2. Technical proposal

In order to solve the problems, the invention adopts the following technical scheme.

A foldable portable barbecue oven comprises a barbecue structure, a barbecue oven main body, a charcoal placement structure and an ash receiving structure;

the barbecue structure is erected on the barbecue oven main body and is used for placing objects to be barbecue;

the charcoal placing structure is inserted into the barbecue oven main body and is used for placing charcoal for barbecue;

the ash receiving structure is arranged in the barbecue oven main body and is used for collecting carbon ash falling after the charcoal for barbecue of the charcoal placing structure is burnt out;

the barbecue structure, the charcoal placement structure and the ash receiving structure are sequentially arranged from top to bottom, and gaps for air circulation are formed in the barbecue structure, the charcoal placement structure and the ash receiving structure;

the barbecue oven comprises a main body and a main body, wherein the main body comprises two first oven surfaces which are symmetrical with each other and two second oven surfaces which are symmetrical with each other, the two first oven surfaces and the two second oven surfaces are distributed in a staggered way, and the first oven surfaces and the second oven surfaces are connected in a rotating way;

the two first furnace surfaces and the two second furnace surfaces jointly enclose a built-in storage space, the carbon placing structure and the ash receiving structure are arranged in the built-in storage space, and the ash receiving structure can rotate relative to the second furnace surfaces;

the two first furnace surfaces, the two second furnace surfaces and the ash receiving structure jointly form a barbecue oven body;

when the ash receiving structure rotates to a vertical state around one of the second furnace surfaces, the two first furnace surfaces are folded inwards and the two second furnace surfaces are mutually close to each other, so that the volume of the oven body of the barbecue oven is reduced.

Further, the first furnace surface comprises two first connecting parts and first rotating shafts respectively fixedly arranged at the left side end and the right side end of the two first connecting parts, the two first rotating shafts between the end parts of the two first connecting parts, which are close to each other, are connected in a rotating manner, the two first rotating shafts at the end parts of the two first connecting parts, which are far away from each other, are connected with the second furnace surface in a rotating manner, in a using state, the two first connecting parts are in a parallel state, in a folding state, the two first connecting parts are folded inwards at the same time, and the two folded first connecting parts are overlapped.

Further, the second furnace face includes second connecting portion, sets firmly in the second pivot of both sides end around the second connecting portion, locates the location portion of second connecting portion outside end and rotates the supporting part that is used for providing the support to second connecting portion that is connected on the location portion, second pivot on the second connecting portion rotates with first pivot on the first connecting portion and is connected, one of them second connecting portion outside end has seted up at least one third spacing hole, another one second connecting portion outside end has seted up at least two first spacing holes, and second connecting portion outside end has seted up at least one second spacing hole, the second spacing hole is located the downside in first spacing hole, and second connecting portion are used for providing the connection supporting point of putting charcoal structure and ash receiving structure.

Further, under two first stove faces fold inwards in opposite directions and two second stove faces draw close the state each other, the supporting part can be around the location portion upset to vertical ascending state to convenient portable when realizing the reduction of oven furnace body volume.

Further, the locating part is including dismantling the connection in the main locating rack of second connecting portion outside end, set up in the changeing the hole of one of them inside wall of main locating rack, set firmly in the vice locating rack of another inside wall of main locating rack and set up in the spacing groove of vice locating rack bottom, the supporting part rotates and connects between two changeing the hole, and the outer end that the supporting part is close to the changeing the hole is located the spacing groove, the biggest angle that the supporting part revoluted hole pivoted is one hundred eighty degrees, and under the oven main part state of use, the locating part provides the supporting role for second connecting portion and first connecting portion, under the oven main part state of not using, the locating part upwards overturns to the position that contacts with the second connecting portion, and the locating part after the upset can conveniently carry as the handle.
