[0014] In a preferred embodiment, a heat-insulating cavity is formed between the air duct member and the outer shell, and heat-dissipating holes are provided on the outer shell, and the heat-dissipating holes are communicated with the heat-insulating cavity.

[0015] In a preferred embodiment, the heat dissipation holes include a first heat dissipation hole located on the first shell and a second heat dissipation hole located on the second shell.

[0016] In a preferred embodiment, a guide portion recessed toward the inner cavity is provided in the middle of the air guide cover, and an arc-shaped guide surface is formed on a side of the air guide portion facing the air duct.

[0018] In a preferred embodiment, there are multiple air outlets, the multiple air outlets are arranged in a ring shape, and the multiple air outlets are arranged around the guide part.

[0019] Compared with the prior art, this application has at least the following technical effects:

[0020] 1. The connector assembly of the hair dryer of the present application comprises a shell, a connector, a duct member and a guide cover, wherein the shell comprises a first shell and a second shell which are perpendicular to each other, the duct member is installed in the second shell, the connector is installed in the first shell, the duct member comprises a guide member, the guide member has a trumpet-shaped inner cavity, the cavity wall of the inner cavity encloses to form an air duct, the air duct takes in air along a first direction and discharges air along a second direction, and the air inlet and outlet directions can be vertical, meeting the requirement of lateral air discharge of a straight-line hair dryer. Moreover, since the air duct is a trumpet-shaped one which gradually widens along the second direction, that is, along the air discharge direction, the air duct gradually widens, the air discharge becomes smoother, thereby reducing the noise during the use of the hair dryer and improving the user experience.

[0021] 2. In order to further reduce the noise during the use of the hair dryer, in a preferred embodiment of the present application, a guide column extending along the second direction is arranged in the air duct, and the air flow inlet of the air duct is directly opposite to the outer wall of the guide column. In this way, the airflow entering the air duct preferentially collides with the guide column, and is diverted under the action of the outer wall of the guide column, and then flows along the air duct. Since the wall of the inner cavity is horn-shaped, the airflow gradually diffuses along the flow direction of the airflow, the airflow flows smoothly, the noise is low, and the air volume loss is reduced.

[0022] 3. In order to make the air flow more smoothly, in a preferred embodiment of the present application, the connector is extended into the first shell, and the air flow outlet of the connector is connected to the air flow inlet of the air duct. With this arrangement, the air flow discharged from the connector can directly go to the air duct without being lost. On the one hand, the wind speed of the air flow at the air duct outlet can be increased, and on the other hand, the air flow can be prevented from dissipating and transferring heat to the outer shell, thereby preventing the outer shell from overheating and scalding the user.

[0023] 4. Furthermore, the air guide member is provided with sealing ribs or sealing grooves at the air flow inlet and the air flow outlet respectively, and the air guide cover or the connecting head is provided with matching sealing ribs or sealing grooves. The double stop design can effectively prevent the air flow from overflowing, and prevent the shell from overheating and scalding the user due to the air flow overflow, thereby improving the safety of the hair dryer.

[0024] 5. An insulation cavity is provided between the air duct and the shell, and there are heat dissipation holes on the shell that are connected to the insulation cavity. The provision of the insulation cavity can effectively prevent the heat of the air duct from being transferred to the shell, and can reduce the temperature of the shell. At the same time, since there are heat dissipation holes on the shell, the airflow at the air outlet during the use of the hair dryer will drive the airflow at the heat dissipation holes, so part of the airflow can enter the insulation cavity through the heat dissipation holes, which can reduce the temperature of the insulation cavity, so that the temperature of the shell will not be overheated, and the user will not be burned.

[0025] 6. By providing a guide portion recessed toward the inner cavity in the middle of the guide cover, and forming an arc-shaped guide surface on one side of the guide portion facing the air duct, the airflow in the air duct is guided, so that the airflow transition is smoother and the noise is further reduced. By providing multiple air outlets, the multiple air outlets are arranged in a ring shape, and the multiple air outlets are arranged around the periphery of the guide portion, when the airflow flows through the guide portion, the guide surface can guide the airflow to be discharged toward the air outlet, thereby improving the air outlet efficiency and the user experience.

[0038] In order to solve the problem that the connector assembly of the straight hair dryer in the prior art makes a lot of noise during use, the present application provides a connector assembly for a hair dryer, such as Figure 1-4 As shown, the connector assembly of the hair dryer includes a housing 3, a connector 4, an air duct member 2 and a guide cover 1.

[0039] The housing 3 includes a cylindrical first shell 31 and a cylindrical second shell 32. The tail end of the first shell 31 is connected to the head end of the second shell 32. The first shell 31 extends along a first direction, and the second shell 32 extends along a second direction. The first direction and the second direction are perpendicular to each other.

[0040] The connector 4 is cylindrical and connected to the head end of the first shell 31 . The connector 4 is used to connect to the airflow outlet of the hair dryer. The airflow generated by the hair dryer flows to the joint assembly via the connector 4 .

[0041] The duct member 2 is arranged inside the second shell 32, and the duct member 2 includes a flow guide member 22 with an inner cavity. The cavity wall of the inner cavity encloses a duct, that is, the cavity wall of the inner cavity forms a duct wall, and the duct extends along the second direction. The air flow inlet of the duct is arranged near the rear end of the first shell 31, and the duct takes in air along the first direction. The air flow outlet of the duct is arranged near the rear end of the second shell 32, and the duct discharges air along the second direction. Since the first direction and the second direction are perpendicular, that is, the air inlet direction and the air outlet direction of the duct are perpendicular, the use of the joint assembly of the present application can achieve vertical air intake and horizontal air outlet, meeting the use requirements of a straight-line hair dryer.

[0042] The air guide cover 1 is disposed at the air flow outlet of the air duct member 2 , and an air outlet 11 is disposed on the air guide cover 1 .

[0043] During use of the hair dryer of the present application, the airflow generated by the hair dryer enters the connector assembly through the air inlet 41 on the connecting head 4, and the airflow flows through the air inlet 41 and the air duct in the air duct member 2 in turn, and is discharged from the air outlet 11 of the air guide cover 1. The airflow can be guided by the air duct in the air duct member 2 to achieve the effect of vertical air intake and lateral air outlet, which is compatible with the use of a straight-line hair dryer.

[0044] It can be understood that, in the present application, the housing 3 includes a first shell 31 and a second shell 32 , and the first shell 31 and the second shell 32 can be integrally formed, or the first shell 31 and the second shell 32 can be separately connected.

[0045] It can be understood that, in the present application, the first direction is vertical and the second direction is horizontal. The first shell 31 extends along the first direction, that is, the first shell 31 extends vertically, and the second shell 32 extends along the second direction, that is, the second shell 32 extends horizontally. In the present application, the air duct extends horizontally, and the air duct enters vertically and exhausts horizontally.

[0046] In order to reduce the noise of the hair dryer during use, in the present application, the cavity wall of the inner cavity of the guide member 22 is in the shape of a trumpet that gradually widens along the second direction. With this arrangement, the airflow gradually diffuses along the second direction (that is, the air outlet direction), and the flow of the airflow becomes smoother, which can effectively reduce the noise of the airflow flow process and improve the use effect of the hair dryer.

[0047] In order to further reduce the noise of the hair dryer during use, in the present application, the duct member 2 also includes a guide column 21 arranged in the inner cavity of the guide member 22, and the guide column 21 extends along the second direction. An air duct is formed between the cavity wall of the inner cavity of the guide member 22 and the outer peripheral wall of the guide column 21. The air flow inlet of the air duct is directly opposite to the outer peripheral wall of the guide column 21. With such an arrangement, the air flow entering the air duct will first hit the outer peripheral wall of the air guide column, and after being diverted to the left and right by the outer peripheral wall of the air guide, the air flow will flow along the cavity wall of the inner cavity toward the air flow outlet of the air duct, making the air flow smoother and reducing the wind noise to a certain extent.

[0048] It can be understood that in the present application, since the cavity wall of the inner cavity of the guide member 22 is in the shape of a trumpet, the cross-section of the cavity wall of the inner cavity of the guide member 22 is circular, and the guide house 21 is arranged at the center of the inner cavity. With such an arrangement, the flow velocity of the airflow is the same when the airflow flow distance is the same along the flow direction of the airflow, which can further ensure the uniformity of the air outlet of the air duct and reduce noise.

[0049] In the present application, the connector 4 extends into the first housing 31, and the airflow outlet of the connector 4 is connected to the airflow inlet of the duct member 2. That is, the head end of the connector 4 is used to connect to the airflow outlet of the hair dryer, and the tail end of the connector 4 is connected to the airflow inlet of the duct member 2. With this arrangement, the airflow discharged from the hair dryer can directly enter the duct member 2 under the guidance of the connector 4, which can effectively prevent the airflow from overflowing between the duct member 2 and the housing 3, and prevent the housing 3 from overheating, thereby improving the user's safety.

[0050] In order to prevent air flow from overflowing, in the present application, a first sealing rib 42 is provided at the air flow outlet of the connector 4, and a first sealing groove 222 is provided at the air flow inlet of the air duct of the air guide member 22. When the connector 4 is installed with the first shell 31, the first sealing rib 42 is inserted into the first sealing groove 222. The cooperation between the first sealing rib 42 and the first sealing groove 222 can effectively prevent the air flow from overflowing from the connection between the connector 4 and the air duct member 2. On the one hand, the air volume of the air flow in the air duct member 2 is guaranteed, and on the other hand, overheating of the outer shell 3 caused by air flow overflow can be avoided.

[0051] In the present application, the air deflector 1 is arranged at the air flow outlet of the air duct member 2, and the air deflector 1 is provided with an air outlet 11, and the air outlet 11 is connected to the air duct. In order to make the airflow be discharged from the air outlet 11 in a concentrated manner, the air deflector 1 is provided with a second sealing rib 122, and the air deflector rib is provided with a second sealing groove 223 at the air flow outlet of the air duct. When the air deflector 1 is installed on the second shell 32, the cooperation of the second sealing rib 122 and the second sealing groove 223 can effectively prevent the airflow from overflowing from the connection between the air deflector 1 and the air duct member 2, and can ensure that the airflow is discharged from the air outlet 11 in a concentrated manner.

[0052] In a preferred embodiment of the present application, a plurality of air outlets 11 are provided, and the plurality of air outlets 11 are arranged in a ring shape on the air deflector 1. The plurality of annular air outlets 11 can ensure uniform discharge of the airflow, increase the air outlet area of ​​the joint assembly, and thus improve the hair drying efficiency of the hair dryer. Specifically, a guide portion 12 that is recessed into the inner cavity of the air guide member 22 is provided in the middle of the air deflector 1, and an arc-shaped guide surface 121 is formed on the side of the air deflector 12 facing the air duct, and the plurality of air outlets 11 are arranged around the outer periphery of the air deflector 12. In this arrangement, when the airflow flows through the air deflector 12, the guide surface 121 can guide the airflow to be discharged from the air outlet 11, thereby improving the air outlet efficiency and the user's experience. In addition, in order to improve the installation reliability of the air deflector 1, the air deflector 12 is preferably connected to the guide column 21, which can be screwed, clamped, riveted, etc., and the connection method is not limited.

[0053] Furthermore, in order to reduce the temperature of the connector assembly during the use of the hair dryer, in the present application, a heat-insulating cavity is formed between the air duct member 2 and the housing 3, and a heat-dissipating hole connected to the heat-insulating cavity is provided on the housing 3. In this way, the heat-insulating cavity can effectively prevent the heat of the air duct member 2 from being transferred to the housing 3, thereby reducing the temperature of the housing 3. At the same time, since the housing 3 is provided with heat-dissipating holes, the airflow at the air outlet 11 during the use of the hair dryer will drive the airflow at the heat-dissipating holes, so part of the airflow can enter the heat-insulating cavity through the heat-dissipating holes, thereby reducing the temperature of the heat-insulating cavity, preventing the temperature of the housing 3 from overheating, and preventing the user from being scalded. In a preferred embodiment of the present application, the heat-dissipating holes include a first heat-dissipating hole 51 provided on the first housing 31 and a second heat-dissipating hole 52 provided on the second housing 32.
