2. Description of the Related Art
The brace rod 14 is led by a wire 16 to pass through the through-hole 111 of the annular body 11, and accordingly the supporting ribs 13 drive the main ribs 12 to spread outward along a radial direction. The yarn mesh 15 is completely spread along with the main ribs 12, and thus, the conventional cover 1 is in the shape of an umbrella. The spread conventional cover 1 is used to cover and protect food or items on a table from being ruined by mosquitoes and flies. However, the conventional cover 1 cannot maintain the temperature of the food or items disposed therein, so it is impossible to maintain the edible quality of the food or the items. Further, if it turns cold after a period of time, the food or the item in the conventional cover 1 must be heated before eating, so the eating process becomes complicated, and the eating time is prolonged. Moreover, after the food or item is heated, the taste and the quality become quite different.
Therefore, it is necessary to provide a heating and heat preservation cover and a heat preservation cover to solve the above problems.
The present invention is directed to a heating and heat preservation cover. The heating and heat preservation cover includes a pivot portion, a heat source device, and a cover portion. The pivot portion has at least one first joining portion. The heat source device is disposed on one end of the pivot portion. One end of each bracket has at least one second joining portion. The shape of the second joining portion matches that of the first joining portion, and the second joining portion moves along the first joining portion. An angle formed between an extension line of the two ends of the bracket and an axial extension line from the pivot portion to the heat source device is an acute angle. The cover portion is connected to the brackets.
Further, the present invention is directed to a heat preservation cover. The heat preservation cover includes a pivot portion and a plurality of blades. The pivot portion has a first joining portion. One end of each blade has at least one second joining portion. The shape of the second joining portion matches that of the first joining portion, and the second joining portion moves along the first joining portion. Therefore, by moving one of the blades, the other blades are driven to form a cover portion.
The heating and heat preservation cover or the heat preservation cover and a platform define an accommodation space for accommodating food or items. The heat source device can provide heat for the accommodation space, so as to maintain the temperature and the quality of the food or items disposed in the heating and heat preservation cover, maintain the freshness and the tastiness of the food or items after cooking, and avoid contact with and contamination from the outside.
In addition, since the heating and heat preservation cover can be flexibly folded, it is portable and can be easily received after being used, so that its volume is reduced.
One end of each bracket 23 has at least one second joining portion 231. The shape of the second joining portion 231 matches that of the first joining portion 212, and the second joining portion 231 moves along the first joining portion 212. An angle formed between an extension line of the two ends of the bracket 23 and an axial extension line from the pivot portion 21 to the heat source device 22 is an acute angle. In this embodiment, the bracket 23 further includes two bonding brackets 232 and 233 to be joined together.
The bracket 23 can be made of any material, for example, a metal or nonmetal material. The metal material includes stainless steel, elastic steel, iron, aluminum alloy, aluminum magnesium alloy, or other alloys. The nonmetal material includes wood, vine, bamboo, or a composite material thereof, or any plastic materials.
In this embodiment, the first joining portion 212 is an annular groove, and the second joining portion 231 is a neck structure caught in the annular groove, so that the brackets 23 can be movably spread along the annular groove. In other applications, the first joining portion 212 is an annular flange, and the second joining portion 231 is of a C-shaped structure. The C-shaped structure is caught on the annular flange (as shown in
It should be noted that the first joining portion 212 is not limited to the above structures, and the first joining portion 212 and the second joining portion 231 can be of any structures capable of being movably joined to each other.

The cover portion 24 is connected to the bracket 23. In this embodiment, the cover portion 24 is disposed between the adjacent brackets 23 except the adjacent bonding brackets 232 and 233, and the cover portion 24 is disposed on an inner lateral side of the brackets 23. However, the cover portion 24 can also be disposed on an outer lateral side of the brackets 23 or penetrate the brackets 23. The cover portion 24 driven by the brackets 23 is spread like an umbrella, or is folded in the same way.
The cover portion 24 can be of a mesh structure. The cover portion 24 can also be made of cloth or other materials. Moreover, in different applications, the cover portion 24 can be made of a transparent material, such as high molecular polymer, so as to clearly see the state of items in the heating and heat preservation cover 2.

The brackets 23 are spread, and the bonding brackets 232 and 233 are joined through the bonding elements, so that the heating and heat preservation cover 2 becomes an umbrella-shaped cover. The heating and heat preservation cover 2 and a platform (for example, a table top) define an accommodation space for accommodating food or items. The heat source device 22 provides heat for the accommodation space, so as to maintain the temperature and the quality of the food or items disposed in the heating and heat preservation cover 2, thus maintaining the freshness and tastiness of the food or items after cooking. Further, the heating and heat preservation cover 2 of the present invention can prevent mosquitoes or other insects from contaminating the food disposed therein.
It should be understood that the heating and heat preservation cover 2 of the present invention can be of different sizes. The heating and heat preservation cover with a smaller size can be applied to heat preservation and protection of food for an individual (for example, fried eggs, bread, take-away food, or small dishes of food), and the heating and heat preservation cover with a larger size can be applied to heat preservation and protection of food for several people (for example, a plurality of dishes).
In addition, one end of each bracket 23 is movably disposed on the lateral side 211 of the pivot portion 21, and the cover portion 24 disposed between the adjacent brackets 23 can be flexibly folded. Therefore, the heating and heat preservation cover is portable, and can be easily received after being used so that its volume is reduced.
Similarly, the heating and heat preservation cover 3 of the second embodiment can also maintain the temperature and the quality of food or items disposed therein, maintain the freshness and the tastiness of the food or items, and avoid contact with and contamination from the outside. Moreover, the heating and heat preservation cover 3 is portable, and can be easily received after being used so that its volume is reduced.
Each blade has an upper protruding edge and a lower protruding edge, for example, the blade 43 has an upper protruding edge 431 and a lower protruding edge 432, wherein the upper protruding edge and the lower protruding edge of each blade are located by two corresponding edges and along an end of each blade to the other end. By moving one of the blades, the other blades are driven to form a cover portion. For example, in
In various applications, the first joining portion can be an annular groove, and the second joining portion is a neck structure caught in the annular groove (referring to
The heat preservation cover 4 of the present invention can maintain the temperature and the quality of food or items disposed therein to maintain the freshness and the tastiness of the food or items, and avoid contact with and contamination from the outside to protect the food or items disposed therein. In addition, the heat preservation cover 4 of the present invention has simple structure, and can be easily spread to form a cover portion and received after being used, so that its volume is reduced and it is portable.
Therefore, the heat preservation cover 5 having the heat source device 52 according to the third embodiment of the present invention can not only avoid contact with and contamination from the outside but also maintain the temperature and the quality of food or items disposed therein to maintain the freshness and the tastiness of the food or items.
