[0030] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in combination with the drawings and examples.

[0031] Please refer to Figures 1 to 5 The air nozzle assembly 10 provided by the embodiment of the present application will be described. The air nozzle assembly 10 comprises an air nozzle shell 11 and a air distribution plate 12.

[0032] The air nozzle shell 11 has a main air duct 111, the main air duct 111 penetrates the front end of the air nozzle shell 11 to form a main air outlet 112, and penetrates the rear end of the air nozzle shell 11 to form a main air inlet 113. The main air duct 111 is provided with the air distribution plate 12, the air distribution plate 12 separates the main air duct 111 into an auxiliary air duct 121, the rear end of the auxiliary air duct 121 is in communication connection with the main air duct 111, the cross-sectional area of the auxiliary air duct 121 is smaller than that of the main air duct 111; the bottom of the air nozzle shell 11 is provided with a negative pressure air duct 131, the rear end of the negative pressure air duct 131 is in communication connection with the outside, and the front end of the negative pressure air duct 131 is in communication connection with the front end of the auxiliary air duct 121 and forms a wind volume collection outlet 14.

[0033] During the use of the air nozzle assembly 10, the wind volume is input into the main air duct 111 through the blowing function of the hair styling device, most of the wind volume can be discharged from the main air duct 111 to the main air outlet 112; part of the wind volume is input into the auxiliary air duct 121, and the flow rate of this part of the wind volume is increased by the auxiliary air duct 121 which is smaller in size than the main air duct 111; when this part of the wind volume with increased flow rate is transported to the wind volume collection outlet 14, a negative pressure can be generated at the wind volume collection outlet 14 to drive the outside wind volume to enter from the negative pressure air duct 131 and the wind volume at the wind volume collection outlet 14 and the auxiliary air duct 121 are collected, so as to increase the wind volume and discharge it outward from the wind volume collection outlet 14.

[0034] Specifically, by setting the size of the auxiliary air duct 121 to be smaller than the main air duct 111, and forming the air volume collection outlet 14 at the front ends of the auxiliary air duct 121 and the negative pressure air duct 131; when the hot air enters the main air duct 111, most of the hot air can be discharged from the main air outlet 112 to blow towards the hair; the remaining part of the hot air enters the auxiliary air duct 121 and increases the flow rate through the auxiliary air duct 121, when the part of the hot air with increased flow rate flows to the air volume collection outlet 14, it will generate negative pressure at the air volume collection outlet 14 to bring in external air volume from the negative pressure air duct 131 and collect the air volume at the air volume collection outlet 14 and the auxiliary air duct 121; part of the hot air collects external cold air, which can reduce the temperature to blow towards the hair roots, to prevent the user from using the nozzle assembly 10 to blow the hair and causing hot air to scald the scalp, thereby improving the safety performance; and part of the hot air collects external cold air, which not only increases the flow rate but also increases the air volume, which can achieve the effect of quick-drying blowing.

[0035] It should be noted that the size of the auxiliary air duct is smaller than the size of the main air duct, which can be that the cross-sectional area of the auxiliary air duct is smaller than the cross-sectional area of the main air duct; or the volumetric flow rate of the auxiliary air duct is smaller than the volumetric flow rate of the main air duct; or the diameter of the auxiliary air duct is smaller than the diameter of the main air duct.

[0036] It can be understood that when the nozzle assembly 10 inputs normal temperature air volume or cold air volume, the air volume of the air volume collection outlet 14 can be increased through the nozzle assembly 10, and different blowing effects can be achieved by making the air volume of the main air outlet 112 different from the air volume of the air volume collection outlet 14.

[0037] In some embodiments of the present application, the auxiliary air duct 121 is provided with an auxiliary air outlet 122 at the front end, and the auxiliary air outlet 122 is smaller than the main air outlet 112. The auxiliary air duct 121 is provided with an auxiliary air inlet 123 at the rear end, and the auxiliary air inlet 123 is larger than the auxiliary air outlet 122, the auxiliary air inlet 123 is smaller than the main air outlet 112, and the main air outlet 112 is smaller than the main air inlet 113. With such a structure, the ability of the auxiliary air duct 121 to increase the flow rate of the air volume can be further improved, so that the air volume collection outlet 14 can reliably form a negative pressure area, thereby ensuring that the negative pressure area can reliably suck in external gas.

[0038] It should be noted that in the structure of the auxiliary air duct 121 being smaller than the main air duct 111, the flow rate of the air volume of the auxiliary air duct 121 is greater than the flow rate of the air volume of the main air duct 111, so the structure of the auxiliary air duct 121 being smaller than the main air duct 111 can be used alone. In addition, the structure of the auxiliary air duct 121 being smaller than the main air duct 111 and the structure of the auxiliary air outlet 122 being smaller than the main air outlet 112 can also be used in combination.

[0039] Specifically, the air distribution plate 12 is arranged close to the bottom wall of the main air duct 111, and the left and right ends of the air distribution plate 12 correspond to abut against the two sides of the main air duct 111; the bottom side of the air distribution plate 12 facing the main air inlet 113 is provided with a first inclined surface 124, and the first inclined surface 124 and the bottom wall of the main air duct 111 form a horn-shaped auxiliary air duct 121 with the front end being larger than the rear end.

[0040] More specifically, the first free end 1201 of the air distribution plate 12 extends to the end of the main air outlet 112 and protrudes from the front side of the main air outlet 112, and the second free end 1202 of the air distribution plate 12 extends backward; the front surface of the first free end 1201 of the air distribution plate 12 is provided with a plurality of comb teeth 125, which are arranged at intervals from left to right, and the comb teeth 125 are used for combing hair and dispersing air volume, which can assist the user in the blow-drying operation, thereby reducing the difficulty of the user in blow-drying and styling.

[0041] Preferably, the second free end 1202 extends to the center of the main air duct 111, but is arranged at intervals before and after the main air inlet 113, which can ensure that most of the air volume flows from the main air duct 111 to the main air outlet 112 after the main air inlet 113 inputs the air volume, and only part of the air volume flows into the auxiliary air duct 121 and increases the flow rate of the air volume through the auxiliary air duct 121.

[0042] Further, the top of the air distribution plate 12 is provided with a plurality of partitions 115, which are arranged at intervals left and right, and the top of each partition 115 extends upward and abuts against the top wall of the main air duct 111, so that the wind noise of the main air duct 111 can be reduced, and the air flow of the main air duct 111 can be more stable and less likely to occur turbulence.

[0043] In some other embodiments of the present application, the bottom of the air nozzle shell 11 is provided with an extension shell 13, the extension shell 13 and the bottom of the air nozzle shell 11 form a negative pressure air duct 131, and the front end of the negative pressure air duct 131 is a negative pressure outlet 132; the bottom wall of the air nozzle shell 11 is retracted backward to form an avoiding gap 114, and the auxiliary air outlet 122 and the negative pressure outlet 132 are connected in communication through the avoiding gap 114 and form an air volume collection outlet 14.

[0044] Specifically, the rear end of the negative pressure air duct 131 is a negative pressure inlet 133, which is connected in communication with the outside, so that the outside air can enter the negative pressure air duct 131 through the negative pressure inlet 133. The negative pressure inlet 133 is larger than the negative pressure outlet 132, and the negative pressure outlet 132 is larger than the auxiliary air outlet 122; in this way, the negative pressure of the air volume collection outlet 14 can be enhanced, thereby ensuring that the work of sucking the outside gas into the negative pressure air duct 131 can be reliably performed.

[0045] Some embodiments of the present application also provide a hair treatment device, which can be a hair dryer or a hair comb, etc.

[0046] Specifically, the main air inlet 113 is circular in cross section, and the inner wall of the main air inlet 113 is provided with a plurality of buckling protrusions 1131 arranged in an annular array. The air nozzle assembly 10 is detachably assembled with the hair treatment device by matching the buckling protrusions 1131 with the buckling grooves of the hair treatment device.

[0047] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is specifically described. These descriptions are only for explaining the principle of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanation herein, any modification, equivalent replacement and improvement within the spirit and principle of the present application, and other specific embodiments of the present application that can be conceived by those skilled in the art without creative labor, shall be included in the protection scope of the present application.
