Description

CROSS-REFERENCE TO PRIOR APPLICATION Priority is claimed to Chinese Patent Application No. 202111408312.2, filed on Nov. 19, 2021, the entire disclosure of which is hereby incorporated by reference herein. FIELD The invention relates to the field of vaporization, and more particularly, to a composite liquid guide cotton, a heating assembly, a vaporizer and an electronic vaporization device. BACKGROUND An electronic vaporization device is mainly composed of a vaporizer and a power supply device. The power supply device is used to supply power to the vaporizer, and the vaporizer can heat and vaporize vaporization liquid stored in the vaporizer after being powered on. In general, the vaporizer includes a liquid guide cotton and a heating member in contact with the liquid guide cotton. The vaporization liquid stored in the vaporizer is adsorbed by the liquid guide cotton, and the heating member heats the vaporization liquid absorbed by the liquid guide cotton after being powered on. The liquid guide cotton is prone to burning if its temperature resistance is not enough. Since it takes some time for the absorption and conduction of the vaporization liquid in the liquid guide cotton, if the liquid absorbing speed and liquid guiding speed of the liquid guide cotton are too slow, the vaporized gas generated after vaporization will be dry and light, the fragrance release is not sufficient, and in severe cases, dry burning may even occur and results in burning smell. SUMMARY In an embodiment, the present invention provides a composite liquid guide cotton for a vaporizer, the composite liquid guide cotton comprising: at least one heat resistant layer, at least one first isolation layer, at least one rapid liquid guide layer, and at least one second isolation layer that are stacked in sequence, wherein the heat resistant layer is configured to contact a heating body and comprises a high-temperature resistant material, and wherein a liquid guide rate of the rapid liquid guide layer is higher than a liquid guide rate of the first isolation layer and the second isolation layer.

DETAILED DESCRIPTION In an embodiment, the present invention provides an improved composite liquid guide cotton, and a heating assembly, vaporizer and electronic vaporization device having the composite liquid guide cotton. In an embodiment, the present invention provides a composite liquid guide cotton for a vaporizer. The composite liquid guide cotton includes at least one heat resistant layer, at least one first isolation layer, at least one rapid liquid guide layer and at least one second isolation layer that are stacked in sequence. The heat resistant layer is used to contact with a heating body and is made of a high-temperature resistant material, and the liquid guide rate of the rapid liquid guide layer is higher than that of the first isolation layer and the second isolation layer. In some embodiments, the number of layers of the rapid liquid guide layers is two. In some embodiments, the number of layers of each of the heat resistant layer, the first isolation layer, and the second isolation layer is one. In some embodiments, the rapid liquid guide layer is wood pulp cotton. In some embodiments, the wood pulp cotton has a weight of 50 g±10% per square meter before soaking. In some embodiments, the heat resistant layer when soaked with vaporization liquid has a temperature resistance of 300° C.
