The ultraviolet light source 21 at least partially protrudes from the surface of the housing 10; and / or a recessed area A is formed on the housing 10 at the location of the ultraviolet light source 21, and the ultraviolet light source 21 at least partially protrudes from the surface of the recessed area A.

[0050] The housing 10 is generally L-shaped and includes a main body 11 that can be inserted into the shoe body and an extension 14 that is bent from one end of the main body 11 . The ultraviolet light source 21 is disposed on the main body 11 .

[0051] The main body 11 is provided with a plurality of support members 12 protruding from the surface of the main body 11. The protruding height of the support members 12 is not less than the protruding height of the ultraviolet light source 21. The plurality of support members 12 are arranged around the circumference of the main body 11, so that when the main body 11 is inserted into the shoe, the support members 12 can maintain the distance between the inner surface of the shoe and the surface of the main body 11, so as to construct a sterilization space between the main body 11 and the inner surface of the shoe.

[0052] The support member 12 includes a first support member 121 and a second support member 122. The first support member 121 is disposed on the lower surface of the main body 11 (after the main body 11 is inserted into the shoe, the surface corresponding to the bottom of the shoe is the lower surface). There are multiple first support members 121, which are arranged in at least two rows, so that when the main body 11 is inserted into the shoe, the stability between the main body 11 and the bottom of the shoe can be maintained. There are multiple second support members 122, which are disposed on the side surface and the upper surface of the main body 11.

[0053] Preferably, each support member 12 is configured as a sheet structure and is arranged parallel to the axis of the main body 11. Each support member 12 is arranged with chamfers at the front and rear of the main body 11 in the axial direction.

[0054] refer to Figure 3As shown, a first gas flow channel 111 is formed in the main body 11, and the first gas flow channel 111 extends and distributes in the axial direction of the main body 11. A gas outlet 112 connected to the first gas flow channel 111 is provided on the main body 11. Preferably, the gas outlet 112 is provided on a side end surface of the main body 11 away from the extension portion 14. The shape of the gas outlet 112 can be a strip or a circle or other shapes, preferably a strip. The number of the gas outlet 112 can be multiple.

[0055] refer to Figure 1 and Figure 4 As shown, a plurality of light emitting hole groups 13 are arranged along the first direction on the main body 11, each light emitting hole group 13 includes a plurality of light emitting holes 131 arranged along the second direction, and each light emitting hole 131 is arranged through the main body 11 in the thickness direction. The light emitting hole 131 is used for the ultraviolet light source 21 in the sterilization component to pass through.

[0056] In one embodiment, the first direction is the axial direction of the main body 11, and the second direction is the circumferential direction of the main body 11. That is, a plurality of light exit holes 131 are arranged in a ring around the surface of the main body 11 to form a group of light exit holes 13; a plurality of groups of light exit holes 13 are arranged on the surface of the main body 11 along the axial direction of the main body 11. In this embodiment, the support member 12 is arranged between two adjacent light exit holes 131 of the same group of light exit holes 13.

[0057] In another embodiment, the first direction is the circumferential direction of the main body 11, and the second direction is the axial direction of the main body 11. That is, a plurality of light exit holes 131 are arranged in a strip shape on the surface of the main body 11 along the axial direction of the main body 11 to form a group of light exit holes 13; a plurality of groups of light exit holes 13 are arranged around the surface of the main body 11. In this embodiment, the support member 12 is arranged between two adjacent groups of light exit holes 13.

[0058] In other embodiments, the light exit holes 131 may also be freely distributed on the main body 11 in other regular or irregular patterns.

[0059] refer to Figure 1 and Figure 2 As shown, a recessed area A is formed on the surface of the main body 11 at each light exit hole 131, and the light exit hole 131 is located in the middle area of ​​the corresponding recessed area A. By setting the recessed area A, the light exit angle of the ultraviolet light source 21 can be further expanded, and the shielding of the ultraviolet light source 21 by the main body 11 can be reduced. At the same time, the ultraviolet light source 21 is sunken in the recessed area A, which can reduce bumps and extend the service life.

[0060] The main body 11 is provided with a reflective coating on the surface of the recessed area A. The reflective coating includes an aluminum coating and / or a Teflon coating.

[0061] refer to Figure 3As shown, in order to maximize the sterilization performance of the ultraviolet light source 21, there is a distance D between two adjacent light exit holes 131 in each light exit hole group 13. The support member 12 has a preset height H protruding from the surface of the main body 11; the ratio of the preset height H to the distance D ranges from 0.5 to 5.

[0062] refer to Figure 3 , Figure 4 and Figure 5 As shown, in order to facilitate the fixation of the ultraviolet light source 21 and to easily construct the air flow channel located at the ultraviolet light source 21, a strip or annular accommodating groove 14 is provided on the inner wall of the main body 11, and a plurality of accommodating grooves 14 are also arranged along the first direction or the second direction, and each accommodating groove 14 corresponds to a group of light emitting hole groups 13, and the light emitting holes 131 in each group of light emitting hole groups 13 are all located in the corresponding accommodating grooves 14.

[0063] The ultraviolet light source 21 is preferably an ultraviolet LED lamp or a light strip with ultraviolet LED lamps. The ultraviolet LED lamp or ultraviolet LED light strip is disposed in the receiving groove 14, and the ultraviolet LED lamp thereon protrudes from the surface of the main body 11 and / or the surface of the recessed area A through the light outlet hole 131.

[0064] In one embodiment, reference Figure 5 As shown, a gap is formed between the UV LED lamp or UV LED light strip and the inner wall of the receiving groove 14 and the inner wall of the light outlet hole 131. When the gas flows inside the housing 10, the gap can form a gas flow channel, so that the gas in the housing 10 flows out from the gap, taking away the heat emitted by the UV light source 21, achieving cooling and extending the service life. At the same time, the heat taken away by the gas can act on the inside of the shoes to improve the dehumidification and mildew prevention effect.

[0065] In another embodiment, an air hole (not shown) is provided on the main body 11 in the area where the accommodating groove 14 is located. Preferably, the air hole is arranged in the recessed area A. The ultraviolet light source 21 partially covers or does not cover the air hole arrangement. In this embodiment, the air hole can also form a gas flow channel when the gas circulates inside the shell 10. When the ultraviolet light source 21 partially covers the air hole arrangement, when the gas in the shell 10 flows out from the air hole, it can also take away the heat emitted by the ultraviolet light source 21, thereby achieving cooling and extending the service life. At the same time, the heat taken away by the gas can act on the inside of the shoe to improve the dehumidification and mildew-proofing effect.

[0066] refer to Figure 2 and Figure 5 As shown, the sterilization assembly further includes a lens 22, and the lens 22 covers the ultraviolet light source 21. The arrangement of the lens 22 expands the light output angle of the ultraviolet light source 21 and improves the sterilization efficiency.

[0067] refer to Figure 1 and Figure 3 As shown, a second gas flow channel 141 communicating with the first gas flow channel 111 is formed in the extension portion 14, and an air inlet 142 communicating with the second gas flow channel 141 is provided on the extension portion 14. Preferably, the air inlet 142 is provided on a side end surface of the extension portion 14 away from the main body portion 11. The air inlet 142 may be in the shape of a strip, and may be in multiple numbers, and the multiple air inlets 142 are arranged in a ring shape on the edge of the end surface of the extension portion 14.

[0068] In order to facilitate the taking of the shoe sterilization device and at the same time ensure that the end of the extension part 14 close to the main part 11 does not block the air outlet of the shoe opening, thereby affecting the air outlet of the shoe opening, the inner diameter of the extension part 14 gradually increases in the direction away from the main part 11, and the overall setting is an inverted cone; or, the inner diameter of the extension part 14 remains unchanged and then increases in the direction away from the main part 11, and the overall axial cross-section is roughly T-shaped; or, the inner diameter of the extension part 14 first decreases and then increases in the direction away from the main part 11, and the overall setting is an hourglass shape.

[0069] In order to increase the airflow circulation speed and circulation strength inside the housing 10, a fan 30 is further provided inside the housing 10. The fan 30 is provided inside the first airflow channel 111 or the second airflow channel 141, and the fan 30 is configured to rotate to generate airflow inside the first airflow channel 111 and the second airflow channel 141. In this embodiment, the provision of the support member 12 on the surface of the housing 10 also constructs a ventilation channel between the housing 10 and the inner surface of the shoe, so that the gas discharged from the air outlet 121 of the housing 10 can be discharged into the shoe along the ventilation channel, thereby improving the ventilation efficiency inside the shoe and improving the sterilization efficiency.

[0070] The shoe sterilization device further includes a sensor 40 disposed on the upper surface of the main body 11. The sensor 40 is located behind the second support member 122 in the insertion direction of the main body 11 (i.e., the side close to the extension portion 14 is the rear side) and is electrically connected to the sterilization component. Preferably, the sensor 40 has the same shape and size as the second support member 122. The sensor 40 has a light sensing function and a force sensing function; the sensor 40 is configured such that when the light sensing function and the force sensing function of the sensor 40 are triggered simultaneously, the ultraviolet light source 21 of the sterilization component is illuminated.

[0071] It is understandable that, looking from the direction of the shoe sterilization device being placed or inserted into the shoe, that is, after the shoe sterilization device is placed into the shoe, the top of the inner surface of the shoe will squeeze the sensor 40 and block the sensor 40, thereby triggering the light sensing function and the force sensing function of the sensor 40 at the same time, and then triggering the ultraviolet light source 21. As long as any one of the two functions of the sensor 40 is not triggered, the ultraviolet light source 21 cannot be lit, which can ensure the safety of the user.

[0072] A power source (not shown) for supplying power to the sterilization component is also provided in the housing 10. A control unit for controlling the sensor 40, the fan 30, the sterilization component and the power source is also provided on the housing 10. The control unit also includes an operation panel 51 and a button 52 provided on the housing 10. Preferably, the operation panel 51 and the button 52 are provided on the end surface of the extension portion 14 away from the main body 11.

[0073] Compared with the prior art, the shoe sterilization device of the present invention constructs a sterilization space between the shell and the inner surface of the shoe through the setting of the support, maintains the distance between the inner surface of the shoe and the ultraviolet light source, and avoids the ultraviolet light source being covered by the shoe. At the same time, through the protruding setting of the ultraviolet light source, the ultraviolet light source is prevented from being blocked by the shell, resulting in a limited irradiation range, thereby improving the sterilization efficiency.

[0074] The shoe sterilization device of the present invention increases ventilation ducts between the shell and the inner surface of the shoe by arranging the supporting member, thereby improving ventilation efficiency in the shoe and improving sterilization efficiency.

[0075] The shoe sterilization device of the present invention expands the light output angle of the ultraviolet light source and improves the sterilization efficiency by arranging a lens on the ultraviolet light source.

[0076] The shoe sterilization device of the present invention can ensure the safety of users by providing a sensor with light sensing function and force sensing function, and setting the sensor to light up the ultraviolet light source after the light sensing function and the force sensing function are triggered simultaneously.

[0077] The shoe sterilization device of the present invention can form a gas flow channel by setting air holes or gaps where the ultraviolet light source is located, so as to take away the heat emitted by the ultraviolet light source, achieve cooling, and extend the service life. At the same time, the heat taken away can act on the inside of the shoe to improve the dehumidification and mildew-proofing effect.

[0078] The shoe sterilization device of the present invention can further expand the light output angle and reduce obstruction by setting a recessed area on the shell surface where the ultraviolet light source is located. The ultraviolet light source is sunken in the recessed area to reduce bumps and extend the service life.
