[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1-3 A hot air circulation insulation vehicle of the present embodiment comprises a carriage 1 and a plurality of dining buckets 2. A plurality of pulleys are provided at the bottom of the carriage 1. A hot air circulation chamber 3 and a hot air circulation mechanism are provided in the carriage 1. The hot air circulation mechanism is a hot air blower, which is used to make the air in the hot air circulation chamber 3 flow and heat. A plurality of fixing holes 4 for cooperating with the dining buckets 2 are provided on the top of the carriage 1. The fixing holes 4 are connected to the hot air circulation chamber 3. The dining buckets 2 are put into the hot air circulation chamber 3 through the fixing holes 4. The upper handle position of the dining bucket 2 is always exposed outside the carriage 1. A self-sealing structure for closing the fixing holes 4 is provided in the hot air circulation chamber. When the dining bucket 2 is taken out of the hot air circulation chamber 3, the self-sealing structure closes the corresponding fixing holes 4 to prevent hot air leakage, so as to achieve good insulation effect and high safety.

[0027] As an optional solution of the present invention, the structure of the dining bucket 2 is a bucket structure with a handle at the upper end abutting against the top of the carriage 1, and the lower bucket body can extend into the hot air circulation chamber 3 through the fixing hole 4.

[0028] As an optional scheme of the present utility model, the self-sealing structure includes a first sealing plate 5 and a second sealing plate 6, and the first sealing plate 5 and the second sealing plate 6 are both provided with a plurality of through holes. When the first sealing plate 5 and the second sealing plate 6 close the fixing hole 4, the first sealing plate 5 and the second sealing plate 6 overlap with each other, and the through holes on the first sealing plate 5 and the second sealing plate 6 are staggered with each other. The first sealing plate 5 and the second sealing plate 6 are respectively located on both sides of the fixing hole 4 and the upper ends are rotatably connected to the carriage 1 through an elastic structure. The elastic structure is a combination of a rotating shaft and a torsion spring. The elastic structure drives the first sealing plate 5 and the second sealing plate 6 to rotate toward the direction of the fixing hole 4. Through the above design, the first sealing plate 5 and the second sealing plate 6 will not completely block one side of the dining bucket 2. Even if the first sealing plate 5 and the second sealing plate 6 are located on the side of the dining bucket 2, the hot air in the hot air circulation chamber 3 can also heat the dining bucket 2 through the through holes on the first sealing plate 5 and the second sealing plate 6, thereby further improving the insulation effect.

[0029] As an optional solution of the present invention, the upper end of the second sealing plate 6 is rotatably connected to the cushion block 7 through an elastic structure, the cushion block 7 is connected to the carriage 1, and the upper end of the first sealing plate 5 is directly rotatably connected to the carriage 1 through an elastic structure. The height of the cushion block 7 is consistent with the thickness of the first sealing plate 5. The setting of the cushion block 7 makes the first sealing plate 5 and the second sealing plate 6 fit closely together when they are overlapped, and the sealing effect is good, which can effectively prevent hot air leakage.

[0030] As an optional solution of the present invention, an extension ring 8 is provided around the fixing hole 4 on the top of the carriage 1, and the inner diameter of the extension ring 8 matches the outer diameter of the dining bucket 2. The extension ring 8 is provided on the side of the fixing hole 4 away from the hot air circulation chamber 3, that is, the outside of the carriage 1. When the bottom of the dining bucket 2 is located in the space within the extension ring 8, the first sealing plate 5 and the second sealing plate 6 are in a state of closing the fixing hole 4. At this time, the hot air in the hot air circulation chamber 3 cannot leak from the fixing hole 4, thereby avoiding the problem of hot air leakage when the dining bucket 2 is taken.

[0031] As an optional solution of the present invention, an extension ring 8 may be provided around the fixing hole 4 on the top of the carriage 1, and a sealing ring 9 may be provided on the inner peripheral wall of the extension ring 8. The sealing is achieved by the abutment between the sealing ring 9 and the dining bucket 2. This is simpler than controlling the sizes of the extension ring 8 and the dining bucket 2, and the processing cost is low.

[0032] As an optional solution of the present invention, the first sealing plate 5 and the second sealing plate 6 are both heat-conducting plates, so that the parts where the first sealing plate 5 and the second sealing plate 6 abut against the dining bucket 2 can also achieve good heat transfer to ensure the heat preservation effect.

[0033] As an optional solution of the present invention, the first sealing plate 5 and the second sealing plate 6 both include an upper connecting plate 10 and a lower connecting plate 11, the upper connecting plate 10 is connected to the carriage 1, the through holes are distributed on the lower connecting plate 11, the upper connecting plate 10 and the lower connecting plate 11 are magnetically plugged in, a magnetic plug block 12 is connected to the upper end of the lower connecting plate 11, the upper connecting plate 10 is made of metal that can be magnetically matched with a magnet and a slot that matches the magnetic plug block 12 is provided at the lower end, so as to facilitate the subsequent removal of the lower connecting plate 10 for cleaning.

[0034] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
