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 can easily hinder the user from taking the shoes out from the bottom of the barrel, 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 solve 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 ability to take out the shoes after opening.

[0006] This invention provides a washing tub assembly for a shoe washing device. The washing tub assembly includes a washing tub, a tub lid, two locking slots, and two locking modules. The two locking slots are respectively disposed on opposite sides of the opening of the washing tub, with the locking slots facing upwards. Each locking slot has an insertion hole on its two opposite inner sidewalls. The two locking modules are respectively disposed on opposite sides of the tub lid. Each locking module includes a locking component, a pressing component, and two pins disposed on the side of the tub lid. The locking component is connected to the two pins, and each pin is laterally movable. The pressing component includes a pressing structure and a pushing structure connected to the pressing structure. The pressing structure is movably connected to the tub lid, and the pushing structure is connected to the two pins. The proximal ends are aligned with each other, and the width of the pushing structure, at least at the bottom, gradually increases from bottom to top. When the lid is closed, both pins enter the locking groove and are aligned with their respective insertion holes. The pressing structure is pressed and drives the pushing structure to sink between the two pins, so as to cause the two pins to move away from each other and then insert into their respective insertion holes. The locking assembly is configured to keep the two pins engaged with their respective insertion holes to lock the lid, and to allow the lid to rotate relative to the insertion holes via the pins when the lid is unlocked on the opposite side, and to cause the two pins to move out of their respective insertion holes by moving closer to each other when the lid is unlocked.

[0007] In the preferred embodiment of the above-mentioned washing tub assembly, the locking assembly includes a limiting member, a first elastic member, and a second elastic member. The limiting member includes an unlocking structure and two locking pieces respectively connected to the unlocking structure. The unlocking structure is vertically movably connected to the tub lid. The locking pieces are vertically arranged and positioned below the unlocking structure. Each locking piece has a shaft hole, and the shaft surface of the pin has an annular groove. The first elastic member is compressed and positioned at the bottom of the locking piece. There are two second elastic members, with one second elastic member at the end of each pin segment away from the annular groove. When the tub lid is not locked, the two pin segments are respectively fitted into one shaft hole in a relative manner, and the shaft hole is located at the outer end of the annular groove away from the other pin. When the tub lid is closed, the tub lid moves the pin into the locking groove via the locking pieces. The pins respectively... When the lid is locked, the pressing structure is pressed and drives the pushing structure between the two pins. The lower part of the pushing structure is inserted between the two pins, so that the two pins move apart and are inserted into their respective pin holes. The annular grooves move to positions aligned with their respective shaft holes. The first elastic member can push the locking piece upward by stretching and rebounding, thus causing the bottom of the shaft hole to engage with the bottom of the annular groove, so that the two pins remain engaged with their respective pin holes. The two second elastic members are compressed and contracted by their respective pins. When the lid is unlocked, the unlocking structure is pressed and drives the two locking pieces downward simultaneously. The bottom of the shaft hole exits the annular groove, allowing the second elastic members to stretch and deform, causing the two pins to move closer to each other and thus exit their respective pin holes.

[0008] In the preferred embodiment of the above-mentioned washing tub assembly, the side of the tub lid is further provided with a blocking structure and a limiting seat. The top of the limiting seat is provided with a receiving groove along the vertical direction. The two opposite sides of the limiting seat are respectively provided with an opening communicating with the receiving groove. The blocking structure is closed and connected to the top of the receiving groove. The blocking structure is provided with a first guide groove along the vertical direction. The unlocking structure is slidably engaged in the first guide groove. The bottom of each locking piece is provided with a first elastic member. The first elastic member is compressed and abuts against the locking piece and the bottom of the receiving groove. A baffle is provided on the pin. The two ends of the second elastic member abut against the baffle and the side wall of the receiving groove on the corresponding side, respectively. The ends of the two pins that are far apart from each other are aligned with the opening on the corresponding side or are slidably engaged with the opening on the corresponding side.

[0009] In the preferred embodiment of the above-mentioned washing tub assembly, a plug-in post is provided vertically at the bottom of the locking plate, the first elastic member is a spring, and the top end of the spring is sleeved on the plug-in post and abuts against the bottom of the locking plate.

[0010] In the preferred embodiment of the washing tub assembly described above, two vertical guide grooves are further provided in the receiving groove, and the vertical guide grooves are slidably engaged with the locking piece in a one-to-one correspondence.

[0011] In the preferred embodiment of the above-mentioned washing tub assembly, the unlocking structure is provided with a second guide groove along the vertical direction, the pressing structure is disposed in the second guide groove and slides in cooperation with the second guide groove, and the pushing structure is disposed below the unlocking structure.

[0012] In the preferred embodiment of the washing tub assembly described above, the locking module further includes a third elastic member, which is disposed at the bottom of the pushing structure in a compressed manner and is configured to cause the pressing structure to spring back and reset when the pressure on the pressing structure is removed.

[0013] In the preferred embodiment of the above-mentioned washing tub assembly, the ends of the two pins that are close to each other are respectively provided with a slope, and the inclined shape of the slope matches the side shape of the corresponding side of the lower part of the pushing structure.

[0014] In the preferred embodiment of the above-mentioned washing tub assembly, the opening of the locking groove is provided with a guide slope.

[0015] In the preferred embodiment of the above-mentioned washing tub assembly, a shoe washing component is provided with the bottom of the tub lid facing downwards, and when the tub lid is closed, at least a portion of the shoe washing component is located within the washing space of the washing tub.

[0016] With the above technical solution, the lid of the washing tub assembly of the present invention can be locked to the opening of the washing tub on both opposite sides. The locking positions on both sides not only restrict the lid from leaving the opening but also pivotally connect it to the washing tub. This allows the lid to rotate from a closed position to an open position based on the other locking side after unlocking either side. This configuration ensures that the lid can reliably close to the opening of the washing tub through double-sided locking, and can be unlocked by the user from either locking side closest to the user after the washing tub stops rotating. This prevents the user from being unable to open the lid due to its orientation being away from or away from them, and also prevents the lid from obstructing the user's access to shoes due to an unsuitable orientation after opening. This guarantees the ease of opening the lid and the convenience of operation when putting in or taking out shoes.

[0017] Preferably, a shoe-washing component is provided at the bottom of the bucket lid. This design allows the shoe-washing component to enter the interior space of the washing tub after the lid is closed, enabling it to clean lightweight shoes floating on the surface of the washing water. This increases the cleaning angle and improves the overall washing effect. Furthermore, this connection between the shoe-washing component and the bottom of the lid allows it to be moved to the top of the tub each time the lid is opened, greatly enhancing the convenience for users to clean dirt and lint from the component.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, it should 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.

[0030] like Figure 1-4As 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 opening portion of the washing tub 1 is shown in the figure), a lid 2, two locking slots 3, and two locking modules 4. The washing tub 1 is vertically disposed within the outer casing, with its opening facing upwards. A shoe inlet and an outer cover for opening / closing the shoe inlet are provided on the top of the outer casing corresponding to the opening of the washing tub 1. The lid 2 can open or cover the opening of the washing tub 1 to prevent washing water from splashing out during shoe washing. The locking slots 3 are downwardly recessed groove structures located at the top of the opening of the washing tub 1. Two locking slots 3 are respectively disposed on opposite sides of the opening of the washing tub 1 along the radial direction of the washing tub 1, both facing upwards. Each locking slot 3 has a transverse insertion hole 31 on its two opposite inner sidewalls. Each locking slot 3 is respectively provided with a locking module 4. The locking module 4 is located on the side of the lid 2 (the side of the lid 2 may include the side edge of the lid 2 and / or the upper and lower cover plate edge areas of the lid 2). The two locking modules 4 are respectively arranged on opposite sides of the lid 2 along the radial direction. Each locking module 4 includes a locking component 41, a pressing member 42, and two pins 43 respectively connected to the locking component 41 on the side of the lid 2. The two pins 43 are both movably arranged laterally and are approximately flush. The pressing member 42 includes a pressing structure 421 and a pushing structure 422 connected to the pressing structure 421. The pressing structure 421 is movably connected to the side of the lid 2. The pushing structure 422 is arranged downward and above the two pins 43. The width of the pushing structure 422, at least at the bottom, gradually increases from bottom to top (according to...). Figure 3 The orientation, the width dimension of the push structure 422 is... Figure 3The horizontal straight-line distance between the two isosceles sides of the isosceles trapezoidal surface on the front side of the push structure is shown. The gap between the lower end of the push structure 422 and the close-to-each ends of the two pins 43 is vertically aligned. When the lid 2 is closed, both pins 43 are inserted into the locking groove 3, and the far ends of the two pins 43 are aligned with a socket 31. At this time, the pressing structure 421 is pressed, so that the pressed and lowered pressing structure 421 can drive the push structure 422 to sink between the two pins 43. The sinking action of the push structure 422, which increases in width from bottom to top, will cause the two pins 43 to move away from each other and then insert into their respective aligned sockets 31. The locking component 41 is set to enable the two pins 43 to maintain a snap-fit ​​engagement with their respective inserted sockets 31, thereby locking the lid 2 onto the washing tub 1 through the snap-fit ​​engagement of the pins 43 and the sockets 31. The lid 2 is moved from the closed position; and when the lid 2 is locked on both sides, the locking assembly 41 can also allow the lid 2 to rotate relative to its respective locking holes 31 by the two pins 43 on the locking side when one side of the lid 2 is unlocked, so that the lid 2 can be opened by pivoting on the remaining locking side after either of the two locking sides is unlocked; and the locking assembly 41 can also cause the two pins 43 to move closer to each other in the unlocked state and move out of their respective insertion holes 31, so that the locking engagement between the two pins 43 and their respective locking holes 31 is disengaged, thereby allowing the pins 43 to be moved out of the locking groove 3, allowing the locking side of the lid 2 to be unlocked.

[0031] In the above embodiments, 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 tub lid 2 is disposed at the opening of the water-holding tub and is used to cover or open the opening of the water-holding tub. When the water-holding tub is rotatable, the tub lid 2 rotates 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 tub lid 2 is disposed at the opening of the inner tub and is used to cover or open the opening of the inner tub. When the inner tub is rotatable, the tub lid 2 rotates synchronously with the inner tub.

[0032] In addition, the above-mentioned bucket lid 2 being set at the bucket opening of the washing tub 1 specifically means that the bucket lid 2 is set near the bucket opening of the washing tub 1 in a position that does not interfere with the normal operation of the washing tub 1 or obstruct the normal handling of shoes, such as the top of the bucket opening of the washing tub 1, the upper inside of the bucket opening of the washing tub 1, or on the accessories installed at the bucket opening of the washing tub 1 (such as the balance ring installed at the bucket opening of the washing tub 1).

[0033] Furthermore, the locking groove 3 can be a groove structure integrally formed with the opening of the washing tub 1, or it can be a groove component fixed in the mounting groove set in the opening of the washing tub 1. Its specific form is not limited.

[0034] The above design allows the user to reliably secure the lid 2 to the opening of the washing tub 1 by locking both sides of the lid 2 when closing it. This satisfies the basic water-blocking requirement of the lid 2 while preventing noise caused by the lid 2 colliding with the opening of the tub 1 due to vibrations during shoe washing. Simultaneously, the user can unlock either side and rotate the lid 2 to open it, ensuring smooth opening regardless of which side is closest to the user. Furthermore, the opened lid 2 will not obstruct the user's path to the tub opening, thus preventing the user from taking shoes in or out. Additionally, the lid 2 can be removed from the washing tub 1 by unlocking both sides, facilitating maintenance, repair, or cleaning of the washing tub 1 and / or the lid 2 after removal.

[0035] like Figure 1-4 As shown in Figures 6 and 7, in a preferred embodiment, the locking assembly 41 includes a limiting member 411, a first elastic member 412, and a second elastic member 413. The limiting member 411 includes an unlocking structure 4111 and two locking pieces 4112 respectively connected to the unlocking structure 4111. The unlocking structure 4111 is vertically movably connected to the bucket lid 2. The locking pieces 4112 are vertically arranged and located below the unlocking structure 4111. Each locking piece 4112 is provided with a shaft hole 4113. The shaft surface of the pin 43 is provided with an annular groove 431. The radial dimension of the shaft hole 4113 matches the radial dimension of the pin 43 and is smaller than the radial dimension of the surface where the bottom of the annular groove 431 is located. As an example, the unlocking structure 4111 is a horizontally arranged plate-like structure. The tops of the two locking pieces 4112 are respectively connected to the side ends of the plate-like structure, forming a plate similar to an inverted U-shape together with the plate-like structure. The shaft holes 4113 are respectively provided at the ends of the locking pieces 4112 away from the unlocking structure 4111 (see...). Figure 6 In the installed state, each pin 43 is freely inserted into a shaft hole 4113, and the two pins 43 are assembled with the locking piece 4112 as a whole. The aforementioned first elastic member 412 is provided in a compressed manner at the bottom of at least one locking piece 4112. For example, the bottom of each of the two locking pieces 4112 is provided with a first elastic member 412. The first elastic member 412 is provided in a compressed manner between the bottom of each locking piece 4112 and the bucket lid 2, so that it can support the two locking pieces 4112 upward by expanding and rebounding respectively, so that the locking pieces 4112 are supported against the pin 43 through the bottom of the shaft hole 4113. There are two second elastic members 413. Each pin 43 is provided with a second elastic member 413 at the end away from the annular groove 431. The second elastic member 413 is provided between the end of the pin 43 away from its annular groove 431 and the bucket lid 2.

[0036] Based on the above configuration, when the lid 2 is not locked, the pushing structure 422 is above the gap between the two pins 43 or has not been pushed down into place. The two pins 43 are respectively fitted into a shaft hole 4113 in a relative manner. The shaft hole 4113 on each locking piece 4112 is located on the shaft surface of the pin 43 it is fitted with, offset from the annular groove 431 on the pin 43 it is fitted with, and located on the outer side of the annular groove 431 of the pin 43 it is fitted with, away from the other pin 43 (e.g., Figure 3 (as shown in the image);

[0037] With the lid 2 closed and locked, the pressing structure 421 is pressed down and drives the pushing structure 422 to insert between the close ends of the two pins 43. This causes the two pins 43 to separate and move apart through a gradually widening shape, thus causing the far ends of each pin 43 to gradually approach their respective aligned insertion holes 31, until both pins 43 are inserted and locked into their respective aligned insertion holes 31. During this process, the separation and movement of the two pins 43 also causes their respective annular grooves 431 to gradually approach the shaft holes 4113 on their respective locking plates 4112. When the pins are reliably inserted into their respective aligned insertion holes 31, the openings of the annular grooves 431 on each pin 43 can move precisely to a position aligned with their respective shaft holes 4113. This allows the first elastic member 412 to push the locking piece 4112 upwards through a springback motion, thereby causing the bottom of the shaft hole 4113 to engage with the bottom of the annular groove 431. This restricts the axial movement of the two pins 43, maintaining their current engagement with their respective insertion holes 31 and preventing them from dislodging from the insertion holes 31 due to movement closer together. Consequently, the lid 2 is locked to the opening of the washing tub 1. With the lid 2 locked and the ends of the pins 43 engaged in the insertion holes 31, the two second elastic members 413 are compressed and contracted by their corresponding pins 43.

[0038] When either side of the lid 2 is unlocked, the unlocking structure 4111 is pressed and moves vertically downward relative to the lid 2. The two locking pieces 4112 are driven downward by the unlocking structure 4111, causing the bottom of the shaft hole 4113 to disengage from its respective annular groove 431. The engagement between the shaft hole 4113 and the annular groove 431 is disengaged, restoring the shaft hole 4113 to be aligned with the groove of the annular groove 431 but not engaged. This releases the restriction on the axial movement of the pin 43, allowing the second elastic member 413 to move closer to each other through stretching deformation. This causes the two pins 43 to move closer to each other and then disengage from their respective corresponding insertion holes 31, thus releasing the locking state between the lid 2 and the washing tub 1 on that side.

[0039] When the lid 2 is unlocked on one side and locked on the other, the locking engagement between the pin 43 on the locking side and the socket 31 can only restrict the pin 43 from leaving the washing tub 1, but cannot restrict the pin 43 from rotating in the socket 31. Therefore, the lid 2 can be flipped open based on the rotational engagement between the pin 43 on the locking side and the socket 31.

[0040] Continue reading Figure 1-6 Furthermore, the bucket lid 2 is provided with a set of blocking structures 6 and limiting seats 5 on its two opposite sides. The top of the limiting seat 5 has a vertically oriented receiving groove 51 with an opening 52 facing upwards. Each of the two opposite sides of the limiting seat 5 has an opening 52 communicating with the receiving groove 51. The two openings 52 correspond one-to-one with the pin 43. The pressing member 42, the limiting member 411, the pin 43, the first elastic member 412, and the second elastic member 413 are all located within the receiving groove 51. The blocking structure 6 is connected to the bucket lid 2, such as... Figure 1 The ear structure shown is integrally connected to the lid 2, and the blocking structure 6 is closedly connected to the top of the receiving groove 51 so that the pressing member 42, the limiting member 411, the pin 43, the first elastic member 412 and the second elastic member 413 are encapsulated in the limiting seat 5 and installed to the side of the lid 2. Specifically, the blocking structure 6 is provided with a first guide groove 61 vertically, and the unlocking structure 4111 is slidably locked in the first guide groove 61. When the user presses the unlocking structure 4111, the unlocking structure 4111 can sink down along the first guide groove 61. Each locking piece 4112 has a first elastic member 412 at its bottom, and the first elastic member 412 abuts against the bottom of the receiving groove 51 in a compressed manner. As an example, the bottom of the locking piece 4112 is provided with a first insertion post, and the first elastic member 412 is a spring that is compressed vertically. The top of the spring is sleeved on the first insertion post, and the top end of the spring abuts against the bottom of the locking piece 4112, while the bottom end of the spring abuts against the bottom of the receiving groove 51. The ends of the two pins 43 that are far apart from each other are aligned or slidably engaged with the openings 52 on the corresponding sides. A baffle 432 is provided on the pin 43, which is located between the annular groove 431 and the end of the pin 43 near the opening 52. The second elastic member 413 abuts against the baffle 432 and the side wall of the receiving groove 51 on the corresponding side, so that when the pin 43 extends outward through the opening 52, the second elastic member 413 can be squeezed and contracted by the baffle 432 and the side wall of the receiving groove 51. As an example, the second elastic member 413 is a spring sleeved on the pin 43, with the two ends of the spring abutting against the side wall of the receiving groove 51 and the baffle 432, respectively.

[0041] The unlocking structure 4111 has a second guide groove 4111A vertically arranged along its upper edge. The pressing structure 421 is disposed within the second guide groove 4111A and slides within it. The pushing structure 422 is disposed below the unlocking structure 4111 and can prevent the pressing structure 421 from moving upward from the second guide groove 4111A by abutting against the lower side of the unlocking structure 4111. The locking module 4 also includes a third elastic member 44, which is disposed in a compressed manner at the bottom of the pushing structure 422 and is configured to cause the pressing structure 421 to spring back to its original position when the pressure on the pressing structure 421 is removed. As an example, the third elastic member 44 is a spring. The bottom of the pushing structure 422 extends downward and is provided with a second insertion post 423. The top end of the spring is sleeved on the second insertion post 423 and abuts against the bottom of the pushing structure 422. The bottom end of the spring abuts against the bottom of the receiving groove 51. In its natural state, the spring pushes the pushing structure 422 upward by stretching and rebounding, causing the pressing structure 421 to be in the maximum extended position.

[0042] With the lid 2 closed and locked, the lid 2 is closed to the bucket opening position, the limiting seat 5 moves into the locking groove 3, and pressing down the pressing structure 421 causes the two pins 43 to separate from each other and be inserted into the corresponding insertion holes 31. The shaft hole 4113 on the locking piece 4112 engages with the annular groove 431, locking the pins 43. Releasing the pressing structure 421 causes the third elastic member 44 to cause the pushing structure 422 to drive the pressing structure 421 back to the maximum extended position.

[0043] With the lid 2 unlocked, pressing down on the unlocking mechanism 4111 causes the second elastic member 413 on the unlocking side to cause the pin 43 to exit from the socket 31.

[0044] Of course, in an alternative scenario, the third elastic member 44 may not be provided below the pushing structure 422. In this case, when one side of the lid 2 is unlocked and the two pins 43 move closer to each other, the continuously moving pins 43 will push the pushing structure 422 upward, causing the pushing structure 422 to move upward and thus reset the pressing structure 421, so that the pressing structure 421 can be pressed down again when the next side is locked.

[0045] In another alternative scenario, the second guide groove 4111A can also be provided on the blocking structure 6, so that the pressing structure 421 and the unlocking structure 4111 slide in cooperation with the blocking structure 6 respectively, and the pressing structure 421 and the unlocking structure 4111 are set as two separate buttons. In this case, those skilled in the art can adjust the specific shape of the unlocking structure 4111 according to the pressing requirements and the setting requirements of the pressing structure 421, such as setting the rectangular plate-shaped unlocking structure 4111 as a strip.

[0046] Furthermore, the aforementioned receiving groove 51 is also provided with two vertical guide grooves 511. The locking piece 4112 and the vertical guide grooves 511 are arranged in a one-to-one correspondence. The part of the locking piece 4112 near the vertical guide groove 511 is slidably engaged in the vertical guide groove 511 so that when the unlocking structure 4111 is pressed down and the locking piece 4112 moves downward, it can slide down along the vertical guide groove 511. The vertical guide groove 511 limits the locking piece 4112, ensuring that the locking piece 4112 can be reliably moved and installed vertically.

[0047] Preferably, such as Figure 3 , 7 As shown, the pushing structure 422 is symmetrically arranged, and the two sides of the lower part of the pushing structure 422 are two inclined surfaces that gradually converge from top to bottom. The ends of the two pins 43 that are close to each other are respectively provided with a slope 433. The inclination trend of the slope 433 is the same as the inclination trend of the lower side of the pushing structure 422 that it is close to, so as to guide the pushing structure 422 to be inserted between the two pins 43 and improve the smoothness of the pressing and unlocking action.

[0048] Furthermore, when the lid 2 is locked, the side face of the limiting seat 5 (the outer side of the side wall where the opening 52 is located) abuts against the inner side wall of the locking groove 3 (the inner side of the groove wall where the insertion hole 31 is located) to stably lock the limiting seat 5 in the locking groove 3, further improving the locking stability of the lid 2. Additionally, the side wall of the locking groove 3 near the groove opening is provided with a guide slope 32 that slopes downwards into the groove. This guide slope 32 guides the limiting seat 5 to smoothly align and slide into the locking groove 3 when the lid 2 is closed, ensuring a smooth closure of the lid 2.

[0049] Preferably, the bottom of the bucket lid 2 of the present invention is provided with a shoe washing component facing downwards. When the bucket lid 2 is closed, at least a portion of the shoe washing component is located in the washing space of the washing bucket 1 so as to reliably clean the lightweight shoes floating and moving on the upper part of the washing water in the bucket.

[0050] 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 component at the bottom of the tub lid 2 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 shoe-washing brush rotating at the bottom and the shoe-washing component rotating at the top can wash the shoes from both above and below, so as to perform all-round friction washing on the shoes that move in the lower and upper parts of the washing water respectively. In shoe washing operation, it is preferable to set the water tank / inner tank and the impeller to rotate in the same direction at different speeds or in opposite directions. This will increase the tumbling effect of the washing water by different up-and-down agitation effects, improve the friction between the shoes and the washing water, increase the movement frequency of the shoes, and thus increase the friction frequency between the shoes and the upper and lower brushes, thereby greatly improving the overall shoe washing effect.

[0051] More preferably, the shoe washing component is also configured as a shoe washing brush, and both the shoe washing brush and the shoe washing brush on top of the impeller are configured with radial dimensions that gradually increase from the top to the bottom of the brush, so that each of the two shoe washing brushes has an unfolded brushing surface. For example, both shoe washing brushes are configured as hemispherical brush bodies. When the upper and lower hemispherical brush bodies rotate, the vortex of washing water near the upper hemispherical brush body can drive the lighter shoes floating above the washing water to rotate around the hemispherical brush body, and the vortex of washing water near the lower hemispherical brush body can drive the heavier shoes moving below the washing water to rotate around the hemispherical brush body, so that all the shoes in the tub can be reliably cleaned by the unfolded bristles of the two hemispherical brush bodies arranged one above the other for a long time. In addition, the unfolded hemispherical brush body can also reliably receive shoes floating from opposite directions, 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.

[0052] It should be noted that although the structure for locking the tub lid 2 in the washing tub assembly of the present invention is described as a preferred combination of the limiting seat 5, the blocking structure 6, the pressing member 42, the locking component 41, and the pin 43, this is not a limitation. Those skilled in the art can increase or decrease the number of washing tub components according to actual assembly needs. For example, if a mounting groove for slidably accommodating the unlocking structure 4111 is provided vertically on the side of the tub lid 2, the limiting seat 5 and / or the blocking structure 6 may not be provided. The above-mentioned changes in structural form do not exceed the protection scope of the present invention.

[0053] 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.

Claims

1. A washing tub assembly for a shoe washing device, characterized in that, The washing tub assembly includes a washing tub, a tub lid, two locking slots, and two locking modules. The two locking slots are respectively disposed on opposite sides of the opening of the washing tub, with the locking slots facing upwards, and each of the two opposite inner sidewalls of the locking slots is provided with an insertion hole. The two locking modules are respectively disposed on opposite sides of the bucket lid. Each locking module includes a locking component, a pressing component, and two pins disposed on the side of the bucket lid. The locking component is connected to the two pin segments respectively, and each pin segment is movably lateral. The pressing component includes a pressing structure and a pushing structure connected to the pressing structure. The pressing structure is movably connected to the bucket lid. The pushing structure is aligned with the proximal ends of the two pins. The width of the pushing structure, at least at its lower part, gradually increases from bottom to top. With the lid closed, both pins enter the locking grooves and align with their respective insertion holes. The pressing mechanism is pressed, causing the pushing mechanism to sink between the two pins, thus moving the two pins away from each other and allowing them to insert into their corresponding insertion holes. The locking component is configured to keep the two pins engaged with their corresponding sockets, thereby locking the bucket lid. The lid is able to rotate relative to the mortise via the pin when unlocked on the opposite side, and It can also cause the two pins to move out of the corresponding holes by moving closer to each other when the lid is unlocked; The locking component includes a limiting member, a first elastic member, and a second elastic member. The limiting component includes an unlocking structure and two locking plates respectively connected to the unlocking structure. The unlocking mechanism is vertically movably connected to the bucket lid. The locking plates are vertically arranged and positioned below the unlocking structure. Each locking plate has a shaft hole, and the shaft surface of the pin has an annular groove. The first elastic member is disposed at the bottom of the locking piece in a compressed manner. The number of the second elastic members is two, with one second elastic member provided at the end of each pin shaft away from the annular groove. When the lid is not locked, the two pins are respectively fitted into one of the shaft holes in a relative manner, and the shaft hole is located on the outer end of the annular groove away from the other pin. With the lid closed, the lid, via the locking tab, moves the pins into the locking grooves, and the pins align with their respective insertion holes. With the lid locked, the pressing mechanism is pressed, causing the pushing mechanism to enter between the two pin sections. The lower part of the pushing mechanism inserts between the two pin sections, causing them to separate and move, thus inserting into their respective insertion holes. The annular grooves move to positions aligned with their respective shaft holes. The first elastic member can push the locking piece upwards by stretching and rebounding, thereby causing the bottom of the shaft hole to engage with the bottom of the annular groove, so that the two pins remain engaged with their corresponding insertion holes. The two second elastic members are compressed and contracted by their corresponding pins. When the lid is unlocked, the unlocking structure is pressed and causes the two locking pieces to move down simultaneously. The bottom of the shaft hole exits the annular groove, allowing the second elastic member to stretch and deform to move the two pins closer to each other and thus exit their respective insertion holes.
