However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

A first embodiment of the present invention relates to a hand dryer, as shown in fig. 1 and 2, including: the shell body 1 is provided with an air inlet 11 and an air outlet 12 communicated with the air inlet 11, the shell body 1 is also provided with a positioning support 5, and the shell body 1 can be fixed on a wall surface 6 through the positioning support 5. As shown in fig. 2 and 3, the hand dryer of the present embodiment further includes: a blower and a runner 3. The air supply device is a blower 2 and is arranged in the casing 1, and the blower 2 is used for compressing the outside air from an air inlet 11 of the casing 1 and blowing out the compressed air from an air outlet 12 of the casing 1. The rotating wheel 3 is rotatably disposed on one side of the housing 1 where the air outlet 12 is disposed, and as shown in fig. 3 and 4, a plurality of guiding air ducts 31 are disposed in the rotating wheel 3, each guiding air duct 31 is annularly disposed around a wheel center of the rotating wheel 3, and in this embodiment, air outlet directions of the guiding air ducts 41 are different.

As shown in fig. 2, the hand dryer of the present embodiment further includes: and the driving device 4 is connected with the rotating wheel 3 and is used for driving the rotating wheel 3 to rotate. In practical application, after the driving device 4 drives the rotating wheel 3 to rotate towards the same direction by a preset angle, each guide air duct 31 in the rotating wheel 3 can be sequentially communicated with the air outlet 12 on the shell 1, so that the hand dryer can always perform air outlet at the same position, when the air outlet of the hand dryer is realized in the middle, the air outlet angle during air outlet can be changed according to the requirement of a user, and each guide air duct 31 is arranged in the rotating wheel 3, so that each guide air duct 31 can have better sealing performance, the loss in energy is avoided, and the hand dryer can have larger air outlet air volume.

Specifically, in order to achieve effective control of the driving device 4, so that the driving device 4 can drive the rotary wheel 3 to rotate around the wheel center to a proper position, as shown in fig. 6, the hand dryer of the present embodiment further includes: and the main control module is electrically connected with the driving device 4. In practical application, the main control module may be configured to receive a control signal, and control the driving device 4 according to the received control signal, so that the driving device 3 may drive the rotating wheel 3 to rotate around the wheel center by a preset angle under the control of the main control module. For example, as shown in fig. 1, a corresponding control area (not shown) may be disposed on the casing 1 of the hand dryer, where the control area may be a key control area formed by combining physical keys and/or touch keys, and a user may send a control signal to the driving device 4 by operating the corresponding key, so that the driving device 4 drives the wheel 3 to rotate to a proper position accurately. Of course, the control region may also be a gesture control region, and the control of the driving device 4 by the main control module can be realized by sensing the gesture operation of the user, which is not described in detail in this embodiment.

Note that, in the present embodiment, as shown in fig. 3 and 4, the above-mentioned runner 3 includes: a first surface 32 opposite to the housing 1, a second surface 33 opposite to the first surface 32, and a side 34 connecting the first surface 32 and the second surface 33. And each respective guide duct 31 includes: an air inlet end 311, an air outlet end 312, and an air duct main body 313 connected with the air inlet end 311 and the air outlet end 312 respectively. The air inlet ends 311 of the guide air ducts 31 are all disposed on the first surface 32 and are annularly disposed around the wheel center of the rotating wheel 3, so that after the driving wheel 3 is driven to rotate by a preset angle by the driving device 4, the air outlet 12 on the housing 1 can be communicated with one of the air inlet ends 311 on the rotating wheel 3 and disconnected from the air inlet ends 311 of the other guide air ducts 31, thereby ensuring that the air blown out from the air outlet 12 of the housing 1 can only enter one of the guide air ducts 31 to be sent out, as shown in fig. 2, and further achieving effective adjustment of the blowing angle. In addition, in order to ensure that the air outlet directions of the guide air ducts 31 are different, as shown in fig. 4, a part of the air outlet ends 312 of the guide air ducts 31 may be disposed on the side surface 34 of the runner 3, and the other parts of the air outlet ends 312 of the guide air ducts 31 may be disposed on the second surface 33 of the runner 3, and in any guide air duct 31, the air duct main body 313 is a bent channel connecting the air inlet end 311 and the air outlet end 312, and the bending angles and/or the bending directions of the bent channels are different, thereby ensuring that each guide air duct 31 can have different air outlet directions.

For example, in the present embodiment, as can be seen from fig. 5a to 5f, six guiding air ducts 31 are provided in the runner 3 in the present embodiment, and by changing the position of the air outlet end 312 of each guiding air duct 31 and the bending angle and the bending direction of the duct main body 313 of each guiding air duct 31, the six guiding air ducts 31 can all have different air outlet directions, so that the air outlet direction of each guiding air duct 31 in the present embodiment can be from the direction parallel to the axis of the runner 3 in fig. 5a, i.e. vertical downward air outlet, to the direction perpendicular to the axis of the runner 3 in fig. 5d, i.e. horizontal forward air outlet, and then from the horizontal forward air outlet in fig. 5d to the upward forward air outlet in fig. 5f, the angle of the air outlet direction is gradually increased from fig. 5a to fig. 5f, the upward angle of each guiding air duct 31 can be sequentially arranged around the center of the runner from bottom to top, the hand dryer of the embodiment can realize that the air outlet direction can be adjusted from-45 degrees to 135 degrees in a multi-gear manner by rotating the rotating wheel 3. Therefore, in the practical application process, the user can drive the rotating wheel 3 to rotate by controlling the driving device 4, so as to realize the communication between the corresponding guiding air duct 31 and the air outlet 12, and meet the use requirement of the user. Moreover, due to the air outlet mode, the guide air ducts 31 are arranged around the wheel center of the rotating wheel 3 in a surrounding mode, so that the guide air ducts 31 communicated with the air outlet 12 can be always positioned in the middle of the hand dryer, a user can adjust the posture of the hand without matching with the position of the air outlet end 312 when using the hand dryer, and the use experience of the user is improved.

It should be noted that, in the present embodiment, only a part of the air outlet ends 312 of the guide air ducts 31 is disposed on the side surface 34 of the wheel 3, and the other part of the air outlet ends 312 of the guide air ducts 31 is disposed on the second surface 33 of the wheel 3, but in the practical application, the air outlet ends 312 of the guide air ducts 31 may be disposed on the second surface 33 of the wheel 3, that is, each guide air duct 31 can only outlet air from below the wheel 3, or the air outlet ends 312 of the guide air ducts 31 may be disposed on the side surface 34 of the wheel 3, that is, each guide air duct 31 can only outlet air from the front side of the wheel 3, and the position of the air outlet end 312 of each guide air duct 31 is not specifically limited in the present embodiment.

However, as a preferable scheme, in the present embodiment, as shown in fig. 3 and 4, the air inlet end 311 of each guide air duct 31 may be equidistantly arranged around the wheel center of the rotating wheel, so that the rotation angle between every two adjacent guide air ducts 31 is the same, thereby further facilitating the control of the main control module on the driving device 4. Meanwhile, in order to further reduce the energy loss during the air outlet, as shown in fig. 1, the air inlet 11 and the air outlet 12 are respectively arranged at two sides of the housing 1 along the height direction of the housing 1, so that the air duct path in the housing 1 can be shortest, thereby ensuring that the air flow entering from the air inlet 11 can be directly sent out from the air outlet 12 after being compressed by the air blower 2, and avoiding the energy loss caused by the overlong air duct path.

Note that, as shown in fig. 2, the driving device 4 according to the present embodiment includes: the motor 41 and the transmission shaft 42 are connected with the output shaft of the motor 41, the motor 41 is arranged in the shell 1, and the transmission shaft is connected with the wheel center of the rotating wheel 3, namely, is coaxially fixed with the rotating wheel 3. In addition, the motor 41 is electrically connected to the main control module, so that the motor 41 can drive the runner 3 to rotate through the transmission shaft 42 under the control of the main control module.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
