Problems solved by technology

However, in this solution, since the separation surface radially penetrates the inner space of the tuyere, it will have a blocking effect on the wind, resulting in wind resistance and loss of air volume; how to increase the flow rate of the air blown through the tuyere and minimize the pressure loss needs to be solved question

Embodiment 1

[0043] Such as figure 1 , 2 As shown, a tuyere 1 for a hair dryer includes an outer cylinder 101; the outer cylinder 101 has an air inlet 102 for receiving air flow from the hair dryer;

[0044] an air outlet 103 for releasing the air flow;

[0045] And the installation part 104 that cooperates with the hair dryer;

[0046] Wherein, the outer cylinder 101 is provided with a plurality of partition plates 105 extending along the radial direction of the outer cylinder 101, and the inner space of the outer cylinder 101 is divided into a central air duct 107 and a plurality of main air ducts by the partition plates 105. The multiple main air ducts 106 are arranged around the central air duct 107; The central air duct 107 and the main air duct 106 may or may not be connected. In this example, there are three main air ducts 106 . It can be understood that the number of main air ducts 106 is two, four, five and so on.

[0047] Further, such as figure 2 , image 3 , Figure 4...

Embodiment 2

[0064] The difference between this embodiment and Embodiment 1 is that, if Figure 6 , 7 As shown, the central air duct 107 is isolated from the main air duct 106, the end of the partition plate 105 away from the side wall of the outer tube 101 has an extension 110, and the extensions 110 of a plurality of partition plates 105 are spliced ​​together to define the central air duct 107 .

[0065] In this example, the extension part 110 is an arc-shaped plate, and a plurality of arc-shaped plates are spliced ​​together to define a tapered central air duct 107 , and the central air duct 107 is not connected to the main air duct 106 . That is to say, the main air duct 106 and the central air duct 107 are not connected in space, and the airflow received by the tuyere 1 splits into the main air duct 106 and the central air duct 107, and then blows out from the outlets of the air ducts independently. It can be understood that the end of the partition plate 105 away from the side wal...

Embodiment 3

[0067] The difference between this embodiment and Embodiment 2 is that, as Figure 8 As shown, the central air duct 107 is isolated from the main air duct 106, and the end of the partition plate 105 away from the side wall of the outer tube 101 has an extension 110, and the extensions 110 of a plurality of partition plates 105 are spliced ​​together to define the central air duct 107 The extension part 110 is provided with a plurality of through holes 111 through which the main air duct 106 and the central air duct 107 communicate.

Abstract

The invention relates to the field of household electrical appliances. In order to avoid the problems of hot spots and colloidal sol phenomena caused by excessively high airflow temperature in the center of the tuyere, and the problem that the tuyere is easy to lose, it particularly relates to a tuyere for a hair dryer, including an outer cylinder; The cylinder has an air inlet for receiving the air flow from the hair dryer; an air outlet for releasing the air flow; and a mounting part that is mated and connected with the hair dryer; The partition plate extending in the direction, the inner space of the outer cylinder is divided into a central air duct and a plurality of inner air ducts by the partition plate, and the plurality of inner air ducts are arranged around the central air duct; the air nozzle receives air from the hair dryer The air flow is divided into the central air duct and the inner air duct. The advantage is to reduce wind resistance, increase wind speed and reduce pressure loss.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an air nozzle for a hair dryer and the hair dryer. Background technique [0002] At present, most of the air nozzles used in conjunction with hair dryers on the market are single air ducts; a few air nozzles with multiple air ducts have their internal space divided into multiple separate ducts by the dividing surface extending along the center line of the air nozzle. The principle of this structure is to increase the wind speed by reducing the cross-sectional area to promote the dispersion of wet hair, thereby increasing the contact surface area of ​​the hair to dry the hair quickly. However, in this solution, since the separation surface radially penetrates the inner space of the tuyere, it will block the wind, generate wind resistance, and cause loss of air volume; how to increase the flow rate of the airflow blown through the tuyere and minimize the pressure loss needs to b...
