一般的香炉在设计的时候，可以分为无足、三足和四足这三种。所谓的无足，就是指香炉为普通碗状，普通防止在桌面或者地面。一般无足的香炉由于设计等原因，会以小型香炉的方式出现。
When designing a general incense burner, it can be divided into three types: barefoot, tripod and quadruped. The so-called lack of feet means that the censer is in the shape of an ordinary bowl, which is generally prevented from being on the table or on the ground. Because of the design and other reasons, the general insufficient censers will appear in the form of small censers.
三足的香炉和四足的香炉相似，但一般四足香炉的体积会略大于三足香炉。三足香炉的原理来源于三角形是几何图形中稳固的形状，所以一般设计成三足的香炉非常不易倒塌。而四足的香炉一般会用在寺庙中作为供香使用，外形也会设计成方形，再搭配一些庄严的花纹图案，给人一种庄重的感觉。
The three legged censer is similar to the four legged censer, but generally the volume of the four legged censer is slightly larger than the three legged censer. The principle of tripod censer comes from the fact that triangle is a solid shape in geometry, so it is very difficult for tripod censer to collapse. The quadruped incense burner is generally used in temples for incense, and its shape is also designed to be square, with some solemn patterns, giving a solemn feeling.
