DETAILED DESCRIPTION

[0029] The following will be combined with the attached embodiment of the present utility model Figure 1-14 , the technical solutions in the embodiments of the utility model are described in detail.

[0030] like Figure 1-4 As shown, a backpack includes a backpack 1, a solar panel 2 for generating electricity, an electrical component 3 for storing electricity, a first magic sticky soft fleece surface 4 for connection, a first magic sticky spiky fleece surface 5 for connection, a soft fixing sleeve 6 for fixing a clamping device and a clamping device for heating a medicine patch. An interlayer is vertically opened on the outer surface of the backpack 1, and the solar panel 2 is vertically arranged inside the interlayer. The outer surface of the interlayer is transparent, so the solar panel 2 can be exposed to sunlight outside and can generate electricity according to its own characteristics, and the solar panel 2 is electrically connected to the electrical component 3. According to its own characteristics, the solar panel 2 cannot store the electricity after generating it, but the solar panel 2 is electrically connected to the electrical component 3, so at this time, after the solar panel 2 is exposed to sunlight and generates electricity, it will be transmitted to the electrical component 3 for storage.

[0031] like Figure 1-4 As shown, the opening of the interlayer is also sealed with a zipper 68, so the solar panel 2 is easy to take out from the backpack 1 or put into the interlayer of the backpack 1. A groove is provided at the bottom of the inner surface of the backpack 1, and the electrical component 3 is inserted and connected in the groove. Therefore, when the backpack 1 is carried, the electrical component 3 will move synchronously with the backpack 1. The electrical component 3 and the clamping device are also electrically connected. Therefore, when the clamping device needs to work, the electrical component 3 will transmit the electricity generated by the solar panel 2 to the clamping device so that the clamping device can perform hot compress on the person carrying the backpack. The first magic sticky soft fleece surface 4 is arranged on the inner surface of the backpack 1 and the first magic sticky soft fleece surface 4 is located above the electrical component 3. The first magic sticky soft fleece surface 4 is sewn on the inner surface of the backpack 1, and has a beautiful appearance, high firmness and is not easy to deform.

[0032] like Figure 1-4As shown, the first magic sticky hair surface 5 is arranged on the back of the soft fixing sleeve 6, and the first magic sticky hair surface 5 is also connected to the back of the soft fixing sleeve 6 by sewing. The soft fixing sleeve 6 is bonded to the inner surface of the backpack 1 by the first magic sticky hair surface 5 and the first magic sticky soft hair surface 4. Therefore, when the backpack 1 is carried, the soft fixing sleeve 6 will not fall off the backpack 1 easily, and when the backpack 1 shakes, the first magic sticky hair surface 5 and the first magic sticky soft will buffer between the soft fixing sleeve 6 and the backpack 1 to avoid misalignment between the soft fixing sleeve 6 and the backpack 1. There are three groups of clamping devices, all of which are arranged inside the soft fixing sleeve 6, and the three groups of clamping devices are respectively located at the shoulders and neck of the soft fixing sleeve 6. A medicine bag placement area 67 for placing the clamping device is sewn inside the soft fixing sleeve 6. After the medicine bag is placed inside the clamping device, the clamping device and the medicine bag will be placed together in the medicine bag placement area 67 for fixation.

[0033] like Figure 4-6 As shown, the soft fixing sleeve 6 includes a back neck piece 61, a back piece 62, a shoulder piece 63, an upper arm piece 64, an upper arm tightening belt 65 and an auxiliary tightening belt 66. The back neck piece 61 is arranged above the back piece 62 and is connected to the back piece 62 by sewing. When the backpack 1 is carried, the back neck piece 61 will be tightly attached to the cervical vertebrae of the wearer under the action of the auxiliary tightening belt 66 to ensure that when the clamping device is working, the medicine bag inside the clamping device can provide hot compress to the cervical vertebrae of the wearer. There are two groups of shoulder pieces 63, which are respectively located at the two ends of the back piece 62, and the top ends of the two groups of shoulder pieces 63 are connected to the back piece 62 by sewing. Therefore, when the backpack 1 is carried, the two groups of shoulder pieces 63 can respectively wrap the shoulders of the wearer. The auxiliary tightening belt 66 is horizontally arranged at the front end of the back piece 62, and the two ends of the auxiliary tightening belt 66 are respectively connected to the two groups of shoulder pieces 63 by buckles.

[0034] like Figure 4-6 As shown, when the two groups of shoulder pieces 63 wrap around the shoulders, the auxiliary tightening straps 66 can ensure that the two groups of keyboards can correctly wrap around the shoulders of the person carrying the backpack 1, and the auxiliary tightening straps 66 can also adjust the distance between the two groups of shoulder pieces 63 according to the body size of the person carrying the backpack 1, one end of the two groups of shoulder pieces 63 are connected to the back piece 62, and the other ends of the two groups of shoulder pieces 63 are connected to a group of upper arm pieces 64, and the upper arm pieces 64 are also connected to the shoulder pieces 63 by sewing. When the backpack 1 is carried, the two groups of upper arm pieces 64 can wrap around the arms of the person carrying the backpack 1, one end of the two groups of upper arm pieces 64 are connected to the shoulder pieces 63, and the other ends of the two groups of upper arm pieces 64 are transversely connected to the upper arm tightening straps 65, and the upper arm tightening straps 65 are also connected to the upper arm pieces 64 by sewing. Therefore, when the upper arm pieces 64 wrap around the arms, the upper arm tightening straps 65 can transversely wrap around the patient's arms.

[0035] like Figure 4-6As shown, when the upper arm tightening strap 65 wraps the patient's arm laterally, the upper arm piece 64 will be fixed on the arm of the person carrying the patient to prevent the upper arm piece 64 from not wrapping the arm properly, thereby causing the medicine pack inside the shoulder piece 63 to be unable to properly heat the shoulders of the person carrying the patient. The insides of the two groups of shoulder pieces 63 and the back neck piece 61 are provided with a medicine pack placement area 67 for placing a compression device. The opening of each group of medicine pack placement area 67 is sealed with a zipper 68, and the inside of each group of medicine pack placement area 67 is provided with an elastic band 68, and both ends of the elastic band 68 are sewn on the shoulder piece 63 and the back neck piece 61. Therefore, if you want to place the medicine pack inside the soft fixing sleeve 6, you only need to pull the zipper 68 to expose the space inside the medicine pack placement area 67, and then pull the elastic band 68 laterally.

[0036] like Figure 4-6 As shown, after pulling the elastic band 68 laterally to make the elastic band 68 disengage from the shoulder piece 63 and the back neck piece 61, the medicine pack is placed at the bottom of the elastic band 68 and then the elastic band 68 is loosened to press the elastic band 68 on the top of the medicine pack to fix the medicine pack, and then the zipper 68 is pulled again to seal the opening of the medicine pack placement area 67.

[0037] like Figure 7 As shown, the electrical component 3 includes a shell 31, a fixing buckle 32, a battery 33 and a micro air pump 34. The interior of the shell 31 is hollow and the four corners of the outer surface of the shell 31 are fixedly connected with the fixing buckles 32. The inside of the groove on the inner surface of the backpack 1 is provided with slots corresponding to the four groups of fixing buckles 32. Therefore, if you want to put the shell 31 into the inside of the groove on the inner surface of the backpack 1, just ensure that the fixing buckles 32 at the four corners of the shell 31 are squeezed into the corresponding slots. At this time, the shell 31 will be embedded in the inside of the groove of the backpack 1 under the action of the fixing buckle 32, thereby ensuring that the shell 31 will not easily fall out of the inside of the groove of the backpack 1. The battery 33 is vertically arranged inside the shell 31 and fixedly connected to the bottom plate inside the shell 31 with screws.

[0038] like Figure 7 As shown, a USB interface is provided on the battery 33, so when electrically connecting the clamping device and the battery 33, it is only necessary to insert the connecting wire into the USB interface on the battery 33. The micro air pump 34 is also fixedly connected to the bottom plate inside the shell 31 by screws, and the micro air pump 34 and the battery 33 are parallel to each other. The battery 33 and the micro air pump 34 are also electrically connected, so when you want to start the micro air pump 34, the battery 33 can provide power support to the micro air pump 34. The micro air pump 34 is connected to the air nozzle 86 of the clamping device by an air duct, so when the micro air pump 34 is working, the gas will be transmitted to the air nozzle 86 through the air duct, and then transmitted to the air bag 76 inside the compression device through the air nozzle 86.

[0039] like Figure 8-10 As shown, the clamping device includes a net bag 71, a main body 72, insulation cotton 73, a heating film 74, a thermistor 75, an airbag 76, and a fixing mechanism 8. The net bag 71 is arranged on one side of the main body 72 and is connected to the main body 72 by sewing. A second magic sticky fur surface is sewn horizontally at the opening of the net bag 71, and a second magic sticky fur surface is horizontally arranged at a position corresponding to the opening of the net bag 71 on the main body 72, and the second magic sticky fur surface is also sewn on the main body 72. When placing a medicine package, the second magic sticky fur surface can be torn off from the second magic sticky fur surface through the net bag 71. After the second magic sticky fur surface is torn off from the second magic sticky fur surface, the opening of the net bag 71 will be opened, and then the medicine package is placed inside the net bag 71, and then the second magic sticky fur surface is re-pasted on the second magic sticky fur surface to seal the opening of the net bag 71.

[0040] like Figure 8-10 As shown, the heat-insulating cotton 73 is vertically arranged inside the main body 72 and connected to the inner wall of one side of the main body 72 by sewing. When the heating film 74 is working, the heat-insulating cotton 73 will seal and store the heat generated by the heating film 74 inside the main body 72 to avoid heat loss of the heating film 74. The heating film 74 is vertically arranged on one side of the main body 72 and connected to the inner wall of the main body 72. The heating film 74 is electrically connected to the thermistor 75. Therefore, when the heating film 74 is working, the generated heat will be transmitted to the medication pack and the soft fixing sleeve 6 through the main body 72, causing the soft fixing sleeve 6 to heat up and heat the skin near the back neck piece 61 and the shoulder piece 63 through the soft fixing sleeve 6, so as to perform hot compress on the shoulders and cervical vertebrae.

[0041] like Figure 8-10 As shown, the thermistor 75 is arranged inside the main body 72 and connected to the heating film 74, and the thermistor 75 is also connected to the battery 33 of the electrical component 3. The resistance value of the thermistor 75 will change with the increase of temperature. Therefore, when the temperature of the heating film 74 is too high, the resistance value of the thermistor 75 will increase to reduce the power of the heating film 74 or directly cut off the power of the heating film 74 to prevent the heating film 74 from being too high and causing burns to the shoulders and back of the neck. The airbag 76 is arranged inside the main body 72 and is located in the middle of the heating film 74 and the insulation cotton 73, and the airbag 76 is connected to the insulation cotton 73 by a fixing mechanism 8. When the airbag 76 expands, it will deform and begin to squeeze the medicine bag inside the net bag 71, so that the medicine bag is closer to the skin of the back of the neck and shoulders.

[0042] like Figure 11-14As shown, the fixing mechanism 8 includes a fixing tube 81, a pipe 82, a clamping block 83, a fixing bolt 84, a fixing nut 85 and an air nozzle 86. There are two groups of fixing tubes 81, both of which are arranged inside the airbag 76, and the two groups of fixing tubes 81 are connected to the airbag 76 and the two groups of fixing tubes 81 are parallel to each other. A slot is opened inside the body 72, and the pipe 82 is transversely arranged in the slot of the body 72. Both ends of the pipe 82 pass through the insulation cotton 73 and are respectively arranged inside the two groups of fixing tubes 81. Therefore, after the micro air pump 34 is started, the compressed air will flow into the interior of the airbag 76 after being diverted through the pipe 82, and the airbag 76 will begin to expand and deform. The ends of the pipes 82 inside the two groups of fixing tubes 81 are connected to the clamping blocks 83 inside the fixing tube 81, and the clamping blocks 83 are slidably connected to the interior of the fixing tube 81. Therefore, even if the soft fixing sleeve 6 is deformed, the end of the pipe 82 will not easily fall off from the inside of the fixing tube 81.

[0043] like Figure 11-14 As shown, fixing bolts 84 are provided at the upper and lower ends of each set of fixing tubes 81, and the fixing bolts 84 are fixedly connected to the fixing tubes 81, and each set of fixing bolts 84 is threadedly connected to a set of fixing nuts 85 through the heat insulation cotton 73. Therefore, when the airbag 76 needs to be replaced, it is only necessary to unscrew the fixing nuts 85 from the fixing bolts 84 to pull the fixing bolts 84 out of the heat insulation cotton 73, and then a new airbag 76 can be replaced. The air nozzle 86 is horizontally arranged inside the body 72, and the air outlet of the air nozzle 86 passes through the body 72 and is connected to the pipe 82. Therefore, the airflow flowing into the air nozzle 86 will flow into the interior of the pipe 82 through the air outlet of the air nozzle 86 and flow into the interior of the airbag 76 through the pipe 82. The air inlet of the air nozzle 86 passes through the body 72 and is arranged outside the body 72 and is connected to the micro air pump 34 of the electrical component 3 by an air guide tube. Therefore, when the micro air pump 34 is working, the compressed airflow will flow into the interior of the air nozzle 86 through the air guide tube.

[0044] The movement process of this embodiment is as follows: first, the second magic sticky soft fleece surface is torn off from the second magic sticky bristle surface on the main body 72 through the net bag 71, and then the prepared Chinese medicine bag is placed inside the net bag 71, and then the second magic sticky soft fleece surface is re-bonded to the second magic sticky bristle surface, and then the zipper 68 at the shoulder piece 63 and the back neck piece 61 is opened, the opening of the medicine bag placement area 67 is opened, and then the elastic band 68 is pulled open, and the pressing device connected to the medicine bag is placed under the elastic band 68 and ensure that the medicine bag inside the net bag 71 is close to the skin of the shoulders and cervical vertebrae, and then the elastic band 68 is loosened and ensured that the elastic band 68 is correctly pressed and fixed to the pressing device. After the opening of the medicine bag placement area 67 is sealed again by the zipper 68, the soft fixing sleeve 6 can be bonded to the backpack 1 through the first magic sticky bristle surface 5 on the back piece 62 and the first magic sticky soft fleece surface 4 on the backpack 1.

[0045] After ensuring that the soft fixing sleeve 6 has been bonded to the backpack 1, after manually electrically connecting the thermistor 75 of the clamping device to the battery 33 of the electrical component 3 and connecting the air nozzle 86 to the air duct of the micro air pump 34 of the electrical component 3, the wearer can carry the backpack 1, and then use the upper arm tightening strap 65 and the auxiliary tightening strap 66 at the bottom of the upper arm piece 64 to fix the soft fixing sleeve 6 on the wearer's body, and then turn on the micro air pump 34 to inflate the air bag 76 through the air nozzle 86 and the pipe 82 to make the air bag 76 expand and deform, and then turn on the heating film 74 so that it can apply heat to the shoulders and the back of the neck.

[0046] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model.
