Description

Technical Field

[0001] This utility model belongs to the field of power cord protection technology, and in particular relates to a small household power cord winding and protection device. Background Technology

[0002] Since the beginning of the 21st century, the variety of household appliances has increased daily. Many of these small appliances have extremely long power cords, and few people retract them, creating numerous safety hazards, especially for families with young children. Power cord retractors can effectively reduce most of these safety hazards.

[0003] Patent application CN202310092166.X discloses a household power cord winding and storage device, including a first mounting frame, a first fixing seat, a second mounting frame, and a first rotating shaft. The first fixing seats are symmetrically fixed to the top left and right sides of the bottom panel of the first mounting frame. The second mounting frame is slidably connected between the two first fixing seats, and the first rotating shaft is rotatably connected to the middle of the second mounting frame. The power strip is stored inside the first mounting frame. Because the first mounting frame is relatively large, it is not easily forgotten or lost. The limiting roller tightly holds the power cord, ensuring it is securely wound around the first winding wheel and will not easily come loose. Even during vigorous movement or when the device is inverted, the power strip will not fall out and the power cord will not scatter.

[0004] In the existing technology, the power cord is wound up by a swivel and secured by a limiting roller to prevent it from coming loose, thus achieving the purpose of winding up the power cord. However, there are still many shortcomings in its overall use.

[0005] First, the power cord is used in an unpredictable environment. When the cord is exposed to the environment, dust, dirt, and moisture easily stick to its surface, which can cause the cord to age and rot. Although the existing winding device can complete the winding, it cannot clean the dirt or moisture on the surface of the cord during the winding process. A large amount of moisture and dirt will enter the protective shell with the cord and accumulate during winding, which can easily lead to the aging and corrosion of the power cord, posing a safety hazard.

[0006] Secondly, the existing winding device's protective casing cannot provide ventilation and drying, resulting in the inability to handle the heat or moisture generated by a large number of power cords after use, which further increases the possibility of power cord aging and corrosion.

[0007] Finally, power rewind devices are usually small in size and can easily be placed in a corner of a household appliance, making it easy for users to forget where they are located, and they lack warning signs. Utility Model Content

[0008] To overcome the shortcomings of the prior art, this utility model provides a small household power cord winding and protection device. By incorporating a cleaning sleeve, a cleaning pad, a dehumidifier, and a light bar, the device can scrape away moisture and dirt from the outside of the power cord during winding, keeping the inside of the protective housing clean and dry, preventing loss, and improving the overall service life of the device and the power cord.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a small household power cord winding and protection device, comprising a housing, a hollow winding cylinder rotatably disposed at the center of the housing, a cable passage opening disposed on the outer surface of the housing, a removable cleaning pad disposed on the outer end face of the cable passage opening, a cleaning sleeve disposed on one side of the cleaning pad on the end face of the cable passage opening, a cleaning conical hole concentrically arranged on the cleaning sleeve, a plurality of dehumidifying cylinders disposed on the inner circular surface of the housing, an opening disposed at both ends of the dehumidifying cylinders on the end face of the housing, and an adsorption rod slidably disposed in the opening at one end of the dehumidifying cylinder.

[0010] Preferably, a knob is provided at one end of the take-up hollow cylinder connected to the outside of the shell, a starting hole is provided at the other end of the take-up hollow cylinder, and a winding hole is provided on the outer circle of the middle part of the take-up hollow cylinder connected to the shell.

[0011] Preferably, the narrowest section of the cleaning cone hole is provided with a scraping protrusion.

[0012] Preferably, an annular groove is provided on the outside of the cleaning cone hole at the port of the cleaning sleeve, and a plurality of sleeve drainage holes are provided on the inner circular surface of the annular groove.

[0013] Preferably, the outer end face of the conduit is provided with multiple connecting holes, and a connecting rod is provided in each of the multiple connecting holes with an interference fit. One end of the connecting rod is connected to the cleaning sleeve.

[0014] Preferably, a conical, inclined drainage groove is provided between the cleaning sleeve and the conduit opening.

[0015] Preferably, spring grooves are provided on both end faces inside the housing, and sliders are slidably disposed in the spring grooves. Spring damping is provided between the upper end face of the slider and the inner surface of the spring groove. A spring is provided between the two spring dampings, and a bidirectional threaded rod is connected between the two sliders. A guide slider is drivenly connected to the bidirectional threaded rod, and a guide hole is provided on the end face of the guide slider.

[0016] Preferably, the outer surface of the housing is provided with multiple anti-slip grooves, wherein a corresponding number of LED grooves can be set in the multiple anti-slip grooves as needed, and low-power LEDs are set in the LED grooves.

[0017] Preferably, each of the multiple dehumidifier cylinders has a detachable annular mesh cover on both sides of the end face of the housing.

[0018] Preferably, a humidity detector is provided on the outside of both sliders.

[0019] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0020] (1) This utility model, through the setting of cleaning soft sleeve and cleaning soft pad, as well as through pipe opening and drainage ring groove, can remove dust, dirt and moisture from the surface of the power cord when it is wound up, thereby preventing moisture and dirt from entering the protective shell, avoiding aging and corrosion of the power cord, and improving safety performance.

[0021] (2) This utility model is equipped with a dehumidifier, an adsorption rod and a humidity detector. The adsorption rod adsorbs the moisture and heat generated by the power cord after use and a small amount of dust inside the protective shell. When the humidity detector alarms, the adsorption rod is replaced in time to ensure that the internal environment of the protective shell is clean and dry, thereby protecting and improving the service life of the power cord.

[0022] (3) By setting up a row of lights and a controller, this utility model can effectively remind the user of the specific location of the power cord rewinding device when it is forgotten. Attached Figure Description

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Reference Appendix Figure 1 Appendix Figure 4 Appendix Figure 6 A household small power cord winding and protection device includes a housing 12, a winding hollow cylinder 10 rotatably disposed at the center of the housing 12, a knob 17 connected to the outside of the housing 12 at one end of the winding hollow cylinder 10, a starting hole 29 at the other end of the winding hollow cylinder 10, a winding hole 28 disposed on the outer circular surface of the middle part of the winding hollow cylinder 10 and the housing 12, and a cable passage 34 disposed on the outer surface of the housing 12.

[0034] Specifically, the power cord connected to the appliance extends outward from the starting hole 29 and is connected to the appliance, while the power cord at one end of the plug is led out from the winding hole 28 and extends out of the cable conduit 34. The end extending out of the cable conduit 34 is connected to the plug. It should be noted that in the process of winding the cable, this application focuses on winding the cable at one end of the plug, while the length of the cable led out from the starting hole 29 is fixed and is not wound. The housing 12 is set outside the appliance by an external bracket or hook during use.

[0035] When the wire needs to be tightened, the knob 17 is rotated clockwise, which will cause the take-up hollow cylinder 10 to rotate, thereby causing the take-up hole 28 to rotate, which in turn causes the wire extending outward from the take-up hole 28 to be wound up, so that the wire outside the housing 12 can be wound into the housing 12 and stored.

[0036] Further, see attached document. Figure 4 Appendix Figure 5 Appendix Figure 7Both sides of the inner end face of the housing 12 are provided with spring grooves 40. A slider 23 is slidably arranged in the spring groove 40. A spring damper 21 is provided between the upper end face of the slider 23 and the inner surface of the spring groove 40. A spring 20 is connected between the two spring dampers 21. A double-sided spiral rod 22 is connected between the two sliders 23. A guide slider 41 is driven and connected to the double-sided spiral rod 22. Humidity detectors 19 are connected to both sides of the guide slider 41. A guide hole 27 is provided on the end face of the guide slider 41. The power cord must pass through the guide hole 27 before it extends outward from the cable outlet 34. The power cord is then taken out of the hollow winding tube 10. During the tightening process, since the power cord also passes through the guide hole 27, and the guide slider 41 outside the guide hole 27 is driven by the bidirectional threaded rod 22, the guide slider 41 slides back and forth on the bidirectional threaded rod 22, thereby evenly distributing the power cord on the surface of the take-up hollow cylinder 10, preventing the power cord from accumulating in a certain section of the take-up hollow cylinder 10. Furthermore, due to the setting of the spring 20, it can slide up and down and adjust its position in time when the diameter of the power coil wound outside the take-up hollow cylinder 10 increases or decreases. The setting of the spring damper 21 can prevent the spring 20 from shaking, ensuring the stability of tightening and improving the winding effect.

[0037] Further, see attached document. Figure 1 Appendix Figure 2 Appendix Figure 3 The outer surface of the housing 12 is provided with multiple anti-slip grooves 31 to increase the overall grip feel of the winding device. A corresponding number of LED recesses 42 can be installed within these anti-slip grooves 31 as needed. The LED recesses 42 connect to low-power LEDs 13. One end of the housing 12 is equipped with a removable and replaceable battery 15 and a controller 16. The battery 15 powers the LEDs 13, and the controller 16 controls the lighting of the LEDs 13. The controller 16 periodically turns on the LEDs 13, causing them to illuminate and attract attention, which can be used to prevent loss and enhance aesthetics.

[0038] Further references Figure 1 Appendix Figure 4 Appendix Figure 5 Multiple dehumidifying cylinders 24 are evenly arranged along the circumferential direction on the inner circular surface of the housing 12. Both ends of the dehumidifying cylinder 24 are provided with openings on the end faces of the housing 12. Since the dehumidifying cylinder 24 protrudes from the inner circular surface of the housing 12, it is similar to a reinforcing rib structure, which can increase the overall strength of the housing 12. Multiple dehumidifying holes 32 are provided on the surface of the dehumidifying cylinder 24. An adsorption rod 30 is slidably arranged in the opening at one end of the dehumidifying cylinder 24. The adsorption rod 30 is made of activated carbon material that can adsorb moisture, which is existing technology and will not be described in detail in this application. It is used to adsorb moisture in the device. Removable annular mesh covers 11 are provided on both end faces of the housing 12 to prevent the adsorption rod 30 from slipping from the opening of the dehumidifying cylinder 24 and to provide a certain degree of shielding.

[0039] Specifically, staff can periodically replace the adsorption rod 30, and the humidity detector 19 will detect the humidity inside the housing 12 and sound an alarm when the humidity is too high, so that the user can replace the adsorption rod 30 in time to prevent it from over-adsorbing and affecting the adsorption efficiency. The adsorption rod 30 is placed inside the dehumidification cylinder 24, so that moisture can be adsorbed inside the adsorption rod 30 through multiple dehumidification holes 32, thereby ensuring the dryness inside the housing 12. One of the reasons for choosing activated carbon as the raw material for the adsorption rod 30 in this application is that activated carbon has good air permeability. The annular mesh cover 11 used to cover the adsorption rod 30 is generally mesh-shaped, that is, when there is wind outside, external air can also pass through the annular mesh cover 11 and the adsorption rod 30 into the housing 12, which can also ensure the air permeability inside the housing 12 and further prevent the accumulation of moisture or heat.

[0040] Further references Figure 4 Appendix Figure 5 Appendix Figure 6 A removable cleaning pad 18 is provided on the outer end face of the conduit 34. The cleaning pad 18 is made of highly breathable sponge absorbent material. A cleaning sleeve 14 is provided on one side of the cleaning pad 18 and the end face of the conduit 34. The cleaning sleeve 14 is made of rubber material. The cleaning sleeve 14 is provided with a cleaning cone hole 39 arranged concentrically with the conduit 34. The cleaning cone hole 39 is wider on the outside and narrower on the inside. A scraping protrusion 25 is provided at the narrowest section of the cleaning cone hole 39.

[0041] Specifically, when the wire is wound into the housing 12 from the outside, the wire will first pass through the cleaning cone hole 39. At this time, any dust particles on the outside of the wire will be scraped off by the cleaning cone hole 39 in turn, and finally move to the scraping protrusion 25. It should be noted that the inner diameter of the scraping protrusion 25 is slightly smaller than the outer diameter of the wire. However, since the cleaning sleeve 14 is made of elastic rubber material, it has a certain elastic deformation ability. Therefore, the wire can still pass through the area of ​​the scraping protrusion 25. However, the scraping protrusion 25 will abut against the outer surface of the wire. Thus, after most of the dust on the outside of the wire has been scraped off, the dust or moisture on the surface of the wire will be further scraped off, ensuring the cleanliness of the wire entering the housing 12. The wire with the moisture and dust scraped off will pass through the cleaning pad 18. After the cleaning pad 18 performs the final cleaning and moisture scraping, the wire will enter the housing 12.

[0042] Furthermore, an annular groove 38 is provided at the outermost part of the cleaning cone hole 39 at the port of the cleaning sleeve 14. Multiple sleeve drain holes 33 are provided on the inner circular surface of the annular groove 38. Dust and water on the surface of the power cord will be scraped off at the scraping groove 25 and flow along the hole surface of the cleaning cone hole 39 to accumulate at the annular groove 38, and fall off at the concave part of the curved surface. Excess water stains will be discharged with the sleeve drain holes 33.

[0043] Furthermore, the outer end face of the conduit 34 is provided with multiple connecting holes 36, and a connecting rod 35 is interference-fitted into the multiple connecting holes 36. One end of the connecting rod 35 is connected to a cleaning sleeve 14. Through the connection holes 36 and the connecting rod 35, the cleaning sleeve 14 can be replaced after long-term use. A conical inclined drainage ring groove 37 is left between the cleaning sleeve 14 and the conduit 34. This drainage ring groove 37 provides a ventilation space between the conduit 34 and the cleaning sleeve 14, allowing the moisture absorbed by the cleaning pad 18 to disperse outwards. On the other hand, the stains scraped off by the cleaning pad 18 can also be discharged outwards with the drainage ring groove 37, thereby improving the cleaning effect on the wire.

[0044] Finally, it should be noted that the connection and fixing of each part of this utility model of a small household power cord winding and protection device can be achieved by conventional mechanical connection structure, and the control system and connection method required between multiple electrical components and driving components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as it can achieve its beneficial effect or the specific actions in the above-mentioned work, it can be implemented.
