Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a dust-proof and heat-dissipating power adapter. Background Art

[0002] A power adapter is a device that converts power to small portable electronic devices and appliances. It's commonly found in small electronic products like mobile phones, LCD monitors, and laptops. It typically consists of a housing, a power transformer, and a rectifier circuit. Its primary function is to convert alternating current (AC) into direct current (DC) suitable for electronic devices.

[0003] As described in the published patent with publication number CN221574352U, a dust-proof power adapter, in the prior art, when some power adapters are in use, a power interface is generally provided at one end for connecting a power plug, and an output plug is connected at the other end through a wire to connect the power adapter to a device that needs power supply. When the power adapter is not used for a long time, dust is usually easily accumulated at the power interface. When a lot of dust accumulates, it is not conducive to heat dissipation at the interface, thereby affecting the performance and life of the power adapter, and is not conducive to the normal use of the power adapter.

[0004] To sum up, in the prior art, when the current power adapter is not in use, dust easily accumulates inside the power interface due to the lack of dust-proof measures. This not only affects the appearance, but more importantly, it has an adverse effect on the function of the power adapter. For example, dust may cause the connection between the power adapter and the device to be unstable, affecting the transmission of current, and dust accumulation may affect the heat dissipation performance of the power adapter, causing the internal components to overheat, accelerating aging, and shortening the life of the device.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0007] To achieve the above object, the present invention provides the following technical solution: a dustproof and heat-dissipating power adapter, comprising a housing, a circuit board is provided in the inner cavity of the housing, and a power interface and a power cord are provided at both ends of the housing;

[0008] A notch is formed on a side of the shell near the power interface, a baffle is provided on the notch, a cavity is formed between the baffle and the shell, a through hole is opened at a position corresponding to the baffle and the power interface, a slidable dustproof plate is provided in the cavity formed by the baffle and the shell, a first arc-shaped groove is opened on the dustproof plate at a position facing a side of the shell and near the power interface, a curved clip that closely matches the first arc-shaped groove is provided on the side of the notch facing the dustproof plate, and a second arc-shaped groove is opened on the dustproof plate at a position facing a side of the shell and away from the power interface;

[0009] When the dustproof plate slides and covers the power interface, the second arc-shaped groove fits tightly with the arc-shaped clip.

[0010] As a further solution of the utility model: two heat absorbing plates are provided on the inner wall of the housing near the power line, the two heat absorbing plates are respectively located on both sides of the power line, a plurality of heat dissipation fins are provided on the heat absorbing plates, and two heat pipes connected to the heat absorbing plates are provided on the inner wall of the housing;

[0011] The housing is provided with two openings on a side facing the power line. The two openings correspond to the two heat absorbing plates respectively. A cooling fan is installed in the openings.

[0012] As a further solution of the present invention: magnetic parts are provided at both ends of the inner wall of the slot, and magnetic parts are provided on both sides of the dustproof plate.

[0013] As a further solution of the present invention: an operation notch is provided on one side of the through hole toward the dustproof plate.

[0014] As a further solution of the present invention: a plurality of anti-slip grooves are formed at positions of the dustproof plate corresponding to the positions of the operation notches.

[0015] As a further solution of the present invention: the arc-shaped clip is made of elastic silicone material.

[0016] As a further solution of the present invention: a dustproof net is provided on the outside of the heat dissipation fan.

[0017] As a further solution of the present invention: the heat conducting pipe is arranged in a serpentine structure.

[0018] Compared with the prior art, the beneficial effects of this technical solution are as follows: when the power adapter is not in use, the dustproof plate in the cavity between the baffle and the housing is slid toward the power interface, and the power interface is covered with the dustproof plate. Thus, when the power adapter is not in use, the power interface can be protected by the dustproof plate, which can prevent dust from accumulating inside the power interface after being placed for a long time, thereby preventing dust from affecting the transmission stability of the current and avoiding shortening the service life of the power adapter.

[0019] At the same time, when the dust shield is sliding, the first arc groove on the side of the housing disengages from the arc clip on the notch, and when the dust shield covers the power interface, the second arc groove and the arc clip fit tightly together, so that the position of the dust shield is restricted by the second arc groove and the arc clip and fixed, thereby preventing the dust shield from sliding into the cavity formed between the baffle and the housing when the power adapter is stored;

[0020] When the power adapter is in use, the heat generated by the internal circuit board is dissipated into the inside of the shell. At this time, the two heat pipes arranged on the inner wall of the shell absorb the heat and transfer the heat to the heat absorbing plate, and then the heat is dissipated by the heat dissipation fins. At the same time, when the cooling fan is used, the air inside the shell is quickly discharged to the outside and forms an airflow. While being discharged from the shell, the airflow takes away the heat dissipated by the heat dissipation fins, thereby achieving heat dissipation and cooling of the circuit board, reducing the working temperature of the circuit board to avoid damage caused by overheating.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-5 A dustproof and heat-dissipating power adapter includes a shell 1, a circuit board 2 is provided in the inner cavity of the shell 1, and a power interface 11 and a power line 12 are respectively provided at both ends of the shell 1;

[0032] A notch 13 is formed on one side of the housing 1 near the power interface 11, and a baffle 3 is provided on the notch 13. A cavity is formed between the baffle 3 and the housing 1, and a through hole 31 is opened at a position corresponding to the baffle 3 and the power interface 11. A slidable dustproof plate 4 is provided in the cavity formed by the baffle 3 and the housing 1. The dustproof plate 4 is provided with a first arc-shaped groove 41 at a position facing a side of the housing 1 and near the power interface 11. A curved clip 5 that closely matches the first arc-shaped groove 41 is provided on the side of the notch 13 facing the dustproof plate 4, and a second arc-shaped groove 42 is opened on the dustproof plate 4 at a position facing a side of the housing 1 and away from the power interface 11;

[0033] When the dustproof plate 4 slides and covers the power interface 11 , the second arc-shaped groove 42 is tightly matched with the arc-shaped clamping strip 5 .

[0034] Specifically, when the power adapter is not in use, the dustproof plate 4 in the cavity between the baffle 3 and the shell 1 is slid toward the power interface 11, and the power interface 11 is covered by the dustproof plate 4. At the same time, during the sliding process, the first arc groove 41 of the dustproof plate 4 facing the side of the shell 1 disengages from the arc clip 5 on the notch 13, and while the dustproof plate 4 covers the power interface 11, the second arc groove 42 fits tightly with the arc clip 5, so that the position of the dustproof plate 4 is restricted by the second arc groove 42 and the arc clip 5 and fixed, preventing the dustproof plate 4 from sliding into the cavity formed between the baffle 3 and the shell 1 during storage of the power adapter, so that the power interface 11 of the power adapter can be protected by the dustproof plate 4 when it is not in use, and dust can be prevented from accumulating inside the power interface 11 after being placed for a long time, thereby preventing dust from affecting the stability of current transmission and avoiding affecting the service life of the power adapter.

[0035] Among them, the arc-shaped clip 5 is made of elastic silicone material. When the dustproof plate 4 slides, the first arc-shaped groove 41 and the arc-shaped clip 5 made of silicone squeeze each other, causing the arc-shaped clip 5 to deform, and then the first arc-shaped groove 41 separates from the arc-shaped clip 5. While the dustproof plate 4 covers the power interface 11, the position of the second arc-shaped groove 42 moves to the position of the arc-shaped clip 5, and the arc-shaped clip 5 is tightly fitted and connected with the second arc-shaped groove 42, thereby fixing the position of the dustproof plate 4.

[0036] Preferably, magnetic elements 8 are provided at both ends of the inner wall of the slot 13 , and magnetic elements 43 are provided on both sides of the dustproof plate 4 .

[0037] When the dustproof plate 4 slides to cover the power interface 11, the magnetic member 43 provided on the side of the dustproof plate 4 facing the power interface 11 and the magnetic member 8 provided on the inner wall of the slot 13 close to the power interface 11 are attracted and fixed to each other, so that one side of the dustproof plate 4 is fixed by the magnetic member 43 and the magnetic member 8, and the other side is fixed by the second arc-shaped slot 42 and the arc-shaped clip 5, that is, a fixed structure is formed on both sides, thereby further limiting the position of the dustproof plate 4 and further preventing the dustproof plate 4 from moving on its own;

[0038] When the dustproof plate 4 does not need to cover the power interface 11, the magnetic part 43 set on the side of the dustproof plate 4 away from the power interface 11 and the magnetic part 8 set on the inner wall of the slot 13 away from the power interface 11 are adsorbed and fixed to each other, and the other side of the dustproof plate 4 is fixed by the first arc groove 41 and the arc clip 5, thereby fixing the position of the dustproof plate 4 to prevent the dustproof plate 4 from moving on its own and affecting the normal use of the power interface 11.

[0039] Furthermore, an operation notch 32 is extended from the through hole 31 toward one side of the dustproof plate 4 .

[0040] A plurality of anti-slip grooves 44 are formed at positions of the dustproof plate 4 corresponding to the operation notch 32 .

[0041] When the dustproof plate 4 needs to be slid to a position covering the power interface 11, the setting of the operating notch 32 can increase the size of the contact area between the operator and the dustproof plate 4. At the same time, an anti-slip groove 44 is set at the position corresponding to the dustproof plate 4 and the operating notch 32, which can further facilitate sliding the dustproof plate 4 toward the power interface 11 and reduce the difficulty of operation.

[0042] In the embodiment of the present utility model, two heat absorbing plates 6 are provided on the inner wall of the housing 1 near the power line 12. The two heat absorbing plates 6 are respectively located on both sides of the power line 12. A plurality of heat dissipation fins 61 are provided on the heat absorbing plates 6. Two heat pipes 62 connected to the heat absorbing plates 6 are provided on the inner wall of the housing 1.

[0043] The housing 1 has two openings on one side facing the power line 12 . The two openings correspond to the two heat absorbing plates 6 , respectively. Cooling fans 7 are installed in the openings.

[0044] Specifically, when the power adapter is in use, the heat generated by the internal circuit board 2 is dissipated into the interior of the housing 1. At this time, the two heat pipes 62 arranged on the inner wall of the housing 1 absorb the heat and transfer the heat to the heat absorption plate 6. The heat is then dissipated by the heat dissipation fins 61. When the power adapter is powered on, the cooling fans 7 installed in the two openings are started. When the cooling fans 7 are used, the air inside the housing 1 is quickly discharged to the outside and forms an airflow. The airflow takes away the heat dissipated by the heat dissipation fins 61 while being discharged from the housing 1, thereby achieving heat dissipation and cooling of the circuit board 2, reducing the operating temperature of the circuit board 2 to avoid damage caused by overheating;

[0045] A single chip microcomputer for controlling the cooling fan 7 may be provided on the circuit board. When the power interface 11 is connected to the power supply, the cooling fan 7 can start to perform cooling work.

[0046] A dustproof net 9 is provided on the outside of the cooling fan 7. The dustproof net 9 prevents dust from entering the inside of the shell 1 through the opening for installing the cooling fan 7 when the power adapter is not in use, causing dust accumulation inside the shell 1. The dustproof net 9 and the shell 1 can be connected by a detachable connection method such as screw connection, hinged connection or snap connection, which is not limited here.

[0047] The heat pipe 62 is arranged in a serpentine structure. By arranging the heat pipe 62 in a serpentine shape, the occupied area of ​​the heat pipe 62 on the inner wall of the shell 1 can be increased, so that more heat can be absorbed faster to improve the heat dissipation effect.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
