Description

Technical Field

[0001] The invention relates to the field of logistics distribution, and in particular to a distribution device capable of rapidly storing heat and slowly releasing heat. Background Art

[0002] For existing takeout delivery services on the market, insulated bags are generally used to keep food at a certain temperature during the meal preparation process. This traditional insulated bag is effective for frozen food, but it is not ideal for food that needs to be kept at a higher temperature. Because the taste of the food deteriorates, customers’ negative reviews of the merchants increase. Hot food also requires higher delivery time for riders. Riders often receive negative reviews because of delivery timeouts that cause food to lose temperature.

[0003] Therefore, when delivering food, riders will use insulated boxes or insulated bags for insulated delivery. However, the interior of existing insulated boxes or insulated bags is only paved with insulation materials, and they do not have a heating function. Therefore, heat loss will still occur during the delivery process. Although the temperature of the food can be maintained, for fried foods, pizza, and other foods that need to maintain high temperatures, once the temperature drops, the taste will deteriorate. Therefore, technicians set up heating equipment inside. For example, the utility model with publication number CN216917082U discloses a meal insulation bag with a self-heating function. By installing a heating patch, the air in the insulation box can be heated, thereby extending the insulation time of the meal and improving the insulation effect of the meal, which is beneficial to meal delivery. However, this heating equipment has low power and cannot maintain the high temperature of the food, and still cannot solve the problem. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a dispensing device with rapid heat storage and slow heat release.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

The tin foil heat-conducting plate comprises a PC plate body and an aluminum foil sheet laid on the upper surface of the PC plate body. The energy-storage heat-releasing plate is placed above the tin foil heat-conducting plate. The area of ​​the energy-storage heat-releasing plate is smaller than that of the tin foil heat-conducting plate, and the thickness of the energy-storage heat-releasing plate is greater than that of the tin foil heat-conducting plate.

[0007] Preferably, a paving groove is provided on the PC board at a location corresponding to where the aluminum foil is to be laid.

[0008] Preferably, the energy storage and heat release plate comprises a thick plate body having the function of storing energy and releasing heat, and heat release holes are provided on the thick plate body.

[0010] Furthermore, a strip-shaped bag-sealing magic sub-tie is sewn on the upper surface of the bag body, and a strip-shaped bag-sealing magic mother-tie is sewn on the inner side of the bag opening edge.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0022] Example

[0023] like Figure 1-5 As shown, a dispensing device with rapid heat storage and slow heat release includes an insulation bag 1, a tin foil heat conductive plate 2 placed inside the insulation bag 1 and capable of enhancing electromagnetic strength, and an energy storage heat release plate 3 cooperating with the tin foil heat conductive plate 2 for heat preservation.

[0024] The thermal insulation bag 1 comprises a bag body 11 with an opening toward one side and an interlayer filled with thermal insulation cotton, a bag opening sealing edge 12 which is integrally formed with the bottom end of the bag body 11 and is extended, a hand strap 13 sewn to the outside of the bag body 11, a first layer inner bag 14 sewn to the inner side of the bottom surface of the bag body 11 for accommodating a tin foil heat conducting plate 2, a second layer inner bag 15 sewn above the first layer inner bag 14 for accommodating an energy storage heat releasing plate 3, and an inner layer caulking cloth 16 which has one side sewn to the opening of the bag body 11 and the other side sewn to the bag opening sealing edge 12.

[0025] The upper surface of the bag body 11 is sewn with a strip of bag sealing magic sub-tape 111, and the inner side of the bag opening sealing edge 12 is sewn with a strip of bag opening sealing magic mother tape 121. Specifically, the bag opening sealing edge 12 can be pasted to the bag body 11 to achieve sealing, and the strip of bag sealing magic sub-tape 111 and the strip of bag opening sealing magic mother tape 121 can cooperate with the inner layer of filling cloth 16 to seal the insulation bag 1 for food delivery.

[0026] An inner bag strip magic sub-tie 141 is sewn on the upper surface of the first-layer inner bag 14, and an extended inner bag strip magic mother tag 151 is integrally formed at the opening of the second-layer inner bag 15. Specifically, after the energy storage and heat release plate 3 is loaded into the second-layer inner bag 15, it is fixed by means of the inner bag strip magic sub-tie 141 and the inner bag strip magic mother tag 151, which can prevent the energy storage and heat release plate 3 from sliding out and affecting the energy storage and heat dissipation effect.

[0027] The inner caulking cloth 16 is arranged in a triangular shape. Specifically, when the bag sealing edge 12 and the bag body 11 are sealed by pasting, the inner caulking cloth 16 can be folded and filled into the gap between the bag sealing edge 12 and the side of the bag body 11 to prevent heat loss.

[0028] The tin foil heat conductive plate 2 includes a PC board body 21 and an aluminum foil sheet 22 laid on the upper surface of the PC board body 21. The energy storage heat release plate 3 is placed above the tin foil heat conductive plate 2. The area of ​​the energy storage heat release plate 3 is smaller than that of the tin foil heat conductive plate 2, and the thickness of the energy storage heat release plate 3 is greater than that of the tin foil heat conductive plate 2.

[0029] The PC board 21 is provided with a laying groove 211 at a position corresponding to the aluminum foil 22 , which makes the aluminum foil 22 and the PC board 21 more closely combined, improves the stability and strength of the overall structure, and is also beneficial for the PC board 21 to conduct and dissipate heat.

[0030] The energy storage heat release plate 3 includes a thick plate body 31 with energy storage and heat release, and heat release holes 32 opened on the thick plate body 31. Specifically, the heat release holes 32 can release the heat of the thick plate body 31, and the released heat can keep the insulation bag 1 at a high temperature all the time.

[0031] In this embodiment, the energy storage heat release plate 3 is formed by mixing polyethylene and glass fiber in a ratio of 5:1 and then coating with galvanized sheet. Mixing polyethylene and glass fiber in a ratio of 5:1 can balance the flexibility of plastic and the strength of glass fiber, ensuring that the final product has a certain mechanical strength without being too brittle. The galvanized sheet provides additional corrosion protection and extends the service life of the energy storage heat release plate 3. In addition, the thermal conductivity of the galvanized layer also helps to improve the overall heat exchange efficiency.

[0032] In this embodiment, the energy storage temperature of the energy storage and heat release plate 3 is 100-120°C.

[0033] In this embodiment, the release temperature of the energy storage heat release plate 3 placed inside the heat preservation bag 1 is 80-100° C., and the continuous heat release time is 55-65 minutes.

[0034] The above embodiments of the present invention are not intended to limit the protection scope of the present invention, and the implementation modes of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
