Description

Technical Field

[0001] The invention relates to the technical field of daily necessities, in particular to a socks deodorizing finishing device. Background Art

[0002] In daily life, socks are essential items for people to wear daily, and their hygiene and odor issues have always been a concern. At present, socks often stink during use, which not only affects the wearing experience, but also may breed a large number of bacteria, posing a potential threat to foot health.

[0003] Traditional sock storage methods, such as randomly piling socks in drawers or closets, or simply stuffing them on shoe racks, often lack good ventilation conditions. In this closed or semi-closed environment, the sweat on the socks cannot evaporate in time, and moisture accumulates, further aggravating the reproduction of microorganisms and the generation of odors.

[0004] In addition to poor ventilation, the sweat absorbed by the socks during wearing causes the socks themselves to be in a high humidity state. If the humidity cannot be effectively reduced during storage, it will create a more suitable environment for the growth of microorganisms. Moreover, high humidity may also cause damage to the sock material, such as mold, which will also aggravate the odor problem.

[0005] In view of this, this application is hereby filed. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please refer to the attached Figure 1 To Attachment Figure 8 , the present invention provides a technical solution:

[0031] A socks deodorizing finishing device comprises a finishing cabinet 1 and a placing drawer 2, wherein a ventilation fan 4 is arranged on the back of the finishing cabinet 1, and a placing plate 3 is installed on the inner bottom surface of the placing drawer 2, wherein the placing plate 3 is in a criss-cross grid shape; the placing plate 3 comprises an air cavity 301 which is opened in the placing plate 3 and has a smaller cross section than the placing plate 3, and has a plurality of criss-cross interconnected air cavities, wherein at least one of the air cavities 301 is connected to an air inlet end of the ventilation fan 4; and a plurality of blowing holes 302 which are opened at intervals on the top surface of the placing plate 3, and the plurality of blowing holes 302 are all connected to the air cavity 301.

[0032] The ventilation fan 4 is located at the back of the storage cabinet 1. When the ventilation fan 4 is started, air is sucked in. After passing through the ventilation fan 4, the air enters the air cavity 301 of the placement plate 3. The air cavity 301 is a space opened inside the placement plate 3 and has a cross-section smaller than the placement plate 3. Multiple air cavities 301 are criss-crossed and interconnected, and at least one air cavity 301 is connected to the air inlet end of the ventilation fan 4. The air flows in the air cavity 301 and is dispersed to various parts.

[0033] Afterwards, air is blown out from the multiple blowing holes 302 that are spaced apart on the top surface of the placement plate 3. Since the blowing holes 302 are distributed on the entire top surface of the placement plate 3, the blown air can evenly cover the socks placed on the placement plate 3. The air continues to flow, taking away the odor, moisture, etc. emitted from the socks, maintaining the freshness and dryness of the air around the socks, ensuring that the entire socks can be well ventilated, and there will be no problem of odor or moisture residue due to poor local ventilation.

[0034] The design of the ventilation fan 4 and the placement plate 3 ensures that the air around the socks is continuously renewed, and can promptly remove odors caused by sweating or other reasons. This prevents odors from accumulating on the socks, greatly reduces the odor of the socks, improves the hygiene of the socks, and improves the wearing experience.

[0035] Moreover, the flow of air helps to speed up the drying of socks. For socks that have just been washed and still have a certain amount of moisture, or socks that are damp due to sweating on the feet during daily wear, this ventilation design can make the socks return to a dry state faster. A dry environment is not conducive to the growth of microorganisms such as bacteria and fungi, thereby reducing the problem of sock odor caused by the growth of microorganisms.

[0036] Please refer to the attached Figure 2 and attached Figure 8 In a specific implementation of the present embodiment, a controller 5 is provided on the back of the storage cabinet 1, and the controller 5 is electrically connected to the ventilation fan 4. A rotary switch 501 is installed on the top surface of the controller 5. An adjusting cavity 502 is provided on the side of the controller 5. The adjusting cavity 502 is connected to the interior of the storage cabinet 1. A desiccant pendant 503 is provided in the adjusting cavity 502. One end of a pull rope 504 is coiled on the rotary switch 501, and the other side of the pull rope 504 is inserted into the adjusting cavity 502 from one side and fixedly connected to the desiccant pendant 503.

[0037] The desiccant pendant 503 is made of activated carbon material, and a torsion spring is provided in the rotary switch 501 . The torque of the torsion spring is equal to the weight of the desiccant pendant 503 at 50% air humidity.

[0038] The hygroscopic pendant 503 is located in an adjustment chamber 502 connected to the interior of the storage cabinet 1. When the air humidity inside the storage cabinet 1 changes, the hygroscopic pendant 503 will absorb or release moisture accordingly. Since the weight of the hygroscopic pendant 503 changes with its degree of moisture absorption, when the air humidity increases, the hygroscopic pendant 503 absorbs moisture and its weight gradually increases.

[0039] The rotary switch 501 is mounted on the top surface of the controller 5, and a torsion spring is arranged inside the rotary switch 501. The torque of the torsion spring is set to be equal to the weight of the moisture absorbing weight 503 when the air humidity reaches a certain value (such as 50%).

[0040] The rotary switch 501 can be selected as a potentiometer, a relay circuit, or a Hall sensor circuit. This solution is a prior art, so it will not be described in detail.

[0041] When the weight of the desiccant pendant 503 exceeds the torque of the torsion spring due to moisture absorption, it applies tension to the rotary switch 501 through the pull rope 504. One end of the pull rope 504 is coiled around the rotary switch 501, and the other end is inserted from one side of the adjustment cavity 502 and fixedly connected to the desiccant pendant 503. This connection method enables the weight change of the desiccant pendant 503 to be effectively transmitted to the rotary switch 501, thereby triggering the rotation of the rotary switch 501.

[0042] The rotation of the rotary switch 501 can turn on the ventilation fan 4 and control the power of the ventilation fan 4 according to the humidity change. The higher the humidity, the greater the power of the ventilation fan 4, which accelerates the air circulation to discharge moisture and realizes automatic humidity regulation.

[0043] The automatic humidity adjustment mechanism can automatically control the start and stop and power of the ventilation fan 4 according to the humidity in the cabinet. It effectively maintains the appropriate humidity in the cabinet, prevents the socks from getting moldy and smelly due to high humidity, protects the quality of the socks, extends the service life of the socks, reduces the trouble of manual operation by users, and ensures that the device can work effectively in different humidity environments.

[0044] Please refer to the attached Figure 8 In a specific implementation of the present embodiment, an adapter frame is provided at the center of the inner top of the adjusting cavity 502, and a through hole adapted to the pull rope 504 is opened at the center of the bottom surface of the adapter frame. After the pull rope 504 is inserted from one side of the adjusting cavity 502, it is fixedly connected to the top surface of the desiccant pendant 503 through the through hole.

[0045] The adapter frame is located at the center of the inner top of the adjustment chamber 502, so that the other end of the pull rope 504 can be located at the center of the adjustment chamber 502, which can make the moisture-absorbing pendant 503 away from the side wall of the adjustment chamber 502, so that it will encounter less friction resistance when rising and falling, making the control effect of the rotary switch 501 more precise.

[0046] Please refer to the attached Figure 2 and attached Figure 7 In a specific implementation of the present embodiment, a funnel 401 is provided on the outside of the ventilation fan 4 , and an air hole is opened at the end of the funnel 401 near the storage cabinet 1 , and the air hole is communicated with the air cavity 301 .

[0047] The funnel 401 arranged outside the ventilation fan 4 plays the role of concentrating and guiding air. When the ventilation fan 4 is running, it draws in external air.

[0048] The special shape of the funnel 401 can make the air in a wider range converge to the center, and the air holes opened near the end of the storage cabinet 1 are connected with the air cavity 301 in the placement plate 3, so that the converged air can enter the air cavity 301 accurately and efficiently. In addition, according to the narrow tube effect (the flow rate remains unchanged, the flow channel becomes smaller, and the flow rate increases), the design of the funnel 401 can also accelerate the flow rate of the air entering the air cavity 301, increase the speed of the air blown out of the blowing hole 302, and ventilate the socks more effectively.

[0049] The design of the funnel 401 increases the amount of air entering the air cavity 301 and the air flow rate, allowing more air to flow through the socks, taking away the odor and moisture emitted by the socks more quickly, thereby enhancing the drying and deodorizing function of the ventilation system on the socks. Compared with the case without the funnel 401, the freshness and dryness of the air around the socks can be maintained more efficiently.

[0050] Moreover, by guiding the air to the air holes, disordered flow and loss of air are avoided, and the air can enter the air cavity 301 more accurately, making the entire ventilation system run more orderly, improving the utilization efficiency of air during the ventilation process, and helping to further optimize the anti-odor performance of the device.

[0051] Please see attached Figure 1 and attached Figure 3 In a specific implementation of the present embodiment, a ventilation hole 201 is provided on the front of the placement drawer 2, and the ventilation hole 201 is a mesh grille. A guide groove 202 is provided on the side of the placement drawer 2. Guide rails 101 are provided on both sides of the inner wall of the storage cabinet 1. The guide rails 101 and the guide grooves 202 are matching rectangular blocks and rectangular grooves. The guide grooves 202 are slidably connected to the guide rails 101, and the placement drawer 2 can slide back and forth along the extension direction of the guide rails 101.

[0052] A connection groove 303 is provided at the end of the placement plate 3 near the ventilation fan 4, a docking block 403 is fixedly connected to the storage cabinet 1, the docking block 403 is connected to the air hole, and a sealing gasket 404 is provided at the end of the docking block 403 near the placement drawer 2.

[0053] The air holes 201 on the front of the placing drawer 2 are of a mesh grille structure. When the ventilation fan 4 is started, air enters the air cavity 301 from the air holes of the funnel 401 outside the ventilation fan 4, and then blows out from the blowing holes 302 of the placing plate 3. After the socks are ventilated, the air is discharged through the air holes 201 with the moisture and odor emitted by the socks. The design of the mesh grille can ensure the smooth flow of air and prevent dust and other impurities from entering the placing drawer 2, maintaining the cleanliness of the environment inside the placing drawer 2, so that the air forms an effective circulation in the placing drawer 2.

[0054] The mesh grille design of the air holes 201 allows air to circulate to expel odor and moisture, while preventing dust and other pollutants from entering, helping to keep the socks storage environment fresh and hygienic, which helps to reduce the possibility of socks being contaminated by the outside world, further extending the service life of the socks, and also better maintaining the anti-odor effect of the device.

[0055] The guide grooves 202 on the sides of the placement drawer 2 cooperate with the guide rails 101 on both sides of the inner wall of the storage cabinet 1. The two are adapted rectangular blocks and rectangular groove structures, which enable the placement drawer 2 to slide back and forth smoothly along the extension direction of the guide rails 101.

[0056] The sliding design of the placement drawer 2 greatly improves the convenience of using the device. The user does not need to operate laboriously in a fixed space. The user can easily place or take out the socks by simply pulling out the placement drawer 2. This user-friendly design can save the user's time and energy and improve the efficiency of daily sock sorting.

[0057] The connection groove 303 at the end of the placement plate 3 near the ventilation fan 4 cooperates with the docking block 403 fixedly connected in the storage cabinet 1, and the docking block 403 is connected to the air hole, so as to guide the airflow generated by the ventilation fan 4 into the air cavity 301 of the placement plate 3. The sealing gasket 404 at the end of the docking block 403 near the placement drawer 2 can effectively seal the docking point to prevent air leakage.

[0058] The design of the docking block 403 and the sealing pad 404 ensures the sealing of the ventilation system, so that the air will not leak during the transmission process from the ventilation fan 4 to the air cavity 301 of the placement plate 3. The stable air pressure and flow ensure that the ventilation system can operate continuously and efficiently, thereby stably providing good ventilation conditions for the socks and enhancing the overall deodorization and drying capabilities of the device.

[0059] Please see attached Figure 1 , Attachment Figure 2 And attached Figure 5 In a specific implementation of the present embodiment, there are multiple placement drawers 2 distributed in a linear array in the storage cabinet 1, the number and position of the docking blocks 403 are adapted to the placement drawers 2, and the back of the funnel 401 is connected to a connecting pipe 402, and the connecting pipe 402 is in a long strip shape, one side of which is connected to the funnel 401, and the other side is provided with a number of forks corresponding to the docking blocks 403, and the forks are respectively connected to the corresponding docking blocks 403.

[0060] The placement drawers 2 are distributed in a linear array in the storage cabinet 1, and each placement drawer 2 has a corresponding docking block 403. One side of the long connecting pipe 402 connected to the back of the funnel 401 is connected to the funnel 401, and the number of forks on the other side corresponds to the number of docking blocks 403 and is connected to them respectively.

[0061] By connecting the pipe 402 and the fork design, the air sucked in by the ventilation fan 4 can be evenly distributed to multiple placement drawers 2, thereby achieving comprehensive ventilation of all socks. This design avoids the problem of poor ventilation of some socks, ensures the continuous renewal of the air around the socks in each placement drawer 2, and effectively removes the odor and moisture emitted by the socks, thereby improving the anti-odor ability of the entire device.

[0062] When the ventilation fan 4 is working, air is sucked into the funnel 401, and then evenly distributed to each docking block 403 through the connecting pipe 402 and its branch, and then enters the air cavity 301 of the placement plate 3 corresponding to each placement drawer 2. The air blown out from the air cavity 301 through the blowing hole 302 ventilates the socks in each placement drawer 2, and then the air is discharged from the air hole 201 on the front side of the placement drawer 2, forming a complete air circulation, ensuring that the socks in each placement drawer 2 can get a good ventilation effect.

[0063] Multiple placement drawers 2 are distributed in the storage cabinet 1 in a linear array, which can make full use of the space of the storage cabinet 1 and facilitate the classification and storage of socks. For example, socks can be classified and placed according to the type of socks (such as sports socks, daily socks), family members, etc. Each placement drawer 2 has an independent ventilation system, which not only ensures the ventilation effect, but also facilitates the user to organize and find socks, thereby improving the convenience of use.
