[0014] In the following description, embodiments of the lifting structure of the oil mist purifier of this utility model will be described with reference to the accompanying drawings.

[0015] Figure 1-4 This invention illustrates a hinged top structure for an oil mist purifier according to an embodiment of the present invention. It includes an upper cover plate 2 at the top of the oil mist purifier 1. Two symmetrical L-shaped support seats 10 are fixedly installed at the bottom of the oil mist purifier 1. The L-shaped support seats 10 allow for easy bolt fixation of the oil mist purifier 1 onto a machine tool. Fixing strips 1-3 are fixedly connected to the right ends of the front and rear sides of the oil mist purifier 1. Long grooves 4 are provided on the fixing strips 1-3. Movable pins 5, which move within the long grooves 4, are fixedly connected to the right ends of the front and rear sides of the inner cavity of the upper cover plate 2. Fixing strips 2-6 are fixedly connected to the left ends of the front and rear sides of the oil mist purifier 1. L-shaped grooves 7 are provided on the fixing strips 2-6. Sliding pins 8, which slide within the L-shaped grooves 7, are fixedly connected to the left ends of the front and rear sides of the inner cavity of the upper cover plate 2. A section is provided between the top left side of the upper cover plate 2 and the oil mist purifier 1. The device includes a locking and tightening assembly 9, which includes an L-shaped block 91 fixedly connected to the top left side of the upper cover plate 2. The top of the L-shaped block 91 has a U-shaped cavity 92. A fixing seat 93 is fixedly connected to the top left side of the oil mist purification device 1. A threaded sleeve 94 is rotatably connected to the inner cavity of the fixing seat 93 via a rotating shaft. A threaded rod 95 is threadedly connected to the inner cavity of the threaded sleeve 94. The end of the threaded rod 95 passes through the U-shaped cavity 92 and is provided with a limiting block 96 sleeved on the surface of the threaded rod 95. The limiting block 96 is rotatably connected to the threaded rod 95 and abuts against the inner side of the L-shaped block 91. A handwheel 97 is fixedly installed at the end of the threaded rod 95 away from the limiting block 96. By setting the L-shaped block 91, the L-shaped block 91 can limit the limiting block 96, effectively preventing the limiting block 96 from disengaging from the inner side of the L-shaped block 91, thus ensuring the stability of the upper cover plate 2 in a fixed state.

[0016] Working principle: When using this utility model, if it is necessary to open the upper cover plate 2, the handwheel 97 is rotated. Due to the threaded sleeve 94, the threaded rod 95 moves to the right and rotates. The threaded rod 95 then drives the limiting block 96 to move, causing the limiting block 96 to move out of the inner cavity of the L-shaped block 91. Then, the handwheel 97 is pressed down, causing the threaded sleeve 94, the threaded rod 95, and the limiting block 96 to rotate, causing the threaded rod 95 and the limiting block 96 to disengage from the inner cavity of the U-shaped cavity 92. Then, the upper cover plate 2 is pushed to the right, and the upper cover plate 2 drives the sliding pin 8 and the movable pin 5. Moving to the right, the sliding pin 8 moves to the corner within the L-shaped groove 7 on the second fixed strip 6, while the movable pin 5 moves to the end within the long groove 4 on the first fixed strip 3. Then, the left side of the upper cover plate 2 is lifted upwards, and the sliding pin 8 on the upper cover plate 2 disengages from the inner cavity of the L-shaped groove 7. The movable pin 5 on the upper cover plate 2 rotates within the inner cavity of the long groove 4, causing the upper cover plate 2 to be in the open state. A sealing gasket is provided on the inner side of the upper cover plate 2, which ensures a sealing effect between the upper cover plate 2 and the oil mist purification device 1 when pressed against the top of the oil mist purification device 1.

[0017] In summary: This oil mist purifier's hinged top structure, through the operation of the locking and tightening assembly 9, separates the limiting block 96 from the L-shaped block 91. Then, the upper cover 2 is pushed to the right, causing the sliding pin 8 to slide within the L-shaped groove 7 to the corner. The movable pin 5 then slides within the long groove 4 to the right end. Next, the upper cover 2 is lifted upwards, and the sliding pin 8 on the inner side of the upper cover 2 disengages from the inner cavity of the L-shaped groove 7. The movable pin 5 within the upper cover 2 rotates within the long groove 4, causing the upper cover 2 to be in the hinged state. This achieves the goal of opening the top cover using a hinged method, facilitating the operator's inspection, cleaning, and replacement of internal components such as the filter and fan, thus reducing maintenance time.
