Embodiment 1

[0020] like Figure 1-2 As shown, a multifunctional packaging box based on constant temperature detection includes a packaging box main body 1, an end cover 2 arranged on the packaging box main body 1, and a bottom cover 5 arranged under the packaging box main body 1. The packaging box main body 1 It includes more than three combined structures, and the two combined structures are connected by zippers 4 , and a heating plate is arranged in the middle of the bottom cover 5 , and the heating plate is electrically connected to a constant temperature detection circuit.

[0021] In this scheme, the takeaway lunch box is placed in the packaging box, the inside of the packaging box can be heated through the heating plate at the bottom of the packaging box, the heating plate can be controlled by the switch button at the bottom for heating treatment, and the heating can be performed through the constant temperature detection circuit. The temperature is monitored to prevent overheating,...

Embodiment 2

[0028] On the basis of Embodiment 1, the specific connection of the heating plate constant temperature detection circuit is as follows: a transformer T is included, the primary side of the transformer T is externally connected to the mains, and the contacts of the heating plate G and the relay K1 are connected in series on the mains Switch J1, contact switch J2 of relay K2, the secondary side of the transformer T is connected to the input terminal of the rectifier bridge VD, the positive output terminal of the rectifier bridge VD is connected to the 4th and 8th pins of the 555 time base chip The positive output terminal of the rectifier bridge VD is connected with the 6th and 7th pins of the 555 solid base chip through the resistor R1, and the positive output terminal of the rectifier bridge VD is also connected with one end of the sliding rheostat RP. The other end of the sliding rheostat RP is connected to the negative output terminal of the rectifier bridge VD, the second pi...

Embodiment 3

[0035] On the basis of Embodiment 1, the packaging box is provided with a positioning device, the user can obtain the specific location through the mobile phone, and understand the delivery situation in real time. It can be returned when taking out, so that the packaging box can be used multiple times and shared, reducing environmental pollution and meeting the social development requirements of low-carbon and environmental protection.

Abstract

The invention discloses a multifunctional packaging box based on constant temperature detection, and relates to the technical field of product packaging. The multifunctional packaging box comprises apackaging box main body, an end cover arranged on the top of the packaging box main body and a bottom cover arranged at the bottom of the packaging box main body. The packaging box main body comprisesmultiple combined structures, the combined structures are connected through zippers, the middle of the bottom cover is provided with a heating plate, and the heating plate is electrically connected with a constant temperature detection circuit. In the scheme, the interior of the packaging box is heated through the heating plate at the bottom of the packaging box, the problem that take-out food iscooled in the delivery process, and therefore the taste of the take-out food and client experience are affected is prevented, meanwhile, direct eating and storage treatment are convenient since the packaging box main body is connected through the zippers, the structure of the packing box is simple and convenient to achieve, cleanliness of the interior of the packaging box can be ensured through appropriate wiping after eating is finished, secondary recycling is carried out, and folding storage treatment is convenient.

Description

technical field [0001] The invention relates to the technical field of product packaging, in particular to a multifunctional packaging box based on constant temperature detection. Background technique [0002] With the acceleration of the pace of life and changes in lifestyles, the express delivery industry is increasingly developed, followed by fewer and fewer people cooking at home. The door-to-door delivery business of fast food restaurants has brought a lot of convenience to people's lives. However, at present, the food delivery staff must pack the meal box with the food delivery bag when delivering the food, and then send it to the customer after the package is completed. The way of delivering food with the food delivery bag will increase the pressure on environmental protection with the development of the fast food industry, resulting in more environmental pollution. There is a lot of white garbage, which does not meet the needs of green environmental protection, and t...
