[0029] Example 1

[0030] A hair dryer includes a housing 1, an air filter 2, and an air duct 3. The housing 1 is used to concentrate airflow and adjust the direction of the airflow. The air filter 2 is used to filter the air blown in by the hair dryer and also has a noise reduction function. An air inlet 11 is provided on the side of the housing 1, and the air blown out by the hair dryer enters the housing 1 through the air inlet 11. The air inlet 11 is connected to the air duct 3, which is used to connect to the air outlet of the hair dryer. The air filter 2 is placed between the air inlet 11 and the air duct 3, which can filter and reduce the noise of the air guided by the air duct 3 before it is delivered into the housing 1. An air guide 4 is installed inside the housing 1, which is used to adjust the direction of the airflow and guide the air blown in by the air inlet 11. The air is directed to the air outlet 12. The surface of the housing 1 has the air outlet 12. The air guide 4 is connected to the air outlet 12 and the air inlet 11. The air guide 4 includes an air guide groove 41 and an air guide plate 42. The air guide plate 42 is inclinedly arranged in the air guide groove 41. The air guide groove 41 is used to concentrate the air force. One end of the air guide plate 42 abuts against the edge of the air inlet 11. After the air enters the housing 1 from the air inlet 11, it will flow along the surface of the air guide plate 42. Because the air guide plate 42 is inclined, it will guide the air, making it less likely for the air to flow back. This allows the air to be blown out of the air outlet 12 faster and with higher utilization. Moreover, the change of air direction is a gradual transition process with less noise. By setting the air guide plate 42, not only can the air be guided, but the utilization rate of the air outlet can also be significantly improved. The air inlet 11 is located on the side of the housing 1, and the air outlet 12 is located on the top of the housing 1. The air direction can be quickly adjusted by the air guide vane 42, and the inclined air guide vane 42 reduces the noise of the air outlet. The inclination angle of the air guide vane 42 in the air guide groove 41 can be 10°~20°, 20°~30°, 30°~40°, 40°~50°, 50°~60°, 60°~70°, 70°~80°, or 80°~90°.

[0031] In this embodiment, a fixing post 43 is installed in the air guide groove 41, and the surface of the air guide plate 42 has a mounting hole 421. One end of the fixing post 43 passes through the mounting hole 421. By setting the fixing post 43, the air guide plate 42 can be fixed in the housing 1 to prevent the air guide plate 42 from shifting, ensuring the air guiding effect. The air can also be blown out along the side of the air guide post to the air outlet 12, thus playing the role of air guiding. A first support member and a second support member are arranged opposite each other on the side of the fixing post 43. An inclined body is provided at the bottom of the air guide plate 42. One end of the first support member abuts against the inclined body, and the bottom of the air guide plate 42 at one end of the second support member abuts against the first support member.

[0032] In this embodiment, a fixing member 5 is provided on the outer side of the air inlet 11, and one end of the fixing member 5 is detachably connected to the air guide duct 3. The fixing member 5 is ring-shaped and can be disassembled into two parts to fit over the air inlet 11, used to fix the air filter 2 and the air guide duct 3, thereby improving the stability of airflow transmission.

[0033] In this embodiment, one end of the fixing member 5 is provided with a connector 51, and one end of the air duct 3 is provided with a connecting hole 31. One end of the connector 51 is embedded in the connecting hole 31. Through the interlocking action of the connector 51 and the connecting hole 31, the fixing member 5 can be connected and fixed to the air duct 3, and the detachable function is realized.

[0034] In this embodiment, one end of the fixing member 5 is provided with a positioning groove 52, and one end of the air guide pipe 3 is provided with a positioning protrusion 32. One end of the positioning protrusion 32 is embedded in the positioning groove 52. By setting the positioning groove 52 and the positioning protrusion 32, one end of the fixing member 5 can be accurately positioned and connected to one end of the air guide pipe 3, while also preventing the one end of the fixing member 5 from shifting position.

[0035] In this embodiment, the surface of the air filter 2 has multiple through holes 21, which are respectively connected to the housing 1 and the air duct 3. By providing multiple through holes 21, the air filter 2 is honeycomb in shape, which allows large impurities to be blocked when the air passes through the air filter 2, while still allowing normal ventilation. In addition, it can divert the airflow and achieve a noise reduction effect.

[0036] Example 2

[0037] The difference between this embodiment and Embodiment 1 is that the housing 1 includes a first half-housing 13 and a second half-housing 14, which are detachably connected.

[0044] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0045] Obviously, this utility model includes a housing, an air filter, and an air duct. The housing is used to concentrate airflow and adjust the direction of the airflow. The air filter is used to filter the air blown in by the hair dryer and also plays a role in noise reduction. An air inlet is provided on the side of the housing, through which the air blown out by the hair dryer enters the housing. The air inlet is connected to the air duct, which is used to connect to the air outlet of the hair dryer. The air filter is placed between the air inlet and the air duct, which can filter and reduce the noise of the air guided by the air duct before it is delivered into the housing. The air duct is installed inside the housing. The air guide is used to adjust the direction of the air and guide the air blown from the air inlet to the air outlet. The surface of the housing has an air outlet, and the air guide is connected to the air outlet and the air inlet respectively. The air guide includes an air guide groove and an air guide plate. The air guide plate is inclinedly set in the air guide groove, and one end of the air guide plate abuts against the edge of the air inlet. After the air enters the housing from the air inlet, it will flow along the surface of the air guide plate. Because the air guide plate is inclined, it will guide the air and make it less likely for the air to flow back, so that the air can be blown out from the air outlet more quickly and with higher utilization.
