A centrifugal fan is provided inside the second housing, and a filter screen is provided on the second housing. An air outlet is provided on the second housing, and both the filter screen and the air outlet are close to the centrifugal fan. The first housing and the second housing are rotatably connected, and a limit mechanism is installed at the connection between the first housing and the second housing. The two ends of the air duct are connected to the air outlet and the air inlet, respectively.

[0007] As a preferred embodiment, the air duct is a flexible hose.

[0008] As a preferred embodiment, the first housing cover is provided with a first cover plate, and a second spring is fixedly connected to the heat sink. The two ends of the second spring respectively contact the heat sink and the first cover plate. Both sides of the heat sink extend with limiting edges, and the limiting edges contact the edge of the mounting groove.

[0009] As a preferred embodiment, the second housing is provided with a second cover plate, the filter screen passes through the second cover plate, and the air outlet is located near the connection between the first housing and the second housing.

[0010] As a preferred embodiment, the first housing extends to a first upper connecting portion, the second housing extends to a first lower connecting portion, a female bolt is rotatably connected to the first upper connecting portion, and a male bolt is rotatably connected to the first lower connecting portion, the female bolt and the male bolt being engaged and connected.

[0011] As a preferred embodiment, a second upper connecting portion extends from the first housing, and a second lower connecting portion extends from the second housing. The limiting mechanism is rotatably connected to the second upper connecting portion, and the limiting mechanism is slidably connected to the second lower connecting portion.

[0012] As a preferred embodiment, a first ratchet is fixedly connected to the second upper connecting part, and the limiting mechanism includes a button and a second ratchet.

[0024] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0025] Please refer to Figures 1-4 .

[0026] The present invention discloses a detachable mobile phone heat dissipation device, comprising a first housing 1, a second housing 2, and a duct 3;

[0027] The first housing 1 has an installation groove 12, an air inlet 13 and an air outlet 14. The installation groove 12 is located between the air inlet 13 and the air outlet 14, and an air duct is formed between the air inlet 13 and the air outlet 14. A heat sink 121 is installed in the installation groove 12. In this embodiment, the heat sink 121 is preferably a heat sink fin. The fins of the heat sink 121 are located in the air duct and are parallel to the air duct.

[0028] Furthermore, the first housing 1 is covered with a first cover plate 11, which limits the heat sink 121 within the first housing 1. Four second springs 123 are fixedly connected to the heat sink 121. The two ends of the second springs 123 respectively contact the heat sink 121 and the first cover plate 11, and the second springs 123 push the heat sink 121 out of the first housing 1. Both sides of the heat sink 121 extend with limiting edges 122, which contact the edge of the mounting groove 12 to prevent the heat sink 121 from being completely pushed out of the first housing 1. When the mobile phone is placed on the first housing 1, the heat sink 121 is pressed against the mobile phone by the push of the second springs 123.

[0029] A lower gripper 15 extends from the first housing 1, and an upper gripper 16 is provided on the outer side of the first housing 1. Two sliding rods 161 are slidably connected to the first housing 1. The two sliding rods 161 are respectively close to the two sides of the heat sink 121. One end of the sliding rod 161 is inserted into the first housing 1, and a first spring 162 is sleeved on the outer side of the sliding rod 161. The two ends of the first spring 162 respectively abut against one end of the sliding rod 161 and the inner wall of the first housing 1. The sliding rod 161 is fixedly connected to the upper gripper 16. The upper gripper 16 and the lower gripper 15 are respectively located at the top and bottom of the mounting groove 12. When the mobile phone is placed between the upper gripper 16 and the lower gripper 15, the first spring 162 pushes the sliding rod 161 into the first housing 1, and the sliding rod 161 pulls the upper gripper 16 closer to the lower gripper 15, so that the upper gripper 16 and the lower gripper 15 clamp the mobile phone.

[0030] A first upper connecting portion 17 extends from the first housing 1, and a second upper connecting portion 18 extends from the first housing 1. An air inlet 13 is located between the first upper connecting portion 17 and the second upper connecting portion 18.

[0031] Please refer to Figure 5 .

[0032] The second housing 2 is covered by a second cover plate 21. A centrifugal fan 22 is installed inside the second housing 2. The second cover plate 21 confines the centrifugal fan 22 inside the second housing 2. A filter screen 211 is installed on the second housing 2, and the filter screen 211 passes through the second cover plate 21. An air outlet 23 is opened on the second housing 2. Both the filter screen 211 and the air outlet 23 are close to the centrifugal fan 22. The centrifugal fan 22 draws cold air from the outside of the second housing 2 through the filter screen 211. When the cold air passes through the filter screen 211, it filters the dust in the cold air to prevent dust from accumulating in the device. The centrifugal fan 22 pushes the cold air out from the air outlet 23.

[0033] The second housing 2 has a first lower connecting portion 24 extending from it, and a second lower connecting portion 25 extending from it. The air outlet 23 is located between the first upper connecting portion 17 and the second upper connecting portion 18.

[0034] Please refer to Figure 2 , Figure 5 and Figure 6 .

[0035] The first housing 1 is rotatably connected to the first lower connecting part 24 and the second lower connecting part 25 of the second housing 2 via the first upper connecting part 17 and the second upper connecting part 18, respectively. In this embodiment, the air guide 3 is preferably a flexible hose. When the first housing 1 rotates on the second housing 2, the flexible air guide 3 can deform by stretching or contracting to follow the rotation of the first housing 1, so that the air outlet 23 and the air inlet 13 can always be connected through the air guide 3. The two ends of the air guide 3 are connected to the air outlet 23 and the air inlet 13, respectively, so that the centrifugal fan 22 can push the cold air into the air duct through the air guide 3.

[0036] A female bolt 171 is rotatably connected to the first upper connecting part 17, and a male bolt 241 is rotatably connected to the first lower connecting part 24. The female bolt 171 and the male bolt 241 are connected in a mating manner. The first upper connecting part 17 is rotatably connected to the first lower connecting part 24 through the female bolt 171, so that the first housing 1 can rotate on the second housing 2 at a certain angle.

[0037] Please refer to Figure 2 and Figure 7 .

[0038] A limiting mechanism 4 is installed at the connection between the first housing 1 and the second housing 2. The limiting mechanism 4 is rotatably connected to the second upper connecting part 18 and slidably connected to the second lower connecting part 25.

[0039] Furthermore, a first ratchet 181 is fixedly connected to the second upper connecting part 18, and the limiting mechanism 4 includes a button 41 and a second ratchet 42; the button 41 is rotatably connected to the second upper connecting part 18, one end of the button 41 passes through the second upper connecting part 18, and a screw 411 is installed on the button 41; a central shaft 421 extends from the second ratchet 42, a slider is embedded on the outside of the central shaft 421, and a sliding groove is provided on the second lower connecting part 25, with the slider slidably connected to the sliding groove; a third spring 43 is sleeved on the outside of the central shaft 421, and the two ends of the third spring 43 respectively abut against the second ratchet 42 and the second lower connecting part 25; the screw 411 is fixedly connected to the second ratchet 42, and the second ratchet 42 is engaged with the first ratchet 181.

[0040] The third spring 43 pushes the second ratchet 42 to engage with the first ratchet 181. When the first housing 1 rotates and unfolds on the second housing 2, the inclined surface of the teeth on the first ratchet 181 slides on the inclined surface of the teeth on the second ratchet 42, allowing the first housing 1 to rotate and unfold into an acute angle on the second housing 2. The straight surface of the teeth on the first ratchet 181 engages with the straight surface of the teeth on the second ratchet 42, preventing the first housing 1 and the second housing 2 from merging, thus allowing the device to be used as a mobile phone holder. When the user wants to fold up the device, pressing the button 41 pushes the second ratchet 42 away from the first ratchet 181, releasing the second ratchet 42 from limiting the rotation of the first housing 1, thereby allowing the first housing 1 and the second housing 2 to be folded up and merged.

[0041] This utility model provides a detachable mobile phone heat dissipation device. The user can place the mobile phone between the upper and lower clamps. The first spring pushes the slide bar into the first housing, pulling the upper clamp closer to the lower clamp, so that the upper and lower clamps hold the mobile phone. By rotating the first housing to rotate the second housing, the limiting mechanism fixes the angle of the first housing after the second housing rotates, so that this device can be used as a mobile phone stand.

[0042] A centrifugal fan draws in cool air from the outside, and a filter filters the cool air entering the second housing. The centrifugal fan then injects the cool air into the first housing through a duct. When the upper and lower grippers hold the phone, the phone comes into contact with the heat sink and exchanges heat with it, transferring its own heat to the heat sink. As the cool air circulates in the air duct, it exchanges heat with the heat sink and is converted into hot air, cooling the heat sink. The hot air is then exhausted from the vent, thus cooling the phone.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
