Description

Technical Field

[0001] This invention relates to the field of backpack technology, specifically a backpack with a cooling plate for heat dissipation. Background Technology

[0002] When people go out, they often pack essentials in their backpacks, especially when traveling or hiking. They might also pack snacks or drinking water. With more and more young people choosing backpacking, the added weight of these items increases the backpack's weight. Furthermore, the close contact between the backpack and the user's back prevents heat dissipation and causes sweating, increasing discomfort. A cooling backpack, on the other hand, is a specially designed backpack designed to provide ventilation in the back area, helping to keep the back cool and comfortable.

[0003] Existing technologies, such as patent document CN215503692U, disclose a cooling device and backpack, including a water storage bag and a water pump. The water storage bag and the water pump are connected by a water pipe, which includes an inlet pipe and an outlet pipe. The water storage bag has an inlet and an outlet, and contains ice water. One end of the inlet pipe is connected to the water pump, and the other end is connected to the inlet. One end of the outlet pipe is connected to the water pump, and the other end is connected to the outlet. This patent document achieves a cooling effect by placing a water storage bag and a water pump in clothing or a backpack, adding ice water to the water storage bag, and then circulating the ice water through the water pump.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the water circulation pipes of existing heat dissipation backpacks are fixed to the backpack, making them difficult to disassemble, inconvenient to install and use with different backpacks, and have a small coverage area and poor heat dissipation effect, thus reducing the practicality of heat dissipation backpacks.

[0005] Therefore, we propose a cooling pad heat dissipation backpack. Summary of the Invention

[0006] The purpose of this invention is to provide a cooling pad heat dissipation backpack to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling pad heat dissipation backpack, comprising a first cloth bag, a second cloth bag, and a cooling pad, wherein a condenser is fixedly connected to the surface of the cooling pad, a connector is fixedly connected to the surface of the cooling pad, a magnetic buckle is fixedly connected to the surface of the first cloth bag, both the first and second cloth bags are made of ventilated fabric, a ventilated mesh is fixedly connected to the surface of the second cloth bag, the cooling pad has a multi-segment curved structure, and further includes:

[0008] A fixing device is provided on the inner wall of the first and second cloth bags to fix the cooling chip. The fixing device includes several rubber blocks fixedly connected to the inner wall of the first cloth bag and pointed protrusions for fixing the cooling chip.

[0009] An adjustment device is provided on the surface of the second cloth bag for adjusting the distance between the second cloth bag and the user. The adjustment device includes a folding piece fixedly connected to the surface of the second cloth bag, a first support rod, a second support rod, and a third support rod for adjusting the distance between the second cloth bag and the user.

[0010] A protective device is provided on the surface of the first and second cloth bags to protect the user's arm joints. The protective device includes tape glued to the surface of the second cloth bag and a sponge pad for protecting the user's arm joints.

[0011] The aforementioned components achieve the following effects: By incorporating a fixing device, the heat dissipation effect of the cooling backpack is improved. This addresses the issue of the water circulation pipes being fixed to the backpack, making disassembly difficult and inconvenient for use with different backpacks. The multi-segment curved design of the cooling element increases its coverage area and heat dissipation effect, further enhancing the backpack's practicality. The adjustment device improves airflow around the user's back, reducing the risk of sweating due to close contact between the user and the backpack, thus further improving the backpack's performance. The protective device enhances user protection, reducing the risk of the user's arms being in close contact with the second fabric bag, which could interfere with the cooling element's operation, further improving the backpack's practicality.

[0012] Preferably, the fixing device further includes four first Velcro straps, which are respectively fixedly connected to the first cloth bag and the second cloth bag. The pointed protrusion is fixedly connected to the cooling element, and the pointed protrusion has a conical structure and is evenly distributed at the bending part of the cooling element.

[0013] The above components achieve the following effects: First, select a suitable backpack. Then, sew magnetic snaps onto the backpack. Next, attach the first fabric bag to the backpack. The magnetic snaps on the first fabric bag and the backpack are magnetically attracted to each other, thus improving the stability of the first fabric bag and facilitating its use with different backpacks. Then, place the cooling element inside the first fabric bag and attach it to the rubber block. The pointed protrusion will insert into the rubber block, thus improving the stability of the cooling element and reducing the problem of shaking. This facilitates the disassembly and installation of the cooling element. Next, attach the second fabric bag to the first Velcro strap inside the first fabric bag, which initially improves the connection between the first and second fabric bags. The cooling element is then installed on the backpack using the first and second fabric bags. Connect the connector to an external power source (power bank or battery, etc.) to facilitate the operation of the cooling element.

[0014] Preferably, the pointed surface is fixedly connected with a plurality of protrusions, and the protrusions are spherical structures.

[0015] The effect achieved by the above components is that the protrusion can further increase the friction between the tip and the rubber block, thereby improving the stability of the tip.

[0016] Preferably, the inner wall of the first cloth bag is fixedly connected to two fixed frames, and the surface of the fixed frames is slidably connected to an insert rod. The insert rod is U-shaped, and the surface of the fixed frames has two insertion holes. The insert rod engages with the insertion holes on the surface of the fixed frames.

[0017] The above components achieve the following effect: when the insert rod inside the fixing frame is pulled, the condenser on the cooling plate is located inside the fixing frame. Pushing the insert rod into the fixing frame fixes the condenser, thus reducing the problem that the cooling plate may fall off when shaken due to the high weight of the condenser itself. The fixing frame has two sets, which can fix the condenser and the connector, thereby improving the overall stability of the cooling plate.

[0018] Preferably, a first spring is fixedly connected to the surface of the insertion rod, and one end of the first spring is fixedly connected to the fixing frame.

[0019] The effect achieved by the above components is that the insertion rod will be stably inserted into the fixed frame under the action of the first spring tension, further improving the stability of the insertion rod.

[0020] Preferably, the surfaces of the first bag and the second bag are fixedly connected with a second Velcro fastener, and the second Velcro fastener has the same shape as the first bag and the second bag.

[0021] The effect achieved by the above components is that when the second Velcro straps on the first and second bags are pressed, the second Velcro straps can effectively improve the stability between the first and second bags.

[0022] Preferably, the adjusting device further includes a second spring, the two ends of which are fixedly connected to the first support rod and the second support rod respectively. The first support rod is fixedly connected to the folding piece, the second support rod is slidably connected to the first support rod, and the third support rod is slidably connected to the second support rod. A third spring is fixedly connected to the side of the second support rod and the third support rod that are close to each other. The end of the third support rod away from the first support rod is fixedly connected to the folding piece. The folding piece is connected through the arc surfaces of the first support rod, the second support rod, and the third support rod.

[0023] The aforementioned components achieve the following effects: When a user wears the backpack, their back comes into contact with the folding plate. At this time, the folding plate folds to different degrees according to the weight of the backpack, creating a gap between the user's back and the backpack. This reduces the problem of the user's back sweating more easily due to close contact with the backpack. The backpack will bounce slightly as the user walks. The elastic force of the second and third springs will push the second and third support rods, enhancing the bounce effect of the backpack. At this time, the folding plate reciprocates under the compression of the backpack and the elastic force of the second and third springs, causing air to circulate on the user's back and improving the heat dissipation effect between the backpack and the user's back.

[0024] Preferably, a baffle is fixedly connected to the surface of the folded piece, and the baffle is a rubber plate.

[0025] The effect achieved by the above components is that the baffle can effectively reduce the discomfort caused by the user's back being squeezed when the folding plate bounces.

[0026] Preferably, the protective device further includes a groove formed on the surface of the sponge pad, the sponge pad is placed on the surface of the second cloth bag, and the tape is fixedly connected to the sponge pad.

[0027] The above-mentioned components achieve the following effects: the movable sponge pad comes into contact with the second cloth bag, and the sponge pad is initially fixed with tape. The groove allows the sponge pad to bend along with the first and second cloth bags, reducing the risk of damage to the sponge pad. At this time, the sponge pad can protect the user's arm.

[0028] Preferably, a connecting rope is fixedly connected to the surface of the sponge pad, and the connecting rope is an elastic rope.

[0029] The above components achieve the following effect: First, pull the connecting rope and put it on the first and second cloth bags. Then, release the connecting rope. The tension of the connecting rope will cause the sponge pad to come into contact with the first and second cloth bags, further improving the stability of the sponge pad.

Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figure 1-12 This invention provides a technical solution: a cooling pad heat dissipation backpack, comprising a first cloth bag 1, a second cloth bag 2, and a cooling pad 3. A condenser 4 is fixedly connected to the surface of the cooling pad 3, and a connector 9 is fixedly connected to the surface of the cooling pad 3. A magnetic buckle 8 is fixedly connected to the surface of the first cloth bag 1. Both the first cloth bag 1 and the second cloth bag 2 are made of ventilated fabric, and a ventilated mesh is fixedly connected to the surface of the second cloth bag 2. The cooling pad 3 has a multi-segment curved structure. The backpack also includes a fixing device 5 disposed on the inner wall of the first cloth bag 1 and the second cloth bag 2 for fixing the cooling pad 3. The fixing device 5 includes several rubber blocks 5 fixedly connected to the inner wall of the first cloth bag 1. 1. A pointed protrusion 52 for fixing the cooling element 3; an adjustment device 6 disposed on the surface of the second cloth bag 2 for adjusting the distance between the second cloth bag 2 and the user, the adjustment device 6 including a folding piece 61 fixedly connected to the surface of the second cloth bag 2, a first support rod 62, a second support rod 63 and a third support rod 64 for adjusting the distance between the second cloth bag 2 and the user; a protective device 7 disposed on the surfaces of the first cloth bag 1 and the second cloth bag 2 for protecting the user's arm joint, the protective device 7 including an adhesive tape 73 glued to the surface of the second cloth bag 2 and a sponge pad 71 for protecting the user's arm joint.

[0049] The following section will describe in detail the specific settings and functions of its fixing device 5, adjusting device 6, and protective device 7.

[0050] like Figures 1-8As shown, by setting the fixing device 5, the heat dissipation effect of the heat dissipation backpack is improved, and the problem of the water circulation pipe of the heat dissipation backpack being fixed to the backpack, making it difficult to disassemble and inconvenient to install and use with different backpacks is reduced. The cooling plate 3 is set in a multi-segment curved shape, which facilitates the improvement of the coverage area and heat dissipation effect of the cooling plate 3, further improving the practicality of the heat dissipation backpack. By setting the adjustment device 6, the airflow effect at the user's back is improved, reducing the problem of the user's back sweating due to close contact with the backpack, further improving the use effect of the heat dissipation backpack. By setting the protective device 7, the protection effect for the user is improved, reducing the problem of the user's arms being in close contact with the second cloth bag 2 when wearing the backpack, which affects the operation of the cooling plate 3, further improving the practicality of the heat dissipation backpack. The fixing device 5 also includes four first Velcro straps 57, which are fixedly connected to the first cloth bag 1 and the second cloth bag 2 respectively. The pointed protrusions 52 are fixedly connected to the cooling plate 3. The pointed protrusions 52 are conical structures and are evenly distributed at the curved parts of the cooling plate 3. First, select a suitable backpack. Then, sew magnetic snaps 8 onto the backpack. Next, attach the first cloth bag 1 to the backpack. The magnetic snaps 8 connect the first cloth bag 1 to the backpack, improving its stability and making it compatible with different backpacks. Place the cooling element 3 inside the first cloth bag 1 and attach it to the rubber block 51. The pointed protrusion 52 will insert into the rubber block 51, further improving the stability of the cooling element 3 and reducing its wobbling. This facilitates the disassembly and installation of the cooling element 3. Next, attach the second cloth bag 2 to the first Velcro strap 57 inside the first cloth bag 1, initially improving the connection between the two. The cooling element 3 is then mounted on the backpack using the first and second cloth bags. Connect the connector 9 to an external power source (power bank or battery, etc.) to enable the cooling element 3 to operate. Several protrusions 53, each with a spherical structure, are fixedly connected to the surface of the pointed protrusion 52. At this point, the protrusion 53 further increases the friction between the pointed protrusion 52 and the rubber block 51, improving the stability of the pointed protrusion 52. Two fixing frames 54 are fixedly connected to the inner wall of the first cloth bag 1. Insert rods 55 are slidably connected to the surface of the fixing frames 54. The insert rods 55 are U-shaped, and two insertion holes are opened on the surface of the fixing frames 54. The insert rods 55 engage with the insertion holes on the surface of the fixing frames 54. Pulling the insert rods 55 inside the fixing frames 54 causes the condenser 4 on the cooling plate 3 to be located inside the fixing frames 54. Pushing the insert rods 55 into the fixing frames 54 fixes the condenser 4, reducing the problem of the cooling plate 3 easily falling off due to the high weight of the condenser 4. Two sets of fixing frames 54 are provided to fix the condenser 4 and the connector 9, thereby improving the overall stability of the cooling plate 3. A first spring 56 is fixedly connected to the surface of the insert rods 55, and one end of the first spring 56 is fixedly connected to the fixing frames 54.The insertion rod 55 is stably inserted into the fixing frame 54 under the tension of the first spring 56, further improving the stability of the insertion rod 55. The surfaces of both the first cloth bag 1 and the second cloth bag 2 are fixedly connected with second Velcro 58, which have the same shape as the first cloth bag 1 and the second cloth bag 2. Pressing the second Velcro 58 on the first cloth bag 1 and the second cloth bag 2 effectively improves the stability between them.

[0051] like Figure 3 and Figure 9 as well as Figure 10 As shown, the adjusting device 6 also includes a second spring 65. The two ends of the second spring 65 are fixedly connected to the first support rod 62 and the second support rod 63, respectively. The first support rod 62 is fixedly connected to the folding piece 61. The second support rod 63 is slidably connected to the first support rod 62. The third support rod 64 is slidably connected to the second support rod 63. A third spring 66 is fixedly connected to the side of the second support rod 63 and the third support rod 64 that are close to each other. The end of the third support rod 64 away from the first support rod 62 is fixedly connected to the folding piece 61. The folding piece 61 is connected through the arc surfaces of the first support rod 62, the second support rod 63 and the third support rod 64. When a user wears the backpack, their back comes into contact with the folding plate 61. The folding plate 61 folds to varying degrees depending on the weight of the backpack, creating a gap between the user's back and the backpack. This reduces close contact and prevents the user's back from sweating. The backpack bounces slightly with the user's movement. The elasticity of the second spring 65 and the third spring 66 pushes the second support rod 63 and the third support rod 64, enhancing the backpack's bounce. The folding plate 61 reciprocates under the pressure of the backpack and the elasticity of the second and third springs 65 and 66, promoting airflow around the user's back and improving heat dissipation. A baffle 67, made of rubber, is fixedly connected to the surface of the folding plate 61. The baffle 67 effectively reduces discomfort caused by pressure on the user's back when the folding plate 61 bounces.

[0052] like Figure 3 and Figure 11 as well as Figure 12As shown, the protective device 7 also includes a groove 72, which is formed on the surface of the sponge pad 71. The sponge pad 71 is placed on the surface of the second cloth bag 2, and the tape 73 is fixedly connected to the sponge pad 71. The sponge pad 71 is moved to contact the second cloth bag 2, and the tape 73 is used for initial fixation. The groove 72 allows the sponge pad 71 to bend along with the first cloth bag 1 and the second cloth bag 2, reducing the risk of damage. At this time, the sponge pad 71 can protect the user's arms. A connecting rope 74, which is an elastic rope, is fixedly connected to the surface of the sponge pad 71. First, the connecting rope 74 is pulled open and looped onto the first cloth bag 1 and the second cloth bag 2. Then, the connecting rope 74 is released, and the tension of the connecting rope 74 causes the sponge pad 71 to adhere to the first cloth bag 1 and the second cloth bag 2, further improving the stability of the sponge pad 71.

[0053] Working principle: When using the cooling backpack, first select a suitable backpack, then sew the magnetic snap 8 onto the backpack. Next, attach the first cloth bag 1 to the backpack. The magnetic snap 8 connects the first cloth bag 1 to the backpack, improving its stability and facilitating its use with different backpacks. Then, place the cooling element 3 inside the first cloth bag 1 and attach it to the rubber block 51. The pointed protrusion 52 will insert into the rubber block 51, further improving the stability of the cooling element 3 and reducing its wobbling. This design addresses the issue of movement, facilitating the disassembly and installation of the cooling chip 3. The protrusion 53 further increases the friction between the pointed protrusion 52 and the rubber block 51, improving the stability of the pointed protrusion 52. Pulling the insertion rod 55 within the fixing frame 54 causes the first spring 56 to extend along with the insertion rod 55. At this point, the condenser 4 on the cooling chip 3 is positioned within the fixing frame 54. Pushing the insertion rod 55 into the fixing frame 54 secures the condenser 4, reducing the risk of the cooling chip 3 falling off due to the condenser 4's high weight. Under the tension of the first spring 56, the tube is stably inserted into the fixing frame 54, further improving the stability of the insertion rod 55. The fixing frame 54 has two sets, which can fix the condenser 4 and the connector 9, thereby improving the overall stability of the cooling plate 3. At this time, the first Velcro 57 in the second cloth bag 2 and the first cloth bag 1 are attached to each other, which initially improves the connection effect between the first cloth bag 1 and the second cloth bag 2. At this time, the second Velcro 58 on the first cloth bag 1 and the second cloth bag 2 is pressed, which can effectively improve the stability between the first cloth bag 1 and the second cloth bag 2. At this time, the cooling plate 3 is installed on the backpack with the help of the first cloth bag 1 and the second cloth bag 2. The connector 9 is connected to an external power source (power bank or battery, etc.), which makes it convenient for the cooling plate 3 to work. By setting the fixing device 5, the heat dissipation effect of the heat dissipation backpack is improved, and the problem that the water circulation pipe of the heat dissipation backpack is fixed on the backpack and difficult to disassemble is reduced, which makes it inconvenient to install and use with different backpacks. The cooling plate 3 is set to a multi-segment curved shape, which facilitates the improvement of the coverage area and heat dissipation effect of the cooling plate 3, further improving the practicality of the heat dissipation backpack.

[0054] When a user wears the backpack, their back comes into contact with the folding plate 61. The folding plate 61 folds to varying degrees depending on the weight of the backpack, creating a gap between the user's back and the backpack. This reduces the risk of the user's back sweating due to close contact. The backpack bounces slightly as the user moves, and the elasticity of the second spring 65 and the third spring 66 pushes the second support rod 63 and the third support rod 64, enhancing the backpack's bounce. The folding plate 61 reciprocates under the pressure of the backpack and the elasticity of the second and third springs 65 and 66, promoting airflow around the user's back and improving heat dissipation. The baffle 67 effectively reduces discomfort caused by pressure on the user's back when the folding plate 61 bounces. By incorporating the adjustment device 6, airflow around the user's back is improved, reducing close contact and sweating, further enhancing the effectiveness of the heat-dissipating backpack.

[0055] First, pull the connecting rope 74. At this time, the sponge pad 71 is moved to contact the second cloth bag 2. The sponge pad 71 is initially fixed with tape 73. The groove 72 allows the sponge pad 71 to bend with the first cloth bag 1 and the second cloth bag 2, reducing the risk of damage to the sponge pad 71. Then, release the connecting rope 74. The tension of the connecting rope 74 will cause the sponge pad 71 to come into contact with the first cloth bag 1 and the second cloth bag 2, further improving the stability of the sponge pad 71. At this time, the sponge pad 71 can protect the user's arms. By setting up the protective device 7, the protection effect on the user is improved, reducing the problem of the user's arms coming into close contact with the second cloth bag 2 when wearing the backpack, which would affect the operation of the cooling chip 3, and further improving the practicality of the heat dissipation backpack.
