All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following disclosure provides many different embodiments, or examples, for implementing different structures of the utility model. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the utility model. Furthermore, the present utility model may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

For ease of description, spatially relative terms, such as "inner," "outer," "lower," "upper," "above," "front," "rear," and the like, may be used herein to describe one element's or feature's relative positional relationship or movement to another element's or feature as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure experiences a position flip or a change in attitude or a change in state of motion, then the indications of these directivities correspondingly change, for example: an element described as "under" or "beneath" another element or feature would then be oriented "over" or "above" the other element or feature. Accordingly, the example term "below … …" may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein interpreted accordingly.

Because the air inlet 411 is smaller and the arrangement area of the plurality of swing blades 44 is larger, by arranging the flow guide piece 46, the cold air entering the cooling cabin 41 through the air inlet 411 can be dispersed to the plurality of swing blades 44, and the temperature of the cooling cabin 41 can be more uniform.

In addition, in other examples, the temperature sensor W and the humidity sensor X may be combined into one device, i.e., a temperature and humidity sensor.
