FIELD The present invention relates to the technical field of electronic vaporization devices, and in particular, to a vaporizer, an electronic vaporization device, and a liquid guiding mechanism. BACKGROUND A vaporizer is a device that vaporizes liquid (such as e-liquid) into gases or tiny particles, and is widely used in apparatuses such as medical equipment, or an e-cigarette. Currently, the vaporizer generally includes a bottom plate, a vaporization base, and a vaporization core. The vaporization base is arranged on and covers the bottom plate and cooperates with the bottom plate to form a vaporization cavity. The vaporization core is accommodated in the vaporization cavity for heating and vaporizing the liquid in the vaporization cavity when energized. Specifically, air inlet holes are also provided on the bottom plate, and one end of each air inlet hole is in communication with external air, and the other end is in communication with the vaporizer, so that the external air can enter the vaporization cavity through the air inlet holes. However, a large amount of liquid will accumulate on a side surface of the bottom plate facing the vaporization base during use of an existing vaporizer, and will leak out through the air inlet holes of the bottom plate, resulting in liquid leakage. SUMMARY In an embodiment, the present invention provides a vaporizer, comprising: a bottom plate comprising a first surface and a second surface arranged oppositely; a vaporization base arranged on and covering the first surface of the bottom plate and cooperating with the first surface of the bottom plate to form a vaporization cavity; a vaporization core accommodated in the vaporization cavity, the vaporization core being configured to heat and vaporize liquid in the vaporization cavity when energized; and a liquid guiding assembly configured to absorb liquid on the bottom plate, the liquid guiding assembly comprising: a first liquid guiding portion arranged on the first surface of the bottom plate and cooperating with the first surface of the bottom plate to form at least one first liquid guiding channel; and a second liquid guiding portion comprising at least one second liquid guiding channel, one end of the second liquid guiding channel being in communication with the first liquid guiding channel, wherein a horizontal size of the first liquid guiding channel decreases gradually in a direction toward the second liquid guiding portion, and wherein a capillary force of the second liquid guiding channel is greater than a capillary force of the first liquid guiding channel such that liquid absorbed by the first liquid guiding portion by the capillary force of the first liquid guiding channel is guidable to the second liquid guiding portion.
