Description

Technical Field

[0001] This utility model relates to the field of shoe tree technology, specifically to an adjustable shoe tree, a shoe cleaning device, and a cleaning equipment. Background Technology

[0002] During shoe washing, shoe trees support and stabilize the shoes, ensuring they maintain a relatively stable shape. However, most shoe trees on current shoe washing equipment are difficult to adjust flexibly to fit the shoe shape, thus failing to effectively conform to the inside of the shoe. This makes the shoes prone to becoming soft and deformed during washing, which not only changes the original appearance and wearing comfort of the shoes but also prevents some details inside the shoe from being thoroughly cleaned, creating cleaning dead spots and seriously affecting the cleaning quality. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In shoe washing equipment technology, shoe trees mostly use a fixed size and shape design, making it difficult to adapt to diverse shoe shapes. In particular, once inserted into the shoe, the shoe tree cannot achieve an effective fit. This lack of fit can cause a series of problems during the actual shoe washing process.

[0005] On the one hand, shoes are prone to becoming soft and deformed during the washing process. When shoe trees cannot provide sufficient support, the original shape and structure of the shoes are easily damaged under the friction of water flow and washing equipment, thus changing the original appearance of the shoes and affecting their aesthetics. At the same time, the deformation of the shoes will also lead to a significant reduction in wearing comfort, because the change in the shape of the shoes may prevent the feet from receiving proper support and wrapping when wearing them, increasing foot fatigue.

[0006] On the other hand, a mismatch between the shoe tree and the inside of the shoe can severely affect the cleaning quality. Because the shoe tree cannot effectively fill the internal space of the shoe, some detailed areas inside, such as the inside of the toe, the heel recess, and around the shoelace eyelets, will not be able to fully contact the cleaning water and cleaning tools due to insufficient coverage by the shoe tree, thus creating cleaning dead zones. Dirt and stains in these cleaning dead zones are difficult to remove thoroughly, resulting in unclean shoes, affecting not only the hygiene of the shoes but also potentially shortening their lifespan.

[0007] Therefore, this utility model provides an adjustable shoe tree, a shoe cleaning device, and a cleaning equipment, which can effectively fit the inside of the shoe and help improve the shoe's support effect.

[0008] The adjustable shoe support provided by this utility model includes:

[0009] A support body includes a heel portion, a middle portion, and a toe portion connected together. The heel portion and the toe portion are respectively located on opposite sides of the middle portion, and at least one of the heel portion and the toe portion is movable relative to the middle portion.

[0010] A side support assembly includes a support rod, a first side support, and a second side support. The support rod extends along the height direction of the support body and is connected to the support body. The first side support and the second side support are respectively located on opposite sides of the support body in the width direction. Both the first side support and the second side support include a swing rod and a support plate. The two ends of the swing rod are correspondingly connected to the support rod and the support plate. The support plate is used to support the side of the shoe. When one of the first side support and the second side support is subjected to force, the two support plates can swing towards or away from each other to adjust the opening width of the side support assembly.

[0011] In summary, the adjustable shoe tree provided by this utility model, through its adjustable support body and adjustable side support components, can achieve dual adjustment in both length and width. This not only improves the versatility of the shoe tree, making it adaptable to shoes of different sizes and shapes, but also enhances its flexibility and practicality. Users can easily adjust the length and width of the shoe tree according to the actual needs of the shoes, thereby providing the best support effect.

[0012] In some embodiments, the swing rod is rotatably connected to the support rod, and the swing rod is provided with synchronous meshing teeth. The synchronous meshing teeth of the first side support and the synchronous meshing teeth of the second side support are correspondingly meshed, so that the first side support and the second side support swing synchronously.

[0013] In some embodiments, the side support assembly further includes an adjusting sleeve, which is slidably fitted onto the support rod. The adjusting sleeve has a first position and a second position relative to the support rod. When the adjusting sleeve is in the first position, at least a portion of the swing rod is inserted into the adjusting sleeve. The opening width between the first side support and the second side support is A. When the adjusting sleeve is in the second position, the opening width between the first side support and the second side support is B, and A is less than B.

[0014] In some embodiments, the side support assembly further includes a snap fastener and a first elastic member. The snap fastener is rotatably connected to the adjusting sleeve. The snap fastener has a snap head. The support rod is provided with a slot that mates with the snap head. The two ends of the first elastic member are correspondingly connected to the snap fastener and the adjusting sleeve. When the adjusting sleeve is in the first position, the snap head snaps into the slot.

[0015] In some embodiments, at least one of the heel portion and the toe portion is provided with a guide block, the guide block having a first guide slope, and the adjusting sleeve having a second guide slope that cooperates with the first guide slope. When the adjusting sleeve moves from a second position to a first position, the adjusting sleeve moves toward the support body, and the second guide slope pushes against the first guide slope, causing the toe portion and the heel portion to move toward each other.

[0016] In some embodiments, the middle portion is provided with a synchronizing gear, the heel portion is provided with a first rack, and the toe portion is provided with a second rack. The first rack and the second rack are located on opposite sides of the synchronizing gear, and both the first rack and the second rack mesh with the synchronizing gear.

[0017] In some embodiments, the support body further includes a second elastic member, one end of which is connected to the middle portion, and the other end of which is connected to the heel portion and / or the toe portion.

[0018] In some embodiments, the support body further includes an upper support and a third elastic member, the upper support being rotatably connected to the toe of the shoe, one end of the third elastic member abutting against the upper support, and the other end of the third elastic member abutting against the toe of the shoe;

[0019] And / or, the heel, middle part, and toe of the shoe are each provided with a hollow cavity, the hollow cavity being used to store the cleaning medium, and the surface of the heel, the middle part, and the toe of the shoe are each provided with a spray hole, the spray hole being used to spray the cleaning medium in the hollow cavity into the inner cavity of the shoe.

[0020] In addition, the shoe cleaning device provided by this utility model includes the adjustable shoe support provided in any of the above embodiments.

[0021] The cleaning equipment provided by this utility model includes the shoe cleaning device provided in the above embodiments or the adjustable shoe support provided in any of the above embodiments. Attached Figure Description

[0039] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] refer to Figures 1 to 9 As shown, this utility model embodiment provides an adjustable shoe support, which includes a support body 10 and a side support assembly 20. The support body 10 includes a heel portion 11, a middle portion 12 and a toe portion 13 connected to each other. The heel portion 11 and the toe portion 13 are respectively located on opposite sides of the middle portion 12, and at least one of the heel portion 11 and the toe portion 13 is movable relative to the middle portion 12.

[0041] The side support assembly 20 includes a support rod 21, a first side support 22, and a second side support 23. The support rod 21 extends along the height direction of the support body 10 and is connected to the support body 10. The first side support 22 and the second side support 23 are respectively located on opposite sides of the support body 10 in the width direction. Both the first side support 22 and the second side support 23 include a swing rod 241 and a support plate 242. The two ends of the swing rod 241 are connected to the support rod 21 and the support plate 242 respectively. The support plate 242 is used to support the side of the shoe. When one of the first side support 22 and the second side support 23 is subjected to force, the two support plates 242 can swing towards or away from each other to adjust the opening width of the side support assembly 20.

[0042] Specifically, the support body 10 is the core structure of the adjustable shoe tree provided by this utility model. It can be flexibly adjusted according to the actual length of the shoe by moving at least one of the heel part 11 or the toe part 13 relative to the middle part 12. For example, when supporting a longer shoe, the user can move the heel part 11 or the toe part 13 outwards to increase the overall length of the shoe tree; conversely, when supporting a shorter shoe, the user can move the heel part 11 or the toe part 13 inwards to decrease the length of the shoe tree. Through this simple movement, the shoe tree can adapt to shoes of various sizes and lengths, greatly improving its versatility and practicality.

[0043] The side support assembly 20 serves as an auxiliary component of the shoe support, providing additional support on both sides (sidewalls) of the shoe to prevent deformation during storage, drying, or washing. The first side support frame 22 and the second side support frame 23 are located on opposite sides of the support body 10. The two ends of the swing rod 241 are connected to the support rod 21 and the support plate 242, respectively. The support plate 242 directly abuts against the sidewall of the shoe, giving the side support assembly 20 high flexibility. When the first side support frame 22 or the second side support frame 23 is subjected to external force, the two support plates 242 can swing towards or away from each other, thereby adjusting the opening width of the side support assembly 20. For example, when supporting a wider shoe, external force can be applied to swing the two support plates 242 away from each other, increasing the opening width of the side support assembly 20; conversely, when supporting a narrower shoe, external force can be applied to swing the two support plates 242 towards each other, decreasing the opening width. This adjustable side support component 20 can not only adapt to shoes of different widths, but also ensure that the shoes maintain their shape during washing, storage and other processes, preventing deformation.

[0044] In summary, the adjustable shoe tree provided by this utility model, through its adjustable support body 10 and adjustable side support assembly 20, can achieve dual adjustment in both length and width. This not only improves the versatility of the shoe tree, making it adaptable to shoes of different sizes and shapes, but also enhances its flexibility and practicality. Users can easily adjust the length and width of the shoe tree according to the actual needs of the shoes, thereby providing the best support effect.

[0045] It should be noted that in the adjustable shoe support provided in this application, the outer surfaces of the heel portion 11, the middle portion 12, and the toe portion 13 all have smooth curved surfaces to adapt to the shoe cavity and prevent scratches on the shoe. Optionally, the support rod 21 can be threadedly connected to the middle portion 12.

[0046] Furthermore, in this application Figure 1In the adjustable shoe tree shown, the length direction of the support body is the front-to-back direction indicated by the arrow in the figure, and the width direction of the support body is the left-to-right direction indicated by the arrow in the figure. Of course, in some other embodiments, the length and width directions of the support body may differ from the example in the figure depending on the position or placement angle of the adjustable shoe tree. Please refer to the specific structure for comparison and description, which will not be elaborated here.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the swing rod 241 is rotatably connected to the support rod 21. The swing rod 241 is provided with synchronous meshing teeth 243. The synchronous meshing teeth 243 of the first side support 22 and the synchronous meshing teeth 243 of the second side support 23 are correspondingly meshed, so that the first side support 22 and the second side support 23 swing synchronously.

[0048] Specifically, the swing rod 241 is rotatably connected to the support rod 21, allowing the swing rod 241 to rotate relative to the support rod 21, thereby realizing the swing function of the pallet 242. The swing rod 241 is provided with synchronous meshing teeth 243, that is, the synchronous meshing teeth 243 on the swing rod 241 of the first side support 22 correspond to and mesh with the synchronous meshing teeth 243 on the swing rod 241 of the second side support 23, ensuring that the first side support 22 and the second side support 23 always maintain synchronous movement during the swing.

[0049] That is, when the support plate 242 or the swing rod 241 of the first side support 22 is subjected to an external force and swings, the synchronous meshing teeth 243 on the swing rod 241 will drive the synchronous meshing teeth 243 on the swing rod 241 of the second side support 23 to move together. Due to the meshing action of the synchronous meshing teeth 243, the support plate 242 of the second side support 23 will also swing accordingly. Conversely, when the support plate 242 of the second side support 23 is subjected to an external force, the same principle also applies to the first side support 22, thereby ensuring that the two support plates 242 always maintain the same swing angle and direction.

[0050] Furthermore, the synchronizing teeth 243 are arranged in a fan shape, thus providing a large range of meshing angles. This means that the meshing teeth maintain a good meshing state throughout the entire rotation of the swing rod 241, and there will be no tooth disengagement or slippage even at large swing angles. This design greatly enhances the reliability and stability of the side support assembly 20 when adjusting the opening width. At the same time, compared with the traditional meshing gear design, the fan-shaped synchronizing teeth 243 design occupies less space while achieving the function, making the overall structure more compact and avoiding excessive local structural size of the swing rod 241 at the synchronizing teeth 243, which helps to reduce the size of the structure.

[0051] Furthermore, the support rod 21 is provided with a mounting base 211, the mounting base 211 is provided with a first positioning hole 2111, the rotating end of the swing rod 241 is provided with a second positioning hole 2411, and a first positioning shaft can be inserted into the first positioning hole 2111 and the second positioning hole 2411, thereby realizing the rotational connection between the swing rod 241 and the support rod 21.

[0052] Optionally, the synchronous meshing teeth 243 are provided at the rotating end of the swing rod 241, and the mounting base 211 can be provided in the middle or lower part of the support rod 21. In the length direction of the support rod 21, the end closer to the support body 10 is designated as the lower part, and the end farther away from the support body 10 is designated as the upper part. Correspondingly, the mounting base 211 is located on the side of the support rod 21 closer to the support body 10.

[0053] like Figure 2 and Figure 4 As shown, in this embodiment, the swing rod 241 includes a first connecting rod 2412 and a second connecting rod 2413 connected to each other. The first connecting rod 2412 is rotatably connected to the support rod 21. A second positioning hole 2411 is provided in the first connecting rod 2412. The first connecting rod 2412 and the second connecting rod 2413 are arranged in an L-shape. The second connecting rod 2413 extends along the length direction of the support body 10. The support plate 242 is connected to the second connecting rod 2413. The plane where the support plate 242 is located is at an angle to the extension direction of the second connecting rod 2413 so that the support plate 242 can fit more closely to the side of the shoe.

[0054] Furthermore, both the first side support 22 and the second side support 23 also include guide strips 244 and adjusting members 245. The guide strips 244 are connected to the support plate 242. The middle part 12 of the support body 10 is provided with a guide groove 121, which runs through the middle part 12 in the left-right direction. The guide strips 244 are movably inserted into the guide grooves 121, so that the side supports can move along a preset path when they are opened or closed, avoiding the side supports from deviating or swaying during movement, thereby improving the overall stability and reliability of the shoe support. That is, the guide grooves 121 provide a fixed movement track for the guide strips 244, ensuring that the guide strips 244 always maintain a straight line movement during movement.

[0055] Furthermore, the guide strip 244 is provided with mounting holes 2441. One end of the adjusting member 245 in the first side support 22 passes through the mounting hole 2441 to abut against the guide strip 244 of the second side support 23. This allows for fine-tuning of the misalignment of the first side support 22 and the second side support 23 along the length of the support body 10, resulting in a more precise support effect. In other words, if the second side support 23 needs to be moved forward (i.e., closer to the toe), the guide strip 244 of the second side support 23 can be pushed forward by the adjusting member 245. Similarly, if the second side support 23 needs to be moved backward (i.e., closer to the heel), the guide strip 244 of the second side support 23 can be pulled backward by the adjusting member 245.

[0056] In addition, the adjusting member 245 is fixed to the guide strip 244 of one of the first side support 22 and the second side support 23 through the mounting hole 2441, and uses one end to abut against the guide strip 244 of the other of the first side support 22 and the second side support 23, so that the distance between the two guide strips 244 can be adjusted to fit the inner wall of the guide groove 121, thereby fixing the position of the guide strip 244, and correspondingly fixing the opening width of the side support assembly 20.

[0057] Optionally, the mounting hole 2441 may be a threaded hole, and the adjusting member 245 may have a threaded section that mates with the threaded hole.

[0058] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the side support assembly 20 further includes an adjusting sleeve 25, which is slidably sleeved on the support rod 21. The adjusting sleeve 25 has a first position and a second position relative to the support rod 21. When the adjusting sleeve 25 is in the first position, at least a portion of the swing rod 241 is inserted into the adjusting sleeve 25, and the opening width between the first side support 22 and the second side support 23 is A. When the adjusting sleeve 25 is in the second position, the opening width between the first side support 22 and the second side support 23 is B, and A is less than B.

[0059] Specifically, the support rod 21 extends vertically, and the adjusting sleeve 25 is hollow. The adjusting sleeve 25 is fitted onto the outside of the support rod 21 and is slidable relative to the support rod 21, so that the support rod 21 has a first position and a second position, and the adjusting sleeve 25 at the first position is closer to the support body 10 than the adjusting sleeve 25 at the second position. Figure 5As shown, when the adjusting sleeve 25 is in the first position, at least part of the swing rod 241 is inserted into the interior of the adjusting sleeve 25. At this time, the opening width between the first side support 22 and the second side support 23 is named A. When the adjusting sleeve 25 moves from the first position away from the support body 10 along the support rod 21 until it moves to the second position, the opening width between the first side support 22 and the second side support 23 will increase from A to B. Thus, by moving the adjusting sleeve 25, the range of motion or support angle of the swing rod 241 can be changed, thereby increasing the distance between the first side support 22 and the second side support 23. This operation method is simple and intuitive, requiring no complicated tools or steps, and greatly improving the adjustment efficiency.

[0060] Furthermore, the support rod 21 is provided with a guide protrusion 212, which extends along the length of the support rod 21. The adjusting sleeve 25 has a guide groove 251 that cooperates with the guide protrusion 212. The sliding cooperation between the guiding groove 251 and the guide protrusion 212 limits the movement direction of the adjusting sleeve 25, preventing deviation and improving the smoothness and accuracy of movement. In this embodiment, the guide protrusion 212 extends along the vertical direction of the support rod 21.

[0061] Optionally, two guide protrusions 212 are provided, and the two guide protrusions 212 are located on opposite sides of the support rod 21. Similarly, two guide grooves 251 are provided, each corresponding to one of the guide protrusions 212.

[0062] In some embodiments, the side support assembly 20 further includes a buckle 26 and a first elastic member. The buckle 26 is rotatably connected to the adjusting sleeve 25. The buckle 26 has a snap-fit ​​head 261. The support rod 21 is provided with a slot 213 that cooperates with the snap-fit ​​head 261. The two ends of the first elastic member are correspondingly connected to the buckle 26 and the adjusting sleeve 25. When the adjusting sleeve 25 is in the first position, the snap-fit ​​head 261 snaps into the slot 213.

[0063] Specifically, the engaging head 261 is a key component of the locking member 26, and its shape and size match the locking groove 213 on the support rod 21. The locking member 26 is rotatably connected to the adjusting sleeve 25, allowing the locking member 26 to rotate relative to the adjusting sleeve 25 to a certain extent. This enables the engaging head 261 to engage and disengage from the locking groove 213 on the support rod 21, ensuring that the locking member 26 can securely fix the adjusting sleeve 25 to the position on the support rod 21 when needed. The two ends of the first elastic member are connected to the locking member 26 and the adjusting sleeve 25 respectively, so that the locking member 26 can be subjected to the action of the first elastic member during rotation, realizing the automatic engagement and disengagement of the engaging head 261 from the locking groove 213.

[0064] Optionally, the first elastic element may be made of a spring or other elastic material to ensure a stable elastic force and to ensure that the snap fastener 26 has good elasticity and reliability during operation.

[0065] The buckle 26 and the first elastic member form a fixing and adjustment mechanism for the adjusting sleeve 25. This can be understood as follows: when the adjusting sleeve 25 is in the first position, the locking head 261 engages with the slot 213 on the support rod 21 under the action of the first elastic member, allowing the adjusting sleeve 25 to be firmly fixed in the first position, ensuring that the opening width between the first side support 22 and the second side support 23 remains A. At this time, the side support assembly 20 of the shoe support is in a slightly open state, suitable for narrower shoes or convenient for shoes to be fitted onto the adjustable shoe support provided by this utility model.

[0066] When it is necessary to switch the adjusting sleeve 25 from the first position to the second position, the user only needs to apply a certain external force to the buckle 26 to overcome the elastic force of the first elastic element, causing the locking head 261 to separate from the slot 213. Then, the user can slide the adjusting sleeve 25 to the second position. After the adjusting sleeve 25 reaches the second position, the locking head 261, under the action of the first elastic element, engages again into another slot 213 on the support rod 21, thereby fixing the adjusting sleeve 25 in the second position. At this time, the opening width between the first side support 22 and the second side support 23 becomes B, suitable for wider shoes.

[0067] It should be noted that in this embodiment, only one slot 213 is provided to ensure the structural strength of the support rod 21. That is, the slot 213 can correspond to the adjusting sleeve 25 at the first position; when the adjusting sleeve 25 moves from the first position to other positions, the engaging head 261 will move out of the slot 213 and abut against the outer wall surface of the support rod 21 under the action of the first elastic element, so that the opening width of the side support assembly 20 can be infinitely varied between A and B, thereby more flexibly adapting to the width requirements of various shoes.

[0068] Of course, in some embodiments, multiple slots 213 may be provided, and the slots 213 may correspond one-to-one with the positions of the adjusting sleeves 25 on the support rods 21.

[0069] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the latching member 26 includes a rotating shaft 262 and a pressing part 263. The pressing part 263 and the engaging head 261 are located on opposite sides of the rotating shaft 262, and the rotating shaft 262 is connected to the adjusting sleeve 25. When it is necessary to adjust the opening width of the side support assembly 20, the user only needs to press the pressing part 263, and the engaging head 261 will disengage from the slot 213 of the support rod 21; at this time, the adjusting sleeve 25 can slide freely along the support rod 21 until it moves to the desired target position.

[0070] In this embodiment, the fastener 26 includes a plate-shaped body 264 with a through hole 2642. A rotating shaft 262 is disposed within the through hole 2642, and an adjusting sleeve 25 has a shaft hole that matches the rotating shaft 262, thereby realizing a rotatable connection between the fastener 26 and the adjusting sleeve 25 and providing a stable fulcrum for the rotation of the fastener 26. Both the engaging head 261 and the pressing part 263 are provided as protrusion-shaped structures. The plate-shaped body 264 has a first surface and a second surface facing each other. The engaging head 261 is disposed on one of the first surface and the second surface, and the pressing part 263 is disposed on the other of the first surface and the second surface.

[0071] When the user needs to adjust the opening width of the side support assembly 20, they simply press the pressing part 263 with their finger. When the pressing part 263 is subjected to external force, it drives the latch 26 to rotate around the rotation axis 262, causing the locking head 261 to disengage from the slot 213. Once the locking head 261 disengages from the slot 213, the adjusting sleeve 25 is no longer fixed, and the user can freely slide the adjusting sleeve 25 along the support rod 21 until it reaches the desired target position.

[0072] Furthermore, the cross-sectional area of ​​the locking head 261 gradually decreases from the plate body towards the far end, that is, the locking head 261 has a small end, which makes it easy for the locking head 261 to be locked into the slot 213, ensuring a stable connection and reducing shaking or loosening caused by the mating gap.

[0073] like Figure 5 and Figure 6 As shown, in some embodiments, the adjusting sleeve 25 includes a first sleeve 252 and a second sleeve 253. The first sleeve 252 has a large-diameter section 2521 and a small-diameter section 2522 connected to each other. The small-diameter section 2522 is provided with a slot 2523, and the fastener 26 is rotatably disposed in the slot 2523. The second sleeve 253 is sleeved on the outside of the small-diameter section 2522 and is aligned with the outer surface of the large-diameter section 2521.

[0074] Specifically, the large-diameter section 2521 and the small-diameter section 2522 of the first sleeve 252 both have the same inner diameter, which matches the outer diameter of the support rod 21, thus allowing the first sleeve 252 to be stably fitted onto the support rod 21. The outer diameter (outer circumference) of the small-diameter section 2522 of the first sleeve 252 is smaller than the outer diameter (outer circumference) of the large-diameter section 2521, so that when the second sleeve 253 is fitted onto the small-diameter section 2522 of the first sleeve 252, the outer surfaces of the first sleeve 252 and the second sleeve 253 are aligned, making the overall structure more compact and aesthetically pleasing.

[0075] Furthermore, a shaft hole is provided on the side wall of the slot 2523. The fastener 26 is rotatably connected to the shaft hole on the side wall of the slot 2523 via a rotating shaft 262. The slot space of the slot 2523 is larger than the size of the fastener 26 to ensure that the fastener 26 can rotate within the slot 2523. A pressing groove 2531 is provided on the second sleeve 253. The second sleeve 253 is fitted onto the small diameter section 2522 to close the opening of the slot 2523, protecting the fastener 26 and the rotating shaft 262 and preventing dust or other impurities from entering, thereby extending the service life of the components. The pressing part 263 of the fastener 26 is located within the pressing groove 2531, exposed to the outside environment, for convenient pressing operation by the user.

[0076] Furthermore, the fastener 26 is provided with a receiving groove 2641, one end of the first elastic member abuts against the receiving groove 2641, and the other end of the second elastic member abuts against the inner wall of the second sleeve 253. It should be noted that the first elastic member is not shown in the accompanying drawings of this application.

[0077] like Figure 2 and Figure 3 As shown, in some embodiments, at least one of the heel portion 11 and the toe portion 13 is provided with a guide block 14, the guide block 14 having a first guide ramp 141, and the adjusting sleeve 25 having a second guide ramp 254 that cooperates with the first guide ramp 141. When the adjusting sleeve 25 moves from the second position to the first position, the adjusting sleeve 25 moves toward the support body 10, and the second guide ramp 254 pushes against the first guide ramp 141, causing the toe portion 13 and the heel portion 11 to move toward each other.

[0078] In other words, while adjusting the support width of the side support assembly 20, the length of the support body 10 can be adjusted through the cooperation of the first guide slope 141 and the second guide slope 254, so as to achieve synchronous adjustment of the two and improve the convenience of adjustment.

[0079] Furthermore, the guide block 14 has a high end 142 and a low end 143 on the first guide slope 141. The high end 142 is located above the low end 143, and the low end 143 is farther away from the middle portion 12 relative to the high end 142. That is, as the adjusting sleeve 25 moves toward the support body 10, reducing the support width of the side support assembly 20, the interaction between the first guide slope 141 and the second guide slope 254 allows the heel portion 11 and / or the toe portion 13 to move toward the middle portion 12, reducing the length of the support body 10. The process of the adjusting sleeve 25 moving away from the support body 10 adjusts the support width of the side support assembly 20 and the length of the support body 10 in the opposite way to the above process, and will not be described again.

[0080] Furthermore, two guide blocks 14 may be provided, with the two guide blocks 14 spaced apart or side by side along the width direction of the support body 10, making the adjustment process more stable and reducing shaking or uneven deformation caused by single-point force.

[0081] like Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the middle part 12 is provided with a synchronizing gear 122, the heel part 11 is provided with a first rack 112, and the toe part 13 is provided with a second rack 131. The first rack 112 and the second rack 131 are located on opposite sides of the synchronizing gear 122, and both the first rack 112 and the second rack 131 mesh with the synchronizing gear 122. When the synchronizing gear 122 rotates, the first rack 112 and the second rack 131 will move at the same speed and direction, thereby achieving synchronous adjustment of the heel part 11 and the toe part 13.

[0082] Furthermore, the support body 10 also includes a second elastic member, one end of which is connected to the middle part 12, and the other end of which is connected to the heel part 11 and / or the toe part 13.

[0083] When the shoe support is in its initial position, the second elastic element is in its natural state or a preset stretched / compressed state. At this time, the distance between the heel 11 and the toe 13 is the initial set value. The user drives the synchronous gear 122 to rotate by operating the adjustment sleeve 25 or other adjustment mechanism, thereby driving the first rack 112 and the second rack 131 to move. During this process, the heel 11 and the toe 13 will move towards or away from each other. As the heel 11 and the toe 13 move, the second elastic element will be stretched or compressed, storing elastic potential energy. This elastic force not only provides a restoring force but also enhances the stability of the adjustment process.

[0084] Furthermore, a second elastic element is connected between the toe cap 13 and the middle portion 12. That is, one end of the second elastic element is connected to the middle portion 12, and the other end of the second elastic element is connected to the toe cap 13. It should be noted that the second elastic element is not shown in the accompanying drawings of this application.

[0085] Optionally, the second elastic element may be made of a spring or other elastic material to ensure a stable elastic force and good elasticity and reliability during operation.

[0086] In this embodiment, the guide block 14 is disposed on the heel portion 11. The adjusting sleeve 25 can drive the heel portion 11 to move through the first guide ramp 141 and the second guide ramp 254, and then drive the toe portion 13 to move synchronously through the meshing transmission of the first rack 112, the second rack 131 and the synchronous gear 122.

[0087] Furthermore, the intermediate part 12 includes a main board 123 and a guide sleeve 124. The guide sleeve 124 is detachably installed on the main board 123. The gear shaft 1221 of the synchronous gear 122 is rotatably connected to the guide sleeve 124. The guide sleeve 124 is provided with a first guide groove 1241 and a second guide groove 1242. The first guide groove 1241 and the second guide groove 1242 are respectively located on both sides of the synchronous gear 122. The first guide groove 1241 and the second guide groove 1242 both extend along the length direction of the main board 123. The first rack 112 is slidably disposed in the first guide groove 1241, and the second rack 131 is slidably disposed in the second guide groove 1242 to ensure that the heel part 11 and the toe part 13 move in a predetermined direction.

[0088] like Figure 3 and Figure 8 As shown, in some embodiments, the support body 10 further includes an upper support 15 and a third elastic member 17. The upper support 15 is rotatably connected to the toe of the shoe 13, one end of the third elastic member 17 abuts against the upper support 15, and the other end of the third elastic member 17 abuts against the toe of the shoe 13.

[0089] Specifically, the main function of the shoe support 15 is to support the upper part of the shoe. The shoe support 15 is mounted on the toe box 13 via a rotating connection, allowing it to be flexibly adjusted according to the shape and size of the shoe for a better fit. The third elastic element provides a certain amount of elasticity, allowing the shoe support 15 to be fine-tuned according to the shape and size of the shoe for an even better fit. In other words, when the shoe support 15 is subjected to external force (such as when inserting or removing the shoe), the elasticity of the third elastic element helps the shoe support 15 automatically return to its initial position, ensuring the proper functioning of the shoe tree.

[0090] Furthermore, the shoe upper support 15 includes a first support body 151, a second support body 152, and a connector 153. Both the first support body 151 and the second support body 152 are elongated. The first support body 151 is rotatably connected to the shoe toe 13. The first support body 151 is provided with a positioning groove 1511. The second support body 152 is provided with an insertion part 1521 that cooperates with the positioning groove 1511. The connector 153 is correspondingly connected to the first support body 151 and the second support body 152 to fix the two together and facilitate the flexible adjustment of the second support body 152 within the positioning groove 1511.

[0091] In the initial state, the insertion part 1521 of the second support 152 is inserted into the positioning groove 1511 of the first support 151, and the connector 153 (threaded post) fixes the first support 151 and the second support 152 together through the threaded hole. When it is necessary to adjust the shape or size of the shoe upper support 15 to better fit the shoe upper, the user can loosen the connector 153 (threaded post) and move the second support 152 to the appropriate position along the positioning groove 1511. After selecting a suitable threaded hole position, the first support 151 and the second support 152 are fixed together again using the connector 153 (threaded post).

[0092] Furthermore, the connector 153 can be configured as a threaded post, and the first connector is provided with a threaded hole that mates with the threaded post. Multiple threaded holes can be provided and arranged at intervals along the extension direction of the positioning slide groove 1511.

[0093] like Figure 8 As shown, in some embodiments, the heel portion 11, the middle portion 12, and the toe portion 13 are all provided with hollow cavities 16. The hollow cavities 16 are used to store cleaning media. The surfaces of the heel portion 11, the middle portion 12, and the toe portion 13 are all provided with spray holes 161, which are used to spray the cleaning media from the hollow cavities 16 into the shoe's inner cavity. In other words, the hollow cavities 16 provide storage space for the cleaning media, allowing the shoe tree to release the cleaning media at any time during use, meeting the shoe's cleaning and maintenance needs. The spray holes 161 evenly spray the cleaning media into the shoe's inner cavity, thereby achieving cleaning, deodorization, or care of the shoe's interior. The design of the spray holes 161 not only ensures the uniform distribution of the cleaning media but also improves the cleaning and maintenance effect.

[0094] like Figure 1 As shown, in some embodiments, the adjustable shoe support 100 further includes a bracket 27, which includes a rotating disk 271. The rotating disk 271 has a first protrusion 272 and a second protrusion 273, which are symmetrically arranged around the axis of rotation of the rotating disk 271. Both the support body 10 and the side support assembly 20 can be provided in pairs, and are fixed to the first protrusion 272 and the second protrusion 273 by the support rod 21 of the support body 10.

[0095] In addition, such as Figure 10 As shown, one embodiment of the present invention provides a shoe cleaning device, which includes the adjustable shoe support provided in any of the above embodiments.
