The kanji 毎 is a phono-semantic compound (形声文字, けいせいもじ). The phonetic component is 母 (bo), which represents the sound "mai." The semantic component is likely related to the idea of a cycle or repetition. Thus, the kanji combines a sound component with a meaning component related to frequency and regularity. The original form of the character might have depicted a person repeatedly doing something, which gradually evolved into its current form. However, there is no solid source for this specific origin.
