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 knob assembly, a locking assembly, and two pins disposed on the side of the tub lid. The two pins are laterally movable and horizontally aligned. The knob assembly is rotatably connected to the tub lid. The knob assembly has a pushing member, with an outwardly protruding pushing end on each opposite side of the pushing member. The pushing member is disposed at the two ends of the two pins that are close to each other. When the lid is closed, both pins move into the locking groove and align with one of the insertion holes. The knob assembly rotates and drives the two pushing ends of the pushing member to rotate closer to one of the pins, so that the two pins are pushed to move separately and insert into one of the insertion holes. The locking assembly can lock the pins when they are inserted into the holes, so that the pins remain inserted into the holes and thus lock the lid. The locking assembly is also configured to allow the lid to rotate relative to the insertion hole by the pin on the locking side when the lid is unlocked on one side, and is also configured to cause the two pins to move closer to each other and move out of the corresponding insertion holes when the lid is unlocked.

[0007] In the preferred embodiment of the above-mentioned washing tub assembly, the knob assembly includes a knob structure and a return torsion spring; the locking assembly includes a pressing structure, two locking plates respectively connected to the pressing structure, a first elastic member, and a second elastic member; the pressing structure is vertically movably connected to the tub lid; the knob structure is rotatably mounted on the pressing structure; the pushing member is located below the pressing structure; the return torsion spring is disposed between the knob structure and the tub lid / pressing structure; the locking plates are vertically arranged and located below the pressing structure; and each locking plate is provided with... The pin has a shaft hole, and an annular groove is provided on the shaft surface. The first elastic member is compressed and disposed at the bottom of the locking piece. There are two second elastic members, one at the end of each pin segment away from the annular groove. The pushing member includes a base connected to the knob structure. Two pushing ends are respectively formed on opposite sides of the base. The radial dimension between the two pushing ends is greater than the radial dimension of the rest of the base. When the lid is not locked, the two pin segments are respectively fitted into one of the shaft holes in a relative manner. The shaft hole is located at the outer end of the annular groove away from the other pin. The two pushing ends face the gap between the two pin segments that are close to each other. When the lid is closed and locked, the knob structure rotates and drives the two pushing ends to push outwards one pin segment, so that the two pin segments move apart and are inserted into the corresponding insertion holes. When the pin is inserted into place, the annular groove aligns with the corresponding shaft hole. The first elastic member can push the locking piece upwards by stretching and rebounding, thus causing the bottom of the shaft hole to lock into the bottom of the annular groove. In order to limit the movement of the two pins closer to each other, the return torsion spring is torsionally deformed when the pushing structure rotates, so that when the torque on the pushing structure disappears, the pushing structure will cause the knob structure to return to rotation by rebound. The two second elastic members are respectively compressed and contracted by the corresponding pins. When the lid is unlocked, the pressing structure is pressed and drives the two locking pieces to move down at the same time. The bottom of the shaft hole exits the annular groove, so that the second elastic members can cause the two pins to move closer to each other by stretching and deformation, and thus exit the corresponding insertion holes.

[0008] In the preferred embodiment of the above-mentioned washing tub assembly, the side of the tub lid is 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 pressing structure is slidably engaged in the first guide groove. The reset torsion spring is provided between the base and the limiting seat. The bottom of each locking piece is provided with a first elastic member. The first elastic member abuts against the locking piece and the bottom of the receiving groove in a compressed manner. A baffle is provided on the pin. The second elastic member abuts against the baffle and the side wall of the receiving groove on the corresponding side. The ends of the two pins that are far apart from each other are aligned with the openings on the corresponding sides or are slidably engaged with the openings on the corresponding sides.

[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 second guide grooves are further provided in the receiving groove, and the second 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 base includes a connecting post and a cam disposed on the connecting post, the connecting post being connected to the bottom of the knob structure, and the pushing end being formed on the cam.

[0012] In the preferred embodiment of the washing tub assembly described above, a mounting post extends downward from the bottom of the cam, a reset torsion spring is sleeved on the mounting post, one end of the reset torsion spring is connected to the mounting post and / or the cam, and the other end of the reset torsion spring is connected to the tub lid.

[0013] In the preferred embodiment of the washing tub assembly described above, side plates are provided at the ends of the pins that are close to each other, and the pushing end pushes the pins outward through the side plates.

[0014] In the preferred embodiment of the above-mentioned washing tub assembly, a guide slope is provided at the opening of the locking groove, and the guide slope can guide the limiting seat into the locking groove.

[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 reliably kept closed by locking it to the opening of the washing tub on both sides. The locking positions on both sides between the lid and the opening not only prevent the lid from leaving the opening but also pivotally connect to the washing tub. This allows the lid to rotate from the closed position to the open position after either locking position is unlocked, based on the pivotal connection between the other locking position and the washing tub. Through this design, the lid can be reliably closed to the opening of the washing tub by 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 having difficulty opening the lid due to the specific orientation of the locking position 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 ensures 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.

[0027] 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.

[0028] 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.

[0029] like Figure 1-6As shown, the washing tub 1 assembly of the present invention is disposed within the outer casing (not shown) of the shoe washing equipment. The washing tub 1 assembly includes a washing tub 1, a lid 2, two locking slots 3, and two locking modules. The figure shows the opening portion of the washing tub 1. 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 locking slots 3 face upwards, and 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. The locking module is set on the side of the lid 2, for example, on the side edge of the lid 2 and / or the edge area of ​​the upper and lower cover plates of the lid 2. The two locking modules are respectively set on opposite sides of the lid 2 along the radial direction. Each locking module includes a knob assembly 4, a locking assembly 5 and two pins 6 installed on the side of the lid 2. The two pins 6 are installed on the side of the lid 2 in a way that allows them to move laterally, and the axes of the two pins 6 are approximately coincident, so that the two pins 6 are horizontally aligned. The knob assembly 4 is rotatably connected to the lid 2. The knob assembly 4 is provided with a pushing member 42. The two opposite sides of the pushing member 42 are respectively provided with an outwardly protruding pushing end 422. The pushing member 42 is located between the two ends of the two pins 6 that are close to each other.When the lid 2 moves close to the bucket opening and closes at the opening position, the side of the lid 2 drives the two pins 6 to move together into the locking groove 3. The ends of the two pins 6 that are far apart from each other are respectively aligned with a socket 31. When it is necessary to lock the lid 2, the knob assembly 4 is turned so that the knob assembly 4 drives the pushing member 42 to rotate. This allows the two pushing ends 422 of the pushing member 42 to move closer to and abut against the ends of the pins 6 by rotation. After further rotation, the two pins 6 can be pushed to move separately and be inserted into their respective aligned sockets 31. The locking assembly 5 can lock the pins 6 when they are inserted into the position so that the pins 6 remain inserted into the sockets 31. The snap-fit ​​mechanism 1 locks the lid 2 onto the washing tub 1, reliably preventing the lid 2 from moving away from the closed position. Furthermore, when the lid 2 is locked on opposite sides, the snap-fit ​​assembly 5 allows the lid 2 to rotate relative to its respective snap-fit ​​holes 31 via two pins 6 on the locking side when one side is unlocked, so that the lid 2 can be pivotally opened based on the remaining locking side after either of the two locking sides is opened. Additionally, when unlocked, the snap-fit ​​assembly 5 causes the two pins 6 to move closer to each other from their respective holes 31, disengaging the snap-fit ​​between the two pins 6 and their respective inserted holes 31, thereby allowing the two pins 6 to move out of the locking groove 3, allowing the locking side of the lid 2 to unlock. Specifically, "the pin 6 being inserted into the aligned socket 31" means that the end of the pin 6 near the socket 31 is reliably moved into the socket 31, so that the pin 6 will not directly dislodge from the socket 31 without being unlocked by the locking assembly 5 when the lid 2 is pulled or twisted. For example, in actual operation, the pin 6 can be inserted into the socket 31 to a set depth.

[0030] 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.

[0031] 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 accessories installed at the bucket opening of the washing tub 1, such as on the balance ring installed at the bucket opening of the washing tub 1.

[0032] Furthermore, the aforementioned locking groove 3 can be a recessed structure integrally formed with the opening of the washing tub 1, or it can be a grooved component fixed within the mounting groove provided at the opening of the washing tub 1. Its specific form is not limited. Figure 2 , 3 The situation shown is that the locking groove 3 is a groove component that is set independently of the washing tub 1.

[0033] 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.

[0034] Continue reading Figure 1-6 In a preferred embodiment, the knob assembly 4 includes a knob structure 41 and a return torsion spring 43, and the locking assembly 5 includes a pressing structure 51, two locking pieces 52 respectively connected to the pressing structure 51, a first elastic member 53, and a second elastic member 54. The pressing structure 51 is vertically movably connected to the bucket lid 2, the knob structure 41 is rotatably disposed on the pressing structure 51, the pushing member 42 is located below the pressing structure 51, the return torsion spring 43 is disposed between the knob structure 41 and the bucket lid 2 / pressing structure 51, the locking pieces 52 are vertically disposed and located below the pressing structure 51, and each locking piece 52 is provided with a shaft hole 521, the radial dimension of which matches the radial dimension of the pin 6. As an example, the pressing structure 51 is a horizontally arranged circular plate-like structure. The tops of the two locking pieces 52 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 521 are respectively provided at the ends of the locking pieces 52 away from the pressing structure 51. The shaft surface of the pin 6 is provided with an annular groove 61. When installed, each section of the pin 6 is freely inserted into a shaft hole 521, so that the two sections of the pin 6, the locking pieces 52, the pressing structure 51, the knob structure 41 and the pushing member 42 can be assembled into one unit. The base 421 includes a connecting post 4211 connected to the bottom of the knob structure 41 and a cam 4212 provided on the connecting post 4211. The cross-sectional shape of the cam 4212 is close to an ellipse (see...). Figure 6The cam 4212 is designed so that its two opposite sides have the largest radial dimensions and the largest outward protrusion. The pushing end 422 is based on the two parts of the cam 4212 with the largest radial dimensions. The first elastic member 53 is provided in a compressed manner at the bottom of at least one locking piece 52. For example, each of the two locking pieces 52 has a first elastic member 53 at its bottom. The first elastic member 53 is provided in a compressed manner between the bottom of the locking piece 52 and the lid 2 so that it can support the locking piece 52 upward by stretching and rebounding, causing the locking piece 52 to be supported against the pin 6 through the bottom of the shaft hole 521. There are two second elastic members 54. Each pin 6 has a second elastic member 54 at the end away from the annular groove 61. The second elastic member 54 is located between the end of the pin 6 away from its annular groove 61 and the lid 2. When the lid 2 is not locked, the two pins 6 are respectively fitted into a shaft hole 521 with their ends aligned with the pushing member 42. The shaft hole 521 is located on the axial surface of the pin 6, offset from the annular groove 61, and located on the outer side of the end of the annular groove 61 away from the other pin 6. The two pushing ends 422 of the cam 4212 are respectively directed toward the gap between the two ends of the two pins 6 that are close to each other, so that the two pins 6 are brought close to each other to the maximum extent, thereby facilitating the smooth insertion of the pins 6 into the locking groove 3 when the lid 2 is closed. Figure 6 The pin 6 and cam 4212 are shown in the unlocked state. At this time, the two pins 6 are close to each other, and the pushing end 422 of cam 4212 is facing the gap between the ends of the two pins 6. Of course, in actual application, the pushing end 422 of cam 4212 can also be tilted towards the gap, as long as it does not push the pins 6 and make it difficult for the pins 6 to enter the locking groove 3.

[0035] Based on the above structure, when the lid 2 is closed, the knob structure 41 rotates and drives the cam 4212 to rotate. The two pushing ends 422 of the cam 4212 move closer to the end of a pin 6 as the cam 4212 rotates, and then push against the pin 6 outwards as the cam 4212 rotates, so that the two pins 6 can move apart from each other. (See...) Figure 6 The straight arrows shown indicate the movement trend of the two pins 6, which causes the ends of the two pins 6 that are far apart to be inserted into the insertion holes 31 respectively. During this process, the locking pieces 52 that are fixed will gradually approach the annular groove 61 on the pins 6 as the pins 6 move. When the pins 6 are inserted into place, the shaft hole 521 on the locking piece 52 and the groove of the annular groove 61 of the pins 6 fitted on the locking piece 52 are aligned with each other, so that the first elastic member 53 can push the locking piece 52 upward by stretching and rebounding, and thus cause the bottom of the shaft hole 521 to be locked in the bottom of the annular groove 61. In this way, the pins 6 are kept in the current state of being locked with the insertion holes 31 by restricting the axial movement of the pins 6, preventing the two pins 6 from falling out of the insertion holes 31 due to moving closer to each other, and thus locking the tub lid 2 to the opening of the washing tub 1.

[0036] After the knob structure 41 is twisted, the end of the return torsion spring 43 connected to the base 421 / cam 4212 is driven to rotate, causing the return torsion spring 43 to twist and deform. After the pin 6 is inserted into the insertion hole 31 and locked by the locking piece 52, the locking action is completed. At this time, the knob structure 41 is released, the torque on the knob structure 41 disappears, and the return torsion spring 43 can cause the pushing structure to drive the knob structure 41 to reset and rotate through the spring, so that it can be twisted when locking the bucket lid 2 next time. Of course, if the knob structure 41 does not need to be automatically reset, the return torsion spring 43 can be omitted. The user only needs to twist the knob structure 41 to lock the bucket lid 2 and then twist the knob structure 41 back to its original position.

[0037] With the lid 2 locked and the end of the pin 6 inserted into the insertion hole 31, the two second elastic members 54 are compressed and contracted by the corresponding pins 6.

[0038] When either side of the lid 2 is unlocked, the pressing structure 51 is pressed and moves vertically downward relative to the lid 2. The two locking pieces 52 are driven downward by the pressing structure 51, causing the bottom of the shaft hole 521 to exit the annular groove 61. The engagement between the shaft hole 521 and the annular groove 61 is disengaged, restoring the shaft hole 521 to be aligned with the groove of the annular groove 61 but not locked in. This releases the restriction on the axial movement of the pin 6, allowing the second elastic member 54 to move closer to each other and exit their respective insertion holes 31 through stretching deformation. The locking state of the lid 2 and the washing tub 1 on that side is released.

[0039] When the lid 2 is unlocked on one side and locked on the other, the engagement between the shaft hole 521 and the bottom of the annular groove 61 can only restrict the axial movement of the pin 6, but cannot restrict the rotation of the pin 6 in the insertion hole 31. Therefore, the lid 2 can be flipped open based on the rotational engagement between the pin 6 and the insertion hole 31.

[0040] like Figures 1 to 3As shown, further, the two opposite sides of the bucket lid 2 are respectively provided with a set of blocking structures 21 and limiting seats 22. The top of the limiting seat 22 is provided with a receiving groove 221 along the vertical direction, and the two opposite sides of the limiting seat 22 are respectively provided with an opening 222 communicating with the receiving groove 221. The opening 222 is provided one-to-one with the pin 6. The locking piece 52, the pushing member 42, the return torsion spring 43, the pin 6, the first elastic member 53 and the second elastic member 54 are all provided in the receiving groove 221. The blocking structure 21 is connected to the bucket lid 2, and the blocking structure 21 is closedly connected to the top of the receiving groove 221 so that the locking piece 52, the pushing member 42, the return torsion spring 43, the pin 6, the first elastic member 53 and the second elastic member 54 can be installed on the bucket lid 2. A first guide groove 211 is vertically provided on the blocking structure 21. The pressing structure 51 is slidably engaged in the first guide groove 211. When the user presses the pressing structure 51, the pressing structure 51 can sink downward along the first guide groove 211. A knob structure 41 is rotatably connected to the top of the pressing structure 51. The pressing structure 51 is provided with a mounting hole, through which the base 421 is connected to the knob structure 41. As an example, the knob structure 41 is a strip-shaped knob rotatably connected to the top of the pressing structure 51. Those skilled in the art can also set the knob to other shapes, such as a knob cap that can rotatably cover the top of the circular pressing member. A mounting post 423 extends downward from the bottom of the cam 4212. A return torsion spring 43 is sleeved on the mounting post 423, and one end of the return torsion spring 43 is connected to the cam 4212 / mounting post 423, and the other end is connected to the bottom of the receiving groove 221. Each locking piece 52 has a first elastic member 53 at its bottom, which is compressed and abuts against the bottom of the locking piece 52 and the receiving groove 221. For example, the bottom of the locking piece 52 has a plug-in post, and the first elastic member 53 is a vertically compressed spring. The top of the spring is sleeved on the plug-in post, and the top end of the spring abuts against the bottom of the locking piece 52, while the bottom end of the spring abuts against the bottom of the receiving groove 221. The ends of two pins 6, which are far apart from each other, are aligned or slidably engaged with the openings 222 on the corresponding sides. A baffle 62 is provided on the pin 6, located between the annular groove 61 and the end of the pin 6 near the opening 222. A second elastic member 54 abuts against the baffle 62 and the side wall of the receiving groove 221 on the corresponding side, so that when the pin 6 extends outward through the opening 222, the second elastic member 54 can be compressed and contracted by the baffle 62 and the side wall of the receiving groove 221. As an example, the second elastic member 54 is a spring sleeved on the pin 6, with both ends of the spring abutting against the side wall of the receiving groove 221 and the baffle 62, respectively. When the lid 2 is closed and locked, the lid 2 moves the limiting seat 22 into the locking groove 3, and the end of the pin 6 is aligned with the insertion hole 31 through the opening 222. At this time, rotating the knob structure 41 and pushing the pin 6 can cause the two sections of the pin 6 to be inserted into the corresponding insertion holes 31 and lock the lid 2.When the lid 2 is unlocked, pressing the pressing structure 51 causes the pin 6 to retract toward the opening 222 and exit the insertion hole 31 under the rebound action of the second elastic member 54, thus unlocking the lid 2 and allowing the limit seat 22 to move out of the locking groove 3.

[0041] Furthermore, the aforementioned receiving groove 221 is also provided with two second guide grooves. The portion of each locking piece 52 near the second guide groove can be slidably engaged in one of the second guide grooves, so that when the pressing structure 51 is pressed down and drives the locking piece 52 to move downward, it can slide down along the second guide groove. The second guide groove limits the locking piece 52, ensuring that the locking piece 52 can be reliably moved and installed vertically.

[0042] In addition, such as Figure 5 As shown, a side plate 63 is provided at the ends of the two pins 6 that are close to each other. The radial dimension of the side plate 63 is larger than the radial dimension of the pin 6, so that the pushing end 422 of the cam 4212 can reliably apply force to the side plate 63 and push the pin 6 in the locked state.

[0043] In addition, the locking groove 3 has a guide slope 32 that slopes from top to bottom into the groove near the groove opening on the side wall of the groove. The guide slope 32 can guide the limiting seat 22 to smoothly align and slide into the locking groove 3 when the lid 2 is closed, ensuring the smooth closure of the lid 2.

[0044] 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.

[0045] More preferably, the washing tub 1 is rotatably configured, such as by rotating the water tank or inner tub. A pulsator is installed at the bottom of the water tank or inner tub, and a shoe-washing brush is installed at the top of the pulsator. A drive device for rotating 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. This drive device is connected to both the inner tub and the pulsator, allowing the shoe-washing component at the bottom of the tub lid 2 to rotate with the inner tub, and the shoe-washing brush at the top of the pulsator to be driven to rotate by the pulsator. The specific structure of this drive device is the same as that of a conventional pulsator washing machine that drives the inner tub and the pulsator to rotate separately; therefore, 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 be used to wash the shoes, allowing for all-around friction washing of the shoes moving in the lower and upper parts of the washing water. In shoe washing operation, it is preferable to set the inner tub and the impeller to rotate at different speeds in the same direction or in opposite directions. This increases the tumbling effect of the washing water by different up-and-down agitation effects, enhances the friction between the shoes and the washing water, increases the movement frequency of the shoes, and thus increases the friction frequency between the shoes and the upper and lower brushes, thereby greatly improving the overall shoe washing effect.

[0046] 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.

[0047] It should be noted that although the structure for locking the lid 2 in the washing tub 1 assembly of the present invention is described as a preferred combination of the limiting seat 22, the blocking structure 21, the knob assembly 4, the locking assembly, and the pin 6, this is not a limitation. Those skilled in the art can increase or decrease the number of components in the washing tub 1 assembly according to actual assembly requirements. For example, if a mounting groove for slidably accommodating the pressing structure 51 is provided vertically on the side of the lid 2, the limiting seat 22 and / or the blocking structure 21 may not be provided. The above-mentioned changes in structural form do not exceed the protection scope of the present invention.

[0048] 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. Two locking modules are respectively disposed on opposite sides of the bucket lid. Each locking module includes a knob assembly, a locking assembly, and two pins disposed on the side of the bucket lid. The two pins are laterally movable and horizontally aligned. The knob assembly is rotatably connected to the bucket lid. The knob assembly is provided with a pushing member, and each of the opposite sides of the pushing member has an outwardly protruding pushing end. The pushing member is disposed between the two close ends of the two pins. With the lid closed, both pins move into the locking slots and align with one of the insertion holes. The knob assembly rotates, causing the two pushing ends of the pushing member to rotate closer to one of the pins, pushing the two pins to move separately and insert them into the insertion holes respectively. The locking assembly can lock the pins when they are inserted into the holes, thus keeping the pins inserted and locking the lid. The locking assembly is further configured to allow the lid to rotate relative to the insertion hole via the pin on the locking side when the lid is unlocked on one side, thereby opening the lid by rotation. It is also configured to cause the two pins to move closer to each other and be removed from the corresponding sockets when unlocked.

2. The washing tub assembly according to claim 1, characterized in that, The knob assembly includes a knob structure and a return torsion spring. The locking assembly includes a pressing structure, two locking plates respectively connected to the pressing structure, a first elastic member, and a second elastic member. The pressing structure is vertically movably connected to the bucket lid. The knob structure is rotatably mounted on the pressing structure. The pushing member is located below the pressing structure. The reset torsion spring is disposed between the knob structure and the bucket lid / pressing structure. The locking plates are vertically arranged and positioned below the pressing 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. The pushing member includes a base connected to the knob structure, and two pushing ends are respectively formed on opposite sides of the base. The radial dimension between the two pushing ends is larger than the radial dimension of the rest of the base. 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. The two pushing ends are respectively facing the gap between the two ends of the two pins that are close to each other. With the lid closed and locked, the knob rotates, causing the two pushing ends to push outwards by a section of the pin, so that the two sections of the pin separate and move into their respective insertion holes. The annular groove aligns with the corresponding shaft hole when the pin is fully inserted. The first elastic member can push the locking piece upward by stretching and rebounding, thereby causing the bottom of the shaft hole to engage with the bottom of the annular groove, in order to restrict the two sections of the pin from moving closer to each other. The reset torsion spring twists and deforms when the pushing member rotates, so that when the torque on the pushing member disappears, it rebounds and causes the pushing member to drive the knob structure to reset and rotate. The two second elastic members are respectively compressed and contracted by the corresponding pins. When the lid is unlocked, the pressing 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 move closer to each other through stretching deformation and thus exit the corresponding insertion hole.

3. The washing tub assembly according to claim 2, characterized in that, The side of the bucket lid is provided with a blocking structure and a limiting seat.
