The main body has an opening located on one side, an inner casing corresponding to the opening, and a peristaltic pump provided on a side of the inner casing not facing the opening. The inner casing defines an essential oil bottle accommodation space communicating with the opening, and the essential oil bottle accommodation space is provided for disposing an essential oil bottle storing an essential oil. The peristaltic pump is controlled by the main body, thereby fixed quantity of essential oil is supplied regularly and quantitatively by the humidifier without dismounting the water storage bucket. Thus, fragrance is kept in atomizing air continuously to solve the problem of the conventional humidifier that fragrance merely exists when the essential oil is added initially. ## Claims ### Claim 1 A humidifier with regular addition of fixed quantity of essential oil, the humidifier including a main body, and a water storage bucket assembling with the main body, the main body comprising a temporary liquid storage basin, an atomizing space defined by the temporary liquid storage basin, an atomizing plate disposed within the temporary liquid storage basin, a projecting stud disposed within the temporary liquid storage basin, a fan generating air stream within the atomizing space after being started, and a startup management module connected to the fan and the atomizing plate, a high water level line is defined on the temporary liquid storage basin, the water storage bucket comprising a bucket body, a water supply switch provided on the bucket body and pushed by the projecting stud to permit water stored in the water storage bucket to flow into the temporary liquid storage basin, and an air guiding passage defined and formed by the bucket body while communicated to the atomizing space without being used for water storage; and the humidifier characterized in that: the main body comprises at least one opening located on one side, an inner casing disposed inside the main body and corresponding to the opening, and a peristaltic pump provided on a side of the inner casing not facing the opening, the inner casing defines an essential oil bottle accommodation space communicating with the opening, the inner casing is disposed with a through hole and an tube, wherein the through hole is provided for a transmission shaft of the peristaltic pump to pass through, and one end of the tube faces the temporary liquid storage basin, the humidifier comprises a peristaltic pump head provided in the essential oil bottle accommodation space and driven by the peristaltic pump, in the peristaltic pump head is provided with a plurality of rollers driven by the transmission shaft, and a liquid delivering hose disposed between the plurality of rollers, one end of the liquid delivering hose reaches into an essential oil bottle, and another end is connected to the tube. ### Claim 2 (depends on 1) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 1, wherein the main body comprises a lid disposed corresponding to the opening to seal the essential oil bottle accommodation space. ### Claim 3 (depends on 1) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 1, wherein the inner casing comprises two limit plates spaced apart from each other, a pump head installation zone is defined by the two limit plates, and the through hole and one end of the tube are located in the pump head installation zone. ### Claim 4 (depends on 3) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 3, wherein the inner casing comprises a connecting plate connected to the two limit plates and the pump head installation zone is defined by the connecting plate together with the two limit plates. ### Claim 5 (depends on 3) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 3, wherein the peristaltic pump head is provided with a connecting arm on both sides respectively, and each of the two limit plates comprises a positioning structure assembled with the connecting arm. ### Claim 6 (depends on 5) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 5, wherein one end of the connecting arm assembled with the positioning structure is provided with a hook. ### Claim 7 (depends on 6) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 6, wherein each positioning structure is a through hole providing for one of the hooks to dispose. ### Claim 8 (depends on 1) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 1, wherein the main body comprises a protective cover disposed on a side of the inner casing that does not face the opening and covering the peristaltic pump. ### Claim 9 (depends on 1) The humidifier with regular addition of fixed quantity of essential oil as claimed in claim 1, wherein the main body includes a plurality of control switches connected to the startup management module and exposed outside the main body.
