Description

Technical Field

[0001] This invention relates to the field of washing equipment technology, and specifically provides a washing tub assembly for a shoe washing device. Background Technology

[0002] A shoe washing machine is a specialized device for cleaning shoes. Most shoe washing machines on the market currently have a barrel-shaped component inside to hold the washing water and shoes. During washing, a brush inside the barrel scrubs the surface of the shoes to achieve the purpose of cleaning. In addition, to prevent washing water from splashing out of the barrel, some shoe washing machines also have an openable and closable lid at the opening of the barrel. This lid is pivotally installed at the opening to prevent washing water from splashing out of the barrel.

[0003] The drawback of the aforementioned shoe washing machine is that the barrel-shaped component is usually designed to rotate. After the shoes are washed, the position of the barrel-shaped component when it stops rotating cannot guarantee that the open side of the lid is close to the user. At this time, on the one hand, the handle and other operating components on the lid may not be in a direction that is convenient for the user to grip and apply force, making it very inconvenient for the user to open the lid. On the other hand, even if the user opens the lid, the position of the lid after opening is very likely to block the front of the bucket opening and prevent the user from taking the shoes out from the bottom of the bucket, resulting in poor convenience for taking out shoes.

[0004] Accordingly, there is a need in the art for a new washing tub assembly for shoe washing equipment to address the aforementioned problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to improve or solve to a certain extent the problems that the orientation of the bucket lid of the existing shoe washing machine is difficult to guarantee after the shoe washing is completed, and that the bucket lid may be difficult for the user to open smoothly or may affect the user's smooth removal of shoes after opening.

[0006] This invention provides a washing tub assembly for a shoe washing device. The washing tub assembly includes a washing tub, multiple sector-shaped plates, and a locking assembly. The arc-shaped edges of the sector-shaped plates are pivotally connected to the opening of the washing tub, and the multiple sector-shaped plates are distributed circumferentially along the opening of the tub so that when all the sector-shaped plates are closed, they can form a complete cover. At least one elastic torsion member is provided between the sector-shaped plates and the washing tub. The elastic torsion member can cause the sector-shaped plates to pivot open by rebound. The locking assembly includes a limiting groove provided on any one of the multiple sector-shaped plates and a pressing member that slides with the limiting groove. The limiting groove is provided along the top side surface of the sector-shaped plate. The limiting groove is configured to allow the pressing member to slide outward to a position that can press against all the sector-shaped plates when the sector-shaped plates are closed, so that all the sector-shaped plates overcome the elastic force and remain closed. It also allows the pressing member to slide back to allow all the sector-shaped plates to pivot open.

[0007] With the above technical solution, the washing tub of the present invention can be closed and blocked by multiple sector-shaped plates. When the lid needs to be opened, the multiple sector-shaped plates automatically spring open. When the lid needs to be closed, the pressing member slides out from the limiting groove and presses against the top of each sector-shaped plate, ensuring that all sector-shaped plates are reliably kept closed. This allows the user to automatically open and close the multiple sector-shaped plates simply by pushing the pressing member, making operation simple. Furthermore, when the lid is open, the multiple sector-shaped plates are arranged upright along the circumference of the tub opening. The vertical height of the sector-shaped plates is low, and a large triangular gap can be formed between the sector-shaped plates, so as to create a sufficiently large operating space above the tub opening for the user to use, facilitating the user to smoothly take off and put away shoes after opening the lid.

[0008] In the preferred embodiment of the above-mentioned washing tub assembly, the limiting groove is arranged radially along the washing tub, and the opening of the limiting groove faces the tip of the fan-shaped plate. When the pressing member slides out into place, one end of the pressing member is engaged in the limiting groove, and the other end of the pressing member slides to the center area of ​​the opening of the washing tub. The bottom of the pressing member abuts against the top side surface of each fan-shaped plate.

[0009] When the above technical solution is adopted, the pressing member slides outward to the middle position of the barrel opening and can press against the tip of multiple sector plates. This makes it possible to minimize the sliding stroke of the pressing member while meeting the locking and limiting requirements of all sector plates, and optimize the size of the pressing member.

[0010] In the preferred embodiment of the above-mentioned washing tub assembly, the pressing member is provided with a blocking structure. The blocking structure is located at the tail end of the pressing member and outside the end of the limiting slide groove. The blocking structure can prevent the pressing member from sliding out of the limiting slide groove in the sliding direction by abutting against the end of the limiting slide groove.

[0011] By adopting the above technical solution, it is possible to prevent the pressing component from slipping out of the limiting groove due to excessive sliding, thereby improving the installation reliability of the pressing component.

[0012] In the preferred embodiment of the above-mentioned washing tub assembly, the sector plate includes a first sector plate and multiple second sector plates. The limiting groove is disposed on the top of the first sector plate. The locking assembly further includes a first claw, a hook, and a first elastic member. At least one of the second sector plates is provided with the first claw on its top. The hook is disposed in a one-to-one correspondence with the first claw. The hook is connected to the pressing member through the first elastic member. The first elastic member is configured to support the hook to pop outward in its natural state and to allow the hook to retract when the pressing member slides along the first claw. When the pressing member slides outward to a position that can press against all the second sector plates, the hook engages with the downstream side of the first claw.

[0013] When the above technical solution is adopted, the pressing member can not only press and limit the upper part of each sector plate, but also engage with at least one first claw, which further improves the pressing reliability of the pressing member. In addition, the pressing part of the pressing member can form a locking and limiting point at the first claw position, so as to share part of the force exerted on the pressing part of the sector plate due to the outward elasticity of the pressing member, reduce the strength setting requirements of the pressing member, and extend the service life of the pressing member.

[0014] In the preferred embodiment of the washing tub assembly described above, the washing tub assembly further includes a second elastic member, which is disposed between the tail end of the pressing member and the fan-shaped plate / washing tub. The second elastic member can allow the pressing member to slide outward by stretching deformation, so as to cause the pressing member to reset by contraction and rebound.

[0015] When the above technical solution is adopted, on the one hand, the pressing component can be reset and rebound when the cover is opened and unlocked, which improves the convenience of unlocking operation. On the other hand, when the pressing component is provided with a first claw for engaging, the pressing component can be tightened by the rebound tendency of the pressing component, thereby causing the claw to abut tightly against the engagement point with the first claw, further optimizing the locking reliability of the pressing component and preventing the pressing component from colliding with the fan-shaped plate, the limiting groove or the first claw and other engaging positions during shoe washing, thus generating noise.

[0016] In the preferred embodiment of the above-mentioned washing tub assembly, the sector plate includes a first sector plate and multiple second sector plates. The limiting groove is disposed on the top of the first sector plate. The locking assembly further includes a second claw. At least one of the second sector plates is provided with the second claw. When the pressing member slides outward to a position that can press against all the second sector plates, the pressing member can slide in and be locked in the second claw.

[0017] When the above technical solution is adopted, the second claw can guide the pressing member to slide when the pressing member slides outward, preventing the pressing member from deviating from the sliding direction and sliding out skewedly, thus affecting the pressing effect. Furthermore, the engagement between the second claw and the pressing member can further optimize the pressing stability of the pressing member, and can also distribute part of the force applied to the pressing member by the fan-shaped plate to the engagement position of the second claw, thereby avoiding concentrated force on a certain point of the pressing member to a certain extent, and improving the durability of the pressing member by dispersing the force.

[0018] In the preferred embodiment of the washing tub assembly described above, there are multiple second claws, and at least a portion of the multiple second claws are arranged opposite each other along the sliding direction.

[0019] When the above technical solution is adopted, the relatively arranged second claw can form a plate surface movement limit on the opposite sides of the pressing member, so that the second claw can assist the limiting slide groove in guiding the pressing member when it slides, optimize the guiding effect of the second claw on the pressing member, and further improve the locking stability of the pressing member by relatively locking.

[0020] In the preferred embodiment of the above-mentioned washing tub assembly, the pressing member is provided with a plug-in post, the sector plate provided with the limiting slide groove is provided with a guide groove, the guide groove is provided along the sliding direction, and the plug-in post is slidably inserted into the guide groove.

[0021] When the above technical solution is adopted, the guide groove can assist the limiting guide groove in guiding the sliding of the pressing member and restrict the pressing member from deviating relative to the expected sliding direction, further ensuring that the pressing member can accurately slide to the position where it can press and lock all the sector plates.

[0022] In the preferred embodiment of the above-mentioned washing tub assembly, a shoe washing structure is provided at the bottom of the fan-shaped plate, the shoe washing structure is disposed downwards, and when the fan-shaped plate is closed, at least a portion of the shoe washing structure is located within the washing space of the washing tub.

[0023] With the above technical solution, the shoe washing structure can enter the inner space of the washing tub after the fan-shaped plate is closed, so that the shoe washing structure can clean the light shoes floating on the top of the washing water in the washing tub, increase the cleaning angle of the shoes, and improve the overall shoe washing effect. At the same time, this way of connecting the shoe washing structure to the bottom of the fan-shaped plate can also make the shoe washing structure move to the top of the washing tub each time the lid is opened, which greatly improves the convenience for users to clean the dirt and lint attached to the shoe washing structure.

[0024] In the preferred embodiment of the above-mentioned washing tub assembly, the shoe washing structure is positioned close to the tip of the fan-shaped plate, so that the shoe washing structures on different fan-shaped plates can be combined into a whole brush body when all the fan-shaped plates are closed, and the radial dimension of the brush body gradually increases from the top of the brush to the bottom of the brush.

[0025] By adopting the above technical solution, the brush body assembled from the shoe washing structure can have an expanded brushing surface. When the shoes and washing water are agitated, the vortex of washing water near the brush body can cause the lighter shoes floating above the washing water to rotate around the brush body, so that all the lighter shoes in the bucket can be reliably cleaned by the expanded bristles of the brush body for a long time. Furthermore, the expanded brush body can also reliably receive shoes floating from below, and can rub against the shoes from any position in its circumference, increasing the brushing angle and greatly optimizing the overall shoe washing effect of the shoe washing equipment.

[0034] Those skilled in the art should understand that, in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] It should also be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] like Figure 1-5As shown, the washing tub assembly of the present invention is disposed within the outer casing (not shown in the figure) of a shoe washing device. The washing tub assembly includes a washing tub 1 (the portion of the washing tub 1 shown in the figure refers to the opening portion of the washing tub 1), multiple sector plates 2, and a locking assembly 3. All sector plates 2 can be approximately assembled into a single circular plate, and this assembled circular plate is adapted to the shape of the opening of the washing tub 1 so that when all sector plates 2 are installed at the opening position, they can be closed into a complete circle or near-circular cover to prevent splashing washing water from inside the tub. Specifically, the multiple sector plates 2 are distributed circumferentially along the opening of the washing tub 1, and each sector plate 2 has a pivot connection structure 21 on its arc-shaped side. This pivot connection structure 21 is pivotally connected to the opening position of the washing tub 1 to allow the sector plate 2 to rotate and open / close relative to the opening. At least one elastic torsion member is provided between each sector plate 2 and the washing tub 1. When the sector plate 2 is closed, the elastic torsion member undergoes elastic torsion deformation due to the pressure (or stretching) of the sector plate 2, so that it can cause the sector plate 2 to pivot open by means of expansion and rebound (or contraction and rebound). The locking assembly 3 includes a limiting groove 31 and a pressing member 32 that slides with the limiting groove 31. The above-mentioned multiple sector plates 2 are divided into two categories. One category is the first sector plate 2A, which is one in number. The limiting groove 31 is provided on the top side plate surface of the first sector plate 2A (i.e., the side plate surface facing away from the inside of the tub). All the remaining sector plates 2 that do not require the setting of the limiting groove 31 are the second sector plates 2B. The limiting slide groove 31 extends along the top side surface of the first sector plate 2A. The side of the limiting slide groove 31 has an opening 31A that allows communication with the outside. The pressing member 32 is slidably engaged within the limiting slide groove 31, and can slide into or out of the limiting slide groove 31 through the opening 31A. The limiting slide groove 31 is also configured to allow the pressing member 32 to slide outwards to a position that can press against all the sector plates 2 when the first sector plate 2A and all the second sector plates 2B are closed, so as to cause all the sector plates 2 to overcome the elastic force and remain closed. Furthermore, it also allows the pressing member 32 to slide back to allow all the sector plates 2 to pivot and spring open.

[0037] Based on the above configuration, when it is necessary to open the lid to expose the internal space of the bucket, the pressing member 32 is located within the limiting groove 31 and does not slide outward. The pressing member 32 is entirely at the top of the first sector plate 2A and does not extend outward relative to the edge of the first sector plate 2A. There is no pressing engagement between the pressing member 32 and the first sector plate 2A and all the second sector plates 2B, and the first sector plate 2A and the second sector plate 2B can be freely rotated.

[0038] So that all the sector plates 2 can be flipped open away from the barrel opening under the rebound support of their respective elastic torsion members.

[0039] When the bucket opening needs to be closed, the first sector plate 2A and all the second sector plates 2B are completely closed. All the sector plates 2 are closed into a single cover, reliably blocking the washing water splashing out of the bucket. The pressing member 32 slides out from the slot 31A and moves to a position where it can press against all the second sector plates 2B. When the pressing member 32 slides out to this position, it is located on the top upper side of the cover composed of all the sector plates 2, and the bottom of the pressing member 32 presses against a portion of each sector plate 2. The locking engagement between the limiting groove 31 and the pressing member 32 restricts the pressing member 32 from moving away from this position, causing the pressing member 32 to reliably press against the top of all the sector plates 2, so that the first sector plate 2A and all the second sector plates 2B are restricted from flipping by the pressing member 32, thereby causing the first sector plate 2A and all the second sector plates 2B to overcome the rebound of their respective elastic torsional members and remain in a closed state.

[0040] When it is necessary to expose the barrel opening, simply slide the pressing member 32 back into the slide groove. The first sector plate 2A and all the second sector plates 2B can automatically pop open after the pressing limit of the pressing member 32 disappears.

[0041] In the above embodiments, it should be noted that the structure of the washing tub 1 is not limited. The washing tub 1 can be a single-layer water-holding tub disposed within the outer shell. In this case, the first sector plate 2A and all the second sector plates 2B are pivotally connected to the opening of the water-holding tub. The first sector plate 2A and all the second sector plates 2B are used to cover or open the opening of the water-holding tub. When the water-holding tub is rotatable, the first sector plate 2A and all the second sector plates 2B rotate synchronously with the water-holding tub. Alternatively, the washing tub 1 may also include an outer tub fixed within the outer shell and an inner tub coaxially disposed within the outer tub. In this case, the first sector plate 2A and all the second sector plates 2B are pivotally connected to the opening of the inner tub. The first sector plate 2A and all the second sector plates 2B are used to cover or open the opening of the inner tub. When the inner tub is rotatable, the first sector plate 2A and all the second sector plates 2B rotate synchronously with the inner tub.

[0042] The cover plate assembled from all the sector plates 2 can be a single, essentially seamless circular cover plate (e.g., Figure 2The circular cover shown can also be a near-circular cover with gaps at any splicing position, such as the center or the side of the diameter, as long as the cover structure formed by all the sector plates 2 can basically meet the covering requirements of the washing tub 1. Furthermore, the number of the aforementioned second sector plates 2B is at least one, and the shapes of similar second sector plates 2B and different types of first sector plates 2A and second sector plates 2B can be the same or different. For example, one of the multiple second sector plates 2B has a radius of 15 cm and a central angle of 80 degrees, while another has a radius of 14 cm and a central angle of 90 degrees. Similarly, the radius and central angle of the first sector plate 2A can be set to the same or different values ​​as the radius and central angle of any second sector plate 2B, as long as the shape of all the sector plates 2 meets their splicing requirements and the sector plates 2 do not interfere with each other's rotation and opening / closing. As an example, Figure 1 and Figure 2 The diagram shows a case where the first sector plate 2A and each of the second sector plates 2B have the same shape, and there are two second sector plates 2B. In this case, when all the sector plates 2 are closed, the first sector plate 2A and the two second sector plates 2B can be assembled into a circular cover plate without obvious gaps.

[0043] Furthermore, the method of pivoting the first sector plate 2A / second sector plate 2B to the washing tub 1 is not limited. For example, the pivoting connection structure 21 of the first sector plate 2A / second sector plate 2B is provided with a shaft hole 211, and the inner edge of the tub opening of the washing tub 1 is provided with a mounting groove 11 or other mounting shaft setting structure for fixing the mounting shaft, so that the first sector plate 2A / second sector plate 2B can rotate to open and close after the mounting shaft is pivotally connected to the shaft hole 211. Alternatively, the pivoting connection structure 21 of the first sector plate 2A / second sector plate 2B is provided with a mounting shaft, and the tub opening of the washing tub 1 is provided with a shaft hole that can pivotally connect to both ends of the mounting shaft, so that the first sector plate 2A / second sector plate 2B can be pivotally connected to the washing tub 1.

[0044] Furthermore, the aforementioned elastic torsion member is any elastic member capable of causing the first sector plate 2A / second sector plate 2B to flip open through elastic torsion deformation, such as a torsion spring or a V-shaped spring. One end of the two torsion ends of the elastic torsion member is fixed to the washing tub 1 or the mounting shaft, and the other end is fixed to the first sector plate 2A / second sector plate 2B, so that it can be pulled open and twisted or compressed and twisted when the first sector plate 2A / second sector plate 2B is closed, thereby causing the first sector plate 2A / second sector plate 2B to flip open through contraction rebound or expansion rebound.

[0045] Furthermore, the shapes of the aforementioned limiting groove 31 and pressing member 32 are not limited, as long as the specific shape of the limiting groove 31 can meet its guiding and limiting requirements, and the specific shape of the pressing member 32 can meet its pressing requirements against all the sector plates 2. For example, the limiting groove 31 can be a straight groove structure or an arc-shaped groove structure, and its groove sidewalls can be continuously enclosed, or it can only include a set of oppositely arranged slide rail structures (i.e., Figure 1-2 (The shape of the limiting groove 31 shown in Figure 4) Correspondingly, the shape of the pressing member 32 can be set according to the specific structure of the limiting groove 31 and the specific pressing requirements corresponding to the actual arrangement of the fan-shaped plates 2.

[0046] In one possible scenario, the sliding out and sliding back of the aforementioned pressing member 32 are both operated manually. When the cover is closed or unlocked, the user manually pushes and pulls the pressing member 32, thereby causing the pressing member 32 to slide out to a position that can press against all the fan-shaped plates 2 or slide back into the limiting groove 31.

[0047] In another possible scenario, the aforementioned washing tub assembly also includes a drive device connected to the pressing member 32. This drive device drives the pressing member 32 to slide out and back, thereby enabling the pressing member 32 to automatically slide out and lock when the lid is closed, and to automatically slide back and unlock when the lid needs to be opened. For example, the pressing member 32 may have a rack along the sliding direction. The drive device includes a drive gear and a motor capable of driving the drive gear to rotate forward and backward. The drive gear meshes with the rack, so that the drive gear drives the rack to reciprocate through forward and reverse rotation, thereby causing the pressing member 32 to slide back and forth.

[0048] In any of the above situations, preferably, the limiting groove 31 is arranged radially along the washing tub 1, and the opening of the limiting groove 31 faces the tip of the first sector plate 2A, so that the pressing member 32 can slide towards the center area of ​​the washing tub 1 after it slides out. When the pressing member 32 slides out to the position (i.e., slides out to the position that can meet the rotation limiting requirements of all sector plates 2), the tail end of the pressing member 32 is engaged in the limiting groove 31, and the sliding end of the pressing member 32 slides to the center area of ​​the tub opening of the washing tub 1, so that the bottom of the pressing member 32 can abut against a part of the top side plate of each sector plate 2 respectively, thereby reliably limiting the reliable opening of all sector plates 2.

[0049] With the above configuration, the sliding end of the pressing member 32 can press against the top of the tip of each sector plate 2, so as to extend the distance between the position where the pressing member 32 applies pressure and the position where the elastic torsion member is set, thereby increasing the pressure wall so that the pressing member 32 can reliably press all the sector plates 2 with a smaller pressure.

[0050] like Figure 1-2As shown in Figure 5, in the first embodiment of the present invention, a blocking structure 321 is provided on the pressing member 32. The blocking structure 321 is provided at the tail end of the pressing member 32 (the end away from the sliding end of the pressing member 32). When installed, the pressing member 32 is locked in the limiting slide groove 31. The blocking structure 321 protrudes outside the groove tail 31B of the limiting slide groove 31 and is located outside the groove tail 31B of the limiting slide groove 31, so that the blocking structure 321 can prevent the pressing member 32 from disengaging from the limiting slide groove 31 along the sliding direction by abutting against the groove tail 31B of the limiting slide groove 31 when the pressing member 32 slides out of the groove.

[0051] Furthermore, the aforementioned locking assembly 3 also includes a first claw 33, a hook 34, and a first elastic member (not shown in the figure). At least one of the second sector plates 2B is provided with a first claw 33 on its top. The root of the first claw 33 is connected to the second sector plate 2B. The penetrating direction of the claw hook structure of the first claw 33 is the same as the sliding direction of the pressing member 32. Figure 1-2 The first claw 33 shown in Figure 4 has an inverted L-shaped claw structure. The number of hooks 34 is equal to that of the first claw 33 and they are paired one by one. The hooks 34 are connected to the sliding end of the pressing member 32 through a first elastic member. The first elastic member is configured to support the hooks 34 to pop outward in their natural state and to allow the hooks 34 to retract when the pressing member 32 slides along the first claw 33. Based on the above structure, after the pressing member 32 slides out of the limiting groove 31, the sliding end of the pressing member 32 continuously approaches the first claw 33 until the sliding end abuts against the outer end of the claw hook structure through the outwardly extending hook 34. At this time, the pressing member 32 continues to slide, and the hook 34 is forced by the pressure of the claw hook structure to compress and deform the first elastic member, so that the sliding end slides into the claw hook structure of the first claw 33 by retracting the hook 34. When the pressing member 32 continues to slide out to the position that can press against all the second sector plates 2B, the hook 34 slides along the inner side of the claw hook structure and slides out to the outside of the claw hook structure. The pressure on the hook 34 disappears, the first elastic member rebounds and causes the hook 34 to pop out again, so that the outwardly popped hook 34 is engaged with the downstream side of the first claw 33 (the side of the first claw 33 away from the limiting groove 31), and the side of the pressing member 32 is engaged with the claw hook structure.

[0052] With the above configuration, on the one hand, the engagement and limiting of the downstream side of the first claw 33 with the hook 34 can restrict the unexpected retraction of the pressing member 32, ensuring that the pressing member 32 reliably maintains its state of pressing against all the sector plates 2. On the other hand, when the side of the pressing member 32 is engaged in the claw hook structure of the first claw 33, the claw structure can also limit the pressing member 32 from moving upward away from the sector plate 2, so that the first claw 33 can assist the limiting groove 31 in limiting the pressing member 32, ensuring that the pressing member 32 can only slide back and forth in the expected sliding direction.

[0053] As an example, the sliding end of the pressing member 32 is provided with a receiving groove that can accommodate the hook 34. The receiving groove is connected to the outside, and the hook 34 is disposed in the receiving groove. One end of the first elastic member is connected to the receiving groove, and the other end is connected to the hook 34. In the natural state, the first elastic member naturally extends, and the hook 34 is supported by the first elastic member and pops outward, protruding outside the receiving groove. Under pressure, the hook 34 retracts into the receiving groove, and the first elastic member is deformed by pressure so that when the pressure on the hook 34 is removed, the first elastic member can support the hook 34 to pop outward again by rebound. The first elastic member can be any elastic element that can meet the requirements of elastic support and reset, such as a spring member or a leaf spring member connected between the receiving groove and the hook 34.

[0054] Furthermore, the washing tub assembly of the present invention also includes a second elastic member 4, which is disposed between the tail end of the pressing member 32 and the fan-shaped plate 2 / washing tub 1. When the pressing member 32 slides outward from the slot 31A of the limiting slide groove 31 and is engaged with the first claw 33 by the hook 34, the second elastic member 4 is stretched by the pressing member 32 and undergoes elastic deformation. In the case of opening and unlocking the lid, the hook 34 is pressed back, and the engagement between the pressing member 32 and the downstream side of the first claw 33 is disengaged. The second elastic member 4 pulls the pressing member 32 toward the limiting slide groove 31 by contraction and rebound, causing the pressing member 32 to slide back to the top of the first fan-shaped plate 2A so as to allow each fan-shaped plate 2 to automatically open. Among them, the situation where the hook 34 is pressed and retracted under the above-mentioned opening condition can be that the user directly pinches the hook 34 to cause the hook 34 to retract, or the user (or driving device) directly pulls the pressure member 32 towards the limiting slide groove 31, and the first claw 33 and the hook 34 are disengaged by the unlocking pull force.

[0055] Preferably, the pressing member 32 is further provided with a plug-in post 322. The first sector plate 2A is provided with a guide groove 22 along the direction perpendicular to the plate surface. The guide groove 22 is provided along the sliding direction. The plug-in post 322 is slidably inserted into the guide groove 22. When the pressing member 32 slides out of or back into the limiting slide groove 31, the plug-in post 322 slides back and forth in the guide groove 22 with the pressing member 32, so as to assist the limiting slide groove 31 in restricting the pressing member 32 and promoting the pressing member 32 to slide reliably along the sliding direction.

[0056] For example, when the second elastic member 4 is provided, the plug-in post 322 can be used as the mounting structure for the second elastic member 4. Specifically, the second elastic member 4 can be a spring. The end of the plug-in post 322 away from the pressing member 32 is provided with a hanging hole. The bottom of the first sector plate 2A is provided with a connecting post 23. The end of the connecting post 23 away from the first sector plate 2A is provided with a hanging hole. One end of the spring is hooked into the hanging hole of the plug-in post 322, and the other end is connected to the hanging hole of the connecting post 23. Figure 3 The diagram shows the situation where the two ends of the spring are connected to the insertion post 322 and the connecting post 23 respectively, and two sets of guide grooves 22, insertion posts 322 and connecting posts 23 are provided between the pressing member 32 and the first sector plate 2A.

[0057] In the second embodiment of the present invention, the locking component 3 does not include the first claw 33, the hook 34, and the first elastic member, but the locking component 3 includes a second claw (not shown in the figure). At least one of the second sector plates 2B is provided with a second claw. The claw hook structure of the second claw allows the side of the pressing member 32 to slide in and be engaged therein, so that when the pressing member 32 slides outward to a position that can press against all the second sector plates 2B, the pressing member 32 can be restricted from moving away from the plate surface by engaging with the claw hook structure of the second claw, thereby further improving the pressing reliability of the pressing member 32 against all the sector plates 2. As an example, the shape of the second claw is approximately the same as the shape of the first claw 33, which is an upwardly extending L-shaped claw.

[0058] Furthermore, there are multiple second claws, and at least a portion of the multiple second claws are arranged opposite each other along the sliding direction so as to engage with the two sides of the pressing member 32 respectively. This not only restricts the pressing member 32 from moving up and down relative to the surface of the fan-shaped plate 2, but also assists the limiting groove 31 in limiting the movement of the pressing member 32 in the non-sliding direction.

[0059] In the third embodiment of the present invention, the locking component 3 includes a first claw 33, a hook 34, a first elastic member, and a second claw. The second claw is disposed between the first claw 33 and the limiting slide groove 31. During the process of the pressing member 32 sliding out to a position that can press against all the fan-shaped plates 2, the pressing member 32 first slides into the second claw and engages with the second claw, and then slides into the first claw 33 and engages with the claw hook structure and the downstream side of the first claw 33 respectively.

[0060] In any of the above embodiments, preferably, a shoe washing structure 5 is provided at the bottom of the first sector plate 2A and / or the second sector plate 2B. The shoe washing structures 5 are all arranged downwards so that at least a portion of the shoe washing structure 5 can be located within the washing space of the washing tub 1 when the lid is closed, thereby rubbing and brushing the lightweight shoes floating in the washing water within the washing tub 1. This arrangement improves the cleaning effect of the shoe washing machine on lightweight shoes that are difficult to reliably rub and wash. Furthermore, the shoe washing structure 5 can be easily moved above the tub opening by opening the lid, improving the ease of operation for users when cleaning and maintaining the shoe washing structure 5.

[0061] More preferably, the washing tub 1 is rotatably configured, such as by rotating the water tank or inner tub, and a pulsator is provided at the bottom of the water tank or inner tub, and a shoe-washing brush is provided at the top of the pulsator. The drive device for driving the rotation of the water tank / inner tub and the pulsator is located at the bottom of the outer casing and at the outer bottom of the water tank / outer tub. The drive device is connected to the water tank / inner tub and the pulsator respectively, so that the shoe-washing structure 5 at the bottom of the first sector plate 2A and / or the second sector plate 2B can rotate with the water tank / inner tub, and the shoe-washing brush at the top of the pulsator can be driven to rotate by the pulsator (the specific structure of this drive device is the same as the drive structure of a conventional pulsator washing machine that drives the inner tub and the pulsator to rotate respectively, and the specific structure of the drive device will not be described in detail here). When washing shoes, the shoes can be washed by the shoe-washing brush rotating at the bottom and the shoe-washing structure 5 rotating at the top, so as to perform all-round friction washing on the shoes moving in the lower and upper parts of the washing water respectively. In shoe washing operation, it is preferable to set the inner tub and the impeller to rotate in the same direction at different speeds or in opposite directions. This is to increase the tumbling effect of the washing water by using different up-and-down agitation methods, thereby increasing the friction between the shoes and the washing water, increasing the movement frequency of the shoes, and thus increasing the friction frequency between the shoes and the shoe washing brush and the shoe washing structure 5, so as to greatly improve the overall shoe washing effect.

[0062] More preferably, the bottom of the first sector plate 2A and the second sector plate 2B are provided with a plurality of shoe-washing structures 5, which are located near the tips of the first sector plate 2A and the second sector plate 2B, so that the shoe-washing structures 5 on different sector plates 2 can be combined into a whole brush body when all sector plates 2 are closed, and the overall shape of the combined brush body is set such that the radial dimension gradually increases from the top of the brush to the bottom of the brush, so that the combined brush body has an unfolded brushing surface. For example, in Figure 1 In the case where there are three sector plates 2, a one-sixth hemispherical brush body is respectively provided at the bottom of the tip of the first sector plate 2A and the two second sector plates 2B. This allows the three shoe washing structures 5 to combine into a hemispherical shoe washing brush after all three sector plates 2 are closed. The radial dimension of this hemispherical shoe washing brush gradually increases from the top to the bottom of the brush. When the hemispherical shoe washing brush rotates, the vortex of washing water near the brush can drive the lighter shoes floating above the washing water to rotate around the hemispherical brush body. This allows the bristles of the hemispherical shoe washing brush to reliably rub and clean the shoes for a long time. Furthermore, the unfolded shape of the shoe washing brush can reliably receive shoes floating from the bottom and can rub against the shoes from any position in its circumference, increasing the brushing angle and greatly optimizing the overall shoe washing effect of the shoe washing equipment.

[0063] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
