[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a multi-mode heat preservation dining car, wherein a plurality of cavity structures are provided on the front wall of the dining car body 1, and a door panel 3 is hingedly installed at each cavity structure, and a door handle and a locking structure are provided on the door panel 3 to facilitate closing and opening of the cavity structure. In addition, a cavity structure is also provided at the bottom of the dining car body 1.

[0026] The heat preservation chamber 2 is fixedly mounted in the multiple cavity structures above. The bottom surface of the inner cavity of the heat preservation chamber 2 is provided with a plurality of support bars 2.1 extending in the longitudinal direction, respectively. The two ends of the bottom plate of the heat preservation chamber 2 are respectively provided with an exhaust cavity 2.2 and an air inlet cavity 2.4. The bottom surface of the inner cavity of the heat preservation chamber 2 is located between two adjacent support bars 2.1 above the exhaust cavity 2.2 and is provided with a plurality of exhaust holes 2.6. The bottom surface of the inner cavity of the heat preservation chamber 2 is located between two adjacent support bars 2.1 above the air inlet cavity 2.4 and is provided with a plurality of air inlet holes 2.7. The rear wall of the exhaust cavity 2.2 is provided with an exhaust connector 2.3, and the rear wall of the air inlet cavity 2.4 is provided with an air inlet connector 2.5.

[0027] The sealing assembly 4 includes a beam 1 4.2 arranged horizontally on both sides of the front end of the bottom of the inner cavity of the heat preservation chamber 2, a plurality of strip plates 4.1 whose front ends are vertically fixed to the rear wall of the beam 1 4.2 and are respectively slidably connected between two adjacent support strips 2.1 along the longitudinal direction to cover the air inlet holes 2.7 and the exhaust holes 2.6, a beam 2 4.3 extending horizontally and whose front wall is vertically fixedly connected to the rear end of the strip plate 4.1, a beam 3 4.4 arranged parallel to the rear side of the beam 2 4.3 and fixedly connected to the rear wall of the heat preservation chamber 2, and a spring 4.5 vertically connected between the beam 2 4.3 and the beam 3 4.4, and the strip plate 4.1 is provided with through holes 4.1.1 corresponding to the air inlet holes 2.7 and the exhaust holes 2.6. When the door panel 3 is closed, the cross beam 1 4.2 is pushed backward, so that the strip plate 4.1 is in the rear position through the cross beam 2 4.3 compressing the spring 4.5, and the through hole 4.1.1 is respectively opposite to the air inlet 2.7 and the exhaust hole 2.6. When the door panel 3 is opened, the backward push on the cross beam 1 4.2 is released, and the strip plate 4.1 moves forward under the rebound force of the spring 4.5, and the through hole 4.1.1 is respectively staggered with the air inlet 2.7 and the exhaust hole 2.6.

[0028] The heating assembly 5 includes a cabinet 5.1 inserted into the bottom cavity of the dining car body 1, a battery panel 5.2 arranged at the front of the inner cavity of the cabinet 5.1, a heating box 5.3 arranged at the rear end of the inner cavity of the cabinet 5.1, and an electric heating wire 5.4 arranged in the inner cavity of the heating box 5.3. The two ends of the front wall of the heating box 5.3 are respectively provided with a connecting pipe 1 5.6 and a connecting pipe 2 5.7, and the connecting pipe 2 5.7 is connected to the air inlet connector 2.5. An air pump 5.5 is fixed to the inner cavity of the cabinet 5.1 at a position in front of the connecting pipe 1 5.6, and the connecting pipe 1 5.6 is connected to the output end of the air pump 5.5, and the input end of the air pump 5.5 is connected to the exhaust connector 2.3. The battery panel 5.2 is used to provide electrical energy for the air pump 5.5 and the electric heating wire 5.4.

[0029] In summary, when in use, the food is classified and placed in each insulation chamber 2, and the food at the bottom is supported on the support bar 2.1. The air pump 5.5 is running to form a circulating airflow. After the airflow is heated by the electric heating wire 5.4 in the inner cavity of the heating box body 5.3, it enters the air inlet chamber 2.4 through the connecting pipe 2 5.7 and the air inlet joint 2.5 in turn. At this time, the door panel 3 is in a closed state, that is, the through hole 4.1.1 is directly connected to the air inlet hole 2.7 and the exhaust hole 2.6 respectively. The hot air flow in the air inlet chamber 2.4 is discharged into the insulation chamber 2 through the air inlet hole 2.7 to heat and keep the food warm. The air in the insulation chamber 2 enters the exhaust chamber 2.2 from the exhaust hole 2.6, and then enters the input end of the air pump 5.5 through the exhaust interface 2.3. The air pump 5.5 then discharges the air into the inner cavity of the heating box body 5.3 through the connecting pipe 1 5.6, and circulates in sequence to ensure the insulation effect of the food.

[0030] When food needs to be taken, the corresponding door panel 3 is opened. After the door panel 3 is opened, the entirety of the beam 1 4.2, the strip plate 4.1 and the beam 2 4.3 moves forward under the rebounding action of the spring 4.5, so that the through holes 4.1.1 are staggered with the air inlet 2.7 and the air outlet 2.6, that is, the air inlet 2.7 and the air outlet 2.6 are closed at this time, thereby reducing the overflow of hot air flow and reducing the heat loss when taking food.

[0031] The battery panel 5.2 is a rechargeable battery, and a charging interface 1.1 electrically connected to the battery panel 5.2 is provided at the bottom end of one side wall of the dining car body 1, so as to recharge the battery panel 5.2 through the charging interface 1.1.
