Description

Technical Field

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

[0002] Micro lint is the lint fiber debris that falls off during the clothing washing process due to the friction between clothes and between clothes and the washing machine. Larger micro lint has a size of several millimeters long. 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 popularization 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, the above-mentioned micro lint has been found in the 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] The existing devices used in washing equipment to filter micro lint, since they do not allow micro lint to be discharged into the environment through the sewer, usually require users to manually collect and then post-process after filtration. Generally, since micro lint and larger-sized thick and large lint are filtered out together when filtering micro lint, the amount of lint filtered is relatively large, and users often need to manually clean the filtered lint, such as manually cleaning the filtered lint once every one or two months. If the user forgets to clean, it is very likely that during the operation of the washing equipment, the filtration water outlet speed of the filtration device will decrease, affecting the drainage efficiency of the washing equipment. At this time, if the user waits until the current washing program is completed to clean, it may take a long time due to the reduced drainage efficiency. And if the user chooses to clean immediately, it will interrupt the operation of the current washing program, which may affect the washing effect.

[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 collection device, a washing equipment and a control method, which can achieve emergency drainage when the filter element is blocked, and avoid affecting the operation of the washing equipment.

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

[0008] The first object of the present invention is to provide a micro wire chip collecting device with emergency drainage ability when blocked, including:

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

[0010] A filter element disposed inside the housing, having a water inlet cavity communicating with the water inlet. At least part of the outer wall of the filter element is spaced from the inner wall of the housing to form a water collecting cavity communicating with the water outlet;

[0011] An overflow pipe, one end of which is located inside the water inlet cavity, near the top area of the water inlet cavity. The overflow pipe penetrates out from the area where the water inlet cavity communicates with the water inlet, and the other end communicates with the water collecting cavity or the water outlet.

[0012] Further, the water inlet is provided on the top wall of the housing. The filter element is a cylindrical structure with a certain wall thickness and extending vertically. The water inlet cavity is formed at the center of the filter element;

[0013] The upper end of the water inlet cavity is open. The overflow pipe sequentially passes through the upper open end of the water inlet cavity and the water inlet on the housing, and extends out of the housing.

[0014] Further, a water inlet joint extending upward from the top wall of the housing is provided at the water inlet. The overflow pipe passes through the side wall of the water inlet joint from above the water inlet;

[0015] Preferably, a monitoring component is provided on the part of the overflow pipe located outside the water inlet joint for monitoring whether there is water flow through the overflow pipe.

[0016] Further, the water outlet is provided on the bottom wall of the housing. A water outlet joint extending downward from the bottom wall of the housing is provided at the water outlet; the overflow pipe passes out from the side wall of the water inlet joint, extends outside the housing, and the other end communicates with the water outlet joint;

[0017] Preferably, the other end of the overflow pipe is connected to the side wall of the water outlet joint.

[0018] Further, the top surface of the filter element is spaced from the top wall of the housing. After passing out from the side wall of the water inlet joint, the overflow pipe bends downward and passes through the top wall of the housing to communicate with the water collecting cavity.

[0019] Further, it further includes a heating component for heating the filter element;

[0020] Preferably, the heating component includes an electromagnetic heating coil surrounding the filter element; the outermost side of the filter element has a fine mesh cylinder capable of filtering micro wire chips, and at least part of the fine mesh cylinder is made of a metal material capable of generating eddy currents in an alternating magnetic field.

[0021] Furthermore, the filter element is suspended inside the housing, and a vibrating member is in contact with the filter element; the inner side of the electromagnetic heating coil is spaced from the filter element;

[0022] Preferably, the filter element is suspended inside the housing.

[0023] The second object of the present invention is to provide a washing device capable of realizing a drainage and filtration function, and a drain pipe of the washing device is connected to the micro lint collecting device as described in the first object of the present invention.

[0024] The third object of the present invention is to provide a control method for a washing device that can realize drying and storing of micro lint and prevent the lint from mildewing. The washing device has a drain pump and a drain pipe communicated with the water outlet end of the drain pump. The drain pipe is connected to a micro lint collecting device; the micro lint collecting device includes a housing, a filter element for filtering washing water is arranged inside the housing, and a heating assembly for heating the filter element is also provided;

[0025] After the washing device finishes draining water, start the heating assembly to heat the filter element;

[0026] After the heating assembly continuously heats for a certain period of time, turn on the drain pump to pump air into the micro lint collecting device;

[0027] Preferably, the micro lint collecting device is the micro lint collecting device as described in the first object of the present invention.

[0028] Furthermore, after the washing device finishes draining water, execute a filter element drying program, including the following steps:

[0029] S1. Start the heating assembly, turn it off after continuously heating for a first preset duration;

[0030] S2. Turn on the drain pump, turn it off after continuously running for a second preset duration;

[0031] S3. If the start times of the heating assembly reach the set times, end the filter element drying program, otherwise return to step S1;

[0032] Preferably, after the washing device finishes draining water, wait for a third preset duration and then execute the filter element drying program;

[0033] Preferably, the first preset duration is less than the second preset duration;

[0034] Preferably, a vibrating member is in contact with the filter element, and after the filter element drying program ends, start the vibrating member to drive the filter element to vibrate.

[0035] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

[0036] In the present invention, when the filter element becomes blocked and the washing water in the water inlet chamber cannot pass through the filter element and be discharged, the continuously incoming washing water can be discharged along the overflow pipe, thereby achieving the purpose of emergency drainage. When the micro lint collection device is applied to a washing device to filter the discharged washing water, if the filtration and water discharge rate of the filter element significantly decreases, since emergency drainage can be carried out along the overflow pipe, the drainage rate of the washing device will not decrease, thereby avoiding the impact on the current operation of the washing device.

[0037] In the present invention, the overflow pipe is used to achieve the purpose of draining water around the filter element. Among them, the end of the overflow pipe for discharging water directly extends into the water collecting chamber communicated with the water outlet, or is connected to the water outlet joint, and can discharge the emergency discharged washing water and the filtered washing water along the same path. Only one pipeline for discharging washing water needs to be connected at the water outlet of the entire micro lint collection device, which is more convenient for installation. With the setting of the monitoring component, it is convenient for the user to timely know the occurrence of emergency drainage, so as to be able to clean the micro lint collection device more timely.

[0038] In the present invention, by setting a heating component to heat the filter element, the filter element and the collected micro lint can be dried and stored, avoiding the mildew or odor generation of the lint caused by a humid environment, and improving the user experience. The drainage pump is started after the filter element is heated for a period of time, and can discharge the moisture generated by heating as soon as possible, which is beneficial to drying the filter element faster. After the filter element is dried, it is vibrated to loosen and detach the micro lint stuck on the surface of the filter element, which helps to extend the service life of the filter element.

[0039] The following further describes in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Description of the Drawings

Specific Embodiments

[0049] 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.

[0050] 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 accompanying 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 cannot be construed as a limitation to the present invention.

[0051] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" 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 a direct connection or an indirect connection 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.

[0052] As Figures 1 to 6 shown, an embodiment of the present invention provides a micro lint collection device, a washing device applying the micro lint collection device, and a control method thereof. Among them, the washing device can be a washing machine, a washer-dryer, a care machine, or other washing devices with a clothes washing function.

[0053] Specifically, the micro lint collection device in the embodiment of the present invention includes 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 from the washing device enters through the water inlet 102, is filtered through the filter element 200, and the filtered water is discharged from the water outlet 101.

[0054] As a specific implementation manner, the micro lint collection device is externally connected to the washing device. That is, the washing device has a drain pipe extending to the outside of the casing for draining water outward. The drain pipe is connected to the micro lint collection device, specifically connected to a water inlet joint 121 provided at the water inlet 102.

[0055] In a further solution, a water outlet joint 111 is provided at the water outlet 101 for connecting 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.

[0056] In a specific implementation manner, the housing 100 is a columnar structure with a hollow interior. The water inlet 102 is provided on the top wall of the housing 100, and the water outlet 101 is provided on the bottom wall of the housing 100.

[0057] In a more specific structure, the housing 100 includes a housing body 110 and an upper cover 120, which are detachably connected. When the lint collected by the filter element 200 reaches a certain amount and the water discharge is blocked, the user can disassemble the housing 100 to clean or replace the internal filter element 200. The housing body 110 and the upper cover 120 can be connected by threads or can be connected by a hinge and provided with a buckle for fixation.

[0058] However, since users cannot directly observe the accumulation of micro-lint in the filter element 200, they may forget to clean it regularly, resulting in a serious drop in the filtration rate of the filter element 200. Alternatively, if the filter element 200 becomes severely clogged during the washing process of the washing machine, if the user chooses to clean the filter element 200 immediately, the washing process must be forced to stop, resulting in a poor user experience. If the washing process is not forced to stop, the user can only wait until the washing machine has finished its current run before cleaning the filter element 200. However, since the filtration rate of the filter element 200 is very low at this time, the drainage speed will be greatly reduced, which in turn leads to a significant decrease in washing efficiency.

[0059] On the other hand, since the filtered lint contains a large amount of water, the filter element 200 is in a highly humid state. The collected lint is stored in a humid and relatively closed environment for a long time, which is easy to mold or produce odor, affecting the user's experience.

[0060] Example 1

[0061] like Figure 1 As shown, this embodiment provides a micro-lint collecting device and a washing device using the micro-lint collecting device, which are used to solve the problem that the filtration rate of the above-mentioned filter element 200 decreases, which affects the drainage of the washing device.

[0062] In this embodiment, the micro-lint collection device includes a housing 100, which is provided with a water inlet 102 and a water outlet 101. A filter element 200 is disposed within the housing 100. The filter element 200 has a water inlet cavity 2122 communicating with the water inlet 102. The outer wall of the filter element 200 is at least partially spaced from the inner wall of the housing 100, forming a water collection cavity 112 communicating with the water outlet 101.

[0063] Washing water from the washing machine enters the water inlet chamber 2122 through the water inlet 102, then flows through the filter element 200 and collects in the water collection chamber 112. Lint in the water, especially micro-lint that is not allowed to be directly discharged, is intercepted by the filter element 200. The water that has been filtered by the filter element 200 and finally meets the discharge requirements is collected in the water collection chamber 112 and discharged through the water outlet 101.

[0064] The micro-lint collection device is also equipped with an overflow pipe 520 for emergency drainage. One end of the overflow pipe 520 connects to the water inlet chamber 2122, while the other end passes around the filter element 200 and connects to the water collection chamber 112 or the water outlet 101. If the filter element 200 becomes clogged, resulting in poor water flow, the wash water can be discharged directly through the overflow pipe 520, ensuring normal drainage of the washing machine.

[0065] In the specific solution of this embodiment, one end of the overflow pipe 520 is located inside the water inlet chamber 2122 and near the top region of the water inlet chamber 2122. Further, the overflow pipe 520 penetrates out from the region where the water inlet chamber 2122 communicates with the water inlet 102, and finally the other end communicates with the water collection chamber 112 or the water outlet 101.

[0066] With the above structure, only after the washing water fills the water inlet chamber 2122 and the washing water continues to be introduced into the water inlet chamber 2122, will the washing water enter the overflow pipe 520 and be discharged along the overflow pipe 520, avoiding the problem that the washing water carrying lint enters the overflow pipe 520 during normal drainage, resulting in filter failure.

[0067] At the same time, the outlet of the overflow pipe 520 communicates with the water collection chamber 112 or the water outlet 101, so that the emergency-discharged washing water and the filtered washing water are discharged from the micro lint collection device along the same path. Furthermore, only one discharge pipe for discharging the washing water needs to be connected at the water outlet 101 on the entire micro lint collection device, which is more convenient for installation.

[0068] In a further solution of this embodiment, the water inlet 102 is arranged on the top wall of the outer shell 100. The filter element 200 is a cylindrical structure with a certain wall thickness and extending vertically, and a water inlet chamber 2122 is formed at the center of the filter element 200. The upper end of the water inlet chamber 2122 is open. The overflow pipe 520 extends from its inlet end located inside the water inlet chamber 2122, passes through the upper open end of the water inlet chamber 2122 and the water inlet 102 on the outer shell 100 in sequence, and extends out of the outer shell 100.

[0069] As a specific implementation manner, a water inlet joint 121 extending upward from the top wall of the outer shell 100 is arranged at the water inlet 102 for connecting the drain pipe of the washing equipment. The overflow pipe 520 passes through the side wall of the water inlet joint 121 from above the water inlet 102, and thus extends out of the outer shell 100.

[0070] Further, the water outlet 101 is arranged on the bottom wall of the outer shell 100, and a water outlet joint 111 extending downward from the bottom wall of the outer shell 100 is arranged at the water outlet 101. After the overflow pipe 520 passes through the side wall of the water inlet joint 121, it extends outside the outer shell 100, and the other end communicates with the water outlet joint 111.

[0071] As a specific structure, the inlet end of the overflow pipe 520 is located inside the water inlet chamber 2122, slightly lower than the upper open end of the water inlet chamber 2122. The opening at the inlet end of the overflow pipe 520 is arranged downward to prevent the washing water from directly flowing into the overflow pipe 520 when it enters the water inlet chamber 2122.

[0072] The housing 100 is in the shape of a cylinder with a vertically extending axis. The downward projection of the water inlet 102 at least partially coincides with the upper open end of the water inlet chamber 2122. The overflow pipe 520 extends upward from its inlet end into the water inlet joint 121, passes through the side wall of the water inlet joint 121 and extends outward to the periphery, then extends downward from the outside of the circumferential side wall of the housing 100 to a position lower than the bottom wall of the housing 100, and then extends toward the water outlet joint 111. The outlet end of the overflow pipe 520 is connected to the side wall of the water outlet joint 111.

[0073] In this embodiment, with the above structure, the washing water carrying lint discharged along the overflow pipe 520 completely bypasses the water collecting chamber 112. That is to say, even in the case of emergency drainage, the lint will not enter the water collecting chamber 112, avoiding the problem that the residual lint in the water collecting chamber 112 is difficult to clean.

[0074] In a specific embodiment, the housing 100 is composed of a detachable upper cover 120 and a housing body 110. The overflow pipe 520 is made of a flexible hose, so as not to affect the opening and closing of the upper cover 120. The housing body 110 and the upper cover 120 can be connected by threads or can be connected by hinges and provided with buckles for fixation.

[0075] In a detailed structure of this embodiment, the housing body 110 is a cylindrical structure with an open upper end and a bottom wall at the lower end. The water outlet 101 is arranged at the center of the bottom wall of the housing body 110, and the water outlet joint 111 extends downward from the periphery of the water outlet 101. The water outlet joint 111 is a rigid pipe, and the discharge pipe connected thereto can be a flexible pipe. A first rib is arranged on the outer peripheral wall of the water outlet joint 111, so that the discharge pipe can be firmly installed.

[0076] It can be understood that the first rib is arranged at a position lower than the outlet end of the overflow pipe 520, so that the arrangement of the overflow pipe 520 does not affect the connection between the water outlet joint 111 and the discharge pipe.

[0077] The upper cover 120 is buckled at the open upper end of the housing body 110, and the circumferential side wall of the housing 100 is jointly formed by the upper cover 120 and the housing body 110. The water inlet 102 is arranged at the center of the upper cover 120. The water inlet joint 121 at least extends upward from the top wall of the housing 100. The whole water inlet joint 121 is a rigid pipe and can be fixedly connected to the upper cover 120 or integrally formed. A second rib is arranged on the outer peripheral wall of the part of the water inlet joint 121 located outside the housing 100, so as to facilitate the firm connection of the drain pipe of the washing device.

[0078] In this embodiment, both the drain pipe and the discharge pipe can be provided with a U-shaped elbow structure locally, and the water is stored by using this elbow structure, so as to isolate the inside of the micro lint collecting device from the outside and prevent the odor generated by lint storage from escaping.

[0079] In a further solution of this embodiment, a monitoring component 800 is provided at a portion of the overflow pipe 520 located outside the water inlet joint 121 for monitoring whether there is water flowing through the overflow pipe 520.

[0080] In a specific structure, the sensing end of the monitoring component 800 extends into the overflow pipe 520. When the filter element 200 becomes blocked, causing the washing water to enter the overflow pipe 520, the sensing end of the monitoring component 800 comes into contact with the washing water flowing along the overflow pipe 520, enabling the monitoring component 800 to generate a corresponding signal.

[0081] As a specific implementation, the monitoring component 800 is electrically connected to the main control board of the washing device and has a pair of electrodes extending into the overflow pipe 520. When the washing water flows through the overflow pipe 520, the electrodes come into contact with the water and conduct. When the main control board of the washing device obtains the signal that the electrodes are conducted, it indicates that the filtration efficiency of the filter element 200 is insufficient and its lifespan has expired. At this time, the main control board can control the washing device to emit a warning signal to remind the user to clean or replace the filter element 200.

[0082] In an existing solution, the service life of the filter element is judged by counting the running of the washing program. If the lint of the clothes washed by the user is less, there may be a situation where the user is reminded to clean the filter element before its actual service life expires, resulting in waste due to premature replacement by the user. Moreover, after replacing the filter element on some washing devices, the user also needs to manually reset the running times of the washing program to achieve re - counting. If the user forgets to reset, there will be a problem of repeated error alarms.

[0083] In the solution of this embodiment, the warning signal of the washing device is triggered by the washing water flowing through the overflow pipe 520, and the reliability of the warning is extremely high, and there is no need for the user to perform a manual reset operation.

[0084] In a specific solution of this embodiment, the filter element 200 includes an end cap 250 and a filtering main body. The filtering main body is used to filter the washing water and 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 100 to form a water collecting cavity 112 communicating with the water outlet 101.

[0085] The central cavity of the filtering main body forms a water inlet cavity 2122. The end cap 250 is arranged at the top of the filtering main body, and the water inlet 102 passes through the end cap 250 to communicate with the water inlet cavity 2122.

[0086] More specifically, both the housing 100 and the filter element 200 are cylindrical and extend vertically. The water inlet 102 is arranged at the center of the top wall of the housing 100, and there is a water inlet pipe 251 at the center of the end cap 250. The water inlet 102 communicates with the water inlet cavity 2122 through the water inlet pipe 251.

[0087] There is a certain gap between the inner surface of the top wall of the end cover 250 and the outer shell 100. A connecting pipe 510 is provided between the water inlet pipe 251 and the water inlet 102 to realize the conduction between the water inlet pipe 251 and the water inlet 102. The water inlet pipe 251 extends vertically and has openings at both ends. Its upper end is higher than the upper surface of the end cover 250, and the lower end of the connecting pipe 510 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 outer shell 100, so that the upper end of the connecting pipe 510 can be sleeved on the lower end of the water inlet joint 121.

[0088] As a specific implementation manner, the inlet end of the overflow pipe 520 is arranged lower than the lower end of the water inlet pipe 251. The overflow pipe 520 extends upward from its inlet end, passes through the water inlet pipe 251 and the connecting pipe 510 in sequence, extends into the water inlet joint 121, and passes out through the side wall of the water inlet joint 121.

[0089] The micro lint collection device provided in this embodiment is externally connected to a washing device for application. When the washing device drains water, the washing water mixed with lint enters the water inlet cavity 2122 at the center of the filtering main body, and then penetrates from the inside to the outside for filtration. The lint in the water is collected in the filter element 200, and the water meeting the discharge requirements is collected in the water collecting cavity 112 outside the filter element 200 and discharged from the water outlet 101.

[0090] Under normal circumstances, the washing water entering the water inlet cavity 2122 continuously penetrates outward, and the washing water will not enter the overflow pipe 520. When the filtration efficiency of the filter element 200 drops significantly and the water inlet rate is significantly greater than the water outlet rate, the liquid level height in the water inlet cavity 2122 will quickly rise to the height of contacting the overflow pipe 520. At this time, when the washing device continues to drain water outward, part of the washing water will enter the overflow pipe 520, and thus will be discharged along the overflow pipe 520 around the filter element 200, without affecting the drainage efficiency of the washing device.

[0091] When the washing water enters the overflow pipe 520, the monitoring component 800 contacts the washing water, and then can feedback a signal to the main control board of the washing device. The main control board will control the washing device to send out a warning signal to remind the user that the service life of the filter element 200 has expired and needs to be cleaned.

[0092] In the solution of this embodiment, when the service life of the filter element 200 expires but the user has no time to replace it, the micro lint collection device conducts emergency drainage without affecting the drainage efficiency of the washing device, so as to ensure that the washing device can normally complete the current washing program. At the same time, the micro lint collection device triggers the washing device to give a warning by monitoring the occurrence of emergency drainage, and can timely remind the user to clean or replace the filter element 200, so as to ensure that the washing water discharged by the washing device can be normally filtered when the washing device is used next time, and ensure that the drainage meets the discharge requirements. In addition, after the user cleans or replaces the filter element 200, there is no need to perform a manual reset operation for counting, which is more convenient to use.

[0093] Embodiment 2

[0094] As Figures 1 to 3 shown, this embodiment provides a micro lint collection device and a washing device applying the micro lint collection device, which are used to solve the problem that wet lint storage is prone to mildew or generate peculiar smell.

[0095] In this embodiment, the micro lint collection device includes a housing 100, an inlet 102 and an outlet 101 are arranged on the housing 100, and a filter element 200 is arranged inside the housing 100. The filter element 200 has a water inlet cavity 2122 communicated with the inlet 102, and at least part of the outer wall of the filter element 200 is spaced from the inner wall of the housing 100 to form a water collecting cavity 112 communicated with the outlet 101.

[0096] The washing water discharged from the washing device enters the water inlet cavity 2122 through the inlet 102, and converges to the water collecting cavity 112 through the filter element 200. The lint in the water, especially the micro lint that is not allowed to be directly discharged, can be intercepted by the filter element 200. The water that finally meets the discharge requirements after being filtered by the filter element 200 is collected in the water collecting cavity 112 and discharged through the outlet 101.

[0097] The micro lint collection device is also provided with a heating component 900 for heating the filter element 200. Specifically, after the last drainage of the current washing program of the washing device is completed, the heating component 900 can be started to heat and dry the filter element 200 and the collected lint, so as to realize the dry storage of the lint in the micro lint collection device and fundamentally solve the problems of mildew and peculiar smell of the lint and the filter element 200.

[0098] Furthermore, this embodiment can be a further limitation of the above Embodiment 1, that is, a heating component 900 is added on the basis of the micro lint collection device provided in the above Embodiment 1. Specifically, in this embodiment, the main part of the heating component 900 is arranged in the water collecting cavity 112.

[0099] However, it should be noted that in order to discharge the moisture generated by heating from the micro lint collection device, in this embodiment, no elbow structure is provided on the drain pipe of the washing device and the discharge pipe connected to the water outlet joint 111, which can make the gas flow more smoothly. And since the filter element 200 and the lint can be dried in this embodiment, there is no problem of lint mildew, and there is no need to isolate the inside of the micro lint collection device from the outside.

[0100] In addition, in this embodiment, the outlet end of the overflow pipe 520 is directly connected to the water outlet joint 111, and the washing water carrying lint will not enter the water collecting cavity 112, and thus will not come into contact with the heating component 900. In this way, the problem that lint adheres to the heating component 900 and is difficult to clean is avoided.

[0101] In a specific embodiment, the heating assembly 900 includes an electric heating wire, which is spirally arranged inside the housing 110, with both ends extending through the side walls of the housing 110 for connection to a power source. The filter element 200 is located inside the electric heating wire. When the heating assembly 900 is activated, the electric heating wire releases heat, heating and drying the filter element 200 and the collected lint.

[0102] As a preferred embodiment, the heating assembly 900 has an electromagnetic heating coil, which is spirally arranged around the filter element 200 in the water collection chamber 112. The filter element 200 has a portion made of metal material, and the metal material can generate eddy currents in an alternating magnetic field.

[0103] In one embodiment, the outermost portion of the filter element 200 includes a fine mesh cylinder 230 with a plurality of meshes that can filter out fine lint. As wash water flows outward from the central inlet chamber 2122, it ultimately passes through the fine mesh cylinder 230, intercepting fine lint that would otherwise be prevented from being discharged.

[0104] The fine mesh cylinder 230 is at least partially made of a metal material capable of generating eddy currents in an alternating magnetic field. When the heating assembly 900 is activated, high-frequency alternating current is applied to the electromagnetic heating coil, generating a high-frequency alternating magnetic field. This high-frequency alternating magnetic field excites the fine mesh cylinder 230, generating eddy currents and causing it to spontaneously heat, thereby drying the filter element 200 and the lint.

[0105] Through the above solution, filter element 200 can be heated in a remote manner, eliminating the need for heating component 900 to contact the outer surface of filter element 200. Since wash water is filtered from the inside out, the spacing between heating component 900 and the outer surface of filter element 200 can avoid obstructing the water outlet area, especially the mesh holes on fine mesh cylinder 230, thereby ensuring the water outlet efficiency of filter element 200. In addition, since heating component 900 itself does not generate heat, direct contact with housing 100 will not conduct heat outward, thus preventing damage to housing 100 or the risk of burns to the user.

[0106] In a preferred implementation of this embodiment, the fine mesh cylinder 230 is made of a stainless steel sheet after being punched by laser. The laser punching can form a plurality of mesh holes on the stainless steel sheet for filtering micro-wire chips.

[0107] In another optional embodiment, the fine mesh cylinder 230 may have Figure 4 The skeleton 233 is shown, and a stainless steel mesh with meshes of appropriate size is arranged around the skeleton 233.

[0108] It is understandable that other metal materials that can generate eddy current effects under the excitation of an alternating magnetic field can also be used as the material for the fine mesh cylinder 230. However, the fine mesh cylinder 230 made of stainless steel has a good rust prevention effect and is more suitable for the humid and high-temperature usage environment in this embodiment.

[0109] In a further solution of this embodiment, the micro wire chip collecting device is further provided with a vibrating member 300, which can drive the filter element 200 to vibrate through the vibrating member 300, so as to loosen and separate the wire chips blocking the mesh holes of the fine mesh cylinder 230, and reduce the degree of blockage of the fine mesh cylinder 230.

[0110] Specifically, the filter element 200 of this embodiment includes an end cap 250 and a filtering main body. The filtering main body further includes a filtering body and a fine mesh cylinder 230. Among them, the filtering body is a cylindrical structure with a certain wall thickness, and a water inlet cavity 2122 is formed at its center. The fine mesh cylinder 230 is arranged outside the filtering body and is spaced from the outer wall of the filtering body, and a micro wire chip collecting cavity 232 is formed between the fine mesh cylinder 230 and the filtering body.

[0111] The filtering body has a porous structure inside and a relatively large wall thickness, which can achieve three-dimensional space filtering and accommodate wire chips in the internal space. The fine mesh cylinder 230 is arranged on the outermost side. After the washing water passes through the filtering body, the large-sized wire chips have been intercepted by the filtering body. The fine mesh cylinder 230 mainly intercepts micro wire chips and collects the micro wire chips in the micro wire chip collecting cavity 232.

[0112] 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 cap 250.

[0113] For the micro wire chip collecting device with the above structure, after filtering for a period of time, as Figure 2 shown, a micro wire chip film 600 formed by the accumulation of micro wire chips will adhere to the inner side of the fine mesh cylinder 230. This micro wire chip film 600 will block the passage of the washing water, thereby affecting the filtering efficiency.

[0114] After the vibrating member 300 is started, the micro wire chip 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 wire chip collecting cavity 232, forming a micro wire chip 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 filtering efficiency of the filter element 200. Only when the micro wire chip collecting cavity 232 is filled with micro wire chips and the vibrating member 300 continues to operate and cannot release the space of the micro wire chip collecting 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.

[0115] In this embodiment, the vibrating member 300 can be started after the heating component 900 dries the filter element 200 and the lint. After the lint is dried, its volume will shrink significantly. At this time, starting the vibrating member 300 can more easily cause the lint to fall off from the mesh holes of the fine mesh cylinder 230 under the action of vibration. Through the cooperation of the heating component 900 and the vibrating member 300, the service life of the filter element 200 can be extended more effectively.

[0116] For the solution provided with the vibrating member 300, the fine mesh cylinder 230 can be processed from an ultra-thin stainless steel sheet with certain elasticity after laser drilling. Its elastic characteristics are beneficial to amplifying the vibration effect, so that the attached micro lint can be more fully detached or passed through.

[0117] Alternatively, the fine mesh cylinder 230 can also be formed by surrounding a stainless steel mesh with a framework 233 as shown in Figure 4 . The framework 233 is an upper-end open cylinder with a hollow structure. This structure can achieve a good effect when the vibrating member 300 vibrates.

[0118] In a further solution, the main part of the heating component 900 located in the water collecting cavity 112 is spaced from the filter element 200, so as to avoid affecting the vibration effect of the filter element 200.

[0119] As a specific structure, when the heating component 900 adopts an electromagnetic heating coil, the electromagnetic heating coil is spirally wound along the inner peripheral wall of the housing 110, and the inner side of the electromagnetic heating coil does not contact the outer peripheral wall of the filter element 200, that is, the fine mesh cylinder 230. The electromagnetic heating coil can realize non-contact heating and can achieve a high heating efficiency without contact. Both ends of the electromagnetic heating coil pass through the side wall of the housing 110 for connecting to a power supply.

[0120] It should be noted that the heating component 900 can be electrically connected to the main control board of the washing equipment, and the start and stop of the heating component 900 are controlled by the main control board of the washing equipment.

[0121] In a preferred solution of this embodiment, the filter element 200 is suspended inside the housing 100 and does not directly and rigidly contact the inner surface of the housing 100, having a large degree of freedom of movement. In this way, when the vibrating member 300 is started, the suspension structure helps to amplify the vibration effect, so as to achieve the effect of improving the vibration efficiency with a smaller vibration power.

[0122] As a specific implementation manner, 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 upper surface of the end cover 250, so as to suspend the filter element 200 inside the housing 100. The suspension member 400 is a flexible structure, which can improve the vibration efficiency.

[0123] In a specific structure, the suspension member 400 is a chain-like object. Among them, a first connection ring is provided inside the upper cover 120, a second connection ring is provided on the upper surface of the end cover 250, 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.

[0124] 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 adopted.

[0125] In a preferred embodiment, the suspension member can be a strip-shaped object made of materials such as ropes and rubbers. More preferably, the suspension member is a rope-like structure formed by rubber wrapping steel wires.

[0126] In a further solution, in this embodiment, a flexible connecting pipe 510 is used to connect the water inlet joint 121 and the water inlet pipe 251. In a specific embodiment, a corrugated pipe made of rubber material can be used as the connecting pipe 510.

[0127] When the vibrating member 300 is started and drives the filter element 200 to vibrate, the connecting pipe 510 itself can deform to adapt to the vibration of the filter element 200, avoiding the loosening of the connections at both ends of the connecting pipe 510 and reducing the vibration amplitude.

[0128] In a specific embodiment of this embodiment, the vibrating member 300 is arranged on the end cover 250, for example, arranged on the upper side of the end cover 250 and in contact with the end cover 250. The end cover 250 can adopt a rigid plastic structure, or can also adopt a non-rusting metal structure, such as galvanized steel plate or stainless steel, which improves the rigidity while ensuring non-rusting, and does not waste vibration energy when the vibrating member 300 vibrates.

[0129] In another specific embodiment of this embodiment, the vibrating member can also be directly arranged 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.

[0130] As a specific embodiment, the vibrating member 300 can be a motor equipped with an eccentric wheel, which can generate periodic vibration when rotating.

[0131] As a preferred embodiment, the vibrating member 300 has piezoelectric materials, which will generate the inverse piezoelectric effect after being connected to a high-frequency oscillation circuit, resulting in periodic expansion and contraction of the piezoelectric materials to generate high-frequency vibration.

[0132] When the vibrating member 300 starts to generate high-frequency vibrations, it can drive the fine mesh cylinder 230 to generate high-frequency vibrations. As a result, the lint in the mesh holes of the fine mesh cylinder 230 and the lint attached to the inner wall of the fine mesh cylinder 230 will also vibrate and displace under the action of vibration. The fine mesh cylinder 230 has a thin-wall structure. When the lint stuck in the mesh holes moves out a little, it will enter the water collecting cavity 112 and be discharged together with the washing water. When it moves in a little, it will fall into the micro-lint collecting cavity 232 and be collected, enabling the mesh holes on the fine mesh cylinder 230 to quickly return to an unobstructed state.

[0133] It can be understood that the lint that can pass through the mesh holes of the fine mesh cylinder 230 and enter the water collecting cavity 112 indicates that its diameter is smaller than the aperture of the mesh holes. This size of lint is the lint that is legally permitted to be discharged and will not cause the washing water discharge to not meet the standards.

[0134] In a specific structure, through holes are provided on the upper cover 120, and the power cord connected to the vibrating member 300 and used for power supply passes through the through holes and out of the upper cover 120. The through holes are filled with a sealing member 122 for sealing. In this way, it not only ensures the power supply of the vibrating member 300 but also prevents the washing water from leaking 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.

[0135] In this embodiment, the vibrating member 300 can also 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 can be buoyed by the water due to being immersed in the water and is relatively easy to fall off under the action of vibration.

[0136] For example, the vibrating member 300 can be intermittently started during the drainage process of the washing equipment, or the vibrating member 300 can be started to operate for a period of time when the drainage of the washing equipment is almost completed.

[0137] Of course, the vibrating member 300 can also be continuously turned on throughout the process of filtering the washing water discharged from the washing equipment through the micro-lint collecting device to reduce the adhesion of lint on the fine mesh cylinder 230, thereby improving the drainage efficiency.

[0138] This embodiment also provides a control method for a washing equipment applying the micro-lint collecting device. Specifically, the washing equipment has a drainage pump. The inlet end of the drainage pump is communicated with the water storage cylinder of the washing equipment, and the outlet end is communicated with the drainage pipe of the washing equipment. When the washing equipment drains water, the drainage pump is turned on to pump out the washing water from the water storage cylinder and send it along the drainage pipe into the micro-lint collecting device.

[0139] In this embodiment, after the drainage of the washing device is completed, a filter element drying program is executed to dry the filter element 200 and lint. It should be noted that the "completion of drainage" in this embodiment refers to the end of the last drainage operation in the current washing program.

[0140] The filter element drying program includes: starting the heating component 900 to heat the filter element 200; and after the heating component 900 continuously heats for a certain period of time, starting the drain pump to pump air into the micro-lint collection device.

[0141] In the above solution, after heating the filter element 200 for a certain period of time, controlling the drain pump to run idly to pump a small amount of air into the housing 100 of the micro-lint collection device can quickly discharge the moisture generated by heating, so as to dry the filter element 200 more efficiently.

[0142] Since the heated air will flow upward, and the air flow generated by the driving force of the drain pump in the housing 100 flows downward, which is exactly opposite to the flow direction of the hot air. If the drain pump is controlled to operate while heating, the hot air generated by heating in the housing 100 may be driven away by the downward air flow before it has time to rise, wasting heat.

[0143] To avoid the above problems, the filter element drying program in this embodiment specifically includes the following steps:

[0144] S1. Start the heating component 900 and turn it off after continuously heating for the first preset duration T1;

[0145] S2. Start the drain pump and turn it off after continuously running for the second preset duration T2;

[0146] S3. If the start-up times of the heating component 900 reach the set times, end the filter element drying program; otherwise, return to step S1.

[0147] Through the above solution, both the heating component 900 and the drain pump work intermittently and start alternately, ensuring the full utilization of heat and thus ensuring the drying efficiency. At the same time, this can also prevent the heating component 900 from heating the fine mesh cylinder 230 too quickly, causing the temperature of the fine mesh cylinder 230 to be too high and resulting in the combustion of the micro-lint collected inside.

[0148] In this embodiment, the specific values of the first preset duration T1 and the second preset duration T2 can be set according to the actual situation. Generally, since the electromagnetic heating coil can provide a high heating efficiency, the first preset duration T1 is less than the second preset duration T2.

[0149] As a specific implementation manner, the values of the first preset duration T1 and the second preset duration T2 satisfy: 15 ≤ T2 / T1 ≤ 20. For example, it can be set that the heating component 900 continuously heats for 10 seconds each time it is started, and the drain pump continuously operates for 2 minutes and 30 seconds to 3 minutes and 20 seconds each time it is turned on.

[0150] Generally, when the washing device finishes draining water, the washing water in the micro lint collection device has not been completely drained. At this time, both the fine mesh cylinder 230 and the heating component 900 will be partially immersed in water, and starting the heating component 900 cannot play a role in heating and drying.

[0151] Therefore, in a further solution of this embodiment, the washing device waits for a third preset duration T3 after the drainage ends, and then executes the filter element drying program. The specific value of the third preset duration T3 can be determined through pre-tests, so as to ensure that the moisture in the micro lint collection device has been drained as much as possible under the action of gravity, and then start the heating component 900 to avoid waste of electric energy.

[0152] In a further solution of this embodiment, after the filter element drying program ends, the vibrating member 300 is started to drive the filter element 200 to vibrate. The micro lint with a smaller volume after drying is more likely to be discharged from the mesh holes of the fine mesh cylinder 230. At this time, starting the vibrating member 300 can better realize the self-cleaning of the fine mesh cylinder 230 and ensure the filtering effect when the micro lint collection device is used next time.

[0153] In this embodiment, by arranging the heating component 900 in the micro lint collection device, the filter element 200 can be heated and dried each time the washing device finishes running the washing program, realizing the dry storage of lint, thereby avoiding the lint from mildewing or generating peculiar smells in a humid environment and improving the user experience. By alternately starting the heating component 900 and the drain pump of the washing device, the moisture generated by heating can be discharged as soon as possible, which is beneficial to drying the filter element 200 faster. After the filter element 200 is dried, it is vibrated by the vibrating member 300. The volume of the micro lint shrinks, and it is more likely to fall off or pass through the mesh holes of the fine mesh cylinder 230, which can fully release the mesh holes of the fine mesh cylinder 230 and help extend the service life of the filter element 200.

[0154] Embodiment Three

[0155] As Figures 1 to 3 shown, this embodiment is a further limitation of the above Embodiment One or Two. The filter body includes a first filter body 210 and a second filter body 220 with gradually increasing filtration accuracies, and both are cylindrical structures with a certain wall thickness.

[0156] Specifically, an inlet water cavity 2122 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, so that the micro wire debris collection cavity 232 is formed outside. The filtration accuracy of the fine mesh cylinder 230 is higher than that of the second filter body 220.

[0157] In this embodiment, the filter element 200 forms a step-by-step filtration structure. The washing water to be filtered enters the inlet water cavity 2122, and permeates 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 wire debris in the water can be filtered step by step and finally collected in the water collection cavity 112 outside the fine mesh cylinder 230 and discharged from the water outlet 101.

[0158] The first filter body 210 and the second filter body 220 are three-dimensional space structures with holes inside, which can accommodate more wire debris and are not easily blocked by wire debris. The fine mesh cylinder 230 is arranged on the outermost side, so that the washing water passing through the fine mesh cylinder 230 meets the micro wire debris filtration requirements. The fine mesh cylinder 230 has the greatest resistance to water, and arranging it on the periphery can also increase the filtration area and ensure the water outlet efficiency.

[0159] In addition, in the process of step-by-step filtration, relatively thick wire debris can be collected inside the first filter body 210, the second filter body 220 collects smaller wire debris, and the fine mesh cylinder 230 mainly intercepts micro wire debris. The inlet water cavity 2122 also serves as a large wire debris collection cavity 2121. When the holes inside the first filter body 210 are filled with thick wire debris, the continuously entering thick wire debris will gather in the large wire debris collection cavity 2121. Only when the large wire debris collection cavity 2121 and the first filter body 210 are filled with thick wire debris, the second filter body 220 is filled with ordinary small wire debris, and the micro wire debris collection cavity 232 is filled with micro wire debris, will the whole filter element 200 have poor water outlet, and the user needs to manually clean or replace it.

[0160] Therefore, the step-by-step filtration structure composed of the first filter body 210, the second filter body 220, and the fine mesh cylinder 230 in this embodiment can further extend the service life of the filter element 200.

[0161] In this embodiment, since the service life of the filter element 200 is relatively long, the use cost is spread out. When the service life of the filter element 200 expires, the user can replace the whole filtration main body. Specifically, the user opens the upper cover 120 and takes 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, reinstall a new filtration main body, and then place the filter element 200 with the replaced filtration main body back into the housing 110.

[0162] In another solution, the fine mesh cylinder 230 is made of stainless steel and can be reused. When the user cleans the filter element 200, only the internal first filter body 210 and second filter body 220 are replaced, and the replacement cost is lower. Specifically, after the user removes the filter element 200 from the housing 110, the fine mesh cylinder 230 can be removed from the end cap 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, a new filter body can be installed first, which can be directly installed on the end cap 250 or installed in the cleaned fine mesh cylinder 230, and then the fine mesh cylinder 230 is reinstalled on the end cap 250. After that, the filter element 200 can be placed back into the housing 110.

[0163] In another specific implementation manner of this embodiment, three or more concentric cylindrical filter bodies can be arranged outward from the large lint collection cavity, and the filtration precision of each cylindrical filter body is different, and the filtration precision increases one by one from the inside to the outside.

[0164] 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 the micro lint collection cavity 232 is formed between the first mesh cylinder 221 and the fine mesh cylinder 230.

[0165] 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. Or, in another specific structure, the first filter body can be similar to the second filter body and is arranged as a cylindrical shape with the upper end open and the lower end closed.

[0166] 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 relatively large-sized water-permeable holes, and various-sized 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 only serve to gather the first filter body 210 and the second filter body 220 and maintain their cylindrical structures.

[0167] 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.

[0168] In a specific embodiment, both the first filter body 210 and the second filter body 220 are made of loofah or a block-shaped material with a loofah-like structure. Among them, compared with the first filter body 210, the second filter body 220 is filled with block-shaped materials processed into smaller sizes, or the same filler but pressed more tightly.

[0169] During manufacturing, the second cylinder 212 and the third cylinder 211 can be pre-fixed at the lower end, and then the block-shaped materials for forming the first filter body 210 are filled between the second cylinder 212 and the third cylinder 211. The processed first filter body 210 and the whole formed by the second cylinder 212 and the third cylinder 211 are placed at the center of the first cylinder 221, and then the block-shaped materials for forming the second filter body 220 are filled into the gap between the first cylinder 221 and the third cylinder 211.

[0170] When the size of the block-shaped materials of the second filter body 220 is smaller, it can be slightly compacted after filling. If block-shaped materials of the same size are used to form the first filter body 210 and the second filter body 220 respectively, it is necessary to compact more fully after the filling of the block-shaped materials of the second filter body 220 is completed.

[0171] The above-mentioned block-shaped material with a loofah-like structure can be an artificial block-shaped material similar to a loofah shape and having a three-dimensional maze structure with many thick holes inside, or other plant fibers that can form a three-dimensional network structure with holes inside, or can be granular or powdery wood chips.

[0172] In a preferred solution of this embodiment, the first filter body 210 and the second filter body 220 are made of loofah, which is a natural plant component, absorbs carbon dioxide during production, can be naturally degraded after being discarded, and hardly produces carbon dioxide during degradation, making it suitable as a directly replaceable filter consumable and conforming to the environmental protection concept. On the other hand, the loofah itself has many relatively large holes, and in addition, the melon netting forming 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.

[0173] As a specific embodiment, 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.

[0174] Among them, the first filter body 210 itself has many relatively large holes that can accommodate relatively large lint. Among the lint generated during the laundry process, the thick lint accounts for the largest proportion. 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 sponge. The mesh structure forming the holes 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 that of the first filter body 210, which is also beneficial to ensuring that the two have approximately the same drainage speed.

[0175] In an alternative solution of this embodiment, 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-shaped sponge can be used to fill and form the second filter body 220.

[0176] It should be noted that for the solution provided with the vibrating member 300, since 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 therefrom and gather towards the micro-lint collecting cavity 232, occupying the space of the micro-lint collecting cavity 232.

[0177] As a preferred embodiment, the first mesh cylinder 221, the second mesh cylinder 212, and the third mesh cylinder 211 respectively have a Figure 5 frame 260 as shown, and are made by wrapping a plastic mesh with thick holes around the frame 260, which is more economical. The frame 260 can be a hollow prismatic structure or a hollow cylindrical structure.

[0178] 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 lower surface of the end cap 250 inside the annular wall 252, and the upper end of the second filter body 220 is limited inside the limiting ring 240.

[0179] 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 surface of the end cap 250, and the upper end of the first mesh cylinder 221 is clamped inside the limiting ring 240.

[0180] 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-lint collecting cavity 232.

[0181] In a further solution, a bottom wall of the fine mesh cylinder 230 is locally convex upward to form a positioning portion 231, and a 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 limit fit.

[0182] In a specific structure, a positioning portion 231 is convex 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 concave 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 limit fit for the assembly positioning of the fine mesh cylinder 230 and the second filter body 220.

[0183] In a specific implementation manner of the structure in which the filter element 200 is suspended, when the filter element 200 is suspended inside the housing 100, the height of the end cover 250 is close to the joint 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 cover 250, and thus the fine mesh cylinder 230 can be removed from the end cover 250.

[0184] When the user uses the micro wire chip collecting device provided in this embodiment, an operation process for cleaning the filter element 200 is specifically as follows:

[0185] 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 and the housing 110. 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 holds the end cover 250 and the fine mesh cylinder 230 and rotates them relative to each other, and the fine mesh cylinder 230 can be removed from the end cover 250. Since the micro wire chips are collected inside the fine mesh cylinder 230, the user will not contact the micro wire chips.

[0186] Then, 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, and let the filter body abut against one side of the trash can, so that the filter body and the end cover 250 can be separated by using the trash can. Thus, the user does not need to contact the damp or even moldy filter body with hands, and can complete the replacement more hygienically and quickly.

[0187] 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 portion 231 and the concave structure 2211, and then installs the two together back onto the end cover 250.

[0188] In the solution of this embodiment, the first filter body 210 and the second filter body 220 have a three-dimensional space structure. Compared with the solution where an ordinary multi-layer filter screen structure needs to be replaced when lint covers all the holes of the filter screen, the cleaning and replacement cycle of the filter element 200 is greatly extended. At the same time, the first filter body 210, the second filter body 220 and the fine mesh cylinder 230 form a step-by-step filtration structure, and the first filter body 210 and the second filter body 220 themselves can also filter part of the fine lint, so that less fine lint reaches the fine mesh cylinder 230. Coupled 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.

[0189] By collecting and analyzing the fine 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 the spaces for accommodating lint in the fine lint collection device of this embodiment (including the large lint collection cavity 2121, the first filter body 210, the second filter body 220 and the fine lint collection cavity 232) is reasonably designed, so that each space reaches the replacement standard at the same time, which can better exert the potential of the filter element 200, extend the service life and reduce the replacement cycle.

[0190] Embodiment Four

[0191] As Figure 6 shown, the difference between this embodiment and the above embodiment is that the outlet end of the overflow pipe 520 is directly connected to the water collection cavity 112 between the filter element 200 and the housing 100.

[0192] Specifically, in this embodiment, the housing 100 is provided with a communication port communicating with the internal water collection cavity 112 in the area other than the water inlet 102 and the water outlet 101. After the overflow pipe 520 passes through the side wall of the water inlet joint 121, it extends towards the communication port, and the outlet end is directly connected to the communication port, or extends into the water collection cavity 112 through the communication port.

[0193] In this way, the washing water carrying lint can flow along the overflow pipe 520, bypass the filter element 200 and directly enter the water collection cavity 112, and be discharged from the water outlet 101 together with the filtered washing water.

[0194] For the structure where the filter element 200 is suspended in the housing 100, since there is no direct contact between the filter element 200 and the housing 100, the water collection cavity 112 completely wraps the filter element 200. At this time, the communication port can be set in any area of the housing 100 other than the water inlet 102 and the water outlet 101.

[0195] As a specific implementation, the top surface of the filter element 200, that is, the upper side surface of the end cap 250, is spaced from the inner surface of the top wall of the housing 100. The overflow water pipe 520 bends downward after passing through the side wall of the water inlet joint 121, passes through the top wall of the housing 100 and communicates with the water collecting cavity 112.

[0196] It can be understood that the housing 100 is composed of a detachable upper cover 120 and a housing body 110. In the above solution, the communication port for the overflow water pipe 520 to extend into the water collecting cavity 112 is arranged on the upper cover 120, preferably at a position close to the water inlet 102.

[0197] With the above structure, the overflow water pipe 520 is completely installed on the upper cover 120 and can use a rigid pipe without affecting the disassembly between the upper cover 120 and the housing body 110. At the same time, compared with the solution in the first embodiment, the length of the overflow water pipe 520 can be greatly shortened, avoiding occupying too much space outside the housing 100.

[0198] In a preferred solution of this embodiment, when a heating component 900 is arranged inside the housing body 110, the heating component 900 is selected to use an electromagnetic heating coil for heating.

[0199] Since the outlet end of the overflow water pipe 520 is located in the top area of the water collecting cavity 112, the washing water carrying lint discharged along the overflow water pipe 520 will flow downward in the water collecting cavity 112 and contact the electromagnetic heating coil of the heating component 900 before being discharged from the water outlet 101, and thus lint may adhere and remain on the surface of the electromagnetic heating coil.

[0200] The working principle of the electromagnetic heating coil is to utilize the high-frequency alternating magnetic field to excite the eddy current effect in the fine mesh cylinder 230, and then make the fine mesh cylinder 230 generate heat by itself, and the temperature of the electromagnetic heating coil itself will not increase significantly during the working process. Therefore, selecting the electromagnetic heating coil for the heating component 900 can avoid the risk of lint remaining on the heating component 900 burning during the heating process.

[0201] In this embodiment, the overflow water pipe 520 is directly connected to the water collecting cavity 112 through the top wall of the housing 100, and the purpose of emergency drainage can also be achieved. On the one hand, the overflow water pipe 520 can be integrally installed on the upper cover 120, and when the user cleans the filter element 200, the upper cover 120 can be completely separated from the housing body 110, which is more convenient for operation. On the other hand, the extension length of the overflow water pipe 520 can be reduced, and the space occupied by the overflow water pipe 520 outside the housing 100 can be reduced, making the overall structure of the micro lint collection device more stable and reliable.

Although the present invention has been disclosed as above with the preferred embodiments, it is not intended to limit the present invention.
