Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a flow channel isolation collar and a hair dryer. Background Technology

[0002] During use, hair dryers generate unnecessary heat from their electronic components. When this heat is concentrated on the electronic components, it can easily damage them and shorten their lifespan.

[0003] In existing designs, to make efficient use of the space inside the hair dryer, the circuit board is usually placed in the handle. If the heat dissipation channel is designed directly inside the handle and connected to the main airflow channel, this design method in the current technology makes it difficult to create a sufficiently large negative pressure at the outlet of the heat dissipation channel, resulting in a small airflow through the heat dissipation channel and poor heat dissipation.

[0004] How to effectively dissipate heat from the circuit board and its electronic components in the handle is one of the important problems that urgently need to be solved in this field. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of this utility model more apparent, exemplary embodiments according to this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein.

[0044] Example 1

[0045] Please refer to Figures 1 to 3 This embodiment proposes a flow channel isolation collar, which includes an annular housing 1 and an isolation part 2; the annular housing 1 is used to provide support and facilitate connection with the blower body, and the isolation part 2 is used to form an isolation groove 21 so as to form sufficient negative pressure in the isolation groove 21 to ensure sufficient airflow into the isolation groove 21 through the connecting hole 11.

[0046] Specifically, the isolation part 2 is disposed inside the annular housing 1, and the isolation part 2 cooperates with the inner wall of the annular housing 1 to form an isolation groove 21 with one side opening; in implementation, the annular housing 1 is cylindrical, the isolation part 2 is formed on the inner wall of the annular housing 1, and the isolation groove 21 is open at only one end. During installation, the open end of the isolation groove 21 faces the fan and is located on the negative pressure side of the fan.

[0047] The annular housing 1 is provided with a connecting hole 11, which communicates with the isolation groove 21. The connecting hole 11 is used to communicate with the inside of the handle so that airflow can enter the isolation groove 21 from the handle through the connecting hole 11.

[0048] A portion of the inner wall of the annular shell 1 and the isolation section 2 form a main channel 3; the main channel 3 is the channel for most of the airflow, so that a large amount of airflow can be blown out through the main channel 3 by the fan.

[0049] The isolation groove 21 connects with the connecting hole 11 to form a secondary channel 4. The secondary channel 4 connects with the space inside the handle, allowing airflow entering through the handle to enter the secondary channel 4. The presence of the isolation groove 21, especially during installation, ensures that the opening of the isolation groove 21 faces the fan and is located on the negative pressure side of the fan, thus guaranteeing a sufficiently high negative pressure within the isolation groove 21. This, in turn, increases the airflow through the handle, ensuring effective heat dissipation. Especially at low speeds, it also helps dissipate heat from the electronic components inside the handle.

[0050] In practical implementation, to ensure negative pressure within the isolation groove 21, it is necessary to ensure that the isolation groove 21, except for its opening, is not directly connected to the main channel 3; in particular, it is essential to ensure that there are no openings at the bottom of the groove. Furthermore, the isolation section 2 should extend towards the fan; the closer the opening of the isolation groove 21 is to the negative pressure side of the fan, the easier it is to avoid generating greater negative pressure, and the airflow in the main channel 3 will be less likely to enter the isolation groove 21. In one implementation, a sealing ring 12 is formed at one end of the annular housing 1; an inner baffle ring 13 is formed on the sealing ring 12, located within the annular housing 1, and together with the isolation section 2, forms the main channel 3. The design of the inner baffle ring 13 primarily serves to cooperate with other components of the blower to keep the main channel 3 straight, thereby preventing turbulence when the airflow passes through and ensuring minimal resistance.

[0051] To create sufficient negative pressure within the isolation groove 21, the dimension of the isolation portion 2 along the axial direction of the annular housing 1 is not less than the length of the inner retaining ring 13. Considering both sealing and the need to create sufficient negative pressure, in a preferred embodiment, the dimension of the isolation portion 2 along the axial direction of the annular housing 1 is equal to the length of the inner retaining ring 13; that is, the opening of the isolation groove 21 is flush with the end face of the inner retaining ring 13.

[0052] Preferably, to further ensure sufficient negative pressure within the isolation groove 21, a rectifier mesh 5 is also included. The rectifier mesh 5 is installed inside the annular housing 1 and abuts against the open end of the isolation groove 21. In a specific implementation, the thickness of the rectifier mesh 5 is 0.5 to 5 mm. Covering the opening of the isolation groove 21 with the rectifier mesh 5 further prevents gas from the main channel 3 from entering the isolation groove 21, thereby ensuring negative pressure within the isolation groove 21 and allowing more airflow to flow in through the channel inside the handle.

[0053] Preferably, the center line of the mesh openings of the rectifying mesh 5 is aligned with the axial direction of the annular housing 1. This allows the airflow to enter in a straight line, which is beneficial for the fan to generate greater wind power.

[0054] In some implementations, in order to ensure sufficient airflow through the handle, there are multiple isolation sections 2, which are evenly distributed around the center line of the annular housing 1.

[0055] Example 2

[0056] This embodiment is a specific application of embodiment 1. The similarities will not be repeated. Only the differences will be explained below.

[0057] Please refer to Figures 4 to 6This embodiment proposes a hair dryer, which includes a handle 6 and a hair dryer body 7; in this embodiment, the hair dryer body 7 refers to the part of the hair dryer other than the handle 6.

[0058] The blower body 7 is provided with a flow channel isolation collar as described in Embodiment 1; specifically, the flow channel isolation collar is disposed inside the blower body 7 to separate the airflow of the main channel 3 and the secondary channel 4, so as to ensure that sufficient negative pressure is formed in the isolation groove 21, so that more air enters the blower from the secondary channel 4.

[0059] Specifically, one end of the handle 6 is connected to the hair dryer body 7; the handle 6 contains electronic components and an air inlet channel 61 is formed inside the handle 6; the far end of the handle 6 is connected to the hair dryer body 7, and the air inlet channel 61 is connected to the secondary channel 4; the end of the handle 6 away from the hair dryer body 7 is provided with an air inlet 62.

[0060] Please refer to Figure 6 With the above structure, two air channels are formed on the hair dryer: most of the air enters the fan through the main channel 3 from one end of the hair dryer body 7, and is discharged after being driven by the fan, as shown by the dotted arrow in the figure; a small part of the air enters the air inlet channel 61 inside the handle through the air inlet 62, and then enters the isolation groove 21 through the connecting hole 11, and then enters the fan after passing through the isolation groove 21, and is discharged after being driven by the fan, as shown by the solid arrow in the figure.

[0061] To connect the air inlet channel 61 with the connecting hole 11, the blower body 7 also includes an inner housing 71 and an outer housing 72. The inner housing 71 is a cylindrical shape with openings at both ends; one end of the inner housing 71 is sealed and installed inside the annular housing 1; a blower 73 is installed inside the inner housing 71; the main channel 3 and the isolation groove 21 are both connected to the inner hole of the inner housing 71; the outer housing 72 is fitted onto the inner housing 71, and an air passage connecting the air inlet channel 61 and the connecting hole 11 is formed between the outer housing 72 and the inner housing 71. Thus, air in the air inlet channel 61 is drawn into the space between the inner housing 71 and the outer housing 72 under negative pressure, and then enters the isolation groove 21.

[0062] Please refer to Figure 6 , Figure 6The outer shell 72 is not shown in the diagram. In a specific implementation, the annular shell 1 is disposed inside the outer shell 72, and the annular shell 1 and the outer shell 72 are sealed together. The inner shell 71 has a larger diameter at the end away from the annular shell 1. The end of the inner shell 71 away from the annular shell 1 is sealed together with the inner wall of the outer shell 72. When there are multiple isolation sections 2, each isolation groove 21 communicates with the air passage between the inner shell 71 and the outer shell 72. In some implementations, the air passage between the inner shell 71 and the outer shell 72 is annular.

[0063] To further reduce the air intake resistance of the air inlet 62, the centerline of the air inlet 62 is aligned with the length direction of the handle 6.

[0064] In order to ensure the negative pressure effect in the isolation groove 21, and to allow more air to flow in through the air inlet channel 61 inside the handle 6, the flow channel isolation collar is located on the negative pressure side of the fan 73.
