Description

Technical Field

[0001] The present invention relates to the technical field of drying, and specifically to a rotary circulating air rapid drying towel box. Background Art

[0002] In the early days, most towel dryers were static heating, relying on natural ventilation or simple fans for moisture removal, with problems such as uneven drying and high energy consumption.

[0003] Existing towel drying uses circulating air + rotating structure. By introducing forced hot air circulation and a dynamic rotating mechanism, the drying time is shortened to 1 / 3 of the traditional method; existing rotary circulating air rapid drying towel boxes form a closed-loop hot air system through an internal circulating fan and heating elements (such as electric heating tubes). The fan drives hot air to flow at high speed inside the box. Combined with a specially designed air duct structure, it ensures that the hot air evenly covers the surface of the towel, accelerating water evaporation. This equipment is mainly used in places where towels are used frequently, and needs to quickly and efficiently complete towel drying and sterilization to ensure hygiene and turnover efficiency. Typical application scenarios include: hotels and guesthouses: rapid drying and sterilization of guest room towels and bath towels; bath centers and hot springs: circular treatment of a large number of wet towels; gyms and swimming pools: high-frequency use requirements for sports towels; hospitals and nursing homes: disinfection and drying of medical dressings or patient towels; catering industry: rapid drying of kitchen cleaning towels.

[0004] Currently, the rotary towel dryers on the market generally have problems of missing or insufficient sterilization functions, mainly manifested as: only relying on high-temperature drying: although high temperature can kill some bacteria, it has limited effect on stubborn microorganisms; and there are static irradiation dead angles. For some models equipped with UV lamps, due to fixed installation, the irradiation of towel folds is uneven, resulting in an increased hygiene risk.

[0005] Therefore, it is urgent to improve towel drying equipment to solve the above existing problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a rotary circulating air rapid drying towel box, which realizes the full-process automation of drying, sterilization, and cleaning through ingenious mechanical linkage, and at the same time has high efficiency and reliability.

[0007] To achieve the above purpose, the main technical solutions adopted by the present invention include: a towel dryer, which is composed of a box body, a drying tank, a hollow drum, a heating device, and a driving device. Hollow shafts rotatably connected to the box body are fixed on opposite sides of the hollow drum;

[0008] A functional module extending into the hollow drum is arranged inside the box body. The functional mechanism includes a sterilization structure arranged on the hollow drum and an adjustment mechanism arranged inside the box body for adjusting the sterilization structure;

[0009] The sterilization structure includes a sterilization cylinder disposed inside the hollow drum and a sterilization sleeve sleeved outside the hollow drum;

[0010] The adjustment mechanism is composed of a centrifugal adjustment structure and a wire winding structure. A transmission member is provided between the left hollow shaft and the centrifugal adjustment structure, and a pushing structure for moving the sterilization cylinder is provided below the centrifugal adjustment structure;

[0011] Installation disks are fixed on both the left and right sides of the hollow drum, and a guiding structure for rotating the sterilization cylinder is provided inside the left installation disk. A cleaning mechanism for cleaning the hollow drum is provided between the end of the sterilization cylinder away from the pushing structure and the inside of the box body.

[0012] By adopting the above technical solution, the present application can provide dual ultraviolet sterilization inside and outside, enhance the sanitary effect, and cooperate with the use of the centrifugal adjustment structure to automatically adjust the positions of the sterilization cylinder and the sterilization sleeve according to the rotation speed of the hollow drum, improving the flexibility and efficiency of sterilization.

[0013] Preferably, the drying tank is opened inside the box body and communicates with its front surface. The hollow drum is located inside the drying tank. The inside of the box body is hollowly arranged. The heating device is fixed on the top side of the box body and communicates with the drying tank;

An air extraction pipe rotatably connected to the right hollow shaft is fixed on the side of the casing away from the impeller. A filter cartridge is detachably installed on the air extraction pipe.

[0015] The beneficial effect of adopting the above further solution is that the drying tank communicates with the inside of the box body, and the heating device is fixed on the top side of the box body and communicates with the drying tank, so that hot air can smoothly enter the drying tank to uniformly heat the towel. At the same time, the rotation of the impeller further promotes the circulation of hot air inside the box body, improves the utilization rate of hot air, and thus speeds up the drying speed of the towel.

[0016] Preferably, an ultraviolet germicidal lamp is embedded in the sterilization sleeve. The transmission member includes a transmission gear fixed to the end of the left hollow shaft and a first driven gear meshing with the outside of the transmission gear. The guiding structure includes an elastic guide rod disposed inside the left mounting disc and a ball rotatably mounted at the bottom end of the elastic guide rod. An installation groove for installing the elastic guide rod is formed inside the left mounting disc, and the bottom side of the installation groove communicates with the outside. A guiding groove is formed inside the sterilization cylinder and is arranged around the outer surface. The ball is in rolling connection with the inner side of the guiding groove and cooperates with the movement of the pushing structure to make the sterilization cylinder rotate automatically.

[0017] The beneficial effect of adopting the above further scheme is that: through the cooperation of the elastic guide rod, the ball and the guiding groove, the sterilization cylinder can rotate automatically during the movement, which helps the towels to be evenly distributed in the sterilization cylinder and further improves the sterilization effect.

[0018] Preferably, the centrifugal adjustment structure includes a rotating shaft fixed to the outer surface of the first driven gear, a first connecting rod fixed to the top end of the rotating shaft, a sliding sleeve and a rotating sleeve sleeved on the outer surface of the rotating shaft, a swing arm hinged to the end of the first connecting rod, a gravity ball fixed to the other end of the swing arm, and a second connecting rod hinged between the swing arm and the rotating sleeve.

[0019] The beneficial effect of adopting the above further scheme is:

[0020] Preferably, the rotating sleeve is rotatably mounted on the outer surface of the sliding sleeve. The number of the swing arm, the gravity ball and the second connecting rod in the centrifugal adjustment structure is two, and the two swing arms are symmetrically arranged. A return spring is rotatably mounted between the sliding sleeve and the rotating shaft.

[0021] The beneficial effect of adopting the above further scheme is that when the rotating shaft rotates, due to the centrifugal force, the sliding sleeve will generate a radial displacement relative to the rotating shaft, which is transmitted to other parts of the equipment through the connecting frame and cooperates with the pushing structure to realize the reciprocating adjustment of the sterilization cylinder, so as to realize the adaptive adjustment of the operation state of the equipment.

[0022] Preferably, a connecting frame connected to the pushing structure is fixed to the outer surface of the bottom end of the sliding sleeve. The pushing structure includes a sliding plate slidably disposed inside the box body and fixed to one side of the connecting frame. An inclined chute is formed inside the sliding plate. A roller is in rolling connection with the inside of the chute. A shaft rod is fixed to the inside of the roller, and the other end of the shaft rod is fixed to a docking seat rotatably connected to the left hollow shaft.

[0023] The beneficial effect of adopting the above further scheme is that the rolling connection mechanism between the roller and the chute reduces the direct contact and wear between components, prolongs the service life of the equipment, and the docking seat where the shaft rod fixed to the inside of the roller is rotatably connected to the left hollow shaft ensures the precise control of the pushing structure during the movement.

A wire winding disc is detachably installed on the outer surface of the support shaft. A pull rope connected to the sterilization sleeve is wound around the wire winding disc.

[0025] The beneficial effect of adopting the above further solution is that through the meshing action of the docking shaft, the second driven gear and the rack, the power transmission and linkage between the sliding plate and the wire winding structure are realized. When the sliding plate moves, the rack drives the second driven gear to rotate, and then drives the docking shaft and the support shaft to rotate, realizing the automatic winding or unwinding of the wire winding disc, enabling the device to automatically adjust the length of the pull rope according to the movement of the sliding plate, thereby realizing the automatic control of the position of the sterilization sleeve without manual intervention, improving the automation degree and operation convenience of the device.

[0026] Preferably, the transmission assembly includes a docking shaft fixed to one end of the support shaft. A second driven gear is fixed to the other end of the docking shaft. A rack meshing with the second driven gear is fixed to the left side of the sliding plate.

[0027] The beneficial effect of adopting the above further solution is that the pull rope is fixedly connected to the connecting seat at the bottom of the sterilization sleeve, realizing the coordinated operation with the wire winding structure. When the wire winding structure winds or unwinds the wire, the pull rope will drive the sterilization sleeve to move, thereby realizing the automatic control of the position of the sterilization sleeve.

[0028] Preferably, connecting seats are fixed to the upper and lower sides of the two mounting discs and the upper and lower sides of the sterilization sleeve. The sterilization sleeve is located between the two connecting seats, and a guide rod passing through the inside of the middle two connecting seats is fixed between the left and right connecting seats;

[0029] Among them, a tension spring surrounding the outside of the bottom guide rod is fixed between the connecting seat at the bottom of the sterilization sleeve and the connecting seat at the bottom right. The end of the pull rope away from the wire winding disc is fixed to the outer surface of the connecting seat at the bottom of the sterilization sleeve.

[0030] The beneficial effect of adopting the above further solution is that through the fixation of the connecting seat and the guide rod, the sterilization sleeve is stably supported between the two mounting discs, reducing the shaking and deviation during the operation of the device. When the device stops running, the elastic force of the tension spring will make the sterilization sleeve automatically reset to the initial position. The automatic reset function ensures the continuous and stable operation of the device and reduces the need for manual intervention.

[0031] Preferably, the cleaning mechanism includes a cleaning brush disk detachably installed at the right end of the sterilization cylinder and a piston structure fixed to the inner bottom wall of the box body. A suction pipe is fixed to the outer surface of the sterilization sleeve. The piston structure includes a storage box fixed to the inner bottom wall of the box body, a valve pipe fixedly communicated with the top side of the storage box, and a plug pipe fixedly communicated with one side of the valve pipe. A piston block is reciprocatingly arranged in the plug pipe. Two check valves are elastically hinged inside the valve pipe. One side of the piston block is fixed with a third connecting rod extending outside the plug pipe. The other end of the third connecting rod is fixed to the outer surface of the connecting seat at the bottom of the sterilization sleeve. The top side of the valve pipe is flange-connected with a suction pipe communicated with the suction pipe.

[0032] The beneficial effect of adopting the above further scheme is that through the linkage of the piston structure with the connecting seat at the bottom of the sterilization sleeve and the suction pipe, the automatic cleaning of the inner wall of the sterilization cylinder is realized. When the sterilization sleeve moves, the piston block reciprocates in the plug pipe, and the residues on the inner wall of the sterilization cylinder are sucked into the storage box through the valve pipe and the suction pipe. The automatic cleaning function reduces the need for manual intervention and improves the cleaning efficiency. The operator does not need to manually clean the inner wall of the sterilization cylinder and can focus more on other operations of the equipment.

[0033] The present invention has at least the following beneficial effects:

[0034] 1. By combining the use of the sterilization cylinder and the sterilization sleeve, the present invention provides dual ultraviolet sterilization inside and outside, enhancing the sanitation effect. Coupled with the use of the centrifugal adjustment structure, the positions of the sterilization cylinder and the sterilization sleeve are automatically adjusted according to the rotation speed of the hollow drum, improving the flexibility and efficiency of sterilization.

[0035] 2. Through the cooperation of the elastic guide rod, the ball and the guide groove, the sterilization cylinder can automatically rotate during the movement process, which helps the towels to be evenly distributed in the sterilization cylinder and further improves the sterilization effect.

[0036] 3. When the rotating shaft rotates, due to the action of centrifugal force, the sliding sleeve will generate a radial displacement relative to the rotating shaft, which is transmitted to other parts of the equipment through the connecting frame and cooperates with the pushing structure to realize the reciprocating adjustment of the sterilization cylinder, thereby realizing the adaptive adjustment of the operating state of the equipment.

[0037] 4. The transmission component realizes the power transmission and linkage between the sliding plate and the wire winding structure through the meshing action of the docking shaft, the second driven gear and the rack. When the sliding plate moves, the rack drives the second driven gear to rotate, and then drives the docking shaft and the support shaft to rotate, realizing the automatic wire winding or unwinding of the wire winding disk, enabling the equipment to automatically adjust the length of the pulling rope according to the movement of the sliding plate, thereby realizing the automatic control of the position of the sterilization sleeve without manual intervention, improving the automation degree and operation convenience of the equipment.

[0038] 5. Through the linkage of the piston structure with the connecting seat at the bottom of the sterilization sleeve and the straw, the present invention realizes the automatic cleaning of the inner wall of the sterilization cylinder. When the sterilization sleeve moves, the piston block reciprocates in the plug tube, and the residues on the inner wall of the sterilization cylinder are sucked into the storage box through the valve tube and the suction tube.

[0051] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0052] Embodiment 1:

[0053] As Figure 1 - Figure 3As shown in the figure, the rotary circulating air rapid drying towel box provided in this embodiment includes a towel dryer 1, which is composed of a box body 101, a drying tank 102, a hollow drum 103, a heating device 104 and a driving device. Hollow shafts 106 rotatably connected to the box body 101 are fixed on opposite sides of the hollow drum 103; it should be noted that the drying tank 102 is opened inside the box body 101 and communicates with its front surface. The hollow drum 103 is located inside the drying tank 102. The inside of the box body 101 is hollowly arranged. The heating device 104 is fixed on the top side of the box body 101 and communicates with the drying tank 102; specifically, a sealing door 105 for blocking the drying tank 102 is hinged on the front surface of the box body 101. The driving device includes a driving motor 107 and a casing 108 fixed inside the box body 101. An impeller 109 is rotatably installed inside the casing 108. Synchronous shafts 110 are fixed on both the output shaft of the driving motor 107 and the impeller 109. Among them, a gear member 111 engaged with each other is provided between the synchronous shaft 110 on the driving motor 107 and the right hollow shaft 106. A synchronous structure 114 is provided between the two synchronous shafts 110. An air extraction pipe 112 rotatably connected to the right hollow shaft 106 is fixed on one side of the casing 108 away from the impeller 109. A filter cartridge 113 is detachably installed on the air extraction pipe 112. The drying tank 102 communicates with the inside of the box body 101. The heating device 104 is fixed on the top side of the box body 101 and communicates with the drying tank 102, so that hot air can smoothly enter the drying tank 102 to uniformly heat the towel. At the same time, due to the rotation of the impeller 109, the circulation of hot air inside the box body 101 is further promoted, the utilization rate of hot air is improved, and thus the drying speed of the towel is accelerated. A temperature control structure is installed on the box body 101.

[0054] Embodiment Two:

[0055] As Figure 1 、 Figure 3 - Figure 9 As shown in the figure, to improve the towel drying effect, a functional module extending into the hollow drum 103 is provided inside the box body 101. The functional mechanism includes a sterilization structure arranged on the hollow drum 103 and an adjustment mechanism arranged inside the box body 101 for adjusting the sterilization structure; specifically, the sterilization structure includes a sterilization cylinder 3 arranged inside the hollow drum 103 and a sterilization sleeve 4 sleeved outside the hollow drum 103. An ultraviolet germicidal lamp 41 is embedded in the sterilization sleeve 4. Provide double ultraviolet sterilization inside and outside to enhance the sanitation effect. Then, in combination with the use of the centrifugal adjustment structure, the positions of the sterilization cylinder 3 and the sterilization sleeve 4 are automatically adjusted according to the rotation speed of the hollow drum 103, improving the flexibility and efficiency of sterilization. It should be noted that the sterilization cylinder 3 can be transparent, and a UV ultraviolet germicidal lamp is installed inside it, or the number of UV ultraviolet germicidal lamps is multiple and they are installed at intervals on the outer surface of the sterilization cylinder 3.

[0056] To improve the sterilization effect, the adjustment mechanism consists of a centrifugal adjustment structure 8 and a wire winding structure 10. A transmission member is provided between the left hollow shaft 106 and the centrifugal adjustment structure 8, and a pushing structure 9 for moving the sterilization cylinder 3 is provided below the centrifugal adjustment structure 8. Specifically, the transmission member includes a transmission gear 6 fixed to the end of the left hollow shaft 106 and a first driven gear 7 meshing with the outside of the transmission gear 6. The centrifugal adjustment structure 8 includes a rotating shaft 801 fixed to the outer surface of the first driven gear 7, a first connecting rod 802 fixed to the top end of the rotating shaft 801, a sliding sleeve 803 and a rotating sleeve 804 sleeved on the outer surface of the rotating shaft 801, a swing arm 805 hinged to the end of the first connecting rod 802, a gravity ball 806 fixed to the other end of the swing arm 805, and a second connecting rod 807 hinged between the swing arm 805 and the rotating sleeve 804. Among them, the rotating sleeve 804 is rotatably installed on the outer surface of the sliding sleeve 803. The number of the swing arm 805, the gravity ball 806 and the second connecting rod 807 in the centrifugal adjustment structure 8 is two, and the two swing arms 805 are symmetrically arranged. A return spring 808 is rotatably installed between the sliding sleeve 803 and the rotating shaft 801. A connecting frame 809 connected to the pushing structure 9 is fixed to the outer surface of the bottom end of the sliding sleeve 803. When the rotating shaft 801 rotates, due to the action of centrifugal force, the sliding sleeve 803 will generate a radial displacement relative to the rotating shaft 801, which is transmitted to other parts of the device through the connecting frame 809 and cooperates with the pushing structure 9 to realize the reciprocating adjustment of the sterilization cylinder 3, thereby realizing the adaptive adjustment of the operating state of the device.

[0057] In addition, the two symmetrically arranged swing arms 805 and gravity balls 806 will generate opposite radial forces under the action of centrifugal force, and these forces cancel each other out, which helps to maintain the overall stability of the device. The design of the return spring 808 enables the sliding sleeve 803 and the rotating sleeve 804 to quickly return to the initial position when the centrifugal force decreases or disappears, ensuring the quick response and stability of the device.

[0058] To achieve the adjustment of the sterilization cylinder 3 and the sterilization sleeve 4, the pushing structure 9 includes a sliding plate 901 slidably disposed inside the box body 101 and fixed to one side of the connecting frame 809. An inclined chute 902 is provided inside the sliding plate 901. A roller 903 is rotatably connected inside the chute 902. A shaft rod 904 is fixed to the inner side of the roller 903, and the other end of the shaft rod 904 is fixed with a docking seat 905 rotatably connected to the left hollow shaft 106. Specifically, the rolling connection mechanism between the roller 903 and the chute 902 reduces the direct contact and wear between components, extends the service life of the equipment, and the docking seat 905 where the shaft rod 904 fixed to the inner side of the roller 903 is rotatably connected to the left hollow shaft 106 ensures precise control during the movement of the pushing structure 9. And this rolling friction mechanism has smaller frictional resistance and higher movement smoothness compared with sliding friction, which helps to reduce vibration and noise during the operation of the equipment. A guiding member for guiding the sliding plate 901 is installed inside the box body 101 to enable it to move stably.

[0059] Among them, a transmission component is provided between the sliding plate 901 and the wire winding structure 10. The wire winding structure 10 includes two support seats 1001 fixed to the inner bottom wall of the box body 101. A support shaft 1002 is installed between the two support seats 1001 through bearings. A wire winding disc 1003 is detachably installed on the outer surface of the support shaft 1002. A pull rope 1004 connected to the sterilization sleeve 4 is wound around the wire winding disc 1003. Through the meshing action of the docking shaft 11, the second driven gear 12 and the rack 13, the transmission component realizes the power transmission and linkage between the sliding plate 901 and the wire winding structure 10. When the sliding plate 901 moves, the rack 13 drives the second driven gear 12 to rotate, and then drives the docking shaft 11 and the support shaft 1002 to rotate, realizing the automatic wire winding or wire unwinding of the wire winding disc 1003, enabling the equipment to automatically adjust the length of the pull rope 1004 according to the movement of the sliding plate 901, thereby realizing the automatic control of the position of the sterilization sleeve 4 without manual intervention, improving the automation degree and operation convenience of the equipment. Specifically, the transmission component includes a docking shaft 11 fixed to one end of the support shaft 1002. A second driven gear 12 is fixed to the other end of the docking shaft 11. A rack 13 meshing with the second driven gear 12 is fixed to the left side of the sliding plate 901. In addition, the pull rope 1004 is fixedly connected to the connection seat 16 at the bottom of the sterilization sleeve 4, realizing the coordinated operation with the wire winding structure 10. When the wire winding structure 10 winds or unwinds the wire, the pull rope 1004 will drive the sterilization sleeve 4 to move, thereby realizing the automatic control of the position of the sterilization sleeve 4. And the stable sterilization sleeve 4 and the automatic reset function reduce the failure rate of the equipment during operation. This helps to improve the reliability and stability of the equipment and extend the service life of the equipment.

[0060] To ensure the stable movement of the sterilization sleeve 4, connecting seats 16 are fixed on the upper and lower sides of the two mounting discs 2 and the upper and lower sides of the sterilization sleeve 4. The sterilization sleeve 4 is located between the two connecting seats 16, and a guide rod 17 passing through the interiors of the middle two connecting seats 16 is fixed between the left and right connecting seats 16. Among them, a tension spring 18 surrounding the outer portion of the bottom guide rod 17 is fixed between the connecting seat 16 at the bottom of the sterilization sleeve 4 and the connecting seat 16 at the bottom right. One end of the pull rope 1004 away from the wire reel 1003 is fixed to the outer surface of the connecting seat 16 at the bottom of the sterilization sleeve 4. Through the fixation of the connecting seats 16 and the guide rod 17, the sterilization sleeve 4 is stably supported between the two mounting discs 2, reducing shaking and deviation during the operation of the device. When the device stops running, the elastic force of the tension spring 18 will cause the sterilization sleeve 4 to automatically reset to the initial position. This automatic reset function ensures the continuous and stable operation of the device and reduces the need for manual intervention. A support rod (not shown in the figure) for supporting the sterilization cylinder 3 can also be rotatably installed inside the box body 101. A bushing is installed on the outer surface of the support rod, and the bushing is rotatably connected to the outer surface of the left end of the sterilization cylinder 3. The bushing is spline-connected to the support rod.

[0061] To improve the irradiation effect, mounting discs 2 are fixed on both the left and right sides of the hollow drum 103, and a guiding structure for rotating the sterilization cylinder 3 is provided inside the left mounting disc 2. The guiding structure includes an elastic guide rod 20 provided inside the left mounting disc 2 and a ball 21 rotatably installed at the bottom end of the elastic guide rod 20. An installation groove 19 for installing the elastic guide rod 20 is formed inside the left mounting disc 2, and the bottom side of the installation groove 19 communicates with the outside. A guiding groove 22 is formed inside the sterilization cylinder 3 and is arranged around the outer surface. The ball 21 is in rolling connection with the inner side of the guiding groove 22 and cooperates with the movement of the pushing structure 9 to cause the sterilization cylinder 3 to rotate automatically. Through the cooperation of the elastic guide rod 20, the ball 21, and the guiding groove 22, the sterilization cylinder 3 can rotate automatically during movement, which helps the towels to be evenly distributed inside the sterilization cylinder 3 and further improves the sterilization effect. The length of the guiding groove 22 is adapted to the displacement distance of the sterilization cylinder 3. A limiting platform for limiting the centrifugal adjustment structure 8 is fixed on the outer surface of the left mounting disc 2.

[0062] To achieve the cleaning of the hollow drum 103, a cleaning mechanism for cleaning the hollow drum 103 is provided inside the box body 101 at one end of the sterilization cylinder 3 away from the pushing structure 9. The cleaning mechanism includes a cleaning brush disk 5 detachably installed at the right end of the sterilization cylinder 3 and a piston structure 15 fixed to the inner bottom wall of the box body 101. A suction pipe 14 is fixed to the outer surface of the sterilization sleeve 4. The piston structure 15 includes a storage box 1501 fixed to the inner bottom wall of the box body 101, a valve pipe 1502 fixedly connected to the top side of the storage box 1501, and a plug pipe 1503 fixedly connected to one side of the valve pipe 1502. A piston block 1504 is reciprocally arranged inside the plug pipe 1503. Two check valves 1505 are elastically hinged inside the valve pipe 1502. One side of the piston block 1504 is fixed with a third connecting rod 1506 extending outside the plug pipe 1503. The other end of the third connecting rod 1506 is fixed to the outer surface of a connecting seat 16 at the bottom of the sterilization sleeve 4. The top side of the valve pipe 1502 is flange-connected with a suction pipe 1507 communicated with the suction pipe 14. Through the linkage of the piston structure 15 with the connecting seat 16 at the bottom of the sterilization sleeve 4 and the suction pipe 14, the automatic cleaning of the inner wall of the sterilization cylinder 3 is realized. When the sterilization sleeve 4 moves, the piston block 1504 reciprocates inside the plug pipe 1503, and the residues on the inner wall of the sterilization cylinder 3 are sucked into the storage box 1501 through the valve pipe 1502 and the suction pipe 1507. The automatic cleaning function reduces the need for manual intervention and improves the cleaning efficiency. The operator does not need to manually clean the inner wall of the sterilization cylinder 3 and can focus more on other operations of the equipment.

[0063] It should be noted that a maintenance door is detachably installed on the side wall of the box body 101 for the maintenance of functional modules and for the disassembly and assembly of the storage box 1501 to regularly discharge the impurities inside it. The displacement distance of the piston block 1504 is adapted to the moving distance of the sterilization sleeve 4. The cleaning brush disk 5 is of light weight.

[0064] As Figure 1 - Figure 9 shown, the principle of the rotary circulating air rapid towel drying box provided in this embodiment is as follows:

[0065] The driving motor 107 drives the hollow drum 103 to rotate through the gear member 111. The impeller 109 generates negative pressure to make the towel adhere to the outer surface of the hollow drum 103. The heating device 104 blows hot air, which penetrates the towel through the hollow holes;

[0066] When the hollow drum 103 rotates, it drives the centripetal adjustment structure 8 to work through the meshing of the transmission gear 6 and the first driven gear 7. The gravity ball 806 of the centripetal adjustment structure 8 expands outward due to the increased centrifugal force. At this time, the second connecting rod 807 pushes the sliding sleeve 803 to move upward, drives the sliding plate 901 to move upward through the connecting frame 809, and forces the roller 903 to push the sterilization cylinder 3 into the drum through the chute 902 of the sliding plate 901. At the same time, the rack 13 drives the wire reel 1003 to tighten the pull rope 1004, pulls the sterilization sleeve 4 to displace, and the sterilization cylinder 3 and the sterilization sleeve 4 move relative to each other;

[0067] When the sterilization cylinder 3 displaces, it drives the cleaning brush disc 5 to rotate by itself through the rolling of the ball 21 along the guide groove 22. The sterilization sleeve 4 is pulled by the pull rope 1004 to move horizontally, and the ultraviolet sterilization lamp 41 covers different areas;

[0068] After drying is completed, the sterilization cylinder 3 and the sterilization sleeve 4 return to their original states. The sterilization cylinder 3 exits the hollow drum 103, and the sterilization sleeve 4 displaces to the other side of the hollow drum 103. When the sterilization cylinder 3 and the sterilization sleeve 4 resume displacement, they will drive the cleaning brush disc 5 and the piston structure 15 respectively. When the sterilization sleeve 4 moves, it pulls the piston block 1504 to generate negative pressure through the third connecting rod 1506 to achieve dust collection and prevent the accumulation of lint and the growth of bacteria.

[0069] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of the components as the criterion for distinction. As mentioned throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.
