The cross fixing frame 15 is fixedly installed at one end of the exhaust fan 10, and the cross fixing frame 15 is rotatably connected to the rotating shaft on the exhaust fan 10. The timing sensor 12 can turn on the four exhaust fans 10 within the set time. The exhaust fans 10 blow the exhaust baffle 13, and the spring 14 is stretched. The four exhaust baffles 13 are respectively away from the inner side walls of the first exhaust pipe 8 and the second exhaust pipe 9. At this time, the air inside the humidity instrument panel is discharged from the first exhaust hole 6 and the second exhaust hole 7, and a negative pressure is formed inside. In this way, the external airflow is affected by the negative pressure and then enters the humidity instrument panel through a number of air inlet holes 5 evenly distributed around the control button 17 for real-time measurement. According to the principle of fluid engineering, the aperture of the air inlet hole 5 is large inside and small outside. When air enters, it becomes gentle, thereby improving the sensitivity and accuracy of real-time measurement and improving the aesthetics, thereby achieving a unified improvement in aesthetics and function.

[0025] Further, such as Figure 1-Figure 5 As shown, a plurality of button holes 16 are provided on the button plate 4 and the upper shell 1, and the button holes 16 and the air inlet holes 5 are arranged on the same side of the upper shell 1.

At this time, the air inside the humidity instrument panel is discharged from the first exhaust hole 6 and the second exhaust hole 7, and a negative pressure is formed inside. In this way, the external airflow is affected by the negative pressure and then enters the humidity instrument panel through a number of air inlet holes 5 evenly distributed around the control button 17 for real-time measurement. According to the principles of fluid engineering, the aperture of the air inlet hole 5 is larger inside and smaller outside. When air enters, it becomes flat, thereby improving the sensitivity and accuracy of real-time measurement and improving the aesthetics, thereby achieving a unified improvement in aesthetics and function.

[0029] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0030] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0031] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
