[0028] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0029] Please also read Figures 1 to 4The embodiment of the utility model discloses a hair dryer that is convenient for heat dissipation. The hair dryer of the present scheme includes a blowing structure 1 and a handle structure 2. The handle structure 2 is connected to the blowing structure 1. A fan assembly 11 is arranged inside the blowing structure 1. An electric control element 21 and a heat dissipation duct 22 are arranged inside the handle structure 2. The heat dissipation duct 22 connects the air inlet end 111 and the air outlet end 112 of the fan assembly 11 and penetrates the electric control element 21. The heat dissipation duct 22 forms wind for heat exchange with the electric control element 21 under the action of the fan assembly 11. With such a design, by setting the heat dissipation duct 22 penetrating the electric control element 21 and forming wind for heat exchange with the electric control element 21 under the action of the fan assembly 11, the electric control element 21 can fully exchange heat with the wind in the heat dissipation duct 22, accelerate the heat dissipation of the electric control element 21, and thus avoid the electric control element 21 from being burned due to excessive temperature.

[0030] Among them, the blowing structure 1 also includes an air inlet 12 at the rear end and an air outlet 13 at the front end. The fan assembly 11 is arranged in the middle area of ​​the blowing structure 1, and the air inlet end 111 of the fan assembly 11 is arranged toward the air inlet 12, and the air outlet end 112 of the fan assembly 11 is arranged toward the air outlet 13.

[0031] In some embodiments, the heat dissipation air duct 22 is provided with a first air outlet 221 and a second air outlet 222. The first air outlet 221 is provided at the connection between the handle structure 2 and the blowing structure 1 and is connected to the air outlet end 112 of the fan assembly 11. The second air outlet 222 is provided at the connection between the handle structure 2 and the blowing structure 1 and is connected to the air inlet end 111 of the fan assembly 11. The wind in the heat dissipation air duct 22 flows from the first air outlet 221 to the second air outlet 222. With such a design, when the flow rate at the air outlet 112 of the fan assembly 11 is slow and the wind pressure is high, the air outlet 112 of the fan assembly 11 generates a blowing force, and the wind blown out of the fan assembly 11 enters the heat dissipation channel from the first air outlet 221. The wind in the heat dissipation channel takes away the heat of the electronic control component 21 and then flows out from the second air outlet 222. The wind flowing out from the second air outlet 222 is sucked into the fan assembly 11 from the air inlet end 111 of the fan assembly 11, and is finally blown into the external environment by the fan assembly 11.

[0032] Among them, the handle structure 2 is connected to the area of ​​the blowing structure 1 corresponding to the fan assembly 11, and the first air outlet 221 is arranged close to the air outlet end 112 of the handle structure 2, so that the blowing effect of the fan assembly 11 is better, and the second air outlet 222 is arranged close to the air inlet end 111 of the fan assembly 11, so that the air inlet end 111 of the fan assembly 11 has a better exhaust effect on the heat dissipation channel.

[0033] Furthermore, the hair dryer for heat dissipation further comprises a water blowing nozzle 3 detachably connected to the blowing structure 1. Considering that the air outlet end 112 of the fan assembly 11 requires a large wind pressure to form wind blowing toward the heat dissipation channel, preferably, the water blowing nozzle 3 comprises a pointed water blowing nozzle 3 and a conical water blowing nozzle 3 (such as Figure 1 With such a design, since the pointed water blowing nozzle 3 and the conical water blowing nozzle 3 have slow flow rates, the air outlet end 112 of the fan assembly 11 can form a relatively large wind pressure.

[0034] In some embodiments, the heat dissipation air duct 22 is further provided with a third air outlet 223 , which is provided on the handle structure 2 and communicated with the external environment. With such a design, when the flow rate at the air outlet 112 of the fan assembly 11 is fast and the wind pressure is low, the air outlet 112 of the fan assembly 11 generates suction. Under the action of the suction of the fan assembly 11, the wind in the external environment enters the heat dissipation channel from the third air outlet 223. The wind in the heat dissipation channel takes away the heat of the electronic control component 21 and then flows out from the first air outlet 221 near the air outlet 112 of the fan assembly 11 and the second air outlet 222 near the air inlet 111 of the fan assembly 11 respectively. The wind flowing out from the first air outlet 221 near the air outlet 112 of the fan assembly 11 is blown out of the external environment by the fan assembly 11, and the wind flowing out from the second air outlet 222 near the air inlet 111 of the fan assembly 11 is sucked into the fan assembly 11 from the air inlet 111 of the fan assembly 11, and is finally blown into the external environment by the fan assembly 11.

[0035] Further, considering that the air outlet end 112 of the fan assembly 11 requires a relatively small wind pressure to form wind blowing toward the heat dissipation channel, preferably, the water blowing nozzle 3 includes a flat head water blowing nozzle 3 (such as Figure 2 With such a design, since the flat-head water blowing nozzle 3 has a fast flow rate, the air outlet end 112 of the fan assembly 11 can form a relatively small wind pressure.

[0036] It is understandable that when the blowing structure 1 does not have the water blowing nozzle 3 , the flow rate is fast and the wind pressure is small, and the air also enters from the third air outlet 223 located on the blowing structure 1 .

[0037] In some embodiments, the hair dryer for heat dissipation further includes a base structure 4, and the handle structure 2 is detachably connected to the base structure 4. With such a design, when the user needs to use the hair dryer in handheld mode, the hair dryer body can be removed from the base structure 4, and the hair dryer body can be used by holding the hair dryer handle. When the user needs to use the hair dryer in fixed mode, the hair dryer body can be installed on the base structure 4, that is, the hair dryer is fixedly placed for use, which can free the user's hands and solve the problem of fatigue of the hands caused by holding the hair dryer for a long time, thereby meeting the different use needs of the user and improving the user's use experience.

[0038] Furthermore, the third air vent 223 is located at the connection between the handle structure 2 and the base structure 4. The base structure 4 is provided with a fourth air vent 41 and a fifth air vent 42 that are interconnected. The fourth air vent 41 is connected to the third air vent 223, and the fifth air vent 42 is connected to the external environment. With such a design, when the handle structure 2 is removed from the base structure 4 for use, the wind from the external environment enters the heat dissipation channel from the third air vent 223; when the handle structure 2 is installed on the base structure 4 for use, the wind from the external environment enters the base structure 4 from the fifth air vent 42, and enters the heat dissipation duct 22 through the fourth air vent 41 and the third air vent 223 in sequence.

[0039] It is understandable that in other embodiments, the third air outlet 223 may not be disposed at the connection between the handle structure 2 and the bottom structure. In this design, the base structure 4 does not need to be provided with the fourth air outlet 41 and the fifth air outlet 42, which are not limited here.

[0040] Furthermore, a plug-in slot is provided on the handle structure 2, the third air outlet 223 is located in the plug-in slot, a plug-in block is provided on the base structure 4, the fourth air outlet 41 is located on the plug-in block, and when the plug-in block is inserted into the plug-in slot, the fourth air outlet 41 is connected to the third air outlet 223.

[0041] The utility model provides a hair dryer that is easy to dissipate heat. The hair dryer includes a blowing structure 1 and a handle structure 2. The handle structure 2 is connected to the blowing structure 1. A fan assembly 11 is provided inside the blowing structure 1. An electric control element 21 and a heat dissipation duct 22 are provided inside the handle structure 2. The heat dissipation duct 22 connects the air inlet end 111 and the air outlet end 112 of the fan assembly 11 and penetrates the electric control element 21. The heat dissipation duct 22 forms wind for heat exchange with the electric control element 21 under the action of the fan assembly 11. With such a design, by providing the heat dissipation duct 22 penetrating the electric control element 21 and forming wind for heat exchange with the electric control element 21 under the action of the fan assembly 11, the electric control element 21 can fully exchange heat with the wind in the heat dissipation duct 22, accelerate the heat dissipation of the electric control element 21, and thus prevent the electric control element 21 from being burned out due to excessive temperature.

[0042] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
