Chassis and air outlet device

The utility model provides a chassis and an air outlet device. The trundles are arranged on the bottom shell, the trundles are located at the vertex positions of a regular polygon, and the number of edges of the regular polygon is larger than or equal to 5. In the utility model, the plurality of trundles are positioned at the vertex positions of the regular polygon, so that the pressure borne by the chassis can be distributed more uniformly. Meanwhile, due to the fact that the number of edges of a regular polygon formed by the trundles is larger than or equal to 5, the diameter of the bottom shell can be reduced on the basis that enough anti-toppling performance is guaranteed, cost control is facilitated, and meanwhile follow-up operation such as transportation and packaging is facilitated. 本实用新型提供一种底盘和出风装置，包括：底壳；若干个脚轮，设置在所述底壳上，若干个所述脚轮处于正多边形的顶点位置，所述正多边形的边数大于等于5。本实用新型中，多个脚轮处于正多边形的顶点位置，因此可以对底盘承受的压力进行更加均匀的分配。同时，由于脚轮形成的正多边形的边数大于等于5，因此可以在确保具有足够的抗倾倒性能的基础上，将底壳的直径变小，从而有助于对成本进行控制，同时也方便进行后续的运输和包装等操作。
