[0043] In the field of dryer technology, some dryers use steam sterilization technology, but this type of sterilization technology can cause significant damage to thin and delicate clothing; some dryers use silver ion sterilization technology, but silver ions are heavy metal ions, which can easily raise concerns about their safety; and some dryers use ultraviolet light to directly irradiate the inside of the drying drum for sterilization, but long-term exposure to ultraviolet light can easily damage clothing.

[0044] Based on this, the following embodiments are proposed:

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment provides a sterilization component, including:

[0047] The housing 1 forms a cavity 101, and the housing 1 is provided with an air inlet and an air outlet communicating with the cavity 101. The inner sidewall of the housing 1 is coated with a photocatalyst layer.

[0048] Light source 2 is disposed in the cavity 101 of the housing 1. The light energy provided by the light source 2 excites the photocatalyst layer to carry out a photocatalytic reaction to generate bactericidal substances. The airflow enters the cavity 101 through the air inlet and carries the bactericidal substances out through the air outlet.

[0049] In this embodiment, the sterilization component includes a housing 1 and a light source 2. A cavity 101 is formed inside the housing 1, and an air inlet 102 and an air outlet are provided on the side wall of the housing 1. The cavity 101, air inlet 102, and air outlet are interconnected to form an air duct. A photocatalyst layer is coated on the inner side wall of the housing 1. This photocatalyst layer can react with a specific light source 2 to produce an active substance with bactericidal properties. The light source 2 can be disposed on the inner side wall of the housing 1 or at other locations within the cavity 101 of the housing 1. The mounting position of the light source 2 on the housing 1 is sufficient to ensure that the light source 2 directly irradiates only the photocatalyst layer on the inner side wall of the housing 1. The light waves emitted by the light source 2 can generate a photocatalytic reaction with the photocatalyst layer, exciting the photocatalyst layer to produce an active substance with bactericidal properties. This active substance can diffuse along the direction of airflow.

[0050] When the sterilization component is applied to the garment processing equipment, the airflow in the air duct first flows into the cavity 101 of the housing 1 from the air inlet 401, and mixes with the active substance with sterilization effect generated by the light source 2 and the photocatalyst layer in the cavity 101. The active substance with sterilization effect is then pushed out from the air outlet with the airflow and moves into the interior of the garment processing equipment, thereby entering the garment processing drum to sterilize and disinfect the garments to be processed.

[0051] The sterilization method of this sterilization component can prevent the light waves from directly irradiating the clothes inside the drum. In this structure, after the airflow enters the cavity 101 of the housing 1 through the air inlet 102, it sterilizes the airflow entering the cavity 101. At the same time, the active substances with sterilization effect in the cavity 101 are discharged from the air outlet along with the sterilized airflow and enter the clothes treatment drum to sterilize the clothes. Thus, it can sterilize the clothes while avoiding damage caused by direct irradiation of the clothes by the light source.

[0052] Preferably, the side of the housing 1 closest to the air outlet can be a sidewall with a number of through holes evenly distributed. Alternatively, the housing 1 can be a groove-shaped metal part, in which case the side of the housing 1 closest to the air outlet is a groove without a sidewall.

[0053] Preferably, the selection of the light source 2 needs to match the photocatalyst layer. Different photocatalyst layers and their corresponding light sources 2 can be selected according to actual needs.

[0054] By coating a photocatalyst layer on the inner wall of the housing 1 with cavity 101, and placing a light source 2 corresponding to the photocatalyst layer in the cavity 101 of the housing 1, the airflow entering the cavity 101 can mix with the bactericidal active substance, and push the bactericidal active substance to be discharged from the air outlet with the airflow and move into the interior of the clothing treatment equipment, thereby entering the clothing treatment drum to sterilize the clothes to be treated.

[0055] Optionally, such as Figure 1 As shown, in one implementation of this embodiment,

[0056] The housing 1 includes an annular peripheral sidewall 103 and a front wall 104 disposed at one end of the annular peripheral sidewall 103;

[0057] The air inlet includes a plurality of air inlet holes 102 formed on the front wall 104;

[0058] And / or, the air inlet includes a plurality of air inlet holes 102 formed on at least one wall surface of the annular circumferential sidewall 103.

[0059] In this embodiment, the housing 1 includes a peripheral sidewall 103, a front wall 104, and a rear wall 105. The front wall 104 is disposed on one side of the peripheral sidewall 103, and the rear wall 105 is disposed opposite to the front wall 104 on the other side of the peripheral sidewall 103. The air inlets 102 on the housing 1 can be arranged in various ways, such as having multiple air inlets 102 evenly distributed on the front wall 104, multiple air inlets 401 evenly distributed on at least one wall surface of the peripheral sidewall 103, or multiple air inlets 102 simultaneously and evenly distributed on at least one wall surface of the front wall 104 and the peripheral sidewall 103. The air outlet is formed on the rear wall 105, meaning that the air outlet can be disposed opposite to the front wall 104, allowing airflow to enter through the air inlets 102, flow through the cavity 101 of the housing 1, and finally exit from the air outlet.

[0060] Preferably, in order to increase the coating area of ​​the photocatalyst layer and further enhance the bactericidal effect of the active substance with bactericidal effect, the multiple air inlets 102 are opened on at most two side walls of the housing 1, while the other walls of the housing 1 are not opened with air inlets 102. When the multiple air inlets 102 are opened only on the front wall 104 or at least one of the peripheral side walls 103, or when the multiple air inlets 102 are opened on at least one of the front wall 104 and the peripheral side walls 103, the aperture of the air inlets 102 can be adjusted according to the air duct power requirements of the clothing processing equipment, thereby maximizing the utilization of the cavity 101 space of the housing 1.

[0061] By limiting the number of air inlets 102 to a maximum of two side walls of the housing 1, and adjusting the aperture of the air inlets 102 according to the power requirements of the air duct of the garment processing equipment, the coating area of ​​the photocatalyst layer can be increased, maximizing the utilization of the cavity 101 space of the housing 1, thereby further enhancing the bactericidal effect of the active substances with bactericidal properties.

[0062] Optionally, such as Figure 1 and 3 As shown, in one implementation of this embodiment,

[0063] The annular circumferential sidewall 103 has a lower wall 1032, and a plurality of air inlets 102 are provided on the lower wall 1032;

[0064] The annular circumferential sidewall 103 is provided with a rear wall 105 at one end away from the front wall 104, and the air outlet is formed on the rear wall 105. The front wall 104 and the rear wall 105 are arranged parallel to each other.

[0065] And / or, the angle between the lower wall 1032 and the rear wall 105 is θ, where 10°≤θ≤60°.

[0066] In this embodiment, the peripheral sidewall 103 of the housing 1 has four parts: an upper wall 1031, a lower wall 1032, a left wall 1033, and a right wall 1034. When multiple air inlets 102 are provided on the front wall 104, multiple air inlets 102 are also provided on the lower wall 1032 of the peripheral sidewall 103. In this embodiment, to avoid convection effects when airflow enters from the air inlet 401 and to increase the airflow volume of the duct, air inlets 102 are provided on one wall surface of both the front wall 104 and the peripheral sidewall 103. Since the front wall 104 and the air inlet 401 are positioned opposite each other, providing the air inlet 401 on the front wall 104 improves the airflow efficiency of the duct. Since the upper space of garment processing equipment is often quite cramped, while the middle space is relatively spacious, and the lower wall 1032 of the peripheral sidewall 103 is roughly located in the middle of the garment processing equipment, the airflow from the lower wall 1032 of the peripheral sidewall 103 into the cavity 101 is more unobstructed, and the air intake volume is also larger. Therefore, multiple air inlets 102 are formed on the lower wall 1032 of the peripheral sidewall 103. The above structure can increase the air intake volume of the air duct and the air output volume of the air outlet, thereby allowing the active substances with bactericidal effect to diffuse more fully within the garment processing equipment, further improving the bactericidal effect on the garments to be treated.

[0067] By simultaneously opening air inlets 102 on the lower wall 1032 of the front wall 104 and the peripheral side wall 103, the airflow flowing into the housing 1 from both directions will not collide within the cavity 101. This avoids the convection effect when the airflow flows in from the air inlet 401. At the same time, the simultaneous air intake on both side walls of the housing 1 increases both the air intake volume of the air duct and the air output volume of the air outlet, thereby allowing the active substances with bactericidal effect to diffuse more fully within the clothing treatment equipment, further improving the sterilization efficiency of the clothing to be treated.

[0068] The front wall 104 and the rear wall 105 of the sterilization component are parallel, which minimizes the distance between the front wall 104 and the rear wall 105 of the sterilization component, thereby reducing the space occupied by the sterilization component.

[0069] The angle between the lower wall 1032 and the rear wall 105 is θ, where 10°≤θ≤60°. This forms a guide slope on the contact surface between the lower wall 1032 and the airflow. When the airflow contacts the lower wall 1032 and enters the cavity 101 of the housing 1 through the air inlet 102, the resistance it encounters is greatly reduced. Therefore, the airflow velocity when passing through the air inlet 102 is faster, resulting in a larger airflow rate through the cavity 101 of the housing 1 per unit time, which further improves the air intake volume of the air duct.

[0070] Optionally, such as Figure 1 , 2 As shown in Figure 4, in one implementation of this embodiment,

[0071] The photocatalyst layer is a titanium dioxide coating, and the light source 2 is an ultraviolet lamp.

[0072] In this embodiment, a titanium dioxide coating is selected as the photocatalyst, and correspondingly, an ultraviolet lamp is selected as the light source 2. The ultraviolet lamp itself has a sterilizing effect on the airflow, and it can undergo a photocatalytic reaction with the titanium dioxide coating. During the reaction, active substances with bactericidal effects, such as hydroxyl radicals and superoxide anions, are generated. These active substances are discharged from the air outlet and flow into the garment treatment drum through the air duct, thereby sterilizing the garments to be treated. Both the ultraviolet lamp and the titanium dioxide coating have a long history of application; their photocatalytic reaction technology is mature and cost-effective. The combination of the ultraviolet lamp and the titanium dioxide coating enables the ultraviolet light waves to combine with the active substances with bactericidal effects, such as hydroxyl radicals and superoxide anions, to achieve multiple sterilization functions.

[0073] By selecting titanium dioxide coating as a photocatalyst and ultraviolet lamp as the light source 2, the sterilization component can achieve multiple sterilization functions with the cooperation of ultraviolet lamp and titanium dioxide coating, so that bacteria and viruses in the clothing treatment drum can be killed more efficiently and comprehensively, thereby further improving the sterilization efficiency of the sterilization component.

[0074] Optionally, such as Figure 1 , 2 As shown in Figure 4, in one implementation of this embodiment,

[0075] The light source 2 has multiple light-emitting surfaces, and each of the multiple light-emitting surfaces corresponds to one of the inner sidewalls of the housing 1 coated with the photocatalyst layer.

[0076] In this embodiment, taking the light source 2 as an ultraviolet lamp, specifically an ultraviolet lamp column, as an example, since direct ultraviolet radiation on clothing can cause damage, the emitting surface of the ultraviolet lamp column is placed inside the cavity 101 of the housing 1. Furthermore, the ultraviolet lamp column can only directly irradiate the inner wall of the housing 1 coated with a photocatalyst layer, preventing direct ultraviolet light waves from irradiating the clothing inside the drum. With this structure, after the airflow enters the cavity 101 of the housing 1 through the air inlet 102, it is irradiated by ultraviolet radiation, sterilizing the airflow entering the cavity 101. Simultaneously, the hydroxyl radicals and superoxide anions generated by the ultraviolet lamp and the titanium dioxide coating inside the cavity 101, which have bactericidal effects, are discharged from the air outlet along with the sterilized airflow and enter the clothing treatment drum to sterilize the clothing. This achieves both sterilization and avoids damage caused by direct ultraviolet radiation.

[0077] By placing the light-emitting surface of the ultraviolet lamp column inside the cavity 101 of the housing 1, and ensuring that the ultraviolet lamp column can only directly irradiate the inner wall of the housing 1 coated with a photocatalyst layer, the sterilization component can sterilize the clothes while avoiding damage caused by direct irradiation of the clothes by ultraviolet rays.

[0078] Optionally, in one implementation of this embodiment, such as Figure 1 and 2 As shown,

[0079] The annular circumferential sidewall 103 has an upper wall 1031, a lower wall 1032, a left wall 1033, and a right wall 1034;

[0080] The photocatalyst layer is coated on the inner side of the front wall 104, the inner side of the upper wall 1031, the inner side of the lower wall 1032, and the inner side of the right wall 1034.

[0081] The light source 2 is mounted on the left wall 1033;

[0082] The plurality of light-emitting surfaces include a first light-emitting surface 201, a second light-emitting surface 202, a third light-emitting surface 203, and a fourth light-emitting surface 204;

[0083] The first luminescent surface 201 is opposite to the inner side of the upper wall 1031; the second luminescent surface 202 is opposite to the inner side of the lower wall 1032; the third luminescent surface 203 is opposite to the inner side of the front wall 104; and the fourth luminescent surface 204 is opposite to the inner side of the right wall 1034.

[0084] In this embodiment, a titanium dioxide coating is selected as the photocatalyst, and correspondingly, an ultraviolet lamp column is selected as the light source 2. The ultraviolet lamp column can undergo a photocatalytic reaction with the titanium dioxide coating, generating active substances with bactericidal effects such as hydroxyl radicals and superoxide anions during the reaction. The ultraviolet lamp column has four light-emitting surfaces, namely a first light-emitting surface 201, a second light-emitting surface 202, a third light-emitting surface 203, and a fourth light-emitting surface 204. The first luminescent surface 201 is opposite to the upper inner wall of the housing 1, that is, the inner wall of the upper wall 1031, and can illuminate the titanium dioxide coating coated on the inner wall of the upper wall 1031; the second luminescent surface 202 is opposite to the lower inner wall of the housing 1, that is, the inner wall of the lower wall 1032, and can illuminate the titanium dioxide coating coated on the inner wall of the lower wall 1032; the third luminescent surface 203 is opposite to the front inner wall of the housing 1, that is, the inner wall of the front wall 104, and can illuminate the titanium dioxide coating coated on the inner wall of the front wall 104; the fourth luminescent surface 204 is opposite to the right inner wall of the housing 1, that is, the inner wall of the right wall 1034, and can illuminate the titanium dioxide coating coated on the inner wall of the right wall 1034. Since the ultraviolet lamp column is installed inside the cavity 101 of the housing 1, at least one side of the ultraviolet lamp column must face the air inlet 401 that does not need ultraviolet irradiation. Therefore, this side is set as an opaque wall surface so that the ultraviolet light waves can be dispersed through all four light-emitting surfaces, thereby reducing the loss of ultraviolet light waves and reducing the energy consumption of the sterilization component.

[0085] By setting the four light-emitting surfaces of the ultraviolet lamp column opposite to the inner wall of the housing 1 coated with titanium dioxide, and setting the wall facing the air inlet 401 which does not require ultraviolet irradiation to be opaque, the ultraviolet light waves can be completely dispersed through the four light-emitting surfaces, thereby reducing the loss of ultraviolet light waves and reducing the energy consumption of the sterilization component.

[0086] Simultaneously, an assembly hole 1035 is provided on the left wall 1033 of the side wall 103 of the housing 1. The left wall 1033 is the assembly surface for the light source 2. The photocatalyst layer is not coated on the left wall 1033 to avoid ineffective coating.

[0087] Optionally, in one implementation of this embodiment, such as Figure 1 and 2 As shown,

[0088] An assembly hole 1035 is provided on the left wall 1033;

[0089] The sterilization component also includes a perforated fitting 3, which is installed in the mounting hole 1035;

[0090] The light source 2 includes a light source body 205 and a light source power cord 206. The light source body 205 is fixedly installed on the assembly 3. One end of the light source power cord 206 is electrically connected to the light source body 205, and the other end passes through the cavity 101 through the through hole of the assembly 3.

[0091] In this embodiment, an assembly hole 1035 is provided on the left wall 1033 of the periphery wall 103 of the housing 1. An assembly 3 is provided in the assembly hole 1035. The assembly 3 is made of a flexible and deformable material, and the outer diameter of the assembly 3 is slightly larger than the inner diameter of the assembly hole 1035, so that the assembly 3 can be installed in the assembly hole 1035 by interference fit. The assembly 3 has a through hole, and the relevant components of the ultraviolet lamp can cooperate with the assembly 3 through the through hole, so that the assembly 3 can fix or limit the relevant components of the ultraviolet lamp. At this time, the ultraviolet lamp can be suspended in the cavity 101 of the housing 1. The flexible assembly 3 can prevent the ultraviolet lamp from generating noise or falling off due to displacement relative to the housing 1. The ultraviolet lamp has a light source body 205 and a light source power cord 206. The light source power cord 206 is electrically connected to the light source body 205. The light source body 205 enters the cavity 101 of the housing 1 from the outside through a perforation and is fixed at the perforation of the fitting 3. The light source power cord 206 connected to the light source body 205 exits from the perforation of the fitting 3 and extends out of the cavity 101. When the sterilization component is working, the light source body 205 is powered on. At this time, the first light-emitting surface 201, the second light-emitting surface 202, the third light-emitting surface 203, and the fourth light-emitting surface 204 all start to emit light simultaneously. Ultraviolet light waves directly irradiate the inner wall of the housing 1 from the perforation of the fitting 3, thereby ensuring that the ultraviolet light waves can only directly irradiate the inner wall of the housing 1 coated with a photocatalyst layer.

[0092] The ultraviolet lamp is fixed to the left wall 1033 of the peripheral side wall 103 of the housing 1 by the fitting 3 which is interference-fitted with the mounting hole 1035. The ultraviolet lamp is simultaneously irradiated onto the inner side wall of the housing 1 through the four light-emitting surfaces. This ensures that ultraviolet light waves are prevented from leaking out of the mounting hole 1035, and prevents the ultraviolet lamp from generating noise or falling off due to displacement relative to the housing 1. The ultraviolet light waves can only directly irradiate the inner side wall of the housing 1 coated with the photocatalyst layer, further reducing the risk of ultraviolet light waves coming into direct contact with clothing.

[0093] In summary, the ingenious design of the sterilization component in this application lies in:

[0094] First, by coating a photocatalyst layer on the inner wall of a cavity-shaped housing and placing a light source corresponding to the photocatalyst layer within the cavity, the airflow entering the cavity mixes with a bactericidal active substance. This bactericidal active substance is then propelled by the airflow from the outlet and moves into the garment processing device, where it enters the garment processing drum for sterilization. This sterilization method avoids direct light waves from the light source onto the garments inside the drum, thus preventing damage caused by direct light irradiation.

[0095] Secondly, by limiting the number of air inlets to a maximum of two side walls of the housing and adjusting the aperture of the air inlets according to the power requirements of the air duct of the garment processing equipment, the coating area of ​​the photocatalyst layer can be increased, maximizing the utilization of the cavity space of the housing, thereby further enhancing the bactericidal effect of the active substances with bactericidal properties.

[0096] Third, by simultaneously opening air inlets on the lower walls of the front and peripheral side walls, the airflow flowing into the housing from two directions will not collide within the cavity, thus avoiding the convection effect when the airflow flows in from the air inlets. At the same time, the simultaneous air intake on both side walls of the housing increases both the air intake volume of the air duct and the air output volume of the air outlet, thereby allowing the active substances with bactericidal effects to diffuse more fully within the clothing treatment equipment, further improving the sterilization efficiency of the clothing to be treated.

[0097] Fourth, by selecting titanium dioxide coating as a photocatalyst and ultraviolet lamp as a light source, the sterilization component can achieve multiple sterilization functions with the cooperation of ultraviolet lamp and titanium dioxide coating, so that bacteria and viruses in the clothing treatment drum can be killed more efficiently and comprehensively, thereby further improving the sterilization efficiency of the sterilization component.

[0098] Fifth, by ensuring that all four emitting surfaces of the ultraviolet lamp column are far away from the air inlet on the panel, the ultraviolet light emitted by the ultraviolet lamp column can only irradiate the titanium dioxide coating inside the shell, thereby preventing the ultraviolet light from directly irradiating into the clothing treatment drum and protecting the clothes from damage caused by direct ultraviolet light.

[0099] Sixth, by installing the sterilization component at the air inlet and connecting the air outlet of the sterilization component to the air inlet, the cavity of the housing is connected to the air duct of the garment processing equipment. This allows the active substances with sterilization effect in the cavity to move with the airflow into the garment processing drum within the air duct of the garment processing equipment. As a result, the sterilization component not only sterilizes the clothes in the drum but also sterilizes the interior of the air duct, thereby further enhancing the sterilization effect of the sterilization component.

[0100] Seventh, the front and rear walls of the sterilization component are set to be parallel, and the angle between the lower wall and the rear wall of the sterilization component is set to be between 10° and 60°. This reduces the space occupied by the sterilization component and further increases the air intake of the air duct.

[0101] Example 2

[0102] like Figure 3 and 6 As shown, this embodiment provides a backplate, including:

[0103] Plate 4, with an air inlet 401 provided on it;

[0104] As in Embodiment 1, the sterilization component is installed at the air inlet 401 and the air outlet of the sterilization component is connected to the air inlet 401.

[0105] In this embodiment, the back panel includes a panel 4 and the sterilization component from Embodiment 1. An air inlet 401 is provided on the panel 4 to supply air to the air duct and the garment processing drum. The sterilization component from Embodiment 1 is installed at the air inlet 401, with its outlet connected to the inlet 401. When the sterilization component operates, the airflow in the air duct flows into the cavity 101 of the housing 1, mixing with the bactericidal active substance generated by the light source 2 and the photocatalyst layer within the cavity 101. This active substance is then propelled by the airflow from the cavity 101 to the air inlet 401 of the panel 4, allowing it to move within the air duct of the garment processing equipment and finally enter the garment processing drum for sterilization and disinfection. Since this embodiment includes the sterilization component from Embodiment 1, the back panel in this embodiment also possesses all the technical effects of the sterilization component from Embodiment 1, which will not be elaborated upon here.

[0106] Preferably, in the ultraviolet lamp column of the sterilization component, the first emitting surface 201 and the second emitting surface 202, which are arranged opposite to each other, can be arranged perpendicular to the plate 4, or they can form a certain angle with the plate 4 along the vertical direction of the plate 4. The third emitting surface 203 can be arranged parallel to the plate 4, or it can form a certain angle with the plate 4 along the horizontal direction of the plate 4. The fourth emitting surface 204 can be arranged perpendicular to the plate 4, or it can form a certain angle with the plate 4 along the horizontal direction of the plate 4. In the above structure, all four emitting surfaces of the ultraviolet lamp column are far away from the air inlet 401 on the plate 4. This allows the ultraviolet light waves emitted by the ultraviolet lamp column to only irradiate the titanium dioxide coating inside the housing 1, thereby preventing the ultraviolet light waves from directly irradiating into the clothing treatment drum and protecting the clothing from damage caused by direct ultraviolet light waves.

[0107] Preferably, in order to increase the drying air volume in the air duct, at least two air inlets 401 are provided on the plate 4, one of which is located at the top of the plate 4. Multiple mounting holes are provided around the top air inlet 401, and the mounting holes are evenly distributed on the plate 4 to fix and cooperate with the sterilization component, thereby strengthening the connection between the sterilization component and the plate 4.

[0108] By installing the sterilization component at the air inlet 401 and connecting the air outlet of the sterilization component to the air inlet 401, the cavity 101 of the housing 1 is connected to the air duct of the garment processing equipment. This allows the active substance with sterilization effect in the cavity 101 to move with the airflow into the garment processing drum within the air duct of the garment processing equipment. As a result, the sterilization component not only sterilizes the garments inside the drum but also sterilizes the interior of the air duct, thereby further enhancing the sterilization effect of the sterilization component.

[0109] Optionally, in one implementation of this embodiment, such as Figure 4 and 5 As shown,

[0110] The plate 4 has a wire hole 402, and a perforated sealing element 5 is sealed inside the wire hole 402. The sealing element 5 is constructed to be flexible. The light source power line 206 of the light source 2 passes through the perforation of the sealing element 5 and is electrically connected to the power source. The light source power line 206 and the perforation of the sealing element 5 are sealed together.

[0111] In this embodiment, a threading hole 402 is also provided on the plate 4, and a sealing member 5 is provided in the threading hole 402. The sealing member 5 has a perforation and is sealed to the threading hole 402. The sealing member 5 is made of a flexible and deformable material. The power supply line 206 of the light source 2 passes through the perforation of the sealing member 5 and is electrically connected to the power source. The power supply line 206 is sealed to the perforation of the sealing member 5. The flexible sealing member 5 can prevent the power supply line 206 from generating noise or falling off due to displacement relative to the plate 4. The sealed connection between the sealing member 5 and the threading hole 402 and the sealed connection between the power supply line 206 and the perforation of the sealing member 5 can prevent the drying air in the air duct from leaking out of the air duct from the threading hole 402 and the perforation of the sealing member 5, respectively. This ensures sufficient drying air volume in the air duct and improves the drying efficiency of the clothing processing equipment.

[0112] Preferably, the outer diameter of the seal 5 is larger than the inner diameter of the wire hole 402. The seal 5 forms an interference fit with the wire hole 402 through its own deformation, thereby allowing the seal 5 to be installed in the wire hole 402.

[0113] Preferably, the inner diameter of the sealing element 5 is smaller than the outer diameter of the light source power line 206. The sealing element 5 forms an interference fit with the light source power line 206 through its own deformation, thereby forming a seal between the light source power line 206 and the perforation on the sealing element 5.

[0114] By forming a sealed connection between the seal 5 and the wire hole 402, and simultaneously forming a sealed connection between the power supply line 206 of the light source and the hole of the seal 5, the drying air in the air duct can be prevented from leaking out of the air duct from the wire hole 402 and the hole of the seal 5, thereby ensuring sufficient drying air volume in the air duct and improving the drying efficiency of the air duct of the garment processing equipment.

[0115] Optionally, in one implementation of this embodiment, such as Figure 3-5 As shown,

[0116] The plate 4 is provided with a wire fixing component 6, which is used to fix the power supply line 206 of the light source 2.

[0117] In this embodiment, a wire fixing component 6 is also provided on the plate 4. The wire fixing component 6 can fix the light source power line 206 of the light source 2 to the surface of the plate 4, so as to prevent the light source power line 206 from swinging back and forth on the plate 4 and interfering with other components. At the same time, fixing the light source power line 206 of the light source 2 to the surface of the plate 4 can also reduce the wear of the light source power line 206 caused by shaking and improve the service life of the light source power line 206.

[0118] Preferably, the wire fixing component 6 can be either a wire fixing clip or a wire fixing hole. In this embodiment, both a wire fixing clip and a wire fixing hole can be provided on the plate 4 at the same time. The power supply line 206 of the light source is fixed by the cooperation of the wire fixing hole and the wire fixing clip, so as to improve the connection strength between the power supply line 206 of the light source and the plate 4.

[0119] Fixing the power supply line 206 of the light source 2 to the surface of the board 4 with a fastener can prevent the power supply line 206 from swinging back and forth on the board 4 and interfering with other components. It can also reduce the wear of the power supply line 206 caused by the swinging and improve the service life of the power supply line 206.
