In order to solve the second technical problem, preferably, each of the energy concentrating sub-bodies includes a transverse portion and a vertical portion, wherein the transverse portion and the vertical portion have through holes for the pan supporting legs to pass through, in a folded state between the energy concentrating sub-bodies, the transverse portion of each energy concentrating sub-body serves as a shielding portion for shielding a combustion portion of the burner, and in an expanded state between the energy concentrating sub-bodies, the vertical portions of each energy concentrating sub-body can together enclose a closed peripheral wall. Wherein each of said sub-shaped bodies is substantially sector-shaped, wherein each of said sub-shaped bodies of the present invention can slide radially inwards and outwards relative to the pot foot, either by one, by a pair or by all. When the pot is placed on the pot support legs of the base, the sub energy-gathering bodies which are arranged and moved slide outwards along the radial direction, and are expanded and opened, and the closed peripheral wall which is formed by the vertical parts of the sub energy-gathering bodies together can play a role in energy gathering, so that the combustion heat of the combustor in the combustion process is utilized and is reused for heating the pot; when the pot is taken up, the sub energy gathering bodies which are arranged to move can slide inwards along the radial direction, the transverse parts can shield the combustion part of the combustor, the combustion heat in the combustion process is prevented from flowing out, and the heat of flame can be accumulated on the sub energy gathering bodies.

To solve the third technical problem, it is preferable that the bases of the lateral portions of the adjacent sub-energy collectors are overlapped. Therefore, when each energy gathering sub-body slides outwards along the radial direction, the bottoms of the transverse parts of the adjacent energy gathering sub-bodies are mutually overlapped to form a closed bottom peripheral wall, and a better energy gathering effect is achieved.

a transmission rod (54) having a through hole (20) vertically passing through the sub-concentrator, the rod body of the transmission rod (54) having a third rack portion (541) also engaged with the second rack portion (531); thereby realizing that the sub-energy gathering bodies (11; 12; 13; 14) can realize radial sliding relative to the pot support leg (4) along with the up-and-down movement of the transmission rod (54) under the state that the pot is placed on the pot support leg (4).

8. A gas stove applying the energy-gathering cover as claimed in any one of claims 1 to 7, comprising:

a chassis (7), the chassis (7) having a top opening (71);

a cooktop panel (8) covering the top opening (71) of the base pan (7), the cooktop panel (8) having a central hole (81) through which a burner (6) of the burner (6) is partially exposed;

a liquid containing plate (9) which covers the central hole (81) of the stove panel (8), wherein the liquid containing plate (9) is provided with a mounting hole (91) which is communicated with the central hole (81);

the method is characterized in that:

the base (3) of the energy-gathering cover is arranged on the liquid containing disc (9), an opening (2) is formed by the surrounding of the inner side edges of the sub energy-gathering bodies (11; 12; 13; 14) of the energy-gathering cover and used for exposing the combustion part of the combustor (6), and the liquid containing disc (9) is provided with a through hole (92) for the transmission rod (54) of the transmission mechanism (5) to extend out.

9. The gas range of claim 8, wherein: the lower end of the transmission rod (54) is connected with an elastic piece (50), a support frame (72) is arranged on the chassis (7), the tail end of the elastic piece (50) is connected to the support frame (72), and the head end of the elastic piece (50) is connected to the lower end of the transmission rod (54), so that the sub energy gathering bodies (11; 12; 13; 14) always have the tendency of returning to a relatively furled state.

10. The gas range of claim 9, wherein: the supporting frame (72) comprises at least two supporting rods (721) and a supporting ring (722) for connecting the supporting rods (721), and the tail end of the elastic part (50) is connected to the supporting ring (722).
