When the bayonet is aligned with the slot, the bayonet is not squeezed. Under the action of the elasticity of the second spring, the bayonet is pushed into the slot for locking. At this time, the filter frame and the filter membrane are quickly installed. When the filter frame and the filter membrane need to be replaced, the operator holds the top surface of the filter frame to fix it. The installed handle presses the pull frame with the palm of the hand to make the inclined surface of the pull frame end contact and squeeze with the inclined surface of the latch, so that the latch slides to the inside of the limit groove and no longer engages with the latch groove. At this time, the pull frame covers the latch groove, and the handle is pulled to lift the filter frame and the filter membrane to replace them. During installation, the filter frame and the filter membrane can be inserted into the filter box. Under the action of the first spring elasticity, the pull frame is pushed upward so that the pull frame and the latch are no longer in contact, so that the filter frame and the filter membrane can be stably installed. This structure allows the filter frame and the filter membrane to be replaced with one hand, and no external tools are required, making it more convenient for the operator to replace the filter membrane.

[0016] 2. The filtering device, which is convenient for replacing the contaminated filter membrane, is composed of a sealing component as one of its components. When the filter frame and the filter membrane are installed inside the filter box, the sealing strip is squeezed so that the sealing strip drives the slider fixedly installed at the end of the second magnetic strip to slide inside the slide groove opened on the inner wall of the filter box. Under the restriction of the mutual magnetic repulsion between the first magnetic strip and the second magnetic strip, the sealing strip is pushed toward the filter frame and the filter membrane. Under the restriction of the sealing strip, the gap between the filter frame and the baffle frame can be filled to ensure the overall sealing of the filter box and achieve a better filtering effect.

[0029] A filter frame 4 is slidably arranged inside the filter box 1;

[0030] A filter membrane 5 is fixedly installed inside the filter frame 4;

[0031] And a processing component 6 arranged inside the filter box 1, the processing component 6 includes a replacement component 61 arranged inside the filter box 1, the replacement component 61 includes a slide rod 611 fixedly installed on the outer wall of the filter frame 4, the outer wall of the slide rod 611 is sleeved with a first spring 612, the outer wall of the slide rod 611 is slidably provided with a pull frame 613, the side wall of the filter frame 4 is provided with a frame groove 614, the inner wall of the frame groove 614 is provided with a card groove 615, the inner wall of the filter box 1 is provided with a limiting groove 616, the limiting groove 616 is provided with a second spring 617, the end of the second spring 617 is fixedly installed with a limiting plate 618, and the end of the limiting plate 618 away from the second spring 617 is fixedly installed with a bayonet 619.

[0032] In this embodiment, when it is necessary to install the filter frame 4 and the filter membrane 5, they are inserted into the filter box 1. When the bottom of the filter frame 4 contacts and squeezes the inclined surface of the bayonet 619, the bayonet 619 drives the limiting plate 618 to slide into the limiting groove 616 and compresses the second spring 617. When the bayonet 619 is aligned with the slot 615, the bayonet 619 is not squeezed. Under the elastic action of the second spring 617, the bayonet 619 is pushed into the slot 615 for locking. At this time, the filter frame 4 and the filter membrane 5 are quickly installed. When it is necessary to replace the filter frame 4 and the filter membrane 5, the operator holds the handle fixed on the top surface of the filter frame 4 and presses the pull frame 613 with the palm of his hand. The inclined surface at the end of the pull frame 613 is contacted and squeezed with the inclined surface of the latch 619, so that the latch 619 slides into the limiting groove 616 and is no longer engaged with the latch slot 615. At this time, the pull frame 613 covers the latch slot 615, and the handle is pulled to lift the filter frame 4 and the filter membrane 5 to replace them. During installation, the filter frame 4 and the filter membrane 5 can be inserted into the filter box 1. Under the elastic action of the first spring 612, the pull frame 613 is pushed upward so that the pull frame 613 and the latch 619 are no longer in contact, so that the filter frame 4 and the filter membrane 5 can be stably installed. This structure allows the filter frame 4 and the filter membrane 5 to be replaced by one hand without the need for external tools, making it more convenient for the operator to replace the filter membrane 5.

[0033] Among them, the end of the pull frame 613 is set at an inclined surface, and the end of the pin 619 away from the limiting plate 618 is set at an inclined surface. Under its restriction, when the pull frame 613 moves downward, it can be squeezed with the inclined surface of the pin 619, so that the pin 619 and the slot 615 are no longer engaged, so as to remove the filter frame 4 and the filter membrane 5 from the inside of the filter box 1.

[0034] Among them, one end of the second spring 617 is fixedly installed on the inner wall of the limiting groove 616, and the end of the second spring 617 away from the inner wall of the limiting groove 616 is fixedly installed on the side of the limiting plate 618 away from the pin 619. Under the elastic restriction of the second spring 617, when the pin 619 is not squeezed, it can be engaged with the slot 615, so that the filter frame 4 and the filter membrane 5 are stably installed inside the filter box 1.

[0035] Among them, the outer wall of the limit plate 618 is slidably arranged with the inner wall of the limit groove 616, and the end of the pull frame 613 is slidably arranged with the inner wall of the frame groove 614. Under its restriction, when the pull frame 613 slides downward, the inclined surface of the pin 619 is squeezed. Under the restriction of the sliding of the limit plate 618 and the limit groove 616, the pin 619 can stably slide into the inside of the limit groove 616.

[0038] In this embodiment, when the filter frame 4 and the filter membrane 5 are installed inside the filter box 1, they squeeze the sealing strip 626, so that the sealing strip 626 drives the slider 624 fixedly installed at the end of the second magnetic strip 625 to slide inside the slide groove 623 opened on the inner wall of the filter box 1. Under the restriction of the mutual magnetic repulsion between the first magnetic strip 622 and the second magnetic strip 625, the sealing strip 626 is pushed toward the filter frame 4 and the filter membrane 5. Under the restriction of the sealing strip 626, the gap between the filter frame 4 and the baffle frame 621 can be filled to ensure the overall sealing of the filter box 1 and achieve a better filtering effect.

[0039] The outer wall of the sealing strip 626 is slidably arranged inside the baffle frame 621 . The sealing strip 626 is made of rubber sealing material. Under its restriction, the gap between the baffle frame 621 and the filter frame 4 can be sealed and filled to improve the overall filtering effect of the filter box 1 .

[0040] Among them, the second magnetic strip 625 and the first magnetic strip 622 magnetically repel each other, and the slider 624 fixedly installed at the end of the second magnetic strip 625 is slidably arranged in the slide groove 623 opened on the inner wall of the filter box 1.
