This is an alternative form for a li tripod incense burner and appears as such in a portrait of the Qianlong Emperor surrounded by works of art, as shown in The Imperial Packing Art of the Qing Dynasty, The Palace Museum, Beijing, 1999, p. 113.  The apocryphal mark reads Xuande neifu (‘Made in the Inner Palace during the Xuande period’). 

The neifu ('Inner Palace') mark denotes imperial use, and can be found on ceramic jars from the early 15th century.  See a black jar from the Arthur Sackler Collection, with a neifu mark moulded in relief against a black glaze, illustrated by J. J. Lally & Co., Chinese Ceramics in Black and White, New York, 2010, cat. no. 35.
