The air duct component 2 is provided with at least two channels 21 spaced apart. Taking this embodiment as an example, there are two channels 21. The housing 1 has two air inlets 11 and two sets of air outlets 12. The two air inlets 11 are opened opposite to each other on the side wall of the housing 1. The two air inlets 11 and the two sets of air outlets 12 are all connected to the channels 21. The two sets of air outlets 12 correspond one-to-one with the two channels 21. In this embodiment, each set of air outlets includes one air outlet 12.

[0037] Combination Figure 1 and Figure 2 As shown, each channel 21 is connected to a set of fans 3. In this embodiment, each set of fans 3 includes one fan 3 fixed to the inner wall of the channel 21. A filter screen 4 is fixedly connected to the upper end of the duct component 2. The fan 3 is located between the filter screen 4 and the air outlet 12. A heating element 5 is fixedly connected to the inner wall of each channel 21. The heating element 5 is located between the fan 3 and the air outlet 12. Two sensors 6 are fixedly connected to the outer surface of the housing 1. The two sensors 6 correspond one-to-one with the two fans 3. The sensors 6 are located near the air outlet 12. A controller (not shown in the attached diagram) is fixedly connected inside the housing 1. The fan 3, heating element 5, and sensor 6 are all electrically connected to the controller. When the user's hand touches the sensor 6, the sensor 6 outputs a signal to the controller. The controller receives the signal and outputs a signal to the corresponding heating element 5 and fan 3. The heating element 5 and fan 3 are turned on. The fan 3 drives the airflow at the air inlet 11 to flow through the filter screen 4 and the heating element 5, and is discharged from the air outlet 12. The airflow between each fan 3 and the corresponding air outlet 12 is independent of each other, which can avoid airflow interference and ensure that the air blown out from the air outlet 12 is more stable.

[0038] The implementation principle of a hand dryer according to an embodiment of this application is as follows:

[0039] Using two sets of fans 3 can increase the air volume and air pressure of the hand dryer, better meet the air volume and wind speed requirements at the air outlet 12, and achieve rapid drying of hands. In addition, the setting of the sensor 6 and the controller can enable the hand dryer to control the operation of the fan 3 according to the sensing situation, making it convenient to use.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that, in combination with Figure 3 , Figure 4 and Figure 5 As shown, two air inlets 11 are located at the bottom of the housing 1, and two sets of air outlets 12 are arranged opposite each other. Each set of air outlets 12 includes one air outlet 12 formed on the housing 1. The two air outlets 12 are arranged opposite each other. A hand drying groove 13 is formed at one end of the housing 1, and each air outlet 12 communicates with the hand drying groove 13, which is located between the two air outlets 12. A sensor 6 is installed on the inner wall of the hand drying groove 13, and the sensor 6 is located above the air outlets 12.

[0042] In other embodiments, each group of air outlets 12 includes two air outlets 12, which are arranged along the width direction of the housing 1. The two air outlets 12 in different groups are arranged opposite to each other. Each channel 21 is fixedly connected to two branch pipes (not shown in the figure) at one end near the air outlet 12. The two branch pipes correspond one-to-one with the two air outlets 12 in the same group, and the branch pipes are connected to the air outlets 12. When a hand is placed in the hand dryer 13, the airflow at the air inlet 11 passes through the corresponding branch pipe and is discharged from the air outlet 12, drying the user's palms and backs of hands.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
