Description

Technical Field

[0001] This utility model relates to a dryer, and more particularly to a portable shoe dryer and sterilizer. Background Technology

[0002] A shoe dryer, also known as a shoe warmer or shoe dryer, is a small household appliance specifically designed for drying shoes. Some people's feet tend to sweat, which can make the inside of their shoes damp and prone to harboring various bacteria, affecting foot health. Therefore, shoe dryers were developed to conveniently dry and sterilize shoes.

[0003] However, existing shoe dryers typically only have one or two pairs of air outlet arms, meaning they can only dry one or two pairs of shoes at a time. If taken on outdoor activities such as camping or rafting where shoes and socks are likely to get wet, and there are many people, then one has to wait for the previous pair of shoes to dry, making it difficult to meet the needs of drying multiple shoes. On the other hand, existing shoe dryers that can dry multiple shoes have problems such as complex structure, susceptibility to bumps and knocks, and poor portability. Utility Model Content

The power module is used to connect to the mains power through a power plug 5. The upper ends of the four pairs of air outlet hoses 24 are respectively installed at the four edges of the lower side of the control box 1 for storage inside the storage box. Each air outlet hose 24 has an air outlet at its lower end for extending into the shoe. The head 26 has several air outlets 27; each air outlet hose 24 is equipped with an ultraviolet light strip 25; a hot air drying mechanism is installed on the storage box to deliver hot air to each air outlet hose 24; a second electric control switch connected in series with the controller is connected to the power supply line of each ultraviolet light strip 25; the hot air drying mechanism is controlled by the controller; a display screen 3 and a button panel 4 connected to the controller are installed on the top surface of the control box 1; a portable handle 2 is swaying on the top of the control box 1; a flexible sleeve 11 is provided on the portable handle 2.

[0024] Hot air is supplied to each air outlet hose 24 by the hot air drying mechanism, so that the hot air is blown out from the lower end of the air outlet hose 24 into the shoe to achieve hot air drying. The air outlet hose 24 can be inserted into different shoe types, such as high boots and sports shoes. Several air outlet holes 27 on the air outlet head 26 at the end of the air outlet hose 24 ensure that the hot air is blown out evenly.

The opening handle 37 is used to make it easy to open and close the storage cover 36. The avoidance slot is used to facilitate the routing of the power plug 5 and to prevent the storage cover 36 from pressing the cable.

[0027] Furthermore, the storage box includes a storage tube 9 and an air supply box 6; the lower opening of the storage tube 9 is fixed to the upper side of the air supply box 6; a telescopic outer tube 14 located inside the storage tube 9 is fixedly connected to the center of the upper side of the storage tube 9; a telescopic inner tube 10 is inserted into the upper end of the telescopic outer tube 14, and the upper end of the telescopic inner tube 10 is fixedly connected to the center of the lower side of the control box 1; each air outlet hose 24 is used to be stored inside the storage tube 9; a limiting groove 15 is vertically provided on the telescopic inner tube 10. A limiting block that slides along the limiting groove 15 is installed at the upper opening of the telescopic outer tube 14; an opening and closing spring 16 for driving the telescopic inner tube 10 to move upward is installed inside the telescopic outer tube 14; a positioning post 13 is fixed on one vertical side of the control box 1; a locking cap 31 is rotatably installed on one vertical side of the storage tube 9; a locking hook 12 is fixed on the locking cap 31; and a locking torsion spring for driving the locking hook 12 to snap onto the positioning post 13 is installed inside the locking cap 31.

[0028] The storage tube 9 is used to store the air outlet hose 24; the opening and closing spring 16 drives the telescopic inner tube 10 to move the control box 1 upward, opening the upper opening of the storage tube 9. At this time, the air outlet hose 24 can be taken out for use; put each air outlet hose 24 into the storage tube 9, rotate the locking cap 31 to swing the locking hook 12 to one side, press down the control box 1 to block the upper opening of the storage tube 9, release the locking cap 31 to reset under the drive of the locking torsion spring, and hook the locking hook 12 onto the positioning post 13 to achieve storage and locking.

[0029] Furthermore, the hot air drying mechanism includes a fan 18 and a heating box 19; both the fan 18 and the heating box 19 are installed inside the air supply box 6, and the fan is electrically connected to the controller via a fan drive circuit; a connecting hole 17 is provided at the center of the top plate of the air supply box 6; the air inlet of the fan 18 is connected to the heating box 19, and the air outlet of the fan 18 is connected to the connecting hole 17; an electric heating wire is installed inside the heating box 19; and an outer end extending to the air supply box 6 is fixedly connected to the heating box 19. The air inlet duct 20 is located on the side vertical outer wall; a first electric control switch connected in series with the controller is connected to the power supply line of the heating wire; an air collection duct connected to the upper end of the telescopic inner tube 10 is fixed inside the control box 1, and the upper end of the air collection duct is closed; two top-closed connecting pipes 32 are fixed through the four edges of the bottom of the control box 1; each connecting pipe 32 is connected to the air collection duct through a connecting pipe 34; the upper end of each air outlet hose 24 is respectively connected to the lower end of each connecting pipe 32.

[0030] The controller inside the heating box 19 is heated by an electric heating wire, and the airflow generated by the fan 18 blows out the hot air inside the heating box 19 to form hot air. The hot air enters the air outlet hose 24 through the connecting hole 17, the telescopic outer pipe 14, the telescopic inner pipe 10, the air collection pipe, each connecting pipe 34 and each connecting pipe 32 to realize the hot air delivery.

[0031] Furthermore, a temperature sensor 35 electrically connected to the controller is installed on the air collection duct; a buzzer electrically connected to the controller is installed on the control box 1.

[0032] The buzzer emits a prompt tone under the control of the controller, such as emitting multiple short prompt tones after the drying time is over. The temperature sensor 35 monitors the temperature at the air collection duct and presets a temperature threshold. When the detected temperature is higher than the temperature threshold, the controller controls the buzzer to emit a continuous prompt tone.

[0033] Furthermore, multiple counterweights 23 are fixed inside the heating box 19; multiple support legs 7 are provided at the bottom of the heating box 19; and an anti-slip layer 8 is provided on the lower side of each support leg 7. The counterweights 23 are used to improve the stability of the heating box 19 and reduce the impact of the weight of wet shoes on the drying and sterilizing device.

[0034] Furthermore, each connecting tube 32 is connected in series with a insertion tube 33; each vertical side of the control box 1 is provided with two insertion holes 28 corresponding to the positions of the two insertion tubes 33 on the corresponding side; each insertion hole 28 is inserted with a partition plate 29 extending into the corresponding insertion tube 33, the partition plate 29 is used to isolate the corresponding connecting tube 32; a pull-out flange 30 is vertically provided on the outer edge of the partition plate 29.

[0035] The partition plate 29 is inserted into the insertion tube 33, which isolates the connecting tube 32, preventing hot air from entering the corresponding air outlet hose 24. This allows the number of air outlet hoses 24 in use to be adjusted according to the number of shoes to be dried. The pull-out flange 30 facilitates the removal and removal of the partition plate 29.

[0036] Furthermore, a U-shaped socket is fixed to the heating box 19, surrounding the outer end of the air inlet duct 20; a filter screen 22 is inserted into the U-shaped socket 21 to cover the outer end of the air inlet duct 20. The filter screen 22 filters the air entering the air inlet duct 20, reducing dust and impurities that enter the shoes with the hot air; the insertion method of the filter screen 22 makes it easy to replace.
