Description

TECHNICAL FIELD

[0001] The present application relates to the field of shoe drying, in particular to a shoe drying device. BACKGROUND

[0002] In daily life, the problem of moisture caused by rain, wading or long-term wearing is very common. As a key equipment to solve this problem, shoe drying device has been widely used in family, outdoor camp, sports venues and other scenes. However, the hot air or normal temperature air flow used for drying in the traditional shoe drying device can only be continuously blown to the inside of the shoe in a single fixed direction. This fixed direction airflow delivery mode makes the airflow only cover the local area directly opposite to the airflow outlet in the inside of the shoe. For the parts such as the front end of the toe and the inside of the heel, which the airflow is difficult to directly reach, the drying effect is greatly reduced, forming an obvious drying blind area, and the uniform drying of the whole inside of the shoe cannot be realized.

[0003] In addition to the problem of fixed airflow direction, the existing shoe drying equipment generally lacks a positioning and opening structure for the shoe. During the drying process, the shoe can only be naturally placed in the drying position, and a semi-closed cavity is formed in the inside of the shoe which is not opened. Because the upper and the sole, the upper and the tongue, the inside of the shoe body and the insole are closely attached, the gap for airflow circulation is very small. Even if hot air is sent into the inside of the shoe, it is also difficult to penetrate into these closely attached core areas. At the same time, after the wet shoe is heated, the humid air formed by the evaporation of the internal moisture is limited by the structure of the semi-closed cavity and cannot be quickly discharged outward. It can only be repeatedly circulated after mixing with the incoming airflow, forming a local high-humidity circulation state, which further hinders the moisture absorption capacity of the subsequent airflow.

[0004] The superposition of local high-humidity circulation and drying blind area directly leads to the uneven drying problem that the surface is dry but the inside is still wet in the existing equipment. When users use it, they often find that the surface of the shoe and the shoe opening part have shown dry state, but when wearing, they can still feel the moisture of the toe, the upper and the heel, which not only affects the wearing comfort, but also may breed bacteria, produce odor, and even damage the material of the shoe. Therefore, it is necessary to design a shoe drying device to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0046] In order to further understand the features, technical means and specific purposes and functions of the present application, the present application is described in detail below in combination with the drawings and specific embodiments.

[0047] A shoe drying device comprises:

[0048] A hot air gun 2 is arranged inside the frame 1, and the output end of the hot air gun 2 is arranged upward and fixedly connected with a main air cylinder 3. The main air cylinder 3 is arranged with branch pipes 4 at intervals on one side. The lower end of the branch pipe 4 is arranged with a supporting table 7 fixedly connected with the main air cylinder 3.

[0049] The upper end of the supporting table 7 is arranged with a clamping mechanism for three-point clamping and positioning of the outside of the shoe. The clamping mechanism comprises a main roller 8 arranged on one side of the branch pipe 4 and a secondary roller 12 arranged on the other side of the branch pipe 4. The upper side of the branch pipe 4 is arranged with an auxiliary roller 10.

[0050] The supporting mechanism is arranged beside the branch pipe 4 and supports the shoe from inside to outside, and the supporting mechanism comprises a rotating cylinder 23 arranged on one side of the branch pipe 4 close to the main roller 8, the rotating cylinder 23 is arranged with supporting frames 35 at equal angles in the circumferential direction, and two hollow cams 45 are arranged on the two sides of the rotating cylinder 23 respectively, and the hollow cams 45 are coaxially connected with the branch pipe 4.

[0051] When the device is in operation, the vamp of the shoe is arranged downward, and the heel is placed to the direction of the secondary roller 12 outside the rotating cylinder 23, at this time, the main roller 8, the auxiliary roller 10 and the secondary roller 12 in the clamping mechanism clamp the outside of the shoe from three points, so that the shoe can be kept stable during the drying process, then in order to support the inside of the shoe, the supporting frames 35 in the supporting mechanism will apply a supporting force to the inside of the shoe from inside to outside when the rotating cylinder 23 rotates, so as to avoid that the vamp and the insole, the upper and the tongue of the shoe are closely attached during the drying process of the shoe, and then the hot air flow can only act on the surface of the shoe, and it is difficult to enter the core area such as the toe and the inside of the heel. After the humid air evaporates, it cannot be quickly discharged, forming a local high humidity cycle, resulting in uneven drying problem that the surface is dry while the inside is still humid.

[0052] In order to support the heel, the two hollow cams 45 will be deflected after the shoe is positioned by the clamping mechanism, and then the heel is supported to realize the complete circulation of hot air, thereby improving the drying efficiency of the shoe.

[0053] In order to limit the main roller 8, the auxiliary roller 10 and the secondary roller 12, so as to elastically position the shoe, the following features are further provided:

[0054] As shown in Figure 3 and Figure 4 , the two sides of the main roller 8 are respectively provided with first roller frames 9, the first roller frames 9 are slidably connected with the base fixed to the upper end of the support table 7 through springs, the first roller frames 9 are fixed to the end of the main roller 8, and when the shoe is installed outside the rotating cylinder 23, the main roller 8 applies a supporting force to the vamp of the shoe from bottom to top;

[0055] The two ends of the auxiliary roller 10 are respectively provided with second roller frames 11, the second roller frames 11 are slidably connected with the roller seat fixed to the upper end of the support table 7 through tension springs, the second roller frames 11 are fixed to the end of the auxiliary roller 10, and when the shoe is installed outside the rotating cylinder 23, the auxiliary roller 10 applies a supporting force to the insole of the shoe from top to bottom;

[0056] The two ends of the secondary roller 12 are respectively provided with third roller frames 13, the third roller frames 13 are hingedly connected with the support fixed to the upper end of the support table 7 through torsional springs, the third roller frames 13 are fixed to the end of the secondary roller 12, and when the shoe is installed outside the rotating cylinder 23, the secondary roller 12 applies a supporting force to the heel of the shoe in a diagonal direction.

[0057] On the basis of three-point clamping of the main roller 8, the auxiliary roller 10 and the secondary roller 12, elastic positioning is achieved through the setting of different elastic components. The spring between the first roller frame 9 and the base can adaptively expand and contract with the shoe upper curvature, so that the main roller 8 always adheres to the shoe upper and maintains appropriate pressing force; the tension spring of the second roller frame 11 can pull the auxiliary roller 10 to tightly press the shoe sole, avoiding the up-and-down movement of the shoe during drying; the torsional spring of the third roller frame 13 allows the secondary roller 12 to adjust the angle according to the heel size, so that the shoe is stably pressed without being squeezed and deformed, meeting the positioning needs of different sizes of shoes.

[0058] In order to prevent damage to the shoes and improve the pressing force of the clamping mechanism on the shoes, the following features are also provided:

[0059] As shown in Figure 4 and Figure 6 , the outer parts of the main roller 8, the auxiliary roller 10 and the secondary roller 12 are respectively fixedly connected with rubber sleeves 14, which are formed with anti-skid grooves 15 at equal angles in the circumferential direction.

[0060] At the key parts of the clamping mechanism in contact with the shoes, the setting of the rubber sleeves 14 effectively avoids scratches or wear caused by direct contact of the metal roller body with the shoe upper, especially for various shoe materials such as leather and fabric. At the same time, the anti-skid grooves 15 on the surface of the rubber sleeves 14 can increase the friction with the surface of the shoe. When the rotating drum 23 rotates to drive the shoe slightly, it prevents slipping between the shoe and the roller body, ensures the stability of three-point clamping, and makes the shoe always maintain the preset position during the drying process, thereby guaranteeing the opening and drying effects.

[0061] In order to realize the rotation of the rotating drum 23, the following features are also provided:

[0062] As shown in Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the opening mechanism further comprises a first motor 16 fixedly connected with the end of the branch pipe 4, the main gas port 5 is formed in the side wall of the branch pipe 4, the main gas port 5 is coaxially arranged with the rotating drum 23, the first bevel gear set 17 is fixedly connected inside the branch pipe 4, one side of the first bevel gear set 17 is coaxially fixedly connected with the output end of the first motor 16, the rotating shaft 18 is coaxially fixedly connected with the rotating drum 23, and the other side of the first bevel gear set 17 is coaxially fixedly connected with the rotating shaft 18.

[0063] The end of the rotating drum 23 away from the branch pipe 4 is fixedly connected with a drum cover 25, the drum cover 25 is coaxially fixedly connected with the rotating shaft 18, the outer part of the rotating drum 23 is coaxially provided with a positioning frame 19, the positioning frame 19 is fixedly connected with the side wall of the branch pipe 4, and the rotating drum 23 is rotationally connected with the positioning frame 19.

[0064] When the expansion mechanism needs to drive the rotating drum 23 to rotate, the first motor 16 drives the rotating shaft 18 to rotate through the first bevel gear set 17, and then drives the rotating drum 23 fixedly connected with the rotating shaft 18 to rotate. The coaxial design of the main air port 5 and the rotating drum 23 ensures that the airflow delivered by the hot air gun 2 can accurately enter the inside of the rotating drum 23; the positioning frame 19 cooperates with the drum cover 25 to form stable support on both ends of the rotating drum 23, avoiding shaking of the rotating drum 23 during rotation, and ensuring the stability of the operation of the expansion mechanism, while providing a stable carrier for the subsequent expansion of the support frame 35.

[0065] In order to supplement the specific structure of the positioning frame 19, the following features are further provided:

[0066] As shown in Figure 7 and Figure 8 , the positioning frame 19 includes a bottom disc 22 fixedly connected with the side wall of the branch pipe 4, and the drum cover 25 is coaxially provided with a top disc 20, and the side of the top disc 20 close to the bottom disc 22 is provided with guide shafts 21 arranged at equal angles in the circumferential direction;

[0067] One end of the guide shaft 21 is fixedly connected with the top disc 20, and the other end is fixedly connected with the bottom disc 22.

[0068] On the basis of the positioning frame 19 achieving stable support of the rotating drum 23, the bottom disc 22 is fixedly connected with the branch pipe 4 to form a fixed base, and the top disc 20 is connected with the bottom disc 22 through the guide shafts 21 to form a frame structure. The guide shafts 21 arranged at equal angles not only enhance the overall rigidity of the positioning frame 19, but also provide accurate guidance for the subsequent sliding of the guide seat 33, ensuring that the guide seat 33 always moves in the axial direction during movement, avoiding uneven expansion of the support frame 35 due to deviation, and ensuring the uniformity of the expansion of the inside of the shoe.

[0069] In order to facilitate the hot air passing through the rotating drum 23 to be uniformly sprayed into the inside of the shoe, the following features are further provided:

[0070] As shown in Figure 8 , the rotating drum 23 is formed with air holes 24 arranged at equal angles in the circumferential direction, and the drum cover 25 is formed with leakage holes 26 arranged at equal angles in the circumferential direction.

[0071] After the airflow delivered by the hot air gun 2 enters the rotating drum 23, the air holes 24 in the circumferential direction of the rotating drum 23 enable the airflow to be sprayed from multiple directions into the inside of the shoe, breaking the limitation of traditional fixed-direction airflow; the leakage holes 26 of the drum cover 25 further expand the coverage range of the airflow, so that the toe part of the shoe can also obtain sufficient hot air. The design of equal-angle array ensures that the airflow is uniformly distributed in the inside of the shoe, avoiding local airflow concentration or deficiency, and cooperating with the rotation of the rotating drum 23 to realize hot air coverage of the entire inside of the shoe, solving the problem of drying blind area.

[0072] In order to realize that the push rod 34 can open the inside of the shoes in the process of the rotation of the rotating drum 23, so that the hot air in the rotating drum 23 can uniformly dry the shoes, the following features are further provided:

[0073] As shown in Figure 5 , Figure 7 、 Figure 8 and Figure 10 , the bottom disc 22 is provided with the first strong magnetic block 30 in the circumferential direction at equal angles, the first strong magnetic block 30 is rotationally connected with the bottom disc 22, the rotating drum 23 is coaxially fixedly connected with the first gear ring 27, the first strong magnetic block 30 is coaxially fixedly connected with the first gear 28, and the first gear 28 is engaged with the first gear ring 27;

[0074] The bottom disc 22 is fixedly connected with the tray 29 away from the branch pipe 4, the tray 29 is rotationally provided with the second strong magnetic block 31 in the circumferential direction at equal angles, the second strong magnetic block 31 is coaxially arranged with the first strong magnetic block 30 and is connected through magnetic power transmission, the second strong magnetic block 31 is coaxially fixedly connected with the screw rod 32, one end of the screw rod 32 away from the second strong magnetic block 31 is rotationally connected with the top disc 20, and the screw rod 32 is drivingly connected with the guide seat 33 through a screw sleeve, and the guide seat 33 is slidingly connected with the guide shaft 21;

[0075] The guide seat 33 is provided with the push rod 34 on both sides, one end of the push rod 34 is rotationally connected with the guide seat 33, the other end is rotationally connected with the support frame 35, and one end of the support frame 35 close to the top disc 20 is rotationally connected with the top disc 20.

[0076] When the rotating drum 23 rotates, the first ring gear 27 fixedly connected thereto drives the meshed first gear 28 to rotate, and in turn drives the first strong magnetic block 30 to rotate, thereby driving the second strong magnetic block 31 on the tray 29 to rotate synchronously through magnetic transmission, and driving the screw rod 32 to rotate. When the screw rod 32 rotates, the sleeve drives the guide base 33 to slide along the guide shaft 21, and the guide base 33 pushes the push rod 34 during the movement, so that the support frame 35 hinged to the top plate 20 rotates around the hinge point, and the shoe is expanded from the inside out. In this process, because the inside of the shoe is an irregular curved surface space, each support frame 35 needs to adapt to the profile of different areas, and the maximum expandable range is different. The magnetic transmission has the characteristic of non-rigid linkage. When a support frame 35 moves with the guide base 33 to the limit abutting position abutting against the inner profile of the shoe, the support frame 35 cannot continue to expand outward, and the corresponding screw rod 32 and second strong magnetic block 31 stop rotating. However, the rotating drum 23 still drives the first ring gear 27, the first gear 28 and the first strong magnetic block 30 to continue to rotate, and at this time, the first strong magnetic block 30 and the second strong magnetic block 31 that have stopped rotating produce relative sliding rotation, thereby avoiding rigid extrusion damage to the support frame 35 and the shoe material. In this way, each support frame 35 can independently move to the limit abutting position under the self-adaptive adjustment of the magnetic transmission, and finally realize the complete expansion of the inside of the shoe, thereby providing sufficient and uniform space for airflow circulation. The structure cooperates mechanical transmission and magnetic transmission to accurately match the rotation of the rotating drum 23 with the self-adaptive expansion of the support frame 35.

[0077] In order to prevent the support frame 35 from affecting the drying process of the shoe after expansion, the following features are further provided:

[0078] As shown in Figure 10 , the middle part of the support frame 35 is formed with an avoidance strip hole 36 for avoiding hot air, and the two sides of the avoidance strip hole 36 are respectively provided with a rubber strip 37 which is fixedly connected with the support frame 35.

[0079] After the support frame 35 expands the shoe from the inside out, the avoidance strip hole 36 in the middle part reserves a flow channel for hot air, so as to avoid that the support frame 35 blocks the airflow and causes local insufficient drying, and to ensure that the hot air can pass through the support frame 35 to reach each area inside the shoe. The rubber strips 37 on the two sides play a buffering role when the support frame 35 contacts the inside of the shoe, preventing the support frame 35 from rigidly contacting and damaging the material inside the shoe, and increasing the friction force to prevent the support frame 35 from shifting when the shoe rotates, thereby ensuring the stability of the expanded state.

[0080] In order to adapt to the shape of the inside of the shoe, the following features are further provided:

[0081] As shown in Figure 10 , the two sides of the support frame 35 are respectively provided with a clamping plate 39, the middle part of the clamping plate 39 is formed with a strip-shaped limiting hole 40, and the two sides of the support frame 35 are respectively provided with a screw 41 which is screwed with the support frame 35 after penetrating through the strip-shaped limiting hole 40.

[0082] The side of the clamping plate 39 away from the support frame 35 is provided with an auxiliary frame 38, the side of the auxiliary frame 38 close to the support frame 35 is fixedly connected with the clamping plate 39, and the side of the auxiliary frame 38 away from the support frame 35 is arc-shaped.

[0083] On the basis that the support frame 35 adapts to the basic contour of the shoe, the clamping plate 39 can be adjusted in position along the support frame 35 through the strip-shaped limiting hole 40, and the position of the clamping plate 39 is fixed after the bolt 41 is screwed, so that the auxiliary frame 38 can adjust the spacing according to the internal width of the shoe. The auxiliary frame 38 designed in an arc shape is attached to the arc-shaped contour in the shoe, increases the contact area with the shoe, makes the opening force more uniform, avoids local excessive stress leading to deformation of the shoe type, and at the same time adapts to the internal structure of different shoe types, improves the universality of the device.

[0084] In order to drive the hollow cam 45 to rotate, the following features are further provided:

[0085] As shown in Figure 5 , Figure 8 , Figure 9 , Figure 11 and Figure 12 , two sides of the main gas port 5 are respectively formed with a secondary gas port 6, the side of the secondary gas port 6 is formed with an avoiding perforation 46, two second gear rings 44 are rotatably connected inside the branch pipe 4, the second gear rings 44 are arranged inside the avoiding perforation 46, the side of the second gear rings 44 close to the center is provided with a second gear 43, the second gear 43 is engaged with the second gear ring 44, and the two second gears 43 are coaxially arranged;

[0086] The side of the first motor 16 is provided with a second motor 42, the output end of the second motor 42 is sequentially fixedly connected with the two second gears 43 coaxially, the second gear ring 44 is coaxially arranged with the hollow cam 45, the avoiding perforation 46 is provided with a short pin 47, one end of the short pin 47 is fixedly connected with the second gear ring 44, and the other end of the short pin 47 is fixedly connected with the inner wall of the hollow cam 45 after passing through the avoiding perforation 46.

[0087] After the shoe is clamped and positioned, the second motor 42 drives the two coaxial second gears 43 to rotate, the second gear 43 drives the engaged second gear ring 44 to rotate, and the second gear ring 44 drives the hollow cam 45 to deflect around the axis of the branch pipe 4 through the short pin 47. The arrangement of the secondary gas port 6 ensures that the hollow cam 45 does not affect the airflow delivery when it deflects, and the avoiding perforation 46 provides movement space for the short pin 47. The deflection of the hollow cam 45 can accurately abut against the inside of the heel, open the heel part, break the closed state at the heel, enable hot air to enter the core area of the heel, and accelerate the discharge of humid air.

[0088] The detailed working principle of the device is as follows:

[0089] First, the shoes are put on the outside of the rotating drum 23 with the vamp down and the heel towards the secondary roller 12 direction, at this time the clamping mechanism is automatically started positioning-the main roller 8 is pressed against the vamp from bottom to top by the spring force of the first roller frame 9, the secondary roller 10 is pressed against the sole from top to bottom by the tension of the second roller frame 11, and the secondary roller 12 is obliquely pressed against the heel by the torsional force of the third roller frame 13, forming three-point elastic clamping, ensuring that the shoes are stable and not deformed during drying. Subsequently, the expanding mechanism starts to work, the first motor 16 is started to drive the rotating shaft 18 to rotate through the first bevel gear set 17, so that the rotating drum 23 rotates synchronously; when the rotating drum 23 rotates, the first gear ring 27 fixedly connected thereto drives the first gear 28 to rotate, driving the first strong magnetic block 30 to rotate, and the second strong magnetic block 31 rotates synchronously through magnetic transmission, and then driving the screw rod 32 to rotate, the screw sleeve drives the guide base 33 to slide along the guide shaft 21, the guide base 33 pushes the push rod 34 to make the support frame 35 rotate around the hinge point of the top disc 20, and the shoes are expanded from inside to outside, the avoiding strip hole 36 of the support frame 35 reserves a hot air passage, and the rubber strip 37 avoids damaging the shoe material. At the same time, the second motor 42 is started to drive the two second gears 43 to rotate, driving the second gear ring 44 to rotate, and driving the hollow cam 45 to deflect through the short pin 47, and pressing against the inside of the heel to complete the expansion of the heel. The airflow generated by the hot air gun 2 enters the rotating drum 23 through the main air cylinder 3 and the main air port 5 of the branch pipe 4, and is uniformly sprayed into the shoes through the air holes 24 of the rotating drum 23 and the leakage holes 26 of the cylinder cover 25. The continuous rotation of the rotating drum 23 makes the airflow cover the core areas such as the toe and the heel in all directions; the heel expanded by the hollow cam 45 and the shoe body expanded by the support frame 35 form a smooth passage, and the humid air circulates and is discharged from the shoe opening along with the airflow, avoiding local high humidity circulation. During the whole process, the rubber sleeve 14 and the anti-skid groove 15 ensure that the shoes are linked with the rotating drum 23 synchronously, the auxiliary frame 38 adapts to the shape of the shoes to ensure uniform expansion, and the shoes are uniformly dried inside.
