At present, there are some related technologies for the collection and filtration of microparticles, but there are still many shortcomings, mainly in terms of filtration efficiency, adaptability and flexibility of equipment.

[0003] Existing microparticle collection equipment usually uses traditional filter screens or filter elements to capture particles, such as using fixed filter elements to capture microparticles in the air. However, the filter elements of such devices are usually rigid structures and cannot adapt to shape changes in complex environments, especially in narrow and curved pipes or spaces. The flexibility and adaptability of the equipment are poor, resulting in low filtration efficiency. In addition, most existing filter element materials are single rigid substances that cannot be adaptively adjusted according to environmental changes, which easily causes fluctuations in filtration efficiency under different fluid conditions.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The present invention provides a flexible filter element type bionic microparticle collector, which can be implemented as follows: Figures 1 to 4 As shown, it includes a flexible filter element mechanism 10 and a reciprocating drive mechanism 20; the flexible filter element mechanism 10 includes a plurality of flexible filter threads 11, and the plurality of flexible filter threads 11 are arranged radially; the reciprocating drive mechanism 20 includes a housing 21, a screw rod 22, a slider 23 and a drive motor 24; a screw rod 22 is arranged in the housing 21; a slider 23 is arranged on the outer sleeve of the screw rod 22, and the screw rod 22 and the slider 23 are connected by a threaded transmission; the slider 23 is connected and fixed to the flexible filter element mechanism 10; the drive motor 24 is used to drive the screw rod 22 to rotate, so as to control the plurality of flexible filter threads 11 to move into the housing 21 for bundling and collection, or to control the plurality of flexible filter threads 11 to move out of the housing 21 and restore to a radial arrangement.

[0027] Assuming that in the default state, the multiple flexible filter threads 11 are all stored in the internal space of the outer shell 21. At this time, if it is necessary to collect microparticles in a certain space, the drive motor 24 can be used to control the rotation of the screw rod 22, and the drive slider 23 can drive the multiple flexible filter threads 11 to move to the outside of the outer shell 21; once the multiple flexible filter threads 11 move to the outside of the outer shell 21, the multiple flexible filter threads 11 will automatically return to the initial radial shape to better adsorb the microparticles in the space. At this time, it is only necessary to use the drive motor 24 to control the reversal of the screw rod 22, and drive the slider 23 to drive the multiple flexible filter threads 11 to move to the inside of the outer shell 21, so as to realize the collection of microparticles.

[0028] In this process, the present invention essentially uses tube worms as bionic objects, because tube worms have extremely strong adaptability to complex water environments and can capture and retain suspended particles with a diameter of less than 3 μm, which is consistent with the characteristics that the diameter of most microparticles / microbacteria is between 0.5-5 μm. Therefore, after the bionic design of the present invention, similar performance can be obtained.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the flexible filter element mechanism 10 of this embodiment also includes a positioning block 12, which is provided with a through hole 121 for the screw rod 22 to pass through, and a plurality of flexible filter threads 11 are arranged around the periphery of the through hole 121 on one side of the positioning block 12, and the other side of the positioning block 12 is connected and fixed to the slider 23.

[0030] With this arrangement, the through hole 121 on the positioning block 12 can provide a moving path for the screw rod 22 , ensuring that the slider 23 can smoothly drive the positioning block 12 and the plurality of flexible filter threads 11 to move into or out of the housing 21 .

[0031] like Figure 4As shown, in this embodiment, the flexible filter 11 includes an elastic rod 111 and silk feathers 112; one end of the elastic rod 111 is connected and fixed to the positioning block 12, and the other end of the elastic rod 111 extends in a direction away from the central axis of the positioning block 12; two rows of the silk feathers 112 are respectively connected to both sides of the peripheral wall of the elastic rod 111, and an obtuse angle is formed between the two rows of silk feathers 112, and the obtuse angle is toward the center of the positioning block 12.

[0032] After adopting this setting, the silk feathers 112 will be able to gather toward the center of the positioning block 12, so that when the multiple flexible filter threads 11 move into the shell 21, the silk feathers 112 can better collect the microparticles into the shell 21.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the housing 21 includes a bottom plate 211 and a cylinder wall 212 which are connected to each other; a driving motor 24 is provided on the outer wall of the bottom plate 211, and the driving motor 24 passes through the bottom plate 211 and is connected to the screw rod 22, and a coupling 25 is connected between the driving motor 24 and the screw rod 22; the cylinder wall 212 surrounds the screw rod 22.

[0034] After adopting this arrangement, the bottom plate 211 can be used to install and fix the drive motor 24 , and the cylinder wall 212 can be used to surround the screw rod 22 .

[0035] like Figures 1 to 3 As shown, in this embodiment, a guide groove 213 is provided on the inner peripheral wall of the cylinder wall 212 , and the guide groove 213 is arranged to extend along the axial direction of the screw rod 22 ; a guide block 26 is provided on the outer peripheral wall of the slider 23 , and the guide block 26 is slidably installed in the guide groove 213 .

[0036] After adopting this setting mode, the cooperation between the guide groove 213 and the guide block 26 can realize the limiting of the slider 23, ensuring that after the screw rod 22 rotates, the screw rod 22 can drive the slider 23 to move back and forth.

[0037] like Figures 1 to 3 As shown, in this embodiment, a guide rod 27 is provided inside the cylinder wall 212 , and the guide rod 27 is arranged to extend along the axial direction of the screw rod 22 . One end of the guide rod 27 is connected to the bottom plate 211 , and the other end of the guide rod 27 passes through the guide block 26 .

[0038] After adopting this setting method, the guide rod 27 can be used to limit the moving trajectory of the guide block 26 again, so that the movement of the guide block 26 is more stable and smooth; wherein, the number of guide blocks 26 and guide rods 27 is not unique. For example, in this embodiment, the guide block 26 is provided to include a first guide block 261 and a second guide block 262, which are arranged in a cross shape. Multiple first guide blocks 261 and multiple second guide blocks 262 are alternately arranged on the outer peripheral wall of the slider 23, and the multiple first guide blocks 261 are respectively passed through the guide rods 27, so as to further improve the movement stability of the guide block 26.

[0039] like Figure 2 As shown, in this embodiment, the output shaft of the driving motor 24 is provided with a bearing 28 , and the bearing 28 is arranged between the base plate 211 and the coupling 25 .

[0040] After adopting this configuration, the bearing 28 can be used to improve the rotation smoothness of the output shaft of the drive motor 24 .

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
