It will be understood that when an element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element or there can be intervening elements (e.g., a third element) between the element and the other element.

The embodiment of the utility model provides a gas-electricity dual-purpose warmer, as shown in fig. 1-4, comprising a shell 100, wherein a fan assembly 200 and a heating chamber 300 are arranged in the shell 100, and the heating chamber 300 can be formed by enclosing a plurality of enclosing plates. The surface of the housing 100 is provided with the air outlet 101, the electric heating assembly 400 and the gas heating assembly 500 are fixed in the heating chamber 300, the electric heating assembly 400 can generate heat after being electrified, and the gas heating assembly 500 generates heat through the combustion of gas, so that the electric heating assembly 400 and the gas heating assembly 500 can heat the air in the heating chamber 300. The fan assembly 200 has an air inlet end and an air outlet end, the air inlet end is communicated with the heating chamber 300, the air outlet end is communicated with the air outlet 101, the fan assembly 200 extracts hot air in the heating chamber 300, and then the hot air is blown out through the air outlet 101, so that a user can get warm. Compared with the mode that the electric heating tube directly radiates heat outwards, the fan assembly 200 can blow hot air to a longer distance, so that the range of electric heating can be enlarged, a user can heat without approaching the warmer, and the effect of electric heating is improved.

In some embodiments, a combustion chamber 310 is disposed within the heating chamber 300, an electrical heating assembly 400 is located outside the combustion chamber 310, and a gas heating assembly 500 is disposed within the combustion chamber 310. Because the gas heating assembly 500 can generate flame, the temperature of the gas heating assembly 500 is higher, the electric heating assembly 400 and the gas heating assembly 500 are separated through the side wall of the combustion chamber 310, the flame is prevented from being directly baked to the electric heating assembly 400, a certain isolation protection effect is achieved on the electric heating assembly 400, and the service life of the electric heating assembly 400 can be prolonged. Meanwhile, the gas heating assembly 500 combusts gas in the independent combustion chamber 310, so that the flame is more stable and the combustion condition is better.

In this embodiment, the combustion chamber 310 may be formed by combining a plurality of coamings, or by combining a plurality of coamings with the inner wall of the heating chamber 300.
