[0033] refer to Figures 1 to 8 The present application provides a functional head 100 of a hair dryer 1000, which is used to be combined with a main body 200 of the hair dryer 1000 to form the hair dryer 1000. The main body 200 of the hair dryer 1000 has an airflow traction component 210 and a heating component 220. The airflow traction component 210 is a high-speed fan or an air pump, which is used to draw the external airflow into the main body 200 and discharge it from the air outlet end 230 after passing through the heating component 220. The heating component 220 is an electric heating sheet or a heating wire. When the functional head 100 is installed on the main body 200 of the hair dryer 1000, the airflow channel 12 inside the functional head 100 is connected to the air outlet end 230 of the main body 200.

[0034] Specifically, Figures 2 to 5As shown, in the embodiment of the present application, the functional head 100 includes: an outer shell 20, an air guide shell 10 and a connecting seat 30, the outer shell 20 is hollow, the air guide shell 10 is constructed in the outer shell 20, and one end of the air guide shell 10 is provided with an air inlet 11, and the other end is provided with an air outlet 13, and an air flow channel 12 is formed between the air inlet 11 and the air outlet 13; the outer shell 20 is sleeved on the outside of the air guide shell 10, and the inner wall of the outer shell 20 is convexly provided with a support plate 21, the support plate 21 is abutted against the end face of the air guide shell 10 provided with the air inlet 11, so as to support the air guide shell 10, and the support plate 21 is provided with an avoidance notch 211 corresponding to the air inlet end of the air guide shell 10, and the avoidance notch 211 is correspondingly connected to the air inlet 11. The support plate 21 is in contact with the outer wall of the air guide shell 10 to limit the position, so that the outer shell 20 is spaced apart from most of the outer wall of the air guide shell 10 to form a heat dissipation space 25. At the same time, the support plate 21 is used to limit the position, so as to prevent the air guide shell 10 from being displaced under the impact of the high-speed airflow of the hair dryer 1000 host 200. The middle part of the connecting seat 30 is provided with an air port 31, and the upper end of the connecting seat 30 is concentrically provided with a first connecting panel 32 and a second connecting panel 33 surrounding the first connecting panel 32 and spaced apart. The first connecting panel 32 is sleeved on the shell wall where the air inlet 11 of the air guide shell 10 is located, and the second connecting panel 33 is sleeved on the inner wall of the outer shell 20 at the position outside the air inlet 11. Thus, the air guide shell 10 is fixed in the outer shell 20. The lower end of the connecting seat 30 is used to connect to the air outlet 230 of the main unit 200 , and the air outlet 31 connects the air path between the air outlet 230 and the air inlet 11 , thereby guiding the airflow of the air outlet section of the main unit 200 into the air flow channel 12 inside the air guide shell 10 .

[0035] Here, if Figures 1 to 4 Combination Figure 8 As shown, in the embodiment of the present application, the first connecting panel 32 and the second connecting panel 33 are protruded from the connecting seat 30 at intervals, so as to connect the air guide shell 10 and the outer shell 20, and a gap is provided between the outer shell 20 and the air guide, so as to avoid direct large-area contact between the air guide shell 10 and the outer shell 20, resulting in a high temperature of the outer shell 20 and a burning and stinging sensation when accidentally touched.

[0036] Specifically, Figure 1 Combination Figures 2 to 4As shown, in the embodiment of the present application, the host 200 is provided with a connection sink 240, the outer diameter of the housing 20 is adapted to the outer diameter of the host 200, and the outer diameter of the lower end of the connection seat 30 is smaller than the outer diameter of the housing 20, so as to be plugged into the connection sink 240. Here, in the embodiment of the present application, the outer diameter of the lower end of the connection seat 30 is smaller than the outer diameter of the housing 20, so when it is plugged into the connection sink 240 provided in the host 200, the outer wall of the connection seat 30 is wrapped by the connection sink 240 and will not be exposed to the outside world. Thereby, the phenomenon of scalding the user is avoided.

[0037] Specifically, Figure 4 As shown, in order to further reduce the contact area between the connection seat 30 and the air guide seat and reduce heat conductivity, in this embodiment, the shell 20 is further provided with a third connection panel 22 around the avoidance notch 211, and one of the first connection panel 32 and the third connection panel 22 is provided with an interference rib 221, and the interference rib 221 is used for interference engagement with the other of the two. There are multiple interference ribs 221, and multiple interference ribs 221 are arranged at intervals on the inner wall of the air guide shell 10 or the outer wall of the connection seat 30, and arranged along the circumferential direction thereof. Through the connection mode of multiple interference ribs 221, the contact area is effectively reduced, thereby reducing heat conduction.

[0038] It can be understood that in actual application, it is not limited to the above-mentioned embodiments. The method of providing an interference rib 221 on one of the first connecting panel 32 and the third connecting panel 22 is adopted. For example, in another embodiment of the present application, one of the first connecting panel 32 and the air guide shell 10 is provided with an interference rib 221, and the interference rib 221 is used to be interfered with with the other of the two, so as to reduce the heat conduction area. The method also falls within the scope of protection of the present application.

[0039] Specifically, Figure 2 Combination Figure 4 and Figure 8 As shown, the first connecting enclosure 32 includes a large diameter section 321 and a small diameter section 322, and a stop portion 323 is formed at the difference between the large diameter section 321 and the small diameter section 322. When the first connecting enclosure 32 is sleeved on the shell wall where the air inlet 11 of the air guide shell 10 is located, the end face of the third connecting enclosure 22 abuts against the stop portion 323, thereby preventing the first connecting enclosure 32 and the third connecting enclosure 22 from being connected through the interference rib 221, which causes air leakage due to the existence of an interference gap.

[0040] Specifically, Figure 3 , Figure 4 Combination Figure 7As shown, in the embodiment of the present application, in order to further ensure air tightness, in the embodiment of the present application, the shell wall where the air inlet 11 of the air guide shell 10 is located is in the shape of a countersunk hole, and when the first connecting enclosure 32 is sleeved on the inner side of the shell wall where the air inlet 11 of the air guide shell 10 is located, the end face of the small diameter section 322 of the first connecting enclosure 32 abuts against the step face 14 of the countersunk hole, and the end face 15 where the air inlet of the air guide shell 10 is located abuts against the support plate 21. That is, the step face of the countersunk hole of the air guide shell 10 abuts against the first connecting enclosure 32 for sealing, and the end face of the air inlet 11 of the air guide shell 10 abuts against the support plate 21 for sealing, the side wall of the countersunk hole is interference-sealed with the first connecting enclosure 32, the inner wall of the third connecting enclosure 22 is connected to the outer wall of the first connecting enclosure 32 through the interference convex ridge 221, and the end face of the third connecting enclosure 22 abuts against the stopper 323 for sealing. By adopting a multi-point sealing method, the sealing performance is further enhanced, and the precision of positioning and installation can be improved, thereby preventing the connecting seat 30 from being excessively inserted into the air guide shell 10, which would cause deformation and air leakage of the air guide shell 10.

[0041] Specifically, Figure 5 Combination Figure 6 , Figure 7 As shown, in the embodiment of the present application, the insertion end face of the first connecting enclosure 32 is a first wedge-shaped surface 324, and the countersunk step surface of the air guide shell 10 is a first inclined surface 16 corresponding thereto; and the end face of the air guide shell 10 having the air inlet 11 is a second wedge-shaped surface 17, and the surface of the support plate 21 corresponding to the support is a second inclined surface 212 corresponding to the wedge-shaped surface. By cooperating with the wedge-shaped surface and the inclined surface, the sealing performance is further enhanced, and the insertion guide is facilitated.

[0042] Specifically, Figure 2 Combination Figure 3 to Figure 4 As shown, in the embodiment of the present application, the air guide shell 10 is provided with an end face of the air inlet 11 located on the inner side of the end face of the lower end opening of the outer shell 20, so that the outer shell 20 completely covers the outer wall of the air guide shell 10 to prevent the outer wall of the air guide shell 10 from being exposed to the outside and accidentally touched; the height of the second connecting enclosure 33 is lower than the height of the first connecting enclosure 33, so that the interference position of the first connecting enclosure 32 and the air guide shell 10 is offset relative to the interference position of the second connecting enclosure 33 and the outer shell 20. Therefore, when inserting, the first connecting enclosure 32 is first inserted into the air guide shell 10 with interference resistance, and when it is further inserted into the second connecting enclosure 33 and the inner wall of the lower end opening of the outer shell 20, the interference resistance is further increased, thereby facilitating the identification of the interference sealing effects at the two places, and preventing the first connecting enclosure 32 and the second connecting enclosure 33 from generating interference force at the same time, resulting in a gap in one of them, and the sealing effect is poor and cannot be identified. Furthermore, the heat concentration positions where the connection base 30 is connected to the air guide shell 10 and the connection base 30 is connected to the outer shell 20 can be staggered, so as to further prevent the phenomenon of scalding caused by heat concentration.

[0043] Specifically, Figure 3 Combination Figure 4 As shown, in the embodiment of the present application, the side wall of the connecting seat 30 is also protruding with a sealing edge 34, the lower end opening of the outer shell 20 is in the shape of a countersunk hole, the outer peripheral surface of the sealing edge 34 is interference connected with the side wall of the countersunk hole, and the end face of the sealing edge 34 abuts against the countersunk hole-shaped step surface 23, thereby further preventing the leakage of air flow from the inner wall.

[0044] Specifically, Figure 6 Combination Figure 8 As shown, in the embodiment of the present application, a connecting screw hole 35 is further provided at the lower end of the connecting seat 30, and a threaded connecting column 24 is provided at a corresponding position of the inner wall of the outer shell 20. The external screw shell locks the connecting seat 30 to the outer shell 20 through the connecting screw hole 35 and the threaded connecting column 24. Here, by locking the connecting seat 30 and the outer shell 20 with screws, it is ensured that each wedge surface and the corresponding inclined surface are pressed tightly, thereby fixing the seal and preventing shaking and displacement under the impact of high-speed airflow, which leads to the occurrence of noise.

[0045] The present application also provides a hair dryer 1000, including a main unit 200 and the functional head 100 as described above. Since the hair dryer 1000 includes all the technical solutions of the above-mentioned functional head 100, it has the beneficial effects of all the technical solutions of the above-mentioned functional head 100, which will not be repeated here and are all within the protection scope of the present application.

[0046] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
