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 washing equipment. Background Art

[0002] Micro lint is the lint fiber debris that rubs off between clothes, or between clothes and the washing machine during the clothes 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 wide popularity of chemical fiber clothes at present, the micro lint generated during their washing process is also called microplastics, which can enter the human blood through the food chain.

[0003] At present, 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 intensive research is underway. 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] For the existing devices applied to washing equipment for filtering micro lint, since it is not allowed to discharge micro lint into the environment through the sewer, it is often necessary for users to manually collect it after filtration and then perform post-treatment. Generally, since micro lint and coarser and larger lint with larger sizes are filtered out together when filtering micro lint, the amount of lint filtered is relatively large, and users need to frequently manually clean the filtered lint, for example, manually clean the filtered lint once every one or two months. Also, because the filtered lint is in a humid environment, it is very easy to mildew and generate odors, resulting in a very poor experience for users during the process of cleaning micro lint. Therefore, the device that requires users to frequently perform manual cleaning leads to a bad user experience.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] 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 washing equipment, which can automatically clean the micro lint blocking the filter element, improve the filtering and drainage efficiency, thereby extending the service life of the filter element and reducing the replacement frequency of users.

[0007] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is:

[0008] A micro lint collecting device, comprising:

[0009] A housing, provided with a water inlet and a water outlet;

[0010] The filter element is suspended inside the housing and filters the water entering the housing.

[0011] The vibrating member is in contact with the filter element and is used to drive the filter element to vibrate.

[0012] Further, the water inlet is provided on the top wall of the housing, and the water outlet is provided on the bottom wall of the housing; a suspension member is provided inside the top wall of the housing, and the suspension member is connected to the top surface of the filter element.

[0013] Further, the filter element includes a filtering main body and an end cap. The filtering main body is a cylindrical structure with a certain wall thickness and extending vertically. The outer peripheral wall and the bottom wall of the filtering main body are spaced from the inner wall of the housing to form a water collecting cavity communicating with the water outlet.

[0014] The end cap is provided on the top of the filtering main body, and the water inlet communicates with the central cavity of the filtering main body through the end cap; the suspension member is connected to the end cap.

[0015] Further, the upper end of the central cavity of the filtering main body is open, and a water inlet pipe communicating with the central cavity is provided on the end cap. The water inlet pipe is communicated with the water inlet on the housing through a flexible connecting pipe.

[0016] Preferably, the connecting pipe is a corrugated pipe.

[0017] Further, the filtering main body includes:

[0018] The first filter body is a cylindrical structure with a certain wall thickness, and a central cavity of the filtering main body is formed at the center of the first filter body.

[0019] The second filter body is arranged outside the first filter body and is a cylindrical structure with a certain wall thickness.

[0020] The fine mesh cylinder is arranged outside the second filter body and has a plurality of mesh holes for filtering fine wire scraps. The fine mesh cylinder is spaced from the outer wall of the second filter body to form a fine wire scrap collecting cavity outside the second filter body.

[0021] Wherein, the filtering accuracy of the fine mesh cylinder is higher than that of the second filter body, and the filtering accuracy of the second filter body is not lower than that of the first filter body.

[0022] Preferably, the vibrating member is arranged on the end cap or the fine mesh cylinder.

[0023] Further, an annular wall extends downward from the outer periphery of the end cap, and the upper end of the fine mesh cylinder is connected to the annular wall.

[0024] On the lower side surface of the end cap, a limiting ring is provided inside the annular wall, and the upper end of the second filter body is limited inside the limiting ring.

[0025] Further, the upper end of the second filter body is open and the lower end is closed; a first mesh cylinder with a water-permeable structure is disposed around the outside of the second filter body, and the micro wire debris collecting cavity is formed between the first mesh cylinder and the fine mesh cylinder.

[0026] Further, a second mesh cylinder with a water-permeable structure is disposed around the inside of the first filter body, and a third mesh cylinder with a water-permeable structure is disposed around the outside of the first filter body.

[0027] Further, a positioning portion is formed by partial upward protrusion of the bottom wall of the fine mesh cylinder, and the bottom of the second filter body has a concave structure corresponding to the positioning portion, and the positioning portion and the concave structure are in limiting cooperation.

[0028] Further, the housing includes a housing with an upper end open and the water outlet provided at the bottom, and an upper cover provided at the upper end opening of the housing and provided with the water inlet;

[0029] Preferably, the peripheral side wall of the housing is jointly formed by splicing the upper cover and the housing. When the filter element is suspended inside the housing, the height where the end cap is located is close to the connection between the upper cover and the housing.

[0030] A washing device, the drain pipe of the washing device is connected to the micro wire debris collecting device described above.

[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, the vibrating member can drive the filter element to vibrate, so that the micro wire debris stuck on the surface of the filter element is loosened and detached, increasing the drainage efficiency and filtering effect of the filter element. The filter element is suspended inside the housing, which can amplify the vibration effect, so as to improve the vibration efficiency with a smaller vibration power and make the effect of loosening and detaching the micro wire debris under the vibration better. In this way, the service life of the filter element is greatly extended, the frequency of the user replacing or cleaning the filter element can be reduced, and the user experience is improved.

[0033] In the present invention, the first filter body, the second filter body and the fine filter screen form a step-by-step filtering structure. Coarse wire debris is intercepted by the first filter body, the second filter body can filter smaller wire debris and part of the micro wire debris, and the fine mesh cylinder mainly intercepts the micro wire debris. Due to the three-dimensional space structure of the first filter body and the second filter body, a larger amount of wire debris can be accommodated inside, and the micro wire debris attached to the fine mesh cylinder can be loosened and detached under the action of the vibrating member and finally collected at the bottom of the micro wire debris collecting cavity, further reducing the frequency of the user cleaning and replacing.

[0034] In the present invention, the provision of the limiting ring ensures that there is a gap between the outer walls of the fine mesh cylinder and the second filter body, so that a micro wire debris collection cavity can be formed, avoiding the blockage caused by the attachment of micro wire debris to the fine mesh cylinder. The cooperation between the positioning portion on the fine mesh cylinder and the pit structure at the bottom of the second filter body is conducive to achieving the accurate positioning of the second filter body in the fine mesh cylinder.

Detailed Embodiments

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with 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.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" 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.

[0047] As Figures 1 to 3 shown, an embodiment of the present invention provides a micro lint collection device, which can be used to filter the washing water discharged by a washing device, filter out the micro lint that cannot be directly discharged from the water, so that the drainage of the washing device meets the discharge standards. An embodiment of the present invention also provides a washing device, and the drain pipe for the washing device to drain water outward is connected to the micro lint collection device, so that the micro lint collection device can be used to filter the discharged washing water.

[0048] In this embodiment, the washing device can be an electrical appliance with a clothing washing function such as a washing machine, a washer-dryer, a care machine, etc.

[0049] Specifically, in an embodiment of the present invention, the micro lint collection device can be externally applied to a washing device, including a housing 100 and a filter element 200 disposed inside the housing 100. Among them, a water inlet 102 and a water outlet 101 are provided on the housing 100. The washing water discharged by the washing device enters through the water inlet 102, is filtered through the filter element 200, and the filtered water is discharged through the water outlet 101.

[0050] As a specific embodiment, the outer shell 100 is a columnar structure with a hollow interior. The water inlet 102 is provided on the top wall of the outer shell 100, and the water outlet 101 is provided on the bottom wall of the outer shell 100.

[0051] In a more specific structure, the outer shell 100 includes a housing 110 and an upper cover 120, which are detachably connected, enabling the user to clean or replace the filter element 200 inside the outer shell 100. The housing 110 and the upper cover 120 can be connected by threads or connected by a hinge and provided with a buckle for fixation.

[0052] As a detailed structure, the housing 110 is a cylindrical structure with an open upper end and a bottom wall at the lower end. The water outlet 101 is provided at the center of the bottom wall of the housing 110. A water outlet joint 111 extends downward from the outer periphery of the water outlet 101 for connecting to a discharge pipe (not shown in the figure). The discharge pipe can be connected to a floor drain or other drainage facilities in the user's home to drain the washing water filtered by the micro lint collection device.

[0053] More specifically, the discharge pipe is a flexible pipe, and the water outlet joint 111 is a rigid pipe with a first rib provided on its outer peripheral wall, so that the discharge pipe can be firmly installed. On the other hand, a U-shaped elbow structure can be formed in a part of the discharge pipe to store water at the elbow structure, thereby achieving the sealing of the outside of the water outlet 101 of the micro lint collection device.

[0054] The upper cover 120 is buckled at the open upper end of the housing 110, and the peripheral side wall of the outer shell 100 is jointly formed by the upper cover 120 and the housing 110. The water inlet 102 is provided at the center of the upper cover 120, and a water inlet joint 121 is provided at the water inlet 102. The water inlet joint 121 extends upward at least from the top wall of the outer shell 100 for connecting to the drain pipe of the washing equipment for discharging water outward. In this way, when the washing equipment discharges water, the washing water discharged along the drain pipe enters the micro lint collection device through the water inlet joint 121 and the water inlet 102. After being filtered by the filter element 200, the micro lint in the washing water is collected, and the water meeting the discharge requirements can be sent into the discharge pipe through the water outlet 101 and the water outlet joint 111 for discharge.

[0055] More specifically, the entire water inlet joint 121 is a rigid pipe, which can be fixedly connected to the upper cover 120 or integrally formed. A second rib is provided on the outer peripheral wall of the part of the water inlet joint 121 located outside the outer shell 100 to facilitate the firm connection of the drain pipe of the washing equipment. Similar to the above-mentioned discharge pipe, the drain pipe can also be provided with a U-shaped elbow structure locally and then connected to the water inlet joint 121, so as to store water at the elbow structure and isolate the inside of the micro lint collection device from the outside. In this way, a relatively sealed environment can be formed inside the micro lint collection device. Especially when the lint collected inside becomes moldy, there will be no problem of odor leakage, and the user experience is better.

[0056] However, the washing water carries both micro lint and coarser, larger lint of a larger size. These coarser, larger lint are collected in the micro lint collection device together with the micro lint. As the usage time increases, the filter element 200 will gradually be blocked by lint, resulting in a decrease in the rate of the washing water passing through the filter element 200, and further affecting the drainage efficiency of the washing device. Although the user can manually clean or replace the filter element 200, the overly frequent cleaning or replacement operations are very inconvenient, resulting in a poor user experience.

[0057] For this reason, the micro lint collection device of this embodiment further includes a vibrating member 300, so as to drive the filter element 200 to vibrate through the vibrating member 300, and reduce the degree of blockage of the filter element 200 by lint.

[0058] Specifically, the filter element 200 is suspended inside the housing 100, and the vibrating member 300 is in contact with the filter element 200. After the vibrating member 300 is started, it can drive the filter element 200 to vibrate with the vibrating member 300. And because the filter element 200 is suspended in the housing 100 and does not directly contact the inner surface of the housing 100, it has a large degree of freedom of movement, which can amplify the vibration effect, so as to achieve the effect of improving the vibration efficiency with a smaller vibration power.

[0059] Through the above solution, the micro lint attached to the filter element 200, especially the micro lint firmly attached to the surface of the filter element 200, can be loosened and detached under the vibration. During the use of the micro lint collection device, by starting the vibrating member 300, the filtering ability of the filter element 200 can be restored to a certain extent, thereby increasing the drainage efficiency and filtering effect of the filter element 200. In this way, only when the inside of the filter element 200 is completely filled with lint does the user need to manually clean or replace it, which can extend the service life of the filter element 200.

[0060] In a further solution, a suspension member 400 is connected to the inner side of the top wall of the housing 100, that is, the inner side of the upper cover 120. The suspension member 400 is connected to the top surface of the filter element 200, so as to suspend the filter element 200 inside the housing 100. The suspension member 400 is a flexible structure, so as to improve the vibration efficiency.

[0061] As a specific implementation manner, the suspension member 400 is a chain-like object. Among them, a first connection ring is arranged on the inner side of the upper cover 120, a second connection ring is arranged on the top surface of the filter element 200, the upper end of the suspension member 400 is connected to the first connection ring, and the lower end is connected to the second connection ring.

[0062] It can be understood that the structure for connecting the suspension member is not limited to the connection ring described above, and other connection structures can also be used.

[0063] In a preferred embodiment, the suspension member can be a strip-shaped object made of materials such as ropes or rubber. More preferably, the suspension member is a rope-like structure formed by wrapping a steel wire with rubber.

[0064] In a further aspect of this embodiment, the filter element 200 includes a filter main body for filtering the washing water. The filter main body is a cylindrical structure with a certain wall thickness and extending vertically. The outer peripheral wall and the bottom wall of the filter main body are spaced apart from the inner wall of the housing 100 to form a water collecting chamber 112 communicating with the water outlet 101. The central cavity of the filter main body communicates with the water inlet 102. The washing water to be filtered enters the central cavity of the filter main body through the water inlet 102, penetrates outward through the filter main body for filtration, and the washing water meeting the discharge requirements is collected in the water collecting chamber 112 and flows out through the water outlet 101.

[0065] Furthermore, the filter element 200 further includes an end cap 250 provided at the top of the filter main body. The water inlet 102 communicates with the central cavity of the filter main body through the end cap 250, and the lower end of the suspension member 400 is connected to the end cap 250.

[0066] In a specific structure, both the housing 100 and the filter element 200 are cylindrical and extend vertically. The water inlet 102 is provided at the center of the top wall of the housing 100. The center of the end cap 250 has a water inlet pipe 251. The water inlet 102 communicates with the central cavity of the filter main body through the water inlet pipe 251. A plurality of suspension members 400 are arranged around the central axis of the filter element 200, and the plurality of suspension members 400 are evenly distributed in the circumferential direction, thereby improving the stability of the filter element 200 in the housing 100.

[0067] Furthermore, a flexible connecting pipe 500 is provided at the upper end of the water inlet pipe 251 and communicates with the water inlet 102 on the housing 100 through the connecting pipe 500. In a specific embodiment, a corrugated pipe made of rubber can be used as the connecting pipe 500.

[0068] When the vibrating member 300 is started and drives the filter element 200 to vibrate, the connecting pipe 500 can deform itself to adapt to the vibration of the filter element 200, avoiding loosening of the connections at both ends of the connecting pipe 500 and reducing the vibration amplitude.

[0069] As a specific embodiment, the upper end of the central cavity of the filter main body is open, and the water inlet pipe 251 extends vertically and has openings at both ends, so as to communicate with the central cavity of the filter main body.

[0070] More specifically, the upper end of the water inlet pipe 251 is higher than the upper surface of the end cap 250, and the lower end of the connecting pipe 500 is sleeved on the water inlet pipe 251. The lower end of the water inlet joint 121 is lower than the lower surface of the top wall of the housing 100, so that the upper end of the connecting pipe 500 can be sleeved on the lower end of the water inlet joint 121.

[0071] In a detailed structure, the upper end of the water inlet pipe 251 is higher than the upper surface of the end cover 250 and is used to connect the connecting pipe 500. The lower end of the water inlet pipe 251 extends into the central cavity of the filtering main body.

[0072] In a further solution of this embodiment, the filtering main body includes a filter body and a fine mesh cylinder 230. Among them, the filter body is a cylindrical structure with a certain wall thickness, and a central cavity of the filtering main body is formed at its center as a large lint collection cavity 2121. The fine mesh cylinder 230 is arranged outside the filter body and is spaced from the outer wall of the filter body. The fine mesh cylinder 230 has a number of mesh holes for filtering micro lint, and a micro lint collection cavity 232 is formed between the fine mesh cylinder 230 and the filter body.

[0073] In the above solution, the filter body has a porous structure and a relatively large wall thickness, which can achieve three-dimensional space filtration and accommodate lint in the internal space. The fine mesh cylinder 230 is arranged on the outermost side. After the washing water passes through the filter body, large-sized lint has been intercepted by the filter body. The fine mesh cylinder 230 mainly intercepts micro lint and collects the micro lint in the micro lint collection cavity 232.

[0074] As a specific implementation manner, the fine mesh cylinder 230 is a cylindrical structure with an open upper end and a closed lower end, and the upper end of the fine mesh cylinder 230 is connected to the end cover 250.

[0075] For the micro lint collection device with the above structure, after filtering for a period of time, as Figure 2 shown, a micro lint film 600 formed by the accumulation of micro lint will adhere to the inner side of the fine mesh cylinder 230. This micro lint film 600 will block the passage of the washing water, thereby affecting the filtration efficiency.

[0076] After the vibrating member 300 is started, the micro lint film 600 adsorbed on the inner side of the fine mesh cylinder 230 falls off under the vibration and drops to the bottom of the micro lint collection cavity 232, forming a micro lint layer 700 as shown in Figure 3 . In this way, most of the area of the fine mesh cylinder 230 can be exposed, improving the filtration efficiency of the filter element 200. Only when the micro lint collection cavity 232 is filled with micro lint and the vibrating member 300 continues to operate and cannot release the space of the micro lint collection cavity 232, does the user need to replace or clean the filter element 200, thereby greatly extending the service life of the filter element 200.

[0077] In a specific implementation manner of this embodiment, the vibrating member 300 is disposed on the end cover 250, for example, on the upper side of the end cover 250 and in contact with the end cover 250. The end cover 250 can be made of a rigid plastic structure or a rust-proof metal structure, such as galvanized steel sheet or stainless steel, which can improve the rigidity while ensuring no rusting, and no vibration energy will be wasted when the vibrating member 300 vibrates.

[0078] In a specific solution, the fine mesh cylinder 230 is formed by processing an ultra-thin stainless steel sheet with certain elasticity through laser drilling. The laser drilling can form a number of mesh holes on the stainless steel sheet for filtering micro wire chips. The elastic property of the fine mesh cylinder 230 is beneficial to amplifying the vibration effect, so that the attached micro wire chips can be more fully detached or passed through.

[0079] In another specific solution, the fine mesh cylinder 230 can have a Figure 4 skeleton 233 as shown. The skeleton 233 is an upper-end open cylinder with a hollow structure, and a stainless steel mesh with appropriate-sized mesh holes is surrounded on the skeleton 233. This structure can achieve a good effect when the vibrating member 300 vibrates.

[0080] In another specific implementation manner of this embodiment, the vibrating member can also be directly disposed on the fine mesh cylinder, which can drive the fine mesh cylinder to generate a larger vibration amplitude, so as to more fully peel off the attached micro wire chips.

[0081] As a specific implementation manner, the vibrating member 300 can be a motor equipped with an eccentric wheel, which can generate periodic vibration when rotating.

[0082] As a preferred implementation manner, the vibrating member 300 has a piezoelectric material. After it is connected to a high-frequency oscillation circuit, the inverse piezoelectric effect will occur, causing the piezoelectric material to generate periodic expansion and contraction, thereby generating high-frequency vibration.

[0083] When the vibrating member 300 starts to generate high-frequency vibration, it can drive the fine mesh cylinder 230 to generate high-frequency vibration. Furthermore, the wire chips located in the mesh holes of the fine mesh cylinder 230 and attached to the wall of the fine mesh cylinder 230 will also vibrate and displace under the action of vibration. The fine mesh cylinder 230 is a thin-wall structure. When the wire chips stuck in the mesh holes move out a little, they will enter the water collecting cavity 112 and be discharged together with the washing water. When they move in a little, they will fall into the micro wire chip collecting cavity 232 and be collected, so that the mesh holes on the fine mesh cylinder 230 can quickly return to a smooth state.

[0084] It can be understood that the wire chips that can pass through the mesh holes of the fine mesh cylinder 230 and enter the water collecting cavity 112 indicate that their diameters are smaller than the aperture of the mesh holes. Such-sized wire chips are wire chips that are legally allowed to be discharged and will not cause the washing water discharge to fail to meet the standards.

[0085] In a specific structure, a through hole is provided on the upper cover 120, and a power cord connected to the vibrating member 300 and used for power supply passes through the through hole and out of the upper cover 120. A sealing member 122 is filled in the through hole for sealing. In this way, not only the power supply of the vibrating member 300 is ensured, but also the washing water will not seep out of the housing 100. The sealing member 122 is preferably in a frustum shape with a smaller diameter on the upper side and a larger diameter on the lower side. After installation, the internal air pressure or water pressure will make its sealing effect better.

[0086] In this embodiment, the vibrating member 300 can be started during the period when the fine mesh cylinder 230 is immersed in the washing water. At this time, the lint stuck in the mesh holes of the fine mesh cylinder 230 is immersed in the water and can be buoyed by the water, and is more likely to fall off under the vibration.

[0087] For example, the vibrating member 300 can be intermittently started during the drainage process of the washing device, or the vibrating member 300 can be started to operate for a period of time when the drainage of the washing device is nearly completed.

[0088] Of course, the vibrating member 300 can also be continuously turned on throughout the process of filtering the washing water discharged from the washing device through the micro lint collecting device, reducing the adhesion of lint on the fine mesh cylinder 230, thereby improving the drainage efficiency.

[0089] In another solution, the vibrating member 300 can also be started to operate for a period of time before each washing program of the washing device. Generally, at this time, at least dozens of hours have passed since the previous drainage of the washing device. The lint stuck on the fine mesh cylinder 230 has a significantly reduced water content and a significantly shrunk volume after a long time of evaporation, and is more likely to fall off from the mesh holes under the vibration.

[0090] In a further solution of this embodiment, the filter body includes a first filter body 210 and a second filter body 220, both of which are cylindrical structures with a certain wall thickness. Among them, a large lint collecting cavity 2121 is formed at the center of the first filter body 210. The second filter body 220 is coaxially arranged outside the first filter body 210, and its outer wall is spaced from the fine mesh cylinder 230, thereby forming the micro lint collecting cavity 232 on the outside.

[0091] The filtering accuracy of the fine mesh cylinder 230 is higher than that of the second filter body 220, and the filtering accuracy of the second filter body 220 is higher than that of the first filter body 210.

[0092] With the above solution, the filter element 200 forms a step-by-step filtering structure. After the washing water to be filtered enters the large lint collecting cavity 2121, it penetrates from the inside to the outside and sequentially passes through the first filter body 210, the second filter body 220, and the fine mesh cylinder 230, and the lint in the water can be filtered step by step and finally collected in the water collecting cavity 112 outside the fine mesh cylinder 230 and discharged from the water outlet 101.

[0093] The first filter body 210 and the second filter body 220 are three-dimensional space structures with holes inside, which can accommodate more lint and are not easily blocked by lint. A fine mesh cylinder 230 is arranged on the outermost side, so that the washing water passing through the fine mesh cylinder 230 meets the requirements of micro-lint filtration. The fine mesh cylinder 230 has the greatest resistance to water, and being arranged on the periphery can also increase the filtration area and ensure the water outlet efficiency.

[0094] In addition, in the process of step-by-step filtration, relatively thick lint can be collected inside the first filter body 210, the second filter body 220 collects smaller lint, and the fine mesh cylinder 230 mainly intercepts micro-lint. When the holes inside the first filter body 210 are filled with thick lint, the continuously entering thick lint will gather in the large lint collection cavity 2121. Only when the large lint collection cavity 2121 and the first filter body 210 are filled with thick lint, the second filter body 220 is filled with ordinary small lint, and the micro-lint collection cavity 232 is filled with micro-lint, will the water outlet of the entire filter element 200 be blocked, and the user needs to manually clean or replace it.

[0095] Therefore, in this embodiment, the step-by-step filtration structure composed of the first filter body 210, the second filter body 220 and the fine mesh cylinder 230 can further extend the service life of the filter element 200.

[0096] In this embodiment, since the filter element 200 has a long service life, the usage cost is spread out. When the service life of the filter element 200 expires, the user can replace the entire filter main body. Specifically, the user opens the upper cover 120. Since the filter element 200 is connected to the upper cover 120 through the suspension member 400, the user can hold the upper cover 120 and take out the filter element 200 from the housing 110. Then, the user can remove the fine mesh cylinder 230 from the end cover 250, and remove the first filter body 210 and the second filter body 220 inside the fine mesh cylinder 230 together and discard them. Then, install a new filter main body, and then place the filter element 200 with the replaced filter main body back into the housing 110.

[0097] In another solution, the fine mesh cylinder 230 can be reused, and when the user cleans the filter element 200, only the first filter body 210 and the second filter body 220 inside are replaced, and the replacement cost is lower. Specifically, after the user holds the upper cover 120 and takes out the filter element 200 from the housing 110, the fine mesh cylinder 230 can be removed from the end cover 250 for cleaning, and the whole composed of the first filter body 210 and the second filter body 220 is directly discarded after being taken off. Then, first install a new filter body, which can be directly installed on the end cover 250 or installed in the cleaned fine mesh cylinder 230, and then reinstall the fine mesh cylinder 230 back on the end cover 250. Then, the filter element 200 can be placed back into the housing 110.

[0098] In another specific implementation of this embodiment, three or more concentric cylindrical filter bodies can be arranged outward from the large lint collection chamber. The filtration precision of each cylindrical filter body is different, and the filtration precision increases one by one from the inside to the outside.

[0099] In a further solution of this embodiment, the upper end of the second filter body 220 is open and the lower end is closed. A first mesh cylinder 221 with a water-permeable structure is arranged around the outside of the second filter body 220, and a micro lint collection chamber 232 is formed between the first mesh cylinder 221 and the fine mesh cylinder 230.

[0100] Furthermore, a second mesh cylinder 212 with a water-permeable structure is arranged around the inside of the first filter body 210, and a third mesh cylinder 211 with a water-permeable structure is arranged around the outside of the first filter body 210. In a specific structure, the first filter body 210 is a cylindrical structure with both ends open. Alternatively, in another specific structure, the first filter body can be similar to the second filter body and be arranged as a cylindrical shape with the upper end open and the lower end closed.

[0101] As a specific solution, the water-permeable structures on the above-mentioned first mesh cylinder 221, second mesh cylinder 212, and third mesh cylinder 211 are a number of water-permeable holes with relatively large sizes, and various sizes of lint carried in the washing water can basically pass through the water-permeable holes. In the above solution, the first mesh cylinder 221, second mesh cylinder 212, and third mesh cylinder 211 do not play a filtering role, but are only used to gather the first filter body 210 and the second filter body 220 and maintain their cylindrical structures.

[0102] It can be understood that when the user cleans the filter element 200, the first mesh cylinder 221, second mesh cylinder 212, and third mesh cylinder 211 are replaced together with the first filter body 210 and the second filter body 220.

[0103] In a specific implementation manner, both the first filter body 210 and the second filter body 220 are made of a block filled with loofah or a loofah-like structure. Among them, compared with the first filter body 210, the second filter body 220 is filled with blocks processed into smaller sizes, or the same filler but pressed more tightly.

[0104] During manufacturing, the second mesh cylinder 212 and the third mesh cylinder 211 can be pre-fixed at the lower end, and then the blocks used to form the first filter body 210 are filled between the second mesh cylinder 212 and the third mesh cylinder 211. The formed integral body of the first filter body 210, the second mesh cylinder 212, and the third mesh cylinder 211 is placed at the center of the first mesh cylinder 221, and then the blocks used to form the second filter body 220 are filled into the gap between the first mesh cylinder 221 and the third mesh cylinder 211.

[0105] When the block size of the second filter body 220 is smaller, it can be slightly compacted after filling. If the first filter body 210 and the second filter body 220 are formed by blocks of the same size respectively, it is necessary to compact more fully after the filling of the blocks of the second filter body 220 is completed.

[0106] The blocks of the loofah-like structure described above can be artificial blocks with a loofah-like shape and a three-dimensional maze structure with many large pores inside, or other plant fibers that can form a three-dimensional network structure with pores inside, or can be granular or powdery wood chips.

[0107] In a preferred embodiment of the present invention, loofahs are selected for the first filter body 210 and the second filter body 220. They are natural plant components, absorb carbon dioxide during production, can be naturally degraded after being discarded, and hardly produce carbon dioxide during degradation. They are suitable for use as directly replaceable filter consumables, which conforms to the environmental protection concept. On the other hand, the loofah itself has many relatively large pores, and in addition, the melon netting that forms a three-dimensional network is a rough structure, which is more likely to adsorb lint, so that the entire space inside the loofah can accommodate relatively large lint.

[0108] As a specific implementation manner, the volume of the first filter body 210 is larger than the volume of the second filter body 220. Specifically, the wall thickness of the first filter body 210 is greater than the wall thickness of the second filter body 220.

[0109] Among them, the first filter body 210 itself has many relatively large pores and can accommodate relatively large lint. Among the lint generated during the laundry process, the largest proportion is thick lint. The first filter body 210 occupies the largest volume in the overall filter body and can accommodate more thick lint without being blocked. In addition, the first filter body 210 is made of loofah, and the network structure forming the pores presents a rough texture after being soaked in water, and can also adsorb smaller lint or even micro-lint. The wall thickness of the second filter body 220 is smaller than the wall thickness of the first filter body 210, which is also beneficial to ensuring that the two have approximately the same drainage speed.

[0110] In an alternative embodiment of the present invention, the second filter body 220 can also be made of a sponge with high water permeability. Specifically, the sponge can be directly processed into the cylindrical structure of the second filter body 220, or a block sponge can be used to fill and form the second filter body 220.

[0111] It should be noted that the first filter body 210 and the second filter body 220 are made of relatively soft materials. When the vibrating member 300 generates high-frequency vibration, the lint already adsorbed inside the first filter body 210 and the second filter body 220 is hardly affected by the vibration and will not fall off and gather in the micro-lint collecting cavity 232, occupying the space of the micro-lint collecting cavity 232.

[0112] As a preferred embodiment, the first mesh cylinder 221, the second mesh cylinder 212, and the third mesh cylinder 211 respectively have a frame 260 as shown in Figure 5 and are made by wrapping a layer of plastic mesh with large holes around the frame 260, which is more economical. The frame 260 can be a hollow prismatic structure or a hollow cylindrical structure.

[0113] In a further solution of this embodiment, an annular wall 252 extends downward from the outer periphery of the end cap 250, and the upper end of the fine mesh cylinder 230 is connected to the annular wall 252. A limiting ring 240 is provided on the inner side of the annular wall 252 on the lower side surface of the end cap 250, and the upper end of the second filter body 220 is limited inside the limiting ring 240.

[0114] As a specific solution, the upper end of the fine mesh cylinder 230 is limited inside the annular wall 252, and the two are connected by threads. The limiting ring 240 is fixed on the lower side surface of the end cap 250, and the upper end of the first mesh cylinder 221 is clamped inside the limiting ring 240.

[0115] Through the setting of the limiting ring 240, the relative positions of the upper ends of the fine mesh cylinder 230 and the second filter body 220 can be fixed, thereby defining the space of the micro wire debris collection cavity 232.

[0116] In a further solution, a positioning portion 231 protrudes upward locally from the bottom wall of the fine mesh cylinder 230, and the bottom of the second filter body 220 has a concave structure 2211 corresponding to the positioning portion 231, and the positioning portion 231 and the concave structure 2211 are in limiting cooperation.

[0117] In a specific structure, a positioning portion 231 protrudes upward from the center of the bottom of the fine mesh cylinder 230, and a corresponding depression is formed on the outside of the fine mesh cylinder 230. The bottom of the first mesh cylinder 221 is recessed upward, so that after the second filter body 220 is filled, a concave structure 2211 is formed at the bottom. The positioning portion 231 and the concave structure 2211 are in limiting cooperation for the assembly positioning of the fine mesh cylinder 230 and the second filter body 220.

[0118] In a specific structure of this embodiment, when the filter element 200 is suspended inside the housing 100, the height where the end cap 250 is located is close to the junction of the upper cover 120 and the housing 110 on the side wall of the housing 100. Thus, when the user disassembles the upper cover 120 and the housing 110, it is easy to hold the end cap 250, and thus the fine mesh cylinder 230 can be removed from the end cap 250.

[0119] When the user uses the micro wire debris collection device provided in this embodiment, an operation process for cleaning the filter element 200 is specifically as follows:

[0120] When the service life of the filter element 200 expires and needs to be cleaned, the user can rotate the housing 110 or the upper cover 120 to disassemble the upper cover 120 from the housing 110. Then, holding the upper cover 120 by hand, the user can take out the filter element 200 as a whole from the housing 110. After that, when the user holds the end cover 250 and rotates the fine mesh cylinder 230 relative to it, the fine mesh cylinder 230 can be removed from the end cover 250. Since the fine wire chips are collected inside the fine mesh cylinder 230, the user will not come into contact with the said fine wire chips.

[0121] After that, the user can hold the end cover 250 and move the temporary assembly structure composed of the end cover 250 and the filter body above the trash can, making the filter body abut against one side of the trash can, so that the filter body can be separated from the end cover 250 by using the trash can. In this way, the user does not need to touch the wet or even moldy filter body with hands, and can complete the replacement more hygienically and quickly.

[0122] Then, the user can reinstall the new filter body onto the end cover 250, and then install the clean fine mesh cylinder 230 onto the end cover 250 to cover the outside of the filter body. Or, the user first installs the new filter body into the clean fine mesh cylinder 230, and realizes accurate positioning through the positioning part 231 and the pit structure 2211, and then installs the two together back onto the end cover 250.

[0123] The fine wire chip collection device provided by the embodiment of the present invention can filter the fine wire chips in the washing water, so that the drainage of the washing equipment applying the fine wire chip collection device meets the discharge standard. The said fine wire chip collection device can drive the suspension-mounted filter element 200 to vibrate by using the vibration part 300, so that the fine wire chips blocking the filter element 200, especially the fine wire chips attached to the inner side of the fine mesh cylinder 230 or stuck in the mesh holes of the fine mesh cylinder 230, become loose and detached, achieving the purpose of self-cleaning the mesh holes and greatly increasing the water permeability efficiency of the fine mesh cylinder 230. At the same time, the first filter body 210 and the second filter body 220 have a three-dimensional space structure. Compared with the scheme of a common multi-layer filter screen structure that needs to be replaced when the wire chips cover all the holes of the filter screen, the cleaning and replacement cycle of the filter element 200 is greatly extended.

[0124] On the other hand, the first filter body 210, the second filter body 220 and the fine mesh cylinder 230 form a step-by-step filtering structure, and the first filter body 210 and the second filter body 220 themselves can also filter part of the fine wire chips, so that fewer fine wire chips reach the fine mesh cylinder 230. Combined with the vibration cleaning of the fine mesh cylinder 230, the water permeability efficiency of the fine mesh cylinder 230 under long-term use is further increased.

[0125] By collecting and analyzing the micro lint in the washing water discharged by the washing equipment, various types of lint are obtained, especially the volume ratio of lint of different sizes. According to the volume ratio, the ratio between each space for accommodating lint in the micro lint collection device of this embodiment (including the large lint collection chamber 2121, the first filter 210, the second filter 220, and the micro lint collection chamber 232) is reasonably designed, so that each space reaches the standard for replacement simultaneously, which can better exert the potential of the filter element 200, extend the service life, and reduce the replacement cycle.

[0126] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above as equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the present invention.
