Description

Technical Field

[0001] This invention relates to the field of shoe washing equipment technology, and specifically provides a washing tub assembly for a shoe washing equipment. 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 first cover plate, a second cover plate, a mounting shaft, an elastic torsion member, and a locking member. The mounting shaft is laterally fixed to the opening of the washing tub. The first cover plate and the second cover plate are pivotally connected to the mounting shaft in a back-to-back manner. The elastic torsion member is sleeved on the mounting shaft, and its two torsion ends abut against the bottoms of the first cover plate and the second cover plate, respectively. The elastic torsion member is configured to cause the first cover plate and the second cover plate to flip upwards and open through a rebound action. The locking member is connected to the washing tub... The bucket is connected to / or the mounting shaft. The first cover plate and the second cover plate are respectively provided with a first snap-fit ​​structure. The locking member is provided with two second snap-fit ​​structures that correspond to and match the first snap-fit ​​structures respectively. Each first snap-fit ​​structure can move and snap into the corresponding second snap-fit ​​structure when the first cover plate and the second cover plate are closed into a whole plate surface, so as to enable the first cover plate and the second cover plate to overcome the elastic force of the elastic torsion member and remain in a closed state. It can also disengage from the second snap-fit ​​structure under force so as to allow the elastic torsion member to drive the first cover plate and the second cover plate to spring back and open.

[0007] In the preferred embodiment of the above-mentioned washing tub assembly, the locking component includes a base, an elastic member, a main body, and an unlocking structure disposed on the main body. The base is connected to the opening of the washing tub and / or the mounting shaft. The main body is disposed on the base, the second locking structure is disposed on the main body, and the elastic member is disposed between the main body and the base. When the first locking structure and the second locking structure are engaged, the elastic member can cause the main body to push the second locking structure toward the engaging direction through elastic deformation. When the first cover and the second cover are unlocked, the unlocking structure is subjected to force and, through the main body, drives the second locking structure to move away from the first locking structure. The first locking structure and the second locking structure disengage, thus allowing the first cover and the second cover to flip. When the force on the unlocking structure disappears, the elastic member rebounds to cause the main body to return to the position to be engaged.

[0008] In the preferred embodiment of the above-mentioned washing tub assembly, the first snap-fit ​​structure is a snap-fit ​​hole with the opening facing downwards, the second snap-fit ​​structure is a snap-fit ​​post extending from the main body toward the first cover plate and the second cover plate, the unlocking structure is disposed at the top of the main body, and the elastic member is disposed vertically between the main body and the base. When the first cover plate and the second cover plate are flipped to the closed state, each snap-fit ​​hole is snapped onto the corresponding snap-fit ​​post, the elastic member is pressed and causes the main body to push the snap-fit ​​post upwards, and when the first cover plate and the second cover plate are unlocked, the unlocking structure is pressed and drives the snap-fit ​​post downwards out of the snap-fit ​​hole through the main body.

[0009] In the preferred embodiment of the aforementioned washing tub assembly, the first locking structure is an upward-facing locking hole, and the second locking structure is a locking post extending from the main body toward the first and second cover plates. The unlocking structure is located at the top of the main body, and the elastic member is vertically positioned between the main body and the base. When the first and second cover plates are closed and locked, the unlocking structure is pressed down and, through the main body, moves the locking post downwards. The first and second cover plates are pressed down and closed by the corresponding locking posts, so that the locking post can engage with the corresponding locking hole when the first and second cover plates are closed. The elastic member stretches and deforms, thereby pulling down the main body and pushing the locking post. When the first and second cover plates are unlocked, the unlocking structure is pulled up and, through the main body, moves the locking post upwards out of the locking hole.

[0010] In the preferred embodiment of the washing tub assembly described above, a guide hole is provided on the first cover plate and the second cover plate respectively. The locking hole communicates with the outside through the guide hole, and the diameter of the guide hole gradually increases from the inside to the outside.

[0011] In the preferred embodiment of the above-mentioned washing tub assembly, the base includes a limiting seat and a cover plate. The limiting seat is connected to the opening of the washing tub and / or the mounting shaft. The limiting seat is vertically provided with a receiving groove and a sliding groove. The receiving groove is connected to the outside through the sliding groove. The main body is received in the receiving groove. The locking post extends to the outside through the sliding groove. The cover plate is provided with an installation port. The cover plate is closed in the opening of the receiving groove. The unlocking structure extends to the outside through the installation port. The elastic member is disposed between the main body and the bottom of the receiving groove.

[0012] In the preferred embodiment of the above-mentioned washing tub assembly, the first snap-fit ​​structure is a snap-fit ​​hole arranged laterally, the second snap-fit ​​structure is a snap-fit ​​post extending from the main body toward the first cover plate and the second cover plate, the unlocking structure is disposed at the top of the main body, the elastic member is arranged laterally between the side of the main body away from the snap-fit ​​post and the base, and the base is provided with two blocking structures. When the first cover plate and the second cover plate are unlocked, each snap-fit ​​post abuts against the side of the blocking structure away from the snap-fit ​​hole, and the elastic member is deformed under pressure. When the first cover plate and the second cover plate are locked, the unlocking structure is moved and thus allows the snap-fit ​​post to pop outward away from the blocking structure, so that the two snap-fit ​​posts can be inserted into the corresponding snap-fit ​​holes when the first cover plate and the second cover plate are locked.

[0013] In the preferred embodiment of the above-mentioned washing tub assembly, the elastic torsion structure includes a plurality of torsion spring segments connected end to end. The connection point of each pair of adjacent torsion spring segments extends outward. The two torsion ends are the extension end and the side end after the plurality of torsion spring segments are connected, respectively. The angle between the extension end and the side end in the natural state is set to support the first cover plate and the second cover plate to flip up and open.

[0014] In the preferred embodiment of the above-mentioned washing tub assembly, at least one of the first cover plate and the second cover plate is provided with a shoe washing structure at its bottom.

[0015] In the preferred embodiment of the above-mentioned washing tub assembly, the shoe washing structure includes a first half-brush disposed at the bottom of the first cover plate and a second half-brush disposed at the bottom of the second cover plate.

[0016] When the first cover plate and the second cover plate are flipped and closed, the first half brush and the second half brush can be combined into a whole brush body.

[0017] With the above technical solution, the washing tub of the present invention can be covered or opened by both the first and second cover plates. When the first and second cover plates are unlocked, they can be simultaneously flipped upwards by the elastic torsion member. This design allows the tub lid to automatically flip open after unlocking, without requiring user force. It can be opened smoothly regardless of the orientation of the first and second cover plates after the tub stops rotating. Furthermore, the first and second cover plates stand upright back-to-back at or near the center of the tub opening, giving the tub opening two opening orientations. Even if one of the first and second cover plates is not facing the user, the user can still remove shoes through the exposed portion of the tub opening from either cover, preventing the cover from completely blocking the user's path and improving the convenience of operation after washing shoes.

[0018] Preferably, at least one of the first and second cover plates has a shoe-washing structure at its bottom. This arrangement allows the shoe-washing structure to enter the washing tub after the first and second cover plates are 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 structure and the first and / or second cover plates allows it to be moved to the top of the washing tub each time the first and / or second cover plates are opened, greatly enhancing the convenience for users to clean dirt and lint adhering to the shoe-washing structure.

[0029] 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.

[0030] 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.

[0031] like Figure 1-3As shown, the washing tub assembly of the shoe washing device of the present invention is disposed within the outer casing of the shoe washing device. The washing tub assembly specifically includes a washing tub 1 (shown as the opening portion), a first cover plate 2, a second cover plate 3, a mounting shaft 4, an elastic torsion member 5, and a locking member 6. The washing tub 1 is vertically disposed within the outer casing, with its opening facing upwards. The top of the outer casing, corresponding to the opening of the washing tub 1, has a loading port and an outer cover for opening / closing the loading port. The mounting shaft 4 is horizontally fixed to the opening of the washing tub 1, dividing the opening of the washing tub 1 into two opening portions. The two opening portions can be the same or different in size, as long as either opening portion allows shoes to pass through. The shapes of the first cover plate 2 and the second cover plate 3 respectively match the shapes of the opening portions divided on both sides of the mounting shaft 4, and the adjacent sides of the first cover plate 2 and the second cover plate 3 are pivotally connected to the mounting shaft 4, so that the first cover plate 2 and the second cover plate 3 can be installed at the opening of the washing tub 1 in a back-to-back manner. With both the first cover plate 2 and the second cover plate 3 closed, the first cover plate 2 and the second cover plate 3 flip downwards towards the bucket opening in a nearly horizontal position, away from each other, thus sealing and blocking the bucket opening portions on both sides of the mounting shaft 4. With both the first cover plate 2 and the second cover plate 3 open, the first cover plate 2 and the second cover plate 3 flip upwards away from the bucket opening until they reach their limit positions, where the first cover plate 2 and the second cover plate 3 stand approximately vertically near the mounting shaft 4, exposing the bucket opening portions sealed by the two cover plates to the external environment. The torsion structure of the elastic torsion member 5 is sleeved on the mounting shaft 4, with two torsion ends extending outwards from the torsion structure and abutting against the bottoms of the first cover plate 2 and the second cover plate 3. In their natural state, the two torsion ends extend upwards towards the bucket opening, so that after the first cover plate 2 and the second cover plate 3 flip downwards, the two torsion ends can be pried outwards, thereby allowing the elastic torsion member 5 to cause the first cover plate 2 and the second cover plate 3 to flip upwards and open through the rebound action of the two torsion ends.The locking component 6 is connected to the washing tub 1 and / or the mounting shaft 4. A first snap-fit ​​structure 100 is provided on the first cover plate 2 and the second cover plate 3 respectively. The locking component 6 is provided with two second snap-fit ​​structures 200 that correspond to and match the first snap-fit ​​structures 100 on the first cover plate 2 and the second cover plate 3 respectively. During the process of the first cover plate 2 and the second cover plate 3 flipping down to close, each first snap-fit ​​structure 100 rotates with its respective cover plate. The distance between the first snap-fit ​​structure 100 and its corresponding second snap-fit ​​structure 200 gradually decreases until the first cover plate 2 and the second cover plate 3 are both flipped to the closed position and the two cover plates are closed into a whole plate surface. At this time, the two first snap-fit ​​structures 100 are snapped onto the corresponding second snap-fit ​​structures 200 respectively, so that the snap-fit ​​cooperation of the first snap-fit ​​structure 100 and the second snap-fit ​​structure 200 restricts the first cover plate 2 and the second cover plate 3 from being popped open by the torsion end of the elastic torsion component 5, so that the first cover plate 2 and the second cover plate 3 overcome the rebound force of the elastic torsion component 5 and remain in the closed state. When the first cover plate 2 and the second cover plate 3 are unlocked, the two second locking structures 200 are moved by force to disengage from their respective first locking structures 100. The locking engagement between the first locking structure 100 and the second locking structure 200 disappears, the first cover plate 2 and the second cover plate 3 are no longer subject to flipping limit, the elastic torsion member 5 rebounds and drives the first cover plate 2 and the second cover plate to flip open.

[0032] 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 mounting shaft 4 and the locking member 6 are disposed at the opening of the water-holding tub, and the first cover plate 2 and the second cover plate 3 are used to cover or open the opening of the water-holding tub. When the water-holding tub is rotatable, the first cover plate 2 and the second cover plate 3 rotate synchronously with the water-holding tub. Alternatively, the washing tub 1 may also include an outer tub fixed within the outer shell and an inner tub coaxially disposed within the outer tub. In this case, the mounting shaft 4 and the locking member 6 are disposed at the opening of the inner tub, and the first cover plate 2 and the second cover plate 3 are used to cover or open the opening of the inner tub. When the inner tub is rotatable, the first cover plate 2 and the second cover plate 3 rotate synchronously with the inner tub.

[0033] In addition, the aforementioned mounting shaft 4, first cover plate 2, second cover plate 3 and locking component 6 being positioned at the opening of the washing tub 1 specifically means that the mounting shaft 4, first cover plate 2, second cover plate 3 and locking component 6 are positioned near the opening of the washing tub 1 in a location 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 opening of the washing tub 1, the upper inside of the opening of the washing tub 1, or on accessories installed at the opening of the washing tub 1 (such as the balance ring installed at the opening of the washing tub 1).

[0034] With the above-described design, the first cover 2 and the second cover 3 can automatically pop open after unlocking, eliminating the need for manual opening by the user. Furthermore, the opening of the first cover 2 and the second cover 3 exposes a bucket opening underneath, ensuring that regardless of the orientation of the first cover 2 and the second cover 3 after the washing tub 1 stops rotating, it will not obstruct the user's opening of the tub or the removal of shoes, thus optimizing the ease of use of the shoe washing equipment. In addition, when the first cover 2 and the second cover 3 are closed, they can be reliably locked by the locking component 6. This not only prevents the first cover 2 and the second cover 3 from popping open but also prevents them from colliding with the bucket opening when the washing tub 1 rotates, preventing internal noise from the shoe washing equipment during washing.

[0035] Furthermore, the aforementioned locking member 6 includes a base 61, an elastic member 62, a main body 63, and an unlocking structure 64 disposed on the main body 63. The base 61 is connected to the opening of the washing tub 1 and / or the mounting shaft 4 to securely support it at the opening position of the washing tub 1. The main body 63 is movably disposed on the base 61, and the elastic member 62 is disposed between the main body 63 and the base 61. The aforementioned second locking structure 200 is disposed on the side of the main body 63 near the first locking structure 100 and the second locking structure 200. When the first latching structure 100 on the first cover plate 2 and the second cover plate 3 is latched and locked by its corresponding second latching structure 200, the elastic member 62 can cause the main body 63 to push the second latching structure 200 towards the engaging direction (i.e., the direction in which the second latching structure 200 approaches the first latching structure 100 to achieve latching engagement) through elastic deformation, so that the second latching structure 200 can reliably remain close to and latched with the first latching structure 100, thereby ensuring that the first cover plate 2 and the second cover plate 3 can reliably maintain a closed state. When the first cover plate 2 and the second cover plate 3 are unlocked, the unlocking structure 64 is subjected to force and drives the main body 63 to move, causing the main body 63 to drive the second latching structure 200 away from the first latching structure 100, so that the latching engagement between the first latching structure 100 and the second latching structure 200 is disengaged, so that the first cover plate 2 and the second cover plate 3 are not restricted from flipping, and the elastic torsion member 5 causes the first cover plate 2 and the second cover plate 3 to spring open. When the force on the unlocking structure 64 disappears, the elastic member 62 rebounds to cause the main body 63 to drive the second locking structure 200 back to the locking position. The locking position is the position where the first locking structure 100 can contact and lock with the first locking structure 100 on the first cover plate 2 and the second cover plate 3 after the first cover plate 2 and the second cover plate 3 are flipped down to the closed state.

[0036] In the above embodiments, the base 61 can be assembled together with the mounting shaft 4 and / or the opening of the washing tub 1 by means of connection, or it can be integrally set with the mounting shaft 4 and / or the washing tub 1.

[0037] Furthermore, although the locking member 6 described above is a preferred embodiment combining the base 61, the main body 63, the elastic member 62, and the unlocking structure 64, this does not limit the scope of protection of the present invention. Those skilled in the art can add or reduce the structure included in the locking member 6 according to the locking and unlocking requirements. For example, the locking member 6 may also omit the base 61 and directly provide the main body 63 and the elastic member 62 at the opening of the mounting shaft 4 and / or the washing tub 1.

[0038] Furthermore, the specific structures of the first latching structure 100 and the second latching structure 200 are not limited. As long as the selected latching structure combination can achieve latching and locking of the first cover plate 2 and the second cover plate 3, and disengaging and unlocking of the first cover plate 2 and the second cover plate 3, it is acceptable. Those skilled in the art can set the specific structures of the first latching structure 100 and the second latching structure 200 according to the locking and unlocking requirements. For example, one of the first latching structure 100 and the second latching structure 200 can be set as a latching hole, a latching groove, or a latch, or one of the first latching structure 100 and the second latching structure 200 can be set as a latching post, a latching block, or a latching tongue.

[0039] Furthermore, the aforementioned unlocking structure 64 is subjected to force in two scenarios: manual unlocking when the user applies force to operate the unlocking structure 64, and automatic unlocking when the drive structure applies force to drive the unlocking structure 64 to move. When set to automatic unlocking, the unlocking structure 64 can be driven by a power device such as a drive motor or hydraulic drive device, or a combined power device and a transmission structure such as a gear assembly / linkage assembly, to move the main body 63 in the unlocking direction (i.e., the direction that causes the second locking structure 200 to move away from the first locking structure 100).

[0040] like Figure 1-5As shown, in the first embodiment of the present invention, the base 61 is disposed on the side of the first cover plate 2 and the second cover plate 3, and is located near the mounting shaft 4. As an example, one side of the first cover plate 2 and the second cover plate 3 in the same direction is not close to the washing tub 1, and a certain installation space is left between this side of the two cover plates and the edge of the tub opening of the washing tub 1, and the base 61 is fixed in this installation space. The base 61 specifically includes a limiting seat 611 and a cover plate 612. The limiting seat 611 has a receiving groove 6111 arranged vertically inside, and a sliding groove 6112 and a shaft hole 6113 are provided on the side of the limiting seat 611 near the first cover plate 2 and the second cover plate 3. There are two sliding grooves 6112, and the two sliding grooves 6112 are respectively arranged through the side of the limiting seat 611, so as to open two passages between the receiving groove 6111 and the outside. The shaft hole 6113 is located below the slide groove 6112. One end of the mounting shaft 4 is fixed to the opening of the washing tub 1, and the other end of the mounting shaft 4 is fixed inside the shaft hole 6113. The end of the limiting seat 611 away from the first cover plate 2 and the second cover plate 3 is connected to the opening of the washing tub 1, so that the mounting shaft 4 and the limiting seat 611 are fixed together to the opening of the washing tub 1. Preferably, the mounting shaft 4 and the limiting seat 611 are arranged radially along the washing tub 1. The first cover plate 2 and the second cover plate 3 are two semi-circular cover plates with a notch on one side, so as to evenly divide the opening of the washing tub 1 into two opening portions. The main body 63 is disposed in the receiving groove 6111. One end of the elastic member 62 abuts / connects to the top of the main body 63, and the other end of the elastic member 62 abuts / connects to the bottom of the receiving groove 6111. The receiving groove 6111 is configured to allow the main body 63 to move vertically up and down within it. A cover plate 612 is disposed on top of the limiting seat 611, closing the opening of the receiving groove 6111 to restrict the main body 63 from moving out of the receiving groove 6111. An unlocking structure 64 is disposed on top of the main body 63, and a mounting opening 6121 is provided on the cover plate 612 corresponding to the unlocking structure 64, through which the unlocking structure 64 extends to the outside of the cover plate 612. Two second snap-fit ​​structures 200 are snap-fit ​​posts disposed on the sides of the main body 63 near the first cover plate 2 and the second cover plate 3, and each snap-fit ​​post extends outward along the direction near the first cover plate 2 and the second cover plate 3 through a sliding groove 6112. The two first snap-fit ​​structures 100 are snap-fit ​​holes that match the snap-fit ​​posts. The two snap-fit ​​holes are respectively set on the side of the first cover plate 2 and the second cover plate 3 near the limiting seat 611. The opening of the snap-fit ​​hole is set downward and passes through the bottom of the first cover plate 2 and the second cover plate 3. The shape of the inner end of the snap-fit ​​hole away from its opening matches the snap-fit ​​post, so that after the snap-fit ​​post is snapped into the inner end of the snap-fit ​​hole, the snap-fit ​​post will not come out of the snap-fit ​​hole under non-external force.

[0041] Based on the above structural configuration, during the downward flipping of the first cover plate 2 and the second cover plate 3, the first cover plate 2 and the second cover plate 3 rotate downwards and approach the opening of the washing tub 1, and the locking holes on the first cover plate 2 and the second cover plate 3 continuously approach the locking post.

[0042] When the first cover plate 2 and the second cover plate 3 are flipped to the closed state, the opening of each locking hole is aligned and allows the respective locking pin to enter. The locking pin is tightly locked in the locking hole, preventing the locking hole from disengaging from the locking pin. This restricts the first cover plate 2 and the second cover plate 3 from flipping upward. The elastic member 62 is compressed and causes the main body 63 to have an upward tendency, so that the main body 63 pushes the locking pin upward and causes the locking pin to maintain the state of being locked against the inner end of the locking hole away from the opening.

[0043] When the first cover plate 2 and the second cover plate 3 need to be unlocked and opened, the user or the driving device presses the unlocking structure 64 downward. The unlocking structure 64 is pressed and drives the main body 63 to move downward, so that the two locking pins connected to the main body 63 move toward their respective locking hole openings and disengage from the locking holes. The locking engagement between the locking holes and the locking pins is eliminated, and the first cover plate 2 and the second cover plate 3 are flipped upward and opened to the open state.

[0044] After the cover is opened, the user or the driving device releases the unlocking structure 64. The pressure on the unlocking structure 64 disappears, the elastic member 62 stretches and rebounds, causing the main body 63 to drive the locking post to reset to a position where it can engage with the locking holes in the closed positions of the two cover plates.

[0045] Furthermore, a guide hole 300 is provided on the first cover plate 2 and the second cover plate 3 respectively. The guide hole 300 is located at the open end of the locking hole. Each locking hole is connected to the outside through a guide hole 300. The diameter of the guide hole 300 gradually increases from the inside (the side where the guide hole 300 is connected to the opening of the locking hole) to the outside (the opening side of the guide hole 300), so that the guide hole 300 has an expanded shape, which facilitates the smooth entry of the locking pin into the guide hole 300 during the movement of the locking hole, thereby guiding the locking pin into the locking hole and improving the locking smoothness when the first cover plate 2 and the second cover plate 3 are closed.

[0046] In the first embodiment described above, the elastic member 62 can be any type of elastic member capable of being compressed vertically and then stretching back, such as a spring or a sheet. The number of elastic members 62 can be one or more.

[0047] Furthermore, the structure of the base 61 is not limited to the combination of the limiting seat 611 and the cover plate 612. In the case where the main body 63 is connected to the receiving groove 6111 through the elastic member 62 and aesthetic factors are not considered, the cover plate 612 may not be provided, and the main body 63 and the elastic member 62 may be installed only through the limiting seat 611.

[0048] Furthermore, without affecting the flipping of the first cover plate 2 and the second cover plate 3, the positions of the locking pin and the locking hole can be interchanged. That is, the first locking structure 100 can be set as a locking pin, and the second locking structure 200 can be set as a locking hole. In this case, the locking pin that is adapted to move downward in the closed state can have the locking hole set on the main body 63 with the opening facing upward, so that the locking pin can be tightly locked into the locking hole through the sliding groove 6112 after the two cover plates are closed.

[0049] With the above settings, the first cover plate 2 and the second cover plate 3 can automatically align the locking hole and the locking pin with the lock during the flip-closing process. The closing and locking actions can be completed synchronously. Moreover, when unlocking, only the unlocking structure 64 needs to be pressed once to open the first cover plate 2 and the second cover plate 3, which is very convenient to operate.

[0050] In the second embodiment of the present invention, unlike the first embodiment described above, the opening of the card hole is arranged facing upward, the carding post is arranged above the first cover plate 2 and the second cover plate 3 near the mounting shaft 4, and the elastic member 62 is arranged between the main body 63 and the receiving groove 6111 in a stretched manner.

[0051] With the above configuration, when the first cover plate 2 and the second cover plate 3 are open, the snap-fit ​​post abuts against the top of the first cover plate 2 and the second cover plate 3 in the open state, and the elastic torsion member 5 prevents the elastic member 62 from driving the main body 63 to retract downward.

[0052] When the first cover plate 2 and the second cover plate 3 are closed and locked, the unlocking structure 64 is pressed and moves the locking pin downward through the main body 63. The two locking pins abut against the top of the first cover plate 2 and the second cover plate 3 respectively, pressing the first cover plate 2 and the second cover plate 3 to flip downward until the unlocking structure 64 is pressed down to the limit position. The locking pin moves down to the lowest position, enters and tightly locks into the inner end of the locking hole. At this time, the first cover plate 2 and the second cover plate 3 are both in the closed state. The locking engagement of the locking pin and the locking hole restricts the first cover plate 2 and the second cover plate 3 from flipping upward. The elastic member 62 is stretched and deformed, thus pulling down the main body 63 and pushing the locking pin downward, helping the locking pin to stay in the state of staying in the inner end of the locking hole.

[0053] When the first cover plate 2 and the second cover plate 3 are unlocked and opened, the unlocking structure 64 is pulled upward and the main body 63 drives the locking pin to move upward and disengage from the locking hole. The first cover plate 2 and the second cover plate 3 are driven upward and flipped open by the elastic torsion member 5. The popped-open first cover plate 2 and the second cover plate 3 cause the locking pin to reset, so that the unlocking structure 64 returns to the position where it can lock the two cover plates after being pressed.

[0054] like Figure 7As shown, in the third embodiment of the present invention, unlike the first and second embodiments described above, the card hole is arranged laterally, and the opening of the card hole is formed on the side of the first cover plate 2 and the second cover plate 3 near the limiting seat 611. The elastic member 62 is arranged in a compressed manner between the side of the main body 63 away from the card hole and the receiving groove 6111. A blocking structure 400 is respectively provided in the receiving groove 6111 for each of the two carding posts. The mounting port 6121 at the top of the cover plate 612 allows the unlocking structure 64 to drive the two carding posts to retract into the receiving groove 6111 and abut against their respective blocking structures 400.

[0055] With the above settings, when the first cover plate 2 and the second cover plate 3 are not locked, the snap-fit ​​post retracts into the receiving groove 6111 and the snap-fit ​​end abuts against the blocking structure 400, the elastic member 62 is compressed, and the first cover plate 2 and the second cover plate 3 can be freely flipped open and closed.

[0056] When the first cover plate 2 and the second cover plate 3 need to be closed and locked, the first cover plate 2 and the second cover plate 3 are rotated to the closed position, and the unlocking structure 64 is activated, causing the unlocking structure 64 to move through the main body 63, causing the locking pin to be offset from the blocking structure 400, so that the locking pin can be ejected outward by the elastic member 62 through the slide groove 6112, the locking pin is inserted and locked into the locking hole, and the first cover plate 2 and the second cover plate 3 are restricted from rotating and kept in the closed state.

[0057] When the first cover plate 2 and the second cover plate 3 need to be unlocked, simply move the unlocking mechanism 64 away from the first cover plate 2 and the second cover plate 3 (i.e., Figure 7 (As shown by the right arrow), causing the locking pin to retract from the locking hole, the first cover 2 and the second cover 3 can be automatically popped open. Then, the unlocking structure 64 is moved towards the position of the blocking structure 400 (i.e., Figure 7 (As shown by the upward arrow), this causes the locking pin to return to the position abutting against the blocking structure 400, so that it can move out to lock the two covers after the first cover 2 and the second cover 3 are closed next time.

[0058] Of course, the blocking structure 400 can be omitted, and the snapping ends of the two snapping pins can be replaced with end faces that gradually slope downwards along the direction close to the first cover plate 2 and the second cover plate 3. In this case, the two snapping pins do not need to retract into the receiving cavity. When the first cover plate 2 and the second cover plate 3 are flipped downwards, they will contact each other and slide along the end faces of the snapping pins, causing the snapping pins to retract into the receiving groove 6111 until the first cover plate 2 and the second cover plate 3 are closed in place, the snapping hole and the snapping pin are aligned, so that the snapping pin can pop out and snap into the snapping hole to lock the two cover plates.

[0059] like Figure 6As shown, for any of the above embodiments, preferably, the elastic torsion structure includes a plurality of torsion spring segments 51 connected end to end in sequence. The position where each pair of adjacent torsion spring segments 51 are connected extends outward. One of the two torsion ends of the elastic torsion structure is the outward end 52 after the plurality of torsion spring segments 51 are connected, and the other is the side end 53 of the torsion spring ends on both ends that are not connected to other torsion spring segments 51. Figure 6 The elastic torsion member 5 shown includes two torsion spring segments 51, with two side ends 53 on the left and right sides and a branch end 52 between the two torsion spring segments 51. When installed, the two torsion spring segments 51 are sleeved on the mounting shaft 4, the two side ends 53 abut against the bottom of the first cover plate 2 / second cover plate 3, and the branch end 52 abuts against the bottom of the second cover plate 3 / first cover plate 2. The angle between the branch end 52 and the side ends 53 in their natural state is set to support the first cover plate 2 and the second cover plate 3 to flip upwards and open, so that after the elastic torsion member 5 rebounds, it can cause the first cover plate 2 and the second cover plate 3 to rotate to their maximum opening angle.

[0060] Preferably, at least one of the first cover plate 2 and the second cover plate 3 is provided with a shoe washing structure 7 at its bottom. When a portion of the shoe washing structure 7 is provided at the bottom of both the first cover plate 2 and the second cover plate 3, the shoe washing structure 7 specifically includes a first half-brush provided at the bottom of the first cover plate 2 and a second half-brush provided at the bottom of the second cover plate 3. The first half-brush and the second half-brush are arranged opposite to each other so that when the first cover plate 2 and the second cover plate 3 are flipped and closed, the first half-brush and the second half-brush can be combined into a whole brush body.

[0061] With the above settings, when the first cover plate 2 and the second cover plate 3 are opened, the first half brush and the second half brush will be ejected respectively, so that the first half brush and the second half brush can be in a position that is easily accessible to the outside after the two covers are opened, thus improving the convenience for users to clean the first half brush and the second half brush.

[0062] Furthermore, the aforementioned washing tub 1 is rotatably configured, such as by rotating the water tank or inner tub. A pulsator is positioned at the bottom of the water tank or inner tub, and a shoe-washing brush is positioned 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 first and second half-brushes at the bottom of the first and second covers to rotate with the inner tub. The shoe-washing brush at the top of the pulsator is 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 pulsator to rotate separately; therefore, the specific structure of the drive device will not be described in detail here). When washing shoes, the shoes can be washed by the combined brush body, consisting of the rotating shoe-washing brush at the bottom and the rotating first and second half-brushes at the top, moving up and down respectively, allowing for comprehensive 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 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.

[0063] Furthermore, the radial dimension of the brush body formed by the first and second half-brushes is set to gradually increase from the top to the bottom (see...). Figure 2 (Example) This allows the composite brush body to have an expanded brushing surface. For example, both the first and second half-brushes are configured as quarter-spherical brushes so that they can form a hemispherical brush body when brought close together. When the hemispherical brush body rotates, the vortex of washing water near the brush body can cause lighter shoes floating above the washing water to rotate around the hemispherical brush body, so that the bristles expanded by the hemispherical brush body can reliably rub and clean the shoes for a long time. Furthermore, the expanded brush body can reliably receive shoes floating from the bottom and can rub against the shoes from any position in its circumference, increasing the brushing angle and greatly optimizing the overall shoe washing effect of the shoe washing equipment.

[0064] Preferably, a plug-in structure can be provided on the side of the first half-brush and the second half-brush that are close to each other. The two plug-in structures can be plugged in after the first half-brush and the second half-brush are combined, so as to limit the first half-brush and the second brush from twisting due to the collision of the shoes when washing shoes, thereby enhancing the durability of the first half-brush and the second half-brush.

[0065] 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 first cover plate, a second cover plate, a mounting shaft, an elastic torsion member, and a locking member. The mounting shaft is laterally fixed to the opening of the washing tub. The first cover plate and the second cover plate are pivotally connected to the mounting shaft in a manner that separates them from each other. The elastic torsion member is sleeved on the mounting shaft, and its two torsion ends abut against the bottoms of the first cover plate and the second cover plate, respectively. The elastic torsion member is configured to cause the first cover plate and the second cover plate to flip upwards and open through a springback action. The locking component is connected to the washing tub and / or the mounting shaft. The first cover plate and the second cover plate are each provided with a first snap-fit ​​structure, and the locking component is provided with two second snap-fit ​​structures that correspond to and match the first snap-fit ​​structures respectively. Each of the first snap-fit ​​structures is capable of moving and snapping into the corresponding second snap-fit ​​structure when the first cover plate and the second cover plate are closed into a single plate surface, so as to cause the first cover plate and the second cover plate to overcome the elastic force of the elastic torsion member and remain in a closed state. It can also disengage from the second snap-fit ​​structure under stress, so that the elastic torsion member can cause the first cover and the second cover to spring back open.

2. The washing tub assembly according to claim 1, characterized in that, The locking component includes a base, an elastic component, a main body, and an unlocking structure disposed on the main body. The base is connected to the opening of the washing tub and / or the mounting shaft; the main body is disposed on the base; the second snap-fit ​​structure is disposed on the main body; and the elastic member is disposed between the main body and the base. When the first and second locking structures are engaged, the elastic member can cause the main body to push the second locking structure toward the engagement direction through elastic deformation. When the first cover plate and the second cover plate are unlocked, the unlocking structure is subjected to force and, through the main body, drives the second locking structure to move away from the first locking structure. The first locking structure disengages from the second locking structure, thus allowing the first cover plate and the second cover plate to flip over. When the force applied to the unlocking structure disappears, the elastic member rebounds to cause the main body to return to the position to be engaged.

3. The washing tub assembly according to claim 2, characterized in that, The first snap-fit ​​structure is a downward-facing snap-fit ​​hole; the second snap-fit ​​structure is a snap-fit ​​post extending from the main body toward the first cover plate and the second cover plate; the unlocking structure is located at the top of the main body; and the elastic member is vertically positioned between the main body and the base. When the first cover plate and the second cover plate are flipped to the closed state, each of the locking holes engages with the corresponding locking post, and the elastic member is compressed, causing the main body to push the locking post upward. When the first cover plate and the second cover plate are unlocked, the unlocking structure is pressed and drives the locking pin downward to disengage from the locking hole through the main body.

4. The washing tub assembly according to claim 2, characterized in that, The first snap-fit ​​structure is an upward-facing snap-fit ​​hole; the second snap-fit ​​structure is a snap-fit ​​post extending from the main body toward the first cover plate and the second cover plate; the unlocking structure is located at the top of the main body; and the elastic member is vertically positioned between the main body and the base. When the first and second cover plates are closed and locked, the unlocking structure is pressed and moves the locking pin downwards via the main body. The first and second cover plates are pressed down and closed by the corresponding locking pins, so that the locking pins can engage with the corresponding locking holes when the first and second cover plates are closed. The elastic member stretches and deforms, thereby pulling down the main body and pushing the locking pins. When the first cover plate and the second cover plate are unlocked, the unlocking structure is pulled upward and the main body drives the locking pin upward to disengage from the locking hole.

5. The washing tub assembly according to claim 3 or 4, characterized in that, The first cover plate and the second cover plate are each provided with a guide hole. The card hole communicates with the outside through the guide hole, and the diameter of the guide hole gradually increases from the inside to the outside.

6. The washing tub assembly according to claim 3 or 4, characterized in that, The base includes a limiting seat and a cover plate. The limiting seat is connected to the opening of the washing tub and / or the mounting shaft. The limiting seat has a receiving groove and a sliding groove vertically arranged on its upper edge. The receiving groove is connected to the outside through the sliding groove. The main body is housed within the receiving groove, and the snap-fit ​​post extends to the outside through the sliding groove. The cover plate is provided with an installation port, and the cover plate is closed within the opening of the receiving groove. The unlocking structure extends to the outside through the installation port. The elastic member is disposed between the main body and the bottom of the receiving groove.

The base is provided with two blocking structures. When the first cover plate and the second cover plate are unlocked, each locking post abuts against the blocking structure on the side away from the locking hole, and the elastic member deforms under pressure. When the first cover plate and the second cover plate are locked, the unlocking structure is toggled and thus allows the locking pins to pop outward, offset from the blocking structure, so that the two locking pins can be inserted into the corresponding locking holes when the first cover plate and the second cover plate are locked.

8. The washing tub assembly according to claim 1, characterized in that, The elastic torsion member comprises multiple torsion spring segments connected end to end. The connection point between any two adjacent torsion spring segments extends outwards. The two torsion ends are the outward end and the side end of the connection of the multiple torsion spring segments, respectively.
