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 of the two inner sidewalls of the locking slots has an insertion hole. The two locking modules are respectively disposed on opposite sides of the tub lid. Each locking module includes a locking component disposed on the side of the tub lid and two pins respectively connected to the locking component. The two pins are movably disposed laterally. The locking component is configured to cause the two pins to move together into the locking slots and lock into the two insertion holes in a way that allows them to move apart when the tub lid is closed, thereby locking the tub lid. It is also configured to allow the tub lid to rotate relative to the insertion holes via the pins when the opposite side of the tub lid is unlocked, and to cause the two pins to move closer to each other and move out of the corresponding insertion holes when the tub lid is unlocked.

[0007] In the preferred embodiment of the aforementioned washing tub assembly, the locking assembly includes a pressing member, a first elastic member, and a second elastic member. A locking pin is also vertically disposed within the locking groove. The pressing member includes a pressing structure and two locking pieces respectively connected to the pressing structure. The pressing structure is vertically movably connected to the tub lid. The locking pieces are vertically disposed below the pressing structure. Each locking piece has a shaft hole. An annular groove is provided on the shaft surface of the pin. The first elastic member is compressed and disposed at the bottom of the locking piece. There are two second elastic members, with one second elastic member disposed at the end of each pin segment away from the annular groove. The locking pin is upward-facing and aligned between the two pin segments. The width of at least the upper part of the locking pin gradually increases from top to bottom. 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 far from the annular groove. When the lid is closed, the lid moves the pin closer to the locking groove via the locking piece at the outer end of the other pin. The upper part of the locking pin is inserted between the two pin segments so that when the two pin segments sink, they separate and move apart, thereby causing each pin segment to be inserted into the corresponding insertion hole and each annular groove to be aligned with the corresponding shaft hole. The first elastic member can push the locking piece upward by stretching and rebounding, thus causing the bottom of the shaft hole to be locked at the bottom of the annular groove, thereby restricting the two pin segments from moving closer to each other. The two second elastic members are 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 downward simultaneously. The bottom of the shaft hole exits the annular groove, allowing the second elastic members to move closer to each other by stretching and deforming, 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, and the bottom of the limiting seat is provided with a slot communicating with the receiving groove. 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 guide groove along the vertical direction. The pressing structure is slidably engaged in the guide groove. 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. The width of the slot is not less than the maximum width of the locking pin, and the slot is aligned with the two pins and the locking pin respectively.

[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 end faces of the two pins that are close to each other are respectively set as slopes, and the inclined shape of the slopes matches the side shape of the corresponding side of the locking pin.

[0012] In the preferred embodiment of the above-mentioned washing tub assembly, the width of the locking pin gradually increases from the top to the middle, and the lowest position of the insertion hole is not lower than the middle of the locking pin.

[0013] In the preferred embodiment of the above-mentioned washing tub assembly, when the tub lid is locked, the side end face of the limiting seat abuts against the inner side wall of the locking groove.

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

[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 1-4As 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 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 4 are respectively arranged on opposite sides of the lid 2 along the radial direction. Each locking module 4 includes a locking component 41 located on the side of the lid 2 and two pins 42 connected to the locking component 41. The two pins 42 are movably arranged laterally and are approximately flush. When the lid 2 moves close to the opening and closes at the opening position, the locking component 41 is configured to cause the two pins 42 to move into the locking slot 3 together and cause the two pins 42 to move laterally outward in a way that separates from each other. The ends of the two pins 42 that are far apart from each other are close to an insertion hole 31. When the lid 2 is closed in place, the two pins 42... The ends of the pins 42 that are far apart from each other are moved into and locked into the two sockets 31, so that the tub lid 2 is locked onto the washing tub 1 by the locking engagement of the pins 42 and the sockets 31, and the tub lid 2 is restricted from being moved out of the closed position; and when the opposite sides of the tub lid 2 are locked, the locking assembly 41 can also allow the tub lid 2 to rotate relative to the sockets 31 by means of the two pins 42 on the locking side when one side of the tub lid 2 is unlocked, so that the tub lid 2 can be pivoted open based on the remaining locking side after either of the two locking sides of the tub lid 2 is opened; and when the tub lid 2 is unlocked, the locking assembly 41 can also cause the two pins 42 to move out of the corresponding sockets 31 by moving closer to each other, so that the locking engagement between the two pins 42 and the sockets 31 they are locked into is disengaged, so that the pins 42 can be moved out of the locking grooves 3, allowing the locking side of the tub lid 2 to be unlocked.

[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 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).

[0032] 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.

[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] like Figure 1-6As shown, in a preferred embodiment, the locking assembly 41 includes a pressing member 411, a first elastic member 412, and a second elastic member 413. A locking pin 32 is also vertically arranged in the locking groove 3. The pressing member 411 includes a pressing structure 4111 and two locking pieces 4112 respectively connected to the pressing structure 4111. The pressing structure 4111 is vertically movably connected to the bucket lid 2. The locking pieces 4112 are vertically arranged and positioned below the pressing structure 4111. Each locking piece 4112 has a shaft hole 4113, the radial dimension of which matches the radial dimension of the pin 42. As an example, the pressing 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 located at the ends of the locking pieces 4112 away from the pressing structure 4111. The pin 42 has an annular groove 421 on its shaft surface. When installed, each pin 42 segment freely passes through a shaft hole 4113, and the two pins 42 at both ends 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, each of the two locking pieces 4112 has a first elastic member 412 at its bottom. The first elastic member 412 is provided in a compressed manner between the bottom of the locking piece 4112 and the lid 2, so that it can support the locking piece 4112 upward by expanding and rebounding, causing the locking piece 4112 to be supported against the pin 42 through the bottom of the shaft hole 4113. There are two second elastic members 413. Each pin 42 segment has a second elastic member 413 at the end away from the annular groove 421. The second elastic member 413 is located between the end of the pin 42 away from its annular groove 421 and the lid 2. The locking pin 32, which is disposed in the locking groove 3, is positioned upward and aligned between the two sections of the pin 42. The width of the upper portion of the locking pin 32 corresponds to the distance between the ends of the two pins 42 that are close to each other. Figure 3 The dimension d) shown in the figure gradually increases from top to bottom so that the width of the locking pin 32 gradually increases from its top to its middle. For example, the locking pin 32 shown in the figure is an example of the case where the width of the locking pin 32 gradually increases from the top to the middle. In this case, the lowest position of the insertion hole 31 is not lower than the middle of the locking pin 32, so that the two pins 42 can be pushed into the corresponding insertion hole 31 by sliding at most to the maximum width position of the locking pin 32. When the lid 2 is not locked, the two pins 42 are respectively fitted into a shaft hole 4113 in a relative manner, and the shaft hole 4113 is located on the axial surface of the pin 42, offset from the annular groove 421, and located on the outer side of the annular groove 421 away from the other pin 42.

[0035] Based on the above structure, when the lid 2 is closed, the lid 2 drives the pin 42 to move closer to the locking groove 3 via the locking piece 4112. The upper part of the locking pin 32 is inserted between the two pins 42, so that when the two pins 42 sink, the gradually changing width shape causes the two pins 42 to separate and move apart. This causes the ends of each pin 42 that are far apart to gradually move closer to the position of the insertion hole 31 during the process of sinking into the locking groove 3, until the lid 2 is closed in place, and the two pins 42 at both ends are inserted into and locked into the corresponding insertion holes 31. During this process, the separation and movement of the two pins 42 at both ends will also drive the pins 42 at both ends to move closer to the position of the insertion hole 31. The annular groove 421 gradually approaches its respective shaft hole 4113 until the opening of the annular groove 421 is exactly aligned with its corresponding shaft hole 4113 when the lid 2 is closed. This allows the first elastic member 412 to push the locking piece 4112 upwards through its expansion and rebound, thereby causing the bottom of the shaft hole 4113 to engage with the bottom of the annular groove 421. This restricts the axial movement of the two pins 42, maintaining the pins 42 in their current engaged state with the insertion hole 31 and preventing them from dislodging from the insertion hole 31 due to their proximity. This locks the lid 2 at the opening of the washing tub 1. With the lid 2 locked and the pins 42 engaged with the insertion hole 31, the two second elastic members 413 are compressed and contracted by their corresponding pins 42.

[0036] When either side of the lid 2 is unlocked, the pressing structure 4111 is pressed and moves vertically downward relative to the lid 2. The two locking pieces 4112 are driven downward by the pressing structure 4111, causing the bottom of the shaft hole 4113 to exit the annular groove 421. The locking engagement between the shaft hole 4113 and the annular groove 421 is disengaged, restoring the shaft hole 4113 to be aligned with the groove of the annular groove 421 but not locked in. This releases the restriction on the axial movement of the pin 42, allowing the second elastic member 413 to move closer to each other through stretching deformation. The two pins 42 move closer to each other by abutting against the inclined side of the locking pin 32, thereby exiting their respective insertion holes 31 and popping upward from the bottom of the locking groove 3. The locking state of the lid 2 and the washing tub 1 on that side is released.

[0037] When the lid 2 is unlocked on one side and locked on the other, the engagement between the shaft hole 4113 and the bottom of the annular groove 421 can only restrict the axial movement of the pin 42, but cannot restrict the rotation of the pin 42 in the insertion hole 31. Therefore, the lid 2 can be flipped open based on the rotational engagement between the pin 42 and the insertion hole 31.

[0038] Continue reading Figure 2-5Furthermore, the bucket lid 2 is provided with a set of blocking structures 21 and limiting seats 22 on its two opposite sides. The top of the limiting seat 22 has a vertically oriented receiving groove 221, and the bottom of the limiting seat 22 has a slot 222 communicating with the receiving groove 221. The two opposite sides of the limiting seat 22 each have an opening 223 communicating with the receiving groove 221. Each opening 223 corresponds to a pin 42. The pressing member 411, pin 42, first elastic member 412, and second elastic member 413 are all disposed within the receiving groove 221. The blocking structure 21 is connected to the bucket lid 2 and is closedly connected to the top of the receiving groove 221, so that the pressing member 411, pin 42, first elastic member 412, and second elastic member 413 can be installed on the bucket lid 2. A guide groove 211 is vertically arranged on the blocking structure 21. The pressing structure 4111 is slidably engaged in the guide groove 211. When the user presses the pressing structure 4111, it sinks downward along the guide groove 211. Each locking piece 4112 has a first elastic member 412 at its bottom. The first elastic member 412 is compressed and abuts against the bottom of the locking piece 4112 and the receiving groove 221. As an example, the bottom of the locking piece 4112 is provided with a plug post 4114. The first elastic member 412 is a spring that is compressed vertically. The top of the spring is sleeved on the plug post 4114, 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 221. Two pins 42, with their ends facing away from each other, are aligned or slidably engaged with openings 223 on corresponding sides. A baffle 422 is provided on each pin 42, located between the annular groove 421 and the end of the pin 42 near the opening 223. A second elastic member 413 abuts against the baffle 422 and the side wall of the corresponding receiving groove 221, so that when the pin 42 extends outward through the opening 223, the second elastic member 413 can be compressed and contracted by the baffle 422 and the side wall of the receiving groove 221. As an example, the second elastic member 413 is a spring sleeved on the pin 42, with its two ends abutting against the side wall of the receiving groove 221 and the baffle 422, respectively. The width of the slot 222 is not less than the maximum width of the locking pin 32, and the locking pin 32 is aligned with the two pins 42 via the slot 222. When the lid 2 is closed and locked, the lid 2 moves the limiting seat 22 into the locking groove 3, and the locking pin 32 inserts into the slot 222 and between the two pins 42, so that the two pins 42 separate from each other as the limiting seat 22 moves toward the bottom of the locking groove 3 and extend outward through their respective openings 223, so that they are inserted into the insertion hole 31 when the lid 2 is closed. When the lid 2 is unlocked, the second elastic member 413 on the unlocking side causes the pin 42 to exit from the insertion hole 31 and causes the limiting seat 22 to pop upward from the locking groove 3.

[0039] Furthermore, the aforementioned receiving groove 221 is also provided with two vertical guide grooves 2211. The portion of each locking piece 4112 near the vertical guide groove 2211 can be slidably engaged in one of the vertical guide grooves 2211, so that when the pressing structure 4111 is pressed down and drives the locking piece 4112 to move downward, it can slide down along the vertical guide groove 2211. The vertical guide groove 2211 limits the locking piece 4112, ensuring that the locking piece 4112 can be reliably moved and installed vertically.

[0040] In addition, such as Figure 6 As shown, the end faces of the two pins 42 that are close to each other are respectively set as slopes 423, and the inclined shape of the slope 423 matches the inclined shape of the side of the locking pin 32 that it is close to. When the locking pin 32 forms a slope 423 that gradually slopes outward from top to bottom on two opposite sides due to the gradual change in width, the inclined direction of the slope 423 at the end of the pin 42 is set to be approximately inward from top to bottom so as to match the slope of the side of the locking pin 32. Furthermore, the slope 423 at the end of the pin 42 is set so as not to affect the rotation of the pin 42 relative to the insertion hole 31, so as not to interfere with the pivoting opening of the lid 2 when unlocking on one side. For example, the slope 423 at the end of the pin 42 can be specifically set as an outwardly convex arc-shaped slope 423 so as to facilitate the insertion of the locking pin 32 between the two pins 42 while ensuring the smooth rotation of the pin 42.

[0041] Furthermore, when the lid 2 is locked, the side face of the limiting seat 22 (the outer side of the side wall where the opening 223 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 22 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 33 that slopes from top to bottom into the groove. This guide slope 33 guides the limiting seat 22 to smoothly align and slide into the locking groove 3 when the lid 2 is closed, ensuring a smooth closure of the lid 2.

[0042] Preferably, the bottom of the bucket lid 2 of the present invention is provided with a shoe washing component 5 facing downward. When the bucket lid 2 is closed, at least a portion of the shoe washing component 5 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.

[0043] 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 inner tub and the pulsator respectively, so that the shoe-washing component 5 at the bottom of the tub lid 2 can rotate with the 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 component 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 upper and lower brushes, which greatly improves the overall shoe washing effect.

[0044] More preferably, the shoe washing component 5 is also configured as a shoe washing brush, and both the shoe washing brush and the shoe washing brush on the top of the impeller are configured such that their radial dimensions gradually increase from the tip of the brush to the bottom of the brush (see...). Figure 2 The shape of the shoe washing component 5 (as shown in the example) is designed 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. This ensures that all shoes in the tub can be reliably cleaned by the unfolded bristles of the two hemispherical brush bodies, one above the other, for a long time. Furthermore, the unfolded hemispherical brush body can 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.

[0045] 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 22, the blocking structure 21, the locking component 41, and the pin 42, 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 the side of the tub lid 2 is provided with a vertical mounting groove that can slidably accommodate the pressing structure 4111, 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.

[0046] 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 of a shoe washing apparatus, characterized by, 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 disposed on the side of the bucket lid and two pins respectively connected to the locking component. The two pins are movably disposed laterally. The locking assembly is configured to cause both pins to move together into the locking groove and, in a manner that allows them to move separately from each other, engage with the two insertion holes, thereby locking the lid. It also allows the lid to rotate relative to the mortise via the pin when unlocked on the opposite side of the lid, and It can also cause the two pins to move closer to each other and be removed from the corresponding sockets when the device is unlocked; The locking assembly includes a pressing member, a first elastic member, and a second elastic member. A locking pin is also vertically disposed within the locking groove. The pressing component includes a pressing structure and two locking pieces respectively connected to the pressing structure. The pressing structure is vertically movably connected to the bucket lid. 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 locking pin is positioned upwards and aligned between the two pin sections, and the width of the locking pin, at least at its upper part, gradually increases from top to bottom. 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 moves the pin closer to the locking groove via the locking plate. The upper part of the locking pin is inserted between the two pin sections, so that when the two pin sections sink, they separate and move apart, thereby causing each pin section to insert into the corresponding insertion hole and aligning each annular groove with the corresponding shaft hole. 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, so as to restrict the two pin segments from moving closer to each other. 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.
