[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figures 1 to 5 As shown in the figure, a low standby power charger according to an embodiment of the present invention includes a low standby power charger body 1; the low standby power charger body 1 is provided with a protection module, which can cut off the power to the low standby power charger body 1 when the mobile phone is fully charged; the low standby power charger body 1 is provided with a charging module.

[0029] One side of the low standby power charger body 1 is connected to a connector 2 by screws. The connector 2 has a through hole and a wire 3 is provided inside the connector 2. The wire 3 passes through the through hole and a copper sheet 23 is provided at one end of the wire 3 inside the connector 2. The copper sheet 23 is attached to the charging module and is electrically connected. The other end of the wire 3 is electrically connected to a plug 4. A winding mechanism for winding the wire 3 is provided inside the connector 2.

[0030] An alarm module is provided inside the low standby power charger body 1. A connecting ring 5 is fixedly connected to the connector 2 by a bracket. A detection ring 6 made of elastic material is fixedly connected to the inner wall of the connecting ring 5. The detection ring 6 has a hollow structure inside and a pressure sensor 7 for activating the alarm module is provided inside the detection ring 6. The detection ring 6 is sleeved on the wire 3.

[0031] When a mobile phone needs to be charged, the low standby power charger body 1 is plugged into a socket to provide power. Then, the wire 3 is pulled out from the connector 2, and the plug 4 is inserted into the phone's charging port. During the process of pulling out the wire 3, the wire 3 passes through the detection ring 6. If the surface of the wire 3 is damaged, the inner wall of the detection ring 6 will deform and fill the damaged area. At this time, the air pressure inside the detection ring 6 will change and be sensed by the pressure sensor 7, which will activate the alarm module, thereby alerting the user that the wire 3 is damaged. This prevents unstable current and short circuits. Stable current helps reduce power consumption during the charging process. After the phone is fully charged, the protection module will cut off the power to the low standby power charger body 1 to prevent the low standby power charger body 1 from continuously charging the phone, causing unnecessary energy consumption and further reducing power consumption.

[0032] The connecting ring 5 has a hollow internal structure. A push plate 8 is slidably connected inside the connecting ring 5. A first spring is fixedly connected between the bottom surface of the push plate 8 and the inner wall of the connecting ring 5. A set of liquid outlet holes 9 communicating with the inside of the connecting ring 5 are opened on the inner wall of the connecting ring 5. Marking liquid is stored above the push plate 8. A drive mechanism for moving the push plate 8 is provided inside the connector 2. When the wire 3 is damaged and passes through the detection ring 6, the drive mechanism will push the push plate 8, causing the push plate 8 to push the marking liquid. At this time, the marking liquid will spray out from the liquid outlet hole 9 onto the wire 3. The marking position of the marking liquid is above the damaged area of ​​the wire 3, which makes it easier for subsequent personnel to find the damaged area for timely treatment.

[0033] The connector 2 has a heat dissipation groove, and a first sliding groove 11 communicating with the heat dissipation groove is provided inside the connector 2. A sealing plate 10 is provided inside the first sliding groove 11 to seal the heat dissipation groove. A second spring is fixedly connected between the side of the sealing plate 10 away from the plug 4 and the inner wall of the first sliding groove 11. The driving mechanism can drive the sealing plate 10 to move. A temperature measurement module is provided inside the low standby power charger body 1. When the low standby power charger body 1 of this application is in use, heat will be generated inside. If the heat is too high, it will increase the power consumption and also cause safety hazards. At this time, the internal temperature can be measured by the temperature measurement module. If the measured temperature is too high, the driving mechanism will drive the sealing plate 10 to stop sealing the heat dissipation groove. At this time, the heat inside the low standby power charger body 1 can be dissipated from the heat dissipation groove, thereby reducing power consumption and safety hazards.

[0034] The driving mechanism includes an electromagnet 13 that is magnetically attracted to the sealing plate 10 within the first slide groove 11. The sealing plate 10 is made of magnetic material and has a hollow internal structure. A movable plate 15 is slidably connected inside the sealing plate 10. A third spring is fixedly connected between the side of the movable plate 15 away from the second spring and the inner wall of the sealing plate 10. A connecting rod 14 is fixedly connected to the side of the movable plate 15 away from the third spring. The connecting rod 14 is slidably connected to the side of the sealing plate 10 near the second spring. A connecting pipe 16 connects the sealing plate 10 and the connecting ring 5.

[0035] The electromagnet 13 in this application has two positions. In the low magnetic force position, when it attracts the sealing plate 10, it will not allow the inner wall of the first slide groove 11 to push the connecting rod 14. In the high magnetic force position, it can attract the sealing plate 10 and allow the inner wall of the first slide groove 11 to push the connecting rod 14. In this application, when the temperature measurement module detects a high temperature, it will activate the electromagnet 13 and put it in the low magnetic force position, so that the sealing plate 10 will no longer seal the heat dissipation groove. When the pressure sensor 7 detects that the wire 3 is damaged, it will also activate the electromagnet 13 and put it in the high magnetic force position. At this time, the sealing plate 10 will be attracted, and then the inner wall of the first slide groove 11 will push the connecting rod 14. At this time, the connecting rod 14 will drive the moving plate 15 to push the gas in the sealing plate 10 into the connecting ring 5 through the connecting pipe 16, and then push the push plate 8 so that the marking liquid can be sprayed from the liquid outlet 9 onto the wire 3. Through the above mechanism, we can realize the function of using a single electromagnet 13 to simultaneously drive multiple components to move.

[0036] The alarm module includes a fixed tube 17 fixedly connected to the low standby power charger body 1, a connection hole 19 on the connector 2, an air inlet end of the fixed tube 17 aligned with the connection hole 19, a whistle 18 inside the fixed tube 17, a sealing plate 10 slidably connected to the inner wall of the connector 2, and a set of heat dissipation holes 21 communicating with the first sliding groove 11 on the inner side wall of the connector 2.

[0037] When the sealing plate 10 is attracted by the first electromagnet 13, it pushes the gas in the first slide groove 11 to be discharged from the heat dissipation hole 21 and the fixing tube 17. Thus, the gas discharged from the heat dissipation hole 21 can dissipate heat inside the low standby power charger body 1. The gas discharged from the fixing tube 17 can pass through the whistle 18, causing the whistle 18 to sound an alarm. At the same time, when the electromagnet 13 is in the low magnetic force position, the electromagnet 13 can be intermittently activated for 2-3 minutes, allowing the electromagnet 13 to drive the sealing plate 10 to move repeatedly, so that the gas in the first slide groove 11 can be repeatedly blown from the heat dissipation hole 21 into the low standby power charger body 1 for continuous heat dissipation. Through the above mechanism, both the alarm effect and the heat dissipation effect inside the low standby power charger body 1 can be achieved.

[0038] The take-up mechanism includes a rotating shaft 26 rotatably connected to the inner wall of the connector 2. A hollow take-up roller 22 is fixedly connected to the surface of the rotating shaft 26. A pair of retaining rings 25 are fixedly connected to the surface of the take-up roller 22. An inlet hole is provided on the side wall of the take-up roller 22. The wire 3 passes through the inlet hole. The copper sheet 23 is rotatably connected to the end of the take-up roller 22 away from the rotating shaft 26. A coil spring 24 is provided between the take-up roller 22 and the inner wall of the connector 2. By pulling the plug 4, the wire 3 can drive the take-up roller 22 to rotate, so that the wire 3 is pulled out from the connector 2. When the plug 4 is released, the coil spring 24 will drive the take-up roller 22 to rotate and reset, so that the wire 3 is wound on the take-up roller 22. At the same time, the wire 3 is limited by the retaining rings 25. The above mechanism can achieve the function of winding the wire 3 to prevent the wire 3 from being too long and inconvenient to carry the low standby power charger body 1.

[0039] The connector 2 has a movable groove near the rotating shaft 26. A locking block 28 is provided in the movable groove. A fourth spring is fixedly connected between the top surface of the locking block 28 and the inner wall of the movable groove. The rotating shaft 26 has a locking groove 27 that engages with the locking block 28. The rotating shaft 26 is provided with a release component that allows the locking block 28 to disengage from the locking groove 27. When the rotating shaft 26 needs to rotate, the release component allows the locking block 28 to disengage from the locking groove 27, after which the rotating shaft 26 can rotate normally. At this time, the wire 3 can be pulled out from the connector 2. Then, the locking block 28 engages with the locking groove 27 again, so that the rotating shaft 26 is fixed. At this time, the wire 3 will be outside the connector 2. When the wire 3 needs to be wound up, the locking block 28 disengages from the locking groove 27, and then the coil spring 24 drives the take-up roller 22 to wind up the wire 3.

[0040] The disengagement assembly includes a third slide groove 29 located at the end of the rotating shaft 26 away from the take-up roller 22. A slide column 30 is slidably connected within the third slide groove 29. A fifth spring is fixedly connected between the slide column 30 and the inner wall of the third slide groove 29. A connecting groove is provided between the locking groove 27 and the third slide groove 29. The locking block 28 is slidably connected to the moving groove, and the rotating shaft 26 is rotatably connected to the connector 2. In this application, by pushing the slide column 30, the gas in the third slide groove 29 enters the locking groove 27 from the connecting groove. Then, the gas pushes the locking block 28 to disengage from the locking groove 27. Then, the wire 3 is pulled, causing the rotating shaft 26 to rotate. After the wire 3 is fully pulled out, the locking block 28 will align with the locking groove 27. At this time, the locking block 28 will engage with the locking groove 27 under the push of the fourth spring.

[0041] Example 2: Figure 6As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a cleaning ring 31 is fixedly connected to the inner wall of the through hole, and bristles 32 are fixedly connected to the inner wall of the cleaning ring 31. The bristles 32 are in contact with the surface of the wire 3. Since the wire 3 inevitably accumulates impurities during daily use, these impurities will affect the detection results when passing through the detection ring 6. At this time, the wire 3 can be cleaned by the bristles 32, so that the wire 3 is cleaned by the bristles 32 when passing through the cleaning ring 31, thereby improving the accuracy of the detection.

[0042] The connector 2 has a second sliding groove 12 that communicates with the heat dissipation groove. A sliding plate 33 is slidably connected to the inner wall of the second sliding groove 12. A sixth spring is fixedly connected between the sliding plate 33 and the inner wall of the second sliding groove 12. The cleaning ring 31 has a hollow structure. A set of air inlets are opened between the cleaning ring 31 and the second sliding groove 12. An air outlet 20 is opened on the inner wall of the cleaning ring 31. In this application, the sealing plate 10 can be manually moved so that the sealing plate 10 repeatedly squeezes the sliding plate 33 to move back and forth. At this time, the sliding plate 33 will push the gas in the second sliding groove 12 into the cleaning ring 31 through the air inlet and then blow it onto the bristles 32 through the air outlet 20, thereby blowing away the impurities on the bristles 32 and improving the cleaning effect on the wire 3.

[0043] Working Principle: When charging a mobile phone, the low standby power charger body 1 is plugged into a socket to provide power. Then, the wire 3 is pulled out from the connector 2, and the plug 4 is inserted into the phone's charging port. During the pulling process, the wire 3 passes through the detection ring 6. If the surface of the wire 3 is damaged, the inner wall of the detection ring 6 will deform and fill the damaged area. At this time, the air pressure inside the detection ring 6 will change, which is sensed by the pressure sensor 7 and triggers the alarm module, thus alerting the user that the wire 3 is damaged, preventing unstable current and short circuits. Stable current helps reduce power consumption during charging. After the phone is fully charged, the protection module will cut off the power to the low standby power charger body 1 to prevent the low standby power charger body 1 from continuously charging the phone and causing unnecessary energy consumption, thus further reducing power consumption. In this application, when the wire 3 is damaged and passes through the detection ring 6, the drive mechanism will push the push plate 8, which will push the marking liquid. At this time, the marking liquid will spray out from the outlet hole 9 onto the wire 3. The marking position of the marking liquid is above the damaged area of ​​the wire 3, which makes it easier for subsequent personnel to find the damaged area and carry out timely treatment.

[0044] The low standby power charger body 1 in this application generates internal heat during use. Excessive heat can increase power consumption and pose a safety hazard. The internal temperature can be measured by a temperature measurement module. If the measured temperature is too high, the drive mechanism will cause the sealing plate 10 to stop sealing the heat dissipation slot. This allows the heat inside the low standby power charger body 1 to dissipate from the heat dissipation slot, reducing power consumption and safety hazards. The electromagnet 13 in this application has two positions: a low magnetic force position attracts the sealing plate 10 without pushing the connecting rod 14 against the inner wall of the first slide groove 11; a high magnetic force position attracts the sealing plate 10, causing the inner wall of the first slide groove 11 to push the connecting rod 14. The temperature measurement module in this application... When the measuring module detects a high temperature, it will activate electromagnet 13, setting it to a low magnetic force position. This will cause the sealing plate 10 to stop sealing the heat sink. When the pressure sensor 7 detects damage to the wire 3, it will also activate electromagnet 13, setting it to a high magnetic force position. At this time, the sealing plate 10 will be attracted, causing the inner wall of the first slide groove 11 to push the connecting rod 14. The connecting rod 14 will then drive the moving plate 15 to push the gas inside the sealing plate 10 into the connecting ring 5 through the connecting pipe 16. This will then push the push plate 8, allowing the marking liquid to be sprayed from the outlet hole 9 onto the wire 3. Through the above mechanism, we can achieve the function of simultaneously driving multiple components to move using a single electromagnet 13.

[0045] When the sealing plate 10 is attracted by the first electromagnet 13, it pushes the gas in the first slide groove 11 to be discharged from the heat dissipation hole 21 and the fixing tube 17. The gas discharged from the heat dissipation hole 21 can dissipate heat from the inside of the low standby power charger body 1. The gas discharged from the fixing tube 17 can pass through the whistle 18, causing the whistle 18 to sound an alarm. Simultaneously, when the electromagnet 13 is in the low magnetic force position, it can be intermittently activated for 2-3 minutes, causing the electromagnet 13 to drive the sealing plate 10 to move repeatedly, allowing the gas in the first slide groove 11 to be repeatedly blown from the heat dissipation hole 21 to the low standby power charger body 1. The device body 1 is continuously cooled. The above mechanism can achieve both the alarm effect and the cooling effect inside the low standby power charger body 1. By pulling the plug 4, the wire 3 can drive the take-up roller 22 to rotate, so that the wire 3 is pulled out from the connector 2. When the plug 4 is released, the coil spring 24 will drive the take-up roller 22 to rotate and reset, so that the wire 3 is wound on the take-up roller 22. At the same time, the wire 3 is limited by the retaining ring 25. The above mechanism can achieve the function of winding the wire 3 to prevent the wire 3 from being too long and inconvenient to carry the low standby power charger body 1.

[0046] When the shaft 26 needs to rotate, the release assembly allows the locking block 28 to disengage from the slot 27, after which the shaft 26 can rotate normally. At this time, the wire 3 can be pulled out from the connector 2. Then, the locking block 28 engages with the slot 27 to fix the shaft 26. At this time, the wire 3 will be outside the connector 2. When the wire 3 needs to be wound up, the locking block 28 disengages from the slot 27, and then the coil spring 24 drives the take-up roller 22 to wind up the wire 3. The application pushes the slide column 30 to allow the gas in the third slide groove 29 to enter the slot 27 from the connecting groove. The gas will then push the locking block 28 to disengage from the slot 27, and then pull the wire 3 to rotate the shaft 26. After the wire 3 is fully pulled out, the locking block 28 will align with the slot 27. At this time, the locking block 28 will engage with the slot 27 under the push of the fourth spring.
