Description

Technical Field

[0001] The utility model relates to the field of gas bottle heating, in particular to a constant temperature chassis device for a gas bottle. Background Art

[0002] Gas cylinders are essential facilities in home kitchens. When cold seasons come, the gasification volume is insufficient due to low temperature, and sufficient gasification cannot be carried out. Insufficient gas in the bottle will lead to weak fire during combustion, especially when there is little gas in the gas cylinder. The weak fire is particularly obvious. People often put the gas cylinder in a basin. The boiling water in the basin heats the bottom of the gas cylinder to raise its temperature. After the liquefied gas in the bottle is heated, it is easy to gasify and generate a certain pressure to achieve the purpose of sufficient combustion. However, the above operation is troublesome and increases the burden of use.

[0003] The patent number is CN200920112166.7, which discloses a constant temperature pad for the bottom of a gas cylinder, including a base, a container for heating the bottom of the gas cylinder and containing a heating medium, an upper cover on the upper end of the container, a heating device on the bottom of the container, a manual switch and a power connector electrically connected to an external power supply on the outer side of the base, and the heating device is electrically connected to the manual switch and the power connector. The temperature is increased, and then the gas cylinder placed on the upper surface of the base is heated, which prolongs the service life of the gas cylinder and avoids the trouble of people using hot water to heat the gas cylinder.

[0004] However, there are the following defects: when the gas volume inside the gas cylinder is above a certain weight, it does not need to be heated by a heating device, and heating a gas cylinder with sufficient gas volume will increase the pressure inside the tank, which will pose a safety hazard. Utility Model Content

[0005] The utility model provides a gas bottle constant temperature chassis device with a simple structure to solve the problems of the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A gas cylinder constant temperature chassis device includes: a base, a heating block, a control module and an external power supply, the upper end of the base is provided with a groove, the groove is slidably provided with a guide rod, the guide rod is sleeved with a spring, contact switches are provided on both sides of the groove, the heating block is matched and arranged above the groove, the lower end of the heating block is fixed on the guide rod, the control module includes a controller, a switch and a constant temperature controller, the controller is connected to an external power supply, the contact switch is electrically connected to the controller, the switch is electrically connected to the controller, and the constant temperature controller is electrically connected to the heating block and the controller.

[0007] As a further improvement, an annular limiting plate is provided at the upper end of the base.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] When the weight of the gas cylinder is greater than the set kilograms, the gas cylinder drives the heating block to move downward and compress the spring. At the same time, the bottom of the heating block touches the contact switch, and the contact switch transmits the signal to the controller. The controller turns on the switch to make the circuit non-conductive, and the heating block does not heat up, thereby ensuring safety; when the weight of the gas cylinder is less than the set kilograms, the gas cylinder drives the heating block to move downward and compress the spring, but the weight is less than the set pressure of the spring, the bottom of the heating block does not touch the contact switch, and the contact switch does not transmit the signal to the controller, and is in a normally closed state. The circuit is conductive, the heating block is heated, and the heating block is controlled by the thermostat to maintain a constant temperature. The heating block conducts heat to the gas cylinder body through the base, thereby improving gasification efficiency and saving energy. The heating situation is judged according to the specific weight of the gas cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
