[0024] Working principle:

[0025] The temperature control device is mainly composed of a temperature control barrel 1, a heat preservation barrel 6, a handle 7, a fixing seat 4, a barbell piece 5, a quick connection assembly 3 and a heat preservation assembly 2, wherein the temperature control barrel 1 is the core component, a plurality of heat preservation barrels 6 are fixedly connected to the outer wall of the temperature control barrel 1, these heat preservation barrels 6 are arranged in a ring array along the central axis of the temperature control barrel 1, forming a preliminary heat preservation layer, reducing the loss of heat to the external environment, at the same time, the handle 7 is also arranged in a ring array along the central axis of the temperature control barrel 1, facilitating the movement and operation of the device by the operator.

[0026] At the bottom of the temperature control barrel 1, the fixing seat 4 is sealed by a sealing ring, and the barbell piece 5 is fixedly installed on the top of the fixing seat 4, which ensures the relative closed environment of heat circulation in the temperature control barrel 1, reducing the possibility of heat loss from the bottom.

[0028] When there is heat in the temperature control barrel 1, hot air will naturally rise, since the bottom of the gas collecting hood 25 is fixedly connected with the top of the temperature control barrel 1, the hot air will first gather in the gas collecting hood 25, then the hot air will enter the air guide pipe 21 through the connecting pipe 24, and then the hot air will be distributed to each exhaust pipe 23 through the air guide pipe 21, in this process, the hot air forms a circulating path in the temperature control barrel 1, so that the heat can be more evenly distributed in the internal space of the temperature control barrel 1, thereby slowing down the temperature drop speed of the barbell piece 5.

[0029] In addition, the inner wall of the temperature control barrel 1 is fixedly connected with the outer wall of the heat preservation inner cylinder 22, and the outer wall of the air guide pipe 21 is fixedly connected with the inner wall of the heat preservation barrel 6, which further enhances the heat preservation performance of the whole device, reducing the loss of heat to the outside through the barrel wall.
