In actual application, the above components can be optimized in shape, structure, quantity and other design factors, or replaced with existing designs or additional components.
[0029] The control box 3 in the figure is a hollow frame structure as a whole, which has a box body 31 and a box plate 32 structure. A control board 33 is installed in the box body 31. The control board 33 is installed in a conventional manner and is connected with the fan 81, the heating element 82, the first sensor 7, the second sensor 10 and the battery valve through the cable 41 to realize power communication assembly. The specific control mode and control circuit of the control board 33 can be in a conventional manner. In order to facilitate the assembly of the box body 31 and the cable 41 or the plug 1, the plug 1 is used to connect the external power supply, and a rubber sealing joint 2 is sleeved at the corresponding position to protect the cable 41 or the plug 1. The electromagnetic valve 34 is installed in the box body 31. The electromagnetic valve 34 adopts a conventional type to be fixed with the water pipe 42, and only needs to realize the opening and closing function of the water outlet pipe 43. In order to fix the cable 41 and the water pipe 42, the two components can be penetrated through a sleeve 5, and the sleeve 5 can be installed on a fixed surface such as the surface of a washbasin, so that the support 6 can also be supported.
[0030] The support 6 in the figure adopts a symmetrical design, that is, the support 6 has two groups of fans 81 and heating elements 82, and each group is arranged symmetrically, so that two workstations at the water outlet position can be used. The support 6 is hollow inside to place components such as the cable 41, the water pipe 42, the fan 81, the heating element 82 and the inner shell assembly 9. The support 6 is designed with a wire inlet 61 at the bottom to facilitate the insertion of the pipe, and a water outlet 62 is designed at the outlet end of the water outlet pipe 43 to facilitate the outlet of water.
[0031] The water outlet pipe 43, the fan 81 and the heating element 82 in the figure can adopt existing components, and the installation mode and installation position of the above components can be referred to the drawings.
[0032] The first sensor 7 and the second sensor 10 in the figure can adopt existing infrared sensing or laser sensing, and the control cooperation with the control panel 33 can also refer to the prior art. The first sensor senses the user's water demand, and the second sensor 10 senses the user's dry hand demand; as shown in the figure, the first sensor is installed at the water outlet 62 of the water outlet pipe 43, and the second sensor 10 is installed at the second air outlet 922 of the support 6.
[0033] The inner shell assembly 9 in the figure is designed with a first inner shell 91 and a second inner shell 92, and the two inner shells are spliced into the inner shell assembly 9 in a splicing manner. One inner shell assembly 9 places one fan 81 and one heating element 82. Specifically, the fan 81 and the heating element 82 are placed in the first inner shell 91. The second inner shell 92 is designed with a through hole 921 and an air outlet 922. The second sensor 10 is placed in the through hole 921 and covered and sealed with a cover plate 93. The air outlet 922 is located beside the through hole 921. The air outlet 922 is on the air supply path of the fan 81 and the heating element 82, so that the hot air can flow out.
[0034] In actual application, in order to maintain the constant temperature of the air outlet 922, an infrared distance sensor, a temperature sensor and the like can be added. In this way, according to the distance from the air outlet 922 to the hand, the relationship among the wind speed, the distance, the heating element 82 and the wind temperature attenuation is utilized, and the temperature of the heating element 82, i.e. the electric heating wire, is adjusted in time through a matching algorithm, so as to realize the constant wind temperature reaching the hand.
