of test results. In severe cases, it may even cause test failure.

[0004] Therefore, there is a particular need for a PSL generator with a movable base to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of traditional PSL generators, such as being bulky, difficult to move, lacking stable fixation, and easily causing displacement and output deviation during use, this utility model provides a PSL generator with a movable base.

[0006] This utility model is achieved through the following technical means: A PSL generator with a movable base includes a generator body, a pressure regulator, a connecting pipe, an oil inlet, and a smoke outlet. The pressure regulator is installed on the left side of the generator body, the connecting pipe is installed on the upper side of the pressure regulator, the oil inlet is installed on the top of the generator body, and the smoke outlet is installed on the rear of the generator body. It also includes a support base, movable wheels, suction cups, a connecting plate, a servo motor, a lead screw, and a controller. The support base is installed on the lower part of the generator body, and a movable wheel is installed at each of the multiple corners of the lower part of the support base. The servo motor is installed at the bottom of the support base, the lead screw is fixed to the output shaft of the servo motor, the connecting plate is threaded on the outside of the lead screw, and multiple suction cups are installed on it. The suction cups pass through the support base and slide with it. The controller is installed on the front side of the support base and is electrically connected to the servo motor.

[0007] Preferably, a handle is also included, which is mounted on the top of the generator body and located to the right of the oil inlet.

[0008] Preferably, it also includes an accessory box, which is slidably placed inside the front of the support base.

[0009] Preferably, a cushioning pad is also included, which is placed inside the accessory box.

[0010] Preferably, the device also includes a magnet one and a magnet two. Magnet one is fixed to the rear of the accessory box, and magnet two is fixed to the corresponding position inside the support base and is located behind magnet one to attract it.

[0011] As a preferred option, the handle is equipped with an anti-slip sleeve.

[0012] Beneficial effects: 1. The combination of support base and casters enables convenient movement of the equipment, improving the flexibility of operation in multiple workstations. The automatic lifting and fixing mechanism composed of suction cup, connecting plate, servo motor, lead screw and controller can automatically lock the equipment after reaching the detection point to prevent displacement, ensure the stability of the smoke outlet direction and guarantee detection accuracy. At the same time, the height of the equipment can be finely adjusted to adapt to different usage needs.

[0013] 2. By setting up a sliding accessory box and equipping it with a cushioning pad, various accessories required for the generator body can be stored in a centralized manner to avoid loss or damage and improve the integrity of the equipment. The magnetic adsorption structure of magnet one and magnet two realizes reliable positioning and self-locking of the accessory box, ensuring that the accessory box is stable and does not slip out during equipment movement or vibration, thus improving the safety of use.

[0021] Example: A PSL generator with a movable base, such as Figures 1-6 As shown, the device includes a generator body 1, a handle 2, a pressure gauge 3, a connecting pipe 301, an oil inlet 4, and a smoke outlet 5. The handle 2 is bolted to the top of the generator body 1 and is located to the right of the oil inlet 4. The handle 2 is equipped with an anti-slip sleeve. The pressure gauge 3 is bolted to the left side of the generator body 1, and the connecting pipe 301 is bolted to the upper left side of the pressure gauge 3. The oil inlet 4 is bolted to the top of the generator body 1, and the smoke outlet 5 is bolted to the rear of the generator body 1. It also includes a support base 6, casters 7, a suction cup 10, a connecting plate 13, a servo motor 14, and a lead screw 15. The controller 16 and the support base 6 are bolted to the lower part of the generator body 1. Each of the four corners of the lower part of the support base 6 is bolted to a movable wheel 7. The servo motor 14 is bolted to the bottom of the support base 6, and its output shaft extends vertically upward. The lead screw 15 is fixedly connected to the output shaft of the servo motor 14 through a coupling. The connecting plate 13 is threaded on the outside of the lead screw 15, and three suction cups 10 are bolted to it. The suction cups 10 pass through the support base 6 and slide with it. The controller 16 is bolted to the right side of the front part of the support base 6 and is electrically connected to the servo motor 14.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes an accessory box 8, a buffer pad 9, a magnet 11, and a magnet 2 12. The accessory box 8 is slidably placed in the front of the support base 6, the buffer pad 9 is placed inside the accessory box 8, the magnet 11 is fixedly connected to the rear of the accessory box 8, and the magnet 2 12 is fixedly connected to the corresponding position inside the support base 6 and is located behind the magnet 11 to attract it, thereby fixing the accessory box 8 inside the support base 6 and preventing the accessory box 8 from accidentally sliding out.

[0023] In use, the operator can easily push the generator body 1 to the target detection position on the table using the movable wheels 7. After reaching the designated position, the servo motor 14 is started by the controller 16. The output shaft of the servo motor 14 drives the lead screw 15 to rotate clockwise. Under the drive of the lead screw 15, the connecting plate 13 moves downward along the lead screw 15, thereby driving the three suction cups 10 on it to extend downward simultaneously. When the suction cups 10 contact the table, they continue to move downward to generate a pre-tightening force, so that the suction cups 10 are tightly attached to the table to form an adsorption, thereby achieving stable fixation of the equipment. When the suction cups 10 move downward to the appropriate position and appropriately raise the height of the generator body 1, the servo motor 14 is immediately turned off, and the equipment enters the detection working state. After the test is completed, the servo motor 14 is restarted, and its output shaft is controlled to drive the lead screw 15 to rotate counterclockwise, so that the connecting plate 13 moves upward, the three suction cups 10 retract upward, the moving wheel 7 contacts the table again, and the equipment returns to the moving state, making it easy to move. In addition, the accessory box 8 is slidably stored inside the support base 6. When in use, it can be pulled out to hold accessories such as nozzles, connecting pipes 301, and calibration tools. During placement, the buffer pad 9 provides shock absorption and protection to prevent damage to the accessories due to collisions. After use, the accessory box 8 is pushed back to its original position, and magnet 11 and magnet 212 attract each other to achieve automatic locking, preventing the accessory box 8 from accidentally sliding out during equipment movement.
