These main consumer groups include camping enthusiasts, outdoor explorers and residents seeking unique leisure experience. These consumers' demand for products shows diversification and individualization, not only pay attention to the basic cooking and heating function of products, but also pay attention to the portability, safety, environmental protection and multifunction of products.

[0003] At present, the barbecue stove, fire stove, heating fireplace on the market are various and relatively single in function, consumers need to buy and carry multiple different types of stoves at the same time, which leads to a significant reduction in the economy, portability and experience of using the stove. The classification and advantages and disadvantages of the existing common stoves are briefly summarized as follows:

[0004] 1. Barbecue stove

[0005] The existing barbecue stove can be divided into traditional horizontal type and hanging type smoldering stove, among which the traditional horizontal type barbecue stove has two forms of manual turning food and chain transmission to realize automatic turning food. The hanging smoldering stove adopts barrel type layout, charcoal is arranged in the middle, food is hung and roasted in the barrel, and the food taking and placing ways have barrel top barrel opening and barrel side wall flat opening.

[0006] The advantages of horizontal barbecue stove are convenient to take food, easy to spray seasoning, convenient to observe food maturity, and low requirement for sign shape and material. The main disadvantages are that the charcoal is directly below the food, and the process of oil dripping, brushing and seasoning of food will produce thick smoke or even fire, which needs to be handled immediately, otherwise the food will be blackened or burned, and the surrounding environment will be greatly affected. The operator often feels busy and the number of food cooked at the same time is small, and the experience of the operator and the diners is poor. Although the automatic turning function of the stove can automatically turn the food, it cannot solve the problem of thick smoke and fire, and it also needs to be operated manually. At the same time, the chain transmission turning also needs to be equipped with special signs in specific positions, which is very inconvenient to operate.

[0007] The advantages of the hanging smoldering stove are that the oil fume on the side of the charcoal fire is small, no open fire occurs, and more food can be cooked at the same time. The disadvantages are that it is inconvenient to observe the maturity of the food, the food is prone to be undercooked or burnt; it is inconvenient to take out the food, a special hook or an anti-burning glove is needed; it is difficult to turn over the food, which causes uneven cooking maturity or complicated operation; in addition, the hanging smoldering stove cannot conveniently spray seasonings during cooking, which needs to be pre-marinated or sprayed, so that the seasonings are burnt and the taste is poor.
