Embodiment 1

[0063] Phosphoric acid and Al(OH) 3 The reaction generates aluminum dihydrogen phosphate solution, phosphoric acid and MgO react to generate magnesium dihydrogen phosphate solution, the aluminum dihydrogen phosphate solution and the magnesium dihydrogen phosphate solution are mixed in a certain proportion to form a mixed solution, and distilled water is added to dilute to make the dihydrogen phosphate in the solution. The concentration of aluminum was 89 g / L, and the concentration of magnesium dihydrogen phosphate was 9.5 g / L. Add a certain amount of CrO to the mixture 3 , so that CrO 3 The concentration of 2.5g / L. Then react with a certain amount of reactive pigment aluminum powder in a ball mill to obtain an orange suspension which is the base material of the coating. A certain amount of aluminum powder was added to the base material of the coating so that the concentration of the aluminum powder was 1.2 g / L. Disperse with high-speed stirring for about half an hour to ob...

Embodiment 2

[0066] Phosphoric acid and Al(OH) 3 The reaction generates an aluminum dihydrogen phosphate solution, and the aluminum dihydrogen phosphate solution is added to distilled water to dilute, so that the concentration of the aluminum dihydrogen phosphate in the solution is 98.5 g / L. Then add a certain amount of CrO 3 , so that CrO 3 The concentration is 3g / L. Then react with a certain amount of reactive pigment aluminum powder in a ball mill to obtain an orange suspension which is the base material of the coating. A certain amount of aluminum powder was added to the base material of the coating so that the concentration of the aluminum powder was 1.5 g / L. Disperse with high-speed stirring for about half an hour to obtain phosphate aluminum powder coating. Before use, water is used as a diluent to adjust the viscosity to 25cp, and it is coated on the pipe wall of the aluminum pipe to form a thermal insulation pipe.

[0069] Preparation of raw materials for thermal insulation coating

[0070] Phosphoric acid and Al(OH) 3 The reaction generates aluminum dihydrogen phosphate solution, phosphoric acid and MgO react to generate magnesium dihydrogen phosphate solution, the aluminum dihydrogen phosphate solution and the magnesium dihydrogen phosphate solution are mixed in a certain proportion to form a mixed solution, and distilled water is added to dilute to make the dihydrogen phosphate in the solution. The concentration of aluminum was 96 g / L, and the concentration of magnesium dihydrogen phosphate was 3.5 g / L. Add a certain amount of CrO to the mixture 3 , so that CrO 3 The concentration of 3.25g / L. Then react with a certain amount of reactive pigment aluminum powder in a ball mill to obtain an orange suspension which is the base material of the coating. A certain amount of aluminum powder is added to the base material of the coating, so that the concentration of the aluminum powder is 0....

Abstract

The invention relates to an electronic heating device, comprising a suction nozzle, a housing, a heating component and a power component. The heating component includes a heating pipe and a heat-insulating pipe; a baking cavity is arranged in the heating pipe; the wall of the heat-insulating pipe is coated with a heat-insulating coating layer; the heating pipe is sleeved with the heat-insulating pipe; a gap passage is formed between the heat-insulating pipe and the heating pipe in mutually spaced manner; the heat-insulating pipe is provided with a gas guide hole whereby a receiving cavity is communicated with the gap passage. The heat-insulating coating layer can reflect thermal radiation of the heating pipe so that heat in the baking cavity is avoided being directly transmitted to the housing. A gap is provided between the heat-insulating pipe and the heating pipe, external cold air can enter the receiving cavity from a gas inlet and may enter the gap passage via the gas guide hole, and the temperature of the heating pipe and the heat-insulating pipe is reduced during suction. The cooling design measures such as the heat-insulating coating layer and flow promotion enable the electronic heating device is simple in structure and good in heat-insulating effect.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic heating device. Background technique [0002] Modern humans have realized the harm of cigarettes to human health and the pollution of cigarette smoke to the atmospheric environment, especially the indoor environment. With the improvement of the quality of life, people gradually pay more attention to their own health and the society pays more attention to the external environment, especially the indoor environmental pollution. It is imperative to quit smoking. In order to solve the excessive dependence of "addicts" on traditional cigarettes, electronic cigarettes have emerged in recent years. [0003] Electronic cigarettes are generally divided into e-liquid type and dry-burning type. E-liquid-type e-cigarettes generally generate mist by atomizing liquid e-liquid for users to smoke. Dry-burning e-cigarettes generally heat and bake solid tobacco leaves,...
