After the replacement is completed, the ventilation plate is slid upward by the pull rod so that the movable disk contacts the limit block.

[0017] The present invention cooperates with structures such as a transmission rod, a transmission fan, and a first bevel gear so that when the device is inhaling, air enters the device through the right vent and contacts the transmission fan, so that the transmission fan contacts the wind through its own shape and drives itself to rotate, thereby driving the transmission rod to rotate, so that the transmission rod drives the first bevel gear to rotate, and then the first bevel gear drives the second bevel gear and the reciprocating screw to rotate. Since the outer wall of the reciprocating screw is provided with a reciprocating thread, the reciprocating screw can drive the cleaning plate to reciprocate through its own shape when rotating, and the cleaning plate can clean the filter when moving to prevent the filter from being blocked and affecting the efficiency of air intake, thereby achieving the purpose of facilitating the cleaning of the filter and preventing it from being blocked.

[0018] The present invention cooperates with structures such as noise reduction grooves, sound delay blocks, and sound absorbing blocks so that when wind enters the interior of the device and generates wind noise by passing between various components, the device can extend the path of sound propagation by opening a noise reduction groove on the inner wall of the cabinet and separating it with sound delay blocks, and filter the sound through the sound absorbing blocks and the sound absorbing cotton filled between the sound delay blocks inside the noise reduction groove. The surface of the sound absorbing cotton has a porous structure, and these pores can allow sound waves to enter the interior of the sound absorbing cotton and reflect multiple times therein, thereby increasing the contact area between the sound waves and the sound absorbing cotton material and improving the absorption effect of the sound waves, so as to achieve the purpose of reducing the wind noise generated by the wind passing between the components when the device is in use.

The outer wall of the fan blade 17 is provided with several groups of evenly spaced fan blades, and a noise reduction mechanism 18 is installed on the inner wall of the cabinet 1.

[0025] The above scheme is adopted: the magnetic force of the permanent magnet coil 15 is controlled to control the magnetic suspension rotor 16 to make it rotate, and then the rotation of the magnetic suspension rotor 16 drives the fan blades 17 to rotate, thereby generating suction and transporting it through the air inlet pipe 11, the delivery pipe 12 and the delivery head 13, so that it enters the sewage pool for aeration treatment. During aeration, the wind passing through the ventilation plate 501 and the filter element passes between the mounting frame 8 and the battery 9, cools the battery 9 and other control components inside the device, and improves the service life of the device. This part of the components is the existing technology in this field.

[0026] like Figures 1 to 10 As shown, the quick-release mechanism 5 includes a ventilation plate 501, a mounting groove 502 and a pull rod 503. The ventilation plate 501 is slidably connected to the side wall of the cabinet 1. The inner wall of the cabinet 1 is provided with a mounting groove 502. The outer wall of the ventilation plate 501 is fixed with a pull rod 503. The top of the ventilation plate 501 is fixed with a mounting seat 504. The top of the mounting seat 504 is fixed with a limiting column 505. The top of the limiting column 505 is fixed with a limiting disk 506.

Four groups of mounting seats 504 are provided, and the mounting seats 504 are evenly spaced about the central axis of the ventilation plate 501. The outer wall of the limiting column 505 is close to the inner wall of the movable disk 507, and the limiting column 505 and the movable disk 507 are slidably connected.

[0027] like Figures 1 to 10As shown, a limiting groove 508 is provided at the top of the cabinet 1, and the inner wall of the cabinet 1 is slidably connected to a limiting rod 509. A reset spring 510 is provided on the outer wall of the limiting rod 509, and a limiting block 511 is fixed to the side wall of the limiting rod 509. The limiting rod 509 is provided with two groups of symmetrically distributed about the central axis of the limiting groove 508. The reset spring 510 is used to squeeze the limiting rod 509 and the limiting block 511 and keep them moving toward the central axis of the limiting groove 508. The diameter of the movable disk 507 is larger than the diameter of the limiting disk 506.

[0028] The above scheme is adopted: the ventilation plate 501 is slid upward by the pull rod 503, so that the position of the limit plate 506 moves to the horizontal position of the limit block 511, and then it moves upward, contacts the limit block 511 through its own shape, and squeezes the limit block 511, causing it to shrink and allow the limit plate 506 to pass. After the limit plate 506 passes, the limit block 511 is no longer subject to resistance, and the reset spring 510 resets the limit block 511, causing it to fall to the bottom of the limit plate 506 and limit the limit plate 506, thereby limiting the ventilation plate 501, and temporarily hanging the ventilation plate 501 on the top of the cabinet 1, at this time, the card is installed. The filter element inside the slot 502 is removed and replaced. After the replacement is completed, the ventilation plate 501 is slid upward by the pull rod 503, so that the movable disk 507 contacts the limit block 511, and the limit block 511 contracts to allow the movable disk 507 to pass through, and the movable disk 507 is lifted to contact the limit disk 506. Since the diameter of the contact surface of the movable disk 507 is larger than the limit disk 506, it can be ensured that the limit block 511 will not be stuck between the limit disk 506 and the movable disk 507 when descending. After the ventilation plate 501 is disconnected from the limit slot 508, the ventilation plate 501 is reset downward to protect the filter element from air intake.

[0029] like Figures 1 to 10 As shown, the cleaning mechanism 7 includes a transmission rod 701, a transmission fan 702 and a first bevel gear 703. The transmission rod 701 is rotatably connected to the inner wall of the cabinet 1, the transmission fan 702 is fixed to the side wall of the transmission rod 701, the first bevel gear 703 is fixed to the side wall of the transmission rod 701, the bottom end of the first bevel gear 703 is meshingly connected to the second bevel gear 704, the inner wall of the second bevel gear 704 is fixed with a reciprocating screw 705, the outer wall of the reciprocating screw 705 is threadedly connected to a cleaning plate 706, the outer wall of the transmission fan 702 is provided with a plurality of groups of fan blades, and the fan blades are evenly spaced about the central axis of the transmission fan 702, the reciprocating screw 705 is rotatably connected to the bottom end inside the cabinet 1, and the outer wall of the cleaning plate 706 is provided with a plurality of groups of bristles, and the bristles are arranged at equal intervals.

[0030] The above scheme is adopted: air enters the inside of the device through the right vent 6 and contacts the transmission fan 702, so that the transmission fan 702 contacts the wind through its own shape and drives itself to rotate, and then drives the transmission rod 701 to rotate, so that the transmission rod 701 drives the first bevel gear 703 to rotate, and then the first bevel gear 703 drives the second bevel gear 704 and the reciprocating screw 705 to rotate. Since the outer wall of the reciprocating screw 705 is provided with a reciprocating thread, the reciprocating screw 705 can drive the cleaning plate 706 to reciprocate through its own shape when rotating, and the cleaning plate 706 can clean the filter when moving to prevent the filter from being blocked and affecting the efficiency of air intake.

[0031] like Figures 1 to 10 As shown, the noise reduction mechanism 18 includes a noise reduction groove 1801, a sound-delay block 1802 and a sound-absorbing block 1803. The noise reduction groove 1801 is opened on the inner wall of the cabinet 1, and the sound-delay block 1802 is fixed to the inner wall of the noise reduction groove 1801. The sound-delay block 1802 is fixed to the inner wall of the sound-delay block 1802. The sound-absorbing block 1803 is fixed to the inner wall of the sound-delay block 1802. Several groups of the sound-delay blocks 1802 are evenly spaced about the central axis of the noise reduction groove 1801, and the interior of the noise reduction groove 1801 is filled with sound-absorbing cotton.

[0032] The above scheme is adopted: by opening a noise reduction groove 1801 on the inner wall of the cabinet 1 and separating it with a sound delay block 1802, the sound propagation path is extended, and the sound is filtered by the sound absorbing block 1803 and the sound absorbing cotton filled between the sound delay blocks 1802 inside the noise reduction groove 1801. The surface of the sound absorbing cotton has a porous structure. These pores allow sound waves to enter the interior of the sound absorbing cotton and reflect multiple times therein, thereby increasing the contact area between the sound waves and the sound absorbing cotton material and improving the absorption effect of the sound waves.

[0033] The working principle and use process of the present invention are as follows: the magnetic force of the permanent magnet coil 15 is controlled to control the magnetic suspension rotor 16 to make it rotate, and then the rotation of the magnetic suspension rotor 16 drives the fan blades 17 to rotate, thereby generating suction and conveying it through the air inlet pipe 11, the conveying pipe 12 and the conveying head 13, so that it enters the sewage pool for aeration treatment. During aeration, the wind passing through the ventilation plate 501 and the filter element passes between the mounting frame 8 and the battery 9, cools the battery 9 and other control components inside the device, and improves the service life of the device. This part of the assembly is the existing technology in this field. The ventilation plate 501 is slid upward by the pull rod 503, so that the position of the limit plate 506 moves to the horizontal position of the limit block 511. When the filter element 501 is in the state of being set, it moves upward, contacts the limit block 511 with its own shape, and squeezes the limit block 511, causing it to shrink so that the limit plate 506 passes through. After the limit plate 506 passes through, the limit block 511 is no longer subject to resistance, and the reset spring 510 resets the limit block 511, causing it to fall to the bottom of the limit plate 506 and limit the limit plate 506, thereby limiting the ventilation plate 501, and temporarily hanging the ventilation plate 501 on the top of the cabinet 1. At this time, the filter element stuck in the installation groove 502 is removed and replaced. After the replacement is completed, the ventilation plate 501 is slid upward by the pull rod 503, so that the movable plate 507 contacts the limit block 511, and the limit block 511 shrinks to allow the movable plate 507 to pass through, and lifts the movable plate 507. The movable disk 507 contacts the limit plate 506. Since the diameter of the contact surface of the movable disk 507 is larger than the limit plate 506, it can be ensured that the limit block 511 will not be stuck between the limit plate 506 and the movable disk 507 when descending. After the ventilation plate 501 is disconnected from the limit groove 508, the ventilation plate 501 is reset downward to protect the filter element from air intake. The air enters the device through the right vent 6 and contacts the transmission fan 702, so that the transmission fan 702 contacts the wind through its own shape and drives itself to rotate, thereby driving the transmission rod 701 to rotate, so that the transmission rod 701 drives the first bevel gear 703 to rotate, and then the first bevel gear 703 drives the second bevel gear 704 and the reciprocating screw 705 to rotate. The outer wall is provided with a reciprocating thread so that the reciprocating screw 705 can drive the cleaning plate 706 to reciprocate through its own shape when rotating. The cleaning plate 706 can clean the filter when moving to prevent the filter from being blocked and affecting the efficiency of air intake. A noise reduction groove 1801 is opened on the inner wall of the cabinet 1 and separated by a delay block 1802, thereby extending the path of sound propagation, and filtering the sound through the sound-absorbing block 1803 and the sound-absorbing cotton filled in the noise reduction groove 1801 and between the delay blocks 1802. The surface of the sound-absorbing cotton has a porous structure. These pores allow sound waves to enter the interior of the sound-absorbing cotton and reflect multiple times therein, thereby increasing the contact area between the sound waves and the sound-absorbing cotton material and improving the absorption effect of the sound waves.
