As shown in fig. 2 and 3, the filter mechanism 2: the bidirectional screw rod 201 is arranged along the axial direction of the shell 1, guide rods 202 are arranged on two sides of the bidirectional screw rod 201, the bidirectional screw rod 201 is connected with filter element supports 203 through nuts 208, filter cotton 206 is arranged in the filter element supports 203, the filter cotton 206, the inner wall of the shell 1, the bidirectional screw rod 201 and the guide rods 202 are arranged in a sealing mode, the two groups of filter element supports 203 are symmetrically arranged relative to the bidirectional screw rod 201, and a motor 209 drives the two groups of filter element supports 203 to move relatively through the bidirectional screw rod 201 to extrude air in the shell 1 to be filtered forcibly;
the filter element support 203 is composed of an outer ring, spokes and an inner ring, the inner ring of the filter element support 203 is fixedly sleeved with a sleeve 205, the sleeve 205 is sleeved with a nut 208, the nut 208 is matched and sleeved with a bidirectional screw rod 201, the spokes of the filter element support 203 are provided with sleeves, the sleeves are matched and slidably sleeved with guide rods 202, the peripheral wall of the filter element support 203 is sleeved with a sealing ring 204, the sealing ring 204 is connected with the inner wall of the shell 1 in a sealing and sliding mode, filter cotton 206 is sleeved with the filter element support 203, the sleeve 205 is in threaded connection with a filter element cover plate 207, the filter element cover plate 207 is matched with the filter element support 203 in shape, the filter cotton 206 is clamped by the filter element cover plate 207 and the filter element support 203, and the filter element cover plate 207 is sleeved with the filter element support 203.
The device mainly provides a structure for filtering air, a related motor 209 adopts a stepping motor, and related control electric parts adopt the mature technology and products in the market.
The working principle is as follows: it is first noted that the filter cotton 206 has a filtering resistance, the filter cotton 206 which is more dense has the largest filtering resistance, a certain pressure needs to be applied to force the air to pass through the filter cotton 206 to realize filtering, when the applied pressure is very small or not, the air can be pushed to move by moving the filter cotton 206, therefore, the filtering resistance of the filter cotton 206 must be larger than the opening resistance of the sealing gasket 105 and the sealing belt 106 when the material is selected, otherwise, the device cannot normally operate;
the device drives the bidirectional screw rod 201 to rotate through the motor 209, so that two groups of filter element supports 203 are far away from or close to each other, when the two groups of filter element supports 203 drive two groups of filter cotton 206 to close to each other, because the filter cotton 206 has larger filtering resistance, positive pressure is formed between the filter cotton 206 when the filter cotton 206 rapidly moves relatively, and negative pressure is formed at two sides of the two groups of filter cotton 206 far away from each other, so that the sealing belt 106 is pushed open to discharge air, and meanwhile, the external air pushes the sealing gasket 105 away from the air inlet groove 101 to enter the shell 1;
when the two filter element supports 203 are far away from each other, negative pressure is formed between the two filter cotton 206, the sealing strip 106 is tightly attached to the surface of the edge strip 103 of the exhaust groove 102 under the coordination of the external atmospheric pressure, positive pressure is formed on the two sides, far away from each other, of the two filter cotton 206, the sealing gasket 105 is tightly pressed and attached to the inner wall of the shell 1, air on the two sides, far away from each other, of the filter cotton 206 in the shell 1 is forcibly extruded to pass through the filter cotton 206, the filtered air reaches between the two filter cotton 206, and the whole process is completed inside the shell 1 and is completely isolated from the external space;
when the two filter element brackets 203 approach each other again, the filtered clean air pushes the sealing strip 106 open again to be discharged, and meanwhile, the air to be filtered is sucked in through the air inlet groove 101;
the device filters through the mode of "breathing in, exhaling", compares general air filtering equipment's filter fan: the stepper motor 209 and ball screw attachment of the device operate with significantly less noise than a filter fan operating at high speed, and secondly the device operates with relatively less noise due to the velocity and turbulence of the inlet and exhaust air flow being significantly less than a filter fan rotating at high speed.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
