Detailed description of the invention

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in detail.

As shown in Fig. 1 ~ 10, a kind of gas-cooker, comprise stove body 1 and be connected with stove body 1 and can access the handle 2 of combustion gas, the outer end of handle 2 is provided with gas joint 3, and the passage in handle 2 is communicated with the blast tube in stove body 1.

The top layout of stove body 1 have around stove body 1 top ring-type fire dish 4 and be arranged at the firn-jet head 5 of stove body 1 center of top, the end face of fire dish 4 and firn-jet head 5 is all densely covered with fire jetting hole 6;

The alternate air duct 7 having a ring-type between fire dish 4 and firn-jet head 5;

As shown in Figure 3, the fire jetting hole 6 in fire dish 4 is along the edge stepped sinking ring-type arrangement from outside to inside of fire dish 4, and height and the firn-jet head 5 of the fire jetting hole 6 of fire dish 4 innermost circle maintain an equal level.

As shown in Figure 2, on stove body 1, the below of fire dish 4 offers the side air inlet 8 being communicated with air duct 7 and stove body 1 side.

As shown in Figure 4, fire dish 5 and stove status are from rear, clearly can see the combustion gas through hole 19 being communicated with blast tube in stove body 1, with the combustion gas circuit 20 below fire dish, combustion gas through hole 19 just and side air inlet 8 vertical interlaced arrange, combustion gas circuit 20 is just in time above side air inlet 8, like this, gas-cooker burning makes, the heat of fire dish 4 not only heats the combustion gas below it, also heated the air by side air inlet 8, and the temperature of air and fuel is all enhanced, contribute to burning, improving combustion efficiency.The fire jetting hole 6 of the gradin setting of fire dish 4 is as a stifled wall round air duct 7, during burning, the rising hot gases that the fuel gas buring that fire dish 4 and firn-jet head 5 spray produces makes to produce large negative pressure in air duct immediately, effect is contained due to fire dish 4 and firn-jet head 5, force air can only in large quantities from the side air inlet 8 enter, improve air-fuel ratio, but improve efficiency of combustion.

As shown in convex 2,5,9,10, the below of stove body 1 is also provided with one group and specializes in combustion gas to the combustion gas access device of firn-jet head 5, stove body entirety is supported by this combustion gas access device, combustion gas access device comprise upside down funnel shape pre-mixing cabin 9, be arranged at pre-mixing cabin 9 bottom inlet central authorities valve 10, cover the piezo 12 of pre-mixing cabin 9 bottom inlet and support the feet 18 of whole burning stove

The outlet at pre-mixing cabin 9 top is communicated with firn-jet head 5, as shown in Figure 6, the bottom of stove body 1 is provided with a firn-jet head air inlet 17 specialized in firn-jet head 5 and use, the outlet at pre-mixing cabin 9 top is then connected with this firn-jet head air inlet 17, as shown in FIG. 7 and 8, the porch of pre-mixing cabin 9 is provided with crossbeam 13, crossbeam is preset with the interface through hole 14 that applicable valve 10 connects;

As shown in Figure 5, the profile of the profile of piezo 12 and the entrance of pre-mixing cabin 9 adapts, piezo 12 offers the window 15 and installing hole of the same size with interface through hole 14 that match with crossbeam 13 profile, the arranged outside of piezo 13 has plectrum 16, fluctuation piezo 13 can regulate air to enter the flow of pre-mixing cabin 9, reaches the object of adjusting air-fuel ratio;

Valve 10 penetrates installing hole and is connected with interface through hole 14, also spring is provided with between valve 10 and piezo 12, the piezo 12 that spring is pushed down just is free to than stirring, and as shown in Figure 9, the side of valve 10 is provided with the premix hole 11 being communicated with valve 10 inner passage.When combustion gas flows into from valve 10 high speed, its flow at high speed produces negative pressure, in premix hole 11, bring portion of air into be mixed into into, then first mixed air-flow sprays into pre-mixing cabin 9 from valve 10, as shown in Figure 10, valve 10 faces the outlet of pre-mixing cabin 9, the negative pressure that while high velocity air flings outlet, it produces at a high speed also drives the air outside pre-mixing cabin 9 entrance to come in, firn-jet head 5 is entered after mixing with high velocity air secondary, combustion gas like this through the high air-fuel ratio of twice mixed combustion is burnt on firn-jet head 5, its efficiency of combustion is higher, and effects of energy conservation and environmental protection is better.

In like manner, the gas joint 3 of handle 2 outer end is provided with the piezo that can regulate air mass flow.

Only as described above, be only the preferred embodiment of the utility model, when can not limit the scope of the utility model enforcement with this, namely generally according to equivalence change simple done by the content described in the utility model claim and utility model description and modification, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
