Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and specifically relates to a micro lint collecting device and a control method therefor. Background Art

[0002] Micro lint is the clothing fiber debris that rubs off between clothes and between clothes and the washing machine during the clothing washing process. Larger micro lint has a size of several millimeters in length. After being discharged into the water, it will enter the soil, causing soil compaction and affecting the growth of crops. Smaller micro lint has a size of only a few micrometers. Coupled with the widespread popularity of chemical fiber clothing at present, the micro lint generated during its washing process is also called microplastics, which can enter the human blood through the food chain.

[0003] Currently, researchers have found the above-mentioned micro lint in embryonic blood. Although the direct health effects of micro lint on humans are not yet clear, it has attracted the attention of the international community, and research is being stepped up. Out of long-term consideration for human health, in some regions, the discharge of micro lint has been managed step by step. In order to cut off the discharge of micro lint from the source, only the washing equipment such as washing machines can be improved to filter and collect during the discharge of washing water.

[0004] Existing devices used in washing equipment for collecting micro lint, since it is not allowed to discharge the filtered micro lint to the environment through the sewer, often need to be manually collected by the user after filtration and then post-processed. And generally, the above-mentioned devices filter out micro lint together with coarser and larger lint of larger size, resulting in a relatively fast accumulation rate of lint, and the user needs to clean it manually frequently. However, in the current solutions, the filtered lint is often collected in a relatively humid state, and even during the filtration process, it is very easy for some water to enter the above-mentioned cavity together with the lint, resulting in the collected lint being in a humid environment for a long time, and thus prone to mildew and generating odors. Therefore, the user experience in the process of collecting and cleaning micro lint is very poor.

[0005] In addition, the existing structures often separately dispose of micro lint separation and collection, resulting in complex structures, cumbersome control, and affecting the drainage speed.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a micro lint collecting device and a control method therefor, which can reduce or even avoid water flow from entering the chamber for storing micro lint, store the micro lint in a relatively sealed environment, reduce the humidity of the micro lint storage environment, prevent the odor of the micro lint storage from spreading, and can also compress the volume of the micro lint, thereby reducing the number of times the user needs to clean.

[0008] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A micro wire chip collection device, comprising:

[0010] A filtering unit, including a filtering cylinder and a rotating shaft arranged coaxially. The rotating shaft is rotatably and axially movable and installed in the filtering cylinder, and spiral blades are arranged on the circumferential side wall of the rotating shaft;

[0011] A water storage unit, including a water storage shell sleeved outside the filtering cylinder, with a water inlet and a water outlet arranged thereon. A water storage cavity is formed between the inner wall of the water storage shell and the outer wall of the filtering cylinder for accommodating the filtered water;

[0012] A storage unit is arranged outside one end of the water storage shell and is communicated with the inside of the filtering cylinder. A switchable sealing component is arranged between the filtering cylinder and the storage unit;

[0013] A puncturing part is arranged at one end of the rotating shaft close to the sealing component, and is used to move axially along with the rotating shaft to pierce the sealing component to conduct the filtering cylinder and the storage unit;

[0014] The spiral blades are used to rotate along with the rotating shaft to send the micro wire chips inside the filtering cylinder into the storage unit.

[0015] Further, the axis of the filtering cylinder extends in the horizontal direction, or extends obliquely downward from the end where the sealing component is located; the storage unit extends at least partially obliquely downward along the direction away from the filtering cylinder.

[0016] Further, the water inlet is arranged on the lower side of the water storage shell, and the water outlet is arranged on the upper side of the water storage shell;

[0017] A liner is arranged in the water inlet. The lower end of the liner is hermetically connected to the water inlet, and the upper end is connected to the side wall of the filtering cylinder; an opening structure is arranged on the side wall of the filtering cylinder corresponding to the liner.

[0018] Further, the water inlet extends downward from the outer wall of the water storage shell to form a tubular structure, and the liner is hermetically inserted into the tubular structure. The lower end of the liner is higher than the lower end of the tubular structure;

[0019] A drain pipe communicating with the water storage cavity is connected to the bottom of the water storage shell. The water outlet end of the drain pipe is connected to the area on the tubular structure lower than the lower end of the liner; a valve plate that can be turned downward to open is arranged at the water outlet end position of the drain pipe.

[0020] Further, the axis of the filtering cylinder extends in the vertical direction; the water outlet is arranged in the area close to the lower end of the water storage shell;

[0021] The storage unit is connected to the upper end of the filter cartridge. The storage unit is bent downward from the upper end of the filter cartridge and then extends downward.

[0022] Further, filter holes for blocking micro wire chips are provided on the side wall of the filter cartridge; a cutting structure is provided at the edge of the spiral blade close to the side wall of the filter cartridge for cutting off the wire chips stuck in the filter holes.

[0023] Further, the aperture diameter of the filter holes gradually increases from the inner side to the outer side of the filter cartridge.

[0024] Further, one end of the filter cartridge away from the storage unit passes through the end wall of the water storage shell and extends out, and an end cover with a threaded hole in the middle is provided. An axial head is provided at the end of the rotating shaft away from the sealing assembly, and the axial head is installed in the threaded hole;

[0025] The middle part of the axial head along the axis has a threaded section, and the threaded section is in threaded fit connection with the threaded hole; both sides of the axial head on both sides of the threaded section are smooth shaft sections without a threaded structure, and the diameter of the smooth shaft section is smaller than the diameter enclosed by the top of the internal thread in the threaded hole.

[0026] Further, a sealing gasket is sleeved on the rotating shaft in the area close to the axial head, and the outer periphery of the sealing gasket is slidably and sealingly arranged on the inner surface of the side wall of the filter cartridge;

[0027] Concave leather bowl structures are provided on both side surfaces of the sealing gasket, and deformable bowl petals are formed on the outer periphery of the sealing gasket; when the sealing gasket moves along the axis with the rotating shaft, the bowl petals are deformed to strengthen the seal.

[0028] A control method for the above-mentioned micro wire chip collection device, which is applied to a washing device and is used for filtering the drainage water flow of the washing device;

[0029] The washing device passes the drainage water flow into the micro wire chip collection device for filtering. When the washing device stops draining, the rotating shaft is controlled to rotate and move along the axis close to the sealing assembly, driving the puncturing part to move to push open the sealing assembly; the rotating shaft continues to rotate, and the spiral blade rotates with the rotating shaft, and the micro wire chips in the filter cartridge are sent into the storage unit through the pushed-open sealing assembly;

[0030] Or, the filter cartridge is vertically extended, and the water outlet is arranged in the area close to the lower end of the water storage shell; during the process that the washing device passes the drainage water flow into the micro wire chip collection device, the rotating shaft is controlled to rotate and move along the axis close to the sealing assembly, driving the puncturing part to move to push open the sealing assembly; the rotating shaft continues to rotate, and the spiral blade rotates with the rotating shaft, and the micro wire chips in the filter cartridge are sent into the storage unit through the pushed-open sealing assembly.

[0031] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0032] In the present invention, a sealing component is provided between the filter cartridge and the storage unit in the micro-thread scraps collection device. Only when it is necessary to feed the micro-thread scraps into the storage unit, the sealing component is pushed open by the puncture portion, thereby guiding the micro-thread scraps through the filter cartridge and the storage unit. In this way, when it is not necessary to feed the thread scraps, water or moisture in the filter cartridge can be prevented from entering the storage unit, thereby reducing the humidity inside the storage unit and, to a certain extent, avoiding the problem of micro-thread scraps being too wet and moldy. At the same time, the sealing component keeps the micro-thread scraps storage environment sealed, so that even if the micro-thread scraps storage produces odor, the odor can be prevented from emitting, thereby improving the user experience.

[0033] In the present invention, the spiral blades rotate with the shaft to scrape the wire scraps attached to the inner wall of the filter cartridge into the storage unit, thereby cleaning the filter cartridge. By arranging a water storage shell on the outside of the filter cartridge, it is beneficial to increase the area on the filter cartridge that can filter the water flow, thereby improving the filtering efficiency of the water flow, and also improving the filtering capacity of the filter cartridge, thereby reducing the frequency of controlling the micro-wire scraps collection device to clean the filter cartridge.

[0034] In the present invention, for the scheme of horizontal extension of the filter cartridge, by setting a flow path, the residual accumulated water in the water storage chamber can be drained, and the micro-thread chips in the filter cartridge can be prevented from being soaked in water. In the process of the spiral blade rotating to transport the micro-thread chips, it is easier to squeeze and dehydrate the micro-thread chips, and it can also prevent water from entering the storage unit when the sealing component is opened. For the scheme of vertical extension of the filter cartridge, the water level in the water storage chamber can be controlled not to exceed a certain height by the drainage flow rate of the washing equipment, so that the washing equipment can drain water while the micro-thread chip collection device can send the filtered micro-thread chips to the storage unit without causing the problem of water entering the storage unit. Collecting micro-thread chips while draining water is also conducive to ensuring that the drainage efficiency is not reduced.

[0035] In the present invention, the cutting structure arranged on the spiral sheet can cut off the wire scraps stuck in the filter hole on the filter cartridge. With the structure of the filter hole with a small inner diameter and a large outer diameter, the cut wire scraps can be easily washed away from the filter hole by the water flow, effectively avoiding the problem of wire scraps blocking the filter hole.

[0036] In the present invention, a sealing gasket is mounted on the rotating shaft to prevent water leakage from the end of the filter cartridge where the end cap is located. The leather cup structure on the sealing gasket forms a deformable bowl flap. When the sealing gasket moves axially with the rotating shaft, the bowl flap on the surface of one side facing the moving direction bends toward the outer periphery to strengthen the seal, and the bowl flap on the other side bends inward to reduce resistance. In this way, the sealing effect is guaranteed without affecting the axial movement of the rotating shaft.

[0037] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings. Brief Description of the Drawings

Detailed implementation manners

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0052] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0053] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] Such as Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a micro wire debris collection device and a control method thereof. The micro wire debris collection device is applied to a washing device, and can receive the water flow discharged from the washing device for filtration, so as to collect the micro wire debris generated during the working process of the washing device. Among them, the washing device can be a washing machine, a washer-dryer, a nursing machine and other washing devices with clothes washing functions.

[0055] Specifically, the micro wire debris collection device includes a filtering unit 300 and a storage unit 100 that are interconnected, and a water storage unit 500 arranged outside the filtering unit 300. The filtering unit 300 is used to receive the water flow to be filtered for filtration, separate the wire debris or other impurities containing micro wire debris from the water flow, the filtered water is discharged through the water storage unit 500, and the separated impurities such as micro wire debris are sent into the interior of the storage unit 100 for storage.

[0056] However, the micro wire debris separated by filtering the water flow contains a large amount of moisture. If it is sent into the storage unit 100 without any treatment, the interior of the storage unit 100 will be in a highly humid environment for a long time. Moreover, once the water entering the filtering unit 300 overflows into the storage unit 100, the micro wire debris stored in the storage unit 100 will also be soaked in water. Furthermore, at room temperature, the micro wire debris stored for a long time is prone to mildew and generate peculiar smell, affecting the user experience during the cleaning process.

[0057] Embodiment 1

[0058] This embodiment provides a micro wire debris collection device, which is used to solve the problem that the storage environment of the micro wire debris is too humid and prone to mildew and generate peculiar smell, affecting the user cleaning experience.

[0059] Specifically, as Figures 1 to 7 shown, in the micro wire debris collection device of this embodiment, the filtering unit 300 includes a filtering cylinder 370 and a rotating shaft 320 arranged coaxially. The rotating shaft 320 is rotatable and is installed in the filtering cylinder 370 so as to move along its axis. A spiral blade 310 is arranged on the side wall of the rotating shaft 320. The water storage unit 500 includes a water storage shell 550 sleeved outside the filtering cylinder 370, on which a water inlet 520 and a water outlet 530 are arranged. A water storage cavity 510 is formed between the inner wall of the water storage shell 550 and the outer wall of the filtering cylinder 370 for accommodating the filtered water.

[0060] The storage unit 100 is arranged at one end of the water storage shell 550 (that is Figure 1 and Figure 2outside the left end of [], and is communicated with the inside of the filter cartridge 370. A closable sealing assembly is provided between the filter cartridge 370 and the storage unit 100. A puncturing portion 221 is provided at one end of the rotating shaft 320 close to the sealing assembly. When the rotating shaft 320 moves along its axis, the puncturing portion 221 can be driven to move synchronously. When the puncturing portion 221 moves leftward with the rotating shaft 320, the sealing assembly can be pushed open, thereby guiding the communication between the filter cartridge 370 and the storage unit 100. The spiral blade 310 provided on the side wall of the rotating shaft 320 can rotate synchronously with the rotating shaft 320, so as to send the micro wire chips accumulated in the filter cartridge 370 into the storage unit 100 along its advancing direction.

[0061] As a specific implementation manner, both the filter cartridge 370 and the water storage shell 550 are cylindrical. The side wall of the water storage shell 550 and the side wall of the filter cartridge 370 are arranged at intervals to form the water storage cavity 510. The side wall of the filter cartridge 370 has a filtering portion 380, on which a plurality of filtering holes 381 are opened. The water to be filtered directly enters the inside of the filter cartridge 370 through the water inlet 520. The water flows through the filtering holes 381 and enters the water storage cavity 510, and finally is discharged through the water outlet 530. The micro wire chips and other impurities in the water are intercepted inside the filter cartridge 370, realizing the separation of the micro wire chips from the water.

[0062] The outer diameter of the spiral blade 310 is basically the same as the inner diameter of the filter cartridge 370, and the two are in a small-gap fit. By driving the rotating shaft 320 to rotate in the first direction to drive the spiral blade 310 to rotate synchronously, the micro wire chips attached to the inner wall of the filter cartridge 370 can be scraped off by the spiral blade 310, and the micro wire chips can be pushed to concentrate at the left end of the filter cartridge 370. The process of scraping off the micro wire chips by the spiral blade 310 can also exert a certain squeezing effect on the micro wire chips to squeeze out the water in the micro wire chips, further reducing the moisture content of the micro wire chips when they enter the storage unit 100.

[0063] Preferably, the rotating shaft 320 can also be driven to rotate in a second direction opposite to the first direction. At this time, the spiral blade 310 rotates synchronously with the rotating shaft 320 to concentrate the micro wire chips at the right end of the filter cartridge 370 and realize the squeezing and dehydration of the micro wire chips. Then, by driving the rotating shaft 320 to rotate in the first direction, the squeezed and dehydrated micro wire chips can be conveyed to the left until they are sent into the storage unit 100 for storage.

[0064] During the process of the rotating shaft 320 rotating in the first direction, it also moves leftward along its axis, driving the puncturing part 221 at its left end to move leftward synchronously, so as to push open the sealing assembly between the filter cartridge 370 and the storage unit 100. In this way, the filter cartridge 370 is communicated with the storage unit 100, and the fine wire chips in the filter cartridge 370 can be sent into the storage unit 100 for storage. When it is not necessary to send fine wire chips into the storage unit 100, the puncturing part 221 does not act on the sealing assembly, so that it remains in a blocked state. Furthermore, the storage unit 100 is completely separated from the filter cartridge 370, and the water flow or moisture in the filter cartridge 370 can be prevented from entering the storage unit 100.

[0065] Through the above solution, when it is not necessary to send fine wire chips into the storage unit 100, the storage unit 100 is a sealed structure as a whole, thus effectively ensuring the low moisture state of the internal environment of the storage unit 100 and effectively preventing the problem that the fine wire chips mildew after being stored in a high humidity environment for a long time. In addition, by maintaining the sealed state of the storage unit 100 relative to the outside through the sealing assembly, even if the fine wire chips produce peculiar smell during storage, the peculiar smell can be prevented from spreading, improving the user experience.

[0066] At the same time, since the water storage shell 550 is arranged outside the filter cartridge 370 in this embodiment, the filtering part 380 with filtering holes 381 can be arranged on a large area of the side wall of the filter cartridge 370, so as to improve the filtering efficiency of the water flow. On the other hand, the permeable area of the filter cartridge 370 is increased, which is equivalent to improving the filtering capacity of the filter cartridge 370, and a larger amount of fine wire chips can be collected inside the filter cartridge 370 without worrying about the blockage of the filtering part 380.

[0067] In a further solution of this embodiment, the axis of the filter cartridge 370 extends along the horizontal direction or close to the horizontal direction. The storage unit 100 extends at least partially obliquely downward in a direction away from the filter cartridge 370. In this way, the position of the storage unit 100 is lower at the end away from the filter cartridge 370, which is beneficial to preventing the fine wire chips from accumulating at the inlet of the storage unit 100.

[0068] Preferably, the filter cartridge 370 is arranged with its axis inclined relative to the horizontal direction, and its axis extends obliquely downward from the end where the sealing assembly is located, so that the left end of the filter cartridge 370 is higher than the right end. There is a certain included angle between the axis of the filter cartridge 370 and the horizontal direction, such as being installed at 15°. In this way, when the sealing assembly is pushed open, the risk of water flow entering the storage unit 100 is further reduced.

[0069] In a specific solution of this embodiment, the sealing assembly includes a sealing door 130 made of an elastic material. The sealing door 130 is sealingly installed on the storage unit 100 at the opening for connecting the filter cartridge 370, or installed on the filter cartridge 370 at the opening for connecting the storage unit 100. A cut is provided on the sealing door 130. The puncturing part 221 moves leftward along with the rotating shaft 320 and passes through the sealing door 130 through the cut. The sealing door 130 forms a gap for communicating the filter cartridge 370 and the storage unit 100 at the position of the cut.

[0070] As a preferred implementation manner of this embodiment, the storage unit 100 includes a storage cylinder 110 made of a hard material and a flexible connecting part 120. The inner cavity of the storage cylinder 110 is used for storing micro wire chips. The right end of the connecting part 120 is connected to a hard segment, and the left end of the filter cartridge 370 is connected through the hard segment. Due to the flexible nature of the connecting part 120, it can be deformed, thereby facilitating the adjustment of the angle of the storage cylinder 110 to make it in a state where the right end is high and the left end is low, preventing the micro wire chips from accumulating at the inlet of the storage unit 100. A desiccant can be pre-placed in the storage cylinder 110 to absorb the residual moisture in the micro wire chips and the water vapor entering when the sealing assembly is briefly opened when feeding the micro wire chips, further ensuring a low moisture state inside the storage unit 100.

[0071] The sealing door 130 is installed in the storage unit 100, specifically in the hard segment at the right end of the connecting part 120. The outer periphery of the sealing door 130 is sealingly connected to the inner wall of the hard segment. A first opening 541 is provided at the center of the left end wall of the water storage shell 550. The filter cartridge 370 is installed in the first opening 541, and the joint between the two is in interference fit to achieve fixation and sealing. The hard segment of the storage unit 100 and the filter cartridge 370 are detachably connected. When the micro wire chips in the storage cylinder 110 are full, the user can manually remove the storage unit 100 for replacement. During the process of the user replacing the storage unit 100, since the inlet of the storage unit 100 is blocked by the sealing door 130, even if the wire chips stored inside produce an odor, it will not escape, improving the user experience.

[0072] As a specific solution of this embodiment, refer to Figure 4 and Figure 5, the incision on the sealing door 130 includes a longitudinal incision 131 and a transverse incision 132 that are perpendicularly arranged. The sealing door 130 is integrally a disc-shaped structure made of flexible rubber or silica gel. A longitudinal incision 131 and a transverse incision 132 are arranged in the middle area to form a cross-shaped incision structure. Without external force, the cross-shaped incision remains in close contact and is in an airtight state, ensuring the sealed state inside the storage cylinder 110. When the puncturing part 221 presses from the right side, it can be opened from the position of the cross-shaped incision, so that micro wire chips can be fed into the storage cylinder 110. At the same time, the sealing door 130 can closely fit on the surface of the puncturing part 221, reducing the moisture entering the storage cylinder 110 from the gap between the sealing door 130 and the puncturing part 221. When the puncturing part 221 moves to the right and withdraws, the cross-shaped incision automatically closes, and the storage cylinder 110 resumes the sealed state.

[0073] Further, in this embodiment, the water inlet 520 is arranged on the lower side of the water storage shell 550, and the water outlet 530 is arranged on the upper side of the water storage shell 550. A liner 521 is arranged inside the water inlet 520. The lower end of the liner 521 is hermetically connected to the water inlet 520, and the upper end is connected to the side wall of the filter cylinder 370. An opening structure 371 is arranged on the side wall of the filter cylinder 370 corresponding to the liner 521. In this way, the water to be filtered entering from the water inlet 520 can be directly injected into the interior of the filter cylinder 370.

[0074] As a specific implementation manner, the water inlet 520 is formed by extending downward from the outer wall of the water storage shell 550 to form a tubular structure, and the liner 521 is hermetically inserted into the tubular structure, and the lower end of the liner 521 is higher than the lower end of the tubular structure.

[0075] More specifically, the opening structure 371 is arranged near the right end of the filter cylinder 370, and the water outlet 530 is arranged in the middle area in the axial direction of the water storage shell 550, that is, the water inlet 520 and the water outlet 530 are arranged in an axial staggered manner along the water storage shell 550.

[0076] In the above solution, the micro wire chip collection device filters in the way of water inlet from the lower side and water outlet from the upper side. It is necessary for the water storage cavity 510 to be nearly filled with water to drain outward. Furthermore, during the filtering process, the water entering the filter cylinder 370 is more likely to fill the filter cylinder 370, making full use of the coverage area of the filtering part 380 on the filter cylinder 370. The water to be filtered enters the filter cylinder 370 from the right end far from the sealing component, and it is easier to collect more micro wire chips in the area between the opening structure 371 and the compression hopper 220 in the filter cylinder 370.

[0077] In a further embodiment of the present invention, the puncturing part 221 has a hollow structure inside. The fine wire chips accumulated in the filter cylinder 370 can be pushed by the spiral blade 310 into the inside of the puncturing part 221, and finally discharged from the left end of the puncturing part 221 passing through the sealing door 130 and enter the storage cylinder 110.

[0078] Specifically, the fine wire chip collecting device of this embodiment further includes a compression hopper 220 arranged near the left end inside the filter cylinder 370. The compression hopper 220 can move along the axis direction of the filter cylinder 370 following the rotation shaft 320. The compression hopper 220 has a funnel-shaped structure with a gradually decreasing diameter from right to left, and a puncturing part 221 is formed at the small-diameter end of the funnel-shaped structure.

[0079] Both ends of the funnel-shaped structure are open, and there is a compression channel with an inner diameter gradually decreasing from right to left inside. When the spiral blade 310 rotates, the fine wire chips are sent into the compression channel from the large-diameter end (i.e., the right end in the figure) of the funnel-shaped structure. After being compressed through the compression channel, the fine wire chips are discharged from the small-diameter end of the compression channel and enter the storage cylinder 110 of the storage unit 100.

[0080] More specifically, the compression hopper 220 includes a guiding part 223, a compression neck 222 and a puncturing part 221 connected in sequence from right to left. Among them, the compression neck 222 and the puncturing part 221 form the funnel-shaped structure. When the fine wire chips pass through the inside of the compression neck 222, they are compressed, gradually become thinner and have a higher density, so as to reduce the volume and facilitate passing through the sealing door 130. The compression neck 222 can be Figure 3 the arc transition structure as shown in

[0081] The guiding part 223 is a cylindrical shape extending to the right from the right end of the compression neck 222. The outer diameter of the guiding part 223 has a clearance fit with the inner diameter of the filter cylinder 370. When the compression hopper 220 moves along the axis following the rotation shaft 320, the guiding part 223 cooperates with the side wall of the filter cylinder 370, which can ensure that the tip of the left end of the puncturing part 221 is always located on the axis of the filter cylinder 370, that is, always facing the intersection of the longitudinal incision 131 and the transverse incision 132 on the sealing door 130.

[0082] Preferably, a layer of material such as nylon can be covered on the outer periphery of the guiding part 223 to achieve sealing with the inner wall of the filter cylinder 370 while lubricating. In this way, water will not accumulate on the outer peripheries of the compression neck 222 and the puncturing part 221, further avoiding the water flow in the filter cylinder 370 from entering the storage unit 100.

[0083] In this embodiment, when the rotating shaft 320 moves leftward to drive the compression hopper 220 to move leftward synchronously, the left end of the puncturing part 221 first presses against the cross-shaped incision of the sealing door 130. The rotating shaft 320 continues to push the compression hopper 220 leftward, and the puncturing part 221 will penetrate the sealing door 130 and extend into the storage unit 100. At this time, the fine wire chips sent into the interior of the compression hopper 220 as the spiral blade 310 rotates are compressed, extruded from the puncturing part 221 into the storage unit 100, slightly increase in volume, accumulate to a certain length, and then break at the open end of the puncturing part 221, and finally enter the storage unit 100 in a section-by-section state.

[0084] In the above manner, the fine wire chips do not come into contact with the sealing door 130 at all when entering the storage unit 100, and also avoid the problem that the fine wire chips remain at the cross-shaped incision of the sealing door 130 and affect the sealing performance of the sealing door 130.

[0085] Further, in order to send all the fine wire chips accumulated in the filter cylinder 370 into the storage unit 100 as much as possible through the spiral blade 310, the outer diameter of the spiral blade 310 is basically the same as the inner diameter of the filter cylinder 370, so that the two are fitted with a small gap. In this way, the fine wire chips attached to the inner wall of the filter cylinder 370 can be fully scraped off by the spiral blade 310 without affecting the rotation of the spiral blade 310.

[0086] The spiral blade 310 needs to extend into the interior of the compression hopper 220 in order to send the fine wire chips into the compression channel inside the compression hopper 220 for compression. For this reason, the diameter of the leftmost section of the spiral blade 310 is smaller than that of other regions. Specifically, the outer diameter of the leftmost section of the spiral blade 310 is basically the same as the inner diameter of the guiding part 223, and the two are fitted with a small gap. When the rotating shaft 320 moves leftward, the left end of the spiral blade 310 abuts against the inner wall of the compression neck 222, thereby pushing the entire compression hopper 220 to move leftward, causing the puncturing part 221 to push open the sealing door 130.

[0087] Further, an elastic member is also provided in the filter cylinder 370 for applying an elastic force to the compression hopper 220, so that when the rotating shaft 320 moves rightward, the compression hopper 220 is reset rightward under the action of the elastic force, so that the puncturing part 221 withdraws from the cross-shaped incision of the sealing door 130, and the sealing door 130 resumes sealing.

[0088] Specifically, the elastic member is a compression spring 230 sleeved on the compression hopper 220, and an annular support piece 210 is provided on the right side of the sealing door 130. The left end of the compression spring 230 abuts against the support piece 210, and the right end abuts against the large-diameter part of the compression neck 222. The rotating shaft 320 moves leftward to push the compression hopper 220 to move leftward, compressing the left compression spring 230. When the rotating shaft 320 moves rightward, the elastic force of the compression spring 230 pushes the compression hopper 220 to reset rightward.

[0089] In this embodiment, the fine wire chips are compressed in volume and then sent to the storage unit 100 for storage. On the one hand, the water carried in the fine wire chips can be further extruded during the compression process, thereby further reducing the water content of the fine wire chips. On the other hand, the space occupied by the fine wire chips after being compressed in volume is reduced, which can increase the amount of fine wire chips that can be stored in the storage unit 100, reduce the replacement frequency of the user, and improve the user experience. Even more, through the reasonable design of the volume of the storage cylinder 110, the storage cylinder 110 can be made to store enough fine wire chips that can be collected, so that the user does not need to replace it during the life cycle of the washing device, and the user experience is better.

[0090] The fine wire chip collecting device of this embodiment has the above structure, and cooperates with the inclined installation of the axis of the filter cylinder 370, so that the left end of the filter cylinder 370 is higher than the right end. In this way, the water entering the filter cylinder 370 will not easily submerge the puncture part 221, and it is possible to avoid re-wetting some of the fine wire chips remaining in the puncture part 221 that have been squeezed dry. On the other hand, when the rotating shaft 320 does not rotate, the water and fine wire chips in the filter cylinder 370 can also be left in the right end area of the filter cylinder 370, which is convenient for squeezing out the water.

[0091] In this embodiment, in order to drive the rotating shaft 320, the fine wire chip collecting device further includes a transmission unit 600 and a driving unit 700. The driving unit 700 provides a driving force, and drives the rotating shaft 320 to rotate through the transmission of the transmission unit 600. The transmission unit 600 and the driving unit 700 are both arranged outside the water storage shell 550, and a second opening 542 is provided on the end wall of the water storage shell 550 far from the storage unit 100 (that is, Figure 1 and Figure 2 the right end in

[0092] In this embodiment, the rotating shaft 320 can not only rotate around its own axis, but also move along the axis. And when the rotating shaft 320 moves to the left to the limit position, it can continue to rotate to continuously send the fine wire chips into the storage unit 100. For this reason, the fine wire chip collecting device of this embodiment further includes the following structure.

[0093] A end cap 360 with a threaded hole in the middle is provided at the right end of the filter cartridge 370 extending out of the water storage shell 550. A shaft head 330 is provided at the right end of the rotating shaft 320, and the shaft head 330 is installed in the threaded hole. The middle part of the shaft head 330 in the axial direction has a threaded section 331, and the threaded section 331 is in threaded fit connection with the threaded hole. On both sides of the threaded section 331 of the shaft head 330 are smooth shaft sections without threaded structures, and the diameter of the smooth shaft section is smaller than the diameter enclosed by the top of the internal thread in the threaded hole.

[0094] With the above structure, by driving the rotation of the rotating shaft 320, the threaded section 331 on the shaft head 330 can be matched with the threaded hole on the end cap 360, so that the rotating shaft 320 generates a movement along the axial direction while rotating. Specifically, the helix direction of the helical structure on the threaded section 331 and the helix direction of the helical blade 310 on the rotating shaft 320 are set such that when the rotating shaft 320 rotates in the first direction, the shaft head 330 can drive the rotating shaft 320 to move leftward, and at the same time the helical blade 310 rotates to convey the micro wire chips in the filter cartridge 370 leftward.

[0095] The smooth shaft sections provided on both sides of the threaded section 331 ensure that after the rotating shaft 320 moves a certain distance in the axial direction, it can remain stationary in the axial direction, but the rotation of the rotating shaft 320 is not affected.

[0096] Specifically, when the water flow carrying micro wire chips enters the filter cartridge 370, the micro wire chip collection device is in Figure 1 the collection and filtration state shown in the figure. At this time, the rotating shaft 320 is in a position closer to the right side, the puncture part 221 is spaced from the sealing door 130, and the storage unit 100 remains in a sealed state.

[0097] When it is necessary to send the micro wire chips into the storage unit 100, drive the rotating shaft 320 to rotate in the first direction, see Figure 2 , the threaded section 331 will be screwed into the threaded hole of the end cap 360. Since the end cap 360 is fixed, the rotating shaft 320 will be driven by the shaft head 330 to move leftward, and push the compression hopper 220 to squeeze the compression spring 230, so that the puncture part 221 penetrates the sealing door 130. And when the threaded section 331 completely rotates out of the threaded hole, at this time, continue to drive the rotating shaft 320 to rotate, the rotating shaft 320 will no longer move leftward, and the micro wire chips accumulated in the filter cartridge 370 will be continuously pushed leftward by the rotation of the helical blade 310 and sent into the compression hopper 220, and then compressed into a compact solid. After being disconnected section by section from the opening of the puncture part 221, it enters the storage unit 100.

[0098] After the micro wire chips are compressed and conveyed, the driving rotating shaft 320 rotates in the second direction. Since the compression spring 230 always acts on the compression hopper 220 and transmits the force to the rotating shaft 320, the threaded section 331 can quickly cut into the threaded hole in the middle of the end cover 360. Then, the shaft head 330 and the rotating shaft 320 rotate in the second direction synchronously, and the rotating shaft 320 can be driven by the shaft head 330 to move to the right to reset. At the same time, the compression spring 230 pushes the compression hopper 220 to reset to the right, so that the puncture part 221 withdraws from the cross-shaped incision of the sealing door 130, and the sealing door 130 restores the sealed state of the storage unit 100.

[0099] In this embodiment, after a certain amount of micro wire chips accumulate inside the filter cylinder 370, the rotating shaft 320 can also be driven to rotate in the second direction first. After a period of time, since the smooth shaft section on the left side of the threaded section 331 is inside the threaded hole of the end cover 360, the rotating shaft 320 only rotates and no longer generates axial movement. During this process, the spiral blade 310 rotates in the second direction synchronously, which can push the micro wire chips inside the filter cylinder 370 to gradually gather towards the right end of the filter cylinder 370 and plays a role in squeezing and dehydrating the micro wire chips. Then, the rotating shaft 320 is driven to rotate in the first direction, and the threaded section 331 is screwed into the threaded hole on the end cover 360 until it is completely screwed out, so that the shaft head 330 drives the rotating shaft 320 to move a certain distance to the left and keeps rotating continuously. At this time, the puncture part 221 pushes open the sealing door 130, and at the same time, the spiral blade 310 keeps rotating to convey the micro wire chips to the left end of the filter cylinder 370 and finally sends the micro wire chips into the storage unit 100.

[0100] In the above solution, the shaft head 330 has a structure with a threaded section 331 in the middle and smooth shaft sections at both ends, which not only realizes the purpose of driving the rotating shaft 320 to move left and right, but also avoids self-locking when the rotating shaft 320 moves to the left and right extreme positions, resulting in difficult rotation.

[0101] Further, in this embodiment, the transmission unit 600 of the micro wire chip collection device includes a transmission shaft 620, which drives the rotating shaft 320 to rotate around its own axis through the transmission of the transmission shaft 620. Specifically, a connection hole 332 is provided on the shaft head 330, and the left end of the transmission shaft 620 is axially slidably inserted into the connection hole 332 and is circumferentially limited and matched with the connection hole 332.

[0102] More specifically, the shaft head 330 is provided with an installation hole with an open right end face. A spline sleeve is arranged inside the installation hole, and the connection hole 332 is formed inside the spline sleeve. The transmission shaft 620 has a spline structure matching the spline sleeve at least within a certain length range at the left end, so that it can cooperate with the spline sleeve, can move left and right without affecting torque transmission.

[0103] As a specific implementation manner of this embodiment, a worm and worm gear transmission structure is adopted to drive the rotation of the rotating shaft 320. Specifically, the driving unit 700 includes a motor 710 and a worm 720. The worm 720 is coaxially arranged with the output shaft of the motor 710 and is connected to the end of the output shaft. The transmission unit further includes a worm gear 610 coaxially fixed with the transmission shaft 620. The worm gear 610 is arranged above the worm 720 and is in transmission cooperation with it. In this way, when the motor 710 drives the worm 720 to rotate, the worm gear 610 can be driven to rotate, and then the transmission shaft 620 rotates synchronously with the worm gear 610, driving the shaft head 330 to rotate.

[0104] More specifically, the transmission unit 600 further includes a fixed mounting base 630. The transmission shaft 620 passes through the worm gear 610. The left end of the transmission shaft 620 is inserted into the connection hole 332 of the shaft head 330, and the right end is rotatably fixed on the base 630.

[0105] In the above solution, the cooperation between the worm gear 610 and the worm 720 can achieve self-locking, has a large transmission ratio, and the transmission shaft 620 is not collinear with the output shaft of the motor 710. In this way, when compressing the micro wire chips, the extrusion reaction force will not be transmitted to the output shaft of the motor 710, and the structure is more reliable.

[0106] It can be understood that the micro wire chip collection device can also adopt a rotating gear transmission or directly drive the rotation of the rotating shaft by a high-torque motor.

[0107] In this embodiment, since a threaded hole is provided on the end cover 360 at the right end of the filter cylinder 370, that is, it has an open structure. In order to prevent water from leaking from the right end of the filter cylinder 370, a sealing gasket 340 is sleeved on the rotating shaft 320 in the area close to the shaft head 330. The outer periphery of the sealing gasket 340 is slidably and sealingly arranged on the inner surface of the circumferential side wall of the filter cylinder 370, so that it neither affects the reciprocating movement of the rotating shaft 320 in the axial direction nor can prevent water from leaking from the right end of the filter cylinder 370.

[0108] Further, referring to Figure 6 , a shaft hole 344 is provided in the middle of the sealing gasket 340, and the rotating shaft 320 is sealingly inserted into the shaft hole 344. The outer diameters of the sealing gasket 340 and the rotating shaft 320, as well as the inner diameter of the filter cylinder 370, all adopt an interference fit to ensure the sealing reliability.

[0109] In a further solution, a sealing surface 341 that fits with the inner wall of the filter cylinder 370 is formed on the outer peripheral side surface of the sealing gasket 340. Concave leather cup structures are provided on both the left and right side surfaces of the sealing gasket 340, so that deformable bowl petals 343 are formed on the outer periphery of the sealing gasket 340. When the sealing gasket 340 moves axially along with the rotating shaft 320, the bowl petals 343 are deformed to strengthen the sealing.

[0110] Specifically, the cup leather structure is formed by an annular groove provided on the surface of the gasket 340, so as to form a circle of cup petals 343 on the outer periphery of the gasket 340. When the gasket 340 moves to the right along with the rotating shaft 320, under the action of the frictional force between the sealing surface 341 and the inner wall of the filter cylinder 370, the cup petals 343 on the right side of the gasket 340 tilt outward toward the outer periphery, which can enhance the sealing effect; while the cup petals 343 on the left side of the gasket 340 bend inward, which can reduce the frictional resistance with the filter cylinder 370. Conversely, when the gasket 340 moves to the left along with the rotating shaft 320, the cup petals 343 on the left side bend outward toward the outer periphery to enhance the sealing, while the cup petals 343 on the right side bend inward to reduce the resistance.

[0111] Preferably, an inwardly concave oil groove 342 is provided on the outer peripheral side surface of the gasket 340 between the cup petals 343 on both sides, and grease is filled therein. During the movement of the gasket 340 along with the rotating shaft 320, the grease in the oil groove 342 can also play a role in reducing the resistance and sealing.

[0112] As a specific implementation manner, a shaft shoulder 321 extending outward toward the outer periphery is provided on the side wall of the rotating shaft 320, and the gasket 340 is sleeved on the right side of the shaft shoulder 321 on the rotating shaft 320. On the right side of the gasket 340, a gasket 350 is also sleeved on the rotating shaft 320, so as to clamp the gasket 340 between the shaft shoulder 321 and the gasket 350. Through the clamping action of the shaft shoulder 321 and the gasket 350 on the gasket 340, it is further ensured that during the left and right movement of the gasket 340 along with the rotating shaft 320, there is no relative sliding between the gasket 340 and the rotating shaft 320, thereby ensuring the sealing effect of the fit between the outer periphery of the gasket 340 and the inner wall of the filter cylinder 370.

[0113] In a further solution of this embodiment, the filtering part 380 on the filter cylinder 370 surrounds in a circumferential direction for one week, and the extending length of the filtering part 380 in the axial direction is less than the total length of the filter cylinder 370. Specifically, the leftmost end of the filtering part 380 does not exceed the position where the right end of the guiding part 223 of the compression hopper 220 is located in the state of collecting and filtering (that is, when the rotating shaft 320 and the compression hopper 220 are located at the extreme rightward movement position), and the rightmost end of the filtering part 380 does not exceed the position where the left side surface of the gasket 340 is located in the state of compression and conveying (that is, when the rotating shaft 320 is located at the extreme leftward movement position).

[0114] Thus, when the rotating shaft 320 and the compression hopper 220 reciprocate in the filter cylinder 370, the filtering part 380 is always in the area between the rightmost end of the compression hopper 220 and the leftmost side of the gasket 340. Since the filtering holes 381 penetrating through the inner and outer sides of the filter cylinder 370 are provided on the filtering part 380, this setting method can, on the one hand, prevent the water in the water storage cavity 510 from entering the left side of the compression hopper 220 through the filtering holes 381 and then entering the storage unit 100 when the sealing door 130 is opened, and on the other hand, prevent the water in the water storage cavity 510 from entering the right side of the gasket 340 through the filtering holes 381, thereby causing water leakage between the shaft head 330 and the end cover 360.

[0115] In this embodiment, the filtering accuracy of the filtering part 380 is determined by the aperture of the filtering holes 381, and the aperture should be set to at least intercept the micro wire chips in the water.

[0116] In a further solution of this embodiment, the spiral blade 310 has a cutting structure at the edge close to the side wall of the filter cylinder 370. During the rotation of the spiral blade 310 with the rotating shaft 320, the cutting structure passes across the inner surface of the side wall of the filter cylinder 370, and can cut off the wire chips stuck in the filtering holes 381.

[0117] Specifically, the top end of the spiral blade 310 has a certain width, and there is a certain angle between the top end of the spiral blade 310 and the spiral surface of the spiral blade 310, forming the cutting structure similar to a shaving blade. In this way, when the spiral blade 310 rotates with the rotating shaft 320, the top end of the spiral blade 310 passes across the inner surface of the side wall of the filter cylinder 370, and can cut off the wire chips that have penetrated into the filtering holes 381 on the filtering part 380, just like a shaver shaving off the beard through the mesh cover, realizing the self-cleaning of the filtering part 380 and avoiding the blockage of the filtering part 380 by wire chips.

[0118] It can be understood that although the wire chips cut off and located in or outside the filtering holes 381 will be flushed into the water storage cavity 510 and finally discharged with the water flow, the wire chips that can be mixed into the water and discharged indicate that their diameters are smaller than the aperture of the filtering holes 381, and the wire chips of this size are the wire chips allowed to be discharged by regulations.

[0119] In a preferred solution of this embodiment, see Figure 7 , the aperture of the filtering holes 381 gradually increases from the inside to the outside of the filter cylinder 371, forming a frustum-shaped structure. After the wire chips stuck in the filtering holes 381 are cut off, when the inside of the filter cylinder 370 is filled with water, the cut-off wire chips are easily washed away from the filtering holes 381 by the water flow, effectively avoiding the problem of blockage of the filtering holes 381 by wire chips.

[0120] Preferably, the filter cartridge 370 is made of stainless steel, which is wear-resistant and corrosion-resistant. A plurality of through holes penetrating inside and outside are provided in the middle section of the side wall of the filter cartridge 370 as the filter holes 381, and the area where the filter holes 381 are concentrated is denoted as the filter part 380. The filter cartridge 370 made of stainless steel is also easy to process the filter holes 381 thereon to form the filter part 380. At the same time, since only tensile force is borne in the middle section of the filter cartridge 370 and it does not need to cooperate with the compression hopper 220 at the left end or the gasket 340 at the right end, only setting the filter holes 381 in the middle section area can also ensure the overall firmness of the filter cartridge 370.

[0121] When the micro wire debris collection device provided in this embodiment is applied to a washing device, the drain water of the washing device can be passed through the water inlet 520 into the micro wire debris collection device, and after filtering out the micro wire debris, it is discharged from the water outlet 530.

[0122] Specifically, a water inlet pipe is connected to the water inlet 520, and the drain water of the washing device flows along the water inlet pipe to the water inlet 520, and then is injected into the filter cartridge 370. A drain pipe is connected to the water outlet 530 to discharge the filtered water. Both the water inlet 520 and the water outlet 530 are formed as tubular structures extending outward from the outer wall of the water storage shell 550, which is convenient for connecting with the water inlet pipe and the drain pipe.

[0123] In this embodiment, the micro wire debris collection device can be built into the washing device and directly connected to the drain pipeline of the washing device; it can also be placed outside the washing device, that is, the drain pipeline used for draining water from the washing device is connected to the water inlet 520, and the drain pipe connected to the water outlet 530 can be inserted into the floor drain in the user's home.

[0124] When the micro wire debris collection device is applied to a washing device, the following control method is specifically adopted to separate micro wire debris from the drain water of the washing device and collect and store it.

[0125] The washing device performs a drainage operation, and passes the drain water into the micro wire debris collection device for filtering. When the washing device stops draining, the control shaft 320 is rotated and moves along the axis close to the sealing assembly, driving the puncturing part 221 to move to open the sealing assembly. The control shaft 320 continues to rotate, and the spiral blade 310 rotates with the control shaft 320, and the micro wire debris in the filter cartridge 370 is sent into the storage unit 100 through the opened sealing assembly.

[0126] Specifically, after each drainage operation of the washing device is completed, the control motor 710 is started, and the transmission unit 600 drives the rotating shaft 320 to rotate in the first direction. During the rotation of the rotating shaft 320, the shaft head 330 cooperates with the threaded hole on the end cover 360, driving the rotating shaft 320 to move leftward, pushing the compression hopper 220 leftward, and the piercing part 221 penetrates the sealing door 130 at the cross-shaped incision. The motor 710 continues to operate. When the optical axis section on the shaft head 330 enters the threaded hole area of the end cover 360, the rotating shaft 320 no longer moves leftward but can continue to rotate, and then continuously sends the fine lint inside the filter cylinder 370 into the storage unit 100 through the spiral blade 310.

[0127] The motor 710 is started after each drainage operation of the washing device to clean the fine lint accumulated in the filter cylinder 370 and send it into the storage unit 100 for storage, ensuring that the filtering part 380 is always fresh and preventing the problem that the drainage water flow of the washing device cannot be quickly discharged after entering the filter cylinder 370, thereby not reducing the drainage efficiency of the washing device. Usually, at least three drainage operations are required in one washing cycle, so that the fine lint collection device can clean the filter cylinder 370 three times.

[0128] In this embodiment, the fine lint collection device can squeeze out most of the water from the collected fine lint and then compress it for storage, and the storage cylinder 110 for storing the fine lint can be kept in a sealed state, enabling the storage of fine lint in a low-moisture state, which is beneficial to preventing the problem of fine lint from getting moldy due to dampness. The storage unit 100 uses the sealing door 130 to maintain a sealed state. When the user needs to manually replace the storage unit 100, it can well isolate the spaces inside and outside the storage unit 100, avoiding the odor that may be generated by the storage of lint and improving the user experience.

[0129] Embodiment Two

[0130] As Figures 3 to 9 shown, this embodiment is a further limitation of the above Embodiment One. The water storage shell 550 is connected with a drain pipe 560 in the bottom area for completely discharging the residual accumulated water in the water storage cavity 510, preventing the fine lint in the filter cylinder 370 from being soaked in water.

[0131] Specifically, the water inlet end of the drain pipe 560 is connected to the bottom of the water storage shell 550, thus communicating with the water storage cavity 510. The water outlet end of the drain pipe 560 is connected to the tubular structure formed by extending the water inlet 520, and the connection position is lower than the lower end of the lining tube 521. In this way, after stopping the water supply to the fine lint collection device, the residual accumulated water in the water storage cavity 510 can be discharged along the drain pipe 560, ensuring that the water storage cavity 510 is in a waterless state.

[0132] Since the water outlet 530 is arranged on the upper side of the water storage shell 550, after the water inlet stops, the water level in the water storage cavity 510 is usually in a relatively high state, and the liquid level will submerge the filter cylinder 370. Since the filter part 380 of the filter cylinder 370 has filter holes 381 that connect the inside of the filter cylinder 370 with the water storage cavity 510, the micro wire chips inside the collection cylinder 370 will be soaked in water. If the rotating shaft 320 is directly driven to rotate in this state, it is not conducive to squeezing the micro wire chips for dehydration. Through the setting of the drain pipe 560, the motor 710 can be started after the residual water in the water storage cavity 510 is completely drained. In this way, the micro wire chips will not be soaked in water, squeezing water is easier, and there will be no problem of water flowing into the storage unit 100 when the sealing door 130 is pushed open by the puncturing part 221.

[0133] Furthermore, a valve plate 570 is arranged at the water outlet end position of the drain pipe 560. When the micro wire chip collecting device is filling with water, the valve plate 570 can block the water outlet end of the drain pipe 560 to ensure that the water in the water storage cavity 510 will not leak, and at the same time prevent the unfiltered water from directly entering the water storage cavity 510 through the drain pipe 560, causing the micro wire chips to be discharged with the water flow. After the water inlet stops, the valve plate 570 can open the water outlet end of the drain pipe 560, so that the residual water in the water storage cavity 510 is discharged along the drain pipe 560.

[0134] Specifically, a tubular structure formed by extending the water inlet 520 has an opening, and the water outlet end of the drain pipe 560 is inserted into the opening. The valve plate 570 is rotatably installed on the inner wall of the tubular structure at the water inlet 520, and the lower side of the valve plate 570 is rotatably connected to the inner wall of the tubular structure below the opening.

[0135] With the above structure, during the water inlet process, see Figure 8 , the water flow passes through the tubular structure at the water inlet 520 from bottom to top, and the valve plate 570 fits against the inner wall of the tubular structure under the impact of the water flow, thus blocking the water outlet end of the drain pipe 560. After the water inlet stops, see Figure 9 , the water pressure in the drain pipe 560 will push the valve plate 570 to turn downward to open the water outlet end of the drain pipe 560, so that the water in the water storage cavity 510 is discharged along the drain pipe 560.

[0136] More specifically, by setting a limiting structure on the valve plate 570 or at the water inlet 520, the rotatable angle of the valve plate 570 is controlled not to exceed 90°. That is to say, in the open state, the valve plate 570 can at most turn downward to the horizontal state. In this way, during the next water inlet, it can be ensured that the water flow impacts the lower surface of the valve plate 570, and then pushes it to block the water outlet end of the drain pipe 560.

[0137] When the micro wire debris collection device described in this embodiment is applied to a washing device, after each drainage operation of the washing device is completed, wait for a set duration and then start the motor 710. The set duration is at least not less than the duration required for the water in the water storage cavity 510 to drain from the highest water level along the drain pipe 560 to a level lower than the bottommost water level of the filter cylinder 370. In this way, it can be ensured that the motor 710 is started when there is no accumulated water in the filter cylinder 370, driving the rotating shaft 320 and the spiral blade 310 to rotate, squeezing the micro wire debris to dehydrate and sending it into the storage unit 100.

[0138] In this embodiment, by providing the drain pipe 560, the residual accumulated water in the water storage cavity 510 can be drained completely. On the one hand, it avoids the micro wire debris in the filter cylinder 370 being soaked in water, making it easier to squeeze and dehydrate the micro wire debris before it enters the storage unit 100. On the other hand, it also avoids water flowing into the storage unit 100 when the sealing door 130 is pushed open. The opening and closing of the water outlet end of the drain pipe 560 are controlled by the valve piece 570, and the valve piece 570 can automatically rotate under the impact of water flow, with a simple structure and easy to implement.

[0139] Embodiment Three

[0140] As Figure 10 shown, the difference between this embodiment and the above Embodiment One is that: the axis of the filter cylinder 370 extends along the vertical direction.

[0141] Specifically, in this embodiment, the filter cylinder 370 extends vertically, and its upper end is connected to the storage unit 100. The water storage shell 550 is correspondingly arranged to extend up and down. The first opening 541 is provided on the upper end wall of the water storage shell 550 for the upper end of the filter cylinder 370 to pass through and connect to the storage unit 100. The second opening 542 is provided on the lower end wall of the water storage shell 550, so as to realize the transmission connection between the rotating shaft 320 and the transmission unit 600 below the water storage shell 550.

[0142] In this embodiment, the specific structures of the transmission unit 600 and the driving unit 700 are the same as those in Embodiment One, only the installation angle is rotated by 90° as a whole.

[0143] Furthermore, in this embodiment, the water outlet 530 is arranged in the area near the lower end of the water storage shell 550. Preferably, the lower side of the water outlet 530 is flush with the inner surface of the lower end wall of the water storage shell 550. In this way, it is beneficial for the water entering the micro wire debris collection device to be fully discharged through the water outlet 530, avoiding residual accumulated water in the water storage cavity 510.

[0144] Similar to the first embodiment above, there is a certain distance between the two ends of the filtering part 380 and the two ends of the filtering cylinder 370 respectively, so as to ensure that during the up and down movement of the rotating shaft 320, the filtering part 380 is always in the area between the compression hopper 220 and the sealing gasket 340. The opening structure 371 on the filtering cylinder 370 is arranged in the area near the upper end of the filtering part 380, and the water entering the inside of the filtering cylinder 370 flows from top to bottom, which can make more full use of the covering area of the filtering part 380.

[0145] As a preferred embodiment, in the circumferential direction of the water storage shell 550, the water inlet 520 and the water outlet 530 are arranged at opposite positions, further ensuring that the filtering part 380 arranged circumferentially around the filtering cylinder 370 can be fully utilized.

[0146] In a further solution of this embodiment, the storage unit 100 first bends downward from the upper end of the filtering cylinder 370 and then continues to extend downward. In this way, when the fine wire scraps entering the storage unit 100 gradually increase, some of the fine wire scraps can fall to the lower end of the downward extending part of the storage unit 100, rather than all accumulating at the inlet of the storage unit 100.

[0147] Specifically, the storage cylinder 110 of the storage unit 100 is arranged parallel to the filtering cylinder 370 on the outside of the water storage shell 550, and the upper end of the storage cylinder 110 is at a height close to the upper end of the filtering cylinder 370. The rigid section of the storage unit 100 is connected to the upper end of the filtering cylinder 370, and the connecting part 120 extends along an arc from the rigid section to be connected to the upper end of the storage cylinder 110. After the fine wire scraps enter the storage unit 100, as the amount of the fine wire scraps gradually increases, some of the fine wire scraps can cross the lower side of the connecting part 120 and fall to the bottom of the storage cylinder 110.

[0148] When the fine wire scrap collecting device described in this embodiment is applied to a washing device, since the compression hopper 220 is located in the upper end area of the filtering cylinder 370, by controlling the drainage flow rate of the washing device within a certain range, it can be ensured that the water level in the filtering cylinder 370 never exceeds the lower end of the compression hopper 220. In this way, it can be realized that while the washing device is draining water, the fine wire scrap collecting device is cleaning the filtering cylinder 370 at the same time, sending the filtered fine wire scraps into the storage unit 100, and there will be no problem of water flow entering the storage unit 100, which is beneficial to keeping the highest filtering efficiency of the filtering part 380 all the time.

[0149] Specifically, the following control method is adopted in this embodiment to separate the fine wire scraps from the drainage water flow of the washing device and collect and store them.

[0150] The washing device performs a drainage operation, and a drainage water flow is introduced into the micro lint collection device for filtration. During the drainage operation of the washing device, the control shaft 320 is rotated and moved along the axis towards the sealing assembly, driving the piercing portion 221 to move and push open the sealing assembly. The control shaft 320 continues to rotate, and the spiral blade 310 rotates with the control shaft 320, conveying the micro lint in the filter cylinder 370 upwards, and sending it into the storage unit 100 through the pushed open sealing assembly.

[0151] Specifically, each time the washing device starts to perform the drainage operation, or after the drainage operation has been performed for a certain period of time, the control motor 710 is started, and the control shaft 320 is driven to rotate in the first direction through the transmission of the transmission unit 600. While the control shaft 320 rotates, it also moves upwards, pushing the compression hopper 220 to rise, so that the piercing portion 221 penetrates the sealing door 130. The motor 710 continues to operate, and the control shaft 320 no longer moves upwards, but can continue to rotate, and then continuously sends the micro lint inside the filter cylinder 370 into the storage unit 100 through the spiral blade 310.

[0152] In this embodiment, the filter cylinder 370 is vertically installed, and the compression hopper 220 is located at the upper end of the filter cylinder 370, greatly reducing the probability that the residual lint inside is re-wetted by water. By controlling the drainage flow rate of the washing device, it is possible to clean the micro lint while draining water, ensuring that the filtering portion 380 always maintains the highest filtering efficiency, which is conducive to ensuring that the drainage efficiency of the washing device will not decrease due to the blockage of the filtering portion 380.
