Description

Technical Field

[0001] This utility model relates to the field of hair dryers, specifically to a hair dryer housing with high-efficiency heat dissipation. Background Technology

[0002] Hair dryers, as a common household appliance, primarily function by using a motor to drive a fan, which then blows air over a heating element to produce hot air. During this process, both the heating element and the motor generate heat. Traditional hair dryer casings have limitations in heat dissipation. As hair dryer wattage increases and usage time grows, if the heat cannot be dissipated effectively, it can lead to a series of problems.

[0003] Common hair dryer casings are mostly made of ordinary plastic. While this is inexpensive and easy to manufacture, prolonged high-power use can easily lead to overheating of the internal motor, affecting its lifespan. Furthermore, traditional hair dryer casings lack effective airflow guidance. Without designs like the ventilation holes on the first square cavity and mounting plate surface, airflow inside the hair dryer is obstructed, failing to create a good heat dissipation channel. Heat cannot be quickly transferred to the outside, thus affecting heat dissipation efficiency. Additionally, traditional hair dryer casings, once locked, make it difficult to inspect internal components and are inconvenient to disassemble. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned defects and provide a hair dryer housing with high-efficiency heat dissipation. When the hair dryer is in use, the heat dissipation fins increase the heat dissipation area, which can effectively dissipate heat from the first square cavity, thus solving the technical problem that the internal motor is prone to overheating under long-term high-power use in the prior art.

[0005] The objective of this utility model is achieved through the following means:

[0006] The high-efficiency heat dissipation hair dryer housing includes an assembly housing consisting of two pieces, left and right, which are assembled by a snap-fit ​​structure on the inner side of the assembly housing. The upper inner side of each assembly housing is provided with a first square cavity, and the top of each assembly housing is provided with a second square cavity. An assembly plate is inserted into the first square cavity, and a cover plate is inserted into the second square cavity. The assembly plate has heat dissipation holes inside, and heat dissipation fins are welded to the inner side of each assembly plate. Hinge ears are installed on the upper, lower, left, and right sides of the first square cavity, and limit levers are installed on the outer side of each hinge ear via a damping pivot.

[0007] Furthermore, the number of heat dissipation holes is 10-20 sets, and the interior of each heat dissipation hole is lined with a dustproof mesh. The number of heat dissipation fins is 4-8 sets, which improves the heat dissipation speed.

[0008] Furthermore, limiting corner brackets are installed at the four corners of the inner cavity of the first square cavity, and magnets are laid on the outer side of each limiting corner bracket. Iron sheets are laid at the four inner corners of the assembly plate corresponding to the limiting corner brackets. The added limiting corner brackets make it more convenient to insert the assembly plate.

[0009] Furthermore, slots are provided on both the left and right sides of the second square cavity, and mounting blocks are installed on both sides of the top of the cover plate. The interior of the mounting blocks is hollow, which facilitates assembly.

[0010] Furthermore, each mounting block has a pressure block inserted inside, and each pressure block has a guide rod connected to both sides of its inner end. The inner ends of the guide rods penetrate through the corresponding positions of the mounting blocks, and springs are fitted on the outer sides of the guide rods at positions between the pressure block and the inner cavity of the mounting block.

[0011] Furthermore, through slots are provided at corresponding positions on the bottom of the mounting block and inside the cover plate. Connecting blocks are inserted into the through slots. The top of the connecting blocks is connected to the bottom of the pressure block. Insert plates are welded to the bottom of the connecting blocks. By pressing the pressure block, the connecting blocks and insert plates can be moved, thereby enabling the insert plates to cooperate with the slots, which facilitates the disassembly and assembly of the cover plate.

[0012] The beneficial effects of this invention are as follows: The added first square cavity allows the assembly plate and heat dissipation fins to be inserted. The assembly plate is then limited by a limiting angle bracket and a limiting lever. This increases the heat dissipation area through the heat dissipation fins during use, effectively dissipating heat and improving heat dissipation efficiency. Furthermore, the heat dissipation holes on the surface of the first square cavity and the assembly plate promote airflow, forming a good heat dissipation channel that allows heat to be quickly transferred to the outside, maintaining a stable internal temperature and preventing safety issues caused by high internal temperatures during use. Secondly, the added second square cavity allows for the removal and installation of the cover plate, further improving heat dissipation speed. After the cover plate and assembly plate are removed, the first and second square cavities together form a three-way connection on the surface of the hair dryer casing, facilitating the inspection and maintenance of internal components and making it easier to pry open the two assembly shells for insertion into the hair dryer casing.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In this embodiment, refer to Figure 1 - Figure 4 The specific implementation of the assembly housing 1 consists of two pieces, left and right, which are assembled through a snap-fit ​​structure on the inner side of the assembly housing 1.

[0020] Please see Figure 1 Each assembly housing 1 has a first square cavity 2 installed on its upper inner side, and a second square cavity 3 installed on its top. An assembly plate 4 is inserted into the first square cavity 2. Please refer to [link / reference]. Figure 2 The second square cavity 3 is fitted with a cover plate 9, the assembly plate 4 is fitted with heat dissipation holes 5, and heat dissipation fins 6 are welded to the inner side of the assembly plate 4. The first square cavity 2 is fitted with hinge ears 7 on the upper, lower and left and right sides, and the hinge ears 7 are fitted with limit levers 8 on the outer side of the hinge ears 7 through damping shafts.

[0021] The number of heat dissipation holes 5 is 10-20 sets, and the interior of each heat dissipation hole 5 is lined with a dustproof mesh. The number of heat dissipation fins 6 is 4-8 sets. Each of the four corners of the inner cavity of the first square cavity 2 is equipped with a limiting angle code 21, and the outer side of the limiting angle code 21 is lined with a magnet. The four corners of the inner side of the assembly plate 4 are lined with iron plates at positions corresponding to the limiting angle code 21. By adding the first square cavity 2, the assembly plate 4 and the heat dissipation fins 6 can be inserted into it. The assembly plate 4 is then limited by the limiting angle code 21 and the limiting lever 8. When the hair dryer is in use, the heat dissipation area is increased by the heat dissipation fins 6, which can effectively dissipate heat and improve heat dissipation efficiency. In addition, the heat dissipation holes 5 opened on the surface of the first square cavity 2 and the assembly plate 4 promote air flow and form a good heat dissipation channel, so that heat can be quickly transferred to the outside, keeping the internal temperature of the hair dryer stable and avoiding safety problems caused by the high internal temperature of the hair dryer during use.

[0022] Please see Figure 3 The second square cavity 3 has slots 10 on both the left and right sides, please refer to [reference needed]. Figure 4Mounting blocks 11 are installed on both sides of the top of the cover plate 9. The interior of each mounting block 11 is hollow, and a pressure block 12 is inserted inside each mounting block 11. Guide rods 13 are connected to both sides of the inner end of each pressure block 12, with the inner ends of the guide rods 13 penetrating the corresponding positions of the mounting blocks 11. Springs 14 are fitted onto the outer sides of the guide rods 13 between the pressure block 12 and the inner cavity of the mounting block 11. Through slots 15 are opened at the bottom of the mounting blocks 11 and at corresponding positions inside the cover plate 9, and each through slot 15 is filled with a [missing information - likely a type of object]. The top of the connecting block 16 is connected to the bottom of the pressure block 12. The bottom of the connecting block 16 is welded with the insertion plate 17. The added second square cavity 3 can disassemble and install the cover plate 9, which further improves the heat dissipation speed. After the cover plate 9 and the assembly plate 4 are removed, the first square cavity 2 and the second square cavity 3 together form a three-way state on the surface of the hair dryer housing. This not only facilitates the inspection and maintenance of internal components, but also makes it easy to pry open the two assembly shells 1, which is convenient for inserting the hair dryer housing.

[0023] This design incorporates a first square cavity 2, allowing the assembly plate 4 and heat dissipation fins 6 to be inserted. The assembly plate 4 is then positioned using a limiting angle bracket 21 and a limiting lever 8. This increases the heat dissipation area of ​​the heat dissipation fins 6 during use, effectively dissipating heat and improving heat dissipation efficiency. Furthermore, the heat dissipation holes 5 on the surfaces of the first square cavity 2 and the assembly plate 4 promote airflow, creating a good heat dissipation channel that allows heat to be quickly transferred to the outside, maintaining a stable internal temperature and preventing safety issues caused by high internal temperatures during use. The added second square cavity 3 allows for the removal and installation of the cover plate 9, further enhancing heat dissipation speed. After the cover plate 9 and assembly plate 4 are removed, the first and second square cavities 2 and 3 together form a three-way connection on the surface of the hair dryer casing, facilitating the inspection and maintenance of internal components and allowing for easy separation of the two assembly shells 1 for insertion into the hair dryer casing.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
